Cancer remains to be the second most common cause of death, and its incidence and mortality rates are increasing in China. According to the 2015 National Central Cancer Registry (NCCR) of China, the incidence of bladder cancer and prostate cancer ranked sixth and seventh, respectively, in male cancers. The majority of prostate cancer patients were diagnosed at an advanced stage. Early diagnosis of prostate cancer is the key to improve prostate cancer survival in China. Radical prostatectomy or radical radiotherapy is the main treatment for localized prostate cancer, and a comprehensive therapy based on androgen deprivation therapy is the treatment for advanced disease. The most common histologic types of bladder cancer in China were urothelial carcinoma, followed by adenocarcinoma and squamous carcinoma. The majority of patients were diagnosed using white-light cystoscopy with biopsy. Fluorescence and narrow-band imaging cystoscopy had additional detection rates and are becoming more popular. Following Chinese guidelines, most non-muscle invasive bladder cancer patients were treated with diagnostic transurethral resection and more than half of the muscle invasive bladder cancer patients were treated with radical cystectomy. Due to the increased detection rate of kidney tumors by ultrasound in physical examination, the number of incidentally diagnosed renal cell carcinoma has increased. Localized kidney cancers are more and more often treated by nephron-sparing surgery. Radical nephrectomy is still the main treatment option for patients with locally advanced renal cell carcinoma. Both laparoscopic and robotic-assisted laparoscopic surgeries have been used in big medical centers. Both testicular cancer and penile cancer have lower incidence levels than that in Europe. As we have an enormous population base, the absolute patient number is big. The diagnosis and treatment follows the Chinese guidelines. In China, both medical professionals and public should concern more on the early diagnosis, as there is not enough cancer prevention information available. Urologists should also take a more active role in educating the population.
Reduced quality of life after cystectomy has made bladder preservation a popular research topic for muscle-invasive bladder cancer (MIBC). Previous research has indicated significant tumor downstaging after neoadjuvant chemotherapy (NAC). However, maximal transurethral resection of bladder tumor (TURBT) was performed before NAC to define the pathology, impacting the real evaluation of NAC. This research aimed to assess real NAC efficacy without interference from TURBT and apply combined modality therapies guided by NAC efficacy. Materials and Methods Patients with cT2-4aN0M0 MIBC were confirmed by cystoscopic biopsy and imaging. NAC efficacy was assessed by imaging, urine cytology, and cystoscopy with multidisciplinary team discussion. Definite responders (≤T1) underwent TURBT plus concurrent chemoradiotherapy. Incomplete responders underwent radical cystectomy or partial cystectomy if feasible. The primary endpoint was the bladder preservation rate. Results Fifty-nine patients were enrolled, and the median age was 63 years. Patients with cT3-4 accounted for 75%. The median number of NAC cycles was three. Definite responders were 52.5%. The complete response (CR) was 10.2%, and 59.3% of patients received bladdersparing treatments. With a median follow-up of 44.6 months, the 3-year overall survival (OS) was 72.8%. Three-year OS and relapse-free survival were 88.4% and 60.0% in the bladdersparing group but only 74.3% and 37.5% in the cystectomy group. The evaluations of preserved bladder function were satisfactory. Conclusion After stratifying MIBC patients by NAC efficacy, definite responders achieved a satisfactory CANCER RESEARCH AND TREATMENT (CRT) 4
