Introduction:

Sampling or complete lymphadenectomy are techniques for accessing the mediastinum. Their assessment allows to define the approach in patients with lung cancer.

Objective:

To determine survival outcomes in ill patients with resectable lesions due to lung cancer after complete or sampling lymphadenectomies.

Methods:

A longitudinal case series study was performed in 118 patients with resectable lesions of nonsmall-cell lung cancer. All the patients were divided into two groups. The 73 ill patients from group A underwent sampling lymphadenectomy (1996-2010), while the 45 patients from group B underwent complete lymphadenectomy (2011-2019). Complications and five-year survival were analyzed.

Results:

A higher amount of nodes were resected per patient and per region in complete lymphadenectomy, with a survival of 50.6%, higher than the 39.7% corresponding to the sampling group. No complications inherent to the surgical techniques were collected.

Conclusions:

Patients operated on by resection and complete lymphadenectomy had higher survival figures than those operated on by resection and sampling lymphadenectomy.
