Fludeoxyglucose (FDG) F 18 PET Scan, CT Scan, and Ferumoxtran-10 MRI Scan Before Chemotherapy and Radiation Therapy in Finding Lymph Node Metastasis in Patients With Locally Advanced Cervical Cancer or High-Risk Endometrial Cancer

PRIMARY OBJECTIVES:

I. Determine the diagnostic sensitivity and specificity of preoperative fludeoxyglucose F 18 positron emission tomography (FDG-PET)/CT scanning and ferumoxtran-10 MRI scanning in identifying metastases to abdominal (common iliac, para-aortic, and paracaval) lymph nodes in patients with locoregionally advanced cervical carcinoma.

II. Determine the diagnostic sensitivity and specificity of preoperative FDG-PET/CT scanning and ferumoxtran-10 MRI scanning in identifying metastases to retroperitoneal abdominal lymph nodes in patients with high-risk endometrial cancer.

SECONDARY OBJECTIVES:

I. Determine the diagnostic sensitivity and specificity of preoperative FDG-PET/CT scanning and ferumoxtran-10 MRI scanning in identifying metastases to pelvic lymph nodes and pelvic and abdominal lymph nodes combined in patients with locoregionally advanced cervical carcinoma or high-risk endometrial cancer.

II. Compare the additive diagnostic value of CT fusion (PET/CT scan) vs PET scanning alone in identifying metastases to pelvic, abdominal, and combined (all regions) lymph nodes in these patients.

III. Compare the diagnostic sensitivity and specificity of PET/CT scanning vs ferumoxtran-10 MRI scanning in identifying metastases to pelvic, abdominal, and combined lymph nodes in these patients.

IV. Compare the diagnostic sensitivity and specificity of ferumoxtran-10 MRI vs MRI alone, in terms of size criteria in the abdomen and pelvis, in these patients.

V. Determine the percentage of patients with locoregionally advanced cervical cancer or high-risk endometrial cancer who have biopsy-proven disease outside the abdominal or pelvic lymph nodes detected by PET/CT scanning.

VI. Determine the accuracy of MRI in determining the depth of myometrial invasion and involvement of cervix in patients with high-risk endometrial cancer.

VII. Determine the complications associated with extraperitoneal or laparoscopic abdominal and pelvic lymphadenectomy in patients with locoregionally advanced cervical cancer.

VIII. Determine the cause(s) of delay in the initiation of radiotherapy or interruption in radiotherapy in patients with locoregionally advanced cervical cancer.

IX. Collect data on the adverse effects of ferumoxtran-10 in patients with locoregionally advanced cervical carcinoma or high-risk endometrial cancer.

X. Compare the size of lymph nodes in pre- and post-ferumoxtran-10 MRI's in a subset of forty patients.

OUTLINE: This is a multicenter study.

Patients receive fludeoxyglucose F 18 (FDG) IV followed 60 minutes later by positron emission tomography (PET)/CT scanning on day 1. Patients also receive ferumoxtran-10 IV over 30-45 minutes on day 1 (or 24-36 hours before MRI) and undergo MRI on day 2. Patients undergo extraperitoneal, laparoscopic, or trans-peritoneal lymphadenectomy with pelvic and abdominal lymph node biopsy within 2 weeks after PET/CT scan. Patients diagnosed with metastatic disease prior to lymph node biopsy proceed directly to primary treatment. Patients with cervical cancer undergo chemoradiotherapy within 4 weeks of PET/CT scan.

After completion of study therapy, patients are followed at 6 weeks, 6 months, every 3 months for 2 years, and then every 6 months for 3 years.

• Any cell type allowed
• High-risk endometrial carcinoma meeting 1 of the following criteria:

• Grade 3 endometrioid or non-endometrioid endometrial carcinoma (clear cell or serous papillary) or carcinosarcoma diagnosed from an endometrial biopsy or dilation and curettage or
• Grade 1 or 2 endometrioid endometrial carcinoma with cervical stromal involvement overt on clinical examination or confirmed by endocervical curettage
• Under consideration for chemoradiotherapy (patients with cervical cancer)
• Undergone appropriate surgery for cervical or endometrial carcinoma with appropriate tissue available for histologic evaluation to confirm diagnosis and stage
• Appropriate surgical candidate to undergo extraperitoneal or laparoscopic lymph node sampling OR hysterectomy and lymph node sampling
