Conference Paper

4 Background: The growing number of colorectal cancer (CRC) survivors often have multiple chronic conditions. Comparing CRC survivors and matched non-cancer controls, our objectives were to determine the odds of CRC survivors being diagnosed with CVD-related chronic conditions and their likelihood of control during the year after CRC diagnosis. Methods: We retrospectively identified patients diagnosed with non-metastatic CRC in the Veterans Affairs (VA) healthcare system from fiscal years 2009-2012 and matched each with up to 3 non-cancer control patients. We used logistic regression to assess differences in the likelihood of being diagnosed with CVD-related chronic conditions and control between CRC survivors and non-cancer controls. Results: We identified 9,758 CRC patients and matched them to 29,066 non-cancer controls. At baseline, 69.4% of CRC survivors and their matched controls were diagnosed with hypertension, 52.4% with hyperlipidemia, and 36.7% with diabetes. Compared to matched non-cancer controls, CRC survivors had 57% higher odds of being diagnosed with hypertension (OR = 1.57, 95% CI = 1.49-1.64) and 12% higher odds of poor blood pressure control (OR = 1.12, 95% CI 1.06-1.18) in the subsequent year. Compared to matched non-cancer control patients, CRC survivors had half the odds of being diagnosed with hyperlipidemia (OR = 0.50, 95% CI = 0.48-0.52) and higher odds of LDL control (OR 1.14, 95% CI 1.06-1.23). There were no significant differences between groups for diabetes diagnoses or control. Conclusions: Compared to non-cancer controls, CRC survivors have: 1) greater likelihood of being diagnosed with hypertension and worse blood pressure control in the year following diagnosis; 2) lower likelihood of being diagnosed with hyperlipidemia or LDL control; and 3) comparable diabetes diagnoses and control. There may be a need for hypertension control interventions targeting cancer survivors.
