Response dataset from canine extramedullary plasmacytoma treated with lipophobic drugs enhanced by electroporation.

ABSTRACT: Over the past 15 years, lipophobic drugs, such as bleomycin and cisplatin, have been used combined with electroporation, which promotes their uptake through the cell membrane. The present data describe general findings following electrochemotherapy and how plasmacytomas can respond to this technique. We will explain and illustrate specific outcomes during the remission process. The data presented here can be useful for researchers, veterinarians, and pet owners. Furthermore, the data could be useful for other cutaneous or oral tumors in which electrochemotherapy may be indicated. Interpretation of the data and outcomes may be found in the research article entitled "Outcome following curative-intent electrochemotherapy for extramedullary plasmocytoma in dogs - case reports ."

Solitary Extramedullary Plasmacytoma of the Cricoid Cartilage-Case Report.

Project description:Solitary plasmacytoma (SP) is an extremely rare form of hematologic malignancy that can be classified as solitary bone plasmacytoma or solitary extramedullary plasmacytoma. Here, we report a patient who presented with progressive shortness of breath and foreign body sensation in his throat. Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) demonstrated an abnormal FDG-avid soft tissue mass arising from the larynx involving the cricoid cartilage without additional suspicious lesions. Histology revealed an abundance of plasma cells; immunohistochemistry was positive for CD138 expression and lambda chains, and negative for CD20. Comprehensive imaging studies and panendoscopy of the ENT tract confirmed solitary disease involvement. Following additional systemic work-up, a diagnosis of extramedullary plasmacytoma was rendered. The patient underwent definitive radiotherapy using intensity-modulated radiation therapy (total dose of 46?Gy, divided in 23 fractions of 200?cGy). Serial PET/CT showed the stepwise resolution of abnormal FDG uptake and resolution of the cricoid cartilage lesion. With 22?months of follow-up, the patient remains free of disease. We describe the rare case of SP presenting as a FDG-avid hypermetabolic soft tissue mass in the cricoid cartilage, which should be considered in the differential diagnosis of laryngeal tumors. Of note, SP is radiosensitive; favorable outcome can be expected once treated with doses of 40-50?Gy. FDG PET/CT is helpful in diagnosis and response assessment for this disease.

Relapsed multiple myeloma manifesting as extramedullary plasmacytoma of the breast: Imaging findings.

Project description:Extramedullary plasmacytoma of the breast (EPB), a manifestation of multiple myeloma (MM), is very rare. It is important to recognize the imaging findings of EPB because it may be the first manifestation of relapsed MM. An 85-year-old woman presented with a lump in her right breast 4 years after the complete remission of MM. She underwent mammography and ultrasonography, which showed an oval circumscribed mass and an irregular circumscribed heterogeneous solid mass, respectively. Following ultrasound-guided vacuum-assisted breast biopsy, this lesion was confirmed to be EPB. Whole-body computed tomography showed multiple new osteolytic lesions and other multiple extramedullary lesions in addition to EPB in the right breast. The final diagnosis was relapsed MM with multiple extramedullary plasmacytoma.

Multiple primary cutaneous plasmacytoma a decade after a nasal solitary extramedullary plasmacytoma: a puzzling case.

Project description:Primary cutaneous plasmacytoma should be in the differential diagnosis in case of solitary or multiple erythematous-violaceous nodules or papules. The diagnosis relies on clinical, histological, and immunochemical findings, without underlying evidence of multiple myeloma. Treatment should be individualized, and agents such as bortezomib or lenalidomide have shown to be effective.

Extramedullary nasal plasmacytoma: Literature review and a rare case report.

Project description:INTRODUCTION: Extramedullary plasmacytoma is a plasma cell tumor that grows within any of the soft tissues of the organism. Similar to all plasmacytic dyscrasia, the disease is extremely rare. AIM: This study reports a case of an extramedullary plasmacytoma of the nasal cavity and provides a literature review on the topic. CASE REPORT: A 51-year-old woman presented at our tertiary university hospital with a 6-month history of progressive nasal obstruction, predominantly to the right side, and self-limiting epistaxis. Examination revealed a large pale-reddish tumor within the right nasal cavity. Anatomopathological analysis showed features consistent with a plasmacytoma diagnosis, which was subsequently confirmed by immunohistochemical techniques. Further assessment revealed the solitary nature of the condition, consistent with extramedullary plasmacytoma. Radiotherapy was initiated, which led to partial regression of the symptoms. The tumor was surgically removed by using a mid-facial degloving approach. The patient evolved with a naso-oral fistula and underwent 3 corrective surgeries. No evidence of associated systemic disease was found after 5 years of follow-up. CONCLUSIONS: This case report, which describes a rare tumor of the nasal cavity, is expected to improve the recognition and referral of this condition by ear, nose, and throat (ENT) specialists for multidisciplinary management and long-term follow-up.

Primary extramedullary plasmacytoma of the eyelid conjunctiva - A case report and review of the literature.

Project description:Extramedullary plasmacytomas (EMPs) are uncommon plasma cell tumors that develop in soft tissue as isolated tumors without osseous involvement while secondary lesions are associated with systemic multiple myeloma (MM). Primary extramedullary lesions are most commonly found in upper respiratory tract, gastrointestinal tract and lymph nodes. They can be found either in patients with history of MM or preceding the manifestation of a systemic disease. Orbital manifestation of the lesion is rare but conjunctival involvement is very unusual. The reported cases in the English-written literature are only five cases. Herein, we report the sixth case of primary EMP in a middle-aged adult who presented with a lesion confined to the conjunctiva, unremarkable present and past medical history, and confirmed tissue diagnosis. In addition, a review and summary of the previously reported cases in the literature is presented. We aim to attract the attention of ophthalmic surgeons to consider plasmacytoma within the differential diagnosis of a conjunctival lesion.

Strategy for the treatment and follow-up of sinonasal solitary extramedullary plasmacytoma: a case series.

Project description:Extramedullary plasmacytoma is a rare neoplasm characterized by monoclonal proliferation of plasma cells outside bone marrow. It accounts for 4% of all non-epithelial sinonasal tumors. According to the literature, radiotherapy is the standard therapy for extramedullary plasmacytoma. However, the conversion rate of extramedullary plasmacytoma to multiple myeloma is reported to be between 11 and 33% over 10 years. The highest risk of conversion is reported during the first 2 years after diagnosis, but conversion has been noted up to 15 years after diagnosis. Once conversion to multiple myeloma is complete, less than 10% of patients will survive 10 years.We present three cases of sinonasal extramedullary plasmacytoma who underwent radiotherapy: a 61-year-old white man, a 60-year-old white man, and a 37-year-old white woman. We found long-term survival with stable disease in all three cases.The management of solitary extramedullary plasmacytomas of the sinonasal tract is not well established yet. However, the possibility of recurrence and progression to multiple myeloma requires a thorough follow-up protocol. Due to the absence of a standardized protocol for these tumors, we tried to design a tailored long-term follow-up scheme.

Enhanced angiogenic activity of dimethyloxalylglycine-treated canine adipose tissue-derived mesenchymal stem cells.

Project description:The paracrine function of mesenchymal stem cells (MSCs) during transplantation has been recently studied due to its poor differentiation ratio. Dimethyloxalylglycine (DMOG) has been used to promote angiogenesis in experimental animal models, however, comparable approaches for canine MSCs are not sufficient. In the present study, we assessed whether DMOG improves angiogenesis in canine adipose tissue-derived mesenchymal stem cells (cAT-MSCs). cAT-MSCs were treated with DMOG and their effect on angiogenesis was investigated by cell proliferation assay, western blotting, and tube formation assay. Dimethyloxalylglycine preconditioning enhanced the expression of vascular endothelial growth factor (VEGF) among pro-angiogenic factors in cAT-MSCs via hypoxia-inducible factor-1α stabilization. Dimethyloxalylglycine primed-cAT-MSC-conditioned media increased angiogenesis in human umbilical vein endothelial cells. These results suggest that DMOG conditioning of cAT-MSCs augmented the secretion of VEGF, which acted as a prominent pro-angiogenic factor during angiogenesis. DMOG-primed cAT-MSCs may have the potential to induce beneficial effects in ischemic diseases in clinical trials.

Enhanced synthesis de novo of phosphatidylinositol in lymphocytes treated with cationic amphiphilic drugs.

Project description:A variety of amphiphilic cations caused very large increases in the rates of incorporation of Pi and glycerol into phosphatidylinositol in pig mesenteric small lymphocytes. This synthesis de novo of phosphatidylinositol led to a doubling of the phosphatidylinositol concentration in the cells within 3.5 h. The increase in synthesis of phosphatidylinositol labelled with [3H]- or [14C]-glycerol was matched by an approximately equivalent decrease in incorporation of glycerol into phosphatidylcholine, phosphatidylethanolamine and triacylglycerol. Amphilic cations which produced these effects included, in order of decreasing effectiveness, trifluoperazine (half-maximal effect at about 70 mum) greater than chlorpromazine approximately promethazine approximately imipramine greater than cinchocaine greater than amethocaine approximately cetyltrimethylammonium greater than fenfluramine greater than amphetamine greater than 2-phenethylamine greater than cocaine approximately procaine; the most effective compounds were those with the largest and most hydrophobic non-polar substituents. The response to cations was not changed by varying the extracellular Ca2+ concentration in the range 10 nm-1mm. The active amphiphilic cations interacted with anionic phospholipids causing aggregation of aqueous dispersions and/or changes in chromatographic behaviour. These results indicate that amphiphilic cations redirect glycerolipid synthesis de novo, probably owing to inhibition of phosphatidate phosphohydrolase, so that phosphatidylinositol synthesis is increased at the expense of other glycerolipids.
