Role of radiotherapy in the management of cervical carcinoma.

Different therapy schemes related with the stage of tumours are reported, after general considerations on the topic. We have evaluated various criteria for the choice of methods, pointing out the complications of therapy. Lithium-carbonate action during radiation therapy has been studied, valuing the positive effect on leukopoiesis and the consequent better clinical conditions of the patients in course of treatment. In this study we report our experience with regard to 21 patients affected by cervical neoplasia, histologically diagnosed. The stages of neoplasia in the 21 patients were so distributed: 10 at stage I B, 8 at stage II A, 3 at stage II B. Treatment consisted of three therapeutical techniques: 1) application of radium in the cervical canal and in the vaginal fornices; 2) surgical procedure; 3) application of radium against the vaginal vault. In agreement with other author's results, the histological exam of the surgical specimen confirmed in different cases the complete absence of neoplastic aspects following the pre-operative radiotherapy. Although our experience is limited, we hold that radio-surgical "sandwich" treatment of cervical carcinoma may represent an excellent therapy in young women and in patients with associated systemic diseases. The follow-up of the 21 patients has excluded up to this day any neoplasia. In this program pre-operative intracavitary radiotherapy is a primary step allowing, in the majority of the cases, the reduction of surgical radicality. In so doing, effective therapeutical results associated with a better quality of life are obtained.

Endocervical adenocarcinoma. Immunohistochemical characterization.

The presence of cytokeratins, IgA, alphafetoprotein (AFP), beta-Human Chorionic Gonadotropin (HCG), Carcinoembryonic antigen (CEA) and Epithelial Membrane Antigen (EMA) were immunohistochemically researched with a PAP method in 19 cases of endocervical adenocarcinoma. AFP and HCG were always absent, while the low and median molecular weight cytokeratins were present in 18 case (95%). These findings confirm the hypothesis of the tumoral histogenesis from the reserve cell of the endocervical epithelium. In 11 case (60%) there was a strong positivity of IgA in the lymphocytes surrounding the tumor nests, in the neoplastic cells and in the endoglandular secretion: this may represent a sign of an immune response of the patients to the tumoral antigens. CEA was present in 8 cases and EMA in 12 cases, with a unique expression: CEA positive cases showed no evidence of EMA and case with EMA positive cells were negative for the presence of CEA. Only in one case CEA and EMA were contemporaneously present. The possible interpretation of these findings is discussed.
