PURPOSE We compared prospectively the antitumor efficacy of two combination chemotherapy regimens with two different dose levels of epirubicin as first-line treatment for advanced breast cancer. PATIENTS AND METHODS One hundred forty-one fully assessable patients were randomized to receive either our intensified schedule (group A, n = 71) of epirubicin 50 mg/m2 on days 1 and 8 (every 3 weeks), or a non-intensified program (group B, n = 70) in which epirubicin was only administered on day 1. Both groups also received fluorouracil (5 FU) and cyclophosphamide 500 mg/m2 on day 1 of each course. RESULTS A statistically significant difference in response rate was observed (69% in group A v 41% in group B, P < .001) for both locally advanced (LA) and recurrent metastatic (RM) disease. Response duration (22 v 14 months, P < .01) and time to progression (TTP; 19 v 8 months, P < .02) were also significantly improved. Overall survival was similar in both groups. However, univariate and/or multivariate analyses showed a meaningful relationship between type of treatment allocated, dose-intensity (DI) of epirubicin, and response rate, as well as between TTP and survival. Ultimately, TTP and survival were also influenced by further treatment modalities, namely, hormonotherapy and chemotherapy. CONCLUSION This study validates prospectively the concept of a dose-response relationship for an anthracycline-based chemotherapy in previously untreated advanced breast cancer.

PURPOSE This trial evaluated the activity and toxicity of a prolonged schedule of low-dose, daily infusional etoposide in patients with etoposide-sensitive neoplasms. PATIENTS AND METHODS Fifteen patients (non-Hodgkin's lymphoma, n = 10; small-cell lung cancer, n = 3; germ cell neoplasm, n = 2) were treated. Ten had received etoposide previously. Etoposide 18 to 25 mg/m2/d was administered by continuous intravenous infusion for at least 21 days, or until either leukocyte count decreased to less than 2,000/microL, platelets decreased to less than 75,000/microL, or tumor progressed. Plasma etoposide levels were monitored during infusion. RESULTS Duration of therapy ranged from 21 to 560 days; uninterrupted infusion ranged from 21 to 153 days. Seven patients (47%) had an objective tumor response (six partial, one complete), with a median duration of 7 months (range, 2 to 19). Myelosuppression limited the infusion; however, only four patients had grade 4 leukopenia, and most tolerated infusions with mild to moderate leukopenia. Nine patients required RBC transfusions. Only one patient developed severe thrombocytopenia. Alopecia was universal; however, other grade 3 or 4 nonhematologic toxicities were not encountered. The mean serum etoposide concentration was 0.7 +/- 0.42 microgram/mL. Only three patients had serum etoposide levels greater than 1 microgram/mL. CONCLUSION Etoposide administered as a low-dose continuous infusion is active in etoposide-sensitive neoplasms. Myelosuppression is the major toxicity, but seems reduced when compared with other schedules. Tumor cytotoxicity was demonstrated with plasma levels ranging from 0.5 to 1.0 microgram/mL. Chronic low doses of etoposide may be superior to the standard dose and schedule and further study of this issue is warranted.

PURPOSE AND METHODS Although a high prevalence of adjustment disorders and anticipatory nausea secondary to adjuvant chemotherapy (CT) has been reported, little has been done to develop strategies to prevent these problems. A double-blind, placebo-controlled study was therefore designed to assess the usefulness of adding low-dose alprazolam (0.5 mg to 2 mg per day) to a psychologic support program including progressive relaxation training designed to prevent the aforementioned conditions. Fifty-seven women undergoing adjuvant CT for stage II primary breast cancer agreed to participate in the assessment, which was conducted at four time points: before starting CT, 6 weeks after CT, before the fourth CT, and after the fourth CT. The Hospital Anxiety and Depression Scale (HADS), Montgomery and Asberg Depression Rating Scale (MADRS), Hamilton Anxiety Scale (HAS), Revised Symptom Checklist (SCL-90-R), Morrow Assessment of Nausea and Emesis (MANE), and World Health Organization (WHO) grading of acute and subacute toxicities were used to compare the alprazolam (AA) and placebo (PA) arms of the study. RESULTS At the second evaluation, the results showed a higher rate of anticipatory nausea (18% v 0%) in the PA compared with the AA arm (P = .038). These differences were no more significant at each of the further assessments. Significant differences were found for the intake of hypnotics at each assessment visit, with the rate of hypnotic users being significantly higher in the PA (19%) compared with the AA (0%) arm at the fourth assessment (P < .05). Anxiety and depression scores of self- and observer-report were similar in the two arms. A significant relationship was found between the development of anticipatory nausea and the self-report of anxiety and depression score measured by HADS at baseline. The average HADS total score at baseline was 15.33 (SD = 6.56) for patients who developed anticipatory nausea and 11.23 (SD = 6.67) for other patients. CONCLUSION The adjunct of alprazolam to a psychologic support program delays the occurrence of anticipatory nausea and controls sleeping problems secondary to adjunct CT. Although studies are needed to improve the efficacy reported here, physicians may already consider the use of alprazolam for cancer patients undergoing CT.

PURPOSE Childrens Cancer Group (CCG) protocol 2861 was designed to test the feasibility of aggressively timed induction therapy followed by autologous or allogeneic bone marrow transplantation (BMT) as the sole postremission therapy for newly diagnosed children with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). PATIENTS AND METHODS Between April 1988 and October 1989, 142 patients were eligible for study. All patients entered received a timing-intensive five-drug induction of dexamethasone, cytarabine (Ara-C), thioguanine, etoposide, and daunorubicin (DCTER) over 4 days with a second cycle administered after 6 days of rest, irrespective of hematologic status at that time. Most patients subsequently received a second two-cycle induction course. Those who achieved remission were eligible for bone marrow ablative therapy with busulfan and cyclophosphamide, followed by 4-hydroperoxy-cyclophosphamide (4-HC)-purged autologous or allogeneic BMT rescue. RESULTS One hundred eight (76%) patients achieved remission: 19 (13%) died of complications of the leukemia and/or chemotherapy, and 15 (11%) failed to achieve remission. Seventy-four patients subsequently underwent BMT with either autologous (n = 58) or allogeneic (n = 16) rescue. For patients who received autologous rescue with 4-HC-purged grafts, the actuarial disease-free survival (DFS) rate at 3 years from the day of transplant is 51%, compared with 55% for patients who received allogeneic grafts (P = .92). At 3 years, the overall actuarial survival rate for all 142 patients entered on this study is 45%, with an event-free survival (EFS) rate of 37%. Adverse prognostic factors for outcome included an elevated WBC count or the presence of CNS leukemia at the time of AML diagnosis. CONCLUSION Results suggest that aggressively timed induction therapy followed by marrow ablation and BMT rescue with either autologous or allogeneic grafts for children with newly diagnosed AML or MDS is both feasible and effective.

PURPOSE Evaluation of high-dose chemotherapy with autologous bone marrow rescue (ABMR) in pediatric malignant gliomas. PATIENTS AND METHODS Newly diagnosed (n = 11) and recurrent (n = 2) malignant glioma patients received high-dose chemotherapy within 4 weeks of surgery; three had near total and 10 had subtotal resection/biopsy. High-dose thiotepa (300 mg/m2) and cyclophosphamide (2 g/m2) daily for 3 days were followed by ABMR; response was evaluated at day 30. At day 60, patients with at least stable disease received hyperfractionated (n = 9) or conventional external-beam radiotherapy (n = 2) preceded by local radioactive iodine 125 implantation (n = 2) or radiosurgery (n = 1). RESULTS Grade III and IV toxicities after ABMR consisted of mucositis (n = 12), cardiomyopathy (n = 1), acute abdomen (n = 1), pneumonitis (n = 2), and infection (n = 2). One complete and three partial responses were observed; the objective response rate was 31% (95% confidence interval, 9% to 61%). Seven had stable disease, one had disease progression, and one died of toxicity before response evaluation. The median overall and progression-free survival durations after combined modality therapy were 14 months (range, 4 to 30+) and 9 months (range, 0 to 30+), respectively. One patient remains progression-free at 30+ months. Radionecrosis and white matter changes occurred in three patients: one after hyperfractionated irradiation, and two after 125I implants. CONCLUSION For patients with bulky residual disease after surgery, survival with this aggressive chemotherapy and radiation regimen is not better than that reported for conventional treatment regimens.

PURPOSE To determine the prevalence of circulating t(14;18)-positive cells in patients with long-term remission after radiation therapy for stage I and II follicular lymphoma. PATIENTS AND METHODS Peripheral-blood mononuclear cells from 21 patients in continuous remission were examined by a two-step polymerase chain reaction (PCR) assay for the detection of cells carrying a t(14;18) translocation with a breakpoint within the major breakpoint region (MBR) or minor cluster region (mcr). RESULTS Follow-up duration was between 25 and 160 months, with a median of 6.5 years. Thirteen patients (62%) showed negative results on repetitive testing. Cells that were t(14;18)-positive were found in eight patients (38%), all carrying a breakpoint in the MBR. One patient relapsed in each group. CONCLUSION Circulating t(14;18)-positive cells can persist in a high percentage of follicular lymphoma patients in long-term complete remission (CR) after radiation treatment for stage I and II disease. The significance of minimal residual t(14;18)-positive cells with regard to the risk of relapse needs to be investigated in further prospective long-term studies.

PURPOSE To test the activity of a regimen of interferon alfa-2a (IFN alpha-2a) 5 x 10(6) U/m2 subcutaneously (SC) days 1 through 7 combined with leucovorin 500 mg/m2/d intravenously (IV) over 30 minutes and fluorouracil (5-FU) 370 mg/m2/d through IV push 1 hour after leucovorin days 2 through 6 in a phase II study. PATIENTS AND METHODS Forty-six patients with a good performance status (PS) with measurable colorectal cancer and no prior therapy for metastatic disease were entered. Cycles were repeated at 3-week intervals if toxicity had resolved. The 5-FU dose was increased by 15% if toxicity was mild, and decreased by 15% for grade 3 to 4 nonhematologic or grade 4 hematologic toxicity. RESULTS Three complete responses (CRs) and 21 partial responses (PRs) were seen among 44 assessable patients (54%; 95% confidence interval, 39% to 70%). A moderately strong association was noted between PS and response: PS O (n = 26), two CRs and 15 PRs (65%); PS 1 (n = 13), one CR and six PRs (54%); PS 2 (n = 5), zero CRs and zero PRs (0%; two-tailed P = .026). With a median follow-up duration of 18.8 months, the median time to treatment failure (TTF) and survival were 7.8 months and 16.3 months, respectively. Doses were escalated to 425 mg/m2/d 5-FU in 10 patients, but only four tolerated the higher dose. When expressed as the most severe degree of toxicity experienced by each patient across all cycles, grade 3 to 4 toxicity of the following types was observed; mucositis, 37%; diarrhea, 40%; rash, 7%; fatigue, 14%; granulocytopenia, 13%. Dose-limiting toxicity at 370 mg/m2/d 5-FU eventually occurred in 28 patients (61%). Twelve patients (26%) required an IFN alpha-2a dose reduction for constitutional toxicity. CONCLUSION This regimen has promising activity in advanced colorectal cancer, particularly in patients with an Eastern Cooperative Oncology Group (ECOG) PS of 0 to 1.

PURPOSE To compare chemohormonal therapy, chemotherapy alone, and hormonal therapy alone in postmenopausal patients with estrogen receptor (ER)-positive operable breast cancer and positive axillary nodes with respect to survival and disease-free survival (DFS). PATIENTS AND METHODS Eight hundred ninety-two postmenopausal women with ER-positive, node-positive breast cancer were enrolled by the Southwest Oncology Group (SWOG) from July 1979 to March 1989 and 74 by the Eastern Cooperative Oncology Group (ECOG) between June 1987 and March 1989. Patients were stratified according to number of involved nodes and type of primary surgery and randomized to receive the following: (1) tamoxifen 10 mg twice daily by mouth for 1 year; (2) cyclophosphamide 60 mg/m2/d by mouth for 1 year, methotrexate 15 mg/m2 intravenously (IV) weekly for 1 year, fluorouracil (5-FU) 400 mg/m2 IV weekly for 1 year, vincristine .625 mg/m2 IV weekly for the first 10 weeks, and prednisone during weeks 1 to 10 with doses decreasing from 30 mg/m2 to 2.5 mg/m2 (CMFVP); or (3) the combination of tamoxifen and CMFVP. RESULTS The median follow-up duration is 6.5 years, with a maximum of 12.8 years. Treatment arms are not significantly different with respect to either survival or DFS (log-rank, 2 df, P = .82 and .23, respectively). The 5-year survival rate is 77% for the tamoxifen arm, 78% for CMFVP, and 75% for the combination. No significant differences were observed in node or receptor level subsets. Severe or worse toxicity was experienced by 56% of patients on CMFVP and 61% on CMFVP plus tamoxifen, compared with 5% on tamoxifen alone. CONCLUSION CMFVP chemotherapy, either alone or in combination with tamoxifen, has not been shown to be superior to tamoxifen alone in the treatment of postmenopausal women with node-positive, ER-positive, operable breast cancer.

PURPOSE A phase I/II trial of vinorelbine (VRL) administered by continuous infusion (CIV) was conducted in advanced breast carcinoma (ABC) patients to determine the maximum-tolerated dose (MTD) and to evaluate the toxicity pattern and antitumor activity of this alternative administration schedule to the currently recommended weekly short intravenous (IV) administration. PATIENTS AND METHODS Between February 1990 and July 1991, 64 consecutive, eligible patients with ABC were treated; 33 had received one or two previous palliative chemotherapy combinations and 31 had not received chemotherapy for metastatic disease. VRL was administered, after an initial IV bolus of 8 mg/m2 on day 1, by a 4-day CIV at five different 24-hour dose levels (DLs) to be repeated every 21 or 28 days: DL1, 5.5 mg/m2; DL2, 7 mg/m2; DL3, 8 mg/m2, DL4, 9 mg/m2; and DL5, 10 mg/m2. RESULTS The limiting noncumulative toxicity was neutropenia, with the MTD established at 8 mg/m2 bolus plus 10 mg/m2/d for 4 days (total dose per cycle, 48 mg/m2). At DL3 and DL4, we observed mucositis (14% of patients; five percent of cycles > grade 2), alopecia, and asthenia. By contrast, neurotoxicity was minor. The toxicity was otherwise predictable and manageable. Pharmacokinetic data obtained at DL1 and DL3 showed a mean VRL plasma concentration of 967 +/- 331 ng/mL after the initial 8 mg/m2 IV bolus dose, which declined rapidly thereafter to reach mean steady-state levels of 12 ng/mL (n = 5) for the 30-mg/m2 dose and 8 ng/mL (n = 2) for the 40-mg/m2 dose. These levels were maintained over the 96-hour CIV. The mean residence time (MRT) was 29 +/- 7 hours (terminal half-life [t1/2], 23 hours), the total-body clearance (CL) was 24 +/- 11 L/hr/m2, and the volume of distribution at steady-state (Vss) was high at 1,832 +/- 359 L/m2. Two patients achieved a complete response (CR) and 21 a partial response (PR), for an objective response rate of 36% (95% confidence interval [Cl], 23 to 49). The median duration of response was 6 months. The median survival duration was 24 months (range, 3 to 37). A relationship between given dose-intensity and objective response rate was found, with an overall response (OR) rate of 13.3% (two of 15) for 8 to 10 mg/m2/wk, 35.4% (11 of 31) for 10 to 12 mg/m2/wk, and 55.5% (10 of 18) for 12 to 14.5 mg/m2/wk. CONCLUSION This trial, while confirming VRL activity in ABC, shows the feasability of a CIV administration schedule. A decrease of the administrated total dose per 3- to 4-week cycle to less than the weekly schedule with the same therapeutic activity suggests a better therapeutic index. The data are also suggestive of a dose-response relationship and a dose-intensity/activity correlation.

PURPOSE This study assessed whether a specific association exists between atypical nevi and germ cell tumors (GCT). METHODS A prospective comparison was performed on a cohort of 129 unselected patients with GCT and a series of 153 healthy men. Three or more of the following criteria were required for diagnosis of multiple atypical nevi: greater than 5 mm in diameter; variegated color, often speckled black/brown, with irregularly distributed pigmentation; irregular outline or indistinct border; and at least three such lesions. RESULTS Prevalences for multiple atypical nevi in patients with GCT and in healthy controls were 37% and 15%, respectively (P < .01). Two patients with these lesions also had documented malignant melanoma. In contrast, 16% of patients with GCT had a history of testicular maldescent (the most common known risk factor), compared with 5% of healthy controls (P < .01). CONCLUSION Multiple atypical nevi occur with a statistically significant increased prevalence in patients with GCT as compared with healthy controls, and constitute one of the most common known clinical associations with this malignancy. These data may be of relevance for our understanding of the biology of GCT and of malignant melanoma, in the design of screening programs for testis cancer, and in the follow-up evaluation of patients with each of these disorders.

PURPOSE The aim of the study was to investigate the role of squamous cell carcinoma antigen (SCC) in the management of patients with locally advanced cervical cancer treated by neoadjuvant chemotherapy and radical surgery. PATIENTS AND METHODS SCC assay was performed with a radioimmunoassay kit in a series of 102 patients with locally advanced cervical cancer. The values of 2.5, 5, and 7 ng/mL were used to define SCC antigen positivity. The chi 2 and Fisher's exact test and the stepwise logistic regression were used to evaluate the distribution of marker values. Analysis of survival was performed using the Kaplan and Meier test and Cox multivariate regression analysis. RESULTS SCC levels were elevated in 65%, 45%, and 32% of patients with primary tumors for cutoff values of 2.5, 5, and 7 ng/mL, respectively. SCC pretreatment levels correlated with stage, tumor volume and lymph node status. In the multivariate analysis, SCC expression proved to be an independent predictor of response to neoadjuvant chemotherapy. SCC posttreatment levels were strongly related to chemotherapy response. Moreover, the overall correlation between the clinical course of the disease and the variation of SCC levels was 83%. In patients with squamous cell tumors, survival was significantly longer in SCC-negative cases compared with SCC-positive cases (P = .04). Moreover, in patients undergoing surgery after response to neoadjuvant chemotherapy, low SCC values were associated with better prognosis (P = .02). In the multivariate analysis, parametrial involvement and SCC status proved to retain an independent prognostic value. CONCLUSION Our data show that SCC assay may provide useful information to improve the prognostic characterization and disease monitoring of patients with locally advanced cervical cancer undergoing neoadjuvant chemotherapy.
