ABSTRACT
In novel agent era, the impact of immunoparesis at diagnosis on outcomes in symptomatic multiple myeloma (MM) remains unclear. We reviewed medical records of 147 MM patients at Beijing Chao Yang hospital. Most patients exhibited immunoparesis at diagnosis (84%). After a median follow-up of 27 months (range 1-78 months), in the group with immunoparesis at diagnosis, there was a very significantly shorter progression-free survival (PFS) than in the group without immunoparesis (estimated PFS of not reached vs 25 months, P = 0.001). Patients with suppressed Immunoglobulins (Igs) had the tendency to have a shorter OS than patients without suppression (estimated OS of not reached vs 38 months, P = 0.06). In multivariate analysis, the negative impact of immunoparesis on PFS was confirmed. In addition, achievement of both at least VGPR and at least CR was significantly higher in patients with preserved uninvolved Igs than in those with suppression of at least one uninvolved Ig. However, the negative impact of immunoparesis on response was not confirmed in a multivariate analysis. These results suggest immunoparesis in patients with symptomatic MM at diagnosis is an independent poor prognostic factor for upfront bortezomib-containing regimen.

Background The role of a tailored surgical approach for hypertrophic cardiomyopathy (HCM) on regional ventricular remodelling remains unknown. The aims of this study were to evaluate the pattern, extent and functional impact of regional ventricular remodelling after a tailored surgical approach. Methods From 2005 to 2008, 44 patients with obstructive HCM underwent tailored surgical intervention. Of those, 14 were ineligible for cardiac magnetic resonance (CMR) studies. From the remainder, 14 unselected patients (42±12 years) underwent pre- and post-operative CMR studies at a median 12 months post-operatively (range 4-37 months). Regional changes in left ventricular (LV) thickness as well as global LV function following surgery were assessed using CMR Tools (London, UK). Results Pre-operative mean echocardiographic septal thickness was 21±4 mm and mean LV outflow gradient was 69±32 mmHg. Following surgery, there was a significant degree of regional regression of LV thickness in all segments of the LV, ranging from 16% in the antero-lateral midventricular segment to 41% in the anterior basal segment. Wall thickening was significantly increased in basal segments but showed no significant change in the midventricular or apical segments. Globally, mean indexed LV mass decreased significantly after surgery (120±29g/m2 versus 154±36g/m2; p<0.001). There was a trend for increased indexed LV end-diastolic volume (70±13 mL versus 65±11 mL; p=0.16) with a normalization of LV ejection fraction (68±7% versus 75±9%; p<0.01). Conclusion Following a tailored surgical relief of outflow obstruction for HCM, there is a marked regional reverse LV remodelling. These changes could have a significant impact on overall ventricular dynamics and function.
