肿瘤出芽和 TIL（肿瘤浸润淋巴细胞）与胆囊癌临床病理参数的相关性

Gallbladder carcinoma (GBC) poses significant challenges in oncology due to its aggressive nature and limited treatment options. The lack of effective biomarkers for early detection and prognosis exacerbates the prognosis for GBC patients. Tumor budding (TB) and tumor infiltrating lymphocytes (TILs) have emerged as potential prognostic indicators in various cancers, reflecting tumor-host immune interactions and tumor aggressiveness. The study of TB and TILs in GBC is particularly important due to the limited literature available.

This retrospective observational study aimed to evaluate the association of TB and TILs with clinicopathological parameters in GBC patients. Clinicopathological data were collected from patients with histologically confirmed GBC who underwent surgical resection. The sections were evaluated for TB and TILs using standardized methods. Statistical analysis was performed to assess associations between these parameters and clinicopathological variables.

Tumor stage and grade showed significant associations with TB and TILs, indicating their potential as prognostic markers. High TB correlated with advanced tumor stage and higher grade, while high TIL infiltration was associated with early tumor stage and lower grade. Additionally, TILs exhibited a significant association with lymphovascular invasion. Interestingly, an inverse association was observed between TB and TILs, highlighting the dynamic interplay between tumor aggressiveness and host immune response.

TB and TILs hold prognostic significance in GBC, offering insights into its pathogenesis and potential therapeutic targets. Future research exploring the mechanistic underpinnings of tumor-host immune interactions in GBC is crucial for translating these findings into clinical applications and improving outcomes for patients.
