Abstract

ObjectiveTo investigate whether magnetic resonance imaging (MRI) changes the management of patients with screen-detected invasive lobular carcinoma (ILC). MethodsA retrospective, controlled, single-centre analysis of 138 cases of screen-detected ILC was performed. All patients were assessed by a single multidisciplinary team as to whether preoperative MRI altered the initial management decision or reduced re-operation rates. ResultsForty-three percent of patients had preoperative MRI. MRI guided surgical management in 40.7% patients. Primary mastectomy rates were not significantly different between the MRI and non-MRI groups (32% and 30% respectively, p=0.71). The MRI group had a lower secondary surgery rate (6.8% versus 15.2%); however, the results did not reach statistical significance, and there were no unnecessary mastectomies. Conclusions

Phenological and morphological variations of Oryza rufipogon and O. nivara in Sri Lanka and their evolutionary implications

“…Of five Oryza species recognized in Sri Lanka, O. rufipogon and O. nivara are the most common and widely distributed species (Liyanage and Senanayake 2010;Vaughan et al 2008). Importantly, the two wild rice species are parapatric in distribution, with O. rufipogon confined to the wet zone and O. nivara to the dry zone of the country (Liyanage and Senanayake 2010;Sandamal et al 2018;Vaughan et al 2008). This is in marked contrast to the distribution pattern in many other areas in which the two species are largely sympatric despite different habitats (Cai et al 2019;Kuroda et al 2007;Liu et al 2015;Sano et al 1980;Vaughan et al 2008).…”

“…Sri Lanka exhibited diversified and well-understood ecosystems that consist of three main ecological zones (wet, dry, and intermediate) (Fig. 1) (Liyanage and Senanayake 2010;Sandamal et al 2018;Seo et al 2005). Of five Oryza species recognized in Sri Lanka, O. rufipogon and O. nivara are the most common and widely distributed species (Liyanage and Senanayake 2010;Vaughan et al 2008).…”
