* Patients with histological diagnosis of persistent/recurrent cervical cancer, local and/or systemic, with disease measurable by physical examination and TAC. REQUIRED confirmation by biopsy of the recurrence or, persistence only if: lesion is single, less than 2 cm and/or has no sharp edges.
* Chemo-radiotherapy to pelvis or pelvis plus extended fields (may have received concomitant chemotherapy as a radiosensitizer) provided it is within 90 days from the last application and the secondary radiation acute effects have disappeared.

* Leukocytes greater or equal to 4000/mm3.
* Platelets equal or greater to 100 000 mm3.
* Hepatic: Total bilirubin up to 1.5 times normal value, albumin equal or greater to 2: alanine aminotransferase (ALT) and aspartate aminotransferase (AST) lower or equal to 2.5 times the regular superior limit.
* Renal: Normal creatinine. If high, the extent debugging must be greater than 60 mL/min.
* With the exception of alopecia, patients should have resolution of all acute toxic effects of any prior surgery, radiotherapy or chemotherapy, such effects qualified according to the Common Toxicity Criteria (CTC version 3.0) from the National Cancer Institute (NCI), or within the limits shown in laboratory parameters mentioned above.
* Be willing and able to comply with the programmed visits, the treatment plan and laboratory tests.
* The ability to understand the nature of the study and give a report written consent.

* Use of any of the research agents in the month prior to enrollment in this study.
* Serious concomitant systemic disorders incompatible with the study at the discretion of the investigator.
* Recently receiving another onco-specific treatment research.
* The recently or previously diagnosed hypertension and controlled with any antihypertensive or a combination of them (provided that they do not include hydralazine) WON'T be an exclusion criteria.

* If there is evidence of disease progression.
* Unacceptable toxicity.
* If the clinician considers that a change of therapy will be for the best interest of the patient.
