      • Abstract

      Background:
      The effect of surgical waiting time on prognosis in patients with lung cancer remains unknown. The purpose of this study is to examine the impact of surgical waiting time on outcome in patients with lung cancer.

      Method:
      We retrospectively reviewed all patients who underwent complete surgical resection in a single center between January 2006 and May 2016. Waiting time is defined as the interval between the date of initial visit to the department of respiratory medicine or thoracic surgery and the date of surgery. The patients were divided into two groups based on surgical waiting time: group A (n=160), 0-37 days; group B (n=150), 38 days or longer. Patients who had received neoadjuvant therapy, history of previous primary lung cancer and waiting time greater than 6 months were excluded.

      Result:
      310 patients met inclusion criteria (65.8% men; median age: 67yrs; c-stage I / II / III 249 / 41 / 20, p-stage I / II / III 212 / 47 / 51, median waiting time: 37 days). Waiting time tends to be shorter as c-stage of disease (I / II / III 38 / 35 / 31.5 days) becomes more advanced. Bronchoscopy or CT guided biopsy before surgery was performed in the group A / B, 160 / 150 patients, respectively. Charlson Comorbidity Index (CCI) (0 / 1 / 2 / 3 / 4 / 5 / 6 / 7) was in the group A: B; 97 / 20 / 33 / 7 / 1 / 0 / 1 / 1: 72 / 27 / 37 / 11 / 2 / 0 / 0 / 1, respectively; group B was significantly associated with higher comorbidity rate. The 5-year RFP in the group A / B was 60.7 / 67.6% (p=0.19) (c-stage I / II / III 70.8 / 31.3 / 21.4%, 68.7 / 66.6 / 50%(p=0.92/0.32/0.3)), respectively. The 5-year OS in the group A / B was 75.6 / 82.6% (p=0.3) (c-stage I / II / III 83.3 / 68 / 21%, 85.7 / 79.3 / 0%(p=0.77 / 0.82 / 0.62)), respectively.

      Conclusion:
      Surgical waiting time from initial visit to operative intervention does not adversely affect recurrence and survival.
