P53 gene is a tumor suppressor gene that stops the formation of tumors. If a person inherits only one functional copy of the p53 gene from his parents, he will be predisposed to cancer and usually develop several tumors in various tissues in early adulthood. However, mutations in p53 are found in most tumor types, and so contribute to a number of molecular events leading to tumor formation. There are numerous informations that exist on all aspects of p53 normal function and mutant expression in human cancers, reflecting its key role in the pathogenesis of human cancers.

A subset of cancer survivors experience cognitive deficits that can last for many years after the completion of chemotherapy. The etiology of this problem is largely unknown, so the present study aimed to assess cognitive functioning in childhood patients with cancer and to investigate the proposed disposing factors including variables related to disease, treatment, and some socio-demographic characteristics. In a case control study parents of 67 cancer patients aged 8-12 years, completed the parent proxy report of PedsQL™ 3.0 Cognitive Functioning Scale (Arabic versions), as well as a separate sheet for socio-demographic data. Control group consisted of 37 healthy subjects from the same age group were subjected to the same methodology for comparison. All patients under the study have successfully accomplished their treatment protocol and were in complete remission during the evaluation. Hematological malignancies represented 70.1% of the patients sample, with the highest proportion for ALL (52.2%). Brain tumors represented 40% of the solid malignancies (29.9% of the study patients). Cognitive functioning score was significantly lower in the solid group (69.6±37.3) compared to the hematologic group (85.1±22.2) (t = 2.1, p =0.038). Cognitive functioning score was also lower in solid group versus control subjects (p =0.047), while it showed no significant difference between hematological malignancies and control group. Older age at diagnosis, urban residence, illiterate mothers, higher duration of treatment as well as long duration of hospital admission were associated with a lower cognitive score in the solid tumors group compared to hematological group.
