Neoadjuvant Therapy for Resectable and Borderline Resectable Pancreatic Cancer
The majority of patients with localized pancreatic cancer (PC) who undergo surgery followed by adjuvant therapy will develop metastatic disease, suggesting that surgery alone is not sufficient for cure and micrometastases are present even when are not clinically detected. As such, the delivery of early systemic therapy may be a rational alternative to a surgery-first approach, in an effort to p...
متن کاملNeoadjuvant therapy for resectable pancreatic cancer
The use of neoadjuvant therapies has played a major role for borderline resectable and locally advanced pancreatic cancers (PCs). For this group of patients, preoperative chemotherapy or chemoradiation has increased the likelihood of surgery with negative resection margins and overall survival. On the other hand, for patients with resectable PC, the main rationale for neoadjuvant therapy is tha...
متن کاملNew tumor regression grade for rectal cancer after neoadjuvant therapy and radical surgery
In this retrospective study, we defined a new tumor regression grade (NTRG), which we used to evaluate the prognosis of patients with locally advanced rectal cancer who received neoadjuvant therapy and then underwent radical surgery between June 2004 and October 2011. Calculated as the TRG plus a lymph node score, the NTRG was determined for 347 patients: NTRG 0, 46 patients (13.3%); NTRG 1, 63...
متن کاملComparison of 1-, 2-, and 3-Dimensional Tumor Response Assessment After Neoadjuvant GTX-RT in Borderline-Resectable Pancreatic Cancer.
BACKGROUND Facilitation of margin-negative resection is the goal of neoadjuvant therapy regimens used in the treatment of borderline-resectable pancreatic cancer patients. Multiple treatment approaches have shown efficacy in this setting, including neoadjuvant GTX (gemcitabine [Gemzar], docetaxel [Taxotere], and capecitabine [Xeloda]) and radiotherapy (RT). Three-dimensional tumor response may ...
متن کاملBorderline resectable pancreatic cancer.
Rigorous criteria to define "borderline resectable" pancreatic cancer are required for appropriate patient accrual into clinical trials that examine the utility of chemotherapy and/or chemoradiation that will be delivered prior to pancreatic resection for exocrine cancer. At our institution, tumor abutment of less than or equal to 180 degrees (< or = 50% of the vessel circumference) of the supe...
