Résumé

PURPOSE: To evaluate the pathological and clinical effects of preoperative chemoradiation (CCRT) in cases of locally advanced rectal cancer and to determine the predictive factors for tumor downstaging. MATERIALS AND METHODS: From March 2004 to August 2008, 33 patients with locally advanced rectal cancer were treated with preoperative CCRT. Twenty-eight patients (84.8%) were treated using a concomitant boost technique while five (15.2%) patients were treated using a cone down boost technique. All patients received 50.4 Gy of irradiation and concurrent chemotherapy with 5-fluorouracil. The median follow-up duration was 24.2 months (range, 9.8 to 64.7 months). RESULTS: Thirty-one (93.9%) patients underwent surgery. Twenty-four patients (72.7%) underwent anal sphincter-preserving surgery. The 3-year disease free survival (DFS) and overall survival rates were 63.4% and 78.8%, respectively. Post-operative factors were more important for DFS. Pathologic N stage, margin status, and pathologic differentiation were significant prognostic factors (p=0.001, 0.029, 0.030). Tumor size and lymphovascular invasion were also associated with marginal significance (p=0.081, 0.073). However, only pre-treatment T stage was a significant pre-operative factor (p=0.018). The complete pathological response rate was 9.1%. T-downstaging was observed in ten (30.3%) patients, whereas N-downstaging was found in 24 (72.7%) patients. Pre-treatment T stage and the interval between CCRT and operation were the predictive factors for downstaging in a univariate analysis (p=0.029, 0.027). Pre-treatment carcinoembryogenic antigen was also associated with marginal significance (p=0.068). CONCLUSION: The survival of rectal cancer patients can be better determined based on post-operative findings. Therefore, pre-operative CCRT for downstaging of the tumor seems to be important. Pre-treatment T stage and the interval between CCRT and operation can be used to predict downstaging.

Résumé

PURPOSE: The purpose of this study is to develop a set of standardized nursing interventions and their associated nursing activities according to the NIC system to guide home care nurses in performing nursing intervention activities for hospice patients. METHOD: This study was a descriptive survey that first identified frequently used & specialized hospice nursing interventions based on the NIC systems and next validated a set of standardized nursing interventions and their associated nursing activities. One hundred chart records of home hospice patients were used to identify nursing interventions. Also, thirty-nine hospice specialized nurses participated twice using the Delphi technique to test the content validity of the standards. RESULTS: Among the nursing interventions, 19 important nursing interventions and 418 associated nursing activities were selected after two rounds of Delphi technique by hospice specialized nurses. The mean content validity of the final nursing activities was 0.82. In this paper, only the 3 most frequently used nursing interventions and 3 hospice specialized nursing interventions with their associated nursing activities are presented since space is limited. CONCLUSION: The nursing intervention standards will be a basis for home hospice nurses to improve quality of hospice care for hospice patients.
