Koinzidenz von Plattenepithelkarzinomen der Speiseröhre und Kopf-Hals-Karzinomen: Risiko und Früherkennung

2007

Patients suffering from head and neck cancer (HNC) have or will develop a second esophageal squamous cell cancer (ESCC) in 5 - 14 %. When a second esophageal neoplasm occurs in a HNC patient, the prognosis is generally determined by the ESCC, and unfortunately it is poor. Prospective clinical studies in Japan, Brazil, Taiwan, France and Germany have shown that screening or surveillance using Lugol chromoesophagoscopy enables early detection of second esophageal neoplasias. Such a surveillance results in a survival benefit for HNC patients. Vice versa, ESCC patients also have a risk of 9.3 - 11.4 % for a head and neck cancer. Periodic otolaryngeal examination and pharyngoscopy is recommended…

Maximum likelihood ADC parameter estimates improve selection of metastatic cervical nodes for patients with head and neck squamous cell cancer

2012

The aim of this work was to determine whether classification of benign and metastatic cervical nodes based on diffusion weighted imaging (DWI) could be improved by use of a maximum likelihood algorithm for derivation of ADC parameters. A non linear least squares (LSQ) algorithm is usually used to fit parameters to the measured MR signal intensities as a function of b-value. LSQ assumes that the noise in high b-values is normally distributed whereas in reality it follows a Rice distribution. To account for the Rician noise, maximum likelihood (ML) algorithms have been proposed that provide unbiased ADC estimates. In this work the monoexponential, stretched exponential and biexponential model…

POWER: An open-label, randomized phase III trial of cisplatin and 5-FU with or without panitumumab (P) for patients (pts) with nonresectable, advance…

2013

TPS4158 Background: More than 50% of pts with esophageal cancer have locally advanced or metastatic disease at the time of initial diagnosis. For this group chemotherapy is increasingly used intending local and distant tumor control, improvement of quality of life (QoL) and longer survival. Previous data suggested that EGFR-targeting antibodies may be safely combined with cisplatin and 5-FU, and in addition may increase the efficacy of the standard cisplatin/5-FU regimen [Lorenzen et al, Ann Oncol2009; 20(10): 1667-1673]. Methods: In this open-label, randomized (1:1), multicenter, multinational phase III trial pts with nonresectable, advanced or metastatic ESCC, not eligible for definitive…

Nal-IRI/LV5-FU versus paclitaxel as second-line therapy in patients with metastatic esophageal squamous cell carcinoma (OESIRI)-PRODIGE 62: A multice…

2020

Half of patients newly diagnosed with esophageal squamous cell cancer (ESCC) have metastatic disease (mESCC) and therefore a poor prognosis. Furthermore, half of patients with initial loco-regional disease present disease recurrence after surgery and/or chemoradiation. In mESCC, the recommended first-line treatment combines 5-fluorouracil and cisplatin, although this has not been validated by a phase III trial. Patients with disease progression or recurrence after platinum-based chemotherapy and good performance status probably benefit from second-line chemotherapy. Several molecules have been evaluated in phase I/II trials or retrospective studies (docetaxel, paclitaxel and irinotecan) but…

Diagnosing early Barrett’s neoplasia and oesophageal squamous cell neoplasia by bioimpedance spectroscopy in human tissue

2013

Background: Detection of early oesophageal cancer in surrounding normal tissue can be challenging, but detection is essential to determine the subsequent treatment. Dysplastic tissue can be detected by using electrical impedance spectroscopy (EIS). Objective: The aim of the present study was to evaluate the feasibility and value of EIS in the diagnosis of oesophageal neoplasia. Methods: This prospective ex-vivo study included 23 patients with early oesophageal cancer (17 with Barrett’s cancer and six with early squamous cell cancer). Immediately after endoscopic resection, the electrical properties of the resected specimens were investigated using a pencil probe (5 mm in diameter, frequency…
