Background: Peritoneal washing cytology (PWC) that shows the microscopic intra-peritoneal spread of gynaecologic cancers is not used in staging but is known as prognostic factor and effective in planning the intensity of the therapy. False negative or false positive results clearly affect the ability to make the best decision for therapy. In this study we assessed levels of tumour markers, carcinoembryonic antigen (CEA), cancer antigen 125 (CA-125) and carbohydrate antigen (CA19-9), in peritoneal washing fluid to establish any possible contribution to the peritoneal washing cytology in patients operated for gynaecologic cancer. Materials and Methods: Preoperative tumour markers were studied in serum of blood samples obtained from the patients for preoperative evaluation of a gynaecologic operation. In the same group peritoneal tumour markers were studied in the washing fluid obtained for intraoperative cytological evaluation. Results: This study included a total of 94 patients, 62 with malignant and 32 with benign histopathology. The sensitivity of the cytological examination was found to be 21% with a specificity of 100%. When evaluated with CEA the sensitivity of the cytological examination has increased to 37%. Conclusions: In addition to examination of PWC, the level of CEA, a tumour marker, in peritoneal washing fluid can make a diagnostic contribution. Determining the level of CEA in peritoneal washing fluid will be useful in the management of gynaecologic cancers.

Background: Intraperitoneal spread of gynecologic cancers is a major cause of mortality and morbidity and often presents with malignant ascites. Microscopic tumor spread can be demonstrated by a peritoneal wash cytology and help assess the prognosis of the disease. In our study, the roles of paraoxonase and ceruloplasmin, measured in peritoneal washing fluid of patients operated for gynecologic pathologies in differential diagnosis was investigated. Materials and Methods: Patients operated for malign or benign gynecologic pathologies in Antalya Education and Research Hospital Gynecology Clinic between 2010-2012 were included in the study. Samples were obtained during surgery. Results: A statistically significant difference was detected between patients with benign and malign diseases with regards to PON1 levels measured in peritoneal washing fluid (p:0.044), the average values being $64.2{\pm}30.8$ (Range 10.8-187.2) and $41.4{\pm}21.4$ (Range 10.4-95.5), respectively. No significant variation was evident for ceruloplasmin. Conclusions: Paraoxonase levels measured in peritoneal washing fluid may contribute to the differentiation of malign-benign diseases in gynecologic pathologies.

목적: 위암 환자에서 복강 내 파종은 대부분 장막을 침범한 원발성 암에서 떨어져 나온 복강 내 유리 암세포에 의해 이루어지는 것으로 가장 흔한 재발의 형태이다. 수술 중 이러한 유리 암세포의 존재를 직접 또는 간접적으로 확인할 수 있는 방법이 있다면 위암의 치료 전략을 정하는데 유용할 것이다. 이에 수술을 시행 받은 위암 환자를 대상으로 복강 세척액에서 CEA와 CA19-9의 검출 정도와 종양의 침윤도, 림프절 전이 및 병기 등과의 연관성을 알아보고자 연구를 시행하였다. 대상 및 방법: 2004년 5월부터 2006년 1월까지 건양대학교병원 외과에서 위암을 진단받고 수술을 시행한 130명의 환자를 대상으로 하였고, 모든 환자에서 복강 세척액을 채집하여 CEA, CA19-9를 측정하였다. 위의 비선암종 환자 14명을 대조군으로 하여 복강 세척액을 분석하였다. 결과: 위암 환자의 복강 CEA, CA19-9의 측정치는 종양의 침윤도, 림프절 전이 및 병기와 상관 관계가 있었으며(P<0.05) 복강 CEA 측정치는 비선암종 환자군과도 유의한 차이를 보였다. 결론: 복강 CEA, CA19-9의 증가는 TNM 병기와 부분적으로 평균치의 차이가 있고 복강 CEA는 다른 측정치에 비해 가치 있는 복막 전이 예측인자로서의 가능성을 확인하였다.
