抽象的

背景與目的:我們研究了已實現乙型肝炎表面抗原 (HBsAg) 血清學清除的慢性乙型肝炎 (CHB) 患者發生肝細胞癌 (HCC) 和肝功能失代償的長期趨勢。

方法:在 2000 年 1 月至 2020 年 12 月期間清除 HBsAg 的所有成年 CHB 單一感染患者均使用香港全境數據庫進行識別。 HBsAg 血清清除前或隨訪時間少於 6 個月的肝移植和/或 HCC 患者被排除在外。 主要和次要終點分別是 HCC 和肝功能失代償。

結果:我們確定了 9,769 名 HBsAg 血清學清除的 CHB 患者(平均年齡 57 歲,60.0% 為男性,13.2% 為肝硬化); 大多數人在 HBsAg 消失時具有代償性肝功能。 在 4.6 (2.2-8.4) 年的中位隨訪(第 25-75 個百分位數)中,106 名 (1.1%) 患者發展為 HCC。 與未患 HCC 的患者相比,發生 HCC 的患者年齡較大,男性和肝硬化的可能性更大,並且在 HBsAg 消失時谷丙轉氨酶水平較高,血小板水平較低。 在 HBsAg 消失後的 0-7 年和 8-12 年內,HCC 的累積發病率保持穩定 (P=0.898)(粗略的年發病率下降:-0.04%,95% CI -0.13%-0.04%,P=0.265)。 此外,124/9,640 (1.3%) 名患者出現肝功能失代償。 HBsAg 消失後的前 7 年,肝功能失代償的累積發病率增長在 8-12 年內減緩 (P=0.009)(粗略的年發病率下降:-0.23%,95% CI -0.40% - -0.06%,P= 0.012)。 在多變量分析中,超過 7 年的 HBsAg 消失與肝失代償風險降低相關(調整後的亞分佈風險比 [aSHR] 0.55,95% CI 0.31-0.97,P=0.039),但與 HCC(aSHR 1.35,95% CI)無關 0.83-2.19,P=0.230)。

結論:HBsAg 消失後患者的 HCC 風險持續存在,而肝臟失代償的風險隨時間降低。

影響和意義:慢性乙型肝炎 (CHB) 患者在乙型肝炎表面抗原 (HBsAg) 血清學清除 12 年後仍有不可忽視的肝細胞癌 (HCC) 風險,尤其是在肝硬化患者中。 HBsAg 血清學清除後,發生肝功能失代償的風險會隨著時間的推移而降低。 在臨床實踐中,雖然清除 HBsAg 的 CHB 患者比那些仍處於慢性感染狀態的患者有更好的臨床結果,但對於 HBsAg 血清學清除後的肝硬化患者和非肝硬化患者的高危亞群,長期的 HCC 監測仍然是必要的。

關鍵詞:HBsAg 血清學清除; 肝臟失代償; 乙型肝炎病毒; 肝癌。

Abstract

Background & aims: We examined the long-term trend of incident hepatocellular carcinoma (HCC) and hepatic decompensation among chronic hepatitis B (CHB) patients who have achieved hepatitis B surface antigen (HBsAg) seroclearance.

Methods: All adult CHB monoinfected patients who cleared HBsAg between January 2000 and December 2020 were identified using a territory-wide database in Hong Kong. Patients with liver transplantation and/or HCC before HBsAg seroclearance or follow-up less than 6 months were excluded. The primary and secondary endpoints were HCC and hepatic decompensation respectively.

Results: We identified 9,769 CHB patients with HBsAg seroclearance (mean age 57 years, 60.0% male, 13.2% cirrhosis); most had compensated liver function at HBsAg loss. At a median (25th-75th percentile) follow-up of 4.6 (2.2-8.4) years, 106 (1.1%) patients developed HCC. Patients who developed HCC were older, more likely to be male and cirrhotic, and had higher alanine aminotransferase and lower platelets at the time of HBsAg loss than patients without HCC. The cumulative incidence of HCC remained steady in 0-7 and 8-12 years after HBsAg loss (P=0.898) (crude annual incidence drop: -0.04%, 95% CI -0.13%-0.04%, P=0.265). Moreover, 124/9,640 (1.3%) patients developed hepatic decompensation. The growth in cumulative incidence of hepatic decompensation decelerated in 8-12 years after the first 7 years of HBsAg loss (P=0.009) (crude annual incidence drop: -0.23%, 95% CI -0.40% - -0.06%, P=0.012). In multivariable analysis, HBsAg loss for over 7 years was associated with a reduced risk of hepatic decompensation (adjusted subdistribution hazard ratio [aSHR] 0.55, 95% CI 0.31-0.97, P=0.039) but not HCC (aSHR 1.35, 95% CI 0.83-2.19, P=0.230).

Conclusion: HCC risk persists in patients after HBsAg loss, whereas the risk of hepatic decompensation decreases over time.

Impact and implications: Patients with chronic hepatitis B (CHB) still have a non-negligible risk of hepatocellular carcinoma (HCC) after 12 years of hepatitis B surface antigen (HBsAg) seroclearance, especially among those with cirrhosis. The risk of developing hepatic decompensation decreases over time after HBsAg seroclearance. In clinical practice, although CHB patients who cleared HBsAg have a more favourable clinical outcome than those who remain chronically infected, long-term HCC surveillance would still be necessary for cirrhotic patients and high-risk subgroups of non-cirrhotic patients after HBsAg seroclearance.

Keywords: HBsAg seroclearance; hepatic decompensation; hepatitis B virus; liver cancer.
