    背景:主动监测(AS)是低风险前列腺癌(LRPC)的首选策略;但是,关于AS采用的决定因素的数据有限,尤其是黑人。
    方法:从2014年1月至2017年6月,新诊断的LRPC≤75岁的黑人和白人患者通过Metro-Detroit和Georgia基于人群的癌症登记处进行鉴定,并完成一项调查,评估影响AS摄取的因素。
    结果:在1688名研究参与者中,57%的人选择了AS(51%的黑人参与者,61%的白色)超过最终治疗。在未经调整的分析中,与初始AS摄取相关的患者因素包括年龄较大,白人种族,和高等教育。然而,在调整协变量后,这些因素均不是AS摄取的显著预测因子。AS摄取的最强决定因素是泌尿科医师推荐的AS(调整后的患病率比率,6.59,95%CI,4.84-8.97)。与接受AS的决定相关的其他因素包括共同的患者-医生治疗决定,更多的前列腺癌知识,与佐治亚州相比,底特律地铁和住宅。相反,那些决定受到“治愈”或“寿命更长”的渴望强烈影响的男性,以及那些认为他们的LRPC诊断更严重的男性,选择AS的可能性较小。
    结论:在这个当代样本中,大多数新诊断的LRPC患者选择了AS。尽管他们的泌尿科医生的投入非常有影响力,一些患者的决策和心理因素与AS摄取独立相关.这些数据为可能改变的因素提供了新的思路,这些因素可以帮助进一步增加LRPC患者的AS摄取。
    BACKGROUND: Active surveillance (AS) is the preferred strategy for low-risk prostate cancer (LRPC); however, limited data on determinants of AS adoption exist, particularly among Black men.
    METHODS: Black and White newly diagnosed (from January 2014 through June 2017) patients with LRPC ≤75 years of age were identified through metro-Detroit and Georgia population-based cancer registries and completed a survey evaluating factors influencing AS uptake.
    RESULTS: Among 1688 study participants, 57% chose AS (51% of Black participants, 61% of White) over definitive treatment. In the unadjusted analysis, patient factors associated with initial AS uptake included older age, White race, and higher education. However, after adjusting for covariates, none of these factors was significant predictors of AS uptake. The strongest determinant of AS uptake was the AS recommendation by a urologist (adjusted prevalence ratio, 6.59, 95% CI, 4.84-8.97). Other factors associated with the decision to undergo AS included a shared patient-physician treatment decision, greater prostate cancer knowledge, and residence in metro-Detroit compared with Georgia. Conversely, men whose decision was strongly influenced by the desire to achieve \"cure\" or \"live longer\" with treatment and those who perceived their LRPC diagnosis as more serious were less likely to choose AS.
    CONCLUSIONS: In this contemporary sample, the majority of patients with newly diagnosed LRPC chose AS. Although the input from their urologists was highly influential, several patient decisional and psychological factors were independently associated with AS uptake. These data shed new light on potentially modifiable factors that can help further increase AS uptake among patients with LRPC.

    背景:我们试图评估处于疾病进展中到高风险的局部前列腺癌(PCa)幸存者的患者护理体验(PCE)的城乡差异。
    方法:使用2007-2015年监测流行病学和最终结果(SEER)数据与医疗保健提供者和系统的医疗保险消费者评估(CAHPS)调查相关,我们分析了诊断后≥6个月的幸存者\'首次调查.使用协变量调整线性回归来估计治疗状态的关联(确定性治疗与无)和住宅(大型地铁vs.地铁vs.农村)与PCE综合和评级措施。
    结果:在3779名PCa幸存者中,1798(53.2%)和370(10.9%)居住在大型地铁和农村地区,分别;更多的农村(与大型地铁)居民未经治疗(21.9%vs.16.7%;p=0.017)。未治疗(与治疗)PCa幸存者报告医生沟通得分较低(β=-2.0;p=0.022),专家评级(β=-2.5;p=0.008),和总体护理评级(β=-2.4;p=0.006)。Whiletreatedruralsurvivorsgavehigher(β=3.6;p=0.022)scoresforobtainingneededcare,未经治疗的农村幸存者获得所需护理的得分较低(β=-7.0;p=0.017),健康计划评分较低(β=-7.9;p=0.003)。
    结论:农村PCa幸存者接受治疗的可能性较小。PCEs的城乡差异因治疗状况而异。
    BACKGROUND: We sought to evaluate rural-urban disparities in patient care experiences (PCEs) among localized prostate cancer (PCa) survivors at intermediate-to-high risk of disease progression.
    METHODS: Using 2007-2015 Surveillance Epidemiology and End Results (SEER) data linked to Medicare Consumer Assessment of Healthcare Providers and Systems (CAHPS) surveys, we analyzed survivors\' first survey ≥6 months post-diagnosis. Covariate adjusted linear regressions were used to estimate associations of treatment status (definitive treatment vs. none) and residence (large metro vs. metro vs. rural) with PCE composite and rating measures.
    RESULTS: Among 3779 PCa survivors, 1798 (53.2%) and 370 (10.9%) resided in large metro and rural areas, respectively; more rural (vs. large metro) residents were untreated (21.9% vs. 16.7%; p = 0.017). Untreated (vs. treated) PCa survivors reported lower scores for doctor communication (ß = -2.0; p = 0.022), specialist rating (ß = -2.5; p = 0.008), and overall care rating (ß = -2.4; p = 0.006). While treated rural survivors gave higher (ß = 3.6; p = 0.022) scores for obtaining needed care, untreated rural survivors gave lower scores for obtaining needed care (ß = -7.0; p = 0.017) and a lower health plan rating (ß = -7.9; p = 0.003) compared to their respective counterparts in large metro areas.
    CONCLUSIONS: Rural PCa survivors are less likely to receive treatment. Rural-urban differences in PCEs varied by treatment status.

    Background Anal squamous cell carcinoma accounts for less than 2-3% of all digestive system carcinomas. The present study aimed to determine the clinical characteristics, treatment patterns, and treatment outcomes of patients at our institution. Methodology We reviewed the clinical data of all consecutive patients with anal squamous cell carcinoma who were treated with definitive radiotherapy in our department between July 2009 and July 2020. Radiotherapy was delivered in 1.8-2 Gy daily fractions to a whole pelvic dose ranging from 45 to 50 Gy, followed by boost radiotherapy of 10-15 Gy, resulting in a total dose of approximately 60 Gy. Concurrent chemotherapy with radiotherapy included 5-fluorouracil/mitomycin C or 5-fluorouracil/cisplatin. Results A total of 14 patients with a median age of 61.5 years (range: 45-85 years) were analyzed. There were nine women and five men. The clinical T stage was T1 in two patients, T2 in six patients, T3 in two patients, and T4 in four patients. The clinical N stage was N0 in four patients and N1 in 10 patients. Patients with clinical stage III disease comprised 79% of the entire study population. For the entire cohort, the five-year overall survival rate was 83.3% and the five-year progression-free survival rate was 48.5%. One patient experienced grade 3 fecal incontinence, and the others experienced no radiation-induced severe delayed adverse events. Conclusions The results of our study demonstrated that definitive radiotherapy with or without chemotherapy for patients with anal squamous cell carcinoma is an effective and feasible treatment.

    局部晚期头颈部鳞状细胞癌(HNSCC)的明确放化疗可实现较高的局部肿瘤控制率;但通常与长期毒性相关。未来的方向可能是集中于治疗体积而不是放射治疗剂量的降阶梯策略。该分析评估了在临床试验背景下使用标准轮廓方法治疗的患者的放射治疗剂量和体积参数,与修改后的体积减少轮廓方法相比。在这种情况下,在该分析中包括来自在单个研究中心治疗的CheckRad-CD8试验的30名连续患者。在放疗结束时评估治疗毒性和生活质量。根据用于患者治疗的现有技术轮廓指南的标准治疗计划(ST)和根据修订的模拟方法的体积减少治疗计划(VRT),对每位患者进行计算。比较了38个危险器官的计划目标体积(PTV)和平均剂量。放疗结束时,患者报告粘膜炎的发生率很高;吞咽困难和口干症。此外,患者报告通过EORTCQLQ-HN35问卷评估的生活质量恶化。比较两种轮廓方法;VRT组的选择性PTV_56Gy和高风险PTV_63Gy(缩小场)明显较小。口腔结构的平均剂量显着减少;在模拟的VRT计划中实现了喉以及部分吞咽肌肉和下颌下腺。通过减少辐照体积来降低治疗强度可能潜在地减少对有风险器官的治疗体积和平均剂量。建议的轮廓方法应在临床试验的背景下进一步研究。
    Definitive radiochemotherapy of locally advanced head and neck squamous cell cancer (HNSCC) achieves high locoregional tumor control rates; but is frequently associated with long-term toxicity. A future direction could be a de-escalation strategy focusing on treated volume rather than radiotherapy dose. This analysis evaluates radiotherapy dose and volume parameters of patients treated with a standard contouring approach in a clinical trial context compared with a revised volume-reduced contouring approach. In this case, 30 consecutive patients from the CheckRad-CD8 trial treated at a single study center were included in this analysis. Treatment toxicity and quality of life were assessed at the end of radiotherapy. Standard treatment plans (ST) following state of the art contouring guidelines that were used for patient treatment and volume reduced treatment plans (VRT) according to a revised simulated approach were calculated for each patient. Planning target volumes (PTV) and mean doses to 38 organs-at-risk structures were compared. At the end of radiotherapy patients reported high rates of mucositis; dysphagia and xerostomia. In addition; patient reported quality of life as assessed by the EORTC QLQ-HN35 questionnaire deteriorated. Comparing the two contouring approaches; the elective PTV_56 Gy and the high risk PTV_63 Gy (shrinking field) were significantly smaller in the VRT group. Significant reduction of mean dose to structures of the oral cavity; the larynx as well as part of the swallowing muscles and the submandibular glands was achieved in the simulated VRT-plan. Treatment de-intensification by reduction of the irradiated volume could potentially reduce treatment volume and mean doses to organs at risk. The proposed contouring approach should be studied further in the context of a clinical trial.

    Head and neck cancer (HNC) treatment-related morbidity can be detrimental to quality of life (QOL). Myosteatosis is associated with poor QOL in multiple cancers. If predictive of poor QOL trajectories, myosteatosis would be a tool for clinicians to determine which patients may require additional support during treatment. The purpose of this study was to determine if pretreatment myosteatosis is associated with a poor QOL trajectory following treatment completion.
    METHODS: In a retrospective cohort design, myosteatosis was determined from pretreatment CT scans. Both physical and global QOL score was assessed through patient interview on follow-up appointment. Demographic, cancer-specific, and social covariates were collected, reported, and considered as potential confounders.
    RESULTS: The population of 163 patients was mostly male (82.2%) and white (91.4%) with oropharyngeal cancer (55.8%). Males with myosteatosis had a physical QOL score 46.84 points lower at one-year following treatment completion (p = 0.01) than those with normal muscle density (p = 0.01). Males with myosteatosis averaged 57.57 points lower at one-year post-treatment (p = 0.01) in global QOL scores.
    CONCLUSIONS: Over one year following completion of treatment, patients with myosteatosis reported worse physical and global QOL scores than patients with normal muscle density.

    背景:本研究旨在评估局部开发的外固定器(LDEF)作为象牙海岸开放性胫骨骨干骨折(OTDF)的确定性治疗方法的有效性。
    方法:GustiloI,II,前瞻性纳入损伤后24小时内入院的患者和IIIAOTDF,并接受LDEF治疗。工会的比率,mal-union,败血症并发症,以及功能结果进行了评估,除了LDEF构造的完整性。评估了失败或不良结果的预测因素。
    结果:总体而言,40名OTDF患者在受伤后24小时内入院。GustiloI,II,和IIIA骨折观察到三个,13和24名患者,分别。29例骨折愈合不畅,平均工会时间为8.47个月。在三起和四起案件中登记了马勒工会和非工会,分别。13例发生针迹感染(PTI),7例发生深部感染。除四名患者外,所有患者的感染都得到了解决,得了慢性骨髓炎.没有一个非工会与感染有关。32例患者的总体功能结果令人满意。PTI是慢性感染的唯一预测因素。双平面框架,当与单平面结构相比时,与显著改善的功能结果相关。
    结论:LDEF显著改善了OTDF管理,因为它提供了更好的稳定性和优越的骨折愈合率比在相同的环境中观察到的标准护理。PTI仍然是一个基本问题,但是,希望,有限的负面后果。
    BACKGROUND: This study sought to evaluate the effectiveness of locally developed external fixators (LDEF) as definitive treatment for open tibia diaphyseal fractures (OTDF) in Ivory Coast.
    METHODS: Gustilo I, II, and IIIA OTDFs of patients admitted within 24 hours of injury were prospectively included and treated with LDEF. The rates of union, mal-union, septic complications, as well as the functional results were assessed, in addition to the LDEF construct\'s integrity. Predictive factors of failure or poor results were assessed.
    RESULTS: Overall, 40 OTDF patients were admitted within 24 hours of injury. Gustilo I, II, and IIIA fractures were observed in three, 13, and 24 patients, respectively. Uneventful fracture healing was obtained in 29 cases, with an average union time of 8.47 months. Mal-union and non-union were registered in three and four cases, respectively. Pin-track infection (PTI) was observed in 13 cases and deep infection in seven. Infection resolved in all patients except four, who developed chronic osteomyelitis. None of the non-unions were associated with an infection. The overall functional result was satisfactory in 32 patients. PTI was the only predictive factor for chronic infection. Biplanar frames, when compared to monoplanar constructs, were associated with a significantly improved functional outcome.
    CONCLUSIONS: LDEF improved significantly the OTDF management, as it provided better stability and superior fracture healing rates than what is observed with the standard of care in the same environment. PTI remains an essential problem but with, hopefully, limited negative consequences.

    目的:探讨西妥昔单抗联合放化疗治疗不可切除食管癌的疗效和毒性。
    方法:这项随机2期试验(clinicaltrials.gov,标识符NCT01787006)将放化疗加西妥昔单抗(A组)与放化疗(B组)用于不可切除的食管癌。主要目标是2年总生存期(OS)。如果2年OS≤40%(零假设=H0),则认为A组活动不足,如果95%置信区间的下限>45%,则有希望。如果下限>40%,H0被拒绝。次要目标包括无进展生存期(PFS),局部控制(LC),无转移生存率(MFS),回应,和毒性。该研究在74例患者后提前终止;68例患者可评估。
    结果:A组的两年OS为71%(95%CI:55-87%)与B组53%(95%CI:36-71%);H0被拒绝。中位OS为49.1vs.24.1个月(p=0.147)。死亡的危险比(HR)为0.60(95%CI:0.30-1.21)。在2年,PFS为56%vs.44%,LC84%与72%,和MFS74%与54%。进展的HR为0.51(0.25-1.04),局部失效为0.43(0.13-1.40),远处转移为0.43(0.17-1.05)。总体反应是81%vs.69%(p=0.262)。26名和27名患者,分别,经历至少一个毒性等级≥3(p=0.573)。发现≥3级过敏反应存在显着差异(12.5%与0%,p=0.044)。
    结论:鉴于本试验的局限性,放化疗加西妥昔单抗是可行的.有改善PFS和MFS的趋势。需要更大的研究来更好地定义西妥昔单抗在不可切除的食管癌中的作用。
    OBJECTIVE: To investigate the efficacy and toxicity of cetuximab when added to radiochemotherapy for unresectable esophageal cancer.
    METHODS: This randomized phase 2 trial (clinicaltrials.gov, identifier NCT01787006) compared radiochemotherapy plus cetuximab (arm A) to radiochemotherapy (arm B) for unresectable esophageal cancer. Primary objective was 2‑year overall survival (OS). Arm A was considered insufficiently active if 2‑year OS was ≤40% (null hypothesis = H0), and promising if the lower limit of the 95% confidence interval was >45%. If that lower limit was >40%, H0 was rejected. Secondary objectives included progression-free survival (PFS), locoregional control (LC), metastases-free survival (MFS), response, and toxicity. The study was terminated early after 74 patients; 68 patients were evaluable.
    RESULTS: Two-year OS was 71% in arm A (95% CI: 55-87%) vs. 53% in arm B (95% CI: 36-71%); H0 was rejected. Median OS was 49.1 vs. 24.1 months (p = 0.147). Hazard ratio (HR) for death was 0.60 (95% CI: 0.30-1.21). At 2 years, PFS was 56% vs. 44%, LC 84% vs. 72%, and MFS 74% vs. 54%. HRs were 0.51 (0.25-1.04) for progression, 0.43 (0.13-1.40) for locoregional failure, and 0.43 (0.17-1.05) for distant metastasis. Overall response was 81% vs. 69% (p = 0.262). Twenty-six and 27 patients, respectively, experienced at least one toxicity grade ≥3 (p = 0.573). A significant difference was found for grade ≥3 allergic reactions (12.5% vs. 0%, p = 0.044).
    CONCLUSIONS: Given the limitations of this trial, radiochemotherapy plus cetuximab was feasible. There was a trend towards improved PFS and MFS. Larger studies are required to better define the role of cetuximab for unresectable esophageal cancer.

    BACKGROUND: Definitive chemoradiotherapy (CRT) is the standard treatment for locally advanced head and neck cancer (HNC). However, for very elderly patients, the comparison of benefit/risk between definitive radiotherapy (RT) with and without systemic chemotherapy was equivocal.
    METHODS: The study was a single-institute, retrospective, cohort study. Seventy patients aged ≥75 years who had a locally advanced HNC were enrolled. The patients were divided into those with CRT and those with RT alone. Survival, compliance/adverse events and independent prognostic factors were analyzed.
    RESULTS: For baseline characteristics, the patients who received RT alone had worse performance status, comorbidity score and neutrophil-to-lymphocyte ratio. However, during definitive therapy, the CRT group had more adverse events such as neutropenia, febrile neutropenia and thrombocytopenia. There were no significant differences in disease-specific survival (DSS) and overall survival (OS) (P = 0.864 and 0.788, respectively). As to OS, several independent prognostic factors were identified. Performance status (hazard ratio [HR], 2.312; confidence interval [CI], 1.176-4.546; P = 0.015), clinical T staging (HR, 2.240; 95% CI, 1.021-4.913; P = 0.004) and total RT dose (HR, 2.555; 95% CI, 1.246-5.238; P = 0.010) were independent prognostic factors of OS.
    CONCLUSIONS: Definitive RT with or without systemic chemotherapy did not significantly influence DSS and OS for very elderly patients. Therefore, for elderly patients aged ≥ 75 years who have HNC, conservative RT might be sufficient for treatment purposes.
