In this installment of Second Opinion, we are presenting two cases of tumors of the female genital tract, specifically, the ovary and uterus, which contain both epithelial and mesenchymal components and therefore have unique diagnostic and therapeutic implications. The first has an unusually poor prognosis and the second is notoriously difficult to diagnose.
Ovarian cancer is the deadliestof the gynecologic malignancies.Approximately threequartersof patients present with advanced-stage disease. With aggressivecytoreductive surgery followed byplatinum-based chemotherapy, mostpatients will achieve remission. Despitethis initially good response totreatment, most patients experiencerecurrence and ultimately die of theirdisease. Novel treatment strategies areneeded. Molecularly targeted therapiesoffer the promise of improvedefficacy with decreased toxicity. Inthis article, Drs. Stephanie Blank, RichardChang, and Franco Muggiapresent an excellent summary of thecurrent status of epidermal growth factorreceptor (EGFR) inhibitors in thetreatment of ovarian cancer. They describethe promise of these drugs aswell as some of the questions regardingthe best way to integrate theminto therapy for ovarian cancer.
The 14 reports in this special supplement discuss theuse of the cytoprotectant amifostine in patients withcancer of the head and neck, esophagus, lung, andcervix, as well as those with lymphoma and acutemyelogenous leukemia. Discussions focus on thepotential of this agent to both reduce radiation sideeffects such as xerostomia and permit doseescalation of chemotherapy and/or radiotherapy.Improvements in treatment outcome and quality oflife as a result of cytoprotection are examined.

SAN DIEGO-For the first time, a combination regimen has shown improved survival over single-agent cisplatin (Platinol) for the treatment of advanced cervical cancer, according to the Gynecologic Oncology Group (GOG) protocol 179, which was presented at the 35th Annual Meeting of the Society of Gynecologic Oncologists (abstract 9).
A review of sentinel node mapping in vulvar and cervical cancer, a technique intended to reduced lymphadenectomy-associated morbidity, and the related controversies.
Iwould like to compliment the authorson an excellent review ofsentinel node evaluation in gynecologiccancer-in particular, vulvarand cervical cancer. The authors havebeen at the forefront of minimally invasivesurgery for gynecologicmalignancies. They have publishedextensively about their experiencewith laparoscopy and radical trachelectomy.Now this group brings forthanother technique that may revolutionizethe way we treat women withvulvar and cervical carcinoma.
By a long-standing strategy,practitioners have sought tolessen the morbidity associatedwith the treatment of pelvic malignancies.With careful understandingof pathologic prognostic factors andthe natural histories of recurrence andmetastatic disease, as well as improvementof imaging studies, there hasbeen a significant reduction in the radicalityof gynecologic surgery.[1-3]
Cervical cancer rates have fallen in the United States; regardless, thedisease remains a significant concern for women, especially those whoare premenopausal. The management of cervical cancer is dependenton stage of disease at diagnosis, and specific needs emerge for patientsboth during and following treatment. Over the past decade, the focus hasbeen to maintain adequate tumor control while reducing long-termnegative consequences. However, problems with sexuality and fertilitypersist for women treated for cervical cancer despite these advances.Sexual dysfunction following treatment for gynecologic cancer hasbeen well documented in the literature, and recent studies demonstratethe success of brief psychosexual interventions. Treatment of sexualdifficulties in cancer patients can be achieved through the provision ofinformation, support, and symptom management, ideally as part of asexual health program. Resources are not always available to developsuch a program. However, medical professionals can identify individualsand organizations with expertise in treating sexual and fertilityconcerns, which can be provided to their patients, making help withthese problems more accessible as needs arise.
Carter et al provide a nice summaryof current knowledge ofsexual dysfunction in and rehabilitationof women with invasivecervical cancer. The prevailing perspectiveof their review, however,seems to be that most women treatedfor cervical cancer are white, middleclasspatients at major cancer centers.In order to make a difference in thequality of life of the majority of cervicalcancer survivors, we have to understandwho they are and recognizethe impact of social and gender inequalityon their lives and relationships.
The importance of quality of lifeduring and after treatment forcervical cancer has been ignoredfor too long. The pervasive attitudethat focuses on cure, withmorbidity an afterthought, is stillparamount in many patients’ and oncologists’minds. However, at the insistenceof patients and families, manyclinicians have recognized and startedto address these issues over thepast 2 decades.
NEW ORLEANS-In women with locally advanced cervical cancer, smoking is an independent risk factor for a significantly worse outcome, a new study from the Gynecologic Oncology Group (GOG) has shown.
ROCKVILLE, Maryland-Physicians can discontinue cervical cancer screening for many women age 65 and older, and delay screening for some young women until age 21, according to new guidelines developed by the US Preventive Services Task Force (USPSTF).
During 1973–1999, both the incidenceof and death rates forcervical cancer decreased byapproximately 50% in the UnitedStates. For 2002, approximately13,000 new cases of invasive cervicalcancer are expected, and approximately4,100 women will die of the disease.Although invasive cervical cancer canbe prevented by regular screening, theprevalence of Pap testing remains relativelylow among minority populationssuch as Hispanic women.
NEW ORLEANS-In the treatment of locoregionally advanced cervical cancer, the addition of cisplatin (Platinol)-containing chemotherapy to a radiation therapy regimen significantly improves overall and disease-free survival, according to RTOG 90-01. Patricia J. Eifel, MD, of the Department of Radiation Oncology, M.D. Anderson Cancer Center, presented the data at the American Society for Therapeutic Radiology and Oncology plenary session (abstract plenary 1).
CHICAGO-Adding paclitaxel (Taxol) and G-CSF support to the standard regimen of doxorubicin and cisplatin (Platinol) improved response rates and increased survival by about 3 months for patients with advanced or recurrent endometrial cancer in a randomized controlled phase III trial conducted by the Gynecologic Oncology Group (GOG) (ASCO abstract 807).
Dr. Grigsby has done a masterful job of summarizing current information on the use of radiation in the management of patients with endometrial carcinoma. In the summary, he offers clear recommendations as to the appropriate management of various subsets of patients-recommendations that are based, at least to some extent, on the data reviewed. Such decision-making based on often incomplete information is necessary in the absence of appropriately designed randomized trials addressing the specific clinical situation. It is important, however, to understand clearly what we actually know and what we deduce from bits and pieces of data.
Dr. Grigsby does an excellent job of summarizing the accepted, stage-by-stage treatment recommendations as well as the controversies surrounding the treatment of endometrial carcinoma. This review is both important and timely, as we have seen the incidence of endometrial cancer increase over the past few years to the point where it is now the most common gynecologic malignancy.
The best clinical outcomes for patients with endometrial cancer seem to be achieved with either surgery alone or a combination of surgery and radiation therapy. Although once administered preoperatively, irradiation is now
Topoisomerase inhibitors have been widely studied for the treatment of refractory or recurrent cervical cancer. Various schedules have been used, with response rates ranging from 13% to 20%. The combination of cisplatin and irinotecan (CPT-11, Camptosar) is being studied in cervical cancer.
WASHINGTON-Health and Human Services Secretary Tommy Thompson has given nine more states the go-ahead to extend Medicaid benefits to uninsured women diagnosed with cancer under the federal Breast and Cervical Cancer Prevention and Treatment Act of 2000.
HOUSTON, Texas-Irinotecan (Camptosar) is active in platinum-refractory cervical cancer and should be tested with cisplatin (Platinol) in randomized trials, declared Claire F. Verschraegen, MD. The use of irinotecan might enable clinicians in developing countries (where radiotherapy equipment is in short supply) to downsize many cervical cancers to resectable size, Dr. Verschraegen added. She is assistant professor in the Division of Cancer Medicine Section of Gynecologic and Medical Therapeutics at the University of Texas M. D. Anderson Cancer Center in Houston, Texas.
CHICAGO-Cisplatin-based chemoradiotherapy has greater efficacy than previous regimens in treating cervical cancer, but toxicity needs to be reduced, stated William Small, Jr., MD. He is assistant professor of radiology, Division of Radiation Oncology, at Northwestern University’s Robert H. Lurie Comprehensive Cancer Center in Chicago.
The diagnosis and management of cancer in older women is becoming an increasingly common and challenging issue. Women who reach age 65 can expect to live an additional 17 years.[1] Age is an important risk factor for developing cancer. Epidemiologic data from 1992 to 1994 reveal that invasive cancer develops in 1 of 5 women aged 60 to 79 years.[2]
WASHINGTON-A new analysis of data from the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) shows that among women who received their first NBCCEDP Pap test between 1991 and 1998, American Indian and Alaskan Native (AI/AN) women had the highest proportion of abnormal Pap tests, while white women had the highest rate of serious cervical lesions detected by biopsy.
