Retroperitoneale Sarkome: Diagnostik und Therapie

2006

Background Due to the fact that there are no distinct anatomical compartments, retroperitoneal sarcomas are moreover diagnosed with evidence of large tumors and infiltration of adjacent organs. In spite of improvement of the diagnostic facilities and surgical techniques, quite frequently local recurrences with unfavourable prognosis turn up even after complete removal. It was the aim of this study to analyze diagnosis, therapy and long-term prognosis in patients with retroperitoneal sarcomas over a period of 10 years. Patients and methods Between January 1995 and January 2005, 379 patients underwent surgery for a primary retroperitoneal tumor at our clinic. Among the 67 (17.1 %) malignant l…

Nilotinib as Coadjuvant Treatment with Doxorubicin in Patients with Sarcomas: A Phase I Trial of the Spanish Group for Research on Sarcoma

2018

Abstract Purpose: Nilotinib plus doxorubicin showed to be synergistic regarding apoptosis in several sarcoma cell lines. A phase I/II trial was thus designed to explore the feasibility of nilotinib as coadjuvant of doxorubicin by inhibiting MRP-1/P-gp efflux activity. The phase I part of the study is presented here. Patients and Methods: Nilotinib 400 mg/12 hours was administered in fixed dose from day 1 to 6, and doxorubicin on day 5 of each cycle. Three dose escalation levels for doxorubicin at 60, 65, and 75 mg/m2 were planned. Cycles were repeated every 3 weeks for a total of 4 cycles. Eligible subtypes were retroperitoneal liposarcoma, leiomyosarcoma, and unresectable/metastatic high-g…

Treatment of soft tissue sarcoma in childhood and adolescence: A report of the german cooperative soft tissue sarcoma study

1992

Background In the first German soft tissue sarcoma (STS) study, CWS-81, 344 patients younger than 19 years of age who had previously untreated soft tissue sarcoma were studied. For this analysis, there were 218 patients with chemosensitive STS (Group A: rhabdomyosarcoma [RMS], synovial sarcoma, extraosseous Ewing sarcoma, leiomyosarcoma, undifferentiated sarcoma, and malignant peripheral neuroectodermal tumor) who could be studied for a minimum potential follow-up time of 6 years. Methods A staging system based on the postoperative extent of the disease was used. The chemotherapy for Stage I-III disease consisted of vincristine, dactinomycin, cyclophosphamide, and doxorubicin (VACA). Patien…

Impact of Chemotherapy in the Adjuvant Setting of Early Stage Uterine Leiomyosarcoma: A Systematic Review and Updated Meta-Analysis

2020

Background: Although the use of adjuvant chemotherapy (AC) appears to be increasing over the past few years, several clinical trials and previous meta-analyses failed to determine whether AC could improve clinical outcomes in uterine leiomyosarcoma (uLMS). The aim of this systematic review and meta-analysis was to compare AC (with or without radiotherapy) versus observation (obs) after primary surgery in early stage uLMS. Materials and Methods: Randomized controlled (RCTs) and non-randomized studies (NRSs) were retrieved. Outcomes of interest were as follows: distant recurrence rate, locoregional recurrence rate and overall recurrence rate. Results about distant recurrence rate, locoregiona…

Surgical treatment of pulmonary artery sarcoma

2001

Abstract Objective: Pulmonary artery sarcomas are rare and usually fatal tumors. The diagnosis is difficult and delayed in most cases. Newer imaging techniques could allow early diagnosis in patients with symptoms of pulmonary vascular obstruction. Surgical resection improves clinical symptoms and offers the only chance of cure. We report the case histories of 7 patients with primary pulmonary artery sarcomas treated by surgical resection with or without adjuvant therapy. Methods: Seven patients (3 women and 4 men; mean age, 52.3 years; preoperative New York Heart Association functional class III/IV, n=5/2) underwent operations. Malignancy was preoperatively suspected in 5 patients, and 2 p…

Pulmonary metastasectomy in soft tissue sarcomas: a systematic review

2021

Background Soft tissue sarcoma (STS) tend to metastasis to the lungs. Pulmonary metastasectomy seems to be a common practice always when plausible. The objective of this article was to review systematically the results of a literature search on pulmonary metastasectomy for STSs published in the last ten years and to offer a brief overview about the current practice as well. Methods Eight retrospective studies published in the period 2010-2020, which included patients with pulmonary metastases and metastasectomy were selected. Indication for surgery, survival rate and factors influencing survival were the primary outcomes, while further interesting findings in the studies were also collected…

Resection of a giant mediastinal leiomyosarcoma

2019

ABSTRACT Primary leiomyosarcomas of the lung are rare tumors. We report a case of 49-year-old female with history of cough, breathless at rest, right sided chest pain. Chest CT showed a huge (16 cm) mediastinal mass located on the right mediastinum encasing the right main pulmonary artery and infiltrating the main right bronchus and pericardium. The tumor was resected with combined pericardiectomy and pnemonectomy via hemiclamshell incision. This surgical access provided an adequate exposure of the chest “blind zones” and it allowed a radical and safe surgical resection of lung, pleura, pericardium and diaphragm. The final diagnosis showed a low grade differentiation leiomyosarcoma.

An Extremely Rare Case of Disseminated Peritoneal Leiomyomatosis with a Pelvic Leiomyosarcoma and Omental Metastasis after Laparoscopic Morcellation:…

2022

Minimally invasive treatment of uterine fibroids usually requires a power morcellation, which could be associated with several complications. A rare sequela is disseminated peritoneal leiomyomatosis. Indeed, recurrence or metastasis in these cases could be attributed to iatrogenic or under-evaluation of primary tumors, although a subset of cases is a sporadic sample of biological progression. We present an extremely rare case of a patient who underwent laparoscopic morcellation and after 12 years developed a pelvic leiomyosarcoma with two omental metastases, disseminated peritoneal leiomyomatosis with a parasite leiomyoma with bizarre nuclei and a parasite cellular leiomyoma simultaneously.…
