Purpose
To evaluate the impact of postmastectomy radiotherapy (PMRT) on immediate breast reconstruction (IBR) outcomes among patients treated with proton or photon radiotherapy.
Material and Methods
Patients who had undergone mastectomy, immediate breast reconstruction, and PMRT at our institution were included in a retrospective analysis of risk factors for surgical site infection (SSI), unplanned reoperation, and reconstruction failure. Univariate Cox models were used to examine associations of variables with reconstruction outcomes.
Results
Two-hundred thirty-one women were included, of whom 224 (97.0 %) underwent two-stage IBR with placement of a tissue expander and 7 (3 %) had direct-to-implant IBR. One-hundred sixty-five patients (71.4 %) received proton and 65 (28.6 %) received photon therapy. Twenty-nine patients (12.6 %) received hypofractionation. Median follow-up was 1.8 years. Two-year cumulative risk of SSI was 17.83 % (95 % CI 12.27–24.41 %); unplanned reoperation was 16.19 % (95 % CI 10.06–22.10 %); and reconstruction failure was 7.60 % (95 % CI 3.55–12.11). On multivariable analysis, prophylactic use of Mepitel Film reduced the risk of SSI [HR: 0.35 (95 % CI: 0.18–0.69), p = 0.002] and unplanned reoperation [HR: 0.39 (95 % CI: 0.20–0.79), p = 0.008]. The small number of events (n = 16) precluded multivariable analysis of reconstruction failure; on univariate analysis, receipt of a chest wall boost [HR: 4.98 (95 % CI: 1.12–22.10), p = 0.035] and/or lymph node boost [HR: 3.66 (95 % CI: 1.25–10.73), p = 0.018] were associated with reconstruction failure.
Conclusions
Although approximately one-fifth of women experienced SSI or unplanned reoperation, the rate of reconstruction failure was low (7.6%) and most women achieved a successful reconstruction outcome with PMRT using photons or protons. The lower rate of SSI and unplanned reoperation with use of Mepitel Film highlights the need for further evaluation.
目的探讨乳房切除术后放射治疗(PMRT)对质子或光子放射治疗患者即刻乳房重建(IBR)结果的影响。材料和方法回顾性分析我院行乳房切除术、即刻乳房重建和PMRT的患者手术部位感染(SSI)、计划外再手术和重建失败的危险因素。单变量Cox模型用于检验变量与重建结果的关联。结果纳入231名妇女,其中224名(97.0%)接受了两期IBR并放置组织扩张器,7名(3%)接受了直接植入IBR。165例(71.4%)接受质子治疗,65例(28.6%)接受光子治疗。29例(12.6%)患者接受了低分割术。中位随访时间为1.8年。两年累积SSI风险为17.83% (95% CI 12.27 - 24.41%);计划外再手术占16.19% (95% CI 10.06 ~ 22.10%);重建失败率为7.60% (95% CI 3.55 ~ 12.11)。在多变量分析中,预防性使用Mepitel Film降低了SSI的风险[HR: 0.35 (95% CI: 0.18-0.69), p = 0.002]和计划外再手术的风险[HR: 0.39 (95% CI: 0.20-0.79), p = 0.008]。事件数量少(n = 16)排除了重建失败的多变量分析;在单因素分析中,胸壁增强[风险比:4.98 (95% CI: 1.12-22.10), p = 0.035]和/或淋巴结增强[风险比:3.66 (95% CI: 1.25-10.73), p = 0.018]与重建失败相关。结论:尽管约五分之一的女性经历过SSI或计划外的再手术,但重建失败率很低(7.6%),大多数女性使用光子或质子进行PMRT成功重建。较低的SSI发生率和使用Mepitel膜的意外再手术突出了进一步评估的必要性。

In locally advanced rectal cancer (LARC), increasing the complete response (CR) rate after total neo-adjuvant treatment may increase the patient eligibility for non-operative management (“watch and wait”, W&W). Although a radiotherapy (RT) boost to the primary tumour may enhance CR rates, clear guidelines are currently lacking. This systematic review and meta-analysis investigate the technical parameters used for rectal boost RT and assess their impact on oncological outcomes.
Methods
Following PRISMA guidelines, the terms “rectum,” “radiotherapy,” and “boost” were searched in PubMed and EMBASE (PROSPERO: CRD42023444685). Studies reporting on external beam RT boost to the primary tumour in LARC and meeting quality criteria were included. Descriptive analyses extracted data on RT technique, preparation, boost delineation, dose, chemotherapy, and follow-up. A mixed-effects meta-analysis model evaluated the impact of selected parameters on CR and local recurrence rate (LRR). Studies were analysed separately based on treatment intent: planned surgery or W&W.
Results
Out of 3904 references, 83 were included in the descriptive analysis and 78 in the meta-analysis. Substantial variability in RT parameters was observed across studies. Pathologic CR rates were significantly higher with intensity-modulated/volumetric-modulated arc RT (IMRT/VMAT, p = 0.007), simultaneous boost (p = 0.020), dose escalation (Biological equivalent dose > 74 Gy, p = 0.035), and the combination of induction and consolidation chemotherapy (p = 0.023). No significant associations were found for clinical CR or LRR.
Conclusion
While rectal RT boost is already part of real-world practices, the wide heterogeneity in techniques highlights the urgent need for standardisation. Our meta-analysis suggests that IMRT/VMAT, simultaneous boost, and dose escalation are associated with higher pathological CR rates and should be considered in future rectal boost guidelines. These findings, however, warrant careful interpretation due to the absence of adjustments for clinical, tumoral, or patient-related parameters that may also influence response rate and oncological outcomes.
在局部晚期直肠癌(LARC)中,提高完全新辅助治疗后的完全缓解率(CR)可能会增加患者接受非手术治疗的资格(“观察和等待”,W&;W)。虽然对原发肿瘤进行放疗(RT)可能会提高CR率,但目前缺乏明确的指导方针。本系统综述和荟萃分析调查了用于直肠增强RT的技术参数,并评估了它们对肿瘤预后的影响。方法按照PRISMA指南,在PubMed和EMBASE (PROSPERO: CRD42023444685)中检索“直肠”、“放疗”和“boost”这三个术语。研究报告了LARC中对原发肿瘤的外束放疗增强并符合质量标准。描述性分析提取了放疗技术、制剂、增强描绘、剂量、化疗和随访方面的数据。混合效应荟萃分析模型评估了所选参数对CR和局部复发率(LRR)的影响。研究根据治疗意图分别进行分析:计划手术或W&;W。结果3904篇文献中,描述性分析纳入83篇,meta分析纳入78篇。在不同的研究中观察到RT参数有很大的可变性。调强/调容弧线放疗(IMRT/VMAT, p = 0.007)、同步增强(p = 0.020)、剂量递增(生物等效剂量>;74 Gy, p = 0.035),诱导合并巩固化疗(p = 0.023)。临床CR或LRR未发现显著相关性。结论虽然直肠RT增强术已经成为现实世界的一部分,但技术的广泛异质性突出了对标准化的迫切需要。我们的荟萃分析表明,IMRT/VMAT、同时增强和剂量递增与更高的病理CR率相关,应在未来的直肠增强指南中予以考虑。然而,由于缺乏对临床、肿瘤或患者相关参数的调整,这些发现需要仔细解释,这些参数也可能影响反应率和肿瘤预后。

Background
Junctional adhesion molecule–like protein (JAML) is highly expressed in cancer tissues of patients with colorectal cancer (CRC) and promotes cancer proliferation. However, the relationship between JAML expression and radiosensitivity of CRC remains unclear.
Methods
Stable CRC cell lines with knocked down or overexpressed JAML were used to evaluate the effects of irradiation on cell viability and cell proliferation using Cell Counting Kit-8 (CCK8) and cell clone formation assay, respectively. Cellular immunofluorescence, flow cytometry, and western blotting were used to determine the mechanism. Tumor-bearing nude mouse models were established to verify the relationships between the expression of JAML and the radiosensitivity of CRC.
Results
The results of CCK8 and cell clone formation assay showed that the viability and proliferation of CRC cells with JAML overexpression were significantly inhibited after exposure to irradiation compared with those of CRC cells with low expression of JAML. DNA damage and cell apoptosis were significantly increased in the JAML-overexpression group compared with the JAML-low-expression group after exposure to irradiation. The phosphorylation of the ataxia telangiectasia and Rad3-related protein (ATR)-checkpoint kinase 1 (CHK1)-mediated DNA damage repair pathway was inhibited in the JAML-overexpression group compared with the JAML-low-expression CRC cells after irradiation. Similar results were observed in CRC xenografts in vivo.
Conclusions
CRC cells with JAML overexpression are more sensitive to radiotherapy of X-rays because of the decreased phosphorylation of the ATR-CHK1-mediated DNA damage repair pathway. The expression of JAML in CRC cells could be used as a predictive biomarker of radiosensitivity in patients with CRC.

Purpose/objective
Quad shot radiotherapy (QS-RT) is integral to head and neck cancer palliative care, but multiple CT-simulations for QS-RT cycles can be burdensome for patients. We evaluated the ability of an online adaptive radiotherapy (ART) workflow (PEAQ-RT) to eliminate extra CT simulations in QS-RT and reduce treatment related burdens.
Materials/methods
Ten patients with head and neck malignancies were enrolled in this prospective study receiving QS-RT for up to three cycles, each comprising four fractions of 350 cGy delivered twice daily, with a total dose of 1400 cGy per cycle. QS-RT could be delivered up to three cycles, spaced three to four weeks apart. Patients underwent standard CT simulation, and the simulation plan served as the treatment plan for the first QS-RT cycle. For subsequent QS-RT cycles, patients proceeded directly to adaptive treatment via institutional online ART protocol. Feasibility was defined as completing this expedited adaptive QS-RT workflow in at least 80 % of attempted adapted fractions.
Results
Ten patients aged 56–89 were enrolled. Eight patients received a second cycle of QS-RT and four patients received a third cycle. PEAQ-RT workflow was feasible in 87.5% (7/8) of patients who received at least one adapted cycle and was feasible in 86% (12/14) of attempted adapted fractions. For the second and third cycles, average total workflow time for the adaptive treatments was 28 min (14–38). All constraint violations were resolved with the use of online adaptation. The PEAQ-RT workflow eliminated a median of 2 (range: 0–2) simulation visits with additional QS-RT cycles. This resulted in a median travel distance savings of 50.8 miles (range: 40.6–848 miles) and a median reduction of 3.5 h in travel time per patient.
Conclusion
PEAQ-RT enabled QS-RT while eliminating the need for additional CT simulation appointments for subsequent cycles.

Purpose
Splenic irradiation can result in life-threatening infections. Updated dose constraints have been recommended for patients undergoing chemoradiotherapy and conventional radiotherapy but splenic constraints were not specified in trials of stereotactic ablative radiotherapy (SABR). We studied splenic doses in patients undergoing SABR for adrenal metastases and late changes in splenic volume (SV).
Material and Methods
Patients treated with breath-hold MR-guided SABR for adrenal metastases were identified from an Ethics-approved database. Splenic dose constraints were not routinely used. The spleen was delineated retrospectively on both breath-hold CT and MR-scans. Mean spleen dose (MSD) and relative V5-10-20-30Gy values were derived from the baseline plan. SV was measured on available follow-up CT scans at 6–12–24 months. Regression analyses were performed to assess SV changes in relation to splenic dose and other parameters.
Results
SABR was delivered to 113 adrenal tumors mostly using 5 fractions (64 % of tumors), 3 fractions (19 %) or a single fraction (14 %). Systemic therapy was administered during or within 3 months preceding/after SABR in 51 % of patients. Left-sided tumors comprised 56 % of total, and baseline median MSD and V10Gy were 9.7 Gy (range 1.5–28.4 Gy) and 46.3 % (range 0–100 %), respectively. Corresponding values for right-sided adrenal plans were 1.5 Gy (0.2–5.9 Gy) and 0 % (0–6.2 %), respectively. In multivariable analysis, a higher MSD was significantly associated with left laterality (p < 0.001), higher prescription dose (p = 0.02), and larger GTV (p < 0.001). An MSD of > 10 Gy was observed in 28 patients (25 %). Among these, a greater than 20 % decrease in SV was found in 46 % of patients with available follow-up at 6 months (n = 59), 40 % at 12 months (n = 47) and 50 % at 24 months (n = 31).
Conclusion
Substantial reductions in spleen volume occur in 40–50 % of patients treated with adrenal SABR with an MSD of >10 Gy. The clinical relevance of splenic atrophy merits further study.

Introduction
The incidence of synchronous metastatic hormone-sensitive prostate cancer (mHSPC) is rising with the increasing use of next-generation imaging. Local radiotherapy (RT) was shown to improve survival in patients with mHSPC; however, new data require a re-assessment of the indication and value of local RT in mHSPC.
Methods
In this prospectively registered systematic review and meta-analysis (CRD42025648251), we searched MEDLINE, Scopus, CENTRAL, and Google Scholar in March 2025 for phase 3 RCTs evaluating the addition of RT to systemic therapy to improve OS in mHSPC patients. Hazard ratios (HRs) were pooled using random-effects meta-analysis. Risk of Bias was assessed with Cochrane’s RoB 2 tool.
Results
Out of the 10,615 individual records, we identified three RCTs: HORRAD (n = 432), STAMPEDE (n = 2,061), and PEACE-1 (n = 1,173). The systemic treatment included androgen deprivation therapy (ADT) in HORRAD, ADT ± Docetaxel in STAMPEDE, and ADT ± Docetaxel ± Abiraterone in PEACE-1 trial. Local RT was not associated with significantly improved OS in all patients (HR = 0.92; 95 % confidence interval [CI] 0.85–1.00; p = 0.06), or in those with low metastatic burden (HR = 0.74; 95 %CI 0.51–1.06; p = 0.1); however, exploratory analyses showed a significant improvement in androgen deprivation resistance-free survival (HR = 0.76; 95 %CI 0.70–0.82; p < 0.001). Local RT was associated with significant reduction in local prostate cancer related events in the HORRAD (18 % vs. 30 %) and PEACE-1 (12 % vs. 22 %) trials, but not in the STAMPEDE trial (49 % vs. 51 %).
Conclusion
Local RT does not improve OS in unselected patients treated with modern systemic therapies for mHSPC. However, it delays ADT resistance and reduces local adverse events, with relatively tolerable toxicity. Future studies should refine selection criteria, ideally using PSMA-PET imaging, dynamic response markers, and/or genomic profiling, to identify mHSPC patients most likely to benefit from local RT.

Background
Symptomatic posttreatment edema (SPTE) is a complication that may develop after radiotherapy for intracranial meningiomas. Our study aims at reviewing rates of SPTE in a large cohort of a single institution and identifying possible predictive factors.
Methods
We retrospectively analyzed data of 293 patients with 304 intracranial meningiomas irradiated at our institution between 2005 and 2018. We evaluated rates of SPTE and investigated numerous factors by univariate and multivariate analysis. Kaplan Meier analysis was used for estimation of actuarial local control and overall survival.
Results
Median age was 60 years. Meningiomas were treated with fractionated stereotactic radiation therapy (70 %), single fraction stereotactic radiosurgery (24 %) or fractionated stereotactic radiosurgery (6 %). Median imaging follow-up was 60 months, actuarial 10 year local control rate for patients with grade 1 meningiomas who received radiotherapy as definitive treatment was 99 %. Local control at 5 years was 94 % for grade 1 meningioma, 57 % and 53 % for grade 2 and 3 respectively. Sixteen patients (5.5 %) developed SPTE, median time to onset was 3 months (range 1–26 months). the higher rates of SPTE observed were in midline (13 %) and convexity (9 %), compared to skull base tumors (2 %). On univariate analysis, age > 60 years (p > 0.03), pretreatment peritumoral edema (p = 0.014), medline location (p = 0.018), tumor size > 30 mm (p = 0.015) and grade 2 histology (p = 0.03) were predictive of SPTE. On multivariate analysis, only tumor location and size remained statistically significant.
Conclusions
Based on our results, patients at high risk of SPTE can be identified based on patient and tumor characteristics. The best treatment technique in high risk patients is yet to be defined.
