A rare case: Mania associated with pazopanib

Mania typically presents with a well-denoted period of abnormal and persistently elevated or irritable mood, and increased activity or energy almost daily for at least a week. This mood disturbance is usually functionally dilapidating in aspects of social or occupational functioning, sometimes even requiring hospitalisation to prevent harm to self or others. We report an interesting case of first presentation of mania in a 61-year-old female with ongoing metastatic sarcoma, with a potential association with a chemotherapy drug – pazopanib.

Efficacy of temozolomide in pretreated patients with metastatic sarcoma.

e23550 Background: Sarcoma is a rare heterogeneous group malignancy and most commonly arises from soft tissue. The primary treatment modality is surgery. However, in metastatic disease, treatment options are limited. Cytotoxic chemotherapy is preferred for palliative treatment. This study aimed to assess the efficacy of temozolomide in heavily pretreated soft tissue sarcoma. Methods: We evaluated the patients with a metastatic various types of soft tissue sarcoma retrospectively. The patients with gastrointestinal stromal tumors and bone sarcomas were excluded from the study. We recorded the clinical, pathological, and treatment data of the patients. SPSS 25v was used for statistical analysis. Survival analysis was performed with the Kaplan-Meier method. Results: Sixteen patients were included in this study. The median age was 48 (range, 21-73) years. Six (37.5%) patients were de-novo metastatic. Tumor localizations were intra-abdominal (43.8%), extremity (31.2%), intrathoracic (12.5%), and head-and-neck (12.5%). The most common metastatic sites were lung (75%), bone (31.8%), liver (18.8%), respectively. For metastatic disease, the patients received at least two different chemotherapy regimens (75%), pazopanib (50%) and palliative radiotherapy (31.3%). Metastasectomy was also performed on five (31.3%) patients. Median progression-free survival was 3.5 (95% CI, 2.6-4.3) months. Partial response was observed in one (6.3%) patients, stable disease in four (25 %) patients. Eleven (68.8%) patients had progressive disease. Grade 1-2 adverse events were observed in nine (56.3%) patients, grade 3-4 in one (6.3%) patients. Conclusions: We showed that temozolomide was well-tolerated but had a limited efficacy for the treatment of patients with metastatic sarcoma. Treatment options for metastatic sarcomas are limited. Temozolomide may be considered a treatment option in patients with heavily pretreated soft tissue sarcoma.

Cell-surface vimentin positive circulating tumor cells as a diagnostic and prognostic indicator in pediatric sarcoma patients.

e15022 Background: Despite advances in care, the 5 year overall survival for patients with relapsed and or metastatic sarcoma remains as low as < 35%. Currently, there are no biomarkers available to assess disease status in patients with sarcomas and as such, disease surveillance remains only reliant on serial imaging which increases the risk of secondary malignancies and heightens patient anxiety. Methods: Here, we enumerated the cell surface vimentin (CSV+) CTCs in the blood of 92 sarcoma pediatric and adolescent and young adult (AYA) patients. Results: We discovered the CSV+CTC could serve as a possible biomarker of disease with sensitivity of 85.3% and specificity of 75%. Significantly, patients who were deemed to be CSV+ CTC positive were found to have a worse overall survival compared to those who were CSV+ CTC negative (773 days vs 2622 days). Addition of readily available genetic analyses improved the sensitivity in both diagnostic and prognostic tests. Conclusions: Our findings indicate that CSV+ CTCs have both diagnostic and prognostic value and can possibly serve as a measure of disease burden.
