ABSTRACT
BACKGROUND: Survival of patients suffering from cerebral metastases (CM) is limited. Identification of patients with a high risk for CM is warranted to adjust follow-up care and to evaluate preventive strategies. PATIENTS AND METHODS: Exploratory analysis of disease-specific parameter in patients with metastatic breast cancer (MBC) treated between 1998 and 2008 using cumulative incidences and Fine and Grays' multivariable regression analyses. RESULTS: After a median follow-up of 4.0 years, 66 patients (10.5%) developed CM. The estimated probability for CM was 5%, 12% and 15% at 1, 5 and 10 years; in contrast, the probability of death without CM was 21%, 61% and 76%, respectively. A small tumor size, ER status, ductal histology, lung and lymph node metastases, human epidermal growth factor receptor 2 positive (HER2+) tumors, younger age and M0 were associated with CM in univariate analyses, the latter three being risk factors in the multivariable model. Survival was shortened in patient developing CM (24.0 months) compared with patients with no CM (33.6 months) in the course of MBC. CONCLUSION: Young patients, primary with non-metastatic disease and HER2+ tumors, have a high risk to develop CM in MBC. Survival of patients developing CM in the course of MBC is impaired compared with patients without CM.

BACKGROUND: Almost all retrospective trials pointed out that a benefit of surgery for recurrent ovarian cancer may be limited to patients in whom a macroscopic complete resection could be achieved. Peritoneal carcinomatosis has been reported to be either a negative predictor for resectability or a negative prognostic factor, or both. The role of peritoneal carcinomatosis in a multicenter trial was investigated. METHODS: Exploratory analysis of the DESKTOP I trial (multicenter trial of patients undergoing surgery for recurrent ovarian cancer, 2000 to 2003). RESULTS: A total of 125 patients (50%) who underwent surgery for recurrent ovarian cancer had peritoneal carcinomatosis. Univariate analyses showed worse overall survival for patients with peritoneal carcinomatosis compared with patients without carcinomatosis (P < .0001). Patients with and without peritoneal carcinomatosis had a complete resection rate of 26% and 74%, respectively (P < .0001). This corresponded with the observation that patients with complete resection had a better prognosis than those with minimal residual disease of 1 to 5 mm, which commonly reflects peritoneal carcinomatosis (P = .0002). However, patients who underwent complete resection, despite peritoneal carcinomatosis, had a 2-year survival rate of 77%, which was similar to the 2-year survival rate of patients with completely debulked disease who did not have peritoneal carcinomatosis (81%) (P = .96). Analysis of prognostic factors did not show any independent effect of peritoneal carcinomatosis on survival in patients who underwent complete resection. CONCLUSIONS: Peritoneal carcinomatosis was a negative predictor for complete resection but had no effect on prognosis if complete resection could be achieved. Improving surgical skills might be one step to increase the proportion of patients who might benefit from surgery for recurrent disease.

PURPOSE: A multicenter, nonrandomized, phase II study was initiated to evaluate the tolerability, toxicity, and activity of paclitaxel, carboplatin, and gemcitabine combination in previously untreated ovarian cancer. PATIENTS AND METHODS: Chemonaive patients who had radical debulking surgery for primary epithelial ovarian cancer International Federation of Gynecology and Obstetrics (FIGO) IC-IV received sequentially paclitaxel 175 mg/m(2), carboplatin AUC 5, and gemcitabine 800 mg/m(2) on day 1 and gemcitabine 800 mg/m(2) on day 8, every 3 weeks. RESULTS: From October 2001 to July 2002, 55 patients were treated and evaluated. Main toxicities were hematological with NCI-CTC grade 3/4 anemia 12.7%, leukopenia 70.9%, neutropenia 76.3%, and thrombocytopenia 45.5. However, febrile neutropenia occurred only in 1.8%. Grade 3/4 nonhematological toxicities were rare and occurred in less than 10% of patients. Toxicity-induced treatment delays occurred in 3.1% of cycles and resulted in early treatment cessation in four patients. Dose intensity reached 90.8% for carboplatin and paclitaxel, and 73.3% for gemcitabine. Objective response was observed in 10 of 14 patients with measurable disease. CONCLUSIONS: The triplet combination of paclitaxel-carboplatin-gemcitabine is feasible and active, with manageable hematological toxicity and no unexpected nonhematological toxicity. This regimen has proceeded to phase III evaluation.

This study was designed to evaluate the cardiac safety of the combined treatment of HER2-positive metastatic breast cancer patients with trastuzumab (Herceptin) plus epirubicin and cyclophosphamide (EC) in comparison with EC alone in HER2-negative metastatic breast cancer patients. Patients included those with metastatic breast cancer without any prior anti-HER2 treatment, anthracycline therapy, or any other chemotherapy for metastatic disease. This was a nonrandomized, prospective, dose-escalating, multicenter, open-label, phase I study in Germany. A control group of 23 patients received EC 90/600 mg/m2 3-weekly for six cycles (EC90 alone). A total of 26 HER2-positive patients were treated with trastuzumab, or H (2 mg/kg weekly after an initial loading dose of 4 mg/kg), and EC 60/600 mg/m2 3-weekly for six cycles (EC60+H); another 25 HER2-positive patients received H and EC 90/600 mg/m2 3-weekly for six cycles. Asymptomatic reductions in left ventricular ejection fraction (LVEF) of more than 10% points were detected in 12 patients (48%) treated with EC60+H and in 14 patients (56%) treated with EC90+H vs 6 patients (26%) in the EC90 alone cohort. LVEF decreases to <50% occurred in one patient in the EC60+H cohort and in two patients in the EC90+H cohort during the H monotherapy. No cardiac event occurred in the cohort with EC90 alone. The overall response rates for EC60+H and EC90+H were >60%, vs 26% for EC90 alone. The interim results of this study approve the cardiac safety of the combination of H with EC, with low risk of cardiac toxicity. The combination regimen revealed promising efficacy.
