Immunological abnormalities in patients with cervical carcinoma.
The cellular immune response of 58 patients affected by cervical cancer was evaluated with the aim of investigating abnormalities in T-cell populations. Subjects were divided into three groups: severe dysplasia or carcinoma in situ, microinvasive carcinoma, and invasive carcinoma. T cells were assessed by a spontaneous rosette formation test with sheep red blood cells and by reactivity with specific monoclonal antibodies of OKT series (OKT4 and OKT8 positive lymphocytes). A significant T-cell depression was observed in all patient groups; the lowest T-cell level was observed in group (b), which revealed an inverted OKT4+/OKT8+ ratio too. The results support the hypothesis that cell-mediated immunity is a key factor in premalignant status and in the early development of cervical cancer.

Intralesional recombinant alpha 2B interferon in the treatment of human papillomavirus-associated cervical intraepithelial neoplasia.
Twenty-four patients with human papillomavirus (HPV)-associated cervical intraepithelial neoplasia (CIN); of whom 13 had CIN 1, 8 had CIN 2, and 3 had CIN 3; were treated with recombinant alpha 2b interferon (IFN) by intraperilesional injections. The dosage given was 3 x 10(6) international units per day, 3 days per week for 3 weeks. In situ hybridization was carried out for HPV types 6/11 and 16/18. One year after treatment, complete response was observed in 8 (33%) cases, partial regression in 14 (58%) cases, persistence in 2 (8%) cases (in which case traditional surgical therapy was performed), and progression in none of the cases. Adverse effects (asthenia, fever, chills, and headache) were observed in 20 (83%) cases. None of the patients had myelodepression. Intraperilesional treatment of HPV-associated CIN with recombinant alpha 2B IFN does not appear to be a valid substitute for traditional treatment, but it could be considered in certain cases when surgery is not advised.
