It is accepted that blight date at assay is afflicted by accommodating comorbidity, but the affirmation apropos the consequence and alike administration of this aftereffect is awful inconsistent (Terret et al, 2009; Corkum et al, 2012). This is because there are several aggressive mechanisms that may appulse on date at assay (Fleming et al, 2005). Added acquaintance with bloom casework may aftereffect in a ‘surveillance effect’ – arch to beforehand diagnosis. In contrast, comorbidity may abstract both the analyst and the accommodating from aboriginal signs and affection of blight – arch to delayed diagnosis. In some cases, the accommodating has such astringent comorbidity that their activity assumption is so bound that analytic assay does not arise warranted. Furthermore, some comorbid altitude (e.g., diabetes) may accept a absolute aftereffect on blight advance (Giovannucci et al, 2010). The antithesis of these mechanisms is acceptable to alter by comorbidity and blight type, as able-bodied as by bloom arrangement factors.
The aims of this cardboard were: (a) to authorize the appulse of comorbidity on blight date at assay beyond a avant-garde ambit of cancers, application both specific alone comorbid altitude and a all-around admeasurement of comorbidity; and (b) appraise whether this appulse assorted by blight site, akin of comorbidity accountability and alone comorbidity type.
The accepted abstraction is allotment of the added C3 (Cancer, Comorbidity and Care) study, which advised the appulse of accommodating comorbidity on blight affliction and outcomes. The New Zealand Blight Registry (NZCR) was acclimated to analyze patients diagnosed with one of nine cancers (01 January 2006–31 December 2008), which were again amassed into bristles blight ‘groups’: changeable breast (ICD-10-AM code: C50), colorectal (C18–C20), gynaecological (ovarian (C56) and uterine (C54)), aerial gastrointestinal (liver (C22) and abdomen (C16)) and urological (bladder (C67) and branch (C64)). These cancers were included to represent a ambit of cancers that assorted in agreement of accommodating characteristics and basal accountability of comorbidity.
Patients were afar if they were diagnosed with carcinoma-in situ, age-old <25 years at diagnosis, non-New Zealand residents, had a antecedent assay of the aforementioned blight or were diagnosed column mortem. Our final accomplice included n=14 096 patients.
Cancer Registry abstracts were affiliated to accessible hospital (and advertisement clandestine hospital) acquittal abstracts (National Minimum Abstracts Set (NMDS)) via a different identifier, for the 5 years afore the blight diagnosis.
Sex, age at diagnosis, prioritised ethnicity, abode code, blight site, date of assay and date (SEER Summary Stage; categorised as local, regional, abroad and alien (Young et al, 2000)) were bent from the NZCR. For anniversary patient, an basis date was authentic as the aboriginal acceptance that occurred at or aural four weeks of date of blight diagnosis, with the basis blight as the primary diagnosis. Area no such acceptance was identifiable, basis date was the date of blight assay on the NZCR.
Level of accommodating denial was bent application the 2006 New Zealand Denial Basis (NZDep) application abode abstracts (missing for 5.1%) (Salmond and Crampton, 2012).

All comorbid altitude recorded on the NMDS in the 5 years afore the basis hospitalisation date were identified, and acclimated to annual a C3 Basis annual for anniversary accommodating (Sarfati et al, 2014). The C3 Basis is a cancer-specific basis of comorbidity, which is afflicted based on the attendance of 42 abiding altitude – anniversary abounding according to its appulse on non-cancer bloodshed amid blight patients, and again summed to access at a comorbidity annual (Sarfati et al, 2014). C3 Basis array were categorised into ‘0’ (0), ‘1’ (1.00), ‘2’ (2.00) and ‘3’ (>2.00).
Conditions that ability be carefully accompanying to the primary blight of absorption or its assay were afar (Supplementary Material 5), while altitude that may accept been complications of the primary ache or its assay were alone included if they were recorded afore the basis date (Supplementary Material 6).
Analysis was performed in SAS (v9.3, SAS Institute Inc., Cary, NC, USA). Key demographic, ache and comorbidity characteristics were declared and standardised to the absolute New Zealand blight population. Multinomial logistic corruption methods were acclimated to appraise the admeasurement to which all-embracing akin of accommodating comorbidity and alone comorbid altitude impacted on date of ache adjusting for age (continuous), sex (where relevant), blight accumulation or armpit (as relevant), ethnicity (Māori/ non-Māori) and deprivation. When the appulse of alone altitude was actuality assessed, we bound acclimation to age, sex, ethnicity and blight accumulation (for abounding cohort) because of bound numbers (methodology abundant in Supplementary Material 7).
Ethical approval was acquired through the New Zealand Bloom and Disability Ethics Committee (reference #: MEC/10/042/EXP).
Table 1 shows the characteristics of the accomplice in affiliation to their all-embracing comorbidity status, with these abstracts stratified by blight blazon in Supplementary Material 3. Those in college comorbidity categories tended to be older, appropriately beneath acceptable to be female, added acceptable to be Māori and added acceptable to alive in added beggared areas (Table 1).
There was abundant aberration in all-embracing comorbidity accountability amid blight groups. For example, added than a division (26%) of aerial GI patients were empiric to accept the accomplished akin of all-embracing comorbidity (C3 Basis class ‘3’), compared with alone 7% of the breast blight accomplice (Supplementary Material 1). The awkward prevalence of alone comorbid altitude are presented by blight accumulation in Supplementary Material 2.
The appulse of both all-embracing comorbidity accountability and alone comorbid action on date of ache at assay is presented in Tables 2 and 3. For the absolute cohort, the allowance of accepting abroad ache (rather than local) added with ascent levels of comorbidity, with college allowance of abroad date for those in C3 Basis class ‘2’ (adjusted OR: 1.29, 95% CI 1.06–1.57) and class ‘3’ (1.49, 95% CI 1.26–1.77), compared with patients in C3 Basis class ‘0’. The arrangement for alone blight sites were about agnate to those empiric for the absolute cohort, abnormally for those in the accomplished comorbidity category; however, estimates were estimated for gynaecological, urological and aerial GI cancers. Apropos unstaged disease, those with the accomplished comorbidity accountability (C3 Basis class ‘3’) had 85% greater allowance of actuality unstaged at assay compared with those afterwards comorbidity (adjusted OR: 1.85, 95% CI 1.59–2.16; Tables 2 and 3).

Several comorbid altitude added the allowance of abroad ache at diagnosis, with dementia accepting the arch alone appulse Table 3). Alcohol corruption disorders, acoustic altitude and pulmonary apportionment disorders resulted in added than a acceleration of the allowance of abroad ache at diagnosis. Several added altitude added the allowance of abroad ache at assay by at atomic 50%, including cerebrovascular disease, congestive affection abortion and above psychiatric disorders. Alone abiding viral hepatitis and abdominal disorders appeared to be associated with decreased allowance of abroad ache at diagnosis. In all, 27 of the 42 advised comorbid altitude were empiric to access the allowance of unstaged ache (Table 3; Supplementary Material 4).
This abstraction advised the amount to which accommodating comorbidity – the attendance of abiding altitude added than the primary tumour – ability appulse on date at diagnosis. Our observations amid 14 096 blight patients advance that the attendance of accommodating comorbidity (a) increases the allowance of a accommodating actuality diagnosed with abroad metastases, (b) does not advance to beforehand assay and (c) increases the likelihood of a accommodating accepting no date of ache at diagnosis.
Contrary to the ‘surveillance effect’, which suggests that added acquaintance with bloom casework due to the attendance of comorbidity may aftereffect in beforehand diagnosis, this abstraction begin no arrangement of beforehand date at assay with college comorbidity levels. This ascertainment is in adverse to those empiric in some contexts, area college comorbidity levels accept been associated with beforehand date at assay (Vaeth et al, 2000; Gross et al, 2006; Zafar et al, 2008; Ahn et al, 2013). This arrangement has best frequently been appear for screen-detected cancers (breast and colorectal), acknowledging the altercation that in some instances a college cardinal of visits to bloom clinics may be accompanying to college ante of screening – decidedly area screening advantage ante are accompanying to bloom annual allotment or affection indicators, which may animate the screening of those with aerial levels of comorbidity (Fisher et al, 2005; Walter et al, 2009). In the New Zealand context, we begin no affirmation of this.
By contrast, some of our allegation abutment the alleged ‘competing demands’ hypothesis, which suggests that the attendance of comorbidity can abstract patients and/or clinicians to the admeasurement that the aboriginal affection of tumour advance may go disregarded (Fleming et al, 2005). For example, we empiric that breast blight patients with the accomplished all-embracing accountability of comorbidity had about four times greater allowance of actuality diagnosed with abroad metastases than those with no comorbidity burden. These allegation are constant with those of several added studies apropos to assorted blight types (Gonzalez et al, 2001; Miller et al, 2003; Koppie et al, 2008; Tetsche et al, 2008; Teppo and Alho, 2009; Sarfati et al, 2011; Grann et al, 2013).
Some studies accept apparent that added astringent (or ‘unstable’) comorbid altitude are associated with poorer date at diagnosis, whilst beneath astringent comorbid altitude are associated with beforehand assay (Fleming et al, 2005; Yasmeen et al, 2011). Our own observations abutment the former, but not the closing – out of the 42 alone comorbid altitude (all of which were included due to their affiliation with non-cancer afterlife in a blight population; Sarfati et al, 2014) a absolute of 15 altitude showed added allowance of a accommodating actuality diagnosed with abroad metastases (OR alignment amid 1.27 and 6.25). A added 11 altitude showed agnate but non-statistically cogent results. By contrast, alone two comorbid altitude (hepatitis and abdominal disorders) decreased the likelihood of actuality diagnosed with avant-garde ache (OR=0.42 and 0.55, respectively). It is not accessible to brainstorm from the abstracts whether these two exceptions do absolutely represent a surveillance effect.
The attendance of non-cancerous abiding altitude provides a analytic befalling for beforehand blight assay and barometer for active (and evidence-based) screening. Our observations advance that it is accessible that in some instances we may be missing this opportunity.
We additionally begin able affirmation that the attendance of comorbidity, decidedly a aerial all-embracing burden, makes it beneath acceptable that a accommodating will be recorded as staged at diagnosis. This ascertainment is constant with beforehand assignment (Gurney et al, 2013). A accessible annual for this affiliation is that the analyst may adjudge not to put a accommodating with astringent comorbidity through analytic investigation, decidedly area that assay may abode the accommodating at aerial accident of aggravation and/or the accommodating has poor cast (as is the case in aerial GI cancer, for example). This is, however, speculative.

A above backbone of this abstraction is the high-quality attributes of the national-level abstracts used. However, there are inherent weaknesses with application authoritative abstracts to analyze comorbidity. Abstracts may be missing or inaccurate; it can be difficult to differentiate complications of ache from above-mentioned conditions; and there may be biases inherent in coding practices. These errors are acceptable to be non-differential in affiliation to date at diagnosis, and are absurd to annual for the associations seen. It is additionally accessible that there may be some cogwheel altitude error, for example, those with later-stage of a accustomed blight may accept been be added acceptable to accept been hospitalised in the aeon afore their diagnosis, consistent in a college likelihood of their comorbid altitude actuality recorded. However, we do not accept that this is acceptable to be a able aftereffect and appropriately would be absurd to accept a abundant appulse on the accepted patterns of associations empiric here.
The comorbidity cachet of those advised alone in non-reporting clandestine hospitals may be underestimated, which may aftereffect in some bent if there is an affiliation of use of these hospitals with date of ache at diagnosis. Because we use a 5-year attending aback aeon and because for abounding cancers use of clandestine hospitals for assay is abnormal in New Zealand, we do not anticipate this bent is acceptable to explain the results. About for cancers for which clandestine hospital affliction is added accepted (such as breast and colorectal), we cannot exclude the achievability that the affiliation of lower comorbidity with beforehand date at assay may, at atomic in part, be explained by this effect.
As we did not actual for assorted comparisons in our assay of the absolute role of anniversary of the 42 comorbid altitude on date at diagnosis, alone aplomb intervals for these altitude should be interpreted with caution; however, we accept empiric a bright arrangement of affiliation beyond conditions. Finally, it should be acclaimed that the low prevalence of some alone comorbid altitude is acceptable to accept afflicted our ability to ascertain cogent differences for this basic of the study.
We empiric that accommodating comorbidity (a) increases the allowance of a accommodating actuality diagnosed with abroad metastases, (b) does not advance to beforehand assay and (c) increases the likelihood of a accommodating accepting no date of ache at diagnosis. The backbone of these associations varies by blight type, alone comorbid action and all-embracing comorbidity burden.
The authors acknowledge no battle of interest.
We acknowledge the added C3 (Cancer, Comorbidity and Care) analysis team, and the Bloom Analysis Council of New Zealand for allotment this abstraction (HRC ref #: 10/496). This abstraction was adjourned by the Bloom Analysis Council of New Zealand.
