What this trial studies

This observational study aims to create a prospective multicenter international registry of adult patients with active cancer who are experiencing atrial fibrillation. It will track the occurrence of major cardiovascular events over a one-year follow-up period. The study focuses on understanding the implications of atrial fibrillation in the context of cancer treatment and its potential complications. By gathering data from multiple centers, the study seeks to fill gaps in knowledge regarding this common complication in cancer patients.

Who should consider this trial

Good fit: Ideal candidates include adult patients with active cancer diagnosed within the last six months who have experienced at least one episode of atrial fibrillation.

Not a fit: Patients receiving palliative care or those with a history of long-standing persistent or permanent atrial fibrillation prior to cancer diagnosis may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the management and treatment strategies for cancer patients experiencing atrial fibrillation.

How similar studies have performed: While the specific approach of this study is novel, there is a growing body of literature addressing atrial fibrillation in cancer patients, indicating potential for meaningful insights.

Eligibility criteria

Inclusion Criteria:

* adult patients
* outpatients or hospitalized patients
* with a confirmed cancer (other than basal-cell or squamous-cell carcinoma of the skin, primary brain tumor, known intracerebral metastases, or acute leukemia) and an active cancer (defined as cancer that had been diagnosed within the past 6 months or recurrent locally advanced or metastatic cancer, for which anticancer treatment was being given at the time of enrollment or during 6 months before enrollment)
* at least 1 episode of atrial fibrillation (new onset AF occuring after cancer diagnosis or history of paroxysmal of persistant AF prior to cancer diagnosis and an AF recurrence after cancer diagnosis)
* in sinus rhythm at the time of cancer diagnosis

Exclusion Criteria:

* patient with palliative cares or other conditions resulting in short term death (death expected in the month following atrial fibrillation occurrence)
* history of long-standing persistant or permanent AF prior to cancer diagnosis
