ABSTRACT
BACKGROUND: Aim of this study was to investigate the prognostic significance of CD3+ TILs in infiltrating ductal carcinoma (IDC) of the breast. MATERIALS AND METHODS: Immuno-histochemistry was done with CD3 antibodies in tissue sections of 127 breast cancer patients, and CD3+ intra-tumoral and stromal TILs were counted in relation to clinico-pathological variables. RESULTS: Intra-tumoral and stromal CD3+ TILs were significantly associated with positive lymph node status (P = 0.006, P = 0.043, respectively) without significant association with age, menopausal status, family history, and hormonal status. The higher CD3 intra-tumoral and stromal counts both showed significant association with good prognosis (P = 0.039, P = 0.044, respectively). The intra-tumoral count was higher than stromal count and was independently associated with disease-free survival in stage I and II cancer (P = 0.021). CONCLUSIONS: CD3+ TILs may serve as independent marker of good prognosis in IDC breast. The findings of this study need further validation on a larger sample size.

Chronic occlusive arterial diseases form a single largest entity amongst the peripheral vascular diseases. Current operative methods available for improving circulation often elicit poor results and the patient has to undergo an amputation. The technique of pedicled omental transfer has given hope of saving such unsalvageable limbs. Although symptomatic and clinical improvement has been reported by this method of "biological by-pass revascularisation", there are no simple, objective and easily reproducible tests to assess improvement in circulation. In this study pulse oximetry and stress testing have been used to assess revascularisation. This study comprised 56 patients (78 limbs) suffering from chronic occlusive arterial disease, spanning a period of 5 years. Patients were investigated and subjected to pedicled omental transplantation (omentopexy). Symptomatological assessment showed improvement in intermittent claudication in about 85% of patients, relief from rest pain in 86% and healing of chronic ulcers in 73% of patients. Objective tests of stress testing and pulse oximetry also showed improvement in circulation. Relief from ischaemia was more in cases of Buerger's disease (TAO) than in cases of atherosclerosis obliterans (ASO).
