Anal cancer is a rare but increasingly prevalent cancer that originates in the tissues of the anus—the final part of the digestive tract. 

Globally, it accounts for approximately 50,000 new cases each year, with incidence rates steadily rising, mainly in high-income countries. According to the World Health Organization (WHO), the majority of anal cancer cases are linked to human papillomavirus (HPV) infection, especially HPV-16, which is detected in over 90% of cases. Although it represents less than 1.5% of all gastrointestinal cancers worldwide, the disease poses significant challenges due to its location and potential impact on quality of life.

Understanding treatment options is essential—especially the role of surgery in achieving a cure. In this blog, we explore whether surgery can completely cure anal cancer and when it offers the most benefit.

What is Anus?

The anus is the opening at the end of the digestive tract, responsible for expelling feces from the body. Comprising muscles and tissues, it controls bowel movements. It’s the endpoint where waste material exits the rectum, aiding in waste elimination and maintaining bowel function.

What is Anal Cancer?

Anal cancer develops in the cells of the anus, which is responsible for controlling bowel movements. It can occur in various forms, but the most common type is squamous cell carcinoma, which originates in the squamous cells lining the anus. 

Symptoms of Anal Cancer:

• Rectal bleeding or discharge
• Pain, itching, or discomfort in the anal area
• Changes in bowel habits
• Swollen lymph nodes in the groin
• Visible lumps or growths around the anus
• Fatigue and unexplained weight loss
• Anorectal pain during bowel movements

Risk Factors for Anal Cancer:

• Infection with high-risk strains of HPV
• Weakened immune system (e.g., HIV/AIDS)
• History of anal dysplasia
• Smoking
• Multiple sexual partners
• Age (higher risk in older individuals)
• History of cervical, vaginal, or vulvar cancer

Is Surgery a Viable Treatment Option?

Surgery is a pivotal component in the comprehensive treatment strategy for anal cancer. Its primary objective is the removal of cancerous cells, whether partially or entirely, to enhance the chances of a cure. 

The selection of a specific surgical approach depends on various factors, including the stage and extent of the disease. Below, we elaborate on the surgical techniques commonly employed in the management of anal cancer:

• Local Excision: This technique is typically reserved for early-stage anal cancer cases where the tumor is small and confined to a specific area. During a local excision, surgeons remove the cancerous growth and a margin of surrounding healthy tissue to ensure that no malignant cells remain.
• Abdominoperineal Resection (APR): More advanced anal cancer cases often necessitate an APR, particularly when the disease has progressed or spread. The APR procedure involves the extensive removal of the anus, rectum, and nearby lymph nodes, aiming to eliminate the cancer and reduce the risk of recurrence.
• Chemoradiation Therapy: In some situations, especially when the tumor is large or aggressive, a combined approach involving chemotherapy and radiation therapy may precede surgery. This approach helps shrink the tumor, making it more manageable for surgical removal.

However, the effectiveness of surgery in treating anal cancer is influenced by various factors, including the stage at which the cancer is diagnosed. Additionally, the patient’s overall health plays a significant role in determining the success of surgical intervention. 

Individuals diagnosed with anal cancer need to consult with a healthcare team, including surgeons and oncologists, to determine the most appropriate treatment plan tailored to their specific condition. Surgery, when combined with other therapies, can significantly improve outcomes and increase the likelihood of a successful recovery from anal cancer.

“When I was diagnosed with early-stage anal cancer, I was terrified. But Dr. Goel’s team explained everything so clearly. I underwent a local excision, and within a few weeks, I was recovering well. It’s been a year now, and I’m cancer-free. I owe my life to their prompt action and surgical expertise,” says one patient of Dr. Deep Goel.

Another patient of Dr. Deep shared, “My cancer was advanced, and I needed an abdominoperineal resection. It wasn’t an easy journey, especially adjusting to life with a colostomy. But with support from my care team and family, I’ve adapted. More importantly, I’m alive and doing well. Dr. Goel didn’t just treat my cancer—he gave me a second chance.”

What is the Effectiveness of Surgery?

The effectiveness of surgery as a treatment for anal cancer is a topic of significant importance. Surgery can be a valuable component of the treatment plan, particularly in some instances. It is most effective when the cancer is diagnosed early and localised, meaning it hasn’t spread to nearby lymph nodes or distant organs.

For small anal tumors, surgical removal can be curative, providing an excellent chance of complete recovery. The type of surgical procedure employed, such as wide local excision or abdominoperineal resection, depends on the tumor’s size and location.

In more advanced cases where the cancer has spread, surgery may be used in conjunction with other treatments like radiation and chemotherapy. The goal shifts from curative to palliative, focusing on symptom relief and improving the patient’s quality of life.

Dr. Deep Goel says, “The effectiveness of surgery in treating anal cancer is closely intertwined with early diagnosis. When applied at the right moment, surgical intervention can be incredibly potent. It is particularly beneficial in localised cases, where the tumor hasn’t extended to nearby lymph nodes or distant organs.” 

He further highlights, “For small anal tumors, surgical removal holds the promise of a complete cure, offering patients an excellent chance of returning to a cancer-free life. However, in advanced stages, when the cancer has spread, a multidisciplinary approach, incorporating surgery alongside radiation and chemotherapy, aims at symptom relief and enhancing the patient’s overall quality of life.” 

What are the Challenges and Considerations?

While surgery remains a critical component of anal cancer treatment, several challenges and considerations need to be acknowledged:

1. Early Detection: It is the key to a successful cure. Regular screenings and awareness of potential symptoms are essential for timely diagnosis.
2. Multimodal Approach: In many cases, surgery is combined with other treatment modalities, such as chemotherapy and radiation therapy, to enhance effectiveness.
3. Personalised Treatment: Each case of anal cancer is unique, and treatment plans must be tailored to the patient’s specific circumstances.
4. Quality of Life: Surgical procedures like APR can significantly impact a patient’s quality of life, given the changes in bowel habits and the need for colostomy bags.

What Is the Cost of Anal Cancer Treatment in India?

The cost of treating anal cancer in India is significantly lower compared to many Western countries, making it a preferred destination for international patients seeking quality and affordable care. The cost in India ranges from ₹4,00,000 – ₹10,00,000 (USD 4,800 – USD 12,000), depending on complexity and hospital.

However, the overall cost varies depending on the stage of cancer, the type of treatment recommended (surgery, chemoradiation, or both), hospital location, doctor expertise, and duration of hospital stay. 

Conclusion

Surgery plays a vital role in the management of anal cancer, especially when the disease is detected at an early stage. With advancements in surgical techniques and the integration of multimodal therapies, the chances of achieving a complete cure have significantly improved. However, the choice of surgical approach and its success largely depend on factors like the tumor’s size, location, stage, and the patient’s overall health.

Ultimately, staying informed, seeking timely medical advice, and choosing an experienced care team are the most critical steps toward overcoming anal cancer. With the right support, many patients not only survive but thrive after treatment, reclaiming their health and peace of mind.
