Real-world outcomes of FOLFOXIRI plus bevacizumab in patients with metastatic colorectal cancer: the JSCCR-TRIPON study.

Background: FOLFOXIRI plus bevacizumab is a standard first-line chemotherapy for patients with metastatic colorectal cancer (mCRC). However, due to the severe toxicities, this regimen is not widely used. There is limited data on the real-world efficacy and safety.

Acute Dapagliflozin Administration Ameliorates Cardiac Surgery-Associated Acute Kidney Injury in a Rabbit Model.

Background:  Several studies have shown that sodium-glucose cotransporter-2 inhibitors have a renoprotective effect on acute kidney injury (AKI), but their effect on cardiac surgery-associated AKI is unknown.

Methods And Results:  AKI was induced in 25 rabbits without diabetes mellitus by cardiopulmonary bypass (CPB) for 2 h and they were divided into 5 groups: sham; dapagliflozin-treated sham; CPB; dapagliflozin-treated CPB; and furosemide-treated CPB (n=5 in each group). Dapagliflozin was administered via the femoral vein before initiating CPB.

Oncologic investigation of the interval from stent placement to surgery in patients with obstructive colorectal cancer.

Purpose: Self-expandable metallic stent (SEMS) placement is widely used as a bridge to surgery (BTS) procedure for obstructive colorectal cancer. However, evidence regarding the optimal interval between SEMS placement and elective surgery is lacking.

Methods: We retrospectively collected data from patients with BTS between January 2013 and October 2021.

Cannula to Femoral Artery Diameter Ratio Predicts Potential Lower-Limb Ischemia in Minimally Invasive Cardiac Surgery With Femoral Cannulation.

Objective: Lower-limb ischemia is a complication of minimally invasive cardiac surgery with femoral cannulation. Herein, we verified our strategy using distal perfusion cannulation (DPC) against this complication.

Methods: We retrospectively assessed 91 cases of aortic valve replacement with femoral cannulation between January 2019 and March 2023.

A case of attenuated familial adenomatous polyposis in which genetic testing revealed that the children were asymptomatic gene carriers.

Attenuated familial adenomatous polyposis, which accounts for ~10% of familial adenomatous polyposis, is difficult to diagnose because of its milder course and later onset. In both familial adenomatous polyposis and attenuated familial adenomatous polyposis, duodenal cancer is usually recognized 10-20 years after the diagnosis of colonic polyposis. We present herein a 66-year-old man who received pancreaticoduodenectomy due to ampullary carcinoma 17 years before onset of colonic polyposis.

Necrostatin-1 Attenuates Delayed Paraplegia after Transient Spinal Cord Ischemia in Rabbits by Inhibiting the Upregulation of Receptor-Interacting Protein Kinase 1 and 3.

Background: Delayed-onset paraplegia is a disastrous complication after thoracoabdominal aortic open surgery and thoracic endovascular aortic repair. Studies have revealed that transient spinal cord ischemia caused by temporary occlusion of the aorta induces delayed motor neuron death owing to apoptosis and necroptosis. Recently, necrostatin-1 (Nec-1), a necroptosis inhibitor, has been reported to reduce cerebral and myocardial infarction in rats or pigs.

Optimal bowel resection margin in colon cancer surgery: prospective multicentre cohort study with lymph node and feeding artery mapping.

Background: There are no standardised criteria for the 'regional' pericolic node in colon cancer, which represents a major cause of the international uncertainty regarding the optimal bowel resection margin. This study aimed to determine 'regional' pericolic nodes based on prospective lymph node (LN) mapping.

Methods: According to preplanned measurements of the bowel, the anatomical distributions of the feeding artery and LNs were determined in 2996 stages I-III colon cancer patients who underwent colectomy with resection margin >10 cm at 25 institutions in Japan.

The colon inflammatory index score can predict the survival outcome after resection of colorectal cancer: a retrospective multicentre study.

Purpose: Many systemic inflammatory markers have been identified to be prognostic factors in various diseases, including colorectal cancer (CRC). The Colon Inflammatory Index (CII), which is based on the lactate dehydrogenase (LDH) level and the neutrophil-to-lymphocyte ratio (NLR), is reportedly a predictor of the outcome of chemotherapy in patients with metastatic CRC. This retrospective review study aimed to determine whether CII can predict the prognosis after surgical resection of CRC.

Segmental or right hemi-colectomy? The optimal surgical procedure for transverse colon cancer: a propensity score-matched, multicenter, retrospective study.

Purpose: Extended colectomy is sometimes chosen for treatment of transverse colon cancer (TCC) because of concerns about short- and long-term outcomes. However, there is still a lack of evidence regarding the optimal surgical procedure.

Methods: We retrospectively collected and analyzed data of patients who underwent surgical treatment of pathological stage II/III TCC at four hospitals from January 2011 to June 2019.

The T-CEA score: a useful prognostic indicator based on postoperative CEA and pathological T4 levels for patients with stage II-III colorectal cancer.

Purpose: To investigate a prognostic score for stage II-III colorectal cancer (CRC) based on post-CEA and pT4 levels.

Methods: Two cohorts of stage II-III CRC patients who underwent curative surgery between 2011 and 2017 were included. The prognostic score (T-CEA score) was calculated as follows: T-CEA-0, post-CEA ≤ 5 ng/mL and pT1-3; T-CEA-1, post-CEA > 5 ng/mL or pT4; T-CEA-2, post-CEA > 5 ng/mL and pT4.

Analysis of Circulating DNA to Assess Prognoses for Metastatic Colorectal Cancer Patients Treated with Regorafenib Dose-Escalation Therapy: A Retrospective, Exploratory Analysis of the RECC Trial.

Introduction: Regorafenib is a multi-kinase inhibitor approved for patients with metastatic colorectal cancer (mCRC) who were previously treated with standard therapies. A few reports showed the impact of KRAS mutation on therapeutic efficacy of regorafenib. Only one study reported poor prognoses for patients treated with regorafenib who had large amounts of circulating cell-free DNA (cfDNA).

Postoperative infectious complications have a negative oncological impact in patients after stent placement with malignant large bowel obstruction.

Purpose: In this study, we aimed to investigate the oncological impact of postoperative infection in patients with malignant large bowel obstruction managed by self-expandable metallic stent placement as a bridge to surgery.

Methods: The cohort of this multicenter retrospective study comprised 129 patients with pathological stage II/III malignant large bowel obstruction who had undergone bridge to surgery. Patients were allocated to no-postoperative infection (n = 116) and postoperative infection groups (n = 13).

Biomarkers for anti-vascular endothelial growth factor drugs.

Angiogenesis is regulated by interactions between vascular endothelial growth factors (VEGFs) and VEGF receptors. VEGF-A, VEGF-D, placental growth factor (PlGF) and plasminogen activator inhibitor-1 (PAI-1) have tumor angiogenic activity. VEGF-A and PAI-1 levels in the blood may impact the activity of bevacizumab, and VEGF-D levels may similarly diminish the efficacy of ramucirumab.

Endovascular therapy for intracranial infectious aneurysms associated with a left ventricular assist device: illustrative case.

Background: Cerebrovascular events and infection are among the most common complications of left ventricular assist device (LVAD) therapy. The authors reported on a patient with an infectious intracranial aneurysm (IIA) associated with LVAD infection that was successfully occluded by endovascular therapy.

Observations: A 37-year-old man with severe heart failure received an implantable LVAD.

A case of mediastinal abscess and infected aortic aneurysm caused by dissemination of Mycobacterium abscessus subsp. massiliense pulmonary disease.

An 81-year-old man was admitted to our hospital because of fever and malaise that had persisted for 3 months. The patient had undergone two aortic valve replacements, 10 and 5 years previously, because of aortic valve regurgitation and infectious endocarditis. He also had had asymptomatic Mycobacterium abscessus complex (MABC) pulmonary disease for the two previous years.
