Systemic therapy procedure date

The date on which a systemic therapy procedure was performed.

A systemic therapy procedure is a medical, surgical or radiation procedure that has an effect on the hormonal or immunologic balance of the patient, and refers to haematologic transplant and endocrine procedures.

Haematologic transplants are bone marrow or stem cell transplants performed to protect patients from myelosuppression or bone marrow ablation associated with the administration of high-dose chemotherapy or radiotherapy. Endocrine therapy is cancer therapy that achieves its antitumour effect through the use of radiation or surgical procedures that suppress the naturally occurring hormonal activity of the patient (when the cancer occurs at another site) and, therefore, alter or affect the long-term control of the cancer's growth.
