Abstract Background tumor recurrence after NSCLC surgical resection is the most common cause of treatment failure that sharply reduces the patient’s life expectancy. The optimal treatment strategy for loco-regional recurrences developing after surgical resection in patients with non–small-cell lung cancer (NSCLC) is not established yet. This report aims to describe the pattern of relapse, PFS, and OS in patients treated with radio-chemotherapy and durvalumab for loco-regional relapse after surgery. Methods  We conducted a multicenter, retrospective study including subjects who underwent surgical resection for NSCLC and were treated with Pacific protocol after loco-regional relapse. Results Twenty-four patients met the inclusion criteria. At the time of diagnosis mean age was 65 years (range 47–78), the majority being male (58.3%). The 12-month progression-free survival rate was 68.7%, the 18-month progression-free survival rate was 45.8%, and the 24-month progression-free survival rate was 34.3%. There were three deaths: the 12-month survival rate was 91%, and the 18-month survival rate was 82.8%. Conclusions In this article, we propose a treatment strategy that might prolong post recurrence survival in patients with good performance status experiencing loco-regional relapse after surgery.
