Merkel cell carcinoma (MCC) is a rare skin cancer that mainly affects the elderly, and whose incidence is increasing. Although the exact origin of this cancer remains uncertain, research in recent years has revealed that MCC develops through two oncogenesis pathways: virally induced by the Merkel polyomavirus (80% of cases) and induced by mutations linked to ultraviolet rays (20% of cases). MCC is an aggressive cancer, with a high mortality rate and limited therapeutic options in advanced stage.

Purpose: We developed software that can analyze central lung distance (CLD) and central skin distance (CSD) in deep inspiration breath hold (DIBH) irradiation and verified the reproducibility of the DIBH irradiation method in our hospital.
Methods: CLD and CSD were analyzed using In-house software using cine images acquired during treatment; intra- or inter-fractional motion was calculated from the obtained data and compared with other reports using systematic error (ΔΣ) and random error (Δσ).
Results: The ΔΣ and Δσ were 1.

Background: Merkel cell carcinoma (MCC) is an aggressive skin cancer with poor survival rates. Immune checkpoint inhibitors (ICIs) were FDA-approved for advanced MCC in 2017, but their real-world survival impact remains unclear.
Objective: Evaluate whether ICI introduction in the US corresponded with improved survival.

In-transit metastases (ITM) are estimated to occur in 5-10% of primary cutaneous melanomas. They are classified as stage III disease in the American Joint Committee on Cancer classification system and are associated with approximately a 30% 10-year survival rate. The management of ITM is not standardized.
