One-year COVID-19 outcomes on the oncology care patient pathway: Results of a French descriptive, cross-sectional comprehensive study (ONCOCARE-COV).

BACKGROUND: The COVID-19 pandemic led to a widely documented disruption in cancer care pathway. Since a resurgence of the pandemic was expected after the first lockdown in France, the global impact on the cancer care pathway over the year 2020 was investigated. AIMS: This study aimed to describe the changes in the oncology care pathway for cancer screening, diagnosis, assessment, diagnosis annoucement procedure and treatment over a one-year period. MATERIALS & METHODS: The ONCOCARE-COV study was a comprehensive, retrospective, descriptive, and cross-sectional study comparing the years 2019 and 2020. All key indicators along the cancer care pathway assessing the oncological activity over four periods were described. This study was set in a high-volume, public, single tertiary care center divided in two complementary sites (Reims University Hospital and Godinot Cancer Institute, Reims, France) which was located in a high COVID-19 incidence area during both peaks of the outbreak. RESULTS: A total of 26,566 patient's files were active during the year 2020. Breast screening (-19.5%), announcement dedicated consultations (-9.2%), Intravenous and Hyperthermic Intraoperative Intraperitoneal Chemotherapy (HIPECs) (-25%), and oncogeriatric evaluations (-14.8%) were heavily disrupted in regard to 2020 activity. We identified a clear second outbreak wave impact on medical announcement procedures (October, -14.4%), radiotherapy sessions (October, -16%), number of new health record discussed in multidisciplinary tumor board meeting (November, -14.6%) and HIPECs (November, -100%). Moreover, 2020 cancer care activity stagnated compared to 2019. DISCUSSION: The oncological care pathway was heavily disrupted during the first and second peaks of the COVID-19 outbreak. Between lockdowns, we observed a remarkable but non-compensatory recovery as well as a lesser impact from the pandemic resurgence. However, in absence of an increase in activity, a backlog persisted. CONCLUSION: Public health efforts are needed to deal with the consequences of the COVID-19 pandemic on the oncology care pathway.

Penetration rate of anti-TNF biosimilars and savings at 5 years after their introduction in French hospitals.

OBJECTIVE: Since the expiry of the patents on originator anti-TNF agents in Europe, France has authorized the sale of biosimilars. The penetration rate of anti-TNF agents and their biosimilars, and the cost savings driven by the introduction of biosimilars appears to vary widely. This study aimed to describe the market share of anti-TNFs and their biosimilars, and the cost savings generated by the introduction of biosimilars in French hospitals 5 years ago. METHODS: The pharmaceutical component of the French national uniform hospital discharge data set database (PMSI) was used to study sales of infliximab, etanercept and adalimumab originators and biosimilars, and to estimate cost savings generated by the introduction of biosimilars onto the market, using the historical tariffs of the originators. RESULTS: The penetration rate of anti-TNF biosimilars in France in 76% for infliximab, 74% for etanercept and 77% for adalimumab. In 2020, Inflectra® (41%) was the Remicade® biosimilar with the highest sales volume, while Erelzi® (57%) and Amgevita® (64%) were the most widely sold biosimilars of Enbrel® and Humira® respectively. In terms of cost savings since the launch of biosimilars, overall, for all biosimilars taken together, over the 5-year period, a total of 824 million Euro was saved, in relation to the historical tariffs of the originators. CONCLUSIONS: This study shows firstly that the penetration rate of anti-TNF biosimilars in France 5 years after their launch is close to 80%. Secondly, we show that the cost savings generated by the use of biosimilars to anti-TNF agents exceed 820 million Euro over 5 years.

Reports of sexual disorders related to serotonin reuptake inhibitors in the French pharmacovigilance database: an example of underreporting.

BACKGROUND: Depressive disorders and use of antidepressants are associated with adverse effects on sexual function. In pharmacoepidemiological studies, sexual disorders are reported by more than 50 % of patients taking serotonin reuptake inhibitors (SRIs). OBJECTIVE: The aim of this study was to determine the reporting rate of sexual disorders in association with SRIs, and to investigate the association between reported cases and the use of SRIs. METHODS: All cases of adverse drug reactions (ADRs) involving sexual disorders, spontaneously reported to the French Pharmacovigilance Database from 1 January 1985 to December 2009, were reviewed. Cases of sexual disorders in SRI users were described. We calculated the rate of reported sexual disorders as a percentage of the total ADRs reported for each drug. The association between reported cases and the use of SRIs was assessed using reporting odds ratios (ROR) with 95 % confidence intervals (CIs). RESULTS: A total of 11,863 ADRs in association with SRIs were collected, of which 98 (0.83 %) were spontaneous reports of sexual disorders. Subjects were, on average, 45.0 ± 10.6 years of age and mainly male. Sexual disorders were associated with the use of SRI antidepressants (ROR 4.47; 95 % CI 3.61-5.53), milnacipran (ROR 11.72; 95 % CI 5.79-23.72), fluvoxamine (ROR 6.91; 95 % CI 3.79-12.58), paroxetine (ROR 5.54; 95 % CI 3.92-7.83), venlafaxine (ROR 3.50; 95 % CI 1.93-6.36), fluoxetine (ROR 3.46; 95 % CI 2.26-5.29), citalopram (ROR 2.69; 95 % CI 1.28-5.67) and sertraline (ROR 2.49; 95 % CI 1.03-6.01). CONCLUSION: It is likely that there are instances of underreporting, particularly for ADRs that are embarrassing to talk about spontaneously. Despite the likely underreporting of this well-described adverse effect, this case/non-case study performed in a large national pharmacovigilance database confirms the existence of the risk of sexual disorders associated with SRIs, and is an example of the lack of sensitivity of spontaneous notification to measure ADRs. Minimization of antidepressant-induced sexual dysfunction could be an important factor to avoid unsuccessful treatment. Physicians should advise their patients on the possible sexual adverse effects.
