Four different treatment strategies in aggressive fibromatosis:A systematic review

Background: The treatment approach for aggressive fibromatosis is changing. Although surgery is the mainstay in common practice, recent literature is reporting a more conservative approach. We compared the local control rate for surgery, surgery with radiotherapy, radiotherapy alone and a wait and see policy in a systematic review. Methods: A comprehensive search of the databases PubMed/Medline, Embase and Cochrane, of the medical literature published in 1999 till March 2017 was performed by two reviewers, including articles about extra abdominal aggressive fibromatosis without the genetical variants. A total of 671 studies were assessed for eligibility, and 37 studies were included for analysis, representing 2780 patients. Results: The local control rates for surgery alone, surgery and radiotherapy, radiotherapy alone and observation were 75%, 78%, 85% and 78%, respectively. For patients with recurrent disease observation had a better local control rate than surgery alone (p = 0.001). In the observation group, stabilization of the tumor was seen in median 14 (range 12–35) months. The time to local recurrence in the treatment group was median 17 (range, 11–52) months. Conclusion: A watchful conservative first line approach with just observation and closely monitoring, by means of physical examination and MRI, appears to be justified in a subgroup of patients without clinical symptoms and no possible health hazards if the tumor would progress.

Isolated limb perfusion of soft tissue sarcomas:A comprehensive review of literature

<p>Patients with primary irresectable, locally advanced soft tissue sarcomas of the limbs form a challenging group for the treating physician. Multimodality treatment is necessary to guarantee optimal limb salvage and survival rates. Since the introduction of isolated limb perfusion in the late fifties, several treatment regimens have been proposed. Isolated perfusion with melphalan and TNF-alpha, as part of a multimodality treatment, is regarded as the current best treatment option today. Ongoing studies are investigating potential benefit of other doses, new chemotherapeutic agents and new techniques in perfusion and radiotherapy. This article provides a historical overview of published literature and insight in upcoming treatment techniques. (C) 2012 Elsevier Ltd. All rights reserved.</p>

Radiation-Associated Angiosarcoma After Breast Cancer: High Recurrence Rate and Poor Survival Despite Surgical Treatment with R0 Resection

Secondary angiosarcoma of the breast is a rare but severe long-term complication of breast cancer treated with breast-conserving surgery and radiotherapy. We characterized a population-based cohort of patients with secondary angiosarcomas from two tertiary hospitals to investigate this complication with respect to surgical treatment and outcome. We identified 35 patients with a history of radiation for breast cancer that developed angiosarcoma in the irradiated field from 1990 to 2009. Of these, 31 underwent surgery and were included for analysis. Angiosarcoma developed after median 7 years (range 3-25 years). R0 resection was obtained in 23 of 31 patients after primary treatment. Local recurrence developed in 19 patients after median 6 months (range 1-89 months). Regional and distant metastases occurred in 13 patients after median 17 months (range 2-50 months); nine which also had local recurrence. Patients whose local recurrence could be operated on had a better survival after treatment than those who were not considered for surgical treatment, median 34 months (range 6-84 months) compared with 6 months (range 5-24 months). The median disease-free survival and disease-specific survival was 16 and 37 months, respectively. Despite R0 resection, two-thirds of the patients developed a local recurrence. Survival among those with local recurrence was better if the patient could be treated with surgery. Overall, the prognosis was dismal and median DSS was just over 3 years

Prognostic value of proliferation in pleomorphic soft tissue sarcomas: a new look at an old measure.

Though proliferation has repeatedly shown a prognostic role in sarcomas, it has not reached clinical application. We performed a comprehensive evaluation of the prognostic role of 5 proliferation measures in a large series of soft tissue sarcomas of the extremities and the trunk wall. One hundred ninety-six primary soft tissue sarcomas of the extremities and the trunk wall were subjected to DNA flow cytometry for quantification of S-phase fraction and to immunohistochemical evaluation of Ki-67, Top2a, p21, and p27Kip1. In univariate analysis, positive expression of Ki-67 (hazard ratio = 4.5, CI = 1.6-12.1), Top2a (hazard ratio = 2.2, CI = 1.2-3.5) and high S-phase fraction (hazard ratio = 1.8, CI = 1.2-3.7) significantly correlated with risk for metastasis. When combined with currently used prognostic factors, Ki-67, S-phase fraction and Top2a fraction contributed to refined identification of prognostic risk groups. Proliferation, as assessed by expression of Ki-67 and Top2a and evaluation of S-phase fraction and applied to statistical decision-tree models, provides prognostic information in soft tissue sarcomas of the extremity and trunk wall. Though proliferation contributes independently to currently applied prognosticators, its role is particularly strong when few other factors are available, which suggests a role in preoperative decision-making related to identification of high-risk individuals who would benefit from neoadjuvant therapy

Hyperthermic isolated limb perfusion, preoperative radiotherapy, and surgery (PRS) a new limb saving treatment strategy for locally advanced sarcomas

BACKGROUND: This feasibility study presents the results of a new intensive treatment regimen for locally advanced extremity soft tissue sarcomas (ESTS), consisting of hyperthermic isolated limb perfusion (HILP), preoperative external beam radiotherapy (EBRT), and surgical resection. METHODS: From 2011 to 2016, 11 high grade locally advanced ESTS patients underwent this treatment regimen. Preoperative EBRT (12 × 3 Gy) started <4 weeks following the HILP (TNF-α and melphalan) and the surgical resection was planned to take place <2 weeks following the end of the EBRT. RESULTS: All patients completed the treatment. After a median follow-up of 32 (23-50) months, the limb was saved in 10 patients (91%), 1 patient (9%) developed a local recurrence, 5 patients (45%) developed distant metastases, and 3 patients (27%) died of their disease. During follow-up two patients (18%) developed a pathologic fracture of the treated limb and three patients (27%) developed a major wound complication requiring surgical intervention. The median overall treatment time (OTT) was 56 (49-69) days. CONCLUSIONS: This intensive treatment regimen is feasible and safe in locally advanced ESTS, and it achieves oncological results that are comparable with conventional HILP treatment. In addition, the major wound complication risk is comparable and the OTT is reduced
