Safety and Efficacy of Transarterial Chemoembolization Combined With Immune Checkpoint Inhibitors and Tyrosine Kinase Inhibitors for Hepatocellular Carcinoma

PurposeTo explore the safety and efficacy of transarterial chemoembolization (TACE) in combination with immune checkpoint inhibitors (ICIs) and tyrosine kinase inhibitors (TKIs) for the treatment of unresectable hepatocellular carcinoma (uHCC).Materials and MethodsFrom August 2019 to July 2020, patients who received TACE combined with ICIs and TKIs were retrospectively analyzed. Treatment-related adverse events (AEs) were recorded. The Kaplan–Meier method was used to estimate time to progression (TTP) and progression-free survival (PFS).ResultsIn total, 31 patients with uHCC were included. Eleven patients were classified as BCLC-C. Nineteen patients had multiple lesions, and the cumulative targeted lesions were 69 mm (range, 21-170 mm) according to mRECIST. Twenty-nine (93%) patients experienced at least one AE during the treatment. Four (12.9%) patients developed AEs of higher grade (grade≥3). The objective response rate (ORR) and disease control rate (DCR) were 64.5% and 77.4%, respectively. The median time to response was 7 weeks (range, 4-30 w), and the duration of response was 17.5 weeks (range, 2-46 w). From the first ICIs, TTP and PFS were 6.5 months (95% CI, 3.5-11) and 8.5 months (95% CI, 3.5-NE), respectively.ConclusionsTACE combined with ICIs and TKIs shows an acceptable safety profile and considerable efficacy in patients with HCC.

On the role of autophagy in the progression of differentiated thyroid cancer (literature review)

The aim of the study was to analyze and summarize available literature data on the role of autophagy in thyroid cancer. Material and methods. We analyzed 34 publications available from pubmed and elibrary. Ru databases concerning thyroid cancer and autophagy. Results. The review discussed the role of autophagy in the progression of thyroid cancer. The development of autophagy-targeted therapy was shown can improve treatment for thyroid cancer. Differentiated thyroid cancer (dtc) is the most common endocrine malignancy. Treatment of dtc patients who are resistant to radioactive iodine therapy is a major challenge. Molecular targeted therapy using tyrosine kinase inhibitors significantly improves treatment outcomes. Conclusion. To enhance the therapeutic effect of treatment with multi-target tyrosine kinase inhibitors, as well as to overcome drug resistance, it is necessary to study the role of autophagy in the development and progression of thyroid cancer.

Optical spectra and conformation pool of tyrosine kinase inhibitor PD153035 using robust quantum mechanical conformation search

Tyrosine kinase inhibitors (TKIs) based on the quinazoline-aniline scaffold represent a significant class of small molecule drugs for diseases such as cancer. The present study applies the recently developed robust...
