PURPOSE To determine the cardioprotective effect of dexrazoxane (DZR) used in a doxorubicin-based combination therapy in advanced breast cancer. PATIENTS AND METHODS Between November 1988 and January 1991, 534 patients with advanced breast cancer were randomized to two multicenter, double-blind studies (088001 and 088006). Patients received fluorouracil, doxorubicin, and cyclophosphamide (FAC) with either DZR (DZR-to-doxorubicin ratio, 10:1) or placebo (PLA) every 3 weeks and were monitored with serial multiplegated acquisition (MUGA) scans. RESULTS The hazards ratio (HR) of PLA to DZR for a cardiac event, which was predefined ejection fraction changes or congestive heart failure (CHF), was 2.63 (95% confidence interval [CI], 1.61 to 4.27; P < .001) for 088001 and 2.00 (95% CI, 1.01 to 3.96; P = .038) for 088006. The objective response rates for 088001 were 46.8% for DZR and 60.5% for PLA, a difference of 14% (95% CI, -25% to -2%; P = .019), and for 088006 were 53.7% for DZR and 49.3% for PLA, a difference of 4% (95% CI, -13% to 22%; P = .63). Time to progression and survival were not significantly different between treatment arms in either study. Toxicities on the DZR arms included lower granulocyte and platelet counts at nadir (P = .009 and P = .004, respectively) and more pain on injection (P = .001), with no difference in the rates of fever, infection, or hemorrhage. CONCLUSION DZR had a significant cardioprotective effect as measured by noninvasive testing and clinical CHF. One of the two studies (088001) showed a lower response rate with DZR, but time to progression and survival were not significantly different. DZR is the first agent shown to reduce cardiotoxicity from doxorubicin.

PURPOSE Salvage therapy for disseminated germ cell tumors of all histologic subtypes with vinblastine, ifosfamide, and cisplatin (VeIP) will cure approximately 25% of patients. The purpose of this study was to evaluate the activity of VeIP in patients with recurrent seminoma. PATIENTS AND METHODS We conducted a retrospective review of 24 patients with recurrent seminoma who were treated at Indiana University with VeIP as second-line chemotherapy. All patients had received cisplatin-containing regimens as primary chemotherapy and seven had also received prior pelvic radiotherapy. All patients received four courses of VeIP. RESULTS The minimum follow-up duration was 2 years (range, 2 to 9.1), with a median follow-up time of 7 years. Twenty of 24 patients (83%) achieved a complete remission (CR) following VeIP alone. One additional patient was rendered disease-free (NED) with the resection of residual carcinoma. Eight patients have relapsed. Four of six patients with extragonadal primary tumors and two of four who failed to achieve CR with initial chemotherapy are continuously NED with VeIP. Overall, 13 of 24 (54%) are long-term survivors with VeIP salvage chemotherapy. CONCLUSION VeIP has significant curative potential in patients with recurrent seminoma and appears to produce a higher CR rate and more long-term survivors than is achieved in patients with nonseminomatous disease.

PURPOSE To investigate the pharmacokinetics and pharmacodynamics of 9-aminocamptothecin (9-AC) infused over 72 hours at doses of 5 to 74 micrograms/m2/h. PATIENTS AND METHODS 9-AC lactone and total (lactone plus carboxylate) plasma concentrations were measured in 44 patients with solid tumors using a high-performance liquid chromatography (HPLC) assay. Fifteen patients underwent extended pharmacokinetic sampling to determine the distribution and elimination kinetics of 9-AC. RESULTS At steady-state, 8.7% +/- 4.7% (mean +/- SD) of the total drug circulated in plasma as the active 9-AC lactone. Clearance of 9-AC lactone was uniform (24.5 +/- 7.3 L/h/m2) over the entire dose range examined; however, total 9-AC clearance was nonlinear and increased at higher dose levels. In 15 patients treated at dose levels > or = 47 micrograms/m2/h, the volume of distribution at steady-state for 9-AC lactone was 195 +/- 114 L/m2 and for total 9-AC it was 23.6 +/- 10.6 L/m2. The elimination half-life was 4.47 +/- 0.53 hours for 9-AC lactone and 8.38 +/- 2.10 hours for total 9-AC. In pharmacodynamic studies, dose-limiting neutropenia correlated with steady-state lactone concentrations (Css) R2 = .77) and drug dose (R2 = .71). CONCLUSION Plasma 9-AC concentrations rapidly declined to low levels following the end of a 72-hour infusion and the mean fraction of total 9-AC circulating in plasma as the active lactone was less than 10%. The pharmacokinetics of 9-AC may have a great impact on its clinical activity and should be considered in the design of future clinical trials of this topoisomerase I inhibitor.

PURPOSE A phase I trial of docetaxel was performed to determine the maximum-tolerated dose (MTD), the dose-limiting toxicities, and the incidence and severity of other toxicities in children with refractory solid tumors. PATIENTS AND METHODS Forty-four children received 103 courses of docetaxel administered as a 1-hour intravenous infusion every 21 days. Doses ranged from 55 to 150 mg/m2, MTD was defined in heavily pretreated and less heavily pretreated (< or = 2 prior chemotherapy regimens, no prior bone marrow transplantation [BMT], and no radiation to the spine, skull, ribs, or pelvic bones) patients. RESULTS Dose-related neutropenia was the primary dose-limiting toxicity. The MTD in the heavily pretreated patient group was 65 mg/m2, but the less heavily pretreated patients tolerated a significantly higher dose of docetaxel (maximum-tolerated dose, 125 mg/m2). Neutropenia and constitutional symptoms consisting of malaise, myalgias, and anorexia were the dose-limiting toxicities at 150 mg/m2 in the less heavily pretreated patients. Thrombocytopenia was not prominent, even in patients who experienced dose-limiting neutropenia. Common nonhematologic toxicities of docetaxel included skin rashes, mucositis, and mild elevations of serum transaminases. Neuropathy was uncommon. Peripheral edema and weight gain were observed in two of five patients who received more than three cycles of docetaxel. A complete response (CR) was observed in one patient with rhabdomyosarcoma, a partial response (PR) in one patient with peripheral primitive neuroectodermal tumor (PPNET), and a minimal response (MR) in two patients with PPNET. Three of the four responding patients were treated at doses > or = 100 mg/m2. CONCLUSION The recommended phase II dose of docetaxel administered as a 1-hour intravenous infusion in children with solid tumors in 125 mg/m2. Because neutropenia was the dose-limiting toxicity and thrombocytopenia was mild, further escalation of the dose should be attempted with granulocyte colony-stimulating factor (G-CSF) support.

PURPOSE To assess the incidence of lymphoma transformation in the natural history of follicular lymphoma (FL) patients and the factors that are predictive of this event. PATIENTS AND METHODS Two hundred twenty patients with FL treated in our institution between 1975 and 1990, with a median follow-up duration of 9 years, were included in this retrospective analysis. RESULTS Transformation was proven by histology in 34 patients or by cytology in 13 patients and was considered as highly probable on clinical arguments in five patients for an overall incidence of 24%. The probability of transformation was 22% at 5 years and 31% at 10 years and tended to plateau after 6 years. Predictive factors for transformation were nonachievement of complete remission (CR) after initial therapy (P < 10(-4), low serum albumin level (< 35 g/L) (P = .001), and beta 2-microglobulin level greater than 3 mg/L (P = .02) at diagnosis. In a multiparametric analysis, only beta 2-microglobulin level retained prognostic significance for freedom-from-transformation (FFT) survival (P = .04). Transformation accounted for 44% of deaths and was associated with a poor outcome, with a median survival time of 7 months. CONCLUSION Transformation is an early event in the course of the disease and is mainly observed in patients with known adverse prognostic factors or those who do not achieve CR after initial treatment. These findings may be useful to select follicular lymphoma patients for intensive therapeutic approaches.

PURPOSE The optimal dose of granulocyte colony-stimulating factor (G-CSF) for mobilization of allogeneic-blood stem cells (AlloBSC) has yet to be determined. As part of a prospective trial, 41 related human leukocyte antigen (HLA)-matched donors had blood cells mobilized with G-CSF at 5 micrograms/kg/d by subcutaneous administration. The purpose of this trial was to monitor adverse effects during G-CSF administration and stem-cell collection, to determine the optimal timing for stem-cell collection, and to determine the cellular composition of stem-cell products following G-CSF administration. PATIENTS AND METHODS The median donor age was 42 years. Apheresis began on day 4 of G-CSF administration. At least three daily 12-L apheresis collections were performed on each donor. A minimum of 1.0 x 10(6) CD34+ cells/kg (recipient weight) and 8.0 x 10(8) mononuclear cells/kg were collected from each donor. All collections were cryopreserved in 5% dimethyl sulfoxide and 6% hydroxyethyl starch. RESULTS Toxicities associated with G-CSF administration and the apheresis process included myalgias/arthralgias (83%), headache (44%), fever (27%), and chills (22%). The median baseline platelet count of 242 x 10(4)/ mL decreased to 221, 155, and 119 x 10(6)/mL on days 4, 5, and 6 of G-CSF administration, respectively. Median numbers of CD34+ cells in collections 1, 2, and 3 were 1.99, 2.52, and 3.13 x 10(6)/kg, respectively. The percentage and total number of CD4+, CD8+, and CD56+/CD3- cells remained relatively constant during the three collections. Median total numbers of cells were as follows: CD34+, 7.73 x 10(6)/kg; and lymphocytes, 6.93 x 10(8)/kg. CONCLUSION Relatively low doses of G-CSF can mobilize sufficient numbers of AlloBSC safely and efficiently.

PURPOSE Clinical data and histologic material were retrospectively analyzed in 46 cases of previously untreated mantle cell lymphoma (MCL) to more fully characterize the clinical response pattern of these lymphomas and to determine whether growth pattern significantly affected clinical outcome. MATERIALS AND METHODS The histologic pattern was classified as diffuse (61%), nodular (13%), and mantle zone (26%) in accordance with stated criteria. RESULTS Bone marrow infiltration was detected in 69% of cases; the frequency of involvement correlated with histologic pattern, being most common in diffuse variants and least common in mantle zone variants. Other sites of extranodal involvement were observed in 50% of cases. Cyclin-D1 staining revealed nuclear positivity in 23 of 25 patients (92%) and no difference was observed between the various histologic patterns. Rearrangement at the bcl-1 major translocation cluster (MTC) was detected in seven of 21 cases, without regard for histologic pattern. Complete response rates to doxorubicin-based regimens showed a striking correlation with histologic pattern. Seventy-three percent of patients with a mantle zone pattern attained a complete response compared with only 25% of patients with a nodular pattern and 19% with a diffuse pattern. Three-year survival rates were 100%, 50%, and 55% for patients with mantle zone, nodular, and diffuse histologic patterns, respectively. CONCLUSION We conclude that (1) diffuse and nodular MCL are associated with a poor treatment response and a poor overall survival rate; (2) the mantle zone variant exhibits the clinical attributes of a low-grade lymphoma; and (3) the poor survival rates of patients with nodular and diffuse MCL suggest that these variants be classified as intermediate-grade lymphomas. However, the trend of the time to treatment failure curve does not indicate that current regimens can cure MCL.

BACKGROUND AND PURPOSE It is known that the socioeconomic status (SES) of the patient is associated with cancer survival in the United States. The purpose of this study was to determine whether the association between SES and survival is also present in Canada, a society with a comprehensive, universal, health insurance program. METHODS A population-based cancer registry was used to identify the 357,530 cases of invasive cancer diagnosed in the Canadian province of Ontario between 1982 and 1991. Information from the 1986 Canadian census was linked to the registry and used to describe the SES of the area in which each patient resided. Cox regression was used to describe the association between median household income and survival while controlling for age, sex, and the region in which the patient resided. The Cox model was fitted in a competing risk framework to assess the association between income and the probability of specific causes of death. RESULTS Lung cancer and cancers of the head and neck region were relatively more common in poor-income communities, and cancers of the breast, CNS, and testis were relatively more common in richer communities. A strong and statistically significant association between community income and survival was observed in cancers of the head and neck region, cervix, uterus, breast, prostate, bladder, and esophagus. Smaller, but significant associations were seen in cancers of the lung and rectum. No significant association between community income and survival was observed in cancers of the stomach, colon, pancreas, or ovary. Analysis of the cause of death showed that community income is associated both with the probability of death from cancer and with the probability of death from other causes. CONCLUSION Although Canada's health care system was designed to provide equitable access to equivalent standards of care, it does not prevent a difference in cancer survival between rich and poor communities.

PURPOSE To investigate the antiemetic effect and tolerability of the 5-hydroxytryptamine3(5-HT3) antagonist ondansetron plus the dopamine D2 antagonist metopimazine versus ondansetron alone in patients receiving platinum-based chemotherapy. PATIENTS AND METHODS One hundred eleven chemotherapy-naive patients who were scheduled to receive two consecutive courses of platinum-based chemotherapy were randomized between ondansetron 8 mg intravenously (IV) followed by 8 mg orally twice a day plus metopimazine 35 mg/m2 as a 24-hour continuous infusion followed by 30 mg orally four times a day for 4 days, or ondansetron plus placebo. The study used a double-blind, crossover, placebo-controlled design. RESULTS Ninety-four patients completed the crossover. Complete response (CR; no emetic episodes) was obtained on day 1 in 77.7% of the patients who received the combination versus 50.0% of those who received ondansetron alone (P = .00002), and in 51.7% versus 31.0% on days 2 to 6 (P = .0009). The overall CR (days 1 to 6) was 48.9% versus 25.3% (P = .0002). Additionally, significantly less nausea was observed with the combination on day 1 (P = .0002), days 2 to 6 (P = .0001), and days 1 to 6 (P = .00004). Patient preference was 63.6% for the combination and 13.6% for ondansetron alone; 22.7% expressed no treatment preference (P < .0001; therapeutic gain 50.0%; 95% confidence interval [CI], 31.6% to 68.4%). Adverse reactions were mild and without significant differences between the two treatments. CONCLUSION Metopimazine plus ondansetron was significantly superior to ondansetron alone, concerning all efficacy parameters assessed, in patients who received platinum-based chemotherapy.

PURPOSE To examine, in newly diagnosed patients with acute promyelocytic leukemia (APL), the prognostic significance of secondary cytogenetic changes and the relationship between such changes and the two major promyelocytic leukemia-retinoic acid receptor alpha (PML-RAR alpha) mRNA types. PATIENTS AND METHODS One hundred sixty-one patients with t(15;17)(q22;q11-12) enrolled onto Cancer and Leukemia Group B (CALGB) protocol 8461, a prospective study of cytogenetics in acute myeloid leukemia (AML), were studied. Eighty of these 161 patients were treated solely with chemotherapy and evaluated for response to treatment and survival. PML-RAR alpha mRNA type was determined using reverse transcriptase polymerase chain reaction (RT-PCR) in 56 patients. RESULTS The incidence of secondary cytogenetic abnormalities was 32%. Among 80 patients treated with chemotherapy, the presence of a secondary chromosome abnormality was associated with longer complete remission (CR) duration (median, 29.9 v 15.7 months; P = .03) and longer event-free survival (EFS) duration (median, 17.0 v 12.2 months; P = .03). There was no difference in overall survival (P = .28). In a separate group of 56 patients with both cytogenetic and molecular data, 32 had the type L PML-RAR alpha transcript (intron 6 PML breakpoint). Of these 32 patients, four (12.5%) had chromosome changes in addition to t(15;17), whereas 12 of 20 patients (60%) with the type 5 PML-RAR alpha transcript (intron 3 PML breakpoint) had secondary cytogenetic changes (P < .001). CONCLUSION (1) Secondary cytogenetic changes do not confer a poor prognosis in APL patients treated with anthracycline/cytarabine (Ara-C)-based chemotherapy; and (2) A highly significant relationship exists between the PML-RAR alpha 5 isoform (intron 3 PML genomic breakpoint) and secondary cytogenetic changes in APL.

PURPOSE The discovery of effective therapy for hairy cell leukemia (HCL) has increased the relevance of long-term outcome. We have therefore examined the incidence of second cancers. PATIENTS AND METHODS Data on 350 HCL patients was obtained from the M.D. Anderson Cancer Center Cancer Registry's computerized data base and from chart review. Standardized incidence ratios (SIRs) and standardized mortality ratios (SMRs) (observed/expected [O/E]) were calculated with the expected number determined using age, sex, and calendar-year-specific rates from the Connecticut Tumor Registry and from national mortality data, respectively. RESULTS The median age of the patients was 50 years and the median follow-up duration was 6 years. Twenty-six patients developed a second cancer at least 6 months after the HCL diagnosis (O/E ratio, 1.34; P = .08). There was no excess of malignancy among patients treated with interferon alfa (IFN-alpha; P = .27), 2-chlorodeoxyadenosine (2CDA; P = .37), or deoxycoformycin (DCF; P = .7). However, an excess of myeloma-related neoplasms (O/E, 13.04; P < .001) and lymphomas (O/E, 8.7; P = .03) was observed. Survival from the advent of systemic therapy for HCL was better than before this time (P = .0009). Nevertheless, mortality remained excessive (O/E, 6.17; P < .001), mainly because of HCL-related infections and secondary malignancy. CONCLUSION Among 350 patients with HCL, there was an increase in the number of second cancers; however, it did not reach statistical significance and was not associated with therapy. The incidence of lymphoid neoplasms was significantly higher than expected. Survival since the advent of effective systemic therapy was excellent, although excess mortality was still observed.
