The authors provide a perspective on the rapidly evolving field of prognostic analyses designed to quantify the risk of local recurrence in conservatively treated ductal carcinoma in situ (DCIS). These include morphologic features variously defined, nomograms, algorithms and multi-gene expression assays-all of which have completed against the perceived conclusions of the randomized trials of irradiation and Tamoxifen for DCIS: "all subsets benefit". At present the majority of newly diagnosed DCIS can be adequately treated with surgery alone. A number will require irradiation to achieve acceptable local control, and a minority will require mastectomy regardless of adjuvant treatments. Differences in the definition of prognostic factors and in the methods used to establish them is a major reason for the lack of consensus in treatment recommendation. © 2014 Wiley Periodicals, Inc.

The University of Southern California/Van Nuys Prognostic Index (USC/VNPI) is an algorithm that quantifies five measurable prognostic factors known to be important in predicting local recurrence in conservatively treated patients with ductal carcinoma in situ (DCIS) (tumor size, margin width, nuclear grade, age, and comedonecrosis). With five times as many patients since originally developed, sufficient numbers now exist for analysis by individual scores rather than groups of scores. To achieve a local recurrence rate of less than 20% at 12 years, these data support excision alone for all patients scoring 4, 5, or 6 and patients who score 7 but have margin widths ≥3 mm. Excision plus RT achieves the less than 20% local recurrence threshold at 12 years for patients who score 7 and have margins <3 mm, patients who score 8 and have margins ≥3 mm, and for patients who score 9 and have margins ≥5 mm. Mastectomy is required for patients who score 8 and have margins <3 mm, who score 9 and have margins <5 mm and for all patients who score 10, 11, or 12 to keep the local recurrence rate less than 20% at 12 years. DCIS is a highly favorable disease. There is no difference in mortality rate regardless of which treatment is chosen. The USC/VNPI is a numeric tool that can be used to aid the treatment decision-making process. © 2015 Wiley Periodicals, Inc. Source

The objective of this study was to estimate the survival time of patients referred to the palliative care unit of the National Cancer Institute of Brazil (INCA), using the Palliative Prognostic (PaP) score, and thereby evaluate this tool in a location and population different from that in which the instrument was originally developed. In this prospective study, the instrument, after translation and adaptation to Brazilian Portuguese, was applied to 250 women consecutively referred to the palliative care unit of INCA, who had been followed up as outpatients between June 2005 and August 2006. The PaP score subdivided a heterogeneous population into three homogeneous risk groups with respect to survival time, and the differences between groups were statistically significant. The median overall survival time, calculated using the Kaplan-Meier method, for the three groups was 142 days (95% confidence interval [CI]: 118-172) for Group A, 39 days (95% CI: 28-52) for Group B, and nine days (95% CI: 1-24) for Group C. The percentage survival at 30 days for the three groups was 91.4%, 57.1%, and 0%, respectively. The longer survival time found in the first group in this study would appear to reflect the referral of patients in better clinical condition for outpatient follow-up in this institute. These data suggest that the PaP score is a consistent and easily applied instrument that allows more accurate prognostication in advanced cancer patients with no possibility of cure, irrespective of the geographical location. © 2010 U.S. Cancer Pain Relief Committee.

Background: Breast cancer is the leading cause of cancer death amongst Singapore women. There are few studies evaluating the impact of mammographic screening among Asian women. This study aimed to examine differences in disease stage at presentation and outcome between breast cancer patients who were detected by screening (screen-detected) and those who presented symptomatically (symptomatic) from the experience of a regional hospital in Singapore. We also sought to identify the demographic profile of patients who were less likely to be screen detected. Methods: Retrospective data fpr female patients diagnosed with primary breast cancer and treated from January 2002 - December 2008 were analyzed. Univariate and multivariate analyses were performed to examine the profile of symptomatic as opposed to screen-detected patients and factors that influence presentation at an early disease stage. Survival and recurrence rates were computed by Kaplan-Meier method and compared by log rank test. Results: The study population consisted of 82 screen-detected and 679 symptomatic patients. The screen-detected patients were more likely to present at an earlier stage and have better overall cancer-specific survival as compared to symptomatic patients. Malay women and those without a family history of breast cancer were less likely to be detected by screening. Conclusions: Mammographic screening appeared to enable the detection of oncologically more favorable lesions and conferred better overall cancer-specific survival in Singapore women. There is possibly room for more targeted education efforts to reach out to Malay women and those without a family history of breast cancer to enable earlier disease detection among these individuals through regular breast cancer screening.

Menopause | Year: 2011

OBJECTIVES: The aims of this study were to investigate the frequency of menopausal and sexual symptoms and the proportion of sexually active women and to assess and identify quality of life (QOL) predictors in gynecologic cancer survivors. METHODS: A prospective case series following a cohort of women under radiation therapy was conducted, including 107 women (aged 21-75 y) with gynecologic cancer (cervical or endometrial cancer) who underwent pelvic radiotherapy in the Radiotherapy Division of the Women's Integral Healthcare Center at the Universidade Estadual de Campinas. Adverse effects of radiotherapy were evaluated using the Common Terminology Criteria Adverse Event Scale. QOL was measured using the abbreviated version of the World Health Organization's Quality of Life instrument before radiotherapy (T0) and at 4 months (T1), 1 year (T2), and 3 years (T3) after radiotherapy. QOL scores were assessed over time using the Wilcoxon signed-rank test. Multiple linear regression analysis was used to identify QOL predictors. RESULTS: A decrease in the frequency of vaginal dryness (26.7% in T0 vs 8.3% in T3; P < 0.01) and an increase in the proportion of sexually active women (21.5% in T0 vs 44.2% in T3; P < 0.01) were observed. A significant increase in QOL scores was observed in the psychological domain and general health and overall QOL. Dyspareunia negatively affected the physical (P < 0.01), psychological (P < 0.01), and social relationship domains (P < 0.01); overall QOL (P = 0.01); and general health (P = 0.04). Family income was positively related to environment domain (P < 0.01), overall QOL (P = 0.04), and general health (P < 0.01). CONCLUSIONS: Data derived from this study indicated that gynecologic cancer survivors had a lower frequency of vaginal dryness and a higher proportion of these women were sexually active 3 years after completion of radiotherapy. Furthermore, QOL improved and dyspareunia negatively affected various QOL dimensions. © 2011 by The North American Menopause Society. Source
