DecisionDx-Melanoma identifies patients with negative sentinel lymph node biopsies who are at high risk of metastasis
Data also presented on new multi-analyte test that predicts treatment response in esophageal cancer with initial data in rectal cancer
FRIENDSWOOD, Texas, May 14, 2014 /PRNewswire/ -- Castle Biosciences Inc. announced today that abstracts reporting additional clinical validation data for two of its molecular tests -- one focused on melanoma and the other on esophageal adenocarcinoma -- will be presented at the 50th Annual Meeting of the American Society of Clinical Oncology (ASCO) in Chicago, May 30-June 3, 2014. Data presented at ASCO will show significant advances for these tests that address important unmet clinical needs.
In cutaneous melanoma, sentinel lymph node (SLN) positivity has been the standard for identifying patients who are at high risk for metastasis, yet two of three melanoma patients who metastasize will be sentinel lymph node negative.
"The initial clinical goal for our melanoma gene expression profile test was to identify these two out of three patients who are at high risk for metastasis, regardless of SLN biopsy eligibility," commented Derek Maetzold, President and CEO of Castle Biosciences. "At ASCO we will present data that focus on a cohort of patients who received both our gene expression profile test and a SLN biopsy, and confirm our initial validation study results."
Cutaneous Melanoma Test
Poster Highlights Presentation: "Gene expression profile test (GEP) prediction of metastasis-free (MFS) and overall survival (OS) in a cohort of cutaneous melanoma (CM) patients undergoing sentinel lymph node biopsy (SLNB)" (Abstract # 9022)
Esophageal Cancer Test
Poster Presentation: "A proprietary multi-analyte test to predict neoadjuvant treatment response for esophageal and rectal adenocarcinoma patients" (Abstract # 4085)
The majority of ASCO Annual Meeting abstracts are now available on ASCO's website at www.asco.org.
Also at the ASCO meeting, attendees will be able to visit the Castle Biosciences exhibit (Booth # 20137) to learn more about the DecisionDx-Melanoma gene expression profile test and the DecisionDx-EC multi-analyte test for esophageal cancer, as well as the DecisionDx-Thymoma test and the newly available DecisionDx-Mesothelioma test.
Cutaneous melanoma is diagnosed in approximately 76,000 people in the U.S. each year, according to the American Cancer Society. Seventy-five percent are diagnosed as Stage I or II, meaning there is no evidence of the melanoma spreading beyond the primary tumor. Melanoma is not the most prevalent form of skin cancer, but it is the most aggressive. Unlike other more common skin malignancies like basal cell and squamous cell carcinomas, melanoma often spreads to other parts of the body, either via the lymphatic or blood system, resulting in cancers of distant organs including the brain or lungs. While it represents just 4% of skin cancers, melanoma accounts for about 80% of skin cancer-related deaths. More information is available at www.skinmelanoma.com
About Esophageal Cancer
The esophagus carries food and liquid from the mouth to the stomach. There are two main types of esophageal cancer: adenocarcinoma and squamous cell carcinoma. The most common form of the disease in the U.S. is adenocarcinoma and is most prevalent in Caucasian men between the ages of 50 and 70. Adenocarcinoma, which is one of the fastest growing cancers in the country, has also been linked to obesity – perhaps related to chronic exposure to stomach acid. According to the National Cancer Institute, about 18,000 Americans were diagnosed with esophageal cancer in 2013. More information can be found at www.myesophagealcancer.com
