UC-ONC-030: Spotlight Critical Labs

Purpose: Highlight critical oncology labs (CBC, LDH, CEA, etc.).

Property	Value
Actor	Lab Highlighting Service
Trigger	Lab result ingested
Priority	P1

Main Success Scenario:

1. Identify oncology-relevant labs
2. Flag critical values (neutropenia, thrombocytopenia)
3. Display prominently in oncology dashboard

Acceptance Criteria:

1. [ ] Covers CBC, LFT, tumor markers
2. [ ] Critical ranges configurable
3. [ ] Oncology-specific thresholds applied

UC-ONC-031: Track Tumor Markers

Purpose: Track tumor markers longitudinally (CEA, CA 19-9, PSA).

Property	Value
Actor	Tumor Marker Tracker
Trigger	Tumor marker lab result
Priority	P1

Main Success Scenario:

1. Extract tumor marker value and date
2. Plot on trend chart
3. Flag rising trends (doubling time)
4. Correlate with treatment cycles

Acceptance Criteria:

1. [ ] Supports all common tumor markers
2. [ ] Trend visualization available
3. [ ] Alerts on significant rises

UC-ONC-032: Detect Lab Red Flags

Purpose: Detect treatment-limiting toxicities.

Property	Value
Actor	Toxicity Detector
Trigger	Lab result analyzed
Priority	P0

Main Success Scenario:

1. Check for neutropenia (ANC < 500)
2. Check for thrombocytopenia (Platelets < 50k)
3. Alert care team if treatment-limiting toxicity detected

Alternative Flows:

Alt-1: Lab Below Treatment Threshold

- ANC < 1000 or Platelets < 75k (caution zone) - Alert team for monitoring - Suggest dose delay consideration

Observability:

• Metric: onc_lab_red_flag_detected, onc_toxicity_alert_sent
• Log: {"event": "toxicity_detected", "lab": "ANC", "value": 450, "threshold": 500, "patient_id": "P1234"}

Acceptance Criteria:

1. [ ] Real-time alerts
2. [ ] Thresholds per protocol
3. [ ] Escalation to oncologist
