Abstract: As diagnostic and therapeutic modalities for Hodgkin's Lymphoma (HL) continue to improve, patient‐related factors affecting survival become more difficult to identify. Very little is known about the relationship between the primary site of lymph node (LN) involvement and survival of HL patients. We retrospectively analyzed the United States Surveillance, Epidemiology and End Results (SEER) database for 12,658 HL patients reported between 1973 and 2010 using survival analysis and time‐interval multiple logistic regression (MLR) to disclose that relationship. The effect of all primary LN sites on the survival of HL patients was supported. The intra‐abdominal (IAB) primary LN site was significantly associated with the worst survival. The pelvic (P) LN sites were significantly and independently associated with nearly 2 times and 2.5 times the probability of having 1‐year overall mortality (OM) and 1‐year cancer‐specific mortality (CSM), respectively. Head, face and neck (HFN) primary LN sites were significant and independent predictors of better overall and HL‐specific survival. A worse survival with the intra‐abdominal primary LN site was probably related to their association with higher age, or advanced stages of HL. The biological basis behind the aggressiveness of intra‐abdominal and pelvic LN sites is yet to be investigated. [ABSTRACT FROM AUTHOR]

Background: Patients undergoing non-cardiac surgery are at risk for peri-operative major cardiac events (PMCEs). The most common risk assessment tool is Revised Cardiac Risk Index (RCRI). N-terminal pro-brain natriuretic peptide (NT-proBNP) measured peri-operatively has prognostic information but the implication is uncertain. This study aimed to determine the accuracy of combining NT-proBNP and RCRI in predicting the PMCE in major non-cardiac surgery.Methods: We performed a prospective cohort study to include non-cardiac surgical patients with moderate or high risk. PMCE included myocardial infarction, pulmonary edema, severe cardiac arrhythmias, and cardiac death occurring within 30 days post-operatively. Logistic regression models and the receiver operating characteristic (ROC) curves were used to determine the discriminative ability of NT-proBNP alone or incorporation with RCRI or its components in predicting PMCE.Results: A total of 366 patients was included in the study with 48 PMCEs. When predicting PMCE, the area under the ROC curve (AUC) (95%-CI) of NT-proBNP alone and NT-proBNP incorporated with RCRI were 0.875 (0.819-0.932) and 0.882 (0.827-0.937), respectively. When incorporating NT-proBNP with the RCRI's components, the best four chosen models had the AUCs between 0.879 and 0.891. All these AUCs were not significantly different with the AUC of NT-proBNP alone.Conclusions: Higher preoperative NT-proBNP level leads to the increased risk of PMCE in patients undergoing non-cardiac surgery. Compared to NT-proBNP alone, the combination of NT-proBNP with the RCRI and other factors does not improve the accuracy in predicting PMCE. Future large studies are required to build a more accurate risk score. [ABSTRACT FROM AUTHOR]
