Lymph Node Retrieval

Abstract Introduction Previous studies evaluating the association of LN yield and survival presented conflicting results and many may be influenced by confounding and stage migration. This study aimed to evaluate whether the quality indicator ‘retrieval of at least 15 lymph nodes (LNs)’ is associated with better long-term survival and more accurate pathological staging in patients with esophageal cancer treated with neoadjuvant chemoradiotherapy and resection. Methods Data of esophageal cancer patients who underwent neoadjuvant chemoradiotherapy and surgery between 2011-2016 was retrieved from the Dutch Upper Gastrointestinal Cancer Audit. Patients with <15 LNs and ≥15 LNs were compared after propensity score matching based on patient and tumor characteristics. The primary endpoint was 3-year survival. To evaluate the effect of LN yield on the accuracy of pathological staging, pathological N-stage was evaluated and 3-year survival was analyzed in a subgroup of patients node-negative disease. Results In 2260 of 3281 patients (67%) ≥15 LNs were retrieved. In total, 992 patients with ≥15 LNs were matched to 992 patients with <15 LNs. The 3-year survival did not differ between the two groups (57% versus 54%, p=0.28). pN+ was scored in 41% of patients with ≥15 LNs versus 35% of patients with <15 LNs. For node-negative patients, the 3-year survival was significantly better for patients with ≥15 LNs (69% versus 61%, p=0.01). Conclusions In this propensity score matched cohort, 3-year survival was comparable for patients with ≥15 LNs, although increasing nodal yield was associated with more accurate staging. In node-negative patients, 3-year survival was higher for patients with ≥15 LNs.

The Impact

644 Background: Steroids given at the induction of anaesthesia are associated with a reduction in the magnitude of the postoperative systemic inflammatory response and fewer complications following elective surgery for colorectal cancer (McSorley et al. Ann Surg Oncol 2017;24(8):2104-2112). The present study examined their impact on survival. Methods: Patients who underwent elective surgery, with curative intent, for stage I-III colorectal cancer at a single centre between 2008 and 2016 were included. Data on preoperative dexamethasone was obtained from anaesthetic records, and its impact on cancer specific (CSS) and overall survival (OS) assessed using Cox regression in an unmatched (n=556) and a propensity score matched cohort (n=276) (Table 1). Results: After excluding postoperative mortalities (n=3), there were 98 deaths (18%), with 57 (10%) due to cancer. Of those alive at censoring, the median follow up was 47 months (range 16-110). In the unmatched cohort, there was no significant association between dexamethasone and CSS (HR 0.90, 95% CI 0.52-1.53, p=0.688) or OS (HR 0.95, 95% CI 0.63-1.43, p=0.804). In the propensity score matched cohort, there was no significant association between dexamethasone and CSS (HR 1.18, 95% CI 0.55-2.53, p=0.668) or OS (HR 1.21, 95% CI 0.67-2.17), p=0.532). Conclusions: These results suggest that whilst preoperative steroids are associated with improved short term outcomes following surgery for colorectal cancer, they have no negative effect on long term outcomes.

Locally Advanced Esophageal Cancer

97 Background: The neoadjuvant chemoradiotherapy (nCRT) combined with surgery is hopeful to improve the prognosis of locally advanced esophageal cancer but it remains contentious. Several studies showed that nCRT could significantly improve 5-year OS rate of locally advanced esophageal cancer. However, other clinical trials did not come to the same conclusion. This study retrospectively analyzed the esophageal squamous cell cancer (ESCC) patients who received nCRT combined with surgery in our hospital to investigate the prognostic factors for the patients’ survival. Methods: 96 patients with ESCC who received nCRT combined with surgery in our hospital from January 2007 to December 2014 were retrospectively analyzed. They were diagnosed with preoperation stage T3-4N0-1M0. Among them, 34 cases were in stage IIc and 62 cases were in stage IIIc. Prognostic factors for these patients were analyzed. Results: 26 (27.1%) patients received pathologic complete response (pCR) and 80 (83.3%) patients had downstage. The 1-, 3-, 5-year OS rates of all patients were 91.5%, 63.5%, 55.1%. The 1-, 3-, 5-year OS rates of tumor regression grading(TRG) 1, 2, 3 were 88.9%, 54.1%, 36.5% vs 88.4%, 56.4%, 48.6% vs 95.5%, 90.4%, 90.4%(Р = 0.014). The 1-, 3-, 5-year OS rates of pCR and non-pCR were 95.5%, 90.4%, 90.4% vs 88.6%, 55.6%, 45.4%(Р = 0.004). The 1-, 3-, 5-year OS rates of pathological lymph node negative(ypN-) and positive(ypN+) were 97.3%, 71.1%, 59.8% vs 66.7%, 33.3%, 33.3%(Р = 0.002). The 1-, 3-, 5-year OS rates of downstage and no-downstage were 94.9%, 73.9%, 65.6% vs 75.0%, 18.8%, 12.5% (Р = 0.000). Multivariate analyses identified pathologic lymph nodal status (RR = 2.193, 95%CI:1.018-4.726, Р = 0.045) and downstage category (RR = 3.520, 95%CI:1.638-7.568, Р = 0.001) were significant independent prognostic parameters. Conclusions: The nCRT combined with surgery achieved a high rate of long-term survival without increasing postoperative complications in patients with locally advanced ESCC. TRG was closely associated with patient’s prognosis, especially for patients with pCR. Pathologic lymph nodal status and downstage category were independent influencing factors for long-term survival.

Surgery Outcomes

150 Background: The objectives of this study were to compare peri-operative and long-term outcomes from esophageal cancer (EC) (i) that arose in a previously radiated field (ECRF) versus primary (PEC) and among ECRF patients (ii) radiotherapy-induced (RIEC) versus non radiotherapy-induced EC (NRIEC). Methods: Data was collected from 30 European centers from 2000–2010. 2489 EC patients surgically treated were included in the PEC group and 136 in the ECRF group, including 61 in the NRIEC group and 75 in the RIEC group. Propensity score matching analyses were used to compensate for differences in baseline characteristics. Results: Compared to the PEC group, the ECRF group was characterized by less use of neoadjuvant chemoradiotherapy (0% vs. 29.5%; P < 0.001), less pathological stage III/IV (31.6% vs 39.2%, P = 0.036), greater incidence of R1/2 margins (21.3% vs. 10.9%; P < 0.001), increased in-hospital mortality (14.0% vs. 7.1%; P = 0.003) and overall morbidity (68.4% vs. 56.4%, P = 0.006). After matching, 5-year overall (28.8% vs. 50.5%; HR = 1.53, 95% C.I. 1.15-2.04; P = 0.003) and event-free (32.2% vs. 42.5%; HR = 1.56, 95% C.I. 1.18-2.05; P = 0.002) survivals were significantly reduced in the ECRF group. There were no significant differences in incidence or pattern of tumor recurrence. Comparing RIEC and NRIEC groups, there were no significant differences in short- or long-term outcomes before and after matching. Conclusions: ECRF is associated with poorer long-term survival related to a reduced utilization of neoadjuvant chemoradiotherapy and an increased incidence of tumor margin involvement at surgery. Outcomes are dictated by the limitations related to previous radiotherapy administration more than the radiotherapy-induced carcinogenesis.
