Objective To investigate the incidence and prognosis of multiple primary malignant neoplasms of urologic and male genital system. Methods 22 cases of multiple primary neoplasms patients treated from Jan 1980 to Jun 2000 were studied retrospectively. Results The total incidence rate of the multiple malignant neoplasms was 3.2%.In the 7 patients with synchronous occurrence of multiple pramary malignant neoplasms,the survival time was 6 to 40 months,with a mean of 15;In the other 15 patients,3 died after 7 months to 5 years,12 have survived 8 months to 15 years after the second carcinoma being treated. Conclusions Multiple primary malignant neoplasms of urologic and male genital system is more frequently seen ronadays.Early diagnosis and adequate treatment of the second primary carcinoma is the only means to achieve a long survival.So the patient should be closely followed up after the first carcinoma being treated.

BACKGROUND: Breast cancer is the most common type of cancer in females. Aberrant expression of microRNA-21 (miR-21) has previously been reported in breast cancer tissue. The aim of this study was to investigate expression levels of serum miR-21 in breast cancer patients and evaluate its prognostic value in Chinese females. METHODS: Real-time quantitative (RQ)-PCR was used to analyze miR-21 expression in archived serum, tumor tissue, and adjacent normal tissue from 549 participants (326 with breast cancer, 223 without breast cancer). We also analyzed associations between serum miR-21 expression and breast cancer subtypes and patient prognosis. Recurrence and survival were analyzed by using the multivariate Cox proportional hazards model. RESULTS: Expression of miR-21 was significantly higher in breast cancer tissues compared with normal adjacent breast tissues (P<0.001). The 2(-DeltaDeltaCt) values for serum miR-21 in breast cancer patients versus healthy controls were 9.12+/-3.43 and 2.96+/-0.73, respectively. Multivariate Cox proportional hazards model suggested that serum miR-21 expression was an independent poor prognostic factor for both recurrence (hazard ratio [HR]= 2.942; 95% confidence interval [CI]=1.420-8.325; P=0.008) and disease-free survival (HR=2.732; 95% CI=1.038-7.273, P=0.003) in breast cancer. CONCLUSIONS: Increased serum miR-21 expression level was correlated with poor prognosis of breast cancer patients, indicating that serum miR-21 may be a novel prognostic marker for recurrence and survival of breast cancer patients before resection.
