RESUMO
Ectopic varices due to extrahepatic portal vein obstruction (EHO) after hepaticojejunostomy have been previously reported. However, few case reports have described angiodysplasia-like lesions due to EHO around the hepaticojejunal anastomosis because they comprise small vessels in the mucosal surface and cannot be detected by contrast-enhanced computed tomography. Physicians need to insert the endoscope into the long afferent limb to diagnose angiodysplasia-like lesions around the hepaticojejunal anastomosis. Some reports have described that endoscopy stops bleeding from angiodysplasia-like lesions around the hepaticojejunal anastomosis; however, a standard methodology remains to be established. We present three cases of bleeding from an angiodysplasia-like lesion around the hepaticojejunal anastomosis that were successfully treated using argon plasma coagulation (APC) with balloon-assisted enteroscopy. Although one patient died owing to cancer progression 3 months after APC hemostasis, the hemostatic effect persisted for >2 years in the remaining two patients. These results suggest that APC is a good treatment option to stop bleeding from angiodysplasia-like lesions at hepaticojejunal anastomosis.
RESUMO
The effect of anti-epidermal growth factor receptor (EGFR) antibody-containing chemotherapy on appendiceal signet-ring cell carcinoma (SRCC) remains unknown. Herein, we report three patients, diagnosed as having synchronous metastases, who underwent this treatment for unresectable appendiceal SRCC with RAS wild type. Cases 1, 2, and 3 received FOLFOX with panitumumab, FOLFOX with cetuximab, and FOLFIRI with cetuximab, respectively, and their progression-free survival were 6.2, 7.2, and 18.7 months, respectively. The subsequent anti-vascular endothelial growth factor antibody-containing therapy was ineffective, and their overall survival was 8.2, 11.4, and 22.9 months, respectively. The anti-EGFR antibody-containing chemotherapy showed moderate efficacy for appendiceal SRCC. Further studies including molecular analysis should be needed.
RESUMO
Background: Asthma, chronic obstructive pulmonary disease (COPD), and asthma-COPD overlap (ACO) are complex and heterogeneous diseases that share clinical characteristics (phenotypes) and molecular mechanisms (endotypes). Whilst physicians make clinical decisions on diagnostic groups, for some such as ACO there is no commonly accepted criteria. An alternative approach is to evaluate phenotypes and endotypes that are considered to respond well to a specific type of treatment ("treatable traits") rather than diagnostic labels. Purpose: The prospective, longitudinal, and observational TRAIT study will evaluate disease characteristics, including both phenotypes and endotypes, in relation to the presentation of obstructive respiratory disease characteristics in patients diagnosed with asthma, COPD, or ACO in Japan, with the aim of further understanding the clinical benefit of a treatable traits-based approach. Patients and Methods: A total of 1500 participants will be enrolled into three cohorts according to their treating physician's diagnosis of asthma, COPD, or ACO at screening. Part 1 of the study will involve cross-sectional phenotyping and endotyping at study enrollment. Part 2 of the study will evaluate the progression of clinical characteristics, biomarker profiles, and treatment over a 3-year follow-up period. The follow-up will involve three annual study visits and three telephone calls scheduled at 6-month intervals. A substudy involving 50 participants from the asthma cohort (in which the ratio will be approximately 1:1 including 25 participants with a smoking history of ≥10 pack-years and 25 participants with no smoking history), 100 participants from the ACO cohort, and 100 participants from the COPD cohort will evaluate disease phenotypes using inspiratory and expiratory computed tomography scans. Conclusion: TRAIT will describe clinical characteristics of patients with obstructive respiratory diseases to better understand potential differences and similarities between clinical diagnoses, which will support the improvement of personalized treatment strategies.

A durable response after the discontinuation of immune checkpoint-inhibitor therapy has previously been reported in several cancers. We herein describe a patient with gastric cancer who maintained a durable response after the discontinuation of nivolumab. A 65-year-old man was treated with nivolumab as a sixth-line therapy for recurrent gastric cancer. After four cycles of nivolumab therapy, he showed a partial response. But the treatment was discontinued when two immune-related adverse events occurred after six cycles. Disease regression was sustained for approximately 2 years, without the re-administration of nivolumab. The characteristics leading to such responses are unclear, and further studies are warranted in this regard.

BACKGROUND: Fluticasone furoate (FF)/vilanterol (VI) is a once daily (OD) inhaled corticosteroid/long-acting ß2-agonist combination asthma therapy approved in Japan and the EU. FF/VI efficacy and safety data from asthma studies including patients in East Asia were evaluated to assess ethnic sensitivity. METHODS: Randomized, double-blind, multicenter Phase IIb/III trials were assessed. Change from baseline relative to placebo or twice-daily fluticasone propionate 500 µg in trough FEV1 was compared between patients from Japan (N = 148) and Not-Japan (N = 3,066; three studies). Adverse events (AEs), laboratory results, and electrocardiograms were compared between patients from Japan + Korea (N = 188) and Not-Japan + Korea (N = 3,840; five studies). RESULTS: For trough FEV1, improvements from baseline (least-squares mean difference [95% confidence interval]) were reported for FF/VI 100/25 µg OD versus placebo at Week 12 (Japan: 0.323 L [0.104-0.542]; Not-Japan: 0.168 L [0.095-0.241]). Improvements from baseline (least-squares mean change [standard error]) were reported with FF/VI 200/25 µg OD at Week 24 (Japan: 0.355 L [0.1152]; Not-Japan: 0.396 L [0.0313]). A greater proportion of patients from Japan + Korea versus Not-Japan + Korea reported AEs in all treatment arms including placebo (FF/VI 100/25 µg: 79% versus 57%; FF/VI 200/25 µg: 64% versus 45%; placebo: 41% versus 23%). There were no notable differences in treatment-related or class-related AEs. No clinically significant changes in electrocardiogram assessments or statistically significant differences in 24 h urinary cortisol excretion were observed between the Japan + Korea and Not-Japan + Korea cohorts. CONCLUSIONS: Good efficacy and an acceptable safety profile were observed for FF/VI 100/25 µg and 200/25 µg OD in East Asian asthma patients; these globally recommended doses are appropriate for asthma patients in Japan.
