Xu L, Yang R, Gan W, Chen X, Qiu X, Fu K, Huang J, Zhu G, Guo H - BMC Urol (2015)

Bottom Line: Of the 98 remaining patients, 16 and 82 patients were included in the Xp11.2 translocation and non-Xp11.2 translocation groups, respectively.During the median follow-up of 36 months (range: 3-71 months), the number of cancer-related deaths was 4 (4.9%) and 3 (18.7%) in the non-Xp11.2 translocation and Xp11.2 translocation groups, respectively.The Kaplan-Meier cancer specific survival curves revealed a significant difference between non-Xp11.2 translocation RCCs and Xp11.2 translocation RCCs in young adults (P = 0.042).

ABSTRACT

Background: Little is known about the biological behavior of Xp11.2 translocation renal cell carcinomas (RCCs) as few clinical studies have been performed using a large sample size.

Methods: This study included 103 consecutive young adult patients (age ≤ 45 years) with RCC who underwent partial or radical nephrectomy at our institution from 2008 to 2013. Five patients without complete clinical data were excluded. Of the 98 remaining patients, 16 and 82 patients were included in the Xp11.2 translocation and non-Xp11.2 translocation groups, respectively. Clinicopathologic data were collected, including age, gender, tumor size, laterality, symptoms at diagnosis, surgical procedure, pathologic stage, tumor grade, time of recurrence and death.

Results: Xp11.2 translocation RCCs were associated with higher tumor grade and pathologic stage (P < 0.05, Fisher's exact test). During the median follow-up of 36 months (range: 3-71 months), the number of cancer-related deaths was 4 (4.9%) and 3 (18.7%) in the non-Xp11.2 translocation and Xp11.2 translocation groups, respectively. The Kaplan-Meier cancer specific survival curves revealed a significant difference between non-Xp11.2 translocation RCCs and Xp11.2 translocation RCCs in young adults (P = 0.042).

Conclusions: Compared with non-Xp11.2 translocation RCCs, the Xp11.2 translocation RCCs seemingly showed a higher tumor grade and pathologic stage and have similar recurrence-free survival rates but poorer cancer-specific survival rates in young adults.

Cancer-specific survival (a) and recurrence-specific survival (b) analyses were computed comparing non-Xp11.2 translocation renal cell carcinomas (RCCs) with Xp11.2 translocation RCCs in young adults. Red line: non-Xp11.2 translocation RCC; blue line: Xp11.2 translocation RCC

Fig1: Cancer-specific survival (a) and recurrence-specific survival (b) analyses were computed comparing non-Xp11.2 translocation renal cell carcinomas (RCCs) with Xp11.2 translocation RCCs in young adults. Red line: non-Xp11.2 translocation RCC; blue line: Xp11.2 translocation RCC

Mentions: The number of cancer-related deaths was 4 (4.9 %) and 3 (18.7 %) in the non-Xp11.2 translocation and Xp11.2 translocation groups, respectively. Analyses of CSS curves indicated that Xp11.2 translocation RCCs were significantly more frequently associated with a poorer outcome than non-Xp11.2 translocation RCCs (P = 0.042, Fig. 1a).Fig. 1
