A study published July 8 in JAMA indicates that lung transplantation significantly improves survival outcomes for select patients with stage 4 lung cancer. According to researchers at Northwestern Medicine, patients receiving a transplant experienced a 100% one-year survival rate, compared to a 41% survival rate among those treated with medical therapy alone.
How do survival rates compare for stage 4 lung cancer patients?
The clinical data shows a sharp divergence in patient outcomes based on treatment path. Northwestern Medicine analyzed 98 patients with stage 4 lung cancer between September 2021 and June 2025. Of that cohort, 17 patients underwent a lung transplant, while 81 received only medical therapy due to logistical, financial, or geographic constraints. At the conclusion of the study period, all 17 transplant recipients remained alive, whereas fewer than half of the patients who received medical therapy survived.
Patients without cancer who received a lung transplant in the same study cohort had an 88% one-year posttransplant survival rate, demonstrating that transplant success for specific cancer patients can be comparable to non-cancer outcomes.
What is the role of the DREAM registry?
The findings are linked to the Double Lung Transplant Registry for Lung-Limited Malignancies, commonly referred to as the DREAM program. Northwestern Medicine established this registry to evaluate the feasibility of lung transplantation for patients with organ-confined, treatment-resistant lung cancer. The primary goal is to provide a viable treatment option for patients who face a high risk of death from respiratory failure, moving beyond traditional palliative or medical-only approaches.
Future trends in transplant oncology
However, the 100% one-year survival rate observed in the Northwestern study provides a new baseline for medical discourse regarding transplant candidacy.

Frequently Asked Questions
Who is eligible for the DREAM program?
The program focuses on patients with organ-confined, treatment-resistant lung cancer who are at risk of dying from respiratory failure, according to Northwestern Medicine.
Why did some patients in the study not receive a transplant?
The study noted that 81 patients received medical therapy alone because of logistical, financial, or geographic factors rather than strictly clinical contraindications.
Is lung transplant now a standard treatment for stage 4 lung cancer?
The study indicates that lung transplant can extend survival for some patients, but it is currently part of specialized research and registry programs like the DREAM registry rather than universal standard practice.
