Purpose: With the increase in the average life expectancy, the elderly population continues to increase rapidly. However, no consensus has been reached on the feasibility for surgical resection due to the high morbidity and mortality rate after surgical treatment in elderly patients caused by aging and underlying diseases.
Methods : This study was performed with patients aged 80 years and older. The subjects were classified into 2 groups as follows: the surgical resection group consisting of 61 patients, and the conservative treatment group consisting of 39 patients suitable for curative resection.
Results : Mean age and clinical stages in the conservative treatment group were higher than those in the surgical resection group. There was no significant difference in sex, location of the lesion, histological type, or underlying disease. The mean survival time of surgical resection group and conservative treatment group was respectively 52.1 ± 2.66 months and 37.1 ± 5.08 months (P < 0.05) for clinical stage 1 disease, 41.7 ± 5.16 months and 22.4 ± 6.07 months (P = 0.004) for stage 2 disease, and 31.7 ± 9.37 months and 10.6 ± 1.80 months (P = 0.049) for stage 3 disease. However, as for the extent of lymph node resection for the different stages, we observed no significant difference between the 2 groups.
Conclusion : Surgical resection in all clinical stages, except stage 4, showed a higher survival rate than conservative treatment. To minimize postoperative surgery complications, limited lymph node dissection should also be considered.
