Establishment of laboratory models of gynecologic neoplasms provides an important means of studying the biologic characteristics of these tumors. We report a previously uncharacterized human endometrial adenocarcinoma cell line that produces both intraperitoneal and subcutaneous growth in nude mice. The line was derived from a poorly differentiated endometrial cancer and has been carried in continuous tissue culture for greater than 100 passages. Doubling time in culture is approximately 48 hr. Antigenic phenotyping against a panel of murine monoclonal antibodies by rosetting cell surface assay on live cells or peroxidase assay on fixed cells has shown reactivity with a number of determinants, including MH99, MT334, MQ49, and the blood group antigens F3, 118, and 41-83. Cytogenetically, the line displays an aneuploid human karyotype with several chromosomal rearrangements and deletions. When injected intraperitoneally into nude mice, animals develop intraperitoneal nodules and ascites and succumb with wasting in 30-40 days. The intraperitoneal tumor has been passaged multiple times in nude mice by direct transfer of ascites. Subcutaneous injection of tumor cells produces nodules that grow at a reproducible rate. By light and electron microscopy, the nude mouse tumor is a poorly differentiated adenocarcinoma, similar to the original patient's tumor. It expresses both estrogen and progesterone receptors. CA 125 is not elevated in the serum of animals with tumor implants. The line appears to be cisplatin sensitive as determined by rates of growth of subcutaneous nodules. This cell line may be useful in studying the in vitro and in vivo properties of human endometrial carcinoma.

Having seen 192 cases of cancer of the endometrium treated at the Institute Paoli-Calmettes between the years 1975 and 1980, the authors have been able to evaluate the place of surgery in the planning of treatment of Stage I and II cases. They hold that: Laparatomy is well tolerated, in 90% of cases of Stage I, 88% of cases of Stage II, 70% of older than 70 years of age and 79% of patients who have some wasting there was no operative mortality. The need to re-explore Stage I and Stage II cases surgically (14%) especially when invasion of the ovaries had not been recognized before histological examination exists. The bad influence of the 5 year survival rate of histological grade 3 or where the myometrium was deeply invaded or where the pelvic lymph nodes were invaded. Studying this personal series and other series found is the literature shows that there is no great value in clearing the pelvis of lymph nodes in order to plan the post-surgical treatment. This is because generally lymph node involvement in the pelvis is associated with other factors that are unfavourable prognostically and these factors can be determined more easily than by removing the lymph nodes. They are, grade 3, invasion of the cervix, positive peritoneal cytology and when the myometrium has been invaded more than 50%. It was only in two cases out of 122 that study of the lymph nodes of the pelvis altered the treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Megestrol acetate is a progestational agent for treatment of metastatic breast cancer and endometrial cancer. Megestrol has also been used as an appetite stimulant for patients with human immunodeficiency virus and malignancy who experience cachexia and wasting; also, megestrol can be beneficial in relieving hot flashes in women and men. Megestrol has been shown to have a glucocorticoidlike effect and has been associated with substantial suppression of plasma estradiol levels. We describe 2 patients who recently presented to our Metabolic Bone Disease Clinic with severe osteoporosis complicated by multiple vertebral fractures experienced while the patients were receiving high-dose megestrol therapy. The patients had evidence of adrenal axis suppression but recovered fully after megestrol was discontinued. We speculate that megestrol was an important factor in the development of osteoporosis and subsequent fractures. Further study is warranted to clarify the relationship between megestrol and its potential for adversely affecting the skeleton.
