Background And Objectives:
Adoptive T-cell therapies (ACTs) using expansion of tumor-infiltrating lymphocyte (TIL) populations are of great interest for advanced malignancies, with promising response rates in trial settings. However, postoperative outcomes following pulmonary TIL harvest have not been widely documented, and surgeons may be hesitant to operate in the setting of widespread disease.
Methods:
Patients who underwent pulmonary TIL harvest were identified, and postoperative outcomes were studied, including pulmonary, cardiovascular, infectious, and wound complications.
Results:
83 patients met inclusion criteria. Pulmonary TIL harvest was undertaken primarily via a thoracoscopy with a median operative blood loss and duration of 30 ml and 65 min, respectively. The median length of stay was 2 days. Postoperative events were rare, occurring in only five (6%) patients, including two discharged with a chest tube, one discharged with oxygen, one episode of urinary retention, and one blood transfusion. No reoperations occurred. The median time from TIL harvest to ACT infusion was 37 days.
Conclusions:
Pulmonary TIL harvest is safe and feasible, without major postoperative events in our cohort. All patients were able to receive intended ACT infusion without delays. Therefore, thoracic surgeons should actively participate in ongoing ACT trials and aggressively seek to enroll patients on these protocols.
