Abstract
BACKGROUND

Esophageal cancer (EC) often occurs in the elderly, with approximately 33% of patients aged ≥ 75 years at the time of diagnosis.

AIM

To evaluate the prognostic factors for radiotherapy (RT) in elderly patients with unresectable EC.

METHODS

We retrospectively analyzed the clinical characteristics, toxic reactions, and survival information of EC patients aged ≥ 75 years who underwent intensity-modulated RT at Lu’an Hospital of Anhui Medical University between January 2016 and September 2023. Kaplan-Meier analysis was used to draw the overall survival (OS) curves, and Cox regression analysis was employed to evaluate the influence of various clinical factors on the prognosis.

RESULTS

A total of 139 patients were enrolled. The median follow-up time was 52.0 months. The median OS was 20.0 months. The 1-year, 2-year, 3-year, and 5-year OS rates were 69.8%, 38.7%, 28.2%, and 17.5%, respectively. Univariate analysis showed that age, radiation dose, and chemotherapy had no significant impact on prognosis. Multivariate analysis indicated that clinical stage [III-IVa vs I-II, hazard ratio (HR) = 2.421, 95% confidence interval (CI): 1.242-4.718, P = 0.009; IVb vs I-II, HR = 4.222, 95%CI: 1.888-9.438, P < 0.001), Charlson comorbidity index (CCI) (0 vs ≥ 1, HR = 1.539, 95%CI: 1.015-2.332, P = 0.042), and nutritional risk screening 2002 (NRS2002) (< 3 vs ≥ 3, HR = 2.491, 95%CI: 1.601-3.875, P < 0.001) were independent prognostic factors for OS.

CONCLUSION

Our results suggest that CCI and NRS2002 were independent prognostic factors of OS for unresectable elderly EC patients undergoing RT. For elderly patients with EC, full attention should be given to biological age-related indicators, such as comorbidities and nutrition, when formulating treatment protocols. These factors should be considered in future clinical practice.

Core Tip: Esophageal cancer (EC) often occurs in the elderly, with approximately 33% of patients aged ≥ 75 years at the time of diagnosis. Since patients aged 75 years and above are often excluded from many clinical trials of EC, there is a lack of agreement regarding the prognosis and treatment of this population. We retrospectively analyzed the clinical characteristics, toxic reactions, and survival information of elderly patients with EC aged ≥ 75 years who received intensity-modulated radiotherapy. Our analysis aimed to evaluate the prognostic factors affecting overall survival. We found that the Charlson comorbidity index and nutritional risk screening 2002 were independent prognostic factors for overall survival. Our results suggest that when formulating treatment plans for elderly patients with EC, full attention should be given to age-related biological indicators such as comorbidities and nutrition.
