Epidemiology of cancer in Khyber Pakhtunkhwa (KP), Pakistan, 2020-2023: a retrospective, province-wide, multicentre observational study.
The province of Khyber Pakhtunkhwa (Khyber Pakhtunkhwa), located in the northwestern region, is the third most populous province in Pakistan, with a population estimated at 41 million.
To determine the cancer counts and age-standardised incidence rates (age-standardised incidence rates) per 100 000 population over a 4-year period for Khyber Pakhtunkhwa, 2020-2023, and to compare them with those available for two districts of Pakistan and nearby areas.
Shaukat Khanum Memorial Cancer Hospital and Research Centre in Lahore, as the collaborating centre, with data reported from leading cancer treatment and diagnostic facilities across the country entered into its hospital information system.
The age-standardised incidence rates per 100 000 persons was as follows: in pre-adolescent girls, 4.2; in pre-adolescent boys, 6.6; in adolescent females, 7.9; in adolescent males, 9.7; in adult females, 103.5; and in adult males, 90.1.
In adolescents, the age-standardised incidence rates for leukaemia (0.8-2.0) were high in all three regions, as were those for ovarian cancer (0.8) in Khyber Pakhtunkhwa.
In adults, the age-standardised incidence rates for breast cancer among females were high in Khyber Pakhtunkhwa (32.6) and Lahore (76.7) but very high in Karachi (177.8).
In Khyber Pakhtunkhwa, among children and young adults, haematologic malignancies; in adolescents, bone tumours and ovarian cancers; and in adults, breast and prostate cancers were frequently documented.
There were similarities among the three regions (Khyber Pakhtunkhwa, Lahore and Karachi) in incidence rates. Differences were noted in the top three cancers among males in Khyber Pakhtunkhwa versus Kabul and Iran.
