Abstract Evidence regarding the need for surgery for primary intestinal non-Hodgkin lymphoma (PINHL) patients with chemotherapy is limited and controversial. We aimed to investigate the specific impact of surgery on survival of PINHL patients. Data from PINHL patients (aged >18 years) with chemotherapy between 1983 and 2015 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. We concerned about overall survival (OS) and improved cancer-specific survival (CSS). Propensity score matching (PSM) analysis was also used to explore the reliability of the results to further control for confounding factors. Finally, we screened 3537 patients. Multivariate regression analysis showed that patients with surgery and chemotherapy had better OS (hazard ratio [HR], 0·83; 95% confidence interval [CI], 0·75–0·93; P=0·0009) and CSS (HR, 0·87; 95% CI, 0·77–0·99; P=0·0404) compared with the non-operation group after adjusting for confounding factors. After PSM analysis, compared with non-surgery, surgery remained associated with improved OS (HR, 0·77; 95% CI, 0·68–0·87; P<0·0001) and improved CSS (HR, 0·82; 95% CI, 0·72–0·95; P=0·008) adjusted for baseline differences. In the large cohort of PINHL patients with chemotherapy older than 18 years, surgery was associated with significantly improved OS and CSS before and after PSM analysis.

AbstractEvidence regarding the need for surgery for primary intestinal non-Hodgkin lymphoma (PINHL) patients with chemotherapy is limited and controversial. We aimed to investigate the specific impact of surgery on survival of PINHL patients. Data from PINHL patients (aged > 18 years) with chemotherapy between 1983 and 2015 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. We concerned about overall survival (OS) and improved cancer-specific survival (CSS). Propensity score matching (PSM) analysis was also used to explore the reliability of the results to further control for confounding factors. Finally, we screened 3537 patients. Multivariate regression analysis showed that patients with surgery and chemotherapy had better OS (hazard ratio [HR] 0.83; 95% confidence interval [CI] 0.75–0.93; p = 0.0009) and CSS (HR 0.87; 95% CI 0.77–0.99; p = 0.0404) compared with the non-operation group after adjusting for confounding factors. After PSM analysis, compared with non-surgery, surgery remained associated with improved OS (HR 0.77; 95% CI 0.68–0.87; p < 0.0001) and improved CSS (HR 0.82; 95% CI 0.72–0.95; p = 0.008) adjusted for baseline differences. In the large cohort of PINHL patients with chemotherapy older than 18 years, surgery was associated with significantly improved OS and CSS before and after PSM analysis.

PurposeTo identify whether chemoradiotherapy improves survival of stage I nasopharyngeal carcinoma (NPC).Materials and MethodsNPC patients were extracted from the Surveillance, Epidemiology, and End Results database between 2010 and 2015. Pathologically confirmed stage T1N0M0 (the 7th edition AJCC) were investigated. Overall survival (OS) and cancer-specific survival (CSS) were compared between the radiotherapy and chemoradiotherapy groups using the Kaplan-Meier method and propensity score matching (PSM) analyses.ResultsThis study included 91 (40.27%) patients in the chemoradiotherapy group and 135 (59.73%) patients in the radiotherapy group. Before PSM, chemoradiotherapy was associated with worse 3-year OS (74.31 vs 87.23%; P = 0.025) and 5-year OS (64.28 vs 83.12%; P = 0.001) compared to those associated with radiotherapy. Similarly, chemoradiotherapy showed worse 3-year CSS (87.01 vs 96.97%; P = 0.028) and 5-year CSS (80.39 vs. 96.97%; P = 0.002) than those of radiotherapy. After PSM, chemoradiotherapy revealed worse 5-year OS (63.10 vs. 82.49%; P = 0.031) and CSS (80.95 vs. 93.70%; P = 0.016) than radiotherapy. The multivariate regression analysis revealed that chemoradiotherapy was an independent risk prognostic factor for OS and CSS before and after PSM.ConclusionRadiotherapy alone is recommended for stage I NPC patients.

Abstract Background: The value of maximal lymph nodal diameter in staging system of nasopharyngeal carcinoma (NPC) is not well established.Methods: NPC patients were extracted from SEER database between 2004 and 2016. Overall survival (OS) and cancer-specific survival (CSS) were compared among three groups based on the maximal lymph nodal diameter: ≤3.0 cm, >3.0-6.0 cm, and >6.0 cm. Included patients were randomly divided into training set and validated set with 1:1 ratio. In training set, X-tile plots were created by dividing maximal lymph nodal diameter into three populations. All possible divisions of the maximal lymph nodal diameter were assessed. Two cut-off values were calculated by the X-tile plots in training set. The two cut-off values were evaluated in validated set.Results: The 10-year OS and CSS were different between the three groups. Multivariate regression analysis revealed that maximal lymph nodal diameter >6.0 cm was an independent risk prognostic factor for OS (hazard ratio [HR]=1.91, 95% confidence interval [CI]: 1.51-2.43; P<0.001) and CSS (HR=1.99, 95% CI: 1.51-2.61; P<0.001). The cut-off values of maximal lymph nodal diameter were 1.3 cm and 5.0 cm using X-tile plots in the training set. In the validated set, the maximal lymph nodal diameter >5.0 cm was a risk prognostic factor for OS and CSS.Conclusions: The maximal lymph nodal diameter of 5.0 cm may be a reasonable cut-off value for N stage.

Abstract Background: Small cell carcinoma (SmCC) of cervix was a rare neoplasm with little recognition. Population-based study describing difference in characteristics and outcomes between SmCC and squamous cell carcinoma (SCC), usual type, was limited. Here, we used the Surveillance, Epidemiology, and End Results (SEER) database to compare SmCC with SCC and investigated the prognostic values of the clinicopathological characteristics and survival outcomes in SmCC of cervix.Methods: Patients diagnosed with cervical SmCC and SCC in SEER database from 2004-2015 were enrolled in analysis. Propensity-score matching analysis (PSM) was used to balance baseline characteristics between patients who were cervical SmCC and those who were cervical SCC. Cox regression models and Kaplan-Meier methods were conducted to analyze survival data before and after PSM. Stratified analyses were performed to investigate the risk of mortality at different stage. Results: In total, 25345 patients including 287 cervical SmCC patients and 25058 cervical SCC patients were enrolled our analysis. Both histological subtypes were more common in unmarried women and in white populations. Compared with cervical SCC patients, cervical SmCC patients showed a higher rate of larger tumor size (tumor size ≥4 cm, 33.8% vs 51.9%, P<0.001), higher grade disease (grade III-IV, 32.2% vs 58.9%, P<0.001), regional lymph node involvement (22.5% vs 49.5%, P<0.001) and distant metastasis (10.3% vs 32.4%, P<0.001). Before PSM, multivariate regression model revealed that SmCC histology (P<0.001) and advanced FIGO stages (P<0.001) were principal prognostic factors of poor survival for cervical patients. After PSM, 1060 patients in SCC group were 4:1 matched with 278 patients in SmCC group. Multivariate regression model in PSM cohort showed histology and FIGO stage were crucial prognostic factors for survival. Kaplan-Meier survival curves clearly showed that cervical SmCC patients had worse survival than that of patients with SCC in all stages, stage I-II, III, IV before and after PSM analysis.Conclusion: Compared to patients with cervical SCC, those with cervical SmCC showed a worse survival before and after adjustment baseline characteristic in all stages. SmCC was an independent poor prognostic factor in cervical cancer patients.

The complaint of fatigue is common in community, primary care, and psychiatric settings. Fatigue is often associated with depression and psychosocial stress. This report investigated the role of alexithymia and depression in fatigue as reported in a sample of 151 psychiatric outpatients (75 men and 76 women) who completed all scales. The mean age of the sample was 45.5 yr. ( SD = 12.5), and mean education was 16.2 yr. ( SD = 2.4). Fatigue was inversely correlated with education (–.16) and positively correlated with depression (.44), anxiety (.30), and alexithymia (.35). However, in a multivariate regression analysis, only depression and alexithymia remained significant ( p ≤ .01).

Background Arterial stiffness assessed by carotid-femoral pulse wave velocity (PWV) is an independent predictor of cardiovascular morbidity and mortality. We aimed to investigate how various measures of obesity affect arterial stiffness. Methods We conducted a population-based cross-sectional survey in 8,042 South Indians above the age of 20 years. Following completion of a detailed medical history questionnaire, all participants underwent haemodynamic screening including brachial and central blood pressure, and PWV measurements using a high-fidelity applanation tonometry. The study included anthropometric measurements and fasting blood for total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) and blood glucose (BG) levels. After the exclusion of people with previous history of diabetes, hypertension and dyslipidemia on drug therapy, 5,841 subjects (mean age 41.6 years; 58% women) constituted the study sample Results In an univariate analysis, PWV correlated positively with age, mean blood pressure (MAP), heart rate (HR), body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), body fat percent (BF%), TC, TG, LDL and BG levels (P <0.001) and negatively with HDL levels (P=0.005). In a multivariate regression analysis, majority of the PWV variability in the model was accounted for by MAP and age, (cumulative adjusted R2 change of 32.79% as compared to the total adjusted R2 change of 35.25%). However, BMI (β= 0.042; adjusted R2 change=2.83%; p<0.001) independently correlated with PWV and its contribution to the PWV variability was far more significant compared to LDL, BG and TG (cumulative adjusted R2 change=1.08%). Multivariate regression analysis using the WC, WHR, or BF% instead of the BMI continued to demonstrate a significant independent effect of obesity parameters on PWV. Conclusion: In a large a population-based cross-sectional survey the study demonstrates a positive, independent association between obesity parameters and increased arterial stiffness.

This study sought to determine whether chronic hepatitis B or C would modify the association between insulin analogues and hepatocellular carcinoma (HCC) risks. We conducted a nationwide nested case-control study for HCC cases and matched controls from 2003 to 2013 among newly diagnosed type 2 diabetes patients on any antidiabetic agents in Taiwan before and after exclusion of chronic viral hepatitis, respectively. A total of 5832 and 1237 HCC cases were identified before and after exclusion of chronic viral hepatitis, respectively. Incident HCC risks were positively associated with any use of premixed insulin analogues (adjusted odds ratio (OR), 1.27; 95% CI 1.04 to 1.55) among total participants, especially among current users (adjusted OR, 1.45; 95% CI 1.12 to 1.89). However, the association between HCC occurrence and premixed insulin analogues diminished among participants without chronic viral hepatitis (adjusted OR, 1.35; 95% CI 0.92 to 1.98). We also observed a significant multiplicative interaction between chronic viral hepatitis and premixed insulin analogues on HCC risks (P = 0.010). Conclusions: Chronic viral hepatitis signifies the role of premixed insulin analogues in HCC oncogenesis. We recommend a closer liver surveillance among patients prescribed premixed insulin analogues with concomitant chronic viral hepatitis.

Abstract Purpose Irisin is a newly discovered adipo-myokine known for having significant effects on body metabolism. Currently, there is a discussion regarding the relation between thyroid function and irisin concentration. This study was designed to evaluate the influential role of levothyroxine replacement therapy on circulating levels of irisin in patients with recently onset hypothyroidism following total thyroidectomy. Methods Circulating levels of thyroid hormones, irisin and other metabolic parameters, were assessed in 40 recently thyroidectomized patients (34 females, mean age 50.1 ± 15.2 years) at baseline (5–7 day after surgery) and after 2 months under replacement therapy with levothyroxine. Results At baseline, circulating levels of thyroid hormones were indicative of hypothyroidism (TSH 12.7 ± 5.0 μU/mL, FT3 1.9 ± 0.7 pg/mL, FT4 8.7 ± 3.6 pg/mL). Mean serum irisin concentrations significantly increased after 2 months under replacement therapy with levothyroxine (from 2.2 ± 0.6 to 2.9 ± 0.6 μg/mL, p < 0.0001). Variations of circulating levels of irisin under levothyroxine replacement therapy were directly correlated with those of FT3 (Rho = 0.454, p = 0.0033) and FT4 (Rho = 0.451, p = 0.0035). Multivariate regression analysis revealed that changes in thyroid hormones concentrations explained up to 10% of the variations of serum irisin levels under levothyroxine replacement therapy (FT3 R2 = 0.098, FT4 R2 = 0.103). Conclusion Our study suggests that levothyroxine replacement therapy mildly influences irisin metabolism in patients with recently onset hypothyroidism following total thyroidectomy.

202 Background: Hepatocellular carcinoma (HCC) is a significant source of morbidity and mortality amongst the elderly population. In appropriately selected patients, surgery is known to confer a survival advantage. Octagenarians, however, given their remaining life expectancy may receive limited benefit from surgery. Nevertheless, insufficient information is available in the literature on the survival benefit of surgery in octagenarians with HCC. Methods: Octogenarians with HCC were selected from the Surveillance, Epidemiology, and End Results (SEER) database between 1998 and 2009. We evaluated patients who underwent surgical resection and those that declined to assess the impact surgery has on overall survival in this population. Results: A total of 8,614 with HCC were identified in the SEER database, of which surgery was recommended for 3,529 (41%). A total of 1,002 patients (28%) underwent surgery and 2,497 (71%) declined. Although there was a trend towards improved survival in the surgery group (7.91 months) vs the non-surgical group (7.03 months), there was no statistically significant difference in survival between the two groups (p = 0.09). Conclusions: Our study demonstrates that octagenarians as a whole do not experience a survival benefit from surgical resection for HCC. Subgroup analysis, however, may ultimately identify benefit in specific disease stages or patients with fewer comorbidities.

AbstractBackgroundThe role of neutrophil and lymphocyte counts as predictors of prognosis in Community Acquired Pneumonia (CAP) has not been appropriately studied.MethodsThis was a retrospective study to evaluate by multivariate regression analysis, the association between neutrophil and lymphocyte counts with mortality at 30-days post discharge in two large cohorts of hospitalized patients with CAP and no prior immunosupression: a multicentric with 1550 patients recruited at 14 hospitals in Spain and a unicentric with 2840 patients recruited at the Hospital Clinic-Barcelona.FindingsThe unicentric cohort accounted with a higher proportion of critically ill patients: 586 (20·6%) vs 131 (8·5%) and non survivors 245 (8·6%) vs 74 (4·8%). Lymphopenia (< 1000 lymphocytes/mm3) was present in the 52·8% of the patients in both cohorts. A sub-group of lymphopenic patients, those with lymphocyte counts below decil 3 (677 lymphocytes/mm3 in the multicentric cohort and 651 lymphocytes/mm3 in the unicentric one), showed > 2-fold increase in the risk of mortality, independently of the CURB-65 score, critical illness and receiving an appropriated antibiotic treatment: (OR [CI95%], p) (2·18 [1·21- 3·92], 0·009) and (2·33 [1·61-3·33], <0·001) respectively. Neutrophil counts were not associated with mortality risk.InterpretationLymphopenia is present in a half of the patients with CAP needing of hospitalization, in absence of antecendents of immunosupression. Lymphopenic CAP with lymphocyte counts < 664 lymphocytes/mm3 constitutes a particular immunological phenotype of the disease which is associated to an increased risk of mortality.FundingCibeRes, 2009 Support to Research Groups of Catalonia 911, IDIBAPS, SEPAR, SVN
