THIS INFO CAN BE DERIVED AT QUERY TIME (OMOP)

Preoperative: Refers to radiotherapy given before surgery.
Preoperative Concomitant to Systemic Treatment: Radiotherapy administered before surgery, alongside systemic treatments (like chemotherapy).
Postoperative: Radiotherapy given after surgery.
Postoperative Concomitant to Systemic Treatment: Radiotherapy given after surgery along with systemic treatments.
Definitive: Radiotherapy used as the primary treatment without planned surgery.
Definitive Concomitant to Systemic Treatment: Radiotherapy used as the main treatment alongside systemic therapy with curative intent.

We need to check it also at query time. So we are deriving the information at query time and we will also perform quality checks.

Postoperative: Radiotherapy given after surgery.
Postoperative Concomitant to Systemic Treatment: Radiotherapy given after surgery along with systemic treatments.
Definitive: Radiotherapy used as the primary treatment without planned surgery.
Definitive Concomitant to Systemic Treatment: Radiotherapy used as the main treatment alongside systemic therapy with curative intent.

Preoperative: Refers to radiotherapy given before surgery.
Preoperative Concomitant to Systemic Treatment: Radiotherapy administered before surgery, alongside systemic treatments (like chemotherapy).
Postoperative: Radiotherapy given after surgery.
Postoperative Concomitant to Systemic Treatment: Radiotherapy given after surgery along with systemic treatments.
Definitive: Radiotherapy used as the primary treatment without planned surgery.
Definitive Concomitant to Systemic Treatment: Radiotherapy used as the main treatment alongside systemic therapy with curative intent.

We need to check it also at query time. So we are deriving the information at query time and we will also perform quality checks. Additionally, do them at normalized table in possible cases."/>
