Efficacy of Next-Generation EGFR-TKIs in Patients With Non-Small Cell Lung Cancer: A Meta-Analysis of Randomized Controlled Trials.
The efficacy of next-generation epidermal growth factor receptor-tyrosine kinase inhibitors in patients with advanced non-small cell lung cancer who have failed first-generation epidermal growth factor receptor-tyrosine kinase inhibitors still remains under investigation. ⋯ Next-generation epidermal growth factor receptor-tyrosine kinase inhibitors were shown to be the better agent to achieve higher response rate and longer progression-free survival in patients with non-small cell lung cancer as the later-line therapy for previously treated patients with first-generation epidermal growth factor receptor-tyrosine kinase inhibitors. Meanwhile, they did not achieve benefit in overall survival and safety compared with the chemotherapy group. Further research is needed to develop a database of all EGFR mutations and their individual impacts on the various treatments.

ALDH3B1 Is an Independent Prognostic Biomarker of Lung Adenocarcinoma.
Lung cancer is the leading cause of cancer-related death, and adenocarcinoma is the most common type of lung cancer. Although emerging evidence implicates the role of several aldehyde dehydrogenases in cancer progression, the expression and clinical significance of aldehyde dehydrogenase 3B1 in lung adenocarcinoma has never been studied. ⋯ Aldehyde dehydrogenase 3B1 was an independent prognostic biomarker of lung adenocarcinoma, indicating the unfavorable prognosis. Postoperative detection of aldehyde dehydrogenase 3B1 would help stratify the high-risk patients with lung adenocarcinoma and guide individual treatment.

ReviewArtificial Intelligence in Radiotherapy Treatment Planning: Present and Future.
Treatment planning is an essential step of the radiotherapy workflow. It has become more sophisticated over the past couple of decades with the help of computer science, enabling planners to design highly complex radiotherapy plans to minimize the normal tissue damage while persevering sufficient tumor control. As a result, treatment planning has become more labor intensive, requiring hours or even days of planner effort to optimize an individual patient case in a trial-and-error fashion. ⋯ In this review, the smart planning tools in current clinical use are summarized in 3 main categories: automated rule implementation and reasoning, modeling of prior knowledge in clinical practice, and multicriteria optimization. Novel artificial intelligence-based treatment planning applications, such as deep learning-based algorithms and emerging research directions, are also reviewed. Finally, the challenges of artificial intelligence-based treatment planning are discussed for future works.

Overexpression of miR-222-3p Promotes the Proliferation and Inhibits the Apoptosis of Diffuse Large B-Cell Lymphoma Cells via Suppressing PPP2R2A.
This study aimed to investigate the effects of microRNA-222-3p on activated B cell-like-type diffuse large B-cell lymphoma cells and the regulatory relationship between microRNA-222-3p and phosphatase 2 regulatory subunit B alpha. ⋯ MicroRNA-222-3p promoted the proliferation and invasion and inhibited the apoptosis of activated B cell-like-type diffuse large B-cell lymphoma cells through suppressing phosphatase 2 regulatory subunit B alpha expression.

Comparative StudyCalliSpheres Drug-Eluting Bead Transcatheter Arterial Chemoembolization Presents With Better Efficacy and Equal Safety Compared to Conventional TACE in Treating Patients With Hepatocellular Carcinoma.
The aim of this study was to compare the treatment response, survival, liver function, and adverse event incidence of drug-eluting bead transcatheter arterial chemoembolization using CalliSpheres microspheres with conventional transcatheter arterial chemoembolization in patients with hepatocellular carcinoma. Seventy-three patients with hepatocellular carcinoma who received drug-eluting bead transcatheter arterial chemoembolization (using CalliSpheres microspheres) or conventional transcatheter arterial chemoembolization treatment were consecutively enrolled. Treatment response was assessed by modified Response Evaluation Criteria in Solid Tumors at month 1/month 3/month 6; posttreatment, liver function indexes, and adverse events were recorded. ⋯ Meanwhile, most of the occurrences of abnormal liver function indexes were similar between 2 groups, whereas drug-eluting bead transcatheter arterial chemoembolization group had a higher percentage of patients with total bile acid ≥2 upper limit of normal compared to conventional transcatheter arterial chemoembolization group at month 1. Moreover, the adverse event incidences between 2 groups were similar. In conclusion, drug-eluting bead transcatheter arterial chemoembolization using CalliSpheres microspheres achieves better treatment response and progression-free survival while equal safety compared to conventional transcatheter arterial chemoembolization in patients with hepatocellular carcinoma.
