BACKGROUND To evaluate the contribution of chemotherapy for patients with locoregionally advanced nasopharyngeal carcinoma (NPC) treated by intensity modulated radiotherapy (IMRT) and to identify the optimal combination treatment strategy. PATIENTS AND METHODS Between 2006 and 2010, 276 patients with stage II-IVb NPC were treated by IMRT alone or IMRT plus chemotherapy. Cisplatin-based chemot...

Several studies have evaluated the efficacy of neoadjuvant treatment using oxaliplatin and fluoropyrimidines in advanced gastric cancer (GC). However, preoperative biomarkers predictive of clinical outcome remain lacking. We examined polymorphisms in the MTHFR, DPYD, UMPS, ABCB1, ABCC2, GSTP1, ERCC1, and XRCC1 genes to evaluate their usefulness as pharmacogenetic markers in a cohort of 103 GC p...

The past few decades have seen an increase in both the role and the complexity of neoadjuvant therapy for breast cancer. Neoadjuvant therapy was initially described as systemic chemotherapy for inflammatory or locally advanced breast cancer but now entails a combination of chemotherapy, endocrine therapy, and targeted therapy. Neoadjuvant systemic therapy is employed for inoperable inflammatory...

PURPOSE Gene expression analysis identifies several breast cancer subtypes. We examined the relationship of neoadjuvant chemotherapy response to outcome among these breast cancer subtypes. EXPERIMENTAL DESIGN We used immunohistochemical profiles [human epidermal growth factor receptor 2-positive (HER2+)/hormone receptor-negative for HER2+/estrogen receptor-negative (ER-), hormone receptor and...

BACKGROUND Several non-randomised trials have shown that transitional-cell carcinoma of the bladder is a moderately chemosensitive tumour. We investigated whether the addition of neoadjuvant cisplatin-based chemotherapy to radical surgery or radiotherapy would improve survival. METHODS Patients with T2 G3, T3, T4a, N0-NX, or M0 transitional-cell carcinoma of the bladder undergoing curative cy...

We analyzed the improvement of survival time and the effects of neoadjuvant chemotherapy combined with radiotherapy on treating patients with advanced esophageal carcinoma. Retrospectively, 43 patients were selected with esophageal carcinoma who were administered neoadjuvant chemotherapy combined with radiotherapy. According to gender, and tumor staging, the nearest neighbor matching was carrie...

BACKGROUND: Recent prospective data demonstrate that stereotactic body radiation therapy (SBRT) is safe and effective in locally advanced pancreatic cancer (LAPC); however, little is known regarding the role of SBRT in the neoadjuvant setting. This study compared the role of neoadjuvant chemotherapy with and without SBRT in patients with borderline resectable pancreatic cancer (BRPC) or LAPC. M...

Assessment of respectability may be regarded as a key component esophageal cancer treatment. Neoadjuvant therapies considered particularly in the setting locally advanced cancer. While surgery alone adequate for selected patients, incorporation neoadjuvant or adjuvant therapeutic strategies with respect to patient, tumor, and treatment characteristics. In this study, we focused on tumor size ch...

BACKGROUND The purpose of this study was (i) to test the hypothesis that combining Ki67 with residual cancer burden (RCB) following neoadjuvant chemotherapy, as the residual proliferative cancer burden (RPCB), provides significantly more prognostic information than either alone; (ii) to determine whether also integrating information on ER and grade improves prognostic power. PATIENTS AND METH...

Background The aims of this study were to determine whether the quantitative HER2 gene amplification level is related to the key clinicopathological features that represent the aggressiveness of breast cancer (BC) and to determine whether the quantitative HER2 gene amplification level could predict the treatment response in the subset of HER2-positive patients who received neoadjuvant targeted ...
