Gynecologic Cancers

Diffusion-weighted MRI added to standard T2-weighted scans can help spot cervical cancer in its early stages. A preliminary study from the Institute of Cancer Research in London determined that DWI can spot tumors missed by T2 imaging and bolster management options for women who wish to preserve reproductive organs.

Patients with endometrial cancer who have minimally invasive robotic-assisted hysterectomies tend to have quicker surgeries and shorter hospital stays compared with patients who have similar laparoscopic surgical procedures, according to new research from The Ohio State University Comprehensive Cancer–James Cancer Hospital and Solove Research Institute.

BD Diagnostics recently announced that it received US Food and Drug Administration (FDA) Premarket Approval for the BD FocalPoint GS Imaging System.

Given that in the 21st century many believe 70 years of age is the new 60 and 80 years of age is the new 70, any article on ovarian cancer in the elderly depends on one’s definition of elderly. To put this in a 21st century perspective, in a thoughtful article on aging in The New Yorker (“The Way We Age Now,” April 30, 2007), Atul Gawande points out, “for most of our hundred-thousand-year existence-all but the past couple of hundred years-the average life span of human beings has been 30 years or less (research suggests that subjects of the Roman Empire had an average life expectancy of 28 years).

Conventional therapy for advanced-stage ovarian cancer-ie, aggressive cytoreductive surgery followed by aggressive chemotherapy-was established more than 3 decades ago [Editor’s note: See Dr. Schwartz’s article, “Cytoreductive Surgery in the Management of Ovarian Cancer,” in last month’s issue of ONCOLOGY]. Since that time, no prospective randomized trials have been reported to confirm the efficacy of this treatment strategy.

The standard management for advanced-stage ovarian cancer was established in the mid-1970s. At a 1974 National Cancer Institute Consensus Conference on Ovarian Cancer, Griffiths presented data supporting the role for aggressive cytoreductive surgery as the first step in the management of this disease, followed by cytotoxic chemotherapy.

The first phase III study of its kind has found that vaginal brachytherapy—in which a radioactive cylinder is inserted into the vagina—is as effective at preventing the recurrence of higher-risk endometrial cancer as external-beam radiation therapy, has fewer side effects, and results in a better quality of life for patients (abstract LBA5503).

Although vulvar cancer is relatively rare, accounting for less than 5% of all cancers of the female genital organs, lymph node metastasis associated with vulvar carcinoma is a common event and occurs in about 25% of cases.[1] The presence and number of lymph node metastases is the single most important prognostic factor in vulvar cancer and a critical component to the International Federation of Gynecology and Obstetrics (FIGO) staging system, as well as a major determinant in the need for adjuvant therapy

Halsted first proposed the concept of "radical surgery" for cancer in 1882, theorizing that cancer, along with all of its supporting tissues and regional lymph nodes, needs to be removed en bloc for the best chance of cure. Radical mastectomy with en bloc removal of the axillary nodes and pectoral muscles became the standard treatment for breast cancer. En bloc radical vulvectomy with complete superficial and deep inguniofemoral lymph node dissection became the standard of care for vulvar cancer. Subsequently, unilateral or bilateral pelvic node dissection extended the scope of the regional node dissection for vulvar cancer patients with metastases to groin nodes. Unquestionably, this surgically comprehensive technique improved cancer control rates for patients with locally extensive vulvar cancer, compared to results from piecemeal approaches that characterized surgical therapy in prior eras.

Over the past 15 years, lymphatic mapping and sentinel lymph node biopsy in vulvar, vaginal, and cervical cancers have been explored by gynecologic oncologists around the world. Based on the results of multiple single-institution studies, most in our field are optimistic that these techniques will increase the rates of detection of lymph node metastasis while decreasing the morbidity associated with lymphadenectomy. Large validation studies are currently underway in both the United States and Europe. In this review article, we present the published data on mapping techniques and discuss future considerations for these technologies.

Merck & Co recently announced that the US Food and Drug Administration (FDA) has accepted, and designated for priority review, the supplemental Biologics License Application (sBLA) for its recombinant human papillomavirus quadrivalent vaccine (Gardasil) for potential use in women aged 27 through 45.

Phase III data showed that at 18 months after the first of a three-dose regimen, 100% of women up to age 55 vaccinated with the GlaxoSmithKline (GSK) cervical cancer candidate vaccine (Cervarix) had antibodies present against the two most common cancer-causing human papillomavirus types, 16 and 18

Merck & Co., Inc. has committed to donate at least 3 million doses of quadrivalent human papillomavirus (HPV types 6, 11, 16, 18) recombinant vaccine (Gardasil), the cervical cancer vaccine, for use in demonstration projects in lowest-income nations throughout the world.

The New England Journal of Medicine recently published results from two phase III studies of Merck's cervical cancer vaccine, Gardasil [quadrivalent human papillomavirus (types 6, 11, 16, 18) recombinant vaccine].

Vaccines designed to protect against human papillomavirus (HPV)—and thus protect against cervical cancer—are showing sustained protection at 5 years

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.
