In 2011, a standard approach to the treatment of primary ovarian cancer (OC) included a cytoreductive surgery, which could be performed after 2–3 cycles of neoadjuvant chemotherapy, and chemotherapy consisting of platinum and taxanes. Such approach was provided for all patients, regardless of tumour histology and any molecular biological and genetic factors. The most complete picture of management and therapy of patients can be made using the treatment of a specific patient as an example. After application to the N.N. Blokhin National Medical Research Center of Oncology in 2011, the patient with OC received standard primary therapy and subsequent treatment of the recurrent disease, which was accompanied by various types of adverse events resulting in the poor quality of life for the patient. The data that some patients with OC have a BRCA1/2 mutation that is significant for prognosis and treatment came to hand later and, unfortunately, the awareness of a significant germinal BRCA1 mutation was of no use to the woman any longer. The life expectancy of this patient was 47 months. This is the average life expectancy for patients with stage IIIC OC. Major changes have been brought in the primary therapy of OC. If a diagnosis of low-grade IIIC ovarian adenocarcinoma was established in this patient today, needless to say that the BRCA1 mutation would be identified during the first-line chemotherapy, and in case of full or partial treatment effect, we would prescribe olaparib as maintenance therapy to the patient. Considering the fact that the median progression-free survival has not yet been achieved in the patients of SOLO-1 study, who received olaparib therapy, and is only approaching 54 months, it can be assumed that even the first relapse could not have developed in this patient.
