Pancreatic cancer early diagnosis method and system based on multi-modal fusion

Abstract

The invention discloses a pancreatic cancer early diagnosis method based on multi-modal fusion, which is characterized by comprising the following steps: step 1, preprocessing blood test data and image data of a patient to obtain blood test data features and image features; 2, fusing the image features and the corresponding blood test data features, and training a classification model by taking a bimodal fusion result as a data set to obtain a multi-modal pancreatic cancer early diagnosis model; 3, according to the blood test and image results of the patient, the multi-mode pancreatic cancer early diagnosis model is adopted for diagnosis work. The diagnosis method can be used for early diagnosis of pancreatic cancer high-risk groups, the accuracy rate of an early diagnosis model reaches 82.21%, the early pancreatic cancer diagnosis accuracy rate is greatly improved, early diagnosis and early treatment of pancreatic cancer patients are achieved, and the survival rate is increased. The invention further discloses a pancreatic cancer early diagnosis system based on multi-modal fusion. The pancreatic cancer early diagnosis system comprises a preprocessing part and a diagnosis part.

Description

technical field [0001] The present invention relates to the field of computer vision and the field of medicine, in particular to a method and system for early diagnosis of pancreatic cancer based on multimodal fusion. Background technique [0002] Pancreatic cancer is one of the most malignant and lethal tumors among solid tumors, and is known as the "king of cancers". The latest statistics from the National Cancer Center of China also confirm that pancreatic cancer ranks eighth in male malignant tumor incidence in Chinese cities and sixth in malignant tumor death rates in large cities (Beijing and Shanghai). The five-year survival rate for pancreatic cancer is only 6%. In 2018, there were nearly 450,000 new cases of pancreatic cancer worldwide, and more than 430,000 deaths. It is estimated that by 2030, pancreatic cancer will become the second leading cause of cancer death worldwide. Its high mortality rate is attributed to the lack of obvious early symptoms, lack of effe...

AI Technical Summary

Problems solved by technology

Its high mortality rate is attributed to the indistinct early symptoms, the lack of effective diagnostic methods, and the rapid progression of the disease, etc.

Although researchers have made a lot of efforts to improve the prognosis of pancreatic cancer patients in recent years, such as studying the mechanism of pancreatic cancer development and exploring various early diagnoses, the high mortality rate has not been significantly improved
