With the progress of medical technology and the popularization of advanced medical equipment, most tumor patients can get clear diagnosis and corresponding treatment in primary hospitals. However, what cannot be ignored is that patients treated in primary hospitals have relatively low long-term survival rates, more postoperative complications and not significantly less medical costs. The main factor is that the patients admitted to the primary hospitals are not selective and often are the source of patients eliminated from large hospitals, mostly with advanced tumors, advanced age or with more underlying diseases. In addition to the above factors, some primary care doctors have misconceptions about tumor, retain traditional concepts, and the development of new technologies and therapies is interfered by subjective or objective factors. 1. The concept of surgery only. We know that the treatment of tumor is a multidisciplinary joint and systemic treatment process, which requires time and space to complete. Neoadjuvant chemotherapy has been widely accepted by oncologists and patients, and radiotherapy and chemotherapy before surgical resection of tumor has a great influence on the long-term survival of tumor patients. Most primary care physicians only focus on surgical treatment and neglect radiotherapy and chemotherapy. They are even more resistant to neoadjuvant chemotherapy, which delays the disease, prolongs the effective treatment time and caters to the patients’ fear of survival with tumor. Even adjuvant radiotherapy and chemotherapy are not done after surgery, and everything is done for the tumor. 2. The concept of lymph node removal is not accurate enough. In the process of tumor resection, lymph node clearance plays a decisive role in the postoperative long-term survival, which is of great significance to most tumor patients. The standardized lymph node clearance helps to stage the tumor and guide the postoperative treatment. Some primary care physicians do not know enough about lymph node dissection for tumor resection, and do not dissect or do not standardize lymph node dissection during surgery. In addition, some doctors from higher level hospitals go to primary hospitals to do surgery, because of many concerns, they also do not clear or do not standardize lymph node clearance, and only pursue recent efficacy, which misleads primary doctors even more. In this way, there is neither the basis of lymph node metastasis nor the habit of looking for lymph nodes within the specimen. The postoperative staging of tumor is very blind and cannot guide the development of postoperative treatment plan, which sometimes delays the later treatment. 3. There is a lack of post-operative evaluation, health education, life guidance and long-term follow-up of tumor. Every aspect of tumor treatment is very important and sometimes the details determine success or failure. Doctors can make prospective assessment of late survival status through intraoperative condition, tumor morphology, pathological staging, lymph node metastasis and systemic condition to make high quality survival. Good health education and proper life guidance can avoid many postoperative complications. Long-term follow-up of tumor patients can keep track of their survival, improve evidence-based medicine, and guide their recovery and treatment.
