Molecular imaging through positron emission tomography (PET) is playing a very important role in the management of several different cancers. Its noninvasive nature and ability to study biologic function are ideal for oncology practice. PET is establishing itself in staging, guiding therapy, and follow-up of patients with cervical cancer. The emergence and widespread availability of combined PET/computed tomography technology has further consolidated the role of molecular scanning in managing these patients. This technology is now accessible to every cancer center in the United States and is also available in most countries. Although it is approved for staging patients with cervical cancer, its use in other clinical management situations is being evaluated. The real power of molecular imaging will be to predict treatment response and guide therapy and applications of novel PET tracers for studying complex cellular functions that characterize the tumor for individualized treatment approaches. Although PET technology is beyond the reach of many developing countries, the experience gained in major centers would help devise more effective and simpler treatments that can be introduced.

For the first time, NCCN Guidelines are available for vulvar cancer, a rare gynecologic cancer. Early-stage cancers can be managed by surgery and observation, and many of these patients can be cured. Lymph node status drives treatment and correlates with survival. Positive groinal nodes require additional therapy, including radiation plus chemotherapy, depending on stage. Sentinel lymph node biopsy is recommended in selected patients.

Ovarian cancer is the second most common gynecologic cancer in women and the leading cause of death caused by gynecologic malignancy. Surgery plays a fundamental role in treating this challenging disease. Goals of primary surgery for ovarian cancer are to establish diagnosis, proper staging, determination of prognosis, and optimal cytoreduction of gross disease before chemotherapy for improved outcome. In addition to standard removal of the ovaries, uterus, omentum, and pelvic and para-aortic lymph nodes for early disease, extended surgical techniques used to debulk advanced disease include bowel resection, splenectomy, partial liver resection, peritoneal or diaphragmatic stripping, and use of laser or ultrasound (CUSA). Secondary surgery is used in a variety of situations. Second-look procedures were performed historically to determine response to chemotherapy to delineate duration of treatment, but now are best used in a research setting with the advent of improved chemotherapeutic agents. As a high percentage of patients have a gynecologic malignancy recurrence after primary treatment, many practitioners perform secondary cytoreductive procedures for recurrent disease. Additionally, in the recurrent setting, surgery may be necessary for relief of bowel obstruction and palliation of symptoms. Surgical management of ovarian cancer must be performed by surgeons, such as gynecologic oncologists, who have a firm understanding of the disease process, display good clinical judgment, and are adequately trained to perform the complex surgery that commonly is required for appropriate care.

More than 14 million new cancer cases and 8.2 million cancer deaths are estimated to occur worldwide on an annual basis. Of these, 57% of new cancer cases and 65% of cancer deaths occur in low- and middle-income countries. Disparities in available resources for health care are enormous and staggering. The WHO estimates that the United States and Canada have 10% of the global burden of disease, 37% of the world's health workers, and more than 50% of the world's financial resources for health; by contrast, the African region has 24% of the global burden of disease, 3% of health workers, and less than 1% of the world's financial resources for health. This disparity is even more extreme with cancer. NCCN has developed a framework for stratifying the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) to help health care systems in providing optimal care for patients with cancer with varying available resources. This framework is modified from a method developed by the Breast Health Global Initiative. The NCCN Framework for Resource Stratification (NCCN Framework) identifies 4 resource environments: basic resources, core resources, enhanced resources, and NCCN Guidelines, and presents the recommendations in a graphic format that always maintains the context of the NCCN Guidelines. This article describes the rationale for resource-stratified guidelines and the methodology for developing the NCCN Framework, using a portion of the NCCN Cervical Cancer Guideline as an example.

Adenocarcinoma of the endometrium (also known as endometrial cancer or more broadly as uterine cancer or carcinoma of the uterine corpus) is the most common malignancy of the female genital tract in the United States. An estimated 49,560 new uterine cancer cases will occur in 2013, with 8190 deaths resulting from the disease. Uterine sarcomas (stromal/mesenchymal tumors) are uncommon malignancies, accounting for approximately 3% of all uterine cancers. The NCCN Guidelines for Uterine Neoplasms describe malignant epithelial carcinomas and uterine sarcomas; each of these major categories contains specific histologic groups that require different management. This excerpt of these guidelines focuses on early-stage disease.

These NCCN Clinical Practice Guidelines in Oncology for Cervical Cancer focus on early-stage disease, because it occurs more frequently in the United States. After careful clinical evaluation and staging, the primary treatment of early-stage cervical cancer is either surgery or radiotherapy. These guidelines include fertility-sparing and non-fertility-sparing treatment for those with early-stage disease, which is disease confined to the uterus. A new fertility-sparing algorithm was added for select patients with stage IA and IB1 disease..

Vulvar cancer is a rare gynecologic malignancy. Ninety percent of vulvar cancers are predominantly squamous cell carcinomas (SCCs), which can arise through human papilloma virus (HPV)–dependent and HPV-independent pathways. The NCCN Vulvar Cancer panel is an interdisciplinary group of representatives from NCCN Member Institutions consisting of specialists in gynecological oncology, medical oncology, radiation oncology, and pathology. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Vulvar Cancer provide an evidence- and consensus-based approach for the management of patients with vulvar SCC. This manuscript discusses the recommendations outlined in the NCCN Guidelines for diagnosis, staging, treatment, and follow-up.

The NCCN Guidelines for Uterine Neoplasms provide interdisciplinary recommendations for treating endometrial carcinoma and uterine sarcomas. These NCCN Guidelines Insights summarize the NCCN Uterine Neoplasms Panel's 2016 discussions and major guideline updates for treating uterine sarcomas. During this most recent update, the panel updated the mesenchymal tumor classification to correspond with recent updates to the WHO tumor classification system. Additionally, the panel revised its systemic therapy recommendations to reflect new data and collective clinical experience. These NCCN Guidelines Insights elaborate on the rationale behind these recent changes.
