HighlightsA large population based analysis to evaluate pathologic response according to time of surgery.LARC patients were treated with modern techniques of radiotherapy and surgery.The rate of pCR increased according to time interval from 12.6% to 31.1%.The pCR increasing was 1.5% (about 0.2%/die) per each week of waiting.Lengthening the interval (>13 weeks) significantly improved the pathological response.
AimsIntermittent levosimendan administration has been suggested to improve survival in patients with advanced heart failure (AdHF). Quality of life is a key issue for AdHF patients and is negatively affected by frequent hospitalizations.Methods and resultsCENTRAL, Google Scholar, MEDLINE/PubMed, Scopus, and the Cochrane Central Register of clinical trials (updated 15/1/2017) were searched for randomized controlled trials investigating the effect of intermittent levosimendan administration in patients with AdHF. The primary outcome was the number of patients requiring rehospitalization 3 months after the end of treatment. A total of 319 patients from six trials were included. Overall pooled analysis showed that the use of levosimendan was associated with a significant reduction in the number of rehospitalizations at 3 months: 33/207 (16%) vs. 39/113 (35%), risk ratio 0.40, 95% confidence interval 0.27–0.59, P < 0.001, I
2 = 0%. This result was confirmed by sensitivity analyses.ConclusionsWithin the limitations of this meta‐analysis including also studies in which endpoints were not independently adjudicated and not clearly specified, repetitive or intermittent administration of levosimendan for patients with AdHF was associated with a reduction in the rehospitalization rate at 3 months. Large, high‐quality randomized controlled trials are needed to confirm this finding.
BackgroundBreast adenomyoepithelioma is an unusual tumor characterized by a biphasic proliferation of epithelial and myoepithelial cells. Most breast adenomyoepitheliomas are considered to be benign or to have a low-grade malignant potential, characterized by propensity for local recurrence. Malignant changes arising in this lesion are extremely rare and may involve one or both cellular components.Case reportWe discuss a case of a 60 year-old woman who began to experience pain in her right breast in January 2009. Breast ultrasound and mammography were performed showing a rounded, hypoechoic solid lesion with ill-defined margins in the right inner-inferior quadrant, suspicious of malignancy. Quadrantectomy of the inner-inferior quadrant of the right breast with sampling of ipsilateral axillary lymph nodes was performed. The histological analysis confirmed the diagnosis of adenomyoepithelioma with focal malignant change of the epithelial component, associated with high-grade malignant myoepithelial change. The patient was treated with adjuvant radiotherapy and her right breast received a dose of Gy 50 with a boost of Gy 10 to the tumor bed. At present, the patient shows no sign of tumor recurrence.ConclusionBreast malignant adenomyoepithelioma is a rare tumor which should be considered in the differential diagnosis of other solid breast lesions. Only few cases have been reported in the literature. Diagnosis, optimal therapy and predicting the outcome are problematic issues due to the rarity of this disease which appears to have hematogenous rather than lymphatic spread and usually occurs in primary tumors ≥ 1.6 cm in size.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
