Abstract
AbstractBackgroundThe influencing factors, especially time to treatment (TTT), for T1b/T2 gallbladder cancer (GBC) patients remain unknown. We aimed to identify the influencing factors on survival and surgical approaches selection for T1b/T2 GBC.MethodsWe retrospectively screened GBC patients between January 2011 and August 2018 from our hospital. Clinical variables, including patient characteristics, TTT, overall survival (OS), disease‐free survival (DFS), surgery‐related outcomes, and surgical approaches were collected.ResultsA total of 114 T1b/T2 GBC patients who underwent radical resection were included. Based on the median TTT of 7.5 days, the study cohort was divided into short TTT group (TTT ≤7 days, n = 57) and long TTT group (TTT >7 days, n = 57). Referrals were identified as the primary factor prolonging TTT (p < 0.001). There was no significance in OS (p = 0.790), DFS (p = 0.580), and surgery‐related outcomes (all p > 0.05) between both groups. Decreased referrals (p = 0.005), fewer positive lymph nodes (LNs; p = 0.004), and well tumor differentiation (p = 0.004) were all associated with better OS, while fewer positive LNs (p = 0.049) were associated with better DFS. Subgroup analyses revealed no significant difference in survival between patients undergoing laparoscopic or open approach in different TTT groups (all p > 0.05). And secondary subgroup analyses found no significance in survival and surgery‐related outcomes between different TTT groups of incidental GBC patients (all p > 0.05).ConclusionsPositive LNs and tumor differentiation were prognostic factors for T1b/T2 GBC survival. Referrals associating with poor OS would delay TTT, while the prolonged TTT would not impact survival, surgery‐related outcomes, and surgical approaches decisions in T1b/T2 GBC patients.
