ABSTRACT

OBJECTIVES: The aim of this study was to identify and compare prognostic factors, management strategies, and outcomes of very locally advanced cervical cancer (CC) (i.e., stage IVA) and metastatic CC (i.e., stage IVB). METHOD: A retrospective review was conducted based on all consecutive patients treatedfor stage IV CC in a comprehensive cancer care centre between 2004 and 2017. RESULTS: Sixty-eight patients were included. Performance status (PS) was ≥2 for 35.9%. Median age at diagnosis was 60.5. There were 24 stage IVA CC (35.3%) and 44 stage IVB CC (64.7%). Seventeen patients with stage IVB CC had only para-aortic lymph node metastases (38.6%), 13 had only distant metastases (29.5%), and 14 had both (31.8%). Patients with stage IVA CC experienced a radiotherapy with curative intent (n = 14, 58.3%) +/- concomitant chemotherapy, or a palliative treatment (n = 10, 41.7%). Twenty-three patients with stage IVB CC received a prior chemotherapy (52.3%), 11 a primary concomitant chemoradiation (25%), and 10 a palliative treatment (22.7%). The mean follow-up was 18.0 months. The 5-year overall survival was 5.1% for stage IVA (95% CI = 0.7-33.9), and 10.5% for stage IVB (95% CI = 3.7-29.7). In multivariate analysis, PS >1 was identified as a poor prognostic factor of disease-specific survival for stage IVA CC. PS >1 and pelvic lymph node involvement were identified as poor prognostic factors of overall survival and disease-specific survival for stage IVB CC. CONCLUSIONS: In daily clinical practice, outcomes of stages IV CC are poor. Treatment of advanced and metastatic CC remains challenging. New management strategies are needed, as well as efficient preventive strategies.

ABSTRACT

Background: Phase II trials are designed to assess the efficacy/toxicity ratio of experimental treatments and select those worth being tested in phase III trials. Although crucial limitations were identified when concurrent chemoradiation (cCRT) phase III trials characteristics were assessed, features of cCRT phase II trials have never been reported. The objective was to describe features of all cCRT phase II trials. Methods and material: Requests were performed in the Medline database (via PubMed). The latest update was performed in April 2016, using the following MESH terms: 'clinical trials: phase II as topic', 'chemoradiotherapy'. Results: Four hundred and fifty-eight cCRT phase II trials were identified. They were mainly multicenter (51.5%), single arm studies (77.7%) published after 2011 (55.0%). The median number of included patients was 52. Primary endpoints were mainly response rate (20.5%), pathological complete response (14.4%) and overall survival (12.6%). The primary endpoint was not defined in 22% of studies. Tumors were mostly lung (23.1%), head and neck (20.3%), colorectal (16.6%) and esophagogastric cancer (14.6%) treated at a locally advanced setting (81.7%). 55.2% of trials used 3D-conformal radiotherapy and 9.1% intensity-modulated radiotherapy, mainly with normo-fractionation (82.0% of the 573 arms with radiotherapy). Radiation technique was not reported in 19.9% of studies. Associated anticancer drugs (563 arms) were mainly conventional chemotherapies (559 arms): cisplatin (46.2%) and 5-fluorouracil (28.3%). Non cytotoxic agents (targeted therapies, immunotherapies) were tested in 97 arms (17%). With a median follow-up of 31 months, acute grades 3-5 were reported in 98.5% of studies and late toxicities in 44.5%. Follow-up was not reported in 17% of studies. Conclusions: cCRT phase II trials featured severe limitations, with outdated radiation techniques, insufficient reporting of crucial data and a small number of included patients. This certainly limited the impact of conclusions and hindered the development of successful phase III trials.

ABSTRACT

Molecular targeted therapies (TT) are the cornerstone of metastatic renal cell carcinoma (RCC) treatment. There is a paucity of data on the safety of the radiotherapy (RT)-TT association in a sequential or a concomitant setting. The aim of the present study is to retrospectively assess the safety of the RT-TT association. From 2006 to 2014, data from 84 consecutive patients treated with RT and TT for metastatic RCC were retrospectively collected. RT-TT sequential and concomitant associations were, respectively, defined by a time interval of more than five TT half-lives and less than or equal to five TT half-lives between the last TT administration and RT initiation. Toxicities in the fields of RT were assessed systematically. As many patients received several TT and RT courses, 136 RT-TT associations were analyzed, with 66 sequential and 70 concomitant schemes. RT was mainly delivered on bone (75%) and brain metastases (14.7%). TT were tyrosine kinase inhibitors (73.5%), mTOR inhibitors (19.8%), and monoclonal antibodies (6.7%). With a median follow-up of 9.5 months, whatever the sequence, no grade≥4 toxicity was reported. Two grade 3 toxicities were reported with sequential (3%) and concomitant (2.9%) RT-TT, respectively. Sequential or concomitant RT-TT associations in metastatic RCC do not seem to cause major toxicity.

ABSTRACT

BACKGROUND: Trabectedin plus pegylated liposomal doxorubicin (PLD) proved efficacious as second-line treatment for patients with recurrent ovarian cancer (ROC). METHODS: We report a single-center retrospective analysis of the efficacy and tolerance of trabectedin 1.1 mg/m2 every 3 weeks in a cohort of real-life ROC patients. RESULTS: From February 2012 to January 2014, 17 patients were treated with trabectedin alone or combined with PLD. Median age was 61 years (range: 48-78). Performance status was 0-1 in 16 patients (94%). Disease response rate was 53% and disease control rate was 76%. At the end of the follow-up, 8 patients (47%) were alive. Median overall survival was 17.6 months (95% CI 13.6 to not reached). Median progression-free survival was 6.7 months (95% CI 5.4-10.0). The most frequent grade 3-4 toxicities were neutropenia (n = 4, 24%) and nausea/vomiting (n = 4, 24%). CONCLUSION: Trabectedin combined with PLD seems efficient in and well tolerated by real-life ROC patients.

ABSTRACT

BACKGROUND: We studied the efficacy and safety of cabazitaxel in unselected real-life patients. PATIENTS AND METHODS: We retrospectively investigated all patients with metastatic prostate cancer (mPC) treated with cabazitaxel 25 mg/m2 i.v. every 3 weeks combined with oral prednisolone (10 mg once daily) after first-line docetaxel chemotherapy. Study issues were to report patient characteristics and cabazitaxel data in terms of tolerance and efficacy. Overall survival (OS) and progression-free survival (PFS) were evaluated using the Kaplan-Meier method. All data were compared with TROPIC results. RESULTS: From 2011 to 2014, 41 patients received cabazitaxel; 15 patients (37%) had a performance status (PS) ≥2 versus 7% (p < 0.0001) in TROPIC, and 38 patients (93%) presented a Gleason score ≥7 at baseline (vs. 60%; p < 0.0001). All patients had metastatic disease at baseline. Previous therapies were radiotherapy in 17 patients (41 vs. 61%; p = 0.01) and surgery in 24 patients (59 vs. 52%; p = 0.4). The median number of cabazitaxel cycles was 5 (1-10) versus 6 (3-10) in TROPIC. Five patients completed 10 cycles of cabazitaxel (12%) versus 28% in TROPIC (p = 0.03). Toxicities were anemia (12 patients, 29%), diarrhea (9 patients, 22%), nausea (7 patients, 17%), pain (6 patients, 15%), sepsis (4 patients, 10%), neutropenia (3 patients, 7%) and urinary tract infection (1 patient, 2%). The tumor response rate was 19.5 versus 14.4% in TROPIC (nonsignificant). PFS was 4.5 months (95% CI 3.3-6.4) in our analysis and 2.8 months (95% CI 2.4-3.0) in TROPIC. OS was 12.1 months (95% CI 9.2 to not reached) and 15.1 months (95% CI 14.1-16.3), respectively. CONCLUSION: In our unselected mPC patients with poorer baseline clinical conditions and aggressive disease, cabazitaxel seems efficient and not more toxic than in the TROPIC study.

ABSTRACT

BACKGROUND: The elderly population in Western countries is growing and constitutes a public health issue. Concomitantly, age-related diseases such as cancer increase. There are few data on the efficacy, tolerability and toxicity of specific anticancer therapy in the very elderly patients; therefore, their management is not standardized. METHODS: In this bi-institutional study, we reviewed medical records of patients who received or continued specific anticancer therapy beyond the age of 90 years. Geriatric assessment was not reported for our patients. Twelve patients were enrolled. Their general health condition was good, and half of them were living in elderly institutions. Ten patients had a solid tumor and 2 were treated for hematological malignancies. Most were diagnosed with a locally advanced or metastatic disease, and the goal of treatment was curative for only 1 patient. Six patients received chemotherapy as first-line treatment, 4 patients received targeted therapy and 2 received concomitant chemoradiation. Four patients received a second-line treatment. RESULTS: Despite a significant reduction in treatment posology in half of the patients, 8 acute grade 3/4 toxicities were reported and 2 patients died of treatment-related septic shock. Median duration of first-line treatment was 3.2 months, and progression-free survival ranged from 18 to 311 days. Overall survival ranged from 18 days to 11 years. CONCLUSION: Aging is a heterogeneous process, and management of elderly patients is a multidisciplinary approach. Geriatric assessment helps to identify older patients with a higher risk of morbidity/mortality and allows to assess the risks and benefits of specific anticancer therapy. The choice of treatment should be based primarily on the expected symptomatic benefit, and treatment should not compromise the quality of life.

ABSTRACT

OBJECTIVE: Several studies have demonstrated that daily physical activity (PA) prevents the development of breast cancer. Our objective was to examine the relationship between PA and clinical and biological tumor characteristics in breast cancer patients in order to determine the impact of energy expenditure (EE) on tumor prognosis. METHODS: We pooled data from two prospective studies, including a total of 121 breast cancer patients. The measure of PA was done using the self-completion Population Physical Activity Questionnaire, which was answered by each patient. RESULTS: Ten patients harbored triple negative (TN) tumors. The mean body mass index (BMI) in the general population and in patients with TN tumors was 24.3 and 25.6, respectively. The mean daily EE (DEE) was 10,266 kJ×24 h(-1) in the general population and 11,212 kJ×24 h(-1) in patients with TN tumors. In the whole population, there was an inverse statistical correlation between BMI and DEE, rest, low PA, and high PA (p=0.0002, p=0.003, p<0001, and p=0.03, respectively). There was a positive correlation between negative estrogen receptor status and intensive PA (p=0.041) and DEE (p=0.007). For TN tumors, there was no significant correlation between BMI and categories of EE. CONCLUSIONS: Lifestyle (weight regulation, PA) should be adapted and personalized according to biological, clinical, and epidemiological characteristics of the tumors.

ABSTRACT

In the field of radiotherapy, there is very little scientific data on the management of nonagenarians, especially in patients aged 90 years or more and with head and neck cancer (HNC). We made one of the first retrospective study of the feasibility and safety of radiotherapy in this population with HNC. Records of radiotherapy coming from four health facilities were studied to include all nonagenarian patients with HNC in the last 10 years and who received radiation therapy. We analyzed patient characteristics and primary cancers, as well as objective of the treatment (curative or palliative), efficacy and toxicity. Twenty patients receiving radiotherapy were identified; mean age was 93.2 years (standard deviation 2.8). Treatment was given with curative and palliative intent in 40 and 60 % of cases, respectively. The most common primary tumors were tumors of the salivary glands (30 % of cases), oral cavity tumors (25 % of cases) and thyroid tumors (15 % of cases). Median total prescribed dose was 47.5 Gy (12-70 Gy). Median number of delivered fractions was 18.5 (2-35 fractions). All patients received intensive supportive care during radiotherapy. Toxicities were mild to moderate. Radiotherapy could not be completed for four patients (20 % of cases). One patient developed grade 1-2 delayed toxicities. At the last follow-up, only four patients (20 % of cases) were alive. Cancer was cause of death in most cases. Radiotherapy may be performed for the nonagenarians with HNC. The total dose and fractionation must be adjusted to optimize the tolerance. However, the prognosis remains very poor, cancer being the main cause of death. Research of geriatric vulnerabilities prior to any treatment, in the context of a comprehensive geriatric assessment, is still recommended to select patients for radiotherapy.

ABSTRACT

We report the case of an 80-year-old patient who presented with a progressive prostate metastatic cancer with poor performance status. The patient had already benefitted from docetaxel and abiraterone. A new line of chemotherapy by cabazitaxel was started with good response, and there was a dramatic improvement in general status and pain symptoms. Age and performance status alone should not be limiting decision factors for elderly cancer patients.

ABSTRACT

OBJECTIVES: We aimed at describing and assessing the quality of reporting in all published prospective trials about radiosurgery (SRS) and stereotactic body radiotherapy (SBRT). METHODS: The Medline database was searched for. The reporting of study design, patients' and radiotherapy characteristics, previous and concurrent cancer treatments, acute and late toxicities and assessment of quality of life were collected. RESULTS: 114 articles - published between 1989 and 2019 - were analysed. 21 trials were randomised (18.4%). Randomisation information was unavailable in 59.6% of the publications. Data about randomisation, ITT analysis and whether the study was multicentre or not, had been significantly less reported during the 2010-2019 publication period than before (respectively 29.4% vs 57.4% (p < 0.001), 20.6% vs 57.4% (p < 0.001), 48.5% vs 68.1% (p < 0.001). 89.5% of the articles reported the number of included patients. Information about radiation total dose was available in 86% of cases and dose per fraction in 78.1%. Regarding the method of dose prescription, the prescription isodose was the most reported information (58.8%). The reporting of radiotherapy characteristics did not improve during the 2010 s-2019s. Acute and late high-grade toxicity was reported in 37.7 and 30.7%, respectively. Their reporting decreased in recent period, especially for all-grade late toxicities (p = 0.044). CONCLUSION: It seems necessary to meet stricter specifications to improve the quality of reporting. ADVANCES IN KNOWLEDGE: Our work results in one of the rare analyses of radiosurgery and SBRT publications. Literature must include necessary information to first, ensure treatments can be compared and reproduced and secondly, to permit to decide on new standards of care.

ABSTRACT

BACKGROUND: This retrospective study was conducted to: (1) provide more modern data on real-life local management of metastatic rectal cancer; (2) compare therapeutic strategies; and (3) identify prognostic factors of local failure, overall survival and progression-free survival. METHODS: Data about efficacy and acute toxicity were collected. Patients were diagnosed with metastatic rectal cancer between 2004 and 2015, and were treated at least with radiotherapy. Local failure, overall survival and progression-free survival were correlated with patient, tumour and treatment characteristics using univariate and multivariate analyses. RESULTS: Data of 148 consecutive patients with metastatic rectal cancer were analysed. Median follow-up was 19 months. Median overall survival was 16 months. All patients received local radiotherapy, with a median equivalent 2 Gy per fraction dose of 47.7 Gy. Rectal surgery was performed in 97 patients (65.6%). The majority of patients (86/97, 88.7%) received pre-operative chemoradiation. In multivariate analysis, rectal surgery was found to be the only independent predictor of increased overall survival (24.6 vs 7.1 months, p <0.001). Of the patients undergoing surgical treatment, 22.8% presented with significant complications that required a delay of systemic treatment. Grade 3-4 acute radiation therapy-related toxicities were observed in 6.1% of patients, mainly gastrointestinal toxicities (5.4%). CONCLUSION: Rectal surgery was a key predictive factor of increased progression-free survival and overall survival in patients receiving at least local radiotherapy. In our series of real-life patients, local surgery and radiation seemed as well tolerated as reported in selected phase III non-metastatic rectal cancer patients. These data suggested that local management could be beneficial for metastatic rectal cancer patients.

ABSTRACT

The aim of this study was to propose a methodology for the assessment of non-inferiority with meta-analysis. Assessment of hypofractionated RT in prostate and breast cancers is used as an illustrative example. Non-inferiority assessment of an experimental treatment versus an active comparator should rely on two elements: (1) an estimation of experimental treatment's effect versus the active comparator based on a meta-analysis of randomized controlled trials and (2) the value of an objective non-inferiority margin. This margin can be defined using the reported effect of active comparator and the percentage of the active comparator's effect that is desired to be preserved. Non-inferiority can then be assessed by comparing the upper bound of the 95% confidence interval of experimental treatment's effect to the value of the objective non-inferiority margin. Application to hypofractionated RT in breast cancer showed that hypofractionated whole breast irradiation (HWBI) appeared to be non-inferior to conventionally fractionated RT for local recurrence. This was not the case for accelerated partial breast irradiation (APBI). Concerning overall survival, non-inferiority could not be claimed for either HWBI or APBI. For prostate cancer, the lack of demonstrated significant superiority of conventional RT versus no RT precluded any conclusion regarding non-inferiority of hypofractionated RT.

ABSTRACT

OBJECTIVES: An unexpected promising effect of low molecular weight heparins (LMWHs) on survival in patients with cancer was observed in early trials in post hoc subgroup analyses but not found in more recent trials. To highlight a possible regression over time toward the lack of the antitumoral effect of LMWHs, we performed a cumulative meta-analysis of survival data from randomized controlled trials (RCTs). STUDY DESIGN AND SETTING: Medical databases were searched to identify RCTs comparing, in patients with cancer, LMWHs with placebo or no treatment in patients free of venous thromboembolism (VTE), or to vitamin K antagonists in patients who experienced an acute VTE in overall survival. The cumulative hazard ratio (HR) was estimated after each study inclusion in chronological order. RESULTS: Twenty-three studies (12,970 patients) were included. The cumulative meta-analysis of the earlier trials showed a significant improvement in overall survival with LMWHs. This apparent benefit then gradually regressed over time toward an absence of the effect of LMWHs on survival (HR: 0.98 [95% confidence interval, 0.93; 1.03]). CONCLUSION: Despite supportive experimental data and early clinical findings, the promising antitumoral effect of LMWHs in patients with cancer gradually vanished over time toward a lack of impact on overall survival. This result suggests 'p-hacking' and selective reporting of the positive results from post hoc subgroup analyses in the early studies.

ABSTRACT

BACKGROUND: Glioblastoma multiforme (GBM) has a poor prognosis despite a multi modal treatment that includes normofractionated radiotherapy. So, various hypofractionated alternatives to normofractionated RT have been tested to improve such prognosis. There is need of systematic review and meta-analysis to analyse the literature properly and maybe generalised the use of hypofractionation. The aim of this study was first, to perform a meta-analysis of all controlled trials testing the impact of hypofractionation on survival without age restriction and secondly, to analyse data from all non-comparative trials testing the impact of hypofractionation, radiosurgery and hypofractionated stereotactic RT in first line. MATERIALS/METHODS: We searched Medline, Embase and Cochrane databases to identify all publications testing the impact of hypofractionation in glioblastoma between 1985 and March 2020. Combined hazard ratio from comparative studies was calculated for overall survival. The impact of study design, age and use of adjuvant temozolomide was explored by stratification. Meta-regressions were performed to determine the impact of prognostic factors. RESULTS: 2283 publications were identified. Eleven comparative trials were included. No impact on overall survival was evidenced (HR: 1.07, 95%CI: 0.89-1.28) without age restriction. The analysis of non-comparative literature revealed heterogeneous outcomes with limited quality of reporting. Concurrent chemotherapy, completion of surgery, immobilization device, isodose of prescription, and prescribed dose (depending on tumour volume) were poorly described. However, results on survival are encouraging and were correlated with the percentage of resected patients and with patients age but not with median dose. CONCLUSIONS: Because few trials were randomized and because the limited quality of reporting, it is difficult to define the place of hypofactionation in glioblastoma. In first line, hypofractionation resulted in comparable survival outcome with the benefit of a shortened duration. The method used to assess hypofractionation needs to be improved.

ABSTRACT

Stereotactic body radiotherapy (SBRT) is a young technology that can deliver a high dose of radiation to the target, utilizing either a single dose or a small number of fractions with a high degree of precision within the body. Various technical solutions co-exist nowadays, with particular features, possibilities and limitations. Health care authorities have currently validated SBRT in a very limited number of locations, but many indications are still under investigation. It is therefore challenging to accurately appreciate the SBRT therapeutic index, its place and its role within the anticancer therapeutic arsenal. The aim of the present review is to provide SBRT definitions, current indications, and summarize the future ways of research. There are three validated indications for SBRT: un-resecable T1-T2 non small cell lung cancer, <3 slow-growing pulmonary metastases secondary to a stabilized primary, and the tumours located close to the medulla. In other situations, the benefit of SBRT is still to be demonstrated. One of the most promising way of research is the ablative treatment of oligo metastatic cancers, with recent studies suggesting a survival benefit. Furthermore, the most recent data suggest that SBRT is safe. Finally, the SBRT combined with immune therapies is promising, since it could theoretically trigger the adaptative anticancer response.

ABSTRACT

Human oncogenic papillomaviruses (HPV) have an increasingly prominent role in the genesis of many cancers. The oncogenic mechanisms associated with HPV are now better known and make it possible to explain the etiopathogenesis of the association. HPV status is now sought for certain cancers and conditions both prognosis and management of patients. Preventive antiviral vaccination has become a real public health issue and aims to effectively reduce the prevalence of cervical, anal and oropharynx cancer, HPV-associated. However, vaccination against HPV still lags behind. The purpose of this review is to redefine the involvement of HPV in several cancers as well as current therapeutic challenges of HPV-related cancers, notably in term of prevention.

ABSTRACT

Innovation in radiotherapy should meet multiple challenges, both technically, biologically, clinically and socially. Scientific, technological and biological advances have resulted in major changes in the implementation, indications, and therapeutic index of radiotherapy over the last century. Based on technical innovations (conformal radiotherapy, intensity modulation, CBCT, stereotactic body radiotherapy and MRI embedded system) and knowledge in cancer biology ("oxygen effect", "checkpoints", targeted therapies, molecular profiles and immunotherapy) highlighted in recent decades, the news in radiotherapy is rich and varied. The 2018 news are particularly focused in the role of hypofractionation in prostate cancer, the use of stereotactic body radiotherapy in oligometastatic patients, the possibility of de-intensify treatment in HPV-related oropharynx cancer, and the combination of short-term androgen deprivation to prostate bed salvage radiotherapy. The present manuscript reviews the 2018 latest advances.

ABSTRACT

Triple-negative breast cancer (TNBC) (estrogen receptor-negative, progesterone receptor-negative, and HER2-negative) is viewed as an aggressive subgroup of breast cancer. Treating patients with TNBC remains clinically challenging. It's now well established than radiation therapy is able to improve locoregional control in breast cancer patients both after breast conserving surgery or mastectomy, with positive impact in high-risk patients for long-term survival. Biologic characterization of breast tumor different subtypes, in particular the heterogeneous subtype of TNBC could permit to adapt the treatment plan. In the present review, summarizing the molecular types, we describe clinical features and postoperative radiotherapy current situation for TNBC, and we provide new strategies and directions through an adapted radiation therapy.

ABSTRACT

BACKGROUND: Despite screening campaigns, cervical cancers remain among the most prevalent malignancies and carry significant mortality, especially in developing countries. Most studies report outcomes of patients receiving the usual standard of care. It is possible that these selected patients may not correctly represent patients in a real-world setting, which may be a limitation in interpreting outcomes. This study was undertaken to identify prognostic factors, management strategies and outcomes of locally advanced cervical cancers (LACC) treated in daily clinical practice. METHODS: Medical files of all consecutive patients treated with curative intent for LACC in a French Cancer Care Center between 2004 and 2014 were reviewed retrospectively. RESULTS: Ninety-four patients were identified. Performance status was ≥ 2 in 10.6%. Median age at diagnosis was 63.0. Based on the International Federation of Gynecology and Obstetrics classification, tumours were classified as follows: 10.6% IB2, 22.3% IIA, 51.0% IIB, 4.3% IIIA and 11.7% IIIB. Pelvic lymph nodes were involved in 34.0% of cases. Radiotherapy was delivered for all patients. Radiotherapy technique was intensity modulated radiation therapy or volumetric modulated arc therapy in 39.4% of cases. A concurrent cisplatin chemotherapy was delivered in 68.1% of patients. Brachytherapy was performed in 77.7% of cases. The recommended standard care (concurrent chemoradiotherapy with at least five chemotherapy cycles during radiotherapy, followed by brachytherapy) was delivered in 43.6%. The median overall treatment time was 56 days. Complete tumour sterilisation was achieved in 55.2% of cases. Mean follow-up was 54.3 months. Local recurrence rate was 18.1%. Five-year overall survival was 61.9% (95% Confident Interval (CI) = 52.3-73.2) and five-year disease-specific survival was 68.5% (95% CI = 59.2-79.2). Poor performance status, lymph nodes metastasis and absence of concurrent chemotherapy were identified as poor prognostic factors in multivariate analysis. CONCLUSIONS: Less than 50% of patients received the standard care. Because LACC patients and disease are heterogeneous, treatment tailoring appears to be common in current clinical practice. However, guidelines for tailoring management are not currently available. More data about real-world settings are required in order to to optimise clinical trials' aims and designs, and make them translatable in daily clinical practice. TRIAL REGISTRATION: retrospectively registered.
