Knowledge and attitude of women regarding breast cancer screening tests in Eastern Iran.

INTRODUCTION: According to recent statistics, there has been a rapid growth of breast cancer in developing countries. Thus, early detection is essential. This study is based on the perception of people in the Northeast of Iran regarding breast cancer screening. METHODS: In a cross-sectional study, 1469 women were selected randomly in the period from April to November 2016. The study population consisted of women or their companions referring to outpatient clinics or people in public urban areas who filled out a breast cancer screening questionnaire in an interview. RESULTS: The patients' age was in the range of 14 to 84 years (mean = 38.8). More than 84% of interviewees were not informed of breast cancer and screening tests. The main reasons mentioned by patients for their failure to do screening tests was 'absence of any symptom or problem' and 'they did not think it was necessary'.There was not a significant difference between income level, marital status and knowledge of people about breast cancer screening tests (P > 0.05). However, employment, education level and family history had a positive effect on people's awareness of breast cancer and its screening tests (P < 0.05). CONCLUSION: The lack of knowledge in people from low socio-economic classes was the main barrier to breast cancer screening. In this regard, organizing training programs by physicians and the media can help raise screening rates.

Demographic survey of four thousand patients with 10 common cancers in North Eastern Iran over the past three decades.

BACKGROUND: Cancer is a major cause of mortality in developing countries and correct and valid information about the epidemiology of this disease is the first step in the planning of health care in each region. The aim of this study was to determine the relative frequency, mean age and sex ratio of the most 10 common non-skin cancers in the world and Iran, among patients referred to an oncology clinic. MATERIALS AND METHODS: This descriptive study was conducted in Mashhad, north east of Iran. The data obtained from the records of patients referred to the private oncology center between the years of 1985-2012." According to the latest report of GLOBOCAN study commonest malignancies included were lung, breast, colorectal, prostate, stomach, liver, cervix, esophageal, bladder cancers and Non-Hodgkin lymphoma. RESULTS: A total of 4,606 cases were analyzed. The mean age was 55.5±13.8years (male: 59.5±13.9, female: 52.6±12.9). Overall, breast cancer (1,264 cases, relative frequency of 27.4%) was the most prevalent cancer; however the mean ages of diagnosis were not significantly different between 5-year time period divisions (p=0.290). The most common cancer in men was esophageal cancer (26.3%).The lowest mean age was related to women diagnosed with breast cancer (48.5±11.8) and men with non-Hodgkins lymphoma (48.4±17.8). There were statistically significant differences between the mean age of men and women with gastric (p=0.003) and esophageal cancers (p<0.001). Male to female sex ratios in our study for bladder, lung and stomach cancers were 6.57, 2.60 and 2.50 respectively. CONCLUSIONS: The results showed that breast cancer tends to be found in younger female patients and bladder cancer appears more often in men. Screening in target population in addition to early diagnosis may reduce death and disability.

Knowledge and perception toward colorectal cancer screening in east of Iran.

BACKGROUND: Colorectal Cancer (CRC) is the third most common cancer in Iran and its early detection is necessary. This study is based on perception of people in the east of Iran toward CRC screening. METHODS: In a cross-sectional study, 1060 randomly selected individuals who referred to Razavi Hospital of Mashhad, Iran, between September the 1(st), 2012 and February the 28(th), 2013 as patients or their visitors involved in an interview to fill a questionnaire on CRC screening. RESULTS: The participants' age ranged from 40 to 88 years (mean= 55). More than 90% had no knowledge of CRC and screening tests. The most cited reasons for not having screening tests were "did not have any problem" and "did not think it was needed". Although, older people had more knowledge of CRC (P= 0.033), there was no relationship between gender, health insurance status, family history of individuals and their knowledge about CRC (P> 0.050). Employment, education and higher income had positive effect on the perception of people toward CRC screening (P< 0.050). CONCLUSION: Lack of knowledge in people in lower socio-economical class with limited literacy is the most important barrier to CRC screening. As such, designing educational programs involving physicians and media is important to improve CRC screening rates.

Changes in daily activities of cancer patients after diagnosis: how do canadian and Iranian patients perceive the change?

BACKGROUND: Being diagnosed with cancer has major impacts on a patient's life. This study was conducted to explore how specific daily activities of patients change as a result of cancer diagnosis or its treatment and how these patients feel about such changes. METHODS: This was a cross-sectional descriptive study. Cancer patients referred to our clinics and by completing a questionnaire, they reported their daily activities and how they changed after diagnosis. A total of 201 patients in Canada and 167 patients in Iran completed the questionnaire. The research setting was the outpatient cancer clinics of the Jewish General Hospital in Montreal, Canada (February to April 2008) and Imam Reza Hospital and Ghaem Hospital in Mashhad, Iran (March to August 2008). RESULTS: More than 40 percent of the patients reported changes after the diagnosis in at least 8 out of 22 daily activities listed in the questionnaire. While a negative perception towards the changes was more common, some patients also perceived some changes as positive. More than half of the participants (56.9%) who were employed at the time of diagnosis experienced changes in the amount or type of their paid work after being diagnosed with cancer. CONCLUSION: The impact of a cancer diagnosis and treatment on a patient's daily activities is drastic. There is a need to provide support and interventions to help patients maintain daily activities they need and/or like. Further studies are needed to better understand the nature of such interventions.

Incidence of chemotherapy-induced amenorrhea after adjuvant chemotherapy with taxane and anthracyclines in young patients with breast cancer.

BACKGROUND: Chemotherapy-induced amenorrhea is one of long term side effects of adjuvant chemotherapy in patients with breast cancer which may interfere with their future reproductive function. Although amenorrhea is well recognized, the actual incidence following taxanes remains uncertain. METHODS: In a cross sectional study, we identified breast cancer patients aged 45 years or younger who were treated with adjuvant anthracycline and taxane-based regimens at three different oncology departments from 2001-2008. RESULTS: One hundred and nineteen patients met all eligibility criteria and consented to participate in a regular follow up program. The median age at diagnosis was 33.5 years (range, 25-41). Seventy (58%) patients developed amenorrhea for at least 12 months following completion of treatment, and regular menses were maintained in another 49 (42%) patients. No statistically significant association was found between age and development of amenorrhea, although those who experienced cessation of menses were older. CONCLUSION: Although taxane containing chemotherapy was associated with higher rate of amenorrhea compared to FAC, this was not statistically significant (P=0.11). Also, treatment with tamoxifen and Estrogen Receptor (ER) positive status was significantly correlated with chemotherapy induced amenorrhea.
