Background. Primary breast angiosarcoma is a rare entity.Case. Initial diagnosis was a benign hemangioma at core biopsy. Wide local excision was performed, with positive margins. Pathology after surgery reported a moderately differentiated angiosarcoma. Tumor was finally treated using mastectomy and radiations. She developed a second angiosarcoma in contralateral breast, with an initial diagnosis on core biopsy of an atypical vascular lesion and was again treated using mastectomy and radiations. She developed bones and lung metastases.Conclusion. Primary breast angiosarcoma is a rare entity often difficult to diagnose on core biopsy, and a benign differential diagnosis is frequent. A highly vascular breast mass should always be considered malignant until proven otherwise. Surgical treatment seems to be the best course of action. There is a lack of data proving efficacy of adjuvant chemotherapy and radiation therapy.

Primary pineal malignant melanoma is a rare entity, with only thirteen cases reported in the world literature to date. We report a case of a 70-year-old man, who consulted with gait disturbance of six months duration, associated in the last month with dizziness, visual abnormalities and diplopia. No other additional melanocytic lesions were found elsewhere. The magnetic resonance showed a 25 mm expansive mass in the pineal gland that was associated with hydrocephaly, ventricular and transependimary oedema. The lesion was partially excised by a supracerebellar infratentorial approach. The histological examination revealed a melanoma. The patient received radiation therapy, but died of disease 16 weeks later. We herein review the literature on this rare tumour and comment on its clinical, radiological and histopathological features and differential diagnosis.

Abstract Background Myxoid liposarcoma (MLS) has the tendency to metastasize extrapulmonary. Although prognostic factors at the initial diagnosis of MLS have been reported, those at diagnosis of metastasis remain unclear. The purpose of this study was to investigate the prognostic factors for disease-specific survival at the initial diagnosis of metastasis. Methods This retrospective observational study was conducted at three cancer centers and two university hospitals in Japan. Of 274 MLS patients pathologically diagnosed between 2001 and 2015, 48 metastatic patients were examined. Results Lung metastases were detected in nine patients (18.8%) and extrapulmonary metastases in 45 (93.8%). Interval from primary diagnosis to the first metastasis was significantly shorter in patients with lung metastases than without ( p = 0.007). Median disease-specific survival after diagnosis of metastases was 52.5 months in all patients. In multivariable analysis, liver metastasis (hazard ratio (HR), 2.71 [95% confidence interval (CI), 1.00–7.09]) and no evidence of disease (NED) achieved by radical treatment (resection with or without radiation therapy, or radiation therapy ≥60 Gy) or semi-radical (radiation therapy ≥40 Gy) treatment were significantly related to survival (HR, 0.36; 95%CI [0.13–0.95]). The number of metastases (odds ratio (OR), 0.44; 95%CI [0.25–0.78]) and abdominal/retroperitoneal metastases (OR, 0.09; 95%CI [0.008–0.95]) were the significant inhibitory factors of achieving NED. Conclusions This is the first study to statistically demonstrate the importance of achieving NED with surgical resection or radiation therapy for longer survival in metastatic MLS patients. As number of metastases was a significant factor for achieving NED, early detection of metastases might be important.

Background: Radio-frequency ablation (RFA) and Stereotactic Body Radiation Therapy (SBRT) are two emerging therapies for lung metastases. Introduction: We performed a literature review to evaluate outcomes and complications of these procedures in patients with lung metastases from soft tissue sarcoma (STS). Method: After selection, seven studies were included for each treatment encompassing a total of 424 patients: 218 in the SBRT group and 206 in the RFA group. Results: The mean age ranged from 47.9 to 64 years in the SBRT group and from 48 to 62.7 years in the RFA group. The most common histologic subtype was, in both groups, leiomyosarcoma. : In the SBRT group, median overall survival ranged from 25.2 to 69 months and median disease-free interval from 8.4 to 45 months. Two out of seven studies reported G3 and one G3 toxicity, respectively. In RFA patients, overall survival ranged from 15 to 50 months. The most frequent complication was pneumothorax. : Local control showed high percentage for both procedures. Conclusion: SBRT is recommended in patients unsuitable to surgery, in synchronous bilateral pulmonary metastases, in case of deep lesions and in patients receiving high-risk systemic therapies. RFA is indicated in case of a long disease-free interval, in oligometastatic disease, when only the lung is involved, in small size lesions far from large vessels. : Further large randomized studies are necessary to establish whether these treatments may also represent a reliable alternative to surgery.

BackgroundOsteosarcoma is the most common primary bone tumor and has a peak incidence in adolescence. The prognosis for recurrent and metastatic disease is poor and over one-third of patients with localized disease at presentation will recur after treatment with metastases. LOFU produces non-lethal, transient mechanical and thermal stress to cause protein misfolding, endoplasmic reticulum stress, and induction of the heat shock response (refs). Trabectedin is directly tumoricidal through inhibiting transcription and DNA repair, modulates the tumor microenvironment by selectively depleting M2 macrophages, and inhibits the transcription factor heat shock factor 1 (HSF1) (refs). We hypothesized that combination therapy would synergistically intensify the unfolded protein response and heat shock response to facilitate antigen presenting cell activation and efficient presentation to cytotoxic T cells. To examine this, experiments are being conducted to investigate the effect of LOFU in combination with trabectedin and/or radiation therapy (RT) in a murine model of osteosarcoma.MethodsPalpable (<5 mm) subcutaneous K7M2 murine osteosarcoma tumors in BALB/c mice were treated with a) LOFU, b) trabectedin (intravenous (IV) or intratumoral (IT)), c) LOFU + trabectedin, and d) radiation. Tumor growth (ANOVA (Kruskal-Wallis) with Dunn’s test for multiple comparisons), pulmonary metastases (Fisher’s exact test) and survival (Kaplan-Meier) were measured and analyzed in GraphPad Prism.ResultsMean tumor volume in the combination therapy group (428 mm3) was less than nontreated controls (887 mm3), LOFU alone (670 mm3), trabectedin alone (1218 mm3, p=0.0386). Radiation therapy resulted in complete ablation of the tumors. None of the combination therapy mice had grossly detectable lung metastases at time of death but metastases were present in the trabectedin only (20%), LOFU only (50%), and control (50%) groups (not statistically significant).ConclusionsCombination therapy with trabectedin and LOFU yielded smaller tumor size and fewer pulmonary metastases compared to individual therapies alone.
