The purpose of the study was to assess the impact of postchemotherapy nausea and vomiting (PCNV) after moderately emetogenic chemotherapy on health-related quality of life (HRQOL) in patients with cancer being treated in a routine clinical practice setting. The European Organization for Research and Treatment in Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30) was administered on day 2 and day 6 following moderately emetogenic chemotherapy to 119 patients with a variety of cancers. Patients kept daily diaries to record the occurrence and severity of nausea and vomiting. The QLQ-C30 questions were modified, for this study only, to assess the impact of nausea and vomiting on HRQOL in patients who experienced nausea and/or vomiting during the six days following chemotherapy. Those patients who experienced either nausea or vomiting experienced a decrease in HRQOL from prechemotherapy levels on six functioning and five symptom scales at day 2, and on four functioning and four symptom scales on day 6. Comparison of mean scores between the unmodified QLQ-30 and the nausea and vomiting versions demonstrated that the HRQOL rating attributed to nausea and vomiting accounted for much, but not all, of the deterioration in HRQOL scores in patients who experienced these symptoms. It can be concluded that patients who experience PCNV experience a significant negative impact on their HRQOL and that this impact can be attributed in large part to their experience of nausea and vomiting. However, since not all of the deterioration is attributable to these symptoms, other reasons for some of the decrease in HRQOL must also be identified in future studies.
