ABSTRACT
Objective To investigate the role of the mass screening by comparing the pathological features of prostate cancer between mass screening patients and clinical patients.Methods 107 cases of prostate cancer(including 51 patients from clinical diagnosis and 56 patients from mass screening) and 7 cases of prostate intraepithelial neoplasia(PIN,from mass screening) were analyzed using the Gleason’s grade system.Results ① Gleason’s grade of prostate cancer in mass screening group was lower than that in clinical diagnosis group(?2 =48.22,P
ABSTRACT
AIM: To investigate expression of CD44s in lung cancer and it's clinical significance. METHODS: A total of 117 primary lung cancer from patients were examined for CD44s expression by immunohistochemical staining. RESULTS: CD44s mostly expressed in non-small cell lung cancer (NSCLC) but not in small ecll lung cancer (SCLC), and squamous cell carcinoma(SCC) showed much stronger expression of CD44s than adenocarcinoma(ADC)(P
