Traitement non chirurgical des rectites radiques chroniques hémorragiques

Fanconi anemia and vaginal squamous cell carcinoma

Fanconi Anemia (FA) is an autosomal recessive disease characterized by chromosome instability, cellular hypersensitivity to DNA cross-linking agents, and increased predisposition to malignancies. We describe here a 28 year-old female with FA and vaginal squamous cell carcinoma treated by radiation therapy alone. The patient developed arm phlebitis, pulmonary fungal infection, and severe rectal bleeding, followed by hypocalcaemia, hypokalemia, vaginal bacterial and fungal infection, with subsequent leg and arm phlebitis, perineal abscess, and sepsis. The patient died 12 weeks later.

[Normal tissue tolerance to external beam radiation therapy: anal canal]

The anal canal is regarded as an organ at risk more often in pelvis radiation, but also in brachytherapy. Acute or chronic complications depend on its different components and are different from the anal margin or the rectum. The toxicity scale can be the NCI CT C version 3, completed by the tardive toxicity SOMALENT scale. The mean dose and maximal dose are recognized as predictors of complications. The maximum recommended dose despite the paucity of literature is 55 Gy.
