目的

对比新辅助化疗与新辅助化疗联合免疫治疗(nICT)后胃上部癌(UGC)实施近端胃切除术(PG)的临床疗效。

方法

回顾性收集2017年1月至2025年3月接受新辅助治疗后完成手术的UGC患者257例,按治疗方式不同分为单纯化疗组(n=114,行新辅助化疗)和联合免疫组(n=143,行新辅助化疗联合PD-1抑制剂)。采用SPSS 27.0软件进行数据分析。符合正态分布的计量资料以(±s)表示,采用独立样本t检验;不符合正态分布的计量资料以[M(Q1Q3)]表示,采用Mann-Whitney U检验;计数资料以[例(%)]表示,采用χ2检验;等级资料行秩和检验。P<0.05为差异具有统计学意义。

结果

两组患者清扫淋巴结数目、肿瘤退缩分级(TRG)、脉管浸润、神经侵犯、手术时间、术中预估出血量、术后住院时间、手术并发症及≥3级并发症发生率对比,差异无统计学意义(P>0.05);联合免疫组患者病理完全缓解(pCR)率、主要病理缓解率和实施PG比例均高于新辅助化疗组;而淋巴结转移数目和实施开腹手术比例低于新辅助化疗组(P<0.05)。多因素回归分析显示,身体质量指数(BMI)>24.0kg/m2、新辅助化疗联合免疫治疗和肿瘤最长径≤5cm是影响新辅助治疗后选择PG的独立影响因素(P<0.05)。

结论

局部进展期UGC经nICT后肿瘤原发灶退缩及区域淋巴结控制效果更好,且未增加手术风险。

Objective

To compare the clinical efficacy of proximal gastrectomy (PG) for upper gastric cancer (UGC) after neoadjuvant chemotherapy alone versus neoadjuvant chemotherapy combined with immunotherapy (nICT).

Methods

A retrospective collection was conducted on 257 UGC patients who underwent neoadjuvant therapy followed by surgery from January 2017 to March 2025. They were divided into two groups based on treatment modalities: the chemotherapy-alone group (n=114, receiving neoadjuvant chemotherapy) and the combined immunotherapy group (n=143, receiving neoadjuvant chemotherapy combined with PD-1 inhibitors). Data analysis was performed using SPSS 27.0 software. Measurement data with normal distribution were expressed as (±s) and analyzed by independent samples t test; measurement data with non-normal distribution were expressed as [M(Q1, Q3)] and analyzed by Mann-Whitney U test; counting data were expressed as [cases (%)] and analyzed by χ2 test; ranked data were analyzed by Rank Sum test. P<0.05 was considered statistically significant.

Results

There were no statistically significant differences between the two groups in terms of the number of dissected lymph nodes, tumor regression grade (TRG), vascular invasion, perineural invasion, operation time, estimated intraoperative blood loss, postoperative hospital stay, surgical complications, or the incidence of grade ≥3 complications (P>0.05). The combined immunotherapy group had higher rates of pathological complete response (pCR), major pathological response, and PG implementation; in contrast, it had lower rates of lymph node metastasis and open surgery implementation compared with the neoadjuvant chemotherapy group (P<0.05). Multivariate regression analysis showed that body mass index (BMI) >24.0 kg/m2, neoadjuvant immunotherapy combined with chemotherapy regimen, and maximum tumor diameter ≤5 cm were independent influencing factors for choosing PG after neoadjuvant therapy (P<0.05).

Conclusion

For locally advanced UGC, nICT achieves better tumor primary lesion regression and regional lymph node control without increasing surgical risks.
