PURPOSE: We evaluated the safety and efficacy of weekly paclitaxel therapy in women with metastatic breast cancer in a phase II multicenter trial. Entry criteria were relatively liberal to reflect the heterogeneity of metastatic breast cancer in clinical practice. PATIENTS AND METHODS: Patients had histologically confirmed and measurable metastatic breast cancer. Up to two prior chemotherapy regimens for metastatic disease, including prior therapy with anthracyclines and taxanes and prior high-dose therapy, were allowed. Paclitaxel 80 mg/m2 was administered weekly for 4 weeks per 4-week cycle. RESULTS: We enrolled 212 patients; 211 were assessable for toxicity and 177 were assessable for response. Ninety percent of patients had received prior chemotherapy (adjuvant, metastatic, or both), 46% of patients had three or more involved metastatic sites, and 60% of patients had visceral-dominant disease. Responses were documented on two occasions and were independently reviewed. The overall response rate (complete plus partial response) was 21.5% (95% confidence interval, 15.4% to 27.5%), with 41.8% of patients having disease stabilization. Median time to progression was 4.7 months, and overall survival in all 212 patients enrolled was 12.8 months. Therapy was well tolerated, with a 15% incidence of grade 3/4 hematologic toxicity and a 9% incidence of grade 3 neurotoxicity; other serious toxicities were rare. The response rate and toxicity profile in the 34% of patients ≥ 65 years of age were similar to that of younger patients. CONCLUSION: Weekly paclitaxel therapy was well tolerated and demonstrated reasonable activity in this relatively heavily pretreated population with advanced disease. Further study of weekly paclitaxel in combination therapy is warranted.

To further improve the effect of high-dose chemotherapy in the treatment of locally advanced and metastatic breast cancer, we sought to develop a second active high-dose noncross-resistant regimen to use in tandem with our customary high-dose regimen of cyclophosphamide, etoposide, and cisplatin (CVP). We performed a phase II trial of high-dose mitoxantrone 30 mg/m2, etoposide 200 mg/m2 every 12 hours x 6, and thiotepa 250 mg/m2 x 3 days (MVT) in 31 patients with heavily pretreated metastatic breast cancer and one with locally advanced chemotherapy-refractory breast cancer. These patients were ineligible for high-dose CVP chemotherapy because of the amount of prior treatment and poor-response status. Of the 32 patients, 14 responded to cycle 1, did not experience any grade 4 toxicity, and received a second cycle of MVT. Overall, seven of 31 patients achieved a complete response (CR; 23%). Four of the 14, who were partial responders to the first cycle, achieved a CR after the second cycle. The overall response rate was 19 of 31 (61%) with an overall median freedom from progression of 4 to 5 months and an overall median survival of 9 months. Toxicity consisted primarily of mucositis (grade 3 or 4 in 69%). The results indicate that high-dose MVT produces significant activity, even in heavily pretreated patients. Administration of a second cycle of high-dose therapy with MVT increased the CR rate, and the morbidity and mortality from the second cycle were not greater than that for the first cycle. Because of the high incidence of grade 3 or 4 mucositis with this regimen, we are currently completing a follow-up study of high-dose mitoxantrone and thiotepa alone.

10704 Background: A previous study with weekly gemcitabine and monthly docetaxel at 100 mg/m2 yielded a 79% response rate and a median survival of 24 months. (Laufman, Ann Oncology 2001; 12:1–6). This study was designed to see if the efficacy to toxicity ratio could be improved by decreasing the docetaxel dose to 75 mg/m2. Methods: Gemcitabine and docetaxel were given to 25 patients, all of whom had received prior chemotherapy. Nine had had taxanes, more than 12 months before entry. A maximum of 6 cycles of gemcitabine 800 mg/m2 on days 1, 8 and 15 and docetaxel 75 mg/m2 on day 1 were given every 28 days. Prophylactic antibiotics were given during neutropenia. Growth factors were used for anemia, neutropenia, or for secondary neutropenic prophylaxis. Maintenance therapy consisting of gemcitabine 800 mg/m2 on days 1, 8 and 15 every 28 days was given to 12 patients, 2 of whom also received consolidation radiation. Results: A total of 122 cycles of induction therapy were given, with 14 patients receiving all 6. Dose delivery was 91.9% for docetaxel and 70.2% for gemcitabine. A total of 43 maintenance cycles were given, ranging from 1 to 12 cycles per patient. Dose delivery was 70.6%. Toxicity consisted of myelosuppression and fatigue. Grade 4 neutropenia occurred in 20 patients but was complicated by infection or fever in only 3. Five patients had grade 3 anemia and 4 had grade 3 thrombocytopenia. Other grade 3 toxicities consisted of fatigue in 8 patients, myalgia/arthralgias in 4, mucositis in 1, pneumonia in 1 and diarrhea in 1. Responses defined by RECIST criteria occurred in 12 patients (48%), including 8 of 16 taxane-naïve and 4 of 9 taxane-exposed patients. Conclusion: This regimen is active, and the most common toxicity is asymptomatic neutropenia. Sponsored by Eli Lilly and Aventis. No significant financial relationships to disclose.

The efficacy and toxicity of leucovorin 500 mg/m2 administered intravenously (IV) over 30 minutes daily for five days followed in one hour by fluorouracil (5-FU) 375 mg/m2 administered IV daily for five days, each given every 3 weeks, was assessed in 54 previously treated patients with metastatic breast cancer. An overall objective response rate of 24% was achieved (95% confidence interval, 13% to 38%), with an additional 56% of patients maintaining stable disease. Eleven of 12 patients who responded had received previous 5-FU therapy. Toxicity of this regimen included grade 3 diarrhea in 13%, grade 3 or 4 mucositis in 33%, grade 3 or 4 granulocytopenia in 65%, and grade 3 or 4 thrombocytopenia in 19%. Delay of treatment was required for hematologic toxicity in 44 patients. Thirty-eight patients required dose reductions due to toxicity. Biochemical evaluation of tumor biopsy specimens obtained from 17 patients used as their own controls with and without leucovorin was performed. These studies reveal an increased stabilization of the 5-fluorodeoxyuridylate (FdUMP)-thymidylate synthase (TS) folate ternary complex with the addition of leucovorin. There was a 71% +/- 14% occupancy or inhibition of the enzyme with the use of both 5-FU and leucovorin, v 30% +/- 13% for 5-FU alone (P2 less than .037). The percent TS bound in responding patients was substantially higher than in those patients with progressive disease. Finally, the mean total tumor TS pre-therapy in seven patients was 31 fmol/mg compared with a mean of 81 fmol/mg in these same seven patients 24 hours after therapy. This 2.6-fold increase suggests that there is an induction of the enzyme, TS, with 5-FU treatment.

Purpose Cisplatin and gemcitabine have single-agent activity in metastatic breast cancer, and preclinical data support synergy of the combination. Two parallel, phase II trials were conducted to evaluate the response rate, response duration, and toxicities of the combination. Genetic polymorphisms were analyzed for correlation with outcomes. Patients and Methods Eligible women had measurable disease and heavily or minimally pretreated metastatic breast cancer. The heavily pretreated protocol required prior anthracycline and taxane therapy; cisplatin as part of high-dose therapy was allowed. All patients received cisplatin 25 mg/m2 on days 1 through 4 and gemcitabine 1,000 mg/m2 on days 2 and 8 of a 21-day cycle with prophylactic granulocyte colony-stimulating factor in the heavily pretreated group. Sera from a subset of patients were evaluated by polymerase chain reaction restriction fragment length polymorphism for polymorphisms in 10 genes of interest. Results Of 136 women enrolled, 74 were heavily pretreated. Both protocols accrued to their two-stage design. The response rate for both the heavily and minimally pretreated cohorts was 26%, and the median durations of response were 5.3 and 5.9 months, respectively. In a multivariate analysis, hormone receptor–negative disease was associated with a higher response rate. The most common grades 3 or 4 toxicities were thrombocytopenia (71%), neutropenia (66%), and anemia (38%). In a subset of 55 patients, the xeroderma pigmentosum group D (XPD)–751, x-ray cross-complementing group 3 (XRCC3) and cytidine deaminase polymorphisms were significantly associated with clinical outcomes. Conclusion Combination cisplatin and gemcitabine is active in metastatic breast cancer regardless of prior therapy. Genetic polymorphisms may tailor which patients benefit from this regimen.

PurposeTo evaluate trastuzumab (H) and docetaxel (T) with or without capecitabine (X) as first-line combination therapy for human epidermal growth factor receptor 2 (HER2) -positive advanced breast cancer.Patients and MethodsPatients with HER2-positive locally advanced or metastatic breast cancer were randomly assigned to H (8 mg/kg loading; 6 mg/kg every 3 weeks) plus T (75 mg/m2in HTX arm, 100 mg/m2in HT arm, every 3 weeks) with or without X (950 mg/m2twice per day on days 1 to 14 every 3 weeks). The primary end point was overall response rate (ORR).ResultsIn 222 patients, median follow-up was approximately 24 months. ORR was high with both regimens (70.5% with HTX; 72.7% with HT; P = .717); complete response rate was 23.2% with HTX compared with 16.4% with HT. HTX demonstrated significantly longer progression-free survival: median 17.9 months compared with 12.8 months with HT (hazard ratio, 0.72; P = .045), which translates to a gain of around 5 months. Two-year survival probability was 75% with HTX compared with 66% with HT. Febrile neutropenia (27% v 15%) and grade 3/4 neutropenia (77% v 54%) incidences were higher with HT than HTX. Treatment-related grade 3 hand-foot syndrome (17% v < 1%) and grade 3/4 diarrhea (11% v 4%) occurred more commonly with HTX than HT. One case of congestive heart failure occurred in each arm.ConclusionHTX is an effective and feasible first-line therapy for HER2-positive locally advanced or metastatic breast cancer, although it should be reserved for patients with good performance status who are not receiving long-term steroids.

PURPOSE To evaluate the efficacy and toxicity of paclitaxel administered as a 1-hour infusion on weekly basis, without interruption, to patients with metastatic breast cancer who had received prior therapy. PATIENTS AND METHODS Thirty patients with metastatic breast cancer received sustained weekly paclitaxel therapy at an initial dose of 100 mg/m2 until disease progression. Prior therapy included adjuvant only (n=17), metastatic only (n=7), or both (n=6). Eighteen patients had received prior anthracycline therapy, 12 of whom had demonstrated progression of disease within 12 months of it. All patients were assessable for efficacy; 29 patients were assessable for toxicity. Pharmacokinetic studies of paclitaxel were also performed. RESULTS A total of 469 weekly paclitaxel infusions were administered to 30 patients (median, 14 infusions/patient). The median delivered dose-intensity was 91 mg/m2/wk (range, 80 to 108). The overall response rate was 53% (95% confidence interval [CI], 34% to 72%), with 10% complete responses (CRs) and 43% partial responses (PRs). Median response duration was 7.5 months (range, 2 to 11+). Responses were observed in nine of 18 (50%) patients with prior anthracycline therapy, including six of 12 (50%) with disease progression on anthracycline within 1 year (three of four within 6 months). Therapy was well tolerated and remarkable for a lack of overall and cumulative myelosuppression. Grade 3/4 neutropenia occurred in four patients; febrile neutropenia was not observed. Peripheral neuropathy prohibited dose escalation above 100 mg/m2, and grade 3 neuropathy was observed in two of 21 patients at < or = 100 mg/m2. CONCLUSION Weekly paclitaxel therapy is active and well tolerated in patients with metastatic breast cancer. Weekly therapy should be considered as a current clinical option for these patients and should be incorporated into future comparative clinical trials.
