Cancer remains one of the leading causes of death worldwide. In India, approximately one in nine individuals receives a cancer diagnosis during their lifetime, making it a significant public health challenge. Cancer encompasses a collection of disorders that all begin when cells in the body grow uncontrollably, forming tumours that can spread to other parts of the body.

In 2023, an estimated 1.4 million people in India were living with cancer. The most frequently diagnosed cancers include breast cancer, oral cancer, cervical cancer, lung cancer, and colorectal cancer, among others. Treatment approaches vary significantly based on factors such as the patient's age, overall health, cancer stage, and tumour location.

Modern oncology in India adopts a multi-disciplinary approach, combining chemotherapy, surgery, radiation therapy, immunotherapy, and targeted therapy. Immunotherapy and targeted therapies have gained significant attention for their precision in targeting cancer cells, often leading to better patient outcomes. Personalised treatment plans prove crucial because every cancer and every patient presents unique characteristics. 

For patients and caregivers navigating treatment options, understanding the top anticancer medications available in India becomes essential.

This article provides an in-depth examination of the top 10 anti-cancer drugs available in the country and explains how they help combat these prevalent cancers.

What Is the Most Effective Treatment for Cancer?

Two key factors determine the success of cancer treatment: the stage of cancer at diagnosis and the type of therapy used. 

Oncologists adopt a multi-disciplinary approach to care, combining various treatment modalities. Of these options, immunotherapy and targeted therapies have gained significant attention for their precision in targeting cancer cells, often leading to better patient outcomes.

Personalised treatment plans prove crucial because every cancer and every patient differs. These tailored approaches account for the unique characteristics of both the cancer and the individual, ensuring treatment achieves maximum effectiveness.

What Are the Most Common Anticancer Drugs in India?

1. Pembrolizumab 

Pembrolizumab functions as a powerful immunotherapy drug that treats various types of cancer, including lung, colorectal, breast, ovarian, skin, stomach, and oesophageal cancers. It also proves effective against blood cancers and cancers of the head and neck. 

What makes pembrolizumab stand out is how it works with the body's immune system. It essentially boosts the body's natural defences, helping it recognise and attack cancer cells more effectively. The drug binds to specific receptors on immune cells and blocks certain proteins that encourage cancer cell growth, slowing or even halting disease progression.

Healthcare professionals administer pembrolizumab as an intravenous infusion. Recent studies show remarkable improvements in survival rates for patients, especially those with advanced-stage lung cancer, which has earned pembrolizumab the reputation of being a "blockbuster" cancer drug.

A few of the popular brands for this medicine include Keytruda and Pembrolizumab Biocon (Biocon version/biosimilar availability emerging). Whilst pembrolizumab provides a game-changing option for many patients, they should be aware that, like any treatment, it may produce side effects such as fatigue, skin rashes, or digestive issues. Always consult with your doctor to ensure it suits your condition.

2. Trastuzumab

In India, breast cancer ranks as the most common cancer amongst women, with one woman receiving a diagnosis every minute. Many cases are detected at later stages (3 and 4), underscoring the importance of targeted therapy to improve survival rates. One of the most aggressive forms, HER2-positive breast cancer, has become increasingly common.

Trastuzumab, a targeted therapy drug, treats HER2-positive breast cancer widely. This monoclonal antibody binds to HER2 receptors, which drive the rapid growth of cancer cells. By inhibiting these proteins, trastuzumab helps to slow down or stop cancer progression.

A few of the popular brands for this medicine include Hertraz. Healthcare professionals administer trastuzumab via intravenous infusion. It

can be used alone or in combination with chemotherapy and surgery. Its use has shown promising results, with many women experiencing improved outcomes. Beyond breast cancer, trastuzumab also proves effective in treating certain types of stomach and oesophageal cancers, making it a key player in targeted cancer therapies.

3. Bevacizumab 

Ovarian cancer ranks as the second most common cancer affecting women in India. Bevacizumab, a targeted therapy, works by blocking vascular endothelial growth factor (VEGF), a protein that promotes the formation of blood vessels within tumours, allowing them to grow and spread. By inhibiting VEGF, bevacizumab effectively slows cancer progression.

A few of the popular brands for this medicine include Avastin and Bevastas. Recent studies show that using bevacizumab as a first-line treatment for ovarian cancer yields positive results, especially in preventing recurrence. It also benefits patients with other cancers, such as lung, advanced brain, colon, breast, and cervical cancers that have metastasised. Oncologists often use bevacizumab in combination with chemotherapy to enhance its effectiveness in these aggressive cancers.

4. Nivolumab 

Nivolumab has shown remarkable success in treating advanced lung cancer in India, particularly for patients who haven't responded well to platinum-based chemotherapy. Recent studies highlight its effectiveness in managing recurrent lung cancer, making it a crucial option for many. A few of the popular brands for this medicine include Nivolumab.

This drug functions as an immunoglobulin 4 antibody, enhancing the immune system's ability to recognise and combat cancer cells. In addition to lung cancer, healthcare professionals use nivolumab for various other cancers, including colorectal, head and neck, gastric, blood, kidney, liver, skin, and bladder cancers. Notably, low doses of nivolumab have been associated with improved survival rates in patients with head and neck cancer, reinforcing its role as a vital treatment in oncology. 

5. Ipilimumab

Ipilimumab has shown promising results in treating metastatic colorectal cancer, which ranks among the top five cancers in India. As part of the immunotherapy class, this medication harnesses the immune system to target and eliminate cancer cells. Initially approved for treating aggressive skin cancer, ipilimumab has gained popularity for its effectiveness.

A popular medicine is Yervoy. Today, oncologists often use it in combination with nivolumab to treat liver, lung, and advanced kidney cancers, enhancing patient outcomes by attacking cancer from multiple angles. Recent studies indicate improved survival rates with this combination therapy, making it a valuable option in oncology.

6. Ramucirumab 

As stomach cancer cases continue to rise in India, particularly amongst men, ramucirumab has emerged as a significant option for treatment. This targeted therapy works by blocking the growth of blood vessels that supply tumours, effectively hindering the progression of gastric cancer.

A few of the popular brands are Cyramza and Ramucirumab. Healthcare professionals indicate ramucirumab specifically for advanced cases. Recent trials have shown that combining ramucirumab with traditional chemotherapy can improve efficacy and patient outcomes.

7. Atezolizumab 

Lung carcinoma ranks as the second most prevalent cancer in India, and atezolizumab makes waves for its ability to improve survival rates in patients. Studies indicate that about 24% of lung cancer patients treated with atezolizumab experience a two-year survival rate.

As a monoclonal antibody, it enhances the immune system's ability to combat cancer cells. Healthcare professionals can use atezolizumab post-surgery for non-small cell lung cancer or in combination with chemotherapy for extensive small cell lung cancer. Some of the popular brands include Tecentriq and Atezolizumab. Whilst effective, some patients may experience side effects, emphasising the need for careful monitoring during treatment.

8. Ribociclib 

Ribociclib has shown remarkable promise for younger women facing advanced metastatic breast cancer. Some of the popular brands include Kisqali and Ribociclib. Studies indicate that patients treated with ribociclib have a higher life expectancy compared to those receiving standard chemotherapy.

Long-term outcomes show that this targeted therapy can significantly prolong survival rates, making it a valuable option for those battling this aggressive form of cancer.

9. Sunitinib 

Renal cell carcinoma, one of the types of kidney cancer, affects around 85% of kidney cancer patients, with a higher incidence in Indian men. Sunitinib, a targeted therapy, has demonstrated a 60% disease-control rate in patients with advanced kidney cancer. Some of the popular brands available are Sutent and Sunitibenz.

Patients take this medication orally, and it also treats pancreatic cancer and stomach tumours. Sunitinib works by blocking enzymes that signal cancer cell growth, interrupting the pathways that fuel cancer progression. Managing side effects proves crucial for patients; common issues include fatigue and gastrointestinal discomfort, which healthcare providers can often address through supportive care strategies.

10. Ibrutinib 

Each year, approximately 100,000 individuals in India receive a blood cancer diagnosis, making it a growing health concern, especially amongst children. Ibrutinib, approved in 2016 as a first-line treatment for certain leukaemias, has shown significant success in extending patient survival by delaying cancer progression. Some of the popular brands available are Imbruvica and Ibrunat.

This targeted therapy works by inhibiting Bruton's protein kinase, a protein critical for the abnormal growth of cancer cells. Patients take it in pill form, and it has become a cornerstone in the treatment of blood cancers, with recent studies indicating promising outcomes for the Indian population.
