Taiwan Doctors Reassure Public on Lung Cancer Screening Effectiveness Amid Surgery Concerns

Taiwan's push for low-dose computed tomography (LDCT) lung cancer screenings is facing public skepticism over concerns of unnecessary surgeries. However, doctors at Taichung Tzu Chi Hospital are using national health insurance data to counter these doubts, asserting that the screening policy is precise and effective.

The screening policy is indeed precise and effective, not an overdiagnosis as claimed by some.

Dr. Ke Chih-lin, a thoracic surgeon, presented statistics showing that the total number of lung resection surgeries in Taiwan has remained stable over the past three years, with only minor fluctuations. He highlighted that lung lobe resections have also stayed consistent, debunking fears of a surge in invasive procedures. Instead, there's a notable increase in lung segment resections, a less invasive approach that preserves more lung function, indicating a trend toward more refined surgical practices driven by early detection.

Early detection of lung cancer often has no symptoms; only regular screening and continuous follow-up are key to protecting family members.

A patient, Ms. Chen, shared her experience of discovering nodules on both lungs through a health check, despite having no family history of smoking or significant exposure to cooking fumes. Prompted by her doctor's reminder of family history risks, she urged her siblings to get screened. Her early detection and minimally invasive surgery allowed her to avoid chemotherapy and also led to the discovery of lung issues in two of her siblings. Sadly, her third sister passed away from late-stage lung adenocarcinoma years ago, reinforcing Ms. Chen's conviction that early, regular screening is crucial for safeguarding family health, as early-stage lung cancer often presents no symptoms.

Objective data shows that surgical patterns are developing in a healthy direction toward smaller, more refined procedures due to early detection of lesions.

Dr. Ke emphasized that Taiwan's data is compelling and should encourage public trust in public health policies. Before the widespread adoption of precise screening, 64% of lung cancer patients in Taiwan were diagnosed at intermediate or late stages. Following the implementation of LDCT screening, this figure has reversed, with over 70% now being diagnosed at the earliest stages. For non-smokers with a family history of lung cancer, regular screening can decrease the incidence of late-stage disease by 72% and reduce mortality by 67%, establishing an international benchmark in lung cancer prevention.
