Impaired Consciousness Due to Hyperammonemia During S-1 Administration for Unresectable Pancreatic Cancer.

A 71-year-old woman diagnosed with unresectable locally advanced pancreatic cancer was initially treated with gemcitabine and nab-paclitaxel as first-line therapy. The tumor exhibited no significant progression; however, after 12 cycles, the patient developed drug-induced interstitial pneumonia, leading to the discontinuation of gemcitabine and nab-paclitaxel therapy. Following recovery from pneumonia, S-1 therapy was initiated as second-line treatment.

The clinical outcomes of combination chemotherapy in elderly patients with advanced biliary tract cancer: an exploratory analysis of JCOG1113.

In the FUGA-BT trial (JCOG1113), gemcitabine plus S-1 (GS) showed non-inferiority to gemcitabine plus cisplatin (GC) in overall survival (OS) with good tolerance for patients with advanced biliary tract cancer (BTC). We performed a subgroup analysis focused on the elderly cohort of this trial. All 354 enrolled patients in JCOG1113 were classify into two groups; < 75 (non-elderly) and ≥ 75 years (elderly) group.

Phase II study of S-1 and oxaliplatin as neoadjuvant chemotherapy for locally advanced adenocarcinoma of the gastric or esophagogastric junction: KSCC1601.

Background: Perioperative chemotherapy is the standard of care for locally advanced gastric cancer (LAGC). This phase II study investigated the efficacy and safety of S-1 and oxaliplatin (SOX) as neoadjuvant chemotherapy (NAC) for LAGC and esophagogastric junction cancer (EGJC).

Methods: Patients completed up to three cycles of SOX (oxaliplatin 130 mg/m on day 1, oral S-1 40-60 mg twice daily for 2 weeks every 3 weeks), followed by gastrectomy and D2 lymphadenectomy.

Comparison of gemcitabine-based chemotherapies for advanced biliary tract cancers by renal function: an exploratory analysis of JCOG1113.

JCOG1113 is a randomized phase III trial in patients with advanced biliary tract cancers (BTCs) (UMIN000001685), and gemcitabine plus S-1 (GS) was not inferior to gemcitabine plus cisplatin (GC). However, poor renal function often results in high toxicity of S-1. Therefore, we examined whether GS can be recommended for patients with low creatinine clearance (CCr).

Clinical features of immune-mediated hepatotoxicity induced by immune checkpoint inhibitors in patients with cancers.

Purpose: The risk factors and clinical characteristics of ICI-induced immune-mediated hepatotoxicity (IMH) are not fully understood. Thus, the present study sought to clarify the clinical features of IMH.

Methods: All patients treated with ICIs between September 2014 and April 2019 at our institution were included.

Randomized phase II study of chemoradiotherapy with versus without induction chemotherapy for locally advanced pancreatic cancer: Japan Clinical Oncology Group trial, JCOG1106.

Background: Chemoradiotherapy is a treatment option for locally advanced pancreatic cancer. However, the efficacy of induction chemotherapy prior to chemoradiotherapy is uncertain. The aim of this randomized, multicentre phase II study is to evaluate the efficacy and safety of chemoradiotherapy with and without induction chemotherapy to determine the significance of induction chemotherapy.

Phase 1 study of Gemcitabine/Nab-paclitaxel/S-1 in patients with unresectable pancreatic cancer (GeNeS1S trial).

Purpose: We conducted a phase 1 study to determine the maximum tolerated dose and the recommended dose of gemcitabine/nab-paclitaxel/S-1 combination chemotherapy in patients with unresectable pancreatic cancer.

Methods: We enrolled patients aged 20 years or older with unresectable pancreatic cancer and who had not been treated with chemotherapy or radiation therapy. Gemcitabine and nab-paclitaxel were administered on days 1 and 8, and S-1 was administered orally twice daily for 2 weeks, repeated every 3 weeks.

Phase II clinical trial of gemcitabine plus oxaliplatin in patients with metastatic pancreatic adenocarcinoma with a family history of pancreatic/breast/ovarian/prostate cancer or personal history of breast/ovarian/prostate cancer (FABRIC study).

Background: A family/personal history of breast, ovarian, or pancreatic cancer is a useful predictive marker for response to platinum-based chemotherapy in treating patients with pancreatic cancer. These cancers, and prostate cancer, are known as BRCA-related malignancies. We evaluated the efficacy of gemcitabine plus oxaliplatin (GEMOX) in patients with metastatic pancreatic cancer with a family/personal history of these cancers.

Combination gemcitabine plus S-1 versus gemcitabine plus cisplatin for advanced/recurrent biliary tract cancer: the FUGA-BT (JCOG1113) randomized phase III clinical trial.

Background: Gemcitabine plus cisplatin (GC) is the standard treatment of advanced biliary tract cancer (BTC); however, it causes nausea, vomiting, and anorexia, and requires hydration. Gemcitabine plus S-1 (GS) reportedly has equal to, or better, efficacy and an acceptable toxicity profile. We aimed to confirm the non-inferiority of GS to GC for patients with advanced/recurrent BTC in terms of overall survival (OS).

Adapalene Gel 0.1% Versus Placebo as Prophylaxis for Anti-Epidermal Growth Factor Receptor-Induced Acne-Like Rash: A Randomized Left-Right Comparative Evaluation (APPEARANCE).

Lessons Learned: The results of the APPEARANCE trial indicate that adapalene does not prevent acne-like rash over placebo when added to topical moisturizer and oral minocycline but instead may have a detrimental effect. Therefore, adapalene is not recommended as prophylaxis against acne-like rash induced by anti-epidermal growth factor receptor therapies.Given that acne-like rash was completely controlled with placebo in approximately half of patients, predictive measures to identify patients needing intensive prophylaxis are required.

Short-Term and Long-Term Outcomes of Infliximab and Tacrolimus Treatment for Moderate to Severe Ulcerative Colitis: Retrospective Observational Study.

Background/aims: While some studies have shown that IFX and TAC exhibit similar efficacy against UC in the short-term, it is unclear which drug produces better long-term outcomes. In this study, we compared the long-term efficacy of IFX and TAC in patients with moderate to severe UC.

Methods: This retrospective study was conducted from 2009 to 2017.

Constrictive pericarditis caused by a pericardial-occupying tumor due to esophageal cancer.

A 61-year-old female was admitted to our hospital for esophageal cancer treatment. Esophagectomy with 2-field lymphadenectomy was performed. Postoperative findings revealed the lesion was a poorly differentiated squamous cell carcinoma invading into the diaphragm and there were no carcinoma cells on the surgical margins.

Polypoid leiomyosarcoma of the esophagus treated by endoscopic submucosal dissection.

We report a rare case of polypoid leiomyosarcoma of the esophagus that was treated by endoscopic submucosal dissection (ESD). A 63-year-old man with complaints of progressive dysphagia was referred to Hyogo Cancer Center for treatment of esophageal tumor. Esophagoscopy revealed a polypoid tumor 25 mm in diameter on the left side of the upper esophagus.

Multicenter retrospective analysis of systemic chemotherapy for advanced neuroendocrine carcinoma of the digestive system.

This study analyzed outcomes of systemic chemotherapy for advanced neuroendocrine carcinoma (NEC) of the digestive system. Clinical data from 258 patients with unresectable or recurrent NEC of the gastrointestinal tract (GI) or hepato-biliary-pancreatic system (HBP), who received chemotherapy, were collected from 23 Japanese institutions and analyzed retrospectively. Patients had primary sites in the esophagus (n = 85), stomach (n = 70), small bowel (n = 6), colorectum (n = 31), hepato-biliary system (n = 31) and pancreas (n = 31).

Muscle-specific overexpression of heparin-binding epidermal growth factor-like growth factor increases peripheral glucose disposal and insulin sensitivity.

Physical exercise ameliorates metabolic disorders such as type 2 diabetes mellitus and obesity, but the molecular basis of these effects remains elusive. In the present study, we found that exercise up-regulates heparin-binding epidermal growth factor-like growth factor (HB-EGF) in skeletal muscle. To address the metabolic consequences of such gain of HB-EGF function, we generated mice that overexpress this protein specifically in muscle.

Overexpression of the transcriptional coregulator Cited2 protects against glucocorticoid-induced atrophy of C2C12 myotubes.

In patients with various catabolic conditions, glucocorticoid excess induces skeletal muscle wasting by accelerating protein degradation via the ubiquitin-proteasome pathway. Although the transcriptional coactivator p300 has been implicated in this pathological process, regulatory mechanisms and molecular targets of its action remain unclear. Here we show that CREB-binding protein (CBP)/p300-interacting transactivator with ED-rich tail 2 (Cited2), which binds to the cysteine-histidine-rich region 1 of p300 and CBP, regulates muscle mass in vitro.

Insulin-induced GLUT4 movements in C2C12 myoblasts: evidence against a role of conventional kinesin motor proteins.

Insulin induces translocation of the glucose transporter GLUT4 from intracellular storage compartment to the plasma membrane via complex mechanisms that require intact cytoskeletal networks. In cultured adipocytes, conventional kinesin motor proteins have been proposed to mediate GLUT4 movements on microtubules. It remains, however, unclear whether kinesin motor system plays a similar regulatory role in myocytes.

Dok1 mediates high-fat diet-induced adipocyte hypertrophy and obesity through modulation of PPAR-gamma phosphorylation.

Insulin receptor substrate (IRS)-1 and IRS-2 have dominant roles in the action of insulin, but other substrates of the insulin receptor kinase, such as Gab1, c-Cbl, SH2-B and APS, are also of physiological relevance. Although the protein downstream of tyrosine kinases-1 (Dok1) is known to function as a multisite adapter molecule in insulin signaling, its role in energy homeostasis has remained unclear. Here we show that Dok1 regulates adiposity.
