For most people, breathing is effortless and taken for granted. For patients with end-stage lung disease, however, every breath can be a struggle. Even walking a few steps may cause severe shortness of breath, and climbing stairs often requires frequent pauses. As lung function continues to decline, even oxygen therapy may no longer provide relief, leading to a significant deterioration in quality of life.
Dr. Guang-Tai Kuo, a thoracic surgeon at Shuang Ho Hospital and recently elected as Taiwan’s sixth member of the American Association for Thoracic Surgery (AATS), notes that for some patients, lung transplantation represents the final line of treatment—and a crucial opportunity to regain a normal life.
When Should Lung Transplantation Be Considered?
The concept of end-stage lung disease is somewhat comparable to end-stage renal disease. When kidney function fails, dialysis is required to sustain life; similarly, when lung function deteriorates, patients often rely on supplemental oxygen.
Some individuals can maintain basic daily activities with oxygen therapy. However, many experience progressive worsening despite continuous oxygen use. Their oxygen requirements increase over time—from a simple nasal cannula to non-invasive ventilation, and eventually, in severe cases, endotracheal intubation to sustain breathing.
Dr. Kuo explains that when patients already require oxygen and continue to experience declining quality of life—such as becoming breathless after minimal exertion or struggling with routine activities at home—lung transplantation should be discussed. Nevertheless, eligibility must be carefully evaluated by physicians, taking into account factors such as age and overall health condition.
The Reality of Waiting for a Suitable Lung
Even when patients meet the criteria for transplantation, the procedure cannot be performed immediately. In addition to the limited availability of donor organs, several conditions must be met.
First, blood type compatibility is essential. Second, the donor and recipient must have similar body sizes. Since the lungs must fit within the recipient’s chest cavity, a significant height discrepancy can affect surgical outcomes; generally, a height difference within approximately 10 cm is preferred.
Waiting time is another major challenge. In Taiwan, some patients may wait more than two years for a suitable organ. Therefore, medical teams often recommend early evaluation to avoid missing the optimal window as the disease rapidly progresses.
Lung Transplantation: A Life-Changing Procedure
Dr. Kuo recalls a particularly memorable case involving a female patient. Before her transplant, she suffered from persistent chest tightness and pain, and recurrent pneumothorax episodes that severely impaired her ability to breathe. She required oxygen support even during sleep, and as her lung function deteriorated, both her quality of life and survival were at risk.
Although she was registered on the transplant waiting list, a suitable donor was not immediately available. In the month prior to surgery, she required extracorporeal membrane oxygenation (ECMO) for life support. Fortunately, she eventually received a suitable donor lung. After a challenging 13-hour surgery, the transplant was successfully completed.
Now, more than two years later, her lung function remains stable. She has regained mobility and returned to work and daily life. As Dr. Kuo describes, she once could only sit at home and look out the window—today, her life has been completely transformed.
A Chance to Start Anew
Many patients with end-stage lung disease remain alive, but their daily lives are severely restricted by breathlessness, often confining them indoors. Dr. Kuo emphasizes that lung transplantation is not suitable for everyone, but patients are encouraged to discuss the option with their physicians.
With the support of multidisciplinary medical teams and organ donation systems, lung transplantation offers these patients—who struggle for every breath—a renewed chance to begin again.
