科学领域:
- 在瘤学瘤学.
- 胃肠病学 胃肠病学
- 病理学 病理学 病理学
背景情况:
- 神经内分泌的分化在结直肠癌 (CRC) 中很常见.
- 在缺乏典型神经内分泌形态的CRC中表达synaptophysin (Syn) 的临床意义尚不清楚.
研究的目的:
- 研究表达Syn.表达CRC的临床病理和分子特征.
- 评估Syn表达对患者生存的预后影响.
主要方法:
- 对663个常规CRC进行了同步免疫组织化学.
- 分析了临床病理学数据,分子标志物和生存率 (OS,DFS).
- 合成表达的CRC与传统的CRC和罕见的神经内分泌瘤 (MiNENs) 相比较.
主要成果:
- 合成表达 (≥30%) 在4.1%的CRC中被发现,与右结肠部位,第二级内淋巴细胞和BRAF V600E突变相关.
- 合成表达率≥30%是整体存活 (OS) 和无病存活 (DFS) 的独立负预后因素.
- 与糟糕的OS相关的因素包括年龄,晚期和Syn表达;明显的周围瘤淋巴细胞与较长的OS相关.
结论:
- 传统CRC中的同步表达与OS和DFS的恶化有关.

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
