Abstract OBJECTIVES Our goal was to compare short- and long-term outcomes between 3-field lymphadenectomy (3-FL) and modern 2-field lymphadenectomy (2-FL) in patients with thoracic oesophageal squamous cell carcinoma. METHODS We reviewed clinical outcomes for 298 patients with thoracic oesophageal squamous cell carcinoma who underwent 3-FL or modern 2-FL from March 2008 to December 2013 at a major cancer hospital in Guangzhou, southern China. Propensity score matching was used to balance baseline differences, and 83 pairs of cases were selected. Postoperative complications, recurrence patterns and survival outcomes were compared between the 2 groups. RESULTS Compared with modern 2-FL, 3-FL led to higher overall operative morbidity rates [78.3% vs 61.4%, odds ratio (OR) 2.266, 95% confidence interval (CI) 1.143–4.490; P = 0.019], with higher recurrent nerve palsy rates (47.0% vs 19.3%, OR 3.712, 95% CI 1.852–7.438; P < 0.0001), more respiratory failures (18.1% vs 6.0%, OR 3.441, 95% CI 1.189–9.963; P = 0.023) and longer postoperative hospital stays (23 vs 17 days, P = 0.002). The 5-year overall survival rate (58.5% vs 59.4%; P = 0.960) and the 5-year disease-free survival rate 50.1% vs 54.5%; P = 0.482) were comparable between the 2 groups. Multivariable analysis showed that additional cervical lymph node dissection was not associated with overall survival [hazard ratio (HR) 1.039, 95% CI 0.637–1.696; P = 0.878] and disease-free survival (HR 0.868, 95% CI 0.548–1.376; P = 0.547). The overall recurrence rate and cervical nodal recurrence rate were not significantly different between the 2 groups. CONCLUSIONS Additional cervical lymphadenectomy did not lead to added survival benefit when compared with modern 2-FL in patients with thoracic oesophageal squamous cell carcinoma. Recurrence was similar in patients undergoing 3-FL and modern 2-FL. 3-FL resulted in more postoperative complications.

Abstract   There is limited evidence for effectiveness of adjuvant chemotherapy in esophageal squamous cell carcinoma. We conducted a multi-center randomized controlled trial to assess whether adjuvant Capecitabine and Cisplatin improve survival compared with surgery only among patients with resectable esophageal squamous cell carcinoma. Methods This is a multicenter randomized controlled trials conducted at five hospitals in Korea from Mar 2005 to Dec 2018. Patients were eligible if they underwent curative resection for esophageal squamous cell carcinoma and diagnosed with pathologic T2–3 or N1 stage, according to 6th edition of TNM cancer staging system. Patients who were diagnosed with cervical esophageal cancer, had previous history of cancer, or received neoadjuvant therapy were excluded. Intervention group received 4 cycles of adjuvant chemotherapy (Capecitabine 1,000 mg/m2 b.i.d for 14 days and intravenous Cisplatin 75 mg/m2 at Day1, every 3 weeks). The primary endpoint was disease free survival. Results 136 patients were randomly assigned to adjuvant chemotherapy group (n = 68) or surgery alone group (n = 68). Seven patients who rejected chemotherapy after randomization were excluded from the final analysis. The cumulative incidence of recurrence within 18 months after surgery was significantly lower in the adjuvant chemotherapy group compared to the surgery alone group (Hazard Ratio (HR), 0.45; 95% Confidence Interval (CI), 0.22–0.91). After long-term follow-up (median 3.3 years, maximum 14 years), disease free survival and overall survival were not different between two groups. (HR, 0.77; 95% CI, 0.49–1.18 and HR, 0.85; 95% CI, 0.55–1.34, respectively.) Conclusion Adjuvant chemotherapy after curative resection in patients with esophageal squamous cell carcinoma reduced early recurrence but this does not extend to long-term disease free and overall survival due to limited sample size. Additional randomized controlled trials with larger sample would be necessary to confirm the effectiveness of adjuvant chemotherapy in esophageal squamous cell carcinoma.

AbstractAnal Squamous Cell Carcinoma (ASCC) is a rare cancer that has a rapidly increasing incidence in areas with highly developed economies. ASCC is strongly associated with HIV and there appears to be increasing numbers of younger male persons living with HIV (PLWH) diagnosed with ASCC. This is a retrospective cohort study of HIV positive and HIV negative patients diagnosed with primary ASCC between January 2000 and January 2020 in a demographic group with high prevalence rates of HIV. One Hundred and seventy six patients were included, and clinical data was retrieved from multiple, prospective databases. A clinical subgroup was identified in this cohort of younger HIV positive males who were more likely to have had a prior diagnosis of Anal Intraepithelial Neoplasia (AIN). Gender and HIV status had no effect on staging or disease-free survival. PLWH were more likely to develop a recurrence (p < 0.000) but had a longer time to recurrence than HIV negative patients, however this was not statistically significant (46.1 months vs. 17.5 months; p = 0.077). Patients known to have a previous diagnosis of AIN were more likely to have earlier staging and local tumour excision. Five-year Disease-Free Survival was associated with tumour size and the absence of nodal or metastatic disease (p < 0.000).

BackgroundPatients with newly diagnosed, resected, head and neck squamous cell carcinoma (HNSCC) with high-risk (positive margins, extracapsular spread [ECE]) or intermediate-risk pathological features have an estimated 1-year disease free survival (DFS) of 65% and 69%, respectively.1 PD-1/PD-L1 immune checkpoint blockade has improved survival of patients with recurrent/metastatic HNSCC, and preclinical models indicate radiation upregulates PD-L1.2 Therefore, we hypothesized that pre and post-operative administration of the PD-1 inhibitor pembrolizumab would improve 1-year DFS for patients with resectable, loco-regionally advanced (clinical T3/4 and/or ≥2 nodal metastases) HNSCC (NCT02641093).MethodsEligible patients received pembrolizumab (200 mg I.V. x 1) 1-3 weeks before resection. Adjuvant pembrolizumab (q3 wks x 6 doses) was administered with weekly cisplatin (40mg/m2 X 6) and radiation (60-66Gy) for those with high-risk features and radiation alone for patients with intermediate-risk features. The primary endpoint was DFS, which was compared by log-rank test to historical controls (RTOG 9501). Evidence of pathological response to neoadjuvant pembrolizumab was evaluated by comparing pre- and post-surgical tumor specimens for treatment effect (TE) defined as tumor necrosis and/or histiocytic inflammation and giant cell reaction to keratinaceous debris. Response was classified as none (NPR, <20%), partial (PPR, ≥20% and <90%) and major (MPR, ≥90%) pathological response. Gene expression analysis in paired tumor specimens was evaluated by Nanostring.ResultsSixty-six of 84 enrolled patients had received adjuvant pembrolizumab and therefore were evaluable for DFS at the time of interim analysis. Patient characteristics included: median age 59 (range of 27 – 76) years; 30% female; 85% oral cavity, 11% larynx, and 2% human papillomavirus negative oropharynx; 85% clinical T3/4 and 68% ≥2N; 41(51%) high-risk (positive margins, 49%; ECE, 80%). At a median follow-up of 16 months, 1-year DFS was 66% (95%CI 0.48-0.84) in the high-risk group (p=1) and 91% (95%CI 0.79-1) in the intermediate-risk group (versus 69% in RTOG 9501, p=0.05) (figure 1). Among 70 patients evaluable for pathological response, TE was scored as NPR in 40, PPR in 27, and MPR in 3 patients. Patients with pathological response that were also evaluable for DFS (PPR + MPR) had significantly improved 1-year DFS when compared with those with NPR (100% versus 57%, p=0.0033; HR = 0.18 [95%CI 0.05-0.64]) (figure 2). PPR/MPR was associated with robust macrophage infiltration via Nanostring.Abstract 809 Figure 1Disease Free Survival by Pathological RiskPatients were stratified by pathological risk and DFS was measuredAbstract 809 Figure 2Disease Free Survival by Pathological ResponsePaired patient tissue was assessed for treatment effect (TE) and patients with greater than or equal to 20% TE were considered to have developed pathological response. Patients were stratified into responders and non-responders and DFS was determined.ConclusionsNeoadjuvant and adjuvant pembrolizumab led to high DFS in intermediate-risk, but not high-risk, resected HNSCC patients. Pathological response to neoadjuvant pembrolizumab was associated with high 1-year DFS.AcknowledgementsWe’d like to acknowledge the UCCC clinical trials office for their hard work on this study as well as our patients.
