Purpose: To determine the relationship, in patients with adenocarcinoma of the colon, between survival and the number of lymph nodes analyzed from surgical specimens. Patients and Methods: Intergroup Trial INT-0089 is a mature trial of adjuvant chemotherapy for high-risk patients with stage II and stage III colon cancer. We performed a secondary analysis of this group with overall survival (OS) as the main end point. Cause-specific survival (CSS) and disease-free survival were secondary end points. Rates for these outcome measures were estimated using Kaplan-Meier methodology. Log-rank test was used to compare overall curves, and Cox proportional hazards regression was used to multivariately assess predictors of outcome. Results: The median number of lymph nodes removed at colectomy was 11 (range, one to 87). Of the 3,411 assessable patients, 648 had no evidence of lymph node metastasis. Multivariate analyses were performed on the node-positive and node-negative groups separately to ascertain the effect of lymph node removal. Survival decreased with increasing number of lymph node involvement (P = .0001 for all three survival end points). After controlling for the number of nodes involved, survival increased as more nodes were analyzed (P = .0001 for all three end points). Even when no nodes were involved, OS and CSS improved as more lymph nodes were analyzed (P = .0005 and P = .007, respectively). Conclusion: The number of lymph nodes analyzed for staging colon cancers is, itself, a prognostic variable on outcome. The impact of this variable is such that it may be an important variable to include in evaluating future trials.

Abstract Background Lymph node dissection (LND) is of great significance in intrahepatic cholangiocarcinoma (ICC). Although the National Comprehensive Cancer Network (NCCN) guidelines recommend routine LND in ICC, the effects of LND remains controversial. This study aimed to explore the role of LND and some related issues and of in ICC. Methods Patients were identified in two Chinese academic centers. Inverse probability of treatment weighting (IPTW) was used to reduce bias. Kaplan–Meier curves and Cox proportional hazards models were used to compare overall survival (OS) and disease-free survival (DFS). Results Of 232 patients, 177 (76.3%) underwent LND, and 71 (40.1%) had metastatic lymph nodes. A minimum of 6 lymph nodes were dissected in 66 patients (37.3%). LND did not improve the prognosis of ICC. LNM > 3 may have worse OS and DFS than LNM 1–3, especially in the LND >  = 6 group. For patients who did not underwent LND, the adjuvant treatment group had better OS and DFS. Conclusions The proportions of patients who underwent LND and removed >  = 6 lymph nodes were not high enough. LND has no definite predictive effect on prognosis. Patients with 4 or more LNMs may have a worse prognosis than patients with 1–3 LNMs. Adjuvant therapy may benefit patients of nLND.

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.

Lymph Node Retrieval

Many colorectal resections do not meet the minimum of 12 lymph nodes (LNs) recommended by the American Joint Committee on Cancer for accurate staging of colorectal cancer. The aim of this study was to investigate factors affecting the number of the adequate nodal yield in colorectal specimens subject to routine pathological assessment. We have retrospectively analysed the data of 2319 curatively resected colorectal cancer patients in San Raffaele Scientific Institute, Milan, between 1993 and 2017 (1259 colon cancer patients and 675 rectal cancer patients plus 385 rectal cancer patients who underwent neoadjuvant therapy). The factors influencing lymph node retrieval were subjected to uni- and multivariate analyses. Moreover, a survival analysis was carried out to verify the prognostic implications of nodal counts. The mean number of evaluated nodes was 24.08±11.4, 20.34±11.8, and 15.33±9.64 in surgically treated right-sided colon cancer, left-sided colon cancer, and rectal tumors, respectively. More than 12 lymph nodes were reported in surgical specimens in 1094 (86.9%) cases in the colon cohort and in 425 (63%) cases in the rectal cohort, and patients who underwent neoadjuvant chemoradiation were analysed separately. On univariate analysis of the colon cancer group, higher LNs counts were associated with female sex, right colon cancer, emergency surgery, pT3-T4 diseases, higher tumor size, and resected specimen length. On multivariate analysis right colon tumors, larger mean size of tumor, length of specimen, pT3-T4 disease, and female sex were found to significantly affect lymph node retrieval. Colon cancer patients with 12 or more lymph nodes removed had a significantly better long-term survival than those with 11 or fewer nodes (P=0.002, log-rank test). Rectal cancer patients with 12 or more lymph nodes removed approached but did not reach a statistically different survival (P=0.055, log-rank test). Multiple tumor and patients’ factors are associated with lymph node yield, but only the removal of at least 12 lymph nodes will reliably determine lymph node status.

Purpose Polymorphisms in tamoxifen metabolizing genes affect the plasma concentration of tamoxifen metabolites, but their effect on clinical outcome is unknown. Methods We determined cytochrome P450 (CYP)2D6 (*4 and *6) and CYP3A5 (*3) genotype from paraffin-embedded tumor samples and buccal cells (living patients) in tamoxifen-treated women enrolled onto a North Central Cancer Treatment Group adjuvant breast cancer trial. The relationship between genotype and disease outcome was determined using the log-rank test and Cox proportional hazards modeling. Results Paraffin blocks were obtained from 223 of 256 eligible patients, and buccal cells were obtained from 17 living women. CYP2D6 (*4 and *6) and CYP3A5 (*3) genotypes were determined from 190, 194, and 205 patient samples and in 17 living women. The concordance rate between buccal and tumor genotype was 100%. Women with the CYP2D6 *4/*4 genotype had worse relapse-free time (RF-time; P = .023) and disease-free survival (DFS; P = .012), but not overall survival (P = .169) and did not experience moderate to severe hot flashes relative to women heterozygous or homozygous for the wild-type allele. In the multivariate analysis, women with the CYP2D6 *4/*4 genotype still tended to have worse RFS (hazard ratio [HR], 1.85; P = .176) and DFS (HR, 1.86; P = .089). The CYP3A5*3 variant was not associated with any of these clinical outcomes. Conclusion In tamoxifen-treated patients, women with the CYP2D6 *4/*4 genotype tend to have a higher risk of disease relapse and a lower incidence of hot flashes, which is consistent with our previous observation that CYP2D6 is responsible for the metabolic activation of tamoxifen to endoxifen.

21072 Background: Axillary lymph node metastasis has proven to be the most important factor affecting overall survival (OS) and disease free survival (DFS) in patients with breast cancer. Recent evidence suggests that axillary lymph node ratio (LNR) may be at least as important as absolute number of involved lymph nodes in predicting OS and DFS. The aim of this retrospective study is to evaluate the impact of axillary nodal ratios in node-positive breast cancer as a prognostic factor for survival. Methods: Data from 1181 patients with stage I, II and III breast cancer diagnosed at AUBMC between 1990 and 2001 were studied. The median age at diagnosis was 50 years (23 - 88); the median number of lymph nodes dissected was 17 (0 - 49). Survival was compared in 737 patients with node-positive disease according to a LNR below or more than 0.25 (defined as number of involved lymph nodes divided by total dissected axillary lymph nodes). Results: Patients with LNR = 0.25 had a median follow-up of 30 months (1.2–156) and a median DFS of 26 months (1–156). The 5-year survival was 26.2% (94/358) and the 5-year DFS was 22.9% (82/358). Patients with LNR <0.25 had a median follow-up of 36 months (1.2–157) and a median DFS of 36 months (1–157). The 5-year survival of 33.2% (245/737) and the 5-year DFS was 29.8 % (220/737). LNR showed significance as a continuous variable and a categorical variable (0, < 0.25, and = 0.25) with a p < 0.001 Conclusions: LNR significantly predicts OS and DFS in node-positive primary breast cancer.

6524 Background: The retrieval of ≥12 lymph nodes in a colorectal cancer surgical specimen is an established quality metric. The impact of targeted education to improve nodal yield at community hospitals has not been studied. We initiated an intensive educational program through the Fox Chase Cancer Center Partner (FCCCP) hospitals to improve nodal retrieval in colon cancer specimens. Methods: At 12 FCCCP community hospitals from 2004–05, educational initiatives were conducted by FCCC staff and included group presentations at hospital tumor boards, cancer and quality committees, and regional CME. Individual presentations to pathologists and surgeons were held. Tumor registry data were retrospectively collected from FCCCP from 2003 (pre-intervention) to 2006 (post-intervention) for patients undergoing curative colon cancer surgery. Data abstracted were age, sex, race, stage, surgical procedure, and total number of nodes examined. The primary end point was % surgical specimens with ≥12 lymph nodes. Obtaining at least 250 records per year would allow ≥90% power to detect a change from a baseline level of ∼40% to ≥50% after intervention. Results: Data from 4,208 patients from 12 FCCCP hospitals were collected. Overall characteristics: male/female (48%/52%), race (W 83%, AA 7%, other 10%), age (<50:6%, 50–70: 34%, >70:60%), node ± (39%/61%). The % of colon cancer operations with ≥12 nodes significantly increased over the four years of the study (Table, p<.00001). This difference persisted when pooling years before and after the intervention (2003–04 vs. 2005–06, p <0.0001). There was no difference in nodal yield between two pre-intervention years (2003 vs. 2004, p=0.1). No differences in other characteristics such as age, sex, race, or % lymph node positive were noted between years. Conclusions: A multi-intervention targeted educational initiative in a large community cancer network is feasible and associated with increased colon cancer nodal retrieval.

584 Background: Right and left-sided colon cancers are embryonically distinct and present differently. Recently, there has been growing belief that sidedness could be independently associated with survival outcomes. This has important clinical implications regarding the prognostication, management and surveillance of colon cancer patients. Hence, we aim to investigate the impact of sidedness on survival in our patient population in this study. Methods: Patients who had primary treatment naïve colon cancer who underwent curative surgical resection in our institution from September 2002 to December 2010 were included in this study. Demographic and clinicopathological data was collected from electronic records and clinical charts. Tumours arising from the cecum, ascending colon, hepatic flexure and transverse colon were considered right-sided, while those arising from splenic flexure and descending colon were considered left-sided. Cancers of the rectosigmoid junction and rectum were excluded. Kaplan-Meier curves and log-rank test were used to compare overall, locoregional recurrence-free and distant recurrence-free survivals (OS, LRFS, DRFS respectively) between both groups. Multivariate analysis was performed using Cox regression proportional hazards. Results: 389 patients were included in this study. 238 had left-sided tumours while the remaining 151 had right-sided tumours. In our cohort, right-sided tumours were associated with older age and mucinous histology. Kaplan-Meier curves plotted showed improved LRFS in left-sided tumours (p = 0.04, median survival not reached) but no significant difference in OS and DRFS. On multivariate analysis, sidedness was also found to be an independent prognostic factor for LRFS but not OS and DRFS despite factoring in age, size of tumour, pT, pN and histology. Conclusions: Our study suggests that left-sided tumours in primary colon cancer are independently prognostic for improved locoregional survival as compared to the right-sided tumours, even after taking into account other known factors such as age, staging and histology.

Abstract Background: To investigate the relationship between tumour deposits(TDs) with the clinicopathological characteristics,prognosis of gastric cancer and tumour-infiltrating lymphocytes( TILs）.Methods: The pathological findings of 369 patients with gastric cancer were retrospectively analysed to observe the expression of TDs, and the levels of stromal TILs . The relationships between TDs status, clinicopathological characteristics, and TILs infiltration level were compared using the chi-square test, and rank data were tested using the rank sum test. Kaplan-Meier was used for survival analysis, and the log-rank test was used to determine the differences in survival curves between groups. The prognostic value of TDs was assessed using multivariate Cox proportional hazards regression analysis.Results: TDs were significantly associated with sex, Lymphovascular invasion, Perineural invasion, pathological TNM stage, and clinical stage (all P<0.05). TILs levels were lower in TDs(+) group and higher in TDs(-) group. TDs(+) group had poor Disease-free survival, cancer-specific survival , and overall survival as compared with TDs(-) groups.Conclusions: TDs is negatively correlated with TILs , and TDs+ was an Independent predictors of the prognosis of gastric cancer.

Biomarker-guided treatment for patients with colon cancer is needed. We tested ABCG2 and topoisomerase 1 (TOP1) mRNA expression as predictive biomarkers for irinotecan benefit in the PETACC-3 patient cohort. The present study included 580 patients with mRNA expression data from Stage III colon cancer samples from the PETACC-3 study, which randomized the patients to Fluorouracil/leucovorin (5FUL) +/− irinotecan. The primary end-points were recurrence free survival (RFS) and overall survival (OS). Patients were divided into one group with high ABCG2 expression (above median) and low TOP-1 expression (below 75 percentile) (“resistant”) (n = 216) and another group including all other combinations of these two genes (“sensitive”) (n = 364). The rationale for the cut-offs were based on the distribution of expression levels in the PETACC-3 Stage II set of patients, where ABCG2 was unimodal and TOP1 was bimodal with a high expression level mode in the top quarter of the patients. Cox proportional hazards regression was used to estimate the hazard ratios and the association between variables and end-points and log-rank tests to assess the statistical significance of differences in survival between groups. Kaplan-Meier estimates of the survival functions were used for visualization and estimation of survival rates at specific time points. Significant differences were found for both RFS (Hazard ratio (HR): 0.63 (0.44–0.92); p = 0.016) and OS (HR: 0.60 (0.39–0.93); p = 0.02) between the two biomarker groups when the patients received FOLFIRI (5FUL+irinotecan). Considering only the Microsatellite Stable (MSS) and Microsatellite Instability-Low (MSI-L) patients (n = 470), the differences were even more pronounced. In contrast, no significant differences were observed between the groups when patients received 5FUL alone. This study shows that the combination of ABCG2 and TOP1 gene expression significantly divided the Stage III colon cancer patients into two groups regarding benefit from adjuvant treatment with FOLFIRI but not 5FUL.

6559 Background: The incidence of colorectal cancer (CRC) in young adults is increasing. Minority populations with CRC are known to have worse outcome. The objective of this study is to evaluate the impact of race on the outcome of young adults with CRC. Methods: Data were obtained from all US hospitals that contributed to the National Cancer Database (NCDB) between 2004 and 2013. Univariate and multivariate testing was done to identify factors associated with patient outcome. Kaplan-Meier analysis and Cox proportional hazards models were used for association between patient characteristics and survival. Results: A total of 83,449 patients between 18 and 50 years of age were identified. The mean age was 43.6 years (SD±6), with a male preponderance (53.9%). About 72% were non-Hispanic Whites (NHW) while African Americans (AA) made up 15.1%. Distribution across stages I-IV was 15.6%, 22.4%, 33.9% and 27% consecutively, similar among the races. 41.8% of NHW and 28.4% of AA had rectal cancers (p<0.001). Despite equally receiving standard of care (SOC) as per NCCN guidelines, AA had significantly lower 5year survival rates (58.8%) compared to Hispanics (64.8%) and NHW (66.9%; HR 1.42; 1.38-1.46; p<0.001). Patients with colon cancer had worse outcome compared to rectal cancer (HR 1.21; 1.18-1.24; P<0.001). In terms of survival, NHW (HR 0.85; 0.81-0.88; p<0.001) and Hispanics (HR 0.75; 0.70-0.79; p<0.001) were more likely to benefit from chemotherapy compared to AA. As expected, SOC utilization was associated with improved survival across all racial groups, especially in AA with HR of 0.64 (0.60 – 0.69; p<0.001). Conclusions: Despite comparable rates of standard of care utilization, AA young adults with CRC had worse outcomes compared to other races. Colon cancer was significantly more common in AA than rectal cancers, which may have contributed to their worse outcomes. [Table: see text]
