BACKGROUND: Time between primary melanoma excision and sentinel lymph node biopsy (SLNB) has not been sufficiently studied as an independent predictor of survival in cutaneous melanoma. OBJECTIVES: We used propensity score matching to evaluate whether early SLNB (performed ≤40 days from excisional biopsy) is associated with higher mortality in patients with cutaneous melanoma. MATERIALS & METHODS: A retrospective cohort study at a tertiary melanoma referral centre...

OBJECTIVE: While the accuracy of the SLN procedure has been validated in patients with low risk EC, its relevance for high-risk EC remains debated. The aim of this study was to evaluate the accuracy of SLN mapping in patients with high-risk EC. STUDY METHOD: We reviewed all patients with high risk EC (grade 3 endometrioid, serous, carcinosarcoma, clear cell and undifferentiated) who underwent primary surgery with SLN mapping followed by pelvic +/- paraaortic lymphadenectomy, between November 2010 and November 2016...

BACKGROUND: Studies demonstrate safety of omitting axillary nodal dissection for early-stage breast cancer with positive sentinel lymph node (+SLN) biopsy, although trial designs differed in radiation therapy (RT) fields. Regional nodal irradiation was separately shown to improve outcomes in high-risk patients. This led to lack of consensus in RT volumes. Clinical pathways (CPs) standardize care where practice varies unnecessarily. We evaluated the impact of changes to a CP guiding postoperative RT in women with +SLNs on practice patterns throughout a network...

BACKGROUND: Women ≥70 years old with clinically (c) lymph node (LN) negative (-), hormone receptor (HR) positive (+) breast cancer are recommended not to be routinely staged with a sentinel LN biopsy. We sought to determine how this affects adjuvant decision-making. METHODS: Statistical analyses were performed to determine the association of LN evaluation with adjuvant chemotherapy and radiation therapy in cLN-, HR + breast cancer patients in the National Cancer Database...

PURPOSE OF REVIEW: We review recent advancements in staging and imaging of penile cancer, including surveillance after therapy. RECENT FINDINGS: For cN0 patients, the sentinel lymph node biopsy is currently considered the preferred way for invasive staging. It has largely replaced other modalities such as staging inguinal lymphadenectomy. Its diagnostic value increases when combined with other staging modalities such as ultrasound with fine-needle aspiration cytology (US-FNAC) or fluorodeoxyglucose-PET with computed tomography (PET/CT)...

BACKGROUND Synchronous bilateral breast cancer is rare. A case is presented where whole breast irradiation (WBI) was planned after breast conserving surgery in a patient with synchronous bilateral breast cancer. A comparison was made between the feasibility of helical tomotherapy and direct tomotherapy. CASE REPORT A 60-year-old woman was found to have bilateral breast nodules on routine mammographic screening, resulting in bilateral lumpectomy and sentinel lymph node biopsy. Histopathology showed a 6 mm diameter invasive ductal carcinoma in the right breast (Grade 1, hormone receptor positive, HER2 negative) and an 8mm diameter tubular carcinoma in the left breast (Grade 1, hormone receptor positive, HER2 negative)...

Melanoma exerts immune suppressive effects to facilitate tumor progression and metastatic spread. We studied these effects on dendritic cell (DC) and T-cell subsets in 36 melanoma sentinel lymph nodes (SLN) from 28 stage I-III melanoma patients and determined their clinical significance. Four conventional DC subsets; plasmacytoid DCs; and CD4+, CD8+, and regulatory T cells (Tregs) were analyzed by flow cytometry. We correlated these data to clinical parameters and determined their effect on local and distant melanoma recurrence, with a median follow-up of 75 months...

BACKGROUND: Metastases to the thyroid are rare. The most common primary cancer to metastasize to the thyroid is renal cell carcinoma, followed by malignancies of the gastrointestinal tract, lungs, and skin, with breast cancer metastases to the thyroid being rare. Overall, the outcomes in malignancies that have metastasized to the thyroid are poor. There are no prospective studies addressing the role of surgery in metastatic disease of the thyroid. Isolated thyroidectomy has been proposed as a local disease control option to palliate and prevent the potential morbidity of tumor extension related to the airway...

HER2-directed therapies are less effective in patients with ER(pos) compared to ER(neg) breast cancer, possibly reflecting bidirectional activation between HER2 and estrogen signaling pathways. We investigated dual blockade using anti-HER2 vaccination and anti-estrogen therapy in HER2(pos)/ER(pos) early breast cancer patients. In pre-clinical studies of HER2(pos) breast cancer cell lines, ER(pos) cells were partially resistant to CD4(+) Th1 cytokine-induced metabolic suppression compared with ER(neg) cells...

BACKGROUND: The National Comprehensive Cancer Network guidelines for Merkel cell carcinoma recommend performance of the sentinel lymph node biopsy in all patients with clinically negative nodal disease for staging and treatment. Nevertheless, sentinel lymph node biopsy in the periocular region is debated as tumors are typically smaller and lymphatic variability can make performance procedurally problematic.

INTRODUCTION: Despite the advances in cutaneous melanoma management, the false-negative rates (FNRs) of sentinel lymph node biopsy (SLNB) are still high. These rates are dependent not only on the technique but also on definitional terms and percentage of head/neck melanoma (highest false-negative SLNB). Fluorescence imaging technology is well acquainted in plastic surgery and other specialties. Having demonstrated that fluorescence-assisted SLNB is effective in melanoma, we are interested in determining its FNR...

BACKGROUND: Classic techniques of delayed prosthetic breast reconstruction use the mastectomy scar as an access route. As a result, the filling of the expander must be postponed until the wounds have healed. This creates an asymmetry between the breasts with the volume changes caused by the filling of the expander, which may occur over several weeks and cause considerable discomfort. METHODS: Delayed breast reconstruction was performed via the axillary incision made for sentinel lymph node biopsy or lymphadenectomy with endoscopic assistance and detachment of the pectoralis major muscle...

Breast cancer is a socially relevant group of malignant conditions of the mammary gland, affecting both males and females. Most commonly the surgical approach of choice is a modified radical mastectomy (MRM), due to it allowing for both the removal of the main tumor mass and adjacent glandular tissue, which are suspected of infiltration and multifocality of the process, and a sentinel axillary lymph node removal. Most common post-surgical complications following MRM are the formation of a hematoma, the infection of the surgical wound and the formation of a seroma...

Lymph node status is one of the most important factors in determining prognosis and the need for adjuvant treatment in endometrial cancer (EMCA). Unfortunately, full lymphadenectomy bears significant surgical and postoperative risks. The majority of patients with clinical stage I disease will not have metastatic disease; thus, a full lymphadenectomy only increases morbidity in this population of patients. The use of the sentinel lymph node (SLN) biopsy has emerged as an alternative to complete lymphadenectomy in EMCA...

BACKGROUND AND PURPOSE: We started performing sentinel node navigation surgery (SNNS) for patients with early gastric cancer (EGC) using infrared ray electronic endoscopy (IREE) with indocyanine green injection from year 2000. The EGCs usually have complex lymphatic drainage, unidirectional or multidirectional lymphatic flow. In this study, we investigated and clarified factors that affect the direction of gastric lymphatic drainage. PATIENTS AND METHOD: Consecutive 60 patients with EGC who underwent SNNS by IREE from year 2006 to 2014 were enrolled to this study...
