: The usefulness of bevacizumab (BEV) as first-line chemotherapy for advanced ovarian clear cell carcinoma (CCC) was retrospectively evaluated at Tohoku Gynecologic Cancer Unit institutions. : A total of 81 patients (52 patients without BEV and 29 with BEV) with advanced ovarian CCC who received initial platinum-based chemotherapy were enrolled. We selected 26 patients each without and with BEV according to propensity score matching methods, and compared the platinum-resistant recurrence rate, response rate, progression-free survival (PFS), overall survival (OS), and adverse events between the two groups.

Aim: We aimed to assess the amniotic fluid glucose concentration cut-off as an indicator of fetal chromosomal abnormalities, such as trisomy 13, 18, and 21.
Methods: This prospective observational study included pregnant females who underwent amniocentesis. Participants were divided into two groups on the border of 22 weeks of gestational age (<22 and ≥22-week groups).
During human embryonic development, early cleavage-stage embryos are more susceptible to errors. Studies have shown that many problems occur during the first mitosis, such as direct cleavage, chromosome segregation errors, and multinucleation. However, the mechanisms whereby these errors occur during the first mitosis in human embryos remain unknown.

Working women are considered to have the greatest need for preconception care, as increasingly they marry and have children later in life. This study aimed to assess the feasibility and effectiveness of preconception check-ups in the workplace.

Understanding its pathophysiology is often difficult, together with its treatment. Here, we present a case of CUP with abdominal lymph node enlargement and elevated carbohydrate antigen 125 levels.

Visualization of the intracellular organelles and cytoskeleton allows elucidation of the development of early mammalian embryos. The behavior of the DNA and cytoskeleton in early mammalian embryos has conventionally been observed by injecting target molecule mRNAs, incorporating a fluorescent substance-expressing gene, into embryos.

Aims: This study aimed to assess the IME factors and evaluate their prognostic values.
Methods And Results: We assessed CD8 tumor-infiltrating lymphocyte (TIL) density, forkhead box protein P3 (Foxp3 ) TIL density, and programmed death receptor ligand-1 (PD-L1) tumor proportion score (TPS) using a machine-learning algorithm in whole-slide imaging (WSI).
Research Question: How does the cost-related oocyte cryopreservation (OoC) vary by the facility in Japan, and what data is provided on the websites about OoC procedures?
Design: Website survey. The websites of all 621 facilities that provide assistive reproductive technology registered in Japan were surveyed in 2021. Data included the rates of explicit statements regarding the provision of OoC for only medical reasons (medical only group) or non-medical reasons (non-medical group).
Background: In the current tumor-node-metastasis (TNM) classification, the clinical T descriptor is defined by solid size (SS) on a computed tomography (CT) slice and the pathological one is done by invasive size (IS) in microscopic evaluations. We sometimes experience discrepancies in diagnosis of both descriptors. A volume analyzing application enables semi-automatic measurement of three-dimensional (3D) parameters in cases where there are discrepancies in diagnosing tumors' solid size and IS.

Objective: Positive pleural lavage cytology (PLC +) is a poor prognostic factor for non-small cell lung cancer (NSCLC). However, data on the impact of intraoperative rapid diagnosis of PLC (rPLC) are lacking. Therefore, we evaluated the efficacy of rPLC before resection during surgery.

Although abnormalities in glucose metabolism normally resolve rapidly after delivery, women with GDM have a higher lifetime risk of developing diabetes mellitus than those without GDM; thus, postpartum healthcare is essential. Of all GDM patients, 5%-10% test positive for diabetes-related autoantibodies, which increase the risk of developing type 1 diabetes mellitus (T1DM).

In June 2020, we recruited students aged between 18 and 35 years from four universities in Japan. Among the 357 enrollees (female, 53%), 178 and 179 participants were randomized into the LINE and Mail groups, respectively.

Applying digital tissue image analysis to whole-slide imaging may enhance the accuracy and reproducibility of pathological assessment. This study aimed to evaluate the prognostic value of tumour components of lung adenocarcinoma by measuring the dimensions of the tumour consisting elements separately, using a machine learning algorithm.

This study aimed to identify the association between the quantitative severity of emphysema detected by the low-attenuation area on computed tomography and the prognostic outcome of early non-small-cell lung cancer.
Methods: A consecutive series of 1062 patients who underwent lobectomy for clinical stage I and II non-small-cell lung cancer were enrolled in this study.
Background: Outcomes with and without bevacizumab as first-line chemotherapy in Japanese-only ovarian cancer patients have not been reported. In this study, we report a retrospective study conducted at the Tohoku Gynecologic Cancer Unit.
Patients And Methods: The study included 453 patients with stage III/IV ovarian, fallopian tube, and primary peritoneal cancer who received first-line platinum-based chemotherapy.
Purpose: Several studies reported the possibility of predicting genetic abnormalities in non-small-cell lung cancer by deep learning (DL). However, there are no data of predicting gene rearrangement () using DL. We evaluated the predictability using the DL platform.

At the time of this survey, Japan provided partial reimbursement for ART treatment only for those in low- or middle-income classes due to limited governmental budgets. However, the optimal level of financial support by income class remains unclear.

Despite this being offered in several facilities in urban areas, NIPT remains to be scarcely unavailable in rural areas. Moreover, there is lacking information with regard to how pregnant women in rural areas perceive NIPT.

Methods: Study I: HOF was collected laparoscopically from patients (= 28) with normal pelvic findings. According to HOF analysis results, the new medium "HiGROW OVIT" (OVIT) was designed.
A 28-year-old woman exhibited a spiking fever, arthritis, and liver disfunction when she was 22 weeks pregnant. She was diagnosed with adult-onset Still's disease (AOSD). As her condition was resistant to corticosteroid therapy, tocilizumab (TCZ) was selected.

A global navigation satellite system (GNSS) buoy system for early tsunami warnings has been developed for more than 20 years. The first GNSS buoy system using a real-time kinematic algorithm (RTK) was implemented in the Nationwide Ocean Wave information network for Ports and HArbourS (NOWPHAS) wave monitoring system in Japan in 2008. The records of NOWPHAS were used to update the tsunami alert by the Japan Meteorological Agency (JMA), owing to the tsunami generated by the 2011 Tohoku-oki earthquake (Mw9.
