Durable response to anti-PD-1 immunotherapy in epithelioid angiomyolipoma: a report on the successful treatment of a rare malignancy. J Immunother Cancer 2018; 6:97. [PMID: 30285856 PMCID: PMC6167873 DOI: 10.1186/s40425-018-0415-x] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2018] [Accepted: 09/18/2018] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Malignant angiomyolipoma is an uncommon tumor of the class of perivasciular epithelioid cell neoplasms (PEComas). These tumors are characteristically driven by deleterious mutations in the tumor suppressors TSC1 and TSC2, whose gene products typically act to inhibit mTOR. There are several cases of malignant angiomyolipoma which exhibit transient responses to mTOR inhibitors, forming the basis of current practice guidelines in malignant PEComa. However the tumors ultimately acquire resistance, and there is no well-established second-line option. Despite the increasing prevalence of immunotherapy across a wide range of solid tumors, little is known about the immune infiltrate and PD-L1 expression of angiomyolipoma. Furthermore, there is no reported case on the treatment of malignant angiomyolipoma with an immune checkpoint inhibitor. CASE PRESENTATION A 38 year-old man presented with gross hematuria and was diagnosed with renal epithelioid angiomyolipoma. Despite surgical resection, the tumor recurred and metastasized. Targeted genomic sequencing revealed a deleterious mutation in TSC2, and the patient was treated with the mTOR inihbitor everolimus. The patient went on to have a partial response but ultimately progressed. He was then treated with the anti-PD-1 immune checkpoint inhibitor nivolumab, and achieved a durable near-complete response which is ongoing after two years of treatment. Immunohistochemical staining of tumor tissue revealed strong PD-L1 expression and a brisk T-cell infiltrate. CONCLUSIONS We report on the first durable systemic treatment of malignant epithelioid angiomyolipoima with the use of PD-1 antibody nivolumab. Given the absence of prospective clinical trials in this exceedingly rare disease, particularly in the second-line setting, immune checkpoint inhibitors like nivolumab should be considered.

Abstract
Leiomyosarcoma is a malignant neoplasm that shows smooth muscle differentiation. It is the second most common sarcoma to affect the retroperitoneum. Retroperitoneal leiomyosarcomas may grow to large sizes before detection and may be an incidental finding at imaging. When symptomatic, retroperitoneal leiomyosarcoma may cause compressive symptoms, including pain. Retroperitoneal leiomyosarcoma most commonly manifests as a large soft-tissue mass, with areas of necrosis. The most frequent pattern of growth is an entirely extravascular mass. Less commonly, leiomyosarcoma may demonstrate both extravascular and intravascular components. Rarely, retroperitoneal leiomyosarcomas are completely intravascular, typically arising from the inferior vena cava. Given its variable imaging features, a large variety of neoplastic and nonneoplastic conditions are included in the differential diagnosis of retroperitoneal leiomyosarcoma. In this review, the authors discuss retroperitoneal leiomyosarcoma, with emphasis on the pathologic basis of disease, and illustrate the multimodality imaging appearances of retroperitoneal leiomyosarcoma using cases from the Radiologic Pathology Archives of the American Institute for Radiologic Pathology. The authors review important differential considerations of retroperitoneal leiomyosarcoma, focusing on the extravascular pattern of growth, and emphasize clinical and imaging features that help radiologists differentiate leiomyosarcoma from the most frequent mimics. The information presented in this review will aid radiologists in fulfilling their key roles in the diagnosis, operative planning, and follow-up of patients with retroperitoneal leiomyosarcoma.

Abstract
BACKGROUND Uterine adenosarcoma with sarcomatous overgrowth (ASSO) is a rare and aggressive disease. A case of a 16-year-old girl with uterine ASSO is reported herein. The patient received surgical resection and chemotherapy and remained alive without disease 11 months after the surgery. CASE A 16-year-old girl was diagnosed with uterine ASSO, International Federation of Gynecology and Obstetrics (2009) stage I c. She underwent total abdominal hysterectomy, bilateral salpingectomy, and chemotherapy. She remains alive and there was no evidence of tumor recurrence on follow-up physical, laboratory, and ultrasound scan examinations. SUMMARY AND CONCLUSION Surgery is the primary treatment for uterine ASSO, total abdominal or laparoscopic-assisted vaginal hysterectomy with or without bilateral salpingo-oophorectomy are recommended. Early surgical resection might increase survival of uterine adenosarcoma. Long-term follow-up of the patients is recommended because of the high chance of recurrence.

Abstract
Imatinib has revolutionized the treatment of gastrointestinal stromal tumors (GIST); however, primary and secondary resistance to imatinib is still a major cause of treatment failure. Multiple mechanisms are involved in this progression. In the present study, we reported a novel mechanism for the acquired resistance to imatinib, which was induced by enhanced Ca2+ influx via stromal‐interacting molecule 1 (STIM1)‐mediated store‐operated Ca2+ entry (SOCE). We found that the STIM1 expression level was related to the acquired resistance to imatinib in our studied cohort. The function of STIM1 in imatinib‐resistant GIST cells was also confirmed both in vivo and in vitro. The results showed that STIM1 overexpression contributed to SOCE and drug response in imatinib‐sensitive GIST cells. Blockage of SOCE by STIM1 knockdown suppressed the proliferation of imatinib‐resistant GIST cell lines and xenografts. In addition, STIM1‐mediated SOCE exerted an antiapoptotic effect via the MEK/ERK pathway. The results from this study provide a basis for further research into potential novel therapeutic strategies in acquired imatinib‐resistant GIST.

Abstract
PURPOSE Primary tumor location has been identified as an important prognostic factor among patients with gastrointestinal stromal tumors (GISTs). The purpose of this study is to identify how primary tumor location may affect outcomes after resection for patients with metastatic GISTs. METHODS Patients with GISTs and distant metastases at diagnosis were identified in the Surveillance Epidemiology and End Results (SEER) database. Patients that underwent surgery were matched to patients that did not undergo surgery using propensity score matching (PSM) analysis. RESULTS After PSM, 570 patients were identified (males 334 [58.6%], females 236 [41.4%], age 62 ± 13.9 years). Gastric tumors constituted the majority (325 [57%]), followed by small intestinal (136 [23.9%]), colorectal (19 [3.3%]), and retroperitoneal/peritoneal tumors (23 [4%]). Median follow-up was 25.5 months (95% CI 23-29 months). Undergoing surgery was associated with improved disease-specific survival (DSS) on both univariate (median not reached vs. 51 months, p < 0.001) and multivariate analyses (HR 4.98, 95% CI 2.23-11.12, p < 0.001). A sub-analysis of patients with gastric GISTs showed that undergoing surgery was the only significant factor associated with improved DSS (median not reached vs. 39 months, p < 0.001, HR 2.95, 95% CI 1.92-4.53). In contrast, undergoing surgery was not associated with improved survival for small intestinal, colorectal, or retroperitoneal/peritoneal tumors. CONCLUSIONS Surgery for gastric metastatic GISTs is associated with improved survival. No discernible benefit after surgical resection was identified for patients with small intestinal, colorectal, retroperitoneal, or peritoneal metastatic GISTs.

Abstract
Rationale To assess the diagnostic value of 18F-FDG-PET/CT for different retroperitoneal soft tissue sarcomas (STS) and other similar tumors. To analyze the predictive value of 18F-FDG-PET/CT for histological grade and main prognostic factors. Methods 195 patients with 44 different diseases have been included. Relationship between SUVmax, Clinical, pathological, and prognostic information has been analyzed. Results Malignant tumors do not show higher SUVmax than benign ones (P=0.443). We divided all 44 different diseases into two groups; SUVmax of group 1 is significantly higher than group 2 (P ≤ 0.001). The ROC curve suggests 4.35 is the cutoff value to distinguish groups 1 and 2 (sensitivity = 0.789; specificity = 0.736). SUVmax correlates with Ki-67 index, mitotic count, vascular resection, histological grade, and recurrent STS without considering pathological diagnosis (P=0.001, P=0.012, P=0.002, P ≤ 0.001, and P=0.037, resp.). Conclusion 18F-FDG-PET/CT cannot simply distinguish malignant and benign tumors in retroperitoneal/intra-abdominal cavity; however, the SUVmax of malignant tumors, inflammatory pseudotumor, and PPGL group is higher than the SUVmax of benign tumors, lymph node metastasis, hematoma, and low malignant STS group. Guidance of "SUVmax location" may be helpful for biopsy and pathology dissection.

Abstract
In 2014, Joensuu and colleagues devised the first recurrence risk score (RRS) to identify the risk factors for gastrointestinal stromal tumor (GIST) recurrence. However, there are scarce data available on RRS effectiveness and efficiency. Therefore, we retrospectively analyzed clinical data to validate Joensuu's RRS in patients treated with adjuvant imatinib.In this retrospective cohort study, data were collected from patients with GIST who were treated with adjuvant imatinib between December 2005 and May 2017 in the West China Hospital. The study consisted of 137 patients, after application of inclusion and exclusion criteria. Recurrence-free survival (RFS) was the primary end point.The RRSs for 137 patients were divided into 3 groups: low (n = 46), medium (n = 48), and high (n = 43). The RFSs of the 3 groups were significantly different (P < .001). In patients who received adjuvant imatinib for <36 months, the RFS difference was also significant (P < .001), and the result was similar in patients treated with adjuvant imatinib for ≥36 months (P = .03). The area under the curve of the RRS was 0.84 ([95% confidence interval] 0.76-0.92, P < .001), suggesting that the RRS method could accurately assess recurrence risks for patients with GIST who were treated with adjuvant imatinib.It is appropriate to apply the RRS method to assess recurrence risks for patients with GIST who were treated with adjuvant imatinib. A longer adjuvant imatinib duration is recommended for high-risk patients with GIST. It is also important to identify a more effective treatment for patients who are resistant to imatinib.

Surgical Management of Gastric Gastrointestinal Stromal Tumours: Comparison of Outcomes for Local and Radical Resection. Gastroenterol Res Pract 2018; 2018:2140253.

Abstract
Gastrointestinal stromal tumours (GISTs) most commonly originate from the stomach. Their treatment is dependent on size and whether they are symptomatic. Curative treatment requires surgery, which may be preceded by neoadjuvant imatinib if it is felt that this will aid in achieving clear (R0) resection margins. The aim of this study was to evaluate outcomes from patients that underwent a "local" organ-preserving operation, with those that required a more radical resection, and the influences on selecting a more radical resection. A retrospective review of patients undergoing surgery for symptomatic gastric GISTs from a single institution over 9 years was carried out. Patients were divided into three cohorts dependent on whether they had a "local" resection, "anatomical" resection, or "extended" resection. 71 patients were included. Overall, 5-year survival was 92%. Operating time, blood loss, and length of stay were significantly lower in the group undergoing local resection (p < 0.05). Tumour size was also smaller in the local group (median 4 cm versus 5 cm p < 0.05). Tumour location also influenced the type of surgery performed, with tumours at the cardia, gastroesophageal junction, and antrum all having "anatomical" resections. Lymphadenectomy did not appear to impact on outcomes. These findings indicate that local excision, where possible, does not impair oncological outcomes.

Abstract
BACKGROUND Multi-institutional collaborations provide granularity lacking in epidemiologic data sets to enable in-depth study of rare diseases. For patients with superficial, high-grade soft tissue sarcomas of the trunk and extremity, the value of radiation therapy (RT) is not clear. We aimed to use the 7-institution US Sarcoma Collaborative (USSC) and the National Cancer Database (NCDB) to investigate this issue. STUDY DESIGN All adult patients with superficial truncal and extremity high-grade soft tissue sarcomas who underwent primary curative-intent resection from 2000 to 2016 at USSC institutions or were included in the NCDB from 2004 to 2013 were analyzed. Propensity score matching was performed. End points were locoregional recurrence-free survival (LRFS), overall survival (OS), and disease-specific survival (DSS). RESULTS Of 4,153 patients in the USSC, 169 patients with superficial high-grade tumors underwent primary curative-intent resection, 38% of which received RT. On multivariable Cox-regression analysis, RT was not associated with improved LRFS (p = 0.56), OS (p = 0.31), or DSS (p = 0.20). On analysis of 51 propensity score-matched pairs, RT was still not associated with increased LRFS, OS, or DSS. Analysis of 631 propensity score-matched pairs in the NCDB demonstrated improved 5-year OS rate associated with RT (80% vs 70%; p = 0.02). The LRFS and DSS rates were not evaluable. CONCLUSIONS Granular data afforded by collaborative research enables in-depth analysis of patient outcomes. The NCDB, although powered with large numbers, cannot assess many relevant outcomes (eg recurrence, DSS, or complications). In this study, the approaches yielded conflicting results. The USSC data suggested no value of radiation and the NCDB demonstrated improved OS, contradicting all randomized controlled trials in sarcoma. The pros and cons of either approach must be considered when applying results to clinical practice, and underscore the importance of randomized controlled trials.

Abstract
Background Desmoid-type fibromatosis is a benign mesenchymal neoplastic process. It exhibits an uncertain growth pattern and high recurrence rate. Previously radical surgical resection was the mainstay of treatment, but recently more surgeons are opting for conservative management with observation (“wait and see” policy). The authors intend to evaluate different therapeutic modalities and oncological outcomes for abdominal wall desmoid tumors. Methods We performed a retrospective study of patients who underwent surgical, hormonal or chemotherapy treatment for abdominal wall desmoid tumors between 1982 to 2014 at two institutions affiliated with the University of São Paulo, Brazil. Results In the study period, 32 patients were included. Twenty-seven patients had surgery upfront. Of those, 89% were women with a median age of 33 years. Mean tumor size was 10 cm. Pathology confirmed free margins in 92% of resections. Tumor recurrence rate was 11%, with median relapse-free survival being 24 months. Multivariate analysis showed that positive final margins (p < 0.001) and positive frozen section (p = 0.001) were independent predictors of recurrence. For the 5 patients who underwent pharmacological therapy, median age was 33 years and median tumor diameter before treatment was 13 cm. Four patients exhibited partial response by Response Evaluation Criteria in Solid Tumors (RECIST). The single patient who did not respond to RECIST underwent radiotherapy. Conclusion Desmoid tumor treatment has been evolving over the past decade towards a more conservative approach. Pharmacological treatment may result in tumor size regression. When surgical excision is indicated, positive margins represent an important prognostic factor for local tumor recurrence.

Predictors of lymph node metastasis in patients with gastrointestinal stromal tumors (GISTs). Langenbecks Arch Surg 2018; 403:599-606. [PMID: 29855800 DOI: 10.1007/s00423-018-1683-0] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2018] [Accepted: 05/24/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND Lymph node metastasis is not common among patients with gastrointestinal stromal tumors (GISTs) and its prognostic value is controversial. The purposes of this study are to identify predictors of lymph node metastasis and determine its prognostic associations. METHODS A retrospective analysis of the surveillance, epidemiology and end results (SEER) database was performed. Patients with GISTs that underwent surgery and pathologic nodal staging were identified. Logistic regression and Cox regression were performed to identify independent predictors and prognostic factors, respectively. RESULTS Of 1430 patients (age: 61.5 ± 14.5 years, 52% males), 140 (9.8%) had lymph node metastasis. On multivariable analysis, distant metastasis was the only independent predictor of lymph node metastasis (OR 4.95, 95% CI: 2.43-10.08, p < 0.001). In the entire cohort, lymph node metastasis did not reflect a worse overall survival (OS, HR 1.12, 95% CI: 0.49-2.58, p = 0.794) or disease-specific survival (DSS, HR 0.95, 95% CI: 0.31-2.88, p = 0.924), but was an independent predictor of worse OS in 51 patients (25.4% of 201 patients) who presented with both lymph node metastasis and synchronous distant metastasis (HR 2, 95% CI: 1.25-3.21, p = 0.004). Lymph node metastasis was also independently associated with worse survival among patients with small intestinal (OS: HR 1.88, 95% CI: 1.15-3.1, p = 0.013) and colorectal tumors (OS: HR 3.41, 95% CI: 1.56-7.46, p = 0.002, DSS: HR 3.58, 95% CI: 1.27-10.06, p = 0.016). CONCLUSIONS Metastatic disease is an independent predictor of lymph node metastasis in patients with GISTs. Lymph node metastasis is also associated with worse overall survival in patients with metastatic GISTs.

Combined Use of the Neutrophil-Lymphocyte and Platelet-Lymphocyte Ratios as a Prognostic Predictor in Patients with Operable Soft Tissue Sarcoma. J Cancer 2018; 9:2132-2139. [PMID: 29937932 PMCID: PMC6010672 DOI: 10.7150/jca.24871] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2018] [Accepted: 03/31/2018] [Indexed: 12/12/2022] Open
Abstract
Background: Preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are associated with poor prognosis in soft tissue sarcoma (STS). The aim of the present study is to determine whether the combination of NLR and PLR (CNP) can better predict patient survival after resection for STS. Methods: We included 310 STS patients in this retrospective study. Preoperative CNP was calculated as follows: patients with both elevated NLR (>2.51) and PLR (>191.1) were given a score of 2; patients showing an increase in one or neither were allocated a score of 1 or 0, respectively. Results: Cut-off values of 2.51 and 191.1 were defined as elevated NLR and PLR, respectively. Elevated CNP was significantly associated with older age (P=0.034), larger tumor size (P=0.025), deeper tumor location (P=0.044), higher tumor grade (P=0.028), a more advanced stage according to the American Joint Committee on Cancer (AJCC) (P=0.005), shorter overall survival (OS) (P=0.000) and shorter disease-free survival (DFS) (P=0.000). Multivariate analysis indicated CNP but not NLR or PLR to be an independent prognostic factor for OS and DFS (P=0.000 and P=0.001, respectively). Conclusions: Preoperative CNP is associated with tumor progression and can be considered an independent marker of postoperative survival in patients with STS.

Abstract
Adjuvant therapy of local soft tissue sarcomas (STS) after wide surgical excision still is a topic under controversial scientific debate. In this single center report we have offered an adjuvant “sandwich” therapy protocol consisting of 4 cycles of doxorubicin (75 mg/m2 i.v. over 1 h on day 1) followed by ifosfamide (5 g/m2 i.v. over 24 h starting on day 1) and local radiotherapy scheduled between chemotherapy cycles 2 and 3 to 104 consecutive patients after wide surgical excision (R0) of histologically proven high-grade STS. After a mean follow-up of 39 months (range 5–194 months) relapse free survival (RFS) at 2 and 5 years was 68.1% (95% CI, 58.5–77.7%) and 61.2% (95% CI, 50.4–71.6%). When analyzing the 82 STS cases of the extremities only 2- and 5-year RFS was 74.0% (95% CI, 64.0–84.0%) and 65.3% (95% CI, 53.7–76.9%). By intent-to-treat analysis, the overall survival (OS) at 2 years was 87.3% (95% CI, 80.5–94.1%) and 75.6% (95% CI, 65.2–86.0%) at 5 years, while OS for STS of the extremities only cohort was 90.5% (95% CI, 83.7–97.3%) and 79.0% (95% CI, 68.4–89.6%), respectively. Tolerability of the treatment was good. This analysis demonstrates the feasibility of adjuvant chemoradiotherapy and reflects the results of the long lasting intensive multidisciplinary team approach at our “high-volume” sarcoma center. The long-term survival in our patients is among the highest reported and the low local and distant recurrence rate in high-risk STS is at least comparable to the published data.

Abstract
Gastrointestinal stromal tumors (GISTs) are relatively common mesenchymal tumors. They originate from the wall of hollow viscera and may be found in any part of the digestive tract. The prognosis of patients with stromal tumors depends on various risk factors, including size, location, presence of mitotic figures, and tumor rupture. Emergency surgery is often required for stromal tumors with hemorrhage. The current literature suggests that stromal tumor hemorrhage indicates poor prognosis. Although the optimal treatment options for hemorrhagic GISTs are based on surgical experience, there remains controversy with regard to optimum postoperative management as well as the classification of malignant potential. This article reviews the biological characteristics, diagnostic features, prognostic factors, treatment, and postoperative management of GISTs with hemorrhage.

Abstract
BACKGROUND The role of surgical resection in the treatment of patients with metastatic/recurrent gastrointestinal stromal tumors (GIST) is unclear. The aim of this study was to identify preoperative factors associated with oncologic outcomes for recurrent/metastatic GIST after tyrosine kinase inhibitor (TKI) therapy. METHODS We identified 107 patients with metastatic or recurrent GIST treated with TKIs and surgical resection (2002-2012). Patients that underwent palliative or incomplete resection were excluded. Complete resection was achieved in 87 patients which comprise the analytic cohort. Univariate and multivariate analyses were conducted to identify risk factors for GIST-specific survival (DSS) and time-to-recurrence (TTR). RESULTS At a median follow-up of 51 months (91 months for survivors), median DSS was 74 months and TTR was 21 months. By univariate analysis, unifocal disease, duration of TKI < 365 days, and no evidence of radiographic progression were associated with improved TTR and DSS. Multivariate Cox regression demonstrated that evidence of radiographic progression was associated with shorter DSS (HR 2.53, 95%CI = 1.27-5.06, P = 0.008) and increased risk of recurrence (HR 3.33, 95%CI = 1.91-5.82, P < 0.001). CONCLUSIONS Patients with unifocal disease and radiographic evidence of response to TKI therapy may achieve improved oncologic outcomes when complete surgical resection is achieved following treatment with TKI.

Abstract
BACKGROUND Laparoscopic resection for gastric gastrointestinal stromal tumors (GISTs) is technically feasible, but the long-term effect remains uncertain. This study aims to compare the long-term oncologic outcomes of laparoscopic versus open resection of GISTs by larger cases based on tumor size-location-matched study. METHODS Between 2006 and 2015, 63 consecutive patients with a primary gastric GIST undergoing laparoscopic resection were enrolled in and matched (1:1) to patients undergoing open resection by tumor size and location. Clinical and pathologic parameters and surgical outcomes associated with each surgical type were collected and compared. RESULTS The operation time, intraoperative blood loss, return of bowel function and oral intake, nasogastric tube retention time and postoperative stay were all shorter/faster in laparoscopic group than those in open group (P < 0.001). Postoperative complications were comparable except for the higher incidence of abdominal/incision pain in open group (9.52 vs 27%, P = 0.01). There was no statistical difference in recurrence rate (9.52 vs 15.87%, P = 0.29) and long-term recurrence-free survival between the two groups (P = 0.39). CONCLUSIONS The long-term oncologic outcome of laparoscopic resection of primary gastric GISTs is comparable to that of open procedure, but laparoscopic procedure has the advantage of minimal invasion and is superior in postoperative recovery.

Risk Factors Including Age, Stage and Anatomic Location that Impact the Outcomes of Patients with Synovial Sarcoma. Med Sci (Basel) 2018; 6:medsci6010021.

Abstract
Synovial sarcoma is a high-grade soft tissue sarcoma that inflicts mostly children and young adults with high mortality rate; however, the risk factors that impact the outcomes remain incompletely understood. We have identified the synovial sarcoma cases from the Kaiser Permanente Northern California cancer registry between 1981 and 2014. Kaplan–Meier plots were used to display disease-free survival (DFS) and overall survival (OS); log-rank tests and Cox proportional hazard models were used to determine the impact of clinical factors on DFS, OS, and disease-specific survival. Tumor size > 5.0 cm and age > 50 years were associated with higher risk of presenting with stage IV disease. Median OS for patients with stage IV was 1.3 years and 7.8 years for early-stage disease. For patients with early-stage disease, tumor size > 5.0 cm was significantly associated with worse DFS, sarcoma-specific morality, and OS. Compared to extremity primary, patients with head and neck and trunk primary had approximately three-fold higher sarcoma-specific mortality and lower OS. There was no significant difference in DFS or OS among three histologic subtypes. Pre-operative and/or post-operative chemotherapy was not associated with improvement in DFS or OS. Twenty-six patients relapsed with predominantly lung metastasis, thirteen of whom received metastatectomy with a median OS of 7.8 years, compared to 2.3 years for patients who did not receive metastatectomy. In conclusion, age older than 50 years and tumor size > 5.0 cm are risk factors for presenting with stage IV disease. For early-stage patients, trunk and head and neck primary as well as tumor size > 5.0 cm are risk factors for decreased OS.

Abstract
Adjuvant radiotherapy is an important clinical treatment option for the majority of sarcomas. The motivation of current study is to identify a gene signature and to predict radiosensitive patients who are most likely to benefit from radiotherapy. Using the public available data of soft tissue sarcoma from The Cancer Genome Atlas, we developed a cross-validation procedure for identifying a gene signature and predicting radiosensitive patients through. The result showed that the predicted radiosensitive patients who received radiotherapy had a significantly better survival with a reduced rate of new tumor event and disease progression. Strata analysis showed that the predicted radiosensitive patients had significantly better survival under radiotherapy independent of histologic types. A hierarchical cluster analysis was used to validate the gene signature, and the results showed the predicted sensitivity for each patient well matched the results from cluster analysis. Together, we demonstrate a radiosensitive molecular signature that can be potentially used for identifying radiosensitive patients with sarcoma.

Abstract
Sarcomas are rare but malignant tumors with high risks of local recurrence and distant metastasis. Anti-angiogenic therapy is a potential strategy against un-controlled and not-organized tumor angiogenesis. We aimed to assess the safety and efficacy of apatinib, an oral tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor-2, in patients with advanced sarcoma. Thirty-one patients who received initial apatinib between September 2015 and August 2016 were retrospectively reviewed. Among them, 19 (61.3%) patients were heavily pretreated with two or more lines of cytotoxic chemotherapy. Apatinib was given at a start-dose of 425 mg qd. During therapy, 9 (29.0%) patients required dose interruption and 7 (22.6%) needed dose reduction, and the mean dosage of apatinib was 372.9 ± 68.4 mg/day. In the study cohort, one patient was treated as adjunctive therapy and 6 patients stopped treatment before radiographic response assessment. Thus, 24 patients were eligible for tumor response evaluation. The objective response rate was 33.3% and clinical benefit rate was as high as 75.0%. The progression free survival was 4.25 (95% confidence interval [CI], 2.22-5.11) months, whereas the overall survival was 9.43 (95% CI, 6.64-18.72) months. Compared with other histological subtypes, leiomyosarcoma did not show significant survival benefits. Most of the adverse events (AEs) were at grade 1 or 2. The main grade 3 AEs were hypertension (6.5%), hand foot skin reaction (6.5%), and diarrhea (3.2%). In conclusion, apatinib showed promising efficacy and acceptable safety profile in metastatic or recurrent sarcoma, giving rationale clinical evidence to conduct clinical trials.

Abstract
Background & Aims A significant benefit of imatinib adjuvant therapy for patients with high risk gastrointestinal stromal tumors (GIST) has been confirmed. However, the effect of imatinib adjuvant therapy for intermediate-risk GIST has not been well studied. In this article, we compare differences of recurrence-free survival (RFS) rates between patients with intermediate-risk GIST who accepted imatinib adjuvant therapy and those who did not. Method A retrospective study of intermediate-risk GIST was conducted in the First Affiliated Hospital of Zhengzhou University, China. The pathology reports of 112 patients who had been treated by surgery showed intermediate-risk GIST. The treatment and control groups were designed according to the administration of imatinib adjuvant therapy (≥1 year). Survival and recurrence data were collected and RFS of each group was calculated. Results Eighty fivepatients with intermediate-risk GIST were followed up. Thirty of them (treatment group) accepted imatinib adjuvant therapy over 1 year. Through comparing the RFS of the two groups, we established that there was no statistically significant difference in RFS rates (P=0.940). Conclusion There is no significant benefit for patients with intermediate-risk GIST to accept imatinib adjuvant treatment.

Abstract
Lartruvo® (olaratumab) is a fully human immunoglobulin G subclass 1 (IgG1) monoclonal antibody that inhibits platelet-derived growth factor receptor alpha (PDGFRα). The antitumor activity of olaratumab has been tested in vitro and in vivo, and inhibition of tumor growth has been observed in cancer cell lines, including glioblastoma and leiomyosarcoma cells. It represents the first-in-class antibody to be approved by regulatory authorities for the treatment of advanced soft-tissue sarcomas (STSs) in combination with doxorubicin, based on the results of the Phase Ib/II trial by Tap et al. The median progression-free survival (PFS), which was the primary end point of the study, was improved for patients treated with olaratumab plus doxorubicin compared to those treated with doxorubicin monotherapy (6.6 vs 4.1 months, respectively; HR 0.672, 95% CI 0.442-1.021, p=0.0615). Moreover, final analysis of overall survival (OS) showed a median OS of 26.5 months with olaratumab plus doxorubicin vs 14.7 months with doxorubicin, with a gain of 11.8 months (HR 0.46, 95% CI 0.30-0.71, p=0.0003). In October 2016, olaratumab was admitted in the Accelerated Approval Program by the US Food and Drug Administration (FDA) for use in combination with doxorubicin for the treatment of adult patients with STSs. In November 2016, the European Medicines Agency (EMA) granted conditional approval for olaratumab in the same indication under its Accelerated Assessment Program. A double-blind, placebo-controlled, randomized Phase III study (ANNOUNCE trial, NCT02451943) is being performed in order to confirm the survival advantage of olaratumab and to provide definitive drug confirmation by regulators. The study is ongoing, but enrollment is closed. The purpose of this review was to evaluate the rationale of olaratumab in the treatment of advanced STSs and its emerging role in clinical practice.

Abstract
Synovial sarcoma (SS) is a rare sarcoma driven by a translocation between SS18 and SSX 1, 2, or 4. With approximately 800 to 1,000 cases a year in the United States, it most commonly affects young adults between the ages of 15 and 30 years. The resultant tumors are either monophasic (pure sarcomas), biphasic (a combination or epithelioid and sarcomatous components), or poorly differentiated. The hybrid transcription factor SS18:SSX alters SWItch/Sucrose Non-Fermentable (SWI/SNF) chromatin remodeling and global methylation patterns that may allow for future therapeutic opportunities. In this review, we focus on the pharmacologic management of SS, both in the curative setting, where the standard approach is wide surgical excision combined with radiotherapy and/or (neo)adjuvant chemotherapy as appropriate, and in the palliative setting. In advanced disease, chemotherapy with anthracyclines and/or ifosfamide, trabectedin, or pazopanib has been demonstrated to be more active compared with other soft tissue sarcomas. In addition, a better understanding of the molecular and immunologic characteristics of SS has allowed for the identification of new potential targets and the development of novel biology-driven therapies that are all at different stages of testing. There include targeted agents, immunotherapy, and metabolic therapies. Because the impact of these strategies for improving SS outcome is still limited, current and future research is strongly needed to better understand the tumor biology, to identify predictive biomarkers, and to improve the outcomes for patients with SS.

Abstract
In this review, we highlight the complexities of the natural history, biology, and clinical management of three intermediate connective tissue tumors: desmoid tumor (DT) or aggressive fibromatosis, tenosynovial giant cell tumor (TGCT) or diffuse-type pigmented villonodular synovitis (dtPVNS), and giant cell tumor of bone (GCTB). Intermediate histologies include tumors of both soft tissue and bone origin and are locally aggressive and rarely metastatic. Some common aspects to these tumors are that they can be locally infiltrative and/or impinge on critical organs, which leads to disfigurement, pain, loss of function and mobility, neurovascular compromise, and occasionally life-threatening consequences, such as mesenteric, bowel, ureteral, and/or bladder obstruction. DT, PVNS, and GCTB have few and recurrent molecular aberrations but, paradoxically, can have variable natural histories. A multidisciplinary approach is recommended for optimal management. In DT and PVNS, a course of observation may be appropriate, and any intervention should be guided by symptoms and/or disease progression. A surgical approach should take into consideration the infiltrative nature, difficulty in obtaining wide margins, high recurrence rates, acute and chronic surgical morbidities, and impact on quality of life. There are similar concerns with radiation, which especially relate to optimal field and transformation to high-grade radiation-associated sarcomas. Systemic therapies must be considered carefully in light of acute and chronic toxicities. Although standard and novel therapies are promising, many unanswered questions, such as duration of therapy and optimal end points to evaluate efficacy of drugs in clinical practice and trials, exist. Predictive biomarkers and novel clinical trial end points, such as volumetric measurement, magnetic resonance imaging T2 weighted mapping, nuclear imaging, and patient-reported outcomes, are in development and will require validation in prospective trials.

Abstract
Together with surgery and radiotherapy, systemic treatment with cytotoxic chemotherapy and molecular targeted agents is one of the main therapeutic pillars in the treatment of soft-tissue sarcomas and is the mainstay of treatment in patients with advanced or metastatic disease. Unlike other more common malignancies such as breast and colorectal cancer, the role of chemotherapy when used in the adjuvant setting in soft-tissue sarcomas is less well defined. Results from prior studies have been conflicting, in part due to the heterogeneity and rarity of the disease, and large-scale meta-analysis has been performed to address this issue. Neoadjuvant chemotherapy, defined as the use of chemotherapy before definitive treatment with surgery or radiotherapy, has distinct theoretical and practical advantages, which can potentially be beneficial to the patient. However, the currently available evidence to support its use is even more scarce. In this review article, we describe the current established data behind the use of adjuvant chemotherapy in selected patients with localised soft-tissue sarcomas and, through extrapolation of available data, discuss the potential role of it when used in the upfront setting.

Abstract
Soft tissue sarcomas (STS) are a heterogeneous group of rare mesenchymal tumors that account for approximately 1% of all adult malignancies. They can arise throughout the body due to their mesenchymal origin, although 60% of all STS occur in the extremities. Locally advanced STS can lead to significant functional morbidity and tend to local recurrences despite surgical resection. About 30% of all STS patients develop distant metastases with a median overall survival of less than 15 months. The treatment of choice in patients with localized disease is still surgical resection with negative margins. However, there has been a paradigm shift in the last few decades. Large retrospective analyses could not establish a strong association between radical resections and improved local control or survival. Previous radical concepts in STS surgery have been gradually replaced by more moderate approaches with function- and limb-sparing resections combined with radiotherapy. Here, the margin status appears to be of prognostic significance. However, several large retrospective analyses have presented inconsistent results, questioning the independent prognostic impact of surgical margins. This article reviews the literature critically, focusing on the changing role of surgical margins in STS surgery.

Abstract
Gastric liposarcoma is an extremely rare tumour that usually affects the extremities and retroperitoneum. Preoperative diagnosis is difficult, and operative procedures are not well standardised. A 61-year-old woman presented with melaena, epigastric discomfort and palpitations. Upper endoscopy revealed a submucosal tumour at the posterior gastric fundus with an actively bleeding ulcer on the top. Our preoperative diagnosis was lipoma, and we performed laparoscopic intragastric surgery. However, the histopathological diagnosis was liposarcoma. Laparoscopic total gastrectomy was performed to achieve a wide surgical margin. Several recent series have shown that a positive microscopic margin is associated with a higher rate of local recurrence than a negative margin. We have added a staged operation to obtain a wide margin in cases involving a positive surgical margin. Preoperative diagnosis of liposarcoma is still challenging. Gastric lipoma-like tumours should be resected with a wide margin because of their possibility of malignancy.

Abstract
The duration of adjuvant imatinib for high-risk patients with gastrointestinal stromal tumors (GISTs) is still controversial. Therefore, we retrospectively analyzed the data of high-risk patients with GISTs to investigate the appropriate duration. All 185 patients were divided into 4 groups: <1 year (Group A), 1–2 years (Group B), 2–3 years (Group C) and >3 years (Group D). The mean recurrence-free survival (RFS) in Groups A, B, and C were 44.3, 62.1, and 86.8 months, respectively (P < 0.001); the mean overall survival (OS) in Groups A, B and C was 75.2, 88.1, and 94.7 months, respectively (P = 0.009). The 5-year RFS in Groups A, B, C, and D was 15%, 26%, 83%, and 100%, respectively (P < 0.001); and the 5-year OS was 64%, 88%, 88%, and 100%, respectively (P < 0.001). The greatest impact on unfavorable outcomes was the tumor mitotic rate (HR, 2.01, 95% CI, 1.38–2.94; P < 0.001). Duration of adjuvant imatinib was the only favorable factor (HR, −0.95, 95% CI, 0.93–0.97; P < 0.001). For high-risk patients with high tumor size or mitotic rate, or non-gastric GISTs, we recommend that more than 3 years of adjuvant imatinib is feasible.

Abstract
Retroperitoneal sarcomas (RPS) frequently involve major vessels, which either originate from them or secondarily encase or invade them. In this field, major vascular resections result in increased morbidity. However, survival does not seem to be affected by the need for vascular resection or by this higher morbidity. This paper aims to provide descriptions of the surgical strategy and outcomes for retroperitoneal sarcomas involving major vessels.

Abstract
Introduction Recurrence of gastrointestinal stromal tumors (GISTs) after surgical resection and imatinib mesylate (IM) adjuvant therapy poses a significant treatment challenge. We present the case of a patient who underwent surgical resection after recurrence and review the current literature regarding treatment. Case Presentation A 58-year-old man with a large intra-abdominal jejunal GIST was treated with complete surgical resection followed by IM. The patient experienced disease recurrence 3.5 years later and underwent IM dose escalation and reresection. Conclusion Current strategies to treat recurrent GIST include dose escalation, modifying adjuvant tyrosine kinase inhibitor therapy, and surgery. High-level evidence will be required to better define the combinatory roles of tyrosine kinase inhibitor therapy, guided by molecular profiling, and surgery in the management of recurrent GIST.

Abstract
Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumor of digestive tract. In the past, tissue biopsy was the main method for the diagnosis of GISTs. Although, circulating tumor DNA (ctDNA) detection by next-generation sequencing (NGS) may be a feasible and replaceable method for diagnosis of GISTs. We retrospectively analyzed the data for ctDNA and tissue DNA detection from 32 advanced GIST patients. We found that NGS obviously increased the positive rate of ctDNA detection. ctDNA detection identified rare mutations that were not detected in tissue DNA detection. Tumor size and Ki-67 were significant influencing factors of the positive rate of ctDNA detection and concordance between ctDNA and tissue DNA detection. In all patients, the concordance rate between ctDNA and tissue DNA detection was 71.9%, with moderate concordance, but the concordance was strong for patients with tumor size > 10 cm or Ki-67 > 5%. Tumor size, mitotic figure, Ki-67, and ctDNA mutation type were the significant influencing factors of prognosis, but only tumor size and ctDNA mutation type, were the independent prognostic factors for advanced GIST patients. We confirmed that ctDNA detection by NGS is a feasible and promising method for the diagnosis and prognosis of advanced GIST patients. Mol Cancer Ther; 17(1); 290-6. ©2017 AACR.

Abstract
OBJECTIVE The outcome for patients with unresectable hepatic sarcoma is poor with a median survival period of 12-16 months. The purpose of this study was to evaluate liver-directed transcatheter therapies for the treatment of hepatic sarcomas. MATERIALS AND METHODS In a retrospective study, the cases of patients with primary and metastatic hepatic sarcoma treated by transcatheter embolization, chemoembolization, and 90Y radioembolization between 2004 and 2015 were identified. Response Evaluation Criteria in Solid Tumors version 1.1 response was assessed for the target tumor. Survival was assessed by means of Kaplan-Meier analysis. RESULTS Twenty-eight patients (17 [61%] men, 11 [39%] women; median age, 47 years) were included. Eighteen patients were treated electively. Two of the electively treated patients underwent embolization; eight, chemoembolization; six, radioembolization; and two, a combination of transcatheter treatments. Treatment was well tolerated; only one patient had grade 3 hepatic toxicity. The objective response rate of the index tumor was 61%, and the median overall survival period was 26.7 months. Ten patients underwent emergency embolization to control acute hemorrhage from tumor rupture. The median overall survival periods were 611 days for the patients with ruptured gastrointestinal stromal tumors (GIST) (n = 3) and 19 days for the patients with ruptured angiosarcoma (n = 7). CONCLUSION Liver-directed transcatheter therapies are safe and may have a role in the elective management of unresectable primary and metastatic liver sarcomas. Emergency embolization for ruptured GIST may be effective for stabilizing the patient's condition and allowing more definitive therapy in the future. However, emergency embolization has limited efficacy in treating patients with ruptured angiosarcoma, likely because of substantial venous bleeding at rupture and the aggressive behavior of this lesion.

Abstract
BACKGROUND Sarcomas are rare but aggressive diseases. Specialized multidisciplinary management is not implemented for all patients in most countries. We investigated the impact of a multidisciplinary tumor board (MDTB) presentation before treatment in a nationwide study over 5 years. PATIENTS AND METHODS NETSARC (netsarc.org) is a network of 26 reference sarcoma centers with specialized MDTB, funded by the French National Cancer Institute to improve the outcome of sarcoma patients. Since 2010, presentation to an MDTB and second pathological review are mandatory for sarcoma patients in France. Patients' characteristics and follow-up are collected in a database regularly monitored and updated. The management and survival of patients presented to these MDTB before versus after initial treatment were analyzed. RESULTS Out of the 12 528 patients aged ≥15 years, with a first diagnosis of soft tissue and visceral sarcoma obtained between 1 January 2010 and 31 December 2014, 5281 (42.2%) and 7247 (57.8%) were presented to the MDTB before and after the initiation of treatment, respectively. The former group had generally worse prognostic characteristics. Presentation to a MDTB before treatment was associated with a better compliance to clinical practice guidelines, for example, biopsy before surgery, imaging, quality of initial surgery, and less reoperations (all P < 0.001). Local relapse-free survival and relapse-free survival were significantly better in patients presented to a MDTB before initiation of treatment, both in univariate and multivariate analysis. CONCLUSION The compliance to clinical practice guidelines and relapse-free survival of sarcoma patients are significantly better when the initial treatment is guided by a pre-therapeutic specialized MDTB.

Abstract
PURPOSE To evaluate the feasibility and usefulness of computed tomography (CT)-guided iodine125 (125I) brachytherapy for patients with metastatic soft tissue sarcoma (STS) after first-line chemotherapy failure. METHODS We recruited 93 patients with metastatic STS who had received first-line chemotherapy 4-6 times but developed progressive disease, from January 2010 to July 2015; 45 patients who had combined 125I brachytherapy and second-line chemotherapy (Group A), and 48 patients who received second-line CT only (Group B). RESULT In Group A, 49 125I seed implantation procedures were performed in 45 patients with 116 metastatic lesions; the primary success rate was 91.1% (41/45), without life-threatening complications. Local control rates at 3, 6, 12, 24 and 36 months were 71.1%, 62.2%, 46.7%, 28.9% and 11.1% for Group A, and 72.9%, 54.2%, 18.8%, 6.3% and 0% for Group B. Mean progression-free survival differed significantly (Group A: 7.1±1.3 months; Group B: 3.6 ±1.1 months; P<0.001; Cox proportional hazards regression analysis), but overall survival did not significantly differ (Group A: 16.9 ±5.1 months; Group B: 12.1 ± 4.8 months). Group A showed better symptom relief and quality of life than Group B. CONCLUSION CT-guided 125I brachytherapy is a feasible and valuable treatment for patients with metastatic STS. KEY POINTS • 125 I brachytherapy is feasible and valuable for treating metastatic soft tissue sarcoma. • 125 I brachytherapy represents a prominent activity in disease control. • 125 I brachytherapy can achieve better symptom relief and quality of life.

Abstract
Soft tissue sarcomas are rare and aggressive tumors arising from connective tissues. Adjuvant radiotherapy is a commonly used treatment approach for the majority of sarcomas. We attempted to identify a gene signature that can predict radiosensitive patients who are most likely to have a better treatment response from radiotherapy, compared with disease progression. Using the publicly available data of soft tissue sarcoma from The Cancer Genome Atlas, we developed a cross-validation procedure to identify a predictive gene signature for radiosensitivity. The results showed that the predicted radiosensitive patients who received radiotherapy had significantly improved treatment response. We further provide supportive evidence to validate our sensitivity prediction. Results showed that the predicted radiosensitive patients who received radiotherapy had significantly improved survival than patients who did not. ROC analysis showed that the developed gene signature had a powerful prediction on treatment response. We further found that predicted radiosensitive patients who received radiotherapy had a significantly reduced rate of new tumor events. Finally, we validated our gene signature using a hierarchical cluster analysis, and found that the predicted sensitivities were well-matched with results from the cluster analysis. These results are consistent with our expectation, suggesting that the identified gene signature and radiosensitivity prediction are effective. The genes involved in the signature may provide a molecular basis for prognostic studies and radiotherapy target discovery.

Abstract
Constitutive activating mutations in KIT and platelet-derived growth factor receptor α ( PDGFRα) are heavily involved in the pathobiology of gastrointestinal stromal tumors (GISTs). This disease has served as an effective "proof-of-concept" model for targeting gain-of-function kinase mutations in cancer. This review discusses the current standard of care in terms of pharmacotherapy in the management of localized and metastatic GISTs.

Abstract
Background This study aimed to quantify the benefit of adjuvant radiotherapy (AXRT) for local control, distant metastasis, and long-term survival outcomes in patients with localized soft tissue sarcoma (STS). Methods This single-center retrospective observational study enrolled 433 STS patients who underwent surgery with curative intent. An inverse probability of treatment-weighted (IPTW) analysis was implemented to account rigorously for imbalances in prognostic variables between the adjuvant treatment groups. Results During a median follow-up period of 5.5 years, the study observed 38 local recurrences (9%), 73 occurrences of distant metastasis (17%), 63 STS-related deaths (15%), and 57 deaths from other causes (13%). As expected, patients receiving AXRT (n = 258, 60%) were more likely to have high-grade G3 tumors (p < 0.0001) than patients not receiving AXRT. A crude analysis showed that AXRT was not associated with improved recurrence-free survival [hazard ratio (HR) 1.00; 95% confidence interval (CI) 0.72–1.38; p = 0.98]. However, after IPTW, AXRT was associated with a 38% relative reduction in the risk of recurrence or death (HR 0.62; 95% CI 0.39–1.00; p = 0.05). This benefit was driven by a strong reduction in the risk of local recurrence (HR 0.42; 95% CI 0.19–0.91; p = 0.03), whereas the relative risk of distant metastasis (HR 0.69; 95% CI 0.39–1.25; p = 0.22) and overall survival (HR 0.76; 95% CI 0.44–1.30; p = 0.32) were only nonsignificantly in favor of AXRT. An exploratory analysis showed an overall survival benefit of AXRT for patients with high-grade G3 tumors (HR 0.51; 95% CI 0.33–0.78; p = 0.002). However, this finding may have been attributable to residual confounding. Conclusion In this observational cohort, AXRT was associated with a 58% reduction in the relative risk of local recurrence. No consistent association between AXRT and lower risks of distant metastasis or death was observed.

Abstract
BACKGROUND Laparoscopic surgery for gastric gastrointestinal stromal tumors (GISTs) is now widely performed. However, laparoscopic resection of GIST in the esophagogastric junction (EGJ) is technically difficult and rarely reported. Herein, we introduce four fashions of laparoscopic resection for EGJ-GIST. METHODS A retrospective review of 42 consecutive patients with EGJ-GIST who underwent attempted laparoscopic surgery was conducted. EGJ-GIST was defined as GIST with an upper border of less than 5 cm from the esophagogastric line. Four fashions of laparoscopic resection were performed: fashion A, laparoscopic wedge resection using linear stapler; fashion B, laparoscopic complete resection by opening the stomach wall and closing with suture or linear stapler; fashion C, laparoscopic mucosa-preserving resection; and fashion D, laparoscopic proximal gastrectomy with pyloroplasty and gastric plication. Clinicopathologic characteristics, operative course, and short-term and long-term outcomes were analyzed. RESULTS All procedures were completed successfully without operative complications. In 24 of 42 (57.1%) patients, tumors were located in the fundus or greater curvature. Out of those, 70.8% (17/24) received fashion A and 29.2% (7/24) received fashion B. Tumors in 16 of 42 (38.1%) patients were located in the lesser curvature. Of those, 81.3% (13/16) underwent fashion B and 18.7% (3/16) underwent fashion D. One tumor in the anterior stomach wall and one in the posterior wall received fashion C. The mean operative time was 103.8 ± 22.1 min and the mean estimated blood loss was 22.4 ± 13.5 ml. The mean time to flatus was 40.3 ± 12.9 h and the time to fluid intake was 43.2 ± 14.3 h. The mean hospital stay was 4.8 ± 2.1 days. CONCLUSIONS Laparoscopic surgery for EGJ-GIST is safe and feasible. The selection of various laparoscopic resection fashions should be chosen based on tumor location and the surgeon's experience.

Abstract
Soft tissue sarcoma (STS) is a rare tumor with more than 50 histologic subtypes. Although treatment outcomes for patients with STS have improved greatly over the past few decades owing to the adoption of a multidisciplinary approach, patients with advanced disease have a poor prognosis. The development of anticancer drugs has been directed toward improving overall survival (OS). Doxorubicin monotherapy is currently the only standard option for the first-line treatment of STS. However, there is no standard therapy for second-line and later treatment at present. Since 2012, three anticancer drugs—pazopanib, trabectedin, and eribulin—have been approved in Japan for the second-line or later treatment of patients with advanced STS of any histologic subtype. However, the chemosensitivity of STS to each of these drugs varies by histologic subtype and their safety profiles differ; thus, histologic subtype and patient characteristics must be considered when determining optimal treatment. In this article, we review data from clinical studies related to the efficacy of all three drugs, including their effect on OS, and propose optimal treatment strategies for advanced STS by histologic subtype. In addition, with regard to the safety profiles, we highlight the key issues to be considered when selecting patients for treatment with pazopanib, trabectedin, or eribulin and ensuring their appropriate use, based on our combined clinical experience as specialists in the treatment of patients with STS. The proposed treatment strategies as well as treatment precautions based on clinical experience would benefit patients by maximizing the therapeutic effects and enhancing the proper use of these drugs.

Abstract
INTRODUCTION Olaratumab is a humanized IgG1 monoclonal antibody that blocks the platelet-derived growth factor receptor alpha (PDGFRα). Its antagonistic behavior inhibits the receptor's tyrosine kinase activity, thereby, turning off the downstream signaling cascades responsible for soft tissue sarcoma tumorigenesis. In October 2016, olaratumab received Food and Drug Administration (FDA) approval for its use in combination with doxorubicin for treatment of advanced soft tissue sarcoma. Areas covered: This drug profile takes a comprehensive look at the clinical studies leading to FDA approval of olaratumab as well as its safety and efficacy as a front-line treatment option for sarcoma patients. The literature search was primarily conducted using PubMed. Expert commentary: The combination of olaratumab plus doxorubicin has provided a new front-line therapeutic option for soft tissue sarcoma patients. An open-label phase Ib and randomized phase II trial in patients with advanced soft tissue sarcoma demonstrated that the addition of olaratumab to doxorubicin prolonged progression-free survival by 2.5 months and overall survival by 11.8 months when compared to doxorubicin alone. Of importance, this clinically meaningful increase in overall survival did not come at the expense of a significantly greater number of toxicities. A phase III confirmatory trial (ClinicalTrials.gov Identifier NCT02451943) will be completed in 2020.
