Ovarian cancer incidence rates have remained stable since the early 1990s, UK

Ovarian cancer is the 6th most common cancer in females in the UK, accounting for 4% of all new cancer cases in females (2015).[1-4]

Ovarian cancer incidence rates (European age-standardised (AS) rates Open a glossary item ) are similar to the UK average in all the UK constituent countries.

Ovarian cancer incidence is strongly related to age, with the highest incidence rates being in older women. In the UK in 2013-2015, on average each year more than a quarter (28%) of new cases were in females aged 75 and over.[1-4] 

Age-specific incidence rates rise steadily from around age 30-34 and more steeply from around age 45-49, with a sharp drop in the oldest age groups. The highest rates are in the 75 to 79 age group.

For ovarian cancer, like most cancer types, incidence increases with age. This largely reflects cell DNA damage accumulating over time. Damage can result from biological processes or from exposure to risk factors. A drop or plateau in incidence in the oldest age groups often indicates reduced diagnostic activity perhaps due to general ill health.

Over the last decade in the UK (between 2003-2005 and 2013-2015), ovarian cancer AS incidence rates for females decreased by 5%.[1-4]

Ovarian Cancer (C56-C57.4), European Age-Standardised Incidence Rates, Females, UK, 1993-2015

Ovarian cancer incidence rates have increased overall in some broad age groups in females in the UK since the early 1990s, but have decreased in others.[1-4] Rates in 0-24s have increased by 83%, in 25-49s have increased by 11%, in 50-59s have decreased by 15%, in 60-69s have decreased by 10%, in 70-79s have increased by 9%, and in 80+s have increased by 12%.

For ovarian cancer, like most cancer types, incidence trends largely reflect changing prevalence of risk factors and improvements in diagnosis and data recording. Recent incidence trends are influenced by risk factor prevalence in years past, and trends by age group reflect risk factor exposure in birth cohorts.

Overall stage at diagnosis

A high proportion (85-88%) of ovarian cancer cases in England and Northern Ireland have stage at diagnosis recorded.[1,2]

More females with a known stage are diagnosed at a late stage (55-58% are diagnosed at stage III or IV), than an early stage (42-45% are diagnosed at stage I or II). Between 17% and 21% of females have metastases at diagnosis (stage IV).[1,2]

The stage distribution for each cancer type will reflect many factors including how the cancer type develops, the way symptoms appear, public awareness of symptoms, how quickly a person goes to see their doctor and how quickly the cancer is recognised and diagnosed by a doctor. It might also relate to whether a national screening programme that can detect early stage disease exists for that cancer type, along with the extent of uptake of that programme.

A cancer type associated with a large proportion of early stage diagnoses could be one that is more likely to be symptomatic at an earlier stage of development, with recognisable symptoms rather than more generic ones.

Ovarian Cancer (C56), Proportion of Cases Diagnosed at Each Stage, All Ages, England 2014 and Northern Ireland 2010-2014

Data should not be compared between countries due to differences in time periods and possible differences in recording of stage at diagnosis.
 

Stage at diagnosis by deprivation

Late stage at diagnosis of ovarian cancer is not associated with deprivation in England.[3]

Stage at diagnosis by age

Late stage at diagnosis of ovarian cancer is more common in women aged 80+ in England (77% diagnosed at stage III or IV), compared to those aged 60-79 (66% diagnosed at stage III or IV) and compared to younger women aged 15-59 (39% diagnosed at stage III or IV).[3]

Late stage ovarian cancer is also more common in women aged 60-79 in England (66% diagnosed at stage III or IV) versus those aged 15-59 (39% diagnosed at stage III or IV).[3]

These patterns by deprivation, age and sex are probably not explained by other demographic differences.[4]

About this data

Data is for:  England 2014, Northern Ireland 2010-2014, ICD-10 C56 (overall stage at diagnosis) and England, 2012-2013, ICD-10 C56-C57 (stage at diagnosis by deprivation, age, sex, and ethnicity)

Data is not comparable between countries due to differences in time periods and possible differences in how countries record stage at diagnosis.

The proportions of patients diagnosed late only include cases with a known stage at diagnosis and are not adjusted for other demographics differences (e.g. age, sex, ethnicity) unless stated otherwise.

80-90% of ovarian malignancies are epithelial  in origin, with the most common type in the UK being serous carcinomas.[1-3] Other rarer subtypes include germ cell tumours Open a glossary item, which tend to occur in pre-menopausal women and are very chemo-sensitive (and hence treatable). It is thought that most histologies share common risk factors, with the probable exception of mucinous carcinomas.[1,4]

The most striking international difference occurs in Japan, which has lower rates of ovarian cancer than in Europe.[5] Some of this variation may be explained by geographical differences in histologies, since Japan has a higher percentage of clear cell adenocarcinomas Open a glossary item (20-25%) compared with other Asian or Western countries (5-10%).[6]

About this data

Data is for: UK, 1979-2014 (observed), 2015-2035 (projected), ICD-10 C56-C57.4

Projections are based on observed incidence and mortality rates and therefore implicitly include changes in cancer risk factors, diagnosis and treatment. It is not possible to assess the statistical significance of changes between 2014 (observed) and 2035 (projected) figures. Confidence intervals are not calculated for the projected figures. Projections are by their nature uncertain because unexpected events in future could change the trend. It is not sensible to calculate a boundary of uncertainty around these already uncertain point estimates. Changes are described as 'increase' or 'decrease' if there is any difference between the point estimates.

About this data

Deprivation gradient statistics were calculated using incidence data for 2006-2010. The deprivation quintiles were calculated using the Income domain scores from the Index of Multiple Deprivation (IMD) from the following years: 2004, 2007 and 2010.

Age-standardised Open a glossary item rates for White females with ovarian cancer (ICD-10 C56 only) range from 17.4 to 18.1 per 100,000.

Ranges are given because of the analysis methodology used to account for missing and unknown data. For ovarian cancer, 28,023 cases were identified; 22% had no known ethnicity.
