[Recurrence of lung cancer--its treatment and prevention]

A recurrence fashion of lung cancer mainly depends on the histology type of the cancer. Usually, in squamous cell carcinoma, local recurrence is observed, but in adeno- and small cell carcinoma, hematogenous distant metastasis is more frequent. To treat these recurrent lesions in the lung, suitable therapeutic manner must be selected, considering pulmonary function. In this paper, we demonstrated the recent advances of a combined adjuvant therapy for lung cancer, surgical treatment for metastatic lung cancer, and photoradiation therapy with LASER and X-ray to improve the ventilatory capacity in cancer patients. It was also demonstrated the significant prolongation of the tumor free interval and decrease of recurrence rate of cancer patients with long term intermittent adjuvant immuno-chemotherapy by use of transfer factor.
