Brief summary

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.

Detailed description

The objective of this study is to examine the association between cannabis and/or cannabinoid use and cancer-related symptoms assessed monthly for one year in adults newly diagnosed with breast, colorectal, melanoma, non-Hodgkin lymphoma, or non-small cell lung cancer who are planning or recently started to receive one or more systemic cancer directed therapies with chemotherapy and/or immune check point inhibitors (ICIs) targeting PD-1, PD-L1 or CTLA-4. Participants complete surveys and have their medical records reviewed on study.

Inclusion criteria

* Adults aged 18 years or older with one of the following newly diagnosed cancers: breast cancer, colorectal cancer, melanoma, non-Hodgkin lymphoma, or non-small cell lung cancer (e.g. adenocarcinoma, squamous cell carcinoma, large cell carcinoma, adenosquamous cell carcinoma, and not otherwise specified). * Planned treatment with systemic chemotherapy (single or multi-agent, includes targeted therapy) and/or immune checkpoint inhibitor therapy (targeting PD-1, PD-L1 or CTLA-4). If unable to engage participant before treatment starts, enrollment is allowed up to the start of Cycle 2 treatment. * Participants must be able to comprehend English or Spanish (for survey completion). * Participants must have a working email address and be must be willing to complete surveys online. This can be completed at home, in the clinic or other location. * Completion of the confidential Self-Reported Screening Survey and receipt of a screening result - eligible for enrollment. * Participant must reside in the United States, officially determined per patient report on Self-reported Screening Survey * In the treating provider's opinion, the participant should have a life expectancy of \>=6 months. Participants in hospice are not eligible. Optional Sub-study (available at select sites only): * Must be willing to participate in both the main study and the sub-study at the Wake Forest University Comprehensive Cancer Center (WF CCC) and Virginia Commonwealth University (VCU). * Must be receiving treatment at the WF CCC and VCU. * Must be diagnosed with non-small cell lung cancer. * Must be planning to receive paclitaxel as part of their chemotherapy in conjunction with Immune Checkpoint Inhibitor (ICIs) PD-1, PD-L1 or CTLA-4.

Exclusion criteria

* Currently enrolled in an interventional supportive treatment trial to manage cancer symptoms. * Participants with known pregnancy. * Participant received systemic therapy treatment for prior cancer(s) including chemotherapy, immunotherapy, targeted therapy, and hormonal therapy. * Participants enrolled in hospice. Optional Substudy (available at select sites only): * Participants with chronic or ongoing steroid or immunomodulatory agents (i.e., prednisone, dexamethasone, etanercept, infliximab, etc.). The use of glucocorticoids as pre-medications for chemotherapy treatment is allowed. * Participants with a history of HIV, hepatitis B or hepatitis C.

Design outcomes

Primary

MeasureTime frameDescription
Cancer-related symptomsBaseline and re-assessed monthly up to 12 months post-enrollmentWill 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.

Secondary

MeasureTime frameDescription
Cannabis and Cannabinoid Use from Cannabis Engagement AssessmentBaseline and re-assessed monthly up to 12 months post-enrollmentCannabis and cannabinoid use will be measured monthly using items from the Cannabis Engagement Assessment (CEA). The CEA contains 30 questions that assess the quantity, frequency of use, and method of consumption for dried cannabis products (excluding edibles), cannabis concentrates, and edible products in the previous 30 days. Two additional sections assess other factors associated with cannabis use and history of use. Estimates of consumption can be calculated from responses, with a lower limit of 0 and no upper limit. Higher values represent higher consumption in that month.
Cannabis and Cannabinoid Use from the International Cannabis Policy Study surveyBaseline and re-assessed monthly up to 12 months post-enrollmentCannabis and cannabinoid use will be measured monthly using items from the International Cannabis Policy Study (ICPS) survey. The ICPS surveys provide a comprehensive assessment of cannabis use, includes detailed patterns of consumption, purchasing, adverse outcomes, as well as attitudes and beliefs towards cannabis. Results from this survey will help quantify amount of cannabis use, if any.
Cannabis and Cannabinoid Perceived Benefits and HarmsBaseline and re-assessed monthly up to 12 months post-enrollmentThe NCI Cannabis Core Measures survey will be used to ask cannabis and cannabinoid users each month whether they think cannabis or cannabinoid use worsened or improved their symptoms. Using the NCI Cannabis Core Measures survey, the investigators will ask cannabis and cannabinoid users each month whether they think cannabis or cannabinoid use worsened or improved their symptoms. The investigators will define this as a nominal outcome where 0=no change; 1=worsened quite a bit or somewhat worsened, and 2=somewhat improved or improved quite a bit.
Cannabis and Cannabinoid Adverse EffectsBaseline and re-assessed monthly up to 12 months post-enrollmentThe Adverse Reactions Scale will be used to ask cannabis and cannabinoid users each month whether they have experienced a checklist of potential adverse reactions. The investigators will participants using cannabis and/or cannabinoids each month whether they have experienced a checklist of potential adverse reactions. These are defined as presence or absence of the adverse effect. The investigators will also consider the frequency of time they experience the effect (% of time they experience the effect when consuming cannabis or cannabinoids) and the severity of the effect (0 = Not at all distressing; 1 = Mildly distressing; 2 = Moderately distressing; 3 = Quite distressing 4 = Severely distressing) as continuous measures.
