We report a case of a 28-year-old female patient diagnosed as synchronous esophageal and tongue cancer, and underwent two cycles of radiation therapy, inevitably in the condition of coronavirus disease 2019 infection. She received radiation therapy of 30 Gy to esophageal mass with neoadjuvant aim in her first-round radiation therapy, and later received 27 Gy to tongue cancer surgical bed with adjuvant aim in her second-round radiation therapy. With no further treatment, she has been maintaining no evidence of disease state for 7 months. Managing Fanconi anemia patients with multiple cancers using radiation therapy is feasible, in which cases a dose de-escalation may be important considering the radiation toxicity and possible future re-treatment.  \nKeywords: Radiotherapy, Head and neck neoplasms, Esophageal neoplasms, Radiation injuries, COVID-19  \nIntroduction  \nFanconi anemia (FA) is a rare congenital syndrome that presents with aplastic anemia and bone marrow hypoplasia in young age and develops myelodysplastic syndrome (MDS) and acute myeloid leukemia during the life course [1]. FA is caused by a defect in a tumor-suppressive pathway, which protects the human genome and maintains genomic stability by repairing DNA interstrand crosslinks [2]. The resulting consequence is skin anomalies including hyperpigmentation and café-au-lait spots (approximately 40%), skeletal anomalies of the head including microcephaly and hydrocephaly (approximately 20%), increased risk of MDS (approximately 6,000-fold greater risk) and leukemia (approximately 700-fold greater risk), increased risk of solid tumor (more than 10% per year by age 45) [3,4]  \nAnother clinical significance of FA patients regarding radiation treatment stems from their inherent sensitivity to DNA damage and the resulting toxicity of varying degrees. Some suggest that the risk of mortality after radiotherapy in FA, pertaining to either acute or chronic radiation toxicity, may amount to as high as 50%  \n[5]. Even those who survive radiotherapy may experience severe local symptoms such as mucositis, dysphagia, stenosis, wound problems, as well as systemic symptoms, the most notable being bone marrow failure. Thus, completion of radiotherapy in an uninterrupted schedule may be limited in many cases, and guidelines recommend radiotherapy to be used only in circumstances of absolute necessity [5,6].  \nHere, we present a case of a 28-year-old female patient who was diagnosed with synchronous esophageal and tongue cancer and u","cbCaikeUpXel8jYl","https://ap.wps.com/l/cbCaikeUpXel8jYl","pdf",747945,"English","# Introduction\n## Fanconi anemia and radiation sensitivity\n## Rationale for radiotherapy under guidelines\n# Case Report\n## Presenting symptoms and diagnosis\n## COVID-19 impact on treatment planning\n## Radiotherapy planning and delivery","[{\"question\":\"Why is radiotherapy challenging for patients with Fanconi anemia?\",\"answer\":\"Fanconi anemia causes heightened sensitivity to DNA damage, leading to serious acute and chronic radiation toxicity.
