Results

In Japanese lung cancer patients' preference, OS was the most important, followed by diarrhea, nausea, rash, bone marrow suppression, PFS, fatigue, interstitial lung disease, frequency of administration, and duration of administration. The preferences were influenced by demographic characteristics and disease background. Interestingly, the experience of cancer drug therapies and adverse events had a substantial impact on the hypothetical drug preferences.

Baseline Characteristics

Of the total 200 respondents, 191 were included in the subsequent analysis, excluding the nine unreliable respondents who chose the same option for all questions. The proportion of males was 82.7% (158/191), which was considerably higher than in previous studies. The mean age was 63.3 years, similar to that reported in previous studies. Most of the patients were in the early lung cancer stage, with 82 patients (42.9%) in Stage I.

Participant flow

An anonymous web-based questionnaire with a reward was administered from November 25, 2019, to November 27, 2019. Out of the 448 lung cancer patients in the panel held by Rakuten Insight, Inc., 200 people were enrolled in our study.

Prospective participants were informed that they needed to be lung cancer patients to participate in the study. Lung cancer diagnosis was based on the participant's self-report, and no medical diagnosis was made to confirm the condition.

Outcome measures

The relative importance of patient preferences for each attribute as the main effects estimated by the conditional logit model is below. An increase in OS from 10 to 20 months was the most important attribute, followed by an increase in OS from 10 to 15 months and an increase in the occurrence of diarrhea (from 50 to 100%), nausea (from 10 to 50%), rash (from 10 to 80%), and BMS (from 0 to 20%). An increase in PFS from 4 to 9 months was the least important benefit attribute, similar to an increase in fatigue (from 10 to 30%), ILD (from 0 to 5%), and frequency and duration of administration.
