Objective: Given the paucity of data regarding the patterns of metastasis from ovarian sex cord-stromal tumors (SCSTs), we sought to determine the risk of lymph node metastasis in patients with SCSTs.
Methods: A retrospective chart review was performed after clinical and pathology databases were queried for ovarian SCST patients who were treated at our institution between 1985 and 2005.
Results: We identified 262 patients with pathology-confirmed ovarian SCSTs; 5 had additional non-stromal histology and were excluded, leaving 257 evaluable patients. Of these patients, 178 had adult granulosa cell tumors, 27 had juvenile granulosa cell tumors, 31 had Sertoli-Leydig cell tumors, 6 had sex cord tumors with annular tubules, 13 had mixed SCSTs, and 2 had SCSTs not otherwise specified. Our evaluation showed that 111 patients underwent a complete or partial staging procedure; 75 had stage I disease, 11 had stage II disease, and 25 had stage III disease. Fifty-eight of these 111 patients (52%) had lymph nodes removed as part of the staging procedure. Of the 58 patients who had lymph nodes sampled during the primary surgery, none had positive nodes. Of 117 patients whose disease eventually recurred, 6 patients (5.1%) had nodal metastases at the time of recurrence. Three of these patients had negative lymph nodes at initial staging.
Conclusions: Lymph node metastasis in ovarian SCSTs is rare. These findings suggest that lymphadenectomy may be omitted when staging patients with ovarian SCSTs.

Myelodysplastic Neoplasm (MDS) is a cancer associated with aging, often leading to acute myeloid leukemia (AML). One of its hallmarks is hypermethylation, particularly in genes responsible for DNA repair. This study aimed to evaluate the methylation and mutation status of DNA repair genes (single-strand - XPA, XPC, XPG, CSA, CSB and double-strand - ATM, BRCA1, BRCA2, LIG4, RAD51) in MDS across three patient cohorts (Cohort A-56, Cohort B-100, Cohort C-76), using methods like pyrosequencing, real-time PCR, immunohistochemistry, and mutation screening.

The incidence of keratinocyte carcinoma (KC) is rising globally, significantly burdening healthcare resources. Treatment options include medical treatment, non-invasive procedures, and surgery, each associated with their distinct benefits and risks. With advanced treatment, the procedures become increasingly invasive for the patients and expensive for the society.

Purpose: To develop and validate an MRI-based model for predicting postoperative early (≤2 years) recurrence-free survival (RFS) in patients receiving upfront surgical resection (SR) for beyond Milan hepatocellular carcinoma (HCC) and to assess the model's performance in separate patients receiving neoadjuvant therapy for similar-stage tumors.
Method: This single-center retrospective study included consecutive patients with resectable BCLC A/B beyond Milan HCC undergoing upfront SR or neoadjuvant therapy. All images were independently evaluated by three blinded radiologists.
Background: Coronary heart disease (CHD) and depression frequently co-occur, significantly impacting patient outcomes. However, comprehensive health status assessment tools for this complex population are lacking. This study aimed to develop and validate an explainable machine learning model to evaluate overall health status in patients with comorbid CHD and depression.

Objective: Pulmonary pleomorphic carcinoma is a relatively rare and aggressive subtype of non-small cell lung cancer (NSCLC), with a poor prognosis and early recurrence, and is resistant to conventional therapies. This study investigated the efficacy of immune checkpoint inhibitors (ICIs) in improving the survival outcomes of patients with pulmonary pleomorphic carcinoma with postoperative recurrence.
Methods: We conducted a retrospective analysis of 71 patients with pulmonary pleomorphic carcinoma who underwent pulmonary resection at Tokyo Medical University Hospital between 2008 and 2022.
