Intermediate (One-Year) Outcomes of Cardiogenic Shock Patients Supported by ECMO Due to Decompensated Heart Failure and Acute Myocardial Infarction

<h3>Purpose</h3> Cardiogenic shock patients who are supported by ECMO have high mortality and morbidity. We evaluated the 1-year outcomes in ECMO supported patients with decompensated heart failure (DHF) or acute myocardial infarction (AMI), including death, heart transplantation (HT), left ventricular assist device (LVAD) implantation as well as dependency on hemodialysis or ventilation. <h3>Methods</h3> Patients supported by ECMO due to DHF or AMI registered in the Spectrum Health ECMO registry were included in this study. Clinical, echocardiographic, laboratory and hemodynamic characteristics were obtained in all patients. Survival analysis using Kaplan-Meier curves for the combined outcome of death, heart transplantation (HT) and LVAD implantation were developed. These outcomes were compared between DHF and AMI patients. The frequency of renal replacement therapy or ventilator dependency on 1-year survivors was calculated. <h3>Results</h3> A total of 283 patients received ECMO, 228 due to DHF and 55 due to AMI. Of these, 22 patients received LVAD, and 1patient received HT. A total of 174 patients died (including 6 LVAD patients and 1 HT patient) within 1 year of ECMO. Patients with AMI had higher troponin (2.5 ng/dL (0.49 - 7.85) vs. 1.4 ng/dL (0.15 - 4.6), p=0.013), lower total bilirubin 0.65 mg/dL (0.4 - 1.12) vs. 0.8 mg/dL (0.5 - 1.6), p=0.025), higher ALT (117 IU (61- 225) vs. 48 IU (29 - 171), p = 0.003), lower creatinine (1.35 mg/dL ± 0.75 vs. 1.6 mg/dL ± 1.17, p=0.006), lower inotropic score (7 (1 - 18) vs. 9 (4 - 20), p=0.022). The combined endpoint survival free of HT or LVAD implantation at 1-month was 45.5% vs. 38.6% for AMI and DHF, respectively. There was a small but continued decrease in the survival of combined outcome at 1 year (36.4% vs. 32%, p=0.607, Figure 1). The 1-year survival probability free of the combined outcome for those patients who survived 30 days was 81.4% vs. 81.7% for AMI and DHF, respectively. Of the 92 patients who were alive at one year, 5 (5.4%) had end stage renal disease and were receiving hemodialysis and 3 (3.2%) were dependent on a ventilator. <h3>Conclusion</h3> The 1-year survival free of HT or LVAD in AMI or DHF patients requiring ECMO is low. This is predominantly driven by the outcome on the first 30 days after ECMO implantation. A small proportion of 1-year survivors have end stage renal disease or are dependent on mechanical ventilation.

Twenty-year longitudinal follow-up after liver transplantation: a single-center experience with 251 consecutive patients.

BackgroundThe outcomes of liver transplantation (LT) have improved, but actual 20-year survival data have rarely been presented.MethodsLongitudinal follow-up data of 20-year LT survivors were retrospectively analyzed. The LT database of our institution was searched to identify patients who underwent primary LT from January 2000 to December 2001. The study cohort of 251 patients was divided into three groups 207 adults who underwent living donor LT (LDLT), 22 adults who underwent deceased donor LT (DDLT), and 22 pediatric patients who underwent LT.ResultsHepatitis B virus–associated liver cirrhosis and biliary atresia were the most common indications for adult and pediatric LT, respectively. Seven patients required retransplantation, including six who underwent DDLT and one who underwent LDLT. Twenty-two patients died within 3 months after LT and 69 died at later intervals. The overall survival rates at 1, 3, 5, 10, and 20 years were 86.4%, 79.6%, 77.7%, 72.8%, and 62.6%, respectively, in the adult LDLT group; 86.4%, 72.7%, 72.7%, 72.7%, and 68.2%, respectively, in the adult DDLT group; and 86.4%, 86.4%, 81.8%, 81.8%, and 77.3%, respectively, in the pediatric LT group (P=0.545). Common immunosuppressive regimens at 20 years included tacrolimus monotherapy, tacrolimus–mycophenolate dual therapy, cyclosporine monotherapy, and mycophenolate monotherapy.ConclusionsThe present study is the first report of actual 20-year survival data from a Korean high-volume LT center. The graft and patient survival outcomes reflected the early experiences of LT in our institution, with long-term outcomes being similar regardless of graft type and patient age.

Satisfaction with permanent changes after cancer surgery: From personal satisfaction of gastric cancer survivors with post-gastrectomy weight loss

This study assessed the personal satisfaction of gastric cancer survivors with post-gastrectomy weight loss. The responses were analyzed in relation to the actual weight status based on two general criteria-preoperative weight and the World Health Organization (WHO) weight classification-as part of an attempt to identify patterns of satisfaction with weight loss. Survivors with significant postoperative weight loss (≥8%) were identified among 1- and 5-year survivors, and were divided into obese/non-obese weight losers (WLs) based on the WHO definition of obesity. For comparison, those with minimal weight change (not exceeding±3%) at each time period were identified (non-WLs).The EORTC QLQ-C30 and -STO22 questionnaires were used to monitor quality of life (QoL). Responses to an item in the EORTC QLQ-STO22, inquiring about personal concerns with weight loss, were used to assess personal satisfaction with weight changes. Except for the QoL disadvantages of non-obese WLs in anxiety (P=0.011) of 1-year survivors and in emotional functioning (P=0.039) of 5-year survivors, there was no significant difference in QoL changes between groups. Regarding personal satisfaction with decreased body weight, non-obese WLs continued to show dissatisfaction (P<0.001) unlike obese WLs, who enjoyed satisfaction comparable to non-WLs long after surgery. Compared with non-obese WLs who expressed dissatisfaction with current weight, obese WLs were satisfied with their current weight several years after surgery. Patient satisfaction with surgical changes may depend on the availability of reasonable grounds that suggest a positive interpretation of surgically altered status.

Extent of mural thrombus is not associated with increased 5-year mortality following elective AAA repair.

Mural thrombus in abdominal aortic aneurysm (AAA) has been associated with increased rates of aneurysm growth as well as adverse cardiovascular events. The extent of mural thrombus in thoracoabdominal aortic aneurysms has recently been linked to 1-year mortality following endovascular repair and has been hypothesized as a marker for reduced cardiac reserve. This study investigates whether the extent of mural thrombus in infra-renal AAA is associated with 5-year mortality following elective repair. Retrospective review of all patients undergoing elective infra-renal AAA repair at a single academic medical center between 2007 and 2016 was performed. The following variables at the time of surgery were investigated for association with 5-year mortality: age, sex, ethnicity, insurance status and co-morbidities, repair type, renal insufficiency, end-stage renal disease on dialysis, history of smoking, coronary artery disease, congestive heart failure, diabetes mellitus, hypertension, stroke, chronic obstructive pulmonary disease, body mass index category, AAA diameter, and ratio of aortic thrombus to total aneurysm diameter. Amongst 427 patients undergoing infra-renal AAA repair during the study period, 232 met extensive inclusion criteria. Univariate analysis found mean age (76 vs 72, p < 0.01), age cohort over 72 years (OR = 1.9, p = 0.04), renal insufficiency (OR = 3.1, p < 0.01), ESRD (OR = 6.5, p < 0.01), AAA diameter 6cm or greater (OR = 2.3, p < 0.01), and mean AAA diameter (61.36vs 56.99mm, p < 0.01) all predictive of 5-year mortality. Multivariate analysis revealed renal insufficiency (p < 0.01) and AAA diameter 6cm or greater (p = 0.03) to be significantly associated with 5-year mortality. The extent of mural thrombus was identical between 5-year survivors and non-survivors. The mean inner to outer AAA diameter was 0.65 in the survivor cohort and 0.64 in the mortality cohort. Inner to outer ratio of < 0.5 was identified in 23% of 5-year survivors and 27% of the mortality group. In our experience, the extent of mural thrombus in AAA does not influence long-term survival after elective repair. AAA repair may provide protection against circulating components of mural thrombus which have the potential to promote atherosclerotic-related adverse events. Patients with renal insufficiency and larger AAA have increased risk of mortality 5 years after elective repair.

Conditional survival estimates for merkel cell carcinoma reveal the dynamic nature of prognostication.

Conditional survival (CS) analysis has emerged as a dynamic prognostication methodology. The goal of this study was to determine disease-specific CS rates in Merkel cell carcinoma (MCC). This retrospective study included patients with MCC from the Surveillance Epidemiology and End Results (SEER) registry (1988-2016). Stage-specific 5-year MCC-specific CS rates for study and survivor cohorts were estimated, and the significance of clinicopathologic factors to predict 1-year MCC-specific death was evaluated using multivariate logistic regression. Within stage, 5-year CS survival rates improved with increasing survivorship. Pathologic Stage I patients had the highest 5-year CS rate at diagnosis (89.1%) but the smallest increase over time (96% among 5-year survivors). Stage IV patients experienced the greatest change in 5-year CS rates from 25.4% (at diagnosis) to 88% (5-year survivors). At diagnosis stage, age, sex, and primary site were all significantly associated with 1-year MCC-related death in the multivariate analysis. In contrast, among 5-year survivors only sex and age at diagnosis were significant predictors. MCC CS rates improved across all disease stages over time. Additionally, the relationships of prognostic factors with 1-year MCC-death changed with increasing survivorship. This perspective can provide a foundation for informed decision-making.

Retroperitoneal Lymph Node Metastasis in Gallbladder Cancer: As Bad as Distant Metastasis.

Ashish SinghBackground Regarding gallbladder cancer (GBC) there is conflicting evidence in the literature whether retroperitoneal lymph nodal metastases (RLNM) should be considered as regional nodal metastasis or as distant metastasis (DM) and the jury is out on radical curative surgery in presence of RLNM. This is an analysis of GBC patients, to see the effect of RLNM on survival and to compare with that of patients with DMs. Methods A retrospective analysis of a prospective database of patients of GBC with RLNM (interaortocaval and paraaortic) or DM on frozen section biopsy at surgery, between January 2013 and December 2018. Data was analyzed using the Statistical Package for the Social Sciences software (version 22.0). Survival in these two groups (RLNM and DM) was compared with log-rank test. A p -value of < 0.05 was considered significant. Results A total of 235 patients with ostensibly resectable GBC underwent surgical exploration. The planned curative resection was abandoned in 91 (39%) patients because of RLNM ( n = 20, 9%) or DM ( n = 71, 30%) on frozen section biopsy. Demographic profile and blood parameters were similar. The median survival for RLNM and DM groups were 5 (range 2-26) and 6 (range 2-24) months, respectively, with no significant difference on log-rank test ( p = 0.64). There was no 3-year or longer survivor in either group. Conclusion Due to similar poor survival in presence of RLNM or DM, RLNM should be considered as the equivalent of DM. This study strengthens evidence to avoid curative surgery in patients with RLNM. These lymph nodes should be sampled preoperatively, if suspicious on imaging, for fine-needle aspiration cytology and at surgery, as a routine for frozen section histological examination before initiating curative resection to avert a futile exercise.

Long-term Survival after Hematopoietic Cell Transplant for Sickle Cell Disease Compared to the United States Population

Hematopoietic cell transplant for sickle cell disease is curative but is associated with life threatening complications most of which occur within the first 2 years after transplantation. In the current era with interest in gene therapy and gene editing we felt it timely to report on sickle cell disease transplant recipients who were alive for at least 2-year after transplantation, not previously reported. Our objectives were to (1) report the conditional survival rates of patients who were alive for 2 or more years after transplantation (2) identify risk factors for death beyond 2 years after transplantation and (3) compare all-cause mortality risks to those of an age-, sex- and race-matched general population in the United States. By limiting to 2-year survivors, we exclude deaths that occur as a direct consequence of the transplantation procedure. De-identified records of 1149 patients were reviewed from a publicly available data source and 950 patients were eligible (https://picsure.biodatacatalyst.nhlbi.nih.gov). All analyses were performed in this secure cloud environment using the available statistical software package(s). The validity of the public database was confirmed by reproducing results from an earlier publication. Conditional survival estimates were obtained using the Kaplan-Meier method for the sub-cohort that had survived a given length (x) of time after transplantation. Cox regression models were built to identify risk factors associated with mortality beyond 2 years after transplantation. The standardized relative mortality risk (SMR) or the ratio of observed to expected number of deaths, was used to quantify all-cause mortality risk after transplantation and compared to age, race and sex-matched general population. Person-years at risk were calculated from an anchor date (i.e., 2-, 5- and 7-years) after transplantation until date of death or last date known alive. The expected number of deaths was calculated using age, race and sex-specific US mortality rates. The median follow up was 5 years (range 2-20) and 300 (32%) patients were observed for more than 7 years. Among those who lived for at least 7 years after transplantation the 12-year probability of survival was 97% (95% CI, 92%-99%). Compared to an age-, race- and sex-matched US population, the risk for late death after transplantation was higher as late as 7 years after transplantation (hazard ratio (HR) 3.2; P= .020) but the risk receded over time. Risk factors for late death included age at transplant and donor type. For every 10-year increment in patient age, an older patient was 1.75 times more likely to die than a younger patient (P= .0004). Compared to HLA-matched siblings the use of other donors was associated with higher risk for late death (HR 3.49; P= .003). Graft failure (beyond 2-years after transplantation) was 7% (95% CI, 5%-9%) and graft failure was higher after transplantation of grafts from donors who were not HLA-matched siblings (HR 2.59, P< .0001). Long-term survival after transplantation is excellent and support this treatment as a cure for sickle cell disease. The expected risk for death recedes over time but the risk for late death is not negligible.

Long-Term Risk of Hospitalization for Somatic Diseases Among Survivors of Childhood Acute Lymphoblastic Leukemia.

BackgroundSurvivors of childhood acute lymphoblastic leukemia (ALL) may be at increased long-term risk of hospitalization for somatic diseases. However, large population-based cohort studies with risk estimates for survivors successfully cured without experiencing a relapse or requiring hematopoietic stem cell transplantation (HSCT) are lacking.MethodsDanish and Swedish patients diagnosed with ALL before age 20 years in 1982-2008 were identified in the national cancer registries. Five-year survivors and matched population comparisons without childhood cancer were followed for hospitalization for 120 somatic disease categories in the national hospital registries from 5 years postdiagnosis until 2017, and disease-specific hospitalization rate ratios (RR) were calculated. The mean cumulative count method was used to estimate the mean number of multiple and recurrent disease-specific hospitalizations per individual.ResultsA total of 2024 5-year survivors and 9797 population comparisons were included. The overall hospitalization rate was more than twice as high compared with comparisons (RR = 2.30, 95% confidence interval [CI] = 2.09 to 2.52). At 30 years postdiagnosis, the mean cumulative hospitalization count was 1.69 (95% CI = 1.47 to 1.90) per survivor and 0.80 (95% CI = 0.73 to 0.86) per comparison. In the subcohort without relapse or HSCT (n = 1709), the RR was 1.41 (95% CI = 1.27 to 1.58).ConclusionsSurvivors of childhood ALL were at increased long-term risk for disease-specific hospitalizations; however, in survivors without relapse or HSCT, the rate was only modestly higher than in population comparisons without a childhood cancer. The absolute mean numbers of multiple and recurrent hospitalizations were generally low.

Identifying causal relationships of cancer treatment and long-term health effects among 5-year survivors of childhood cancer in Southern Sweden

BackgroundSurvivors of childhood cancer can develop adverse health events later in life. Infrequent occurrences and scarcity of structured information result in analytical and statistical challenges. Alternative statistical approaches are required to investigate the basis of late effects in smaller data sets.MethodsHere we describe sex-specific health care use, mortality and causal associations between primary diagnosis, treatment and outcomes in a small cohort (n = 2315) of 5-year survivors of childhood cancer (n = 2129) in southern Sweden and a control group (n = 11,882; age-, sex- and region-matched from the general population). We developed a constraint-based method for causal inference based on Bayesian estimation of distributions, and used it to investigate health care use and causal associations between diagnoses, treatments and outcomes. Mortality was analyzed by the Kaplan–Meier method.ResultsOur results confirm a significantly higher health care usage and premature mortality among childhood cancer survivors as compared to controls. The developed method for causal inference identifies 98 significant associations (p < 0.0001) where most are well known (n = 73; 74.5%). Hitherto undescribed associations are identified (n = 5; 5.1%). These were between use of alkylating agents and eye conditions, topoisomerase inhibitors and viral infections; pituitary surgery and intestinal infections; and cervical cancer and endometritis. We discuss study-related biases (n = 20; 20.4%) and limitations.ConclusionsThe findings contribute to a broader understanding of the consequences of cancer treatment. The study shows relevance for small data sets and causal inference, and presents the method as a complement to traditional statistical approaches.

Construction of Novel Prognostic Nomogram for Mucinous and Signet Ring Cell Colorectal Cancer Patients with a Survival Longer Than 5 Years.

PurposeMucinous adenocarcinoma (MA) and signet ring cell carcinoma (SRCC) are aggressive colorectal cancer histological subtypes with dismal prognosis. This study investigated prognostic factors and constructed novel nomograms for MA and SRCC patients who survived for over 5 years to optimize the follow-up regime, especially for early-onset patients.Patients and MethodsData from the Surveillance, Epidemiology, and End Results (SEER) database registered between 2004 and 2018 were extracted. MA and SRCC patients were divided into two groups with survival time of 5 years as a cut-off point. Prognostic factors for overall survival (OS) and cancer-specific survival (CSS) were determined by Cox regression models, and survival curves were plotted by the Kaplan–Meier method.ResultsWe identified 8286 MA patients (45.73%) and 551 SRCC patients (20.32%) who survived for over 5 years. Multivariable Cox analyses identified age, tumor location, N stage, metastasis, CEA level, surgery, and lymph nodes dissection as independent risk factors for MACSS. SRCC was more aggressive and only N2 stage (P = 0.011) and metastasis (P = 0.043) were inversely associated with SRCCSS. Furthermore, we observed that small tumor size, well differentiation, and chemotherapy no longer provided survival benefit to ≥5-year survivors. Therefore, we constructed novel nomograms appropriate for MA patients who survived for over 5 years. The consistency indexes for predicting 10-year OS and CSS were respectively 0.717, 0.712 in the training cohort and 0.727, 0.735 in the validation cohort.ConclusionOur well-calibrated nomograms represent the first clinical prognostic models developed especially for MA patients with a survival longer than 5 years. For both MA and SRCC patients, TNM stage was a stable prognostic factor, while the prognostic values of tumor size, differentiation grade, and chemotherapy changed over time. We are hopeful that our prognostic models will help define personalized follow-up managements to further prolong patient survival.

Association between D-dimer levels and long-term mortality in patients with aneurysmal subarachnoid hemorrhage.

D-dimer is a marker for hypercoagulability and thrombotic events. The authors sought to investigate whether D-dimer levels predicted long-term mortality in patients with aneurysmal subarachnoid hemorrhage (aSAH). This was a retrospective study of patients with aSAH in West China Hospital, Sichuan University, between December 2013 and June 2019. D-dimer levels were measured within 24 hours after admission and were grouped by quartiles. The primary outcome was long-term mortality. Patient deaths were determined through the Household Registration Administration System in China, with a median of 4.4 years of follow-up. This study included 2056 patients. Compared with patients with the lowest quartile (0.00-0.97 mg/L) of D-dimer levels, the odds of long-term mortality were significantly higher in all other patients, including those with D-dimer levels between 0.97 mg/L and 1.94 mg/L (adjusted hazard ratio [aHR] 1.85, 95% CI 1.32-2.60), those with D-dimer levels between 1.94 mg/L and 4.18 mg/L (aHR 1.94, 95% CI 1.40-2.70), and those patients with the highest quartile (> 4.18 mg/L) of D-dimer levels (aHR 2.35, 95% CI 1.70-3.24; p < 0.001). Similar results were observed for the endpoints of 1-year mortality and long-term mortality in 1-year survivors. Elevated D-dimer levels at admission were associated with short-term and long-term mortality. This biomarker could be considered in future risk nomograms for long-term outcomes and might support future management decisions.

Non-aspirin NSAIDs and head and neck cancer mortality in a Danish nationwide cohort study

BackgroundEvidence suggests that non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs) have antineoplastic properties of potential importance for survival of head and neck cancer. MethodsWe conducted a nationwide cohort study including all individuals with primary head and neck squamous cell carcinoma in Denmark during 2000–2016 at age 30–84 years, with no history of cancer (except non-melanoma skin cancer), and alive at 1 year after diagnosis. Nationwide registries provided information on drug use, causes of death and potential confounders, and additional clinical information was obtained for a subpopulation. We conducted Cox proportional hazards regression to estimate multivariable-adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) for the association between post-diagnosis non-aspirin NSAID use (defined as ≥1 filled prescription within first year after diagnosis) and cancer-specific mortality. ResultsAmong 10,770 head and neck cancer 1-year survivors, the HR for cancer-specific mortality with non-aspirin NSAID use was 1.68 at 1 year after diagnosis, but declined and stabilized around 1.15 (95% CI 1.02–1.29) at 2 years after diagnosis. Among 2-year survivors, the HRs for cancer-specific mortality with non-aspirin NSAID use remained slightly increased in analyses stratified by age, sex, stage, and pre-diagnosis non-aspirin NSAID use. Similar results were seen in the subpopulation (n = 1029) with additional clinical information, and among 5-year survivors with additional non-aspirin NSAID exposure assessment. ConclusionIn this nationwide cohort of patients with head and neck cancer, use of non-aspirin NSAIDs was associated with a slightly increased mortality risk, warranting further evaluation.

Effectiveness, Cost-effectiveness, and Cost-Utility of a Digital Alcohol Moderation Intervention for Cancer Survivors: Health Economic Evaluation and Outcomes of a Pragmatic Randomized Controlled Trial.

BackgroundAlcohol moderation (AM) interventions may contribute to better treatment outcomes and the general well-being of cancer survivors.ObjectiveThis study evaluates the effectiveness, cost-effectiveness, and cost-utility of MyCourse, a digital AM intervention, compared with a noninteractive digital information brochure for cancer survivors.MethodsA health economic evaluation alongside a pragmatic 2-arm parallel-group randomized controlled trial was conducted with follow-ups at 3, 6, and 12 months after randomization. The study was conducted on the web in the Netherlands from 2016 to 2019. Participants were adult 10-year cancer survivors drinking over the Dutch-recommended drinking guidelines (≤7 standard units [10 g of alcohol] per week) with the intention to moderate or quit drinking. Overall, 103 participants were randomized and analyzed: 53 (51.5%) in the MyCourse group and 50 (48.5%) in the control group. In the MyCourse group, participants had access to a newly developed, digital, minimally guided AM intervention, MyCourse–Moderate Drinking. The primary outcome was the self-reported number of standard drinks (10 g of ethanol) consumed in the past 7 days at the 6-month follow-up. The secondary outcome measures were alcohol-related problems as measured by the Alcohol Use Disorders Identification Test (AUDIT) and treatment satisfaction. For the health economic evaluation, health care costs, costs because of productivity losses, and intervention costs were assessed over a 12-month horizon.ResultsAlcohol use at the 6-month follow-up decreased by 38% in the MyCourse group and by 33% in the control group. No difference in 7-day alcohol use was found between the groups (B=2.1, 95% CI −7.6 to 3.1; P=.22) at any of the follow-ups. AUDIT scores for alcohol-related problems decreased over time in both groups, showing no significant difference between the groups (Cohen d=0.3, 95% CI −0.1 to 0.6; P=.21). Intervention costs per participant were estimated at US $279 for the MyCourse group and US $74 for the control group. The mean societal costs were US $18,092 (SD 25,662) and US $23,496 (SD 34,327), respectively. The MyCourse group led to fewer gained quality-adjusted life years at lower societal costs in the cost-utility analysis. In the cost-effectiveness analysis, the MyCourse group led to a larger reduction in drinking units over time at lower societal costs (incremental cost-effectiveness ratio per reduced drink: US $ −1158, 95% CI −1609 to −781).ConclusionsAt 6 months, alcohol use was reduced by approximately one-third in both groups, with no significant differences between the digital intervention MyCourse and a noninteractive web-based brochure. At 12 months, cost-effectiveness analyses showed that MyCourse led to a larger reduction in drinking units over time, at lower societal costs. The MyCourse group led to marginally fewer gained quality-adjusted life years, also at lower societal costs.Trial RegistrationNetherlands Trial Register NTR6010; https://www.trialregister.nl/trial/5433International Registered Report Identifier (IRRID)RR2-10.1186/s12885-018-4206-z

Association Between Radioactive Iodine Treatment for Pediatric and Young Adulthood Differentiated Thyroid Cancer and Risk of Second Primary Malignancies.

PURPOSESince the 1980s, both the incidence of differentiated thyroid cancer (DTC) and use of radioactive iodine (RAI) treatment increased markedly. RAI has been associated with an increased risk of leukemia, but risks of second solid malignancies remain unclear. We aimed to quantify risks of second malignancies associated with RAI treatment for DTC in children and young adults, who are more susceptible than older adults to the late effects of radiation.METHODSUsing nine US SEER cancer registries (1975-2017), we estimated relative risks (RRs) for solid and hematologic malignancies associated with RAI (yes v no or unknown) using Poisson regression among ≥ 5- and ≥ 2-year survivors of nonmetastatic DTC diagnosed before age 45 years, respectively.RESULTSAmong 27,050 ≥ 5-year survivors (median follow-up = 15 years), RAI treatment (45%) was associated with increased risk of solid malignancies (RR = 1.23; 95% CI, 1.11 to 1.37). Risks were increased for uterine cancer (RR = 1.55; 95% CI, 1.03 to 2.32) and nonsignificantly for cancers of the salivary gland (RR = 2.15; 95% CI, 0.91 to 5.08), stomach (RR = 1.61; 95% CI, 0.70 to 3.69), lung (RR = 1.42; 95% CI, 0.97 to 2.08), and female breast (RR = 1.18; 95% CI, 0.99 to 1.40). Risks of total solid and female breast cancer, the most common cancer type, were highest among ≥ 20-year DTC survivors (RRsolid = 1.47; 95% CI, 1.24 to 1.74; RRbreast = 1.46; 95% CI, 1.10 to 1.95). Among 32,171 ≥ 2-year survivors, RAI was associated with increased risk of hematologic malignancies (RR = 1.51; 95% CI, 1.08 to 2.01), including leukemia (RR = 1.92; 95% CI, 1.04 to 3.56). We estimated that 6% of solid and 14% of hematologic malignancies in pediatric and young adult DTC survivors may be attributable to RAI.CONCLUSIONIn addition to leukemia, RAI treatment for childhood and young-adulthood DTC was associated with increased risks of several solid cancers, particularly more than 20 years after exposure, supporting the need for long-term surveillance of these patients.

Childhood leukemia and non-Hodgkin's lymphoma survivors lack knowledge about their past disease and possible late effects. I-BFM ELTEC study with Chilean and Croatian participation.

Late effects in childhood cancer survivors are a major cause of morbidity and mortality. The objective was to establish knowledge about the disease, late effects, self-care practices, application of health knowledge/education, sources of information, and biopsychosocial impact of cancer, and compare the results of Chile and Croatia. One-hundred-and-seventy-one, 5-year survivors who were treated for leukemia or non-Hodgkin's lymphoma responded to a questionnaire (119 in Chile and 52 in Croatia). The questionnaire was reviewed by BFM-ELTEC. Health knowledge about past diagnosis and general treatment had 96% Chilean and 85% Croatian survivors. Ninety percent of Chilean and 73% of Croatian survivors were unaware of possible late effects, and half did not know which specialist to visit for follow-up. Forty-six percent of Chilean and 35% of Croatian survivors knew about healthy lifestyles, but most did not practice them. The 74% of Chileans and 87% of Croatian survivors recalled having received health education during treatment. About 50% of survivors in both groups were afraid or anguish, but it was also a growth experience for 60% of Chilean and 42% of Croatian survivors. Eighty-seven percent Chilean and 77% Croatian survivors considered themselves physically independent, while 76% and 75% felt psychologically independent, respectively. A significant lack of knowledge about the specific treatment, late effects, and future health in both countries was detected. They did not achieve significant learning with the education received. Psychological sequelae were found that are important to prevent.

Importance of long-term surveillance after curative esophagectomy for esophageal squamous cell carcinoma.

The long-term outcomes after esophagectomy for esophageal cancer remain uncertain and the optimal surveillance strategy after curative surgery remains controversial. In this study, the clinicopathological characteristics of patients who underwent curative thoracic esophagectomy between 1991 and 2015 at Toranomon Hospital were retrospectively analyzed and reviewed until December 2020. We evaluated the accumulated data regarding the pattern and rates of recurrence and second malignancy. A total of 1054 patients were eligible for inclusion in the study. Of these, 97% were followed up for 5years, and the outcomes after 25years could be determined in 65.5%. Recurrence was diagnosed in 318 patients (30.2%), and the most common pattern was lymph node metastasis (n = 168, 52.8%). Recurrence was diagnosed within 1year in 174 patients (54.7%) and within 3years in 289 (90.9%). Second malignancy possibly occurred through the entire study period after esophagectomy even in early-stage cancer, keeping 2%-5% of the incidental risk. There was no significant difference in the prognosis between 3-year survivors with and without a second malignancy. Most recurrences after resection of esophageal cancer occurred within 3years regardless of disease stage. However, these patients have an ongoing risk of developing a second malignancy after esophagectomy. Further consideration is required regarding the efficacy of long-term surveillance.

Extracorporeal cardiopulmonary resuscitation for refractory in-hospital cardiac arrest: A retrospective cohort study

BackgroundExtracorporeal cardiopulmonary resuscitation (ECPR) is a rescue therapy for refractory cardiac arrest, but its high mortality has raised questions about patient selection. No selection criteria have been proposed for patients experiencing in-hospital cardiac arrest. We aimed to identify selection criteria available at the time ECPR was considered for patients with in-hospital cardiac arrest. We analyzed data of in-hospital cardiac arrest patients undergoing ECPR in our extracorporeal membrane oxygenation (ECMO) center (March 2007 to March 2019). Intensive care unit (ICU) and 1-year survival post-hospital discharge were assessed. Factors associated with ICU survival before ECPR were investigated. An external validation cohort from a previous multicenter study was used to validate our results. ResultsAmong the 137 patients (67.9% men; median [IQR] age, 54 [43–62] years; low-flow duration, 45 [30–70] min) requiring ECPR, 32.1% were weaned-off ECMO. Their respective ICU- and 1-year survival rates were 21.9% and 19%. Most 1-year survivors had favorable neurological outcomes (cerebral performance category score 1 or 2). ICU survivors compared to nonsurvivors, respectively, were more likely to have a shockable initial rhythm (53.3% versus 24.3%; P < 0.01), a shorter median (IQR) low-flow time (30 (25–53) versus 50 (35–80) min, P < 0.01) and they more frequently underwent a subsequent intervention (63.3% versus 26.2%, P < 0.01). The algorithm obtained by combining age, initial rhythm and low-flow duration discriminated between patient groups with very different survival probabilities in the derivation and validation cohorts. ConclusionSurvival of ECPR-managed in-hospital cardiac arrest patients in this cohort was poor but hospital survivors' 1-year neurological outcomes were favorable. When deciding whether or not to use ECPR, the combination of age, initial rhythm and low-flow duration can improve patient selection.

Profiling of Protein Adducts of Estrogen Quinones in 5-Year Survivors of Breast Cancer Without Recurrence.

AimsThe aim of this study was to simultaneously analyze estrogen quinone-derived adducts, including 17β-estradiol-2,3-quinone (E2-2,3-Q) and 17β-estradiol-3,4-quinone (E2-3,4-Q), in human albumin (Alb) and hemoglobin (Hb) derived from breast cancer patients with five-year postoperative treatment without recurrence in Taiwan and to evaluate the treatment-related effects on the production of these adducts.Settings and DesignCohortMethods and Material: Blood samples derived from breast cancer 5-year survivors without recurrence were collected. Albumin and hemoglobin adducts of E2-3,4-Q and E2-2,3-Q were analyzed to evaluate the degree of disposition of estrogen to quinones and to compare these adduct levels with those in patients before treatment.Statistical AnalysisAll data are expressed as mean ± standard deviation of three determinations. We used Student’s t-test to examine subgroups. Data were transformed to the natural logarithm and tested for normal distribution for parametric analyses. Linear correlations were investigated between individual adduct levels by simple regression. Statistical analysis was performed using the SPSS Statistics 20.0.ResultsResult confirmed that logged levels of E2-2,3-Q-derived adducts correlated significantly with those of E2-3,4-Q-derived adducts (correlation coefficient r=.336-.624). Mean levels of E2-2,3-Q-4-S-Alb and E2-3,4-Q-2-S-Alb in 5-year survivors were reduced by 60-70% when compared to those in the breast cancer patients with less than one year of diagnosis/preoperative treatment (P<.001).ConclusionsOur findings add support to the theme that hormonal therapy including aromatase inhibitors and Tamoxifen may dramatically reduce burden of estrogen quinones. We hypothesize that combination of treatment-related effects and environmental factors may modulate estrogen homeostasis and diminish the production of estrogen quinones in breast cancer patients.
