RESUMO
Radiation-induced skin damage (RID) is the most prevalent, significant side effect of radiotherapy (RT). Nearly 95% of patients experience moderate to severe skin reactions after receiving radiation therapy. However, criteria for acute radiation dermatitis (ARD) treatment remain unavailable. Topical agents with anti-inflammatory properties may protect the skin and facilitate tissue regeneration in patients with RID. Many of these topical agents function through nuclear factor kappa B pathway regulation. They either reduce the levels of inflammatory factors or elicit anti-inflammatory properties of their own, thus preventing oxidative stress and inflammatory responses and thus enabling RID prevention and management. Herein, we explore the 25 topical agents investigated for RID prevention and management thus far and evaluate their mechanisms of action. These agents include 11 natural agents, 3 miscellaneous agents, 9 topical nonsteroidal agents, and 2 topical corticosteroids.
RESUMO
Non-small-cell lung cancer (NSCLC) has an extremely low 5-year survival rate, with the only effective treatment being immunoradiotherapy (iRT). Here, we review the progress of clinical research on iRT for non-small-cell lung cancer (NSCLC) over 2018-2023, as well as the future directions. We first discuss the synergistic mechanisms of iRT, reflected in three aspects: immune regulation of RT, RT-activated immune-related pathways, and RT-related immune sensitization. iRT may include either external-beam or stereotactic-body RT combined with either immune checkpoint inhibitors (e.g., immunoglobulins against immune programmed cell death (PD) 1/PD ligand 1 or CD8+ T lymphocyte antigen 4) or traditional Chinese medicine drugs. Regarding clinical effectiveness and safety, iRT increases overall and progression-free survival and tumor control rate among patients with NSCLC but without a considerable increase in toxicity risk. We finally discuss iRT challenges and future directions reported over 2018-2023.
RESUMO
Objective To investigate the clinical efficacy of aprepitant in the treatment of cisplatin based chemotherapy in-duced nausea and vomiting.Methods The tumor patients treated with cisplatin(80 mg/m2)chemotherapeutic regimen in Affiliated Shantou Hospital of Sun Yat-Sen University from December 1,2014 to December 1,2016 were selected,61 cases still had vomiting after using granisetron and dexamethasone for routinely stopping vomiting,the patients with aprepitant and dexamethasone for fur-ther stopping vomiting served as the aprepitant group,while the patients with granisetron and dexamethasone as the granisetron group.Then the complete response(CR)rates within 24,24-72,>72-144 h were observed in the two groups.Results The CR rates within 24 h in the aprepitant group and granisetron group were 66.67% and 51.61% respectively,the difference was not sta-tistically significant(P=0.232),which at 24-72 h were 80.00% and 54.84% respectively,the aprepitant group was significantly better than the granisetron group(P=0.036),which at >72-144 h were 86.67% and 64.52% respectively,the aprepitant group was better than the granisetron group(P=0.045).The comparison of adverse reactions between the two antiemetic drugs found that constipation,diarrhea,urticaria,fatigue and anxiety had no significant difference(P>0.05),the occurrence rate of total adverse reactions in the aprepitant group was 23.33%,which in the granisetron group was 25.81%,the difference between the two groups was not statistically significant(P>0.05).Conclusion Aprepitant combined with dexamethasone has better effect for treating hy-peremetic chemotherapy drug cisplatin chemotherapy caused nausea and vomiting with good tolerance.
