Prognosis of patients with adenocarcinoma of the lung and mediastinal lymph node metastases undergoing pulmonary resection.

Of 57 patients who were operated on for adenocarcinoma of the lung during the period 1966-1970, 18 with mediastinal lymph node metastases successfully underwent potentially curative pulmonary resection combined with complete mediastinal lymph node dissection. The 5-year survival rate was nil. In light of this poor outlook, we do not recommend surgery as the primary treatment of choice in patients with adenocarcinoma of the lung and known mediastinal lymph node metastases.

Resectional surgery in the treatment of primary carcinoma of the lung with mediastinal lymph node metastases.

Between 1966 and 1970 we reviewed 46 consecutive patients undergoing resection for primary carcinoma of the lung, in whom mediastinal lymph node metastases were found at operation. There was one operative death. Five of the remaining 45 patients survived five years--one of 10 cases of large cell carcinoma, one of 19 cases of adenocarcinoma, and three of 12 cases of epidermoid carcinoma.

The influence of cell type and lymph node metastases on survival of patients with carcinoma of the lung undergoing thoracotomy.

We studied 202 cases of bronchogenic carcinoma treated surgically between January 1, 1966 and December 31, 1970. Over all, adenocarcinoma was the most common cell type (36.1 per cent).
