From 1979 to 1987, 907 patients with non-oat cell carcinoma of the lung
were subjected to thoracotomy: of these, 685 (75.5%) underwent radical
resection of the lung tumour. The 230 stage IIIa patients were studied in
this paper. These were divided into three groups. First group: 93 patients
with only local parietal or mediastinal spread without involvement of the
mediastinal lymph nodes (T3N0-1M0); the 5-year survival of this group was
35% (44.1% when the ribs and muscles were not affected). A second group of
118 patients had tumour spreading to the mediastinal lymph nodes, but
without local involvement (T1-2N2M0): this group had a 5-year survival of
22.3%. The 5-year survival was better in patients without metastases in the
subcarinal lymph nodes than in patients with them (23.76% versus 12.89%).
Skipping of lymphatic levels was frequent: 37% of patients with metastasis
to mediastinal lymph nodes did not have metastases in the lymph nodes of
the lung; 10% of tumours removed by lobectomy had metastases in the lymph
nodes of the residual lobe. The third group with parietal and lymphatic
mediastinal invasion (T3N2M0) had a poor survival (13.5% at 5 years). The
author concludes that it is possible to achieve an acceptable 5-year
survival in selected cases with metastasis to mediastinal lymph nodes: when
the CT scan demonstrated mediastinal lymph nodes larger than 1.5 cm,
mediastinoscopy was carried out and, if positive, the patient was judged
inoperable.
