J Gastric Cancer 2020; 20:233-244. [PMID: 33024580 PMCID: PMC7521980 DOI: 10.5230/jgc.2020.20.e20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2020] [Revised: 04/16/2020] [Accepted: 05/01/2020] [Indexed: 11/29/2022] Open
Abstract
Purpose For unresectable or initially metastatic gastric cancer, conversion surgery (CVS), after systemic chemotherapy, has received attention as a treatment strategy. This study evaluated the prognostic value of ypTNM stage and the oncologic outcomes in patients receiving CVS. Materials and Methods A retrospective review of clinicopathologic findings and oncologic outcomes of 116 patients who underwent CVS with curative intent, after combination chemotherapy, between January 2000 and December 2015, has been reported here. Results Twenty-six patients (22.4%) underwent combined resection of another organ and 12 patients received para-aortic lymphadenectomy (10.3%). Pathologic complete remission (CR) was confirmed in 11 cases (9.5%). The median overall survival (OS) and disease-free survival (DFS) times were 35.0 and 21.3 months, respectively. In multivariate analysis, ypTNM stage was the sole independent prognostic factor for DFS (P=0.042). Tumors invading an adjacent organ or involving distant lymph nodes showed better survival than those with peritoneal seeding or solid organ metastasis (P=0.084). Kaplan-Meier curves showed that the 3-year OS rate of patients with pathologic CR and those with CR of the primary tumor but residual node metastasis was 81.8% and 80.0%, respectively. OS was 65.8% for stage 1 patients, 49.8% for those at stage 2, and 36.3% for those at stage 3. Conclusions The ypTNM staging is a significant prognostic factor in patients who underwent CVS for localized unresectable or stage IV gastric cancers. Patients with locally advanced but unresectable lesions or with tumors with distant nodal metastasis may be good candidates for CVS.

Li S, Zang L. The Effectiveness of Gastrectomy With Chemoradiotherapy Among Stage IV Gastric Adenocarcinoma: A Population-Based Analysis. Front Oncol 2020; 10:630. [PMID: 32411605 PMCID: PMC7198747 DOI: 10.3389/fonc.2020.00630] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2019] [Accepted: 04/06/2020] [Indexed: 12/18/2022] Open
Abstract
Objectives: The strategy for the treatment of stage IV gastric cancer remains controversial. The objective of this study was to assess whether tumor resection is beneficial to survival in gastric cancer patients with incurable stage IV disease. Methods: This is a retrospective cohort study of gastric cancer patients in the Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2015. Due to the baseline bias, 1:1 propensity score matching (PSM) was used in this cohort. Patients were grouped by treatment, (1) gastrectomy with chemoradiotherapy (CRT), or (2) CRT only, and a Cox proportional hazards regression model was used to identify predictors of survival. Overall survival was compared between the two groups using the Kaplan-Meier method. Result: After propensity score matching, 162 stage IV gastric cancer patients diagnosed from 2010 to 2015 were identified. Among these patients, half underwent gastrectomy with CRT, while the others received CRT only. The median overall survival rates were 22 months from the date of surgery for the gastrectomy with CRT group and 9.0 months for CRT only group. In the multivariable Cox regression analysis, surgery was associated with a significant improvement in overall survival [hazard ratio (HR) of death = 0.31, 95% confidence interval (CI) = 0.21-0.46, P < 0.0001]. Conclusion: In conclusion, stage IV gastric cancer is still a fatal disease. This population-based study found that compared with CRT alone, CRT with gastrectomy may be associated with a survival benefit in patients with metastatic GC. In selected patients' survival can be prolonged when the primary tumor is removed. Prospective, randomized trials are required to determine the best strategy for metastatic GC and to describe the characteristics of the selected patients.

Abstract
BACKGROUND With advances in gastric cancer chemotherapy, conversion surgery has drawn attention as a new strategy to improve the outcome of stage IV disease. We investigated the efficacy of conversion surgery following chemotherapy for patients with stage IV gastric cancer. METHODS We retrospectively reviewed clinico-pathologic variables and oncologic outcomes for 101 patients with stage IV gastric cancer who were treated with systemic chemotherapy followed by gastrectomy with intension of curative resection from January 2005 to December 2012. RESULTS In terms of the best response from palliative chemotherapy, complete or partial response were observed in 65 patients (64.4%) in overall. Complete response of metastatic site were observed in 72 (71.3%) and 66 (65.3%) patients as best and pre-operative response, respectively. The overall complete macroscopic resection, rate was 56.4%. Eleven patients (10.9%) received combined metastasectomy. There was no postoperative surgery-related mortality for 1 month. The median overall survival time was 26.0 months. Multivariable analysis identified complete macroscopic resection, chemotherapy response (complete response/partial response) of metastatic sites, and change in CEA level as independent prognostic factors contributing to overall survival. CONCLUSIONS Patients with stage IV gastric cancer who exhibit a good clinical response to chemotherapy might obtain greater survival benefit from gastrectomy following chemotherapy compared with patients who exhibit a poor response to chemotherapy. Prospective, randomized trials are required to determine the best strategy for combining initial chemotherapy with subsequent gastrectomy.

Overexpression of MMP21 and MMP28 is associated with gastric cancer progression and poor prognosis. Oncol Lett 2018; 15:7776-7782. [PMID: 29731903 PMCID: PMC5920775 DOI: 10.3892/ol.2018.8328] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2015] [Accepted: 01/25/2018] [Indexed: 12/18/2022] Open
Abstract
Matrix metalloproteinase (MMP)-21 and MMP-28, or epilysin, are overexpressed during the invasion and metastasis of solid tumors. The present study investigated MMP-21 and MMP-28 expression levels in human gastric cancer using tissue microarray (TMA) analysis, and determined their association with clinicopathological characteristics and patient prognosis. TMA blocks, including 436 cases of gastric cancer and 92 non-cancerous adjacent gastric tissues, were investigated using immunohistochemistry. Staining results were analyzed statistically in association with various clinicopathological characteristics and overall survival. The MMP-21 and MMP-28 positive detection rate was 31.9% (139/436) and 34.4% (150/436), respectively, in the gastric carcinoma tissue specimens. MMP-21 and MMP-28 expression levels were negative in the 92 normal gastric tissue samples. In patients with gastric cancer, positive expression of MMP-21 and MMP-28 was correlated with tumor diameter, depth of invasion, vessel invasion, lymph node and distant metastases and tumor-node-metastasis stage. The overall survival rate was significantly lower in MMP-21 and MMP-28-positive compared with negative patients. Cox multivariate analysis revealed that MMP-21 and MMP-28 levels were independent predictors of survival in patients with gastric cancer. These findings emphasize the importance of MMP-21 and MMP-28, which may serve as novel and independent prognostic markers for the invasion and metastasis of human gastric cancer.

Abstract
PURPOSE A triplet regimen of docetaxel, cisplatin, and S-1(DCS) is highly effective against metastatic gastric cancer. We performed this study to clarify the safety and efficacy of surgical resection in patients with initially unresectable gastric cancer, after down-staging or disease control was achieved by DCS chemotherapy. METHODS The subjects of this retrospective study were 31 consecutive patients with initially unresectable gastric cancer, who underwent surgical resection between October, 2006 and December, 2012, after down-staging or disease control was achieved by DCS chemotherapy. We evaluated the clinicopathological factors and clinical outcomes and assessed radiographic response based on the RECIST criteria, not by central review. RESULT Before DCS chemotherapy, 18 patients had extra-regional lymph node metastasis, 5 had liver metastasis, 8 had macroscopic peritoneal metastasis, and 8 had pancreatic head invasion. Twenty-three (74.2%) of the 31 patients underwent R0 resection. Postoperative morbidity and mortality rates were 16.1 and 0%. During chemotherapy, grade 3/4 toxicities included neutropenia (54.8%), leukopenia (32.3%), and anemia (16.1%). Median progression-free survival and median overall survival (OS) were 42.1 and 56.1 months, respectively. These results were similar for all patients, except those with locally advanced disease alone. In the multivariate analysis for OS, ypN remained an independent negative prognostic factor (p = 0.018). CONCLUSION Surgical resection after DCS chemotherapy for initially unresectable gastric cancer was safe and provided a reasonable R0 resection rate and good mid-term survival.

Abstract
BACKGROUND Gastric cancer is one of the most common cancers. Unfortunately, it is often diagnosed at the advanced stage International Union Against Cancer stage IV. This induced us to carry out an interdisciplinary analysis of this patient group with the Department of Internal Medicine 1. Our aim was to discuss cancers classified initially as unresectable in a meeting of the interdisciplinary tumor board after palliative chemotherapy, and to refer selected patients for surgery after establishing resectability. The outcome of the chemotherapy, operation method, complication rate, and long-term survival were analyzed. METHODS From 1999 to 2008, 76 patients with metastatic gastric cancer or carcinoma of the esophagogastric junction were discussed by the interdisciplinary tumor board of the University of Erlangen and classified initially as unresectable. The patients then received palliative chemotherapy according to the AIO regimen (weekly high-dose 5-fluorouracil/folinic acid [FU/FA] in a 24 h infusion), plus irinotecan. If the tumor was subsequently classified as resectable, the patient underwent either gastric resection or gastrectomy with DII-III dissection. Metastases were resected depending on their location (liver). Peritoneal carcinomatosis was treated additionally by HIPEC. Statistical analysis was with SPSSS version 20. RESULTS Surgical and general complications and hospital mortality were acceptable. There were no cases of anastomotic leak, but one patient died of fulminant pneumonia. The R0 resection rate was 69 %, and four patients had long-term survival of more than 60 months. There were significant survival advantages. CONCLUSIONS Metastatic gastric cancer or carcinoma of the esophagogastric junction can become resectable after downsizing the tumor with palliative chemotherapy. Long-term survival is achieved in some cases. Therefore, every patient with this type of cancer should be discussed by the interdisciplinary tumour board after palliative chemotherapy to provide him with a chance of cure after re-evaluation.
