Observational Study
Triple negative breast cancer: clinical characteristics in the different histological subtypes.
To investigate the clinical behavior of triple negative breast cancer (TNC), including age distribution, occurrence of LN (lymph node) invasion and prognosis in different histological subtypes. ⋯ TNC is not a uniform disease. Different histological subtypes have different age distribution and behavior. The prognosis of the most common histological subgroup, IDC-NOS, is better in older patients, but this is counterbalanced by significantly decreased use of chemotherapy and radiotherapy.

With modern scalp cooling equipment cytotoxic damage of hair root cells can be prevented in half of the patients with cancer at high risk of alopecia. However, traditionally doubt has existed whether scalp cooling might facilitate hiding and disseminating scalp skin metastases and thus decrease survival. ⋯ We found it rather unlikely that the incidence of scalp skin metastases might increase at all after scalp cooling, whereas a very small proportion of patients receiving chemotherapy are at risk to develop metastases at this site. Scalp cooling can thus safely be offered to patients treated with alopecia-inducing chemotherapy.

Re-excision is a necessary procedure in obtaining clean margins for breast-conserving surgery (BCS)-treated patients. Re-excision rates vary widely among different breast cancer management procedures. The aim of this study was to evaluate the efficacy of ultrasound (US)-guided BCS to decrease the re-excision rate in patients with US-detectable breast cancer, as well as the relationship between positive margins and ultrasonographic characteristics of tumor. ⋯ Breast US is an effective modality for intraoperative tumor localization and can thus help obtain clean margins and reduce the re-excision rate in cases in which breast-conserving therapy has been performed. Furthermore, frozen section analysis of cavity shaved margins is a feasible method for minimizing the need for further surgery.

Patients with screen detected breast cancer tend to have small, non-palpable tumours with favourable characteristics for breast conserving surgery (BCS). The aims of this study were to analyse patterns in surgical management in patients with screen detected breast cancer and to determine factors predictive of the need for a re-operation after BCS (re-excision or secondary mastectomy). ⋯ The need for a second operation after breast conserving surgery in patients with screen-detected breast cancer has decreased significantly in the southern Netherlands since 1999. However, considerable variation in surgical approach and re-operation rate between hospitals was observed.
