The Eurasian Colorectal Surgery Conference, traditionally known as the “Olympic Games” in the field of colorectal surgery, was held in Guangzhou the day before yesterday. Professor Wang Jianping, Vice President of Sun Yat-sen University and President of the Sixth Hospital of Sun Yat-sen University, said: With the gradual “aging” of Chinese society, simple and rapid screening for colorectal cancer should fall on community doctors, while the currently promoted anal preservation technology also has some abuses, many patients have saved their anus but lost their lives. The incidence of colorectal cancer in China is increasing at the rate of 3.9% per year “According to a survey conducted in 2005 on one-tenth of the country’s population, the incidence of new colorectal cancer patients is increasing at the rate of 3.9% per year, while the world average is only 2% growth rate.” Professor Wang Jianping told reporters. If China is already a large colorectal cancer country with a high incidence in absolute and relative terms, Guangzhou is one of the “leaders”. “Colorectal cancer is very high in Shanghai and Guangzhou. The figure for Shanghai in 2009 was 4.2 percent, and Guangzhou should be comparable.” Wang Jianping said. ”In fact, it is not the geographical location of Guangzhou that determines the incidence rate of colorectal cancer, which is also the third highest inside all malignant tumors in Guangdong Province. This type of cancer is characterized by high incidence in large coastal cities. The specific reasons we believe are closely related to genetic genes and the general social environment, as well as people’s increasingly westernized lifestyles.” Experts explain. In the past, the age of onset of colorectal cancer in China was generally early, and low-grade colon cancer was the most common. However, with the change of western diet structure and the intervention of colonoscopy, many polyps that have not yet become cancerous have been removed and treated, and now the average age and location of colorectal cancer is becoming more and more similar to that of developed western countries, that is, the phenomenon of “aging” is obvious, and the increase of colon cancer patients is greater than that of rectal cancer. Some foreign experts pointed out that in the field of colorectal cancer treatment, there is the phenomenon of abuse of new technology. In this regard, Prof. Wang Jianping believes that every new technology may have been overused in the process of popularization and application. However, he especially emphasized that the concept and technology of “anal preservation”, which is highly valued by colorectal cancer patients, should never be abused. Unfortunately, in many hospitals, there are cases of misuse of anal preservation in surgery and even in specialties. Due to the inappropriate grasp of doctors on whether anus preservation should be used or not, patients who should not be treated with anus preservation have incomplete surgery, recurrence of cancer, and even accelerated death. ”The popular treatment method of anus preservation was warmly sought after by patients as soon as it was introduced, because it can indeed maintain patients’ dignity and guarantee quality of life to a large extent. However, both doctors and patients should understand that the first priority after cancer is to preserve life, and the second priority is to preserve the anus. In other words, ‘cure first, function second’. This relationship should never put the cart before the horse.” Wang said there are strict indications for anal preservation, and patient conditions must meet a number of criteria. “In terms of age, it makes little sense to preserve anus in patients who are over 80 years old. In addition, the degree of cancer differentiation and the specific location are factors that must be weighed in adopting anus preservation surgery.” Shortage There are only 160-180 ostomates in China “Nowadays, colorectal cancer patients who have their anus removed will be fitted with a ‘stoma’ (artificial anus) after surgery, and many hospitals have ‘ostomate clubs’. Patients need to receive guidance from professional stoma makers in their daily operations to try their best to improve their quality of life.” Professor Wang admits that for such a large population, there are now only 160 to 180 professionally certified professional ostomates in China. ”The first ostomy school in China was established more than ten years ago in the former Zhongshan Medical University, and because the certificate was issued by the World Ostomy Association, the number of places was very limited and only 12 students were enrolled each year, and later an ostomy school was also established in Beijing. Despite this, the number of people who graduated with the certificate did not exceed 180, and this data should be very real and reliable.” Without the guidance of a professional ostomate, many foreign patients handle themselves well when they are in the hospital, but their situation takes a sharp turn for the worse when they return home, said Prof. Wang Jianping. “The local hospital medical staff will not teach him how to operate on a daily basis, so the patient has great difficulty in taking care of himself.” The lack of ostomates is one of the current challenges that needs to be addressed, he said. Prospects Rectal cancer screening should be the responsibility of community doctors “In the past, we always thought liver cancer and lung cancer were the most scary, but in fact, the incidence of stomach cancer and intestinal cancer together has now caught up with the first two.” China has gradually entered an “aging” society, which means that more people may be “involved in cancer” in their long old age. He admits that the ideal screening model and task of colorectal cancer screening should fall on community hospitals. “Changing stool habits and blood in the stool are signs of intestinal cancer, and a stool check can give a general idea of whether there is a lesion in the intestine. Also finger diagnosis technology can identify the vast majority of colorectal cancer patients, and if the hand can accurately feel a foreign body, it is nine times out of ten cancer.” He said community physicians should master quick and easy identification methods, such as seeing patients who are significantly thin and report sudden changes in stool habits, to screen for cancer by means of finger diagnosis, blood tests in stool and colonoscopy. ”From the perspective of health economics, colorectal cancer screening is the most ‘cost effective’.” Professor Wang Jianping told reporters that lung cancer, liver cancer and pancreatic cancer screening are not very meaningful. “Because the time from discovery to rapid growth of these tumors is very short, while colorectal cancer is a slow process, 70% is gradually developed from adenomas, the length of time is even between 8 to 15 years, if adenomas and polyps that are not yet cancerous are found early during this period, they can be completely cut off to prevent the disease from happening.” Experts recommend that people over 50 years old should include colonoscopy in their regular medical checkups; and those with a family history of such cancers, or a history of intestinal polyps, blood in the stool and abdominal pain, should report to a specialist regularly when they are less than 50 years old.
