About

This randomized phase III trial studies radiation therapy with chemotherapy to see how well they work compared to radiation therapy alone in treating patients with stage I-IIA cervical cancer who previously underwent surgery. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving radiation therapy together with chemotherapy is more effective than radiation therapy alone in treating patients with cervical cancer.

Full description

PRIMARY OBJECTIVE:

I. To determine if post-operative adjuvant chemo-radiation therapy (CRT) can significantly improve recurrence-free survival (RFS) when compared to radiation therapy (RT) alone in stage I-IIA cervical cancer patients with intermediate-risk factors after treatment with radical hysterectomy.

SECONDARY OBJECTIVES:

I. To determine whether post-operative adjuvant CRT can improve overall survival (OS) when compared to RT alone in stage I-IIA cervical cancer patients with intermediate risk factors after treatment with radical hysterectomy.

II. To assess differences (across treatment arms) in incidence and severity of therapy attributed adverse events utilizing the active version of Common Terminology Criteria for Adverse Events (CTCAE).

III. To provide assessment of patient risk version (vs) benefit (positive study only).

QUALITY OF LIFE OBJECTIVE:

I. To determine whether post-operative adjuvant CRT improves the health-related quality-of-life (QOL) (compared to RT alone) as measured by Functional Assessment of Cancer Therapy-Cervix (FACT-Cx) Trial Outcome Index (TOI) and produce favorable toxicity profiles (with particular focus on treatment related genitourinary, gastrointestinal, neurological, pain and sexual adverse events).

TRANSLATIONAL RESEARCH OBJECTIVES:

I. To bank archival tumor tissue for research studies, including studies that evaluate the association between biomarkers, RFS, OS, and clinical-surgical-pathologic characteristics in patients randomized to post-operative adjuvant CRT compared to RT alone.

II. To bank deoxyribonucleic acid (DNA) from whole blood for research studies, including studies that evaluate associations between single nucleotide polymorphisms (SNPs), and measures of clinical outcome, including RFS, OS, and adverse events in patients randomized to post-operative adjuvant CRT compared to RT alone.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients undergo pelvic external-beam radiation therapy (EBRT) or intensity-modulated radiation therapy (IMRT) 5 days a week for 5.5 weeks.

ARM II: Patients receive cisplatin IV over 1-2 hours on day 1 and undergo radiotherapy as in Arm I. Treatment with cisplatin repeats every 7 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed up every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.
