For advanced gastric cancer (AGC), neoadjuvant chemotherapy (NAC) can reduce its stage, increase the rate of radical resection, improve response to treatment, reduce the risk of local recurrence and improve survival rate. Regional arterial infusion chemotherapy (RAIC) is a form of NAC that involves directly injecting chemotherapeutic drugs into the tumor site through the tumor-feeding artery. RAIC increases the local drug concentration around the tumor, thereby improving the therapeutic responses and reducing the adverse effects of the drugs. In recent years, RAIC has attracted increasing attention. This article summarizes the basic principles, procedure, chemotherapy regimens, adverse drug reactions and complications, clinical applications and response evaluation of RAIC in the treatment of AGC.展开更多

We fashioned a multilayer cylindrical implant termed STID100 that released doxorubicin for 3 weeks in an orthotopic 4T1 breast cancer model in Balb/C mice. This implant starts as a thin doxorubicin-embedded PLGA membrane, and is then rolled into a cylinder containing an air gap between the membrane layers. Its controlled sustained release delivered 2× the amount of the intravenous (IV) equivalent of doxorubicin, inhibited the primary tumor, and prevented lung metastasis. Importantly it did not cause weight loss, splenomegaly, or cardiac toxicity vs systemically administrated doxorubicin. This favorable safety profile is further substantiated by the finding of no detectable plasma doxorubicin in multiple time points during the 3-week period, and low tumor doxorubicin concentration. The implant system delivered to the specification of an ideal pharmacological paradigm might offer a better coverage of the local tumor, significantly preventing metastatic spread with less drug toxicity to many vital organs, compared to the traditional pharmacology of IV route. The profile of STID made it an attractive therapeutic alternative in metastatic tumor prevention, pain management and many other diverse clinical scenarios.展开更多

Methods:A total of 90 patients with primary gastric cancer who received treatment in Tianyou Hospital Affiliated to Wuhan University of Science & Technology between January 2014 and May 2016 were collected and divided into control group and observation group according to the random number table method, 45 cases in each group. The control group of patients received routine systemic intravenous chemotherapy + surgical treatment, and the observation group of patients received systemic intravenous chemotherapy combined with local arterial perfusion chemoembolization + surgical treatment. Levels of tumor markers and angiogenesis factors in serum as well as the expression of oncogenes and tumor suppressor genes in gastric cancer tissue were compared between the two groups of patients before and after chemotherapy.Results:Before chemotherapy, the levels of tumor markers and angiogenesis factors in serum as well as the expression of oncogenes and tumor suppressor genes in gastric cancer tissue were not significantly different between the two groups of patients;after chemotherapy, serum CEA, CA724, CA242, AFP, VEGF, Ang-2, COX2 and PD-ECGF levels of observation group were lower than those of control group, andiASPP, p130Cas, ERBB2 and C-myc mRNA expression in gastric cancer tissue were lower than those of control group while GKN1, p16, PTEN, TSPYL5 and merlin mRNA expression in gastric cancer tissue were higher than those of control group.Conclusions: Preoperative systemic intravenous chemotherapy combined with regional arterial perfusion chemoembolization can effectively reduce the malignancy of locally advanced gastric cancer and provide favorable conditions for the operation.展开更多

Many efforts have been made to improve the survival in patients with peritoneal metastasis. Hyperthermic intraperitoneal chemotherapy remains a widely accepted strategy in the treatment of peritoneal dissemination. Several phase Ⅱ-Ⅲ studies confirmed that the combined cytoreducitve surgery and hyperthermic intraperitoneal chemotherapy resulted in longer survival in patients with peritoneal carcinomatosis. In addition,proper selection and effective regional treatment in patients with high risk of peritoneal recurrence after resection will further improve prognosis in local advanced gastric cancer patients.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
