14、be6%-10%in the general population and three times greaterin patients with cancer and cancer survivors.1,5Moreover,up to 95%of patients with cancer report sleep disturbancesduring the disease and treatment trajectory,as well as insurvivorship and near the end of life.8Variations ininsomnia symptoms m

19、 an increased risk ofmental and physical health problems,including irritability,anxiety,depression,impaired QoL and greater disability andmortality,both in the general population and specifically inoncology.14Decades of research into the causes of chronic insomniahave identified physiological,cognit
20、ive and emotionalarousal as key factors.Hyperarousal and increased mentaland physiological stress-reactivity have been hypothesisedto contribute to the maintenance of insomnia by interactingwith negative cognitions,dysfunctional beliefs about sleepand negative sleep-related behaviours.The allostatic
21、 loadtheory suggests that sleep loss is both a precipitant of stressand a consequence of it,with evidence to suggest thatinsomnia-related stress may lead to persistent dysregulationof multiple biological systems15and various adverse cancer-related outcomes.Furthermore,stressors and challengesrelated
22、 to cancer and its treatment can cause insomnia orworsen existing insomnia,which then exacerbates comorbidmedical conditions such as pain,psychiatric conditions,daytime fatigue and somnolence,sleep-disordered breath-ing and napping-associated pain increase.16Thus a delete-rious feedback loop may be
23、created which maintains orexacerbates insomnia and cancer-related comorbid condi-tions,including depression,anxiety,post-traumatic stressdisorder symptoms,daytime fatigue and pain.Symptoms of insomnia,depression and fatigue canmaintain and amplify each other in patients with cancer viamultiple mecha
24、nisms.Insomnia may lead to depression bydysregulating multiple systems involved in mood disorders.It is associated with a marked decrease in T cells andincreased levels of proinflammatory markers,such asC-reactive protein,interleukin-6 and tumour necrosis factor,and may promote a state of chronic in
25、flammation whichcontributes to depression.However,the role of insomnia inmodulating the onset and outcome of cancer remainsunclear.17Cancer-related fatigue is a syndrome characterised byphysical,mentalandemotionalsymptoms,includinggeneralised weakness,diminished concentration or atten-tion,reduced m
26、otivation to engage in usual activities andemotional lability,similar to the symptoms that characterisedepression.18The aetiology of cancer-related fatigue maybe best explained by a multifactorial model that considersnot only the biological mechanisms but also psychologicaland behavioural factors,in
27、cluding insomnia,which has beenidentified as one of seven factors most commonly associ-ated with cancer-related fatigue.Several biological mecha-nisms may explain the bidirectional associations amongcancer-related insomnia,depression and fatigue,includingcytokine and hypothalamicepituitaryeadrenal a
28、xis dysre-gulation.18Treatment of insomnia is therefore recom-mended,not only in patients undergoing active cancertreatment,but also in long-term cancer survivors and pa-tients undergoing palliative care.Persistent insomnia in cancer may become a perpetu-ating factor in a vicious cycle of fatigue,de
29、pression andother cancer-related symptoms.These are promoted byinsomnia-related dysregulations of the immune and endo-crine systems,in combination with the effects of cancertreatment and the cancer itself.Insomnia can have signifi-cant consequences in patients with cancer,including anincreased risk
30、of infection,persistent symptoms afterchemotherapy(ChT)and poorer recovery from depressionand anxiety,leading to reduced overall well-being andQoL.19Assessing insomnia and providing efficacious in-terventions can help to alleviate symptoms and late effects,as well as improving mental health,physical
31、 health and QoLin patients with cancer and cancer survivors.RISK FACTORSThe currently accepted risk factor model for insomnia is thediathesisestress model,commonly known as the 3-Pmodel,which describes predisposing,precipitating andperpetuating factors relevant to the development andmaintenance of p
32、ersistent insomnia.In patients with can-cer,the 3-P model is useful for understanding the interac-tion between the general and cancer-specific factorsinvolved in cancer-related insomnia(see SupplementaryTable S2,available at https:/doi.org/10.1016/j.esmoop.2023.102047).Predisposing factors for insom
33、nia are genetic,physio-logical and psychological factors that confer differentialsusceptibility to individuals in their sleep-related responsesto stress.Such factors include advanced age,female sex,ananxiety-prone personality,tendency to ruminate and afamily or personal history of insomnia and/or an
34、xiety ordepression.Circadianrhythmdisruptioncouldalsocontribute to the development of insomnia in thesepatients.Precipitating factors include physiological,environmentaland psychological stressors which may interact with pre-disposing factors to produce acute insomnia symptoms.Patients with cancer a
35、nd cancer survivors are exposed todifferent types of precipitating factors for insomnia alongthe cancer trajectory.These include stress and distressrelated to the cancer diagnosis and cancer treatments,suchas ChT,radiotherapy and hormone therapy.Cancer itself,aswell as surgery,hospitalisation,sympto
36、ms and varioustreatment-relatedside-effects,maydisruptcircadianrhythms and contribute to insomnia.In some cancers(e.g.breastcancer),antihormonaltreatmentsmayinducemenopausal symptoms contributing to the development ofsleep disorders.Perpetuating factors include behavioural,cognitive andenvironmental

42、 acomplaint of dissatisfaction with sleep quantity or quality,associated with one or more of the three main symptoms(i.e.difficulties falling asleep,staying asleep and earlyawakening),with sleep difficulty occurring?3 nights perweek,lasting?3 months,persisting despite adequate op-portunities for sle
43、ep and causing significant impairmentin daily life.Insomnia can be episodic(symptoms lasting?1 month but 3 months),persistent(symptoms lasting?3 months)or recurrent(at least two episodes within thespace of 1 year).In this framework,insomnia is considereda 24-hour sleepewake disorder,characterised by
44、 bothnocturnal and diurnal symptoms.The insomnia criteria in ICD-11 are the same as in DSM-5-TR,but ICD-11 specifies the symptoms secondary to sleepdifficulties(e.g.fatigue or malaise;attention,concentrationor memory impairment;mood disturbance or irritability).ICD-11 also classifies insomnia as sho

47、aladaptive sleep patterns and track treatment effects.34The Consensus Sleep Diary(CSD)35was developed by anexpert panel and asks patients to record their sleep,including the time they went to bed,the time they tried tofall asleep,how long it took them to fall asleep,how manytimes they woke up,how lo
48、ng these awakenings lasted,thetime of their final awakening,the time they got out of bedand the perceived quality of their sleep.Objective measures of sleep such as polysomnography oractigraphy are not routinely required for insomnia diagnosisand evaluation but can be considered as a part of detaile
