Purpose

This study aims to assess the feasibility and efficacy of high-dose rate (HDR) brachytherapy (BT) administered in a single insertion with 4 treatment sessions for locally advanced cervical cancer and to identify the prognostic factors influencing outcomes.

Methods and Materials

We retrospectively analyzed the clinical data of patients with cervical cancer with locally advanced disease (International Federation of Gynecology and Obstetrics 2018 IB-IVB) treated at our institution from January 2014 through December 2021. Each patient received definitive radiation therapy with an external irradiation dosage between 45 and 50.4 Gy along with concurrent chemotherapy. HDR-BT (24 Gy) was prescribed to a high-risk clinical target volume.

Results

One hundred thirty-nine patients were included and the HDR-BT program could be fully performed in 136 patients (98%). Over a median follow-up duration of 40.5 months, the 2-year local control (LC), overall survival (OS), and disease-free survival rates stood at 79.4%, 77.7%, and 61.7%, respectively, with 5-year rates at 78.2%, 61.6%, and 55.7%. Multivariate analysis revealed the primary determinant of LC as the tumor's response to external beam radiation therapy as determined via magnetic resonance imaging before BT. Parametrial involvement demonstrated a significant multivariate association with disease-free survival (P = .04). Regarding OS, parametrial invasion (P = .01) and the tumor's response postchemoradiotherapy (P = .02) emerged as significant factors. Regarding chronic toxicities, 18% (25 patients) experienced grade 3 complications. An optimal D2 cc (bowel) threshold of 70 Gy (P = .001) was identified to limit chronic digestive complications of grade 3 or higher.

Conclusions

The implementation of single-insertion, 4-session HDR-BT could be performed in 98% of the patients. It yields favorable LC and OS rates, coupled with tolerable toxicity in patients with locally advanced cervical cancer. Response to initial chemoradiotherapy evaluated on pre-BT magnetic resonance imaging is an important prognostic factor and could help to individualize therapeutic strategies.

目的本研究旨在评估高剂量率(HDR)近距离放射治疗(BT)单次插入治疗局部晚期宫颈癌的可行性和疗效,并确定影响疗效的预后因素。方法和材料我们回顾性分析了2014年1月至2021年12月在我院接受治疗的局部晚期宫颈癌患者(国际妇产科联盟2018年IB-IVB)的临床数据。每位患者都接受了明确的放疗,外照射剂量介于 45 至 50.4 Gy 之间,并同时接受化疗。结果 139 名患者被纳入其中,136 名患者(98%)完全接受了 HDR-BT(24 Gy)治疗。中位随访时间为 40.5 个月,2 年局部控制率(LC)、总生存率(OS)和无病生存率分别为 79.4%、77.7% 和 61.7%,5 年生存率分别为 78.2%、61.6% 和 55.7%。多变量分析显示,LC的主要决定因素是BT前通过磁共振成像确定的肿瘤对外照射治疗的反应。宫旁受累与无病生存率有显著的多变量相关性(P = .04)。在OS方面,宫旁侵犯(P = .01)和肿瘤放化疗后的反应(P = .02)成为重要因素。在慢性毒性方面,18%(25 名患者)出现了 3 级并发症。最佳D2 cc(肠道)阈值为70 Gy (P = .001),以限制3级或更高级别的慢性消化道并发症。在局部晚期宫颈癌患者中,该疗法可获得良好的LC和OS率,且毒性可耐受。BT前磁共振成像评估的初始化放疗反应是一个重要的预后因素,有助于制定个体化治疗策略。

Purpose

Initial studies investigating the combination of local and systemic treatments in advanced esophageal cancer (EC) have conflicting conclusions regarding survival benefits. The objective of this systematic review and meta-analysis is to assess the efficacy of the addition of local therapy to systemic treatments in patients with advanced EC.

Methods and Materials

A systematic literature search was conducted in the PubMed, EMBASE, and CENTRAL databases. Key eligibility criteria included studies that enrolled patients with histologically confirmed EC or esophagogastric junction cancer with metastasis or recurrence and compared survival benefits between the combined local and systemic treatment group and the systemic treatment alone group. Survival outcomes, represented by hazard ratios (HRs) of progression-free survival (PFS) and overall survival (OS), were pooled using a random effects model. The MINORS score was adopted for quality assessment. Risk of bias was statistically examined by Begg's and Egger's tests.

Results

A total of 1 randomized controlled trial (RCT) and 10 qualified retrospective studies including 14,489 patients were identified. Addition of local therapy to systemic treatment significantly improved PFS (HR, 0.52; 95% CI, 0.37-0.73; P < .001) and OS (HR, 0.69; 95% CI, 0.58-0.81; P < .0001) compared with systemic treatment alone. The subgroup analysis revealed that combined local and systemic treatment conferred a significant survival advantage in both patients with oligometastasis (PFS: HR, 0.45; 95% CI, 0.31-0.64; P < .0001; OS: HR, 0.62; 95% CI, 0.48-0.79; P < .0001) and recurrence (OS: HR, 0.55; 95% CI, 0.37-0.81; P = .002).

Conclusions

In conclusion, addition of local treatment to systemic therapy can improve survival in patients with advanced EC, particularly in those with oligometastasis or recurrent diseases.

目的对晚期食管癌(EC)进行局部治疗与全身治疗相结合的初步研究在生存获益方面得出了相互矛盾的结论。本系统综述和荟萃分析旨在评估晚期食管癌患者在全身治疗的基础上增加局部治疗的疗效。方法和材料在 PubMed、EMBASE 和 CENTRAL 数据库中进行了系统文献检索。主要资格标准包括纳入组织学确诊的食管癌或食管胃交界处癌转移或复发患者的研究,并比较局部和全身联合治疗组与单纯全身治疗组的生存获益。采用随机效应模型对无进展生存期(PFS)和总生存期(OS)的危险比(HRs)表示的生存结果进行了汇总。采用 MINORS 评分进行质量评估。结果 共发现了 1 项随机对照试验(RCT)和 10 项合格的回顾性研究,包括 14,489 名患者。与单纯全身治疗相比,在全身治疗的基础上加用局部治疗可明显改善 PFS(HR,0.52;95% CI,0.37-0.73;P <;.001)和 OS(HR,0.69;95% CI,0.58-0.81;P <;.0001)。亚组分析显示,局部和全身联合治疗为寡转移患者带来了显著的生存优势(PFS:HR,0.45;95% CI,0.31-0.64;P <;.0001;OS:HR,0.62;95% CI,0.48-0.79;P <.0001)和复发(OS:HR,0.55;95% CI,0.37-0.81;P = .002)。结论总之,在全身治疗的基础上增加局部治疗可提高晚期EC患者的生存率,尤其是寡转移或复发患者。

Background

Current standard of care treatment for patients with ≥15 brain metastases (BM) is whole brain radiation therapy (WBRT), despite poor neurocognitive outcomes. We analyzed our institutional experience of treating these patients with stereotactic radiosurgery (SRS), with the aim of evaluating safety, cognitive outcomes, and survival metrics.

Methods

Patients who received SRS for ≥15 BMs in 1 to 5 fractions from 2014 to 2022 were included. Cognitive outcomes were objectively evaluated using serial Patient-Reported Outcome Measurement Information System (PROMIS) scores. The Kaplan-Meier method was used for survival analysis and log-rank test for intergroup comparisons.

Results

Overall, 118 patients underwent 124 courses of LINAC-based SRS. The median number of lesions treated per course was 20 (range, 15-94). Most patients received fractionated SRS to a dose of 24 Gy in 3 fractions (81.5%). At the time of SRS, 19.4% patients had received prior WBRT, and 24.2% had received prior SRS. The rate of any grade radiation necrosis (RN) and grade ≥3 RN were 15.3% and 3.2%, respectively. When evaluating longitudinal PROMIS score trends, 25 of 31 patients had a stable/improved PROMIS score. Patients who did not receive prior brain RT had a longer median survival (7.4 months vs 4.6 months, P = .034). The 12m local control was 97.6%, and the cumulative incidence of distant intracranial failure, with death as a competing event, was 46% (95% CI, 36%, 55%). One year freedom from neurologic death, leptomeningeal disease, and salvage WBRT were 89%, 94.6%, and 84%, respectively.

Conclusion

We present here one of the largest studies evaluating SRS for patients with ≥15 BMs. SRS was safe, had favorable cognitive outcomes, and had comparable survival outcomes to contemporary studies evaluating WBRT in this population. Treatment-naïve patients had a median survival of >6 months, long enough to benefit from cognitive sparing with SRS. Our study supports randomized studies comparing SRS and hippocampal avoidance WBRT approaches for these patients.

背景脑转移灶(BM)≥15 个的患者目前的标准治疗方法是全脑放射治疗(WBRT),尽管其神经认知结果不佳。我们分析了本机构使用立体定向放射外科(SRS)治疗这些患者的经验,旨在评估安全性、认知结果和生存指标。认知结果采用患者报告结果测量信息系统(PROMIS)序列评分进行客观评估。采用Kaplan-Meier法进行生存分析,用log-rank检验进行组间比较。结果共有118名患者接受了124个疗程的基于LINAC的SRS治疗。每个疗程治疗病灶的中位数为20个(范围为15-94)。大多数患者接受了分次 SRS,剂量为 24 Gy,分 3 次进行(81.5%)。在接受 SRS 治疗时,19.4% 的患者曾接受过 WBRT 治疗,24.2% 的患者曾接受过 SRS 治疗。任何等级的放射性坏死(RN)和≥3级RN的发生率分别为15.3%和3.2%。在评估PROMIS评分的纵向趋势时,31名患者中有25人的PROMIS评分稳定/提高。既往未接受脑部RT治疗的患者中位生存期更长(7.4个月 vs 4.6个月,P = .034)。12个月的局部控制率为97.6%,远处颅内衰竭的累积发生率为46%(95% CI,36%,55%),死亡为竞争事件。神经系统死亡、脑外疾病和挽救性WBRT的一年免患率分别为89%、94.6%和84%。SRS是安全的,具有良好的认知结果,其生存结果与当代评估该人群WBRT的研究结果相当。未经治疗的患者的中位生存期为6个月,足够长的时间让他们从SRS的认知功能保护中获益。我们的研究支持对这些患者进行比较 SRS 和海马回避 WBRT 方法的随机研究。

Purpose

The attack by Hamas on Israeli civilians (October 7, 2023) triggered the ongoing war, which could be detrimental to cancer care in general and radiation therapy (RT) in particular. To assure continuity of care within the Radiation Oncology Department of Samson Assuta Ashdod University Hospital (SAAUH), which borders on Gaza, patient-centric measures were redoubled by our institution. This study describes the impact of these measures on patients' perception and their willingness to continue RT, despite fear of war.

Methods and Materials

A survey questionnaire was designed to detect changes in attitude and treatment adherence during war. It was offered to the patients undergoing RT at SAAUH. A Pearson correlation between the items relating to desire to continue the therapy was calculated. Smallest space analysis was conducted to illustrate the association between the variables.

Results

Forty-seven patients enrolled in this study reported a significantly lower feeling of personal safety during wartime in comparison with the confidence in the professionalism of the staff (paired samples t test, t(43) = 4.61; P < .001). Simultaneously, patients perceived that the impact of the national situation on their health was very low (mean of 1.59 on a scale of 1-6). Both the Pearson correlation test and smallest space analysis revealed that the desire to continue treatment in general and to continue treatment at the same department were significantly related to trust in the staff's professionalism.

Conclusions

Fear of war can pose a major pitfall in providing daily RT care. This obstacle may be potentially overridden by creating deep, trusting relationships between the patients and the medical staff.

目的 哈马斯对以色列平民的袭击(2023 年 10 月 7 日)引发了持续不断的战争,这可能会对癌症治疗,特别是放射治疗(RT)造成损害。为了确保与加沙接壤的萨姆森-阿苏塔-阿什杜德大学医院(SAAUH)放射肿瘤科内医疗服务的连续性,我院加倍采取了以患者为中心的措施。本研究描述了这些措施对患者观念的影响,以及他们在恐惧战争的情况下继续接受 RT 治疗的意愿。方法与材料设计了一份调查问卷,以检测战争期间患者态度和治疗依从性的变化。问卷调查对象为在 SAAUH 接受 RT 治疗的患者。计算了与继续治疗愿望有关的项目之间的皮尔逊相关性。结果47名参与研究的患者表示,与对医务人员专业性的信心相比,他们在战时的人身安全感明显降低(配对样本t检验,t(43)= 4.61;P <;.001)。同时,患者认为国家局势对其健康的影响非常小(1-6 级平均值为 1.59)。皮尔逊相关性检验和最小空间分析表明,一般情况下继续治疗的愿望和在同一科室继续治疗的愿望与对工作人员专业精神的信任有显著关系。通过在患者和医务人员之间建立深厚的信任关系,有可能克服这一障碍。

Purpose

Intravascular tumor emboli in axillary soft tissue (ITE) is a rare pathologic finding in breast cancer and is associated with higher axillary nodal disease burden. The independent prognostic and predictive value of this entity is unknown, as is the role of radiation therapy for ITE.

Methods and Materials

We analyzed a prospectively maintained database of breast cancer patients treated from 1992 to 2020. Patients with ITE were matched to those without (1:2) based on propensity scores to control for potential confounding factors. Locoregional (LRR) and distant recurrence (DR) were evaluated using competing risks methods accounting for death as a competing event. Overall survival (OS) and disease-free survival (DFS) were evaluated by Cox regression models. Among patients with ITE, we also evaluated whether RT improved outcomes.

Results

Among 2377 total patients, 129 had ITE, of whom 126 were propensity score matched to 252 without ITE. Median follow-up from time of surgery was 5.5 years (IQR 2.3, 9.7). There were no statistically significant differences in the 5-year incidence of LRR between groups (5.4% [95% CI, 1.6%-13%] with ITE vs 10% [95% CI, 6.7%-15%] without, P = .53) or DR (24% [95% CI, 15% 35%] with ITE vs 21% [95% CI, 16%-27%] without, P = .51). Five-year OS and DFS did not differ between groups (P > .9 for both comparisons, patients with ITE vs without ITE). In analyzing the effect of RT among patients with ITE, receipt of RT was associated with significantly improved DFS (HR, 0.34, 95% CI, 0.12-0.93, P = .04).

Conclusions

Patients with ITE do not exhibit significantly worse LRR, DR, DFS, or OS compared with a propensity-score-matched cohort without ITE. However, among patients with ITE, those who received RT demonstrated significantly improved DFS. Larger studies with longer follow-up are needed to evaluate the prognostic and predictive implications of ITE.

目的腋窝软组织内的血管肿瘤栓子(ITE)是乳腺癌中一种罕见的病理发现,与较高的腋窝结节疾病负担有关。这一实体的独立预后和预测价值以及放疗对 ITE 的作用尚不清楚。方法和材料我们分析了一个前瞻性维护的数据库,该数据库收录了 1992 年至 2020 年接受治疗的乳腺癌患者。根据倾向评分将患有 ITE 的患者与未患有 ITE 的患者进行配对(1:2),以控制潜在的混杂因素。采用竞争风险方法对局部复发(LRR)和远处复发(DR)进行评估,将死亡作为竞争事件。总生存期(OS)和无病生存期(DFS)通过 Cox 回归模型进行评估。在患有 ITE 的患者中,我们还评估了 RT 是否能改善预后。结果在 2377 例患者中,129 例患有 ITE,其中 126 例与 252 例无 ITE 的患者进行了倾向评分匹配。从手术时间算起,中位随访时间为 5.5 年(IQR 2.3,9.7)。各组间的 5 年 LRR 发生率(有 ITE 的为 5.4% [95% CI, 1.6%-13%] vs 无 ITE 的为 10% [95% CI, 6.7%-15%], P = .53)或 DR 发生率(有 ITE 的为 24% [95% CI, 15% 35%] vs 无 ITE 的为 21% [95% CI, 16%-27%], P = .51)差异无统计学意义。各组间的五年期OS和DFS无差异(两组间比较,有ITE与无ITE患者的P均为0.9)。在分析 RT 对 ITE 患者的影响时,接受 RT 与 DFS 的显著改善相关(HR,0.34,95% CI,0.12-0.93,P = .04)。然而,在ITE患者中,接受RT治疗的患者的DFS明显改善。要评估ITE对预后和预测的影响,还需要进行更大规模、更长时间的随访研究。

Purpose

The purpose of this investigation was to evaluate the efficacy and safety of stereotactic body radiation therapy (SBRT) for pulmonary metastases from pediatric sarcomas.

Methods and Materials

This study was a single institutional retrospective chart review including patients younger than 21 years of age at diagnosis who had received SBRT for pulmonary metastasis from metastatic sarcoma. Our current electronic record system was queried for all eligible patients. Primary endpoint was tumor response as defined by Respone Evaluation Criteria in Solid Tumors 1.1 criteria. Secondarily, we analyzed factors that affected tumor response as well as toxicity of treatment. Median dose was 50 Gy ranging from 30 to 60 Gy in 5 fractions to the planning tumor volume.

Results

There were 7 patients, ranging in age from 6 to 21 years with a total of 14 pulmonary lesions treated with SBRT. Median and mean follow-up times for the 7 patients were 10.6 months and 15.9 months, respectively. The complete response rate was 50%, partial response 21%, stable disease 21%, and progressive disease 7%. Four of the 7 patients were treated with concurrent systemic therapy, 3 of which were targeted oral therapies. Additionally, we observed that patients who were on targeted therapy such as regorafenib or pazopanib seemed to have better local control compared with patients without targeted therapy.

Conclusions

With an overall response rate of 92%, SBRT provided a noninvasive effective palliative treatment option with few side effects in this small retrospective study of 7 patients. A larger prospective clinical trial is warranted to evaluate the role of SBRT in the treatment of unresectable metastatic pediatric sarcomas.

本研究旨在评估立体定向体放射治疗(SBRT)治疗小儿肉瘤肺转移的有效性和安全性。方法和材料本研究是一项单一机构的回顾性病历审查,包括诊断时年龄小于 21 岁、因转移性肉瘤肺转移而接受 SBRT 治疗的患者。我们对所有符合条件的患者的现有电子病历系统进行了查询。主要终点是实体瘤反应评估标准 1.1 所定义的肿瘤反应。其次,我们分析了影响肿瘤反应和治疗毒性的因素。中位剂量为 50 Gy,在计划肿瘤体积内分 5 次使用,剂量范围为 30 至 60 Gy。7名患者的中位随访时间和平均随访时间分别为10.6个月和15.9个月。完全反应率为50%,部分反应率为21%,病情稳定率为21%,病情进展率为7%。7 名患者中有 4 人同时接受了全身治疗,其中 3 人接受了口服靶向治疗。此外,我们还观察到,与未接受靶向治疗的患者相比,接受瑞戈非尼或帕唑帕尼等靶向治疗的患者似乎有更好的局部控制效果。结论在这项对7名患者进行的小型回顾性研究中,SBRT的总体反应率为92%,提供了一种副作用小的非侵入性有效姑息治疗方案。有必要进行更大规模的前瞻性临床试验,以评估SBRT在治疗无法切除的转移性小儿肉瘤中的作用。
