Shwachman–Diamond syndrome and solid tumors: 3 new patients from the French severe chronic neutropenia registry and literature review

Abstract

Shwachman-Diamond syndrome with Shwachman-Bodian-Diamond syndrome (SBDS) biallelic variants is a rare disorder that predisposes the carrier to malignant hemopathies but solid-cancer predisposition is poorly known. Among 155 cases entered in the French Severe Chronic Neutropenia Registry, three were identified original with malignant solid tumors (ovary, breast and esophagus). All cancers occurred in the fifth decade and, despite being at localized stages at diagnosis, they were rapidly fatal thereafter. No cancer was observed in the 14 HSCT survivors post transplantation. Based on our experience and the literature, age >40 years was the only apparent risk factor.
