Résumé
Objective: To detect the expression of CD133, E-cadherin and WWOX in colorectal cancer, analyze the correlations and pathological significance of the biomarkers
Methods: Two hundred and ten patients with colorectal cancer treated surgically between January 2007 and December 2015 were analyzed retrospectively. All patients had pathologic specimens and integrated clinical data. Pathologic specimens were retrieved for immunohistochemical examination of the expressions of CD133, WWOX and E-cadherin. The clinical data of these patients including gender, age, tumor location, tumor size, tumor differentiation, invasion depth, hepatic metastases, lymphatic metastasis, UICC stage and recurrence of tumor were retrieved to investigate their demographics and clinical characteristics
Results: In 210 specimens of colorectal cancer, the positive expression rate of CD133, E-cadherin and WWOX was 61.9%, 40.5% and 41.9%, respectively. The expression of CD133, E-cadherin and WWOX was significantly correlated with lymphatic metastasis, hepatic metastases and UICC stage [p<0.05]. The expression of CD133 was negatively correlated with WWOX and E-cadherin [p<0.05], and the expression of WWOX was positively correlated with E-cadherin in specimens [p<0.05]
Conclusion: A detection of CD133, E-cadherin and WWOX can facilitate physicians in predicting the progression and prognosis of colorectal cancer
Résumé
This report presented a male patient aged 69 years,who was admitted into our hospital for fever,hemoptysis and chest pain.Chest X-Ray showed shadows on the right lung and pleural thickening.The effect of broad spectrum antibiotic therapy was poor.With the disease progressed,pleural effusion appeared on the right side.Blood culture showed methicillin-resistant staphylococcus aureus.Pleural effusion tests indicated pyothorax,but the effects of closed chest drainage and sensitive antibiotic therapy were poor.After disentangling with open thoracic exploration,the right middle lobe was resected and the right lung lobe pathology showed Wegener granulomatosis.His blood antineutrophil cytoplasmic autoantibodies was negative.The paranasal sinus CT scan and renal function showed no abnormalities.The definitive diagnosis was pulmonary limited Wegener granulomatosis.
