Background: In locally advanced esophageal cancer, neoadjuvant chemo-radiotherapy improves survival compared with surgery alone. In the Chemo-Radiotherapy for Oesophageal cancer followed by Surgery Study (CROSS), the median age was 60. However, 1/3 of patients diagnosed with esophageal cancer are over 70 years. The CROSS outcomes are therefore limited in its application to older patients. The objective of this study is to report and compare the outcomes and tolerability in elderly patients (≥70 years), who underwent neoadjuvant chemo-radiation for esophageal cancer with younger patients < 70 years. Methods: A retrospective analysis of patients treated with neoadjuvant chemo-radiation for esophageal cancer between 1^st January 2015 and 1^st January 2021 was completed. Baseline characteristics and haematological toxicities were reported. Pathological response was reported. Survival was estimated using the Kaplan-Meier method. Results: In total 105 patients were included; 35 (33%) were ≥ 70 years and 70 (67%) patients were < 70 years. In the elderly cohort, the median age was 75 (70-86) and the younger cohort median age was 60 (29-69). 73% of patients in each cohort were male. 31 (89%) of older adults experienced any grade of anaemia compared with 45 (64%) of the younger cohort. Only one patient experienced ≥ grade 3 anaemia in each cohort. 18(51%) and 33(47%) of older and younger patients respectively experienced any grade of neutropenia. 5(14%) older and 7(10%) younger patients experienced ≥ grade 3 neutropenia. 15(43%) and 43(61%) of older and younger patients experienced any grade of thrombocytopenia. No patients experienced ≥ grade 3 thrombocytopenia. 80% of the older and 86% of the younger cohort proceeded to surgery. 3(11%) and 17(29%) of the older and younger cohorts respectively who underwent surgery achieved a complete pathological response. There was no difference in overall survival (OS) between the cohorts (p=0.48). There was also no difference in progression free survival (PFS) between the cohorts. Conclusions: In conclusion, we confirm that neoadjuvant chemo-radiation is tolerable in patients ≥ 70 when compared with patients < 70 years. Both OS and PFS is similar in both cohorts. We recommend the use of neoadjuvant therapy in appropriately selected patients ≥ 70 years.
