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:
Medroxyprogesterone acetate (MPA) is an effective fertility-preserving treatment for early endometrial cancer and atypical endometrial hyperplasia (AEH), and rarely leads to the development of extrauterine lesions (ELs). We aimed to clarify the characteristics of patients who developed ELs post-MPA therapy.
Methods:
We analyzed the clinicopathological factors and prognoses of 319 patients with endometrioid carcinoma grade 1 (EMG1) and AEH treated with MPA at our institution. All patients underwent imaging before MPA treatment to rule out ELs.
Results:
Seven patients (2.2%) with EMG1 showed EL after MPA treatment. Two patients developed EL during the initial treatment, 2 during repeated treatment, and 3 during followup. Two patients had peritoneal dissemination, 3 had regional lymph node metastasis, 1 had distant metastasis at the Virchow lymph node, and 1 had ovarian metastasis. ELs were diagnosed using imaging tests in 6 patients and elevated tumor markers in 3 (overlapping) patients. One patient was diagnosed with ELs pathologically after hysterectomy. Upon EL diagnosis, patients underwent standard treatment, including hysterectomy and chemotherapy, that was followed by a diagnosis of EMG1 for 5, EMG2 for 1, and EMG3 for 1 patient. One patient died 15 months after start of therapy and another died 119 months posttreatment initiation, while the others have been survived.
Conclusion
Only 2.2% of all patients developed ELs post-MPA treatment, but some cases were fatal. It is essential to conduct imaging tests and screen for tumor markers during and after MPA treatment regularly and also when cancer progression is suspected.
3.A phase II trial evaluating the efficacy and safety of repeated high dose medroxyprogesterone acetate (MPA) therapy for patients with recurrent early-stage endometrial cancer or atypical endometrial hyperplasia:Japanese Gynecologic Oncology Group study (JGOG2051/KGOG2031, REMPA trial)

Background:
Fertility preserving therapy using medroxyprogesterone acetate (MPA) is an important option for young patients with endometrial cancer or atypical endometrial hyperplasia (AEH). However, the effectiveness and feasibility of repeated MPA therapy for patients with intrauterine recurrence following initial MPA therapy is controversial. Only a few single-institution retrospective studies have been conducted on repeated MPA therapy, therefore, multicenter prospective studies for repeated MPA therapy are highly needed.The aim of this study is to assess whether repeated MPA therapy is effective and feasible for patients with intrauterine recurrence following initial MPA therapy.
Methods
This is a prospective, single-arm, a multicenter phase II trial on repeated MPA therapy for intrauterine recurrence following fertility-preserving therapy for AEH or stage IA (the International Federation of Gynecology and Obstetrics [FIGO] 2008) non-myoinvasive endometrioid carcinoma grade 1. Patients are treated with oral MPA (500–600 mg/day).Pathologically assessment via dilation and curettage will be performed every 2 months until complete response. The major inclusion criteria are 1) intrauterine recurrence of AEH or stage IA (FIGO 2008) endometrioid carcinoma grade 1 without myometrial invasion or extrauterine spread confirmed by imaging tests after complete remission with the previous MPA therapy. 2) The number of recurrences should be up to twice. 3) histologically diagnosed as AEH or endometrioid carcinoma grade 1, 4) 20–42 years of age, and 5) strong desire and consent for fertility-sparing treatment. The primary endpoint is 2-year recurrence-free survival rate. A total of 115 patients will be enrolled from multiple institutions in Japan and Korea within 4 years and followed up for 2 years.

Background/Aims:
The use of endoscopic intervention (EI) for acute biliary pancreatitis (ABP) remains controversial because the severity of biliary obstruction/cholangitis/pancreatitis is not reflected in the indications for early EI (EEI).
Methods:
A total of 148 patients with ABP were included to investigate 1) the differences in the rate of worsening cholangitis/pancreatitis between the EEI group and the early conservative management (ECM) group, especially for each severity of cholangitis/pancreatitis, and 2) the diagnostic ability of imaging studies, including endoscopic ultrasound (EUS), to detect common bile duct stones (CBDSs) in the ECM group.
Results:
No differences were observed in the rate of worsening cholangitis between the EEI and ECM groups, regardless of the severity of cholangitis and/or the existence of impacted CBDSs. Among patients without impacted CBDSs and moderate/severe cholangitis, worsening pancreatitis was significantly more frequent in the EEI group (18% vs. 4%, p=0.048). In patients in the ECM group, the sensitivity and specificity for detecting CBDSs were 73% and 98%, respectively, for EUS, whereas the values were 13% and 92%, respectively, for magnetic resonance cholangiopancreatography.
Conclusions
EEI should be avoided in the absence of moderate/severe cholangitis and/or impacted CBDSs because of the high rate of worsening pancreatitis. EUS can contribute to the accurate detection of residual CBDSs, for the determination of the need for elective EI.

OBJECTIVE: Reports on the repeated administration of medroxyprogesterone acetate (MPA) for intrauterine recurrence after fertility-preserving therapy for atypical endometrial hyperplasia (AEH) and early grade 1 endometrioid carcinoma (G1) are lacking. We aimed to clarify the outcomes of repeated MPA therapy in cases of intrauterine recurrence after fertility-preserving therapy with MPA against AEH/early G1. METHODS: Patients with AEH or stage IA well-differentiated endometrioid carcinoma without myometrial invasion who underwent first-line MPA therapy for primary lesions or intrauterine recurrence were divided into initial treatment and repeated treatment groups (162 and 82 patients, respectively). Oral MPA administration (400−600 mg/day) was continued until pathological tumor disappearance. Data regarding clinicopathological factors, adverse events, and outcomes following the initial and repeated hormonal treatments were extracted from medical records and analyzed. RESULTS: Complete response rates in the initial and repeated treatment groups were 98.5% and 96.4%, respectively, among patients with AEH, and were 90.7% and 98.1%, respectively, among patients with G1. In the initial treatment group, 5-year recurrence-free survival (RFS) rates were 53.7% and 33.2% among patients with AEH and G1, respectively. In the repeated treatment group, RFS rates were 14.0% and 11.2% among patients with AEH and G1, respectively. Among patients with AEH, the pregnancy rate tended to be lower in the repeated treatment group than in the initial treatment group (11.1% vs. 29.2%; p=0.107), while no significant group difference was observed among patients with G1 (20.8% vs. 22.7%). CONCLUSION: Repeated treatment is sufficiently effective for intrauterine recurrence after hormonal therapy for AEH/early G1.

STUDY DESIGN: Retrospective case series. PURPOSE: To clarify the influence of cervical spinal canal stenosis (CSCS) on neurological functional recovery after traumatic cervical spinal cord injury (CSCI) without major fracture or dislocation. OVERVIEW OF LITERATURE: The biomechanical etiology of traumatic CSCI remains under discussion and its relationship with CSCS is one of the most controversial issues in the clinical management of traumatic CSCI. METHODS: To obtain a relatively uniform background, patients non-surgically treated for an acute C3-4 level CSCI without major fracture or dislocation were selected. We analyzed 58 subjects with traumatic CSCI using T2-weighted mid-sagittal magnetic resonance imaging. The sagittal diameter of the cerebrospinal fluid (CSF) column, degree of canal stenosis, and neurologic outcomes in motor function, including improvement rate, were assessed. RESULTS: There were no significant relationships between sagittal diameter of the CSF column at the C3-4 segment and their American Spinal Injury Association motor scores at both admission and discharge. Moreover, no significant relationships were observed between the sagittal diameter of the CSF column at the C3-4 segment and their neurological recovery during the following period. CONCLUSIONS: No relationships between pre-existing CSCS and neurological outcomes were evident after traumatic CSCI. These results suggest that decompression surgery might not be recommended for traumatic CSCI without major fracture or dislocation despite pre-existing CSCS.

BACKGROUND/AIMS: There are few reports on the correlation between chewing gum and the gastrointestinal functions. But previous report showed use of chewing gum to be an effective method for controlling gastrointestinal symptoms. The aim of this study was to determine the correlation between chewing gum and gastric emptying using the continuous real time 13C breath test (BreathID system). METHODS: Ten healthy male volunteers participated in this randomized, 2-way crossover study. The subjects fasted overnight and were randomly assigned to chewing gum (Xylish, 2-3/1 tablet) for an hour following intake of a test meal (200 kcal/200 mL) or intake of the test meal alone. Gastric emptying was monitored for 4 hours after administration of the test meal by the 13C-acetic acid breath test performed continually using the BreathID system. RESULTS: No significant differences in the calculated parameters, namely, T1/2 (median, 111.82 vs 109.26 minutes; P = 0.575), Tlag (median, 53.28 vs 56.53 minutes; P = 0.333), gastric emptying coefficient (median, 3.58 vs 3.65; P = 0.285), regression-estimated constant beta (median, 1.85 vs 1.80; P = 0.575) and regression-estimated constant kappa (median, 0.61 vs 0.62; P = 0.959) were observed between the test meal alone group and the test meal and chewing gum group. CONCLUSIONS: This study showed that chewing gum had no effect on the rate of gastric emptying. Therefore, since chewing gum did not enhance the speed of gastric emptying, it may ameliorate gastrointestinal symptoms through other mechanisms, such as saliva and autonomic nervous system.

The purpose of this study was to investigate the effect of individual feedback intervention (IFB) or general video intervention (GV) on promoting daily physical activity. One hundred and thirty-six community-dwelling people volunteered as subjects and participated in the 2-month walking program provided as a correspondence course. The subjects were randomly allocated to one of four groups, which consisted of either IFB or GV. Each of the groups was based on behavioral science. The stage of change in exercise, self-efficacy for exercise and daily physical activity were measured before and after intervention 4 months later during the follow-up period. There were statistically significant effects of both ‘time’ (F=3.71, p=0.026) and ‘time’בIFB’ (F=3.76, p=0.025) in self-efficacy for exercise; while there was no significant effect of interaction between ‘time’בGV’. As for daily physical activity, there was no significant effect of the interaction both of ‘time’בIFB’ and ‘time’בGV’. These results suggest the IFB of promoting self-efficacy for exercise.
