| 2 | Impact of palliative therapies in metastatic esophageal cancer patients not receiving chemotherapy显示文摘BACKGROUND Palliative therapy has been associated with improved overall survival(OS)in several tumor types.Not all patients with metastatic esophageal cancer receive palliative chemotherapy,and the roles of other palliative therapies in these patients are limited.AIM To investigate the impact of other palliative therapies in patients with metastatic esophageal cancer not receiving chemotherapy.METHODS The National Cancer Database was used to identify patients between 2004-2015.Patients with M1 disease who declined chemotherapy and had known palliative therapy status[palliative therapies were defined as surgery,radiotherapy(RT),pain management,or any combination thereof]were included.Cases with unknown chemotherapy,RT,or nonprimary surgery status were excluded.Kaplan-Meier estimates of OS were calculated.Cox proportional hazards regression models were employed to examine factors influencing survival.RESULTS Among 140234 esophageal cancer cases,we identified 1493 patients who did not receive chemotherapy and had complete data.Median age was 70 years,most(66.3%)had a Charlson Comorbidity Index(CCI)of 0,and 37.1%were treated at an academic center.The majority(72.7%)did not receive other palliative therapies.On both univariate and multivariable analyses,there was no difference in OS between those receiving other palliative therapy(median 2.83 mo,95%CI:2.53-3.12)vs no palliative therapy(2.37 no,95%CI:2.2-2.56;multivariable P=0.290).On univariate,but not multivariable analysis,treatment at an academic center was predictive of improved OS[Hazard ratio(HR)0.90,95%CI:0.80-1.00;P=0.047].On multivariable analysis,female sex(HR 0.81,95%CI:0.71-0.92)and non-black,other race compared to white race(HR 0.72,95%CI:0.56-0.93)were associated with reduced mortality,while South geographic region relative to West region(HR 1.23,95%CI:1.04-1.46)and CCI of 1 relative to CCI of 0(HR 1.17,95%CI:1.03-1.32)were associated with increased mortality.Higher histologic grade and T-stage were also associated with worse OS(P<0.05).CONCLUSION Palliative therapies other than chemotherapy conferred a numerically higher,but not statistically significant difference in OS among patients with metastatic esophageal cancer not receiving chemotherapy.Quality of life metrics,inpatient status,and subgroup analyses are important for examining the role of palliative therapies other than chemotherapy in metastatic esophageal cancer and future studies are warranted. | Sungjin Kim Timothy P DiPeri Michelle Guan Veronica R Placencio-Hickok Haesoo Kim Jar-Yee Liu Andrew Hendifar Samuel J Klempner Ryan Nipp Alexandra Gangi Miguel Burch Kevin Waters May Cho Joseph Chao Katelyn Atkins Mitchell Kamrava Richard Tuli Jun Gong | 2020 | World Journal of Gastrointestinal Surgery2020，12，9： | 0 |
