Table 1_Case Report: Ultrasound features of pathological complete response in middle and l

A case series from figshare by Li Liang, last updated in April 2026, analyzes multimodal transrectal ultrasound features before and after neoadjuvant immunotherapy in three patients with microsatellite instability-high mid- to low-rectal cancer. The 20.0 KB document compares imaging findings with postoperative pathology results. It suggests potential ultrasound indicators for pathological complete response.

Use Cases

• Identify potential ultrasound biomarkers for pathological complete response based on described features like reduced lesion size and diminished vascularity.
• Train or validate machine learning models for radiological assessment using the comparative pre- and post-treatment feature analysis mentioned.
• Inform clinical decision-making for biopsy confirmation in cases with persistent imaging abnormalities, as discussed in the description.

Strengths

• Focuses on a novel research gap with no published studies on the topic, as stated in the description.
• Provides comparative multimodal ultrasound analysis for three specific patient cases.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Extremely small scale with only three patient cases, limiting statistical power.
• Row and column details are unknown; data structure must be inferred from the document.
• The primary data is a 20.0 KB DOCX file, which may require manual extraction for analysis.
