Lymph node metastasis in lower lip squamous cell carcinoma in relation to tumour size, histologic variables and p27Kip1 protein expression.
We studied a consecutive series of 95 patients undergoing radical surgical resection of lower lip squamous cell carcinoma (LLSCC) to assess the correlation between lymph node status and several prognostic variables, such as sex and age, tumour size, histologic grading, maximal microscopic tumour thickness, perineural infiltration and p27Kip1 protein status, to see which of these might be predictive of the development of lymph node metastases. Statistical analysis demonstrated a significant association between node status and tumour size, histological grading, maximal thickness, perineural invasion and p27Kip1 protein expression; additionally to node metastasis, low p27Kip1 protein expressio…
Overexpression of cyclin D1 and interaction between p27Kip1 and tumour thickness predict lymph node metastases occurrence in lower lip squamous cell carcinoma
We have attempted to identify those subgroups of patients most likely to develop lymph node metastases from squamous cell carcinoma of the lower lip (LLSSC). A total of 97 subjects, who did not undergo elective neck dissection, were recruited into the 60-month disease-free survival study. After univariate analysis, tumour size, histological grading, maximal thickness, perineural invasion and immunoreactivity to cyclin D1 and p27Kip1 proteins proved to be significant factors. Tests of the effect of interaction between p27Kip1 LI and tumour thickness yielded that the impact of tumour thickness on the risk of lymph node metastases was modified by the percentage of p27Kip1 positive cells. Subse…
Evidence-Based Knowledge Management: an approach to effectively promote good health-care decision-making in the Information Era.
The sharing of information and the growth of knowledge together represent a foundation for the promotion of quality improvement of health care systems. This paper concerns knowledge, not only from an epistemological point of view, but also from a pragmatic one. In our paper, knowledge is discussed as the hub to promote better decision making and continuous professional development. Effective thinking is particularly needed. The critical point is to think about how health care systems can develop both an effective knowledge management network and how health-care organizations can actually be based on it. In this way, knowledge and knowledge hierarchy are defined according to Russel Achkoff's…
