Cancer Registration : Principles and Methods 
This volume, which contains 15 authored chapters and four useful appendices, remains a standard reference for those planning to establish new cancer registries and those keen to adopt recognized methodologies. Information is given on the techniques required to collect, store, analyze and interpret data.

Cancer Epidemiology : Principles and Methods 
Chapters include Describing and presenting data, Measures of occurrence of disease and of other health-related events, Overview of study designs, Evaluating the role of chance, Intervention trials, Cohort studies, Case-control studies, Cross-sectional surveys, Routine data-based studies, Introduction to survival analysis, Interpretation of epidemiological studies, How to deal with confounding, Size of a study, Cancer control and prevention, The role of cancer registries, and Planning and conducting epidemiological studies.

ICD-O-3 : International Classification of Diseases (ICD) for Oncology 3rd Ed
- Subset of ICD 10th revision (ICD-10) 
- Specific code set for neoplasms 
- Coding system for primary site and cell type

Coding Multiple Tumours
Multiple tumors are defined differently by various registries, and specific solutions to all problems cannot be given here. 
A working party of IARC recommended definitions of multiple neoplasm for the purpose of incidence reporting for international comparison

AJCC Cancer Staging Manual – TNM System 
The TNM Staging System was developed and is maintained by the AJCC and the Union for International Cancer Control (UICC). It is the most commonly used staging system by medical professionals around the world. The TNM classification system was developed as a tool for doctors to stage different types of cancer based on certain, standardized criteria.
The TNM Staging System is based on the extent of the tumor (T), the extent of spread to the lymph nodes (N), and the presence of metastasis (M).

Summary staging is the most basic way of categorizing how far a cancer has spread from its point of origin. Summary staging has also been called General Staging, California Staging, and SEER Staging. The 2000 version of Summary Stage applies to every anatomic site, including the lymphomas and leukemia. Summary staging uses all information available in the medical record; in other words, it is a combination of the most precise clinical and pathological documentation of the extent of disease.

Cancer control planning without reliable data from cancer registries is prone to misplaced emphasis and wasted investment. This is exactly the position many countries still find themselves in at the beginning of the 21st century. Particularly in low- and middle-income countries, this situation reflects a lack of advocacy for the value of registries, a lack of trained staff and other resources, and a lack of prioritization for “counting cancers” in among the many demands on limited health care services.
