In this country, hormone replacement therapy (HRT) has been used more extensively in the last few years. The benefits of HRT in cardiovascular diseases, osteoporosis and quality of life has been well established. Breast cancer and endometrial carcinoma have been considered as contraindications for HRT. A reappraisal of this practice is necessary since we have no evidence that HRT may adversely influence the outcome of these tumours. Nevertheless, theoretically this is possible because the effect of estrogens on occult metastases in unknown. The relationship between replacement therapy and the uterine sarcomas is of particular concern. HRT is safe in patients successfully treated for carcinoma of the vulva, vagina, uterine cervix and in those with ovarian cancer. Experience suggests that the estrogen can also be used safely in women treated previously for endometrial cancer. As far as breast cancer is concerned it appears logical to discuss the risk-benefit considerations with our patients before embarking on using HRT. Consultation with a gynaecological oncologist prior to HRT in patients with endometrial and/or breast cancer is strongly recommended.

Autologous blood transfusion, as an alternative to homologous blood, must be considered for those patients who require blood. Transfusion in gynecologic oncology surgery is often required and autologous blood transfusion has been utilized. Between January 1988 and December 1992 a total of 162 surgical procedures for gynecologic cancers were performed in the same number of patients. Of these only 102 were eligible for autologous blood transfusion as predonation. The mean age of patients was 57.8 years (range 35-81). Forty-three patients were affected with endometrial carcinoma, 31 with carcinoma of the cervix, 21 with ovarian carcinoma and 7 with vulvar cancer. Collected autologous blood units were 138 (mean 1.35 every patient). Indications for predeposited blood transfusion was given by a hemorrhage greater than 100 cc intraoperatively or hemoglobin level less than 10 g/dl until 1988 or less than 8 g/dl since 1989. Forty-eight (34.8%) of the collected units were transfused to 39 autologous donors (mean 1.2 units every patient). There was a significant difference in transfusion rate in patients: endometrium 25.8%, ovary 28%, cervix 45%, vulva 72.7%. Unused autologous blood units were discarded at the expiration date: they were 90, 65% of collected ones. In 6 patients homologous blood was necessary other than autotransfusions. Our experience demonstrates that the transfusion requirement in gynecologic cancer surgery depends on pattern of neoplasm and consequently of surgical procedure. Patients with carcinoma of the cervix and vulva are at risk for transfusion and have appropriate indications for autologous donation.(ABSTRACT TRUNCATED AT 250 WORDS)

The prognostic impact of FIGO stage, histology, histologic grade, age and race in survival for cancers of the female gynecological (cervix, endometrium, ovary, vulva, vagina) were examined using cases obtained from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program that were diagnosed between 1973 and 1987. Utilizing Cox proportional hazards modeling and relative survival rates analysis of 17,119 cases of cervical cancer indicated that the International Federation of Gynecology and Obstetrics (FIGO) stage, histology, histological grade, lymph node status, and age at diagnosis were all independently prognostic. No evidence was found of survival differences between squamous cell carcinoma and adenocarcinoma. Younger women were not found to have a poorer prognosis, survival declined with increased age. Analysis of 41,120 cases of endometrial cancer indicated that FIGO stage, histology, histologic grade, lymph node status, age at diagnostic, and race were all prognostic factors. Clear cell adenocarcinoma, leiomyosarcoma, and mixed mullerian tumors were all found to have poorer prognosis. Analysis of 21,240 cases of ovarian cancer indicated that FIGO stage, histology, histologic grade, lymph node status, age at diagnosis, presence of ascites, and race were all prognostically significant. Analysis of 2,575 cases of vulvar cancer indicated that FIGO stage, histology, histologic grade, age, and race were all prognostically significant. Analysis of 916 cases of vaginal cancer indicated that FIGO stage, histologic grade, lymph node status, and age are all prognostically significant. Additional analysis of the data by combinations of independent prognostic factors indicates that the interaction of factors may be more predictive of outcome than any one factor separately.

The surgical management of malignant gynecologic disease continues to evolve as more is learned about the natural history and biology of these neoplasms. Whereas curing malignancies remains the ultimate goal of most surgical procedures for gynecologic cancers, the importance of quality of life cannot be ignored. Surgical procedures that enhance the quality of life without compromising cure continue to be explored. In vulvar cancer, the disfiguring classical radical vulvectomy is being replaced by more conservative procedures. As anesthetic techniques and postoperative care continue to improve, the role of radical surgery for invasive and recurrent cervical cancer has been extended to include older women. Ovarian cancer continues to be the most lethal of all gynecologic malignancies, and the role of aggressive primary and secondary cytoreduction continues to be defined. The new International Federation of Gynecology and Obstetrics staging system for endometrial cancer has generated controversy regarding the benefits and morbidity associated with surgical staging.

The use of combined modality therapy in the primary management of gynecologic cancer continues to be explored. Although early ovarian cancer is treated with postoperative adjuvant treatment, the data to support its value is lacking. In advanced disease, paclitaxel has emerged as the most optimal treatment after maximal cytoreduction. Although studies on consolidative therapy using radiotherapy, intraperitoneal therapy, or further chemotherapy are reported, there are no comparative data against a control arm. In those subsets of endometrial cancer patients who have a poor survival, adjuvant treatment strategies using chemotherapy or wide-field whole-abdominal therapy is being evaluated to improve outcome. Small phase II studies of either sequential or concurrent chemotherapy with radiation continue to be reported in advanced cervix cancer, yet large prospective randomized trials comparing standard radiotherapy to combined chemotherapy and radiotherapy are scarce. Alternative strategies to standard surgery to limit morbidity is being explored in the management of vulvar cancer with encouraging results. More properly conducted phase III trials are necessary to evaluate the efficacy of these newer treatment strategies.

We reviewed the published medical literature to assess the impact of the use of estrogens, with and without progestogens, on the incidence of gynecologic cancer in postmenopausal women. Long-term use of an estrogen preparation that is not accompanied by a progestogen is associated with a large increase in the risk of endometrial cancer, an association that almost certainly is a causal one. The incidence of endometrial cancer in women who receive combined estrogen-progestogen therapy is not elevated to nearly the same degree. There are suggestions that, depending on the particular combined regimen, the incidence need not be elevated at all beyond that of a women who has never taken hormones. The occurrence of other forms of gynecologic cancer appear not to be associated with the use of unopposed estrogens, though relevant data on cervical cancer are sparse. The relation of ovarian, cervical and vulvar cancer to the prior use of combined estrogen-progestogen therapy has only begun to be evaluated.

Urinary gonadotropin peptide (UGP) is a 10,300 Dalton peptide which is present in the urine of pregnant women, those with trophoblast disease and those with, certain nontrophoblastic malignancies. We examined the efficiency of UGP measurement at differentiating benign from malignant gynecologic and breast diseases. UGP was measured in 1355 spot urine samples from 841 patients (343 samples from 323 healthy women and women with benign gynecologic and breast diseases, 1012 samples from 518 women with gynecologic malignant diseases or breast cancer). Using a cutoff of > 3 fmol UGP/mg urinary creatinine the specificity was 97%. The sensitivity of UGP was calculated from pretherapeutically collected samples (n = 210). The sensitivity of the test for all malignancies was 26% (ovarian malignancy (n = 27) 52%, endometrial cancer (n = 25) 32%, cervical cancer (n = 49) 29%, breast cancer (n = 72) 19%, vulvar cancer and vaginal cancer (n = 12) 17% and for carcinoma in situ of the breast or the cervix (n = 20) 0%). We also found significantly higher UGP values in postmenopausal women than in premenopausal women. Hormonal substitution significantly lowered the UGP values.

In the treatment of locally advanced carcinoma of the uterine cervix the multimodal therapeutic approach is useful to improve overall survival and disease-free survival. Two studies of concomitant radiochemotherapy were conducted. In the first, recurrences of gynecologic tumors were treated, in the second primary tumors of the uterine cervix. In the first study 29 patients, of whom 15 with endometrial cancer recurrence, 10 with cervical cancer recurrence and 4 with vulvar cancer recurrence were treated with FUMIR schedule (5-FU and mitomycin C plus concomitant radiotherapy to the pelvis in two cycles of 23.4 Gy) and subsequent brachytherapy boost. In the second study 17 patients, of whom 14 evaluable, were treated with external beam radiotherapy (ERT 40 Gy) and concomitant chemotherapy (5-FU and CDDP). Before and after treatment the patients were examined with MRI. After radiochemotherapy radical hysterectomy and histology of surgical specimen was performed. Results of first study were as follows: acute G1-G2 (RTOG) hematologic toxicity 56%, G3 4%; G1-G2 gastrointestinal 54%, G1-G2 skin 29%; G1-G2 rectum 24%; G1-G2 bladder 25%; G1-G2 vagina 30%. Local control, overall survival and disease-free survival at 24 months were 45%, 76% and 67%, respectively. Results of the second study showed 9/14 patients with complete response and 4/4 patients with partial response (93%), no change in 1, with 100% MRI accuracy as compared to histology. Based on these results a phase III clinical trial was planned in primary cancer of the uterine cervix using concomitant radiochemotherapy (CDDP + 5-FU) plus intracavitary brachytherapy for organ preservation.

The purpose of this study was to evaluate retrospectively the surgical infectious morbidity in gynecologic cancer. We examined 1,180 gynecologic oncology patients: 608 women had carcinoma of the endometrium, 510 cancer of the cervix, 48 ovarian cancer and 14 vulvar cancer. Thirty-five (6%), 92 (18%), 7 (15%) and 2 (14%) were complicated by infection in carcinoma of the endometrium, cancer of the cervix, ovarian cancer and vulvar cancer, respectively. Our conclusion is that the highest surgical infectious morbidity occurs in patients with cervical cancer and the lowest in patients with carcinoma of the endometrium.

Telomerase is a ribonucleoprotein that synthesizes telomeric DNA onto chromosomal ends using an RNA component as a template. Extension of telomeric repeats by telomerase prevents telomere shortening with cell divisions and contributes to chromosomal stability, possibly leading to immortalization of the cells. In the present study, we determined the telomerase activity of gynecological tumors and cell lines using a newly developed non-radioisotope telomeric repeat amplification protocol. A total of 21 cell lines derived from cervical cancer, endometrial cancer, ovarian cancer, and choriocarcinoma was examined, and all lines were found to be positive for telomerase activity, although the activity varied among cell types. A total of 50 gynecological malignant tumors was also examined, and 10 of 12 (83%) cervical cancers, 12 of 13 (92%) endometrial cancers, 18 of 21 (86%) ovarian cancers, 2 of 2 tubal cancers, and 1 of 1 vulvar cancer were found to be positive for telomerase activity. A total of 88% of gynecological tumors tested was thus found to be telomerase positive. However, no significant correlation was observed between telomerase activity and clinical features for any tumor type, although ovarian tumors expressing high telomerase activity tended to be more invasive. In contrast to that in malignant tumors, telomerase expression was weak and less common in premalignant lesions, with 5 of 7 cervical intraepithelial lesions and 4 of 6 borderline ovarian tumors exhibiting faint activity. Nine benign uterine lesions were also examined, and all were negative for telomerase activity except 1 uterine myoma, which had a weak signal. Three benign ovarian cysts examined had weak telomerase activity. These findings suggest that telomerase activation is common in gynecological malignant tumors and may be a critical step in their pathogenesis. However, premalignant lesions and some types of benign tumors also express weak telomerase activity.
