Pharmacokinetic evaluation of gemcitabine hydrochloride for the treatment of cervical cancer

Abstract

Introduction: Cervical cancer is the third most prevalent cancer in females worldwide. When advanced, the disease requires primary radiation concurrent with chemotherapy. However, chemotherapy alone is the standard treatment for recurrent/persistent/metastatic disease.Areas covered: Areas covered in this review include the treatment of advanced cervical cancer with gemcitabine as radiosensitizer, either alone or in combination with cisplatin. The use of gemcitabine for recurrent/persistent/metastatic cervical cancer is also reviewed.Expert opinion: Statistically significantly better survival rates are achieved with cisplatin doublets against cisplatin alone, in the management of recurrent/persistent/metastatic cervical cancer. The choice of the cisplatin doublet with paclitaxel, vinorelbine, gemcitabine and topotecan arms should be based on physician preference, pre-existing morbidity and patient-related factors. In advanced disease, a recently reported Phase III trial establishes the novel regimen of concurrent gemcitabine plus cisplatin and external radiation, followed by brachytherapy and two adjuvant 21-day cycles of gemcitabine plus cisplatin, as significantly improving survival outcomes when compared with the current standard of care. The increased acute toxicity of this regimen is clear; however, this should not deter its incorporation into clinical practice, in that the toxicity is predictable and manageable; nevertheless, the occurrence of late toxicity and survival at longer follow-up time are reasonable concerns in this regimen.
