BACKGROUND Phyllodes tumor (PT) is a rare neoplasm of the breast. Concomitant PT with invasive ductal carcinoma (IDC) is an even rarer occurrence. When ductal carcinoma in situ (DCIS) or IDC are detected within the specimen, the management changes from wide local excision to further staging work-up, including sentinel node biopsy and radiation. CASE REPORT We report the case of a 70-year-old presented with right breast mass whose pathology showed benign PT with concomitant IDC and DCIS. The patient elected for a wide excision of the mass with sentinel lymph node biopsy, which did not show any involvement...

Importance: More than half of all new melanoma diagnoses present as clinically localized T1 melanoma, yet sentinel lymph node biopsy (SLNB) is controversial in this population given the overall low yield. Guidelines for SLNB have focused on pathologic factors, but patient factors, such as age, are not routinely considered. Objectives: To identify indicators of lymph node (LN) metastasis in thin melanoma in a large, generalizable data set and to evaluate the association between patient age and LN positivity...

The standard approach of performing a completion axillary lymph node dissection (cALND) after a positive sentinel node for breast cancer patients is no longer generally accepted. This study applied the criterion of a 27% risk of having residual positive lymph nodes calculated by the MD Anderson nomogram to perform a cALND. This 27% cut-off is based on the number of positive non-sentinels in the Z0011 trial. A cohort of 166 cN0, sentinel positive breast cancer patients was used to validate the MD Anderson nomogram...

BACKGROUND: Axillary staging in patients with breast cancer and clinically node-negative disease is performed by sentinel node biopsy (SLNB). The aim of this study was to integrate feasible preoperative variables into nomograms to guide clinicians in stratifying treatment options into no axillary staging for patients with non-metastatic disease (N0), SLNB for those with one or two metastases, and axillary lymph node dissection (ALND) for patients with three or more metastases. METHODS: Patients presenting to Skåne University Hospital, Lund, with breast cancer were included in a prospectively maintained registry between January 2009 and December 2012...

The FIGO staging system has undergone many modifications since it first appeared in about the middle of the previous century. Due to the use of modern diagnostic tools, namely computed tomography, magnetic resonance imaging, positron emission tomography, sentinel lymph node biopsy and of neoadjuvant chemotherapy, certain gynecological cancer cases cannot be allocated to a specific stage if one wishes to adhere strictly to FIGO requirements. In these circumstances such cases remain actually unstaged. This should prompt appropriate modifications of the current FIGO staging system so that it fulfills its aims...

A sentinel lymph node biopsy is a surgical staging procedure performed for patients with primary cutaneous melanoma who are clinically lymph-node negative to determine whether there is low volume nodal metastasis in the draining lymph node field. A systematic review was recently performed to update the Australian clinical practice guidelines for the diagnosis and management of melanoma, addressing the question, 'When is a sentinel lymph node biopsy indicated?' This article discusses the findings of the systematic review and the evidence base for the updated guidelines...

BACKGROUND AND OBJECTIVES: Current literature may overestimate the risk of nodal metastasis from thin melanoma due to reporting of data only from lesions treated with SLNB. Our objective was to define the natural history of thin melanoma, assessing the likelihood of nodal disease, in order to guide selection for SLNB. METHODS: Retrospective review. The primary outcome was the rate of nodal disease. Clinicopathologic factors were evaluated to find associations with nodal disease...

Worldwide, sentinel node (SN) biopsy for accurate staging is now part of the standard work-up of patients with melanomas ≥1.0 mm Breslow thickness, as it is for staging patients with breast cancer. Nuclear medicine imaging and surgical techniques have evolved to such a degree that a SN can be identified and removed in virtually every patient. Nevertheless, some opposition to a routine SN biopsy remains, perhaps due to a failure to appreciate the serious implications of incomplete or inaccurate staging. Guided by a critical appraisal of the available evidence, this review elucidates the definition of an SN, discusses the sensitivity and specificity of the information it provides, emphasises that it is a minor staging procedure that can lead to improved survival when followed by appropriate therapy, and explains the necessarily unconventional and complex design of the only randomised trial that addresses this subject...

BACKGROUND: We investigated the results of quality control study prior to phase III trial of sentinel lymph node navigation surgery (SNNS). METHODS: Data were reviewed from 108 patients enrolled in the feasibility study of laparoscopic sentinel basin dissection (SBD) in gastric cancer. Seven steps contain tracer injection at submucosa (step 1) and at four sites (step 2) by intraoperative esophagogastroduodenoscopy (EGD), leakage of tracer (step 3), injection within 3 minutes (step 4), identification of at least one sentinel basin (SB) (step 5), evaluation of sentinel basin nodes (SBNs) by frozen biopsy (step 6), and identification of at least five SBNs at back table and frozen sections (step 7)...

Introduction: Tc-99m tilmanocept (TcTM) received recent FDA-approval for lymphatic mapping. However, no prior studies have evaluated the use of TcTM as a single agent in sentinel lymph node (SLN) biopsy in breast cancer. Methods: We executed this retrospective, pilot study to assess the ability of TcTM to identify sentinel nodes as a single agent in clinically node-negative breast cancer patients. Patients received a single, intradermal injection overlying the tumor of either 0.5 mCi TcTM the day-of surgery or 2...

BACKGROUND: Efforts are continuously made to detect and investigate the pivotal processes and interplay between the response of sentinel lymph node and malignant cells from a primary tumor. Conversely, some frequently used tumor animal models, such as human cancer xenografts, rarely feature metastasis. Therefore, lymph node alterations are seldom assessed. We consider that studying lymph node response could contribute to the understanding of host reaction to cancer. In the present study, we explored the presence of regional lymph node alterations in parallel with tumor growth using a pancreatic tumor xenograft model which does not develop metastasis...

An 88-year-old Caucasian man recently sought medical attention due to recrudescence of skin disease in the area of previously excised nodule (in 2002) on the nose dorsum. The original lesion was clinically considered as a pigmented basal cell carcinoma, after which histological examination revealed a superficial spreading melanoma in vertical growth face (Clark level IV; Breslow thickness 2.1 mm) arising from a pre-existing nevus. The adjacent skin also showed significant actinic damage both in the epidermis and in the dermis...

Sentinel lymph node (SLN) sampling may provide staging information without exposing patients to risks of lymph node dissection. There is no consensus protocol for optimal pathologic handling of these specimens. This study compares 2 ultrastaging protocols of SLN in endometrial carcinoma (EC). All SLN were serially sectioned perpendicular to the long axis in 2 mm intervals and entirely submitted for routine hematoxylin and eosin (H&E) processing. SLN negative by routine processing had ultrastaging (US) by one of the following: method 1 (M1), 5 H&E levels at 250 μm intervals with 2 unstained slides at each level; pankeratin immunohistochemistry (IHC) performed on level 1 in cases with negative H&E levels or method 2 (M2), 1 H&E level + 2 unstained slides cut 250 μm into the tissue block; pankeratin IHC performed in cases with negative H&E...

The purpose of this study was to present a novel surgical method for intraoperative precise sentinel lymph node biopsy (SLNB) and to determine its clinical efficacy and sensitivity in breast cancer patients. The sentinel lymph nodes (SLNs) were preoperatively evaluated by axillary ultrasound. The intraoperative detection of SLNs was guided by lymphatic drainage pathway. The lymphatic vessels and SLNs were visualized. During operation, we searched for all the true SLNs (trSLNs), para-SLNs (paSLNs) and post-SLNs (poSLNs) followed lymphatic drainage ducts...

Translating photoacoustic imaging into clinical setup is a challenge. Handheld clinical real-time photoacoustic imaging systems are not common. In this work, we report an integrated photoacoustic and clinical ultrasound imaging system by combining light delivery with the ultrasound probe for sentinel lymph node imaging and needle guidance in small animal. The open access clinical ultrasound platform allows seamless integration of photoacoustic imaging resulting in the development of handheld real-time photoacoustic imaging probe...
