The Relationship Between Expression of HIF-1α and Clinical Response in Cervical Cancer Patients with Neoadjuvant Chemotherapy at Dr. Soetomo Surabaya Hospital

Abstract

This investigation aims to analyze the relationship between expression of Hypoxia Inducible factors-1 αlfa (HIF-1α) to assess the response to neoadjuvant chemotherapy in cervical cancer patients. This research is a Quast Experimental Non-Randomized Before and After with no control design with a sample size of 30 stage IIIB cervical cancer patients by inclusion and exclusion criteria, with pretest and posttest treatment, namely biopsy for immunohistochemical examination and abdominal ultrasound to evaluate lesion diameter cervix after three cycles of chemotherapy. This study showed a decrease in HIF-1α expression before and after chemotherapy (p=0,003) and a decrease in the diameter of cervical lesions before and after chemotherapy (p=0,000). Correlation between decreased HIF-1α expression and decreased diameter of cervical lesions (p=<0,05). Response to neoadjuvant chemotherapy: 25 patients (83,3 %) showed a negative response and 5 patients (16,7 %) showed a positive response. Strong HIF-1α expression before chemotherapy gave a negative response 23 and 25 subjects with a negative response after neoadjuvant chemotherapy. This study found a relationship between high HIF-α expression before chemotherapy with a negative chemotherapy response and low HIF-1α expression after neoadjuvant chemotherapy with a positive chemotherapy response in cervical cancer patients at Dr Soetomo Hospital, Surabaya
