Saline infusion sonohysterography in endometrial cancer: assessment of malignant cells dissemination risk
Alcázar JL, Errasti T, Zornoza A.
To assess the risk of malignant cells dissemination in patients with endometrial cancer undergoing saline infusion sonohysterography (SIS).
Fourteen consecutive patients (mean age: 58.1 years, range: 41-74 years) diagnosed as having a clinical stage I endometrial carcinoma and scheduled for surgical staging were entered in this study. SIS was performed at the time of laparotomy just when the abdomen was opened and prior to the start of the surgical procedure. 10-20 mL of saline was infused. All fluid spilled from the fimbrial ends of the fallopian tubes was collected and analyzed for the presence or absence of malignant endometrial cells. Samplings were also taken from ascites, if found, or cytological washings, prior to and after SIS.
SIS could be satisfactorily performed in all patients. There was no spillage from either tube in nine patients. Mean fluid volume obtained from the other five patients was 4.4 mL. Cytologic analysis revealed the presence of malignant cells in the spilled fluid in one case (7.1%, one out of fourteen).
Our data show that a small but real risk of malignant cell dissemination exists in patients with endometrial carcinoma who undergo SIS.
