It replaces (repeals) the earlier 2011 SoP for malignant neoplasm of the liver (see section 4). It commenced on 25 May 2020 (section 2).\n\n- The instrument defines the medical condition covered: **malignant neoplasm of the liver** (primary cancer of hepatocytes, commonly called hepatocellular carcinoma) and death from that condition (section 7(2), (5)). It excludes certain other tumours and lymphomas (section 7(2)(b)).\n\n- It lists the medical, lifestyle and exposure **factors** such that, if at least one factor existed in a person and was related to their relevant service, a “reasonable hypothesis” can be raised that the condition is related to service (sections 8–10 and section 9). In other words, the presence of any one of the enumerated factors (together with the link to relevant service) is the minimum evidentiary threshold for considering the diagnosis to be service‑related for claims under the VEA or the MRCA (section 5).\n\n- The list contains 27 separate factors (section 9). They include: pre‑existing cirrhosis; chronic viral hepatitis (B, C, D); HIV infection; chronic hepatitis; long‑standing diabetes; obesity/overweight; quantified alcohol consumption; quantified tobacco use; measured ionising radiation dose to the liver; systemic immunosuppression after transplantation; long‑term dietary aflatoxin exposure; measured occupational exposures (vinyl chloride, asbestos, arsenic); prolonged physical inactivity (METs); use of combined oral contraceptives; anabolic‑androgenic steroid use (with dose and duration thresholds); betel quid/areca nut chewing; steatohepatitis; certain autoimmune or specified metabolic liver disorders; and inability to obtain appropriate clinical management (see section 9 and Schedule 1 definitions).\n\n- Many factors have technical thresholds and timing conditions (for example: minimum cumulative doses, minimum durations, latency periods of at least 5 or 10 years before clinical onset, and time limits after cessation for some exposures — see section 9 and Schedule 1). The instrument also cross‑refers to other SoPs when a listed factor is itself an injury/disease already covered by another SoP (section 11).\n\n**Who this affects**\n\n- Primary effect: veterans and former members of the Australian Defence Force (and members of Peacekeeping Forces or Forces covered under the MRCA) who lodge claims under the VEA or MRCA for primary liver cancer or death from it (section 5).\n\n- Secondary effects: medical practitioners and forensic/occupational clinicians who supply the clinical and exposure evidence to support claims; decision makers in the Department administering veterans’ entitlements who apply the SoP to individual claims; and, indirectly, employers or third parties where workplace exposures (e.g. asbestos, vinyl chloride, arsenic) are relied on as the relevant cause.\n\n**Why it matters (purpose claim and operational effect)**\n\n- The RMA states that there is sound medical‑scientific evidence that malignant neoplasm of the liver can be related to relevant service (section 8). The practical effect is to set an objective list of factors which, if present and related to service, meet the statutory threshold of a “reasonable hypothesis” that the condition is service‑related. That threshold governs whether entitlement claims proceed to a merits assessment for compensation/benefits under the VEA/MRCA.\n\n**Testing the purpose‑claim against costs, incentives and implementation trade‑offs**\n\n- Evidence burden and proof: many listed factors require objective clinical or laboratory confirmation (e.g. chronic viral infections confirmed by serology or nucleic acid testing; documented cumulative radiation dose; measured BMI; quantified alcohol/tobacco consumption). This shifts the evidentiary work onto claimants and their treating clinicians to produce historical, laboratory and exposure records (see section 9 and Schedule 1). Where exposures are occupational or remote in time, reconstructing them can be difficult and costly.\n\n- Administrative burden on decision makers: the Department will need to assess whether a listed factor existed and whether it was related to the person’s relevant service. For technical factors (ppm‑years, sieverts, cumulative asbestos hours) the Department may require specialist occupational hygiene or dose reconstruction input. That increases processing complexity and cost for adjudicators and may extend claim timelines.\n\n- Concentrated benefits, diffuse costs: the direct beneficiaries are claimants who can marshal evidence of any listed factor. The costs (administrative, medical documentation, and potential payments) are borne by the veterans’ compensation system and, indirectly, taxpayers. Where workplace exposures are relied upon, employers or liability schemes might face follow‑on claims outside this SoP, but the SoP itself governs veterans’ entitlements rather than employer liability.\n\n- Behavioural incentives: claimants and clinicians will tend to emphasise and document the listed factors in building claims (for example, ordering hepatitis serology, documenting alcohol/tobacco history, or obtaining occupational exposure histories). The SoP creates a predictable list of routes into a successful reasonable hypothesis finding, which reduces uncertainty about what evidence is material.\n\n- Risk of substitution and evidentiary gaps: some relevant causal pathways for liver cancer (for example, multifactorial metabolic disease) may involve combinations of weaker factors rather than a single dominant factor. The SoP requires at least one listed factor (section 9), which can both simplify adjudication and risk overlooking causation where no single enumerated factor is clearly present but the totality of risk is increased.\n\n- Bureaucratic discretion and cross‑reference risk: the RMA sets the medical criteria, but the determination whether the factor is “related to relevant service” (section 10) is an administrative decision; the SoP’s cross‑reference rule (section 11) requires decision makers to consult other SoPs when a factor overlaps another listed injury/disease, which adds layers of cross‑checking.\n\n**Key implementation details to watch**\n\n- Many factors carry technical thresholds (pack‑years, kg alcohol over time, sieverts, ppm‑years, cumulative asbestos hours, BMI, durations and latency requirements). These need precise evidence and, in some cases, specialist reconstruction (section 9; Schedule 1 definitions).\n\n- The instrument updates references (e.g. ICD‑10‑AM code and methodology for cumulative equivalent dose) and supplies definitions (Schedule 1) that control how the factors are applied in practice (sections 7(3)–(4); Schedule 1).\n\n**Who pays and who decides**\n\n- The RMA sets the medical rules; Departmental administrators and review bodies apply them to individual claims and decide on entitlement. Costs of evidence collection (tests, specialist reports) are generally borne by claimants or by public health providers; final compensation/benefit payments are funded through the veterans’ entitlements framework (VEA/MRCA).\n\n**Bottom line (mechanical effect)**\n\n- This SoP replaces the 2011 version and supplies a modernised, enumerated list of medical, lifestyle and exposure factors (with thresholds and timing rules) that, if present and linked to relevant service, raise a reasonable hypothesis that primary liver cancer or death from it is related to service. It therefore standardises the medical threshold used to admit such claims to merits assessment under the VEA and MRCA (sections 4–11)."},"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
