High expression of folate receptor alpha is associated with poor prognosis in patients with cervical cancer / 부인종양

Objective@#Folate receptor α (FRα) is a membrane protein expressed in various solid tumors but has limited expression in normal cells. Therefore, FRα is an attractive target for cancer treatment. This study aimed to investigate the relationship between FRα expression and the clinicopathological characteristics and survivals of cervical cancer. @*Methods@#This retrospective study included patients with cervical cancer who underwent primary surgery between 2000 and 2020 at our institution. Immunohistochemical staining of FRα was performed using an anti-folate-binding protein/FBP antibody. FRα-positive staining was defined as ≥5% of tumor staining and FRα-high as ≥50% tumor staining with ≥2+ intensity. The association between FRα expression and survival was assessed using multivariate Cox regression analysis, adjusting for established prognostic factors. @*Results@#Overall, 123 patients were identified, and 140 tumor samples, including 17 paired primary and metastatic samples, were evaluated. As histological types, 67 patients had squamous cell carcinoma (SCC), and 56 patients had non-SCC. All primary tumors were FRα-positive. High FRα expression was observed in 25% of the cases and differed according to histology (SCC vs. non-SCC, 14.9% vs. 37.5%, p=0.004). FRα expression was significantly higher in metastatic tumors than in primary (170 [IQR, 140–205] vs. 125 [IQR, 110–150], p=0.0006). High FRα expression was significantly associated with worse overall survival (hazard ratio, 6.73; 95% confidence interval, 2.21–20.53; p=0.001). @*Conclusion@#In cervical cancer, FRα expression was elevated in metastatic tumors and high expression was associated with a worse prognosis. Our study supports the development of FRα-targeted therapy for advanced cervical cancer.

Prognostic factors of synchronous endometrial and ovarian endometrioid carcinoma / 부인종양

OBJECTIVE: Gynecologists occasionally encounter synchronous endometrial and ovarian endometrioid carcinoma (SEO-EC) patients who show favorable prognosis than locally advanced or metastatic disease patients. This study aimed to elucidate prognostic factors of SEO-EC and identify patients who have a sufficiently low risk of recurrence without receiving adjuvant chemotherapy. METHODS: We retrospectively reviewed 46 patients with pathologically confirmed SEO-EC who underwent surgery at the National Cancer Center Hospital between 1997 and 2016. Immunohistochemical evaluation of DNA mismatch repair (MMR) protein expression were performed for both endometrial and ovarian tumors. Patient outcomes were analyzed according to clinicopathologic factors. RESULTS: From the multivariate analysis, cervical stromal invasion indicated a worse prognosis for progression-free survival (hazard ratio [HR]=6.85; 95% confidence interval [CI]=1.50–31.1) and overall survival (HR=6.95; 95% CI=1.15–41.8). Lymph node metastasis and peritoneal dissemination did not significantly affect survival. MMR deficiency was observed in 13 patients (28.3%), with both endometrial and ovarian tumors showing the same MMR expression status. MMR deficiency was not significantly associated with survival. Of 23 patients with lesions confined to only the uterine body and adnexa, only 2 had recurrence in the group receiving adjuvant therapy, while none of the 10 patients who did not receive adjuvant therapy had recurrence. CONCLUSION: SEO-EC patients with tumors localized to the uterine body and adnexa lesions had a low risk for recurrence and may not require adjuvant therapy. SEO-EC may have prognostic factors different from those of endometrial and ovarian cancer.

Prognostic factors for patients with early-stage uterine serous carcinoma without adjuvant therapy / 부인종양

OBJECTIVE: Uterine serous carcinoma (USC) is an aggressive type 2 endometrial cancer. Data on prognostic factors for patients with early-stage USC without adjuvant therapy are limited. This study aims to assess the baseline recurrence risk of early-stage USC patients without adjuvant treatment and to identify prognostic factors and patients who need adjuvant therapy. METHODS: Sixty-eight patients with International Federation of Gynecology and Obstetrics (FIGO) stage I–II USC between 1997 and 2016 were included. All the cases did not undergo adjuvant treatment as institutional practice. Clinicopathological features, recurrence patterns, and survival outcomes were analyzed to determine prognostic factors. RESULTS: FIGO stages IA, IB, and II were observed in 42, 7, and 19 cases, respectively. Median follow-up time was 60 months. Five-year disease-free survival (DFS) and overall survival (OS) rates for all cases were 73.9% and 78.0%, respectively. On multivariate analysis, cervical stromal involvement and positive pelvic cytology were significant predictors of DFS and OS, and ≥1/2 myometrial invasion was also a significant predictor of OS. Of 68 patients, 38 patients had no cervical stromal invasion or positive pelvic cytology and showed 88.8% 5-year DFS and 93.6% 5-year OS. CONCLUSION: Cervical stromal invasion and positive pelvic cytology are prognostic factors for stage I–II USC. Patients with stage IA or IB USC showing negative pelvic cytology may have an extremely favorable prognosis and need not receive any adjuvant therapies.

Effects of Pharmacist-led Narcotics Management in the Operating Room / 日本農村医学会雑誌

　　Since February, 2012, Anjo Kosei Hospital has embarked upon a new scheme for efficiently handling narcotics during surgical operations. For the purpose pharmacists are allowed to enter the operating room for a while. At the same time, the implementation of digital record keeping for narcotics management tasks has started, making it possible to simplify the handling of a great number of patients. By reviewing the effects on narcotics handling and hours billed, we could determine the effectiveness of operating room pharmacist-led narcotics management at Anjo Kosei. Out of narcotics prescriptions (n＝647) handled in the operating room for one month, 84.7% (548/647) was accounted for by prepared narcotics and 99.8% (646/647) by post-operation management. The introduction of the digital record system resulted in a reduction from 53.3±9.6 minutes to 39.6±6.3 minutes for narcotics preparation, and a reduction from 66.8±16.1 minutes to 41.1±13.5 minutes for post-operation management (p<0.01). It has added to the work efficiency and simplification of operations. Moreover, due to the intervention of pharmacists in the operating room, 92.3% of narcotics prescriptions was performed using the new management system within a relatively short time (80.8±18.4minutes). These data show that the introduction of the new scheme has resulted in more efficient management of narcotics at Anjo Kosei.

Study on Effective and Safe Cancer Chemotherapy for Outpatients (Part1): Influence of Establishment of the Outpatient Cancer Chemotherapy Unit on Effective Usage of Hospital Beds / 日本農村医学会雑誌

Although the Outpatient Cancer Chemotherapy (OCC) Unit was established with in Anjo-Kosei Hospital in 2006, its real worth remains to be elucidated. To address this, the following subjects were examined;effective usage of hospital beds changes in the number of outpatients given to chemotherapy, length of hospitalization, the number of patients transferred by ambulance to the hospital, hospital occupancy rate, and the number of frequently used chemotherapy regimens.Since the establishment of the OCC Unit, the number of patients transferred by ambulance has increased and length of hospitalization has gradually decreased, accompanied by the increase in the number of outpatients treated at the OCC Unit. Additionally, no significant change was observed in the hospital occupancy rate. Furthermore, of the frequently used chemotherapy regimens, nine regimens were available for 62.4% of the total number of outpatients of the OCC Unit.These results indicated the useful effect of the establishment of the OCC Unit on the usage of hospital beds, and provided significant information helpful in promoting the effective and safe chemotherapy for outpatients in the OCC Unit.

Introduction of Problem-Based Preclerkship Clinical Training in Internal Medicine / 医学教育

To increase the safety and effectiveness of clinical clerkships, we have developed a 4-week preclinical training program, “Problem-Based Clinical Training, ” based on the concept of problem-based learning with the aim of encouraging life-long self-directed learning. The first week is a preparation period for clinical practice in which students are trained in problem-solving skills, basic-practice skills, and clinical reasoning. The second and third weeks are a practical training period in which students learn how be in charge of a patient's care. The fourth week was a problem-solving period without practical training in which students learned to solve problems. The students were encouraged to record daily “problem notes” describing problems and “problem solving notes” summarizing problems solved. To emphasize lessons learned, the students also presented and discussed problems. Evidence-based medicine was used as a tool for problem solving. Furthermore, medical record training based on the problem-oriented system using evaluations by other students encouraged self-development to improve clinical practice and the medical record. This curriculum should be effective for mastering the skills of self-directed learning and for motivating for advancement due to consideration of contributable proposals for the patients.

Influence of mouthguards to speech intelligibility / 体力科学

This study was carried out to examine the influence of mouthguards on speech intelligibility. Nine male rugby football players with normal personal occlusion and normal speech served as subjects. All players took the speech intelligibility test while wearing self-adapted mouthguards, custom-made mouthguards and without wearing mouthguards.<BR>The ratio of correct judgments for speech intelligibility wearing self-adapted mouthguards was significantly lower than that of wearing custom-made ones or of not wearing one. When misjudged syllables were evaluated by using the manner of production for articulation, plosives had a tendency to be misjudged as flapped sounds or as other plosives while subjects were wearing self-adapted and custom-made mouthguards. When misjudged syllables were evaluated by the points of production for articulation, bilabials and velars had a tendency to be misjudged as alveolar sounds while subjects were wearing self-adapted and custom-made mouthguards, and alveolar sounds had a tendency to be misjudged as various sounds while subjects were wearing self-adapted ones.<BR>The findings showed that speech intelligibility with custom-made mouthguards was better than with self-adapted ones. Speech intelligibility may be better with mouthguards with reduced palatal thickness than with the current ones because points of prodution for alveolars and velars approach the normal points.

An investigation on the actual conditions of acupuncture school graduates - Their courses, Medical charge and annual income, etc / 全日本鍼灸学会雑誌

A questionnairing was conducted on those who had graduated from acupuncture schools for last three years. 288 questionnaires, that is, 28.8% of the total were answerd.<br>As the result, 41% of the graduates are practicing, 27% are working for institutions connected with acupuncture, and 28% are working in hospitals.<br>Combining present practitioners and those who are to start practice, it seems 76% of the graduates enter practice; most of the graduates aim at setting up practice. Which course to be taken makes the difference in medical charge, the number of patients, and their annual income.
