Intervention model description: This is a phase III clinical trial, open, randomized 1: 1, controlled, noninferiority, in a single hospital center. This study will include 140 patients with the diagnosis of malignant tumors of epithelial origin of the cervix.

Patients will be randomized 1: 1 to receive in arm "A" (experimental) to receive concomitant chemotherapy based on gemcitabine at 300 mg / m2 weekly and Arm "B" (control) cisplatin 40 mg / m2 weekly, both arms with RT 50.4 Gy in 5 weeks plus 30Gy brachytherapy at the end of the concomitance.
Primary purpose: TREATMENT

Brief summary: The purpose of this phase III clinical trial, is to evaluate the efficacy and safety of concomitant chemo-radiotherapy with Cisplatin vs Gemcitabine as the first line of treatment in patients with locally advanced cervical cancer, with comorbidities and preserved renal function.

Detailed description: This is a phase III clinical trial, open, randomized 1: 1, controlled, noninferiority, in a single hospital center. This study will include 564 patients with the diagnosis of malignant tumors of epithelial origin of the cervix.

Patients will be randomized 1: 1, arm "A" (experimental) to receive concomitant chemotherapy based on gemcitabine at 300 mg / m2 weekly and Arm "B" (control) to receive cisplatin 40 mg / m2 weekly, both arms with RT 50.4 Gy in 5 weeks plus 30Gy brachytherapy at the end of the concomitance. These patients will be treated in the gynecology-oncology service, candidates for chemo-radiotherapy, it is intended that the recruitment of patients be done in the first 48 months, with a follow-up of 3 years. It is intended to include 3 patients per month, until the total sample is completed in four years. The study is divided into three phases, the first of QT / RT concomitant with gemcitabine or cisplatin depending on the randomized arm; with an approximate duration of 1.5 months with a weekly visit, the second phase is brachytherapy in both arms which lasts from 2 to 7 days, and finally the follow-up phase which lasts for 3 years with a visit every 3 months. In each of the visits we will evaluate the safety of the medication; evaluating adverse events, including laboratory abnormalities as well as acute and chronic toxicity, with the classification according to the common toxicity criteria (CTCAE v4.03) and the efficacy will obtain proportions of clinical and imaging response (TC and / or PET-CT) with the criteria of RECIST v1.1 and / or PERCIST 1.0.

Patient numbers to include. This study will include 140 patients. Test drug, dosage, mode of administration: Gemcitabine at 300 mg / m2 weekly intravenous administration.

Duration of the study 9 years.
