Investigation of underestimated malignancy in patients with intraductal papillary tumors by core needle biopsy / 中华内分泌外科杂志

Objectives To calculate the rate of pathological underestimation for core needle biopsy (CNB)- diagnosed intraductal papillary tumors, to analyze the clinical and imaging data of patients and to dis-cuss factors for underestimation. Methods A retrospective analysis of patients undergoing core needle biopsy and subsequent surgical excision was performed. 1359 female patients undergoing CNB from Jan. 2010 to Feb. 2013 in Comprehensive Breast Health Center of Ruijin hospital were analyzed. Clinical, radiological and histo-logical variables were assessed using the Chi-square test, Fisher’s exact test and a binary logistic regression model in order to predict pathological underestimation for tumors. Results There were 50 patients with CNB-di-agnosed intraductal papillary tumors. The overall underestimation rate was about 44%(22/50). CNB-diagnosed atypical papillary lesions (OR=15.164, 95% CI 1.49-170.443) and BI-RADS 5 by MRI (OR=26.766, 95% CI 2.409-297.440)were significantly related to underestimation in these patients. Conclusions Considering the high underestimation rate in CNB-diagnosed intraductal papillary tumors, routine surgical excision should be per-formed to avoid potential malignancy, especially for patients with high risk factors. MRI is helpful in these pa-tients to predict underestimation.

Tumores quísticos del páncreas: visión quirúrgica y cohorte de pacientes / Cystic tumors of the pancreas: surgical vision and a patient cohort

Se presenta una cohorte retrospectiva de diez pacientes con tumores quísticos del páncreas, intervenidos en su mayoría – algunos por laparoscopia –, haciendo énfasis en su estudio, diagnóstico y tratamiento quirúrgico, mostrando algunas de las variables evaluadas en su manejo y con especial mención de su enfoque quirúrgico con base en una revisión sistemática de la literatura.

We present a retrospective study of a cohort of ten patients with cystic tumors of the pancreas, most of whom underwent surgery. The study emphasizes study, diagnosis, and treatment of the four who underwent laparoscopic surgery. It presents some of the variables analyzed in their management and pays special attention to their surgery treatment. A systematic review of the literature is also included.
