TITLE OF THE RESEARCH PROJECT Adjuvant Homoeopathic Management for breast cancer patients experiencing side effects from chemotherapyAn observational pilot study 2. PROJECT SUMMARY An observational pilot study of homoeopathic medicines in combating the side effects of chemotherapy in breast cancer patients will be carried out by Central Council for Research in Homoeopathy, at its Dr. Anjali Chatterjee Regional Research Institute for Homoeopathy, Kolkata. Female participants 18 years and above, having breast cancer and presenting with side effects of chemotherapy shall be enrolled in the study. Homoeopathic medicines shall be used in the study. Assessment shall be done as per Edmonton Symptom Assessment Scale (Revised Version), EORTC QLQ-C30 and QLQBR23. On conclusion of the study, the data obtained shall be statistically analyzed with the help of a suitable statistical package (SPSS statistical package version 16) to see the usefulness of homoeopathic medicines in combating the side effects of chemotherapy and the results shall be disseminated to the medical fraternity. 3. JUSTIFICATION FOR THE STUDY AND USE OF THE RESULTS Chemotherapy is the use of anticancer drugs to treat cancerous cells. Chemotherapy has been used for many years and is one of the most common treatments for cancer. In most cases, chemotherapy works by interfering with the cancer cell's ability to grow or reproduce. Different groups of drugs work in different ways to fight cancer cells. Chemotherapy may be used alone for some types of cancer or in combination with other treatments such as radiation or surgery. Often, a combination of chemotherapy drugs is used to fight a specific cancer. Certain chemotherapy drugs may be given in a specific order depending on the type of cancer it is being used to treat. While chemotherapy can be quite effective in treating certain cancers, chemotherapy drugs reach all parts of the body, not just the cancer cells. Because of this, there may be many side effects during treatment. 1Homoeopathic literature has many drugs in its armamentarium which can combat the side effects of chemotherapy. Therefore, the present study is proposed to find the usefulness of homoeopathic medicines. The result of this study will help the profession to get valid data about the usefulness of homoeopathic medicines in better management of side effects of chemotherapy. 4. BACKGROUND Although no documented study is found on the treatment of side effects of chemotherapy with Homoeopathy but there are evidences of positive role of Homoeopathy in cancer. In a prospective observational study on 45 patients with CA Breast, 38 had hot flushes. Other symptoms like mood disturbances, joint pains, fatigue, sleeplessness, etc. were also present in these patients. Significant improvement was seen in HF and quality of life also showed an improvement.2 CONFIDENTIAL 5 This material is the property of the Central Council for Research in Homoeopathy. Do not disclose or use except as approved by competent authority CLINICAL RESEARCH PROTOCOL In a prospective observational study of Homeopathic treatment of radiation-induced itching in breast cancer patients, twenty-five patients were treated homeopathically for radiation-induced itching. Altogether 21 of 25 (84percent) patients were successfully treated.3 A randomized double-blind placebo-controlled clinical trial involving 66 patients who had been operated on for breast cancer and were undergoing radiotherapy was conducted. The differences of the scores of the Index of Total Severity during Radiotherapy were not statistically significant, but showed a trend towards a better activity of the homoeopathic medicine compared to placebo. Analysis of the data on Total Severity during recovery, showed a statistically significant benefit of the active medicines over placebo.4 A prospective observational study with cancer patients in two differently treated cohorts: one cohort with patients under complementary homeopathic treatment (HG; n=259), and one cohort with conventionally treated cancer patients (CG; n=380). An improvement of quality of life as well as a tendency of fatigue symptoms to decrease in cancer patients under complementary homeopathic treatment was observed.5 Four ultra-diluted remedies (Carcinosin, Phytolacca, Conium and Thuja) were studied against two human breast adenocarcinoma cell lines (MCF-7 and MDA-MB-231) and a cell line derived from immortalized normal human mammary epithelial cells (HMLE). The remedies exerted preferential cytotoxic effects against the two breast cancer cell lines, causing cell cycle delay/arrest and apoptosis.6 In a trial of postoperative adjuvant chemotherapy women with primary breast cancer and spread to one or more axillary nodes were randomised to receive a six-month course of either the single agent chlorambucil or the five-drug combination of chlorambucil, methotrexate, fluorouracil, vincristine, and adriamycin. On completing the treatment 47 patients were asked to fill in questionnaires at home on the side effects of treatment and its influence on the quality of their life. Side effects including nausea, vomiting, malaise, and alopecia had been severe enough to interfere with their lifestyle in 9 (42%) of the patients who had received the single agent and 19 (79%) of those who had received multipledrug treatment. Various other side effects were reported by a few patients.7 5. STUDY OBJECTIVES 5.1. Primary Objective To study the usefulness of homoeopathic medicines for combating the side effects of chemotherapy in breast cancer 5.2. patients using Edmonton Symptom Assessment Scale (Revised Version)8 Secondary Objectives 6. To study the usefulness of homoeopathic medicines in the treatment of cancer patients The quality of life using EORTC QLQ-C30 and QLQ-BR239 To see the changes in CA 15.3 after Homoeopathic treatment To find the clinical symptoms of homeopathic medicines used during trial, if any to enrich the Materia Medica. Operational Definition of Variables I. Common Side effects of Chemotherapeutic drugs used for breast cancer therapy10 Anorexia Nausea CONFIDENTIAL 6 This material is the property of the Central Council for Research in Homoeopathy. Do not disclose or use except as approved by competent authority CLINICAL RESEARCH PROTOCOL Vomiting Diarrhoea Constipation Stomatitis Hair loss Altered mental status including anxiety, depression and drowsiness Local irritation Rash Dermatitis Facial flushing Conjunctivitis Lachrymation Myalgia Sensory neuropathy Fever and flu like symptoms Decrease in blood counts II. Edmonton Symptom Assessment Scale: (Revised Version) The ESAS has been revised to improve ease of understanding and completion for patients. The revised version of the tool is known as the ESAS-r. The ESAS-r is intended to capture the patient’s perspective on symptoms. However, in some situations it may be necessary to obtain a caregiver’s perspective. The ESAS-r provides a profile of symptom severity at a point in time. Repeated assessments may help to track changes in symptom severity over time. The ESAS-r is only one part of a holistic clinical assessment. It is not a complete symptom assessment in itself. III. Health Related Quality of Life: EORTC QLQ-C30 and QLQ-BR23 The European Organisation for Research and Treatment of Cancer quality of life questionnaire and breast cancer subscale are chosen for the reliability and generalisability for this specific cancer patient group. IV. Centesimal potencies The potencies used in centesimal scale are known as centesimal potencies. This was introduced by Dr. C. F. S. Hahnemann in 5th edition of Organon of Medicine in aphorism 270. V. Aggravation Heightening of present symptoms of patient or overall worsening of patient’s condition. It may be of three types: Homoeopathic Aggravation: Because homoeopathic medicines are capable of producing similar symptoms as those of disease symptoms in somewhat higher degree, symptoms seems to be aggravated, after administering the most correct similimum ,this is called as homoeopathic aggravation. A quick and short homoeopathic aggravation is mostly desired after administration of homoeopathic medicines. Medicinal Aggravation: Because of overdosing of medicines or when a partially indicated medicine is applied, some of the medicinal symptoms (non-homoeopathic symptoms) appear in a patient which is called as medicinal aggravation. Disease Aggravation: As a process of natural history of disease, disease condition aggravates which is called as disease aggravation. This happens when a wrong medicine has been employed VI. Amelioration/ relief Decrease in symptom score or improvement in general condition of patient or both is called as Amelioration or relief. CONFIDENTIAL 7 This material is the property of the Central Council for Research in Homoeopathy. Do not disclose or use except as approved by competent authority CLINICAL RESEARCH PROTOCOL VII. Status quo No change in patient’s condition. VIII. Adverse event An adverse event is any symptom, sign, illness or experience that develops or worsens in severity during the course of the study. Intercurrent illnesses or injuries not responding to homoeopathic treatment should also be regarded as adverse events. 7.
