Surgical management of breast cancer in BRCA-mutation carriers: a systematic review and meta-analysis.

This meta-analysis investigates the oncological safety of breast-conserving therapy BCT in BRCA-mutation carriers and the risk for contralateral breast cancer (CBC) compared with non-carriers, potential risk factors for ipsilateral breast recurrence (IBR) or CBC and grades these factors based on the level of evidence. A PubMed search was conducted through April 2013 to identify studies that described the risk for IBR and CBC after BCT in BRCA-mutation carriers versus non-carriers as well as studies that investigated risk factors for IBR and CBC in BRCA-mutation carriers. Results were summarized using meta-analysis when sufficient studies were available.

Comparative survival with diverse chemotherapy regimens for cancer of unknown primary site: multiple-treatments meta-analysis.

Objectives: To synthesize the evidence from randomized controlled trials concerning systemic treatment regimens for patients with cancer of unknown primary site (CUP).

Data Sources: PubMed and the Cochrane Library Central Registry of Controlled Trials.

Review Methods: We retrieved all randomized controlled trials comparing at least two arms of different systemic treatment regimens or a systemic regimen to no treatment in patients with CUP, excluding data on favorable subset CUP, whenever these could be separated.

Prognostic factors and outcomes for osteosarcoma: an international collaboration.

We aimed to evaluate the prognostic significance of traditional clinical predictors in osteosarcoma through an international collaboration of 10 teams of investigators (2680 patients) who participated. In multivariate models the mortality risk increased with older age, presence of metastatic disease at diagnosis, development of local recurrence when the patient was first seen, use of amputation instead of limb salvage/wide resection, employment of unusual treatments, use of chemotherapeutic regimens other than anthracycline and platinum and use of methotrexate. It was also influenced by the site of the tumour.
