Do I still need treatment after surgery for early stage testicular cancer? Early testicular cancer is generally well treated, but can early testicular cancer be cured after radical surgical resection? According to the guidelines and our experience, early testicular cancer still needs to be closely monitored and actively treated after radical surgery in order to achieve complete cure! We will briefly explain the treatment mode of early testicular cancer after surgery from the most common early stage (stage I) seminoma and non-seminomatous tumor! According to the latest testicular tumor staging criteria, about 15% to 20% of patients with stage I seminoma have retroperitoneal subclinical metastatic lesions, and the tumor may recur after radical orchiectomy. The median number of recurrences is about 12 months, and some recurrences occur more than 5 years after surgery. Treatment of stage seminoma. Therefore, patients can choose to be closely tested, adjuvant chemotherapy and adjuvant radiotherapy. 2. Treatment of stage I non-seminomatous cell tumor The selection of treatment plan after radical orchiectomy for patients with clinical stage I non-seminomatous cell tumor should follow the following principles: to avoid inadequate treatment leading to an increased recurrence rate, and to minimize toxic side effects due to overtreatment. For patients with clinical stage I non-seminomatous cell tumors, the cure rate can reach 99% as long as appropriate treatment measures are selected. The presence or absence of vascular and lymphatic infiltration is an important predictor. The risk of metastatic tumor in patients with vascular and lymphatic infiltration is 48%, while the risk of recurrence in patients without vascular and lymphatic infiltration is only 14%-22%. Patients may choose Close follow-up: advantages: avoid overtreatment; disadvantages: high recurrence rate, especially in high-risk patients (nearly 50%); adjuvant chemotherapy: advantages: low recurrence rate 2-3%; disadvantages: systemic toxicity, temporary effects on fertility, risk of secondary tumors; retroperitoneal lymph node dissection: advantages: high cure rate, no toxicity of chemotherapy; disadvantages: surgical risk, 2-10% retrograde ejaculation.
