Description
Technical field
The present invention relates to diagnosing tumor radiopharmaceutical, more particularly to a kind of novel polypeptide radiopharmaceutical of targeting HER2
And its preparation method and application.
Background technology
In worldwide, breast carcinoma still comes first of women's kinds of tumor, and mortality rate is located at second.Mesh
Before, the conventional methods for clinical diagnosis of breast carcinoma includes mammary X-ray photography, color ultrasound and MRI.These Imaging Methods and mammary gland tissue
Biopsy is compared, and with noninvasive advantage, but is also faced with low accuracy rate, shortage specificity, cannot be provided molecular level information
The shortcomings of.Used as the important mode of molecular imaging, PET and SPECT is clinically widely used.They the characteristics of
It is that sensitivity is high, and with accurate quantitative analysis and tumor-related molecules horizontal information can be provided.At present, clinically 25% ~ 30%
All there is the high expression of HER2 albumen in patients with breast cancer cell.The high expression of HER2 is often imply that with high transfer wind
Danger, Tumor Differentiation difference and prognosis be not good.With going deep into for studying to HER2, become mammary gland for the molecular targeted therapy of HER2
The important directions of cancer Therapy study.Herceptin(Trastuzumab, trastuzumab)It is that first, the whole world goes through to be applied to face
The specific humanized monoclonal antibodies of HER2 of bed.Trastuzumab energy specific effects are in the HER2 on breast cancer cell surface
Receptor, and induce immunocyte to kill tumor, the killing to normal cell is less, with high-affinity and targeting, is mammary gland
The representative drugs of cancer molecular targeted therapy.However, not all patient has response to the treatment of Trastuzumab,
Only the breast cancer patients of fraction can benefit from treatment.More seriously, most patient with breast cancer eventually exists
Produce drug resistance in Trastuzumab therapeutic processes, and the somewhat expensive of Trastuzumab immunization therapies, cycle are long.Therefore, build
Vertical new breast carcinoma HER2 targeting nucleus medical image method is for screening patient exactly, accurately monitor curative effect, reasonably
Arrange therapeutic scheme, effectively carry out prognostic evaluation finally to realize that individualized treatment is significant.
The content of the invention
