The aim of our study was to determine the effect of homologous recombination deficiency (HRD) on prognosis and efficacy of platinum-based chemotherapy in patients with pancreatic cancer (PC). We performed PubMed and Embase database queries. We included 4 studies into the meta-analysis and 16 studies in the systematic review. Our systematic analysis showed that the average weighted median overall survival (OS) in patients with HRD with advanced PC was 19.8 and 15.6 months in patients without HRD. With platinum-based chemotherapy, the average weighted median OS in patients with HRD was 23.8 and 17.1 months in patients without HRD. Without platinum-based chemotherapy, the average weighted median OS in patients with HRD was 8.3 and 12.0 months in patients without HRD. For resected PC, our meta-analysis demonstrated that HRD status did not affect the prognosis (HR 1.03, 95% CI 0.46 to 2.33), but results were rather heterogeneous (I2=83%, p=0.003). Our systematic analysis showed that the average weighted median OS in patients with HRD was 34.6 and 27.0 months in patients without HRD. With platinum-based chemotherapy, the average weighted median OS in patients with HRD was 46.1 and 36.3 months in patients without HRD. Without platinum-based chemotherapy, the average weighted median OS in patients with HRD was 24.2 and 42.9 months in patients without HRD. Results of our meta-analysis and systematic review support the idea of platinum use in patients with HRD both in resected and metastatic PCs, although a randomised trial is warranted to make a more reliable conclusion.PROSPERO registration numberCRD42019121914.
Background. One of the priorities of health care is the balance between the financial resources and the availability of effective medical care. The current approach of access to cancer medicines limits the timeliness and availability of treatment. At the same time, financial support from the government provides great costs on cancer drugs. However, these great costs are not rational.Objective: to assess the financing needs of the complete transfer of financial support of medical care in the field of oncology to the Compulsory Health Insurance (CHI) system by means of optimizing the functions of the day hospital.Material and methods. The achievement of the goal is planned to be reached by eliminating the unusual functions of oncological day hospital. We analyzed the regulatory legal documents regulating drug care and drug provision in the Russian Federation, data from depersonalized (anonymized) registers of the structure of hospitalizations in a day hospital for 2021. The methods of expert assessments, mathematical modeling, as well as literature data analysis were used. The study developed a model for assessing the need to finance the full transfer of medicine provision to the CHI system, including taking into account the hidden deficit.Results. The total amount of funds released from the reduction of irrational hospitalizations in day hospital conditions amounted to 2.08% of the funding level of the analyzed schemes. Taking into account the data of hospitalizations in oncological day hospital for 2021, the number of irrational hospitalizations in case of transfer of selected schemes to the outpatient stage will decrease by 16.1%. The transfer of all the medicine therapy to financing from the CHI funds will require significant additional budget expenditures in the amount of 62.5 billion rubles or 2.65% of the total costs of the State Guarantees Program for Provision of Free Medical Care to Citizens.Conclusion. Despite the rationality of the proposed changes in the field of improving access to medicine provision concerning cancer drugs and the identified justifications for changing the distribution of financial resources within the State Guarantees Program, there are difficulties. In order to solve this problem, a coordinated consideration of potential strategies to address the access to cancer medicines is needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
