Objective:
The incidence and mortality rates of endometrial cancer are increasing globally, including in Japan. Quality of cancer care is promoted through guideline adherence. This study aimed to establish quality indicators (QIs) for endometrial cancer and explore the factors contributing to treatment nonadherence.
Methods:
QIs and pattern-of-care indicators (PCIs) were developed using the Research and Development/University of California Los Angeles modified Delphi method. QIs reflect desirable healthcare patterns, whereas PCIs address treatment areas with lacking evidence.Data from the Hospital-Based Cancer Registry and Diagnosis Procedure Combination Survey were used. Patients diagnosed or treated between January 1 and December 31, 2020 were included. The reasons for nonadherence were collected. Logistic regression was used to analyze the factors influencing adherence, including age, body mass index, comorbidities, facilities, and recurrence risk.
Results:
Of the 35 proposed QI candidates, 8 QIs and 9 PCIs were selected, predominantly focusing on surgical aspects. Adherence rates varied, with peritoneal lavage cytology being the highest (93.1%), and postoperative hormone replacement therapy (HRT) for patients aged <45 years being the lowest (30.9%), when focusing on process indicators. Reasons for nonadherence included patient preference and medical comorbidities as significant factors. Multivariate analysis highlighted age, clinical stage, and Barthel index as significant contributors to nonadherence.
Conclusion
We developed QIs to comprehensively assess endometrial cancer treatment.Adherence rates are favorable; however, HRT has a low adherence rate. Factors leading to nonadherence include advanced age and incomplete activities of daily living, particularly in advanced stages.

Objective:
Cervical cancer rates in Japan (16.0/100,000) exceed the global average rate (11.3/100,000, according to the High/Very-High Human Development Index in 2020). This necessitates the evaluation of care quality and the quality indicators (QIs) for cervical cancer that were developed in 2013 to serve this purpose. This study updated these indicators using current evidence and consensus while longitudinally examining trends in practice patterns.
Methods:
The revision involved reviewing existing QIs and patterns of care indicators and incorporating new indicators using the modified Delphi method. Adherence to these indicators was assessed using a linked hospital-based cancer registry-based diagnostic procedure combination database covering approximately 70% of patients with cancer in Japan. The longitudinal trends of the existing indicators were evaluated using the linear probability model.
Results:
Seven new indicators were added to the existing twelve. Two of the new indicators mainly focused on early-stage surgical intervention, while one focused on advanced-stage bevacizumab combination therapy, with adherence rates of 81.7%, 0.8%, and 45.9%.Longitudinal analyses revealed significant improvements with the use of cisplatin in concurrent chemoradiotherapy for advanced-stage cervical cancer (+1%/year), oral anticancer agents as maintenance therapy after primary treatment for early-stage cervical cancer (−0.8%/ year), and hysterectomy for adenocarcinoma in situ in patients above 44 years old (−2%/year).
Conclusion
The QIs for cervical cancer in Japan have been revised based on 2022 evidence.The existing and new indicators should be continually evaluated to correspond to the latest knowledge. This will facilitate the standardization and promotion of bottom-up improvements in cervical cancer care.

STUDY DESIGN: Experimental human study. PURPOSE: To determine whether angiopoietin-like protein 2 (ANGPTL2) is highly expressed in the hyperplastic facet joint (FJ) synovium and whether it activates interleukin-6 (IL-6) secretion in FJ synoviocytes. OVERVIEW OF LITERATURE: Mechanical stress-induced synovitis is partially, but significantly, responsible for degenerative and subsequently osteoarthritic changes in the FJ tissues in patients with lumbar spinal stenosis (LSS). However, the underlying molecular mechanism remains unclear. IL-6 is highly expressed in degenerative FJ synovial tissue and is responsible for local chronic inflammation. ANGPTL2, an inflammatory and mechanically induced mediator, promotes the expression of IL-6 in many cells. METHODS: FJ tissues were harvested from five patients who had undergone lumbar surgery. Immunohistochemistry for ANGPTL2, IL-6, and cell markers was performed in the FJ tissue samples. After cultured synoviocytes from the FJ tissues were subjected to mechanical stress, ANGPTL2 expression and secretion were measured quantitatively using real-time quantitative reverse-transcription–polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA), respectively. Following ANGPTL2 administration in the FJ synoviocytes, anti-nuclear factor-κB (NF-κB) activation was investigated using immunocytochemistry, and IL-6 expression and secretion were assayed quantitatively with or without NF-κB inhibitor. Moreover, we assessed whether ANGPTL2-induced IL-6 modulates leucocyte recruitment in the degenerative process by focusing on the monocyte chemoattractant protein-1 (MCP-1) expression. RESULTS: ANGPTL2 and IL-6 were highly expressed in the hyperplastic FJ synovium samples. ANGPTL2 was co-expressed in both, fibroblast-like and macrophage-like synoviocytes. Further, the expression and secretion of ANGPTL2 in the FJ synoviocytes increased in response to stimulation by mechanical stretching. ANGPTL2 protein promoted the nuclear translocation of NF-κB and induced IL-6 expression and secretion in the FJ synoviocytes. This effect was reversed following treatment with NF-κB inhibitor. Furthermore, ANGPTL2-induced IL-6 upregulated the MCP-1 expression in the FJ synoviocytes. CONCLUSIONS: Mechanical stress-induced ANGPTL2 promotes chronic inflammation in the FJ synovium by activating IL-6 secretion, leading to FJ degeneration and subsequent LSS.

We experienced 6 cases of intractable perioperative myocardial ischemia with coronary spasm that was successfully treated with fasudil, a Rho-kinase inhibitor. Three of the patients (aged 49-81 years) showed ST elevation on electrocardiograms and abrupt circulatory collapse after off-pump coronary artery bypass grafting. Emergeny coronary angiogram revealed severe spasm of their own coronary arteries and/or bypass grafts. Since intracoronary and/or intragraft injection of isosorbide dinitrate (ISDN) was ineffective, we administered fasudil into the spastic vessels, and that completely resolved the spasm. The other 3 patients (aged 55-77 years) suffered myocardial ischemia during the operation, though intravenous vasodilators including ISDN, diltiazem and nicorandil had been administered continuously. Their ischemia occurred when the aorta was declamped, the pericardium opened, or the bypass graft was anastomosed, respectively. We decided to use fasudil in these cases since ISDN was ineffective, or severe spasm was found on intraoperative inspection. Administration of fasudil successfully relieved the ischemia, and subsequently all 3 patients could be weaned from the cardiopulmonary bypass during the operation. Fasudil completely resolved the myocardial ischemia in all 6 patients. In conclusion, fasudil, a Rho-kinase inhibitor, is a useful agent for perioperative myocardial ischemia including coronary spasm that is resistant to intensive conventional vasodilator therapy. We should administer fasudil and relieve spasms as early as possible to rescue patients with intractable ischemia.

We report a case of right cervical (C2-C4 area) acute herpetic pain successfully treated by therapeutic selective nerve blocks. A47-year-old man complained of right cervical persistent pain and frequent intermittent pain associated with herpes zoster. This pain was resistant to standard therapies such as satellite ganglion block and epidural block. On the 10th day after onset, the patient was treated by X-ray-guided therapeutic C3 and C4 selective nerve root blocks, resulting in an almost immediate relief of pain. The patient remained pain-free, and postherpetic neuralgia (PHN) was prevented. Although there are various treatments for PHN, none produces definitive effects. Relief of acute herpetic pain and prevention of PHN are important in the treatment of herpes zoster.

We have studied post tetanic count (PTC) and single twitch height at the onset of reflex movement to carinal stimulation after administration of vecronium to 10 female patients under total intravenous anesthesia. During spontaneous recovery from vecronium-induced neuromuscular block, the carina was stimulated at every 120s. It took 18.7±5.5 minutes before reflex movement started, T1% was 1.9±2.2%, and PTC was 11.59±5.3 counts. In 5 cases, T1% did not appear at the onset of reflex movement.
