Objective:
To investigate the effect of surgery on advanced penile cancer without distant metastasis and the factors influencing the prognosis.
Methods:
Between September 2007 and July 2015, we treated 8 cases of advanced penile cancer without distant metastasis by penectomy and lymph node dissection. The patients were aged 37-67 (mean 51.1) years. We followed up the patients for 4-60 (mean 19.25) months postoperatively and analyzed the surgical effects and the factors affecting the prognosis.
Results:
Three of the patients remained alive while the other 5 (62.5%) died at 4-13 (mean 9) months after surgery. No significant complications were observed and myocutaneous flap repair showed good prognosis in 4 of the patients with largearea skin defect.
Conclusions:
Surgery is comparatively a valuable option for the treatment of advanced penile cancer without distant metastasis, though with a poor prognosis, and the important factor affecting its prognosis is lymph node metastasis. Flap repair can solve the problem of largearea skin defect after surgery. However, evidence is not yet sufficient to prove the effectiveness of multimodality therapy of this malignancy.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
