Increasingly, biomarkers that can be readily assayed from blood or other body fluids will be critical to risk stratification and effective application of secondary prevention strategies, just as they have played an increasingly prominent role in www.selleckchem.com/products/gw4869.html risk stratification of acute coronary syndrome patients.”
“Purpose
This study compared the clinical outcomes of T1-2N1 breast cancer patients with and without postmastectomy radiotherapy (PMRT). Risk factors for loco-regional recurrence (LRR) were identified
in order to define a subgroup of patients who might benefit from PMRT.
Materials and Methods
Of 110 T1-2N1 breast cancer patients who underwent mastectomy from January 1994 through December 2009, 32 patients underwent PMRT and 78 patients
did not. Treatment outcomes and risk factors for LRR were analyzed.
Results
The 5- and 10-year LRR rates were both 6.2% in the PMRT group, and 10.4% and 14.6% in the no-PMRT group (p=0.336). In addition, no significant differences in distant metastasis-free survival Bromosporine chemical structure (DMFS) or overall survival (OS) were observed between patients receiving and not receiving PMRT. In multivariate analysis, factors associated with higher LRR rates included grade 3 disease, extracapsular extension (ECE), and triple negative subtype. Patients who had one or more risk factors for LRR were defined as a high-risk patient group. In the high-risk group, both 5- and 10-year LRR rates for patients who Quisinostat underwent PMRT was 18.2%, and LRR rates of 21.4% at five years and 36.6% at 10 years were observed for patients who did not undergo PMRT (p=0.069).
Conclusion
PMRT in T1-2N1 breast cancer patients should be considered according to several prognostic factors in addition to T and N stage. Findings of our study indicated that PMRT did not improve LRR, DMFS, or OS in
T1-2N1 breast cancer patients. However, in a subgroup of patients with grade 3 disease, ECE, or triple negative subtype, PMRT might be beneficial.”
“Despite major achievements in medicine, preterm birth (PTB) remains a leading cause of infant morbidity and mortality, worldwide. Research efforts have been devoted towards a better understanding of the multifactorial aetiology of PTB and its sub-types, with the purpose of prevention and control. The availability of valid and reliable gestational age data is a prerequisite for PTB classification. Pregnancies conceived through assisted reproduction treatments provide an opportunity for the exact determination of gestational age using date of delivery and dates of fertilization or implantation. The purpose of this review article is to evaluate the current evidence for or against the various methods that can be applied to measure gestational age, namely the first day of the last menstrual period, ultrasound before 20 weeks of gestation and post-natal assessments, and to propose the use of assisted reproduction treatments populations for further validation of these methods.
