Embodiment 1

[0064] In Example 1, tissue samples from 39 patients with bladder cancer from Shanghai Renji Hospital, including 23 cases of "gemcitabine / cisplatin resistance group (abbreviation: GC resistance)" and "gemcitabine / cisplatin remission group (abbreviation: GC remission) 16 cases", bladder cancer-related gene sequencing and IHC staining of abnormally expressed proteins were performed. Specimen information is shown in Table 3.

[0069] 1. Taking and saving bladder cancer tissue

[0070] The bladder tissue samples obtained in the present invention are stored at -80°C or in liquid nitrogen. The specimens of each patient were divided into two parts, one part was fixed with 4% formaldehyde, stored at room temperature, and subsequently embedded in paraffin and sectioned; the other part was cut into pieces with tissue scissors and stored at -80 or liquid nitrogen, and subseq...

Abstract

The invention discloses a system for predicting the chemotherapy sensitivity of a patient with bladder cancer. The system comprises a gene detection device, an immunohistochemical detection device anda data processing device, wherein results of the gene detection device and the immunohistochemical detection device are analyzed and processed by virtue of the data processing device; the gene detection device comprises a DNA extraction kit, a primer group, a PCR amplification instrument, a PCR purification kit, a sequencer and an electrophoresis instrument. According to the system, correspondingspecific primers and antibodies are designed and prepared by virtue of bladder cancer mutant genes including FGFR3, HRAS, TERT promoters, TP53, TSC1, PIK3CA and HER2 as well as abnormal expression proteins including EGFR, ERCC1, CK20, BRCA1, CD44, RRM1, PD-L1, TUBB3, Ki67 and CD71, so as to meet the detection requirements of molecular pathological indexes; and the system is simple, convenient, economic and used for guiding the implementation of neoadjuvant chemotherapy, and the prediction accuracy of the chemotherapy sensitivity of the bladder cancer can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of biological genes and immune detection, in particular to a system for predicting chemotherapy sensitivity of bladder cancer patients. Background technique [0002] Bladder cancer (BC) is one of the most common tumors in the urinary system, and its morbidity and mortality rank first among urinary system tumors in my country. Bladder cancer can be divided into papillary non-muscle-invasive bladder cancer and muscle-invasive bladder cancer. The former tends to grow into the bladder cavity and has a high recurrence rate, which can reach 70% after surgery; the latter has a strong The ability to proliferate, invade, and metastasize, fatal metastases can occur in up to 50% of patients. Surgery is the main treatment for bladder cancer. For localized bladder cancer, the prognosis of surgery is good; for non-localized bladder cancer, especially muscle-invasive bladder cancer, surgery alone has a high recurrence rat...
