Background: Vulvar sarcomas, which comprise less than 2% of vulvar malignancies, are a heterogeneous group of tumors. Sub-categorization of these tumors makes treatment strategies difficult to evaluate. "Proximal" type epithelioid sarcoma (PES) and malignant rhabdoid tumor (MRT) describe a rare subset of vulvar malignancies which share histologic features and an aggressive clinical course.
Case: We describe a case of vulvar PES/MRT in a 35 year old female treated with radical excision, inguinal-femoral lymphadenectomy, and adjuvant radiation who remains without evidence of disease 40 months after surgery. We review all English language reports of vulvar PES or MRT, and compare treatments and outcomes.
Conclusion: Vulvar PES/MRT is a rare disease attended by high rates of local and distant relapse. Radical excision remains the foundation of treatment. The role of adjuvant therapy, and particularly radiation, remains unclear but merits consideration.

AntiCancer Inc., San Diego, CA, U.S.A.;
Background/aim: Ifosfamide is used clinically with doxorubicin as first-line chemotherapy for soft-tissue sarcoma. However, ifosfamide efficacy for soft-tissue sarcoma is limited due to frequent occurence of ifosfamide resistance and thus more effective therapy is needed. The present study aimed to determine the synergy of recombinant methioninase (rMETase) plus ifosfamide against HT1080 human fibrosarcoma cells in vitro.

Background/aim: Soft tissue sarcoma (STS) is a mesenchymal tumor affecting multiple organs in dogs. Previous studies identified activation of the phosphatidylinositol-3 kinase (PI3K)/protein kinase B (PKB, AKT) pathway in canine STS cell lines and clinical samples, but the underlying mechanism remains unclear. This study investigated PTEN loss, PIK3CA mutation, and EGFR over-expression as potential drivers of PI3K/AKT pathway activation in STS.

Background/aim: Salmonella typhimurium A1-R (A1-R) targets and inhibits a wide range of cancer types without continuously infecting healthy tissue. Chloroquine, an antimalarial drug, induces apoptosis and inhibits autophagy in cancer cells. The aim of the present study was to determine the synergy of A1-R plus chloroquine on HT1080 human fibrosarcoma cells in vitro and in a nude-mouse model.

Background/aim: The present study aimed to assess the relationship between the maximum standardized uptake value (SUVmax) on F-fluorodeoxyglucose positron emission tomography computed tomography (F-FDG-PET/CT) and the geriatric nutritional risk index (GNRI) in patients with soft-tissue sarcomas (STSs).
Patients And Methods: The present single-center retrospective observational study included patients who underwent F-FDG-PET/CT and for whom serum albumin levels, height, and body weight were measured prior to therapeutic intervention.
Results: A total of 81 patients were included in the study.
