Quality of life in colorectal cancer patients: an Izmir Oncology Group (IZOG) study.

PURPOSE: To investigate the variables of quality of life (QoL) among Turkish patients with colorectal cancer (CRC). METHODS: In this prospective study we investigated the QoL of Turkish CRC patients. Two hundred and twenty two patients with CRC were included. The sociodemographic form and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) were used. RESULTS: The study group consisted of 142 males (64%) and 80 females (36%). The mean patient age was 55.68±11.387 years. The majority of the patients (36.9%) had local disease while advanced-stage disease and locally advanced stage disease had 32.2% and 28.8% of the patients; respectively. The mean QoL score was moderate (62.81± 27.0). The most common complaints were fatigue, economic difficulties and constipation. Gender, education level and disease stage were associated with QoL. Physical, role and social functioning were more adversely affected in female patients. Compared to women, men had significantly more favorable global QoL (p=0.044). Some functional scales were worse in advanced disease compared to other stages.These outcomes were statistically significant in the functional scales of global health (p=0.007), physical (p=0.03), cognitive (p=0.01) and emotional function (p=0.007). Patients with advanced disease had worse outcomes in some symptoms (nausea, vomiting, dyspnea, loss of appetite and financial distress). CONCLUSIONS: Female gender and advanced disease were strongly associated with poorer QoL among Turkish CRC patients.
