Undertreatment Strongly Decreases Prognosis of Breast Cancer in Elderly Women

PURPOSE No consensus exists on therapy of elderly cancer patients. Treatments are influenced by unclear standards and are usually less aggressive. This study aims to evaluate determinants and effect of treatment choice on breast cancer prognosis among elderly patients. PATIENTS AND METHODS We reviewed clinical files of 407 breast cancer patients aged >/= 80 years recorded at the Geneva Cancer Registry between 1989 and 1999. Patient and tumor characteristics, general health status, comorbidity, treatment, and cause of death were considered. We evaluated determinants of treatment by logistic regression and effect of treatment on mortality by Cox model, accounting for prognostic factors. RESULTS Age was independently linked to the type of treatment. Overall, 12% of women (n = 48) had no treatment, 32% (n = 132) received tamoxifen only, 7% (n = 28) had breast-conserving surgery only, 33% (n = 133) had mastectomy, 14% (n = 57) had breast-conserving surgery plus adjuvant therapy, and 2% (n = 9) received miscellaneous treatments. Five-year specific breast cancer survival was 46%, 51%, 82%, and 90% for women with no treatment, tamoxifen alone, mastectomy, and breast-conserving surgery plus adjuvant treatment, respectively. Compared with the nontreated group, the adjusted hazard ratio of breast cancer mortality was 0.4 (95% CI, 0.2 to 0.7) for tamoxifen alone, 0.4 (95% CI, 0.1 to 1.4) for breast-conserving surgery alone, 0.2 (95% CI, 0.1 to 0.7) for mastectomy, and 0.1 (95% CI, 0.03 to 0.4) for breast-conserving surgery plus adjuvant treatment. CONCLUSION Half of elderly patients with breast cancer are undertreated, with strongly decreased specific survival as a consequence. Treatments need to be adapted to the patients health status, but also should offer the best chance of cure.

Complete Excision of Primary Breast Tumor Improves Survival of Patients With Metastatic Breast Cancer at Diagnosis

PURPOSE Surgery of the primary tumor usually is not advised for patients with metastatic breast cancer at diagnosis because the disease is considered incurable. In this population-based study, we evaluate the impact of local surgery on survival of patients with metastatic breast cancer at diagnosis. METHODS We included all 300 metastatic breast cancer patients recorded at the Geneva Cancer Registry between 1977 and 1996. We compared mortality risks from breast cancer between patients who had surgery of the primary breast tumor to those who had not and adjusted these risks for other prognostic factors. RESULTS Women who had complete excision of the primary breast tumor with negative surgical margins had a 40% reduced risk of death as a result of breast cancer (multiadjusted hazard ratio [HR], 0.6; 95% CI, 0.4 to 1.0) compared with women who did not have surgery (P = .049). This mortality reduction was not significantly different among patients with different sites of metastasis, but in the stratified analysis the effect was particularly evident for women with bone metastasis only (HR, 0.2; 95% CI, 0.1 to 0.4; P = .001). Survival of women who had surgery with positive surgical margins was not different from that of women who did not have surgery. CONCLUSION Complete surgical excision of the primary tumor improves survival of patients with metastatic breast cancer at diagnosis, particularly among women with only bone metastases.

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 physicians 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 patients general health status, but should also offer the best chance of cure.

Feasibility and cost-effectiveness of standardised second-line drug treatment for chronic tuberculosis patients: a national cohort study in Peru

BACKGROUND There are no data on the feasibility and cost-effectiveness of using second-line drugs to treat patients with chronic tuberculosis, many of whom are infected with multidrug resistant (MDR) strains of Mycobacterium tuberculosis, in low or middle-income countries. METHODS A national programme to treat chronic tuberculosis patients with a directly observed standardised 18-month daily regimen, consisting of kanamycin (3 months only), ciprofloxacin, ethionamide, pyrazinamide, and ethambutol, was established in Peru in 1997. Compliance and treatment outcomes were analysed for the cohort started on treatment between October, 1997, and March, 1999. Total and average costs were assessed. Cost-effectiveness was estimated as the cost per DALY gained. FINDINGS 466 patients were enrolled; 344 were tested for drug susceptibility and 298 (87%) had MDR tuberculosis. 225 patients (48%) were cured, 57 (12%) died, 131 (28%) did not respond to treatment, and 53 (11%) defaulted. Of the 413 (89%) patients who complied with treatment, 225 (55%) were cured. Among MDR patients, resistance to five or more drugs was significantly associated with an unfavourable outcome (death, non-response to treatment, or default; odds ratio 3.37, 95% CI 1.32-8.60; p=0.01).

Diet and overall survival in a cohort of very elderly people.

Objective: To evaluate the efficacy of a treatment programme for patients with fibromyalgia (FM) based on self management, using pool exercises and education. Methods: Randomised controlled trial with a 6 month follow up to evaluate an outpatient multidisciplinary programme; 164 patients with FM were allocated to an immediate 6 week programme (n = 84) or to a waiting list control group (n = 80). The main outcomes were changes in quality of life, functional consequences, patient satisfaction and pain, using a combination of patient questionnaires and clinical examinations. The questionnaires included the Fibromyalgia Impact Questionnaire (FIQ), Psychological General Well-Being (PGWB) index, regional pain score diagrams, and patient satisfaction measures. Results: 61 participants in the treatment group and 68 controls completed the programme and 6 month follow up examinations. Six months after programme completion, significant improvements in quality of life and functional consequences of FM were seen in the treatment group as compared with the controls and as measured by scores on both the FIQ (total score p = 0.025; fatigue p = 0.003; depression p = 0.031) and PGWB (total score p = 0.032; anxiety p = 0.011; vitality p = 0.013,). All four major areas of patient satisfaction showed greater improvement in the treatment than the control groups; between-group differences were statistically significant for “control of symptoms”, “psychosocial factors”, and “physical therapy” No change in pain was seen. Conclusion: A 6 week self management based programme of pool exercises and education can improve the quality of life of patients with FM and their satisfaction with treatment. These improvements are sustained for at least 6 months after programme completion.

Socioeconomic Status and Survival of Persons with Aids before and after the Introduction of Highly Active Antiretroviral Therapy

PURPOSE In the current pTNM classification system, nodal status of breast cancer is based on the number of involved lymph nodes and does not account for the total number of lymph nodes removed. In this study, we assessed the prognostic value of the lymph node ratio (LNR; ie, ratio of positive over excised lymph nodes) as compared with pN staging and determined its optimal cutoff points. PATIENTS AND METHODS From the Geneva Cancer Registry, we identified all women diagnosed with node-positive breast cancer between 1980 and 2004 (n = 1,829). The prognostic value of LNRs was calculated for values ranging from 0.05 to 0.95 by Cox regression analysis and validated by bootstrapping. Based on maximum likelihood, we identified cutoff points classifying women into low-, intermediate-, and high-risk LNR groups. RESULTS Optimal cutoff points classified patients into low- (< or = 0.20), intermediate- (> 0.20 and < or = 0.65), and high-risk (> 0.65) LNR groups, corresponding to 10-year disease-specific survival rates of 75%, 63%, and 40%, and adjusted mortality risks of 1 (reference), 1.78 (95% CI, 1.46 to 2.18), and 3.21 (95% CI, 2.54 to 4.06), respectively. In contrast to LNR risk categories, survival curves of pN2 and pN3 crossed after 15 years, and their adjusted mortality risks showed overlapping CIs: 2.07 (95% CI, 1.69 to 2.53) and 2.84 (95% CI, 2.23 to 3.61), respectively. CONCLUSION LNR predicts survival after breast cancer more accurately than pN classification and should be considered as an alternative to pN staging.
