RESUMEN
BACKGROUND: Weight loss (WL) after gastrectomy for gastric cancer is associated with both decreased compliance with adjuvant chemotherapy and impaired survival. This study examined the effects of administering oral nutritional supplements (ONS) for 3 months after gastrectomy in terms of compliance with adjuvant chemotherapy and survival outcomes. METHODS: This large-scale, multicenter, open-label, randomized controlled trial enrolled 1,003 gastric cancer patients undergoing curative gastrectomy. Patients were assigned to the control group (n = 503) or ONS group (n = 500). In the ONS group, 400 kcal/day of ONS was recommended in addition to a regular diet for 3 months after gastrectomy. Compliance with adjuvant chemotherapy and survival outcomes were compared between the two groups. RESULTS: Compared with the control group, the ONS group showed significantly decreased WL at 3 months after gastrectomy (8.6 ± 6.1 vs. 7.2 ± 5.7%, respectively, P = 0.0004). The control and ONS groups did not differ regarding the induction rate of adjuvant chemotherapy (84.9 vs. 82.8%, respectively, P = 0.614) or the continuation rate at 3 months postoperatively (75.3 vs. 76.6%, respectively, P = 0.809). Oral nutritional supplements for 3 months showed no survival benefit; the 3- and 5-year overall survival (OS) rates were 91.3% and 87.6% in the control group and 89.6% and 86.4% in the ONS group, respectively, indicating no significant difference (P = 0.548). Subgroup analysis could not detect a population in which ONS administration increased OS. CONCLUSIONS: Administration of ONS for 3 months after gastrectomy was not associated with increased compliance with adjuvant chemotherapy or with improved prognosis.
RESUMEN
INTRODUCTION: Healthy eating and weight control are recommended for cancer survivors; however, dietary interventions are not routinely offered to them. This study aimed to assess the effects of dietary interventions on survival, nutritional status, morbidity, dietary changes, health-related quality of life (QOL), and clinical measures in cancer survivors. METHODS: Searches were conducted from October 1, 2018 to November 21, 2011 in the Medline, EMBASE, CENTRAL, Emcare, and DARE electronic databases. We included randomized controlled trials (RCTs) that involved individuals diagnosed with cancer, excluding conference abstracts, case studies, other reviews, and meta-analyses, and screened the articles. RESULTS: Eight studies were included in this meta-analysis. We observed significant improvements in QOL and clinical data in 3 of 6 studies and in one study, respectively, significant weight loss on anthropometry in 2 of 5 studies, and dietary improvement in 4 of 5 studies of adult cancer survivors. However, we did not observe any benefits of dietary intervention for cancer survivors with undernutrition. DISCUSSION: Dietary interventions for adult cancer survivors might contribute to improving their nutritional status; however, further clarification requires a study that standardizes the intervention method. Furthermore, RCTs are required to determine the effects on cancer survivors with undernutrition.

BACKGROUND: APC and MUTYH are both well-known colorectal polyposis causative genes. However, 30-50% of colorectal adenomatous polyposis cases are classified as colonic adenomatous polyposis of unknown etiology and lack identifiable pathogenic variants. Although guidelines recommend total proctocolectomy for colonic adenomatous polyposis of unknown etiology with over 100 adenomas, evidence is lacking. This study presents a unique case of localized colonic adenomatous polyposis of unknown etiology with multiple adenocarcinomas, treated with hemicolectomy and regional lymph node dissection. CASE PRESENTATION: The patient was a 72-year-old woman whose colonoscopy revealed numerous polyps and two adenocarcinomas localized in the right side of the colon, with no lesions in the left side. The patient had no family history of polyposis or colorectal cancer. No extracolonic lesions, enlarged lymph nodes, or distant metastases were found. Considering the patient's age and lesion localization, laparoscopic right hemicolectomy with regional lymph node dissection was performed. Histopathological diagnosis revealed three adenocarcinoma lesions with no lymph node metastasis. The most advanced pathological stage was T2N0M0 Stage I (UICC 8th edition). The patient was alive 5 years postoperatively, without recurrence of cancer or polyposis in the remaining colon and rectum. To diagnose hereditary colorectal cancer/polyposis, a germline multigene panel testing for APC, EPCAM, MBD4, MLH1, MLH3, MSH2, MSH3, MSH6, MUTYH, NTHL1, PMS2, POLD1, POLE, and TP53 was performed using DNA extracted from blood samples: however, no pathogenic variant was detected. Therefore, the patient was diagnosed with colonic adenomatous polyposis of unknown etiology. CONCLUSIONS: In this rare case, colonic adenomatous polyposis of unknown etiology, with numerous adenomatous polyps and multiple adenocarcinomas localized in the right side of the colon, was successfully treated with right hemicolectomy and regional lymph node dissection. Despite genetic analysis, no causative germline variants were identified. Segmental colectomy according to the distribution of polyps might be a curative approach.
RESUMEN
BACKGROUND: Cardiac tamponade is a rare postoperative complication of esophageal cancer surgery, which leads to rapid hemodynamic changes and can be fatal if not treated properly and promptly. Herein, we report a case of cardiac tamponade after thoracoscopic subtotal esophagectomy and retrosternal gastric tube reconstitution for esophageal cancer that was successfully treated with surgical drainage. CASE PRESENTATION: An 86-year-old man with lower thoracic esophageal cancer underwent thoracoscopic subtotal esophagectomy and retrosternal gastric tube reconstitution. No intra-operative complications were observed. On the first postoperative day, tachycardia and hypotension were observed, and pericardial effusion was identified on computed tomography images. The patient was diagnosed with obstructive shock secondary to cardiac tamponade. As percutaneous puncture drainage was not possible due to the presence of a retrosternal gastric tube, pericardiotomy with a small left anterior thoracotomy was performed, and a large amount of hematogenous fluid was drained, which instantly improved circulation. On the second postoperative day, the patient showed decreased pulse pressure, and computed tomography revealed a residual and enlarged hematoma around the right ventricle. The patient underwent surgical drainage and another pericardiotomy with a small right anterior thoracotomy was performed to drain the hematoma. At this time, multiple injuries to the fatty tissue, epicardium, and myocardium with active bleeding were observed on the anterior surface of the right ventricle near the root of the pulmonary artery. In this patient, the ascending aorta ran further to the right and dorsal sides than usual, causing the anterior wall of the right ventricle near the root of the pulmonary artery to be closer to the back of the sternum. This abnormality may have contributed to injury during the creation of the retrosternal pathway, leading to cardiac tamponade. CONCLUSIONS: Cardiac tamponade after esophagectomy can occur because of manipulation during creation of the retrosternal route, with an anomaly in the aortic position being present in this case. Gentle manipulation and selection of the reconstruction route according to the patient's condition are necessary in cases with such anatomical abnormalities.
RESUMEN
BACKGROUND: Multidisciplinary treatment combining chemotherapy, chemo radiation therapy (CRT), and surgery has been utilized for advanced esophageal cancer. However, preoperative treatment could cause postoperative inflammation and complications. We hypothesized that fibrosis surrounding tumor tissue caused by preoperative treatment could induce postoperative systemic inflammation and influence postoperative complications. METHODS: Surgical specimens from patients with thoracic esophageal cancer who underwent preoperative CRT (38 cases) or chemotherapy (77 cases) and those who received no preoperative treatment (49 cases) were evaluated to measure the fibrotic area adjacent to the tumor (10 mm from the tumor edge) by applying Azan staining. Pleural effusion and peripheral blood serum interleukin-6 levels were analyzed to evaluate local and systemic postoperative inflammation in 37 patients. RESULTS: The fibrotic areas around the tumors were significantly larger in patients who underwent preoperative CRT than in patients who underwent chemotherapy (p < 0.001) or who had received no preoperative therapy (p < 0.001). Infectious complications were higher in patients who underwent preoperative CRT than chemotherapy (p = 0.047) or surgery alone (p < 0.001). The patients with larger fibrotic areas had more infectious complications (p = 0.028). Multivariate analysis showed that both a large fibrotic area and preoperative CRT were correlated with infectious complications, but not significantly. Pleural effusion interleukin-6 was significantly higher in patients who underwent preoperative CRT than in patients who received no preoperative therapy (p = 0.013). CONCLUSIONS: A large fibrotic peritumoral esophageal tissue area after preoperative treatment could cause postoperative inflammatory response and infectious complications.

Aim: To compare the effects of open (OG) and laparoscopic gastrectomy (LG) on body composition and muscle strength. Methods: This study performed a propensity score matching analysis using cases from a large-scale, multicenter, phase III randomized controlled trial concerning oral nutritional supplements after gastrectomy and analyzed both the whole and matched cohorts. Measurements of body composition and hand grip strength (HGS) were performed at baseline (preoperatively) and at 1, 2, 3, 6, and 12 months after gastrectomy. Results: Of 835 patients, 275 and 560 underwent OG and LG, respectively. Skeletal muscle mass (SMM) and HGS loss were significantly lesser in the LG group than in the OG group. The propensity score-matched analysis, including 120 pairs of patients, confirmed that the % SMM loss values at 1, 2, 3, 6, and 12 POM were -4.5%, -4.0%, -4.7%, -4.6%, and -5.8% in the OG group and -3.0%, -1.9%, -2.4%, -2.2%, and -2.7% in the LG group, respectively. The % SMM loss was significantly lesser in the LG group than in the OG group (repeated measures ANOVA p < 0.001). The HGS loss was non-significantly smaller in the LG group than in the OG group. Conclusion: Skeletal muscle mass loss was significantly lesser in the LG group than in the OG group in both cohorts, indicating that LG may be more effective than OG for maintaining muscle mass.
RESUMEN
PURPOSE: To investigate the association between perioperative deglutition screening and postoperative respiratory complications (PRCs) in elderly patients undergoing gastrectomy for gastric cancer. METHODS: We analyzed data from 86 patients with gastric cancer (aged ≥ 70 years) who underwent gastrectomy between October, 2016 and November, 2018. Videofluoroscopic swallowing examinations (VFSEs) were performed before and after surgery. We examined the association of these results with postoperative respiratory complications, as well as the relationships between demographic, operative, and swallowing function assessment data. RESULTS: PRCs were identified in 16 patients. The results of pre- and postoperative VFSE showed abnormalities in 28 and 32 patients, respectively. Multivariate analysis revealed that abnormalities in the postoperative VFSEs were strongly associated with the development of PRCs (P = 0.002). The findings of this analysis suggests that ventilatory impairment, a Charlson comorbidity index score ≥ 3, and an open surgical approach are independent risk factors for PRCs. CONCLUSION: This is the first study to demonstrate the efficacy of perioperative assessment of swallowing function using VFSE for predicting PRCs in elderly patients undergoing gastrectomy for gastric cancer.

BACKGROUND: In the short term, pylorus-preserving gastrectomy (PPG) has been reported to have advantages over distal gastrectomy (DG) with regard to postprandial symptoms and dumping syndrome. We aimed to evaluate the quality of life after PPG for early gastric cancer in the long term in comparison to that after DG. METHODS: Twenty-six patients who underwent gastrectomy (11 PPG, 15 DG) for early gastric cancer at Osaka University Hospital participated and were followed for more than 4 years. Body weight changes, nutritional status, dual-phase scintigraphy findings, endoscopic survey results, and questionnaire responses after gastrectomy were examined. RESULTS: There were significantly lower ratios of weight changes in PPG than in DG, 5 years after surgery. There were no differences in the clinicopathological characteristics, nutritional parameters, questionnaire responses, and endoscopic findings between the two groups. Based on gastric scintigraphy, although the gastric emptying of liquids showed similar curves in the two groups, gastric emptying of solids was significantly slower in the PPG group than in the DG group (P = .039). DISCUSSION: PPG had advantages with regard to long-term outcomes over DG in terms of weight maintenance and the prevention of rapid gastric emptying. PPG might be efficient in patients with early gastric cancer.

OBJECTIVE: To clarify whether perioperative immunonutrition is effective in adult patients with or without malnutrition undergoing elective surgery for head and neck (HAN) or gastrointestinal (GI) cancers. BACKGROUND: It is important to avoid postoperative complications in patients with cancer as they can compromise clinical outcomes. There is no consensus on the efficacy of perioperative immunonutrition in patients with or without malnutrition undergoing HAN or GI cancer surgery. MATERIALS AND METHODS: We searched MEDLINE (PubMed), MEDLINE (OVID), EMBASE, Cochrane Central Register of Controlled Trials, Web of Science Core Selection, and Emcare from 1981 to 2022 using search terms related to immunonutrition and HAN or GI cancer. We included randomized controlled trials. Intervention was defined as immunonutritional therapy including arginine, n-3 omega fatty acids, or glutamine during the perioperative period. The control was defined as standard nutritional therapy. The primary outcomes were total postoperative and infectious complications, defined as events with a Clavien-Dindo classification grade ≥ II that occurred within 30 days after surgery. RESULTS: Of the 4825 patients from 48 included studies, 19 had upper GI cancer, 9 had lower, and 8 had mixed cancer, whereas 12 had HAN cancers. Immunonutrition reduced the total postoperative complications (relative risk ratio: 0.78; 95% CI, 0.66-0.93; certainty of evidence: high) and infectious complications (relative risk ratio: 0.71; 95% CI, 0.61-0.82; certainty of evidence: high) compared with standard nutritional therapy. CONCLUSIONS: Nutritional intervention with perioperative immunonutrition in patients with HAN and GI cancers significantly reduced total postoperative complications and infectious complications.

Patients with unilateral spatial neglect (USN) commonly experiences stimulus-driven attention deficit characterized by unexpected stimuli detection. We investigated whether virtual reality (VR) balloon search training with the screen background shifted to left space could improve stimulus-driven attention in patients with USN. The participants were divided into two groups: immediate VR group (n = 14) and delayed VR group (n = 14). The immediate VR group first received VR balloon search training, followed by control training, for two weeks each. Delayed VR group received the same training in reverse order. Outcomes were changes in scores on Catherine Bergego Scale (CBS) and reaction time on the modified Posner task (MPT). There was significant improvement in CBS score change after VR balloon retrieval training (all F > 2.71; P < 0.002). In the invalid condition of MPT, significant improvements were shown after VR balloon search training in left-sided reaction time (improvement of stimulation-driven attention). This study shows that VR balloon search training can improve neglect symptoms by using an intensive intervention lasting 2 weeks.
RESUMEN
BACKGROUND/AIM: Monoclonal antibodies (mAbs) that target tumor antigens have recently been developed. Their antitumor activity is mainly achieved through antibody-dependent cellular cytotoxicity (ADCC) via effector cells such as tumor-infiltrated macrophages and natural killer (NK) cells. CpG oligodeoxynucleotides (ODNs) have potent antitumor activity and are considered to increase the tumor infiltration of macrophages and NK cells; however, a completely solubilized novel CpG-schizophyllan (SPG) complex, K3-SPG, displays more potent antitumor activity. We recently reported the significant antitumor activity of anti-glypican-1 (GPC1) mAb against GPC1-positive esophageal squamous cell carcinoma (ESCC) via ADCC. The aim of this study was to evaluate the potential synergistic antitumor activity of anti-GPC1 mAb and K3-SPG and elucidate the underlying mechanisms using a xenograft model of GPC1-positive human ESCC cells. MATERIALS AND METHODS: The established human esophageal cancer cell line TE14 was subcutaneously injected into SCID mice. Xenograft mice were treated with anti-GPC1 mAb, K3-SPG, or their combination. Antitumor activity was evaluated by measuring the tumor volume. For FACS analysis, agents were administrated, and tumors were resected 1 day after the final treatment. RESULTS: Anti-GPC1 mAb or K3-SPG monotherapy showed dose-dependent antitumor activity, and combination therapy with anti-GPC1 mAb and K3-SPG showed antitumor activity (p=0.0859). Flow cytometry revealed significantly increased numbers of macrophages (p=0.0133) and of the ratio of activated NK cells/total NK cells (p=0.0058) following K3-SPG or combination therapy. CONCLUSION: Combination therapy with K3-SPG and anti-GPC1 mAb or another antitumor mAb may represent a new cancer treatment option acting via ADCC.

The patient is a 50s year old man. He visited his local doctor with complaints of anal pain and bloody stools, and a rectal examination revealed a tumor on the anterior wall of the rectal canal. CT imaging showed tumors invading the prostate, urethra, and anorectal muscles, and a 3 mm-sized nodule was found in the lungs. The patient was diagnosed as cT4bN1M1a, Stage â £, and total neoadjuvant chemotherapy was planned as preoperative treatment. The 5 Gy×5 times radiation therapy followed by 5 courses of CAPOX plus BEV as preoperative chemotherapy and CAPOX. CAPOX was administered. After completion of treatment, the colonoscopy showed PR, and MRI showed clear boundary between the prostate and tumor but invasion into the anorectal muscles; CT showed no lung metastasis, and preoperative diagnosis was ycT4bN0M0, ycStage â ¡. Robotic-assisted rectal amputation and left lateral lymph node dissection were performed under general anesthesia. Pathologically, the patient was diagnosed as ycT4bN0M0, Stage â ¡, and the efficacy was determined as TRG 1(AJCC). Vertical dissection was negative and radical resection was possible.

INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) for morbidly obese patients often results in remission of type 2 diabetes (T2DM), but diabetes relapses in some of those patients. The frequency of T2DM relapse in Asians and the factors involved have not been adequately investigated. METHODS: The J-SMART study was conducted on 322 Japanese subjects with body mass index (BMI) ≥32 kg/m2 who underwent LSG at 10 accredited centers in Japan between 2011 and 2014. Of these, 82 T2DM subjects with diabetes in complete or partial remission at 1 year after LSG and followed postoperatively for 5 years were included in the subgroup analysis and classified into two groups: diabetes remission-maintained and diabetes relapse. RESULTS: The mean age of all included subjects was 49.2 years, median BMI was 41.5 kg/m2, and median HbA1c was 6.7%. Compared with the diabetes remission-maintained group, the diabetes relapse group at 5 years after LSG had significantly higher preoperative HbA1c, number of antidiabetic medications, and high-density lipoprotein cholesterol level; and lower BMI and homeostasis model assessment-beta cell function (HOMA-ß). As many as 83.0% of the subjects were able to achieve HbA1c <7% at 5 years after LSG, but 26.8% of the subjects had diabetes relapse. Preoperative HbA1c significantly contributed to diabetes relapse (odds ratio 1.54, p = 0.049). In addition, the diabetes relapse group tended to have lower percentage total weight loss (%TWL) at 1 year after LSG and higher percentage weight regain (%WR) from postoperative nadir weight, compared with the diabetes remission-maintained group. The hazard ratio for diabetes relapse was 3.14-fold higher in subjects with %TWL ≥20% and %WR ≥25%, and 5.46-fold higher in those with %TWL <20% and %WR ≥25%, compared with %TWL ≥20% and %WR <25%. CONCLUSION: While LSG provides a high remission rate for T2DM, relapse is not uncommon. Preoperative HbA1c, poor weight loss, and excess weight regain after LSG contribute to diabetes relapse, suggesting the importance of treatment strategies focusing on these factors.

BACKGROUND: Metabolic and bariatric surgery (MBS) has been established to provide long-term weight loss in severe obesity. In this study, we investigated the factors that affect post-operative weight loss, with a particular focus on changes in eating behaviors. METHODS: Time-course changes in body weight and eating behaviors were examined in 49 Japanese patients who underwent laparoscopic sleeve gastrectomy from the first visit to 12 months after surgery. Each eating behavior was evaluated via the questionnaire of the Japan Society for the Study of Obesity. RESULTS: Pre-operative weight reduction mediated by dietary and lifestyle interventions showed significant positive correlations with weight loss outcomes at 12 months after surgery. We observed significant decreases in scores for most of the eating behaviors 12 months after surgery. However, "emotional eating behavior" scores declined temporarily in the early post-operative period of one month but thereafter returned to the pre-operative level at 12 months. Furthermore, increases in the scores for "emotional eating behavior" and "sense of hunger" from 1 to 12 months post-operatively were significantly associated with poor weight loss. CONCLUSIONS: Our results demonstrate the beneficial effects of MBS on obesity-related eating behaviors, as well as highlighting "emotional eating behavior" as requiring particular attention.

PURPOSE: To determine if functional connectivity measured with resting-state functional MRI could be used as a tool to assess unilateral spatial neglect during stroke recovery. METHODS: Resting-state functional MRI was performed on 13 stroke patients with lesions in the right cerebral hemisphere and 31 healthy subjects. The functional connectivity score was defined as a correlation of a target region with the right inferior parietal lobule. Spatial neglect was measured with a behavioral inattention test. RESULTS: First, the functional connectivity scores between the right inferior parietal lobule and right inferior frontal gyrus, including the opercular and triangular parts, were significantly decreased in stroke patients with unilateral spatial neglect compared with patients without unilateral spatial neglect and were significantly correlated with the behavioral inattention test score. Second, the functional connectivity scores between the bilateral inferior parietal lobules were also significantly decreased in patients with unilateral spatial neglect compared with patients without unilateral spatial neglect and were significantly correlated with the behavioral inattention test score. Third, negative functional connectivity scores between the right inferior parietal lobule and bilateral medial orbitofrontal cortexes, which are related to the default mode network, were detected in patients without unilateral spatial neglect in contrast to a reduction of this negative tendency in patients with unilateral spatial neglect. The functional connectivity scores between these regions were significantly different between patients with and without unilateral spatial neglect and were negatively correlated with the behavioral inattention test score. CONCLUSION: Though still in the pilot research stage and using a small number of cases, our findings are consistent with the hypothesis that functional connectivity maps generated with resting-state functional MRI may be used as a tool to evaluate unilateral spatial neglect during stroke recovery.

BACKGROUND: Accelerated tumor growth during immunotherapy in pre-existing measurable lesions, hyperprogressive disease (HPD), has been reported. However, progression of non-measurable lesions and new lesions are frequently observed in patients with advanced gastric cancer (AGC). METHODS: This retrospective study involved AGC patients at 24 Japanese institutions who had measurable lesions and received nivolumab after ≥ 2 lines of chemotherapy. HPD was defined as a ≥ two-fold increase in the tumor growth rate of measurable lesions. The pattern of disease progression was classified according to new lesions in different organs and ascites appeared/increase of ascites. RESULTS: Of 245 patients, 147 (60.0%) showed progressive disease (PD) as the best response and 41 (16.7%) showed HPD during nivolumab monotherapy. There was no significant difference in overall survival (OS) between patients with HPD and those with PD other than HPD (median OS 5.0 vs 4.8 months; hazard ratio [HR] 1.0, 95% confidence interval [CI] 0.6-1.5; p = 1.0). Fifty-three patients developed new lesions in different organs and 58 had appearance/increase of ascites; these patients showed shorter OS than those without each of these features (median OS 3.3 vs 7.1 months, HR 1.8, 95% CI 1.2-2.7, p = 0.0031 for new lesions, and 3.0 vs 7.8 months, HR 2.6, 95% CI 1.8-3.8, p < 0.0001 for ascites). Thirty-one patients who had both features showed the worst prognosis (median OS 2.6 months). CONCLUSIONS: New lesions in different organs and appearance/increase of ascites, rather than the original definition of HPD, are the patterns of disease progression associated with poor prognosis in AGC patients receiving nivolumab whose best response was PD.

A female in her 70s underwent right hepatectomy with resection of caudate lobe and extrahepatic bile duct for perihilar cholangiocarcinoma(T2aN0M0, Stage â ¡: Biliary Cancer Treatment Regulations, 7th edition). On the 4th postoperative day, the patient had impaired consciousness, which worsened to almost coma on the 5th postoperative day. On the same day, a blood test showed high ammonia level, thus the state was thought to be hepatic encephalopathy. Contrast -enhanced CT on the same day showed thrombus from the main trunk of the portal vein to the remnant left branch, narrowing of the lumen of the vessel. Simultaneously, enlarged portosystemic shunt in the pelvic floor due to portal hypertension induced by the thrombosis. Plasmapheresis was performed, and anticoagulation with sodium heparin and antithrombin â ¢ were started. Then, the portal vein thrombus was reduced, and encephalopathy was improved. She was discharged from the hospital on postoperative day 48. She was treated with edoxaban as an outpatient, and anticoagulation therapy was terminated after a CT scan 6 months after surgery, which confirmed no recurrence of thrombus. She is now alive without recurrence of thrombus or tumor for about 2 years after the surgery.

The patient is a 70s woman. She underwent cystectomy for bladder cancer 6 years ago and had a ureterocutaneous fistula in the right lower abdomen. After colonoscopy for positive fecal occult blood, a type 1 elevated lesion was found in the ascending colon, which was diagnosed as a well-differentiated adenocarcinoma on biopsy. Surgery was performed with a single hole. The approach from the right lower abdomen, where the ureterocutaneous fistula and ureter are located, was avoided, and the approach from the hepatic flexure of the transverse colon was used first.
