Recurrent gastric cancer sustaining a partial response after the nivolumab discontinuation because of immune-related adverse events: a case report. Surg Case Rep 2020; 6:271. [PMID: 33074364 PMCID: PMC7572942 DOI: 10.1186/s40792-020-01050-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Accepted: 10/15/2020] [Indexed: 11/16/2022] Open
Abstract
Background The prognosis of patients with recurrent gastric cancer is poor despite chemotherapy being clinically recommended as the first therapeutic strategy. Recent clinical trials have established the clinical utility of nivolumab in the third-line treatment of such patients. Immune-related adverse events (irAE) have been focused as a promising predictor for tumor response to nivolumab. This report aims to present a long-term survivor of recurrent gastric cancer who was followed up without any treatments after the nivolumab discontinuation because of irAE. Case presentation A 65-year-old male with stage III gastric cancer (cT4aN1M0) underwent surgery after neoadjuvant chemotherapy. Owing to the final pathological stage IIIB (ypT4bN1M0), the patient received adjuvant chemotherapy. Nevertheless, during adjuvant chemotherapy 1-year post-surgery, computed tomography (CT) revealed lymph node swelling in station no. 9. Thus, upon diagnosis with lymph node recurrence, the patient was treated with two courses of capecitabine + oxaliplatin and three courses of ramucirumab + paclitaxel as the first- and second-line regimens, respectively. Based on these regimens, the patient had a progressive disease to chemotherapy. Consequently, we administered nivolumab as the third-line regimen. After four courses of nivolumab, CT revealed a significant shrinkage of the metastatic lymph node, with a 45.6% reduction. We confirmed a partial response during 11 courses of nivolumab. Since the occurrence of grade 4 diabetes mellitus after 12 courses of nivolumab, the patient was followed up without any treatment after the nivolumab discontinuation. Currently, the patient remains a partial response for 15 months, since the nivolumab discontinuation and is alive for 31 months after disease recurrence. Conclusions Acute irAE during nivolumab chemotherapy could be one of the crucial clinical factors to predict tumor suppression in patients with advanced gastric cancer.

Abstract
BACKGROUND A unique time in which to effectively treat an intraabdominal malignancy is the time at which the surgeon attempts complete removal of the malignant process. Although surgery is effective for visible disease, micrometastases or multiple small cancer nodules are not amenable to resection. Alternative interventions to deal with residual disease disseminated on peritoneal surfaces are needed. MATERIALS AND METHODS Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) can be combined with early postoperative intraperitoneal chemotherapy (EPIC) in order to maximally treat gross disease within the abdomen and pelvis and also the minimal residual disease that exists in many patients after resection. The third component of this treatment for ovarian malignancy was EPIC paclitaxel in this study. The clinical features, pharmacologic assessments, and survival were determined in ovarian cancer patients in whom EPIC was added to the perioperative treatment plan. RESULTS Patients with high grade serous ovarian cancer underwent CRS, HIPEC with cisplatin/doxorubicin, and EPIC paclitaxel. These treatments combined as a single intervention were studied in 10 patients. The median number of peritonectomy procedures was 1, the median number of visceral resections was 5, and the median time required in the operating room was 8 h. Two patients had a class 3 adverse event. The median survival of patients was 50 months. Pharmacokinetic analysis of the intraperitoneal paclitaxel showed 252 ± 153 times exposure of peritoneal surfaces as compared to intravenous exposure when the drug was instilled into the peritoneal space. CONCLUSIONS EPIC paclitaxel was successfully combined with CRS and HIPEC in 10 patients with ovarian cancer. The treatment was tolerated approximately the same as other major cytoreductive surgical procedures for ovarian cancer or other malignancies. Survival of these ovarian cancer patients seemed unusually prolonged as compared to other patients with stage 3b or recurrent disease. In this pilot study CRS, HIPEC and EPIC were safe and effective.

Abstract
Aim: To study the value and efficiency of CEA/CA72-4 immunohistochemistry in detecting free tumor cells from peritoneal lavage, in order to provide reliable lab information for subsequent intraperitoneal chemotherapy. Methods: A total of 112 progressive gastric cancer patients were enrolled from Oct. 2016 to Oct 2017, who were pathologically diagnosed as gastric cancer after surgery. Peritoneal lavage was respectively collected during operation. Cytology and CEA/CA72-4 immunohistochemistry of peritoneal lavage samples was performed. Overall survival and recurrence free survival was analyzed. Results: Cytology showed 16 positive cases (14.29%), CEA immunohistochemistry showed 29 positive cases (25.89%), CA72-4 immunohistochemistry showed 33 positive cases (29.46%). McNemar's test showed significant difference in positivity between cytology (CY+) and CEA/CA72-4 immunohistochemistry (IHC+). Kappa test showed consistency between immunohistochemistry of CEA and CA72-4 with cytology. Patients with CY+/IHC+ had the poorest overall survival (OS) as well as recurrence free survival (RFS), followed by those with CY+ or IHC+, while those with CY-/IHC- had higher OS and RFS. The differences of OS and RFS in IHC+ group were worse than that in IHC- group. Kaplan-Meier analysis showed that positive CEA/CA72-4 IHC revealed poorer prognosis than the negative cases. Conclusions: Due to the limitation of cytology, combination of cytology and immunohistochemistry appears to be more efficient for predicting prognosis of progressive gastric cancer.

Abstract
PURPOSE Prognosis after peritoneal metastases in colorectal cancer is worse than that after lung or liver metastases. Previously, we demonstrated the safety of intraperitoneal (ip) administration of paclitaxel (PTX) combined with mFOLFOX6/CapeOX plus bevacizumab for colorectal cancer with peritoneal metastasis in a phase-I trial. Here, we evaluated the efficacy of this chemotherapy. METHODS We enrolled six patients with histologically confirmed peritoneal metastases secondary to colorectal cancer. PTX was administered through a peritoneal access port, in combination with oxaliplatin-based systematic chemotherapy. Response rate, progression-free survival, 1-year survival rate, frequency of improvement in peritoneal cancer index (PCI), and cytology in peritoneal lavage were evaluated. This study was registered in the University Hospital Medical Information Network Clinical Trial Registry on July 1, 2016 (UNIN000022924). RESULTS Three patients received the mFOLFOX6-bevacizumab regimen, whereas the other three received the CapeOX-bevacizumab regimen. The response rate was 25%. PCI score improved in 50% of the cases. Peritoneal lavage cytology that was positive in five patients before initiating the chemotherapy turned negative during chemotherapy in all patients. One-year survival rate was 100%, progression-free survival was 8.8 months (range, 6.8-12 months), and median survival time was 29.3 months. CONCLUSION The ip administration of PTX with systemic chemotherapy can potentially control peritoneal metastases in colorectal cancer.

A Case of Peritoneal Dissemination and Splenic Metastasis after Gastric Cancer Surgery That Could Be Controlled with Multidisciplinary Treatment. Case Rep Oncol 2020; 13:1164-1170.

Abstract
Splenic metastasis is known to occur at the terminal stage of cancer. While peritoneal dissemination is the most frequent recurrence of gastric cancer, metastasis to the spleen from gastric cancer is very rare. Splenectomy is currently the most effective probable treatment for solitary splenic metastasis of gastric cancer; it provides a good patient prognosis. However, careful consideration of surgical indications is required, as splenic metastasis is typically accompanied by multi-organ metastasis and dissemination. One of the main cancer treatment methods is the “wait-and-see” approach using chemotherapy. In general, patients with gastric cancer are treated with systemic chemotherapy for distant metastases including peritoneal dissemination. Radiotherapy is not commonly used to prolong life in patients with gastric cancer as gastric cancer is predominantly adenocarcinoma. However, a recent report indicated that chemo-radiotherapy was performed successfully for unresectable gastric cancer, including peritoneal dissemination. Here, we present the case of a 67-year-old patient who was observed to have peritoneal dissemination and splenic metastasis after gastric cancer surgery. Once the peritoneal dissemination was localized, surgical excision and chemo-radiotherapy were performed. We treated the splenic metastasis with the “wait-and-see” strategy with chemotherapy. A complete response on imaging in accordance with the Response Evaluation Criteria in Solid Tumors was achieved using multidisciplinary treatment. Our strategy of intensive multidisciplinary therapy could be a treatment option for cases with peritoneal dissemination or splenic metastasis of gastric cancer.

Abstract
Background Fluoropyrimidine-based regimens are the cornerstone of first-line chemotherapy for metastatic gastric cancer (GC). Capecitabine or S-1 might be used as an alternative to infusional 5-fluorouracil, especially in pan-Asian. This study aimed to compare the clinical outcomes of capecitabine-based and S-1-based regimens as first-line chemotherapy in Chinese patients with unresectable or metastatic GC. Methods We conducted a retrospective study including unresectable or metastatic GC patients treated with the capecitabine-based or S-1-based regimen as first-line chemotherapy at the First Hospital of China Medical University. Propensity score matching (PSM) analysis was performed to reduce selection bias. Overall survival (OS) outcomes were compared using the Kaplan-Meier method and log-rank test. Prognostic significance was determined using multivariate Cox regression analysis. In addition, subgroup analyses were conducted to determine the effectiveness of capecitabine-based and S-1-based regimens in clinically relevant patient subsets. Results The clinical data of 469 patients included between October 2005 and September 2018. PSM analysis identified 187 patients receiving capecitabine-based or S-1-based regimen. No significant difference in OS (10.7 vs. 11.1 months, P=0.523) was detected between the two groups after PSM. In the subgroup analysis, the median OS (12.2 vs. 9.3 months, P=0.013) was longer for patients with peritoneum metastasis who received the capecitabine-based regimen compared to those who received the S-1-based regimen. Conclusions No significant difference in clinical outcomes was observed between the capecitabine and S-1-based regimen as first-line chemotherapy for metastatic or unresectable GC patients in China. The capecitabine-based regimen should be considered in the treatment of the GC patients with peritoneum metastasis.

Abstract
OBJECTIVE Although chemotherapy has been clinically recommended as the initial treatment for patients with peritoneal dissemination of gastric cancer, poor prognosis has been noted among the same patients. However, the prognostic significance of conversion surgery after chemotherapy remains unclear. The present study therefore aimed to assess the clinical impact of conversion surgery among patients with peritoneal dissemination of gastric cancer. METHODS A total of 93 patients with peritoneal dissemination of gastric cancer undergoing chemotherapy between February 2002 and October 2019 were retrospectively enrolled and subsequently divided into progressive disease (PD) and non-PD groups based on tumor response to chemotherapy. RESULTS Among the included patients, 17 developed distant metastases at another site besides peritoneal dissemination. Based on tumor response, 24 and 69 patients were determined to have PD and non-PD, respectively, with the former having significantly poorer prognosis than the latter (p < 0.0001). A total of 19 patients underwent conversion surgery after chemotherapy, with the presence or absence of conversion surgery being significantly correlated with age, first-line chemotherapy regimen, and tumor response (p = 0.0134, p = 0.0337, and p = 0.0024, respectively). Patients in the non-PD group who underwent conversion surgery or chemotherapy alone had 3-year overall survival rates of 55.6 and 6.6%, respectively. Multivariate analysis identified conversion surgery alone as an independent prognostic factor in the non-PD group (p < 0.0001). CONCLUSION Our retrospective study demonstrated that conversion surgery for gastric cancer with peritoneal dissemination might improve the prognosis of responders who developed no peritoneal dissemination after chemotherapy.

Abstract
PURPOSE A phase I study of intraperitoneal paclitaxel (ip PTX) combined with gemcitabine (GEM) plus nab-paclitaxel (nab-PTX) (GnP) was conducted to determine the maximum tolerated dose (MTD) and the recommended dose (RD) in pancreatic cancer patients with peritoneal metastasis in first-line setting. METHODS Based on the 3 + 3 dose-escalation model, ip PTX, GEM and nab-PTX were administered at doses of 20 or 30 mg/m2, 800 or 1000 mg/m2 and 100 or 125 mg/m2 (level 1, 2 and 3, respectively) on days 1, 8 and 15 in 4-week cycles. Dose-limiting toxicity (DLT) defined as severe adverse events was evaluated during the first cycle of the treatment. Safety and preliminary efficacy were also investigated. RESULTS In total, 12 patients were enrolled. While 2 of the first 6 patients enrolled at level 1 experienced DLTs (grade 3 ip port dysfunction and grade 3 pneumonia), no DLT was observed in the next 6 patients enrolled at level 2 and 3. Therefore, we did not reach the MTD and the RD was determined to be level 3 (ip PTX of 30 mg/m2, GEM of 1000 mg/m2, and nab-PTX of 125 mg/m2). The major grade 3/4 adverse events included neutropenia (58%), anemia (33%), and ip port dysfunction (25%). The response rate was 25% and the median PFS was 5.4 (95% confidence interval; 2.4-16.0). The cytological status in peritoneal lavage turned negative in 8 patients (67%). CONCLUSIONS Ip PTX combined with GnP was feasible and potentially effective in pancreatic cancer with peritoneal metastasis as a first-line treatment deserved further evaluations.

Clinical Impact of Delayed Initiation of Adjuvant Chemotherapy Among Patients With Stage II/III Gastric Cancer: Can We Do Better? Front Oncol 2020; 10:1149. [PMID: 32850326 PMCID: PMC7412732 DOI: 10.3389/fonc.2020.01149] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Accepted: 06/08/2020] [Indexed: 12/24/2022] Open
Abstract
Background: To investigate the prognostic effects and risk factors of the omission and delay of postoperative chemotherapy of stage II/III gastric cancer (GC). Methods: The clinicopathological data of 1,520 patients undergoing radical gastrectomy for stage II/III GC were collected and retrospectively analyzed. We defined the chemotherapy delayed until more than 60 days after radical gastrectomy and the complete omission of chemotherapy as unacceptable chemotherapy initiation (UAC), whereas the chemotherapy conducted within 60 days of radical gastrectomy was defined as acceptable chemotherapy initiation (AC). The survival between the two groups was compared, and the trends and risk factors of UAC were analyzed. Results: There were 539 (35.5%) patients with UAC. The overall survival (OS) and disease-free survival of the UAC group patients were significantly inferior to those in the AC group (p < 0.001). Cox multivariate analysis demonstrated that UAC is an independent predictor of OS (p < 0.05). The OS and disease-free survival of the patients in the UAC group were close to those of the patients without chemotherapy (p > 0.05). Logistic analysis showed that female, old age, a self-paid status, a very low social status, high American Society of Anesthesiologists scores, intra-abdominal surgery history, and serious postoperative complications were independent risk factors of UAC (all p < 0.05). The radar chart shows the risk factors of UAC changed with time. Conclusions: UAC after radical gastrectomy is an independent risk factor for the prognosis of stage II/III GC patients. However, no significant decline of UAC has been achieved recently and should call for the attention of both government and clinicians.

Abstract
Background: To identify associated risk factors and develop a predictive nomogram for the early death of metastatic gastric cancer patients. Methods: A total of 4575 patients in the SEER cohort and 220 patients in the Chinese cohort diagnosed with metastatic gastric cancer in our Cancer Center were obtained. Univariate and multivariate logistic regression models were used to identify independent risk variables for early death. A predictive nomogram and a web-based probability calculator were developed and then validated by receiver operating characteristics (ROCs) curve and calibration plot in a Chinese cohort. Results: Eight independent variables, including race, grade, surgery, chemotherapy, and metastases of bone, brain, liver, lung were recognized by using univariate and multivariate logistic regression models for identifying independent risk variables of early death about metastatic gastric cancer patients. By comprising these variables, a predictive nomogram and a web-based probability calculator were constructed in the SEER cohort. Then, it could be validated well in the Chinese cohort by receiver operating characteristics (ROCs) curve and calibration plot. Conclusion: Using this nomogram model provided an insightful and applicable tool to distinguish the early death of metastatic gastric cancer patients.

Abstract
PURPOSE Although laparoscopic hyperthermic intraperitoneal chemotherapy (LS-HIPEC) has been proven safe in patients with gastric adenocarcinoma and carcinomatosis or positive cytology, patient selection criteria remain unclear. Thus, we perform a retrospective analysis to identify factors associated with improved survival and resection rates. PATIENTS AND METHODS Data for all patients undergoing LS-HIPEC for stage IV gastric adenocarcinoma between June 2014 and November 2018 were collected prospectively and analyzed for associations with survival and resection using uni- and multivariate logistic regression, Cox proportional hazards models, and Kaplan-Meier survival functions. RESULTS Of 70 patients who underwent LS-HIPEC, 43 (61%) received two drugs (mitomycin C and cisplatin), and 27 (39%) received three drugs (mitomycin C, cisplatin, and paclitaxel). The two groups' demographic and oncologic differences were not significant, although the three-drug group had a significantly lower rate of radiation therapy use (58% vs. 15%; p < 0.01). Univariate analysis revealed that poor differentiation [Cox hazard ratio (HR) 2.75; 95% confidence interval (CI) 1.34-5.63; p < 0.01], gross carcinomatosis (HR 3.10; 95% CI 1.52-6.30; p = 0.03), and ascites (HR 3.43; 95% CI 1.88-6.26; p < 0.01) were associated with shorter median survival. Gastrectomy was associated with improved overall survival (HR 0.32; 95% CI 0.15-0.70; p < 0.01). The resection rate of the 45 patients without ascites (38%) was significantly higher than that of the 25 patients with ascites (0%; p < 0.01). CONCLUSIONS Our findings identify ascites as a significant prognostic factor for gastric cancer patients with peritoneal metastases undergoing LS-HIPEC. Our findings can be used to help identify patients who are unlikely to proceed to resection after LS-HIPEC and are good candidates for novel therapeutic approaches or clinical trials.

Abstract
INTRODUCTION Peritoneal carcinomatosis is difficult to treat. Pressurized Intra-Peritoneal Aerosolised Chemotherapy (PIPAC) is a novel method of delivering chemotherapy to the peritoneal cavity, aiming for homogenous and deeper drug distribution. To date, limited chemotherapeutics have been used with promising results. Here, we evaluate the pharmacokinetics, peritoneal tissue drug concentration, penetration, and short-term safety of PIPAC using solvent-based paclitaxel in swine to guide clinical trials. MATERIALS AND METHODS PIPAC solvent-based paclitaxel was administered at 60, 30, and 15mg/m2 for 3 cohorts. Each PIPAC procedure was followed by intravenous (IV) administration of the same dose of solvent-based paclitaxel on Day 7, serving as control for pharmacokinetic comparison in the same pig. Safety and toxicity were evaluated by clinical assessment, blood counts and biochemistry. Blood samples were taken for pharmacokinetic analysis. Peritoneal biopsies were taken to measure tissue paclitaxel concentrations and distribution. RESULTS 12 Yorkshire x Landrace pigs underwent trial procedures. With PIPAC, there was linear pharmacokinetics and lower systemic exposure to paclitaxel compared to IV administration. MALDI-MSI demonstrated concentration of paclitaxel at the peritoneal surface, with estimated 2 mm penetration. PIPAC paclitaxel had favorable toxicity profile. The most significant adverse event was neutropenia which was dose dependent, with absolute neutrophil count <1.0 × 103/μL seen at the highest dose. One pig developed grade 2 hypersensitivity reaction during IV infusion and one death occurred during the PIPAC procedure, likely from anaphylaxis; these are known potential adverse events mandating standard precautions and monitoring. CONCLUSION PIPAC paclitaxel at 15mg/m2 may be considered for a Phase I study.

Abstract
BACKGROUND Intraperitoneal chemotherapy using paclitaxel is considered an experimental approach for treating peritoneal carcinomatosis. This study aimed to determine the recommended dose, and to evaluate the clinical efficacy and safety, of the combination of intravenous gemcitabine, intravenous nab-paclitaxel and intraperitoneal paclitaxel in patients with pancreatic cancer and peritoneal metastasis. METHODS The frequencies of dose-limiting toxicities were evaluated, and the recommended dose was determined in phase I. The primary endpoint of the phase II analysis was overall survival rate at 1 year. Secondary endpoints were antitumour effects, symptom-relieving effects, safety and overall survival. RESULTS The recommended doses of intravenous gemcitabine, intravenous nab-paclitaxel and intraperitoneal paclitaxel were 800, 75 and 20 mg/m2 respectively. Among 46 patients enrolled in phase II, the median time to treatment failure was 6·0 (range 0-22·6) months. The response and disease control rates were 21 of 43 and 41 of 43 respectively. Ascites disappeared in 12 of 30 patients, and cytology became negative in 18 of 46. The median survival time was 14·5 months, and the 1-year overall survival rate was 61 per cent. Conversion surgery was performed in eight of 46 patients, and those who underwent resection survived significantly longer than those who were not treated surgically (median survival not reached versus 12·4 months). Grade 3-4 haematological toxicities developed in 35 of 46 patients, whereas non-haematological adverse events occurred in seven patients. CONCLUSION Adding intraperitoneal paclitaxel had clinical efficacy with acceptable tolerability.

Abstract
BACKGROUND The prognosis of gastric cancer peritoneal carcinomatosis (GCPC) remains poor despite recent advances in systemic chemotherapy (SC) with an average survival less than 6 months. Current evidence supporting the utility of hyperthermic intraperitoneal chemotherapy (HIPEC) combined with SC for GCPC is limited. We plan to provide a systematic review and meta-analysis of randomized controlled trials to evaluate the comparative effects and safety of HIPEC combined with SC in the management of GCPC. METHODS Randomized controlled trials evaluating HIPEC combined with SC versus SC as first-line treatment for GCPC will be searched in MEDLINE, EMBASE, Web of Science, the Cochrane Library, ClinicalTrials.gov, and Google Scholar, from database inception to April 30, 2020. Data on study design, participant characteristics, intervention details, and outcomes will be extracted. Primary outcomes to be assessed are: median progression-free survival; secondary outcomes are: median survival time, 1- year survival rate, 2-year survival rate, objective response rate, and adverse events. Meta-analysis will be performed using RevMan V.5.3 statistical software. Data will be combined with a random effect model. Study quality will be assessed using the Cochrane Risk of Bias Tool. Heterogeneity will be assessed, and if necessary, a subgroup analysis will be performed to explore the source of heterogeneity. RESULTS The results will provide useful information about the effectiveness and safety of HIPEC combined with systemic chemotherapy regimens in patients with gastric cancer peritoneal carcinomatosis. CONCLUSION The findings of the study will be disseminated through peer-reviewed journal. THE REGISTRATION NUMBER INPLASY202050006. DOI NUMBER 10.37766/inplasy2020.5.0006.

Minimally invasive surgery is feasible after preoperative chemotherapy for stage IV gastric cancer. Ann Gastroenterol Surg 2020; 4:396-404. [PMID: 32724883 PMCID: PMC7382436 DOI: 10.1002/ags3.12343] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Revised: 03/11/2020] [Accepted: 03/18/2020] [Indexed: 12/23/2022] Open
Abstract
AIM To elucidate the safety and feasibility of minimally invasive surgery (MIS) as conversion surgery after chemotherapy for stage IV gastric cancer, we compared the background characteristics and clinical courses of patients who underwent open conversion surgery (open group) versus MIS (MIS group). METHODS We included 94 consecutive patients with stage IV gastric cancer who received chemotherapy followed by conversion surgery gastric resection from January 2011 to October 2019 at the Osaka International Cancer Institute in this analysis. RESULTS The open group included more patients who had macroscopic peritoneal metastasis and required splenectomy. However, other background characteristics, including preoperative chemotherapy duration, were comparable. The MIS group had significantly longer operative time (266 vs 339 minutes, P = .0039) and less operative blood loss (520 vs 10 mL, P < .0001). The incidence of postoperative complication of Clavien-Dindo grade II or higher was non-significantly lower (24.5% vs 9.8%, P = .058) and length of postoperative hospital stay was significantly shorter in the MIS group (12 vs 8 days, P < .0001). Even though the open group included more patients with more advanced (ypT4a or higher, or N3) disease, the MIS group had better recurrence free survival and overall survival (OS). Multivariate analysis revealed that N status (hazard ratio [HR], 4.39; 95% confidence interval [CI], 2.18-12.26; P < .0001) and T status (2.11; 1.05-4.36; P = .036) were independent prognostic factors for OS. MIS was not a negative prognostic factor for OS (HR, 0.44; 95% CI, 0.15-1.10; P = .081). CONCLUSION MIS can be safely performed as conversion surgery following chemotherapy for stage IV gastric cancer.

Boosting Replication and Penetration of Oncolytic Adenovirus by Paclitaxel Eradicate Peritoneal Metastasis of Gastric Cancer. MOLECULAR THERAPY-ONCOLYTICS 2020; 18:262-271.

Abstract
Peritoneal metastasis is the most frequent form of distant metastasis and recurrence in gastric cancer, and the prognosis is extremely poor due to the resistance of systemic chemotherapy. Here, we demonstrate that intraperitoneal (i.p.) administration of a green fluorescence protein (GFP)-expressing attenuated adenovirus with oncolytic potency (OBP-401) synergistically suppressed the peritoneal metastasis of gastric cancer in combination with paclitaxel (PTX). OBP-401 synergistically suppressed the viability of human gastric cancer cells in combination with PTX. PTX enhanced the antitumor effect of OBP-401 due to enhanced viral replication in cancer cells. The combination therapy increased induction of mitotic catastrophe, resulting in accelerated autophagy and apoptosis. Peritoneally disseminated nodules were selectively visualized as GFP-positive spots by i.p. administration of OBP-401 in an orthotopic human gastric cancer peritoneal dissemination model. PTX enhanced the deep penetration of OBP-401 into the disseminated nodules. Moreover, a non-invasive in vivo imaging system demonstrated that the combination therapy of i.p. OBP-401 administration with PTX significantly inhibited growth of peritoneal metastatic tumors and the amount of malignant ascites. i.p. virotherapy with PTX may be a promising treatment strategy for the peritoneal metastasis of gastric cancer.

Abstract
BACKGROUND Current national guidelines do not include hyperthermic intraperitoneal chemoperfusion (HIPEC) as treatment for gastric cancer, and there are no completed clinical trials of cytoreduction, gastrectomy, and HIPEC from the US. METHODS Patients with gastric adenocarcinoma and positive peritoneal cytology or carcinomatosis who had completed systemic chemotherapy and laparoscopic HIPEC underwent cytoreduction, gastrectomy, and HIPEC with 30 mg mitomycin C and 200 mg cisplatin. The primary endpoint was overall survival (OS), with a secondary endpoint of postoperative complications (NCT02891447). RESULTS We enrolled 20 patients from September 2016 to March 2019. Six patients had positive cytology only and 14 had carcinomatosis. All patients were treated with systemic chemotherapy with a median of eight cycles (range 5-11 cycles) and at least one laparoscopic HIPEC. The median peritoneal carcinomatosis index at cytoreduction/gastrectomy/HIPEC was 2 (range 0-13). After surgery, the 90-day morbidity and mortality rates were 70% and 0%, respectively. Median length of hospital stay was 13 days (range 7-23 days); median follow-up was 33.5 months; median OS from the date of diagnosis of metastatic disease was 24.2 months; and median OS from the date of cytoreduction, gastrectomy, and HIPEC was 16.1 months. 1-, 2-, and 3-year OS rates from the diagnosis of metastatic disease were 90%, 50%, and 28%, respectively. CONCLUSIONS Survival rates for patients with gastric adenocarcinoma and peritoneal disease treated with cytoreduction, gastrectomy, and HIPEC are encouraging; our early results are similar to those of recent prospective registry studies. Multi-institutional and cooperative group trials should be supported to confirm survival and safety outcomes.

Abstract
BACKGROUND The present study aims to report the surgical outcome and long-term survival of conversion surgery and clarify its role in advanced gastric cancer. PATIENTS AND METHODS A total of 95 primary advanced gastric adenocarcinoma patients who underwent systemic chemotherapy and conversion surgery were reviewed retrospectively. The survival of conversion surgery was analyzed by Cox regression and the Kaplan-Meier method. Surgical outcomes were analyzed according to the Clavien-Dindo classification. RESULTS The median survival time (MST) of the 95 patients was 26.8 months, and the postoperative MST was 19.3 months. The MSTs of the patients in categories 1, 2, 3, and 4 were 28.8, 25.5, 43.6, and 11.3 months, respectively. The MSTs of the patients who underwent R0 resection (47 cases) and R1/2 resection (48 cases) were 49.3 months and 21.9 months, respectively. The MST of patients treated with total gastrectomy was shorter (21.9 months) than that of patients who underwent proximal (55.0 months) or distal (46.3 months) gastrectomy. Patients who received more than 6 cycles of induction chemotherapy had a longer MST than patients who received 3-5 cycles or 1-2 cycles (MST: 55.0 months versus 21.1 months versus 21.7 months). The incident postoperative complications and postoperative mortality rates were 10.5% and 1.1%, respectively. CONCLUSIONS Advanced gastric cancer patients may obtain a survival benefit from conversion surgery, except category 4. Performing a sufficient number of cycles of induction chemotherapy (usually ≥ 6 cycles) is recommended. Surgical oncologists should perform R0 resection and avoid total gastrectomy.

Abstract
BACKGROUND Few patients affected by gastric cancer peritoneal metastasis (GCPM) are offered locoregional treatment, despite several proof-of-efficacy trials. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) has emerged in recent years as a promising tool to control peritoneal carcinomatosis. The combination of PIPAC with systemic chemotherapy may offer a greater clinical benefit than standard treatment alone. METHODS A single-center cohort of 28 consecutive patients affected by GCPM was scheduled for bidirectional treatment, comprising PIPAC and systemic chemotherapy, from September 2017 to September 2019. Data recorded included safety, efficacy and survival outcomes. Ascite volumes, the Peritoneal Cancer Index (PCI) and pathological response through the Peritoneal Regression Grading Score (PRGS) were compared in those patients who underwent more than one PIPAC procedure. RESULTS Forty-six PIPAC procedures were administered, with a mean of 1.7 PIPAC procedures per patient. The median time to resume systemic chemotherapy after PIPAC was 6 days (range 4-7). Concerning safety, two grade 3-4 CTCAE (Common Terminology Criteria for Adverse Events v4.0) toxicity events and one intraoperative complication were recorded. Thirteen patients repeated PIPAC. A pathological response was recorded in 61.5% of patients (one with complete and seven with partial regression). The median overall survival was 12.3 months in the overall population and 15.0 months in patients undergoing more than one PIPAC procedure. CONCLUSIONS A bidirectional approach for GCPM was feasible and safe, as the PIPAC procedure integrates well with several systemic chemotherapy regimens. The pathological response demonstrated the antitumoral efficacy of PIPAC. The proposed bidirectional approach may be further investigated in the first-line treatment of metastatic gastric cancer.

Abstract
Background A new treatment using bidirectional intraperitoneal (IP) and intravenous (IV) chemotherapy developed by Asiatic surgeons improves outcomes in patients with synchronous peritoneal metastasis (PM) from gastric cancer (GC). Methods We enrolled six consecutive patients with unresectable PM from GC who underwent bidirectional chemotherapy using IP docetaxel and IV FOLFOX or LV5FU2. In one course, IP docetaxel 30 mg/m2 was administrated on days 1, 8 and 15, and IV FOLFOX or LV5FU2 was administered on days 1 and 15, followed by 7 days of rest. Before and after a complete bidirectional cycle of three courses, the peritoneal cancer index (PCI) was evaluated by laparoscopy. The primary endpoint was to evaluate the feasibility and safety of bidirectional chemotherapy. Secondary endpoints were overall survival (OS), and the success of the therapeutic strategy was reflected by a decrease of 25% of the initial PCI. Results All patients completed one bidirectional cycle. The regimen was well tolerated. The median OS was 13 months [range 5–18], and the 1-year OS rate was 67%. After the first bidirectional cycle, the PCI decrease ≥25% of the initial value in four patients. A major histological response was observed in four patients. Conclusions This is the first Western study and confirms the feasibility and safety of bidirectional treatment using IP and IV chemotherapy for patients with unresectable PM from GC, resulting in a 13-month median OS with limited morbidity. The decrease in PCI after one bidirectional cycle is promising.

Abstract
Background Despite recent advances in systemic chemotherapy, the prognosis of patients with peritoneal metastases from gastric cancer still remains poor. Nonetheless, several efficacious intraperitoneal chemotherapy regimens have recently been developed for patients with peritoneal metastases. However, no study has investigated the effectiveness of intraperitoneal chemotherapy for metachronous peritoneal metastases from gastric cancer after curative surgery. Case presentation We herein report a case of a 65-year-old man who had metachronous peritoneal metastases from gastric cancer after curative total gastrectomy who had been successfully treated with intraperitoneal chemotherapy. One month after surgery, adjuvant chemotherapy with S-1 was initiated given a final pathological stage of IIIB (pT4aN2M0). However, during adjuvant chemotherapy 12 months after surgery, tumor marker levels, which had been within normal range before surgery, increased with abdominal contrast-enhanced computed tomography (CT) revealing pelvic ascites. Thereafter, staging laparoscopy was performed, and the patient was diagnosed with peritoneal recurrence of gastric cancer. Following staging laparoscopy, an intraperitoneal access port was subcutaneously implanted for subsequent intraperitoneal chemotherapy. Combined chemotherapy with intraperitoneal and intravenous administration of paclitaxel and oral S-1 was then provided. After one course of combined chemotherapy, peritoneal lavage cytology was negative for malignancy. CT showed gradually decreasing ascites, whereas tumor marker levels returned to normal. The patient continued chemotherapy without major side effects and remained progression-free for 33 months with 36 chemotherapy cycles. Conclusions A combination regimen including intraperitoneal chemotherapy could be a promising option for patients with peritoneal recurrence after gastric cancer surgery.

Abstract
Background: Increasing evidences from phase II or III trials have proved that salvage systematic therapy, including chemotherapy, target therapy, or checkpoint inhibitor therapy can prolong survival in patients who do not succeed with second line therapy, yet there are no guidelines for the optimum third-line treatments. To compare the effectiveness and safety of current third-line therapies for metastatic Gastric Cancer (mGC), we conducted this network analysis. Methods: Literature up to Sep 30, 2019 were systematically searched and analyzed by a Bayesian fixed-effect model. Results: This study included seven randomized clinical trails which involved 2,655 patients. It turns out that for overall survival, nivolumab has the highest probability to be the optimal choice for overall survival (OS). For patients with no peritoneal metastases, the network meta-analysis showed that Nivolumab (HR:0.64; 95% CI: 0.48–0.85) and Trifluridine/tipiacil (HR:0.66; 95% CI: 0.51–0.86) were associated with significantly higher improvement in OS than placebo. However, patients with peritoneal metastases could not benefit from nivolumab, ramucirumab, or Trifluridine/tipiacil, when compared with a placebo. For progression-free survival, apatinib (850 mg) was the most likely candidate, followed by ramucirumab. Statistically, Apatinib (850 mg), Trifluridine/tipiacil, and SLC had higher incidences of high-grade adverse events (AEs) than placebo. Conclusion: Our findings demonstrate that nivolumab has the best balance between acceptability and effectiveness in the third line therapy for mGC.

Abstract
Peritoneal metastasis (PM) frequently occurs in patients with gastric cancer (GC) and confers a dismal prognosis despite advances in systemic chemotherapy. While systemic chemotherapy has poor peritoneal penetration, intraperitoneal (IP) chemotherapy remains sequestered, resulting in high peritoneal drug concentrations with less systemic side-effects. The first application of IP treatment was hyperthermic intraperitoneal chemotherapy (HIPEC) with cytoreductive surgery (CRS) for gastric cancer peritoneal metastasis (GCPM); but was associated with an increased morbidity and mortality rate without significantly improving overall survival (OS). While CRS confers limited benefit, the potential role of prophylactic HIPEC and laparoscopic neoadjuvant HIPEC are currently being evaluated. Combination systemic and IP chemotherapy (SIPC) gained popularity in the 1990s, since it provided the benefits of IP treatment while reducing surgical morbidity, demonstrating promising early results in multiple Phase II trials. Unfortunately, these findings were not confirmed in the recent PHOENIX-GC randomized controlled trial; therefore, the appropriate treatment for GCPM remains controversial. Small observational studies from Japan and Singapore have reported successful downstaging of PM in GC patients receiving SIPC who subsequently underwent conversion gastrectomy with a median OS of 21.6–34.6 months. Recently, the most significant development in IP-directed therapy is pressurized IP aerosol chemotherapy (PIPAC). Given that aerosol chemotherapy achieves a wider distribution and deeper penetration, the outcomes of multiple ongoing trials assessing its efficacy are eagerly awaited. Indeed, IP-directed therapy has evolved rapidly in the last 3 decades, with an encouraging trend toward improved outcomes in GCPM, and may offer some hope for an otherwise fatal disease.

Abstract
Advanced gastric cancer, especially scirrhous gastric cancer with peritoneal dissemination, remains refractory to conventional therapies. G47Δ, a third-generation oncolytic herpes simplex virus type 1, is an attractive novel therapeutic agent for solid cancer. In this study, we investigated the therapeutic potential of G47Δ for human gastric cancer. In vitro, G47Δ showed good cytopathic effects and replication capabilities in nine human gastric cancer cell lines tested. In vivo, intratumoral inoculations with G47Δ (2 × 105 or 1 × 106 plaque-forming units [PFU]) significantly inhibited the growth of subcutaneous tumors (MKN45, MKN74, and 44As3). To evaluate the efficacy of G47Δ for advanced-stage models of gastric cancer, we generated an orthotopic tumor model and peritoneal dissemination models of human scirrhous gastric cancer (MKN45-luc and 44As3Luc), which have features mimicking intractable scirrhous cancer patients. G47Δ (1 × 106 PFU) was constantly efficacious whether administered intratumorally or intraperitoneally in the clinically relevant models. Notably, G47Δ injected intraperitoneally readily distributed to, and selectively replicated in, disseminated tumors. Furthermore, flow cytometric analyses of tumor-infiltrating cells in subcutaneous tumors revealed that intratumoral G47Δ injections markedly decreased M2 macrophages while increasing M1 macrophages and natural killer (NK) cells. These findings indicate the usefulness of G47Δ for treating human gastric cancer, including scirrhous gastric cancer and the ones in advanced stages.

Abstract
The presence of peritoneal metastases in patients with advanced colorectal cancer is associated with poor prognosis but the mechanisms for this are unclear. This review summarises the current knowledge of the pathophysiology, clinical features, prevalence, prognosis, and molecular biology of peritoneal metastases and the risk factors for the development of peritoneal metastases following resection of a primary colorectal tumour. Furthermore, the evidence for treatment strategies are described including cytoreductive surgery, hyperthermic intraperitoneal chemotherapy, early post-operative intraperitoneal chemotherapy, sequential post-operative intraperitoneal chemotherapy and emerging novel strategies. Active areas of research should include the identification of individuals at high risk of peritoneal metastases after curative resection of primary tumour, development of a surveillance program for high-risk patients, optimisation of systematic therapies and further investigation of the use of intraperitoneal chemotherapy.

Abstract
Background Despite recent progress in systemic chemotherapy, the prognosis of patients with peritoneal metastases from gastric cancer is still poor. Efficacious intraperitoneal and systemic combination chemotherapy regimens to treat patients with peritoneal metastases have recently been developed. Case presentation A 74-year-old man with gastric cancer T4b (transverse mesocolon) N3 M1 (peritoneum) received combination chemotherapy with intraperitoneal administration of paclitaxel, intravenous oxaliplatin, and oral S-1. Eight courses of combined chemotherapy had remarkable anti-tumor effects on the primary lesion, lymph node metastases, and peritoneal metastases. Total gastrectomy with regional lymph node dissection was performed. Pathological examination revealed no viable tumor cells in the resected specimens. After gastrectomy, the patient received 25 courses of the same chemotherapy without oxaliplatin and has no evidence of recurrence 24 months later. Discussion Therapeutic approaches including systemic chemotherapy, extended resection, and heated intraperitoneal chemotherapy have been used to treat patients with peritoneal metastases. Repeat therapy with intraperitoneal paclitaxel has been used recently. Intraperitoneal administration of paclitaxel results in prolonged retention in the peritoneal cavity with effects against peritoneal metastases. Repeated administration of paclitaxel does not cause adhesions in the peritoneal cavity. When combination chemotherapy is effective, salvage gastrectomy is a promising option with minimal morbidity and mortality. Conclusion Combined chemotherapy with intraperitoneal paclitaxel and systemic chemotherapy followed by gastrectomy is a promising strategy for patients with advanced gastric cancer and peritoneal metastases.

Abstract
Purpose The objective of the present retrospective analysis was to describe the experience of intraperitoneal (IP) paclitaxel and systemic chemotherapy in patients with peritoneal metastasis (PM) of advanced gastric cancer (AGC) in a multicenter setting in Korea. Materials and Methods The medical records of patients with AGC, who were diagnosed with PM between January 2015 and December 2018, were reviewed. IP catheter was placed in the pouch of Douglas and was used for the administration of IP paclitaxel chemotherapy. Results We reviewed the clinical outcomes of IP paclitaxel and systemic chemotherapy administration in 82 patients at six institutions in Korea. Mean number of IP chemotherapy cycles was 6.6. The mean peritoneal cancer index (PCI) was 21.9. Postoperative complications related to IP catheter and port were observed in 15 patients. The overall median survival was 20.0 months. A significant difference was observed in the survival rate according to the ascites grade (grade I and II, 24.1 months; grade III and IV, 15.3 months; P=0.014) and PCI grade (grade I, 25.6 months; grade II and III, 16.3 months; P=0.023). Conclusions The feasibility of IP paclitaxel and systemic chemotherapy administration was demonstrated in this experience-based retrospective analysis suggesting that the procedure is beneficial in patients with PM of AGC.

Abstract
Pressurized intraperitoneal aerosol chemotherapy (PIPAC) represents a novel approach to deliver intraperitoneal chemotherapy. We report our experience with PIPAC in patients with peritoneal metastasis (PM) from gastric cancer (GC). Data from GC patients (n = 20) included in the prospective PIPAC-OPC1 and PIPAC-OPC2 studies are reported. All patients had received prior systemic chemotherapy. The mean peritoneal cancer index (PCI) was 10.5 (range 0-39) and nine patients had diffuse GC. PIPAC with cisplatin 7.5 mg/m2 and doxorubicin 1.5 mg/m2 were administered at 4-6-week intervals. Outcome criteria were objective tumour response, survival and adverse events. Twenty patients had 52 PIPAC procedures with a median follow-up of 10.4 months (3.3-26.5). Median survival from the time of PM diagnosis and after the first PIPAC procedure was 11.5 months and 4.7 months, respectively. Fourteen patients had repeated PIPAC (> 2), and the objective tumour response according to the histological peritoneal regression grading score (PRGS) was observed in 36%, whereas 36% had stable disease. Ten patients completed the three prescheduled sessions (per protocol group) and 40% of those displayed an objective tumour response, while 20% had stable disease. Only minor postoperative complications were noted, and none were considered causally related to the PIPAC treatment. PIPAC with low-dose cisplatin and doxorubicin can induce a quantifiable objective tumour response in selected patients with PM from GC. Survival data are encouraging and warrant further clinical studies.

Unusually favorable outcome of 6 consecutive patients with diffuse malignant peritoneal mesothelioma treated with repeated doses of intraperitoneal paclitaxel. A case series. Surg Oncol 2020; 33:96-99.

Abstract
BACKGROUND Diffuse malignant peritoneal mesothelioma (DMPM) is a disease in transition. Two decades ago this cancer had a median survival of 1 year. Recent reports in selected patients show a 5-year survival of 70% and median survival not reached at 10 years. METHODS Consecutive patients with a biopsy-confirmed diagnosis of DMPM, epithelial type, were treated by a consistent treatment plan. Cytoreductive surgery using peritonectomy procedures was always the first intervention. In the operating theater after all resections were complete but prior to intestinal reconstruction, hyperthermic intraperitoneal chemotherapy (HIPEC) using 2 cytotoxic agents was given. An intraperitoneal port was placed for normothermic intraperitoneal chemotherapy (NIPEC). Prospective data regarding pharmacokinetics, survival and adverse events were accumulated. RESULTS Six consecutive patients were treated. Three to 6 one-week long cycles of normothermic intraperitoneal paclitaxel were administered through an intraperitoneal port. No systemic chemotherapy was given. Pharmacokinetic studies were performed on 5 patients. Four patients are free of disease at 8, 13, 18, and 19 years and two patients died of disease 15 years after definitive treatment. Three of 6 patients had a grade III/IV adverse event related to intraperitoneal chemotherapy administration through a port. CONCLUSIONS The small number of patients treated with repeated doses of intraperitoneal paclitaxel cause these data to be interpreted with caution. However, the long-term benefit and favorable pharmacology of these patients suggests the need for further study. Adverse events from this intraperitoneal port were recorded in half of the patients.

Abstract
BACKGROUND and purpose: For gastric cancer patients with peritoneal metastasis (GCPM), there is no universally accepted prognostic staging system. This study aimed to validate the predictive ability of the 15th peritoneal metastasis staging system (P1abc) of the Japanese Classification of Gastric Carcinoma (JCGC). METHODS The data of 309 GCPM patients from July 2007 to July 2017 were retrospectively analyzed. This study compared the prognosis prediction performances of P1abc, the previous JCGC PM staging (P123) and Gilly staging systems. RESULTS The survival curve revealed a significant difference in overall survival (OS) predicted by P1abc, P123 and Gilly staging (all P < 0.05), and the survival of the two adjacent substages were well distinguished by P1abc but not by P123 and Gilly staging. Both P123 and Gilly staging were substituted with P1abc staging in a 2-step multivariate analysis. The results showed that P1abc staging was superior to both P123 and Gilly staging in its discriminatory ability (C-index), predictive accuracy (AIC) and predictive homogeneity (likelihood ratio chi-square). A stratified analysis by different therapies indicated that for the P1a and P1b patients, OS following palliative resection combined with palliative chemotherapy (PRCPC) was better than that after palliative resection (PR) or palliative chemotherapy (PC) alone (P < 0.05). For the P1c patients, OS after receiving PC was significantly superior to that after receiving PRCPC or PR (P = 0.021). CONCLUSION P1abc staging is superior to P123 and Gilly staging in predicting the survival of GCPM patients. Surgeons can provide these patients with appropriate treatment options according to the corresponding substages within P1abc.

Abstract
Objective Intraperitoneal (IP) chemotherapy through subcutaneous port is an effective treatment for gastric cancer (GC) patients with peritoneal metastasis (PM). The objective of this study is to assess the port complications and risk factors for complications in GC patients with PM. Methods In retrospective screening of 301 patients with subcutaneous ports implantation, 249 GC patients with PM who received IP chemotherapy were screened out for analysis. Port complications and risk factors for complications were analyzed. Results Of the 249 analyzed patients, 57 (22.9%) experienced port complications. Subcutaneous liquid accumulation (42.1%) and infection (28.1%) were the main complications, and other complications included port rotation (14.1%), wound dehiscence (12.3%), inflow obstruction (1.7%) and subcutaneous metastasis (1.7%). The median interval between port implantation and occurrence of complications was 3.0 months. Eastern Cooperative Oncology Group (ECOG) performance status [odds ratio (OR), 1.74; 95% confidence interval (95% CI), 1.12−2.69], albumin (OR, 3.67; 95% CI, 1.96−6.86), implantation procedure optimization (OR, 0.33; 95% CI, 0.18−0.61) and implantation groups (OR, 0.37; 95% CI, 0.20−0.69) were independent risk factors for port complications (P<0.05). ECOG performance status was the only factor that related to the grades of port complications (P=0.016). Conclusions Port complications in GC patients who received IP chemotherapy are manageable. ECOG performance status, albumin, implantation procedure and implantation group are independent risk factors for port complications in GC patients with PM.

Abstract
Objective Systemic chemotherapy has limited efficacy in the treatment of peritoneal metastasis (PM) in gastric cancer (GC). Hyperthermic intraperitoneal chemotherapy (HIPEC) combined with complete cytoreductive surgery (CRS) has shown promising outcomes but remains controversial. The present study aimed to evaluate the safety and efficacy of HIPEC without CRS in GC patients with PM. Methods This retrospective propensity score-matched multicenter cohort study included GC patients with PM treated with either chemotherapy alone (Cx group) or with HIPEC combined with chemotherapy (HIPEC-Cx group) in four Chinese high-volume gastric medical centers between 2010 and 2017. The primary outcomes were median survival time (MST) and 3-year overall survival (OS). Propensity score matching was performed to compensate for controlling potential confounding effects and selection bias. Results Of 663 eligible patients, 498 were matched. The MST in the Cx and HIPEC-Cx groups was 10.8 and 15.9 months, respectively [hazard ratio (HR)=0.71, 95% confidence interval (95% CI), 0.58−0.88; P=0.002]. The 3-year OS rate was 10.1% (95% CI, 5.4%−14.8%) and 18.4% (95% CI, 12.3%−24.5%) in the Cx and HIPEC-Cx groups, respectively (P=0.017). The complication rates were comparable. The time to first flatus and length of hospital stay for patients undergoing HIPEC combined with chemotherapy was longer than that of chemotherapy alone (4.6±2.4 dvs. 2.7±1.8 d, P<0.001; 14.2±5.8 dvs. 11.4±7.7 d, P<0.001), respectively. The median follow-up period was 33.2 months.
Conclusions Compared with standard systemic chemotherapy, HIPEC combined with chemotherapy revealed a statistically significant survival benefit for GC patients with PM, without compromising patient safety.

Abstract
Introduction: Peritoneal metastases of cancer remain a major cause of an adverse outcome and death following surgical treatment of malignancies that occur within the abdomen and pelvis. The administration of a chemotherapy solution directly into the peritoneal space has been used to improve the survival in this group of patients.Areas covered: Relevant manuscripts from my own publications and identified through Medline and PubMed were reviewed if they concerned neoadjuvant intraperitoneal and systemic chemotherapy (NIPS), hyperthermic intraperitoneal chemotherapy (HIPEC), early postoperative intraperitoneal chemotherapy (EPIC), normothermic intraperitoneal chemotherapy (NIPEC). The pharmacologic information that will impact on the efficacy of intraperitoneal chemotherapy administration was also reviewed.Expert opinion: The four major technologies for obtaining peritoneal access of cancer chemotherapy to peritoneal metastases were studied. The differences in distribution of chemotherapy solution, in selection of chemotherapy agents to be delivered, and variations in delivery systems were presented and critically analyzed. The most obvious benefits of combined cytoreductive surgery and intraperitoneal chemotherapy have been demonstrated with appendiceal mucinous neoplasms and malignant peritoneal mesothelioma. Continued efforts with new intraperitoneal chemotherapy agents and methods of drug delivery continue for ovarian cancer, colorectal cancer, and gastric cancer.

Abstract
The prognosis of stage IV gastric cancer (GC) is poor, with palliative chemotherapy remaining the main therapeutic option. Studies increasingly indicate that patients with unresectable stage IV GC, who undergo gastrectomy with radical intention after responding to several regimens of combined chemotherapy, can achieve good survival outcomes. Thus, surgery aiming at radical resection for unresectable stage IV GC after combined chemotherapy has received increasing attention in recent years. This novel therapeutic strategy was defined as conversion surgery in patients with unresectable stage IV GC and it can associate with significant improved survival when R0 resection can be achieved. Despite the recent advances in conversion surgery for patients with unresectable stage IV GC, selection criteria for combination chemotherapy regimens, indications for conversion surgery, optimal timing to surgery, and postoperative chemotherapy all remain controversial. This article reviews the current state of conversion surgery for unresectable stage IV GC.

Gastric Cancer 2019; 22:1143-1152. [PMID: 31055693 DOI: 10.1007/s10120-019-00967-3] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2019] [Accepted: 04/25/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Although peritoneal lavage cytology often serves as a sensitive method to detect free cancer cells in the abdominal cavity, some patients experience peritoneal recurrence despite negative cytology. The aim of this study was to evaluate mRNAs in peritoneal lavage fluid as potential markers for predicting the peritoneal recurrence of gastric cancer (GC). METHODS Peritoneal lavage fluid samples were obtained during surgery conducted on 187 patients with GC and from 30 patients with non-malignant disease (controls). The mRNA levels of nine candidate markers were quantified, and analysis of a receiver-operating characteristic curve compared their accuracies. The cutoff was defined as the highest value of the controls. RESULTS Synaptotagmin XIII (SYT13) and carcinoembryonic antigen (CEA) mRNA levels were analyzed further. SYT13 levels were significantly associated with shorter peritoneal recurrence-free survival (PRFS) and overall survival. Among patients with negative peritoneal lavage cytology, those positive for either SYT13 or CEA mRNA experienced significantly shorter peritoneal recurrence-free survival compared with those with negative fluid (hazards ratio [HR] 4.21, P = 0.0114; HR 3.53; P = 0.0426, respectively). Univariate analysis revealed that SYT13 and CEA mRNA levels were significant predictors of peritoneal recurrence. Positive levels of both SYT13 and CEA mRNA demonstrated the highest HR for peritoneal recurrence (HR 12.27, P = 0.0064). Multivariable analysis revealed that SYT13 positivity was a significant independent prognostic factor (HR 3.69; 95% confidence interval, 1.18-12.74; P = 0.0246). CONCLUSIONS Combined measurement of SYT13 and CEA mRNA levels in peritoneal lavage fluid could serve as a promising approach to predict peritoneal recurrence of GC.

Abstract
Recent developments in diagnostic technology, accumulated clinical effort and established evidence have boosted early detection and drastically improved early and long-term outcomes of gastric cancer. However, gastric cancer continues to be one of the most aggressive and life-threatening malignancies among all cancers and is a global health problem. Between January 2017 and December 2018, various fascinating reports of managements and research were published, including the new 15th Japanese Classification of Gastric Carcinoma reflecting the 8th American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) tumor, node and metastasis (TNM) classification (October 2017) and the new Gastric Cancer Treatment Guidelines version 5 (January 2018). Moreover, pivotal molecular features of gastric cancer were clarified by the worldwide cancer genome project, and various treatment targets and biomarkers such as circulating DNAs and microRNAs were detected. Novel treatment options using programmed cell death protein 1 immune checkpoint inhibitors have been started. In this review, we summarize the recent topics of classification, guidelines, and clinical and basic research in order to bring new insights to gastric cancer treatment.

Abstract
Introduction: People with metastatic gastric cancer (GC) have a poor prognosis. The study aims to investigate the efficacy of multi-modality treatment for patients with metastatic GC. Methods: We retrospectively identified 267 patients with stage IV gastric cancer who were treated with systemic chemotherapy: 114 received multi-modality treatments, 153 received systematic chemotherapy alone. The survival of these two groups was compared by log rank test, the independent prognostic factors were investigated using univariate and multivariate analyses. Results: The median survival of metastatic GC patients who received multi-modality treatment was significantly longer than those who received systematic chemotherapy alone (18.4 vs. 11.4 months, P < 0.001). Multivariate analysis identified tumor histologic differentiation, CA19–9 level, previous curative resection, palliative gastrectomy, and metastasectomy as independent prognostic factors for overall survival. In the multimodality treatment group, patients who received palliative gastrectomy or metastasectomy had a longer survival than those who only received intraperitoneal chemotherapy or radiotherapy (21.6 vs. 15.2 months, P = 0.014). Conclusion: Multi-modality treatments offer a survival benefit for patients with metastatic GC. Future prospective studies are needed to confirm the result.

Abstract
OBJECTIVE This study aimed to conduct a genomewide transcriptomic profiling to develop a microRNA (miRNA)-based signature for the identification of peritoneal metastasis (PM) in patients with gastric cancer (GC). SUMMARY BACKGROUND DATA Even though PM in patients with GC has long been recognized to associate with poor prognosis, currently there is lack of availability of molecular biomarkers for its robust diagnosis. METHODS We performed a systematic biomarker discovery by analyzing miRNA expression profiles in primary tumors from GC patients with and without PM, and subsequently validated the expression of candidate miRNA biomarkers in 3 independent clinical cohorts of 354 patients with advanced GC. RESULTS Five miRNAs (miR-30a-5p, -134-5p, -337-3p, -659-3p, and -3917) were identified during the initial discovery phase; three of which (miR-30a-5p, -659-3p, and -3917) were significantly overexpressed in the primary tumors from PM-positive patients in the testing cohort (P = 0.002, 0.04, and 0.007, respectively), and distinguished patients with versus without peritoneal metastasis with the value of area under the curve (AUC) of 0.82. Furthermore, high expression of these miRNAs also associated with poor prognosis (hazard ratio = 2.18, P = 0.04). The efficacy of the combination miRNA signature was subsequently validated in an independent validation cohort (AUC = 0.74). Finally, our miRNA signature when combined together with the macroscopic Borrmann's type score offered a much superior diagnostic in all 3 cohorts (AUC = 0.87, 0.76, and 0.79, respectively). CONCLUSIONS We have established an miRNA-based signature that have a potential to identify peritoneal metastasis in GC patients.

Abstract
BACKGROUND Gastric cancer (GC) patients with positive peritoneal lavage cytology (CY1) and/or localized peritoneum metastasis (P1a) are defined as stage IV in the 15th edition of the Japanese Classification of Gastric Cancer. In Japan, the most common treatment for patients with CY1 and/or P1a is gastrectomy followed by postoperative chemotherapy. PATIENTS AND METHODS Subjects in this multi-institutional retrospective study were GC patients with CY1 and/or P1a who received surgical resection that leaves no macroscopically visible disease. Patients were selected from 34 institutions in Japan between 2007 and 2012. Selection criteria included adenocarcinoma, no distant metastasis except CY1 and P1a, and no prior treatment for GC before surgery. RESULTS Among 824 patients registered, 506 were identified as eligible, with a background of P0CY1, P1aCY0, or P1aCY1 (72.5%, 16.0%, and 11.5% of subjects, respectively). Sixty-two patients had not received postoperative chemotherapy (no-Cx), whereas 444 patients had received postoperative chemotherapy: S-1 monotherapy (S-1; n = 267, 52.7%), cisplatin plus S-1 (CS; n = 114, 22.5%), and others (n = 63, 12.6%). Overall survival (OS) was 29.5, 24.7, 25.4 and 9.9 months in the S-1, CS, 'others', and no-Cx groups, respectively [CS vs. S-1: hazard ratio (HR) 1.15, 95% confidence interval (CI) 0.89-1.50; p = 0.275]. In multivariate analysis, OS was similar between the S-1 and CS groups (CS vs. S-1: HR 1.19, 95% CI 0.92-1.55; p = 0.18). CONCLUSIONS Postoperative chemotherapy after gastrectomy that leaves no macroscopically visible disease may have some survival benefits for GC patients with CY1 and/or P1a. In contrast, S-1 plus cisplatin seems to have no additional benefit over S-1 treatment alone.

Phase I Study of Intraperitoneal Administration of Paclitaxel Combined with S-1 Plus Cisplatin for Gastric Cancer with Peritoneal Metastasis. Oncology 2019; 98:48-52. [PMID: 31487733 DOI: 10.1159/000502484] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Accepted: 08/05/2019] [Indexed: 11/19/2022]
Abstract
INTRODUCTION Intraperitoneal (IP) chemotherapy is a promising treatment option for gastric cancer (GC) with peritoneal metastasis (PM). Recently, superiority of IP administration of paclitaxel (PTX) combined with S-1 and intravenous PTX over conventional systemic chemotherapy was suggested in a phase III study, although the difference in overall survival did not reach statistical significance in the primary analysis. Thus, attempts to combine IP PTX with other systemic therapies with higher efficacy are warranted. We designed a new regimen combining IP PTX with S-1 plus cisplatin (SP), which is regarded as the standard first-line treatment for metastatic GC in Japan, and subsequently carried out a dose-escalation study. METHODS The combination was a 5-weekly regimen. IP PTX was to be administered on days 1, 8, and 22 with an initial dose of 15 mg/m2 at level 1 and 20 mg/m2 at level 2. S-1 was to be administered orally at a fixed dose of 80 mg/m2 b.i.d. for 21 days followed by a -14-day rest. Cisplatin was to be administered intravenously at a dose of 60 mg/m2 on day 8. Dose-limiting toxicities (DLTs) were defined as grade 4 leukopenia, grade 3 (G3) febrile neutropenia, G3 thrombocytopenia, and G3 nonhematological toxicity. RESULTS A total of 9 patients with macroscopic PM were enrolled. No DLTs were observed among the 3 patients at level 1 and 6 patients at level 2. No adverse events or technical problems associated with the IP administration were observed. Consequently, the maximum-tolerated dose was not reached, and the dose for further clinical trials of IP PTX was determined as 20 mg/m2. As for efficacy, peritoneal lavage cytology turned negative after the first course in 4 of 7 patients who had positive cytology before treatment. CONCLUSION The present study determined the dose for further clinical trials of IP PTX to be 20 mg/m2, when combined with the 5-weekly SP regimen.

Abstract
In patients with gastric cancer (GC), peritoneal recurrence is a common risk and associated with poor prognosis. A novel biomarker for the prediction of high-risk peritoneal recurrence in patients with GC is desirable. The present study investigated the effectiveness of exosome-encapsulated microRNAs (ex-miRNAs) as minimally invasive biomarkers in patients with GC that received curative surgery. Recurrence-specific ex-miRNAs were selected following comparison of miRNA microarray data from patients with TNM stage II GC with peritoneal recurrence (n=3) and without peritoneal recurrence following curative surgery (n=3), and three healthy volunteers. In this analysis, exosome-encapsulated miRNA-21 (ex-miR-21) and exosomal miR-92a (ex-miR-92a) exhibited the greatest alterations in expression patterns. Using plasma exosome samples collected from another 129 patients with stage II and III GC, the present study investigated the potential value of ex-miR-21 and ex-miR-92a as biomarkers. Ex-miRNA levels were measured using TaqMan miRNA assays. Ex-miR-21 levels were significantly higher and ex-miR-92a levels were significantly lower in samples from patients with GC compared with healthy controls. The overall survival (OS) and peritoneal recurrence-free survival (PRFS) were poorer in stage II and III patients with high ex-miR-21 levels than in patients with low miR-21 levels. OS and PRFS of stage II and III patients with low ex-miR92a levels were significantly worse than those with high ex-miR92a levels. Cox multivariate analyses indicated that ex-miR-21 and ex-miR-92a were independent prognostic factors for OS and PRFS in stage II and III GC. A negative correlation was detected between expression levels of miR-21 and programmed cell death protein 4 mRNA, and miR-92a and prostaglandin E receptor 4 mRNA. Therefore, ex-miR-21 and ex-miR-92a may function as effective and minimally invasive biomarkers for the prediction of peritoneal recurrence and the prognosis of patients with stage II/III GC.

Abstract
Introduction: Gastric cancer is one of the most common causes of cancer-related mortality worldwide. To improve clinical outcomes, it is critical to develop appropriate approaches to diagnosis and treatment. Biomarkers have numerous potential clinical applications, including screening, assessing risk, determining prognosis, monitoring recurrence, and predicting response to treatment. Furthermore, biomarkers may contribute to the development of effective therapies. Areas covered: Here we review recent progress in exploiting GC-specific biomarkers such as protein-coding genes, microRNAs, long noncoding RNAs, and methylated gene promoters. Expert opinion: The development of biomarkers for diagnosing and monitoring gastric cancer and for individualizing therapeutic targets shows great promise for improving gastric cancer management.

Abstract
Despite decreasing incidence, gastric cancer remains a major health problem worldwide and is associated with poor survival. The poor survival is mainly attributed to delayed presentation which may cause local or systemic metastases. The standard of care for patients with metastatic gastric cancer (MGC) is palliative chemotherapy with best supportive care. Although the survival has improved owing to advances in chemotherapeutic agents, it is still unsatisfactory, and some perspective changes are needed in the management of MGC to improve the outcomes. Therefore, various alternative treatment strategies for MGC have formed the most important research topics. Liver-directed treatment (LDT) options such as liver resection, radiofrequency ablation (RFA), microwave ablation (MWA), and hepatic artery infusion chemotherapy (HAIC) have been studied in the management of liver metastasis from gastric cancer (LMGC). Intraperitoneal chemotherapy (IPC) in addition to cytoreductive surgery (CRS) aiming to remove all macroscopic tumor focus resulting from peritoneal dissemination is the treatment option for peritoneal metastasis, while para-aortic lymph node dissection is the treatment option for para-aortic lymph node metastasis which is considered to be M1 disease. Conversion surgery is a novel concept aiming at R0 resection for originally unresectable or marginally resectable tumors after a remarkably good response to the chemotherapy. Large amounts of data in the literature have demonstrated the benefits of individualized approaches such as the combination of systemic and local treatment options in selected patient groups. In this review, we aimed to explore the current and future treatment options by reviewing the literature on this controversial topic.

Abstract
Meckel’s diverticulum is an outpouching of the distal small bowel. This diverticulum may contain ectopic gastric epithelium which can become malignant. A patient with gastric cancer with peritoneal metastases had the cancer origin in a Meckel’s diverticulum. Systemic cancer chemotherapy followed by cytoreductive surgery provided 4 years of disease-free survival.
Background Meckel’s diverticulum is the most common congenital anomaly of the gastrointestinal tract, resulting from incomplete obliteration of the omphalomesenteric duct in early fetal development. The diverticulum frequently contains ectopic gastrointestinal epithelial tissue, most commonly gastric or pancreatic. Adenocarcinoma can arise from either of these epithelia but is extremely rare, with less than 50 cases reported in the world literature. Methods In a patient with peritoneal metastases from ectopic gastric mucosae in a Meckel’s diverticulum a multidisciplinary treatment plan was initiated. Results Diagnosis was evident from study of the resected specimen of small bowel in a patient with acute abdominal pain. A multiagent chemotherapy regimen using oxaliplatin, mitomycin C, doxorubicin, and capecitabine (O-Max) resulted in a clinical and radiologic response. A second surgery with extensive sampling of tissues from the abdomen and pelvis confirmed a complete response to systemic chemotherapy. At four years from onset of disease the patient has no evidence of recurrence. Conclusions Peritoneal metastases from malignant degeneration of ectopic gastric epithelium in a Meckel’s diverticulum was reported. Multidisciplinary treatments were beneficial.

Abstract
BACKGROUND There is no standard first-line chemotherapy for advanced gastric cancer with severe peritoneal metastasis. Although fluoropyrimidine is often used, its efficacy is limited, and it remains unclear whether combination therapy with platinum improves clinical outcomes. METHODS This retrospective study involved patients at six Japanese academic hospitals between 2010 and 2016. Patients with advanced gastric cancer and severe peritoneal metastasis were included if they had massive ascites and/or inadequate oral intake requiring intravenous nutritional support. We then compared the efficacy and safety of fluoropyrimidine monotherapy with those of fluoropyrimidine/platinum combination therapy. RESULTS Compared with the combination therapy group (n = 64), the monotherapy group (n = 65) had worse general health (more patients with elderly age, performance status > 2, and having both massive ascites and inadequate oral intake). Both overall survival (9.0 vs 5.0 months, p < 0.01) and progression-free survival (4.3 vs 2.3 months, p < 0.01) were significantly longer in the combination group, and the significance remained after adjusting for prognostic variables (hazard ratios of 0.47 and 0.41, respectively; p < 0.01). Improvements in ascites and oral intake were also greater in the combination group. Although neutropenia (grade ≥ 3) occurred more frequently with combination therapy, both treatments in this study were tolerable. CONCLUSIONS Combination therapy with fluoropyrimidine and platinum might be more effective than monotherapy with fluoropyrimidine and was tolerable for patients with advanced gastric cancer and severe peritoneal metastasis.

Abstract
INTRODUCTION Gastric cancer with peritoneal metastasis has a poor outcome. Only a few studies have specifically investigated this group of patients. Japanese researchers have shown that chemotherapy with intraperitoneal paclitaxel (IPP) and oral S-1 (tegafur/gimeracil/oteracil) is active and well tolerated. These results have been achieved in a specific genetic pool (Japanese population), using regimens that may not be available in other parts of the world. We have designed this phase I trial to investigate IPP in combination with a standard chemotherapy combination in these patients. METHODS We use a 3+3 expanded cohort dose escalation until a predefined number of dose-limiting toxicities are reached. Patients will have an intraperitoneal catheter placed surgically after trial enrolment. Chemotherapy includes a maximum of six cycles (21 days) of capecitabine (X) (1000 mg/m2 two times a day, days 1-14)+cisplatin (C) (intravenous 80 mg/m2 day 1) and IPP (days 1 and 8) with the following doses: cohort-1: 10 mg/m2, cohort-2: 20 mg/m2 and cohort-3: 30 mg/m2. Primary endpoint is to determine the maximum tolerated dose of IPP. Secondary endpoints include determining the safety and tolerability of IPP in combination with C and X, overall response rates, ascites response rate, progression-free survival, overall survival and effects on quality of life.Important inclusion criteria include age ≥18 years, human epidermal growth factor receptor 2 non-amplified gastric adenocarcinoma with histological or cytology-proven peritoneal involvement and adequate organ function. Exclusion criteria include previous malignancy within 5 years, recent abdominal or pelvic radiation treatment, significant abdominal adhesions or sepsis. ETHICS AND DISSEMINATION The study is approved by Southern Adelaide Clinical Human Research Ethics Committee. A manuscript will be prepared for publication on the completion of the trial. This study will be conducted according to the Note for Guidance on Good Clinical Practice (CPMP/ICH/135/95) annotated with TGA comments (Therapeutic Goods Administration DSEB July 2000) and in compliance with applicable laws and regulations. The study will be performed in accordance with the NHMRC Statement on Ethical Conduct in Research Involving Humans (© Commonwealth of Australia 2007), and the NHMRC Australian Code for the Responsible Conduct of Research (©Australian Government 2007), and the principles laid down by the World Medical Assembly in the Declaration of Helsinki 2008.
