The Industry’s First AI Trust Stack for Precision Oncology

One agentic platform: it unifies the patient record, simulates the best-fit therapy before a single dose,, and secures every output behind your firewall. Compliance, Governance and Evaluation agents validate each recommendation, so it reaches care explainable, traceable and governed.

EXPLAINABLE TRACEABLE GOVERNED

AI Orchestration for Cancer Platform

The gSage agentic stack coordinates every agent, tool and data source so the whole system reasons as one, moving cancer AI from decision support to decision intelligence.

A

AI Agents

Deep Research, Digital Twin, Monitoring and Pre-Auth master agents, each orchestrating scoped sub-agents up the stack.

D

Data Sources and Tools

EHR, labs, genomics, imaging and devices, reached in place via governed MCP servers behind the firewall.

R

RAG + Knowledge Graphs

Retrieval over the cancer oncology and patient-graph models brings the right context to every decision.

L

Loop Engineering

Input, reasoning, treatment, outcome, recalibration. Each closed loop makes the next recommendation sharper.

Every Patient Makes the Next One Sharper

Data flows continuously from EHRs, labs and cancer repositories into the agentic layers, and because each pass derives new structured data, the record deepens and the engines improve with every patient.

Calls variants, derives signatures (HRD, MSI), computes pathway-level scores against curated knowledge bases.

The OncoLLM family reads across years of record; annotation agents label every element against a purpose-built cancer ontology, making the data AI-workflow-ready.

The unified, cited record feeds the Digital Twin, Deep Research, Monitoring and Pre-Auth agents, clinical, administrative and research workflows all reading from one source of truth.

Live ctDNA and IoT data plus realized outcomes flow back to recalibrate the twin and retrain the engines.

Validation That Never Stops

Evaluation agents score every output against ground truth and guidelines on live dashboards, while the GeneSilico AI Agent Simulator proves each response through a full rules-and-safety gauntlet before it reaches care.

EVERY SIMULATED RESPONSE IS VALIDATED AGAINST ›››
01

Onco Rules

Conforms to NCCN / ASCO guidelines for this tumor and line.

02

Patient Compliance

Safe for this patient: comorbidities, consent.

03

Treatment Accuracy

Holds up against real outcomes, calibrated.

04

Security

Every access in-policy, free of injection or tampering.

HOW IT RUNS ›››

Continuous evaluation

Live accuracy dashboards by tumor type, model and workflow, stratified across subgroups to surface disparities.

Continuous training

Realized outcomes and reviewer feedback return to the engines; reliability improves with every case the platform sees.

Judge and Jury
for Every Output

Independent agents cross-examine every output against cited evidence and each other, catching unsupported content before it reaches care.

Compliance

Checked against HIPAA, HL7/FHIR and regulatory obligations, built into the architecture, not asserted after.

Cancer Guideline Adherence

Corroborated against NCCN, ASCO and cited source evidence, so what surfaces is grounded and defensible

Clinical Policy

Each provider's own policies and formularies are enforced, so outputs match how this institution practices

Bias Detection

Individual clinician biases are surfaced and checked, keeping recommendations equitable.

HOW IT WORKS

Judge and Jury agents independently cross-examine each output, while Observation Agents preserve the full lineage of inputs, reasoning steps, models invoked and evidence cited. A clinician sees not only what GeneSilico recommends, but exactly why, auditable end to end for tumor boards, registries and regulators.

Every Agent Runs
Under Control

A live control plane that governs how every agent runs, tracking identity, enforcing data access by policy, and stopping the adversarial attacks that target agentic systems handling patient data.

Every Agent Runs Under Control
ID

Agent Identity
and Registration

  • Registered, allow-listed agents only
  • Runtime-enforced YAML policy contract
  • Non-compliant agents quarantined
SEC

Security Scanning
and Data Access

  • Every call checked against policy
  • Scans reachable MCP data sources
  • Gateway logs every prompt and access
DEF

Attack Defense

  • Prompt-injection detection
  • Memory-poisoning prevention
  • Runtime quarantine on any risk

Trustworthy AI in oncology will not be the model with the most data, but the one that can prove, explain and govern every decision it makes for a patient.

Start with a pilot.
Scale with confidence.

A typical 60–90 day pilot stands up Casebook, the Cancer Digital Twin and the full AI Trust Stack behind your firewall establishing reliability, security and accuracy before scale.
