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.
