Treatment of locally advanced breast cancer with neoadjuvant chemotherapy assesses an in vivo tumor response while increasing breast conservation. Axillary clearance of nodal disease after treatment defines prognostic stratification. Our study objective was to show that sentinel node staging before treatment can optimize posttreatment prognostic stratification in clinically N0 patients. ⋯ This study validates the prognostic stratification of patients with a complete pathologic axillary response to neoadjuvant chemotherapy. The addition of SLN biopsy to cN0 patients before treatment increased accurate nodal staging by 53%, eliminated completion axillary lymph node dissection in 15%, and demonstrated an improved prognosis in 28% of pCRAX patients. SLN biopsy before treatment provides accurate staging of cN0 patients; allows acquisition of standard treatment markers, prognostic biomarkers, and microarray analysis; and affords prognostic stratification after treatment.

The reported data on surgery plus radiotherapy for retroperitoneal soft tissue sarcomas (RPS) have been mostly from retrospective studies. We evaluated the long-term outcome of patients with operable RPS who were treated with protocol-based preoperative radiotherapy followed by complete surgical resection. ⋯ Patients with intermediate- or high-grade RPS treated with preoperative radiotherapy plus complete resection had a median survival >60 months. This compares favorably to historical data for similar patients treated with surgery alone.

Few data exist regarding outcomes after resection versus embolic treatment of symptomatic metastatic carcinoid and neuroendocrine tumors. The purpose of this study was to determine whether cytoreduction provides any benefit over embolic management of diffuse neuroendocrine tumors. ⋯ Cytoreduction for metastatic neuroendocrine tumors resulted in improved symptomatic relief and survival when compared with embolic therapy in this nonrandomized study. Cytoreduction should be pursued whenever possible even if complete resection may not be achievable.
