Description

Radiotherapy protective device for primary testicular lymphoma

The technical field is as follows:

the invention belongs to the technical field of primary testicular lymphoma radiotherapy equipment, and relates to a medical protection device for fixing healthy testicles and protecting surrounding skin and organs when performing preventive electron ray radiotherapy on healthy testicles (refuges) after postoperative auxiliary chemotherapy of primary testicular lymphoma, in particular to a primary testicular lymphoma radiotherapy protection device which is convenient and flexible to use and accurate in positioning.

Background art:

lymphoma (lyphoma) is one of the most common malignant tumors in China, and according to data published by the national cancer center, the diagnosis incidence rate of the lymphoma in China in 2014 is 5.94/10 ten thousand; the pathological types of the lymphoma are complex, the treatment principles are different, the radiation therapy is an important component of the comprehensive treatment of the lymphoma, and how to select the radiation beam, the radiation field and the dose in the implementation is determined by the treatment purpose and the diagnosis and treatment conditions of specific cases.

The most common pathological type of primary testicular lymphoma is Diffuse Large B Cell Lymphoma (DLBCL), accounting for 80% -90%. The latter accounts for 3% -9% of testicular tumors and 1% -2% of NHL, and is the most common testicular malignancy in men over 60 years old, with the median age of onset being about 65 years old. The clinical manifestations are as follows: most of them are manifested as painless swelling or tumescence of the testis, and few are manifested as pain of the scrotum. The proportion of patients affected by both testicles at the same time in diagnosis is about 20%, and as many as 35% of patients are easy to relapse after the invasion of the testicles at the opposite side or the auxiliary treatment in the course of disease; postoperative pathology is the gold standard for diagnosis, the disease has no standard treatment scheme at present, tumor local excision plus chemotherapy +/-local radiotherapy is adopted overall, and the 4-year survival rate of chemoradiotherapy combined patients is about 50% -90%; testicular lymphoma is easy to metastasize, common metastasis/recurrence sites are healthy testis (another healthy testis in human body), central nervous system, abdominal lymph node, skin, etc., and prophylactic intrathecal injection is used for preventing recurrence of central nervous system, while healthy testis radiotherapy is used for preventing recurrence of testis due to the existence of blood-testis barrier, and chemotherapy drugs are difficult to prevent.

In the specific clinical diagnosis and treatment process, PET/CT staging, curative effect evaluation, treatment scheme formulation and the like are mostly adopted, the specific part and range of radiotherapy are determined according to the clinical staging of a patient, if the patient only suffers from unilateral testicle disease, namely Ann-Arbor staging is IE stage, after postoperative adjuvant chemotherapy, the patient is given protective radiotherapy to the healthy testicle, and the radiotherapy part of the IIE stage patient comprises the healthy testicle and the preventive radiotherapy to the pelvic lymph node area. When preventive radiotherapy is carried out on healthy lateral testicles, high-energy electronic wires are mostly adopted for single front field irradiation, the electronic wires with the energy of 12Mev or 15Mev are selected according to the size of the testicles, the irradiation fields cover the healthy lateral testicles, scrotum of middle-aged and old people is loose, the testicles are oval, the position of the testicles can be changed every time, the testicles can move, the testicles are theoretically free of irradiation, little or no irradiation is carried out on the surrounding normal skin, but the irradiation is difficult to achieve clinically, and in order to avoid the irradiation, a lead stop block with the inner diameter far larger than that of the testicles is mostly adopted for protection, so that more surrounding normal thigh skin and part of penis can be irradiated unnecessarily; furthermore, the testis can move, so that continuous and accurate irradiation cannot be ensured, and the treatment effect is difficult to ensure.

In the prior art, a Chinese patent with publication number CN206473435U discloses a radiation-proof and scrotum fixing device used after prostate cancer I125 particle implantation and orchidectomy, which comprises a pair of lead briefs, a scrotum support and a waistband, the scrotum support is arranged at the inner side of the lead briefs, the front end of the scrotum support and the rear end of the scrotum support are respectively fixed at the outer side of the lead briefs, the waistband is fixed at the upper end of the outer side of the lead briefs, the device is a radiation-proof and scrotum fixing device used after prostate cancer radioactive particle implantation combined orchiectomy, which has the functions of fixing and supporting, is convenient to operate and has clinical practical value, is easy to be popularized and used in clinic, but the radiation therapy can not be used for exposing the testis during radiation therapy of healthy testis and strong side of primary testicular lymphoma, and the radiation therapy of the testis under the premise of protecting organs around the testis can not be realized; publication number CN 206714860U's chinese patent application discloses a scrotum fixing device for urology department, including fixed waistband, fixed waistband's front end is equipped with first opening, first open-ended one side fixed mounting has first magic circle hair to paste, first open-ended opposite side fixed mounting has first magic thorn to paste, fixed waistband's surface both sides fixed mounting has the connection button, the connection button has the suspender through connecting hole swing joint, the lower fixed surface of suspender is connected with U type connecting band, the lower fixed surface of U type connecting band is connected with the shank fixed band, the surface of shank fixed band is equipped with the second opening, the inside fixedly connected with inflatable packer of shank fixed band. This scrotum fixing device for urological department passes through the structural style that suspender and fixed waistband combine, has used inflatable packer in addition, has not only solved the fastness problem, but also has improved comfort level and adaptability, can make things convenient for patient's recovery greatly, and the device has played fixedly to the scrotum, but is unsuitable for strong side testicle preventive radiotherapy.

In summary, there is no existing medical device for fixing the healthy testis and the healthy testis during the radiation therapy of primary lymphoma of testis and preventing the damage of the testis and the skin and organs around scrotum, and at present, the healthy testis is directly irradiated during the radiation therapy, so that the damage to the organs around the testis is large, and the healthy testis moves during the radiation therapy, which makes it difficult to realize the continuous therapy aiming at the fixed position and reduces the therapeutic effect; the existing scrotum fixing equipment is not suitable for fixing the healthy testicle and carrying out radioactive therapy, and can not protect organs around the testicle irradiated by the rays.
