Over the past two decades, gene expression profiling of breast cancer has emerged as an important tool in early-stage breast cancer management. The approach provides important information on underlying biological mechanisms, breast cancer classification, future risk potential of developing recurrent metastatic disease, and provides beneficial clues for adjuvant chemotherapy in hormone receptor (HR) positive breast cancer. Of the commercially available genomic tests for breast cancer, the prognostic and predictive value of 21-gene recurrence score tests have been validated using both retrospective data and prospective clinical trials. In this paper, we reviewed the current evidence on 21-gene expression profiles for HR-positive HER2-negative early-stage breast cancer management. We show that current evidence supports endocrine therapy alone as an appropriate adjuvant systemic therapy for approximately 70% of women with HR-positive, HER2-negative, node-negative breast cancer. Evolving evidence also suggests that 21-gene recurrence scores have predictive values for node-positive breast cancer and that chemotherapy can be avoided in more than half of women with nodes 1 to 3 positive HR-positive breast cancer. Furthermore, retrospective data also supports the predictive role of 21-gene recurrence scores for adjuvant radiation therapy. A prospective trial in this area is ongoing. 相似文献

Current therapy: complications associated with rigid internal fixation of facial fractures 总被引:2,自引:0,他引:2

Rigid internal fixation (RIF) is commonly used for the anatomical reduction and fixation of facial fractures. This technique has many advantages over more traditional methods, such as wire osteosynthesis and maxillomandibular fixation. Properly placed RIF ensures a stable anatomical reduction and allows for immediate or early restoration of function. RIF has a number of complications associated with its use in facial trauma surgery including metal sensitivity, infection, neurologic injury, dental trauma, stress shielding, and malocclusion. Complication rates appear to be inversely proportional with operator skill and experience when using RIF. 相似文献

Objective: To assess the therapeutic results of open reduction and internal fixation with crossed K-wires via lateral approach for displaced supracondvlar fractures of the humerus in children. Methods: We prospectively followed 52 children who presented with Gartland type 3 displaced supraeondylar fractures of the humerus and were managed by open reduction and internal fixation with crossed K-wires via lateral approach.There were 37 male and 15 female patients; average age was 7.39 years. The most common mechanism of trauma was fall while playing (n=23), followed by fall from height (n=20), road traffic accidents (n-5) and fall from standing height (n=2). In 2 cases, mode of injury was not available. The mean follow-up was 12 months and patients were assessed according to Flynn's criteria. Results: Lateral approach provided an excellent view of the lateral column between two nervous planes and enabled an anatomical reduction in all cases. Immobilizing the elbow at 90 degrees or more of flexion was not needed after cross K-wire fixation. Majority of patients regained full range of motion within 6 weeks of pin removal. Two patients had postoperative ulnar nerve injuries that resolved after pin removal. The common late complication of cubitus varus was not seen in any patient. Delayed presentation to the emergency department, repeated manipulations by bone setters and massage with edible oil were responsible for stiffness in 5 patients. Superficial pin tract infection was noted in 5 patients that resolved with dressings and antibiotics. No deep infection occurred. A detailed clinical examination and radiographic analysis was done at final follow-up. They included measurement of carrying angle and range of movements of both operated and normal sides, and radiographs of both upper limbs for comparison. According to Flynn's criteria, 90.4% patients showed satisfactory results. Conclusion: Lateral approach for open reduction and internal fixation of the widely-displaced supracondylar fract 相似文献

Small cell carcinoma/neuroendocrine carcinoma (SCNEC) of the oropharynx is uncommon. Recently, an association has been reported between oropharyngeal SCNEC and high-risk human papillomavirus (HPV) infection. While HPV infection confers a better prognosis for oropharyngeal squamous cell carcinoma, HPV infection does not appear to influence the biological behaviour of SCNECs, which are generally associated with poor clinical outcomes. We document two cases of SCNEC arising in the oropharynx with evidence of high-risk HPV infection. The cases highlight the expanding range of malignant oropharyngeal neoplasms that harbour oncogenic HPV infection and support the concept that, irrespective of HPV infection, neuroendocrine differentiation portends a poor prognosis. 相似文献

Importance
Appendicitis is a common, potentially serious pediatric disease. An important factor in determining management strategy [whether/when to perform appendectomy, duration of antibiotic therapy/hospitalization, etc.] and predicting outcome is distinguishing whether perforation is present.Objective
The objective was to determine efficacy of commonly assessed pre-operative variables in stratifying perforation risk in children with appendicitis.Design
A retrospective analysis of consecutive cases was performed.Setting
The setting was a large urban hospital pediatric emergency department.Participants
Four hundred forty-eight consecutive cases of CT [computerized tomography]-confirmed pediatric appendicitis during a 6-year period in an urban pediatric ED [emergency department]: 162 with perforation and 286 non-perforated.Main outcome(s) and measure(s)
To determine efficacy of clinical and laboratory variables with distinguishing perforation outcome in children with appendicitis.Results
Regression analysis identified 3 independently significant variables associated with perforation outcome – and determined their ideal threshold values: duration of symptoms > 1 day; ED-measured fever [body temperature > 38.0 °C]; CBC WBC absolute neutrophil count > 13,000/mm3. The resulting multivariate ROC [receiver operating characteristic] curve after applying these threshold values gave an AUC [area under curve] of 89% for perforation outcome [p < 0.001]. Risk for perforation was additive with each additional predictive variable exceeding its threshold value, linearly increasing from 7% with no variable present to 85% when all 3 variables are present.Conclusions
A pre-operative scoring system comprised of 3 commonly assessed clinical/laboratory variables is useful in stratifying perforation risk in children with appendicitis.Physicians can utilize these factors to gauge pre-operative risk for perforation in children with appendicitis, which can potentially aid in planning subsequent management strategy.Level of evidence
