Five Grants Presented to UAMS Cancer Researchers
Jan. 29, 2018 | Five newly awarded grants will assist scientists at the UAMS Winthrop P. Rockefeller Cancer Institute in their search for new and innovative cancer treatments.
The grants of $10,000 each were presented to young investigators by the Envoys, a volunteer advocacy group of the Cancer Institute Foundation, during their “Doctor is In” reception and research poster showcase Jan. 25.
The grants are made possible by the Envoys’ annual RockStar Lounge fundraiser. This year’s event is set for April 13 at Cajun’s Wharf in Little Rock and will feature a performance by Bon Jovi tribute band Slippery When Wet.
“In an era when research funding has become more and more scarce, we are grateful to the Envoys for providing this essential support for our scientists,” said Cancer Institute Director Peter Emanuel, M.D. “With these start-up funds, they are able to establish the preliminary data needed to secure additional larger grants in the future.”
Recipients of the grants were:
- Marie Burdine, Ph.D., assistant professor in the Department of Surgery, UAMS College of Medicine
Burdine’s project focuses on a novel approach to regulating a protein known as ATAD2 that is highly expressed in several types of cancer, including breast, pancreas, colon and liver, as well as in metastatic disease. If successful, regulation of the protein could lead to new therapies for these types of cancer.
- Brendan Frett, Ph.D., assistant professor in the Department of Pharmaceutical Sciences, UAMS College of Pharmacy
Precision lung cancer treatment is often effective only for the short term due to significant differences that appear in individual cases of the disease. Frett’s objective is to improve the long-term outcomes of precision lung cancer therapy by simultaneously targeting multiple facets of the disease. He will synthetically engineer single molecule drug candidates capable of impairing multiple tumor survival pathways.
- Samantha Kendrick, Ph.D., assistant professor in the Department of Biochemistry and Molecular Biology, UAMS College of Medicine
Kendrick’s project focuses on understanding how and why certain genes repeatedly mutate and contribute to the aggressive nature of B-cell lymphoma. Her research examines the frequency of DNA structures in these specific gene targets and whether the structures contribute to an increased susceptibility to mutation. Uncovering this process can facilitate the design of new therapies to minimize the risk of chemotherapy resistant disease.
- Analiz Rodriguez, M.D., Ph.D., assistant professor in the Department of Neurosurgery, UAMS College of Medicine
Although advances in immunotherapy have offered great promise for several types of cancer, outcomes for an aggressive form of brain cancer known as glioblastoma remain grim. Rodriguez’s project uses the surgical technique laser thermal ablation in combination with immunotherapy to alter the immune microenvironment, cause cancer cell death and open the area around the tumor in an effort to improve outcomes for patients with this disease.
- Erming Tian, Ph.D., M.B.A., assistant professor in the Department of Internal Medicine in the UAMS College of Medicine
Tian’s research addresses the role of two alias proteins produced by the gene MYC in the outcome of patients with multiple myeloma. He seeks to understand how one of these proteins affects the other in regard to cell proliferation and will use this knowledge to deliberately induce a different translation and modification of the gene that could ultimately lead to preventing uncontrollable cancer growth.
Clinical Trial Promising for Ovarian Cancer Treatment
Jan. 18, 2017 | Eighteen years ago, Gail Clayton received news that changed her life. Looking back, she says finding out she had breast cancer marked the beginning of new perspectives.
“When I was first diagnosed with cancer, it wasn’t the end of life as so many people think. To me, it was the beginning of life.”
Clayton and her husband, Raymond, have been married 46 years. He calls UAMS one of Arkansas’ best kept secrets.
“I don’t think people realize how amazing this institution is,” Clayton said. “You become friends with your doctors and nurses. It takes a village and I believe that village is right within these walls at UAMS.
She had breast cancer twice and was recently diagnosed with ovarian cancer. That prompted Clayton’s oncologist, Laura Hutchins, M.D., to refer her to gynecologic oncologist Kristin Zorn, M.D.
“Anytime we see a patient with a new diagnosis of cancer in the ovaries, fallopian tubes or the peritoneum (the internal lining of the abdomen), we think of a possible hereditary source for that cancer,” Zorn said.
Clayton and Zorn discussed genetic counseling and ultimately found Clayton had a mutation in one of the BRCA genes, commonly known as the breast cancer genes. Every person is born with the BRCA1 and BRCA2 genes, but women who inherit mutations of the genes have an increased chance of developing breast, ovarian, and other cancers.
Researchers’ knowledge about these genetic mutations has helped lead to development of a new class of drugs known as PARP inhibitors.
“PARP inhibitors capitalize on the genetic defect that’s already present in people who carry one of these mutations,” Zorn said. “It helps to kill the cancer cells that are accumulating DNA damage.”
There are three types of PARP inhibitors that have been FDA-approved over the past few years: olaparib, rucaparib and niraparib. Clayton is a part of a clinical trial that includes her taking olaparib.
“With PARP inhibitors, we first focused on people who carry a BRCA or similar mutation. We’re now finding many patients with ovarian cancer who do not have a mutation are responding to the drugs.”
Another advantage of this new class of drugs is that they can be taken orally rather than through intravenous infusion, making it more convenient for patients. This works especially well for Clayton who spends a great deal of her time seeing the world.
“If someone says go, we pack a bag and go.”
Since her first diagnosis, Clayton says she takes nothing for granted and began living in a way she may not have if not for the illness. She and Raymond Clayton have made lots of memories abroad. Sometimes their adult son Randy joins them.
“We’ve been to the Baltic States, Russia, Berlin, Sweden…”
She’s responded well to the clinical trial and shows no indications of slowing down.
“…England, Paris, the Caribbean, Ireland. It’s been a journey.”
“Part of the reason I’m so passionate about practicing at a place like UAMS, is that it helps us bring cutting-edge therapies to our patients,” Zorn said. “Sometimes we’re talking about a surgical advance, sometimes we’re talking about an advance in treatment.”
Zorn says genetic counseling and testing has become a standard of care in some of the most common gynecological cancers.
“While many parts of the country are having trouble keeping up with the change in the standard of care, UAMS has a genetic counselor embedded in our clinic so that we can accomplish that.”
“The way I see it,” said Clayton, “Even if the clinical trial didn’t work for me, maybe it would work for someone else. I’m grateful for the strides scientists have made in treating this disease.”
This clinical trial was developed through the NRG Oncology cooperative trial group of the National Cancer Institute. The only access to this trial in Arkansas is at UAMS.

Study Shows Key Molecular Differences in Childhood Acute Myeloid Leukemia Could Lead to Better Treatment
LITTLE ROCK – A scientist at the University of Arkansas for Medical Sciences (UAMS) is among the lead authors of a study that could lead to more effective therapies for children with acute myeloid leukemia (AML).
UAMS’ Jason Farrar, M.D., and collaborators at eleven other institutions published their study in the journal Nature Medicine and presented findings at the 2017 American Society of Hematology Annual Meeting (ASH) held Dec. 9-12 in Atlanta. Many of the published results were first released at the 2016 ASH Annual Meeting, held in San Diego.
“Although research has made great strides in improving survival rates for children with acute lymphocytic leukemia, progress in AML, a less common less form of childhood leukemia, has lagged behind. Our research is a step forward in understanding how to better treat children with this challenging disease,” said Farrar, assistant professor in the UAMS College of Medicine Department of Pediatrics.
The study’s findings identified key differences between the molecular structure of AML in young patients as opposed to those who are older. Due to these differences, the researchers concluded that traditional therapies used to treat adults with AML are not effective for children and young adults with the same disease.
“One of our key findings is that there is a clear age continuum in the biology of AML. Because the disease develops differently in the young, middle aged and old, we know that we can’t use the previously accepted therapies that were designed for older adults and expect them to have the same outcomes for children and young adults,” Farrar said.
The study involved an analysis of the genomes of more than 1,000 AML patients treated nationwide through the Children’s Oncology Group, with ages ranging from 8 days to 29 years. Of that number, 200 had their entire genome sequenced for the study, however the group’s continuing research includes whole-genome sequencing for hundreds more participants.
Data also was gathered from about 400 of these patients to determine how their cancer cells read and interpreted the DNA changes.
“We need high-depth data on every AML patient we treat to get the best possible understanding of how this disease works at a molecular level,” Farrar said.
Most commonly diagnosed in older adults, AML starts in the bone marrow and can move quickly to the blood. According to the American Cancer Society, about 21,000 Americans are diagnosed with AML each year and about 10,600 die of it. As stated in the researchers’ paper, four out of 10 young AML patients do not survive long term.
Based on their findings, Farrar and his collaborators have already developed an improved system for determining the severity of AML in young people at the time of their diagnosis. The individual patient’s treatment is then tailored to the severity of their disease, with those who have less severe disease receiving treatment with fewer possible side effects.
This system is implemented at Seattle Children’s Hospital, where collaborator Soheil Meshinchi, M.D., of Fred Hutchinson Cancer Research Center, sees patients and will soon be integrated into national cooperative clinical trials for children and young adults with AML.
“Being able to identify whether a child has high-risk or low-risk disease is very important to their long-term outlook. For example, many of the drugs used to treat AML can cause young patients to have cardiac conditions as they age. If we can effectively treat their cancer with drugs that do not damage their heart, we definitely want to do that,” Farrar said.
Funded by the National Cancer Institute, this research effort is part of a program called the TARGET Initiative, which is focused on determining the genetic changes that drive the formation and progression of hard-to-treat childhood cancers. TARGET stands for Therapeutically Applicable Research to Generate Effective Treatments.
In addition to AML, the TARGET Initiative researchers also study acute lymphoblastic leukemia, kidney tumors, neuroblastoma and osteosarcoma.
Additional support for this study comes from the Arkansas Biosciences Institute, the Center for Translational Pediatric Research at Arkansas Children’s, Scientific Computing at Fred Hutchinson Cancer Research Center, the University of Southern California’s Center for High-Performance Computing, St. Baldrick’s Foundation and the Jane Anne Nohl Hematology Research Fund.
In addition to Farrar and Meshinchi, the paper’s lead authors include Hamid Bolouri, Ph.D., and Rhonda E. Ries of Fred Hutchinson Cancer Research Center and Timothy Triche Jr., M.D., Ph.D., of the Van Andel Research Institute and University of Southern California Norris Comprehensive Cancer Center.
Little Rock Man Beats Cancer Twice with Help of UAMS
Dec. 18, 2017 | After 40 years, Jerry and Sharon Moskwiak were ready to leave the cold Michigan winters behind.
They considered a move to their favorite vacation spot in South Carolina, but there was one catch: The nearest academic health care center was at least one hour away.
Because Sharon had worked for 35 years at the University of Michigan, including several years in their medical school, the couple was familiar with the advantages of receiving health care in an academic research setting.
And, because Jerry was a 25-year lung cancer survivor and lived with other chronic illnesses, access to quality health care was one of their top requirements when searching for a new place to call home.
That’s when they turned their sights to Little Rock.
“I grew up in Little Rock and knew the health care was exceptional. That was one of the main reasons we decided to move back here,” Sharon said.
After getting settled into their new home, the Moskwiaks set about finding a primary care physician. Their first and only stop was at the University of Arkansas for Medical Sciences (UAMS), Arkansas’ only academic health care center. During one of his initial appointments, Jerry received some unexpected news that convinced them they had made the right move at the right time.
“The doctor noticed a spot on my chest X-ray, and the next thing I knew we were discussing a plan for chemo,” Jerry said.
The spot was diagnosed as a subtype of non-Hodgkin lymphoma known as mantle cell lymphoma (MCL). This type of lymphoma can be fast growing and is most commonly found in men older than 60.
He was referred to Appalanaidu Sasapu, M.D., a hematologist oncologist at the UAMS Winthrop P. Rockefeller Cancer Institute, who scheduled him for six rounds of chemotherapy to occur every 28 days. Sasapu also is an assistant professor in the Department of Internal Medicine in the UAMS College of Medicine.
“Dr. Sasapu was very clear and told us exactly what his course of action would be. He was confident that what he was prescribing would work for me, and he was right,” said Jerry.
In fact, after Jerry’s fifth round of chemo in October 2016, Sasapu gave the couple good news: The treatment was successful, and he did not need to receive the final round.
“I’m very happy with Mr. Moskwiak’s progress. He is a wonderful gentleman who always has a smile on his face, and his wife is a great caregiver for him,” Sasapu said.
Unfortunately, the good news was short lived when a follow-up scan revealed that Jerry was now facing another challenge: His lung cancer had reappeared after 25 years.
“The first time Jerry was diagnosed, he had surgery to remove the upper lobe of his right lung. This time the spot was in the lower lobe of his left lung, and he wasn’t a candidate for surgery due to his other health concerns,” Sharon said.
After an unsuccessful attempt to freeze the tumor with cold gases in a process called cryoablation, Jerry began a course of radiation therapy under the direction of Sanjay Maraboyina, M.D., assistant professor in the Department of Radiation Oncology in the UAMS College of Medicine.
“Just like Dr. Sasapu, Dr. Maraboyina had a very positive attitude and prescribed an aggressive treatment plan. They both kept the ball rolling in the right direction,” Jerry said.
Maraboyina recommended a highly precise treatment known as stereotactic body radiotherapy at the UAMS Radiation Oncology Center targeting the spot on his lung. This was again good news as only three treatments were required instead of a daily course over several weeks.
“Dr. Maraboyina was a godsend. The care I have received has been exceptional,” Jerry said.
Although both cancers are now in remission, Sasapu recommended Jerry undergo maintenance therapy with the immunotherapy drug Rituxan every two months for two years to keep the lymphoma at bay. With about one year left on that regimen, he is proud to say he feels great. “I’m more than happy with this outcome,” Jerry said.
Faith in Cancer Care Team Keeps New Mexico Woman at UAMS
Dec. 1, 2017 | Tina Farber arrived in Arkansas with one thing on her mind — meeting her two new grandbabies. Her son’s third child had arrived in April, and her daughter was expecting her third about one month later.
“I was planning to stay about two months,” said Farber, a native Arkansan who now lives in New Mexico. “I had a PET scan scheduled for July 7 and needed to return home in time for that.”
A stage 3 lung cancer survivor, Farber was considered to be in remission following surgery, chemotherapy and radiation in 2016. The PET scan was a routine follow-up to ensure the cancer had not returned.
Her plans were about to change, however, when she soon developed a cough, headache and fever, prompting a trip to the urgent care clinic. After returning to her daughter’s house with a diagnosis of pneumonia, Farber’s fever shot up to 102.4 degrees and the family took action.
“My daughter, Brittney, said to pack my bags. She was taking me to the hospital,” said Farber.
About a year earlier, while still undergoing chemotherapy, Farber also had made a visit to Arkansas. A bout with dehydration during her stay landed her in the UAMS Emergency Department, where she was impressed with the doctors and nurses who attended to her.
“Everything was in sync. They got me all taken care of. I told my kids that if I’m ever visiting again and need to see a doctor, don’t take me anywhere but UAMS,” she said.
After making the hour-long drive from her daughter’s home in Malvern, Farber again arrived at UAMS where she was quickly admitted and given the attention of a team of health care providers.
“Before I even got my wristband, they called me to triage and then immediately put me in a room where six people were waiting to take care of me. I was blown away,” she said.
After a series of tests, the doctor arrived with unexpected news. Lesions were found in her brain and bones that likely meant the lung cancer had spread.
“Once we found out the tumor had progressed to the brain and bones, we immediately got Mrs. Farber’s team together to carefully review her case and formulate an overall treatment plan,” said Fen Xia, M.D., Ph.D., chair of the Department of Radiation Oncology in the UAMS College of Medicine.
That team included Xia, who specializes in radiation therapy for brain cancer; medical oncologist Konstantinos Arnaoutakis, M.D., who specializes in lung cancer; and orthopedic oncologist Corey Montgomery, M.D., who specializes in bone cancer. Other specialists in neurology and neurosurgery also were consulted as the treatment plan took shape.
“Having a team of physicians who work together efficiently and in a timely manner is particularly critical in cancer patient care. At the UAMS Cancer Institute, our doctors and nurses communicate instantly and continuously to coordinate our patients’ care at every step, from diagnosis and care management planning to treatment delivery,” said Xia, who also works closely with nurse practitioner Nikki Baxter, A.P.R.N., at the UAMS Radiation Oncology Center.
Because radiation therapy requires daily treatments, Baxter is available to assist patients with symptom management and other issues that arise on a day-to-day basis.
“Communication and accessibility are the top priority with our patients. We all work together to provide the best care possible,” Baxter said.
That emphasis on communication and coordination have lightened the load for Farber and convinced her to postpone returning to New Mexico in favor of continuing treatment in her home state at the UAMS Winthrop P. Rockefeller Cancer Institute.
“It’s hard to be away from my husband, but God put me here for a reason,” said Farber, who added that her family and long-time friends have offered endless support and encouragement during her extended stay in Arkansas.
“The doctors and nurses at UAMS have taken the time to get to know me. They all know my story, which is really important to me. I’m going to stay here and fight this battle because I know I’m in good hands,” Farber said.
UAMS Breast Surgeon Ronda Henry-Tillman, M.D., Named to Kohn Chair in Breast Surgical Oncology
Nov. 30, 2017 – Ronda Henry-Tillman, M.D., F.A.C.S., was invested Nov. 29 as recipient of the Muriel Balsam Kohn Chair in Breast Surgical Oncology at the University of Arkansas for Medical Sciences (UAMS). She is chief of Breast Oncology in the UAMS College of Medicine Department of Surgery.
The endowed chair is the result of a gift from the Tenenbaum Foundation. The foundation’s primary objectives include providing humanitarian assistance to residents of central Arkansas, promoting awareness of breast cancer, and funding research to reduce or eliminate deaths from the disease.
The chair is named in honor of Muriel Balsam Kohn, mother of Judy Tenenbaum, who died of breast cancer in 1993.
“I am thankful for the generosity and foresight of the Tenenbaum Foundation in establishing this endowed chair, which has enabled valuable breast cancer research to be conducted in Arkansas for the past 10 years. This legacy will continue for many years to come through the work and dedication of Dr. Henry-Tillman,” said UAMS Interim Chancellor Stephanie Gardner, Pharm.D., Ed.D., who also serves as senior vice chancellor for academic affairs and provost.
An endowed chair is among the highest academic honors a university can bestow on a faculty member and is established with gifts of $1 million, which are invested and the proceeds used to support the educational, research and clinical activities of the chair holder. Those named to a chair are among the most highly regarded scientists, physicians and professors in their fields of expertise.
“Dr. Henry-Tillman has been a valuable member of the UAMS faculty since 1998, not only serving as a knowledgeable and caring physician for countless women, but also as a tireless advocate for underserved Arkansans who lack basic health care services. There is no doubt that her work to improve access to mammography services has extended the lives of women across our state,” said UAMS Cancer Institute Director Peter Emanuel, M.D., who also serves as professor of medicine in the UAMS College of Medicine.
NBA Hall of Famer and philanthropist Dikembe Mutombo addressed the attendees gathered to honor Henry-Tillman at a Nov. 29 ceremony, praising her work at educating health providers in Africa, including at the Biamba Marie Mutombo Hospital he founded 10 years ago in the Democratic Republic of the Congo.
Henry-Tillman’s mentor, Groesbeck P. Parham, M.D., recruited her to travel to Africa where she has taught breast surgical techniques and medical procedures to health care providers who have limited access to equipment and advanced educational opportunities. Parham is a professor of obstetrics and gynecology at the University of North Carolina, Chapel Hill.
After earning her medical degree at the University of California San Diego School of Medicine, Henry-Tillman completed her surgical residency in the UAMS Department of Surgery and fellowship training in the UAMS Fellowship in Diseases of the Breast program.
She holds the positions of professor in the Department of Surgery, co-director of Health Initiatives and Disparities Research in the UAMS College of Medicine, and co-leader of the Breast Tumor Disease Oriented Committee in the UAMS Winthrop P. Rockefeller Cancer Institute.
She previously served as director of the UAMS Cancer Control program and was instrumental in the development of the university’s mobile mammography program.
Her research efforts have focused primarily on health initiatives that address access, community-based participatory research, health disparities and health policy in the areas of breast, prostate, colorectal, and cervical cancer prevention.
In 2016, Henry-Tillman was appointed by Gov. Asa Hutchinson to the Arkansas Medical Marijuana Commission and was voted chairman in 2017. She also is a member of the Breast Cancer Control Advisory Board and is a Pulaski County health officer for the Arkansas State Board of Health.
Her memberships and professional activities include the American Surgical Association, Society of Surgical Oncology, Southern Surgical Association, Society of Black Academic Surgeons, National Medical Association, American Society of Breast Surgeons and multiple committees of the National Institutes of Health. She has served as a board member for the National Accreditation Program for Breast Centers and the national Health Disparities Committee for the American Cancer Society, as well as the Arkansas Cancer Coalition and other local organizations.
She has received numerous awards and honors including being named to the Alpha Omega Alpha Honorary Medical Society, Best Doctors in America and Castle Connolly’s Exceptional Women in Medicine. She is recipient of the Shipley Award by the Southern Surgical Association; the Rosetta Wilkins Award by BreastCare; the President’s Award by the Arkansas Medical and Dental Pharmaceutical Association; the President’s Award by the Arkansas Democratic Black Caucus. She also has received the Phenomenal Woman in Science and Excellence in STEM Mentoring awards.
The Tenenbaum Foundation was created in 1964 by Joe M. Tenenbaum. The foundation created the chair’s endowment in 2007 to recognize Kohn and the chair’s first holder V. Suzanne Klimberg, M.D., Ph.D., former director of the UAMS Division of Breast and Surgical Oncology. Klimberg now serves as medical director of the University of Texas Medical Branch Cancer Center in Galveston, Texas.
Speakers at the Nov. 29 ceremony included Gardner, Emanuel, Klimberg, Parham, Mutombo and the following:
- Pope L. Moseley, M.D., UAMS executive vice chancellor and dean of the UAMS College of Medicine
- Kent C. Westbrook, M.D., distinguished professor of surgery in the UAMS College of Medicine
- Frederick R. Bentley, M.D., professor and chairman of the Department of Surgery in the UAMS College of Medicine
