The Impact

ObjectiveClinical outcomes for patients with uterine carcinosarcoma are poor after surgical management alone. Adjuvant therapies including chemotherapy (CT) and/or radiation therapy (RT) have been previously investigated, but the optimal management of this disease remains controversial. The purposes of this study were to analyze the patterns of use of adjuvant CT and RT and to assess the impact on survival of each of these treatment regimens using the National Cancer Data Base.Methods/MaterialsThe National Cancer Data Base was queried for patients given a diagnosis of uterine carcinosarcoma confined to the pelvis who underwent total hysterectomy/bilateral salpingo-oophorectomy between 2004 and 2011. Patients were excluded if they survived less than 4 months after diagnosis. Data regarding CT and RT use were collected. Overall survival (OS) was analyzed using the Kaplan-Meier method. Multivariable Cox regression analysis was performed to evaluate the effect of covariates on OS.ResultsA total of 4906 patients were included in this study. Median age was 67 years (interquartile range, 60–75 years). Median follow-up was 28.9 months (interquartile range, 15.4–52.9 months). There were 1777 patients (36.2%) who received no adjuvant treatment, 971 (19.8%) who received CT alone, 1060 (21.6%) who received RT alone, and 1098 (22.4%) who received both RT and CT. The 5-year OS for patients receiving no adjuvant therapy, adjuvant RT alone, adjuvant CT alone, and combined CT and RT were 44.9%, 47.1%, 47.5%, and 62.9%, respectively. On pairwise analysis, combined CT and RT was associated with improved survival compared with all other subgroups (P < 0.001). On multivariable Cox regression analysis, combined CT and RT (hazard ratio, 0.50; 95% confidence interval, 0.44–0.57; P < 0.001) and CT alone (hazard ratio, 0.78; 95% confidence interval, 0.69–0.88; P < 0.001) were significantly associated with improved OS, whereas RT alone was not.ConclusionsCombination therapy with CT and RT was associated with significantly improved 5-year OS compared with no further therapy, RT alone, or CT alone.

79 Background: There are conflicting reports on the value of the extent of post neoadjuvant chemoradiation (NCRT) lymphadenectomy (LND) in locally advanced esophageal adenocarcinoma (E-ADC) and squamous cell carcinoma (E-SCC). We sought to study the impact of LND variables [positive and total lymph node (LN) number and LN ratio (LNR)] on oncological outcomes in these patients. Methods: The National Cancer Data Base 2004-2014 was queried for patients with NCRT followed by esophagectomy. The median examined LN number was used to divide the patients into a higher (> 12) and lower (≤ 12) LND groups. The primary outcome was overall survival (OS) and secondary outcomes were 30- and 90-day postoperative mortality. Results: A total 4708 patients were included. The median of positive, negative LN, and LNR were and (0, 11, 0%). The median and 5-year OS for higher LND group were higher than the lower LND group (39 vs. 32 months, 38% vs. 34%), p < 0.0001. OS was not significantly different among E-SCC subset or among those who achieved pathological complete response (pCR). The higher LND group had better 30- and 90-day postoperative mortality rates (61/2335 = 2.6%, 141/2308 = 6.1%) than lower LND group (86/2262 = 3.8%, 184/2251 = 8.2%), p = 0.01 and 0.001, respectively . In multivariate Cox regression analysis, higher LND group (HR 0.88, 95% CI 0.81-0.96, p = 0.004) and LNR (per 10% increase: 1.11, 95% CI 1.09-1.13, p < 0.0001) were significant predictor of OS. Conclusions: The LND (> 12 examined LN) remains as a crucial treatment goal after NCRT with potential survival benefit, especially among E-ADC and those did not achieve pCR.

Nlrp3 Expression

Abstract Background: Lung adenocarcinoma (LUAD) and skin cutaneous melanoma (SKCM) are common tumors around the world. However, the prognosis in advanced patients is poor. Because NLRP3 was not extensively studied in cancers, so that we aimed to identify the impact of NLRP3 on LUAD and SKCM through bioinformatics analyses. Methods: TCGA and TIMER database were utilized in this study. We compared the expression of NLRP3 in different cancers and evaluated its influence on survival of LUAD and SKCM patients. The correlations between clinical information and NLRP3 expression were analyzed using logistic regression. Clinicopathologic characteristics associated with overall survival in were analyzed by Cox regression. In addition, we explored the correlation between NLRP3 and immune infiltrates. GSEA and co-expressed gene with NLRP3 were also done in this study. Results: NLRP3 expressed disparately in tumor tissues and normal tissues. Cox regression analysis indicated that up-regulated NLRP3 was an independent prognostic factor for good prognosis in LUAD and SKCM. Logistic regression analysis showed increased NLRP3 expression was significantly correlated with favorable clinicopathologic parameters such as no lymph node invasion and no distant metastasis. Specifically, a positive correlation between increased NLRP3 expression and immune infiltrating level of various immune cells was observed. Conclusion: Together with all these findings, increased NLRP3 expression correlates with favorable prognosis and increased proportion of immune cells in LUAD and SKCM. These conclusions indicate that NLRP3 can serve as a potential biomarker for evaluating prognosis and immune infiltration level.

The Impact

Objective: The impact of increased C-reactive protein (CRP)/albumin ratio on intra-hospital mortality has been investigated among patients admitted to general intensive care units (ICU). However, it was not investigated among patients with spontaneous intracerebral hemorrhage (ICH). This study aimed to investigate the impact of CRP/albumin ratio on intra-hospital mortality in patients with ICH. Patients and Methods: This retrospective study was conducted on 379 ICH patients admitted between 02/2008 and 12/2017. Blood samples were drawn upon admission and the patients’ demographic, medical, and radiological data were collected. The identification of the independent prognostic factors for intra-hospital mortality was calculated using binary logistic regression and COX regression analysis. Results: Multivariate regression analysis shows that higher CRP/albumin ratio (odds ratio (OR) = 1.66, 95% confidence interval (CI) = 1.193–2.317, p = 0.003) upon admission is an independent predictor of intra-hospital mortality. Multivariate Cox regression analysis indicated that an increase of 1 in the CRP/albumin ratio was associated with a 15.3% increase in the risk of intra-hospital mortality (hazard ratio = 1.153, 95% CI = 1.005–1.322, p = 0.42). Furthermore, a CRP/albumin ratio cut-off value greater than 1.22 was associated with increased intra-hospital mortality (Youden’s Index = 0.19, sensitivity = 28.8, specificity = 89.9, p = 0.007). Conclusions: A CRP/albumin ratio greater than 1.22 upon admission was significantly associated with intra-hospital mortality in the ICH patients.

Retrospective Multicenter Study

The efficacy of hemoperfusion (HP) in patients with acute paraquat poisoning (PQ) remains controversial. We conducted a multi-center retrospective study to include acute PQ-poisoned patients admitted to two tertiary medical centers between 2005 and 2015. We used the Severity Index of Paraquat Poisoning (SIPP) to stratify the severity of PQ-poisoned patients. The indication to start HP was a positive result for the semiquantitative urine PQ test and presentation to the hospital was within 24 h. Early HP was defined as the first session of HP performed within five hours of PQ ingestion. A total of 213 patients (100 HP group, 113 non-HP group) were eligible for the study. The overall 60-day mortality of poisoned patients was 75.6% (161/213). Multivariate Cox regression analysis showed no statistically significant difference in 60-day survival between HP and non-HP groups (95% confidence interval (CI): 0.84–1.63, p = 0.363). Further subgroup analysis in the HP group showed early HP (95% CI: 0.54–1.69, p = 0.880), and multiple secessions of HP (95% CI: 0.56–1.07, p = 0.124) were not significantly related to better survival. Among acute PQ-poisoned patients, this study found that HP was not associated with increased 60-day survival. Furthermore, neither early HP nor multiple secessions of HP were associated with survival.

e19022 Background: There has been some improvement in overall survival (OS) for patients with MCL over the past years [Gordon 2014]. However, side effects of treatment remain a major concern. With introduction of novel therapies like IT, it is imperative to optimize treatment regimens to improve survival while minimizing toxicity. Methods: MCL patients (pts) who were diagnosed in 2013 or later with information available about chemotherapy (CT) and IT and did not receive transplant were extracted from NCDB. Pts were assigned to age categories and were sorted into six groups based on different combinations of CT (none, single agent (SA), and multi-agent (MA)) with or without IT. Cox regression analysis was used to perform multivariate analysis that included age category, sex, race, clinical stage, Charlson/Deyo score, CT, radiation, and IT for each group. Multivariate p values (p) were used to analyze statistical significance. Kaplan Meier method was utilized to analyze OS. T-test was used to compare means (t-p). Results: 1438 total pts were identified with a mean age of 70 (range 24-90); 71% male; 93% white, 4% black, 3% others; 42% with stage III/IV disease. 667 pts did not receive CT or IT, and 40 received IT alone and both of these groups were excluded from further analysis. 52 pts received SA- (without) IT, 206 received SA+(with) IT and 260 pts received MA-IT and 213 MA+IT. Mean age was 72 and 66 for SA and MA groups, respectively (t-p<0.01). Mean OS for SA+IT was 27 months (m) vs SA-IT 16 m (p < 0.01). MA+IT v MA-IT showed no difference in mean OS (25 vs 26 m, respectively, p =0.49). Although there was a significant difference in OS between SA and MA groups without IT (16 vs 25 months, p < 0.01). SA + IT group showed comparable mean OS time to MA + IT (27 vs 26 m, p =0.145). Conclusions: For MCL pts, MA has superior OS to SA group. However, adding IT significantly improves OS for SA group and makes it comparable to MA. Adding IT to MA did not provide significant difference in OS. These results highlight the possibility of achieving same OS with less toxic regimens. Hence further evaluation in a prospective study to optimize treatment while reducing toxicity is warranted.

2 Background: The association of the interval between neoadjuvant chemo-radiation and surgery (CRT-S), and cancer outcomes in patients with esophageal cancer is not clear. We aimed to determine the relationship between CRT-S interval and pathological complete response rate (pCR), short and long overall survival (OS). Methods: Patients listed on the National Cancer Data Base from 2004 to 2013 were studied. We included patients with CRT followed by surgery in 15-90 days. All patients had reported pT, pN cancer stages and survival status. CRT-S interval was studied as continuous (weeks) and categorical variables (quintiles). Results: A total of 5181 patients were included; 81% were adenocarcinomas, 84% were males and mean age was 62 years. They were divided into CRT-S interval quintiles (15 to 37, 38 to 45, 46 to 53, 54 to 64 and 65 to 90 days) (n = 1016, 1063, 1081, 1083 and 938 patients), respectively. There was a significant increase of pCR rate across the CRT-S quintiles (18%, 21%, 24%, 25% and 29%, p < 0.001). This advantage persisted when CRT-S was measured as continuous variable in weeks (OR: 1.11, 95% CI = 1.078-1.143, p < 0.001). However, 90-day mortality significantly increased as CRT-S increased across quintiles (5.7%, 6.2%, 6.8%, 8.5% and 8.2%, p = 0.02) and through weeks (OR = 1.05, 95%CI = 1.005-1.106, p = 0.03). Mean OS across CRT-S quintiles was 59.2, 58.8, 55.4, 56.6 and 51.5 months, respectively. Multivariate Cox regression showed significantly worse OS per week increase in CRT-S interval (HR 1.02, 95% 1.003-1.037, p = 0.02), especially among the last quintile (CRT-S = 65-90 days: HR 1.2, 95% CI 1.04-1.32, p = 0.009). Those with no-pCR had worse OS as time to surgery increased (p < 0.001), while pCR group had similar OS across CTR-S intervals. Conclusions: Despite higher pCR rate as CRT-S interval increasing, surgery is preferred to be done in less than 65 days after CRT to avoid worse 90-day mortality and achieve better OS. Further randomized studies are needed to consolidate our findings.

Carcinoma Of The Bladder

Purpose Evidence from studies of other malignancies has indicated that aggressive local treatment (LT), even in the presence of metastatic disease, is beneficial. Against a backdrop of stagnant mortality rates for metastatic urothelial carcinoma of the bladder (mUCB) at presentation, we hypothesized that high-intensity LT of primary tumor burden, defined as the receipt of radical cystectomy or ≥ 50 Gy of radiation therapy delivered to the bladder, affects overall survival (OS). Patients and Methods We identified 3,753 patients within the National Cancer Data Base who received multiagent systemic chemotherapy combined with high-intensity versus conservative LT for primary mUCB. Patients who received no LT, transurethral resection of the bladder tumor alone, or < 50 Gy of radiation therapy delivered to the bladder were included in the conservative LT group. Inverse probability of treatment weighting (IPTW) –adjusted Kaplan-Meier curves and Cox regression analyses were used to compare OS of patients who received high-intensity versus conservative LT. Results Overall, 297 (7.91%) and 3,456 (92.09%) patients with mUCB received high-intensity and conservative LT, respectively. IPTW-adjusted Kaplan-Meier curves showed that median OS was significantly longer in the high-intensity LT group than in the conservative LT group (14.92 [interquartile range, 9.82 to 30.72] v 9.95 [interquartile range, 5.29 to 17.08] months, respectively; P < .001). Furthermore, in IPTW-adjusted Cox regression analysis, high-intensity LT was associated with a significant OS benefit (hazard ratio, 0.56; 95% CI, 0.48 to 0.65; P < .001). Conclusion We report an OS benefit for individuals with mUCB treated with high-intensity versus conservative LT. Although the findings are subject to the usual biases related to the observational study design, these preliminary data warrant further consideration in randomized controlled trials, particularly given the poor prognosis associated with mUCB.
