67 Background: Chemoradiotherapy (CRT) of esophageal cancer has been proposed as an alternative to esophagectomy given the favourable survival rate and mild toxicity. However, no comparative study is reported between esophagectomy and CRT in stage I esophageal squamous cell carcinoma. Methods: A total of 54 patients treated by definitive CRT and 116 patients treated by esophagectomy at out institution between February 1995 and August 2008 were included in the analysis. Overall survival and recurrence rates were evaluated. Results: Of 170 patients who had clinical stage I esophageal squamous cell carcinoma and treated by definitive CRT or esophagectomy, 169 patients (99%) were completely followed up. CRT mainly consisted of two cycles of cisplatin and fluorouracil with concurrent radiotherapy of 60 Gy in 30 fractions. Median (range) observation period was 67 (10–171) months in SURG group and 30 (4–77) months in CRT group. In CRT group grade 3 or grade 4 hematological or non-hematological adverse effects were seen in 24 (44.4%) patients. 1-year and 3-year overall survival rates were 97.4% and 85.5% in the SURG group and 98.1% and 88.7% in the CRT group (P = 0.78). By using Cox proportional hazards modelling, overall survival was comparable between the 2 groups after adjusting for age, sex, and size of cancer. Hazard ratio of CRT for overall survival was 0.95 (95% CI: 0.37-2.47). The incidence or local recurrence including metachronous esophageal cancer was significantly higher in the CRT group than the SURG group (P < 0.0001). All recurrences were intramucosal carcinomas and all of them were cured after the salvage treatment mainly using endoscopy. Conclusions: Overall survival rate of CRT was comparable with esophagectomy despite high local recurrence rate. Local recurrent carcinoma is endoscopically treatable in all patients without influence on overall survival. CRT appears to be a reasonable alternative to esophagectomy in patients with stage I esophageal cancer. No significant financial relationships to disclose.

AbstractLung squamous cell carcinoma (LUSC) possesses a poor prognosis even for stages I–III resected patients. Reliable prognostic biomarkers that can stratify and predict clinical outcomes for stage I–III resected LUSC patients are urgently needed. Based on gene expression of LUSC tissue samples from five public datasets, consisting of 687 cases, we developed an immune-related prognostic model (IPM) according to immune genes from ImmPort database. Then, we comprehensively analyzed the immune microenvironment and mutation burden that are significantly associated with this model. According to the IPM, patients were stratified into high- and low-risk groups with markedly distinct survival benefits. We found that patients with high immune risk possessed a higher proportion of immunosuppressive cells such as macrophages M0, and presented higher expression of CD47, CD73, SIRPA, and TIM-3. Moreover, When further stratified based on the tumor mutation burden (TMB) and risk score, patients with high TMB and low immune risk had a remarkable prolonged overall survival compared to patients with low TMB and high immune risk. Finally, a nomogram combing the IPM with clinical factors was established to provide a more precise evaluation of prognosis. The proposed immune relevant model is a promising biomarker for predicting overall survival in stage I–III LUSC. Thus, it may shed light on identifying patient subset at high risk of adverse prognosis from an immunological perspective.

The incidence and histological type of esophageal cancer are highly variable depending on geographic location and race/ethnicity. Here we want to determine if racial difference exists in the molecular features of esophageal cancer. We firstly confirmed that the incidence rate of esophagus adenocarcinoma (EA) was higher in Whites than in Asians and Blacks, while the incidence of esophageal squamous cell carcinoma (ESCC) was highest in Asians. Then we compared the genome-wide somatic mutations, methylation, and gene expression to identify differential genes by race. The mutation frequencies of some genes in the same pathway showed opposite difference between Asian and White patients, but their functional effects to the pathway may be consistent. The global patterns of methylation and expression were similar, which reflected the common characteristics of ESCC tumors from different populations. A small number of genes had significant differences between Asians and Whites. More interesting, the racial differences of COL11A1 were consistent across multiple molecular levels, with higher mutation frequency, higher methylation, and lower expression in White patients. This indicated that COL11A1 might play important roles in ESCC, especially in White population. Additional studies are needed to further explore their functions in esophageal cancer.

Abstract   Esophageal squamous cell carcinoma (ESCC) as a common malignancy is prevalent in East Asia and in eastern and southern Africa. Although pembrolizumab, nivolumab and camrelizumab are respectively recommended as second-line treatment for advanced ESCC due to improved overall survival (OS), objective response rate (ORR) was modest. New effective treatments are needed. Hence, the study of camrelizumab plus apatinib (VEGFR2 inhibitor) as second-line treatment for advanced ESCC was performed. Methods This ongoing phase II trial (NCT03736863) in six sites in China enrolled pts aged 18-75 with unresectable locally advanced, locally recurrent, or metastatic ESCC that progressed or were intolerant after first-line chemotherapy, and an ECOG performance status of 0-1. Pts received 200 mg camrelizumab intravenously every 2 weeks and apatinib 250 mg orally once per day in 4-week cycles until disease progression, unacceptable adverse events (AEs) or withdrawal of consent. The primary endpoint was investigator-assessed ORR. Secondary endpoints included disease control rate (DCR), progression-free survival (PFS) and OS. Results At data cutoff (Feb 28, 2021), 52 pts were enrolled, including 42 males and 50 with distant metastases, with the median age of 62 years. In the evaluable population of 39 pts, ORR without confirmation was 43.59% and DCR was 94.87%. The median duration of response was 6.9 months (95% CI 4.57–9.23). The median PFS was 6.8 month (95% CI 2.66–10.94). The 12-month overall survival was 52.2%. A total of 80.8% of pts had treatment-related AEs (TRAEs) with 46.2% of grade ≥ 3 TRAEs. The safety profile of camrelizumab and apatinib was consistent with other anti–PD-1 antibodies and angiogenesis inhibitors. Conclusion This is the first study that evaluates the combination anti–PD-1 antibody and anti-angiogenesis inhibitor as a second-line therapy for advanced ESCC. Camrelizumab plus apatinib showed encouraging clinical efficacy and acceptable safety. Further phase III randomized trials are warranted.

Overall Survival Time

The indoleamine 2,3-dioxygenase-(IDO-) mediated microenvironment plays an important role in tumor immune escape. However, the inhibitory effects of IDO on the CD8+tumour-infiltrating lymphocytes (CD8+TILs) in esophageal squamous cell carcinoma (ESCC) have not been clarified yet. Here, we found that the level of IDO expression in ESCC tumor specimens correlated with a reduction in the number of CD8+TILs. Patients with high IDO expression and a low number of CD8+TILs had significantly impaired overall survival time. IDO expression and functional enzyme activity in ESCC cell lines could be induced by IFNγ. When exposed to the milieu generated by IDO-expressing Eca109 cells, the CD8+TILs were suppressed in proliferation, and their cytolytic functions against target tumor cells were lost. These results suggested that impairing CD8+TIL functions by IDO expressed in ESCC possibly contributed to the finding that patients with higher IDO expression have more aggressive disease progression and shorter overall survival time.
