Lifestyle Factors and Cancer: A Narrative Review.

Lifestyle factors and their impact on cancer prevention, prognosis, and survivorship are increasingly recognized in the medical literature. Lifestyle factors are primarily defined here as diet and physical activity. We conducted a narrative review of the primary published data, including randomized controlled trials and prospective studies, on the impact of primary lifestyle factors on oncogenesis and clinical outcomes in the preventative and survivorship setting. First, we discuss the oncogenic mechanisms behind primary lifestyle factors (diet, physical activity and, within these 2, obesity). Then, we discuss the impact of adherence to lifestyle guidelines and dietary patterns on cancer incidence based on primary data. Owing to the plethora of published literature, to summarize the data in a more efficient manner, we describe the role of physical activity on cancer incidence using summative systematic reviews. We end by synthesizing the primary data on lifestyle factors in the survivorship setting and conclude with potential future directions. In brief, the various large-scale studies investigating the role diet and physical activity have reported a beneficial effect on cancer prevention and survivorship. Although the impact of single lifestyle factors on cancer incidence risk reduction is generally supported, holistic approaches to address the potential synergistic impact of multiple lifestyle factors together in concert is limited. Future research to identify the potentially synergistic effects of lifestyle modifications on oncogenesis and clinical outcomes is needed, particularly in cancer subtypes beyond colorectal and breast cancers.

The sharks are circling: a qualitative study of living with metastatic breast cancer.

PURPOSE: The purpose of this phenomenological study was to gain an understanding of the intersection of continued treatment and quality of life in women living with metastatic breast cancer (MBC). METHODS: This was a qualitative study in which women with MBC were interviewed about their perceptions how MBC affected their physical, emotional, and role functioning. RESULTS: Participants (n = 16) were mostly Caucasian (86.7%) and non-Hispanic (93.3%). The mean age was 55.62 years. Most women were on their third or greater line of treatment (68.5%). Themes identified from analysis of the transcripts revealed the following: (1) shock and devastation of the initial diagnosis; (2) feeling as if the sharks are circling; (3) cancer is a rollercoaster with never-ending treatments; (4) individual definitions of quality of life; and (5) you are not the person you once were. CONCLUSIONS: Symptoms, ongoing treatments, treatment changes, and disease progression negatively influence physical, emotional, and role function. Women with MBC define quality of life in different ways, and while symptoms and functional limitations are present, the cancer experience causes some to reevaluate their lives and focus on their individual priorities and values. IMPLICATIONS FOR CANCER SURVIVORS: Although newly developed treatments increase survival among women with MBC, the symptoms, concerns, and issues surrounding QOL remain unresolved. The relatively high price of continuous treatment and disease exacerbation is indicative of the need for multi-pronged intervention strategies that address physical, mental, and emotional aspects of living with MBC.

Atypical hyperplasia of the breast: Clinical cases and management strategies.

Atypical hyperplasia of the breast is a histopathologic lesion identified incidentally on image-guided breast biopsy. It is associated with a substantial increase in lifetime risk for breast cancer. Clinicians should counsel women with atypical hyperplasia regarding risk-reducing strategies, which include preventive endocrine therapy options, enhanced surveillance imaging, and lifestyle modifications. In this review, we describe 5 different but common clinical case scenarios for atypical hyperplasia of the breast and review management strategies for each scenario.

Sexual Health after a Breast Cancer Diagnosis: Addressing a Forgotten Aspect of Survivorship.

Breast cancer is the most common cancer in women. The life expectancy after a breast cancer diagnosis is improving steadily, leaving many more persons with the long-term consequences of treatment. Sexual problems are a common concern for breast cancer survivors yet remain overlooked in both the clinical setting and the research literature. Factors that contribute to sexual health concerns in breast cancer survivors are biopsychosocial, as are the barriers to addressing and treating these health concerns. Sexual health needs and treatment may vary by anatomy and gender. Multidisciplinary management may comprise lifestyle modifications, medications, sexual health aids such as vibrators, counseling, and referrals to pelvic health physical therapy and specialty care. In this article, we review the contributing factors, screening, and management of sexual difficulties in cisgender female breast cancer survivors. More information is needed to better address the sexual health of breast cancer survivors whose sexual/gender identity differs from that of cisgender women.

Lifestyle for breast cancer risk reduction.

Primary prevention is the most cost-effective long-term strategy for reducing breast cancer occurrence. Lifestyle education centered on the 2018 American Institute for Cancer Research Cancer Prevention Recommendations, offered as a package, should be a core component of routine patient visits. The key components of the recommendations include maintenance of a normal weight; following a low-fat, whole-food, plant-predominant diet rich in whole grains, fruit, and vegetables; regular physical activity; and alcohol avoidance.

Cancer treatment-specific medication beliefs among metastatic breast cancer patients: a qualitative study.

BACKGROUND/SIGNIFICANCE: Over 168,000 women are living with metastatic breast cancer (MBC) in the USA. More efficacious treatments have lengthened overall survival, but these treatments often result in a myriad of symptoms and financial burden that may negatively impact perceptions of cancer treatment and medication-taking behavior. PURPOSE: To explore cancer treatment-specific medication beliefs among women undergoing cancer treatment for MBC. METHODS: A qualitative study was conducted using semi-structured interviews that were audio recorded and transcribed verbatim. A thematic analysis was conducted using ATLAS.ti 8.0 software. Inter-rater reliability was set at a threshold of 0.80. Participants were recruited from a National Cancer Institute-designated comprehensive care center. Eligibility included ≥18 years old, English speaking, confirmed MBC diagnosis, and able/willing to complete interviews via telephone or Zoom. RESULTS: Participants (n = 16) were largely Caucasian (86.7%) and non-Hispanic (93.3%). Mean age was 55.62 years. Three major themes were revealed, with corresponding subthemes: (1) positive cancer treatment-specific medication beliefs highlighting the benefit of treatment (relief of cancer-related symptoms and medication efficacy: delayed disease progression/extended survival); (2) negative cancer treatment-specific medication beliefs that caused concern for cancer treatment (medication symptoms, side effects and drug-drug interactions, financial toxicity, lack of guarantee medication would work); and (3) dialectical cancer treatment-specific medication beliefs indicating the benefits of cancer treatment outweigh the risks. CONCLUSION: Overall, participants noted that the benefits of cancer treatment outweighed the risks in the context of metastatic disease. Participants understood their prognosis and that they depended on their cancer treatment for survival. Oncology providers should continue to assess and address medication beliefs over the treatment trajectory and assist MBC patients with the decisional balance between the risk and benefit of continued cancer treatment.

Identifying and Managing Patients with Elevated Breast Cancer Risk Presenting for Screening Mammography.

BACKGROUND: Identifying the prevalence and management of patients at high-risk for breast cancer can improve resource utilization and provide individualized screening strategies. OBJECTIVE: The purpose of this study was to identify the prevalence of high-risk patients in our institution who presented for screening mammography and to understand how they utilized downstream resources offered to them. MATERIALS AND METHODS: This single institution retrospective study utilized the Tyrer-Cuzick risk assessment model to provide lifetime risk of breast cancer of patients presenting for screening mammography over a one-year period. Their subsequent management and resource utilization were collated. RESULTS: High-risk patients comprised 7.7% (701/9061) of our screening population. Of those high-risk women offered a Breast Center (BC) consultation, 75.2% (276/367) participated in the consultation, with 51.1% (141/276) of those patients completing MRI for supplemental screening. Risk reducing medication was adopted by 7.6% (6/79) of those offered. Of patients offered a genetics consultation, 66.3% (53/80) participated in the consultation, and 50.0% (40/80) completed genetic testing. CONCLUSIONS: Identifying and understanding high-risk patient cohorts, whether locally or in a population-based context, is important for individualized patient care and practice efficiency.

Pre-diagnosis major life stressors and breast cancer outcomes.

PURPOSE: While the association between diagnosis of breast cancer and post-diagnosis psychological distress has been well documented, data regarding pre-diagnosis psychological distress in the breast cancer population are limited. Here, we assessed pre-diagnosis major life stressors and breast cancer outcomes, namely stage of disease and choice of surgery, in a single-center population. METHODS: Patients with newly diagnosed clinical stage 0-3 breast cancer seen at Mayo Clinic Florida between June 11, 2018, and October 7, 2019, were administered voluntary telephone surveys to assess major life stressors during the 24 months preceding their cancer diagnosis. Subsequent clinical outcomes of cancer stage at diagnosis and surgical treatment were obtained through retrospective chart review. Study subjects who had experienced major life stressors and those who had not were compared using Chi-square tests. RESULTS: Of 222 patients who were included, 51.3% reported experiencing a major life event before breast cancer diagnosis. 43.9% of these patients endorsed family-related stress. 21.1% had experienced multiple stressors. 1.8% described financial stress. Although more patients in the group with pre-diagnosis stress had carcinoma in situ (21.1% versus 13.0%, p = 0.11) and fewer had stage T1/T2 disease (64% versus 73.1%, p = 0.14) than in the group without stress, these differences were not statistically significant. More patients with pre-diagnosis stress chose mastectomy (34.2% versus 22.2%, p = 0.048). CONCLUSIONS: Psychological distress is prevalent prior to breast cancer diagnosis and may merit early intervention. While additional study in diverse populations is needed, current data suggest possible associations between pre-diagnosis psychological distress and surgical decision making, specifically mastectomy.

Preventing Breast Cancer Through Identification and Pharmacologic Management of High-Risk Patients.

Breast cancer remains the most common cancer in women in the United States. For certain women at high risk for breast cancer, endocrine therapy (ET) can greatly decrease the risk. Tools such as the Breast Cancer Risk Assessment Tool (or Gail Model) and the International Breast Cancer Intervention Study risk calculator are available to help identify women at increased risk for breast cancer. Physician awareness of family history, reproductive and lifestyle factors, dense breast tissue, and history of benign proliferative breast disease are important when identifying high-risk women. The updated US Preventive Services Task Force and American Society of Clinical Oncology guidelines encourage primary care providers to identify at-risk women and offer risk-reducing medications. Among the various ETs, which include tamoxifen, raloxifene, anastrozole, and exemestane, tamoxifen is the only one available for premenopausal women aged 35 years and older. A shared decision-making process should be used to increase the usage of ET and must be individualized. This individualized approach must account for each woman's medical history and weigh the benefits and risks of ET in combination with the personal values of the patient.

Current Management and Treatment Options for Breast Pain.

Breast pain is a commonly experienced symptom in women of all ages and can significantly impact quality of life. Fear of cancer prompts many patients to report their pain, although risk for malignancy is low in the absence of a palpable mass or other abnormal finding on breast examination. All patients with breast pain should have a thorough history and physical examination to determine if diagnostic imaging is indicated. Management of breast pain without anatomic or radiographic abnormalities depends on pain type and severity. Often, no intervention is required. However, for women with pain that adversely impacts daily living, short-term therapies may be considered. For mild to moderate pain, a trial of conservative, nonpharmacologic strategies should be tried first. For those with severe symptoms impacting quality of life, a trial of pharmacologic therapy can be considered after appropriate counseling for medication-related adverse effects. Herein, we have provided a concise summary of a generalized approach to classification, assessment, and management of breast pain.

Integrative Therapies During and After Breast Cancer Treatment: ASCO Endorsement of the SIO Clinical Practice Guideline.

Purpose The Society for Integrative Oncology (SIO) produced an evidence-based guideline on use of integrative therapies during and after breast cancer treatment that was determined to be relevant to the American Society of Clinical Oncology (ASCO) membership. ASCO considered the guideline for endorsement. Methods The SIO guideline addressed the use of integrative therapies for the management of symptoms and adverse effects, such as anxiety and stress, mood disorders, fatigue, quality of life, chemotherapy-induced nausea and vomiting, lymphedema, chemotherapy-induced peripheral neuropathy, pain, and sleep disturbance. Interventions of interest included mind and body practices, natural products, and lifestyle modifications. SIO systematic reviews focused on randomized controlled trials that were published from 1990 through 2015. The SIO guideline was reviewed by ASCO content experts for clinical accuracy and by ASCO methodologists for developmental rigor. On favorable review, an ASCO Expert Panel was convened to review the guideline contents and recommendations. Results The ASCO Expert Panel determined that the recommendations in the SIO guideline-published in 2017-are clear, thorough, and based on the most relevant scientific evidence. ASCO endorsed the guideline with a few added discussion points. Recommendations Key recommendations include the following: Music therapy, meditation, stress management, and yoga are recommended for anxiety/stress reduction. Meditation, relaxation, yoga, massage, and music therapy are recommended for depression/mood disorders. Meditation and yoga are recommended to improve quality of life. Acupressure and acupuncture are recommended for reducing chemotherapy-induced nausea and vomiting. Acetyl-l-carnitine is not recommended to prevent chemotherapy-induced peripheral neuropathy because of a possibility of harm. No strong evidence supports the use of ingested dietary supplements to manage breast cancer treatment-related adverse effects.

Trends in Sexual Function After Breast Cancer Surgery.

PURPOSE: Sexual dysfunction is assumed to be common, but understudied, in breast cancer patients. Herein, we use the validated female sexual functioning index (FSFI) to evaluate changes in female sexual function after breast cancer surgery. METHODS: The FSFI assesses sexual function in six domains (desire, arousal, lubrication, orgasm, satisfaction, pain) on a 36-point scale, with scores >26.6 indicating better sexual function. We identified 226 women with unilateral breast cancer undergoing surgery at our institution from June 2010-January 2015. All completed the FSFI preoperatively and at a median of 13 months postoperatively. We quantified declines in FSFI scores and considered p-values <0.05 statistically significant. RESULTS: Overall, 119 women had breast-conserving surgery (BCS), 40 had unilateral mastectomy (UM), and 67 had UM plus contralateral prophylactic mastectomy (CPM). All women had similar baseline FSFI scores (medians: BCS, 26.3; UM, 25.2; UM+CPM, 23.7; p = 0.23). At follow-up, sexual function had declined significantly in BCS (23.5; p < 0.001) and UM (17.4; p = 0.010), but was unchanged in UM+CPM (22.8; p = 0.74) women. Interestingly, all women maintained their desire for sex (p = 0.17). BCS and UM women demonstrated significant declines in all other subscale domains (all p < 0.045). UM+CPM women demonstrated no decline in any subscale domain, yet did not exhibit superior sexual function to those having UM or BCS (medians: BCS, 23.5; UM, 17.4; UM+CPM, 22.8; p = 0.21). CONCLUSIONS: Baseline sexual dysfunction exists in women diagnosed with breast cancer. Surgery negatively impacts sexual function. Patients who choose mastectomy do not exhibit superior sexual function over those having BCS at 13 months following surgery.
