Diagnostic accuracy and safety of ultrasound-guided percutaneous core needle biopsy among children with extra cranial solid masses at a tertiary care hospital in Karachi, Pakistan
Bibliographic record
Abstract
Objective: To determine the diagnostic accuracy and procedure safety of ultrasound-guided core needle biopsy of extra cranial solid masses in the pediatric population. Method: A cross-sectional survey was conducted by the Department of Pediatric Hematology /Oncology and Radiology at Indus Hospital and Health Network Karachi from August 2022 to April 2023. A total of 118 pediatric patients, from age one month to 18 years, with extra cranial solid masses were studied. Data was analyzed using SPSS version 24. Results: The median age of study participants was six years with IQR = 7.2 years. Among all study participants 62.7% (n=74) were male while 37.3% (44) were female. Out of all biopsies 94.07% (n=111) were conclusive and provided an accurate diagnosis of the tumor while only 5.63% (n=07) biopsies remained inconclusive. No serious post-procedure complication was reported. Pain on the site of biopsy was the most post-procedure complain reported by 34.7% (n=41) of all the study participants. Forty-two percent of the study participants never reported any post-procedure complaints after ultrasound-guided biopsy. The diagnostic accuracy was significantly higher for malignant lesions as compared to non-malignant lesions. Conclusion: Ultrasound-guided percutaneous core needle biopsy had high diagnostic accuracy and a good safety profile among children with extra cranial solid masses in private tertiary care hospital in Karachi Pakistan. doi: https://doi.org/10.12669/pjms.41.1.9777 How to cite this: Imran FA, Razaque A, Qureshi AM, Raza MR.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
