PURPOSE The excision repair cross-complementing 1 (ERCC1) gene is coding for a nucleotide excision repair protein involved in the repair of radiation- and chemotherapy-induced DNA damage. We examined the potential of quantitative ERCC1 mRNA expression to predict minor or major histopathological response to neoadjuvant radiochemotherapy (cisplatin, 5-fluorouracil, and 36 Gy of radiation) followe...
BACKGROUND Several grading schemes for the extent of residual tumor in posttreatment pancreaticoduodenectomy (PD) specimens have been proposed. However, the prognostic significance of these grading schemes is unknown. METHODS Histopathologic slides of 223 cases who received neoadjuvant chemoradiation and PD were reviewed. The extent of residual tumor was graded using both the College of Ameri...
BACKGROUND Five-year survival rates among stage IIIA lung cancer patients range between 2% and 15%, and there is currently no consensus regarding optimal treatment approaches for these patients. The current investigation evaluated survival outcomes among stage IIIA lung cancer patients receiving 2 different treatment modalities, neoadjuvant chemotherapy followed by resection versus chemoradiati...
BACKGROUND Cyclin D1 (CCND1) has been associated with chemotherapy resistance and poor prognosis. In this study, we tested the hypothesis that CCND1 expression determines response and clinical outcomes in locally advanced head and neck squamous cell carcinoma (HNSCC) patients treated with neoadjuvant chemotherapy followed by surgery and radiotherapy. METHODOLOGY AND FINDINGS 224 patients with...
PURPOSE We sought to systematically define determinants of the response to neoadjuvant chemotherapy to elucidate predictive biomarkers for breast cancer. EXPERIMENTAL DESIGN An unbiased systematic analysis was performed in multiple independent datasets to define genes predictive of complete pathologic response (pCR) following treatment with neoadjuvant chemotherapy. These genes were interroga...
BACKGROUND Anti-angiogenesis is a promising therapeutic strategy for locally advanced breast cancer. We performed this phase II trial to evaluate the anti-angiogenesis and anti-tumor effect of rh-endostatin combined with docetaxel and epirubicin in patients with locally advanced breast cancer by dynamic contrast-enhanced magnetic resonance imaging in 70 previously untreated locally advanced bre...
PURPOSE The association between PIK3CA mutations and response to neoadjuvant chemotherapy in women with primary breast cancer is not fully elucidated. EXPERIMENTAL DESIGN PIK3CA mutations in breast cancer tissues that were taken prior to the initiation of neoadjuvant chemotherapy were identified in 729 operable primary breast cancer patients who received neoadjuvant chemotherapy. Among these,...
Respiratory complication is one of the important postoperative complications of oesophageal cancer. The aim of this study was to evaluate whether neoadjuvant chemotherapy before surgery is effective for postoperative respiratory complications. In this study, patients with oesophageal cancer were divided into two group: one with neoadjuvant therapy and the other without neoadjuvant therapy. Befo...
methods study on 34 patients diagnosed with rectal adenocarcinoma referred to oncology clinic was conducted. the treatment plan included 4050 cgy radiotherapy and 5fu, xeloda chemotherapy. all patients were assessed with 1/5 t mri 6 to 8 weeks after treatment. t1 and t2 images with sagittal, cronal and axial planes with and without contrast agent were obtained and interpreted by two radiologist...
