Experience with primary urethral carcinoma from the blackfoot disease-endemic area of South Taiwan: increased frequency of bulbomembranous adenocarcinoma?
In South Taiwan, there was a high frequency of bulbomembranous urethral adenocarcinoma, which might be associated with chronic arsenic exposure. Although the implications of such an observation are minimal owing to its rarity, it is worth exploring.
The metabolism of 5-FU into its active metabolite 5-FUrd depends on the pH value and can be modulated. 5-FUrd concentrations can be approximately doubled with the intra-aortal application of 5-FU-PEG liposomes compared to free 5-FU.
