Living cancer patients with histologically confirmed rare molecular alterations in their tumours, such as in ALK, EGFR, ROS1, BRAF, and KRAS G12C from participating sites/cancer centres across Canada.

Deceased cancer patients who had histologically confirmed rare molecular alterations in their tumours, such as in ALK, EGFR, ROS1, BRAF, and KRAS G12C from participating sites/cancer centres across Canada.

All cancer patients without rare molecular alterations in their tumours. This group will be established in order to determine baseline characteristics and outcomes, including treatment outcomes, of more standard treatments such as systemic chemotherapy or immunotherapy.

Observing cancer patients who have received or are currently receiving tyrosine kinase inhibitors (TKIs) or other molecularly targeted therapies for their cancer treatment.

Cancer treatment with tyrosine kinase inhibitors (TKIs) or other molecularly targeted therapeutic agents.

Prospectively enrolled participants will be provided with survey packets comprised of different PRO instruments at the initial/baseline visit, at 3 month follow up intervals and at the time when treatment/therapy is changed.

This study will collect data on Canadian cancer patients that have uncommon/rare changes in their tumours, such as alterations/rearrangements in the genetic material inside cells - known as deoxyribonucleic acid, or DNA, which acts as a map and gives directions to the cells on how to make other substances the body needs - because some of these changes have been found to respond to different drugs that help to stop the cancer. These rare changes occur in genes such as but not limited to ALK, EGFR, ROS1, BRAF, and NTRK which have targeted drugs in a family known as tyrosine kinase inhibitors (TKIs), and KRAS G12C mutation, which now has a targeted inhibitor drug therapy for patients with non small cell lung cancer (NSCLC). The goals for the study are to compare the natural history of such cancers and the treatment outcomes, including toxicities and patient-reported outcomes, for the different therapies.

Molecular heterogeneity in cancer tumours make it a complex disease to manage and treat. However, there have been significant advancements made in the detection of molecular alterations and we are able to now define distinct disease subtypes which permit targeted selection of therapies, thus optimizing treatment responses for patients and improving their survival.

With CARMA-BROS we will address the objectives that follow.

Primary Objectives:

1. To create a cohort of patients through which to better understand the natural history of disease in Canadian cancer patients with tumours that have been molecularly subtyped and identified to have rare molecular alterations.
2. To compare the natural history, stage distribution, treatment outcomes such as treatment effectiveness (composite of disease progression or death) and treatment toxicities across different patients with different molecular alterations, receiving different lines and types of therapy.

   Secondary Objectives:
3. To determine the incidence, time to development, prevalence, and outcomes of patients with specific patterns of spread, such as brain metastases compared to those without, by different therapies and by molecular alterations.
4. To better understand real-world treatment patterns of rare molecular alterations in the Canadian context, across geographic or other factors, and how treatment patterns evolve over time and as new therapies become available, how patients are investigated and how targeted and other biomarkers are used as part of clinical practice in these patients.
5. To assess quality of life in patients with rare molecular alterations across different stages, lines and types of therapy.
6. To perform exploratory health economic evaluations focused on the costs and benefits of managing patients with rare molecular alterations.
7. To perform biomarker analyses, where appropriate, to improve our understanding of these rare molecular alterations.

Composite of disease progression or death

Confirmed through imaging (MRI, CT) or determined through treatment indication(s), for example, brain radiation therapy (surrogate for presence of brain metastasis)

Prospectively enrolled participants will complete the following health related quality of life surveys: EORTC QLQ-C30 (core) and EORTC QLQ-LC13 (disease specific module)

Prospectively enrolled participants will complete the health related quality of life survey: EQ-5D-5L.

Prospectively enrolled participants will complete the "Work Productivity and Activity Impairment Questionnaire: General Health" (WPAI:GH) and other economic impact questions that capture indirect costs incurred as a result of their disease.
