Liang XQ, Wang Z, Li HT, Ma G, Yu WW, Zhou HC, Liu HB. Indication for endoscopic treatment based on the risk of lymph node metastasis in patients with undifferentiated early gastric cancer. Asian J Surg 2020; 43:973-977. [PMID: 31964584 DOI: 10.1016/j.asjsur.2019.12.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2019] [Revised: 10/30/2019] [Accepted: 12/08/2019] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Despite the risk of lymph node metastasis (LNM), the indications of endoscopic submucosal dissection (ESD) has expanded to undifferentiated type (UD-type) early gastric cancer (EGC). There is debate as to whether the endoscopic resection can be used. This study was conducted to evaluate risk factors for LNM in undifferentiated early gastric cancer, implications for the indication of the ESD so as to providing evidence for proper clinical management for UD-type EGC. METHOD We retrospectively analyzed 203 patients with UD-type EGC who underwent gastrectomy for primary gastric adenocarcinoma between 2012 and 2017. We evaluated the relationship between the clinicopathological factors and the presence of LNM using univariable and multivariable logistic regression analyses. RESULTS A total of 203 UD-type EGC patients were enrolled, and LNM was positive in 40 cases (19.7%). Multivariable logistic regression analysis identified three independent risk factors for LNM, the tumor size (≥2.0 cm, P < 0.001), depth of invasion (P < 0.001), and lymphatic vessel involvement (LVI, P < 0.001). LNM was observed in 5.9% patients without the three predictive factors in UD-type EGC, whereas 7.7% and 37.7% of patients with one and two risk factors had LNM, respectively. In contrast, the LNM rate was up to be 66.7% in patients with three factors. Of 41 patients satisfying the expanded indication of ESD, 3 patients (7.3%) showed LNM. LNM was not found in any of 12 patients with small intramucosal lesions (<1.0 cm) without LVI. CONCLUSIONS LNM-related risk factors were tumor larger than 2.0 cm, submucosal invasion, and the presence of LVI in UD-type EGC. ESD alone may be sufficient treatment for the intramucosal UD-type EGC that is smaller than 1.0 cm in size. When endoscopically resected specimens show unexpectedly larger tumor size, unexpected submucosal and LVI than that determined at pre-ESD endoscopic diagnosis, an additional gastrectomy with lymphadenectomy should be considered.

Updated evaluation of endoscopic submucosal dissection versus surgery for early gastric cancer: A systematic review and meta-analysis. Int J Surg 2020; 73:28-41. [PMID: 31783166 DOI: 10.1016/j.ijsu.2019.11.027] [Citation(s) in RCA: 72] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2019] [Revised: 10/13/2019] [Accepted: 11/17/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND OBJECTIVE Endoscopic resection (ER) has been a standard treatment modality for early gastric cancer with ignorable risks of lymph node metastasis. As for EGCs within expanded indications, endoscopic submucosal dissection (ESD) has considerable advantages over endoscopic mucosal resection (EMR) regarding higher rate of en bloc resection, complete resection, but lower risk of local recurrence. Previous meta-analyses comparing ESD with surgery for EGC are scarce and not robust to reach definitive conclusions. METHODS We searched PubMed, Web of Science, EMBASE, Cochrane Library Databases and Google Scholar through July 2019 to identify studies evaluating ESD vs surgery for EGC. Newcastle-Ottawa Quality Assessment Scale was used to assess the quality of enrolled studies. Patient baseline characteristics, procedure-related and prognosis outcomes, and adverse event data were extracted and pooled for analyses by the Review Manager 5.3 software. Grading of Recommendations Assessment, Development and Evaluation guidelines (GRADE) were used to assess the quality of evidence. Trial Sequential Analysis (TSA) was conducted to weaken random error and enhance the reliability of evidence. RESULTS Totally 18 retrospective studies, involving 5993 patients, were included. ESD benefits were 128.38 min shorter operation duration [95%CI: (-204.68, -52.09), P = 0.001], 7.13 days shorter hospital stay [95%CI: (-7.98, -6.28), P < 0.00001], lower risk of procedure-related death [OR = 0.21, 95%CI: (0.07, 0.68), P = 0.009], lower risk of overall complication [OR = 0.47, 95%CI: (0.34, 0.63), P < 0.00001]. ESD was also associated with lower costs and better quality of life. However, ESD had lower rate of en bloc resection [OR = 0.07, 95%CI: (0.03, 0.21), P < 0.00001], histologically complete resection [OR = 0.07, 95%CI: (0.03, 0.14), P < 0.00001], curative resection [OR = 0.06, 95%CI: (0.01, 0.27), P = 0.002], and higher rate of local recurrence [OR = 5.42, 95%CI: (2.91, 10.11), P < 0.00001], metachronous cancer [OR = 10.84, 95%CI: (6.43, 18.26), P < 0.00001], synchronous cancer [OR = 6.59, 95%CI: (1.96, 22.1), P = 0.002]. ESD also led to lower disease-free survival [HR = 4.58, 95%CI: (2.79, 7.52), P < 0.00001] and recurrence-free survival [HR = 1.99, 95%CI: (1.38, 2.87), P = 0.0002]. No significant differences in overall survival (OS) and disease-specific survival (DSS) between ESD and surgery were observed. CONCLUSIONS ESD offers a method of less expensive, less trauma, faster recovery and better quality of life compared to surgery for EGC. However, ESD is associated with higher risk of recurrence without compromising OS and DSS. Strict and careful surveillance after ESD is needed. Recurrent EGCs following ESD can usually be detected in early stage and successfully managed by repeated ESD. Accordingly, ESD technique provides an alternative to surgical resection for highly selected EGC patients.

Low Frequency of Lymph Node Metastases in Patients in the United States With Early-stage Gastric Cancers That Fulfill Japanese Endoscopic Resection Criteria. Clin Gastroenterol Hepatol 2019; 17:1763-1769. [PMID: 30471457 DOI: 10.1016/j.cgh.2018.11.031] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2018] [Revised: 11/01/2018] [Accepted: 11/02/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND & AIMS In the West, early gastric cancer is increasingly managed with endoscopic resection (ER). This is, however, based on the assumption that the low prevalence and risk of lymph node metastases observed in Asian patients is applicable to patients in the United States. We sought to evaluate the frequency of and factors associated with metastasis of early gastric cancers to lymph nodes, and whether the Japanese ER criteria are applicable to patients in the US. METHODS We performed a retrospective study of 176 patients (mean age 68.5 years; 59.1% male; 58.5% white) who underwent surgical resection with lymph node dissection of T1 and Tis gastric adenocarcinomas, staged by pathologists, at 7 tertiary care centers in the US from January 1, 1999, through December 31, 2016. The frequency of lymph node metastases and associated risk factors were determined. RESULTS The mean size of gastric adenocarcinomas was 23.0 ± 16.6 mm-most were located in the lower-third of the stomach (67.0%), invading the submucosa (55.1%), and moderately differentiated (31.3%). Lymphovascular invasion was observed in 18.2% of lesions. Overall, 20.5% of patients had lymph node metastases. Submucosal invasion (odds ratio, 3.9; 95% CI, 1.4-10.7) and lymphovascular invasion (odds ratio, 4.6; 95% CI, 1.8-12.0) were independently associated with increased risk of metastasis to lymph nodes. The frequency of lymph node metastases among patients fulfilling standard and expanded Japanese criteria for ER were 0 and 7.5%, respectively. CONCLUSIONS The frequency of lymph node metastases among patients with early gastric cancer in a US population is higher than that of published Asian series. However, early gastric cancer lesions that meet the Japanese standard criteria for ER are associated with negligible risk of metastasis to lymph nodes, so ER can be recommended for definitive therapy. Expanded criteria cancers appear to have a higher risk of metastasis to lymph nodes, so ER may be considered for select cases.

Abstract
With the wide application of endoscopic resection for early gastric cancer (EGC) by not only Asian endoscopists but also those from Western countries, reviews on standardized treatment processes before and after endoscopic resection are nevertheless lacking. In this article we provide a narrative review of studies on the selection of appropriate EGC for endoscopic resection and the follow-up strategies for those with histologically confirmed EGC after endoscopic resection. EGC should be comprehensively assessed before endoscopic resection, including its exact margin, invasive depth and risk of lymph node metastasis (LNM). While the curative resection status of EGC may be evaluated after endoscopic resection based on the newly developed eCura system, although this needs to be further verified. Surveillance with endoscopy and computed tomography scan is necessary for patients with an EGC level A or B. An additional endoscopic resection is recommended for patients with a level-C1 EGC. For patients with a level-C2 EGC, close follow-up is suggested for low-risk tumors of level C2 and additional surgery for those at high risks. Further postoperative strategy is suggested based on comprehensive assessment of the risk of LNM, patient's quality of life and wishes.

Abstract
Importance Lymph node status is the primary determinant in treatment decision making in early gastric cancer (EGC). Current evaluation methods are not adequate for estimating lymph node metastasis (LNM) in EGC. Objective To develop and validate a prediction model based on a fully quantitative collagen signature in the tumor microenvironment to estimate the individual risk of LNM in EGC. Design, Setting, and Participants This retrospective study was conducted from August 1, 2016, to May 10, 2018, at 2 medical centers in China (Nanfang Hospital and Fujian Provincial Hospital). Participants included a primary cohort (n = 232) of consecutive patients with histologically confirmed gastric cancer who underwent radical gastrectomy and received a T1 gastric cancer diagnosis from January 1, 2008, to December 31, 2012. Patients with neoadjuvant radiotherapy, chemotherapy, or chemoradiotherapy were excluded. An additional consecutive cohort (n = 143) who received the same diagnosis from January 1, 2011, to December 31, 2013, was enrolled to provide validation. Baseline clinicopathologic data of each patient were collected. Collagen features were extracted in specimens using multiphoton imaging, and the collagen signature was constructed. An LNM prediction model based on the collagen signature was developed and was internally and externally validated. Main Outcomes and Measures The area under the receiver operating characteristic curve (AUROC) of the prediction model and decision curve were analyzed for estimating LNM. Results In total, 375 patients were included. The primary cohort comprised 232 consecutive patients, in whom the LNM rate was 16.4% (n = 38; 25 men [65.8%] with a mean [SD] age of 57.82 [10.17] years). The validation cohort consisted of 143 consecutive patients, in whom the LNM rate was 20.9% (n = 30; 20 men [66.7%] with a mean [SD] age of 54.10 [13.19] years). The collagen signature was statistically significantly associated with LNM (odds ratio, 5.470; 95% CI, 3.315-9.026; P < .001). Multivariate analysis revealed that the depth of tumor invasion, tumor differentiation, and the collagen signature were independent predictors of LNM. These 3 predictors were incorporated into the new prediction model, and a nomogram was established. The model showed good discrimination in the primary cohort (AUROC, 0.955; 95% CI, 0.919-0.991) and validation cohort (AUROC, 0.938; 95% CI, 0.897-0.981). An optimal cutoff value was selected in the primary cohort, which had a sensitivity of 86.8%, a specificity of 93.3%, an accuracy of 92.2%, a positive predictive value of 71.7%, and a negative predictive value of 97.3%. The validation cohort had a sensitivity of 90.0%, a specificity of 90.3%, an accuracy of 90.2%, a positive predictive value of 71.1%, and a negative predictive value of 97.1%. Among the 375 patients, a sensitivity of 87.3%, a specificity of 92.1%, an accuracy of 91.2%, a positive predictive value of 72.1%, and a negative predictive value of 96.9% were found. Conclusions and Relevance This study's findings suggest that the collagen signature in the tumor microenvironment is an independent indicator of LNM in EGC, and the prediction model based on this collagen signature may be useful in treatment decision making for patients with EGC.

Abstract
BACKGROUND AND AIMS To optimize therapeutic decision-making in early invasive colorectal cancer (T1 CRC) patients, it is important to elicit the patient's perspective next to considering medical outcome. Because empirical data on patient-reported impact of different treatment options are lacking, we evaluated patients' quality of life, perceived time to recovery, and fear of cancer recurrence after endoscopic or surgical treatment for T1 CRC. METHODS In this cross-sectional study, we selected patients with histologically confirmed T1 CRC who participated in the Dutch Bowel Cancer Screening Programme and received endoscopic or surgical treatment between January 2014 and July 2017. Quality of life was measured using the European Organization for Research and Treatment 30-item Core Quality of Life Questionnaire and the 5-level EuroQoL 5-dimension questionnaire. We used the Cancer Worry Scale (CWS) to evaluate patients' fear of cancer recurrence. A question on perceived time to recovery after treatment was also included in the set of questionnaires sent to patients. RESULTS Of all 119 eligible patients, 92.4% responded to the questionnaire (endoscopy group, 55/62; surgery group, 55/57). Compared with the surgery group, perceived time to recovery was on average 3 months shorter in endoscopically treated patients after adjustment for confounders (19.9 days vs 111.3 days; P = .001). The 2 treatment groups were comparable with regard to global quality of life, functioning domains, and symptom severity scores. Moreover, patients in the endoscopy group did not report more fear of cancer recurrence than those in the surgery group (CWS score, 0-40; endoscopy 7.6 vs surgery 9.7; P = .140). CONCLUSIONS From the patient's perspective, endoscopic treatment provides a quicker recovery than surgery, without provoking more fear of cancer recurrence or any deterioration in quality of life. These results contribute to the shared therapeutic decision-making process of clinicians and T1 CRC patients.

Abstract
BACKGROUND The current standard treatment modality for clinical submucosal invasive (cT1b) early gastric cancer (EGC) is surgery. However, there are discrepancies in T staging between pre- and post-operative findings, and in cases of overestimation, patients may lose the opportunity to preserve the stomach. The aim of this study was to analyze surgical outcomes of cT1b EGC and determine the pre-treatment factors favoring ESD. METHODS Patients who underwent gastrectomy for cT1b EGC with a tumor size of 30 mm or less in diameter and differentiated-type histology were retrospectively reviewed from January 2010 to December 2014. According to the final surgical pathologic results, two groups were classified: patients whose pathologic results qualified for current ESD indication (ESD-qualified group, n = 203) and patients whose pathologic results made them ineligible for ESD (ESD-disqualified group, n = 261). The preoperative clinical characteristics were compared. RESULTS Forty-three percent of the patients (203/464) who underwent gastrectomy for cT1b EGC qualified for ESD; their endoscopic lesion tended to be smaller than 20 mm in size and located in the distal part of stomach. In addition, the ESD-qualified group showed a significantly higher proportion of well-differentiated tubular adenocarcinoma on endoscopic biopsy and of the flat/depressed type in the endoscopic evaluation. CONCLUSION Forty-three percent of the patients with cT1b EGC who underwent gastrectomy had a chance to preserve their stomach by ESD. Therefore, pre-treatment factors such as endoscopic lesion size, location, histology, and gross type should be considered for treatment modality selection for cT1b EGC.

Asian Nurs Res (Korean Soc Nurs Sci) 2019; 13:38-46. [PMID: 30633996 DOI: 10.1016/j.anr.2019.01.001] [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: 06/26/2018] [Revised: 12/27/2018] [Accepted: 01/02/2019] [Indexed: 02/06/2023] Open
Abstract
PURPOSE This study aimed to develop a model for estimating the quality of life mediated by adaptation to changes experienced after stomach cancer diagnosis and surgery in patients with gastrectomy and to verify the model based on the Cancer Survivor Adaptation Model by Naus et al. (2009) and literature reviews. METHODS Data was collected from 297 gastric cancer patients who underwent a gastrectomy at an outpatient clinic of two university hospitals in Daegu city from May to August, 2016. The exogenous variables were perceived gastrointestinal symptoms, self-efficacy, anxiety, social support, and spiritual well-being. The endogenous variables were adaptation and quality of life, and adaptation was the mediating variable. For data analysis, structural equation modeling was performed using IBM SPSS 21.0 and AMOS 18.0. RESULTS The fitness parameters of the final model showed a reasonable fit to the data. Based on R2, the exogenous variables explained 73.9% of the quality of life of stomach cancer patients who underwent surgery, through the mediation of adaptation; adaptation alone explained 73.5% of quality of life. Adaptation of stomach cancer patients with gastrectomy was a factor that strongly influenced their quality of life. CONCLUSION It is important for gastric cancer patients with gastrectomy to adapt well to changes after surgery in order to improve the quality of life. Nursing interventions to aid successful adaptation would ultimately exert positive influences and improve the patients' quality of life.

Surg Endosc 2019; 33:26-32. [PMID: 30298447 DOI: 10.1007/s00464-018-6451-2] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2018] [Accepted: 09/05/2018] [Indexed: 01/21/2023]
Abstract
BACKGROUND For successful endoscopic treatment of early gastric cancer (EGC), absolute criteria for a curative en bloc resection were initially established to include predominantly differentiated mucosal lesions ≤ 2 cm in diameter without ulceration. These indications were subsequently expanded to include larger, ulcerated, and predominantly undifferentiated mucosal lesions. In addition, differentiated type adenocarcinomas ≤ 3 cm with slight submucosal invasion of < 500 µm (pT1b1) are regarded as "curative" under the expanded criteria. However, data derived from studies of surgical specimens in patients with pT1b1 EGC have yielded varying rates of lymph node metastasis (LNM). METHOD A systemic review was conducted using the pooled analysis to calculate the incidence of LNM in pT1b1 EGC, and to investigate whether using a cut-off value of < 300 µm would decrease the risk of LNM in patients with submucosal EGC. RESULTS Nineteen articles were included. 1507 patients with pT1b1 EGC met the expanded indications. The incidence of LNM was 3% (45 out of 1507 patients). In a subgroup analysis of three studies, there was no significant difference in the LNM between pT1b EGC < 300 µm and < 500 µm [3/121(2.5%) vs. 5/180 (2.8%)] (OR 0.89, 95% CI 0.22-3.54). CONCLUSION Overall, expanding the indications for endoscopic resection of EGC to include lesions ≤ 3 cm T1b1 is associated with a potential risk of LNM of 3%. In countries outside of Japan, we found a slightly higher risk of LNM (4.0%). These estimates of LNM should be incorporated into decisions regarding further management of patients with EGC ≤ 3 cm who are found to have slight submucosal invasion (< 500 µm) in an ESD specimen. Standardization of specimen handling and histological evaluation is essential if the Japanese results of endoscopic treatment for EGC are to be successfully applied in other parts of the world.

Abstract
BACKGROUND The risk factors of lymph node (LN) metastasis are important factors to consider in endoscopic submucosal dissection in early gastric cancer (EGC). The aim of the study was to identify the correlation between mixed histology and LN metastasis in EGC. METHODS A total of 1645 patients who underwent curative radical gastrectomy for EGC were divided into three groups (pure differentiated [pure D], mixed, and pure undifferentiated [pure UD]) according to histologic type. They were subsequently analyzed retrospectively for LN metastasis. The patients who had mixed histology between differentiated and undifferentiated tubular adenocarcinoma were defined as mixed group. RESULTS The pure UD group was significantly younger than the other groups. Tumor size was larger in the mixed group. LN metastasis occurred more frequently in the mixed group and the pure UD group than in the pure D group (pure D, mixed, and pure UD, 7.7%, 23.2%, and 10.8%, respectively; P < 0.001). A logistic regression analysis revealed that the independent risk factors for LN metastasis were large tumor size (odd ratio [OR], 1.308), submucosal invasion (OR, 3.565), lymphovascular invasion (OR, 9.755), and histologic types of mixed (OR, 2.360) and pure UD (OR, 1.657). CONCLUSIONS Mixed histology is an important risk factor for LN metastasis in EGC. Thus, radical gastrectomy should be considered in the cases of mixed-type histology after endoscopic resection.

Abstract
BACKGROUND To compare the quality of life outcome between nurse-led and non-nurse-led interventions for patients with cancer using a meta-analysis. METHODS A systematic literature review was performed by searching randomized controlled trials about nurse-led interventions in PubMed, EMBASE, and Cochrane Library databases until June 2017. Pooled summary estimates for quality of life outcome was calculated as standardized mean difference (SMD) either on a fixed- or random-effect model via Stata 13.0 software. RESULTS Seven literatures involving 1110 patients (554 in the nurse-led group and 556 in the control group) were included. Pooled analysis showed there were no differences in the global quality of life, cognitive, emotional, role, social and physical functions, appetite loss, diarrhea, and dyspnea scales of Quality of Life Questionnaire C30 version 3.0 core (QLQ-C30) questionnaires between the nurse-led and control groups. However, the nurse-led management program significantly decreased the occurrence of constipation (SMD = -0.36, 95% CI = -0.71 to -0.00; P = .001) and insomnia (SMD = -0.33, 95% CI = -0.99 to 0.32; P = .011) and reduced the financial difficulty (SMD = -0.34, 95% CI = -0.65 to -0.03; P = .033) for patients with cancer. CONCLUSION The nurse-led disease management strategy seemed to be effective to improve constipation, insomnia, and financial impacts for patients with cancer in quality of life assessment.

Is the eCura system useful for selecting patients who require radical surgery after noncurative endoscopic submucosal dissection for early gastric cancer? A comparative study. Gastric Cancer 2018; 21:481-489.

Abstract
BACKGROUND We have established a risk-scoring system, termed the "eCura system," for the risk stratification of lymph node metastasis in patients who have received noncurative endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). We aimed to clarify whether this system contributes to the selection of patients requiring radical surgery after ESD. METHODS Between 2000 and 2011, 1,969 patients with noncurative ESD for EGC were included in this multicenter study. Depending on the treatment strategy after ESD, we had patients with no additional treatment (n = 905) and those with radical surgery after ESD (n = 1,064). After the application of the eCura system to these patients, cancer recurrence and cancer-specific mortality in each risk category of the system were compared between the two patient groups. RESULTS Multivariate Cox analysis revealed that in the high-risk category, cancer recurrence was significantly higher (hazard ratio = 3.13, p = 0.024) and cancer-specific mortality tended to be higher (hazard ratio = 2.66, p = 0.063) in patients with no additional treatment than in those with radical surgery after ESD, whereas no significant differences were observed in the intermediate-risk and low-risk categories. In addition, cancer-specific survival in the low-risk category was high in both patient groups (99.6 and 99.7%). A limitation of this study is that it included a small number of cases with undifferentiated-type EGC (292 cases). CONCLUSIONS The eCura system is a useful aid for selecting the appropriate treatment strategy after noncurative ESD for EGC. However, caution is needed when applying this system to patients with undifferentiated-type EGC.

Abstract
AIMS There are two treatment modalities for early gastric cancer (EGC)-surgery and endoscopic submucosal dissection (ESD). We aimed to compare the safety and efficacy of ESD with surgery. METHOD The article was performed by searching PubMed databases. Data were extracted using predefined form and odds ratios (OR) with 95% confidence intervals (CI) calculated and P value. RESULTS 13 studies were identified. The incidence of perforation in two groups was different [OR = 6.18 (95% CI: 1.37-27.98), P = 0.02]. The prevalences of synchronous and metachronous cancer in the ESD group were higher than those in the surgery group [OR = 8.52 (95% CI: 1.99-36.56), P = 0.004 and OR = 7.15 (95% CI: 2.95-17.32), P < 0.0001]. The recurrence and complete resection rates were different [OR = 6.93 (95% CI: 2.83-16.96), P < 0.0001 and OR = 0.32 (95% CI: 0.20-0.52), P < 0.00001]. Compared with the surgery group, the hospital stay was shorter [IV = -7.15 (95% CI: -9.08-5.22), P < 0.00001], the adverse event rate was lower, and the quality of life (QOL) was better in the ESD group. The difference of bleeding was not found. CONCLUSION ESD appears to be preferable for EGC, due to a lower rate of adverse events, shorter hospital stay, cheaper cost, and higher QOL.

Gastrointest Endosc 2018; 87:338-347.

Abstract
BACKGROUND AND AIMS Japanese criteria for curative endoscopic resection of early gastric cancer initially included nonulcerated, well-differentiated mucosal lesions ≤2 cm in diameter, known as the absolute criteria. Subsequently, these indications were expanded to include larger, ulcerated, and undifferentiated mucosal lesions as well as differentiated lesions with slight submucosal invasion. Whether patients meeting the expanded criteria can be managed safely without gastrectomy and lymph node dissection has been controversial. The risk of lymph node metastasis (LNM) in patients who met the expanded criteria is a critical factor in determining the best course of management for these patients. METHODS We comprehensively searched main reference databases for studies that included patients who underwent gastrectomy and lymph node dissection for early gastric cancer. A meta-analysis was conducted by using the random effects model. Relative risk reduction was used to compare the incidence of LNM in patients meeting the absolute criteria as compared with those meeting the expanded criteria. RESULTS Twelve studies met the inclusion criteria, providing a total of 9798 patients. The incidence of LNM was 0.2% for patients who met the absolute criteria as compared with 0.7% for patients who met the expanded criteria. Analysis of the various components of the expanded criteria was conducted, revealing that the incidence of LNM for differentiated mucosal lesions ≤3 cm with ulceration and for differentiated mucosal lesions without ulceration, irrespective of size, was 16 of 2814 (0.57%), reference range (RR) 3.01; P = .02 and 8 of 3004 (0.27%), RR 1.69; P = .37, respectively, only marginally higher than the risk of LNM associated with the absolute criteria. In contrast, undifferentiated mucosal lesions ≤2 cm and differentiated lesions <3 cm with slight submucosal invasion had a significantly higher incidence of LNM in comparison with the absolute criteria (25/972 [2.6%], RR 6.79; P = .0004 and 8/315 [2.5%], RR 6.30; P = .004, respectively). CONCLUSION Overall, expanding the indication for endoscopic resection to include mucosal nonulcerated differentiated lesions irrespective of size and differentiated mucosal ulcerated lesions <3 cm is justified with minimal increased risk in comparison to the absolute criteria. However, expanding the indication for undifferentiated lesions ≤2 cm and differentiated lesions with slight submucosal invasion (T1b) should be balanced with the risks of surgery, given the increased risk of LNM in these patients.

Abstract
BACKGROUND Data concerning the long-term outcomes of endoscopic submucosal dissection (ESD) versus surgery for early gastric cancer (EGC) are limited. We aimed to compare the long-term outcomes of ESD and surgery for patients with EGC. METHODS Data were reviewed from patients treated by ESD or surgery for EGC in 2005-2010. The primary outcome was overall survival (OS). Secondary outcomes were disease-specific survival (DSS), disease-free survival (DFS), recurrence-free survival (RFS), treatment-related complications, and hospital stay duration. RESULTS Among 617 patients, 342 underwent ESD and 275 underwent surgery. The 5-year OS rates were similar between the ESD group and the surgery group (96.9% vs 98.1%, P = 0.581). In a propensity-score-matched analysis of 117 pairs, there were no significant differences in the OS rates (96.5% vs 99.1%, P = 0.125) and DSS rates (100% vs 99.1%, P = 0.317) between the ESD group and the surgery group. The ESD group had a significantly lower DFS rate (90.3% vs 98.0%, P = 0.002), a significantly lower RFS rate (95.1% vs 98.0%, P = 0.033), a significantly higher early complication rate (6.7% vs 1.5%, P < 0.001), a significantly lower late complication rate (0% vs 9.1%, P < 0.001), and a significantly shorter median hospital stay (3 days vs 10 days, P < 0.001) than the surgery group. CONCLUSIONS ESD and surgery have comparable OS rates in patients with EGC. ESD has benefits, including a lower late complication rate and shorter hospital stay. However, RFS and DFS rates might be lower after ESD than after surgery.

Abstract
BACKGROUND The treatment of intramucosal early gastric cancer with undifferentiated-type histologies (UD-EGCs) using endoscopic submucosal dissection (ESD) is controversial. This study aimed to compare the clinical and oncologic long-term outcomes of ESD and surgery for UD-EGCs. METHODS A prospectively collected database of patients who underwent ESD or surgery between January 2006 and December 2012 was established. Patients who diagnosed with UD-EGC and satisfied the expanded indications of ESD were included. Clinical data from 111 patients treated with ESD and 382 patients underwent surgery were analyzed, and 1-1 propensity score-matched 81 pairs of patients were also compared. RESULTS In both groups, two-thirds of the UD-EGCs had signet ring cell (SRC)-type histology and about 90% of UD-EGCs were flat or depressed types. The mean size of tumors was smaller in ESD group (9.7 vs. 13.2 mm; P < 0.001). After propensity score-matched, case-matching covariates were not significantly different between the groups. Disease-free survival (DFS) was significantly shorter in the ESD group, but overall survival (OS) was not different between the two groups both in overall comparison (DFS; P < 0.001 and OS; P = 0.078) and propensity score-matched analysis (DFS; P < 0.001 and OS; P = 0.850). According to histologic type, OS of SRC histology was not different between the group, both in overall comparison and propensity score-matched analysis (P = 0.286 and P = 0.210). On the other hands, OS of poorly differentiated adenocarcinoma was significantly shorter in ESD group in overall comparison (P = 0.007), but was not as so in propensity score-matched analysis (P = 0.088). CONCLUSIONS ESD might be a complementary option for the treatment of UD-EGCs, especially in those with SRC-type histology based on strict expanded indications. Nonetheless, close endoscopic surveillance is required because of a high incidence of intragastric recurrence.

Endoscopic resection versus radical gastrectomy for early gastric cancer in Asia: A meta-analysis. Int J Surg 2017; 48:45-52. [PMID: 28987558 DOI: 10.1016/j.ijsu.2017.09.068] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2017] [Revised: 09/18/2017] [Accepted: 09/24/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND To compare the efficacy and safety of endoscopic resection (ER) and radical gastrectomy (RG) for early gastric cancer (EGC) in Asia. MATERIALS AND METHODS We systematically searched relevant articles published before September 1, 2017. We evaluated the quality of the included non-randomized studies using the Newcastle-Ottawa Scale (NOS). Meta-analysis was carried out using RevMan 5.3 software. The odds ratio (OR) with 95% confidence intervals (CI) were used for the dichotomous data. RESULTS Fifteen retrospective studies were included in this analysis (3737 patients in the ER group and 4246 patients in RG group). No significant differences in the three-year survival rate (OR, 0.87; 95%CI, 0.50-1.53) and five-year survival rate (OR, 0.81; 95%CI, 0.58-1.13) between the ER and RG groups were observed. Although patients undergoing ER had a higher risk of recurrence (OR, 6.07; 95%CI 4.17-8.84) and the occurrence of metachronous cancer (OR, 8.35; 95%CI, 5.48-12.75), recurrent or metachronous gastric cancers following ER were successfully detected and removed using the endoscopic technique. Higher recurrence in the ER group may be associated with its lower en bloc resection rate (OR, 0.05; 95%CI, 0.02-0.14) and complete resection rate (OR, 0.03; 95%CI, 0.01-0.08). Importantly, although the three-year survival and five-year survival were similar in the two groups, the complication rate in the ER group was significantly lower than that in the RG group. CONCLUSION ER is a good choice for patients with small EGC lesions (≤2 cm) without lymph node metastasis, especially in elderly patients with various medical comorbidities and in patients who cannot tolerate abdominal surgery or who meet the criteria but decline surgery. In contrast, RG is recommended when the diameter of the tumor is large (>2 cm) and preoperative examination suggests the possible presence of lymph node metastasis.

Abstract
This review article summarizes knowledge about metachronous gastric cancer (MGC) occurring after curative endoscopic resection (ER) of early gastric cancer (EGC), treatment outcomes of patients who developed MGC, and efficacy of Helicobacter pylori eradication to prevent MGC. The incidence of MGC following curative ER increases over time and is higher than in patients undergoing gastrectomy. Increasing age and multifocal EGC are independent risk factors for developing MGC. An MGC following curative ER is usually a small (<20 mm) and differentiated intramucosal cancer. Most MGC lesions are found at an early stage on semiannual or annual surveillance endoscopy and are successfully treated by further ER, with excellent long-term outcomes. Eradication of H. pylori may reduce the risk of MGC following ER of EGC, but further prospective studies with long-term outcomes are required. Surveillance endoscopy following gastric ER should be continued indefinitely, due to the risk of MGC even after successful H. pylori eradication. Risk stratification and tailored endoscopic surveillance schedules need to be developed.

Abstract
BACKGROUND AND PURPOSE Previous studies comparing survival outcomes between patients who did and did not undergo additional surgery after non-curative endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) were limited in that the baseline characteristics differed significantly between the groups. We aimed to address this limitation and compared survival outcomes between these two groups using propensity score matching analysis. METHODS The study enrolled 1969 consecutive patients who underwent non-curative ESD for EGC between 2000 and 2011 at any of 19 institutions across Japan. Using propensity score matching analysis, patients who underwent additional surgery (n = 1064) were compared with patients who did not (n = 905). Overall survival (OS) and disease-specific survival (DSS) after ESD were compared between both groups. RESULTS Propensity score matching analysis yielded 553 matched pairs and well-balanced baseline characteristics between the two groups. The 5-year OS rates were 91.0% in the additional surgery group and 75.5% in the no additional surgery group, and the 5-year DSS rates were 99.0 and 96.8%, respectively. OS and DSS in the additional surgery group were significantly higher than in the no additional surgery group (OS, p < 0.001; DSS, p = 0.013). In Cox proportional hazard analysis, additional surgery significantly reduced gastric cancer-related death after non-curative ESD for EGC (hazard ratio 0.33, 95% confidence interval 0.12-0.79, p = 0.012). CONCLUSIONS Our findings suggest that additional surgery reduces mortality after non-curative ESD for EGC. We recommend additional surgery for patients after non-curative ESD for EGC.

Abstract
BACKGROUND/AIMS Endoscopic submucosal dissection (ESD) is an effective treatment for early gastric cancer (EGC) that has demonstrated a minimal risk of lymph node metastasis in retrospective studies. We sought to prospectively evaluate the short-term outcomes of ESD treatment in EGCs. METHODS A prospective multicenter cohort study of neoplasms 3 cm or less in diameter at endoscopic size evaluation was performed in 12 Korean ESD study grouprelated university hospitals and the National Cancer Center. Resected specimens were evaluated by the central pathologic review board. RESULTS A patient cohort (n=712) with a total of 737 EGCs was analyzed. The margin-free en bloc resection rate was 97.3%, and curative resection of 640 lesions (86.8%) was achieved. Lower curative resection rates were associated with lesions 2 to 3 cm in size prior to ESD compared with lesions 2 cm or less in size (78.6% vs 88.1%, respectively, p=0.009). Significant factors associated with noncurative resection were moderately or poorly differentiated histological type, posterior wall tumor location, tumor size larger than 3 cm, ulceration, and submucosal invasion. Delayed bleeding occurred in 49 patients (6.9%), and 12 patients (1.7%) exhibited perforations. CONCLUSIONS ESD is an effective treatment with a high curative resection rate for EGCs that meets relatively conservative pre-ESD indications. Long-term survival outcomes should be evaluated in followup studies.

Abstract
Introduction This pilot exploratory study aimed to compare the health-related quality of life (HRQOL) among patients diagnosed with different types of cancer receiving peripherally inserted central catheters (PICCs). Methods A multicenter cross-section study of cancer patients with PICCs was performed from February 1, 2013 to April 24, 2014. The primary objective of this study was to compare HRQOL in different cancer type patients with PICC. HRQOL was examined based on European Organisation for Research and Treatment of Cancer Quality-of-Life Questionnaire-Core 30 (EORTC QLQ-C30). Multiple linear regression models were conducted for coping with potential confounding variables. We also examined PICC-related quality of daily life with a self-made questionnaire. Results Three hundred and fifty-seven cancer patients with PICC completed the survey in nine teaching hospitals. Lung cancer patients with PICC reported the worst dyspnea. Digestive tract cancer patients reported the worst appetite loss. Patients with hematologic malignancy reported the worst emotional, social function, fatigue and financial impact. Breast cancer patients reported better HRQOL. Baseline variables were proven not significant predictors of EORTC QLQ-C30 global health status. In self-made survey, pain after PICC insertion was null or a little in 98.6% of cancer patients. Limitation of upper extremity activity was null or a little in 94.1% of patients. Conclusions HRQOL varies in different types of cancer patients with PICC. PICC may have a low impact on cancer patients’ HRQOL. Further large sample studies are needed.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) is accepted as a standard treatment in patients with early gastric cancer (EGC) who have a negligible risk of lymph node metastasis. The aim of this study was to compare the short-term and long-term outcomes between ESD and surgery in patients with EGC that fulfilled the expanded indication of ESD on their final pathologic report. METHODS We reviewed the clinical data of patients who underwent gastric ESD and surgery between January 2007 and December 2012. Patients with pathologically confirmed EGC that fulfilled the expanded indication of ESD on their final pathologic report were analyzed. RESULTS Among 2023 patients, 817 (40.4%) underwent ESD and 1206 (59.6%) underwent surgery. The proportion of cases meeting the absolute indication was significantly higher in the ESD group than in the surgery group (66.0 vs. 26.2%). Lesions on the middle third, >3 cm in size, flat or depressed, and of undifferentiated histology were significantly more common in the surgery group than in the ESD group. The ESD group showed lower acute complication rates [8.1% (66 of 817) vs. 18.1% (218 of 1206), P ≤ 0.001] and procedure-related mortality [0 vs. 0.3% (4 of 1206), P = 0.153] than the surgical group. The annual incidence of recurrent gastric cancer was 2.18% in the ESD group and 0.19% in the surgery group. The 5-year overall and disease-specific survival rates were not significantly different between the ESD group and the surgery group (overall survival: 96.4 vs. 97.2%, P = 0.423; disease-specific survival: 99.6 vs. 99.2%, P = 0.203). CONCLUSIONS Although EGC lesions had poorer features in the surgery group than in the ESD group, ESD was comparable to surgery for EGCs that fulfilled the expanded indication of ESD, with lower rates of acute complication and comparable overall survival.

Abstract
BACKGROUND Sufficient information is not available on the extent to which lymph node metastasis (LNM) and prognosis are affected by submucosal manipulation during endoscopic submucosal dissection (ESD) for submucosal invasive gastric cancer (SMGC). We aimed to identify the effects of submucosal manipulation during ESD on LNM and prognosis in patients with SMGC. METHODS From 19 institutions in Japan, 2526 patients who failed to meet the current curative criteria for ESD between 2000 and 2011 were recruited. After exclusion, 1969 patients were remained. Based on the treatment strategy after ESD, 1064 patients underwent additional radical surgery. A total of 890 of 1064 patients with SMGC, LNM and cancer recurrence, and prognosis were retrospectively reviewed. RESULTS The median follow-up duration was 67 months. A total of 214 patients had SM1 (depth of tumor invasion from the muscularis mucosae <500 μm) invasive cancer and 676 patients had SM2 (depth of tumor invasion from the muscularis mucosae ≥500 μm) invasive cancer. LNM was found in 84 patients (9.4%), and 14 patients (1.6%) developed cancer recurrence. The 3-year and 5-year overall survival rates were 96.1 and 91.7%, respectively. The 3-year and 5-year disease-specific survival rates were 99.3 and 98.5%, respectively. CONCLUSIONS The rates of LNM and cancer recurrence, and prognosis of patients who underwent additional radical surgery after non-curative ESD for SMGC were excellent. Submucosal manipulation during ESD for SMGC does not seem to enhance the risk for LNM or worsen the prognosis compared to surgical series.

Clin Endosc 2017; 50:473-478. [PMID: 28434216 PMCID: PMC5642073 DOI: 10.5946/ce.2016.143] [Citation(s) in RCA: 9] [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: 10/24/2016] [Revised: 02/27/2017] [Accepted: 03/02/2017] [Indexed: 12/20/2022] Open
Abstract
Background/Aims Early gastric cancer (EGC) with ulcerations can be treated via endoscopic resection (ER) when it is differentiated pathologically, limited to the mucosa, and <3 cm in diameter. The presence of ulceration is a key factor in deciding treatment strategies and is usually diagnosed during endoscopic examination. The aim of this study was to evaluate whether ulcerations in EGC can be clearly defined among endoscopists and which factors are related to the differences. Methods A survey questionnaire, composed of demographic features and endoscopic images of seven patients with EGC, was presented to the endoscopists via e-mail. The endoscopists were asked whether such patients have ulcerations in the lesions. Results The questionnaires were e-mailed to 197 endoscopists, and 103 doctors replied. The presence of an endoscopic ulceration was defined differently among the endoscopists, depending on the duration of endoscopic practice and the experience of endoscopic submucosal dissection. The differences were especially high in the lesions without mucosal breaks and converging folds, which were expected to be viewed as non-ulcerative. Conclusions Before ER, endoscopic ulcerations in EGC must be reviewed by experienced endoscopists to reduce overestimations, and adequate educational programs for trainees should be established.

Abstract
Here we report a case of postoperative metachronous distant metastasis after endoscopic mucosal resection (EMR) for early gastric cancer. The process of diagnosis and treatment is described in detail, with data including laboratory tests, imaging examinations, endoscopic findings, pathological examinations, and treatment plan reported. The patient received 12 cycles of chemotherapy with the FOLFOX4 regimen [oxaliplatin 85 mg/m2 as a 2-h infusion on day 1 and a 2-h infusion of LV 200 mg/(m2·d) followed by a 5-fluorouridine bolus 400 mg/(m2·d) and 22-h infusion 600 mg/(m2·d) for 2 consecutive days every 2 wk] and apatinib, and a partial response was achieved. This case suggests that, as a treatment for early gastric cancer, EMR may not completely resect the lesions and cannot handle metastatic lymph nodes. Its clinical effects remain controversial.

Abstract
OBJECTIVE Our goal was to estimate the feasibility and efficacy of endoscopic submucosal excavation (ESE) for the treatment of gastrointestinal stromal tumors (GISTs) in the cardia. MATERIALS AND METHODS We analyzed the clinical data of 30 patients who were diagnosed with GISTs after ESE in the cardia at the Endoscopy Center of Renmin Hospital of Wuhan University (China) from June 2009 to 2015. We evaluated the operative and postoperative conditions and long-term follow-up of these patients. RESULTS The success rate and the complete resection rate were both 100%. The maximum diameter of the tumor ranged from 1.0 to 3.5 cm (2.2±0.2 cm). The operation time was 20 to 120 min (50±5 min). During ESE, bleeding occurred in all cases (100%) with a mean blood loss of 50 mL, and perforation in 6 (20%), including 2 full-thickness resections. GIST was confirmed by pathology in all cases. Follow-up included endoscopy at 1, 3, and 6 months, and at 1 year. At 1 month, ulcer was detected in 23 cases (76.67%), titanium clips remained in 17 cases (56.67%), and scar tissues were observed in the remainder. No recurrence was found with gastroscopy. CONCLUSIONS The cardia is a unique anatomic location for GISTs, which often requires complex surgeries prone to complications. ESE for GISTs of the cardia is a challenging, but safe and effective procedure.

Risk Factors for Additional Surgery after Iatrogenic Perforations due to Endoscopic Submucosal Dissection. Gastroenterol Res Pract 2017; 2017:6353456. [PMID: 28316622 PMCID: PMC5338066 DOI: 10.1155/2017/6353456] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2016] [Revised: 01/10/2017] [Accepted: 01/24/2017] [Indexed: 01/11/2023] Open
Abstract
Objectives. Endoscopic resection (ER) is commonly performed to treat gastric epithelial neoplasms and subepithelial tumors. The aim of this study was to predict the risk factors for surgery after ER-induced perforation. Methods. We retrospectively reviewed the data on patients who received gastric endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) between January 2010 and March 2015. Patients who were confirmed to have perforation were classified into surgery and nonsurgery groups. We aimed to determine the risk factors for surgery in patients who developed iatrogenic gastric perforations. Results. A total of 1183 patients underwent ER. Perforation occurred in 69 (5.8%) patients, and 9 patients (0.8%) required surgery to manage the perforation. In univariate analysis, anterior location of the lesion, a subepithelial lesion, two or more postprocedure pain killers within 24 hrs, and increased heart rate within 24 hrs after the procedure were the factors related to surgery. In logistic regression analysis, the location of the lesion at the anterior wall and using two or more postprocedure pain killers within 24 hrs were risk factors for surgery. Conclusion. Most cases of perforations after ER can be managed conservatively. When a patient requires two or more postprocedure pain killers within 24 hrs and the lesion is located on the anterior wall, early surgery should be considered instead of conservative management.

Is radical surgery necessary in all patients who do not meet the curative criteria for endoscopic submucosal dissection in early gastric cancer? A multi-center retrospective study in Japan. J Gastroenterol 2017; 52:175-184. [PMID: 27098174 DOI: 10.1007/s00535-016-1210-4] [Citation(s) in RCA: 96] [Impact Index Per Article: 13.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2016] [Accepted: 03/31/2016] [Indexed: 02/06/2023]
Abstract
BACKGROUND Although radical surgery is routinely performed for patients who do not meet the curative criteria for endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) due to the risk of lymph node metastasis (LNM), this standard therapeutic option may be excessive given the lower number of patients with LNM. Therefore, we aimed to investigate long-term outcomes and validate risk factors predicting recurrence after ESD. METHODS Of 15,785 patients who underwent ESD for EGC at 19 institutions between 2000 and 2011, 1969 patients not meeting the curative criteria were included in this multi-center study. Based on the treatment strategy after ESD, patients were divided into radical surgery (n = 1064) and follow-up (no additional treatment, n = 905) groups. RESULTS Overall survival (OS) and disease-specific survival (DSS) were significantly higher in the radical surgery group than in the follow-up group (p < 0.001 and p = 0.012, respectively). However, the difference in 3-year DSS between the groups (99.4 vs. 98.7 %) was rather small compared with the difference in 3-year OS (96.7 vs. 84.0 %). LNM was found in 89 patients (8.4 %) in the radical surgery group. Lymphatic invasion was found to be an independent risk factor for recurrence in the follow-up group (hazard ratio 5.23; 95 % confidence interval 2.01-13.6; p = 0.001). CONCLUSIONS This multi-center study, representing the largest cohort to date, revealed a large discrepancy between OS and DSS in the two groups. Since follow-up with no additional treatment after ESD may be an acceptable option for patients at low risk, further risk stratification is needed for appropriate individualized treatment strategies.

Abstract
BACKGROUND AND AIMS Although endoscopic submucosal dissection (ESD) for expanded-indication lesions of differentiated-type early gastric cancer (EGC) has been widely accepted, no prospective randomized study has been conducted on this subject. This study aimed to evaluate the long-term outcomes of ESD and surgery for expanded-indication lesions of differentiated-type EGC. METHODS Between 1997 and 2012, 1500 consecutive patients with EGC were treated in Osaka City University Hospital. Using propensity score matching and inverse probability of treatment weighting (IPTW), we retrospectively evaluated the long-term outcomes, risk factors for mortality, and adverse events for patients with expanded-indication lesions of differentiated-type EGC who underwent ESD or surgical treatments. RESULTS A total of 308 patients with expanded-indication lesions of differentiated-type EGC confirmed by pathologic examination after ESD or surgery met the eligibility criteria. After matching, the 5-year overall survival rate was higher in the ESD group than in the surgery group (97.1% vs 85.8%; P = .01). We also found that surgery was significantly associated with mortality using both the IPTW method (hazard ratio [HR], 10.89; 95% confidence interval [CI], 1.37-86.6; P < .01), and Cox analysis (HR, 8.60; 95% CI, 1.11-66.52; P = .04) after matching. Significantly fewer adverse events were associated with ESD than with surgery (6.8% vs 28.4%; P < .01). No cause-specific mortality was observed in either group. CONCLUSIONS Our results indicate that ESD might be an alternative treatment modality for expanded-indication lesions of differentiated-type EGC.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) is an alternative to surgical resection for treating early gastric cancer (EGC). However, there have been limited reports on the long-term outcome of ESD compared to that of surgical resection. The aim of this study was to evaluate the immediate and long-term clinical and oncologic outcomes of ESD compared to surgical resection. METHOD We retrospectively reviewed data of patients in five centers who were treated with ESD or surgical resection for EGC within expanded criteria for ESD from 2006 to 2008. RESULT ESD group had significantly shorter procedure times, shorter fasting period, and shorter hospital stay than the surgical resection group. Immediate complications in the surgical resection group were more common compared to those in the ESD group. Five-year cancer recurrence rate of the ESD group was 12.3 % and significantly higher than 2.1 % of the surgical resection group (P = 0.001). Five-year disease-free survival rate of the surgical resection group was 97 %, which was significantly higher than 85 % of the ESD group (P = 0.001). Metachronous lesions were equally found every year during the follow-up period in the ESD group. Five-year overall survival rates were 100 % for both groups. CONCLUSION ESD might be an acceptable and effective treatment for EGC considering overall survival rates with fewer early complication rates and shorter duration of hospital stay compared to surgical resection. However, intensive and persistent endoscopic surveillance should be performed after ESD for early detection of metachronous lesions.

Abstract
Background and study aims: Hereditary diffuse gastric cancer (HGGC), an autosomal dominant tumor-syndrome, accounts for 1 % to 3 % of gastric cancers worldwide. Presumably 30 % to 40 % of all patients fulfilling the clinical guidelines for HDGC are carriers of a pathogenic mutation in the CDH1 gene. Patients often show multiple foci of signet ring cell carcinoma at early age and are advised to undergo prophylactic total gastrectomy (PTG). Our aim was to improve the endoscopic detection of HDGC by using an enhanced endoscopic protocol. Patient and methods: Patients with a proven CDH1 germline mutation identified in our institute were prospectively included. Patients were advised to undergo PTG and offered a baseline endoscopic examination prior surgery. Examination was performed by using high-resolution white-light endoscopy and pan-gastric chromoendoscopy with indigo carmine as dye combined with targeted and multiple random biopsies assessed by an expert histopathologist. Postoperative histopathology was compared with results from endoscopic biopsies. Results: Between September 2012 and November 2014 8 patients with a proven CDH1 germline mutation were included. We conducted 44 targeted (6.3/patient) and 225 random (32.1/patient) biopsies in 7 patients. We detected 1 gastric cancer by random biopsy (14 %). All other examinations showed no signs of cancer. Histopathology of gastrectomy specimen revealed multiple foci of gastric carcinoma in 6 patients (86 %) with a total number of 27 cancer foci. Conclusions: Examination with targeted and random biopsies combined with chromoendoscopy is not able to detect small foci of gastric cancer in CDH1 mutation carriers. Therefore PTG is advocated in these patients.

GE-PORTUGUESE JOURNAL OF GASTROENTEROLOGY 2016; 24:31-39. [PMID: 28868336 PMCID: PMC5579519 DOI: 10.1159/000450874] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/02/2016] [Revised: 07/24/2016] [Indexed: 12/16/2022]
Abstract
Introduction Endoscopic submucosal dissection (ESD) is an effective treatment for gastric superficial neoplasms and curative in 80-85% of the patients. The aims of this study were to identify risk factors for non-curative resection and metachronous development, and to evaluate patient management and outcome after non-curative resection. Methods In this single-centre study, the outcome of consecutive patients submitted to gastric ESD was assessed during a minimum follow-up of 18 months. Univariate analysis and multivariate logistic regression were performed to identify risk factors. Results ESD was performed in 194 lesions (164 patients) between 2005 and 2014. The median follow-up was 40 months. En bloc and complete resection rates were 95.3 and 93.8%, respectively. Male sex, larger tumor size, longer procedural time, and more advanced histology were associated with a non-curative resection (p < 0.05), but only carcinoma detected in biopsies before resection was identified as a significant risk factor on multivariate analysis. Metachronous lesions occurred in 18.4%, and the incidence rate was 4.7 lesions/100 person-years. Older age at diagnosis was identified as the only predictor of metachronous development in logistic regression. In the non-curative resection group, survival did not differ between patients allocated to surveillance and those submitted to gastrectomy; 75% of gastrectomy specimens showed no residual lesion. Conclusions The risk factors identified for non-curative resection help to improve patient selection and patient information. Older patients had an increased risk for the development of metachronous lesions. In patients with non-curative resections, individualized patient management and surveillance seems to be an adequate option in selected cases.

Abstract
Background The presence of ulcer in early gastric cancer (EGC) is important for the feasibility of endoscopic resection, only a few studies have examined the clinicopathological implications of endoscopic ulcer in EGC. Objectives To determine the role of endoscopic ulcer as a predictor of clinical behaviors in EGC. Methods Data of 3,270 patients with EGC who underwent surgery between January 2005 and December 2012 were reviewed. Clinicopathological characteristics were analyzed in relation to the presence and stage of ulcer in EGC. Based on endoscopic findings, the stage of ulcer was categorized as active, healing, or scar. Logistic regression analysis was performed to analyze factors associated with lymph node metastasis (LNM). Results 2,343 (71.7%) patients had endoscopic findings of ulceration in EGC. Submucosal (SM) invasion, LNM, lymphovascular invasion (LVI), perineural invasion, and undifferentiated-type histology were significantly higher in ulcerative than non-ulcerative EGC. Comparison across different stages of ulcer revealed that SM invasion, LNM, and LVI were significantly associated with the active stage, and that these features exhibited significant stage-based differences, being most common at the active stage, and least common at the scar stage. The presence of endoscopic ulcer and active status of the ulcer were identified as independent risk factors for LNM. Conclusions Ulcerative EGC detected by endoscopy exhibited more aggressive behaviors than non-ulcerative EGC. Additionally, the endoscopic stage of ulcer may predict the clinicopathological behaviors of EGC. Therefore, the appearance of ulcers should be carefully evaluated to determine an adequate treatment strategy for EGC.

Abstract
BACKGROUND AND AIMS The aim of this study was to identify the incidence of recurrent lesions after endoscopic submucosal dissection (ESD) and to determine whether scheduled endoscopic surveillance might control their development and treatment. METHODS We reviewed the clinical data of patients who underwent gastric ESD between March 2007 and April 2014. RESULTS A total of 1347 patients who underwent curative ESD for early gastric cancer that met the expanded indication for ESD were analyzed. Of these, recurrence at the previous ESD site occurred in 39 patients, whereas recurrence in the stomach at a site other than the ESD site occurred in 102 patients. Older age, intestinal metaplasia, flat or depressed lesions, and ESD criteria were associated with recurrence in the stomach in places other than the ESD site. The annual incidence was .84% for recurrence at the previous ESD site and 2.48% for recurrence in the stomach at other than the ESD site. In cases of local recurrence and metachronous lesions, there was a significant difference between the short- and long-surveillance interval group (≤12 months vs >12 months) in the proportions of recurrent adenocarcinoma (31.9% vs 60.9%, P = .021), additional gastrectomy (7.1% vs 46.2%, P = .033), and size (8.92 ± 4.17 mm vs 18.08 ± 10.47 mm, P = .010). CONCLUSIONS Scheduled endoscopy surveillance is necessary for detecting recurrent lesions. In addition, scheduled endoscopy surveillance might help to detect recurrent lesions at a stage early enough for a curative resection.

Abstract
Background The World Health Organization (WHO) histological classification for gastric cancer is widely accepted and used. However, its impact on predicting lymph node metastasis and recurrence in early gastric cancer (EGC) is not well studied. Material/Methods From 1987 to 2005, 2873 EGC patients with known WHO histological type who had undergone curative resection were enrolled in this study. In all, 637 well-differentiated adenocarcinomas (WD), 802 moderately-differentiated adenocarcinomas (MD), 689 poorly-differentiated adenocarcinomas (PD), and 745 signet-ring cell adenocarcinomas (SRC) were identified. Results The distribution of demographic and clinical features in early gastric cancer among WD, MD, PD, and SRC were significantly different. Lymph node metastasis was observed in 317 patients (11.0%), with the lymph node metastasis rate being 5.3%, 14.8%, 17.0%, and 6.3% in WD, MD, PD, and SRC, respectively. Univariate and multivariate analyses indicated that gender, tumor size, gross appearance, depth of invasion, and WHO classification were significantly associated with lymph node metastasis. Recurrence was observed in 83 patients (2.9%), with the recurrence rate being 2.2%, 4.5%, 3.0%, and 1.6% in WD, MD, PD, and SRC, respectively. Multivariate analysis confirmed that MD, elevated gross type, and lymph node metastasis were independent risk factors for recurrence in EGC. MD patients showed worse disease-free survival than non-MD patients (P=0.001). Conclusions WHO classification is useful and necessary to evaluate during the perioperative management of EGC. Treatment strategies for EGC should be made prudently according to WHO classification, especially for MD patients.

Abstract
Aim To compare the efficacy and safety of endoscopic resection (ER) and surgery for the treatment of early gastric cancer and precancerous lesions. Methods Databases, such as PubMed, EMBASE, Cochrane Library, and Science Citation Index, from 2000 to 2016, were searched for eligible articles. In this meta-analysis, the main outcome measurements were local recurrence, complications, metachronous lesions, hospital stay, and 5-year overall survival. Results Nine trials were identified and a total of 2748 patients were included. The rate of complication was higher in the surgery group compared with the ER group (OR 0.41; 95 % CI 0.30–0.55). The rates of local recurrence and metachronous lesions were lower in the surgery group (OR 0.03; 95 % CI 0.00–0.06; OR 8.76; 95 % CI 4.17–18.41). The hospital stay was shorter in the ER group (mean difference −6.96; 95 % CI −7.94 to −5.99). The 5-year overall survival rate did not significantly differ between the two groups (OR 1.23; 95 % CI 1.03–1.47). Conclusions We provided evidence that, ER was comparable to surgery in terms of the 5-year overall survival. In addition, ER had a lower rate of complications and shorter hospital stay, but a higher rate of local recurrence and metachronous lesions for the treatment of early gastric cancer and precancerous lesions.

Abstract
OBJECTIVES Few studies have compared the long-term outcomes of endoscopic resection and surgery. The aim of this study was to compare the long-term outcomes of endoscopic resection with those of surgery for early gastric cancer (EGC). METHODS We reviewed prospectively collected data of patients who had undergone endoscopic resection (1,290 patients) or surgery (1,273 patients) for EGC. To reduce the effect of selection bias, we performed a propensity score-matching analysis between the two groups. The primary outcome was overall survival (OS). The secondary outcomes were disease-specific survival, disease-free survival (DFS), recurrence-free survival (RFS), occurrence of metachronous gastric cancer, treatment-related complications, length of hospital stay, and 30-day outcomes. The study was designed as a non-inferiority study and tested in an intention-to-treat analysis. RESULTS In a propensity-matched analysis of 611 pairs, the 10-year OS proportion was 96.7% in the endoscopic resection group and 94.9% in the surgery group (P=0.120) (risk difference -1.8%, 95% confidence interval (CI) -4.04-0.44, Pnon-inferiority=0.014), which met the non-inferiority criterion. In contrast, the 10-year RFS proportion was 93.5% in the endoscopic resection group and 98.2% in the surgery group (P<0.001) (risk difference 4.7%, 95% CI 2.50-6.97, Pnon-inferiority=0.820), which did not meet the non-inferiority criterion, mainly because of metachronous recurrence in the endoscopic resection group. The rate of early complications was higher in the endoscopic resection group than in the surgery group (9.0 vs. 6.6%, P=0.024), whereas the rate of late complications was higher in the surgery group than in the endoscopic resection group (0.5 vs. 2.9%, P<0.001). In the multiple Cox regression analysis, patient's age, the comorbidity index, the performance index, sex, tumor morphology, and depth of invasion were predictors of OS in patients with EGC. CONCLUSIONS Endoscopic resection might not be inferior to surgery with respect to OS in patients with EGC lesions that meet the absolute or expanded criteria. However, DFS, RFS, and metachronous RFS might be lower after endoscopic resection than after surgery.

Abstract
AIM To analyze the relationship between lymph node metastasis and clinical pathology of early gastric cancer (EGC) in order to provide criteria for a feasible endoscopic therapy. METHODS Clinical data of the 525 EGC patients who underwent surgical operations between January 2009 and March 2014 in the West China Hospital of Sichuan University were analyzed retrospectively. Clinical pathological features were compared between different EGC patients with or without lymph node metastasis, and investigated by univariate and multivariate analyses for possible relationships with lymph node metastasis. RESULTS Of the 2913 patients who underwent gastrectomy with lymph node dissection, 529 cases were pathologically proven to be EGC and 525 cases were enrolled in this study, excluding 4 cases of gastric stump carcinoma. Among 233 patients with mucosal carcinoma, 43 (18.5%) had lymph node metastasis. Among 292 patients with submucosal carcinoma, 118 (40.4%) had lymph nodemetastasis. Univariate analysis showed that gender, tumor size, invasion depth, differentiation type and lymphatic involvement correlated with a high risk of lymph node metastasis. Multivariate analysis revealed that gender (OR = 1.649, 95%CI: 1.091-2.492, P = 0.018), tumor size (OR = 1.803, 95%CI: 1.201-2.706, P = 0.004), invasion depth (OR = 2.566, 95%CI: 1.671-3.941, P = 0.000), histological differentiation (OR = 2.621, 95%CI: 1.624-4.230, P = 0.000) and lymphatic involvement (OR = 3.505, 95%CI: 1.590-7.725, P = 0.002) were independent risk factors for lymph node metastasis. Comprehensive analysis showed that lymph node metastasis was absent in patients with tumor that was limited to the mucosa, size ≤ 2 cm, differentiated and without lymphatic involvement. CONCLUSION We propose an endoscopic therapy for EGC that is limited to the mucosa, size ≤ 2 cm, differentiated and without lymphatic involvement.

Abstract
BACKGROUND Endoscopic resection methods, including endoscopic mucosal resection and endoscopic submucosal dissection, have become standard treatment modalities for patients with early gastric cancer (EGC) and absolute indications, with en bloc resection being more frequent with the latter. Endoscopic resection, however, has been associated with higher recurrence and metachronous cancer rates than gastrectomy. This meta-analysis compared the efficacy and safety of endoscopic resection and gastrectomy for EGC. METHODS PubMed, EMBASE and Web of Science were electronically searched for relevant studies comparing endoscopic resection and gastrectomy for EGC from 1976 through March 2015. The primary endpoints were en bloc resection and histologically complete resection rates. The secondary endpoints were duration of hospital stay and rates of complications, recurrence, metachronous cancer and overall survival. RESULTS This meta-analysis enrolled 10 studies with 2070 patients: 993 patients who underwent endoscopic resection and 1077 who underwent gastrectomy. Endoscopic resection was associated with shorter hospital stay (standardized mean difference -2.02; 95 % confidence interval [CI] -2.64 to -1.39) and lower complication rate (relative risk [RR] 0.41; 95 % CI 0.22-0.76) than gastrectomy. However, endoscopic resection was associated with lower rates of en bloc resection (odds ratio [OR] 0.05; 95 % CI 0.02-0.16) and histologically complete resection (OR 0.04; 95 % CI 0.01-0.11) and higher rates of recurrence (RR 5.23; 95 % CI 2.43-11.27) and metachronous cancer (RR 5.22; 95 % CI 2.40-11.34) than gastrectomy. Overall survival rate (OR 1.18; 95 % CI 0.76-1.82) was similar. CONCLUSIONS Endoscopic resection is minimally invasive and as effective as surgery, suggesting that the former be considered standard treatment for EGC. It should be recommended as standard treatment for EGC with indications. Additional randomized controlled trials from more countries are required.

Abstract
The number of elderly people with superficial gastric neoplasms is increasing, but the clinical outcome of endoscopic submucosal dissection (ESD) for treating elderly people with superficial gastric neoplasms remains unclear. We aimed to compare the efficacy and safety of ESD for patients with early gastric cancer (EGC) and precancerous lesions in elderly (≥75 years of age) and nonelderly (<75 years of age) patients.From October 2005 to December 2014, 83 consecutive patients with EGC and precancerous lesions (86 lesions) who were treated using ESD in our hospital were retrospectively reviewed. There were 44 lesions in 42 elderly patients who were at least 75-years old. The following parameters were compared between the 2 groups: preexisting comorbidities, performance status (PS), lesion inclusion criteria, lesion characteristics, treatment outcomes, surgery time, duration of hospitalization, complications, and intraoperative hemodynamic changes.Elderly patients had significantly higher preexisting comorbidity rates (90.9% vs 59.5%, P = 0.001), expanded lesion criteria rates (43.2% vs 19.0%, P = 0.016), and lower best PS rates (38.6% vs 81.0%, P < 0.001) than nonelderly patients. Lesion characteristics were similar in the 2 groups. The elderly had higher intraoperative hypotension rates (47.7% vs 21.4%, P = 0.011) and oxygen desaturation rates (9.1% vs 0.0%, P = 0.045) than nonelderly patients. In addition, the elderly also had a longer surgery time (107.0 ± 51.4 vs 91.5 ± 66.2 minutes, P = 0.049) and duration of hospitalization (7.5 ± 3.8 vs 5.9 ± 2.0 days, P = 0.016) than nonelderly patients. There were no differences in the prevalence rates of en-bloc resection, complete resection, bleeding, perforation, pneumonia, or intraabdominal free air between the 2 groups.Although elderly patients who underwent ESD for superficial gastric neoplasms had an increasing risk of intraoperative hypotension and oxygen desaturation, all patients were treated appropriately without postoperative sequelae. ESD is a safe and feasible intervention for elderly patients who have more comorbidity, a worse PS and more expanded lesions.

Abstract
Gastric cancer imposes a global health burden. Although multimodal therapies have proven to benefit patients with advanced diseases after curative surgery, the prognosis of most advanced cancer patients still needs to be improved. Surgical extirpation is the mainstay of gastric cancer treatment. Indeed, without curative surgery, variations and combinations of chemotherapy and/or radiation cannot bring clinically meaningful success. Centered around D2 surgery, adjuvant and peri-operative multimodal therapies have improved survival in a certain group of gastric cancer patients. Moving toward a personalized cancer therapy era, molecular targeted strategies have been tested in clinical trials for gastric cancer. With some success and failures, we have learned valuable lessons regarding the biology of gastric cancer and the clinical relevance of biological therapies in addition to conventional treatments. Future treatment of gastric cancer will be shifted to molecularly tailored and genome information-based personalized therapy. Collaboration across disciplines and actively adopting emerging anti-cancer strategies, along with in-depth understanding of molecular and genetic underpinnings of tumor development and progression, are imperative to realizing personalized therapy for gastric cancer. Although many challenges remain to be overcome, we envision that the era of precision cancer medicine for gastric cancer has already arrived and anticipate that current knowledge and discoveries will be transformed into near-future clinical practice for managing gastric cancer patients.
