Material and methods The MEDLINE, EMBASE and COCHRANE libraries were searched for studies comparing PN, RFA, CRA or MWA and reporting on any-cause or cancer-specific mortality, local recurrence, complications or renal function. Network meta-analyses were performed. Results Forty-seven studies with 24,077 patients were included. Patients receiving RFA, CRA or MWA were older and had more comorbidities compared with PN. All-cause mortality was higher for CRA and RFA compared with PN (incidence rate ratio IRR = 2.58, IRR = 2.58, p < 0.001, respectively). No significant differences in cancer-specific mortality were evident. Local recurrence was higher for CRA, RFA and MWA compared with PN (IRR = 4.13, IRR = 1.79, IRR = 2.52, p < 0.05 respectively). A decline in renal function was less pronounced after RFA versus PN, CRA and MWA (mean difference in GFR MD = 6.49; MD = 5.82; MD = 10.89, p < 0.05 respectively). Conclusion Higher overall survival and local control of PN compared with ablative therapies did not translate into significantly better cancer-specific mortality. Most studies carried a high risk of bias by selecting younger and healthier patients for PN, which may drive superior survival and local control. Physicians should be aware of the lack of high-quality evidence and the potential benefits of ablative techniques for certain patients, including a superior complication profile and renal function preservation. Key Points • Patients selected for ablation of small renal masses are older and have more comorbidities compared with those undergoing partial nephrectomy. • Partial nephrectomy yields lower all-cause mortality, which is probably biased by patient selection and does not translate into prolonged cancer-free survival. • The decline of renal function is smallest after radiofrequency ablation for small renal masses."],["dc.identifier.doi","10.1007/s00330-018-5660-3"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62282"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0938-7994"],["dc.relation.issn","1432-1084"],["dc.title","Partial nephrectomy versus ablative techniques for small renal masses: a systematic review and network meta-analysis"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

Methods: A systematic literature review and meta-analysis was conducted in February 2016.

Random effects meta-analyses were conducted to pool estimates. Results: Literature search identified 3740 studies of which 10 fulfilled the inclusion criteria. Cancer survivors were significantly more likely to utilize bone densitometry (OR=1.226, 95% CI: 1.114 – 1.350, p<0.001) and influenza vaccination (OR=1.565, 95% CI: 1.176 – 2.082, p=0.002) than cancer-free controls.

Conclusions: Cancer survivors were more likely to receive influenza vaccinations and bone densitometry. Future studies should evaluate underlying mechanisms and whether the utilization of preventive services translates into prolonged survival of cancer survivors. Implications for Cancer Survivors: Our meta-analysis demonstrated cancer survivors to be more likely to receive the preventive services such as influenza vaccination and bone densitometry than cancer free controls.

Currently, sufficient data for MPH are lacking. Therefore, it remains unclear if age-dependent alterations in adult hip morphology are physiological and if there are side- and gender-dependent differences. The aim of the study was to analyze MPH according to gender, side and age in a large-scaled cohort by CT scans. Methods: A total of 1576 hip joints from 788 patients (female: 257, male: 531; mean age: 58.3 years (±18.9; 18–92 years)) were analyzed by CT. For all hips, acetabular anteversion (AcetAV); lateral centrum edge angle (LCE); acetabular index (AI); femoral neck version (FNV); centrum-collum-diaphyseal angle (CCD); and anterior alpha angle (AαA) were measured. Results: The mean values in this cohort were: AcetAV 20.5° (±6.9); LCE 40.8° (±8.8); AI 0.3° (±5.3); FNV 11.0° (±9.8); CCD 129.9° (±7.4); and AαA 41.2° (±7.7). There was a detectable side-specific difference for AcetAV (p = 0.001); LCE (p < 0.001); CCD (p < 0.001); and AαA (p < 0.001). All the analyzed parameters showed a significant gender-specific difference, except for AI (p = 0.37).

Sixteen of the 63 MRI-detected hernias (25.4%) were detectable only during Valsalva maneuver, which were smaller compared to hernias at rest (median − 13.5 vs − 33.0 mm, p < 0.001). Diagnostic accuracy for hernia detection was comparable for MRI and endoscopy (sensitivity 74% vs 80%, p = 0.4223; specificity 100% vs 100%, p > 0.99)."],["dc.identifier.doi","10.1007/s00330-019-06284-8"],["dc.identifier.pmid","31187219"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/65367"],["dc.language.iso","en"],["dc.relation.eissn","1432-1084"],["dc.relation.issn","0938-7994"],["dc.title","Hiatal hernias in patients with GERD-like symptoms: evaluation of dynamic real-time MRI vs endoscopy"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
