The Impact

Renal insufficiency (RI) is commonly seen in patients with hepatocellular carcinoma (HCC). The prognostic role of albumin-bilirubin (ALBI) grade in this special setting is unclear. We aimed to investigate the role of ALBI grade associated with the impact of RI on HCC. A prospective cohort of 3690 HCC patients between 2002 and 2016 were retrospectively analyzed. The Kaplan–Meier method and multivariate Cox proportional hazards model were used to determine survival and independent prognostic predictors. Of all patients, RI was an independent predictor associated with decreased survival. In multivariate Cox analysis for patients with RI, α-fetoprotein level ≥20 ng/mL, tumor size >3 cm, vascular invasion, distant metastasis, presence of ascites, performance status 1–2, performance status 3–4, and ALBI grade 2 and grade 3 were independent predictors of decreased survival (all p < 0.05). In subgroup analysis of patients with RI undergoing curative and non-curative treatments, the ALBI grade remained a significant prognostic predictor associated with decreased survival (p < 0.001). In summary, HCC patients with RI have decreased survival compared to those without RI. The ALBI grade can discriminate the survival in patients with RI independent of treatment strategy and is a feasible prognostic tool in this special patient population.

Poor Prognostic Factor

e15754 Background: Elevated pre-treatment NLR is a well-known poor prognostic factor in several tumours, including aPC. However, the role of NLR changes during first-line chemotherapy is less investigated. Methods: We retrospectively evaluated aPC patients (pts) treated with FOLFOXIRI (infusional 5-fluorouracil, oxaliplatin, irinotecan). NLR was calculated before the first (NLR-0) and the fourth (NLR-3) cycle, high NLR being defined as > 4. We evaluated the correlation between NLR change and overall survival (OS), progression-free survival (PFS), response rate (RR) and disease-control-rate (DCR). Survival curves were estimated using the Kaplan-Meier method. Log-rank and chi-square tests were applied. Multivariate analysis was performed by Cox proportional hazards model. Results: Ninety-four pts were evaluable. Median age was 62 years; at diagnosis, 38 (40.4%) pts had unresectable stage III and 56 (59.6%) had stage IV disease. In the overall population, median PFS (mPFS) and OS (mOS) were 8.0 and 12.9 months, respectively. NLR-0 was significantly associated with poor prognosis: among the 12 pts with NLR-0 > 4 mOS was 5.1 months compared with 13.5 months for the 82 pts with NLR-0 ≤4 (p < 0.001). As regards NLR dynamics, NLR-3 remained high or was increased (H/I) in 5 pts (5.3%) while was stably low or decreased (L/D) in 89 pts (94.7%). mOS was 5.1 months (95%CI 0.4-9.8) in H/I and 13.5 months (95%CI 10.9-16.1) in L/D (p < 0.001) pts. The same association was found for PFS, with 4.7 (95%CI 2.1-7.3) vs 8.3 months (95%CI 6.2-10.4, p = 0.004), respectively, but not for RR and DCR. At multivariate analysis, NLR change was confirmed as independent predictor of OS (HR 6.854, 95%CI 2.109-22.269, p = 0.001) and, when added to performance status, liver metastases and NLR-0, allowed a better risk stratification in good (no negative factors), intermediate (1-2 factors) and poor (3-4 factors) risk groups, with mOS of 18.0, 10.0 and 5.1 months, respectively (p = 0.012). Conclusions: Not only NLR-0, but also changes after 3 cycles of first-line FOLFOXIRI could predict OS in aPC pts. Early variations in NLR might be a cheap, reproducible and useful factor to predict prognosis and to better refine treatment strategy.

Age At Exposure

Abstract. Background: We investigated the age at exposure to parental suicide and the risk of subsequent suicide completion in young people. The impact of parental and offspring sex was also examined. Method: Using a cohort study design, we linked Taiwan's Birth Registry (1978–1997) with Taiwan's Death Registry (1985–2009) and identified 40,249 children who had experienced maternal suicide (n = 14,431), paternal suicide (n = 26,887), or the suicide of both parents (n = 281). Each exposed child was matched to 10 children of the same sex and birth year whose parents were still alive. This yielded a total of 398,081 children for our non-exposed cohort. A Cox proportional hazards model was used to compare the suicide risk of the exposed and non-exposed groups. Results: Compared with the non-exposed group, offspring who were exposed to parental suicide were 3.91 times (95% confidence interval [CI] = 3.10–4.92 more likely to die by suicide after adjusting for baseline characteristics. The risk of suicide seemed to be lower in older male offspring (HR = 3.94, 95% CI = 2.57–6.06), but higher in older female offspring (HR = 5.30, 95% CI = 3.05–9.22). Stratified analyses based on parental sex revealed similar patterns as the combined analysis. Limitations: As only register-­based data were used, we were not able to explore the impact of variables not contained in the data set, such as the role of mental illness. Conclusion: Our findings suggest a prominent elevation in the risk of suicide among offspring who lost their parents to suicide. The risk elevation differed according to the sex of the afflicted offspring as well as to their age at exposure.

Supratotal Resection

Objective Extent of resection (EOR) and Karnofsky Performance Status (KPS) are at odds in glioblastoma (GBM) surgery, that is, the anticipated postoperative disability limits the EOR. This study analyzes the correlation of different surgical modalities with the resulting physical status and survival of patients with GBM. Methods A total of 565 patients with primary GBM were operated on in a single institution between 2006 and 2014. Possible surgical modalities comprised supratotal resection (SLR), gross total resection (GTR; ≥ 95% by volume), tumor debulking (TDB; ≤ 95% by volume), and stereotactic biopsy (SB). Pre- and postoperative KPS before and up to 4 weeks after surgery as well as overall survival (OS) rate were determined retrospectively. Hazard ratio (HR) and 95% confidence intervals were calculated using a Cox proportional hazards model. Results Median postoperative KPS was ≥ 70, irrespective of surgical modality. Mean OS was 12.5 months. Multivariate analysis revealed age ≥ 70 years (HR: 1.93), preoperative KPS < 70 (HR: 2.15), and unmethylation in MGMT promoter (HR: 1.27) as independent factors for worse OS. Regarding surgical modality, SB was associated with the worst survival (HR: 2.3) followed by TDB (HR: 1.36). SLR was inferior to GTR (HR: 1.27). Conclusion Higher EOR in patients with GBM does not seem inevitably correlated with increasing functional impairment, but better survival, provided there is a balanced preoperative indication. Nevertheless, SLR does not seem to be superior to GTR. Whenever possible, maximal safe resection should be considered in patients with GBM, even if an EOR ≥ 95% is not possible.

The Impact

Abstract The U.S. Supreme Court’s decision to grant states the authority to reject Medicaid expansion under the Affordable Care Act without penalty threatened the implementation of this polarized health policy. While many Republican-controlled states followed their national allies and rejected Medicaid expansion, others engaged in bipartisan implementation. Why were some Republican states willing to reject the national partisan agenda and cooperate with Democrats in Washington? I focus on the role of electoral competition within states. I conclude that although electoral competition has been shown to encourage partisan polarization within the states, the combination of intergovernmental implementation and Medicaid expansion’s association with public welfare reverses this dynamic. I employ a Cox proportional-hazards model to examine the impact of state partisan ideology and competition on the likelihood of state Medicaid expansion. I find that strong inter-party competition mitigates the impact of more extreme partisan ideologies, encouraging potentially bipartisan negotiation with the federal administration.

Abstract In this paper, the liquidity (inverse of time on market) of rental dwellings and its determinants for different liquidity quantiles are examined for the seven largest German cities. The determinants are estimated using censored quantile regressions in order to investigate the impact on very liquid to very illiquid dwellings. As market heterogeneity is not only observed between cities but also within a city, each of the seven cities is considered individually. Micro data for almost 500,000 observations from 2013 to 2017 is used to examine the time on market. Substantial differences in the magnitude and direction of the regression coefficients for the different liquidity quantiles are found. Furthermore, both the magnitude and direction of the impact of an explanatory variable on the liquidity, differ between the cities. To the best of the authors’ knowledge this is the first paper, to apply censored quantile regressions to liquidity analysis of the real estate rental market. The model reveals that the proportionality assumption underlying the Cox proportional hazards model cannot be confirmed for all variables across all cities, but for most of them.

BackgroundWe performed a review of a large incident peritoneal dialysis cohort to establish the impact of current practice and that of switching to hemodialysis.MethodsPatients starting peritoneal dialysis between 2004 and 2010 were included and clinical data at start of dialysis recorded. Competing risk analysis and Cox proportional hazards model with time-varying covariate (technique failure) were used.ResultsOf 286 patients (median age 57 years) followed for a median of 24.2 months, 76 were transplanted and 102 died. Outcome probabilities at 3 and 5 years respectively were 0.69 and 0.53 for patient survival (or transplantation) and 0.33 and 0.42 for technique failure. Peritonitis caused technique failure in 42%, but ultrafiltration failure accounted only for 6.3%. Davies comorbidity grade, creatinine and obesity (but not residual renal function or age) predicted technique failure. Due to peritonitis deaths, technique failure was an independent predictor of death hazard. When successful switch to hemodialysis (surviving more than 60 days after technique failure) and its timing were analyzed, no adverse impact on survival in adjusted analysis was found. However, hemodialysis via central venous line was associated with an elevated death hazard as compared to staying on peritoneal dialysis, or hemodialysis through a fistula (adjusted analysis hazard ratio 1.97 (1.02 – 3.80)).ConclusionsOnce the patients survive the first 60 days after technique failure, the switch to hemodialysis does not adversely affect patient outcomes. The nature of vascular access has a significant impact on outcome after peritoneal dialysis failure.

e19268 Background: Prior studies have demonstrated that clonal cells that give rise to pancreatic peritoneal metastases (PM) are geographically and genetically distinct from clonal cells, giving rise to lung and liver metastases. The objective of this study was to assess if there is a distinct difference in prognosis and therapeutic response among patients with pancreatic cancer with (PM compared to the lung/liver. Methods: Using a retrospective cohort design, medical records from adult patients diagnosed with metastatic adenocarcinoma of the pancreas at five Canadian academic cancer centers (2014 - 2019) were reviewed. Prognostic variables including age, Charlson comorbidity index, ECOG, cigarette smoking, nodal status, sites of metastases, and first line chemotherapy were collected. Cox proportional hazards model (MVA) was used to examine the association between peritoneal involvement and survival, adjusted for measured confounders. Analyses were completed using SAS, where alpha of 0.05 was defined as the level of significance. Results: A total of 1161 patients were included. Metastatic sites included peritoneum (n = 170, 14.6%), lung (n = 145, 12.5%) and liver (n = 563, 48.5%). Patients with PM received first-line FOLFIRINOX (FFX, n = 31), Gemcitabine + nab-paclitaxel (G/N, n = 20), Gemcitabine (G, n = 18), and no treatment (n = 97). In univariate analyses, worse ECOG PS was associated with PM (p = 0.002). The majority of patients died (89%), with a median overall survival (OS) of 3 vs 7 months for patients with PM and those without PM (p < 0.001), respectively. The median OS in patient whom receive first-line chemotherapy was 7 months in FFX group (95% CI 1.66-12.33), 6 months in G/N (95% CI 4.54-7.45) and 2 months in G group (95% CI 1.42-2.57). Patients had significantly better OS when treated with FFX or G/N compared to G alone (p = 0.002). Time to treatment failure was significantly shorter among patient treated with G alone compare to patients treated with FFX and G/N (P < 0.005). Conclusions: In the setting of combination chemotherapy for advanced pancreatic cancer, patients with PM continue to have a poor prognosis. This may be due to the impact of PM on PS and the inability to administer palliative chemotherapy. For eligible patients, FFX or G/N results in a higher OS than G monotherapy.

ObjectiveThe objectives of this study were to evaluate the rates of chemotherapy and radiotherapy delivery in the treatment of uterine serous carcinoma in the Medicare population and to compare clinical outcomes in treated and untreated patients.MethodsThe linked Surveillance, Epidemiology, and End Results and Medicare databases were queried to identify patients with a diagnosis of uterine serous carcinoma between 1992 and 2009. The impact of chemotherapy on survival was analyzed using the Kaplan-Meier method. Factors predictive of outcome were compared using the Cox proportional hazards model.ResultsA total of 2188 patients met study eligibility criteria. Stages I, II, III, and IV diseases accounted for 890 (41%), 174 (8%), 470 (21%), and 654 (30%) of the study population, respectively. Chemotherapy, radiotherapy, both, or none, were administered as adjuvant therapy in 635 (29%), 536 (24%), 308 (14%), and 709 (32%) of the study population, respectively. Use of chemotherapy became more frequent over time. Over the study period, and after adjusting for race, time of diagnosis, SEER registry, marital status, stage, age, surgery, lymph node dissection, socioeconomic status, and comorbidity index, there was an association between receipt of radiotherapy alone (hazard ratio [HR], 1.3; 95% CI, 1.04–1.67) and not receiving any treatment (HR, 1.5; 95% CI, 1.2–2.01) and worst survival. Survival was not improved over time.ConclusionAlthough adjuvant chemotherapy and combination treatment with chemotherapy and radiation were associated with improved survival in our model, there was no significant improvement in survival over time.

The Impact

Previous studies have shown that more frequent social participation was associated with a reduced risk of mortality. However, limited studies have explored the changes in the frequency of social participation in older adults. We investigated the impact of the changes in the frequency of social participation on all-cause mortality in Japanese older adults aged 60 years and older. The current study, conducted as a secondary analysis, was a retrospective cohort study using open available data. The participants were 2240 older adults (45.4% male and 54.6% female) sampled nationwide from Japan who responded to the interview survey. Changes in the frequency of social participation were categorized into four groups (none, initiated, decreased, and continued pattern) based on the responses in the baseline and last surveys. The Cox proportional-hazards model showed a decreased risk of all-cause mortality in decreased and continued patterns of social participation. Stratified analysis by sex showed a decreased risk of mortality in the continued pattern only among males. The results of the current study suggest that the initiation of social participation at an earlier phase of life transition, such as retirement, may be beneficial for individuals.
