PURPOSE Cisplatin-based chemotherapies are standard treatment regimens of advanced urothelial cell carcinoma. But a significant proportion of patients are unsuitable for cisplatin due to impaired renal function. Carboplatin-based regimens such as gemcitabine and carboplatin regimen (GCb) were applied due to less nephrotoxicity and side effects in these(More)
We report a case of malignant pheochromocytoma recurred after debulking surgery. A 17-year-old male patient visited our hospital for right flank pain. He had not experienced palpitations, headache, sweating or weight loss. Level of urinary catecholamine and its metabolite increased above normal values and abdominal computed tomography showed a huge right(More)
BACKGROUND Currently, percutaneous drainage is the first treatment of choice for hepatic abscesses because of its high success and low mortality rates compared with other surgical procedures. However, percutaneous drainage of hepatic abscesses in the caudate lobe or gastrohepatic space may be difficult. OBJECTIVE The aim of this study was to determine the(More)
Fluorescent nanosized carbon dots (Cdots) are an emerging bioimaging agent with excellent chemical inertness and marginal cytotoxicity in comparison to widely used semiconductor quantum dots. In this work, we report the application of Cdots for real time bioimaging of target specific delivery of hyaluronic acid (HA) derivatives. Polyethylene glycol (PEG)(More)
Optical energy can trigger a variety of photochemical processes useful for therapies. Owing to the shallow penetration of light in tissues, however, the clinical applications of light-activated therapies have been limited. Bioluminescence resonant energy transfer (BRET) may provide a new way of inducing photochemical activation. Here, we show that efficient(More)
BACKGROUND AND STUDY AIMS A diagnostic molecular marker for pre-neoplastic lesions, particularly before polyposis, is still lacking. Lgr5 has been broadly accepted as a marker for intestinal cancer stem cells. The aim of this study was to investigate the monitoring of Lgr5( + ) cells as a useful tool for the early diagnosis of premalignant lesions before(More)
Bile-duct invasion is rare in patients with hepatocellular carcinoma (HCC). We report a case that received peroral direct cholangioscopy (PDCS)-guided endoscopic biopsy and photodynamic treatment (PDT) for recurrent HCC with intraductal tiny nodular tumor growth. A 64-year-old woman presented with recurrent right upper-quadrant pain. Six months previously(More)
Angiogenesis is essential for the progression of cancer, but its involvement in the initial phase of colon tumorigenesis is not well understood. Using intravital endomicroscopy, we visualized the natural history of early pre-tumorous lesions and adenomas in the colon of conditional Apc-knockout and Apc/Kras double mutant mouse models. Early lesions emerged(More)
Ovarian cancer is an intractable disease because patients with ovarian cancer frequently develop drug resistance after long-term chemotherapy. Despite the availability of cumulative information on drug-resistant patients, strategies to reverse drug resistance have still not been established. In this study, we analyzed drug resistance-associated(More)
