Hepatobiliary cancers are both common and highly lethal worldwide. However, in the United States, the incidence of hepatobiliary cancer is relatively low, with approximately 23,700 patients newly diagnosed each year. Gallbladder cancer is the most common of the hepatobiliary malignancies, accounting for approximately 30% of newly diagnosed cases in the United States. Along with summaries of the NCCN guidelines for the 4 subtypes of hepatobiliary cancer, this article includes a brief discussion of the epidemiology, pathology, etiology, staging, diagnosis, and treatment of each subtype.

Hepatobiliary cancers are common worldwide and highly lethal. Hepatocellular carcinoma is the most common hepatobiliary malignancy and the seventh most common cancer worldwide. Gallbladder cancer is the most common biliary tract malignancy, accounting for approximately 5000 newly diagnosed cases in the United States. Cholangiocarcinomas are diagnosed throughout the biliary tree and are usually classified as intrahepatic or extrahepatic. Intrahepatic cholangiocarcinomas arise from intrahepatic small-duct radicals, whereas extrahepatic cholangiocarcinomas encompass hilar carcinomas (including Klatskin's tumors). These guidelines discuss these subtypes of hepatobiliary cancer and the epidemiology, pathology, etiology, staging, diagnosis, and treatment of each subtype.

Inflammatory breast cancer (IBC) represents the most virulent form of breast cancer, characterized by involvement of the skin and rapid progression of the disease. Management involves careful coordination of multidisciplinary modalities, including imaging, systemic chemotherapy, surgery, and radiation therapy. The use of neoadjuvant chemotherapy has contributed significantly to improvement in overall survival since the first descriptions of this entity, and has made the role of locoregional therapy, including surgery and radiation, critical to continued improvements in this disease. This article examines the unique epidemiology and pathology of IBC, and reviews the various treatment modalities, noting the significance of a multimodality approach and delineating each of the specific components. Moreover, the current research in IBC is briefly described, which experts hope will further improve systemic therapies.

Lymphatic mapping and sentinel node identification are rapidly becoming the standard of care in managing many malignancies. These procedures have allowed focused evaluation of relevant regional lymphatics, which has led not only to improved precision of nodal pathology, but also to treatment triage and the potential for reduced postoperative morbidity. Given its clinical potential, new cancer primary sites are being evaluated, including those of the female genital tract. Of these, carcinoma of the vulva seems the most apposite; however, it is a rare malignancy and therefore large randomized treatment trials based on sentinel node triage are difficult to perform. Cancers of the uterus–cervix and corpus are more common. Because the physiologic lymphatic drainage from this organ is ambiguous, principle lymphatic basins are located in many different anatomic locales, making sentinel node identification precarious, yet highly relevant and informative. Current experience in carcinoma of the cervix suggests the concept is feasible. A consensus in corpus cancer has not been reached, although both sites are of keen interest with the increasing use of laparoscopy in surgical management. Prospective multi-institutional validation studies are underway.
