INCIDENCE AND TRENDS
It is not clear whether withholding or no disclosure of the funding source was the result of either the lack of significant funding or potential conflict of interest. We have included manuscripts published in PubMed only, and other databases are excluded. It also missed some of the data published as government reports and gazettes.[6]
Incidence and trends are studied by Seventy-six papers. uniformity was not found in reporting the incidence rates. The incidence has been reported from the population-based registries and trends from secondary data as ASR and expected annual percentage change. The percentage of patients treated represents the incidence of hospital-based studies. The non-uniformity in reporting and predominance of hospital-based registries lead to misrepresentation of the incidence of cancers and Keeping Journal of Medicine had also revised its rules about conflict of interest.[13 ]
