Breast cancer is a type of cancer originating from breast tissue, most commonly from the inner lining of milk ducts or the lobules that supply the ducts with milk. Cancers originating from ducts are known as ductal carcinomas, while those originating from lobules are known as lobular carcinomas. The benefit vs. harm of breast cancer screening is controversial. The characteristics of the cancer determine the treatment, which may include surgery, medications (hormonal therapy and chemotherapy), radiation and/or immunotherapy. Surgery provides the single largest benefit, and to increase the likelihood of cure, several chemotherapy regimens are commonly given in addition. Radiation is used after breast-conserving surgery and substantially improves local relapse rates and in many circumstances also overall survival.
Breast cancer staging using the TNM system is based on the size of the tumor (T), whether or not the tumor has spread to the lymph nodes (N) in the armpits, and whether the tumor has metastasized (M) (i.e. spread to a more distant part of the body). Larger size, nodal spread, and metastasis have a larger stage number and a worse prognosis.
Some genetic susceptibility may play a minor role in most cases. Overall, however, genetics is believed to be the primary cause of 5–10% of all cases. In those with zero, one or two affected relatives, the risk of breast cancer before the age of 80 is 7.8%, 13.3%, and 21.1% with a subsequent mortality from the disease of 2.3%, 4.2%, and 7.6% respectively. In those with a first degree relative with the disease the risk of breast cancer between the age of 40 and 50 is double that of the general population.
Grading compares the appearance of the breast cancer cells to the appearance of normal breast tissue. Normal cells in an organ like the breast become differentiated, meaning that they take on specific shapes and forms that reflect their function as part of that organ. Cancerous cells lose that differentiation. In cancer, the cells that would normally line up in an orderly way to make up the milk ducts become disorganized. Cell division becomes uncontrolled. Cell nuclei become less uniform. Pathologists describe cells as well differentiated (low grade), moderately differentiated (intermediate grade), and poorly differentiated (high grade), as the cells progressively lose the features seen in normal breast cells. Poorly differentiated cancers (the ones whose tissue is least like normal breast tissue) have a worse prognosis.
The main stages are:
• Stage 0 is a pre-cancerous or marker condition, either ductal carcinoma in situ (DCIS) or lobular carcinoma in situ (LCIS).
• Stages 1–3 are within the breast or regional lymph nodes.
• Stage 4 is ‘metastatic’ cancer that has a less favorable prognosis.
ER+ cancer cells (that is, cancer cells that have estrogen receptors) depend on estrogen for their growth, so they can be treated with drugs to block estrogen effects (e.g. tamoxifen), and generally have a better prognosis. Untreated, HER2+ breast cancers are generally more aggressive than HER2- breast cancers, but HER2+ cancer cells respond to drugs such as the monoclonal antibody trastuzumab (in combination with conventional chemotherapy), and this has improved the prognosis significantly. Cells that do not have any of these three receptor types (estrogen receptors, progesterone receptors, or HER2) are called triple-negative.
Resistance to Systemic Therapy in Patients with Breast Cancer
Breast cancer is the most common cancer and the second leading cause of cancer death in American women. It was the second most common cancer in the world in 2002, with more than 1 million new cases. Despite advances in early detection and the understanding of the molecular bases of breast cancer biology, about 30% of patients with early-stage breast cancer have recurrent disease. To offer more effective and less toxic treatment, selecting therapies requires considering the patient and the clinical and molecular characteristics of the tumor. Systemic treatment of breast cancer includes cytotoxic, hormonal, and immunotherapeutic agents. These medications are used in the adjuvant, neoadjuvant, and metastatic settings. In general, systemic agents are active at the beginning of therapy in 90% of primary breast cancers and 50% of metastases. However, after a variable period of time, progression occurs. At that point, resistance to therapy is not only common but expected.
Gonzalez-Angulo et al., (2007) reviewed the general mechanisms of drug resistance, including multidrug resistance by P-glycoprotein and the multidrug resistance protein family in association with specific agents and their metabolism, emergence of refractory tumors associated with multiple resistance mechanisms, and resistance factors unique to host-tumor-drug interactions. Important anticancer agents specific to breast cancer are described.
Breast cancer is the most common type of cancer and the second leading cause of cancer death in American women. In 2002, 209,995 new cases of breast cancer were registered, and 42,913 patients died of it. In 5 years, the annual prevalence of breast cancer will reach 968,731 cases in the United States. World wide, the problem is just as significant, as breast cancer is the most frequent cancer after nonmelanoma skin cancer, with more than 1 million new cases in 2002 and an expected annual prevalence of more than 4.4 million in 5 years. Breast cancer treatment currently requires the joint efforts of a multidisciplinary team. The alternatives for treatment are constantly expanding. With the use of new effective chemotherapy, hormone therapy, and biological agents and with information regarding more effective ways to integrate systemic therapy, surgery, and radiation therapy, elaborating an appropriate treatment plan is becoming more complex. Developing such a plan should be based on knowledge of the benefits and potential acute and late toxic effects of each of the therapy regimens.
Despite advances in early detection and understanding of the molecular bases of breast cancer biology, approximately 30% of all patients with early-stage breast cancer have recurrent disease, which is metastatic in most cases. The rates of local and systemic recurrence vary within different series, but in general, distant recurrences are dominant, strengthening the hypothesis that breast cancer is a systemic disease from presentation. On the other hand, local recurrence may signal a posterior systemic relapse in a considerable number of patients within 2 to 5 years after completion of treatment. To offer better treatment with increased efficacy and low toxicity, selecting therapies based on the patient and the clinical and molecular characteristics of the tumor is necessary.
Consideration of these factors should be incorporated in clinical practice after appropriate validation studies are performed to avoid confounding results, making them true prognostic and predictive factors. A prognostic factor is a measurable clinical or biological characteristic associated with a disease-free or overall survival period in the absence of adjuvant therapy, whereas a predictive factor is any measurable characteristic associated with a response or lack of a response to a specific treatment. The main prognostic factors associated with breast cancer are the number of lymph nodes involved, tumor size, histological grade, and hormone receptor status, the first two of which are the basis for the AJCC staging system. The sixth edition of the American Joint Committee on Cancer staging system allows better prediction of prognosis by stage. However, after determining the stage, histological grade, and hormone receptor status, the tumor can behave in an unexpected manner, and the prognosis can vary. Other prognostic and predictive factors have been studied in an effort to explain this phenomenon, some of which are more relevant than others: HER-2/neu gene amplification and protein expression, expression of other members of the epithelial growth factor receptor family, S phase fraction, DNA ploidy, p53 gene mutations, cyclin E, p27 dysregulation, the presence of tumor cells in the circulation or bone marrow, and perineural and lymphovascular space invasion. Systemic treatment of breast cancer includes the use of cytotoxic, hormonal, and immunotherapeutic agents.
All of these agents are used in the adjuvant, neoadjuvant, and metastatic setting. Adjuvant systemic therapy is used in patients after they undergo primary surgical resection of their breast tumor and axillary nodes and who have a significant risk of systemic recurrence. Multiple studies have demonstrated that adjuvant therapy for early-stage breast cancer produces a 23% or greater improvement in disease-free survival and a 15% or greater increase in overall survival rates. Recommendations for the use of adjuvant therapy are based on the individual patient’s risk and the balance between absolute benefit and toxicity. Anthracycline-based regimens are preferred, and the addition of taxanes increases the survival rate in patients with lymph node-positive disease. Adjuvant hormone therapy accounts for almost two thirds of the benefit of adjuvant therapy overall in patients with hormone-receptor-positive breast cancer. Tamoxifen is considered the standard of care in premenopausal patients. In comparison, the aromatase inhibitor anastrozole has been proven to be superior to tamoxifen in postmenopausal patients with early-stage breast cancer. The adjuvant use of monoclonal antibodies and targeted therapies other than hormone therapy is being studied. Interestingly, some patients have an early recurrence even though they have a tumor with good prognostic features and at a favorable stage. These recurrences have been explained by the existence of certain cellular characteristics at the molecular level that make the tumor cells resistant to therapy. Selection of resistant cell clones of micrometastatic disease has also been proposed as an explanation for these events.
Neoadjuvant systemic therapy, which is the standard of care for patients with locally advanced and inflammatory breast cancer, is becoming more popular. It reduces the tumor volume, thus increasing the possibility of breast conservation, and at the same time allows identification of in vivo tumor sensitivity to different agents. The pathological response to neoadj uvant systemic therapy in the breast and lymph nodes correlates with patient survival. Use of this treatment modality produces survival rates identical to those obtained with the standard adjuvant approach. The rates of pathological complete response (pCR) to neoadjuvant systemic therapy vary according to the regimen used, ranging from 6% to 15% with anthracycline-based regimens to almost 30% with the addition of a noncross-resistant agent such as a taxane. In one study, the addition of neoadjuvant trastuzumab in patients with HER-2-positive breast tumors increased the pCR rate to 65%. Primary hormone therapy has also been used in the neoadjuvant systemic setting. Although the pCR rates with this therapy are low, it significantly increases breast conservation. Currently, neoadjuvant systemic therapy is an important tool in not only assessing tumor response to an agent but also studying the mechanisms of action of the agent and its effects at the cellular level. However, no tumor response is observed in some cases despite the use of appropriate therapy. The tumor continues growing during treatment in such cases, a phenomenon called primary resistance to therapy. The use of palliative systemic therapy for metastatic breast cancer is challenging.
Five percent of newly diagnosed cases of breast cancer are metastatic, and 30% of treated patients have a systemic recurrence. Once metastatic disease develops, the possibility of a cure is very limited or practically nonexistent. In this heterogeneous group of patients, the 5-year survival rate is 20%, and the median survival duration varies from 12 to 24 months. In this setting, breast cancer has multiple clinical presentations, and the therapy for it should be chosen according to the patient’s tumor characteristics, previous treatment, and performance status with the goal of improving survival without compromising quality of life. Treatment resistance is most commonly seen in such patients. They initially may have a response to different agents, but the responses are not sustained, and, in general, the rates of response to subsequent agents are lower.
Isoflavone intake inhibits the development of mammary tumors in normal and ovariectomized rats
A time to another look at the use of phytoestrogens in breast cancer
Considerable epidemiological studies have shown a negative association between soy intake and breast cancer risk (Peeters et al., 2003). Recently, a meta-analysis of prospective studies found that soy isoflavone consumption was not only inversely associated with risk of breast cancer incidence, but also was inversely associated with risk of breast cancer recurrence (Dong et al., 2011). Animal studies have generated conflicting data regarding the ability of isoflavone to reduce mammary tumorigenesis (Gallo et al., 2001; Ueda et al., 2003). In general, most previous studies reported that dietary isoflavone exposure may increase tumor latency (Allred et al., 2004; Peng et al., 2010).
This research paper by Ma et al., (2014) proved that isoflavone intake cannot only increase the mean latent period, but also decrease the tumor incidence. The same results were reported in other animal studies. Hewitt et al., (2003) reported that female Balb/c mice injected with F3II cells and fed diets supplemented with 0.6% soy extract exhibited a significant 90% reduction in mammary tumor weight compared to controls. Moreover, Kang et al., (2009) found that soy phytochemical extraction exerts significant antitumor and anti-angiogenic activity in a postmenopausal animal model with breast cancer.
The mechanisms which isoflavone could alter mammary tumorigenesis are not completely understood. The rat, mouse and human ER exist as two subtypes, ERα and ERβ. The difference in function between the two ER remains to be established, but it is generally assumed that ERα mediates the proliferative actions of estrogens and ERβ may inhibit cellular proliferation by antagonizing the actions of ERα (Lazennec et al., 2001). It is to be noted that ERβ is expressed at a significantly higher level than ERα during early development and in normal adult breast, while in the breast tumor ERα expression is higher than ERβ expression. In addition, isoflavones bind more strongly to ERβ than to ERα (Speirs et al., 2007).
Some studies reported that genistein can exhibit potential anticarcinogenesis activities by the induction of mammary epithelial cell differentiation and activation of ERβ (Kuiper et al., 1998). Recently, Lattrich et al., (2012) tested the effect of ERβ agonists on the growth and gene expression of different ERβ-positive human breast cancer cell lines and found that the ERβ agonists only inhibited the growth of the ERα, ERβ-positive breast cancer cell lines, which suggested that the anti-proliferative effects of the ERβ agonists might be dependent on the presence of both ERs. In the present research, we found that soy isoflavone significantly changed the estrogen receptor expression profiles including the increasing of ERβ expression and ERα expression, which suggested that both ERα and ERβ may be responsible for the inhibition of mammary tumors.
Oxidative stress and increased production of reactive oxygen species (ROS) are involved in various processes of carcinogenesis (Swiatkowska et al., 2002). High level of ROS has been reported to damage many biomolecules and exert diverse cellular changes in gene expression that leads to initiation and promotion of carcinogenesis. Similar, with the results in the present research, Deepalakshmi et al., (2013) have reported that the plasma level of the thiobarbituric acid reactive substances including MDA and 8-OHdG was significantly increased in 7,12-dimethylbenz(a)anthracene (DMBA)-induced breast cancer rats through the overproduction and diffusion of free radicals from the damaged tumor tissues when compared with DMBA-rats. The antioxidant activity of all the soy isoflavones have been proved by ferricreducing ability of plasma assay and Trolox equivalent antioxidant capacity assay in a study (Mitchell et al., 1998).
Since lipid peroxidation is one of the most important expressions of oxidative stress induced by ROS, its end products MDA and 8-OHdG were determined as the oxidative stress indicator in our study. In this present study, the results showed that isoflavone treatment significantly decreased the 8-OHdG content in normal rats and MDA concentrations in ovariectomized rats compared with CG, implicating that this protective effect is probably based on the antioxidant activity of the soy isoflavones which reduces the oxidative damage by blocking the production of free radicals and inhibits lipid peroxidation. Studies have reported that SOD family played a crucial role in ROS scavenging (Kim et al., 2010). Ma et al., (2014) found that isoflavone intake significantly increased SOD content in normal rats but not in ovariectomized rats.
In conclusion, results suggested that isoflavone intake can significantly inhibit the development of mammary tumors in normal rats or in ovariectomized rats through changing the estrogen receptor expression profiles. In addition, antioxidant activity of isoflavone may be also responsible for the carcinogenesis suppression.
