Abstract:
Objective:To retrospectively analyze the efficacy and safety of different radiotherapy doses in treating esophageal squamous carcinoma(ESCC)patients aged ≥80 years.Methods:This retrospective study collected clinical data from ESCC patients aged ≥80 years who underwent radiotherapy at the Fourth Hospital of Hebei Medical University from January 2016 to September 2021.Observation variables included overall survival(OS), progression free survival(PFS), complete response(CR), partial response(PR), stable disease(SD), progressive disease(PD), and adverse reactions.Survival rates were estimated using the Kaplan-Meier method and compared via log-rank tests.Cox regression models were employed for multivariate analysis.Results:A total of 165 patients who met the enrollment criteria were included in this study, including 88(88/165, 53.3%)males and 77(77/165, 46.7%)females, age 80 to 100 years(median age 83 years), 66 cases(66/165, 40.0%)in the radiotherapy dose ≥60 Gy group and 99 cases(99/165, 60.0%)in the <60 Gy group.Of the 165 patients, the effective rate was 71.5%(118/165).The median overall survival(OS)of the whole group was 19.0 months, The median Progression Free Survival(PFS)for the whole group was 13 months.The results showed that radiotherapy dose, lesion length, Nutritional Risk Index(NRI), eating condition, recurrence/progression and chemotherapy were factors influencing OS.The survival of patients in the ≥60 Gy group, ≤5 cm group, well-nourished group(NRI ≥45)group, soft diet and general diet group and combined chemotherapy group is better.Cox multivariate analysis revealed that radiotherapy, dose eating condition and the lesion length were independent prognostic factors for OS.The OS rate of the radiation therapy group with a dose of ≥ 60 Gy was better than that of the<60 Gy group( P=0.001), the OS of the general or soft diet group was better than that of the semi liquid or liquid diet group( P=0.008), and the OS of the lesion length ≤ 5 cm group was better than that of the>5 cm group( P=0.020).The incidence rates of radiation-induced esophagitis, myelosuppression, radiation pneumonia, and gastrointestinal reactions in the entire group were 60.0%(99/165), 12.1%(20/165), 22.4%(37/165), and 14.5%(24/165), respectively.51.5%(85/165)of the group experienced local recurrence, 10.3%(17/165)had distant organ metastasis, and 9.1%(15/165)had non regional lymph node metastasis.As of the follow-up date, there were a total of 99 deaths in the entire group. Conclusions:For patients aged 80 years or older with esophageal cancer, higher radiation doses, better feeding and nutritional status have more beneficial for prolonged survival.Local recurrence remains the main reason for treatment failure in elderly patients with esophageal cancer.
