ABSTRACT
UNLABELLED Is it possible to choose between limited lymph node sampling and systematic lymphadenectomy from the distribution of sentinel lymph nodes in patients with small lung cancer less than 2 cm in diameter? METHODS:
Twenty-four patients with cN0M0 lung cancer less than 2 cm in diameter were enrolled. A radioisotope tracer (Tc-99 m tin colloid or phyphate) was injected in the vicinity of the tumor before surgery under computed tomography (CT) guidance. The radioactivity of each resected lymph node was measured separately with a hand-held gamma probe after complete tumor resection. Sentinel nodes were identified and the accuracy of sentinel node mapping was examined.RESULTS:
Successful radionuclide migration occurred in 20 of the 24 patients (83.3%). There were 21 N0 patients and 3 N-positive patients. There was no false-negative case, so the sensitivity and the specificity was 100%. The lobar lymph nodes were identified as sentinel nodes more frequently than other lymph nodes.CONCLUSION:
The sentinel node concept is valid in patients with small lung cancer less than 2 cm in diameter. We believe that, if sentinel nodes are identified, sentinel node mapping can allow the accurate intraoperative diagnosis of pathological N0 status in patients with small peripheral lung cancer.
