Study population: To allow for balanced sex groups, we will include patients according to the following stratification : ICI: 100 F/100 M; ICI+ CT/RT: 100 F/100 M. Due to the current ICI use in clinical practice we are expecting to mainly populate the ICI strata during the first recruitment period. As the recruitment progresses, the sample will be enriched of ICI+CT and ICI+RT treated patients, since combinations are expanding for many cancers such for instance melanoma, lung and head and neck

Brief summary: The study aim is to investigate the differences between sex and gender in the immune-related adverse events (irAEs) development associated with immune checkpoint inhibitors (ICI) treatment. The study will be a multicenter prospective observational study focusing on biological differences between females and males, possibly affecting discrepant irAEs incidence.

Detailed description: The study aim is to investigate the differences between sex and gender in the immune-related adverse events (irAEs) development associated with immune checkpoint inhibitors (ICI) treatment.

In common feeling, sex and gender represent the same concept, that is the traditional division of individuals into females (F) and males (M) defined by differential organization of chromosomes, reproductive organs, and sex steroid levels. However, if going beyond these aspects, which characterize "sex", it can be observed how the differences between people are also characterized by behaviors and relationships that are the product of the culture and sociality typical of human beings. This is what is called "gender", i.e. the process of social and cultural construction that determines the behaviors that give life to the status of an individual. Gender is therefore learned and not innate. Sex and gender do not constitute two opposing but interdependent dimensions: the process of determining gender identity is triggered on biological characters. The relationship between sex and gender varies according to geographical areas, historical periods and cultures.

Sex influences the adaptive immunity, and may influence irAEs types, frequency and severity. Together with genetic and biological differences, the roots of irAEs inequalities between F and M could be linked to psycho-social and behavioral determinants. IrAEs usually develop within the first few weeks to 6 months after treatment initiation; however, they can also present after cessation of ICI therapy. Most studies indicate that prolonged treatment does not result in an increased cumulative incidence of irAEs. Accumulating evidences support the existence of sex-driven differences in immune responses as potential factors contributing to disease outcome and response to therapy. Increasing use of ICI is associated with immune-related adverse events caused by non-specific activation of the immune system.

The investigators will conduct a multicenter prospective observational study investigating sex differences in irAEs in relation to clinical factors and genetic, immunological and hormonal profiles. By focusing on biological F/M differences possibly affecting discrepant irAEs incidence, sex inequality will be explicitly addressed and complemented by the exploration of association between gender dimension and irAEs development. Exploring the irAEs occurrence in a "real world" (outside RCT) context will be more easily translated in a ready-to-use personalized approach to irAEs timely diagnosis and treatment.
