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

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. Both patients underwent LRT to enhance tumor control and maintain less toxicity. Notably, both patients displayed a significant tumor volume reduction accompanied by minimal adverse effects during the 12-month follow-up period. While these initial results suggest that LRT may be effective and safe for treating large tumors, further investigation through exhaustive research and multicenter trials is necessary to fully understand and determine the specifics of lattice radiation therapy techniques.
