Background: This article aimed to compile and summarize clinically relevant literature in radiation therapy, and to discuss the potential in radioresistant and radiosensitive head and neck cancer.

Study design: Narrative review.

Materials and methods: Google Scholar, PubMed and the Cochrane Library were retrieved using combined key words such as "radiotherapy" and "head and neck cancer". Search strings additionally queried were "radioresistant", "radiosensitive", "head and neck region", "squamous cell carcinoma", in combination with Boolean Operators 'AND' and 'OR'. Subsequently, the resulting publications were included for review of the full text.

Results: Radiotherapeutic response currently in clinical observation referred to HNSCC scoping were selected into this review. The compiled mechanisms were then detailed concerning on the clinical significance, biological characteristics, and molecular function.

Conclusions: Brachytherapy or/and external-beam radiotherapy are crucial for treating HNSCC, especially the early stage patients, but in patients with locally advanced tumors, their outcome with radiation therapy is poor due to obvious radioresistance. The curative effects mainly depend on the response of radiation therapy, so an updated review is needed to optimize further applications in HNSCC radiotherapy.

研究背景本文旨在梳理和总结放射治疗的临床相关文献,并探讨放射耐受性和放射敏感性头颈部癌症的治疗潜力:材料与方法使用 "放射治疗 "和 "头颈癌 "等组合关键词检索谷歌学术、PubMed 和 Cochrane 图书馆。此外,还查询了 "放射耐受性"、"放射敏感性"、"头颈部"、"鳞状细胞癌 "等搜索字符串,并结合布尔运算器 "AND "和 "OR"。随后,对检索到的文献进行全文检索:本综述选取了目前临床观察中涉及 HNSCC 范围的放射治疗反应。结论:近距离放疗或/和远距离放疗是目前最有效的治疗方法:结论:近距离放疗或/和体外放射治疗是治疗 HNSCC 的关键,尤其是早期患者,但对于局部晚期肿瘤患者,由于明显的放射抵抗,放疗效果不佳。治疗效果主要取决于放疗的反应,因此需要更新综述,以优化 HNSCC 放疗的进一步应用。

Background: Management of dual malignancies is challenging in the present scenario of advanced techniques and increased life expectancy. Objectives: To determine the demographic and clinical profile of patients with dual malignancies and the management received. Methods: In this retrospective analysis of the data of patients presenting with histologically proven synchronous or metachronous dual malignancy, we evaluated the demographic and clinical profile of patients with dual malignancies and the management received. Results: In this study, 158 cases with multiple primary cancers, of whom 57 were synchronous and 101 were metachronous, were observed from January 2017 to December 2021. The maximum period for synchronous tumor occurrence was seen at 6 months (180 days). The interval of occurrence of metachronous tumors ranged from 1 to 15 years, with an average of 4.8 years for the entire group. Moreover, 73 (46.2%) were females, and 85 (53.8%) were males, with a male-to-female ratio of 1.2: 1. The most common site of primary tumor with dual malignancies was the head and neck (31%), followed by breast cancers (21%). The most frequent pathologic type was adenocarcinoma (40%), followed by squamous carcinoma (38%), hematopoietic and lymphoid tissues (7.5%), transitional cell carcinoma (6.3%), sarcomas and soft tissue tumors (2.5%). Conclusions: Even in complete clinical remission, every cancer patient must take into account the possibility of developing a second malignancy and must be closely monitored.
背景:在目前先进技术和预期寿命增加的情况下,双重恶性肿瘤的管理是具有挑战性的。目的:确定双重恶性肿瘤患者的人口学和临床特征以及所接受的治疗。方法:回顾性分析组织学证实的同步或异时双重恶性肿瘤患者的资料,我们评估了双重恶性肿瘤患者的人口统计学和临床特征以及所接受的治疗。结果:本研究于2017年1月至2021年12月共观察到158例多发性原发癌,其中同步性57例,异时性101例。同时发生肿瘤的最长时间为6个月(180天)。异时性肿瘤发生的时间间隔为1 ~ 15年,全组平均为4.8年。其中女性73例(46.2%),男性85例(53.8%),男女比例为1.2:1。双恶性原发肿瘤最常见的部位是头颈部(31%),其次是乳腺癌(21%)。最常见的病理类型是腺癌(40%),其次是鳞状癌(38%)、造血和淋巴组织(7.5%)、移行细胞癌(6.3%)、肉瘤和软组织肿瘤(2.5%)。结论:即使在临床完全缓解,每个癌症患者都必须考虑到发生第二次恶性肿瘤的可能性,必须密切监测。

Background: The low incidence of myxofibrosarcoma (MFS) makes high power studies difficult to perform. Demographic and prognostic factors for MFS and how they differ from all extremity soft tissue sarcomas (STS) are not well understood. The purpose of this study was to characterize a large cohort of patients with MFS and evaluate epidemiologic and survival factors when compared to all STS. Material and methods: We performed a retrospective review of the Surveillance, Epidemiology, and End Results (SEER) database from 2000 to 2015 to identify 1,440 patients diagnosed with MFS and 12,324 with STS. Survival curves were creased using Kaplan-Meier, and Cox regression analyses were performed to identify hazard ratios (HRs). Results: Overall survival was greater for STS than MFS (79% vs. 67%). Patients with MFS had a higher average age at diagnosis than STS (62 vs. 56), and older age was strongly associated with decreased survivorship for MFS (HR = 7.94). A greater proportion of patients under 30 diagnosed with MFS were female when compared to STS (49.6% vs. 45.4%). The incidence of MFS and STS increased over the 15-year period, with MFS increasing at a greater rate than STS (1.25% vs. 2.59%). Survival increased for patients diagnosed after 2008 for both STS (9.4%) and MFS (13.2%). Conclusions: There are differences between patient demographics and survival factors when comparing MFS to all STS. Monitoring changes in demographic and survival trends for rare STS subtypes like MFS is important to improve diagnostic algorithms and treatment options.
背景:黏液纤维肉瘤(MFS)的低发病率使得高功率研究难以进行。MFS的人口统计学和预后因素以及它们与所有肢体软组织肉瘤(STS)的区别尚不清楚。本研究的目的是对一大批MFS患者进行特征分析,并与所有STS进行比较,评估流行病学和生存因素。材料和方法:我们对2000年至2015年的监测、流行病学和最终结果(SEER)数据库进行了回顾性分析,确定了1440例诊断为MFS的患者和12324例诊断为STS的患者。采用Kaplan-Meier法绘制生存曲线,并用Cox回归分析确定风险比(hr)。结果:STS的总生存率高于MFS (79% vs. 67%)。MFS患者诊断时的平均年龄高于STS(62比56),年龄越大与MFS的生存率降低密切相关(HR = 7.94)。与STS相比,30岁以下诊断为MFS的患者中女性的比例更高(49.6%对45.4%)。MFS和STS的发病率在15年期间呈上升趋势,其中MFS的发病率高于STS (1.25% vs. 2.59%)。2008年以后确诊的STS(9.4%)和MFS(13.2%)患者的生存率均有所提高。结论:与所有STS相比,MFS患者的人口学特征和生存因素存在差异。监测罕见STS亚型(如MFS)的人口统计学变化和生存趋势对于改进诊断算法和治疗方案非常重要。

Background: Several measurements defining the expected 30-day mortality (30-DM) to use in audit of radiation oncology departments have been proposed. However, its external validity is limited because of the lack of data from non-English speaking countries. This study assessed 30-DM in patients treated with palliative radiotherapy (PRT) in a Chilean-reference radiotherapy centre and explored if there had been tailored treatment at the end of life. Materials and methods: Retrospective data collection was carried out for all patients treated at our institution between 1st January 2018 and 31 st December 2021. Individual factors were modelled first to check for univariate association with 30-DM, those variables with a significance level of < 0.05 were considered for the final multivariable model. Results: 3,357 patients were included. The most common primary malignancies were breast (22%) and lung (16.1%). The most common treatment sites were bone (47.7%) and brain (12.2%). Overall, 30-DM was 14.7%, this rate was higher in patients treated for brain metastases (25.7%) and thoracic palliation (22.1%). 30-DM was associated with poor performance status (p < 0.01), lung and esophageal-gastric cancer (p = 0.04 and p = 0.02, respectively), metastases other than bone (p < 0.01), brain metastases (p < 0.01) and private health insurance (p <0.01). Conclusions: In patients treated for brain metastasis and thoracic palliation 30-DM was higher than suggested benchmarks. Moreover, in these groups long courses of PRT were often performed. Audit data should be useful for planning interventions that improve selection of patients and prompting review of policies for indication and fractionation schedules of PRT.
背景:已经提出了用于放射肿瘤科审计的几种确定预期30天死亡率(30-DM)的测量方法。然而,由于缺乏来自非英语国家的数据,其外部有效性受到限制。本研究评估了在智利参考放疗中心接受姑息性放疗(PRT)治疗的30-DM患者,并探讨是否在生命结束时进行了量身定制的治疗。材料和方法:回顾性收集2018年1月1日至2021年12月31日在我院治疗的所有患者的数据。首先对个体因素进行建模,以检查与30-DM的单变量关联,这些变量的显著性水平为<考虑0.05为最终的多变量模型。结果:共纳入3357例患者。最常见的原发恶性肿瘤是乳腺癌(22%)和肺癌(16.1%)。最常见的治疗部位为骨(47.7%)和脑(12.2%)。总体而言,30-DM为14.7%,这一比例在脑转移(25.7%)和胸部姑息治疗(22.1%)患者中更高。30-DM与不良运动状态相关(p <0.01),肺癌和食管胃癌(p = 0.04和p = 0.02),非骨转移(p <0.01),脑转移(p <0.01)和私人健康保险(p <0.01)。结论:在接受脑转移和胸部姑息治疗的患者中,30-DM高于建议的基准。此外,在这些组中,经常进行长疗程的PRT。审计数据应该有助于规划干预措施,以改善患者的选择,并促使审查PRT的指征和分级时间表政策。

Head and neck squamous cell carcinoma is one of the most common and fatal cancers worldwide. Lack of appropriate preventive screening tests, late detection, and high heterogeneity of these tumors are the main reasons for the unsatisfactory effects of therapy and, consequently, unfavorable outcomes for patients. An opportunity to improve the quality of diagnostics and treatment of this group of cancers are microRNAs (miRNAs) — molecules with a great potential both as biomarkers and therapeutic targets. This review aims to present the characteristics of these short non-coding RNAs (ncRNAs) and summarize the current reports on their use in oncology focused on medical strategies tailored to patients’ needs.
头颈部鳞状细胞癌是世界上最常见和最致命的癌症之一。缺乏适当的预防性筛查试验,发现晚,这些肿瘤的高度异质性是治疗效果不理想的主要原因,因此,对患者不利的结果。提高这类癌症的诊断和治疗质量的一个机会是microRNAs (miRNAs)——作为生物标志物和治疗靶点具有巨大潜力的分子。本文旨在介绍这些短链非编码rna (ncRNAs)的特征,并总结目前关于它们在肿瘤学中应用的报道,重点是针对患者需求的医疗策略。

Background: Early-stage high-risk breast cancer (BC) is standardly treated with breast-conserving therapy (BCT), combined with systemic therapy and radiotherapy (RT) ± tumor bed boost, e.g., with interstitial high-dose-rate brachytherapy (HDR-BT). To improve local recurrence rate (LRR), BT radiosensitization (thermal boost, TB) with interstitial microwave hyperthermia (MWHT) may be an option. The paper aims to report a retrospective single-institutional study on 5- and 10-year local control (LC), distant metastasis-free survival (DMFS), disease-free survival (DFS), overall survival (OS), cosmetic outcome (CO), and late toxicity (fibrosis, fat necrosis) after thermally enhanced HDR-BT boost to the BC tumor bed. Materials and methods: In 2006–2018, 557 early-stage (I–IIIA) high-risk BC patients were treated with BCT. If indicated, they were administered systemic therapy, then referred for 40.0–50.0 Gy whole breast irradiation (WBI) and 10 Gy interstitial HDR-BT boost (group A). Eligible patients had a single MWHT session preceding BT (group B). Based on present risk factors (RF), medium-risk (1–2 RF) and high-risk subgroups (≥ 3 RF) were formed. Patients were standardly checked, and control mammography (MMG) was performed yearly. Breast cosmesis (Harvard scale) and fibrosis were recorded. LC, DMFS, DFS, and OS were statistically analyzed. Results: Out of 557 patients aged 57 years (26-84), 364 (63.4%) had interstitial HDR-BT boost (group A), and 193 (34.6%) were preheated with MWHT (group B). Patients in group B had a higher clinical stage and had more RFs. The median follow-up was 65.9. Estimated 5-year and 10-year LC resulted in 98.5% and 97.5%, respectively. There was no difference in LC, DMFS, DFS, and OS between groups A and B and between extracted high-risk subgroups A and B. Five- and ten-year OS probability was 95.4% and 88.0%, respectively, with no difference between groups A and B. Harvard criteria-based CO assessment revealed good/excellent cosmesis in 74.9–79.1%. Tumor bed hardening was present in 40.1–42.2%. Asymptomatic fat necrosis-related macrocalcifications were detected in 15.6%, more frequently in group B (p = 0.016). Conclusions: Thermally boosted or not, HDR-BT was locally highly effective as part of combined treatment. Five- and ten-year LC, DMFS, DFS, and OS were high and equally distributed between the groups, although TB was prescribed in more advanced one with more RFs. TB did not influence CO and fibrosis. TB added to late toxicity regarding asymptomatic fat necrosis detected on MMG.
背景:早期高危乳腺癌(BC)的标准治疗是保乳治疗(BCT),结合全身治疗和放疗(RT)±肿瘤床强化治疗,例如间质性高剂量率近距离放疗(HDR-BT)。为了提高局部复发率(LRR), BT放射增敏(热增强,TB)与间质微波热疗(MWHT)可能是一种选择。本文旨在报道一项回顾性的单机构研究,对热增强HDR-BT促进BC肿瘤床后的5年和10年局部对照(LC)、远端无转移生存(DMFS)、无病生存(DFS)、总生存(OS)、美容结果(CO)和晚期毒性(纤维化、脂肪坏死)进行研究。材料与方法:2006-2018年,557例早期(I-IIIA)高危BC患者接受BCT治疗。如果有指征,则给予全身治疗,然后进行40.0-50.0 Gy全乳照射(WBI)和10 Gy间质HDR-BT增强(A组)。符合条件的患者在BT之前进行一次MWHT治疗(B组)。基于现有危险因素(RF),形成中危(1-2 RF)和高危亚组(≥3 RF)。对患者进行标准检查,并每年进行对照乳房x光检查(MMG)。记录乳房整形(哈佛评分)及纤维化情况。对LC、DMFS、DFS、OS进行统计学分析。结果:557例57岁(26-84岁)患者中,364例(63.4%)间质性HDR-BT增强(A组),193例(34.6%)MWHT预热(B组),B组患者临床分期较高,RFs较多。中位随访时间为65.9。估计5年和10年LC分别为98.5%和97.5%。LC、DMFS、DFS和OS在A组和B组之间以及抽取的高危亚组A和B之间没有差异。5年和10年的OS概率分别为95.4%和88.0%,A组和B组之间没有差异。基于哈佛标准的CO评估显示,74.9-79.1%的患者具有良好/优秀的美容效果。40.1-42.2%存在肿瘤床硬化。无症状脂肪坏死相关的大钙化发生率为15.6%,B组较高(p = 0.016)。结论:无论是否热增强,HDR-BT作为联合治疗的一部分,局部效果良好。5年和10年的LC、DMFS、DFS和OS在两组之间的分布都很高,尽管在更晚期的患者中开了结核病处方,但RFs更多。结核对CO和纤维化无影响。结核增加了MMG检测到的无症状脂肪坏死的晚期毒性。

To improve local recurrence rate (LRR), BT radiosensitization (thermal boost, TB) with interstitial microwave hyperthermia (MWHT) may be an option. The paper aims to report a retrospective single-institutional study on 5- and 10-year local control (LC), distant metastasis-free survival (DMFS), disease-free survival (DFS), overall survival (OS), cosmetic outcome (CO), and late toxicity (fibrosis, fat necrosis) after thermally enhanced HDR-BT boost to the BC tumor bed. Materials and methods: In 2006–2018, 557 early-stage (I–IIIA) high-risk BC patients were treated with BCT. If indicated, they were administered systemic therapy, then referred for 40.0–50.0 Gy whole breast irradiation (WBI) and 10 Gy interstitial HDR-BT boost (group A). Eligible patients had a single MWHT session preceding BT (group B). Based on present risk factors (RF), medium-risk (1–2 RF) and high-risk subgroups (≥ 3 RF) were formed. Patients were standardly checked, and control mammography (MMG) was performed yearly. Breast cosmesis (Harvard scale) and fibrosis were recorded. LC, DMFS, DFS, and OS were statistically analyzed. Results: Out of 557 patients aged 57 years (26-84), 364 (63.4%) had interstitial HDR-BT boost (group A), and 193 (34.6%) were preheated with MWHT (group B). Patients in group B had a higher clinical stage and had more RFs. The median follow-up was 65.9. Estimated 5-year and 10-year LC resulted in 98.5% and 97.5%, respectively. There was no difference in LC, DMFS, DFS, and OS between groups A and B and between extracted high-risk subgroups A and B. Five- and ten-year OS probability was 95.4% and 88.0%, respectively, with no difference between groups A and B. Harvard criteria-based CO assessment revealed good/excellent cosmesis in 74.9–79.1%. Tumor bed hardening was present in 40.1–42.2%. Asymptomatic fat necrosis-related macrocalcifications were detected in 15.6%, more frequently in group B (p = 0.016). Conclusions: Thermally boosted or not, HDR-BT was locally highly effective as part of combined treatment. Five- and ten-year LC, DMFS, DFS, and OS were high and equally distributed between the groups, although TB was prescribed in more advanced one with more RFs. TB did not influence CO and fibrosis.

Background: Patient navigation has been demonstrated to improve access to standard-of-care oncologic therapy. However, many patients — particularly those of African-American race — often do not have access to navigation upon receiving a diagnosis of cancer. As the most common cancer among African-American women is breast cancer, we sought to assess the rate of patient navigation among African-American breast cancer patients at our institution, which resides in a regional ZIP code comprised of 46% African-American residents. Materials and methods: African-American breast cancer patients who had been discussed at our weekly breast cancer multidisciplinary tumor board over a recent three-month period were assessed by a patient navigator representing the Navigator-Assisted Hypofractionation (NAVAH) program to determine their access to navigation in their cancer care. Responses were assessed from a breast cancer support group and culled to determine a baseline proportion of navigation utilization. Results : A total of 18 women of African-American race having been diagnosed with breast cancer were identified and assessed. Of these a total of 4 noted that they had received navigation, yielding a navigation utilization percentage of 22.2% among African-American breast cancer patients at our institution. Conclusion : The rate of navigation utilization among African-American breast cancer patients is poor. Despite our center residing in a region comprised of increased African-Americans, such predominance has not translated into optimizing navigation access for African-American breast cancer patients. This 22% rate of navigation utilization serves as a starting benchmark for initiatives such as the NAVAH program to provide tangible improvement in this patient population.
背景:患者导航已被证明可以改善获得标准护理肿瘤治疗的机会。然而,许多患者,尤其是非洲裔美国人,在被诊断为癌症时往往没有导航设备。由于非裔美国女性中最常见的癌症是乳腺癌,我们试图评估我们机构中非裔美国乳腺癌患者的患者导航率,该机构位于一个由46%的非裔美国居民组成的地区。材料和方法:在最近三个月的时间里,在我们的每周乳腺癌多学科肿瘤委员会上讨论的非裔美国乳腺癌患者由一名代表导航员辅助低分割(NAVAH)项目的患者导航员进行评估,以确定他们在癌症治疗中是否有导航。对来自乳腺癌支持小组的反馈进行评估,并进行筛选,以确定导航利用率的基线比例。结果:共有18名被诊断为乳腺癌的非裔美国女性被确定和评估。其中总共有4人指出他们接受了导航,在我们机构的非裔美国乳腺癌患者中,导航使用率为22.2%。结论:非裔美国人乳腺癌患者导航系统使用率较低。尽管我们的中心位于一个由越来越多的非裔美国人组成的地区,但这种优势并没有转化为优化非裔美国乳腺癌患者的导航通道。22%的导航利用率可以作为NAVAH计划等举措的起始基准,为这类患者群体提供切实的改善。

Background/Aim: The quality of treatment planning for stage III non-small cell lung cancer varies within and between facilities due to the different professions involved in planning. Dose estimation parameters were calculated using a feasibility dose-volume histogram (FDVH) implemented in the treatment planning quality assurance software PlanIQ. This study aimed to evaluate differences in treatment planning between occupations using manual FDVH-referenced treatment planning to identify their characteristics. Materials and methods: The study included ten patients with stage III non-small cell lung cancer, and volumetric-modulated arc therapy was used as the treatment planning technique. Fifteen planners, comprising five radiation oncologists, five medical physicists, and five radiological technologists, developed treatment strategies after referring to the FDVH. Results: Medical physicists had a higher mean dose at D98% of the planning target volume (PTV) and a lower mean dose at D2% of the PTV than those in other occupations. Medical physicists had the lowest irradiation lung volumes (V5 Gy and V13 Gy) compared to other professions, and radiation oncologists had the lowest V20 Gy and mean lung dose. Radiological technologists had the highest irradiation volumes for dose constraints at all indexes on the normal lung volume. Conclusions: The quality of the treatment plans developed in this study differed between occupations due to their background expertise, even when an FDVH was used as a reference. Therefore, discussing and sharing knowledge and treatment planning techniques among professionals is essential to determine the optimal treatment plan for each facility and patient.
背景/目的:III期非小细胞肺癌治疗计划的质量在机构内部和不同机构之间存在差异,因为计划涉及的专业不同。使用治疗计划质量保证软件PlanIQ中实现的可行性剂量-体积直方图(FDVH)计算剂量估计参数。本研究旨在评估不同职业在治疗计划方面的差异,采用手工fdvh参考治疗计划来确定其特征。材料与方法:本研究纳入10例III期非小细胞肺癌患者,采用体积调节电弧疗法作为治疗计划技术。15名计划人员,包括5名放射肿瘤学家、5名医学物理学家和5名放射技术专家,在参考FDVH后制定了治疗策略。结果:医学物理学家在计划靶体积(PTV) D98%处的平均剂量高于其他职业,在PTV D2%处的平均剂量低于其他职业。与其他职业相比,医学物理学家的肺辐照量(V5 Gy和V13 Gy)最低,放射肿瘤学家的V20 Gy和平均肺剂量最低。在正常肺容量的所有指标上,放射技师的剂量限制照射量最高。结论:本研究中制定的治疗计划的质量因职业的专业背景而异,即使使用FDVH作为参考。因此,在专业人员之间讨论和分享知识和治疗计划技术对于确定每个机构和患者的最佳治疗计划至关重要。

Background: In the treatment of vertebral bone metastases, estimating patient prognosis is important to select the optimal treatment strategy. The purpose of this study was to identify prognostic factors for vertebral bone metastases treated with palliative radiotherapy and to establish a nomogram for predicting patient survival. Materials and methods: We analyzed patients who underwent palliative radiotherapy for vertebral bone metastasis between January 2010 and December 2020 at a single institution. Exclusion criteria were as follows: (1) primary bone malignancy, (2) stereotactic body radiotherapy, (3) concurrent radiotherapy to sites other than the vertebral bone, (4) radiotherapy to other sites within 12 weeks before or after the current radiotherapy, and (5) lack of more than half of blood test data before radiotherapy. Results: A total of 487 patients met the inclusion criteria. Clinical and hematologic data were collected from the patient record system. Patients were divided into training and test groups in a 7:3 ratio. Multivariate Cox regression analysis in the training cohort revealed six significant factors, including a history of chemotherapy, primary site (breast cancer, prostate cancer, or hematologic malignancy), use of analgesics, neutrophil-lymphocyte ratio, serum albumin, and lactate dehydrogenase. A prognostic nomogram was developed and validated in the test cohort. The area under the curve (AUC) values in predicting survival at 6, 24, and 60 months were 0.83, 0.88, and 0.88 in the training cohort and 0.85, 0.81, and 0.79 in the test cohort, respectively. Conclusions: This nomogram may help to select the treatment strategy for vertebral bone metastases.
背景:在椎体骨转移瘤的治疗中,评估患者预后对选择最佳治疗策略至关重要。本研究的目的是确定经姑息性放疗治疗的椎体骨转移的预后因素,并建立预测患者生存的nomogram。材料和方法:我们分析了2010年1月至2020年12月在单一机构接受脊椎骨转移姑息放疗的患者。排除标准如下:(1)原发性骨恶性肿瘤;(2)立体定向体放疗;(3)椎体以外部位同步放疗;(4)本次放疗前后12周内其他部位放疗;(5)放疗前血液检查资料缺失一半以上。结果:共有487例患者符合纳入标准。临床和血液学数据从患者记录系统中收集。患者按7:3的比例分为训练组和试验组。培训队列的多变量Cox回归分析显示了六个显著因素,包括化疗史、原发部位(乳腺癌、前列腺癌或血液系统恶性肿瘤)、镇痛药的使用、中性粒细胞-淋巴细胞比率、血清白蛋白和乳酸脱氢酶。在测试队列中开发并验证了预后nomogram。预测6个月、24个月和60个月生存率的曲线下面积(AUC)值在训练组中分别为0.83、0.88和0.88,在测试组中分别为0.85、0.81和0.79。结论:该图可能有助于选择椎体骨转移的治疗策略。

Background: The purpose was to evaluate the incidence of acute and late rectal toxicities and their correlation with the clinical and dosimetric parameters of patients who underwent curative radiotherapy for localized prostate cancer at the Akanda Cancer Institute, Gabon. Materials and methods: Between 2013 and 2021, a cohort of 46 patients with clinically localized stage cT1c-T4 prostate cancer was treated with three-dimensional conformal radiation therapy (3D-CRT) at the national cancer institute with doses ranging from 66 to 80 Gy. Post-radiation gastrointestinal (GI) toxicities were classified and graded according to the Common Terminology Criteria for Adverse Events (CTCAE) v4.0. Results: In our study, 17.4% (8/46) developed acute GI. Grades 1 and 3 acute GI complications were seen in 13.0% (6/46) and 4.3% (2/46), respectively. No patient developed acute grade 2 or grade higher than 3 complications. Late GI side effects were limited. The median time to the development of late GI Grade ≥ 1 toxicities was 12 months (range: 9-19 months). 10.9% (5/46) had experience late GI. Among them, grade 1 and 2 were seen in 6.5% (3/46), and 4.3% (2/46), respectively. There was no grade 3 or higher complications. Statistically, we did not find any correlation between the presence of rectal toxicity and clinical factors or the presence of comorbidity. On the dosimetric level, the Mann-Whitney statistical test found a correlation between the presence of late GI toxicity and rectal volume irradiated at the prescribed dose (p = 0.02). Conclusion: Despite the high radiation doses involved, our results showed an acceptable complication rate.
背景:目的是评估急性和晚期直肠毒性的发生率,以及它们与加蓬Akanda癌症研究所接受治疗性放疗的局限性前列腺癌患者的临床和剂量参数的相关性。材料和方法:2013年至2021年,在美国国家癌症研究所,46例临床定位期cT1c-T4前列腺癌患者接受了三维适形放射治疗(3D-CRT),剂量范围为66至80 Gy。根据不良事件通用术语标准(CTCAE) v4.0对放射后胃肠道(GI)毒性进行分类和分级。结果:在本研究中,17.4%(8/46)的患者发生急性GI。1级和3级急性胃肠道并发症发生率分别为13.0%(6/46)和4.3%(2/46)。没有患者出现急性2级或3级以上的并发症。晚期胃肠道副作用有限。发生晚期GI≥1级毒性的中位时间为12个月(范围:9-19个月)。10.9%(5/46)有过GI晚期经历。其中,1级和2级分别占6.5%(3/46)和4.3%(2/46)。无3级及以上并发症。统计上,我们没有发现直肠毒性的存在与临床因素或合并症的存在有任何相关性。在剂量学水平上,Mann-Whitney统计检验发现,在规定剂量照射下,晚期胃肠道毒性的存在与直肠体积之间存在相关性(p = 0.02)。结论:尽管辐射剂量很大,但我们的结果显示并发症发生率是可以接受的。
