Abstract
This study investigated clinicopathological features of patients with recurrence of metachronous multicentric occurrence by comparison with patients with recurrence due to metastasis. In 177 patients, recurrences after curative surgical treatment were classified into recurrence due to metastasis according to criteria based on imaging findings. This group consisted of 35 patients. Among the rest of the patients, 59 underwent fine needle biopsies for recurrent tumor and, in these patients, a classification of recurrence of metachronous multicentric occurrence was made based on the histological findings of primary and recurrent tumor. This group consisted of 33 patients. The estimated incidence for recurrence of metachronous multicentric occurrence was 44.8% to total total patients. Metachronous multicentric occurrence frequently developed in patients with anti-HCV antibody and an early stage of primary tumor. In 80% of the patients who had recurrent tumor of multicentric origin, the recurrence developed within 3 postoperative years. The survival rate in patients with metachronous multicentric occurrence was significantly higher than that in patients with recurrence due to metastasis. Conclusively, the incidence of patients with recurrence of metachronous multicentric occurrence was high, but the prognosis for these patients was significantly better than that for patients with recurrence due to metastasis.
