 Abstract
- Carcinosarcomas of the female genital tract have generally been regarded as a type of sarcoma. Recent studies, however, suggest the tumor may be more closely related to carcinoma and may represent metaplastic carcinoma in histogenesis. We analyzed clinicopathologic and immunohistochemical features of 10 carcinosarcomas to evaluate the relative importance of the carcinomatous and sarcomatous components in metastasis and recurrence. The primary tumor originated in the uterine body in seven cases, the uterine cervix in two and the ovary in one. Patient,s ages ranged from 54 to 71 years (mean, 64). The most common symptom of the uterine mass was vaginal bleeding. The median survival time was 21 months following diagnosis in five cases. Surgico-pathologic FIGO stages of five patients who received an operation were stage III and IV, but clinical FIGO stage of three patients (60%) among them were I. Lymphovascular invasions were identified in seven areas; five vascular invasion lesions showed the carcinomatous component alone, one the sarcomatous component alone, and remained one admixture of both components.
Metastatic and recurrent lesions to the paraaortic lymph node, ovary, pelvic wall, or vaginal vault showed characteristically carcinomatous component only.
Immunohistochemically, positive reactions for cytokeratin and epithelial membrane antigen were noted in the sarcomatous component of five cases. Vimentin positivity was detected in carcinomatous component of three cases. We conclude that the dominant element in carcinosarcomas of the female genital tract is the carcinomatous component. The survival rate of carcinosarcoma is extremely poor. The surgico-pathologic stage is better indicator of survival than the clinical stage. Immunohistochemical findings suggest that carcinosarcoma may represent a metaplastic carcinoma in histogenesis.

- OBJECTIVE: False negatives of cervical smears due to screening errors pose a significant and persistent problem.
AutoPap 300 QC System, an automated screening device, is designed to rescreen conventionally prepared Pap smears initially screened by cytotechnologists as normal. Clinical experience and sensitivity of the AutoPap 300 QC System were assessed and compared with current 10% random quality control technique.
MATERIALS AND METHODS: In clinical practice, a total of 18,592 "within normal limits" or "benign cellular changes" cases classified by The Bethesda System were rescreened by the AutoPap System. In study for sensitivity of The AutoPap System to detect false negatives, a total of 1,680 "within normal limits" or "benign cellular changes" cases were rescreened both manually and by the AutoPap System. The sensitivity of the AutoPap System to these false negatives was assessed at 10% review rate to compare 10% random manual rescreen.
RESULTS
In clinical practice, 38 false negatives were identified by the AutoPap System and we had achieved 0.2% reduction in the false negative rate of screening error. In study for sensitivity, 37 false negatives were identified by manual rescreening, and 23 cases(62.2%) of the abnormal squamous cytology were detected by the AutoPap System at 10% review rate.
CONCLUSONS: The AutoPap 300 QC System is a sensitive automated rescreening device that can detect potential false negatives prior to reporting and can reduce false negative rates in the laboratory. The device is confirmed to be about eight times superior to the 10% random rescreen in detecting false negatives.
