One hundred sixty-seven evaluable patients with non-small-cell lung cancer were randomized to receive high-dose cisplatin and vindesine (PVD), or cisplatin and VP-16-213 (etoposide epipodophyllotoxin) (PVP), or cisplatin with VP-16-213 and vindesine (PVPVD). The patient distribution and characteristics were similar in all the treatment arms. The response rate differences (35% in PVD arm, 30% in PVP arm, and 22% in PVPVD arm) were not statistically significant (P = .33). Response durations were 43 weeks in the PVD arm, 20 weeks in the PVP arm, and 27 weeks in the PVPVD arm. Median survival was 29 weeks in the PVD and PVP arms and 28 weeks in the PVPVD arm. Median survival time of responding patients was 76 weeks in the PVD arm and 65 weeks in the PVP arm; 78% of patients were alive at 22+ to 87+ weeks follow-up in the PVPVD arm. Myelosuppression was similar in all three treatment arms. Significantly more azotemia occurred in the PVD arm than in the PVP and PVPVD arms (P = .002), and significantly more neuropathy in the PVD and PVPVD arms than in the PVP arm (P = .003 and .005). All the treatment arms have similar antitumor activity in non-small-cell lung cancer, but the PVP combination is slightly less toxic than the PVD and PVPVD treatment arms.
Late intensification in small-cell lung cancer: a phase I study of high doses of cyclophosphamide and etoposide with autologous bone marrow transplantation.
Authors: Sculier J P , Klastersky J , Stryckmans P
Published: February 2017

We conducted a late dose intensification pilot study of small-cell lung cancer (SCLC) treated with high doses of cyclophosphamide (200 mg/kg) and etoposide (1.0 to 3.5 g/m2), administered during a period of 48 hours, as well as autologous bone marrow infusion. We have been able to administer safely 3 g/m2 of etoposide with the autologous bone marrow infusion and 1.5 g/m2 without it. Limiting extrahematopoietic toxicity appeared to take the form of irreversible cardiac failure. Complete responses have been obtained with our regimen for late dose intensification, but the duration of the responses and the survival rates of the patients were poor. This suggests that late dose intensification in incomplete responders is not superior to the usually reported results obtained with standard regimens for the treatment of SCLC.
Tamoxifen flare in advanced endometrial carcinoma.
Authors: Brooks B J , Lippman M E
Published: February 2017

Tamoxifen citrate has recently been shown to be effective palliative therapy in advanced endometrial carcinoma. Flare reactions from tamoxifen are well known in treatment of metastatic breast carcinoma and are not an indication for stopping therapy. We report a patient being treated with tamoxifen for advanced endometrial cancer who developed acute abdominal pain as a manifestation of a flare reaction and the significance of this observation.
Detection of P-glycoprotein in ovarian cancer: a molecular marker associated with multidrug resistance.
Authors: Bell D R , Gerlach J H , Kartner N , Buick R N , Ling V
Published: February 2017

A multidrug resistance phenotype is frequently observed in animal and human cell lines selected for in vitro resistance to a single chemotherapeutic agent. Overexpression of a highly conserved cell-surface glycoprotein (P-glycoprotein) is consistently associated with this phenotype in these mutant lines. A monoclonal antibody against P-glycoprotein was used to examine tumor samples from five patients with advanced ovarian cancer for evidence of P-glycoprotein overexpression. High levels of P-glycoprotein were detected in samples from two patients suggesting that a multidrug resistance mutation may also occur in ovarian cancer. This finding has broad implications for the understanding of nonresponse to chemotherapy in a variety of human neoplasms, and may provide a rational explanation for failure of chemotherapy in treatment of advanced ovarian cancer.

Published: February 2017

A murine monoclonal antibody against a surface antigen of small-cell carcinoma of the lung (SM1 antibody) was investigated for its use in detecting bone marrow metastasis. Bone marrow cells of healthy volunteers and of patients with small-cell carcinoma of the lung (SCCL) were examined for reactivity with SM1 antibody and indirect immunofluorescence and the results compared to conventional histochemical staining (Wright-Giemsa stain of bone marrow aspirates and hematoxylin-eosin stains of bone marrow biopsies). No SM1 reactivity was found in marrow cells of eight healthy volunteers. Thirty-six samples from 33 patients with SCCL were examined; tumor involvement was found in 69% by SM1 antibody and in 16% by histochemical stains. All bone marrow samples from patients with SCCL that were unreactive with SM1 antibody also showed no evidence of tumor involvement by histochemical stains. Samples of 29 patients were investigated at initial staging; SM1 reactive cells were found in 50% of 16 patients with limited disease and in 77% of 13 patients with extensive disease. Overall, the proportion of patients recognized to have disseminated disease at diagnosis was increased from 45% to 72% by monoclonal antibody staining. Indirect immunofluorescence with SM1 antibody allows detection of bone marrow metastasis of SCCL that cannot be seen by conventional morphology and can identify disseminated disease in patients otherwise staged limited disease.

Published: February 2017

Improvements in therapy for childhood acute lymphoblastic leukemia (ALL) have led us to reevaluate the prognostic significance of lymphoblast characteristics at diagnosis. From application of univariate and multivariate statistical methods, we determined the relationship of five blast cell features to treatment outcome in 250 patients who were enrolled in two clinical trials at this center from May 1979 through April 1982. Karyotype ploidy, lymphoblast morphology, and immunophenotype were each significantly related to prognosis as measured by time to failure, while periodic acid-Schiff reactivity and glucocorticoid receptor number lacked prognostic implication for this patient population. In addition, clinical features of initial WBC count, age, and race were also significant independent variables in predicting treatment response. By multivariate analysis, both ploidy and morphology contributed prognostic information to a clinical model based on WBC count, age, and race. If the model was adjusted for impact of ploidy, however, French-American-British morphology no longer contributed additional prognostic information. Our findings suggest that many traditional biological features used to estimate prognosis in ALL can be discarded in favor of clinical features (leukocyte count, age, and race) and cytogenetics (ploidy) for planning of future clinical trials.

Published: February 2017

Twenty children with acute lymphoblastic leukemia who developed meningeal disease were treated with a high-dose intravenous methotrexate regimen that was designed to achieve and maintain CSF methotrexate concentrations of 10(-5) mol/L without the need for concomitant intrathecal dosing. The methotrexate was administered as a loading dose of 6,000 mg/m2 for a period of one hour followed by an infusion of 1,200 mg/m2/h for 23 hours. Leucovorin rescue was initiated 12 hours after the end of the infusion with a loading dose of 200 mg/m2 followed by 12 mg/m2 every three hours for six doses and then every six hours until the plasma methotrexate level decreased to less than 1 X 10(-7) mol/L. The mean steady-state plasma and CSF methotrexate concentrations achieved were 1.1 X 10(-3) mol/L and 3.6 X 10(-5) mol/L, respectively. All 20 patients responded to this regimen, 16/20 (80%) achieved a complete remission, and 20% obtained a partial remission. The most common toxicities encountered were transient serum transaminase and bilirubin elevations, neutropenia, and mucositis. One patient had focal seizures and transient hemiparesis but recovered completely. High-dose intravenous methotrexate is an effective treatment for the induction of remission after meningeal relapse in acute lymphoblastic leukemia.
Non-Hodgkin's lymphoma of the stomach: a prospective pilot study of surgery plus chemotherapy in early and advanced disease.
Authors: Sheridan W P , Medley G , Brodie G N
Published: February 2017

A prospective pilot study of 23 patients with non-Hodgkin's lymphoma involving the stomach was undertaken to assess the efficacy of surgical resection followed by chemotherapy with adjuvant cyclical cyclophosphamide, vincristine, and prednisolone (CVP) in early stage disease, and cyclical cyclophosphamide, vincristine, prednisolone, and doxorubicin (CHOP) in advanced disease. One of 18 evaluable patients died postoperatively; 17 of 18 completed therapy and are alive and disease-free at a median follow-up of 41 months after surgery (range, 5 to 111 months), including four patients with stage IV disease who remain in complete remission 19 to 47 months after surgery. There was one postoperative death, giving an actuarial survival rate of 94% in the study group. Three of five inoperable patients were treated with CHOP, with two achieving complete remission. Two untreated patients died. Overall actuarial disease-free survival was 82.6%. Surgical resection plus chemotherapy is capable of producing long-term remission and cure in both localized and advanced non-Hodgkin's lymphoma of the stomach. Intensive supportive care plus chemotherapy may salvage a proportion of patients with inoperable tumors.

Published: February 2017

The leukemic cells of 57 patients with adult T cell leukemia (ATL) were analyzed for their immunologic surface markers. Forty-four cases showed normal mature inducer/helper T cell phenotype (typical group: E-RFC+, Leu-1+, 2a-, 3a+ MASO36c-), but the other 13 cases showed unusual surface phenotypes (variant group) and could be subdivided into several groups (V1 to V5). Four cases had absent or low Leu-1 positivity (V1: E-RFC+, Leu-1-, 2a-, 3a+, MASO36c-), while two other cases with low Leu-1 positivity had both Leu-2a and 3a, a characteristic of cortical thymocytes, but were unreactive with MASO36c (V2: E-RFC+, Leu-1-, 2a+, 3a+, MASO36c-). Three cases lacked both Leu-2a and 3a despite having other T cell markers (V3: E-RFC+, Leu-1+, 2a-, 3a-, MASO36c-). The next three cases had low rosette-forming ability with sheep RBCs (V4: E-RFC-, Leu-1- approximately +, 2a- approximately +, 3a+, MASO36c-). Interestingly, one other case showed high reactivity against anti-Leu-7, which is believed to be one of the monoclonal antibodies directed against natural killer cells (V5: E-RFC+, Leu-1+, 2a-, 3a+, 7+, MASO36c-). Clinical and hematologic differences between the typical group and variant group were investigated, and it was found that the variant group (excluding V5) have statistically significant (P less than .002) higher serum lactic dehydrogenase (LDH) activity. The overall survival in the variant group was worse than in the typical group, but it was not quite statistically significant (P = .072). The median survival time was eight months for typical cases and only four months for variant cases; six cases died within two months. The V5 case was unusual not only because the patient's leukemic cells have Leu-7 antigen but also because she survived more than nine years after initial diagnosis. There seems to be some correlation between phenotypic diversity of ATL cells and prognosis.

Published: February 2017

The pharmacokinetics of 5-fluorouracil (5-FU) injected into a surgically isolated pelvic circuit during hyperthermic perfusion was studied in five patients with local recurrence of anorectal cancer. 5-FU doses ranged from 11 to 23 mg/kg. The geometric mean ratio of peak plasma 5-FU in the isolated to systemic circuits was 10, the ratio at the end of the 45-minute perfusion was 12.5. The mean half-life of 5-FU in the isolated circuit was 18.5 minutes. Total drug exposure for the isolated circuit was 7.8-fold greater than for the systemic compartment. These results demonstrate a large pharmacologic advantage for the use of the isolation-perfusion technique.
Postoperative radiation therapy for epithelial ovarian cancer: the curative role based on a 24-year experience.

Published: February 2017

We updated 152 cases of epithelial ovarian cancer, International Federation of Gynecology and Obstetrics (FIGO) stages I through III, treated at the Stanford Medical Center (Stanford, Calif) with irradiation as the only postoperative therapy. In 133 patients, radiation was directed only to those regions of known disease, while it was delivered to the whole abdomen and pelvis by the Martinez technique in 19 patients. Mean follow-up time was 6.8 years. The results were analyzed as freedom from relapse (FFR) at 15 years; overall, FFR constituted 44% of the patients. Statistically significant differences of FFR appeared between stages II (60%) and III (16%); among the histopathologic variants endometrioid (64%), serous papillary (45%), and undifferentiated (7%); between pathologic grades 2 (68%) and 3 (20%); between amounts of postoperative residual disease less than 2 cm (48%) and greater than 2 cm (16%); and between ages less than 40 (80%) and greater than or equal to 40 (38%). Considering all stages and grades together, FFR in the 54 cases with unfavorable residuum (greater than 2 cm) was 14%. Among the 98 with favorable residuum (none, or less than 2 cm) FFR was 62%; and 14 (39%) of the 36 relapses were in the untreated upper abdomen. Results in the favorable group support effectiveness of irradiation as postoperative therapy. These patterns of relapse suggest that whole-abdominopelvic irradiation would further increase FFR. We believe that, for favorable disease as defined such radiotherapy should be the standard for comparison.

Published: February 2017

One hundred nineteen patients were entered onto a randomized trial of the role of intravenous hyperalimentation (IVH) in patients with small-cell lung cancer. IVH was given during the first 30 days of induction chemotherapy to 54 patients. IVH did not effect any improvement in response or survival from therapy. In view of the lack of benefits from IVH, an analysis was made of the toxicities suffered by the 54 patients receiving IVH as well as any effects IVH might have made on chemotherapy-induced toxicity. Toxicities observed included mechanical difficulties with the catheter leading to temporary or permanent discontinuation of the IVH (11 patients), subclavian vein thrombosis (one patient), sepsis in nine patients v none of the 62 control patients, fluid overload (27 patients), hyponatremia (25 patients), and hyperglycemia requiring insulin (13 patients). Patients receiving IVH had higher granulocyte counts on days 14 and 21 of the first cycle of chemotherapy. Analysis shows that this difference is likely caused by fever and infection associated with IVH rather than any nutritional effect on granulopoiesis. In this population of patients, IVH had significant complications but did not ameliorate chemotherapy-induced toxicity and it did not effect any clinical benefit. Future studies of adjunctive nutritional therapy must consider the significant risk in this older population and must limit IVH volume or exclude patients with even mild compromise in cardiovascular functions. Further, any new trial must have a significant rationale for adjunctive use to justify the potential risks.
Treatment of preleukemic syndromes with continuous intravenous infusion of low-dose cytosine arabinoside.
Authors: Griffin J D , Spriggs D , Wisch J S , Kufe D W
Published: February 2017

Preleukemic syndromes compose a group of acquired bone marrow disorders characterized by dysplastic maturation of hematopoietic cells and peripheral blood cytopenias. These syndromes have been generally considered untreatable. We administered low doses of cytosine arabinoside by continuous infusion for 14 to 21 days (20 mg/m2/d) to 16 patients with preleukemia in various stages of evolution to acute leukemia. Steady state plasma cytosine arabinoside levels ranged from 41.8 to 64.2 nmol/L. Eleven patients demonstrated marked improvement in hematopoiesis and loss of transfusion requirements for periods ranging from two to 27 + months. All but one responding patient developed recurrent pancytopenia, but additional responses to low-dose cytosine arabinoside were achieved in five of five retreated patients. Median overall survival time is 12 months for the 11 responding cases, and nine months for nonresponders. The major toxicity of low-dose cytosine arabinoside is myelosuppression, and most patients required platelet transfusion support and administration of antibiotics. Chromosome analyses demonstrated evolution to a new clone of hematopoietic cells in three patients, and persistence of the same abnormal clone in another patient. These results suggest that low-dose cytosine arabinoside therapy may result in improved hematopoiesis by promoting maturation or by selecting new stem cell clones. Low-dose cytosine arabinoside therapy thus deserves further evaluation both as a single agent and in combination with other agents in the treatment of myelodysplastic syndromes.
Renal and hepatic concentrations of platinum: relationship to cisplatin time, dose, and nephrotoxicity.

Published: February 2017

Autopsy tissues were obtained from 30 patients who had received cisplatin antemortem; the tissues were assayed for platinum by flameless atomic absorption spectrometry. Patients with antemortem evidence of renal toxicity had higher renal cortical platinum concentrations than did patients without evidence of kidney damage. In addition, patients with nephrotoxicity were more likely than patients without toxicity to have renal cortical platinum concentrations that were higher than renal medullary platinum concentrations. Overall, the two variables most closely associated with an increase in serum creatinine with treatment were renal cortical platinum concentration (P less than .02) and cumulative dose of cisplatin (P less than .05). These two variables were important independently of one another. Renal cortex platinum concentrations correlated inversely with time from last treatment until death, whereas hepatic platinum concentrations did not. In contrast, hepatic platinum concentrations correlated with dose of cisplatin while renal platinum concentrations did not. Our results suggest the following: (1) cisplatin-induced renal toxicity is tissue-platinum-concentration dependent and cisplatin-dose dependent; and (2) cisplatin may be handled differently at the molecular level in liver and kidney.
A 10-year update of CHOP-Bleo in the treatment of diffuse large-cell lymphoma.

Published: February 2017

Long-term follow-up results of two studies using cyclophosphamide, doxorubicin, vincristine, and prednisone plus bleomycin (CHOP-Bleo) for the treatment of diffuse large-cell lymphoma are presented. Twenty-eight patients were treated with conventional-dose CHOP-Bleo and 36 patients with maximally tolerated doses of CHOP-Bleo. The maximal duration of follow-up was 10.5 years. The minimum follow-up was 5.7 years. Seventy-five percent of the conventional-dose group achieved a complete remission (CR) with a 10-year actuarial survival of 53% and a corresponding relapse-free survival (RFS) of 69% for CRs. Eighty-one percent of the high-dose group achieved CR, and the 10-year actuarial survival for all patients and RFS for CRs were 48% and 63%, respectively. The combined actuarial survival and RFS for both groups were 51% and 66%, respectively, at 10 years. For 11 patients with stage III disease, 91% achieved CR, 52% survived at 10 years, and the RFS was 67% for CRs. Seventy-five percent of 44 patients with stage IV disease achieved CR, 50% survived at 10 years, and the RFS was 67% for CRs. Three of the 16 relapses occurred late, between 30 to 65 months after initiation of therapy. Neuropathy occurred in 14 patients (22%). Five patients (8%) died of complications related to treatment. Five (8%) had clinically apparent, but nonfatal cardiopulmonary complications. The CHOP-Bleo regimen is an effective treatment for diffuse large-cell lymphoma, and is moderately well tolerated. The use of high-dose CHOP-Bleo for induction therapy did not result in any advantage after long-term follow-up.
The significance of bone marrow involvement in non-Hodgkin's lymphoma: the Eastern Cooperative Oncology Group experience.

Published: February 2017

Data from four clinical trials conducted by the Eastern Cooperative Oncology Group (ECOG) were used to investigate the importance of bone marrow involvement as a prognostic factor in patients with non-Hodgkin's lymphoma (NHL). A total of 502 patients, 275 with nodular, poorly differentiated lymphocytic lymphoma (NLPD) and 227 with diffuse histiocytic lymphoma (DHL) or diffuse mixed-cell lymphoma (DML), were included in this analysis. Patients were separated into four categories: stage III, stage IV with bone marrow involvement (stage IV-M), stage IV without marrow involvement (stage IV-O), and stage IV with bone marrow and other organ involvement (stage IV-OM). Among the DHL and DML patients, the incidence of marrow involvement was 23%. However, stage IV-M patients had a prognosis that is similar to stage IV-O and stage IV-OM and worse than stage III patients. In contrast, the incidence of involvement with NLPD was 59% and patients with stage IV-M had a survival not different than stage III and not worse than stage IV-O and stage IV-OM. The results suggest that the current emphasis on bone marrow biopsy(s) as a routine diagnostic staging procedure for patients with NHL should be reevaluated. The necessity for this procedure in stage III patients with NLPD is not apparent from our data. One can still justify a bone marrow biopsy in stage I and II patients and can confirm the complete clinical response when all nodes have regressed in more advanced disease.

One hundred sixty-six patients with germ-cell tumors (GCT) of the testis, retroperitoneum, and mediastinum were treated with cyclophosphamide, vinblastine, bleomycin, dactinomycin, and cisplatin (VAB-6), with and without maintenance chemotherapy. The overall complete response (CR) rate was 78%, 67% to chemotherapy alone, and 11% after chemotherapy and resection of viable residual cancer. The CR rate in all patients with seminoma was uniformly high, while the CR rate of patients with testicular nonseminomatous germ-cell tumors (79%) was superior to that of similar tumors of extragonadal origin (60%). The overall relapse rate was 12%, and was greater in tumors of extragonadal origin (21%) than in those of testicular origin (11%). Three relapses occurred after 2 years. Maintenance chemotherapy did not prolong either relapse-free or total survival. Toxicity was tolerable, and there were no treatment deaths. No Raynaud's phenomena have occurred, with a minimum duration since start of therapy of 36 months. VAB-6 is an effective chemotherapy regimen in patients with GCT with no treatment-related deaths and a majority of patients requiring only 3 months of treatment.
Cerebrospinal fluid bombesin and calcitonin in patients with central nervous system metastases from small-cell lung cancer.

Published: February 2017

To determine whether levels of mammalian bombesin (MB) or calcitonin would be useful in detecting CNS metastases in patients with small-cell lung cancer (SCLC), we measured their concentrations in the CSF of 94 patients who underwent lumbar puncture for suspected CNS involvement. The MB concentration was significantly elevated in the 51 patients with definite CNS metastases as compared with the 30 patients without apparent CNS involvement (P less than .01). This significance was due to increased levels of MB in 18 patients with meningeal carcinomatosis. Whereas CSF MB was detectable (greater than 10 fmol/mL) in only 7% of patients without apparent CNS involvement, CSF MB was detectable in 21% with parenchymal CNS metastases and in 78% of those with meningeal carcinomatosis. Interestingly, 93% of patients having MB concentrations above 20 fmol/mL had meningeal metastases. The calcitonin concentration was significantly elevated in 42 patients with CNS metastases as compared with 27 patients without CNS involvement (P less than .01). Both the 15 patients with meningeal carcinomatosis and the 27 patients with only parenchymal metastases had significantly elevated levels of CSF calcitonin as compared with those without CNS metastases. Fifty-three percent of patients with meningeal carcinomatosis and 48% with parenchymal metastases had a CSF calcitonin level above 18 fmol/mL, whereas only 7% without apparent CNS metastases exceeded this level. Sixty-seven percent of all patients with CNS metastases had increased CSF levels of one of the two hormonal markers. Thus, in SCLC patients, an elevated CSF calcitonin strongly suggested CNS metastases and an elevated MB was very suggestive of the presence of meningeal carcinomatosis. However, only the latter observation seems of clinical importance due to the difficulties in establishing this diagnosis with current diagnostic measures.
The concept of an overview of cancer clinical trials with special emphasis on early breast cancer.
Authors: Gelber R D , Goldhirsch A
Published: February 2017

Overviews are valuable investigations that require international cooperation, and can provide a useful summary of available information on a current therapeutic issue. Combining results of trials in early breast cancer is an appropriate example of such procedures. However, the advantage of bringing a large amount of information together might be overcome by the disadvantages of improper conduct and overinterpretation of the overview findings. A prospective protocol must be prepared and followed. The results must be presented in sufficient detail to allow independent conclusions to be reached. The influence of strict application of the arithmetic construct must be recognized when determining whether the conclusions about the impact of separate components of treatment are appropriate. Most importantly, the transition from scientific inquiry to the application of treatment recommendations for individual patients must still be made very cautiously. We stress the importance of the results from individual, well-conducted clinical trials for providing the critical information for guiding the choice of treatment for patients outside of trials.
Treatment of non-small-cell lung cancer.
Authors: Mulshine J L , Glatstein E , Ruckdeschel J C
Published: February 2017

The treatment of non-small-cell lung cancer (NSCLC; including squamous, large-cell anaplastic, and adenocarcinoma) is one of the most frustrating areas in oncology. With the exception of the high cure rates for surgical treatment of truly localized disease, the prognosis for patients with NSCLC is grim. Often rancorous debate has ensued about the best means of exploiting the currently available modalities of radiation therapy and chemotherapy. Recognizing that the effectiveness of the current therapeutic modalities is limited, we will review the treatment results from the past few years that help define where specific treatment options should be used or suggest areas in which to focus future trials. We will also review the implications of current findings in the cell biology of lung cancer as they pertain to the therapy of NSCLC.
Use of in vitro dose response effects to select antineoplastics for high-dose or regional administration regimens.

Published: February 2017

Several preclinical and clinical studies have documented that dose or dose intensity of chemotherapeutic agents are important factors for response of patients' tumors. This finding has prompted empiric trials of certain chemotherapeutic agents in high-dose or regional administration treatment regimens. The present study was performed to identify agents that would be particularly good candidates for high-dose or regional administration regimens against particular types of tumors. Using a human tumor cloning technique, we constructed dose in vitro response lines for ten different chemotherapeutic agents against seven different histologic types of malignancies. Slopes of the lines indicated the agents with the greatest increases of in vitro response per increment in dose of the agent. Tumors against which the agents gave the steepest dose response lines included lymphoma, head and neck cancer, ovarian cancer, and small-cell lung cancer, while the dose response lines for non-small-cell lung cancer, breast cancer, and colon cancer were quite flat. Suggestions for clinical trials based on these findings include the use of high-dose melphalan for patients with lymphoma, head and neck, and ovarian cancer; the use of mitoxantrone in high-dose regimens for patients with breast cancer; high-dose cisplatin regimens for patients with small-cell lung cancer; high-dose bleomycin regimens for patients with non-small-cell lung and head and neck cancer; and regional perfusion of liver metastases from colorectal cancer with cisplatin. Prospective testing of high-dose or regional administration regimens suggested by this new model should indicate its use for prediction of the best agent to use in high-dose regimens against a particular tumor type.
A critical appraisal of low-dose cytosine arabinoside in patients with acute non-lymphocytic leukemia and myelodysplastic syndromes.
Authors: Cheson B D , Jasperse D M , Simon R , Friedman M A
Published: February 2017

We reviewed 53 publications reporting 751 patients with hematologic malignancies treated with low doses (5 to 20 mg/m2/d) of cytosine arabinoside (LoDAC). Of 507 patients evaluable for response, complete remission (CR) rates varied from 32% for patients with primary acute non-lymphoblastic leukemia (1 degree ANLL) to 16% for patients with hematologic malignancies secondary to previous chemotherapy or following a myelodysplastic syndrome (MDS) (2 degrees ANLL), and 16% for MDS. Median duration of CR was 9.5 months for 1 degree ANLL, and 10.5 months for both 2 degrees ANLL and MDS. Based on limited available survival data, overall median survival for these groups was 9 months, 3 months, and 15 months, respectively. Only three CRs were reported of 31 evaluable patients treated for a variety of other hematologic malignancies. CR rates for patients with 1 degree ANLL greater than or equal to 50 years old was 56%, compared with 29% less than 50 years old (P = .10). While prior chemotherapy was more common in 1 degree ANLL patients less than 50 years of age (86% v 21%; P less than .001), it did not influence response rates in those greater than 50 years of age, suggesting other biases. Hematologic toxicity was mentioned in only 33 of 53 publications, affecting 254 of 289 patients (88%), with at least 15% treatment-related deaths. LoDAC hypothetically acts as a differentiating agent; however, correlative laboratory studies were rarely performed. Cytogenetic data were available for only 15%, and in vitro studies for 10% of all patients with marked discrepancies in the interpretation of results. LoDAC is clearly cytotoxic for both malignant and normal hematopoietic cells. While large numbers of patients have been reported, the lack of well-designed clinical trials prohibits definitive conclusions as to its role as a differentiating agent. Future LoDAC studies should determine optimal dose and schedule, with clinical laboratory correlates to assess differentiation. Trials in ANLL comparing LoDAC with conventional chemotherapy, and in MDS with supportive care alone, may help identify the role of LoDAC. Until appropriate indications can be identified, LoDAC should not be routinely used in clinical practice.
Diagnosing liver metastases: a Bayesian analysis.
Authors: Lind S E , Singer D E
Published: February 2017

Clinicians frequently perform tests to determine whether patients have liver metastases. Optimal use of a laboratory test requires that the clinician know the test's operating characteristics (its sensitivity and specificity) and have an estimate of the pretest probability that disease is present. We have surveyed studies that examined the value of four biochemical and three imaging tests in establishing a diagnosis of hepatic metastases in patients who underwent an invasive procedure to establish the presence or absence of disease. We have pooled the data from these studies to arrive at values for the sensitivity and specificity of each of these tests, and calculated the predictive values for these tests over a wide range of pretest probabilities of disease. Several examples illustrate how this information may be used clinically. We provide a framework for the optimal interpretation of these commonly ordered tests and indicate the data needed for their complete analysis.

Using a randomized prospective trial design, chemotherapy with 5-fluorouracil, vincristine, and mitomycin C (FOMi) was compared with cyclophosphamide, doxorubicin, and cisplatin (CAP) and with FOMi alternating with CAP (FOMi/CAP) in 452 eligible patients with metastatic large-cell undifferentiated and adenocarcinoma of the lung. Objective responses were obtained in 26%, 17%, and 22% of patients treated with FOMi, CAP, and FOMi/CAP, respectively. The median survival was similar for FOMi, CAP, and FOMi/CAP therapies (20, 24, and 23 weeks, respectively), but the overall survival (log rank test), 1-year survival, and remission duration were longer for FOMi/CAP-treated patients. Survival was significantly longer for fully ambulatory FOMi/CAP-treated patients compared with either FOMi (P = .01) or CAP (P = .04). Younger patients treated with full doses of therapy responded more often than older patients receiving reduced drug doses (26% and 11%, respectively; P = .003). A prognostic factor regression analysis of all eligible patients indicates that sex, performance status, stage, and treatment assigned were important independent variables determining survival (P less than .05). Toxicity was comparable in each treatment group.
Pancreatic carcinoma and Trousseau's syndrome: experience at a large cancer center.

It is common belief that carcinoma of the pancreas has an inherent and unique ability to induce a hypercoagulable diathesis that leads to clinically significant thrombosis. We evaluated 130 consecutive patients with adenocarcinoma of the pancreas to document the incidence and the predisposing factors related to the postulated increased association of thromboembolic disorder (TED) and pancreatic carcinoma. Only nine such patients (6.9%) demonstrated TED complications of the classical Trousseau syndrome. In these instances, the location of the tumor and its mucin-producing potential were significant predisposing factors. In our series, TED was usually associated with tumors of the body and tail, which had a greater likelihood to be mucinogenic as compared with those localized to the head of the pancreas. Routine tests for hemostasis were not helpful in predicting the development of TED except, perhaps, for decreased platelet counts. Therefore, we believe that the relationship between cancer of the pancreas and TED should be de-emphasized since it is neither unique nor especially common to pancreatic carcinoma and since it may be frequently encountered in other varieties of visceral malignancies of the cancer patient population.

Teniposide, VM-26 (Vumon), was administered in a dose of 60 mg/m2 on days 1 to 5 every third week to 36 patients with histologically confirmed small-cell lung cancer. None had previously received chemotherapy or radiotherapy. The median age was 73 years (range, 52 to 79). Thirty-three patients were evaluable; 21 of these had local disease. Five patients had bone marrow metastases, four had liver involvement, and one CNS metastases. All patients had a performance status less than or equal to 2 before the start of treatment. Thirty patients obtained a response (90%), ten of whom had a complete remission (30%). The median duration of remission was 8+ months (range, 1.1 to 17+ months), whereas the median survival was 8.7 months (range, 1.9 to 20 months). Toxicity was primarily hematologic, with leukopenia the only dose-limiting effect. Besides alopecia, all other side effects were minimal including nausea and vomiting. We find these results provocative in regard to the response rate and the duration of response obtained as well as in reference to the dismal results that prior investigations in previously treated patients have shown. These data may indicate the need for reconsideration of the usual strategy for performing phase II trials.

Twenty-nine patients were treated with 31 courses of high-dose combination cyclophosphamide, cisplatin, and carmustine (BCNU) with and without melphalan with autologous bone marrow support. Toxicity was dose related. The maximum tolerated dose for cyclophosphamide, cisplatin, and BCNU in this combination in mg/m2 was 5,625, 165, and 600, respectively. Further dose escalation was precluded by the development of multiple organ toxicity, including venoocclusive disease, refractory thrombocytopenia, and hypertension. Melphalan added to the three-drug combination produced excessive renal and gastrointestinal toxicity. Objective tumor regression occurred in 21 of 25 evaluable cases. The results suggest that selected alkylating agents can be combined in full or nearly full doses before nonmyelosuppressive dose-limiting toxicity precludes further escalation.

Thirty-three adult patients with solid tumors were treated with menogaril, a new anthracycline antibiotic. The drug was given as a two-hour infusion every 4 to 5 weeks at doses ranging from 17 to 250 mg/m2. The maximum tolerated dose was 250 mg/m2. Reversible and dose-related leukopenia was the dose-limiting toxicity. Thrombocytopenia was less frequent. Hematologic toxicity was maximal 2 weeks after treatment, and recovery usually occurred within 4 weeks. There was no dissociation between WBC and neutrophil counts, and myelosuppression did not appear to be cumulative up to 200 mg/m2. Myelosuppression was more severe for patients with heavy pretreatment and/or bone marrow involvement. Local toxicity consisting of phlebitis and/or erythema was the most common nonhematologic toxicity, especially at 250 mg/m2 (eight out of nine patients). Usually, erythema appeared within 24 hours after treatment at or near the infusion site and resolved within a few days. Occasionally, a more persistent (several weeks) orange discoloration suggesting cutaneous deposits of menogaril was observed. Nausea and vomiting were uncommon and never severe. Alopecia and mucositis were rare. Minor arrhythmias were seen in several patients during treatment, but their relationship with menogaril therapy was unclear, and in no patient did heart failure develop. Plasma concentrations were best described by a tricompartmental model with a mean terminal half-life of 29.5 hours and a mean total-body clearance of 20.2 L/h/m2. Doses of 160 and 200 mg/m2 are recommended for phase II trials in poor- and good-risk patients, respectively.

A randomized clinical trial of combination chemotherapy for patients who relapsed following primary radiation therapy for Hodgkin's disease was conducted from 1975 to 1981 by the Cancer and Leukemia Group B (CALGB). One hundred thirteen patients were prospectively randomized to receive 12 cycles of either CVPP (CCNU, vinblastine, procarbazine, and prednisone), ABOS (bleomycin, vincristine [Oncovin; Lilly, Indianapolis], doxorubicin [Adriamycin, Adria Laboratories, Columbus, Ohio], and streptozotocin), or alternating cycles of CVPP and ABOS. The median length of observation for patients in this report is 4 years. Toxicities of the three treatment programs were primarily hematologic. Frequencies of complete response were 72% for CVPP, 70% for ABOS, and 82% for CVPP/ABOS (P = .37). Females and patients who had nodular sclerosing disease at initial diagnosis had significantly higher complete response rates. The 5-year disease-free survival for the complete responders was 55%; the 5-year overall survival was 60%. There were no significant differences among the treatments on disease-free survival (P = .78) or overall survival (P = .18). Age under 40 years was the only significant positive prognostic factor for disease-free survival (P = .095) and overall survival (P = .003). This study demonstrates no statistically significant advantage for alternating cycles of combination chemotherapy in affecting complete response frequency, disease-free survival, or overall survival as compared with therapy with CVPP or ABOS alone. However, the power to detect differences in these outcome parameters is somewhat limited by the sample sizes.(ABSTRACT TRUNCATED AT 250 WORDS)
Antiemetics in children receiving cancer chemotherapy: a double-blind prospective randomized study comparing metoclopramide with chlorpromazine.
Authors: Graham-Pole J , Weare J , Engel S , Gardner R , Mehta P , Gross S
Published: February 2017

This is the first prospective randomized study comparing commonly used antiemetics in children receiving cancer chemotherapy. We compared metoclopramide (MCP) with chlorpromazine (CLP), both administered in conventional doses, in 50 cancer patients aged 6 to 18 years who were receiving emetic chemotherapy. CLP proved significantly better than MCP in reducing both the frequency of vomiting (P less than .05) and the duration of nausea and vomiting (P less than .025). Extrapyramidal reactions (EPRs) were more common in MCP-treated patients. We conclude that, in the standard doses used, CLP is a better overall antiemetic than MCP for children receiving intensive chemotherapy. However, further prospective pediatric studies of antiemetic combinations are needed.

Two hundred fourteen patients with disseminated non-seminomatous testicular cancer were randomized to receive induction chemotherapy with cisplatin, vinblastine, and bleomycin (PVB). The randomization was for vinblastine 0.4 mg/kg/cycle or 0.3 mg/kg/cycle. The complete response (CR) rates to both regimens were identical: 68% and 71%, respectively. In addition, there was no significant difference in disease-free and overall survival. There was a significant decrease in the incidence of WBC nadirs below 1,000/microL: 29% and 13%, respectively (P = .01). Of the non-hematologic toxicities, there was a significant reduction in the incidence of mucositis: 53% and 37%, respectively (P = .006). The major prognostic factor was tumor volume. This study confirms that vinblastine 0.3 mg/kg/cycle in PVB chemotherapy is as effective and less toxic than vinblastine 0.4 mg/kg/cycle.

To determine the role of chemotherapy in the multidisciplinary treatment of patients with osteosarcoma, a randomized prospective trial of postoperative adjuvant chemotherapy was begun in 1981. Fifty-nine patients with nonmetastatic classic intramedullary osteosarcoma were randomized; 32 received postoperative adjuvant chemotherapy consisting of high-dose methotrexate, Adriamycin (Adria Laboratories, Columbus, OH), and BCD (bleomycin, cytoxan, actinomycin D), and 27 patients received no adjuvant chemotherapy. At a median follow-up of 2 years, there was a statistically significant improvement in both disease-free and overall survival in those who received adjuvant chemotherapy. In addition, there was no difference in the less than 20% disease-free or overall survival of patients treated in the 1970s who did not receive chemotherapy, as compared with the concurrent nontreatment controls. Therefore, with identical staging procedures, uniform surgical management, and standard pathologic evaluation, postoperative adjuvant chemotherapy definitely improves disease-free and overall survival in patients with osteosarcoma.
