Very few cases have been reported to be located in the small intestine. Here we report the first case located in the jejunum in a patient who was diagnosed with a colonic adenocarcinoma. In the preoperative evaluation this benign lesion was thought it might represent a metastatic nodule.展开更多

Study design: The examined material included 43 cases with coexistent CIN1 and CIN3 in the cone biopsy specimen. Detection and typing of HPV was made by RFLP-PCR. Results: All CIN1 lesions were HPV positive, while three CIN3 lesions were HPV-negative. The proportion of agreement of the HPV type in the two lesions, excluding negative cases (n = 40), was 60% (95% confidence interval: 43.3-75.1). HPV 16 was the most common type in both CIN3 (56.8% ) and CIN1 (46.5% ). Conclusions: The so-called morphologic progression of CIN is not always synonymous with biologic progression, since many coexistent CIN lesions are caused by different HPV types, and so represent different cell clones. Clonality of coexistent CIN lesions may be implicated in the evolution of CIN as other recent studies have shown.展开更多

METHODS: Patients enrolled in the "liver first" protocol presented with colon-only(not rectal) cancer and multiple synchronous hepatic metastases(type Ⅱ or Ⅲ). All patients showed good performance status(ECOG PS 0-1) and were treated with curative intent. Complete oncologic staging including positron emission tomography-computed tomography was performed in order to rule out extrahepatic disease. If bowel obstruction was imminent, an intraluminal colonic stent was placed endoscopically. Subsequently, all patients received standardised neo-adjuvant chemotherapy, that is, FOLFOX or XELOX regimens combined with an antiangiogenic agent(bevacizumab or cetuximab). Provided that a response to chemotherapy was observed, patients underwent either one or two hepatectomies with or without portal vein embolization followed by the indicated colectomy. Further chemotherapy was administered after each procedure. Re-staging was performed after each chemotherapeutic treatment. Disease progression at any stage resulted in discontinuation of the protocol and conversion to palliative disease management.RESULTS: Prospectively recorded data from 11 consecutive patients(8 men) were analysed for this study. Their mean age at the time of their first assessment was 65.7(SD ± 15.3) years. Six(54.6%) patients presented with type Ⅲ metastatic disease. The minimum and maximum follow-up periods were 7.3 and 39.6 mo, respectively. The mean overall survival of all patients was 16.5(95%CI: 10.0-23.2) mo. A colonic stent had to be placed in 5(45.5%) patients due to the onset of an intraluminal obstruction. Four(36.4%) patients succeeded in completing all planned surgical operations. Their mean overall survival was 27.2(95%CI: 15.1-39.3) mo and the mean disease-free survival was 7.7(95%CI: 3.0-12.5) mo. Patients, who were obliged to shift to palliative treatment due to dis-ease progression, had a mean展开更多
