## 2. What the record is

Narrative **review** focused on **lung toxicity / interstitial lung disease (ILD)** associated with anti-HER2 antibody–drug conjugates (ADCs) used in breast cancer.

From the PubMed abstract (metadata only; not full-text extraction):
- Frames HER2 as prognostic and therapeutic target; ADC structure (antibody + linker + payload) aimed at reducing systemic chemo toxicity.
- Names clinically approved anti-HER2 ADCs **T-DM1 (trastuzumab emtansine)** and **T-DXd / T-Dxd (trastuzumab deruxtecan)** as efficacious in HER2-positive breast cancer.
- Emphasizes that **lung toxicity during treatment can be life-threatening**.
- States the review covers: (i) newer epidemiological features of **ILD related to anti-HER2 ADCs**, (ii) potential pathogenesis, (iii) diagnosis and treatment strategies in this field.

MeSH descriptors include: Breast Neoplasms; Immunoconjugates; Erb-b2 Receptor Tyrosine Kinases; Trastuzumab; Ado-Trastuzumab Emtansine; **Lung Diseases, Interstitial**.

**No primary trial endpoints, incidence rates, or grade-specific AE counts appear in the abstract.** Any numeric ILD rates must come from cited primary studies during later extraction — do not invent them here.

## 3. Scope decision (MUSE)

**IN SCOPE — primary fit: Safety & toxicity signals; secondary: ADC resistance context (T-DXd/T-DM1).**

Rationale:
1. Directly addresses **pulmonary toxicity / ILD** of HER2 ADCs — core MUSE safety theme (especially T-DXd ILD risk widely discussed in the programme).
2. Centers on **T-DM1 and T-DXd**, agents also central to residual-disease and metastatic HER2 pathways.
3. Review-level synthesis can map the evidence landscape and cite primary trials for subsequent claim extraction — but this screen does **not** accept review prose as primary clinical evidence.

**Not a residual-disease efficacy paper** and **not an access/equity primary source**. Still eligible via toxicity.

## 4. Screening decision

**Decision: INCLUDE for structured extraction** into the **safety** manuscript section, with caveats.

Extraction priorities (future; not done here):
- Which primary trials/cohorts the review cites for ILD incidence by agent (T-DXd vs T-DM1)
- Grading criteria, monitoring algorithms, and management recommendations — separate citation-verified claims
- Conflicts of interest / funding of the review
- Distinguish HER2-positive vs HER2-low populations if the review mixes them

**Do not** treat review narrative as decisive incidence evidence without tracing each number to a primary source.

## 5. Limitations

1. **Abstract + catalogue only**; no full-text PDF retrieved (catalogue `fullTextUrl` null).
2. **Secondary literature (Review)** — lower evidentiary weight than RCTs; useful for gap-mapping and citation harvest.
3. Title/abstract do not quantify ILD rates; epidemiology claims require full text + primary-source verification.
4. Possible overlap with other catalogue toxicity reviews (e.g., PMID 41361931 HER2 ADC toxicities; PMID 41785741 toxicity management) — deduplicate during extraction.
5. No patient advice; no cure claims; no fabricated incidence figures.

## 7. Integrity

Literature synthesis only. Prior kestrel screen (PMID 40597341, round 1491725) is a different residual-disease observational paper; this submission is a new safety-focused screen.
