Core Insights - The Chinese Academy of Medical Sciences Cancer Hospital has established the first large-scale pan-cancer real-world genomic database in China, revealing differences in genetic variation characteristics between Chinese and Western cancer patients, which is crucial for precision cancer treatment and clinical trial design [1][2] Group 1: Database Establishment - The research team, led by Professors Li Wenbin and Ying Jianming, collected samples from nearly 7,000 patients who underwent genetic sequencing, covering 54 common types of tumors [1] - The database addresses the long-standing lack of genomic data for Asian populations, particularly in China, which has hindered the applicability of existing international treatment standards for Chinese patients [1] Group 2: Research Findings - The study found that four types of gene mutations have the highest frequency among Chinese patients, with one gene inactivation mutation occurring in over 80% of cases in esophageal squamous cell carcinoma, small cell lung cancer, and lung squamous cell carcinoma [2] - Specific gene mutation rates in Chinese lung adenocarcinoma patients were significantly higher than those in Western populations, filling a critical gap in the understanding of pan-cancer genomic characteristics in China [2] Group 3: Future Implications - As clinical follow-up data continues to improve, the database is expected to provide deeper insights into the relationship between tumor molecular characteristics, treatment efficacy, and patient prognosis, supporting precision prevention, diagnosis, and treatment of cancer [2]

Group 1: Personal Journey and Motivation - Wang Hongyang's return to China was motivated by a desire to contribute to the development of liver cancer research, inspired by her mentor Wu Mengchao's vision for a research-oriented hospital [2]. - Her experiences studying in Germany highlighted the disparities in medical research and practice, which fueled her commitment to elevate China's standing in the field [1][2]. Group 2: Research Contributions and Innovations - Under Wang's leadership, the laboratory evolved into the National Liver Cancer Science Center, focusing on the integration of basic research and clinical applications [3]. - Key achievements include the discovery of new therapeutic targets for liver cancer, the development of China's first fully proprietary liver cancer diagnostic kit, and advancements in early diagnosis and intervention strategies [3][4]. - The establishment of a diverse biobank for liver cancer research has positioned China as a leader in this area, facilitating significant breakthroughs in treatment and diagnosis [2][3]. Group 3: International Collaboration and Recognition - Wang has played a pivotal role in fostering international cooperation, notably by facilitating the American Association for Cancer Research (AACR) conference in Shanghai, enhancing China's global influence in cancer research [4]. - Her recognition as a "Outstanding Figure in the Overseas Chinese Community" reflects her contributions to international collaboration and the promotion of scientific exchange [5]. Group 4: Future Goals and Aspirations - Wang's team aims to align with national strategic needs to reduce liver disease incidence and mortality, focusing on early diagnosis and effective treatment of liver cancer [5]. - She expresses hope for the younger generation of overseas Chinese to contribute significantly to Shanghai's development as a modern international metropolis [5].

Core Viewpoint - The article argues for a paradigm shift in cancer research, moving away from the dominant "somatic mutation" theory, which has not led to effective cancer cures, towards a more holistic understanding of tumors as complex systems influenced by ecological and evolutionary factors [2][3][21]. Cancer Research Paradigm - The "somatic mutation" theory has been the mainstream paradigm in cancer research, suggesting that specific gene mutations are the primary drivers of malignancy [4]. - Historical milestones in cancer research have established a strong focus on genetic and molecular studies, leading to the entrenched belief that "without genes, there is no mechanism" [4][5]. - Despite advancements in sequencing technologies and the emergence of hundreds of new cancer drugs, many cancer types still struggle to achieve long-term disease-free survival [3][5]. Tumor Ecology - Tumor ecology emphasizes the interactions between cancer cells and their microenvironment, highlighting the importance of ecological dynamics in understanding tumor behavior and treatment resistance [10][11]. - Cancer cells adapt to harsh environments through processes like epithelial-mesenchymal transition, which allows them to survive and proliferate under treatment stress [10]. - The article suggests that tumor characteristics such as angiogenesis, immune evasion, and inflammatory responses can be viewed as ecological factors influencing tumor adaptation and survival [11]. Evolutionary Perspectives - The concept of tumors as systemic diseases is supported by various studies that highlight the role of developmental constraints and the influence of the immune system on tumor progression [8][9]. - The article discusses the need to consider evolutionary dynamics in cancer treatment, proposing strategies that focus on controlling selection pressures rather than completely eradicating tumors [19]. Ecological Pathology - The emerging field of ecological pathology integrates ecological and evolutionary principles to study the causes and mechanisms of diseases, including cancer [15][16]. - Cancer cells interact with their microenvironment and other cell types, leading to complex adaptive strategies that can influence tumor progression and treatment outcomes [16][18]. - The article advocates for incorporating ecological insights into current pathological diagnostics to better understand tumor behavior and treatment responses [20]. Future Directions - The article calls for a rethinking of cancer research frameworks, emphasizing the need for a systematic and ecological approach to understand and treat malignancies effectively [21]. - It highlights the potential of integrating ecological and evolutionary theories into cancer research to develop innovative treatment strategies that address the complexities of tumor biology [21].
