研究概览
简要总结
The goal of this clinical research study is to find the sentinel lymph node (SLN) (s) and biopsy it (them) to see if the patient has small or low volume metastatic disease that would otherwise have been missed.
详细描述
You have had your conjunctival or eyelid tumor surgically removed or it is scheduled to have it removed. You will have lymphatic mapping before the tumor is removed. Lymphatic mapping is when a small volume of Tc99m-Sulfur colloid is injected by an ophthalmologist after which some radiologic images are taken.
If you are able to become pregnant, blood (about 2 teaspoons) will be drawn for a pregnancy test, within 7 days before the biopsy. To take part in this study, you must not be pregnant.
You will then go to the operating room and have intraoperative SLN mapping and biopsy. If the SLN is positive on permanent section, you will go on to have complete lymph node dissection, which involves removal of all the lymph nodes around the positive SLN. Then the disease will be restaged and you may require further treatment after consultation with their oncologist.
Your medical record will be reviewed, and information from your medical record will be recorded and reviewed to help researchers better identify those patients who have microscopic lymph node disease. The information collected from your medical records will include information about your sex, age, what type of cancer that you have, as well as the size of the cancer and its location.
Researchers hope to identify those patients who have microscopic lymph node disease before it becomes clinically obvious. With this technique, researchers could potentially identify occult metastatic disease which would otherwise go unnoticed until it was too advanced. Patients in this study will have to see the ophthalmologist every three months and have the usual metastatic workup, which is routine for conjunctival/eyelid melanoma.

主要结局
Number of Patients with Sentinel Lymph Node (SLN) Positivity in Conjunctival/eyelid Melanomas
时间窗: 3 months
The frequency of lymphatic drainage basins for bulbar versus palpebral conjunctiva and for nasal and the temporal quadrants estimated with 95% confidence intervals. The rate of identification of SLN evaluated with a confidence interval. The probability of positive SLN in primary conjunctival and eyelid melanoma estimated.
