The early detection of ovarian cancer: from traditional methods to proteomics. Can we really do better than serum CA-125?

Ovarian cancer is the leading cause of death from gynecologic malignancy in the United States. More than 80% of patients present with advanced disease, with 5 year survival rates between 15% and 45%. In contrast, the survival rate for stage I disease, with malignancy confined to the ovary, is approximately 95%. Given the discrepancy in survival outcomes between early- and late-stage disease, strategies that would allow for the detection of ovarian cancer in its early stages would hold promise to significantly improve the mortality rate from ovarian cancer. Unfortunately, current screening methods for the detection of early stage ovarian cancer are inadequate. However, several recent proteomics-based biomarker discovery projects show promise for the development of highly sensitive and specific markers for gynecological malignancies, including ovarian cancer. In this review, we hope to provide an overview of the early detection ovarian cancer from traditional methods to recent promises in the proteomics pipeline.

Tattoo pigment lymphadenopathy mimicking metastasis in vulvar cancer.

BACKGROUND: Approximately 24% of American adults have tattoos. Studies of humans and mice demonstrate that tattoo pigment migrates to lymph nodes and can cause lymphadenopathy. CASE: A 32-year-old woman presented with a 6-cm vulvar mass and extensive bilateral inguinofemoral lymphadenopathy. Bilateral small tattoos were noted in the groins. Vulvar biopsy confirmed squamous cell carcinoma, and fine needle aspiration of the lymph nodes showed no evidence of malignancy. The patient underwent a radical hemivulvectomy and bilateral inguinofemoral lymphadenectomy. Both inguinal and femoral nodes were enlarged because of extracellular tattoo pigment and reactive follicular hyperplasia without any evidence of metastasis. CONCLUSION: This case emphasizes the need to consider tattoo pigment as a cause of lymphadenopathy in any patient with a regional tattoo.
