Clinical Outcomes and Prognostic Factors of Salvage Stereotactic Body Radiotherapy for Post-Surgical Thoracic Oligo-Recurrence/Metastasis of Non-Small-Cell Lung Cancer.

PurposeThe study aimed to assess the efficacy and safety of stereotactic body radiotherapy (SBRT) using CyberKnife (CK) in patients with postoperative thoracic oligo-recurrence/metastasis of non-small-cell lung cancer (NLCLC), and to analyze the prognostic factors affecting overall survival after SBRT.Patients and MethodsA total of 44 patients with postoperative thoracic oligo-recurrence/metastatic of NLCLC treated with SBRT were reviewed. Thoracic oligo-recurrence/was defined as 1–3 loco-regional confined to lung lobe, hilar/mediastinal lymph nodes, bronchial stump, or chest wall. Primary endpoints included local control (LC), overall survival (OS), progression-free survival (PFS) and toxicity. Prognostic factors that affected these patients were analyzed by the univariate and multivariate analysis by Kaplan–Meier methods and Cox regression models, respectively.ResultsThe median follow-up time after salvage SBRT was 48.5 months. Measuring from the date of salvage SBRT, the median OS of the 44 patients was 52.60 (95% CI: 29.59–75.60) months. 1-,3-and 5-year OS rates were 97.7%, 65.3% and 47.7%, respectively. The 1-,3-year and 5-year LC rates were 97.7%, 85.1% and 80.1%, respectively. At 1, 3 and 5 years, the PFS rates were 77.1%, 28.8% and 5.3%, respectively. Multivariate analysis demonstrated that pre-SBRT neutrophil-to-lymphocyte ratio (NLR) and Charlson comorbidity index (CCI) were independent prognostic factors (p < 0.05). The treatment-related side-effects were well tolerated. No patients developed grade 3 or greater pulmonary toxicity.ConclusionSBRT is a promising salvage therapeutic option for postoperative thoracic oligo-recurrence/metastasis of non-small-cell lung cancer with acceptable toxicity. Low pre-SBRT neutrophil-to-lymphocyte ratio (NLR) and low Charlson comorbidity index (CCI) were associated with a better prognosis and longer survival and might be considered as reliable and independent prognostic factors in these patients treated with SBRT.

Proton Beam Therapy for Children With Neuroblastoma: Experiences From the Prospective KiProReg Registry.

ObjectiveRadiotherapy (RT) is an integral part of the interdisciplinary treatment of patients with high-risk neuroblastoma (NB). With the continuous improvements of outcome, the interest in local treatment strategies that reduce treatment-related side effects while achieving optimal oncological results is growing. Proton beam therapy (PBT) represents a promising alternative to conventional photon irradiation with regard to the reduction of treatment burden.MethodRetrospective analysis of children with high or intermediate risk NB receiving PBT of the primary tumor site during first-line therapy between 2015 and 2020 was performed. Data from the prospective in-house registry Standard Protonentherapie WPE – Kinder- (KiProReg) with respect to tumor control and treatment toxicity were analyzed. Adverse events were classified according to CTCAE Version 4 (V4.0) before, during, and after PBT.ResultsIn total, 44 patients (24 male, 20 female) with high (n = 39) or intermediate risk NB (n = 5) were included in the analysis. Median age was 3.4 years (range, 1.4–9.9 years). PBT doses ranged from 21.0 to 39.6 Gray (Gy) (median 36.0 Gy). Five patients received PBT to the MIBG-avid residual at the primary tumor site at time of PBT according to the NB-2004 protocol. In 39 patients radiation was given to the pre-operative tumor bed with or without an additional boost in case of residual tumor. After a median follow-up (FU) of 27.6 months, eight patients developed progression, either local recurrence (n = 1) or distant metastases (n = 7). Four patients died due to tumor progression. At three years, the estimated local control, distant metastatic free survival, progression free survival, and overall survival was 97.7, 84.1, 81.8, and 90.9%, respectively. During radiation, seven patients experienced higher-grade (CTCAE ≥ °3) hematologic toxicity. No other higher grade acute toxicity occurred. After PBT, one patient developed transient myelitis while receiving immunotherapy. No higher grade long-term toxicity was observed up to date.ConclusionPBT was a well tolerated and effective local treatment in children with high and intermediate risk NB. The role of RT in an intensive multidisciplinary treatment regimen remains to be studied in the future in order to better define timing, doses, target volumes, and general need for RT in a particularly sensitive cohort of patients.

A qualitative study of adolescent cancer survivors perspectives on social support from healthy peers – A RESPECT study

Adolescents' psychosocial development is generally influenced by their peers. Those facing hospital-based cancer treatment are particularly challenged as they are isolated from their social network and lack sufficient coping resources. This study explores the adolescent cancer survivor's perceptions and experiences with healthy classmate socialization support efforts via hospital co-admittance, from diagnosis to reinstatement in school, as an intervention of the RESPECT (REhabilitation including Social and Physical Activity and Education in Children and Teenagers with cancer) Study. A phenomenological, descriptive study. Using variation sampling, 14 adolescents (aged 14-19), who completed the RESPECT intervention (April 2016-July 2017), participated in qualitative, in-depth, semi-structured interviews that were thematically analysed. Four themes emerged: (a) Ambassadors as liaison persons; (b) Ambassadors as promoters of normalization and identity continuity; (c) Ambassadors as 'behind the scenes' friends; and (d) feelings of vulnerability and inferiority. Ambassadors reinstated a sense of normalcy in the adolescents' daily life. They supported identity construction and served as liaison persons who buffered loneliness and social isolation as well as bridging a continued sense of belonging to one's school peer network. In contrast with other peers, ambassadors understood cancer-related issues, knowledge which they partially gained witnessing the impact of treatment-related side effects on their hospitalized classmates. However, the consequence of this trade-off was an asymmetry in their relationship, with the adolescents requiring a certain level of safeguard from their ambassadors to maintain equal power in the relationship. The ambassadors enhanced the adolescents' ability to cope with their altered social position during treatment and to psychosocially reinstate it on their return to school. Future interventions should offer opportunities for healthy peers to be educated in what it means to live with cancer. Future programs to sustain socialization in adolescents with cancer should involve healthy peers for the entirety of the treatment period.

An Experience on Pomalidomide in Patients within Relapsed/Refractory Multiple Myeloma - A Multicenter Study in Turkey

Objective: Pomalidomide is a new generation thalidomide analogue. Effectiveness as a single agent or combination with low dose dexamethasone has been in the treatment of relapse/refractory Multiple Myeloma (MM). The aim of the present study was to share the experience of different oncology centres with pomalidomide treatment in patients with relapsed/refractory MM.&#x0D; Materials and Methods: Seventy-three patients from 16 centres were enrolled into the study. The patients were followed for a median of 6 months. Relapsed/refractory MM patients who received at least one line of treatment before pomalidomide were included into the study. ISS, R-ISS and Eastern Cooperative Oncology Group (ECOG) scores of the patients and treatment-related side effects were evaluated.&#x0D; Results: As a result of the median follow-up for 6 months, 36% (26/72) of the patients presented progression. The estimated median PFS was found 29 months. The Cox regression analysis revealed that ECOG affected PFS only, myeloma subtype; ISS and R-ISS scores did not affect PFS. The most common side effects with pomalidomide treatment in our population include neutropenia, infections, anaemia and thrombocytopenia.&#x0D; Conclusion: In our study, it was statistically shown that the ECOG score was effective in survival in relapsed / refractory MM patients treated by pomalidomide. Therefore, we recommend evaluation of the ECOG score for each patient before treatment in eligible cases.

Should Grade Group 1 (GG1) be called cancer?

ISUP Grade Group 1 prostate cancer is the lowest histologic grade of prostate cancer with a clinically indolent course. Removal of the term 'cancer' has been proposed and has historical precedent both in urothelial and thyroid carcinoma. Evidence-based review identifying arguments for and against Grade Group 1 being referred to as cancer. Grade Group 1 has histologic evidence of tissue microinvasion and 0.3-3% rate of extraprostatic extension. Genomic evaluation suggests overlap of a minority of Grade Group 1 cancers with those of Grade Group 2. Conversely, Grade Group 1 tumors appear to have distinct genetic and genomic profiles from Grade Group 3 or higher tumors. Grade Group 1 has no documented ability for regional or distant metastasis and long-term follow up after treatment or active surveillance is safe with excellent oncologic outcomes. Grade Group 1 prostate cancer, while showing evidence of neoplasia on histology has a remarkably indolent natural history more akin to non-neoplastic precursor lesions. Consideration should be given to renaming Grade Group 1 prostate cancer, which has the potential to minimize overtreatment, treatment-related side effects, patient anxiety, and financial burden on the healthcare system.

Supportive Care Needs of Patients on Surveillance and Treatment for Non-Muscle-Invasive Bladder Cancer.

This literature review provides an overview of non-muscle-invasive bladder cancer diagnosis (NMIBC), treatment, and surveillance. Existing evidence is reviewed to identify the NMIBC patient pathway, highlight its effect on quality of life, and identify supportive care needs of this patient group. A framework to guide nurses in the care of this underserved population is proposed. Electronic databases including CINAHL, Medline, PsychInfo, Cochrane, and Google Scholar were searched. NMIBC is a chronic disease with high recurrence and progression rates with most patients requiring invasive treatment and burdensome surveillance schedules with frequent hospital visits. Treatment-related side effects may interrupt therapy and possibly result in its discontinuation. Patients' quality of life can be negatively affected at various stages of the cancer trajectory. Specialist nurses provide holistic care throughout all stages of the patient journey to optimize supportive care, information provision, and delivery of appropriate treatment and surveillance protocols. NMIBC research is historically underfunded with a paucity of evidence identifying the supportive care needs of this population. Further research is urgently required to fill the gaps identified. This timely paper raises the profile of unmet supportive care needs in an underserved research cancer population. Suggestions are proposed to improve the quality of nursing care through standardized practices and the development and integration of patient pathways. Evidence of the effect of NMIBC on family members or carers is absent from the literature. Future research implications and directions are proposed.

Update on management of pediatric atopic dermatitis

Atopic dermatitis is the most common chronic inflammatory skin disease in children. It usually develops in infancy and early child hood and is an entry point of ‘atopic march’, which may progress to other allergic diseases, including allergic rhinitis and asthma. Al though there is no disagreement on the importance of early treatment of atopic dermatitis, it is difficult to treat children with mod erate to severe atopic dermatitis due to concerns about treatment-related side effects and age restrictions for effective drugs in real world. As recent researches have extend our understanding of pathogenesis, new agents targeted key pathologic mechanisms have been developed. Therefore, it is time to establish a new paradigm of treatment for children with atopic dermatitis since new biologics have been demonstrated to be effective and safe in children. The objective of this article is to review the clinical character istics, severity classification, pathogenesis, and treatment, in particular, biologics already approved/undergoing clinical trials for chil dren with atopic dermatitis.

Impact of interfractional target motion in locally advanced cervical cancer patients treated with spot scanning proton therapy using an internal target volume strategy.

Background and purposeThe more localized dose deposition of proton therapy (PT) compared to photon therapy might allow a reduction in treatment-related side effects but induces additional challenges to address. The aim of this study was to evaluate the impact of interfractional motion on the target and organs at risk (OARs) in cervical cancer patients treated with spot scanning PT using an internal target volume (ITV) strategy.Methods and materialsFor ten locally advanced cervical cancer patients, empty and full bladder planning computed tomography (pCT) as well as 25 daily cone beam CTs (CBCTs) were available. The Clinical Target Volume (CTV), the High Risk CTV (CTVHR) (gross tumor volume and whole cervix), the non-involved uterus as well as the OARs (bowel, bladder and rectum) were contoured on the daily CBCTs and transferred to the pCT through rigid bony match. Using synthetic CTs derived from pCTs, four-beam spot scanning PT plans were generated to target the patient-specific ITV with 45 Gy(RBE) in 25 fractions. This structure was defined based on pre-treatment MRI and CT to anticipate potential target motion throughout the treatment. D98% of the targets and V40Gy(RBE) of the OARs were extracted from the daily anatomies, accumulated and analyzed. In addition, the impact of bladder volume deviations from planning values on target and bowel dose was investigated.ResultsThe ITV strategy ensured a total accumulated dose >42.75 Gy(RBE) to the CTVHR for all ten patients. Two patients with large bladder-related uterus motion had accumulated dose to the non-involved uterus of 35.7 Gy(RBE) and 41.1 Gy(RBE). Variations in bowel V40Gy(RBE) were found to be correlated (Pearson r = −0.55; p-value <0.0001) with changes in bladder volume during treatment.ConclusionThe ITV concept ensured adequate dose to the CTVHR, but was insufficient for the non-involved uterus of patients subject to large target interfractional motion. CBCT monitoring and occasional replanning is recommended along the same lines as with photon radiotherapy in cervical cancer.

Associations of Physical Activity and Exercise with Health-related Outcomes in Patients with Melanoma During and After Treatment: A Systematic Review.

Purpose:Although exercise medicine is recommended to counter treatment-related side-effects and improve health-related outcomes of patients affected by different cancers, no specific recommendations exist for patients with melanoma. As a result, we systematically examined the current evidence regarding the effects of physical activity and exercise on objectively-measured and patient-reported outcomes among patients with melanoma.Methods:Searches were conducted in PubMed, CINAHL, EMBASE, SPORTDiscus, and Web of Science databases. This review included published data involving physical activity or exercise and objectively-measured or patient-reported outcomes of patients with cutaneous melanoma. The quality of included studies was assessed using the McMaster University Critical Appraisal Tool for Quantitative Studies.Results:Six studies including 882 patients with melanoma were included. Studies presented heterogeneity of design with 2 cross-sectional surveys, 2 retrospective analyses, and 2 non-randomized intervention trials. No statistically significant change in quality of life, fatigue, physical function, cardiorespiratory fitness, body composition, psychological distress, cognitive function, or treatment-related side-effects were attributable to physical activity or exercise. Importantly, physical activity or exercise during melanoma treatment or into survivorship did not adversely impact patients/survivors.Conclusion:In summary, physical activity or exercise did not adversely impact quality of life, objectively-measured or patient-reported outcomes in patients with melanoma. In addition, there is a paucity of quality studies examining the effects of physical activity or exercise on patients with melanoma throughout the cancer care continuum.

Surgical Interventions for COPD.

Chronic obstructive pulmonary disease (COPD) treatment is aimed at managing the disease rather than cure, with a focus on improving quality of life and decreasing exacerbations. Interventional therapies, including lung volume reduction surgery, bullectomy, lung transplantation, and bronchoscopic lung volume reduction treatment using endobronchial valves, are treatment options for patients with COPD who are symptomatic due to hyperinflation despite optimal medical management. We will review the current literature to provide a comprehensive summary of the currently available scientific data, discuss typical treatment-related side effects, and evidence-based management approach and recommendations for patient selection in clinical practice.

The Use of Prebiotic and Probiotic Interventions for Treating Gastrointestinal and Psychosocial Health Symptoms in Cancer Patients and Survivors: A Systematic Review.

Background:Cancer treatments can cause significant gastrointestinal (GI) health issues, and negatively affect patient’s psychosocial health and quality of life (QOL). Novel, integrative strategies using prebiotics and probiotics have been explored for treating adverse cancer treatment-related side effects. We evaluated the current literature for interventions using prebiotics or probiotics specifically to treat GI and psychosocial health issues in cancer patients and survivors.Methods:Five databases (PubMed, MEDLINE (Ovid), CINHAL, PsychINFO, Web of Science) were searched for studies with prebiotic or probiotic interventions where GI and/or psychosocial health outcomes were measured in adult cancer patients and survivors, and published before September 12th 2021.Results:Twelve studies (N = 974 participants) meeting the inclusion criteria were identified (randomized controlled trials [n = 10], single-group pre-post studies [n = 2]). Ten studies were conducted with patients on active cancer treatment, and 2 studies treated patients after anti-cancer therapies. Three studies used prebiotics, 7 studies used probiotics, and 2 studies used a combination therapy. The most commonly used probiotic strains were from the Lactobacillus genus. There was minimal evidence for prebiotics to improve GI or psychosocial health. Probiotics were associated with significant improvements in abdominal pain (n = 2), gas/bloating (n = 2), and especially diarrhea (n = 5), and with improvements in anxiety (n = 1), depression (n = 1), fatigue (n = 1), and QOL (n = 2).Conclusions:Studies specifically examining effects of prebiotics and probiotics on GI and psychosocial health outcomes are scarce. Probiotic intervention may improve some GI symptoms in cancer patients, and QOL in survivors. Controlled trials that consistently include GI and psychosocial health outcomes are needed.

Model-based prediction of oncotherapy risks and side effects in bladder cancer

Abstract The prediction of cancer treatment side-effects requires the capturing of complex biophysical therapy parameters and the integration of different medical knowledge elements. In relation with radiotherapy, it is widely observed that the uncontrolled processes or undefined radiation therapy dose can decline the state of treatment. Precisely, the inability to manage the flow of available information, usually provided in heterogeneous formats, made it complicated to oversee and predict risks and effects of a prescribed treatment protocol. We think that, the optimization of knowledge representation and modelling in the context of evidence-based medicine can support the automated prediction of risks and side effects in oncotherapy. The following manuscript describes our methodology used for the design of a bladder cancer treatment side effects ontology embedded with evidence-based semantic rules and queries. Treatment knowledge is represented along with a particular consideration to the modelling of its referred risks and side effects. Our ontology model helps in improving the streamlining of medical practices and clinical decision-making. Within our semantic web approach, better strategies are applied for treatment selection with reference to possible side effects. Our ontology depicts real world scenario of developing treatment-related side effects. Furthermore, it is a clinical decision support system founding tool that highlights treatments efficiency. Our model shares treatment knowledge, facts and effects. Moreover, it includes medical evidence and incorporates a semantic rule base for systemic prediction results.

The Therapeutic Effects of Acupuncture and Electroacupuncture on Cancer-related Symptoms and Side-Effects.

In addition to cancer-related death, malignant progression also leads to a series of symptoms and side-effects, which would detrimentally affect cancer patients' the quality of life, adversely influence their adherence to treatments, and, therefore, negatively affect their long-term survival. Acupuncture and electroacupuncture (EA), as two classic treatment methods in traditional Chinese medicine, have been widely employed to cure various diseases. Recently, the clinical application of acupuncture and EA in cancer patients has received great attention. In this review, we summarized the clinical application of acupuncture and EA in alleviating the cancer symptoms, reducing the cancer treatment-related side-effects, and relieving the cancer pain. The symptoms and side-effects discussed in this review include fatigue, insomnia, chemotherapy-associated dyspepsia syndrome (CADS), pain, xerostomia, and anxiety and depression. The underlying mechanisms of the therapeutic effects of acupuncture and EA might be related to the regulation of the mitochondrial function, coordination of the activity of the nervous system, adjustment of the production of neurotransmitters, and alleviation of the immune responses. In conclusion, acupuncture and EA have been proved to be beneficial for cancer patients. More research, however, is required to clarify the potential mechanisms behind acupuncture and EA for widespread adoption in clinical application.

5-Year outcomes of the prospective and randomized CISTCERT study comparing steroid withdrawal to replacement of cyclosporine with everolimus in de novo kidney transplant patients.

Withdrawal of either steroids or calcineurin inhibitors are two strategies to reduce treatment-related side effects and improve long-term outcomes of kidney transplantation. The CISTCERT study compared the efficacy and safety of these two strategies. In this multicenter, randomized controlled trial, 151 incident kidney transplant recipients received cyclosporine (CsA), mycophenolic acid (MPA), and steroids during three months, followed by either steroid withdrawal (CsA/MPA) or replacement of cyclosporine with everolimus (EVL) (EVL/MPA/steroids). 5-year patient survival (89% vs. 86%; P=NS) and death-censored graft survival (95% vs. 96%; P=NS) were comparable in the CsA/MPA and EVL/MPA/steroids arm, respectively. 51 CrEDTA clearance was comparable in the intention-to-treat analysis, but in the on-treatment population, the EVL/MPA/steroids arm exhibited a superior 51 CrEDTA clearance at 1 and 5years after transplantation (61.6 vs. 52.4, P=0.05 and 59.1 vs. 46.2ml/min/1.73m2 , P=0.042). Numerically more and more severe rejections were observed in the EVL/MPA/steroids arm, which also experienced a higher incidence of posttransplant diabetes (26% vs. 6%, P=0.0016) and infections. No significant differences were observed in cardiovascular outcomes and malignancy. Both regimens provide an excellent long-term patient survival and graft survival. Regarding graft function, EVL/MPA/steroids is an attractive strategy for patients with good tolerability who remain free of rejection.

BRAF paradox breakers PLX8394, PLX7904 are more effective against BRAFV600Ε CRC cells compared with the BRAF inhibitor PLX4720 and shown by detailed pathway analysis

PLX7904 and PLX8394 are novel BRAFV600E inhibitors-BRAFi that are designed to evade the paradoxical MAPK activation, a trait for the name “paradox breakers”-PB. Current FDA approved inhibitors (Vemurafenib, Dabrafenib, Encorafenib) although improved progression-free survival of mtBRAF melanoma patients suffer from this treatment related side effect. mtBRAF Colorectal Cancer (CRC) is resistant to the approved BRAF inhibitors, although combinatorial treatment co-targeting BRAF and EGFR/MEK is offering a promising prospect. In an effort to explore the potential of the novel BRAF inhibitors-PB to impede CRC cell proliferation, they were tested on RKO, HT29 and Colo-205 cells, bearing the BRAFV600E mutation. This study shows that the BRAF paradox breakers PLX7904 and PLX8394 cause a more prolonged MAPK pathway inhibition and achieve a stronger blockage of proliferation and reduced viability than PLX4720, the sister compound of Vemurafenib. In some treatment conditions, cells can undergo apoptosis. Genomic analysis on the more resistant RKO cells treated with PLX7904, PLX8394 and PLX4720 showed similar gene expression pattern, but the alterations imposed by the PB were more intense. Bioinformatic analysis resulted in a short list of genes representing potential master regulators of the cellular response to BRAF inhibitors' treatments. From our results, it is clear that the BRAF paradox breakers present a notable differential regulation of major pathways, like MAPK signalling, apoptosis, cell cycle, or developmental signalling pathways. Combinatorial treatments of BRAFi with Mcl-1 and Notch modulators show a better effect than mono-treatments. Additional pathways could be further exploited in novel efficient combinatorial treatment protocols with BRAFi.

Suppression of Metastatic Melanoma Growth in Lung by Modulated Electro-Hyperthermia Monitored by a Minimally Invasive Heat Stress Testing Approach in Mice.

Simple SummaryThe lung is the most frequent site of distant melanoma metastases. Metastases of melanoma in the lungs offer a very poor prognosis, with a 5-year survival rate of below 10%. Hyperthermic therapies including modulated electro-hyperthermia (mEHT) in clinical settings have been used to improve the efficacy of radiotherapy, chemotherapy, and immunotherapy of tumors. In this study, we focused primarily on the optimization of mEHT for targeted lung treatment of mice lungs burdened with B16F10 melanoma pulmonary metastases, with a particular focus on elucidating the mechanism of action of mEHT on treated melanoma cells while investigating any potential treatment-related side effects on normal lung tissue. mEHT showed evidence of significant anti-tumor effects as demonstrated by the reduced number of pulmonary metastatic nodules, DNA damage response, downregulation of Ki67 expression, higher immune cell infiltration, and upregulation of p21waf1 expression in mEHT-treated tumors.Modulated electro-hyperthermia (mEHT) is a novel complementary therapy in oncology which is based on the higher conductivity and permittivity of cancerous tissues due to their enhanced glycolytic activity and ionic content compared to healthy normal tissues. We aimed to evaluate the potential of mEHT, inducing local hyperthermia, in the treatment of pulmonary metastatic melanoma. Our primary objective was the optimization of mEHT for targeted lung treatment as well as to identify the mechanism of its potential anti-tumor effect in the B16F10 mouse melanoma pulmonary metastases model while investigating the potential treatment-related side effects of mEHT on normal lung tissue. Repeated treatment of tumor-bearing lungs with mEHT induced significant anti-tumor effects as demonstrated by the lower number of tumor nodules and the downregulation of Ki67 expression in treated tumor cells. mEHT treatment provoked significant DNA double-strand breaks indicated by the increased expression of phosphorylated H2AX protein in treated tumors, although treatment-induced elevation of cleaved/activated caspase-3 expression was insignificant, suggesting the minimal role of apoptosis in this process. The mEHT-related significant increase in p21waf1 positive tumor cells suggested that p21waf1-mediated cell cycle arrest plays an important role in the anti-tumor effect of mEHT on melanoma metastases. Significantly increased CD3+, CD8+ T-lymphocytes, and F4/80+CD11b+ macrophage density in the whole lung and tumor of treated animals emphasizes the mobilizing capability of mEHT on immune cells. In conclusion, mEHT can reduce the growth potential of melanoma, thus offering itself as a complementary therapeutic option to chemo- and/or radiotherapy.

Topical capsaicin versus topical ibuprofen in acute musculoskeletal injuries: A randomized, double-blind trial

Background: Acute musculoskeletal pain is one of the common causes of emergency admissions. Topical analgesics are an easily tolerated option in the treatment of these pains. Objective: This study aimed to compare the efficacy of topical capsaicin and topical non-steroidal anti-inflammatory drugs in acute musculoskeletal injuries. Methods: In this prospective, randomized, controlled, double-blinded study, patients were allocated to two groups—the topical non-steroidal anti-inflammatory drug (n = 60) and topical capsaicin (n = 59). For both groups, the first dose treatment was applied as a thin layer in the emergency department to a maximum area of 5 × 5 cm. The remaining doses were administered at home by the patients for 72 h. The initial visual analog scale scores were compared with the 60th and 120th minute as well as the 24th and 72nd hour values. Differences between the visual analog scale scores, clinical response to the treatment, and side effects were evaluated. Results: The proportional reduction in visual analog scale scores for topical capsaicin was significantly higher, especially at 36 and 72 h. These rates were 0.75 (95% confidence interval: 0.77–1.42; p = 0.029) and 9.08 (95% confidence interval: 1.02–17.14; p = 0.028) at 36 h, respectively. At 72 h, they were 1.27 (95% confidence interval: 0.48–2.05; p = 0.002) and 17.07 (95% confidence interval: 8.39–25.76; p &lt; 0.001), respectively. In the topical capsaicin group, the clinical response to treatment was significantly higher (p = 0.001). Treatment-related systemic side effects were experienced only in the topical non-steroidal anti-inflammatory drug group (1.7%). Conclusion: Topical capsaicin can be used safely in patients presenting to the emergency department with acute pain with its high analgesic efficacy and absence of systemic side effects.

Identifying Actionable Causes of Potentially Avoidable Readmissions to an Oncology Service at a Safety Net Hospital.

Hospital readmissions occur commonly in those receiving cancer care and result in impaired quality of life and increased costs. Causes of readmission in safety net hospitals that serve vulnerable populations are not well understood. The primary goal of this project was to identify potentially avoidable and intervenable causes of readmissions to an urban safety net hospital. A retrospective chart review was performed on patients who were readmitted within 30 days of discharge from the hematology and oncology service at Boston Medical Center over the 6-month period between October 2018 and March 2019. Charts were reviewed by three internal medicine residents and discussed under the supervision of an attending oncologist. Two hundred ninety-one patient encounters involving 203 unique patients were identified in the 6-month study period. Of these 291 encounters, 80 encounters (27.5%) were followed by a readmission within 30 days and occurred in 61 (30.0%) unique patients. Nineteen (31.1%) of these 61 patients experienced two readmissions within 30 days of discharge. Twenty-five readmissions (31.3%) were classified as potentially avoidable, with the most common cause of potentially avoidable readmissions attributed to ascitic or pleural fluid reaccumulation (8, 32%). The majority of presumed nonpreventable readmissions were due to expected complications of cancer progression and treatment-related side effects. In conclusion, readmissions were common, and a modifiable reason for 30-day readmissions was identified. Addressing recurrent ascitic and pleural fluid reaccumulation in the outpatient setting could help to reduce inpatient hospital readmission on an inpatient oncology service.

Evaluation of Prognosticators and Treatment-Related Side Effects in Patients Irradiated Postoperatively for Endometrial Cancer.

Simple SummarySeveral trials sought to improve outcomes in endometrial cancer patients with multimodal strategies. Histopathological, clinical, and molecular tumor characteristics were demonstrated to correlate with outcomes. We tested the hypothesis that specific histopathological and clinical parameters are prognosticators for outcomes in patients irradiated postoperatively at our Gynecological Cancer Center. First, we found a significant influence of grading and nodal stage on outcomes. These findings underline the recommendations of more intense treatment in these patient groups, as reflected in current guidelines. Secondly, age had a significant influence on survival be it due to comorbidities and/or due to too hesitant treatment regimen in elderly. Thus, here, it should be aimed at particular treatment strategies. Lastly, we found low rates of side effects associated with brachytherapy and moderate rates of side effects associated with teletherapy. Overall, our study serves as basis for further improvement of treatment strategies and for conceptualization of clinical trials.Numerous clinical trials sought to improve outcomes in endometrial cancer patients with multimodal treatment strategies. We tested the hypothesis that specific histopathological and clinical parameters are prognosticators for outcomes at our Gynecological Cancer Center. A total of 203 patients (median age, 69.5 years) was included. They were irradiated postoperatively (n = 184: Brachytherapy, n = 19: Teletherapy) between 05/2007 and 03/2020. The median follow-up was 37.2 months. As statistical methods, we used the univariable Cox proportional hazards regression, and log-rank statistics. First, we found a significant influence of grading and nodal stage on outcomes. These findings underline the recommendations of more intense treatment in these patient groups, as already reflected in current guidelines. Secondly, we found that patient age had a significant influence on survival be it due to comorbidities and/or due to too hesitant treatment regimen in the elderly. Thus, it should be aimed at particular strategies in treatment of these patients. Lastly, we found very low rates of treatment-related side effects in patients treated with brachytherapy and moderate rates of side effects in patients treated with teletherapy. Overall, our study serves as basis for further improvement of treatment strategies and for conceptualization of clinical trials.

Novel vaccines for allergen-specific immunotherapy.

Purpose of reviewAllergen-specific immunotherapy (AIT) is a highly economic, effective and disease-modifying form of allergy treatment but requires accurate prescription and monitoring. New molecular approaches are currently under development to improve AIT by reducing treatment-related side effects, cumbersome protocols and patients’ compliance. We review the current advances regarding refined diagnosis for prescription and monitoring of AIT and the development of novel molecular vaccines for AIT. Finally, we discuss prophylactic application of AIT.Recent findingsThere is evidence that molecular allergy diagnosis not only assists in the prescription and monitoring of AIT but also allows a refined selection of patients to increase the likelihood of treatment success. New data regarding the effects of AIT treatment with traditional allergen extracts by alternative routes have become available. Experimental approaches for AIT, such as virus-like particles and cell-based treatments have been described. New results from clinical trials performed with recombinant hypoallergens and passive immunization with allergen-specific antibodies highlight the importance of allergen-specific IgG antibodies for the effect of AIT and indicate opportunities for preventive allergen-specific vaccination.SummaryMolecular allergy diagnosis is useful for the prescription and monitoring of AIT and may improve the success of AIT. Results with molecular allergy vaccines and by passive immunization with allergen-specific IgG antibodies indicate the importance of allergen-specific IgG capable of blocking allergen recognition by IgE and IgE-mediated allergic inflammation as important mechanism for the success of AIT. New molecular vaccines may pave the road towards prophylactic allergen-specific vaccination.
