However, radiation injury before surgery may delay wound healing. We performed cervical anastomosis directly inside the left supraclavicular fossa (SCF), the irradiation target for esophageal cancer. The significance of radiation injury in patients with cervical anastomotic leak (AL) remains unclear. Thus, we assessed the influence of radiation on cervical AL in patients undergoing preoperative CCRT followed by esophagectomy.Patients and Methods: We defined the SYC zone, a portion of the region overlapping the left SCF. The radiation dose to the SYC zone was analyzed and correlated with AL in patients with locally advanced esophageal squamous cell carcinoma (ESCC) who were administered preoperative CCRT (radiation dose with 50– 50.4 Gy/25-28 Fx to the primary esophageal tumor) followed by esophagectomy between October 2009 and January 2018. Receiver operating characteristic curve analysis and logistic regression were used to identify the optimal radiation factor to predict AL and the cutoff value.Results: The optimal radiation factor to predict AL was the mean dose to the SYC zone (area under the curve (AUC)=0.642), and the cutoff point of the mean dose was 48.55 Gray (Gy). For a mean SYC zone dose ≥ 48.55 Gy, the AL risk was sevenfold greater than that for < 48.55 Gy (OR = 7.805; 95% CI: 1.184 to 51.446; P value = 0.033).Conclusion: Recognizing the SYC zone as an organ at risk and performing radiation evaluation are meaningful. A reduced mean dose of the SYC zone below 48.55 Gy results in a lower cervical AL rate following esophagectomy.Keywords: esophageal squamous cell carcinoma, preoperative concurrent chemoradiotherapy, radiation therapy

In this study, we evaluated whether liver cirrhosis is an independent risk factor for the survival of patients with lung cancer.Materials and Methods: We conducted a retrospective, multicenter, propensity-matched study of lung cancer patients with and without liver cirrhosis. To determine differences in survival, we sought to identify risk factors associated with poor outcomes using Kaplan–Meier survival analysis and Cox proportional hazards regression.Results: There were no statistically significant differences in the baseline clinical characteristics of patients between the cirrhosis and non-cirrhosis groups. The median overall survival of patients with and without cirrhosis was 13.07 months (95% confidence interval [CI]: 10.56– 16.84) and 13.67 months (95% CI: 10.42– 16.91), respectively (p=0.76). Cox proportional hazards regression analysis revealed that liver cirrhosis was not an independent risk factor for poor outcome (hazard ratio [HR]: 1.057, 95% CI: 0.805– 1.388, p=0.690). In patients with cirrhosis, lower serum albumin levels, higher Charlson Comorbidity Index score, advanced-stage lung cancer, and treatment modality were factors associated with poor outcome. Increase in serum albumin by 1 g was associated with a 30% reduction in the risk of mortality (HR: 0.700, 95% CI: 0.494– 0.993, p=0.045). While every point increase in the Charlson Comorbidity Index score by 1 point was linked to a 9% higher risk of mortality (HR: 1.090, 95% CI: 1.023– 1.161, p=0.007).Conclusion: The survival rates of lung cancer patients with and without cirrhosis did not differ significantly. Higher serum albumin levels and lower Charlson Comorbidity Index scores were associated with improved survival.Keywords: liver cirrhosis, lung neoplasm, outcome, survival
