'''Penile cancer''' is a [[cancer|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 incidence of 1 in 100,000 per year in developed countries.[http://www.cancer.org/docroot/CRI/content/CRI_2_4_1X_What_are_the_key_statistics_for_penile_cancer_35.asp?sitearea=]
 
==Risk factors==
The [[American Cancer Society]] [http://www.cancer.org/docroot/CRI/content/CRI_2_4_2X_What_are_the_risk_factors_for_penile_cancer_35.asp?sitearea= provides] the following as risk factors for penile cancer: [[human papillomavirus]] (HPV) infection, [[tobacco smoking|smoking]], [[smegma]], [[phimosis]], treatment of [[psoriasis]], age, and [[AIDS]]. The other etiologic factor most commonly associated with penile carcinoma is poor hygiene.  There is some evidence that lichen sclerosus (also known as [[balanitis xerotica obliterans]]) may also be a risk factor.[http://bmj.bmjjournals.com/cgi/eletters/321/7264/792#110919]
 
==Risk==
 
The lifetime risk of a man developing invasive penile cancer (IPC) in the United States is 1 in 600 if he is uncircumcised  [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=7377156&dopt=Abstract], and more than 3 times lower if he was circumcised neonatally.[http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11144896&dopt=Abstract][http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=8380060&dopt=Abstract][http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=8260177&dopt=Abstract]
 
This and other evidence suggests that childhood [[circumcision]] reduces the incidence of penile cancer.[http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11196386&dopt=Abstract][http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11144896&dopt=Abstract][http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=7377156&dopt=Abstract][http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11405332&dopt=Abstract][http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=10643514&dopt=Abstract][http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=10699138&dopt=Abstract] Studies have found that circumcision decreases the risk of HPV infection in males and thereby the risk of developing penile cancer.[http://content.nejm.org/cgi/pmidlookup?view=short&pmid=11948269][http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=15388997][http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=12238658] 
 
But 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 US.  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.[http://www.ama-assn.org/ama/pub/category/13585.html][http://www.racp.edu.au/hpu/paed/circumcision/print.htm] The [[American Cancer Society]] stated in 1998:
: "... 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."[http://www.cancer.org/docroot/CRI/content/CRI_2_4_2X_What_are_the_risk_factors_for_penile_cancer_35.asp?sitearea=]

A draining [[sore]] on the foreskin or glans of the penis may be a sign of penile cancer. Anyone with these symptoms should consult a doctor immediately.
==[[Carcinoma of the penis overview|Overview]]==


== Pathology ==
==[[Carcinoma of the penis classification|Classification]]==
* A. Precancerous Dermatologic Lesions
* B. Carcinoma in Situ (Bowen Disease, Erythroplasia of Queyrat)
* C. Invasive Carcinoma of the Penis


==Staging==
==[[Carcinoma of the penis historical perspective|Historical Perspective]]==


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 it is a secondary malignancy, one in which the cancer has spread to the penis from elsewhere. Doctors use the extent of [[metastasis]] to estimate what stage the disease is in, to aid in treatment decisions and prognosis. The stages are assessed as follows:
==[[Carcinoma of the penis pathophysiology|Pathophysiology]]==


* Stage I - Cancer has only affected the [[penis|glans]] and/or foreskin.
==[[Carcinoma of the penis epidemiology and demographics|Epidemiology & Demographics]]==
* Stage II - Cancer has spread to the [[penis|shaft]] of the penis.
* Stage III - Cancer has affected the penis and surrounding [[lymph nodes]].
* Stage IV - 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%.
==[[Carcinoma of the penis risk factors|Risk Factors]]==


== Treatment ==
==[[Carcinoma of the penis screening|Screening]]==


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:
==[[Carcinoma of the penis causes|Causes]]==


* [[Wide local excision]] - The tumor and some surrounding healthy tissue are removed
==[[Carcinoma of the penis differential diagnosis|Differentiating Carcinoma of the penis from other Diseases]]==
* 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 cut away cancerous cells
* Circumcision - cancerous foreskin is removed
* Amputation ([[penectomy]]) - a partial or total removal of the penis, and possibly the associated [[lymph nodes]].  This is the most common and effective treatment.


[[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.
==[[Carcinoma of the penis natural history|Natural History, Complications & Prognosis]]==


== Vaccine ==
==Diagnosis==
A quadri-valent vaccine to prevent HPV infection, [[Gardasil]], has been developed, successfully tested and approved for women by the US [[Food and Drug Administration]].[http://www.nature.com/nrd/journal/v5/n8/full/nrd2117.html] Approval for men is expected in 2008. It is licensed and in production, and could substantially reduce the incidence of HPV infection in men, the incidence of genital warts and ano-genital cancers including penile cancer, and mortality.[http://www.cirp.org/library/disease/cancer/lehtinen1/] It is unclear why the drug's manufacturer chose to stagger testing of the vaccine, potentially leaving many men needlessly vulnerable to HPV infection.
