Is surgical management compromised in elderly patients with breast cancer?

Metastasis patterns and prognosis of octogenarians with metastatic breast cancer: A large-cohort retrospective study

Background

Breast cancer may differ biologically in patients aged over 80 years. The objective of the current study was to analyze the metastasis patterns and prognosis of elderly patients with metastatic breast cancer (MBC) and compare it to patients of other ages.

Methods

The Surveillance, Epidemiology, and End Results (SEER) database was utilized to select MBC patients from 2010 to 2015. Chi-squared test was used to compare clinicopathological characteristics among different aged groups. The Kaplan-Meier method and multivariate Cox model were utilized for survival analysis.

Results

A total of 10479 MBC patients were included, among which 1036 (9.9%) patients were aged over 80 years. Compared with other aged group, the elderly patients tended to have a higher proportion of HR+/Her2- subtype, white race, lower tumor differentiation, and receive less treatment, including surgery, chemotherapy and radiotherapy (P< 0.001). MBC patients with different age presented with distinctive metastatic patterns. The older patients were more likely to have lung metastasis, but less likely to have bone, brain, liver and multiple sites metastasis than the younger group (P <0.001). The proportion of TNBC subtype increased substantially in the older patients with brain metastasis, compared to the younger and middle-aged group. The old age was demonstrated to significantly associate with worse prognosis of MBC patients. Additionally, our findings also showed that older MBC patients could achieve dramatical overall survival benefit from surgery (HR = 0.58; P <0.001) and chemotherapy (HR = 0.59; P <0.001), but not the radiotherapy (HR = 0.96; P = 0.097).

Conclusion

The elderly MBC patients presented with distinctive metastatic patterns, clinical characteristics, and prognostic outcomes compared with younger patients. Our findings could assist clinicians in making appropriate therapeutic decision.

A worse ECOG-PS is associated with 30-day mortality among patients over 90 years old in non-cardiac surgeries: A single-center retrospective study

BACKGROUND

A growing number of older patients are undergoing surgeries. The reliable pre-operative predictive factors of surgical mortality among older patients remained unclear. This study compared the predictive factors for 30-day survival in patients over 90 years old after their non-cardiac surgery.

METHODS

A retrospective study at Nippon Medical School hospital was performed for patients aged >90 years who underwent non-cardiac surgeries between 2010 and 2020. Measurements included age, gender, American Society of Anesthesiologists physical status (ASA-PS), pre-operative Charlson score, pre-operative fall risk assessment, Eastern Cooperative Oncology Group performance status (ECOG-PS), the modified 5-item frailty index (mFI-5), the presence of intra-operative transfusion, post-operative complications, and 30-day survival post-surgery.

RESULTS

A total of 327 cases of elective surgery and 149 cases of emergency surgery were examined. The non-survival group (n=20, 4.2%) had significantly worse pre-operative ASA-PS in emergency cases (non-survival vs. survivor group, 2.8 [2-3] vs. 2.3 [1-4], p=0.045), ECOG-PS (3.0 [2-4] vs. 1.0 [0-4], p<0.001), and mFI-5 values (3.0 [1-4] vs. 1.0 [0-3], p<0.001), more emergency cases (75.0% vs. 36.2%, p=0.004), and a greater need for intra-operative transfusion (55.0% vs. 13.4%, p<0.001). Among the frailty assessment methods, ECOG-PS was the most efficient for 30-day mortality (area under curve, ECOG-PS: 0.98, p<0.001; mFI-5: 0.86, p<0.001; Charlson score: 0.53, p=0.71; fall risk assessment: 0.55, p=0.44). Kaplan-Maier curves and a multivariate logistic regression analysis demonstrated that ECOG-PS>3 was significantly associated with 30-day mortality (ECOG-PS: Kaplan-Maier curve, p<0.001, Log-rank test; odds ratio 1.71, 95%CI: 1.35-2.16, p<0.001).

CONCLUSIONS

After non-cardiac surgery in patients >90 years old, ECOG-PS>3 was significantly correlated with 30-day mortality.

Survival Outcomes of Early-Stage Hormone Receptor-Positive Breast Cancer in Elderly Women

BACKGROUND

Elderly women (≥ 70 years old) form a significant proportion of patients affected by breast cancer (BC); however, the treatment decisions for this patient population are complicated, owing to the presence of comorbidities, limited life expectancy, reduced tolerability of therapy, and limited enrollment in clinical trials. A growing body of evidence suggests equivalent outcomes in elderly patients with hormone receptor-positive early-stage breast cancer receiving primary endocrine therapy only or surgery with subsequent endocrine therapy. Whether these results are reproduced in the larger BC population outside of a clinical trial currently remains unclear.

PATIENTS AND METHODS

Women ≥ 70 years old diagnosed with early-stage invasive breast cancer between January 2008 and December 2013 with tumor size T1 or T2, minimal nodal involvement (N0 and N1), and estrogen and/or progesterone receptor positivity who started endocrine therapy within a year of diagnosis were identified using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked datasets. Endocrine therapy was identified using outpatient prescription fills for anastrozole, exemestane, fulvestrant, letrozole, raloxifene, tamoxifen, and toremifene; the first fill date was used as the treatment initiation date. Surgical intervention included either breast-conserving surgery or mastectomy. Women who received chemotherapy were excluded. Trends in the use of primary endocrine therapy only were assessed using Poisson regression. Multivariable Cox proportional hazard regression was used to estimate the association between undergoing surgery within a year of diagnosis and 5-year all-cause mortality, after adjusting for patient demographics, comorbidities, and clinical cancer characteristics. Similar methods were used to assess 5-year cancer-specific mortality, where noncancer mortality was treated as a competing risk.

RESULTS

Overall, 8784 women were included in the analysis: 8006 (91%) received surgery with endocrine therapy and 778 (9%) received primary endocrine therapy alone. The proportion of women not receiving surgery remained consistent between 2008 and 2013 (p = 0.10). The 5-year mortality was 11% (n = 619), and 19% of all deaths were due to cancer causes (n = 117). After adjustment, 5-year mortality was lower among women undergoing surgery (HR 0.59, 95% CI 0.47-0.74, p < 0.0001). Similar results were found when looking at 5-year cancer-specific mortality (HR 0.52, 95% CI 0.30-0.90, p < 0.0001).

CONCLUSIONS

Elderly breast cancer patients with early-stage hormone-receptor-positive disease receiving primary surgical intervention plus endocrine therapy may have significantly improved survival than those receiving primary endocrine therapy alone. This study suggests the importance of surgical intervention for elderly breast cancer patients and warrants further investigation and comprehensive geriatric assessment to identify subsets of elderly breast cancer patients who may benefit significantly from surgical intervention.

Treatment Practices and Outcomes of Elderly Women with Breast Cancer in a Community Hospital

There is a paucity of clinical data available on specific treatment in the oncogeriatric population with breast cancer. The purpose of this study was to evaluate treatment patterns and survival outcomes in the elderly to address any disparities at our community hospital. We retrospectively identified a total of 1749 patients diagnosed and treated for breast cancer at our institution between 2001 and 2011. Patient demographics, surgical treatment, stage of disease, tumor characteristics, adjuvant therapy, and 5-year survival data were obtained from tumor registry records. Comparisons between study groups were made using the Pearson χ2 test and Student's t test. We found more favorable prognostic makers among women older than 70 years of age. Of the women with lymph node-positive disease, 84 per cent of those younger than 70 years and 33 per cent in the older than 70 years of age study group received chemotherapy. Adjuvant chemotherapy and radiation therapy were more frequently performed in the younger group. Overall 5-year survival was 90 per cent and 71 per cent for younger than 70 years and older than 70 years groups, respectively. Women older than 70 years of age have more favorable breast cancer characteristics compared with younger women and received less aggressive treatment and experienced a higher mortality rate. Prospective trials are needed to assess the impact of aggressive multimodality therapy in this oncogeriatric population.

Locally Advanced Breast Cancer in the Elderly: Curettage Mastectomy

Aims and background

Locally advanced breast tumor represents 5–20% of new cases diagnosed every year. The purpose of this study was to report our experience and to compare it with the literature.

Methods

From 1998 to 2003 at the Molinette Hospital in the Turin University Third Division of General Surgery, there were 34 cases of breast cancer in older women (between 70 and 94 years of age), 14 of which (41.18%) were locally advanced breast tumor. We evaluated the type of surgical intervention and anesthesia used, muscular invasion, the presence of receptors positive to estrogens and progesterone, the operative mortality, the percentage of local-regional recurrence, and relapses after a period of time.

Results

Among the patients with locally advanced breast tumor, 21.43% (3/14) were at stage MIA and 78.57% (11/14) at stage IIIB. In 14.29% (2/14) of the cases, Patey's radical mastectomy was performed, in 57.14% (8/14) Halsted's radical mastectomy, and in 28.57% (4/14) a simple mastectomy with the removal of the fascia of the major pectoral muscle. Three (21.43%) patients underwent a second intervention for local-regional disease. None of the patients had distant metastasis in the first 2 years after the operation. Mortality after 2 years was 23.1% (3/13). None of the patients who underwent surgery had adjuvant therapy, usually because it was refused by the patients themselves or their families. All the negative and positive hormone receptor patients received tamoxifen.

Conclusions

Locally advanced breast tumors are frequent in elderly women. In the past, there has been a tendency to surgical under-treatment. As regards locally advanced breast tumor, curettage operations represent the only possibility to improve the quality of life of the elderly. These should be performed after carefully evaluating a series of variables in the general and local condition of the patient, the aggressiveness of the intervention and the life expectancy.

Breast diseases in women over the age of 65 in Monastir, Tunisia

As life expectancy is on the rise, it is predicted that a growing number of people will live beyond the age of 65 and therefore a higher number of elderly women will have breast diseases requiring significant health care and services. This study is aimed at investigating the characteristics, the treatment and outcomes of women older than 65 years old treated for breast diseases at our institution. This was a retrospective study covering the period from January 2003 to December 2011. It involved 92 patients aged over 65 and treated for breast disease in the Maternity Center of Monastir, Tunisia. The data included characteristics of patients and tumors, treatment and outcomes that were obtained through data extraction sheets. We reported a study of 92 women over the age of 65 of whom 77 women had malignant breast disease (83.6%) and 15 benign breast diseases (16.4%). Breast cancer was discovered at a mean age of 72.5 ± 6.6 years. Distant metastases were found in 5.3% of cases and infiltrative ductal carcinoma was detected in 85.7% of patients. Hormonal receptors were positive for estrogens in 64.7% of cases. Surgical treatment was performed in 73 patients and adjuvant treatment was prescribed for 67 women (86%). The complication rate was 16.6% among the 73 patients who underwent surgery. Benign breast diseases represented 16.3% of the mammary pathologies. Abscesses and fibrocystic mastopathy were the most frequent histological diagnoses. Despite great interest in geriatric gynecological pathology worldwide, many questions related to how optimally treat this patient population remain unanswered. In this study, a surgical treatment was performed in 94.8% of breast cancer patients and the complication rate was 16.6%.

Locally Advanced Breast Cancer in the Elderly: A Major Challenge Requiring Effective and Appropriate Treatment

Aims and background

Breast cancer is the most common tumor in women. As the population above 65 years increases, breast cancer will be a more substantial problem for elderly patients. This work reports our experience in the management of stage III and IV locally advanced breast cancer.

Methods

Nineteen patients over 65 years of age (mean, 70.3 years) with stage III and IV breast cancers, treated between 1990 and 2000, are considered. The management and outcome are evaluated.

Results

Nine patients had stage IIIA breast cancer, 7 stage IIIB and 3 stage IV. Sixteen underwent Madden mastectomy and 3 simple mastectomy. Patients at stage HIB and 1 patient at stage IV with T4 tumor received neo-adjuvant chemotherapy. There were no significant postoperative complications. Sixteen patients were given tamoxifen and 10 patients adjuvant chemotherapy. Patients were followed for a median of 36.7 months (range, 6–72 months). In 8 patients with stage III disease, metastasis developed. Two patients had local recurrence of disease. Of the patients at stage IIIA, 6 were free from disease (one died from unrelated causes) and 3 had recurrent disease (2 died). Of the patients at stage IIIB, 2 are disease free and 5 had recurrent disease and died. Of the patients at stage IV, only one is alive.

Conclusions

Stage and individual characteristics of elderly women influence management. Patients should be managed adequately since most of them are fit enough to undergo treatment.

Ageism and surgical treatment of breast cancer in Italian hospitals

AIM

To determine if age is a factor influencing the type of breast cancer surgery (radical versus conservative) in Italy and to investigate the regional differences in breast cancer surgery clinical practice.

METHODS

Retrospective study is based on national hospital discharge records. The study draws on routinely collected data from hospital discharge records in Italy in 2010. The following exclusion criteria were applied: day hospital stays, patients younger than 17 years, males, patients without an ICD-9CM code indicating breast cancer and breast surgery, and repeated hospital admission of the same patient. Overall, 49,058 patient records were selected for the analysis.

RESULTS

The proportion of conservative breast cancer operations was 70.9%. A greater number of women younger than 70 had undergone a breast-conserving operation compared to older women. There were regional variations ranging from a minimum in Basilicata to a maximum in Val d'Aosta. Multivariate analysis revealed that older patients with lower clinical severity were more likely to have undergone a radical operation than younger women. In addition, radical surgery was approximately twice as likely to occur in a private hospital that performed at least 50 breast cancer operations annually than in a public hospital that performed <50 breast surgeries.

CONCLUSION

Notwithstanding increases in life expectancy and the lack of clinical evidence to support the use of age as a surrogate for co-morbid conditions and frailty, our data on breast cancer operations in Italy are consistent with the hypothesis suggesting the persistence of ageistic practice in the healthcare system.

Early-Stage Breast Cancer in the Octogenarian: Tumor Characteristics, Treatment Choices, and Clinical Outcomes

BACKGROUND

Nodal staging with sentinel node biopsy (SLNB), post-lumpectomy radiotherapy (RT), and endocrine therapy (ET) for estrogen receptor-positive (ER+) tumors is valuable in the treatment of early-stage (stages 1 or 2) breast cancer but used less often for elderly women.

METHODS

This retrospective study investigated women referred for surgical evaluation of biopsy-proven primary early-stage invasive breast cancer from January 2001 to December 2010. Clinicopathologic features, treatment course, and outcomes for women ages 80-89 years and 50-59 years were compared.

RESULTS

The study identified 178 eligible women ages 80-89 years and 169 women ages 50-59 years. The elderly women more often had grade 1 or 2 disease (p = 0.003) and ER+ tumors (p = 0.007) and less frequently had undergone adjuvant therapies (all p ≤ 0.001). Lumpectomy was performed more commonly for the elderly (92 vs. 83 %, p = 0.02), and axillary surgery was less commonly performed (46 vs. 96 %; p < 0.001). Fewer elderly women had undergone post-lumpectomy RT (42 vs. 89 %; p < 0.001) and ET for ER+ tumors (72 vs. 95 %; p < 0.001). During the median follow-up period of 56 months for the 80- to 89-year old group and 98 months for the 50- to 59-year-old group, death from breast cancer was similar (4 vs. 5 %; p = 0.5). The two groups respectively experienced 7 versus 6 locoregional recurrences and 11 versus 13 distant recurrences.

CONCLUSIONS

The octogenarians had disease survivorship similar to that of the younger women despite less frequent use of adjuvant therapies, likely reflecting lower-risk disease features. Whether increased use of axillary surgery, post-lumpectomy RT, and/or ET for ER+ tumors would further improve outcomes is an important area for further study, but treatment should not be deferred solely on the basis of age.

Two decades of axillary management in breast cancer

Background

Axillary lymph node dissection (ALND) in patients with breast cancer provides prognostic information. For many years, positive nodes were the most important indication for adjuvant systemic therapy. It was also believed that regional control could not be achieved without axillary clearance in a positive axilla. However, during the past 20 years the treatment and staging of the axilla has undergone many changes. This large population-based study was conducted in the south-east of the Netherlands to evaluate the changing patterns of care regarding the axilla, including the introduction of sentinel lymph node biopsy (SLNB) in the late 1990s, implementation of the results of the American College of Surgeons Oncology Group Z0011 study, and the initial effects of the European Organization for Research and Treatment of Cancer AMAROS study.

Methods

Data from the population-based Eindhoven Cancer Registry of all women diagnosed with invasive breast cancer in the south of the Netherlands between January 1993 and July 2014 were used.

Results

The proportion of 34 037 women staged by SLNB without completion ALND increased from 0 per cent in 1993–1994 to 69·0 per cent in 2013–2014. In the same period the proportion undergoing ALND decreased from 88·8 to 18·7 per cent. Among women with one to three positive lymph nodes, the proportion undergoing SLNB alone increased from 10·6 per cent in 2011–2012 to 37·6 per cent in 2013–2014.

Conclusion

This population-based study demonstrated the radical transformation in management of the axilla since the introduction of SLNB and following the recent publication of trials on management of the axilla with a low metastatic burden.

Distinct postsurgical management in young and elderly breast cancer patients results in equal survival rates

BACKGROUND

Although breast cancer (BC) is one of the most common malignant diseases in women, the majority of the studies describing the characteristics of BC in elderly patients have been limited to survival assessments or tumor features, without using younger BC patients as a reference group. The aim of our study was to describe and compare tumor characteristics and management patterns in elderly versus younger breast cancer patients in Turkey.

MATERIALS AND METHODS

We retrospectively analyzed 152 patients with invasive breast cancer who underwent surgery in our institution between 2002 and 2012. Patients were divided into 2 groups according to age at the time of diagnosis.

RESULTS

There were 62 patients in the elderly group (≥65 years) and 90 patients in the younger group (<65 years). Compared to the younger group, tumors in the elderly group were more likely to be larger (p=0.018), of lower grade (p=0.005), and hormone receptor-positive (p>0.001). There were no significant differences regarding histology, localization, lymph node involvement, or types of surgical procedures between the 2 groups. Comorbidities were more common in elderly patients (p<0.001). In addition, elderly patients were more likely to receive hormonal therapy (p<0.001) and less likely to receive radiotherapy (p=0.08) and chemotherapy (p=0.003). There was no difference in survival and locoregional recurrence rates between the groups.

CONCLUSIONS

The results of this study demonstrate that breast cancer in elderly patients has more favorable tumor features, warranting less aggressive treatment regimens after surgery.

Deviation from the Standard of Care for Early Breast Cancer in the Elderly: What are the Consequences?

BACKGROUND

For elderly patients with early-stage breast cancer, the standards of care often are not strictly followed due to either clinician biases or patient preferences. The authors hypothesized that forgoing radiation and lymph node (LN) staging for elderly patients with early-stage breast cancer would have a negative impact on survival.

METHODS

From the Surveillance, Epidemiology, and End Results Program database, 53,619 women older than 55 years with stage 1 breast cancer who underwent breast conservation surgery were identified. Analyses were performed to compare the characteristics and outcomes of patients who received the standards of care with LN sampling and radiation and those of patients who did not, with control used for confounders. To account for selection bias from covariate imbalance, propensity score matching was performed. Survival was analyzed using the Kaplan-Meier method.

RESULTS

Older patients were less likely to receive radiation and LN sampling. These standards of care were associated with improved overall survival rates of 15.8 and 27.1 % after 10 years, respectively (p ≤ 0.0001). This survival advantage persisted after propensity score matching, with a 7.4 % higher survival rate for patients who received radiation and a 16.8 % higher survival rate for those who underwent LN staging (p < 0.0001). Lymph node sampling and radiation therapy also conferred a statistically significant improvement in breast cancer-specific survival, with 1.3 and 2.6 % lower mortality rates respectively in the radiated and LN biopsy groups (p < 0.0001).

CONCLUSIONS

As patients age, they are less likely to receive the standard of care for stage 1 breast cancer. Even after controlling for other factors, the study showed that failure to adhere to the standards of LN sampling and radiation therapy may have a negative impact in survival.

Preoperative assessment of the older surgical patient: honing in on geriatric syndromes

Nearly 50% of Americans will have an operation after the age of 65 years. Traditional preoperative anesthesia consultations capture only some of the information needed to identify older patients (defined as ≥65 years of age) undergoing elective surgery who are at increased risk for postoperative complications, prolonged hospital stays, and delayed or hampered functional recovery. As a catalyst to this review, we compared traditional risk scores (eg, cardiac-focused) to geriatric-specific risk measures from two older female patients seen in our preoperative clinic who were scheduled for elective, robotic-assisted hysterectomies. Despite having a lower cardiac risk index and Charlson comorbidity score, the younger of the two patients presented with more subtle negative geriatric-specific risk predictors – including intermediate or pre-frail status, borderline malnutrition, and reduced functional/mobility – which may have contributed to her 1-day-longer length of stay and need for readmission. Adequate screening of physiologic and cognitive reserves in older patients scheduled for surgery could identify at-risk, vulnerable elders and enable proactive perioperative management strategies (eg, strength, balance, and mobility prehabilitation) to reduce adverse postoperative outcomes and readmissions. Here, we describe our initial two cases and review the stress response to surgery and the impact of advanced age on this response as well as preoperative geriatric assessments, including frailty, nutrition, physical function, cognition, and mood state tests that may better predict postoperative outcomes in older adults. A brief overview of the literature on anesthetic techniques that may influence geriatric-related syndromes is also presented.

Research in cancer care disparities in countries with universal healthcare: mapping the field and its conceptual contours

The paper reviews published studies focused on disparities in receipt of cancer treatments and supportive care services in countries where cancer care is free at the point of access. We map these studies in terms of the equity stratifiers they examined, the countries in which they took place, and the care settings and cancer populations they investigated. Based on this map, we reflect on patterns of scholarly attention to equity and disparity in cancer care. We then consider conceptual challenges and opportunities in the field, including how treatment disparities are defined, how equity stratifiers are defined and conceptualized and how disparities are explained, with special attention to the challenge of psychosocial explanations.

Surgery versus primary endocrine therapy for operable primary breast cancer in elderly women (70 years plus)

BACKGROUND

Several studies have evaluated the clinical effectiveness of endocrine therapy alone in women aged 70 years or over with operable breast cancer and who are fit for surgery.

OBJECTIVES

To systematically review the evidence for the clinical effectiveness of surgery (with or without adjuvant endocrine therapy) in comparison to primary endocrine therapy in the treatment of operable breast cancer in women aged 70 years and over, both in terms of local progression and mortality.

SEARCH METHODS

We conducted an updated search of the Cochrane Breast Cancer Group's Specialised Register (27th March 2013) and new searches of the Cochrane Central Register of Controlled Trials (CENTRAL, 2013, Issue 3), MEDLINE, EMBASE, the World Health Organization's International Clinical Trials Registry Platform (apps.who.int/trialsearch/) and www.

CLINICALTRIALS

gov, using the search terms 'early breast cancer', 'endocrine therapy', 'psychosocial' or 'surgery'.

SELECTION CRITERIA

Randomised trials comparing surgery, with or without adjuvant endocrine therapy, to primary endocrine therapy in the management of women aged 70 years or over with early breast cancer and who were fit for surgery.

DATA COLLECTION AND ANALYSIS

We assessed studies for eligibility and quality, and two review authors independently extracted data from published trials. We derived hazard ratios for time-to-event outcomes, where possible, and used a fixed-effect model for meta-analysis. We extracted toxicity and quality-of-life data, where present. Where outcome data were not available, we contacted trialists and requested unpublished data.

MAIN RESULTS

We identified seven eligible trials, of which six had published time-to-event data and one was published only in abstract form with no usable data. The quality of the allocation concealment was adequate in three studies and unclear in the remainder. In each case the endocrine therapy used was tamoxifen. Data, based on an estimated 1081 deaths in 1571 women, did not show a statistically significant difference in favour of either surgery or primary endocrine therapy in respect of overall survival. However, there was a statistically significant difference in terms of progression-free survival, which favoured surgery with (474 participants) or without endocrine therapy (164 participants). The hazard ratios (HRs) for overall survival were: HR 0.98 (95% confidence interval (CI) 0.81 to 1.20, P = 0.85; 3 trials, 495 participants) for surgery alone versus primary endocrine therapy; HR 0.86 (95% CI 0.73 to 1.00, P = 0.06; 3 trials, 1076 participants) for surgery plus endocrine therapy versus primary endocrine therapy. The HRs for progression-free survival were: HR 0.55 (95% CI 0.39 to 0.77, P = 0.0006) for surgery alone versus primary endocrine therapy; HR 0.65 (95% CI 0.53 to 0.81, P = 0.0001) for surgery plus endocrine therapy versus primary endocrine therapy (each comparison based on only one trial). Tamoxifen-related adverse effects included hot flushes, skin rash, vaginal discharge, indigestion, breast pain, sleepiness, headache, vertigo, itching, hair loss, cystitis, acute thrombophlebitis, nausea, and indigestion. Surgery-related adverse effects included paraesthesia on the ipsilateral arm and lateral thoracic wall in those who had axillary clearance. One study suggested that those undergoing surgery suffered more psychosocial morbidity at three months post-surgery, although this difference had disappeared by two years.

AUTHORS' CONCLUSIONS

Primary endocrine therapy should only be offered to women with oestrogen receptor (ER)-positive tumours who are unfit for surgery, at increased risk of serious surgical or anaesthetic complications if subjected to surgery, or who refuse surgery. In a cohort of women with significant co-morbid disease and ER-positive tumours it is possible that primary endocrine therapy may be a superior option to surgery. Trials are needed to evaluate the clinical effectiveness of aromatase inhibitors as primary therapy for an infirm older population with ER-positive tumours.

Primary endocrine therapy as a treatment for older women with operable breast cancer - a comparison of randomised controlled trial and cohort study findings

INTRODUCTION

One third of all breast cancers occur in women over the age of 70. Primary endocrine therapy (PET) is used in some women to minimise morbidity in a population with higher rates of comorbidity and frailty. In the UK up to 40% of women over 70 are treated with PET although there is a high rate of variability of practice between centres reflecting a lack of guidance about case selection.

METHODS

A systematic review of the literature was performed to try and establish if this form of treatment is still valid in modern breast practice.

RESULTS

Six randomised controlled trials (RCTs) and 31 non-randomised studies were deemed eligible. Available data demonstrate an advantage for surgery over PET in terms of disease control and a likely survival benefit in patients with a predicted life expectancy of five years or more. Patients treated only with aromatase inhibitors (AIs) had superior rates of disease control when compared to Tamoxifen.

CONCLUSIONS

Guidelines to aid selection are needed but PET should be reserved for patients with reduced predicted life expectancy (e.g. less than five years), with AIs being preferable over Tamoxifen.

Undertreatment of breast cancer in the elderly

Aims

The effect of undertreatment with adjuvant hormonal therapy, chemotherapy or radiation was studied in elderly women with breast cancer.

Methods

A prospectively maintained database was used to identify women undergoing potentially curative surgery between 1997 and 2011. The presentation, pathologic findings, treatment and outcomes of 449 women over 65 were compared to the findings in 1049 younger patients. Moreover, conventionally treated and undertreated elderly patients were identified and their characteristics and outcomes were compared.

Results

Both young and old patients presented most frequently with mammographic findings, but older patients presented more frequently with mammographic masses while younger patients presented more frequently with mammographic calcifications. Cancers of older patients were signicantly more favorable than cancers in younger patients with more infiltrating lobular, fewer ductal carcinoma in situ and more frequently estrogen receptor positive and fewer were poorly differentiated. Elderly patients had less axillary surgery, less adjuvant radiation therapy and more hormonal therapy. Fourty-six percent of the 449 elderly patients were undertreated by conventional criteria. Undertreated patients were more frequently in situ, better differentiated, smaller, and more often estrogen receptor positive. Forty-four percent of the undertreated patients died during follow-up without disease recurrence.

Conclusions

Despite undertreatment, local and distant disease-free survival was comparable to patients who were not undertreated.

Undertreated breast cancer in the elderly

The effect of undertreatment with adjuvant hormonal therapy, chemotherapy, or radiation was studied in elderly women with breast cancer. A prospectively maintained database was used to identify women undergoing potentially curative surgery between 1978 and 2012. The presentation, pathologic findings, treatment, and outcomes of 382 women over 70 were compared to the findings in 2065 younger patients. Subsequently, conventionally treated and undertreated elderly patients were identified and their characteristics and outcomes were compared. Both young and old patients presented most frequently with mammographic findings, but older patients presented more frequently with mammographic masses while younger patients presented more frequently with mammographic calcifications. Cancers of older patients were significantly more favorable than cancers in younger patients: smaller, with more infiltrating lobular, fewer ductal carcinoma in situ, and more frequently estrogen receptor positive and fewer were poorly differentiated. Elderly patients had less axillary sampling, fewer mastectomies, less adjuvant radiation therapy, and more hormonal therapy. Fifty-one percent of the 382 elderly patients were undertreated by conventional criteria. Undertreated patients were more frequently in situ, better differentiated, smaller, and more often estrogen receptor positive. Forty-four percent of the undertreated patients died during followup without disease recurrence. Despite undertreatment, local and distant disease-free survival was comparable to patients who were not undertreated.

Differences in outcomes between elderly and nonelderly breast cancer patients in Louisiana

INTRODUCTION

Elderly breast cancer patients are diagnosed with a higher stage of disease. They are also found to undergo less surgery, receive more frequently hormonal treatment and have decreased relative survival. The interest of this study was to examine the differences in treatment and survival between elderly versus young (>65 versus <65) patients in Louisiana.

METHODS

The SEER database was searched, and all cases of female breast cancer in the state of Louisiana between 2000 and 2008 were analyzed. Data were stratified by age group and year of occurrence. The SEER definitions for breast cancer, surgery, chemotherapy, elderly populations, young populations, radiation therapy and breast conservative surgery were applied.

RESULTS

The state prevalence of localized breast cancer is lower compared with the national rate (128.5 versus 144, P < 0.001). The rate of regional breast disease is much higher in Louisiana patients than national average rate (69.7 versus 57.9, P < 0.001). There is no difference in disseminated disease. The elderly group was offered less surgery compared with the young group (11.39% versus 6.68%, P < 0.005). The elderly group received more general radiation interventions than the young group (65.97% versus 53.86%, P < 0.005). Mortality rates for the elderly group were higher in Louisiana compared with the national average. This difference was more remarkable in the >85 age group (127.8 versus 118.5, P < 0.001).

CONCLUSIONS

Differences between young and elderly breast cancer patients were observed. Mortality is higher among elderly breast cancer patients in Louisiana compared with the national average. Further studies are needed to review these differences.

Breast cancer treatment practices in elderly women in a community hospital

Background. Elderly women with breast cancer are considered underdiagnosed and undertreated, and this adversely affects their overall survival. Methods. A total of 393 female breast cancer patients aged 70 years and older, diagnosed within the years 1989-1999, were identified from the tumor registry of The Brooklyn Hospital Center. Comparisons between the 3 different subgroups 70-74, 75-79, and 80 years and older were made using the Pearson Chi Square test. Results. Lumpectomy was performed in 42% of all patients, while mastectomy was done in 46% of patients. Adjuvant therapy such as chemotherapy, radiation therapy, and hormonal therapy were done in 12%, 25%, and 38%, respectively. Forty-seven percent of patients with positive lymph nodes received chemotherapy. Eighty-six percent of patients who were estrogen receptor-positive received adjuvant hormonal therapy. Overall five-year survival was only 14% for the ≥80 age group, compared to that of 32% and 35% for the 70-74 and the 75-79 age groups, respectively. Conclusions. Surgery was performed in majority of these patients, about half received lumpectomy, the other half mastectomy. Adjuvant therapies were frequently excluded, with only hormonal therapy being the most commonly used. Overall five-year survival is significantly worse in patients ≥80 years with breast cancer.

Effect of patient age on airway response by paramedics: frailty or futility?

OBJECTIVE

We studied patterns related to patient age and indication for airway interventions delivered by paramedics from 2000 through 2004.

METHODS

The study population included patients ≥ 15 years old managed by paramedics. Outcomes were the frequencies of definitive airway, ventilatory techniques, and oxygenation techniques. Independent variables were patient age, gender, race, hospital drive time, do-not-resuscitate status, and two trauma indicators of the American College of Surgeons Committee on Trauma (anatomic injury and mechanism of injury). Subset analysis was performed with the presence or absence of a set of recorded conditions.

RESULTS

A total of 827,772 paramedic transports were studied; 233,470 were identified with at least one indication for airway intervention. Patients older than 65 years were, when compared with patients 65 years old or younger, 1) less likely to receive ventilatory interventions with any indication; 2) more likely to receive ventilatory intervention without an indication; and 3) more likely to receive oxygenation interventions whether indications were present or not. We considered age in five-year intervals and noted a consistent biphasic pattern for all interventions, regardless of indications. The odds ratios for interventions for patients in each block compared with those for 15- to 29-year-old patients increased with age until about 70 years of age, then gradually declined.

CONCLUSIONS

Patterns of age-related variations in airway interventions cannot be explained by the application of protocols. The reason for the peak rate of interventions at age 70 years is unknown. Explanations need to consider the influence on paramedic behavior of a number of factors, including frailty and futility. Additional paramedic training may be needed to change these patterns.

Determinants of outcome in elderly patients with positive sentinel lymph nodes

BACKGROUND

Older women are less likely to receive standard of care treatment for breast cancer.

METHODS

We examined variables that affected the outcome of elderly patients ≥70 years old among 1,470 patients with invasive cancer with positive sentinel lymph nodes (SLNs).

RESULTS

Elderly patients were less likely to undergo mastectomy, completion axillary node dissection (ALND), adjuvant chemotherapy, and radiotherapy (RT) following breast-conserving therapy (BCT) compared with patients <70 years old. The 5-year risk of disease progression and cumulative incidence of breast cancer-specific deaths were not significantly different for both groups. On multivariate analysis, hormone receptor-negative status, number of metastatic lymph nodes, high nuclear grade, and tumor size were the factors independently associated with increased risk of disease progression.

CONCLUSIONS

Tumor factors were the primary determinants of breast cancer outcomes in our cohort. Elderly patients are less likely to receive aggressive surgical interventions and adjuvant therapy because of perceived life expectancy.

Breast cancer in the elderly: retrospective study on diagnosis and treatment according to national guidelines

We set out to investigate the level of accordance of diagnosis and treatment of elderly breast cancer patients with national guidelines and to study predictors of deviation. Data on patient and tumor variables were collected from charts of 166 patients aged 70 years and older, diagnosed at our hospital in 2002-2004. Diagnostic work-up and treatment were compared with guidelines and reasons for deviation were recorded; 122 (74%) patients were diagnosed and treated in accordance with guidelines. Diagnosis was incomplete in 19 patients (11%). Surgery, radiotherapy, and hormonal therapy were withheld in 19 (11%), 11 (7%), and 9 (5%) patients, respectively. Guideline deviation was motivated in 18 patients (11%) (comorbidity n=11, patients' preferences n=5, age n=2), unmotivated in 18 (11%), and undeliberate in 8 (5%). Our study demonstrates that deviation from guidelines in elderly breast cancer patients mainly occurs due to a deliberate adjustment to patient's comorbidity and preference.

Treatment decision making and its discontents

Patient participation in treatment decision making is held as a virtue in clinical contexts, and has much to recommend it. Yet important questions have been raised about the assumptions underlying models of patient participation. Debates have arisen about the significance of medically defined risks and outcomes of treatment; the adequacy and relevance across social groups of the concept of autonomy; and the emphasis on the professional-patient dyad. This article contributes to the debate about treatment decision making with reference to a study focused on older women with cancer. Interviews with patients and cancer care professionals highlighted the salience to patients' treatment choices of experiential knowledge, social roles and responsibilities, and the health policy context. It appears that prevailing models of decision making may obscure patients' more typical decision processes as well as the social determinants of those choices.

Treatment of breast cancer in older women

BACKGROUND

Breast carcinoma management in the elderly often differs from the management in younger women and there is considerable controversy about what constitutes appropriate cancer care for older women. This controversy is reflected in the persistence of age-dependent variations in care over time, with older women being less likely to receive definitive care for breast cancer. There has been a significant increase in the last years in the number of studies conducted in older patients with breast cancer. Although available age-specific clinical trials data demonstrate that treatment efficacy is not modified by age, this evidence is limited by the lack of inclusion of substantial numbers of older women, particularly those of advanced age and those with comorbidities.

METHOD

The literature-based evidence of the last 10 years was extensively reviewed on the main issues concerning the treatment of breast cancer in older women.

RESULTS

Surgical treatment in older patients has evolved from avoidance to mastectomy to breast-conserving surgery, similarly to younger patients. Given its negative effect on the quality of life, in the last few years the role of adjuvant radiotherapy has been questioned in elderly patients with breast cancer. Adjuvant chemotherapy benefit in older patients applies mainly to Estrogen-receptor-negative patients, while in Estrogen-receptor-positive patients a major role is played by endocrine treatment. New "elderly-friendly" drugs, that can help clinicians to reduce toxicity, are now available for breast cancer.

Assessment of Surgical Treatment in Elderly Patients with Breast Cancer

Aims and Background

The incidence of breast cancer increases with advancing age and in clinical practice approximately 50% of new cases occur in women over the age of 65 years. Although breast cancer in elderly patients presents more favorable biological characteristics than similar-stage cancer in younger women, disease control still remains uncertain and is becoming a major health problem.

Patients and Methods

Between 1984 and 2006, 133 patients aged over 65 with operable breast cancer underwent surgical treatment. Patients with ductal or lobular carcinoma in situ, bilateral breast cancer or a previous malignancy were excluded. The mean age was 72.8 years (range, 66–89). Breast-conserving surgery was performed in patients with early breast cancer (T1, T2 <2.5 cm), while most patients with advanced tumors (T2 >2.5 cm, T3, T4) were treated by modified radical mastectomy.

Results

The pathological stage was I in 44, IIA in 54, IIB in 18, IIIA in 10 and IIIB in 7 patients. Postoperative complications occurred in 13 patients (9%); there were no postoperative deaths. Eighty-nine patients underwent adjuvant therapy (chemotherapy, hormonal therapy). After a median follow-up of 96 months (range, 5–266), disease progression was observed in 21 patients (15.8%). The overall mortality from breast cancer was 11%, whereas the cancer-unrelated mortality was 9%.

Conclusion

There is no evidence that breast cancer has a more favorable prognosis in the elderly and surgical procedures should be carried out as has been established in younger women. At present, elderly patients are much less likely to be entered into randomized clinical trials and are often undertreated. However, in the absence of serious comorbid disease, they are able to withstand standard multimodal treatment options as well as do younger patients.

Patterns of Surgical Treatment for Women Diagnosed with Early Breast Cancer in Queensland

BACKGROUND

Australian women with early breast cancer should be given the choice between breast-conserving surgery (BCS) or mastectomy. This is the first Australian study to report on patterns of surgical care specifically for early breast cancer at a population level.

METHODS

Two population-based routine data collections were linked to obtain surgical treatment information for breast cancer cases diagnosed in 2004 in Queensland, from which we identified 1274 cases of early female breast cancer. Logistic regression was used to assess the likelihood of female breast cancer patients having mastectomy, BCS, and axillary node dissection, after adjusting for patient and hospital demographics, tumor size, and comorbidities.

RESULTS

Three-quarters (77%) of women had BCS, 29% had a mastectomy, and 86% had dissection of the axillary lymph nodes. The likelihood of women having mastectomy was higher among women living in rural areas, those treated in public hospitals, and women who had comorbidities of anemia or heart failure. In contrast, BCS was more likely for women treated in private hospitals or hospitals with high surgical caseload. Heart failure decreased the likelihood of BCS. Having an axillary node dissection was more likely among younger women and those treated in high caseload hospitals.

CONCLUSION

The observed differentials in surgical treatment for early breast cancer patients suggest that access issues may have contributed to the decision-making process. Understanding the reasons why women with early breast cancer choose a certain treatment strategy should be a focus of future research.

Diagnosing and Treating Breast Cancer in Elderly Women: A Call for Improved Understanding

Breast cancer is the most common nondermatological malignancy in women, and the incidence increases with age until the eighth decade. Breast cancer pathology and biology appear to be different in elderly patients than in younger ones, and therefore treatment recommendations cannot be generalized from one group to the other. Most elderly women can tolerate breast cancer surgery without significant complications and should be offered a definitive surgical procedure. Improved mechanisms to predict which patients will tolerate and benefit from various therapies are under development. Because most breast cancers in the elderly are hormone responsive, hormonal therapy remains the mainstay of systemic treatment in the adjuvant and metastatic settings. Chemotherapy can be used in elderly women, but treatment decisions must be individualized based upon risk-benefit analyses. Elder-specific studies are underway to identify the most-efficacious and best-tolerated therapies for breast cancer in this population. Primary care physicians must be aware of these issues to provide adequate counseling and care to these patients.

Conservative management of breast cancer in the elderly in a developing country

Background

The cost effective treatment of cancer in developing countries remains challenging. In the elderly with possible limited life expectancy, the health expenditure associated with standard treatment regimes should be carefully considered. We present the results of conservative management of breast cancer in the aged in a resource-limited environment.

Methods

Patients aged 70 or older with early breast cancer were treated with tumour excision or simple mastectomy and adjuvant tamoxifen. The records of patients presenting to the Breast Unit between January 1990 and December 2004 were retrieved and demographic, clinical, pathological and oncological data were reviewed. Survival statistics were calculated using the life table method.

Results

A total of 483 patients above 70 years of age were identified. One hundred and eighty eight patients were managed according to the conservative protocol. Forty-one had a simple mastectomy and 147 tumour excision. Their mean age was 77.3 years. The mean follow-up is 62 months. Thirty-one patients (16.4%) were not compliant with tamoxifen use. TNM staging was 0 in 4 patients, I in 42 patients, II in 116 patients and III in 26 patients. There was no 30-day mortality. The cumulative incidence of local recurrence was 3.3% at 5 and 10 years. The cumulative incidence of regional recurrence was 3.3% at 5 years and 4.5% at 10 years. The cumulative incidence of distant recurrence was 6.2% at 5 years and 12.2% at 10 years. The cumulative overall, disease specific and disease free survival at 10 years was 59%, 88% and 81% respectively.

Conclusion

Limited surgery and tamoxifen provide excellent control of breast cancer in the elderly in a resource restricted environment. Radiotherapy and axillary dissection and can be safely omitted thereby reducing health care resource utilization.

Common Gynecologic Problems in Geriatric-aged Women

Gynecologic concerns in postmenopausal women are common. Although various conditions may affect all women in this age group, the prevalence of certain disorders, and also diagnostic approaches and treatment options, may vary significantly when considering very elderly women compared with those early in the sixth decade. The focus of this chapter is to address several commonly encountered gynecologic issues in postmenopausal women, with particular attention given to aspects that must be considered when caring for women in the geriatric age group.

Effectiveness of adjuvant tamoxifen therapy among older women with early stage breast cancer

To investigate the effectiveness of adjuvant tamoxifen in older women with early-stage breast cancer. Between 1997 and 1999, women > or = 65 years old at diagnosis with stage I-IIIa breast cancer were recruited from four geographic regions of the United States and followed prospectively for 5 years after diagnosis. Data sources included tumor registries, medical records review, and telephone interviews. The primary end points were breast cancer-specific and overall survival ascertained by matching identifying data with the National Death Index and Social Security Administration master death file. Tamoxifen prescription was operationalized as tamoxifen prescribed by 6 months after diagnosis. Survival analysis was undertaken using Kaplan-Meier curves and Cox proportional hazards modeling. We studied 689 women whose average age was 74.2 years at diagnosis (SD = 6.3, range 65-96 years). The median follow-up was 67 months (range 3.5-88 months). Of the 689 patients, 519 (76%) were prescribed tamoxifen. The 5-year breast cancer-specific survival was 93% (95% CI = 90-95) and 89% (95% CI = 83-94) for the ever tamoxifen and never tamoxifen groups, respectively. The ratio of adjusted breast cancer mortality hazards was 0.61 (95% CI = 0.31-1.12) for the ever tamoxifen group versus the never tamoxifen group. Similarly, the 5-year overall survival was 81% (95% CI = 76-85) and 70% (95% CI = 61-78) for the ever tamoxifen and never tamoxifen groups, respectively, with an adjusted hazard ratio of 0.53 (95% CI = 0.37-0.77). Adjuvant tamoxifen is associated with improvement in 5-year breast cancer-specific and overall survival in older women with early-stage breast cancer.

Older female cancer patients: importance, causes, and consequences of undertreatment

Despite increased interest in treatment of senior cancer patients, older patients are much too often undertreated. This review aims to present data on treatment practices of older women with breast and gynecologic cancers and on the consequences of undertreatment on patient outcome. We also discuss the reasons and validity of suboptimal care in older patients. Numerous studies have reported suboptimal treatment in older breast and gynecologic cancer patients. Undertreatment displays multiple aspects: from lowered doses of adjuvant chemotherapy to total therapeutic abstention. Undertreatment also concerns palliative care, treatment of pain, and reconstruction. Only few studies have evaluated the consequences of nonstandard approaches on cancer-specific mortality, taking into account other prognostic factors and comorbidities. These studies clearly showed that undertreatment increased disease-specific mortality for breast and ovarian cancers. For other gynecological cancers, data were insufficient to draw conclusions. Objective reasons at the origin of undertreatment were, notably, higher prevalence of comorbidity, lowered life expectancy, absence of data on treatment efficacy in clinical trials, and increased adverse effects of treatment. More subjective reasons were putative lowered benefits of treatment, less aggressive cancers, social marginalization, and physician's beliefs. Undertreatment in older cancer patients is a well-documented phenomenon responsible for preventable cancer deaths. Treatments are still influenced by unclear standards and have to be adapted to the older patient's general health status, but should also offer the best chance of cure.

Surgical risk factors, morbidity, and mortality in elderly patients

BACKGROUND

The aging population of the United States results in increasing numbers of surgical operations on elderly patients. This study observed aging related to morbidity, mortality, and their risk factors in patients undergoing major operations.

STUDY DESIGN

We reviewed our institution's American College of Surgeons National Surgical Quality Improvement Program database from February 24, 2002, through June 30, 2005, including standardized preoperative, intraoperative, and 30-day postoperative data points. This required review and analysis of the prospectively collected data. We examined patient demographics, preoperative risk factors, intraoperative risk factors, and 30-day outcomes with a focus on those aged 80 years and older.

RESULTS

A total of 7,696 surgical procedures incurred a 28% morbidity rate and 2.3% mortality rate, although those older than 80 years of age had a morbidity of 51% and mortality of 7%. Hypertension and dyspnea were the most frequent risk factors in those aged 80 years and older. Preoperative transfusion, emergency operation, and weight loss best predicted morbidity for those 80 years of age and older. Operative duration predicted "other" postoperative occurrences and emergent case status predicted respiratory occurrences across all age groups. Preoperative impairment of activities of daily living, emergency operation, and increased American Society of Anesthesiology classification predicted mortality across all age groups. A 30-minute increment of operative duration increased the odds of mortality by 17% in patients older than 80 years. Postoperative morbidity and mortality increased progressively with increasing age. Age was statistically significantly associated with morbidity (wound, p = 0.021; renal, p = 0.001; cardiovascular, p = 0.0004; respiratory, p < 0.0001) and mortality (p = 0.001).

CONCLUSIONS

Although several risk factors for postoperative morbidity and mortality increase with age, increasing age itself remains an important risk factor for postoperative morbidity and mortality.

Management of early breast cancer in the elderly

Breast cancer is the most common malignancy in women with an age related increase in incidence ranging from 1 in 50 at age 50 to 1 in 10 at age 80. This is particularly significant in view of the changing demographics in the western population, characterised by an aging population and increased life expectancy. However in spite of favourable prognostic factors and less aggressive biological behaviour, elderly breast cancer patients receive less aggressive treatment when compared with their younger counterparts. Appropriate treatment should be offered depending on physiological reserve and comorbidities. Primary endocrine treatment has been shown to be associated with significant morbidity in terms of disease progression. Prompt surgery and adjuvant treatment can decrease relapse and improve survival. Radiation therapy is shown to decrease local relapse and chemotherapy may have a role in a select group of patients with adverse prognostic factors. With incidence of breast cancer bound to increase in the elderly population, it is essential to establish optimum therapy in this cohort of patients as studies reveal good outcome from standard treatment.

Breast cancer in the very elderly: treatment patterns and complications in a tertiary cancer center

BACKGROUND

The risk of developing breast cancer rises with increasing age. The very elderly population (80 years of age and greater) is often excluded from both clinical trials and retrospective analyses. We performed a retrospective review of the very elderly population treated at our institution in order to assess treatment patterns and the safety of therapy in an older population.

DATA SOURCES

In this institutional experience at a comprehensive cancer center, we retrospectively reviewed the charts of patients 80 years and older diagnosed with a new breast cancer between September 1, 1989, and September 1, 2004.

RESULTS

Two hundred thirteen patients were identified for this study. Median age was 83 (range 80-97). Median survival was 7.28 years, with a median follow up of 4 years for patients still alive at the end of the study period. Ninety-eight percent of patients (208/213) received 1 or more components of recommended multimodality treatment. Five patients refused all treatment. Overall, complications affected 12% of patients who received treatment (26/208). There were 2 deaths, 1 after surgery and 1 related to chemotherapy. The majority, 69% (18/26), of the documented complications were classified as minor. Surgery resulted in complications in 6% (11/188) of patients. Five percent (5/112) of patients who received radiation suffered adverse effects. Chemotherapy-related complications affected 30% (6/18) of treated patients. Hormonal agents resulted in complications in 3% (3/112) of patients. No correlation between the American Society of Anesthesiologists score and incidence of complication was observed (P = .58).

CONCLUSIONS

Very elderly patients can be safely treated with surgery and radiation in accordance with accepted recommendations for their stage of breast cancer. Treatment with surgery and/or radiation should be considered despite age and moderate comorbidity in order to affect locoregional control. Chemotherapy results in a significant incidence of complications and should be cautiously implemented in this age group. A prospective trial is necessary to assess the necessity of aggressive multimodality therapy in this very elderly population.

Effect of undertreatment on the disparity in age-related breast cancer-specific survival among older women

OBJECTIVES

Assess the relationship between age and breast cancer-specific survival among older women and determine whether the observed age-related disparities in survival is explained by differences in breast cancer treatments received.

METHODS

Women > or =65 years old at diagnosis with stage I-IIIA breast cancer diagnosed between 1997 and 1998 were recruited from four regions of the United States and followed prospectively for 5 years after diagnosis. Data was obtained from tumor registries, medical records, and telephone interviews. The primary endpoint was breast cancer-specific survival. Our independent variables were age operationalized as < or =75 years vs. >75 years, and receipt of recommended guideline therapy, adapted from the National Institutes of Health guideline consensus conference.

RESULTS

Of 689 women, 36% were >75 years. Women >75 years were less likely to have received the following; axillary lymph node dissection (84% vs. 93%, P = 0.0003), radiotherapy (40% vs. 54%, P = 0.0003), definitive primary therapy (71% vs. 84%, P < 0.0001), chemotherapy (9% vs. 28%, P < 0.0001), and guideline therapy (31% vs. 54%, P < 0.0001). The 5-year breast cancer-specific survival was 95% (95% confidence interval [CI], 90%, 97%) for those < or =75 years who received guideline therapy, 94% (95% CI, 90%, 97%) for those < or =75 years who did not receive guideline therapy, 96% (95% CI, 88%, 99%) for those >75 years who received guideline therapy and 83% (95% CI, 74%, 89%) for those >75 years who did not receive guideline therapy, (P = 0.002) by the log-rank test.

CONCLUSION

Receipt of guideline therapy may reduce the age-related disparity in breast cancer survival among older women.

Determinants of early distant metastatic disease in elderly patients with breast cancer

BACKGROUND

The purpose of this analysis was to determine predictors of early distant metastasis in elderly breast cancer patients receiving hormonal therapy.

METHODS

We analyzed data from 938 patients in the North American Fareston Tamoxifen Adjuvant Trial>or=65 years old to determine predictors of early metastatic disease.

RESULTS

The median patient age was 73 (range 65 to 100). With a median follow-up of 34 months, 17 patients (1.8%) developed distant metastases. The median time to distant metastasis was 21 months. On univariate analysis, significant predictors of distant metastatic disease were as follows: progesterone receptor status (P=.032), lymphovascular invasion (P=.020), tumor grade (P=.007), tumor size (P<.01), and number of metastatic nodes (P<.01). On multivariate analysis, only the number of positive nodes (P=.029) remained significant. Patients with >or=4 positive nodes were more likely to develop early metastases than those with 0 to 3 positive nodes (odds ration 20.304; 95% confidence interval 2.777-148.456, P=.003).

CONCLUSIONS

Lymph node status in the elderly breast cancer patient treated with hormonal therapy alone is a strong predictor of early distant recurrence.

Breast surgery: minimally invasive diagnosis and treatment

The increasingly large proportion of elderly women in the United States population carries a disproportionate burden of breast cancer. The advent of minimally invasive surgical techniques applicable to breast disease has brought new opportunities to diagnose and treat breast cancer in the older population. This article reviews issues important to the evolving field of breast cancer management in older women: cancer risk and screening considerations, diagnosis and biopsy approaches, and surgical treatment options based on current studies and recommendations.

Pathological, biological and clinical characteristics, and surgical management, of elderly women with breast cancer

For this retrospective study, we divided 3814 patients with invasive operable breast cancer into five groups based on their age at diagnosis. Univariate analysis showed that the elderly women had larger tumours with more axillary node involvement and lymphovascular invasion, more estrogen- and progesterone-positive tumours, lower grades and proliferative indices, and were less likely to be c-erbB2 positive. They were more likely to have been diagnosed in a symptomatic state and to have undergone mastectomy, and less likely to have undergone mammary reconstruction or axillary dissection, or to have a family history of breast cancer. The multinomial regression model showed that pT, pN, ER, PgR, the type of diagnosis, and a family history were independently associated with each other. The results of this study show that elderly women are more likely to have larger and more frequently N+ tumours, but these are biologically less aggressive and usually seem to receive less invasive surgical treatment.
