Pharmacist Medication Checks for People Receiving Targeted Radionuclide Therapy for Cancer

TRT has historical roots, dating back to the 1950s with the introduction of radioactive iodine-131. It has long been used for the treatment of thyroid cancers, which require hospitalization for 3 to 5 days in a dedicated, isolated, and radioprotected environment.

In recent years, TRT has undergone significant development with the emergence of new isotopes coupled with innovative molecules targeting a wider range of cancers. Lutathera ([177Lu]Lu-DOTATATE) and Pluvicto ([177Lu]Lu-PSMA-617), available since 2021, have revolutionized the management of patients with neuroendocrine tumors and metastatic prostate cancer, respectively. Numerous clinical trials are currently underway or planned, further expanding the field. These cutting-edge treatments are administered intravenously-mostly on an outpatient basis-within nuclear medicine departments under strict radioprotection protocols.

More recently, several healthcare institutions in France have introduced systematic clinical pharmacy activities for all patients treated with TRT, allowing for pharmaceutical validation of patient care. These activities may include:

A medication reconciliation (MR): a comprehensive list of all current and planned medications, gathered from at least three sources (e.g., prescriptions, general practitioner, medical records, and a pharmacist-led interview to gather additional details);

A basic prescription review without medication history collection;

Medication reconciliation at hospital admission or discharge.

These activities, carried out by the radiopharmacist, aim to lead to a pharmaceutical intervention (PI)-a proposal to modify a medical prescription in response to a detected medication-related issue.

This project aims to evaluate the impact of radiopharmacy activities, particularly medication reconciliation and pharmacist-patient interviews, in securing the care pathway for patients undergoing TRT. A key component of this work is the creation of a national collaborative database, in partnership with the French Society of Radiopharmacy (SOFRA). This database will also document the range of clinical radiopharmacy activities implemented across different institutions, their feasibility, the pharmaceutical interventions made, and their contributions to patient monitoring and safety.
