Prospective Evaluation of the Influence of Chemoradiotherapy and Stoma on Functional and Symptomatic Outcomes in...

Rectal cancer is a major cause of morbidity and mortality worldwide, and although current therapeutic protocols have improved survival, treatment-related toxicities may significantly affect patients' daily functioning and emotional well-being. This study aimed to prospectively assess the impact of radiotherapy with concurrent capecitabine on functional and symptomatic outcomes in patients with rectal cancer, with a particular focus on the presence of a stoma and treatment strategy.

From 165 patients initially assessed, 64 were included in this study after applying eligibility criteria. All received pelvic radiotherapy (50.4 Gy in 28 fractions); 62.5% also received CAPOX chemotherapy. The quality of life was assessed using EORTC QLQ-C30 and QLQ-CR29 questionnaires administered at three time points: before treatment, mid-treatment (day 15), and post-treatment.

A statistically significant deterioration was observed in physical, emotional, social, and role functioning over the course of treatment, along with an increase in symptom scores for fatigue, pain, gastrointestinal, and urinary complaints. The presence of a stoma was significantly associated with worse gastrointestinal symptoms and emotional functioning. No significant differences were noted between patients with or without chemotherapy. Despite symptom worsening, global quality-of-life scores remained relatively stable.

These findings highlight the complex interplay between treatment toxicity and patient adaptation. The presence of a stoma and other clinical or demographic factors significantly influence patients' experience during therapy. Integrating routine assessment of functional and symptomatic burden into clinical practice could support individualized interventions aimed at maintaining daily functioning and psychological resilience during treatment.
