Sentinel node biopsy is a widely accepted alternative to primary axillary lymph node dissection for ipsilateral nodal assessment in breast cancer. We have performed a retrospective chart review in 713 consecutive patients with primary, operable breast cancer who underwent sentinel node biopsy in order to identify factors that determine the sentinel node identification rate. Chi-squared test, univariate and multivariate analyses were used to evaluate the influence of different factors on the sentinel identification rate. Among the factors investigated, tumour size was correlated with sentinel lymph nodes detection rates (multiple logistic regression, P= 0.002). In addition, the patient's age showed to be a significant influencing factor (multiple logistic regression, P= 0.006). Body mass index and grade only exhibited a significant correlation with the identification rate in the univariate (P= 0.041, P= 0.025), but not in the multivariate analysis (P= not significant). All associations were found to be independent of the site of injection. Interestingly, surgeons with intermediate expertise (11-20 prior dissections) had the highest detection rates (P= 0.004). We conclude that sentinel identification rates are higher in larger tumours and in younger patients, independent of the injection site. Surgical experience in sentinel node dissection is not linearly correlated with higher identification rates.

Background: Primary breast squamous cell carcinoma (PBSCC) is a unique histopathological type of breast cancer. The majority of current case reports of PBSCC are triple-negative tumors with poor prognosis. Due to its heterogeneous clinical course, no unified management is achieved.

Chronic inflammation in the tumour microenvironment (TME) via Th2-polarisation promotes melanoma progression and metastasis, making it a target for immunotherapy. Interleukin (IL)-4 is considered essential for Th2-polarisation in the TME; however, its source remains unknown. Basophils have been postulated as one of its sources.

Sentinel lymph node (SLN) detection has been widely investigated in recent years as a part of the surgical staging of women with endometrial cancer (EC), gradually overtaking lymphadenectomy (LND) in this respect. In this study, thirty EC patients, assumed as stage I, were investigated using superparamagnetic iron oxide (SPIO) as a tracer for SLN detection followed by LND. The endpoints of this research were the proportion of successful SLN detection, the average number of SLNs per patient, the percentage of bilaterally detected SLNs, and the proportion of metastatic SLNs.

Breast cancer is one of the most common cancers diagnosed in both countries with high and low levels of socio-academic development. Routine, regular screening tests being introduced in an increasing number of countries make it possible to detect breast cancer at an early stage of development, as a result of which the trend in the incidence of metastatic breast cancer has been decreasing in recent years. The latest guidelines for the treatment of this tumor do not recommend axillary dissection, which limits the need for rapid assessment of the nodes during surgery.

: The EndoPredict assay has been widely used in recent years to estimate the risk of distant recurrence and the absolute chemotherapy benefit for patients with estrogen (ER)-positive/human epidermal growth factor receptor 2 (HER2)-negative breast cancer. However, there are no well-defined criteria for selecting patients who may benefit from the test. The aim of this study was to develop a novel nomogram to estimate the probability of obtaining a high-risk EndoPredict result in clinical practice.
