RESUMEN
Background: Children with hemato-oncological diseases or following stem cell transplantation (SCT) are at high risk for life-threatening infections; sepsis in this population constitutes a substantial proportion of pediatric intensive care unit (PICU) admissions. The current pediatric prognostic scoring tools to evaluate illness severity and mortality risk are designed for the general pediatric population and may not be adequate for this vulnerable subpopulation. Methods: Retrospective analysis was performed on all PICU admissions for sepsis in children with hemato-oncological diseases or post-SCT, in a single tertiary pediatric hospital between 2008 and 2021 (n = 233). We collected and analyzed demographic, clinical, and laboratory data and outcomes for all patients, and evaluated the accuracy of two major prognostic scoring tools, the Pediatric Logistic Organ Dysfunction-2 (PELOD-2) and the Pediatric Risk of Mortality III (PRISM III). Furthermore, we created a new risk-assessment model that contains additional parameters uniquely relevant to this population. Results: The survival rate for the cohort was 83%. The predictive accuracies of PELOD-2 and PRISM III, as determined by the area under the curve (AUC), were 83% and 78%, respectively. Nine new parameters were identified as clinically significant: age, SCT, viral infection, fungal infection, central venous line removal, vasoactive inotropic score, bilirubin level, C-reactive protein level, and prolonged neutropenia. Unique scoring systems were established by the integration of these new parameters into the algorithm; the new systems significantly improved their predictive accuracy to 91% (p = 0.01) and 89% (p < 0.001), respectively. Conclusions: The predictive accuracies (AUC) of the PELOD-2 and PRISM III scores are limited in children with hemato-oncological diseases admitted to PICU with sepsis. These results highlight the need to develop a risk-assessment tool adjusted to this special population. Such new scoring should represent their unique characteristics including their degree of immunosuppression and be validated in a large multi-center prospective study.

INTRODUCTION: Personalized treatment helps one achieve optimal outcomes in patients with non-small cell lung cancer (NSCLC). Understanding patients' survival prognoses in a palliative situation like intracerebral metastases is critical. A new survival score, the WBRT-30-NSCLC, was developed for patients with intracerebral metastases from NSCLC. METHODS: Eight factors were investigated in 157 patients receiving 10 × 3 Gy of whole-brain radiotherapy (WBRT) including age, gender, Karnofsky performance score (KPS), interval from diagnosis of NSCLC to WBRT, pre-WBRT systemic treatment, primary tumor control, number of intracerebral metastases, and metastasis outside the brain. Factors significant (p < 0.05) or showing a trend (p < 0.08) on multivariate analysis were used for the WBRT-30-NSCLC. Patient scores were derived by adding factor scores (6-month survival rates divided by 10). WBRT-30-NSCLC was compared to other scores for intracerebral metastases from NSCLC. RESULTS: On multivariate analysis, age (p = 0.005), KPS (p < 0.001), systemic treatment (p = 0.018), and metastasis outside the brain (p < 0.001) were significant; number of intracerebral metastases (p = 0.075) showed a trend. Four groups were designed (912, 1317, 1820, and 22 points) with 6-month survival rates of 3, 26, 65, and 100%. Positive predictive value (PPV) to predict death ≤ 6 months after WBRT was 97% (updated DS-GPA classification 86%, Rades-NSCLC 88%), and PPV to predict survival ≥ 6 months was 100% (updated DS-GPA 78%, Rades-NSCLC 74%). CONCLUSIONS: The WBRT-30-NSCLC appeared very precise in identifying patients with intracerebral metastases from NSCLC dying ≤ 6 months or surviving ≥ 6 months. It appeared more precise than previous scores and can support physicians developing personalized treatment regimens.

Palliative radiotherapy improves lung cancer related symptoms. Prognosis should be taken into account when deciding about fractionation. In this study, prognostic factors derived from multivariate analysis were used to assign a point sum reflecting 6-month survival. Four prognostic groups were compared. Performance status, lactate dehydrogenase, C-reactive protein, liver/adrenal gland metastases, and extrathoracic disease status significantly predicted survival and formed the basis of the score. The four groups had a median survival of 0.8, 1.6, 3.3, and 10.5 months (6-month survival 0, 10, 30, 70%; 12-month survival 0, 0, 12, 40%; p = 0.0001), respectively. In the unfavorable group best supportive care might be preferable.

Melanoma brain metastases (MBM) are common in patients with stage IV disease. For Gamma Knife radiosurgery (GKRS) on MBM, risk scores such as RPA and melanoma-GPA aid to identify prognostic subgroups. This study aimed to validate the overall survival (OS) risk score developed by Chowdhury et al. in our center's patient cohort. A total of 104 MBM patients were treated with GKRS between 1/1/2002 and 31/12/2014 in our institution. Patients were categorized according to RPA, melanoma-GPA and Chowdhury OS score. The Kaplan-Meier method was used to estimate overall survival, and predicted survival probabilities were calculated for calibration. Cox proportional hazards regressions were performed to identify additional risk factors. Overall, median follow-up time was 80 months, while median OS (mOS) after GKRS was 6 months. Stratified according to the Chowdhury OS score, mOS in the high, medium and low risk group was 3.4, 7.1, and 10.0 months, respectively. The addition of other patient or disease characteristics to the Chowdhury OS model did not improve its performance. The C-index of the melanoma-GPA was 0.46 while the Chowdhury OS had an index of 0.67. In comparison with the RPA and melanoma-GPA, the Chowdhury OS score more accurately distinguished between separate risk groups among patients with MBM treated with GKRS. Contrary to the original study by Chowdhury, follow-up time was sufficient here for the low-risk group to reach the mOS time of 10 months.

Nearly all information about patients with chronic lymphocytic leukaemia (CLL) who develop diffuse large B-cell lymphoma [Richter syndrome (RS)] is derived from retrospective case series or patients treated on clinical trials. We used the Mayo Clinic CLL Database to identify patients with newly diagnosed CLL between January 2000 and July 2011. Individuals who developed biopsy-proven RS during follow-up were identified. After a median follow-up of 4 years, 37/1641 (2·3%) CLL patients developed RS. The rate of RS was approximately 0·5%/year. Risk of RS was associated with advanced Rai stage at diagnosis (P < 0·001), high-risk genetic abnormalitites on fluorescence in situ hybridization (P < 0·0001), unmutated IGHV (P = 0·003), and expression of ZAP70 (P = 0·02) and CD38 (P = 0·001). The rate of RS doubled in patients after treatment for CLL (1%/year). Stereotyped B-cell receptors (odds-ratio = 4·2; P = 0·01) but not IGHV4-39 family usage was associated with increased risk of RS. Treatment with combination of purine analogues and alkylating agents increased the risk of RS three-fold (odds-ratio = 3·26, P = 0·0003). Median survival after RS diagnosis was 2·1 years. The RS prognosis score stratified patients into three risk groups with median survivals of 0·5 years, 2·1 years and not reached. Both underlying characteristics of the CLL clone and subsequent CLL therapy influence the risk of RS. Survival after RS remains poor and new therapies are needed.

Worldwide and in India head and neck malignancies are a major contributor to cancer mortality and morbidity. Tongue cancer predominates oral cavity cancers worldwide but in India it comes next to buccal mucosa. OPD patients after completing treatment tend to ask about the prognosis of their disease where they want an objective answer to "How long will I live?" His scoring system is intended to answer this question and guide patients for adjuvant therapy. This study enrolled all patients between 20 and 85 years old with a history of tobacco chewing at least for the last 1 year before diagnosis. Patients should have primary tongue cancer amenable to surgical resection. For survival calculation, date of diagnosis was taken as reference time. Using Kaplan-Meier survival analysis, clinicopathological factors significantly associated with survival were ascertained. Then using logit regression, a scoring system predicting patient survival in years based on clinicopathological risk factors was formulated and internal validation was done. A total 241 were enrolled and there were 69 cancer-related deaths. T stage, N stage, LVSI, and DOI were found to be significantly associated with cancer-related survival in tongue cancer patients. Another factor affecting survival was defaulting adjuvant radiation therapy. Using these variables, a survival predicting score was developed. On internal validation and regression, the score was found 80% accurate with error limits ± 6 months. It is a concise comprehensive score applicable on Indian population with history of tobacco chewing. It will not only help clinicians to tell patients about their survival expectancy but also help to counsel them for adjuvant therapy. However, external validation and if required recalibration incorporating other factors need to be done for this score.
RESUMEN
PURPOSE: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is a complex and high-risk life support modality used in severe cardiorespiratory failure. ECMO survival scores are used clinically for patient prognostication and outcomes risk adjustment. This study aims to create the first artificial intelligence (AI)-driven ECMO survival score to predict in-hospital mortality based on a large international patient cohort. METHODS: A deep neural network, ECMO Predictive Algorithm (ECMO PAL) was trained on a retrospective cohort of 18,167 patients from the international Extracorporeal Life Support Organisation (ELSO) registry (2017-2020), and performance was measured using fivefold cross-validation. External validation was performed on all adult registry patients from 2021 (N = 5015) and compared against existing prognostication scores: SAVE, Modified SAVE, and ECMO ACCEPTS for predicting in-hospital mortality. RESULTS: Mean age was 56.8 ± 15.1 years, with 66.7% of patients being male and 50.2% having a pre-ECMO cardiac arrest. Cross-validation demonstrated an inhospital mortality sensitivity and precision of 82.1 ± 0.2% and 77.6 ± 0.2%, respectively. Validation accuracy was only 2.8% lower than training accuracy, reducing from 75.5% to 72.7% [99% confidence interval (CI) 71.1-74.3%]. ECMO PAL accuracy outperformed the ECMO ACCEPTS (54.7%), SAVE (61.1%), and Modified SAVE (62%) scores. CONCLUSIONS: ECMO PAL is the first AI-powered ECMO survival score trained and validated on large international patient cohorts. ECMO PAL demonstrated high generalisability across ECMO regions and outperformed existing, widely used scores. Beyond ECMO, this study highlights how large international registry data can be leveraged for AI prognostication for complex critical care therapies.

BACKGROUND/AIM: Very elderly patients may benefit from individualized treatment. A survival score was created for patients aged 80+ receiving radiosurgery or fractionated stereotactic radiotherapy for 1-2 brain metastases. PATIENTS AND METHODS: Thirteen patients were retrospectively evaluated. Characteristics showing significant associations with survival or trends were used for analysis. Prognostic groups were calculated from scoring points of these characteristics (0=worse, 1=better survival) added for each patient. RESULTS: Survival was significantly associated with performance score (p=0.010). Trends were found for histology (p=0.066) and diameter of lesions (p=0.071). Three groups were created (0, 1-2, 3 points) with 6-month survival rates of 0%, 56%, and 100% (p=0.025). Positive predictive values (PPVs) to predict death ≤6 months were 100% with the new score vs. not available and 50% with previous scores; PPVs regarding survival ≥6 were 100% vs. 75% and 67%. CONCLUSION: Given its limitations, the score was more precise than previous tools and can serve for orientation in patients aged 80+.

Survival scores are important for personalized treatment of bone metastases. Elderly patients are considered a separate group. Therefore, a specific score was developed for these patients. Elderly patients (≥65 years) irradiated for bone metastases were randomly assigned to the test (n = 174) or validation (n = 174) cohorts. Thirteen factors were retrospectively analyzed for survival. Factors showing significance (p < 0.05) or a trend (p < 0.06) in the multivariate analysis were used for the score. Based on 6-month survival rates, prognostic groups were formed. The score was compared to an existing tool developed in patients of any age. In the multivariate analysis, performance score, tumor type, and visceral metastases showed significance and gender was a trend. Three groups were designed (17, 18−25 and 27−28 points) with 6-month survival rates of 0%, 51%, and 100%. In the validation cohort, these rates were 9%, 55%, and 86%. Comparisons of prognostic groups between both cohorts did not reveal significant differences. In the test cohort, positive predictive values regarding death ≤6 and survival ≥6 months were 100% with the new score vs. 80% and 88% with the existing tool. The new score was more accurate demonstrating the importance of specific scores for elderly patients.
RESUMEN
BACKGROUND/AIM: In a previous study investigating radiotherapy for newly diagnosed glioblastoma multiforme (GBM), significant or almost significant associations with survival were found for performance status, upfront resection, O6-methylguanine-DNA methyl-transferase (MGMT) promoter methylation and unifocal GBM. This study aimed to create a survival score based on these factors. PATIENTS AND METHODS: Most of the 81 patients included received resection of GBM followed by radiochemotherapy (59.4 Gy/33 or 60 Gy/30 fractions). The previously identified predictors of survival were re-evaluated. Factors significantly associated with survival were used for the score. RESULTS: All factors were significantly associated with survival. For each factor, 0 points (less favorable survival) or 1 point (more favorable survival) were assigned and added for each patient. Three groups were designed, 0-1 (n=10), 2 (n=21) and 3-4 points (n=50); 12-month survival rates were 0%, 38% and 78% (p<0.001). CONCLUSION: A new survival score was created for patients requiring radiotherapy for GBM that can improve treatment personalization.

BACKGROUND/AIM: Patients with advanced squamous cell carcinoma of the head-and-neck (SCCHN) may be assigned to palliative irradiation. A survival score was developed for this group to support treatment personalization. PATIENTS AND METHODS: Seventy-eight patients who received palliative irradiation for SCCHN and had complete data regarding performance score, pre-radiotherapy hemoglobin levels, and main tumor site were included in this retrospective study. Six-month survival rates of these factors were divided by 10 (factor scores) and added for each patient (total patient scores). RESULTS: Total patient scores ranged between 8 and 15 points. Three groups were designed based on the 6-month survival rates, namely 8-9 (n=15), 11-13 (n=36), and 14-15 (n=27) points. Six-month survival rates were 13%, 28%, and 63%, and median survival times were 1, 2, and 11 months (p=0.001). CONCLUSION: A new survival score including three prognostic groups was developed. This new tool can help physicians when designing personalized treatments for patients with SCCHN scheduled for palliative irradiation.

Gliomas account for approximately 70% of primary brain tumors in adults. Of all gliomas, grade IV astrocytoma, also called glioblastoma, has the poorest overall survival, with <5% of patients surviving five years after diagnosis. Due to the aggressiveness, lethal nature, and impaired surgical accessibility of the tumor, early diagnosis of the tumor and, in addition, prediction of the patient's survival time are important. We hypothesize that combining the protein level values of highly recognizable glioblastoma serum biomarkers could help to achieve higher specificity and sensitivity in predicting glioma patient outcome as compared to single markers. The aim of this study was to select the most promising astrocytoma patient overall survival prediction variables from five secretory proteins-glial fibrillary acidic protein (GFAP), matrix metalloproteinase-2 (MMP-2), chitinase 3-like 1 (CHI3L1), osteopontin (OPN), and amphiregulin (AREG)-combining them with routinely used tumor markers to create a Patient Survival Score calculation tool. The study group consisted of 70 astrocytoma patients and 31 healthy controls. We demonstrated that integrating serum CHI3L1 and OPN protein level values and tumor isocitrate dehydrogenase 1 IDH1 mutational status into one parameter could predict low-grade astrocytoma patients' two-year survival with 93.8% accuracy.
RESUMEN
PURPOSE: To validate the clinical efficacy of the recently developed EUTOS long-term survival (ELTS) score in a real-world setting. PATIENTS AND METHODS: A total of 479 chronic myeloid leukemia (CML) patients treated with frontline imatinib between January 2010 and December 2017 were enrolled in this retrospective study. The ELTS score was evaluated on the end-points including complete cytogenetic response (CCyR), progression-free survival (PFS), overall survival (OS) and CML-related death, and the efficiency of the ELTS score was further compared with the historical Sokal, Hasford, EUTOS scores. RESULTS: With a median follow-up of 69 months (range, 9-112 months), 462 evaluable patients were stratified into the ELTS low-risk (n = 230), ELTS intermediate-risk (n = 168) and ELTS high-risk (n = 64) groups. For the regular assessment indicators like CCyR, PFS and OS, the ELTS scoring system could effectively identify the corresponding risk groups, similarly with the results provided by previous scoring systems. With respect to the CML-related death, the ELTS score could accurately identify a high-risk group with a significantly higher risk of dying of CML, and the 5-year cumulative incidence occurred in the ELTS high-, intermediate-, and low-risk groups was 11% (95% CI: 3-19%), 5% (95% CI: 1-9%) and 2% (95% CI: 0-4%), respectively. Most notably, the ELTS score outperformed the Sokal, Hasford and EUTOS scores without statistical difference among different risk groups. CONCLUSION: The ELTS score could effectively predict the prognosis of imatinib-treated CML patients in real-life settings.
RESUMEN
AIM: The aim of this study was to develop a score to predict the outcome for patients brought to hospital following out-of-hospital cardiac arrest (OHCA). METHODS: All patients recorded in the German Resuscitation Registry (GRR) who suffered OHCA 2010-2017, who had ROSC or ongoing CPR at hospital admission were included. The study population was divided into development (2010-2016: 7985) and validation dataset (2017: 1806). Binary logistic regression analysis was used to derive the score. The probability of hospital discharge with good neurological outcome was defined as 1/(1â¯+â¯e-X), where X is the weighted sum of independent variables. RESULTS: The following variables were found to have a significant positive (+) or negative (-) impact: age 61-70 years (-0·5), 71-80 (-0·9), 81-90 (-1·3) and >â¯=â¯91 (-2·3); initial PEA (-0·9) and asystole (-1·4); presumable trauma (-1·1); mechanical CPR (-0·3); application of adrenalin >â¯0â¯-â¯<â¯2â¯mg (-1·1), 2â¯-â¯<4â¯mg (-1·6), 4â¯-â¯<â¯6â¯mg (-2·1), 6â¯-â¯<â¯8â¯mg (-2·5) and >â¯=â¯8â¯mg (-2·8); pre emergency status without previous disease (+0·5) or minor disease (+0·2); location at nursing home (-0·6), working place/school (+0·7), doctor's office (+0·7) and public place (+0·3); application of amiodarone (+0·4); hospital admission with ongoing CPR (-1·9) or normotension (+0·4); witnessed arrest (+0·6); time from collapse until start CPR 2â¯-â¯<â¯10â¯min (-0·3) and >â¯=â¯10â¯min (-0·5); duration of CPR <5â¯min (+0·6). The AUC in the development dataset was 0·88 (95% CI 0·87-0·89) and in the validation dataset 0·88 (95% CI 0·86-0·90). CONCLUSION: The CaRdiac Arrest Survival Score (CRASS) represents a tool for calculating the probability of survival with good neurological function for patients brought to hospital following OHCA.

BACKGROUND: It is highly desirable to assess the probability of survival in sick neonatal foals upon admission. The foal survival score (FSS) is a published scoring system used to estimate the probability of survival in hospitalized neonatal foals <4 days old. HYPOTHESIS/OBJECTIVES: To evaluate the ability of the FSS to predict survival in older foals from a geographically different area compared to the original study. ANIMALS: Five-hundred ninety hospitalized neonatal foals ≤14 days of age. METHODS: Retrospective Danish-Swedish multicenter study that included details of signalment, history, clinical examination, laboratory results, necropsy findings, and outcome. Scores and score variables were compared between survivors and nonsurvivors using logistic regression. The optimal cutoff and its test parameters were calculated using a receiver operator characteristic curve. RESULTS: Prematurity, cold extremities, ≥2 infectious or inflammatory sites, blood glucose concentration, and total white blood cell counts were significantly associated with nonsurvival (P ≤ .02). The optimal cutoff to predict survival was ≥6, resulting in sensitivity 78%, specificity 58%, 92% positive predictive value, and 31% negative predictive value. The test performed equally well in foals <4 days old compared to those 4-14 days old. CONCLUSIONS AND CLINICAL IMPORTANCE: Using the suggested optimal cutoff of ≥6, the FSS performed moderately well and may aid in early determination of prognosis for survival. However, the FSS did perform differently in another population and therefore should be assessed under local conditions so that its diagnostic potential is not overestimated.

BACKGROUND: Stage III non-small cell lung cancer (NSCLC) represents a heterogeneous disease regarding principal patient- and tumor characteristics. A simple score may aid in personalizing multimodal therapy. METHODS: The data of 99 consecutive patients with performance status ECOG 0-1 treated until the end of 2016 with multimodal approach for inoperable NSCLC (UICC 7th edition stage IIIA/B) were evaluated. Patient- and tumor-related factors were examined for their impact on overall survival. Factors showing a negative association with prognosis were then included in the score. Three subgroups with low, intermediate and high-risk score were defined. The results were then validated in the prospective cohort, which includes 45 patients. RESULTS: Most Patients were treated with concurrent (78%) or sequential (11%) chemoradiotherapy. 53% received induction chemotherapy. Median survival for the entire cohort was 20.8 (range: 15.3-26.3) months. Age (P=0.020), gender (P=0.007), pack years (P=0.015), tumor-associated atelectasis (P=0.004) and histology (P=0.004) had a significant impact on overall survival and were scored with one point each. Twelve, 59 and 28 patients were defined to have a low (0-1 points), intermediate (2-3 points) and high-risk (4-5 points) score. Median survival, 1-, 2- and 3-year survival rates were not reached, 100%, 83% and 67% in the low, 22.9 months, 80%, 47% and 24% intermediate and 13.7 months, 57%, 25% and 18% high-risk patients, respectively (P<0.001). Median survival was not reached in prospective cohort; analysis has revealed a trend for the 1-year survival rates with 100% for the low, 93% intermediate and 69% high-risk patients (P=0.100). CONCLUSIONS: The score demonstrated remarkable survival differences in inoperable stage III NSCLC patients with good performance status receiving multimodal therapy.
RESUMEN
PURPOSE: To identify prognostic factors and create a survival score to facilitate individualized care of patients with metastatic spinal cord compression (MSCC) from small-cell lung cancer (SCLC). PATIENTS AND METHODS: Radiation regimen plus 9 factors were retrospectively evaluated in 120 patients irradiated for MSCC from SCLC for overall response, improvement of motor deficits, postradiotherapy ambulatory status, local control of MSCC, and overall survival (OS). Factors included age, interval diagnosis of SCLC to radiotherapy (RT) of MSCC, visceral metastases, further bone metastases, gender, time developing motor deficits, pre-RT ambulatory status, number of affected vertebrae, and Eastern Cooperative Oncology Group performance status (ECOG PS). RESULTS: Improvement of motor deficits showed significant associations with ECOG PS 1-2 (P = .018); time developing motor deficits achieved borderline significance (P = .059). Post-RT ambulatory status was significantly associated with slower development of motor dysfunction (P = .003), ambulatory status (P < .001), and ECOG PS 1-2 (P < .001). No factor was significantly associated with overall response and local control. On multivariate analysis, OS was significantly associated with interval from SCLC diagnosis to RT of MSCC (P = .004), visceral metastases (P < .001), ambulatory status (P = .002), and ECOG PS (P = .002). For the survival score, 6-month OS rates related to each of these factors were divided by 10. Patient scores were obtained by adding these factors' scores. Three groups were defined (5, 7-13, and 15-17 points) with 6-month OS rates of 0, 18%, and 77%, respectively (P < .001). CONCLUSION: Predictors of various outcomes were identified and a survival score was created that can support physicians aiming to create personalized treatments to patients with MSCC from SCLC.

BACKGROUND/AIM: Personalization of the treatment of brain metastases considering patient's overall survival (OS) prognosis is gaining importance. This study was conducted to develop an OS score particularly for patients receiving local therapies for single brain metastasis from gynecological malignancies. PATIENTS AND METHODS: In 11 patients, the following factors were retrospectively analyzed for associations with OS: Age, Karnofsky performance score (KPS), tumor type, extra-cranial metastatic sites, and time from diagnosis of gynecological malignancy to treatment of brain metastasis. Factors showing at least a strong trend were used for the score. RESULTS: A KPS of 80-90% resulted in a significantly better OS than a KPS of 50-70% (p=0.008). Absence of extra-cranial metastases showed a strong trend (p=0.052). For the score, the following points were used: KPS 50-70%=0, KPS 80-90%=1, presence of extra-cranial metastatic sites=0, absence=1. Patients' scores were 0, 1 or 2 points. OS rates at both 6 and 12 months were 0%, 67% and 100%, respectively (p=0.020). CONCLUSION: This specific score can be used to estimate OS in patients receiving local therapies for single brain metastasis from gynecological malignancies and personalize their care.

OBJECTIVE: To review published nomograms that predict endpoints such as overall survival (OS) or risk of intracranial relapse in patients with brain metastases from solid tumors. METHODS: The methods and results of nomogram studies identified by a systematic search were extracted and compared, stratified by endpoint predicted by the respective nomograms. In particular, validation strategies (external/internal), concordance indices (cut-off 0.75) and comparisons to older models were analyzed. RESULTS: Six publications reported on prediction of OS. Most of these analyses focused on one particular primary tumor site, e.g., breast cancer or hepatocellular carcinoma, while the largest study included different primary tumor sites. The median number of patients was 244. Three of six studies included external validation cohorts. With few exceptions, concordance indices <0.75 were reported. In all studies reporting this endpoint, the nomogram outperformed older prognostic scores. Two nomograms focused on development of new brain metastases after radiosurgery (one externally validated), one on survival free from salvage whole brain radiotherapy (WBRT) after radiosurgery, and one on neurologic and non-neurologic death in patients receiving radiosurgery after WBRT failure. All concordance indices of these 4 nomograms were <0.70. CONCLUSION: Taking into account concordance indices and comparisons to older prognostic models, the most promising, externally validated nomograms are the breast cancer and the non-small cell lung cancer nomogram predicting OS, and the distant brain failure after radiosurgery nomogram. Additional validation studies as well as continuous monitoring of the models' performance appear necessary to ensure their clinical applicability in the present era of rapidly changing treatment paradigms.

BACKGROUND/AIM: Prognoses of patients with metastatic epidural spinal cord compression (MESCC) from urothelial carcinoma of the bladder are generally poor. This study aimed to identify prognostic factors that can facilitate personalized care of these patients. PATIENTS AND METHODS: In 46 patients, 10 factors were evaluated for overall response (OR), post-radiotherapy (RT) ambulatory status, local control of MESCC and overall survival (OS). Independent predictors of OS were incorporated in a scoring system. RESULTS: Being ambulatory post-RT was associated with pre-RT ambulatory status (p<0.001) and better performance score (p<0.001). No factor was significantly associated with OR and local control. On multivariate analyses, lack of visceral metastases (p=0.002), being ambulatory pre-RT (p=0.001) and performance score 1-2 (p=0.004) were associated with improved OS. Based on these factors, there were three distinct prognostic groups with 0, 1-2 and 3 points and median OS times of 2, 4 and 11.5 months, respectively. CONCLUSION: Prognostic factors were identified and a new survival score was created that will help physicians aiming to personalize treatment for patients with MESCC from urothelial carcinoma of the bladder.
