Hyperthermic intrapleural chemotherapy: an update.

The safety and efficacy of hyperthermic intrathoracic chemotherapy (HITHOC) as an adjunct to cytoreductive surgery (CRS) in pleural malignancies has been well demonstrated. This is most often described in cases of mesothelioma, thymoma, or other secondary pleural metastases. The utilization of a direct cytotoxic agent with increased penetration secondary to a hyperthermic environment is especially beneficial in pleural malignancy as a microscopic resection remains immensely challenging. Despite favorable outcomes with a limited associated risk profile, there persists a variety in utilization and technique of HITHOC described in current literature. National Comprehensive Cancer Network (NCCN) guidelines state that though intraoperative adjuvant therapies such as HITHOC have been studied, they remain of unclear benefit and definitive recommendations do not currently exist. This ambiguity limits the standardization of HITHOC, thus hindering its further application in a patient population with exceedingly poor outcomes within current guideline-based therapy. As the prevalence of pleural malignancies necessitating CRS with adjuvant HITHOC remains quite low, we believe a task force initiative to further investigate the role of HITHOC in surgical management of pleural malignancies would enable wider utility of this promising technique. Additionally, we propose that the creation of a pleural cancer index could aid in standardization of HITHOC in those with pleural malignancy.
