Method of treating choroidal melanoma with size of more than 6,5 mm
SUBSTANCE: invention relates to medicine, particularly to ophthalmology. What is involved is a brachytherapy of an intraocular melanoma with a size of more than 6.5 mm by anchoring a beta-applicator with ruthenium-106 +rhodium-106 to an episclera for 7-14 days on a projection of the melanoma at total radiation dosage 3000 Gy. The brachytherapy is combined with a diode-laser transpupillar therapy of the melanoma at radiation power 800 mWt. Then, 6-12 months after the beta-applicator has been removed, a restrictive retinal coagulation at power 500 mWt and an endoresection of the residual melanoma follow. The method enables avoiding such complications, as vitreous body and retina haemorrhage, retinal detachment, complete loss of vision, as well as reducing a probability of metastases due to the preliminary brachytherapy and the following restrictive retinal laser coagulation.
EFFECT: combined application of the thermal therapy and brachytherapy enables affecting the melanoma from both sides for more complete destruction of its structure.
The invention relates to medicine, in particular to ophthalmology.
Melanoma of the choroid is a severe disease that is difficult to treat, ends with different degrees of intensity of vision, leading to blindness and even death of the patient.
Disease intraocular melanoma currently in Moscow is 13.3 cases per 1 million adults. In the get it from 6,23 up to 8 people to 1 million people.
Melanoma in the developing choroid usually sporadic. This is evidenced by chromosomal changes found in patients with melanoma.
The bulk of melanomas (57%) are localized postequalization, 26% Equatorial 17% prekatrina.
Eyes with intraocular melanomas large size (greater than 6.5 mm) often nuclearwaste due to the limited capacities of the impact on melanoma and the potential for metastasis.
The closest analogue is a method of treating melanoma comprising andarticle intraocular melanoma with its preliminary heat for 2-3 days before surgery (British Journal of Ohtalmolodgy. August 2008 vol 92, No. 8, str-1049).
However, this method has significant drawbacks. During and after surgery and there are many complications: hemorrhage, retinal detachment, total loss of vision, and there is a possibility METAS is aerovane.
The objective of the invention is to provide an effective method for the treatment of intraocular melanoma of large size.
The technical result is the reduction of complications such as hemorrhage, retinal detachment, total loss of vision, as well as reducing the likelihood of metastasis.
The technical result is achieved in that in the method of treatment of intraocular melanoma larger than 6.5 mm, including her therapy and interesection, according to the invention, first produced brachytherapy by filing for episclera for 7-14 days on the projection melanoma beta-applicator with radionuclide Ru-106 + Rhodium-106, with a total dose of 3000 G, in parallel with brachytherapy transpupillary produce diode-laser transpupillary therapy of melanoma with radiation power of 800 mW to the maximum coating its surface coagulates, 6-12 months after withdrawal of beta-applicator transpupillary produce restrictive laser coagulation of the retina with the capacity of 500 mW and then andarticle residues melanoma.
Brachytherapy radiation load on the sclera up to 3000 Gr and transpupillary thermotherapy could destroy the structure of melanoma fully or partially, to form a chorioretinal scar, and thus, to avoid complications such as retinal detachment, hemorrhage in the retina and is clonidne body and dissemination of melanoma.
According to the invention, prior brachytherapy before andarticle melanoma and the formation of a chorioretinal scar allows operation in a more "comfortable" conditions, to avoid complications such as retinal detachment, hemorrhage into the vitreous body.
Restrictive laser coagulation of the retina with the capacity of 500 mW is done with the purpose of prophylaxis of retinal detachment with subsequent andarticle melanoma.
therapy allows to destroy the top of melanoma to 3 mm, thus, the impact on melanoma comes from two sides: therapy from the top, and brachytherapy from the base, allowing you to more fully destroy the structure of the melanoma, and andarticle residues melanoma allows you to completely remove it.
The method is as follows.
The first stage was performed brachytherapy by filing for episclera for 7-14 days on the projection melanoma beta applicator with radionuclide Ru-106 + Rhodium-106, with a total dose of 3000 G, in parallel with brachytherapy transpupillary produced the diode-laser transpupillary thermotherapy radiation power of 800 mW to the maximum coating its surface coagulates. 6-12 months after withdrawal of beta-applicator transpupillary produced restrictive laser coagulation of the retina with the capacity is 500 mW
Then ran Subtotal vitrectomy technology 25 G. were removing modified vitreous body. Then one sclerotomies puncture was expanded to 20 G and using tiglapsetag tweezers took the plot of melanoma for histological study. Next, using vitrectomy performed a complete resection of melanoma, then the vitreous cavity was temporaroly gas. If patients secondary retinal detachment produced tamponade vitreal cavity silicone oil.
Control examination was performed one week, one month, 3 months and ultrasound on the subject of metastasis every 6 months.
Histological and cytological examination showed that the resulting material live tumor cells was not detected.
Clinical example: patient 52 years have complained of decreased vision in his left eye. After ophthalmological and General surveys of distant metastases not detected. Diagnosed and intraocular melanoma of the left eye and the lower outer segment according to the In - scan reached the height of 8.0 mm, base 10.3 mm Patient produced treatment: brachytherapy + transpupillary thermotherapy. 12 months regressed melanoma and its height residue was 5.8 mm diameter 9.1 mm, formed chorioretinal the scar. Then made restrictive laser coagulation of the retina with the capacity of 500 mW and andarticle residues melanoma to the sclera. The observation period of 5 years. Distant metastases no.
Method for the treatment of intraocular melanoma larger than 6.5 mm, including her therapy and interesection, characterized in that the first produce brachytherapy by filing for 7-14 days to episclera on the projection melanoma beta applicator with radionuclide Ru-106 + Rhodium-106, with a total dose of 3000 G, in parallel with brachytherapy transpupillary produce diode-laser transpupillary therapy of melanoma with radiation power of 800 mW to the maximum coating its surface coagulates, 6-12 months after withdrawal of beta-applicator transpupillary produce restrictive laser coagulation of the retina with the capacity of 500 mW and then andarticle residues melanoma.
