THURSDAY, Dec. 8, 2022 (HealthDay News) -- There is a high cure rate for screen-detected lung cancers, according to a study presented at the annual meeting of the Radiological Society of North America, held from Nov. 27 to Dec. 1 in Chicago.
Claudia Henschke, Ph.D., M.D., from the Icahn School of Medicine at Mount Sinai in New York City, and colleagues estimated 20-year lung cancer-specific survival (LCS) among 87,416 participants enrolled in a prospective, international, multicenter study of low-dose computed tomography screening for lung cancer (I-ELCAP). The analysis included 1,285 I-ELCAP participants.
The researchers found that 20-year lung cancer-specific survival was 80 percent. Lung cancer-specific survival was 100 percent for participants with nonsolid consistency and part-solid consistency and 73 percent for participants with solid consistency. For clinical stage IA participants, lung cancer-specific survival was 86 percent, regardless of consistency. Lung cancer-specific survival was 92 percent for participants with pathologic stage IA lung cancer (≤10 mm in average diameter).
"What we present here is the 20-year follow-up on participants in our screening program that were diagnosed with lung cancer and subsequently treated," Henschke said in a statement. "The key finding is that even after this long a time interval they are not dying of their lung cancer."
