Penis cancer is a rare occurrence, but alarming predictions suggest a significant 77% increase in cases by the year 2050. While developing countries traditionally have higher rates of this type of cancer, there is a rising trend in most European countries as well. The ageing population in Europe is seen as a major contributor to the increase in cases, with individuals over the age of 50 being at a higher risk. Additionally, risk factors such as a narrowed foreskin, poor genital hygiene, and smoking tobacco have been identified as potential triggers for penis cancer. Interestingly, individuals who have been circumcised at birth are less likely to develop this type of cancer.
Role of Human Papillomaviruses (HPV) in Penis Cancer
Penis cancer is primarily attributed to squamous cells in the skin of the penis, accounting for over 90% of cases. Research has shown that infection with human papillomaviruses (HPV) is present in approximately half of the cases of squamous cell cancer. HPV is a highly contagious virus that spreads through skin contact, making it one of the most common sexually transmitted infections. Surprisingly, over 70% of sexually active adults contract HPV infections, often in adolescence, with most cases being asymptomatic and resolving over time. However, previous infection with HPV does not guarantee immunity against future infections, and some infections can persist beneath the skin surface, leading to pre-malignant changes in the skin texture and color.
Diagnosing penis cancer can pose challenges as many patients may experience guilt or embarrassment, delaying seeking medical help. Self-medication with antimicrobial or steroid creams is a common practice among men, further delaying professional medical assessment. Additionally, doctors may misclassify lesions as benign, contributing to diagnostic delays. Swift diagnosis is crucial as malignant cells spreading to the groin lymph glands significantly reduce the chances of a cure. Treatment options for penis cancer include surgical removal of cancerous tissues using laser or micro-surgery, with possible adjuvant therapies such as chemotherapy or radiotherapy. In severe cases where tumors do not respond to conventional treatments, amputation of the penis may be considered as a last resort.
Despite the challenges posed by penis cancer, new approaches offer hope for effective treatments. Engineered T cells, a type of immune cell that targets HPV-infected cells, have shown promise in treating some cases of penis cancer. Immunotherapies like tislelizumab have also demonstrated efficacy in improving immune responses to squamous cell tumors. Although the effects of HPV vaccines on reducing penis cancer rates may take time to manifest due to the delayed onset of cancer post-infection, ongoing research and advancements in treatment modalities provide optimism for better outcomes in managing penis cancer cases globally.
