Abstract

Aim:

To assess local experience in Saudi Arabia of the effectiveness and tolerability of selective internal radiation therapy (SIRT) in patients with liver tumours.

Materials and methods:

In a retrospective study, patients with unresectable liver tumours treated with yttrium-90-labelled resin microspheres (SIR-Spheres®, Sirtex, Australia) at the King Fahad Specialist Hospital Dammam (KFSHD) were followed up for at least 12 months, or until death. Data were extracted from medical records. The primary outcome measure was overall survival (OS). Tumour response was recorded using the modified Response Evaluation Criteria in Solid Tumors (mRECIST): tumour control (TC) was defined as the proportion of patients with stable disease (SD), partial response (PR) and complete response (CR).

Results:

A total of 30 patients (21 males, 9 females) with hepatocellular carcinoma (76⋅7%), metastatic colorectal cancer (13⋅3%), cholangiocarcinoma (6⋅7%) or carcinoid tumour (3⋅3%) were evaluated. Mean OS was 16⋅98 months. Eighty-five percent of patients showed TC, 35% had SD, 15% a PR and 35% a CR. No severe complications were observed. Four deaths were considered unrelated to treatment.

Findings:

In this cohort, SIRT showed similar efficacy to that in other studies, with an acceptable tolerability profile. SIRT appears a feasible procedure for liver tumour treatment in the KFSHD.
