SOX combined with intraperitoneal perfusion of docetaxel compared with DOS regimen in the first-line therapy for advanced gastric cancer with malignant ascites: a prospective observation. Trials 2022; 23:211. [PMID: 35279214 PMCID: PMC8917651 DOI: 10.1186/s13063-022-06143-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2021] [Accepted: 03/03/2022] [Indexed: 11/10/2022] Open
Abstract
Objective This study aimed to verify the survival superiority of the combination of intraperitoneal perfusion and systemic chemotherapy over standard systemic chemotherapy. Methods A total of 78 advanced gastric cancer patients with malignant ascites were randomly divided into D-SOX group (intraperitoneal infusion of docetaxel 30 mg/m2 on d1 and d8, intravenous oxaliplatin 100 mg/m2 on d1, and oral administration of S-1 on d1-d14) and DOS group (intravenous docetaxel 60 mg/m2 on d1, intravenous oxaliplatin 100 mg/m2 on d1, and oral administration of S-1 on d1-d14). Efficacy of both groups was evaluated every 2 cycles with 21 days as a cycle. The primary endpoint was overall survival, and the secondary endpoints were objective response rate, ascites control rate, negative conversion rate of ascites cytology, and side effects. Results The median overall survival in D-SOX group was significantly higher than that in the DOS group (11.7 vs 10.3 months, HR 0.52, 95%CI 0.31–0.86, P = 0.005). The ascites control rate in the D-SOX group was 58.9% and 30.8% in DOS group (95%CI 42.8–75.1% vs 95%CI 15.6–45.9%, P = 0.012). Besides, the adverse reactions were tolerable in both groups, and patients in the D-SOX group had lower grade 3/4 blood toxicity than that in the DOS group (26% vs 54%, P = 0.01). Conclusion Compared with traditional systemic chemotherapy, docetaxel intraperitoneal infusion combined with chemotherapy has better therapeutic effect on gastric cancer ascites, with better survival benefit and tolerance and less hematological toxicity, which is worthy of further research and clinical application.

Abstract
Tumor vaccines, focusing on tailoring individual tumor antigens, have gained much attention in personalized tumor therapy. Recently, breakthroughs have been made in the development of tumor vaccines thanks to the progress in nanotechnology. We will summarize nanoparticle-mediated tumor vaccines for personalized therapy in this review. ROS/heat generating nanoparticles and molecules could induce immunogenic cell death and tumor antigen release in vivo. This strategy often includes chemotherapy, radiotherapy, photodynamic therapy, photothermal therapy, magneto-thermal therapy, etc. On the other hand, ex vivo technologies have been applied for processing of tumor cells/tissues to form effective tumor antigens, in which nanotechnology has shown very good prospects in delivering tumor antigens. In in vivo and ex vivo strategies, nanotechnology also could improve the immune effect through enhancing the uptake by targeting cells, reducing therapeutic drugs/agents, further encapsulating immuno-modulatory molecules or combining with other therapy treatments. Thus, therapeutic vaccines based on nanoparticles have the potential to enhance the immune response and reduce the side effects.

Abstract
Oral mucositis (OM) is a serious side effect of cancer chemotherapy. The pathobiology of oral mucositis remains incompletely understood due to lack of appropriate models which recapitulate the human condition. Existing rodent models are intraperitoneal and require radiation, chemical or mechanical injury to the chemotherapy protocol to induce oral lesions. We aimed to develop an OM mouse model that is induced solely by chemotherapy and reproduces macroscopic, histopathologic and inflammatory characteristics of the human condition. Female C57BL/6 mice were given intravenous 5-Fluorouracil (5-FU) injections every 48 hours, for 2 weeks. A high daily dose of intraperitoneal administration was tested for comparison. Mice were monitored daily for weight loss. Epithelial histomorphometric analyses in tongue, esophageal and intestinal tissues were conducted coupled with assessment of apoptosis, cell proliferation, neutrophilic infiltration and the integrity of adherens junctions by immunohistochemistry. Neutropenia was assessed in peripheral blood and bone marrow. Tissues were analyzed for pro-inflammatory cytokines at the protein and mRNA levels. Daily intraperitoneal administration of 5-FU led to rapid weight loss and intestinal mucositis, but no oral inflammatory changes. Intravenous administration triggered atrophy of the oral and esophageal epithelium accompanied by reduction in cell proliferation and increased apoptosis. Coincidental with these changes were up-regulation of NF-κB, TNFα, IL-1β, GM-CSF, IL-6 and KC. Despite neutropenia, increased oral neutrophilic infiltration and reduced E-cadherin was observed in oroesophageal mucosae. We developed a novel experimental tool for future mechanistic studies on the pathogenesis of chemotherapy-induced OM.

Abstract
Peritoneal metastasis is the most frequent pattern of gastric cancer recurrence or metastasis and is a definitive determinant of prognosis. However, an effective means of treating peritoneal disease has not yet been established. Systemic chemotherapy has only a limited effect on peritoneal metastasis, although some progress has been shown in terms of median survival time, especially among patients with a minimal or moderate disease burden. Clinical research related to intraperitoneal administration of anticancer drugs is currently underway. An advantage of intraperitoneal chemotherapy is the ability to achieve high concentrations of anticancer drugs in the peritoneal cavity and the direct exposure of peritoneal deposits and free cancer cells to those drugs. In addition, pharmacokinetic studies with taxanes have shown that these high intraperitoneal drug concentrations are sustained for a considerable length of time, allowing prolonged exposure. As taxanes are the most appropriate drugs for intraperitoneal administration, the development of repeated intraperitoneal chemotherapy using taxanes for gastric cancer peritoneal metastasis-either alone or in combination with systemic chemotherapy-has taken place over the past decade, mostly in Japan. Several phase II trials and a phase III trial have recently demonstrated the efficacy of this therapy, including median survival times of 14.4-24.6 months and one-year overall survival rates of 67-91%. These results may lead to the approval of intraperitoneal taxanes, especially paclitaxel, for official insurance coverage in the near future.

Conversion Surgery Post-Intraperitoneal Paclitaxel and Systemic Chemotherapy for Gastric Cancer Carcinomatosis Peritonei. Are We Ready? J Gastrointest Surg 2017; 21:425-433.

Abstract
Peritoneal metastasis is common in gastric cancer. It is difficult to treat and carries a poor prognosis. Intraperitoneal (IP) delivery of chemotherapy can attain a higher drug exposure in the peritoneal cavity but with reduced systemic toxicity. Therefore, we hypothesized that IP paclitaxel with systemic chemotherapy would be clinically beneficial for gastric cancer with peritoneal metastases. Patients with unresectable and/or recurrent gastric adenocarcinoma with peritoneal dissemination and/or positive peritoneal washing cytology were recruited. They underwent eight cycles of IP paclitaxel and systemic XELOX. The primary endpoint was 1-year overall survival rate and secondary endpoints were safety, response rate, and peritoneal cytological response. Patients who subsequently had no distant metastases and two consecutive negative peritoneal cytologies underwent conversion gastrectomy if there was no macroscopic evidence of peritoneal disease at diagnostic laparoscopy. Twenty-two patients were enrolled, receiving at least one cycle of IP paclitaxel at the time of reporting (data cutoff-March 11, 2016). The median number of cycles was 7.5. The median overall survival was 18.8 months, and the 1-year survival rate was 72.2%. One patient died of neutropenic sepsis. Of 19 evaluable patients with measurable disease, 7 (36.8%) achieved PR, 8 (42.1%) achieved SD, and 4 (21.1%) experienced PD. Peritoneal cytology turned negative in 11 of 17 (64.7%) patients. Six patients underwent conversion gastrectomy (4 R0, 2 R1) with a median survival of 21.6 months (range = 8.7-29.9 months). XELOX and IP paclitaxel appears to be an effective regimen in gastric cancer with peritoneal metastases. Conversion gastrectomy may be considered in patients with a favorable response.

Preoperative intraperitoneal oxaliplatin for unresectable peritoneal carcinomatosis of colorectal origin: a pilot study. Pleura Peritoneum 2016; 1:209-215. [PMID: 30911625 DOI: 10.1515/pp-2016-0018] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2016] [Accepted: 11/02/2016] [Indexed: 02/07/2023] Open
Abstract
Background Peritoneal carcinomatosis in colorectal cancer is an advanced stage of the disease where improved survival can be attained whenever the resection associated with hyperthermic intreperitoneal chemotherapy is possible. In unresectable cases, systemic chemotherapy is administered to obtain conversion to resectability but results have not yet been clearly evaluated. Local chemotherapy in this setting has been proven useful in several similar situations. The aim of the present pilot study was to evaluate the feasibility of pre-operative intraperitoneal chemotherapy with oxaliplatin in these patients. Methods Six patients with unresectable peritoneal disease of colorectal origin were included in the study. An intraperitoneal implantable chamber catheter was inserted during the laparotomy that evaluated the extent of the peritoneal disease (peritoneal carcinomatosis index 25 to 39). Patients then underwent intraperitoneal chemotherapy with oxaliplatin 85 mg/m2 in combination with systemic chemotherapy (FOLFIRI or simplified LV5FU) and a targeted therapy every 2 weeks. Results Two catheter perfusion incidents were reported due to the abdominal wall thickness. Two patients completed the four intraperitoneal (IP) chemotherapy cycles without major toxicity. One patient developed grade 3 or 4 diarrhea requiring a short intensive care unit (ICU) stay, though it is not clear whether the event was induced by intravenous irinotecan, IP oxaliplatin or the combination of both. Grade 3 fatigue and abdominal pain were also recorded. For one patient with aggressive disease, best supportive care was initiated after the first course of chemotherapy. Conclusions Our study is the first to assess intraperitoneal oxaliplatin-based chemotherapy in the preoperative setting for patients with unresectable peritoneal metastases. The tolerance was acceptable for 85 mg/m2 IP oxaliplatin combined with systemic therapy in these patients. Our results justify carrying on with a phase I/II trial to determine the recommended dose of oxaliplatin in this clinical context and its efficacy.
