Overview
Brief Summary
This will be the first study to assess the clinical feasibility of dose escalation with simultaneous integrated boost intensity-modulated radiotherapy for patients with locally advanced cervical cancer. Following screening to confirm eligibility patients will commence a six week treatment period. After this, patients will be followed up by visits to clinic every 3 months for a period of 24 months (2 years). End of study is defined as 24 months after treatment. Patients will be followed up for a minimum of 5 years (as per local policy) after treatment.

Arms & Interventions
Dose escalation study
This is a dose escalation study of IMRT for women with locally advanced cervical cancer. Three dose levels will be investigated, (although, the first dose level is considered to be the equivalent to a standard pelvic dose with parametrial boost). Before moving to the next dose level it must be confirmed by the Chief Investigator that the Maximum Administrable Dose (MAD) has not been met in the previous dose level (see section 6.3). If MAD is reached before dose level 3 the study will stop. All patients enrolled on the study will undergo the same procedures at the same time points, regardless of the dose level they are being given (see section 5).
Intervention: Cisplatin
