Serial Cancer Development Three Times in a Patient with Fanconi Anemia

Fanconi anemia (FA) is characterized clinically by bone marrow failure, congenital malformations, sensitivity to DNA cross-linking agents, and increased risk of malignancy. Hematological cancer is the best-described malignancy in patients with FA, but the susceptibility to the development of solid tumors is also well documented, especially after hematopoietic stem cell transplantation (HSCT). With regard to the development of solid tumors in patients with FA, head and neck, esophageal, and anal squamous cell carcinoma are well known, but reports of lung cancer are extremely rare. Here, we describe an FA patient with a history of HSCT that developed 3 serial cancers − oral, esophageal, and nonsmall cell lung cancer − over a period of 6 years. The third lesion was nonsmall cell lung cancer and its location corresponded closely to the field of irradiation treatment for prior esophageal cancer. The occurrence of lung cancer in patients with FA is uncommon, but FA patients should be screened regularly and serially. Our case also indicated the importance of the irradiated field as a location for subsequent cancer development.
