Background
• Use of Complimentary & Alternative system of Medicine [CAM]
by cancer patients has increased over last 15 years. [1,2]
• Use of CAM by cancer patients in Europe is about 35.9% [Range
of 14.8% - 73.1% across countries]. [1]
• Increasing use of CAM for cancer from Turkey [54% - 61%],
Thailand [60%] & China [93.4%]. [3-5]
•
Beliefs / reasons for use of CAM are: 1. Directly fights against
cancer (31.1%) 2. Adjuvant to conventional treatment (25.2%),
3. Reduces suffering from allopathic treatment (33.1%). [6]
Objectives
• To know the proportion of cancer patients using
complementary and alternative medicine [CAM] in tertiary
care hospital
• To know the patterns of usage of CAM among Cancer patients.
• To know the reasons and perceptions for preferring CAM.
Materials & Methods
• Study design: This is a interview based Cross sectional study.
• Study Setting: Tertiary care cancer hospital of Kasturba Medical
College [Manipal University].
• Study Population: Cancer patients admitted for treatment. Those who
were 1. moribund, 2. could not respond to questionnaire were
excluded.
• Sample Size: Using the formula for finite population [N = Z2PQ / d2 ],
assuming that at least 40% have used CAM, for 95% Confidence
Interval, a power of 80% & 10% non-response, the sample size was
144.
• Sampling: Non-random sampling.
Materials & Methods
• Study Instrument: An interview schedule was prepared in the local
language to know: 1. Socio demographic characteristics of study
participants, 2. Patterns of CAM usage, 3. Reasons for preference and
perception about CAM
• Pre-testing: This was pretested and modified to suit our study.
Interview was conducted by trained medical students well versed with
local language.
• The research protocol was approved by the Institutional Ethics
Committee.
• Data Collection: Interviews were conducted in the hospitals after
obtaining informed consent.
Data Analysis: Was done using SPSS Version 10. The results are
presented in Tables. Chi-square test was used. ‘p’ < 0.05 was
considered significant.
Results
• Totally 154 cancer patients participated in the study
• Half [n=78; 50.6%] were between 41-60 years of age. Females were
than males [n=91; 59.1%].
• Majority [n=123; 83.7%] of them were married.
• Most [n=109; 70.78%] of them were educated up to secondary school.
• Skilled & semiskilled occupation [n=62; 40.2%] constituted majority.
About a third [n=55; 35.7%] were women who were not employed.

Discussion
1. Proportion
• Proportion of CAM users was 33.8%. This is with in the range reported
from studies conducted in other countries [14.8% to 93.4%]. [1-5]
• Studies conducted among patients suffering from a specific type of cancer
reported a higher percentage of CAM use.
2. Types of CAM
• We found that Ayurveda & herbal medicine was the most common CAM
used. Other studies reported use of supplements (herbs or vitamins). [1-5]
• CAM usage associated with cultural beliefs. So the preference for Ayurveda
in India.
Beliefs and Perceptions for CAM use
• Most patients were simply trying everything that could help
(84.6%). Similar findings reported from other studies. [1-5]
Conclusions
• About 33.8% used CAM. Majority (96.2%) of CAM users were
satisfied with allopathy. Half of them used CAM as an adjuvant to
Allopathy.
• Limitations: 1. Repsonse bias 2. Study limited to one tertiary care
center.
