Perception of cancer in patients diagnosed with the most common gastrointestinal cancers

BACKGROUND: Gastrointestinal cancers, including colorectal cancer, stomach cancer and pancreatic cancer are among the most common cancers in Poland. Cancer patients usually assess their quality of life much worse than the general population, while negative emotions associated with the illness may affect the results of treatment. METHODS: The study involved 378 patients with colorectal cancer, stomach cancer and pancreatic cancer, treated as outpatients at the Oncology Center - Maria Skłodowska-Curie Institute in Warsaw in 2013-2018. Standardized tools were used in the study: the Beliefs about Pain Control Questionnaire (BPCQ), the Pain Coping Strategies Questionnaire (CSQ), Approval Illness Scale (AIS), Mental Adjustment to Cancer (MiniMAC). The main goal of the study was to assess pain control, pain management strategies, illness acceptance and adaptation to cancer in patients with the most common gastrointestinal cancers. RESULTS: Patients with gastrointestinal cancers ascribe the greatest role in controlling pain to internal factors (M = 16.84, SE = .34), and the highest score in this area was obtained by patients with colorectal cancer (M = 17.33, SE = .35). The most frequently chosen strategy is declaring coping (M = 20.95, SE = .57), although patients with pancreatic cancer obtained a high score also in the area of catastrophizing (M = 17.99, SE = 1.14). The average value of illness acceptance for patients with gastrointestinal cancers was M = 25.00 (SE = .50) and it was the lowest in the group of patients diagnosed with pancreatic cancer (M = 23.41, SE = 1.16), and the highest in a group of people with colorectal cancer (M = 27.76, SE = .51). Patients with gastrointestinal cancers obtained the highest values of the MiniMAC test in the area of the fighting spirit (M = 21.30, SE = .25), characteristic mainly for patients with colorectal cancer. Patients with pancreatic cancer were characterized by high anxiety and helplessness/hopelessness. CONCLUSIONS: Patients with gastrointestinal cancers use different methods of pain control and pain coping strategies, with active behaviors being preferred by patients with colorectal cancer and destructive - by patients with pancreatic cancer. The majority of socio-economic variables, as well as the treatment method, affect the patients' behaviors.
