PURPOSE The records of 557 consecutive adult recipients of allogeneic-related and -unrelated and syngeneic bone marrow transplants (BMTs) were reviewed to determine the incidence of secondary cancers. PATIENTS AND METHODS Four hundred fifty-six patients were transplanted for acute lymphocytic leukemia (ALL; n = 79), acute myelogenous leukemia (AML; n = 182), and chronic myelogenous leukemia (CML; n = 195); 42 patients were transplanted for aplastic anemia (AA) and 59 for a variety of other hematologic and nonhematologic disorders, malignant and nonmalignant. Conditioning regimens included high-dose chemotherapy with or without total-body irradiation (TBI). Statistical analyses determined the cumulative incidence of developing a secondary cancer and elucidated the associated risk factors. Complete records (1 to 24 years of follow-up) on all patients were available. RESULTS Nine patients developed 10 secondary cancers for a cumulative actuarial risk of 12% (95% confidence interval [CI], 4.3 to 23.0) 11 years after transplant. The age-adjusted incidence of secondary cancer was 4.2 times higher than that of primary cancer in the general population. Eight of the 10 were epithelial in origin and three were cutaneous. TBI and acute graft-versus-host disease (GVHD) with a severity > or = grade II were associated with the development of any secondary cancer. On the other hand, chronic GVHD was a risk factor only for the development of secondary skin neoplasms. CONCLUSION Adult recipients of BMT face a significant risk of developing a secondary malignancy. Their risk is similar to that of other patients with hematologic malignancies who are treated with chemoradiotherapy only. Epithelial tumors, rather than the more commonly reported Epstein-Barr virus (EBV)-associated lymphomas, were most common. The fact that we did not routinely use T-cell-depleted marrow grafts nor anti-T-cell immunoglobulin for the treatment of acute GVHD may explain this variance.

PURPOSE A trial of paclitaxel was conducted in patients with previously treated germ cell tumors (GCT). As the identification of new agents in GCT may be compromised by restricting entry criteria to heavily pretreated patients, an alternative trial design was used in which eligibility was restricted to patients with limited prior therapy. PATIENTS AND METHODS Patients were eligible if their prior therapy was limited to one cisplatin-based regimen or < or = six cycles of prior cisplatin-based therapy. Paclitaxel 250 mg/m2 was administered by continuous infusion over 24 hours every 21 days. The dose of paclitaxel was modified for each patient based on toxicity. Granulocyte colony-stimulating factor (G-CSF) 5 micrograms/kg/d was administered during nadir periods. RESULTS Thirty-one patients were treated; eight patients (26%) achieved a partial (n = 5) or a complete (n = 3) response. Responses were achieved in patients who had failed to respond to treatment with cisplatin, ifosfamide, and etoposide, and in patients with poor prognostic features, ie, mediastinal primary tumor site and patients with a best prior response of an incomplete response to cisplatin therapy. One complete responder remains continuously free of disease at 13+ months and one of the five patients who achieved a partial response remains progression-free at 14+ months. CONCLUSION Paclitaxel has antitumor activity in GCT and warrants continued study in combination chemotherapy. Phase I/II trials will address its role in combination with cisplatin and ifosfamide and as a part of dose-intensive therapy. Furthermore, the study showed that a trial design in which eligibility criteria limits prior therapy was feasible, resulted in the identification of antitumor activity in a new agent, and may be considered in future trials for other promising new agents in GCT.

PURPOSE AND METHODS This retrospective analysis of 501 patients with gynecologic cancer treated with chemotherapy evaluates the relationship between platelet count and clinical bleeding, as well as the clinical effects of platelet transfusion therapy. Thrombocytopenic patients were divided into six groups according to platelet counts, and major or minor bleeding manifestations were documented. Thrombocytopenia was defined as a platelet count less than 100,000/microL. RESULTS Thrombocytopenia occurred in 182 (36.3%) patients over 808 of 1,546 chemotherapy cycles (52%). No intracranial or life-threatening bleeding occurred in any patient. The majority of patients (139 [76.4%]) had no clinical bleeding. Minor bleeding, such as purpura, occurred in 34 patients (18.7%) and 44 cycles (5.4%). Major bleeding occurred in nine patients (4.9%) and 10 cycles (1.3%). Five major bleeding events occurred in 49 patients with platelet counts between 0 and 10,000/microL. Forty-three of these patients received platelet transfusions. Thirty-eight of 43 transfused patients (88.3%) had no bleeding. Of the remaining five patients, two were transfused prophylactically with no effect. Three major bleeding events occurred in patients with platelet counts that ranged from 11,000 to 20,000/microL, but these were due to chronic instrumentation or trauma. In patients with platelet counts more than 20,000/microL, major bleeding occurred only from necrotic metastatic lesions. Random-donor platelet transfusions provided inconsistent increments in platelet counts. Overall, 27.5% of patients achieved the expected increase in platelet number based on units of platelet concentrate transfused. The use of single-donor or human leukocyte antigen (HLA)-matched platelets did not provide greater increments in those patients who were refractory to random-donor platelets. CONCLUSION Platelet counts > or = 10,000/microL are not associated with spontaneous major bleeding. Prophylactic platelet transfusions in patients with gynecologic malignancies and chemotherapy-induced thrombocytopenia should be limited to those with platelet counts < or = 10,000/microL, provided they are not bleeding and have no major anatomic or pathophysiologic precursors of bleeding.

PURPOSE The Canadian multicenter trial for advanced non-small-cell lung cancer (NSCLC) reported survival benefit for chemotherapy when best supportive care was compared with vindesine-cisplatin (VP) and the combination of cyclophosphamide, doxorubicin, and cisplatin (CAP). We examined received drug delivery to document dose-intensity (DI) and total dose of drugs given to various groups in this patient population. PATIENTS AND METHODS Plots of cumulatively received chemotherapy against time were used to evaluate drug delivery by regimen, major prognostic factors, and response status. RESULTS Individual CAP patients show a narrow range of received DI, with the median similar to protocol. Drug delivery analysis exposed a wide range of received DI for both drugs in the more intensive VP regimen, and the median received DI was below protocol. The median received DI for cisplatin was still higher for VP than CAP, but only during the first 8 weeks of protocol treatment (20 v 10 mg/m2/wk); thereafter, the ongoing received cisplatin DI was the same (10 mg/m2/wk). The median received DI for cisplatin in each regimen was not influenced by stage, performance status, prior weight loss, sex, or response status. VP-treated patients received a higher total dose of cisplatin than CAP patients (median, 255 mg/m2 v 112.5 mg/m2; P < .0001). Median cisplatin total dose was similar for patients with a chemotherapy response or stable disease and threefold greater than for patients with progressive disease for both regimens. Although patients with chemotherapy response and stable disease had similar survival outcomes for both CAP and VP, the VP regimen had a higher proportion of patients without progressive disease (P = .004), which resulted in an overall survival advantage (P = .01). CONCLUSION The major prognostic factors for advanced NSCLC do not exert their influence on outcome by affecting deliverable chemotherapy DI. Regimen and treatment response determined total dose. Because stable disease patients usually outnumber responding patients in advanced NSCLC trials, controlled studies should be performed that allow assessment of the impact of total received dose on outcome according to response status.

PURPOSE To evaluate oral ondansetron in the prevention of total-body irradiation (TBI)-induced nausea and vomiting. METHODS Twenty patients who received 4 days of TBI as part of their preparative regimen before bone marrow transplantation were randomized to receive either 8-mg oral doses of ondansetron or placebo. Administration of drug was double-blinded. Initial rescue therapy consisted of intravenous (i.v.) ondansetron 0.15 mg/kg following two or more emetic episodes between successive fractions of TBI or five total emetic episodes during the 4 days of therapy. If, after receipt of i.v. ondansetron, patients had two or more emetic episodes between fractions of TBI or five total emetic episodes, additional antiemetics were administered. RESULTS Patients who received oral ondansetron had significantly fewer emetic episodes compared with those who received placebo (P = .005) over the entire 4-day study period. Oral ondansetron was also significantly superior to placebo with respect to the time of onset of emesis or rescue (P = .003). Six of 10 patients treated with oral ondansetron completed the study without additional antiemetic therapy, while none of 10 patients who received placebo completed the study without rescue antiemetic therapy. Six placebo patients who received initial rescue therapy with i.v. ondansetron required no additional antiemetics. No relationships were apparent between peak ondansetron concentration (Cmax) or area under the concentration versus time curve (AUC) and number of emetic episodes. CONCLUSION Oral ondansetron is an effective therapy for the prevention of emesis induced by TBI.

PURPOSE This study evaluated tropisetron (Navoban; Sandoz Pharma, Basle, Switzerland)-based combination therapy in patients who had incomplete control of chemotherapy-induced nausea or vomiting when using tropisetron as a single antiemetic agent. PATIENTS AND METHODS One thousand seventy-two patients, who were scheduled to receive at least two identical cycles of emetogenic chemotherapy, were treated with 5 mg tropisetron once daily in their first chemotherapy course. A 2 x 2 x 2 factorial design was used to evaluate three additional treatments to the recommended 5 mg once daily (intravenously [i.v.] on day 1; orally on days 2 through 6) tropisetron regimen during course 2 in those patients who had shown incomplete control of nausea and/or vomiting on any day of course 1. Four hundred forty-five patients were centrally randomized to receive, in addition, open-label dexamethasone (day 1, 0.2 mg/kg i.v.; days 2 through 6, 8 mg orally) and/or open-label alizapride (day 1, 100 mg i.v. and 4 x 50 mg orally; days 2 through 6, 4 x 50 mg orally) and/or double-blind tropisetron (ie, doubling the dose to 10 mg once daily) or corresponding placebo. RESULTS Complete response rates (no nausea and no vomiting) were 72% for day 1 and 48% for days 1 through 6 of course 1. During course 2, more complete responders were observed when dexamethasone was added, both for day 1 (76% v 66%, P = .020) and for days 1 through 6 (50% v 34%, P = .0004). A moderate increase in the complete response rate was seen with the addition of conventional-dose alizapride (day 1, 75% v 68%, P = .14; days 1 through 6: 47% v 37%, P = .041). Doubling the dose of tropisetron did not change the complete response rate. CONCLUSION The addition of dexamethasone significantly increases the complete response rate of both acute and delayed emesis in patients who have incomplete disease control with tropisetron alone.

PURPOSE Past research that has compared cancer treatment tolerance between elderly and nonelderly cancer patients has been contradictory. Some investigators concluded that there is no difference between the groups, while others demonstrated elderly patients experienced less tolerance to treatment. As a result, some physicians discriminate against elderly cancer patients by not entering them onto clinical trials out of a belief that they will not tolerate the therapy. METHODS An analysis was performed using the Illinois Cancer Center (ICC) data base, which contains treatment information for all patients registered onto phase II trials. A maximum of 672 cases was available for evaluation of 11 treatment-related variables. RESULTS The results demonstrated no significant differences between elderly and nonelderly patients for the following seven treatment-related variables: performance status (PS), number of dose reductions, number of treatment interruptions, total days of delay, best response, reason off-study, and number of grade 3 or greater toxicities. Minor differences were detected for number of courses and number of dose escalations. CONCLUSION Based on these results, elderly patients should not be denied access to cancer clinical trials relative to age alone.

PURPOSE Optimal postremission therapy remains controversial in adult patients with acute lymphoblastic leukemia (ALL). In a large multicentric trial (LALA87), we compared allogeneic bone marrow transplantation (BMT) with other postremission therapies (chemotherapy or autologous transplantation) using the result of the human leukocyte antigen (HLA) typing as a random allocation. PATIENTS AND METHODS Patient eligibility requirements were as follows: (1) inclusion in LALA87 trial, (2) complete response to induction or salvage therapy, (3) age 15 to 40 years, and (4) at least one potential sibling donor. Patients with an HLA-identical sibling were assigned to the BMT group, while patients without a sibling donor constituted the control group. Allogeneic transplantation was scheduled for patients in the BMT group; in the control group, patients were randomly allocated to receive chemotherapy or autologous transplantation. RESULTS Of 284 eligible points, 257 entered the study: 116 were allocated to the BMT group and 141 to the control group. The 5-year survival rates were not statistically significantly different between the two groups. When only patients with high-risk ALL were considered (those with [1] Philadelphia chromosome [Ph1] ALL, [2] null or undifferentiated ALL, or [3] c-ALL with either age greater than 35 years or WBC count > 30 x 10(9)/L or time to achieve complete remission > 4 weeks), overall survival (P = .03) and disease-free-survival (P = .01) were better for the BMT group compared with the control group (5-year overall survival rates, 44% v 20%; 5-year disease-free survival rates, 39% v 14%). CONCLUSION Allogeneic transplantation does not improve survival in patients with standard-risk ALL and should be recommended only for patients with adverse prognostic factors.

PURPOSE To investigate and define better the role of salvage surgery for patients with chemorefractory gestational trophoblastic disease (GTD). PATIENTS AND METHODS A retrospective review of medical records at The University of Texas M.D. Anderson Cancer Center identified 33 patients with chemorefractory GTD who underwent salvage surgery between 1962 and 1991. The end points selected for analysis were serologic response and survival. RESULTS Initial salvage procedures consisted of 29 hysterectomies, four thoracotomies, and one nephrectomy (in conjunction with a hysterectomy). Fourteen patients (42%) had a serologic complete response (CR) to surgery (normalization of human chorionic gonadotropin [hCG]), 10 (30%) had a partial response (> 50% decrease in hCG level), and nine had no response (< or = 50% decrease in hCG level). Of 19 patients who received further chemotherapy, eight (42%) attained a CR. Four patients underwent a second salvage surgery: two thoracotomies, one craniotomy, and one partial hepatectomy. All achieved a CR. The probability of achieving a CR was influenced by the time from diagnosis to surgery, number of preoperative disease sites, preoperative World Health Organization (WHO) score, and histologic type. Survival was influenced by the type of antecedent pregnancy, number of preoperative regimens, number of preoperative disease sites, time from diagnosis to surgery, and preoperative WHO score. CONCLUSION Based on the findings of this study, it appears that a select subset of patients with chemorefractory GTD who have a limited number of clinically detectable tumor foci may benefit from salvage surgery.

PURPOSE We conducted a phase I trial of a 3-hour infusion of Taxol (paclitaxel; Bristol-Myers Squibb Co, Princeton, NJ) to identify the maximum-tolerated dose of Taxol as a 3-hour infusion with and without granulocyte colony-stimulating factor (G-CSF) support. MATERIALS AND METHODS Thirty-five patients with advanced, untreatable malignancies were treated with a 3-hour infusion of Taxol once every 3 weeks. Groups of three patients were entered at escalating dose levels of Taxol in a traditional phase I design in each of two parallel arms: arm A, without G-CSF, and arm B, with G-CSF. Patients assigned to the G-CSF arm received G-CSF 5 micrograms/kg/d subcutaneously starting on day 2 for 9 to 14 days. All patients were pretreated with dexamethasone, diphenhydramine, and ranitidine, and were monitored continuously for cardiac arrhythmias during the first treatment. RESULTS Dose-limiting myelosuppression with Taxol without G-CSF was observed at the 250-mg/m2 dose level. The dose-limiting toxicity for Taxol with G-CSF was peripheral neuropathy at the 300-mg/m2 dose level. One of 35 patients (2.8%) had a grade 3 anaphylactic reaction at 250 mg/m2. No clinically significant cardiac arrhythmias were documented. Twenty-seven of 111 courses (24%) were associated with grade 3 arthralgias or myalgias requiring narcotics for pain control. Taxol plasma concentrations declined in a triexponential fashion, with a final elimination half-life of 10 to 12 hours. The peak Taxol plasma concentrations and total area under the curve (AUC) increased with increasing doses of Taxol, although this increase appeared to be somewhat nonlinear. CONCLUSION The maximum dose of Taxol recommended for phase II and III studies, when administered as a 3-hour infusion alone and with G-CSF support, is 210 mg/m2 and 250 mg/m2, respectively. No increased incidence of hypersensitivity reactions or other side effects were observed, with the possible exception of arthralgias and myalgias. If ongoing trials demonstrate that a 3-hour infusion is as efficacious as a 24-hour infusion, we conclude that with proper monitoring and premedication, high-dose Taxol can be safely administered in the outpatient setting.

PURPOSE Because each of very different treatments for Hodgkin's disease (HD) may result in a high rate of cure, attention is currently focused on toxicity. This prospective study was designed to assess the effects of mediastinal irradiation and bleomycin chemotherapy on pulmonary function. PATIENTS AND METHODS Patients were treated from 1980 to 1990 on randomized controlled trials at Stanford University. Pulmonary function was tested before treatment (baseline), early after treatment (< 15 months), and more than 36 months posttherapy. Treatment options in the 145 patients were grouped as I (mediastinal radiotherapy), II (mediastinal radiotherapy plus bleomycin), and III (bleomycin) for analyses of variance (ANOVAs). A variety of regression models were used to predict early and late effects on pulmonary function. RESULTS A decrease in forced vital capacity (FVC) and diffusing capacity (DLCO) in the first 15 months after treatment followed by recovery after 36 months was observed for most patients. Patients who received mediastinal radiotherapy (RT) had a more pronounced reduction in pulmonary function and less complete recovery. Overall, 3 or more years after treatment, 32% of group I patients, 37% of group II patients, and 19% of group III patients had FVC values less than 80% of predicted, while only 7% of patients had a DLCO less than 80% of predicted. Linear regression identified baseline measurement as the only significant predictor of change in percent predicted FVC or DLCO; patients with higher baseline values had greater decrements after therapy. Mantle RT was the only significant treatment variable, predictive of FVC and DLCO within 15 months and FVC at 36 or more months. No patient experienced pulmonary toxicity severe enough to require hospitalization. CONCLUSION This prospective analysis of pulmonary function after treatment for HD showed that mediastinal RT was the only treatment variable that achieved statistical significance. Although there were no significant interactions between mediastinal RT and bleomycin or Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH) chemotherapy, the patient numbers were small after correction for mediastinal mass size and drug regimen such that an effect could have been missed. The mild reduction in pulmonary function should be factored into the overall assessment of morbidity risk for each of the potentially curative treatments included in this study. As with all reports of late effects, these data should be interpreted with respect to the population tested, details of the treatment administered, methods of measurement, and length of follow-up.
