The Japan Society of Gynecologic Oncology (JSGO) Guidelines 2022 for the Treatment of Uterine Cervical Cancer are revised from the 2017 guideline. This guideline aimed to provide standard care for cervical cancer, indicate appropriate current treatment methods for cervical cancer, minimize variances in treatment methods among institutions, improve disease prognosis and treatment safety, reduce the economic and psychosomatic burden of patients by promoting the performance of appropriate treatment, and enhance mutual understanding between patients and healthcare professionals. The guidelines were prepared through the consensus of the JSGO Guideline Committee, based on a careful review of evidence gathered through the literature searches and the medical health insurance system and actual clinical practice situations in Japan. The guidelines comprise seven chapters and 5 algorithms.The main features of the 2022 revision are as follows: 1) added discussed points at the final consensus meeting; 2) revised the treatment methods based on the International Federation of Gynecology and Obstetrics 2018 staging system; 3) examined minimally invasive surgery based on Laparoscopic Approach to Cervical Cancer trial; 4) added clinical question (CQ) for treatments of rare histological types, gastric type, and small-cell neuroendocrine carcinoma; 5) added CQ for intensity-modulated radiation therapy; 6) added CQ for cancer genomic profiling test; and 7) added CQ for cancer survivorship. Each recommendation is accompanied by a classification of recommendation categories based on the consensus reached by the Guideline Committee members. Here, we present the English version of the JSGO Guidelines 2022 for the Treatment of Uterine Cervical Cancer.

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.

Objective: The practices pertaining to hereditary breast and ovarian cancer (HBOC) in Japan have been rapidly changing owing to the clinical development of poly(ADP-ribose) polymerase inhibitors, the increasing availability of companion diagnostics, and the broadened insurance coverage of HBOC management from April 2020. A questionnaire of gynecologic oncologists was conducted to understand the current status and to promote the widespread standardization of future HBOC management. Methods: A Google Form questionnaire was administered to the members of the Japan Society of Gynecologic Oncology. The survey consisted of 25 questions in 4 categories: respondent demographics, HBOC management experience, insurance coverage of HBOC management, and educational opportunities related to HBOC. Results: A total of 666 valid responses were received. Regarding the prevalence of HBOC practice, the majority of physicians responded in the negative and required human resources, information sharing and educational opportunities, and expanded insurance coverage to adopt and improve HBOC practice. Most physicians were not satisfied with the educational opportunities provided so far, and further expansion was desired. They remarked on the psychological burdens of many HBOC managements. Physicians reported these burdens could be alleviated by securing sufficient time to engage in HBOC management, creating easy-to-understand explanatory material for patients, collaboration with specialists in genetic medicine, and educational opportunities. Conclusion Gynecologic oncologists in Japan are struggling to deal with psychological burdens in HBOC practice. To promote the clinical practice of HBOC management, there is an urgent need to strengthen human resources and improve educational opportunities, and expand insurance coverage for HBOC management.

An 89-year-old man complained of pulsatile masses in his right groin. Computed tomography (CT) scans revealed an aneurysm of the right deep femoral artery. He was admitted to our hospital with a diagnosis of deep femoral artery aneurysm (DFAA). The clinical frailty scale score was 6 (moderately frail), and he also suffered chronic obstructive pulmonary disease (COPD). Considering his complicated frail and impaired pulmonary function, conventional graft replacement and aneurysmectomy were thought to be quite a high risk. Thus, we selected endovascular treatment. It was not possible to secure a sufficient proximal landing zone for measurement, we did not select a stent-graft treatment. Therefore, we performed hybrid therapy with proximal neck ligation and distal outflow coil embolization. The postoperative course was uneventful, and CT disclosed complete occlusion of the aneurysm.

Introduction : Prevention of embolic stroke is the key issue to perform aortic arch replacement in patients with a shaggy aorta. The aim of this study is to report the utility of the isolation technique for total arch replacement in patients with a shaggy aorta. Methods : Clinical results of seven patients (71.7 years old, all men) with a shaggy aorta who underwent total arch replacement between January 2017 and November 2018 were retrospectively reviewed. The operative indications were a distal arch or proximal descending aortic aneurysm in 6 patients and a thrombus inside brachiocephalic artery in one. A cerebral perfusion was established by inserting a cannula directly into all supra-aortic branches before starting systemic perfusion. Result : Utilizing the isolation technique with clamping of all branches in 4 patients and the functional isolation technique with clamping of two branches in 3, total arch replacement was performed in all patients (operation time : 513 min, selective cerebral perfusion time : 162 min). No operative death was observed and no newly developed stroke was encountered. Conclusion : The isolation technique is a useful method to prevent stroke during total arch replacement in patients with a shaggy aorta.

PURPOSE: Patients with pathological stage T1N+ or T2–3N0 gastric cancer may experience disease recurrence following curative gastrectomy. However, the current Japanese Gastric Cancer Treatment Guidelines do not recommend postoperative adjuvant chemotherapy for such patients. This study aimed to identify the prognostic factors for patients with pT1N+ or pT2–3N0 gastric cancer using a multi-institutional dataset. MATERIALS AND METHODS: We retrospectively analyzed the data obtained from 401 patients with pT1N+ or pT2–3N0 gastric cancer who underwent curative gastrectomy at 9 institutions between 2010 and 2014. RESULTS: Of the 401 patients assessed, 24 (6.0%) experienced postoperative disease recurrence. Multivariate analysis revealed that age ≥70 years (hazard ratio [HR], 2.62; 95% confidence interval [CI], 1.09–7.23; P=0.030) and lymphatic and/or venous invasion (lymphovascular invasion (LVI): HR, 7.88; 95% CI, 1.66–140.9; P=0.005) were independent prognostic factors for poor recurrence-free survival. There was no significant association between LVI and the site of initial recurrence. CONCLUSIONS LVI is an indicator of poor prognosis in patients with pT1N+ or pT2–3N0 gastric cancer.

For the purpose of protecting the rights of Lentinula edodes breeders, we developed a new simple sequence repeat (SSR) marker set consisting only of genetically independent tetranucleotide or longer core motifs. Using available genome sequences for five L. edodes strains, we designed primers for 13 SSR markers that amplified polymorphic sequences in 20 L. edodes cultivars. We evaluated the independence of every possible marker pair based on genotype data. Consequently, eight genetically independent markers were selected. The polymorphic information content values of the markers ranged from 0.269 to 0.764, with an average of 0.409. The markers could distinguish among 20 L. edodes cultivars and produced highly repeatable and reproducible results. The markers developed in this study will enable the precise identification of L. edodes cultivars, and may be useful for protecting breeders' rights.
