DiscussionRapidArc has an obvious advantage in improving the degree of target coverage, improving organs at risk, sparing healthy tissue, and significantly reducing the treatment time. FDG-PET/CT can increase the agreement between biopsies and delineated tumor volume and has the potential to positively impact the course of treatment. The Comet assay is attractive as a potential clinical test of tumor radiosensitivity. During radiotherapy, accurately defining disease areas is critical to avoid the unnecessary irradiation of normal tissue. Based on FDG-PET/CT and Comet assay, higher doses can be safely delivered to accurate ...

ConclusionsSIRT is a safe and effective therapy for certain patients with unresectable colorectal liver metastases. This case series supports our opinion that selected patients should be offered SIRT in concert with their medical oncologist, concomitant with their chemotherapy. Larger multi-center studies are required to more clearly define the patient groups that will derive most benefit from SIRT.

Abstract Hepatocellular carcinoma (HCC), the predominant form of primary liver cancer, is the second leading cause of cancer‐related deaths across the globe. Only a small percentage of HCC patients (~20%‐30%) are diagnosed at an early stage when first‐line treatment options may be effective. The majority of HCC patients (>70%) are diagnosed with unresectable disease and given a poor overall prognosis. Current treatment guidelines recommend locoregional therapy with transarterial chemoembolisation (TACE) and systemic therapy with sorafenib as first‐line treatment for patients with intermediate and advanced stage ...

Patients with colorectal cancer that has metastasized to the liver derive a significant benefit from selective internal radiation therapy (SIRT) combined with chemotherapy if their primary tumor is a right-sided tumor, but not if it is a left-sided primary tumor.

Sirtex Medical (ASX:SRX) said yesterday that the National Comprehensive Cancer Network has recommended the company’s radioactive microspheres in its Clinical Practice Guidelines in Oncology for colon cancer and rectal cancer. The NCCN panel uniformly agreed that selective internal radiation therapy with yttrium-90 microspheres is an option for patients with metastatic, chemotherapy resistant colorectal cancer. The recommendation was supported by the More retrospective analysis study, which included 600 patients with colorectal cancer. The data suggested that selective internal radiation therapy using Y-90 m...

Liver metastases are often the dominant site of metastatic disease in colorectal cancer. Selective internal radiation therapy (SIRT) involves embolising radiolabeled spheres (SIR-Spheres) into the arterial supply of the liver. This review assesses the effectiveness and toxicity of SIRT in the treatment of metastatic colorectal cancer liver metastasis when given alone or with systemic or regional hepatic artery chemotherapy. We reviewed only randomised controlled trials comparing SIRT and chemotherapy (systemic and/or regional) with chemotherapy alone, or comparing SIRT alone with best supportive care.

Authors: Siavashpour Z, Aghamiri MR, Jaberi R, Manshadi HR, Ghaderi R, Kirisits C Abstract PURPOSE: To analyze the optimum organ filling point for organs at risk (OARs) dose in cervical cancer high-dose-rate (HDR) brachytherapy. MATERIAL AND METHODS: In a retrospective study, 32 locally advanced cervical cancer patients (97 insertions) who were treated with 3D conformal external beam radiation therapy (EBRT) and concurrent chemotherapy during 2010-2013 were included. Rotterdam HDR tandem-ovoid applicators were used and computed tomography (CT) scanning was performed after each insertion. The OARs delineation an...
