Introduction: Hypersensitivity reactions (HSRs), an unpredictable and sometimes harmful reaction, may hamper the effectiveness of chemotherapy and lead to the need for drug switching. The recall of ranitidine from the drug market due to the N-nitrosodimethylamine production necessitates the identification of a proper alternative for the prevention of HSRs. Our study aimed to evaluate the efficacy of oral famotidine in the prevention of HSRs in patients who received chemotherapy agents, particularly platinum-based and taxanes.

Methods: A total of 426 patients who were treated with platinum-based agents or taxanes as part of their regimen were divided into two groups. The famotidine group, including 213 patients, received the standard premedication along with an oral dose of 40 mg famotidine the night before and 1 h prior to the chemotherapy session. The control group, also including 213 patients, received only the standard premedication without famotidine.

Results: Based on the results of this study, six patients in the control group experienced HSRs with a range of varying severities. No HSRs were observed by any of the patients in the famotidine group (p-value = 0.022).

Conclusion: Administration of oral famotidine is beneficial in preventing chemotherapy-induced HSRs.

Clinical trial registration: It was also registered with the Iran Clinical Trial Centre under code IRCT20160310026998N13.

Aim: Smoking is a chronic relapsing condition that is under-reported in oncology settings. People who report current smoking (CS) and those who report recently quitting smoking (RQ) should receive cessation support when they are diagnosed with cancer. The study aimed to identify whether differences exist in the smoking cessation support given to CS and RQ in oncology and what advice is given regarding the benefits of cessation.

Method: A survey exploring smoking cessation practices was completed by oncology clinicians (medical, nursing, and allied health) at nine cancer centers in Australia. Data were analyzed using mixed-effects ordinal regression modeling.

Results: Across the 177 clinicians completing the survey, the reported provision of smoking cessation care was significantly higher for CS than for RQ in relation to asking about smoking status (odds ratio [OR] 3.03, p = 0.001), advice on the benefits of quitting (OR 2.86, p = 0.001), and advice to call the Quitline (OR 5.08, p < 0.001). Exploratory analyses indicated doctors and nurse specialists were four times more likely to report referring CS to a Quitline compared to RQ (OR 4.38, p = 0.001; OR 4.29, 95%, p = 0.005, respectively). The cessation benefits that clinicians most often cited to their patients was that quitting "can reduce the chance of developing treatment complications and side effects".

Conclusion: The relative lack of smoking cessation care provided to RQ in oncology suggests that the high risk of smoking relapse is not well-recognized. Greater awareness and training are needed regarding advising RQ about the survival-specific benefits of continuing to not smoke, offering referrals, and offering follow-up support.

Shortening treatment time with moderately hypofractionated radiotherapy benefits patients by reducing inconvenience and costs, but its use in the definitive treatment of unresectable Stage 3 non-small cell lung cancer is controversial due to lack of level one evidence and toxicity concerns. Pivotal systemic therapy trials utilize conventionally fractionated chemoradiation at 2 Gy per fraction given over 6 weeks. In practice, 4 weeks of chemoradiation at 2.75 Gy per fraction is sometimes employed to reduce the treatment burden for selected patients, especially those who are older or have comorbidities. It is uncertain if the two fractionation regimens are similar in biologically effectiveness, especially with varying systemic therapy. This systematic review aimed to collate the survival and toxicity outcomes for 4 weeks of moderately hypofractionated chemoradiation, using > 50 -60 Gy in 20 fractions. Eight studies met the eligibility criteria; seven studies were from a database search of MEDLINE, EMBASE, Cochrane Library, and Web of Science and one study was added later. Two studies were prospective randomized trials and six were retrospective cohort studies. No study included immunotherapy. The historical evidence has been limited, but emerging data is promising, especially when compared to outcomes of standard chemoradiation. Thus, further investigation of this strategy is justified.

Introduction: Despite the increased demand for medical cannabis (MC), MASCC guidelines state that there is insufficient evidence of its efficacy and safety. Although research has explored medical professionals' perceptions of MC, there is to our knowledge minimal research exploring patients' perceptions, particularly in an Australian cancer setting.

Methods: A survey of Australian cancer patients attending oncology outpatient clinics was performed. Patients were ≥ 18 years and had a confirmed diagnosis of cancer (solid or hematological).

Results: A total of 413 patients were approached between April 2019 and March 2020 out of which 82% (350) consented to participate. A total of 19% (67/350) were using MC. Despite being used for symptom control, such as pain (61%), and, in some cases for perceived anticancer activity (12% to cure, and 16% to slow the cancer), only a minority of users believed that the evidence was of high quality for these indications (28% for physical benefits and 29% for anticancer activity). Nonusers were even more skeptical of the evidence for these indications (17% and 11%, respectively). Only a minority of patients (31% of users and 8% of nonusers) accessed information on MC from clinicians. Most instead relied on resources such as TV, friends, family, social media, and websites.

Conclusion: This study demonstrates current real-world cancer patients' perceptions on the evidence for MC, the sources of information used to shape their health beliefs, and compares users to nonusers. The results highlight the need for treating teams to combat potential misinformation that patients may be accessing about MC and provide information on treatments with stronger evidence.

导言:尽管对医用大麻(MC)的需求有所增加,但MASCC指南指出,没有足够的证据证明其有效性和安全性。虽然有研究探讨了医学专业人员对MC的看法,但据我们所知,探讨患者看法的研究很少,特别是在澳大利亚的癌症环境中。方法:对在肿瘤门诊就诊的澳大利亚癌症患者进行调查。患者年龄≥18岁,确诊为癌症(实体或血液学)。结果:在2019年4月至2020年3月期间,共接触了413名患者,其中82%(350)同意参与。总共有19%(67/350)的患者使用MC。尽管MC用于症状控制,如疼痛(61%),在某些情况下用于感知抗癌活性(12%用于治愈,16%用于减缓癌症),但只有少数用户认为这些适应症的证据质量高(28%用于身体益处,29%用于抗癌活性)。非使用者对这些适应症的证据更加怀疑(分别为17%和11%)。只有少数患者(31%的使用者和8%的非使用者)从临床医生那里获得了关于MC的信息。大多数人转而依赖电视、朋友、家人、社交媒体和网站等资源。结论:本研究展示了当前现实世界癌症患者对MC证据的看法,用于塑造其健康信念的信息来源,并比较了使用者和非使用者。研究结果强调,治疗团队需要打击患者可能获得的关于MC的潜在错误信息,并提供有更有力证据的治疗信息。

Some patients with metastatic castration-resistant prostate cancer (mCRPC) possess germline or acquired defects in the DNA damage repair (DDR) genes BRCA1 and BRCA2. Tumors with BRCA mutations exhibit sensitivity to poly-ADP ribose polymerase inhibitors (PARPi) such as olaparib and rucaparib. As a result, molecular diagnostic testing to identify patients with BRCA mutations eligible for the PARPi therapy has become an integral component of managing patients with mCRPC. There are practical challenges in the current molecular testing pathway in Australia that can compromise testing success. Testing success is often contingent on quality of tissue handling and laboratory processing techniques to minimize DNA degradation and suboptimal sequencing data quality. Greater adoption of best testing practices in Australia can be facilitated with education and greater awareness of expert recommendations. Here, we provide expert recommendations on how to optimize BRCA molecular diagnostic testing in patients with mCRPC. Optimization and standardization of molecular diagnostic testing will support health care providers and institutes in establishing more efficient testing pathways, enabling access to targeted therapies such as PARPi, and improving patient outcomes.

一些转移性去势抵抗性前列腺癌(mCRPC)患者具有DNA损伤修复(DDR)基因BRCA1和BRCA2的种系或获得性缺陷。BRCA突变的肿瘤对多聚adp核糖聚合酶抑制剂(PARPi)如奥拉帕尼和鲁卡帕尼敏感。因此,识别BRCA突变患者是否适合PARPi治疗的分子诊断测试已成为管理mCRPC患者不可或缺的组成部分。在澳大利亚目前的分子检测途径中存在一些实际的挑战,这些挑战可能会影响检测的成功。测试的成功往往取决于组织处理和实验室处理技术的质量,以尽量减少DNA降解和次优测序数据质量。通过教育和提高对专家建议的认识,可以促进澳大利亚更多地采用最佳测试做法。在此,我们就如何优化mCRPC患者的BRCA分子诊断检测提供专家建议。分子诊断测试的优化和标准化将支持卫生保健提供者和研究机构建立更有效的测试途径,使人们能够获得PARPi等靶向治疗,并改善患者的治疗效果。

Aim: Manatū Hauora, the Ministry of Health of New Zealand (NZ), published minimum standards for molecular testing of colorectal cancers (CRCs) in June 2018. These included mismatch repair (MMR) testing at diagnosis and BRAFV600E mutation analysis on newly diagnosed stage IV CRCs. This study aimed to determine the proportion of patients with CRC in the South Island of NZ with metastatic deficient mismatch repair (dMMR) CRC, the proportion of metastatic CRCs and dMMR CRCs that have a BRAFV600E mutation, and audit testing for BRAF mutations and appropriate referral to genetics services.

Methods: People from the South Island with histologically diagnosed colorectal adenocarcinoma between July 1, 2018, and June 30, 2019, were identified by the National Cancer Registry. Data points extracted from the electronic medical record included staging, MMR status, BRAF mutation testing, and genetics referral.

Results: A total of 845 patients met the inclusion criteria; 166 of 845 (19.6%) had dMMR CRC, and of these 130 (78%) had BRAF mutation, 256 patients developed metastatic disease by data cut-off, 20 (7.8%) had dMMR, and 41 (22.2%) had BRAF mutation. When indicated, 275 of 330 (83.3%) were tested for BRAF mutation and 32 of 45 (71.1%) referred to genetics. Compared with other populations, South Island CRC patients had higher rates of dMMR and BRAF mutation.

Conclusion: Less than 10% of patients (n = 20) had metastatic dMMR CRC. These patients could be considered candidates for immune checkpoint inhibitor therapy, a small number that would not significantly burden the NZ health system if funded. The vast majority of dMMR CRC was sporadic. Rates of testing could be improved.

目的:新西兰卫生部(NZ)于2018年6月发布了结直肠癌(crc)分子检测的最低标准。其中包括诊断时的错配修复(MMR)测试和新诊断的IV期crc的BRAFV600E突变分析。本研究旨在确定新西兰南岛转移性缺陷错配修复(dMMR) CRC患者的比例,转移性CRC和dMMR CRC具有BRAFV600E突变的比例,以及BRAF突变的审计测试和适当的转诊到遗传学服务。方法:2018年7月1日至2019年6月30日期间,来自南岛的组织学诊断为结直肠腺癌的患者由国家癌症登记处确定。从电子病历中提取的数据点包括分期、MMR状态、BRAF突变检测和遗传学转诊。结果:845例患者符合纳入标准;845例患者中有166例(19.6%)患有dMMR CRC,其中130例(78%)患有BRAF突变,截至数据截止,256例患者发生转移性疾病,20例(7.8%)患有dMMR, 41例(22.2%)患有BRAF突变。当有指示时,330人中有275人(83.3%)进行了BRAF突变检测,45人中有32人(71.1%)进行了遗传学检测。与其他人群相比,南岛结直肠癌患者dMMR和BRAF突变率较高。结论:不到10%的患者(n = 20)有转移性dMMR CRC。这些患者可以考虑接受免疫检查点抑制剂治疗,如果得到资助,少数患者不会给新西兰卫生系统带来重大负担。绝大多数dMMR CRC是散发性的。检测率可以提高。

Aim: Breast cancer (BC) is the most frequently diagnosed malignancy worldwide, necessitating continued research into its molecular mechanisms. Circular RNAs (circRNAs) are increasingly recognized for their role in various cancers, including BC. This study explores the role of circRNA kinesin family member 4A (circKIF4A) in BC progression and its underlying molecular mechanisms.

Methods: BC cell lines were cultured, and circKIF4A expression was knocked down. Cell viability, proliferation, migration, and invasion were assessed using the Cell Counting Kit-8, colony formation assay, and Transwell assays. The expression of circKIF4A, miR-874-3p, and glycerophosphodiester phosphodiesterase domain-containing 5 (GDPD5) was quantified using qRT-PCR and Western blot analysis. Subcellular fractionation was performed to localize circKIF4A within the cell. The interactions between circKIF4A and miR-874-3p, as well as between miR-874-3p and GDPD5, were evaluated using RNA pull-down and dual-luciferase assays. Rescue experiments were conducted with miR-874-3p inhibition or GDPD5 overexpression to confirm the mechanistic pathway.

Results: circKIF4A was found to be upregulated in BC cells. Its knockdown significantly inhibited cell proliferation, migration, and invasion. circKIF4A acts as a sponge for miR-874-3p, reducing its expression. miR-874-3p targets and suppresses GDPD5, a key regulator in BC cell growth. Silencing miR-874-3p or overexpressing GDPD5 reversed the tumor-suppressive effects of circKIF4A knockdown.

Conclusion: circKIF4A promotes BC cell proliferation and invasiveness by regulating the miR-874-3p/GDPD5 axis. These findings highlight a potential therapeutic target in BC and contribute to the understanding of circRNA involvement in cancer progression.

目的:乳腺癌(BC)是世界范围内最常见的恶性肿瘤,需要继续研究其分子机制。环状rna (circRNAs)在包括BC在内的各种癌症中的作用越来越得到认可。本研究探讨了circRNA激酶家族成员4A (circKIF4A)在BC进展中的作用及其潜在的分子机制。方法:培养BC细胞系,敲低circKIF4A的表达。使用细胞计数试剂盒-8、菌落形成试验和Transwell试验评估细胞活力、增殖、迁移和侵袭。使用qRT-PCR和Western blot分析定量circKIF4A、miR-874-3p和甘油磷酸二酯磷酸二酯酶结构域5 (GDPD5)的表达。进行亚细胞分离以定位细胞内的circKIF4A。circKIF4A与miR-874-3p之间以及miR-874-3p与GDPD5之间的相互作用通过RNA下拉和双荧光素酶测定来评估。通过miR-874-3p抑制或GDPD5过表达的救援实验来确认其机制途径。结果:circKIF4A在BC细胞中表达上调。其敲低可显著抑制细胞增殖、迁移和侵袭。circKIF4A作为miR-874-3p的海绵,降低其表达。miR-874-3p靶向并抑制GDPD5, GDPD5是BC细胞生长的关键调节因子。沉默miR-874-3p或过表达GDPD5可逆转circKIF4A敲低的肿瘤抑制作用。结论:circKIF4A通过调节miR-874-3p/GDPD5轴促进BC细胞增殖和侵袭性。这些发现强调了BC中潜在的治疗靶点,并有助于理解circRNA参与癌症进展。

Purpose: Our study aims to evaluate the characteristics of serum soluble PD-1 (sPD-1) and soluble PD-L1 (sPD-L1) levels and their correlations with immune status and prognosis in advanced lung cancer patients.

Methods: Patients diagnosed with advanced lung cancer based on histology or cytology in Peking University People's Hospital from July 2020 to November 2021 were enrolled. Clinicopathological data were recorded and analyzed. Treatment efficacy was evaluated according to RESIST 1.1 criteria. The serum levels of sPD-L1 and sPD-1 were detected by enzyme-linked immunosorbent assay (ELISA). Lymphocyte subsets were measured by flow cytometry to evaluate the immune status of the patients.

Results: A total of 65 patients with advanced lung cancer were enrolled. sPD-L1 level in lung cancer patients (15.67 ± 11.09 pg/mL, p = 0.001) was significantly higher than those in healthy controls (5.21 ± 4.46 pg/mL). sPD-1 level did not show a significant difference between patients with lung cancer and healthy controls. sPD-L1 level in patients with progressive disease (PD) was significantly higher than those with partial response (PR) (20.94 ± 8.91 vs. 13.14 ± 12.66 pg/mL, p = 0.033). In treatment-naïve patients, sPD-L1 level was negatively correlated with the lymphocyte ratio (correlation coefficient = -0.452, p = 0.014). Kaplan-Meier survival analysis showed that patients with low sPD-L1 level had a significantly longer progression-free survival (PFS) (10.4 vs. 5.7 months, p = 0.023). However, sPD-1 level did not correlate with lymphocyte subsets or prognosis in overall patients with lung cancer. Subgroup analysis showed that prolonged PFS in patients with low sPD-L1 level was exclusively shown in the NSCLC subgroup, not in the SCLC subgroup. In the subgroups of patients who subsequently received immunotherapy, low sPD-L1 level was correlated with longer PFS in the overall patients and NSCLC patients, and low sPD-1 level was correlated with longer PFS exclusively in NSCLC patients.

Conclusion: Serum sPD-L1 level was higher in patients with advanced lung cancer than healthy individuals, which was negatively correlated with the proportion of lymphocytes and prognosis. Serum sPD-1 level did not show significant difference between patients with lung cancer and healthy individuals, which showed no correlation with lymphocyte subsets and the prognosis of overall patients, except NSCLC patients receiving immunotherapy.

目的:探讨晚期肺癌患者血清可溶性PD-1 (sPD-1)和可溶性PD-L1 (sPD-L1)水平的变化特点及其与免疫状态和预后的关系。方法:选取2020年7月至2021年11月北京大学人民医院经组织学或细胞学检查诊断为晚期肺癌的患者。记录并分析临床病理资料。按照RESIST 1.1标准评价治疗效果。采用酶联免疫吸附试验(ELISA)检测血清sPD-L1和sPD-1水平。采用流式细胞术检测淋巴细胞亚群,评价患者的免疫状态。结果:共纳入65例晚期肺癌患者。肺癌患者sPD-L1水平(15.67±11.09 pg/mL, p = 0.001)显著高于健康对照组(5.21±4.46 pg/mL)。肺癌患者与健康对照组之间sPD-1水平无显著差异。进展性疾病(PD)患者的sPD-L1水平显著高于部分缓解(PR)患者(20.94±8.91 vs. 13.14±12.66 pg/mL, p = 0.033)。treatment-naïve患者sPD-L1水平与淋巴细胞比例呈负相关(相关系数= -0.452,p = 0.014)。Kaplan-Meier生存分析显示,低sPD-L1水平患者的无进展生存期(PFS)显著延长(10.4个月vs. 5.7个月,p = 0.023)。然而,sPD-1水平与整体肺癌患者的淋巴细胞亚群或预后无关。亚组分析显示,低sPD-L1水平患者的PFS延长只出现在NSCLC亚组,而不出现在SCLC亚组。在随后接受免疫治疗的患者亚组中,低sPD-L1水平与整体患者和非小细胞肺癌患者的PFS延长相关,低sPD-1水平仅与非小细胞肺癌患者的PFS延长相关。结论:晚期肺癌患者血清sPD-L1水平高于健康人群,且与淋巴细胞比例及预后呈负相关。血清sPD-1水平在肺癌患者与健康个体之间无显著差异,与淋巴细胞亚群及整体患者预后无相关性,但接受免疫治疗的非小细胞肺癌患者除外。

Aim: The response rates to immune checkpoint inhibitors (ICI) remain low (13%-20%) in metastatic head and neck cancer patients, indicating an urgent need to better understand factors predictive of response to these agents. This study explored the impact of smoking status, marijuana use, and alcohol consumption on treatment outcomes in recurrent-metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) patients treated with ICI.

Methods: A retrospective analysis was performed on 201 R/M HNSCC patients treated with ICI between January 15th 2016 and April 9th 2020 at a single institution.

Results: Gender: 154 male (77%), 47 female (23%). Median age 61 (IQR: 55-68). ICI drug: pembrolizumab 100 (50%), nivolumab 91 (45%), nivolumab + ipilimumab 10 (5%). Line of therapy: first: 98 (49%), second and beyond: 103 (51%). Tumor site: oropharynx 84 (42%), oral cavity 45 (22%), larynx 26 (13%), other sites 46 (23%). p16 tumor status: negative 132 (66%), positive 69 (34%). Smoking status: former 111 (55%), never 54 (27%), current 36 (18%), median pack-year 18 (IQR: 0-37). Alcohol use: yes 110 (55%), no 91 (54%). Marijuana use: yes 47 (23%), no 154 (77%). Overall response rate: 36 (18%). Median OS: 12 months (95% CI: 9.4-14.8). Tobacco: former (HR: 0.75, 95% CI: 0.50, 1.11), current (HR: 0.58, 95% CI: 0.33, 1.02). Marijuana: yes (HR: 0.93, 95% CI: 0.58, 1.49). Alcohol: yes (HR: 1.04, 95% CI: 0.72, 1.49).

Conclusion: In our cohort, smoking status, marijuana use, and alcohol consumption did not have a statistically significant impact on OS in patients with R/M HNSCC treated with ICI.

目的:转移性头颈癌患者对免疫检查点抑制剂(ICI)的反应率仍然很低(13%-20%),这表明迫切需要更好地了解对这些药物反应的预测因素。本研究探讨了吸烟状况、大麻使用和饮酒对ICI治疗复发转移(R/M)头颈部鳞状细胞癌(HNSCC)患者治疗结果的影响。方法:回顾性分析2016年1月15日至2020年4月9日在同一医院接受ICI治疗的201例R/M HNSCC患者。结果:性别:男性154例(77%),女性47例(23%)。中位年龄61岁(IQR: 55-68)。ICI药物:pembrolizumab 100 (50%), nivolumab 91 (45%), nivolumab + ipilimumab 10(5%)。一线治疗:98例(49%),二线及以上:103例(51%)。肿瘤部位:口咽部84例(42%),口腔45例(22%),喉部26例(13%),其他46例(23%)。P16肿瘤状态:阴性132例(66%),阳性69例(34%)。吸烟状况:既往111例(55%),从未54例(27%),当前36例(18%),中位包年18 (IQR: 0-37)。饮酒:有110人(55%),没有91人(54%)。吸食大麻:有47人(23%),没有154人(77%)。总体回应率:36(18%)。中位生存期:12个月(95% CI: 9.4-14.8)。烟草:以前(HR: 0.75, 95% CI: 0.50, 1.11),现在(HR: 0.58, 95% CI: 0.33, 1.02)。大麻:是的(HR: 0.93, 95% CI: 0.58, 1.49)。酒精:有(相对危险度:1.04,95%可信区间:0.72,1.49)。结论:在我们的队列中,吸烟状况、大麻使用和饮酒对ICI治疗的R/M HNSCC患者的OS没有统计学意义上的显著影响。

Introduction: The role of afatinib in the first-line treatment of EGFR-mutant advanced non-small cell lung cancer (NSCLC) patients has been proven through clinical trials and real-world studies. However, additional data on the effectiveness of afatinib in patients with brain metastases are lacking.

Methods: EGFR-mutant NSCLC patients with brain metastases were retrospectively reviewed across nine cancer centers in Vietnam from April 1, 2018 to June 1, 2022. The primary endpoints included central nervous system progression-free survival (CNS-PFS) and overall survival (OS). The secondary endpoints were the objective response rate (ORR) and CNS-ORR.

Results: Among 87 enrolled patients, 21.8%, 17.2%, and 60.9% received whole-brain radiation, gamma knife, and no locoregional therapy, respectively. With a median follow-up of 32.2 months for CNS-PFS and 35.3 months for OS, the median CNS-PFS and OS were 17.9 and 29.9 months, respectively. In multivariate analysis, patients receiving whole-brain radiation had significantly shorter CNS-PFS than those untreated with local therapy (16.1 vs. 22.6 months, p = 0.019), but not translating to an inferior OS. Furthermore, both the CNS-PFS and OS of patients with uncommon mutations were significantly worse than those of patients with Del19 (11.3 vs. 24.2 months, p = 0.013 and 17.7 vs. 34.0 months, p = 0.003, respectively). Univariate and multivariate analyses showed that a lower afatinib starting dose did not significantly affect CNS-PFS or OS. The CNS-ORR and ORR were 77.4% and 71.3%, respectively.

Conclusion: In our real-world study, afatinib showed encouraging effectiveness in Vietnamese patients with EGFR-mutant NSCLC and brain metastases at baseline.

简介:阿法替尼在egfr突变晚期非小细胞肺癌(NSCLC)患者一线治疗中的作用已通过临床试验和现实世界研究得到证实。然而,关于阿法替尼在脑转移患者中的有效性的其他数据缺乏。方法:回顾性分析2018年4月1日至2022年6月1日越南9个癌症中心的egfr突变NSCLC脑转移患者。主要终点包括中枢神经系统无进展生存期(CNS-PFS)和总生存期(OS)。次要终点为客观缓解率(ORR)和CNS-ORR。结果:87例入组患者中,21.8%、17.2%和60.9%分别接受了全脑放疗、伽玛刀治疗和无局部治疗。CNS-PFS组和OS组的中位随访时间分别为32.2个月和35.3个月,CNS-PFS和OS组的中位随访时间分别为17.9个月和29.9个月。在多变量分析中,接受全脑放疗的患者的CNS-PFS明显短于未接受局部治疗的患者(16.1个月vs. 22.6个月,p = 0.019),但并未转化为较差的OS。此外,不常见突变患者的CNS-PFS和OS均明显差于Del19患者(分别为11.3 vs. 24.2个月,p = 0.013和17.7 vs. 34.0个月,p = 0.003)。单因素和多因素分析显示,较低的阿法替尼起始剂量对CNS-PFS或OS没有显著影响。CNS-ORR和ORR分别为77.4%和71.3%。结论:在我们真实世界的研究中,阿法替尼在基线egfr突变的越南NSCLC和脑转移患者中显示出令人鼓舞的有效性。

Furthermore, both the CNS-PFS and OS of patients with uncommon mutations were significantly worse than those of patients with Del19 (11.3 vs. 24.2 months, p = 0.013 and 17.7 vs. 34.0 months, p = 0.003, respectively). Univariate and multivariate analyses showed that a lower afatinib starting dose did not significantly affect CNS-PFS or OS. The CNS-ORR and ORR were 77.4% and 71.3%, respectively.</p><p><strong>Conclusion: </strong>In our real-world study, afatinib showed encouraging effectiveness in Vietnamese patients with EGFR-mutant NSCLC and brain metastases at baseline.</p>","PeriodicalId":8633,"journal":{"name":"Asia-Pacific journal of clinical oncology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
