[Meta analysis of the use of Bayesian networks in breast cancer diagnosis].

The aim of this study was to determine the accuracy of Bayesian networks in supporting breast cancer diagnoses. Systematic review and meta-analysis were carried out, including articles and papers published between January 1990 and March 2013. We included prospective and retrospective cross-sectional studies of the accuracy of diagnoses of breast lesions (target conditions) made using Bayesian networks (index test).

Accuracy of telomerase in estimating breast cancer risk: a systematic review and meta-analysis.

Objective: To determine the accuracy of telomerase activity in predicting a higher risk for breast cancer.

Study Design: A quantitative systematic review was performed. Studies that detected telomerase activities in breast tissue were included.

Ipsilateral breast tumor reappearance in patients treated with conservative surgery after primary chemotherapy. The role of surgical margins on outcome.

Background And Objectives: To evaluate the ipsilateral breast tumor reappearance (IBTR) rate after breast conservative surgery (BCS) following primary chemotherapy (PC) and to assess whether positive margins affects IBTR rate and overall survival (OS).

Methods: Three hundred nine women candidates for mastectomy received PC before surgery. One hundred ninety-five patients (63.

The sentinel lymph node biopsy under local anesthesia in breast carcinoma: experience of the European Institute of Oncology and impact on quality of life.

Background: Sentinel lymph node biopsy performed under local anesthesia currently represents one of the main fields of investigation in breast cancer surgery because of its positive impact on the management and organisation of treatment. We previously published our preliminary experience with 115 patients; here we present an update of our experience with particular attention devoted to quality of life.

Patients And Methods: From September 2000 to April 2003 we treated 244 patients with this technique.
