Background: In early-stage endometrial cancer (EC), the treatment of aggressive histological subtypes (endometrioid carcinoma grade 3, serous carcinoma, clear-cell carcinoma, undifferentiated carcinoma, mixed carcinoma, and carcinosarcoma) is controversial. We aimed to investigate the treatment of patients with International Federation of Gynecology and Obstetrics (FIGO) stage IC and stage IIC EC according to the 2023 classification.

Methods: We retrospectively identified patients with FIGO 2023 stage IC, IIC-intermediate risk (IIC-I), and IIC-high risk (IIC-H) EC who underwent adjuvant therapy or observation after surgery at eight medical institutions from 2004 to 2023.

This study investigated whether pretreatment neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and prognostic nutritional index (PNI) are prognostic factors in patients with cervical cancer who undergo concurrent chemoradiotherapy (CCRT) and radiotherapy (RT). A total of 131 patients who underwent CCRT and RT for cervical cancer were retrospectively investigated and the correlations of NLR, PLR and PNI with clinical parameters and prognosis were assessed in CCRT and RT. The CCRT and RT groups had a median progression-free survival (PFS) of 41.

Inflammation and tumor immunology are associated with prognosis in a variety of cancers. The aim of the present retrospective study was to identify associations between the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), cancer antigen 125 (CA125) concentrations, tumor response, performance status (PS) and survival of patients that developed recurrent ovarian cancer subsequent to receiving chemotherapy. The NLR and PLR measured prior to fourth-line chemotherapy were significantly increased compared with those measured prior to second-line chemotherapy (P=0.

Collision tumors, which are characterized by the coexistence of two or more completely distinct and independent tumors in the uterine corpus, are very rare. A collision tumor is mainly composed of two distinct tumor types, epithelial and mesenchymal. To the best of our knowledge, there has only been a single case in which a choriocarcinoma with an endometrial carcinoma were coexistent but histologically distinct.

Pure ovarian choriocarcinoma is an extremely rare malignancy that can be gestational or non-gestational in origin. Silver-Russell syndrome (SRS) is a rare congenital developmental disorder characterized by pre- and postnatal growth failure, relative macrocephaly, a triangular face, hemihypotrophy, and fifth-finger clinodactyly. We report a rare case of pure ovarian choriocarcinoma occurring in a 19-year-old woman with SRS.

Cases of cardiac metastasis from uterine cervical carcinoma are rare. While they are occasionally found on autopsy, antemortem recognition is extremely rare. We confirmed a case of cardiac metastasis from cervical carcinoma antemortem, because we observed a decrease in platelet count during the course of treatment.

Article Synopsis
  • Struma ovarii is a rare type of ovarian tumor that resembles malignant ovarian carcinoma in ultrasound imaging, leading to more open surgeries than minimally invasive ones.
  • In a study of three premenopausal women (ages 31-50), struma ovarii was accurately diagnosed before surgery using various imaging techniques, including MRI, CT, PET-CT, and scintigraphy.
  • Laparoscopic surgery was successfully performed without tumor rupture, highlighting that advanced MRI techniques and careful surgical approach can improve preoperative diagnosis and treatment options for struma ovarii.

Purpose: The purpose of this study was to investigate the prognostic value of the minimum apparent diffusion coefficient (ADCmin) derived from diffusion-weighted MR imaging and of the maximum standardized uptake value (SUVmax) derived from PET/CT imaging of the primary tumour in patients with endometrial cancer.

Methods: SUVmax reflects the highest tumour metabolism rate and ADCmin reflects the highest cellularity, and both parameters have been used for tumour grading and prediction of prognosis. The correlations between prognosis and SUVmax and ADCmin of the primary tumour were determined in 131 patients with endometrial cancer.

We generated novel truncated insulin-like growth factor I receptors (IGF-IRs) designated as 126/STOP, 223/STOP and 325/STOP in order to establish shorter soluble IGF-IRs than previously reported 486/STOP without abrogating the same antitumor effects. Stable transfection of 223/STOP and 325/STOP, but not 126/STOP caused inhibition of anchorage-independent growth of CaOV-3 ovarian cancer cells in vitro. This antitumor effect was reproduced when we used recombinant proteins of these constructs, suggesting a bystander effect of these shorter truncated IGF-IRs.

Background: Although anthracyclines are considered as being among the most potent chemotherapeutic agents for endometrial carcinoma, the majority of institutions in Japan prefer a combination of paclitaxel and carboplatin (TC) for treating this disease. We retrospectively evaluated the efficacy and feasibility of combined paclitaxel, pirarubicin, and carboplatin (TPC) therapy for endometrial carcinoma.

Methods: Thirty-nine patients with high/intermediate postoperative recurrence risks or with advanced disease received combination chemotherapy consisting of paclitaxel (150 mg/m(2)), pirarubicin (35 mg/m(2)), and carboplatin [area under the concentration time curve (AUC = 4)] from 2001 to 2006 at Okayama University Hospital.
