Abstract Objective: By mining the TCGA database to look for immunotherapy targets of soft tissue sarcoma, and analyzed their biological behavior. Methods: The data of 265 samples were downloaded from the TCGA database to analyze the expression profile of soft tissue sarcomas. Research methods include immune and stromal scores, calculating DEGs, volcano maps and differential gene survival curves, gene enrichment analysis.Results: Kaplan-Meier survival curves showed that in the high immune score group, the total survival time was generally higher than that in the low immune score group. Analysis of the top ten terms resulted in the minimum P values for immune and inflammatory responses, plasma membrane, receptor activity, and chemokine activity. By plotting the K-M curves, we obtained 86 survivals related DEGs. Finally, the genes that can be used as independent risk factors for prognosis of soft tissue sarcoma were obtained by multivariate analysis of the DEGs. Conclusion: We believe that these genes are expected to be new targets for sarcoma immunotherapy and key genes for the analysis of prognosis of sarcoma.

Local recurrence of marginally excised subcutaneous soft tissue sarcomas is variable and difficult to predict. This study aimed to identify predictors of local recurrence after excisional biopsy. Medical records of 236 dogs from which tumors had been received between 2004 and 2007 were analyzed. Medium- to large-breed dogs, median age 10 years, were most commonly affected. A total of 139 tumors were graded histologically: 71 were grade 1 (51%); 59, grade 2 (42%); and 9, grade 3 (7%). Of these, 34 tumors (25%) were completely excised, and 104 (75%) were marginally excised. None of 30 completely excised tumors with follow-up information recurred. Three of 41 grade 1 tumors (7%), 14 of 41 grade 2 tumors (34%), and 3 out of 4 grade 3 tumors recurred after marginal excision. Kaplan-Meier survival curves were generated to evaluate survival and the tumor-free interval. The log-rank test and log-rank test for trend were used for comparisons. Tumor recurrence-free intervals for dogs with grade 1 and 2 tumors and for those with grade 1 and 3 tumors differed significantly ( P = .0027 and .0001, respectively) and overall were inversely related to tumor grade ( P = .0007). Kaplan-Meier survival curves, regardless of recurrence, for patients with grade 1, 2, or 3 tumors treated by marginal excision did not differ significantly, and none differed from the survival curves of patients treated by complete excision. In conclusion, histologic grade is a strong predictor for recurrence of marginally excised subcutaneous soft tissue sarcomas. Clean margins predict nonrecurrence. Tumor recurrence did not significantly reduce survival time.

Purpose. Flavopiridol is a potent cyclin-dependent kinase (CDK) inhibitor that has preclinical activity in many tumours. This synthetic flavonoid was tested in a phase II nonrandomized, nonblinded multicentre clinical trial to determine its activity and toxicity in patients with previously untreated metastatic or locally advanced soft tissue sarcoma.Methods. A total of 18 patients with histologically confirmed nonoperable soft tissue was treated with flavopiridol administered at a dose of 50 mg/m2IV over 1 hour daily×3days every 3 weeks.Results. Eighteen patients were accrued to the study over a period of 6 months. No objective responses were noted in the seventeen evaluable patients. Eight patients (47%) exhibited stable disease after 2 cycles (median duration of 4.3 months (range 1.4–6.9 months). Kaplan-Meier estimates for 3- and 6-month progression-free survivial rates were 44 percent and 22 percent, respectively. The only grade 3 toxicities were diarrhea (N=2), nausea (N=2), gastritis (N=1), and fatigue (N=1). Ninety-four percent of patients received≥90% of the planned dose intensity, during 55 treatment cycles.Conclusions. Flavopiridol was well tolerated at the dose and schedule used in this study, however, no objective treatment responses were seen and thus our results do not support further exploration of flavopiridol as a monotherapy at this dose and schedule in soft tissue sarcomas.

Introduction. The role of vinorelbine in specific soft tissue sarcoma subtypes is unclear. We present retrospective single institution experience with single-agent vinorelbine in subjects with metastatic soft tissue malignancies.Methods. Fifty-eight patients were treated with single agent intravenous vinorelbine between April 1997 and December 2004. Doxorubicin had been administered previously to 53 subjects (91%), and the median number of lines of previous chemotherapy was 3 (range 0–7).Results. Patients received a median 6 doses of vinorelbine (range 1–65). The overall response rate was 6%(3 patients: 1 angiosarcoma, 1 epithelioid sarcoma, and 1 embryonal rhabdomyosarcoma). Fourteen patients (26%) experienced a best result of stable disease. Median time to progression was 1.8 months (95%confidence intervals 1.5–2.1 months, Kaplan-Meier estimate). Eight patients experienced grade 3 or 4 toxicity, most commonly febrile neutropenia.Conclusion. Vinorelbine demonstrates limited activity in a heavily pretreated group of soft-tissue sarcoma patients. Prospective investigation may be considered for selected sarcoma subtypes.

Primary malignant cardiac tumors are rare, with a prevalence of about 0.01% among all cancer histotypes. At least 60% of them are primary soft tissue sarcomas of the heart (pSTS-h) that represent almost 1% of all STSs. The cardiac site of origin is the best way to classify pSTS-h as it is directly linked to the surgical approach for cancer removal. Indeed, histological differentiation should integrate the classification to provide insights into prognosis and survival expectancy of the patients. The prognosis of pSTS-h is severe and mostly influenced by the primary localization of the tumor, the difficulty in achieving complete surgical and pharmacological eradication, and the aggressive biological features of malignant cells. This review aims to provide a detailed literature overview of the most relevant issues on primary soft tissue sarcoma of the heart and highlight potential diagnostic and therapeutic future perspectives.

Background: Soft tissue sarcomas are a rare and heterogeneous group of malignant tumors of mesenchymal origin that comprise less than 1 percent of all adult malignancies. Although they occur anywhere in the body, they involve most commonly in extremities, trunk, retroperitoneum and head and neck. The aim of the study was to analyze clinical and histopathological features of various soft tissue sarcomas.Methods: This was a retrospective study, conducted in tertiary cancer centre in Odisha during the period 2015 to 2018. We collected clinical parameters like age, sex, site of swelling, any associated pain and biopsy reports and these variables were correlated with final histopathology reports.Results: A total of 107 patients were included in the study, with male to female ratio of 2:1(71 and 36) and average age of 43.45 years. All of them presented with a swelling. The lower extremities were the most common sites i.e. 44.62%. Pleomorphic sarcoma was the most frequent histologic variety comprising 43% and less frequent variety were angiosarcoma, and myxoid sarcoma.Conclusions: Soft tissue sarcoma are predominant in males and middle aged population are frequently affected. Most common affected site is lower extremity and pleomorphic sarcoma is the prominent histologic type.

Soft tissue sarcomas represent a heterogeneous group of malignant tumors that arise from mesenchymal tissues. The majority of these tumors arise on the extremity or trunk. Despite their rarity, soft tissue sarcomas continue to generate vigorous academic interest, and as a result, the ever-expanding medical literature dealing with sarcomas continues to grow. Many general surgeons will see few of these tumors during their careers, and a review of the current literature and how it applies to patients afflicted with soft tissue sarcoma of the extremity or trunk is warranted.

AbstractSoft tissue sarcomas are a heterogeneous group of neoplasias that due to their often clinically silent appearance often remain undetected or experience delayed treatment. Especially soft tissue swelling is often misinterpreted by patients and doctors and trivialized or verified with an incorrect biopsy technique. The hereby evoked complications for the patients are serious and may be reduced by simply following the available guidelines. The treatment of soft tissue sarcomas requires a close interdisciplinary coordination between specialists in tumor orthopedics, oncology, radiology, pathology and radiotherapy. On the basis of a selective literature review, the following article points out the current evidence on the treatment and illustrates a treatment algorithm.

In this retrospective study, we analysed the long-term oncological and functional results after extended ray resection for sarcoma of the hand. Recurrence-free and overall survivals were calculated using the Kaplan–Meier method. The function of the operated hand was assessed with the Michigan Hand Questionnaire and compared with the contralateral side. Extended ray resection was performed in 25 out of 168 consecutive patients with soft-tissue and bony sarcomas of the hand. The overall 5- and 10-year, disease-specific survival rates were 86% and 81%, respectively. Local recurrences were observed in two patients. The Michigan Hand Questionnaire score for the affected hand at follow-up in nine patients was 82 points versus 95 for the healthy contralateral hands. We conclude that extended ray resection of osseous sarcomas breaking through the bone into the soft tissue or for soft tissue sarcomas invading bone is a preferable alternative to hand ablation when excision can be achieved with tumour-free margins. Level of evidence: III
