Cisplatin plus gemcitabine on days 1 and 4 every 21 days for solid tumors: result of a dose-intensity study.

Background: Three and 4-week cisplatin-gemcitabine schedules have shown similar dose-intensity (DI) and activity in non-small-cell lung cancer (NSCLC). The 3-week schedule is generally preferred because it enables better treatment compliance. To improve DI and compliance further, we delivered gemcitabine plus cisplatin over 4 days every 21 days.

Endometrial evaluation with transvaginal ultrasound during hormone therapy: a prospective multicenter study.

Objective: To assess the value of endometrial thickness as a marker of endometrial abnormality risk during hormone therapy (HT) and to study the correlation between abnormal bleeding and abnormal endometrial histology in patients with thick endometrium.

Design: Prospective multicenter study.

Setting: University and general hospitals outpatient centers.

Cisplatin versus carboplatin in combination with mitomycin and vinblastine in advanced non small cell lung cancer. A multicenter, randomized phase III trial.

Background: In advanced not selected NSCLC chemotherapy achieved an advantage of approximately 1-2 months on median survival versus best supportive care. Chemotherapy seems to improve symptoms control, even if randomised studies with quality of life as first endpoint are lacking and often chemotherapy toxicity compromises the frail cost/benefit ratio. The aim of the present study is to evaluate the impact on QoL, substituting cisplatin, a pivot drug in NSCLC therapy, with carboplatin, an analogue with an improved toxicity profile.

Cerebrospinal fluid HIV-1 RNA levels: correlation with HIV encephalitis.

Objective: Neuropathological abnormalities induced by HIV-1 are not always predictable on the basis of the presence of HIV-related neurological symptoms. HIV-1 RNA load was measured in the cerebrospinal fluid (CSF) of HIV-infected patients to verify whether it could be a marker of HIV-induced neuropathology.

Design And Methods: Histopathological and immunohistochemical examination of the brain for HIV-1 p24 antigen was performed in 50 HIV-infected patients with neurological symptoms; patients were defined as having HIV encephalitis in the presence of HIV-related lesions or HIV-1 p24 antigen-positive cells.
