Objective:
This study aimed to determine whether the number of resected pelvic lymph nodes (PLNs) affects the prognosis of endometrial cancer (EC) patients at post-operative risk of recurrence.
Methods:
JGOG2043 was a randomized controlled trial to assess the efficacy of three chemotherapeutic regimens as adjuvant therapy in EC patients with post-operative recurrent risk. A retrospective analysis was conducted on 250 patients who underwent pelvic lymphadenectomy alone in JGOG2043. The number of resected and positive nodes and other clinicopathologic risk factors for survival were retrieved.
Results:
There were 83 patients in the group with less than 20 PLNs removed (group A), while 167 patients had 20 or more PLNs removed (group B). There was no significant difference in patients’ backgrounds between the two groups, and the rate of lymph node metastasis was not significantly different. There was a trend toward fewer pelvic recurrences in group B compared with group A (3.5% vs. 9.6%; p=0.050). Although Kaplan-Meier analysis showed no statistically significant difference in survival rates between the two groups (5-year overall survival [OS]=90.3% vs. 84.3%; p=0.199), multivariate analysis revealed that resection of 20 or more nodes is one of the independent prognostic factors (hazard ratio=0.49; 95% confidence interval=0.24–0.99; p=0.048), as well as surgical stage, high-risk histology, and advanced age for OS.
Conclusion
Resection of 20 or more PLNs was associated with improved pelvic control and better survival outcomes in EC patients at risk of recurrence who underwent pelvic lymphadenectomy alone and were treated with adjuvant chemotherapy.

A 78-year-old man presented with back pain 20 years after aortic root replacement using a homograft and was admitted with a diagnosis of pyogenic spondylitis. The patient had a history of prosthetic valve infective endocarditis (PVE) 9 months after aortic valve replacement (AVR) at 57 years of age at another hospital, and had undergone aortic root replacement using a homograft. Streptococcus anginosus was detected in blood culture, and antibiotic therapy was commenced according to the treatment of PVE. During the course of the treatment, the diagnosis of PVE was confirmed due to worsening aortic regurgitation (AR) and a finding of suspected vegetation attachment to the right coronary cusp. Since there were no embolic symptoms or heart failure, antibiotic therapy was preceded by surgery on the 33rd day. Intraoperatively, the homograft showed a highly calcified sinus of Valsalva and each valve leaflet was very fragile. The aortic valve had a vegetation adherent to the tip of the right coronary leaflet, but the infection was localized and did not extend to the annulus. Although aortic root replacement had been considered, the patient was elderly and had impaired activities of daily living, so AVR was performed in order to reduce the invasiveness of the procedure. The annulus was so hard that the needle could not be passed through. It was possible to thread the annulus by inserting the needle through the autologous tissue below the suture line on the proximal side of the homograft at the previous surgery. A bovine pericardial patch was used to close the aortotomy line of sclerotic homograft. There was no recurrence of infection, and the patient was transferred to the hospital for rehabilitation on postoperative day 37. The optimal surgical technique should be considered according to the degree of calcification and the patient's background in each case, as grafts are often highly calcified in cases of reoperation after homograft replacement.

People with high health knowledge tend to use information and communication technology (ICT) to obtain, maintain, and promote information necessary for health management. Therefore, experts hypothesize that improving health knowledge will increase the use of online medication guidance via ICT. In this study, we investigated the relationship between health knowledge and willingness to use online medication guidance among Iwaki Health Promotion Project health checkup subjects. The 736 examinees participating in this project in 2022 were surveyed on age, gender, number of people living with them, whether they exercise, drink alcohol, or smoke, whether they use smartphones, whether they use medication registers, their health knowledge score, and whether they take any medications. The presence/absence of desire for online medication guidance (1/0) was used as the objective variable to identify influencing factors. Univariate and multivariate analyses showed that independence was found for four factors: age (OR: 0.975, P<0.001), gender (male) (OR: 1.914, P<0.001), smartphone use (OR: 2.156, P=0.004) and health knowledge score (OR: 1.405, P<0.001). This study found that health knowledge plays a role in the intention to use online medication guidance. In order to improve health knowledge, it will be necessary to enhance skills to obtain and use high-quality health information and to improve the environment for using ICT-based communication devices.

Objective:
To evaluate the long-term efficacy and safety of niraparib in Japanese women with heavily pretreated ovarian cancer.
Methods:
This was the follow-up analysis of a phase 2, multicenter, open-label, single-arm study in Japanese women with homologous recombination-deficient, platinum-sensitive, relapsed, high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who had completed 3–4 lines of chemotherapy and were poly(ADP-ribose) polymerase inhibitor naïve. Participants received niraparib (starting dose, 300 mg) once daily in continuous 28-day cycles until objective disease progression, unacceptable toxicity, or consent withdrawal. The primary endpoint was confirmed objective response rate (ORR), as assessed using Response Evaluation Criteria in Solid Tumors version 1.1. Safety evaluations included treatment-emergent adverse events (TEAEs).
Results:
20 patients were enrolled in the study and included in both efficacy and safety analyses. Median total study duration was 759.5 days. Median dose intensity was 201.3 mg/ day. Confirmed ORR was 60.0% (90% confidence interval [CI]=39.4–78.3); 2 patients had complete response and 10 patients had partial response. Median duration of response was 9.9 months (95% CI=3.9–26.9) and the disease control rate was 90.0% (95% CI=68.3–98.8).The most common TEAEs were anemia (n=15), nausea (n=12), and decreased platelet count (n=11). TEAEs leading to study drug dose reduction, interruption, or discontinuation were reported in 16 (80.0%), 15 (75.0%), and 2 patients (10.0%), respectively.
Conclusion
The long-term efficacy and safety profile of niraparib was consistent with previous findings in the equivalent population in non-Japanese patients. No new safety signals were identified.

Background/Aims:
The frequency and details of nonalcoholic fatty liver disease (NAFLD) complications in patients with inflammatory bowel disease (IBD) remain unclear. This study aimed to clarify characteristics of NAFLD in patients with IBD.
Methods:
We retrospectively identified and enrolled patients with IBD diagnosed with or without NAFLD by undergoing abdominal computed tomography (CT) at our institution between 2005 and 2020. The primary endpoint was the complication rate of NAFLD in patients with IBD. Secondary endpoints were the clinical characteristics of nonobese patients with IBD and comorbid NAFLD and their association with nutritional and inflammatory parameters.
Results:
Twenty-one (21.9%) of 96 eligible patients with IBD also had NAFLD. In nonobese patients (defined as patients with a body mass index <25 kg/m2), C-reactive protein (CRP; P<0.001) and alanine aminotransferase (P=0.018) levels were higher and the albumin level (P=0.005) and prognostic nutritional index (PNI; P=0.002) values were lower in patients with NAFLD than in those without NAFLD. The PNI value was positively correlated (P<0.001) and the CRP level was negatively correlated (P=0.001) with the hepatosplenic ratio. However, in the NAFLD combined group, PNI (P<0.05) and CRP values (P<0.001) were improved over time after CT imaging by continuing IBD treatment.
Conclusions
Worsening nutritional and inflammatory status in IBD patients is associated with complications of NAFLD. Diagnosis of NAFLD in IBD patients using CT imaging might be useful not only for early detection of NAFLD but also in assessing the need for therapeutic intervention for IBD.

The patient was an 80-year-old man who was diagnosed with cStage IIIB non-small cell lung cancer (NSCLC) and early gastric cancer. The advanced lung cancer was treated with chemotherapy while the gastric cancer was monitored. Immune checkpoint inhibitors were effective against the lung cancer for a long period, but new gastric cancer appeared and progressed to an advanced stage, necessitating total gastrectomy 5 years after the diagnosis of NSCLC. The patient is currently being treated with a molecular targeted agent for progression of the lung cancer after gastrectomy. In the future, the number of cases with multiple primary cancers will increase alongside aging of the population and advances in cancer treatment, and a system for tumor-agnostic treatment selection and medical treatment will be necessary.
