Inflammatory myofibroblastic tumor (IMT), a rare sarcoma, is primarily treated via resection of the mass. However, in cases recurrence or unresectable tumors, no standard care exists. While crizotinib, an anaplastic lymphoma kinase (ALK) inhibitor, only approved for non-small-cell lung cancer with ALK mutation, it reportedly effective other malignant tumors mutation. We herein report case involving 37-year-old woman retroperitoneal IMT who experienced after complete resection, whom...

Regorafenib (REG) and trifluridine/tipiracil (FTD/TPI) showed survival benefits in metastatic colorectal cancer patients previously treated with standard chemotherapies; therefore, we compared the efficacy safety of these two treatments. Patients REG or FTD/TPI as a salvage-line therapy from May 2014 to December 2017 were included. We retrospectively analyzed long-term survival, safety, clinical outcomes. Among 134 patients, 57 77 received FTD/TPI, respectively. The group more prior systemic...

Abstract Background Trastuzumab emtansine (T-DM1) treatment for human epidermal growth factor receptor-2 (HER2)-positive metastatic breast cancer after taxane with trastuzumab and pertuzumab is standard therapy. However, strategies beyond T-DM1 are still in development insufficient evidence of their effectiveness. Here, we aimed to evaluate real-world choice efficacy treatments HER2-positive cancer. Methods In this multi-centre retrospective cohort study involving 17 hospitals, 325 female...

FOLFOXIRI plus bevacizumab has a promising efficacy as first-line systemic chemotherapy for metastatic colorectal cancer (mCRC). This study aimed to evaluate the safety and effectiveness of antibodies.Fifty-five patients were enrolled (median age: 60 years, males: 25, females: 30). Twenty-six subjects had RAS mutations 29 wild-type. Anti-VEGF anti-EGFR antibodies administered 38 17 patients, respectively. The most common severe adverse event was neutropenia (51%). overall response rate (ORR)...

Nowadays many types of pipe such as water pipes, drain and gas are underground. Also pipeline used in places where people cannot enter, atomic power plants chemical plants. Maintenance these pipes pipelines is an important issue to keep our social life safe comfortable. Some maintenance robots have already been developed; but all for medium or large sizes. No robots, which small size with inner diameter one inch less, developed. The authors thus trying develop a screw-principle microrobot,...

Background/Aim: Although direct oral anti - coagulants (DOACs) are as safe and effective conventional anticoagulants for treating venous thromboembolism (VTE), we have insufficient evidence justifying their use in patients with active cancer. We investigated the safety effectiveness of DOACs Patients Methods: To investigate efficacy DOACs, retrospectively extracted 312 consecutive cancer who were prescribed edoxaban, rivaroxaban or apixaban VTE. Results: The most common primary sites lung,...

Erlotinib plus gemcitabine is one of the standard chemotherapies for unresectable pancreatic cancer. Pancreatic cancer has highest frequency KRAS gene mutations among human cancers, and some studies suggest that status might be a predictive biomarker anti-epidermal growth factor receptor treatment. However, reliability this not been confirmed. Here, we evaluated impact in patients treated with first line gemcitabine-based chemotherapy. 23 chemotherapy whose could examined from primary or...
