The Impact

255 Background: Pancreatic adenocarcinoma (PDAC) is a lethal malignancy, representing the 4th leading cause of cancer deaths. Our 2011 institutional protocol guides that patients with Stage I/II PDAC receive neoadjuvant chemotherapy (FOLFIRINOX or gemcitabine- nab-paclitaxel); a similar protocol is followed with patients with Stage III disease. The aim of the study is to determine if potentially curative surgery provides added survival benefit, compared to neoadjuvant chemotherapy alone. Methods: Patients who received neoadjuvant chemotherapy and who were diagnosed with stage I-III PDAC from 2011-2017 at a tertiary medical center were included in this prospectively-collected, retrospective analysis. The primary endpoint was overall survival (OS). Kaplan-Meier curves are compared using Log-rank. Cox proportional hazards were used to adjust for confounders. Results: 105 patients met inclusion criteria: 38 (36%) had Stage I disease (n = 18 had neoadjuvant chemotherapy and surgery [N+S], n = 20 had neoadjuvant chemotherapy [N] alone), 44 (42%) had stage II (N+S n = 20, N n = 24), 23 (22%) had stage III (N+S n = 4, N n = 19). There was no difference in 5-year OS regardless of treatment regimen in patients with Stage I (median OS N+S 22.5 mo vs N 27.9 mo; p = 0.99, HR 1.00, 95%CI 0.74-1.35) or Stage II disease (median OS N+S 28.7 mo vs N 27.6 mo; p = 0.69; HR 1.06, 95%CI 0.79-1.41). There is a trend towards improved OS with N+S in those with Stage III disease (median OS N+S 46.0 mo vs N 14.5 mo, p = 0.08), but the number who underwent resection is low (17%), limiting this analysis. Conclusions: In patients with Stage I-II PDAC, potentially curative surgery may not provide additional survival benefit beyond that afforded by modern day neoadjuvant chemotherapy. Stage III outcomes are limited by small numbers, and the impact of surgery is unclear. It may be possible that the locally unresectable tumor that is rendered resectable with neoadjuvant chemotherapy may be associated with a more favorable biology, such that surgery offers added survival benefit. Additional large-scale trials are needed to confirm whether newer therapies may obviate the need for resection in select patients.

The Impact

e15052 Background: Pancreatic resection is the only known curative option for pancreatic adenocarcinoma. Resection has been previously reported to be underutilized in patients with early stage disease. To develop a better understanding of this issue and control for treatment selection factors, we examined the relationship between geographic area resection rates and survival in patients with stage I/II pancreatic cancer. Methods: We queried Surveillance, Epidemiology, and End Results (SEER) data for patients with stage I/II cancer of the pancreatic head diagnosed from 2004-2009. We excluded patients with less than 3mo survival. Resection rates were calculated within Health Service Areas (HSAs) across all 18 SEER regions. Resection rate was defined as the number of patients who had an operation divided by the total number diagnosed with early stage pancreatic cancer. Multivariate Cox regression was used to estimate the overall survival effect of HSA rates while controlling for age, gender, marital status, poverty level, education, and AJCC stage. Results: 8,323 patients with stage I (n=1,454) and stage II (n=6,869) disease were analyzed. Pancreatectomy was performed in 476 patients (32.7%) with stage I disease and 3,846 (56.0%) with stage II disease. HSA resection rates were arranged into five groups (quintiles) which ranged from 42.7 to 65.7% (Table). Across the quintiles, median overall survival increased from 11 to 14 months, suggesting a positive association with resection rate. Multivariate analysis revealed that for every 10.00% increase in resection rate, the risk of overall death decreased by 5.26% (p<0.001). Conclusions: Patients with early stage pancreatic cancer who live in areas with higher resection rates have longer average survival times. Because geography should not influence treatment response, we conclude that efforts to raise resection rates should increase survival times in patients for whom there is uncertainty about the risk/benefits of resection.

For this reason, cardiac biomarkers are used in European 2015 and Mayo clinic 2012, two representative staging systems for AL amyloidosis. Since the NT-proBNP levels of the existing AL amyloidosis staging systems are different, we tried to find the appropriate NT-proBNP level in our 16-year AL amyloidosis patient cohort. Newly diagnoded AL amylodosis patients between August 2004 and July 2020 were included in this study (n=401). Patients who did not have laboratory results for staging had been exclude (n=86). Among them, 86 patients of stage III and 145 patients of stage IV patients (according to Mayo clinic 2012 stage) were analyzed (n=231). Of the 231 stage III, IV patients, 25, 82, 47, and 77 patients were classified as a group of NT-proBNP ≤1800, 1800 &lt; NT-proBNP ≤5000, 5000&lt; NT-proBNP ≤8000, and NT-proBNP &gt;8000 (ng/L), respectively. The characteristics and overall survival of each group were investigated through statistical analysis. Age at diagnosis (p=0.016), ECOG (p=0.046), serum creatinine(p=0.001), and Estimated glomerular filtration rate (eGFR) (p=0.003) had statistically significant differences in the groups divided by the NT-proBNP criteria. With 54.4 months of median follow up, the overall survivals analyzed by Mayo clinic 2012 were stage I: not reached, stage II: 49.6 months, stage III: 46.8 months, and stage IV: 11.9months, respectively. As a result of European 2015 analysis, stage I: not reached, stage II: 65.9 months, stage IIIa: 41.4 months, stage IIIb: 4.3 months.) In our analysis according to NT-proBNP (ng/L) in stage III and IV patients, the overall survival of NT-proBNP ≤1800 group has not yet been reached. The median OS of group 1,800&lt;NT-proBNP ≤5000, 5000&lt; NT-proBNP ≤8000, and NT-proBNP &gt;8000 were 54.8 months, 11.9 months, and 4.5 months, respectively (p &lt;0.001). The Kaplan-Meier's curve for OS had a clear difference at NT-proBNP 5000 value. On the basis of NT-proBNP, the OS of less than 5000 group was 62 months, and the OS of 5000 or more group was 5.9 months. In analysis of factors affecting the OS, statistically significant results were age at diagnosis (p = 0.018), ECOG (p = 0.002), and NT-proBNP 5000 ng/L or higher (p &lt; 0.001). The dFLC included in the Mayo clinic 2012 was found to have a statistically insignificant on the overall survival (p=0.584). Although disease stage is important in predicting the prognosis of AL amyloidosis, it was revealed that NT-proBNP is the most important factor in predicting survival prognosis. In this study we confirmed that AL amyloid patients with high NT-proBNP of &gt;5000 ng/L may have particularly poor survival rate. When staging AL amyloidosis, it can be considered based on NT-proBNP 5000 ng/L level. Figure 1 Figure 1. Disclosures No relevant conflicts of interest to declare.

125 Background: Pathologic staging in colorectal cancer (CRC) is crucial in patient management. Data regarding the impact of size/horizontal tumor extent is limited, contradictory and currently excluded from the American Joint Committee on Cancer (AJCC) staging model. However, a previously published SEER analysis showed that AJCC stages I and IIIA have similar 2- and 5- year survival rates, and worse rates for stage II. Using the largest cohort to date, we report the impact of primary tumor size on CRC survival. Methods: Data were obtained from all US hospitals that contributed to the National Cancer Database (NCDB) between 2010 and 2015. Univariate and multivariate analyses were performed to identify factors associated with patient outcome. Kaplan-Meier analysis and Cox proportional hazards models were used to assess the association between tumor/patient characteristics and overall survival (OS). Results: A total of 61,145 patients were identified with a similar gender distribution (M/F:50.9%/49.1%). The mean age was 62.7years (SD+/-14.1) and 82% were non-Hispanic Whites. Majority had colon primary (82.7%) and 82.4% had microsatellite stable (MSS) disease. Distribution across stages I-IV was 20.1%, 32.1%, 34.7% and 13.2% respectively. Among the total study population, AJCC stage correlated closely with OS on multivariate analysis (HR 1.49, 2.29, 8.38 for stages II to IV compared to stage I), while the distinguishing power for tumor size was relatively mild (HR 1.19 and 1.33 for 5-10 cm and >5cm compared to <5cm). Among patients with stage II disease, tumors >10cm were associated with worse survival compared to those <5cm (HR 1.2; 1.03-1.39; p=0.22). Stage III disease also had differential survival rates; patients with tumors 5-10cm (HR 1.21; 1.14-1.28; p<0.001) and >10cm (HR 1.57; 1.37-1.80; p<0.001) had worse survival than those <5cm. Patients with stage II who did not receive adjuvant chemotherapy (CTX) had worse survival outcomes (HR 1.29; 1.08-1.55; p=0.005) compared to stage III disease who did. Accounting for tumor size, there was no statistically significant survival differences between stage I patients and stages II and III patients who received adjuvant chemotherapy. Conclusions: Tumors larger than 10cm have inferior outcomes among patients in the same AJCC stages. Stage II patients without adjuvant CTX did worse than stage III with CTX. Further studies are needed to clarify the role of tumor size in staging models. [Table: see text]

Purpose Adherence to evidence-based treatment guidelines has been proposed as a measure of cancer care quality. We sought to determine rates of and factors associated with adherence to the National Comprehensive Cancer Network (NCCN) treatment guidelines for colon cancer. Patients and Methods Patients within the National Cancer Data Base treated for colon adenocarcinoma (2003 to 2007) were identified. Adherence to stage-specific NCCN guidelines was determined based on disease stage. Hierarchical regression analyses were performed to identify factors predictive of adherence, overtreatment, and undertreatment. Results A total of 173,243 patients were included in the final cohort, 123,953 (71%) of whom were treated according to NCCN guidelines. Patients with stage I disease were more likely to receive guideline-based treatment (96%) than patients with stage II (low risk, 66%; high risk, 36%), III (71%), or IV (73%) disease (P < .001). Adherence to consensus-based guidelines increased over time. Factors associated with adherence across all stages included age, Charlson-Deyo comorbidity index score, later year of diagnosis, and insurance status. Among patients with high-risk stage II or stage III disease, older patients with pre-existing comorbidities and patients with lower socioeconomic status were less likely to be offered adjuvant chemotherapy. Among patients with stage I and II disease, young, healthy patients were more likely to be recommended chemotherapy, in discordance with NCCN guidelines. Conclusion Significant variation exists in the treatment of colon cancer, particularly in treatment of high-risk stage II and stage III disease. The impact of nonadherence to guidelines on patient outcomes needs to be further elucidated.

Abstract Hodgkin’s Disease (HD) is the most common lymphoma affecting young adults and teenagers. Bone marrow involvement is rare but if present, infers Stage IV disease and an inferior outcome. Adult studies have suggested that bone marrow examination (BME) may not be necessary unless certain risk factors are present. However, some pediatric centers continue to perform BME routinely on all children with HD. BME is invasive and generally performed under conscious sedation in children. We validated and administered an internet-based survey to examine the practice of all Canadian pediatric oncologists regarding BME in children with HD. We also retrospectively evaluated the impact of routine BME on the HD patients treated at our institution over the past 27 years. Forty-three percent of eligible physicians (n=93) completed the survey and 16 of a total of 17 Canadian pediatric oncology centers were represented. BME universally consisted of bilateral bone marrow aspirates and trephine biopsies. Routine BME for Stage III and IV disease was consistently practised nationally (by 92% and 97% of respondents, respectively). By contrast, 54% and 70% of respondents reported performing routine BME in low stage (Stage I and II) disease, respectively. Respondents were more likely to report performing routine BME in low stage patients, if their pediatric hematology/oncology training was entirely outside Canada (p=0.04 for Stage I and p=0.07 for Stage II) and if they practiced at smaller centers (p=0.05 for Stage I and p=0.03 for Stage II). There were no differences in practice regarding BME associated with the number of years in practice or the number of patients seen annually by the respondent. If not part of routine staging for all patients, BME was more likely performed if there were “B” symptoms, cytopenias, and/or bulky disease. Most respondents (95%) would proceed with BME following a positive PET scan. In the review of local institutional practice, 62 patients with HD and BME were eligible for analysis. Only 4 patients (6.5%) had a positive BME. No patient with otherwise low stage disease was found to have bone marrow involvement. Two patients, who would have been assigned as Stage III disease, were upstaged to Stage IV due to their BME. Comparison of staging with and without BME demonstrated no significant difference. Hemoglobin level was found to be the to be the only significant risk factor for marrow involvement based on univariate analysis(put in statisticp=0.006). Age, gender, histologic subtype, presence of “B” symptoms, and other blood parameters (white count, platelets, ESR and transaminases) were not significant factors. Practice regarding BME in children with low stage HD is highly variable across Canada. Bone marrow examination in pediatric patients with low stage HD should be abandoned, unless there is a specific indication to do so (for example positive PET scan or unexplained anemia). Moreover, BME does not appear to add any additional therapeutic direction for higher stage patients.

e15106 Background: Multiple studies have indicated the prognostic and potential predictive significance of primary tumor side in metastatic CRC. To date, the few studies examining its impact in early stage disease have either combined data across multiple stages or restricted analysis to overall survival (OS) data. A by stage analysis of the impact of tumor side on recurrence risk is critical if it is to impact adjuvant therapy decisions. Methods: We examined data from a multi-site Australian registry of consecutive patients diagnosed from 2003-2016. Tumors at and distal to the splenic flexure, including the rectum, were considered a left primary (LP). Rectal patients treated with initial chemoradiation were excluded. Clinico-pathologic and outcome data were examined. Data analysis was provided by the healthcare group at IBM Research Australia. Results: A total of 6123 patients were identified, of which 1046 (17.1%) had initial stage I, 1892 (30.9%) had stage II, 1708 (27.9%) had stage III, and 1477 (24.1%) had stage IV disease. Most patients were male (55.2%), and had a LP (n = 3818, 62.4%). Median age at diagnosis was 68.8 years, was higher in patients with a right primary (RP) (71.6 versus 67.0 years for LP, p < 0.001), with more females in the RP group (51.1% vs 41.0% for LP, p < 0.001). The proportion of RP varied by stage, highest in stage II (44.9%), lowest in stage IV (31.5%). For all stage IV disease, including metachronous cases, OS was worse with a RP (HR 1.32, 95% CI 1.14-1.53). For early stage cases, distant recurrence free survival (DRFS) was similar for RP vs LP for stage I (HR 0.63, 95% CI 0.32-1.23), better for stage II RP (HR 0.72, 95% CI 0.55-0.95) and worse for stage III RP disease (HR 1.22, 1.01-1.48). OS did not differ for RP vs LP for stage I or II disease, but was worse for stage III disease with a RP (HR 1.39, 95% CI 1.13-1.70). Furthermore, post recurrence survival was poorer in stage III RP disease (HR 1.61, 95% CI 1.33-1.96). Conclusions: Primary tumor side has potential as an important prognostic marker in early stage CRC. Our novel finding of a variable impact by stage indicate that an assessment of cohorts where recurrence data is available is critical to fully understanding the implications of tumor side for adjuvant therapy decision making.

Background: Breast cancer is the most common cancer in women across the world, with high incidence and mortality rates. Being a heterogeneous disease, gene expression profiling based analysis plays a significant role in understanding breast cancer. Since expression patterns of patients belonging to the same stage of breast cancer vary considerably, an integrated stage-wise analysis involving multiple samples is expected to give more comprehensive results and understanding of breast cancer. Objective: The objective of this study is to detect functionally significant modules from gene co-expression network of cancerous tissues and to extract prognostic genes related to multiple stages of breast cancer. Methods: To achieve this, a multiplex framework is modelled to map the multiple stages of breast cancer, which is followed by a modularity optimization method to identify functional modules from it. These functional modules are found to enrich many Gene Ontology terms significantly that are associated with cancer. Result and Discussion: predictive biomarkers are identified based on differential expression analysis of multiple stages of breast cancer. Conclusion: Our analysis identified 13 stage-I specific genes, 12 stage-II specific genes, and 42 stage-III specific genes that are significantly regulated and could be promising targets of breast cancer therapy. That apart, we could identify 29, 18 and 26 lncRNAs specific to stage I, stage II and stage III respectively.

Abstract Background Cardiac wild type transthyretin (ATTRwt) amyloidosis, formerly known as senile systemic amyloidosis, is an increasingly recognized, progressive, and fatal cardiomyopathy. Two biomarkers staging systems were proposed based on NT-proBNP (in both cases) and troponin or estimated glomerular filtration rate, that are able to predict survival in this population. The availability of novel effective treatments requires large studies to describe the natural history of the disease in different populations. Objective To describe the natural history of the disease in a large, prospective, national series. Methods Starting in 2007, we protocolized data collection in all the patients diagnosed at our center (n=400 up to 7/2019). Results The referrals to our center increased over time: 5 cases (1%) between 2007–2009, 33 (9%) in 2010–2012, 90 (22%) in 2013–2015 and 272 (68%) in 2016–2019. Median age was 76 years [interquartile range (IQR): 71–80 years] and 372 patients (93%) were males. One hundred and seventy-three (43%) had atrial fibrillation, 63 (15%) had a history of ischemic cardiomyopathy and 64 (15%) underwent pacemaker or ICD implantation. NYHA class was I in 58 subjects (16%), II in 225 (63%) and III in 74 (21%). Median NT-proBNP was 3064 ng/L (IQR: 1817–5579 ng/L), troponin I 0.096 ng/mL (IQR: 0.063–0.158 ng/mL), eGFR 62 mL/min (IQR: 50–78 mL/min). Median IVS was 17 mm (IQR: 15–19 mm), PW 16 mm (IQR: 14–18 mm) and EF 53% (IQR: 45–57%). One-hundred and forty-eight subjects (37%) had a concomitant monoclonal component in serum and/or urine and/or an abnormal free light chain ratio. In these patients, the diagnosis was confirmed by immunoelectron microscopy or mass spectrometry. In 252 (63%) the diagnosis was based on bone scintigraphy. DNA analysis for amyloidogenic mutations in transthyretin and apolipoprotein A-I genes was negative in all subjects. The median survival of the whole cohort was 59 months. The Mayo Clinic staging based on NT-proBNP (cutoff: 3000 ng/L) and troponin I (cutoff: 0.1 ng/mL) discriminated 3 different groups [stage I: 131 (35%), stage II: 123 (32%) and stage III: 127 (33%)] with different survival between stage I and II (median 86 vs. 81 months, P=0.04) and between stage II and III (median 81 vs. 62 months, P&lt;0.001). The UK staging system (NT-proBNP 3000 ng/L and eGFR 45 mL/min), discriminated three groups [stage I: 170 (45%), stage II: 165 (43%) and stage III: 45 (12%)] with a significant difference in survival: between stage I and stage II (86 vs. 52 months, P&lt;0.001) and between stage II and stage III (median survival 52 vs. 33 months, P=0.045). Conclusions This is one of the largest series of patients with cardiac ATTRwt reported so far. Referrals and diagnoses increased exponentially in recent years, One-third of patients has a concomitant monoclonal gammopathy and needed tissue typing. Both the current staging systems offered good discrimination of staging and were validated in our independent cohort. Funding Acknowledgement Type of funding source: None

Single Ventricle Palliation

Introduction: Single ventricle physiology management is challenging, especially in low-income countries. Objective: To report the palliation outcomes of single ventricle patients in a developing African country. Methods: We retrospectively studied 83 consecutive patients subjected to single ventricle palliation in a single center between March 2011 and December 2017. Preoperative data, surgical factors, postoperative results, and survival outcomes were analyzed. The patients were divided by palliation stage: I (pulmonary artery banding [PAB] or Blalock–Taussig shunt [BTS]), II (Glenn procedure), or III (Fontan procedure). Results: Of the 83 patients who underwent palliation (stages I-III), 38 deaths were observed (31 after stage I, six after stage II, and one after stage III) for an overall mortality of 45.7%. The main causes of operative mortality were multiple organ dysfunction due to sepsis, shunt occlusion, and cardiogenic shock. Twenty-eight survivors were lost to follow-up (22 after stage I, six after stage II). Thirteen stage II survivors are still waiting for stage III. The mean follow-up was 366 ± 369 days. Five-year survival was 28.4 % for PAB and 30.1% for BTS, while that for stage II and III was 49.8% and 57.1%, respectively. Age (hazard ratio, 0.61; 95% confidence interval: 0.47-0.7; P = .000) and weight at surgery (hazard ratio, 0.45; 95% confidence interval: 0.31-0.64; P = .002) impacted survival. Conclusion: A high-mortality rate was observed in this initial experience, mainly in stage I patients. A large number of patients were lost to follow-up. A task force to improve outcomes is urgently required.

Objectives. To investigate the prognostic impact of the number of dissected lymph nodes (LNs) in gastric cancer after curative distal gastrectomy.Methods. The survival of 634 patients who underwent curative distal gastrectomy from 1995 to 2004 was retrieved. Long-term surgical outcomes and associations between the number of dissected LNs and the 5-year survival rate were investigated.Results. The number of dissected LNs was one of the most important prognostic indicators. Among patients with comparable T category, the larger the number of dissected LNs was, the better the survival would be (). The linear regression showed that a significant survival improvement based on increasing retrieved LNs for stage II, III and IV (). A cut-point analysis yields the greatest variance of survival rate difference at the levels of 15 LNs (stage I), 25 LNs (stage II) and 30 LNs (stage III).Conclusion. The number of dissected LNs is an independent prognostic factor for gastric cancer. To improve the long-term survival of patients with gastric cancer, removing at least 15 LNs for stage I, 25 LNs for stage II, and 30 LNs for stage III patients during curative distal gastrectomy is recommended.
