Diabetic women may have an increased risk of developing endometrial carcinoma. Ovarian and adrenal activity seem to be factors in the genesis of this cancer. We have measured serum sex hormone-binding globulin (SHBG), free and bound fractions of estrogens and androgens, and gonadotropins in 20 consecutive postmenopausal insulin-treated diabetic women and 16 normal postmenopausal women. The diabetics were nonketoacidotic, without nephropathy and without proliferative retinopathy. The groups were comparable regarding age and percent ideal body weight. The diabetic group had significantly increased serum levels of estrone (P less than 0.001), estrone sulfate (P less than 0.05), 17 beta-estradiol (P less than 0.02), and SHBG (P less than 0.001). Levels of testosterone, delta 4-androstenedione, and dehydroepiandrosterone sulfate tended to be higher (not significantly) in the diabetics. FSH and LH levels were similar in the two groups, while serum PRL was significantly lower in the diabetic group (P less than 0.02). The hormonal changes in the diabetics were not related to control of the diabetes. We conclude that total estrogen levels are increased in postmenopausal women with insulin-treated diabetes mellitus. High SHBG levels in these patients tend to keep the free fractions of sex hormones within normal limits.

Two sisters with Laurence-Bardet-Biedl-Moon syndrome were observed. This consists of mental retardation, pigmented retinopathy, polydactyly, obesity and hypogenitalism. Both had carcinoma of the endometrium shortly after age 40. The question is raised whether factors in this syndrome predispose to carcinoma of the endometrium.

We present the fourth known case of endometrial carcinoma, and the second case of endometrial small-cell carcinoma, to be associated with paraneoplastic retinopathy. Initial symptoms were decreased visual acuity and a narrowing of the visual field. Endometrial carcinoma was diagnosed several months later. An antibody to 34-kDa bovine retinal antigen was detected in the patient's serum. Thus, autoimmunity was suspected as the cause of the retinopathy. In patients with endometrial carcinoma with visual disturbance of unknown cause, paraneoplastic retinopathy should be suspected.

Cancer-associated retinopathy (CAR) is a rare paraneoplastic syndrome. In this survey we report about two further patients with CAR, who were referred to the University Eye Hospital of Tuebingen within a few months. The most common primary tumor associated with CAR is small cell carcinoma of the lung. Case reports about rhabdomyosarcoma, carcinoma of the endometrium, prostate and mamma were also described. The exact pathogenesis of CAR is still unknown. Specific autoantibodies were found against the photoreceptor protein recovering (23-kd retinal CAR antigen). However, this reaction is not present in all patients, and probably other antigens are also involved. Most of the patients experience symptoms of CAR before the primary tumor is detected. Besides glare sensitivity and flashing lights, a rapidly progressive, often asymmetric visual loss may occur. Although paracentral and mid-peripheral scotomas can be found frequently, visual field defects are often quite heterogeneous. Typically, the responses in the electroretinogram (ERG) are markedly reduced, but normal ERGs were also described. The fundus picture in CAR shows sheathing of the retinal vessels, narrowing of the arterioles and clumbing of the retinal pigment epithelium. The prognosis is poor. Frequently there is progression to bilateral loss of vision within a few months. Treatment of the primary tumor does not seem to alter the ocular prognosis. Systemic corticosteroids may be helpful in some patients. Nevertheless, no proven therapeutic regimen is currently available.

Cancer-associated retinopathy (CAR) is an ocular manifestation of a paraneoplastic syndrome whereby immunological reactions to retinal antigens aberrantly expressed in tumor cells lead to the degeneration of retinal photoreceptor cells. In our previous study (H. Ohguro et al., Invest. Ophthalmol. Vis. Sci., 40: 82-89, 1999), recoverin, a retina-specific calcium-binding protein, and heat shock cognate protein 70 (hsc 70) were identified as autoantigens recognized by sera from patients with CAR. Therefore, we suggested that autoimmune reactions against both recoverin and hsc 70 might be involved in the pathogenesis of CAR. To elucidate the initial step of the molecular pathology of CAR, we examined the expression of recoverin and hsc 70 by reverse transcription-PCR and Western blot using cell lines of several kinds of cancers, including lung small cell carcinoma, lung adenocarcinoma, gastric cancer, pancreatic cancer, breast cancer, uterine cervical cancer, endometrial cancer, and leukemia. Recoverin was expressed in 21 of the 31 cancer cell lines. The expression levels of hsc 70 were significantly higher in cancer cell lines than in noncancerous cell lines. However, no difference in the expression levels of hsc 70 was observed between recoverin-positive and -negative cell lines. Immunofluorescence labeling by the affinity-purified recoverin antibody revealed the immunoreactivity to recoverin as a granular pattern within the cancer cells. Lung adenocarcinoma A549 cells, which did not express recoverin, exhibited a significant reduction in cell proliferation upon transfection with human recoverin cDNA. Taken together, our present data suggest that the retina-specific calcium-binding protein recoverin is expressed in more than 50% of a variety of cancer cells and may play a significant role in the cell proliferation of these tumor cells.

We reviewed the literature for cases in which gynecologic malignancies caused paraneoplastic retinopathy and ultimately led to blindness. Twenty-eight cases were derived from the literature, and one unique case is described from our institution. Of these 28 cases, 14 patients were diagnosed with endometrial cancer, 7 with ovarian cancer, 5 with cervical cancer, 1 fallopian tube cancer and 1 with concomitant endometrial and ovarian cancers. The average age of patients at the time of diagnosis was 64 years (range, 35-89 years). Typically, ocular manifestations antedate symptoms of the underlying carcinoma by 3-12 months. Information regarding the interval from visual symptoms to time of death is limited, but ranges from several months to several years. Our report is the first to document a clear cell carcinoma of the endometrium causing paraneoplastic retinopathy and is the first to review all gynecologic malignancies associated with visual paraneoplastic syndromes.
