We evaluated the relationship between IL-8 and prostate cancer (PCa) with emphasis on diagnosis, aggressiveness and prognosis.
MATERIALS & METHODS: Prostate-specific antigen (PSA) and serum IL-8 were collected from patients undergoing prostate biopsy. IL-8 expression was evaluated on immunohistochemistry with IL-8 labeling index. Complete follow-up of this cohort was achieved over a period of up to 6 years with continuous follow-up of PSA levels.
Among 135 patients, serum IL-8 level did not correlate to the diagnosis or aggressiveness of PCa. In 52 radical prostatectomy specimens, a higher IL-8 labeling index was detected in the tumor areas (0.4 ± 0.2 vs 0.33 ± 0.2; p = 0,007) but did not correlate to any of the prognostic markers: D'Amico classification (p = 0.52), Gleason score (p = 0.45), perineural (p = 0.83) and capsular invasion (p = 0.75). No correlation was found to PSA biochemical-free failure.
IL-8 serum level was not a significant predictor of diagnosis, aggressiveness or prognosis of PCa.
我们评估了白细胞介素-8（IL-8）与前列腺癌（PCa）之间的关系，重点关注诊断、侵袭性和预后。
收集接受前列腺活检患者的前列腺特异性抗原（PSA）和血清IL-8。通过IL-8标记指数对IL-8表达进行免疫组织化学评估。对该队列进行了长达6年的完整随访，并持续监测PSA水平。
在135例患者中，血清IL-8水平与PCa的诊断或侵袭性无关。在52例根治性前列腺切除术标本中，肿瘤区域检测到较高的IL-8标记指数（0.4±0.2对0.33±0.2；p=0.007），但与任何预后标志物均无相关性：D’Amico分级（p=0.52）、Gleason评分（p=0.45）、神经周围侵犯（p=0.83）和包膜侵犯（p=0.75）。与PSA无生化复发也无相关性。
IL-8血清水平不是PCa诊断、侵袭性或预后的重要预测指标。
