Risk Factors for Second Malignancies after Transplantation Differ between Allogeneic and Autologous Transplantation.

Abstract Survivors of hematopoietic stem cell transplantation (HSCT) are at risk for second malignant neoplasms (SMN). We undertook this analysis to ascertain whether risk of SMN was comparable in survivors of allogeneic and autologous transplantation. Among 8662 transplant recipients treated at the Fred Hutchinson Cancer Research Center between November 1969 and April 2004, who survived at least 100 days post transplant, there were 1743 autologous and 6919 allogeneic HSCT recipients. Within this cohort, there were 56 SMNs among the autologous and 224 among the allogeneic recipients. Cumulative incidence of SMN at 10 years post-HSCT was 2.6% in the allogeneic and 4.2% in the autologous HSCT survivors. A multivariate Cox regression model adjusted for current age, TBI, gender and length of follow-up was fit and the hazard ratio (HR) for SMN for the allogeneic transplant survivors was 0.7 (95% confidence interval {CI} 0.5, 1.0) compared to the autologous transplant survivors (reference group), suggesting that the adjusted hazard of SMN is higher for autologous than for allogeneic HSCT recipients. Risk factors differed between the two groups. For survivors of autologous transplantation, in multivariate Cox regression models, only age > 18 years at transplant was associated with decreased risk of SMN (<18 years HR = 1.0; 18–39 years HR = 0.04; 40+ years HR = 0.004). Use of total body irradiation (TBI) was not significantly associated with risk among the autologous HSCT recipients. For allogeneic transplant survivors, increased risk of SMN was associated with TBI and the effect of TBI was stronger for younger (<18 years at HSCT: HR = 4.6; 95% CI 1.6, 13.5) than for older (≥18 years; HR = 1.5; 95% CI 1.0, 2.3) HSCT recipients (interaction p = 0.04) in multivariate Cox regression models. Risk was also increased after acute graft versus host disease (HR = 1.4; 95% CI 1.0, 1.9) and with ongoing follow-up time, with HRs of 1.7 (95% CI 1.1, 2.5) at 10 – 14 years, 2.2 (95% CI 1.3, 3.7) at 15–19 years and 2.6 (95% CI 1.2, 5.4) at 20+ years of follow-up. Unrelated HSCT also increased risk of SMN (HR = 1.4; 95% CI 1.0, 2.0). In adjusted analyses, risk of SMN thus appears slightly lower in allogeneic versus autologous transplant survivors, and risk factors appear different between the two groups. Attention should focus on modifiable risk factors in both groups. Particularly in autologous transplant survivors, the relative contribution of pre-transplant exposures must be established.

BackgroundThe association between pulse pressure (PP) and the risk of first ischaemic stroke (IS) is inconsistent. Therefore, we evaluated the association between PP and the risk of first IS among elderly hypertensive population in China.MethodsThis was a retrospective cohort study. Patients with hypertension and aged ≥60 years were recruited. Multivariate Cox regression was performed to evaluate the association between PP and the risk of IS. We further stratified the regression models into subgroups and test for interaction to assess whether the associations were modified by other covariates.ResultsA total of 3315 patients with hypertension (44.49% male; mean age 71.41±7.20 years) were included, and 206 cases of IS occurred with a median follow-up of 5.5 years. The results showed that per SD mm Hg increment in PP was associated with a 17% (95% CI 1.05 to 1.40, p=0.0172) increased risk of IS. Moreover, the HR of IS for the highest quartile of PP was 1.46 (95% CI 1.18 to 1.73, p=0.0011, p for trend <0.001) comparing with the lowest quartile of PP. Subgroup analysis showed that population aged ≥70 years, male, patients with smoking or drinking habit, diabetes at baseline, being overweight, with uncontrolled blood pressure or did not take antihypertensive drugs have a higher risk for IS.ConclusionsWe found that PP was significantly associated with IS and was an independent risk factor for IS.

Limited data are available regarding the association of major dietary patterns and risk of cardiovascular disease (CVD) in Middle Eastern countries. We aimed to evaluate the association of major dietary patterns, using factor analysis, with the risk of CVD. Participants without CVD (n = 2284) were recruited from the Tehran Lipid and Glucose Study and were followed for a mean of 4.7 years. Dietary intake of participants was assessed at baseline (2006–2008); biochemical variables were evaluated at baseline and follow-up examination. Multivariate Cox proportional hazard regression models, adjusted for potential confounders, were used to estimate risk of CVD across tertiles of dietary pattern scores. Linear regression models were used to indicate association of dietary pattern scores with changes of CVD risk factors over the study period. Two major dietary patterns, Western and traditional, were identified. During a mean 4.7 ± 1.4 years of follow-up, 57 participants experienced CVD-related events. In the fully adjusted model, we observed an increased risk of CVD-related events in the highest compared to the lowest tertile category of Western dietary pattern score (HR = 2.07, 95% CI = 1.03–4.18, P for trend = 0.01). Traditional dietary pattern was not associated with incidence of CVD or CVD risk factors. A significant association was observed between the Western dietary pattern and changes in serum insulin (β = 5.88, 95% CI = 0.34–11.4). Our findings confirm that the Western dietary pattern, characterized by higher loads of processed meats, salty snacks, sweets, and soft drinks, is a dietary risk factor for CVD in the Iranian population.

ObjectiveTo investigate whether acute convexity subarachnoid hemorrhage (cSAH) associated with acute lobar intracerebral hemorrhage (ICH) increases the risk of ICH recurrence in patients with cerebral amyloid angiopathy (CAA).MethodsWe analyzed data from a prospective cohort of consecutive survivors of acute spontaneous lobar ICH fulfilling the Boston criteria for possible or probable CAA (CAA-ICH). We analyzed baseline clinical and MRI data, including cSAH (categorized as adjacent or remote from ICH on a standardized scale), cortical superficial siderosis (cSS), and other CAA MRI markers. Multivariable Cox regression models were used to assess the association between cSAH and recurrent symptomatic ICH during follow-up.ResultsWe included 261 CAA-ICH survivors (mean age 76.2 ± 8.7 years). Of them, 166 (63.6%, 95% confidence interval [CI] 57.7%–69.5%) had cSAH on baseline MRI. During a median follow-up of 28.3 (interquartile range 7.2–57.0) months, 54 (20.7%) patients experienced a recurrent lobar ICH. In Cox regression, any cSAH, adjacent cSAH, and remote cSAH were independent predictors of recurrent ICH after adjustment for other confounders, including cSS. Incidence rate of recurrent ICH in patients with cSAH was 9.9 per 100 person-years (95% CI 7.3–13.0) compared with 1.2 per 100 person-years (95% CI 0.3–3.2) in those without cSAH (adjusted hazard ratio 7.5, 95% CI 2.6–21.1).ConclusionIn patients with CAA-related acute ICH, cSAH (adjacent or remote from lobar ICH) is commonly observed and heralds an increased risk of recurrent ICH. cSAH may help stratify bleeding risk and should be assessed along with cSS for prognosis and clinical management.

Abstract Background Weight gain commonly occurs among HIV-infected (HIV+) adults initiating modern ART regimens, and obesity is increasingly reported in this population. However, data regarding specific risk factors for obesity development after ART initiation are conflicting. Methods We retrospectively analyzed data from a cohort of HIV+ adults who initiated ART between January 1, 2000 and December 31, 2015 in Rio de Janeiro, Brazil. Body mass index (BMI) was assessed at ART initiation. Participants who were non-obese (BMI < 30kg/m2) at baseline and had ≥90 days of ART exposure were followed for development of obesity. Participants were censored at the time of obesity diagnosis or at end of follow-up (defined as death, loss to follow-up, end of study period or 2 years after their last weight measurement). Incidence rates were estimated using Poisson regression models and risk factor assessment was calculated using Cox regression models accounting for death and loss to follow-up as competing risks. Results Participants (n = 1,794) were 61.3% male, 48.3% white and had a median age of 36.3 years. At ART initiation, participants had a median BMI of 22.6kg/m2 and BMI category distribution was: underweight 14%, normal weight 56%, overweight 22% and obese 8%. Of the 1,567 non-obese participants followed after ART initiation, 76% gained weight, 44% increased their BMI category and 18% developed obesity. Median BMI at the end of follow-up was 24.7kg/m2 (0.4kg/m2 median annual change), the obesity incidence rate was 37.4 per 1000 person-years and the median time to obesity diagnosis was 1.9 years (vs. 4.7 years of follow-up for participants remaining non-obese). Factors associated with obesity after ART initiation included younger age at ART initiation, female sex, higher baseline BMI, lower baseline CD4+ T lymphocyte count, higher baseline HIV-1 RNA, having an integrase inhibitor as the most-used ART core drug and having diagnoses of hypertension and diabetes mellitus (Figure). Conclusion Obesity following ART initiation is frequent among HIV+ adults, with rates increasing in recent years. Both traditional (female sex) and HIV-specific (more advanced HIV disease, integrase inhibitor use) risk factors contribute importantly to obesity incidence following ART initiation.

Abstract Background: The global incidence of thyroid cancer (TC) has risen considerably during the last three decades, while prognosis is generally favorable. We assessed the long-term all-cause mortality in TC survivors compared to the general population, and its association with cardiovascular risk factors. Methods: Individuals diagnosed with TC during 2001-2014 (TC group) and age- and sex-matched individuals from the same Israeli healthcare system without thyroid disease or a cancer history (non-TC group) were compared. Cox regression hazard ratios (HRs) and 95% confidence intervals (95%CIs) for all-cause mortality were calculated by exposure status. Results: During a 15-year follow-up (median 8 years), 577 TC survivors out of 5,677 (10.2%) TC patients and 1,235 individuals out of 23,962 (5.2%) non-TC patients died. The TC survivors had an increased risk of all-cause mortality (HR=1.89, 95%CI 1.71-2.10), after adjusting for cardiovascular risk factors already present at follow-up initiation. This increased risk was most pronounced in the 55- to 64-year-old age group (HR=1.49, 95%CI 1.33-1.67). The TC survivors who died by study closure had more hypertension (14.6% vs. 10.3%, P = 0.002), more dyslipidemia (11.4% vs. 7.2%, P < 0.001), and more cardiovascular disease (33.6% vs. 22.3%, P = 0.05) compared to those who died in the non-TC group. Conclusions: This large cohort study showed higher all-cause mortality with a higher prevalence of hypertension, dyslipidemia, and cardiovascular disease among TC survivors compared to matched non-TC individuals. Primary and secondary prevention of cardiovascular risk factors in TC survivors is mandatory.

ObjectiveIn this report, we determine the cumulative incidence of symptomatic cardiac ischaemia and its risk factors among European 5-year childhood cancer survivors (CCS) participating in the PanCareSurFup study.MethodsEight data providers (France, Hungary, Italy (two cohorts), the Netherlands, Slovenia, Switzerland and the UK) participating in PanCareSurFup ascertained and validated symptomatic cardiac events among their 36 205 eligible CCS. Data on symptomatic cardiac ischaemia were graded according to the Criteria for Adverse Events V.3.0 (grade 3–5). We calculated cumulative incidences, both overall and for different subgroups based on treatment and malignancy, and used multivariable Cox regression to analyse risk factors.ResultsOverall, 302 out of the 36 205 CCS developed symptomatic cardiac ischaemia during follow-up (median follow-up time after primary cancer diagnosis: 23.0 years). The cumulative incidence by age 60 was 5.4% (95% CI 4.6% to 6.2%). Men (7.1% (95% CI 5.8 to 8.4)) had higher rates than women (3.4% (95% CI 2.4 to 4.4)) (p<0.0001). Of importance is that a significant number of patients (41/302) were affected as teens or young adults (14–30 years). Treatment with radiotherapy/chemotherapy conferred twofold risk (95% CI 1.5 to 3.0) and cases in these patients appeared earlier than in CCS without treatment/surgery only (15% vs 3% prior to age 30 years, respectively (p=0.04)).ConclusionsIn this very large European childhood cancer cohort, we found that by age 60 years, 1 in 18 CCS will develop a severe, life-threatening or fatal cardiac ischaemia, especially in lymphoma survivors and CCS treated with radiotherapy and chemotherapy increases the risk significantly.

We investigated the risk of depression in colorectal cancer (CRC) patients and associated risk factors. The 1324 patients with CRC and 6620 matched cancer-free participants from the Diet, Cancer and Health study were followed for up to 16 years for either a first hospitalization for depression or antidepressant prescription after diagnosis of CRC cancer or study entry date. Information on the outcome and covariates was retrieved from the Danish Colorectal Cancer Group database, the national health registries and questionnaires. Cumulative incidence of depression was estimated, and Cox regression models were used to evaluate the association between risk factors and depression incidence. During follow-up, 191 (14.4%) patients with CRC and 175 (2.6%) cancer-free comparison persons experienced depression. After adjustments, in the first year after cancer diagnosis, patients with CRC had a 12-fold higher hazard compared with the cancer-free population (HR, 12.01; 95% CI, 7.89–18.28). The risk decreased during follow-up but remained significantly elevated with an HR of 2.65 (95% CI, 1.61–4.36) after five years. Identified risk factors were presence of comorbidities, advanced disease stage and use of radiotherapy, while life style factors (pre-cancer or at diagnosis) and chemotherapy did not seem to contribute to the increased risk.

Abstract Background: It has been reported that obesity and diabetes are both the risk factors for the development of cardiovascular diseases (CVD). However, recent articles reported that compared with BMI, waist circumference (WC) can better reflect obesity, more closely related to visceral fat tissue which is positively associated with an increased risk of cardiovascular death. Moreover, few studies have both investigated the prognostic value of both WC and diabetes during a long-term follow up. We aimed to investigate whether higher level of WC measurements and diabetes were able to predict cardiovascular mortality in general population.Methods: In this prospective cohort study, a total of 1521 consecutive subjects free of clinical cardiovascular disease were included. The end point was cardiovascular death. The Kaplan-Meier method and Cox regression models were used to evaluate the cumulative risk of outcome at different WC levels with or without diabetes.Results: During a median follow up of 9.2 years, there were 265 patients had the occurrence of cardiovascular death. Kaplan-Meier survival estimates indicated that the patients with higher levels of WC (WC>94cm) coexist with diabetes had significantly increased risk of cardiovascular death (log-rank p＜0.05). After adjustment for potential confounders, multiple COX regression models showed that the incidence of cardiovascular death was significantly higher when patients with high WC coexisted with DM (HR 3.78; 95% CI: 3.35–3.98; p＜0.001).Conclusion: Patients with high WC and diabetes represent a high-risk population for cardiovascular death. WC and diabetes may provide incremental prognostic value beyond traditional risks factors.

Purpose The number of breast cancer survivors at risk of developing contralateral breast cancer (CBC) is increasing. However, ambiguity remains regarding risk factors and prognosis for women with CBC. Patients and Methods In a cohort of 42,670 women with breast cancer in the Uppsala/Örebro and Stockholm regions in Sweden in 1992 to 2008, we assessed risk factors for and prognosis of metachronous CBC by using survival analysis. Breast cancer–specific survival for women with CBC was evaluated and compared with results for women with unilateral breast cancer (UBC) by using time-dependent Cox-regression modeling. Results An increased risk for CBC was observed among women who had primary breast cancer with ≥ 10 involved lymph nodes compared with node-negative women (adjusted hazard ratio [HR], 1.8; 95% CI, 1.2 to 2.7). The prognosis was poorer in women with CBC than with UBC. The hazard of dying from breast cancer was especially high for women with a short interval time to CBC (adjusted HR, 2.3; 95% CI, 1.8 to 2.8 for CBC diagnosed ≤ 5 years v UBC) and gradually decreased with longer follow-up time but remained higher than the hazard originating from the primary tumor for ≥ 10 years. Conclusion Women with advanced-stage primary breast cancer had an increased risk of developing CBC. CBC is associated with an increased risk of dying from breast cancer throughout a long period of follow-up after the primary tumor. Our findings suggest that the event of CBC marks a new clinical situation in terms of investigations for metastases, treatment considerations, and follow-up strategy.
