[Electrosurgery resection of intraepithelial lesions of lower female genital tract]. / Resección electroquirúrgica de las lesiones intraepiteliales del tracto genital femenino inferior.

Twenty patients bearing lesions caused by human papillomavirus and intraepithelial neoplasia of the lower genital tract and treated with electrosurgical excision of the lesions are presented. The technique used, the benefits of the histopathologic assessment of the specimen, and the changes that this procedure produces in the specimen tissue are analyzed. In general terms, the pre and postoperative diagnosis were concordant and the early and late morbidity was found to be not significative. The efficacy of this therapy in the long term remains to be evaluated.

[Usefulness of GnRH agonists in preoperative treatment of complicated uterine myomata]. / Utilidad de los agonistas de GnRH en el tratamiento preoperatorio de la miomatosis uterina complicada.

The use of long acting gonadotropin-releasing hormone (Gn-RH) agonist produces a reversible hypogonadotropic hypogonadism. This effect has been used as presurgical treatment of uterine myomata, resulting in amenorrhea and reduction in uterus and tumour sizes. We describe the case of a 43 year old patient, having a uterine myoma associated with metrorrhagia, admitted to hospital because of extensive deep phlebothrombosis requiring urgent anticoagulation. Because of the risk of exacerbating metrorrhagia and considering the high morbidity associated to emergency hysterectomy, we decided medical treatment with a depot GnRH agonist (leuprolide acetate 3.75 mg IM monthly). Bleeding ceased within 3 days, allowing the maintenance of anticoagulant treatment. A marked reduction in uterine size postponed total hysterectomy to 3 months later. The characteristics of GnRH analogues, their action mechanisms, adverse effects and other clinical indications are discussed.

[Metastatic carcinoma to the ovary of extragenital origin: analysis of 9 cases and review of the concept of Krukenberg's tumor]. / Carcinoma metastásico en el ovario de origen extragenital: análisis de 9 casos y revisión del concepto de tumor de Krükenberg.

Between 1987 to 1992, nine patients with metastatic ovarian tumors of extragenital origin were analyzed. Seven corresponded to Krükenberg tumors, according to the traditional description of carcinoma with signet-ring cells and stroma with sarcomatoid reaction. The primary neoplasia was detected in 8 patients (89%) and corresponded to: gastric cancer (n = 4), colon cancer (n = 2), gallbladder cancer (n = 1) and breast cancer (n = 1). Mean survival in these patients was 11 months (range 4 to 20 months). Irrespective of their histology and origin, all the lesions were found to share similar macroscopic characteristics: bilateral enlarged ovaries, solid and embossed appearance.

[Genital intraepithelial lesions in immunosuppressed female patients after renal transplant: cytologic, colposcopic, and histologic study]. / Lesiones intraepiteliales genitales en pacientes inmunosuprimidas postrasplante renal: estudio citologico, colposcopico e histologico.

Twenty seven female patients immunosuppressed after renal transplantation were studied. Cytological, colposcopic and histologic studies of biopsies were used to determine the incidence of neoplastic intraepithelial lesions and those due to infection by human papilloma virus. Intraepithelial neoplasia was found in 7.4% and papilloma virus infection in 60%. Cervix cytology was insensitive (33%) for diagnosis of intraepithelial lesions. Therefore, cytology and colposcopy are recommended for routine follow up of immunosuppressed women.

[Epithelial cancer of the ovary. An analysis of a prospective protocol]. / Cáncer epitelial del ovario. Análisis de un protocolo prospectivo.

We present the results on the treatment of 43 patients with epithelial ovarian cancer excluding borderline tumours. Nine cases were FIGO Stage I, 4 FIGO Stage II, 24 FIGO Stage III and 6 FIGO Stage IV. The protocol consists in cytoreductive surgery followed by chemotherapy for Stages I, III, and IV, mainly using cisplatin + cyclophosphamide (PC) or cisplatin + adriamycin + cyclophosphamide (PAC). We used pelvis and whole abdomen radiotherapy for patients on Stage II. The follow up was between 26 and 76 months. The undifferentiated tumours had bad prognosis in Stage I, instead of receiving chemotherapy. Radiotherapy for patients on Stage II reached satisfactory local regional disease control but with late recurrences. On Stage III, size of residual tumour less than 2 cm on primary surgery was of good prognosis (60% 44 months survival). The addition of adriamycin to PC seems to be of no benefit in long term results. The five year actuarial survival was 44% for FIGO Stage I, 75% for FIGO Stage II, 16% for FIGO Stage III and 0% for FIGO Stage IV. These results don't differ significantly from similar protocols.
