SummaryTo examine the effectiveness of an initial management strategy of watchful waiting for follicular lymphoma (FL) in clinical practice, we compared outcomes for patients diagnosed 2004–2007 in the United States initially managed with watchful waiting with outcomes following initial rituximab monotherapy and chemoimmunotherapy. In total, 1754 stage II–IV patients in the National LymphoCare Study underwent watchful waiting (n = 386), rituximab monotherapy (n = 296) or rituximab plus chemotherapy (n = 1072) as initial management strategy. Female patients and those who received treatment in the Northeast or in an academic setting more commonly underwent watchful waiting versus initial chemoimmunotherapy; whereas patients with grade 3 histology, anaemia, elevated lactate dehydrogenase, extranodal involvement, B symptoms or performance status ≥1 more commonly received chemoimmunotherapy. Although time to new treatment and progression‐free survival following first‐ and second‐line therapy were improved with chemoimmunotherapy, and time to chemotherapy was improved with rituximab monotherapy, there were no differences in overall survival between watchful waiting and chemoimmunotherapy or rituximab monotherapy. With 8‐year overall survival estimates of 74%, initial management with watchful waiting in the context of sequential therapy remains a viable option for FL patients in the modern era.

ObjectiveInfantile spasms are seizures associated with a severe epileptic encephalopathy presenting in the first 2 years of life, and optimal treatment continues to be debated. This study evaluates early and sustained response to initial treatments and addresses both clinical remission and electrographic resolution of hypsarrhythmia. Secondarily, it assesses whether response to treatment differs by etiology or developmental status.MethodsThe National Infantile Spasms Consortium established a multicenter, prospective database enrolling infants with new diagnosis of infantile spasms. Children were considered responders if there was clinical remission and resolution of hypsarrhythmia that was sustained at 3 months after first treatment initiation. Standard treatments of adrenocorticotropic hormone (ACTH), oral corticosteroids, and vigabatrin were considered individually, and all other nonstandard therapies were analyzed collectively. Developmental status and etiology were assessed. We compared response rates by treatment group using chi‐square tests and multivariate logistic regression models.ResultsTwo hundred thirty infants were enrolled from 22 centers. Overall, 46% of children receiving standard therapy responded, compared to only 9% who responded to nonstandard therapy (p < 0.001). Fifty‐five percent of infants receiving ACTH as initial treatment responded, compared to 39% for oral corticosteroids, 36% for vigabatrin, and 9% for other (p < 0.001). Neither etiology nor development significantly modified the response pattern by treatment group.InterpretationResponse rate varies by treatment choice. Standard therapies should be considered as initial treatment for infantile spasms, including those with impaired development or known structural or genetic/metabolic etiology. ACTH appeared to be more effective than other standard therapies. ANN NEUROL 2016;79:475–484

ObjectivesTo investigate the utility and safety of the GuideLiner “mother‐and‐child” catheter system during transradial and transfemoral percutaneous coronary intervention (PCI).BackgroundIn patients with complex coronary anatomy, stent delivery can be challenging and result in procedural failure and complications. The GuideLiner is a coaxial guide extension system designed to enable deep vessel engagement and facilitate device delivery. The purpose of this study was to evaluate procedural success and safety in a series of GuideLiner‐facilitated PCI.MethodsSingle center retrospective study of PCI utilizing the GuideLiner catheter between February 2010 and October 2014. Patients who underwent PCI without GuideLiner use during the same time period were used as controls for comparison.ResultsA total of 363 cases of GuideLiner‐facilitated PCI were identified from 6,088 unique PCI procedures performed during this same time period. Patients in the GuideLiner group were older (mean age 71.5 vs. 67.8, P < 0.001) and had more multivessel disease (72% vs. 63%, P = 0.001) compared with controls. Type C lesions were present in 78% of GuideLiner cases. Procedural success resulting in successful device delivery with the GuideLiner catheter was 80.2%. Stent deformation associated with GuideLiner use occurred in 2.2% (8/363), with the incidence of this complication decreasing over device iterations. Coronary dissection attributed to GuideLiner occurred in 3.3% (12/363) and became less frequent over the study period.ConclusionsIn this consecutive series of GuideLiner supported PCI, the guide extension system enabled procedural success in the majority. A decline in device‐associated complications over time may be attributed to operator learning curve, patient selection, and improvement in catheter design. © 2015 Wiley Periodicals, Inc.

ABSTRACTBackgroundThe objective of this study was to investigate cardiovascular disease risk factor (cvRF) profiles and compare their trends over 17 years in patients with and without acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI).HypothesisTime trends of cvRF are different between ACS and non‐ACS patients.MethodsThis study was a time‐trend analysis from 1994 to 2010 within the Mayo Clinic PCI registry. Outcome measures were incidence and prevalence of cvRF, including the Framingham Risk Score (FRS), at the time of admission for PCI.ResultsAge of non‐ACS patients was higher than that of ACS patients, and age distribution slightly shifted toward older age in both groups (P for trend <0.001). There was no difference in FRS between the 2 groups; however, 10‐year cardiovascular disease risk (%) remained higher in non‐ACS than in ACS patients, decreasing over time. Diastolic blood pressure and high‐density lipoprotein cholesterol were higher in non‐ACS patients, but total cholesterol and low‐density lipoprotein cholesterol were higher in ACS patients, with an improving trend over time. Prevalence of diabetes mellitus, hypertension, and history of hypercholesterolemia were higher in non‐ACS patients, increasing over time. Smoking did not change over time. Use of most medications increased over time in both groups.ConclusionsMost cvRFs and their time trends exhibited statistically significant differences between ACS and non‐ACS patients, except systolic blood pressure, body mass index, and history of myocardial infarction. A new risk‐factor profile assessment may be needed for stratification of PCI patients according to ACS and non‐ACS status. Clinical and public‐health interventions should consider different approaches to ACS and non‐ACS patients.

AbstractBackgroundFactors predicting locoregional relapse after surgery for oropharyngeal squamous cell carcinoma (SCC) were identified in the pre‐human papillomavirus (HPV) era. We examined whether traditional indications for adjuvant radiotherapy (RT) or adjuvant chemoradiotherapy (CRT) still correlate with locoregional relapse in HPV‐positive patients after transoral robotic surgery (TORS).MethodsRetrospective review of oropharyngeal SCC cases identified patients with HPV‐positive tumors who did not receive adjuvant therapy after TORS despite intermediate or high‐risk features.ResultsMedian follow‐up was 26.7 months (range, 4.9–73.1 months). Five of 25 eligible patients (20%) relapsed at a median 4.8 months (range, 3.2–7.8 months). Two of 18 (11%) intermediate and 3 of 7 (43%) high‐risk patients relapsed. Kaplan–Meier 2‐year locoregional relapse‐free survival estimates for intermediate and high‐risk patients were 88% and 57% (p = .078), respectively.ConclusionTraditional indications for adjuvant RT or CRT were associated with high risk of locoregional relapse in HPV‐positive patients treated with TORS alone. © 2015 Wiley Periodicals, Inc.
