Abstract
Objectives: The prognoses of T1-2N0 and T1-2N1 colon cancer after curative surgery remain unclear. This study compared the prognoses of patients with T1-2N0 and T1-2N1 colon cancer after curative surgery.
Materials and methods: We retrospectively evaluated 307 consecutive patients with T1-2N0/1 colon cancer who underwent radical surgery at our hospital between January 2010 and December 2016. There were 266 patients with T1-2N0 colon cancer and 41 patients with T1-2N1 colon cancer. After excluding patients with <12 retrieved lymph nodes, 179 patients with T1-2N0 and 32 with T1-2N1 colon cancer were included in the cohort.
Results: Overall survival and disease-free survival did not differ between the T1-2N0 and T1-2N1 groups (p = 0.498 and p = 0.681, respectively). Overall survival and disease-free survival were not significantly different between the T1-2N1 + no chemotherapy and T1-2N1 + chemotherapy groups (p = 0.740 and p = 0.765, respectively). Additionally, overall survival and disease-free survival did not differ between the T1-2N0, T1-2N1 + no chemotherapy, and T1-2N1 + chemotherapy groups (p = 0.757 and p = 0.877, respectively), even after excluding patients with <12 retrieved lymph nodes.
Conclusions: T1-2N1 has a prognosis as good as that of T1-2N0 colon cancer after curative surgery. Moreover, further research is needed to investigate the efficacy of adjuvant FOLFOX chemotherapy in T1-2N1.
