RESUMEN
BACKGROUND: Pancreatoduodenectomy and subtotal esophagectomy are widely considered the most invasive and difficult surgical procedures in gastrointestinal surgery. Subtotal esophagectomy after pancreatoduodenectomy is expected to be extremely difficult due to complicated anatomical changes, and selecting an appropriate intestinal reconstruction method will also be a difficult task. Therefore, perhaps because the method is considered impossible, there have been few reports of subtotal esophagectomy after pancreatoduodenectomy. CASE PRESENTATION: A 73-year-old man with a history of pancreatoduodenectomy was diagnosed with superficial thoracic esophageal squamous cell carcinoma. Definitive chemoradiation therapy was recommended at another hospital; however, he visited our department to undergo surgery. We performed the robot-assisted thoracoscopic subtotal esophagectomy. There were some difficulties with the reconstruction: the gastric tube could not be used, the reconstruction was long, and the organs reconstructed in the previous surgery had to be preserved. However, the concurrent reconstruction was achieved with the help of a free jejunal flap and vascular reconstruction. All reconstructions from the previous surgery, including the remnant stomach, were preserved via regional abdominal lymph node dissection. After reconstruction, intravenous indocyanine green showed that circulation in the reconstructed intestines was preserved. On postoperative day 1, no recurrent nerve paralysis was observed during laryngoscopy. The patient could start oral intake smoothly 2 weeks after surgery and did not exhibit any postoperative complications related to the reconstruction. The patient was transferred to another hospital on postoperative day 21. CONCLUSIONS: Owing to the free jejunal flap interposition method, we safely performed one stage subtotal esophagectomy and concurrent reconstruction, preservation of the remnant stomach, and pancreaticobiliary reconstruction in patients with a history of pancreatoduodenectomy. We believe that this method is acceptable and useful for patients undergoing complicated reconstruction.
RESUMEN
Post-gastrectomy syndrome (PGS) and body weight loss (BWL) decrease quality of life (QOL) and survival of the patient undergoing gastrectomy. We have introduced perioperative and post-discharge continuous nutritional counseling (CNC) to prevent BWL and improve QOL after gastrectomy. In the present study, we evaluated the effect of CNC on QOL using the Post-gastrectomy Syndrome Assessment Scale-45 (PGSAS-45). Eighty-three patients with gastric cancer (GC) who underwent curative gastrectomy between March 2018 and July 2019 were retrospectively analyzed. Patients received either pre-discharge nutritional counseling alone (control group, n = 45) or CNC (CNC group, n = 38) after gastrectomy. QOL at 12 months after gastrectomy was compared between the two groups. In QOL assessment, change in body weight (-7.98% vs. -12.77%, p = 0.0057), ingested amount of food per meal (7.00 vs. 6.07, p = 0.042) and ability for working (1.89 vs. 2.36, p = 0.049) were significantly better in CNC group than control group. Multiple regression analysis showed that CNC was a significantly beneficial factor for abdominal pain subscale (p = 0.028), diarrhea subscale (p = 0.047), ingested amount of food per meal (p = 0.012), Ability for working (p = 0.031) and dissatisfaction at the meal (p = 0.047). Perioperative and postoperative CNC could improve QOL in the patient undergoing gastrectomy in addition to preventing postoperative BWL.

INTRODUCTION AND IMPORTANCE: A parahiatal hernia (PH) is a rare diaphragmatic hernia (DH) adjacent to but separated from the esophageal hiatus. The surgical repair for PH needs primary suture closure or complicated hernioplasty and the addition of an anti-reflux procedure. This report describes a case of PH with a symptomatic esophageal hiatal hernia managed using three-dimensional (3D) laparoscopy. CASE PRESENTATION: A 65-year-old woman with back pain and breathlessness was referred to our hospital for a DH. Computed tomography showed a diaphragmatic defect on the left side of the esophageal hiatus. Upper gastrointestinal endoscopy and 24-hour esophageal impedance-pH monitoring showed a symptomatic esophageal hiatal hernia. Laparoscopic repair for both hernias was performed using 3D laparoscopy. The DH orifice was located in the left crus of the diaphragm, and it was separated from the esophageal hiatus. These findings showed that this DH was a PH. The PH was repaired with primary suturing, and a hiatoplasty was performed. Toupet fundoplication was performed with a 270° posterior wrap of the gastric fornix. The patient has remained asymptomatic a year after surgery without any complications. CLINICAL DISCUSSION: 3D laparoscopy provides significant advantages in surgeries requiring precise suturing. PH repairs require complex procedures, including mesh repair or suturing. Approximately 44 % of PH cases also necessitate fundoplication. 3D laparoscopy was useful for the present case. CONCLUSIONS: A rare PH and a symptomatic type 1 hiatal hernia were repaired with 3D laparoscopy, which is helpful for PH treatment in cases requiring complicated procedures.
RESUMEN
The programmed cell death 1 protein (PD-1)/programmed cell death ligand 1 (PD-L1) axis plays a crucial role in tumor immunosuppression, while the cancer-associated fibroblasts (CAFs) have various tumor-promoting functions. To determine the advantage of immunotherapy, the relationship between the cancer cells and the CAFs was evaluated in terms of the PD-1/PD-L1 axis. Overall, 140 cases of esophageal cancer underwent an immunohistochemical analysis of the PD-L1 expression and its association with the expression of the α smooth muscle actin, fibroblast activation protein, CD8, and forkhead box P3 (FoxP3) positive cells. The relationship between the cancer cells and the CAFs was evaluated in vitro, and the effect of the anti-PD-L1 antibody was evaluated using a syngeneic mouse model. A survival analysis showed that the PD-L1+ CAF group had worse survival than the PD-L1- group. In vitro and in vivo, direct interaction between the cancer cells and the CAFs showed a mutually upregulated PD-L1 expression. In vivo, the anti-PD-L1 antibody increased the number of dead CAFs and cancer cells, resulting in increased CD8+ T cells and decreased FoxP3+ regulatory T cells. We demonstrated that the PD-L1-expressing CAFs lead to poor outcomes in patients with esophageal cancer. The cancer cells and the CAFs mutually enhanced the PD-L1 expression and induced tumor immunosuppression. Therefore, the PD-L1-expressing CAFs may be good targets for cancer therapy, inhibiting tumor progression and improving host tumor immunity.

PURPOSE: It remains unknown whether stroke volume variation (SVV), pulse pressure variation (PPV), and dynamic arterial elastance (Eadyn) are suitable for monitoring fluid management during thoracoscopic esophagectomy (TE) in the prone position with one-lung ventilation and artificial pneumothorax. Our study aimed to evaluate the accuracy of SVV, PVV, and Eadyn in predicting the fluid responsiveness in these patients. METHODS: We recruited 24 patients who had undergone TE. Patients with a mean arterial blood pressure ≤ 65 mmHg received a 200-ml bolus of 6% hydroxyethyl starch over 10 min. Fluid responders showed the stroke volume index ≥ 15% 5 min after the fluid bolus. Receiver operating characteristic (ROC) curves were generated and area under the ROC curve (AUROC) was calculated. RESULTS: We obtained 61 fluid bolus data points, of which 20 were responders and 41 were non-responders. The median SVV before the fluid bolus in responders was significantly higher than that in non-responders (18% [interquartile range (IQR) 13-21] vs. 12% [IQR 8-15], P = 0.001). Eadyn was significantly lower in responders than in non-responders (0.55 [IQR 0.45-0.78] vs. 0.91 [IQR 0.67-1.00], P < 0.001). There was no difference in the PPV between the groups. The AUROC was 0.76 for SVV (95% confidence interval [CI] 0.62-0.89, P = 0.001), 0.56 for PPV (95% CI 0.41-0.71, P = 0.44), and 0.82 for Eadyn (95% CI 0.69-0.95, P < 0.001). CONCLUSIONS: SVV and Eadyn are reliable parameters for predicting fluid responsiveness in patients undergoing TE.

BACKGROUND: In Japan, about 6% of esophageal cancers are adenocarcinomas, although most of them arise from Barrett's epithelium. Adenocarcinoma arising from heterotopic gastric mucosa (HGM) is very rare. Due to its rarity, there is no unified view on its treatment strategy and prognosis. CASE PRESENTATION: A 57-year-old man presented with a protruding lesion in the cervicothoracic esophagus that was detected by an upper gastrointestinal series at a medical checkup. Esophagoscopy revealed a 30 mm Type 1 tumor circumferentially surrounded by widespread HGM. Computed tomography (CT) and fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT showed no metastasis or invasion of the surrounding organs. We diagnosed the lesion as cT2N0M0 cStageIIB [Union for International Cancer Control (UICC) 8th Ed] cancer and performed subtotal esophagectomy with three-field lymph node dissection. The tumor was determined to be a well-differentiated adenocarcinoma arising from HGM, with deep invasion of the submucosa. The patient underwent no adjuvant therapy and has currently survived without any evidence of recurrence for 15 months. CONCLUSIONS: Although the treatment for adenocarcinoma arising from HGM is basically the same as that for squamous cell carcinoma (SCC) of the esophagus, it is important to determine the treatment strategy based on the characteristics of the adenocarcinoma arising from HGM.
RESUMEN
BACKGROUND: The prognosis of esophageal cancer (EC) with organ invasion is extremely poor. In these cases, definitive chemoradiotherapy (CRT) followed by salvage surgery can be planned; however, the issue of high morbidity and mortality rates persists. Herein, we report the long-term survival of a patient with EC and T4 invasion who underwent a modified two-stage operation after definitive CRT. CASE PRESENTATION: A 60-year-old male presented with type 2 upper thoracic EC with tracheal invasion. First, definitive CRT was performed, which resulted in tumor shrinkage and improvement in the tracheal invasion. However, an esophagotracheal fistula subsequently developed, and the patient was treated with fasting and antibiotics. Although the fistula recovered, severe esophageal stenoses made oral intake impossible. To improve quality of life and cure the EC, a modified two-stage operation was planned. In the first surgery, an esophageal bypass was performed using a gastric tube with cervical and abdominal lymph node dissections. After confirming improved nutritional status and absence of distant metastasis, the second surgery was performed with subtotal esophagectomy, mediastinal lymph node dissection, and tracheobronchial coverage of the fistula. The patient discharged without major complications after radical resection and has been recurrence-free for 5 years since the start of treatment. CONCLUSION: A standard curative strategy could be difficult for EC with T4 invasion due to differences in the invaded organs, presence of complications, and patient condition. Therefore, patient-tailored treatment plans are needed, including a modified two-stage operation.
RESUMEN
BACKGROUND: This study aimed to determine whether nutritional education, from the preoperative to postoperative period, and nutritional management designed to improve nutritional status alone, could improve patients' health-related self-management and nutritional management skills during the postoperative period. METHODS: We evaluated 101 hospitalised patients with oesophageal cancer who underwent surgery between 2015 and 2016 and received perioperative nutritional education (PERIO-N). The control group included 52 patients who underwent surgery between 2014 and 2015 and were supported only by normal interventions according to the Enhanced Recovery After Surgery protocol. The PERIO-N group paid specific attention to nutrition risk screening, nutrition assessment, nutrition monitoring, and lifestyle education. RESULTS: The patients in the PERIO-N group were 1.8 times more likely to be able to consume food orally than the control group (p=0.010). In the PERIO-N group, 50.5% of the patients could orally consume food, 42.6% received a combination of oral and enteral nutrition, and 6.9% only underwent enteral nutrition. In comparison, in the control group, 28.8% of the patients could orally consume food, 53.8% received a combination of oral and enteral nutrition, and 17.3% were only administered enteral nutrition (p=0.004). In addition, patients in the PERIO-N group were discharged at a 1.5 times higher rate than those in the control group (p=0.027). The readmission rate for malnutrition within 3 months was 4% in the PERIO group (5.4% for home discharge only) and 5.8% in the control group (10.5% for home discharge only) (p=0.61). CONCLUSION: This study found that perioperative nutrition education in patients who underwent oesophageal cancer surgery led to increase in the amount of oral intake at discharge. Moreover, the group that received nutrition education did not have an increased probability of hospitalisation due to the risk of malnutrition within 3 months after discharge.

Esophageal neuroendocrine carcinoma (E-NEC) is an aggressive disease with a poor prognosis. The present study aimed to assess the role of surgery in the treatment of patients with resectable E-NEC, and identify a microRNA (miRNA/miR) signature in association with positive postoperative outcomes. Between February 2017 and August 2019, 36 patients with E-NEC who underwent curative surgery at the Japan Neuroendocrine Tumor Society partner hospitals were enrolled in the study. A total of 16 (44.4%) patients achieved disease-free survival (non-relapse group), whereas 20 (55.6%) patients developed tumor relapse (relapse group) during the median follow-up time of 36.5 months (range, 1-242) after surgery with a 5-year overall survival rate of 100 and 10.8%, respectively (P<0.01). No clinicopathological parameters, such as histological type or TNM staging, were associated with tumor relapse. Microarray analysis of 2,630 miRNAs in 11 patients with sufficient quality RNA revealed 12 miRNAs (miR-1260a, -1260b, -1246, -4284, -612, -1249-3p, -296-5p, -575, -6805-3p, -12136, -6822-5p and -4454) that were differentially expressed between the relapse (n=6) and non-relapse (n=5) groups. Furthermore, the top three miRNAs (miR-1246, -1260a and -1260b) were associated with overall survival (P<0.01). These results demonstrated that surgery-based multidisciplinary treatment is effective in a distinct subpopulation of limited stage E-NEC. A specific miRNA gene set is suggested to be associated with treatment outcome.
RESUMEN
BACKGROUND: Surgical resection of esophageal cancer is frequently performed to achieve a complete cure. However, the postoperative recurrence rate is 36.8-42.5%, leading to poor prognosis. Radiation therapy has been used to treat recurrences; solitary recurrence has been proposed as a prognostic factor for radiation therapy, though its significance is unclear. 18F-fluorodeoxyglucose positron emission tomography is a highly accurate diagnostic modality for esophageal cancer. This retrospective study aimed to analyze the outcomes of solitary postoperative recurrences of esophageal squamous cell carcinoma diagnosed with 18F-fluorodeoxyglucose positron emission tomography and treated with definitive radiation therapy. METHODS: We examined 27 patients who underwent definitive radiation therapy for single or multiple postoperative recurrences of esophageal squamous cell carcinoma between May 2015 and April 2021. 18F-fluorodeoxyglucose positron emission tomography/computed tomography was performed within 3 months before the commencement of radiation therapy. Kaplan-Meier, univariate, and multivariate analyses were performed to examine the overall survival and identify potential prognostic factors. RESULTS: The 1-, 2-, and 3-year overall survival rates were 85.2%, 62.6%, and 47.3%, respectively, and solitary recurrence was the only significant factor associated with overall survival (P = 0.003). The 1-, 2-, and 3-year overall survival rates in patients with solitary recurrence were 91.7%, 80.2%, and 80.2%, respectively, and in patients with multiple recurrences they were 80.0%, 50.3%, and 25.1%, respectively. Multivariate analysis also showed solitary recurrence as a significant factor for overall survival. CONCLUSIONS: When diagnosed with 18F-fluorodeoxyglucose positron emission tomography/computed tomography, solitary recurrence appears to have a more favorable prognosis than multiple recurrences.

This retrospective study aimed to investigate the validity of a 30-sec chair stand test (CS-30) as a simple test to assess exercise tolerance and clinical outcomes in 53 Japanese patients with esophageal cancer. There was a strong correlation between the results of CS-30 and the 6-min walk test (6MWT), the gold standard for assessing exercise tolerance (r=0.759). Furthermore, fewer patients whose CS-30 score was greater than 16 (the cutoff value defined based on 6MWT) experienced pneumonia in their postoperative course. These results suggest that exercise tolerance could be assessed using CS-30, and its cutoff value may be useful in predicting postoperative pneumonia risk.

Cancer-associated fibroblasts (CAFs) are a critical component of the tumor microenvironment and play a central role in tumor progression. Previously, we reported that CAFs might induce tumor immunosuppression via interleukin-6 (IL-6) and promote tumor progression by blocking local IL-6 in the tumor microenvironment with neutralizing antibody. Here, we explore whether an anti-IL-6 receptor antibody could be used as systemic therapy to treat cancer, and further investigate the mechanisms by which IL-6 induces tumor immunosuppression. In clinical samples, IL-6 expression was significantly correlated with α-smooth muscle actin expression, and high IL-6 cases showed tumor immunosuppression. Multivariate analysis showed that IL-6 expression was an independent prognostic factor. In vitro, IL-6 contributed to cell proliferation and differentiation into CAFs. Moreover, IL-6 increased hypoxia-inducible factor 1α (HIF1α) expression and induced tumor immunosuppression by enhancing glucose uptake by cancer cells and competing for glucose with immune cells. MR16-1, a rodent analog of anti-IL-6 receptor antibody, overcame CAF-induced immunosuppression and suppressed tumor progression in immunocompetent murine cancer models by regulating HIF1α activation in vivo. The anti-IL-6 receptor antibody could be systemically employed to overcome tumor immunosuppression and improve patient survival with various cancers. Furthermore, the tumor immunosuppression was suggested to be induced by IL-6 via HIF1α activation.

Salvage surgery for esophageal cancer after definitive chemoradiotherapy (dCRT) is effective, but it is associated with a high rate of perioperative complications. The indications for robot-assisted minimally invasive esophagectomy (RAMIE) are expanding. However, there are few reports of salvage RAMIE. A 73-year-old man was referred to our hospital for residual esophageal cancer with a mediastinal fistula after dCRT. The perioperative diagnosis was T3N1M0-Stage III, and the salvage RAMIE was performed. Although the dissection was difficult due to fibrosis caused by dCRT and the esophageal mediastinal fistula, RAMIE was performed safely with no complications. Multiple features of RAMIE contributed to stable surgery. The monopolar dissection is effective for hard scar tissue caused by CRT and inflammation.

BACKGROUND: Body weight loss (BWL) and skeletal muscle loss (SML) are inevitable after gastrectomy for gastric cancer (GC) and can decrease patients' quality of life (QOL) and survival. OBJECTIVE: The aim of this retrospective study was to evaluate the effect of perioperative and post-discharge patient participation in continuous nutritional counseling (CNC) on post-gastrectomy BWL and SML. METHODS: Ninety-three patients with GC who underwent curative gastrectomy between March 2018 and July 2019 were analyzed. Patients received either pre-discharge nutritional counseling alone (control group, n = 49) or patient-participation CNC (CNC group, n = 44) after gastrectomy. Differences between percentage BWL (%BWL), percentage SML (%SML), and nutrition-related blood parameters between the preoperative values and those at 12 months after surgery were compared between the groups. RESULTS: Compared with the control group, %BWL was significantly lower in the CNC group at 1 month (-6.2 ± 2.5% vs. -7.9 ± 3.3%, p = 0.005), 6 months (-7.8 ± 6.6% vs. -12.3 ± 6.4%, p = 0.001) and 12 months (-7.9 ± 7.6% vs. -13.2 ± 8.2%, p = 0.002), and %SML was significantly lower in the CNC group at 12 months (-5.3 ± 10.3% vs. -12.8 ± 12%, p = 0.002). Regarding nutrition-related blood parameters, change in total cholesterol was significantly lower in the CNC group than the control group at 12 months after surgery (p = 0.02). Multivariate analysis identified no CNC as an independent risk factor for severe BWL (p = 0.001) and SML (p = 0.006) at 12 months after surgery. CONCLUSIONS: Following gastrectomy, patient-participation CNC prevented postoperative BWL and SML after surgery. These results support the induction of such a CNC program in these patients.

BACKGROUND/AIM: For patients with T1a muscularis mucosae (MM) esophageal squamous cell carcinoma (ESCC) with lymphovascular invasion (LVI) or T1b submucosal (SM) ESCC, endoscopic resection is non-curative, and adjuvant treatment entailing esophagectomy or definitive chemoradiotherapy is necessary. This is because about 30% of these cases have lymph node (LN) metastasis. The purpose of this study was to test the utility of a CRP genetic polymorphism test kit for determining the risk of LN metastasis with the aim of eliminating additional invasive adjuvant therapy. PATIENTS AND METHODS: This is a retrospective, multi-institutional, observational study. The CRP 1846C>T genetic polymorphisms were identified using a fully automated genotyping system. The primary end points were an 85% negative predictive value (NPV) for diagnosis of LN metastasis in pT1a (MM) and 80% NPV in pT1b (SM1) patients. RESULTS: A total of 742 ESCC (105 pMM, 166 pSM1 and 471 pSM2-3) patients who had received esophagectomy with 2- or 3-field LN dissection at 65 institutions were enrolled. According to this test, patients with the C/C and C/T genotypes were considered to be low risk. The NPVs using this test were 82.8% in pMM and 71.7% in pSM1 patients. CONCLUSION: CRP 1846C>T genetic polymorphism is not a useful diagnostic indicator for determining the risk of LN metastasis; however, the possibility that CRP gene polymorphisms are involved in the mechanism of lymph node metastasis in solid tumors still remains.

BACKGROUND: The standard treatment for locally advanced esophageal cancer is preoperative chemotherapy with cisplatin and 5-fluorouracil (CF), followed by surgery. Although docetaxel plus cisplatin and 5-fluorouracil (DCF) has been reported to have favorable outcomes, no study has compared its therapeutic efficacy to that of standard treatment. This study aimed to compare the therapeutic effects of CF and DCF in the real world by matching patient background factors using propensity scores. METHODS: We retrospectively reviewed the data of 237 patients with esophageal squamous cell carcinoma who underwent esophagectomy between January 2008 and December 2018. Patients were divided into two groups based on the preoperative chemotherapy regimens of CF (79 patients) or DCF (158 patients), and 49 matched pairs were finally analyzed using propensity score matching. Short- and long-term outcomes were compared between groups. RESULTS: After matching, although no significant differences in survival were observed among the groups, patients receiving DCF showed a significantly high histological response (P < 0.001). Subgroup analyses demonstrated that DCF therapy had better overall survival (P = 0.046) and relapse-free survival (P = 0.010) among pathological T3 and T4 cases. Whereas, adverse effects of chemotherapy were more frequent in the DCF group. CONCLUSIONS: Patients receiving DCF had higher pathological response and better survival than those receiving CF, especially in pathological T3 and T4 cases matched using propensity scores. Thus, the DCF regimen might be an effective treatment for locally advanced esophageal cancer. However, the adverse side effects of chemotherapy remain high and should be handled appropriately.

BACKGROUND: Verrucous carcinoma of the esophagus (VCE) is a rare tumor that is difficult to diagnose. In most cases, biopsies show nonspecific inflammatory and hyperkeratotic changes and do not show malignant findings. Most VCEs are slowly growing, locally advanced tumors with few metastases. Treatments for VCE are the same as for normal esophageal cancer, involving combined chemotherapy, surgical resection, and radiation therapy. However, it has been reported that VCE has a poor response to radiation or chemoradiotherapy (CRT). A case of VCE with complete response (CR) after CRT is presented. CASE PRESENTATION: A 70-year-old man was found to have white, irregular esophageal mucosa 4 years earlier. He had been followed up as an outpatient as having candidal esophagitis. However, his tumor grew gradually, and biopsy was performed by endoscopic mucosal resection (EMR). He was finally diagnosed with VCE. He had no metastases to distant organs, but some lymph node metastases were suspected. The tumor invaded his left bronchus. The esophagostomy and gastrostomy were constructed as emergent procedures. The patient then underwent definitive CRT. 4 weeks after the end of CRT, two-stage esophagectomy was performed. First, he underwent esophagectomy with thoracic lymph node dissection. A latissimus dorsi flap was patched to the bronchus after primary suture of the hole. 6 weeks later, reconstruction of the gastric tube was performed through the antethoracic route. The pathological findings showed CR to CRT, with no proliferative cancer cells in the specimen. The patient has had no recurrence for three and half years after the resection. CONCLUSIONS: We presented a locally advanced VCE that achieved CR to CRT. In cases that have some difficulty for local resection, CRT might be an appropriate treatment for VCE.
RESUMEN
BACKGROUND/AIM: Postoperative body weight loss (BWL) and skeletal muscle loss (SML) after gastrectomy are associated with a decline in quality of life and worse longterm prognosis in gastric cancer (GC) patients. This study aimed to evaluate the efficacy of amino acids nutrition on BWL and SML in the early period following gastrectomy. PATIENTS AND METHODS: The parameters of body composition were measured by bioelectrical impedance analysis in the patients undergoing radical gastrectomy for GC and analyzed retrospectively. Patients received either peripheral parenteral nutrition (PPN) of 4.3% glucose fluid with regular diet (control group, n=43) or PPN of 7.5% glucose fluid containing amino acids plus oral nutritional supplement (ONS) rich in protein with regular diet (amino acids group, n=40) following gastrectomy. The percentages of BWL and SML from preoperative values to those at 7 days and 1 month after surgery were compared between the two groups. RESULTS: The %BWL and %SML at 7 days after surgery were significantly lower in the amino acids group than those in the control group (%BWL, -2.4±1.7% vs. -4.2±1.8%; p<0.0001, %SML, -4.1±3.8 vs. -6.5±3.8; p=0.006). Moreover, the %BWL at 1 month after surgery was significantly lower in the amino acids group compared to that in the control group (- 4.6±2.9% vs. -6.1±2.6%; p=0.01); however, the %SML was similar between the two groups. The hematological nutritional parameters were similar between the two groups. CONCLUSION: Amino acids nutrition by PPN and ONS following gastrectomy prevented postoperative BWL and SML in the early period after surgery in GC patients.

PURPOSE: To investigate if early exercise can help prevent skeletal muscle loss and improve the clinical outcomes of esophageal cancer patients receiving preoperative neoadjuvant chemotherapy (NAC). METHODS: This was a single-center, retrospective observational cohort study of 110 patients with advanced esophageal cancer. We analyzed the effect of early exercise on the risk of skeletal muscle loss (defined as > 2.98%) during NAC and the subsequent clinical outcomes. Patients in the early exercise group (n = 71) started exercise therapy 8 days earlier than those the late exercise group (n = 39). RESULTS: The median age of the patients was 65.4 years, the mean BMI was 21.1 kg/m2, and 92 (84%) of the 110 patients were men. Skeletal muscle loss occurred in 34% and 67% of the early and late exercise groups, respectively (p < 0.001). There was a lower risk of surgical site infection in the early exercise group (1% vs 16%, p = 0.021). Multivariate analysis revealed that early exercise reduced the risk of skeletal muscle loss (OR = 0.25, 95% CI 0.09-0.65, p = 0.006). CONCLUSIONS: Our results suggest that early exercise reduces the risk of both skeletal muscle loss during NAC and subsequent surgical site infection in patients with esophageal cancer.
