PURPOSE

The identification of immunophenotypic aberrancies through multiparametric flow cytometry makes the differentiation between normal and leukemic cells relatively simple and quick, and is therefore an attractive method for the investigation of minimal residual disease (MRD). In this report, we have analyzed the impact on relapse and relapse-free survival (RFS) of detecting immunophenotypical aberrant cells in acute lymphoblastic leukemia (ALL) patients in cytomorphologic complete remission (CR).

MATERIALS AND METHODS

Two hundred eleven bone marrow (BM) samples from 53 consecutive ALL (37 precursor B-ALL and 16 T-ALL) patients were analyzed. The only selection criteria were to have at least one aberrant immunophenotypic feature at diagosis and to have achieved cytomorphologic CR after induction therapy. For MRD detection, all follow-up samples were analyzed with triple labelings using a two-step acquisition procedure, in which 106 cells were screened for the possible persistence of residual leukemic cells with the same phenotypic aberrancy as that identified diagnosis.

RESULTS

Patients who displayed a gradual increase in MRD levels showed a higher relapse rate (90% v22%; P < .00001) and shorter median RFS (12 months v not reached; P < .0001) than those with stable or decreasing MRD levels. This adverse prognostic influence also was observed when children and adults, as well as B-ALL and T-ALL patients, were analyzed separately. An MRD level > or = or greater than 10(-3) discriminated two risk groups of ALL patients with significantly different relapse rates and RFS at all treatment phases (end of induction, consolidation, maintenance, and out of treatment).

CONCLUSION

Multiparametric flow cytometry of MRD in ALL patients is a valuable tool for relapse prediction and for the identification of a cohort of patients with very poor prognosis.

Published: February 2017

PURPOSE

We evaluated the response to Temodal (Schering-Plough Research Institute, Kenilworth, NJ) of patients with newly diagnosed malignant glioma, as well as the predictive value of quantifying tumor DNA mismatch repair activity and O6-alkylguanine-DNA alkyltransferase (AGT).

PATIENTS AND METHODS

Thirty-three patients with newly diagnosed glioblastoma multiforme (GBM) and five patients with newly diagnosed anaplastic astrocytoma (AA) were treated with Temodal at a starting dose of 200 mg/m2 daily for 5 consecutive days with repeat dosing every 28 days after the first daily dose. Immunochemistry for the detection of the human DNA mismatch repair proteins MSH2 and MLH1 and the DNA repair protein AGT was performed with monoclonal antibodies and characterized with respect to percent positive staining.

RESULTS

Of the 33 patients with GBM, complete responses (CRs) occurred in three patients, partial responses (PRs) occurred in 14 patients, stable disease (SD) was seen in four patients, and 12 patients developed progressive disease (PD). Toxicity included infrequent grades 3 and 4 myelosuppression, constipation, nausea, and headache. Thirty tumors showed greater than 60% cells that stained for MSH2 and MLH1, with three CRs, 12 PRs, three SDs, and 12 PDs. Eight tumors showed 60% or less cells that stained with antibodies to MSH2 and/or MLH1, with 3 PRs, 3 SDs, and 2 PDs. Eleven tumors showed 20% or greater cells that stained with an antibody to AGT, with 1 PR, 2 SDs, and 8 PDs. Twenty-five tumors showed less than 20% cells that stained for AGT, with 3 CRs, 12 PRs, 4 SDs, and 6 PDs.

CONCLUSION

These results suggest that Temodal has activity against newly diagnosed GBM and AA and warrants continued evaluation of this agent. Furthermore, pretherapy analysis of tumor DNA mismatch repair and, particularly, AGT protein expression may identify patients in whom tumors are resistant to Temodal.

Published: February 2017

PURPOSE

In vitro synergy between cisplatin and irinotecan (CPT-11) has been reported. We designed a combination schedule of these agents to maximize the potential for synergistic interaction.

PATIENTS AND METHODS

To maximize the opportunity for synergy, we divided the cisplatin into four consecutive weekly treatments, followed by a 2-week rest. Each dose of cisplatin was immediately followed by a dose of irinotecan. The dose of cisplatin was fixed at 30 mg/m2/wk. The initial irinotecan dose was 50 mg/m2/wk and this was escalated by 30% increments in successive cohorts of three to six patients to establish the maximum-tolerated dose (MTD). Pharmacokinetics of irinotecan and its metabolites, SN-38 and SN-38 glucuronide (SN-38G), were analyzed.

RESULTS

Of 35 patients with solid tumors enrolled onto this trial, 30 were assessable for toxicity and response. The MTD for this regimen was 30 mg/m2/wk of cisplatin plus 50 mg/m2/wk of irinotecan in previously treated patients and 30 mg/m2/wk of cisplatin plus 65 mg/m2/wk of irinotecan in chemotherapy-naive patients. Neutropenia was the dose-limiting toxicity (DLT) encountered in this trial. Diarrhea was infrequent and rarely dose-limiting. Seven of 30 assessable patients achieved a partial response. No alteration in irinotecan, SN-38, or SN-38G pharmacokinetics resulted from the administration of cisplatin with irinotecan.

CONCLUSION

The administration of cisplatin and irinotecan on this weekly schedule provides a practical and well-tolerated regimen that has the potential to maximize any clinical synergy between the two agents. Evidence of substantial clinical activity was seen in this phase I study.
Survival of BRCA1 breast and ovarian cancer patients: a population-based study from southern Sweden.
Authors: Jóhannsson O T , Ranstam J , Borg A , Olsson H
Published: February 2017

PURPOSE

Recent studies indicate that BRCA1 breast and ovarian tumors may have an advantageous survival. In this population-based study, the survival of carriers of a mutated BRCA1 gene was investigated.

PATIENTS AND METHODS

The survival of 71 BRCA1-associated cancer patients (33 breast cancer, seven breast and ovarian cancer, and 31 ovarian cancer patients from 21 families with BRCA1 germline mutations) diagnosed after 1958 was compared with that of a population-based comparison group that consisted of all other invasive breast (n = 28,281) and ovarian (n = 7,011) cancers diagnosed during 1958 to 1995, as well as an age- and stage-matched control group.

RESULTS

No apparent survival advantage was found for BRCA1-associated breast cancers upon direct comparison. After adjustment for age and calendar year of diagnosis, survival was equal to or worse than that of the comparison group (hazards ratio [HR], 1.5; 95% confidence interval [CI], 0.9 to 2.4). In comparison with an age- and stage-matched control group, survival again appeared equal or worse (HR, 1.5; 95% CI, 0.6 to 3.7). For BRCA1-associated ovarian cancers, an initial survival advantage was noted that disappeared with time. Due to this time dependency, multivariate analyses cannot adequately be analyzed. Compared with the age- and stage-matched control group, survival again appeared equal or worse (HR, 1.2; 95% CI, 0.5 to 2.8).

CONCLUSION

The results suggest that survival for carriers of a BRCA1 mutation may be similar, or worse than, that for breast and ovarian cancer in general. This finding is in accordance with the adverse histopathologic features observed in BRCA1 tumors and underlines the need for surveillance in families that carry a BRCA1 mutation.
Lumpectomy and radiation therapy for the treatment of intraductal breast cancer: findings from National Surgical Adjuvant Breast and Bowel Project B-17.

Published: February 2017

PURPOSE

In 1993, findings from a National Surgical Adjuvant Breast and Bowel Project (NSABP) trial to evaluate the worth of radiation therapy after lumpectomy concluded that the combination was more beneficial than lumpectomy alone for localized intraductal carcinoma-in-situ (DCIS). This report extends those findings.

PATIENTS AND METHODS

Women (N = 818) with localized DCIS were randomly assigned to lumpectomy or lumpectomy plus radiation (50 Gy). Tissue was removed so that resected specimen margins were histologically tumor-free. Mean follow-up time was 90 months (range, 67 to 130). Size and method of tumor detection were determined by central clinical, mammographic, and pathologic assessment. Life-table estimates of event-free survival and survival, average annual rates of occurrence for specific events, relative risks for event-specific end points, and cumulative probability of specific events comprising event-free survival are presented.

RESULTS

The benefit of lumpectomy plus radiation was virtually unchanged between 5 and 8 years of follow-up and was due to a reduction in invasive and noninvasive ipsilateral breast tumors (IBTs). Incidence of locoregional and distant events remained similar in both treatment groups; deaths were only infrequently related to breast cancer. Incidence of noninvasive IBT was reduced from 13.4% to 8.2% (P = .007), and of invasive IBT, from 13.4% to 3.9% (P < .0001). All cohorts benefited from radiation regardless of clinical or mammographic tumor characteristics.

CONCLUSION

Through 8 years of follow-up, our findings continue to indicate that lumpectomy plus radiation is more beneficial than lumpectomy alone for women with localized, mammographically detected DCIS. When evaluated according to the mammographic characteristics of their DCIS, all groups benefited from radiation.
Randomized trial of r-metHu granulocyte colony-stimulating factor in an intensive treatment for T-cell leukemia and advanced-stage lymphoblastic lymphoma of childhood: a Pediatric Oncology Group pilot study.
Authors: Laver J , Amylon M , Desai S , Link M , Schwenn M , Mahmoud H , Shuster J
Published: February 2017

PURPOSE

Contemporary chemotherapy has significantly improved the event-free survival (EFS) among patients with T-cell disease. However, myelosuppression has been a significant adverse effect of this approach. In this study, we assessed the impact of r-metHu granulocyte colony-stimulating factor (G-CSF) on the period of neutropenia, number of days of hospitalization, and delays in subsequent administration of chemotherapy in a cohort of patients with T-cell leukemia (T-ALL) or advanced stage lymphoblastic lymphoma (ASLL).

PATIENTS AND METHODS

This open-label, randomized trial incorporated r-metHuG-CSF into the induction and two consecutive continuation-therapy cycles of our intensive program for T-cell malignancies. In the induction phase, r-metHuG-CSF was given after two different combinations of chemotherapy, one of which included vincristine, prednisone, cyclophosphamide, and adriamycin and the other a continuous infusion of high-dose ara-C and L-asparaginase. In the two continuation-therapy cycles, r-metHuG-CSF was given following the combination of vincristine, adriamycin, prednisone, and 6-mercaptopurine (MP) and after continuous infusion of high-dose cytarabine (ara-C).

RESULTS

Fifty-six patients with T-ALL and 33 with ASLL were enrolled onto study from April 1994 to December 1995. Our data show no significant difference in number of days of absolute neutrophil count (ANC) less than 500/microL, hospitalizations, or delays in therapy in the induction phase. However, in the continuation-therapy phase the number of days of ANC less than 500/microL was significantly shorter (P = .017) on the G-CSF-arm without significantly affecting the number of days of hospitalizations or delays in therapy.

CONCLUSION

r-metHuG-CSF did not significantly affect the period of neutropenia, hospitalization, or delays in therapy in the induction phase, whereas in the two cycles of continuation therapy, it significantly shortened the period of neutropenia.
Error rates in clinical radiotherapy.
Authors: Macklis R M , Meier T , Weinhous M S
Published: February 2017

PURPOSE

Error rates in clinical oncology are undergoing increasing scrutiny. The purpose of this study was to understand error frequency, error patterns, underlying causal links, consequences, and possible prevention strategies in clinical radiotherapy.

PATIENTS AND METHODS

Treatment information, self-reported error documentation, and retrospective analyses of electronic treatment verification transcripts for 1,925 consecutive patients treated with a total of 93,332 individual radiotherapy fields were reviewed and analyzed.

RESULTS

A total of 59 separate errors that affected 168 individual treatment fields were detected, which yielded a crude radiation delivery error rate of 0.18%. All 59 errors were judged to be level I (negligible chance of adverse medical outcome) with the most common error category being a minor treatment field block misplacement. A comprehensive quality assurance program and an electronic record-and-verify linear accelerator interlock system seem to have prevented the occurrence of many additional errors. However, nine of the 59 errors were directly related to the use of this system and generally involved the transposition of similar numbers within series of treatment coordinate data-sets. Overall, radiotherapy error rates favorably compare with reported error rates for pharmaceutical administration in large tertiary care hospitals.

CONCLUSION

When modern automated error-minimization methods are used along with nonpunitive error reporting systems, clinical radiotherapy seems to be highly safe. Formal error analysis studies may allow the rational design of prevention strategies that are attuned to the frequency, seriousness, and antecedent causes of many classes of potential radiotherapy errors.
Phase II study of carmustine, dacarbazine, cisplatin, and tamoxifen in advanced melanoma: a Southwest Oncology Group study.
Authors: Margolin K A , Liu P Y , Flaherty L E , Sosman J A , Walker M J , Smith J W , Fletcher W S , Weiss G R , Unger J M , Sondak V K
Published: February 2017

PURPOSE

The combination of carmustine (BCNU), dacarbazine (DTIC), cisplatin (DDP), and tamoxifen (Tam) has been reported in small series to provide a response rate of 50%, but with significant myelosuppression and risk of thromboembolic complications. We performed this phase II study to assess the antitumor activity and important toxicities of this combination in the cooperative group setting.

PATIENTS AND METHODS

Seventy-nine eligible patients were treated with BCNU 150 mg/m2/d, every 6 weeks, DTIC 220 mg/m2/d on days 1 to 3 every 3 weeks, DDP 25 mg/m2/d on days 1 to 3 every 3 weeks, and Tam 20 mg orally daily throughout treatment. Treatment cycles were repeated every 6 weeks in responding or stable patients for a maximum duration of 1 year.

RESULTS

Twelve objective responses were achieved (response rate 15%, 95% confidence interval 8%-25%). Five responses were complete (CR) and seven were partial (PR). The median response duration was 8+ (range, 4-19+) months, (16+ [4-19+] for CR and 8+ [4-11] for PR), and the median survival of the entire group was 9 months. The toxicities were predominantly neutropenia and thrombocytopenia. Four patients developed thromboembolic events. Two patients died while on protocol therapy, one with complications of neutropenia, and the other with disease progression.

CONCLUSION

The activity of this regimen is in the range reported for single agents or DTIC plus DDP, and the addition of BCNU and Tam appears to increase toxicity. We do not recommend this combination for routine treatment of advanced melanoma or as the control arm in randomized studies of combination therapy.

Published: February 2017

PURPOSE

To determine the effect of r-metHu granulocyte colony-stimulating factor (G-CSF) on the proportion of patients with metastatic poor-prognosis malignant germ cell tumors who receive full dose-intensity combination chemotherapy.

PATIENTS AND METHODS

In a phase III study patients received six cycles of BEP/EP (etoposide, and cisplatin, plus or minus bleomycin) or six cycles of BOP/VIP-B (bleomycin, vincristine, cisplatin/etoposide, ifosfamide, cisplatin, bleomycin). A subset were secondarily randomized to receive or not receive filgrastim. Filgrastim 5 microg/kg/day was administered subcutaneously on days 3 through 9 after each BOP and on days 6 through 19 after each VIP, BEP, or EP cycle.

RESULTS

Eighty-five percent of 120 eligible patients randomized to filgrastim received at least six chemotherapy cycles compared with 70% of 130 patients randomized to not receive filgrastim (VCP = .003). Patients in the filgrastim-arm achieved significantly higher dose-intensities. Neutropenic fever occurred in 25 of 128 filgrastim-patients and in 38 of 129 non-filgrastim-patients (P = .052). Twelve and three toxic deaths occurred in the non-filgrastim- and filgrastim-arms, respectively. Nine of the 12 toxic deaths and all of the three toxic deaths were associated with febrile grade 4 neutropenia. Failure-free and overall survival were similar in both arms.

CONCLUSION

During combination chemotherapy in patients with malignant germ cell tumors, the routine use of filgrastim significantly improved the delivery of the planned treatment schedule without effect on failure-free or overall survival. The use of filgrastim was associated with a clinically important reduction in the number of toxic deaths, confined to the experimental intensified-chemotherapy schedule. This study does not support the routine use of filgrastim during standard chemotherapy with BEP.
Outcome after invasive local recurrence in patients with ductal carcinoma in situ of the breast.
Authors: Silverstein M J , Lagios M D , Martino S , Lewinsky B S , Craig P H , Beron P J , Gamagami P , Waisman J R
Published: February 2017

PURPOSE

To detail the outcome, in terms of local recurrence, local invasive recurrence, distant recurrence, and breast cancer mortality for patients previously treated for ductal carcinoma in situ (DCIS).

PATIENTS AND METHODS

Clinical, pathologic, and outcome data were collected prospectively for 707 patients with DCIS accrued from 1972 through June 1997.

RESULTS

There were 74 local recurrences; 39 were noninvasive (DCIS) and 35 were invasive. Fifty-one percent of patients with invasive recurrences presented with stage 1 disease; the remainder presented with more advanced disease. Invasive local recurrence after mastectomy was a rare event that occurred in 0.8% of patients. Invasive recurrence after breast preservation was more common and occurred in 7.4% of patients. The 8-year probability of breast cancer mortality after breast preservation was 2.1%, a number that is likely to increase with longer follow-up. The 8-year breast cancer-specific mortality and distant-disease probability for the subgroup of 74 patients with locally recurrent disease was 8.8% and 20.8%, respectively. If only the 35 invasive recurrences are considered as events, the 8-year breast cancer-specific mortality and distant-disease probability was 14.4% and 27.1%, respectively.

CONCLUSION

Invasive local recurrence after breast-preservation treatment for patients with DCIS is a serious event that converts patients with previous stage 0 disease to patients with disease that ranges from stage I to stage IV. These results, however, indicate that most DCIS patients with local recurrence can be salvaged.
Competitive CBFbeta/MYH11 reverse-transcriptase polymerase chain reaction for quantitative assessment of minimal residual disease during postremission therapy in acute myeloid leukemia with inversion(16): a pilot study.

Published: February 2017

PURPOSE

(1) Quantification of minimal residual disease (MRD) by competitive CBFbeta/MYH11 reverse-transcriptase polymerase chain reaction (RT-PCR) in patients with acute myeloid leukemia (AML) and inversion(16) [inv(16)] during postremission therapy, (2) comparison of this method with conventional two-step RT-PCR, and (3) evaluation of a potential prognostic value.

PATIENTS AND METHODS

MRD of six consecutive adult patients with AML and inv(16)(p13;q22) or t(16;16)(p13;q22) who entered complete remission (CR) was monitored by competitive CBFbeta/MYH11 RT-PCR in their bone marrow (BM) during postremission therapy with high-dose cytarabine (HiDAC) or after BM transplantation with a matched unrelated-donor marrow (MUD-BMT) during an observation period of 4.5 to 27 months after initiation of treatment.

RESULTS

Competitive PCR showed a gradual decline by at least 4 orders of magnitude after 7 to 9 months in patients in continuous CR (CCR), while one patient who relapsed after 13.5 months only achieved a reduction by 2 orders of magnitude at the end of consolidation therapy. A rapid decrease below the detection limit was observed within 1 month in two patients after MUD-BMT. A temporary reappearance of molecular MRD was observed in these patients during immunosuppression for graft-versus-host disease (GvHD). After reduction of immunosuppression, the level of MRD dropped again below the PCR detection limit. Molecular monitoring by conventional two-step RT-PCR yielded comparable results only when multiple assays per time point were performed, while single-assay RT-PCR gave misleading results.

CONCLUSION

Competitive RT-PCR is a valuable tool for molecular monitoring during postremission chemotherapy, as well as after BMT.
Role of interferon alfa-2b in the induction and maintenance treatment of low-grade non-Hodgkin's lymphoma: results from a prospective, multicenter trial with double randomization.

Published: February 2017

PURPOSE

To evaluate the effectiveness of adding interferon (IFN) alfa-2b to chemotherapy in the induction treatment of low-grade non-Hodgkin's lymphoma (NHL), and to assess the role of maintenance IFN.

PATIENTS AND METHODS

A multicenter, two-phase controlled trial with double randomization was conducted in 155 patients with low-grade NHL. In the first randomization, 78 patients received cyclophosphamide, vincristine, and prednisone (CVP) and IFN, 3 MU/m2 three times a week for 3 months, and 77 patients received CVP alone. Responding patients were randomized to receive IFN for 1 year versus observation.

RESULTS

Of 144 assessable patients, 73 received CVP + IFN and 71 received CVP. Responses were similar: CVP + IFN 79% versus CVP 76% (P = .62). The number of patients who did not complete the treatment was higher in the CVP + IFN group than in the CVP group (18% v 4%; P = .009), although the received dose-intensity of chemotherapy was comparable. Duration of response and progression-free survival (PFS) were significantly higher in the CVP + IFN group than in the CVP group (P = .0004). However, we observed no differences in overall survival (OS) (P = .30), with a median follow-up for the surviving patients of 3 years. Grade 3/4 granulocytopenia was the most frequent toxicity and was similar in both groups (33% v32%). Eighty-three (74%) of the 112 responding patients were randomized to maintenance IFN or observation. The duration of response was similar between 42 patients that received IFN compared with 41 control patients (P = .83), independently of treatment previously administered.

CONCLUSION

Adding IFN alfa-2b to induction CVP in low-grade NHL did not induce a higher response rate, but it significantly increased the duration of the responses. We found significant differences in PFS that favored the patients who received CVP + IFN, but not in OS. To date, no additional benefit has been seen from the administration of IFN for maintenance.
Ascitic interleukin-12 is an independent prognostic factor in ovarian cancer.
Authors: Zeimet A G , Widschwendter M , Knabbe C , Fuchs D , Herold M , Müller-Holzner E , Daxenbichler G , Offner F A , Dapunt O , Marth C
Published: February 2017

PURPOSE

The clinical impact of endogenous cytokines supplied with deterministic properties in the generation of either T helper (Th)1 -type or Th2-type immune response was investigated in patients with ovarian cancer. Whereas interleukin (IL)- 12 initiates the differentiation of naive Th0 cells toward Th1 phenotype, IL-4 and IL-10 mediate the development of Th2-type immunity.

PATIENTS AND METHODS

Cytokines were determined before treatment by means of enzyme-linked immunosorbent assay (ELISA) in ascites fluid and serum of 76 patients with ovarian cancer. Cytokine levels were compared with each other and with standard clinicopathologic parameters. A stepwise logistic regression was calculated to rule out interdependence in the associations of the various variables. Survival analyses were performed with the Kaplan-Meier method and differences in survival were examined according to Mantel and Breslow. Cox proportional hazards analysis was used to identify independent prognostic factors.

RESULTS

Whereas IL-10 and IL-12 were detectable in all ascites-fluid samples, IL-4 was measurable in only 43% of the specimens. With the exception of neopterin, macrophage colony-stimulating factor (M-CSF), and IL-4, determined cytokine levels were significantly elevated in ascites fluid compared with serum (P < .01). In univariate analyses, high ascitic-fluid concentrations of either neopterin, tumor necrosis factor-alpha (TNF-alpha), or IL-12 were associated with poor disease-free (P < .005) and overall (P < .01) survival. Multivariate Cox regression analysis showed ascitic-fluid IL-12 levels to be the only immunologic variable that retained independent prognostic significance (P < .03 for disease-free and P < .01 for overall survival), together with residual disease, Fédération Internationale de Gynécologie et d'Obstétrique (FIGO)-stage, and patient age.

CONCLUSION

In ovarian cancer, high ascitic-fluid IL-12 levels, which may indicate a local Th1-generated immune response, are associated with disease progression.

Phase II trial of paclitaxel and topotecan with granulocyte colony-stimulating factor support in stage IV breast cancer.
Authors: Fleming G F , Kugler J W , Hoffman P C , Ansari R , Bitran J D , Klepsch A , Malone D , Fasanmade A A , Ratain M J , Vokes E E
Published: February 2017

PURPOSE

This multicenter phase II trial investigated the efficacy and safety of a combination of paclitaxel and topotecan in patients with pretreated metastatic breast cancer. Plasma levels of paclitaxel and topotecan were obtained during cycle 1 to correlate pharmacokinetic parameters with toxicity.

PATIENTS AND METHODS

Paclitaxel was administered intravenously (i.v.) at 230 mg/m2 over 3 hours on day 1 followed by topotecan 1.0 mg/m2 i.v. over 30 minutes on days 1 to 5. Patients received an abbreviated premedication regimen that consisted of ranitidine 50 mg, diphenhydramine 50 mg, and a single 20-mg dose of dexamethasone, all administered i.v. 30 minutes before paclitaxel. Granulocyte colony-stimulating factor (GCSF) was administered at 5 micrograms/kg/d subcutaneously starting on day 6 and continuing until the absolute granulocyte count (AGC) was greater than 10,000/microL. Plasma paclitaxel and topotecan concentrations were assessed during the first cycle using limited-sampling strategies.

RESULTS

Seventeen patients were treated. The majority had visceral metastases. Four patients experienced neutropenic fever and one had mild bronchospasm. Only one partial response (PR) was observed. Nadir AGC correlated strongly with both duration of paclitaxel levels greater than 0.05 mumol/L and maximum concentration (Cmax) of paclitaxel.

CONCLUSION

This regimen does not produce a response rate superior to that expected with single-agent paclitaxel at doses that do not require growth factor support.
Risk factors for treatment-related death in elderly patients with aggressive non-Hodgkin's lymphoma: results of a multivariate analysis.

Published: February 2017

PURPOSE

It has been suggested that age is associated with chemotherapy-related death in patients with non-Hodgkin's lymphoma (NHL) treated with doxorubicin-containing chemotherapy. The purpose of this study was to evaluate the relative influence of increasing age and other clinical parameters on the occurrence of treatment-related death in elderly patients with intermediate- or high-grade NHL treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy.

METHODS

A retrospective study of patients 60 years of age or older with intermediate- or high-grade NHL treated with CHOP chemotherapy in a single cancer center. The following variables were recorded: age (60 to 69, 70 to 79, and 80 to 94 years), histology (Working Formulation [WF] D, E, F, G, and H), Ann Arbor stage, B symptoms, extranodal involvement, bulky disease (> 7 cm), performance status (Eastern Cooperative Oncology Group [ECOG] scale), International Prognostic Index (IPI score), serum lactate dehydrogenase (LDH) level and doxorubicin relative dose-intensity (RDI). The relationship between these features and treatment-related death was assessed in univariate and multivariate logistic regression analysis.

RESULTS

From 1982 to 1991, 267 consecutive patients were treated. Median age was 70 years (range, 60 to 94 years). There were 35 toxic deaths. Sixty-three percent of the deaths occurred after the first cycle. Infection accounted for 82% of the toxic deaths. In the univariate analysis, the features associated with an increased risk of toxic death were ECOG performance status 2 to 4 (relative risk [RR], 7.82), B symptoms (RR, 3.38), diffuse large-cell histology (RR, 3.06), bulky disease (RR, 2.58), serum levels of LDH (RR, 2.53), and IPI score (RR, 2.46). The age groups did not show significance. In the regression model, performance status 2 to 4 was the only independent predictor of treatment-related death (RR, 3.52; 95% confidence interval [CI], 2.98 to 4.06).

CONCLUSION

Our results show that in elderly patients with NHL treated with doxorubicin-based chemotherapy the risk for treatment-related death is associated with poor performance status rather than with increasing chronologic age.

PURPOSE

To compare two cisplatin based chemotherapy schedules in patients with advanced non-small-cell lung cancer (NSCLC).

PATIENTS AND METHODS

A total of 332 patients with advanced NSCLC were randomized to receive cisplatin 80 mg/m2 on day 1 either in combination with teniposide 100 mg/m2 on days 1, 3, and 5 (arm A) or paclitaxel 175 mg/m2 by 3-hour infusion on day 1 (arm B); cycles were repeated every 3 weeks.

RESULTS

Fifteen patients were ineligible; patient characteristics were well balanced between the two arms: 71% were male, 71% had less than 5% weight loss, 89% had a World Health Organization (WHO) performance status of 0 to 1, 51% had adenocarcinoma, and 61% had stage IV disease. Hematologic toxicity was significantly more severe in arm A (leukopenia, neutropenia, and thrombocytopenia grade 3 or 4: 66% v 19%, 83% v 55%, 36% v 2% in arms A and B, respectively), which resulted in more febrile neutropenia (27% v 3% in arms A and B, respectively), dose reductions, and treatment delays. There were a total of nine toxic deaths, six due to neutropenic sepsis: five in arm A and one in arm B. In contrast, arthralgia/myalgia (grade 2 or 3, 4% v 17%), peripheral neurotoxicity (grade 2 or 3, 6% v 29%), and hypersensitivity reactions (1% v 7%, all grades) were significantly more frequent in arm B. The frequency and severity of other toxicities were comparable between the two arms. Responses were one complete and 44 partial on arm A (28%) and two complete and 61 partial (41%) on arm B (P = .018). There was no significant difference in survival, with median and 1-year survivals 9.9 versus 9.7 months and 41% versus 43%, respectively in arm A and B. Progression-free survival was 4.9 and 5.4 months in arm A and B, respectively. Selected centers participated in a quality-of-life (QoL) assessment, which was performed by the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and LC-13 administered at baseline and every 6 weeks thereafter. Arm B achieved a better score at week 6 for emotional, cognitive and social functioning, global health status, fatigue, and appetite loss, which was lost at 12 weeks. In conclusion, arm B appears superior to arm A with regard to response rate, side effects, and QoL.

CONCLUSION

Although survival was not improved, arm B offers a better palliation for advanced NSCLC patients than arm A.

PURPOSE

To evaluate the trade-off of toxicity versus improved clinical outcome with interferon alfa-2b (IFN) administered concomitantly with a doxorubicin-containing regimen for the treatment of advanced follicular lymphoma.

PATIENTS AND METHODS

A quality-of-life-adjusted survival analysis (Quality-Adjusted Time Without Symptoms or Toxicity [Q-TWiST]) was applied to the Groupe d'Etude des Lymphomes Folliculaires (GELF) trial 86, which compared a regimen of cyclophosphamide, doxorubicin, teniposide, and prednisone (CHVP) versus CHVP plus IFN in 242 patients with confirmed follicular lymphoma. CHVP was administered monthly for 6 months then every other month for 12 months. The IFN dosage was 5 x 10(6) U three times weekly for 18 months.

RESULTS

After a median follow-up duration of 72 months, the IFN group gained a mean of 12.3 months of progression-free survival (PFS) and 7.4 months of overall survival (OS), but also experienced additional time with grade 3 or worse toxicity compared with the CHVP group. Sensitivity analysis demonstrated that CHVP plus IFN provided a greater amount of quality-adjusted survival regardless of the relative quality-of-life valuations placed on time with toxicity due to CVHP alone, time with toxicity due to CHVP plus IFN, and time following disease progression. This gain was significant (P < .05) in all cases except for patients who consider time with toxicity to have a low relative value and time following disease progression to have a high relative value.

CONCLUSION

In patients with advanced follicular lymphoma, the clinical benefits of concomitant IFN can significantly offset the associated grade 3 or worse toxic effects. The magnitude of this clinical benefit depends on an individual patient's relative quality-of-life valuations for time with toxicity and time following disease progression.

Published: February 2017

PURPOSE

To assess the efficacy and maximum dose-intensity of a new topoisomerase I (topo I)-targeting agent, 9-aminocamptothecin (9-AC), in patients with relapsed or refractory lymphomas.

PATIENTS AND METHODS

Eligible patients had measurable disease and were considered incurable. 9-AC was infused over 72 hours at an initial dose rate of 40 microg/m2/h every 3 weeks with subsequent intrapatient escalations or reductions in 10-microg/m2/h increments based on toxicity. To assess the impact of granulocyte-colony stimulating factor (G-CSF) on dose-intensity, the first 16 patients received no G-CSF and the subsequent 29 patients received G-CSF on all cycles.

RESULTS

Forty-five patients received a total of 142 cycles of 9-AC. The patients' median age was 55 years, 73% had stage IV disease, and histologies included indolent and aggressive non-Hodgkin's lymphoma (NHL) in 33% and 58% of patients, respectively, and Hodgkin's lymphoma in 9%. Patients had received a median of two prior chemotherapy regimens, and 67% of patients had chemotherapy-sensitive disease. Of 40 assessable patients, 10 (25%) achieved a partial response (PR). Chemotherapy-sensitive patients had a 32% response rate compared with 8% in chemotherapy-resistant patients. With a median follow-up duration of 35 months, the median event-free survival (EFS) and overall survival times were 1.5 and 12.5 months, respectively, and the median duration of response was 5 months (range, 1 to 10). G-CSF significantly reduced the incidence of neutropenia and diarrhea, but did not permit a significant increase in dose-intensity.

CONCLUSION

9-AC had a reasonable response rate of 25% in heavily pretreated patients. The low response rate in patients with chemotherapy-resistant disease suggests that there is cross-resistance between 9-AC and standard chemotherapy. However, there was no association between 9-AC response and the number of prior regimens. Due to dose-limiting thrombocytopenia, G-CSF support did not increase dose-intensity, although individual patients benefited from the use of G-CSF.

Published: February 2017

PURPOSE

To determine the frequency of return of ovarian function after autologous bone marrow transplantation (ABMT), and the major factors that predict recovery.

PATIENTS AND METHODS

Records of 200 consecutive women who underwent ABMT at the University of Toronto Autologous Blood and Marrow Program (Toronto, Canada) were reviewed. Seventeen patients met the inclusion criteria, which were (1) alive at the time of evaluation, (2) disease-free at least 18 months after transplantation, (3) age younger than 50 years at transplantation, and (4) premenopausal before transplantation. Recovery of ovarian function was determined by pregnancy or regular menses, with no menopausal symptoms and an estradiol level greater than 20 pmol/L off hormonal therapy.

RESULTS

All 17 patients became menopausal immediately after ABMT. Five patients (29%) recovered ovarian function a median of 24 months post-ABMT (range, 6 to 48 months). The median age at transplantation of women with restored ovarian function was 19 years (range, 19 to 28 years) versus 30 years (range, 22 to 48 years) for those who did not regain function. Younger age at transplantation predicted ovarian recovery (P = .03) by means of a log-rank test. Only one of five women who regained ovarian function received total-body irradiation (TBI) compared with five of 12 women who did not. Univariate analysis suggested a trend for TBI to predict a sustained loss of ovarian function (P = .067). The number of regimens of induction or salvage chemotherapy that contained an alkylating agent ranged from none to five and was not predictive (P = .45).

CONCLUSION

All women became menopausal after ABMT but 29% recovered ovarian function. Younger age at transplantation predicted return of ovarian function, whereas TBI may have had a negative effect.

Published: February 2017

PURPOSE

To identify the readily available prognostic factors most helpful in predicting survival and to construct and validate a prognostic index for metastatic breast cancer (MBC) patients.

PATIENTS AND METHODS

Data from 233 MBC patients, accrued on a multiinstitutional randomized phase III trial (Japan Clinical Oncology Group [JCOG] study 8808), were analyzed to identify significant prognostic factors and a prognostic index was constructed by incorporating these prognostic factors. For validation of the prognostic index, another data set from 315 consecutive MBC patients, who had been treated with standard anthracycline-containing regimens, was analyzed.

RESULTS

In multivariate regression analyses, history of adjuvant chemotherapy (ADJCT) (P = .0005), presence of distant lymph nodes (DLNs) (P = .0117) and liver (HEP) (P = .0099) metastases, elevation of serum lactate dehydrogenase (LDH) (P < .0001), and shorter disease-free interval (DFI) (P < .0001) significantly contributed to poorer survival. The prognostic index was constructed as follows: Prognostic Index = ADJCT (not received = 0, received = 1) + DLNs (absent = 0, present = 1) + HEP (absent = 0, present = 1) + LDH (< or = one times normal = 0, > one times normal = 1) + DFI (> or = 24 months = 0, < 24 months = 2). With this prognostic index, patients could be stratified into three risk groups. The median survival times (MSTs) of low-, intermediate- and high-risk groups were 45.5, 24.6, and 10.6 months, respectively (P < .0001). This prognostic index was applied to the validation patients. The respective MSTs for each risk group were 49.6,22.8, and 10.0 months (P < .0001).

CONCLUSION

ADJCT, DLNs, HEP, LDH, and DFI were important prognostic factors for MBC patients. The prognostic index readily enables MBC patients to be stratified into three risk groups and is worth considering for future clinical trials.
Phase I/II study of the CAPABLE regimen for patients with poorly differentiated carcinoma of the nasopharynx.
Authors: Siu L L , Czaykowski P M , Tannock I F
Published: February 2017

PURPOSE

To evaluate the role of aggressive combination chemotherapy in patients with poorly differentiated carcinoma of the nasopharynx (NPC).

PATIENTS AND METHODS

In a prospective phase I/II study, 90 chemotherapy-naive patients with NPC (21 with very advanced locoregional disease, 18 with locoregional persistent and/or recurrent disease postradiotherapy, and 51 with metastatic disease) were treated with cyclophosphamide, doxorubicin, cisplatin, methotrexate, and bleomycin (CAPABLE). Two schedules of this regimen were used over a 9-year period, with the second schedule being a modification of the first in an attempt to minimize treatment-related toxicity.

RESULTS

Of 21 patients with very advanced local disease, one had a complete response (CR) and 17 had partial responses (PRs) (response rate, 86%). Seventeen of these 21 patients had subsequent radiotherapy. Of 17 patients with measurable locoregional disease either persistent and/or recurrent postradiotherapy, there were four CRs and three PRs (response rate, 41%). Of 44 patients with measurable metastatic disease, there were three CRs and 32 PRs (response rate, 80%). The median survival durations for these three groups of patients were 47, 16, and 14 months, respectively. The two chemotherapy schedules had similar received dose-intensities (RDIs) and produced similar response rates and survival. Toxicity was severe with frequent mucositis and myelosuppression. Overall, 37 patients required at least one hospital admission for management of toxic side effects and there were seven drug-related deaths. Three of the deaths were due to fulminant hepatitis, likely from reactivation of hepatitis B.

CONCLUSION

This aggressive regimen provides a high rate of tumor response, but limited palliation for most patients with recurrent or metastatic NPC. The results with chemotherapy followed by radiotherapy for patients with very advanced local disease are encouraging, but proof of benefit would require evaluation in a randomized trial.
Sequential intrahepatic fluorodeoxyuridine and systemic fluorouracil plus leucovorin for the treatment of metastatic colorectal cancer confined to the liver.

Published: February 2017

PURPOSE

Extrahepatic metastasis represents a frequent pattern of disease progression when fluorodeoxyuridine (FUDR) is given by the intraarterial route for the treatment of unresectable colorectal liver metastases. Systemic fluorouracil (5-FU) plus leucovorin was added to intrahepatic FUDR to prolong the duration of disease control.

METHODS

Only patients with colorectal cancer who had evidence of unresectable metastases confined to the liver were eligible. Laparotomy was performed to establish arterial perfusion of the liver. Cycles of intrahepatic FUDR followed by a 1-week rest period then intravenous chemotherapy with 5-FU plus leucovorin were administered until maximal regression of hepatic metastases. Maintenance chemotherapy with 5-FU plus leucovorin was then given until disease progression.

RESULTS

Fifty-seven patients entered this trial; four patients (7%) were ineligible and 13 (23%) did not receive any chemotherapy on study because of findings at laparotomy. The 40 eligible patients who began chemotherapy are included in the statistical analyses. Twenty-five patients (62% of those who received chemotherapy) experienced regression of liver metastases. The median time to tumor progression was 9 months, but only 3% remained progression-free at 24 months. The median survival duration was 18 months. Toxicity was tolerable with no cases of biliary sclerosis. One treatment-related fatality due to sepsis was observed.

CONCLUSION

Although short-term treatment results appear to be somewhat better than we have previously observed with intrahepatic FUDR alone, the sequential regimen did not have an impact on long-term, progression-free survival in patients with unresectable liver metastases. We are now investigating this regimen as surgical adjuvant therapy in selected patients following hepatic metastasectomy where this aggressive approach might have a greater therapeutic effect in the minimal residual disease setting.
