ABSTRACT

After the introduce of new treatment options is always important to see how the results of the registered studies will be putted into routine clinical practice. Clinical studies help to assess the efficacy and safety of therapy and to conduct the objective comparison of the current standard of treatment. However, it is impossible to take into account all the variety of situations that oncologists can face in their daily work. Nowadays, the use of targeted therapy in the presence of the specific genetic disorders, in particular, driver mutations in the epidermal growth factor receptor (EGFR) gene, is an integral part of the management of patients with advanced non-small cell lung cancer (NSCLC). The first EGFR tyrosine kinase inhibitors (TKIs) have significantly changed our possibility of the treatment in this group of patients, and today we are already using the third-generation EGFR TKIs. The review analyzes the experience of using the third-generation EGFR TKIs – osimertinib, through the prism of questions, asking by the practitioners: evaluation of the efficacy of treatment in routine practice, the management of difficult patients, in particular, the patients with bone and brain metastases, the patients with multiple primary tumors, the management tactics of patient taking into account the COVID-19 pandemic and related treatment interruptions. The literature and international experience review is completed by clinical cases from different regions of the Russian Federation. © 2022 Consilium Medikum. All Rights Reserved.

ABSTRACT

An immune checkpoint blockade with mAbs to PD-1 and PD-L1 is an expanding therapeutic option for mNSCLC patients. This treatment strategy is based on the use of mAbs able to restore the anti-tumor activity of intratumoral T cells inhibited by PD-1 binding to PD-L1/2 on tumor and inflammatory cells. It has been speculated that a chronic status of systemic inflammation as well as the immunosenescence physiologically occurring in elderly patients may affect the efficacy of the treatment and the occurrence of irAEs. We performed a multi-institutional retrospective study aimed at evaluating the effects of these mAbs (nivolumab or atezolizumab) in 117 mNSCLC patients younger (90 cases) and older (27 cases) than 75 years in correlation with multiple inflammatory parameters (NLR, CRP, ESR, LDH and PCT). No differences were observed when the cohorts were compared in terms of the frequency of PFS, OS, inflammatory markers and immune-related adverse events (irAEs). Similarly, the occurrence of irAEs was strictly correlated with a prolonged OS survival in both groups. On the contrary, a negative correlation between the high baseline levels of inflammatory markers and OS could be demonstrated in the younger cohort only. Overall, PD-1/PD-L1-blocking mAbs were equally effective in young and elderly mNSCLC patients; however, the detrimental influence of a systemic inflammation at the baseline was only observed in young patients, suggesting different aging-related inflammation immunoregulative effects.
