Gestational trophoblastic neoplasia coexisting with cervical carcinoma: A case report / Philippine Journal of Obstetrics and Gynecology

@#Gestational trophoblastic neoplasia (GTN) with a concurrent cervical malignancy is very rare, making the case both a diagnostic dilemma and a therapeutic challenge. Currently, there has only been one reported case worldwide. We present a case of GTN Stage I:11 with non‑keratinizing squamous cell carcinoma of the cervix Stage II‑B. Initial treatment, in the form of chemotherapy, was directed toward the GTN, as this appeared to be the more aggressive disease. Surgery was not feasible during diagnosis due to the cervical carcinoma. However, the GTN proved resistant to chemotherapy due to the increasing beta human chorionic gonadotropin titers. An attempt to decrease the size of the cervix for surgery to be possible through chemoradiation was instituted, but due to complications and tumor progression to the lungs, she succumbed to the malignancy.

Beta-human chorionic Gonadotropin levels as early predictor for progression to Gestational Trophoblastic Neoplasia after molar pregnancy evacuation at a Philippine tertiary hospital / Philippine Journal of Obstetrics and Gynecology

Objective@#This study aimed to determine if the beta-human chorionic gonadotropin (hCG) levels during the first 5 weeks after a molar evacuation predict progression to gestational trophoblastic neoplasia (GTN).@*Materials and Methods@#This was a retrospective cohort study of complete mole cases managed at a Philippine tertiary hospital from January 2009 to December 2018. Extracted data were analyzed using applicable statistical tools. The level of significance was set at a P < 0.05 using two-tailed comparisons. @*Results@#One hundred and fifty-five complete patient records were available for review. Disease progression in 15.48% of cases while regression in 84.52% were noted. Uterine size was larger in those who eventually had postmolar GTN (t: −3.12, df: 32.64, P: 0.01). Analysis of the receiver operating characteristic curve showed that optimum cut-off levels for predicting GTN at 1, 3, and 5 weeks after evacuation were 4,152 mIU/ml (sensitivity: 50%, specificity: 94.7%, area under the curve [AUC]: 0.75), 804 mIU/ml (sensitivity: 62.5, specificity: 96.9%, AUC: 0.94), and 541 mIU/ml (70.8%, specificity: 97.7%, AUC: 0.96), respectively. @*Conclusion@#The level of hCG within the first 5 weeks after molar pregnancy evacuation is predictive of progression to GTN.
