A Risk-Adapted Approach to Patients with Stage I Seminoma according to the Status of Rete Testis: The Fourth Spanish Germ Cell Cancer Group Study.

Objective: The aim of this study was to assess a risk-adapted strategy for stage I seminoma guided by the presence of rete testis invasion.

Methods: Between January 2013 and December 2015, a total of 135 consecutive patients with stage I seminoma from 18 Spanish tertiary hospitals were included in a prospective multicenter study. Median patient age was 38 years (range 22-60).

Randomized Phase II Study of Trabectedin and Doxorubicin Compared With Doxorubicin Alone as First-Line Treatment in Patients With Advanced Soft Tissue Sarcomas: A Spanish Group for Research on Sarcoma Study.

Purpose: Doxorubicin and trabectedin are considered active drugs in soft tissue sarcoma (STS). The combination of both drugs was hypothesized to be advantageous and safe on the basis of preclinical evidence and a previous phase I trial, respectively. The aim of this study was to compare the clinical outcome of trabectedin plus doxorubicin with doxorubicin as first-line treatment of advanced STS patients.
