The five-year survival rate of patients after curative resection of hepatocellular carcinoma (HCC) has been reported to be 30 to 50%, however the actual survival rate may be different. We analyzed the actual 5-year survival rate and prognostic factors after curative resection of HCC. Retrospective analysis was performed on 63 HCC patients who underwent curative resection from 1998 to 1999. A total of 63 cases were reviewed, consisting of 53 men and 10 women, with a median age of 49 years. These cases included all four pathologic T stages (pT stage) and had the following representation: stage 1 (1 case), stage 2 (17 cases), stage 3 (38 cases), and stage 4 (7 cases). In our study, the actual 5-year survival rate was 57.0% and the median survival time was 60 months. In addition, the patients in our study had an actual 5-year disease-free survival rate of 50.2% and a median disease-free survival time of 46 months. Thirty-one patients had recurrences, with a majority occurring within one year (65%). These patients with early recurrences had a poor actual 5-year survival rate of 5%. A univariate analysis showed that the prognostic factors influencing survival rate were the presence of satellite nodules, increased pT stage, HCC recurrence, and the time to recurrence (within one year). Interestingly, microvascular invasion made a difference in survival rate but was not statistically significant (p = 0.08). Furthermore, factors influencing the disease free survival rate include the presence of satellite nodules, microvascular invasion, and pT stage. Multivariate analysis identified pT stage as the only statistically related factor in determining the disease-free survival rate. The most important prognostic factor of HCC is recurrence. Moreover, the major risk factor for recurrence is an advanced pT stage. Therefore, performing prospective studies of postoperative adjuvant therapy is necessary to prevent recurrences after hepatic resection. Furthermore, active preventative treatment and early diagnosis of recurrences should be of the highest priority in the care of high-risk patient groups that have an advanced pT stage.
据报道,肝细胞癌(HCC)根治性切除术后患者的五年生存率为30%至50%,然而实际生存率可能有所不同。我们分析了HCC根治性切除术后的实际五年生存率及预后因素。对1998年至1999年接受根治性切除的63例HCC患者进行回顾性分析。共回顾63例病例,其中男性53例,女性10例,中位年龄49岁。这些病例涵盖了所有四个病理T分期(pT分期),具体分布如下:1期(1例)、2期(17例)、3期(38例)和4期(7例)。在我们的研究中,实际五年生存率为57.0%,中位生存时间为60个月。此外,我们研究中的患者实际五年无病生存率为50.2%,中位无病生存时间为46个月。31例患者出现复发,大多数在一年内复发(65%)。这些早期复发的患者实际五年生存率较差,为5%。单因素分析显示,影响生存率的预后因素包括卫星结节的存在、pT分期增加、HCC复发以及复发时间(一年内)。有趣的是,微血管侵犯对生存率有影响,但无统计学意义(p = 0.08)。此外,影响无病生存率的因素包括卫星结节的存在、微血管侵犯和pT分期。多因素分析确定pT分期是决定无病生存率的唯一具有统计学相关性的因素。HCC最重要的预后因素是复发。此外,复发的主要危险因素是pT分期进展。因此,开展术后辅助治疗的前瞻性研究对于预防肝切除术后复发是必要的。此外,在pT分期进展的高危患者群体的护理中,积极的预防性治疗和复发的早期诊断应是重中之重。
