Abstract
BRCA1 and BRCA2 are onco-suppressor genes involved in the DNA repair mechanism. The presence of BRCA1/2 mutations confers a higher risk of developing several cancer types. To date, the FDA approved various PARP inhibitors to treat selected BRCA1/2 mutated oncologic patients. At first, PARP inhibitors were approved for patients with ovarian and breast cancers, and subsequently for metastatic pancreatic adenocarcinoma and metastatic castration-resistant prostate cancer after the treatment with chemotherapy. The current guidelines for BRCA testing are very heterogeneous between the different types of tumors regarding the diagnostic algorithm and the type of sample to analyze, such as the blood for the germline mutations and the tumoral tissue for the somatic mutations. Few data have currently been described regarding the detection of BRCA1/2 somatic mutations in formalin-fixed paraffin-embedded (FFPE) samples. In this review, we propose an overview of the BRCA mutations in FFPE samples of several cancers, including breast, ovarian, fallopian tube, primary peritoneal, prostate, and pancreatic cancer. We summarize the types and the frequency of BRCA mutations, the guidelines approved for the test, the molecular assays used for the detection and the PARP inhibitors approved for each tumor type.

Implementation of preventive and predictive BRCA testing in patients with breast, ovarian, pancreatic, and prostate cancer: a position paper of Italian Scientific Societies. ESMO Open 2022; 7:100459. [PMID: 35597177 PMCID: PMC9126927 DOI: 10.1016/j.esmoop.2022.100459] [Citation(s) in RCA: 26] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 02/22/2022] [Accepted: 03/02/2022] [Indexed: 12/11/2022] Open
Abstract
Constitutional BRCA1/BRCA2 pathogenic or likely pathogenic variants (PVs) are associated with an increased risk for developing breast and ovarian cancers. Current evidence indicates that BRCA1/2 PVs are also associated with pancreatic cancer, and that BRCA2 PVs are associated with prostate cancer risk. The identification of carriers of constitutional PVs in the BRCA1/2 genes allows the implementation of individual and family prevention pathways, through validated screening programs and risk-reducing strategies. According to the relevant and increasing therapeutic predictive implications, the inclusion of BRCA testing in the routine management of patients with breast, ovarian, pancreatic and prostate cancers represent a key requirement to optimize medical or surgical therapeutic and prevention decision-making, and access to specific anticancer therapies. Therefore, accurate patient selection, the use of standardized and harmonized procedures, and adherence to homogeneous testing criteria, are essential elements to implement BRCA testing in clinical practice. This consensus position paper has been developed and approved by a multidisciplinary Expert Panel of 64 professionals on behalf of the AIOM–AIRO–AISP–ANISC–AURO–Fondazione AIOM–SIAPEC/IAP–SIBioC–SICO–SIF–SIGE–SIGU–SIU–SIURO–UROP Italian Scientific Societies, and a patient association (aBRCAdaBRA Onlus). The working group included medical, surgical and radiation oncologists, medical and molecular geneticists, clinical molecular biologists, surgical and molecular pathologists, organ specialists such as gynecologists, gastroenterologists and urologists, and pharmacologists. The manuscript is based on the expert consensus and reports the best available evidence, according to the current eligibility criteria for BRCA testing and counseling, it also harmonizes with current Italian National Guidelines and Clinical Recommendations. The rapid technologic and medical progress on BRCA-related cancers produced a clinical need for BRCA testing optimization. To incorporate BRCA testing in the routine management is a key requirement to help medical or surgical decision-making Standardized procedures and harmonized testing criteria are needed to implement BRCA testing in clinical practice. Adequate training and qualification for multidisciplinary team members are crucial for the success of the patient care path.

Mol Oncol 2021; 16:1591-1607. [PMID: 34854226 PMCID: PMC8978517 DOI: 10.1002/1878-0261.13149] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 11/02/2021] [Accepted: 11/30/2021] [Indexed: 02/06/2023] Open
Abstract
Poly[ADP‐ribose] polymerase (PARP) inhibitors can block DNA single‐strand damage repair and subsequently increase double‐stranded breaks (DSBs) by reducing the activity of the PARP1 protease and by preventing the PARP1 protein from dissociating from chromatin. Tumors with the BRCA mutation are particularly sensitive to PARP inhibitors. So far, PARP inhibitors (Olaparib) have been used to treat pancreatic cancer patients with BRCA mutation. However, these patients are prone to PARP inhibitor resistance. Our previous studies suggest that fructose‐1,6‐bisphosphatase 1 (FBP1) is responsible for the sensitivity to various anticancer agents, such as gemcitabine or mitogen‐activated protein kinase kinase (MEK) inhibitors. In this study, we demonstrate that FBP1 regulates the sensitivity to PARP inhibitors in pancreatic cancer. Then, we showed that nuclear FBP1 is responsible for this process by interacting with DNA (cytosine‐5)‐methyltransferase 1 (DNMT1) and trapping PARP1 in chromatin. Moreover, we revealed that ubiquitin carboxyl‐terminal hydrolase 7 (USP7) binds to and induces the deubiquitination of FBP1, which prevented FBP1 from translocating to the nucleus. Finally, we demonstrated that USP7 inhibitors enhanced the antitumor effect of PARP inhibitors in an FBP1‐dependent manner. Collectively, our results identify a novel USP7–FBP1–DNMT1 signaling axis in pancreatic cancer, which might indicate that USP7 inhibitors and PARP inhibitors might have more powerful antitumor effects than PARP inhibitors alone in pancreatic cancer patients.

Impact of Endoscopic Ultrasound-Guided Tissue Acquisition on Decision-Making in Precision Medicine for Pancreatic Cancer: Beyond Diagnosis. Diagnostics (Basel) 2021; 11:diagnostics11071195. [PMID: 34209310 PMCID: PMC8307595 DOI: 10.3390/diagnostics11071195] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 06/21/2021] [Accepted: 06/22/2021] [Indexed: 02/07/2023] Open
Abstract
Precision medicine in cancer treatment refers to targeted therapy based on the evaluation of biomarkers. Although precision medicine for pancreatic cancer (PC) remains challenging, novel biomarker-based therapies, such as pembrolizumab, olaparib, and entrectinib, have been emerging. Most commonly, endoscopic ultrasound-guided tissue acquisition (EUS-TA) had been used for the diagnosis of PC until now. However, advances in EUS-TA devices and biomarker testing, especially next-generation sequencing, have opened up the possibility of sequencing of various genes even in limited amounts of tissue samples obtained by EUS-TA, and identifying potential genetic alterations as therapeutic targets. Precision medicine benefits only a small population of patients with PC, but biomarker-based therapy has shown promising results in patients who once had no treatment options. Now, the role of EUS-TA has extended beyond diagnosis into decision-making regarding the treatment of PC. In this review, we mainly discuss tissue sampling by EUS-TA for biomarker testing and the current status of precision medicine for PC.
