Hubungan Ekspresi NFκB dengan Respons Radiasi Kanker Serviks Stadium Lokal Lanjut

One of the expected elimination pathways of cancer cells in the process of radiation is apoptosis. Nuclear factor kappa-B (NFkB) is a transcription factor related to the mechanism of apoptosis resistance of a cell, which can affect the post-radiation response. The aim of this study is to assess the relative expression of NFkB in locally advanced cervical cancer and its relation to radiotherapy response. The study was conducted with observational cohort design on January-October 2015. Pre-radiotherapy cervical biopsy specimen was collected from 17 subjects, while only 10 subjects were willing to be taken mid-radiotherapy cervical biopsy specimen. We extracted and analyzed mRNA of NFkB by using qRT-PCR. NFkB relative expression was tested to its correlation with radiotherapy response. This study demonstrated that median of pra-radiotherapy relative expression on subjects with negative response (0.667; SD 0.413) was higher than positive response (0.315; SD 160.298), but not statistically significant (p=0.578). Alteration of mid-radiotherapy NFkB relative expression compared to pra-radiotherapy showed correlation to radiotherapy response. It is concluded that reduced expression of mid-radiotherapy NFkB relative expression plays a role in increasing radiotherapy response.
