ABSTRACT

INTRODUCTION: This systematic scoping review compares the toxicities experienced by patients receiving immune checkpoint inhibitors (ICIs) or targeted therapy (TT) for stage III (resected and unresectable) and stage IV melanoma. METHODS: OVID Medline, Embase, and PsycInfo were searched to identify Phase III trials reporting toxicities of FDA-approved ICIs and TT for advanced melanoma. AEs that were reported by ≥ 10% of patients in the evaluated trials were included. RESULTS: Toxicity profiles of 11208 patients from 24 studies were reviewed. The rate of AEs was lower with ICIs compared to TT. However, ICIs were associated with higher rates of long-term or permanent AEs compared to TT, where toxicities generally were shortterm and reversible with treatment discontinuation. CONCLUSION: The toxicity profiles of ICIs and TT vary substantially. Whilst the rate of AEs was lower with ICIs than during TT, it was also associated with higher rates of potentially chronic AEs.

ABSTRACT

PURPOSE: To develop optimal cancer survivorship care programs, this study assessed the quality of prostate cancer follow-up care as experienced by patients shortly after completion of primary treatment. METHODS: We surveyed 402 patients with localized prostate cancer participating in a randomized controlled trial comparing specialist versus primary care-based follow-up. For the current study, we used patient-reported data at the time of the first follow-up visit at the hospital, prior to randomization. We assessed patients' ratings of the quality of follow-up care using the Assessment of Patient Experiences of Cancer Care survey. This survey includes 13 scales about different aspects of care and an overall rating of care. Multivariable linear regression analysis was used to identify factors associated with perceived follow-up quality. RESULTS: Patients reported positive experiences at first follow-up for 9 of 13 scales, with mean (M) scores ranging from 79 to 97 (on a 0-100 response scale). Patients reported most frequently (over 70%) suboptimal care regarding symptom management (84%; M = 44, SD = 37), health promotion (75%; M = 45, SD = 39), and physician's knowledge about patients' life (84%; M = 65, SD = 23). Overall, patients' lower quality of follow-up ratings were associated with younger age, higher education level, having more than one comorbid condition, having undergone primary surgery, and experiencing significant symptoms. CONCLUSION: Patients with prostate cancer are generally positive about their initial, hospital-based follow-up care. However, efforts should be made to improve symptom management, health promotion, and physician's knowledge about patients' life. These findings point to areas where prostate cancer follow-up care can be improved.

ABSTRACT

Background: A randomized controlled trial (RCT) is currently comparing the effectiveness of specialist- versus primary care-based prostate cancer follow-up. This process evaluation assesses the reach and identified constructs for the implementation of primary care-based follow-up. Methods: A mixed-methods approach is used to assess the reach and the implementation through the Consolidated Framework for Implementation Research. We use quantitative data to evaluate the reach of the RCT and qualitative data (interviews) to indicate the perspectives of patients (n = 15), general practitioners (GPs) (n = 10), and specialists (n = 8). Thematic analysis is used to analyze the interview transcripts. Results: In total, we reached 402 (67%) patients from 12 hospitals and randomized them to specialist- (n = 201) or to primary care-based (n = 201) follow-up. From the interviews, we identify several advantages of primary care- versus specialist-based follow-up: it is closer to home, more accessible, and the relationship is more personal. Nevertheless, participants also identified challenges: guidelines should be implemented, communication and collaboration between primary and secondary care should be improved, quality indicators should be collected, and GPs should be compensated. Conclusion: Within an RCT context, 402 (67%) patients and their GPs were willing to receive/provide primary care-based follow-up. If the RCT shows that primary care is equally as effective as specialist-based follow-up, the challenges identified in this study need to be addressed to enable a smooth transition of prostate cancer follow-up to primary care.

ABSTRACT

Neoadjuvant ipilimumab and nivolumab induces high pathologic response rates (pRRs) in clinical stage III nodal melanoma, and pathologic response is strongly associated with prolonged relapse-free survival (RFS). The PRADO extension cohort of the OpACIN-neo trial ( NCT02977052 ) addressed the feasibility and effect on clinical outcome of using pathologic response after neoadjuvant ipilimumab and nivolumab as a criterion for further treatment personalization. In total, 99 patients with clinical stage IIIb-d nodal melanoma were included and treated with 6 weeks of neoadjuvant ipilimumab 1 mg kg-1 and nivolumab 3 mg kg-1. In patients achieving major pathologic response (MPR, ≤10% viable tumor) in their index lymph node (ILN, the largest lymph node metastasis at baseline), therapeutic lymph node dissection (TLND) and adjuvant therapy were omitted. Patients with pathologic partial response (pPR; >10 to ≤50% viable tumor) underwent TLND only, whereas patients with pathologic non-response (pNR; >50% viable tumor) underwent TLND and adjuvant systemic therapy ± synchronous radiotherapy. Primary objectives were confirmation of pRR (ILN, at week 6) of the winner neoadjuvant combination scheme identified in OpACIN-neo; to investigate whether TLND can be safely omitted in patients achieving MPR; and to investigate whether RFS at 24 months can be improved for patients achieving pNR. ILN resection and ILN-response-tailored treatment were feasible. The pRR was 72%, including 61% MPR. Grade 3-4 toxicity within the first 12 weeks was observed in 22 (22%) patients. TLND was omitted in 59 of 60 patients with MPR, resulting in significantly lower surgical morbidity and better quality of life. The 24-month relapse-free survival and distant metastasis-free survival rates were 93% and 98% in patients with MPR, 64% and 64% in patients with pPR, and 71% and 76% in patients with pNR, respectively. These findings provide a strong rationale for randomized clinical trials testing response-directed treatment personalization after neoadjuvant ipilimumab and nivolumab.

ABSTRACT

BACKGROUND: During and after systemic therapy, patients with high risk and advanced melanoma experience challenges regarding cancer-related symptoms, treatment-related adverse events, and an impact of these symptoms on their physical and psychosocial well-being. Few studies have investigated the specific needs of these patients and the potential role of eHealth applications in meeting those needs. OBJECTIVE: To explore the supportive care and information needs of high risk and advanced melanoma patients, and how these needs can be supported by eHealth applications. METHODS: In this qualitative study, semi-structured interviews with high risk and advanced melanoma patients during or after systemic treatment were conducted to understand their needs and requirements as possible end-users of mobile eHealth applications. Interview transcripts were independently coded and thematically analyzed. RESULTS: Thirteen participants consented to be interviewed, aged 31 to 71 years. Nearly all patients (n = 12, 92%) experienced unmet information and supportive care needs during and after active treatment. Patients expected to value eHealth applications that facilitate information gathering, wellbeing interventions, and symptom management. The majority of patients (n = 10, 77%) anticipated various advantages from using an eHealth application, including increased autonomy, higher quality of life, and improved disease self-management. DISCUSSION: High risk and advanced melanoma patients have unmet supportive care and information needs during and after systemic treatment. The use of eHealth applications might be an effective way to meet these unmet needs. Patients anticipate a variety of advantages from using these applications, including deriving various benefits from the use of these applications, such as enhanced autonomy.

ABSTRACT

AIMS: Individualized information about the risk of incontinence after prostatectomy could help patients in shared decision-making. METHODS: We compared a historical control cohort (n = 254; between June 2016 and 2017) that received standardized information about the risk of incontinence after robot-assisted radical prostatectomy (RARP) with a prospective patient cohort (n = 254; between June 2017 and May 2018) that received individualized information of the chance of recovery of incontinence within 6 months postoperatively based on the continence prediction tool (CPRED). We measured switch in treatment choice, health-related quality of life (QoL) in both cohorts and the accuracy of the CPRED tool. RESULTS: Patients in the individualized information group with RARP as initial preference switched more often to another treatment than patients who received standardized information (16% vs. 5%; p = 0.001). Patients in the individualized information group with a high risk of incontinence and with RARP as initial preference switched more often to other treatments than patients in intermediate/low risk of incontinence (35% vs. 9.8%; p = 0.001). Patients with a low risk of incontinence choosing RARP after individualized information were less likely to use more than one diaper a day at any time postoperative (p = 0.001) compared to men with an intermediate/high incontinence risk. Overall QoL was worse in patients with incontinence than patients with continence 6 and 12 months after RARP (respectively; p < 0.0001 and p = 0.007). CONCLUSION: Personalized information about the risk of incontinence after RARP makes more patients reconsidering their initial treatment preference. The CPRED correlated strongly with continence outcome after RARP and is a useful tool for shared decision-making.

ABSTRACT

PURPOSE: To understand the role of routine follow-up visits in addressing prostate cancer survivors' supportive care and information needs. METHODS: We audio-recorded follow-up visits of 32 prostate cancer survivors. Follow-up visits were analyzed according to the Verona Network of Sequence Analysis. We categorized survivors' cues, concerns, and questions into five supportive care domains and divided the responses by the healthcare professionals into providing versus reducing space that is to determine whether or not the response invites the patient to talk more about the expressed cue or concern. RESULTS: Prostate cancer survivors mostly expressed cues, concerns, and questions (in the health system and information domain) about test results, potential impotence treatment, follow-up appointments, and (their) cancer treatment during follow-up visits. Survivors also expressed urinary complaints (physical and daily living domain) and worry about the recurrence of prostate cancer (psychological domain). Healthcare professionals were two times more likely to provide space on cues and concerns related to the physical and daily living domain than to psychological related issues. CONCLUSION: Follow-up visits can serve to address prostate cancer survivors' supportive care and information needs, especially on the health system, information, and physical and daily living domain. Survivors also expressed problems in the psychological domain, although healthcare professionals scarcely provided space to these issues. We would like to encourage clinicians to use these results to personalize follow-up care. Also, these data can be used to develop tailored (eHealth) interventions to address supportive care and information needs and to develop new models of survivorship care delivery.

ABSTRACT

Patients with small intestine neuroendocrine tumours (SINETs) face various disease-related symptoms that can affect their social functioning and quality of life. The present study aimed to explore the social consequences of disease-related symptoms in patients with a metastatic SINET and to develop a theory on how these patients experience their disease. Patients were eligible when they were diagnosed with a metastatic SINET between 2009 and 2016 and were younger than 60 years of age during diagnosis, and had a good functional performance status. Semi-structured interviews were conducted between January and June 2018. Data were transcribed and analysed independently by two researchers using grounded theory. Data saturation was reached at 10 interviews and, in total, 12 patients participated. A core component that arose from the interviews was resilience in the face of social consequences of having a metastatic SINET. Prominent physical symptoms were fatigue, diarrhoea and flushes. All of these symptoms were associated with limitations to function in work-related and social activities, as well as feelings of embarrassment and shame. Adaptive strategies, such as careful planning, or focusing on the perspective to live well with a neuroendocrine tumour, helped patients to experience the consequences as less burdensome. Other helpful factors that were identified constituted social support, engaging in meaningful activities and financial stability. Patients with a metastatic SINET experienced social consequences of disease-related symptoms in daily life, although they were able to attenuate the burden of these consequences by using adaptive problem-based, emotion-based and meaning-based coping strategies. Clinicians could explore the perceived consequences and educate patients about adaptive strategies.

ABSTRACT

BACKGROUND: In its 2006 report, From cancer patient to cancer survivor: lost in transition, the U.S. Institute of Medicine raised the need for a more coordinated and comprehensive care model for cancer survivors. Given the ever increasing number of cancer survivors, in general, and prostate cancer survivors, in particular, there is a need for a more sustainable model of follow-up care. Currently, patients who have completed primary treatment for localized prostate cancer are often included in a specialist-based follow-up care program. General practitioners already play a key role in providing continuous and comprehensive health care. Studies in breast and colorectal cancer suggest that general practitioners could also consider to provide survivorship care in prostate cancer. However, empirical data are needed to determine whether follow-up care of localized prostate cancer survivors by the general practitioner is a feasible alternative. METHODS: This multicenter, randomized, non-inferiority study will compare specialist-based (usual care) versus general practitioner-based (intervention) follow-up care of prostate cancer survivors who have completed primary treatment (prostatectomy or radiotherapy) for localized prostate cancer. Patients are being recruited from hospitals in the Netherlands, and randomly (1:1) allocated to specialist-based (N = 195) or general practitioner-based (N = 195) follow-up care. This trial will evaluate the effectiveness of primary care-based follow-up, in comparison to usual care, in terms of adherence to the prostate cancer surveillance guideline for the timing and frequency of prostate-specific antigen assessments, the time from a biochemical recurrence to retreatment decision-making, the management of treatment-related side effects, health-related quality of life, prostate cancer-related anxiety, continuity of care, and cost-effectiveness. The outcome measures will be assessed at randomization (≤6 months after treatment), and 12, 18, and 24 months after treatment. DISCUSSION: This multicenter, prospective, randomized study will provide empirical evidence regarding the (cost-) effectiveness of specialist-based follow-up care compared to general practitioner-based follow-up care for localized prostate cancer survivors.

ABSTRACT

OBJECTIVE: To examine the associations between pharmaceutically treated anxiety and depression and incident cardiovascular disease (CVD) among 1-year prostate cancer survivors. PATIENTS AND METHODS: A registry-based cohort study design was used to describe the risk of incident CVD in adult 1-year prostate cancer survivors without a history of CVD. Patients with prostate cancer diagnosed between 1999 and 2011 were selected from the Netherlands Cancer Registry. Drug dispenses were retrieved from the PHARMO Database Network and were used as proxy for CVD, anxiety, and depression. Data were analysed using Cox regression analysis to examine the risk associations between pharmaceutically treated anxiety and depression entered as a time-varying predictor with incident CVD in 1-year prostate cancer survivors, while controlling for age, traditional CVD risk factors, and clinical characteristics. RESULTS: Of the 5262 prostate cancer survivors, 327 (6%) developed CVD during the 13-year follow-up period. Prostate cancer survivors who were pharmaceutically treated for depression had an increased risk of incident CVD after full adjustment compared to prostate cancer survivors who were not pharmaceutically treated for depression (hazard ratio [HR] 1.51, 95% confidence interval [CI] 1.06-2.15). The increased risk of incident CVD amongst those pharmaceutically treated for depression compared to those who were not pharmaceutically treated for depression, was only valid among: prostate cancer survivors who were aged ≤65 years (HR 2.91; 95% CI 1.52-5.55); those who were not treated with radiotherapy (HR 1.63; 95% CI 1.01-2.65); those who were treated with hormones (HR 1.76; 95% CI 1.09-2.85); those who were not operated upon (HR 1.55; 95% CI 1.07-2.25); and those with tumour stage III (HR 2.21; 95% CI 1.03-4.74) and stage IV (HR 2.47; 95% CI 1.03-5.89). CONCLUSION: Patients with prostate cancer who were pharmaceutically treated for depression had a 51% increased risk of incident CVD after adjustment for anxiety, age, traditional CVD risk factors, and clinical characteristics. The results emphasise the need to pay attention to (pharmaceutically treated) depressed patients with prostate cancer prior to deciding on prostate cancer treatment and for a timely detection and treatment of CVD.

ABSTRACT

INTRODUCTION: As the number of cancer survivors grows, new models of survivorship care are being implemented, but there is limited evaluation to date. This retrospective review assesses the concordance of care provided to adult-onset cancer survivors by advanced practice providers (nurse practitioners and physician assistants) with Institute of Medicine guidelines for survivorship care. METHODS: Records from three survivorship clinics at a single institution were reviewed for frequency of recurrence surveillance, screening for second cancers, symptom management (physical, psychological), health promotion education (alcohol, tobacco, cholesterol, and bone density screenings; diet/exercise discussion), care coordination, and provision of care plan. Data were characterized using descriptive statistics. RESULTS: Over 2 years, 9,052 unique survivorship visits occurred; 210 breast, 208 prostate, and 204 colorectal visits were randomly selected for review. All patients with breast cancer underwent surveillance for recurrence; 99% were screened for new cancers. Discussion of health promotion activities ranged from 83% to 100%; 91% of patients were reviewed for physical symptoms, and 93% were reviewed for psychological symptoms. All patients with prostate cancer underwent recurrence surveillance; 97% were screened for new primaries. Health promotion activities ranged from 70% to 97%, and symptoms were discussed in 89% of visits. All patients with colorectal cancer underwent a surveillance colonoscopy for recurrence; 97% had a carcinoembryonic antigen test. Among women, 97% had mammograms, and 96% had a Papanicolaou test; 83% of men had a prostate-specific antigen test. Health promotion activities ranged from 69% to 100%, and symptoms were discussed in 93% to 97% of visits. CONCLUSIONS: Findings suggest that advanced practice providers can provide survivorship care in accordance with Institute of Medicine standards, which provide a normative standard. This assessment is an important step in evaluating survivorship outcomes.

ABSTRACT

Trastuzumab is associated with cardiotoxicity, manifesting as a decrease of the left-ventricular ejection fraction (LVEF). Administration of anthracyclines prior to trastuzumab increases risk of cardiotoxicity. High-sensitive troponin T and N-terminal-pro-brain natriuretic peptide (NT-proBNP) are molecular markers that may allow earlier detection of drug-induced cardiotoxicity. In this analysis we aimed to quantify the kinetics and exposure-response relationships of LVEF, troponin T and NT-proBNP measurements, in patients receiving anthracycline and trastuzumab. Repeated measurements of LVEF, troponin T and NT-proBNP and dosing records of anthracyclines and trastuzumab were available from a previously published clinical trial. This trial included 206 evaluable patients with early breast cancer. Exposure to anthracycline and trastuzumab was simulated based on available dosing records and by using a kinetic-pharmacodynamic (K-PD) and a fixed pharmacokinetic (PK) model from literature, respectively. The change from baseline troponin T was described with a direct effect model, affected by simulated anthracycline concentrations, representing myocyte damage. The relationship between trastuzumab and LVEF was described by an indirect effect compartment model. The EC50 for LVEF decline was significantly affected by the maximum troponin T concentration after anthracycline treatment, explaining 15.1% of inter-individual variability. In this cohort, NT-proBNP changes could not be demonstrated to be related to anthracycline or trastuzumab treatment. Pharmacodynamic models for troponin T and LVEF were successfully developed, identifying maximum troponin T concentration after anthracycline treatment as a significant determinant for trastuzumab-induced LVEF decline. These models can help identify patients at risk of drug-induced cardiotoxicity and optimize cardiac monitoring strategies.

ABSTRACT

IMPORTANCE: This is the first randomized placebo-controlled evaluation of a medical intervention for the prevention of trastuzumab-related cardiotoxic effects. OBJECTIVE: To determine as the primary end point whether angiotensin II antagonist treatment with candesartan can prevent or ameliorate trastuzumab-related cardiotoxic effects, defined as a decline in left ventricular ejection fraction (LVEF) of more than 15% or a decrease below the absolute value 45%. DESIGN: This randomized, placebo-controlled clinical study was conducted between October 2007 and October 2011 in 19 hospitals in the Netherlands, enrolling 210 women with early breast cancer testing positive for human epidermal growth factor receptor 2 (HER2) who were being considered for adjuvant systemic treatment with anthracycline-containing chemotherapy followed by trastuzumab. INTERVENTIONS: A total of 78 weeks of candesartan (32 mg/d) or placebo treatment; study treatment started at the same day as the first trastuzumab administration and continued until 26 weeks after completion of trastuzumab treatment. MAIN OUTCOMES AND MEASURES: The primary outcome was LVEF. Secondary end points included whether the N-terminal of the prohormone brain natriuretic peptide (NT-proBNP) and high-sensitivity troponin T (hs-TnT) can be used as surrogate markers and whether genetic variability in germline ERBB2 (formerly HER2 or HER2/neu) correlates with trastuzumab-related cardiotoxic effects. RESULTS: A total of 206 participants were evaluable (mean age, 49 years; age range, 25-69 years) 103 in the candesartan group (mean age, 50 years; age range, 25-69 years) and 103 in the placebo group (mean age, 50 years; age range, 30-67 years). Of these, 36 manifested at least 1 of the 2 primary cardiac end points. There were 3.8% more cardiac events in the candesartan group than in the placebo group (95% CI, -7% to 15%; P = .58): 20 events (19%) and 16 events (16%), respectively. The 2-year cumulative incidence of cardiac events was 0.28 (95% CI, 0.13-0.40) in the candesartan group and 0.16 (95% CI, 0.08-0.22) in the placebo group (P = .56). Candesartan did not affect changes in NT-proBNP and hs-TnT values, and these biomarkers were not associated with significant changes in LVEF. The Ala1170Pro homozygous ERBB2 genotype was associated with a lower likelihood of the occurrence of a cardiac event compared with Pro/Pro + Ala/Pro genotypes in multivariate analysis (odds ratio, 0.09; 95% CI, 0.02-0.45; P = .003). CONCLUSIONS AND RELEVANCE: The findings do not support the hypothesis that concomitant use of candesartan protects against a decrease in left ventricular ejection fraction during or shortly after trastuzumab treatment in early breast cancer. The ERBB2 germline Ala1170Pro single nucleotide polymorphism may be used to identify patients who are at increased risk of trastuzumab-related cardiotoxic effects.

ABSTRACT

PURPOSE: Prevailing wisdom suggests that implementation of a survivorship care plan (SCP) will address deficits in survivorship care planning and delivery for cancer patients. Here, we present 24-month results of a randomized clinical trial on health service and patient-reported outcomes among breast cancer patients transferred to their primary care physician for follow-up care. The 24-month assessments represent the long-term benefit and sustainability of the implantation of a SCP. METHODS: In all, 408 patients with early-stage breast cancer were randomized to the SCP or control group. Patient self-completed questionnaires, supplemented with telephone interviews, during the 24-month study period assessed health service and patient-reported outcomes. The primary outcome was cancer-specific distress. Secondary outcomes included health-related quality of life, patient satisfaction, continuity and coordination of care, and health service outcomes such as adherence to guidelines. RESULTS: Over the course of 24 months, there were no differences between both groups in health service and patient-reported outcomes. Women from Quebec compared to those from Western Canada (p < 0.001), women within 2 years of completion of primary treatment compared to a longer period (p = 0.013), and those with a higher SF-36 mental component score compared to a lower score (p = 0.044) were positively associated with adherence to guidelines. CONCLUSION: The implementation of a SCP in the transition of survivorship care from cancer center to primary care did not contribute to improved health service or patient-reported outcomes in this study population. Therefore, additional research is needed before widespread implementation of a SCP in clinical practice.

ABSTRACT

PURPOSE: Therapies for breast cancer may induce hot flashes that can affect quality of life. We undertook a double-blind, placebo-controlled trial with the primary objective of comparing the average daily hot flash scores in the twelfth week among patients treated with venlafaxine, clonidine, and placebo. Additional analyses of the hot flash score over the full 12 weeks of treatment were performed. PATIENTS AND METHODS: In all, 102 patients with a history of breast cancer were randomly assigned (2:2:1) to venlafaxine 75 mg, clonidine 0.1 mg, or placebo daily for 12 weeks. Questionnaires at baseline and during treatment assessed daily hot flash scores, sexual function, sleep quality, anxiety, and depression. RESULTS: After 12 weeks, a total of 80 patients were evaluable for the primary end point. During week 12, hot flash scores were significantly lower in the clonidine group versus placebo (P = .03); for venlafaxine versus placebo, the difference was borderline not significant (P = .07). However, hot flash scores were equal in the clonidine and venlafaxine groups. Over the course of 12 weeks, the differences between both treatments and placebo were significant (P <.001 for venlafaxine v placebo; P = .045 for clonidine v placebo). Frequencies of treatment-related adverse effects of nausea (P = .02), constipation (P = .04), and severe appetite loss were higher in the venlafaxine group. CONCLUSION: Venlafaxine and clonidine are effective treatments in the management of hot flashes in patients with breast cancer. Venlafaxine resulted in a more immediate reduction of hot flash scores when compared with clonidine; however, hot flash scores at week 12 were lower in the clonidine group than in the venlafaxine group.

ABSTRACT

Trastuzumab is standard of care in the treatment of human epidermal growth factor receptor (HER)-2⁺ early and advanced breast cancer. Recently, it has been approved for the treatment of HER-2⁺ advanced gastric cancer. Trastuzumab is an IgG1 humanized monoclonal antibody administered by intravenous infusion on a weekly or three weekly schedule. In all registered indications, trastuzumab is almost always given in combination with chemotherapy. In hormonal receptor-positive breast cancer in postmenopausal women, trastuzumab can be combined with an aromatase inhibitor. Main toxicity is reduction in the left ventricular ejection fraction, which in a minority of patients can become symptomatic, but in many patients is at least partly reversible. Long-term safety needs to be further determined.

ABSTRACT

Young women with breast cancer often experience early menopause as a result of the therapy for their malignant disease. The sudden occurrence of menopause resulting from chemotherapy, oophorectomy, radiation, or gonadal dysgenesis frequently results in hot flashes that begin at a younger age and may occur at a greater frequency and intensity than hot flashes associated with natural menopause. Hormone therapy relieves symptoms effectively in 80%-90% of women who initiate treatment. This therapy, however, is generally contraindicated in estrogen-dependent cancers, such as breast cancer, because of the potentially increased risk for recurrence. Many agents have been investigated as potential means for alleviating hot flashes in survivors of breast cancer, such as progestagens, clonidine, gabapentin, and anti-depressants. Several complementary and alternative medicines frequently used by patients have also been studied. These include black cohosh, phytoestrogens, homeopathy, vitamin E, acupuncture, and behavior strategies. To support the use of one of more of these nonpharmacological or pharmacological options in the treatment of hot flashes in breast cancer patients, more evidence from well-controlled clinical trials is needed. In particular, soundly based scientific research with complementary and alternative medicine therapies is lacking. Pharmacological treatments appear to be more beneficial than nonpharmacological treatments. This article reviews the current literature to assess the epidemiology and diagnosis of hot flashes and the nonpharmacological and pharmacological options for the treatment of hot flashes, in breast cancer patients in particular. When specific treatment options have not been evaluated in breast cancer patients specifically, published data on the management of hot flashes with this modality in healthy postmenopausal women are described.
