Comments
Guide for use:
Systemic therapy procedures 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.
Haematologic transplant or endocrine procedures may be provided to prolong a patient's life by controlling symptoms, to alleviate pain, or make the patient more comfortable.
Each systemic therapy procedure delivered to the patient during the initial treatment for cancer should be recorded. The initial course of treatment includes all treatments administered to the patient from diagnosis and before disease recurrence or progression.
The procedure code for each treatment episode should be entered separately.
Bone marrow transplants should be coded as either autologous (bone marrow originally taken from the patient) or allogeneic (bone marrow donated by a person other than the patient). For cases in which the marrow transplant was syngeneic (transplanted marrow from an identical twin), the item is coded as allogeneic.
Stem cell harvests involve the collection of immature blood cells from the patient and the reintroduction by transfusion of the harvested cells following chemotherapy or radiation therapy.
Endocrine procedures must be bilateral to qualify as endocrine surgery or endocrine radiation. If only one gland is intact at the start of treatment, surgery and/or radiation to that remaining gland qualifies as endocrine surgery or endocrine radiation.

The collection of specific treatment information is useful to evaluate patterns of care, the effectiveness of different treatment modalities, and treatment by patient outcome.
Note the distinction between the administration of systemic agents or drugs and systemic therapy procedures that affect the hormonal or immunologic balance of the patient.References
