 Outcomes of Primary Surgical Cytoreduction in Patients with BRCA-associated High-grade Serous Ovarian Carcinoma

Objective

BRCA-associated and sporadic ovarian cancers have different pathologic and clinical features. Our goal was to determine if BRCA mutation status is an independent predictor of residual tumor volume following primary surgical cytoreduction.

Highlights

► Differences in the biology of BRCA-associated and sporadic ovarian cancers do not result in differences in primary surgical outcomes.
► The improved survival of BRCA-associated ovarian cancers is not confounded by differences in primary surgical outcome.

Abstract

Background
Alterations in telomere maintenance mechanisms leading to short telomeres underlie different genetic disorders of ageing and cancer predisposition syndromes. It is known that short telomeres and subsequent genomic instability contribute to malignant transformation, and it is therefore likely that people with shorter telomeres are at higher risk for different types of cancer. Recently, the authors demonstrated that the genes BRCA1 and BRCA2 are modifiers of telomere length (TL) in familial breast cancer. The present study analysed TL in peripheral blood leucocytes of hereditary and sporadic ovarian cancer cases, as well as in female controls, to evaluate whether TL contributes to ovarian cancer risk.

Methods
TL was measured by quantitative PCR in 178 sporadic and 168 hereditary ovarian cases (46 BRCA1, 12 BRCA2, and 110 BRCAX) and compared to TL in 267 controls.

Results
Both sporadic and hereditary cases showed significantly shorter age adjusted TLs than controls. Unconditional logistic regression analysis revealed an association between TL and ovarian cancer risk with a significant interaction with age (p<0.001). Risk was higher in younger women and progressively decreased with age, with the highest OR observed in women under 30 years of age.

Conclusion
These findings indicate that TL could be a risk factor for early onset ovarian cancer.
