RESUMO

BACKGROUND/AIM: To evaluate the outcomes of curative resection for Borrmann type IV gastric cancer through an analysis of the clinical, surgical and pathological data and through identifying which of these prognostic factors are associated with survival. PATIENTS AND METHODS: We retrospectively analyzed 2798 patients who had undergone excision of the primary lesion and 122 patients with type IV gastric cancer undergoing curative resection (R0 or 1) at Yokohama City University Hospital and Kanagawa Cancer Center between November 1995 and May 2016. RESULTS: Borrmann type IV gastric cancer had more advanced and unfavorable clinicopathological factors compared to other types. The 5-year overall survival rate was 28%, and the median survival was 21.8 months. The overall survival rate was influenced by the depth of invasion, lymph node metastasis, peritoneal lavage cytology (CY), stage and intraoperative blood loss. Of these, independent prognostic factors were intraoperative blood loss (<400 vs. ≥400 ml, risk ratio 1.64; p=0.045) and CY (0 vs. 1, risk ratio 2.25; p=0.004). CONCLUSION: The control of intraoperative bleeding had a positive impact on the survival of patients receiving curative resection for Borrmann type IV gastric cancer.

RESUMO

BACKGROUND: Surgery for gastric cancer should be performed as soon as possible after diagnosis. However, sometimes the waiting time for surgery tends to be longer. The relation between the waiting time for surgery and survival in patients with gastric cancer remains to be fully investigated. METHODS: This retrospective, single-center cohort study evaluated patients with gastric cancer who underwent curative surgery from 2006 through 2012 at Kanagawa Cancer Center in Japan. Patients who received neoadjuvant chemotherapy were excluded. The waiting time for surgery was defined as the time between the first visit and surgery. We investigated whether the waiting time for surgery has a linear negative impact on outcomes by using a Cox regression model with clinical prognostic factors. RESULTS: In total, 801 patients were eligible. The median waiting time was 45 days (range 10-269 days). The restricted cubic spline regression curve showed that the adjusted time-specific hazard ratios of waiting times did not indicate a linear negative trend on survival between 20 and 100 days (p = 0.759). In the Cox model with a quartile of waiting times, waiting times in the 32-44-day group, 43-62-day group, and ≥63 day groups were not associated with poorer overall survival as compared with the ≤31 day group (HR: 1.01, 95% CI 0.63-1.60, p = 0.984, HR: 1.17, 95% CI 0.70-1.94, p = 0.550, HR: 1.06, 95% CI 0.60-1.88, p = 0.831, respectively). CONCLUSIONS: There was no negative relation between the waiting time for surgery (within 100 days) and survival in patients with gastric cancer.

RESUMO

BACKGROUND: Laparoscopic gastrectomy is becoming more commonly performed, but acquisition of its technique remains challenging. We investigated whether laparoscopy-assisted distal gastrectomy (LDG) performed by trainees (TR) supervised by a technically qualified experienced surgeon (QS) is feasible and safe. METHODS: The short-term outcomes of LDG were assessed in patients with gastric cancer between 2008 and 2018. We compared patients who underwent LDG performed by qualified experienced surgeons (QS group) with patients who underwent LDG performed by the trainees (TR group). RESULTS: The operation time was longer in the TR group than in the QS group (median time: 270 min vs. 239 min, p < 0.001). The median duration of the postoperative hospital stay was 9 days in the QS group and 8 days in the TR group (p = 0.003). The incidence of postoperative complications did not differ significantly between the two groups. Grade 2 or higher postoperative complications occurred in 18 patients (12.9%) in the QS group and 47 patients (11.7%) in the TR group (p = 0.763). Grade 3 or higher postoperative complications occurred in 9 patients (6.4%) in the QS group and 17 patients (4.2%) in the TR group (p = 0.357). Multivariate analysis showed that the American Society of Anesthesiologist Physical Status was an independent predictor of grade 2 or higher postoperative complications and that gender was an independent predictor of grade 3 or higher postoperative complications. The main operator (TR/QS) was not an independent predictor of complications. CONCLUSIONS: Laparoscopy-assisted distal gastrectomy performed by trainees supervised by an experienced surgeon is a feasible and safe procedure similar to that performed by experienced surgeons.

RESUMO

BACKGROUND: Laparoscopy-assisted distal gastrectomy (LADG) is increasingly being used as an alternative to open distal gastrectomy (ODG) for gastric cancer treatment. Retrospective studies have shown equivalent survival with the two procedures, but these studies are limited by selection bias because LADG is more technically difficult than ODG. We aimed to evaluate whether LADG was non-inferior to ODG in terms of long-term survival outcomes. METHODS: We did an open-label, multicentre, non-inferiority, phase 3 randomised controlled trial at 33 institutions in Japan. Patients aged 20-80 years with histologically confirmed gastric adenocarcinoma (T1N0, T1N1, or T2[MP]N0), clinical stage I, in the middle or lower third of the stomach, Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, with a body-mass index of less than 30 kg/m2, were randomly assigned (1:1) to receive ODG or LADG. Randomisation was done by telephone, fax, or with a web-based system in the Japan Clinical Oncology Group Data Center; a minimisation method with a random component was used to adjust for institution and clinical stage (IA or IB). Only study-accredited surgeons performed ODG and LADG. The primary endpoint was relapse-free survival and was analysed according to the intention-to-treat principle. The non-inferiority margin (LADG vs ODG) was set at a hazard ratio (HR) of 1·54. The trial was registered with the UMIN Clinical Trials Registry, UMIN000003319. FINDINGS: Between March 15, 2010, and Nov 29, 2013, 921 patients were enrolled and randomly assigned to receive ODG (n=459) or LADG (n=462). 912 (99%) participants had the assigned surgery. 5-year relapse-free survival was 94·0% (95% CI 91·4-95·9) in the ODG group and 95·1% (92·7-96·8) in the LADG group. LADG was non-inferior to ODG for relapse-free survival (HR 0·84 [90% CI 0·56-1·27]), p=0·0075). The most common grade 3 or 4 adverse event was bowel obstruction, occurring in 11 (2%) of 455 patients in the ODG group and five (1%) of 457 patients in the LADG group. There were no treatment-related deaths. INTERPRETATION: This trial supports the non-inferiority of LADG compared with ODG for clinical stage I gastric cancer relapse-free survival, suggesting that LADG should be considered a standard treatment option when performed by experienced surgeons.

RESUMO

PURPOSE: The enzymes gamma-glutamyl hydrolase (GGH) and folylpolyglutamate synthetase (FPGS) regulate intracellular folate concentrations needed for cell proliferation, DNA synthesis, and repair. High GGH expression affects 5-FU thymidylate synthase (TS) inhibition and is a risk factor for various malignancies. Here, the clinical significance of GGH and FPGS expression was investigated in Stage II/III gastric cancer patients undergoing postoperative adjuvant chemotherapy with S-1. METHODS: Surgical specimens of cancer tissue and adjacent normal mucosa, obtained from 253 patients with previously untreated gastric cancer, were examined. GGH and FPGS mRNA expression was measured by qPCR to evaluate their clinicopathological significance in gastric cancer patients after curative resection. RESULTS: While FPGS expression showed no significant differences between the cancerous and normal samples, GGH expression was higher in cancer tissue than in adjacent normal mucosa. High GGH expression was correlated with age, histological type, and vascular invasion. Overall survival (OS) of patients with high GGH mRNA expression was significantly poorer than of patients with low GGH expression. Multivariate analysis showed that high GGH expression was an independent prognostic factor of OS (HR: 2.58, 95% CI 1.29-5.16). Patients who received S-1 adjuvant treatment showed a significantly poor OS between high GGH/low FPGS and low GGH/high FPGS. Patients without adjuvant treatment showed no significant difference. CONCLUSION: GGH expression was significantly higher in gastric cancer tissue than in adjacent normal mucosa. High GGH and low FPGS expression is a useful independent predictor of poor outcomes in stage II/III gastric cancer patients undergoing postoperative adjuvant chemotherapy with S-1.

RESUMO

BACKGROUND/AIM: Endothelial cell-specific molecule-1 (ESM-1) is a soluble proteoglycan which has important role in various biological events. We investigated the impact of the ESM-1 expression in cancer tissues on outcomes in stage II/III gastric cancer patients who received adjuvant S-1 chemotherapy. PATIENTS AND METHODS: The ESM-1 mRNA expression in cancerous tissues and adjacent normal mucosa from 253 patients was measured. The associations between the ESM-1 gene expression and the survival and clinicopathological features were investigated. RESULTS: A significant association was observed between high ESM-1 expression and undifferentiated adenocarcinoma. The overall survival curve was significantly lower in patients with high ESM-1 expression than in those with low expression (p=0.005). High ESM-1 expression was a significant independent prognosticator (HR=2.291, p=0.007). CONCLUSION: ESM-1 gene expression in cancerous tissues is an important prognosticator in stage II/III gastric cancer patients who received adjuvant S-1 chemotherapy.

RESUMO

BACKGROUND/AIM: The KIAA1199 gene has been associated with cancer-cell proliferation, but its functions remain poorly studied. Here, we examined the clinical significance of the KIAA1199 mRNA levels in locally advanced gastric cancer (GC). Materials and Methods/Results: Using samples from 254 patients with stage II/III GC, we found significantly higher KIAA1199 levels in cancerous tissues compared to adjacent normal mucosa (ANM). There was no significant relationship between KIAA1199 expression and clinical features. Although overall survival rates (OSR) of patients, who underwent surgery did not correlate with KIAA1199 expression, patients who underwent adjuvant chemotherapy with S-1 and had high KIAA1199 levels displayed significantly lower OSR. KIAA1199 knock down (KIAA1199-KD) suppressed proliferation, invasiveness, and sensitivity of GC cells to 5-fluorouracil (5-FU). CONCLUSION: KIAA1199 expression appears to be a promising prognostic marker in patients with locally advanced GC, who underwent postoperative adjuvant chemotherapy with S-1. KIAA1199 may represent a novel target for GC pharmacotherapy.

RESUMO

INTRODUCTION: We retrospectively evaluated the blood coagulation activity using the D-dimer level in the early period after gastrectomy and investigated whether postoperative hypercoagulation affects tumor recurrence and long-term survival in gastric cancer patients. METHODS: The study involved 650 patients who underwent curative resection for gastric cancer at Kanagawa Cancer Center between July 2009 and July 2013. They were divided into a low-D-dimer group (LD group) and high-D-dimer group (HD group) according to the median D-dimer level on postoperative day (POD) 7. The risk factors for overall survival (OS) and relapse-free survival (RFS) were identified. RESULTS: Of the 448 enrolled patients, 218 were classified into the LD group and 230 into the HD group. The 5-year OS rates after surgery were 90.8% and 81.3% in the LD and HD groups, respectively (p < 0.001). The 5-year RFS rates after surgery were 89.9% and 76.1% in the LD and HD groups, respectively (p < 0.001). A high D-dimer level on POD 7 (≥ 4.9 µg/ml) was identified as an independent predictive factor for both the OS (hazard ratio [HR] 1.955, 95% confidence interval [CI] 1.158-3.303, p = 0.012) and RFS (HR 2.182, 95% CI 1.327-3.589, p = 0.002). Furthermore, hematological recurrence was significantly more frequent in the HD group than in the LD group (p = 0.014). CONCLUSION: A high D-dimer level on POD 7 may predict tumor recurrence and the long-term survival in patients who undergo gastrectomy for locally advanced gastric cancer. Patients with an elevated postoperative D-dimer level need careful observation and diagnostic imaging to timely detect tumor recurrence.

RESUMO

Background: The aim of this study was to determine whether or not the short- and long-term outcomes were affected by the age-adjusted Charlson comorbidity index (ACCI) in patients who underwent curative resection for gastric cancer. Methods: The patients were retrospectively selected from among the medical records of consecutive patients who underwent curative gastrectomy with nodal dissection for gastric cancer at Yokohama City University and Kanagawa Cancer Center from January 2000 to August 2015. Results: A total of 2254 patients were eligible for inclusion in the present study. One thousand six hundred fifty-six patients had an ACCI of <6 points (ACCI low group), while 598 had a score of ≥6 points (ACCI high group). The median age (p<0.001) and American Society of Anesthesiologists physical status (ASA-PS) score (p<0.001) of the ACCI high group were higher in comparison to the ACCI low group. The incidence of surgical complications in the ACCI high group was significantly higher than that in the ACCI low group (12.0% vs. 7.2%, p<0.001). Univariate and multivariate analyses demonstrated that an ACCI high classification was a significant risk factor for postoperative complications. In addition, the 5-year OS rates of the ACCI low and ACCI high groups were 85.4% and 74.1%, respectively. The difference was statistically significant (p<0.001). The univariate and multivariate analyses demonstrated that an ACCI high classification was a significant prognostic factor for OS. Conclusions: Our results support that a high ACCI value is an independent risk factor for the short- and long-term outcomes of patients with gastric cancer. To improve the survival of patients with gastric cancer, it is necessary to carefully plan the perioperative care and the surgical strategy according to the ACCI.

RESUMO

BACKGROUND/AIM: The PRKCI gene encodes Protein kinase C iota. The overexpression of protein kinase C iota is associated with poor outcomes in patients with gastric and other cancers, but the role of the PRKCI gene in gastric cancer is not fully understood. Thus, we evaluated the clinical significance of PRKCI gene expression in gastric cancer. MATERIALS AND METHODS: PRKCI mRNA expression levels in cancerous tissues and adjacent normal mucosa from 398 patients with gastric cancer were measured. Relationships between PRKCI gene expression and clinicopathological characteristics and outcomes were examined. RESULTS: Overall survival was lower in patients with a high expression of PRKCI than in those with low expression (p=0.016). No other relationships were observed. A high PRKCI expression was found to be an independent prognostic factor (p=0.036, HR=1.44, 95%CI=1.02-2.02). CONCLUSION: PRKCI gene expression in cancerous tissue might be a useful prognostic factor in patients with gastric cancer after gastrectomy.

RESUMO

INTRODUCTION: We propose a novel technique to close Petersen's defect using barbed sutures and evaluate the safety and usefulness of this technique by assessing postoperative complications and measuring the time required to close Petersen's defect. MATERIALS AND SURGICAL TECHNIQUE: Petersen's defect was closed laparoscopically with running non-absorbable barbed sutures (V-loc®) after a nodal dissection and reconstruction procedure. First, the transverse colon was elevated cranially, making the dorsal side of the transverse mesocolon a flattened surface. The intersection of the transverse mesocolon and Roux limb mesentery was then identified, and closure was started from this point. We continued to sew the transverse mesocolon and Roux limb mesentery toward the transverse colon with a running suture. At the end of suturing, we placed one or two stitches in the fatty appendices of the transverse colon and cut the free tail of thread as short as possible. DISCUSSION: We investigated postoperative complications and measured the time required to close Petersen's defect in 64 patients who underwent this technique. The results showed that this closure technique could be performed promptly and safely regardless of the patient, surgical procedure, and the experience of the operator.

RESUMO

Aims: We previously demonstrated that a loss of lean body mass loss at one month after gastrectomy was an independent risk factor for the continuation of adjuvant chemotherapy with S-1. However, it is unclear whether or not lean body mass loss after gastrectomy leads to a poor survival through poor compliance to adjuvant chemotherapy with S-1. Methods: The recurrence free survival (RFS) overall survival (OS) and were examined in 115 patients who underwent curative gastrectomy and were pathologically diagnosed with stage II or III gastric cancer and who received postoperative adjuvant chemotherapy with S-1 between May 2011 and September 2016. Results: The median follow-up period was 40.6 months. The RFS rates at 5 years after surgery were 57.8% in the lean body mass loss ≥5% group and 73.5% in the lean body mass loss <5% group. The univariate and multivariate analyses for the disease free survival (RFS) demonstrated that a lean body mass loss >5% was a significant risk factor. The OS rates at 5 years after surgery were 72.0% in the lean body mass loss ≥5% group and 77.3% in the lean body mass loss <5% group. The OS was slightly worse in the lean body mass loss ≥5% group than in the lean body mass loss <5% group (p=0.2062). Conclusions: The lean body mass loss at one month, which is closely associated with poor S-1 compliance, was an important risk factor for the RFS. A prospective cohort study is necessary to confirm whether or not the lean body mass loss affects the gastric cancer survival.

RESUMO

A 63-year-old man was admitted to our hospital for examination and treatment of a pancreatic head tumor detected at a nearby hospital. After CT, EUS-FNA, and PET-CT, he was diagnosed with unresectable pancreatic cancer with liver metastasis. After 9 courses of gemcitabine and nab-paclitaxel therapy, the primary tumor was dramatically reduced in size and the liver metastasis had disappeared. He underwent subtotal stomach-preserving pancreaticoduodenectomy. The postoperative diagnosis according to the General Rules of the Study of Pancreatic Cancer(7th edition)was Ph, TS1(15mm), adenosquamous carcinoma, ypT3, ypRP1, ypPL1, R0, ypN0(0/29), M0, CY0, ypStage ⅡA. The histological response was Grade 2. The patient remains alive without recurrence 5 months after surgical resection.

RESUMO

BACKGROUND: This study investigated the impact of postoperative C-reactive protein (CRP) level on survival in patients with esophageal cancer who received perioperative steroid therapy and enhanced recovery after surgery (ERAS) care. PATIENTS AND METHODS: Overall, 115 patients were retrospectively reviewed. The patients were classified into those with a high CRP level (≥4.0 mg/dl) on postoperative day 4 and those with low CRP level (<4.0 mg/dl). The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. RESULTS: The OS and RFS rates at 5 years after surgery were significantly low in patients with high CRP level on postoperative day 4. The multivariate analysis demonstrated that high CRP level on postoperative day 4 was a significant independent risk factor for OS and RFS. CONCLUSION: The present results suggest that the postoperative CRP level can be a prognosticator in patients with esophageal cancer who have received perioperative steroid therapy and ERAS care.

RESUMO

BACKGROUND: Body weight, especially lean body mass, significantly decreases after gastrectomy. Postoperative surgical complications are a major risk factor for changes in body weight and body composition after gastrectomy. However, the influence of postoperative surgical complications after gastrectomy on body weight and body composition changes remains unclear. PATIENTS AND METHODS: This retrospective study examined patients who underwent curative surgery for gastric cancer between May 2010 and February 2017. Their body weight and composition were evaluated by a bioelectrical impedance analyzer within 1 week before surgery, and at 1 week, 1 month and 3 months after surgery. Patients were classified as those with surgical complications and those without. RESULTS: Eight hundred and eighty-eight patients (156 in the group with complications and 732 in the group without) were entered in the present study. When comparing the two groups, the patients' background and surgical factors significantly differed, while the pathological findings were similar. The body weight losses at 1 week, 1 month, and 3 months after surgery were 3.8%, 7.0%, and 10.4%, respectively, in those with complications, and 3.3%, 5.6%, and 6.8%, respectively, in the group without, with p-values of 0.001, 0.002, and 0.001, respectively. The corresponding lean body mass losses were 3.7%, 6.5%, and 6.8%, and 3.2%, 4.2%, and 3.5%, respectively, with p-values of 0.001, 0.001, and 0.001, respectively. CONCLUSION: Decreases in body weight and lean body mass after gastrectomy were more serious in the patients with surgical complications than in those without. To maintain body weight and lean body mass in patients with surgical complications, additional care or treatments are needed.

RESUMO

BACKGROUND: Postoperative adjuvant chemotherapy with S-1 for 1 year (corresponding to eight courses) is standard care for stage II gastric cancer. Whether the duration of S-1 could be shortened to 6 months (corresponding to four courses) without worsening survival is unclear. The aim of this study was to investigate the non-inferiority of four courses of S-1 compared with eight courses of S-1 for patients with stage II gastric cancer. METHODS: We did a phase 3, open-label, randomised controlled, non-inferiority trial at 59 hospitals in Japan. Patients aged 20-80 years with stage II adenocarcinoma of the stomach were randomly assigned (1:1) to eight courses or four courses of S-1. Randomisation was done by the Japan Clinical Oncology Group Data Center website, using a minimisation method with a random component using institution, stage (IIA vs IIB), age (<70 years vs ≥70 years), and mode of operation (open gastrectomy with bursectomy vs open gastrectomy without bursectomy vs laparoscopic gastrectomy) as adjustment factors. One course was 80 mg/day per m2 of S-1 administered for 4 weeks followed by a rest for 2 weeks. The primary endpoint was relapse-free survival, analysed by intention to treat, with a non-inferiority margin for the hazard ratio (HR) set at 1·37. This study is registered at UMIN-Clinical Trial Registry, number UMIN000007306. FINDINGS: Between Feb 16, 2012, and March 19, 2017, 590 patients were enrolled (295 per group). 528 (89%) patients were analysed at the first planned interim analysis in March, 2017, at which time the point estimate of HR for the four-course group compared with the eight-course group was 2·52 (95% CI 1·11-5·77), which exceeded 1·37 and met the prespecified criteria for early termination. Predictive probability for showing non-inferiority at the final analysis was calculated to be 2·9%. The study was stopped for futility. Updated 3-year relapse-free survival analysed in May, 2017, was 93·1% (95% CI 87·8-96·1) for the eight-course group and 89·8% (84·2-93·5) for the four-course group (HR 1·84, 95% CI 0·93-3·63). The most common grade 3-4 adverse event was neutropenia, observed in 46 (16%) patients in the eight-course group and 51 (17%) patients in the four-course group. INTERPRETATION: S-1 for 1 year should remain as standard adjuvant chemotherapy for stage II gastric cancer.

RESUMO

BACKGROUND: Several efforts have been made to alleviate harms and symptoms after gastrectomy for gastric cancer. We previously conducted a randomized controlled trial (CCOG1101) to compare quality of life (QOL) and nutritional status between Roux-en-Y (RY) and aboral pouch (AP) reconstructions for up to 1 year after total gastrectomy. However, long-term outcomes after AP reconstruction remain unclear. METHODS: A prospective multicenter observational study was conducted to compare QOL, body composition, and nutritional indicators between the RY and AP reconstructions at 5 years after surgery among patients who were enrolled in the CCOG1101 trial. QOL was assessed by the PGSAS-37 questionnaires as well as the EORTC QLQ-C30 and STO22. RESULTS: Sixty patients (31 for RY and 29 for AP) were recruited for analysis. There were no significant differences in baseline and perioperative characteristics between the two groups. No significant differences were found in the EORTC QLQ-C30 global health status and functional scales. Regarding symptom scales in the QLQ-C30 and STO22, a more favorable score for the diarrhea scale was observed in the AP group. Diarrhea was also the only item in the PGSAS-37 questionnaires in which significant benefit of AP was observed. Body weight and lean body mass continued to decrease throughout the postoperative 5 years in both groups. None of the conventional nutritional indicators using the serum samples showed significant difference between the two groups. CONCLUSIONS: Long-term observation suggested little benefit of AP reconstruction after total gastrectomy other than in alleviating diarrhea.

RESUMO

BACKGROUND: Laparoscopy-assisted distal gastrectomy (LADG) has an advantage of earlier recovery after surgery due to having lower invasiveness and wound pain than open distal gastrectomy (ODG). However, whether the same enhanced recovery after surgery (ERAS) program for LADG is equally feasible and safe for ODG remains unclear. METHODS: We retrospectively extracted the clinical data of the patients enrolled in JCOG0912 from the medical record system of our hospital and compared the treatment process and short-term surgical outcomes between LADG and ODG. Our ERAS program consisted of 13 elements (4 preoperative, 4 intraoperative, and 5 postoperative elements). The morbidity was defined as complications of grade 2 or more. RESULTS: One hundred and sixty-three patients were entered from our hospital and randomized to undergo ODG (82 patients) or LADG (81 patients). The patient's backgrounds, surgical outcomes, and pathological outcomes were similar between the ODG and LADG groups. The rate of completing the clinical pathway was 95.1% in both groups, and the rates of completing each ERAS element were similar. However, the additional use of acetaminophen was significantly more frequent in the ODG group than in the LADG group (18.3% vs. 6.2%, p = 0.03). The median hospital stay after surgery was 9 days in both groups. Morbidity, defined as Clavien-Dindo classification > grade 2, was observed in 6.1% of the ODG group and 11.1% of the LADG group. No mortality occurred in either group. CONCLUSION: This study showed that the regimen of perioperative care performed by the ERAS program for LADG was equally feasible and safe for ODG with additional pain control. Less pain observed in LADG was not so apparent advantage for completion and safety of ERAS care.

RESUMO

BACKGROUND: Body weight, especially lean body mass, significantly decreases after gastrectomy for gastric cancer due to surgical invasion, reduced food intake, and reduced mobility, which can reduce the quality of life and induce associated toxicity or reduce compliance with adjuvant chemotherapy. Such risks can be particularly high in elderly patients with gastric cancer. However, whether or not changes in the weight and body composition differ between elderly and non-elderly patients remains unclear. PATIENTS AND METHODS: This retrospective study examined patients who underwent curative surgery for gastric cancer between May 2010 and February 2017. Body weight and composition were evaluated by a bioelectrical impedance analyzer within 1 week before surgery, at 1 week after surgery, and at 1 and at 3 months after surgery. Patients were classified as elderly (≥80 years) or non-elderly (<80 years). RESULTS: Eight-hundred and eighty-eight patients (84 elderly and 804 non-elderly) were entered into the present study. Patient background, surgical and clinicopathological factors, and surgical complications did not significantly differ between the two groups. Body weight loss at 1 week, and at 1 and 3 months after surgery, defined as the decrease from the preoperative value, were -2.8%, -6.5%, and -9.0%, respectively, in the elderly and -3.5%, -6.0%, and -8.1%, respectively, in the non-elderly patients (p=0.111, 0.125, and 0.153, respectively). The corresponding losses of lean body mass were -2.6%, -6.0%, and -6.4%, respectively, in the elderly and -3.5%, -4.9%, and -4.7%, respectively, in the non-elderly patients, with p-values of 0.056, 0.036, and 0.029, respectively. CONCLUSION: Decreases in lean body mass after gastrectomy were greater in elderly than in non-elderly patients. In order to maintain lean body mass among elderly patients, additional care and treatments are needed.
