Abstract

fetched live from OpenAlex

Cancer recurrence in surgical wounds occurs by unknown mechanisms. My hypothesis is that tumour cells are harboured on surgical gloves and instruments during the extirpative phase of a cancer resection and can exfoliate into the wound during reconstruction, with potential for growth. A systematic review revealed that the incidence of port-site metastasis in gallbladder cancer is especially high. A survey of practising surgeons found that there is no consensus as to whether specific intraoperative protective strategies are warranted. An analysis of washings from gloves and instruments used intraoperatively during cancer resections identified malignant cells on approximately half of gloves and instruments that had directly handled malignant tissue (debulking of peritoneal malignancy, incisional biopsy of extremity sarcoma). No malignant cells were identified on a glove or instrument used in margin-negative sarcoma resection. These results suggest that specific protective strategies may not be warranted in curative resections.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
