Pathological causes and early diagnosis of bladder carcinoma in situ

Bladder cancer can be classified in detail due to different causes and symptom states. Bladder carcinoma in situ is a special type of cancer. Let the experts take us to understand the pathological causes and early diagnosis of bladder carcinoma in situ. We hope that it will help readers judge and distinguish the types of diseases and take correct countermeasures.

Bladder carcinoma in situ is a special form of transitional epithelial tumor. It is confined to the transitional epithelium of the bladder, forming a villous red flaky plaque that slightly protrudes from the mucosa, rather than a papillary mass, and does not invade the basement membrane. Professor Lu Shiquan, a famous Chinese anti-cancer doctor, said that bladder carcinoma in situ is generally poorly differentiated, and the adhesion between cancer cells is reduced, causing the cells to fall off easily. The positive rate of urine cytology examination is relatively high in clinical practice. Clinically, bladder carcinoma in situ can be divided into two categories: one is primary carcinoma in situ, which is more common in young and middle-aged people, and often presents with bladder irritation symptoms as clinical manifestations. The other is secondary carcinoma in situ or para-cancer carcinoma in situ, which is a carcinoma in situ confirmed by biopsy in the normal or abnormal mucosa around the bladder cancer. Bladder patients with coexisting para-cancer carcinoma in situ generally have a poor prognosis, a high recurrence rate, and the tumor is prone to develop from superficial to invasive.

Since bladder carcinoma in situ often only presents as rough mucosa, slight bulge and mucosal congestion, it is difficult to make a correct diagnosis with imaging examinations such as B-ultrasound and CT, and sometimes it is not easy to find it under direct cystoscopy. Therefore, pathological biopsy is crucial for the diagnosis of bladder carcinoma in situ. According to medical research statistics, the positive rate of urine cytology in patients with bladder carcinoma in situ can be as high as 95%, so urine cytology is very valuable in discovering or judging the presence of carcinoma in situ.

Through the above introduction, I believe that readers have already had some understanding of bladder carcinoma in situ. By understanding the knowledge of bladder carcinoma in situ, I hope that readers can use it reasonably and attach great importance to the signs of cancer so as to obtain timely diagnosis and treatment.
