BACKGROUND Most treatment failure of buccal mucosal cancer post surgery is locoregional recurrence. We tried to figure out how close the surgical margin being unsafe and needed further adjuvant treatment. METHODS Between August 2000 and June 2008, a total of 110 patients with buccal mucosa carcinoma (25 with stage I, 31 with stage II, 11 with stage III, and 43 with Stage IV classified accordi...

AIMS To determine important factors influencing recurrence after local excision of duct carcinoma in situ (DCIS) of the breast. MATERIALS AND METHODS The extent (size) in millimetres, classification (by cytonuclear grade (NHSBSP system), by extent of necrosis, and by the Van Nuys system), and excision margins of 115 cases of screen detected DCIS treated by local excision were measured. A prog...

background and aims. nano-ionomer (ni) interacts with tooth structures superficially, and there is a concern about the enamel bonding ability of mild self-etch ketac primer. this study compared the effect of different adhesive procedures (self-etching and etch-and-rinse approach) on long-term marginal microleakage of nano-filled resin-modified glass-ionomer (ni) cervical restorations. materials...

BACKGROUND The response of locally advanced breast cancer (LABC) to neoadjuvant chemotherapy (NACT) offers these patients previously treated by mastectomy, the chance for breast conservation. AIM This study aims to assess the feasibility of lumpectomy in patients with LABC treated by NACT, with residual tumor < or =5 cm. SETTINGS, DESIGN: Single group prospective study from August 2001 to Jun...

PURPOSE The aim of this study was to analyze the oncologic outcomes and the risk factors for recurrence after a tumor-specific mesorectal excision (TSME) of resectable rectal cancer in a single institution. METHODS A total of 782 patients who underwent a TSME for resectable rectal cancer between February 1995 and December 2005 were enrolled retrospectively. Oncologic outcomes included 5-year ...

CONTEXT AND OBJECTIVE Cancer of the uterine cervix is still very common in Brazil. It is important to evaluate factors that influence its prognosis. The aim here was to analyze the prevalence of prognostic anatomoclinical factors among patients with carcinoma of the uterine cervix undergoing radical hysterectomy. DESIGN AND SETTING Cross-sectional study on 301 patients with invasive carcinoma...

Question: In patients with clinical stage IIA through IIC cutaneous melanoma thicker than 2 mm, is survival different for a 2-cm local excision margin compared with a 4-cm excision margin? Design: Randomized controlled trial. The trial was not masked at any stage. Setting: Multicenter trial in 53 hospitals in 9 European centers in Sweden, Denmark, Estonia, and Norway. Patients: Patients 75 year...

OBJECTIVE One problem existing in breast-conservation surgery is ipsilateral breast tumour recurrence, and one of its major risk factors is surgical margin positivity. We therefore investigated whether total-circumference surgical margin examination can reduce surgical margin-positive rates. METHODS A total of 122 cases were examined after BCS was performed between March 2004 and March 2006. ...
