Validation of the UK myeloma research alliance risk profile, a new clinical prediction model for outcome in patients with newly diagnosed multiple myeloma not eligible for autologous stem cell transplantation; a population-based study from the Danish national multiple myeloma registry.

In 2019 the UK Myeloma Research Alliance introduced the Myeloma Risk Profile (MRP) for prediction of outcome in patients with newly diagnosed multiple myeloma (MM), ineligible for autologous stem cell transplantation. To validate the MRP in a population-based setting we performed a study of the entire cohort of transplant ineligible MM patients above 65 years in the Danish National MM Registry. Our data confirmed the value of the MRP. In a cohort of 1,377 patients, the MRP score separated patients into three distinct risk-groups with an observed hazard ratio of 2.91 for early death in high-risk versus low-risk patients.

High World Heath Organization Performance Status Is Associated With Short- and Long-term Outcomes After Colorectal Cancer Surgery: A Nationwide Population-Based Study.

BACKGROUND: The value of performance status is widely used in medical oncology, but the association with surgical outcomes in colorectal cancer has not been described. OBJECTIVE: The aim of this study was to investigate the association between World Heath Organization performance status and 90-day mortality, 30-day mortality, complications, and overall survival after elective colorectal cancer surgery. DESIGN: The study was conducted as a nationwide population-based cohort study with prospectively collected data. SETTING: Data from 2014 through 2016 were provided by the Danish nationwide colorectal cancer database (Danish Colorectal Cancer Group). PATIENTS: All patients aged ≥18, who had elective surgery for colorectal cancer were included. MAIN OUTCOME MEASURES: Multiple logistic regressions were performed to investigate 90-day mortality, 30-day mortality, and complications. One-year mortality was determined by Cox regression, and overall survival was illustrated by Kaplan-Meier curves. RESULTS: A total of 10,279 patients had elective colorectal cancer surgery during the study period (6892 colonic and 3387 rectal). Thirty-four percent of the patients with colorectal cancer had a World Heath Organization performance status ≥1. The odds ratios of postoperative 90-day mortality in colon cancer for performance status 1, 2, and 3/4 compared with performance status 0 were 2.50 (95% CI, 1.67-3.73), 5.00 (95% CI, 3.19-7.86), and 17.34 (95% CI, 10.18-29.55). The odds ratios of postoperative 90-day mortality in rectal cancer for performance status 1, 2, and 3/4 were 3.90 (95% CI, 2.23-6.85), 9.25 (95% CI, 4.75-18.02), and 10.56 (95% CI, 4.07-27.41). Performance status was also associated with 30-day mortality, overall survival, and medical complications. LIMITATIONS: Only 1 year of follow-up was possible for all patients, and cancer-specific survival was not available. CONCLUSION: One of three patients has a performance status >0 and is associated with an increased risk of death, complications, and overall survival for both colonic and rectal cancers.

Functional status and survival in patients ≥85 years of age who have keratinocyte carcinoma: A retrospective cohort study.

BACKGROUND: Functional status assessment may help estimate which patients ≥85 years of age will benefit from surgical treatment for keratinocyte carcinoma (KC), but predictive value for short-term survival in this population has not been determined. OBJECTIVE: We sought to assess the predictive value of functional status for short-term survival in patients ≥85 years of age who have KC. METHODS: This was a retrospective cohort review of 238 patients ≥85 years of age who presented for the management of KC between 2010 and 2015. Functional status was assessed with the Karnofsky Performance Scale (KPS) and Katz Activities of Daily Living (ADL) index. Overall survival was determined. RESULTS: Lower functional status scores of KPS ≤40 and Katz ADL ≤4 were associated with 37% and 53% survival at 2 years, respectively. LIMITATIONS: Retrospective design and single-center study. CONCLUSION: In this study, KPS and Katz ADL predicted short-term survival. Patients with low functional status scores had significantly decreased survival at 2 years, with double the death rate of patients with high functional status. Functional status should be considered during shared decision-making for elderly individuals who are seeking treatment for KC.

Risk factors for the development of cutaneous melanoma after allogeneic hematopoietic cell transplantation.

BACKGROUND: Melanoma risk is increased after allogeneic hematopoietic cell transplantation (HCT), but specific risk factors are unknown. OBJECTIVE: Investigate risk factors for melanoma after allogeneic hematopoietic cell transplantation. METHODS: We conducted a nested case-control study of 140 melanoma cases and 557 controls (matched by age at HCT, sex, primary disease, survival time) through the Center for International Blood and Marrow Transplant Research. RESULTS: Melanoma risk was significantly increased among HCT survivors who received total body irradiation-based myeloablative conditioning (multivariable adjusted odds ratio [OR] = 1.77; 95% confidence interval [CI] = 1.00-3.15) or reduced-intensity conditioning containing melphalan (OR = 2.60; 95% CI = 1.13-6.02) or fludarabine (OR = 2.72; 95% CI = 1.02-7.30) versus busulfan-based myeloablative regimens; were diagnosed with acute graft-versus-host disease (GVHD) with stage 2+ skin involvement (OR = 1.92; 95% CI = 1.19-3.10), chronic GvHD without skin involvement (OR = 1.91; 95% CI = 1.03-3.57), or keratinocytic carcinoma (OR = 2.37; 95% CI = 1.16-4.83); and resided in areas with higher ambient ultraviolet radiation (ORtertile3 = 1.64; 95% CI = 1.01-2.67). LIMITATIONS: Data on individual-level ultraviolet radiation exposure and clinical data on melanoma characteristics were lacking. Additionally, misclassification of melanoma is possible as not all pathology reports were available for review. CONCLUSION: These results emphasize the importance of adherence to current surveillance guidelines (routine skin examination, photoprotection recommendations), particularly for HCT survivors at highest risk.

Inter-rater reliability in performance status assessment among healthcare professionals: an updated systematic review and meta-analysis.

INTRODUCTION: Survival prediction for patients with incurable malignancies is invaluable information during end-of-life discussions, as it helps the healthcare team to appropriately recommend treatment options and consider hospice enrolment. Assessment of performance status may differ between different healthcare professionals (HCPs), which could have implications in predicting prognosis. The aim of this systematic review and meta-analysis is to update a prior systematic review with recent articles, as well as conduct a meta-analysis to quantitatively compare performance status scores. METHODS: A literature search was carried out in Ovid MEDLINE, Embase, and Cochrane Central Register of Controlled Trials, from the earliest date until the first week of August 2019. Studies were included if they reported on (1) Karnofsky Performance Status (KPS), Eastern Cooperative Oncology Group (ECOG) Performance Status, and/or Palliative Performance Scale (PPS) and (2) assessment of performance status by multiple HCPs for the same patient sets. The concordance statistics (Kappa, Krippendorff's alpha, Kendall correlation, Spearman rank correlation, Pearson correlation) were extracted into a summary table for narrative review, and Pearson correlation coefficients were calculated for each study and meta-analyzed with a random effects analysis model. Analyses were conducted using Comprehensive Meta-Analysis (Version 3) by Biostat. RESULTS: Fourteen articles were included, with a cumulative sample size of 2808 patients. The Pearson correlation coefficient was 0.787 (95% CI: 0.661, 0.870) for KPS, 0.749 (95% CI: 0.716, 0.779) for PPS, and 0.705 (95% CI: 0.536, 0.819) for ECOG. Four studies compared different tools head-to-head; KPS was favored in three studies. The quality of evidence was moderate, as determined by the GRADE tool. CONCLUSIONS: The meta-analysis's Pearson correlation coefficient ranged from 0.705 to 0.787; there is notable correlation of performance status scores, with no one tool statistically superior to others. KPS is, however, descriptively better and favored in head-to-head trials. Future studies could now examine the accuracy of KPS assessment in prognostication and focus on model-building around KPS.

Patients with Alcoholic Liver Disease Have Worse Functional Status at Time of Liver Transplant Registration and Greater Waitlist and Post-transplant Mortality Which Is Compounded by Older Age.

BACKGROUND: Worse functional status correlates with increased mortality on the liver transplant (LT) waitlist. Whether functional status affects LT outcomes equally across cirrhosis etiologies is unclear. AIMS: We evaluate the impact of functional status on waitlist and post-LT mortality stratified by etiology and age. METHODS: Functional status among US adults from 2005 to 2017 United Network for Organ Sharing LT registry data was retrospectively evaluated using Karnofsky Performance Status Score (KPS-1 = functional status 80-100%, KPS-2 = 60-70%, KPS-3 = 40-50%, KPS-4 = 10-30%). Waitlist and post-LT survival were stratified by KPS and cirrhosis etiology, including alcoholic liver disease (ALD), nonalcoholic steatohepatitis (NASH), hepatitis C (HCV), and HCV/ALD, and evaluated using Kaplan-Meier and multivariate Cox proportional hazard models. RESULTS: Among 94,201 waitlist registrants (69.4% men, 39.5% HCV, 26.7% ALD, 23.2% NASH), ALD patients had worse functional status compared to HCV (KPS-4: 17.2% vs. 8.3%, p < 0.001). Worse functional status at time of waitlist registration was associated with higher 90-day waitlist mortality with the greatest effect in ALD (KPS-4 vs. KPS-1: ALD HR 2.16, 95% CI 1.83-2.55; HCV HR 2.17, 95% CI 1.87-2.51). Similar trends occurred in 5-year post-LT survival with ALD patients the most harmed. Compared to patients < 50 years, patients ≥ 65 years had increased waitlist mortality at 90-days if they had HCV or HCV/ALD, and 5-year post-LT mortality regardless of cirrhosis etiology with ALD patients most severely affected. CONCLUSIONS: In a retrospective cohort study of patients, US ALD patients had disparately worse functional status at time of LT waitlist registration. Worse functional status correlated with higher risk of waitlist and post-LT mortality, affecting ALD and HCV patients the most.

Symptom Expression in Patients with Advanced Cancer Admitted to an Acute Supportive/Palliative Care Unit With and Without Delirium.

AIM: The aim of this study was to investigate the relationship between delirium and symptom expression in patients with advanced cancer admitted to an acute supportive/palliative care unit (ASPCU). METHODS: A consecutive sample of patients with advanced cancer who were admitted to an ASPCU was prospectively assessed for a period of 10 months. The Edmonton Symptom Assessment Scale (ESAS) and the MDAS (Memorial Delirium Assessment Scale) were measured at admission (T0) and after 7 days of palliative care (T7). RESULTS: Two hundred forty-six patients had complete data regarding MDAS measurements, at either T0 and T7. Of these, 75 (30.5%) and 63 patients (25.6%) had delirium at T0 and after a week of palliative care (T7), with a decrease in the frequency of delirium of 4.9% (from 30.5% to 25.6%); that means that 16% of patients with delirium improved their cognitive status after initiation of palliative care. Intensities of pain, depression, poor well-being, and global ESAS were significantly higher in patients with delirium. Patients who did not have delirium at T0 but developed delirium during admission after 1 week of palliative care had a higher level of symptom expression for pain, weakness, nausea, anxiety, dyspnea, appetite, and consequently global ESAS. Patients who did not develop delirium at any time had a relevant decrease in intensity of all ESAS items after 1 week of palliative care. The decrease of symptom intensity was significant for pain, insomnia, appetite, poor well-being, and global ESAS in patients with delirium either at T0 and T7, although these differences were less relevant than those observed in patients without delirium. In patients with delirium at T0 who improved their cognitive function at T7 (no delirium), significant changes were found in most ESAS items. CONCLUSION: Symptom expression is amplified in patients with delirium, whereas patients without delirium may be more responsive to palliative treatments with a significant decrease in intensity of ESAS items. IMPLICATIONS FOR PRACTICE: Symptom expression is amplified in patients with cancer who have delirium, whereas patients without delirium may be more responsive to palliative treatments with a significant decrease in symptom intensity.

Prognostic factors of brain metastases from colorectal cancer.

BACKGROUND: For brain metastases from non-specific primary tumors, the most frequently used and validated clinical prognostic assessment tool is Karnofsky performance status (KPS). Given the lack of prognostic factors of brain metastases from colorectal cancer (CRC) other than KPS, this study aimed to identify new prognostic factors. METHODS: This retrospective cohort study was conducted at a tertiary care cancer center. Subjects were patients with brain metastases from CRC among all patients who received initial treatment for CRC at the National Cancer Center Hospital from 1997 to 2015 (n = 7147). Prognostic clinicopathological variables for overall survival (OS) were investigated. RESULTS: There were 68 consecutive patients with brain metastases from CRC, corresponding to 1.0% of all patients with CRC during the study period. Median survival time was 6.8 months. One-year and 3-year OS rates were 28.0 and 10.1%, respectively. Among the six covariates tested (age, KPS, presence of extracranial metastases, control of primary lesion, number of brain metastases, and history of chemotherapy), multivariate analysis revealed KPS (score ≥ 70), number of brain metastases (1-3), and no history of chemotherapy to be independent factors associated with better prognosis. CONCLUSIONS: In addition to KPS, the number of brain lesions and history of chemotherapy were independent prognostic factors for OS in patients with brain metastases from CRC. An awareness of these factors may help gastrointestinal surgeons make appropriate choices in the treatment of these patients.

Survival after stereotactic radiotherapy in patients with early-stage non-small cell lung cancer.

Introduction: Stereotactic radiotherapy (SBRT) is the treatment of choice for inoperable early stage non-small cell lung cancer (NSCLC). We report analyses of the influence of age on survival after SBRT. Methods and material: From 2005 to 2017, 544 previously un-irradiated patients with early stage NSCLC had SBRT. The data were analyzed in four age groups: A: -69 (176 pts), B: 70-74 (115 pts), C: 75-79 (131 pts) and D: 80 years or older (122 pts). Two SBRT dose regimes were used: 45 Gy/3F (N = 103) and 66 Gy/3F (N = 441). Results: All patients had a follow up (time to censoring, FU) of at least 16 months, the median FU being 48.0 months. The median age was 74.4 years. The overall survival (OS) was associated with age. The median OS was 50.7, 45.9, 45.4 and 33.0 months, and the 5-year OS was 45%, 32%, 33% and 18% in groups A, B, C and D, respectively. No difference was found between groups B and C, while OS in group A was significantly better than remaining groups, and the OS in group D significantly poorer. In multivariable analyses, OS was heavily influenced by age, Charlson's comorbidity index (CCI) and performance status (PS). For lung cancer-specific survival (LCSS), only increasing tumor diameter and PS were associated with poor survival. Conclusions: The OS was influenced by age, but the study suggests that a cut point of 75 year is inappropriate in evaluating the effect of old age on survival. Poor PS was associated with poor OS. CCI influenced OS, but not LCSS, which was only affected by PS and tumor size.

Poor-Performance Status Assessment of Patients with Non-small Cell Lung Cancer Remains Vague and Blurred in the Immunotherapy Era.

PURPOSE OF REVIEW: In the latest decade, the introduction of immune-checkpoint inhibitors (ICIs) has dramatically improved the prognosis of patients with NSCLC. First-line ICIs or chemo-ICI trials have demonstrated OS advantages but the accrual was limited to Eastern Cooperative Oncology Group (ECOG) performance status (PS)0-1 patients. ICI studies have for the vast majority excluded patients with poor performance status. PS 2 particularly is known as a negative prognostic factor for survival and a predictive factor of adverse events and poor response to treatments. Data on the activity of ICIs in PS2 patients are limited and come from heterogeneous meta-analyses and small phase II or expanded access trials. Often, terms such as "unfit" or "frail" ascertain the eligibility of patients to undergo cytotoxic chemotherapy, without specifying PS. RECENT FINDINGS: Other tools exist to aid in decision-making, and one simple, rapid, and validated screening test for frailty is the FRAIL scale consisting of 5 straightforward questions that can be self-administered and may represent an efficient and cost-effective way to screen large groups of patients for frailty. The Comprehensive Geriatric Assessment (CGA) is a widely used method to determine the medical, psychological, and functional capabilities of older patients. However, CGA is time-consuming and this could represent a real barrier to its adoption in clinical practice. For this reason, a quick screening tool, the G8 questionnaire, has been developed and demonstrated validity also in a younger population. A complementary tool to assess patients' frailty is Charlson comorbidity index (CCI) which has become the most widely used clinical index for a variety of disorders and cancers. Yet, none of these tools has been validated as predictive in ICI. In conclusion, solid data regarding the benefit of ICIs in ECOG PS2 NSCLC patients are currently lacking and the role of immunotherapy remains uncertain for PS2 patients. Prospective randomized trials addressing this question are warranted or ongoing. However, we are concerned that without a more extensive and objective assessment of patients' fitness and frailty by using and validating appropriate tools a clear answer may not come to light.

The Association of Performance Status and Disease Severity in Patients With Chronic Graft-vs-Host Disease.

OBJECTIVE: Determine the relationship between functional status and degree of specific organ involvement, physical performance, and subjective well-being chronic graft-vs-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation. DESIGN: Observational cohort. SETTING: Outpatient clinic. PARTICIPANTS: Adult patients (N=121) with cGVHD with 634 assessments. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Karnofsky Performance Status (KPS). Skin, fascia/joints, lungs, upper and lower extremity range of motion, liver, eye, mucosal, and gastrointestinal involvement were measured using the National Institutes of Health GVHD scale. Physical performance was assessed with the 2-minute walk test (2MWT) and hand grip strength. Subjective measures were the Patient Health Questionnaire 9 (PHQ-9) and Lee Symptom Burden (LSB) scale. RESULTS: Myofascial (P<.001) and lung (P=.001) involvement, 2MWT (P<.001), LSB (P<.001), and PHQ-9 (P=.03) had the largest associations with KPS with liver (P=.05) and hand grip strength (P<.001) more modest associations with KPS. CONCLUSIONS: Patients with cGVHD experience multifactorial impairment in function associated with potentially modifiable symptoms physiatrists have the expertise to address to enhance function. More research is needed to determine rehabilitation interventions to mitigate the impact of cGVHD on function.

Prospective study in bullous pemphigoid: association of high serum anti-BP180 IgG levels with increased mortality and reduced Karnofsky score.

BACKGROUND: Bullous pemphigoid (BP) is a subepidermal blistering disease characterized by autoantibodies against the two hemidesmosomal proteins, BP180 (type XVII collagen) and BP230. The multicentre prospective BLISTER (Bullous Pemphigoid Steroids and Tetracyclines) trial randomized 253 patients with BP to compare the benefits and harms between initial treatment with doxycycline or prednisolone. OBJECTIVES: To analyse distinct autoantibody profiles for the prediction of the disease course in a well-characterized cohort of BP sera. METHODS: One hundred and forty-three patients of the BLISTER trial consented to participate in this serological study. Sera taken at baseline were analysed by (i) indirect immunofluorescence, (ii) anti-BP180 NC16A (16th noncollagenous domain) and anti-BP230 enzyme-linked immunosorbent assay and (iii) immunoblotting with various substrates. Results were then linked with clinical parameters including age, Karnofsky score, number of blisters, related adverse events and mortality. RESULTS: Disease activity correlated with immunoglobulin (Ig)G anti-BP180 levels but not with levels of anti-BP230 IgG and anti-BP180 IgE. High levels of both anti-BP180 IgG and anti-BP230 IgG were associated with a low Karnofsky score. The presence of anti-BP230 IgG was more frequent in older patients. Those with higher total IgE serum levels suffered from fewer adverse events. Higher IgG anti-BP180 levels were associated with an increased 1-year mortality rate. CONCLUSIONS: Analysis of the autoantibody profile is not only of diagnostic relevance but may also be helpful in predicting the course of the disease.

Changes in physical functioning among men and women aged 50-79 years in Germany: an analysis of National Health Interview and Examination Surveys, 1997-1999 and 2008-2011.

BACKGROUND: This study examines changes in physical functioning among adults aged 50-79 years in Germany based on data from two German National Health Interview and Examination Surveys conducted in 1997-1999 (GNHIES98) and 2008-2011 (DEGS1). METHODS: Using cross-sectional data from the two surveys (GNHIES98, n = 2884 and DEGS1, n = 3732), we examined changes in self-reported physical functioning scores (Short Form-36 physical functioning subscale (SF-36 PF)) by sex and age groups (50-64 and 65-79 years). Covariables included educational level, living alone, nine chronic diseases, polypharmacy (≥5 prescribed medicines), body mass index, sports activity, smoking and alcohol consumption. Multimorbidity was defined as ≥2 chronic diseases. Multivariable models were fitted to examine consistency of changes in physical functioning among certain subgroups and to assess changes in mean SF-36 PF scores, adjusting for changes in covariables between surveys. RESULTS: Mean physical functioning increased among adults aged 50-79 years between surveys in unadjusted analyses, but this change was not as marked among men aged 65-79 years who experienced rising obesity (20.6 to 31.5%, p = 0.004) and diabetes (13.0 to 20.0%, p = 0.014). Prevalence of multimorbidity and polypharmacy use increased among men and women aged 65-79 years. In sex and age specific multivariable analyses, changes in physical functioning over time were consistent across subgroups. Gains in physical functioning were explained by improved education, lower body mass index and improved health-related behaviours (smoking, alcohol consumption, sports activity) in women, but less so among men. CONCLUSIONS: Physical functioning improved in Germany among adults aged 50-79 years. Improvements in the population 65-79 years were less evident among men than women, despite increases in multimorbidity prevalence among both sexes. Changes in health behaviours over time differed between sexes and help explain variations in physical functioning. Targeted health behaviour interventions are indicated from this study.

The influence of intraoperative resection control modalities on survival following gross total resection of glioblastoma.

The purpose of the present study is to analyze the impact of intraoperative resection control modalities on overall survival (OS) and progression-free survival (PFS) following gross total resection (GTR) of glioblastoma. We analyzed data of 76 glioblastoma patients (30f, mean age 57.4 ± 11.6 years) operated at our institution between 2009 and 2012. Patients were only included if GTR was achieved as judged by early postoperative high-field MRI. Intraoperative technical resection control modalities comprised intraoperative ultrasound (ioUS, n = 48), intraoperative low-field MRI (ioMRI, n = 22), and a control group without either modality (n = 11). The primary endpoint of our study was OS, and the secondary endpoint was PFS-both analyzed in Kaplan-Meier plots and Cox proportional hazards models. Median OS in all 76 glioblastoma patients after GTR was 20.4 months (95 % confidence interval (CI) 18.5-29.0)-median OS in patients where GTR was achieved using ioUS was prolonged (21.9 months) compared to those without ioUS usage (18.8 months). A multiple Cox model adjusting for age, preop Karnofsky performance status, tumor volume, and the use of 5-aminolevulinic acid showed a beneficial effect of ioUS use, and the estimated hazard ratio was 0.63 (95 % CI 0.31-1.2, p = 0.18) in favor of ioUS, however not reaching statistical significance. A similar effect was found for PFS (hazard ratio 0.59, p = 0.072). GTR of glioblastoma performed with ioUS guidance was associated with prolonged OS and PFS. IoUS should be compared to other resection control devices in larger patient cohorts.

Prognostic factors in patients treated with stereotactic image-guided robotic radiosurgery for brain metastases: a single-center retrospective analysis of 223 patients.

In this retrospective study, we evaluated the overall survival (OS) and local control (LC) of brain metastases (BM) in patients treated with stereotactic radiosurgery (SRS). The scope was to identify host, tumor, and treatment factors predictive of LC and survival and define implications for clinical decisions. A total of 223 patients with 360 BM from various histologies treated with SRS alone or associated with whole brain radiotherapy (WBRT) in our institution between July 1, 2008 and August 31, 2013 were retrospectively reviewed. Among other prognostic factors, we had also evaluated retrospectively Karnofsky performance status scores (KPS) and graded prognostic assessment (GPA). Overall survival (OS) and local control (LC) were the primary endpoints. Kaplan-Meier and Cox proportional hazards models were used to estimate OS and LC and identify factors predictive of survival and local control. The median duration of follow-up time was 9 months (range 0.4-51 months). Median overall survival of all patients was 11 months. The median local control was 38 months. No statistical difference in terms of survival or LC between patients treated with SRS alone or associated with WBRT was found. On multivariate analysis, KPS was the only statistically significant predictor of OS (hazard ratio [HR] 2.53, p = 0.006). On univariate analysis, KPS and GPA were significantly prognostic for survival. None of the host, tumor, or treatment factors analyzed in the univariate model factors were significantly associated with local failure.

Improved Mortality Prediction in Dialysis Patients Using Specific Clinical and Laboratory Data.

BACKGROUND: Risk prediction models can be used to inform patients undergoing renal replacement therapy about their survival chances. Easily available predictors such as registry data are most convenient, but their predictive value may be limited. We aimed to improve a simple prediction model based on registry data by incrementally adding sets of clinical and laboratory variables. METHODS: Our data set includes 1,835 Dutch patients from the Netherlands Cooperative Study on the Adequacy of Dialysis. The potential survival predictors were categorized on availability. The first category includes easily available clinical data. The second set includes laboratory values like albumin. The most laborious category contains glomerular filtration rate (GFR) and Kt/V. Missing values were substituted using multiple imputation. Within 1,225 patients, we recalibrated the registry model and subsequently added parameter sets using multivariate Cox regression analyses with backward selection. On the other 610 patients, calibration and discrimination (C-index, integrated discrimination improvement (IDI) index and net reclassification improvement (NRI) index) were assessed for all models. RESULTS: The recalibrated registry model showed adequate calibration and discrimination (C-index=0.724). Adding easily available parameters resulted in a model with 10 predictors, with similar calibration and improved discrimination (C-index=0.784). The IDI and NRI indices confirmed this, especially for short-term survival. Adding laboratory values resulted in an alternative model with similar discrimination (C-index=0.788), and only the NRI index showed minor improvement. Adding GFR and Kt/V as candidate predictors did not result in a different model. CONCLUSION: A simple model based on registry data was enhanced by adding easily available clinical parameters.

Quality of life assessed with EQ-5D in patients undergoing glioma surgery: what is the responsiveness and minimal clinically important difference?

PURPOSE: To evaluate the responsiveness of EQ-5D 3L in patients undergoing intracranial glioma surgery and estimate the minimal clinically important difference (MCID). MATERIALS AND METHODS: EQ-5D 3L index values from 164 patients who underwent glioma surgery in the period 2007-2012 were analysed. Responsiveness and MCID were estimated using a combination of distribution-based and anchor-based methods. Karnofsky performance status served as an anchor. RESULTS: Patients who improved functionally did not report significantly higher EQ-5D 3L scores post operatively with a standardized response mean (SRM) of 0.04 (p = 0.13). Patients who deteriorated functionally reported significantly lower EQ-5D 3L scores post operatively with a SRM of 0.72 (p < 0.001). With different approaches, we determined a range of MCID values from 0.13 to 0.15. CONCLUSIONS: EQ-5D 3L is responsive to changes when glioma patients are deteriorating functionally after surgery but not responsive when the patients are improving. The MCID values for EQ-5D 3L in glioma surgery seem higher than reported MCID values for other types of cancers.

Is performance status associated with symptom scores? A population-based longitudinal study among cancer outpatients.

BACKGROUND: Symptom scores and performance status are both important measures for patients with cancer. However, since performance status is not often part of routinely collected data, there is interest in exploring whether it can be calculated from symptom scores. METHODS: This was a population-based longitudinal study of cancer outpatients in Ontario, Canada in the year following their cancer diagnosis and among the subset of patients during the last year of their lives. RESULTS: In the first year after diagnosis, there was a significant relationship between performance status and fatigue and appetite; fatigue and well-being had a significant association with performance status in the last year of life. In both periods, the associations, although statistically significant, were not large enough to be clinically meaningful. CONCLUSION: Performance status is an important measurement that cannot be substituted or captured with symptom scores; it is important for healthcare providers to record performance scores on a regular basis.

Quality of life and performance status in patients with pancreatic and periampullary tumors.

BACKGROUND: To determine if pretreatment quality of life is associated with performance status in patients with pancreatic and periampullary tumors. METHODS: Eighty consecutive patients evaluated for surgical treatment of pancreatic or periampullary tumors completed the social functioning SF-36, a generic quality of life instrument. This instrument measures 8 domains of quality of life: physical functioning (PF), role-physical (RP), role-emotional, bodily pain, vitality, mental health, social functioning, and general health (GH). The best possible score is 100 and the worst possible score is 0. Each patient was then assigned a Karnofsky performance score (KPS), with the best possible score of 100 (normal, no complaints, no evidence of disease) and worst score of 0 (dead). Data recorded included age, gender, pathology, stage, resection, use of chemotherapy, and radiation therapy. Statistical analysis was done using single and multiple linear regression analysis, correlation coefficients (r) and coefficient of determination (r (2)). RESULTS: KPS was significantly associated with all domains of the SF-36 by single linear regression. By multiple linear regression, KPS was significantly associated with the PF domain (p < 0.001, r = 0.74), and nearly significantly associated with the RP (p = 0.07, r = 0.62) and GH (p = 0.06, r = 0.64) domains. This appears to be independent of tumor pathology and stage. CONCLUSION: The results imply that pretreatment quality of life and performance status are related concepts in patients with pancreatic and periampullary tumors. This is primarily true for the physical component of the SF-36. However, despite statistical significance, coefficients of determination (r (2) values) suggest that there are additional factors determining both quality of life and performance status in patients with pancreatic and periampullary tumors.

A systematic review of craniospinal irradiation for leptomeningeal disease: past, present, and future.

PURPOSE: Leptomeningeal disease (LMD) is a rare but deadly complication of cancer in which the disease spreads to the cerebrospinal fluid and seeds the meninges of the central nervous system (CNS). Craniospinal irradiation (CSI) involves treatment of the entire CNS subarachnoid space and is occasionally used as a last-resort palliative therapy for LMD. METHODS: This review examined literature describing the role of CSI for LMD from solid and hematologic malignancies in adults. A search for studies published until September 1, 2020 was conducted using PubMed database. RESULTS: A total of 262 unique articles were identified. Thirteen studies were included for analysis in which a total of 275 patients were treated with CSI for LMD. Median age at time of irradiation was 43 years, and most patients had KPS score of 70 and higher. The most common cancers resulting in LMD were acute lymphocytic leukemia, breast cancer, and acute myelogenous leukemia. Median CSI dose was 30 Gy and 18% of patients were treated with proton radiation. 52% of patients had stable-to-improved neurologic symptoms. Median overall survival for the entire cohort was 5.3 months. Patients treated with marrow-sparing proton radiation had median OS of 8 months. The most common treatment toxicities were hematologic and gastrointestinal events. CONCLUSIONS: Despite advances in systemic and radiation therapies, LMD remains a devastating end-stage complication of some malignancies. Treatment-related toxicities can be a significant barrier to CSI delivery. In select patients with LMD, marrow-sparing proton CSI may provide safer palliation of symptoms and prolong survival.
