Randomized Controlled Trial Clinical Trial
Identification of prognostic subgroups among patients with metastatic 'IGCCCG poor-prognosis' germ-cell cancer: an explorative analysis using cart modeling.
The IGCCCG classification has identified three prognostic groups of patients with metastatic germ-cell tumors. 'Poor prognosis' is based on primary tumor localization, the presence of visceral metastases, and/or high tumor-marker levels. The overall survival rate of these patients is about 45%-55%. The present analysis attempts to identify subsets of patients with a more or less favorable outcome among the 'poor-prognosis' group. ⋯ Different prognostic subsets of patients can be identified among the group of 'poor-prognosis' GCT patients. The CART analysis model results in a hierarchy of prognostic factors which may allow to more precisely estimate the individual patient's prognosis. Identifying subgroups of 'very poor-prognosis' among 'poor-prognosis' patients may allow to test for new treatment strategies in selected subgroups.

Clinical Trial
Octreotide acetate long-acting release in patients with metastatic neuroendocrine tumors pretreated with lanreotide.
In the present study we investigated the efficacy and tolerability of i.m. octreotide acetate (octreotide LAR) in patients with metastatic neuroendocrine tumors (NETs) previously treated and failed on i.m. lanreotide. ⋯ Octreotide LAR 20 mg shows significant efficacy in terms of objective response rate (PR + SD), biochemical and symptomatic control in patients with metastatic NETs of the GEP system pretreated and progressing on slow release lanreotide.
