Quality of life and somatic physical function of patients with colorectal cancer who underwent oxaliplatin-based systemic chemotherapy: a prospective study.

Abstract

Introduction: This study aimed to study the potential effects of oxaliplatin-based chemotherapy on cardiorespiratory fitness, handgrip strength (HGS), body composition, and quality of life (QoL) of stages III-IV colorectal cancer (CRC) patients before the first cycle (T0) and after the last cycle of systemic adjuvant/neoadjuvant chemotherapy (T1).

Methods: Cardiorespiratory fitness, HGS, body composition, and QoL were evaluated with the six-minute walk test (6MWT), hydraulic hand dynamometer, body composition analyzer, and Functional Assessment of Cancer Therapy-Colon (FACT-C) questionnaire in both T0 and T1, respectively.

Results: Twenty-eight CRC patients were included in this study. The total walked distance (TWD) was found to be decreased from T0 to T1 (499.72 m vs. 488.56 m); however, this change was not significant (z = -.706, p = 0.48). Type of chemotherapy whether adjuvant or neoadjuvant also showed no significant effect on TWD (z = -.1.372, p = .17 vs z = -1.180, p = .238, respectively). The QoL was significantly decreased (T0 = 118.35 vs T1 = 110.77, t = 2.176,p = 0.05). The TWD was significantly correlated with the physical well-being (PWB) subscale of FACT-C (r = .64, p = 0.001) as well as with HGS (r = .46, p = .018) in T0. After controlling for age, type of chemotherapy, and type of regimen, the HGS did not show a significant difference from T0 to T1 (F(1,23) = 1.557, p = .22, ηp² = .06). However, the effect of time x gender showed significant difference from T0 to T1 (F(1,23) = 4.906, p = .037, ηp² = .17).

Conclusion: This study showed the decreased QoL and physical well-being of CRC patients who underwent oxaliplatin-based treatment. In addition, the gender effect of decreased HGS should be considered further when planning an oncological rehabilitation program.
