| Popis: | This study was designed to elucidate the significance of preoperative computed tomography during arterial portography (CTAP) in surgical treatment of hepatocellular carcinoma (HCC). Eighteen patients with HCC whose minute lesions had been pointed out by CTAP preoperatively (CTAP positive group) were compared with another eight patients with HCC having postoperative recurrence in a region at where no tumors had been detected by preoperative CTAP (CTAP negative group) for preoperative location of tumor and postoperative pattern of recurrence. In the CTAP positive group, 11 patients had recurrence and the remaining seven patients had not. Disease-free periods up to recurrences were 8.7 months in an average in the 11 CTAP positive patients and 16.6 months in the CTAP-negative group, showing a significantly shorter interval in the CTAP positive patients. In recurred cases from the CTAP positive group, tumors identified by imaging procedures other than CTAP were solitary in four and multiple in seven cases, while all solitary in nonrecurred cases. In the recurred CTAP positive cases, actual recurrence occurred in the same segment where a tummor had been pointed out by CTAP alone in five out of six cases of solitary recurrenc; or involved the same segment where CTAP detected tumor (s) in four out of five cases of multiple recurrence. It is indicated that the possibility of postoperative recurrence of HCC is high in cases having minute lesions visualized by CTAP alone in addition to multiple lesions visualized by imaging procedures other than CTAP. We think that periodical imaging methods including CTAP are required for HCC patients. |
