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.

BACKGROUND/AIMS: This study aimed to examine the diagnostic ability of endoscopic ultrasonography (EUS) for major vascular invasion in pancreatic cancer and to evaluate the relationship between EUS findings and pathological distance. METHODS: In total, 57 consecutive patients who underwent EUS for pancreatic cancer before surgery were retrospectively reviewed. EUS image findings were divided into four types according to the relationship between the tumor and major vessel (types 1 and 2: invasion, types 3 and 4: non-invasion). We also compared the EUS findings and pathologically measured distances between the tumors and evaluated vessels. RESULTS: The sensitivity, specificity, and accuracy of EUS diagnosis for vascular invasion were 89%, 92%, and 91%, respectively, in the veins and 83%, 94%, and 93%, respectively, in the arteries. The pathologically evaluated distances of cases with type 2 EUS findings were significantly shorter than those of cases with type 3 EUS findings in both the major veins (median [interquartile range], 96 [0–742] µm vs. 2,833 [1,076–5,694] µm, p=0.012) and arteries (623 [0–854] µm vs. 3,097 [1,396–6,000] µm, p=0.0061). All cases with a distance of ≥1,000 µm between the tumors and main vessels were correctly diagnosed. CONCLUSIONS: Tumors at a distance ≥1,000 µm from the main vessels were correctly diagnosed by EUS.

OBJECTIVE: To assess the use of colony-stimulating factors (CSFs) in patients with ovarian cancer who receive adjuvant paclitaxel and carboplatin chemotherapy in clinical practice and to assess whether the frequency of CSF use differs among hospitals in Japan. METHODS: CSF use in patients with ovarian cancer who received first-line paclitaxel and carboplatin was analyzed retrospectively using data from the Japanese hospitalization payment system. RESULTS: A total of 1,050 patients at 104 hospitals were identified. The median age was 60 years (range, 22 to 88 years). Of these, 163 patients (15.5%) were diagnosed with neutropenia and 134 patients (12.8%) received CSFs. Among the patients who received CSFs, 125 (93%) received them for the treatment of neutropenia without fever and 1 received them for febrile neutropenia. In total, CSFs were administered for 272 cycles of chemotherapy. Among them, CSFs were used as treatment for neutropenia without fever in 259 cycles (95%), as prophylaxis (primary or secondary) in 12 cycles (4%), and as treatment for febrile neutropenia in 1 cycle. Among hospitals, a median of 4.0% of patients received CSFs with an interquartile range of 25% (Q1, 0%; Q3, 25%). A logistic random effects model showed that the variation in the proportion of patients receiving CSFs among the 104 hospitals was 2.0 (p<0.001), suggesting that the use of CSFs varied across hospitals. CONCLUSION: Most patients received CSFs for neutropenia without fever. Standardized and evidence-based use of CSFs is critically required among hospitals in Japan.

The incidence of wound infection and delayed wound healing was greater in neonates and infants less than 3 months old who had undergone open heart surgery through a median sternotomy than in older patients. To reduce these problems, we stopped using continuous absorbable braided suture for skin and subcutaneous tissue closure in August 2005, and used interrupted non-absorbable monofilament suture instead. Around the same time, we adopted hydrocolloid dressing as a substitute for gauze dressing. We evaluated the effectiveness of wound management by comparing 28 patients who had undergone surgery before August 2005 with 22 patients who underwent surgery after that date. The age at surgery was 45±30 and 21±23 days, respectively. The patients in the earlier period were significantly older than in the later period. There were no significant differences in body weight at surgery, operating time, or cardiopulmonary bypass time between the groups. The time for wound closure was 30±11 and 22±4 min, respectively, and the patients were hospitalized after surgery for 61±41 and 44±31 days. Both were significantly shorter in the later group of patients. There was a single case of mediastinitis, in the earlier period. Wound infection or delayed wound healing occurred in 8 patients in the earlier period and in 3 patients in the later period. The only 4 patients who required wound resuturing were all in the earlier period. The incidence of wound infection and delayed wound healing tended to be low in the later period. We believe that interrupted non-absorbable monofilament sutures improved the wound microcirculation and that the hydrocolloid dressing accelerated wound healing via its moisturizing and heat-retention action, pH buffering ability, and bacteriostatic activity, and that all these contributed to the better outcomes in the later period.

A 47-year-old man had suffered from high grade fever and dyspnea for 10 days. He was transferred to our hospital in a condition of shock. Echocardiography showed severe diffuse hypokinesis of left ventricle (EF 21%), and multiple mobile thrombi in the left ventricle. Under a diagnosis of LV thrombi due to acute myocarditis, transatrial removal of LV thrombi was performed using video-assisted cardioscopy. He was weaned from cardiopulmonary bypass under IABP support. Postoperatively, he suffered from thromboembolism of the cerebral and right brachial artery. Thrombectomy of the right brachial artery and anticoagulation therapy was performed. IABP was removed on POD 3, and he no longer needed respiratory control on POD 4. Echocardiography on POD 6 showed marked improvement of the LV contraction (EF 52%). After rehabilitation, he was discharged on POD 23 on foot. Video-assisted cardioscopy allowed transatrial removal of LV thrombi, and preserved left ventricular function by avoiding ventriculotomy. Perioperative thromboembolism must be taken care of for a patient with multiple LV thrombi.

A 27-year-old woman was given a diagnosis of infectious endocarditis with severe tricuspid regurgitation. Despite adequate antibiotics therapy, her general condition did not improve, and moreover multiple pulmonary abscesses were detected by computed tomography. Therefore surgery was indicated. Surgery consisted of removal of vegetation and tricuspid valve plasty with autologous pericardial patch augmentation of the anterior leaflet. Tricuspid valve plasty was carried out without prosthetic materials. Her postoperative course was uneventful with only mild tricuspid regurgitation. One year after surgery, neither recurrence of infection nor worsening of tricuspid regurgitation was noted. This method could be a useful technique for young patients with severe infection.

A 36-year-old previously healthy woman with cardiomegaly on a routine chest X-ray was given a diagnosis of primary chylopericardium after pericardial puncture revealed milky effusion. Endoscopy-assisted ligation of the thoracic duct and creation of a pericardial window was performed. The operation was greatly facilitated by the preoperative three-dimensional CT scan with lymphangiography that precisely demonstrated the distribution of the thoracic duct and other lymphatic ducts.

We report 4 cases of valvular injury following nonpenetrating cardiac trauma in 3 men and 1 woman ranging in age from 24 to 72 years. In all cases the cause of trauma was blunt chest trauma. One patient was operated in 4h, but the other 3 patients were operated on more than 6 months after the accidents. Lacerated aortic cusp was observed in 2 patients, ruptured anterior papillary muscle of mitral valve, and ruptured chordae tendinae of the tricuspid vale were observed in 1 patient each respectively. Three patients underwent valve replacement (2 aortic and 1 mitral valves), and another patient underwent chordoplasty in the tricuspid valve. Their post-operative courses were uneventful. Careful observation, such as echocardiography, were required following the blunt chest trauma.

A 16-year-old boy with multiple injuries suffered in a motorcycle accident was admitted to our hospital. On admission, X-ray films showed left hemothorax and bone fractures of the left humerus, thigh bone, and pelvis. Computed tomography of the chest revealed a pseudoaortic aneurysm approximately 6.0cm in diameter at the proximal portion of the descending aorta. Because of multiple severe associated injuries, we considered that conventional aortic repair in the acute phase would be difficult. We therefore performed an endovascular stent-graft treatment 140 days after injury. The postoperative course was uneventful and the pseudoaneurismal sac has confirmed to decrease. Transluminal placement of endovascular stent-graft is a technically feasible method for treatment of traumatic aortic aneurysm. However, because the long-term results are still unknown, we should follow-up carefully, particularly in young patients.

A 50-year-old man was admitted with a fusiform descending thoracic aortic aneurysm measuring 60mm. Chest CT scan revealed porcelain aorta from the aortic arch to the abdominal aorta. Severe calcification found on the descending aortic wall was considered to entail greater risk for conventional aortic repair and reconstruction of intercostal arteries. Therefore endovascular stent grafting was planned. The stent graft was deployed from near the origin of the left subclavian artery to the 10th thoracic vertebral level. Neither paraplegia nor other complication occurred. Endovascular stent grafting may be a safe and effective method for descending thoracic aneurysms with severely calcified aorta.
