(Summary) Human papillomavirus vaccination is not widespread in Japan, and the low screening rates result in many cases of locally advanced cervical cancer. We investigated the prognostic significance of sarcopenia in patients with cervical cancer to guide healthcare policies to improve treatment outcomes. This retrospective study included 83 patients with cervical cancer without distant metastasis who underwent primary concurrent chemoradiotherapy between 2013 and 2018. We analyzed the indicators of physical condition and muscle quantity using the SYNAPSE VINCENT software. Muscle mass and the relationship between treatment toxicity and prognosis were evaluated. The patients' median age was 60 (range 33-80) years. Cancer stage distribution was as follows: cT2b or higher, 84.3%; N1, 65.1%; and MA, 27.7%. The overall sarcopenia (skeletal muscle index [SMI] < 38.5) rate was 30.1%, and the rate was 33.9 and 22.2% in patients aged < 64 and ≥ 65 years, respectively. No correlation was observed between clinical stage and musculoskeletal indices. Treatment resulted in decreased body weight and SMI; after treatment, the sarcopenia rate increased to 37.3%. A higher intramuscular adipose tissue content (IMAC) reduced the number of chemotherapy cycles needed. Treatment-associated SMI decreases of ≥ 7% indicated poor prognosis, with significant differences in progression-free survival and overall survival (p = 0.013 and p = 0.012, respectively). Patients who were very lean (body mass index < 18.5 kg/m) before treatment had a poor prognosis (p = 0.016 and p < 0.001). Our findings emphasize the importance of assessing original nutritional status and maintaining muscle mass and quality during the treatment of patients with cervical cancer.

(Summary) Although animal models of PCOS have been used in many studies, none of them can reproduce both the reproductive and metabolic phenotypes of PCOS. In addition, behavioral parameters have not been evaluated in PCOS animal models. We tried to produce an improved rat model of PCOS, and the reproductive, metabolic, and behavioral phenotypes of the model rats were evaluated. Female rats were implanted with silicon tubes containing oil-dissolved dihydrotestosterone (Oil-DHT) as a new PCOS model. Their phenotypes were compared with those of conventional PCOS model rats (DHT), into which tubes containing crystalline DHT were implanted, and non-DHT-treated rats (control). Both the Oil-DHT and DHT rats showed greater body weight gain, food intake, and fat depot weight than the control rats. Furthermore, these groups showed fewer estrous stages and increased numbers of cystic follicles. The DHT rats exhibited lower ovarian and uterine weights than the control rats, whereas no such changes were observed in the Oil-DHT rats. The Oil-DHT and DHT rats showed less locomotor activity in the light phase than the control rats. Our proposed PCOS model reproduced both the reproductive and metabolic phenotypes of PCOS and may have potential for PCOS research.

(Summary) Resveratrol, a natural product and peroxisome proliferator-activated receptor (PPAR) agonist, has been reported to exert anti-cancer effects in several tumor models. A previous study by our group reported that prostaglandin J2, a PPARγ ligand, inhibited cell proliferation in a uterine sarcoma cell line. The aim of the present study was to investigate the role of the Wnt signaling pathway in resveratrol-induced apoptosis and inhibition of cell proliferation in the MES-SA human uterine sarcoma cell line. A WST-1 assay demonstrated that resveratrol inhibited cell proliferation in the MES-SA cell line, and flow cytometry revealed that the number of apoptotic cells increased in a resveratrol dose-dependent manner. The mechanisms underlying these effects of resveratrol were speculated to involve the expression of β-catenin and its target gene, c-myc, which were examined using western blot analysis. The results revealed a dose-dependent downregulation of this β-catenin and c-myc. This effect was blunted by a pharmacological inhibitor of glycogen synthase kinase 3β. Therefore, it is likely that resveratrol inhibited the cell proliferation and increased the number of apoptotic cells, at least partially, via the Wnt signaling pathway. The present results suggest that resveratrol is a potential candidate for the treatment of uterine sarcoma.

(Summary) In recent years, the effects of androgens on metabolic and body weight regulation systems and their underlying mechanisms have been gradually revealed in females. In women and experimental animals of reproductive age, androgen excess can adversely affect metabolic functioning, appetite, and body weight regulation. In addition, excess androgens can increase the risk of metabolic disorders, such as obesity, insulin resistance, and diabetes. These unfavorable effects of androgens are induced by alterations in the actions of hypothalamic appetite-regulatory factors, reductions in energy expenditure, insulin resistance in skeletal muscle, and β-cell dysfunction. Interestingly, these unfavorable effects of androgens on metabolic and body-weight regulation systems are neither observed nor evident in ovariectomized animals and post-menopausal women, indicating that the adverse effects of androgens might be dependent on the estrogen milieu. Recent findings may provide novel sex- and age-specific strategies for treating metabolic diseases.

(Summary) <p>MPA therapy is widely administered to patients with early-stage endometrial cancer and atypical endometrial hyperplasia (AEH) who desire a fertility-preserving treatment modality. We examined the relationship between MMR protein expression and the effects of MPA therapy, risk of relapse, prognosis, and familial history in 21 patients. We observed MMR deficiency in 7 patients (MLH1: 4, PMS2: 5, MSH2: 2, and MSH6: 2). All patients with lymph node metastasis or who died had MLH1 deficiency. In 13 of 21 patients, we performed MPA therapy for fertility preservation and confirmed MMR deficiency in 2. After the initial treatment, ovarian cancer developed in 2 patients, one of whom had Peutz-Jeghers syndrome. Due to the small sample size of this study, we found no significant association between MMR deficiency and the effects of MPA therapy or the risk of relapse. Many young patients with endometrial tumors may have inherited diseases, although not necessarily with MMR deficiency. Therefore, clinical assessment considering their past history and family history should be performed prior to each treatment. Our findings will serve as a catalyst for future studies with larger sample sizes.</p> (Keyword) endometrial cancer / mismatch repair deficiency / hereditary tumor (Link to Publication Site) ● Publication site (DOI): 10.18976/jsht.20.3_146 (Link to Search Site for Scientific Articles) ● CiNii @ National Institute of Informatics (CRID): 1390286981364673792 ● Search Scopus @ Elsevier (DOI): 10.18976/jsht.20.3_146 (DOI: 10.18976/jsht.20.3_146, CiNii: 1390286981364673792)
