概括

本案例研究突出了一个罕见的晚期结肠直肠癌 (CRC) 病例,该病例呈现出高的人类胆管性腺激素 (hCG) 和α-胎蛋白 (AFP) 水平,通常在生殖细胞瘤中见到. 这位年轻女性的异常瘤标志物配置推迟了诊断,强调了在瘤学中需要更广泛的差异诊断.

科学领域:

在瘤学瘤学.
生物化学生物化学
病理学病理学病理学

背景情况:

瘤标志物 (TM) 对于癌症管理至关重要,但异常呈现会使诊断复杂化.
人类胆管性淋巴激素 (hCG) 和α-胎蛋白 (AFP) 通常与生殖细胞瘤有关,而不是结直肠癌 (CRC).
在生育年龄的女性中hCG升高可能被错误地归因于怀孕,可能延迟癌症诊断.

研究的目的:

报告一种罕见的第四阶段结直肠癌 (CRC) 病例,同时表达hCG和AFP.
讨论CRC中非典型瘤标志物配置文件所带来的诊断挑战.
突出高hCG对女性非妊娠性恶性瘤诊断的潜在影响.

主要方法:

一位41岁的女性患有快速进展的第四期CRC病例报告.
对血清瘤标志物水平的分析,包括hCG,AFP,CA 19-9,CEA和CA 72-4.
放射性评估用于疾病进展的分期和监测.

主要成果:

患者呈现IV期CRC,而标准CRC标志物 (CA 19-9,CEA) 则略微升高.
血清中hCG (β-hCG) 的自由β亚单元和AFP的水平显著升高,模仿生殖细胞瘤标志物.
异型标志物概况最初表明未知位置的怀孕,延迟了CRC诊断.

结论:

在CRC中,β-hCG和AFP的同时表达是罕见的,并且与瘤的攻击性行为和不良预后有关.
在生育年龄的妇女中升高的β-hCG需要仔细解释,以避免误诊非孕期癌症.
需要进一步的研究来阐明hCG和AFP在CRC诊断,监测和预后中的作用,特别是在早期发病的情况下.

Patient-derived Orthotopic Xenograft Models for Human Urothelial Cell Carcinoma and Colorectal Cancer Tumor Growth and Spontaneous Metastasis

This protocol describes the generation of patient-derived orthotopic xenograft models by intra-vesically instilling high-grade urothelial cell carcinoma cells or intra-rectally injecting colorectal cancer cells into non-obese diabetic/severe combined immunodeficiency (NOD/SCID) mice for primary tumor growth and spontaneous metastases under the influence of lymph node stromal cells, which mimics the progression of human metastatic...

Establishment of a Co-culture System of Patient-Derived Colorectal Tumor Organoids and Tumor-Infiltrating Lymphocytes (TILs)

The protocol describes a method for creating a patient-derived colorectal cancer (CRC) organoid model co-cultured with tumor-infiltrating lymphocytes (TILs) to study their interactions and therapeutic potential. This model provides a preclinical platform to explore immune responses in the tumor microenvironment and to predict the efficacy of TIL-based therapy for personalized CRC...

Orthotopic Implantation of Patient-Derived Cancer Cells in Mice Recapitulates Advanced Colorectal Cancer

This protocol describes the orthotopic implantation of patient-derived cancer cells in the cecum wall of immunodeficient mice. The model recapitulates advanced colorectal cancer metastatic disease and allows for the evaluation of new therapeutic drugs in a clinically relevant scenario of lung and liver...

Isolation of Circulating Tumor Cells in an Orthotopic Mouse Model of Colorectal Cancer

We describe the establishment of orthotopic colorectal tumors via injection of tumor cells or organoids into the cecum of mice and the subsequent isolation of circulating tumor cells (CTCs) from this model.

Labeling of Breast Cancer Patient-derived Xenografts with Traceable Reporters for Tumor Growth and Metastasis Studies

We describe a method for stable labeling of patient-derived xenografts (PDXs) with lentiviral particles expressing green-fluorescent protein and luciferase reporters. This method allows for tracking the growth of PDXs at the primary site, as well as detecting spontaneous and experimental metastases using in vivo imaging...
