Abstract

Introduction: Breast cancer is the major cause of death worldwide. Urgently treatment is needed. A number of undesired side effects sometimes occur during the conventional therapy of cancer. Bioactive compounds derived from plant are the most popular alternative medicine which may reduce adverse effects. Various herbal compounds have been identified and showed very promising anti-cancer properties.

Methodology: The review was systematically conducted by searching the databases of MEDLINE, PubMed, Web of Knowledge, Google Scholar and Science Direct for original research articles and books using relevant search terms.

Results: The potential of combining phytomedicine or natural products with synthetic drugs or introducing these into conventional treatment regimens are not yet systematically explored. Combinatorial strategy may hold promise in development of therapies and chemoprevention strategies against ER-positive breast tumors.

Discussion: The screening for synergetic effects of such combinations is technically demanding and complex, also in the context of drug/herb interactions, but likely to substantially advance pharmacotherapy and future medicine.

Conclusion: It has been concluded that combined effect may improve the treatment effectiveness in combating proliferation of cancer cells, enhancing therapeutic efficacy, as well as abrogating drug resistance.

Introduction

Cancer is dangerous and deadly disease. Early stage of detection may help to cure or improve the life span of the patient. Worldwide, the 2nd foremost reason of the death is breast cancer. All over the world, the total of women diagnosed with breast tumor is higher than one million [1]. There are several factors associated with the breast tumor, for example old age, gender, diet, a first child being born at an old age, consumption of alcoholic beverages, body movement, family history, intake of progesterone or estrogen, lifestyle and endocrine aspects as well including both exogenous and endogenous. There are some other important factors that lead to breast cancer, like radiation therapy of the breast, previous benign and mammographic density [2]. Male are also have some breast cells and tissue that have the possibility to form breast cancer. Figure 1 demonstrated that how the cancer developed from heathy cells [3].

Stages in Breast Cancer

Stage 0

Describe as non-invasive breast cancers. It consists of three types of breast carcinoma [4].

a) Ductal carcinoma in situ (DCIS): this condition is noninvasive and the abnormal cells are found in lining of the breast duct, but the spreading of the abnormal cells is not outside the tissues of breast.

b) Lobular carcinoma in situ (LCIS): in this condition, the abnormal cells are present in the lobules of the breast. This rarely occurs as invasive cancer. Presence of abnormal cells in lobules increases the risk of breast cancer.

c) Paget disease of the nipple: in this condition, abnormal cells are found in nipple only.

Stage I

It is divided into subcategories known as IA and IB.

a) Stage IA: the cancer measures upto 2 cm or small and not found or spread outside the breast; no lymph nodes are involved

b) Stage IB: small clusters are found in the lymph nodes. There is no tumor in the breast; instead, small groups of cancer cells-larger than 0.2 mm but not larger than 2 mm.

There is a tumor in the breast that is no larger than 2 cm, and there are small groups of cancer cells-larger than 0.2 mm but not larger than 2 mm.

Stage II (invasive)

breast cancer: It is divided into Stage IIa and Stage IIb.

a) Stage IIa: tumor present, 2 cm< tumor<5 cm2. Cancer has not spread to the lymph nodes.

b) Stage IIb: 2 cm<tumor<5 cm2. Cancer spreads to 1 to 3 axillary lymph nodes or to the lymph node near the breastbone.

Stage III (locally advanced)

breast cancer: It is divided into IIIA, IIIB and IIIC.

a) Stage IIIa: tumor >5 cm and cancer spreads to 1 to 3 axillary lymph nodes.

b) Stage IIIb: the tumor spreads to 9 axillary lymph nodes.

c) Stage IIIc: tumor may be of any size causing swelling or ulcer and has spread to chest wall. Cancer has spread to 10 or more axillary lymph nodes.

Stage IV (metastatic) breast cancer

In this stage, the cancer spread to the body, beyond the breast, underarm and internal mammary lymph nodes to other parts of the body near to or distant from the breast (Figure 2).

Methodology

The review was systematically conducted by searching the databases of MEDLINE, PubMed, the Web of Knowledge, Google Scholar, and Science Direct for original research articles and books using relevant search terms or their combinations: “Breast cancer, Anticancer drug, Synergic effect, Herbal agent, Synthetic drugs, Bioactive compounds.” Our search was not limited by date but to all relevant publications available in the English language [5].

Treatment of breast cancer

There are many treatment options for breast cancer like surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy, many chemotherapeutic but they have resistance as well as many adverse effects that prevent their usage [6,7]. Combination of these treatments also be a best approach for some cancers like surgery combined with radiation therapy, or chemotherapy, or with all these three treatments. Combination therapy is given according to the type, size, risk and the stage of the breast cancer. Before surgery, either chemotherapy or radiation therapy is used to shrink a canner cell or tumor, thereby improving the opportunity for complete surgical removal [8].

Combination of synthetic drug and natural drug

Due to the increase risk of breast cancer, combination therapy is urgently needed. Combination therapy is useful for the patients having the last stage of breast cancer which cannot be treated by surgery or radiation therapy. The rational for the combination of plant constituents with each other or with synthetic drugs are multiple. Combination of herbal and synthetic drug improves the bioavailability of one of the drugs through facilitating the transport of the drug, reduces the dose, a change of the biological activity status of a cell the over- coming of bacterial resistance mechanisms by influencing the transport, the permeability or the efflux pump of the bacteria or the overcoming of (multi-)drug resistance mechanisms in cancer or autoimmune diseases [9,10]. Some researchers worked on the combination therapy for the treatment breast cancer as shown in Table 1.

Dietary supplements and nutraceuticals for breast cancer therapy

A wide variety of naturally occurring compounds or bioactives from plant food have been fight against the breast cancer [12]. Most of the bioactive have been identified in vegetables, fruits, barks, leaves, spices, and grains and exhibit chemo-preventive activity [13-21]. Plant extracts contain bioactive compounds for the breast cancer therapy as shown in Table 2.

Discussion

In the national and international context of research into development of drug delivery systems, the combination therapy is the highest significance. Combination of drug targeting to breast cancer through suitable carrier system have become widely advantageous with less side effects [22-29]. The treatment of cancer is expensive, because the prescribed drugs are costly and have taken over a long period of time. Alone some synthetic drugs have various side effects due to its high dose, low solubility, low bioavailability [30-34]. So, it is important to deliver the synthetic drugs along with the natural supplement to overcome their problems. In this scenario, combination therapy is expected to reduce the dosage regimen such that the cost of the treatment and associated adverse events are reduced considerably. Such a therapy will not only be commercially successful but also helpful to the society. Side effects of conventional drug have been minimized by conjugation with natural drug and they increase the quality of life of patients [35-41].

Conclusion

Herbal remedies play an important role in the management of breast cancer. Use of herbs as an adjunct to chemotherapy not only exhibits therapeutic efficacy but is also cost effective. Plant extracts contain bioactive compounds that have been used as medicines. Combination of natural and synthetic drugs proved to be an alternate strategy to generate synergistic anticancer specially for breast cancer effects, reduced toxicity associated with individual drug, suppress resistance associated with multiple drugs and enhance the treatment effect. Combination therapy also helps to reduce the dose of the individual drug as well as improves the therapeutic efficacy [42-50].
