Lawless A, Zhou DDX, McDonough J, Lo H, Mar J, Lazarakis S, Ward I, Connor J, Thompson SR, Coker D, Johnston A, Gyorki DE, Hong AM. The role of radiation therapy in the management of primary retroperitoneal sarcoma: A systematic review and clinical practice guidelines from the Australia and New Zealand Sarcoma Association. Cancer Treat Rev 2023; 120:102620. [PMID: 37657126 DOI: 10.1016/j.ctrv.2023.102620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 08/25/2023] [Accepted: 08/28/2023] [Indexed: 09/03/2023]
Abstract
While surgery is the mainstay of treatment for localised retroperitoneal sarcoma, the use of radiotherapy (RT) remains controversial. This systematic review aimed to evaluate the role of RT for retroperitoneal sarcoma. A systematic review using the population, intervention, comparison, and outcome model from 1990 to 2022 identified 66 studies (a mixture of preoperative and postoperative RT); one randomised controlled trial (RCT) with two publications, 18 registry studies, and 46 retrospective studies. In the RCT of preoperative RT, there was no difference in local/abdominal recurrence. The pooled analysis of this RCT and a retrospective study showed a significant abdominal recurrence free survival benefit with preoperative RT in low grade liposarcoma. The RCT and the majority of retrospective series found RT did not improve recurrence free survival (11 of 16 no difference in combined local and distant RFS, 11 of 13 no difference in distant metastasis free survival), disease specific survival (9 of 12 studies) or overall survival (33 of 49 studies). The majority of studies found no association between RT and perioperative morbidity. In summary, preoperative RT may improve local control for low grade (well-differentiated or grades 1-2 dedifferentiated) liposarcoma, but not other histological subtypes. There is no strong evidence that perioperative RT provides an overall survival benefit. Patients with low grade retroperitoneal liposarcoma can be considered for preoperative RT to improve abdominal recurrence free survival. The rationale and level of evidence in this scenario should be carefully discussed by the multidisciplinary team with patients. RT should not be routinely recommended for other histological subtypes.

Abstract
Canine Soft Tissue Sarcoma (STS) cell line A-72 has been largely employed for antiviral and antiproliferative studies. However, there are few information on their characteristics. Our aim was to evaluate A-72 expression level of genes and proteins involved in the innate immune response and cell cycle, their ability to respond to infective stressors and their possible use as a cellular model for anti-cancer studies in human and animal medicine. For this purpose, we evaluated the basal expression of immune-related, cell cycle and DNA repair genes on this cell line and tumoral tissues. A-72 ability to respond to a wild-type strain of Salmonella typhimurium was assessed. S. typhimurium showed ability to penetrate A-72 causing pro-inflammatory response accompanied by a decrease of cell viability. IL10 and IL18 genes were not expressed in A-72 while CXCL8, NOS2, CXCR4 and PTEN were highly expressed in all samples and TP53 was slightly expressed, as shown in human STS. Our results outline the ability of A-72 to respond to a bacterial agent by modifying the expression of important genes involved in innate immune response and provide a useful model for in vitro evaluation of new therapeutic approaches that could be translated into the human oncology.

Abstract
The incidence of leiomyosarcomas (LMS) has declined drastically. In fact, the introduction of immunohistochemistry (IHC) helped to differentiate LMS from other gastrointestinal stromal tumors (GIST) by receptor tyrosine kinase (KIT)-mutation detection making gastric LMS a sporadic tumor recently. We report a 60-year-old female who presented with a three-week history of abdominal pain. An abdominal computed tomography scan showed a large exophytic mass (22 ×19 ×15 cm) arising from the greater curvature of the stomach with multiple metastases. A biopsy was taken, and the initial histopathological examination was suggestive of GIST. However, further histopathological examination confirmed a high-grade gastric LMS. The patient refused any surgical intervention. Therefore, the patient had only received chemotherapy. On 9-month follow-up, the patient is still alive without disease progression. In conclusion, gastric LMS is a rare tumor. Due to the possibility of being misdiagnosed with other GIST, extensive pathological evaluation through specialized experts and IHC analysis is recommended.

Abstract
Retroperitoneal sarcomas are heterogeneous tumours with variable disease biology and outcomes. The prognosis is primarily related to tumour histology and grade as well as the ability to achieve margin negative resection. Surgery involves compartment or contiguous organ resection to achieve the above goal. Careful utilization of neoadjuvant and adjuvant strategies like radiotherapy and/or chemotherapy can lead to improvement in margin status, thereby contributing to better local control and possibly reducing systemic dissemination. Use of targeted therapies has paved newer pathways of treatment integration centred on molecular and genetic targets. The aim of this review is to update the reader on all aspects of retroperitoneal sarcoma management including emphasis on pertinent and landmark trials in this regard.

Analysis of the Effect of Tumor-Grade Change on the Prognosis of Retroperitoneal Sarcoma. Cancers (Basel) 2022; 14:cancers14123020. [PMID: 35740685 PMCID: PMC9221304 DOI: 10.3390/cancers14123020] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Revised: 06/13/2022] [Accepted: 06/18/2022] [Indexed: 12/10/2022] Open
Abstract
Simple Summary Changes in tumor differentiation have been observed during local recurrence in retroperitoneal sarcoma (RPS), and these changes have been reported to affect prognosis. However, the change in the tumor grade from the primary tumor to the first local recurrence, and the effect of this change on long-term outcomes, are unknown. This study reports the presence of tumor-grade changes and their effect on patient prognosis. While the grade changes did not affect the patient’s prognosis, a high grade of the primary tumor was an important factor. In addition, the risk factor for second local recurrence was a high grade of the recurrent tumor. Although this finding cannot change the treatment plan for recurrent RPS, it can provide the details of nomograms to predict the patient prognosis. Abstract In retroperitoneal sarcoma (RPS), the change in the tumor grade from the primary tumor to the first local recurrence, and the effect of this change on prognosis, are unknown. The aim of this study is to analyze whether these changes affect the prognosis of RPS. Patients who underwent surgery for a first locally recurrent RPS at Samsung Medical Center from January 2001 to February 2020 were included. The pathologic features of primary and recurrent tumors were compared, and the outcomes were measured. A total of 49 patients were investigated. There were 25 patients with different grades of primary and recurrent tumors. The improving, stable, and worsening groups contained 16 (32.7%), 24 (49%), and 9 (18.3%) patients, respectively. There was no significant difference in the prognosis between the three groups. In the analyses of the factors that affect the OS, a high grade of the primary tumor (p = 0.023) and the size of the recurrent tumor (p = 0.032) were statistically significant in both univariate and multivariate analyses. In a factor analysis of the second LR, a high-grade recurrent tumor (p = 0.032) was the only significant factor. There were tumor-grade changes between the primary tumor and recurrent tumor in RPS. However, the most important factor in prognosis is a high grade of the primary tumor.

Abstract
Soft tissue sarcomas are heterogeneous group of neoplasms making up to 1% of all malignant tumors in the adult population. The tumor generally appears on the extremities near large joints of middle-aged patients, especially in the popliteal fossa. Our patient presented in February 2014 due to a slowly enlarging, darker-colored swelling in the left popliteal fossa. Upon physical examination, a somewhat nodular, immobile, tender subcutaneous mass was observed. There was no locoregional lymphadenopathy. Patohistological findings showed a high-grade primary malignant mesenchymal tumor, biphasic synovial sarcoma type. The patient underwent surgery with wide surgical excision, followed by radiotherapy treatment. Magnetic resonance imagining follow up after one year revealed tumor recurrence. Neurovascular bundle involvement was detected, but without adjacent bone and muscular invasion and above-the-knee partial amputation of the left leg was performed. The intervention resulted in a remission of the neoplastic process and the patient was scheduled for regular check-ups. Broad surgical resection of the tumor with negative margins was the primary treatment in this case. Mutilating operations are necessary when anatomical structures around the tumor do not allow complete reintervention.

Abstract
INTRODUCTION Primary intravenous leiomyosarcomas are rare vascular tumors with aggressive disease biology. The diagnosis and management have been challenging as little data exist from large databases. METHODS A literature search was done to identify all cases of primary leiomyosarcomas in the last five years. Clinicopathological features and management strategies were evaluated. RESULTS The median age was 53 years, predominantly females (2.5:1), presenting as metastases in up to 12.1% cases. Most tumors were locally advanced with a median size of 10cm. Inferior vena cava involvement from renal veins to infrahepatic veins remains the most frequent site (57.1%cases) while nearly half (52.8%) proceeded for surgery without histological proof. Most patients could undergo upfront resection (88.0%) with few patients receiving neoadjuvant chemotherapy (4.3%) or neoadjuvant radiotherapy (2.2%). Significant multivisceral resections included right nephrectomy (41.3%), liver resection (25.7%) and left nephrectomy (2.2%). Most patients (91.8%) needed an inferior vena cava graft placement with remarkable microscopically negative margins (85.5% cases). Doxorubicin and ifosfamide were the most frequently used combination chemotherapy regimens in both pre and postoperative settings with partial responses. The median overall and disease free survival among operated patients was 60 months and 28 months respectively. In multivariate analysis large tumor, extensive inferior vena cava involvement, and need for adjuvant chemotherapy appeared significant predictors for overall survival. CONCLUSIONS Aggressive upfront surgical resection with clear margin remains the key for long-term survival. Doxorubicin-based regimens were preferred as neoadjuvant chemotherapy while adjuvant treatment with chemotherapy, radiotherapy, or both may be considered in high-risk patients.

Abstract
Soft tissue sarcomas (STS) constitute a heterogeneous group of rare solid tumors associated with significant morbidity and mortality. The evaluation and treatment of STS require a multidisciplinary team with extensive experience in the management of these types of tumors. National and international clinical practice guidelines for STS do not always provide answers to a great many situations that specialists have to contend with in their everyday practice. This consensus provides a series of specific recommendations based on available scientific evidence and the experience of a group of experts to assist in decision-making by all the specialists involved in the management of STS.

Abstract
INTRODUCTION In retroperitoneal soft tissue sarcoma (STS) local recurrence (LR) rates remain high despite more aggressive surgical approaches. Since wide resection margins cannot be achieved in all patients, application of intraoperative radiation therapy (IORT) has been frequently discussed. Still, the significance of IORT in multimodal treatment of retroperitoneal STS remains unclear. MATERIAL AND METHODS Patients undergoing resection of primary or recurrent retroperitoneal STS at the University of Heidelberg Department of General, Visceral and Transplantation Surgery were retrospectively analyzed. Univariate Kaplan-Meyer and multivariate Cox regression analyses were performed to identify predictors of LR-free survival and to investigate the impact of IORT and high cumulative radiation doses. Analyses with propensity-score matched subgroups for IORT and cumulative radiation dose were performed to control for selection bias. Subgroup analyses for patients with retroperitoneal liposarcoma were likewise performed. RESULTS 272 patients were identified. Recurrent tumors, histology of dedifferentiated liposarcoma or unclassified sarcoma and microscopically incomplete resection were associated with decreased LR-free survival. In liposarcoma, only recurrent and dedifferentiated tumors were confirmed as poor prognostic factors concerning LR. IORT and cumulative radiation doses exceeding 60 Gy did not influence LR rates (estimated 5-year LR-free survival: IORT: 39%, non-IORT: 46%; p = 0.79). CONCLUSION In this retrospective evaluation, additional application of IORT does not significantly influence oncological outcome in retroperitoneal soft tissue sarcoma. Randomized trials are needed to clarify the benefit of IORT.

Abstract
STUDY DESIGN Retrospective survival analysis of 44 undifferentiated high grade pleomorphic sarcoma (UPS) of the spine. OBJECTIVE To identify factors related to overall survival (OS) and help decision making in the treatment of undifferentiated high grade pleomorphic sarcoma of the spine. SUMMARY OF BACKGROUND DATA UPS is an aggressive malignant tumor rarely originating from the spine. Due to its scarcity, only a few studies had been reported to describe the clinical features, treatments, and outcomes of sporadic cases, devoid of evaluation on prognostic factors. METHODS Enrolled in this survival analysis were 44 patients who underwent surgery and adjuvant therapies from January 1999 to December 2015. Kaplan-Meier methods were applied to estimate the overall survival. A multivariate Cox algorithm was applied to recognize factors independently associated with overall survival. RESULTS Multivariate analysis suggested that age greater than or equal to 55 years (hazard ratio [HR], 3.923, P < 0.001), Eastern Cooperative Oncology Group (ECOG) score four (HR, 4.656, P < 0.001), and subtotal resection or piecemeal total resection (HR, 4.375, P < 0.001) were independently associated with poor overall survival. CONCLUSION We identified independent prognostic factors of UPS of the spine. Subtotal resection or piecemeal total resection, age more than or equal to 55 years and ECOG score four are factors adversely affecting overall survival of patients with UPS of the spine. LEVEL OF EVIDENCE 4.

Exp Ther Med 2018; 17:888-894. [PMID: 30651877 DOI: 10.3892/etm.2018.7013] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2018] [Accepted: 11/11/2018] [Indexed: 12/11/2022] Open
Abstract
The number of elderly patients with sarcoma (65 years or older) has increased with the rise in the aging of society. As it is difficult to treat elderly sarcoma patients in the same manner as younger patients, the present study sought to compare treatment options currently available for elderly patients. The present study was comprised 34 Japanese patients (21 men and 13 women) with malignant bone or soft tissue tumors who underwent surgery in our department from September 2004 to March 2014. The median patient age was 72 years (range, 65-86 years). Histologically, 23 cases were categorized as high-grade and 11 as low-grade. Treatments included surgery with adequate margins (25 cases), surgery with inadequate margins and radiotherapy (4 cases), surgery with inadequate margins and chemotherapy (3 cases) and intralesional resection (2 cases). The postoperative follow-up period ranged from 7 to 112 months (average, 49 months). The 5-year survival rates were determined and compared using the Kaplan-Meier method and log-rank test, respectively. Eastern Cooperative Oncology Group Performance Status (ECOG-PS) and Anesthesiologists-Physical Status (ASA-PS) scores were also determined. The overall 5-year survival rate was 86.02%; it differed significantly between patients with high-grade (100%) vs. low-grade (74.3%) neoplasms P<0.001), but not between patients aged 65-69 (76.9%) vs. ≥70 (90.2%) years-old (P=0.65). Tumor status was classified as follows: i) Continuously disease-free, n=24 cases; ii) alive with disease, n=3 cases; iii) and dead of disease, n=7 cases. The ECOG-PS status scores were 0 in 9 cases, 1 in 21 cases, and 2 in 4 cases. ASA-PS scores were also I in 9 cases and II in 23 cases. Thus, the primary treatment for elderly patients with sarcoma should be surgery alone as no additional benefits were obtained when radiotherapy or chemotherapy was also performed. Adequate margins should be confirmed along with the histology of surgical specimens.

Intraoperative radiation therapy for the treatment of recurrent retroperitoneal and pelvic tumors: a single-institution analysis. Radiat Oncol 2018; 13:224. [PMID: 30454036 PMCID: PMC6245634 DOI: 10.1186/s13014-018-1168-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2018] [Accepted: 10/30/2018] [Indexed: 12/30/2022] Open
Abstract
Background Patients with recurrent retroperitoneal and pelvic region tumors often require multimodal therapies. Intraoperative radiation therapy (IORT) can deliver high-dose radiation to tumor beds, even if first-line external beam radiation therapy (EBRT) was administered. We evaluated local control (LC) and survival in patients receiving IORT for recurrent tumors. Methods We retrospectively analyzed 41 patients with isolated pelvic or retroperitoneal recurrences of colorectal, gynecological, or retroperitoneal primary tumors. Following salvage surgery, all patients underwent tumor bed IORT via electron beam or high dose rate brachytherapy. Isolated IORT (median dose: 15 Gy) was administered to patients who had received first-line EBRT; other patients received IORT (median dose 12 Gy) plus EBRT. Local (LF), regional (RF), and distant failures (DF) were evaluated, and the Kaplan–Meier method and log-rank test were used to evaluate and compare overall survival (OS) from the date of IORT. Results Forty-one patients underwent 44 treatments, including 27 (61.3%) isolated IORT and 17 (38.7%) IORT and EBRT combination regimens. The median follow-up was 8.1 years (range: 4.4–11.7 years), and the 2, 5, and 8 year overall LC rates were 87.9, 64.0, and 49.8%, respectively. Regarding resection status, the respective 2, 5, and 8 year LC rates were 90, 76, and 76% for R0 resection and 75, 25, and 0% for R1 resection (p < 0.001). The 2, 5, and 8 year OS rates were 68, 43, and 26%, respectively. OS was better among patients with LC (p < 0.001). Twenty-four patients (58.5%) experienced a DF, and the 5 year OS rates for the patients with and without DF were 36 and 52%, respectively (p = 0.04). In a multivariate analysis, LF (p = 0,012) and recurrent retroperitoneal sarcoma (p = 0,014) were identified as significant predictors of worse OS. Thirteen patients (31%) developed clinically treatable complications related to IORT. Conclusions Many patients achieve long-term OS and LC without significant morbidity after salvage surgery and IORT, especially in case of clear margins.

Radiation-Induced Sarcoma following Prolonged Coronary Stent Placement. Case Rep Surg 2018; 2018:2903801.

Abstract
Radiation exposure for the average coronary stent placement varies based on a number of factors but typically amounts to 6-11 mSv per patient (compared to 3 mSv background). As with all procedures which utilize radiation, there is an inherent risk of genetic mutation and the possible development of malignancy. Here, we present the case of a 75-year-old male who presented with an exophytic mass on his back following prolonged coronary catheterization with a radiation burn seven years prior. Biopsy of the lesion revealed the mass was consistent with an undifferentiated pleomorphic sarcoma emanating from the site of the radiation burn. After staging studies demonstrated no evidence of metastatic disease, radical excision with negative margins was performed. This case demonstrates that despite the rarity of radiation injury, each incidence necessitates strict monitoring of radiation exposure and continual follow-up due to the risk of malignancy.

Jpn J Clin Oncol 2018; 48:799-805.

Abstract
Background We hypothesized that survival varied significantly between retroperitoneal soft tissue sarcoma (STS) and extremity/trunk STS. This study explored the reasons for the different outcomes and identified patient characteristics for survival. Methods This retrospective study identified 213 consecutive patients with localized primary STS from January 2002 to July 2013, including 47 retroperitoneal STS (22.1%) and 166 extremity/trunk STS (77.9%). Local failure-free survival (LFFS), distant metastasis-free survival (DMFS) and overall survival (OS) were constructed by the Kaplan-Meier method. Univariate Cox proportional hazards regression models were fit to assess the ability of patient characteristics to predict survival. Results At presentation, patients with retroperitoneal STS had larger tumor size (median size 18 cm vs. 6 cm; P < 0.001) and positive margin (21.3% vs. 8.4%; P = 0.014), and less often received radiotherapy (2.1% vs. 45.8%; P < 0.001). The median follow-up time for the entire population was 68 months (range, 5-127 months). Local recurrence was more frequent in patients with retroperitoneal STS compared with patients with extremity/trunk STS (53.2% vs. 28.3%; P = 0.001). LFFS and OS were lower in patients with retroperitoneal STS than extremity/trunk STS, with 5-year LFFS (50% vs. 74.3%; P < 0.001) and 5-year OS (65.4% vs. 77.5%; P = 0.017), respectively. Conclusion Retroperitoneal STS was associated with significantly worse survival compared with extremity/trunk STS. Larger tumor size, more patients with positive margin and fewer patients received radiotherapy in retroperitoneal group may result in worse survival compared with extremity/trunk disease.

Conception and Management of a Poorly Understood Spectrum of Dermatologic Neoplasms: Atypical Fibroxanthoma, Pleomorphic Dermal Sarcoma, and Undifferentiated Pleomorphic Sarcoma. Curr Treat Options Oncol 2018; 18:50. [PMID: 28762020 DOI: 10.1007/s11864-017-0489-6] [Citation(s) in RCA: 53] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/11/2023]
Abstract
OPINION STATEMENT Atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS) tumors share many clinical, etiologic, and histologic features and likely represent components of a tumor spectrum. In dermatologic oncology, differentiating between AFX and PDS is pivotal as tumors with histological features consistent with PDS are more likely to behave in a clinically aggressive manner. Importantly, the term "pleomorphic dermal sarcoma" (PDS) is a more appropriate designation than "undifferentiated pleomorphic sarcoma" (UPS) for describing deeper, more aggressive, histologically high-grade cutaneous tumors that otherwise resemble AFX. Surgery remains the gold standard for treatment. In the setting of AFX, excision with the Mohs micrographic technique appears to offer superior tumor control rates while maintaining greater tissue preservation over wide local excision and should be considered first line. In the setting of PDS, optimal management is less clear given the paucity of available data. However, due to its greater propensity to recur and metastasize, extirpation with complete tumor margin control appears paramount. The roles of imaging and SLNB in management and clinical outcomes of AFX and PDS are unclear given the lack of available data. In reality, these tools are unlikely to be helpful in most cases of AFX. However, in the setting of PDS, emerging literature indicates that these tumors are inherently higher risk, and thus, imaging and SLNB may be helpful in select cases. Additionally, radiation therapy may be of adjuvant benefit for these tumors when clear surgical margins cannot be obtained. While traditional chemotherapy has been largely ineffectual, the recent discovery of key oncogenetic mutations has allowed for the identification of several potential molecular drug targets that may have a therapeutic role with future study. In the unfortunate setting of metastatic disease, a multidisciplinary approach is optimal. Further studies are needed to establish definitive conclusions regarding risk stratification and best management practices.

Abstract
Chest wall contains a wide array of tissues ranging from soft tissues like skin and muscle to bone. A variety of sarcomas can present with a painful or painless mass, which often requires histological testing for diagnosis. Chest wall sarcomas are very rare entities which are often growing slow . A multidisciplinary team is necessary for the management of chest wall sarcomas. We present a case of a 30-year-old male with spindle cell sarcoma of the chest wall and he underwent wide local excision along with surgical reconstruction.
