Abstract
INTRODUCTION Body mass index (BMI) is often used in surgical settings to determine patients' risk of complications. In the context of gender-affirming care, BMI requirements for surgery can limit access to necessary care for larger-bodied people. There is a critical need to understand the association between BMI and postoperative outcomes for this population. METHODS A retrospective chart review was conducted using the first 250 consecutive gender-affirming masculinizing chest reconstructions performed between 2017 and 2021 at a large academic medical institution. The relationships between BMI, preoperative factors, and common postsurgical outcomes were assessed. RESULTS Average BMI at surgery was 27.5 ± 6.7 kg/m2. Increases in BMI were associated with longer drain stays, larger volume of tissue resected, higher likelihood of nipple grafts, and lower likelihood of periareolar surgery (all P < 0.0001). Simple logistic regression revealed that BMI increases were significantly related to the likelihood of experiencing dog ears in the intermediate term (P = 0.002). Multivariate logistic regression adjusted for common covariates (age, ethnicity, smoking status, asthma, autoimmune disorders, cardiovascular conditions, and mental health disorders) did not reveal any significant relationships between BMI and the likelihood of experiencing complications at any study point. CONCLUSIONS Masculinizing chest reconstruction is safe and satisfactory for young adult patients across the range of BMI, with significant differences in outcomes found only for esthetic complications (i.e., dog ears). Surgeons should inform patients with higher BMIs about what outcomes to expect but higher BMI should not preclude surgery access.

Kang MK, Lee H. Impact of malnutrition and nutritional support after gastrectomy in patients with gastric cancer. Ann Gastroenterol Surg 2024; 8:534-552. [PMID: 38957563 PMCID: PMC11216795 DOI: 10.1002/ags3.12788] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 02/03/2024] [Accepted: 02/24/2024] [Indexed: 07/04/2024] Open
Abstract
Malnutrition, characterized by altered body composition and impaired function, is particularly prevalent among gastric cancer patients, affecting up to 60% of them. Malnutrition in these patients can manifest both before and after surgery, due to factors such as gastric outlet obstruction, cancer cachexia, and anatomical changes. Notably, total gastrectomy (TG) presents the most significant nutritional challenges. However, function-preserving gastrectomy, such as pylorus-preserving gastrectomy (PPG) and proximal gastrectomy (PG), have shown promise in improving nutritional outcomes. Effective nutritional risk screening and assessment are vital for identifying patients at risk. Nutritional support not only improves nutritional parameters but also reduces complications, enhances quality of life (QoL) and survival rates. Those unable to maintain more than 50% of the recommended intake for over 7 days are recommended for nutritional support. Common methods of nutritional support include oral nutrition supplements (ONS), enteral nutrition (EN), or parenteral nutrition (PN) depending on the patient's status. Effect of perioperative nutritional support remains controversial. Preoperative interventions including ONS and PN have shown mixed results, with selective benefits in patients with sarcopenia or hypoalbuminaemia, while impact of EN in gastric outlet obstruction patients have been positive. In contrast postoperative support appears to be consistent. Tube feeding after TG has shown improvements, and ONS have been effective in reducing weight loss and improving nutritional biomarkers. PN was also associated with benefits such as weight maintenance and QoL. This review explores the mechanisms, assessment, and clinical impact of malnutrition, emphasizing the importance of nutritional support in gastric cancer patients undergoing gastrectomy.

Abstract
It is well established that the preoperative nutritional status of gastric cancer (GC) patients significantly affects the prognosis of the operated patients, their overall survival, as well as the disease-specific survival. Existing data support that preoperative assessment of nutritional status and early correction of nutritional deficiencies exert a favorable effect on early postoperative outcomes. A variety of relevant indices are used to assess the nutritional status of GC patients who are candidates for surgery. The guidelines of almost all international organizations recommend the use of oral enteral nutrition (EN). Oncologically acceptable types of gastrectomy and methods of patient rehabilitation should take into account the expected postoperative nutritional status. The majority of data support that perioperative EN reduces complications and hospital stay, but not mortality. Oral EN in the postoperative period, albeit in small amounts, helps to reduce the weight loss that is a consequence of gastrectomy. Iron deficiency with or without anemia and low serum levels of vitamin B12 are common metabolic sequelae after gastrectomy and should be restored. EN also significantly helps patients undergoing neoadjuvant or adjuvant antineoplastic therapy. The occurrence of the so-called "postgastrectomy syndromes" requires dietary modifications and drug support. This review attempts to highlight the benefits of EN in GC patients undergoing gastrectomy and to emphasize the type of necessary nutritional management, based on current literature data.

Abstract
In patients scheduled for surgery, nutritional disorders worsen during the perioperative period, which is often a risk factor for postoperative complications. The aim of the study was to determine relationship between the preoperative nutritional status of elderly people with stomach, pancreatic and colon cancer and the incidence of postoperative complications and the length of hospital stay. The study included 143 patients with gastrointestinal cancer, aged 65-68, qualified for surgery. Mini Nutritional Assessment, body mass index questionnaires and medical records were used. Malnutrition was found in 9.8%, and a risk of malnutrition in 53.5% of the respondents. Body mass index showed overweight in 28% and obesity in 14% of the patients. Complications occurred in all types of nutritional status, the most common were those requiring intensive care unit treatment (36.8%), pancreatic and biliary fistulas (29.4%) and surgical site infections (58.2%). Gastric cancer patients at risk of malnutrition stayed longer in the hospital. Postoperative complications and longer hospital stays were observed more frequently in cases of overweight, obesity, malnutrition and its risk. Disturbances in the nutritional status, in the form of malnutrition and its risk, as well as overweight and obesity, determined more frequent occurrence of postoperative complications and longer hospital stay.

Abstract
PURPOSE The increasing availability of clinical imaging tests (especially CT and MRI) that directly quantify adipose tissue has led to a rapid increase in studies examining the relationship of visceral, subcutaneous, and overall adiposity to cancer survival. To summarize this emerging body of literature, we conducted a systematic review and meta-analysis of imaging-measured as well as anthropometric proxies for adipose tissue distribution and cancer survival across a wide range of cancer types. METHODS Using keywords related to adiposity, cancer, and survival, we conducted a systematic search of the literature in PubMed and MEDLINE, Embase, and Web of Science Core Collection databases from database inception to 30 June 2021. We used a random-effect method to calculate pooled hazard ratios (HR) and corresponding 95% confidence intervals (CI) within each cancer type and tested for heterogeneity using Cochran's Q test and the I2 test. RESULTS We included 203 records for this review, of which 128 records were utilized for quantitative analysis among 10 cancer types: breast, colorectal, gastroesophageal, head and neck, hepatocellular carcinoma, lung, ovarian, pancreatic, prostate, and renal cancer. We found that imaging-measured visceral, subcutaneous, and total adiposity were not significantly associated with increased risk of overall mortality, death from primary cancer, or cancer progression among patients diagnosed with these 10 cancer types; however, we found significant or high heterogeneity for many cancer types. For example, heterogeneity was similarly high when the pooled HRs (95% CI) for overall mortality associated with visceral adiposity were essentially null as in 1.03 (0.55, 1.92; I2 = 58%) for breast, 0.99 (0.81, 1.21; I2 = 71%) for colorectal, versus when they demonstrated a potential increased risk 1.17 (0.85, 1.60; I2 = 78%) for hepatocellular carcinoma and 1.62 (0.90, 2.95; I2 = 84%) for renal cancer. CONCLUSION Greater adiposity at diagnosis (directly measured by imaging) is not associated with worse survival among cancer survivors. However, heterogeneity and other potential limitations were noted across studies, suggesting differences in study design and adiposity measurement approaches, making interpretation of meta-analyses challenging. Future work to standardize imaging measurements and data analyses will strengthen research on the role of adiposity in cancer survival.

Abstract
BACKGROUND/OBJECTIVES This study aimed to investigate cancer-specific survival (CSS) and associated risk factors in elderly gastric cancer (EGC) patients. SUBJECTS/METHODS EGC patients (≥ 70 yrs) who underwent curative gastrectomy between January 2013 and December 2017 at our hospital were included. Clinicopathologic characteristics and survival data were collected. Receiver operating characteristic (ROC) analysis was used to extract the best cutoff point for body mass index (BMI). A Cox proportional hazards model was used to determine the risk factors for CSS. RESULTS In total, 290 EGC patients were included, with a median age of 74.7 yrs. The median follow-up time was 31 (1–77) mon. The postoperative 1-yr, 3-yr and 5-yr CSS rates were 93.7%, 75.9% and 65.1%, respectively. Univariate analysis revealed risk factors for CSS, including age (hazard ratio [HR] = 1.08; 95% confidence interval [CI], 1.01–1.15), intensive care unit (ICU) admission (HR = 1.73; 95% CI, 1.08–2.79), nutritional risk screening (NRS 2002) score ≥ 5 (HR = 2.33; 95% CI, 1.49–3.75), and preoperative prognostic nutrition index score < 45 (HR = 2.06; 95% CI, 1.27–3.33). The ROC curve showed that the best BMI cutoff value was 20.6 kg/m2. Multivariate analysis indicated that a BMI ≤ 20.6 kg/m2 (HR = 2.30; 95% CI, 1.36–3.87), ICU admission (HR = 1.97; 95% CI, 1.17–3.30) and TNM stage (stage II: HR = 5.56; 95% CI, 1.59–19.43; stage III: HR = 16.20; 95% CI, 4.99–52.59) were significantly associated with CSS. CONCLUSIONS Low BMI (≤ 20.6 kg/m2), ICU admission and advanced pathological TNM stages (II and III) are independent risk factors for CSS in EGC patients after curative gastrectomy. Nutrition support, better perioperative management and early diagnosis would be helpful for better survival.

Abstract
Body mass index (BMI) requirements for gender affirmation surgery (GAS) are ubiquitous and vary across providers. Requirement variation is not surprising given little data to suggest an association between BMI and GAS outcomes. Implementation of subjective BMI requirements limits access to GAS and negatively impacts patient health and safety. We outline the literature on BMI and GAS outcomes, discuss clinical utility of GAS, and summarize dangers of prescribing weight loss as a prerequisite for surgery. We propose that providers use empirically supported indices of health and comorbidity instead of BMI to determine surgical eligibility for all patients considering GAS.

Abstract
Aim This study was designed to investigate the prognostic effect of preoperative body mass index (BMI) for Type 2 diabetes mellitus (T2DM) patients with non-metastasis gastric cancer (GC) who underwent D2 gastrectomy. Methods T2DM patients with pT1–4bN0–3bM0 GC were retrospectively collected in Department of Gastrointestinal Surgical Oncology, Fujian Cancer Hospital & Fujian Medical University Cancer Hospital from January, 2000 to December, 2010. These patients underwent D2 radical resection of the stomach combined with regional lymphadenectomy. Chi-square test was used to analyze unordered categorical variables and ranked data, followed by Kaplan–Meier analysis as well as Cox regression models to detect risk factors for survival outcomes. In addition, the cut-off point was determined by the X-tile program. All analyses were carried out using survival package of R and SPSS Software. Results A total of 302 T2DM patients with pT1–4bN0–3bM0 GC were collected and analyzed. The cut-off points of BMI, identified by the X-tile program, was 19 kg/m2. Patients with low BMI (< 19 kg/m2) had a higher percentage of advanced T stage (T4a and T4b), more advanced TNM stage (stage IIIA, IIIB and IIIC), and more elevated level of serum carcinoembryonic antigen (CEA), compared to those with high BMI (> 19 kg/m2) (all P < 0.05). In the low BMI subgroup, the 5-year overall survival rate was 39.02%, which was as high as 58.11% in the high BMI subgroup (P < 0.05). In the multivariate Cox regression model revealed that IIIC stage (OR = 3.101), N3b stage (OR = 3.113) were the most important prognostic indicators, followed by pretreatment BMI (OR = 2.136). Conclusion Low preoperative BMI (< 19 kg/m2) was a poor prognostic marker for T2DM patients with pT1–4bN0–3bM0 GC.

Abstract
OBJECTIVE The aim is to explore the prediction effect of 5 machine learning algorithms on peritoneal metastasis of gastric cancer. METHODS 1080 patients with postoperative gastric cancer were divided into a training group and test group according to the ratio of 7:3. The model of peritoneal metastasis was established by using 5 machine learning (gbm(Light Gradient Boosting Machine), GradientBoosting, forest, Logistic and DecisionTree). Python pair was used to analyze the machine learning algorithm. Gbm algorithm is used to show the weight proportion of each variable to the result. RESULT Correlation analysis showed that tumor size and depth of invasion were positively correlated with the recurrence of patients after gastric cancer surgery. The results of the gbm algorithm showed that the top 5 important factors were albumin, platelet count, depth of infiltration, preoperative hemoglobin and weight, respectively. In training group: Among the 5 algorithm models, the accuracy of GradientBoosting and gbm was the highest (0.909); the AUC values of the 5 algorithms are gbm (0.938), GradientBoosting (0.861), forest (0.796), Logistic(0.741) and DecisionTree(0.712) from high to low. In the test group: among the 5 algorithm models, the accuracy of forest, DecisionTree and gbm was the highest (0.907); AUC values ranged from high to low to gbm (0.745), GradientBoosting (0.725), forest (0.696), Logistic (0.680) and DecisionTree (0.657). CONCLUSION Machine learning can predict the peritoneal metastasis in patients with gastric cancer.

Abstract
The impact of body mass index (BMI) on surgical outcomes has previously been studied in relation to several oncological procedures. Regarding gastric cancer surgery, published results have been contradicting in terms of degree of technical difficulty, risk of postoperative complications and survival. In an attempt to clarify these issues, we performed a meta-analysis to evaluate the impact of obesity (defined as BMI ≥ 30 kg/m2) on outcomes after gastrectomy for gastric cancer. The meta-analysis was performed according to the PRISMA guidelines. Eligible studies were identified through search of PubMed, EMBASE, Web of Science and Cochrane Library databases. Quality assessment was performed using the Newcastle-Ottawa scale. The meta-analysis was conducted using random-effects modeling. A total of 11 studies with 13 538 patients were eligible for analysis. Obesity was associated with a significantly longer operation time (WMD = 19.38 min, 95% CI 12.72-26.04; p < 0.001), increased risk of overall complications (RR = 1.23, 95% CI 1.06-1.42; p = 0.005) and pulmonary complications (RR = 3.81, 95% CI 2.24-6.46; p < 0.001). These findings remained irrespective type of surgery (laparoscopic vs. open) and type of gastrectomy. No differences were found regarding blood loss, number of resected lymph nodes, anastomotic leakage, hospital stay, 30-day mortality and 5-year overall survival. The conclusion of the current meta-analysis is that high BMI in gastric cancer patients is associated with longer operative time and more frequent overall postoperative complications. However, it has no negative impact on survival, indicating that gastrectomy is a safe procedure for this group of patients.

[PMID: 33971589 DOI: 10.1016/j.clinimag.2021.03.035] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Revised: 03/20/2021] [Accepted: 03/27/2021] [Indexed: 11/19/2022]
Abstract
PURPOSE To evaluate the association of visceral adiposity measured on computed tomography (CT) in preoperative period with lymph node (LN) metastasis and overall survival in gastric adenocarcinoma patients. METHODS Preoperative CT scans of 246 gastric adenocarcinoma patients who did not receive neoadjuvant chemoradiotherapy were evaluated. Visceral fat area (VFA), subcutaneous fat area (SFA) and Total fat area (TFA), VFA/TFA ratio were quantified by CT. VFA/TFA > 29% was defined as visceral obesity. The differentiation, t-stage, n-stage and the number of harvested-metastatic LNs were noted. The maximum thickness of tumor and localization were recorded from CT. Chi-square, Student's t-test, multiple Cox regression, Spearman's correlation coefficient, and Kaplan-Meier algorithm were performed. RESULTS The overall survival (OS) rates and N-stage were not different significantly between viscerally obese and non-obese group (p = 0.994, p = 0.325). The number of metastatic LNs were weakly inversely correlated with VFA (r = -0.144, p = 0.024). Univariate analysis revealed no significant association between visceral obesity and OS or LN metastasis (p = 0.377, p = 0.736). In multivariate analyses, OS was significantly associated with poorly differentiation (HR = 1.72, 95% CI =1.04-2.84, p = 0.035), higher pathologic T and N stage (T4 vs T1 + T2 HR = 2.67, 95% CI =1.18-6.04, p = 0.019; T3 vs T1 + T2 HR = 1.98, 95% CI = 0.90-4.33, p = 0.089; N3b vs N0 HR = 2.97, 95% CI1.45-6.0, p = 0.003; N3 (3a+ 3b) vs N0 HR = 2.24 95% CI =1.15-4.36, p = 0.018). CONCLUSION Visceral obesity may not be a prognostic factor in resectable gastric adenocarcinoma patients.

Abstract
Genetic and epigenetic alterations have been under concentrated investigations for many years in order to unearth the molecules regulating human cancer pathogenesis. However, the identification of a wide range of dysregulated genes and their protein products has raised a question regarding how the results of this large collection of alterations could converge into a formation of one malignancy. The answer may be found in the signaling cascades that regulate the survival and metabolism of the cells. Aberrancies of each participant molecule of such cascades may well result in augmented viability and unlimited proliferation of cancer cells. Among various signaling pathways, the phosphatidylinositol-3-kinase (PI3K) axis has been shown to be activated in about one-third of human cancers. One of the malignancies that is mostly affected by this axis is gastric cancer (GC), one of the most fatal cancers worldwide. In the present review, we aimed to illustrate the significance of the PI3K/Akt/mTOR axis in the pathogenesis of GC and also provided a wide perspective about the application of the inhibitors of this axis in the therapeutic strategies of this malignancy.

Abstract
PURPOSE This study aimed to examine the impact of preoperative body mass index (BMI) on postoperative activities of daily living (ADL) and clinical outcomes in older patients who underwent curative gastrectomy. METHODS This was a retrospective observational study using a nationwide inpatient database in Japan. The study included 1769 patients with gastric cancer, aged ≥ 65 years old, who underwent gastrectomy. BMI was defined as per the World Health Organization classifications for Asian populations. Primary outcome was ADL at discharge, assessed by Barthel index. Secondary outcomes included postoperative complications and length of hospital stay. RESULTS Patients analyzed included 890 (50.3%) aged 65-74 years, 745 (42.1%) aged 75-84 years, and 134 (7.6%) aged ≥ 85 years; 71.5% were male. According to BMI classification, 11.9% patients were considered underweight (< 18.5 kg/m2), 46.7% were in the standard range (18.5 to < 23 kg/m2), 34.1% were classified as overweight (23-27.5 kg/m2), and 7.3% were in the obese group (≥ 27.5 kg/m2). In multivariate analysis, a significant association was observed between BMI and Barthel index scores (underweight group: standardized coefficient, - 0.040; compared with standard group; p = 0.013), postoperative complication (obese group: odds ratio, 1.562; compared with standard group; p = 0.034), and length of hospital stay (obese group: standardized coefficient, 0.047; compared with standard group; p = 0.019). CONCLUSION Perioperative management with a focus on BMI is important in older patients undergoing elective curative gastrectomy.

Geriatric nutritional risk index predicts cancer prognosis in patients with local advanced rectal cancer undergoing chemoradiotherapy followed by curative surgery. World J Surg Oncol 2021; 19:34. [PMID: 33516219 PMCID: PMC7847581 DOI: 10.1186/s12957-021-02139-z] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Accepted: 01/19/2021] [Indexed: 12/18/2022] Open
Abstract
Aim The clinical significance of the geriatric nutritional risk index (GNRI) in locally advanced rectal cancer (LARC) patients undergoing preoperative chemoradiotherapy (CRT) followed by curative surgery has not been comprehensively evaluated. Methods This retrospective study enrolled 93 LARC patients diagnosed with clinical lymph node metastasis. The GNRI formula was as follows: 1.489 × albumin (g/l) + 41.7 × current weight/ideal weight. Patients were categorized as GNRI low (GNRI < 104.25) or high (GNRI > 104.25) according to the receiver operating characteristic (ROC) curve for survival analysis. The impact of GNRI status on the prognostic outcomes of curative surgery for LARC was examined. Results There were 55 (59.14%) and 38 (40.86%) patients in the GNRI high and low groups, respectively. Of the investigated demographic factors, age, pathological tumor invasion, and presence of recurrence were significantly associated with the GNRI value. In Kaplan–Meier analysis, overall survival (OS) and disease-free survival (DFS) were significantly shorter in the GNRI low group (OS: p = 0.00020, DFS: p = 0.0044, log-rank test). Multivariate analysis using a Cox proportional hazards model showed that a low GNRI was an independent risk factor for poor OS (hazard ratio (HR) = 3.22; 95% confidence interval (CI), 1.37–8.23; p = 0.0068) and DFS (HR = 2.32; 95%CI = 1.15–4.79; p = 0.018). Although use of adjuvant therapy has no impact on prognosis (OS: p = 0.26, DFS: p = 0.29), low GNRI showed shorter OS and DFS in patients with pathological lymph node metastasis [ypN(+)] (OS: p = 0.033, DFS: p = 0.032, log-rank test). Conclusions GNRI is a useful marker for LARC patients diagnosed with clinical lymph node metastasis and treated by preoperative CRT followed by curative surgery. GNRI is a useful tool to identify high risk of recurrence for improving the survival in LARC patients.

Abstract
Purpose This study aimed to evaluate the relationship between the body mass index (BMI) and the short-term outcomes of laparoscopic total gastrectomy (LTG). Subjects and Methods Data of patients who underwent LTG for gastric cancer at six institutions between 2004 and 2018 were retrospectively collected. The patients were classified into three groups: low BMI (<18.5 kg/m2), normal BMI (≥18.5 and <25 kg/m2) and high BMI (≥25 kg/m2). In these patients, clinicopathological variables were analysed using propensity score matching for age, sex, the American Society of Anaesthesiologists physical state, clinical stage, surgical method, D2 lymph node dissection, combined resection of other organs, anastomosis method and jejunal pouch reconstruction. The surgical results and post-operative outcomes were compared among the three groups. Results A total of 82 patients were matched in the analysis of the low BMI and normal BMI groups. There were no differences in operative time (P = 0.693), blood loss (P = 0.150), post-operative complication (P = 0.762) and post-operative hospital stay (P = 0.448). In the analysis of the normal BMI and high BMI groups, 208 patients were matched. There were also no differences in blood loss (P = 0.377), post-operative complication (P = 0.249) and post-operative hospital stay (P = 0.676). However, the operative time was significantly longer in the high BMI group (P = 0.023). Conclusions Despite the association with a longer operative time in the high BMI group, BMI had no significant effect on the surgical outcomes of LTG. LTG could be performed safely regardless of BMI.

Abstract
BACKGROUND The advanced lung cancer inflammation index (ALI) has recently been shown as a prognostic marker for several cancers. However, its predictive value for surgical and oncological outcomes in gastric cancer (GC) remains unclear. METHODS We retrospectively reviewed the preoperative ALI in 620 GC patients receiving gastrectomy to elucidate the prognostic value for overall survival (OS) and disease-free survival (DFS) and to clarify its predictive value for perioperative risk of surgical site infection (SSI) in GC patients. Propensity score matching (PSM) analysis was also conducted to certify these potentials of preoperative ALI. RESULTS Preoperative low ALI was significantly correlated with advanced tumor-node-metastasis stage classification. Patients with low ALI showed poorer OS (p < 0.0001) and DFS (p < 0.0001) compared to those with high ALI, and multivariate analysis showed that decreased ALI was an independent prognostic factor for OS [hazard ratios of 1.59; 95% confidence interval (CI) of 1.15-2.19, p = 0.006]. Meanwhile, preoperative low ALI was also an independent risk factor for overall SSI [odds ratio (OR) of 2.04, 95% CI of 1.24-3.35, p = 0.005] or organ-space SSI (OR of 2.69, 95% CI of 1.40-5.23, p = 0.003). We further conducted PSM analysis and verified all of these findings in the PSM cohort. CONCLUSION Quantification of preoperative ALI can identify patients with high risk of adverse perioperative and oncological outcomes in GC patients.

Abstract
BACKGROUND Robotic distal gastrectomy (RDG) has been increasingly used for the treatment of gastric cancer in recent year. However, whether RDG could reduce the morbidity when compared to laparoscopic distal gastrectomy (LDG) remains controversial. This study aimed to compare the morbidity and short-term surgical outcomes of RDG and LDG for gastric cancer and identify the related risk factors. METHODS Between March 2010 and August 2019, consecutive patients undergoing RDG or LDG (519 and 957 patients, respectively) at our institution were included in this study. Postoperative complications were stratified according to the Clavien-Dindo (C-D) classification. We performed one-to-one propensity score matching (PSM) analysis, and evaluated postoperative morbidity and short-term surgical outcomes in PSM 1032 patients undergoing RDG or LDG. RESULTS After PSM, the two groups were well-balanced. The mean blood loss of the RDG group was about 27 mL less than that of the LDG group (112.1 vs 139.0 mL, P < 0.001). The RDG group had more retrieved lymph nodes than that in the LDG group (32.7 v 30.2, P < 0.001). The RDG group showed a similar overall (9.9% vs 10.7%, P = 0.682), severe (2.7% vs 3.7%, P = 0.376), local (5.6% vs 5.2%, P = 0.783), and systemic complication rates (5.4% vs 6.0%, P = 0.688). There were no significant differences in mortality between the two groups (RDG 0% vs LDG 0.2%, P = 1.000). Subgroup analyses showed no significant differences in most stratified parameters. Age > 65 years and ASA III were identified as two major risk factors for complications. CONCLUSION RDG could be a safe and feasible in treating gastric cancer compared to LDG. However, we did not observe significant reduction in postoperative complications of RDG compared with LDG, although the use of robotic system is assumed to provide a technically superior operative environment.

Obesity is a major health issue in the modern world population and a risk factor for surgical procedures. This study examined perioperative and oncologic results of gastrectomy in obese patients diagnosed with gastric cancer. BMI ≥30 kg/m2 was used to designate obesity. Five hundred and one patients were operated throughout the study period (2009–2018). The outcomes in obese patients (n = 205) were compared with those with normal weight (n = 171) and overweight (n = 125). The mean BMI was significantly different between the groups: 21.9 versus 26.7 versus 33.3 kg/m2 ( P < 0.01), respectively. Obesity was associated with higher incidence of comorbidities, longer operative time, and increased blood loss. Postoperative and short-term oncologic outcomes were similar. Median follow-up was 24 months with similar recurrence rates in the three groups. Median survival was comparable between the normal weight, overweight, and obese patients—36 (27–45) versus 42 (30–53) versus 32 (17–47) months, respectively ( P = 0.63). Obesity itself does not deteriorate the surgical outcomes of gastrectomy in patients with gastric cancer. Although technically demanding in obese patients, adequate lymph node yield and satisfactory long-term oncologic outcomes can be achieved in this group.

Abstract
Background Elderly patients with gastric cancer (GC) are at increased risk of infectious complications following gastrectomy. A limited set of risk factors has been identified to predict complications in these patients. To improve the safety of gastrectomy in this population, we investigated the incidence of infectious complications and associated clinicopathologic, nutritional and surgical risk factors in a cohort of elderly patients with GC. Methods Elderly GC patients (≥70 years) who underwent gastrectomy between January 2013 and December 2017 in Peking Union Medical College Hospital were included in the study. Clinicopathologic data were collected retrospectively. Severity of complications was classified using the Clavien–Dindo system. Infectious complications were assessed based on clinical diagnosis of health care-associated infection as defined by the US Centers for Disease Control and Prevention. Multivariate logistic regression analyses were performed to determine the risk factors for infectious complications. Results Three hundred thirty-one consecutive patients were included, with a median age of 74 years (range 70–88). The rate of surgical morbidity was 37.5% and the mortality rate was 1.2%. The incidence of infectious complications was 19.6%, with the most common infectious complication being pulmonary infection (11.5%). Preoperative weight loss ≥5% (odds ratio [OR] = 2.21; 95% CI, 1.15–4.28; p = 0.018), Charlson comorbidity index score ≥3 (OR = 2.83; 95% CI, 1.30–6.16; p = 0.009) and preoperative hsCRP level ≥10 mg/L (OR = 2.48; 95% CI, 1.14–5.38; p = 0.022) were independently associated with infectious complications. Conclusion Preoperative weight loss, elevated hsCRP level and comorbidity burden can be used to predict postoperative infectious complications in elderly GC patients. It is recommended to pay more attention to the treatment of elderly GC patients with these risk factors.

World J Gastroenterol 2020; 26:1613-1627. [PMID: 32327910 PMCID: PMC7167420 DOI: 10.3748/wjg.v26.i14.1613] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2019] [Revised: 03/05/2020] [Accepted: 03/19/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Lifestyle factors such as body mass index (BMI), alcohol drinking, and cigarette smoking, are likely to impact the prognosis of gastric cancer, but the evidence has been inconsistent.
AIM To investigate the association of lifestyle factors and long-term prognosis of gastric cancer patients in the China National Cancer Center.
METHODS Patients with gastric cancer were identified from the China National Cancer Center Gastric Cancer Database 1998-2018. Survival analysis was performed via Kaplan-Meier estimates and Cox proportional hazards models.
RESULTS In this study, we reviewed 18441 cases of gastric cancer. Individuals who were overweight or obese were associated with a positive smoking and drinking history (P = 0.002 and P < 0.001, respectively). Current smokers were more likely to be current alcohol drinkers (61.3% vs 10.1% vs 43.2% for current, never, and former smokers, respectively, P < 0.001). Multivariable results indicated that BMI at diagnosis had no significant effect on prognosis. In gastrectomy patients, factors independently associated with poor survival included older age (HR = 1.20, 95%CI: 1.05-1.38, P = 0.001), any weight loss (P < 0.001), smoking history of more than 30 years (HR = 1.14, 95%CI: 1.04-1.24, P = 0.004), and increasing pTNM stage (P < 0.001).
CONCLUSION In conclusion, our results contribute to a better understanding of lifestyle factors on the overall burden of gastric cancer and long-term prognosis. In these patients, weight loss (both in the 0 to 10% and > 10% groups) but not BMI at diagnosis was related to survival outcomes. With regard to other factors, smoking history of more than 30 years conferred a worse prognosis only in patients who underwent gastrectomy. Extensive efforts are needed to elucidate mechanisms targeting the complex effects of lifestyle factors.

Abstract
BACKGROUND Obesity has been reported to be a prognostic factor for many diseases in epidemiological studies; however, the results of studies examining the relationship between obesity and gastric cancer (GC) prognosis are inconsistent. METHODS A total of 460 patients with Stage II and III GC who underwent open R0 gastrectomy were included. Age, sex, body mass index (BMI classified into < 18.5, 18.5-25, and ≥ 25 kg/m2), stage, and postoperative adjuvant chemotherapy were analyzed to investigate the correlation with relapse-free survival (RFS). RESULTS Five-year RFS was 51% for the study patients. Five-year RFS values were 47.6%, 54.3%, and 40.1% for patients with BMI < 18.5, 18.5-25, and ≥ 25 kg/m2, respectively. The forest plot for relapse risk according to BMI showed a U shape. Multivariate analysis for RFS showed significant differences in stage and BMI; the hazard ratio for recurrence in patients with BMI ≥ 25 kg/m2 was 1.42 (95% confidence interval: 1.01-2.02, p = 0.0423) with reference to patients with BMI < 25 kg/m2. BMI ≥ 25.0 was associated with longer operation times, more blood loss, fewer lymph nodes dissected, more frequent postoperative surgical site infection, and intra-abdominal abscesses. CONCLUSIONS BMI ≥ 25 kg/m2 is an unfavorable prognostic factor for patients who underwent gastrectomy for Stage II and III GC.

Abstract
BACKGROUND Postoperative complications after gastric cancer resection vary in different series and they might have a significant impact in long-term outcomes. Our aim was to build a prediction rule on gastric cancer patients' overall and major morbidity risks. METHODS This retrospective study included 1223 patients from a single center who were resected between 1992 and 2016. Overall and major morbidity predictors were identified through multiple logistic regression. Models' performances were assessed through discrimination, calibration, and cross-validation, and nomograms were constructed. RESULTS The mean age was 61.3-year old and the male gender was more frequent (60%). The most common comorbidities were hypertension (HTN), diabetes, and chronic obstructive pulmonary disease (COPD). A D2-distal gastrectomy was the most frequent procedure and 87% of all lesions were located in the middle or distal third. Age, COPD, coronary heart disease, chronic liver disease, pancreatic resection, and operative time were independent predictors of overall and major morbidity. The extent of resection and splenectomy was associated with overall events and HTN with major ones. Both models were very effective in predicting events among patients at higher risk. CONCLUSIONS The overall and major morbidity models and nomograms included clinical- and surgical-related data that were very effective in predicting events, especially for high-risk patients.

Abstract
INTRODUCTION Preoperative body weight and nutritional status are related to prognosis in patients with gastric cancer; however, the prognostic impact of postoperative in these variables is unclear. We aimed to investigate the association of preoperative/postoperative body mass index (BMI) and prognostic nutritional index (PNI) with prognosis in patients with gastric cancer. MATERIALS AND METHODS We retrospectively 1868 patients with stage II/III gastric cancer treated with gastrectomy between January 2006 and December 2010. We divided the populations into 3 groups according to BMI; underweight, normal, and overweight. Patients were divided into 3 groups according to BMI (underweight, normal-weight, overweight). PNI was classified into low and high (cutoff value; 49.7). The association of preoperative BMI/PNI and their changes (6 months postoperatively) with clinicopathologic characteristics were evaluated. RESULTS Preoperative underweight and low PNI were related to poor prognosis (log-rank p < 0.001 for both). There was a positive correlation between preoperative BMI and PNI (mean preoperative PNI: 51.13 [underweight], 53.37 [normal-weight], and 55.16 [overweight]; p < 0.001). Preoperative BMI and PNI were independent prognostic factors for disease-free survival along with age and TNM stage (p < 0.001 for both). BMI changes from normal-weight to underweight and from overweight to normal/underweight were related to poor prognosis (log-rank p = 0.021 and p = 0.013, respectively). PNI changes were related to prognosis in both the preoperative low and high PNI groups (p < 0.001 and p = 0.019, respectively). CONCLUSION Preoperative BMI and PNI and their postoperative changes are related to prognosis in patients with stage II/III gastric cancer. Careful nutritional intervention after gastrectomy can improve prognosis.

Abstract
AIMS AND METHODS This multicenter retrospective study aims to evaluate the correlations between Body Weight Loss (BWL), Body Mass Index (BMI) and clinical outcomes (ORR, PFS, and OS) of advanced gastric cancer (aGC) patients treated with second-line ramucirumab-based therapy in a "real-life" setting. RESULTS From December 2014 to October 2018, 101 consecutive aGC patients progressed to a first-line chemotherapy were treated with ramucirumab alone (10.9%) or in combination with paclitaxel (89.1%). Median BMI was 21.2 kg/m2 and mBWL since first-line treatment commencement was 4.5%. Among 53 patients who underwent primary tumor resection (PTR), 73.6% experienced BWL, while 26.4% did not experience BWL (p = 0.0429). Patients who underwent PTR had a significantly higher probability of experiencing BWL (yes vs no) [OR = 2.35 (95% CI 1.02-5.42), p = 0.0439]. Among the 89 evaluable patients, ORR was 26.9% (95% CI 17.2-40.1). At a median follow-up of 17.3 months, mPFS was 5.4 months (95% CI 3.6-6.8) and mOS was 8.7 months (95% CI 7.3-11.9). In the multivariate analysis, only ECOG-PS and BMI were confirmed independent predictors for shorter PFS [HR = 1.69 (95% CI 1.01-2.82), p = 0.04] [HR = 1.97 (95% CI 1.12-3.46), p = 0.01] and OS [HR = 1.69 (95% CI 1.01-2.83), p = 0.04] [HR = 2.08 (95% CI 1.17-3.70), p = 0.01]. CONCLUSION Efficacy of ramucirumab is confirmed in this "real-life" analysis. BWL seems not to have correlations with clinical outcomes in these patients, while BMI and ECOG-PS remain major prognostic factors. A possible explanation for the lack of prognostic effect of BWL might be the proportion of patients subjected to PTR in this series (52.5%).

Abstract
BACKGROUND Our aim was to determine factors predictive of long-term post-gastrectomy outcomes in older adults with pathological stage I gastric cancer (GC). METHODS A total of 175 patients with resected pathological stage I GC at two institutions were reviewed, each ≥75 years old at the time of gastrectomy and full participants in a 5-year follow-up program. The procedures were undertaken between January 2006 and December 2011. Patients were divided into two groups: survivors and non-survivors at postoperative Year 5. Univariate and multivariate analyses were applied to identify independent predictors of 5-years survival, including preoperative, surgical, and histopathologic variables. RESULTS Multivariate analysis of overall survival (OS) at 5 years indicated that prognostic nutritional index (PNI) <45 and the American Society of Anesthesiologists physical status (ASA-PS) 3 were independently associated with unfavorable outcomes. A clinical score consisting of 1-point each for these two variables proved useful in predicting survival after gastrectomy (5-year OS: 0 point, 86.6%; 1-point, 51.6%; 2-point, 33.3%; p < .001, area under the curve [AUC] = 0.757). CONCLUSIONS Long-term survival of older adults with pathological stage I GC is unfavorable in patients displaying both ASA-PS 3 and PNI < 45. A simple scoring method, based on combined ASA-PS/PNI determinations, provides an accurate prognostic prediction for these patients.

Abstract
The impact of BMI on survival in gastric cancer (GC) is not clear. We sought to explore the relationship between BMI and tumor site, clinicopathologic characteristics, postoperative complications, and prognosis in GC patients. Patients who underwent gastrectomy for GC between January 2011 and June 2016 formed the study cohort (n = 827). Patients were divided into three groups according to the BMI (in kg/m2): “low” (<18.5), “normal” (18.5–24.9), and “high” (≥25.0). The preoperative level of albumin and hemoglobin in the low BMI group was lower than that in the high BMI or normal BMI group ( P < 0.05). The prevalence of gastric-cardia cancer in the high BMI group was significantly higher than that in the low BMI group ( P = 0.001). The prevalence of gastric-antrum cancer in the high BMI group was significantly lower than that in the low BMI group ( P = 0.001) and the normal BMI group ( P = 0.004). The BMI of patients with gastric-cardia cancer was significantly higher than that of patients with gastric-body cancer ( P = 0.018) and gastric-antrum cancer ( P < 0.001). There were no significant differences among the three groups in terms of tumor size, TNM stage, depth of tumor invasion, degree of tumor differentiation, resection margin, lymph node metastasis, or postoperative complications. BMI was not an independent factor that influenced the prognosis. We found a relationship between BMI and GC site. A low BMI may be associated with a poor prognosis and a high BMI may be related to a favorable prognosis. BMI was not an independent factor that influenced GC prognosis.

Abstract
BACKGROUND The effects of obesity on prognosis in gastric cancer are controversial. AIMS To evaluate the association between body mass index (BMI) and mortality in patients with gastric cancer. METHODS A single-institution cohort of 7765 patients with gastric cancer undergoing curative gastrectomy between October 2000 and June 2016 was categorized into six groups based on BMI: underweight (< 18.5 kg/m2), normal (18.5 to < 23 kg/m2), overweight (23 to < 25 kg/m2), mildly obese (25 to < 28 kg/m2), moderately obese (28 to < 30 kg/m2), and severely obese (≥ 30 kg/m2). Hazard ratios (HRs) for overall survival (OS) and disease-specific survival (DSS) were calculated using Cox proportional hazard models. RESULTS We identified 1279 (16.5%) all-cause and 763 (9.8%) disease-specific deaths among 7765 patients over 83.05 months (range 1.02-186.97) median follow-up. In multivariable analyses adjusted for statistically significant clinicopathological characteristics, preoperative BMI was associated with OS in a non-linear pattern. Compared with normal-weight patients, underweight patients had worse OS [HR 1.42; 95% confidence interval (CI) 1.15-1.77], whereas overweight (HR 0.84; 95% CI 0.73-0.97), mildly obese (HR 0.77; 95% CI 0.66-0.90), and moderately obese (HR 0.77; 95% CI 0.59-1.01) patients had better OS. DSS exhibited a similar pattern, with lowest mortality in moderately obese patients (HR 0.58; 95% CI 0.39-0.85). Spline analysis showed the lowest all-cause mortality risk at a BMI of 26.67 kg/m2. CONCLUSION In patients undergoing curative gastric cancer surgery, those who were overweight or mildly-to-moderately obese (BMI 23 to < 30 kg/m2) preoperatively had better OS and DSS than normal-weight patients.

Does high body mass index negatively affect the surgical outcome and long-term survival of gastric cancer patients who underwent gastrectomy: A systematic review and meta-analysis. Eur J Surg Oncol 2018; 44:1971-1981. [PMID: 30348605 DOI: 10.1016/j.ejso.2018.09.007] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2018] [Revised: 09/05/2018] [Accepted: 09/16/2018] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Whether high body mass index (BMI) was associated with increased postoperative complications and unfavorable prognosis of gastric cancer (GC) patients remain controversial. In the present study, we performed a systematic review and meta-analysis to evaluate the impact of high BMI on surgical outcome, postoperative complications and long-term survival of GC patients. METHODS The related studies were identified by searching PubMed and Embase databases. According to the BMI, all GC patients were classified into BMI ≥25 kg/m2 group and BMI <25 kg/m2 group. The relevant data was extracted and pooled effect size was assessed using a fixed effect model or random effect model. RESULTS A total of 36 relevant studies involving 30,642 GC patients were included in this meta-analysis. The results indicated that high BMI patients had longer operation time, fewer number of retrieved lymph nodes and larger amount of intraoperative blood loss than other patients, regardless of open gastrectomy or laparoscopic gastrectomy. In addition, the risk of postoperative complications was significantly higher in the patients with BMI ≥25 kg/m2 than in those with BMI <25 kg/m2, especially for infectious complications. However, high BMI had no negative impact on postoperative mortality and long-term survival of GC patients. CONCLUSION Despite the increased surgical difficulty and postoperative complications, high BMI was not associated with the prognosis of GC patients. To reduce the risk of postoperative complications, more meticulous operation technique and improved perioperative management should be necessary for high BMI patients.

Abstract
PURPOSE The aim of this study was to investigate the impact of preoperative low body mass index (BMI) on both the short- and long-term outcomes in patients with gastric cancer. MATERIALS AND METHODS A total of 510 patients with gastric cancer were divided into the following 3 groups: low BMI group (≤18.5 kg/m2, n=51), normal BMI group (18.6-24.9 kg/m2, n=308), and high BMI group (≥25.0 kg/m2, n=151). RESULTS There were significantly more stage III/IV patients in the low BMI group than in the other groups (P=0.001). Severe postoperative complications were more frequent (P=0.010) and the survival was worse (P<0.001) in the low BMI group. The subgroup analysis indicated that survival was worse in the low BMI group of the stage I/II subgroup (P=0.008). The severe postoperative complication rate was higher in the low BMI group of the stage III/IV subgroup (P=0.001), although the recurrence rate and survival did not differ in the stage III/IV subgroup among all the BMI groups. Low BMI was an independent poor prognostic factor in the stage I/II subgroup (disease-free survival: hazard ratio [HR], 13.521; 95% confidence interval [CI], 1.186-154.197; P=0.036 and overall survival: HR, 5.130; 95% CI, 1.644-16.010; P=0.005), whereas low BMI was an independent risk factor for severe postoperative complications in the stage III/IV subgroup (HR, 17.158; 95% CI, 1.383-212.940; P=0.027). CONCLUSIONS Preoperative low BMI in patients with gastric cancer adversely affects survival among those with stage I/II disease and increases the severe postoperative complication rate among those with stage III/IV disease.

Abstract
Background: Most patients with gastric cancer rapidly lose weight after gastrectomy. Therefore, analysis of the effect of body mass index (BMI) on patients with gastric cancer survival should include postoperative BMI and BMI loss and preoperative BMI. This retrospective cohort study analyzed the effect of three BMI variables and their interaction on long-term outcomes.Methods: Preoperative BMI analysis included 2,063 patients with gastric cancer who underwent curative gastrectomy between January 2009 and December 2013 at Seoul National University Bundang Hospital. BMI at postoperative 6 to 12 months was available in 1,845 of these cases.Results: Patients with preoperative BMI 23.0 to <27.5 [HR, 0.63; 95% confidence interval (CI), 0.48-0.82 for BMI 23.0 to <25.0 and HR, 0.57; 95% CI, 0.42-0.78 for BMI 25.0 to <27.5] and postoperative BMI 23.0 to <25.0 (HR, 0.67; 95% CI, 0.46-0.98) showed significantly better overall survival (OS) than pre- and postoperative patients with BMI 18.5 to <23.0, respectively. Postoperative underweight (BMI <18.5; HR, 1.74; 95% CI, 1.27-2.37) and postoperative severe BMI loss (>4.5; HR, 1.79; 95% CI, 1.29-2.50) were associated with higher mortality. Severe BMI loss and preoperative BMI <23.0 had an adverse synergistic effect; patients with BMI <23.0 were more vulnerable to severe BMI loss than those with BMI ≥23.0. Associations with cancer-specific survival were similar.Conclusions: All three BMI variables were prognostic factors for survival of patients with gastric cancer. Preoperative BMI and severe BMI loss had an interaction.Impact: Perioperative BMI and weight loss should be analyzed collectively in patients with gastric cancer undergoing gastrectomy.

Abstract
BACKGROUND Increasing numbers of studies have shown that postoperative complication is a negative predictor of long-term survival outcomes in various malignancies. However, the impact of severity of complications on long-term survival for patients with gastric cancer still remains unclear. This study aimed to explore the relationship between the severity of complications and long-term survival outcomes after laparoscopic total gastrectomy (LTG) for advanced gastric cancer (AGC). METHODS The study analyzed 571 patients with AGC who underwent LTG in a single institution between April 2008 and June 2015. Patients were divided into two groups based on the occurrence or absence of postoperative complications which were recorded using the Clavien-Dindo (C-D) classification. Long-term survival outcomes were compared between groups in the propensity score-matched cohort. RESULTS The groups were well balanced after the propensity score matched. The complication (C) group was associated with decreased 5-year cancer-specific survival (CSS) (65.1% vs. 76.2%, P=0.049). Subgroup analysis showed that the severe complication (C-D grade > II) group was associated with decreased 5-year overall survival (OS) (46.3% vs. 65.9%, P = 0.042) and cancer-specific survival (CSS) (53.7% vs. 74.4%, P = 0.030). However, a comparative analysis of 5-year OS and CCS showed no significant differences between the minor complication (C-D grade II) group and matched NC group (68.9% vs. 72.2%, P = 0.578; 75.6% vs. 77.8%, P = 0.649; respectively). Multivariate analysis confirmed severe complication was an independent risk factor for decreased OS. Further analysis showed that older age, lower body mass index (BMI), and combined resection were independent risk factor for the occurrence of severe complications. CONCLUSIONS Severe complications adversely affected long-term survival outcomes after LTG with D2 lymph node dissection for AGC. More attention should be paid to patients at high risk for severe complications in preoperative assessment and postoperative management.

Abstract
Background The association between body mass index (BMI) and clinical outcomes of gastric cancer were still under debate. The aim of the present study was to investigate the impact of BMI on intraoperative conditions, postoperative complications and prognosis of gastric cancer. Methods From October 2008 to March 2015, 1210 gastric cancer patients treated with D2 gastrectomy were enrolled in the present study. Patients were divided into three groups: low BMI group (BMI < 18.5 Kg/m2), normal BMI group (18.5 Kg/m2 ≤ BMI < 25.0 Kg/m2) and high BMI group (BMI ≥ 25.0 Kg/m2). Clinicopathological characteristics and prognosis of patients were recorded and analyzed. Propensity score matching was used to match patients in the three groups. Results There were 107 patients in low BMI group (8.9%), 862 patients in normal BMI group (71.2%) and 241 patients in high BMI group (19.95%). Before matching, BMI was inversely associated with tumor size, tumor depth, lymph node metastasis (LNM) and tumor stage (all P < 0.05). After matching, the clinicopathological features were all comparable among the three groups (all P > 0.05). High BMI was associated with increased blood loss and operation time, and deceased number of retrieved lymph nodes (all P < 0.05). For postoperative complications, low BMI was associated with decreased rate of postoperative fever (P = 0.025). Age, BMI, tumor size, Borrmann type, pathological type, type of gastrectomy, tumor depth, LNM and tumor stage were risk factors for the prognosis of gastric cancer. Multivariate analysis showed that only BMI, tumor size, tumor depth and LNM were independent prognostic factors. The overall survival of patients with low BMI was significantly worse than patients with normal (P < 0.05) or high BMI (P < 0.05). However, the overall survival was comparable between patients with normal and high BMI (P > 0.05). Conclusions BMI was inversely associated with tumor size, tumor depth, LNM and tumor stage. High BMI was associated with increased blood loss and operation time, and deceased number of retrieved lymph nodes. Low BMI was associated with decreased rate of postoperative fever and decreased survival.

Abstract
Malnutrition is a common finding in cancer patients, which can affect disease progression and survival. This review aims to critically summarize the prognostic role of nutritional status, from Body Mass Index (BMI) and weight loss to nutrition screening tools and biochemical indices, in cancer patients. According to the currently available data, Prognostic Nutritional Index (PNI) was a significant prognostic factor of patients' survival, both in univariate and multivariate analyses. Pre-operative albumin was also correlated with worse outcomes, being an independent prognostic factor of survival in several studies. BMI was also well-studied, with contradictory results. Although, lower BMI was found to be an independent prognostic factor of shorter survival in some studies, in others it did not have an impact on survival. In this aspect, this review highlights the significant prognostic role of nutritional status in the disease progression and survival of cancer patients. Further, good-quality prospective studies are needed in order to draw precise conclusions on the prognostic role of specific nutritional assessment tools, and biochemical indices associated with the nutritional status in more cancer types, such as liver, breast and prostate cancer, and hematological malignancies.

Abstract
Malnutrition is very common in gastric cancer patients and can be detected in up to 85% of patients with gastric cancer. Malnutrition is associated with increased morbidity and mortality, prolonged hospital stay, poor treatment tolerance, and lower survival rate. Malnutrition also has an impact on quality of life. The early detection of nutritional risk with appropriate nutritional care can significantly reduce patient's postoperative morbidity and mortality. Because there is no gold standard tool, appropriate tools should be selected and applied depending on one's institutional conditions. And, it is recommended that nutritional assessment should be achieved for every patient at pre/post-operative period.

Abstract
ABSTRACT Objectives: to determine the nutritional evaluation method that best predicts mortality in 90 days of patients submitted to gastrectomy for gastric cancer. Methods: we conducted a prospective study with 44 patients with gastric cancer, stages II to IIIa, of whom nine were submitted to partial gastrectomy, 34 to total gastrectomy, and one to esophago-gastrectomy. All patients were nutritionally evaluated through the same protocol, up to 72h after hospital admission. The parameters used were Patient-Generated Subjective Global Assessment (PGSGA), classical anthropometry, current weight and height, percentage of weight loss (%WL) and body mass index (BMI). We also measured the thickness of the thumb adductor muscle (TAM) in both hands, dominant hand (TAMD) and non-dominant hand (TAMND), as well as the calculated the prognostic nutritional index (PNI). The laboratory profile included serum levels of albumin, erythrocytes, hemoglobin, hematocrit, leukocytes, and total lymphocytes count (TLC). Results: of the 44 patients studied, 29 (66%) were malnourished by the subjective method, 15 being grade A, 18 grade B and 11 grade C. Cases with PGSGA grade B and TAMD 10.2±2.9 mm were significantly associated with higher mortality. The ROC curves (95% confidence interval) of both PGSGA and TAMD thickness reliably predicted mortality at 30 and 90 days. No laboratory method allowed predicting mortality at 90 days. Conclusion: PGSGA and the TAMD thickness can be used as preoperative parameters for risk of death in patients undergoing gastrectomy for gastric cancer.

Positive Effect of Higher Adult Body Mass Index on Overall Survival of Digestive System Cancers Except Pancreatic Cancer: A Systematic Review and Meta-Analysis. BIOMED RESEARCH INTERNATIONAL 2017; 2017:1049602. [PMID: 28948163 PMCID: PMC5602622 DOI: 10.1155/2017/1049602] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/24/2017] [Revised: 05/27/2017] [Accepted: 05/31/2017] [Indexed: 02/08/2023]
Abstract
High body mass index (BMI) has been inconsistently associated with overall survival (OS) of digestive system cancers (DSCs). This meta-analysis was conducted to investigate whether high BMI was associated with DSCs prognosis. 34 studies were accepted, with a total of 23,946 DSC cases. Hazard ratios (HRs) with 95% confidence intervals (95% CIs) for OS in BMI categories from individual studies were extracted and pooled by random-effect model. The overall HR of DSCs except pancreatic cancer for OS of adult overweight cases was 0.76 (95% CI = 0.67–0.85). DSC individuals except pancreatic cancer with adult obesity were at decreased risk for OS (HR = 0.85, 95% CI = 0.72–0.98). Among DSC patients except pancreatic cancer, the overall HR for the highest versus the lowest BMI category was 0.82 (95% CI = 0.71–0.92). Additionally, comparing the highest and lowest BMI categories, the combined HR of pancreatic cancer was 1.22 (95% CI = 1.01–1.43). Our meta-analysis suggested an increased OS among adult overweight and obese DSC survivors except pancreatic cancer. Overweight and obesity in adulthood may be important prognostic factors that indicate an increased survival from DSC patients except pancreatic cancer.

Abstract
BACKGROUND Malnutrition and immunological status are associated with survival in many cancers. Prognostic nutritional index (PNI) and body mass index (BMI) are recognized immune-nutritional indices and associated with postoperative outcome in hepatocellular carcinoma (HCC) patients. However, this association is still controversial. Our aim was to determine whether the combination of PNI and BMI is better than either alone in HCC patients' prognosis. MATERIAL AND METHODS Preoperative PNI and BMI, patient demographics, clinical and pathological data from 322 HCC patients were collected and analyzed. RESULTS Low PNI was correlated with age, cirrhosis, total bilirubin (TBIL) ≥34.2 μmol/L, and recurrence. Likewise, low BMI was associated with TBIL ≥34.2 μmol/L, portal vein tumor thrombi (PVTT), tumor size, tumor differentiation, TNM stage, and recurrence. Multivariate analysis identified TNM stage, PVTT, tumor size, PNI, and BMI as independent predictors of outcome in HCC patients. Low PNI combined with BMI (PNI + BMI) accurately predicted poorer outcome, particularly in patients with TNM stage I HCC. The predictive range of PNI + BMI was more sensitive than that of either alone. CONCLUSIONS preoperative PNI/BMI is an independent predictor of outcome for HCC patients, especially in patients with early stage HCC. Intriguingly, the PNI + BMI combination can enhance the accuracy of prognosis.

Abstract
Objective To prospectively investigate associations of presurgical body mass index (BMI) with clinicopathological factors and its prognostic significance in radically D2-resected patients with non-metastasized gastric cancer (GC) and Siewert type II/III adenocarcinoma of esophagogastric junction (AEG). Methods A large prospective cohort consisting of radically-resected GC and AEG patients was analyzed. Follow-up was successful in 671 out of 700 patients, who were categorized into underweight (BMI<18.5), normal-weight (BMI=18.5-22.9), overweight (BMI=23-24.9), and obese (BMI≥25) groups according to Asian standards. BMI-associated factors were explored using multivariable logistic regression with adjustment. Cancer-specific survival analyses were conducted applying both univariable and multivariable Cox regression methods. Results Pre-operation, higher hemoglobin levels and smaller anemia proportions were observed in larger BMI groups. Higher BMI tended to be associated with higher neutrophil-lymphocyte ratios (NLRs). Patients with higher BMI had smaller tumors and more often stage I tumors, but longer surgical time and postsurgical stay. In multivariable analyses, higher hemoglobin levels, upper tumor location, poorer differentiation, and higher NLR were significantly associated with higher BMI. Overall, survival analyses revealed no significant role of BMI. However, in further stratifications after adjustment, compared to patients with normal BMI, obese patients had better survival in women, but worse in those with AEG; underweight was associated with reduced mortality risk in tumors differentiated well to moderately; overweight patients had increased death hazard when having thrombocytopenia. Conclusion Overall, preoperative BMI had limited prognostic significance in operated GC patients. However, under specific conditions (e.g., female, AEG, good differentiation, and thrombocytopenia), BMI might indicate postoperative survival.

Abstract
Importance Elevated body mass index (BMI) has been proposed as a risk factor for morbidity and mortality among patients undergoing surgery. Conversely, an elevated BMI may confer a protective effect on perioperative morbidity. Objective To examine whether an elevated BMI is an independent risk factor for perioperative and postoperative infectious complications after free tissue transfer in head and neck reconstructive surgery. Design, Setting, and Participants This cohort study included patients undergoing major head and neck surgery requiring free tissue transfer at a tertiary care center. Data were collected for 415 patients treated from January 1, 2007, through December 31, 2014. Main Outcomes and Measures The outcome of interest was postoperative infection and complications after head and neck surgery using free flaps. Covariates considered for adjustment in the statistical model included alcohol consumption (defined as >5 drinks per day [eg, 360 mL of beer, 150 mL of wine, or 45 mL of 80-proof spirits]), type 2 diabetes, prior radiotherapy, anesthesia time, hypothyroidism, smoking, American Society of Anesthesiologists classification, antibiotic regimen received (defined as a standard regimen of a first- or second-generation cephalosporin with or without metronidazole hydrochloride vs an alternative antibiotic regimen for patients allergic to penicillin), and primary surgeon. A multiple logistic regression model was developed for the incidence of the infection end point as a function of elevated BMI (>30.0). Results Among the 415 patients included in this study (277 men [66.7%] and 138 women [33.2%]; mean [SD] age, 61.5 [13.9] years), type 2 diabetes and use of an alternative antibiotic regimen were found to be independently associated with increased infectious complications after free flap surgery of the head and neck, with estimated odds ratios of 2.78 (95% CI, 1.27-6.09) and 2.67 (95% CI, 1.14-6.25), respectively, in the multiple logistic regression model. However, a high BMI was not found to be statistically significant as an independent risk factor for postoperative infectious complication (estimated odds ratio, 1.19; 95% CI, 0.48-2.92). Conclusions and Relevance Elevated BMI does not seem to play a role as an independent risk factor in postoperative complications in free tissue transfer in head and neck surgery.

Abstract
Postgastrectomy syndromes result from altered form and function of the stomach. Gastrectomy disrupts reservoir capacity, mechanical digestion and gastric emptying. Early recognition of symptoms with prompt evaluation and treatment is essential. Many syndromes resolve with minimal intervention or dietary modifications. Re-operation is not common but often warranted for afferent and efferent loop syndromes and bile reflux gastritis. Preoperative nutritional assessment and treatment of common vitamin and mineral deficiencies after gastrectomy can reduce the incidence of chronic complications. An integrated team approach to risk assessment, patient education, and postoperative management is critical to optimal care of patients with gastric cancer.

Abstract
Background The aim of this study is to investigate whether body mass index (BMI) is a prognostic factor in gastric cancer patients with peritoneal dissemination. Methods This is a retrospective study consisting of 518 patients with a histological diagnosis of gastric cancer with peritoneal dissemination seen at the Sixth Affiliated Hospital of Sun Yat-Sen University and Sun Yat-sen University Cancer Center between January 2010 and April 2014. Patients were followed until December 2015. Chi-square test and Kaplan-Meier survival analysis were used to compare the clinicopathological variables and prognosis. Results Univariate analyses showed that significant prognostic factors included palliative gastrectomy (p < 0.001), tumor size (p < 0.001), tumor location (p = 0.011), peritoneal seeding grade (p < 0.001), ascites (p = 0.001), serum CEA level (p = 0.002), serum CA19-9 level (p = 0.033), palliative chemotherapy (p < 0.001), and BMI group (p < 0.001). For patients with palliative chemotherapy, univariate analysis revealed that palliative gastrectomy (p < 0.001), tumor size (p = 0.002), tumor location (p = 0.024), peritoneal seeding grade (p = 0.008), serum CEA level (p = 0.041), and BMI group (p < 0.001). Multivariate analysis revealed that BMI was an independent prognostic factor in gastric cancer patients with peritoneal dissemination, especially in patients who received palliative chemotherapy. Conclusions BMI is a prognostic factor for patients who have gastric cancer with peritoneal dissemination, especially in those who received palliative chemotherapy.

Abstract
PURPOSE This study was performed to determine the association of frailty and nutritional status with postoperative complications after total gastrectomy (TG) with D2 lymphadenectomy in patients with gastric cancer. METHODS Patients undergoing TG with D2 lymphadenectomy for gastric cancer between August 2014 and February 2016 were enrolled. Frailty was evaluated by sarcopenia which was diagnosed by a combination of third lumbar vertebra muscle index (L3 MI), handgrip strength, and 6-m usual gait speed. Nutritional status was evaluated by the nutritional risk screening 2002 (NRS 2002) score. Univariate and multivariate analyses evaluating the risk factors for postoperative complications were performed. RESULTS A total of 158 patients were analyzed, and 27.2 % developed complications within 30 days of surgery. One patient died within 30 days of the operation. In the univariate analyses, NRS 2002 score ≥3 (OR = 2.468, P = 0.012), sarcopenia (OR = 2.764, P = 0.008), and tumor located at the cardia (OR = 2.072, P = 0.046) were associated with the postoperative complications. Multivariable analysis revealed that sarcopenia (OR = 3.084, P = 0.005) and tumor located at the cardia (OR = 2.347, P = 0.026) were independent predictors of postoperative complications. CONCLUSIONS This study showed a significant relationship between postoperative complications and geriatric frailty using sarcopenia in patients with gastric cancer after TG with D2 lymphadenectomy. Frailty should be integrated into preoperative risk assessment and may have implications in preoperative decisionmaking.

Abstract
This study evaluated the effect of an immune-modulatory diet on patients with gastric cancer and identified the parameters associated with postoperative outcomes. This was a single-arm prospective intervention study. At baseline, patients were assessed for nutrition (Patient-Generated Subjective Global Assessment), inflammatory markers (albumin, C-reactive protein, and interleukin 6 [IL-6]), and immune markers (percentage NK, CD4, CD8, and CD4:CD8 ratio); they also received nutrition counseling and high-calorie/protein supplement. A week before surgery, they were assessed for nutrition and inflammatory/immune markers and started on an immune-modulatory supplement until the day before surgery, when they were evaluated again. On the second postoperative day, patients were assessed for inflammatory/immune parameters, and a final nutrition evaluation was performed until the day of discharge. Complications were recorded daily and up to 30 days after discharge. Thirty-seven patients (60 ± 10 years old) were included, and 57% were classified as malnourished. Maintenance of nutrition and immune parameters occurred throughout the study period, but we found a preoperative increase in C-reactive protein (0.1-1.5 mg/dL) and IL-6 (2.0-14.2 pg/mL) and a postoperative increase in the CD4:CD8 ratio (2.3 ± 1.0). Complications and death were seen in 35%, especially patients with higher preoperative IL-6 (2.2-46 pg/mL), lower CD4:CD8 ratio (1.7 ± 0.5), and lower protein (1.2 ± 0.5 g/kg/d) and calorie intake (1552 ± 584 kcal/kg/d). The high-calorie/protein supplementation with the immune-modulating diet was able to maintain the nutrition and immune status of patients with gastric cancer.

Abstract
BACKGROUND In humans and rodents obesity appears to promote some cancers by increasing incidence, tumor aggressiveness, recurrence, and fatality. However, the relationship between obesity and cancer in dogs has not been thoroughly evaluated. HYPOTHESIS/OBJECTIVES Whether body condition score (BCS) at the time of lymphoma (LSA) or osteosarcoma (OSA) diagnosis in dogs is predictive of survival time (ST) or progression-free interval (PFI). We hypothesized that an overweight body state at the time of cancer diagnosis would be associated with negative outcomes. ANIMALS Dogs with LSA (n = 270) and OSA (n = 54) diagnosed and treated between 2000 and 2010. METHODS Retrospective case review. Signalment, body weight, BCS, cancer diagnosis and treatment, relevant clinicopathologic values, and survival data were collected. Dogs were grouped by BCS (underweight, ideal, and overweight) and ST and PFI were compared. RESULTS Overall, 5.5% of dogs were underweight, 54.0% were ideal weight, and 40.4% were overweight at diagnosis. Underweight dogs with LSA had shorter ST (P = .017) than ideal or overweight dogs. BCS was not associated with ST for OSA (P = .474). Progression-free interval did not differ among BCS categories for either cancer. CONCLUSIONS AND CLINICAL IMPORTANCE Obesity was not associated with adverse outcomes among dogs with LSA or OSA in this retrospective study; however, being underweight at the time of diagnosis of LSA was associated with shorter survival. More research is needed to elucidate the relationship between excessive body weight and cancer development and progression in dogs.

Comparison of Survival Rates, Tumor Stages, and Localization in between Obese and Nonobese Patients with Gastric Cancer. Gastroenterol Res Pract 2016; 2016:9382750. [PMID: 27418926 PMCID: PMC4932154 DOI: 10.1155/2016/9382750] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2016] [Revised: 04/27/2016] [Accepted: 05/25/2016] [Indexed: 12/17/2022] Open
Abstract
Purpose. In this study we tried to determine the association between body-mass index (BMI), survival rate, and the stage of tumor at the time of diagnosis in patients with gastric cancer. Methods. A total of 270 gastric cancer patients' hospital records were retrospectively evaluated. Patients were grouped according to their BMI at the time of tumor diagnosis. Tumor stages at admission were compared according to their BMI values. Results. There were no differences in OS among BMI subgroups (p = 0.230). The percent of patients with stage III tumor was significantly higher in nonobese while the percent of stage IV tumor was surprisingly higher in obese patients (p was 0.011 and 0.004, resp.). Percent of patients who did not have any surgical intervention was significantly lower in overweight and obese patients than normal and/or underweight patients. Conclusions. At the time of diagnosis, obese patients had significantly higher percent of stage IV tumor than nonobese patients. Despite of that, there were no differences in survival rates among BMI subgroups. Our study results are consistent with "obesity paradox" in gastric cancer patients. We also did not find any relationship between BMI and localization of gastric tumor.
