Purpose In lung cancer, the preservation of well-being is warranted given the limited prognosis. Chemotherapy may negatively influence health-related quality of life (HRQoL) due to adverse events. However, patients’ judgement about this negative impact is not well understood. We examined the relationship between expectations, feelings about side effects, and satisfaction with therapy and (HR)QoL in advanced-stage thoracic cancer and investigated which of these factors has the highest impact on (HR)QoL.

Methods Sixty-nine patients completed the Cancer Therapy Satisfaction Questionnaire (CTSQ), the World Health Organization Quality of Life-BREF (WHOQOL-BREF), and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). Multiple regression analyses were performed to investigate the relation of the CTSQ domains (i.e., expectations of therapy, feelings about side effects, satisfaction with therapy) with (HR)QoL and simple regression analyses to identify the factors of the CTSQ domain that was most often associated with (HR)QoL.

Results Feelings about side effects were associated with the (HR)QoL domain/scale scores (i.e., WHOQOL-BREF domains: β = 0.36 to 0.58; EORTC QLQ-C30 scales: β = 0.33 to 0.61) except social relationships of the WHOQOL-BREF. Low-grade adverse events were related to feelings about side effects (β = − 0.326; P = 0.007).

Conclusions Patients experiencing negative feelings about side effects have worse (HR)QoL. Additional care should be provided to prevent low-grade adverse events.
