Special Issue Information

Dear Colleagues, 

It is a pleasure to be Guest Editor for the upcoming Cancers Special Issue “BRCA Associated Cancers: Latest Predictive and Therapeutic Approaches”. The role of BRCA testing in the identification of an individual’s overall risk of developing certain cancer types, such as breast, ovarian, prostate and pancreatic cancer is widely recognized.

A plethora of clinical studies have presented various contributing factors to the higher prevalence of BRCA mutations in a population subset, such as personal or family history, ethnic background and early onset of cancer, where BRCA testing is recommended, also contributing to the therapeutic efficacy that treatment schemes such as PARP inhibitors could offer. This Special Issue highlights the role of BRCA testing from early risk assessment to options for treatment management, with the latest results of ongoing clinical studies being presented, demonstrating the clinical potential of various treatment options for BRCA-associated tumours, while investigating factors that contribute to the therapeutic response with significant future clinical relevance if integrated into the current clinical guidelines.

Dr. Melpomeni Kalofonou

Background/Objectives: Ductal carcinoma in situ (DCIS) is the most common non-invasive form of breast cancer. It is not clear to what extent DCIS is a part of the hereditary breast/ovarian cancer syndrome caused by BRCA1/2 mutations. Therefore, we investigated the association of BRCA1/2 mutations in patients with DCIS and assessed their impact on survival. Methods: We studied 564 Polish women with DCIS for six alleles in BRCA1 (c.181T>G, c.5266dupC, c.4035delA, c.3700_3704del5, c.68_69del and c.5251C>T) and four in BRCA2 (c.658_659del, c.3847_3848del, c.5946del and c.7913_7917del). To investigate the association of BRCA1/2 founder mutations with DCIS risk, we tested 4702 controls as a reference. To analyze survival, mutation carriers were followed for an average of 110 months. Results: A BRCA1 mutation was present in seven (1.24%) cases and in twenty-two (0.47%) controls (OR = 3.27, 95%CI 1.36 to 7.87, p = 0.01). A BRCA2 mutation was present in eight (1.42%) cases versus six (0.13%) controls (OR = 11.3, 95%CI 3.9 to 32.6, p < 0.0001). Three of the fifteen cases with BRCA1/2 mutations developed invasive ipsilateral or contralateral breast cancer, on average 6 years from the diagnosis of DCIS. There were no deaths reported among the 15 mutation carriers with DCIS. Conclusions: DCIS is a part of the hereditary breast/ovarian cancer syndrome caused by BRCA1/2 mutations. Women with DCIS should receive genetic counseling and testing for BRCA1/2 mutations. BRCA1/2 mutations may predispose women to a better DCIS prognosis, but further studies are needed. Full article

Background: Identifying patients with gBRCAm is crucial to facilitate screening strategies, preventive measures and the usage of targeted therapeutics in their management. This review examines the evidence for the latest predictive and therapeutic approaches in BRCA-associated cancers. Clinical Description: Data supports the use of adjuvant olaparib in patients with gBRCAm high-risk HER2-negative breast cancer. In advanced gBRCAm HER2-negative breast cancer, the PARPis talazoparib and olaparib have demonstrated benefit over standard chemotherapy. In ovarian cancer, olaparib, niraparib or rucaparib can be used as monotherapy in frontline maintenance. Olaparib and bevacizumab as a combination can also be used as frontline maintenance. In the relapsed platinum-sensitive setting, olaparib, niraparib and rucaparib are effective maintenance options in BRCAm patients who are PARPi naive. Both olaparib and rucaparib are effective options in BRCAm metastatic castrate-resistant prostate cancer (mCRPC). Evidence also exists for the benefit of PARPi combinations in mCRPC. In metastatic pancreatic cancer, olaparib can be used in gBRCAm patients who are responding to platinum chemotherapy. However, there may be a development of PARPi resistance. Understanding the pathophysiology that contributes to such resistance may allow the development of novel therapeutics. Combination therapy appears to have promising results in emerging trials. Seeking avenues for subsidised genetic testing can reduce the total costs of cancer management, leading to improve detection rates. Conclusion: Identifying breast, ovarian, pancreatic and prostate cancer patients with gBRCAm plays a crucial predictive role in selecting those who will benefit significantly from PARPi therapy. The use of PARPi in gBRCAm HBOC-related cancers has resulted in significant survival benefits. Beyond BRCA1/2, HRR gene assessment and the consideration of other cancer predisposition syndromes may allow more patients to be eligible for and benefit from targeted therapies. Full article
