Abstract:
Patients with locally advanced rectal cancer who undergo neoadjuvant chemoradiotherapy may achieve pathological complete response (pCR). The incidence of recurrence is low among patients with pCR, there is still a lack of consensus on postoperative treatment and follow-up strategy. This review summarizes the recurrence patterns of patients with pCR, including distant metastasis rate, characteristics of distant metastasis time and location, local recurrence rate, and local recurrence time. The aim is to provide reference for the postoperative treatment and follow-up strategy of patients with pCR. Patients with pCR have a low recurrence rate, with infrequent local recurrence. Distant metastasis is the most common recurrence pattern, primarily in the lung and secondly in the regional lymph node. The time of recurrence is delayed which suggests the need for appropriate adjustments to follow-up strategy, extending the follow-up period, and placing emphasis on monitoring sites prone to recurrence.
