RESUMO

PURPOSE: For patients with advanced gastric or gastroesophageal cancer (AGGEC) providing clinical benefit with improved palliation is highly desirable. However, a prospective evaluation of clinical benefit in AGGEC patients has never before been reported in a phase III setting. PATIENTS AND METHODS: In a multinational trial (V325), 445 patients were randomly assigned and treated with either docetaxel plus cisplatin and fluorouracil (DCF) or cisplatin and fluorouracil (CF). Clinical benefit was prospectively evaluated in this trial as a secondary end point. The primary measure for clinical benefit analysis was time to definitive worsening by one or more categories of Karnofsky performance status (KPS). Secondary clinical benefit end points included time to 5% definitive weight loss, time to definitive worsening of appetite by one grade, pain-free survival (defined as time to first appearance of pain), and time to first cancer pain-related opioid intake. Clinical benefit assessments were recorded at each clinic visit. RESULTS: Clinical benefit assessments were performed in more than 75% of patients throughout V325. DCF significantly prolonged time to definitive worsening of KPS compared with CF (median, 6.1 v 4.8 months; hazard ratio, 1.38; 95% CI, 1.08 to 1.76; log-rank P = .009). Although time to definitive weight loss and time to definitive worsening of appetite favored DCF, the results were not statistically significant. Pain-free survival and time to first cancer pain-related opioid intake were comparable. CONCLUSION: To our knowledge, V325 is the first phase III trial to report clinical benefit in AGGEC patients. Clinical benefit was assessed beyond protocol-specific chemotherapy. The addition of D to CF not only significantly improved clinical benefit but also improved quality of life, time to progression, and overall survival compared with CF.

RESUMO

PURPOSE: Therapy of patients with advanced gastric or gastroesophageal junction cancer should provide symptom relief and improve quality of life (QOL) because most patients are symptomatic at baseline. Using validated instruments, we prospectively assessed QOL (even after completion of protocol treatment) as one of the secondary end points of the V325 phase III trial. PATIENTS AND METHODS: Four hundred forty-five patients randomly received either docetaxel 75 mg/m(2) and cisplatin 75 mg/m(2) each on day 1 plus fluorouracil 750 mg/m(2)/d continuous infusion on days 1 to 5 every 3 weeks (DCF) or cisplatin 100 mg/m(2) on day 1 plus fluorouracil 1,000 mg/m(2)/d continuous infusion on days 1 to 5 every 4 weeks (CF). The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) and, where available, the EuroQOL EQ-5D questionnaire were administered every 8 weeks from baseline until progression and then every 3 months. Time to definitive deterioration of QOL parameters was analyzed. RESULTS: The proportions of patients having assessable EORTC QLQ-C30 and EQ-5D questionnaires at baseline were 86.0% and 78.7% with DCF, respectively, and 89.7% and 92.8% with CF, respectively. Time to 5% deterioration of global health status (primary end point) significantly favored DCF over CF (log-rank test, P = .01). QOL was preserved longer for patients on DCF than those on CF for all time to deterioration analyses, demonstrating the statistical superiority of DCF compared with CF. CONCLUSION: V325 represents the largest trial with the longest prospectively controlled evaluations of QOL during protocol chemotherapy and follow-up in patients with advanced gastric or gastroesophageal junction cancer. In V325, advanced gastric or gastroesophageal junction cancer patients receiving DCF not only had statistically improved overall survival and time to tumor-progression, but they also had better preservation of QOL compared with patients receiving CF.

RESUMO

PURPOSE: In the randomized, multinational phase II/III trial (V325) of untreated advanced gastric cancer patients, the phase II part selected docetaxel, cisplatin, and fluorouracil (DCF) over docetaxel and cisplatin for comparison against cisplatin and fluorouracil (CF; reference regimen) in the phase III part. PATIENTS AND METHODS: Advanced gastric cancer patients were randomly assigned to docetaxel 75 mg/m2 and cisplatin 75 mg/m2 (day 1) plus fluorouracil 750 mg/m2/d (days 1 to 5) every 3 weeks or cisplatin 100 mg/m2 (day 1) plus fluorouracil 1,000 mg/m2/d (days 1 to 5) every 4 weeks. The primary end point was time-to-progression (TTP). RESULTS: In 445 randomly assigned and treated patients (DCF = 221; CF = 224), TTP was longer with DCF versus CF (32% risk reduction; log-rank P < .001). Overall survival was longer with DCF versus CF (23% risk reduction; log-rank P = .02). Two-year survival rate was 18% with DCF and 9% with CF. Overall response rate was higher with DCF (chi2 P = .01). Grade 3 to 4 treatment-related adverse events occurred in 69% (DCF) v 59% (CF) of patients. Frequent grade 3 to 4 toxicities for DCF v CF were: neutropenia (82% v 57%), stomatitis (21% v 27%), diarrhea (19% v 8%), lethargy (19% v 14%). Complicated neutropenia was more frequent with DCF than CF (29% v 12%). CONCLUSION: Adding docetaxel to CF significantly improved TTP, survival, and response rate in gastric cancer patients, but resulted in some increase in toxicity. Incorporation of docetaxel, as in DCF or with other active drug(s), is a new therapy option for patients with untreated advanced gastric cancer.

RESUMO

PURPOSE: To evaluate whether a relationship exists between docetaxel dose and clinical response in the treatment of patients with advanced breast cancer. PATIENTS AND METHODS: Patients whose cancer had progressed after one prior chemotherapy regimen for advanced breast cancer or had recurred during or within 6 months of adjuvant chemotherapy were randomly assigned to docetaxel 60, 75, or 100 mg/m2 intravenously every 3 weeks. RESULTS: Five hundred twenty-seven patients were randomly assigned (intent to treat [ITT]), and 524 were assessable for toxicity. In the population assessable for efficacy (n = 407), logistic regression analysis showed that increasing docetaxel dose was significantly associated with higher response rate (P = .007) and improved time to progression (TTP; P = .014). In the ITT analysis, a significant dose-response relationship was observed for tumor response (P = .026) but not for TTP (P = .067). The incidences of most hematologic and nonhematologic toxicities were related to increasing dose, with grade 3 to 4 neutropenia occurring in 76.4%, 83.7%, and 93.4% and febrile neutropenia occurring in 4.7%, 7.4%, and 14.1% of patients administered the 60, 75, and 100 mg/m2 doses, respectively. One death was considered treatment related. CONCLUSION: A relationship between increasing dose of docetaxel and increased tumor response was observed across the dose range of 60 to 100 mg/m2 every 3 weeks. Toxicities were related to increasing dose. Depending on the therapy goal, any of the doses studied may be appropriate for second-line treatment of advanced breast cancer.

RESUMO

PURPOSE: To evaluate the effect on survival and quality of life of maintaining hemoglobin (Hb) in the range of 12 to 14 g/dL with epoetin alfa versus placebo in women with metastatic breast cancer (MBC) receiving first-line chemotherapy. PATIENTS AND METHODS: Eligible patients were randomly assigned to receive epoetin alfa 40,000 U once weekly or placebo for 12 months. Study drug was initiated if baseline Hb was < or = 13 g/dL or when Hb decreased to < or = 13g/dL during the study. The primary end point was 12-month overall survival (OS). RESULTS: The study drug administration was stopped early in accordance with a recommendation from the Independent Data Monitoring Committee because of higher mortality in the group treated with epoetin alfa. Enrollment had been completed, with 939 patients enrolled (epoetin alfa, n = 469; placebo, n = 470). Most patients had Hb more than 12 g/dL at baseline (median Hb, 12.8 g/dL) or during the study. From the final analysis, 12-month OS was 70% for epoetin alfa recipients and 76% for placebo recipients (P = .01). Optimal tumor response and time to disease progression were similar between groups. The reason for the difference in mortality between groups could not be determined from additional subsequent analyses involving both study data and chart review. CONCLUSION: In this trial, the use of epoetin alfa to maintain high Hb targets in women with MBC, most of whom did not have anemia at the start of treatment, was associated with decreased survival. Additional research is required to clarify the potential impact of erythropoietic agents on survival when the Hb target range is 10 to 12 g/dL.
