DNA damage and oncogenic viruses increase the risk of cancer post-kidney transplantation, including skin cancer, Kaposi's sarcoma, oral cancer, and non-Hodgkin lymphoma. Here we report an uncommon case of liver angiosarcoma that occurred 8 years after kidney transplantation. This study strictly complied with the Helsinki Congress and the Istanbul Declaration regarding donor source.A 57-year-old female patient received a cadaver kidney transplantation 8 years ago. She followed a long-term regimen of tacrolimus, mycophenolate sodium, and everolimus, with good renal function. She received annual regular abdominal ultrasound examinations after kidney transplantation, which showed no findings. The patient suffered from several symptoms for approximately 2 weeks before a scheduled abdominal ultrasound: diarrhea, epigastric pain, abdominal fullness, tea-colored urine, and little stool passage. The abdominal computerized tomography showed multiple hepatic tumors in both the hepatic lobes with engorged vasculatures and mild hemoperitoneum. A liver biopsy revealed the histopathology of angiosarcoma. The patient suffered multiple organ failure within one month of treatment.Various post-transplant malignancies are not uncommon after transplantation, warranting periodic screenings for any symptoms in these patients.

In this study, UV/H2O2 treatment was used to evaluate its efficacy for control of natural organic matter (NOM) in different water sources in Taiwan and the results were compared with the conventional water treatment process. The NOM fractions analysis showed that compositions of NOM could be very different between the various water sources, and the raw water quality in Kin-Men (an off shore island of Taiwan) was characteristic when compared to other water sources. Raw water taken from Kin-Men generally had high dissolved organic carbon (DOC) concentrations and ~ 50% of the NOM in the raw water was hydrophilic. After UV/H2O2 treatment, a portion of the hydrophobic fractions of NOM in raw waters were transformed into hydrophilic ones. In conventional water treatment process, coagulation and slow filtration treatments have better efficiency to reduce the NOM in water especially for the hydrophobic portion. However, the pre-chlorination treatment for raw water increased the DOC concentration due to the lysis of algae cells. This study concluded that hydrophobic acids portion is the most sensitive portion of NOM to UV/H2O2 and conventional treatment processes. Trihalomethanes formation potential (THMFP) tests showed that hydrophobic acids portion is also the main contributor to THMs formation after chlorination process.
