Mean of CA 125 in making therapy decision in adnexal inflammatory tumors

Multiple alternative splicing markers for ovarian cancer

Intense efforts are currently being directed toward profiling gene expression in the hope of developing better cancer markers and identifying potential drug targets. Here, we present a sensitive new approach for the identification of cancer signatures based on direct high-throughput reverse transcription-PCR validation of alternative splicing events. This layered and integrated system for splicing annotation (LISA) fills a gap between high-throughput microarray studies and high-sensitivity individual gene investigations, and was created to monitor the splicing of 600 cancer-associated genes in 25 normal and 21 serous ovarian cancer tissues. Out of >4,700 alternative splicing events screened, the LISA identified 48 events that were significantly associated with serous ovarian tumor tissues. In a further screen directed at 39 ovarian tissues containing cancer pathologies of various origins, our ovarian cancer splicing signature successfully distinguished all normal tissues from cancer. High-volume identification of cancer-associated splice forms by the LISA paves the way for the use of alternative splicing profiling to diagnose subtypes of cancer.

High levels of CA125 (over 1,000 IU/ml) in patients with gynecologic disease and no malignant conditions: three cases and literature review

OBJECTIVE

To report the very high serum levels of CA125 in patients with benign gynecologic disease which manifests as pelvic mass.

METHODS

Clinical data of three cases with high levels of CA125 over 1,000 IU/ml and benign gynecologic conditions were gathered. in Vali-Asr hospital.

RESULTS

Three patients were scheduled for laparatomy as ovarian cancer and leiomyosarcoma. Histologic results after laparatomy showed uterine myoma in two patients and endometrioma in a third patient.

CONCLUSION

High levels of CA125 over 1,000 IU/ml, may be showed in other gynecologic conditions with no malignancy. So, other clinical and imaging data could be helpful for differential diagnosis of these patients.
