Conventional peritoneal cytology lacks the prognostic significance of detecting local or peritoneal recurrence in colorectal cancer: An Egyptian experience.

Background And Aim: Colorectal cancer (CRC) accounts for over 8% of all deaths each year, with 1.2 million new cases diagnosed annually worldwide. It represents the seventh most common cancer in Egypt.

Osteosarcoma of the jaw: Challenges in the diagnosis and treatment.

Purpose: Osteosarcomas rarely affect jaw bones. Patients are usually older than those who suffer long bone sarcomas, with a rare incidence of metastasis. This is suggestive of a different pattern of behavior compared with long bone sarcomas.

Association of Osteopontin Gene Polymorphisms with Colorectal Cancer.

We investigated the association of the Osteopontin (OPN) (rs9138 and rs1126616) polymorphisms with colorectal cancer (CRC). One hundred CRC patients and 112 healthy individuals were subjected to OPN (rs9138 and rs1126616) genotyping and measurement of OPN protein plasma level. The C allele of OPN rs1126616 and the CC haplotype were significantly higher in CRC patient (p = 0.

Management Head and Neck Ewing's Sarcoma Family of Tumors: Experience of the National Cancer Institute, Cairo University.

Background: Ewing's sarcoma accounts for 4-6% of primary malignant bone tumors and it affects the head and neck in only 1-4% of cases. The purpose of this study was to review the NCI experience with Ewing's sarcoma of the head and neck in children.

Patients And Methods: A retrospective analysis of patient files with head and neck Ewing's sarcoma treated at the National Cancer Institute, Cairo University, Egypt, during the period from 1997 to 2008 was done.

The role of surgical management in pediatric germ cell tumors (GCTs), NCI case series.

Purpose: To review the experience of a tertiary referral center in pediatric germ cell tumors (GCTs) in the last 8 years and to investigate the impact of surgery and site of disease on prognosis.

Patients And Methods: We retrospectively analyzed the cases of pediatric germ cell tumors at National Cancer Institute over an 8 years period. Data concerning diagnosis, surgery and medical decisions were reviewed and analyzed for all patients.

Medullary thyroid cancer.

Medullary thyroid cancer is a rare neoplasm that arises from the parafollicular C cells. It occurs in a sporadic form, or less commonly as a hereditary form, as part of multiple endocrine neoplasia syndromes types 2A and 2B. The RET proto-oncogene is currently the primary factor that is implicated in the hereditary forms of this neoplasm.
