Methodologic concerns in defining lesbian for health research.

A recent report from the Institute of Medicine recommends more methodologic and substantive research on the health of lesbians. This study addresses one methodologic topic identified in the Institute of Medicine report and by a subsequent scientific workshop on lesbian health: the definition and assessment of sexual orientation among women. Data are from the Women Physicians' Health Study, a questionnaire-based U.S. probability sample survey (N = 4,501). The two items on sexual orientation (current self-identity and current sexual behavior) had a high response rate (96%), and cross-tabulation of responses indicated several combinations of identity and behavior. Three conceptually different definitions of "lesbian" are compared on the basis of (1) identity only, (2) sexual behavior only, and (3) both identity and sexual behavior. Suggestions and cautions are given to researchers who will add items on sexual orientation to new or ongoing research on women's health.

Krukenberg tumors: can management be improved?

OBJECTIVE: The Montefiore Medical Center experience with women with gastrointestinal (GI) cancer was reviewed to: (1) evaluate clinical parameters in patients with Krukenberg tumor (GI cancer metastatic to the ovaries) and (2) evaluate oophorectomy in GI cancer patients. METHODS: (1) Charts of all female patients admitted between 1985 and 1996 with gastric or colon cancer were reviewed. RESULTS: The frequency of Krukenberg tumor was 7/1,021 (0.7%). The median age at presentation was 39.5 years (range 35-80); 5 were premenopausal, 2 of whom were postpartum. Krukenberg tumor was significantly more common in the premenopausal patients with gastric cancer (p = 0.002), colon cancer (p = 0.001), and in both sites combined (p < 0.001). Our rate of pregnancy-associated Krukenberg tumors (28.6%) was significantly higher (p < 0.05) than that found in 4 of 5 large studies. The average survival of our 7 patients was 12.3 months (range 4 days to 26 months), with secondary debulking and chemotherapy offering 1 patient the longest longevity. Only 19/788 (2.4%) women had oophorectomy during their colon cancer surgery revealing 2 (10.5%) Krukenberg tumors, 6 (31.6%) benign solid or cystic ovarian tumors, and 11 (57.9%) normal or atrophic ovaries. CONCLUSIONS: Krukenberg tumors are rare. There is no uniformity of data reported in the literature. Krukenberg tumors were more common in premenopausal women with gastric or colon cancer compared to postmenopausal women. Our rate of pregnancy-associated Krukenberg tumors appeared to be higher compared to other studies. Prophylactic oophorectomy in pre- and postmenopausal women should be considered at the time of GI cancer surgery, and requires further study. A national registry combined with prospective, multisite studies are needed to gather data and evaluate treatment.

Nongestational choriocarcinoma in the postpartum period: a case report.

PURPOSE: To determine the tissue of origin (gestational versus nongestational) of an extensive metastatic choriocarcinoma in an 18-year-old woman to determine prognosis and treatment. METHODS: DNA microsatellite polymorphisms after polymerase chain reaction (PCR) amplification of the tumor tissue and blood from the patient, husband, and daughter were used to determine the tissue of origin. RESULTS: Molecular analyses revealed that the tumor shared the genetic features of only the patient. She responded well to multiagent chemotherapy. CONCLUSIONS: Molecular analysis is a useful tool to determine whether a choriocarcinoma occurring in a female patient of child-bearing age is gestational or nongestational when clinical findings are not clearly indicative of the primary.

Transvaginal ultrasonography compared with endometrial biopsy for the detection of endometrial disease. Postmenopausal Estrogen/Progestin Interventions Trial.

BACKGROUND: Transvaginal ultrasonography is a noninvasive procedure that may be used to detect endometrial disease. However, its usefulness in screening for asymptomatic disease in postmenopausal women before or during treatment with estrogen or estrogen-progesterone replacement is not known. METHODS: We compared the sensitivity and specificity of transvaginal ultrasonography and endometrial biopsy for the detection of endometrial disease in 448 postmenopausal women who received estrogen alone, cyclic or continuous estrogen-progesterone, or placebo for three years. RESULTS: Concurrent ultrasonographic and biopsy results were available for 577 examinations in the 448 women, 99 percent of whom were undergoing routine annual follow-up. Endometrial thickness was less than 5 mm in 45 percent of the examinations, 5 to 10 mm in 41 percent, more than 10 mm in 12 percent, and not measured in 2 percent, and it was higher in the women receiving estrogen alone than in the other groups. Biopsy detected 11 cases of serious disease: 1 case of adenocarcinoma, 2 cases of atypical simple hyperplasia, and 8 cases of complex hyperplasia. Biopsy also detected simple hyperplasia in 20 cases. At a threshold value of 5 mm for endometrial thickness, transvaginal ultrasonography had a positive predictive value of 9 percent for detecting any abnormality, with 90 percent sensitivity, 48 percent specificity, and a negative predictive value of 99 percent. With this threshold, a biopsy would be indicated in more than half the women, only 4 percent of whom had serious disease. CONCLUSIONS: Transvaginal ultrasonography has a poor positive predictive value but a high negative predictive value for detecting serious endometrial disease in asymptomatic postmenopausal women.

Human papillomavirus-associated cervical intraepithelial neoplasia following lesbian sex.

BACKGROUND: Less than 3% of lesbians develop cervical dysplasia, with increasing risk correlating with previous heterosexual activity. Because they are not currently sexually active with men, many lesbians do not perceive themselves to be at risk for developing dysplasia and do not obtain regular Papanicolaou smears. There are no standard recommendations for Papanicolaou smear intervals for lesbians. CASE: A 36-year-old, nonsmoking woman had a Papanicolaou smear history of a high-grade squamous intraepithelial lesion of the cervix, which was confirmed by biopsy and successfully treated by laser ablation. Human papillomavirus type 16 was identified in the cervical biopsy by polymerase chain reaction amplification and restriction fragment polymorphism analysis. The patient gave a clear history of having had sexual activity only with women. CONCLUSION: Regular Papanicolaou testing should be recommended to all lesbians, regardless of type of sexual activity. Papanicolaou testing intervals should be determined using standards similar to those used for heterosexual women: annually after onset of sexual activity or after age 18, and possibly less often after three normal smears at her physician's discretion. An extensive number of sexual partners, current smoking, and prior dysplasia may influence the physician to advise continued yearly Papanicolaou testing for lesbians, similar to advice given to heterosexual patients.

Ovarian carcinoma metastases to gastrointestinal tract appear to spread like colon carcinoma: implications for surgical resection.

OBJECTIVE: To profile the incidence of mesenteric lymph node metastases in patients with ovarian carcinoma and metastases to the gastrointestinal tract in order to determine the optimal technique for surgical debulking. METHODS: The slides and charts of all patients with ovarian carcinoma who had undergone bowel resection were retrospectively reviewed and follow-up information was obtained. RESULTS: Of 100 separate bowel resections 44% had penetration of metastases to the muscularis, 18% had invasion through the submucosa, 4% had mucosal perforation, and two patients had clinical perforation. Fifty-five percent of all resections demonstrated lymph-vascular space invasion (LVSI). In the 33 specimens which included pathologic analysis of mesenteric lymph nodes, 79% had positive LVSI, which correlated with the presence of mesenteric lymph node metastases (P = 0.05) but not histologic grade (P = 0.20). When surgery was performed for secondary debulking, the frequency of mesenteric node metastasis was higher (P = 0.15). There was a trend for patients with positive mesenteric nodes to fail sooner (median survival, 20 months vs 32 months). CONCLUSIONS: Because ovarian carcinoma metastases to the gastrointestinal tract are frequently associated with metastases to mesenteric lymph nodes, gynecologic oncology surgeons may wish to consider resection of the mesentery in a wedge fashion similar to current standards of resection for primary bowel carcinoma in cases in which a bowel resection is being performed with the intent to debulk to zero visible residual disease.

First report of a vaginal foreign body perforating into the retroperitoneum.

Pelvic examination of a 19-year-old woman with recurrent pain after multiple laparotomies revealed a 4.0 cm paracervical fibroepithelial polyp and tender fullness in the left pelvis. Abdominal exploration had normal findings, but exploration of the retroperitoneum revealed an encysted bottle cap that had eroded through the vaginal wall years before.

Resection of a 303.2-pound ovarian tumor.

A woman with a 303.2-pound ovarian mass is presented. She had been bedridden for the previous 2 years and housebound for 6 years due to the enlarging mass. Psychological factors enabling this patient to remain home and sabotage attempts of her family to obtain help must be considered and dealt with while obtaining preoperative consultation with each of the services ultimately to be involved in the patient's care. Psychiatric, pulmonary, nutritional, cardiac, endocrinologic, reconstructive surgery, anesthesia, and operating room nursing assessment and advice should be sought. Despite the large size, there is a one-third chance of finding a malignancy, suggesting that all of these large masses should be removed intact whenever possible. An elliptical transverse incision from iliac crest to iliac crest offers the best preservation of abdominal wall anatomy and function. Invasive cardiac and pulmonary monitoring should continue through the operation and afterward, as severe cardiopulmonary/hemodynamic compromise is possible. Long-term psychiatric follow-up is needed as the dramatic anatomic restoration is not always accompanied by a similar psychologic restoration.

Documentation of complete resolution of gestational choriocarcinoma in the oophorectomized patient.

A 39-year-old woman with choriocarcinoma metastatic to the lungs and parametrium underwent total abdominal hysterectomy/bilateral salpingo-oophorectomy and follow-up chemotherapy with regression of the hCG assay, plateauing at 9 mIU/ml. Spinal fluid hCG assay was negative. An LH assay was performed which was 135 mIU/ml (2nd IRP-HMG). A quantitative hCG assay was performed on two sources of purified LH at varying concentrations to determine the contribution of LH cross-reactivity. When corrected for the LH contribution, the quantitative hCG was zero. Chemotherapy was discontinued. At 12-months follow-up the patient has remained in complete chemical remission and has an excellent performance status. Whenever a patient is oophorectomized, LH cross-reactivity should be ruled out as a cause for persistent low titers of hCG.

Principles of surgical management of ovarian carcinomas.

Nearly 80% of the approximately 20,000 women who develop ovarian carcinoma each year in the United States are diagnosed at stages II, III, or IV. The main goals of surgery in these patients are confirmation of diagnosis, accurate staging of the tumor, and reduction of tumor bulk. Among the topics discussed are intraoperative management, differential diagnosis by frozen section, pediatric tumors, ovarian carcinoma during pregnancy, second-look operations, and laparoscopic surgery.

Lymph node sampling in patients with epithelial ovarian carcinoma.

Lymph node sampling is part of the FIGO staging of patients with ovarian carcinoma and is usually part of a meticulous second look operation. We analyzed the primary lymph node status of patients and compared this to the lymph node status at second look operation. From 3/86-3/91, 97 patients with epithelial ovarian tumors were treated at this institution. Seventy-one of the 97 patients (73.2%) had lymph node sampling at primary surgery. Thirty of the 71 patients had positive lymph nodes (42.2%) and 41 patients were lymph node negative (57.8%). Of the initial 97 patients, 58 were eligible for second look operation (59.8%), and 48 of these patients had lymph nodes sampled at second look operation. Nine of the 48 patients had positive lymph nodes (18.7%) and 39 had negative lymph nodes at second look operation (81.3%). Of the patients with negative lymph nodes at primary surgery, 25 patients had second look operation and 24 of these patients had lymph node sampling at second look operation. All patients with negative lymph nodes at primary surgery had negative lymph nodes at second look operation. Of the 30 patients with positive lymph nodes at primary surgery, 12 underwent second look operation. Four patients had persistent positive lymph nodes and 8 patients had negative lymph nodes. Our data suggest that patients with negative lymph nodes at primary surgery are unlikely to have positive lymph nodes at second look operation. Therefore, we believe that lymph node sampling under these circumstances is unnecessary.

Adjuvant therapy for neuroendocrine small cell carcinoma of the cervix: review of the literature.

Neuroendocrine cell carcinoma of the cervix is a virulent tumor associated with an extremely poor prognosis. Even in clinical Stage I disease, there may be subclinical hematogenous and lymphatic metastases with frequent recurrences. Adjuvant postoperative external pelvic radiotherapy has been reported to offer some degree of local control; however, most patients succumb to distant disease. Following radical abdominal hysterectomy and pelvic lymphadenectomy, with confirmation of the neuroendocrine tumor by electron microscopy and immunohistochemical staining, two patients were given adjuvant systemic chemotherapy with concurrent pelvic radiotherapy, employing regimens with documented activity against small cell carcinoma of the lung of neuroendocrine origin. Despite severe myelotoxicity and persistent neuropathy, both patients are alive without clinical evidence of disease at 28+ and 47+ months.

Respiratory failure due to interstitial lung metastases of ovarian carcinoma reversed by chemotherapy.

A woman with metastatic ovarian carcinoma developed postoperative respiratory failure due to interstitial lung metastases demonstrated by bronchoalveolar lavage. After chemotherapy, she was able to be removed from mechanical ventilation and has shown progressive resolution of her interstitial lung disease. Metastatic ovarian carcinoma can be a treatable etiology of life-threatening interstitial lung disease.

CA-125: a potential prognostic indicator in patients with cervical cancer?

We evaluated 104 patients with newly diagnosed carcinoma of the cervix. Pre- and post-therapy and follow-up CA-125 levels were measured in 64 patients. Fifty-five patients (86%) had squamous cell carcinoma and 9 (14%) had adenocarcinoma of the cervix. At initial presentation 19 (30%) had CA-125 levels greater than 35 U/ml, 12 (19%) had levels of 16-35 U/ml, and 33 (51%) had levels less than 16 U/ml. Of the 11 patients who had pre- and post-treatment levels greater than 35 U/ml, 10 are dead of the disease and 1 is alive with persistent or recurrent disease. Of the 20 patients with elevated CA-125 levels at presentation who reverted to normal after therapy, 19 are clinically without evidence of disease at 14-46 months (median 27 months). Of the 33 patients with normal pre- and post-therapy CA-125 levels, 31 are clinically without evidence of disease. Two of these thirty-three patients had increasing CA-125 levels during routine follow-up and both have disease recurrence confirmed. There was no apparent correlation between CA-125 level and tumor type, tumor grade, or stage of disease. Our data suggest that patients with initially elevated CA-125 levels that revert to normal after therapy have a favorable prognosis. Persistent elevation of CA-125 levels during and after therapy in patients with carcinoma of the cervix was associated with a poor prognosis.

Virulence of papillary endometrial carcinoma.

While uterine papillary serous carcinoma (UPSC) has been well described as a virulent subtype of endometrial adenocarcinoma (AC), with behavior similar to that of papillary serous ovarian carcinoma, the papillary endometrial (PE) variant has not been well characterized. We studied 117 patients with endometrial carcinoma identified by our tumor registry, pathology files, and practice records from March 1981 to February 1989: 76 with AC, 26 with PE, and 15 with UPSC. Age and demographic data were similar for all three groups. All of the AC patients, 84% of PE patients, and 87% of UPSC patients had early-stage disease by clinical exam; however, 10% of AC patients, 23% of PE patients, and 87% of UPSC patients had extrauterine disease at surgery (P less than 0.05). Deep myometrial invasion occurred in 29% of AC patients, 36% of PE patients, and 60% of UPSC patients (P less than 0.05). Comparative analysis of the PE and UPSC groups revealed more marked nuclear anaplasia (P less than 0.05) and more frequent vascular space involvement (nonsignificant) in the UPSC group. At 3 years, 75% of the AC group was alive without disease. In contrast, the median progression-free interval for the PE group was 33 months, and for the UPSC group, 9 months (P less than 0.05). These data suggest a transition of increasing virulence corresponding with increasing papillary features, from AC to PE to UPSC. The papillary feature may be a new, significant risk factor in endometrial carcinoma.

Concomitant cisplatin and radiotherapy in locally advanced cervical carcinoma.

Patients with locally advanced cervical cancer have a poor prognosis. The efficacy of radiotherapy is limited by the presence of large tumor volume and nodal disease. As cisplatin is a documented radiosensitizer and has activity in squamous cell carcinomas, a prospective study was designed to evaluate the toxicity and potential synergism of concurrent cisplatin (20 mg/m2 x 5 d every 21 days) and radiotherapy in locally advanced cervical cancer. Forty-three patients were studied, of which 14 were stage IB/IIA (bulky disease) and 29 were stage IIB/IIIB/IVA. Of the 32 evaluable patients, there were 29 complete responders. Of these 29 patients, 27 remain without evidence of disease, with a median follow-up of 12 months. There were no treatment-related deaths. Cisplatin and radiotherapy appear to be a well-tolerated and highly effective regimen for locally advanced cervical cancer.
