Quantitative Preferences for Lung Cancer Treatment from the Patients' Perspective: A Systematic Review.

BACKGROUND

Regulatory agencies as well as private organizations pursue programs that advocate patient centricity and emphasize the importance of dialog with patients. Various methods are applied to elicit the preferences of patients regarding the aspects of treatment they lend more importance to. Decisions on treatment choices are critical to patients with lung cancer because of their poor prognosis and the serious trade-off between safety and efficacy in traditional cytotoxic chemotherapy.

METHODS

We conducted a systematic literature review of quantitative patient preference studies of patients with lung cancer. Our exhaustive search of MEDLINE, CINAHL, EMBASE, PLOS, and SpringerLink identified 15 relevant studies published from January 2000 to April 2020 that enabled us to assess the relative importance of treatment attributes according to lung cancer patients' perspective.

RESULTS

The literature review revealed that patients with lung cancer tend to place a higher weight on efficacy and quality of life (QoL) attributes than on other attributes. Overall survival was found to be the most important among the efficacy attributes. The consequences of adverse events seemed less important than the possible efficacy from therapies. The clinical utility of treatment, such as the route of administration, was generally not considered important. It remains inconclusive whether sociodemographic factors and/or medical history affect the relative importance of a patient's preference.

CONCLUSION

Our systematic review clarified that patients generally prefer a better efficacy profile to a better safety profile, which underscores the importance of improved benefits in anti-lung cancer drug development.
