Mutation detection by highly sensitive methods indicates that p53 gene mutations in breast cancer can have important prognostic value.
Human cancer cells with a mutated p53 tumor-suppressor gene have a selective growth advantage and may exhibit resistance to ionizing radiation and certain chemotherapeutic agents. To examine the prognostic value of mutations in the p53 gene, a cohort of 90 Midwestern Caucasian breast cancer patients were analyzed with methodology that detects virtually 100% of all mutations. The presence of a p...
متن کاملPrognostic value of P53 gene mutations in a large series of node-negative breast cancer patients.
The most important subgroup of breast cancer patients for which reliable prognostic factors are needed are women without axillary lymph node involvement. Although overall, these patients have a good prognosis, it is known that 20-30% will experience a recurrence of the disease. To determine the prognostic significance of P53 tumor suppressor gene mutation, specimens from 113 primary breast canc...
متن کاملAdvances in Brief p53 Mutation in Plasma DNA and Its Prognostic Value in Breast Cancer Patients
Purpose: Tumor-specific DNA has recently been detected in the plasma of lung, head and neck, breast, and colon cancer patients. Detection of tumor-specific genetic materials in cancer patients at sites distant from the tumor, such as in the blood, may provide a unique and valuable tumor marker for diagnosis and prognosis. Experimental Design: The present investigation was aimed at determining t...
