Objective：There are few reports on decision-making support at palliative care clinics in designated regional cancer care hospitals. This study clarified the types of decisionmaking support patients with cancer and their families were provided by specialized outpatient palliative care services. Method：We retrospectively examined the medical records of 110 patients who had been referred to the palliative care clinic for home care between April 2012 and March 2014. Results：The median duration of receiving services from the palliative care clinic was 23 days（range：1～492 days）. The mean number of visits to the clinic was 4.7 visits（range：1～29 visits）. A total of 89 patients（80％）needed decision-making support. Of those 89 patients, 33（30％）required support in making a decision about anticancer treatment. Twenty-six（78％）of those 33 patients had just received the diagnosis or were receiving anticancer treatment. Conclusion：The study suggested that decision-making support in early stages is an important role for a palliative care clinic in a designated regional cancer care hospital.

To avoid homologous blood transfusion, the effectiveness of autologous blood predonation was evaluated in patients with elective abdominal aortic aneurysm (AAA) repair. From January 1993 to July 1996, 53 patients underwent Y graft replacement by using autologous rapid transfusion device AT1000^® (Electromedics. Inc, Englewood, CO). The patients were devided in to 3 groups. Thirty one patients had no blood donation (Group A). Twelve patients had 400ml blood donation with administration of an iron preparation (Group B). Ten patients donated the same amount of blood as those in Group B, with administration of both an iron preparation and recombinant human erythropoietin (rHuEPO) (Group C). There were no significant differences in terms of age, gender, operating time, intraoperative bleeding, and total amount of homologous and autologous blood transfusion in the 3 groups. In Group A, the mean volume of homologous blood transfusion was 250±370ml and in both Groups B and C, no homologous blood was required and 400ml autologous blood was used. Homologous blood transfusion was avoided in 58.9 (18/31) of patients in Group A and all of the patients in Groups B and C. Due to the blood predonation prior to surgery, a hemoglobin level decreased significantly at the time of operation in Group B (without rHuEPO), but in Group C (with rHuEPO) the hemoglobin level was kept constant. During the first postoperative week, the minimum hemoglobin level in Group C was significantly higher than in the other groups. In conclusion, by donating 400ml autologous blood before surgery and using an intraoperative autotransfusion system, homologous blood transfusion could be avoided in elective AAA repair. With rHuEPO, the hemoglobin level could be maintained, despite predonation and intraoperative blood loss.

Primary malignant cardiac tumors are extremely rare. Among these, leiomyosarcoma are particularly exceptional and only about 20 surgically treated cases have been extensively described. We describe a case of right atrial leiomyosarcoma which was accidentally found by computed tomography. The tumor was surgically resected under extracorporeal circulation. Two months later the patient had cerebral hemorrhage due to a brain metastasis, which almost completely disappeared after irradiation. There was no other evidence of recurrence for 12 months after operation.

Uterine leiomyosarcoma (ULMS) is one of the most aggressive gynecological malignancies. In the past decade, novel therapeutic agents such as trabectedin and pazopanib have been approved, but the prognosis of patients remains unsatisfactory. This study aimed to identify potential therapeutic targets for ULMS based on transcriptome analysis. Archival fresh-frozen tumor tissues of 6 ULMS and three leiomyoma samples were used in this study, and total RNA was extracted. First, transcriptome analysis identified 512 significantly differentially expressed genes, and subsequent pathway analysis using IPA software revealed that the functions of cell cycle-related kinases were significantly activated in ULMS. Moreover, our results were validated using 3 independent Gene Expression Omnibus datasets, including 40 ULMS. Therefore, we considered the kinases as novel therapeutic targets and evaluated the anti-cancer effects of several selective inhibitors against them. Most inhibitors exerted a higher anti-cancer effect than pazopanib in three leiomyosarcoma cell lines. Especially, CHEK1 or PLK1 inhibitors strongly induced cell cycle arrest and cell death, and the IC50s were lower nanomolar concentration. Moreover, the inhibitors suppressed the tumor growth in SK-UT-1 bearing mice models. In conclusion, we revealed the unique gene expression profiles of ULMS. CHEK1 and PLK1 are promising therapeutic targets for ULMS, and therefore, further clinical trials are highly anticipated to improve the prognosis of the patients.

Mandibular chronic osteomyelitis with diffuse osteosclerosis is recognized as an intractable infectious disease. We emplyed decortication and intra-arterial infusion of antibiotics in 6 cases. Decortication on the affected mandible was performed with retrocatherization to the superficial temporal artery of affected side under general anesthesia. Antibiotics, IPM/CS or FOMX was used through the artery for 4-11 days. In addition, we administered FOMX, PIPC intravenously for 8-17 days. CT and MRI were taken postoperatively. The postoperative follow-up period ranged from 1 year and 6 months to 2 years and 5 months. Postoperative MR showed that bone marrow signal was recovered to approximately normal in 4 cases. High signal area of bone marrow and osteosclerosis image remained in 2 cases, but showed improvement. The results were satisfactory without recurrence in all of 6 cases.

STUDY DESIGN: Retrospective case series. PURPOSE: To evaluate surgical outcomes and effectiveness of an autogenic rib graft for upper cervical fixation in pediatric patients. OVERVIEW OF LITERATURE: Autogenic bone grafts have long been considered the ‘gold standard’ bone source for posterior cervical fusion in pediatric patients. However, there are some unsolved problems associated with donor-site morbidity and amount of bone grafting. METHODS: We studied five consecutive pediatric patients who underwent atlantoaxial fixation or occipitocervical fixation (OCF) using an autogenic rib graft with at least 2 years of follow-up (mean age, 9.8 years; mean follow-up period, 73.0 months). Two patients underwent OCF without screw-rod constructs and three patients with screw-rod constructs. Autogenic rib grafts were used in all patients. We evaluated the surgical outcomes including radiographic parameter, bony union, and perioperative complications. RESULTS: The atlantoaxial interval (ADI) was corrected from 11.6 to 6.0 mm, and the C1–2 angle was corrected −14.8° to 7.8°. The C2–7 angle was reduced from 31° to 9° spontaneously. Two patients with OCF required revision surgery due to loss of correction. Patients did not experience any complication associated with the donor sites (rib bone grafts). Six months postoperation X-rays clearly showed regeneration of the rib at the donor sites. Bony fusion was achieved in all patients; however, bony fusion occurred more slowly in patients without screw-rod constructs compared with patients with screw-rod constructs. Bone regeneration of the rib was observed in all patients with no complications at the donor site. CONCLUSIONS: Autogenic rib grafts have advantages of potential bone regeneration, high fusion rate, and low donor-site morbidity. In addition, a screw-rod construct provides better bony fusion in pediatric patients with OCF and atlantoaxial fixation.

Objective: Ovarian clear cell carcinoma (OCCC) is a subtype of epithelial ovarian carcinoma with poor prognosis. However, no effective biomarkers have been established for predicting unfavorable events, including recurrence and poor prognoses. Serum microRNAs (miRNAs) have been increasingly reported to be useful in predicting a patient’s condition and have been recognized as a potentially less-invasive source for liquid biopsy in cancer. Therefore, this study aimed to evaluate serum miRNA profiles from patients with OCCC and to establish biomarker for predicting the prognoses. Methods: The GSE106817, which included preoperative serum miRNA profiles of patients with ovarian tumors, was used, and clinical information was investigated. In all, 66 patients with OCCC were included, excluding those with other histological subtypes or insufficient prognostic information. Moreover, miRNA profiles of OCCC tissues were also examined. Results: The median follow-up period was 64.3 (8.0–153.3) months. Based on multivariable Cox regression analyses and the expression of miRNAs in OCCC tissues, miR-150-3p, miR-3195, and miR-7704 were selected as miRNA candidates associated with both progression-free survival (PFS) and overall survival (OS). Then, the prognostic index was calculated based on expression values of 3 serum miRNAs. Kaplan-Meier survival analysis indicated that the prognostic index was significantly predictive of PFS and OS (p=0.004 and p=0.012, respectively). Conclusion Preoperative serum miRNA profiles of miR-150-3p, miR-3195, and miR-7704 can be used to potentially predict the prognosis of patients with OCCC.

Objective: To apply the International Federation of Gynecology and Obstetrics (FIGO) 2018 staging system to all patients who underwent trachelectomy in our previous study and to update the oncologic and obstetric results. Methods: We retrospectively reviewed the medical records of patients in whom abdominal trachelectomy was attempted between June 2005 and September 2021. The FIGO 2018 staging system for cervical cancer was applied to all patients. Results: Abdominal trachelectomy was attempted for 265 patients. Trachelectomy was converted to hysterectomy in 35 patients, and trachelectomy was completed successfully in 230 (conversion rate: 13%). Applying the FIGO 2018 staging system, 40% of the patients who underwent radical trachelectomy had stage IA tumors. Among 71 patients who had tumors measuring ≥2 cm, 8 patients were classified as stage IA1 and 14 as stage IA2. Overall recurrence and mortality rates were 2.2% and 1.3%, respectively. One hundred twelve patients attempted to conceive after trachelectomy; 69 pregnancies were achieved in 46 patients (pregnancy rate: 41%). Twenty-three pregnancies ended in first-trimester miscarriage, and 41 infants were delivered between gestational weeks 23 and 37; 16 were deliveries at term (39%) and 25 were premature deliveries (61%). Conclusion This study suggested that patients judged to be ineligible for trachelectomy and patients receiving overtreatment will continue to appear using the current standard eligibility criteria. With the revisions to the FIGO 2018 staging system, the preoperative eligibility criteria for trachelectomy, which were based on the FIGO 2009 staging system and tumor size, should be changed.

Methods: We retrospectively reviewed 31 ASD patients who underwent multilevel LIF combined with PCO (LIF group, n=14) or multilevel PLIF (PLIF group, n=17) and with a minimum 2-year follow-up. In the comparison between LIF and PLIF groups, their mean age at surgery was 69.4 vs. 61.8 years while the mean follow-up period was 29.2 vs. 59.3 months. We evaluated the transition of pelvic incidence–lumbar lordosis (PI–LL) and disc angle (DA) in the LIF group, in fulcrum backward bending (FBB), after LIF and after posterior spinal fusion (PSF) with PCO. The spinopelvic radiographic parameters were compared between LIF and PLIF groups. Results: Compared with the PLIF group, the LIF group had less blood loss and comparable surgical outcomes with respect to radiographic data, health-related quality of life scores and surgical time. In the LIF group, the mean DA and PI–LL were unchanged after LIF (DA, 5.8°; PI–LL, 15°) compared with the values using FBB (DA, 4.3°; PI–LL, 15°) and improved significantly after PSF with PCO (DA, 8.1°; PI–LL, 0°). Conclusions In the surgical treatment of ASD, multilevel LIF is less invasive than multilevel PLIF and combination of LIF and PCO would be necessary for optimal sagittal correction in patients with rigid deformity.
