Prognostic Impact of Central Nervous System Recurrence After Surgery in Patients With Epidermal Growth Factor Receptor Mutation-positive Non-small-cell Lung Cancer.

Background/aim: Adjuvant therapy using third-generation tyrosine kinase inhibitors (TKI) demonstrated improved central nervous system (CNS) disease-free survival after surgery in patients with epidermal growth factor receptor (EGFR) mutation-positive lung cancer. However, the prognostic impact of CNS recurrence in surgical patients remains unknown. We evaluated the effect of CNS recurrence on post-recurrence survival (PRS) in patients with postoperatively recurrent NSCLC.

Diagnostic Strategy of Early Stage Pancreatic Cancer via Clinical Predictor Assessment: Clinical Indicators, Risk Factors and Imaging Findings.

Early detection of pancreatic ductal adenocarcinoma (PDAC) in the general population is difficult due to unknown clinical characteristics. This study was conducted to clarify the factors associated with early stage PDAC. Well-known symptoms and factors associated with PDAC were classified into clinical indicators, risk factors, and imaging findings concomitant with early stage PDAC.

Surgical outcomes of totally extraperitoneal repair for inguinal hernia: A retrospective multicenter propensity score-matched study.

Background: Laparoscopic surgical approaches, including total extraperitoneal repair (TEP), have been widely accepted for inguinal hernia repair in Japan. However, there are limited data regarding recurrence after TEP in Japan, given the limited versatility of this procedure. This study retrospectively evaluated the rates of hernia recurrence after TEP and open mesh repair at multiple Japanese centers.

Gluteal muscle metastasis with peritoneal dissemination from gastric cancer during postoperative adjuvant chemotherapy: a case report.

Background: Skeletal muscle metastasis from gastric cancer is rare and has a poor prognosis. We reported a case of gluteal muscle metastasis with peritoneal dissemination from gastric cancer during postoperative adjuvant chemotherapy.

On the 7th dayafter the first administration, he had sudden abdominal pain and nausea. Contrast-enhanced computed tomographyrevealed aortic thrombosis and a superior mesenteric artery(SMA)embolism that was considered to be associated with bevacizumab.

Tadalafil Improves Nocturia and Nocturia-Related Quality of Life in Patients with Benign Prostatic Hyperplasia (KYU-PRO Study).

Introduction: Tadalafil improves lower urinary tract symptoms (LUTS) including nocturia. However, the effect of tadalafil on the nocturia-related quality of life (QoL) is still unknown.

Objective: The effects of tadalafil on nocturia and nocturia-related QoL were evaluated prospectively in patients with benign prostatic hyperplasia (BPH) as a multicenter study.

Long-term outcomes of neoadjuvant-synchronous S-1 plus radiotherapy for locally advanced rectal cancer: a multi-institutional prospective phase II study.

Objectives: This study aimed to evaluate the long-term outcomes of neoadjuvant chemoradiotherapy with S-1 in patients with locally advanced rectal cancer.

Methods: A multi-institutional, prospective, phase II trial was conducted between April 2009 and August 2011. The study enrolled 37 patients with histologically proven rectal carcinoma (T3-4 N0-3 M0) who underwent neoadjuvant chemoradiotherapy with S-1.

Rapid growth of metastatic brain tumor from gastric undifferentiated pleomorphic sarcoma: A case report.

Background: Brain metastasis from undifferentiated pleomorphic sarcoma (UPS) is a rare occurrence, and its clinical course is little known. In this report, we investigate a case of a rapidly growing brain metastasis from gastric UPS.

Case Description: An 82-year-old man with a known gastric tumor, pathologically compatible with UPS, underwent partial gastrectomy at an outside facility.

Comparison Between Contact Force Monitoring and Unipolar Signal Modification as a Guide for Catheter Ablation of Atrial Fibrillation: Prospective Multi-Center Randomized Study.

Background: Both contact force monitoring (CFM) and unipolar signal modification (USM) are guides for ablation, which improve the efficacy of pulmonary vein isolation of atrial fibrillation. We sought to compare the outcomes of atrial fibrillation ablation guided by CFM or USM.

Methods: A total of 136 patients with paroxysmal atrial fibrillation underwent a circumferential pulmonary vein isolation using CF sensing ablation catheters and were randomly assigned to undergo catheter ablation guided by either CFM (CFM-guided group: n=70) or USM (USM-guided group: n=66).

A phase II randomized trial of adjuvant chemotherapy with S-1 versus S-1 plus cisplatin for completely resected pathological stage II/IIIA non-small cell lung cancer.

Objectives: Platinum-based combination chemotherapy is the standard postoperative adjuvant treatment for pathological stage II/III non-small cell lung cancer (NSCLC). Oral S-1 therapy has good efficacy and relatively low toxicity for the treatment of advanced NSCLC. We investigated whether long-term S-1 monotherapy is also useful as an adjuvant therapy after surgery in patients with NSCLC.

Analysis of Dietary Intake during Consecutive-Day Chemotherapy for Bone and Soft-Tissue Sarcomas.

Background: Bone and soft tissue sarcomas are commonly treated with consecutive-day chemotherapy regimens consisting of multiple anticancer agents. Chemotherapy-induced nausea and vomiting (CINV) is a serious adverse effect of these regimens and may result in decreased energy intake during chemotherapy. Decreased energy intake may lead to undernutrition and may cause adverse effects on patient quality of life and survival.

Renal function and urological complications after radical hysterectomy with postoperative radiotherapy and platinum-based chemotherapy for cervical cancer.

Background: We aimed to clarify renal functional changes long term and serious urological complications in women with cervical cancer who undergo radical hysterectomy followed by pelvic radiotherapy and/or platinum-based chemotherapy to treat the initial disease.

Methods: Data on 380 women who underwent radical hysterectomy at the National Kyushu Cancer Center from January 1997 to December 2013 were reviewed. Main outcome measures were the estimated glomerular filtration rate (eGFR) and monitored abnormal urological findings.

Usefulness of semiquantitative PCR-Invader assay for selecting candidates for daclatasvir plus asunaprevir combination therapy among patients with hepatitis C virus genotype 1b.

Aims: PCR-Invader is a highly sensitive assay for detecting non-structural protein 5A (NS5A) resistance-associated variants (RAVs) of hepatitis C virus (HCV). Here, we validated the accuracy of the semiquantitative PCR-Invader (SQ-PI) assay compared to direct sequencing (DS) for identifying NS5A RAVs, and we evaluated the treatment efficacy of daclatasvir plus asunaprevir (DCV + ASV) for patients judged to be non-positive for NS5A RAVs by SQ-PI.

Methods: Detection rates of NS5A RAVs by SQ-PI and DS were compared for 204 patients with HCV genotype 1b.

A randomized phase II study to assess the effect of adjuvant immunotherapy using α-GalCer-pulsed dendritic cells in the patients with completely resected stage II-IIIA non-small cell lung cancer: study protocol for a randomized controlled trial.

Background: As the toxicity associated with the α-GalCer-pulsed dendritic cell (DC) therapy could be considered to be negligible, its addition to postoperative adjuvant chemotherapy would be expected to greatly improve the therapeutic effect, and could result in prolonged survival. The aim of the present study is to compare the therapeutic efficacy of alpha-galactosylceramide-pulsed DC therapy in patients who have undergone a complete resection of stage II-IIIA non-small-cell lung cancer (NSCLC) followed by postoperative adjuvant therapy with cisplatin plus vinorelbine, to that in patients who did not receive additional treatment (surgical resection plus postoperative adjuvant chemotherapy only).

Methods: Subsequent to the complete resection of NSCLC, followed by the administration of cisplatin plus vinorelbine dual-agent combination adjuvant chemotherapy, patients who satisfy the inclusion criteria will be randomly allocated to either the α-GalCer-pulsed DC immune therapy group, or the standard treatment group.
