American College of Surgeons Cancer Program Annual Report from 2021 Participant User File.

The National Cancer Database (NCDB) collects data from approximately 1,500 Commission on Cancer (CoC) facilities and represent 73.7% of newly diagnosed cancers nationwide. The American College of Surgeons Cancer Program developed it first annual report from the NCDB 2021 participant user file reporting new observations and recent trends of cancer diagnoses, patient demographics, and treatments as well as an in-depth report on treatment and outcomes in breast, pancreas, and colon cancers. Of the 1,328,131 cancers diagnosed in 2021 at 1,281 reporting CoC hospitals, one-fifth continue to be female breast cancer. In 2021, the NCDB's 5 most common adult cancers were breast, prostate, lung, colon, and melanoma and varied by patient sex. Use of neoadjuvant systemic therapy increased in recent years in pancreas, breast, and urinary bladder cancer, although a slight decrease in pancreas and breast cancer was observed in 2021. Breast cancer has high survival rates, especially in lower-stage disease and estrogen receptor-positive/human epidermal growth factor receptor 2-negative disease. There is increase in neoadjuvant systemic therapy use, especially in human epidermal growth factor receptor 2-positive disease and estrogen receptor-negative disease. Colon cancer presents most commonly as stage III or II with a primary in the cecum or ascending colon in 38.9%. The majority are microsatellite instability stable, Kirsten rat sarcoma viral oncogene homologue normal, and CEA positive. Survival is most dependent on stage but also associated with microsatellite instability stability, abnormal Kirsten rat sarcoma viral oncogene homologue, and positive CEA. Pancreatic cancer presents with stage IV disease in nearly half, although an increase in stage I disease is seen. The most common location is pancreatic head. Survival is relatively low and most dependent on stage.
