Which indicates a patient diagnosed at an outside facility but receives part of treatment at your facility?

The scenario described is consistent with class of case 21, which is designated for patients who are diagnosed at a facility other than the reporting facility but receive some treatment at the reporting facility. This classification permits the recording of data for patients whose initial diagnosis may occur elsewhere, acknowledging the treatment history that takes place at the reporting location.

Data collection in oncology is crucial, and it is important for facilities to accurately categorize patients based on their treatment trajectory. Class of case 21 helps ensure that the data collected reflects the patient's comprehensive treatment journey, even when they start their care away from the reporting center. This is vital for cancer registries, as it contributes to a more holistic understanding of patient care and outcomes.

The other options do not accurately reflect this classification. For instance, the notion of it being strictly analytic but not reportable does not align with the treatment nature; the case does qualify as analytic because of the treatment received, and its reportability is essential for tracking treatment pathways in cancer care. Similarly, indicating it does not qualify as analytic fails to recognize the treatment aspect that is fundamental in determining the case class. Class of case 10, which deals with patients diagnosed and treated at the same facility, does not apply here since the diagnosis occurred at an
