Use of hyperthermia versus normothermia during intraperitoneal chemoperfusion with oxaliplatin for colorectal peritoneal carcinomatosis: A propensity score matched analysis

BackgroundHyperthermic intraperitoneal chemotherapy (HIPEC) with oxaliplatin (OX) is increasingly used in the treatment of colorectal peritoneal carcinomatosis (PC). However, the additional benefit of hyperthermia remains clinically unproven, while it may aggravate postoperative morbidity. Here, we report the correlation of perfusion temperature with postoperative morbidity during clinical HIPEC with OX.Patients and methodsPatients who underwent hyperthermic (41 °C, HT) or normothermic (37 °C, NT) chemoperfusion with OX for colorectal PC were identified from a prospectively kept database of HIPEC cases and matched for baseline characteristics using propensity score (PS) analysis. The groups were compared to assess the impact of perfusion temperature on morbidity. Morbidity was graded using the Clavien-Dindo (CD) classification and the Comprehensive Complication Index (CCI).ResultsOut of 612 patients, 146 patients met the inclusion criteria and from these patients, 45 HT patients were matched with 45 NT patients. Baseline variables were comparable between the PS matched groups. Overall mortality was 0.7% and major morbidity (CD ≥ 3) occurred in 35,6% of patients. There were no significant differences between the HT and NT cohorts in mortality, major morbidity (RR 1.33, 95% CI 0.71 to 2.49, p = 0.36), anastomotic leakage (13.8% versus 11.1%, p = 1.0), hemorrhagic complications, or systemic toxicity. A trend of increased wound infections was observed in the hyperthermia group (13.3% versus 4.4%, P = 0.27).ConclusionsCompared to NT, the use of HT during HIPEC with OX does not aggravate postoperative mortality or morbidity in a high-volume center.

The prognostic and predictive role of 21-gene recurrence scores in hormone receptor-positive early-stage breast cancer

Over the past two decades, gene expression profiling of breast cancer has emerged as an important tool in early-stage breast cancer management. The approach provides important information on underlying biological mechanisms, breast cancer classification, future risk potential of developing recurrent metastatic disease, and provides beneficial clues for adjuvant chemotherapy in hormone receptor (HR) positive breast cancer. Of the commercially available genomic tests for breast cancer, the prognostic and predictive value of 21-gene recurrence score tests have been validated using both retrospective data and prospective clinical trials. In this paper, we reviewed the current evidence on 21-gene expression profiles for HR-positive HER2-negative early-stage breast cancer management. We show that current evidence supports endocrine therapy alone as an appropriate adjuvant systemic therapy for approximately 70% of women with HR-positive, HER2-negative, node-negative breast cancer. Evolving evidence also suggests that 21-gene recurrence scores have predictive values for node-positive breast cancer and that chemotherapy can be avoided in more than half of women with nodes 1 to 3 positive HR-positive breast cancer. Furthermore, retrospective data also supports the predictive role of 21-gene recurrence scores for adjuvant radiation therapy. A prospective trial in this area is ongoing.

Prognostic Utility of the IPS 3 Score for Predicting Outcomes in Advanced Hodgkin Lymphoma

Background

The International Prognostic Scoring System (IPSS) consisting of 7 parameters (IPS7) has been the standard prognostic model used in advanced Hodgkin lymphoma (aHL). However, recent studies have questioned its discriminatory power. For retrospective analyses, its utility might be limited by missing parameters. A recent study has shown that the IPSS consisting of only 3 high-risk features (IPS3; stage IV, age 45 years or older, and hemoglobin <105 g/L) is a simple predictor of survival in aHL. However, there are limited data validating the IPS3.

Low-dose l-isoproterenol versus salbutamol in hospitalized pediatric patients with severe acute exacerbation of asthma: A double-blind,randomized controlled trial

BackgroundAlthough the guidelines in most countries do not recommend continuous inhalation of l-isoproterenol to treat pediatric patients with acute severe exacerbation of asthma, lower dose of l-isoproterenol has been widely used in Japan. To determine whether the efficacy of low-dose l-isoproterenol was superior to that of salbutamol, we conducted a double-blind, randomized controlled trial.MethodsHospitalized patients aged 1–17 years were eligible if they had severe asthma exacerbation defined by the modified pulmonary index score (MPIS). Patients were randomly assigned (1:1) to receive inhalation of l-isoproterenol (10 μg/kg/h) or salbutamol (500 μg/kg/h) for 12 hours via a large-volume nebulizer with oxygen. The primary outcome was the change in MPIS from baseline to 3 hours after starting inhalation. Trial registration number UMIN000001991.ResultsFrom December 2009 to October 2013, 83 patients (42 in the l-isoproterenol group and 41 in the salbutamol group) were enrolled into the study. Of these, one patient in the l-isoproterenol group did not receive the study drug and was excluded from the analysis. Compared with salbutamol, l-isoproterenol reduced MPIS more rapidly. Mean (SD) changes in MPIS at 3 hours were −2.9 (2.5) in the l-isoproterenol group and −0.9 (2.3) in the salbutamol group (difference −2.0, 95% confidence interval −3.1 to −0.9; P < 0.001). Adverse events occurred in 1 (2%) and 11 (27%) patients in the l-isoproterenol and salbutamol groups, respectively (P = 0.003). Hypokalemia and tachycardia occurred only in the salbutamol group.ConclusionsLow-dose l-isoproterenol has a more rapid effect with fewer adverse events than salbutamol.     

Bypass Surgery or Stenting for Left Main Coronary Artery Disease in Patients With Diabetes

Background

The randomized EXCEL (Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial reported a similar rate of the 3-year composite primary endpoint of death, myocardial infarction (MI), or stroke in patients with left main coronary artery disease (LMCAD) and site-assessed low or intermediate SYNTAX scores treated with percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). Whether these results are consistent in high-risk patients with diabetes, who have fared relatively better with CABG in most prior trials, is unknown.

Synthetic MRI is not yet ready for morphologic and functional assessment of patellar cartilage at 1.5 Tesla

PurposeThe purpose of this study was to compare morphologic assessment and relaxometry of patellar hyaline cartilage between conventional sequences (fast spin-echo [FSE] T2-weighted fat-saturated and T2-mapping) and synthetic T2 short-TI inversion recovery (STIR) and T2 maps at 1.5 T magnetic resonance imaging (MRI).MethodThe MRI examinations of the knee obtained at 1.5 T in 49 consecutive patients were retrospectively studied. There were 21 men and 28 women with a mean age of 45 ± 17.7 (SD) years (range: 18–88 years). Conventional and synthetic acquisitions were performed, including T2-weighted fat-saturated and T2-mapping sequences. Two radiologists independently compared patellar cartilage T2-relaxation time on conventional T2-mapping and synthetic T2-mapping images. A third radiologist evaluated the patellar cartilage morphology on conventional and synthetic T2-weighted images. The presence of artifacts was also assessed. Interobserver agreement for quantitative variables was assessed using intraclass correlation coefficient (ICC).ResultsIn vitro, conventional and synthetic T2 maps yielded similar mean T2 values 58.5 ± 2.3 (SD) ms and 58.8 ± 2.6 (SD) ms, respectively (P = 0.414) and 6% lower than the expected experimental values (P = 0.038). Synthetic images allowed for a 15% reduction in examination time compared to conventional images. On conventional sequences, patellar chondropathy was identified in 35 patients (35/49; 71%) with a mean chondropathy grade of 4.8 ± 4.8 (SD). On synthetic images, 28 patients (28/49; 57%) were diagnosed with patellar chondropathy, with a significant 14% difference (P = 0.009) and lower chondropathy scores (3.7 ± 4.9 [SD]) compared to conventional images. Motion artifacts were more frequently observed on synthetic images (18%) than on conventional ones (6%). The interobserver agreement was excellent for both conventional and synthetic T2 maps (ICC > 0.83). Mean cartilage T2 values were significantly greater on synthetic images (36.2 ± 3.8 [SD] ms; range: 29-46 ms) relative to conventional T2 maps (31.8 ± 4.1 [SD] ms; range: 26-49 ms) (P < 0.0001).ConclusionDespite a decrease in examination duration, synthetic images convey lower diagnostic performance for chondropathy, greater prevalence of motion artifacts, and an overestimation of T2 values compared to conventional MRI sequences.
