Effective treatment of stage I uterine papillary serous carcinoma with high dose-rate vaginal apex radiation (192Ir) and chemotherapy.

PURPOSE: Uterine papillary serous carcinoma (UPSC) is a morphologically distinct variant of endometrial carcinoma that is associated with a poor prognosis, high recurrence rate, frequent clinical understaging, and poor response to salvage treatment. We retrospectively analyzed local control, actuarial overall survival (OS), actuarial disease-free survival (DFS), salvage rate, and complications for patients with Federation International of Gynecology and Obstetrics (FIGO) (1988) Stage I UPSC. METHODS AND MATERIALS: This retrospective analysis describes 38 patients with FIGO Stage I UPSC who were treated with the combinations of radiation therapy, chemotherapy, total abdominal hysterectomy, and bilateral salpingo-oophorectomy (TAH/BSO), with or without a surgical staging procedure. Twenty of 38 patients were treated with a combination of low dose-rate (LDR) uterine/vaginal brachytherapy using 226Ra or 137Cs and conventional whole-abdomen radiation therapy (WART) or whole-pelvic radiation therapy (WPRT). Of 20 patients (10%) in this treatment group, 2 received cisplatin chemotherapy. Eighteen patients were treated with high dose-rate (HDR) vaginal apex brachytherapy using 192Ir with an afterloading device and cisplatin, doxorubicin, and cyclophosphamide (CAP) chemotherapy (5 of 18 patients). Only 6 of 20 UPSC patients treated with combination LDR uterine/vaginal brachytherapy and conventional external beam radiotherapy underwent complete surgical staging, consisting of TAH/BSO, pelvic/para-aortic lymph node sampling, omentectomy, and peritoneal fluid analysis, compared to 15 of 18 patients treated with HDR vaginal apex brachytherapy. RESULTS: The 5-year actuarial OS for patients with complete surgical staging and adjuvant radiation/chemotherapy treatment was 100% vs. 61% for patients without complete staging (p = 0.002). The 5-year actuarial OS for all Stage I UPSC patients treated with postoperative HDR vaginal apex brachytherapy and systemic chemotherapy was 94% (18 patients). The 5-year actuarial OS for Stage I UPSC patients treated with HDR vaginal apex brachytherapy and chemotherapy who underwent complete surgical staging was 100% (15 patients). The 5-year actuarial OS for the 20 Stage I UPSC patients treated with combinations of pre- and postoperative LDR brachytherapy and postop WART was 65%. None of the 6 surgically staged UPSC patients treated with LDR radiation and WART/WPRT developed recurrent disease. For patients with FIGO Stage IA, IB, and IC UPSC who underwent complete surgical staging, the 5-year actuarial DFS by depth of myometrial invasion was 100, 71, and 40%, respectively (p = 0.006). The overall salvage rate for local and distant recurrence was 0%. Complications following HDR vaginal apex brachytherapy included only Radiation Therapy Oncology Group (RTOG) grade 1 and 2 toxicity in 16% of patients. However, complications from patients treated with WART/WPRT, and/or LDR brachytherapy, included RTOG grade 3 and 4 toxicity in 15% of patients. CONCLUSION: Patients with UPSC should undergo complete surgical staging, and completely surgically staged FIGO Stage I UPSC patients can be effectively and safely treated with HDR vaginal apex brachytherapy and chemotherapy. Both OS and DFS of patients with UPSC are dependent on depth of myometrial invasion. The salvage rate for both local and distant UPSC recurrences is extremely poor. Complications from HDR vaginal apex brachytherapy were minimal.

Operative laparoscopy and the gynecologic oncologist. Commentary and review.

BACKGROUND: A rapid evolution in technology and surgical applications of endoscopy have occurred over the past 5 years. Surgical procedures once thought impossible except through large abdominal incisions are being performed with the use of laparoscopic surgical techniques. Laparoendoscopic techniques have limitations as well as advantages over conventional surgical approaches. METHODS: The medical literature as it relates to laparoscopy and gynecologic oncology was reviewed. RESULTS: Procedures performed through the laparoscope include total hysterectomies, bilateral oophorectomies, pelvic and periaortic lymphadenectomies, omentectomies, colostomies, bowel resections, oophoropexies, and pelvic lid constructions as well as radical hysterectomies and ovarian cancer debulking procedures. These techniques are gaining popularity among gynecologic oncologists, and studies of individual case reports have been followed by studies involving a series of patients. Numerous limiting factors exist, however, foremost among these being the wide variability of endoscopic skills among surgeons and lack of objective long term data supporting the efficacy and safety of these techniques. CONCLUSION: Application of endoscopic techniques in gynecologic oncology procedures is occurring rapidly and is driven partly by market economy forces. Many gynecologic oncologists, however, do not have the necessary endoscopic skills and experience with which to perform such procedures. For these physicians to remain sufficiently qualified, fellowship training programs must encompass formal training curricula in endoscopic surgery, and such programs should often include the faculty as well. Formal and organized credentialing of laparoscopic cancer surgical expertise will ensure a minimum safe level of skills.

The role of laparoscopy in the management of gynecologic malignancy.

With the advent of minimally invasive laparoscopic techniques, most gynecologic procedures for benign conditions can be performed in an outpatient setting. However, the role of such techniques in gynecologic oncology is not well defined. By reviewing the literature and presenting some new data, we attempt to elucidate the applications of operative videolaparoscopy in gynecologic oncology. Advanced laparoscopic techniques are utilized for the management of cervical cancer as well as the staging and treatment of endometrial and ovarian cancers. Such techniques are used in performing radical hysterectomy for early stage cervical cancer, pelvic and paraaortic lymphadenectomy, and second look laparoscopy following chemotherapy for ovarian cancer. Even though preliminary data are encouraging, large prospective controlled studies with long-term follow-up are necessary to better define the role and limitations of laparoscopy in the treatment of gynecologic malignancies.

Ovarian hyperstimulation syndrome in the emergency department: a case report.

The Ovarian Hyperstimulation Syndrome (OHSS) is a complication of ovulation enhancing technologies that is becoming more prevalent with increasing use of these techniques in infertile women. In this report, we describe a 36-year-old woman who presented to the Emergency Department with hemodynamic compromise secondary to OHSS. The OHSS is characterized by ovarian enlargement, ascites, electrolyte disturbances, hypotension, and thromboembolic events. This case illustrates a serious complication of techniques used to enhance fertility.
