This prospective cohort study is designed to explore the role of environmental, clinical, and genetic risk factors in the progression and prognosis of primary liver cancer (PLC). We will recruit 5000 patients with newly diagnosed, previously untreated PLC. The eligible patients will be asked to complete a baseline survey at the time of initial admission and be followed up every 3 to 6 months after discharge.
Primary liver cancer (PLC) is highly malignant and is particularly prevalent in China. Multiple factors are involved in the development and progression of PLC. Several large-scale, prospective cohort studies have been established to identify environmental and genetic risk factors for the development of PLC in the general population. However, few cohort studies have focused on determining risk factors beyond clinical prognostic factors for the progression of PLC in patients with PLC. Therefore, we will conduct a prospective cohort study to examine the role of environmental, clinical, and genetic risk factors in the progression and prognosis of PLC. We plan to recruit 5000 patients with newly diagnosed, previously untreated PLC. A baseline survey will be conducted at the time of initial admission, with follow-up at 3 and 6 months after discharge for all patients and thereafter every 3 months for patients treated with interventional therapy and every 6 months for patients receiving surgery and other therapies. We will collect information on patients' demographics characteristics, clinical diagnosis and treatment, lifestyle, nutritional status, psychological and mental status, quality of life, anthropometric data, body composition, routine laboratory tests and examinations, and disease progression through structured questionnaires, physical examinations, and medical record reviews. Deaths will be ascertained through medical records, death certificates, and next-of-kin. Additionally, we will collect blood, urine, stool, and liver tissue samples.

| Death | The primary endpoint of this study is all-cause mortality and liver caner-specific mortality. The exact death time and the cause of death of each participant will be checked in the government medical records system. | Up to 20 years |
| Measure | Description | Time Frame |
|---|---|---|
| Recurrence (intrahepatic and extrahepatic) | Time of recurrence will be obtained by telephone interview or medical treatment records | From date of diagnosis until the date of cancer recurrence or date of death from any cause, whichever came first, assessed up to 20 years |

Time of newly emerging diseases will be obtained by telephone interview or medical treatment records |
| From date of diagnosis until the date of newly emerging diseases or date of death from any cause, whichever came first, assessed up to 20 years |
| Response Evaluation | For patients undergoing surgical treatment, assess whether there is recurrence. For patients receiving ablation therapy, evaluate whether the tumor is completely ablated. For patients undergoing interventional therapy and radiotherapy, use the modified Response Evaluation Criteria in Solid Tumors (mRECIST) for hepatocellular carcinoma to evaluate efficacy. Use the RECIST 1.1 criteria for efficacy evaluation for patients undergoing systemic anticancer treatment. For patients receiving anti-angiogenic molecular targeted therapy, use the mRECIST criteria in combination. For patients receiving immuno-checkpoint inhibitor therapy, use the iRECIST criteria. Short-term efficacy evaluation indicators include the objective response rate (ORR), progression-free survival (PFS), disease-free survival (DFS), etc. | through study period, every 3-6 months |
| Nutritional status | To assess the nutritional risk, the patient will be screened by Nutrition Risk Screening 2002 (NRS-2002), patient-generated subjective global assessment (PG-SGA), the global leadership initiative on malnutrition (GLIM). | through study period, every 3-6 months |
| Quality of life | The assessment is based on the European Organization for Research and Treatment of Cancer (EORTC) quality of life core questionnaire QLQ-C30 for all cancer patients, the specific quality of life subscale QLQ-HCC18 for patients with liver cancer or QLQ-BIL21 for patients with intrahepatic cholangiocarcinoma. | through study period, every 3-6 months |
| Psychological and mental status | Anxiety and depression are evaluated using the Generalized Anxiety Disorder 7-item scale (GAD-7) and Patient Health Questionnaire 9-item Depression Scale (PHQ-9), recommended by the American Society of Clinical Oncology (ASCO) Adult Cancer Survivor Anxiety and Depression Management Guidelines. | through study period, every 3-6 months |
| Cachexia assessment | Use the Anorexia Cachexia Subscale-12 (A/CS-12) to assess anorexia, and utilize the CASC-IN tool to evaluate whether the patient has cachexia. If cachexia is present, the cachexia scoring system (CASCO) should be used for further assessment of the cachexia stage. | through study period, every 3-6 months |
| Sarcopenia | Utilize the Simple Five-Item Scale (SARC-F) questionnaire to screen if the study subjects have sarcopenia. | through study period, every 3-6 months |
| Frailty | Assess frailty using the Liver Frailty Index (LFI). This index considers the following assessment items: (1) Dominant hand grip strength; (2) Time to do 5 chair stands; and (3) Seconds holding 3 position balance. | through study period, every 3-6 months |
