Age pattern of the occurrence of breast cancer in the northwest of Iran.

Breast cancer represents 27% of the cancers and 19% of the cancer deaths in female population. The aim of this study was to document the age pattern of the incidence of breast cancer in Iranian female population in the northwest region of the country. The study subjects were 1764 patients with breast cancer diagnosed/registered in the six university clinics between 1988 and 2008 in the northwest of Iran. The highest occurrence rates were observed for the birth year cohorts 1940-1949 (for 59-69 years old), 1950-1959 (for 49-58 years old), and 1960-1969 (for 39-48 years old). Among these three cohorts, the highest rate was observed in 1950-1959 birth year cohort (284.38 per 100,000 female populations, 95% CI: 260-310). This rate was significantly higher compared with the similar rates of other birth cohorts. There was no statistically significant difference between various years in terms of the average age at the diagnosis of breast cancer in our study setting. Despite the previous research reports, we found no significant difference between the mean ages at diagnosis of breast cancer from 1988 to 2008 in Iranian female population.

Usefulness of red blood cell flags in diagnosing and differentiating thalassemia trait from iron-deficiency anemia.

BACKGROUND: Thalassemia trait (THA) is an important differential diagnosis of iron deficiency anemia (IDA). The red cell distribution width (RDW) is usually elevated in IDA, but often is normal in THA. OBJECTIVE: This study was conducted to determine the usefulness of red cell flags in differentiating iron deficiency anemia and thalassemia trait. METHODS: Peripheral blood samples from 50 patients suffering iron deficiency anemia and 64 patients suffering thalassemia trait were used to determine red cell flags (RCF) along with complete blood count, red cell distribution width, serum iron and total iron binding capacity, ferritin and hemoglobin electrophoresis. According to the data collected in this study, the first digit of red cell flags (RCF1)=0 was almost three times higher in thalassemic patients compared to those of iron deficiency anemia. Another reverse significant difference was observed in RCF1=2 (6.3% versus 42% for thalassemia and iron deficiency anemia respectively). CONCLUSION: We conclude that RCF findings are sensitive and specific enough to be used as an approach in differentiating iron deficiency anemia from beta-thalassemia trait.

Human leukocyte antigen and esophageal cancer in the northwestern region of Iran.

Esophageal squamous cell carcinoma is the 6th most commonly occurring cancer worldwide. A relationship between HLA A1 and B40 and esophageal cancer was described in patients examined in China. The aim of this study was to investigate the relation of HLA class 1 and esophageal carcinoma in the northwestern region of Iran. Using specific monoclonal antibodies, different human leukocyte antigens (HLA) were quantified in 100 patients suffering esophageal carcinoma in Tabriz, a major city located in the Northwestern region of Iran. These data were compared to those of 100 healthy matched individuals as a control group from the same region. HLA B14 and A24 were increased and showed statistically significant correlation in squamous cell carcinoma. These findings may also indicate the association between genetic factors and esophageal carcinoma. Further studies are suggested for detecting correlation of HLA and esophageal carcinoma in other regions.
