Objective: To identify a relatively high-risk population in postoperative intermediate-risk cervical cancer and evaluate the effect of platinum-based adjuvant chemotherapy (CT). Methods: We retrospectively reviewed the medical records of patients with stage IA2-IIA cervical cancer who had been treated with radical hysterectomy and pelvic lymphadenectomy and classified as the intermediate-risk group for recurrence by postoperative pathological examination from January 2007 to December 2018 at 3 medical centers in Japan. First, patients with intermediate-risk were stratified by histological type and the number of intermediaterisk factors (IRF; large tumor diameter, lymph vascular space invasion, and deep cervical stromal invasion) and then divided into 2 groups: high and low-risk population (estimated 5-year recurrence-free survival [RFS] rate with no further therapy [NFT] <90% and ≥90%, respectively). Second, the efficacy of CT for the high-risk population was evaluated by comparing RFS and overall survival (OS) between the patients receiving CT and those with NFT. Results: In total, 133 patients were included in the analysis. Among patients with squamous cell carcinoma (SCC) with all IRF or those with non-SCC with 2 to 3 IRF, the 5-year estimated RFS was <90% when treated with NFT. In this population, adjuvant CT was significantly superior to NFT regarding RFS (log-rank, p=0.014), although there was no statistical difference in OS. Conclusion Patients with SCC with all 3 IRFs and those with non-SCC with 2 to 3 IRFs were at high risk for recurrence. Adjuvant CT is a valid treatment option for these populations.

Objective: In Japan, perioperative prophylaxis of pulmonary embolism (PE) in gynecologic cancer patients with preoperative asymptomatic venous thromboembolism (VTE) has not been well established yet. The GOTIC-VTE trial was a prospective, multi-center, single-arm clinical trial to investigate the prevention of postoperative symptomatic PE onset by seamless anticoagulant therapy from the preoperative period to 4 weeks after surgery instead of using intermittent pneumatic compression. Methods: Anticoagulant therapy was started immediately after asymptomatic VTE diagnosis and stopped preoperatively according to the rules of each institution. Unfractionated heparin administration was resumed within 12 hours postoperatively, and this was followed by the switch to low-molecular-weight heparin and subsequently, edoxaban; this cycle was continued for 28 days. Primary outcome was the occurrence of symptomatic PE in 28 days postoperatively. Secondary outcomes were the incidence of VTE-related events in 28 days and 6 months postoperatively and protocol-related adverse events. Results: Between February 2018 and September 2020, 99 patients were enrolled; of these, 82patients were assessed as the full analysis set, including 58 for ovarian cancer, fallopian tube, or peritoneal cancer; 21 for endometrial cancer; and 3 for cervical cancer. No symptomatic PE was observed within 28 days postoperatively; two patients had bleeding events (major bleeding and clinically relevant nonmajor bleeding) and three had grade 3 adverse events (increased alanine transaminase, aspartate aminotransferase, or gamma-glutamyl transferase). Conclusion The multifaceted perioperative management for gynecologic malignancies with asymptomatic VTE effectively prevented postoperative symptomatic PE.Trial Registration: JRCT Identifier: jRCTs031180124

Background: No consensus exists regarding which anthropometric measurements are related to bone mineral density (BMD), and this relationship may vary according to sex and age. A large Japanese cohort was analyzed to provide an understanding of the relationship between BMD and anthropometry while adjusting for known confounding factors. Methods: Our cohort included 10,827 participants who underwent multiple medical checkups including distal forearm BMD scans. Participants were stratified into four groups according to age (≥50 years or <50 years) and sex. The BMD values were adjusted for confounding factors, after which single and partial correlation analyses were performed. The prevalence of osteopenia was plotted for each weight index (weight or body mass index [BMI]) class. Results: Cross-sectional studies revealed that weight was more favorably correlated than BMI in the older group (R=0.278 and 0.212 in men and R=0.304 and 0.220 in women, respectively), whereas weight and BMI were weakly correlated in the younger age groups. The prevalence of osteopenia exhibited a negative linear relationship with weight among older women ≥50 years of age, and an accelerated increase was observed with decreasing weight in older men weighing <50 kg and younger women weighing <60 kg. When weight was replaced with BMI, the prevalence was low in most subgroups classified by weight. Conclusions Weight, rather than BMI, was the most important indicator of osteopenia but it might not be predictive of future bone loss.

We report a case of a 72-year-old woman with a tumor arising from a colostomy site that had been created 25 years earlier when rectal amputation was performed for perforated sigmoid cancer. She was referred to our hospital due to complaints of pain from the colostomy. The diagnosis was carcinoma arising at the colostomy site with lymph node metastasis. Laparoscopic surgery was performed by attaching an Applied Alexis® wound retractor to the incision site of the colostomy. Lymph node dissection was performed and the left hemicolon was resected. Carcinoma arising from a colostomy site is rare. Laparoscopic surgery was considered to be a useful procedure because it allows for lymph node dissection and intestinal mobilization with minimal invasiveness.

Objective: The initial and operational costs of telemedicine are major barriers to its adoption. We aimed to investigate and identify the barriers to adopting a telemedicine system in a Japanese rural general hospital without incurring setup and operational costs.Materials and Methods: Our study was conducted between May and August 2018, and included six general practitioners working at a rural general hospital. We extracted data collected from messages (date and time, sender and recipient, and counts and contents of messages) and conducted semi-structured interviews, which were then analyzed using quantitative and qualitative methods.Results: We quantitatively analyzed the total counted of the 179 messages. The total counts recorded for each physician were 56 (A), 20 (B), 3 (C), 74 (D), 5 (E), and 21 (F). The mean monthly counts were 2.17 (May), 8.50 (June), 11.50 (July), and 7.67 (August). Interview data from the six physicians yielded 13 codes that included various points of dissatisfaction acting as barriers to using our system, which we grouped into mental and physical barriers. Mental barriers included suspicion of carrying, feelings of isolation, and loss, whereas physical barriers included portability, user authentication, internet speed, group chat system, notice, search image, typing, chat system, print facility, and limited function.Conclusion: The representative barriers to introducing a telemedicine system at a rural general hospital in Japan without initial and running costs could be classified as feelings of isolation and suspicion of carrying (mental barriers); and notice, portability, and user authentication (physical barriers). Continued investigation in this area is warranted, and solutions to these barriers could improve the shortage of medical staff in the context of declining birth rates and aging populations in Japan.

Methods: We examined 242 patients (age >60 years) who underwent surgery for thoracic to lumbar spine fractures from 2010 to 2020. Subsequently, the maxVB was classified into three groups: maxVB (0), maxVB (2–8), and maxVB (9–18), and parameters, including fracture morphology (new Association of Osteosynthesis classification), fracture level, and neurological deficits were compared. In a sub-analysis, 146 patients with thoracolumbar spine fractures were classified into the three aforementioned groups based on the maxVB and compared to determine the optimal operative technique and evaluate surgical outcomes. Results: Regarding the fracture morphology, the maxVB (0) group had more A3 and A4 fractures, whereas the maxVB (2–8) group had less A4 and more B1 and B2 fractures. The maxVB (9–18) group exhibited an increased frequency of B3 and C fractures. Regarding the fracture level, the maxVB (0) group tended to have more fractures in the thoracolumbar transition region. Furthermore, the maxVB (2–8) group had a higher fracture frequency in the lumbar spine area, whereas the maxVB (9–18) group had a higher fracture frequency in the thoracic spine area than the maxVB (0) group. The maxVB (9–18) group had fewer preoperative neurological deficits but a higher reoperation rate and postoperative mortality than the other groups. Conclusions The maxVB was identified as a factor influencing fracture level, fracture type, and preoperative neurological deficits. Thus, understanding the maxVB could help elucidate fracture mechanics and assist in perioperative patient management.
