Conjunctival melanoma is a rare, life- and sight-threatening ocular malignancy sharing molecular features with cutaneous and mucosal melanoma. Despite current clinical approaches, high recurrence rates and frequent metastases pose significant challenges in management. Immune checkpoint inhibitors such as ipilimumab and nivolumab have revolutionized cutaneous melanoma treatment, but their efficacy in conjunctival melanoma remains largely unexplored.

Background: Guidelines recommend universal mismatch repair (MMR) tumour testing of colorectal adenocarcinomas (CRCs) to screen for Lynch syndrome (LS). However, its implementation remains disjointed and referral for genetic testing dismal, particularly among minorities. We aimed to increase referral, cancer genetic testing and eventually LS diagnosis by developing the CLEAR LS (Closed Loop Enhanced Assessment and Referral for Lynch Syndrome) intervention, a systems approach which in the second phase was automated.

Prostate cancer is a leading cause of morbidity and mortality for adult males in the US. The diagnosis of prostate carcinoma is usually made on prostate core needle biopsies obtained through a transrectal approach. These biopsies may account for a significant portion of the pathologists' workload, yet variability in the experience and expertise, as well as fatigue of the pathologist may adversely affect the reliability of cancer detection.
