Background: one of the most killing cancers globally and the fourth most relevant cancer, the pancreatic cancer has a great numbers of victims every tear, therefore, the goal of this study was to investigate the rate of incidence among residents of ilam in time span of 10 years, from 1385 till 1394.
Materials and Methods: this is a retrospective study during 1385 till 1394 in Ilam city. Our source of patients was the afflicted patients. The sample size and the statistical society of research were determined based on census. The research materials included of two types first included the demographic information of patients (age, gender, tumor type, level of education, residency, smoking and lipid profile) and the second part was some information about the pancreatic cancer (anatomical site, pathologic findings and lipid profile).using SPSS version 19, the data was analyzed.
Results: the statistical society included 25 individuals afflicted with pancreatic cancer in which the most prevalent age group was men older than 70 years (60 years) (31.3%). Furthermore, as time went on, the number of new cases increased.
Conclusion: the risk factors for occurring the cancer were the age group greater than 70 years, being male, lower educational situation, unemployment, living in an urban areas, smoking, hereditary, hyperlipidemia (LDL, TG, CHOL) and finding tumor in middle third of pancreatic (because of existing helicobacter pylori virus and impropriate diet). Being able to identify endangered people, one could begin treating patients and thereby, saving time, cost and increasing the rate of survivors.


Gastrointestinal cancers are one of the most common cancers in different societies, so that in the United States after prostate cancer, the digestive tract is the second most common non-dermal cancer. Cancer of the pancreas occurs when the cells inside the pancreas that are behind the stomach begin to replicate out of control and form a mass [1,2]. These cancer cells can attack other parts of the body. There are several types of pancreatic cancer, the most common type of pancreatic adenocarcinoma, which includes 85% of cases. These adenocarcinomas begin with the part of the pancreas responsible for making digestive enzymes [4,3]. Symptoms of this type of pancreatic cancer include yellowing of the skin, abdominal pain or back pain, weight loss without reason, fainting of the stool, dark urine and anorexia. Pancreatic cancer rarely occurs at the age of 40, and more than half of the pancreatic adenocarcinomas are over 70 years old [5,6]. Risk factors for pancreatic cancer include smoking, obesity, diabetes and specific genetic conditions [7]. The pathways for pancreatic cancer diagnosis are usually the combination of these techniques: computer tomography, blood tests, and tissue samples testing [8]. To prevent pancreatic cancer, maintaining healthy weight and limiting the consumption of red meat or processed meat is recommended [9]. The likelihood of getting cancer among smokers decreases in the event of quitting, and after 20 years, the likelihood of them becoming equal to the rest of the population [10]. Treatments for pancreatic cancer include radiotherapy, chemotherapy, palliative care, or a combination of these. Each of these methods is selected according to the clinical conditions of the patient [11]. Surgery is the only remedy that can cure the disease, but it may also be used to improve the quality of life without the possibility of treatment [12]. Management of pain and gastrointestinal medications are sometimes necessary. Also, palliative care is recommended for all cases of this disease, even for those caring for treatment [13].

In 2012, all types of pancreatic cancer were the seventh cause of cancer deaths, resulting in deaths worldwide of 330,000 in that year. In the United States, pancreatic cancer is the fourth cause of death from cancer [14]. This disease occurs more often in developed countries. The pancreatic adenocarcinoma typically has a very poor prognosis. In fact, after diagnosis, 25% of people survive a year, and 5% survive for 5 years. If cancer is detected early, the five-year survival rate will increase by about 20% [15]. The city of Ilam is geographically located in the western part of Iran, and the prevalence of pancreatic cancer is among the regions with a moderate prevalence. According to the necessity of research, the researchers decided that the epidemiological study of pancreatic cancer should be investigated as a 10-year retrospective study (1394 -1385) in Ilam province.

Materials and Methods

The present study is a retrospective study of the time interval of 1395-1384 in Ilam province. The list of patients who were in the province of Ilam with pancreatic cancer was selected. Sample size and statistical society were selected based on the census. The data were collected at the Cancer Registry in Ilam and reviewed by the patients who attended the Shahid Mostafa Khomeini Hospital in Ilam and some pathological laboratories diagnosed with pancreatic cancer. The researcher designed a checklist containing several sections, the first part containing demographic information of patients (age, gender, type of cancer, educational level, occupation, place of residence, smoking and family history), the second part includes information on esophageal cancer (location) Anatomical findings, pathological findings, and lipid profiles). The researcher collected and recorded their data and placed them in special formats and entered the SPSS-V 19 for analysis of the data. The results were analyzed using descriptive statistics (frequency, mean and standard deviation) and inferential statistics (K-SCORE and ONE WAY ANOVA). Values ​​less than 0.05 were considered as significant (P Value <0.05). At all stages of the study, the hallucinogenic principle was observed and no costs were borne by the patients. In all steps, the Helsinki rule was considered and there was no charge for patients.


The statistical society of the study, which consisted of 25 people with pancreatic cancer in Ilam province during the period of 1394-1385, was the most common age group of patients with pancreatic cancer who were more than 70 years old (60%) and men had a higher share than women (Tabl 1).

Table 1.Distribution of demographic data related to patients

In Fig 1 , the frequency of pancreatic cancer in the province of Ilam during the period of 10 years (1345-1394) is shown, with the increase in the year, the number of cases was also recorded, with the highest frequency of 1394 and the lowest frequency in 2006 is.

Figure 1. . The frequency of pancreatic cancer in the province of Ilam in the period of 10 years (1394-1385) shows that with increasing the number of registrations, the most frequent was 1394 and the lowest frequency is 1385

In Fig 2, the frequency of pancreatic cancer in cities is highest, with the highest frequency in the city of Ilam (18%) and the lowest Avon (8%).

Figure 2. . The prevalence of pancreatic cancer in terms of cities shows that the highest frequency is in the city of Ilam (18%) and the lowest Ayvan city (8%).

In Tabl 2, the mean lipid profile (Chol, HDL, LDL, and TG) in patients studied was given with details. The frequency of pancreatic cancer based on demographic variables showed that the most group of pancreatic cancer patients was more than 70 years old and was statistically significant (P value = 0.00) and with increasing age, the incidence of pancreatic cancer also increased Find out The incidence of cancer in men was higher than that of women, but it was not statistically significant (P value = 0.09). There was a significant correlation between the area of ​​residence and smoking and family history with the incidence of pancreatic cancer (P value = 0.04) and (P value = 0.03) and (P value = 0.02), so that among urban residents and individuals the smoker and family history of this infection were higher.

Nowadays, the pancreatic cancer is one of common cancer types globally which is also the sixth factor of cancer related deaths. Based on results from this study; the most general age group for having this type of cancer is people who are older than 70 years. The 41 to 50 was a lowest group in terms of incidence rate which results in the higher the age, the higher the chance of affliction. There are some similar studies both inside and outside of Iran deducting that aging may be a risk factor for pancreatic cancer because of poor diet and lacking of drinkable water [1,17]. Data explored from this study show that men are more in danger of getting sick which means gender is another risk factor, similar to previous analogous studies. So, based on what discussed above, men have more numbers of illness related to having full of stress careers, poor diet, more responsibilities in men and more works [4,7]. Education as another risk factor has its impact on incidence rate which people with diploma and with academic literacy had lower and higher rate of illness respectively. That shows that literacy may prevent people from getting sick or prevent to be exposed to risk factors which are similar to analogous studies [8,10]. Based on data in terms of job, unemployed people had a higher risk of getting cancer resulted from the stress of finding new job and their future led to over secretion of gastric acids and bad nutrition habits to appearance tumors in stomach [11,12]. One could conclude that having job is important factor. Data from occupancy situation imply that living in cities because of poor dietary regimen, more stress and harmful jobs would lead to increase the rate on cancer [13,14]. It seems that dwelling area is an important factor which needs more investigation about. As data derived from smoking have shown the higher level of incidence rate, one could conclude that so much carcinogens existing in cigarettes have been responsible for this outcome [15,16]. People with previous occurrence in close members of their families are the susceptible group which had the most incidence rate, so, as other similar studies have proved this matter, history is another determining factor [17,18]. As the time went on, it seemed that the number of new cases grew 7 to 10 times in recent years which may be because of underestimating the illness and its risk factors by people. The results of other studies show that this trend has been increasing since last decade because the nutrition and diseases were prevalent which is in a good accompany with this study [1,19]. In terms of anatomical site, the middle third of pancreatic had 75 cases (50%), the last third had 45 cases (30%) and the first third had 30 (20%) individuals which means as the rate of tumors in middle third, related to living HPV in this region of pancreatic, is increasing every day, the other two sites undergo declination. These results are similar to previous studies done in this area [1]. The level of blood lipids was more than normal limitation, 2 or 3 times in some patients, which implies on the effect of these lipids on appearance of pancreatic cancer. Some researchers believe that poor nutrition habits are in charge of enhancing tumor bearing patients [20].

In Conclusion, There are retrospective studies to find out the risk factors for the presence of the disease. In this study, several effective risk factors that caused pancreatic cancer in the province of Ilam during the 10-year period (1394-1385) were found. It can be mentioned from 70 years of age, male gender, low awareness (low education), lack of job (unemployment), urbanization, smoking, inheritance (familial history), high blood lipids (LDL, TG, CHOL) as our investigated risk factors.

Study restrictions

Retrospective studies have several limitations that can be pointed out: all specimens were people who had been referred to the hospital and were diagnosed, but the number of pancreatic cancer cases may be much higher than those that may have led to hospitals. They may have had another illness and have not been diagnosed at all, the other one that has been restricted from research has not been enough to provide patients and some patients with specialized equipment, which has led to procedures that were carried out in Patients did not find enough information and entered this information.


Because the risk factors of the disease are detected and detected, screening can be done to identify unknown cases, and many of these patients are diagnosed at the stage of the onset of the disease, and initially and secondary to prevention, and the duration of treatment and diagnosis is also shorter and less costly. As well as an increase in the survival rate of the patients, as well as an effective factor in the incidence of heredity cancer, relatives and family members can also be investigated and prevented, as well as educating patients about Taking proper food and identifying with the risk factors of the disease and two One of these factors is recommended.

Clinical application

If people at risk for pancreatic cancer can be identified, they can start treatment and save time and money, as well as increase the survival rate of the affected people and take an important step in reducing mortality in cancer patients.
