  • Background: Early detection of hepatocellular carcinoma using serological markers with better sensitivity and specificity than alpha fetoprotein (AFP) is needed. Aims: The aim of this study was to evaluate the diagnostic value of serum sICAM-1, ${\beta}$-catenin, IL-8, proteasome and sTNFR-II in early detection of HCC. Materials and Methods: Serum levels of IL-8, sICAM-1, sTNFR-II, proteasome and ${\beta}$-catenin were measured by ELISA assay in 479 serum samples from 192 patients with HCC, 96 patients with liver cirrhosis (LC), 96 patients with chronic hepatitis C (CHC) and 95 healthy controls. Results: Serum levels of proteasome, sICAM-1, ${\beta}$-catenin and ${\alpha}FP$ were significantly elevated in HCC group compared to other groups (P-value<0.001), where serum level of IL-8 was significantly elevated in the LC and HCC groups compared to CHC and control groups (P-value <0.001), while no significant difference was noticed in patients with HCC and LC (P-value=0.09). Serum level of sTNFR-II was significantly elevated in patients with LC compared to HCC, CHC and control groups (P-value <0.001); also it was significantly higher in HCC compared to CHC and control groups (P-value <0.001). ROC curve analysis of the studied markers between HCC and other groups revealed that the serum level of proteasome had sensitivity of 75.9% and specificity of 73.4% at a cut-off value of $0.32{\mu}g/ml$ with AUC 0.803 sICAM-1 at cut off value of 778ng/ml, the sensitivity was 75.8% and the specificity was 71.8% with AUC 0.776. ${\beta}$-catenin had sensitivity and specificity of 70% and 68.6% respectively at a cut off value of 8.75ng/ml with an AUC of 0.729. sTNFR-II showed sensitivity of 86.3% and specificity of 51.8% at a cut off value of 6239.5pg/ml with an AUC of 0.722. IL-8 had sensitivity of 70.4% and specificity of 52.3% at a cut off value of 51.5pg/ml with AUC 0.631. Conclusions: Our data supported the role of proteasome, sICAM-1, sTNFR-II and ${\beta}$-catenin in early detection of HCC. Also, using this panel of serological markers in combination with ${\alpha}FP$ may offer improved diagnostic performance over ${\alpha}FP$ alone in the early detection of HCC.

  • 목적 : 간암을 대상으로 한 고식적인 방사선치료가 아닌 정위방사선치료에 대한 보고는 매우 드물다. 이에 저자들은 원발성 간암환자들을 대상으로 정위방사선치료에 대한 예비결과를 알아보고자 하였다. 대상 및 방법 : 1999년 7월부터 2000년 3월까지 성모병원 치료방사선과에서 두개외 종양으로 정위방사선치료를 33명의 환자들에서 시행하였으며 그중 13명의 원발성 간암환자들을 대상으로 하였다. 대상환자들의 성별은 남자가 12명, 여자가 1명이었으며 연령분포은 $44\~66$세(중앙값:59세)였고 종양의 크기는 $10\~825\;cc$ (평균 : 185 cc)였다. 정위방사선치료는 1회 $3\~5\;Gy$$90\%$의 등선량 곡선에 기준하여 주 3-5회씩, $2\~3$주 동안 조사선량의 범위는 $30\~50\;Gy$이고 중앙선량은 50 Gy였다. 결과 : 추적관찰기간은 $3\~13$개월이었다(중간추적관찰기간: 8개월). 정위방사선치료 후 전체 환자에서 완전관해 $7.7\%$, 부분관해 $v$, 미세관해 $30.8\%$, 무반응 $7.7\%$였으며 국소제어율(완전관해+부분관해)은 $61.5\%$였다. 혈청 AFP의 치료 전과 치료 후 수치의 변화를 비교한 결과, 전체환자 중 $92.3\%$에서 AFP이 감소하였다. 치료에 따른 부작용은 소화장애가 $84.6\%$, 경한 오심이 $69.2\%$, 일시적인 간 기능의 저하가 $15.4\%$, 미열이 $7.7\%$에서 나타났으나 치명적인 부작용은 없었다. 결론 : 원발성 간암에 대한 정위방사선치료를 시행한 결과 비교적 안전하고 효과적인 치료방법이었다. 그러나 새로운 치료방법으로서 검증하기 위해서는 보다 많은 환자와 장기적인 추적관찰이 필요하리라고 사료된다.
