However,controversies concerns exist regarding a variety of factors including the safety,feasibility, efficacy, and cost-effectiveness of robotic surgery. To promote the development of robotic hepatectomy, this study aimed to evaluate the current status of robotic hepatectomy and provide sixty experts' consensus and recommendations to promote its development. Based on the World Health Organization Handbook for Guideline Development, a Consensus Steering Group and a Consensus Development Group were established to determine the topics, prepare evidence-based documents, and generate recommendations. The GRADE Grid method and Delphi vote were used to formulate the recommendations. A total of 22 topics were prepared analyzed and widely discussed during the 4 meetings. Based on the published articles and expert panel opinion, 7 recommendations were generated by the GRADE method using an evidence-based method, which focused on the safety, feasibility, indication,techniques and cost-effectiveness of hepatectomy. Given that the current evidences were low to very low as evaluated by the GRADE method, further randomized-controlled trials are needed in the future to validate these recommendations.展开更多

Aim: To demonstrate that chronomodulated HAI triplet chemotherapy according to OPTILIV protocol is well tolerated and displayed high antitumor activity in this heavily-pretreated patient. Case Presentation: A 54 years old patient from Russia was treated for a tumor in the ascending colon presented with 13 hepatic metastases ranging from 0.3 to 2.7 cm in diameter. He underwent a laparoscopic right hemicolectomy, 12 cycles of FOLFIRINOX combined to bevacizumab for the last 5 cycles, resulting in a partial response according to CT scan. It was decided to perform a two-stage hepatectomy at Paul Brousse hospital: left partial hepatectomy allowed the excision of 9 lesions. Radio frequency ablation was performed in 2 nodular lesions. Afterwards, the patient received 5 cycles of chronomodulated triplet chemotherapy into the hepatic artery, according to the OPTILIV protocol design, yet without cetuximab, because of the KRAS mutation in the liver metastases, with a partial re-sponse. The patient could then undergo the second stage of the planned right hepatectomy, which turned out to be an R0 resection followed by receiving three courses of chronomodulated HAIC. Disease progression was documented after 3 months. Chronomodulated FOLFIRI chemotherapy was re-started intravenously, in combination with Aflibercept and it was associated with further disease progression. The genetic analysis of our patient’s cancer revealed a high level of MSI. The patient was included in the Phase 2 CheckMate-142 trial and received nivolumab 3 mg/kg every 2 weeks within 3 months. Treatment was discontinued due to ineffectiveness. Then the patient underwent radiotherapy geared towards reduction of pain. Afterwards, the patient died from the disease progression 2 years after the beginning of treatment. Conclusion: In this article, the authors report a clinical case with chronomodulated HAIC as rescue therapy in a heavily pretreated patient with metastatic colorectal cancer, allowing to achieve an objective response despite prior progression on FOLFIRINOX (the same triplet chemo by IV route). This strategy permitted to overcome drug resistance and to perform further complete resection of the liver me-tastases with prolonged patient survival. Thus, chronomodulated HAI is useful in patients with liver metastases from colorectal cancer and de-serves to be further assessed prospectively in clinical trials chemotherapy.展开更多
