Using the geriatric nutritional risk index to predict outcomes in older patients with remnant gastric cancer after gastrectomy: a retrospective multicenter study in Japan.

PURPOSE: This study investigated the prognostic value of the geriatric nutritional risk index (GNRI) in patients undergoing curative gastrectomy for remnant gastric cancer (RGC). METHODS: This multicenter retrospective study included 105 patients with RGC of ≥ 65 years of age who underwent curative gastrectomy at 10 institutions in Japan between January 2000 and December 2016. Postoperative complications, overall survival (OS), and disease-specific survival (DSS) were analyzed. RESULTS: Receiver operating curve analyses indicated that the optimal cutoff value of the GNRI for OS was 95.4. Patients were categorized into high and low GNRI groups based on the optimal GNRI cutoff value. The GNRI was significantly correlated with body mass index (p < 0.001), amount of bleeding (p = 0.021), Clavien-Dindo grade 5 postoperative complications (p = 0.040), death caused by primary disease (p = 0.010), and death caused by other diseases (p = 0.002). The OS and DSS were significantly worse in the low GNRI group. A low GNRI and T3 or deeper tumor invasion were independent prognostic factors for OS and DSS. CONCLUSIONS: The GNRI is a promising predictor of both short- and long-term outcomes in older patients with RGC.

Comorbidity Between Crowned Dens Syndrome and Primary Hyperparathyroidism.

Primary hyperparathyroidism (PHPT) is characterized by various symptoms, including malaise, psychiatric symptoms, and hypertension. When hypercalcemia is accompanied by PHPT, it may cause pathologic fractures or lethargy. Additionally, PHPT can be complicated by crowned dens syndrome (CDS). We present a case of a 72-year-old female. She had begun experiencing low back pain during movement five days before. The symptoms progressed and the patient was unable to move. Based on the imaging, blood tests, and clinical findings, the patient was diagnosed with PHPT complicated with CDS. Therefore, it is important to perform a careful physical examination of the neck and cervical spine computed tomography in patients with PHPT. Moreover, measuring calcium levels in patients with CDS may lead to early detection of PHPT.

Intraductal Tubulopapillary Neoplasm Diagnosed Before Surgery: A Case Report.

Intraductal tubulopapillary neoplasm (ITPN) is a rare disease in the pancreas with a better prognosis than pancreatic ductal adenocarcinoma (PDAC) and a different treatment strategy. Therefore, it is important to confirm its diagnosis before the surgery. However, few cases have been diagnosed preoperatively. In this report, we present a case of ITPN that was successfully diagnosed preoperatively. A 70-year-old female patient was incidentally diagnosed with a pancreatic tumor. The patient was asymptomatic, and her blood tests were all within the normal range. A dynamic computed tomography scan showed an indistinct mass with small cysts and a dilated pancreatic duct. The mass was well contrasted in the arterial phase. These findings were not enough to confirm ITPN. Therefore, endoscopic ultrasonography fine needle aspiration biopsy was performed. The specimen had no mucin and the neoplastic cells exhibited a tubulopapillary growth pattern. Moreover, the neoplastic cells were immunohistochemically positive for MUC1, CK7, and CK20, but negative for MUC2, MUC5AC, synaptophysin, and Bcl-10. Consequently, the preoperative diagnosis was confirmed as ITPN. Hence, a subtotal-stomach-preserving pancreaticoduodenectomy was performed, and the patient had a good postoperative course and was discharged after 26 days. Tegafur, gimeracil, and oteracil were administered as postoperative adjuvant chemotherapies for one year. Seventeen months after the surgery, no recurrence has been detected. ITPN and PDAC have different prognoses and treatment strategies. In this report, we experienced a case of ITPN preoperatively diagnosed and successfully treated.

The prognostic impact of the lymphocyte-to-C-reactive protein ratio in patients with unresectable or recurrent advanced gastric cancer treated with first- and second-line treatment.

PURPOSE: The goal of this study was to determine which markers are the most useful as first- and second-line pre-treatment markers in patients with unresectable or recurrent gastric cancer (URGC). METHODS: This study included 101 URGC patients who were treated with first- and second-line chemotherapy. Several prognostic scores based on nutrition and inflammation were analyzed using a receiver operating characteristic (ROC) analysis to determine the most useful prognostic marker. RESULTS: The lymphocyte-to-C-reactive protein ratio (LCR) had the highest area under the curve for both first- and second-line chemotherapy, according to an ROC analysis. An ROC analysis was used to determine the optimal LCR cut-off for the median survival time before first- and second-line chemotherapy, and patients were divided into high- and low-LCR groups. Patients with a high LCR had a significantly longer survival than those with a low LCR before first- and second-line chemotherapy (p = 0.004, p < 0.001, respectively). A low LCR before both first- and second-line chemotherapy was an independent poor prognostic factor in a multivariate analysis. CONCLUSIONS: URGC patients with a low LCR before both first- and second-line chemotherapy had a significantly worse prognosis than those with a high LCR in this study. Nutritional intervention during chemotherapy induction may lead to a better prognosis.

Impact of geriatric nutritional risk index on outcomes after gastrectomy in elderly patients with gastric cancer: a retrospective multicenter study in Japan.

BACKGROUND: Several studies investigated the utility of inflammation and nutritional markers in predicting the prognosis in patients with gastric cancer; however, the markers with the best predictive ability remain unclear. This retrospective study aimed to determine inflammation and nutritional markers that predicted prognosis in elderly patients over 75 years of age undergoing curative gastrectomy for gastric cancer. METHODS: Between January 2005 and December 2015, 497 consecutive elderly gastric cancer patients aged over 75 years underwent curative gastrectomy in 12 institutions. The geriatric nutritional risk index (GNRI), prognostic nutritional index, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, and C-reactive protein/albumin ratio were examined as prognostic markers for overall survival (OS) and disease-specific survival (DSS) using area under the curve (AUC) using receiver operating characteristic (ROC) curve analysis. RESULTS: The GNRI had the highest AUC and predictive value for both OS (0.637, p < 0.001) and DSS (AUC 0.645, p < 0.001). The study cohort was categorized into the high and low GNRI groups based on the optimal GNRI cut-off values for OS (97.0) and DSS (95.8) determined with the ROC analysis. For both OS and DSS, there was a significant correlation between the GNRI and several clinicopathological factors including age, body mass index, albumin, American Society of Anesthesiologists physical status score, depth of tumor invasion, lymph node metastasis, lymphatic invasion, pathological stage, operation duration, bleeding, procedure, approach, death due to primary disease, and death due to other disease. The GNRI remained a crucial independent prognostic factor for both OS (Hazard ratio [HR] = 1.905, p < 0.001) and DSS in multivariate analysis (HR = 1.780, p = 0.043). CONCLUSIONS: Among a panel of inflammation and nutritional markers, the GNRI exhibited the best performance as a prognostic factor after curative gastrectomy in elderly patients with gastric cancer, indicating its utility as a simple and promising index for predicting OS and DSS in these patients.

CA19-9 in combination with P-CRP as a predictive marker of immune-related adverse events in patients with recurrent or unresectable advanced gastric cancer treated with nivolumab.

BACKGROUND: Immune-check point inhibitors (ICPIs) for treatment of cancer patients sometimes induce potentially life-threatening immune-related adverse events (irAEs), which predict ICPIs treatment efficacy. Prediction of irAEs would be useful for management of irAEs and prediction of ICPIs efficacy. This study aimed to determine predictors of irAEs in patients with recurrent or unresectable advanced gastric cancer (RUGC) treated with nivolumab. METHODS: Seventy-eight RUGC patients treated with nivolumab at nine institutions between January 2017 and April 2020 were included in this study. The usefulness of specific blood test results as predictors of irAEs was evaluated. RESULTS: We observed irAEs in 15 (19.2%) patients. The disease control rate was significantly higher in the patients with irAEs than in those without (86.7% vs. 42.9%; P < 0.001). The median progression-free survival was significantly longer for patients with irAEs than for patients without (4.9 vs. 2.6 months; P = 0.018). The median survival time was longer for patients with irAEs than for those without (9.4 vs. 5.8 months; P = 0.041). The receiver operating characteristic (ROC) curves for irAEs indicated that the area under the curve (AUC) of carbohydrate antigen 19-9 (CA19-9) was highest (0.692; P = 0.022), followed by that for the platelet count × serum C-reactive protein (P-CRP) value (0.680; P = 0.032). The AUC for the CA19-9 + P-CRP combination was 0.782, which was more useful than that for either component and significantly associated with overall survival of nivolumab-treated RUGC patients. CONCLUSIONS: The CA19-9 + P-CRP combination was predictive of irAEs and prognosis in RUGC patients.

Characteristics of sarcopenia after distal gastrectomy in elderly patients.

Presence of preoperative sarcopenia is a risk factor for postoperative complications. However, there are few reports on the presence of sarcopenia and its characteristics following gastrectomy. Sarcopenia is closely related to quality of life in elderly people. To date, the main purpose of follow-up after gastrectomy is surveillance for early detection of recurrence and secondary cancer. However, henceforth, quality of life in elderly gastric cancer patients after gastrectomy must also be evaluated. The present study aimed to investigate sarcopenia during a 1-year postoperative course in elderly gastric cancer patients and examine their characteristics. The subjects were 50 patients aged ≥70 years who underwent laparoscopy-assisted distal gastrectomy for gastric cancer and who experienced no recurrence 1 year postoperatively. Height, weight, serum albumin levels, food intake amount, grip strength, gait speed, visceral fat area, and appendicular skeletal muscle mass index were measured preoperatively and 6 months and 1 year postoperatively. Sarcopenia, obesity, and visceral obesity were diagnosed. Compared with preoperatively, indicators other than height decreased 6 months postoperatively. Compared with 6 months postoperatively, body weight, amount of food intake, and visceral fat area increased by 1 year postoperatively, unlike appendicular skeletal muscle mass index. The frequency of sarcopenia increased 6 months postoperatively compared with preoperatively; this frequency remained almost unchanged 1 year postoperatively compared with 6 months postoperatively. Further, the frequency of visceral obesity increased 1 year postoperatively compared with 6 months postoperatively. Weight increased after > 6 months postoperatively; however, most of the weight increase was in terms of fat and not muscle. We emphasize the importance of considering postoperative sarcopenia and visceral obesity. In particular, sarcopenia and visceral obesity should be carefully monitored after increases in body mass index and food consumption.

Internal supravesical hernia repaired via the anterior approach alone: A case report.

INTRODUCTION: Internal supravesical hernia is one of the rarest types of inguinal hernia. The hernial orifice is surrounded by the transverse vesical fold, median umbilical fold, and medial umbilical fold. PRESENTATION OF CASE: A 75-year-old male presented with lower abdominal pain and nausea. Plain abdominal CT showed that the bladder was suppressed by small bowel near the left internal inguinal ring. A part of the small bowel wall seemed to be inlaid, and so the patient was diagnosed with a strangulated left inguinal hernia. The hernia repair operation was performed via the anterior approach. There was no internal hernial sac found, but there was a walnut-sized mass in the properitoneal space. A diagnosis was made intraoperatively of internal supravesical hernia with strangulated small bowel. Small bowel resection and hernial orifice closure were performed. DISCUSSION: Although internal supravesical hernia can present with distinctive CT findings, preoperative diagnosis is extremely difficult. Internal supravesical hernia in previous reports has been repaired via open laparotomy or laparoscopic surgery; however, we successfully repaired this intraoperatively-diagnosed internal supravesical hernia by the anterior approach alone. CONCLUSION: The patient with internal supravesical hernia diagnosed intraoperatively could be treated via the anterior approach alone successfully. Depending on the situation, the anterior approach can be an option.

[Long-term disease-free survival by S-1 therapy in a case of gastric cancer with peritoneal dissemination].

The patient was a 77-year-old woman who underwent gastrectomy for gastric cancer. Since the patient had positive peritoneal washing cytology and positive peritoneal dissemination, she was started on oral S-1 therapy post-surgery for 4 weeks, followed by a 2-week rest period. During the first course of therapy, her white blood cell count decreased; therefore, the regimen was changed to a 1-week administration, followed by a 1-week rest period. No subsequent adverse events were noted. The patient has experienced no relapse in the four years she has been followed up after surgery in our outpatient clinic. We report our experience with an elderly patient for whom S-1 monotherapy was effective in the treatment of gastric cancer with peritoneal dissemination.
