4004 Background: The optimum combination curative approach to locally advanced adenocarcinoma of the esophagus and esophago-gastric junction (AEG) is unknown. A key question whether neoadjuvant multimodal therapy, specifically CROSS (carboplatin/paclitaxel, 41.4Gy radiation therapy), superior peri-operative chemotherapeutic regimens including modified MAGIC (epirubicin, cisplatin (oxaliplatin), 5-FU (capecitabine)) more latterly FLOT (docetaxel, 5-FU, leucovorin, oxaliplatin). Neo-AEGIS was...

LBA3514 Background: Organ preserving treatment strategies based on chemoradiotherapy may spare rectal cancer patients of major surgery and stoma. We suggest substantially improved tumor control by increasing the radiotherapy dose, without significant increase in rate late effects. designed a prospective phase II trial to test high-dose low for organ preservation multicenter setting. Methods: enrolled with localized T1-3 N0-1 M0 within 6 cm from anal verge performance status 0-2. Any N1-nodes...

Introduction. In patients with advanced ovarian cancer undergoing preoperative PET/CT, we investigated the prognostic value of SUV in primary tumor and evaluated for predicting incomplete cytoreduction (macroscopic residual tumor). Material methods. From September 2004 to August 2007, 201 consecutive a pelvic Risk Malignancy Index (RMI) > 150 based on serum CA-125, ultrasound examinations menopausal state, underwent PET/CT within two weeks prior standard surgery/debulking tumor. At two-year...

To evaluate the role of 2-deoxy-2-(F)fluoro-D-glucose (FDG) positron emission tomography/computed tomography (PET/CT) for selecting patients with extensive ovarian cancer (OC) neoadjuvant chemotherapy by evaluating predictors overall survival in stage IIIC/IV OC.From September 1, 2004, to November 20, 2011, 514 consecutive a pelvic tumor underwent preoperative PET/CT; 179 had OC. Patients' characteristics were collected from 153 OC who primary surgery. In 152 OC, clinical and PET/CT...

Abstract Purpose: To determine if the level of apolipoprotein A1, hepcidin, transferrin, inter‐α trypsin IV internal fragment, transthyretin (TT), connective‐tissue activating protein 3 (CTAP3), serum amyloid β‐2 microglobulin (B2M) might have impact on overall and progression‐free survival for ovarian cancer (OC) patients. Experimental design: Serum from 150 OC patients was tested using SELDI‐TOF‐MS. Results: A proteomic prognostic index (xb‐pro) constructed regression coefficients based...

The objective of this prospective study was to evaluate CA-125 and a 7-marker panel as predictors incomplete primary cytoreduction in patients with stage III/IV ovarian cancer (OC). From September 2004 January 2008, serum from 201 referred surgery for pelvic tumor analyzed CA-125. In addition, 7 biomarkers using surface-enhanced laser desorption/ionization time-of-flight mass spectrometry. These were combined into single-valued ovarian-cancer-risk index (OvaRI). OvaRI evaluated 75 receiver...

ObjectivesIn a randomized phase II trial, twice daily (BID) thoracic radiotherapy (TRT) of 60 Gy/40 fractions improved survival compared with 45 Gy/30 in limited stage small-cell lung cancer (LS SCLC). Notably, the higher dose did not cause more toxicity. Here we present health related quality life (HRQoL) reported by trial participants during first 2 years.Materials and methods170 patients were 1:1 to TRT Gy or concurrently cisplatin/etoposide chemotherapy. The 150 who commenced completed...
