Changes in the network structure of well-being components in adolescents in the school context: A 2-year longitudinal study

Disentangling the connections between subjective and psychological well-being may help practitioners identify effective targets of intervention to promote mental health in school settings. Based on theoretical foundations of well-being, the present study utilized psychometric network analysis to explore prospective associations between the subjective and psychological well-being of adolescents over 2 years. To this end, a cross-sectional network was estimated at Time 1 (n = 560) and Time 2 (n = 281), followed by a longitudinal network incorporating individual changes across time points in each component (n = 235). The networks included different indicators of subjective (e.g., life satisfaction, positive affect, negative affect) and psychological well-being measured by means of self-reported questionnaires. The results revealed direct connections between indicators of subjective and psychological well-being over time. Positive affect, especially feeling happy and satisfied, exhibited most of these connections. Only one negative longitudinal association emerged, which involved negative affect (e.g., feeling worried) and psychological well-being. The suitability of the network approach to represent the structure of subjective and psychological well-being can be used to widen research on adolescents' well-being. Considering the longitudinal associations identified, the present study makes an exploratory hypothesis to propose specific connectors between subjective and psychological well-being as potential targets for interventions aimed at promoting adolescents' mental health.

The relationship between subjective well-being and food: a qualitative study based on children's perspectives

PURPOSE

Despite the lack of consensus regarding which life satisfaction domains should be included in the study of children's subjective well-being (SWB), some domains are frequently considered, such as satisfaction with health. However, some others, such as satisfaction with food, are barely taken into account, despite the impact eating habits have on children's health and well-being. We adopt a qualitative approach to explore the role food plays in children's SWB, providing for a more in-depth analysis of children's perceptions and evaluations on a still insufficiently known domain of life satisfaction.

METHOD

Sixteen discussion groups were held with 112 Spanish students (10-12 years old) from six schools. The transcripts were analy sed and themes reflecting the key concepts were defined using reflexive thematic analysis.

RESULTS

Five themes emerged from the children's discourses on the relationship between food and SWB: health, pleasure, emotions, commensality-i.e., eating together-and food-empowerment-thus offering new insights from children's perspectives.

CONCLUSION

Almost all of the participants established a relationship between their SWB and their eating behaviour, meaning that, within the challenges facing public health, SWB must be taken into account when promoting healthy eating programmes for children. Also, group discussion is found to be a very powerful tool for exploring topics with subjective connotations among child populations.

Sibling Bullying, School Bullying, and Children's Subjective Well-Being Before and During the COVID-19 Pandemic in Indonesia

The aims of this study are threefold. The first aim is to examine the prevalence of sibling and school bullying before and during the COVID-19 pandemic in Indonesia. The second aim is to investigate the subjective well-being (SWB) of children who were bullied or never bullied before and during COVID-19. The third aim is to investigate factors associated with sibling and school bullying before and during the COVID-19 pandemic. This study uses two separate cross-sectional datasets from the Children's Worlds survey in Indonesia. Data in Study 1 were collected in October 2017 (N = 12,794; 48.2% boys; 51.8% girls, mean age = 10.56), while data in Study 2 were collected from July to September 2021 (N = 2,222; 46.1% boys; 53.9% girls; mean age = 10.77). Five items were used to measure sibling and school bullying. The five-item version of the Children's Worlds Subjective Well-Being Scale (CW-SWBS5) was used as the SWB indicator. Three groups of independent variables (family, friends and school climate) were analysed using linear regression to investigate the contribution of each variable to sibling and school bullying. Results show that the prevalence of sibling bullying during the COVID-19 pandemic is higher than before the pandemic, while the frequency of school bullying incidents during COVID-19 is lower than before COVID-19. SWB scores of children during COVID-19 are lower than SWB scores of children before the COVID-19 pandemic, both for bullied or never-bullied children. The fact that children report that parents listen to them and take what they say into account is positively associated with a lower frequency of being bullied at home before and during COVID-19 and being bullied at school only during the pandemic. Although samples are not strictly comparable, the SWB indicators used in both studies showed sensitivity to the changes in children's lives in previous studies. Therefore, the SWB indicators are supposed to be sensitive to changes associated with children's new everyday life COVID-19 has implied.

Satisfaction with the Neighborhood of Israeli and Chilean Children and its Effects on their Subjective Well-being

A study of subjective well-being in 4,942 children (49% girls) aged 10 and 12 living in Israel and Chile is presented. The association between perceptions of the neighborhood and subjective well-being (SWB) was analyzed based on a mediation model using satisfaction with the neighborhood as a mediating variable. The overall results showed high average SWB scores for both countries as well as high levels of satisfaction with the neighborhoods where they live. Differences between the countries were observed for the age groups. The SWB of Chilean children decreased with age, while a decrease was not detected for the Israeli children. The mediation model had excellent fit for the age groups and countries, and the satisfaction with the neighborhood variable presents a partial mediation effect between neighborhood variables and SWB. Satisfaction with the neighborhood displayed a greater effect on the SWB of the older children than the younger ones. Gender showed significant effects on SWB only in Chile. The results are discussed, analyzing the similarities and differences between both countries and providing new evidence for the study of SWB at the international level. Questions for a more specific analysis of SWB within each country are suggested.

Subjective well-being of children and adolescents during the COVID-19 pandemic in Indonesia: two data collections

This paper examines the subjective well-being (SWB) of children and adolescents (10‒18 years old) during the COVID-19 pandemic in Indonesia for two periods (May to July 2020 and March to May 2021), using cross-sectional data from two distinct samples of N = 1,011 (M age = 14.61) and N = 1,640 (M age = 14.86), respectively. Its aims are twofold: (1) to examine the state of SWB among Indonesian children, including its cognitive component (measured using the CW-SWBS), positive affect (PA), and negative affect (NA), and the participants' satisfaction with their contact with friends and how they spend their time; and (2) to compare the evolution of these SWB-related aspects from the first to the second year of the COVID-19 pandemic. Data were collected using Google Forms and convenience and snowball sampling. Results showed that boys displayed significantly higher mean SWB scores than girls, while elementary students displayed significantly higher mean scores for the cognitive component than middle and high school students for both data collection periods. Boys also displayed significantly higher mean PA scores than girls. There were significant school grade differences on PA and NA, depending on the period of study. In the first year of the COVID-19 pandemic, children and adolescents displayed lower scores on satisfaction with their contact with friends than in the second year of the COVID-19 pandemic. These results suggest that children and adolescents adapted to the COVID-19 situation during the second year, and this adaptation protected their SWB from further decrease, as defended by the homeostasis theory.

Children’s and adolescents’ reports on their quality of life during the COVID-19 pandemic

COVID-19 has had a significant impact on human life, yet very limited studies have investigated the quality of life (QoL) of children and adolescents during the pandemic. This paper aims to present the reports of children and adolescents (N = 1,474; 10–18 years old) on their QoL during the COVID-19 pandemic in Indonesia. Data were collected using Google Forms and convenience sampling. The instruments measured the five domains of QoL: material, physical, social, emotional, and productive well-being. The data were analyzed descriptively using mean scores, crosstab, frequency, and ANOVA. The results show that the children and adolescents maintained their level of subjective well-being (SWB) and adapted to adverse situations during the lockdown. Boys and younger children displayed significantly higher mean scores than girls and older children. Children and adolescents reported boredom due to a lack of various physical activities, dissatisfaction with school closures, the things they learned at home, and their contact with friends. This study has implications in terms of providing advice to parents, teachers, children, and adolescents for promoting the QoL of children and adolescents during the pandemic.

The Structure of Children's Subjective Well-being

Research on children's quality of life and subjective well-being has advanced over the past decade largely as a result of developments in childhood theory, children's rights legislation, and the shift toward positive social science. However, in line with the uncertainty regarding the conceptualization of subjective well-being, the structural configuration of children's subjective well-being has not been considered in the literature. In the current study, we present and test a model of children's subjective well-being, which includes global (context-free items assessing overall and general well-being, without reference to a specific aspect of life) and specific (domain-based items assessing a specific aspect of life) cognitive components, and positive and negative affect. We further test the fit structure of a hierarchical structural (second-order) model of children's subjective well-being. Finally, we test the measurement invariance of the hierarchical model across age and gender. We use data from the third Wave of the Children's Worlds Survey. The data source includes a sample of 92,782 participants selected from 35 countries (girls = 49.7%) in two age groups (10- and 12-years-old). We found a good fit for the four-factor confirmatory factor model of children's subjective well-being. Correlations between the various latent factors were as anticipated-with positive correlations between the life satisfaction components and positive affect, and negative correlations with negative affect. We further found a good fit for the hierarchical structural model of children's subjective well-being. Finally, we found the tenability of measurement invariance across age and gender. The study extends the generalizability of the hierarchical structural configuration of the subjective well-being to child samples, and provides a viable model to explore correlates and predictors of children's subjective well-being using the full conceptual model. Finally, we propound the tenability of a quadripartite hierarchical conceptual model of children's subjective well-being.

Mediation of Problematic Use in the Relationship Between Types of Internet Use and Subjective Well-Being in Schoolchildren

Subjective well-being is a broad category of phenomena that includes people's emotional responses, domain satisfactions, and global judgments of life satisfaction. This research investigates how schoolchildren's subjective well-being is affected by the different types of technology use, in personal contexts, and, concurrently, whether these effects are different when the use of technology is problematic. The central hypotheses are as follows: (1) the use of the Internet affects the subjective well-being of schoolchildren negatively only when this use is problematic and (2) the effect on subjective well-being is different according to the type of Internet use. To respond to the objectives of the research, a survey was applied to 15-year-old adolescents (2,579 cases), distributed in 330 public schools, beneficiaries of a government program for the delivery of personal computers and Internet for a year. The different uses of the Internet were measured using frequency scales by type of activity (social, recreational, and educational). Problematic use scale measured the perception of negative consequences of the intensity of Internet use on a daily basis. Subjective well-being was measured by the Personal Well-Being Index-School Children (PWI-SC). Subsequently, for analytical purposes, three simple mediation models were created, whose dependent variable was PWI-SC, while its independent variables were Internet use scales differentiated by purpose (social, recreational, and educational) and problematic use as a mediating variable, as well as attributes of the subjects and their social environment, which were incorporated as control variables. The main results show that only if Internet use is expressed as problematic does it negatively affect subjective well-being. On the contrary, when the use of the Internet is not problematic, the effect is positive and even greater than the simple effect (without mediation) between these two variables. This finding is relevant, since it allows us to provide evidence that suggests that, when studying the effect that the intensity of the Internet, firstly, one must consider the mediating effect exerted by the network's problematic use and, secondly, that not all types of use have the same impact. Therefore, it is useful to enrich the discussion on subjective well-being and social integration of schoolchildren in the digital age.

Subjective Well-Being in Early Adolescence: Observations from a Five-Year Longitudinal Study

This article aims to redress the lack of longitudinal studies on adolescents' subjective well-being (SWB) and highlight the relevance of knowledge deriving from such research in designing public policies for improving their health and wellbeing in accordance with the stage of development they are in. To achieve this, the evolution of SWB during early adolescence (in adolescents aged between 10 and 14 in the first data collection) was explored over a five year period, considering boys and girls together and separately. This involved comparing different SWB scales and contrasting results when considering the year of data collection versus the cohort (year of birth) participants belonged to. The methodology comprised a generalized linear mixed model using the INLA (Integrated Nested Laplace Approximation) estimation within a Bayesian framework. Results support the existence of a decreasing-with-age trend, which has been previously intuited in cross-sectional studies and observed in only a few longitudinal studies and contrasts with the increasing-with-age tendency observed in late adolescence. This decrease is also found to be more pronounced for girls, with relevant differences found between instruments. The decreasing-with-age trend observed when the year of data collection is taken into account is also observed when considering the cohort, but the latter provides additional information. The results obtained suggest that there is a need to continue studying the evolution of SWB in early adolescence with samples from other cultures; this, in turn, will make it possible to establish the extent to which the observed decreasing-with-age trend among early adolescents is influenced by cultural factors.

The relation between subjective well-being and career aspirations amongst a sample of adolescents in low socioeconomic status communities in Cape Town

The study aimed to determine the relation between adolescents' subjective well-being and career aspirations. The study further aimed to determine the extent to which social support mediates this relation. The sample comprised 1082 adolescents in Grades 8-11, selected from schools located in low socioeconomic status communities in Cape Town, South Africa. The overall model demonstrated a nonsignificant relation between adolescents' subjective well-being and career aspirations. Across gender, the results indicated a significant relation between subjective well-being and career aspirations for the male group, but not for females. The results further indicate that social support did not mediate the relation between adolescents' subjective well-being and career aspirations for the pooled sample. However, for females, the study found a significant negative relation between social support and aspirations. We recommend targeting interventions at an institutional level, inclusive of challenging gender roles and providing information about educational and career opportunities for young people.

Diagnostic utility and therapeutic impact of PET/CT [18F]F-Fluoromethylcholine -Choline in the biochemical recurrence of prostate cancer

OBJECTIVE

To assess the diagnostic capability of PET/CT with [¹⁸F]F-Fluoromethylcholine in prostate cancer (PC) with biochemical recurrence and its therapeutic impact.

MATERIAL AND METHODS

We included 108 patients, diagnosed with PC with biochemical criteria for recurrence. A PET/CT Choline scan was performed by dynamic pelvic and whole body study at 60min post-tracer injection. The relationship between the positive studies and the PSA value was analysed by classifying patients into three groups (<1.2/1.2-2/>2ng/ml), and the diagnostic capacity was assessed with respect to pelvic MRI and the impact on the therapeutic decision.

RESULTS

The location of recurrence was identified in 85 of 108 patients (78.7%): 34 local, 47 pelvic lymph nodes and 58 distant lesions, including retroperitoneal, mediastinal lymph nodes and distant organ lesions (bone and lung). Second tumors were diagnosed in 4 patients. No significant differences were found in the percentage of positive studies depending on primary treatment. Patients with PSA>2ng/ml showed a higher percentage of disease detection than patients with a lower PSA level, with significant differences (p<0.0001). PET/CT [¹⁸F]F-Choline was able to detect local disease, not previously known from MRI, in 29.41% of patients. PET/CT Choline had an impact on therapeutic management in 67 of 108 patients (62%).

CONCLUSIONS

PET/CT with [¹⁸F]F-Fluoromethylcholine is a useful tool in the detection of locoregional and disseminated disease of PC treated with suspicion of recurrence, providing a change in therapeutic management in 62% of patients.

The subjective well-being of children in kinship care

BACKGROUND

Studying the subjective well-being (SWB) of children in out-of-home care is becoming important. However, there is a lack of results on the subjective well-being of children in kinship care. The aim of this study was to analyse and compare the subjective well-being of children at the age of 12 years old in kinship and residential care and in the general population, taking into account gender differences.

METHOD

We administered the questionnaire used in the International Survey of Children's Well-Being (ISCWeB) including two psychometric scales (OLS and PWI-SC).

RESULTS

The results showed differences in overall SWB scores (using PWI-SC as a SWB indicator) and in its components among the three groups: children in kinship care scores were more similar to those from the general population. The PWI-SC displayed good fit statistics with the pooled sample and good comparability with the Multi-group SEM with constrained loadings and intercepts, suggesting it was acceptable for comparing correlation, regressions and mean scores of the items. Gender appeared to have statistically significant effects on the OLS scale, showing lower scores for girls in residential care.

CONCLUSIONS

Supporting kinship appropriately and taking into account gender issues are the challenges facing public policies for children in care.

[Peer violence, school environment and developmental contexts: its effects on well-being]

The scope of this study is to analyze the implications of peer violence in the school context, the school environment and the perceived developmental contexts on the subjective well-being of children and adolescents. The sample is comprised of 910 students in Years 6 and 7 of primary school in 27 urban and rural public and private schools in Ceará. It is a quantitative cross-sectional study and the following tools were used: scales measuring victimization and aggression among peers and the school environment; three indices on perceptions of developmental contexts (home, school, neighborhood); and three well-being scales (Students' Life Satisfaction Scale, Personal Well-being Index and Single item on Overall Life Satisfaction). Data were analyzed using multivariate variance analysis, with a significance level below 0, 01. Results indicate that bullying, alone or in interaction with the variables analyzed, is the variable that has the greatest impact on the well-being of the population studied, whereby those involved in bullying have the lowest well-being averages. Low levels of perception regarding the contexts of home, school and neighborhood and the school environment, as well as attending a public school and/or living in rural areas, are all also associated with low subjective well-being.

Children's Experiences of Bullying Victimization and the Influence on Their Subjective Well-Being: A Multinational Comparison

The study used data from the second wave of the Children's Worlds Survey to explore the relation between children's experiences of bullying victimization (physical and psychological) and their subjective well-being (SWB) across three age groups (8, 10, and 12) and 15 global geographical regions. The sample consists of 47,029 children randomly selected from 15 countries. Data were analyzed using structural equation modeling and multigroup confirmatory factor analysis. The results show appropriate fit structure for the overall model, and that the combined influence of physical and psychological bullying made a significant contribution to SWB across age groups and geographical regions. The findings are interpreted using Cummins's (1995) Homeostasis Theory of SWB.

Postoperative adjuvant and very early salvage radiotherapy after prostatectomy in high-risk prostate cancer patients can improve specific and overall survival

PURPOSE

Adjuvant radiotherapy (ART) for biochemical relapse (BR) after radical prostatectomy (RP) showed increased disease-free survival (DFS) in three previous randomized trials. Retrospective phase II trials evaluated if early salvage RT (ESRT) is equivalent to ART. Our study aims to compare ART and ESRT to salvage RT.

MATERIALS AND METHODS

We compared RP plus ART and ESRT versus SRT. Indication for RT was made by PSA determination after RP: ART when PSA ≤ 0.2 ng/ml, ESRT when PSA ≤ 0.3 after PSA rise from 0.0 to SRT PSA ≥ 0.3. The cause of death of each patients was analyzed, DFS, cause-specific survival (CSS) overall survival (OS) and metastasis-free survival (MFS) in relation to RT intention.

RESULTS

Between 1993 and 2008, 204 patients with a median age of 65 years (44-75) were treated. The median follow-up was 160 months (28.1-273.3). At diagnosis, 89.7% had localized clinical stages and 90.2% had Gleason (G) ≤ 7. The median PSA was 10 (range 4-101). The postoperative G was ≥ 7 in 66.2%; 56.4% had ≥ 2 positive margins; 29.4% received ART, 20% ESRT and 59.3% SRT. The DFS for ART, ESRT and SRT was 74, 56 and 39% with significant differences between the three groups (p < 0.001). ART + ESRT were combined versus SRT; for the DFS, the significant differences (p < 0.001) remained 67% versus 39%. Positive margins, pT3 and pre-RT PSA were significant factors on multivariate analysis. The CSS in the ART + ESRT group was 92 vs. 78% in the SRT group (p < 0.05). OS was 69% in ART + ESRT vs. 57% in SRT (p < 0.05). MFS was 82.7% in ART + ESRT vs. 67.4% in SRT.

CONCLUSIONS

In this study the ART + ESRT presented benefits versus SRT in DFS, CSS, OS and MFS.

Introduction to the Special Section on Children's Subjective Well-Being

A notable increase in scientific publications on children's subjective well-being has been observed since the beginning of the 21st century. Different factors have contributed to this phenomenon, one of the most relevant being the concurrence of macrolevel (at the population level) and microlevel (at the individual level) perspectives in research on child well-being.

Subjective well-being and personal relationships in childhood: Comparison of Brazilian and Spanish children

This study aims to compare personal relationships satisfaction and subjective well-being of Brazilian and Spanish children and to verify if personal relationships are associated with subjective well-being for the sample. Participants are 6,747 children aged from 11 to 14 years old (M = 12.07, DP = 0.731), 1,020 being Brazilian and the others Spanish. From the total sample 50.7% were girls. Results pointed that the items of personal relationships are grouped into three components related to family, school and friends. Spanish children had higher means than Brazilians' in the items of personal relationships and in the subjective well-being scale. There is a significant association between personal relationships and subjective well-being, and the relationships with family, school and friends are predictors of children well-being in both countries. Family relationships are those with the highest contribution to the prediction of child well-being for both countries, followed by relationships at school and with friends. Personal relationships can be considered a predictor of child well-being with approximately 40% of explained variance for both countries.

Pharmacological modulation of LMNA SRSF1-dependent splicing abrogates diet-induced obesity in mice

Bakground/Objectives:Intense drug discovery efforts in the metabolic field highlight the need for novel strategies for the treatment of obesity. Alternative splicing (AS) and/or polyadenylation enable the LMNA gene to express distinct protein isoforms that exert opposing effects on energy metabolism and lifespan. Here we aimed to use the splicing factor SRSF1 that contribute to the production of these different isoforms as a target to uncover new anti-obesity drug.

SUBJECTS/METHODS

Small molecules modulating SR protein activity and splicing were tested for their abilities to interact with SRSF1 and to modulate LMNA (AS). Using an LMNA luciferase reporter we selected molecules that were tested in diet-induced obese (DIO) mice. Transcriptomic analyses were performed in the white adipose tissues from untreated and treated DIO mice and mice fed a chow diet.

RESULTS

We identified a small molecule that specifically interacted with the RS domain of SRSF1. ABX300 abolished DIO in mice, leading to restoration of adipose tissue homeostasis. In contrast, ABX300 had no effect on mice fed a standard chow diet. A global transcriptomic analysis revealed similar profiles of white adipose tissue from DIO mice treated with ABX300 and from untreated mice fed a chow diet. Mice treated with ABX300 exhibited an increase in O₂ consumption and a switch in fuel preference toward lipids.

CONCLUSIONS

Targeting SRSF1 with ABX300 compensates for changes in RNA biogenesis induced by fat accumulation and consequently represents a novel unexplored approach for the treatment of obesity.

[Psychosocial stressors, sense of community, and subjective wellbeing in children and adolescents in urban and rural areas in Northeast Brazil]

The study's overall objective was to investigate the relationship between psychosocial stressors, sense of community, and subjective wellbeing in urban and rural schoolchildren in Northeast Brazil, focusing on differences according to territorial context. The sample consisted of 757 participants, 495 from urban schools and 262 from rural schools, enrolled in the 6th and 7th grades (9 to 18 years of age) in 21 municipal and state public schools, of which 13 urban and 8 rural, in 7 municipalities (counties) in Ceará State, Brazil. The study instruments were inventory of stressful events, scale of life satisfaction for students, index of sense of community, and satisfaction indices by life domains (family, material goods, relations, neighborhood/zone, health, time, school, and personal). The results indicate that socioeconomically underprivileged public schoolchildren from urban areas are more exposed to daily stress and score lower on satisfaction in specific domains of life and on sense of community. This latter is an important indicator for evaluating wellbeing in this young population.

Relación entre soporte social, la satisfacción de vida y bienestar subjetivo en adolescentes brasileros

This study explores the subjective well-being, overall life satisfaction and perceived social support of Brazilian adolescents by analysing different models that explain the relationships among these three constructs. The sample is comprised of 1,588 adolescents (aged 12–16, 65.5% female), who answered the Personal Well-Being Index (PWI), a measure of Perceived Social Support of Family and Friends, and also an Overall Life Satisfaction single-item scale (OLS). MANOVA and ANOVA were used to assess the differences between groups, with respect to gender, it is observed that girls present lower means than boys for the OLS. Considering age, there was a significant decrease in the mean of the PWI with age. Boys present lower means of friends’ social support. Structural Equation Modelling was used to test theoretical frameworks on data. After analysing different models, the best fit model is presented using the PWI as a mediating factor between social support and satisfaction with life. The perception of social support from family and friends results to be a significant dimension of well-being among Brazilian adolescents. The importance of social support for the subjective well-being is explained by identifying how it contributes to the overall life satisfaction of adolescents.

Propiedades psicométricas del EATQ-R en una muestra de adolescentes españoles de habla catalana

The few studies that have been conducted into the psychometric properties of the EATQ-R, even fewer for the longer version, highlight the fact that its structure differs from that of the original. The aim of this study is to translate and adapt the long version of the EATQ-R to Catalan, study its internal consistency and convergent and factorial validity, and compare differences in the EATQ-R by age and gender. The EATQ-R was administered to a sample of 1481 secondary school students ranging in age from 11 to 17 years. After eliminating 40 items from the 86 comprising the EATQ-R, an adjusted model was obtained with acceptable fit indices comprising 8 of the original 11 factors.

Evidence-based recommendations of postoperative radiotherapy in lung cancer from Oncologic Group for the Study of Lung Cancer (Spanish Radiation Oncology Society)

Locally advanced non-small cell lung cancer (NSCLC) is a diversified illness in which postoperative radiation therapy (PORT) for complete resection with positive hiliar (pN1) and/or mediastinal (pN2) lymph nodes is controversial. Although several studies have shown that PORT has beneficial effects, randomized trials are needed to demonstrate its impact on overall survival. In this review, the Spanish Radiation Oncology Group for Lung Cancer describes the most relevant literature on PORT in NSCLC patients stage pN1-2. In addition, we have outlined the current recommendations of different national and international clinical guidelines and have also specified practical issues regarding treatment volume definition, doses and fractionation.
