Analysis of serum soluble interferon α/β receptor levels in patients with urological diseases

泌尿器科疾患における血清中可溶性インターフェロンα/βレセプターの意義

(Purpose)In order to define the clinical significance of serum soluble Interferon α/βreceptor(sIFN/α/βR)levels, we determined sIFNα/βR concentrations in serum of patients with urological benign and malignant diseases. (Materials and Methods)Serum sIFNα/βR levels were measured in normal control(n=22), patients with benign diseases(n=50)included urolithiasis(n=16), prostatic hypertrophy(n=13), and malignant diseases included bladder cancer(n=49), renal cell carcinoma(n=30)and prostate cancer(n=36)by the enzyme linked immunosolbent assay(ELISA)using monoclonal and pliyclonal antibodies. The levels of serum sIFNα/βR was correlated with the results of other hematoserological examinations, and clinical or pathological characters of each urological malignancies. (Results)The serum sIFNα/βR levels(pg/ml)of patients with urolithiasis(2,370.6±640.6, p=0.0002), benign prostatic hypertrophy(2,121.1±55.06, p=0.0103), bladder cancer(2,512.3±1,012.3,p=0.0006), renal cell carcinoma(2,686.4±1,510.9, p=0.0046), prostate cancer(3,188.7±1,788.0, P=0.0003)showed significantly higher values than those of controls(1,790.5±346.7). Moreover, we found statistically significant correlations among serum creatinine(Cr)levels and sIFNα/βR levels. However, there were no correlations between the sIFNα/βR levels and clinical stage, or histological grade in the patients with bladder cancer or prostate cancer, whenever the levels of sIFNα/βR were corrected by serum Cr levels. On the other hand, high level of corrected serum sIFNα/βR was observed in patients with high stage or high grade renal cell carcinoma, but not significant statistically. (Conclusion)Elevated serum sIFNα/βR was observed in patients with urological decease. Further examinations should be necessary to determine the clinical usefulness of serum sIFNα/βR.

(目的)泌尿器科疾患における可溶性インターフェロンα/βレセプター(soluble Interferon-α/βreceptor:sIFNα/βR)に関する検討はまだ十分なされていない．今回,ポリクローナル抗体およびモノクローナル抗体を用いたサンドイッチEnzyme Linked Immunosolbent Assay(ELISA)法による細胞膜外部分のsIFNα/βRの測定系が確立されたので,各種泌尿器科良性疾患,膀胱癌,腎細胞癌,前立腺癌の血清中sIFNα/βRを測定し臨床的意義について検討を行った．(対象と方法)健常コントロール22例,良性疾患50例(尿路結石症16例,前立腺肥大症13例,その他21例),膀胱癌49例,腎細胞癌30例,前立腺癌36例を対象として,血清中sIFNα/βR値をELISA法により測定した．臨床検査値との相関,各疾患群における血清中sIFNα/βR値の比較,さらには悪性腫瘍患者における臨床病理像との比較解析を行った．(結果)各疾患における血清中sIFNα/βR値(pg/ml)は,健常コントロール(1,709.5±346.7)に比し,尿路結石症(2,370.6±640.6,p=0.0002),前立腺肥大症(2,121.1±550.6,p=0.0103),膀胱癌(2,512.3±1,012.3,p=0.0006),腎細胞癌(2,636.4±1,510.9,p=0.0046),前立腺癌(3,188.7±1,788.0,p=0.0003)ともに,有意に高値を示した．各種血液学的検査結果との比較では,血清中クレアチニン値との相関が認められたが,その他の検査結果との相関は認めなかった．また,血清中sIFNα/βR値と膀胱癌および前立腺癌における臨床病理像との比較では,実測値および血清中クレアチニン値による補正値(Cr補正値)ともに有意な相関は認めなかった．一方,腎細胞癌では,進行例および異型度の強い症例においてCr補正値が高値を示したが,統計学的に有意ではなかった．(結論)血清中sIFNα/βR値は各種泌尿器科疾患において高値を示した．血清中sIFNα/βR値の臨床応用の可能性を評価するためには,今後さらに多数例における詳細な検討が必要と思われた．


The role of the activated form of matrix metalloproteinase-2 in urothelial cancer

To investigate the expression of matrix metalloproteinase-2 (MMP-2, reportedly associated with cancer cell invasion and metastasis in many human cancers) in urothelial tumours and thus define its role in this disease. Materials and methods The expression of both the activated form of MMP-2 and total MMP-2 (activated + latent form) was measured using gelatine zymography in tissue obtained surgically from 61 patients with urothelial cancer. The correlation between the level of the activated form of MMP-2 and clinical and histological variables was assessed. The expression of activated and total MMP-2 were significantly higher in invasive tumour tissue and both levels were correlated with histological grade. In particular, the level of activated MMP-2 was more closely correlated than that of total MMP-2 in invasive tumour tissue. Moreover, high levels of activated MMP-2 were strongly associated with shorter disease-specific survival (P = 0.0016). These findings suggest that activated MMP-2 plays a significant role in invasion of urothelial cancer and that the level of activated MMP-2 expression is a useful prognostic indicator.

Long-term recurrence-free survivor after laparoscopic removal of solitary adrenal metastasis from endometrial adenocarcinoma.

Solitary adrenal metastasis from endometrial adenocarcinoma is extremely rare. We report herein the case of a laparoscopically resected solitary adrenal metastasis originating from endometrial adenocarcinoma. The patient was a 55-year-old woman who had undergone total abdominal hysterectomy for stage IIIc endometrial carcinoma, followed by 7 courses of adjuvant chemotherapy comprising carboplatin and paclitaxel. However, the patient developed an isolated right adrenal metastasis 15 months postoperatively. The solitary adrenal metastasis (diameter, 5.7 cm) was removed laparoscopically. The patient has now been in good health without recurrence for 5 years and 7 months after laparoscopic surgery. To the best of our knowledge, this is the first case of solitary adrenal metastasis originating from endometrial adenocarcinoma that is controlled for the long term by successful laparoscopic resection.
