Pathologists have long been referred to as “doctor′sdoctor” in foreign hospitals. This is partly because pathologists generally do not deal with patients directly, but mainly work with clinicians. On the other hand, it further emphasizes the close integration of clinical and pathology. The integration of clinical and pathology is not only manifested in mutual cooperation in diagnosis, but also in joint participation in treatment. For example, in terms of understanding of tumors, since all tumors are classified and named by pathologists and the final diagnosis is made by pathologists, it is said that pathologists have the most profound understanding of each case. The biological behaviors of different pathological types of tumors, that is, the degree of benignity and malignancy as well as the ability to infiltrate and metastasize, are different; the same type of tumor can show different biological behaviors in different patients, and these factors are very important to correctly judge the patient’s prognosis and choose the appropriate treatment plan. Nowadays, targeted therapy for tumors is very popular and these drugs are very expensive. The correct targeted therapy depends on accurate pathological diagnosis by pathologists and accurate testing of relevant indicators, such as HER-2 test criteria positive for breast cancer to be treated with Herceptin and CD20 criteria positive for B-cell lymphoma to be treated with Merova. Therefore, the active participation of pathologists is very much needed to truly individualize the treatment of patients. Furthermore, many diseases diagnosed by pathologists may be unfamiliar to clinicians and have not been encountered in the past, or even cannot be found in books. Then it is more important to further discuss with the pathologist together to jointly develop the next examination methods and treatment plans for the patient. Such clinical pathology seminars are very common in foreign hospitals, but we are relatively lacking in China.
