Introduction Delay between clinical presentation and treatment of breast cancer (BC) can significantly impact mortality. We aimed at drawing a picture of women with locally advanced breast cancer (LABC) treated at our Breast Unit and at investigating factors associated with treatment delay. Material and methods A retrospective descriptive analysis, using a specific 28-item semi-structured questionnaire, was conducted in 67 patients diagnosed with T4 BC. Results Nearly a third of our patients had at least one known predisposing factor for LABC. 42% of patients did not perform routine medical breast checks, 49% reported indifference as the first feeling and 47% waited at least 3 months before seeking medical attention. The reasons for diagnostic delay were different in the various age groups. Doctor's delay in making the right diagnosis occurred in 60% of younger patients (≤40 years, n = 5), whereas among women aged 41–69years (n = 34) 50% suffered from psychiatric comorbidities. In patients ≥70 years (n = 28) social factors such as isolation, being widowed and living in a retirement home were present in most of the cases. Delay in seeking medical care was also associated with increasing age. Across all age groups, coping factors such as denial and indifference were also associated with an increase in the odds of delayed presentation, as opposed to fear. Conclusions Factors possibly explaining late medical consultation seem to differ according to age. Psychological factors are crucial in patients' delay whereas age and social factors are relevant in doctors' and system's delay. © 2017 Elsevier Ltd

Purpose: Rare cancers represent 22% of all tumors in Europe; however, the quality of the data of rare cancers may not be as good as the quality of data for common cancer. The project surveillance of rare cancers in Europe (RARECARE) had, among others, the objectve of assessing rare cancer data quality in populaton-based cancer registries (CRs). Eight rare cancers were considered: mesothelioma, liver angiosarcoma, sarcomas, tumors of oral cavity, CNS tumors, germ cell tumors, leukemia, and malignant digestve endocrine tumors. Methods: We selected data on 18,000 diagnoses and revised, on the basis of the pathologic and clinical reports (but not on pathologic specimens), unspecified morphology and topography codes originally atributed by CR officers and checked the quality of follow-up of long-term survivors of poor prognosis cancers. Results: A total of 38 CRs contributed from 13 European countries. The majority of unspecified morphology and topography cases were confirmed as unspecified. The few unspecified cases that, after the review, changed to a more specific diagnosis increased the incidence of the common cancer histotypes. For example, 11% of the oral cavity epithelial cancers were reclassified from unspecified to more specific diagnoses: 8% were reclassified as squamous cell carcinoma (commoner) and only 1% as adenocarcinoma (rarer). The revision confirmed the majority of long-term survivors revealing a relatve high proporton of mesothelioma long-term survivors. The majority of appendix carcinoids changed behavior from malignant to borderline lesions. Conclusions: Our study suggests that the problem of poorly specified morphology and topography cases is mainly one of difficulty in reaching a precise diagnosis. The awareness of the importance of data quality for rare cancers should increase among registrars, pathologists, and clinicians. © 2016 Wichtg Publishing.

Objectives: The primary objective of this population-based study is to describe the patterns of care of elderly patients with breast cancer (BC), and evaluate potential causative factors for the decrease in BC-specific survival (BCSS) in the elderly. Patients and Methods: We included all or representative samples of patients with newly diagnosed BC from seven Swiss cancer registries between 2003 and 2005 (n=4820). Surgical and non-surgical BC treatment was analyzed over 5 age groups (<65, 65 to <70, 70 to <75, 75 to <80 and ≥80. years), and the predictive impact of patient age on specific treatments was calculated using multivariate logistic regression analysis. Results: The proportion of locally advanced, metastatic and incompletely staged BC increased with age. The odds ratio for performing breast-conserving surgery (BCS) in stages I-II BC (0.37), sentinel lymph node dissection (SLND) in patients with no palpable adenopathy (0.58), post-BCS radiotherapy (0.04) and adjuvant endocrine treatment (0.23) were all in disfavor of patients ≥80. years of age compared to their younger peers. Only 36% of patients ≥80. years of age with no palpable adenopathy underwent SLND. In the adjusted model, higher age was a significant risk factor for omitting post-BCS radiotherapy, SLND and adjuvant endocrine treatment. Conclusions: This study found an increase in incomplete diagnostic assessment, and a substantial underuse of BCS, post-BCS radiotherapy, SLND and adjuvant endocrine treatment. in elderly patients with BC. There is a need for improved management of early BC in the elderly even in a system with universal access to health care services. © 2012 Elsevier Ltd.

Purpose: Biological markers are crucial factors in order to differentiate female breast cancers and to determine the right therapy. This study aims at evaluating whether testing for biomarkers for female breast cancer has similar frequency and characteristics across and within countries. Methods: Population-based cancer registries of the Association for cancer registration and epidemiology in Romance language countries (GRELL) were asked to complete a questionnaire on biomarkers testing. The data collected referred to invasive female breast cancer cases diagnosed between 2004 and 2009. The investigation focused on 1) the overexpression and amplification of the human epidermal growth factor receptor 2 oncogene (HER2); 2) the expression of oestrogen (ER) and progesterone (PgR) receptors; and 3) the proliferation index (PI). Weighted percentages, the heterogeneity among and within countries, and the correlation between responses and calendar years were evaluated. The study was based on 19,644 breast cancers. Results: Overall, 85.9% of the cases were tested for HER2, 91.8% for both ER and PgR, and 74.1% for proliferative markers. For HER2 and ER-PgR, the frequency of testing increased from 2004 to 2009. Testing varied among countries (HER2 from 82.0% to 95.9%, ER-PgR from 89.3% to 98.9%, PI from 10% to 92%) and also within the same country (e.g. HER2 in Italy from 51% to 99%) as well as within single cancer registries. The most relevant differences were in the scores for positive/negative/not clearly defined HER2 (e.g. HER2 was defined positive if IHC 3+ in 21/33 registries), and in the cut-off of positive cells for ER/PgR (from >0% to >30%) and PI positivity (from >0% to >20%). Conclusions: Biological markers are widely tested in the Romance language countries; however, the parameters defining their positivity may vary, raising concerns about homogeneity in breast cancer classification and treatment. © 2013 Elsevier Ltd.
