A population-based study of young-onset colorectal cancer patients: Effect of knowledge gaps among patients and providers on stage at diagnosis and quality of life.
4095 Background: Colorectal cancer (CRC) is one of the leading cause of cancer-related death in the US. Despite a decrease in overall incidence and mortality, there has been an alarming increase in CRC diagnosis among young adults (20-49 years old) and causes remain unknown. To explore the unique challenges and unmet needs of the young-adult patients many still establishing their life-long goals, the Colorectal Cancer Alliance launched a comprehensive survey for young-onset CRC patients and survivors via social media to track the self-reported pre-diagnosis awareness, path to diagnosis, and post-diagnosis quality of life experiences of this often overlooked group. Methods: A cross-sectional study, conducted in the form of an online survey, was launched via multiple channels of social media. The questionnaire was based on established instruments including PROMIS, EORTC-QOL-30, and EORTC-CR-29 and EORTC-SHC-22. Results: The survey was completed by 885 patients and survivors. The median age at diagnosis was 42 +/-7, significantly lower than the recommended screening age. Only 6% of respondents were diagnosed with Lynch syndrome although 29% reported some family history. Most respondents (63%) indicated they were not aware that CRC can affect people younger than 50, which may explain why the majority of patients waited more than 3 months and 23% waited over 12 months after noticing their symptoms to visit their doctor. The majority, 75%, of all patients visited 2+ doctors and 11% of those patients visited 10+ doctors before their doctor suspected colorectal cancer. A significant number of patients felt their doctors were dismissive of their symptoms. 77% of patients were diagnosed with advanced disease and were subjected to aggressive therapies that substantially affected their quality of life including neuropathy, anxiety, clinical depression, sexual morbidity, unemployment, and financial toxicity. Many young patients indicated that their doctors did not inform them about fertility preservation. Conclusions: Our survey indicates that medical professionals and young adults need to be aware of the increasing incidence of young-onset CRC, and the importance of timely screening when signs and symptoms are present, regardless of age.
