Circadian rhythms can be demonstrated in several biomarkers and behavioural activities, with rhythmical patterns occurring roughly over a 24-h period. Circadian disorders occur in patients with cancer and may be associated with poor clinical outcomes. This scoping review aimed to identify circadian rhythm research and reporting practices, circadian rhythm patterns, circadian rhythm disorders, and relevant associations of circadian rhythm disorders in patients with advanced cancer. Studies involved adult patients with locally advanced or metastatic cancer and used objective measures of circadian rhythmicity. Two independent authors completed initial screening of title and abstracts, full text reviews, data extraction, and data checking. A total of 98 articles were highlighted in the scoping review, which utilised physical activity measures (actigraphy and polysomnography), biomarkers (cortisol and melatonin), or a combination. Several circadian rhythms are commonly disordered amongst patients with advanced cancer and have significant implications for symptom burden, quality of life, and survival. It remains unclear which patients are most at risk of a circadian rhythm disorder. Significant heterogeneity exists in research and reporting practices. Standardising this approach may address discrepancies in the current literature and allow for research to focus on the most relevant parameters and approaches to improving circadian rhythmicity.
Introduction
Circadian rhythms (CRs), repeating patterns approximately every 24 h, can be observed throughout the human body in behavioural activities, such as sleeping and feeding, and biochemical and hormonal changes, such as cortisol and melatonin secretion (1). CRs are coordinated by a central “pacemaker” or “clock” situated in the suprachiasmatic nuclei within the hypothalamus that attempts to synchronise internal body clocks with the 24-h light–dark cycle (1, 2). Additionally, areas within the brain and peripherally, such as endocrine organs, contain self-sustained secondary clocks (2).
In health, two well-established endocrine biomarkers of CRs are melatonin and cortisol, with levels being measurable in several samples, including serum, saliva, and urine (2–4). Serum melatonin begins to rise from around 22:00, peaking at around 04:00, before falling towards a baseline by 10:00, which persists throughout the day. Cortisol levels peak in the early morning, around 08:00, before falling during the day to a baseline at around 00:00 (2).
Physical activity demonstrates a circadian rhythm, with peak physical activity occurring around 14:00 and the most restful period centred around 03:00, although variability does exist between individuals (5). Circadian sleep and physical activity are primarily assessed using polysomnography and actigraphy (6). Although polysomnography and actigraphy are comparable, actigraphy can be applied in various settings and allows for prolonged periods of monitoring (6). Actigraphy utilises a wrist-worn device to detect physical movement during sleep and wake periods, with analysis of data producing several measures of circadian rhythmicity (6). Actigraphy is often accompanied by patient diaries, an approach supported by the American Academy of Sleep Medicine when investigating circadian rhythm sleep disorders (7). Diaries, however, can be burdensome, inaccurately completed, and subject to bias. Adult actigraphy research has focused on sleep–wake activity, particularly sleep onset–offset and the timing of activity phases. Various measures are used within research to describe the robustness of circadian rhythmicity or the timing and relationship of events over 24-h periods (see Table 1).
Circadian rhythmicity can alter during an individual’s lifespan and impact on health and disease. With advancing age, activity levels decline, peak activity occurs earlier, sleep becomes shorter and more fragmented, and daytime napping increases (33, 34). Circadian rhythm disorders (CRDs), where normal rhythmicity is altered, can perpetuate cancer and metabolic, neurodegenerative, psychological, and cardiovascular disease (35). CRDs are common amongst cancer patients, affecting up to 75%, and are associated with increased symptom burden, poorer quality of life, and shorter survival (36, 37). Interestingly, even misalignment between preferred and actual bedtimes is associated with cancer progression (38).
Aims
This review will broadly consider circadian rhythms of cortisol, melatonin, and physical activity in advanced cancer patients, with the aim of:
1. Identifying investigative approaches and reported parameters
2. Identifying circadian rhythm and disordered rhythm patterns
3. Identifying associations with circadian rhythm disorders, focusing on symptoms, quality of life, and survival.
Methodology
Data sources
A literature search was performed using PubMed, Embase, Web of Science, Ebsco host (CINAHL, Psychinfo, and Psycharticles), Scopus, and Cochrane on 20/04/2022. The search was updated on 05/05/2023. Keywords were restricted to title and abstract. No other limitations were placed.
Search terms
An example search strategy within PubMed is as follows: (“circadian”[Title/Abstract] OR “sleep wake”[Title/Abstract] OR “rest activity”[Title/Abstract] OR “chrono*”[Title/Abstract] OR “clock”[Title/Abstract] OR “Chronobiology Disorders”[MeSH Terms]) AND ((“advanced”[Title/Abstract] OR “progressive”[Title/Abstract] OR “palliat*”[Title/Abstract] OR “terminal”[Title/Abstract] OR “metast*”[Title/Abstract] OR “end of life”[Title/Abstract]) AND (“cancer*”[Title/Abstract] OR “malig*”[Title/Abstract] OR “tumo*”[Title/Abstract] OR “neop*”[Title/Abstract] OR “oncol*”[Title/Abstract] OR “Neoplasms”[MeSH Terms])).
Eligibility
Studies were eligible for inclusion if the patients were ≥18 years old with a diagnosis of advanced cancer (locally advanced or metastatic). “Locally advanced” differed between cancer histology and several studies included, rather than focused solely on, patients with advanced cancer. Eligible studies also had to consider objective measures of four markers of circadian rhythm disorders (sleep–wake cycles, rest–activity cycles, cortisol levels, and melatonin levels) and be fully translated into English.
Screening, data extraction, and data synthesis
Two authors (CG and JP) independently screened the title and abstract for potential full-text review. Review papers identified in the initial search were also screened for additional articles. Full-text articles were reviewed independently by two authors (CG and JP). The reference lists of included articles were searched for additional articles. Where full-text copies were not immediately available, the leading author or associated research centre was contacted, and if no full-text made available, the article was excluded. Data were extracted by a single author (CG) and confirmed independently by a second author (JP). The data extraction tool was then coded into main themes including circadian measures, circadian rhythm patterns, and the association of circadian measures with symptoms, quality of life, survival and other relevant factors. The review is presented according to the PRISMA-ScR checklist.
Results
The scoping review highlighted 98 articles, which were mainly observational in nature. The review process can be seen in Figure 1, and the results from individual studies are detailed in Tables 2A–D.

Investigative and reporting practice
Authors utilised actigraphy (n=34), cortisol (n=33), combined assessment methods (n=18), melatonin (n=11), and polysomnography (n=2) in their investigations.
Articles focused on different cancer diagnoses, including breast (n=24), gastrointestinal (n=22), mixed cancer diagnoses (n=22), lung (n=20), gynaecological (n=7), head and neck (n=2), and renal (n=1). All studies included patients with advanced or metastatic cancer; 40 studies focused solely on advanced or metastatic cancer patients.
Heterogeneity was seen in the investigational approach and the reported measures of circadian rhythm. Studies assessing melatonin used between 20 and 190 patients, sampled melatonin at 1–16-h intervals, and used between 2 and 10 different time points. Studies assessing cortisol used between 13 and 210 patients and sampled at 20-min to 12-h intervals. Sampling included fixed times, time slots, and/or were reported in relation to waking and bedtime. Melatonin and cortisol studies lasted between 24 h and 3 days for most studies.
Variation was also seen in the samples utilised. As an example, articles focusing on cortisol measures (n=30) used serum (n=14), saliva (n=16), serum and saliva (n=3), or urine (n=1) samples. Reported measures included descriptive statistics, mean levels (MESOR), variation between peak and trough levels at several time points (amplitude, double amplitude, 12- and 24-h amplitude), timing of peak level (acrophase), the area under the curve, the shape of changing levels between peak and trough levels (diurnal slope, phase angles), cortisol variability, and the change in cortisol levels on waking (cortisol awakening response, CAR).
Actigraphy studies included between 11 and 436 patients, with a duration of monitoring varying from an overnight study to 30 days. The number of reported actigraphy parameters were much larger, with overlapping characteristics. Across sleep and wake periods, the timing and duration of activities, the relative proportions between different activities, and the variability both within and between 24-h periods were considered. At least 50 different actigraphy parameters were reported. When normal actigraphy values were stated, they differed between studies. The dichotomy index (I<O), for example, which measures proportional in-bed activity to out of bed activity, was reported in 20 studies. Unfavourable, or disordered, I<O values ranged from <89.5% to ≤97.5% (17, 24, 28, 94, 95, 98, 99, 101, 104). Favourable, or regular, I<O values varied between ≥89.5% and ≥99% (8, 17, 22, 24, 28, 49, 94, 95, 98–101, 104).
Finally, polysomnography studies included between 35 and 121 patients, with the duration of monitoring varying from an overnight study to a 14-day study.
Many articles did not describe normal circadian patterns or values.
Melatonin
Melatonin patterns in advanced cancer
Significant interindividual variation in melatonin circadian rhythms was noted (9, 17). 24-h melatonin rhythms, with a peak-to-trough pattern, were noted in non-small cell lung, gastrointestinal, mixed gynaecological, and mixed cancer cohorts (9, 11, 17, 39, 40, 42, 43, 45, 46). Abnormal 24-h rhythms were noted in two studies and affected 17% of the patients with metastatic colorectal cancer and 100% of patients with small cell lung cancer (49, 51). Detailed abnormalities included a smaller evening melatonin rise and earlier dim-light melatonin onset (DLMO) for patients with a gastrointestinal cancer who demonstrate more in-bed to out-of-bed physical activity (lower I<O) (17). Smaller evening melatonin rises were also noted in patients with non-small cell lung, gastrointestinal, and cervical cancers, particularly in advanced stages (40, 41, 43, 46). Advanced breast and lung cancer patients had higher mean melatonin levels compared to early-stage disease or controls (47).
Symptoms, quality of life, and survival
No statistically significant associations were reported between the melatonin circadian rhythm parameters and symptoms, quality of life, or survival in any of the included studies.
Cortisol
Cortisol patterns in advanced cancer
Normal and abnormal rhythms were noted across cancer cohorts to varying degrees. Ten studies reported abnormal cortisol circadian rhythms in cancer patients (9, 36, 49, 60, 61, 72, 76, 79, 82, 106). This included mixed cancer cohorts (100%), ovarian cancer (75%), breast cancer (60%), and colorectal cancer (28%–56%) (36, 49, 50, 72, 76, 79, 83). Four studies noted normal cortisol circadian rhythms, including in patients with gastrointestinal (“most”), non-small cell lung (100%), nasopharyngeal cancer, and breast cancer patients (17, 39, 52, 55). Where present, abnormalities included a flattened cortisol slope, or reduced diurnal variation, coinciding with a lower morning cortisol rise and/or an increased evening cortisol (9, 12, 13, 16, 42, 54, 55, 58, 61–64, 72, 76, 77). These changes, along with the area under the curve, were more pronounced with later stage, higher grade or metastatic disease, and poorer performance status (9, 12, 13, 18, 54, 61, 64, 66, 69, 74, 76, 82). Cortisol levels at separate time points were not significantly different between cancer stages, or when compared with controls, but the overall mean 24-h cortisol was higher in cancer patients (39, 42, 52, 74). The timing of peak cortisol level (acrophase) ranged from 04:38 to 09:30 (55, 59, 82).
The change from peak to trough (cortisol slope) was unrelated to education level, marital status, age, time since recurrence, PR status, and metastatic sites in a breast cancer cohort (67). Patients with progesterone-receptor-positive breast cancer did, however, have a smaller cortisol awakening response (77). A flatter cortisol slope was associated with being male (69).
Salivary and serum cortisol were positively correlated, particularly when a strong circadian rhythm was present (16, 80).
Survival
Eight studies reported on survival, of which six report prognostic relevance of cortisol circadian rhythms. Patients with gynaecological cancer and either elevated night-time cortisol (HR, 1.802; p<0.001) or a flatter cortisol slope (HR, 1.633; p=0.001) had shorter survival (18). Conversely, patients with gynaecological cancer and more cortisol variability across the day had longer survival (HR, 0.644; p<0.001) (18). A lack of 24-h rhythmicity was prognostic in patients with lung cancer (HR, 68,052.8; p=0.009) and non-significantly in breast cancer (HR, 1.03; p=0.85) (68, 69). A flatter cortisol slope was prognostic in breast (HR, 464.9; p=0.0036) and renal cell cancer (HR, 1.88; p=0.002) (70, 81). Mean cortisol levels were prognostic in colorectal cancer (78). The early morning cortisol rise (CAR), area under the curve, and cortisol level at 00:00 were not prognostic in patients with lung cancer (61, 69). Altered cortisol rhythms in a study of patients with colorectal cancer were unrelated to survival (80).
Furthermore, a study of patients with breast cancer highlighted abnormal cortisol peaks, rather than the diurnal rhythm, to be associated with a shorter disease-free interval (r= −0.30, p=0.004) (52).
Physical and psychological symptoms
A smaller cortisol awakening response, flatter cortisol slope, and less diurnal variability were associated with increased total symptom scores, individual scores for fatigue, and interference with general activity, work, and walking (54, 64).
Within lung, ovarian, and mixed cancer cohorts, reduced diurnal cortisol variation, elevated evening cortisol, elevated morning cortisol, and higher area under the curve were associated with depression (19, 53, 54, 73, 74). Patients with steeper cortisol slopes, and therefore healthier rhythms, expressed less negative affect during psychological therapy and demonstrated more post-traumatic psychological growth following diagnosis, and those with flatter cortisol slopes were found to repress emotions (14, 67, 79). Abnormalities, including higher waking cortisol and lower cortisol awakening response, were associated with antidepressant use in patients with breast cancer (77). Some studies reported no significant correlations between cortisol levels, or cortisol slope, and psychological measures (12, 70, 73).
Quality of life
Flattened cortisol slopes, less cortisol variability, and elevated evening cortisol were associated with reduced physical well-being in patients with ovarian cancer (18, 54). Conversely, cortisol rhythms were also not correlated with quality-of-life measures for patients with breast cancer (65).
Other
Abnormal cortisol peaks during sleep, coinciding with waking episodes, were reported in a subset of metastatic breast cancer patients (52). More frequent and longer lasting wake episodes and a progressive later waking time were also seen with flatter cortisol slopes (66, 75, 81).
The cortisol slope was correlated with the CAR, rather than waking level, and flatter slopes were associated with higher evening cortisol levels and an escape from cortisol suppression (63, 77).
Actigraphy
Actigraphy patterns in advanced cancer
Of the studies comparing patients with cancers to controls, 90% found abnormal actigraphy activity parameters in patients with cancer (17, 20, 23, 28, 30, 32, 85–88). Due to several reported parameters, the dichotomy index (I<O), 24-h autocorrelation coefficient (r24), and sleep efficiency (SE) are noted as examples.
Between 30%-95% of patients had a disrupted dichotomy index (I<O), suggesting proportionally more in-bed to out-of-bed activity, with average group values of 79%–98% (individual values of 49%–100%) (17, 21, 22, 24, 28, 37, 78, 87, 89, 94–96, 98–100, 104–106). Lower values suggest proportionally higher in-bed to out-of-bed activity. I<O values were lower in men, those with metastatic disease, and a poorer performance status (89, 99, 106). The I<O was reported to be the most discriminative parameter for cancer patients, although a large inter-subject variability was noted (17, 28).
Approximately 26%–28% of patients had a disordered 24-h autocorrelation coefficient (r24), representing the dissimilarity of rest–activity rhythms (RARs) between days, with average group values of 0.19–0.57 (individual values of −0.06–0.77) (15, 24, 32, 37, 49, 65, 71, 78, 88, 100, 105, 106). A r24 approaching 1 represents a prominent RAR (105). r24 values were lower in those with poorer performance status and in African-American women (37, 65, 105, 106).
Approximately 12%–88% of patients had disordered sleep efficiency, which measures sleep during time in bed, with average group values of 71%–92% (individual values, 20.2%–100%) (10, 15, 20, 22–27, 29, 30, 32, 68, 75, 85, 87, 91, 94, 97, 100, 102, 103). Higher values suggest that more time in bed has been spent sleeping, and lower values suggest that more time in bed has been spent awake.
Some studies reported circadian actigraphy parameters were unrelated to performance status, whilst others reported that time awake spent immobile (TASI), I<O, r24, and mean activity were significantly correlated with performance status (8, 17, 31, 37, 50, 78, 89, 99, 105, 106).
Survival
A total of 12 studies commented on survival and all linked circadian disruption to survival. Stronger RARs evidence by improved dichotomy index (I<O), 24-h autocorrelation coefficient (r24), physical activity amplitude and MESOR, nighttime restfulness, sleep efficiency, and time awake spent immobile were associated with longer survival in patients with colorectal, breast, head and neck, non-small cell lung, and mixed cancer diagnoses (8, 9, 31, 37, 68, 78, 89, 93, 98, 99, 104, 105). In a mixed cancer cohort, disordered I<O was not prognostic; however, r24 and sleep efficiency were prognostic (89).
Examples of prognostic relevance include colorectal and mixed cancer cohort patients with an I<O <97.5%, or below median I<O, having a reduced overall survival (OS) of between 2.1 and 9.7 months, and reduced progression-free survival (PFS) of 4.2 months (98, 99, 104). Similarly, patients with colorectal cancer and an I<O ≥99.2% had 11.5 months longer survival than those with an I<O <92.4% (105). The I<O was an independent prognostic factor when accounting for factors including age, gender, performance status, cancer diagnosis and stage, previous chemotherapy, and surgery (98, 99, 104). Similarly, sleep efficiency was an independent risk factor for patients with breast cancer whereby those with a sleep efficiency >85% had over a double survival compared to those with poor SE (68). However, I<O, r24, mean activity, and sleep activity parameters were reported also reported to not be significantly correlated with overall survival or progression-free survival (68, 89, 92, 104, 105).
Physical and psychological symptomatology
Abnormal circadian activity rhythms were associated with pain, fatigue, drowsiness, nausea, vomiting, anorexia, and weight loss (20, 27, 37, 50, 78, 101, 106). Higher I<O values were specifically associated with less pain, fatigue, anorexia, sleep disturbance, constipation, and dyspnoea, and improved sleep quality (95, 100, 105, 106). Higher r24 values were specifically associated with less insomnia, daytime dysfunction, fatigue, anorexia, pain, and dyspnoea (20, 30, 100, 105). Higher sleep efficiency was associated with less pain (92). Greater time to sleep once in bed (sleep onset latency, SOL), wake after sleep onset (WASO), and time in bed (TIB) were associated with gastrointestinal symptoms in a mixed cancer cohort (92). Increase time spent napping was associated with increased pain, fatigue, and daytime sleepiness (92). No association between circadian activity parameters and pain or fatigue was found in a mixed cancer cohort (8).
Lower sleep efficiency, I<O, r24, and mean activity along with increased time spent napping or in bed were all associated with increased depression (37, 50, 75, 92, 93, 106). A lower r24 and more daytime inactivity were associated with intrusive thoughts and avoidant coping in patients with breast cancer (71). Studies also reported that anxiety and depression were not associated with sleep–activity rhythms, including the I<O (8, 17, 23).
Quality of life
Circadian disruption was associated with interference with activity, work, relations, and enjoyment of life for patients with colorectal cancer (95). Improved r24, I<O, and meanAct were associated with improved global QoL, along with health, physical, social, and functioning subscores (20, 50, 78, 95, 96, 105, 106). A lower amplitude and MESOR and a later acrophase were associated with worse global QoL in a mixed cancer cohort (8). The strongest correlation between an actigraphy parameter and quality of life measure in a mixed cancer cohort was the 24-h correlation coefficient (32). Studies also noted that circadian parameters were not associated with the fatigue, emotional, or cognitive subscales of quality-of-life measures (105, 106). One study of patients with breast cancer noted that WASO and r24 were unrelated to global QoL (65).
Other
There were mixed reports regarding chemotherapy response and circadian rhythmicity in patients with colorectal cancer. One study noted that disordered rhythmicity during chemotherapy was associated with earlier death but not to objective response or toxicity, while another study noted objective response to be influenced by r24 and I<O (37, 104). Patients receiving chemotherapy who also had evidence of circadian disruption were more likely to experience weight loss and fatigue (101).
I<O appeared to correlate with circadian temperature rhythms, self-reported physical activity, and chronotype (17). More robust circadian rhythms were associated with greater light exposure (8).
Subjective and objective measures differed for physical activity but were closely correlated for sleep (27, 102). Subjective sleep disruption and circadian disruption can occur together or independently (22). Although total sleep time (TST), SE, and WASO were associated with subjective sleep quality, physical activity measures were also not significantly different between those who report their sleep as good or poor (26, 29, 37, 85, 102).
Subjective scores of pain and physical function correlated with objective physical activity, and those using analgesia had more abnormal circadian activity rhythms (84, 105). Daytime sleep, or inactivity, was related to sleep medication use, night-time sleep disturbance, daytime dysfunction, night-time sleep, and sleep quality (30, 38, 108). Sleep efficiency was reported to be correlated with chest metastases, hormone use, and radiotherapy (75). Patients with a higher r24 had less daytime dysfunction and less insomnia (20, 30). Circadian disruption was associated with tumour progression markers (15).
Polysomnography
Patients with cancer spent more time in bed were noted to have multiple nocturnal awakenings and had an average sleep efficiency of up to 77.2% (91, 107, 108). Increased daytime sleep was associated with less night-time sleep and more nocturnal awakenings in a mixed cancer cohort (108). Medications were also found to impact on sleep. Anticancer therapies were associated with increased sleep efficiency, whereas beta blocker use was associated with reduced sleep efficiency (108). Sleep efficiency was higher in women, white patients, and those with a higher education level (108).
Correlations between measures of circadian rhythm
Increased diurnal physical activity variability was associated with increased diurnal melatonin and cortisol variability along with an earlier DLMO (17). Salivary cortisol levels appeared unrelated to I<O, cortisol rhythmicity positively was correlated with r24, and more robust actigraphy rhythms were associated with a steeper cortisol slope (17, 37, 71).
The dichotomy index was correlated with r24, mean activity, sleep motor activity, sleep efficiency, and WASO (28, 89). r24, I<O, and mean activity were also correlated (106).
Higher I<O and r24 were associated with improved sleep efficiency (100).
Polysomnography-derived values for sleep efficiency were lower, and wake after sleep onset higher, than actigraphy-derived values (91).
Discussion
This review supports, expands upon, and updates several previous reviews of circadian rhythmicity in patients with advanced cancer. It highlights that, for several patients with advanced cancer, disordered cortisol, melatonin, and physical activity circadian rhythms are associated with increased symptom burden, poorer quality of life, and shortened survival. Other important associations with CRDs include poorer performance status and raised biomarkers of tumour progression.
A review of rest–activity rhythms in advanced cancer patients found that CRDs are particularly evident amongst men, those undergoing chemotherapy, and those who were symptomatic (109). Additionally, circadian disruption may be seen across the cancer trajectory, with worse biopsychosocial outcomes reported in cancer survivors who have disordered cortisol rhythms (110). This review highlights that circadian rhythms may be maintained in some patients with cancer and that wide inter-individual variation exists. Future research aimed at identifying patients that are at risk of circadian rhythm disorders, and impacted by their associations, is important, particularly when considering interventional studies to improve circadian rhythms and patient outcomes.
Articles were predominantly observational in nature, and many studies lacked a control group. Causality is difficult to establish, particularly due to the bi-directional relationship between cancers and circadian rhythm disorders, and the influence from external factors. CRDs impact on several neuroendocrine-immune functions, including inflammatory responses and hormonal secretion, and predispose individuals to developing cancer (111). Cancer in turn generates a pro-inflammatory state, and increased circulating cytokines levels can disrupt circadian rhythms (111). Rest–activity patterns are influenced by age, sex, race, education, and voluntary behaviour (6, 112). Cortisol values are influenced by sex, age, body mass index, menstrual cycle, sleep disturbances, renal disease, and acute illness, for example (4). The review highlights studies of patients prior to, during, and after anticancer therapies, and within the inpatient and community setting. Limited information on previous and current therapeutic regimes, and location of metastatic disease, limits the ability to synthesise findings. Potential modifying factors of circadian rhythmicity should be reported and taken into account when reviewing findings (113).
CRDs and their impact are not solely seen in cancer patients. Circadian disruption has been reported in patients with neurodegenerative conditions including Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease (114). Despite conflicting findings, evidence highlights altered rest–activity, body temperature, melatonin, and cortisol rhythms within this population and associations with physical and psychological well-being, and quality of life (114). At present, the similarities in circadian disruption between clinical conditions are not clear.
Furthermore, the review highlights heterogeneity in the investigation and reporting of circadian rhythms in cancer patients and a lack of threshold values to identify circadian parameter abnormalities. Several reporting measures, overlapping definitions, and an absence of clear definitions were found in the investigation of circadian rhythms, particularly when using actigraphy. Heterogeneity in actigraphy research is not limited to cancer populations. A review of 126 actigraphy studies of children highlighted a lack of standardisation in actigraphy practice, including the reporting of epoch length, artefact detection, and definition of variables (115). Additionally, within cohorts of bipolar disorder patients, over 30 possible actigraphy parametric and non-parametric measures were reported (116). In this review, only four actigraphy parameters (I<O, r24, mean activity, and SE) were associated with at least three of the areas of interest (physical symptoms, psychological symptoms, quality of life measures, and survival). Although a wealth of information can be obtained using actigraphy, the reporting parameters should be aligned with the overall study objectives to allow a clear message in the literature. Analysis of actigraphy data takes many forms and lacks standardisation (6, 112). Similarly, variable sampling protocols, analysis, and reporting practices has been seen in cortisol and melatonin studies (3, 110). When faced with such heterogeneity in approaches, it is challenging to make firm conclusions, and standardisation may improve research practice. The development of recommendations to identify, and subsequently report, optimal sampling processes, particularly the frequency and timing of samples, and the calculation of circadian parameters are required.
Actigraphy data can report the timing of events, duration of events, or relationship between events. Although studies may focus on “sleep–wake” or “rest–activity” periods, there is significant overlap. Diagnostic criteria have been formulated for circadian rhythm sleep–wake disorders by American Academy of Sleep Medicine (117). The diagnosis considers the timing of sleep onset and offset, and the presence of jet lag or shift work, to categorise patients into seven different diagnoses. Many studies of advanced cancer patients reported actigraphy measures across the 24-h period rather than focusing on this timing of sleep onset–offset. The circadian activity rhythm disorders in cancer patients are likely separate to intrinsic circadian sleep–wake rhythm disorders. Recent international consensus recommendations have been developed for the assessment and diagnosis of circadian rest–activity rhythm disorders (CARDs) (118). The recommendations outline key modifiers of circadian rhythmicity, areas to consider within a clinical history, patient sleep and activity diary, and accelerometery during assessment, and criteria to diagnose a CARD. Diagnostic criteria of other forms of CRDs do not currently exist.
The scoping review was strengthened by using independent authors at multiple stages of the review process. Additional evidence was actively sought through hand searching review papers and reference lists. The scoping review is inclusive of available evidence and placed minimal limitations in the search strategy. It made no attempt to critically analyse the quality of evidence. Although the review aimed to focus on advanced cancer patients, several studies included non-advanced cancer patients. This approach may dampen associations, but it was felt to be more inclusive and to provide a broader insight of the topic. Furthermore, the review did not exclude several confounding factors in selected articles, such as medications and chemotherapy. This information was not available in several studies, and through exclusion, it would have limited the generalisability of the findings. Studies reporting on circadian rhythmicity in patients with cancer would benefit from detailed information on recent and existing modifiers of circadian rhythmicity, and the presence and location of metastatic disease.

■ What are the optimal measurement and analytical approaches when assessing cortisol, melatonin, and rest–activity circadian rhythms?
■ What are the abnormal threshold values for cortisol, melatonin, and rest–activity parameters when diagnosing a circadian rhythm disorder?
■ Do current investigative approaches translate into the clinical setting, considering the ease and acceptability for patients and clinicians?
Conclusion
Cancer patients, particularly those with advanced disease, are at risk of circadian rhythm disorders and significant associated complications. It remains unclear which subset of patients are most susceptible. Conflicting results within the review highlight the need for further studies to identify patient populations that are most impacted by circadian rhythm disorders. Current investigative approaches require a multiple sampling approach (blood, urine, and saliva) or a prolonged period of activity monitoring. In the clinical setting, and advanced cancer population, this may require an alternative approach. Current gaps in the literature are highlighted in Box 1. There needs to be an attempt to standardise research approaches and reporting practice within circadian rhythm research and to develop criteria to identify circadian rhythm disorders. Research standardisation and targeted approaches may help in future research aimed at developing management approaches to circadian rhythm disorders.
