Risk factors of "loss of independence" in elderly patients who received gastrectomy for gastric cancer.

OBJECTIVE: The aim of this study was to clarify the risk of loss of independence (LOI) following gastrectomy in elderly patients with gastric cancer (GC). METHODS: In this prospective study, frailty was assessed preoperatively by a frailty index (FI) in 243 patients aged ≥ 65 years who underwent gastrectomy for GC between August 2016 and December 2020. Patients were assigned into two groups (high FI vs. low FI) to investigate frailty and the risk of LOI after gastrectomy for GC. RESULTS: Overall and minor (Clavien-Dindo classification [CD] 1, 2) complication rates were significantly higher in the high FI group, but the two groups had similar rates of major (CD ≥ 3) complications. The frequency of pneumonia was significantly higher in the high FI group. In univariate and multivariate analyses for LOI after surgery, high FI, older age (≥ 75 years), and major (CD ≥ 3) complications were independent risk factors. A risk score assigning 1 point for each of these variables was useful in predicting postoperative LOI (LOI: score 0, 7.4%; score 1, 18.2%; score 2, 43.9%; score 3, 100%; area under the curve [AUC] = 0.765.) CONCLUSIONS: LOI after gastrectomy was independently associated with high FI, older age (≥ 75 years), and major (CD ≥ 3) complications. A simple risk score assigning points for these factors was an accurate predictor of postoperative LOI. We propose that frailty screening should be applied for all elderly GC patients before surgery.

[Surgical Technique for Mesorectal Division in the Robotic Anterior Resection for Rectal Cancer].

Since April 2018, robot-assisted rectal resection has been approved as an insurance medical treatment, and robot- assisted rectal resection is rapidly becoming widespread. Even in robot-assisted laparoscopic surgery, mesorectal division is difficult in a narrow pelvic cavity. At the beginning of the operation, Vessel Sealer ExtendTM(price 89,250 yen)was used, but as the procedure became stable, the mesorectal division was started with bipolar forceps and monopolar scissors. The purpose of this study was to investigate the mesorectal division time and postoperative complications associated with changes in the procedure. 36 patients who underwent robot-assisted anterior resection for rectal cancer by the same surgeon from January 2019 to December 2021. We compared mesorectal division time and postoperative complication. Median operation time were 267 minutes, median console time were 132 minutes. There were no complications such as intestinal obstruction or anastomotic leakage. There was no difference in mesorectal division time time between Vessel Sealer groups and Scissors groups(14 min 55 sec vs 16 min 5 sec). The mesorectal division with bipolar forceps and monopolar scissors could be performed without extending the operation time, and could be performed with cost-benefit and safely.

The Surgical Apgar Score Predicts Postoperative Complications in Elderly Patients After Surgery for Colorectal Cancer.

OBJECTIVE: The surgical Apgar score (SAS) has been validated as a risk assessment tool for postoperative complications. However, the utility of the SAS in elderly patients with colorectal cancer remains unclear. In this study, we evaluated the utility of the SAS for predicting the severe complications in elderly patients with colorectal cancer. METHODS: We retrospectively analyzed 295 patients underwent radical surgery for colorectal cancer in elderly patients ≥75 years old. The SAS was calculated based on 3 intraoperative parameters: estimated blood loss (EBL), lowest mean arterial pressure, and lowest heart rate. Severe complications were defined as Clavien-Dindo classification grade ≥ IIIa. We divided all patients into 2 groups according to with or without severe complications. The optimal cut-off value of SAS for severe complications has been determined by receiver operator characteristic curve. Predictors for severe complications were analyzed by logistic regression modeling. RESULTS: Severe complications were observed in 57 patients (19.3%). Male, rectal cancer, operation time (>240 minutes), EBL (≥120 mL), and a low SAS (≤6) were significantly associated with severe complications in univariate analysis. A multivariate analysis revealed that male, rectal cancer, and a low SAS (≤6) were independent predictors for severe complications. CONCLUSIONS: A low SAS (≤6) was associated with severe complications after colorectal cancer surgery in elderly patients. The SAS is a valuable predictor for severe complications in elderly patients with colorectal cancer.

Comparison of Short-Term Surgical Outcomes of Two Types of Robotic Gastrectomy for Gastric Cancer: Ultrasonic Shears Method Versus the Maryland Bipolar Forceps Method.

BACKGROUND: This study investigated the impact and short-term surgical outcomes of two different main energy devices for robotic gastrectomy for gastric cancer. The outcomes of robotic gastrectomy with ultrasonic shears and those of robotic gastrectomy with conventional forceps were compared. METHODS: We retrospectively evaluated 171 patients who underwent robotic distal gastrectomy or total gastrectomy for gastric cancer. We classified patients into the ultrasonic shears (US) and Maryland bipolar (MB) forceps groups according to the main energy device used for robotic gastrectomy. RESULTS: We extracted 58 patients from the US group and 58 patients from the MB forceps groups using propensity score matching. The total console time (310 min [interquartile range (IQR), 253-369 min] and 332 min, [IQR, 294-429 min]; p = 0.022) and the console time to gastrectomy (222 min [IQR, 177-266 min] and 247 min [IQR, 208-321 min]; p = 0.004) were significantly shorter in the US group than in the MB forceps group. Less blood loss occurred in the US group than in the MB forceps group (20 mL [IQR, 10-40 mL] and 30 mL [IQR, 16-80 mL]; p = 0.014). The postoperative complication rate and postoperative hospital stay length were similar between groups. A multivariate multiple linear regression analysis demonstrated that the use of an ultrasonically activated device was one an independent factor that reduced the operative time of robotic gastrectomy. CONCLUSION: Using ultrasonic shears as the main energy device may contribute to better surgical outcomes after robotic gastrectomy for gastric cancer.

Jejunal Mesentery Preservation Reduces Leakage at Esophagojejunostomy After Minimally Invasive Total Gastrectomy for Gastric Cancer: a Propensity Score-Matched Cohort Study.

PURPOSE: The mesentery of the jejunum (MJ) of the Roux limb is conventionally divided when Roux-en-Y reconstruction is performed after total gastrectomy for gastric cancer (GC). However, the impact of dividing or preserving the MJ on anastomotic leakage (AL) at the esophagojejunostomy (EJS) site after minimally invasive total gastrectomy for GC is unclear. METHODS: This retrospective cohort study enrolled 226 patients with GC who underwent EJS after laparoscopic or robotic total gastrectomy, including preservation of the MJ (n = 87) and division of the MJ (n = 137). The prevalence of anastomotic complications at the EJS and short-term outcomes were compared between groups using propensity score (PS) matching. RESULTS: After PS matching, 69 patients were selected for the preserving and dividing MJ groups. There were no significant intergroup differences in patient backgrounds, including oncological stage, body mass index, and gender ratio. After PS matching, overall and severe complications after surgery were compared between the preserving and dividing MJ groups (21.7% vs. 27.5%, p = 0.554 and 8.7% vs. 13.8%, p = 0.137, respectively). However, the rate of AL at the EJS was significantly lower in the preserving than that in the dividing MJ group (1.4% vs. 13.0%, p = 0.017). In addition, the median postoperative hospital stay was significantly shorter in the preserving than that in the dividing MJ group (13.0 days vs. 16.0 days, p = 0.005). CONCLUSIONS: Preserving the MJ significantly reduced AL at the EJS after minimally invasive total gastrectomy for GC.

[Locally Advanced Pancreatic Cancer Treated with Two-Staged Pancreaticoduodenectomy after Laparoscopic Median Arcuate Ligament Section-A Case Report].

A 76-year-old male was diagnosed as locally advanced pancreatic cancer because abdominal CT scan revealed a pancreatic head tumor with involvement of the proper hepatic artery. Gemcitabine plus nab-paclitaxel was initiated, but was discontinued because interstitial pneumonia was occurred. The treatment was switched to S-1 therapy and achieved stable disease for 22 months. Therefore, conversion surgery was scheduled. Because stenosis of the celiac artery origin due to median arcuate ligament(MAL)compression and dilatation of pancreatoduodenal artery arcade were observed, laparoscopic MAL section was performed. The patient was discharged on postoperative day 5 without complications. Postoperative CT scan revealed no stenosis of the celiac artery origin and disappearance of dilatation of pancreatoduodenal artery arcade. On postoperative day 14, subtotal stomach-preserving pancreaticoduodenectomy(PD)with portal vein resection was performed. The patient was discharged on postoperative day 19 without complications. Two-staged PD after MAL section make possible to evaluate blood flow accurately and select an appropriate operative method. Laparoscopic MAL section is minimally invasive and may be useful for two-staged PD in patients with celiac axis stenosis.

Less Severe Intra-Abdominal Infections in Robotic Surgery for Gastric Cancer Compared with Conventional Laparoscopic Surgery: A Propensity Score-matched Analysis.

BACKGROUND: The impact of robotic gastrectomy (RG) for gastric cancer (GC) on the incidence of postoperative complication is debatable and unclear. METHODS: This study enrolled 200 patients with GC who were surgically treated and consisted of 100 RG and 100 laparoscopic gastrectomy (LG) cases using an ultrasonic scalpel. The short-term outcomes were compared between the two groups. These outcomes were compared using a 1:1 propensity score (PS)-matching analysis. RESULTS: After PS matching, 76 cases in each group were well matched. Mean surgical time was significantly longer in the RG group than in the LG group (393 vs. 342 min, p < 0.005), whereas mean blood loss during surgery was significantly lower in the RG group than in the LG group (30.1 vs. 50.1 mL, p = 0.023). The median number of surgeons who attend the main part of the surgery was significantly less in the RG group than in the LG group (2.0 vs. 3.0, p = 0.01). The rate of severe intra-abdominal infectious complication was significantly lower in the RG group than in the LG group (0% vs. 9.2%, p = 0.014). The duration from surgery to adjuvant chemotherapy was significantly shorter in the RG group than in the LG group (29.6 ± 11.0 vs. 45.2 ± 27.8 days, p = 0.046). CONCLUSIONS: RG using an ultrasonic scalpel may be a viable alternative to LG because of the improvement in the rate of postoperative intra-abdominal infectious complications after curative surgery for GC.

[Impact of Sarcopenia on Patients with Advanced Gastric Cancer Who Underwent Surgery].

This study aimed to investigate the short- and long-term outcomes in patients with sarcopenia who underwent surgery for advanced gastric cancer. We included 76 patients with pStage Ⅱ or Ⅲ gastric cancer who underwent gastrectomy between January 2017 and June 2021. Patients with pT3N0 cancer were excluded. Using the Asian Working Group for Sarcopenia( AWGS)2019 criteria, the patients were divided into the sarcopenia group(S group)and the non-sarcopenia group (NS group). The surgical outcomes, effects on postoperative adjuvant chemotherapy, and prognosis of the 2 groups were evaluated and compared. No significant differences were observed in the operative time, blood loss, postoperative hospital stays, or incidence of postoperative complications with a grade higher than Clavien-Dindo Grade Ⅱ. The number of patients who received postoperative adjuvant chemotherapy was 5(26.3%)in the S group and 38(66.7%)in the NS group which was significantly lower in the S group(p=0.003). The 3-year overall survival rate was 45.7% in the S group and 71.0% in the NS group(p=0.302). There was no significant difference but survival rate was lower in the S group. The results suggest that postoperative adjuvant chemotherapy is not always available for patients with advanced gastric cancer, and that may worsen the prognosis.

[A Case of Robotic Surgery for Local and Peritoneal Recurrence of Colorectal Cancer].

A 35-year-old women with sigmoid cancer(pT4aN1aM0, pStage Ⅲb)underwent laparoscopic sigmoidectomy. She had 8 courses of CapeOX for adjuvant chemotherapy, but follow up CT scan 1 year after the operation detected intraabdominal nodules in anastomotic site and in left lower quadrant of abdomen. After 10 courses of IRIS plus bevacizumab, the both intraabdominal nodules decreased in size. Robot assisted laparoscopic lower anterior resection and laparoscopic disseminated nodule resection were performed. The patient had no postoperative complications and the postoperative course was good. She remains alive without recurrence at 6 months after the second operation.

[A Case of pStage IB Gastric Cancer Relapsed on Both Pleura and Peritoneum Eight Year after Radical Gastrectomy].

An 86-year-old man presented with upper abdominal pain and was diagnosed with type 0-Ⅲ gastric cancer located at the posterior wall of the upper stomach by upper gastrointestinal endoscopy. Laparoscopic total gastrectomy(D1+)was performed for gastric cancer of cStage Ⅰ. As final pathological diagnosis was pT2N0(0/27)M0H0P0CY0, pStage ⅠB, adjuvant chemotherapy was not administrated. The patient has been alive with no recurrence for 5 years after surgery. 8 years and 1 month after procedure, he visited our hospital with chief complaint of abdominal distention and anorexia. Chest and abdominal CT showed pleural fluid and ascites, but PET-CT could not detect any sites of recurrence. Cytopathology and cell blocks by immunohistochemical staining of ascites proved recurrence of previous gastric cancer. Any treatment was rejected, and the patient died 3 months after recurrence and 8 years and 4 months after gastrectomy. Late recurrence on both pleura and peritoneum of gastric cancer is very rare. We report a case of pStage ⅠB gastric cancer relapsed on both pleura and peritoneum 8 year after radical gastrectomy.

[A Case of Recurrent Gastric Cancer of Multiple Organ Metastasis with Long-Term Survival Due to Multimodal Treatment].

A 67-year-old man was introduced to examine for abnormal findings in physical examination. Upper gastrointestinal endoscopy detected the 3 lesions and diagnosed multiple gastric cancers with biopsy. Laparoscopic total gastrectomy was performed and final pathological diagnosis was pT2N1M0, pStage ⅡA with HER2 positive(3+). Adjuvant chemotherapy was not administrated. CT findings 6 months after procedure showed 2 liver metastases(S6, S7)and laparoscopic partial liver resection was performed. Pathological findings proved the metastasis of previous gastric cancer. Although adjuvant chemotherapy of S-1 was started 2 months after hepatectomy, CT findings showed second recurrences in liver and right adrenal gland. Chemotherapy was changed to S-1 plus cisplatin(SP)plus trastuzumab. AS these recurrence sites and ascites could not be detected by CT after 6 courses, therapeutic effect was judged as clinical CR(cCR)and SP plus trastuzumab was stopped due to side effect. Since then, regular follow-up CT showed preservation of status of cCR without chemotherapy and he has been alive without recurrence for 8 years and 9 months after gastrectomy. We report a case of recurrent gastric cancer of multiple organ metastasis with long-term survival due to multimodal treatment.

Depletion of skeletal muscle mass adversely affects long-term outcomes for men undergoing gastrectomy for gastric cancer.

BACKGROUND: Although low skeletal muscle mass has an adverse impact on the treatment outcomes of cancer patients, whether the relationship between preoperative skeletal muscle mass and gastrectomy outcomes in gastric cancer (GC) differs between men and women is unclear. The study aimed to clarify this relationship based on gender. METHODS: Between January 2007 and December 2015, 1054 patients who underwent gastrectomy for GC at Osaka City General Hospital were enrolled in this study. We evaluated sarcopenia by the skeletal muscle index (SMI), which was measured by computed tomography (CT) using areas of muscle in the third lumbar vertebral body (L3). Male and female patients were each divided into two groups (low skeletal muscle and high skeletal muscle). RESULTS: The SMI emerged as an independent predictor of 5-year overall survival (OS) in male GC patients (Hazard ratio 2.51; 95% confidence interval (CI) 1.73-3.63, p < 0.001) based on multivariate analysis. However, this index was not an independent predictive determinant of 5-year cancer-specific survival (CSS). The SMI was not an independent predictor of either OS or CSS in female GC patients. The incidence of leakage and major complication (Clavien Dindo grade ≧ 3) did not differ significantly across groups. CONCLUSIONS: Preoperative skeletal muscle mass is a valuable prognostic predictor of OS in male GC patients.

[A Case of Double Colorectal Cancer Diagnosed by Preoperative CT Colonography].

A 66‒year‒old man was admitted to our hospital because of anemia and a positive fecal occult blood test in the medical examination. Colonoscopy revealed a type 2 advanced sigmoid colon cancer with circular stenosis. Computed tomography (CT)colonography was performed to examine the oral colon. The apple core signs were found both in the sigmoid and transverse colon. We diagnosed a double colon cancer and performed a laparoscopic left hemicolectomy and sigmoidectomy. The tumor was histopathologically diagnosed as a multiple cancer including a transverse and a sigmoid colon cancer. Although evaluations of the intestine for colon cancer with stenosis are performed by enema examination or endoscopic examination after colon stent placement, both examinations are invasive. CT colonography is considered to be a minimally invasive and an effective preoperative examination for colorectal cancer with stenosis.

Multiple stage IV colorectal cancers in a patient who received multidisciplinary treatment, including chemotherapy and Japanese Kampo medicine: A case report.

FOLFOXIRI (fluorouracil, leucovorin, oxaliplatin, and irinotecan) plus bevacizumab is the preferred first-line treatment for right-sided metastatic colorectal cancer with RAS mutation. However, severe adverse events are common in Japanese patients. We report the successful management of multiple stage IV colorectal cancers in a patient who received multidisciplinary treatment, including chemotherapy and Japanese Kampo medicine. A 68-year-old man presented with epigastralgia and appetite loss and was diagnosed with multiple stage IV colorectal cancers. Colonoscopy identified type II tumors in the ascending colon, sigmoid colon, and upper rectum. Histopathological examination of a biopsy specimen revealed well- to moderately differentiated tubular adenocarcinoma. Enhanced computed tomography of the thorax and abdomen showed multiple pulmonary nodules and para-aortic lymph node swelling. Laparoscopic loop-ileostomy was performed to avoid bowel obstruction due to severe stenosis of ascending colon cancer. Intraoperative observation revealed two white nodules suggestive of metastasis in the lateral area of the liver. Therefore, we diagnosed multiple stage IV colorectal cancers with multiple metastases (lung, liver, and distant lymph nodes). His postoperative course was uneventful, and chemotherapy was started. Since the cancer cells harbored a RAS mutation, he received FOLFOXIRI plus bevacizumab. Japanese Kampo medicine consisting of Hangeshashinto and Juzen-taiho-to, to prevent diarrhea and fatigue, was administered daily. After 12 courses of chemotherapy, though circumferential stenosis still existed in the ascending colon, the tumors in the sigmoid colon and upper rectum were unclear. Enhanced computed tomography showed shrinkage of the pulmonary nodules and para-aortic lymph node; therefore, laparoscopic-assisted ileocecal resection was performed. The postoperative histopathological examination revealed moderately differentiated adenocarcinoma. The patient recovered uneventfully, and Kampo medicine consisting of Ninjin'yoeito was administered for postoperative weakness. Administration of adjuvant chemotherapy in this patient led to a near complete response that has been maintained without recurrence for 2 years and 8 months without reduced quality of life.

Impact of chronic kidney disease on the short- and long-term outcomes of laparoscopic gastrectomy for gastric cancer patients.

BACKGROUNDS: This study was undertaken to investigate the impact of coexisting chronic kidney disease (CKD) on short- and long-term outcomes of laparoscopic gastrectomy in patients with gastric cancer (GC). METHODS: We reviewed the data of 798 patients treated for GC by laparoscopic gastrectomy. All procedures took place between January 2010 and December 2017. Patients were divided into three groups according to their estimated glomerular filtration rate (eGFR): severe CKD group, 44 patients with eGFR < 45 mL/min/1.73 m2; moderate CKD group, 117 patients with 45 ≤ eGFR < 60; control group, 637 patients with eGFR ≥ 60. RESULTS: Based on multivariate analysis, severe CKD (eGFR < 45) emerged as an independent predictor of anastomotic leak (Hazard ratio 4.63, 95% confidence interval [CI] 1.62-11.54). The 5-year overall survival (OS) rates by group were 46.3% (severe CKD), 76.6% (moderate CKD), and 81.5% (control). Multivariate analysis likewise identified severe CKD (eGFR < 45) as an independent correlate of poor 5-year OS. The 5-year cancer-specific survival (CSS) rates did not differ significantly by group. CONCLUSIONS: An eGFR value less than 45 mL/min/1.73 m2 is a useful factor for predicting both anastomotic leak and 5-year OS in GC patients undergoing laparoscopic gastrectomy. Clinical care to improve eGFR should be reinforced before and after gastrectomy for GC patients with severe CKD.

[Prognostic Analysis of Colorectal Cancer Patients by the Controlling Nutritional Status(CONUT)Score].

We examined the controlling nutritional status(CONUT)score and the long-term prognosis of colorectal cancer surgery cases. We retrospectively examined the prognosis of colorectal cancer patients who underwent surgery between January 2013 and December 2015. We targeted 449 patients who were able to calculate the CONUT score. A total of 266 patients (59.2%)had normal nutritional status(1 or less)and 183 patients(40.8%)had mildly poor or worse nutritional status (2 or more). The CONUT score was calculated through preoperative blood tests. The relationship between the CONUT score and overall survival was examined in the low and high groups. Overall survival was significantly shorter in the high group but relapse-free survival did not differ significantly between the 2 groups. There was no difference in cancer-specific survival between the 2 groups, but the survival time due to death from other diseases was significantly shorter in the high group. The CONUT score obtained from preoperative blood sampling suggested that the overall survival time was short in the malnourished group, and that it could be used as an index of prognosis due to death from other diseases.

[Short-Term Clinical Outcome of Robotic Surgery for Advanced Rectal Cancer after Neoadjuvant Therapy].

We examined 14 cases who underwent robotic rectal resection with neoadjuvant chemotherapy(NAC)or neoadjuvant chemoradiation therapy(NACRT)for local advanced rectal cancer in our hospital from 2018 June to 2020 December. Two patients underwent NACRT, 12 patients underwent NAC. Sex was 10 males and 4 females. The median age was 66. The surgical procedure was ISR 2 cases, LAR 8 cases, APR 4 cases. The median operation time was 397 minutes and the median blood loss was 73 mL. The histological response grade were Grade 3: 1 case, 2: 7 cases, 1b: 3 cases, and 1a: 3 cases. Surgical margin was negative in all cases. Postoperative complications(≥Clavien-Dindo Grade Ⅲ)required reoperation due to intestinal obstruction in 1 case. Urinary dysfunction was nothing in all cases. Although long-term results such as prognosis and function preservation need to be examined, short-term results of robot-assisted rectal resection after NAC or NACRT were generally good.

[A Case of Robot Assisted Low Anterior Resection for a Patient with Persistent Descending Mesocolon].

Persistent descending mesocolon(PDM)is caused by absence of fusion of the descending colon to the retroperitoneum. A 67-year-old man with bloody stools was diagnosed with rectal cancer on colonoscopy. A computed tomography showed a medial displacement of his descending colon. The preoperative clinical diagnosis was rectal cancer with PDM, and robot assisted low anterior resection was performed. We found that the left-sided colon was shifted to the midline and adhered the cecum and the mesentery of small intestine. Robot assisted surgery enables surgery with the precise adhesiotomy in a stable field. PDM is a relatively rare anatomic abnormality. Character of PDM is adhesion between the left-sided colon and other organs and radially branch from the inferior mesenteric artery. It is important to understand the anatomical characteristics of PDM and to improve on existing surgical procedures to ensure safe robot assisted surgery these patients.

[A Case of Advanced Gastric Cancer-Recurrence of Skin Metastasis Nine Years after Surgery and Rectal Stenosis Due to Peritoneal Dissemination Ten Years Later].

A 70-year-old man previously underwent laparoscopic total gastrectomy for gastric cancer in 2010 and pathological diagnoses were pT4a, pN3, M0, pStage ⅢC. The postoperative adjuvant chemotherapy was interrupted due to nausea, but the patient had no apparent recurrence within 5 years after gastrectomy. In 2019, a swelling appeared from the left inguinal region to the scrotum, and MRI scan showed subcutaneous edematous changes in the same region. Biopsy showed adenocarcinoma and we diagnosed a recurrence of gastric cancer with skin metastasis. In November 2020, the patient complained of defecation disorder, and CT scan showed a circumferential wall thickening with contrast effect in the rectum. Although colonoscopy revealed rectal stenosis, biopsy specimen showed no malignant findings. We suspected rectal stenosis due to peritoneal dissemination of gastric cancer and performed a colostomy. Intraoperative findings showed that the rectal wall was remarkably thickened with serosal erythema. Adenocarcinoma cells were found from the cytology of ascites. The patient was treated with nab-paclitaxel plus ramucirumab, then treated with nivolumab after failure of first-line therapy.

[Short- and Long-Term Surgical Outcomes for Patients with Colorectal Cancer Aged 80 Years or Older].

This study aimed to assess short-term and long-term outcomes and to identify the factors that affect outcomes for patients with colorectal cancer aged 80 years or older. Two hundred patients with colorectal cancer who were underwent resection of the primary tumor between January 2013 and December 2018 were enrolled. Short-term outcomes of elderly patients with poor PS and of those who take antithrombotic agents and of those who were underwent open surgery were poor. Long-term outcomes of elderly patients with high GNRI and of those who were underwent D3 lymph nodes dissection were better. Laparoscopic surgery with D3 lymph nodes dissection for elderly patients who were more than 80 years old should be useful to improve short- and long-term outcomes. GNRI might be a prognostic predictive factor for patients with colorectal cancer aged 80 years or older.
