arXiv:2608. 13711v1 Announce Type: cross Abstract: Computer-aided detection (CADe) systems for colonoscopy promise to reduce clinical miss rates, yet reliable real-world deployment remains elusive.

Progress in colonoscopy polyp segmentation is routinely reported through leaderboard comparisons on a small set of public benchmarks. We argue that this apparent progress is difficult to verify: a systematic audit of \textbf{27 papers} published between 2015 and 2026 reveals three structural problems in how the community evaluates models.
The study investigates how few expert-annotated cases are needed to fine‑tune MedSAM3 for abdominal organ segmentation using Low‑Rank Adaptation (LoRA). With only 10 annotated CT or MRI cases, the LoRA‑adapted models achieve performance comparable to specialist systems that require orders of magnitude more data, including reliable gallbladder segmentation and near‑state‑of‑the‑art results for liver, kidneys, and spleen. The approach also generalizes to cardiac segmentation on the Whole Heart dataset, and training takes only 3–5 hours per organ on a single GPU, roughly twice as fast as nnU-Net.
This paper reports a fully localized, low‑resource framework that runs a trillion‑parameter biomedical large language model on a single consumer‑grade RTX 4060 laptop (32 GB system memory, 8 GB VRAM) and routine clinical workstations. The system completes an entire tumor‑paired whole‑genome sequencing workflow—from raw FASTQ input to a clinical‑grade full‑variation‑spectrum report—in 18 hours at 30× depth, achieving a 99.62 % F1 score for somatic variant detection and over 99.9 % concordance with an industrial‑standard A100 cluster pipeline. The study demonstrates that adaptive heterogeneous memory scheduling accounts for 71 % of execution time and that model optimization adds less than 9 % of detection error, establishing a low‑cost, high‑accuracy pathway for global primary medical institutions to adopt precision oncology without expensive GPU clusters.
