MSLT-II
A Phase III Multicenter Randomized Trial of Sentinel Lymphadenectomy and Complete Lymph Node Dissection Versus Sentinel Lymphadenectomy Alone in Cutaneous Melanoma Patients With Molecular or Histopathological Evidence of Metastases in the Sentinel Node
- NCT00297895 ↗
- v1.0.0 · edition 1
- updated Oct 8, 2026
- Standard
MSLT-II centers on whether patients with skin melanoma and a positive sentinel node, but no clinically apparent nodal disease, need further node surgery or can instead undergo ultrasound surveillance. Clinicians discuss survival and regional control, surgical harms, ultrasound expertise and access, CT/PET imaging, adjuvant-treatment evidence and toxicity, transplant-related risks, microscopic deposits and pathology, sentinel-node biopsy’s role, site-specific applicability, patient preferences, and follow-up coordination.
Findings
12 findings · titles free- 01
Avoiding routine completion dissection is the leading reading, but regional control and selective exceptions remain
- 02
Clinical nodal presentation is a critical boundary; imaging can make that boundary less straightforward
- 03
Expert ultrasound and reliable follow-up are conditions of de-escalation, but routine ultrasound alongside CT/PET is contested
Sample finding · freeAn X thread asked what extra value routine nodal ultrasound offers for sentinel-node-positive patients already receiving CT/PET surveillance.

- 04
Omitting dissection does not settle the adjuvant-treatment decision, particularly in lower-risk disease
Sample finding · freeA podcast speaker asked what benefit adjuvant PD-1 therapy offers in stage III melanoma when completion lymph-node dissection has been omitted.
Source: podcast, 2024-12-10 · paraphrased; the full report links the source
- 05
Transplant-related constraints can produce a different local-treatment choice without proving a dissection benefit
- 06
The completion-dissection result is not read as a reason to abandon sentinel-node biopsy
- 07
Follow-up intensity is pragmatic and risk-sensitive; benefit from earlier systemic treatment remains an open question
- 08
Imaging should change a decision, but baseline timing and postoperative interpretation can also delay care
- 09
Surgical morbidity is a major rationale, but its weight varies by basin, occupation, and patient circumstances
- 10
Head-and-neck and vulvar discussions retain site-specific qualifications rather than a blanket extrapolation
- 11
Small deposits, assay differences, and nonsentinel-node ascertainment complicate risk interpretation
- 12
Implementation includes institutional variation, patient preferences, care ownership, and research infrastructure
The full report gives each finding its interpretation, the attributed views behind it, counterviews, limits and the verified claims with exact source passages.
How should Medical Affairs distinguish survival, regional-control, prognostic-information, and morbidity considerations in explanations of surgical de-escalation?
Raised by the leading finding. The report shows what clinicians said and the sources behind it; it does not settle the question.

Scope and limits
freeThis report does not judge efficacy, estimate HCP prevalence or consensus or give treatment advice.
- Sources were found by searching for the trial's name, registry number and known aliases. Discussion that refers to the trial without naming it may be missing.
- For 6 recordings, a transcript separated by speaker was not available, so quotes come from the original automatic transcript and may lack speaker labels.
- 2 cited commentary passages leave a source question open, such as who was speaking. The report attributes no further than the source shows.
- 34 points raised by the independent review are not yet resolved in this edition, such as a clinician view not yet captured as evidence or a qualifier to restore. The next refresh takes them up.
- 3 further source limits are recorded in the machine-readable scope of this record.
- The reviewed material is not representative of all clinicians or all public commentary. Additional potentially relevant recordings were unavailable, and unnamed or differently transcribed trial references may be missing.
- Overlapping releases and podcast/video versions cannot be counted as independent HCP opinions. Source volume does not establish consensus.
- Some passages do not establish who spoke. Their full views remain attributed to unnamed speakers rather than to people listed in programs or participant information.
- Some transcript wording remains uncertain. The low-volume immunotherapy passage does not establish whether treatment is omitted or administered, and the case summary does not clearly establish steroid exposure.
- Reported guideline positions, approval access, study eligibility, endpoint summaries, and practice changes are dated speaker accounts unless expressly identified as verified contextual reporting. Differing retellings have not been silently reconciled.
- Individual cases, small series, retrospective comparisons, biological hypotheses, and speculative subgroup explanations do not establish comparative efficacy or a surgery-benefit subgroup.
- The complete later regional-control publication was unavailable; its supplied context should not be read as a complete assessment of that publication.
- Professional profiles provide context, not passage attribution or additional evidentiary weight. Meredith Gunder, MD's clinical role is unresolved in the supplied professional context.
