Cancer: Integrative oncology A Holistic Outlook

The world has seen significant improvements in the quality of cancer care over the last decade.Though, it still remains one of the most dreaded ailments. Prevalence of cancer in India is estimated to be 3.9 million people with reported incidence of 1.1 million in 2015. India’s age-standardized cancer incidence estimated at 150-200 per 1,00,000 population. It is higher than Africa and on par with China. Breast and Cervical cancers are more found among Women however Head & Neck, Lung and GIT cancers among Men.

According to the Pharmacology, a branch of medical science which study how drugs exert their effects on living systems on following principle, “What Drug acts to the body &WhatBody acts to Drug”. It can also modifyas “What Food, Water & Air acts to the body & What Body acts to Food, Water & Air”. The balance between these 3- elements keeps us healthy however, imbalance give rise to Free Radicals or Reactive Oxygen Species (ROS) these cause damage to DNA, Proteins & Lipids, pathogenesis of Cancer, Diabetes mellitus, Degenerative, Rheumatoid, Heart Diseases, Ageing and many more.

There are many things which are responsible to cause generation of such free radicals. We had a predominantly Plant based diet and with the advent of western life style we are moving towards a diet rich in Animal proteins. This coupled with other habits like Smoking & Alcohol. Avoidance of tobacco and alcohol is the most important preventive action against Mouth, Throat and Lung cancers. Tobacco alone is responsible for about 40 - 50% of cancers in Men & about 20% of cancers in Women.

In India the availability and affordability of cancer treatment shows wide disparities. The majority of patients come in late stages of the disease (80% are advanced) and this adds to the already high morbidity, mortality & expenditure. The most common and available curative treatment involves, surgery, radiation, chemotherapy, hormone therapy or some combination of these modalities.

Some of the major side effects of current cancer therapy are Fatigue, Hair Loss, Neuropathy, Pain, Effects on Sexual Organs and Sexuality, Sleep Problems, Nausea & Vomiting, Anemia, Kidney and Bladder Effects, Diarrhea and Constipation, Memory or Concentration Problems. Above all, the mental agony apart from these side effects cannot be measured which makes the patient drop the treatment voluntarily.

The prime goal of current treatment approach is to decrease Anxiety, Fear, Depression and Pain. The ideal treatment approach should be designed to promote a sense of Emotional, Physical, Spiritual well-being. Developing country like India which has traditional medical heritage has multiple native traditional practices/medicines assimilated into Indian culture. Such traditional medicines recognized by the board of CAM, government of India are (AYUSH - Ayurveda, yoga, unani, siddha and homeopathy).

Integrative oncology is a combination of one where Complementary and Alternative Medicine (CAM) with conventional cancer treatment modalities is used to control side-effects, improve the state of mental wellbeing, manage symptoms.

In Ancient texts, the malignant tumors are described as ARBUDA and considered as incurable that are considered as TRIDOSHIKA and ASADHYA. Some (Appx. 30) herbs show anti-tumor activities these can be used as an adjuvant to chemo/radio therapy in controlling the adverse effects & improving the patient’s Quality of Life. Panchakarma is manipulative & body-based practices that focus on musculo-skeletal system to reduce anxiety and pain in cancer patients.

Homeopathy can alleviate the stress and trauma of cancer patients and decrease the side-effects of radio and chemo therapy. Acupuncture, is a non-Indian traditional system can be used as an adjuvant in treating nausea, vomiting, pain, xerostomia& effective in reducing lymphedema. However, Acupuncture is contra-indicated in severe neutropenia or thrombocytopenia and at the site of primary/metastatic tumor.
Yoga, the mind - body medicine is a nondrug therapy which focuses on the interaction among brain, mind, body and behavior to improve function, Health and Quality of Life. It has proved to reduce anxiety, insomnia and stress.

The holistic approach must be followed in designing cancer treatment must include Mechanistic studies, Potential Herb drug interaction, Pharmacokinetics, Bio-availability & Clinical trials in traditional drugs, Practices that are formulated with dosage, Safety & efficacy with chemo-radiotherapy.

The mission of Integrated Oncology should be to make the cancer patients Live and not just to Exist.
