ABSTRACT
Tissues from 50 cases of squamous cell carcinoma of the uterine cervix were analysed for immunohistochemical expression of c-erbB-2 oncoprotein and the patients were followed-up for 2 years. Immunopositivity of c-erbB-2 was studied with reference to clinical stage, histopathological differentiation and response to the cancer therapy. Expression of c-erbB-2 protein was found to be higher (37.5%) in cases with stage II disease, whereas more expressions were noticed in poorly differentiated squamous cell carcinoma (33.3%). Among cases who showed complete response to the treatment, 20.8% were positive for c-erbB-2 oncoprotein. On the contrary, 36.8% of prognostically unfavourable cases revealed positivity for c-erbB-2 immunostaining. However, the difference between c-erbB-2 expressions of these two said groups of patients, which were divided in accordance with the response to treatment, did not attain to statistical significance. Study on c-erbB-2 among larger number of patients with cervical carcinoma may prove to be an important factor in response to cancer therapy.
