Current research shows that each cancer has its own unique genetic properties and tumor-specific markers, and common features of many types of cancer [10] . In the face of the challenge of cancer precision medicine, an individual-centered multilevel human disease knowledge integration database must be established. Based on this, a “cancer knowledge network” that can be used to accurately classify diseases is formed, as shown in Figure 1. It is used to guide clinical practice evidence, provide knowledge of health and disease awareness, and is used in many ways for health care workers and patients [11] . With the rapid development of digital networks and science technology, individual self-care ability has gradually increased. People can use their own genetic files to understand that they may be sick and choose their own medical services [12] . Through data self-management and prevention, we have developed cancer precision medicine that can provide each individual with the best medical care [13] .

The primary task and important responsibility of nursing managers is not the manager but the development of nursing talent. In the current transformation of the precision medical model of cancer, nursing managers also need to change their management thinking and develop advanced practical nurses for cancer precision cancer nursing. Recent advances in tumor markers and biomedical technologies have begun to change the basic principles of cancer therapeutics and clinical trials. In order to design innovative adaptive tests, to develop accurate cancer treatment plans, and to provide appropriate, safe, and effective care, nursing staff are required to undergo standardized training, master relevant bio-marker knowledge, Malignant tumor-related molecular definitions and so on [14] . However genome testing also brings many ethical issues. Therefore, nurses need to understand the process of genome testing and the impact of the results and work collaboratively with the doctors [15] . In the process of clinical implementation of precise nursing, caregivers should maintain the right to be recruited and consent to participate in gene-spatial-related research, while also paying attention to the privacy of patients’ health information and their willingness to use their personal health information. We do our best to provide the optimal care and maximize the benefits for precise treatment of cancer patients.

At the same time, in the study of Adams L, a retrospective study was performed on histology types and staging of non-small cell lung cancer and metastatic melanoma [16] . The study found that increasing patients’ understanding of tumor genetics and molecular markers and expanding patients’ treatment programs can often improve their quality of life. Nursing personnel understand the role of genetics and molecular markers in the diagnosis and treatment process, will be able to better assess or anticipate patient needs and challenges, and provide precision medical-related nursing education and decision support [17] . We need to carry out advanced practice nurses’ practice, research, and education in genetics/genome to deepen advanced nursing practice research by identifying and implementing genome-based risk assessment, care, and management, and to contribute to the improvement of the genome health of all individuals and people [2] [18] .

Researchers such as Vorderstrasse A.A. suggest that changes in nursing education, clinical decision support, and health systems are necessary during the process of supporting and promoting precision medicine and providing patients with personalized assessments, nursing, and treatment [19] . However, nurses play a key role in providing cancer precision nursing. The implementation of precise nursing interventions by advanced practice nurses can help elderly cancer patients recover faster and improve their quality of life [20] [21] . Secondly, the clinical decision support system for advanced practice nurses in oncology is worth studying, and the opportunity to implement interventions from genome is worth exploring. Developing clinical decision support tools is a complex health information processing technology. The clinical decision support tools can translate and integrate genome information and patient information, providing advice and evidence for personalized care [22] . However, our country’s clinical decision support system can learn from the United States to establish a corresponding cancer knowledge network [23] .

In 2011, the TeleDiaFoS surveillance system developed by the Polish scholar Ladyzynski proved to be very beneficial for the conversion of diabetic ulcer wound area into basic parameters [24] . In the same year, the Vanderbilt-Ingram Cancer Center successfully developed the My Cancer Genome system, which aims to provide clinical decision support for oncology nurses [22] . This is the first personalized cancer decision support tool in the United States, with data from nursing, medical literature, and the Internet. Based on this, smart medical care has been developed by embedding a variety of sensors in medical devices and using information networks for mobile health-care services. It realizes the exchange and seamless connection of various medical data, and carries out real-time dynamic monitoring and continuous tracking management of clinical nursing and treatment measures to assist nurses in making precise nursing health decisions [25] .

The study points out that mastering the knowledge of systems biology improves the ability of nurses to implement evidence-based nursing practice and introduces patients and their families to new methods of diagnosis and treatment [27] [28] . Advanced practice nurses are an important part of the health-care system and they will be key implementer of cancer precise nursing [29] . Advanced practice nurses who have received professional training understand the process of collection, processing, analysis, and precise diagnosis and treatment of tumor-related specimens. They can inform patients about biological analysis risks and explain their prediction accuracy evaluation [30] .

Rapidly developing genetics and genome are changing all aspects of cancer nursing and practice [31] . Advanced practice nurses can spread the knowledge of genetic genome to cancer patients and their families, and guide them to advocate evidence-based genetic genome as a guideline for treatment to reduce the risk of cancer or improve the outcome of cancer symptom management [32] . The cognitive needs of patients for precision medicine have also become the theoretical basis for nurses to implement precision nursing measures for individuals.

Different tumor patients have different treatment responses to different chemotherapy drugs. The range of safety doses for anticoagulant drugs used in patients with thrombosis and toxic drugs used for patients with advanced cancer pain is too narrow. And many factors have caused precise doses to become a great challenge for clinical drug safety. The implementation of special management of medical and nursing integration for drug administration and genetic testing can help medical personnel and patients accurately manage the dosage and its side effects [12] .

Cancer not only seriously harms human health, but also brings great psychological pressure and mental stress to cancer patients. The tedious nursing work may lead nurses to focus on the physiological needs of cancer patients, such as analgesics and pain care treatment programs based on each patient’s genetic code and pain sensitivity [33] , while neglecting the patient’s psychological needs. Cancer precise nursing not only requires precise nursing for precise targeted therapies, but also requires precise nursing of cancer patient’s emotional and psychological. In the past, nurses usually used listening, documentary, and especially various types of scales to assess the patient’s physical state or mental state [34] . However, precision nursing is the analysis of the patient’s gene or gene spectrum, and accurate assessment of the patient’s physiological changes or mental state from the molecular biology level. Thus, appropriate patients can be given appropriate care at the right time and truly precision nursing, which can vary from person to person, from case to case, from treatment to treatment.

The principle of treatment for most cancer patients is based on surgical treatment, supplemented by chemotherapy and radiotherapy. Patients can resolve problems in a timely manner through the nurse’s precise nursing during the hospital, but most patients still have varying degrees of health problems or potential risks of complications after discharge. Because patients and their family members lack awareness of these symptoms, they often delay the best time for complications and other treatments [35] . So this requires nursing staff to extend precision care to the family. Research shows that continuing nursing may not improve the survival of gynecological poorly differentiated cancer patients [36] . However, focusing on patient needs and mental health, based on the patient’s gene or gene spectrum analysis, predicting problems, providing timely nursing interventions, providing precise nursing can avoid causing patients with insecurity and anxiety, and improving the relationship between nurses and patients [36] . In the process of continuous nursing, the nursing staff performs accurate phenotype or deep phenotype analysis of cancer patients, strengthens symptom management of patients, and implements precise nursing interventions so that the patient’s body is in the best state of recovery, which may improve the outcome of the prognosis.
