Registration area
Tamil Nadu Cancer Registry Project (TNCRP) is a
collaborative study by the Cancer Institute (W.I.A) and the Department of Health
and Family Welfare (DoH&FW), Government of Tamil Nadu for statewide cancer
surveillance since year 2012. Two government orders viz. [G.O. (Ms.) 132
dated June 17, 2012] and [G.O. (Ms.) 66 dated February
22, 2018] were issued for strengthening TNCRP operations and
declaring cancer as a notifiable disease in Tamil Nadu. TNCRP caters to an
estimated population of 78 million, the largest covered by a single registry in
the world and covers an area of 130,058 km2. The primary objective
of TNCRP is to register all NEW CANCER CASES occurring in the resident
population of Tamil Nadu state in a systematic and continuous manner.
Health systems and oncology facilities
Cancer diagnosis and treatment are provided by
government and private hospitals. The four broad categories of sources of data
on new cancer cases for TNCRP are (i) hospital services, (ii) onco-pathological
services, (iii) other allied services both in government and non-government
sectors and (iv) death certificates in vital statistics division. There are
2,008 sources from where cancer cases have been registered for TNCRP, from the
year 2012 till date.
Registry structure and methods
Case-finding is done both by active and passive
methods. The TNCRP social investigators visited all the potential sources of
data and scrutinized the available medical records or registers for identifying
the cancer cases. The data was abstracted using the TNCRP notification
form. The registry also received data on new cancer patients by
post/email as hard/scanned copies of filled notification forms or
electronically as line-list of data items as per the notification form for
every new cancer patient from data sources having electronic medical record or
computerized patient data. IT IS
RECOMMENDED TO SUBMIT CANCER NOTIFICATIONS TO TNCRP THROUGH THIS ONLINE PORTAL.
Disease coding was done using ICD-O III edition and
ICD-10. Data processing for quality included
case-duplication and consistency checks following international norms.
TNCRP
- Interpreting the results and use of data
TNCRP has evolved over time by stabilizing its
case-finding practices to generate reliable cancer incidence statistics by
gender and age-group for every cancer site in each district for cancer control
action and policy. Cancer incidence
statistics are disseminated by publishing reports. Variable
cancer incidence pattern between urban and rural areas is evident and is
instrumental for in-depth epidemiological investigations by academic
institutions. The TNCRP framework can be utilized for (i) evaluating the ongoing
state-level cancer screening and early detection programs and (ii) delivery of
home-based services for needy cancer patients.
