Abstract: A recent report indicates that patients with squamouus cell carcinoma of the anus (SCCAC) having intraepithelial lymphocytes, have
a poor prognosis. Against that background histological sections from 277 consecutive SCCACs were reviewed searching for cases with
massive tumoral-intraepithelial lymphocytosis (TILs; ≥ 50 ITIELs /100 tumor cells). Of the 277 SCCACs, 8 (3 %) had massive TILs. These 8
patients (all females) had both more advanced clinical stage than the remaining 269 control SCCACs patients. Follow-up studies revealed that
the 8 patients with SCCACs having massive TILs had a much better 15 years survival rate than control SCCACs patients. It is concluded that
despite SCCACs patients with massive TILs had a more advanced clinical stage than SCCACs controls, SCCACs+TILs patients had a longer
survival rate (with no deaths after 5 years) than control cases. The search (v.gr. via proteomic methodology) for the lymphocyte-attracting tumor-
protein, might bring forward a novel co-adjuvant therapy, capable to increase prolonged survival time in patients having SCCACs without
massive TILs. (IJCEP709006).
Key Words: squamous carcinoma, anal canal, intratumoral lymphocytes
