Abstract

Background: Few reports have investigated genetic alterations between patients with early and late recurrence following curative surgery for colorectal cancer (CRC).

Methods: A total of 1227 stage I-III CRC patients who underwent curative resection were included retrospectively. Among them, 236 patients had tumor recurrence: 139 had early (<2 years after surgery) and 97 had late (≥2 years after surgery) recurrence. Clinicopathological features and genetic alterations were compared between the two groups.

Results: Compared to those with late recurrence, patients with early recurrence were more likely to have advanced pathological node (N) categories; tumor, node, metastasis (TNM) stages; adjuvant chemotherapy treatment; liver metastases; APC mutations; and worse five-year overall survival rates. Patients with right-sided colon cancer were more likely to develop early recurrence than were those with left-sided colon cancer or rectal cancer. Regarding rectal cancer, patients with early recurrence were more likely to be at advanced pathological N categories and TNM stages than those with late recurrence. Multivariate analysis revealed old age, early recurrence, multiple-site recurrence, and BRAF and NRAS mutations to be independent prognostic factors.

Conclusion: CRC patients with early recurrence have a worse OS rate and more APC mutations than those with late recurrence.

Keywords: colorectal cancer; early recurrence; genetic alteration; late recurrence; prognostic factor.

Five-year OS rates were significantly lower in CRC patients with early recurrence than in those with late recurrence (38.2% vs. 65.9%, p < 0.001). For right-sided colon cancer, five-year OS rates were significantly lower in CRC patients with early recurrence than in those with late recurrence (29.7% vs. 80.8%, p = 0.004). For left-sided colon cancer, five-year OS rates were not significantly different between CRC patients with early recurrence and those with late recurrence (47.0% vs. 64.9%, p = 0.134). For rectal cancer, five-year OS rates were significantly lower in CRC patients with early recurrence than in those with late recurrence (39.1% vs. 62.0%, p = 0.030). The survival curves are shown as follows: (A) all CRC patients, (B) right-sided colon cancer patients, (C) left-sided colon cancer patients, and (D) rectal cancer patients.

Five-year postrecurrence survival rates were not significantly different between CRC patients with early recurrence and those with late recurrence (32.4% vs. 32.8%, p = 0.802). For right-sided colon cancer, five-year postrecurrence rates were not significantly different between patients with early recurrence and patients with late recurrence (24.9% vs. 33.7%, p = 0.366). For left-sided colon cancer, five-year postrecurrence rates were not significantly different between patients with early recurrence and patients with late recurrence (40.6% vs. 29.9%, p = 0.401). For rectal cancer, five-year postrecurrence rates were not significantly different between patients with early recurrence and patients with late recurrence (32.0% vs. 32.4%, p = 0.594). The survival curves are shown as follows: (A) all CRC patients, (B) right-sided colon cancer patients, (C) left-sided colon cancer patients, and (D) rectal cancer patients.
