Prospective evaluation of unilateral adrenal masses in patients with operable non-small-cell lung cancer.
Authors: Ettinghausen S E , Burt M E
Published: February 2017

Although adrenal metastases are frequently noted with non-small-cell lung cancer (NSCLC) at autopsy, their incidence in patients with operable NSCLC is unclear. We prospectively assessed consecutive patients with otherwise operable NSCLC for the incidence and histology of unilateral adrenal masses. Assessment included blood chemistries, lung function tests, bronchoscopy, chest x-ray, bone scan, and computed tomography (CT) of the head, chest, and upper abdomen. Of 246 patients with otherwise operable NSCLC, 10 (4.1%) had a unilateral adrenal mass. Unilateral adrenal masses were needle-aspirated under CT control. If cytology was nondiagnostic, adrenalectomy was performed. Four (40%) of 10 patients had adrenal metastases proven by needle aspiration. Of the six (60%) patients with benign unilateral adrenal masses, one was demonstrated by needle aspiration. In the other five patients, a nondiagnostic needle aspiration led to adrenalectomy, which yielded two adenomas, two hyperplastic nodules, and one hemorrhagic cyst. There was no significant difference between the patients with benign and metastatic unilateral adrenal masses with respect to patient age or stage and size of adrenal mass. Patients with benign unilateral adrenal masses underwent curative resection of their NSCLC and had significantly prolonged survival compared with patients with metastatic unilateral adrenal masses treated with chemotherapy (P = .037). Median survival of patients with benign and metastatic unilateral adrenal masses was greater than 30 months and 9 months, respectively. In conclusion, the presence of unilateral adrenal masses in patients with otherwise operable NSCLC should not preclude thoracotomy without pathologic proof of metastatic disease.

Diaziquone (AZQ), a synthetic quinone with demonstrated activity against acute nonlymphocytic leukemia (ANLL), primary CNS tumors, and non-Hodgkin's lymphoma (NHL), is virtually devoid of nonhematopoietic toxicity at conventional doses. As a prelude to its inclusion into bone marrow transplant (BMT) preparative regimens, a phase I study of high-dose AZQ with autologous BMT (ABMT) was performed. Patients with refractory solid tumors and lymphomas were treated with a single 24-hour infusion of AZQ at 50 to 355 mg/m2 in dose escalations of 20%. Fifty-six patients received 69 courses. Those receiving greater than 60 mg/m2 had nadir granulocyte and platelet counts less than 500/microL and 20,000/microL, respectively. Nausea, vomiting, stomatitis, and diarrhea were mild, transient, and not dose-related. Transient minimal elevations of liver function tests were seen in five patients and were also not dose-related. The maximally tolerated dose (MTD) of high-dose AZQ was found to be 245 mg/m2, with nephrotoxicity being dose-limiting. Significant azotemia was seen in four of 12 patients treated at 295 and 355 mg/m2, including fatal anuric renal failure in three of these patients. Reversible proteinuria also occurred in 24 of 26 courses above 150 mg/m2, including nephrotic range proteinuria in eight courses, all at doses of 205 to 355 mg/m2. The proteinuria was also associated with multiple proximal tubular defects including generalized aminoaciduria and proximal renal tubular acidosis. There were six early deaths including two of early renal failure (295 and 355 mg/m2), two of sepsis (205 and 245 mg/m2), one of a pulmonary embolus (85 mg/m2), and one of progressive disease (60 mg/m2). Of 50 patients who were assessable for response, there were seven responses including two of 10 with primary CNS tumors, one of 12 with malignant melanoma, one of five with non-small-cell lung carcinoma, two of two with breast carcinoma, and one of one with ovarian carcinoma. Because of its activity in ANLL and NHL and its unique toxicity spectrum, high-dose AZQ may improve the efficacy of current BMT preparative regimens without significantly increasing their nonhematopoietic toxicity.

Published: February 2017

PURPOSE

Recombinant human macrophage colony-stimulating factor (M-CSF) has been shown to stimulate specifically macrophage lineage differentiation in vitro and to induce cells capable of antitumor activity alone or in combination with an antibody. The administration of M-CSF to mice has demonstrated antitumor therapeutic effects in vivo. Therefore, a phase I trial of M-CSF administration to patients with metastatic cancer was undertaken.

PATIENTS AND METHODS

M-CSF was given by intermittent intravenous bolus infusion every 8 hours for 7 days; the treatment cycle was repeated once after a week of rest. Cohorts of three patients underwent dose escalation from 10 to 100,000 micrograms/m2/d; 23 patients received 27 courses of M-CSF administration. All patients had metastatic solid tumors refractory to conventional therapy, including renal cell carcinoma (RCC) (nine), melanoma (seven), and colorectal carcinoma (seven).

RESULTS

Treatment-related toxicity was minimal; five patients developed transient signs of ocular or periorbital inflammation, with iridocyclitis as the most severe manifestation. At the highest doses, platelet counts decreased with therapy (but remained > 100,000/mm3) and the absolute monocyte count increased during the course of therapy. Only at 30,000 and 100,000 micrograms/m2/d was treatment limited because of toxicity (iritis and malaise). Pharmacokinetic studies demonstrated up to a 1,000-fold increase in circulating serum M-CSF after bolus infusion; half-life varied from 1 to 6 hours. Complete regression of mediastinal adenopathy and multiple pulmonary metastases were observed in one patient with RCC.

CONCLUSION

Recombinant M-CSF can be administered safely to patients with metastatic cancer at doses that demonstrate biologic activity.
Autologous versus allogeneic bone marrow transplantation for non-Hodgkin's lymphoma: a case-controlled analysis of the European Bone Marrow Transplant Group Registry data.

Published: February 2017

PURPOSE

A case-controlled study of patients who reported to the European Bone Marrow Transplant Group (EBMTG) was performed to investigate the relative roles and efficacy of allogeneic (alloBMT) and autologous bone marrow transplantation (ABMT) in non-Hodgkin's lymphoma.

PATIENTS AND METHODS

Of 1,060 patients who reported to the lymphoma registry, 938 patients underwent ABMT and 122 patients underwent alloBMT. A case-controlled study was performed by matching 101 alloBMT patients with 101 ABMT patients. The case matching was performed after the selection of the main prognostic factors for progression-free survival by a multivariate analysis.

RESULTS

The progression-free survival was similar in both types of transplants (49% alloBMT v 46% ABMT). The overall relapse and progression rate for the alloBMT patients was 23% compared with 38% in the ABMT patients. This difference was not significant statistically. In the lymphoblastic lymphoma subgroup, alloBMT was associated with a lower relapse rate than ABMT (24% alloBMT v 48% ABMT; P = .035). The progression-free survival, however, was not significantly different because patients with lymphoblastic lymphoma who underwent alloBMT had a higher procedure-related mortality (24% alloBMT v 10% ABMT; P = .06). A significantly lower relapse/progression rate was also observed in patients with chronic graft-versus-host disease (cGVHD) compared with those patients without (0% cGVHD v 35% no cGVHD; P = .02). Fourteen of 18 patients who had cGVHD also had lymphoblastic lymphoma.

CONCLUSION

This study suggests that ABMT and alloBMT for non-Hodgkin's lymphoma are comparable, with the exception of lymphoblastic lymphoma in which a graft-versus-lymphoma effect may account for the lower relapse rate for patients who underwent alloBMT.
High-dose consolidation therapy with autologous stem-cell rescue in stage IV breast cancer: follow-up report.
Authors: Williams S F , Gilewski T , Mick R , Bitran J D
Published: February 2017

PURPOSE

Fifty-nine patients with newly diagnosed metastatic breast cancer were treated with induction chemotherapy followed by high-dose intensification and autologous stem-cell rescue (ASCR) to determine therapeutic efficacy.

PATIENTS AND METHODS

Induction consisted of cyclophosphamide, doxorubicin, vincristine, and methotrexate with leucovorin rescue (LOMAC) in 27 patients, or fluorouracil, cisplatin, doxorubicin, and cyclophosphamide (FCAP) in 32 patients. Intensification after LOMAC was cyclophosphamide and thiotepa (CyTepa) with ASCR, and after FCAP it was cyclophosphamide, thiotepa, and carmustine (BCNU) in all but eight patients who received CyTepa.

RESULTS

Median survival from study entry for the entire group was 13.3 months. Median time to progression from reinfusion for the 45 patients who underwent intensification was 7.5 months. After LOMAC and intensification, there were 12 complete responses (CR) (nine partial responses [PRs] after induction converted to CRs). Responses after FCAP and intensification were eight CRs (two PRs after induction converted to CRs). Median time to treatment failure from reinfusion was 5.4 months for LOMAC and intensification, and was 10.5 months for FCAP and intensification. Median survival from study entry was 15.1 months for all 27 LOMAC patients and 9.3 months for all 32 FCAP patients. Median time to treatment failure from reinfusion for 11 patients who were CRs at intensification has not been reached and is more than 13 months compared with a median of 5.5 months for the 23 patients in partial remission at intensification.

CONCLUSIONS

High-dose intensification therapy has led to increased CR rates in metastatic breast cancer. The role of such therapy in the treatment of stage IV breast cancer requires further refinement.

Gemcitabine in leukemia: a phase I clinical, plasma, and cellular pharmacology study.
Authors: Grunewald R , Kantarjian H , Du M , Faucher K , Tarassoff P , Plunkett W
Published: February 2017

PURPOSE

Phase I clinical and in vitro studies of gemcitabine (2',2'-difluorodeoxycytidine; dFdC) have demonstrated that the accumulation rate of dFdC 5'-triphosphate (dFdCTP) in mononuclear and leukemia cells is saturated when plasma or extracellular dFdC levels exceed 15 to 20 mumol/L. Thus, we designed a phase I study to maximize the accumulation of dFdCTP by leukemia cells by administering dFdC at 10 mg/m2/min, a dose rate calculated to produce steady-state plasma dFdC levels that exceed 15 to 20 mumol/L.

PATIENTS AND METHODS

The treatment intensity was increased in patients (n = 22) with relapsed or refractory acute leukemia or chronic myelogenous leukemia (CML) in blast crisis by prolonging the infusion duration but maintaining the same rate. Doses of dFdC between 1,200 mg/m2 and 6,400 mg/m2 were administered weekly for 3 weeks.

RESULTS

The maximum-tolerated dose was 4,800 mg/m2 infused over 480 minutes. The mean steady-state dFdC level in plasma of all infusions was 26.5 +/- 9 mumol/L (n = 19). The accumulation rates of dFdCTP in circulating leukemia cells varied greatly among patients but remained linear in eight patients infused for 120 to 240 minutes, and up to or beyond 360 minutes in five of eight additional patients. Elimination of dFdCTP was significantly related to its cellular concentration: blasts with greater than 450 mumol/L dFdCTP exhibited biphasic elimination, whereas blasts with lower dFdCTP concentrations exhibited linear kinetics. Biphasic elimination was associated with higher dFdCTP areas under the concentration-times-time curve (AUCs) and greater inhibition of DNA synthesis.

CONCLUSION

Studies of the cellular pharmacology and pharmacodynamics of dFdC may be useful in optimizing protocol designs for leukemia.
High-dose carboplatin and etoposide with autologous bone marrow transplantation in refractory germ cell cancer: an Eastern Cooperative Oncology Group protocol.

Published: February 2017

PURPOSE

A phase II trial was undertaken to assess the feasibility, toxicity, and efficacy of high-dose carboplatin and etoposide with autologous bone marrow transplantation in patients with relapsed or refractory germ cell tumors.

PATIENTS AND METHODS

Forty patients with recurrent germ cell cancer received carboplatin 500 mg/m2 and etoposide 400 mg/m2 given at 7, 5, and 3 days before marrow infusion. Autologous marrow infusion (day 0) was accomplished using one half of the bone marrow harvested before chemotherapy. Patients who achieved a complete or partial response with the first cycle of treatment received a second identical cycle of chemotherapy followed by infusion of the remaining cryopreserved bone marrow.

RESULTS

Objective responses were obtained in 17 of the 38 patients (45%) assessable for response, including eight partial and nine complete remissions. Five of these patients remain in continuous complete remission with minimal follow-up of 1 year. Toxicity encountered was primarily hematologic, and five patients (13%) died of treatment-related complications. Significant toxicities often seen with high-dose cisplatin (ototoxicity, neurotoxicity, and renal toxicity) were manageable in this regimen of high-dose carboplatin.

CONCLUSIONS

This trial confirms the curative potential of high-dose carboplatin and etoposide in highly refractory germ cell cancer.
Elevated circulating levels of tumor necrosis factor predict unresponsiveness to treatment with interferon alfa-2b in chronic myelogenous leukemia.
Authors: Herrmann F , Helfrich S G , Lindemann A , Schleiermacher E , Huber C , Mertelsmann R
Published: February 2017

PURPOSE

The study was undertaken to analyze circulating tumor necrosis factor (TNF) levels in patients with chronic-phase chronic myelogenous leukemia (CML) undergoing interferon (IFN) alfa-2b therapy, and to correlate pretreatment serum levels of TNF with response to IFN alfa-2b therapy.

PATIENTS AND METHODS

Fourteen patients with CML in chronic phase were treated with recombinant human IFN alfa-2b for 7 to 39 months.

RESULTS

In eight patients IFN alfa-2b treatment failed due to lack of hematologic response. A complete or partial hematologic remission was achieved in the remaining six patients, of whom two patients experienced a complete cytogenetic response. Retrospective analysis of serum samples obtained from all patients before the onset of IFN alfa-2b administration revealed that levels (mean +/- SEM) of circulating TNF were higher (P less than .001) in the group of patients who did not respond to IFN alfa-2b treatment (157 +/- 15 U/mL) than in the responders (10.3 +/- 4 U/mL) or healthy control subjects (9.1 +/- 3 U/mL). However, there was no correlation between TNF serum levels and other patient characteristics at study enrollment including age, sex, duration of disease, performance status, splenomegaly, WBC count, platelet count, hemoglobin value, prior therapy, and prognostic category.

CONCLUSION

These findings indicate that circulating levels of TNF are increased in a subset of patients with chronic-phase CML and that this elevation is associated with poor response to IFN alfa-2b therapy.
Bone marrow transplantation of chronic myelogenous leukemia in chronic phase: evaluation of risks and benefits.
Authors: Wagner J E , Zahurak M , Piantadosi S , Geller R B , Vogelsang G B , Wingard J R , Saral R , Griffin C , Shah N , Zehnbauer B A
Published: February 2017

PURPOSE

Allogeneic bone marrow transplantation (BMT) is an option for some patients with chronic myelogenous leukemia (CML). We retrospectively evaluated the effect of various risk factors observed at diagnosis and at transplantation on survival, event-free survival (EFS), and relapse after BMT.

PATIENTS AND METHODS

Seventy-nine patients with CML in chronic phase (CP) were treated with cyclophosphamide and total body irradiation followed by BMT. Graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine (CsA) in most instances or CsA plus the use of lymphocyte-depleted bone marrow (BM).

RESULTS

Survival at 4.5 years was 52%. Stratified by age and GVHD prophylaxis, the actuarial survival was 65% (95% confidence interval [CI], 47% to 78%) in patients aged less than 30 years receiving unmanipulated BM, 33% (95% CI, 12% to 56%) in patients greater than or equal to 30 years old receiving unmanipulated BM, and 38% (95% CI, 14% to 63%) in patients greater than or equal to 30 years old receiving lymphocyte-depleted BM. In univariate analysis, patient age (greater than or equal to 30 years) and the use of lymphocyte-depleted BM negatively influenced EFS. When stratified by age and GVHD prophylaxis, however, ABO incompatibility, cytomegalovirus (CMV) seropositivity, and chronic GVHD significantly reduced the probability of EFS. Factors that have been associated with early death in nontransplanted patients (ie, sex, spleen size, blast and platelet counts at presentation) were not predictive of long-term survival outcome after BMT.

CONCLUSIONS

The data suggest that (1) BMT should be offered early after diagnosis to all patients with CML in CP who have compatible sibling donors regardless of prognostic factors at presentation, (2) GVHD remains the principal cause of mortality after BMT in patients receiving CsA, and (3) T-cell depletion by the physical separation method of counterflow elutriation (CE) is associated with a significant risk of relapse.
Prolonged continuous intravenous infusion interleukin-2 and lymphokine-activated killer-cell therapy for metastatic renal cell carcinoma.
Authors: Thompson J A , Shulman K L , Benyunes M C , Lindgren C G , Collins C , Lange P H , Bush W H , Benz L A , Fefer A
Published: February 2017

PURPOSE

Two consecutive protocols of continuous intravenous (CIV) infusion interleukin-2 (IL-2) and lymphokine-activated killer (LAK) cells were carried out in patients with metastatic renal cell carcinoma (RCC) to determine the response rate and toxicity.

PATIENTS AND METHODS

In both protocols, patients received induction IL-2 at 6 x 10(6) U/m2/d on days 1 to 5, and underwent leukapheresis on days 7 to 9 at the peak of rebound lymphocytosis. LAK cells were generated by a 5-day incubation with IL-2 at 1,000 U/mL, and were infused on days 12 to 14. For the first 20 patients (protocol A), maintenance IL-2 was administered at 6 x 10(6) U/m2/d on days 12 to 16. On the assumption that less IL-2 might be required to maintain rather than to induce LAK activity, and that a longer duration of maintenance IL-2 might enhance LAK survival and function in vivo, the protocol for the subsequent 22 patients (protocol B) was altered so that the maintenance phase consisted of a lower dose of IL-2 (2 x 10(6) U/m2/d) administered for a longer period of time (days 10 to 20).

RESULTS

In protocol A, there were two complete responses (CRs) and three partial responses (PRs), for a total response rate of 25%. One PR was surgically converted into a CR. The durations of the CRs are 36+, 18+, and 18+ months. Hypotension and capillary leak were most severe during maintenance, which limited the median duration of maintenance IL-2 to 4 days. In protocol B, no patient experienced severe hypotension, and the median duration of maintenance IL-2 was 9 days. Two patients exhibited a CR and seven a PR, for a total response rate of 41%. Two PRs were surgically converted to CRs. The durations of CR are 14+, 9+, 6+, and 5+ months. In both protocols, the CIV induction regimen resulted in marked rebound lymphocytosis (mean, 11,097/microL) and LAK-cell yield (mean, 18.1 x 10(10)). The cumulative response rate was 14 of 42 patients, or 33% (95% confidence interval, 19% to 47%).

CONCLUSION

These results demonstrate that both protocols of CIV IL-2 plus LAK cells have substantial antitumor activity, and that a longer maintenance phase of IL-2 at a lower dose is associated with significantly less toxicity without a loss of therapeutic efficacy.
Association of HLA phenotype with response to active specific immunotherapy of melanoma.
Authors: Mitchell M S , Harel W , Groshen S
Published: February 2017

PURPOSE

Only a proportion of patients with disseminated melanoma who were immunized successfully with a therapeutic melanoma vaccine (theraccine) had a major clinical response. We investigated whether there was a correlation between their HLA phenotypes and the likelihood of a clinical response.

PATIENTS AND METHODS

Seventy patients with disseminated melanoma who were treated with melanoma theraccine were HLA-typed serologically. The two melanoma cell lines used in the theraccine also were typed by serology and cDNA probes (for class II). Results were analyzed to see whether any alleles were present or absent in responders consistently.

RESULTS

The HLA class I alleles A2 (and the cross-reacting A28), B12 (and its split B44 and B45), and C3 were found to be associated with clinical remission. The effects of these alleles on response were apparent when two or more of the alleles were analyzed together. There was a 38% response rate in those 24 patients with two or three of the alleles compared with 20% in the group as a whole.

CONCLUSIONS

These data support two distinct possibilities between which we cannot yet distinguish. Responses may be more likely when there is a close match between the HLA molecules in the theraccine and the patients' own molecules. Alternatively, certain types of HLA class I molecules present in the patients may facilitate rejection of autochthonous melanomas by efficiently presenting melanoma-associated antigens to cytotoxic T cells.
Pharmacokinetics and pharmacodynamics of medroxyprogesterone acetate in advanced breast cancer patients.
Authors: Etienne M C , Milano G , Frenay M , Renee N , Francois E , Thyss A , Schneider M , Namer M
Published: February 2017

PURPOSE

Medroxyprogesterone acetate (MPA) is one of the major drugs used in endocrine therapy for advanced breast cancer. However, its optimal dose still has not been clearly established. Response to treatment and drug-related side effects were analyzed as a function of plasma MPA concentrations during prolonged MPA treatment.

PATIENTS AND METHODS

MPA plasma concentrations were measured (high-performance liquid chromatography [HPLC] assay) at steady state (Css min) in 129 patients (mean age, 63 years; range, 34 to 87) treated by MPA (86% were treated orally exclusively with daily doses ranging from 400 to 2,000 mg).

RESULTS

A wide interpatient variability was noted in MPA Css min for the 70 patients who received 1,000 mg/d orally (median, 51 ng/mL; range, 10 to 269 ng/mL). Intrapatient analysis of the evolution of MPA Css min during prolonged treatment showed relative stability of MPA concentrations (mean CV, 20.6%). A weak but significant correlation was demonstrated between oral doses and MPA Css min (P = .016). Thirty-five percent of patients (45 of 129) developed MPA-related side effects that were associated with the highest plasma MPA concentrations; medians were 81 and 32 ng/mL for toxic and nontoxic treatments, respectively (P less than .001). Objective response was assessable in 55 patients who were treated by MPA exclusively. Plasma MPA concentrations were significantly different (P = .025) between patients with progressive disease (PD) (median, 46 ng/mL) and those with complete response (CR), partial response (PR), or stable disease (SD) (median 65 ng/mL). Comparison of CR plus PR versus SD versus PD showed only a tendency toward significant differences in MPA Css min (P = .07). Analysis of toxicity and response as a function of the oral dose did not show any significant relationship. These data suggested an optimal therapeutic window for MPA Css min located within 50 to 70 ng/mL.

CONCLUSION

This study demonstrates that plasma MPA concentration, as opposed to the administered dose, is a determining factor for toxicity and response therapy [corrected].
Pharmacokinetics and metabolism of 4'-iodo-4'-deoxy-doxorubicin in humans.
Authors: Robert J , Armand J P , Huet S , Klink-Alakl M , Recondo G , Hurteloup P
Published: February 2017

PURPOSE

4'-iodo-4'-deoxydoxorubicin is a new anthracycline that currently is under clinical evaluation. To improve the management of future trials, we have determined its pharmacokinetics and metabolism during a phase I/II study and have tried to relate the parameters obtained to the hematologic toxicity of the drug in terms of the survival of blood cells.

PATIENTS AND METHODS

The pharmacologic study included 19 patients who were entered at dose levels that ranged between 6 and 90 mg/m2; nine patients were treated at 80 mg/m2, which is close to the maximum recommended dose level. Blood sampling was performed from the end of the bolus infusion to 48 hours after treatment. Drug and metabolites were extracted and analyzed by high-performance liquid chromatography (HPLC), and the data were processed by nonlinear fitting to multicompartment models.

RESULTS

Plasma concentrations were best fitted to a three-compartment model with half-lives of 5.2 minutes, 0.79 hours, and 10.3 hours. The total body clearance and volume of distribution at steady state were high (350 L/h/m2 and 2,065 L/m2). The drug was metabolized extensively to a 13-dihydroderivative, 4'-iodo-4'-deoxy-doxorubicinol; the mean area under the curve (AUC) ratio metabolite/parent drug was the highest observed ever for an anthracycline (12.1 +/- 7.4); the metabolite was cleared from the plasma with an elimination half-life of 15.3 hours. The AUCs of the parent compound and its metabolite were related linearly to the dose administered, and showed no saturation phenomenon. Urinary excretion was studied in nine patients and showed a cumulative elimination of less than 6% of the dose administered, two thirds of which were eliminated in the first 12 hours after injection. Ninety-three percent to 100% of the elimination of fluorescent compounds occurred in the form of the metabolite. Drug concentration in five tumor samples showed a rapid uptake of the drug from plasma and a preferential uptake of the parent drug compared with the metabolite. Blood cell counts after 4'-iodo-4'-deoxydoxorubicin treatment showed significant correlations among the surviving fractions of both granulocytes and platelets and the AUCs of the parent drug and its metabolite; the most significant correlations were obtained for the granulocytes and the metabolite. Significant correlations between AUCs and blood-cell survivals were maintained, even if only the nine patients treated at the dose of 80 mg/m2 were taken into account for the computation.

CONCLUSIONS

Our results especially show that myelosuppression that is induced by 4'-iodo-4'-deoxydoxorubicin can be well predicted by the measure of the AUC of the drug and its metabolite. This could be used for the further development of the drug toward high-dosage schedules.
Role of technetium 99m-labeled monoclonal antibody in the management of melanoma patients.
Authors: Blend M J , Ronan S G , Salk D J , Gupta T K
Published: February 2017

PURPOSE

A study was performed to assess the usefulness of a radiolabeled monoclonal antibody (MoAb; technetium 99m NR-ML-05 Fab) as a detecting agent, as well as to evaluate its role in the overall decision-making process in the management of cutaneous malignant melanoma.

PATIENTS AND METHODS

Twelve patients with histologically confirmed primary cutaneous melanoma and palpable regional nodes were injected with MoAb NR-ML-05 Fab, radiolabeled with 20 to 30 mCi of 99mTc. Whole-body anterior and posterior images were obtained. Left and right lateral views of the head and anterior and posterior views of the chest, abdomen, pelvis, and extremities were obtained, as were selected single-photon emission computed tomographic (SPECT) views of regional lymph nodes and areas of known or suspected lesions.

RESULTS

In nine of 12 patients, clinical and/or MoAb evolution identified 30 discrete sites of suspected melanoma. The remaining three patients showed no positive sites, and there was no evidence of metastatic melanoma. All 30 sites were examined microscopically, and melanoma was confirmed histologically in 23. The remaining seven were negative. MoAb imaging detected 21 (true-positive) but failed to detect two (false-negative) lesions. Sensitivity was 91% (21 of 23); positive predictive value was 95% (21 to 22).

CONCLUSIONS

MoAb imaging seems to provide an excellent way to obtain information with regard to the metastatic status of melanoma patients. Immunocytochemistry showed that MoAb (NR-ML-05) is as sensitive as the S-100 antibody and probably more sensitive than the commercially available antimelanoma antibody HMB-45.
Educational, occupational, and insurance status of childhood cancer survivors in their fourth and fifth decades of life.
Authors: Hays D M , Landsverk J , Sallan S E , Hewett K D , Patenaude A F , Schoonover D , Zilber S L , Ruccione K , Siegel S E
Published: February 2017

PURPOSE

Survivors of childhood cancer who are now greater than or equal to 30 years of age are available for study in significant numbers for the first time. An evaluation of their educational achievement, current employment status, frequency of problems in the work-place, and ability to obtain affordable health and life insurance was the aim of this study.

PATIENTS AND METHODS

This was a case-control study of 219 childhood cancer survivors with individually matched controls from two tertiary-care pediatric centers. Telephone interviews were used and drew on a 356-item basic instrument for both subjects and controls. Medical (including intensity of therapy), marital, and psychosocial areas were included in the survey, but statistical comparisons concentrated on educational and economic issues.

RESULTS

The overall current status of survivors and controls in the relevant areas, ie, education, employment, and insurance, was similar. A history of employment discrimination for entry into the uniformed services and in other special situations, and life insurance discrimination during the initial years after the completion of therapy was noted. Survivors experienced few problems in the work-place. Survivors of CNS tumors were unique, with problems in many of the areas studied, although there were notable individual exceptions.

CONCLUSION

With the exception of those individuals with CNS tumor histories, survivors who were treated in the era of 1945 to 1975 had few economic sequelae of cancer or its therapy that extended beyond the first decades after treatment.

PURPOSE

To evaluate the impact on survival of the attainment of surgically defined favorable responses (S-R) to salvage intraperitoneal (IP) chemotherapy after initial systemic cytotoxic drug delivery.

PATIENTS AND METHODS

We examined the survival of patients who were treated on one of three phase II IP trials that were conducted at the Memorial Sloan-Kettering Cancer Center. A total of 58 patients whose largest residual tumor masses measured less than or equal to 0.5 cm in maximum diameter at the initiation of this salvage therapy were assessable for response, 28 of whom (48%) demonstrated a S-R, which included 19 (33%) who achieved a surgically defined complete response (S-CR).

RESULTS

With a median follow-up of 43+ months (range, 33+ to 58+ months) from the initiation of IP therapy, 12 of 19 (63%) have recurred. The median duration of S-CR for the 10 patients with microscopic residual disease was 32 months compared with 15 months for the nine patients with macroscopic residual disease (largest tumor mass less than or equal to 0.5 cm; P greater than .1). For patients with microscopic residual disease who experienced a S-CR (n = 10) after salvage IP therapy, the median overall survival from the initiation of therapy has not been reached, but will exceed 4 years compared with a 25-month median survival for the nonresponding patients (n = 13; P = .004). The median survival for the 18 patients with small-volume macroscopic disease who responded to therapy was 40 months compared with 19 months for the nonresponders (P = .009).

CONCLUSION

Although the results of this evaluation are encouraging and suggest that the attainment of a S-R, particularly a S-CR, after IP chemotherapy may result in a clinically meaningful favorable impact on survival, a randomized controlled trial will be required to address definitively this important issue.

Authors: Bukowski R M , Wolfe M , Levine H S , Crawford D E , Stephens R L , Gaynor E , Harker W G
Published: February 2017

PURPOSE

Previous reports of chemotherapy in patients with adrenal cancer have described responses to cisplatin (CDDP). Because of these reports of good results, a phase II trial that used CDDP with and without mitotane (o,p'DDD) was initiated.

PATIENTS AND METHODS

Patients with metastatic or residual adrenocortical carcinoma with objectively measurable disease or biochemical abnormalities were divided into good-risk and poor-risk categories. The latter received CDDP 100 mg/m2 intravenously, and the former received 75 mg/m2. o,p'DDD was administered at a 1,000-mg dose orally four times a day along with cortisone acetate and Florinef (fludrocortisone acetate; Bristol-Myers Squibb Co, Princeton, NJ).

RESULTS

Of a total of 42 patients entered onto the study, 37 were eligible. Twenty-nine patients received good-risk and eight received poor-risk doses of CDDP. Functioning tumors were present in 45% of patients. Objective responses were noted in 30% (11 of 37) patients (95% confidence interval, 16% to 50%). Response duration was 7.9 months, and the median time to response was 76 days. The median survival of the 37 eligible patients was 11.8 months, and a significant survival advantage was found for patients who underwent prior surgical removal of their primary tumor or bulky disease, who had a performance status of 0 or 1, or who had synchronous metastatic disease. Toxicity of the CDDP and o,p'DDD combination was moderate to severe, and the most common side effects were gastrointestinal, renal, and neurologic.

CONCLUSION

The regimen of CDDP and o,p'DDD has activity in patients with adrenocortical carcinoma; however, the toxicity of this treatment was moderate to severe.

Published: February 2017

PURPOSE

A randomized trial was conducted in patients with small-cell lung cancer (SCLC) to determine if survival can be improved by a weekly chemotherapy regimen combining various drugs.

PATIENTS AND METHODS

Two hundred twenty-three patients were randomized to receive either six courses of a multiple-drug combination (MDC) regimen (Adriamycin [ADR; doxorubicin; Farmitalia Carlo Erba, Milan, Italy] 25 mg/m2 intravenously [i.v.] on day 1; etoposide [VP16] 120 mg/m2 i.v. on day 1; cyclophosphamide [CPA] 500 mg/m2 i.v. on day 1; cisplatin 60 mg/m2 i.v. on day 8; vindesine [VDS] 3 mg/m2 i.v. on day 8; vincristine [VCR] 2 mg i.v. on day 15; methotrexate [MTX] 100 mg/m2 i.v. on day 15), or a standard chemotherapy (SC) regimen (ADR 50 mg/m2 i.v. on day 1; CPA 1 g/m2 i.v. on day 1; VP16 80 mg/m2 i.v. on days 1 to 3).

RESULTS

In 98 MDC-treated and 101 SC-treated assessable patients, we observed 69% and 62% objective responses rates, respectively. There was no significant difference in survival, with median durations and 2-year overall survival rates of 49 and 43 weeks and 8.5% and 7.9%, respectively. There was a significant increase in response rate in favor of MDC patients with limited disease (84% v 62%). Toxicity was tolerable, although SC was more hematotoxic, with 76% (v 59%) experiencing leukopenia and 17% (v 7%) experiencing thrombocytopenia (grades III and IV). If the cumulative doses received were nearly equal to the scheduled cumulative doses in both arms, the total relative dose-intensity (RDI) was significantly higher in the SC arm. The difference was due to increased treatment delays in the MDC arm.

CONCLUSION

Weekly MDC failed to improve survival rates in patients with SCLC.
Corrected QT interval prolongation in anthracycline-treated survivors of childhood cancer.
Authors: Schwartz C L , Hobbie W L , Truesdell S , Constine L C , Clark E B
Published: February 2017

PURPOSE

Comprehensive cardiac evaluations are currently recommended for all anthracycline-treated patients to detect subclinical cardiac failure. A screening test is needed that would easily and inexpensively identify patients who are at risk for late cardiac decompensation.

METHODS

We routinely reviewed the ECG and echocardiogram (ECHO) results of 52 of 56 anthracycline-treated long-term survivors of childhood cancer who had received > or = 100 mg/m2 of ANTH (ANTH = 1 mg/m2 of doxorubicin), and who were not in clinical heart failure. Exercise testing was performed in eight patients with a corrected QT interval (QTc) of > or = 0.43.

RESULTS

Zero of 15 patients (without chest radiation) who received less than 300 mg/m2 of ANTH versus six of 22 who received > or = 300 mg/m2 of ANTH had a QTc > or = 0.43 (P = .03). Three of 15 patients (with chest radiation) who received less than 300 mg/m2 of ANTH versus 12 of 22 who received > or = 300 mg/m2 of ANTH had a QTc > or = 0.43 (P = .03). For all patients (including those with chest radiotherapy), zero of 19 who received less than 300 mg/m2 of ANTH versus eight of 33 who received > or = 300 mg/m2 of ANTH had a QTc of > or = 0.45 (P = .025). Three of 19 who received less than 300 mg/m2 of ANTH versus 19 of 33 who received > or = 300 mg/m2 of ANTH had a QTc of > or = 0.43 (P = .003). One patient had decreased fractional shortening (FS) and QTc prolongation. Cardiac decompensation (with a FS of 24%) occurred with propranolol in a patient with previously normal FS but prolonged QTc. With exercise, the QTc became further prolonged in all four patients with a QTc of 0.44 to 0.46 and in two of four patients with a QTc of 0.43.

CONCLUSION

Prolongation of the QTc, a measure of myocardial repolarization, may reflect injury to myocardial cells. QTc prolongation may be predictive of an increased risk of late cardiac decompensation. If the utility of the QTc measure is confirmed, screening for evidence of myocardial damage can be easily and inexpensively performed by oncologists and primary caretakers.
Prostate-specific antigen as a pretherapy prognostic factor in patients treated with radiation therapy for clinically localized prostate cancer.

Published: February 2017

PURPOSE

This study was conducted to determine the value of prostate-specific antigen (PSA) as a pretherapy prognostic factor for localized prostate cancer treated with primary irradiation (RT).

PATIENTS AND METHODS

Between March 1987 and December 1990, 254 patients with pretherapy PSA determinations were treated for clinical stage A2 to C prostate adenocarcinoma. In conjunction with other prognostic factors, pretherapy PSA was evaluated to determine whether it had independent predictive value for disease outcome.

RESULTS

Pretherapy PSA was highly and directly correlated with clinical stage, tumor grade, and acid phosphatase level. With a median follow-up duration of 24 months, 241 patients (95%) were fully assessable for disease outcome. In these patients, PSA and tumor grade were the sole independent predictive factors for tumor relapse (ie, clinically determined and/or increasing PSA level). The combination of pretherapy PSA and tumor grade information defined groups of patients with distinctly different outcome. For patients in low- (favorable PSA and tumor grade), intermediate- (favorable PSA or tumor grade), and high- (adverse PSA and tumor grade) risk categories, the actuarial rates of survival free of tumor relapse or increasing PSA level were 94%, 77%, and 42% at 3 years, respectively (P < .0001).

CONCLUSION

Pretherapy PSA is a strongly independent prognostic factor for disease outcome following primary RT. The combination of adverse pretherapy PSA and unfavorable tumor grade identified a cohort of patients with a high risk of early treatment failure in whom combined modality therapy may be appropriately investigated.

Authors: Khayat D , Borel C , Tourani J M , Benhammouda A , Antoine E , Rixe O , Vuillemin E , Bazex P A , Thill L , Franks R
Published: February 2017

PURPOSE

To evaluate the activity and the toxicity of the combination of cisplatin (CDDP)/recombinant interleukin-2 (rIL-2) and interferon alfa-2a (IFN alpha) in disseminated malignant melanoma (DMM).

PATIENTS AND METHODS

Between December 1990 and March 1992, 39 patients with biopsy-proven metastatic malignant melanoma (MM), bidimensionally measurable lesions and an Eastern Cooperative Oncology Group (ECOG) performance status < or = 2 entered this protocol. Seventy-nine percent had received previous chemotherapy including platinum complex (15%) and alpha interferon (44%). They received CDDP (100 mg/m2 on day 0) followed by IL-2 18.10(6) IU/m2/d continuous intravenous (IV) infusion from day 3 to day 6 and from day 17 to day 21. The cycle was repeated on day 28. Subcutaneous IFN alpha 9.10(6) IU three times weekly was administered throughout the treatment period. From day 66 or 94, patients were administered a maintenance cycle with CDDP 100 mg/m2, subcutaneous IL-2 5.10(6) IU/m2/d from day 15 to day 19 and from day 22 to day 26 and IFN alpha 9.10(6) IU three times weekly repeated every 5 weeks (maximum four cycles).

RESULTS

Among 39 assessable patients, five patients achieved complete responses (CRs). Sixteen patients had partial responses (PRs). The overall objective response rate was 53.8%. The number of metastatic sites was the only response-predictive factor. Toxicity was manageable in a routine patient setting and there was no life-threatening toxicity.

CONCLUSION

These results seem to indicate a possible synergy between CDDP/rIL-2 and IFN alpha in MM.
Hepatic toxicity associated with fluorouracil plus levamisole adjuvant therapy.
Authors: Moertel C G , Fleming T R , Macdonald J S , Haller D G , Laurie J A
Published: February 2017

PURPOSE

To determine the frequency and nature of hepatic toxicity associated with fluorouracil (5-FU) plus levamisole adjuvant therapy.

PATIENTS AND METHODS

All patients had resection of stage II or stage III colon cancer and were randomized to receive observation only, levamisole alone, or 5-FU plus levamisole. Serial liver function studies were documented in 1,025 patients who did not develop recurrence during the year of therapy.

RESULTS

One hundred forty-nine (39.6%) of 376 patients treated with 5-FU plus levamisole showed laboratory abnormalities consistent with hepatic toxicity, compared with 16.3% of 251 patients treated with levamisole alone and 16.1% of 398 untreated controls. Most common was elevation of alkaline phosphatase, frequently accompanied by elevations of transaminase or serum bilirubin. Characteristically, these changes were mild, not associated with symptoms, and resolved when therapy was stopped. In some instances, they were associated with elevated carcinoembryonic antigen (CEA) tests or with fatty liver seen on computed tomographic (CT) scan or liver biopsy.

CONCLUSION

Mild and reversible hepatotoxicity is a common consequence of 5-FU plus levamisole adjuvant therapy, but this is only rarely symptomatic. However, the oncologist should be alert to this phenomenon, since the associated laboratory and imaging findings may simulate those associated with hepatic metastasis.
AMOPLACE treatment of intermediate-grade and high-grade malignant lymphoma: a Cancer and Leukemia Group B study.
Authors: Parker B A , Santarelli M , Green M R , Anderson J R , Cooper M R , Case D , Barcos M , Peterson B A , Gottlieb A J
Published: February 2017

PURPOSE

In an attempt to improve the efficacy of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy for intermediate-grade and high-grade non-Hodgkin's lymphomas, a phase II evaluation of a regimen consisting of Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), methotrexate, Oncovin (vincristine; Eli Lilly Co, Indianapolis, IN), prednisone, leucovorin, cytarabine (ara-c), cyclophosphamide, and etoposide (AMOPLACE) was conducted. This regimen includes three additional agents not found in CHOP, uses weekly doses of alternating myelosuppressive and nonmyelosuppressive drugs, and incorporates most single agents active against diffuse lymphomas.

PATIENTS AND METHODS

Ninety-one previously untreated patients were enrolled and 60 patients were confirmed eligible after central pathology review. Fifty-eight percent of patients had diffuse large-cell lymphoma (DLCL), 83% had stage III or IV disease, and 45% had B symptoms.

RESULTS

Patients were treated with six to eight cycles of AMOPLACE and analyzed for response and survival. With a median follow-up of 48 months, complete responses (CRs) were seen in 68% of all patients with failure-free survival (FFS) and overall survival (OS) estimates at 4 years of 45% and 54%. In the DLCL subset, the CR rate was 69% and FFS and OS estimates at 4 years were 49% and 60%, respectively. The major toxicity was myelosuppression, with 73% of patients having WBC nadirs less than 1,000/microL; two treatment-related deaths occurred.

CONCLUSION

We conclude that AMOPLACE is associated with CR and OS rates comparable with those of other third-generation regimens.
