The aim of this study was to describe the ultrasonographic and Doppler flow attributes of granulosa cell tumors (GCT) of the ovary and to compare these attributes to those of epithelial tumors of the ovary. Among 13,475 gynecological patients who were scanned in our ultrasound unit between 1992 and 1996, seven patients had GCT. The final diagnosis was confirmed, postoperatively, by pathologic examination and by applying the WHO classification. The ultrasonographic findings of the GCT patients were compared to those recorded in a second group of 29 patients who had been diagnosed with epithelial tumor of the ovary. The sonographic appearance of GCT of the ovary was semi-solid and the endometrium was thick in six of the seven patients. Doppler flow studies of vessels within or in the contour of the lesions showed the resistive index (RI) to be 0.448 +/- 0.018. The epithelial tumors had a similar appearance and flow pattern except for the presence of ascites in one-third of the patients. Ultrasound scanning, including color Doppler flow, did not contribute data that could assist in differentiating between GCT and epithelial tumors of the ovary.

Paraneoplastic cerebellar degeneration heralding fallopian tube adenocarcinoma.

The objective of this paper is to describe an 81-year-old woman with subacute cerebellar degeneration due to fallopian tube adenocarcinoma. Serum anti-Yo antibodies were used to screen for pelvic malignancy. Their presence led to a meticulous search, which included bilateral salpingoophorectomy. Subsequently an occult fallopian tube adenocarcinoma was discovered. This case report highlights the diagnostic value of antineuroneal antibodies in females with subacute neurologic impairment in the form of paraneoplastic syndrome.

Comparing the genetic changes detected in the primary and secondary tumor sites of ovarian cancer using comparative genomic hybridization.

Our objective was to compare the genetic abnormalities in the primary tumors of epithelial ovarian cancer and their associated secondary peritoneal implants using comparative genomic hybridization (CGH). CGH was performed on seven apparent stage III ovarian serous cancer cases. Dissected tissue samples from the primary tumor and from the metastatic peritoneal implant were obtained at initial surgical staging and analyzed in each case. We used CGH as this technique allows the entire genome of the tumor to be examined simultaneously for chromosomal imbalances without the need for tissue culture or targeting of specific loci. The chromosomal abnormalities detected in the distinct sites were then reviewed and compared. CGH studies were successful in all 14 samples from the seven patients. The analysis revealed chromosomal aberrations in six patients with certain repeated changes as amplification of 1q, 2p, 2q, 3q, 6q, 8q, and 12p and underrepresentation of 18q and X chromosomes. Comparing the genomes of the primary tumors with the metastatic samples showed four cases with a balanced metastatic CGH profile while the primary site was aberrant. Greater chromosomal complexity associated with the primary site was detected in two other patients. In one case, both primary and secondary sites had no detectable chromosomal imbalances. The cytogenetic patterns in six of the seven primary tumors showed complex karyotypic changes, unlike the inconsistent findings that were associated with the secondary sites. The chromosomes of the secondary sites expressed either normal genomes or fewer genetic aberrations. Such genomic heterogeneity between the primary and secondary sites may indicate that the secondary peritoneal implants are de novo carcinogenesis occurrences. The results may support the concept that at least part of advanced ovarian cancer is a multicentric disease in the early stages. Further genetic studies are needed to reassess this assumption.
