Objective: To evaluate the incidence and prognostic importance of micrometastatic disease in regional lymph nodes from Dukes' B colorectal carcinomas.
Design: Retrospective study.
Setting: University hospital, Sweden.
Subjects: 100 patients operated on for primary colorectal carcinoma, classified as Dukes' B lesions.
Interventions: The regional lymph nodes were re-examined immunohistochemically using monoclonal antibodies against cytokeratin.
Outcome Measures: Incidence and prognostic importance of micrometastases.
Results: Micrometastases were found in 39% (39/100) of the patients. The number of positive cells in the lymph nodes examined varied from 1 to over 100. They appeared as single cells or small clusters of cells located within the capsule or in the peripheral sinus of the lymph node. At least three sections from each of three lymph nodes had to be examined to identify 95% of the patients with lymph node micrometastases. The outcome of the patients with micrometastases was not significantly different from that of patients with no epithelial cells in the lymph nodes.
Conclusion: Micrometastases in regional lymph nodes are a interesting phenomenon but clinically seem to be of only weak prognostic value.

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: Emerging surgical methods are utilized to treat endometrial cancer. The study aimed to assess the efficacy and safety of four common surgical methods of hysterectomy.
Methods: We systematically searched the PubMed, Cochrane Library databases, Medline, EMBASE and Web of Science from their inception until April 30, 2024.
Objectives: Squamous cell carcinoma of the anal canal (SCCA) is a rare condition. Standard treatment includes chemoradiotherapy, with surgical treatment reserved for limited cases. In the future, the decrease in surgical frequency makes it more difficult to pathologically assess the depth of tumor invasion and lymph node status; therefore, those studies based on relatively recent surgical cases may offer valuable insights into diagnosing and treating SCCA.

Purpose: The thyroid gland is an organ at risk in breast cancer survivors who receive radiation therapy to the supraclavicular lymph nodes. We investigated the effect of radiation dose to the thyroid gland on the incidence of hypothyroidism in early-stage breast cancer patients treated with CT-guided radiation therapy.
Patients And Methods: We recruited women aged ≤75 years diagnosed with breast cancer from March 2016 through August 2017 at Odense University Hospital, Denmark.

Objective: To investigate the relationship of pretreatment of circulating tumor cells (CTCs) and cervical lymph node metastasis (LNM) (central LNM (CLNM) and lateral LNM (LLNM)) in papillary thyroid carcinoma (PTC) patients with ≤ 55 years old.
Methods: Clinicopathological data (CTCs level, Hashimoto's thyroiditis, thyroid function, multifocal, tumor size, invaded capsule, clinical stage, and LNM) of 588 PTC patients with ≤ 55 years old were retrospectively collected. The relationship of CLNM, LLNM and the clinical features of patients was analyzed.
