Title: Impact of diet and physical activity on the quality of life of colorectal cancer survivors: The DOT study


Introduction: Colorectal cancer (CRC) is the third most common cancer ubiquitously, it is the second leading cause of death worldwide. Surgery, adjuvant chemotherapy or radiotherapy, in all cases, it is not a great journey for CRC patients. Diet and physical activity can be the key for a better life.
Aim of the study: The current study is performed to evaluate the quality of life of CRC survivors in The general and visceral surgery department of the university hospital of Monastir and to identify any probable correlation with diet and physical activity.
Methods: This is a cross sectional study among patients that have been diagnosed with colorectal cancer from January 2014 and January 2021 and who are currently disease-free, were invited to answer a comprehensive package of questionnaires: EORTC-C30 , IPAQ, MDSS.
Results: Among 213 patients, only 57 patients were enrolled in this study, 42.1% female and 57.9% male, ages ranged from 27 to 88 years (M= 64.25 SD= 13.5). The majority were at cancer-stage 2 (45.6%) and 3 (42.1%). Half of the sample (54.4%) went through chemotherapy sessions.
The mean overall quality of life was 78,7 (ranging between 35,71 and 100) abreasting younger males. This number almost goes along with German and French results. The overall QoL in CRC survivors approaches population baseline levels of QoL over time. In the deeper core of quality of life, the functional scale was deteriorated with a median at 46.93 even though the scores ranged from 25 to 95. As for symptom scales, our CRC survivors had average scores stretching between higher fatigue perception (with 41.52) along with insomnia and conversely stubbier digestive symptoms.
Both diet and physical activity has shown spectacular superiority in the overall quality of life of colorectal cancer survivors, especially for physical activity that recorded a statistically significant supremacy (p=0.043).
Conclusion: While we are cautious in making any recommendations based on these findings, this relationship should be explored in future interventional studies. The DOT study refers to the Dream of Tunisians in fitter survival. In the hope that this dream may come true.
