Abstract Background and objectives The purpose of the present study was to comprehensively analyze the prognostic value of adjuvant chemotherapy (CT) in stage IV HCC patients. Methods HCC patients were recognized in the Surveillance, Epidemiology and End Results (SEER) database. The effects of adjuvant CT on HCC patients were evaluated by Kaplan–Meier curves and multivariable Cox proportional hazards analyses. Results A total of 490 HCC patients were enrolled in this study and the median follow-up time was 2.69 months (range: 0–102 months). 34.3% (168) HCC patients received adjuvant CT, of which 58.6% (287) received local destruction, 25.5% (125) were partial resection and 15.9% (78) underwent liver transplantion. Multivariate analysis showed that chemotherapy (P <0.001), surgery (P <0.001), year at diagnosis (P = 0.004), grade (P <0.001) and fibrosis score (P = 0.039) were independent factor of cancer specific survival (CSS), and that chemotherapy (P <0.001), surgery (P <0.001), year at diagnosis (P = 0.005), grade (P <0.001) were independent factor of overall survival (OS). Survival curves confirmed that patients achieved an increased OS or CSS from adjuvant CT (P <0.05). Conclusions Our results concluded that compared to surgery alone, stage IV HCC patients could profit from adjuvant chemotherapy. High quality prospective trials are necessary to further confirm our results.

Abstract Background The role of cardiovascular implantable electronic device (CIED)-derived activity to predict inappropriate implantable cardioverter-defibrillator (ICD) therapy is not known. The Multicenter Automatic Defibrillator Implantation Trial – Reduce Inappropriate Therapy (MADIT-RIT) enrolled 1500 patients with contemporary indication for an ICD or a CRT-D. We aimed to identify whether activity, as a digital biomarker, predicted inappropriate therapy. Methods In 1500 patients enrolled in MADIT-RIT, CIED-derived patient activity was acquired daily. CIED-derived activity was averaged for the first 30 days following randomization and utilized in this study to predict inappropriate therapy post- 30-day. Kaplan-Meier survival analysis and multivariate Cox proportional hazards regression models were used to evaluate first inappropriate therapy by 30-day CIED-derived patient activity quintiles, and by 30-day device derived patient activity as a continuous measurement. Results There were a total of 1463 patients with activity data available (90%), 135 patients received at least one inappropriate therapy during the post-30 day follow-up period. Patients in the highest quintile (Q5) of CIED-derived activity (more active) were younger, more often males and more likely to have had a prior ablation of an atrial arrhythmia. Patients in the highest quintile of 30-day CIED-derived median activity had the highest risk of receiving inappropriate therapy, 21% at 2 years as compared 7–11% in the other four quintiles (Figure, p<0.001 for the overall duration). Patients with the highest level of 30-day median patient activity (Q5) had 1.75 times higher risk of any inappropriate therapy as compared with lower levels of activity, Q1-Q4 (HR=1.75, 95% CI: 1.23–2.50, p<0.002). Each 10% increase in CIED-derived 30-day median patient activity was associated with a significant, 73% increase in risk of receiving inappropriate therapy (HR=1.73, 95% CI: 1.17–2.54, p=0.005). Patients in the highest quintile for activity had a 68% increase in the risk of SVT excluding atrial fibrillation, atrial flutter or atrial tachycardia (HR=1.69, 95% CI: 1.26–2.25, p=0.004), despite 96% receiving beta-blocker medications. Inappropriate ICD Therapies by Activity Conclusions CIED-derived 30-day median patient activity predicted subsequent inappropriate therapy in ICD and CRT-D patients enrolled in MADIT-RIT. Patients with high levels of 30-day CIED-derived median patient activity were at a significantly higher risk of receiving inappropriate therapy. Activity, as a digital biomarker, may have utility in predicting and managing the risk of inappropriate therapy in this population. Acknowledgement/Funding Boston Scientific

Abstract Aim: This National Cancer Database (NCDB) analysis was performed to evaluate the outcomes of adjuvant chemotherapy (AC) versus observation for resected pancreatic adenocarcinoma treated with neoadjuvant therapy (NT). Materials and methods: The NCDB was queried for primary stages I–II cT1-3N0-1M0 resected pancreatic adenocarcinoma treated with NT (2004–2015). Baseline patient, tumour and treatment characteristics were extracted. The primary end point was overall survival (OS). With a 6-month conditional landmark, Kaplan–Meier analysis, multivariable Cox proportional hazards method and 1:1 propensity score matching was used to analyse the data. Results: A total of 1,737 eligible patients were identified, of which 1,247 underwent post-operative observation compared to 490 with AC. The overall median follow-up was 34·7 months. The addition of AC showed improved survival on the multivariate analysis (HR 0·78, p < 0·001). AC remained statistically significant for improved OS, with a median OS of 26·3 months versus 22·3 months and 2-year OS of 63·9% versus 52·9% for the observation cohort (p < 0·001). Treatment interaction analysis showed OS benefit of AC for patients with smaller tumours. Findings: Our findings suggest a survival benefit for AC compared to observation following NT and surgery for resectable pancreatic adenocarcinoma, especially in patients with smaller tumours.

IntroductionThe role of lymphadenectomy in the management of uterine leiomyosarcoma (LMS) is controversial. We aimed to identify whether lymph node dissection (LND) has any survival benefit in uterine LMS.MethodsData of 95 patients with histologically proven uterine LMS from 2 tertiary centers (1993 through 2009) were retrospectively analyzed. Kaplan-Meier and Cox proportional hazards regression models were used for analyses.ResultsMean age was 51.5 years. Thirty-six (37.9%) underwent LND. The median lymph node count was 54. Eight (22.2%) patients had lymphatic metastasis. Median follow-up was 26 months. Sixty-two (65%) patients had recurrence and 48 (50.5%) died. Median disease-free survival (DFS) was 19 months for both group of patients who had or did not have LND, and median overall survival (OS) was 29 and 26 months, respectively (P= 0.4). Five-year DFS was 35.9% vs 26.8% (P= 0.4), and 5-year OS was 45.4% vs 43.8% (P= 0.22) for the groups. Multivariate analyses did not reveal a single independent prognostic factor in respect to DFS or OS.ConclusionHigher rate of lymph node metastasis in patients with extrauterine disease indicated the importance of LND in LMS. However, the survival benefit of lymphadenectomy could not be shown.

The Impact

Data supporting the use of etoposide-based therapy in hemophagocytic lymphohistiocytosis (HLH) arise largely from pediatric studies. There is a lack of comparable data among adult patients with secondary HLH. We conducted a retrospective study to assess the impact of etoposide-based therapy on outcomes in adult secondary HLH. The primary outcome was overall survival. The log-rank test was used to compare Kaplan-Meier distributions of time-to-event outcomes. Multivariable Cox proportional hazards modeling was used to estimate adjusted hazard ratios (HRs) with 95% confidence intervals (CIs). Ninety adults with secondary HLH seen between January 1, 2009, and January 6, 2020, were included. Forty-two patients (47%) received etoposide-based therapy, while 48 (53%) received treatment only for their inciting proinflammatory condition. Thirty-three patients in the etoposide group (72%) and 32 in the no-etoposide group (67%) died during follow-up. Median survival in the etoposide and no-etoposide groups was 1.04 and 1.39 months, respectively. There was no significant difference in survival between the etoposide and no-etoposide groups (log-rank <i>p</i> = 0.4146). On multivariable analysis, there was no association between treatment with etoposide and survival (HR for death with etoposide = 1.067, 95% CI: 0.633–1.799, <i>p</i> = 0.8084). Use of etoposide-based therapy was not associated with improvement in outcomes in this large cohort of adult secondary HLH patients.

Evidence on the role of supper timing in the development of cardiovascular disease (CVD) is limited. In this study, we examined the associations between supper timing and risks of mortality from stroke, coronary heart disease (CHD), and total CVD. A total of 28,625 males and 43,213 females, aged 40 to 79 years, free from CVD and cancers at baseline were involved in this study. Participants were divided into three groups: the early supper group (before 8:00 p.m.), the irregular supper group (time irregular), and the late supper group (after 8:00 p.m.). Cox proportional hazards regression models were used to calculate hazard ratios (HRs) for stroke, CHD, and total CVD according to the supper time groups. During the 19-year follow-up, we identified 4706 deaths from total CVD. Compared with the early supper group, the multivariable HR of hemorrhagic stroke mortality for the irregular supper group was 1.44 (95% confidence interval [CI]: 1.05–1.97). There was no significant association between supper timing and the risk of mortality from other types of stroke, CHD, and CVD. We found that adopting an irregular supper timing compared with having dinner before 8:00 p.m. was associated with an increased risk of hemorrhagic stroke mortality.

Introduction: There have been few studies evaluating the influence of time to wound healing on outcomes in patients with critical limb ischemia (CLI) after endovascular therapy. Methods: In this prospective study, patients with CLI treated with endovascular therapy were assessed for comorbidities, presence of wounds, wound healing, and major adverse limb events (MALE; major amputation, surgical endartectomy, or bypass) over time. The incidence of MALE was compared across patient and wound characteristics by Kaplan-Meier analysis. Associations between these variables and MALE were determined by Cox proportional hazards analysis. Results: A total of 252 consecutive patients with CLI were treated between November 1, 2011 and April 1, 2015; 179 (71%) had wounds, of which 97 (54%) healed. During median follow-up of 12.7 months (interquartile range 3.9 - 23.9 months), 46 (18%) had MALE. Wounds were associated with a greater risk of MALE (Hazard Ratio [HR] 3.5; 95% Confidence Interval [CI] 1.4-8.9; p=0.008). As a time-dependent covariate, wound healing was associated with less MALE (HR 0.23; 95% CI 0.10-0.53; p<0.001), and MALE was more frequent in patients with unhealed wounds (23% vs 11%; p<0.0001) (Figure - A). There was significantly less MALE in patients whose wounds healed within 4 months (24% vs 10%; p=0.032) (Figure - B), and less major amputation in those with healed wounds within 3 months (16% vs 5%; p=0.033). After multivariate adjustment for age, presence of diabetes, renal function, wound size, and procedural failure, independent predictors of MALE were wound healing as a time-dependent covariate (HR 0.18; 95% CI 0.08 - 0.40; p<0.0001), and creatinine ≥ 2 (HR 2.3; 95% CI 1.3-4.2; p=0.005). Conclusions: A shorter time to wound healing is associated with less MALE in patients with CLI after endovascular therapy. Efforts should be made to achieve wound healing as quickly as possible in this population, especially in those with renal dysfunction.

Background. In gastric cancer, various surveillance strategies are suggested in international guidelines. The current study is intended to evaluate the current strategies and provide more personalized proposals for personalized cancer medicine. Materials and Methods. In the aggregate, 9191 patients with gastric cancer after gastrectomy from 1998 to 2009 were selected from the Surveillance, Epidemiology, and End Results database. Disease-specific survival was analyzed by Kaplan-Meier method and the log-rank test. Cox proportional hazards regression analyses were used to confirm the independent prognostic factors. As well, hazard ratio (HR) curves were used to compare the risk of death over time. Conditional survival (CS) was applied to dynamically assess the prognosis after each follow-up. Results. Comparisons from HR curves on different stages showed that earlier stages had distinctly lower HR than advanced stages. The curve of stage IIA was flat and more likely the same as that of stage I while that of stage IIB is like that of stage III with an obvious peak. After estimating CS at intervals of three months, six months, and 12 months in different periods, stages I and IIA had high levels of CS all along, while there were visible differences among CS levels of stages IIB and III. Conclusions. The frequency of follow-up for early stages, like stages I and IIA, could be every six months or longer in the first three years and annually thereafter. And those with unfavorable conditions, such as stages IIB and III, could be followed up much more frequently and sufficiently than usual.

Abstract Background This retrospective analysis was undertaken to evaluate the efficiency of SIRT with Y-90 microspheres and determined prognostic factors affecting patients with unresectable HCC. Methods A total of 97 patients diagnosed with unresectable HCC who underwent SIRT with Y-90 microspheres. Patient survival was assessed using the Kaplan–Meier method, and prognostic factors affecting survival were assessed using log-rank tests and Cox proportional hazards regression. Results Among the 97 patients (90 males, mean age 60.4 ± 12.3 years) who underwent SIRT, the median clinical follow-up was 16.4 (1.8–62) months. The median overall survival (OS) was 23.9 ± 2.4 months. Tumor response according to the Modified RECIST in patients followed up beyond 6 months included a complete response (CR) to treatment in 12 patients (18.8%), partial response (PR) in 23 (35.8%), stable disease (SD) in 8 (12.5%), and progressive disease (PD) in 21 (32.8%). Factors associated with longer OS included age > 65 years, BCLC stage B, tumor size < 5 cm, tumor burden < 25%, and tumor response (CR/PR). In multivariate analysis, unilobar disease and objective tumor response (CR/PR) were predictors of longer OS. Conclusion SIRT was an effective treatment for unresectable HCC. Unilobar disease before SIRT and tumor response (CR/PR) were positive prognostic factors.

560 Background: Adjuvant chemotherapy for breast cancer is associated with the development of secondary AML, but this risk in an older population has not been previously quantified. Methods: We queried data from the Surveillance, Epidemiology, and End Results-Medicare (SEER-Medicare) database for women who were diagnosed with nonmetastatic breast cancer from 1992–1999. We compared the risk of AML in patients with and without adjuvant chemotherapy (C), and by differing C regimens. The primary endpoint was a claim with an inpatient or outpatient diagnosis of AML (ICD-09 codes 205–208). Risk of AML was estimated using the method of Kaplan-Meier. Cox proportional hazards models were used to determine factors independently associated with AML. Results: 36,904 patients were included in this observational study, 4,572 who had received adjuvant C and 32,332 who had not. The median patient age was 75.3 (66.0–103.3). The median follow up was 63 months (13–132). Patients who received C were significantly younger, had more advanced stage disease, and had lower comorbidity scores (p<0.001). The unadjusted risk of developing AML at 10 years after any adjuvant C for breast cancer was 1.6% versus 1.1% for women who had not received C. The adjusted HR for AML with adjuvant C was 1.72 (1.16–2.54) compared to women who did not receive C. HR for radiation was 1.21 (0.86–1.70). HR was higher with increasing age but p>0.05. An analysis was performed among women who received C. When compared to other C regimens, anthracycline-based therapy (A) conveyed a significantly higher hazard for AML HR 2.17 (1.08–4.38), while patients who received A plus taxanes (T) did not have a significant increase in risk HR1.29 (0.44–3.82) nor did patients who received T with some other C HR 1.50 (0.34–6.67). Another significant independent predictor of AML included GCSF use HR 2.21 (1.14–4.25). In addition, increasing A dose was associated with higher risk of AML (p<0.05). Conclusions: There is a small but real increase in AML after adjuvant chemotherapy for breast cancer in older women. The risk appears to be highest from A-based regimens, most of which also contained cyclophosphamide, and may be dose-dependent. T do not appear to increase risk. The role of GCSF should be further explored. No significant financial relationships to disclose.

3542 Background: Stage IV colon cancer treatment may include resection of the primary tumor. Current use of primary tumor surgery (PTS) in clinical practice is unknown. This study examined utilization and determinants of PTS and evaluated its effect on survival. Methods: Using national Surveillance, Epidemiology, and End Results registry data, stage IV colon cancer patients diagnosed from 1998-2008 were identified. Data on demographics, PTS, and tumor features were collected. Temporal changes in receipt of PTS were examined over 3 periods (1998-2000, 2001-2004, 2005-2008). Multiple logistic regression was used to identify significant determinants of PTS. 1- and 3-year cancer-specific survival was calculated in PTS and non-PTS patients. Cox proportional hazards models examined the effect of PTS on mortality risk. Results: 16,029 patients were identified. Median age was 69 (IQR: 57-78), and 50% were male. Approximately 67% of patients received PTS. Receipt of PTS significantly declined from 72% in 1998-2000 to 68% in 2001-2004, and 63% in 2005-2008 (p<0.01). Results from the logistic regression analysis showed that patients who were younger, white, married, had right sided cancer and higher tumor grade were more likely to receive PTS (all p<0.01). The 1- and 3-year survival was higher in patients who received PTS compared with those who did not (1-year: 55% (95% CI: 54-56) vs. 24% (95% CI: 23-26); 3-year: 19% (95% CI: 19-20) vs. 4% (95%CI: 3.4-4.9)). Adjusted for demographics and tumor features, risk of mortality was 54% (HR=0.46; 95% CI: 0.44-0.48) lower in patients who received PTS than those without PTS. Recent year of diagnosis (HR=0.88; 95% CI: 0.75-0.80) and being married (HR=0.90, 95% CI: 0.86-0.95) were associated with lower mortality. Older age (HR=1.48; 95% CI: 1.39-1.56), black race (HR=1.09; 95% CI: 1.03-1.15), right sided cancer (HR=1.21; 95% CI: 1.17-1.26), and poorly differentiated tumors (HR= 1.62; 95% CI: 1.46-1.80) were associated with increased mortality. Conclusions: PTS utilization for stage IV colon cancer has significantly declined, yet survival was higher in patients who received PTS. However, these findings are limited by the absence of co-morbidity and chemotherapy data.
