[Assessment of surgery for primary lung cancer with dissemination or malignant effusion of pleura (T4 advanced lung cancer)].
Twenty-four cases of primary lung cancer with dissemination or malignant effusion of pleura detected preoperatively or intraoperatively were surgically treated at our hospital. Mean survival time (MST) and two-year survival rate (2 YSR) were analyzed on their resected cases and non-resected cases with similar lesion. MST and 2 YSR of 19 cases with lobectomy, 5 cases with pneumonectomy including pleuropneumonectomy and 15 cases with no surgical procedure were 2.77 +/- 0.60 years, 53.4%, 1.51 +/- 0.50 years, 26.7% and 0.99 +/- 0.15 years, 6.7%. MST and 2 YSR of 13 cases with lymph node dissection under R 1 and 6 cases over R 2 on lobectomy group were 1.99 +/- 0.38 years, 37.5% and 5.66 +/- 1.71 years, 66.7%. These findings suggested that lobectomy with lymph node dissection of R 2 over may be a beneficial treatment of lung cancer with dissemination or malignant effusion of pleura.
