RESUMEN
BACKGROUND: Working while receiving cancer treatment is challenging for patients, with considerable impact on their quality of life (QOL). However, there have been no reports on the factors that prevent employment in patients with bone metastases. This study aimed to investigate the employment status and factors impacting the continued employment of patients with bone metastases. METHODS: We analyzed clinical data from new patients consulting The University of Tokyo Hospital team for bone metastasis treatment between June 2015 and September 2017. Patients who were working at the time of cancer diagnosis (n = 124) completed four QOL questionnaires. Factors associated with work sustainability were identified via univariate analysis and a chi-squared test. Multivariate logistic regression analysis was used for significant variables. Relationships between employment and QOL scales were investigated using the Wilcoxon rank-sum test, with P < .05 considered as statistically significant. RESULTS: Among the 124 patients, only 45 (36.3%) were still working when the questionnaire was administered. Multivariate analysis revealed temporary employment, lytic or mixed bone metastases, and lower limb or acetabular metastasis, as significant factors hindering work sustainability. The QOL scores were high in the continued employment group. However, the relationship between employment status and pain remains unclear. CONCLUSIONS: Lytic or mixed bone metastases and the lower limb and acetabular metastasis were significantly associated with employment resignation. Mobility difficulties may prevent patients with bone metastases from sustaining employment. Collaboration between rehabilitation professionals, oncologists, and workplaces is imperative to address this problem.
RESUMEN
BACKGROUND: Even terminal cancer patients desire to walk to the toilet by themselves until the very last day. This study aimed to describe the walking ability of patients with spinal metastases at the end-of-life stage and identify the factors affecting this ability. METHODS: Among 527 patients who first visited our multidisciplinary team for bone metastasis between 2013 and 2016, 56 patients who had spinal metastases with a Spinal Instability Neoplastic Score ≥7 and died during follow-up were included. We collected general clinical data, performance status, Frankel classification, epidural spinal cord compression scale and Spinal Instability Neoplastic Score at the first consultation. Patients' last day of walking and date of death were also examined. Univariate analyses (chi-squared tests) were performed to identify the factors that impacted walking ability 30 and 14 days before patients' death. RESULTS: A total of 56 patients were extracted, and 57.1% (32/56) and 32.7% (16/49) of patients were ambulatory 30 and 14 days before death, respectively. Their performance status (P = 0.0007), Frankel grade (P = 0.012) and epidural spinal cord compression grade (P = 0.006) at the first examination, and administration of bone modifying agents during follow-up period (P = 0.029) were significantly related to walking ability 30 days before death. Among ambulatory patients 30 days before death, those with Spinal Instability Neoplastic Score ≥10 (P = 0.005), especially with high scores of collapse (P = 0.002) and alignment (P = 0.002), were less likely to walk 14 days before death. The walking period in the last month of their life was significantly longer in patients with total Spinal Instability Neoplastic Score 7-9 (P = 0.009) and in patients without collapse (P = 0.040) by the Wilcoxon test. CONCLUSION: The progression of spinal metastasis, especially neurological deficit, at the initial consultation were associated with walking ability 30 days before death, and spinal stability might be crucial for preserving walking ability during the last month. Early diagnosis and implementation of appropriate bone management might be important for the end-of-life walking ability.

OBJECTIVE: To conduct an exploratory examination of caregiver burden involving toilet problems in patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD) and related characteristics. METHODS: We included 50 outpatients with amnestic MCI and AD and their caregivers. Patients were subclassified into three groups: MCI, mild AD, and moderate/severe AD. We used the Japanese version of the Zarit Burden Interview (J-ZBI) to evaluate caregiver burden and conducted a questionnaire on the frequency of lower urinary tract symptoms and related caregiver burden. We compared the frequency of questionnaire items with the level of burden in each group and subsequently determined the J-ZBI correlation coefficient. RESULTS: Among the questionnaire items, the caregiver's burden of "increased daytime urinary frequency," "nocturia," "urinary incontinence," and "they cannot clean the toilet" statistically significantly correlated with J-ZBI scores (ρ = 0.52, 0.65, 0.79, and 0.83, respectively). Items including "they cannot clean the toilet," "the smell of excrement is bothersome," "assistance for transfer is necessary," "they soil the clothes and bed," and "they cannot clean the genital region" were significantly more common in the patient group with moderate/severe AD. CONCLUSIONS: Lower urinary tract symptoms and toilet problems were significantly correlated with caregiver burden. Toilet problems differ depending on the severity of dementia. Therefore, a support system based on dementia severity is required to address toilet problems.

OBJECTIVE: It remains unclear which factors contribute to dysphagia recovery after an acute stroke. This study aimed to identify factors associated with complete oral intake recovery in patients with post-stroke dysphagia. METHODS: Data were obtained from the Diagnosis Procedure Combination database, which is a nationwide database of administrative claims and discharge abstracts in Japan. We selected patients admitted within 3 days of stroke onset and conducted multivariable logistic regression analysis. Total oral intake within 30 days of admission was the primary outcome measure. RESULTS: A total of 151,302 patients were included, and total oral intake was observed in 48% of them within 30 days of admission. Total oral intake was significantly associated with age, sex, stroke subtype, consciousness disturbance, low body mass index, multiple comorbidities, and the modified Rankin Scale before stroke onset. In addition, males had worse outcomes than females (odds ratio, 0.75; 95% confidence interval, 0.73-0.77, p < 0.001), and intracerebral and subarachnoid hemorrhagic stroke subtypes were associated with non-recovery. CONCLUSION: This study identified several prognostic factors for total oral intake in patients with acute stroke. These results may be useful for predicting a patient's dysphagia prognosis at the time of admission and designing a nutritional management plan for patients with acute stroke.

BACKGROUND: Eribulin is a tubulin and microtubule-targeting drug that has clinical benefit in overall survival (OS) for patients with advanced soft tissue sarcoma. Eribulin's efficacy has been confirmed in several clinical trials, although no clinically useful biomarkers have been identified. We therefore sought to clarify the predictive factor of eribulin treatment, while focusing on systemic inflammation and immune response values. METHODS: This study included 33 advanced STS patients treated with eribulin between March 2016 and September 2019. We evaluated the associations of clinical factors influencing the efficacy of eribulin treatment and systemic inflammatory and immune response, including the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), the lymphocyte-to-monocyte ratio (LMR), the systemic inflammation response index (SIRI), and the prognostic nutrition index (PNI), with progression-free survival (PFS) and OS using the Kaplan-Meier method and log-rank test. RESULTS: NLR, LMR, PLR, SIRI, and PNI were unassociated with PFS. Compared with patients with SIRI <1.5, those with an SIRI ≥1.5 had a significantly shorter OS [median OS 15 months (95% confidence interval [CI] 8-not reached) vs. 7 months (95% CI 3-14), P = 0.04]. Moreover, the PFS tended to be shorter for patients with SIRI ≥1.5 who received chemotherapy after eribulin treatment than in those with SIRI >1.5 [median PFS 92.5 days (95% CI 27-204) vs. 133 days (95% CI 36-507), P = 0.08]. CONCLUSIONS: High SIRI values may predict poorer overall survival and the efficacy of subsequent drugs after eribulin treatment among patients with advanced soft tissue sarcoma.

OBJECTIVE: Malignant fungating wounds are ulcerating tumors that infiltrate the overlying skin. Little evidence exists regarding the prognosis or treatment of malignant fungating wound in soft tissue sarcoma. This study aimed to reveal the prognosis and outcome of surgical treatment of malignant fungating wound in soft tissue sarcoma. METHODS: We retrospectively reviewed 26 patients with malignant fungating wound in high-grade soft tissue sarcoma between 2005 and 2018. The patients' characteristics, treatments, surgical wound complications, local recurrences and prognoses were analyzed. Overall survival was analyzed using the Kaplan-Meier method and compared with that of the control cohort, consisting of 236 consecutive patients with non-malignant fungating wound high-grade soft tissue sarcoma treated during the same period. RESULTS: Among the 26 patients, undifferentiated pleomorphic sarcoma was the most common subtype. Twenty-three patients, including 20 (87%) and 3 (13%), underwent limb-salvage surgery and amputation, respectively. Among the 20 patients who underwent limb-salvage surgery, 4 (20%) had surgical wound complications, which required additional surgical procedures. Excluding the patients who underwent palliative surgery, local recurrence occurred in 2 patients (11%). The 5-year overall survival rate for all high-grade malignant fungating wound and non-malignant fungating wound patients was 26.0 and 67.3% (P < 0.0001), respectively. CONCLUSIONS: Malignant fungating wounds in soft tissue sarcoma were significantly associated with a poor prognosis; however, the incidence of surgical complications and local recurrence after limb-salvage surgery was comparable to that of general soft tissue sarcoma cases. Limb-salvage surgery should be considered, if possible, to preserve the patient's quality of life because of the dismal prognosis of patients with malignant fungating wound in soft tissue sarcoma.

BACKGROUND: Surgical procedure for symptomatic spinal metastasis is expected to improve the quality of life. Factors related to short-term perioperative mortality after surgery for spinal metastasis may be different from those related to long-term mortality, which have classically been used to determine the indication for surgery. The purposes of this study were to evaluate factors related to the 30-day mortality after surgery for spinal metastasis and create an integer risk scoring system. METHODS: Using the Diagnosis Procedure Combination database from 2010 to 2016, we extracted data of patients who underwent surgical procedure for spinal metastasis. Multivariable logistic regression analysis was performed to clarify the association between patient backgrounds and the 30-day postoperative mortality. We created a risk scoring system using regression coefficients to estimate the 30-day mortality for each patient. RESULTS: Among 3524 patients, the 30-day mortality was 2.6%. Factors associated with a higher 30-day mortality were male sex (odds ratio, 2.50 [95% confidence interval, 1.45-4.31]), emergency admission (1.80 [1.11-2.92]), rapid growth tumors (3.83 [2.49-5.90]), and non-skeletal metastasis (2.27 [1.42-3.64]). In patients with the maximum risk score of five, the 30-day mortality was 16.2%. CONCLUSIONS: Factors related to the 30-day mortality were male sex, emergency admission, rapid growth tumors, and non-skeletal metastasis. These findings provide spine surgeons and patients knowledge of the potential risk of short-term perioperative mortality and allow them to consider the risk of surgery.

BACKGROUND: Phosphaturic mesenchymal tumors primarily cause tumor-induced osteomalacia, a rare paraneoplastic syndrome, and half occur in soft tissues. There are few reports about the surgical margins of these tumors. This study aimed to clarify the optimal surgical margin for phosphaturic mesenchymal tumors by analyzing radiological and histopathological features. METHODS: This study included eight cases, seven primary and one recurrent, of tumor-induced osteomalacia caused by soft-tissue phosphaturic mesenchymal tumors that were surgically treated between January 2000 and January 2019. We evaluated the radiological and histopathological features of all tumors and investigated the correlation of these features, the surgical margin, and recurrence of hypophosphatemia. RESULTS: The tumors were located in superficial (n = 5) and deep (n = 3) tissues. Six of the eight tumors had a clear boundary, but five had an irregular margin. Three tumors had a hypointense rim on T2-weighted images, indicating fibrous tumor encapsulation. Histopathological analysis revealed infiltrative growth in six of the eight tumors, which correlated with an irregular margin seen on imaging. Although there was no recurrence in patients treated with an intended wide margin >1 cm, one of the three patients treated with marginal tumor resection experienced a recurrence of hypophosphatemia, with histopathological analysis showing infiltration of subcutaneous fat. In contrast, two tumors with clear boundaries, regular margins, and fibrous capsule seen on imaging, had no infiltrative growth and were cured by marginal resection. In one recurrent case, tumor infiltration was observed in the previous surgical scar, which was not detected on preoperative imaging. CONCLUSIONS: Soft-tissue phosphaturic mesenchymal tumors with an irregular boundary seen on imaging tend to be infiltrative, especially into subcutaneous fat, and should be treated by at least a 1-cm wide margin resection. Tumors with a fibrous capsule with clear and regular margins are cured by marginal margin resection. These findings could inform surgeons' decisions regarding the resection of soft-tissue phosphaturic mesenchymal tumors.

BACKGROUND: Soft tissue metastasis is rarer than bone metastasis. Patients with soft tissue metastasis generally have a dismal prognosis. The treatment for metastatic lesions is sometimes difficult, because the prognostic factors of patients with soft tissue metastasis remain unelucidated. Therefore, this study aimed to identify these prognostic factors. METHODS: Thirty-one patients with soft tissue metastasis were included in the study. We evaluated associations of overall survival with clinical parameters and inflammatory markers using Kaplan-Meier curves and Cox proportional hazards models. RESULTS: Twelve patients received surgery for soft tissue metastasis, while radiation therapy was performed in six cases. The median overall survival after the detection of soft tissue metastasis was 11 months. Univariate analysis revealed that detection of soft tissue metastasis after the multidisciplinary treatment (P = 0.01); solitary metastasis (P = 0.0003); and pretreatment C-reactive protein (CRP) level < 0.4 mg/dL (P < 0.0001), white blood cell count < 8500 × 103/µL (P = 0.0003), and neutrophil-to-lymphocyte ratio < 5 (P = 0.02) were significant good prognostic factors. Multivariate analysis revealed that a CRP value < 0.4 mg/dL (P = 0.07) and solitary metastasis (P = 0.09) were possible significant predictors of survival. Furthermore, in case of CRP levels <0.4 mg/dL and metastatic tumor resection, patients had a good prognosis; however, when the CRP levels increased to 0.4 mg/dL and above, patients had a poor prognosis, irrespective of tumor resection. CONCLUSIONS: CRP is potentially useful for determining the indication of radical metastasectomy in soft tissue metastasis.

BACKGROUND: Myxoid liposarcoma (MLS) has the tendency to metastasize extrapulmonary. Although prognostic factors at the initial diagnosis of MLS have been reported, those at diagnosis of metastasis remain unclear. The purpose of this study was to investigate the prognostic factors for disease-specific survival at the initial diagnosis of metastasis. METHODS: This retrospective observational study was conducted at three cancer centers and two university hospitals in Japan. Of 274 MLS patients pathologically diagnosed between 2001 and 2015, 48 metastatic patients were examined. RESULTS: Lung metastases were detected in nine patients (18.8%) and extrapulmonary metastases in 45 (93.8%). Interval from primary diagnosis to the first metastasis was significantly shorter in patients with lung metastases than without (p = 0.007). Median disease-specific survival after diagnosis of metastases was 52.5 months in all patients. In multivariable analysis, liver metastasis (hazard ratio (HR), 2.71 [95% confidence interval (CI), 1.00-7.09]) and no evidence of disease (NED) achieved by radical treatment (resection with or without radiation therapy, or radiation therapy ≥60 Gy) or semi-radical (radiation therapy ≥40 Gy) treatment were significantly related to survival (HR, 0.36; 95%CI [0.13-0.95]). The number of metastases (odds ratio (OR), 0.44; 95%CI [0.25-0.78]) and abdominal/retroperitoneal metastases (OR, 0.09; 95%CI [0.008-0.95]) were the significant inhibitory factors of achieving NED. CONCLUSIONS: This is the first study to statistically demonstrate the importance of achieving NED with surgical resection or radiation therapy for longer survival in metastatic MLS patients. As number of metastases was a significant factor for achieving NED, early detection of metastases might be important.

OBJECTIVE: In contrast to acrometastasis, defined as bone metastasis to the hand or foot, the frequency and prognosis of bone metastasis of other limb segments remain unclear. To compare prognosis according to sites of bone metastasis, we defined two new terms in this study: 'mesometastasis' and 'rhizometastasis' as bone metastasis of 'forearm or lower leg' and 'arm or thigh', respectively. METHODS: A total of 539 patients who were registered to the bone metastasis database of The University of Tokyo Hospital from April 2012 to May 2016 were retrospectively surveyed. All patients who were diagnosed to have bone metastases in our hospital are registered to the database. Patients were categorized into four groups according to the most distal site of bone metastases: 'acrometastasis', 'mesometastasis', 'rhizometastasis' and 'body trunk metastasis'. RESULTS: The frequency of rhizometastasis (22.5%) or body trunk metastasis (73.1%) was significantly higher than that of acrometastasis (2.0%) or mesometastasis (2.4%). The median survival time after diagnosis of bone metastases for each group was as follows: 6.5 months in acrometastasis, 4.0 months in mesometastasis, 16 months in rhizometastasis, 17 months in body trunk metastasis and 16 months overall. In survival curve, there was a statistically significant difference between mesometastasis and body trunk metastasis. CONCLUSIONS: Our findings suggest that 'mesometastasis' could be another poor prognostic factor in cancer patients and that patients with mesometastasis should receive appropriate treatments according to their expected prognosis.

OBJECTIVE: The factors associated with health-related quality of life in patients with glioma remain unclear; particularly, the impact of symptoms on quality of life has not been studied comprehensively. This study aims to document the quality of life of patients with glioma and clarify the impact of symptoms. METHODS: In this cross-sectional study, participants were recruited from patients at The University of Tokyo Hospital and from patients who were registered at the Japan Brain Tumor Alliance. We included adult patients with World Health Organization grade II-IV glioma and excluded those with disturbances of consciousness or aphasia. We used the European Organization for Research and Treatment of Cancer QLQ-C30 and BN20 to evaluate quality of life and the symptoms. Multiple regression analyses were performed to investigate the impact of symptoms on European Organization for Research and Treatment of Cancer global health status and QLQ-C30 social functioning. In addition, we performed univariate subgroup analyses classified by World Health Organization grade and history of chemotherapy. RESULTS: This study included 76 patients. Seven symptoms occurred in more than 50% of the patients: fatigue, future uncertainty, drowsiness, communication deficit, financial difficulties, motor dysfunction and weakness of legs. Multiple regression analyses showed that insomnia affected their global health status, and appetite loss, financial difficulties and motor dysfunction were significantly related to their social functioning. In subgroup analysis, the number of symptom subscales that were significantly related to global health status and social functioning was larger in World Health Organization grade II patients compared with grade III/IV patients. CONCLUSIONS: In addition to neurological deficits, symptoms were associated with poor quality of life in patients with glioma. This study provided the basis on further investigation of usefulness of symptom evaluation on quality of life improvement.

BACKGROUND: It is unknown whether sarcopenia influences treatment outcome in patients with soft tissue sarcoma. Herein, we aimed to elucidate the impact of sarcopenia on sarcoma treatment. METHODS: A total of 163 soft tissue sarcoma patients were included. Skeletal muscle measures were calculated using computed tomography images. Skeletal muscle area (SMA) and density (SMD) at the L3 level were extracted, and SMA was normalized by height as skeletal muscle index (SMI). The skeletal muscle gauge (SMG) was calculated by multiplying SMD × SMI. The relationship of skeletal muscle measures and clinical factors to wound complications and prognosis was evaluated, and classification and regression tree (CART) analysis was used to develop classification models for risk groups of surgical wound complications. RESULTS: Thirty-three patients developed wound complications. In univariate analysis, age (P = 0.0022), tumour location of adductor compartment of the thigh (P = 0.0019), operating time (P = 0.010), blood loss (P = 0.030), SMD (P = 0.0004) and SMG (P = 0.0001) were significantly correlated with complications. In multivariate analysis, lower SMG was an independent risk factor (P = 0.031, OR = 3.27). CART analysis classified three risk groups of surgical wound complications by SMG, age, tumour location and operating time, and area under the receiver operating characteristic curve (AUROCC) was 0.75. SMG was not associated with prognosis in univariate analysis (P = 0.15). CONCLUSIONS: The SMG does not affect overall survival but predicts surgical wound complications.

Fibrodysplasia ossificans progressiva (FOP) is a rare genetic skeletal disorder manifesting progressive heterotopic ossification (HO) and congenital malformation of the great toes. Since 2007, we have conducted research on FOP. Here, we review the findings on FOP published to date, including the results of our research. Epidemiological studies in Japan have indicated that FOP has nearly the same prevalence in Japan as in the rest of the world. Basic research on its pathoetiology has progressed rapidly since the identification of the causal gene in 2006. Clinical and radiological findings have been thoroughly researched, including early radiological signs, and diagnostic criteria were established, designating FOP as an intractable disease in Japan. In patients with FOP, the progression of HO is associated with numerous disabilities, often manifesting in vicious cycles that can lead to early mortality. Through cross-sectional and short-term longitudinal studies, we have explored patient education, quality of life, and activities of daily living among Japanese patients. The management of FOP requires education of patients and caregivers, the use of medications to settle inflammation and flare-ups, instructions to ensure proper oral care, and other compensatory approaches that aid in rehabilitation. An avoidance of medical intervention, which may cause HO to progress, is also important. The advent of new drugs to prevent HO could have clinical benefit.

BACKGROUND: The Toronto Extremity Salvage Score (TESS) is the most widely used patient-reported outcome measure for orthopaedic oncology patients. However, minimal clinically important differences (MCIDs) in the TESS have not been analyzed. The aim of this study was to define the MCIDs of TESS in patients with lower extremity sarcoma. METHODS: A total of 85 patients were investigated to calculate the MCIDs for TESS. Three different methods were used: 1) distribution-based methods based on one-half of the standard deviation and standard error of measurement (SEM) at the baseline, 2) anchor-based and receiver operating characteristic (ROC) analysis, and 3) anchor-based using Akaike's Information Criterion (AIC) analysis. RESULTS: The MCIDs at 6 months were 4.9-7.8 by distribution-based methods and 4.3-4.4 by anchor-based methods. The MCIDs at 12 months were 4.0-6.9 by distribution-based methods and 10.6-11.6 by anchor-based methods. CONCLUSIONS: We calculated MCID values for the TESS based on distribution- and anchor-based approaches. Our results seem reasonable since MCIDs calculated by the different approaches had similar values. This knowledge will enable clinicians to identify meaningful functional improvements in sarcoma patients.

AIMS: To clarify longitudinal change of lower urinary tract symptoms (LUTS) and various types of urinary incontinence following robot-assisted radical prostatectomy (RARP) using validated questionnaires. MATERIALS AND METHODS: The core lower urinary tract symptom score (CLSS) and the International Consultation on Incontinence Questionnaire (ICIQ)-Short Form (SF) questionnaires were administered to 607 consecutive, treatment-naïve men receiving RARP before and after surgery. The time course of comprehensive LUTS and various types of urinary incontinence, including stress-, urgency-, and urinary incontinence with no obvious reason, were evaluated. Continence recovery rates were compared for the different types of incontinence using Cox hazard regression analysis. RESULTS: After surgery, stress urinary incontinence (SUI) was reported most frequently (32% of cases) as the chief complaint with the most impact on daily life, as assessed by the CLSS questionnaire, followed by urgency urinary incontinence (UUI; 27% of cases). The rates of continence recovery differed among the different types of urinary incontinence, such as after urinating, when dressed, when asleep, when physically active or exercising, when coughing or sneezing, before reaching the toilet, and for no obvious reason. Incontinence for no obvious reason at 1 month after RARP was a strongest prognostic factor of delayed continence recovery (hazard ratio, 0.61; P < 0.0001), whereas patients reporting SUI and UUI gradually regained continence. CONCLUSIONS: Further time course on continent recovery after RARP would be more precisely predictable based on the incontinence status at one month postoperatively. Especially, incontinence with no obvious reason would be a significant factor for delayed recovery.

AIMS: The efficacy of perioperative pelvic floor muscle training (PFMT) for continence recovery after robot-assisted radical prostatectomy (RARP) remains unclear. Visualization of the bladder neck and urethra using transperineal ultrasound (US) may promote self-recognition of urethral closure during PFM contraction. This study aimed to examine whether transperineal US-guided PFMT promotes early recovery of post-RARP incontinence. METHODS: This prospective cohort study included 116 men undergoing RARP. All men were offered to undergo transperineal US-guided PFMT, and 36 men agreed. The protocol consisted of biofeedback PFMT using transperineal US before RARP and 1-month after RARP with verbal instruction of PFMT immediately after urethral catheter removal. The remaining 80 patients received verbal instruction for PFMT alone. Continence recovery was defined as the number of days requiring a small pad (20 g) per day by self-report. RESULTS: No differences were observed in demographic or peri-operative parameters between the two groups except the longer operative time in the US-guided PFMT group. The mean time until continence recovery was significantly shorter in the US-guided PFMT group (75.6 ± 100.0 days) than in the verbal-PFMT group (121.8 ± 132.0 days, P = 0.037). Continence recovery rates within 30 days were 52.8% (19/36) and 35.4% (28/80) in the US-guided PFMT and verbal-PFMT groups, respectively (P = 0.081). US-guided PFMT was associated with better postoperative continence status (adjusted hazard ratio [95% confidence interval]: 0.550 [0.336-0.900], P = 0.017). CONCLUSIONS: The results showed that transperineal US-guided PFMT perioperatively was associated with early recovery of urinary continence after RARP.

BACKGROUND: With the improvement in survival of hepatocellular carcinoma patients, extrahepatic metastases have become a more frequent complication. Although pathological fractures or paralysis due to bone metastases deteriorate the quality of life of patients, no treatment guideline for bone metastases has been established. This study aimed to clarify the risk factors for these events and the clinical course of patients with bone metastases. METHODS: Out of 783 hepatocellular carcinoma patients treated in our institution between 2009 and 2016, 76 patients with bone metastases were enrolled. They were divided into two groups by the trigger of bone metastases detection. One was those diagnosed by surveillance (surveillance group), and the other was those based on symptom presentation (non-surveillance group). We investigated the clinical features, risk factors for fractures or paralysis and prognostic factors for survival after bone metastases. RESULTS: Baseline characteristics and survival were not significantly different between two groups. Fractures or paralysis occurred in 10 patients (13.2%), and the frequency was significantly higher in the non-surveillance group (20.9%) than the surveillance group (3.0%) in univariate analysis (p = 0.036). The median survival after diagnosis of bone metastases was 11.7 months. Age over 75 years (p = 0.002), hepatitis C-virus etiology (p = 0.007) and Child-Pugh class B/C (p < 0.001) were significantly associated with a shorter survival in multivariate analysis, but fractures or paralysis did not affect the survival. CONCLUSIONS: Early diagnosis through surveillance for hepatocellular carcinoma bone metastases may prevent fractures or paralysis and lead to a better quality of life for these patients.

BACKGROUND: Despite the clinical benefits of eribulin on overall survival of advanced soft tissue sarcoma (STS) patients, treatment-related toxicity reduces their QOL. Body composition metrics (BCMs) are associated with poor outcome and drug toxicities in several cancers. This study investigated whether BCMs could predict drug toxicity occurrence in advanced STS patients treated with eribulin. METHODS: This study included 23 advanced STS patients treated with eribulin between March 2016 and April 2018. BCMs were evaluated using a CT scan obtained within 1 month before or after treatment initiation. The relationship of BCMs and other clinical factors was evaluated and CART analysis used to develop classification models for risk groups of drug toxicity. RESULTS: Sixteen patients (69.6%) experienced any grade 3/4 toxicity. Eleven patients (47.8%) developed G4 hematologic toxicity, which was significantly higher in those with low skeletal muscle gauge (SMG) (P = 0.02) and low pretreatment neutrophil count (P = 0.0002). Six patients (26.1%) had grade 3/4 non-hematologic toxicity, and was higher in those with low SMG (P = 0.004), and low serum albumin level (P = 0.02). Five patients with high BMI (P = 0.03) experienced febrile neutropenia (FN) and low pretreatment neutrophil count (P = 0.02). CART analysis classified three risk groups, and area under the receiver operating characteristic curve (AUROCC) was 0.92, 0.88, 0.92 in G4 hematologic AE, G3/4 non-hematologic AE, FN, respectively. CONCLUSIONS: SMG is a significant predictive factor of eribulin drug toxicity in advanced STS patients. Risk classification of drug toxicity through combining predictive factors, could improve the therapeutic strategy used in chemotherapy.

BACKGROUND: Schwannomas are well-encapsulated, benign neoplasms, and enucleation is a standard operation procedure. The incidence of neurological complications after surgical treatment for schwannomas of the extremities varies, and there is no consensus concerning predictive factors for complications. The aim of this study was to elucidate predictive factors for complications after surgical treatment of schwannomas that develop in the major nerves of the extremities. METHODS: A total of 139 patients with 141 schwannomas arising in major nerves were retrospectively analyzed. Data regarding preoperative clinical features, the postoperative neurological complications, and clinical course of complications, with a median follow-up period of 2 months (range, 0.5-96), were obtained. Predictive factors for complications were statistically analyzed. RESULTS: Postoperative complications occurred in 49 lesions (34.8%), including 42 with sensory disturbance and 8 with motor weakness. In univariate analysis, older age, tumors originating from the upper extremity, and major motor nerve involvement were associated with a higher complication rate (p = 0.03, p = 0.003, and p = 0.001, respectively). In multivariate analysis, major motor nerve involvement was an independent predictive factor for postoperative complications (p = 0.03). Almost all complications gradually improved, but 6 out of 8 patients with motor weakness did not show full recovery at the final follow-up. CONCLUSIONS: Schwannomas originating from major motor nerves can lead to a higher risk for postoperative complications.
