BACKGROUND: To stage axillary lymph nodes in women with early-stage breast cancer, sentinel lymph node biopsy (SLNB), rather than axillary lymph node dissection (ALND), has been employed. Moreover, different tracer methods have various advantages and disadvantages. In recent years, carbon nanoparticle suspensions (CNSs) have been used as lymph node tracers during surgeries for thyroid cancer, gastric cancer, and colorectal cancer. The study retrospectively analyzed the feasibility and accuracy of CNS for sentinel lymph node (SLN) mapping in patients with early breast cancer...

BACKGROUND: Head and neck melanoma is associated with a high false negative (FN) sentinel lymph node biopsy (SLNB) rate. If techniques are developed that can decrease FN SLNBs, better prognostic information will be obtained, and it may be possible to improve overall survival as patients are assigned to the appropriate adjuvant management. Our group previously demonstrated that the combination of lymphoscintigraphy and indocyanine green (ICG) fluorescence-based technology was feasible for SLNB in primary melanoma...

Knowledge of the pathology of axillary lymph nodes (ALN) in breast cancer patients is critical for determining their treatment. Ultrasound is the best noninvasive evaluation for the ALN status. However, the correlation between negative ultrasound results and the sentinel lymph nodes (SLN) pathology remains unknown. To test the hypothesis that negative ultrasound results of ALN predict the negative pathology results of SLN in breast cancer patients, we assessed the association between ALN ultrasonography-negative results and the SLN pathology in 3115 patients with breast cancer recruited between October 2010 and April 2016 from a single cancer center, prospective database...

OBJECTIVES: Human papilloma virus (HPV) has been implicated in several types of epithelial cancer. The role of HPV in breast carcinogenesis has been a matter of debate fueled by conflicting reports in recent years. The aim of this study is to identify the prevalence of breast and cervical HPV infection in cancer patients by using a modern microarray approach. MATERIALS AND METHODS: In the present prospective study, 201 breast cancer patients were included. For each patient a detailed medical history was taken and during the operation, under sterile conditions, samples were collected, from the tumour, the healthy adjacent breast tissue and any positive sentinel lymph nodes...

Lymphadenectomy is considered an integral part of comprehensive surgical staging of endometrial cancer but debate on the value of lymphadenectomy continues in early-stage endometrial cancer. The aim of our study was to determine the number of node positive patients in clinically early-stage low-grade (G1-G2) endometrioid endometrial cancer. We retro-prospectively analyzed the medical records of 155 women with endometrial pathology coming to the BLK cancer center between January 2015 and December 2017 and studied 60 patients of FIGO grade 1-2 endometrioid endometrial cancer confined to the uterus to determine the nodal positivity...

BACKGROUND: ABP 980 (Amgen Inc, Thousand Oaks, CA, USA) is a biosimilar of trastuzumab, with analytical, functional, and pharmacokinetic similarities. We compared the clinical safety and efficacy of ABP 980 with that of trastuzumab in women with HER2-positive early breast cancer. METHODS: We did a randomised, multicentre, double-blind, active-controlled equivalence trial at 97 study centres in 20 countries, mainly in Europe and South America. Eligible women were aged 18 years or older, had histologically confirmed HER2-positive invasive early breast cancer, an Eastern Cooperative Oncology Group performance status score of 0 or 1, and were planning to have surgical resection of the breast tumour with sentinel or axillary lymph node dissection and neoadjuvant chemotherapy...

RATIONALE: Small cell carcinoma of the ovary (SCCO) is a rare and aggressive extra-pulmonary variant of small cell tumors of uncertain histogenesis. The pathogenesis and optimal treatment of SCCO is unclear. We present a very rare case of a synchronous primary ovarian small cell carcinoma and endometrioid adenocarcinoma of the uterus in a patient after 2 years of tamoxifen treatment for breast cancer. This is the first such report in the English literature. PATIENT CONCERNS: A 46-year-old woman had a history of left breast cancer that was treated with a simple mastectomy and sentinel lymph node biopsy in 2013...

BACKGROUND: Patients with thick primary melanomas (≥4 mm) have highly variable survival outcomes. Cell proliferation marker Ki-67 has been identified as promising biomarker in thick melanoma but has not been evaluated since the wide spread adoption of sentinel lymph node biopsy. We revisit its prognostic relevance in the sentinel node era. METHODS: We studied patients with thick (≥4 mm) primary melanoma prospectively enrolled in a clinicopathological biospecimen database from 2002 to 2015, and evaluated the prognostic value of Ki-67 expression while controlling for features included in the existing staging criteria...

Background: Historically, external ear melanomas have been treated aggressively, due to early perceptions suggesting they had poor prognosis and aggressive biological behavior. More recent evidence has not supported these notions. Methods: We completed a complete review of the literature involving malignant melanoma of the external ear. We then completed a quantitative analysis on seventy-three cases from 8 reports that contained case-level data, assessing factors that influence recurrence, and assessing characteristics of the melanomas based on histological subtype...

Managing pregnant patients with a history of melanoma or with a melanoma diagnosis can be daunting and confusing for dermatologists. We present three clinical scenarios that raise questions about the safety of pregnancy in patients with a history of melanoma, skin biopsies during pregnancy, and excisions and sentinel lymph node biopsies during pregnancy. Our recommendations incorporate the most up-to-date clinical data to help guide clinicians when faced with pigmented lesions and melanoma in a pregnant patient...
