Early detection and prompt treatment can make a big difference in improving outcomes for ampullary tumors, which occur around a small opening at the junction of the duodenum, bile duct, and pancreatic duct. Ampullary adenocarcinoma accounts for less than one percent of all gastrointestinal malignancies, but tends to have a higher cure rate than other biliary tract and pancreatic cancers that may occur in the same general area.1-5
Malignant peritoneal mesothelioma (MPeM) is a rare, aggressive cancer that occurs in the lining of the abdomen (peritoneum) in about 600 patients every year in the United States. The new guidelines include an extensive section on the specific pathology tests that can be used to accurately identify MPeM, since it is challenging to diagnose due to its rarity and the fact that symptoms mimic other diseases like ovarian cancer. There is currently no recognized staging system for MPeM to assist with prognosis and treatment.6-8
“It can be hard for people with rare diseases to get the attention they deserve, but at NCCN we are doing all that we can to support people with any type of cancer, along with their loved ones and health care providers,” said Dr. Koh. “The NCCN Guidelines currently cover 97 percent of cancer cases in the U.S., and we’ll keep adding more guidelines.”
Another element in NCCN’s efforts to improve patient care and safety for both rare and common cancers are the NCCN Chemotherapy Order Templates (NCCN Templates®), which recently surpassed 2,000 regimens. These resources provide user-friendly information on chemotherapy, immunotherapy, supportive care agents, monitoring parameters, and safety instructions, based on recommendations in the NCCN Guidelines. They help reduce medication errors and anticipate and manage potential adverse events, while standardizing patient care. Learn more at NCCN.org/ templates.
