Prognostic factors in hereditary breast cancer: A review by Ziske Maritska, Sarmoko

“…However, the risk of developing other malignancies, such as ovarian cancer and melanoma, remains elevated in BRCA mutation carriers. Studies show a significant variation in survival rates, with BRCA mutation carriers having lower overall survival compared to non-carriers. …”

A comprehensive comparison of PARP inhibitors as maintenance therapy in platinum-sensitive recurrent ovarian cancer: a systematic review and network meta-analysis by Shiya Ji, Lu Chen, Yebo Yu, Xupeng Chen, Liwen Wei, Lili Gou, Cheng Shi, Susu Zhuang

“…Results Six randomized controlled trials were examined and the four PARPis (olaparib, niraparib, rucaparib and fuluzolparib) have been found to significantly increase the PFS in entire population as well as in subgroups of HRD and BRCAm (BRCA mutation). Only olaparib demonstrated a substantial improvement in OS compared to placebo in entire population (hazard ratio [HR] 0.73; 95% confidence interval [CI] 0.60–0.90), as well as in the subgroup of BRCAm. …”

Homologous recombination deficiency test validation in patients with high-grade advanced ovarian cancer by Angelica Nogueira Rodrigues, Andreza Karine de Barros Almeida Souto, Diocésio Alves Pinto de Andrade, Larissa Müller Gomes, Sandra Satie Koide, Renata de Godoy e Silva, Bruno Batista de Souza, Juliana Doblas Massaro, Andréia Cristina de Melo, Andrea Morais Borges, Camila Giro, Carlos Augusto Vasconcelos de Andrade, Cesar Martins da Costa, Daniel Luiz Gimenes, Eduardo Caminha Bandeira de Mello, Fernanda Cesar de Oliveira, Frederico Müller de Toledo Lima, Gabriel Lima Lopes, Gustavo de Oliveira Bretas, Gustavo Guerra Jacob, Herika Lucia da Costa Silva, Juliana Ferrari Notaro, Lara Ladislau Alves, Marcos Veloso Moitinho, Mirian Cristina da Silva, Roberto Abramoff, Thais Amaral da Cunha Rauber, Rodrigo Dienstmann, Fernanda Christtanini Koyama

“…BackgroundAlong with BRCA mutation status, homologous recombination deficiency (HRD) testing is a prognostic and predictive biomarker for poly-ADP-ribose polymerase (PARP) inhibitor therapy indication in high-grade epithelial ovarian, fallopian tube, or peritoneal cancer. …”

Low dose DNA methyltransferase inhibitors potentiate PARP inhibitors in homologous recombination repair deficient tumors by Romain Pacaud, Scott Thomas, Sibapriya Chaudhuri, Ann Lazar, Luika A. Timmerman, Pamela N. Munster

“…In animal studies, our BRCA-engineered hypomorphs and several independent PDX models with clinically relevant BRCA mutations were acutely more vulnerable to this drug combination. …”

Tousled-like kinase loss confers PARP inhibitor resistance in BRCA1-mutated cancers by impeding non-homologous end joining repair by Min-ah Kim, Banseok Kim, Jihyeon Jeon, Jonghyun Lee, Hyeji Jang, Minjae Baek, Sang-Uk Seo, Dongkwan Shin, Anindya Dutta, Kyung Yong Lee

“…Given that DSBs are highly cytotoxic, PARP inhibitors (PARPi), a prominent class of anticancer drugs, are designed to target tumors with HR deficiency (HRD), such as those harboring BRCA mutations. However, many tumor cells acquire resistance to PARPi, often by restoring HR in HRD cells through the inactivation of NHEJ. …”
