Since 2000 we have used a home-visit nursing program for fifth-year medical students at Gifu University to examine the significance of domiciliary and geriatric medicine. We used questionnaires before and after the program to evaluate its effects on students. The desire of students to be involved with both domiciliary and geriatric medicine as phys iciansincreased after the program. Greater increases were observed among students who knew less before the program about the significance of home and elder care. The program was effective for encouraging medical students to think about domiciliary and geriatric medicine.

Reports laparoscopic deroofing of liver cysts have drawn our attention recently. A laparoscopic approach has advantages as minimal access surgery, but has the possibility of causing complications by hemorrhage and bile leakage. In this paper, we described three surgical cases of symptomatic giant liver cysts. In case 1, hemorrhage occurred when we resected the cyst wall by electrocautery with the aid of a laparoscope. Therefore, in case 2, we resected the cyst wall with an endoscopic stapling device (ENDO GIA) for complete hemostasis and control of bile duct, because the peritoneal surface of the cyst was overlaid by thin parenchymal tissue. In case 3, we resected the cyst wall with laparoscopic coagulating shears (LCS), because the peritoneal surface of the cyst was mainly extrahepatic. This device reduces the risk of hemorrhage and damage to the liver. These patients were asymptomatic after operation and developed no signs of recurrence. We suggest that the laparoscopic deroofing of liver cysts with these devices, a simple, safe procedure, may become a primary method of treating symptomatic liver cysts.

A total of 82 cases of breast cancer detected by hand-scanning ultrasound massscreenig (hereafter referred to as US screening) over the past 15 years were divided into two groups--one aged under 50 and the other aged 50 or over at the time of examinaton. The accuracy and capacity of US screening and the rate of patients with subjective symptoms were studied for each group. As a result, we discovered that the groupaged under 50 was significantly higher in the rate of “further examination needed”, and the rate of “having subjective symptoms”, and was significantly lower in “positive predictivevalue” than the older age group. In the detection rate, sensitivity and specificity, there was no difference between the two groups. Thus, we concluded that US screening were beneficial to both groups.
Dividing the 15 years of US screening into three periods (each 5 years), we investigated the caliber of detected breast cancers, and found the tumor size became smaller year after year. As a result, the cases of non-palpable breast cancer came to form 26.6%, of which 72.3% was accounted for by invasive breast cancer. Further more, we found that in the group aged under 50, because of stiffness of their breast gland, the ratio of non-palpable breast cancer came to 30.2%, which was larger than in the older age group, and 69.2% cases out of them were invasive breast cancer. We are afraid that mass-screening by physical examination alone will overlook many cases of breast cancer, and we recommend that in view of the increasing mortality rate of breast cancer in women in their50s the safe and useful US screening program should be implemented without delay on the younger age group.

OBJECTIVE: To treat advanced ovarian cancer, interval debulking surgery (IDS) is performed after 3 cycles each of neoadjuvant chemotherapy (NAC) and postoperative chemotherapy (IDS group). If we expect that complete resection cannot be achieved by IDS, debulking surgery is performed after administering additional 3 cycles of chemotherapy without postoperative chemotherapy (Add-C group). We evaluated the survival outcomes of the Add-C group and determined their serum cancer antigen 125 (CA125) levels to predict complete surgery. METHODS: A retrospective chart review of all stage III and IV ovarian, fallopian tube, and peritoneal cancer patients treated with NAC in 2007–2016 was conducted. RESULTS: About 117 patients comprised the IDS group and 26 comprised the Add-C group. Univariate and multivariate analyses revealed that Add-C group had an equivalent effect on progression-free survival (PFS; p=0.09) and overall survival (OS; p=0.94) compared with the IDS group. Multivariate analysis revealed that patients who developed residual disease after surgery had worse PFS (hazard ratio [HR]=2.18; 95% confidence interval [CI]=1.45–3.28) and OS (HR=2.33; 95% CI=1.43–3.79), and those who received <6 cycles of chemotherapy had worse PFS (HR=5.30; 95% CI=2.56–10.99) and OS (HR=3.05; 95% CI=1.46–6.38). The preoperative serum CA125 cutoff level was 30 U/mL based on Youden index method. CONCLUSIONS: Administering 3 additional cycles of chemotherapy followed by debulking surgery exhibited equivalent effects on survival as IDS followed by 3 cycles of postoperative chemotherapy. Preoperative serum CA125 levels of ≤30 U/mL may be a useful predictor of achieving complete surgery.

Objective:
This study aimed to investigate the prognosis of patients with intermediate-risk cervical cancer and to evaluate the necessity of adjuvant therapy.
Methods:
We conducted a retrospective chart review of patients with stage IB–II cervical cancer who underwent type III radical hysterectomy with pelvic lymphadenectomy between 2008 and 2017. In our institution, radical hysterectomy is performed as an open surgery and not as a minimally invasive surgery, and adjuvant therapy is not administered to patients with intermediate-risk cervical cancer. The intermediate-risk group included patients with 2 or more of the following factors: tumor size >4 cm, stromal invasion >1/2, and lymphovascular stromal invasion. Intermediaterisk patients with squamous cell carcinoma were included in the I-SCC group, whereas those with endocervical adenocarcinoma, usual type, or adenosquamous carcinoma were included in the I-Adeno group.
Results:
There were 34 and 18 patients in the I-SCC and I-Adeno groups, respectively. The 5-year recurrence-free survival (RFS) and overall survival rates in the I-SCC group were 90.5% (95% confidence interval [CI], 85.3–95.7%) and 100% (95% CI, 100%), respectively, whereas those in the I-Adeno group were 54.9% (95% CI, 42.0–67.9%) and 76.1% (95% CI, 63.7–88.4%), respectively. Multivariate analysis revealed that endocervical adenocarcinoma, usual type, or adenosquamous carcinoma, and tumor size >4 cm had worse RFS.
Conclusion
The I-SCC group had good prognosis without adjuvant therapy; therefore, adjuvant therapy may be omitted in these patients. In contrast, the I-Adeno group had poor prognosis without adjuvant therapy; therefore, adjuvant therapy should be considered in their treatment.

We report a successful conversion of anti-coagulant therapy from warfarin to heparin for a case of mechanical heart valve and warfarin-induced skin ulcer. A 57-year-old female who was diagnosed with Ebstein disease and underwent mechanical valve replacement suffered from a recurring and resistant leg skin ulcer. Nine years after the induction of warfarin, her right leg skin ulcer occurred suddenly and worsened gradually. No dermatological treatment could cure it and three auto-skin transplantations were performed in the past four years. The definitive cause of the ulcer could not be diagnosed by any laboratory study or image inspection. Further, after every transplant surgery, the resumption of warfarin had made her ulcer recur and worsen. Therefore, we finally came to think of this disease as the warfarin-induced skin ulcer. To avoid warfarin, subcutaneous self-injection therapy of Heparin-Ca was applied as her anti-coagulation after the 4th transplant surgery. The patient was discharged from hospital on post-operative day 78 with a good condition of the transplanted skin graft and right leg. An adequate level of APTT could be maintained with injections of 10,000 units of Heparin-Ca twice a day and data on D Dimer and cardiac echography show no thromboembolism at the out-patient visits. The result of auto-skin transplantation is also a good course under this therapy. As we have very few reports concerning heparin self-injection therapy for artificial valves, it is very important that careful observation should be continued.

Objective:
The purposes of this trial were to demonstrate the feasibility and effectiveness of the hybrid of intracavitary and interstitial brachytherapy (HBT) for locally advanced cervical cancer patients in the phase I/II prospective clinical trial.
Methods:
Patients with FIGO stage IB2-IVA uterine cervical cancer pretreatment width of which was ≥5 cm measured by magnetic resonance imaging were eligible for this clinical trial. The protocol therapy included 30–30.6 Gy in 15–17 fractions of whole pelvic radiotherapy concurrent with weekly CDDP, followed by 24 Gy in 4 fractions of HBT and pelvic radiotherapy with a central shield up to 50–50.4 Gy in 25–28 fractions. The primary endpoint of phase II part was 2-year pelvic progression-free survival (PPFS) rate higher than historical control of 64%.
Results:
Between October 2015 and October 2019, 73 patients were enrolled in the initial registration and 52 patients proceeded to the secondary registration. With the median follow-up period of 37.3 months (range, 13.9–52.9 months), the 2- PPFS was 80.7% (90% confidence interval [CI]=69.7%–88%). Because the lower range of 90% CI of 2-year PPFS was 69.7%, which was higher than the historical control ICBT data of 64%, therefore, the primary endpoint of this study was met.
Conclusion
The effectiveness of HBT were demonstrated by a prospective clinical study. Because the dose goal determined in the protocol was lower than 85 Gy, there is room in improvement for local control. A higher dose might have been needed for tumors with poor responses.
