tip (paclitaxel + ifosfamide + cisplatin) combined with nimotuzumab & triprilimab as neoadjuvant treatment in locally advanced penile cancer

Conditions: Penile Cancer

Summary: primary objective:to evaluate the efficacy and safety of tip (paclitaxel + ifosfamide + cisplatin) combined with nimotuzumab \& triprilimab as neoadjuvant treatment in locally advanced penile cancer.

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.
