One of the known histological patterns of endometrioid carcinoma (EC) in uterine corpus cancer is MELF (microcystic, elongated, and fragmented). MELF is associated with lymphovascular invasion and lymph node metastasis. Besides MELF, it is also known that squamous differentiation (SD) often occurs in EC. SD is known to be no significant difference in the frequency of lymph node metastasis in EC. However, there have been no previous reports on the association between MELF and SD. In this research, we investigated the presence of SD in MELF using an antibody to CK5. We examined 28 cases of EC with MELF pattern, in which 15 cases showed SD. Moreover, the relation of lymph node metastasis to SD was examined. Lymph node dissection was performed in 27 out of 28 cases. Among them, 12 cases showed lymph node metastasis. The ratio of lymph node metastasis was significantly higher in EC with SD (64.3 %, 9 in 14 cases) than EC without SD (23.1 %, 3 in 13 cases). In this study, we first showed the association between SD and MELF and that MELF with SD is associated with a high ratio of lymph node metastasis. It is clinically relevant to recognize that MELF with SD is aggressive with a high ratio of lymph node metastasis.

More micrometastases, more recurrence? The role of qPCR of PSA mRNA in lymph nodes during prostatectomy.

Background And Objectives: Radical prostatectomy is a standard treatment for prostate cancer, yet about 30% of patients experience rising biochemical markers within a decade post-surgery. Pelvic lymph node sampling during prostatectomy assesses potential lymph node metastases, but standard histological assessments, which typically examine only 2-3 tissue sections, often miss occult metastases. This study assesses the effectiveness of qPCR in detecting PSA coding KLK3 mRNA for identifying lymph node metastases post-prostatectomy and explores the correlation between PSA-mRNA and biochemical recurrence.

Background And Purpose: It remains unclear whether the lymph-node ratio (LNR) is a relevant factor for the risk of recurrence following neoadjuvant chemotherapy (nCT) with docetaxel, cisplatin, and 5-fluorouracil (DCF), which is a new standard of care for locally advanced esophageal squamous cell carcinoma (ESCC) in Japan. This study aimed to evaluate the clinical utility of LNR as a risk factor for recurrence.
Materials And Methods: We retrospectively analyzed 75 patients who underwent nCT-DCF followed by curative surgery for resectable ESCC.

Background: The aims of this cohort study were to identify (1) the incidence and risk factors for axillary web syndrome (AWS) with shoulder movement limitation within 4 weeks after axillary lymph node dissection (ALND) for Asian women with breast cancer (BC), and (2) whether early intervention with physical therapy (PT) could improve AWS, and how many PT sessions would be needed.
Methods: A cohort study of patients with BC receiving ALND was performed at Changhua Christian Hospital, Taiwan, between January 2019 and December 2020. Those patients who were diagnosed with AWS with shoulder movement limitation were referred to receive PT twice weekly at the Department of Physical Medicine and Rehabilitation.

This study developed a prognostic model for patients with colon adenocarcinoma (COAD) based on glycosylation-associated genes. By analyzing TCGA-COAD data, 110 key genes were identified, and a prognostic model incorporating five glycosylation-related genes was constructed. The model exhibits good predictive performance and is significantly associated with clinical features such as age, N stage, M stage, and lymph node count.

Introduction: Stage IV non-small cell lung carcinoma (NSCLC) with oligometastases is potentially curable by radical treatment. This study aimed to evaluate the efficacy and safety of chemoradiotherapy (CRT) for thoracic disease, including the primary lesion and lymph node metastases, combined with local consolidative therapy (LCT) for oligometastases.
Methods: This was a multicenter Phase II trial for patients with Stage IV NSCLC with oligometastases for whom CRT for thoracic disease was feasible.
