Carcinoid tumors increasing in young adults at a faster clip than adencarcinomas

Reuters Health - 14/12/2020 - A new analysis confirms that adenocarcinomas are steadily increasing in young patients, but carcinoid tumors, another type of CRC, are increasing as well, and at a faster rate. The researchers assessed early-onset CRC incident rates and changes in incident rates over time, stratified by histologic subtype (primarily adenocarcinoma and carcinoid tumors), using SEER data from 2000 to 2016 for 119,624 patients with CRC. "This is the first study to analyze early-onset colorectal cancer by specific histologic subtype," Dr. Jordan Karlitz, from Tulane University, New Orleans, told Reuters Health by email. They found that 4% to 20% of CRCs were carcincoid tumors, which are typically indolent with a better prognosis, as opposed to adenocarcinoma, the CRC subtype that is the primary focus of screening. Incidence rates of carcinoid tumors "increased at a steeper pace than those of adenocarcinoma in all age groups, thus accounting fo...
