Introduction

This document is being released to expand on information contained in the publication Cancer: New registrations and deaths 2008, which was released by the Ministry of Health in May 2011. Recent Ministry publications relating to cancer can be accessed from the Ministry of Health’s website at:

The Cancer: New registrations and deaths 2008 publication contains a chapter detailing cancer registrations and deaths by District Health Board (DHB) region of residence. It provides information on total cancer registrations and total cancer deaths. This report presents an expanded version of that information. In addition to total rates of cancer registration and death by DHB region, four individual cancer sites are also shown:

• lung cancer

• colorectal cancer

• prostate cancer

• breast cancer in females.

These sites were chosen as they were some of the most commonly registered cancers in 2008, and also had high enough mortality figures to enable robust calculations to be produced. Data for 2006, 2007 and 2008 was aggregated to minimise the effects of year-on-year variance in the data.

This document uses age-standardised rates to compare cancer registration and death information for patients residing in different DHB regions. Age-standardised rates were used as they adjust for differences in age distribution of the populations being compared and allow comparison to be made between differing groups, in this instance between DHB regions (see Explanatory notes).

Confidence intervals were also calculated to enable the significance of any differences between rates by DHB region and the New Zealand rate to be assessed (see Explanatory notes).

Information in this report is presented in two ways.

• Maps show varying shades to distinguish between DHB regions that have significantly higher or lower rates than the national rate.

• The same data is also displayed in charts showing the actual calculated rate for each DHB region of domicile and the confidence intervals surrounding it.

This report does not attempt to interpret any observed differences in rates between DHB regions. The information has been released to provide a description of the available data and to promote further discussion.

Ethnicity and Deprivation

Although the use of age-standardised rates adjusts for differences in age structures between DHB regions, none of the information in this report has been adjusted to account for differences in either ethnicity or deprivation.

Different DHB regions show different proportions of Māori in their populations, and because Māori tend to exhibit higher rates of cancer, this will affect rates of registration and death to some extent.

Different DHB regions also show different levels of socioeconomic deprivation, which has been associated with various health outcomes, and those who are most deprived generally experience poorer health (White et al 2008; Benzeval et al 2001).

It is therefore important to consider the differences in population structure when reading this report. Figure 1 shows the different proportions of Māori in the DHB region populations. Figure 2 shows the patterns of deprivation across New Zealand by domicile code (see Explanatory notes) and also shows the DHB region boundaries.

Other aspects that should be taken into account when considering differences between DHB regions include rurality and access to treatment, possible hereditary biases in populations, and the fact that the rate shown in each case is the rate for that region and not that of all the individuals within it.

Total Cancer Registrations and Deaths (ICD* codes C00–96 and D45–D47)

Registrations

Figure 3 is a map of New Zealand showing total cancer registration rates by DHB region using 2006, 2007 and 2008 aggregated data. The varying shades shown on the map distinguish between DHB regions that have significantly higher or lower registration rates than the New Zealand rate.

• Controlling for the differing age structures within each DHB region, patients living in four regions had age-standardised cancer registration rates that were significantly higher than the national rate (Northland, Bay of Plenty, Lakes and Canterbury).

• Six regions had registration rates that were significantly lower than the national rate (Counties Manukau, Capital & Coast, Wairarapa, Hutt Valley, Otago and Southland).

• All of the other remaining DHB regions had rates with 95 percent confidence limits that overlapped with the New Zealand registration rate, meaning that, statistically speaking, they were no different from the national rate.

The same data is shown in Figure 5, showing the calculated age-standardised rate and the spread of the confidence intervals for each DHB region.

Deaths

Figure 4 is a map of age-standardised total cancer mortality rates by DHB region for the years 2006–2008. Again, the varying shades show regions with significantly higher or significantly lower rates of death than the national rate.

• The map shows that patients living in eight regions had age-standardised cancer mortality rates that were significantly higher than the national rate (these regions were mostly centred around the middle and upper North Island, with the exception of Otago DHB).

• Four DHBs had mortality rates that were significantly lower than the national rate (Waitemata, Auckland, Capital & Coast and Canterbury).

Figure 6 shows the same death information shown in Figure 4. The confidence intervals in this figure are broader than those seen in the corresponding registrations information (Figure 5) due to the lower numbers of deaths resulting in greater variability within the data.

* Note: The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM) Third Edition was used to classify the registration data used in this report. The Second and Sixth Editions of the same publication were used to classify the mortality data used in this report. More information is in the Cancer: New registrations and deaths 2008 publication, which can be found at: .

Lung Cancer Registrations and Deaths

(ICD codes C33–34)

Registrations

Cancer of the trachea, bronchus and lung (lung cancer) was the fifth most common cancer to be registered in 2008, accounting for 9 percent of all cancer registrations.

• Figure 7 shows that patients living in four DHB regions had lung cancer registration rates that were significantly higher than the New Zealand rate (Northland, Lakes, Counties Manukau and Tairawhiti).

• Two DHB regions (Nelson Marlborough and Canterbury) had rates that were significantly lower.

The same data is shown in Figure 9, but includes the age-standardised rate and shows the spread of the confidence intervals for each DHB region.

Deaths

Lung cancer accounted for 19 percent of all deaths from cancer in 2008 and was the leading cause of cancer death in that year.

• Figure 8 shows the rates of death from lung cancer, and exhibits a very similar pattern to that seen for registrations in Figure 9. All but three DHB regions showed the same significance grouping for cancer death as they did for registrations.

• Waikato and Whanganui DHB regions had higher rates of death but registration rates that were not significantly different from the national rate.

• Waitemata DHB region had a lower rate of death but a registration rate that was not statistically different from the national rate.

Figure 10 shows the same death information as Figure 8 in the form of a chart.

Colorectal Cancer Registrations and Deaths

(ICD codes C18–C21)

Registrations

Cancer of the colorectum and anus (colorectal cancer) was the second most common cancer to be registered in 2008, constituting 14 percent of all cancer registrations.

• Figure 11 is a map of colorectal cancer registration rates. It shows that patients residing in the three most southerly DHB regions exhibited significantly higher registration rates than the New Zealand rate.

• Waitemata, Counties Manukau, Tairawhiti, Capital & Coast and Hutt Valley DHB regions had registration rates that were significantly lower than the national rate.

The same data is shown in Figure 13, but includes the age-standardised rate and shows the spread of the confidence intervals for each DHB region.

Deaths

Colorectal cancer was the second most common cause of cancer deaths in 2008 (15 percent of all deaths from cancer).

• Figure 12 shows that the three most southerly DHB regions had significantly higher rates of death from colorectal cancer (as was true for registrations). In addition, Waikato DHB region had a mortality rate that was significantly higher than the national rate.

• Only patients residing in Waitemata DHB region showed a colorectal cancer mortality rate that was significantly lower than the national rate.

The information in Figure 12 is replicated in Figure 14 as a chart.

Prostate Cancer Registrations and Deaths

(ICD code C61)

Registrations

Prostate cancer was the most common cancer to be registered in 2008, both within the total population and for males. This cancer accounted for 28 percent of all male cancer registrations in 2008.

• Figure 15 is a map of prostate cancer registration rates. It shows that five DHB regions had registration rates that were significantly higher than the national rate (Northland, Waitemata, Whanganui, Nelson Marlborough and Canterbury).

• Patients residing in Taranaki, Wairarapa, South Canterbury, Otago and Southland DHB regions had rates that were significantly lower than the New Zealand rate.

The same data is shown in Figure 17, but includes the age-standardised rate and shows the spread of the confidence intervals for each DHB region.

Deaths

Prostate cancer was the third most common cause of cancer death in men in 2008 and accounted for 15 percent of male cancer deaths in that year.

• Figure 16 shows that there were no DHB regions with prostate cancer mortality rates significantly higher than the national rate.

• Patients who lived in Waitemata, Auckland, and Capital and Coast DHB regions had rates of death from prostate cancer that were significantly lower than the national rate.

Figure 18 shows the same mortality information as Figure 16, in the form of a chart.

Female Breast Cancer Registrations and Deaths

(ICD code C50)

Registrations

Breast cancer was the most common cancer to be registered for women (accounting for 28 percent of all female cancer registrations) in 2008.

• Figure 19 is a map of female breast cancer registration rates. It shows that only two of the 21 DHB regions had rates that were different from the national rate.

• Only Waitemata DHB region had a rate that was higher than the national rate.

• The Nelson Marlborough DHB region had a rate that was significantly lower than the national rate.

The same data is shown in Figure 21, but includes the age-standardised rate and shows the spread of the confidence intervals for each DHB region.

Deaths

Breast cancer was the second most common cause of cancer death in women in 2008 (accounting for 15 percent of female cancer deaths).

• Figure 20 shows that only one DHB region (Taranaki) showed a female breast cancer mortality rate that was significantly higher than the national rate.

• Patients residing in the Northland region showed a rate of death that was significantly lower than the national rate.

Figure 22 shows the same mortality information as Figure 20, in the form of a chart.

Explanatory Notes

General information relating to cancer data collection

For information relating to the New Zealand Cancer Registry, disease coding, timeliness of data and relevant legislation, please see the Explanatory notes in the Cancer: New registrations and deaths 2008 publication, which can be found on the Ministry of Health’s website:

Rate calculations

Age-specific rates show the number of events (for example, cancer registrations or deaths) per 100,000 of the population in each age group.

Age-standardised rates adjust for differences in age distribution of the populations being compared. They are calculated by the direct standardisation method, which multiplies the age-specific rates by a standard population. The standard population used in this publication is the World Health Organization (WHO) world standard population.

Confidence intervals

The confidence intervals in this publication have been calculated using the methods presented in Keyfitz (1966).

A confidence interval is a range of values used to describe the uncertainty around a single value (such as an age-standardised rate). Confidence intervals describe how different the estimate could have been if chance had led to a different set of data. Confidence intervals are calculated with a stated probability, typically 95 percent (which would indicate that there is a 95 percent chance that the true value lies within the confidence intervals).

Deprivation

The New Zealand Social Deprivation Index is a measure of socioeconomic status calculated for small geographic areas. The calculation uses a range of variables from the 2001 and 2006 Census of Population and Dwellings, which represent nine dimensions of social deprivation. The Social Deprivation Index is calculated at the level of meshblocks (geographical units containing a median of 90 people), and the Ministry of Health maps these to domicile codes, which are built up to the relevant geographic scale using weighted average ‘usually resident population’ counts from the Census. The nine variables (proportions in small areas) in the index, by decreasing weight, are:

• income: people aged 18 to 59 receiving a means-tested benefit

• employment: people aged 18 to 59 who are unemployed

• income: people living in an equivalised household whose income is below a certain threshold

• communication: people with no access to a telephone

• transport: people with no access to a car

• support: people aged under 60 living in a single-parent family

• qualifications: people aged 18 to 59 with no qualifications

• living space: people living in an equivalised household below a bedroom occupancy threshold

• owned home: people not living in their own home.

Domicile

Domicile codes used for health collections are four-digit Health Domicile Codes. These codes are based on geographic areas and were created by Statistics New Zealand from its six-digit Census Area Unit Codes. From 2006 to 2008, the Health Domicile Codes used are based on the 2001 Census Area Unit Codes.
