Abstract
BACKGROUND/AIM Most cases of synovial sarcoma (SS) are aggressive and large-sized; only few show indolent behavior, having a small size. Nerves are rare sites of SS occurrence. An atypical case of SS can lead to its misdiagnosis as a benign tumor and delay its treatment. CASE REPORT Here, we report a case of primary SS of indolent multinodular synovial sarcoma of peripheral nerves. Considering the clinical and imaging findings at the first visit, we suspected a benign tumor and continued careful follow-up. Three years later, marginal resection was performed and SS was suspected. We then performed an additional wide resection using a free flap. Histopathologically, the proximal tumor showed a diffuse proliferation of spindle cells without pleomorphism, whereas the distal tumor showed a similar histology with more hypercellularity. Additional wide-resection specimens showed remnant tumors derived from the peripheral nerve. Immunohistochemistry (IHC) showed positive staining for SS18:SSX and SSX in both tumors and fluorescence in situ hybridization showed positive staining for the SS18 split in both tumors. Finally, SS of the peripheral nerve was diagnosed. Owing to FNCLCC grade 2 tumor and tumor size, adjuvant chemotherapy was not performed. CONCLUSION In cases of SS or other sarcomas with atypical clinical courses, with imaging findings mimicking benign tumors, we recommend marginal resection along with pathological examination for correct diagnosis.

Abstract
OBJECTIVES Delirium, a neurocognitive disorder, typically occurs in older patients and those with advanced cancer. Although there have been numerous reports on delirium in patients with cancer in various conditions, there are no reports that specifically focus on patients with musculoskeletal tumours. This prospective study aimed to investigate the incidence, risk factors and prognostic implications of delirium in patients with musculoskeletal tumours. METHODS In this single institutional study, 148 patients with musculoskeletal oncology were enrolled. The estimated risk factors included age, sex, alcohol abuse, performance status (PS), dietary status, admission route, tumour malignancy, oncological stage and blood test results. The significance of delirium in survival was also examined. RESULTS Only 18 patients with malignant tumours had delirium (12.2%). Based on univariate analysis, older age, poor PS, dietary status, admission from another hospital, malignant tumour, carcinoma rather than sarcoma, anaemia and some laboratory abnormalities were found to be significant risk factors for delirium. Multivariate analysis showed that poor PS was significantly correlated with delirium. Additionally, delirium was significantly correlated with poor survival. CONCLUSIONS The incidence of delirium among patients with musculoskeletal tumours was 12.2% and was observed only in patients with malignant tumours. PS is a significant risk factor for delirium. Delirium is correlated with poor prognosis.

Abstract
BACKGROUND BCOR CCNB3 sarcoma is a rare mesenchymal tumor that was formerly included in the undifferentiated/unclassified sarcoma group and was recently reclassified as one of undifferentiated small round cell sarcomas with a genetically distinct subtype in the WHO 2020 classification. Because of its rarity, still not much is known, especially about its clinical features. CASE REPORT A 15-year-old boy presented with almost 1-year intermittent thigh pain. On the first visit, a pathologic fracture of the femur and a big mass expanding through the femoral cortex with lobular shape and homogenous appearance were recognized on radiography and magnetic resonance imaging. Plain radiography, which was taken 6 months before at a local clinic, showed an expansion and thickening of the right proximal femoral shaft. Biopsy specimen of the lesion revealed a proliferation of round to spindle tumor cells with diffuse and strong immunohistochemical nuclear positivity for BCOR and CCNB3. Under the diagnosis of BCOR::CCNB3 sarcoma of the femur, a chemotherapy based on a protocol of Ewing sarcoma, followed by a wide resection and total femoral replacement surgery, were conducted. The effect of chemotherapy was favorable, showing no microscopic residual tumor. Although postoperative chemotherapy was not completed because of a minor infection detected on the surgical site, the patient was doing well, without any recurrence, for 26 months. CONCLUSIONS BCOR CCNB3 sarcoma of the bone is a quite rare tumor with much lower incidence than Ewing sarcoma. Notable clinical characteristics of the current case were a 1-year-long symptomatic period and homogenous appearance on MRI.

Abstract
Extraskeletal osteosarcoma (EO) is a soft tissue sarcoma characterized by the production of bone matrix by neoplastic cells. Benign osteoid in EO, leading to a diagnostic dilemma, is rarely encountered. Herein, for the first time, we present a case with cytogenetically confirmed EO combined with or preceding myositis ossificans (MO). A 21-year-old man had a mildly painful swelling in his left knee. Imaging studies demonstrated a 39-mm mass with peripheral mineralization and cystic change on the posterolateral side of the left fibular head. He was clinically suspected of having either MO or a malignancy, such that wide resection was performed. Macroscopically, the mass was grayish to brown. In the cut section, multiple cystic lesions in addition to solid components were noted. Histopathologically, the solid components demonstrated diffuse proliferation of pleomorphic tumor cells with osteoclast-like giant cells. The malignant tumor cells formed osteoid. In the periphery, the mass was benign, showing mature bone tissue and focally non-malignant woven bone with fibroblasts, compatible with zonation. Fluorescence in situ hybridization (FISH) demonstrated split signals of the USP6 gene. These findings suggested EO with preceding MO. Although the pathogenesis remains to be elucidated, the observed USP6 rearrangement might contribute to both the diagnosis of EO with preceding MO and an understanding of the underlying histopathology.

Abstract
INTRODUCTION BCOR-CCNB3 sarcoma (BCS) is one of the histological types classified as an undifferentiated small round cell sarcoma of bone and soft tissue. This sarcoma frequently develops in males under 20 years of age. Histologically, a delicate capillary network has been reported as a conspicuous finding. In this study, the cytological findings of BCS were observed in two cases of primary lesions and one case of a lung metastatic lesion. The cytological findings of BCS were compared with its histological mimics, and the characteristic findings of BCS were examined. METHODS Three cases of BCS were studied, and a cytological comparison was performed with 8 cases of Ewing sarcoma (ES) and 10 cases of synovial sarcoma (SS; monophasic type: 7 cases, biphasic type: 2 cases, poorly differentiated: 1 case). RESULTS In all BCS cases, small clusters with thin and delicate vascular cores and tiny vascular fragments were conspicuous. In ES and SS cases, although small clusters with vascular cores were observed, the vascular cores were thicker than in BCS, and no tiny vascular fragments appeared in most cases. Cytomorphological differences of tumour cells were also observed among BCS, ES, and SS. Predominantly rounded nuclei with fine chromatin and inconspicuous nucleoli can be cytological clues for BCS. CONCLUSIONS BCS shows characteristic cytological findings that make the diagnosis of BCS more likely than that of ES and SS. Cytological evaluation is a useful tool for appropriate differential diagnosis that leads to a more accurate final diagnosis and rapid treatment.

Abstract
Aim Patients with skeletal metastasis from prediagnosed primary malignancy sometimes have concurrent oncologic emergency (OE) during the first visit. This study aims to investigate the types of OEs and treatment outcome in such patients. Methods We have experienced 359 patients with skeletal metastasis from unknown primary malignancy. Among them, 130 patients required immediate admission for OE treatment (OE group), 229 patients had no OE and did not required immediate admission (non‐OE group). Results The recognized types of OE were spinal cord compression in 60 patients, cancer pain in 30, hypercalcemia in 19, delirium in 16, deep vein thrombosis in 13, acute renal failure in 6, respiratory failure in 3, gastrointestinal hemorrhage in 3, and disseminated intravascular coagulation in 1. The overall 5‐year survival rates were 28% and 37% in the OE and non‐OE groups, respectively (P < 0.001). The multivariate analysis revealed that delirium (hazard ratio 4.2; 95% confidence interval, 1.6–12.5; P < 0.005) and respiratory failure (hazard ratio 22.6; 95% confidence interval, 4.5–92.8; P < 0.001) were significant prognostic factors in patients with OEs, whereas other OEs did not confer a significant risk for patient outcomes. Conclusion In this study, OE was observed in as many as 36% of patients with skeletal metastasis from unknown primary malignancy. Delirium and respiratory failure were only two significant prognostic risk factors, which suggest that many of the OEs in untreated advanced cancer patients have probable chance to resolve. Early detection followed by appropriate treatment of such OEs is recommended.

Abstract
Background Prosthetic reconstruction for distal femoral osteosarcoma is challenging for younger children. We herein report a successful case of limb-sparing surgery for a younger patient with distal femoral osteosarcoma requiring osteo-articular resection. Case presentation A 5-year-old girl with high-grade conventional osteosarcoma in the left distal femur underwent a series of surgeries. After three cycles of neoadjuvant chemotherapy, limb-salvage surgery was planned because femoral rotationplasty had been refused. At 6 years and 2 months old, distal femoral resection and temporary spacer insertion using a 7-mm-diameter intramedullary nail and molded polymethylmethacrylate was performed. At 7 years and 8 months old, secondary surgery was performed because the first spacer had been dislocated and the residual femur became atrophic. The distal end of the residual femur was removed by 1 cm, but the periosteum and induced membrane around polymethylmethacrylate was preserved. In order to stabilize the spacer against the tibia, a custom-made ceramic spacer with a smooth straight 8-mm-diameter stem was utilized. The bone-spacer junction was fixed with polymethylmethacrylate and then covered with the preserved periosteum and induced membrane. After surgery, the bone atrophy improved. At 9 years and 7 months old, the second spacer was removed because it had loosened, and the knee joint was reconstructed using a custom-made growing femoral prosthesis with a curved porous 8.5-mm-diameter stem. Cancellous bone tips from the proximal tibia were grafted around the bone-prosthesis junction underneath the induced membrane. At 10 years and 5 months old, the patient was able to walk unsupported and a radiograph showed further thickening of the cortex of the residual femur without any stress shielding. Although having 5 cm of limb length discrepancy, the patient and her mother were satisfied with the function. The MSTS score was 24 out of 30 points. Repeated limb length extensions are planned. Conclusions This case report provides an example of limb-salvage surgery after distal femoral resection in a small child. The use of a temporary spacer utilizing partial cementation and preservation of the periosteum and induced membrane appears to afford a viable limb-salvage option after distal femoral resection for younger children.

Abstract
We reported the first case to use navigation for the femoral head chondroblastoma. Visualization of tumor on navigation helps to minimize unnecessary destruction. Navigation assistance is an optimal surgical option for chondroblastoma in the femoral head.
Introduction Surgery for chondroblastoma in the femoral head is challenging due to its inaccessibility, with high risk of local recurrence and poor functional outcomes reported. We herein report the first case of chondroblastoma in the femoral head treated by navigation-assisted surgery. Presentation of case A 12-year-old girl presented with persistent left hip pain and limited hip range of motion. Imaging studies revealed a well-defined osteolytic lesion in the left femoral head accompanied by extensive intra-osseous oedematous change. The bone lesion was radiologically diagnosed as chondroblastoma. With navigation assistance, curettage was performed via the anterior approach. The tumor was fully accessible from the femoral neck. After curettage, the bony defect was filled with bone substitute. The pathological diagnosis was chondroblastoma. The post-operative course was uneventful. Thirty months postoperatively, the patient was free of pain with full hip range of motion, and MR images showed no evidence of recurrence or osteonecrosis. Discussion This case is the first to use a navigation system for the treatment of chondroblastoma in the femoral head. The navigation system can minimize damage to intact structures and increase the efficiency of curettage by visualizing access to the tumor. Conclusion Navigation assistance is an optimal surgical option for chondroblastoma in the femoral head.

Abstract
BACKGROUND It is unclear whether antecedent primary malignancies (APMs) have any negative impact on the prognosis of soft tissue sarcoma (STS). We retrospectively reviewed STS patients with APMs (STS-APM) and compared their survival to those of STS only (STS-O). METHODS Twenty-one cases of STS-APM from 2008 to 2017 in our institution were analyzed. One hundred and seventy cases of STS-O at the same period were compared as a control group. Overall survival was estimated using Kaplan-Meier survival curves and prognostic factors were analyzed using logistic regression analyses and contingency table analyses. RESULTS As the final status of STS-APM patients, 12 patients were in disease-free survival, 5 were alive with disease, 3 have died of disease, and 1 has died of another disease. There was no case that died of APM. The 5-year overall survival rates were 88% in STS-APM and 78% in STS-O, showing no statistical significant ( p = 0.65). The 5-year overall survival rates in each stage of STS-APM and STS-O were 100/100% in stage I, 100/85% in stage II, 86/72% in stage III, and the 3-year overall survival rates were 67/51% in stage IV, with no statistical significance. With regard to prognostic factor, histological grade of STS was the only significant factor. Although antecedent radiotherapy tended to show a high odds ratio, the association was not statistically significant. Antecedent chemotherapy did not show any estimated prognostic risk. CONCLUSIONS Our study suggested that APM in STS patient would not be a negative prognostic factor.

Abstract
Histiocytic sarcoma (HS) is a rare hematopoietic tumor that mainly involves extranodal sites, including the intestinal tract, skin, soft tissues and other organs. It is well known as an aggressive neoplasm that shows a poor response to therapy. However, a subset of patients with resectable disease has shown a favorable outcome with surgical treatment. Primary cutaneous HS is exceedingly rare and, to date, its long-term prognosis has thus not been well described. Here, we highlight two cases of primary cutaneous HS that showed long-term survival. Case 1 was a healthy 47-year-old woman who found a 12-mm tumor on her forehead. Case 2 was a 66-year-old woman, under follow up of a myxoid liposarcoma in her leg, who presented with a 25-mm tumor in her hypothenar eminence. Histologically, the tumors in both cases had a smooth outline with proliferating atypical tumor cells that showed histiocytic differentiation as revealed by immunohistochemistry with antibodies to CD68 (KP-1) and lysozyme in case 1; and CD68, lysozyme and CD163 in case 2. Tumor cells in case 1 had a monotonous appearance. After complete resection, cases 1 and 2 have survived for 10 and 4 years, respectively, without recurrence. To date, such patients are relatively long follow-up cases of survival from HS and highlight how a clear outline of the primary cutaneous HS tumor may be associated with its resectability and be an important factor in the assessment of its curability.

Abstract
Background Akathisia is a rather common extrapyramidal side effect of antipsychotic drugs and antidepressants, often resulting in severe discomfort for patients. However, due to the diversity of symptoms, it is often overlooked. We hereby report a case with akathisia that mainly appeared in an amputated leg. Case presentations A 60-year-old woman, who had undergone external hemipelvectomy for a recurrent soft tissue sarcoma, was referred to the Department of Psycho-Oncology due to worsening anxiety and restlessness. She was not unconscious or disoriented. Her chief complains included restlessness, an itching sensation in the area corresponding to the amputated left leg, and a feeling as if the lost left leg were raising itself. Detailed examination revealed that she had been administered 10 mg per day of oral prochlorperazine maleate for nausea induced by the oxycodone that had been prescribed to control post-operative pain. Akathisia was suspected and prochlorperazine maleate treatment was discontinued. All the symptoms were alleviated on the next day, and disappeared in 3 days. Eventually, she was diagnosed with akathisia. Conclusions This case indicates that the symptoms associated with akathisia can occur in an amputated extremity. Considering two previous reports of “phantom dyskinesia”, extrapyramidal syndromes may result in unusual presentations if occurring in an amputated extremity. Not only should the use of antipsychotic drugs and antidepressants be carefully considered, but also closer observation of psychological symptoms is required after prescription of these drugs because the clinical presentation of akathisia can be various and confusing due to modifications caused by other factors as in this case.

Abstract
Objective Eribulin, a microtubule dynamics inhibitor, is approved for the treatment of patients with breast cancer and soft tissue sarcoma. We investigated the efficacy and safety of eribulin in Japanese patients with soft tissue sarcoma. Methods This open-label, multicenter, nonrandomized, Phase 2 study enrolled Japanese patients with measurable, advanced/metastatic soft tissue sarcoma of high/intermediate grade and ≥1 prior chemotherapy for advanced disease. Patients received eribulin mesilate 1.4 mg/m2 intravenously over 2–5 minutes on Days 1 and 8 of a 21-day cycle. The primary endpoint was progression-free rate at 12 weeks. Secondary endpoints included overall survival, progression-free survival and safety. Efficacy analyses were stratified by histology (liposarcoma or leiomyosarcoma, and other subtypes). Results Overall, 52 patients were enrolled and 51 patients were treated. Patients with liposarcoma/leiomyosarcoma (n = 35) had similar characteristics to those with other subtypes (n = 16), except for a higher proportion of women (63% vs 38%, respectively) and patients with Eastern Cooperative Oncology Group performance status 0 (57% vs 44%). Progression-free rate at 12 weeks was 60% in liposarcoma/leiomyosarcoma patients, 31% in other subtypes and 51% overall. Median progression-free survival was 5.5 months in liposarcoma/leiomyosarcoma patients, 2.0 months in other subtypes and 4.1 months overall. Median overall survival was 17.0 months in liposarcoma/leiomyosarcoma patients, 7.6 months in other subtypes and 13.2 months overall. The most common Grade 3–4 adverse events were neutropenia (86%), leukopenia (75%), lymphopenia (33%), anemia (14%) and febrile neutropenia (8%). Conclusion Eribulin showed clinical activity with a manageable safety profile in previously treated Japanese patients with advanced/metastatic soft tissue sarcoma.

Abstract
We examined the sera of patients with Meniere's disease for the presence of antibodies against 8 inner ear antigens by enzyme-linked immunosorbent assay (ELISA). One hundred eight patients with Meniere's disease and 28 control subjects were studied. The antibodies against chicken type II collagen, bovine type II collagen, the cyanogen bromide cleaved peptide 11 (CB11) of each, type IX and XI collagens, C-Raf, and tubulin were measured by ELISA. The sensitivity of each antigen was between 37% and 60% individually, and was 91% when all 8 inner ear antigens were combined. These results showed that 91% of Meniere's disease sera have antibody activities to 1 or more of these inner ear antigens. The results suggest that performing ELISA for these 8 inner ear antigens was useful as a diagnostic tool for Meniere's disease. Further study is required for elucidating the role of these antigens in the pathogenesis of Meniere's disease, which might eventually result in better therapy.

Abstract
PURPOSE Limb-sparing resection of malignant pelvic tumours provides the opportunity for patients to obtain better post-operative mobility. However, because few studies have examined in detail the gait function of patients following pelvic tumour resection, the factors affecting gait performance remain to be clarified. Here, with the laboratory-based computer-assisted gait analysis, we evaluated these patients' gait objectively and the impact of a hip-stabilising supporter on gait improvement was simultaneously examined. METHODS Three-dimensional gait analysis was performed to obtain cross-sectional data for seven post-operative patients (mean age, 42.7 years; range, 20-61 years) who underwent various types of resection, including P1/4 internal hemipelvectomy (IH), P1/2/3 IH, and proximal femur resection with prosthetic reconstruction. To assess the immediate effects of a hip joint stabiliser, we instructed subjects to walk at their self-selected preferred speed and compared gait parameters with and without use of the hip stabiliser. RESULTS At baseline, the average walking speed was 0.75 m/s (95% CI 0.53-0.97). As shown by the intra-subject comparison, the hip stabiliser increased walking speed in all but one subject, increasing both temporal and spatial parameters. Ground reaction force of operated limbs increased for some subjects, while step length increased on at least one side in all subjects. CONCLUSIONS Improvement in the gait parameters is indicative of better control provided by the external hip stabiliser over the affected limb. Moreover, our findings show the potential of a biomechanical approach to improve gait function following pelvic tumour resection.

Abstract
Type 3 internal hemipelvectomy involves resection of the pubis. We report on 2 patients who underwent type 3 internal hemipelvectomy. One patient developed a bladder hernia, tumour recurrence, and a pathological fracture of the proximal femur. These were resolved with external hemipelvectomy 7 months later. Another patient underwent additional fascia lata transplantation to prevent development of hernia. Both patients had a stress fracture in the contralateral posterior ilium mimicking bone metastasis.

Abstract
We report the case of a 67-year-old male with bilateral proximal tibiofibular synostosis, presenting with unilateral symptoms. The patient complained of pain around the left fibular head, which was attributed to incomplete bone bridging between the proximal tibia and fibula; he underwent proximal fibular head resection, which alleviated the pain and improved knee mobility. Eleven months later, the patient continued to be pain-free and did not experience any adverse effects. An examination of this case and a review of similar cases revealed that participation in sport activities such as long-distance running may be one of the causes of proximal tibiofibular synostosis. In this report, we have also reconsidered the classification of proximal tibiofibular synostosis and provided information for a better understanding of this unusual condition.

Abstract
We report the case of a 78-year-old man with multiple bone tumours and three round, smooth nodules in the right lung. He was referred to our hospital because of the left femoral neck pathological fracture. The histological characteristics of the femoral tumour corresponded to clear cell carcinoma, and bone and lung lesions were regarded as metastatic from an unknown primary site, since there was no clinical evidence of renal carcinoma. His general conditions gradually declined, and he died 2 months after the operation. At autopsy, no neoplasia lesion was found in the kidneys. Although clear cell components were histologically dominant in the affected organs such as the lungs, bones and liver, neoplastic tubular structures also existed. Immunohistochemically, atypical cells were positive for napsin-A. The final diagnosis was adenocarcinoma of the lung origin with prominent clear cell features.

Abstract
We describe a new technique of pedicle freezing of the distal radius with malignant bone tumour and osteotomy of the normal ulna. The distal radius was sufficiently elevated to enable freezing without damaging adjacent tissues by releasing the distal radio-ulnar and radio-carpal joint and cutting the middle third of the ulna. The distal radius (including the tumour) was soaked in liquid nitrogen and the defect filled with iliac grafts. The ulna was repaired with plate and screws and was united at month 2. There was no local recurrence and the postoperative function score was 93%. This technique decreases the risk of non-union of the osteotomy site of the tumorous bone.

Abstract
BACKGROUND AND OBJECTIVES The KYOCERA Physio Hinge Total Knee System Type III (PHKIII) was developed to reconstruct bony defects of the distal femur. The PHKIII is originative in that the metallic parts are fully made of titanium alloy, and this prosthesis has a unique semi-rotating hinge joint and was designed especially for people with the Asian physical body-type. The clinical outcomes of the PHKIII after the resection of musculoskeletal tumors of the distal femur were evaluated. METHODS There were 41 males and 28 females with a median age of 48-years. The median duration of follow-up was 57 months. RESULTS Eleven early complications and 37 late complications were observed, including 10 recurrences, 7 deep infections, 7 aseptic loosenings, 4 stem breakages, 4 displacements of shaft cap, and one wear of rotation sleeve. Twenty four prosthesis (35%) required a secondary operation because of complications. The five-year overall prosthetic survival rates, -prosthetic survival rate without aseptic loosening, and -limbs preservation rate were 85%, 90%, and 86%, respectively. The mean functional score according to the classification system of the Musculoskeletal Tumor Society was 20.5 points (68%). CONCLUSIONS Although continuous follow-up is required, reconstructions using PHKIII are considered to achieve more acceptable functional results.

Abstract
BACKGROUND Although deep infection remains one of the most difficult complications to manage in the treatment of musculoskeletal tumor reconstructed with an endoprosthesis, limited information with respect to its incidence and risk factors has been reported. METHODS This multicenter, retrospective, uncontrolled study reviewed the medical records of 82 patients who underwent reconstruction with an endoprosthesis or temporary spacer for bone-immature patients after resection of malignant bone tumor around the knee. Risk factors for deep infection and the impact of deep infection on prosthesis survival and oncological outcomes were analyzed. Deep infection was defined according to the Centers for Disease Control and Prevention (CDC) guidelines with minor modification. RESULTS Deep infection occurred in 14 cases (17%), identified at a mean of 10.9 months (range <1 to 48 months) after initial surgery. Univariate analysis identified surface infection (P < 0.001) and skin necrosis (P < 0.001) as risk factors associated with deep infection. Conversely, tumor origin, chemotherapy, number of postoperative antibiotics, and length of bone resection were not associated with infection. Subclass analysis in femur cases identified a correlation between infection and the extent of partial resection of the quadriceps muscle (P = 0.04). In the multivariate analysis, surface infection represented an independent risk factor for deep infection (P = 0.03). Deep infection was a risk for endoprosthesis survival (P = 0.003) but did not affect the oncological outcome. CONCLUSIONS A strong correlation between the condition of soft tissue and establishment of deep infection is suggested in this study. Although practical options for preventing deep infection seem limited, the present data allow a form of perioperative evaluation for patients with a higher risk of deep infection.

Abstract
We report a rare case of late recurrence of a giant cell tumour (GCT) of bone 16 years after curettage and cryosurgery treatment. A 46-year-old man presented with swelling and progressively worsening pain in the lateral aspect of his right distal femur. He had undergone 4 procedures elsewhere to manage a GCT of bone and its recurrence 16 to 23 years previously. He underwent en bloc resection with an adequate wide margin and reconstruction with prosthesis. At the one-year follow-up, there was no evidence of recurrence or metastasis.

Abstract
PURPOSE To compare survival rates in the elderly with bone versus soft-tissue sarcomas. METHODS Records of 12 men and 8 women aged 70 to 91 (mean, 77) years with bone or soft-tissue sarcomas were retrospectively reviewed. The grade, size, location, and stage of the sarcomas, as well as their surgical margins, treatment modalities, local recurrence, metastasis, and prognosis were recorded. The mean follow-up period was 37 (range, 2-137) months. Their 5-year survival rates were estimated using the Kaplan-Meier method, and compared with 110 younger controls aged 9 to 69 (mean, 45) years during the same period. There was no significant difference between the older patients and younger controls regarding tumour grading (p=0.068, Chi squared test), stage, and pathological diagnosis. RESULTS Six patients had bone and 14 had soft-tissue sarcomas. Of the 6 bone sarcomas, 3 were malignant fibrous histiocytomas, 2 were osteosarcomas, and one was a chordoma; all were high grade, except for the chordoma. Of the 14 soft-tissue sarcomas, 9 were malignant fibrous histiocytomas, 3 were myxofibrosarcomas, one was a liposarcoma and one an extraskeletal osteosarcoma; all were high grade except for 2 of the myxofibrosarcomas and the liposarcoma. Of the 110 younger controls, 30 had bone and 80 had soft-tissue sarcomas; 44 were low grade and 66 were high grade. The 5-year survival rate was significantly lower in older patients than in younger controls (35% vs 65%, p=0.048). Regarding bone versus soft-tissue sarcomas, the 5-year survival rate was not significantly different among older patients (0% vs 52%, p=0.068) or younger controls 61% vs 66%, p=0.863). The difference was also not significant for older patients versus younger controls with bone sarcomas (0% vs 61%, p=0.284) or soft-tissue sarcomas (52% vs 66%, p=0.368), for older patients with high- versus low-grade sarcomas 17% vs 100%, p=0.314), for older patients with sarcomas located in the limbs versus the trunk (39% vs 38%, p=0.233), as well as for older patients versus younger controls with low-grade sarcomas (100% vs 92%, p=0.512) or high-grade sarcomas (17% vs 46%, p=0.269). CONCLUSION Survival rates tend to be lower in older patients with sarcomas, especially when the sarcoma is of bone and high grade.

Abstract
BACKGROUND The CD33 antigen is expressed on leukemia cells in most patients with acute myeloid leukemia (AML) and acute promyelocytic leukemia (APL), and in 20% of patients with acute lymphoblastic leukemia (ALL), while it is absent from pluripotent hematopoietic stem cells and nonhematopoietic cells. Gemtuzumab ozogamicin (GO) is an immunoconjugate of an anti-CD33 antibody linked to calicheamicin, which is a potent cytotoxic agent that causes double-strand DNA breaks, resulting in cell death. GO was developed against CD33 antigen-positive leukemias. The aim of this study was to investigate the cytotoxic effects of this agent in combination with conventional antileukemic agents. MATERIALS AND METHODS The cytotoxic effects of GO in combination with antileukemic agents were studied against human CD33 antigen-positive leukemia HL-60, U937, TCC-S and NALM20 cells. The leukemia cells were exposed simultaneously to GO and to the other agents for 4 days. Cell growth inhibition was determined using a MTT reduction assay. The isobologram method was used to evaluate the cytotoxic interaction. RESULTS GO produced synergistic effects with mitoxantrone, additive effects with cytarabine, daunorubicin, idarubicin, doxorubicin, etoposide and 6-mercaptopurine, and antagonistic effects with methotrexate and vincristine. CONCLUSION Our findings suggest that the simultaneous administration of GO with most agents studied would be advantageous for antileukemic activity. The simultaneous administration of GO with methotrexate or vincristine would have little cytotoxic effect, and this combination may be inappropriate. These findings may be useful in clinical trials of combination chemotherapy including GO or other monoclonal antibodies linked to calicheamicin.

Abstract
BACKGROUND The radiographic evaluation of the response to preoperative chemotherapy for bone and soft tissue sarcomas is based mostly on the change in primary tumor size before and after chemotherapy, as is done for many solid cancers. Its prognostic correlation, however, has hardly been validated. METHODS We conducted a retrospective validation study of the Japanese Orthopaedic Association (JOA) radiographic response evaluation criteria of preoperative chemotherapy for bone and soft tissue sarcomas as a JOA Committee on Musculoskeletal Tumors cooperative study. A total of 125 consecutive patients with high-grade bone (n = 77) and soft tissue (n = 48) sarcomas treated with neoadjuvant chemotherapy and definitive surgery in 25 tertiary referral hospitals were selected for the study. We investigated the correlation between the tumor size-based radiographic response evaluation criteria of preoperative chemotherapy for bone and soft tissue sarcomas provided by the JOA Committee on Musculoskeletal Tumors (hereafter called the JOA criteria) and the patients' overall survival using the Kaplan-Meier method and the log-rank test. RESULTS The JOA criteria correlated relatively well with survival for malignant bone tumors (mostly comprising osteosarcoma and Ewing's sarcoma) but not for soft tissue sarcomas, suggesting that the tumor size-based radiographic evaluation criteria for the response to preoperative chemotherapy in patients with soft tissue sarcomas is invalid. CONCLUSIONS The JOA criteria, based on the change in primary tumor size, is valid for malignant bone tumors but invalid for soft tissue sarcomas. Other new evaluation modalities of the response to preoperative chemotherapy using innovative functional imaging techniques are needed for soft tissue sarcomas.

Abstract
BACKGROUND The clinical features of extraskeletal osteosarcoma are not well known. Unlike osteosarcoma of the bone, the efficacy of chemotherapy for extraskeletal osteosarcoma has not been established yet. METHODS A multiinstitutional study of extraskeletal osteosarcoma was conducted. RESULTS A total of 20 patients were enrolled in the study from the Japanese Musculoskeletal Oncology Group institutions. Their ages ranged from 15 to 88 years (mean 50 years). Six lesions were located in the thigh, four in the chest, four in the buttocks, three in the upper arm, and others. UICC surgical stages were II in 5 patients, III in 13, and IV in 2. Surgical resection was performed in 19 patients, and the consequent surgical margin was wide in 15 patients, marginal in 3, and intralesional in 1. The overall 5-year survival rate was 66%. Three patients demonstrated tumor recurrence postoperatively, and the 5-year local control survival rate was 75%. Altogether, 15 patients received chemotherapy, of whom 11 had evaluable responses as follows: complete response in none, partial response in 5 patients, and no change or progressive disease in 6 patients, with a response rate of 45%. CONCLUSIONS Among the patients with extraskeletal osteosarcoma, both the 5-year survival rate and the chemotherapy response rate tended to improve in this study in comparison to the findings published in previous reports. As a result, we believe that treatment regimens that include systemic chemotherapy may be able to improve the prognosis in patients with extraskeletal osteosarcoma.

Abstract
Periosteal osteosarcoma is an exceedingly rare type of chondroblastic osteosarcoma, showing a rather good prognosis, and secondary bone marrow involvement is unusual. However, there have been some reports describing periosteal sarcoma involving medullary bone. We encountered a patient, a 38-year-old man, who had a bone surface tumor in the left tibia. An X-ray showed an erosive cortical mass extraosseous portion, located in the diaphysis of the tibia. Other images revealed a thin cortex, periosteal reactions, coarse mineralization in the extraosseous portion, and bone marrow involvement. Grossly, surgical materials showed that the tumor mainly existed at the periosteal portion, only a part of the cortex was destroyed, and there was medullary involvement throughout. Histological examinations showed a predominantly chondroid component with malignant osteoid formation. On the basis of the histological macroscopic and microscopic findings, we made the diagnosis of periosteal osteosarcoma with secondary bone marrow involvement.

Abstract
Bednar tumor (pigmented dermatofibrosarcoma protuberans) is a variant of dermatofibrosarcoma protuberans (DFSP) that constitutes 5% of all DFSP and has a very low rate of distant metastases. We encountered a rare case of Bednar tumor with multiple different distant metastases. A 51-year-old man, who had had a history of mass resection in his left shoulder 4 years previously, was referred to our institution, complaining of a recurrence of the shoulder mass. The histological diagnosis of primary tumor was Bednar tumor, and he underwent resectional surgery for the recurrent lesion. A second local relapse, lung metastasis, retroperitoneal metastasis, and metastasis to the sigmoid colon have occurred. The recurrence lesion and all metastatic lesions were resected surgically. The histological features of all specimens showed fibrosarcomatous change. Seven months after the last surgical resection, the tumor recurred and the patient died of multiple abdominal metastases 10 years after the first surgical treatment.

Abstract
Pemetrexed is a novel multitargeted antifolate with significant clinical activity against a variety of tumors. We studied the schedule-dependent cytotoxic effects of pemetrexed in combination with paclitaxel in vitro to improve our understanding of how this combination might be used clinically. Human lung cancer A549 cells, breast cancer MCF7, ovarian cancer PA1, and colon cancer WiDr cells were exposed to both pemetrexed and paclitaxel in vitro. Cell growth inhibition after 5 days was determined and the effects of drug combinations were analyzed by the isobologram method (Steel and Peckham). Simultaneous exposure to pemetrexed and paclitaxel for 24 h produced antagonistic effects in A549 and PA1 cells, additive/antagonistic effects in MCF7 cells, and additive effects in WiDr cells. Pemetrexed for 24 h followed by paclitaxel for 24 h produced synergistic effects in A549 and MCF7 cells and additive effects in PA1 and WiDr cells, while the reverse sequence produced additive effects in all four cell lines. Cell cycle analysis supported these observations. Our findings suggest that the simultaneous administration of pemetrexed and paclitaxel is suboptimal. The optimal schedule of pemetrexed in combination with paclitaxel is the sequential administration of pemetrexed followed by paclitaxel, and this schedule should be assessed in clinical trials for the treatment of solid tumors.

Abstract
Clear cell sarcoma is a rare malignant soft tissue neoplasm that usually arises adjacent to tendons or aponeuroses. The clinical course is rather slow, with repeated local recurrences followed by late metastases and eventual death. The principal sites of this neoplasm are the extremities, but tumors do occur in the trunk on rare occasions. We report a case of clear cell sarcoma arising from the chest wall. The patient, a 20-year-old woman, had noticed a chest wall mass and pain for 2 years. Biopsy of the mass showed abundant nests of round cells with clear cytoplasm. On immunohistochemical examination, tumor cells were strongly immunoreactive for S-100 and HMB-45. A diagnosis of clear cell sarcoma was confirmed. There was no other lesion found in the patient through routine imaging studies. She was treated with two courses of chemotherapy using ifosfamide, carboplatin, and etoposide. Subsequently, the tumor, including adjacent tissue, the chest wall, and sternum, was resected with a wide margin; and the defect of the chest wall was covered with Marlex mesh fabric, regin, and a musculocutaneous flap. She has shown no symptoms or signs of recurrence during 2 years of follow-up.

Abstract
Intraabdominal desmoplastic small round cell tumor (IDSRT) is a rare neoplasm, which is malignant and typically occurs in young adults. Although IDSRT is chemotherapy-sensitive, most cases do not achieve a complete response (CR). Even if some cases achieve a CR, they often relapse and result in poor prognosis. We report two cases of IDSRT, in a 24-year-old man and a 23-year-old man, who were treated with ifosfamide-based chemotherapy. Case 1, a 24-year-old man, presented with an abdominal mass, and the diagnosis of the biopsy specimen at laparoscopy was IDSRT. He received 7 courses of ifosfamide-based chemotherapy, which obtained a partial response (PR). He had no surgical resection, except for the biopsy procedure, and he underwent a total of 21 courses of chemotherapy. He died 36 months after diagnosis because of tumor regrowth and peritoneal bleeding. Case 2, a 23-year-old man, whose biopsy material allowed a diagnosis of IDSRT, was treated with 18 courses of chemotherapy, using ifosfamide, that resulted in a PR. This was followed by resection of the abdominal lesions, and he received an additional 2 courses of adjuvant chemotherapy. Four months after, completion of these 2 courses, the tumor recurred, and he died of diffuse pulmonary metastasis 36 months after diagnosis. This case report examines the results of ifosfamide-based chemotherapy in our two patients.

Abstract
OBJECTIVE The clinical features and the management of alveolar soft part sarcoma (ASPS) are not well known. The efficacy of chemotherapy for soft tissue sarcoma, including high-dose ifosfamide and cisplatin, has not been established yet. Some reports suggest ASPS may occur primarily in bone. METHODS We report on a series of 57 patients with ASPS over 20 years. Their ages ranged from 7 to 75 years (mean 25). RESULTS There were 37 females and 20 males. Thirteen lesions (23%) showed bone involvement at the primary site, and 6 of them were diagnosed as bone tumors at presentation. Thirty-seven patients had distant metastases at presentation. Tumor size, bone involvement at the primary site and the presence of metastases at presentation were prognostic indicators (p < 0.05). Marginal excision with radiotherapy or wide excision without radiotherapy achieved good local control. Chemotherapy was performed in 47 patients with different regimens. Two patients treated with intra-arterial chemotherapy regimens responded partially, but intravenous chemotherapy with high-dose ifosfamide or cisplatin failed. CONCLUSIONS ASPS can present primarily as a bone tumor. No advantage of chemotherapy with high-dose ifosfamide or cisplatin could be demonstrated.

Abstract
The posterior insula, central sulcus, and inferior parietal lobule including the intraparietal sulcus have been considered the vestibular cortex based on functional brain mapping in humans as well as experiments in lower primates. The same regions receive optokinetic, visual, and proprioceptive projections. We examined the cortical and subcortical projection of vestibular activity with visual and proprioceptive input eliminated during caloric stimulation (CS), using functional magnetic resonance imaging (fMRI). Single-shot gradient-echo echoplanar image (EPI) volumes were sensitive to BOLD contrast in oblique orientation. We adopted a pharmacokinetic model for analysis of imaging data from 10 subjects as a group. The insular gyrus, intraparietal sulcus, superior temporal gyrus, hippocampus, cingulate gyrus, and thalamus showed activation by CS. Cortical and subcortical activation during CS in the present study was observed within regions less precisely delineated by other methods. As intraparietal sulcus activation showed right hemispheric dominance, this region may have an oculomotor projection as well as the vestibular input.

Abstract
Raltitrexed (Tomudex) is a novel thymidylate synthase inhibitor with significant activity against advanced colorectal cancer. We studied the cytotoxic interactions of raltitrexed and 5-fluorouracil (5-FU) in four human colon cancer cell lines on various schedules. The cell growth inhibition after 5 days was determined using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The cytotoxic interactions at the IC80 level were evaluated by the isobologram method. Simultaneous exposure to raltitrexed and 5-FU for 5 days produced additive to synergistic effects in Colo201 cells, and produced additive effects in Colo321, LoVo, and WiDr cells. Simultaneous exposure to raltitrexed and 5-FU for 24 h produced additive effects in Colo201, LoVo, and WiDr cells, and produced antagonistic effects in Colo320 cells. Sequential exposure to raltitrexed for 24 h followed by 5-FU for 24 h produced additive effects in Colo201, Colo320, and LoVo cells, and produced antagonistic effects in WiDr cells. The reverse sequence produced additive effects in Colo201 cells, and produced antagonistic effects in Colo320, LoVo, and WiDr cells. Simultaneous exposure to raltitrexed and 5-FU for 4 h and sequential exposure to raltitrexed for 4 h followed by 5-FU for 4 h with a 20-h interval produced additive effects, while the reverse sequence produced antagonistic effects in LoVo and WiDr cells. These findings suggest that the simultaneous administration of raltitrexed and 5-FU or the sequential administration of raltitrexed followed by 5-FU may be the optimal sequence, while the reverse sequence may be inappropriate. Preclinical and clinical studies of the simultaneous administration of raltitrexed and 5-FU and the sequential administration of raltitrexed followed by 5-FU are required to better understand the antitumor, toxic, and pharmacokinetic interactions of this combination in order to develop the combination chemotherapy of raltitrexed and 5-FU.

Abstract
The additive cation effect on the oxidation-resistance of platinum supported on alumina was investigated by Pt L(III) and L(II)-edge XAFS. The white line intensity at Pt L(III)-edge of oxidized catalysts decreased with an increase in the electronegativity of the additive cation in the same way as the support effect previously reported: The addition of electrophilic cations make the supported platinum less oxidized state compared with the original Pt/Al2O3 and vice versa. Thus, it was revealed that the addition of more electrophilic cations provides the higher oxidation-resistance to platinum catalyst, even when platinum is supported on basic oxides.

Abstract
The folate-dependent enzymes are attractive targets for cancer chemotherapy. Methotrexate (MTX), which inhibits dihydrofolate reductase, has been widely used for the treatment of solid tumors and hematological cancers. Raltitrexed ("Tomudex") ), which inhibits thymidylate synthase, is a novel anticancer agent active against colorectal cancer and some other solid tumors. We studied the optimal schedule of raltitrexed and MTX in combination against four human colon cancer cell lines Colo201, Colo320, LoVo, and WiDr. These cells were simultaneously exposed to raltitrexed and MTX for 24 h, or sequentially exposed to raltitrexed for 24 h followed by MTX for 24 h, or vice versa. Cell growth inhibition after 5 days was determined by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The effects of drug combinations at the concentrations of drug that produced 80% and 50% cell growth inhibition (IC(80) and IC(50)) were analyzed by the isobologram method (Steel and Peckham, 1979). Cytotoxic interactions between raltitrexed and MTX were schedule-dependent. The simultaneous exposure to raltitrexed and MTX showed additive effects in Colo201, LoVo and WiDr cells and antagonistic effects in Colo320 cells. The sequential exposure to raltitrexed followed by MTX produced additive effects in all four cell lines. The sequential exposure to MTX followed by raltitrexed produced synergistic effects in Colo201, LoVo and WiDr cells and additive effects in Colo320 cells. These findings suggest that the sequential administration of MTX followed by raltitrexed produces more than the expected cytotoxicity and may be the optimal schedule at the cellular level. Further in vivo and clinical studies will be necessary to determine the toxicity and to test the antitumor effects of sequential administration of MTX followed by raltitrexed proposed on the basis of the in vitro synergism.

Abstract
The effect of fractions from a water extract of Polyporus on bladder tumor promotion was examined using 5% sodium saccharin (SS) in a short-term test with concanavalin A (Con A) in Wistar rats. Rats were given N-butyl-N-(4-hydroxybutyl) nitrosamine (BHBN) in drinking water for one week, and then promoter alone or test samples (given orally) plus promoter was administered for 3 weeks. Treatment with the BuOH fraction isolated from the water extract showed a strong inhibitory effect against the promoter. It was found that the inhibitory effect of the BuOH fraction is due to the effect of ergosterol contained in the fraction. Treatment with ergosterol showed a strong inhibitory effect against 5% SS, 0.01% BHBN, 3% DL-tryptophan (Trp) or 2% butylated hydroxyanisole (BHA); ID50 was 1.4 microg/kg/d, 2.9 microg/kg/d, 11.6 microg/kg/d, and 11.7 microg/kg/d against SS, BHBN, Trp and BHA, respectively. We also examined the effect of steroids and related compounds. Squalene and vitamin D2 showed strong inhibitory effect against 5% SS-induced bladder tumor promotion. These results strongly suggest that ergosterol could provide significant protection against the promotion of bladder tumor induced by many types of promoters in the environment.

Abstract
In order to confirm the crossed-innervation between auditory cortex and the ear that receives monosyllabic sound, the auditory cortical response to monaural monosyllabic stimulation as detected by functional magnetic resonance imaging (fMRI) was investigated in six normal hearing subjects. Stimulus amplitude averaged 95 dBSPL at the distal end of the audio system. A series of 440 echo planar images was acquired during the acoustic stimulation within the four OFF-ON cycle paradigm. Five image series with 10 slices were collected within each OFF or On period. Each scanning session began with four baseline images before the OFF-ON paradigm. Monosyllabic sounds were presented monaurally during the ON period at a rate of one monosyllable/sec. Functional MRI data were analyzed with SPM99b software (Statistical Parametric Mapping). The background scanner noise averaged 97dBSPL. The selicon ear plug and headphone as acoustic shields attenuated the noise as much as 17 dB. A broad and intense auditory cortical response was observed bilaterally in response to monaural monosyllable stimulation. Sound presentation to the right ear was followed by a larger response in the left auditory cortex than in the right, and left ear stimulation evoked a larger response in the right auditory cortex than in the left. This pattern was consistent in all subjects examined. The primary auditory cortex responded to monosyllabic words presented to the contralateral ear. The results confirmed the crossed-innervation between the auditory cortex and ear for listening to monosyllables. Functional MRI is a useful tool for investigating auditory cortex function, if the scanner noise is adequated controlled.
