Evaluation of efficacy of enhanced CT scanning in patients with primary liver cancer after TAEC
Objective To investigate the effect of enhanced CT scanning on primary liver cancer patients after TAEC.Methods Ninety-seven patients(108 lesions)with primary liver cancer admitted to the minimally invasive interven-tion department of our hospital from February 1,2020 to February 1,2023 were selected as the research objects.All pa-tients were treated with TAEC surgery,and underwent enhanced CT scanning and digital subtraction angiography(DSA)examination after surgery.With DSA diagnosis as the"gold standard",enhanced CT scanning technology was used to e-valuate the efficacy of interventional surgery in patients with primary liver cancer(PLC).The diagnostic accuracy,spe-cificity and sensitivity were analyzed to evaluate the application value of the technique.Results DSA showed 108 le-sions in 97 patients.Among them,47(43.92％)lesions were completely inactivated and 61(56.08％)lesions re-mained.Enhanced CT scan revealed 108 lesions in 97 patients.Among them,46(42.59％)lesions were completely inactivated and 62(57.41％)lesions remained.The accuracy,sensitivity,specificity and positive predictive value of enhanced CT scanning in the diagnosis of positive lesions in PLC patients after TAEC were 95.37％(103/108),96.72％(59/61),93.62％(44/47)and 95.16％(59/62)respectively.The negative predictive value was 95.65％(44/46).Compared with plain CT scan,enhanced CT scan significantly increased the diagnostic sensitivity and speci-ficity of lesion size and donor artery source in PLC patients after TAEC(P＜0.05).There was no significant difference between enhanced CT scan and DSA in the recurrence of PLC patients after TAEC(P＞0.05).Using DSA as the gold standard,the sensitivity and specificity of enhanced CT scanning for postoperative recurrence were 98.46％(64/65),97.67％(42/43),98.44％(63/64)and 95.45％(42/44)respectively.Conclusion Enhanced CT scan has high application value in the evaluation of primary liver cancer patients after TAEC.
