New NCCN cancer treatment guidelines expand use of tumor-targeting Y-90 radiation treatment to patients with liver dominant, chemotherapy resistant colorectal cancer
March 2, 2017
HOUSTON — Radiologists from Synergy Radiology Associates (SRA) are now treating Houston-area patients with colon cancer that has spread to the liver, using an advanced treatment for inoperable liver tumors. Originally indicated for inoperable liver cancer, new national cancer guidelines allow for the use of Selective Internal Radiation Therapy (SIRT) in patients with liver dominant, chemotherapy resistant colorectal disease.
“This treatment offers new hope to patients suffering from this difficult disease,” said SRA interventional radiologist Michael Richter, M.D. “For radiologists, this updated guideline means we have another tool in our arsenal for treating a very challenging cancer diagnosis.”

SIRT is an interventional radiology procedure that delivers millions of tiny, radioactive SIR-Spheres® microspheres through blood vessels directly to the tumor site. Developed by Sirtex Medical Limited (ASX: SRX), SIR-Spheres is now included as a Category 2A recommended treatment in the latest National Comprehensive Cancer Network® (NCCN®) Clinical Practice Guidelines for colon cancer and rectal cancer.
“SIRT is an important part of a multidisciplinary approach to liver cancer that can help improve quality of life with fewer side effects, and we’re excited to make it available to area patients,” said SRA President Walid Adham, M.D. “We will continue to look at new treatments that provide advantages over current treatments that can benefit our referring physicians and their patients.”
SIR-Spheres microspheres are the only fully FDA-approved microspheres for colorectal cancer that has metastasized to the liver. The NCCN Category 2A designation means there is uniform consensus among the NCCN panel that SIRT with yttrium-90 (Y-90) microspheres is an appropriate option in chemotherapy resistant patients whose colorectal disease has spread to the liver. The recommendation also places SIR-Spheres on par with recommended metastatic colon cancer chemotherapy treatments.
SRA radiologists are now performing the procedure at Memorial Hermann The Woodlands Hospital, Memorial Hermann Southwest Hospital, and Memorial Hermann Southeast Hospital. Most patients are usually able to go home four to six hours after the procedure, and the reported side effects are few. Patients experience mild, flu-like symptoms for a period of one to two weeks after the procedure. SIRT can be used for primary liver cancers as well as metastatic disease in the liver, including colorectal and breast cancer.

Tiny plastic spheres target inoperable liver tumors in conjunction with chemotherapy
September 26, 2016
HOUSTON — Radiologists from Synergy Radiology Associates (SRA), which provides the highest level of minimally invasive expertise in the Houston metropolitan area, are performing a new, advanced treatment for inoperable liver tumors. The minimally invasive treatment, Selective Internal Radiation Therapy (SIRT) or Y-90 radioembolization, can be performed along with chemotherapy.
“SIRT is an important component to the multidisciplinary approach to liver cancer, and we are excited to be able to offer it to our patients,” said SRA interventional radiologist Michael Richter, M.D. “This minimally invasive procedure has shown promising results in controlling liver cancer while maintaining a good quality of life for the patient.”

During SIRT treatment, millions of SIR-Spheres® microspheres are delivered through blood vessels directly to the tumor site.
SRA radiologists are now performing the procedure at Memorial Hermann The Woodlands Hospital and Memorial Hermann Southwest Hospital. Most patients are usually able to go home four to six hours after the procedure, and the reported side effects are few. Most patients experience flu-like symptoms for a period of one to two weeks after the procedure. SIRT can be used for primary liver cancers as well as metastatic disease in the liver, such as colorectal and breast cancer.
“We’re always looking at new treatments that provide the most benefit for referring physicians and their patients,” said SRA President Walid Adham, M.D. “Our radiologists provide the highest level of minimally invasive expertise in Houston, and we’re pleased to help make this new procedure available to Houston area residents.”
Often used for both primary and metastatic tumors in the liver, SIR-Spheres microspheres are the only fully FDA-approved microspheres for colorectal cancer that has metastasized to the liver.

Cites concerns that confusing, flawed guidelines could result in women losing access to life-saving annual mammograms
December 9, 2015
HOUSTON — Synergy Radiology Associates (SRA), the largest private radiology practice in the Houston metropolitan area, said it supports annual screening mammography for breast cancer starting at age 40, in agreement with most professional medical society guidelines. Furthermore, the radiology group supports the Protecting Access to Lifesaving Screenings Act (PALS Act). The federal legislation would delay proposed U.S. Preventive Services Task Force (USPSTF) recommendations against annual screening mammograms for women age 40 to 49.

The radiology group’s announcement comes in the wake of recently updated American Cancer Society (ACS) guidelines that said women could wait until age 45 to start annual breast cancer screening. That’s contrary to American College of Radiology (ACR), Society of Breast Imaging (SBI), American College of Obstetricians and Gynecologists (ACOG) and other major medical organization guidelines. The ACR and SBI jointly support passage of the PALS Act.
SRA radiologist Reena Vashi, M.D., is concerned about the mixed messages being sent to women, health care providers and insurance companies, which increase the possibility of women losing access to life-saving mammograms.
“Let’s clear up the confusion: getting a mammogram once a year, every year, starting at age 40 is the best way to decrease a woman’s risk of dying from breast cancer,” said Vashi, who is subspecialty trained in breast and body imaging and serves as chair of the Breast Program Leadership Committee at Clear Lake Regional Medical Center. “The goal of mammography is to detect breast cancer at the earliest stage, when it is the most treatable. All major professional medical organizations, including the ACS and USPSTF, agree that screening mammography between age 40 and 50 saves lives.”
Critics of annual screening mammograms raise concerns about potential harms of annual screening before age 45, including overdiagnosis, false alarms and increased anxiety. Vashi and others say the clinical data overwhelmingly supports the fact that the benefits of screening and early detection outweigh the potential harms in the 40-to-50 age group, while the USPSTF ignores recent science that shows annual screening mammography to be far more effective than older studies that were considered by the task force.
“Not a single major professional organization recommends against annual screenings in this age group, and overdiagnosis is a misnomer,” explained Vashi. “As radiologists, our responsibility is to use the best evidence-based screening guidelines to accurately detect and diagnose breast cancer, and it starts with screening at age 40.”
The ACR, SBI and ACS all agree that overdiagnosis claims are vastly inflated due to flaws in numerous clinical trials, and any overdiagnosis that does occur is primarily due to one particular type of cancer called ductal carcinoma in situ (DCIS). In fact, very few invasive cancers are overdiagnosed, and no evidence shows that an invasive cancer has ever gone away or has shrunk without treatment. Additionally, new technologies such as 3-D digital mammography (tomosynthesis), also ignored by the USPSTF, are helping to decrease false alarms even further while achieving a higher cancer detection rate.
“We are committed to providing our patients with the highest caliber radiology services available, and that includes following the most widely accepted breast cancer screening guidelines that provide the most benefit and will save the most lives,” said SRA President Walid Adham, M.D. “While well-intentioned, the ACS guidelines have been oversimplified in news reports and have, along with recent USPSTF actions, had the effect of confusing the issue of annual screening mammograms.”
More information about breast cancer screening facts and guidelines is also available at the ACR’s Mammography Saves Lives website.
