This study examined the association between 17p allelic loss, p53 gene mutation, p53 protein expression and DNA aneuploidy in a series of adenocarcinomas arising in the oesophagus and gastric cardia. 17p allelic loss was detected in 79% (15 of 19) of oesophageal and in 83% (29 of 35) of gastric adenocarcinomas. p53 mutations were detected in 70% (14 of 20)(More)
To identify chromosomal loci involved in the development of proximal gastric adenocarcinoma, this study delineated the pattern of allelic imbalance in a series of 38 adenocarcinomas arising in the gastric cardia. A total of 137 microsatellite markers covering all autosomal arms, excluding acrocentric arms, were analysed. A mean of 35 out of a total of 39(More)
OBJECTIVES This study compares the posterior auscultatory triangle thoracotomy incision (muscle sparing) with full posterolateral thoracotomy (where latissimus dorsi muscle is always cut across its full width), with particular attention to the difference between latissimus dorsi muscle strength, post operative pain and chronic wound related symptoms.

Microsatellite alterations have been documented in a subset of sporadic tumors, including those of the colon, lung, bladder, stomach, and esophagus. This study documented the frequency of microsatellite alterations at 139 loci, comprising predominantly dinucleotide and tetranucleotide repeat units, in 17 cases of primary esophageal adenocarcinoma arising(More)
BACKGROUND The issue of performing simultaneous pulmonary resection and cardiac surgery in patients with coexisting lung carcinoma and ischaemic heart disease remains controversial. We report our experience and review the literature. METHODS Thirteen patients (male ten, female three; mean age 65 years) underwent simultaneous cardiac surgery and pulmonary(More)
BACKGROUND Tumor angiogenesis is critical for metastasis development. The detection of bone marrow micrometastases may indicate a metastatic phenotype. We aim to establish if the detection of bone marrow micrometastases associates with elevated markers of angiogenesis and adverse histopathologic features of esophageal cancer. METHODS Bone marrow aspirates(More)
BACKGROUND Sputum retention after lung operation is a potentially life-threatening condition. The minitracheostomy (Minitrach II, SIMS Portex, Hythe, Kent, UK) is a 4-mm percutaneous cricothyroidotomy device, which allows immediate and repeated aspiration of the tracheobronchial tree by minimally trained staff, and can effectively treat sputum retention.(More)
Descending necrotising mediastinitis can complicate oropharyngeal infection and has a high associated mortality. We present three cases treated in our department and propose a treatment algorithm based on our experience and literature review. The primary oropharyngeal infection was peritonsillar abscess in two cases and odontogenic abscess in one. Two(More)
Detection of bone marrow micrometastases (BMMs) in patients with esophageal carcinoma may indicate a metastatic phenotype. We assessed if the presence of BMMs had adverse prognostic significance in a 10-year follow-up study. Patients undergoing surgery for esophageal cancer were prospectively recruited between February 1999 and August 2000. Bone marrow(More)
