A closer look at the conventional Winston-Lutz test: Analysis in terms of dose.

Aim: To investigate whether the target-isocenter deviations reported by a conventional Winston-Lutz (WL) test actually reflect the shifts of the measured prescription isodose line with respect to the target.

Background: A conventional WL test uses a metallic ball as a target that aims at several fields. But this test does not report information on the accuracy of the delivery in terms of dose.

[Combined radiochemotherapy in localised small-cell lung cancer. Concurrent treatment protocols?].

Purpose: We retrospectively reviewed our Institution's database to investigate the outcome and impact of combined radiochemotherapy (RT/CT; concomitant or in sequence) in localised small-cell lung cancer (L-SCLC).

Material And Methods: Between January 1995 to November 1999, 79 patients with L-SCLC received combined RT/CT at our Institution. RT was delivered concurrently or sequentially following the CT.
