Weekly cisplatin with or without imatinib in advanced chordoma: A retrospective case-series analysis from the Italian Rare Cancers Network
2021
Background: To report on a retrospective case-series analysis of weekly cisplatin (wCDDP) as a single agent or combined with imatinib (wCDDP/I) in patients with advanced chordoma treated within the Italian Rare Cancer Network. Methods: Adult patients with a diagnosis of advanced, brachyury-positive chordoma, treated from April 2007 to October 2020 with wCDDP or wCDDP/I were retrospectively identified. Imatinib was withheld at the same time as wCDDP. Response according to Response Evaluation Criteria in Solid Tumors, overall survival (OS), and progression-free survival (PFS) were analyzed. Results: Thirty-three consecutive patients were identified (wCDDP as front-line n = 8 [24.2%]; wCDDP as…
Unravelling the heterogeneity of soft tissue and bone sarcoma patients’ health-related quality of life: a systematic literature review with focus on …
2020
Contains fulltext : 229532.pdf (Publisher’s version ) (Open Access) Patients with sarcoma experience many physical and psychological symptoms, adversely affecting their health-related quality of life (HRQoL). HRQoL assessment is challenging due to the diversity of the disease. This review aims to unravel the heterogeneity of HRQoL of patients with sarcoma with regard to tumour location and to summarise the used measures in research. English-language literature from four databases published between January 2000 and April 2019 was reviewed. Studies that described adult sarcoma HRQoL outcomes were included and classified according to primary sarcoma location. Eighty-seven articles met the incl…
Clinical prognostic factors in advanced epithelioid haemangioendothelioma: a retrospective case series analysis within the Italian Rare Cancers Netwo…
2021
Background This multicentric, retrospective study conducted within the Italian Rare Cancer Network describes clinical features and explores their possible prognostic relevance in patients with advanced epithelioid haemangioendothelioma (EHE) started on surveillance. Patients and methods We collected data on adult patients with molecularly confirmed, advanced EHE consecutively referred at five sarcoma reference centres between January 2010 and June 2018, with no evidence of progressive disease (PD) and started on surveillance. Overall survival (OS) and progression-free survival (PFS) univariable and multivariable Cox analyses were performed. In the latter, due to the low number of cases and …
Primary Orbital Liposarcoma in Li-Fraumeni Cancer Family Syndrome: A Case Report
2005
Aims and background The aim of this study was to describe a case of primary orbital liposarcoma in Li-Fraumeni syndrome. Methods and study design In July 1998 a 20-year-old woman with a histological diagnosis of orbital myxoid liposarcoma underwent surgical treatment in our department. Since the patient's family pedigree met the clinical criteria for the diagnosis of LFS, molecular analysis was performed, which resulted in a molecular profile consistent with Li-Fraumeni syndrome. Results The patient underwent orbital exenteration extended to the upper eyelid; surgical reconstructive steps were performed to permit placement of an orbital prosthesis. Two years after primary surgery the patien…
Spontaneous Resolution of Delayed Suprachoroidal Hemorrhage in the Single Eye Following Needling in Congenital Glaucoma
2017
Suprachoroidal hemorrhage (SCH) is a rare, but potentially vision-threatening event with poor long-term visual prognosis. At present, there is disagreement whether surgical intervention or conservative treatment is superior in the management. We report on a case of spontaneous resolution of severe SCH after needling procedure in the only eye of a young patient with congenital glaucoma.A 43-year-old woman with congenital glaucoma was scheduled for bleb needling in her only eye. Preoperative best-corrected visual acuity was 20/40 and intraocular pressure 20 mm Hg. On the third postoperative day, she developed a massive delayed SCH with appositional (kissing) choroidal bullae and visual acuity…
MDM2 and CDKN1A gene polymorphisms and risk of Kaposi's sarcoma in African and Caucasian patients
2010
A single-nucleotide polymorphism in the MDM2 promoter (SNP309; rs2279744) causes elevated transcription of this major negative regulator of p53 in several cancer types. We investigated MDM2 SNP309 and CDKN1A (p21/Waf1/Cip1) codon 31 (rs1801270) polymorphisms in 86 cases of cutaneous Kaposi's sarcoma (KS) from African and Caucasian patients, and 210 healthy controls. A significant increase of the MDM2 SNP309 T/G genotype was observed among classic KS cases (odds ratio 2.38, 95% confidence interval 1.0-5.5). Frequencies of CDKN1A codon 31 genotypes were not significantly different between cases and controls. The results suggest that the MDM2 SNP309 G allele may act as a susceptibility gene fo…
Molecular analysis of the 9p21 locus and p53 genes in Ewing family tumors.
2001
The EWS-ETS rearrangements, and their respective fusion gene products, are specifically associated with histopathologically Ewing family tumors (EFT). These translocations are implicated in generating malignant transformation of EFT, but the presence of additional genetic alterations must be considered in the pathogenesis of such tumors. We analyzed 26 samples (biopsies and/or nude mice xenotransplants) collected from 19 patients with an EFT to determine whether molecular and cytogenetic alterations of the G(1)/S checkpoint genes are implicated in the pathogenesis of EFT. We found inactivating p53 mutations in three (16%) cases, which correlated with a loss of p21(WAF1/Cip1) expression and …
Primitive Neuroectodermal Tumor (PNET) of the kidney: a case report.
2004
Abstract Background A case of Primitive Neuroectodermal Tumor (PNET) of the kidney in a 27-year-old woman is presented. Few cases are reported in the literature with a variable, nonspecific presentation and an aggressive behaviour. In our case, a radical nephrectomy with lymphadenectomy was performed and there was no residual or recurrent tumour at 24-month follow-up. Methods The surgical specimens were formalin-fixed and paraffin embedded. The sections were stained with routinary H&E. Immunohistochemistry was performed. Results The immunohistochemical evaluation revealed a diffuse CD99 positivity in the cytoplasm of the neoplastic cells. Pankeratin, cytokeratin AE1/AE3, vimentin, desmin, S…
Myeloid sarcoma: clinico-pathologic, phenotypic and cytogenetic analysis of 92 adult patients.
2007
Myeloid sarcoma ( MS) is a rare neoplasm whose knowledge is largely based on case reports and/or technically dated contributions. Ninety-two MSs in adulthood with clinical data available were evaluated both morphologically and immunohistochemically. Seventy-four cases were also studied by fluorescent in situ hybridization on tissue sections and/or conventional karyotyping on bone marrow or peripheral blood. Histologically, 50% of the tumors were of the blastic type, 43.5% either monoblastic or myelomonocytic and 6.5% corresponded to different histotypes. CD68/KP1 was the most commonly expressed marker (100%), followed by myeloperoxidase (83.6%), CD117 (80.4%), CD99 (54.3%), CD68/PG-M1 (51%)…
Identification and expansion of human osteosarcoma-cancer-stem cells by long-term 3-aminobenzamide treatment
2009
A novel cancer stem-like cell line (3AB-OS), expressing a number of pluripotent stem cell markers, was irreversibly selected from human osteosarcoma MG-63 cells by long-term treatment (100 days) with 3-aminobenzamide (3AB). 3AB-OS cells are a heterogeneous and stable cell population composed by three types of fibroblastoid cells, spindle-shaped, polygonal-shaped, and rounded-shaped. With respect to MG-63 cells, 3AB-OS cells are extremely smaller, possess a much greater capacity to form spheres, a stronger self-renewal ability and much higher levels of cell cycle markers which account for G1-S/G2-M phases progression. Differently from MG-63 cells, 3AB-OS cells can be reseeded unlimitedly wit…
