Based on clinical as well as experimental studies, limited operation of choice was evaluated for the management of lung cancer. From clinical analysis of 39 cases who underwent limited lung resection, our clinical experiences indicated that this operative procedure would be feasible for a large tumors of approximately 4cm in diameter. However, the incidence of lymphnode metastasis is more likely to be high when applied to the tumors of more than 3cm in diameter. The favorable indication, therefore, is for the cancer less than 3cm in diameter. By careful evalution of 7 cases with postoperative recurrence, it has become obvious that either the degree of cell differentiation or the existence of lymph nodes metastasis strongly participate in its prognosis. According to hemodynamic studies immediately after surgery, limited resection of the lung is preferred to conventional radical lobectomy for patients with cardiovascular malfunction because it serves to eliminate a possible left ventricular failure after surgery. An experimental research also demonstrated favorably hemodynamic benifits of limited resection for reducing left ventricular overloading on coronary diseased heart which is experimentally prepared by either creation of stenosis of the main left coronary artery or ligation of the left descending coronary artery. The immune response in the lymphnodes to a tumor growth also was attested in C3H mice with use of MH 134 tumor inoculated, especially in relation to the time of tumor resection. The results of our experiments confirmed that tumor resection on the 7th and 10th
