Policymakers require estimates of the future number of cancer patients in order to allocate finite resources to cancer prevention, treatment and palliative care. We examine recent cancer incidence trends in Iran and present predicted incidence rates and new cases for the entire country for the year 2025. We developed a method for approximating population‐based incidence from the pathology‐based data series available nationally for the years 2008 to 2013, and augmented this with data from the Iranian National Population‐based Cancer Registry (INPCR) for the years 2014 to 2016. We fitted time‐linear age‐period models to the recent incidence trends to quantify the future cancer incidence burden to the year 2025, delineating the contribution of changes due to risk and those due to demographic change. The number of new cancer cases is predicted to increase in Iran from 112 000 recorded cases in 2016 to an estimated 160 000 in 2025, a 42.6% increase, of which 13.9% and 28.7% were attributed to changes in risk and population structure, respectively. In terms of specific cancers, the greatest increases in cases are predicted for thyroid (113.8%), prostate (66.7%), female breast (63.0%) and colorectal cancer (54.1%). Breast, colorectal and stomach cancers were the most common cancers in Iran in 2016 and are predicted to remain the leading cancers nationally in 2025. The increasing trends in incidence of most common cancers in Iran reinforce the need for the tailored design and implementation of effective national cancer control programs across the country.

BACKGROUND Information regarding solid pseudopapillary neoplasm (SPN) of the pancreas is limited in Iran. We aimed to review the clinicocytopathological features and follow-up of patients with SPN of pancreas who were diagnosed in a single center in Iran. METHODS Seven patients with SPN of the pancreas were diagnosed during January 2010 to March 2015 at the Digestive Disease Research Institute of Tehran University of Medical Sciences. The patients were reviewed prospectively. RESULTS Six out of the 7 patients were female and the mean age of all the patients was 29.4 years ranging from 15 to 61 years. The most common clinical presentation was nonspecific abdominal pain (N=6). The tumors were located mostly in head and neck of the pancreas. SPN was diagnosed in all patients by fine needle aspiration through endosonography (EUS-FNA). All patients underwent surgery. Histological findings of surgical tissues were consistent with EUS-FNA. The postoperative follow-up period of about 14 months was uneventful. CONCLUSION SPN of the pancreas is a rare pancreatic tumor which affects primarily young women. EUS-guided FNA could play an important role in preoperative diagnosis of SPN of the pancreas.

Our results indicate that increased frequency of intake of bread, rice, and red meat (especially barbecued) and deep fried vegetables can aggregate PC risk, while increased frequency of fish consumption can protect against PC. However, more studies are still needed.
