A Phase II Study for Image Guided Hypofractionated Radiation Boost Therapy for Definitive Treatment of Locally Advanced Cervical Cancer

Summary

Patients enrolled in this study will receive 45 Gy in 25 fractions of intensity modulated external beam radiation therapy. Following the completion of iMRT, patients will receive 28 Gy in 4 fractions using stereotactic body radiation therapy techniques. image Guided Hypofractionated Radiation Treatment boost therapy will be compared to standard of care which consists of standard chemoradiation followed by intracavitary high dose rate brachytherapy.

The study is a prospective single-arm phase ii trial of stereotactic body radiation therapy boost therapy in the definitive treatment of locally advanced cervical cancer. The study will determine whether image Guided Hypofractionated Radiation Treatment boost therapy is efficacious in women with locally advanced cervical cancer without increased risk of acute Gi or Gu toxicity. Study endpoints include local control rate, and , toxicity assessed by CTCaev4

Participant Eligibility

3.1.1 Biopsy proven (LACC) Locally Advanced stage Cervical Cancer (FIGO IB2 x IVB) within 90 days of registration
3.1.2 Zubrod performance status 0-2
3.1.3 Urine or serum pregnancy test for Women of child-bearing potential
3.1.4 Women of child-bearing potential (See note) must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study treatment. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
3.1.5 Patients should have any of the below to be eligible

* Are not candidate for intracavitary brachytherapy due to poor geometry or poor response to external beam RT

* Patients with co-morbid medical conditions, bleeding disorders , poor anesthetic risk precluding brachytherapy

* Patients who refuse brachytherapy

* Patients requiring Interstitial brachytherapy
3.1.6 Patients may be discovered during standard therapy and enrolled prior to boost if they are found to have poor response to standard therapy.
Note: A female of child-bearing potential is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:

* Has not undergone a hysterectomy or bilateral oophorectomy; or

* Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months).
