The value of noncurative resection for patients with gastric cancer with single peritoneal metastasis is still debatable. This study was undertaken to evaluate the survival benefit of resection in those patients. From 2006 to 2009, 119 patients with gastric cancer with single peritoneal metastasis were identified during surgery. Sixty-three of them had noncurative resection; the remainder had nonresection. Clinicopathological variables and survival were analyzed. Overall survival of patients in the noncurative resection group was longer than that in the nonresection group (14.869 vs 7.780 months). This survival advantage was still significantly better in the P1/P2 patients who underwent noncurative resection (mean survival time 21.164 vs 7.636 months, P = 0.001), but not in the P3 group ( P = 0.489). Multivariate analysis indicated that only noncurative resection retained a significant association with better prognosis in P1/P2 patients. The perioperative mortality rate in the resection group was not significantly higher than that of the noncurative group ( P = 0.747). Noncurative resection can prolong the survival of patients with gastric cancer with single P1/P2 peritoneal metastasis. This surgical approach should not be taken into account for those patients with P3 gastric cancer.

Purpose: To evaluate the survival benefit of adjuvant chemotherapy after curative resection in serosa-negative gastric cancer patients (excluding patients who were T1N0), we conducted a multicenter phase III clinical trial in which 13 cancer centers in Japan participated. Patients and Methods: From January 1993 to December 1994, 252 patients were enrolled into the study and allocated randomly to adjuvant chemotherapy or surgery alone. The chemotherapy comprised intravenous mitomycin 1.33 mg/m2, fluorouracil (FU) 166.7 mg/m2, and cytarabine 13.3 mg/m2 twice weekly for the first 3 weeks after surgery, and oral FU 134 mg/m2 daily for the next 18 months for a total dose of 67 g/m2. The primary end point was relapse-free survival. Overall survival and the site of recurrence were secondary end points. Results: Ninety-eight percent of patients underwent gastrectomy with D2 or greater lymph node dissection. There were no treatment-related deaths and few serious adverse events. There was no significant difference in relapse-free and overall survival between the arms (5-year relapse-free survival 88.8% chemotherapy v 83.7% surgery alone; P = .14 and 5-year survival 91.2% chemotherapy v 86.1% surgery alone; P = .13, respectively). Nine patients (7.1%) in the chemotherapy arm and 17 patients (13.8%) in the surgery-alone arm had cancer recurrence. Conclusion: There was no statistically significant relapse-free or overall survival benefit with this adjuvant chemotherapy for patients with macroscopically serosa-negative gastric cancer after curative resection, and there was no statistical difference between the two arms relating to the types of cancer recurrence. We do not recommend adjuvant chemotherapy with this regimen for this population in clinical practice.

Hyperprogressive Disease

BackgroundNivolumab showed a survival benefit for advanced gastric cancer (AGC). However, an acceleration of tumour growth during immunotherapy, (hyperprogressive disease, HPD) has been reported in various cancers. This study reviewed the HPD in patients with AGC treated with nivolumab or irinotecan.MethodsThe subjects of this retrospective study were patients with AGC with measurable lesions, and their tumour growth rates (TGR) during nivolumab or irinotecan were compared with those during prior therapy. HPD was defined as an increase in TGR more than twofold.Results34 and 66 patients received nivolumab and irinotecan in third or later line between June 2009 and September 2018 at our hospital; 22 patients receiving nivolumab had prior treatment with irinotecan, and one patient received irinotecan after nivolumab. Nivolumab and irinotecan showed no differences in disease control rates (38.2% and 34.8%) and in progression-free survival (PFS) (HR 1.1, 95% CI 0.7 to 1.6, p=0.802). The incidence of HPD was slightly higher after nivolumab (29.4%) than after irinotecan (13.5%) (p=0.0656), showing no differences in background between the patients with and without HPD. Compared between HPD and PD other than HPD after nivolumab, the HRs for PFS and overall survival (OS) were 1.1 (95% CI 0.5 to 2.7; p=0.756), and 2.1 (95% CI 0.7 to 5.8; p=0.168), but such clear difference in OS was not observed after irinotecan.ConclusionsHPD was observed more frequently after nivolumab compared with irinotecan, which was associated with a poor prognosis after nivolumab but not so clearly after irinotecan.

215 Background: The purpose of this study is to evaluate significant prognostic factor and compare the cause of death in patients with advanced or recurrent gastric cancer. Methods: We reviewed the medical records of 170 patients who had been diagnosed as advanced or recurrent gastric cancer between January 2006 and September 2013. The patients were divided into two groups. One group (advanced gastric cancer: AC) included 104 patients had undergone chemotherapy for advanced gastric cancer, and the other group (recurrent gastric cancer: RC) 66 for recurrence after surgical treatment. The causes of death and overall survival were compared between two groups, and the significant prognostic factors were investigated by multivariate analysis. Also, subgroup analysis was performed for 18 patients with gastrectomy for curative intent, and they were proved to have unresectable gastric cancer after surgery (non-palliative surgery for advanced gastric cancer: NS). Results: In the comparison for the causes of death, two groups showed no statistical difference, but AC group had more tendency to die because of bleeding ( p = 0.054) and infection ( p = 0.075). Overall survival of AC group did not differ from that of RC ( p = 0.901). In multivariate analysis, bone metastasis ( p = 0.013, HR = 1.923), peritoneal seeding ( p = 0.001, HR = 2.182) and the frequency of chemotherapy ( p < 0.001, HR = 0.887) were significantly associated with the overall survival. In a subgroup analysis, the overall survival of NS was significantly higher than AC ( p = 0.032). Conclusions: In the patients with advanced or recurrent gastric cancer, AC might have more possibility to die because of bleeding and infection than RC. Additionally, the prognosis of patients with advanced or recurrent gastric cancer was affected by the presence of bone metastasis, peritoneal seeding and frequency of chemotherapy. Non-palliative surgery for gastric cancer might show the better prognosis than AC in the specific conditions.

212 Background: Gastric cancer is a prevalent global disease with significant mortality. Nearly 22,220 patients are diagnosed annually in the US, with approximately 50% of them presenting with disease that extends beyond loco-regional confines, and only a small percentage undergoing curative resection. We aim to study the clinical characteristics and survival benefit of surgery in stage IV gastric cancer. Methods: We reviewed the records of all patients diagnosed with gastric cancer in our cancer center from 1999 to 2013. A total of 272 stage IV cases were identified. Demographics, tumor characteristics, treatment modalities (surgical vs. non-surgical) and survival rate were analyzed. Kaplan-Meier was used for survival analysis and Cox regression for univariate and multivariate analysis. Results: Within the cohort 70 (26%) patients received surgery and 202 (74%) were treated with chemotherapy ± radiation. Mean age at diagnosis was 64 years in the surgical (S) patients and 66 years in the non-surgical (NS). Non-Hispanics whites were more likely to receive surgery vs. all other ethnic groups combined, representing 77% vs. 23% of the S subgroup (p<0.0001). Patients with proximal tumors were more likely to receive surgery when compared with distal tumors (37 (53%) vs. 14 (20%), p<0.0001). Total gastrectomy was the most common surgical procedure 33 (47%). There was a significant difference in disease specific survival between the two groups, being 17.3 months for S (95%CI: 11.1-23.4) and 5.3 months for NS (95%CI: 3.8-6.7) (p<0.0001). Age > 70 years (OR: 1.74, p<0.02), proximal tumor location (OR: 0.75, p<0.04), surgery (OR: 0.37, p<0.0001) and extended lymphadenectomy (D2) (OR: 0.26, p<0.02) were independent and significant predictors of survival by multivariate analysis. Conclusions: In our cohort, non-Hispanic whites and patients with proximal tumors were more likely to undergo surgery. A major survival benefit was observed for the surgical subgroup when compared to non-surgical treatment for stage IV gastric cancer. Future research should aim to further elucidate the specific role of surgery, as this could potentially impact management and transform the standard of care in stage IV gastric cancer.

390 Background: Peritoneal metastasis of gastric cancer is relatively common (17%) and is associated with poor survival. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is still controversially discussed, as it has proven an increase in median survival in selected patients, but only a small subgroup reached long-term survival. The aim of this study was to collect and analyze a worldwide cohort of patients treated with CRS and HIPEC with long-term survival in order to explore relevant patient characteristics. Methods: We conducted a questionnaire, which was distributed to all collaborators of the Peritoneal Surface Oncology Group International (PSOGI). Inclusion criteria were: histopathologic proven peritoneal metastasis of gastric cancer, treated with CRS and HIPEC, and overall survival > 5 years. Patient, tumor, and therapeutic details were collected and analyzed. Results: A total of 29 patients with a mean age of 52.5 years and a mean PCI of 3.2 were included. The overall median survival was 11.0 years (min 5.0; max 27.9). The predictors completeness of cytoreduction (CC-0) and low PCI (PCI < 6) were present in 23/29 patients. 13/29 patients developed at a median of 82.2 months tumor recurrence. Tumor recurrence was associated with inferior median overall survival compared to patients without tumor recurrence (8.8 years vs. not reached; p = 0.002). Conclusions: Long-term survival and even cure are possible in patients with peritoneal metastasis of gastric cancer treated with CRS and HIPEC. Completeness of cytoreduction (CC-0) and low PCI seemed to be crucial. Further studies are needed in order to improve existing selection criteria.

End Results

Object Central nervous system (CNS) hemangiopericytomas are relatively uncommon and unique among CNS tumors as they can originate from or develop metastases outside of the CNS. Significant difference of opinion exists in the management of these lesions, as current treatment paradigms are based on limited clinical experience and single-institution series. Given these limitations and the absence of prospective clinical trials within the literature, nationwide registries have the potential to provide unique insight into the efficacy of various therapies. Methods The authors queried the Surveillance Epidemiology and End Results (SEER) database to investigate the clinical behavior and prognostic factors for hemangiopericytomas originating within the CNS during the years 2000–2009. The SEER survival data were adjusted for demographic factors including age, sex, and race. Univariate and multivariate analyses were performed to identify characteristics associated with overall survival. Results The authors identified 227 patients with a diagnosis of CNS hemangiopericytoma. The median length of follow-up was 34 months (interquartile range 11–63 months). Median survival was not reached, but the 5-year survival rate was 83%. Univariate analysis showed that age and radiation therapy were significantly associated with survival. Moreover, young age and supratentorial location were significantly associated with survival on multivariate analysis. Most importantly, multivariate analysis using the Cox proportional hazards model showed a statistically significant survival benefit for patients treated with gross-total resection (GTR) in combination with adjuvant radiation treatment (HR 0.31 [95% CI 0.01–0.95], p = 0.04), an effect not appreciated with GTR alone. Conclusions The authors describe the epidemiology of CNS hemangiopericytomas in a large, national cancer database, evaluating the effectiveness of various treatment paradigms used in clinical practice. In this study, an overall survival benefit was found when GTR was accomplished and combined with radiation therapy. This finding has not been appreciated in previous series of patients with CNS hemangiopericytoma and warrants future investigations into the role of upfront adjuvant radiation therapy.

Cancer Data

The survival benefit of an extended versus standard lymphadenectomy for gastric cancer (GC) is often attributed to upstaging when more lymph nodes (LNs) are removed, i.e., stage migration. An extended lymphadenectomy is defined as 30 or more LNs examined, a surrogate for a D2 dissection. The aim of this study is to examine whether the survival benefit of extended lymphadenectomy persists when stage migration is not possible. The National Cancer Data Base was queried to identify patients with pathologic N3 (pN3, ≥7 positive LNs) gastric adenocarcinoma. Overall survival (OS) was compared by extent of lymphadenectomy (7–14, 15–29, and ≥30 LN) and stratified by Tstage. Of 2101 pN3 patients, 419 (19.9%) had 7 to 14 LNs examined, 1164 (55.4%) had 15 to 29 LNs examined, and 518 (24.7%) had ≥30 LNs examined. Unadjusted three-year OS in the entire cohort was 24.6, 27.3, 30.5 per cent for 7 to 14 LNs, 15 to 29 LNs, and ≥30 LNs, respectively (P = 0.003). On adjusted survival analysis by stage for patients with pT1-T2N3 disease, removing ≥30 LNs significantly improved OS compared with removing 7 to 14 LNs (hazard ratio [HR] 2.45, 95% confidence interval = 1.25–4.82, P = 0.009). Extended lymphadenectomy may confer a survival benefit in select patients with pT1N3 and pT2N3 GC, highlighting the importance of the number of LNs examined rather than stage migration on survival. For the majority of the N3 population, pT3-pT4, the extent of lymphadenectomy did not significantly improve the OS.

120 Background: Endoscopic submucosal dissection (ESD) is now accepted as an alternative to surgery for the treatment of early gastric cancer (EGC). However, long-term clinical outcome of ESD for EGC compared to surgical resection has not been evaluated. The aim of this study is to evaluate the clinical outcome of ESD for EGC compared to surgical resection. Methods: A retrospective analysis was performed in 152 patients who underwent ESD or surgical resection for EGC according to Gotoda’s extended criteria from 2006 and 2008 in Incheon St. Mary’s Hospital and Seoul St. Mary’s Hospital, The Catholic University of Korea. Overall survival and recurrence rates were compared between the two groups. Results: A total of 56 patients underwent surgical gastrectomy and 96 patients underwent ESD. The medial follow-up was 76 months in surgical resection group and 71 months in ESD group. Metachronous recurrences including dysplasia were found in 9 patients in ESD group and none in surgical resection group (P=0.001). There was no significant difference between the groups in overall survival. Conclusions: Gotoda’s extended criteria for ESD might be acceptable for the treatment of EGC considering the oval survival. However, meticulous surveillance program should be established because metachronous recurrence is more common after ESD.

99 Background: Efficacy of 2nd and 3rdline chemotherapy in recurrent gastric cancer with peritoneal metastasis (RGCPM) is limited. We assessed the feasibility, safety and activity of intraperitoneal chemotherapy as PIPAC C/D in RGCPM after > 1 line of intravenous chemotherapy. Methods: Open-label, single-arm, Phase II ICH-GCP Clinical Trial (NCT01854255) Patients were scheduled for 3 courses q42 days of low-dose PIPAC with doxorubicin 1.5 mg/m2 and cisplatin 7.5 mg/m2. Primary endpoint was objective tumor response (RECIST 1.1). Secondary endpoints were safety (CTCAE 4.0), histological tumor regression (PRGS) and overall survival. Results: 25 patients were enrolled. 10/25 (40 %, ITT) patients had an OTR. Complete or major regression on histology was observed in 9/12 (75 %) patients who underwent at least 2 PIPAC cycles. Mean overall survival was 8.4 months (13.1 months in patients with PCI < 12). There were no treatment-related deaths, no grade 4 toxicity and four (16%) grade 3 toxicities. Conclusions: PIPAC C/D is well tolerated and active in patients with RGCPM. Survival is encouraging. Randomized controlled trials should now be designed. Clinical trial information: NCT01854255.
