A randomized, open-label, phase 2, multicenter trial of gemcitabine with pazopanib or gemcitabine with docetaxel in patients with advanced soft-tissue sarcoma. Cancer 2021; 127:894-904. [PMID: 33231866 DOI: 10.1002/cncr.33216] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Revised: 08/10/2020] [Accepted: 08/20/2020] [Indexed: 11/07/2022]
Abstract
BACKGROUND Therapeutic options for patients with advanced soft-tissue sarcoma (STS) are limited. The goal of the current phase 2 study was to examine the clinical activity and safety of the combination of gemcitabine plus pazopanib, a multityrosine kinase inhibitor with activity in STS. METHODS The current randomized, phase 2 trial enrolled patients with advanced nonadipocytic STS who had received prior anthracycline-based therapy. Patients were assigned 1:1 to receive gemcitabine at a dose of 1000 mg/m2 on days 1 and 8 with pazopanib at a dose of 800 mg daily (G+P) or gemcitabine at a dose of 900 mg/m2 on days 1 and 8 and docetaxel at a dose of 100 mg/m2 on day 8 (G+T) every 3 weeks. Crossover was allowed at the time of disease progression. The study used a noncomparative statistical design based on the precision of 95% confidence intervals for reporting the primary endpoints of median progression-free survival (PFS) and rate of grade ≥3 adverse events (AEs) for these 2 regimens based on the intent-to-treat patient population (AEs were graded using version 4.0 of the National Cancer Institute Common Terminology Criteria for Adverse Events). RESULTS A total of 90 patients were enrolled: 45 patients on each treatment arm. The median PFS was 4.1 months for each arm (P = .3, log-rank test). The best overall response of stable disease or better (complete response + partial response + stable disease) was the same for both treatment arms (64% for both the G+T and G+P arms). The rate of related grade ≥3 AEs was 82% for the G+T arm and 78% for the G+P arm. Related grade ≥3 AEs occurring in ≥10% of patients in the G+T and G+P arms were anemia (36% and 20%, respectively), fatigue (29% and 13%, respectively), thrombocytopenia (53% and 49%, respectively), neutropenia (20% and 49%, respectively), lymphopenia (13% and 11%, respectively), and hypertension (2% and 20%, respectively). CONCLUSIONS The data from the current study have demonstrated the safety and efficacy of G+P as an alternative to G+T for patients with nonadipocytic STS.

Kondo T. Current status and future outlook for patient-derived cancer models from a rare cancer research perspective. Cancer Sci 2021; 112:953-961. [PMID: 32986888 PMCID: PMC7935796 DOI: 10.1111/cas.14669] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2020] [Revised: 09/15/2020] [Accepted: 09/17/2020] [Indexed: 12/19/2022] Open
Abstract
Rare cancers are a group of approximately 200 malignancies with extremely low incidences and with a wide variety of genotypes and phenotypes. Collectively, they are more common than any single malignancy. However, given the small numbers of individuals diagnosed with rare cancers, it is difficult to design clinical trials with sufficient patient numbers. Therefore, few effective anticancer drugs have been developed, and evidence‐based medicine is not always feasible for rare cancers. Consequently, their clinical outcomes are generally poorer. Cancer research requires adequate models that faithfully recapitulate molecular features and reproduce treatment responses of the original tumors. Such models allow us to focus on more efficacious drugs in the clinical studies. For rare cancers, patient‐derived cancer models are particularly important because the enrollment of sufficient patients is rarely attainable within a reasonable period of time. However, extremely few models are available for rare cancers. For example, cell lines and xenografts are available for only a limited number of histological subtypes of sarcomas; therefore, most sarcoma research is performed without such models, and a lack of adequate cancer models causes a lag in therapeutic development. The establishment of novel rare cancer models will dramatically facilitate rare cancer research and treatment development in the near future. This review focuses on the status of patient‐derived rare cancer models and discusses their pivotal problems and possibilities, using sarcomas as a representative rare cancer type. Multi‐institutional collaboration will help address the scarcity of patient‐derived rare cancer models.

Abstract
BACKGROUND Prognosis for patients with metastatic soft tissue sarcomas (STS) is dismal, with median overall survival (OS) of 8-12 months. The role of second-line therapy has been inconsistently investigated over the last 20 years. This systematic review and meta-analysis was performed to assess the efficacy of salvage treatment in pretreated adult type STS, gastrointestinal stromal tumor (GIST) excluded. MATERIAL AND METHODS PubMed, Web of Science, SCOPUS, EMBASE, CINAHL, and The Cochrane Library were searched for randomized phase II/phase III trials exploring second- or beyond therapy lines in pretreated metastatic STS. Two independent investigators extracted data; the quality of eligible studies was resolved by consensus. Hazard ratio (HR) of death and progression (OS and progression-free survival [PFS]) and odds ratio (OR) for response rate (RR) were pooled in a fixed- or random-effects model according to heterogeneity. Study quality was assessed with the Cochrane's risk of bias tool, and publication bias with funnel plots. RESULTS Overall, 10 randomized trials were selected. The pooled HR for death was 0.81 (95% confidence interval [CI] 0.73-0.9). Second-line therapy reduced the risk of progression by 49% (HR = 0.51, 95% CI 0.34-0.76). This translated into an absolute benefit in OS and PFS by 3.3 and 1.6 months, respectively. Finally, RR with new agents or chemotherapy doublets translated from 4.3% to 7.6% (OR = 1.78, 95% CI 1.22-2.50). CONCLUSION Better survival is achieved in patients treated with salvage therapies (chemotherapy, as single or multiple agents or targeted biological agents). A 3-months gain in OS and an almost double RR is observed. Second lines also attained a reduction by 50% the risk of progression. IMPLICATIONS FOR PRACTICE There is some evidence that salvage therapies after first-line failure are able to improve outcome in metastatic soft tissue sarcoma (STS). Trabectedin, gemcitabine-based therapy, and pazopanib are currently approved drugs used after conventional upfront treatment. This meta-analysis reviews the benefit of new agents used in randomized trials in comparison with no active treatments or older agents for recurrent/progressed STS. The results show that modern drugs confer a statistically significant 3-month benefit in terms of overall survival, and an increase in response rate. Despite a limited improvement in outcome, currently approved second-line therapy should be offered to patients with good performance status.

The role of pazopanib on tumour angiogenesis and in the management of cancers: A review. Biomed Pharmacother 2017; 96:768-781.

Abstract
Pazopanib is a relatively new compound to be introduced into the chemotherapy field. It is thought to have decent anti-angiogenic properties, which gives an additional hope for the treatment of certain types of cancers. A systematic review solely discussing about pazopanib and its anti-angiogenic effect is yet to be published to date, despite several relevant clinical trials being conducted over the recent years. In this review, we aim to investigate the mechanism of pazopanib's anti-angiogenic effect and its effectiveness in treating several cancers. We have included, in this study, findings from electronically searchable data from randomized clinical trials, clinical studies, cohort studies and other relevant articles. A total of 352 studies were included in this review. From the studies, the effect of pazopanib in various cancers or models was observed and recorded. Study quality is indefinite, with a few decent quality articles. The most elaborately studied cancers include renal cell carcinoma, solid tumors, advanced solid tumors, soft tissue sarcoma, breast cancer and gynecological cancers. In addition, several less commonly studied cancers are included in the studies as well. Pazopanib had demonstrated its anti-angiogenic effect based on favorable results observed in cancers, which are caused by angiogenesis-related mechanisms, such as renal cell carcinoma, solid tumors, advanced solid tumors and soft tissue sarcoma. This review was conducted to study, analyze and review the anti-angiogenic properties of pazopanib in various cancers. The results obtained can provide a decent reference when considering treatment options for angiogenesis-related malignancies. Furthermore, the definite observations of the anti-angiogenic effects of pazopanib could provide newer insights leading to the future development of drugs of the same mechanism with increased efficiency and reduced adverse effects.

Abstract
Morphologically, canine soft-tissue sarcomas (STSs) resemble human STSs. In humans, proper classification of STSs is considered essential to improve insight in the biology of these tumors, and to optimize diagnosis and therapy. To date, there is a paucity of data published on the significance of detailed classification of STSs in the dog. We revised a cohort (n = 110) of proliferative lesions obtained from a study in Golden Retrievers that were considered "soft tissue sarcoma, not otherwise specified or of uncertain subtype" in order to optimize the diagnoses of these lesions. The criteria according to the veterinary WHO classification, recent veterinary literature, and the WHO classification for humans were applied. Revision was initially based on morphologic characteristics of hematoxylin and eosin-stained histologic sections of the neoplasms. If considered necessary (n = 76), additional immunohistochemistry was applied to aid characterization. The diagnosis of STS was confirmed in 75 neoplasms (68%). Of this group, diagnosis of a specific subtype of the STSs was possible in 58 neoplasms. Seven neoplasms had morphologic characteristics that were suggestive for sarcoma subtypes only described in the WHO classification for humans. Seventeen neoplasms remained "unclassified STSs." Thirty-one lesions (28%) were diagnosed "neoplasm, not being STS." Four lesions (4%) were considered nonneoplastic. Because incorrect classification of a tumor could lead to inappropriate therapeutic intervention and prognostication, the results of our study clearly illustrate the importance of revision and further diagnosis of "unclassified STSs" in dogs.

Abstract
The diversity in sarcoma phenotype and genotype make treatment of this family of diseases exceptionally challenging. Sixty-three human adult and pediatric sarcoma lines were screened with 100 FDA-approved oncology agents and 345 investigational agents. The investigational agents' library enabled comparison of several compounds targeting the same molecular entity allowing comparison of target specificity and heterogeneity of cell line response. Gene expression was derived from exon array data and microRNA expression was derived from direct digital detection assays. The compounds were screened against each cell line at nine concentrations in triplicate with an exposure time of 96 hours using Alamar blue as the endpoint. Results are presented for inhibitors of the following targets: aurora kinase, IGF-1R, MEK, BET bromodomain, and PARP1. Chemical structures, IC50 heat maps, concentration response curves, gene expression, and miR expression heat maps are presented for selected examples. In addition, two cases of exceptional responders are presented. The drug and compound response, gene expression, and microRNA expression data are publicly available at http://sarcoma.cancer.gov. These data provide a unique resource to the cancer research community.

Abstract
The treatment of advanced uterine leiomyosarcomas (U-LMS) represents a considerable challenge. Radiological diagnosis prior to hysterectomy is difficult, with the diagnosis frequently made postoperatively. Whilst a total abdominal hysterectomy is the cornerstone of management of early disease, the role of routine adjuvant pelvic radiotherapy and adjuvant chemotherapy is less clear, since they may improve local tumor control in high risk patients but are not associated with an overall survival benefit. For recurrent or disseminated U-LMS, cytotoxic chemotherapy remains the mainstay of treatment. There have been few active chemotherapy drugs approved for advanced disease, although newer drugs such as trabectedin with its pleiotropic mechanism of actions represent an important addition to the standard front-line systemic therapy with doxorubicin and ifosfamide. In this review, we outline the therapeutic potential and in particular the emerging evidence-based strategy of therapy with trabectedin in patients with advanced U-LMS.

Abstract
Leiomyosarcomas are malignant mesenchymal tumours that derive from the smooth muscle lineage. They are studied and frequently treated as if they are the same as other soft tissue sarcomas. Recent developments suggest that a different approach may be more appropriate. Their underlying genetic mechanisms remain unclear, and complex. Unbalanced karyotypic defects are the only shared features observed across different leiomyosarcoma subtypes. Unlike other soft tissue sarcomas, leiomyosarcomas are particularly sensitive to the combination of gemcitabine and docetaxel. Furthermore, treatment with trabectedin has shown a good efficacy in leiomyosarcomas, mainly in the form of chronic disease stabilisation.

Abstract
INTRODUCTION Pazopanib (GW786034, Votrient®) is a vascular endothelial growth factor receptor-focused multi-tyrosine kinase inhibitor involved in inhibiting the angiogenesis pathway. The agent was recently registered for use in soft tissue sarcomas, a group of diseases with a major unmet medical need. AREAS COVERED The relevance of angiogenesis in soft tissue sarcomas is discussed. These data were the basis to decide on the development of pazopanib in these diseases. The clinical pharmacology of pazopanib, as far as practically relevant, is summarized. After the first observations of possible activity in soft tissue sarcomas in the Phase I study, a Phase II and subsequent randomized placebo-controlled Phase III study were performed and are being put into perspective in this review. EXPERT OPINION Pazopanib is an active drug for the treatment of chemotherapy-failing nonadipocytic soft tissue sarcomas. It almost triples progression-free survival significantly from 1.6 to 4.6 months in this heavily pretreated population. The safety profile is manageable, exemplified by the high dose intensity that can be achieved over time. Pazopanib can be considered as part of the standard of care for patients with soft tissue sarcomas.

Abstract
There is an urgent need to develop new therapies for soft tissue sarcomas. Traditional cytotoxic therapies, such as doxorubicin and ifosfamide, have been the standard approach to this disease. However, newer paradigms are emerging that are less toxic while targeting dysregulated pathways, tumor hypoxia, and genetic translocations. These newer therapies require different measures of activity as standard response criteria may inaccurately measure their effectiveness. Serious consideration of select endpoints and measures of tumor response are crucial to make significant strides in the treatment of sarcomas. Current studies on soft tissue sarcomas are slowly abandoning response rates while employing progression-free survival and time to progression as improved endpoints. With time and data, our understanding of the relative activity of these agents will grow and lead to improved benefits for our patients.

Abstract
Soft tissue sarcomas (STS) represent a diverse group of histologic subtypes with targetable molecular alterations, often treated as a single disease. Sunitinib malate is a multitargeted receptor tyrosine kinase inhibitor active in other solid tumors carrying similar alterations (i.e., imatinib mesylate-refractory gastrointestinal stromal tumors). This single-institution phase II study investigated the safety and efficacy of sunitinib malate in three common STS subtypes. Patients with documented unresectable or metastatic STS (liposarcoma, leiomyosarcoma and malignant fibrous histiocytoma [MFH]), measurable disease, and 3 or less prior lines of therapy were eligible. Treatment consisted of sunitinib malate, 50 mg daily, for 4 weeks every 6 weeks. Forty-eight patients were enrolled, and 35% were heavily pretreated (≥ 2 prior lines of chemotherapy). The safety profile resembled previously known sunitinib malate toxicities. Median progression-free and overall survivals for liposarcoma, leiomyosarcoma, and MFH were 3.9 and 18.6, 4.2 and 10.1 and 2.5 and 13.6 months, respectively. The 3-month progression-free rates in the untreated and pretreated (chemotherapy) patients with liposarcoma, leiomyosarcoma and MFH were 75% and 69.2%, 60%, and 62.5% and 25% and 44.4%, respectively. With the caveats that a minority of patients with potentially indolent or low-grade disease could have been included and the small numbers, a 3-month progression-free rate of >40% suggests activity for sunitinib malate at least in liposarcomas and leiomyosarcomas. Thus, we believe that further investigation in these susceptible STS subtypes is warranted.

Abstract
Background: Despite therapeutic advances, the prognosis of patients with metastatic soft tissue sarcoma (STS) remains extremely poor. The results of a recent clinical phase II study, evaluating the protective effects of the semisynthetic flavonoid 7-mono-O-(β-hydroxyethyl)-rutoside (monoHER) on doxorubicin-induced cardiotoxicity, suggest that monoHER enhances the antitumour activity of doxorubicin in STSs. Methods: To molecularly explain this unexpected finding, we investigated the effect of monoHER on the cytotoxicity of doxorubicin, and the potential involvement of glutathione (GSH) depletion and nuclear factor-κB (NF-κB) inactivation in the chemosensitising effect of monoHER. Results: MonoHER potentiated the antitumour activity of doxorubicin in the human liposarcoma cell line WLS-160. Moreover, the combination of monoHER with doxorubicin induced more apoptosis in WLS-160 cells compared with doxorubicin alone. MonoHER did not reduce intracellular GSH levels. On the other hand, monoHER pretreatment significantly reduced doxorubicin-induced NF-κB activation. Conclusion: These results suggest that reduction of doxorubicin-induced NF-κB activation by monoHER, which sensitises cancer cells to apoptosis, is involved in the chemosensitising effect of monoHER in human liposarcoma cells.

Abstract
Bone and soft tissue sarcomas are an infrequent and heterogeneous group of mesenchymal tumors including more than a hundred different entities attending to histologic patterns. Research into the molecular aspects of sarcomas has increased greatly in the last few years. This enormous amount of knowledge has allowed, for instance, to refine the classification of sarcomas, improve the diagnosis, and increase the number of therapeutical targets available, most of them under preclinical evaluation. However, other important key issues, such as sarcomagenesis and the cell of origin of sarcomas, remain unresolved. From a molecular point of view, these neoplasias are grouped into 2 main types: (a) sarcomas showing relatively simple karyotypes and translocations, which originate gene fusions (eg, EWS-FLI1 in Ewing sarcoma) or point mutations (eg, c-kit in the gastrointestinal tumors) and (b) sarcomas showing unspecific gene alterations, very complex karyotypes, and no translocations. The discovery of the early mechanisms involved in the genesis of sarcomas, the more relevant signaling pathways, and the development of genetically engineered mouse models could also provide a new individualized therapeutic strategy against these tumors. This review describes the clinical application of some of the molecular alterations found in sarcomas, some advances in the field of sarcomagenesis, and the development of animal models.

Abstract
Uterine leiomyosarcomas (LMSs) are rare tumors, comprising 1.3% of all uterine cancers. Primary therapy for localized disease entails complete surgical resection. The majority of patients recur within 2 years of primary therapy as these tumors tend to undergo early hematogenous spread. A randomized, controlled trial showed no improvement in the overall or disease-free survival with adjuvant radiotherapy, compared with observation, following resection of early-stage uterine LMS. A Phase II study of adjuvant chemotherapy following complete surgical resection of uterine LMS reported promising results. However, in the absence of Phase III randomized data demonstrating improved outcomes, the role of post-resection chemotherapy for early-stage disease remains experimental. For metastatic or unresectable LMS, systemic chemotherapy forms the mainstay of treatment. First-line treatment options include gemcitabine-docetaxel or doxorubicin with or without ifosfamide. Novel targeted therapies are under investigation in an attempt to devise more effective treatment strategies.

Abstract
We evaluated the feasibility and toxicity of bevacizumab in combination with sequential high-dose (HD) ifosfamide, carboplatin and etoposide refractory to standard chemotherapy in patients with sarcoma and germ cell cancer (GCC). Sixteen patients (13 sarcomas, 3 GCC) received SD-ICE followed by 4 cycles of HD-ICE, qd22 with stem cell support in combination with bevacizumab. All 16 patients were evaluable for toxicity and efficacy, and received 51 cycles (median 3.3). There was no increase in toxicity except of a relatively high incidence of ifosfamide encephalopathy in 17 cycles when compared with previous HD-ICE protocols. One almost complete response in the patient with GCC, previously progressive with three preceding protocols, was observed. Six patients had a partial response (sarcoma 4/13 patients; GCC 2/3 patients), and five patients stable disease (sarcoma 5/13 patients). The median PFS/OS for sarcoma was 5 months (confidence interval (CI): 3.1-6.9) and 13 months (CI: 3.6-24.4), respectively. To our knowledge, this is the first report of the addition of bevacizumab to HD-ICE. This combination did not show new unexpected toxicities except for a relatively high rate of ifosfamide encephalopathy. The efficacy in these heavily pretreated patients including possible reversal of chemotherapy resistance by the addition of bevacizumab indicates a possible potential of bevacizumab in this combination.
