What are The Latest Treatment Methods in Cancer in India?
Introduction
Cancer, a formidable adversary in the realm of health, continues to be a major cause of concern globally.
In India, where the cancer burden is significant, the evolution of treatment methods is crucial in enhancing survival rates and improving quality of life.
Over the past few years, India has seen remarkable advancements in cancer treatment, ranging from precision medicine to cutting-edge surgical techniques.
This article delves into the latest cancer treatment methods in India, providing a comprehensive overview of the progress made and the options available to patients.
Understanding Cancer Treatment in India
Cancer treatment in India has traditionally included surgery, chemotherapy, and radiation therapy.
While these methods remain foundational, the landscape of oncology has expanded with the introduction of new techniques and technologies.
Indian oncologists now leverage a combination of traditional and modern treatments, tailoring approaches to the specific needs of each patient.
This personalised approach has been made possible through advancements in diagnostic tools, molecular biology, and a deeper understanding of cancer's behaviour.
1. Precision Medicine: Tailoring Treatment to the Individual
One of the most significant advancements in cancer treatment in India is the adoption of precision medicine.
Precision medicine involves analysing the genetic makeup of a patient's tumour to identify specific mutations and markers that can be targeted with tailored therapies.
This method ensures that treatment is highly specific, reducing the likelihood of side effects and improving efficacy.
In India, leading cancer centres such as Tata Memorial Hospital in Mumbai and AIIMS in New Delhi have begun integrating precision medicine into their treatment protocols.
By using next-generation sequencing (NGS) and other advanced genomic tools, oncologists can develop personalised treatment plans that offer better outcomes.
2. Immunotherapy: Harnessing the Body's Immune System
Immunotherapy represents a groundbreaking approach to cancer treatment by enhancing the body's natural defences to fight cancer cells.
This method has gained traction in India, particularly for treating cancers such as melanoma, lung cancer, and certain types of lymphoma.
The most common types of immunotherapy in India include:
Checkpoint Inhibitors:
These drugs, such as pembrolizumab and nivolumab, block proteins that prevent the immune system from attacking cancer cells.
By inhibiting these checkpoints, the immune system can recognize and destroy cancer more effectively.
CAR T-Cell Therapy:
This innovative treatment involves modifying a patient’s T-cells to target and kill cancer cells.
Although still in its early stages in India, CAR T-cell therapy has shown promising results, particularly in treating blood cancers like leukaemia and lymphoma.
Cancer Vaccines:
Unlike traditional vaccines, cancer vaccines are designed to stimulate the immune system to target cancer cells.
India is actively involved in research and development in this area, with ongoing clinical trials exploring the efficacy of various cancer vaccines.
3. Targeted Therapy: Attacking Cancer at Its Core
Targeted therapy is another advancement in cancer treatment, focusing on specific molecules involved in cancer growth and progression.
Unlike chemotherapy, which affects all rapidly dividing cells, targeted therapy is more precise, minimising damage to healthy cells.
In India, targeted therapy is commonly used to treat cancers such as breast cancer, lung cancer, and colorectal cancer.
The availability of drugs like trastuzumab for HER2-positive breast cancer and tyrosine kinase inhibitors (TKIs) for chronic myeloid leukaemia (CML) has significantly improved patient outcomes.
The development of biosimilars, which are biologic medical products highly similar to already approved reference products, has also made targeted therapy more accessible in India.
This has reduced treatment costs, making these therapies available to a broader population.
4. Proton Therapy: A New Frontier in Radiation Treatment
Proton therapy is an advanced form of radiation therapy that uses protons rather than X-rays to treat cancer.
The advantage of proton therapy is its precision – it delivers high doses of radiation directly to the tumour with minimal impact on surrounding healthy tissues.
This is particularly beneficial for treating cancers located near critical structures, such as brain tumours, head and neck cancers, and paediatric cancers.
In India, proton therapy is available at select centres, such as the Apollo Proton Cancer Centre in Chennai.
This facility, the first of its kind in South Asia, offers state-of-the-art proton therapy and has treated thousands of patients since its inception.
As awareness and demand for this technology grows, more centres across India are expected to adopt proton therapy.
5. Robotic Surgery: Enhancing Precision in Surgical Oncology
Robotic surgery has revolutionised the field of surgical oncology by allowing surgeons to perform complex procedures with greater precision, flexibility, and control.
The use of robotic systems, such as the Da Vinci Surgical System, enables minimally invasive surgeries, leading to shorter recovery times, less pain, and reduced risk of complications.
In India, robotic surgery is increasingly being used to treat cancers of the prostate, cervix, colon, and rectum.
Hospitals like Fortis Memorial Research Institute, Gurgaon, and Kokilaben Dhirubhai Ambani Hospital, Mumbai, are at the forefront of adopting robotic surgery techniques.
As the technology becomes more widespread, it is expected that robotic surgery will become a standard option for many cancer patients in India.
6. Liquid Biopsy: A Non-Invasive Diagnostic Tool
Liquid biopsy is an emerging technique that offers a non-invasive alternative to traditional tissue biopsies.
By analysing a blood sample, liquid biopsy can detect genetic mutations, monitor disease progression, and evaluate treatment response.
This method is particularly useful for detecting cancer at an early stage and for patients with tumours that are difficult to biopsy.
In India, liquid biopsy is gaining popularity as a diagnostic tool, especially for cancers like lung cancer, where traditional biopsies can be challenging.
Companies such as Strand Life Sciences and MedGenome are leading the way in providing liquid biopsy services, making it more accessible to patients across the country.
7. Advanced Chemotherapy Techniques
While chemotherapy remains a cornerstone of cancer treatment, advances in the delivery and formulation of chemotherapy drugs have improved their effectiveness and reduced side effects. Some of the latest techniques in India include:
Metronomic Chemotherapy:
This approach involves administering low doses of chemotherapy drugs at regular intervals, rather than in high doses at longer intervals.
Metronomic chemotherapy is less toxic and can be used for long-term management of certain cancers.
Hyperthermic Intraperitoneal Chemotherapy (HIPEC):
HIPEC is used to treat cancers that have spread to the abdominal cavity, such as ovarian or colorectal cancer.
After surgically removing visible tumours, heated chemotherapy drugs are circulated in the abdomen to kill remaining cancer cells.
This technique is available at several leading cancer centres in India, including Tata Memorial Hospital and AIIMS.
Nano-Chemotherapy:
The use of nanotechnology in chemotherapy involves delivering drugs directly to cancer cells, minimising damage to healthy cells.
Research in this area is ongoing in India, with promising results from early clinical trials.
8. Integrative Oncology: Combining Conventional and Alternative Treatments
Integrative oncology combines conventional cancer treatments with complementary therapies such as Ayurveda, yoga, acupuncture, and dietary counselling.
This approach is gaining acceptance in India as a way to enhance overall well-being, manage side effects, and improve the quality of life for cancer patients.
Several cancer centres in India, including the Cancer Institute (WIA) in Chennai and the Dharamshila Narayana Superspeciality Hospital in Delhi, offer integrative oncology programs.
These programs are designed to support patients throughout their cancer journey, addressing physical, emotional, and spiritual needs.
9. Stem Cell Therapy: A Promising Frontier
Stem cell therapy is an emerging area of cancer treatment that involves replacing damaged or destroyed bone marrow with healthy stem cells.
This treatment is particularly effective for blood cancers like leukaemia, lymphoma, and multiple myeloma.
India has made significant strides in stem cell therapy, with several hospitals offering both autologous (using the patient’s own cells) and allogeneic (using donor cells) transplants.
The availability of stem cell registries and advances in HLA typing have improved the success rates of these procedures in India.
10. Clinical Trials and Research: Pioneering New Treatments
India is playing an increasingly important role in global cancer research, with numerous clinical trials being conducted across the country.
These trials provide patients with access to the latest treatments and contribute to the development of new therapies.
Institutions like the Indian Council of Medical Research (ICMR) and private organisations such as Biocon and Dr. Reddy’s Laboratories are actively involved in cancer research.
Patients participating in clinical trials benefit from cutting-edge treatments and contribute to the advancement of medical science.
Challenges and the Way Forward
Despite the significant advancements in cancer treatment, India faces several challenges in ensuring that these treatments are accessible to all patients. Key challenges include:
Cost of Treatment:
Advanced cancer treatments such as proton therapy and CAR T-cell therapy are expensive, making them unaffordable for many patients.
While the introduction of biosimilars and generic drugs has helped reduce costs, more efforts are needed to make cutting-edge treatments accessible to a larger population.
Awareness and Early Detection:
Early detection is crucial for improving cancer survival rates, yet many patients in India are diagnosed at advanced stages.
Increased public awareness, regular screening programs, and improved diagnostic facilities are essential to address this issue.
Healthcare Infrastructure:
While major cities in India have world-class cancer treatment centres, access to advanced care remains limited in rural and remote areas.
Strengthening healthcare infrastructure and training healthcare professionals in these regions is vital to ensure equitable access to cancer care.
Palliative Care:
Integrating palliative care into the overall cancer treatment plan is essential for improving the quality of life for patients with advanced cancer.
More resources and training are needed to provide comprehensive palliative care services across India.
