87 Background: The optimal number of lymph nodes that should be harvested in esophageal cancer patients remains to be defined, particularly in patients that receive neoadjuvant therapies. We investigated the impact of nodal resection and survival in esophageal cancer patients treated with neoadjuvant chemoradiation (NT). Methods: Using our comprehensive esophageal cancer database we identified patients treated with NT followed by esophagectomy between 2000-2011. Clinical and pathologic data were compared using Fisher’s exact and chi-square while, Kaplan Meier estimates were used for survival analysis. Overall (OS) and disease-free survival (DFS) were compared with varying numbers of lymph nodes resected <10 and ≥10 (ST-1), <12 and ≥12 (ST-2), and <15 and ≥15 (ST-3). Multivariate analysis was analyzed by the Cox proportional hazard model. Results: We identified 358 patients treated with NT and esophagectomy with a median follow-up of 18.5 months (range, 0-116 months). There was no survival benefit demonstrated for patients with increased lymph nodes removed during their surgery (ST-1 OS p=0.400, DFS p=0.8727; ST-2 OS p=0.6833, DFS p=0.6092; ST-3 OS p=0.1798, DFS p=0.4028). Patients were further stratified by pathologic response to NT and nodal harvest. There were no differences in OS or DFS in patients with increased nodal harvest when analyzed by complete (pCR) (ST-1 OS p=0.7278, DFS p=0.3602; ST-2 OS p=0.6182, DFS p=0.3592; ST-3 OS p=0.4489, DFS p=0.6976), partial (pPR) (ST-1 OS p=0.3762, DFS p=0.5061; ST-2 OS p=0.8036, DFS p=0.6497; ST-3 OS p=0.0890, DFS p=0.3364), or non response (pNR) (ST-1 OS p=0.6825, DFS p=0.7161; ST-2 OS p=0.7084, DFS p=0.8351; ST-3 OS p=0.5002, DFS p=0.7314) to NT. Multivariate analysis demonstrated that age (p=0.028), t-stage (p=0.006), pPR (p=0.025), and pNR (p<0.0005) to NT were all independent predictors of mortality. Conclusions: In our experience, the number of lymph nodes resected was not predictive for overall or disease free survival in esophageal cancer patients treated with NT. In addition, extended lymph node resection did not improve survival for those with residual disease.

65 Background: The number of resected lymph nodes is associated with overall and disease-free survival in some gastrointestinal malignancies. The impact of nodal harvest during esophagectomy remains to be determined. We examined the influence of lymphadenectomy on overall survival in patients with esophageal cancer. Methods: Utilizing a prospectively maintained comprehensive esophageal cancer database we identified patients who underwent esophagectomy with between 1994 and 2011. The association between disease free survival (DFS), overall survival (OS) and nodal harvest was evaluated using multivariable Cox regression models. The number of harvested nodes was examined as a categorical variable based on strata(S): 1) ≤8, 2) 9-12, 3) 13-20, and 4) >20. Results: We identified 635 patients, 541 males and 94 females with a median age of 65 years (28-86) and median follow-up of 22 months (0-168). Adenocarcinoma 559 (88 %) was the predominant histology where as squamous cell carcinoma represented 76 (12%) of the cases. The 5-year OS and DFS rate for S1-S4 was (43%, 42%, 55%, and 36%, p=0.1836) and (44%, 37%, 46%, and 36%, p=0.5166) respectively. There were 209 patients with metastatic disease in 1 or more lymph nodes. The 5-year OS and DFS for S1-S4 was (17%, 31%, 21%, and 27%, p=0.4372) and (17%, 23%, 16%, and 25%, p=0.2726). There were 418 node negative patients. The 5-year OS and DFS rates by S1-S4 was (54%, 51%, 79%, and 26%, p=0.0538) and (55%, 48%, 64%, and 27%, p=0.3703). Multivariate analysis revealed that patients within S3 exhibited a survival benefit adjusted odds ratio (AOR) 0.57 (CI 0.360-0.916, p=0.020). However patients within S1 were more likely to die, AOR 1.74 (CI 1.09-2.78, p=0.020). No survival benefit was demonstrated for patients within (S4) AOR 1.11 (CI 0.60-2.09, p=0.731). There were 171 (27.5%) recurrences with a median time to recurrence of 12.2 (1-101) months. There were no differences in recurrences between strata p=0.129. Conclusions: We demonstrated that patients with ≤8 lymph nodes resected were more likely to die of their disease compared to those with 13-20 nodes resected. Additionally, extended lymphadenectomy (>20 nodes) does not increase the likelihood of proper staging and does not improve patient outcome.

102 Background: The optimal number of lymph nodes harvested remains controversial in patients with esophageal cancer. Pathologic response to neoadjuvant therapy (NT) has demonstrated improved survival. However, little is known regarding the impact of NT or nodal harvest in patients with squamous cell carcinoma (SCC) of the esophagus. We examined the extent of LN harvest and outcome in patients who underwent esophagectomy for SCC. Methods: After IRB approval, using a comprehensive esophageal cancer database we identified patients who underwent esophagectomy between 1994-2011. Clinical and pathologic data were compared using Fisher’s exact and chi-square when appropriate while Kaplan-Meier estimates were utilized for survival analysis. Nodal strata were set at 12 (ST-1), 15 (ST-2), and 20 nodes (ST-3). Pathologic response to NT was defined as complete (pCR), partial (pPR), or non-response (pNR). Results: We identified 76 patients who underwent esophagectomy for SCC between 1994-2011. The median age was 62.5 years (40-85 months) with median follow up of 18.5 months (1-157 months). 48 (63%) were male and 28 (37%) were female. Twenty-eight patients (37%) underwent primary esophagectomy alone (PE) while 48 (63%) patients were treated with NT. Extent of lymphadenectomy had no significant impact on overall survival (OS) or disease free survival (DFS) for the entire cohort ST-1 p=0.8 and p=0.9, ST-2 p=0.5 and p=0.4, and ST-3 p=0.5 and 0.4, respectively. Among the patients who received NT, pCR was observed in 28 (58%), pPR in 14 (29)%, and pNR in 6 (13)%. When examining the degree of pathologic response to treatment, extent of LN harvest had no significant impact on OS or DFS for patients who underwent esophagectomy after NT (p=ns across all strata). Conclusions: The extent of LN harvest failed to demonstrate an overall or disease free survival benefit in patients with squamous cell carcinoma of the esophagus. Moreover, patients treated with NT also did not benefit from increased nodal resection irrespective of their pathologic response.

Background. Surgery performed by a high-volume surgeon improves short-term outcomes. However, not much is known about long-term effects. Therefore we performed the current study to evaluate the impact of high-volume colorectal surgeons on survival.Methods. We conducted a retrospective analysis of our prospectively collected colorectal cancer database between 2004 and 2011. Patients were divided into two groups: operated on by a high-volume surgeon (>25 cases/year) or by a low-volume surgeon (<25 cases/year). Perioperative data were collected as well as follow-up, recurrence rates, and survival data.Results. 774 patients underwent resection for colorectal malignancies. Thirteen low-volume surgeons operated on 453 patients and 4 high-volume surgeons operated on 321 patients. Groups showed an equal distribution for preoperative characteristics, except a higher ASA-classification in the low-volume group. A high-volume surgeon proved to be an independent prognostic factor for disease-free survival in the multivariate analysisP=0.04. Although overall survival did show a significant difference in the univariate analysisP<0.001it failed to reach statistical significance in the multivariate analysisP=0.09.Conclusions. In our study, a higher number of colorectal cases performed per surgeon were associated with longer disease-free survival. Implementing high-volume surgery results in improved long-term outcome following colorectal cancer.

Abstract Aim The aim of this study was to assess whether a preoperative HH≥3cm had an impact on histopathologic tumor response after neoadjuvant treatment, as well as on overall and disease-free survival. Background & Methods Hiatal hernia (HH) and long-term gastroesophageal reflux are known risk factors for esophageal cancer. Previous data suggest a negative impact of large hiatal hernias on survival after esophagectomy, as well as an increased toxicity after neoadjuvant treatment (1), although evidence remains scarce and the mechanism is not fully elucidated. All consecutive patients who underwent surgical esophagectomy for adenocarcinoma or squamous cell cancer of the esophagus and gastro-esophageal junction from 2012-2018 were assessed. Baseline oesogastroduodenoscopy reports and CT-scan images were retrospectively reviewed to identify the presence of a HH of ≥3cm (2). Response to neoadjuvant treatment as assessed by the Mandard score (3), postoperative outcomes and survival were compared between HH and non-HH patients (defined as HH<3cm or no HH at all). Categorical variables were compared with the x2 or Fisher’s test, whereas continuous ones with the Mann-Whitney-U test. The Kaplan-Meier method and log-rank test were used for survival analyses. Results Among the 174 included patients, 44 (25.3%) had a HH≥3cm upon diagnosis. HH patients compared to the non-HH had significantly more Barrett’s metaplasia (52.3% vs 20%, p<0.001), although no differences in baseline stage were observed. HH patients presented a worse response to neoadjuvant treatment compared to non-HH patients (TRG 4-5 in 40.5% vs 21.3%, p=0.033). Among HH patients, perioperative chemotherapy compared to radiochemotherapy showed a trend to higher complete response rates (TRG 1 in 25% vs 11.5%, p=0.059). In the radiochemotherapy subgroup (n=112), HH patients had worse complete response rates than non-HH patients (TRG 1 in 11.5% vs 26.7% respectively, p=0.050). However, no differences in overall or disease-free survival were observed between HH and non-HH patients in the whole cohort or in subgroup analyses. Conclusion A HH≥3cm is frequently encountered in esophageal cancer patients. The presence of HH was associated with worse response to neoadjuvant treatment, especially radiochemotherapy. However, the presence HH did not have an impact on long-term survival and recurrence.

606 Background: To determine the importance of number of lymph nodes recovered on outcome in pathological node negative rectal cancer patients who had received chemo/radiotherapy prior to surgery. Methods: We retrospectively analysed data from 262 patients with locally advanced rectal cancer who received pre-operative chemo/radiotherapy at Castle Hill Hospital, Cottingham and Nottingham University Hospital between 2001 and 2008. Patients were treated with CT planned radiotherapy to a dose of 45-50 Gy in 25 fractions with concurrent fluoropyrimidine chemotherapy. Surgery was normally performed at an interval of 6-8 weeks. There were 152 patients who were found to be pathologically node negative for further analysis. Median follow-up was 51.5 months Patients were grouped into < 10 nodes recovered or > 10 nodes recovered. Disease free survival (DFS) and overall survival (OS) was assessed using Log rank test. Multivariate analysis was performed using Cox-regression analysis. Results: Of the 152 patients analysed, 67.1 % (n=102 ) had fewer than 10 nodes recovered and 32.8% (n=50) had greater than 10 nodes recovered. The median number of nodes recovered was 7 (range 0-39). There was a improvement in 5 year DFS and OS in group who had more than 10 nodes recovered compared to group with less than 10 nodes recovered ( DFS at 5yrs :86.5% vs. 61.5%, p=0.01, OS at 5 yrs : 77.8% vs. 67.4% , P =0.059). On multivariate analysis pathological T-stage , circumferential resection margin (CRM) status and number of lymph nodes recovered were found to be independent predictors of disease free survival (p=0.002). Conclusions: The number of lymph nodes retrieved following surgery for locally advanced rectal cancer patients following chemo/radiotherapy is an independent prognostic factor in pathologically node negative patients. This may need to be considered when making subsequent adjuvant chemotherapy decisions.

621 Background: Serological tumor markers: Cancer Antigen 15–3 (CA 15–3), Carcinoembryonic Antigen (CEA), have been investigated as useful markers for monitoring of response to treatment and for predicting outcome in breast cancer patients. Methods: A total of 820 breast cancer patients, treated over the period April 1999 through December 2003, had preoperative CA15–3 and CEA concentrations measured. The stage of the primary tumor ranged from 0 to IV. The median age of the patients was 47years (range 20–88 years old). The concentration of markers was investigated with regard to clinico-pathological parameters and patients outcome by both univariate and multivariate analysis. We determined the range of normality by the mean + 2 standard deviations of the markers distribution in populations of healthy females, who took an annual health screening program. Survival curves for disease free survival and death from disease were estimated by the method of Kaplan-Meier method and differences between groups in survival were tested using the log-rank test. All statistical analyses were carried out using SPSS statistics software (ver 10.5). Results: Among 820 patients, elevated preoperative level of CA15–3 and CEA was identified in 100 (12.2%) and 83 (10.1%) patients, respectively. Tumor size (>5cm), lymph node metastases (≥4), advanced stage (stage III and IV) were associated with significantly higher level of both preoperative CA15–3 and CEA. Elevated preoperative values of CA15–3 and CEA were associated with poor disease free survival (DFS, p=0.0019, p=0.0001, respectively) and distant relapse-free survival (DRFS, p=0.011, p=0.0034), but the level was marginal for overall survival (OS, p=0.0848, p=0.0895). By Cox’s multivariate analysis, younger age (<35 years), larger tumor size(>2cm), axillary node metastases, negative ER expression, elevated preoperative values of CA15–3 and CEA were independent prognostic factors for DFS and DRFS. Conclusions: High level of preoperative CA 15–3 and CEA might reflect a tumor burden, and is associated with advanced disease condition and disease-free survival. Measuring preoperative levels of CA 15–3 and CEA might be helpful for predicting the outcome and for planning the adjuvant therapy in breast cancer patients.
