BACKGROUND An attempt was made to improve metachronous oesophageal cancer prognosis through bi-annual systematic esophageal endoscopy screening in patients treated for head and neck cancer. PATIENTS AND METHODS Bi-annual esophageal endoscopy, without a staining procedure, was performed in 1560 patients from 1987 to 1997. The distribution of previous head and neck cancer was oral cavity (20%),...
BACKGROUND AND AIMS Although adenomas may be precursors to colorectal cancers (CRC), knowledge concerning the development of metachronous CRC is scarce. We assessed whether differential expression of cell-cycle and apoptosis-regulating proteins and a monotonous population of elongated cells (MPECs) in colorectal adenomas could predict metachronous CRC. METHODS Application of immunohistochemis...
Between 1970 and 1993, 446 patients underwent pneumonectomy. Completion pneumonectomy was performed in 37 patients (8.3%): 34 men and 3 women, with a mean age of 61 years (range 20-78 years). Indications were benign disease in 4 patients and carcinoma in 33. Of the latter, 21 patients underwent resection for metachronous lung cancer, 6 for recurrent lung cancer, 4 for previous incomplete resect...
Introduction. Giant cell tumors (GCTs) of bone are known for their local aggressiveness and high recurrence rate. There are rare cases of multicentric GCT and most are synchronous. We herein review metachronous multicentric GCT reported in the literature. Material and Methods. A MEDLINE, Cochrane, and Google Scholar search was done to collect all cases of multicentric metachronous GCT specifyin...
Background It is known that metachronous colorectal cancer risk for Lynch syndrome patients with primary colon cancer is high and total colectomy is the preferred option [1]. However if the index primary cancer is in the rectum, management advice is complicated by considerations of worsening bowel function or stoma formation. To aid surgical decision-making, we estimated the risk of metachronou...
We recently published in your journal a 3-year multicentre prospective cohort study demonstrating the usefulness of an epigenetic cancer risk marker for gastric metachronous cancers. This study achieved the first proof of concept of epigenetic cancer risk diagnosis in any type of cancer but, due to the short follow-up period, a relatively small number of events were observed, resulting in a mar...
Cancer stem cells have tumor-initiation and tumor-maintenance capabilities. Stem-like cells are present in colorectal adenomas, but their relationship to adenoma pathology and patient characteristics, including metachronous development of an additional adenoma ("recurrence"), has not been studied extensively. We evaluated the expression of aldehyde dehydrogenase isoform 1A1 (ALDH1A1), a putativ...
BACKGROUND/AIMS Colorectal adenomas that are ≥10 mm have villous histology or high-grade dysplasia, or that are associated with ≥3 adenomas are considered high-risk for metachronous advanced neoplasia. We evaluated the cumulative incidence of metachronous advanced neoplasia according to the total number of high-risk findings detected on baseline colonoscopy. METHODS This was a retrospective c...
