Malignant cell detection

Malignant cell detection turns Computational Biology single-cell CNV output into oncology-facing tumor biology summaries. It does not recompute copy-number signal. Instead, it consumes the CompBio single_cell_cnv handoff or result JSON and organizes malignant labels, CNV events, subclones, mutation overlap, and response features for oncology workflows.

Prerequisites

  • A completed CompBio single_cell_cnv run with oncology_handoff.json or equivalent result JSON
  • Optional mutation landscape result JSON for gene overlap with inferred CNV events
  • Optional communication or survival result JSON for downstream context

Launching the pipeline

Open the study Analyze page and use Malignant cell detection, selecting the completed CompBio CNV run (and optionally a mutation landscape run) to pull context from.

Key parameters

ParameterRequiredPurpose
cnv_result_pathYesCompBio single-cell CNV handoff or result JSON
mutation_result_pathNoCompleted mutation landscape result JSON for inferred event-gene overlap
communication_result_pathNoCompleted communication result JSON for context-aware handoff notes
survival_result_pathNoCompleted survival result JSON for outcome context

Outputs

OutputDescription
summarySource run, malignant fraction, subclone count, event count, and linked-context flags
malignant_populationsGroups called likely malignant with fraction, burden, confidence, reason, and top CNV evidence
subclone_tme_featuresCNV subclone rows prepared for communication sender grouping
cnv_eventsInferred top events carried over from the CompBio result
mutation_overlapOverlap between inferred event genes and supplied mutation/CNA result genes
survival_response_featuresFeature rows for malignant fraction, CNV burden, subclone fractions, and key inferred events
workflow_handoffsSuggested metadata columns and groupings for communication, mutation, survival, and immune workflows
caveatsResearch-use warnings from the CompBio run plus oncology interpretation caveats

The frontend result panel shows malignant populations, top CNV evidence, subclone TME handoff rows, mutation overlap, downstream feature counts, and copy buttons for summary, survival-feature, and malignant-population artifact paths.

Typical use cases

  • Review malignant clusters as tumor biology before running TME communication.
  • Stratify communication by malignant subclone sender and immune/stromal receiver.
  • Compare inferred CNV-event genes with mutation/CNA outputs.
  • Export malignant fraction, CNV burden, and subclone fractions as response or survival features.
  • Ground multi-run interpretation in CNV, immune, mutation, and outcome evidence.

Caveats

This analysis is research-only. It depends on the quality of the CompBio CNV run, especially gene order and reference-cell selection. Use DNA copy-number, mutation, histology, or orthogonal annotations where available for confirmation.
