Background:
The evolution of therapy in 105 patients with superior sulcus (Pancoast) tumor over the past 42 years was reviewed.
Methods:
There were 82 men and 23 women aged 30 to 75 years. Tumor cell types were: squamous, 41 (39%); adenocarcinoma, 23 (21.9%); anaplastic, 14 (13.3%); undetermined, 12 (11.4%); mixed, 9 (8.7%); and large cell 6 (5.7%). Therapy was based on extent of disease and lymph node involvement. There were 5 treatment groups: I, preoperative radiation and operation (n = 28); II, operation and postoperative radiation (n = 16); III, radiation (n = 37); IV, preoperative chemotherapy, radiation, and operation (n = 11); and V, operation (n = 12).
Results:
The median survival for group I was 21.6 months; group II, 6.9 months; group III, 6 months; and group V, 36.7 months. Median survival for group IV has not yet been reached (estimated at 72% at 5 years). On univariate analysis, mediastinal lymph node involvement, Horner syndrome, TNM classification, and method of therapy affected survival. On multivariate regression analysis, only N2 and N3 disease and method of therapy were significant (p < 0.05).
Conclusions:
The optimal treatment for superior sulcus tumor was preoperative radiation and operation. However, triple modality therapy, although promising, requires longer follow-up.
