Impact of body mass index (BMI) on the prognosis of high-risk early breast cancer (EBC) patients treated with adjuvant chemotherapy.

The association between obesity and prognosis in early breast cancer (EBC) is unclear, especially when aggressive phenotypes are considered. We evaluated the influence of BMI on the prognosis of women with high-risk EBC enrolled in a phase III trial of adjuvant chemotherapy (CT). The association was assessed in 1066 patients with rapidly proliferating tumors, randomized to receive adjuvant CT with or without anthracyclines.

Time to initiation of adjuvant chemotherapy in patients with rapidly proliferating early breast cancer.

Aim: To evaluate the optimal time interval from definitive surgery to commencing chemotherapy in early breast cancer (EBC).

Patients And Methods: The relationship between time to initiation of adjuvant chemotherapy (TTC), calculated in weeks, and disease-free (DFS) or overall survival (OS), was assessed in 921 EBC patients with rapidly proliferating tumours (thymidine labelling index >3% or G3 or Ki67 >20%), randomised in a phase III clinical trial (NCT01031030) to receive chemotherapy with or without anthracyclines (epirubicin→cyclophosphamide, methotrexate and fluorouracil (CMF) versus CMF→epirubicin versus CMF). DFS, OS and 95% confidence intervals (95% confidence interval (CI)) were calculated by the Kaplan-Meier method.

Post-relapse survival in patients with Ewing sarcoma.

Background: Post-relapse survival (PRS) was evaluated in patients with Ewing sarcoma (EWS) enrolled in chemotherapy protocols based on the use of high-dose chemotherapy with busulfan and melfalan (HDT) as a first-line consolidation treatment in high-risk patients.

Procedure: EWS patients enrolled in ISG/SSG III and IV trials who relapsed after complete remission were included in the analysis. At recurrence, chemotherapy based on high-dose ifosfamide was foreseen, and patients who responded but had not received HDT underwent consolidation therapy with HDT.

Benefit from anthracyclines in relation to biological profiles in early breast cancer.

There are no validated predictors of benefit from anthracyclines. We compared cyclophosphamide, methotrexate, 5-fluorouracil (CMF), and epirubicin in different sequences with CMF alone in a phase III trial on operable breast cancers. Outcomes were analyzed in relation to tumor biological profiles to identify potential predictors of the efficacy of different treatments/drug combinations.

High-dose chemotherapy with stem cell rescue in the primary treatment of metastatic and pelvic osteosarcoma: final results of the ISG/SSG II study.

Background: Patients with metastatic osteosarcoma at diagnosis or axial primary tumors have a poor prognosis. The aim of the study was to evaluate the feasibility and efficacy of intensified treatment with high-dose chemotherapy (HDCT) and stem cell rescue in this group.

Methods: From May 1996 to August 2004, 71 patients were included in a Scandinavian-Italian single arm phase II study.
