AI Article Synopsis
- The study analyzed preoperative lymph node involvement in cervical cancer by reviewing 155 cases, correlating results with lymph node histology.
- Only one of the 103 patients who underwent lymphography had accurate detection of lymph node involvement, reflecting a sensitivity of 33% and a specificity of 67%, with two false positives identified.
- MRI did not perform better than lymphography in detecting lymph node involvement, as all cases were classified as nodal negative despite the poor performance of lymphography.
Article Abstract
In this study the preoperative staging of lymph node involvement in cervical cancer was analyzed retrospectively in 155 cases. All results were correlated with lymph node histology. One hundred and three patients underwent preoperative lymphography. Twelve of them were investigated by lymphography and MRI (magnetic resonance imaging). One patient was staged Ia, 10 patients were staged Ib and one patient was staged IIb. All patients underwent surgery; 18.5 lymph nodes were removed on average. Histologically lymph node involvement was found in 3 cases. Lymphography was able to detect lymph node involvement correctly in one case (33% sensitivity). We got two false positive results by lymphography (67% specificity). By MRI all cases were classified as nodal negative. MRI did not have advantage over bipedal lymphography in detecting lymph node involvement in our study, even though the results of lymphography were also poor.

Prognostic value of immune biomarkers in melanoma loco-regional metastases.

The prognosis for patients with melanoma loco-regional metastases is very heterogenous. Adjuvant PD-L1-inhibitors have improved clinical outcome for this patient group, but the prognostic impact of tumour PD-L1 expression and number of tumour infiltrating lymphocytes (TILs) is still largely unknown. Here, we investigated the impact on survival for CD3, CD8, FOXP3 and PD-L1 TIL counts and tumour PD-L1 expression in melanoma loco-regional metastases.

Purpose: To evaluate the diagnostic accuracy and clinical impact of fibroblast activation protein (FAP)-targeted PET/CT imaging in primary and metastatic breast cancer and compare the results with those of standard-of-care imaging (SCI) and [F]FDG PET/CT.
Methods: We prospectively analyzed patients with diagnosed or suspected breast cancer who underwent concomitant FAP-targeted PET/CT (radiotracers including either [Ga]Ga-FAPI-46 or [F]FAPI-42) and [F]FDG PET/CT scans from June 2020 to January 2024 at two medical centers. Breast ultrasound (US) imaging was performed in all treatment-naïve patients as SCI.

This study aimed to characterize Salmonella and Yersinia enterocolitica detected in fattening pigs in Sardinia, examining genetic similarity and antimicrobial resistance of isolates from farms and slaughterhouses and evaluating carcass hygiene. Environmental samples were collected from six pig farms, and the same pigs were also sampled at the slaughterhouses. Palatine tonsils, mesenteric lymph nodes, colon content, and carcass surface samples were collected and tested for Salmonella and Y.

Malignant adenomyoepithelioma (MAME) of the breast is a rare tumor with both benign and malignant features. We report a case of a 67-year-old woman who presented with a mass in the outer quadrant of the right breast, detected during a routine check-up. The mass was classified as BI-RADS 3.
