Gastric Pathology Specialist
Complete gastric cancer pathology workflow toolkit combining compliance checking, staging, HER2 reporting, and coding.
When to Use This Skill
Use this skill for:
- Gastric cancer pathology report validation
- Gastric carcinoma specimens (gastrectomy, endoscopic resection)
- CAP/ICCR compliance checking with severity scoring
- TNM staging calculation (AJCC 8th edition)
- Lauren classification (intestinal/diffuse/mixed)
- WHO histologic typing
- HER2 testing interpretation (IHC/FISH)
- Tumor board summary generation
- SNOMED CT coding assistance
Supported Specimen Types
- Total gastrectomy
- Subtotal/partial gastrectomy
- Proximal gastrectomy
- Endoscopic mucosal resection (EMR)
- Endoscopic submucosal dissection (ESD)
- Wedge resection
Key Features
- Compliance Checking: Validates against CAP Stomach and ICCR Gastric Carcinoma protocols
- TNM Staging: AJCC 8th edition gastric cancer staging with pT/pN/M calculation
- Lauren Classification: Intestinal, diffuse, mixed, or indeterminate type
- WHO Typing: Tubular, papillary, mucinous, poorly cohesive, mixed adenocarcinoma
- HER2 Reporting: IHC scoring (0/1+/2+/3+) and FISH interpretation per Trastuzumab guidelines
- Template Generation: Gastrectomy and endoscopic resection synoptic templates
- Tumor Board Summaries: Concise 3-5 line MDT presentation format
- SNOMED Coding: Gastric-specific code suggestions
Reference Files
When processing reports, reference these files on-demand (DO NOT load at startup):
- Diagnosis guidelines:
references/diagnosis/gastric_carcinoma.md
- Macroscopy guidelines:
references/macroscopy/gastric_macroscopy.md
- TNM staging:
../../shared-references/staging/tnm_stage_calculator.md
- Synoptic templates:
../../shared-references/templates/synoptic_templates.md
- Biomarkers:
../../shared-references/biomarkers/BIOMARKERS_INDEX.md
- SNOMED codes:
../../shared-references/coding/snomed_ct_codes.md
Usage Examples
# Validate report compliance
claude "Check this gastric report using gastric-pathology-specialist" < report.txt
# Generate staging
claude "What stage is pT3 N2 M0 for gastric using gastric-pathology-specialist"
# Create template
claude "Generate total gastrectomy template using gastric-pathology-specialist"
# HER2 interpretation
claude "Interpret HER2 IHC 2+ and FISH ratio 2.3 using gastric-pathology-specialist"
Processing Instructions
When analyzing gastric pathology reports:
- Identify request type (compliance check, staging, template, HER2 interpretation, summary, coding)
- Read relevant reference file on-demand based on request
- Process the report using appropriate guidelines
- Generate output in requested format
- DO NOT load all reference files upfront
Compliance Scoring
Use severity-based weighting:
- Critical elements (tumor size, grade, depth, margins, nodes, HER2): -15 points each
- Major elements (LVI, PNI, Lauren type, WHO type): -5 points each
- Minor elements (tumor location, distance from margins): -2 points each
Scoring: 90-100 (Compliant) | 70-89 (Minor issues) | 50-69 (Major issues) | <50 (Critical)
Cross-Validation Checks
Always validate:
- pT category vs invasion depth (mucosa/submucosa/muscularis propria/serosa)
- pN category vs positive node count
- Stage group vs pT/pN/M combination
- Margin status vs R classification
- HER2 IHC vs FISH correlation (2+ requires FISH)
Language Support
Supports English and Turkish - detect from user prompt and use appropriate template file.
Note: This is a minimal skill definition. Large reference files are loaded on-demand only when processing requests, not at skill startup.
1---2name: gastric-pathology-specialist3description: Comprehensive gastric cancer pathology workflow combining CAP/ICCR compliance validation, synoptic template generation, TNM staging (AJCC 8th edition), Lauren classification (intestinal/diffuse/mixed), WHO histologic typing, HER2 testing interpretation per ASCO/CAP, MSI/MMR status, tumor board summaries, and SNOMED coding. Use when the user uploads or pastes a gastric pathology report (total/subtotal gastrectomy, esophagogastrectomy, endoscopic submucosal dissection) and asks to "check gastric report", "validate CAP Stomach protocol", "stage this gastric cancer", "interpret Lauren classification", "interpret HER2 IHC/FISH", or any gastric-cancer-specific pathology task.
