RESUMO
BACKGROUND: Patients presenting with inoperable colon cancer at first onset (ICF) or at time of relapse (ICR) are considered in unrecoverable. The therapeutic goal for unrecoverable cancer is to prolong overall survival (OS) and maintain a high quality of life (QOL). As data on objective indicators of QOL in cancer patients, such as length of hospitalisation (LOH), outpatient consultation times (OCT), and hospital-free survival (HFS), is limited, this study compared ICF and ICR with respect to OS and QOL over the entire clinical course. METHODS: We retrospectively evaluated 90 inoperable colon cancer patients with chemotherapy and compared ICF and ICR in terms of OS, LOH, OCT, and HFS. RESULTS: Patients with ICF had a worse OS than those with ICR. In patients with ICF and ICR, OS and LOH were not correlated but OS and OCT and OS and HFS were strongly correlated. In patients with ICF and ICR, OCT and HFS accounted for approximately 8% and 90% of their OS, respectively. CONCLUSIONS: The LOH, OCT, and HFS are important factors for evaluating objective QOL of patients with inoperable colon cancer and should be considered when making treatment decisions.

BACKGROUND: Nivolumab has changed the treatment of advanced gastric cancer (AGC). Nivolumab shows better outcomes compared to best supportive care among AGC patients who received at least two prior regimens. However, there are no reliable data regarding AGC patients with poor performance status (PS) who received nivolumab. We investigated the efficacy and safety of nivolumab among AGC patients with poor PS. METHODS: We retrospectively collected clinicopathologic data from patients with AGC who underwent nivolumab monotherapy at our institution from October 2017 to June 2019. RESULTS: Forty-nine AGC patients who received nivolumab were assessed. Twenty-seven patients had PS 0 or 1 (Good group) and 22 had PS 2 or 3 (Poor group). The median progression-free survival and overall survival durations were 2.0 and 6.0 months in the Good group, respectively, and 1.2 and 2.8 months in the Poor group, respectively. The overall survival was significantly shorter in the Poor group (6.0 vs 2.8 months, p = 0.0255). The disease control rates were 23 and 9% in the Good and Poor groups, respectively. Thirty-three percent of patients experienced immune-related adverse events in the Good group, and 18% in the Poor group. CONCLUSION: Nivolumab is feasible but insufficient as third- or later-line treatment for AGC patients with poor PS.

BACKGROUND AND AIMS: Although the usefulness of propofol sedation during endoscopic submucosal dissection (ESD) for gastric neoplasms was reported previously, information is limited on its use in elderly patients. We investigated the safety and efficacy of propofol sedation with a target-controlled infusion (TCI) pump and bispectral index (BIS) monitoring system (TCI/BIS system) in elderly patients during gastric ESD. METHODS: Included were 413 consecutive gastric ESD procedures involving 455 lesions (379 patients) performed in patients under propofol sedation with a TCI/BIS system between October 2009 and September 2013. Patients were divided into 3 groups: group A, age <70 years (n = 162); group B, age ≥70 and <80 years (n = 171); and group C, age ≥80 years (n = 80). We compared the propofol dose and adverse events (eg, hypotension and hypoxemia) during ESD. RESULTS: Older groups required a lower target concentration of propofol (group A: median 2.1 µg/mL [interquartile range (IQR), 1.9-2.3]; group B: median 1.6 µg/mL [IQR, 1.3-1.8]; and group C: median 1.4 µg/mL [IQR, 1.2-1.6]; P < .0001). Hypotension tended to occur in the younger group, and hypoxemia occurred at a significantly higher rate in the older groups, although the number of cases was small. Low preoperative systolic blood pressure (≤125 mm Hg) was associated with hypotension (odds ratio [OR], 1.73; 95% confidence interval [CI], 1.12-2.70; P = .013) and abnormal pulmonary function was associated with hypoxemia in groups B and C (OR, 4.54; 95% CI, 1.01-31.5; P = .048). CONCLUSIONS: Elderly patients required lower doses of propofol with the TCI/BIS system than younger patients. Attention to hypoxemia is necessary in elderly patients, particularly patients with abnormal pulmonary function.

BACKGROUND/AIMS: Because peroral double-balloon endoscopy (DBE) is a time-consuming, painful procedure, sedation with analgesics, and/or anesthetics is generally required. The aim of this prospective study was to investigate the safety and efficacy of our sedation protocol for peroral DBE, which consisted of target-controlled infusion (TCI) anesthesia with propofol, an intravenous bolus of pentazocine, and bispectral index (BIS) monitoring. METHODS: A total of 34 consecutive patients who underwent DBE by the oral approach were enrolled. Patients were primarily sedated with a continuous infusion of propofol and adjusted in accordance with the BIS levels. The bolus infusion of pentazocine was performed when the propofol infusion was insufficient. The primary outcome measure of this study was to ensure the safety and efficacy of this sedation technique. The secondary purpose was to identify the characteristics of the patient who required the bolus infusion of pentazocine. RESULTS: Five patients (14.7%) required a reduction in the dose of propofol. However, no patient experienced any serious adverse events. All patients (100%) and 80.6% (25/31) of endoscopists answered that the sedation protocol was 'excellent' or 'enough' for peroral DBE. Eleven patients (32.3%) required a bolus injection of pentazocine. Age <60 years and a total procedure time of >70 min were significant risk-factors for pentazocine use. CONCLUSIONS: A combination of propofol via TCI pump, bolus injection of pentazocine as needed, and BIS monitoring was a safe and effective procedure for peroral DBE. Reasonable satisfaction indices were obtained from both patients and endoscopists. Pentazocine was required for young patients and in cases with longer procedure times.

Regorafenib is a standard salvage line therapy used for advanced colorectal cancer (CRC). Recently, trifluridine/tipiracil (TFTD) plus bevacizumab also showed promising efficacy as a salvage line therapy for advanced CRC. However, the efficacy and safety of regorafenib for patients with advanced CRC who have previously received TFTD plus bevacizumab is unclear. We retrospectively collected clinicopathologic data from patients with advanced CRC who received regorafenib after TFTD plus bevacizumab in multiple institutions between April 2017 and June 2020.Thirty-four advanced CRC patients who received regorafenib were analyzed. The median age was 66.5 (range 43-81 years), 11 patients were male, and all had an ECOG performance status(PS) of 0 or 1. Twenty-two patients had left-sided tumors, 18 patients had RAS mutants, and 1 patient had a BRAF V600E mutation. The response rate was 0%, and the disease control rate was 31%. The median progression-free survival was 70 days (95% CI: 56-91), and the overall survival was 233 days (95% CI: 188-324). Treatment was discontinued in 32 patients, and 28 (82%) discontinued treatment due to progressive disease. The major grade 3 and4 toxicities were proteinurea (29%), hypertension (26%), hand-foot syndrome(15%), and platelet decrease (6%). Regorafenib after TFTD plus bevacizumab showed efficacy similar to that of the previous study, and no new adverse events were observed.

BACKGROUND/AIMS: Endoscopic submucosal dissection (ESD) for diverticulum-associated colorectal lesions is generally contraindicated because of the high risk of perforation. Several studies on patients with such lesions treated with ESD have been reported recently. However, the feasibility and safety of ESD for lesions in proximity to a colonic diverticulum (D-ESD) have not been fully clarified. The aim of this study was to evaluate the feasibility and safety of D-ESD. METHODS: D-ESD was defined as ESD for lesions within approximately 3 mm of a diverticulum. Twenty-six consecutive patients who underwent D-ESD were included. Two strategic approaches were used depending on whether submucosal dissection of the diverticulum-related part was required (strategy B) or not (strategy A). Treatment outcomes and adverse events associated with each strategy were analyzed. RESULTS: The en bloc resection rate was 96.2%. The rates of R0 and curative resection in strategies A and B were 80.8%, 73.1%, 84.6%, and 70.6%, respectively. Two cases of intraoperative perforation and one case of delayed perforation occurred. The delayed perforation case required emergency surgery, but the other cases were managed conservatively. CONCLUSION: D-ESD may be a feasible treatment option. However, it should be performed in a high-volume center by expert hands because it requires highly skilled endoscopic techniques.
RESUMO
OBJECTIVES: There is no standard chemotherapy for advanced pancreatic cancer (APC) after gemcitabine plus nab-paclitaxel (GP) failure. The aim of this study was to evaluate the efficacy and safety of FOLFIRINOX (5-Fluorouracil, leucovorin, irinotecan, and oxaliplatin) (5-Fluorouracil, leucovorin, irinotecan, and oxaliplatin) (FFX) and modified FFX (mFFX) for APC patients after GP failure. METHODS: We retrospectively evaluated the efficacy and safety of FFX in APC patients who were refractory or intolerant of GP. RESULTS: Between July 2014 and October 2018, 23 patients received FFX after failure of GP. The overall response rate (RR) was 23%, and the disease control rate (DCR) was 68%. The median progression-free survival (PFS) was 5.3 months (95% confidence interval, 2.5-8.9), and the median overall survival (OS) was 12.1 months (95% confidence interval, 4.0-14.2). Twelve patients received FFX, and 11 patients received mFFX. In the FFX group, the RR was 9%, the DCR was 73%, the PFS was 5.3 months, and the OS was 6.9 months. In the mFFX group, the RR was 23%, the DCR was 64%, the PFS was 4.3 months, and the OS was 12.8 months. There was no significant difference between the groups. CONCLUSIONS: FOLFIRINOX has potential activity for patients with APC in whom GP failed.

BACKGROUND: Helicobacter pylori infection is associated with the incidence of gastric cancer. Endoscopic resection has been developed as a proper technique to treat early stage of gastric cancer. However, some patients develop recurrent gastric cancer within 5 years after endoscopic treatment. The aim of the present study is to explore a biomarker for detecting people who has high risk of gastric cancer recurrence. METHODS: We analyzed the Interleukin-10 (IL-10) single nucleotide polymorphism (SNP) and IgG subclass responses to the bacteria in patients with early gastric cancer and recurrent gastric cancer. RESULTS: Patients with hetero-type in the 1082 SNP and CC genotype in the 592 SNP were at high risk of recurrence of gastric cancer. In patients with genotype carrying high risk of recurrence, IgG1 level tended to be higher than that in patients with other genotypes. CONCLUSIONS: Dominance of T helper 2 (Th2) immunity controlled by IL-10 cytokine may be associated with H. pylori-associated gastric cancer recurrence.
RESUMO
BACKGROUND AND STUDY AIMS: Patients receiving antithrombotic drugs have a higher risk of postoperative bleeding and thromboembolic events related to endoscopic procedures. The aim of this study was to evaluate the relationship between various antithrombotic therapies and bleeding after gastric endoscopic submucosal dissection (ESD) (post-ESD bleeding). PATIENTS AND METHODS: Among 529 consecutive gastric ESD procedures (483 patients with 579 legions), 100 patients with 121 lesions who underwent 108 procedures were on antithrombotic therapy (group A) and 382 patients with 458 lesions who underwent 421 procedures were not on antithrombotic therapy (group B). The ratio of post-ESD bleeding between the two groups and the bleeding risk related to various antithrombotic therapies were investigated. RESULTS: Postoperative bleeding was more frequent in group A (11.1â%) than in group B (3.3â%). No thromboembolic events were reported in either group.âFurther investigation of antithrombotic therapies in group A demonstrated that various combinations of antithrombotic agents and heparin replacement were associated with a higher ratio of post-ESD bleeding. Multivariate analyses revealed that dual antiplatelet therapy (odds ratio [OR] 10.9, 95â% confidence interval [CI] 2.1â-â49.5; P â=â0.005) and heparin replacement (OR 34.4, 95â%CI 9.4â-â133.2; P â<â0.001) were associated with the increased risk of post-ESD bleeding. In patients on antiplatelet therapy, post-ESD bleeding tended to occur in the early postoperative period compared with patients on anticoagulant therapy. CONCLUSIONS: It is necessary to be cautious regarding post-ESD bleeding in patients requiring antithrombotic therapy, especially patients receiving dual antiplatelet therapy and heparin replacement. A further prospective study with a large sample will be needed to confirm these findings.

RESUMO
Composite tumors in the stomach composed of adenocarcinoma and neuroendocrine carcinoma are rare. We herein report a case of intramucosal gastric mixed adenoneuroendocrine carcinoma (MANEC) that was treated with endoscopic submucosal dissection (ESD). A 77-year-old man who had previously received ESD for early gastric adenocarcinoma underwent esophagogastroduodenoscopy for screening, which showed a depressed lesion on the lesser curvature of the antrum. The tumor was removed en bloc via ESD and pathologically diagnosed as MANEC. The tumor was located within the mucosal layer, and no lymphovascular invasion was evident. Seven months after the ESD procedure, the patient is currently feeling well without recurrence or metastasis.
