Abstract

Giving neoadjuvant chemotherapy allows stage IIB cervical cancer having surgery with a chance of avoiding radiotherapy. Giving neoadjuvant chemotherapy in several studies produces varied responsses. The method for predicting whether a cervical cancer patient experiences responsse of treatment in neoadjuvant chemotherapy becomes important thing, considering the side effects of chemotherapy, time, and cost. Sub-population of cells called Cancer Stem Cells (CSC) is something which is alleged to be responssible for cancer growth, recurrence and the process of resistance to chemotherapy and radiation. Some researchers proved that this occurrence is due to the cancer stem cell which is surviving after chemotherapy. The presence of cervical cancer stem cells is shown by CD44 and ALDH1. This research proves there is connection between the expression of CD44 and ALDH1 as a marker of cancer stem cells with cisplatin neoadjuvant chemotherapy responsse and correlation in the increasing of expression of CD44 and ALDH1 (a marker of cancer stem cells) against cisplatin neoadjuvant chemotherapy resistance in cervical cancer stage IIB. Design observational analytic form prospectively study with total samples 30 patient cervical cancer IIB from December 2016 until May 2017. Clinical and MRI examination and cervical biopsy to immunohistochemistry examination for CD44 and ALDH1. Administration of neoadjuvant chemotherapy (NAC) cisplatin 50 mg/m2 4 times everyweek. After 2–3 weeks after last NAC, repeat to MRI examination. Assesment responsse therapy with RECIST criteria. Chemotherapy responsse obtained Partial Responsse (PR) 12 pts (40%), Stable Dissease (SD) 12 pts (40%), and Progressive Dissease (PD) 6 pts (20%). There is Relationship Strong Negative Correlation Expression CD44 with chemotherapy responsse (Spearman test rs= - 0.903 and p= 0.000); analysis ROC curve obtained cut off 37.00 and 76.00 with accuration 86,67%. Also there is Relationship Strong Negative Correlation Expression ALDH1 with chemotherapy responsse (Spearman test rs= - 0.893 and p= 0.000); analysis ROC curve obtained cut off 55.00 and 94.00 with accuration 93.33%. Analysis with Spearman there is Strong Correlation between CD44 with ALDH1 (rs= 0.907 and p=0.000). And ALDH1 is more better predictor than CD44 to predict chemoterapy responsse (beta coeficient CD44 = -0.389, ALDH1= -0.551). CD44 and ALDH1 expression can be used a predictor of responsse to neoadjuvant chemotherapy cisplatin in patient with cervical cancer IIB; and ALDH1 more better as predictor than CD44.
