taxane and Hemangiosarcoma

We propose a literature review of available data on angiosarcoma (AS). AS account for 1% of adult soft tissue sarcoma. Two risk factors are well-establish chronic lymhoedema, previous radiotherapy. Clinical presentations of AS are heterogeneous. Large resection followed, if possible, by adjuvant radiotherapy is the cornerstone of curative intent treatment of localized forms. There are no convincing data supporting the administration of adjuvant chemotherapy. For metastatic or locally advanced AS, doxorubicin and weekly paclitaxel seem to provide the longer progression-free survival. Three phase II or parts of phase II trials have been published in the last 2 years, investigating weekly paclitaxel, sorafenib and imatinib, demonstrating that clinical trials are feasible for such rare diseases. Biological evidences for the key role of angiogentic factors have been accumulated during the last years and support the further investigation of anti-angiogenetic agents alone and almost combination with chemotherapy in such disease.

Angiosarcomas may be primary in the skin, primary in soft tissue or viscera, or secondary to irradiation. All angiosarcomas have a poor prognosis. Taxanes may have efficacy in the treatment of angiosarcoma. Expression of TLE3 has been associated with improved outcome in taxane-treated breast cancers. We studied a series of angiosarcoma with TLE3 immunohistochemistry. Cases of angiosarcoma (98 total cases; 37 cutaneous, 48 soft tissue/visceral and 13 post-irradiation) were retrieved and follow up was obtained. Tumors were classified as 'vasoformative', 'spindled', 'epithelioid' and 'mixed'. TLE3 immunohistochemistry was performed. Statistical analyses were performed. Patients (50 males and 48 females) had a median age of 60.2 years. Tumors had a median size 7.5 cm and were vasoformative (N = 43, 44%), spindled (N = 21, 21%), epithelioid (N = 16, 16%) and mixed (N = 18, 18%). Follow up was available for 89/98 patients (91%): 32 (36%) were dead due to disease, 36 (41%) were dead due to other causes and 21 (24%) remained alive. The median time to death was 2.1 years. TLE3 reactivity was observed in 0/37 (0%) cutaneous angiosarcomas, in 28/48 (58%) cases from soft tissue/viscera and in 4/13 (31%) post-irradiation angiosarcomas. (p = <0.0001). Improved 5-year survival was seen in vasoformative angiosarcomas (p = 0.03). TLE3 expression was not associated with taxane response. However, only a subset of patients was treated with taxane. Our study confirms the poor prognosis of angiosarcoma. Vasoformative angiosarcoma may have a more favorable prognosis. A lack of TLE3 expression in cutaneous angiosarcoma may reflect differing pathogenesis.

Cutaneous angiosarcoma (CAS) is a rare and highly aggressive type of vascular tumor. Although chemoradiotherapy with taxanes is recognized as a first-line therapy for CAS, second-line therapy for CAS remains controversial. From the above findings, the efficacy and safety profiles of taxane-switch (change paclitaxel to docetaxel or vise), eribulin methylate, and pazopanib regimens in second-line chemotherapy were evaluated retrospectively in 50 Japanese taxane-resistant CAS patients. Although there was no significant difference in progression-free survival (P = 0.3528) among the regimens, the incidence of all adverse events (AEs) (P = 0.0386), as well as severe G3 or more AEs (P = 0.0477) was significantly higher in the eribulin methylate group and pazopanib group than in the taxane-switch group. The present data suggest that switching to another taxane should be considered for the treatment of taxane-resistant CAS in second-line therapy based on the safety profiles.

Cutaneous angiosarcoma (CAS) is a rare soft-tissue sarcoma of vascular endothelial origin. Paclitaxel (PTX) and docetaxel (DTX) are used as systemic chemotherapy; however, chemoresistance often occurs in CAS. Switching one taxane to the other (i.e., PTX to DTX, or vice versa) is an option when the first taxane is no longer effective in malignant cancers such as ovarian or breast cancer. However, the efficacy of the same strategy in CAS has not been reported. Herein, we report the clinical response of switching one taxane-based chemotherapy to the other in CAS patients with resistance to the first taxane. Twelve CAS patients were included for analyses. In all patients, the median overall survival from the start of the first taxane treatment was 29.0 months (range, 6.47-58.5). During the first taxane, the median PFS for all patients was 5.96 months (1.81-47.1). Similarly, the median (range) PFS for all patients during the second taxane was 5.87 months (1.60-18.2). Furthermore, the median OS was 22.7 months (PTX to DTX) and 39.5 months (DTX to PTX) (p = 0.307). The median PFS during the first taxane was 5.14 (PTX to DTX) and 12.5 months (DTX to PTX), respectively (p = 0.380). The median PFS during the second taxane was 3.5 (PTX to DTX) and 7.1 months (DTX to PTX), respectively (p = 0.906). The objective response rate, defined as the sum of complete response (CR) and partial response (PR) rates, was 16.7%. The disease control rate, defined as the sum of CR, PR, and stable disease rates, was 50%. The frequency of adverse events during the second taxane was the same between the two groups (p > 0.999). Our report suggests that CAS patients could benefit from the second taxane treatment if the tumor is resistant to the first taxane.

Taxanes are the current first-line treatment for advanced cutaneous angiosarcoma (CAS) for patients who are considered difficult to treat with doxorubicin owing to advanced age or comorbidity. However, no effective second-line therapy for such patients has been established.. We designed a single-arm prospective observational study of eribulin mesylate (ERB) administered at a dose of 1·4 mg m. We enrolled a total of 25 patients. The median OS and PFS were 8·6 months and 3·0 months, respectively. The best overall RR was 20% (five of 25). In total, 16 grade 3/4 severe adverse events (SAEs) occurred; however, all patients recovered. Patients who achieved partial response or stable disease as best response had longer OS than those with progressive disease (median OS not reached and 3·3 months, respectively; P < 0·001). Patients who did not experience SAEs showed longer OS than those who did (median OS 18·8 months and 7·5 months, respectively; P < 0·05). Patients with distant metastasis had shorter median OS than those with locoregional disease, but without statistically significant difference.. ERB showed a promising RR and is a potential candidate for second-line treatment for patients with CAS, after treatment with taxanes. However, owing to the occurrence of SAEs in over half of the participants, caution should be exercised regarding ERB use in elderly patients. What is already known about this topic? Taxanes are the current first-line treatment for patients with advanced cutaneous angiosarcoma (CAS) who are considered difficult to treat with doxorubicin owing to advanced age or comorbidity. No effective therapy for taxane-resistant CAS has been established thus far. Eribulin suppresses microtubule polymerization and elicits an antitumour effect similar to that of taxanes. What does this study add? In our single-arm prospective observational study to evaluate the efficacy of eribulin for treating patients with advanced CAS who previously received taxanes, the median overall survival and progression-free survival were 8·6 and 3·0 months, respectively. Response rates at weeks 7, 13 and 25 were 20%, 17% and 14%, respectively. Although 16 grade 3/4 severe adverse events occurred, all patients recovered. Eribulin showed a promising response rate and is a potential candidate for second-line treatment in CAS after taxane treatment. Linked Comment: Smrke and Benson. Br J Dermatol 2020; 183:797-798.

Primary angiosarcoma of the breast is a rare entity with incidence of less than 0.05% of all malignant breast neoplasms. It occurs in young females without any associated risk factors. The tumor behaves aggressively and has a poor prognosis compared to invasive ductal carcinoma.. It was a retrospective observational study done at a tertiary cancer center from January 2012 to December 2016. The medical records of patients diagnosed with primary breast angiosarcoma were reviewed for the study. Clinicopathological profile, treatment, and the outcomes were analyzed.. Four patients were diagnosed with primary breast angiosarcoma out of 2560 breast cancer patients seen over a period of 5 years. Two had metastatic disease at presentation. Among four patients, two underwent surgery of the primary tumor, whereas, all received chemotherapy either as adjuvant or palliative setting. One patient received adjuvant radiation therapy. Three patients received 2nd line and one received 3rd line chemotherapy on disease progression. After a median follow-up of 18 months one patient was surviving on 3rd line chemotherapy with trabectedin. Other three succumbed to disease after progression.. Due to a small number of this malignancy randomized studies are difficult to perform and optimum treatment strategy still need to be defined.

Angiosarcoma is a rare malignant neoplasm derived from endothelial cells, and because advanced angiosarcoma is resistant to standard chemotherapy its prognosis is poor. Therefore, new therapies are urgently needed. Heat shock protein (HSP)90 has been identified as a molecular chaperone that regulates various cancer-related proteins. Numerous clinical trials are currently testing the effectiveness of HSP90 inhibitors in various types of malignancies.. To investigate the role of HSP90 in the pathogenesis of angiosarcoma and whether the inhibition of HSP90 may have antitumour activity.. The expression of HSP90 protein in angiosarcoma was examined using immunohistochemistry and immunoblotting. The effects of HSP90 inhibition were proven using proliferation, migration and invasion assay in angiosarcoma cells. The mechanism of antitumour effect by HSP90 inhibition was investigated by the transfection of small interfering RNA (siRNA).. The levels of HSP90 protein expression in cultured angiosarcoma cell lines were markedly increased compared with those in normal tissue cell lines. Immunohistochemical analyses revealed that the expression of HSP90 protein was strongly detected in angiosarcoma tissues compared with that in normal dermal vessels or senile angioma tissues. Ganetespib, an HSP90 inhibitor, with or without taxanes, inhibited the proliferation of angiosarcoma cells via apoptosis in a dose-dependent manner. HSP90 siRNA suppressed the proliferation, migration and invasion of angiosarcoma cells. Knock-down of HSP90 did not suppress vascular endothelial growth factor receptor 2 directly, but selectively suppressed several downstream targets of vascular endothelial growth factor signalling in angiosarcoma cells.. HSP90 could be a novel therapeutic target for angiosarcoma.

Although cutaneous angiosarcoma (cAS) has one of the worst prognoses among malignant skin tumors, few effective drug options for secondary treatment have been discovered to date because of the limited number of cases. Therefore, this study was aimed at determining pazopanib's potential as a new cAS treatment option. We retrospectively evaluated five patients with taxane-resistant unresectable cAS treated with pazopanib at a university hospital. Their characteristics and treatment outcomes were retrieved from their records. Progression-free survival (PFS), overall survival (OS), disease progression, and toxicity were evaluated; furthermore, the response to pazopanib was assessed in relation to the expression of vascular endothelial growth factor receptor 2 (VEGFR-2). The median PFS from the time of pazopanib initiation was 94 days. Two patients showed partial response, two showed stable disease, and one had progressive disease in the case of the best overall response. VEGFR-2 expression was positive in all cases, and patients with high expression had improved median OS compared to that in those with low expression. VEGFR-2 expression was correlated with a longer OS. The most common toxicities were hypertension and anorexia followed by myelosuppression. This is the largest case series reported wherein pazopanib was used for taxane-resistant cAS. Although the cytoreductive effect and survival benefits were not significant in this small sample, we consider pazopanib a valid treatment option for preserving patients' quality of life. Our results suggest pazopanib treatment slows the progression of disease and stabilizes it in patients with taxane-resistant cAS.

The prognosis of cutaneous angiosarcoma (CAS), especially for patients with tumours > 5 cm has been reported to be dismal, even after conventional surgery and radiotherapy (S + RT).. To demonstrate the efficacy of chemoradiotherapy with taxane (T + RT) and maintenance chemotherapy.. We retrospectively reviewed 16 patients with CAS treated with T + RT and 12 patients treated with S + RT. None had distant metastasis. Tumour sites included the scalp (n = 25) and limbs (n = 3). The chemotherapy regimens used in T + RT were monthly docetaxel (n = 10), biweekly docetaxel (n = 1), weekly docetaxel (n = 5) and weekly paclitaxel (n = 1). The median radiation dose was 70 Gy. Nine patients receiving T + RT continued chemotherapy as maintenance therapy (monthly docetaxel in nine patients and monthly paclitaxel in two patients) and four patients receiving S + RT received adjuvant chemotherapy (weekly docetaxel).. The response ratio of T + RT was 94% (14 complete remission and one partial remission). The 5-year overall survival (OS) rate of patients receiving T + RT was statistically higher than those receiving conventional S + RT (56% and 8%, respectively; P < 0·01). Moreover, patients who received T + RT with maintenance chemotherapy showed a significant improvement in OS than those receiving T + RT alone (P < 0·01). There was a strong trend for relapse-free survival, but it was not significant (P = 0·07). These data indicate that maintenance chemotherapy is crucial for long-term survival after T + RT.. From these results, we suggest that T + RT followed by maintenance chemotherapy is a plausible method for managing CAS, especially large tumours that are difficult to manage with S + RT alone.

To show the efficacy of taxane-based chemotherapy for the treatment of cutaneous angiosarcoma.. A case-control study comparing patients who received taxanes without wide local excision (group A, n = 5) and patients who received conventional surgery-based therapy (group B, n = 8) in one university hospital in eastern Japan. Data were collected from a total of 13 patients with cutaneous angiosarcoma treated from November 1997 through July 2009.. Group A received taxanes: four patients received docetaxel, and one patient received paclitaxel. Radiation was used concomitantly in two patients. Marginal local excision was performed in two patients. Group B received wide local excision followed by radiation (six patients), docetaxel (three patients), and interleukin-2 (two patients). No patients in group A had local recurrence, whereas five out of the eight patients in group B did (p < 0.05, chi-square test). Median overall survival was 31 months in group A and 10 months in group B. Estimated overall survival using the Kaplan-Meier method was significantly longer in group A (p < 0.05, log-rank test).. In our series, taxane-based chemotherapy was superior to conventional surgery-based therapy. Our results indicated that taxane regimens without mutilating surgery offered both local control and prevention of metastasis, which led to prolonged survival.
