A Case Report on Initial Experience of Lattice Radiation Therapy for Managing Massive Non-small Cell Lung Cancer and Renal Pelvic Cancer.

Lattice radiation therapy (LRT) is an advanced treatment approach specifically designed for massive tumors. It aims to deliver high-dose regions within tumors while ensuring the safety of the surrounding dose-limiting organs at risk (OAR). This case report introduces two unique clinical cases: a 63-year-old male diagnosed with a massive non-small cell lung cancer (NSCLC) tumor and a 61-year-old male with an inoperable recurrent left-sided adrenal mass intricately surrounded by dose-limiting bowel structures.

Acute toxicity of whole-pelvis IMRT in 87 patients with localized prostate cancer.

Purpose: To assess the acute toxicity profile of whole pelvis IMRT (WP-IMRT) for localized prostate cancer.

Materials: Eighty seven patients treated with definitive WP-IMRT at UTMB from May 2002 to November 2006 were retrospectively reviewed. Treatment consisted of two sequential phases, WP-IMRT to 54 Gy at 1.
