Description
Technical field
The utility model relates to a kind of device of antitumor susceptibility test, specifically, relates to a kind of test kit for the detection of carcinoma of the pancreas susceptibility.
Background technology
Malignant tumour is serious harm human life and healthy common disease and frequently-occurring disease, is to cause one of disabled and early dead principal disease, and in 35～59 years old age group, malignant tumour occupies first of the cause of the death.Data shows that sending out case load China's malignant tumour year is 2,000,000, and is dead about 1,500,000, and with 3% speed increase and be rejuvenation trend, occupy mortality ratio in all kinds of diseases.
The world comprises operation, radiotherapy, chemotherapy, endocrine therapy and biological immune treatment etc. to the main treatment means of malignant tumour at present.In many means for the treatment of malignant tumor, chemotherapy is as a kind of methods for the treatment of of general, might farthest kill tumour cell in patient's body than additive method, and therefore, chemotherapy is occupied important status in treating malignant tumor.Along with the development of medical science, chemotherapy no longer has been the means that play the palliative therapy effect merely, from appeasing to the radical cure transition.
1998, the World Health Organization proposes, use suitably, chemotherapy has become the radical treatment means that can cure tumour in part tumour (malignant trophoblastic tumor, acute lymphoblastic leukemia, Hodgkin lymphoma, non-Hodgkin lymphoma, carcinoma of testis, acute myeloblastic leukemia, embryonal rhabdomyosarcoma, skin carcinoma, small cell lung cancer and ovarian cancer etc.).After adjuvant chemotherapy, can mammary cancer, osteogenic sarcoma, large bowel cancer, osteosarcoma, retinoblastoma, soft tissue sarcoma and the nephroblastoma etc. be arranged curable tumour.
Carcinoma of the pancreas is that a kind of grade malignancy compares tumors of higher.Multiplely be born in the elderly, developed country's sickness rate is higher than developing country.Along with the change of China's growth in the living standard and dietary structure, the sickness rate of carcinoma of the pancreas presents the trend of rising in recent years, and the tendency of rejuvenation is arranged.
Chemotherapeutical purpose be prolong lifetime, the quality of making the life better and improve the effect of other treatments such as operation, comprise postoperative adjuvant chemotherapy and at the chemotherapy of appeasing of not accepting the radical treatment patient.In recent years, at some big pancreas centers, be that the new adjuvant chemotherapy of purpose also has more application to improve surgical result or to improve the excision rate before the art.
Although chemotherapy is occupied important status in the treatment of malignant tumour, in clinical practice, the result is often not fully up to expectations.Wherein, it is the common factor that causes the chemotherapy of tumors failure that tumour cell produces resistance to chemotherapeutics, also is the key difficult problem of puzzlement oncotherapy.The resistance problem is very general clinical problem, estimates according to American Cancer Society, and the patient because of tumor mortality more than 90% is being subjected to the resistance influence in varying degrees.
Drug resistance of tumor cell is divided into primary and acquired resistance two big classes.Common way is clinically at present, follow the card result of study according to the test of international clinical tumor, learn that different chemotherapeutics is to different tumor treatment susceptibility differences, be that each tumour has corresponding effective chemotherapy medicament sensitive spectrum, thereby the scheme for combining of selecting the single medicine of the highest chemotherapy of curative effect or multiple medicine to form is treated.But often run into such situation clinically, be known as the effective treatment plan of certain tumour through following card research, and the patient who has is had no effect.Be a kind of medicine with milestone significance as Zorubicin to infiltrative breast carcinoma, but still have 50% infiltrative breast carcinoma patient insensitive to this medicine.And for example be good for and select, the curative effect that carcinoma of the pancreas is generally acknowledged is obvious, but also has the patient's curative effect more than 60% also not obvious.
Tumour exists tangible individual difference to various chemotherapeutics.Be different tumor types or the different patients of same type, even same patient is in the different morbidity stages, to the susceptibility of chemotherapy and incomplete same, the result for the treatment of difference is also very big.So far the combined utilization that does not also have a kind of chemotherapeutics or several chemotherapeutics can be effective to a certain tumour 100%.Clinically, use with a kind of chemotherapeutics or with the different tumour patient of a kind of chemotherapy regimen treatment, obviously have certain blindness.Therefore, carrying out the tumour drug sensitive test at different patients before chemotherapy selects effective chemotherapeutics to carry out chemotherapy to seem very necessary.For this reason, set up a kind ofly as the bacterium sensitization test, by sensitivity testing method relatively reliably, different patients is accurately screened responsive chemotherapeutics, and determine its dosage, really realize clinical personalized medicine.
Tumour drug sensitive test is at present operated required medicine to face with now joining, and the tumour drug sensitive test need be tested multiple antitumor drug, and the soup prepared and diluted is loaded down with trivial details, and the required antitumor drug dosage of tumour drug sensitive test is little, sampling inconvenience.The part drug solution following shelf time of state is short, and remainder can only be scrapped, and causes the waste of medicine, especially expensive medicine.
CN93111551.5 discloses tumour chemotherapy medicament sensitive pretest agent compounding method and test kit, and this patent is pre-installed on 8 kinds of antitumor drugs commonly used in the specimen bottle by setting dosage.But this method is not easy to the test of Combination chemotherapy, and is not easy to the dose titration of scheme.
CN03102260.X adopts the method for prefabricated medicine sensitive detecting plate, and antitumor drug is added in the check-out console by calculating dosage, and freeze-drying, packing are used for the tumour drug sensitive test.This method is not easy to the test of Combination chemotherapy equally, and is not easy to the dose titration of scheme.
Clinical have the method for the interim preparation of a small amount of employing antitumor drug to carry out the antitumor drug antibiotics susceptibility test at present, and still, there are many problems in this method: accurate concentration the unknown of compounding pharmaceutical, and the accuracy of institute's preparating liquid leaves a question open; The antitumor drug antibiotics susceptibility test of clinical oral administration antitumor drug can't carry out; The individual operations error is big.
For the ease of the operation of tumour drug sensitive test and save cost, we will various carcinoma of the pancreas antitumor drugs commonly used be prepared into, and dosage is accurate, good stability, can be in tumor cell culture liquid rapidly-soluble aseptic medicine film.And the medicine film cut into slices packing accurately by using dosage.
