Fact-Check Log
Every quote and paraphrase in the original notes was checked against the extracted PDF text. Full results below.
Verified accurate (verbatim or numerically correct)

- Matteucci et al - ICG vs Tc-99m Meta-Analysis — conclusion verbatim
- Lese et al - Transcutaneous ICG Sensitivity Study — BMI >30 → reduced sensitivity, statistically significant, confirmed
- Goh and Dauway - Synchronous Contralateral Axillary Metastasis (BMJ Case Report) — quote verbatim

- Sato et al - Altered Lymphatic Drainage Patterns in Re-SLNB (Radiotherapy Effect) — RT correlation confirmed (60%→93%), hedge can be dropped
- Correspondence Exchange on Vyas et al 2025 — all cited stats (29 patients, 100/85/80%, 7.1%) confirmed against the primary paper
Corrected
1. Patient count in Chowdhury et al.
Was: 1300. Actual: 1308 consecutive patients.
2. “21% at the back” — wrong number attached to wrong finding
Was: “Most relevant location was at the back. 21%.”
Actual: 21.4% (3/14) is the melanoma recurrence rate within the contralateral-drainage subgroup, not a location frequency. Real location split: left lower back 4, right lower back 2, right upper back 4 → 10/14 (71%) posterior torso, 6/14 (43%) specifically lower back.
See Chowdhury et al - Truncal Melanoma Contralateral SLN Drainage Prevalence3. Ultrasound recommendation, misattributed purpose
Was: “suggest using US to measure the lymph node size.”
Actual: the letter recommends lymphatic ultrasound to assess vessel patency/obstruction and dilation (from raised intraluminal pressure) — not node size.
See Jitworawisut and Tsukuura - Letter on Intraluminal Pressure Hypothesis
Calibrate / rephrase
4. “Lymph node generation happens in a month”
Kwon et al.’s mouse model does not show new lymph nodes forming — nodes don’t regenerate once excised. It shows lymphatic vessel regeneration and co-opting of pre-existing collateral vessels, with contractile function restored by day 13. Rephrase as “collateral vessel recruitment,” not “node generation.”
See Kwon et al - Lymphatic Contractility and Drainage After Lymphadenectomy (Mouse Model)5. Heydon-White overstated
Note states ICG “is effective” for breast lymphoedema assessment; the paper frames this as a pilot study and a “potential” qualitative technique. Keep the hedge if cited.
See Heydon-White et al - ICG Lymphography for Breast Lymphoedema6. “29 patients” — precise but narrow
Accurate for the pre-planned ICG-only group in Vyas et al., but 2 more patients became ICG-only-by-necessity after radiocolloid failure (31 total ICG-only experience). Not wrong, just know the nuance if a reviewer asks.
