Background: Colorectal cancer is the second most common cancer in Portugal, which imposes an economic
burden in the restricted health care budget. The aim of this study was to estimate the effects of age, stage, gender, Eastern Cooperative Oncology Group performance status, Charlson Comorbidity Index and category of health care activity on the average colorectal cancer treatment costs based on hospital records before COVID19 pandemic.
Methods: The average monthly costs were estimated in three phases: initial, monitoring and final based on the costs of the patient’s hospital activities. The Kruskal Wallis test was applied to identify treatment costs differences within groups.
Results: The study population included 3020 patients diagnosed with colorectal cancer. Hospitalization, younger patients and higher stages were the main contributors for colorectal cancer costs. Stage IV presented a distinctive cost profile. Significant cost differences were found between age groups and stage in all phases. In the first 24 months after diagnosis, treating a colorectal cancer patient in stage I, II, III and IV, cost in average, 5590, 9180, 13300 and 28450 euros, respectively. Patients with Charlson Comorbidity Index score 0 were more expensive than patients with higher scores.
Conclusion: Our findings illustrate the value of costs studies based on national databases. This study showed the impact of several variables in the costs of colorectal cancer treatment, before COVID 19 pandemic, which may be used to improve the budget distribution of the Portuguese health care system.
