The post-transplant survival measure is one-year survival after transplantation of the lungs. Factors used to predict it include FVC, ventilator use, age, creatinine, NYHA class and diagnosis. [3] It is used for calculation of transplant benefit by subtracting another variable called waitlist urgency measure from it. The final lung allocation ...
In 2003, Yao et al. reported experience at the University of California San Francisco five-year post-transplantation survival of 75% in patients with tumors as large as 6.5 cm, or up to three lesions each less than 4.5 cm with cumulative tumor burden ≤8 cm. [4] Additional studies using these so-called "UCSF criteria" have shown favorable post ...
