Summary
Brief summary (as posted)
This is a multi-site clinical study enrolling 2000 newly diagnosed patients with breast, colorectal, melanoma, non-Hodgkin lymphoma, or non-small cell lung cancer, who are planning to receive one or more systemic cancer directed therapies with chemotherapy and/or (immune checkpoint inhibitors) ICIs.

- description
- Will use the National Cancer Institute Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events to measure cancer-related symptoms. Will examine the longitudinal relationship between cannabis and/or cannabinoid use and the likelihood of exhibiting individual symptoms using three-level GLMMs to account for the nested data. The investigators will model continuous measures (e.g., symptom severity) using a linear generalized linear mixed-effects models (GLMM) and the prevalence of symptoms or moderate to severe symptoms using a logistic GLMM. Cannabis and/or cannabinoid use at each monthly assessment will be included as a time-varying covariate and an interaction with time will be included to assess its impact on symptoms over time. Analyses will consider dichotomous definitions of use (yes/no past month), frequency of use (# days in the past month) as well as mode of administration, dose/potency, and cannabinoid type.
