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.

[Introduction] Clarifying the nature of polarity for electro acupuncture, document retrieval and discussion was conducted on electric corrosion.[Materials and Methods] "Energization Current on Acupuncture Needle", "Direct current"and "Electrolytic Corrosion" were used for Key Words searching citation in Medical Journal Web, Google Scholar, PubMed, and Elsevier.[Results] Information retrieval resulted in one article Nine Japanese articles were selected excluding those are not related acupuncture and overlapped content with other. The results of nine studies used saline solution. Two studies were examined using the piece of chicken or pork meat. Two were animal research. Three used human subjects. Six Foreign articles were selected. [Discussion] All the reports indicated that the needle applied positive polarity current did not show electrolytic corrosion so far as not conducting excessive huge current directly from such as car battery. Although, it was shown that no noticeable electrolytic corrosion was elicited on the surface of needles that were the negative polarity even when an excessive current was applied.[Conclusion] It is the Positive needle electrode that elutes metal. Positive electrode should be a skin surface indifferent electrode as case of applying direct current using the acupuncture needle on the human body. Acupuncture needles made of stainless steel wire material SUS316 are supposed or strongly suggested more suitable for energizing than other stainless steel wire materials.
