Endometriosis-associated invasive adenocarcinoma involving the rectum in a postmenopausal female: report of a case.

Sampson first reported a case of malignant transformation of endometriosis to adenocarcinoma in 1925. We present a case of such transformation occurring in a postmenopausal female 22 years after total abdominal hysterectomy and bilateral salpingo-oophorectomy. This case demonstrates histologic progression from endometriosis to complex hyperplasia with cytologic atypia, and ultimately to invasive endometrioid adenocarcinoma involving the rectum. Aggressive surgical extirpation of all visible colorectal endometriosis for patients with advanced disease is recommended.

Endometriosis: correlation between histologic and visual findings at laparoscopy.

OBJECTIVE: The purpose of this study was to correlate the diagnosis of endometriosis on the basis of visualization at laparoscopy with the pathologic diagnosis. STUDY DESIGN: A prospective study of 44 patients undergoing laparoscopy for the evaluation of chronic pelvic pain was carried out. All areas suggestive of endometriosis were excised and examined pathologically. Peritoneal biopsy specimens were obtained from areas of normal-appearing peritoneum to rule out microscopic endometriosis. All lesions were identified by anatomic site. Visual and histologic American Fertility Society scores were compared. The positive predictive value, sensitivity, negative predictive value, and specificity were determined for visually identified endometriosis versus the histologic correlate. RESULTS: The mean prevalence of abnormalities visually consistent with endometriosis was 36%, with 18% confirmed histologically. The positive predictive value was 45%; sensitivity, 97%; negative predictive value, 99%; and specificity, 77%; for visual versus histologic diagnosis of endometriosis. Thirty-six percent of the diagnoses were downstaged on the basis of histologic findings. CONCLUSION: A diagnosis of endometriosis should be established only after histologic confirmation.

Flow-cytometric DNA analysis of early stage adenocarcinoma of the cervix.

OBJECTIVE: The purpose of this study was to determine the utility of DNA flow cytometry as a prognostic indicator for risk of recurrence and overall survival in patients with early stage adenocarcinomas of the uterine cervix. METHODS: DNA flow cytometry was performed to determine ploidy, DNA index, and proliferative index in 66 women with stages IB and IIA pure mucinous adenocarcinomas of the cervix treated by primary surgical therapy with radical hysterectomy and pelvic lymphadenectomy. Fifty-seven of 66 (86.3%) tissue samples were analyzable. Three sections were obtained from paraffin-embedded tissue blocks containing primary tumor. Flow-cytometric results, along with other known prognostic variables for risk for recurrent disease and survival, were analyzed using Cox regression proportional hazards model, and survival curves were generated by the Kaplan-Meier method. RESULTS: Of 57 interpretable samples, DNA ploidy patterns were 18 (27%) diploid, 8 (12%) tetraploid, and 31 (47%) aneuploid. Thirteen of 66 patients (20%) experienced recurrence with a median time to recurrence of 1.6 years. No significant correlation was noted between DNA ploidy and risk of recurrence (P = 0.429). Multivariate analysis confirmed that positive metastatic lymph nodes were associated with risk of recurrence (P < 0.001). In node-negative patients, a high proliferative index (S% + G(2)M% > 20%), measured as a continuous variable, was the only significant factor for tumor recurrence (P = 0.002). CONCLUSION: DNA ploidy does not predict a patient's risk for tumor recurrence; however, a high proliferative index value warrants further investigation as a potential prognostic indicator for risk of recurrent disease in patients with adenocarcinoma of the uterine cervix.

Laparoscopic lymphadenectomy and vaginal or laparoscopic hysterectomy with bilateral salpingo-oophorectomy for endometrial cancer: morbidity and survival.

OBJECTIVES: Our goal was to evaluate the morbidity, recurrence, and survival of patients with clinical stage I endometrial cancer treated by laparoscopic lymphadenectomy with vaginal or laparoscopic hysterectomy and bilateral salpingo-oophorectomy. STUDY DESIGN: This article is a retrospective review of records for 56 patients. The mean follow-up among those alive at last contact was 2.4 years (range, 32 days-5.2 years). Staging according to the International Federation of Gynecology and Obstetrics (1988) was as follows: I, 45 (80.4%); II, 3 (5.4%); III, 6 (10.7%); and IV, 2 (3.6%). RESULTS: Intraoperative complications occurred in 4 patients (7.1%). Transformation to laparotomy was necessary in 7 patients. Postoperative complications were observed in 9 patients (16.1%). Pelvic irradiation was administered postoperatively to 11 patients (19.6%). Among the 45 patients with surgical stage I disease, the 3-year recurrence rate was 2.5% and the 3-year cause-specific survival was 96.0%. CONCLUSIONS: Laparoscopic lymphadenectomy and vaginal or laparoscopic hysterectomy with bilateral salpingo-oophorectomy provided 3-year survival and recurrence rates similar to those of the traditional abdominal approach.

Misoprostol as a labor induction agent.

The objective of this investigation was to compare the efficacy, safety, and cost of intravaginal misoprostol as a labor induction agent to a standard protocol using prostaglandin E2 (Prepidil) and intravenous oxytocin. Thirty-eight patients requiring induction of labor with an unfavorable cervix (Bishop score < or = 5) were prospectively randomized to receive either 50 mcg misoprostol every 4 hours until delivery, or a single dose of PGE2 gel (0.5 mg) followed by intravenous oxytocin infusion. Changes in Bishop scores were recorded in a blinded fashion. Clinical outcomes were compared in the two groups, including induction-to-delivery times and cesarean section rates. Seventeen women were treated with misoprostol, 19 patients received PGE2/oxytocin, and two patients dropped out of the study. The groups did not differ significantly with respect to age, parity, gestational age, weight, height, reason for induction, or initial Bishop score. There was a significant difference in the median change of the Bishop score among those treated with misoprostol (4) and those of the control group (1) (P < 0.001). Fifteen (88%) receiving misoprostol delivered within 36 hours compared with 9 (47%) of controls (P = 0.01). Significantly more women in the misoprostol arm (8) experienced tachysystole when compared with the control group (0) (P < 0.01). There were no perinatal morbidities in either group. These data support misoprostol as an effective and economical cervical-ripening and labor-inducing agent.

Aggressive angiomyxoma of the female pelvis and perineum: a case series.

Aggressive angiomyxoma (AA) was first described in 1983, and fewer than 150 cases have been reported in the world medical literature. These tumors are benign, locally infiltrative mesenchymal neoplasms with a predilection for the female pelvis and perineum and a tendency to recur. The size of AAs at presentation varies considerably; however, these tumors often achieve large dimensions before becoming clinically symptomatic. Surgical excision remains the mainstay of treatment, but whether clear, tumor-free surgical margins are necessary is controversial. We report a cohort of six patients treated surgically during the past 20 years for primary or recurrent AA. Treatment, surgical margin status, estrogen and progesterone receptor status, and outcomes are reviewed.
