UNC Lineberger cancer researchers to present findings at ASCO annual meeting

UNC Lineberger members were authors on nearly 30 abstracts that will be presented at the American Society of Clinical Oncology (ASCO) annual meeting in Chicago being held May 29-June 2, 2015.

UNC Lineberger Comprehensive Cancer Center researchers will share their expertise and research findings at the American Society of Clinical Oncology annual meeting, which is expected to draw thousands of oncology professionals from around the world to Chicago Friday through June 2.

UNC Lineberger members were authors on nearly 30 abstracts that will be presented at the meeting. Their studies include early findings from a trial testing a specific chemotherapy combination in people with head and neck cancer to an investigation into the impact of race and insurance status on prostate cancer treatment.

Early findings from abstracts that will be presented at the meeting include:

Chemotherapy improves access to breast conservation surgery, but many women still choose mastectomy

With new drug combinations, UNC Lineberger researchers and partners have found in a new study that they could improve the rates of patients with two different types of breast cancer who are eligible for breast conservation surgery. Yet, they also found that a substantial number of women still chose mastectomy.

Building off of a similar study that evaluated the impact of drug combinations in women with triple-negative breast cancer, the study led by Mehra Golshan, MD, director of Breast Surgical Services at Dana-Farber/Brigham and Women’s Cancer Center, looked at the impact of treatment combinations in women with triple-negative and HER2-positive breast cancer. Golshan is also director of Breast Surgical Services at the Susan F. Smith Center for Women’s Cancers at Dana-Farber Cancer Institute

“With this research, we’ve shown that we can offer breast-conserving therapy to more women in both triple-negative and in HER2-positive breast cancer,” said David Ollila, MD, the James and Jesse Millis Distinguished Professor of Surgery at the UNC School of Medicine, co-director of the UNC Breast Program, a UNC Lineberger member and the study's senior author. “The surgery is successful in most women who choose it. Yet, this study also shows that a significant number of women continue to choose mastectomy.”

The preliminary findings will be presented in an oral abstract session that will be held from 3 to 6 p.m. Monday, June 1. More information.

With lower intensity chemoradiotherapy, most cancer free in HPV-positive oropharyngeal cancer subgroup

UNC Lineberger researchers are releasing preliminary results of a new study evaluating whether lower doses of radiation and chemotherapy treatments can be given successfully to a subgroup of patients with oropharyngeal cancer of the tonsil and base of tongue. The study builds on previous research that’s shown that oropharyngeal cancer patients who test positively for human papillomavirus (HPV) have higher response rates to radiation and chemotherapy, excellent cancer control rates, and better overall survival than patients whose cancer is HPV-negative.

For the study, 43 patients were included who had favorable-risk, HPV-or-p16-positive oropharyngeal squamous cell carcinomas.

“This study shows really promising preliminary data that suggests that we are probably over-treating these patients with the standard radiation and chemotherapy regimens,” said Bhishamjit S. Chera, MD, a UNC Lineberger member, an assistant professor in the UNC School of Medicine Department of Radiation Oncology and the study’s first author and principal investigator. “We have shown that we may be able to safely lower the radiation and chemotherapy doses, while still maintaining excellent cancer control, and at the same time, reducing toxicity.”

The abstract will be presented at ASCO’s annual meeting during a Monday, June 1, session at 2:30 p.m. More information.

Study looks at disparities in prostate cancer treatments based on race, insurance status

A UNC Lineberger-led study compared the level of prostate cancer treatment for thousands of men in the United States to investigate whether they were treated less aggressively and received less advanced treatment based on their race or insurance status.

The study, whose senior author was Ronald Chen, MD, MPH, a UNC Lineberger member and an associate professor in the UNC School of Medicine Department of Radiation Oncology, analyzed National Cancer Data Base data for 12,778 men aged less than age 65 years.

The early findings will be presented in a poster session from 1:15 to 4:45 p.m. Monday, June 1.  More information.
