207 Background: Local failure is a major problem after chemoradiotherapy (CRT) in patients with esophageal squamous cell carcinoma (ESCC), and salvage surgery presents high morbidity and mortality rates. We have introduced photodynamic therapy (PDT) and endoscopic resection (ER) for local failures to develop a less invasive salvage treatment.The aim of this retrospective study was to clarify the long-term outcome of salvage endoscopic treatments (SET). Methods: Between 1998 and 2008, 716 patients with ESCC were treated with definitive CRT in our institution. There were 314 patients with incomplete response and 103 with local recurrence after achieving complete response (CR) once. The indication criteria of SET were as follows: 1) absence of lymph node and distant metastasis and 2) local failures limited within T2. ER was performed for local failures limited to T1b (SM1), and PDT was performed for lesions invading T1b (SM2) or T2, in patients who could not tolerate or who refused surgery. We assessed overall survival (OS), relapse-free survival (RFS), and also prognostic factors. This study was approved by an institutional review board. Results: A total of 164 patients with local failure underwent SET (ER: 58, PDT: 106). The characteristics before CRT were as follows: T1/2/3/4, 44/25/75/20; N0/1, 85/79; stage I/II/III/IV, 35/59/57/13; and those of before SET were as follows: T1/2, 126/38; residue/recurrence, 76/88. ER achieved curative resection in 51 (87.9%), and PDT achieved CR in 61 (57.5%) patients. With a median follow up period of 73 months, the OS and RFS rates at 5 years from SET were 38.6% (95% CI 31.0–46.2) and 28.1% (95% CI 21.0–35.2). Multivariate analysis revealed 2 preferable prognostic factors in common for OS and RFS, N0 before CRT (OS HR: 0.47 [95% CI 0.32–0.69], RFS HR: 0.61 [95%CI 0.43–0.87]) and a period from initiation of CRT to SET longer than 6 months (OS HR: 0.57 [95%CI 0.39–0.84], RFS HR: 0.67 [0.47–0.95]). After 5 years of follow up, 58 patients (35.4%) were alive without any metastasis under esophagus preservation. Conclusions: SET demonstrated a favorable outcome in an analysis of a large number of patients with local failure after definitive CRT for ESCC.

Abstract Background Esophageal squamous cell carcinoma (ESCC) invading the muscularis mucosae (MM) and submucosa up to 200 µm (SM1) has a risk of metastasis. The aims of this study were to investigate the long-term outcome of endoscopic submucosal dissection (ESD) for MM/SM1 ESCC and to assess the management after ESD in our hospital. Methods This was a retrospective cohort study conducted at a single institution. Patients with MM or SM1 ESCC who were treated with ESD were included. Additional prophylactic therapy was added if lymphovascular involvement (LVI) was noted in the ESD specimens. Results A total of 102 patients were analyzed. The median length of follow-up was 71.5 months (range 9 – 144 months) and the median number of CTs was 6 (range 0 – 24). LVI was found in 21 patients (20.6 %), and 12 patients underwent additional prophylactic therapy. The 5-year overall survival, disease-specific survival, and tumor-free survival rates were 84.1 %, 97.5 %, and 82.1 %, respectively. A total of 26 patients died, but only 2 of them died from ESCC. The cumulative metastasis rate was 11.8 %, and LVI was a significant predictor of metastasis (hazard ratio 5.42, 95 % confidence interval 1.39 – 21.18; P = 0.02). There were no differences between patients with MM ESCC and those with SM1 ESCC. Conclusions The long-term outcome after ESD for MM/SM1 ESCC was favorable with additional prophylactic therapy and strict adherence to follow-up. These results indicate that our management decision based on LVI is a valid approach and that ESD can be offered as a therapeutic option to MM/SM1 ESCCs.

207 Background:ATTRACTION-1/ONO-4538-07 (AT-1), an open-label, single-arm, multicenter phase 2 clinical trial conducted in Japan, evaluated the clinical activity and safety of nivolumab in patients with advanced esophageal squamous cell carcinoma (ESCC) refractory/intolerant to fluoropyrimidine-, platinum-, and taxane-based chemotherapy. We previously reported the 2-year follow-up findings of AT-1, in which nivolumab demonstrated antitumor activity with a manageable safety profile for these patients. Here we report the final findings from AT-1 at a minimum follow-up of 5 years. Methods:Patients aged ≥20 years with an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0-1 received 3 mg/kg nivolumab intravenously every 2 weeks in 6-week cycles until disease progression or unacceptable toxicity. The primary endpoint was centrally-assessed objective response rate (ORR), defined as the proportion of patients whose best overall response was either a complete or partial response. Secondary endpoints included overall survival (OS), investigator-assessed ORR, progression-free survival (PFS), change in tumor burden, time to response, time to disease progression, and duration of response. Results:Between February 25 and November 14, 2014, a total of 65 patients were enrolled. Sixty-four patients were evaluated for the efficacy, and all patients were evaluated for the safety. At the final database lock on August 6, 2020, 11 (17.2%, 95% confidence interval [CI] 9.9-28.2) of 64 patients had an objective response by central assessment. The median OS was 10.8 months (95% CI, 7.4-13.9), and the estimated 5-year OS rate was 6.3% (95% CI, 2.0-14.0). The median PFS was 1.5 months (95% CI, 1.4-2.8), and the estimated 5-year PFS rate was 6.8% (95% CI, 2.2-15.1). Treatment-related adverse events that occurred with a frequency of > 10% were diarrhea and rash. The presentation will include characteristics of long-term survivors as well as detailed efficacy and safety data of nivolumab. Conclusions:This final assessment represents the longest follow-up of patients with advanced ESCC treated with nivolumab. Nivolumab demonstrated continued long-term efficacy in these patients based on a minimum of 5-year long-term survival update of AT-1. Furthermore, no new safety signals with nivolumab were identified during long-term follow-up. These findings are consistent with those of nivolumab monotherapy for various types of cancer. Clinical trial information: No.142422.

Nutritional Index

Abstract Background Preoperative nutritional and inflammation indexes have been shown to be associated with postoperative complications and the prognosis of patients with a malignant tumor. We evaluated several clinicopathological prognostic factors in patients with resected esophageal squamous cell carcinoma (ESCC). Methods Seventy-eight patients who underwent curative resection for ESCC were included in this retrospective study. The associations of body mass index (BMI), the prognostic nutritional index (PNI), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and protein-albumin ratio (CAR) with various clinicopathological factors were evaluated. Results In multivariate analyses, only low PNI (<46.8) independently and significantly predicted overall survival (OS) (P=0.002). Conclusions The PNI is a simple, useful marker for predicting the long-term prognosis of patients with ESCC after esophagectomy. The PNI should be included in the routine assessment of patients with ESCC.
