Serum TPA and CA-125 were determined in 86 individuals (66 with breast cancer representing the different stages and grades of the disease and 20 normal healthy controls). TPA and CA-125 were estimated using the L1A reagents supplied by BYK Sangtec. TPA showed sensitivity rates of 31.8%, 42.4% and 51.5% while CA-125 showed sensitivities of 16.3%, 18.6% and 25.6% at specificity levels of 100%, 95% and 90% respectively. Combined determination of the two markers resulted in some improvement in sensitivity. For follow-up of breast cancer patients after surgery both markers were of value and showed near-identical patterns.

Background: Cancer antigen 15.3 (CA15.3) is a commonly used tumor marker (TM) in metastatic breast cancer (MBC) but may not be raised. We assessed CA15.3, carcinoembryonic antigen (CEA), cancer antigen 125 (CA-125) and cancer antigen 19.9 in 193 MBC patients at diagnosis and follow-up. Materials & methods: This TM panel was measured approximately 3 monthly. Median follow-up was 29.3 months. Results: At diagnosis, the following TMs were raised: CA15.3 63.2%, CEA 37.3%, CA-125 45.0% and cancer antigen 19.9 17.3%. CA15.3 became raised later in 28/71. Raised TMs were less common in HER2+ tumors. CA-125 was frequently raised in triple negative tumors and was associated with pleural metastases. More raised TMs correlated with more sites of metastases and shorter survival. Conclusion: CEA and CA-125 showed benefit over CA15.3 alone in MBC and all three should be considered in MBC.

Background: Breast cancer is the most common cancer diagnosed in women worldwide. So it seems that there's a good chance of recovery if it's detected in its early stages even before the appearances of symptoms. Recent studies have shown that miRNAs play an important role during cancer progression. These transcripts can be tracked in liquid samples to reveal if cancer exists, for earlier treatment. MicroRNA-21 (miR-21) has been shown to be a key regulator of carcinogenesis, and breast tumor is no exception. Objective: The present study was aimed to track the miR-21 expression level in serum of the breast cancer patients in comparison with that of normal counterparts. Methods: Comparative real-time polymerase chain reaction was applied to determine the levels of expression of miR-21 in the serum samples of 57 participants from which, 42 were the patients with breast cancer including pre-surgery patients (n = 30) and post-surgery patients (n = 12), and the others were the healthy controls (n = 15). Results: MiR-21 was significantly over expressed in the serum of breast cancer patients as compared with healthy controls (P = 0.002). A significant decrease was also observed following tumor resection (P < 0.0001). Moreover, it was found that miR-21 overexpression level was significantly associated with tumor grade (P = 0.004). Conclusion: These findings suggest that miR-21 has the potential to be used as a novel breast cancer biomarker for early detection and prognosis, although further experiments are needed.

AbstractEarly reports indicate that metformin, a clinical drug administered to treat type 2 diabetes mellitus (T2DM), was found to be associated with a better prognosis of cancer. The objective of this study was retrospectively analyzed the effect of metformin on the outcomes of Chinese breast cancer patients with T2DM. A total of 3757 primary invasive breast cancer patients who underwent surgery from January 2010 to December 2013 were enrolled. According to the medication treatment, all the patients were divided as non-diabetes group, metformin group and insulin group. The follow-up data for disease-free survival (DFS) and overall survival (OS) were obtained from 3553 patients (median follow up of 85 months) and estimated with the Kaplan–Meier method followed by a log-rank test. Multivariate Cox proportional hazards regression model was applied. The results showed that there was a significant survival difference among non-diabetes group, metformin group and insulin group, 5-year DFS was 85.8%, 96.1%, 73.0%, and 5-year OS was 87.3%, 97.1%, 73.3% respectively (P < 0.05). Prognostic analysis showed metformin was significantly associated with better DFS and OS. Our results suggested that metformin may have a good effect on the survival of invasive breast cancer patients with T2DM.
