The tissues from 30 cases of endometrial cancer and 44 cases of cervical cancer were examined for oestrogen receptor activity. Twenty of the endometrial and 9 of the cervical tumours contained oestrogen receptor levels above 4 fmol/mg protein. The proportion of oestrogen receptor-positive tumours was significantly greater in adenocarcinomas of the cervix than in squamous carcinomas of the cervix. Tissues from 3 mixed mesodermal tumours of the uterus, 2 carcinomas of the vagina, a carcinoma in situ of the cervix and a carcinoma in situ of the endometrium were receptor-negative. One ovarian carcinoma and a single case of uterine sarcoma were receptor-positive. The implications of these findings in relation to hormonal therapies are discussed.

We retrospectively studied 125 patients treated for carcinoma in situ of the vulva from 1961 through 1984, with follow-up ranging from one to 24 years. Patients' ages ranged from 24 to 90 years, with a mean age of 53 years. Multifocal disease was more common in women under age 40. Pruritus was the most common complaint, but 60% of the patients were asymptomatic. Twenty-five patients (20%) had other associated malignancies: carcinoma in situ of the cervix in ten patients, invasive carcinoma of the cervix in six, multifocal carcinoma in situ involving vulva, vagina, and cervix in five, vaginal carcinoma in situ in two, and endometrial carcinoma in two. Sixty-five patients were treated primarily with wide excision, 45 with total vulvectomy, seven with "subtotal" vulvectomy, three with skinning vulvectomy, and three with vulvectomy and bilateral groin node dissection; two patients refused treatment. Fifteen patients had a recurrence--recurrent carcinoma in situ in ten, and invasive carcinoma of the vulva in five. Whether the patient had had total vulvectomy or a lesser procedure appeared to make no difference in the recurrence rate. Thus a well planned excision of vulvar carcinoma in situ appears to be the treatment of choice. All recurrences were in patients over age 40, so although the lesion is histopathologically identical in the younger patients, its biologic behavior seems to be more benign. Since it is possible, however, that invasive disease will ultimately develop in some of the younger patients, careful follow-up is still required.

In order to evaluate the etiology, incidence of malignancy, clinical risk factors and the interval between menopause and the onset of abnormal vaginal bleeding in postmenopausal women, 381 cases with a complete medical history and available histologic findings were enrolled in this study at the National Taiwan University Hospital from 1989 to 1991. The results showed that 212 (55.6%) of these women had normal histologic findings and 83 (21.9%) had benign pathologic findings, whereas 14 (3.6%) had cervical intraepithelial neoplasia (CIN), 42 (11%) had endometrial hyperplasia, 19 (5%) had cervical cancer and 11 (2.9%) had endometrial cancer. Twenty-nine (7.6%) of the cases suffered from either CIN III or cervical cancer; this number was twice as high as those with endometrial atypical hyperplasia and endometrial cancer (n = 13, 3.4%). In addition, various risk factors, especially obesity, were found to be significantly correlated with malignancy. Fractional curettage should be performed for postmenopausal bleeding patients to ensure accurate diagnosis and correct management.

The aim of this study was to define the clinical implications of semi-quantitative telomerase activity in gynecological tumors by comparing the telomerase activity of cancerous lesion and the adjacent non-cancerous lesion. In 118 cases of gynecologic tumors, including 41 uterine cervical tumors, 43 uterine body tumors and 34 ovarian tumors, telomerase activities were determined using TRAPeze telomerase detection kit for the extension reaction of the telomere sequence and the PCR reaction for amplification of the sequence, and using fluorecence-based telomere repeat amplification protocol (F-TRAP) method for the detection. In all gynecologic cancers examined, telomerase activity of the cancerous lesion was significantly higher than that of the non-cancerous lesion. Telomerase activity in the uterine cervix increased in the following order of the normal uterine cervix, cervical dysplasia and cervical cancer. Regarding the endometrial cancer, telomerase activity at the primary lesion in patients with lymph node metastases was significantly higher than that in patients without lymph node metastases. When telomerase activity was compared by histologic subtypes of the ovarian cancer, clear cell adenocarcinoma showed significantly lower telomerase activity than the other subtypes, especially endometrioid adenocarcinoma. In all gynecologic cancers examined, there was no clear correlation between the telomerase activity and age at diagnosis or age of menopause. Although all tumors with 100 units or more telomerase activity were cancerous, the sensitivity was 39% in cervical cancer, 41% in endometrial cancer and 21% in ovarian cancer, respectively. Cervical intraepithelial neoplasia (CIN) had already increased telomerase activity and endometrial cancer with lymph node metastases had also greater activity than that without lymph node metastases. Although telomerase activity in ovarian cancer tended to increase as stage advances, it is noteworthy that clear cell adenocarcinoma showed significantly lower telomerase activity than endometrioid adenocarcinoma.

A 33-year-old woman was incidentally found to have a polypoid adenofibroma on MR imaging during the evaluation of carcinoma in situ of the cervix. The position of the polypoid lesion was variable from time to time. Although the lesion was a benign pedunculated one, T2-weighted MR images showed disruption of "junctional zone" in the posterior myometrial wall of the uterus, mimicking myometrial invasion of endometrial carcinoma.

We reviewed recent cytological reporting of abnormal glandular cells on cervical smears in order to assess the predictive value of these reports and the contribution of colposcopy in the assessment of these abnormalities. The study consisted of a 5-year retrospective review of the clinical management of 80 women with abnormal glandular cells on a cervical smear, with clinical and histopathological data available for review in the interval 1992-1996. There were two groups of women: (i) those referred with gynaecological symptoms and (ii) those with screen detected abnormalities who were asymptomatic and significantly younger than the first group. The predictive value of a glandular smear for malignancy was 42.5% and for premalignancy 28.8%. The most common lesions detected were cervical intraepithelial neoplasia (CIN) (13), endometrial cancer (13), cervical adenocarcinoma (10) and cervical intraepithelial glandular neoplasia (CIGN) (8). Four cases of endometrial carcinoma presented through screening. In the remainder a variety of benign conditions were identified as responsible for the abnormal smear. Failure to find an explanation for the abnormal smear only occurred in 8.8%. In developing a protocol for abnormal glandular smears, our observations indicate that: (a) those with abnormal bleeding require endometrial sampling; (b) for those with screen detected abnormality, colposcopy is valuable as it is a sensitive predictor of early invasion and can predict glandular abnormality; (c)diseases of the entire genital tract, non-gynaecological viscera and metastatic cancer can generate cytological abnormality; (d) screen detected borderline abnormality in endocervical cells is associated with CIN III.

Coronavirus disease-2019 (COVID-19) has reduced the availability of health resources which will affect treatment of gynecological cancers. The present study aimed to provide a treatment protocol for patients with gynecological cancers during the global COVID-19 pandemic. International databases with keywords of COVID-19; Severe Acute Respiratory Syndrome; Middle East Respiratory Syndrome; gynecologic cancer; cervical cancer; and vaginal cancer, vulvar cancer, ovarian cancer, endometrial cancer, tumor, elective surgery, chemotherapy, radiotherapy, cancer, guideline, guidance, women, management, outpatient clinic visits, and triage were comprehensively searched. All the obtained guidelines were studied and the contents were summarized. During the COVID-19 pandemic, early stage endometrial cancer was preferably treated with hormone therapy while radiotherapy was given in preference in later stages. Cervical intraepithelial neoplasia 3 and high-grade squamous intraepithelial lesions should be treated immediately after diagnosis using at least a loop electrosurgical excision procedure while any major surgery should be postponed by 10-12 weeks. In the early stage of cervical cancer, surgery may be delayed by 2-4 weeks, and radiotherapy prescribed for the intervening period. In cases of an ovarian mass with negative tumor markers, no sign of cancer on imaging investigations, no ascites, a low serum CA-125 level, and no papillary projection or vegetation in the base of the cyst, the patient may be given hormone therapy for 2-3 months. In cases of newly diagnosed confirmed ovarian cancers, surgery should be performed as early as possible (maximum: 2-3 weeks). Vulvar and vaginal cancers can be treated within 10-12 weeks of diagnosis, but radiotherapy should be given in preference in this situation. A molar pregnancy is an oncological emergency for which a suction curettage is mandatory; the patient must be monitored for metastases. Information concerning the choice between open or laparoscopic surgery is limited. Given that any patient may be an asymptomatic carrier of the coronavirus, major surgery should be preceded by chest computerized tomography, with and without contrast medium, in order to detect lung lesions. Evidence concerning these recommendations is limited because of the novel and unknown nature of the COVID-19 pandemic. Furthermore, data pertaining to ethical debates about delayed treatment and treatment approaches deviating from current guidelines are also limited.
