The preferred treatment for locally aggressive lung cancers is triple modality therapy with concurrent and induction chemotherapy with radiation therapy followed by surgery. Patients with locally advanced T4 Pancoast tumors with spine involvement, without mediastinal N2 lymph node involvement and without distant metastases, are appropriate candidates for complete resection with subsequent spine reconstruction. This review addresses the questions of whether triple modality therapy with complete en bloc resection of locally advanced Pancoast tumors offers an advantage in terms of overall survival and complication rates compared with other therapeutic modalities or therapies with incomplete resection.
Methods
A comprehensive literature search was conducted using common medical databases. Inclusion and exclusion criteria for the articles were prospectively defined. The articles were independently reviewed and a consensus decision was made about each article. Selected papers were graded by level of evidence.
Results
A total of 1,001 abstracts and 93 articles fulfilled the criteria; from these studies, 14 were included in this systematic review. No level 1 study was found in this search. Four level 2 studies and 10 level 3 retrospective case series were found. The overall 5-year survival rate reported in these studies ranged from 37% to 59% and the mortality rate ranged from 0% to 6.9%.
Conclusions
Evidence suggests that triple modality therapy with complete resection of locally advanced Pancoast tumors with involvement of the spine offers an advantage over other therapeutic modalities or therapies with incomplete resections.
