Ki-67 and p53 expression as a predictive marker for early postoperative recurrence in pancreatic head cancer

چکیده
PURPOSE This study aimed to evaluate the clinical significance of Ki-67 and p53 expressions in patients with pancreatic head cancer. METHODS Between May 2008 and April 2013, immunohistochemical staining for Ki-67 and p53 was performed in 34 patients with pancreatic head cancer (ductal adenocarcinoma). All 34 patients underwent pancreaticoduodenectomy at Chonnam National University Hwasun Hospital, Hwasun, Korea. Clinical and histopathological characteristics were analyzed, relative to p53 expression. RESULTS Thirty (88.2%) and twenty-one (61.7%) of the 34 pancreatic head cancers exhibited positive expression of Ki-67 and p53, respectively. Patients expressing Ki-67 and p53 experienced more frequent tumor recurrences within 1 year after surgical resection (P = 0.003 and P = 0.030, respectively). However, no correlation was detected between Ki-67 and p53 expression. Ki-67 expression was correlated with pathological grade, lymph node metasatsis, and clinical stage (P < 0.05). Importantly, Ki-67 was the independent predictive factor for postoperative recurrence within 1 year in both univariable and multivariable analyses (odds ratio, 27.219; 95% confidence interval, 1.403-528.135; P = 0.029). CONCLUSION The expression of Ki-67 and p53 are significantly related to early postoperative recurrence within 1 year after surgical resection in pancreatic head cancer. Especially, Ki-67 was the independent predictive factor for postoperative recurrence within 1 year. Therefore, immunohistochemical staining for Ki-67 and p53 may be applied as a predictive marker for early postoperative recurrence in pancreatic head cancer.

Background and Aim: Basal cell carcinoma (BCC) is considered to be the most common malignancy in humans and occurs primarily in the skin especially in the head and neck region. Considering the high recurrence rate of the tumor, finding a marker for prediction of recurrence is very important. Cancer stem cells are a small subpopulation in the tumors that are related to tumorigenesis and recurren...

Background: Fine-needle aspiration of breast cancer often provides moderate cellular material that is representative of the tumors. These samples can be used not only for cytological diagnosis but also to obtain information on the prognosis and likely response to therapy by using immunohistochemical staining studies. Methods: We assessed the degree of correlation between prognostic biologic ma...

Introduction & Objective: Basal cell carcinoma is the most common malignant tumor in humans. The role of ultraviolet radiation is well known in pathogenesis of BCC. More recently some immunohistochemical markers such as p53 gene and Ki-67 antigen are suggested in the pathogenesis. Some of the recent studies correlate these markers to recurrence or metastasis of the tumor. This study is done t...
