          Abstract

          Aim: This study aimed to evaluate the cost-effectiveness of pembrolizumab compared with that of chemotherapy in the second-line treatment of locally advanced or metastatic esophageal squamous cell carcinoma (ESCC) patients with a combined positive score ≥10. Methods: A Markov model was established to compare the lifetime costs and quality-adjusted life years (QALYs) of different treatment options. Sensitivity analysis was performed to test the stability of the model. Results: The increased utility and cost of pembrolizumab were 0.442 QALYs and US$11,826.79 compared with those of chemotherapy. The incremental cost–effectiveness ratio was US$26,757.45/QALY, which was less than the threshold of three-times the GDP per capita. The prices of paclitaxel and pembrolizumab were the most important influencing factors. Conclusion: Pembrolizumab is a cost-effective second-line treatment of ESCC.

          Global Cancer Statistics 2018: GLOBOCAN Estimates of Incidence and Mortality Worldwide for 36 Cancers in 185 Countries

          This article provides a status report on the global burden of cancer worldwide using the GLOBOCAN 2018 estimates of cancer incidence and mortality produced by the International Agency for Research on Cancer, with a focus on geographic variability across 20 world regions. There will be an estimated 18.1 million new cancer cases (17.0 million excluding nonmelanoma skin cancer) and 9.6 million cancer deaths (9.5 million excluding nonmelanoma skin cancer) in 2018. In both sexes combined, lung cancer is the most commonly diagnosed cancer (11.6% of the total cases) and the leading cause of cancer death (18.4% of the total cancer deaths), closely followed by female breast cancer (11.6%), prostate cancer (7.1%), and colorectal cancer (6.1%) for incidence and colorectal cancer (9.2%), stomach cancer (8.2%), and liver cancer (8.2%) for mortality. Lung cancer is the most frequent cancer and the leading cause of cancer death among males, followed by prostate and colorectal cancer (for incidence) and liver and stomach cancer (for mortality). Among females, breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death, followed by colorectal and lung cancer (for incidence), and vice versa (for mortality); cervical cancer ranks fourth for both incidence and mortality. The most frequently diagnosed cancer and the leading cause of cancer death, however, substantially vary across countries and within each country depending on the degree of economic development and associated social and life style factors. It is noteworthy that high-quality cancer registry data, the basis for planning and implementing evidence-based cancer control programs, are not available in most low- and middle-income countries. The Global Initiative for Cancer Registry Development is an international partnership that supports better estimation, as well as the collection and use of local data, to prioritize and evaluate national cancer control efforts.

            Epidemiologic differences in esophageal cancer between Asian and Western populations

            Esophageal cancer is a common cancer worldwide and has a poor prognosis. The incidence of esophageal squamous cell cancer has been decreasing, whereas the incidence of esophageal adenocarcinoma has been increasing rapidly, particularly in Western men. Squamous cell cancer continues to be the major type of esophageal cancer in Asia, and the main risk factors include tobacco smoking, alcohol consumption, hot beverage drinking, and poor nutrition. In contrast, esophageal adenocarcinoma predominately affects the whites, and the risk factors include smoking, obesity, and gastroesophageal reflux disease. In addition, Asians and Caucasians may have different susceptibilities to esophageal cancer due to different heritage backgrounds. However, comparison studies between these two populations are limited and need to be addressed in the near future. Ethnic differences should be taken into account in preventive and clinical practices.

              Adjuvant chemotherapy with paclitaxel and cisplatin in lymph node-positive thoracic esophageal squamous cell carcinoma

              Objective No standard postoperative adjuvant chemotherapy has ever been established in node-positive esophageal squamous cell carcinoma (ESCC). This is a study to explore the effect of postoperative paclitaxel (PTX) and cisplatin (DDP) in lymph node-positive, completely resected thoracic ESCC patients. Methods We conducted a prospective phase II trial. Patients had pathologically node-positive thoracic ESCC with negative margins. Outcomes of disease-free survival (DFS) and overall survival (OS) were compared with a matched historical control cohort. The postoperative chemotherapy regimen consisted of 4 to 6 cycles of PTX 150 mg/m2 administered intravenously on d 1 followed by DDP 50 mg/m2 on d 2 every 14 d. Results Forty-three patients were accrued from December 2007 to May 2012 at Cancer Hospital of Chinese Academy of Medical Sciences for adjuvant chemotherapy. The historical control group consisted of 80 patients who received complete resection but no adjuvant chemotherapy during the same period of time. Of the 43 patients with adjuvant chemotherapy, 37 (86.0%) patients completed 4 to 6 cycles of chemotherapy. The 3-year DFS rates were 56.3% in the adjuvant group and 34.6% in the control group (P=0.006). The 3-year OS rates were 55.0% in the adjuvant group and 37.5% in the control group (P=0.013). Multivariate analysis revealed that postoperative chemotherapy was the significant predictor for improved OS (P=0.005). Conclusions Biweekly adjuvant PTX and DDP might improve 3-year DFS and OS in lymph node-positive, curatively resected thoracic ESCC patients. These conclusions warrant further study in randomized phase III clinical trials.
