Background: There is no article that studies whether the regional lymph node (RLN) status affects the prognosis of Merkel cell carcinoma (MCC).
Methods: The survival and disease data of MCC patients were obtained from the Surveillance, Epidemiological, and End Results (SEER) database. The overall survival (OS) and cause-specific survival (CSS) rates were endpoints.
Results: A total of 1822 patients were included, with a mean age of 72.5 years. The number of RLN-positive patients was 862 (47.3%), and the number of RLN-negative patients was 960 (52.7%). The regression analysis showed that primary site, sex, and tumor size were statistically significant and independent predictors of RLN status. The five-year OS and CSS of RLN-negative patients were 71.4% and 92.3%, respectively, which were much higher than those of RLN-positive patients (37.5% and 65.8%, respectively) (P <0.001). In univariate survival analysis, positive RLN significantly predicted deterioration of OS and MSS (P <0.001). In multivariate analysis, RLN status had no statistically significant effect on patient prognosis.
Conclusion: The prognosis of patients with RLN metastasis is worse than that of patients without RLN metastasis, but RLN status is not an independent predictor of the prognosis of patients with MCC.

Therapeutic Management in Elderly Male Breast Cancer Patients: A Scoping Review.
Curr Oncol Rep
January 2025
Radiation Oncology Department, General Regional Hospital "F.Miulli", Acquaviva Delle Fonti, Bari, Italy.
Purpose Of Review: Male breast cancer (MBC) is a rare entity which often arises in elderly people. Aim of this review is to evaluate the principal issues related to MBC in elderly, because the therapeutic management of disease is not only related to the biological behavior of the tumor, but also to the comorbidities and frailty of older population. A scoping literature review was performed on Pubmed and Cochrane Database using the following keywords: therapeutic management/ male/ breast cancer/ elderly patients.

Unlabelled: Endoscopic submucosal dissection (ESD) is the technique of choice in the management of early gastric cancer. Recently, it is also considered as an absolute indication in selected cases of early undifferentiated gastric cancer (U-EGC).
Objectives: In the present study, the first documented cases of ESD in patients with U-EGC are presented and analyzed.

January 2025
Department of Pediatrics, Sichuan Provincial Women's and Children's Hospital/Affiliated Women's and Children's Hospital of Chengdu Medical College, Chengdu 610045, China.
Objectives: To explore the predictive factors for non-response to intravenous immunoglobulin (IVIG) in children with Kawasaki disease (KD) and to establish an IVIG non-response prediction scoring model for the Sichuan region.
Methods: A retrospective study was conducted by collecting clinical data from children with KD admitted to four tertiary hospitals in Sichuan Province between 2019 and 2023. Among them, 940 children responded to IVIG, while 74 children did not respond.
Comparison of Sublobar Resection and Proton Therapy for Early-Stage Non-small Cell Lung Cancer.
Clin Lung Cancer
December 2024
Department of Thoracic Surgery, Nagoya City University West Medical Center, Nagoya, Japan.
Background: For early-stage lung cancer, sublobar resection (SLR) is an alternative to lobectomy, which is the standard treatment. Recently, proton therapy (PT) is being increasingly used, even in patients with operable lung cancer, as an attractive alternative to conventional radiation therapy. Thus, we performed propensity score matching (PSM) to compare the outcomes of SLR and PT in patients with early-stage non-small cell lung cancer (NSCLC).
