The clinical significance of Sentinel lymph node biopsy in N0 penile cancer
Background and purpose: The inguinal lymph node dissection of penile cancer after resection of the primary lesion has been controversial
this paper aimed to preliminary study the feasibility and clinical significance of sentinel lymph node biopsy (SLNB) in pN
0
stage patients with penile cancer. Methods: We analyzed retrospectively the clinical data of 25 patients of pN
0
penile cancers admitted in our department from Mar. 2004 to Aug. 2012
all the patients used the methylene blue for SLNB after having resection of the primary lesion
at the same time received modified inguinal lymph node dissection (ILND). Results: The sentinel lymph node (SLN) of 24 patients had be actually detected
the success rate was 96%
(24/25)
7 was positive
17 was negative; The accuracy was 95.8% (23/24)
sensitivity was 87.5% (7/8)
false negative rate was 12.5% (1/8)
and no false positive. There is a high degree of consistency between the SLNB grope and the routine grope (Kappa value=0.903
P0.01). Conclusion: SLNB for pN
0
stage penile cancers without swollen lymph node had still important guiding significance.
