Popis: Few reports have examined whether prophylactic allogeneic hematopoietic cell transplantation (HCT) for X-linked lymphoproliferative syndrome type 1 (XLP1) improves the prognosis. We compared the prognosis of symptomatic probands and affected siblings in the same family. Twenty-two cases (10 probands and 12 affected siblings) in Japan, the United Kingdom, and the United States were analyzed. The overall survival (OS) rate at 5 years after diagnosis was 70.0% in probands and 91.7% in affected siblings (p = 0.0789). The prognosis of patients who developed symptoms of XLP1 before HCT and those who did not was also compared. The 5-year probability of OS from the time of diagnosis in asymptomatic patients (100%) was significantly better than that in symptomatic patients (66.7%). These results suggested that early HCT as soon as the diagnosis is made improves the prognosis in asymptomatic XLP1 patients.
