PARIS and SINGAPORE, October 6, 2016 /PRNewswire/ --

Cancer researchers from Assistance Publique - Hôpitaux de Paris (AP-HP) and The Asia-Pacific Hepatocellular Carcinoma Trials Group (AHCC), National Cancer Centre Singapore (NCCS) and Singapore Clinical Research Institute (SCRI) announced that they will collaborate on a prospective meta-analysis that will combine the impending results of two large, randomized controlled studies of Y-90 resin microspheres versus sorafenib. The two studies, which have completed patient recruitment, enrolled approximately 800 patients with advanced primary liver cancer (hepatocellular carcinoma or HCC).

The French HCC study, called SARAH, sponsored by AP-HP with the financial support of the company Sirtex, and the Singapore HCC study, called SIRveNIB (AHCC protocol 06), which also received financial support from Sirtex, use similar research designs to compare the efficacy, safety profiles and quality of life (QoL) of selective internal radiation therapy (SIRT) with liver-directed Y-90 resin microspheres and sorafenib, a systemic chemotherapy treatment that is the current standard of care in advanced hepatocellular carcinoma. HCC patients enrolled in SARAH and SIRveNIB were ineligible for potentially curative therapies, such as surgical resection, ablation or liver transplantation and had either failed or were unsuitable for treatment with Trans-Arterial Chemo-Embolisation (TACE).

Professor Pierce Chow, Principal Investigator of the SIRveNIB study, and Senior Consultant Surgeon at the National Cancer Centre Singapore and the Singapore General Hospital, explained that, "As we stated when we first announced completion of enrolment in SIRveNIB, the search for more effective and better tolerated treatments of HCC is important because so few proven treatment options currently exist. Our study enrolled more than 360 patients from 27 specialist centres in 10 Asia-Pacific countries. While our data will be reported independently, the opportunity to combine these data in a prospective meta-analysis with the results of the French SARAH study presents a compelling scientific undertaking across a much larger patient population that will significantly increase the data available for various pre-planned statistical analyses, including overall survival. This should provide physicians who treat HCC with even greater certainty of the applicability of our results in the treatment of this increasingly common and deadly cancer."

Professor Valérie Vilgrain MD, PhD, Principal Investigator of the SARAH study, Head of Department of Radiology, Beaujon Hospital AP-HP, and Professor at the Université Paris Diderot, Sorbonne Paris Cité, France, said that "The SARAH study was conducted in more than 25 specialist centres throughout France and is expected to report results in the first half of 2017. While we will also report the results of SARAH independently, we believe a prospective meta-analysis of our findings combined with those of the SIRveNIB study may be very compelling. HCC in France and most of Europe is found in patients whose livers have become cirrhotic primarily from the Hepatitis C virus and alcohol misuse, while the majority of HCC cases in Asia are triggered initially by the Hepatitis B virus. Thus, our prospective meta-analysis will provide safety and efficacy data on patients who presented with a full range of the major HCC aetiologies, potentially increasing the clinical applicability of the study results."

Results of the prospective meta-analysis are expected to be available in 2017. In the interim, further details regarding the methodological and statistical approach to the meta-analysis are to be published in a peer-reviewed journal.

About Hepatocellular Carcinoma  

Hepatocellular carcinoma (HCC) is the most common form of primary liver cancer - cancer that starts in the liver - which is the sixth most-common cancer in the world and the second most-common cause of cancer-related death. It affects mainly patients with cirrhosis from any cause, including viral hepatitis and alcohol abuse. HCC occurs with greatest frequency in regions where hepatitis is most often diagnosed, such as in the Asia Pacific region and Southern Europe. When diagnosed in its early stages, HCC can be treated by surgical resection, ablation or liver transplantation with expectation of improved long-term survival. However, these options are not available to the great majority of patients. For patients with unresectable HCC, the outlook is bleak, with survival ranging from a few months to about two years depending largely on the extent of their tumours and state of their liver at the time of diagnosis. No new HCC treatment option has been tested successfully in large studies for almost a decade.

About AP-HP, Greater Paris University Hospitals  

Beaujon Hospital, the principle centre of the SARAH study is part of the Public Hospital System of the City of Paris, AP-HP. The AP-HP is affiliated with a university and has a European dimension that is recognised worldwide.

It assures public health service for everyone, 24/7; this is its pride and purpose. The AP-HP is the largest employer of the Ile de-France: 95,000 people - physicians, researchers, paramedics, administrative personnel and workers - are employed there. Its teams also pursue an important clinical research activities. In 2015 its teams conducted more than 3,400 research projects, and published more than 9100 scientific publications, accounting for 40% of all French medical research publications. The AP-HP holds a portfolio of 825 active international patents. For more information, visit the AP-HP website at http://www.aphp.fr/international
