They are now testing and perfecting a new technology that could drastically increase the number of lungs suitable for transplant. Egan thinks it could also help surgeons to draw from a new donor pool - people who have died outside the hospital and have not been on life support.
The article also features two of Dr. Egan's lung transplant patients.

Benson Reid Wilcox, M.D., a heart surgeon who served 29 years as chief of the Division of Cardiothoracic Surgery at the University of North Carolina at Chapel Hill, died May 11, 2010, at his home after a courageous battle with brain cancer. He was 77.
Dr. Wilcox served as chief of cardiothoracic surgery at UNC from 1969 to 1998. During that period, which was a time of dramatic advances in heart and lung surgery, the UNC hospital began offering coronary artery surgery, heart and lung transplantation, successful surgery for congenital heart defects in newborn infants, and a comprehensive program for the treatment of lung and esophageal cancer.
Dr. Wilcox was primarily a pediatric heart surgeon whose specialties were congenital heart disease, pediatric cardiac morphology, pediatric chest disease, and pulmonary circulation. He was a co-author of three books and an author of numerous medical journal articles and book chapters. He held important leadership posts in national medical organizations and was especially interested in the training of future surgeons.
Dr. Wilcox, known as Ben, was born May 26, 1932, in Charlotte, N.C., the son of James Simpson Wilcox and Louisa Reid Wilcox. He was raised in Charlotte and graduated from the Darlington School in Rome, Ga., in 1949. He was named 1997 Distinguished Alumnus of the Darlington School.
He earned an A.B. in history from the University of North Carolina in 1953 and an M.D. from the UNC School of Medicine in 1957. As an undergraduate at UNC, he was president of Sigma Alpha Epsilon fraternity and Rex of the Order of Gimghoul. At the UNC medical school, he was president of his class and was inducted into the Alpha Omega Alpha medical honor society in 1957.
While a medical student in 1956, Dr. Wilcox helped to conduct laboratory research on the application of newly developed heart-lung machines. A heart-lung machine was first used in the operating room at UNC in April 1957, beginning the era of open heart surgery at North Carolina Memorial Hospital.
After serving as a surgery resident at Barnes Hospital in St. Louis (1957-1959) and North Carolina Memorial Hospital in Chapel Hill (1959-1960), he spent two years as a surgical clinical associate at the National Heart Institute, part of the National Institutes of Health in Bethesda, Md. He then returned to UNC as chief resident in cardiovascular and thoracic surgery (1962-63) and as chief resident in surgery (1963-64).
He joined the UNC Department of Surgery faculty in 1964 and was appointed as chief of the Division of Cardiothoracic Surgery in 1969 and as a full professor in 1971. He was named a Markle Scholar in Academic Medicine in 1967. After he retired as chief of cardiothoracic surgery, Dr. Wilcox remained on the UNC medical school faculty as Professor of Surgery from 1998 until his death.
Dr. Wilcox served the university in a number of other capacities. He was a member of the Selection Committee for the North Carolina Fellows Program; the UNC Faculty Committee on Athletics, serving as chairman from 1977 to 1985; and the Morehead Foundation’s Central Selection Committee, serving as chairman from 1989 to 1992. He was on the university’s Faculty Council and other campus-wide committees. He was a member of the executive committee of the Atlantic Coast Conference from 1978 to 1982 and was its president from 1980 to 1981. He also served on the board of directors of the Ronald McDonald House in Chapel Hill from 1981 to 1999.
He held leadership positions in prestigious professional organizations, including chairman of the American Board of Thoracic Surgery, chairman of the Advisory Council for Cardiothoracic Surgery of the American College of Surgeons, president of the Nathan A. Womack Surgical Society, and president of The Society of Thoracic Surgeons, the largest society of thoracic surgeons in the world. He received the Distinguished Service Award from the Society of Thoracic Surgeons in 2003.
He had a strong interest in graduate medical education, the training of resident physicians. He was instrumental in establishing the Thoracic Surgery Directors Association (TSDA) which was formed to improve cardiothoracic surgery training and education for doctors, and whose members are directors of cardiothoracic surgery residency programs across the United States. From 1985 to 1987, he served as president of TSDA. In 2009, the TSDA honored him by establishing the Benson Wilcox Award for Best Resident Paper, to be presented each year at The Society of Thoracic Surgeons' annual meeting for the best scientific abstract submitted by a cardiothoracic surgery resident.
He also was on the Board of Directors of the National Resident Matching Program from 1998 to 2007, serving as president from 2001 to 2002. He was a member of the Accreditation Council for Graduate Medical Education’s Residency Review Committee for Thoracic Surgery (1999-2005); the American College of Surgeons’ Graduate Medical Education Committee (1993-2001); and a member of the Committee on Graduate Education for the American Association for Thoracic Surgery (1992-2001).
In 1980, Dr. Wilcox spent time during a sabbatical at Royal Brompton National Heart and Lung Hospital in London, beginning a collaboration with Robert H. Anderson, M.D., a pediatric morphologist at Royal Brompton. After that visit, he and Dr. Anderson worked together on many research projects and publications, including the book Surgical Anatomy of the Heart (Raven Press, 3rd edition, 2004). The two physicians established a program that for many years enabled UNC cardiothoracic surgery residents to spend time in London studying with Dr. Anderson and attending rounds with him. Dr. Anderson also visited UNC.
Dr. Wilcox also was co-author of Atlas of the Heart (Gower Medical Publishing, 1988); and a co-editor of Diagnostic Atlas of the Heart (Raven Press, 1994). He was an author of more than 100 scientific and clinical articles that were published in medical journals.
After operating on many ill children, Dr. Wilcox had the idea of starting a support group for families of children who are undergoing heart surgery. The Carolina Parent Network, begun in 1986 and directed by Maggie Morris for many years, enables parents of children who are facing heart surgery at UNC to talk to parents who have already had the experience, and it also educates families about what to expect before, during and after surgery.
Dr. Wilcox loved history, especially medical history. As a medical student at UNC, he helped found the Bullitt Club for the study of the history of medicine. As a faculty member, he began collecting old and rare books about the history of medicine, particularly books about thoracic surgery and the specialties that preceded it. In 1984, he began presenting a rare book to the UNC Health Sciences Library each year in honor of his chief resident. In 1998 and 1999, he donated most of his medical book collection to the library. Since then the Benson Reid Wilcox Collection has grown to more than 1,400 books, journals, reprints and other items. He served on the board of visitors for the UNC Health Sciences Library.
"Dr. Wilcox' contributions to the historical collections at the Health Sciences Library were truly remarkable in both variety and scope. An avid and erudite bibliophile, he thrilled in the hunt for significant texts, and had a deep appreciation for the role of history in the theory and practice of medicine," said Daniel Smith, special collections librarian for the UNC Health Sciences Library.
Dr. Wilcox is survived by his wife, Patsy Davis, and by his four children: Adelaide W. King and her husband, Ruffin, of Charlottesville, Va.; Sandra W. Conway and her husband, Peter, of Charlotte, N.C.; Melissa W. Bond and her husband, Brett, of Charlotte; and Reid Wilcox and his wife, Suzanne, of Greensboro, N.C. He is also survived by 11 grandchildren, Alexandra and Ruffin King; Peter, Ben and Adelaide Conway; Brett, Lucinda and Reid Bond; and Ben, Henry and Ellie Wilcox. He is also survived by two stepdaughters, Harriet Kendall and Julia Klein; a brother, Bob Wilcox; two sisters-in-law, Dede Thompson and Louise Wilcox, and a brother-in-law Allan Davis. He was predeceased by his parents and by his brother Jim Wilcox.
A memorial service was held Friday, May 14, in Gerrard Hall on the campus of the University of North Carolina at Chapel Hill.
In lieu of flowers, the family suggests memorial gifts to the TSDA Benson R. Wilcox Award. Checks can be made to the Thoracic Surgery Directors Association and mailed to Michael R. Mill, M.D., Division of Cardiothoracic Surgery, CB#7065, UNC-CH, Chapel Hill, NC, 27599-7065.

The National Heart, Lung, and Blood Institute has awarded Thomas M. Egan, a professor of surgery at the University of North Carolina, a $1.47 million, two-year grant for research on perfusion and ventilation of lungs outside the body before transplant. The research could lead to a significant increase in the number of lungs available for transplant.
Dr. Egan, a surgeon in the UNC Division of Cardiothoracic Surgery, is internationally known for his research on lung transplantation, which has been under way since he came to UNC in 1989 to start its lung transplant program.
His new grant was awarded under the NHLBI’s Translational Research Implementation Program, a two-stage program designed to translate fundamental research ideas into proof-of-concept efficacy testing in patients. This Stage 1 grant is supported by the American Recovery & Reinvestment Act's Grand Opportunities (GO) grants program, for large-scale research projects that the National Institutes of Health says have “a high likelihood of enabling growth and investment in biomedical research and development, public health, and health care delivery.” NHLBI is part of the National Institutes of Health.
Dr. Egan’s project will perfect a technique to perfuse and ventilate human lungs outside the body (ex vivo) to determine if they are suitable for transplant, and will demonstrate safety of transplanting human lungs after ex-vivo perfusion in a pilot clinical study.
Lung disease is the fourth leading cause of death among Americans. Lung transplantation helps patients with end-stage lung diseases and improves survival, but transplants are critically limited by an inadequate supply of suitable lungs from conventional organ donors – people who have been declared brain-dead after a lethal brain injury and have been on ventilation before a controlled cardiac arrest when organs are retrieved for transplant. Lungs that have been offered for donation frequently cannot be used because lung function in the donor is poor, due to inflammation or infection or fluid build-up (edema) that occur after trauma and emergency treatment.
Even if the lungs are suitable for use, they are still vulnerable to problems. During transplant, the stopping and restarting of circulation to the lungs can cause ischemia-reperfusion injury, which damages cells in the lung and leads to problems with lung function after transplant.
Only about 1,400 lung transplant procedures are performed each year in the United States; since 1995, 6,022 people have died while on the waiting list for lung transplants. This week, 1,867 people were on the national waiting list for lung transplants, according to the Organ Procurement and Transplantation Network, part of the U.S. Department of Health and Human Services.
Dr. Egan has designed an ex-vivo perfusion and ventilation circuit in which lungs are placed for evaluation and possible treatment before transplant. Ex-vivo perfusion and ventilation allow for lung function assessment, and also for possible treatment of lungs to reduce ischemia-reperfusion injury in transplant. Thus, the lungs treated this way could have less graft dysfunction or failure and the transplant recipient could have an improved chance of survival. This would revolutionize lung transplantation, and could have a major impact on other types of organ transplants.
Michael Knowles, M.D., a pulmonologist in the UNC Division of Pulmonary and Critical Care Medicine and a collaborator on Dr. Egan’s project, called the research project “groundbreaking.”
“I have been involved in lung transplantation from its inception at UNC, and have seen, first-hand, the suffering and unnecessary death that results from the shortage of lung donors in the U.S.,” Dr. Knowles said in a letter of support for the research.
The project has support of lung transplant physicians at several other universities in the U.S. and Canada as well as from Carolina Donor Services, the organ procurement organization serving most of North Carolina.
For the Stage 1 project, Dr. Egan’s research team will use lungs from conventional organ donors that have been declined for transplant because of concerns about lung function, as well as lungs from DCD (donation after cardiac death) donors, patients who are not brain dead but whose next-of-kin have decided to withdraw life support because the patient's condition is so poor. The lungs will be assessed and treated in the ex-vivo perfusion and ventilation circuit.
In a Stage 2 study, Dr. Egan’s project will also plan a large multi-center clinical trial to use the ex-vivo lung perfusion/ventilation system to evaluate human lungs retrieved after death from non-heart-beating donors, patients who have died of sudden cardiac arrest outside the hospital or in the emergency room. Using animal models, Dr. Egan was the first scientist to show that lungs could be retrieved from non-heart-beating donors after death and safely transplanted. His research has shown that lungs are viable for substantial periods of time after circulation stops, because lung cells do not rely on perfusion (circulation of blood or other fluids) for cellular respiration.
Widespread use of lungs retrieved from non-heart-beating donors followed by ex-vivo assessment could provide much larger numbers of human lungs for transplant that may function better and last longer than lungs currently being transplanted from conventional brain-dead organ donors.
Investigators for the project, entitled “Ex-vivo perfusion and ventilation of lungs to assess transplant suitability,” are:

In July 2010, the Division of Cardiothoracic Surgery at the University of North Carolina at Chapel Hill will begin a new six-year integrated residency program, which residents will enter directly from medical school. The Residency Review Committee for Thoracic Surgery, the national residency accrediting body, approved the program in July 2009. UNC is one of just a few institutions in the United States that offer such a program.
Students at North American medical schools may apply for the program through the Electronic Residency Application Service (ERAS). The deadline for applying for the 2010 residency has passed, but students may apply from September 2010 to January 2011 for the six-year residency program that begins in July 2011.
The new program will replace UNC’s traditional three-year cardiothoracic surgery residency program and the general surgery residency that precedes it. UNC’s three-year program will be phased out as residents in the integrated six-year program fill the early years of the program.
The three-year residency program will start its final resident in 2013; that person would complete the three-year program in 2016 (application for this position would be in the fall of 2011, with interviews in winter 2011-2012). For more information on the three-year program, click here.
The six-year curriculum includes rotations in vascular interventional radiology, endoscopy, cardiology, and endovascular surgery, and will provide residents with the background and experience using these new techniques in order to build a career as future “cardiothoracic specialists.” The program has been carefully designed to balance cardiovascular and thoracic care, and includes extensive exposure to fields relevant to thoracic surgery such as GI endoscopy, surgical oncology, and gastrointestinal (foregut) surgery. Completion of the program will lead to certification by the American Board of Thoracic Surgery. At UNC, the new program shortens the current ABTS certification process by two years.
Michael R. Mill, M.D., is chief of the UNC Division of Cardiothoracic Surgery and is director of the residency program.
UNC Division of Cardiothoracic Surgery faculty members believe that this tightly focused, comprehensive curriculum will produce better trained cardiothoracic surgeons and will be gratifying to the resident physicians who complete the program.
The field of cardiothoracic surgery has evolved tremendously over the decades, offering patients many more options for the treatment of intra-thoracic disease. The complexity of cardiothoracic surgery has increased and it has become more dependent upon a multi-disciplinary team approach, involving primary care physicians, cardiologists, pulmonologists, anesthesiologists, intensivists, radiologists, pathologists, cardiac perfusionists, nurses, clinical coordinators, social workers, and others. Hence, the objective of this training program is to provide a more comprehensive and rational immersion in the diagnosis and management of all aspects of cardiovascular and thoracic diseases through multi-disciplinary training. All aspects of the new curriculum are based on proven models of education currently available at the University of North Carolina. The curriculum preserves the significant contribution of general surgery and vascular surgery training to the development of a well-rounded cardiothoracic surgeon.

A UNC medical team provided heart surgery for 10 children with complex congenital heart defects during this year's two-week medical mission to Mulago Hospital, Makerere University, in Kampala, Uganda. All of the children were doing well when the UNC team left Kampala on Wednesday, Oct. 7.
This was the third year that the UNC team had visited Uganda, where they are training health care providers at the Uganda Heart Institute. The missions aim to help the pediatric cardiac surgery program become self sufficient in providing care for children with heart disease. The UNC team includes physicians (a pediatric heart surgeon, a pediatric anesthesiologist, a pediatric cardiologist and pediatric intensive care doctors); a pediatric nurse practitioner and a physician’s assistant who specialize in cardiac surgery; operating room and intensive care unit nurses; respiratory therapists; a perfusionist; and a biomedical engineer.
The team members left North Carolina on Sept. 26, carrying 900 pounds of medical equipment and supplies with them on their flight. When they arrived at the hospital in Uganda, the team quickly set up the operating room, perfusion equipment, and intensive care unit. Team members Karla Brown, Ruben Bocanegra, Katherine Desrochers, and Jennifer Ditto had collected and prepared the supplies and equipment for shipment, a months-long process.
Dr. Michael Mill, a pediatric heart surgeon from UNC, performed two operations a day for the first four days of the visit, with one additional operation on Oct. 3, and one on Oct. 5. This year, the children receiving surgery were smaller and younger than those who received surgery on past visits, and this year's patients had more complex congenital heart lesions. Seven of the children who received surgery weighed less than 10 kg (about 22 pounds). The team cared for the children 24 hours a day, overcoming challenges such as brief power outages, equipment breakdowns and repairs, and illnesses of team members.
The children who had the surgery are all recuperating well, and their spirits, energy, and appetites have markedly improved, team members reported. Without surgery, the children would have died from their heart defects; now, they can live normal lives.
The Uganda heart program mission has generous support from Samaritan's Purse and the UNC Institute for Global Health & Infectious Diseases. A team from the Children’s National Medical Center in Washington also participates in Uganda missions. After the UNC team's last mission in October 2008, partners from Children's National Medical Center returned in April 2009 and operated on an additional 10 children while advancing the Uganda program. The Ugandan team in-country has successfully repaired three additional children.
The 2009 UNC team members:
Keith Kocis, MD, UNC pediatric intensive care unit (PICU) physician; team leader
Michael Mill, MD, UNC pediatric heart surgeon
Eugene Freid, MD, anesthesiologist from Nemours Children's Clinic, Jacksonville, Fla.
Stacey Peterson-Carmichael, MD, PICU physician from Duke

The work at Mulago Hospital began after a group of UNC physicians established the Amal Murarka International Pediatric Health Foundation in memory of their colleague, Dr. Amal Murarka, a UNC PICU physician who died in a traffic accident in 2003. The foundation sent a medical team to Kampala to establish the country's first pediatric intensive care unit at Mulago Hospital, where Dr. Murarka had previously conducted research. Subsequent work in 2007, 2008 and 2009 has focused on pediatric cardiac surgery. The teams have established a cardiac ICU and have performed more than 30 life-saving pediatric cardiac surgeries. Team members have trained nurses at the Ugandan hospital in post-surgical care of pediatric heart surgery patients.
In 2008 the Murarka foundation partnered with the Institute for Global Health and Infectious Diseases to establish UNC Project-Uganda.

The Thoracic Surgery Directors Association has renamed its Resident Award the Benson Wilcox Award for Best Resident Paper in honor of Benson R. Wilcox, M.D., former president of the TSDA. Dr. Wilcox is a professor of surgery at the University of North Carolina at Chapel Hill and is emeritus chief of the UNC Division of Cardiothoracic Surgery.
The Best Resident Paper award is presented annually at The Society of Thoracic Surgeons' annual meeting for the best scientific abstract submitted by a cardiothoracic surgery resident.
TSDA is a group of doctors who are directors of cardiothoracic surgery residency programs across the United States. Dr. Wilcox was instrumental in establishing TSDA and drafting the association’s bylaws. Dr. Wilcox, a heart surgeon, is a longtime leader in cardiothoracic surgery education and was TSDA’s first secretary/treasurer from 1977-1980. He also served as president-elect from 1983-1984 and as president from 1985-1986. TSDA was formed to improve cardiothoracic surgery education.
The North Carolina Biotechnology Center has made a $30,000 loan to X-In8 Biologicals Corp., a new biotechnology company founded by Thomas M. Egan, M.D., M.Sc., a faculty member in the Division of Cardiothoracic Surgery at the University of North Carolina at Chapel Hill. The company is a spinoff from work that Dr. Egan has done in his lab at UNC-Chapel Hill.
The company plans to use the loan to finalize its business plan and prepare to seek financial backing from investors and federal grants. Until now, Dr. Egan's research has been supported by the National Institutes of Health, the Cystic Fibrosis Foundation, and the UNC Lung Transplant Research Fund.
Dr. Egan is working to develop therapies that might thwart inflammation and related damage (ischemia reperfusion injury) that occurs as blood flow is restored to tissues after a period of restricted blood supply. The compounds he is developing might keep naturally occurring immune-system proteins from contributing to IRI, reducing tissue damage after organ transplants. The research also could be useful in treatment of patients who have had heart surgery, strokes and heart attacks.

Thirty-two new cardiothoracic surgery resident physicians from across the nation attended the second annual Thoracic Surgery Resident Boot Camp July 31-Aug. 2 at the University of North Carolina at Chapel Hill. During 2½ days of intensive simulator-based training, the incoming residents learned and practiced basic cardiothoracic operating skills that will help them as they begin their residencies. More than 40 medical educators assisted with training on Cardiopulmonary Bypass Skills, Large/Small Vessel Anastomosis, Bronchoscopy/Mediastinoscopy, Open Lobectomy and Orientation to Aortic Valve Surgery.
The training was directed by Dr. Richard Feins of the Division of Cardiothoracic Surgery at UNC-Chapel Hill, Dr. James Fann of Stanford University and Dr. George Hicks of the University of Rochester, and was held at UNC's William and Ida Friday Center for Continuing Education in Chapel Hill. It was sponsored by the Thoracic Surgery Directors Association under a grant from the Joint Council on Thoracic Surgery Education, Inc. with support from these companies: CryoLife, Ethicon Endo-Surgery, Immersion Medical, Karl Storz Endoscopy, Medtronic, Olympus America, Inc., Teleflex Medical, Scanlan International, Sorin Group and St. Jude Medical.

In its July 2009 issue, American Journal of Physiology - Lung Cellular and Molecular Physiology published a paper, "Novel critical role of toll-like receptor 4 in lung ischemia-reperfusion injury and edema," from the lab of Thomas M. Egan, M.D., M.Sc., of the UNC Division of Cardiothoracic Surgery.
The manuscript adds to the growing body of evidence that the innate immune system contributes to non-infectious lung injury and proposes a completely new role for toll-like receptor 4 (TLR4) – regulation of acute microvascular endothelial cell permeability. Because of phenotypic similarity to many other types of acute lung injury, the Egan lab's findings have far-reaching implications. The research provides evidence that functional TLR4 on pulmonary parenchymal cells is responsible for very early and profound pulmonary edema following lung ischemia and reperfusion.
Dr. Egan’s research has focused for many years on lung ischemia-reperfusion injury (IRI), particularly as it relates to the possibility of lung retrieval after an interval of warm ischemia for possible transplant from cadavers, or non-heart-beating donors (NHBDs). If this became widely practical, it could eliminate the critical shortage of lungs for transplant.
The first author of the article, Giorgio Zanotti, MD, was a visiting research scholar in Dr. Egan's lab from the University of Pavia, Italy. He is now a surgery resident at Duke University. The other authors were Monica Casiraghi, MD; John B. Abano, MD; Jason Tatreau, BS (now a UNC medical student); Mayura Sevala, PhD; Hilary Berlin, BS; Susan Smyth, MD, PhD; William Funkhouser, MD; Keith Burridge, PhD; Scott Randell, PhD; and Dr. Egan.

In its Spring 2009 issue, the UNC Medical Bulletin traces the development of the heart and lung transplantation programs at UNC Hospitals. Dr. Michael Mill and Dr. Thomas Egan, both still on the faculty at UNC, started the programs after they were recruited by Dr. Benson Wilcox in 1988 and 1989, respectively. Today, UNC has six transplant surgeons; the transplant program includes a skilled team of transplant coordinators, nurses, perfusionists, anesthesiologists, surgeon's assistants, cardiologists, pulmonologists and pathologists.

The elderly are at high risk of acute coronary syndrome (ACS) but receive less cardiac medication and invasive care than other groups. Two factors may explain this: limited data from randomized clinical trials and uncertainty about benefit and risk with advancing age.
In two articles published recently in the journal Clinical Geriatrics, Dr. Brett Sheridan (right) and colleagues in the UNC School of Public Health, UNC Division of Cardiology, and Sheps Center for Health Services Research reviewed the use of therapies for ACS and the challenges of diagnosing and treating ACS in the elderly. They also examined outcomes results of invasive therapies (percutaneous coronary intervention and coronary artery bypass grafting).
Given the benefits observed in recent trials, age alone should not prevent consideration of invasive treatment of ACS in the elderly, but rather should intensify it, the group concluded.
The research was supported by an NIH R01 grant (Acute coronary syndrome outcomes in Medicare patients) on which Dr. Sheridan is co-principal investigator.

In a recent interview on NBC 17 TV, Benjamin E. Haithcock, MD, a UNC cardiothoracic surgeon, discusssed disparities in treatment of lung cancer. He discussed the same topic at a Lung Cancer Awareness Symposium at UNC's Lineberger Cancer Research Center on Nov. 17.
Glenda Frazier, 40, came to UNC from Fort Bragg after a doctor found a spot on her left lung. Dr. Haithcock biopsied the lung, discovered cancer, and then removed part of Frazier's lung using minimally invasive surgery.
Frazier was lucky because of the early diagnosis, but also because she got the right treatment.
Haithcock says she's an exception. He believes too many people, especially African Americans, don't try to seek specialized care or learn about treatment options that could save their lives. He says patients should always talk to their doctors about their options before agreeing to treatment.

Knowing Options May Prevent Deaths From Lung Cancer

At just 40 years old and an avid runner, Glenda Frazier hardly fits the picture of a lung cancer patient.
But last spring, a spot on her lung brought her from her home at Fort Bragg to see a doctor at UNC's cancer center.
"He said, ‘We'll go in, I'll biopsy it while you're asleep’... amazing!" said Frazier. " ‘If it's cancerous, we'll go ahead and take it out and remove it.’ "
Thoracic surgeon Dr. Benjamin Haithcock confirmed it was cancer and did a minimally invasive procedure to remove the lower lobe of Frazier’s left lung.
Frazier didn't have any follow-up chemotherapy or radiation. She was lucky because she was diagnosed early, but also because she got the right treatment. Haithcock says she's an exception to the rule. He believes too many people, especially African Americans, don't try to seek specialized care or learn about treatment options that could save their lives.
"I think there is a reluctance to have an operation, I think there is a reluctance to see any kind of surgeon," said Haithcock. "And I think there is still that reluctance, especially in elderly African Americans, of just going to a physician."
Haithcock says more blacks die within five years of diagnosis than whites, but with proper treatment, whether it's medicine or surgery, the survival rate is the same. He says patients should ask questions of their doctors and get more information before any kind of treatment.
Glenda Frazier is living proof.
"Do your research, talk to your doctors, talk to a specialist, not just some general person, and also talk to your friends," said Frazier. "Don't settle for no."
