to define efficacy of pre-operative chemotherapy in down staging of advanced non-round cell soft tissue sarcomas. from sep 2002 to dec 2005, 70 patients were treated by ifosfamid, mesna, cisplatin, adriamycin, mitomycin and subsequent surgery. postoperatively, patients received radiotherapy in cases of microscopically incomplete resection or local recurrence. the median age of the patients was ...

background: today the use of laparoscopy before laparotomy is an effective method for decision-making in patients with gastric adenocarcinoma. the reliance on ct scans for decision-making purposes is not only unhelpful, yet also misleading . nonetheless, indications for laparoscopy and its application are changing daily. the low quality of diagnostic tools and epidemiological situation in our c...

objectives: multidrug resistance (mdr), which may be due to the over expression of p-glycoprotein (pgp) and/or mrp, is a major problem in neoadjuvant chemotherapy of osteosarcoma. the aim of this study was to investigate the role of tc-99m mibi scan for predicting the response to pre-operative chemotherapy. materials and methods: twenty-five patients (12 males and 13 females, aged between 8 and...

background : this prospective study assessed the efficacy of neoadjuvant and adjuvant chemotherapy on patients with high risk soft tissue sarcomasof the extremities. methods : enrolled patients received the following neoadjuvant chemotherapy: doxorubicin (75 mg/m2) on day1, ifosfamide (2.5 g/m2/d) and mesna (20% of the ifosfamide dose) from days1 to 3, repeated every three weeks for a total of ...

Background: Gastric cancer is an important health problem across the world. Chemotherapy in combination with local treatment is standard treatment for locally advanced gastroesophageal cancers. The purpose of this investigation was evaluation of response and tolerability to neoadjuvant EOX regimen in locoregionally advanced gastric cancer. Materials and Methods: patients with locoregionally adv...

BACKGROUND The significance of neoadjuvant chemotherapy followed by definitive surgery for sinonasal squamous cell carcinoma (SCC) was investigated using surgical specimens. METHODS Surgery was performed in 58 patients, including 43 patients who had received neoadjuvant chemotherapy. The pathological response was classified as grades 0 (no effect), 1 (slight effect), 2 (moderate effect), and ...

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,...

Introduction: Esophageal cancer is an invasive and fatal malignancy, with the highest global incidence in southern and eastern Africa and eastern Asia. Patients with advanced localized disease and poor prognosis face a five-year survival rate of 15% to 34%. The research is aimed at evaluating Different strategies have been done to treat esophageal cancer by meta-analysis. <str...
