Objective:
The prognostic value and clinical usage of peritoneal cytology in endometrial cancer are uncertain. This study aimed to determine whether positive cytology is associated with the prognosis for endometrial cancer.
Methods:
A Japanese nationwide retrospective registry study was conducted between 2012 and 2019. Clinicopathological data were analyzed for patients who were registered in the Japan Society of Obstetrics and Gynecology (JSOG) gynecological tumor registry and underwent initial treatment for endometrial cancer.
Results:
In total, 83,027 patients who met the inclusion criteria were identified. Data on peritoneal cytology status and overall survival (OS) were available for 74,984 and 36,995 patients, respectively. Positive peritoneal cytology was found in 11,536 (15.4%) patients. A higher proportion of patients who had positive peritoneal cytology were related to advanced stages, high-grade histology, deep myometrial invasion, lymph node (LN) metastasis, and poor risk of recurrence. After controlling for age, stage, myometrial invasion, LN metastasis, distant metastasis, and risk of recurrence, positive peritoneal cytology was associated with poor prognosis (p<0.001). Multivariate Cox regression analysis revealed that clinicopathological factors (i.e., age, International Federation of Gynecology and Obstetrics stage, histological type, myometrial invasion, LN metastasis, distant metastasis, and peritoneal cytology), including positive peritoneal cytology, were also significant prognostic factors for OS.
Conclusion
Positive peritoneal cytology was a prognostic factor for endometrial cancer for the JSOG gynecological tumor registry.

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:
In this study, we collected data over 8 years (2012–2019) from the Japan Society of Obstetrics and Gynecology (JSOG) tumor registry to determine the status of endometrial cancer in Japan, and analyzed detailed clinicopathological factors.
Methods:
The JSOG maintains a tumor registry that gathers information on endometrial cancer treated at the JSOG-registered institutions. Data from the patients whose endometrial cancer treatment was initiated from 2012 to 2019 were analyzed retrospectively.
Results:
A total of 82,969 patients with endometrial cancer underwent treatment from 2012 to 2019. Chemotherapy alone or in combination with hormonal therapy is more common among endometrial cancer patients under 40 years compared with those over 40 years. The number of patients with endometrial cancer, treated with laparoscopic or robot-assisted surgery was observed to have increased yearly. Small cell carcinomas and undifferentiated carcinomas were more likely to be diagnosed at an advanced stage. Lymphadenectomy was most commonly performed for stage IIIC2 disease, whereas positive peritoneal washing cytology was most common for stage IVB and serous carcinoma.
Conclusion
Multi-year summary reports provided detailed clinicopathological information regarding endometrial cancer that could not be obtained in a single year. These reports were useful in understanding treatment strategies and trends over time based on age, histology, and stage.

[Introduction] The effects of combining acupuncture and kampo medicine on in vitro fertilization (IVF) outcomes is unclear. Therefore, we aimed to investigate their combined effects on promoting conception in patients with multiple IVF attempts.[Methods] Participants with at least two IVF attempts who gave informed consent were included in this study. Administering acupuncture and kampo medicine, the study was conducted across three facilities from 2013 to 2017 using a case series design. Case 1: A 40-year-old woman presented after 13 months of infertility, having experienced a natural conception and subsequent miscarriage 10 months prior, which led to IVF. After a second embryo transfer, she miscarried again 3 months before visiting. She began kampo medicine and acupuncture for support in our department. Case 2: A 46-year-old woman with a 36-month infertility history did not achieve pregnancy after three IVF cycles. Case 3: A 37-year-old woman with a 20-month infertility history failed to conceive after two IVF attempts. Case 4: A 26-year-old woman, new to infertility treatment, received acupuncture for fertility preservation, experiencing headache, shoulder stiffness, and widespread pain. Case 5: A 38-year-old woman with a 108-month infertility history suffered from shoulder stiffness due to prolonged IVF therapy. The main outcome measured was pregnancy. Standard acupuncture points utilized included L14 (Hegu), CV12 (Zhongwan), CV7 (Yinjiao), ST27 (Daju), ST29 (Guilai), BL18 (Ganshu), BL20 (Pishu), BL23 (Shenshu), BL33 (Zhongliao), SP10 (Xuehai), ST36 (Zusanli), and SP6 (Sanyinjiao). [Results] Four out of five participants achieved pregnancy. [Discussion] Our findings reveal a positive effect of combining acupuncture and kampo medicine on enhancing pregnancy rates in patients undergoing multiple IVF treatments, suggesting clinical effectiveness in fostering an appropriate environment for conception.

Nephroblastomatosis (NBM) is a precursor of Wilms tumor. We herein report a case in which Wilms tumor was initially suspected and the affected kidney was removed.The tumor was subsequently diagnosed as intralobar NBM and a favorable outcome was achieved with postoperative chemotherapy. A 2-year-old boy who presented with gross hematuria was found to have an enlarged left kidney with hydronephrosis.Needle biopsy of the left kidney suggested Wilms tumor and left nephrectomy was performed. The tumor was histopathologically diagnosed as intralobar NBM.Although NBM is regarded as a precancerous lesion, a definite treatment plan has not yet been established. In the present case, we used a similar chemotherapy regimen to that for Wilms tumor. Eight years after the completion of chemotherapy, Wilms tumor has not developed or recurred. Appropriate management plans need to be developed by accumulating similar cases.

Clinical Endoscopy 2021;54(3):363-370
Background/Aims:
Probe-based confocal laser endomicroscopy (pCLE) requires the administration of intravenous (IV) fluorescein. This study aimed to determine the optimal dose of IV fluorescein for both upper and lower gastrointestinal (GI) tract pCLE.
Methods:
Patients 20 to 79 years old with gastric high-grade dysplasia (HGD) or colorectal neoplasms (CRNs) were enrolled in the study. The dose de-escalation method was employed with five levels. The primary endpoint of the study was the determination of the optimal dose of IV fluorescein for pCLE of the GI tract. The reduced dose was determined based on off-line reviews by three endoscopists. An insufficient dose of fluorescein was defined as the dose of fluorescein with which the pCLE images were not deemed to be visible. If all three endoscopists determined that the tissue structure was visible, the doses were de-escalated.
Results:
A total of 12 patients with gastric HGD and 12 patients with CRNs were enrolled in the study. Doses were de-escalated to 0.5 mg/kg of fluorescein for both non-neoplastic duodenal and colorectal mucosa. All gastric HGD or CRNs were visible with pCLE with IV fluorescein at 0.5 mg/kg.
Conclusions
In the present study, pCLE with IV fluorescein 0.5 mg/kg was adequate to visualize the magnified structure of both the upper and lower GI tract.

In daily medical examinations of orthopedic surgery, treatment for chronic pain is sometimes needed. We report a case of chronic pain developed after an open fracture 15 years ago and successfully treated with sokeikakketsuto. A 35-year-old man unfortunately sustained an open fracture in his right lower leg in a traffic accident at his age of 20 years. He underwent 12-13 surgeries for osteosynthesis, post-operative focal infection, and leg extension. Subsequently, he developed periodic pain in his right ankle joint. He consulted our clinic because of the severe pain; although non-steroidal anti-inflammatory drugs were ineffective, sokeikakketsuto was dramatically effective. To treat chronic pain after an old fracture, sokeikakketsuto may be considered as a choice of treatment.
