Definitions
- the present invention relates to a biocompatible degradable material composed of a phosphocalcic matrix comprising magnetic particles, said material being useful for the treatment of bone metastases by thermolysis and / or for tracing cancer cells.
- Bone metastases from primary cancers elsewhere in the body are very common, and are even an expected evolution of the disease as the life expectancy of patients increases.
- Bone tissue is one of the three most common sites of cancer metastasis. They are particularly common in the natural history of breast, prostate, lung, kidney and thyroid cancers. They are, radiologically in most cases, a gap due to the strong osteolytic activity that is manifested in their periphery. This osteolysis is clinically associated with bone pain and long bone fractures or vertebral body compression. The prognosis of bone metastases remains very dark and their treatment is palliative. Prolonged survival can nevertheless be obtained depending on the characteristics of the primary tumor.
- metastases are classified into osteolytic, mixed osteoblastic and intertrabecular tumors.
- the most common type is the mixed type in which a bone resorption zone coexists with a regeneration zone on the periphery of the first.
- Metastases consist of cell clusters between trabeculae or remnants of trabeculae. At the cellular level, there is a large polymorphism and many atypical cells with many mitotic images. They are surrounded by bone tissue showing many signs resorption in the form of numerous Howship gaps with active osteoclasts.
- the cells constituting these cell clusters come from the migration of cells of the primary tumor which are fixed in the bone tissue because they find favorable conditions for their development. Bone metastases can also be classified into different stages of development: onset phase, interaction phase, and carcinoma phase. They are most often diagnosed during the interaction phase, that is to say when the tumor cells activate the formation and the activity of osteoclasts which are the cells responsible for bone resorption. It appears that tumor cells collaborate with stromal cells and osteoblasts for recruitment of osteoclasts through the RANK-RANKL system (Kitazawa, S., and Kitazawa, R., RANK ligand is prerequisite for cancer-associated osteolytic lesions J Pathol, 2002: 198; 228-236).
- the objective of the invention is the treatment of bone metastases. It eliminates cancer cells to limit the progression of the disease and to abolish osteoclast stimulation without, as far as possible, destroying the bone regeneration capacity at the periphery of the tumor. The elimination of cancer cells leads clinically to a reduction of pain and a lower risk of fracture.
- Radiotherapy is not without risk, especially when the metastasis is located near a noble organ, lung, central nervous system ...
- the problem of these treatments comes from the concomitant elimination of cells involved in bone regeneration.
- the particles once phagocytées or intemalised by the cells can have a specific toxicity thanks to the active principle that they convey and they release in the cell. They can also be heated in a high frequency magnetic field and induce direct thermolysis or indirectly by sensitization of cells heated to radio or chemotherapy. The major obstacles to this type of therapy come from the more or less specific specificity of the addressing of the particles.
- thermocytolysis The efficiency of particles in thermocytolysis is related to their contact with cells.
- Non-cell-bound particles are much less effective (Bacri, JC, Fatima Da Silva, M., Perzynski, R., Pons, JN, Roger, J., Sabolovic, D., Halbreich, A., Use of magnetic Nanoparticles for thermolysis of cells in a ferrofluid in: Hafeli, U., Schult, W., Teller, J., Zborowski, M., (eds) Scientific and clinical applications of magnetic carriers Plenum Press New York 1997, pp 597-606).
- the cells of the mononuclear phagocyte system present in the blood and many tissues are capable of phagocyting particles up to a size of about forty microns. Other cells have much more limited phagocytosis capabilities.
- a system for injecting into a tumor a paste containing a mineral suspension from which will precipitate a sulfate or a calcium phosphate containing small magnetic particles dispersed in the matrix formed mineral that will be released as the degradation of it.
- the role of the matrix is to contain the particles in the injection zone, keep them separated from each other and release them in contact with the tumor cells in a defined kinetics. The released particles will then enter the tumor cells by endocytosis.
- the matrices of phosphates and calcium sulphates have a good bone biocompatibility. They are, for the most part, capable of being totally integrated into the bone tissue without causing a significant foreign body reaction. They are then degraded at variable speeds according to their chemical composition and their physico-chemical characteristics and totally replaced by bone tissue. These matrices are injected into the bone in the form of a paste from which it precipitates a phosphate or calcium sulfate compound different from that which is suspended in the paste. The entanglement of the crystals of the precipitate ensures the setting of the material and its mechanical strength which can be close to that of the cancellous bone in a few hours to a few days (T.
- the magnetic particles can be heated in an electromagnetic field before or after entering the cells. This heating can be repeated the number of times necessary without requiring another injection.
- the magnetic particles are, in fact, released over several days to several weeks from the mineral matrix. When the cells are thermolysed, the particles they contain are added to those that have just been released from the matrix to be phagocytosed by new cells. In addition, these particles acting at the heart of the tumor do not hinder the bone regeneration existing in the periphery of bone metastases.
- the invention relates to a biocompatible degradable material characterized in that it is composed of a phosphocalcic matrix and / or calcium sulphate or a degradable biocompatible polymeric matrix, said matrix containing magnetic particles, said material being in the form of a paste when introduced into the body and in solid form later. The particles are released as and when degradation of the cement constituting the matrix in which they are trapped.
- phosphocalcic matrix is meant a mixture comprising one or more phosphates selected from the group of amorphous calcium phosphates, weakly crystalline apatitic phosphates, anhydrous dicalcium phosphates or dihydrates, tricalcium phosphates, monocalcium monohydrate phosphates, pyrophosphates, octocalcium phosphates or hydroxyapatite.
- the phosphocalcic matrix is rapidly resorbable, that is to say within a few days to a few weeks, which implies a solubility corresponding to that of dicalcium phosphate.
- the matrix may also consist wholly or partly of calcium sulphates which exhibit biocompatibility and degradation characteristics which are also compatible with the applications of the material for the treatment of bone tumors.
- a material according to the invention is a mineral material introduced in the form of paste. When taking, the precipitation of a phase is not in the suspension or is a minority in the latter. The first histological signs of resorption (notches, partial fragmentation) are visible under the microscope a few days after its introduction, and the radiological disappearance occurs between 4-52 weeks following the composition of the mineral phase, preferably 8 weeks for calcium sulphate matrices. .
- said material may be composed of a degradable polymeric matrix containing magnetic particles. It can be constituted by a natural or artificial biodegradable polymer, such as collagen, polylactic and glycolic acids, polydioxanone, polyfumarate, polyanhydrous, polyorthoesters, polyurethanes, polyphosphazenes, polycaprolactone, polyhydroxybutyrate, polyhydroxyvalerate, polyvalerolactone, polytartronic acid and polymalonic acid.
- the material may be in the form of gel, foam or paste.
- magnetic particles particles containing a metal, especially iron, preferably in the form of ferrites: magnetite or maghemite or any other ferro, ferri, meta or antiferromagnetic inorganic material. They are preferably made of ferrite (Fe 2 O 3 ) or magnetite. They may be in the form of an organo-mineral composite. The magnetic mineral constituting the core of the particle is surrounded by a layer of an organic compound.
- Metal particles can be obtained by hydrothermal synthesis in a stirred reactor by injecting 80 ml of a FeCl 2 solution calculated to be able to synthesize 5 g of magnetite, then 170 cm3 of fresh water containing 10 g of NaOH are added. Under nitrogen flow (301 / h) the solution is heated to 80 ° C. When this temperature is reached, the nitrogen is replaced by compressed air at the same flow rate for 20 hours. The ferrites are then washed with water and then with ethanol before being dried.
- the magnetic particles have a particle size of between 0.001 ⁇ m and 0.01 ⁇ m, or else between 0.05 ⁇ m and 0.1 ⁇ m, for example 0.07 ⁇ m, 0.15 ⁇ m, 0.5 ⁇ m. They may, however, have a size of about one micron for particular applications, for example a particle size of between 0.1 and 10 microns.
- Such a material thus forms a mineral matrix releasing the magnetic particles in a kinetics compatible with their internalization by the cells of the surrounding tissues.
- the material of the invention may reside in an association with a mineral or organic matrix of magnetic particles or iron particles coated with a mineral layer, preferably phosphate, sulphate or calcium carbonate.
- This coating may also contain a fluorescent element such as Europium.
- said particles consist of an organomineral composite containing a core of iron, ferrite or any other magnetic compound coated with polymer in the form of a thin layer or in the form of polymer chains having a free end.
- said magnetic particles are vectors of a molecule used in chemotherapy or an isotope.
- the invention in a second aspect, relates to a process for preparing said material comprising mixing a powder of magnetic particles with a phosphate mineral powder or a calcium sulfate in aqueous solution until a paste is formed, and in a hardening of said dough for a few minutes to a few minutes hours.
- This process may further comprise a step of preparing said particles by hydrothermal synthesis in a reactor by injecting a solution of FeCL 2 into a reactor, adding fresh water containing NaOH, the mixture being put under nitrogen flow and brought to a temperature of between 50 ° C. and 100 ° C., the nitrogen is replaced by compressed air until ferrites are obtained.
- the invention relates to the use of a material described above for the preparation of a medicament or medical device for the treatment of bone tumors. More particularly, this medical device allows the targeted thermolysis of cancer cells. This is made possible by means of magnetic particles which are capable of inducing hyperthermia in the tissues in which they are released.
- the magnetic particles are, in fact, released over several days to several weeks from the phosphocalcic matrix. When the cells are lysed, the particles they contain are added to those that have just been released from the calcium matrix to be phagocytosed by new cells. On the other hand, these particles acting at the heart of the tumor do not hinder the bone regeneration existing in the periphery of bone metastases.
- the invention relates to a method of diagnosis of bone cancer extension comprising the use of magnetic particles as tracers of tumor cells detectable in MRI and the tracking of cells in migration to be able to treat sites at stages. subclinical. It should be noted that for cell tracing, larger iron oxide particles ( ⁇ 0.5 ⁇ m) produce a stronger signal (Hinds, KA, et al., Highly efficient endosomal labeling of progenitor and stem Blood cells, 2003).
- the invention also relates to a method for tracing in MRI, electron microscopy, focal or fluorescence of the cells having ingested said particles after release from a degradable and biocompatible material described above.
- CaSO 4 composition 2H 2 O: 96% CaCO 3 .MgCO 3 : 2, 1% Fe 2 O 3 .Al 2 O 3 : 0.5% SiO 2 : 0.4%
- Example 3 Endocytosis of the Magnetic Particles 1 mg of the previously described magnetic particles of 0.07 ⁇ m particle size was introduced into a culture of primary line of bone metastatic cells in order to verify the ability of these cells to phagocyte the particles.
- the cell line was obtained from a bone metastasis biopsy of a breast adenocarcinoma during an intervention for osteosynthesis. The cells contained in the biopsy were dissociated by incubation for two hours at 37 ° C in a collagenase solution in isotonic phosphate buffer.
- the cell suspension was then centrifuged, resuspended in 2 ml of DMEM culture medium supplemented with 5% fetal calf serum and introduced into a culture flask at a density of 10 5 cells / ml.
- the cells were cultured for three days to a pre-confluence stage. They then form a carpet leaving a space between the cells some of which are spherical thus marking a high proliferation.
- 1 mg of powder is then suspended by stirring in 1 ml of culture medium and 0.5 ml is introduced into the culture flask in which it is diluted by the addition of 3 ml of culture medium. The cells were then incubated at 37 ° C for 48 hours.
- the cells are observed by inverted optical microscopy then the bottom of the box is scraped and the collected cells are dehydrated, included in an epoxy resin.
- Sections of 250 amstrong are made and observed by transmission electron microscopy.
- Optical microscopy reveals particles of different sizes (particle agglomerate) within the cytoplasm of the cells.
- the electron microscopic sections show that the cytoplasm contains numerous lysosomal-type vesicles filled with one or more metal particles. Between 10 and 30% of the sectional areas of the cells are occupied by particles.
- Example 4 Test of the different granulometries 1 mg of magnetic particles previously described was introduced into a primary line culture of the same metastatic bone cell line in order to verify the ability of these cells to phagocyte the particles.
- the particles have four different particle sizes: 0.07 ⁇ m, 0.15 ⁇ m, 0.5 ⁇ m.
- the cell line was obtained from a bone metastasis biopsy of a breast adenocarcinoma. The cells contained in the biopsy were dissociated by incubation for two hours at 37 ° C in a collagenase solution in isotonic phosphate buffer.
- the cell suspension was then centrifuged, resuspended in 2 ml of DMEM culture medium supplemented with 5% fetal calf serum and introduced into a culture flask at a density of 10 5 cells / ml.
- the cells were cultured for three days to a pre-confluence stage. They then form a carpet leaving a space between the cells some of which are spherical thus marking a high proliferation.
- 1 mg of powder of each sample is then suspended by stirring in 1 ml of culture medium and 0.5 ml is introduced into a culture flask in which it is diluted by the addition of 3 ml of culture medium. Each test is repeated three times.
- the cells were incubated at 37 ° C for 48 hours. The cultures are then examined by inverted optical microscopy and transmission electron microscopy.
- Example 6 Delivery of Magnetic Particles to Cells by In Vivo Matrix
- Four adult sheep were anesthetized and a hole 4 mm in diameter and 5 mm long of the right external condyle was made. The hole was then filled with a paste made of plaster of Paris containing 2 mg of magnetic particles per ml of mixing solution.
- Two sheep were euthanized at two weeks and the other two at four weeks.
- the condyles were removed, dehydrated in ethanol and included in polymethyl methacrylate blocks. Sections 7 ⁇ m thick were made, stained with a Giemsa solution and observed under light microscopy. At two weeks, there is an early resorption of the material which is surrounded by loose connective tissue.
- the macrophage cells in contact with the material contain birefringent mineral particles as well as particles black magnets that make a tattoo of the cytoplasm. It should be noted that connective cells that do not have the morphological characteristics of macrophages also show a tattooed cytoplasm. At one month, the implant disappeared and a large part of the section area previously occupied by the implant is invaded by bone trabeculae. The interfrabecular space is occupied by a loose connective tissue of which all the cells are tattooed by the magnetic particles. The transmission microscopy study confirms that many cells around the implant contain metal particles.
