Background

Isolated limb perfusion (ILP) is a regional treatment for patients with melanoma in-transit metastases (ITM) confined to extremities. Reported complete response (CR) rates for ILP varies but is approximately 50–70 %. This study aims to analyze if specific immunological phenotypes could predict CR after ILP.

Methods

132 patients undergoing ILP as a first treatment for melanoma ITM between January 2012 and March 2023 were included. The number and percentage of naïve and memory T and B cell subtypes, and natural killer (NK) cells, were characterized by analyzing pre-operative blood sample using fluorescence activated cell sorting (FACS). Predictive clinical and immunological factors for CR after ILP were analysed using univariable and multivariable analysis.

Results

Response was evaluable in 119 patients (90 %), of which 53 % achieved a CR. After adjusting for age, sex, number of metastases and size of the largest metastasis, immunological factors independently associated with a CR, were percentage of cytotoxic T cells (CD3+8+) (OR 1.07, 95 % CI 1.02–1.13, p = 0.012) and percentage of naive cytotoxic T cells (CD3+8+45RA+) (OR 1.11 95 % CI 1.01–1.22, p = 0.029).

Conclusion

Immunological phenotype described as percentage of cytotoxic T cells and naïve cytotoxic T cells are together with tumor burden important predictive factors for response after ILP for patients with melanoma ITM. This could contribute to better patient selection, individualized treatment algorithms and be a foundation for further research into systemic immunological effects of regional cancer therapies. This includes novel treatment combinations, where an ongoing trial is currently combining ILP with a PD-1 inhibitor (ClinicalTrials.gov NCT03685890).
游离肢体灌注(ILP)是局限于四肢的黑色素瘤转移(ITM)患者的一种局部治疗方法。据报道,ILP的完全缓解率各不相同,但大约为50 - 70%。本研究旨在分析特异性免疫表型是否可以预测ILP后的CR。方法纳入2012年1月至2023年3月期间接受ILP作为黑色素瘤ITM首次治疗的132例患者。采用荧光活化细胞分选法(FACS)分析术前血标本,观察naïve、记忆T、B细胞亚型和自然杀伤(NK)细胞的数量和百分比。采用单变量和多变量分析对ILP后发生CR的临床和免疫预测因素进行分析。结果119例(90%)患者的反应可评估,其中53%达到CR,在调整年龄、性别、转移瘤数量和最大转移瘤大小后,与CR独立相关的免疫因素是细胞毒性T细胞(CD3+8+)百分比(OR 1.07, 95% CI 1.02-1.13, p = 0.012)和初始细胞毒性T细胞(CD3+8+45RA+)百分比(OR 1.11 95% CI 1.01-1.22, p = 0.029)。结论细胞毒性T细胞百分比和naïve细胞毒性T细胞的免疫表型与肿瘤负荷一起是黑色素瘤ITM患者ILP后反应的重要预测因素。这可能有助于更好地选择患者,个性化治疗算法,并为进一步研究局部癌症治疗的系统免疫效应奠定基础。这包括新的治疗组合,目前正在进行的一项试验是将ILP与PD-1抑制剂联合使用(ClinicalTrials.gov NCT03685890)。

Background

Colorectal cancer with peritoneal metastases (PM) presents a significant therapeutic challenge. Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is one option to prolong survival. While completeness of cytoreduction (CC) score 0 is associated with improved outcomes, the clinical value of near-complete CC-score 1 versus open-close laparotomy (CC-3) remains unclear.

Methods

This retrospective study evaluates overall survival (OS) in patients with colorectal cancer PM scheduled for CRS and HIPEC from 23 global peritoneal-surface oncology centers from 2006 to 2023. A propensity score matching was performed using tumor location (colon/rectum), lymph node status, liver metastases, signet-ring histology, preoperative chemotherapy, peritoneal cancer index, and treatment year. Matching was performed using the nearest neighbor method with a caliper of 0.1, chosen after several iterations to optimize intergroup balance. Balance was assessed using standardized mean differences. Sensitivity analyses with alternative calipers and multivariable Cox regression in the unmatched cohort were considered to test the robustness of the findings. The study time-period was divided into 4 equal quartiles for analysis.

Results

In the unmatched cohort (n = 284), patients with CC-1 had significantly longer median OS compared to those with CC-3 (22.2 vs. 9.4 months, p < 0.001). After 1:1 matching (n = 172), the OS advantage of CC-1 persisted, with a median OS of 18.9 months (95 % CI: 14.2–24.7) versus 10.5 months (95 % CI: 9.4–12.3) for CC-3, p < 0.0001, HR 0.4 (95 % CI:0.27–0.56). Multivariable Cox regression confirmed CC-1 as a significant predictor of survival (HR: 0.15, 95 % CI: 0.08–0.26). The CC-1 proportion went from 55 to 65 % in time-periods 1 & 2–39 % in period 3, to 11 % in period 4; leading to significantly reduced survival rates in the latter time-periods 3 & 4.

Discussion

Near complete cytoreduction is associated with improved overall survival compared to open-close laparotomy. Prospective or standardized multicenter analyses will be required to confirm the clinical value of a near complete cytoreduction.
结直肠癌伴腹膜转移(PM)是一个重大的治疗挑战。细胞减少手术(CRS)联合腹腔热化疗(HIPEC)是延长生存期的一种选择。虽然细胞减少完整性(CC)评分0与预后改善相关,但接近完全的CC评分1与开合式剖腹手术(CC-3)的临床价值尚不清楚。方法本回顾性研究评估2006年至2023年全球23个腹膜表面肿瘤中心计划进行CRS和HIPEC的结直肠癌PM患者的总生存期(OS)。根据肿瘤位置(结肠/直肠)、淋巴结状态、肝转移、印戒组织学、术前化疗、腹膜癌指数和治疗年份进行倾向评分匹配。采用最近邻法进行匹配,卡尺为0.1,经过多次迭代选择以优化组间平衡。使用标准化平均差异评估平衡。在未匹配的队列中考虑使用替代卡尺和多变量Cox回归进行敏感性分析,以检验结果的稳健性。将研究时间段分成4个相等的四分位数进行分析。结果在未匹配的队列中(n = 284), CC-1患者的中位生存期明显长于CC-3患者(22.2个月vs 9.4个月,p < 0.001)。1:1匹配(n = 172)后,CC-1的生存优势持续存在,中位生存期为18.9个月(95% CI: 14.2-24.7),而CC-3的中位生存期为10.5个月(95% CI: 9.4-12.3), p < 0.0001, HR 0.4 (95% CI: 0.27-0.56)。多变量Cox回归证实CC-1是生存率的重要预测因子(HR: 0.15, 95% CI: 0.08-0.26)。CC-1的比例从第1阶段的55%上升到65%,第3阶段为39%,第4阶段为11%;导致后期存活率显著降低3 &;与开合剖腹手术相比,接近完全的细胞减少与总生存率的提高有关。需要前瞻性或标准化的多中心分析来确认接近完全细胞减少的临床价值。

Background

Complete cytoreductive surgery (CRS) performed in expert centers is a key determinant of outcome in patients with colorectal peritoneal metastases (CRPM). In the contemporary context of ongoing debate regarding the role of HIPEC following the PRODIGE 7 trial, the impact of initial management outside expert centers on outcomes remains insufficiently characterized. This study evaluates the value of systematic second-look surgeries in expert centers after CRS in non-expert centers.

Methods

Patients with histologically confirmed CRPM who initially underwent surgery in non-expert centers followed by systematic second-look surgery in two expert centers were included between 2010 and 2022.

Statistical analysis

Perioperative outcomes were evaluated in both surgeries. Preoperative imaging (CT-scan/MRI) were conducted before second-look surgeries and reviewed by expert radiologists. Survival outcomes were performed by Kaplan-Meier method.

Results

Among 106 patients (50.9 % male, mean age 58.9 ± 10.8 years), all tumors were classified as pT3-4, with 87 % having synchronous CRPM. Initial CRS in non-expert centers was performed urgently in 35 % of cases, primarily due to occlusion or perforation (62.1 %). Complete cytoreduction (CC0) was declared in 63 % of initial CRS. Reassessment (CT/MRI) before second-look was highly predictive of intraoperative and histological presence of CRPM, but intraoperative CRPM detection occurred in 61 % (CT-negative) and 81 % (MRI-negative) with histological confirmation in 53 % and 42 %. During second-look surgery, CRPM was observed in 88 % of cases (median PCI score:6) and 11.3 % were unresectable. Median overall survival (OS) was 43 months with 1- and 5-year OS of 95 % and 34.3 %, respectively. Prognostic factors of lower OS included poorly cohesive histology, emergency surgery and incomplete cytoreduction during first surgery in non-expert centers.

Conclusions

In patients with CRPM initially managed in non-expert centers, expert-center reassessment, including consideration of second-look surgery, identifies persistent or recurrent peritoneal disease in a substantial proportion of patients, even in the absence of radiological evidence. These findings support the importance of early referral to expert centers for comprehensive evaluation and multidisciplinary decision-making. The impact of second-look strategies on survival outcomes warrants further prospective investigation.
背景:在专家中心进行的完全细胞减少手术(CRS)是决定结直肠腹膜转移(CRPM)患者预后的关键因素。在当前关于在PRODIGE 7试验后HIPEC作用的争论中,专家中心以外的初始管理对结果的影响仍然没有充分的描述。本研究评估专家中心在非专家中心进行CRS后系统的二次手术的价值。方法纳入2010年至2022年间在非专家中心接受手术,随后在两家专家中心进行系统复诊手术的组织学证实的CRPM患者。统计分析两种手术的围手术期结局。术前影像学检查(ct扫描/MRI)在复诊手术前进行,并由放射科专家检查。生存结果采用Kaplan-Meier法。结果106例患者(男性50.9%,平均年龄58.9±10.8岁),肿瘤均为pT3-4级,87%为同步CRPM。在非专家中心的初始CRS在35%的病例中紧急进行,主要是由于闭塞或穿孔(62.1%)。在初始CRS中,63%的患者宣布完全细胞减少(CC0)。复诊前的重新评估(CT/MRI)对术中和组织学上CRPM的存在有很高的预测作用,但术中CRPM的检出率为61% (CT阴性)和81% (MRI阴性),组织学证实为53%和42%。在复诊手术中,88%的病例出现了CRPM (PCI中位评分:6),11.3%的病例无法切除。中位总生存期(OS)为43个月,1年和5年生存率分别为95%和34.3%。较低OS的预后因素包括组织学内聚不良、急诊手术和在非专家中心首次手术时细胞减少不完全。结论:对于最初在非专家中心治疗的CRPM患者,专家中心重新评估,包括考虑二次手术,即使在没有放射证据的情况下,也能确定相当比例的患者持续或复发性腹膜疾病。这些发现支持早期转诊到专家中心进行综合评估和多学科决策的重要性。复诊策略对生存结果的影响值得进一步的前瞻性研究。

Background

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS–HIPEC) is technically complex and resource-intensive. The primary objective of this study was to perform a detailed micro-costing analysis of CRS–HIPEC. As a secondary, exploratory objective, we evaluated whether adherence to an Enhanced Recovery After Surgery (ERAS) pathway was associated with differences in postoperative resource utilisation and direct hospital costs.

Materials and methods

A retrospective observational analysis was conducted on all consecutive CRS–HIPEC procedures performed from 2021 to 2023 in a Spanish tertiary public centre. Resource use and cost determinants were assessed using micro-costing methods. An exploratory comparison between ERAS and non-ERAS management periods was performed.

Results

The median cost of CRS–HIPEC was €26,386. Higher expenditure was associated with longer hospital stays, higher PCI scores, need for anastomosis and infectious complications. ERAS and non-ERAS cohorts showed similar case complexity. Despite partial implementation, ERAS adherence was associated with shorter median hospital stay (8 vs 13 days, p < 0.001) and lower total median costs (€20,452.5 vs €27,346.7, p = 0.02), without an increase in severe postoperative complications (Clavien–Dindo ≥ III: 17.2 % vs 25.0 %, p = 0.454). The multivariable model (including PCI, anastomosis and severe complications) showed good discriminative performance for identifying high-cost cases (AUC = 0.923; 95 % CI 0.851–0.976).

Conclusions

CRS–HIPEC costs are predominantly driven by hospital stay and complication-related resource utilisation. The exploratory ERAS analysis suggests that even partial adherence may reduce postoperative stay and costs without increasing morbidity. These findings highlight the importance of perioperative optimisation to improve the clinical and economic efficiency of CRS–HIPEC programmes.
背景:细胞减少手术联合腹腔热化疗(CRS-HIPEC)技术复杂且资源密集。本研究的主要目的是对CRS-HIPEC进行详细的微观成本分析。作为次要的探索性目标,我们评估了术后增强恢复(ERAS)途径的依从性是否与术后资源利用和直接住院费用的差异相关。材料和方法回顾性观察分析了2021年至2023年在西班牙三级公共中心连续进行的所有CRS-HIPEC手术。使用微观成本法评估了资源使用和成本决定因素。对ERAS和非ERAS管理期进行探索性比较。结果CRS-HIPEC的中位成本为26386欧元。较高的费用与较长的住院时间、较高的PCI评分、吻合需求和感染并发症相关。ERAS组和非ERAS组的病例复杂性相似。尽管部分实施,ERAS依从性与较短的中位住院时间(8天vs 13天,p < 0.001)和较低的总中位成本(20,452.5欧元vs 27,346.7欧元,p = 0.02)相关,且没有增加严重的术后并发症(Clavien-Dindo≥III: 17.2% vs 25.0%, p = 0.454)。多变量模型(包括PCI、吻合、严重并发症)对高成本病例的鉴别效果较好(AUC = 0.923; 95% CI 0.851-0.976)。结论scrs - hipec费用主要受住院时间和并发症相关资源利用的影响。探索性ERAS分析表明,即使部分依从性也可以减少术后住院时间和费用,而不会增加发病率。这些发现强调了围手术期优化对提高CRS-HIPEC方案的临床和经济效率的重要性。

Empirical evidence shows that treatment of adult soft tissue sarcoma (STS) according to clinical guidelines has a survival benefit for patients. In 2021, the first evidence-based guidelines for STS were published in Germany including 14 measurable quality indicators (QIs). This paper examines the quality of care of STS in Germany across all treatment institutions prior to the publication of the clinical guideline using the QIs.
A comprehensive population-based cohort of 20,922 sarcoma patients from 11 of 16 federal states, diagnosed between 2015 and 2021 was extracted from the cancer registry data using the ICD-O-3-codes for topography and histological subtype. The QI measurements are based on the calculation rules of a group of experts. Annual percentage changes (APCs) were calculated to identify trends over time.
QI 1 (Pre-therapeutic presentation in the tumor board (initial diagnosis of STS)) increased from 9 % to 24 %. QI 7 (R0 resection for STS) showed a stable rate of over 80 %. For QI 8 (hysterectomy without morcellation for sarcoma confined to the uterus), the rate was 82 % in 2015 and rose significantly until 2017 to 94 %. QI 12 (First-line chemotherapy for STS without GIST) remained at the same level as the overall value of 79 %. For QI 14 (Postoperative mortality in retroperitoneal sarcoma), the value for the entire period was 1.4 %.
The extensive database enables QI analysis for sarcoma care. Improvements in defined QIs confirm progress, while unmet targets are identifiable. Using cancer-registry data ensures comprehensive coverage of all institutions treating sarcoma patients, extending beyond accredited sarcoma centers. Results may serve as baseline values for future evaluations of improvements in patient care following implementation of the S3 guideline.
经验证据表明,根据临床指南治疗成人软组织肉瘤(STS)对患者的生存有好处。2021年,德国发布了首个基于证据的STS指南,其中包括14个可测量的质量指标(QIs)。本文研究了德国所有治疗机构在临床指南发布之前使用QIs的STS护理质量。使用地形和组织学亚型的icd - o -3代码从癌症登记数据中提取了2015年至2021年间诊断的来自16个联邦州中的11个州的20,922例肉瘤患者的综合人群队列。QI测量是基于一组专家的计算规则。计算年度百分比变化(APCs)以确定随时间变化的趋势。QI 1(治疗前肿瘤表现(最初诊断为STS))从9%增加到24%。QI 7 (R0切除STS)稳定率在80%以上。QI 8(局限于子宫的肉瘤的子宫切除术不分块)的比例在2015年为82%,到2017年显著上升至94%。QI 12(无GIST的STS的一线化疗)保持在与总体值79%相同的水平。对于QI 14(腹膜后肉瘤的术后死亡率),整个期间的数值为1.4%。广泛的数据库使QI分析能够用于肉瘤护理。已定义的质量指标的改进确认了进展,而未达到的目标是可识别的。使用癌症登记数据确保全面覆盖所有治疗肉瘤患者的机构,扩展到认可的肉瘤中心之外。结果可以作为实施S3指南后患者护理改善的未来评估的基线值。

Objectives

Multiple studies have demonstrated that segmentectomy is feasible and can yield long-term outcomes comparable to lobectomy for selected central non-small cell lung cancer (NSCLC). This study aimed to identify factors influencing the feasibility of segmentectomy for central NSCLC, and to develop a predictive nomogram.

Methods

Patients with central NSCLC ≤2 cm who underwent segmentectomy or lobectomy between 2020 and 2024 were screened. Patients were split into two groups based on their surgical date (Training set: 2020–2023 and Validation set: 2024). The least absolute shrinkage and selection operator (LASSO) regression and multivariable logistic regression analyses were performed to identify potential predictors. Qualified segmentectomy (surgical margin ≥ maximum tumor diameter) was classified as 0, while lobectomy or unqualified segmentectomy was classified as 1. A nomogram was developed based on these identified predictors.

Results

There were 303 and 105 patients in the training set and validation set, respectively. The probability of achieving sufficient margins during segmentectomy was 83.9 % in the training set and 81.3 % in the validation set. After LASSO and multivariable logistic regression analyses, four variables were retained: tumor size (OR = 3.81, P = 0.006), radiological type (solid vs. subsolid, OR = 5.39, P = 0.009), tumor-to-segmental bronchus distance (OR = 0.64, P = 0.036), and number of tumor-involved subsegments (OR = 1.54, P < 0.001). The nomogram developed from these predictors exhibited good predictive ability, with an area under the curve of 0.793 in the training set and 0.777 in the validation set.

Conclusions

Tumor size, radiological type, tumor-to-segmental bronchus distance, and number of tumor-involved subsegments influenced the feasibility of segmentectomy for central NSCLC.
多项研究表明,对于某些中枢性非小细胞肺癌(NSCLC),节段切除术是可行的,并且可以产生与肺叶切除术相当的长期结果。本研究旨在确定影响中枢性非小细胞肺癌节段切除术可行性的因素,并建立预测图。方法筛选2020 - 2024年间行节段切除术或肺叶切除术的中枢性NSCLC≤2 cm患者。患者根据手术日期分为两组(训练集:2020-2023年,验证集:2024年)。采用最小绝对收缩和选择算子(LASSO)回归和多变量逻辑回归分析来确定潜在的预测因子。合格节段切除术(手术切缘≥最大肿瘤直径)评分为0,肺叶切除术或不合格节段切除术评分为1。基于这些确定的预测因子,开发了一个nomogram。结果训练集和验证集分别有303例和105例患者。在训练集和验证集中,获得足够切缘的概率分别为83.9%和81.3%。LASSO和多变量logistic回归分析后,保留了四个变量:肿瘤大小(OR = 3.81, P = 0.006)、放射学类型(实性vs.亚实性,OR = 5.39, P = 0.009)、肿瘤到支气管段的距离(OR = 0.64, P = 0.036)和肿瘤累及的亚段数量(OR = 1.54, P < 0.001)。由这些预测因子形成的nomogram具有较好的预测能力,训练集的曲线下面积为0.793,验证集的曲线下面积为0.777。结论肿瘤大小、影像学类型、肿瘤到支气管节段的距离、肿瘤累及的亚节段数量影响中枢性非小细胞肺癌节段切除术的可行性。

Purpose

Identifying high-risk patients for late recurrence is crucial for optimizing extended endocrine therapy (EET). This study investigated how clinicopathologic predictors of late recurrence diverge according to menopausal status in estrogen receptor (ER)-positive breast cancer patients who completed 5-year endocrine therapy.

Methods

We retrospectively analyzed 1549 patients with stage I–III ER-positive breast cancer who completed 5 years of endocrine therapy and remained recurrence-free during that period. Median follow-up was 14.7 years. Outcomes included distant metastasis-free survival (DMFS) and overall survival (OS). Analyses were stratified by menopausal status to identify status-specific risk factors.

Results

During the follow-up period, 208 patients (13.4 %) experienced late recurrence, with distant metastasis (6.3 %) being the most frequent event. Kaplan–Meier analyses demonstrated that tumor size >2 cm and higher nodal stage were significantly associated with inferior DMFS and OS in both subgroups (all P < .05). However, multivariable analysis revealed distinct prognostic patterns according to menopausal status. In premenopausal women, nodal involvement was the most potent driver of late recurrence; N1 stage significantly increased the risk of poor DMFS (HR 3.14, 95 % CI 1.54–6.40; P = .002) and OS (HR 3.39, 95 % CI 1.45–7.93; P = .005). Furthermore, age at diagnosis showed a significant inverse association with distant metastasis risk, with each one-year decrease in age increasing the risk by 6 % (HR 0.94; P = .019). In contrast, for postmenopausal patients, tumor size (>2 cm) emerged as the predominant predictor for both DMFS (HR 2.70; P = .006) and OS (HR 2.26; P = .039), whereas the prognostic impact of nodal stage was notably diminished (N1: P = .374 for DMFS; P = .999 for OS). In this group, older age was independently associated with worse OS (HR 1.13; P < .001) but did not significantly impact DMFS.

Conclusion

Predictors for late recurrence are different depending on menopausal status: nodal burden and young age dominate in premenopausal patients, whereas tumor size is more critical in postmenopausal patients. These findings suggest that menopausal status must be a primary consideration in risk-stratification models for EET and long-term surveillance.
目的鉴别晚期复发的高危患者是优化延长内分泌治疗(EET)的关键。本研究探讨了雌激素受体(ER)阳性乳腺癌患者在完成5年内分泌治疗后,其晚期复发的临床病理预测因子如何根据绝经状态发生差异。方法回顾性分析1549例I-III期er阳性乳腺癌患者,这些患者完成了5年的内分泌治疗,在此期间没有复发。中位随访时间为14.7年。结果包括远端无转移生存期(DMFS)和总生存期(OS)。分析按绝经状态分层,以确定特定状态的危险因素。结果随访期间,晚期复发208例(13.4%),远处转移发生率最高(6.3%)。Kaplan-Meier分析显示,两个亚组的肿瘤大小和较高的淋巴结分期与较差的DMFS和OS显著相关(均P <; 0.05)。然而,多变量分析显示不同的预后模式根据绝经状态。在绝经前妇女中,淋巴结受累是晚期复发最有力的驱动因素;N1期显著增加DMFS (HR 3.14, 95% CI 1.54-6.40; P = 0.002)和OS (HR 3.39, 95% CI 1.45-7.93; P = 0.005)的不良风险。此外,诊断年龄与远处转移风险呈显著负相关,年龄每降低一年风险增加6% (HR 0.94; P = 0.019)。相比之下,对于绝经后患者,肿瘤大小(>2 cm)成为DMFS (HR 2.70; P = 0.006)和OS (HR 2.26; P = 0.039)的主要预测因素,而淋巴结分期对预后的影响显著降低(DMFS的N1: P = 0.374; OS的P = 0.999)。在该组中,年龄较大与较差的OS独立相关(HR 1.13; P < .001),但对DMFS没有显著影响。结论不同绝经期患者晚期复发的预测因素不同:绝经前患者的淋巴结负担和年龄占主导地位,而绝经后患者的肿瘤大小更为重要。这些发现表明,在EET风险分层模型和长期监测中,绝经状态必须是一个主要考虑因素。

Introduction

Patients' and physicians' expectations may not always align, which can potentially impact postoperative quality of life. We evaluated the extent to which expectations of well-being and treatment-related information were fulfilled. We also examined its impact on the immediate and short-term quality of life following surgery in breast cancer patients.

Methods

We prospectively followed a cohort of non-pregnant breast cancer patients who underwent surgery and had no history of breast reconstruction, prophylactic, palliative, or intensive care admission (n = 100). Expectations and the initial quality-of-life assessment were collected during the first follow-up visit, with a second measurement conducted by phone one month later. Ordinal multiple logistic regression was used, and Odds Ratios (ORs) and 95 % Confidence Intervals (CIs) were estimated.

Results

Physical, treatment-response, and emotional well-being expectations were largely unformed, while social well-being expectations were mostly underestimated or fulfilled as high as expected. Underestimation reduced the odds of good immediate physical well-being (OR 0.12, 95 % CI 0.02, 0.54). Also, underestimation reduced the odds of good immediate and short-term emotional well-being (OR 0.03, 95 % CI 0.01, 0.14 and OR 0.03, 95 % CI 0.01, 0.17, respectively). Meeting expectations as high as anticipated or receiving more social support than expected increased the odds of immediate and short-term social well-being.

Conclusions

Unformed expectations were prevalent, except in social well-being. Not meeting expectations harmed physical and emotional well-being, while meeting them benefited social well-being. Providing information about surgical treatment is crucial for setting clear and realistic expectations.
患者和医生的期望可能并不总是一致的,这可能会影响术后的生活质量。我们评估了对健康和治疗相关信息的期望达到的程度。我们还研究了它对乳腺癌患者手术后即刻和短期生活质量的影响。方法前瞻性随访一组接受手术、无乳房重建史、无预防性、无姑息治疗史、无重症监护史的非妊娠乳腺癌患者(n = 100)。期望和最初的生活质量评估在第一次随访期间收集,一个月后通过电话进行第二次测量。采用有序多元逻辑回归,估计优势比(ORs)和95%置信区间(ci)。结果身体健康、治疗反应和情绪健康期望基本未形成,而社会健康期望大多被低估或达到预期的高度。低估降低了良好的即时身体健康的几率(OR 0.12, 95% CI 0.02, 0.54)。此外,低估降低了即时和短期良好情绪健康的几率(分别为OR 0.03, 95% CI 0.01, 0.14和OR 0.03, 95% CI 0.01, 0.17)。达到与预期一样高的期望或获得比预期更多的社会支持,增加了即时和短期社会福祉的几率。结论除社会福利外,形成的期望普遍存在。不满足期望会损害身体和情感健康,而满足期望则有利于社会健康。提供有关手术治疗的信息对于设定明确和现实的期望至关重要。

Background

Pelvic exenteration (PE) is a highly invasive but potentially curative surgery for advanced or recurrent pelvic malignancies. Although postoperative complications are a concern due to their invasiveness, their influence on oncological outcomes remains unclear.

Methods

We conducted a multi-institutional retrospective cohort study involving 261 patients who underwent PE with curative intent between 2012 and 2022. Patients were classified into exposure (Clavien-Dindo grade ≥3 complications within 30 days postoperatively) and control groups. The primary and secondary endpoints were recurrence-free survival (RFS) and overall survival (OS), respectively. Propensity score weighting (standardized mortality ratio weights) was employed to adjust for 20 baseline covariates across patient, tumor, and surgical characteristics.

Results

After adjustment, no statistically significant difference was observed in RFS between patients with and without Clavien-Dindo grade ≥3 complications (adjusted hazard ratio [HR]: 1.34; 95 % confidence interval [CI]: 0.78–2.29; P = 0.29). Similarly, no significant association was found for OS (adjusted HR, 1.32; 95 % CI: 0.69–2.55; P = 0.29). Subgroup analyses by PE type (total PE vs. anterior PE/posterior PE) and sensitivity analyses for surgical site infections and Clavien-Dindo grade ≥2 complications showed consistent results.

Conclusions

In this large PE cohort with detailed clinical data and advanced statistical adjustments, major postoperative complications were not significantly associated with poor long-term oncological outcomes. Although a modest effect cannot be ruled out, and efforts must be made to avoid complications, PE remains a viable treatment option despite being highly invasive.
背景:盆腔切除(PE)是治疗晚期或复发性盆腔恶性肿瘤的一种高侵入性但具有潜在疗效的手术。虽然术后并发症由于其侵袭性而引起关注,但其对肿瘤预后的影响尚不清楚。方法:我们进行了一项多机构回顾性队列研究,涉及261名在2012年至2022年间接受PE治疗的患者。患者分为暴露组(术后30天内Clavien-Dindo分级≥3次并发症)和对照组。主要终点和次要终点分别为无复发生存期(RFS)和总生存期(OS)。倾向评分加权(标准化死亡率权重)用于调整患者、肿瘤和手术特征的20个基线协变量。结果:校正后,有无Clavien-Dindo级≥3级并发症患者的RFS差异无统计学意义(校正风险比[HR]: 1.34; 95%可信区间[CI]: 0.78-2.29; P = 0.29)。同样,OS也没有明显的相关性(调整后的HR, 1.32; 95% CI: 0.69-2.55; P = 0.29)。按PE类型(全PE vs前PE/后PE)进行亚组分析,对手术部位感染和Clavien-Dindo级≥2级并发症进行敏感性分析,结果一致。结论:在这个具有详细临床数据和先进统计调整的大型PE队列中,主要术后并发症与不良的长期肿瘤预后无显著相关性。尽管不能排除一定的影响,并且必须努力避免并发症,尽管PE具有高度侵入性,但仍然是一种可行的治疗选择。

Background

Frailty is a stronger determinant of surgical outcomes in colorectal cancer (CRC) than chronological age. Yet frail patients are often excluded from studies, and their long-term outcomes remain poorly defined. Most research dichotomizes patients as frail or non-frail, leaving the gradation of frailty (mild, moderate, severe) underexplored.

Methods

Prospective, single-center study (2017–2023) including 1028 consecutive CRC patients evaluated for curative treatment. Frailty was screened with PRISMA-7 and stratified using the IF-VIG index. Allocation to surgery or non-operative care followed multidisciplinary assessment. Primary outcomes were 30-day morbidity and mortality; secondary outcomes included length of stay, readmission, and survival.

Results

Frailty was identified in 115 patients (11.2 %): 38 mild, 26 moderate, and 9 severe. Forty-one frail patients (mainly mild) underwent surgery, while 74 (mostly moderate-to-severe) received non-operative care. Compared with non-frail surgical patients (n = 913), frail patients had similar surgical complication rates (22.7 % vs 21.6 %) and no 30-day mortality, but longer stays (median 9.2 vs 6.8 days; p = 0.018), more medical complications (14.6 % vs 6.6 %; p < 0.001), and higher readmission (15.9 %). At 45 months, mortality was higher in frail surgical patients (69 % vs 19 %; HR 4.2, 95 % CI 2.8–6.3). Within the frail cohort, surgery improved survival over non-operative care (HR 0.62, 95 % CI 0.41–0.95).

Conclusions

Stratifying frailty into mild, moderate, and severe provides practical guidance for CRC management. Mildly frail patients, when optimized, can achieve outcomes comparable to non-frail individuals, while moderate-to-severe frailty often precludes surgery. Routine frailty stratification should inform individualized decisions and guide future trials in severely frail patients.
背景:与实足年龄相比,虚弱是结直肠癌(CRC)手术结果的一个更强的决定因素。然而,体弱多病的患者经常被排除在研究之外,他们的长期预后仍然不明确。大多数研究将患者分为虚弱或非虚弱,而没有对虚弱程度(轻度、中度、重度)进行深入研究。方法前瞻性单中心研究(2017-2023),纳入1028例连续CRC患者,评估其治愈性治疗。用PRISMA-7筛选脆性,并用IF-VIG指数分层。在多学科评估后分配手术或非手术治疗。主要结局是30天的发病率和死亡率;次要结局包括住院时间、再入院和生存。结果115例(11.2%)患者出现虚弱,其中轻度38例,中度26例,重度9例。41例体弱患者(主要是轻度)接受了手术治疗,74例(主要是中重度)接受了非手术治疗。与非体弱的手术患者(n = 913)相比,体弱患者的手术并发症发生率相似(22.7% vs 21.6%),没有30天死亡率,但住院时间较长(中位9.2 vs 6.8天;p = 0.018),并发症较多(14.6% vs 6.6%; p < 0.001),再入院率较高(15.9%)。45个月时,体弱手术患者的死亡率更高(69% vs 19%; HR 4.2, 95% CI 2.8-6.3)。在虚弱的队列中,手术比非手术治疗提高了生存率(HR 0.62, 95% CI 0.41-0.95)。结论将衰弱分为轻度、中度和重度,对结直肠癌的治疗具有实际指导意义。轻度虚弱的患者,经过优化后,可以获得与非虚弱个体相当的结果,而中度至重度虚弱的患者通常无法进行手术。常规虚弱分层应该为个性化决策提供信息,并指导未来在严重虚弱患者中的试验。
