What is the date of first contact for a patient who had multiple hospital visits, including a diagnosis of adenocarcinoma?

The date of first contact for a patient is typically determined by the earliest documented interaction with the healthcare system that is related to their cancer diagnosis. In the context of the scenario describing multiple hospital visits and a diagnosis of adenocarcinoma, this date represents the first instance where the patient was identified in the cancer registry or treatment protocol.

In this case, if "02/03/2024" is indicated as the date of first contact, it suggests that this is the earliest date when the patient's condition was formally recorded or assessed. This date is crucial as it establishes the timing for various treatment protocols and follow-up actions. A precise understanding of this date is significant for tracking outcomes, treatment efficacy, and for compliance with oncology data reporting standards.

Identifying the correct date is essential for accurate patient records and helps ensure that appropriate steps are taken in the management of the patient's cancer journey.
