The three methods investigated in this study show comparable feasibility, clinical utility, lack of severe complications and margin of patient safety under the conditions of a secondary academic teaching hospital.
Study Design: Biopsies from the oral cavity were divided into 5 groups: (1) normal mucosa, (2) chronic inflammation, (3) mild dysplasia from leukoplakic lesions, (4) mild dysplasia in surgical margins of patients with HNSCC, and (5) HNSCC.
In total, 15 patients with Barrett's metaplasia and 15 normal stomachs taken outside the resection margins of patients with gastric adenocarcinoma were used.
In addition to abnormal thickness and GWC measures within the lesion margin, 90% of patients (10/11) showed structural abnormalities outside the known lesion.
Nonetheless, the primary weakness of current approaches is that clinical ethics education occurs at the margins of patient care and frequently focuses on ethical issues or topics that are of current or parochial interest rather than on subjects designed to address specific weaknesses or areas in which improvement in the provision of clinical ethics services is needed.
Among the patients who underwent partial laryngectomy, local recurrence on the surgical margin of 3 patients has been confirmed.
Colorectal tissue samples were obtained with informed consent at rectosigmoid endoscopy from the sigmoid colon of 52 patients (51 83 years old) exhibiting no apparent intestinal pathology and from the normal mucosa (ie, >10 cm tumour margin) of 30 patients undergoing anterior resection (44 85 years old).
A total of 70 tissue samples were analyzed for expression by real-time RT-PCR, including 50 cancer samples and 20 normal mucosa samples taken from the resection margin of cancer patients.
Despite wide resection margins 40% of patients in our population succumbed to their sarcoma within five years.
The shortterm end points of this trial indicated similar results between the randomised groups in respect of positive resection margins, proportion of patients with Dukes' C tumours and in-hospital mortality (Guillou et al, 2005).
