Radiation therapy plays an important role in both the definitive and adjuvant treatment of patients with cervical cancer. However, although radiation therapy is effective in controlling tumor growth, associated acute and chronic adverse effects are well known. Intensity-modulated radiation therapy (IMRT) is increasingly being used to treat cervical cancer and has the potential to improve the therapeutic ratio because of its ability to escalate dose to cancer targets while sparing adjacent healthy tissue. Multiple dosimetric studies were initially performed, establishing the conceptual feasibility of IMRT in patients with cervical cancer. Subsequent early reported series of patients treated with IMRT showed dosimetric and clinical benefits, with reduction in acute gastrointestinal and hematologic toxicity compared with historic controls, particularly in the posthysterectomy setting. Consensus is evolving regarding the use of IMRT in treating cervical cancer, particularly in the posthysterectomy setting, and for dose escalation to para-aortic nodes and bulky sidewall disease. Target delineation in the context of internal organ motion and tumor shrinkage during a course of fractionated external-beam radiotherapy remains an area of active investigation. IMRT in treating cervical cancer in the setting of an intact uterus remains in its nascent stage and should be used judiciously only within clinical trials. Although not a routine substitute for brachytherapy, it may be considered as a boost for highly selected patients who are not brachytherapy candidates.

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.

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.

Uterine Neoplasms Clinical Practice Guidelines in OncologyNCCN Categories of Evidence and ConsensusCategory 1: The recommendation is based on high-level evidence (e.g., randomized controlled trials) and there is uniform NCCN consensus.Category 2A: The recommendation is based on lowerlevel evidence and there is uniform NCCN consensus.Category 2B: The recommendation is based on lowerlevel evidence and there is nonuniform NCCN consensus (but no major disagreement).Category 3: The recommendation is based on any level of evidence but reflects major disagreement.All recommendations are category 2A unless otherwise noted.Clinical trials: The NCCN believes that the best management for any cancer patient is in a clinical trial. Participation in clinical trials is especially encouraged.OverviewAdenocarcinoma of the endometrium is the most common malignancy in the female genital tract in the United States. An estimated 40,100 new diagnoses of uterine cancer and 7470 deaths from this disease will occur in 2008.1 Uterine sarcomas are uncommon and account for approximately 1 in 12 of all uterine cancers.2 These guidelines describe epithelial carcinomas and uterine sarcomas; each of these major categories contains specific histologic groups that require different management (see page 500).By definition, these guidelines cannot incorporate all possible clinical variations and are not intended to replace good clinical judgment or individualization of treatments. Exceptions to the rule were discussed among panel members during the process of developing these guidelines.For patients with suspected uterine neoplasms, initial preoperative evaluation includes a history and physical examination, endometrial biopsy, chest radiograph, a CBC,...

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..

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.

OverviewAn estimated 12,200 new cases of cervical cancer will be diagnosed in the United States in 2010, and 4200 people will die of the disease.1 Cervical cancer rates are decreasing among women in the United States, although incidence remains high among Hispanic/Latino, black, and Asian women.2–5 However, cervical cancer is a major world health problem for women. The global yearly incidence of cervical cancer for 2002 was 493,200; the annual death rate was 273,500. It is the third most common cancer in women worldwide,6,7 with 78% of cases occurring in developing countries, where cervical cancer is the second most frequent cause of cancer death in women.Persistent human papillomavirus (HPV) infection is regarded as the most important factor contributing to the development of cervical cancer. A relationship seems to exist between the incidence of cervical cancer and the prevalence of HPV in the population. The prevalence of chronic HPV in countries with a high incidence of cervical cancer is 10% to 20%, whereas its prevalence in low-incidence countries is 5% to 10%.6 Immunization against HPV prevents infection with certain types of HPV and, thus, is expected to prevent specific HPV cancer in women (see NCCN Clinical Practice Guidelines in Oncology [NCCN Guidelines] for Cervical Cancer Screening, in this issue; to view the most recent version of these guidelines, visit the NCCN Web site at www.NCCN.org).8–12 Other epidemiologic risk factors associated with cervical cancer are a history of smoking, parity, contraceptive use, early age at onset of coitus, larger number...

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.

Endometrial carcinoma is a malignant epithelial tumor that forms in the inner lining, or endometrium, of the uterus. Endometrial carcinoma is the most common gynecologic malignancy. Approximately two-thirds of endometrial carcinoma cases are diagnosed with disease confined to the uterus. The complete NCCN Guidelines for Uterine Neoplasms provide recommendations for the diagnosis, evaluation, and treatment of endometrial cancer and uterine sarcoma. This manuscript discusses guiding principles for the diagnosis, staging, and treatment of early-stage endometrial carcinoma as well as evidence for these recommendations.
