چکیده

Characterised by families with cutaneous malignant melanoma (CMM) and nervous system tumours. Initially described in a family with malignant melanoma and/or cerebral astrocytoma in eight members over three generations. Astroctytomas and cutaneous malignant melanoma have been identified in a number of well defined syndromes such as neurofibromatosis, Turcot’s, Lynch type II cancer, LiFraumeni and tuberous sclerosis. However, astrocytomas and CMM have been reported in families where the disease pattern does not fit the defined syndromes due to the absence of additional cancer types normally associated with these syndromes and mutations in genes known to predispose to these conditions (NF1, TP53, APC, MSH2 MLH1, TSC1, TSC2). In addition to astrocytoma, melanomaastrocytoma syndrome families show other tumours such as medullablastomas, glioblastoma multiforme, ependymoma, glioma, meningioma, neuroblastomas, schwannoma and acoustic neurilemmoma. All these tumours are of neural crest, mesenchymal and/or neuroepithelium origin. These families may/may not show evidence of the dysplastic naevus syndrome (DNS) common in familial melanoma.

The definition of hereditary prostate cancer (HPC) is based on the family history (pedigree). The suggested criteria include 1) nuclear family with three (or more) cases of prostate cancer, 2) prostate cancer in three successive generations, or 3) at least two men diagnosed with the disease before the age of 55 years. Familial aggregation of cases that don't fulfill the HPC criteria are defined...

Introduction: Radiation therapy is one of the main treatments for rectal cancer. In three-dimensional conformal radiotherapy, exposure of healthy tissue around the tumor is unavoidable. The small intestine is the most important organ at risk of rectal cancer radiotherapy. Intestinal complications are a major factor limiting the dose radiotherapy for rectal cancer. The most com...
