Etiological driver

Etiological driver · etiologically_driven archetype

Kaposi sarcoma

HHV-8 / KSHV (Kaposi sarcoma-associated herpesvirus) — IARC Group 1 carcinogen; obligate etiology
HIV-related immunocompromise (AIDS-defining malignancy)
Iatrogenic immunosuppression (solid-organ transplant recipients; post-transplant tumor regression with mTOR-inhibitor conversion is documented)
Classic (Mediterranean / elderly male) form — HHV-8 prevalent regions
Endemic (sub-Saharan African) form — HHV-8 prevalent without HIV

Primary current-line option

Standard plan

★ DEFAULT

Indication

IND-KAPOSI-1L-IATROGENIC-MTOR-CONVERSION

Regimen

Sirolimus conversion (iatrogenic/transplant-associated Kaposi sarcoma)

Drugs + NSZU

Sirolimus (DRUG-SIROLIMUS) Per transplant-team protocol -- typically initiated at low dose (e.g. 1-2 mg PO once daily) and titrated to institutional/transplant-program target trough level while the calcineurin-inhibitor component of the immunosuppression regimen is tapered · Continuous; conversion performed under transplant-team supervision with graft-function monitoring · PO ⚠ Out-of-pocket

Reason

Primary current-line option selected by ALGO-KAPOSI-1L at step 3.

Other current-line alternatives (3 tracks)

Same treatment line; review when biomarker, access, contraindication, or patient-context assumptions change.

Standard plan

Indication

IND-KAPOSI-1L-AIDS-ART

Regimen

Biktarvy — bictegravir/emtricitabine/tenofovir-AF single-tablet ART

Drugs + NSZU

Bictegravir / Emtricitabine / Tenofovir alafenamide (DRUG-BICTEGRAVIR-EMTRICITABINE-TENOFOVIR-AF) 50/200/25 mg PO (single tablet) · once daily, with or without food · PO ⚠ NSZU — not for this indication

Reason

Current-line alternative presented for HCP consideration

Local therapy plan

Indication: IND-KAPOSI-1L-CLASSIC-LOCAL-OBSERVATION
Regimen: —
Reason: Current-line alternative presented for HCP consideration

Standard plan

Indication

IND-KAPOSI-1L-VISCERAL-PLD

Regimen

Pegylated liposomal doxorubicin monotherapy (Kaposi sarcoma)

Drugs + NSZU

Pegylated liposomal doxorubicin (DRUG-PEGYLATED-LIPOSOMAL-DOXORUBICIN) 20 mg/m² IV every 2-3 weeks · Day 1 of each 14-21 day cycle · IV ⚠ Out-of-pocket

Reason

Current-line alternative presented for HCP consideration

Red flags — PRO / CONTRA aggressive

PRO-AGGRESSIVE

Triggers that push toward the aggressive track

Visceral organ involvement (pulmonary, gastrointestinal, or other visceral site) OR extensive/rapidly progressive mucocutaneous disease (widespread cutaneous lesions, tumor-associated lymphedema, or ulceration) in Kaposi sarcoma of any epidemiologic form (AIDS- associated, iatrogenic, classic, or endemic). Symptomatic/extensive disease of this kind is not expected to be adequately controlled by immune restoration (ART / immunosuppression rebalance) or local therapy alone and drives escalation to systemic chemotherapy.
New disease-extent gate authored for the DIS-KAPOSI treatment pathway (v0.3 continuation -- closes the "missing TREATMENT-intent Indications" gap). Distinct from the pre-existing PREVENTION-persona RF-CHRONIC-HHV8-MALIGNANCY-PREVENTION…
RF-KAPOSI-VISCERAL-EXTENSIVE-DISEASESRC-NCCN-SKIN-2025SRC-NIH-AIDS-2024

CONTRA-AGGRESSIVE

Hard contraindications to escalation

What NOT to do

Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity

Standard plan (IND-KAPOSI-1L-IATROGENIC-MTOR-CONVERSION)

Do not change a transplant recipient's immunosuppression regimen unilaterally, without transplant-team consult.
Do not use mTOR-inhibitor conversion as sole therapy for visceral or extensive disease.
Do not discontinue immunosuppression entirely -- the goal is rebalancing, not withdrawal.

Standard plan (IND-KAPOSI-1L-AIDS-ART)

Do not use ART as sole therapy for visceral or extensive disease -- added systemic chemotherapy is required.
Do not interrupt ART during any subsequent cancer treatment without an HIV-specialist consult.
Do not skip drug-drug interaction screening before adding any cancer treatment.

Local therapy plan (IND-KAPOSI-1L-CLASSIC-LOCAL-OBSERVATION)

Do not skip histologic confirmation and exclusion of HIV-associated / iatrogenic forms before choosing an observation strategy.
Do not use systemic chemotherapy as first-line therapy for limited cutaneous classic/endemic disease.
Do not ignore signs of progression -- reassess against IND-KAPOSI-1L-VISCERAL-PLD.

Standard plan (IND-KAPOSI-1L-VISCERAL-PLD)

Do not interrupt ART during PLD chemotherapy for the AIDS-associated form.
Do not change a transplant recipient's immunosuppression without transplant-team consult, even during chemotherapy.
Do not skip baseline and serial LVEF assessment -- cumulative anthracycline cardiotoxicity risk.
Do not dilute PLD in normal saline -- disrupts the liposomes; D5W only.
