Association Between Dose and Duration of Cisplatin Exposure with Cytotoxicity Effect on Nasopharyngeal Carcinoma Stem Cell

Abstract

Nasopharyngeal carcinoma (NPC) is ranked 6th of malignant tumors in Indonesia. To analyze the correlation of dose and duration of cisplatin exposure with cytotoxic effects on nasopharyngeal carcinoma stem cells. The biopsy NPC tissue was cultured and processed to obtain NPC stem cells to be treated with cisplatin different doses and durations (24 and 48 h). The number of dead cells after exposure will be calculated using a hemocytometer. Death stem cell density of NPC at exposure of 2 μg/ml cisplatin dose was 81.37%, while the smallest death cell density a dose of 0.05 μg/ml after a 72-h observation was 21.3%. The coefficient correlation 0.827 and value p = 0.000 (p < 0.05). The analysis of the correlation between cisplatin exposure duration and death cell was also significant with the correlation coefficient − 0.357 and the value p = 0.001 (p < 0.05). There was a correlation between the increased dose of cisplatin with the cytotoxicity effects on NPC stem cell.
