Pelvic Radiation Therapy or Vaginal Implant Radiation Therapy, Paclitaxel, and Carboplatin in Treating Patients With High-Risk Stage I or Stage II Endometrial Cancer
Trial ID or NCT#
This randomized phase III trial studies pelvic radiation therapy to see how well it works compared with vaginal implant radiation therapy, paclitaxel, and carboplatin in treating patients with high-risk stage I or stage II endometrial cancer. Radiation therapy uses high-energy x-rays to kill tumor cells. Implant radiation therapy uses radioactive material placed directly into or near a tumor to kill tumor cells. Drugs used in chemotherapy, such as paclitaxel and carboplatin, 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 pelvic radiation therapy alone is more effective than vaginal implant radiation therapy, paclitaxel, and carboplatin in treating patients with endometrial cancer.
A Phase III Trial of Pelvic Radiation Therapy Versus Vaginal Cuff Brachytherapy Followed by Paclitaxel/Carboplatin Chemotherapy in Patients With High Risk, Early Stage Endometrial Carcinoma
- - To be considered eligible to participate in this trial, all patients must have undergone hysterectomy; bilateral salpingo-oophorectomy (open or laparoscopic approach) is strongly encouraged - Peritoneal cytology should be obtained on entering the peritoneal cavity, as described in the Gynecologic Oncology Group (GOG) Surgical Procedures Manual (https://gogmember.gog.org/manuals/pdf/surgman.pdf); pelvic and para-aortic lymphadenectomy are optional, but strongly encouraged (as staged patients enrolled on GOG-0210-molecular markers in endometrial carcinoma are eligible for this study) - The procedures may be performed via laparotomy or laparoscopy (including robot-assisted) as per the surgeon?s preference; the surgeon must record in the operative report whether a lymphadenectomy was performed (see link above to Surgical Procedures Manual) or not; a specific number of lymph nodes removed will not be utilized for eligibility, but the operative report should reflect that the procedure performed was consistent with the procedures described in the GOG Surgical Manual - If either a bilateral salpingo-oophorectomy or nodal dissection was not performed, post-operative pre-treatment computed tomography (CT)/magnetic resonance imaging (MRI) is required and must not demonstrate evidence suggestive of metastatic disease (adnexa, nodes, intraperitoneal disease); post-operative, pre-treatment CT/MRI must be performed if a pelvic and para-aortic nodal dissection was not performed - For the purposes of description, patients will be staged according to the International Federation of Gynecology and Obstetrics (FIGO) 2009 staging system; eligibility is defined based on clinical-pathologic features; patients with endometrial carcinoma (endometrioid types) confined to the corpus uteri or with endocervical glandular involvement fitting one of the following high-intermediate risk factor categories: - Age >= 70 years with one risk factor - Age >= 50 with 2 risk factors - Age >= 18 years with 3 risk factors - Risk factors: grade 2 or 3 tumor, (+) lymphovascular space invasion, outer ? myometrial invasion; patients with these risk criteria may be enrolled with either positive or negative cytology - Patients with stage II endometrial carcinoma (any histology) with cervical stromal invasion (occult or gross involvement), with or without high-intermediate risk factors - Patients with serous or clear cell histology (with or without other high-intermediate risk factors) are eligible provided the disease is uterine-confined (with or without cervical stromal invasion or endocervical glandular involvement), and with peritoneal cytology negative for malignancy - Patients must have GOG performance status 0, 1, or 2 - Absolute neutrophil count (ANC) >= 1,500/mcl (equivalent to Common Toxicity Criteria [CTCAE version [v] 3.0] grade 1) - Platelets >= 100,000/mcl (CTCAE v3.0 grade 0-1) - Serum creatinine =< institutional upper limit normal (ULN), CTCAE v 3.0 grade 0 - Note: If serum creatinine > ULN, a 24-hour creatinine clearance must be collected and must be > 50 mL/min - Bilirubin =< 1.5 x ULN (CTCAE v3.0 grade 1) - Serum glutamic oxaloacetic transaminase (SGOT) =< 2.5 x ULN (CTCAE grade 0-1) - Alkaline phosphatase =< 2.5 x ULN (CTCAE grade 0-1) - Neuropathy (sensory and motor) =< CTCAE v3.0 grade 1 - Patients who have met the pre-entry requirements; testing values/results must meet eligibility criteria - Patients must have signed an approved informed consent and authorization permitting release of personal health information
- - Patients who have already received non-surgical therapy for endometrial cancer including chemotherapy, radiation (example, pre-operative or post-operative brachytherapy), hormonal or biologic therapy - Patients identified with pathologically confirmed spread of cancer beyond the uterus and cervix to pelvic or para-aortic lymph nodes, adnexal structures, and/or other anatomic sites, or patients with serous or clear cell histology and with positive cytologic washings - Patients with nodal (for patients who did not have nodal dissection performed) or distant disease determined based on imaging studies; patients with suspicious nodes that have been biopsied (re-staging operation, fine needle aspiration [FNA]) and are pathologically negative will be eligible - Patients with a history of other invasive malignancies, with the exception of non-melanoma skin cancer, are excluded if there is any evidence of other malignancy being present within the last 5 years; patients are excluded if their previous cancer treatment contraindicates this protocol therapy; specifically, patients who have received prior radiotherapy directed to treat disease within the abdominal cavity or pelvis are excluded - Prior radiation of localized cancer of the breast, head and neck, thyroid, or skin is permitted, provided that it was completed more than 5 years prior to registration, and the patient remains free of recurrent or metastatic disease - Patients may have received prior adjuvant chemotherapy for localized breast cancer, provided that it was completed more than 5 years prior to registration, and the patient remains free of recurrent or metastatic disease - Patients who have contraindications to pelvic radiation therapy (RT) (e.g. pelvic kidney, connective tissue disease, inflammatory bowel disease, etc.) should be screened in advance and not be considered eligible for the trial - Patients with recurrent endometrial cancer - Patients with surgical or clinical, FIGO 2009 stage III or IV endometrial carcinoma - Patients with non-epithelial uterine malignancies such as uterine carcinosarcoma or leiomyosarcoma
