Aim: Studies have shown effects of surgery, radiation and chemotherapy on quality of life in cases of gynaecological cancer. Very few studies are available examining the quality of life of individuals in Turkey who have been diagnosed with gynaecological cancer and undergoing treatment. Method: This study was performed to evaluate the quality of life of such patients using the EORTC-QLQ-C30 Quality of Life Index. Chi-square Yates, Mann-Whitney-U tests and variance analysis used for statistical analizing. Results: The EORTC-QLQ-C30 Quality of Life Index mean points for "general well-being and quality of life" of the patients were found to be $60.5{pm}25.0$. In the sub-groups of the Quality of Life Index determined fatigue ($60.1{pm}24.8$), economic difficulties ($46.9{pm}33.3$), pain and loss of appetite ($42.9{pm}27.8$; $42.9{pm}34.0$) and insomnia ($40.1{pm}34.0$) were the symptoms most reported to have a negative effect on quality of life. Statistical significance was noted for marital status and income status (p<0.05) but not educational level. Conclusion:Determination of quality of life of women with a diagnosis of gynaecological oncological disease who are undergoing chemotherapy enables provision of a more comprehensive and higher quality of care.
