Castle Biosciences (CSTL) is strengthening its commitment to esophageal cancer awareness through partnerships with key organizations during Esophageal Cancer Awareness Month in April 2025. The company is collaborating with the Esophageal Cancer Action Network (ECAN), the American Foregut Society (AFS), and The Gut Doctor Podcast.
With esophageal cancer's five-year survival rate at only 20%, early detection is crucial. The company's TissueCypher® test helps identify which Barrett's esophagus patients among the 1.5 million U.S. cases are at risk of progressing to cancer, affecting approximately 0.5% of cases.
Key initiatives include:
- ECAN partnership featuring digital media campaigns and awareness kits
- Special episode on AFS's All Fore Guts! podcast about screening importance
- Collaboration with The Gut Doctor Podcast discussing risk factors and treatment
Castle Biosciences (Nasdaq: CSTL) has secured the Top Workplaces USA Award for the fourth consecutive year, ranking 30th among 358 U.S. companies with 500-999 employees. The recognition, awarded by Energage and USA Today, is based on employee feedback through a third-party engagement survey.
Key highlights from the survey include:
- 95% participation rate (above 56% benchmark)
- 85% employee engagement score (exceeding 74% industry average)
- Assessment based on 15 culture drivers indicating high performance
The company, which specializes in innovative health tests for patient care, was selected from over 42,000 invited organizations. The achievement underscores Castle's commitment to maintaining a people-first culture and fostering an environment that promotes innovation and employee empowerment.
Castle Biosciences (CSTL) has published significant results from their DECIDE study regarding their DecisionDx-Melanoma test in melanoma patients. The study demonstrates the test's ability to accurately identify patients with less than 5% risk of sentinel lymph node (SLN) positivity who can safely avoid sentinel lymph node biopsy (SLNB) surgery.
Key findings show that DecisionDx-Melanoma influenced 85% of SLNB decisions. In patients with low-risk test results (Class 1A), none who underwent SLNB had positive nodes (0/35 patients). Notably, all patients with Class 1A results remained recurrence-free after two years of median follow-up, regardless of whether they underwent SLNB.
The study validates the test's alignment with National Comprehensive Cancer Network guidelines, which recommend avoiding SLNB when SLN positivity risk is below 5%. This helps reduce unnecessary surgical procedures, complications, and associated costs while focusing surgical interventions on higher-risk patients.
Castle Biosciences (CSTL) will present new data at the 11th World Congress of Melanoma and 21st EADO Congress in Athens, Greece (April 3-5, 2025), highlighting the clinical value of their DecisionDx-Melanoma test.
Two key studies will be presented: The first demonstrates the test's ability to stratify survival rates in stage IIB-IIC cutaneous melanoma patients, while the second shows its capability to identify early-stage patients at higher risk of central nervous system metastasis.
Key findings include:
- The test effectively stratified melanoma-specific and overall survival in stage IIB-IIC patients
- Patients with Class 2B (high risk) results showed significantly higher death risk
- DecisionDx-Melanoma was the only significant predictor of CNS metastasis in multivariable analyses
Dr. Brent Moody of Heritage Medical Associates emphasized that the test provides valuable biological insights complementing traditional staging, potentially improving melanoma outcomes through personalized care.
Castle Biosciences (CSTL) will present new validation data for its skin cancer tests at the NCCN 2025 Annual Conference. The company's DecisionDx-SCC test, earning a top-five abstract recognition, demonstrated enhanced risk stratification in a large cohort of 1,412 high-risk squamous cell carcinoma patients.
The study showed that combining DecisionDx-SCC with BWH staging significantly improved metastatic risk prediction within NCCN risk groups. Class 1 results indicated a nearly two-fold decrease in metastatic risk, while Class 2B showed more than a five-fold increase in risk for lower-stage NCCN High-Risk patients.
Additionally, new data for DecisionDx-Melanoma, tested in 6,892 patients with early-stage cutaneous melanoma, demonstrated the test's ability to predict mortality risk beyond traditional AJCC8 staging criteria. The study validated the test's effectiveness in identifying high-risk patients who might benefit from enhanced surveillance.
Castle Biosciences (CSTL) will present new data on its skin cancer diagnostic tests at the 2025 AAD Annual Meeting in Orlando. The company will showcase two significant studies:
1. A validation study of DecisionDx-SCC test involving 515 high-risk SCC patients, which demonstrated significant predictive ability for metastatic risk (p < 0.001).
2. An expanded analysis of DecisionDx-Melanoma test through collaboration with SEER Program Registries, encompassing nearly 10,000 patients. The study showed the test's ability to independently predict risk and its association with improved survival rates compared to untested patients.
Castle Biosciences (CSTL) reported strong financial results for 2024, with revenue reaching $332.1 million, a 51% increase from 2023. The company delivered 96,071 total test reports, up 36% year-over-year. Key highlights include:
