Core Viewpoint - Meizhong Jiahe (2453.HK) has achieved a significant breakthrough in the treatment of choroidal malignant melanoma by successfully completing the first proton therapy in China, which preserves the patient's eye and vision, filling a treatment gap in the country [1][2]. Group 1: Treatment Innovation - The proton therapy using "pencil beam scanning" technology allows for high-dose radiation to be precisely focused on the tumor while minimizing damage to surrounding critical structures, marking a shift from destructive to functional treatment [1][2]. - Traditional treatment methods primarily involved enucleation, which resulted in permanent blindness and facial disfigurement for patients [1]. Group 2: Patient Outcomes - The first patient treated, a 45-year-old male from Hunan, experienced a significant improvement in vision from 0.1 to 0.4 within 48 hours post-treatment, with tumor markers decreasing by 90% and no complications such as corneal ulcers or retinal detachment [2]. - The patient expressed satisfaction with the treatment, stating he was able to retain his eye and continue working, contrasting with his initial expectation of undergoing enucleation [2]. Group 3: Market Potential - Proton therapy is recommended as a first-line treatment for choroidal melanoma in the 2024 NCCN guidelines, providing evidence-based support for eye-preserving strategies [2]. - With approximately 2,500 new cases of choroidal malignant melanoma diagnosed annually in China, Meizhong Jiahe's advancements in this field are expected to benefit domestic patients and create substantial market opportunities for the company [2].
