BACKGROUND Patients with desmoplastic (angiogenic) histopathological growth pattern (HGP) colorectal liver metastases (CLM) might derive more benefit from bevacizumab-based chemotherapy than those with replacement (non-angiogenic) HGP. This study investigated the association of HGP with the immune phenotype (IP) and clinical outcome after liver resection. METHODS CLM of patients treated with perioperative bevacizumab-based chemotherapy and liver resection were investigated. Association of HGP and IP with response, recurrence-free survival (RFS) and overall survival (OS) was investigated. RESULTS One hundred and eighteen patients (M/F 66/52, median age 62.3 (31.0-80.4) years, median follow-up 32.2 (5.0-92.7) months) were enrolled. The inflamed IP was associated with the desmoplastic HGP. The desmoplastic HGP was associated with better radiological and histological response compared to the replacement HGP, respectively. The replacement HGP was associated with shorter RFS (8.7 versus 16.3 months, HR 2.60, P = 0.001) and OS (36.6 months versus not reached, HR 2.32, P = 0.027), respectively. The non-inflamed IP was associated with shorter RFS (10.8 versus 16.5 months, HR 1.85, P = 0.029). The HGP but not the IP remained significant in multivariable analysis for RFS. CONCLUSIONS The desmoplastic HGP is associated with the inflamed IP and HGP may be a potential biomarker for adjuvant treatment that includes targeting the immune contexture.

结直肠肝转移患者的免疫表型和组织病理学生长模式。

背景 具有促纤维增生(血管生成)组织病理学生长模式(HGP)结直肠肝转移(CLM)的患者可能比替代(非血管生成)HGP 患者从基于贝伐单抗的化疗中获益更多。本研究调查了 HGP 与肝切除术后免疫表型 (IP) 和临床结果的关系。方法 对围手术期以贝伐单抗为基础的化疗和肝切除术治疗的患者的 CLM 进行调查。研究了 HGP 和 IP 与反应、无复发生存期 (RFS) 和总生存期 (OS) 的关联。结果 118 名患者(男/女 66/52,中位年龄 62.3(31.0-80.4)岁,中位随访 32.2(5.0-92.7)个月)入组。发炎的 IP 与促纤维增生性 HGP 相关。与替代 HGP 相比,促纤维增生 HGP 分别与更好的放射学和组织学反应相关。替代 HGP 分别与较短的 RFS(8.7 与 16.3 个月,HR 2.60,P = 0.001)和 OS(36.6 个月与未达到,HR 2.32,P = 0.027)相关。非炎症性 IP 与较短的 RFS 相关(10.8 个月对 16.5 个月,HR 1.85,P = 0.029)。HGP 而不是 IP 在 RFS 的多变量分析中仍然很重要。结论 促纤维增生性 HGP 与发炎的 IP 相关,HGP 可能是包括靶向免疫环境在内的辅助治疗的潜在生物标志物。6 个月与未达到,HR 2.32,P = 0.027),分别。非炎症性 IP 与较短的 RFS 相关(10.8 个月对 16.5 个月,HR 1.85,P = 0.029)。HGP 而不是 IP 在 RFS 的多变量分析中仍然很重要。结论 促纤维增生性 HGP 与发炎的 IP 相关,HGP 可能是包括靶向免疫环境在内的辅助治疗的潜在生物标志物。6 个月与未达到,HR 2.32,P = 0.027),分别。非炎症性 IP 与较短的 RFS 相关(10.8 个月对 16.5 个月,HR 1.85,P = 0.029)。HGP 而不是 IP 在 RFS 的多变量分析中仍然很重要。结论 促纤维增生性 HGP 与发炎的 IP 相关,HGP 可能是包括靶向免疫环境在内的辅助治疗的潜在生物标志物。
