Geriatric Nutritional Risk Index Is an Independent Prognostic Factor for Patients With Esophageal Cancer Who Receive Curative Treatment.

BACKGROUND/AIM: The perioperative nutritional status has recently been reported to influence the prognosis of various types of cancer. We investigated the relationship between the Geriatric Nutritional Risk Index (GNRI) and overall survival (OS) and recurrence-free survival (RFS) in patients with esophageal cancer who received radical and adjuvant therapy. PATIENTS AND METHODS: Patients who underwent radical resection for esophageal cancer at our hospital (n=187) were included. Background characteristics, surgical factors, and OS were examined retrospectively. The GNRI was calculated using preoperative values, with GNRI <98 classified as low-GNRI. RESULTS: Seventy-five and 112 patients were classified into the GNRI-low and -high groups, respectively. The 3- and 5-year OS rates were 75.7% and 66.7%, respectively, in the GNRI-high group and 43.2% and 36.7% in the GNRI-low group; the difference was statistically significant (p<0.001). In the univariate and multivariate analyses, low-GNRI was selected as a risk factor for OS. The hazard ratio for low-GNRI was 2.184 (95% confidence interval=1.361-3.508, p=0.001). The 5-year RFS rate in the high- and low-GNRI groups was 54.6% and 25.0%, respectively (p=0.001). In the univariate and multivariate analyses, low-GNRI was a risk factor for RFS. The hazard ratio for low-GNRI was 1.704 (95%CI=1.121-2.590, p=0.013). Regarding the type of recurrence, lymph node recurrence was significantly more common in the low-GNRI group (p=0.008). CONCLUSION: Low-GNRI was an independent risk factor for OS and RFS after radical resection of esophageal cancer. The preoperative GNRI may be a useful prognostic factor after esophageal cancer surgery.

The clinical impacts of the prognostic nutritional index for the esophageal cancer patients who received curative treatment.

BACKGROUND: We investigated the impact of the prognostic nutritional index (PNI) on esophageal cancer survival and recurrence after curative treatment. METHODS: This study included 120 patients who underwent curative surgery followed by the adjuvant treatment for esophageal cancer between 2008 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. RESULTS: The PNI of 49 was regarded to be the optimal critical point of classification considering the 1-year, 3-year, and 5-year survival rate. The OS rates at three and five years after surgery were 47.4% and 36.0% in the PNI low group, respectively, and 62.5% and 56.5% in the PNI high group, which amounted to a statistically significant difference (P = 0.020). The RFS rates at three and five years after surgery were 31.0% and 24.8% in the PNI low group, respectively, and 50.9% and 42.8% in the PNI high group, which amounted to a statistically significant difference (P = 0.020). A multivariate analysis demonstrated that the PNI was a significant independent risk factor for the OS and a marginally significant independent risk factor forRFS. CONCLUSION: The PNI was a risk factor for survival in patients who underwent curative treatment for esophageal cancer. It is necessary to develop the effective plan of the perioperative care and the surgical strategy according to the PNI.

The Clinical Influence of Geriatric Nutritional Risk Index in Patients With Gastric Cancer Who Receive Curative Treatment.

BACKGROUND/AIM: We evaluated the clinical impact of the Geriatric Nutritional Risk Index (GNRI) in patients who received curative treatment and perioperative adjuvant treatment. We also investigated the association between the GNRI and the clinicopathological features of patients with GC. PATIENTS AND METHODS: This study included 280 patients who underwent curative treatment for GC between 2005 and 2020. The prognosis and clinicopathological parameters of the high-GNRI and low-GNRI groups were compared. RESULTS: In the GNRI-high group, the overall survival (OS) rates at 3 and 5 years after surgery were significantly lower (82.7% and 77.9%, respectively) than those in the GNRI-low group (56.4% and 40.8%). The GNRI was selected for the final multivariate analysis model for OS. The GNRI was also a significant prognostic factor for recurrence-free survival (RFS). The RFS rates at 3 and 5 years after surgery were 79.1% and 74.8%, respectively, in the GNRI-high group, and 48.0% and 38.6% in the GNRI-low group. The GNRI was selected for the final multivariate analysis model for RFS. The GNRI was also found to affect the postoperative clinical course, including postoperative surgical complications and postoperative adjuvant chemotherapy. CONCLUSION: The GNRI may be a promising prognostic and predictive factor for gastric cancer. In the future, the GNRI may be used to select optimal treatment strategies.

Clinical Course of Vitamin B12 Deficiency and Associated Risk Factors in Patients After Total Gastrectomy for Gastric Cancer.

BACKGROUND/AIM: Patients are at-risk for vitamin B12 deficiency after total gastrectomy due to a lack of intrinsic factors. The aim of the study was to clarify the clinical course and risk factors for vitamin B12 deficiency after total gastrectomy for gastric cancer patients. PATIENTS AND METHODS: Patients who underwent curative resection for gastric cancer were selected from the medical records of the Yokohama City University from 2000 to 2020. A logistic regression analysis was performed to identify risk factors for vitamin B12 deficiency. RESULTS: We evaluated 47 patients. The median serum vitamin B12 levels before surgery were 359 pg/ml, while those at 3, 6, 9, and 12 months after surgery these were 255 pg/ml, 197.5 pg/ml, 195 pg/ml, and 206 pg/ml, respectively. Univariate analyses to identify factors associated with vitamin B12 deficiency at 6 months after surgery showed that the occurrence of postoperative complications was a significant risk factor (OR=6.347, 95%CI=1.607-25.774, p=0.009), while adjuvant chemotherapy was a marginally significantly risk factor (OR=3.562, 95%CI=0.877-14.477, p=0.076). CONCLUSION: Almost half of the patients were diagnosed with vitamin B12 deficiency at 6 months after total gastrectomy for gastric cancer. In addition, the occurrence of postoperative complications and adjuvant chemotherapy were risk factors for vitamin B12 deficiency at 6 months after surgery.

The Albumin-Bilirubin Score Is a Prognostic Factor for Gastric Cancer Patients Who Receive Curative Treatment.

BACKGROUND/AIM: The albumin-bilirubin (ALBI) score is a promising tool for the evaluation of the perioperative hepatic function. The present study aimed to evaluate the clinical impact of the preoperative ALBI status in patients with gastric cancer (GC) who received curative treatment. PATIENTS AND METHODS: The present study included 244 patients who underwent curative treatment for GC between 2005 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. RESULTS: Based on the 3- and 5-year OS rates, we set the cut-off value for the ALBI score at -2.7849. The 3- and 5-year OS rates were 87.3% and 80.9%, respectively, in the ALBI-low group, and 66.9% and 60.6% in the ALBI-high group; these differences were statistically significant (p<0.001). The ALBI score was included in the final multivariate analysis model [Hazard ratio (HR)=2.120, 95% confidence interval (CI)=1.177-3.818, p=0.012]. Similar results were observed for RFS. In addition, the ALBI score correlated with the introduction of postoperative adjuvant chemotherapy. CONCLUSION: The preoperative ALBI score correlated with both the OS and RFS of GC patients as well as the clinical course of adjuvant chemotherapy. Taken together, the ALBI score is a promising prognostic factor for GC.

Clinical Impact of Preoperative Albumin-Bilirubin Status in Esophageal Cancer Patients Who Receive Curative Treatment.

BACKGROUND/AIM: The albumin-bilirubin (ALBI) score, which evaluates the perioperative liver function, was developed, and had a clinical impact on both the short- and long-term oncological outcomes in some malignancies. We evaluated the clinical impact of preoperative albumin-bilirubin status in patients with resectable esophageal cancer who received curative treatment. PATIENTS AND METHODS: The study included 121 patients who underwent curative surgery followed by adjuvant chemotherapy for esophageal cancer between 2005 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. RESULTS: Based on the 3- and 5-year OS rates, we set the cut-off value for the ALBI score at -2.7. Eighty patients were classified into the ALBI-low group (ALBI score <-2.7), 41 patients were categorized into the ALBI-high group (ALBI score >-2.7). The 3- and 5-year OS rates were 62.2% and 53.2%, respectively, in the ALBI-low group, and 42.2% and 35.2% in the ALBI-high group. There was a significant difference in OS (p=0.0113). The 3- and 5-year RFS rates were 43.1% and 40.3%, respectively, in the ALBI-low group and 37.7% and 26.1% in the ALBI-high group. There was a significant difference in RFS (p=0.048). When comparing the perioperative clinical course between the ALBI-high and ALBI-low groups, the incidence of postoperative anastomotic leakage was 46.3% (19/41) in the ALBI-high group, and 27.5% (22/80) in the ALBI-low group (p=0.038). CONCLUSION: The ALBI status had a clinical impact on both OS and RFS in esophageal cancer patients. Therefore, ALBI may have potential application as a prognostic factor for esophageal cancer patients.

[Effectiveness of L-Carnitine in the Treatment of Fatigue Associated with Chemotherapy in Patients with Gastric Cancer].

AIM: Low serum carnitine levels have been reported in patients with cancer receiving chemotherapy and are considered one of the factors causing fatigue associated with chemotherapy. We evaluated the effectiveness of L-carnitine in the treatment of fatigue associated with chemotherapy in patients with gastric cancer(GC). MATERIALS AND METHODS: We performed a randomized controlled trial between December 2013 and December 2018. Untreated patients with advanced GC were included in the study; 1 patient developed an allergy after receiving the first chemotherapy and was excluded from the study. The primary endpoint was brief fatigue inventory(BFI). Patients were categorized into 2 groups: those who received L-carnitine oral supplements(group C)and those who did not receive L-carnitine oral supplements(group N). RESULTS: The serum carnitine levels were improved significantly in group C compared with group N. BFIwas more aggravated in group N than group C; however, the difference was not significant. CONCLUSION: We could not demonstrate the effectiveness of L-carnitine in the treatment of fatigue associated with chemotherapy in patients with GC.

[A Case of Sigmoid Colon Cancer Accompanied by Intestinal Malrotation Treated by Laparoscopic Surgery].

A 52-year-old man whose fecal occult blood test was positive was found to have type 2 sigmoid colon cancer by colonoscopy. On enhanced barium enema study, the cecum was in the pelvis, and the ascending colon was running medially in the abdomen. Enhanced CT scan of the abdomen revealed rotation of the superior mesenteric vein(SMV). We diagnosed the case as sigmoid colon cancer(cT3N0M0, StageⅡA)with non rotation-type intestinal malrotation, and performed laparoscopic surgery. We confirmed the small intestine to be located on the right side of the abdomen, the cecum to be located in the pelvis, and the ascending colon to be running medially in the abdomen. The ascending mesocolon was adherent to the right of the sigmoid mesocolon. Following dissections of the ascending mesocolon from the sigmoid mesocolon, we performed surgery via the inside approach as usual. We dissected the root of the inferior mesenteric artery(IMA), and the operation was completed. In laparoscopic surgery for colorectal cancer with intestinal malrotation, there are some reports that it could be performed safely if attention is paid to adhesion of the mesenteries and vascular variation in the course of preoperative imaging diagnosis. We report a case of laparoscopic surgery that could be safely performed for sigmoid colon cancer with non rotation-type intestinal malrotation.

Randomized phase II study of TJ-54 (Yokukansan) for postoperative delirium in gastrointestinal and lung malignancy patients.

The present study evaluated the efficacy and safety of TJ-54 (Yokukansan; a traditional Japanese medicine) for the prevention and/or treatment of postoperative delirium in a randomized phase II trial of patients receiving surgery for gastrointestinal and lung malignancies. Patients ≥70 years of age who underwent surgery for gastrointestinal or lung malignancy were eligible for participation in the study. The 186 eligible patients were randomly assigned at a 1:1 ratio to receive TJ-54 or control during their peri-operative care (between 7 days prior to surgery and 4 days following surgery, except for the operation day). The signs and symptoms of delirium were assessed using the Diagnostic and Statistical Manual of Mental Disorders-IV by the investigator during the peri-operative period. A total of 186 eligible gastrointestinal or lung malignancy patients were analyzed (93, TJ-54; 93, control). There were no marked differences between the two randomized groups. The incidence of delirium was 6.5% (6 patients) in the TJ-54 group and 9.7% (9 patients) in the control group, with no significant difference (P=0.419). However, of the patients categorized with a mini-mental state examination (MMSE) score of ≤26, the incidence of postoperative delirium was 9.1% in the TJ-54 group and 26.9% in the control group [risk ratio, 0.338; 95% confidence interval (0.078-1.462), P=0.115]. Treatment with TJ-54 reduced the incidence of postoperative delirium compared with the control group. Although TJ-54 did not demonstrate any contribution to preventing or treating postoperative delirium in patients following surgery for gastrointestinal or lung malignancy, TJ-54 reduced the risk of postoperative delirium in the patients who were classified as MMSE ≤26. Further phase III studies with a larger sample size are required in order to clarify the effects of TJ-54 against postoperative delirium.

Does herbal medicine reduce the risk of hepatocellular carcinoma?

Many herbal medicines are effective anti-inflammatory agents and may therefore suppress the development of hepatocellular carcinoma (HCC). Recently, treatment with a single-tablet regimen containing ledipasvir and sofosbuvir resulted in high rates of sustained virologic response among patients with hepatitis C virus genotype 1 infection who did not respond to prior interferon-based treatment. Patients with chronic hepatitis C are expected to receive this treatment worldwide. However, many patients have hepatitis-like fatty liver and nonalcoholic steatohepatitis. A strategy to prevent the development of HCC in this subgroup of patients is urgently required. Whether herbal medicines can suppress the development of HCC remains to be established. However, herbal medicines are effective anti-inflammatory agents and may inhibit the development of HCC. Clinical trials exploring the effectiveness of herbal medicines in the prevention and treatment of HCC are therefore warranted. The current lack of knowledge and of educational programs is a barrier to increasing the use of potentially effective herbal medicines and performing prospective clinical trials.

[Effect of enteral nutrition enriched with eicosapentaenoic acid on body weight loss and compliance with S-1 adjuvant chemotherapy after gastric cancer surgery].

BACKGROUND: Eicosapentaenoic acid-enriched oral nutritional supplements (Prosure®; Abbott Japan, Tokyo, Japan) may attenuate surgical stress and catabolism after gastric cancer surgery. The present study aimed to evaluate the effects of Prosure® on body weight loss( BWL) and compliance with S-1 adjuvant chemotherapy after gastrectomy. PATIENTS AND METHODS: Patients who underwent curative total gastrectomy for gastric cancer were selected to undergo adjuvant S-1 chemotherapy at Kanagawa Cancer Center between December 2010 and October 2011. The patients received a normal postgastrectomy diet and two 240 mL packs of Prosure® for 21 postoperative days. BWL was defined as %BWL and calculated as %BWL=(preoperative body weight-1-month postoperative body weight)×100/preoperative body weight. Time to S-1 treatment failure was calculated. RESULTS: Five patients were enrolled in this study. The median age was 62.0 years. One patient was male, and 4 were female. The 1-month postoperative BWL was 92.1%. Compared to our previous report, a 20% risk reduction was observed in this study (Prosure® group vs control group, 92.1% vs 89.7%). Moreover, all the patients continued with the S-1 adjuvant chemotherapy for longer than 6 months. CONCLUSION: Prosure® may inhibit BWL at 1 month after gastrectomy. Moreover, Prosure® improved the patients' compliance with the adjuvant chemotherapy after gastrectomy.

[Modified FOLFIRI (l-LV, 5-fluorouracil and irinotecan) therapy for Japanese patients with metastatic colorectal cancer].

PURPOSE: As a project of the Kanagawa Colorectal Cancer Study Group, we performed this study to analyze the efficacy and the safety of modified FOLFIRI (irinotecan: 150 mg/m2) therapy for Japanese patients with metastatic colorectal cancer. PATIENTS AND METHODS: We treated PS 0-1 Japanese patients with measurable or assessable colorectal cancer who either had not received preliminary treatment, or were postoperative with metastasis and had undergone radiation therapy or adjuvant chemotherapy before more than four weeks, and further had provided written acceptance of our proposed procedures. Twenty patients received modified FOLFIRI therapy as a 2-hour infusion of CPT-11 150 mg/m/2 and l-LV 200 mg/m2 followed by a bolus 5-FU 400 mg/m/2 and 46-hour infusion 5-FU 2, 400 mg/m2. Tumor response was assessed by RECIST and toxicity by NCI-CTC. RESULTS: Thirty males and seven females underwent an average 10 courses of treatment. This therapy achieved a 50% response rate, 80%disease-control rate, and 316+/-40 days PHS. Regarding hematological toxicity, 11 patients (55%) experienced leukemia, which developed to grade 3/4 in 5 (25%) of them. Twelve patients (65%) experienced neutropenia, which developed to grade 3/4 in 10 (50%) of them. Digestive toxicity was observed in 16 patients (80%), which developed to grade 3/4 in only one patient (5%) with gastric ulcer. Six patients (30%) experienced alopecia, which was grade 1/2 only. CONCLUSION: This clinical study was safely carried out. The efficacy was as good as in previous reports using a regular dose of CPT-11.

Reduction therapy of alanine aminotransferase levels prevent HCC development in patients with HCV-associated cirrhosis.

BACKGROUND: To find a way to prevent the development of hepatocellular carcinoma (HCC) from hepatitis C virus-associated liver cirrhosis (HCV-LC), an analysis of the HCV-LC patients who had received reduction therapy of the alanine aminotransferase (ALT) levels was performed. PATIENTS AND METHODS: Seventy-four consecutive HCV-LC patients of Child Stage A were followed for >10 years for the development of HCC. They were divided into two groups: in group A, the reduction therapy for the ALT levels was aggressively performed, while in group B, the reduction therapy was not performed aggressively. The patients were subdivided into three sub-groups according to their serum ALT levels. In groups A and B, the high ALT group was comprised, respectively, of nine and five patients whose annual average serum ALT levels were persistently high (> or =80 IU), while the low ALT group was comprised of 19 and 20 patients whose annual average serum ALT levels were persistently low (<80 IU). The remaining eleven and ten patients had annual average serum ALT levels which fluctuated and were unclassified (unclassified group). RESULTS: In group B, 65.7% of the patients had developed HCC in 13 years, in contrast to only 41.0% of group A (p=0.039). In group A, the median HCC development time was 12.8 years, in contrast to only 3.8 years in group B (p=0.0013). Multivariate analysis demonstrated that the mode of reduction therapy and ALT levels were the significant factors affecting HCC development. CONCLUSION: The chances of surviving for more than ten years without developing HCC for HCV-LC patients
