Patients with morphologically similar, advanced-stage tumors display a broad range of clinical outcomes. Features currently used for prognosis and chemotherapy decision are clinicopathological and include patient’s age, performance status, FIGO stage, histological

tumor grade and subtype, initial surgery Selleckchem SC79 results and response to chemotherapy. These factors were not incorporated in the initial design of randomized studies although they might be associated with different responses to HDC. The present study is a retrospective comparative survival analysis, including subsets analysis based on usual clinicopathological features. A survival comparison was done between 103 patients with AOC treated by surgery plus platinum/taxane-based conventional

chemotherapy alone (CCA) and 60 patients who received the same treatment plus HDC and autologous HSCS. Methods Population description Patients were selected in our institutional “Ovarian Cancer” database, which included all ovarian cancer patients treated at the Institut Paoli-Calmettes (Marseilles, France) since 1995. Eligible patients were aged between 18 and 64 years and had histologically proven invasive ovarian carcinoma with advanced buy CA4P (FIGO stage IIIc) or metastatic (FIGO stage IV) disease at diagnosis. All patients were treated using a standard multimodal approach including surgery and platinum/taxane-based chemotherapy. In the “HDC” group, patients also received HDC with HSCS. Hematological rescue consisted of autologous hematopoietic stem cells collected from peripheral blood. After completion of treatment, patients were evaluated at 3-month intervals for the first 2 years and at 6-month intervals thereafter. Evaluations included clinical examination and blood tests with CA125 assessment. CT scan evaluations were performed every 6 months for the first 5 years and yearly thereafter. Other examinations were performed only when indicated. The study was Temsirolimus manufacturer approved by our institutional

review board. According to the French law, since it was a retrospective study without biological research and without therapy modification, Palbociclib in vitro no personal consent was required. Statistical analysis Differences in patient characteristics between the two chemotherapy groups (with vs. without HDC) were tested by the Fisher’s exact test (categorical variables) or the Student’s t-test (continuous variables). Tested parameters were age at diagnosis (with a threshold at 50 years old), performance status, FIGO stage, histological subtype (serous vs. others), histological grade according to Silverberg classification (grade 1 and 2 were pooled), presence of residual disease after surgery, presence of a clinical remission after platinum/taxane-based therapy (according to clinical and radiological examinations), CA125 normalization after platinum/taxane-based therapy. Progression-free survival (PFS) was calculated from the date of diagnosis until date of first disease progression.
