1. Identify the rate of SLN (sentinel lymph node) positivity for eyelid sebaceous gland carcinomas.
2. Identify the false negative events associated with SLN biopsy for sebaceous gland carcinomas.
Record any side effects associated with SLN biopsy for sebaceous gland carcinoma of the eyelid.
If you agree to take part in this study, you will come into the clinic at 2 different times for lymphatic mapping and SLN mapping/biopsy.
Lymphatic mapping is a procedure in which a small amount of a radioactive substance called Tc99m-Sulfur colloid is injected into the eyelid around the tumor(s) to make the lymph nodes visible on an imaging scan. After Tc99m-Sulfur colloid is injected, you will have a single photon emission computed tomography/computed tomography (SPECT/CT) scan performed.
For the SLN biopsy procedure, you will go to the operating room and undergo SLN mapping and biopsy under general anesthesia. A small amount of Tc99m-Sulfur colloid will again be injected into the eyelid around the tumor(s), to help the doctor find any possible SLNs. If you have your tumor removed earlier, the small amount of Tc99m-Sulfur colloid will be injected into the eyelid around the area of earlier tumor site. Then you will have the SLN biopsy. To collect the SLN biopsy, the doctor will make a small incision into the tissue over the lymph nodes that have picked up the Tc99m-Sulfur colloid. The lymph nodes will then be removed and tested for signs of metastatic disease.
If the biopsy shows signs of metastatic disease, you will receive the standard of care for metastatic cancer of the eyelid. You will be separately consented for this.
Length of Study:
You will continue to be observed on study for 5 years after the biopsy. You will come to the clinic for follow-up scans and tests during this time.
Every 3 months for the first year after the biopsy, and every 6 months after that until 5 years after the biopsy, you will have an eye exam to check the status of the disease.
You will have a chest x-ray, as well as a head and neck CT or MRI, every 6 months for the first year after the biopsy to make sure the disease has not come back. The head and neck CT or MRI will be repeated 1 time each year for 5 years after the biopsy, as well as whenever the doctor thinks it is needed.
You will have an ultrasound of lymph nodes in the cheek and neck area 1 year after the primary tumor was removed to check for metastatic disease.
This is an investigational study. The described procedure for lymphatic mapping and biopsy is standard of care for other regions of the body. Lymphatic mapping and SLN biopsy for eyelid cancers are investigational.
Up to 20 participants will take part in this study. All will be enrolled at M. D. Anderson.

We recently developed a new subcortical mapping technique based on the concept of stimulating the tissue at the site of and synchronously with resection. Our hypothesis was that instead of performi...
We present Eagle, a new method for multi-locus association mapping. The motivation for developing Eagle was to make multi-locus association mapping "easy" and the method-of-choice. Eagle's strengths a...
Methods used for studying the interactions of antibodies with specific regions of protein antigens. Important applications of epitope mapping are found within the area of immunochemistry.
Mapping of the linear order of genes on a chromosome with units indicating their distances by using methods other than genetic recombination. These methods include nucleotide sequencing, overlapping deletions in polytene chromosomes, and electron micrography of heteroduplex DNA. (From King & Stansfield, A Dictionary of Genetics, 5th ed)
Short tracts of DNA sequence that are used as landmarks in GENOME mapping. In most instances, 200 to 500 base pairs of sequence define a Sequence Tagged Site (STS) that is operationally unique in the human genome (i.e., can be specifically detected by the polymerase chain reaction in the presence of all other genomic sequences). The overwhelming advantage of STSs over mapping landmarks defined in other ways is that the means of testing for the presence of a particular STS can be completely described as information in a database.
