Patient-reported Outcomes After External Beam Radiotherapy With Low Dose Rate Brachytherapy Boost vs Radical Prostatectomy for Localized Prostate Cancer: Five-year Results From a Prospective Comparative Effectiveness Study.

BackgroundParenteral nutrition (PN) is used as nutritional support in patients that are malnourished, critically ill, and/or have a nonfunctional gut. Patients receiving PN are at increased risk for both infectious and noninfectious catheter complications often leading to increased morbidity and mortality. Risk factors for catheter complications in patients receiving PN are often variable and poorly understood.MethodsWe conducted retrospective study among cancer patients who received PN between January 1, 2013 and December 31, 2015 at the University of Texas MD Anderson Cancer Center. Rate and prevalence of central line associated blood stream infection (CLABSI) and noninfectious catheter complications were assessed. Additionally, prevalence and time-to-infection of causative pathogens were evaluated. Multivariate logistic regression analyses were conducted in a sample of the PN population to identify risk factors for both infectious and noninfectious catheter complications.ResultsWe identified 46 CLABSI cases in 38 patients of the 1,762 patients receiving PN (1.73 episodes of CLABSI per 1000 PN days). Gram-positives (37.84%) and yeast (29.73%) were the most common pathogens, with catheter-related Candidemias occurring earlier than gram-positive or gram-negative CLABSI. Noninfectious catheter complications occurred in 56 patients (38.6%). Multivariate analysis identified age, GVHD, and history of occlusion in the same catheter, as well as intestinal failure and long-term PN use as significant risk factors for CLABSI and noninfectious catheter complications, respectively.ConclusionPatients receiving PN are at higher risk for both infectious and noninfectious catheter complications. Compared with national averages of CLABSI, the prevalence of catheter-related Candidemias in the PN cancer patient population was increased. This study highlights the need for development of more effective targeted preventative interventions.DisclosuresJ.

Waun Ki Hong and John Mendelsohn were vastly different characters, with different backgrounds and strengths. Yet once together at The University of Texas MD Anderson Cancer Center in Houston, the combination of these 2 great men had an enormous impact on reinvigorating the institution and generations of physicians, scientists, and patients.

Anaplastic thyroid carcinoma (ATC) is an aggressive disease that requires rapid diagnosis and multimodality treatment. Recent advances in targeted therapeutics have provided ATC patients with previously unavailable treatment options, which may improve clinical outcomes in the coming years. Continued development of high-throughput next-generation sequencing provides clinicians with an unparalleled ability to characterize the genomic background of tumors in order to guide treatment selection and clinical trial enrollment. Twenty-three patients with ATC treated at the University of Texas MD Anderson Cancer Center between August 2015 and April 2016 were evaluated. All patients underwent next-generation sequencing using an institutional tissue-based DNA platform (50 genes) and a commercially available cell-free circulating DNA (cfDNA) platform (70 genes). Sequencing data were successfully obtained for both platforms on all patients. The most commonly mutated genes noted on both platforms were TP53 (15/23; 65%) and BRAF (11/23; 48%). Concordance between the tumor and cfDNA data was high for BRAF, PIK3CA, NRAS, and PTEN and moderate for TP53. Concordance was highest in patients who underwent dual-platform sequencing prior to initiation of definitive treatment, and lowest in patients who underwent cfDNA analysis following treatment. Nineteen patients had treatment at the University of Texas MD Anderson Cancer Center following cfDNA sequencing. One patient was observed, and three patients opted for hospice. At the time of last contact, 15/23 (65%) patients were alive. Next-generation sequencing platforms offer clinicians an opportunity to identify targetable oncogenic events in ATC. To the authors' knowledge, this is the largest sequential cohort of ATC patients who have undergone targeted genomic profiling. Based on these data, utilization of both tumor-based and cfDNA analysis in the context of clinical-trial development and application is recommended. Integration of these or similar platforms in clinical-trial implementation may have the potential to transform clinical outcomes for patients with ATC.

At the present time, we do not have access to predictors of response to hypomethylating agents. MicroRNA (miRNAs) are noncoding RNAs of 19–25 nucleotides in length that regulate gene expression by inducing translational inhibition and cleavage of their target mRNAs through base pairing to partially or fully complementary sites. Altered miRNA expression has been documented in multiples types of leukemia [1]. Acute myeloid leukemia (AML) is a cytogenetically and molecularly heterogeneous disorder characterized by differentiation arrest and malignant proliferation of clonal myeloid precursors. Specific miRNA signatures are associated with cytogenetics and prognosis in AML [2]. Recently it has been reported that pretreatment expression levels of miR-29b are associated with clinical response in patients with AML treated with a 10-day schedule of decitabine [3]. miR-29b is involved in the regulation of DNA methylation and is down regulated in AML [3, 4]. The hypothesis is that patients with higher miR-29b levels would have lower levels of DNA methyltransferase, less hypomethylation, and potentially increased sensitivity to decitabine [3]. This hypothesis is in line with previous observations associating lower levels of p15 methylation with response to decitabine based therapy [5].The findings of Blum et al. [3] are therefore very significant as detection of miR-29b, if validated, could be used to select hypomethylating-based therapy in AML. To follow on these observations, we have analyzed miR-29b and miR-101 expression levels in a cohort of patients with AML or high-risk myelodysplastic syndrome treated in a phase I/II study of the combination of 5-azacitidine (5-AZA), valproic acid, and ATRA [6]. We analyzed 45 patients, 28 of which had not received prior therapy. The characteristics of these patients have been previously reported [6]. Eight (29%) patients achieved a complete remission and 1 (4%) partial remission. Total cellular RNA (extracted from unselected peripheral blood mononuclear cells collected before the first cycle of treatment) was used for reverse transcription reactions using TaqMan miRNA reverse transcription kit (Applied Biosystems). As a control, we also analyzed levels of miR-101. For real-time PCR, miR-29b and miR-101 TaqMan - miRNA assays were purchased from Applied Biosystems and analyzed with TaqMan Universal PCR Master Mix (Applied Biosystems) using an Applied Biosystems Prism 7500 Sequencing detection system. The U6 small nuclear RNA was used as internal control. Expression levels of miR-29b and miR-101 from 45 patients were compared to 6 healthy donors. Expression levels of miR-29b were significantly down-regulated in patients compared to normal controls (P= 0.001) (Fig. 1A). There were no difference in terms of miR-101 expression between patients and health donors. We then compared the miR-29b and miR-101 expression levels between patients who responded to the combination therapy versus nonresponders: no differences were observed for both miR-29b and miR-101 expression (P= 0.56) (Fig.1B). Difference in baseline miR-29b expression levels. (A) Difference in baseline miR-29b expression levels between AML patients and healthy controls. (B) Difference in baseline miR-29b expression levels between responders and nonresponders. Exact P values are shown over the columns; unpaired, two-tailed t test were performed for statistical analysis. Our results fail to detect a relationship between miR-29b levels and response to 5-AZA based therapy. This difference could be explained by the relative small sample size, the source of RNA (peripheral blood versus bone marrow) and potentially the fact that miR-29b may predict for response to decitabine but not to 5-AZA in combination. In regards to the source of RNA, it should be noted that Blum et al. used unsorted bone marrow specimens whereas we used peripheral blood. The median blast percent in the blood of our patients was 6% (range 0–86%) whereas it was 35% (range 8–93%) in the bone marrow. In our experience, it is unlikely that the differences in blast percentage would explain the potential differences in gene expression levels. Despite these limitations, these results indicate that larger studies need to be performed to confirm the role of miRNAs in response to hypomethylating agent based therapy.
