Brief Summary:

The current standard for locally advanced cervical cancer is concurrent cisplatin-based chemotherapy, however, the treatment results need to be improved. Epigenetic aberrations play an important role in cancer progression by silencing growth regulatory genes and there is now evidence that inhibitors of DNA methylation and HDAC inhibition synergize the radiation and chemotherapy effects.

Objective. To determine response rate, safety and biological effects of hydralazine and magnesium valproate when added to cisplatin chemoradiation.

Hypothesis. Hydralazine and magnesium valproate associated to chemoradiation will increase the clinical complete response rate to 95% as compared to 75% as seen in historical controls treated with cisplatin chemoradiation in FIGO stage IIIB patients.

Metodology. A total of 17 FIGO stage IIIB patients with histologically confirmed cervical carcinoma with no previous treatment will be included. Patients will be typed for acetylator status and and then receive either 182 or 83 mg of hydralazine, and magnesium valproate at 40mg/Kg from day -7 to the end of chemoradiation (external and brachytherapy). Clinical response rate, safety and transcriptome changes will be analyzed.

Condition or disease Intervention/treatment Phase
Cervical Cancer Drug: Hydralazine and magnesium valproate Procedure: Punch biopsy of the primary tumor Phase 2

Detailed Description:

Eligible patients after signing informed consent will undergo study evaluation and then typed for acetylator phenotype before receive either 182 or 83 mg of hydralazine, and magnesium valproate at 30mg/Kg from day -7 to the end of chemoradiation (external and brachytherapy. External beam radiation will be delivered by megavoltage equipment for a dose of 50gy (2Gy fraction from monday to friday) concurrently with cisplatin at 40mg/m2 for six weeks. Within one to two weeks, intracavitary brachytherapy (low-dose rate, Cesium sources) will be delivered to achieve at least 85Gy to point A. A punch biopsy from the primary tumor will be taken at entering the study and at day 8 of hydralazine and valproate treatment (before the first dose of cisplatin and radiation)to assess global gene expression profiling by microarray analysis. Blood samples will be taken to assess global DNA methylation, histone deacetylase activity and plasma levels of hydralazine and valproic acid.

Clinical response and toxicity will be assessed.
