Background: In recent years, neoadjuvant chemoradiation and subsequent surgical resection with total mesorectal excision has been shown to increase local control with decreased toxicity. Neoadjuvant chemoradiotherapy is the standard treatment for locally advanced rectal cancer. In this study we evaluated the efficacy a cox-2 inhibitor on pathologic response, sphincter preservation and acute tox...

BACKGROUND Epithelial ovarian cancer (EOC) accounts for 25% of all malignancies in the female genital tract and it is the most common cause of death among women who develop gynecologic malignancies. According to recent reports at least 20% of EOC are diagnosed at stage I of the disease. Because women tend to give birth to their first child at an older age, and due to the usage of more sensitive...

Objective: Prediction of responders to induction therapy in esophageal cancer (EC) patients is important. In this study, we evaluated the role of thoracoscopic/laparoscopic (Ts/Ls) staging in prediction of treatment response and survival in EC patients with trimodality treatment. Methods: Retrospective study of EC patients who had undergone Ts/Ls staging and received trimodality treatment at th...

BACKGROUND Several extrathoracic tumors metastasize to the mediastinum. Mediastinoscopy is the standard method to obtain tissue proof of mediastinal spread, but drawbacks are its invasiveness, requirement for general anesthesia and costs. Transesophageal endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is indicated in lung cancer staging guidelines as a minimally invasive alternati...

We have developed new clinical (C) and laboratory (L) staging systems to improve the clinical management of chronic lymphedema. These systems were retrospectively assessed in 220 chronic lymphedema patients followed up for 4 years. Clinical evaluation of the treatment response/disease progression was performed at 6 month intervals and laboratory evaluation at a yearly interval except for recurr...

Positron emission tomography with 18F-fluoro-2-deoxy-d-glucose (FDG-PET) is more accurate than computed tomography for staging of mediastinal (hilar) lymph nodes. In the case of positive findings, tissue sampling of lymph nodes is required. The diagnostic/staging yield of transbronchial needle aspiration (TBNA) following endobronchial ultrasound (EBUS) localisation was assessed in this particul...

BACKGROUND Diagnostic performance of Diffusion-Weighted magnetic resonance Imaging (DWI) and Multi-Detector Computed Tomography (MDCT) for TNM (Tumor, Lymph node, Metastasis) staging of gastric cancer was compared. PATIENTS AND METHODS We used axial T2-weighted images and DWI (b-0,400 and b-800 s/mm2) protocol on 51 pre-operative patients who had been diagnosed with gastric cancer. We also co...
