Neoadjuvant chemoradiation and chemotherapy provided for borderline or locally advanced, potentially resectable pancreatic adenocarcinoma improves resectability rates. Response to therapy is also an important prognostic factor. There are no data in the literature regarding optimal time interval or duration of chemotherapy after chemoradiation before surgery, and pathologic response rates. Using our database, we evaluated these relationships and the effect on overall and progression-free survival. ⋯ Patients who underwent a prolonged time interval after neoadjuvant chemoradiation with ongoing chemotherapy were more likely to have an improved pathologic response at time of surgical resection, which was associated with improved median overall survival.

Review Meta Analysis
Value of preoperative ultrasound-guided axillary lymph node biopsy for preventing completion axillary lymph node dissection in breast cancer: a systematic review and meta-analysis.
This meta-analysis was designed to evaluate the utility of preoperative axillary ultrasound combined with US-guided lymph node biopsy if indicated (AUS ± biopsy), in terms of staging the axilla and preventing two-step axillary surgery in the form of sentinel node biopsy (SNB) followed by completion axillary lymph node (ALN) dissection. ⋯ Preoperative axillary ultrasound-guided biopsy is a useful step in the process of axillary staging. Approximately 50 % of women with axillary involvement can be identified preoperatively. Still, one in four women with an ultrasound-guided biopsy-"proven" negative axilla has a positive SNB.

Management of metastatic spine disease is quite complex. Advances in research have allowed surgeons and physicians to better provide chemotherapeutic agents that have proven more efficacious. Additionally, the advancement of surgical techniques and radiosurgical implementation has altered drastically the treatment paradigm for metastatic spinal disease. Nevertheless, the physician-patient relationship, including extensive discussion with the neurosurgeon, medicine team, oncologists, radiation oncologists, and psychologists, are all critical in the evaluation process and in delivering the best possible care to our patients. The future remains bright for continued improvement in the surgical and nonsurgical management of our patients with metastatic spine disease. ⋯ Surgical oncology is a diverse field in medicine and has undergone a significant paradigm shift over the past few decades. This shift in both medical and surgical management of patients with primarily metastatic tumors has largely been due to the more complete understanding of tumor biology as well as due to advances in surgical approaches and instrumentation. Furthermore, radiation oncology has seen significant advances with stereotactic radiosurgery and intensity-modulated radiation therapy contributing to a decline in surgical treatment of metastatic spinal disease. We analyze the entire spectrum of treating patients with metastatic spinal disease, from methods of diagnosis to the variety of treatment options available in the published literature.

For breast-conserving surgery, the method of margin assessment that most frequently achieves negative margins without increasing the volume of tissue excised is uncertain. We examined our institutional experience with three different margin assessment methods used by six experienced breast surgeons. ⋯ Although the cavity-shave method may decrease the rates of positive margins, its effect on volume is variable among surgeons and may result in an increase in the total volume excised for some surgeons and for small tumors without EIC.

Comparative Study
Video-assisted thoracoscopic surgical thymectomy to treat early thymoma: a comparison with the conventional transsternal approach.
For thymoma, the feasibility of resection via video-assisted thoracoscopic surgery (VATS) remains controversial. The objective of our study was to compare the outcomes of VATS and transsternal thymectomy in order to evaluate the efficacy of the VATS method for treatment of early stage thymoma. ⋯ In early stage thymoma, VATS thymectomy associated with shorter hospital LOS and shorter duration of pleural drainage compared with the conventional transsternal approach. Otherwise, the two approaches had similar oncologic outcomes during the mean 60-month follow-up period.
