Background And Objectives: Despite the availability of initial data on sentinel lymph node biopsy (SLNB) in OSCC, its value in clinical practice remains unclear. The aim of this study is to evaluate the feasibility and potential of SLNB as a reliable staging procedure in early stage SCC of the lips and the oral mucosa.
Methods: From 2001 to 2004, 40 patients with early stage SCC of the lips and oral cavity were enrolled. The main inclusion criteria were: cN0 category by MRI and ultrasound, tumor category T1-T2, for certain sites also T3. Patients with positive SLN underwent MRND and/or radiation. Patients with negative SLN were monitored monthly.
Results: In eight patients, the SLN were positive. Two patients with negative SLN subsequently developed nodal disease (5% false negatives). Twenty-one patients have a follow-up longer than 24 months. Five patients died (one from nodal disease, one from local recurrence, and three from unrelated causes). One patient developed a second primary tumor, the remaining patients are free of disease.
Conclusions: SLNB may contribute to more targeted lymph node dissection strategies. Further studies will have to ensure the safety of this procedure in comparison to selective neck dissection.

Cisplatin, a platinum-based chemotherapeutic agent, can be used to treat cervical cancer (CC), but cisplatin resistance is increased during the cisplatin treatment. Long non-coding RNA PGM5-AS1 reportedly participates in CC tumorigenesis; however, its role in CC patients with cisplatin resistance has not been revealed. The present aimed to examine the role of PGM5-AS1 in modulating cisplatin resistance in CC.

This study aimed to investigate the correlation between baseline MRI features and baseline carcinoembryonic antigen (CEA) expression status in rectal cancer patients. A training cohort of 168 rectal cancer patients from Center 1 and an external validation cohort of 75 rectal cancer patients from Center 2 were collected. A nomogram was constructed based on the training cohort and validated using the external validation cohort to predict high baseline CEA expression in rectal cancer patients.

PrPc is expressed in various tumors and is associated with cancer progression, but previous studies have shown conflicting results regarding its relationship with patient prognosis-potentially due to differences in the antibodies used. This study aimed to clarify the relationship between PrPc expression and primary esophageal squamous cell carcinoma (ESCC) and primary hepatocellular carcinoma (HCC) using a novel anti-PrPc antibody, 4AA-m, noted for its high specificity and sensitivity. We used flow cytometry to detect PrPc expression in ESCC and HCC cell lines.

Chronic lymphocytic leukemia (CLL) is prevalent in adults and is characterized by the accumulation of mature B cells in the blood, bone marrow, lymph nodes, and spleens. Recent progress in therapy and the introduction of targeted treatments [inhibitors of Bruton's tyrosine kinase (BTKi) or inhibitor of anti-apoptotic B-cell lymphoma-2 (Bcl-2i) protein (venetoclax)] in place of chemoimmunotherapy have significantly improved the outcomes of patients with CLL. These advancements have shifted the importance of traditional predictive markers, leading to a greater focus on resistance genes and reducing the significance of mutations, such as TP53 and del(17p).
