Perioperative Risk of Immunotherapy Based Neoadjuvant and Conversion Therapy for Hepatocellular Carcinoma

Summary

This study aims to retrospectively collect a cohort of participants with hepatocellular carcinoma who received immunotherapy-based neoadjuvant/translational treatment. A multi-dimensional and multi-method analysis plan will be adopted. The goal is to provide solutions for better application of neoadjuvant immunotherapy and to offer better evidence for conducting prospective clinical research on hepatocellular carcinoma.

Inclusion Criteria:

Participants must meet all of the following conditions in order to be enrolled in this study:

1. Voluntarily participate in this study and sign an informed consent form.

3. Received immunotherapy based neoadjuvant or conversion therapy.
4. Complete recovery from surgical resection within 4 weeks prior to enrollment.
5. Child Pugh liver function rating A or B (≤ 7 points).
6. ECOG PS score was 0-1 points.
7. Expected survival time ≥ 12 weeks.
8. If suffering from hepatitis B virus (HBV) infection, it is necessary to be willing to receive antiviral treatment throughout the study period (according to the diagnostic and treatment guidelines, such as entecavir) and regularly monitor it; Hepatitis C virus (HCV) ribonucleic acid (RNA) positive subjects must receive antiviral treatment according to the diagnosis and treatment guidelines, and their liver function must be within CTCAE1 level elevation.

Exclusion Criteria:

If a subject meets any of the following conditions, they will not be allowed to enter this study:

1. Known hepatobiliary carcinoma, sarcoma like hepatocellular carcinoma, combined hepatocellular-cholangiocarcinoma and fibrous layer cell carcinoma; Within 5 years or simultaneously suffering from other active malignant tumors other than hepatocellular carcinoma (excluding cured skin basal cell carcinoma and cervical carcinoma in situ).
2. There are uncontrollable extrahepatic metastases, such as lung and brain metastases (EHS).
3. Participants who are preparing to undergo or have previously received organ or allogeneic bone marrow transplantation.
4. Participants who are currently accompanied by interstitial pneumonia or interstitial lung disease, or have a history of interstitial pneumonia or interstitial lung disease that requires hormone therapy in the past, other pulmonary fibrosis, organized pneumonia (such as bronchiolitis obliterans), pneumoconiosis, drug-related pneumonia, idiopathic pneumonia, or subjects with evidence of active pneumonia or severe lung function impairment seen on chest computed tomography (CT) images during screening, are allowed to have radiation induced pneumonia in the radiation field; Active tuberculosis
5. Currently, there is active autoimmune disease or a history of autoimmune disease that may recur (including but not limited to: autoimmune hepatitis, interstitial pneumonia, uveitis, enteritis, pituitary inflammation, vasculitis, nephritis, hyperthyroidism, hypothyroidism \[subjects that can be controlled only through hormone replacement therapy can be included\]); Subjects with skin diseases that do not need systematic treatment, such as vitiligo, psoriasis, alopecia, controlled type I diabetes that receive insulin treatment, or childhood asthma that has completely alleviated without any intervention after adulthood can be included; Asthma subjects who require medical intervention with bronchodilators cannot be included.
6. Suffering from hypertension and unable to achieve good control through antihypertensive drug treatment (systolic ≥ 140 mmHg or diastolic ≥ 90 mmHg) (based on the average BP reading obtained from ≥ 2 measurements), it is allowed to achieve the above parameters through the use of antihypertensive therapy; Previously experienced hypertensive crisis or hypertensive encephalopathy.
7. Participants with moderate to severe ascites with clinical symptoms who require therapeutic puncture or drainage, or whose Child Pugh score is greater than 7 (excluding those who only show a small amount of ascites on imaging but do not have clinical symptoms); Uncontrolled or moderate to equal amounts of pleural effusion and pericardial effusion.
8. There are clinical symptoms or diseases of the heart that cannot be well controlled, such as: (1) According to the standards of the New York Heart Association (NYHA), level II or above cardiac insufficiency or cardiac ultrasound examination: LVEF (left ventricular ejection fraction)\<50%; (2) Unstable angina pectoris; (3) Have experienced myocardial infarction within one year prior to the start of the research treatment; (4) Clinically significant supraventricular or ventricular arrhythmias require treatment or intervention; (5) QTc\>480ms (QTc interval is calculated using the Fridericia formula; if QTc is abnormal, it can be detected continuously three times every 2 minutes, and the average value is taken).
9. History of spontaneous rupture of liver tumors.
10. Individuals with a history of hepatic encephalopathy.
11. Congenital or acquired immune dysfunction in subjects (such as HIV infected individuals).
12. There have been incidents of thrombosis or embolism occurring within the first 6 months of treatment, such as cerebrovascular accidents (including transient ischemic attacks, cerebral hemorrhage, cerebral infarction), pulmonary embolism, etc.
13. Participants with a history of gastrointestinal bleeding or a clear tendency towards gastrointestinal bleeding within 6 months prior to the start of the study treatment, such as those at risk of bleeding or severe esophageal and gastric varices, locally active gastrointestinal ulcer lesions, or continuous positive fecal occult blood, cannot be included in the study. (If fecal occult blood is positive during the baseline period, a follow-up examination is required. If the follow-up examination is still positive, gastroduodenoscopy (EGD) is required. If EGD indicates a risk of bleeding, esophageal and gastric varices/other gastrointestinal diseases cannot be included in the study.)
14. Within 6 months prior to the start of treatment, there have been abdominal fistulas, gastrointestinal perforation, or abdominal abscesses.
15. Severe, unhealed or cracked wounds, as well as active ulcers or untreated fractures.
16. Known genetic or acquired bleeding (such as coagulation dysfunction) or thrombotic tendencies, such as in hemophilia participants; Currently or recently (within 10 days prior to the start of research treatment), full dose oral or injection anticoagulants or thrombolytic drugs (prophylactic use of low-dose aspirin, low molecular weight heparin allowed) have been used for therapeutic purposes.
17. Major vascular diseases (such as aortic aneurysm requiring surgical repair or recent peripheral arterial thrombosis) occur within 6 months prior to the surgery.
18. Severe infection within 4 weeks prior to the surgery, including but not limited to hospitalization due to complications of infection, bacteremia, or severe pneumonia; Oral or intravenous administration of therapeutic antibiotics within 2 weeks prior to the start of the study treatment (subjects who receive prophylactic antibiotics, such as preventing urinary tract infections or exacerbation of chronic obstructive pulmonary disease, are eligible to participate in the study).
19. Use immunosuppressive agents or systemic hormone therapy within 14 days prior to the surgery to achieve immunosuppressive effects (dose\>10mg/day prednisone or other therapeutic hormones).
20. Received attenuated live vaccine treatment within 28 days prior to the surgery.
21. According to the judgment of the researchers, the subjects may have other factors that may affect the research results or cause the study to be terminated midway, such as alcoholism, drug abuse, other serious illnesses (including mental illness) that require concurrent treatment, serious laboratory test abnormalities, and family or social factors that may affect the safety of the subjects.
