Abstract
Patient-derived xenograft (PDX) models retain the characteristics of tumors and are useful tools for personalized therapy and translational research. In this study, we aimed to establish PDX models for uterine corpus malignancies (UC-PDX) and analyze their similarities. Tissue fragments obtained from 92 patients with uterine corpus malignancies were transplanted subcutaneously into immunodeficient mice. Histological and immunohistochemical analyses were performed to compare tumors of patients with PDX tumors. DNA and RNA sequencing were performed to validate the genetic profile. Furthermore, the RNA in extracellular vesicles (EVs) extracted from primary and PDX tumors was analyzed. Among the 92 cases, 52 UC-PDX models were established, with a success rate of 56.5%. The success rate depended on tumor histology and staging. The pathological and immunohistochemical features of primary and PDX tumors were similar. DNA sequencing revealed similarities in gene mutations between the primary and PDX tumors. RNA sequencing showed similarities in gene expressions between primary and PDX tumors. Furthermore, the RNA profiles of the EVs obtained from primary and PDX tumors were similar. As UC-PDX retained the pathological and immunohistochemical features and gene profiles of primary tumors, they may provide a platform for developing personalized medicine and translational research.

Abstract
Sentinel node biopsy (SNB) is performed worldwide in patients with endometrial cancer (EC). The aim of this study was to evaluate and compare the occurrence rate of lymphatic complications between SNB and pelvic lymphadenectomy (LND) for EC. The medical records of women who underwent SNB or pelvic LND for EC between September 2012 and April 2022 were assessed. A total of 388 patients were enrolled in the current study. Among them, 201 patients underwent SNB and 187 patients underwent pelvic LND. The occurrence rates of lower-extremity lymphedema (LEL) and pelvic lymphocele (PL) were compared between the patients who underwent SNB and those who underwent pelvic LND. The SNB group had a significantly lower occurrence rate of lower-extremity LEL than the pelvic LND group (2.0% vs. 21.3%, p < 0.01). There were no patients who had PL in the SNB group; however, 4 (2.1%) patients in the pelvic LND group had PL. The occurrence rates of lower-extremity LEL and PL were significantly lower in patients who underwent SNB than those who underwent pelvic LND. SNB for EC has a lower risk of lymphatic complications compared to systemic LND.

Abstract
Adnexal torsion frequently causes acute pelvic pain in women. Ovarian tumour torsion is common; twisting and torsion of a fallopian tube are rare. This report presents a rare case of fallopian tubal torsion requiring the management of a large hydrosalpinx with laparoscopic surgery. A 48-year-old woman reported with acute abdominal pain and lower abdomen tenderness. Transvaginal ultrasonography and Magnetic Resonance Imaging (MRI) showed a cystic mass on the anterior uterine surface. Emergency surgery was performed for a suspected torsion of the left ovarian cyst. In the abdominal cavity, the left fallopian tube was enlarged (neonatal head size), dark purple coloured, and exhibited a 180° torsion; the left ovary was normal. Laparoscopic left salpingectomy was performed and the postoperative course was uneventful. Surgical pathology revealed hydrosalpinx with torsion. As diagnosing isolated fallopian tube torsion before surgery is difficult, laparoscopic surgery is useful in diagnosing and treating isolated tubal torsion.

Abstract
Pyometra usually develops in elderly women, and it can be caused by various etiologies. We describe a rare case of pyometra with a colouterine fistula due to rectal cancer presenting as acute abdomen. A 67-year-old woman with purulent vaginal discharge and abdominal distension was referred to our hospital for suspected pyometra. Because the vaginal echogram showed pyometra at her initial medical examination, drainage was performed. Her symptoms subsequently disappeared temporarily, but 4 months later, she developed acute abdomen. The computed tomography scan showed a pelvic mass with expansion of the intestine. The patient underwent en bloc resection of the mass. Histopathologic analysis of the tumor showed rectal cancer with invasion of the uterus and ileum, and a colouterine fistula. Although pyometra due to a colouterine fistula is a very rare condition, the incidence of associated malignancy is considerable. Physicians should be aware of this potential presentation of colorectal cancer.
