Results: There was no evidence of association between the PHB 1630 C>T and MTHFR 677 C>T polymorphisms with either disease for BRCA1 or BRCA2 mutation carriers when breast and ovarian cancer associations were evaluated separately. Analysis that evaluated associations for breast and ovarian cancer simultaneously showed some evidence that BRCA1 mutation carriers who had the rare homozygote genotype (TT) of the PHB 1630 C>T polymorphism were at increased risk of both breast and ovarian cancer (HR 1.50, 95%CI 1.10–2.04 and HR 2.16, 95%CI 1.24–3.76, respectively). However, there was no evidence of association under a multiplicative model for the effect of each minor allele. Conclusion: The PHB 1630TT genotype may modify breast and ovarian cancer risks in BRCA1 mutation carriers. This association need to be evaluated in larger series of BRCA1 mutation carriers.]]> Wed 07 Jul 2021 11:42:58 AEST ]]> Continuous versus intermittent extended adjuvant letrozole for breast cancer: final results of randomized phase III SOLE (Study of Letrozole Extension) and SOLE Estrogen Substudy https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:53186 Wed 07 Feb 2024 15:28:37 AEDT ]]> Patterns and risk factors for locoregional failures after mastectomy for breast cancer: an international breast cancer study group report https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:21434 15% was seen in patients aged <40 years (16.1%), with ≥4 positive nodes (16.5%) or 0–7 uninvolved nodes (15.1%); for supraclavicular failures >10%: ≥4 positive nodes (10.2%); for axillary failures of >5%: aged <40 years (5.1%), unknown primary tumor size (5.2%), 0–7 uninvolved nodes (5.2%). In patients with 1–3 positive nodes, 10-year cumulative incidence for chest wall recurrence of >15% were age <40, peritumoral vessel invasion or 0–7 uninvolved nodes. Age, number of positive nodes and number of uninvolved nodes were significant parameters for each locoregional relapse site. Conclusion: PMRT to the chest wall and supraclavicular fossa is supported in patients with ≥4 positive nodes. With 1–3 positive nodes, chest wall PMRT may be considered in patients aged <40 years, with 0–7 uninvolved nodes or with vascular invasion. The findings do not support PMRT to the dissected axilla.]]> Sat 24 Mar 2018 08:05:46 AEDT ]]>
