  1. Glioblastoma in Turcot Syndrome. Astrocytic tumors in Turcot syndrome type 1 are clinically indistinguishable from sporadic tumors. These neoplasms are typically high grade, mostly glioblastoma, with significant mass effect as seen in this FLAIR image. Medulloblastoma in Turcot Syndrome
  2. The following are two most frequently obtainable brain tumors in Turcot syndrome are: Glioblastoma. This is a very aggressive form of astrocytoma(one type of brain tumor , where the astrocytes present in the synapse and glial cells are having abnormal cell proliferation). The clinical finding of the glioblastoma is common with Turcot syndrome.
  3. ant disorder caused by germline mutation in one of the DNA mismatch repair (MMR) genes. LS is among the most prevalent cancer syndromes in man and is estimated to account for 1-6% of all colorectal cancers (Lynch & de la Chapelle, 2003)
  4. Glioblastomas, astrocytomas and oligodendrogliomas linked to Lynch syndrome. In Lynch syndrome brain tumors occurred in 14% of the families with significantly higher risks for individuals with MSH2 gene mutations and development of childhood brain tumors in individuals with constitutional MMR defects. In Lynch syndrome brain tumors occurred in 14%.
  5. In cases of Turcot syndrome, the brain tumor is often a glioma. Additional brain tumors that have been associated with Turcot syndrome include medulloblastomas, glioblastomas, ependymomas, and astrocytomas. Medulloblastomas occur with greater frequency in the type 2 form of Turcot syndrome
  6. Turcot syndrome (TS) is a rare hereditary disorder clinically characterized by the occurrence of primary tumors of the colon and the central nervous system (CNS). Here we present the case of an 11-year-old boy with a synchronous clinical presentation of both glioblastoma multiforme (GBM) and colonic adenocarcinoma

  5. A rare case of Turcot's syndrome is reported in a long-time survivor of glioblastoma multiforme. The patient was treated for his tumor in 1976 with macroscopically complete surgical resection and radiotherapy consisting of 60 Gy to the tumor bed and 40 Gy to the whole brain

The precise underlying cause of glioblastoma is not yet well understood. A potential genetic link. While most glioblastomas are not believed to be inherited, the risk of developing this type of brain cancer appears to be elevated in individuals who are diagnosed with certain genetic cancer syndromes, such as: Neurofibromatosis type 1; Turcot. Turcot syndrome (TS) was originally described by Turcot in 1959 [1-3]. It is characterized by the development of primary tumors of the central nervous system (CNS), such as glioblastoma multiforme (GBM) and medulloblastoma, along with numerous adenomatous colorectal polyps and colonic adenocarcinoma In the present case, a 60-year-old patient with glioblastoma multiforme and a history of hereditary malignomas is described as an example of a HNPCC-associated Turcot's syndrome. New molecular biological methods and results give deeper insight into clinical syndromes, and the better understanding improves diagnostics, therapy, and outcome. Most glioblastomas are not inherited. They usually occur sporadically in people with no family history of tumors. However, they can rarely occur in people with certain genetic syndromes such as neurofibromatosis type 1, Turcot syndrome and Li Fraumeni syndrome. All of these conditions are inherited in an autosomal dominant manner
