RESUMEN
Several life-prolonging therapies for metastatic castration-resistant prostate cancer (mCRPC) are available, including radium-223 dichloride (223Ra), which was approved based on phase 3 data demonstrating improved overall survival (OS) and a favorable safety profile. To date, real-world evidence for 223Ra use in Taiwan is from three studies of <50 patients. This observational study (NCT04232761) enrolled male patients with histologically/cytologically confirmed mCRPC with bone metastases from centers across Taiwan. 223Ra was prescribed as part of routine practice by investigators. Patients with prior 223Ra treatment were excluded. The primary objective was to assess 223Ra safety; secondary objectives evaluated efficacy parameters, including OS. Overall, 224 patients were enrolled. Most patients had an Eastern Cooperative Oncology Group performance status of 0/1 (79.0%) and ≤20 bone metastases (69.2%); no patients had visceral metastases. 223Ra was first- or second-line therapy in 23.2% and 47.7% of patients, respectively. The total proportion of patients who received 5-6 223Ra cycles was 68.8%; this proportion was greater with first-line use (84.3%) than second- (65.7%) or third-/fourth-line use (64.1%). More chemotherapy-naïve patients (61.9%) completed the 6-cycle 223Ra treatment than chemotherapy-exposed patients (56.7%). Any-grade treatment-emergent adverse events (TEAEs) and serious TEAEs occurred in 54.0% and 28.6% of patients, respectively, while 12% experienced 223Ra-related adverse events. Median OS was 15.7 months (95% confidence interval 12.13-19.51); patients receiving 5-6 223Ra injections and earlier 223Ra use had longer OS than those receiving fewer injections and later 223Ra use. 223Ra provides a well-tolerated and effective treatment for Taiwanese patients with mCRPC and bone metastases.

PURPOSE: To prospectively compare pain intensity and patient-reported outcomes (PROs) after arthroscopic rotator cuff repair (ARCR) between patients who received ultrasound-guided suprascapular nerve block (SSNB) and axillary nerve block (ANB) as well as preincisional parecoxib and patients who received preincisional parecoxib only. METHODS: Sixty-one patients receiving ARCR between March 2020 and March 2021 were prospectively enrolled. They were randomly assigned to the peripheral nerve block group (group N, n = 30) or control group (group C, n = 31). Two patients in group C were excluded because of miscommunication. All patients were administered 40 mg of parecoxib intravenously prior to induction of anesthesia. SSNB and ANB were performed after general anesthesia in group N, whereas no nerve block was performed in group C. Pain intensity was compared before surgery, as well as immediately, 24 hours, and 2 weeks after surgery. PROs, including the Oxford Shoulder Score, University of California-Los Angeles shoulder score, and Single Assessment Numeric Evaluation score, were compared before and 6 months after surgery. RESULTS: The numerical rating scale (NRS) score for resting pain was significantly lower in group N (4.9 ± 3.1 vs 7.6 ± 2.5, P < .001) immediately after surgery, but no difference was noted 24 hours after surgery. The resting pain NRS score 2 weeks after surgery was significantly lower in group N (1.4 ± 1.6 vs 2.7 ± 2.7, P = .03), but the scores for movement-evoked pain and night pain were similar. All PROs significantly improved 6 months after surgery in both groups, but there was no difference between the 2 groups. CONCLUSIONS: The addition of preoperative ultrasound-guided SSNB and ANB to parecoxib offered better resting pain control immediately and 2 weeks after ARCR, but there was no benefit for PROs 6 months after surgery. LEVEL OF EVIDENCE: Level II, prospective randomized controlled trial.
RESUMEN
Melanoma is rare in Taiwan. Asian melanoma is distinct from Western melanoma because acral and mucosal melanoma accounts for the majority of melanoma cases, leading to distinct tumor behaviors and genetic profiling. With consideration of the clinical guidelines in Western countries, Taiwanese experts developed a local clinical practice consensus guideline. This consensus includes diagnosis, staging, and surgical and systemic treatment, based only on clinical evidence, local epidemiology, and available resources evaluated by experts in Taiwan. This consensus emphasizes the importance of surgical management, particularly for sentinel lymph node biopsies. In addition, molecular testing for BRAF is mandatory for patients before systemic treatment. Furthermore, immunotherapy and targeted therapy are prioritized for systemic treatment. This consensus aimed to assist clinicians in Taiwan in diagnosing and treating patients according to available evidence.

BACKGROUND: Established associated factors for DDH include female sex, breech presentation, family history, congenital malformations, oligohydramnios, and maternal hyperthyroidism. However, evidence for environmental factors that may contribute to DDH is limited and inconsistent. METHODS: A systematic review of medical literature was conducted to collect data on environmental factors, including latitude, longitude, average yearly precipitation, average yearly temperature, minimum monthly temperature, and maximum monthly temperature, from all institutions that published articles on DDH. Univariate linear regression analysis was used to examine the correlation between environmental factors and DDH incidence, while multiple regression analysis was conducted to identify significant associated factors for DDH incidence. RESULTS: Data from a total of 93 unique manuscripts were analyzed, revealing a significant negative correlation between DDH incidence and temperature, including average yearly temperature (r = -0.27, p = 0.008), minimum monthly temperature (r = -0.28, p = 0.006), and maximum monthly temperature (r = -0.23, p = 0.029). Additionally, there was a significant positive correlation between DDH incidence and latitude (r = 0.27, p = 0.009), and a significant negative correlation between DDH incidence and average yearly precipitation (r = -0.29, p = 0.004). In the final multiple regression analysis, temperature, including average yearly temperature, minimum monthly temperature, and maximum monthly temperature, were identified as significant associated factors for DDH incidence. CONCLUSION: The findings of this study suggest an association between cold weather and DDH incidence. Further research should explore the link between cold weather and DDH incidence, offering insights into potential interventions for cold climates.

PURPOSE: Our study aimed to determine the impact of a novel technique of anesthesia administration on the clinical outcomes and complications in geriatric patients with severe systemic disease undergoing hip surgery. METHODS: We retrospectively identified patients aged > 65 years with severe systemic disease that was a constant of life [American Society of Anesthesiologists (ASA) IV] who underwent surgery for hip fracture between January 2018 and January 2020. The patients were divided into two groups: Group I [fascia iliaca compartment block plus propofol-based total intravenous anesthesia (FICB + TIVA)] and Group II [general anesthesia (GA)]. The primary outcomes were 30-day and 1-year mortality. The secondary outcomes included length of hospital stay, length of intensive care unit (ICU) stay, postoperative morbidity, Visual Analog Scale score, and consumption of analgesics. RESULTS: There was no significant difference in the 30-day mortality (5 vs. 3.8%, p = 0.85) and 1-year mortality (15 vs. 12%, p = 0.73) between the groups. Group I had significantly lower ICU requirements (p = 0.01) and shorter lengths of ICU stay (p < 0.001) and hospital stay (p < 0.001). Moreover, a smaller proportion of patients in Group I required postoperative morphine or oral opiates. CONCLUSION: Geriatric patients who underwent hip surgery under FICB + TIVA required fewer ICU admissions, shorter lengths of ICU and hospital stay, and had lesser postoperative opioid consumption than those who were under GA. Hence, we recommend the novel FICB + TIVA technique for hip fracture surgery in geriatric patients with poor general health status and high surgical risks (ASA IV).

PURPOSE: In the setting of acetabular dysplasia, the increased translational motion of the femur may damage the labrum and cartilage, as well as stretch the capsule. The purpose of the study was to investigate the relationship between the acetabular coverage and the capsular stiffness by assessing the distension of anterior and posterior joint recesses on the hip computed tomography arthrography. METHODS: One hundred thirty-three patients (138 hips) with a median age of 36 years (range 18-50 years) who received the computed tomography arthrography for evaluation of nonarthritic hip pain in our institute between 2015 and 2017 were retrospectively reviewed. The maximal distance between the anterior/posterior capsule and the anterior femoral head-neck junction/posterior femoral head on the axial imaging of computed tomography arthrography was defined as the width of anterior/posterior joint recess. The width of anterior/posterior joint recess was adjusted with the diameter of the femoral head and was then compared between acetabular dysplasia (lateral center-edge angle < 25°), normal acetabulum (lateral center-edge angle between 25 and 39°), and deep acetabulum (lateral center-edge angle > 39°). In addition, the standard univariate linear regression analysis was used to investigate the relationship between the adjusted width of anterior/posterior joint recess and anterior/posterior coverage of the hip, determined by the anterior/posterior wall index. RESULTS: The adjusted width of posterior joint recess was significantly greater in the acetabular dysplasia group than the normal acetabulum and deep acetabulum groups (p < 0.01 and p = 0.02, respectively). There was no significant difference of the adjusted width of anterior joint recess between the groups (n.s.). The adjusted width of posterior joint recess had a significant but weak negative correlation with the anterior wall index (r = - 0.25, p < 0.001), and no correlation with the posterior wall index (r = - 0.0004, n.s.). There was no significant correlation between the adjusted width of anterior joint recess and the anterior/posterior wall index (r = 0.05, n.s./r = 0.07, n.s.). CONCLUSIONS: The distension of posterior capsule on the computed tomography arthrography was significantly greater in acetabular dysplasia. In addition, there was a significant but weak negative correlation between the distension of posterior capsule and the anterior coverage of the hip. It indicated a looser posterior capsule was observed in a dysplastic hip. The relevance of posterior capsular laxity to clinical outcomes warrants further investigation. Given the fact that the distension of anterior capsule was not significantly higher in acetabular dysplasia, the need of anterior capsular plication in a dysplastic hip should be carefully evaluated. LEVEL OF EVIDENCE: Level III.

BACKGROUND: The traditional treatment for an instrumented vertebral fracture involves removing the loosened pedicle screws and extending the posterior instrumentation cephaladly or caudally. There has been a recent trend of performing minimally invasive fluoroscopy-guided percutaneous vertebroplasty as a salvage procedure. OBJECTIVE: The aim of this study was to compare the outcomes of surgical interventions for instrumented vertebral fracture. STUDY DESIGN: Retrospective assessment. SETTING: All data came from Chang Gung Memorial Hospital, Taiwan. METHODS: We retrospectively reviewed 35 patients with an instrumented vertebral fracture who underwent fluoroscopy-guided percutaneous vertebroplasty (Group I, n = 16) or extension of the posterior instrumentation (Group II, n = 19). Demographic data were recorded. The operating time, amount of intraoperative blood loss, time to postoperative ambulation, and duration of hospital stay were also evaluated. The visual analog scale (VAS) score, kyphotic angle on radiological images, Kirkaldy-Willis functional score, complications, and revision surgery were evaluated at one week and one, 3, 6, and 12 months postoperatively. RESULTS: Group I had a shorter operating time (P < 0.001), less intraoperative blood loss (P < 0.001), earlier postoperative ambulation (P < 0.001), and a shorter hospital stay (P < 0.001). The mean VAS score improved significantly after surgery in both groups (P = 0.001). The postoperative kyphotic angle was better in Group II (P < 0.05). There was no significant between-group difference in the Kirkaldy-Willis functional score at the last follow-up (P = 0.91). There was no significant between-group difference in the need for revision surgery (Group I, n = 4; Group II, n = 5; P = 0.93). LIMITATION: This study is a retrospective cohort. CONCLUSIONS: Minimally invasive fluoroscopy-guided percutaneous vertebroplasty can be used as an alternative to extension of posterior instrumentation for instrumented vertebral fracture. It has several advantages, including a shorter operating time, earlier postoperative ambulation, less blood loss, and a shorter hospital stay. The clinical outcomes of these 2 treatment approaches were similar.

BACKGROUND: To compare the outcomes after surgical intervention, including external fixation (EF) with the optional addition of K-pins or open reduction and internal fixation (ORIF) with a volar locking plate (VLP), in patients with distal radius fracture aged > 80 years. METHODS: We reviewed 69 patients with a distal radius fracture aged > 80 years who treated under surgical intervention from 2011 to 2017 retrospectively. Their demographic data and complications were recorded. Preoperative, postoperative, and last follow-up plain films were analyzed. The functional outcomes of wrist range of motion were also evaluated. RESULTS: 41 patients were treated with EF with the optional addition of K-pins, while 28 patients were treated with ORIF with a VLP. The radiological parameters, including ulnar variance and radial inclination, at the last follow-up were significantly more acceptable in the VLP group (p = 0.01, p = 0.03, respectively). The forearm supination was significantly better in patients treated with VLP (p = 0.002). The overall incidence of complications was lower in the VLP group (p = 0.003). CONCLUSION: VLP provides better radiological outcomes, wrist supination and lower complication rates than EF. Therefore, although EF is still widely used because of its acceptable results and easy application, we recommend VLP as a suitable treatment option for distal radius fracture in the geriatric population aged > 80 years.

OBJECTIVE: To investigate the correlation between the utilization of nuclear medicine diagnostic procedures and the mortality of women with breast cancer. SUBJECTS AND METHODS: Based on the National Health Insurance Research Database (NHIRD), we studied female breast cancer patients in 2012 who underwent whole-body bone scan, lymphoscintigraphy, or fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) for possibly managing breast cancer metastases. The mortality of breast cancer was then followed up in 2017. Multiple linear regression analysis was applied to analyze the correlation between the use of any of these three nuclear medicine procedures and the mortality of breast cancer. RESULTS: For patients with early-stage breast cancer, single lymphoscintigraphy was the most frequently performed nuclear medicine procedure, accounting for 36.4% of all three nuclear medicine procedures. For patients with late-stage breast cancer, single whole-body bone scan was the most frequently performed nuclear medicine procedure, accounting for 67.2% of all three nuclear medicine procedures. Mortality of breast cancer significantly increased with the prevalence of late-stage breast cancer (b=2.87, P=0.001) and significantly decreased in cases in which whole-body bone scan was used (b=-4.28, P=0.003). CONCLUSION: The mortality of women with late-stage breast cancer was negatively related to the utilization of whole-body bone scan but not to the utilization of lymphoscintigraphy or the 18F-FDG PET/CT scan. In women with early-stage breast cancer, no significant correlation existed between breast cancer mortality and the utilization of the above three nuclear medicine procedures.

We appraised Warburg effect through analysis of mitochondrial DNA (mtDNA) copy number and maximum standard uptake value (SUVmax) of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) scan and their alterations in esophageal squamous cell carcinoma (ESCC). Later T-status and longer longitudinal tumor length were associated with lower mtDNAESCC copy number (pâ¯<â¯.05) but higher SUVmax-ESCC (pâ¯<â¯.05), respectively. Lower mtDNAESCC copy number correlated with higher SUVmax-ESCC, reciprocally (pâ¯<â¯.05). ESCCs expressing mutant p53 protein had lower mtDNAESCC copy number (pâ¯=â¯.056) but higher SUVmax-ESCC (pâ¯=â¯.046). We conclude that mutant p53 protein may be involved in the Warburg effect of ESCC.

We retrospectively analyzed the impact of initial positron emission tomography and computed tomography (PET-CT) complete remission (CR) and time to next treatment (TTNT) on patient outcome in follicular lymphoma. Between 2002 and 2014, 150 patients could be evaluated for treatment response and long-term outcome. The CR after first line treatment with either rituximab-cyclophosphamide, oncovin, and prednisolone (R-COP) or rituximab-cyclophosphamide, doxorubicin, oncovin, and prednisolone (R-CHOP) was 89% and partial response (PR) was 7%. The 5- and 10-year survival rates were 86.0% and 62.6%, respectively. In five years, 11% of patients had died of lymphoma and 3% from other causes. Forty-seven patients (31%) underwent a second line of treatment comprising 19 (40%) with a TTNT shorter than 24 months and 28 (60%) longer than 24 months. There was no difference in overall survival (OS) between R-COP (86%) and R-CHOP (77%) at 5 years, but there were more next treatment events in the R-COP compared with the R-CHOP group on longer follow-up (60% versus 35% at 8 years). For PET-CT response, there was a significant OS difference between initial CR and PR patients (88% versus 70%, p < 0.01), and a longer TTNT was seen in initial CR patients. Patients with a TTNT longer than 24 months had better OS compared with patients with a shorter TTNT (93% versus 54% at 5 years, p < 0.01). In conclusion, patients with initial PET-CT CR and TTNT longer than 24 months had better OS compared with those achieving only PR and shorter TTNT. PET-CT CR should be considered the treatment goal during initial treatment, and more aggressive treatment should be considered for patients with a TTNT of less than 24 months.
RESUMEN
PURPOSE: FDG PET that has been used is good for diagnosing asymptomatic colorectal cancer (CRC) recurrence in patients with elevated serum carcinoembryonic antigen (CEA) level. However, there is no reference level of CEA rise that would universally suggest the necessity of a PET study. The purpose of this retrospective study was to identify the high-risk group of CRC recurrence through an examination of the dynamics of the CEA level rise as a recurrence indicator. PATIENTS AND METHODS: Between July 2002 and May 2010, 112 patients (59 men, 53 women; age, 18-87 years) had FDG PET for suspicious CRC recurrence indicated by elevated CEA level. We reviewed the PET results and the medical records for recurrence verification and calculated the ratio of increase and the velocity of change in CEA levels for risk stratification. RESULTS: The patient-based sensitivity, specificity, and accuracy of PET are 96.6%, 91.3%, and 95.5%, respectively. The probability of recurrence positively correlated with the CEA level rise and the newly diagnosed disease stage. Carcinoembryonic antigen level greater than 13 ng/mL indicated significantly higher risks of recurrence. In patients with CEA level rise of 13 ng/mL or less, an increase over 3.34 times the individualized baseline also indicated high risks of recurrence. CONCLUSIONS: A posttreatment CEA level rise to greater than 13 ng/mL is suggestive of the optimal use of FDG PET, and so is a mild increase below 13 ng/mL at an increase rate over 3.34.

Medulloblastoma, a malignant, invasive embryonal tumor of the cerebellum, occurs most often in children. It has high metastatic potential and is usually treated by aggressive multimodal therapy, including surgery, chemotherapy and craniospinal irradiation. Multiple secondary tumors have been reported following craniospinal irradiation. It is rare with the occurrence of oligodendroglioma after irradiation. In this report, we described a patient with secondary oligodendroglioma after postoperative craniospinal irradiation for medulloblastoma.

PURPOSE: The purpose of this study is to evaluate the performance of gallium-67 scan (GS) and F-18 fluorodeoxyglucose (FDG) PET scan in lymphoma staging and recurrence detection by comparing the 2 imaging studies in the same patient. MATERIALS AND METHODS: A total of 42 patients from the period between July 2002 and May 2006 were included in this study. Of the 42 patients, 6 had Hodgkin disease and 36 had non-Hodgkin lymphomas. All of them underwent one or more FDG PET scans and also underwent corresponding GS performed within 7 days of FDG PET, for staging or detection of lymphoma recurrence. Among the non-Hodgkin lymphoma cases, 18 were diffuse large B-cell lymphoma, 10 were follicular center cell lymphoma, and 8 were of other types. Of the total 46 pairs of imaging performed in these 42 patients, 27 were for staging, and 19 for restaging after recurrence. RESULTS: In all these studies, FDG PET detected 230 lesion sites, whereas GS detected 85 lesion sites. All of the lesions detected by GS were noted on FDG PET, whereas GS detected only 37.0% of the lesions detected by FDG PET. Among the 27 studies for staging, FDG PET detected 120 lesions, whereas GS detected 68 lesions (56.7%). In the 19 images taken for relapse, FDG PET detected 110 lesions, whereas GS detected only 17 (15.5%). CONCLUSIONS: FDG PET is superior to GS in staging and detecting all types of lymphoma. The difference is notably more significant in recurrence detection.
