23 Urethral Cancer
Urethral Cancer 501
According to the experience of the Gustave Roussy Institute, (6,7,16) results for brachytherapy using various treatments are suboptimal, with 5-year survival rates ranging between 30 - 50%. The results vary according to the following parameters: Tumour size: - less than 20 mm: 5-year survival over 60%; - between 20 - 50mm: 40%; - more than 50mm: less than 20%. - Tumour site: survival rate is better for the anterior urethra (50 - 60%) than for the posterior urethra (20 - 30%). 11.3 Complications (in male and female) One of the acute effects during brachytherapy is inflammation, which is usually painful. It can be complicated by local infection ± urinary infection, necessitating antibiotic treatment. These acute effects affect 20 - 30% of male and female patients. (6,11,12) For urethral penile carcinoma treated with brachytherapy, complications are comparable to those observed in penis cancer treated with interstitial implant. But in cases of urethral tumours the risk of secondary strictures is higher. (1,3,6) For females, different complications are encountered: local necrosis, cystitis, urinary incontinence and rarely vagina fistula. (5, 6,12) In both cases, complications leading to permanent sequelae are observed in 25 - 30% of patients. (6,11,12) 12 References 1. Anderson KA, Mc Aninch JW.
