Cancer of the Cervix, Cervical Neoplasms
Conditions
Brief summary
The purpose of this study is to determine the maximum tolerated dose of integrated boost radiation therapy when given with concurrent chemotherapy (cisplatin).
Interventions
Many studies have utilized a sequential boost to deliver a total dose of 55 - 60 Gy to the pelvic sidewall (covering the lower pelvic lymph nodes), including 8-10 Gy that is usually delivered with brachytherapy (1-3). This study treatment plan will escalate the dose to pelvic and para-aortic nodal disease from 60 Gy in 2.4 Gy per fraction to 70Gy in 2.8 Gy per fraction in 3 dose cohorts, using an integrated boost technique utilizing the same number of fractions for all cohorts (25 fractions) while the elective volumes are held constant at 45Gy

| Maximum Tolerated Dose of Integrated Boost Radiation Therapy, Administered With IMRT Technique With Concurrent Chemotherapy (Cisplatin). | During RT to 6 weeks post RT | Concurrent radiation therapy and chemotherapy is the standard of care for node positive cervical cancer. While there are several acceptable means to boost the disease in the low pelvis (i.e. brachytherapy, IMRT, or external beam), there is limited research into boosting gross disease in the pelvis or para-aortic region. This protocol is designed to determine the maximum tolerated dose of treating tumor bearing regions within the abdomen and pelvis, using an integrated boost technique and concurrent chemotherapy. |
