滋养细胞肿瘤,包括葡萄胎,侵蚀性葡萄胎和绒毛膜癌,是人体的一种非常奇特的肿瘤,它除具有一般肿瘤的特点外,尚具以下一些特点: 1.这类肿瘤绝大部分继发于妊娠之后,它的组织来源是胚外层,即滋养层,这和其他肿瘤来自胚胎组织完全不同。 2.这类肿瘤的细胞含有男方的成分。因此,从免疫角度看,是一种同种异体移植,具有高度的抗原性,但不受宿主的排斥。 3.这类肿瘤生长极快,即使是良性葡萄胎也具有入侵宿主的能力,有潜在恶性。而绒毛膜癌恶性程度则很高,很早就可以通过血液而转移至全身,破坏力极强。病人一旦发病,对生命威胁很大,多数在一年内死亡。 4.这类肿瘤产生的绒毛促性腺激素(hCG),可 Trophoblastic tumors, including hydatidiform mole, invasive hydatidiform mole and choriocarcinoma, are a very unique type of cancer in the body. In addition to the general characteristics of tumors, they have the following features: 1. The vast majority of these tumors Secondary to pregnancy, its tissue originates from the extraembryonic layer, the trophoblast, which is completely different from other tumors coming from embryonic tissue. 2. The cells of this kind of tumor contain the ingredients of the man. Therefore, immunologically, it is an allograft that is highly antigenic but not host-specific. 3. Such tumors grow extremely fast, even the benign mole also has the ability to invade the host, potentially malignant. The choriocarcinoma is highly malignant, very early can be transferred to the body through the blood, extremely destructive. Once the patient’s illness, life-threatening, most died within a year. 4. These tumors produce villus gonadotropin (hCG), can
