Spain's Rising Melanoma Threat: A Comprehensive 30-Year Analysis (1990-2019).

AIM: This study aims to elucidate the factors driving melanoma incidence trends in Spain by analyzing the GBD-2019 dataset (1990-2019) and investigating the age-specific, birth cohort, and period effects on incidence rates. MATERIALS AND METHODS: This study analyzed melanoma incidence trends in Spain from 1990 to 2019 using an ecological design. Data were sourced from the Global Burden of Disease Study 2019 and Spain's National Statistics Institute. Age-standardized incidence rates (ASIRs) were calculated using joinpoint regression analysis, and age-period-cohort (A-P-C) modeling was employed to assess the effects of age, time period, and birth cohort on incidence rates. RESULTS: Between 1990 and 2019, an estimated 147,823 melanoma cases were diagnosed in Spain. The ASIRs showed a steady increase for both sexes, with slightly higher rates observed in men. Both men (average annual percentage change (AAPC): 2.8%) and women (AAPC: 2.4%) showed a steady increase in the ASIR over the period. Joinpoint analysis revealed distinct periods of incidence rate changes, with significant upward trends in earlier years followed by stabilization in recent years. Incidence rates increased steadily with age, with the highest rates in the 80-84 age group. Women tended to have slightly higher rates in younger age groups, while men had higher rates in older age groups. Both men and women experienced a steady increase in relative risk of melanoma throughout the 30-year study period, with significant upward trends across birth cohorts. CONCLUSIONS: Despite limitations, this study provides valuable insights into factors influencing melanoma incidence in Spain. By understanding age, period, and cohort effects, effective prevention strategies can be developed to reduce melanoma incidence.

Age, period and cohort effects on gastric cancer mortality in Spain, 1980-2021.

BACKGROUND: this study aimed to evaluate the effects of age, time period and cohort (A-P-C) on gastric cancer (GC) mortality in Spain from 1980 to 2021. METHODS: an ecological trend study was performed (with aggregated data obtained from the Spanish National Statistics Institute (INE). Joinpoint regression software was used to estimate rates by sex and age group (< 35, 35-64, > 64 years) and mortality trends. The National Cancer Institute A-P-C tools were used to assess the effects of age, time of death and birth cohort. RESULTS: GC mortality rates in Spain decreased significantly in both sexes. In the under-35 age group, rates were stable after an initial significant decline. In the 35-64 age group, the decline was more pronounced in males than in females. In the 65+ age group, rates fell significantly for both sexes, but more so for females than for males. The net drift and local drift also showed significant decreases across all age groups from 24 years onwards. GC mortality rates increased with age and decreased with calendar time and successive birth cohorts, regardless of sex. The ratio of age-specific rates between males and females increased with age, and birth cohort relative risk estimates followed a steady downward trend until the mid-1970s, after which the decline stabilized. The relative risk decreased for both sexes, with a more pronounced decrease in males. CONCLUSION: GC mortality rates in Spain have been decreasing over time and across successive birth cohorts, with a stabilizing trend observed for those under 35 years of age.

Epidemiology of Lung Cancer Mortality in Spain: Updated Information (1982-2021) and Predictions up to 2046.

BACKGROUND: Patterns of lung cancer (LC) mortality are important for planning health services and resource management. OBJECTIVES: We aimed to provide updated information (1982-2021) and project (LC) mortality rates in Spain (2022-2046). METHOD: We analysed data from the Spanish National Statistics Institute about mortality in LC (1982-2021), and we made predictions for the period 2022-2046. RESULTS: In 2021, a total of 22,413 people died of LC, and for the period 2042-2046, the projected annual average was 25,549 deaths. In males, age-standardised mortality rates (ASMR) (overall) after an initial period of increase (1982-1996, 2.2%) declined until 2021 (-1.4% per year), and this decline is expected to continue in the future (-1.9% per year during the period 2022-2046), although the projected decline is slightly higher (-2.0% during the period 2022-2046). In men, ASMR (all ages) after an initial period of increase (1982-1996, 2.2%) declined until 2021 (-1.4% per year), and this decline is expected to continue in the future during the period 2022-2046. In women, both the overall and truncated rates (35-64) increase during the period 1982-2021 (4.1% and 6.0% per year, respectively), and projected rates showed that both will decrease during the period 2022-2046, although more markedly in the truncated rates (-1.9% per year) than in the overall rates (-0.5% per year). CONCLUSIONS: Our projections show the magnitude of a steady upward trend in LC mortality among women in Spain that appears to be beginning to reverse from the current decade (similar to that observed for incidence).

Myelodysplastic syndromes mortality in Spain: a comprehensive age-period-cohort and joinpoint analysis.

OBJECTIVE: The present study aims to assess the mortality trends in myelodysplastic syndromes (MDS) in Spain from 1980 to 2021. METHODS: Deaths and mid-year population data were collected from the National Institute of Statistics. We estimated age-standardised mortality rates (ASMRs) per 100,000 person-years for all ages and ages 35-64. Joinpoint regression identified significant changes in mortality trends. The independent effects of age, period and birth cohort on MDS mortality were also examined. RESULTS: MDS-related deaths gradually increased from 36 in 1980 to 1118 in 2021, with an overall increase of 6.6% in age-standardised mortality rates (ASMRs) for both men and women. Joinpoint analysis identified four periods for both men and women: 1980-1987 (stable rates), 1987-1990 (sharp increase), 1990-1999 (slower increase) and 1999-2021 (stable rates). ASMRs (35-64 years) increased by 2.5% over the study period, with a turning point identified in 1996 when rates decreased. Mortality from MDS increases with age and is higher in men. The cohort's relative risk increased until the mid-1950s and then stabilised, whilst the period relative risk increased between 1982 and 1996 and then stabilised. CONCLUSION: The results of this study indicate a progressive increase in MDS-related deaths in Spain between 1980 and 2021. Notably, this increase was more pronounced in men than in women. Analysis of birth cohort trends revealed shifts in MDS risk, characterised by an increase until the mid-twentieth century, followed by a stabilisation. Using joinpoint analysis, four distinct periods were identified, shedding light on the changing patterns of mortality over time. These findings help to shape future research directions and inform public health strategies. They also provide optimism for advances in MDS treatment and potential reductions in mortality.

Clustering of systemic lupus erythematosus mortality in southwestern Spain.

OBJECTIVE: To analyse time trends in systemic lupus erythematosus (SLE) mortality and explore possible provincial clustering of SLE mortality in Spain (2001-2020). METHODS: We conducted an ecological study using deaths registered in SLE at the Spanish National Institute of Statistics between 2001 and 2020. Jointpoint regression models have been used to evaluate temporal trends. To analyse the spatial pattern of SLE mortality in men and women in Spain, crude rates, age-standardised mortality rates (ASMRs), smooth relative risk (RR) and posterior probabilities (PP) for RR greater than one for the period 2001-2020 were calculated. The Global Moran I index was used to assess the existence of global spatial autocorrelation. Local indicators of spatial association (LISA) and Kulldorff's spatial scan statistic were used to identify clusters. RESULTS: Over the 20 years analyzed in this study, the SLE average ASMR for the period was 2.7 for women and 0.7 for men, with a sex ratio (female/male) of 3.8. In men, no province showed a RR>1. Conversely, in women, eight provinces showed values of RR> 1 with a PP greater than 0.8 (Seville, Cadiz, Huelva and Murcia in the south, Barcelona, Zaragoza, Huesca and Leon in the north). In men, neither of the two methods detected a clustering of provinces. However, in women, both methods identified a cluster of provinces located in the southwest of the country (Huelva, Cádiz, Seville and Malaga) as a cluster with significant excess mortality. In the second cluster (centred on the province of Huelva) obtained with the Kulldorff method, two more provinces were added (Badajoz and Cordoba, also located in the southwest). CONCLUSIONS: We detected a cluster of provinces with an excess risk of female SLE mortality in the southwest of Spain.

Age-period-cohort effect on lung cancer mortality in Spain, 1982-2021.

BACKGROUND: The aim of the study is to provide up-to-date information and evaluate the age-period-cohort effects of age-period cohorts on lung cancer (LC) mortality in Spain for the period 1982 to 2021. METHODS: We analysed deaths by LC and population for the period 1982-2021, available from the Spanish National Institute of Statistics. The LC corresponds to code 162 and codes C33 and C34 of the 9th and 10th editions of the International Classification of Diseases, respectively. Age-period-cohort (A-P-C) modelling was applied to compute the net drift, local drift, longitudinal age curve, and rate ratios (RR) of each period and cohort. A-P-C analysis was performed using the A-P-C Web Tool provided by the National Cancer Institute of the United States. RESULTS: Estimated relative risk in the male birth cohorts has followed a steady downward trend in all cohorts born since 1922, showing an initial period (1922-1947) of slight decline, followed by a more marked decrease in the cohorts born during the period 1947-1977. In the younger cohorts (1977-1997), the decline appears to have stabilised. In women, a strong cohort effect is observed. In those born after the Spanish Civil War (1936 to 1939), the risk increased until it peaked in the 1960s, after which it started to decrease with the same intensity. Period RR in men decreased from 1987 to 1991 (1.1) to 2017-2021 (0.6), while period RR in women increased during this time (from 0.8 to 1.6). CONCLUSIONS: The cohort effect observed in women born after the Civil War suggests that the onset of the LC epidemic may have been due to a higher prevalence of women smokers in these cohorts. However, the trend observed in the younger cohorts suggests a possible slowing-down in the increase in mortality risk in the following years.

Chronic obstructive pulmonary disease mortality trends in Spain, 1980-2020.

OBJECTIVES: In Spain, there has been a recent increase in the mortality rate for chronic obstructive pulmonary disease (COPD) in younger women. This study aimed to analyze trends in the COPD mortality rate in Spain from 1980 to 2020, evaluating any differences between genders and age groups. METHODS: Death certificates and mid-year population data were obtained from the Spanish National Institute of Statistics. For both genders, age group-specific and standardized (overall and truncated) rates were calculated by the direct method using the world standard population. The data were analyzed using the joinpoint regression method. RESULTS: In both men and women, the number of COPD deaths increased from 1980 to 1999 (average annual increase of 7% in men and 4% in women), while from 1999 onwards, deaths decreased by -1.0% per year in both genders. In women, there was a significant final period of increase in the 55-59 to 70-74 age groups and a slowing of the decline in the over 75 age group. Additionally, an increase in mortality for the truncated rates was observed for women between 2006 and 2020. In men under 70 years of age, there was an initial period in which death rates remained stable or significantly increased, followed by a period in which they decreased significantly. CONCLUSIONS: Our study shows age and gender differences in COPD mortality trends in Spain. Although the data show a downward trend, we have identified a worrying increase in the truncated rates in women for the last few years.

Magnetic resonance imaging in patients with cardiac implantable electronic devices: A prospective study.

BACKGROUND: The number of patients with cardiac implantable electronic devices in whom magnetic resonance imaging (MRI) is indicated is constantly increasing. The potential risk of electromagnetic interference has limited its use and it is still contraindicated by the Food and Drug Administration in some cases. The aim of this study is to evaluate the safety and efficacy of MRI in these patients. METHODS: A prospective registry comprising patients with a pacemaker (PM) or implantable cardioverter-defibrillator (ICD), MRI-conditional or not, who were candidates for MRI (at 1.5 T) with no suitable alternative diagnostic technique. All devices were programmed before the procedure and patients were monitored throughout the test. Clinical, electrical, and technical parameters were evaluated before and after MRI. RESULTS: 147 MRI examinations (132 PM and 15 ICD) were performed. There were no clinical events or significant differences in the electrical parameters of the leads after MRI. A variation in the impedance of the ventricular leads was detected, although the difference was not clinically relevant. In one patient with a PM, a failure in release of the safety impulse was detected in the auto-threshold test, although the threshold was correctly determined. In 11 of the 17 thoracic MRIs, image artifacts were detected, preventing the diagnosis in two of them. CONCLUSIONS: In patients with cardiac implantable electronic devices, MRIs performed under a specific protocol has been shown to be safe in the short term even in the thoracic region, as well as interpretable in most cases.

The Beginning of the Trend Change in Lung Cancer Mortality Trends in Spain, 1980-2018 / El comienzo del cambio de tendencia en las tasas de mortalidad por cáncer de pulmón en España, 1980-2018

BACKGROUND: Recently, some countries have shown stable trends in lung cancer death rates among women not yet described for Spain. We propose to update lung cancer mortality rates in Spain during the period of 1980-2018 by sex and region. METHODS: We used lung cancer mortality (International Classification of Diseases code 162 for the 9th edition, and codes C33 and C34 for 10th edition) and population data from the Spanish National Statistics Institute for the period 1980-2018. Age-standardised mortality rates (ASMRs), all ages and 30-64 years, by region and sex were assessed through joinpoint regression. RESULTS: During the study period lung cancer ASMRs (all ages) in men decreased -0.4% per annum and increased by 3.1% in women. Recently, ASMR (30-64 years) accelerated its decrease (1992-2007; −0.7 and 2007-2018; −3.5%) in men and slowed its increase (1990-2012; 5.7% and 2012-2018; 1.4%) in women. In men, joinpoint analysis detected an initial period in all Autonomous Communities (ACs) in which the rates significantly increased, followed by a second period in which the rates decreased significantly (12 ACs) or remained stable (4 ACs) since the late 1980s or early 1990s. In women, upward trends in ASMRs (all ages) were observed for the whole period in all the ACs. In 13 ACs, an initial period was detected with joinpoint in which the rates remained stable or significantly decreased, followed by a second period in which the rates increased significantly since the late 1980s or early 1990s. CONCLUSIONS: Our study shows gender differences in lung cancer mortality trends in Spain. These differences may be explained by the increased use of tobacco among women and the decreased use among men

ANTECEDENTES: Recientemente, algunos países han mostrado tendencias estables en las tasas de mortalidad por cáncer de pulmón entre las mujeres que aún no se han descrito para España. Proponemos actualizar las tasas de mortalidad por cáncer de pulmón en España durante el período 1980-2018 por sexo y región. MÉTODOS: Utilizamos la mortalidad por cáncer de pulmón (código 162 de la Clasificación Internacional de Enfermedades según la novena edición, y los códigos C33 y C34 según la décima edición) y los datos poblacionales del Instituto Nacional de Estadística de España para el período 1980-2018. Las tasas específicas de mortalidad por edad (TEME), para todas las edades y entre los 30 y 64 años, por región y sexo, se evaluaron mediante el análisis de regresión por segmentos. RESULTADOS: Durante el período de estudio, la TEME (todas las edades) de cáncer de pulmón disminuyó un −0,4% por año en hombres y aumentó un 3,1% en mujeres. Recientemente, la TEME (30-64 años) aceleró su descenso (1992-2007: −0,7% y 2007-2018: −3,5%) en los hombres y desaceleró su aumento (1990-2012: 5,7% y 2012-2018: 1,4%) en las mujeres. En los hombres, el análisis de regresión por segmentos detectó un período inicial en todas las comunidades autónomas (CA) en el que las tasas aumentaron significativamente, seguido de un segundo período en el que las tasas disminuyeron significativamente (12 CA) o se mantuvieron estables (4 CA) desde finales de la década de los ochenta o principios de los noventa. En las mujeres, las tendencias al alza en la TEME (todas las edades) se observaron durante todo el período en todas las CA. En 13 CA, se detectó con el análisis de regresión un período inicial en el que las tasas se mantuvieron estables o disminuyeron significativamente, seguido de un segundo período en el que las tasas aumentaron significativamente desde finales de los años ochenta o principios de los noventa. CONCLUSIONES: Nuestro estudio muestra diferencias de género en las tendencias de mortalidad por cáncer de pulmón en España. Estas diferencias pueden explicarse por el aumento del uso de tabaco en las mujeres y la disminución del uso entre los hombres

Is the pace of decline in cardiovascular mortality decelerating in Spain?

INTRODUCTION AND OBJECTIVES: To update the information on mortality from cardiovascular diseases and assess recent trends in Spain. METHODS: Deaths from cardiovascular diseases (codes I20-I25, I50, I05-I09, I00-I02, I26-I49, I51, I52, I60-I69, I10-I15, and I70-I79 of the 10th revision of the International Classification of Diseases and Causes of Death) were obtained from the National Statistics Institute. Trends were analyzed using Joinpoint regression models. The results revealed the years (periods) composing each trend, as well as the annual percent change for each of them. The direction and magnitude of recent trends (last available 5-year period) were assessed by using the average annual percent change. RESULTS: The decline in mortality rates from cardiovascular diseases slowed from -3.7% and -4.0% in 1999-2013 to -1.7% and -2.2% since 2013 in men and women, respectively. During the study period (1999-2018) all the analyzed causes decreased significantly. Nevertheless, recent trends differed according to age, sex, and the cause analyzed. Truncated rates (35-64 years) slowed (cardiovascular disease and stroke in men and ischemic heart disease in both sexes), stabilized (cardiovascular disease, stroke, and other heart diseases in women, and blood vessel disease in men), or increased (other diseases of the heart in men and diseases of the blood vessels in women). CONCLUSIONS: In Spain, as in other countries, the reduction in mortality rates from cardiovascular diseases slowed (overall rates for both sexes and truncated in men) or stabilized (truncated rates in women) from 2014 to 2018.

The Beginning of the Trend Change in Lung Cancer Mortality Trends in Spain, 1980-2018.

BACKGROUND: Recently, some countries have shown stable trends in lung cancer death rates among women not yet described for Spain. We propose to update lung cancer mortality rates in Spain during the period of 1980-2018 by sex and region. METHODS: We used lung cancer mortality (International Classification of Diseases code 162 for the 9th edition, and codes C33 and C34 for 10th edition) and population data from the Spanish National Statistics Institute for the period 1980-2018. Age-standardised mortality rates (ASMRs), all ages and 30-64 years, by region and sex were assessed through joinpoint regression. RESULTS: During the study period lung cancer ASMRs (all ages) in men decreased -0.4% per annum and increased by 3.1% in women. Recently, ASMR (30-64 years) accelerated its decrease (1992-2007; -0.7 and 2007-2018; -3.5%) in men and slowed its increase (1990-2012; 5.7% and 2012-2018; 1.4%) in women. In men, joinpoint analysis detected an initial period in all Autonomous Communities (ACs) in which the rates significantly increased, followed by a second period in which the rates decreased significantly (12 ACs) or remained stable (4 ACs) since the late 1980s or early 1990s. In women, upward trends in ASMRs (all ages) were observed for the whole period in all the ACs. In 13 ACs, an initial period was detected with joinpoint in which the rates remained stable or significantly decreased, followed by a second period in which the rates increased significantly since the late 1980s or early 1990s. CONCLUSIONS: Our study shows gender differences in lung cancer mortality trends in Spain. These differences may be explained by the increased use of tobacco among women and the decreased use among men.

Regional differences in colorectal cancer mortality trends, Spain (1980-2018).

INTRODUCTION: the aim of this study was to describe the trends of colorectal cancer (CRC) mortality by autonomous communities (ACs) and gender in Spain (1980-2018). METHODS: the age-standardized mortality rates (ASMRs) for CRC (per 100,000) were calculated by direct standardization, using the world standard population. Mortality trends were described by ACs using a joinpoint regression model in both sexes. The annual percent changes and average annual percentage of change were computed for trends using the joinpoint regression analysis. RESULTS: during the most recent five-year period (2014-2018), the rates decreased among both males and females and were more pronounced in males (-2.3 %) than in females (-1.1 %), although with differences by ACs. ASMRs decrease in both sexes in the Basque Country, Canary Islands, Catalonia, Castile and Leon, Andalusia, Balearic Islands, Madrid, Murcia and Valencia. Whereas in other ACs, it only increases in males (Navarre, Castile-La Mancha, Extremadura and La Rioja) or females (Aragon, Asturias and Galicia). CONCLUSION: this updated analysis of temporal patterns of CRC mortality in Spain from 1980-2018, divided by ACs and sex, shows gender differences in CRC mortality trends. Despite the favorable trends in both sexes, the gender gap is widening.

Tendencias divergentes en la mortalidad por suicidio según comunidad autónoma y sexo (1980-2016) / Divergent trends in suicide mortality by Autonomous Community and sex (1980-2016)

OBJETIVOS: Analizar los cambios en las tendencias de la mortalidad por suicidio según comunidad autónoma y sexo en España durante el período 1980-2016 utilizando modelos de regresión joinpoint. MÉTODOS: Los datos de mortalidad se obtuvieron del Instituto Nacional de Estadística. Para cada comunidad autónoma y sexo, se calcularon las tasas brutas y estandarizadas. El análisis de regresión joinpoint se utilizó para identificar los puntos más adecuados en los que se produjo un cambio estadísticamente significativo en la tendencia. RESULTADOS: El análisis joinpoint permite diferenciar comunidades en las que las tasas permanecen a lo largo de todo el periodo de estudio estables tanto en hombres (Cantabria, Castilla-La Mancha) como en mujeres (Canarias y Cantabria) y otras con un descenso continuado (Extremadura en hombres y mujeres y Castilla-La Mancha en mujeres). En aquellas comunidades en las que se observan cambios en la tendencia se aprecia, en casi todas ellas, un primer periodo de incremento en las tasas tanto en hombres como en mujeres. Las tendencias más recientes muestran divergencias entre las diferentes comunidades autónomas así, en los hombres, Andalucía, Canarias, Castilla-León, Comunidad Valenciana, Galicia, Murcia, País Vasco y La Rioja muestran tendencias descendentes significativas mientras que Cataluña y Madrid muestran incrementos significativos (2007-2016: 2,4% y 2010-2016: 18,7%, respectivamente). Algo similar se observa en las mujeres, para las que Andalucía, Castilla y León, Comunidad Valenciana, Galicia, Murcia, País Vasco y La Rioja muestran tendencias descendentes mientras que en Baleares, Cataluña y Madrid la tendencia es ascendente (2001-2016: 5,0%; 2006-2016: 4,2% y 2010-2016: 18,7% respectivamente). CONCLUSIONES: La mortalidad por suicidio varía ampliamente a nivel de comunidad autónoma, tanto en términos de nivel de mortalidad como de tendencias. Poco se sabe sobre los determinantes de las tendencias observadas y, por lo tanto, se necesitan más estudios

OBJECTIVES: To analyse the changes in mortality trends by suicide according to Autonomous Community and sex in Spain during the period 1980-2016 using joinpoint regression models. METHODS: Mortality data were obtained from the Instituo Nacional de Estadística. For each Spanish autonomous community and sex, crude and standardised rates were calculated. The joinpoint analysis was used to identify the best-fitting points where a statistically significant change in the trend occurred. RESULTS: The joinpoint analysis allows to differentiate areas in which the rates remain stable in men (Cantabria, Castilla-La Mancha) and women (Canary and Cantabria) throughout the study period and others with a continued decline (Extremadura in both men and women and Castilla-La Mancha in women). In those communities where changes in the trend are observed, in almost all of them, there is a first period of increase in rates in both men and women. The most recent trends show divergences between the different autonomous communities and, in men, Andalusia, the Canary Islands, Castilla-León, the Valencian Community, Galicia, Murcia, the Basque Country and La Rioja show significant downward trends, while Catalonia and Madrid show significant increases (2007-2016: 2.4% and 2010-2016: 18.7% respectively). Something similar is observed in women where Andalusia, Castilla y León, Valencian Community, Galicia, Murcia, País Vasco and La Rioja show downward trends while in the Balearic Islands, Catalonia and Madrid the trend is upward (2001-2016: 5.0%; 2006-2016: 4.2% and 2010-2016: 18.7% respectively). CONCLUSIONS: Suicide mortality varies widely among the Spanish autonomous communities, both in terms of mortality level and trends. Little is known about the determinants of observed trends and, therefore, more studies are needed

Suicide mortality in Spain (1984-2018): age-period-cohort analysis. / Mortalidad por suicidio en España (1984-2018): análisis edad-período-cohorte.

OBJECTIVE: To assess the effects of age, period and cohort suicide mortality trend in Spain (1984-2018). METHODS: Mortality and population data were obtained from the National Institute of Statistics. The analysis of the effect of age, period of death and birth cohort on the evolution of suicide mortality in the period 1984-2018 was performed using a web tool for age-period-cohort analysis provided by the Division of Cancer Epidemiology and Genetics of the National Cancer Institute of the USA. RESULTS: Rates increase with age (age effect) in both sexes. The period effect shows, in males, an increase over the period 1984-1998 followed by a significant decrease until 2018. In females, rates remain stable over the period 1987-2002, decrease during 2007-2012 (p < 0.05) and eventually stabilise. In both males and females, the risk decreases in each successive birth cohort between 1904 and 1939. Subsequently, the risks increase until the birth cohort of the period 1964-1974 after which the risk decreases for males and remains stable for females. CONCLUSION: A better understanding of the effects of the birth cohort could open new doors in suicide prevention.

Intravenous Thrombolysis Guided by Perfusion CT with Alteplase in >4.5 Hours from Stroke Onset.

INTRODUCTION: The benefit of intravenous thrombolysis (IVT) in wake-up stroke (WUS), stroke of unknown time of onset (SUKO), or when time exceeds 4.5 h from last-seen-normal (LSN) guided by CT perfusion (CTP) or MRI has been recently suggested. However, there is limited information of IVT in those patients in real-world studies. OBJECTIVE: Our aim was to evaluate safety and efficacy of IVT selected by CTP in patients with WUS, SUKO, or stroke of time onset beyond 4.5 h. MATERIAL AND METHODS: We studied a prospective cohort of patients who underwent IVT from January 2010 to December 2017. Two groups were defined: standard of care group (SC) included patients with time onset <4.5 h and CTP group included patients with WUS, SUKO, or onset beyond >4.5 h from LSN with penumbra area in CTP. We evaluated baseline characteristics, functional outcomes according to modified Rankin Scale (mRS) at discharge and at 90 days, and intracranial hemorrhages rates. RESULTS: 657 patients were studied: 604 (92%) were treated in the SC group and 53 (8%) in the CTP group. The mean NIHSS score was 9.8 in the CTP group versus 13 in the SC group (p = 0.001). Seventeen patients in the CTP group (32.1%) received bridging therapy with mechanical thrombectomy (MT). Last time seen well-to-needle time was 538 versus 155 min (p < 0.001). The incidence of symptomatic intracranial hemorrhage was equal in both groups (3.8 vs. 3.8%, p = 1). Good functional outcome (mRS < 2) was achieved in both groups (72 vs. 60.4%, p = 0.107). CONCLUSIONS: IVT in patients with WUS, SUKO, or stroke beyond >4.5 h from LSN, with salvageable brain tissue on CTP, seems to be safe and has similar functional outcomes at 90 days to the standard therapeutic window, even when combined with MT.
