Treatment Options for Penile Cancer – Surgery, Radiation, Chemotherapy, and Emerging Therapies
Overview of Penile Cancer Treatment
Penile cancer is a relatively rare form of cancer that affects the penis. It typically starts in the cells of the skin or glands of the penis and can manifest as a lump or sore on the penis. Treatment options for penile cancer depend on the stage of the cancer, the overall health of the patient, and other individual factors.
Surgery for Penile Cancer
Surgical treatment is often the primary approach for penile cancer. The extent of surgery may vary depending on the size and location of the tumor. Types of surgical procedures for penile cancer include:
- Partial penectomy: Removal of a portion of the penis.
- Total penectomy: Removal of the entire penis.
- Penile-preserving surgery: Aims to remove the cancer while preserving the function and appearance of the penis.
Surgical options for penile cancer also involve lymph node dissection to assess the spread of cancer, especially in advanced cases. Adjuvant therapy, such as radiation or chemotherapy, may be recommended after surgery to reduce the risk of cancer recurrence.
Radiation Therapy for Penile Cancer Treatment
Radiation therapy uses high-energy rays to target and destroy cancer cells. It may be used as the primary treatment for penile cancer in cases where surgery is not feasible or as adjuvant therapy after surgery to eliminate any remaining cancer cells. Radiation therapy for penile cancer may be delivered externally or internally (brachytherapy).
A study published in the Journal of Urology found that radiation therapy was effective in reducing tumor size and improving survival rates in patients with advanced penile cancer. The study reported a 5-year overall survival rate of 59% for patients treated with radiation therapy.
Common side effects of radiation therapy for penile cancer include skin irritation, fatigue, and urinary symptoms. Patients undergoing radiation therapy require close monitoring and supportive care to manage these side effects effectively.
Surgical Options for Penile Cancer
Penile cancer treatment often involves surgical options, depending on the stage and extent of the disease. Surgery is typically the primary treatment for localized penile cancer and may also be used in advanced cases to remove tumors and affected tissue.
Types of Surgical Procedures
There are several surgical options available for the treatment of penile cancer:
- Partial Penectomy: In cases where the cancer is limited to a specific area of the penis, a partial penectomy may be performed to remove only the affected part of the organ while preserving sexual function as much as possible.
- Total Penectomy: This procedure involves the complete removal of the penis, often necessary in advanced cases where the cancer has spread extensively.
- Regional Lymph Node Dissection: Lymph nodes in the groin area may also be removed to prevent the spread of cancer cells to other parts of the body.
Reconstructive Surgery
Following extensive penile surgery, reconstructive procedures may be considered to restore appearance and function. This can involve techniques such as skin grafting, phalloplasty (reconstruction of the penis), or the use of prosthetic implants.
Post-Surgery Care
After surgical intervention for penile cancer, patients may require specialized care to manage wound healing, prevent complications, and ensure optimal recovery. Close monitoring and follow-up visits with healthcare providers are essential to address any post-operative issues and monitor for signs of recurrence.
Studies and Statistics
According to the American Cancer Society, surgical treatment for localized penile cancer has a high success rate, especially when combined with adjuvant therapies such as radiation or chemotherapy. Research studies continue to explore the effectiveness of different surgical approaches and combination treatments to improve outcomes and quality of life for patients with penile cancer.

Radiation Therapy for Penile Cancer Treatment
Radiation therapy is a common treatment option for penile cancer, especially for patients who are not surgical candidates or who have locally advanced disease. This type of therapy uses high-energy beams to target and destroy cancer cells in the affected area. Radiation therapy can be delivered externally or internally, depending on the specific situation and stage of the cancer.
Types of Radiation Therapy
There are two main types of radiation therapy used for penile cancer treatment:
- External Beam Radiation Therapy (EBRT): This involves directing radiation from a machine outside the body towards the tumor. EBRT is typically given daily over several weeks.
- Brachytherapy: In this form of radiation therapy, radioactive sources are placed directly into or near the tumor. This allows for a higher dose of radiation to be delivered to the cancer while minimizing exposure to surrounding healthy tissue.
Effectiveness of Radiation Therapy
Radiation therapy can be an effective treatment for penile cancer, especially when used in combination with surgery or other therapies. According to the American Cancer Society, the 5-year survival rate for localized penile cancer treated with radiation therapy is around 70%. However, the effectiveness of radiation therapy may vary depending on the stage of the cancer and other factors.
Side Effects of Radiation Therapy
While radiation therapy can be an important part of penile cancer treatment, it can also cause side effects. Common side effects of radiation therapy for penile cancer may include:
- Skin irritation or changes in the treated area
- Fatigue
- Erectile dysfunction
- Bladder or bowel problems
It’s important for patients to discuss potential side effects with their healthcare team and to follow their recommendations for managing them.

Chemotherapy and Systemic Therapy for Penile Cancer
Chemotherapy is a common treatment option for penile cancer that involves the use of drugs to kill cancer cells. It is often used in combination with other treatment modalities such as surgery or radiation therapy. Systemic therapy refers to treatments that are delivered throughout the body to target cancer cells that may have spread beyond the primary tumor site.
Chemotherapy: Chemotherapy drugs for penile cancer may include cisplatin, 5-fluorouracil (5-FU), paclitaxel, and docetaxel. These drugs can be given orally or intravenously and work by targeting rapidly dividing cancer cells. Chemotherapy is typically administered in cycles with breaks in between to allow the body to recover from side effects.
Systemic Therapy: In addition to chemotherapy, systemic therapies for penile cancer may include targeted therapy and immunotherapy. Targeted therapy drugs such as cetuximab and pembrolizumab can specifically target cancer cells while sparing healthy cells, leading to fewer side effects.
Immunotherapy: Immunotherapy aims to stimulate the body’s immune system to recognize and attack cancer cells. Checkpoint inhibitors, such as pembrolizumab and nivolumab, have shown promising results in treating advanced penile cancer by blocking proteins that prevent immune cells from attacking cancer cells.
Combination Therapy: Combining chemotherapy with targeted therapy or immunotherapy has shown potential benefits in treating penile cancer. Studies have demonstrated improved outcomes and increased response rates with combination therapies compared to single-agent treatment approaches.
According to the American Cancer Society, the use of combination chemotherapy regimens has been associated with higher response rates and better overall survival in patients with advanced penile cancer. Clinical trials are also investigating novel drug combinations to further enhance treatment efficacy and reduce side effects.
| Chemotherapy Drug | Mode of Administration |
|---|---|
| Cisplatin | Intravenous |
| 5-Fluorouracil (5-FU) | Intravenous |
| Paclitaxel | Intravenous |
| Docetaxel | Intravenous |
In a study published in the British Journal of Cancer, researchers found that combination chemotherapy with cisplatin and 5-FU showed a response rate of 46% in patients with metastatic or locally advanced penile cancer. The study highlighted the importance of tailored treatment regimens based on individual patient characteristics.
It is essential for patients with penile cancer to discuss treatment options with their healthcare providers, including the potential benefits and side effects of chemotherapy, targeted therapy, and immunotherapy.
