Clinical Outcome and Survival of Osteosarcoma Patients in Cipto Mangunkusumo Hospital: Limb Salvage Surgery versus Amputation

Aim: to analyze the outcome and survival rate of osteosarcoma patients in our hospital as well as the factors affecting prognosis and functional outcome. Methods: this is a retrospective cohort study of osteosarcoma patients in Cipto Mangunkusumo Hospital underwent limb salvage surgery (LSS), amputation, LSS + amputation, and refused surgery from year 1995 to 2014. The surgical decision was based on patient’s age, staging, location, neurovascular involvement, Huvos type, functional demand, patient preference, and general condition. Functional outcome was assessed using the Musculoskeletal Tumor Society (MSTS) score with the maximum score of 30. Results: subjects consisted of 80 male and 52 female aged 4 to 61 year-old. They underwent limb salvage surgery (LSS) (n=37), amputation (n=42), LSS + amputation (n=2), and refused surgery (n=51). Overall 5-year cumulative survival rate was 14.6%. The 5-year survival rate for each group; LSS, amputation, combined LSS and amputation, and refused surgery was 34.8%; 15.9%; 0%; and 0%, respectively. Patients with tumor size <8 cm tend to underwent LSS compared to amputations (60.7% vs 39.3%, p=0.046). Local recurrence-free survival for LSS and amputation was 96.2% and 86.5% respectively (p=0.586). MSTS score was higher in LSS than amputation group (25.0 vs 18.5, p=0.011). Conclusion: LSS had higher survival rate than amputation in osteosarcoma patients who were treated in Cipto Mangunkusumo Hospital. MSTS functional score in the LSS group was higher than amputation group

Measurements of Patellofemoral Morphology Characteristics in Indonesian Population: an MRI Based Study

Patellar malalignment is the imbalance relationship between patella and trochlea, in which clinical findings most of the time are obscured; hence diagnosis is often challenging. Magnetic resonance imaging (MRI) is the most sensitive tool to detect subtle patellar malalignment features, so diagnosis can be made early. However, there has been no clear consensus on the normal value of patella morphology until today. This study aims to determine patellofemoral morphology values in Indonesian using MRI. This was a retrospective study of 202 patients aged 18-40 years old with knee problems without patellar instability. Patellar morphology parameters including Insal Savati ratio (IS ratio), patellar tilt angle (PTA), sulcus angle (SA) and tibial tubercle-trochlear groove distance    (TT-TG) were evaluated and recorded for statistical analysis. There was no significant correlation between anthropometric values and patellar morphology values. There were significantly higher PTA, SA and TT-TG values in females compared to males. The mean value of the IS ratio in the Asian population using MRI was 0.99 ± 0.14, PTA was 9.09 ± 6.88, SA was 139.20 ± 6.38, and TT-TG distance was 8.00 ± 5.25. Further studies with larger samples and multi-center results are required

The role of actors in implementing policies for the protection of child victims of sexual violence in Aceh

Protection of child victims of sexual violence is a very important issue in Aceh, Indonesia. Children, as a vulnerable group, need strong protection and support to overcome the negative impacts that may arise from sexual violence. In this context, many actors implement child protection policies, including the central government, DPR RI, regional governments, and institutions such as the Indonesian Child Protection Commission (KPAI) and the Witness and Victim Protection Agency (LPSK). This research uses a descriptive qualitative approach with literature study methods and online data search. Data analysis techniques involve organizing data, coding, and developing descriptions and themes. It is hoped that the results of this research will provide a better understanding of the role of policy actors in protecting children from sexual violence. This article identifies these actors and describes their role in implementing policies to protect child victims of sexual violence in Aceh. These actors' roles include legislation, supervision, assistance, trauma recovery, legal assistance, motivation, and collaboration between institutions. The analysis results show that cooperation and coordination between these actors is very important to ensure that children who are victims of sexual violence receive comprehensive protection. As awareness of the importance of child protection increases, this article provides a better understanding of how these actors play a role in protecting children in Aceh from sexual violence

Clinical Outcome Following Prolonged Neoadjuvant Chemotherapy and Delayed Surgery in Osteosarcoma Patients: An Evidence-based Clinical Review

Background: The incidence of osteosarcoma reached 16.8 cases annually at dr. Cipto Mangunkusumo Hospital in 1995-2008. Previous studies suggested that prolonged neoadjuvant chemotherapy followed by delayed surgery improves the clinical outcome. Prolonged neoadjuvant chemotherapy followed by delayed surgery commonly occurs in Indonesia, as diagnostic imaging and surgery waiting list will delay the surgery. The aim of this study is to observe the survival rate and the event-free survival rate of osteosarcoma patients with prolonged neoadjuvant chemotherapy and delayed surgery. Methods: This review included randomized controlled trials (RCTs), cohort studies, retrospective cohort studies, clinical trials, and reviews. Literature search was conducted through MEDLINE (PubMed search engine), Cochrane Central Register of Controlled Trial, and Scopus. The studies were screened and selected according to inclusion criteria by author and contributors independently. Results: Six studies were included in the qualitative synthesis of this study. Overall survival rate, event-free survival rate, histological response and recurrence as well as neoadjuvant chemotherapy duration, cycle and regiment were assessed in this study. Conclusion: Prolonged neoadjuvant chemotherapy and delayed surgery results in 5-years survival rate of 43.2% to 96.6% and 5-years event-free survival rate of 35.7% to 86.4%

Association between laboratory markers and oncological outcomes in patients with osteosarcoma – A review of osteosarcoma treatment in Indonesia

Background: Treatment of osteosarcoma requires multi-disciplinary team work and a rigorous follow-up schedule to achieve best oncological and functional outcomes. However, standard treatment and routine image study may not be available for all Indonesian patients because of complex geographic reason in Indonesian archipelago. Therefore, we aimed to review treatment outcome of osteosarcoma in Indonesia and validate potential laboratory markers associated with oncological outcomes. Materials and Methods: From January 2015 to August 2016, we retrospectively reviewed 57 patients with osteosarcoma who had received treatment in Dr. Cipto Mangunkusumo Hospital (RSCM), Jakarta, Indonesia. Association between laboratory markers including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), lactate dehydrogenase (LDH), alkaline phosphatase (ALP) and oncological outcomes including mortality and distant metastasis have been validated. Results: Our results showed that a combination of neoadjuvant chemotherapy, tumor resection and adjuvant chemotherapy would lead to the best oncological and functional outcome. ESR, CRP LDH and ALP level decreased after surgery and chemotherapy. Lower level of ESR and CRP were not associated with less distant metastasis and less mortality. On the other hand, the elevated LDH was correlated with higher mortality (P < 0.01), whereas elevated ALP was also correlated with a higher risk of distal metastasis (P = 0.044). Conclusions: Patients who had been properly treated with neoadjuvant chemotherapy, tumor resection and adjuvant chemotherapy had the best oncological and functional outcomes. LDH and ALP might be useful laboratory markers to predict oncological outcome

Low-grade intramedullary osteosarcoma presenting with multiple sclerotic bone lesions

Low-grade intramedullary osteosarcoma is a less-aggressive type of osteosarcoma for which delays in diagnosis are common. We present the case of a 42-year-old woman with complaints of low back pain. Multiple imaging evaluations and biopsy procedures were necessary to make the final diagnosis. The key radiologic feature was multiple sclerotic lesions throughout the skeleton, best seen on the bone scan. The difficulties in diagnosing this condition are evident in this case.
