e18340 Background: Online crowdfunding, where individuals create campaigns to solicit donations, has grown as an avenue to combat the financial toxicities of cancer. The online platform GoFundMe hosts more than 80% of the global market for crowdfunding and has raised over US $5 billion from more than 50 million donors. While medical expenses are the leading cause of crowdfunding campaigns, limited research is available on the use of crowdfunding for cancer costs. Further, no studies have evaluated the use of crowdfunding for patients with lung cancer. Methods: In January 2019, we reviewed the first 200 consecutive campaigns that resulted for “lung cancer” on GoFundMe. Campaigns were included for analysis if their description stated funds were to be used for medical costs for a patient with lung cancer in the United States. Standardized data was collected from each campaign. Descriptive statistics were used to aggregate results. Multivariable linear regression analysis were performed to examine predictors of funds raised, adjusting for campaign duration. Results: The 157 included campaigns raised a total of US $1.2 million (mean $8,364) from 11,919 donors (median 53). Compared to a similar 2018 study, our study showed lung cancer campaigns raised less than breast cancer (mean $16,026) but more than prostate cancer (mean $1,449) campaigns. Nine campaigns that were seeking funds for alternative treatment raised a total of $119,660 (mean $13,296). Narratives of financial need that were significantly associated with greater funds raised were family financial need (+$7,416), medical costs not covered by insurance (+$7,369), and the campaign stating the patient was a never-smoker (+$8,162) (all P values < 0.05). Conclusions: Lung cancer has received less research funding relative to other cancer types and our study suggests a similar disparity with crowdfunding for medical costs. The “blame-the-victim” attitude that contributes to this funding disparity also exists within lung cancer crowdfunding as evidenced by the significantly greater amount of funds raised for campaigns that explicitly stated the patient was a non-smoker. Efforts to study crowdfunding for cancer costs should address the ethical implications of exacerbating funding disparities and funding for alternative treatments.
