Penile cancer is a malignant growth found on the skin or in the tissues of the penis, usually originating in the glans and/or foreskin. It is a rare form of cancer with an annual incidence of 1 in 100,000 in developed countries.[1] The following codes are used with International Statistical Classification of Diseases and Related Health Problems. ... // C00-D48 - Neoplasms (C00-C14) Malignant neoplasms, lip, oral cavity and pharynx (C00) Malignant neoplasm of lip (C01) Malignant neoplasm of base of tongue (C02) Malignant neoplasm of other and unspecified parts of tongue (C03) Malignant neoplasm of gum (C04) Malignant neoplasm of floor of mouth (C05) Malignant neoplasm of...

Risk Factors

The American Cancer Society provides the following as risk factors for penile cancer: human papillomavirus (HPV) infection, smoking, smegma, phimosis, lack of circumcision, treatment of psoriasis, age, and AIDS. Human papillomavirus (HPV) is a member of a group of viruses known as the genus Papillomavirus that can infect humans and cause changes in cells leading to abnormal tissue growth. ... Phimosis is a medical condition in which the foreskin of the penis of an uncircumcised male cannot be fully retracted. ... Circumcision is the removal of some or all of the foreskin (prepuce) from the penis. ... Acquired immunodeficiency syndrome, or acquired immune deficiency syndrome (or acronym AIDS or Aids), is a collection of symptoms and infections resulting from the specific damage to the immune system caused by infection with the human immunodeficiency virus (HIV). ...


There is some evidence that lichen sclerosus (also known as balanitis xerotica obliterans) may also be a risk factor.[2] Discussion Balanitis xerotica obliterans (BXO) is a skin disease of unknown origin. ...


Risk

While treatment is often easy, the overall 5-year survival rate for all stages of penile cancer is about 50%. Specifically in the United States the lifetime risk of an uncircumcised man for developing invasive penile cancer (IPC) is one in 600 [3], which is in excess of 3 times higher than for males neonatally circumcised.[4][5][6]


The evidence indicates that childhood circumcision reduces the incidence of penile cancer. [7][8][9][10][11][12] Circumcision is the removal of some or all of the foreskin (prepuce) from the penis. ...


The American Cancer Society noted in a 1998 statement: The American Cancer Society is a charitable organization dedicated to eliminating cancer. ...

"... penile cancer risk is low in some uncircumcised populations, and circumcision is strongly associated with other socioethnic practices that are associated with lessened risk. The consensus among studies that have taken these other factors into account is that circumcision alone is not the major factor preventing cancer of the penis. It is important that the issue of circumcision not distract the public's attention from avoiding known penile cancer risk factors -- having unprotected sexual relations with multiple partners (increasing the likelihood of human papillomavirus infection) and cigarette smoking."[13]

Studies have found that circumcision decreases the risk of HPV infection in males and thereby the risk of developing penile cancer.[14][15][16]


Wallerstein found that the risk of penile cancer in Finland, Norway, and Denmark (all noncircumcising countries) is about the same (1 in 100,000 per year) as in the U.S.


The American Medical Association and the Royal Australasian College of Physicians say the use of infant circumcision in hope of preventing penile cancer in adulthood is not justified. [17] [18]


Signs and Symptoms

A draining sore on the foreskin or glans of the penis may be a sign of penile cancer and anyone with these symptoms should consult a doctor immediately.


Staging

Like many malignancies, penile cancer can spread to other parts of the body. It is usually a primary malignancy, the initial place from which a cancer spreads in the body. Much less often is it a secondary malignancy, where cancer has spread to the organ from other antatomy. Doctors use the extent of metastasis to complete a process called staging. Patients will be assigned a "stage" to aid in treatment decisions and prognosis.



Stage I

  • Cancer has only affected the glans and/or foreskin.

Stage II
The penis (plural penises or penes) or phallus is an external male sexual organ. ...

  • Cancer has spread to the shaft of the penis.

Stage III
The penis (plural penises or penes) or phallus is an external male sexual organ. ...

  • Cancer has affected the penis and surrounding lymph nodes.

Stage IV
Lymph nodes are components of the lymphatic system. ...

  • Cancer has moved beyond the groin area to other parts of the body.

Recurrent

  • Cancer that has returned after treatment.

Prognosis can range considerably for patients, depending where on the scale they have been staged. Generally speaking, the earlier the cancer is diagnosed, the better the prognosis. The overall 5-year survival rate for all stages of penile cancer is about 50%.


Treatment

There are several treatment options for penile cancer, depending on staging. They include surgery, radiation therapy, chemotherapy, and biological therapy. The most common treatment is one of four types of surgery: A typical modern surgical operation Surgery (from the Greek cheirourgia meaning hand work) is the medical specialty that treats diseases or injuries by operative manual and instrumental treatment. ... Clinac 2100 C accelerator Radiation therapy (or radiotherapy) is the medical use of ionising radiation as part of cancer treatment to control malignant cells (not to be confused with radiology, the use of radiation in medical imaging and diagnosis). ... Chemotherapy is the use of chemical substances to treat disease. ... Immunotherapy is a disease treatment based upon the concept of triggering the bodys own natural defenses to fight off the disease, usually by stimulating the immune system either locally or systemically. ...



Wide Local Excision

  • The tumor and some surrounding healthy tissue are removed.

Microsurgery

  • Surgery performed with a microscope is used to remove the tumor and as little healthy tissue as possible.

Laser Surgery

  • Laser light is used to burn or excise cancerous cells.

Circumcision

  • Cancerous foreskin is removed from the penis.

Amputation

  • The most common and effective treatment of penile cancer is penectomy. A penectomy can range from partial to total removal of the penis. The surgeon may also decide to remove associated lymph nodes.

Radiation therapy is usually used adjuvantly with surgery to reduce the risk of recurrence. With earlier stages of penile cancer, a combination of topical chemotherapy and less invasive surgery may be used. More advanced stages of penile cancer usually require a combination of surgery, radiation and chemotherapy.


Vaccine

A bi-valent vaccine to prevent HPV infection has been developed and successfully tested.[19] This vaccine, when it is licenced and goes into production, could substantially reduce the incidence of HPV infection, the incidence of ano-genital cancers, including penile cancer, and reduce mortality.[20]

Cancer cells are found only on the surface of the glans (the head of the penis) and on the foreskin (the loose skin that covers the head of the penis).
Stage II Cancer cells are found in the deeper tissues of the glans and have spread to the shaft of the penis (the long, slender cylinders of tissue inside the penis that contain spongy tissue and expand to produce erections).
