Maxwell Oluwole Akanbi, MD, PhD, on Lung Cancer: The Effect of Screening on the Incidence of Advanced Disease
2022 ASCO Annual Meeting
Maxwell Oluwole Akanbi, MD, PhD, of McLaren Regional Medical Center, discusses the study he conducted, using the SEER database, to evaluate the impact of lung cancer screening recommendations on low-dose CT scanning. The data suggest that guidelines from the U.S. Preventive Services Task Force led to a more rapid decline in the incidence of advanced disease in the United States, especially among minority populations (Abstract 10506).

Lung cancer is the leading cause of cancer mortality in the US, and this is because most patients with lung cancer are diagnosed at advanced stages of the disease. Trying to make patients present earlier has been an elusive challenge, until in 2011, when results of the National Lung Cancer Trial were reported. This study showed that low-dose CT scan could improve survival in patients with lung cancer by making earlier diagnosis. Although this has been shown in clinical trials, the government has ruled out lung cancer screening in the general population without also actually knowing whether it is efficacious in the general population.
Our study was to evaluate the effectiveness of lung cancer screening in the US general population. You will use the SEER database, we analyzed data of patient diagnosed with lung cancer from 2004 to 2018. Our goal was to see if the incidence of advanced lung cancer reduced over this time. Our results showed that incidence of advanced lung cancer actually decreased in the US population following the rollout of lung cancer screening. This was particularly significant in minority populations. This is encouraging because there have been concerns that lung cancer screening may not be very effective in this population because they had limited access to screening facilities.
So, while this is encouraging, the work is not yet done. Our end goal is to make sure there's reduction in lung cancer mortality. There are still barriers between screening and mortality, so the next stage of our study will be to see whether this reduction in incidence of advanced lung cancer actually translate to reduction in lung cancer mortality.
Ann H. Partridge, MD, MPH, of Dana-Farber Cancer Institute, and Kevin Kalinsky, MD, of Winship Cancer Institute at Emory University, discuss phase II findings from the MAINTAIN trial, which showed a benefit in progression-free survival for patients with hormone receptor–positive/HER2-negative metastatic breast cancer when they switched to endocrine therapy and received ribociclib after disease progression on another CDK4/6 inhibitor (Abstract LBA1004).
Rainer Fietkau, MD, of Germany’s University Hospital Erlangen, discusses phase III findings of the CONKO-007 trial, which examined the role of sequential chemotherapy and chemoradiotherapy administered to patients with nonresectable locally advanced pancreatic cancer following standard-of-care chemotherapy (Abstract 4008).
Bradley J. Monk, MD, of the University of Arizona College of Medicine and Creighton University School of Medicine, discusses phase III findings from the ATHENA–MONO (GOG-3020/ENGOT-ov45) trial. It showed that rucaparib as first-line maintenance treatment, following first-line platinum-based chemotherapy, improved progression-free survival in patients with ovarian cancer, irrespective of homologous recombination deficiency status (Abstract LBA5500).
Sriram Yennu, MD, of The University of Texas MD Anderson Cancer Center, discusses the placebo response in patients with advanced cancer and cancer-related fatigue. His latest findings show that open-labeled placebo was efficacious in reducing cancer-related fatigue and improving quality of life in fatigued patients with advanced cancer at the end of 1 week. The improvement in fatigue was maintained for 4 weeks (Abstract 12006).
Timothy J. Whelan, MD, of McMaster University and Hamilton Health Sciences, discusses findings from the LUMINA study, which found that women aged 55 or older who had grade 1–2 T1N0 luminal A breast cancer following breast-conserving surgery and were treated with endocrine therapy alone had very low rates of local tumor recurrence at 5 years. These patients, the research suggests, may be able to forgo radiotherapy (Abstract LBA501).
