    Purpose: We aimed to determine the elapsed time between the first notification of the disease and the accession to the diagnosis and treatment modalities and its associated factors in female patients with breast cancer in Turkey. Patients and Methods: The data was acquired by a questionnaire completed by 535 patients who applied to the 14 various oncology clinics between 1st and 28th of February 2010 in Turkey. The centers located in metrople - Istanbul, Izmir, and Ankara- were named Group 1 (n= 161), the centers located in Marmara and Central Anatolia region - Kocaeli, Bursa, Edirne and Kayseri- were named Group 2 (n= 189), and the centers located in Karadeniz and East-Southeast Anatolia region - Zonguldak, Samsun, Trabzon, Elazig and Diyarbakir- were named Group 3 (n= 185). The grouping for the centers were configured according to their socio- economic development of provinces. Results: Median age was 48 +/- 11.2 (24- 89) years, the number of patients of age less than 50 years were 282 (% 56.1). 85% of the patients detected a mass in their breast by themselves. % 27 of the patients over age 50 never had a breast ultrasound and/ or mammography done until the definite diagnosis was established. The median elapsed time between the disease noticed by the patient and the application to a health care center was 10 days, between the application and the biopsy was 19 days, between the biopsy and the surgery was 31 days. The elapsed time between recognition of the disease by the patient and the patient applying to a health care center in Group 1, Group 2, and Group 3 was 15, 10 and 14 days, respectively, and the elapsed time between the biopsy and surgery was 14, 1.5 and 12 days, respectively. The elasped time between the first recognition of the disease and applying of the patient to the health care center and the elapsed time between the biopsy and surgery in Group 2 centers was statistically significantly shorter compared to group 1 and 3 centers (p< 0.05). Conclusions: A high level of awareness of breast cancer in our country has examined through the time that is defined as 10 days between recognition of the disease and medical application. Compared with the developed countries the elapsed time between the application and biopsy, surgery and systemic therapy is longer than the expected and it has been marked differences between regions.

    Nine weeks versus 1 year adjuvant trastuzumab in patients with early breast cancer: an observational study by the Turkish Oncology Group (TOG)

    Background Optimal duration of adjuvant trastuzumab in early breast cancer is an unresolved issue. In this observational study, we compared the outcome of 9 weeks and 1 year adjuvant trastuzumab in early breast cancer patients in Turkey. Methods Records of 680 patients with HER2-positive early breast cancer who received adjuvant trastuzumab plus chemotherapy were obtained and patients were followed up to compare the disease-free survival (DFS) outcome of 9 weeks versus 1 year trastuzumab. Results Nine weeks and 1 year trastuzumab was given to 202 (29.7 %) and 478 (70.3 %) patients, respectively. There was a significantly lower rate of patients with negative lymph nodes in the 9-week trastuzumab group. At median 3 years of follow-up from the date of starting trastuzumab, the DFS rates were 88.6 and 85.6 %, respectively (p = 0.670). When adjusted for all the prognostic factors that were significant on univariate analysis, again there was no significant difference in DFS between the groups (HR 0.675; 95 % CI 0.370-1.231; p = 0.200). Cardiac toxicity defined as a >= 15 % decrease in LVEF was significantly higher in the 1-year trastuzumab group (1.88 % versus none for 1-year and 9-week trastuzumab groups, respectively; p = 0.050). Conclusion The results of this observational study suggest that DFS outcome of 9 weeks of adjuvant trastuzumab may be comparable to 1 year adjuvant trastuzumab: this needs confirmation by randomized trials.
