Abstract:
Objective To evaluate the effects of rigorous surveillance and retroperitoneal lymph node dissection (RPLND) in the treatment of low-risk patients with clinical stage Ⅰ nonseminomatous germ cell testicular tumors (NSGCT) after radical orchiectomy.Methods The data of 71 patients with clinical stage Ⅰ NSGCT were analyzed retrospectively in Hunan Provincial Tumor Hospital,Xiangya Third Hospital of Central South University and Hunan Provincial People's Hospital between Feb,2001 and Apr,2012.Excluding lymphatic and vascular invasion,percentage of embryonal carcinoma＞50％ and increasing tumour markers (AFP/β-HCG) following orchiectomy,46 low-risk patients out of 71 patients with clinical stage Ⅰ NSGCT were selected and divided into rigorous surveillance group (30 cases) and RPLND group (16 cases) according to different therapeutic methods after radical orchiectomy.Univariate analysis was used to confirm variables associated with disease progression,and the disease free survival rates (DFSR) were compared by using Kaplan-Meier analysis.Results Five cases were lost,and 41 cases were followed up for an average of 61 months (range,15-147 months),with 58 months in rigorous surveillance group (range,19-147months) and 65 months in RPLND group (range,15-144 months).The survival rate was 100％ in 2 groups.The DFSR was 89％ (24/27) and 86％ (12/14),respectively,and there was no significant difference between the 2 groups (x2 =0.08,P=0.78).The DFSR was 83％ in patients with small amout of embryonal (percentage of embryonal carcinoma ＜ 50％),and 92％ in patients without embryonal carcinoma,and there was no significant difference between the 2 groups (x2=1.07,P=0.30).Also there was no significant difference between the patients less than 15 years and patients more than 15 years (x2=1.59,P =0.21).Conclusions There is no significant difference in recurrence rate and DFSR between rigorous surveillance group and RPLND group.Low-risk patients with clinical stage Ⅰ NSGCT may achieve satisfactory prognosis with surveillance after radical orchiectomy.
