Penile cancer is a rare malignant tumor, which often occurs in the inner plate of prepuce and glans. Squamous cell carcinoma is the most common pathological type. Lymph node metastasis is a crucial factor that leads to poor prognosis of penile cancer. The 5-year OS of penile cancer patients without lymph node metastasis is 90%. Still, it goes down sharply in patients with inguinal lymph node metastasis and pelvic lymph node metastasis, which is 50% and 0%, respectively. Using neoadjuvant chemotherapy to treat patients with locally advanced penile cancer (T4, any N stage, or any T stage, N3) may improve their prognosis. TIP (Paclitaxel + Ifosfamide + Cisplatin) regimen is the first line neoadjuvant treatment recommended by NCCN guidelines. Epidermal growth factor receptor (EGFR) plays a vital role in the development of penile cancer. It's also an important therapeutic target for penile cancer. PD-1 is an immune checkpoint molecule on the surface of T cells. In recent years, immune-checkpoint inhibitors targeting PD-1 have shown good efficacy in a variety of tumors. Some phase II / III clinical trials have shown that PD-1 inhibitors can improve the prognosis of patients with lung squamous cell carcinoma, head and neck squamous cell carcinoma and cervical cancer. Previous studies have found that PD-L1 is highly expressed in 40% - 60% of penile cancer, suggesting that penile cancer patients may benefit from immunotherapy. The management of penile cancer with lymph node metastasis is difficult, especially for N2-3 stage. This phase II study aim to explore an effective combination therapy for locally advanced penile cancer. 29 patients need to be enrolled.TIP & nimotuzumab & triprilimab will be administered per 21-day until surgery, evidence of disease progression or onset of unacceptable toxicity.
