Long-term follow-up using testicle-sparing surgery for Leydig cell tumor.

Background: Our objective was to perform a long-term evaluation of conservative surgical treatment of Leydig cell tumors.

Patients And Methods: A multicenter retrospective clinical study was performed at 6 European centers. Case files of all patients diagnosed with Leydig cell tumor and treated with conservative surgery were examined.

A randomized phase IIb presurgical study of finasteride vs. low-dose flutamide vs. placebo in men with prostate cancer. Efficacy monitored by karyometry.

Objective: Presurgical, window of opportunity trials have been proposed as a model to assess the activity of preventive and therapeutic interventions in a cost-effective manner in prostate cancer (CaP). The aim of the study was to explore karyometry as a method for monitoring the efficacy of intervention with preventive agents in patients with CaP.

Materials And Methods: The material used in this investigation was from the 2F study, i.

Image-guided robotic radiosurgery as salvage therapy for locally recurrent prostate cancer after external beam irradiation: retrospective feasibility study on six cases.

Aims And Background: Technological advances in treatment planning and execution are providing new potential opportunities in the treatment of recurrent prostate cancer. This study was conducted to evaluate the feasibility and safety of reirradiation with image-guided radiosurgery using CyberKnife, a robotic arm-driven compact linear accelerator, for intraprostatic recurrence after external beam radiotherapy (EBRT).

Methods: Between September 2007 and May 2008, 6 patients diagnosed with locally recurrent prostate cancer after EBRT were treated using the CyberKnife system.

Conservative surgical therapy for leydig cell tumor.

Purpose: We performed a long-term evaluation of conservative surgical treatment of benign Leydig cell tumor.

Materials And Methods: A multicenter retrospective clinical study was performed at 6 European centers. Case files of all patients diagnosed with Leydig cell tumor and treated with conservative surgery were examined.

Dose distribution in 3-dimensional conformal radiotherapy for prostate cancer: comparison of two treatment techniques (six coplanar fields and two dynamic arcs).

Purpose: To compare dose distribution for two techniques of 3-dimensional conformal radiotherapy (RT): 6-field technique (6F) and 2-dynamic arc therapy (2DA).

Methods And Materials: Thirty nonmetastatic prostate cancer patients were included. In each patient, two treatment plans were prepared: with six coplanar fields (45 degrees , 90 degrees , 135 degrees , 225 degrees , 270 degrees , 315 degrees ) and with two dynamic lateral 100 degrees -wide arcs (40-140 degrees , 220-320 degrees ).
