背景:化疗的进展增加了无法手术的晚期胃癌转换手术的临床经验。本报告描述了三名不可切除的胃癌伴多发性肝转移的患者。在所有三个病人中,nivolumab解决了肝转移,随后的转化手术获得了病理完全缓解.
方法:在病例1中,一名68岁的临床IVB期胃癌和多发性肝转移患者开始使用SOX联合nivolumab进行一线治疗。患者完成了13个周期;然而,由于不良事件,只有纳武单抗继续治疗3个周期.由于磁共振成像(MRI)观察到肝转移灶的大小显着减少,因此进行了远端胃切除术和部分肝切除术。在病例2中,一名72岁的临床IVB期胃癌和多发性肝转移患者开始使用SOX进行一线治疗。由于随后出现了新的肝转移瘤,患者转用雷莫珠单抗联合紫杉醇作为二线治疗.由于副作用,开始了nivolumab的三线治疗。MRI显示肝转移灶坏死,患者接受了近端胃切除术和部分肝切除术。在病例3中,一名51岁的临床IVB期胃癌患者伴有肝脏和主动脉旁淋巴结的多个转移,开始使用SOX加nivolumab进行一线治疗。患者完成了10个周期;然而,由于不良事件,只有纳武单抗继续治疗5个周期.计算机断层扫描显示主动脉旁淋巴结的大小明显减小,而MRI显示存在单一的肝转移。随后进行远端胃切除术和部分肝切除术。在这三种情况下,MRI显示存在肝转移;然而,病理检查无肿瘤细胞存活。
结论:我们在此介绍三例化疗,包括Nivolumab,在多个不可切除的肝转移患者中引起了反应,最终通过转换手术切除R0。尽管MRI显示肝转移,病理分析显示没有癌症,强调化疗的有益影响。
BACKGROUND: Advances in chemotherapy have increased clinical experience with conversion surgery for inoperable advanced gastric cancer. This report describes three patients with unresectable gastric cancer accompanied by multiple liver metastases. In all three patients, nivolumab resolved the liver metastases and subsequent conversion surgery achieved a pathological complete response.
METHODS: In
Case 1, a 68-year-old man with clinical Stage IVB gastric cancer and multiple liver metastases initiated first-line therapy with SOX plus nivolumab. The patient completed 13 cycles; however, only nivolumab was continued for 3 cycles because of adverse events. Distal gastrectomy and partial hepatic resection were performed because of a significant reduction in the size of the liver metastases as observed on magnetic resonance imaging (MRI). In
Case 2, a 72-year-old man with clinical Stage IVB gastric cancer and multiple liver metastases initiated first-line therapy with SOX. Because of the subsequent emergence of new liver metastases, the patient transitioned to ramucirumab plus paclitaxel as second-line therapy. Third-line therapy with nivolumab was initiated because of side effects. MRI revealed necrosis within the liver metastasis, and the patient underwent proximal gastrectomy and partial hepatectomy. In
Case 3, a 51-year-old woman with clinical Stage IVB gastric cancer accompanied by multiple metastases of the liver and para-aortic lymph nodes began first-line therapy with SOX plus nivolumab. The patient completed 10 cycles; however, only nivolumab was continued for 5 cycles because of adverse events. Computed tomography showed a significant decrease in the size of the para-aortic lymph nodes, while MRI indicated the presence of a singular liver metastasis. Distal gastrectomy and partial hepatic resection were subsequently performed. In all three cases, MRI revealed the presence of liver metastases; however, pathological examination showed no viable tumor cells.
CONCLUSIONS: We herein present three cases in which chemotherapy, including nivolumab, elicited a response in patients with multiple unresectable liver metastases, ultimately culminating in R0 resection through conversion surgery. Although MRI showed liver metastases, pathological analysis revealed no cancer, underscoring the beneficial impact of chemotherapy.
