5 INCIDENCE AND MORTALITY EXECUTIVE SUMMARY In 28-21, 11,33 cases of prostate cancer were diagnosed in the West Midlands, and 2,833 people died of the disease. Prostate cancer is most common in the elderly; very few cancers are diagnosed in the under 5s. Prostate cancer incidence has increased by 7% between 21-3 and 28-1, while mortality rates due to prostate cancer have decreased by 16%. Prostate cancer incidence varies with deprivation; incidence rates are highest in Solihull and lowest in Telford & Wrekin. Mortality rates do not vary significantly across the region. SURVIVAL Prostate cancer survival rates are good compared with other cancers, with 97% of patients surviving 1 year after diagnosis and more than 85% of patients surviving 5 years. Deprivation plays a statistically significant role in 5-year survival following a prostate cancer diagnosis; with 93% of patients in the least deprived group surviving for 5 years compared to 8% in the most deprived group. This may reflect differing uptake of PSA testing in each group. REFERRAL PATTERNS Most prostate cancer patients are diagnosed in Trusts in the cancer network where they live. Prostate cancer patients are referred to each of the five Trusts with radiotherapy facilities. Two Trusts that fall outside the West Midlands also serve patients for whom these Trusts may be geographically closer than those in the West Midlands. TREATMENT The proportion of patients receiving surgical treatment decreases with age and the proportion of patients with no record of treatment rises rapidly with age. For many prostate cancer patients, watchful wait monitoring is appropriate as surgical interventions may confer little additional life-expectancy whilst presenting patients with other life-style complications. The Burton Hospitals NHS Trust had a high proportion of patients who had no treatment recorded and a low proportion of patients receiving surgery. This may be due to the incomplete provision of treatment data for patients who are referred on to out of region Trusts. SURGICAL CASELOAD With the exception of Heart of England NHS Foundation Trust and the Worcestershire Acute Hospitals NHS Trust, the majority of prostate cancer surgery is undertaken by a single lead clinician in most West Midlands Trusts. Ten consultants were recorded as performing fewer than 1 urological resections in 21 in the West Midlands region. STAGE AT DIAGNOSIS Staging data were provided to the WMCIU for only 55% of prostate cancers. The Mid Staffordshire NHS Foundation Trust provided a stage for more than 8% of its patients. TRUST BASED 3-DAY MORTALITY AND SURVIVAL Seven prostate cancer patients died within 3 days of their elective surgical treatment. One, two and five-year relative survival rates following surgery were at or above 1% in the main hospitals where surgery was undertaken. This is likely to be due to the nature of the cohort selected for surgical treatment as well as the efficacy of the treatment. Author: TE/CB/GL Page 1 of 23 Last updated: 2/1/12

6 1. INTRODUCTION 1.1 Prostate Cancer Prostate cancer is the most common cancer in men in England, and after lung cancer is the second most common cause of male cancer death in England 1. This report presents an analysis of prostate cancer incidence, mortality and survival in the West Midlands, together with information on referral and treatment patterns. The majority of invasive malignant cancers of the prostate (ICD-1 code C61) are adenocarcinomas; that is malignant cancers that arise in the cells of glandular tissue. Figure 1.1 illustrates the location of the prostate gland in the male body. Figure 1.1: Anatomical location of the prostate Risk Factors Reproduced courtesy of NHS Choices A number of risk factors are thought to influence the likelihood of an individual developing prostate cancer, but for many the evidence is inconclusive 3. Age, family history and ethnicity are established risk factors. Age is the strongest known causative link with prostate cancer; with risk increasing noticeably in men aged over 5 years. Where there is a family history of prostate cancer, the risk is greater; approximately 5-1% of all prostate cancers are caused by inherited genetic factors 4. If a man has an immediate relative diagnosed with prostate cancer, then the risk of being diagnosed with prostate cancer is 2-3 times greater.

7 3 times greater risk of a prostate cancer diagnosis compared to White men. Asian men have a lower than average risk of developing prostate cancer 5. Though evidence for other risk factors is mixed, foods containing lycopene and selenium are thought to have a protective effect, whilst high levels of calcium consumption may increase the risk of prostate cancer Health Geography in the West Midlands This report covers prostate cancers diagnosed and/or treated within the West Midlands. A document containing information about the Cancer Networks, Local Authorities and acute Trusts providing cancer services in the West Midlands is available on the WMCIU s website 7. For easy reference, a summary of the population characteristics for the top-tier Local Authorities is included in Table 1.1. There are relatively high proportions of people aged over 7 years in Herefordshire and Shropshire (15% and 13% respectively) compared with Birmingham and Telford & Wrekin (1%). The proportion of people with Black and Asian ethnic origin is highest in Birmingham, Wolverhampton and Sandwell (28%, 2% and 19% respectively) and lowest in Herefordshire and Shropshire (1%). Stoke-on-Trent has the highest levels of obesity and smoking (31% and 3% respectively. Obesity levels are lowest in Birmingham (23%) and smoking levels are lowest in Solihull (2%). Birmingham has the highest levels of deprivation in the West Midlands with a deprivation score of.26, while Warwickshire has the lowest level of deprivation in the West Midlands with a deprivation score of.1.

8 Number of cases/ deaths Crude rates per 1, population 2. INCIDENCE AND MORTALITY 2.1 Prostate Cancer Incidence and Mortality in England and the West Midlands There were 11,33 cases of prostate cancer diagnosed in the West Midlands in the 3-year period 28-21, and 2,833 deaths. Prostate cancer mortality rates in the West Midlands are the same as those for England as a whole (23.9 per 1, male population). The incidence data presented for England are the most recent available, and can be used for broad comparisons with the West Midlands data. Prostate cancer agestandardised incidence rates are significantly higher in the West Midlands than in England (17.8 compared to 14.1 per 1, male population). However, as the incidence of prostate cancer is highly dependent on the use of prostate specific antigen (PSA) testing which has changed over time and varies considerably throughout England, comparative data should be interpreted with care.

The number of prostate cancers diagnosed is highest in men aged and 7-74 years. Crude incidence rates peak in males aged at just over 8 cases per 1, males (Figure 2.1). Very few prostate cancers are diagnosed in men aged under 5 years. Deaths due to prostate cancer rise steadily with age; with the numbers of deaths and the crude mortality rate peaking in those age 85 years and over.

9 Age-standardised incidence rate per 1, population Age-standardised incidence rate per 1, population 2.2 Prostate Cancer Incidence Trends in the West Midlands Prostate cancer age-standardised incidence rates have increased significantly from 11 per 1, males (CI 99,13) in to 18 per 1, males (CI 16,11) in (Figure 2.2). Figure 2.2: Prostate cancer incidence trends, West Midlands Dotted lines indicate 95% confidence intervals Diagnosis year 2.3 Variation in Prostate Cancer Incidence with Deprivation Figure 2.3 shows how the incidence of prostate cancer varies with deprivation. Prostate cancer is more common in males in the least deprived quintile; with age-standardised incidence rates 19% higher in males in the least deprived quintile compared with males in the most deprived quintile.

Local authorities are grouped according to cancer network in the order Arden, Greater Midlands, Pan Birmingham and 3-Counties. Prostate cancer incidence was significantly higher in the TTLAs of Solihull, Birmingham, Dudley and Worcestershire compared to the West Midlands average. Significantly lower incidence rates were observed in the TTLAs of Telford & Wrekin, Shropshire, Stoke-on-Trent and Walsall. A number of factors, including levels of deprivation, ethnicity profile and the level of PSA testing undertaken may be the cause of differences in age-standardised incidence rates between TTLAs.

Mortality rates in are significantly lower than those in (24 deaths per 1, males (CI 23, 25) and 28 per 1, males (CI 27, 29) respectively). 2.6 Variation in Prostate Cancer Mortality with Deprivation Figure 2.6 illustrates mortality due to prostate cancer, stratified by deprivation. For the period 28-21, there were no differences in mortality rates between males in the different deprivation quintiles.

12 Coventry Warwickshire Dudley Shropshire Staffordshire Stoke-on-Trent Telford & Wrekin Wolverhampton Birmingham Sandwell Solihull Walsall Herefordshire Worcestershire Mortality/incidence rate ratio 2.8 Prostate Cancer Mortality/Incidence Rate Ratios in the Top Tier Local Authorities The relationship between the mortality and incidence of a disease can be measured with reference to mortality incidence ratios (M:I) for cases occurring in equivalent time periods. For cancers typically characterised by short-term survival, for example lung and liver cancer, a M:I ratio of close to one is not unusual. In contrast, for breast and prostate cancer where survival is usually very good, M:I ratios are generally much lower than one. In rare situations, M:I ratios of greater than one are observed; this is likely to reflect under-recording of new cases, and/or inaccurate mortality statistics 8. Figure 2.8 shows the mortality/incidence ratio for prostate cancers in top tier Local Authorities in Telford & Wrekin and Shropshire had significantly higher mortality incidence ratios compared to the West Midlands. This is due to the significantly low incidence rates in these TTLAs (Telford & Wrekin has the lowest incidence in the whole of the West Midlands), and the slightly higher than average mortality rates. Solihull had a significantly lower mortality/incidence ratio, explained by its significantly high incidence and lower than average mortality rate (Solihull had the lowest mortality rate in the West Midlands). A number of factors, including level of deprivation, ethnicity profile, the level of PSA testing undertaken and tumour stage at presentation may be the cause of differences in incidence and mortality rates between TTLAs. The lower than average mortality/incidence ratio in Solihull may be related to high levels of PSA testing in this relatively affluent TTLA.

13 Relative survival rate 3. SURVIVAL 3.1 Trends in Survival in the West Midlands Figure 3.1 shows one-, five- and ten-year relative survival rates for prostate cancer in the West Midlands. Survival from a prostate cancer diagnosis is usually very high and has been rising since the mid 199s. One-year relative survival has risen significantly from 89% for cases diagnosed in to 97% for cases diagnosed in Five-year relative survival has risen more rapidly from 67% in cases to 85% in cases. Ten-year relative survival has also increased significantly from 57% in to 63% in Prostate cancer survival in the West Midlands Figure 3.1: Prostate cancer survival trends, West Midlands, males Dotted lines indicate 95% confidence intervals 1% 8% 6% 4% 2% % Diagnosis year One-year relative survival Five-year relative survival Ten-year relative survival Increases in survival are likely to reflect the effects of earlier detection, in particular the use of PSA testing, and are perhaps less reflective of significant improvements in treatment. However, prostate cancer mortality rates have fallen since 21-23, indicating either that some advancement in treatment has occurred, in particular the targeted use of radiotherapy, or improvements in the stage at diagnosis through earlier presentation Variation in Prostate Cancer Survival with Deprivation Figure 3.2 shows how one- and five-year relative survival rates for prostate cancer vary with deprivation. Although one-year relative survival rates were higher in males in the least deprived quintile, the differences in survival between deprivation quintiles were not significantly different. Five-year relative survival following a prostate cancer diagnosis is significantly higher in men in the least deprived quintile than in those in the most deprived quintile (93% compared to 8%). This may reflect higher levels of PSA testing uptake by more affluent men resulting in an earlier diagnosis. Author: TE/CB/GL Page 9 of 23 Last updated: 2/1/12

15 Trust first seen 4. REFERRAL PATTERNS 4.1 Referral Patterns to Acute Trusts In order to obtain the Trust first seen, with the exception of death certificate only registrations, all prostate cancer patients (n=11,221) in the cancer registration cohort were matched to Cancer Waiting Times (CWT) data. Where a match to CWT data was not possible a Trust first seen was assigned using the earliest record at an acute Trust or private hospital in the cancer registration data. Any information relating to a Trust first seen in CWT data that preceded the cancer registration data by more than 12 months was discarded. Date differences of more than 3 days were only accepted where a definitive ICD-1 code match was possible between both datasets. Where a patient had a single cancer diagnosis on the cancer registration database and a single occurrence in CWT data within 3 days of diagnosis, the rules for direct ICD-1 matching were relaxed. Of the 11,221 prostate cancers in the original cancer registration cohort, 3,856 (34%) could not be matched to CWT data. Of the 7,365 tumours that could be matched, 97% (n=7,145) shared the same Trust first seen in both data sources. This methodology may introduce some bias towards the tertiary Trusts where surgery was undertaken if imaging or other clinical data have not been not submitted to the WMCIU by the Trusts where the patients was first referred. However, the good agreement between datasets when matches were possible should be noted. Prostate cancer patients were referred to all of the main acute Trusts in the region, though the number of tumours diagnosed in each Trust varied widely. The Burton Hospitals NHS Foundation Trust (BH) diagnosed the smallest number of prostate cancers in West Midlands residents (although it also saw out of region patients), while the Heart of England NHS Foundation Trust (HEFT) diagnosed the largest number of prostate cancers (over 1,6 in 3 years).

The Trusts with the most diverse referral patterns were The Dudley Group of Hospitals NHS Foundation Trust (DGH), The Royal Wolverhampton Hospitals NHS Trust (RWH), the Heart of England NHS Foundation Trust (HEFT), the Sandwell & West Birmingham Hospitals NHS Trust Author: TE/CB/GL Page 11 of 23 Last updated: 2/1/12

16 Trust first seen (SWBH) and the University Hospital Birmingham NHS Foundation Trust (UHB). These Trusts each diagnosed cases from at least 7 TTLAs. 4.2 Referral Patterns of Trust First Seen to Trust of Radiotherapy Five Trusts within the West Midlands region have Linear Particle Accelerators (LINACs) and provide radiotherapy treatment. West Midlands patients who live close to the region s boundaries are also referred to the Derby Hospitals NHS Foundation Trust (DHFT) and the Gloucestershire Hospitals NHS Foundation Trust (GH) for radiotherapy treatment. The University Hospital Birmingham NHS Foundation Trust (UHB) had the most referrals from other Trusts for radiotherapy treatment (n=778). The majority of these were from Heart of England NHS Foundation Trust (HEFT) and the Sandwell & West Birmingham Hospitals NHS Trust (SWBH) due to the proximity of these Trusts to the UHB. The Worcester Acute Hospitals NHS Trust (WAH) refers patients to three different radiotherapy centres, reflecting the geographical area that the Trust covers, with hospitals in the Arden, 3 Counties and Greater Midlands Cancer Networks. The Gloucester Hospitals NHS Foundation Trust (GH) received referrals from the Wye Valley NHS Trust (WV) and the Worcester Acute Hospitals NHS Trust (WAH). Treatment at the Gloucester Hospitals NHS Foundation Trust (GH) is likely to be phased out for some patients from 213 when a new radiotherapy unit is opened at the Wye Valley NHS Trust (WV). Figure 4.2: Referral patterns from Trust first seen to Trust of radiotherapy, GEH SW BH DGH MSH HEFT SWBH WH WV Trust of radiotherapy UHCW STH RWH UHNS UHB DHFT GH WAH Number of tumours referred to Trust of radiotherapy 5. TREATMENT 5.1 Types of Treatment For many prostate cancers, no radical treatment is necessary as the growth of the disease is indolent. As a result, many patients will undergo a programme of watchful waiting, whereby the development of the disease is monitored to ensure it does not evolve into a fast-growing tumour. When prostate cancer treatment is applicable, the main aims are to either control or cure the disease, with specific reference to minimising the day-to-day side effects of the disease. The main treatments for prostate cancer include surgery, radiotherapy and hormone therapy. Author: TE/CB/GL Page 12 of 23 Last updated: 2/1/12

17 Age group 5.2 Prostate Cancer Treatment Patterns Variation in Prostate Cancer Treatment with Age Figure 5.1 shows that the proportion of tumours treated with surgery decreases with age, while the proportion of patients receiving no treatment rises with age; 39% of patients aged 5-59 years received surgery compared with 25% of patients aged 6-69 years and only 6% of patients aged 7-79 years. Care should be taken in the interpretation of the data for the youngest age group as there are only 11 cases in the -49 year age group (see Figure 2.1). Hormone therapy as the only treatment increases with age and is likely to be palliative in intent. This treatment is most common in men aged 8 years and above (25% in men aged 7-79 years compared with 13% and 8% in men aged 6-69 years and 5-59 years respectively). These older patients may have co-morbid conditions and the side effects of surgery, which may be difficult for the patient to tolerate, may confer little additional benefit in terms of life-expectancy for the patient. Figure 5.1: Treatment patterns for all prostate cancer cases by age, diagnosed All % 1% 2% 3% 4% 5% 6% 7% 8% 9% 1% Percentage of tumours Surgery only Surgery & adjuvant therapy Hormone therapy only Radiotherapy only Radiotherapy & hormone therapy Adjuvant therapies No treatment - active monitoring No treatment -no active monitoring A large proportion (36%) of prostate cancers registered by the WMCIU had no record of having received treatment. Although this is in line with guidance suggesting that no active treatment is an option for many prostate cancer patients, it could mask poor data quality provision to the WMCIU since 53% of these cancers could not be verified via CWT data as being actively monitored Variation in Prostate Cancer Treatment with Deprivation Figure 5.2 shows how the combinations of treatment given to prostate cancer patients vary with deprivation. Treatment patterns are similar for all patients regardless of levels of deprivation, suggesting that the deprivation status of the patient is not influencing treatment decisions. Although a higher proportion of prostate cancers diagnosed in men in the least deprived quintile received surgery when compared to men in the most deprived quintile (17% compared with 13%), this difference was not statistically significant.

Reasons for this are complex. There may be true variation in treatment provided, which may be clinically relevant due to variation in case-mix. There may also be variation in the quality of data sent to the WMCIU by different Trusts.

The majority (67%) of the patients included in this category were treated Author: TE/CB/GL Page 14 of 23 Last updated: 2/1/12

19 Top tier local authority in private hospitals. The Burton Hospitals NHS Trust (BH) has a high proportion of prostate cancer patients who did not have any treatment recorded. This may be due to the incomplete provision of treatment information for patients who are referred on to out of region Trusts. The Shrewsbury & Telford NHS Trust (STH) provided surgery, hormone therapy and/or radiotherapy treatment to 81% of patients first seen there. This is the highest proportion in the region and substantially higher than the regional average of 64%. The proportion of patients receiving active monitoring alone in this Trust was substantially lower than the regional average (5% compared with 17%) Treatment in Each Top Tier Local Authority Figure 5.4 shows that higher proportions of residents of the Shropshire, Telford & Wrekin and Walsall TTLAs received surgery, hormone therapy and/or radiotherapy treatment for their prostate cancer compared to the West Midlands average. These results are consistent with the relatively high proportions of treatment recorded at the Shrewsbury & Telford NHS Trust (STH) and the Walsall Healthcare NHS Trust (WH) (Figure 5.3).

SURGICAL CASELOAD 6.1 Trust Caseload In 21, 584 prostate cancer patients had a surgical resection (Table 6.1). 85% of these were known to be elective operations and 2 were known to be elective. The admission status for 86 patients was not recorded. However, as 53 (62%) of these operations took place in private hospitals, they can be assumed to have been elective which increases the regional average to 94%. The admission status of 28% of the resections undertaken at The Dudley Group of Hospitals NHS Foundation Trusts was unknown because the cancers could not be matched to HES. 24% of all prostate cancer patients in the West Midlands had their surgical resection at the Heart of England NHS Foundation Trust (HEFT). 91% of these operations were known to be elective.

These caseload data relate to surgical procedures for urological cancers for which the intent of the operation was thought to be curative. Trust level data in this table cannot be directly compared with those in Table 6.1 as some consultants operate in more than one Trust. Thirty four consultant surgeons were recorded by the WMCIU as having operated on 584 prostate cancer patients during 21. The total number of curative operations performed on patients with a urological cancer was 1,75.

21 prostate cancer operation in 21. Of these, 7 undertook fewer than 1 curative operations on urological cancer patients. The outside region caseload of the three outside region surgeons in Table 6.2 is not known. Most Trusts had at least one consultant who carried out more than 17 prostate cancer operations; the exceptions being the Burton Hospitals NHS Foundation Trust (which is believed to refer patients to an outside region Trust for surgery) and the Wye Valley NHS Trust. In the Heart of England NHS Foundation Trust (HEFT) all four consultants operated on 28 or more prostate cancer patients in 21. The Worcestershire Acute NHS Trust (WAH) also had a high degree of surgical specialisation with two consultants carrying out 36 or more prostate cancer operations in 21.

22 Trust first seen 7. STAGE AT DIAGNOSIS The stage at which prostate cancer is diagnosed is inextricably linked to the treatment provided and to patient outcome; with early stage tumours having better outcomes than late stage tumours. 7.1 Histological Confirmation of Prostate Cancer The benefit of having histological confirmation for a cancer is that the tumour characteristics (such as grade, size, and stage) can be accurately verified. This enables a more accurate and targeted treatment plan for the patient to be developed. In the West Midlands, 89% of prostate cancers were histologically verified in 21. Four Trusts, (University Hospital of North Staffordshire NHS Trust (UHNS), Worcestershire Acute Hospitals NHS Trust (WAH), University Hospitals Coventry & Warwickshire NHS Trust (UHCW) and Royal Wolverhampton Hospitals NHS Trust (RWH)) had histological confirmation rates below the West Midlands average.

TNM stage for prostate cancer is incompletely recorded on the WMCIU s cancer registration database; with the stage at diagnosis being unknown for 45% of cases in 21. This is mainly due to the limited provision by Trusts of clinical TNM stage and imaging data to the WMCIU which means that only the T and N components of the TNM stage are known. Figure 7.2 shows the TNM Stage completeness for each Trust first seen. Four Trusts (University Hospitals Coventry & Warwickshire NHS Trust (UHCW), The Dudley Group NHS Foundation Trust (DGH), Walsall Healthcare NHS Trust (WH) and George Eliot Hospital NHS Trust (GEH)) had particularly low proportions of prostate cancers with a TNM stage. There were no Stage I cancers recorded in 21. Stage I cancers are often diagnosed incidentally during other procedures, for example investigation of the bladder. Diagnosis of prostate cancer is usually directly linked to a person presenting with symptoms or high PSA levels which are unlikely to occur in patients with Stage I tumours.

Using these combined data, 55% of prostate cancers diagnosed in the West Midlands in 21 could be assigned an overall TNM stage and 29% a partial TNM stage. Approximately 16% of cases could not be assigned a partial or overall TNM stage.

24 Trust of surgery Number of surgical resections applying internal algorithms. The main reason for the good staging information received from this Trust is the standardised and simplified reporting format used which allows for easy transfer of data to the WMCIU. Much of the good prostate cancer staging data recorded for Trusts in 21 can be attributed to the efforts that WMCIU staff have made in undertaking visits to Trusts to obtain staging data from patient files and electronic patient records directly rather than being reliant upon the data being provided. 8. TRUST-BASED 3-DAY MORTALITY AND SURVIVAL day Post Operative Mortality Thirty-day post operative mortality following surgical resection to the prostate for cases diagnosed between in the West Midlands was very good. Only 7 patients died within 3-days of their elective surgical procedure. Approximately 3% of patients who underwent a surgical resection between had subsequently died by 31/12/211. Figure 8.1 shows 3-day post-operative mortality rates following a surgical resection to the prostate in Trusts of the West Midlands that undertook surgical resections in the 3-year period 28 to 21, the total number of surgical resections undertaken for the treatment of prostate cancer in each Trust is given to the right of the Figure 8.1. Of the seven deaths to occur within 3- days of elective surgery, five were patients who underwent surgical treatment for bladder cancer and in each case a cystoprostatectomy was performed. Following the removal of both the bladder and the prostate, a prostate cancer was diagnosed incidentally in each of these patients.

27 THE WEST MIDLANDS CANCER INTELLIGENCE UNIT The WMCIU houses a cancer registry serving the approximate 5.4 million residents in the West Midlands. The registry holds records dating back to 1936 and has been population based since All malignant neoplasms of invasive, in-situ, uncertain or unknown behaviour and a limited number of benign tumours of the brain and CNS are recorded on the WMCIU s central database. Over 37, new tumours were registered in 21 of which approximately 29, relate to invasive malignant neoplasms 9. The database now holds in excess of 1.2 million records. Data are acquired from a variety of sources, including hospitals, cancer centres, treatment centres, hospices, private hospitals, cancer screening programmes, other cancer registries, general practices, nursing homes and death certificates. The WMCIU aims to register each case from a range of data sources to ensure the most accurate information possible full coding of a cancer case may involve data from hospital patient information systems, pathology reports, medical records departments, radiotherapy systems and death certificates. The WMCIU has in recent years increased its activity of receiving electronic cancer registration data and utilising automated methods of processing this data. A preliminary registration is recorded on the WMCIU database within 3 months of receiving the data. Full clinical coding of the case takes place within 12 months of the preliminary registration, within which time the registry expects to have received all relevant information relating to the patient. The WMCIU collects a wide range of data items, including: Patient demographics Tumour details Treatment modality Death details The records are clinically coded by experienced registrars trained to UK Association of Cancer Registries (UKACR) standards, who use internationally recognised ICD1 topography, ICDM morphology and OPCS4 procedure codes. All data inputted to the database is subjected to a detailed quality assurance process, and the data are available for detailed analysis 14 months after the end of the calendar year to which they relate. The WMCIU aims to deliver timely, comparable and high quality cancer data to a range of stakeholders. The core information team undertakes a range of analyses to support this aim. These include: Monitoring trends in cancer incidence, mortality and survival Evaluating the quality and outcomes of cancer care Supporting the work of cancer genetic counselling services Providing data for and working with academic researchers Planning and monitoring the efficacy and cost effectiveness of the diagnostic and therapeutic services provided to cancer patients Monitoring performance against key standards. 9 Non melanoma skin cancers are excluded from the count of malignant invasive tumours as they are often treated in primary care; therefore case ascertainment is incomplete.
