J Gastrointest Surg 2020; 24:2212-2218. [PMID: 31515762 PMCID: PMC7065947 DOI: 10.1007/s11605-019-04393-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2019] [Accepted: 09/01/2019] [Indexed: 01/31/2023]
Abstract
BACKGROUND The purpose of this study was to compare the long-term effectiveness of three lymphadenectomy strategies in patients with gastric cancer. We hypothesized that, compared with the traditional standard (D2) lymph node dissection strategy, the less aggressive modified standard (mD2) lymphadenectomy may offer superior effectiveness due to reduced operative morbidity and comparable long-term recurrence-free survival. METHODS A Markov decision analysis model was created to simulate 5-year outcomes across three lymphadenectomy approaches for gastric cancer: limited regional (D1), traditional standard (D2), and modified standard (mD2). The primary outcome was discounted quality-adjusted life-years (dQALY). Model variable estimates were derived from outcomes data and quality of life estimates published in Europe and America within the last 15 years. One-way and probabilistic sensitivity analyses were performed for clinically relevant variables. RESULTS The mD2 lymphadenectomy offered 3.03 dQALY over 5 years, outperforming D2 (2.62 dQALY) and D1 (2.37 dQALY). Monte Carlo simulations indicated that both mD2 and D2 lymph node dissection strategies outperformed D1 in 94.9% of simulations. Sensitivity analyses demonstrated that the mD2 approach would be less effective than D2 if the perioperative mortality rate of mD2 was greater than 6.9% (3.2% baseline). CONCLUSIONS Across modern series, the modified standard mD2 lymphadenectomy is an effective alternative to the traditional D2 lymphadenectomy for patients with gastric cancer. A D1-limited regional lymphadenectomy is not recommended during gastric cancer resection.

Abstract
Purpose Totally laparoscopic distal gastrectomy (TLDG) is now widely used for early gastric cancer patients, but the selection of a reconstruction method after TLDG is still controversial. Roux-en-Y gastrojejunostomy is increasingly used in expectation of less gastritis and alkaline reflux despite its technical difficulty. The uncut Roux-en-Y gastrojejunostomy (uRYGJ) retains the advantages of Roux-en-Y reconstruction but helps prevent Roux stasis syndrome. The present study aims to introduce a single surgeon's experience of TLDG with uRYGJ and analyze the learning curve and surgical outcomes. Methods We retrospectively reviewed the medical records of 124 consecutive patients who underwent TLDG with uRYGJ performed by a single surgeon between July 2014 and August 2015 at Asan Medical Center. The baseline characteristics and surgical outcomes were analyzed, and the learning curve was drawn based on the power-law model. Results The mean total operative time was 165 minutes, and the average length of hospital stay was 6.6 days. Complications included two cases of duodenal stump leakage, two intra-abdominal bleeding, two intra-abdominal fluid collection, one wound problem, two anastomotic strictures, 14 ileus, and no anastomotic leakage. There were five cases of endoscopically proven reflux gastritis/esophagitis and no Roux stasis syndrome. There were five recurrences and one mortality during the follow-up period. The learning curve leveled at the 15th case. Conclusion The results of our study showed the safety and feasibility of uRYGJ, and that the technical difficulty of the procedure can be overcome with a short learning curve for experienced surgeons.

Abstract
This retrospective study aimed to verify the short-term and long-term outcomes of elderly patients who underwent gastric resection for gastric cancer and to compare the results between younger and elderly patients. 222 Patients, who underwent gastrectomy between January 2005 and December 2014, were divided into 2 groups: ≤ 75 years old (group A) and > 75 years (group B). The groups were homogeneous except for more advanced pathological stage (p = 0.011) and higher number of comorbidities in group B (p < 0.001) and a higher rate of neoadjuvant or adjuvant complementary therapy in group A (p = 0.029 and p < 0.001). Perioperative morbidity rates were 38.7 and 65.5% (p = 0.001), and mortality rates were 2.5 and 7.9% (p = ns), respectively. The independent negative prognostic factors for morbidity were age older than 75 years [odds ratio (OR) 2.7], multiple organ resection (OR 2.4), and male gender (OR 1.8). The 36-month survival rates were 76.1% and 42.1% (p = 0.002) and disease-free survival rates were 85% and 76.3% (p = 0.017), respectively. Surgical indications should not be limited by age.

Abstract
Gastric cancer ranks the first in China among all gastrointestinal cancers in terms of incidence, and liver metastasis is the leading cause of death for patients with advanced gastric cancer. Tumor necrosis factor (TNF) is a cytokine commonly chosen as the target for gene therapy against cancers. The specific binding peptide pd20 of gastric cancer cells with a high potential for liver metastasis was fused with human TNF to obtain the pd20-TNF gene using DNA recombinant technique. The expression of the fusion protein was induced and the protein was purified. In vitro activity test showed that the fusion protein greatly improved the membrane permeability of liver cells in nude mice with liver metastasis from gastric cancer. The tumor implantation experiment in nude mice showed that the fusion protein effectively mitigated the cancer lesions. The results provide important clues for developing the drugs for targeted treatment of liver metastasis from gastric cancer.

Abstract
BACKGROUND The advantage of laparoscopic gastrectomy compared to open gastrectomy has been established in Asian patient series with early gastric cancer. However, its feasibility in Western European patients with locally advanced gastric cancer is unknown. METHODS Between 2006 and 2014 70 consecutive patients with advanced gastric cancer underwent laparoscopic gastrectomy with D2 lymph node dissection. A Billroth II reconstruction was performed after distal gastrectomy. In case of total gastrectomy a jejunal J-pouch reconstruction was performed. RESULTS Total gastrectomy was performed in 56 patients and distal gastrectomy in 14 patients. Perioperative chemotherapy was administered in 45/70 (64%) patients. A radical resection was achieved in 63/70 (90%). The median number of dissected lymph nodes was 17 (2-62). The median intraoperative blood loss was 305 (30-2700) milliliters. The median postoperative hospital stay was 11 (5-91) days. The 30-day mortality was 4.3%. CONCLUSIONS Laparoscopic gastrectomy can be performed in Western European patients with advanced gastric cancer and meets the oncologic standard with low intraoperative blood loss and short hospital stay.

Abstract
BACKGROUND Previous studies for surgical audit have focused on short-term outcomes, such as perioperative mortality. There has been no gold standard how to evaluate quality of care for long-term outcomes in surgical oncology. This preliminary study aims to propose a method for surgical audit targeting long-term outcome following gastrectomy for gastric cancer. METHODS We prospectively investigated a set of variables relating to physiologic conditions, tumor characteristics and operations in patients who underwent gastrectomy for gastric cancer between June 2005 and July 2008 in 18 referral hospitals in Japan. Overall survival (OS) is the endpoint. Cox hazard regression analysis was used to generate a model to predict OS. The calibration and discrimination power of the model were assessed using the Hosmer-Lemeshow (H-L) test and area under the receiver-operating characteristic curve (AUC), respectively. The ratio of observed-to-estimated 5-year OS rates (OE ratio) was defined as a measure of quality. RESULTS Among 762 patients analyzed, 697 (91%) completed the 5-year follow-up. The constructed model for OS exhibited a good discrimination power (AUC, 95% confidence interval 0.89, 0.86-0.91), which was significantly better than that for the UICC stage (0.81, 0.77-0.84). This model also demonstrated a good calibration power (H-L: χ(2) = 27.2, df = 8, P = 0.77). The OE ratios among the participating hospitals revealed no significant variation between 0.74 and 1.1. CONCLUSIONS The current study suggests the possibility of surgical audit for postoperative OS in gastric cancer. Further studies including high-volume centers will be necessary to validate this idea.

Abstract
Background A steady decline in gastric cancer mortality rate over the last few decades is observed in Western Europe. However it is still not clear if this trend applies to Eastern Europe where high incidence rate of gastric cancer is observed. Methods This was a retrospective non-randomized, single center, cohort study. During the study period 557 consecutive patients diagnosed with gastric cancer in which curative operation was performed met the inclusion criteria. The study population was divided into two groups according to two equal time periods: 01-01-1994 – 31-12-2000 (Group I – 273 patients) and 01-01-2001 – 31-12-2007 (Group II – 284 patients). Primary (five-year survival rate) and secondary (postoperative complications, 30-day mortality rate and length of hospital stay) endpoints were evaluated and compared. Results Rate of postoperative complications was similar between the groups, except for Grade III (Clavien-Dindo grading system for the classification of surgical complications) complications that were observed at significantly lower rates in Group II (26 (9.5%) vs. 11 (3.9%), p = 0.02). Length of hospital stay was significantly (p = 0.001) shorter (22.6 ± 28.9 vs. 16.2 ± 17.01 days) and 30-day mortality was significantly (p = 0.02) lower (15 (5.5%) vs. 4 (1.4%)) in Group II. Similar rates of gastric cancer related mortality were observed in both groups (92.3% vs. 90.7%). However survival analysis revealed significantly (p = 0.02) better overall 5-year survival rate in Group II (35.6%, 101 of 284) than in Group I (23.4%, 64 of 273). There was no difference in 5-year survival rate when comparing different TNM stages. Conclusions Gastric cancer treatment results remain poor despite decreasing early postoperative mortality rates, shortening hospital stay and improved overall survival over the time. Prognosis of treatment of gastric cancer depends mainly on the stage of the disease. Absence of screening programs and lack of clinical symptoms in early stages of gastric cancer lead to circumstances when most of the patients presenting with advanced stage of the disease can expect a median survival of less than 30 months even after surgery with curative intent.

Abstract
Gastric cancer surgical management differs between Eastern Asia and Western countries. Extended lymphadenectomy (D2) is the standard of care in Japan and South Korea since decades, while the majority of United States patients receive at most a limited lymphadenectomy (D1). United States and Northern Europe are considered the scientific leaders in medicine and evidence-based procedures are the cornerstone of their clinical practice. However, surgeons in Eastern Asia are more experienced, as there are more new cases of gastric cancer in Japan (107898 in 2012) than in the entire European Union (81592), or in South Korea (31269) than in the entire United States (21155). For quite a long time evidence-based medicine (EBM) did not solve the question whether D2 improves long-term prognosis with respect to D1. Indeed, eastern surgeons were reluctant to perform D1 even in the frame of a clinical trial, as their patients had a very good prognosis after D2. Evidence-based surgical indications provided by Western trials were questioned, as surgical procedures could not be properly standardized. In the present study we analyzed indications about the optimal extension of lymphadenectomy in gastric cancer according to current scientific literature (2008-2012) and surgical guidelines. We searched PubMed for papers using the key words “lymphadenectomy or D1 or D2” AND “gastric cancer” from 2008 to 2012. Moreover, we reviewed national guidelines for gastric cancer management. The support to D2 lymphadenectomy increased progressively from 2008 to 2012: since 2010 papers supporting D2 have achieved a higher overall impact factor than the other papers. Till 2011, D2 was the procedure of choice according to experts’ opinion, while three meta-analyses found no survival advantage after D2 with respect to D1. In 2012-2013, however, two meta-analyses reported that D2 improves prognosis with respect to D1. D2 lymphadenectomy was proposed as the standard of care for advanced gastric cancer by Japanese National Guidelines since 1981 and was adopted as the standard procedure by the Italian Research Group for Gastric Cancer since the Nineties. D2 is now indicated as the standard of surgical treatment with curative intent by the German, British and ESMO-ESSO-ESTRO guidelines. At variance American NCCN guidelines recommend a D1+ or a modified D2 lymph node dissection. In conclusion, D2 lymphadenectomy, originally developed by Eastern surgeons, is now becoming the procedure of choice also in the West. In gastric cancer surgery EBM is lagging behind national guidelines, rather than preceding and orienting them. To eliminate this lag, EBM should value to a larger extent Eastern Asian literature and should evaluate not only the quality of the study design but also the quality of surgical procedures.

Abstract
AIM BMI and the lymph node (LN) ratio can affect short- and long-term outcomes of patients with gastric cancer. PATIENTS & METHODS This study includes 104 consecutive patients with gastric adenocarcinoma who underwent curative gastrectomy divided in two groups: overweight group (group A) and normal weight group (group B). RESULTS We found that 53.4% of our patients were overweight (group A). The overall rate of postoperative complications was 16.3%, while mortality was 1%. Statistical analyses revealed that postoperative morbidity was significantly higher in group A (p < 0.05). Long-term survival was significantly higher in group B. Cox regression showed a statistically significant correlation between higher BMI and poor long-term survival after curative gastrectomy. Multivariate analysis has identified age and the LN ratios as independent prognostic factors of survival. CONCLUSION In this retrospective analysis, BMI and LN ratio were independently associated with survival in patients with gastric cancer. Further studies are needed to confirm our findings.

Abstract
Proximal gastrectomy (PG) has been introduced for patients who are preoperatively diagnosed with early gastric cancer located in the upper third of the stomach. In the present study, we compared the prognosis of patients who underwent PG with that of patients who underwent total gastrectomy (TG). Between 1997 and 2006, 51 patients were diagnosed with early gastric cancer located in the upper third of the stomach and underwent PG. In the same period, 35 patients were diagnosed with early gastric cancer and underwent TG. Of these, in 24 patients, the cancer was localized in the middle to upper part of the stomach, and 11 patients had multiple cancers. We compared the clinicopathologic differences and prognoses between the two groups. Significantly fewer lymph nodes were dissected in the PG group (mean, 18.2) than in the TG group (mean, 36.6;P < 0.001). Complications were detected in 17.6% of patients in the PG group and in 14.3% of patients in the TG group, which was not significant (P = 0.678). The overall and disease-specific 5-year survival rates in the 51 patients who underwent PG (88.7% and 97.1%, respectively) were not different from those in the 35 patients who underwent TG (87.6% and 93.4%; P = 0.971 and P = 0.553; respectively). These findings indicate that PG can be performed safely and may have various advantages compared with TG in terms of patients' daily lives.

Abstract
Although there is little evidence that bursectomy has clinical benefit, its continuing practice imposes evaluation of bursectomy-related adverse effects, especially pancreatic fistula and intestinal obstruction. The aims of this study were to provide a detailed description of the technique of bursectomy as standardized by the authors and determine if extended surgery for gastric cancer with additional bursectomy can be performed safely in Western population. A total of 72 consecutive patients of median age 76.4 years and mean ASA score grade 2.1, who submitted to D2 or D2+ gastrectomy with additional bursectomy for gastric adenocarcinoma, were prospectively studied. Bursectomy was associated with a median additional operative time of 41 min and a median additional blood loss of 65 ml. The post-operative morbidity rate was 19.4 %. Among various adverse events, pancreatic fistula was observed in three patients (4.2 %) and intestinal obstruction was observed in eight patients (11.1 %) including two cases of delayed gastric emptying, one case of afferent loop syndrome, one case of early postoperative adhesions and four cases of prolonged postoperative ileus. The in-hospital mortality rate was 1.4 %. D2 or D2+ gastrectomy with additional bursectomy can be safely performed in Western patients. Although the incidence of pancreatic fistula that we reported was low, the incidence of bursectomy-related intestinal obstruction was high and should always be kept in mind when performing extended surgery for gastric cancer.

Abstract
INTRODUCTION Gastric cancer is the fourth most common cancer worldwide. Predicting morbidity and mortality is important in deciding timing of surgery and type of surgery offered. APACHE II, POSSUM, and P-POSSUM are the most reliable scoring methods in use today. This is the first paper to evaluate the utility of all three scoring systems in China. METHODS We collected data on 851 patients (583 male and 268 female) who underwent surgery between 1991 and 2011. Physiological and pathological data was entered in spreadsheet format and analyzed using STATA version 11.0 to generate ROC curves for each scoring system. RESULTS In predicting mortality, P-POSSUM and POSSUM were most effective and APACHE II was ineffective. POSSUM predicted a higher morbidity risk than was actually encountered. Age and type of operation were found to be independent risk factors for mortality. DISCUSSION The utility of the APACHE II score in gastric cancer patients is limited. APACHE II is suitable for considering group versus individual effect. The POSSUM score is useful in general surgery, but needs improvement. We found the P-POSSUM score to be superior for morbidity and mortality prediction. P-POSSUM is useful for both the general population and for a specific cohort. The type of surgery is a key decision point for surgeons, and independently affects prognosis. Based upon these findings and clinical scoring systems, clinicians can develop individualized treatment algorithms.

Evaluation of modified Estimation of Physiologic Ability and Surgical Stress in gastric carcinoma surgery. Gastric Cancer 2012; 15:7-14. [PMID: 21538017 DOI: 10.1007/s10120-011-0052-2] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2011] [Accepted: 03/17/2011] [Indexed: 02/07/2023]
Abstract
BACKGROUND We recently modified our prediction scoring system "Estimation of Physiologic Ability and Surgical Stress" and have designated the current version mE-PASS. This scoring system has been designed to obtain predicted postoperative mortality rates before surgery and this study was performed to assess its usefulness in elective surgery for gastric carcinoma. METHODS We investigated seven variables for mE-PASS and evaluated the postoperative course in 3,449 patients who underwent elective surgery for gastric carcinoma in Japan between August 20, 1987 and April 9, 2007, in order to quantify the predicted in-hospital mortality rates (R). The calibration and discrimination power of R were assessed using the Hosmer-Lemeshow test and the area under the receiver operating characteristic curve (AUC), respectively. The ratios of observed-to-estimated mortality rates (OE ratios) were quantified as a measure of quality. RESULTS The overall postoperative morbidity and mortality rates were 19.0 and 2.0%, respectively. R demonstrated good power in calibration (χ(2) value, 12.5; df 8; P = 0.89) as well as discrimination (AUC, 95% confidence intervals: 0.80, 0.75-0.85). The OE ratios between hospitals ranged from 0.44 to 1.8. Overall, the OE ratios seemed to improve with time (OE ratio, 95% confidence intervals: 1.3, 0.73-2.4 for the early period between 1987 and 2000; 1.0, 0.59-1.7 for the middle period between 2001 and 2004; and 0.65, 0.36-1.2 for the late period between 2005 and 2007). CONCLUSION Based on these findings, mE-PASS might be useful for medical decision-making and for assessing the quality of care in elective surgery for gastric carcinoma.

Abstract
INTRODUCTION Gastric cancer is the second leading cause of cancer death in the world. The objective of this study was to present the clinical evaluation, treatment and outcome of 179 patients with gastric carcinoma in Zaria, Nigeria. METHODS Patients managed for histologically diagnosed gastric carcinoma were reviewed. The extent of surgical intervention was based on pre-operative and intra-operative staging balanced against the age and overall fitness of the patient. Mortality, morbidity and patient's survival were monitored. RESULTS There were 179 patients, with a male to female ratio of 1.4:1. Their mean age was 51 ± 6.3. Ten (5.6%) patients presented with early gastric cancer. Overall, 155(86.6%) patients had surgical intervention including gastric resection in 87 (56.1%). Of the gastrectomies , 28.7% were curative (R0). Postoperative complications were seen in 43(27.7%) patients. Postoperative mortality in 25(16.1%) patients was significantly associated with peritoneal metastasis (p<0.001), preoperative comorbidity (p<0.01) and age more than 60 years (p<0.03). The overall median survival was 13.6 months while 70.1% and 21.8% of patients that underwent gastrectomy survived for 1 and 5 years respectively. CONCLUSION Treatment of gastric cancer should be based on a reasonable choice of operation that must consider not only the survival benefits but also the surgical risks and postoperative quality of life.

Abstract
This study aims to analyze the scientific production about patients with gastric cancer submitted to gastrectomy and describe important aspects of nursing guidelines for these patients. An integrative review was carried out using Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Medical Literature Analysis and Retrieval System Online (MEDLINE) databases; twenty two articles were analyzed. Retrospective cross-sectional studies were the most frequent. The scientific production of nursing is numerically small in relation to the medical area. The results show that approaches related to pre and post-operative in gastrectomy for gastric cancer resection subsidize the knowledge of issues essential for nurses to promote efficient intervention for the recovery of such patients. There is still the need for further research on the practice of nursing in the guidelines of this kind of surgery.

Long-term results of tailored D(2) lymph node dissection after R(0) surgery for gastric cancer. Updates Surg 2011; 63:83-90.

Abstract
Implementation of extended lymph node dissection for gastric cancer in western non-specialized centers through tailoring its extent upon disease stage and patient comorbidities was suggested as a wise policy to reduce morbidity and mortality rates, albeit with a potential for undertreatment in elderly and/or comorbid patients. Current definition of R(0) resection for gastric cancer lacks consideration of treatment-related variables such as extended lymph node dissection. Few studies to date have tried to fill this gap in such a clinical context. A retrospective evaluation of factors influencing long-term results after R(0) surgery was done in a prospective series of a non-specialized western surgical unit during the implementation of D(2) lymphadenectomy. Univariate and multivariate analysis of 22 variables were performed on a prospective database of 233 consecutive R(0) resections performed by ten different surgeons in 10 years. Endpoint was disease-free survival calculated at 5 and at 10 years. Disease-free survival rates were independently influenced by age, American Society of Anesthesiologists (ASA) status and lymph node ratio. Subset analysis of the status at censor stratified for age and ASA status failed to identify any significant difference in disease recurrence rates. Lymph node ratio was the only treatment-related independent prognostic factor for long-term results after R(0) surgery for gastric cancer in the setting of a non-specialized western unit, where the extent of lymph node dissection needs to be tailored on the presence of comorbidities (ASA status).

Abstract
BACKGROUND Gastro-oesophageal surgery is associated with appreciable postoperative morbidity and mortality. POSSUM (Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity) and its related models P-POSSUM and O-POSSUM have been developed to predict such events in general surgery. The aim was to undertake the first systematic review of the use of these models in gastro-oesophageal surgery patients. METHODS An online database search was carried out from 1991 to December 2008. RESULTS Twenty-two published studies in gastro-oesophageal cancer surgery were identified. Twelve studies were found not to address the above aim, leaving ten relevant publications for analysis. Pooled data from these studies showed the weighted observed-to-expected ratio (O/E) for postoperative mortality using POSSUM (n = 1189), P-POSSUM (n = 2314), and O-POSSUM (n = 1755) was 0.37, 0.83, and 0.51, respectively. The weighted O/E for morbidity using POSSUM (n = 1038) was 0.86. CONCLUSION POSSUM and O-POSSUM most significantly overestimated postoperative mortality in gastro-oesophageal cancer patients. In contrast, P-POSSUM had the least overestimation and may be the most useful predictor of likely postoperative mortality in these patients.

Abstract
Gastric cancers are the second most common cause of cancer death worldwide. In the majority of countries, gastric tumours are diagnosed at advanced stages. The authors present the case of a patient with a T4 gastric tumour who underwent a multivisceral en bloc resection (liver segmentectomy, total gastrectomy, partial pancreatectomy) and D2 lymphadenectomy with spleen preservation. The aim of this report was to confirm that, for T4 gastric tumours, radical resection can be performed without splenectomy with minimal morbidity, and this procedure can improve long-term survival.
