چکیده
Cancer of the breast is one of the most common human neoplasm, many environmental, personal and genetic factors have been implicated as a risk factors to develop breast cancer. Tumor size, histological subtype, grading, lympho-vascular permeation, and lymph node involvement are the cardinal independent factors influence prognosis and response to different therapeutic modalities. Among other prognostic factors, ER/PR status, Her2 oncogen, DCIS/invasive component ratio, and local tumor spread are highly impact prognosis and systemic anticancer therapy. Recently some molecular markers came out to the scene, as p53 mutations and Bcl-2 amplification, which can be detected by gene-expression profiling, are associated with higher probability of tumor recurrence and low overall survival. In fact, different molecular and histological subgroups show variable prognosis and different response to chemotherapy and other treatment regimes. Finally, we are looking for further studies to improve current prognostic markers that will reflect on better treatment tools.

متن کاملAxillary irradiation in breast cancer; does meticulous contouring make a difference?
Background: Due to the current trends towards replacing axillary dissection with radiotherapy, the need for more precise definition for different nodal stations becomes a must to ensure safe and adequate dose coverage. So, our study aimed to evaluate the coverage of axillary nodal volumes based on Project on Cancer of the Breast (PROCAB) guidelines, for cases previously treated with our standar...
متن کاملUltrasound-guided boost irradiation of tumor cavity after lumpectomy in breast cancer
Background: After breast conserving surgery, most recurrences occur around the primary tumor site. This justifies the use of boost radiotherapy to the primary site of tumor. Surgical scar is not always a good surrogate for the location of the lumpectomy cavity. The aim of this study was to evaluate ultrasonic guidance for detection of the lumpectomy cavity after breast conserving surgery ...
