The Northern Territory Cancer Registry (NTCR) collects data about NT residents who are either diagnosed with cancer or die from cancer. The NTCR analyses and reports the data on cancer epidemiology to provide information for health service planning and delivery and to inform the general public. This report presents summary statistics and trends among NT residents diagnosed with cancer or died due to a cancer-related cause during the various reporting periods. Summary statistics are shown for all new cases of cancer diagnosed during the most recent 10-year period 2001–2010 and all cancer deaths that occurred during the 6-year period 2001–2006. Trends in cancer incidence, mortality and survival are presented for the entire duration of available data; 20 years for incidence and survival trends (1991–2010) and 16 years for mortality trends (1991–2006).

In the Northern Territory (NT) the Northern Territory Cancer Registry (NTCR) collects data about NT residents who are either diagnosed with cancer or die from cancer. The NTCR analyses and reports the data to provide information for health service planning and delivery, as well as for informing the general public. In this report summary statistics are presented on all new cases of cancer diagnosed among NT residents during the 15-year period 1991–2005 and on all cancer deaths during the 13- year period 1991–2003. Equivalent summary statistics for the Australian population are included for comparative purposes. Additionally, for the first time graphical representation of trends in NT cancer incidence and mortality rates are provided for each cancer site. To allow comparison of incidence rates and deaths rates within the NT population and with the wider Australian population, the rates were adjusted for the increase in total populations and for the changing age profile within the populations.

To describe the epidemiology, clinical features, management and outcomes of hepatocellular carcinoma (HCC) in the Northern Territory over the past decade. An NT-wide epidemiology study covering the period 1991-2010 and a clinical cohort study including patients diagnosed during 2000-2011. HCC diagnoses were provided by the NT Cancer Registry and cross-checked against clinical records. Age-adjusted incidence of HCC; management; clinical features; and median and 1-year survival. There were 145 incident cases of HCC in the NT during 1991-2010, giving an age-adjusted annual incidence of 22.7/100 000 (95% CI, 17.2-26.8) for Indigenous Australians and 4.0/100 000 (95% CI, 2.1-5.8) for non-Indigenous Australians - an incidence rate ratio of 5.9 (95% CI, 4.7-7.4). There was no significant change in annual age-adjusted incidence over this period. The most common causative factors were hepatitis B virus in Indigenous people and hepatitis C virus in non-Indigenous people. Most people were diagnosed late, only 13/80 were diagnosed by screening, and outcomes were poor, with 28/80 overall surviving to 1 year. Outcomes were better among those managed through a centralised multidisciplinary service than among those who were not (adjusted hazard ratio for death at 1 year, 0.35 [95% CI, 0.16-0.81]). HCC incidence remains high in the Indigenous people of the NT. More resources are needed for HCC surveillance and management programs in this population.

This report summarises data from the 2003 Northern Territory (NT) Midwives Collection. It includes population characteristics of mothers, maternal health status, antenatal information, conditions and procedures used in labour and childbirth as well as birth outcomes of all births that occurred in 2003. While the NT Midwives’ Collection contains information on both NT resident and interstate residents who gave birth in the NT, the focus of this report is NT residents who gave birth in the NT. Notes and Corrections: On 24 October 2011 an error was observed in table 32. There has been an update to the introduction and to Table 32. An amended version of the document and the previous version are presented below

The Northern Territory (NT) Centre for Disease Control (CDC) undertook contact tracing of all notified cases of coronavirus disease 2019 (COVID-19) within the Territory. There were 28 cases of COVID-19 notified in the NT between 1 March and 30 April 2020. In total 527 people were identified as close contacts over the same period; 493 were successfully contacted; 445 were located in the NT and were subsequently quarantined and monitored for disease symptoms daily for 14 days after contact with a confirmed COVID-19 case. Of these 445 close contacts, 4 tested positive for COVID-19 after developing symptoms; 2/46 contacts who were cruise ship passengers (4.3%, 95% CI 0.5-14.8%) and 2/51 household contacts (3.9%, 95% CI 0.5-13.5%). None of the 326 aircraft passengers or 4 healthcare workers who were being monitored in the NT as close contacts became cases.

To examine trends in caesarean section deliveries and factors associated with these trends for Indigenous and non-Indigenous mothers. Total population-based study. Northern Territory of Australia, 1986-2012. Pregnancies among Northern Territory residents, limited to singleton live births with cephalic presentations delivered at 37-42 weeks' gestation (n = 78 561). Descriptive analyses of demographic and obstetric risk factors. Poisson regression with robust variance to estimate the likelihood of caesarean delivery with and without labour compared with vaginal delivery, over time and between Indigenous and non-Indigenous mothers, adjusting for risk factors. Trends in caesarean sections and risk of caesarean delivery compared with vaginal delivery. The total rate of caesarean deliveries in the Northern Territory increased between 1986 and 2012. From the year 2000, the rise was driven by increases in caesareans with labour among nulliparous mothers and no labour caesareans among multiparous mothers. Increases in demographic and obstetric risk factors explained the rise in caesareans with labour among nulliparous Indigenous mothers, whereas other unmeasured variables contributed to the rise among non-Indigenous mothers. Increases in previous caesarean delivery contributed to the rise in all caesareans among multiparous mothers. Following adjustment, the risk of Indigenous nulliparous mothers having a caesarean with labour was 47% greater than for non-Indigenous nulliparous mothers [adjusted risk ratio 1.47 (95% CI 1.34-1.60)]. Increases in demographic and obstetric risk factors partially explained the increase in caesarean rates in the Northern Territory and the contribution of these factors differed between Indigenous and non-Indigenous mothers. Caesarean section rates increased between 1986 and 2012 in the Northern Territory of Australia.
