Malignant Pleural Mesothelioma Nodal Status: Where Are We at?

J Clin Med. 2021 Nov 5;10(21):5177. doi: 10.3390/jcm10215177.

Abstract

Due to the lack of both prospective trial and high-volume retrospective studies, the management of clinical N+ malignant pleural mesothelioma (MPM) patients remains highly debated. Node positive patients show poor survival compared with node-negative ones; thus, lymph node staging appears crucial in determining treatment strategy. Notwithstanding the improvement in pre-treatment staging and the update on lymph node classification in the 8th edition of TNM, several open controversies remain on N parameter. How should we stage suspected N+ patients? How should we treat node positive patients? Which is the definition of a "resectable patient"? Is the site or the number the main prognostic factor for node positive patients? The aim of our narrative review is to analyse the existing relevant literature on lymph node status in MPM.

Keywords: malignant pleura mesothelioma; node positive MPM; prognostic factors; staging; surgery.
