What is langcare-oncology?

A clinical timeline builder for cancer care using FHIR, a standard format for exchanging healthcare data. It organizes diagnosis, cancer stage, treatments, laboratory results, reports, and treatment response by date.

Use it to summarize TNM staging, chemotherapy, immunotherapy, surgery, radiation, tumor-marker trends, blood tests, imaging or pathology reports, and response assessments.

It turns scattered oncology records into a chronological view that is easier to review.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00070	$0.00867
Opus 5	$0.00035	$0.00434
Sonnet 5	$0.00014	$0.00173
Haiku 4.5	$0.00007	$0.00087

Security

Grade A, and why

langcare-oncology scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Oncology Treatment Timeline

When to Use This Skill

Use when a clinician needs a comprehensive cancer care timeline including staging, treatment history, lab trends, and response assessment.

Clinical Workflow

Use fhir_read to retrieve Patient demographics
Use fhir_search to pull cancer Condition resources with staging information (TNM, clinical stage, pathologic stage)
Use fhir_search to pull Procedure resources for surgical interventions (biopsy, resection, radiation)
Use fhir_search to pull MedicationRequest/MedicationAdministration for chemotherapy, immunotherapy, targeted therapy, hormonal therapy
Use fhir_search to pull Observation resources for tumor markers (PSA, CEA, CA-125, CA 19-9, AFP, HCG) and lab trends (CBC for myelosuppression, LFTs, renal function)
Use fhir_search to pull DiagnosticReport for pathology and imaging reports
Organize into chronological treatment timeline with staging at diagnosis and response assessments (see references/tnm-recist-staging.md)
Present: diagnosis summary, staging, treatment phases with dates, current regimen, tumor marker trends, key lab monitoring, and response status

FHIR Resources

Condition -- Cancer diagnosis with staging: code (ICD-10/SNOMED), stage (TNM), onsetDateTime
Procedure -- Surgeries, biopsies, radiation therapy
MedicationRequest / MedicationAdministration -- Chemotherapy, immunotherapy, targeted therapy
Observation -- Tumor markers, CBC, metabolic panel
DiagnosticReport -- Pathology reports, imaging (CT, PET, MRI)

FHIR Query Examples

Pull Cancer Conditions

fhir_search(resourceType="Condition", queryParams="patient=[patient-id]&category=encounter-diagnosis&code=http://snomed.info/sct|363346000")

Pull Tumor Markers (PSA example)

fhir_search(resourceType="Observation", queryParams="patient=[patient-id]&code=2857-1&_sort=date&_count=20")

Pull Treatment History

fhir_search(resourceType="MedicationAdministration", queryParams="patient=[patient-id]&_sort=date&_count=200")

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

langcare-oncology is a skill published in the GitHub repository langcare/langcare-mcp-fhir (55 stars, last pushed 5mo ago), licensed MIT. It adds 70 tokens to every session and 867 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
