N2 - Background. Squamous cell lung carcinoma (SLC), the most frequent type of lung cancer, generally is treated surgically and its prognosis is poor. The only current clinically useful prognostic criterion is lymph node staging (TNM classification). Expression of a novel tumor‐associated carbohydrate epitope Galβ1–3[Fucαl‐4]GlcNAcβ1‐4[Fucα1–3]GlcNAcβ1–3Galßl‐4Glc identified by the 43‐9F monoclonal antibody (MoAb) is associated with the growth pattern of SLC cell lines in athymic mice and in vitro. This implies that the 43‐9F epitope may be related to tumor progression in patients with SLC and that, as such, it could be of prognostic value. Methods. Primary tumor specimens from 231 patients with lung carcinoma (130 with SLC, 64 with adenocarcinoma, 10 with small cell carcinoma, 16 with large cell carcinoma, and 11 with adenosquamous carcinoma) were examined by immunohistochemical studies on formalin‐fixed, paraffin‐embedded tissue samples for immunoreactivity with an MoAb to the 43‐9F antigen. Univariate and step‐wise Cox regression analyses were used to compare survival time by histopathologic diagnosis, smoker status, TNM classification, and type of surgical treatment. Results and Conclusions. Patients with 43–91: epitope‐positive SLC tumors had a significantly (P < 0.01) better prognosis than patients with epitope‐negative tumors. In contrast, no association was seen between 43‐9F epitope expression and survival time for patients with lung adenocarcinomas. Further, the prognostic value of 43‐9F expression in SLC was found to be superior to the N‐classification with the added advantage that it requires access only to primary tumor tissue and thus is available before therapy.
