[Pulmonary segmentectomy for tumour].

Background: An analysis of outcome data of pulmonary segmentectomy focused on local efficacy in primary non small cell lung cancer and true or seeming lung metastasis.

Patients And Methods: Miscellaneous series of twenty patients treated with classical open procedure involving individuals with primary or metachronous non small cell lung cancer, solitary pulmonary metastasis of extrapulmonary cancer and/or benign pulmonary lesions, lung metastasis mimicing. Thirteen patients after segmentectomy because of malignancy are separated into a group of 7 cases with NSCLC up to 20 mm in diameter, and a group of 6 persons with solitary pulmonary opacity up to 38 mm treated previously surgically for extrapulmonary cancer. Both without enlargement of hilar and/or mediastinal lymphatics proven on preoperative CT imaging. Third part of the group collects benign pulmonary lesions: chondrohamartoma, pneumonitis and pulmonary infarct. Persons involved through a ten years period are followed up at 3 (4)-months intervals.

Results: No perioperative and thirty day mortality was registered. Six cases of distant recurrence were recorded, three in NSCLC and three in extrapulmonary cancer patients. Five patients died within the follow-up period, three of them through the general progression of the oncological disease. Two deaths were non-cancer related. One R1 disease was discovered in a patient with primary lung adenocarcinoma. No local recurrence was recorded in both cancer series with median age of 63 yrs (range 45-79 yrs) and median duration of follow up 35 months.

Conclusion: Lung segmentectomy seems to accomplish local control of early stage non small cell lung cancer and pulmonary metastasis of extrapulmonary cancer in selected patients.
