Introduction: Tobacco products are the major contributors for various cancers and other diseases. In India, tobacco-related cancers (TRCs) contribute nearly half of the total cancers in males and one-fifth in females. Objective: The objective of the study is to investigate 25-year trends and projection of TRCs for 2018–2022. Methods: Joinpoint analysis was performed to assess the trends of TRCs on world age-adjusted rates. Age-period-cohort model with power link function was performed to project the future incidence burden of TRCs in urban Delhi. Results: During the 25 years, a total of 67,129 TRCs (53,125 males and 14,004 females) were registered which was 25.4% of total cancer cases registered. Males contributed 39.1% and females 10.8% of total cases. In males, TRCs declined significantly from 1988 to 2003 with estimated annual percentage change (EAPC) = −0.91% and thereafter increasing trend was observed with EAPC = 3.42%, while in females, the EAPC values were 2.2% and 3.54% respectively for the same period. The total burden of TRCs will be doubled in 2018–2022 with around 46% change due to cancer risk and around 54% due to population age and size in both the genders. The average annual count in males will be 7310 in 2018–2022 as compared to 3571 in 2008–2012 while in females this count will be increased to 2066 from 955 based on recent slope. Conclusion: The incidence of TRCs is increasing due to increase in population age, size, and factors other than population. TRCs are the preventable cancers, and load of these cancers can be controlled with strictly adhering the policy and acts.

Background: There are no studies on the trend of gastric cancer (GC) incidence in Kurdistan, a province in the west of Iran. We aimed to estimate the trend, age-standardized incidence rate (ASR), and annual percentage change (APC) of GC in this province during 2001–2014. Materials and Methods: The data of newly diagnosed GC patients were obtained from the regional Cancer Registering Database. The ASRs were calculated per 100,000 population during 2001–2014. Direct standardization and 95% confidence intervals (CI) were calculated by an efficient method. The temporary changes in ASRs were determined based on the APC by the joinpoint regression model. Results: Overall, 2225 newly diagnosed GC patients were identified. The ASRs ranged from 13.5 (95% CI: 10.4–17.3) to 29.0 (95% CI: 24.5–34.0). The highest ASRs were related to the men and women lived in Divandareh as 32.26 and 13.66, respectively. The respective APC value of GC incidence in women demonstrated a nonsignificant increase during 2001–2008 and a nonsignificant decrease during 2008–2014 (P = 0.1). Accordingly, the incidence of GC in men increased during 2001–2004 (P = 0.1) and decreased during 2004–2014 (P = 0.001). Conclusion: The incidence of GC showed nonsignificant and significant decreasing trends in women and men in Kurdistan province, respectively. Despite such decreasing trends, the Kurdistan province is still considered as one of the regions with high incidence of GC in Iran. Therefore, it is necessary to implement screening programs in the province to early diagnose GC.

Background: Awareness of the trends of cancer incidence in each geographic region is an important. The aim of present study was to determine the incidence trends of cancer in Chaharmahal and Bakhtiari (Ch and B) province in Southwest of Iran. Materials and Methods: In this secondary data analysis, retrospective existing data were used from cancer registry reports in Ch and B in Southwest of Iran in 2003–2016. Data on epidemiologic trend were analyzed using Joinpoint software package and annual percentage change (APC) with 95% confidence interval (95% CI) was computed. Results: Age-standardized incidence rate per 100,000 persons in the province in 2003 was 31.74 that increased to 147.14 in 2016. APC during 2003–2016 was 12.58% (CI: 9.3–16) and significant, which was 10.22% (7.4–13.1) and 14.47% (10.2–18.9) in men and women, respectively. Incidence of the stomach, breast, colorectal, thyroid, lymph node, and ovarian cancers is increasing and the highest incidence was observed in two age groups of 25–34 and 55–64 years. Conclusion: In general, cancers are of increasing trend. Surveillance and monitoring the incidence of cancer and studying the causes of environmental or genetic in the cancer changes can help for cancer prevention and control.
