对46例疑诊为卵巢恶性肿瘤患者进行了腹水或肿瘤组织的染色体和细胞学检查、血清与欧立许醛试剂的显色反应和血清乳酸脱氢酶测定。在此46例中,32例最后确诊为卵巢恶性肿瘤,其余均证实为盆腔良性病变。染色体、细胞学、血清显色反应和血清乳酸脱氢酶的诊断准确率分别为86.96%、82.61%、70.0%和64.26％。分析表明染色体检查最为可靠,且如染色体和细胞学检查同为阳性时,卵巢癌的诊断即可确立。 The chromosomal and cytological examination of ascites or tumor tissue in 46 suspected ovarian cancer patients was performed. The chromogenic reaction of serum with orol aldehyde reagent and serum lactate dehydrogenase were measured. In this 46 cases, 32 cases were finally diagnosed as ovarian cancer, the rest were confirmed as pelvic benign lesions. The diagnostic accuracy of chromosome, cytology, serum chromogenic reaction and serum lactate dehydrogenase were 86.96%, 82.61%, 70.0% and 64.26%, respectively. Analysis shows that the most reliable chromosomal examination, and as both chromosomal and cytology tests are positive, the diagnosis of ovarian cancer can be established.
