[The feasibility of a limited operation for primary lung cancer].
We reviewed 33 patients who underwent a limited operation for primary lung cancer between 1980 and 1998. These cases were divided into three groups; a poor risk group consisting of 18 patients who had a high risk such as pulmonary or cardiac dysfunction and who underwent partial resection of a lung, a reduction group consisting of 9 patients who had advanced lung cancer or uncontrolled cancer of an organ other than the lung and who underwent partial resection, and an active limited operation group consisting of 6 patients who underwent segmentectomy with lymphoadenectomy for the treatment of early lung cancer. The 1 and 3-year survival rates in the poor risk group, reduction group and active limited operation group were 73.9, 60.0, 100%, and 63.4, 0.0, 100%, respectively. The results of limited operations performed for poor risk cases were satisfactory in terms of both functional state and prognosis. Limited operations performed to reduce tumor in advanced lung cancer cases did not improve the prognosis. Although an active limited operation for a case of early lung cancer remains controversial with respect to indication, it is thought that this operation is not inferior to a standard radical operation (lobotomy with mediastinal lymphoadenectomy) in selective cases in which the maximum tumor diameter is 2 cm or less. The indication for a limited operation must be further examined from aspects of tumor size, tumor histology and the other factors of the tumor.
