Abstract
Cutaneous sarcomas comprise a heterogeneous group of mesenchymal spindle cell tumors of the dermis and subcutis, one of the best-known entities being dermatofibrosarcoma protuberans. Other sarcomas addressed in this review include a typical fibroxanthoma, cutaneous undifferentiated pleomorphic sarcoma, leiomyosarcoma, liposarcoma, and angiosarcoma. With the exception of dermatofibrosarcoma protuberans, which has its peak incidence in middle-aged adults, cutaneous sarcomas usually occur in elderly individuals starting in the sixth or seventh decade of life. The pathogenesis of the various disease entities is not uniform and has not been definitively ascertained. Histology is the key to arriving at a correct diagnosis, and should always include ruling out other dermal neoplasms such as melanoma. In recent years, molecular genetic methods have provided greater insight into the pathogenesis, thus paving the way for new targeted therapies. Treatment of choice for cutaneous sarcomas is excision with sufficient surgical margins. Adjuvant and neoadjuvant therapeutic concepts include radiation therapy and the use of targeted therapies or chemotherapies. Local recurrences have frequently been reported in cutaneous sarcomas. Unlike soft tissue sarcomas, the prognosis in terms of survival - with the exception of angiosarcoma - is very good if treated adequately, a fact that should be emphasized to patients.

Abstract
Myxoid sarcoma (MLS) is one of the most common types of malignant soft tissue tumors. MLS is characterized by the FUS-DDIT3 or EWSR1-DDIT3 fusion oncogenes that encode abnormal transcription factors. The receptor tyrosine kinase (RTK) encoding RET was previously identified as a putative downstream target gene to FUS-DDIT3 and here we show that cultured MLS cells expressed phosphorylated RET together with its ligand Persephin. Treatment with RET specific kinase inhibitor Vandetanib failed to reduce RET phosphorylation and inhibit cell growth, suggesting that other RTKs may phosphorylate RET. A screening pointed out EGFR and ERBB3 as the strongest expressed phosphorylated RTKs in MLS cells. We show that ERBB3 formed nuclear and cytoplasmic complexes with RET and both RTKs were previously reported to form complexes with EGFR. The formation of RTK hetero complexes could explain the observed Vandetanib resistence in MLS. EGFR and ERBB3 are clients of HSP90 that help complex formation and RTK activation. Treatment of cultured MLS cells with HSP90 inhibitor 17-DMAG, caused loss of RET and ERBB3 phosphorylation and lead to rapid cell death. Treatment of MLS xenograft carrying Nude mice resulted in massive necrosis, rupture of capillaries and hemorrhages in tumor tissues. We conclude that complex formation between RET and other RTKs may cause RTK inhibitor resistance. HSP90 inhibitors can overcome this resistance and are thus promising drugs for treatment of MLS/RCLS.

Abstract
Liposarcoma (LPS) is the most common type of soft-tissue sarcoma. Complete surgical resection is the only curative means for localized disease; however, both radiation and conventional cytotoxic chemotherapy remain controversial for metastatic or unresectable disease. An increasing number of trials with novel targeted therapy of LPS have provided encouraging data during recent years. This review will provide an overview of the advances in our understanding of LPS and summarize the results of recent trials with novel therapies targeting different genetic and molecular aberrations for different subtypes of LPS.

New frontiers in the treatment of liposarcoma, a therapeutically resistant malignant cohort. Drug Resist Updat 2010; 14:52-66.

Abstract
The adipogenic origin-derived liposarcoma (LPS) family is the most common soft tissue sarcoma histological subtype. This group is composed of three categories as per the 2002 WHO guidelines: (1) well-differentiated and dedifferentiated liposarcoma (WDLPS/DDLPS); (2) myxoid and round cell liposarcoma (MLS and RCL); and (3) pleomorphic liposarcoma (PLS). While clustered together, these histological subtypes are widely diverse in their clinical, pathological, and molecular characteristics. In general, surgery still remains the mainstay of LPS therapy and the only approach offering the potential of cure. Effective therapeutic strategies for locally advanced and metastatic disease are currently lacking and are crucially needed. With the current gradually increasing knowledge of LPS genetic- and epigenetic-associated deregulations, the ultimate goal is to develop drugs that can specifically eliminate LPS cells while sparing normal tissues. This tumor-tailored target-orientated approach will hopefully result in a significant improvement in the outcome of patients suffering from these poor prognosis malignancies.
