Gynecologic Cancers

Clinicians, researchers, and survivorship communities are beginning to recognize the late effects of cancer treatment, such as infertility, and the negative impact this can have on cancer survivorship. Reproductive concerns that emerge within cancer experiences have been shown to be negatively associated with quality of life. Gynecologic cancer can present before childbearing has been started or completed, during pregnancy, or can even arise out of pregnancy, as is the case with gestational trophoblastic disease. Parenthood has been cited as an important aspect of cancer survivorship. As a result, interest concerning fertility preservation, reproductive concerns, and family-building options in cancer survivorship has increased, in addition to awareness of the emotional ramifications of cancer-related infertility. Education and support are clearly an essential component of cancer survivorship. Furthermore, more attention and investigation is still needed about the reproductive issues of gynecologic cancer survivors in the future.

For women with a gynecologic cancer, reproductive concerns may vary not only by site of disease but also by the presentation and manifestation of the disease. Gynecologic cancer can present before childbearing has been started or completed, during pregnancy, or can even arise out of pregnancy.

Intraperitoneal (IP) chemotherapy is a preferred treatment option that should be offered to all women for front-line treatment of stage III optimally debulked ovarian cancer. Patients should be provided with information on the survival and toxicity for both IP and intravenous (IV) therapies, as well as practical information about the administration of each regimen, so that they may play an active role in the decision-making process. When making a decision between IP and IV therapeutic options, the experience and preference of the oncologist are critical factors in determining appropriate therapy for each woman.

The review of the histology slides revealed predominantly decidual tissue with exaggerated placental site and a small focus of trophoblastic tissue composed of cytotrophoblast and syncytiotrophoblast with mild atypia (Figure 1). However, no necrosis or tissue invasion was identified. No villi were seen.

This article summarizes the current management of patients with newly diagnosed cervical cancer. The topics range from the management of early-stage disease to the phase III randomized studies that have established the current standard of care for patients with locally advanced cancer of the cervix. New approaches to combined-modality therapy with the goal of improving outcomes and decreasing complications are also described.

 I read with great interest the paper by Michael Brave and colleagues from the US Food and Drug Administration (FDA). The authors describe the FDA's review supporting this first approval of a chemotherapeutic drug for advanced cervical cancer. This decision was made after a Gynecologic Oncology Group trial (GOG-0179) conducted at 94 American study centers demonstrated a survival benefit in patients with stage IVB, recurrent, or persistent carcinoma of the cervix who received cisplatin plus topotecan (Hycamtin) compared with those who received cisplatin alone.

Topotecan, a camptothecin analog previously approved for the treatment of ovarian cancer and small-cell lung cancer, was granted regular approval by the US Food and Drug Administration (FDA) on June 14, 2006, for use in combination with cisplatin to treat women with stage IVB, recurrent, or persistent carcinoma of the cervix not amenable to curative treatment with surgery and/or radiation therapy. The purpose of this summary is to review the database supporting this approval.

The FDA has approved Merck's Gardasil (quadrivalent human papillomavirus recombinant vaccine) for the prevention of cervical cancer and cervical, vulvar, and vaginal precancers caused by human papillomarvirus (HPV).

The US Food and Drug Administration (FDA) has approved topotecan HCl (Hycamtin) in combination with cisplatin, for the treatment of stage IVB, recurrent, or persistent carcinoma of the cervix, which is not amenable to curative treatment with surgery and/or radiation therapy. Following a 6-month priority review by the FDA, the expanded indication is based on phase III results that demonstrated a survival advantage by using topotecan in combination with cisplatin compared to cisplatin alone.

Childbearing is one of the most important life goals for many women, and fertility preservation is a very important factor in the overall quality of life of cancer survivors. Cervical cancer frequently affects young women; because some women tend to delay childbearing, fertility preservation must be considered when treatment options are discussed. Over the past decade, the radical trachelectomy procedure has become a well established fertility-preserving option for young women with early-stage cancer; this procedure is associated with low morbidity, good oncologic outcome, and a high proportion of pregnancies that reach the third trimester and babies that are delivered at term. This article will review available literature on the vaginal radical trachelectomy procedure and data from other surgical approaches, such as the abdominal radical trachelectomy. In addition, the potential future application of neoadjuvant chemotherapy followed by fertility-preserving surgery in patients with locally advanced cervical cancer will be examined. Finally, ultraconservative surgical approaches (eg, conization alone with or without laparoscopic lymphadenectomy) in very early-stage disease will be discussed.

Over the past 2 decades, we have seen major progress in the management of women with ovarian cancer, with improvements in both overall survival and quality of life. To truly appreciate this progress, it is important to understand the state of affairs regarding the treatment of ovarian cancer in the early 1980s. This paper will discuss that historical background, describe the increasingly favorable impact of evolving treatment paradigms in ovarian cancer, and note future directions for clinical research in this complex disease process.

Endometrial cancer is the mostcommon gynecologic malignancyaffecting women in theUnited States. In 1988, the InternationalFederation of Gynecology andObstetrics shifted from a clinical stagingprotocol to one based on surgicalfactors, making surgical staging theaccepted treatment approach to endometrialcancers, with excellentsurvival compared to other gynecologicmalignancies. The manuscript byKirby et al brings to light the controversiessurrounding the surgical evaluationof endometrial cancers. Althoughsurgical staging has been shown to haveboth prognostic and therapeutic benefit,major problems in the United Statescontinue to result in suboptimal treatmentof patients with endometrial cancer.These problems include the lack ofan accepted surgical protocol (in termsof adequacy of lymph node sampling)and incomplete surgical staging secondaryto patient factors or the lack ofreferral to specialty-trained gynecologiconcologists.

Kirby et al are correct in theirstatement that continued controversysurrounds the comprehensivesurgical staging of all patientswith clinical stage I endometrialadenocarcinoma. Such is the case becauselymph node metastasis is foundin only 10% of these patients. Theproportion of patients found to havelymph node metastasis is even loweramong those with grade 1 and 2 tumorswith minimal or no invasion. Ahigh proportion of patients with endometrialadenocarcinoma fall intothis group.

Early presentation of endometrial cancer permits effective managementwith excellent clinical outcome. The addition of hysteroscopy todilatation and curettage (D&C) in the evaluation of postmenopausalbleeding adds little to the detection of malignancy. Imaging studies suchas computed tomography, magnetic resonance imaging, and positronemissiontomography may be of use in determining the presence ofextrauterine disease in patients medically unfit for surgical staging.However, these studies are not sufficiently sensitive to replace surgicalstaging and have little role in routine preoperative evaluation. Clinicalstaging alone is clearly inadequate, as 23% of preoperative clinicalstage I/II patients are upstaged with comprehensive surgical staging.Preoperative tumor grade from D&C or office biopsy may be inaccurateand lead to an underestimate of tumor progression if used to determinewhich patients should be surgically staged. Clinical estimationof depth of invasion, with or without frozen section, is inaccurate andmay lead to underestimation of disease status when surgical staging isnot performed. The practice of resecting only clinically suspicious nodesshould be discouraged as it is no substitute for comprehensive surgicalstaging. Comprehensive surgical staging provides proper guidance forpostoperative adjuvant therapy, avoiding needless radiation in 85% ofclinical stage I/II patients. Finally, resection of occult metastasis withsurgical staging may improve survival.

The review by Vergote et al[1]presents a well-organized andcomprehensive summary of thedata addressing neoadjuvant chemotherapyfor ovarian cancer. The timingof debulking surgery for thisdisease is a common and clinicallyimportant question, but one that lacksdefinitive trial data. The assembleddata suggest a rationale for decisionmaking.The European Organizationfor Research and Treatment of Cancer(EORTC) and Gynecologic OncologyGroup (GOG) 152 trialspresent compelling evidence supportinga “maximal surgical effort” by anexperienced gynecologic surgeon,preferably at a specialty hospital, atsome point during primary therapy.

Neoadjuvant, or induction, chemotherapyhas been usedextensively in selected carcinomas,particularly head andneck cancer (recently reviewed inONCOLOGY)[1] and locally advancedbreast cancer. Despite beneficialeffects on morbidity, long-termsurvival has not been significantly improvedby neoadjuvant chemotherapy.

Primary debulking surgery by a gynecologic oncologist remains thestandard of care in advanced ovarian cancer. Optimal debulking surgeryshould be defined as no residual tumor load. In retrospective analyses,neoadjuvant chemotherapy followed by interval debulking surgerydoes not seem to worsen prognosis compared to primary debulking surgeryfollowed by chemotherapy. However, we will have to wait for theresults of future randomized trials to know whether neoadjuvant chemotherapyfollowed by interval debulking surgery is as good as primarydebulking surgery in stage IIIC and IV patients. Interval debulking isdefined as an operation performed after a short course of induction chemotherapy.Based on the randomized European Organization for Researchand Treatment of Cancer–Gynecological Cancer Group (EORTC-GCG)trial, interval debulking by an experienced surgeon improves survival insome patients who did not undergo optimal primary debulking surgery.Based on Gynecologic Oncology Group (GOG) 152 data, intervaldebulking surgery does not seem to be indicated in patients who underwentprimarily a maximal surgical effort by a gynecologic oncologist.Open laparoscopy is probably the most valuable tool for evaluating theoperability primarily or at the time of interval debulking surgery.

Few would question the statementthat the role of surgery in themanagement of epithelial ovariancancer is unique in solid tumoroncology.
