Memphis, TN, March 09, 2023 (GLOBE NEWSWIRE) -- Memphis-based Baptist Cancer Center published a JAMA Network Open article proving the effectiveness of incidental lung nodule, or tumor, programs in detecting lung cancer early.
The cohort study, titled “Evaluation of Lung Cancer Risk Among Persons Undergoing Screening or Guideline-Concordant Monitoring of Lung Nodules in the Mississippi Delta,” compared the effectiveness of scheduled lung screenings against incidental diagnostic scans (taken during emergencies or other unrelated situations) in detecting cancer early. Dr. Raymond Osarogiagbon, chief scientist for Baptist Memorial Health Care/director of the Multidisciplinary Thoracic Oncology Program and the Thoracic Oncology Research Group for Baptist Cancer Center, was principal investigator of the study.
“This is exciting news for the lung cancer community,” said Dr. Osarogiagbon. “This study establishes the importance of both incidental scans and scheduled screenings in detecting cancer early. Typically, a large number of people with incidentally detected lung nodules would not qualify for lung cancer screening under current eligibility guidelines. With this new dual approach, we can save more lives. ”
This cohort study, in which participants share a common characteristic, was conducted from Jan. 1, 2015, to Dec. 31, 2021, and included 6,684 participants in a low-dose computed tomography screening group and 12,645 participants in a lung nodule program. Those in the lung nodule program had significantly greater incidence of lung cancer diagnosis within two years. These findings suggest that lung nodule program participants, regardless of smoking history, had a substantial risk for lung cancer.
“One thing our research shows is that screening alone can only go so far in finding more lung cancers early, so it is important to have a complementary lung nodule program,” said Dr. Osarogiagbon. “Through this work, we are now primed to explore how artificial intelligence and biomarker research can improve the effectiveness of early lung cancer detection in Mid-South communities.”
The lung nodule program also provided access to early detection for a higher proportion of Black persons and those at greatest risk for lung cancer, such as the less educated, rural dwellers and the socioeconomically disadvantaged.
Lung cancer is often diagnosed at a late stage because people do not have symptoms until the disease is advanced. While it has been shown lung cancer screening saves lives, most people aren’t aware of the availability of lung cancer screening and many of the people who are at risk would not qualify for screening under current guidelines. However, guideline-concordant management of incidentally detected lung nodules would provide another route to early detection of lung cancer.
“We are so proud of our team of doctors, scientists and researchers for these leading-edge efforts to find new ways of diagnosing lung cancer early,” said Ann Bishop, system administrator of oncology for Baptist Cancer Center. “This research proves our methods are effective, and our efforts are unmatched in the fight against lung cancer and disparities.”
In 2021, Baptist Cancer Center announced a multifaceted initiative called the Mid-South Miracle aimed at reducing lung cancer deaths in the Mid-South 25% by 2030. The initiative comprises seven components that will address prevention, diagnosis and treatment of lung cancer through smoking cessation, low-dose CT screening, algorithmic management of incidentally detected lung nodules, multidisciplinary decision-making and care, high-quality surgical care, high-quality pathologic evaluation, including biomarker testing, and expanded access to innovative treatment through clinical trials.
Baptist Memorial Health Care Foundation awarded a $1 million grant to Baptist Cancer Center in August 2020 to fund the incidental nodule research project.

JAMA, published continuously since 1883, is an international peer-reviewed general medical journal. JAMA is a member of the JAMA Network, a consortium of peer-reviewed, general medical and specialty publications. JAMA is the most widely circulated general medical journal in the world, with more than 290,000 recipients of the print journal, more than 1.6 million recipients of electronic tables of contents and alerts, and over 34 million annual visits to the journal's website. JAMA's reach includes a growing social media presence and vast international news media exposure. JAMA's acceptance rate is 11% of the more than 9,400 annual submissions and 4% of the more than 5,200 research manuscripts received.
Baptist Cancer Center provides world-class cancer care close to home throughout Baptist Memorial Health Care’s tristate service area of Arkansas, Mississippi and Tennessee. The center takes an interdisciplinary approach to patient care and offers treatment, research, support services, community education and the area's first genetic counseling and testing program for cancer. In addition, BCC has the Mid-South's first adult myelosuppression unit, which provides specialized care for patients who have received chemotherapy that interferes with blood cell production or stops bone marrow activity. In 2019, BCC was awarded a second $9 million research grant from the National Cancer Institute to continue building its clinical research infrastructure to expand lifesaving, leading-edge treatment across the Mid-South, including overcoming disparities in cancer care under the Minority/Underserved NCI Community Oncology Research Program, known as NCORP.
