Compared to non‐small‐cell lung cancer (NSCLC), SCLC treatment progresses slowly. Although SCLC is highly sensitive to chemotherapy during the initial treatment, most patients still experience resistance and recurrence after receiving chemotherapy. A meta‐analysis demonstrated that thoracic radiotherapy (TRT) improves overall survival in SCLC. The results of the CALGB and CONVERT trials provide evidence for the efficacy of once‐daily high‐dose TRT. TRT at 60 Gy administered twice daily significantly improved survival without increasing toxicity. The long‐standing debate over the optimal timing of radiotherapy has not been fully resolved. SBRT has excellent local control rates and is a safe and effective treatment option for patients with stage I or II SCLC. Prophylactic cranial irradiation (PCI) is used to reduce treatment‐related neurotoxicity to the extent that there has been a recent discussion on whether magnetic resonance imaging (MRI) monitoring can replace PCI. Radiotherapy combined with immunotherapy significantly improves the survival rate of patients with NSCLC; however, its clinical effectiveness has not been systematically explored in patients with SCLC. Therefore, we summarize the evolving therapeutic strategies, (TRT for limited stage‐SCLC and consolidative TRT for extensive stage‐SCLC) and improved radiotherapy techniques (role of SBRT in stage I or II node‐negative SCLC, progress of PCI, and stereotactic radiosurgery), and discuss the possibilities and prospects of radiotherapy combined with immunotherapy for SCLC.","PeriodicalId":32406,"journal":{"name":"Precision Radiation Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47930366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods In this prospective study, 100 patients with cervical cancer who were admitted to Chongqing University Cancer Hospital between July 2021 and April 2022 were randomly divided into an analgesia group (n = 50) and a control group (n = 50). The visual analog scale (VAS) scores at applicator placement‐T1, CT‐scan‐T2, and removal ‐T3, self‐rating anxiety scale (SAS) and self‐rating depression scale (SDS) scores before brachytherapy, short‐term clinical efficacy, and patient satisfaction were compared between the two groups. Results The VAS score of the analgesia group was significantly different at T1 (0 vs. 4.34±1.02, t = 67.40, p < 0.001), but not in the control group; however, there was no significant difference between the two groups at T2 ( t = ‐0.49, p = 0.623) and T3 ( t = ‐0.12, p = 0.912). The SAS and SDS scores first decreased and then increased in the analgesic group and increased in the control group with increasing brachytherapy time. Except for the first measurement, the differences between the two groups were statistically significant (all p < 0.001). The application of interstitial implantation ( p = 0.027), local efficacy ( p = 0.047), and patient satisfaction rates ( p = 0.025) were higher in the analgesic group than in the control group. Conclusion Analgesia can relieve pain, maintain physical and mental health, and improve outcomes and patient satisfaction rates for cervical cancer.","PeriodicalId":32406,"journal":{"name":"Precision Radiation Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135776182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
