简要总结
The goal of this clinical research study is to learn how often using a positron emission tomography-computed tomography (PET-CT) scan in addition to a standard computed tomography (CT) scan will change the surgical plan in patients with metastatic melanoma.
详细描述
If you agree to take part in this study, you will have a PET-CT scan performed. The picture produced by this scan will be compared to a standard CT scan to see if any additional tumors can be located. If the study doctor thinks that additional tumors are present, a biopsy may need to be performed to check the status of the tumors. The type of biopsy will depend on where the tumor(s) are located on the body. If a biopsy is performed, you will sign a separate consent.
Screening Tests:
Women who decide to take part in this study will be asked if they think they might be pregnant at the start of the study. Women who are unsure if they may be pregnant or think that they may be pregnant must have a negative blood (about 1 teaspoon) pregnancy test.
PET-CT Scan Procedure:
Before the PET-CT scan is performed, you will be asked to avoid stressful exercise for 24 hours. Starting about 12 hours before the scan, you should eat a high protein diet and limit the amount of carbohydrates you eat. Starting about 6 hours before the scan, you should not eat or drink anything other than water (fast) until after the scan is done. You may continue to take prescribed drugs with water during the fasting period.

入选标准
- •AJCC Stage III melanoma with clinically evident (macroscopic) disease, either by physical examination or on conventional imaging, or AJCC stage IV melanoma with metastatic site(s) considered surgically resectable. The initial decision regarding surgical candidacy should be made by surgical oncologist. Patients with indeterminate CT findings that are larger than 1 cm outside of the field of the potential surgery will be also included.
- •Contrast- enhanced CT of chest, abdomen and pelvis performed either at MDACC or outside of the institution should indicate surgical candidacy. Outside CT imaging studies should be of acceptable quality, as determined by the evaluating radiologist. PET-CT per protocol must be performed within 30 days from the contrast-enhanced CT.
- •All minor patients will be excluded to avoid excessive radiation dose. There is data suggesting small but statistically significant increased risk for secondary malignancy due to the cumulative dose of radiation exposure associated with diagnostic imaging. Children are most sensitive to radiation long term adverse effects. Therefore current pilot study will accrue adults only. If the result of this study will indicate potential advantage of PET-CT, this data can be weighted against radiation exposure risks to decide upon imaging strategies in pediatric patients with melanoma.
排除标准
- •Regional disease limited to an involved sentinel lymph node (occult or microscopic regional nodal metastasis).
- •Availability of prior PET-CT, performed within 60 days of initial clinical appointment.
