[Repeat surgery of intrapulmonary metastases]

The results of repeat surgery for pulmonary metastases in 17 cases are discussed. The study was based on the data of 38 repeated interventions for metastases following lung resection for cancer, bilateral metastases and recurrent pulmonary metastases. All surgery was carried out as a component of combined treatment including chemotherapy and radiation. It was intended to increase the effect of chemotherapy by cutting down the size of tumor. Surgery was not performed unless lesions were limited in number (solitary metastases) and when there were local recurrences of primary tumor or distant metastases to other organs. The extent of resection should be as limited as possible to preserve lung tissue. It is increased of necessity in cases of repeat removal of metastases from the same lung; lobectomy or pulmonectomy is indicated in such cases. Both short- and long-term results show good tolerance of surgery by patients, low incidence of complications and longer survival when patients are supported by chemo- or chemoradiation treatment.
