We do not know exactly why pancreatitis is a risk factor for pancreatic cancer. However, research does shown that there is an increased risk of developing pancreatic cancer if you have chronic pancreatitis. Therefore, it is something to be aware of. Pancreatitis is an inflammation swelling and soreness of the pancreas whereas pancreatic cancer is a tumour in the pancreas.
There are two main types of pancreatitis: acute short term and chronic long term. Chronic pancreatitis is long-term inflammation of the pancreas which causes scarring of the pancreas.
Because the pancreas tissue that is necessary for digesting food is gradually destroyed by this condition, and replaced by scar tissue, people with chronic pancreatitis can develop malabsorption. Malabsorption is a condition in which there is a difficulty digesting or absorbing nutrients from food.
The insulin-producing cells are embedded in the pancreas and, if the scarring is extensive, pancreatic function is impaired and diabetes can also occur. Some long-term medicines are thought to be associated with chronic pancreatitis, for example certain epilepsy medicines. Chronic pancreatitis is a risk factor for pancreatic cancer, increasing the risk of pancreatic cancer by 2 to 3 times that of the general population.
However, smoking is a risk factor for both pancreatic cancer and chronic pancreatitis, so the relationship between the two is not completely clear.
Diabetes which has developed recently and not linked to weight gain can also be a warning sign of pancreatic cancer. Pancreatic cancer should therefore be excluded by a CT scan in people with new signs of chronic pancreatitis and especially with new signs of diabetes. Because of the similarities between the symptoms of chronic pancreatitis and pancreatic cancer, it can be difficult to make the distinction without specialist input, a CT scan which often needs repeated at an interval of several months and occasionally an endoscopic ultrasound test, which can involve a biopsy.
Please see the NHS website for more about symptoms of chronic pancreatitis. The involvement of a dietician or dietary advice is very helpful: because fat is not absorbed well in chronic pancreatitis, low fat diets can lessen symptoms of malabsorption. Vitamin supplements are often advisable. Chronic pancreatitis can be painful, so people may need to take medication to manage the pain. Occasionally, pain relief needs to be quite strong.
Surgery for pancreatitis is not done very often and is becoming even less common. Surgery for chronic pancreatitis can help but should only ever be considered after a prolonged period of discussion with specialist pancreas surgeons. Find out more about pancreatitis here.

Symptoms of chronic pancreatitis How is it treated? Symptoms of chronic pancreatitis Chronic pancreatitis presents many symptoms similar to pancreatic cancer, including: Severe tummy pain or digestion problems. These are progressive episodes that happen frequently and are quite severe.
Mild pain between the episodes can also be experienced, particularly in people that continue to drink alcohol. Operative procedures, tumor histology, and postoperative results of the 39 patients who received surgery. The time of surgery was calculated from the date of the first attack of AP if pancreatitis was recurrent, then the time of surgery began with the latest attack.
ROC was used to analyze the best time cutoff from the first attack of AP to surgery according to early postoperative complications Fig. The best cutoff point of surgery was Twenty-five Interestingly, early postoperative complications occurred in 12 patients. Compaction outcomes of selected patients who underwent surgery at The median follow-up for patients was 24 months range 4—54 months.
The survival rate of patients with PC presenting initially with AP was During postoperative therapy, 5 Kaplan—Meier survival curves in patients with pancreatic cancer who present with acute pancreatitis. This retrospective study supports the assumption that AP is the early presenting clinical symptom of PC. The rate of AP in PC patients varies widely and has been reported to range from 6.
To our surprise, The underlying mechanisms and the nature course of this disease are unclear. Recently, one possible explanation was obstruction of pancreatic ducts, [ 3 , 8 ] which resulted in the dilatation of main pancreatic duct and activated pancreatic enzymes. A similar observation was also made by other studies [ 9 , 10 ] in patients with intraductal papillary mucinous neoplasms IPMNs presenting with AP.
They believed that AP recurring after IPMN resection was the result of sudden obstruction of the main duct by abundant mucus secretion. Moreover, Kimura et al [ 6 ] reported that PC may produce some chemical mediators, which may be responsible for AP. However, in our study, not all the cases present with dilatation of main pancreatic duct 6 patients.
Why did AP happen in the absence of main pancreatic duct obstruction? Pelletier et al [ 11 ] reported that the slow growth of PC may not narrow the main pancreatic duct; thus, AP did not occur frequently. Although the link between a history of AP and pancreatic tumors was uncertain in human body, animal studies have identified that AP could markedly accelerate PC development. All mouse subjected to two brief episodes of AP. They concluded that acute inflammation of the pancreas dramatically enhanced the risk for pancreatic malignant transformation.
Up to now, there is no guideline concerning the timing of surgical intervention in patients with PC pre-existing AP. AP is still a challenging disease with a high rate of morbidity and mortality. The first phase is systemic inflammatory response syndrome SIRS , which occurs 1 to 2 weeks after onset of the disease. The second phase occurs after 2 weeks, which is called counteractive anti-inflammatory response syndrome CARS.
Patients with signs of mild AP were successfully treated by a conservative approach. Only 4. Although patients with severe AP were admitted to an intensive care unit, no mortality happened.
Infected necrosis was found in 2 patients and required necrosectomy at the same of distal pancreatectomy. Although previous studies concerning optimal treatment strategy of patients with PC pre-existing AP have yet to be defined, our study suggested that Over half of the patients They believed that the severity of the AP was mainly determined by the type of acinar cell death apoptosis or necrosis as well as by the systemic inflammatory response mediated.
Patients might die from severe attack after surviving in the initial phase. Regardless of the fact that some of these complications were not life-threatening events, the course of enhanced recovery after surgery ERAS was greatly influenced. All in all, early surgery may be not helpful to the recovery of patients. With respect to the effect of surgery on survival in the patients with AP secondary to PC, 1-year survival rate was However, operation pattern, tumor stage, and vascular resection with reconstruction were found to be associated with overall survival.
It was widely accepted that radical surgery was the only curative treatment option for PC. The median survival rates of patients who underwent resection was 20 to 24 months, compared with 3 to 6months in unresectable patients.
And the median survival in resection patients was 18 months. Our conclusions could be explained as the follow reasons. Intraoperative radiation therapy and postoperative therapy including chemotherapy or chemoradiotherapy were available for patients with long-term survival. So, it may be not surprising that the median survival was a litter longer than others. In addition, in our study, the aim concerning vascular resection and reconstruction was mainly to require R0 resection in 14 patients. The fact that these patients with radical resection had received tumor-free resection margins, in some extent, suggests that patients having an earlier stage of cancer and AP might be the first clinical symptom.
As AP is a rare manifestation of PC, these groups of patients are usually misdiagnosed. In the present study, the causes of misdiagnosis are unclear. Generally, patients with PC was diagnosed in the first year after AP.
Minato et al [ 31 ] suspected that diffuse pancreatic inflammation might have masked the presence of an underlying lesion in the pancreas or a small-sized tumor may preclude an early diagnosis of cancer.
Another cause might be that a pancreatic mass was difficult to found on the images in the early stage of cancer. The 6 patients had no tumor on images. Of the 6 patients, Tix was identified in 3 patients, the survival of whom were 5, 28, and 50 months, respectively. And, 2 of them were still alive at the follow-up period. Our study has several limitations. First, the correlation between the topography of PC and the occurrence of AP is not clearly interpreted because of the retrospective nature of the study.
Due to missing data on some important variables, patients diagnosed as AP in other medical center were excluded from the study. Furthermore, the sample size was small, and the time of our follow-up period was short.
Hence, further studies are urgently needed. In conclusion, AP could reveal PC at an earlier stage. Surgery after However, the time of surgery is mainly determined by the clinical condition of the patient.
Patients with vascular resection and reconstruction had a long-time survival. The authors have no funding and conflicts of interest to disclose. National Center for Biotechnology Information , U.

People diagnosed with chronic pancreatitis have an increased risk of developing pancreatic cancer. Chronic pancreatitis is a condition that can strike people of any age. It is typically diagnosed in people who are years old.
It can be due to a number of factors including hereditary genetic pancreatitis, malformation of pancreas ducts, trauma to pancreas, or excessive alcohol abuse for many years. Click here for more information on pancreatitis.
Diabetes : Pancreatic cancer is two times more likely to occur in people who have diabetes than in people who do not have diabetes. However, the relationship between diabetes and pancreatic cancer is still not completely understood. It is not uncommon for individuals to develop diabetes before pancreatic cancer is detected and it may be that this glucose intolerance is actually caused by changes in the pancreas resulting from the cancer.
