Preoperative chemotherapy in epidermoid bronchogenic carcinoma

Palliative chemotherapy in cases of epidermoid bronchogenic carcinoma, initially judged to be inoperable, made it possible to perform operative resection in 50 cases. An association of cis-platinum and bleomycin was used, this combination having previously been considered synergistic. In certain cases the tumour seemed to have disappeared on macroscopic examination of the resected specimen, and in some instances no tumoral cells could be found on histological examination. This series brought out several positive features: chemotherapy made it possible to operate on patients previously judged to be inoperable; it ensured maximum local efficiency of drugs because of the absence of abnormal vascularity; and it made it possible to anticipate the cure of occult metastases. However, three negative aspects were also present: modification of postoperative TNM classification making it difficult to establish a prognosis; difficulty in determining therapeutic strategy for pNo; and inadequate long-term follow-up. On the whole the positive points appeared to outweigh the negative aspects, but a randomized study is necessary to confirm this.
