We have reported loss of SMAD4 promotes expression CCL15 from colorectal cancer to recruit CCR1+ myeloid cells through the CCL15-CCR1 axis, which contributes invasion and liver metastasis. However, molecular mechanism lung metastasis is yet be elucidated. Our purpose determine whether similar involved in cancer.In a mouse model, we examined could affect metastatic activity axis. immunohistochemically analyzed SMAD4, CCL15, CCR1 with 107 clinical specimens metastases. also characterized using...

Three-dimensional computed tomography (3D-CT) technologies have been developed and refined over time. Recently, high-speed high-quality 3D-CT also introduced to the field of thoracic surgery. The purpose this manuscript is demonstrate several examples these in various scenarios surgery.A newly-developed 3D image analysis software system was used Kyoto University Hospital. Simulation and/or navigation were performed using technology surgeries.Preoperative simulation most patients undergoing...

Abstract Lung cancer treatment is difficult owing to chemoresistance. Hypoxia‐inducible factor 1 ( HIF ‐1) and ‐1‐induced glycolysis are correlated with chemoresistance; however, this not evident in lung cancer. We investigated the effect of ‐1 α carbonic anhydrase IX CAIX ), a transmembrane protein neutralizing intracellular acidosis, on chemoresistance prognosis patients after induction chemoradiotherapy. Associations , glucose transporter GLUT 1), were using A549 cells under normoxia or...

Malignant pleural mesothelioma (MPM) has extremely limited treatment despite a poor prognosis. Moreover, molecular targeted therapy for MPM not yet been implemented; thus, new is highly desirable. Near-infrared photoimmunotherapy (NIR-PIT) recently developed cancer that combines the specificity of antibodies targeting tumors with toxicity induced by photoabsorber after exposure to NIR-light. In this study, we phototherapy podoplanin (PDPN) use both NIR-PIT and an anti-PDPN antibody, NZ-1. An...

BackgroundSmall cell lung cancer (SCLC) has a poor prognosis, and its treatment options are limited. Delta-like protein 3 (DLL3) is expressed specifically in SCLC considered promising therapeutic target for patients with this disease. Rovalpituzumab tesirine (Rova-T) was the first antibody-drug conjugate targeting DLL3. Although Rova-T development unfortunately terminated, DLL3 remains an ideal SCLC. Near infrared photoimmunotherapy (NIR-PIT) new form of that employs antibody-photosensitiser...

Cancer-associated fibroblasts (CAFs) are an integral component of the tumor microenvironment (TME). Most CAFs shape TME toward immunosuppressive milieu and attenuate efficacy immune checkpoint blockade (ICB) therapy. However, detailed mechanism how heterogeneous regulate response to ICB therapy has not been defined. Here, we show that a recently defined CAF subset characterized by expression Meflin, glycosylphosphatidylinositol-anchored protein marker mesenchymal stromal/stem cells, is...

Abstract Objectives Chest wall infiltration in primary lung cancer affects the surgical and therapeutic strategies. This study evaluates efficacy of chest vessel involvement subpleural (CWVI) on ultra-high-resolution CT (UHR-CT) for detecting invasion. Materials methods A retrospective analysis cases with confirmed pleural invasion was conducted from November 2019 to April 2022 . Seventy-seven patients (mean ± standard deviation age 70 8 years, 64 males) who underwent preoperative...

There are few papers on three-dimensional (3D) images of the lungs using non-enhanced computed tomography (CT). This study aimed to investigate accuracy 3D CT. The included 10 consecutive cases for each lung lobe, totalling 50 between March and December 2022. patients had both contrast-enhanced CT taken within 2 months before surgery. A image analysis system (SYNAPSE VINCENT) was used obtain pulmonary artery (PA), vein (PV), bronchus (Br). automatically generated based CTs, which were then...

Peripheral helper T (Tph) cells, together with plasma are the major pathogenic lymphocytes in synovium rheumatoid arthritis (RA). However, whether these cells involved RA-associated lung and/or airway disease is unknown. Tph sputum were analyzed by flow cytometry and compared those synovial fluid tissue. Forty RA subjects for whom induced could be collected along several clinical parameters; severity was assessed using Disease Activity Score 28 joints (DAS28). Lung chest computed tomography...

The aim of the study was to describe specific characteristics patients with microscopic residual disease (R1) after surgical resection for non-small cell lung cancer and evaluate effect postoperative therapy in R1 patients. We retrospectively reviewed clinical data 3,296 Enrolled were divided into two groups: those who received (PT) did not receive (NPT). A total 52 enrolled. Of those, 27 (51.9%) underwent extended resections addition standard surgery, 37 assigned PT group 15 NPT group....

ABSTRACT In cases of thymoma with autoimmune disease, extended thymectomy may improve disease symptoms and medication effects. Myasthenia gravis (MG) is the most common complication, but Stiff‐Person syndrome (SPS) rare, there are few reports surgery. present case, we performed robot‐assisted on a 74‐year‐old man who had MG SPS. At 6 months after surgery, his SPS improved dose prednisolone been reduced, confirming that surgical treatment contributed to control. Thus far, only two studies...

Mesothelioma is characterized by the inactivation of tumor suppressor genes, with frequent mutations in neurofibromin 2 (NF2), BRCA1-associated protein 1 (BAP1), and cyclin-dependent kinase inhibitor 2A (CDKN2A). These lead to disruptions Hippo signaling pathway histone methylation, promoting growth. NF2 result Merlin loss, leading uncontrolled cell proliferation, whereas BAP1 impair chromatin remodeling hinder DNA damage repair. Emerging molecular targets mesothelioma include mesothelin...
