From January 1988 to August 1992, 18 patients (pts) with the established diagnosis of non-small cell lung cancer of the superior sulcus have been treated with a multidisciplinary approach, which includes 1-3 cycles of neoadjuvant chemotherapy (MVP or MCP regimens) followed by simultaneous preoperative chemotherapy and external beam irradiation. Radical surgery plus intraoperative radiotherapy (IORT) was planned 4-5 weeks after the end of the preoperative protocol.
Tumor stages were IIIA (9 pts) and IIIB (9 pts). Tumor characteristics included rib and vertebral involvement in 15 and 4 pts, respectively. Fatal toxicity was present in 3 pts (16.6%). Resectability rate was 76.4%. Pathologic findings disclosed complete response (pT0) in 70.5% of the surgical specimens and viable tumor (pT+) in 29.5%. With a median follow-up of 24+ months (2-52+), 4-year actuarial local control, and overall survival rates are 91% and 56.2%, respectively. Four-year actuarial overall survival according to pathologic response was 87.5% for pT0 patients and 20% for pT+ patients.
We conclude that this regimen promotes a high rate of pT0 as well as better than expected local control and survival rates. The presence of a pT0 specimen seems to correlate with the patient outcome.
