PURPOSE: To evaluate oral topotecan as single-agent, second-line therapy in patients with ovarian cancer previously treated with a platinum-based regimen.PATIENTS AND METHODS: Patients (N = 116) received oral topotecan 2.3 mg/m2daily for 5 days every 21 days. Eligibility criteria included histologic diagnosis of International Federation of Gynecology and Obstetrics stage III or IV epithelial ovarian cancer, bidimensionally measurable disease, prior platinum-containing chemotherapy, age ≥ 18 years, performance status ≤ 2, and life expectancy ≥ 12 weeks.RESULTS: Overall response rate was 21.6% (25 of 116 patients). Median duration of response was 25.0 weeks; median time to response was 8.4 weeks. Median time to progression was 14.1 weeks; median survival was 62.2 weeks. Grade 4 neutropenia was experienced by 50.4% of patients in 13.4% of courses administered. Grade 4 thrombocytopenia was experienced by 22.1% of patients in 5.1% of courses. Grade 3 or 4 anemia was experienced by 29.2% of patients in 8.5% of courses. Most frequent nonhematologic toxicities were predominantly (> 90%) grade 1 or 2 and included nausea, alopecia, diarrhea, and vomiting.CONCLUSION: Second-line oral topotecan administered at 2.3 mg/m2for 5 days every 21 days demonstrated activity in patients with progressive or recurrent ovarian cancer after first-line platinum-based chemotherapy. This activity was comparable to that seen in previous studies with intravenous topotecan. Grade 4 neutropenia was less frequent with oral topotecan than previously reported for intravenous topotecan. Oral topotecan is an active, tolerable, and convenient formulation of an established agent for the second-line treatment of advanced epithelial ovarian cancer and may also facilitate exploring prolonged treatment schedules.

PURPOSE: To evaluate the incidence and associated risk factors of solid cancers after bone marrow transplantation (BMT). PATIENTS AND METHODS: We analyzed 2,129 patients who had undergone BMT for hematologic malignancies at the City of Hope National Medical Center between 1976 and 1998. A retrospective cohort and nested case-control study design were used to evaluate the role of pretransplantation therapeutic exposures and transplant conditioning regimens. RESULTS: Twenty-nine patients developed solid cancers after BMT, which represents a two-fold increase in risk compared with a comparable normal population. The estimated cumulative probability (± SE) for development of a solid cancer was 6.1% ± 1.6% at 10 years. The risk was significantly elevated for liver cancer (standardized incidence ratio [SIR], 27.7; 95% confidence interval [CI], 1.9 to 57.3), cancer of the oral cavity (SIR, 17.4; 95% CI, 6.3 to 34.1), and cervical cancer (SIR, 13.3; 95% CI, 3.5 to 29.6). Each of the two patients with liver cancer had a history of chronic hepatitis C infection. All six patients with squamous cell carcinoma of the skin had chronic graft-versus-host disease. The risk was significantly higher for survivors who were younger than 34 years of age at time of BMT (SIR, 5.3; 95% CI, 2.7 to 8.6). Cancers of the thyroid gland, liver, and oral cavity occurred primarily among patients who received total-body irradiation. CONCLUSION: The risk of radiation-associated solid tumor development after BMT is likely to increase with longer follow-up. This underscores the importance of close monitoring of patients who undergo BMT.

PURPOSE: To determine the maximum-tolerated dose of tirapazamine when combined with cisplatin and radiation in patients with T3/4 and/or N2/3 squamous cell carcinoma of the head and neck. PATIENTS AND METHODS: The starting schedule was conventionally fractionated radiotherapy (70 Gy in 7 weeks) with concomitant cisplatin 75 mg/m2 and tirapazamine 290 mg/m2 (before cisplatin) in weeks 1, 4, and 7 and tirapazamine alone 160 mg/m2 three times a week in weeks 2, 3, 5, and 6. Positron emission tomography scans for tumor hypoxia (18F misonidazole) were performed before and during radiotherapy. RESULTS: We treated 16 patients with predominantly oropharyngeal primary tumors, including 10 patients with T4 or N3 disease. Febrile neutropenia occurred toward the end of radiotherapy in three out of six patients treated on the initial dose level. Two of these patients also developed grade 4 acute radiation reactions. Another 10 patients were treated with the same doses, but the week 5 and week 6 tirapazamine doses were omitted. This resulted in less neutropenia and only one dose-limiting toxicity (DLT) (febrile neutropenia), and eight out of 10 patients completed treatment without any dose omissions. In these 10 patients, the acute radiation toxicities were not obviously enhanced compared with chemoradiotherapy regimens using concurrent platinum and fluorouracil. 18F misonidazole scans detected hypoxia in 14 of 15 patients at baseline, with only one patient having detectable hypoxia at the end of treatment. With a median follow-up of 2.7 years, the 3-year failure-free survival rate was 69% (SE, 12%), the 3-year local progression-free rate was 88% (SE, 8%), and the 3-year overall survival rate was 69% (SE, 12%). CONCLUSION: DLT was due unexpectedly to febrile neutropenia, which could be overcome by omitting tirapazamine in weeks 5 and 6. The combination of tirapazamine, cisplatin, and radiotherapy resulted in remarkably good and durable clinical responses in patients with very advanced head and neck cancers. It warrants further investigation.

PURPOSE: To determine whether changes in whole-lung pulmonary function test (PFT) values are related to the sum of predicted radiation therapy (RT)-induced changes in regional lung perfusion. PATIENTS AND METHODS: Between 1991 and 1998, 96 patients (61% with lung cancer) who were receiving incidental partial lung irradiation were studied prospectively. The patients were assessed with pre- and post-RT PFTs (forced expiratory volume in one second [FEV1] and diffusion capacity for carbon monoxide [DLCO]) for at least a 6-month follow-up period, and patients were excluded if it was determined that intrathoracic recurrence had an impact on lung function. The maximal declines in PFT values were noted. A dose-response model based on RT-induced reduction in regional perfusion (function) was used to predict regional dysfunction. The predicted decline in pulmonary function was calculated as the weighted sum of the predicted regional injuries: equation [Formula: see text] where Vd is the volume of lung irradiated to dose d, and Rd is the reduction in regional perfusion anticipated at dose d. RESULTS: The relationship between the predicted and measured reduction in PFT values was significant for uncorrected DLCO (P = .005) and borderline significant for DLCO (P = .06) and FEV1 (P = .08). However, the correlation coefficients were small (range, .18 to .30). In patients with lung cancer, the correlation coefficients improved as the number of follow-up evaluations increased (range, .43 to .60), especially when patients with hypoperfusion in the lung adjacent to a central mediastinal/hilar thoracic mass were excluded (range, .59 to .91). CONCLUSION: The sum of predicted RT-induced changes in regional perfusion is related to RT-induced changes in pulmonary function. In many patients, however, the percentage of variation explained is small, which renders accurate predictions difficult.

PURPOSE: Recent reports of extramedullary disease (EMD) at recurrence in acute promyelocytic leukemia (APL) have raised increasing concern about a possible role of retinoic acid (RA) therapy. PATIENTS AND METHODS: We analyzed the risk of developing EMD localization at relapse in APL patients enrolled onto two consecutive studies of the Gruppo Italiano Malattie Ematologiche dell’Adulto. The studies investigated chemotherapy alone (LAP0389) versus RA plus chemotherapy (AIDA). RESULTS: When all relapse types were taken into account, 94 (51%) of 184 patients and 131 (18%) of 740 patients who attained hematologic remission underwent relapse in the LAP0389 and AIDA studies, respectively (P < .0001). EMD localization was documented in five (5%) of 94 and 16 (12%) of 131 patients (P = .08). Hematologic and/or molecular relapse was diagnosed concomitantly in all but two patients with EMD in the AIDA study. For patients in the LAP0389 and AIDA series, the probability of EMD localization of any type at relapse was 3% and 4.5%, respectively (P = .79), while the probability of CNS involvement was 0.6% and 2% (P = .28). No significant differences were found with regard to mean WBC count and promyelocytic leukemia/retinoic acid receptor-alpha junction type in comparisons of patients with EMD and hematologic relapse. CONCLUSION: APL patients receiving all-trans retinoic acid in addition to chemotherapy have no increased risk of developing EMD at relapse as compared with those treated with chemotherapy alone.

PURPOSE: Interleukin-11 (IL-11) is a thrombopoietic cytokine that attenuates postchemotherapy thrombocytopenia at doses of 50 μg/kg/d subcutaneously. Very little is known about the activity of IL-11 in patients with bone marrow failure states. PATIENTS AND METHODS: Our preliminary experience with IL-11 at doses of 50 μg/kg/d suggested that patients with bone marrow failure developed significant peripheral and pulmonary edema after the prolonged dosing necessary for treating these conditions. We, therefore, initiated a study of low-dose IL-11 (starting dose, 10 μg/kg/d). RESULTS: Sixteen patients were assessable for response. Six patients had diploid cytogenetics; the others had a variety of chromosomal abnormalities. Six (38%) of 16 patients showed a platelet response to IL-11, and two had a multilineage response (to IL-11 alone, n = 1; to IL-11 plus G-CSF and erythropoietin, n = 1). The median increase in peak platelet counts was 95 × 109/L above baseline in the responders (range, increase of 55 × 109/L to 130 × 109/L above baseline). Responders included five of 11 patients with myelodysplasia and one of four patients with aplastic anemia. Response durations were 12, 13, 14+, 25, 30, and 30+ weeks. Side effects of IL-11 were mild (peripheral edema, n = 7; conjunctival injection, n = 7; myalgia, n = 1; all grade 1). Seven patients had no side effects. CONCLUSION: Our pilot study suggests that administration of low-dose IL-11 (10 μg/kg/d) can raise platelet counts without significant toxicity in selected thrombocytopenic patients with bone marrow failure.

PURPOSE: To investigate the incidence of second cancers occurring in patients with early stage (I/II) non–small-cell lung cancer (NSCLC) treated with radiation therapy (RT) alone. PATIENTS AND METHODS: Seventy-eight patients had been treated with conventionally fractionated (CF) RT (1982 to 1987), and 116 patients had been treated with hyperfractionated (Hfx) RT (1988 to 1993). Tumor doses were 60 Gy for CF and 69.6 Gy (1.2 Gy bid) for Hfx. RESULTS: A total of 26 patients developed second cancers. The cumulative incidence of second cancer was 21.8% (SE, 4.7%) at 5 years and 34.8% (SE, 6.7%) at 10 years. For second lung cancers, it was 6.0% (SE, 2.8%) at 5 years and 14.2% (SE, 5.2%) at 10 years, and for second nonlung cancers, it was 16.3% (SE, 4.2%) at 5 years and 22.2% (SE, 5.7%) at 10 years. The rate of developing second cancer per patient per year was 4.3% (95% confidence intervals [CI], 2.7% to 5.9%), with the rates being 1.4% (CI, 0.5% to 2.3%) for the second lung cancers and 2.8% (CI, 1.5% to 4.1%) for second nonlung cancers. The rate of developing second cancers during the first and second 5-year period after RT (0 to 5 and 5 to 10 years) was 4.3% (CI, 2.4% to 6.2%) and 4.2% (CI, 0.6% to 7.8%), respectively, for all cancers. These rates were 1.0% (CI, 0.1% to 1.9%) and 2.2% (CI, 0% to 4.6%), respectively, for second lung cancers, and 3.2% (CI, 1.6% to 4.8%) and 1.5% (CI, 0% to 3.6%), respectively, for second nonlung cancers. CONCLUSION: Long-term survivors after RT alone for early stage NSCLC carry the same risk of developing second cancer, either lung or nonlung, as their counterparts treated surgically when the results of this study are compared with those of the published literature.

PURPOSE: To determine the safety and feasibility of delivering multiple cycles of front-line high-dose carboplatin, paclitaxel, and topotecan with peripheral-blood stem-cell (PBSC) support. PATIENTS AND METHODS: Patients were required to have a malignant solid tumor for which they had received no prior chemotherapy. Mobilization of PBSC was achieved with either filgrastim alone or in combination with cyclophosphamide and paclitaxel. Patients then received three or four cycles of high-dose carboplatin (area under the concentration-time curve [AUC] 16), paclitaxel (250 mg/m2), and topotecan (10-15 mg/m2), with the latter two agents administered as 24-hour infusions and supported with PBSC and filgrastim. Cycles were repeated every 28 days. RESULTS: Twenty patients were enrolled onto the trial and were assessable for toxicity and clinical outcome. Dose-limiting toxicities were stomatitis and prolonged hematopoietic recovery. The maximum-tolerated dose of topotecan was 12.5 mg/m2 when given with high-dose carboplatin and paclitaxel for three cycles. Four cycles were able to be given with a dose of topotecan of 10 mg/m2. The pharmacokinetics of each compound were not affected by the other agents. Eleven (85%) of 13 patients with assessable disease responded. CONCLUSION: Multiple cycles of high-dose carboplatin, paclitaxel, and topotecan can be safely administered with filgrastim and PBSC support. The recommended doses for phase II study are carboplatin AUC 16, paclitaxel 250 mg/m2, and topotecan 10 mg/m2. Trials are currently being conducted with this regimen as front-line treatment in patients with advanced ovarian cancer and extensive small-cell carcinoma. This approach remains experimental and should be used only in the context of a clinical trial.

PURPOSE: To determine the relative efficacy of a cyclophosphamide epirubicin and fluorouracil (CEF) regimen compared with an intravenous (IV) cyclophosphamide, methotrexate, and fluorouracil (CMF) combination in metastatic breast cancer. PATIENTS AND METHODS: Patients were randomized to receive either CEF (cyclophosphamide 400 mg/m2 IV, epirubicin 50 mg/m2 IV, and fluorouracil 500 mg/m2 IV on days 1 and 8), or CMF (cyclophosphamide 500 mg/m2 IV, methotrexate 40 mg/m2 IV, and fluorouracil 600 mg/m2 IV on days 1 and 8). Treatment was given in 3- to 4-week cycles for a total of six to nine cycles. RESULTS: A total of 460 patients (223 CEF and 237 CMF) were randomized. Overall response rate was superior for CEF than CMF in all randomized patients (57% v 46%, respectively; P = .01) and in the assessable subset (66% v 52%, respectively; P = .005). With a median follow-up of more than 20 months, time to progression (TTP) was significantly longer with CEF than CMF (median 8.9 v 6.3 months, respectively; P = .0064), as was time to treatment failure (TTF) (median 6.2 v 5.0 months, respectively; P = .01). Significant survival differences were not observed between CEF and CMF (median 20.1 v 18.2 months, respectively; P = .23). Granulocytopenia and infections were similar in both arms. Grade 3/4 nausea/vomiting and alopecia were more frequent with CEF, whereas diarrhea was more frequent with CMF. Cardiac toxicity, primarily asymptomatic, required withdrawal from study of 15 patients on CEF (7%) and one patient on CMF. CONCLUSION: This CEF regimen safely provides significantly better tumor control than CMF, manifest as a higher response rate, and longer TTP and TTF, but not survival, when used as first-line chemotherapy for metastatic breast cancer.

Published: February 2017

PURPOSE: Validated end points are lacking for clinical trials in hormone-refractory prostate cancer (HRPC). Controversy remains regarding the utility of a posttreatment decline of prostate-specific antigen (PSA). The purpose of this study was to determine whether posttreatment declines in PSA were associated with clinical measures of improvement in a randomized phase III trial of suramin plus hydrocortisone versus placebo plus hydrocortisone. PATIENTS AND METHODS: A total of 460 HRPC patients were randomized to receive suramin plus hydrocortisone (n = 229) or placebo plus hydrocortisone (n = 231). All patients had symptomatic, metastatic HRPC requiring opioid analgesics. Clinical end points evaluated included overall survival, objective progression-free survival (OPFS), and time to pain progression (TTPP). An evaluation of overall survival, OPFS, and TTPP as a function of a PSA decline of ≥ 50%, lasting at least 28 days, was undertaken by using a landmark analysis at 6, 9, and 12 weeks. A multivariate analysis of the impact of PSA decline was performed on these clinical end points. RESULTS: A decline in PSA of ≥ 50% lasting ≥ 28 days was significantly associated with a prolonged median overall survival, OPFS, and TTPP, both in the entire group and the suramin plus hydrocortisone group at all three landmarks in both univariate and multivariate analysis. CONCLUSION: In this prospective, randomized trial of suramin plus hydrocortisone versus placebo plus hydrocortisone, a posttherapy decline in PSA of ≥ 50%, lasting 28 days, was associated with prolonged median overall survival, improved median progression-free survival, and median TTPP. This analysis suggests that a posttreatment decline in PSA may be a reasonable intermediate end point in HRPC trials and calls into question the clinical utility of preclinical assays evaluating the in vitro effect of given agents on PSA secretion.

PURPOSE: As therapy for locally advanced non–small-cell lung carcinoma (NSCLC) improves, brain metastases (BM) may become a greater problem. We analyzed our chemoradiation experience for patients at highest risk for the brain as the first failure site. METHODS: Records for 150 consecutive patients with stage II/III NSCLC treated definitively with chemoradiation from June 1992 to June 1998 at the University of Pennsylvania were reviewed. Most patients (89%) received cisplatin, paclitaxel, or both. All had negative brain imaging before treatment. Posttreatment brain imaging was performed for suspicious symptoms. Incidence of BM was examined as a function of age, sex, histology, stage, performance status, weight loss, tumor location, surgery, radiation dose, initial radiation field, chemotherapy regimen, and chemotherapy timing. RESULTS: Crude and 2-year actuarial rates of BM were 19% and 30%, respectively. Among pretreatment parameters, stage IIIB was associated with a higher risk of BM (P < .04) versus stage II/IIIA. Histology alone was not significant (P < .12), although patients with IIIB nonsquamous tumors had an exceptionally high 2-year BM rate of 42% (P < .01 v all others). Examining treatment-related parameters, crude and 2-year actuarial risk of BM were 27% and 39%, respectively, in patients receiving chemotherapy before radiotherapy and 15% and 20%, respectively, when radiotherapy was not delayed (P < .05). On multivariate analysis, timing of chemotherapy (P < .01) and stage IIIA versus IIIB (P < .01) remained significant. CONCLUSION: Patients with later stage, nonsquamous NSCLC, particularly those receiving induction chemotherapy, have sufficiently common BM rates to justify future trials including prophylactic cranial irradiation.
