years in patients <55 years of age, 4 (3.2-4.9)
years in patients aged ≥55 years (p=0.450).
The median DFS was 4.0 (0.1-7.9) years in
patients <65 years of age, 4.5 (1.9-7.2) years
in patients aged ≥65 years (p=0.951). There
was no statistically significant difference
between the groups in terms of median OS and
DFS.
The median DFS was 5.9 (3.7-8.1) years in
male patients and 2.2 (1.2-3.2) years in
females (p=0.349). The median OS was 4.1

When the patients were divided into two
groups according to tumor location, median
OS could not be reached in the 2/3 anterior
tumors of the tongue, while the median OS
was 6.9 (2.7-9.8) years in the 1/3 posterior
tumors of the tongue (p=0.046) (Figure-1).
While the median DFS could not be reached
in the anterior 2/3 anterior tumors of the
tongue, the median DFS was 3.8 (1.0-6.7)
years in the 1/3 posterior tumors of the tongue
(p=0.073). While the median OS was 7.2 (6.8-
7.6) years in those who did not receive
adjuvant therapy, it did not reach the median
in those who received adjuvant therapy (RT or
CRT) (p=0.877). While the median DFS was
6.5 (0.2-13.2) years in those who did not
receive adjuvant therapy, it was 3.9 (1.7-6.1)
years in those who received adjuvant therapy
(RT or CRT) (p=0.317).
While the median OS was 3.1 (0.5-5.8) years
in smokers, the median OS could not be
reached in non-smokers (p=0.019) (Figure-2).
While the median OS was 1.6 (0.9-2.2) years
in the group of patients with ECOG PS of 2,
the median OS could not be reached in
