Hypopharynx (HC: pyriform fossa, postcricoïd area, and posterior wall) and lateral epilarynx carcinomas (LEC: aryepiglottic fold, pharyngoepiglottic fold, and arytenoïd) have a high tendency to cervical lymph node invasion. Such nodal extension is a well-known prognostic factor. This study is based on a retrospective review of 884 clinical records of previously untreated HC or LEC. Seventy percent of patients revealed palpable nodes at their first examination, with a higher percentage for HC (73%) than LEC (62%). The 5-year survival rate was divided by three in the presence of contralateral, bilateral, or fixed nodes, or in cases of nodes exceeding 3 cm. Multiple positive nodes, extracapsular spread, or lower-neck positive nodes significantly decreased survival, doubled the number of neck recurrences, and tripled the number of distant metastases while control at the primary site remained unvaried.

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.

Background: Ovarian cancer (OC) represents a common neoplasm within the female reproductive tract. The prognosis for patients diagnosed at advanced stages is unfavorable, primarily attributable to the absence of reliable screening markers for early detection. An elevated neutrophil-to-lymphocyte ratio (NLR) serves as an indicator of host inflammatory response and has been linked to poorer overall survival (OS) across various cancer types; however, its examination in OC remains limited.
