Background: We previously reported the feasibility and efficacy of neoadjuvant chemotherapy without radiotherapy for locally advanced rectal cancer. Here, we report the results of a long-term follow-up study.

Methods: This was a multi-institutional, prospective phase 2 study of patients with locally advanced rectal cancer.

Safety of Apixaban Monotherapy for Non-Valvular Atrial Fibrillation-Related Acute Stroke with Intra-/Extracranial Artery Stenosis.

Introduction: We investigated whether apixaban is safe for the prevention of further adverse events in non-valvular atrial fibrillation (NVAF) patients with intra-/extracranial artery stenosis (Stenosis group) compared with acute large vessel occlusion without intra-/extracranial artery stenosis (No stenosis group). We also examined whether combination therapy using apixaban and antiplatelet is safe.

Methods: ALVO (Apixaban on clinical outcome of patients with Large Vessel Occlusion [LVO] or stenosis) was a historical and prospective multicenter registry at 38 centers in Japan.

[A case of unresectable intrahepatic cholangiocarcinoma receiving sustainable pembrolizumab therapy].

A 65-year-old man had unresectable intrahepatic cholangiocarcinoma with a malignant biliary stricture. We used an endoscopic plastic stent to drain the bile. Despite receiving standard chemotherapy, the tumor eventually progressed and cancerous peritonitis developed.

Reperfusion Therapy Brings Apixaban Administration Forward in Patients with Nonvalvular Arterial Fibrillation with Anterior Circulation Large Vessel Occlusion or Stenosis.

Objective: The initiation of anticoagulant administration after large vessel occlusion (LVO) or stenosis with nonvalvular arterial fibrillation (NAVF) is controversial. We evaluate the timing of anticoagulation and its relationship with clinical factors.

Methods: We enrolled 595 anterior circulation LVO or stenosis with NAVF cases from 38 stroke centers.

[Locally Advanced Gastric Cancer Showing Marked Tumor Shrinkage after the First Dose of Nivolumab for Fourth-Line Chemotherapy].

We report a case of locally advanced gastric cancer, which showed marked tumor shrinkage after the first dose of nivolumab. A 75-year-old woman was diagnosed with locally advanced gastric cancer with pancreatic invasion and pyloric stenosis. We performed gastrojejunostomy before chemotherapy.

Effect of prior antiplatelet therapy on large vessel occlusion in patients with non-valvular atrial fibrillation newly initiated on apixaban.

Introduction: We evaluated the effect of prior antiplatelet therapy on large vessel occlusion (LVO) in patients with non-valvular atrial fibrillation (NVAF) newly initiated on apixaban.

Methods: Patients with acute LVO with acute stroke due to NVAF or stenosis with NVAF started on apixaban within 14 days of onset were enrolled. We compared incidence of major bleeding, cerebral hemorrhage, ischemic events, cerebral infarction, and all-cause mortality between patients with and without prior antiplatelet therapy for acute LVO.

Does methotrexate have no beneficial effect in reducing flares in the treatment of polymyalgia rheumatica patients?

We read the article by Marsman et al. regarding the efficacy of methotrexate (MTX) in the treatment of polymyalgia rheumatica (PMR) with great interest. This study added new insights regarding the use of MTX in a real-world clinical setting and its effect on the incidence rates of flares.

[Chronic myeloid leukemia with variant e13a3 (b2a3) BCR-ABL1 as an ABL1 tyrosine kinase inhibitor-sensitive subtype].

We report the case of a 26-year-old male patient with chronic myelogenous leukemia in the chronic phase with the e13a3 (b2a3) variant of BCR-ABL1 fusion. Despite the presence of Philadelphia chromosome and fluorescence in situ hybridization-detectable BCR-ABL1 fusion signals, quantitative measurement of BCR-ABL1 on the ABL1 using a reverse primer in exon 2 of ABL1 failed to detect the fusion transcripts. PCR direct sequencing analysis with a sense primer for exon 13 of BCR and an antisense primer for exon 3 of ABL1 revealed the e13a3 variant of BCR-ABL1 fusion.

Effect of optimal neoadjuvant chemotherapy on oncological outcomes of locally advanced bladder cancer with laparoscopic radical cystectomy: A matched-pair analysis in a multicenter cohort.

Objectives: To assess the effect of optimal neoadjuvant chemotherapy of at least three cycles of cisplatin-based regimen on oncological outcomes of clinical stage T3 or higher bladder cancer treated with laparoscopic radical cystectomy.

Methods: Laparoscopic radical cystectomies carried out at 10 institutions were included in this retrospective study. The outcomes of patients who received optimal neoadjuvant chemotherapy and those who did not receive neoadjuvant chemotherapy were compared using propensity score matching in clinical stage T3-4 or T2 cohorts, separately.

Impact of vascular abnormality on contrast-enhanced CT and high C-reactive protein levels on postoperative pancreatic hemorrhage after pancreaticoduodenectomy: A multi-institutional, retrospective analysis of 590 consecutive cases.

Background: /Objectives: This study aimed to elucidate the efficacy of CT findings and perioperative characteristics to predict post-pancreatectomy hemorrhage (PPH): a critical complication after pancreaticoduodenectomy.

Methods: The records of 590 consecutive patients who underwent pancreaticoduodenectomy at three institutes between 2012 and 2018 were included. The presence of a vascular wall abnormality or ascites with high density (vascular abnormality) on postoperative day (POD) 5-10 contrast-enhanced CT (early CT), perioperative characteristics, and any PPH or pseudoaneurysm formation (PPH events) were analyzed through a multivariate analysis.

Safety of Early Administration of Apixaban on Clinical Outcomes in Patients with Acute Large Vessel Occlusion.

Early administration of direct oral anticoagulants in patients with acute large vessel occlusion (LVO) and nonvalvular atrial fibrillation (NVAF) is a concern, as endovascular therapy (EVT) became highly utilized. We conducted a historical and prospective multicenter registry at 38 centers in Japan from July 2016 to February 2018. Patients aged ≥ 20 years with NVAF and acute LVO or stenosis who received apixaban within 14 days from onset were included.

Perioperative and oncological outcomes of laparoscopic radical cystectomy with intracorporeal versus extracorporeal ileal conduit: A matched-pair comparison in a multicenter cohort in Japan.

Objectives: To compare the perioperative and oncological outcomes of pure laparoscopic intracorporeal ileal conduit urinary diversion versus extracorporeal ileal conduit urinary diversion after laparoscopic radical cystectomy for bladder cancer in a multicenter cohort in Japan.

Method: A total of 455 patients who underwent laparoscopic radical cystectomy carried out at 10 institutions were included in this retrospective study. The perioperative data of the intracorporeal ileal conduit urinary diversion and extracorporeal ileal conduit urinary diversion groups were compared using the propensity score matching method.

Prognostic value of volumetric PET parameters at early response evaluation in melanoma patients treated with immunotherapy.

Purpose: The purpose of this study was to investigate the prognostic value of whole-body metabolic tumor volume (MTV) and other metabolic tumor parameters, obtained from baseline and first restaging F-FDG PET/CT scans in melanoma patients treated with immune checkpoint inhibitors (ICIs).

Methods: Eighty-five consecutive melanoma patients (M, 57; F, 28) treated with ICIs who underwent PET/CT scans before and approximately 3 months after the start of immunotherapy were retrospectively enrolled. Metabolic tumor parameters including MTV for all melanoma lesions were measured on each scan.

Sex Difference in the Association Between Subtype Distribution and Age at Diagnosis in Patients With Primary Aldosteronism.

Primary aldosteronism (PA) is the most frequent cause of secondary hypertension. Adrenal vein sampling (AVS) is an established method for finding patients with the unilateral subtype of PA, for which adrenalectomy is an applicable treatment. In this study, we analyzed a large database of patients with PA who underwent adrenal vein sampling, to investigate the sex differences in the impact of age at diagnosis on the subtype and cause of PA.
