Incidence Rates and Time Trends of Skin Cancer in Golestan Province, Northeastern Iran, 2005-2018.

Background: Given the significant occurrence of skin cancer in the Middle East and the existing research gap concerning its incidence and trends, this research aimed to study the epidemiology and trend changes of skin cancer in the Golestan province, Northeastern Iran.

Methods: The Golestan Population-based Cancer Registry's (GPCR's) data bank was utilized to gather information on confirmed skin cancer cases in the province during 2005-2018. We used Poisson regression analysis for comparing incidence rates between groups.

Breast cancer incidence trends in Golestan, Iran: An age-period-cohort analysis by ethnic region, 2004-2018.

Background: We aimed to examine the effects of age, diagnosis year (calendar period) and birth year (cohort) on the incidence trends of breast cancer among Golestan women, Northeast Iran, 2004-2018.

Methods: Incidence data were obtained by residential status (urban/rural) and ethnic region (Turkmens/non-Turkmens). We calculated age-standardized incidence rates (ASRs) per 100,000 person-years.

Esophageal and gastric cancer incidence trends in Golestan, Iran: An age-period-cohort analysis 2004 to 2018.

Golestan province in the northeast of Iran is part of the Asian esophageal cancer belt and is known as a high-risk area for esophageal (EC) and gastric cancers (GC). Data on incident cases of EC and GC during 2004 to 2018 were obtained from the Golestan Population-based Cancer Registry (GPCR). The age-standardized incidence rates (ASRs) were calculated and presented per 100 000 person-years.

The Effect of Neoadjuvant vs Adjuvant Chemotherapy on Final Outcome of Patients with Triple Negative Breast Cancer.

Triple negative breast cancer (TNBC) accounts for about 10% to 20% of breast cancers, does not respond to endocrine treatment, and is more aggressive. Two chemotherapy methods suggested include neoadjuvant chemotherapy (NAC), performed before surgery, and adjuvant chemotherapy (AC), performed after surgery. In order to determine whether the choice of chemotherapy method has any impact on patients' outcome, the present study aimed to compare the overall survival (OS) and disease-free survival (DFS) of TNBC patients with a 10-year follow-up.

Population-based cancer survival in the Golestan province in the northeastern part of Iran 2007-2012.

Objective: We studied 5-year relative survival (RS) for 14 leading cancer sites in the population-based cancer registry (PBCR) of Golestan province in the northeastern part of Iran.

Methodology: We followed patients diagnosed in 2007-2012 through data linkage with different databases, including the national causes of death registry and vital statistics office. We also followed the remaining patients through active contact.

Mirizzi's syndrome in a cystic duct variation.

Mirizzi's syndrome is a rare complication of gallstone disease, that gallbladder lumen can lie alongside the common hepatic duct, resulting in inflammation and resultant bile duct stricture. Most cases are not identified preoperatively. Variations of the cystic duct and its point of union with the common hepatic duct are surgically important.
