BACKGROUND: Most trials in head and neck cancer emphasize locoregional control, as this is the main pattern of therapy failure. However, up to 15% of patients develop distant metastases. The purpose of this study was to present the investigated factors associated with distant metastasis in a single-center patient cohort. METHODS: A retrospective analysis of a single-center patient cohort over an 18-year period has been performed. We report on prevalence and incidence of distant metastasis, timing in relation to locoregional failure, Kaplan-Meier analysis for actuarial distant control rates, and univariate analysis taking into account histological, etiologic, surgical, site-dependent, stage-dependent characteristics, modality of primary therapy, and locoregional control...

PURPOSE: The present study aimed to evaluate the clinicopathologic characteristics of patients with extranodal extension (ENE) and the prognostic implications of ENE in stage III colorectal cancer (CRC). RESULTS: ENE was more frequent in younger patients and those with rectal cancer, higher T stage, higher N stage, lymphovascular invasion (LVI), and perineural invasion (PNI). Five-year disease-free survival (DFS) and overall survival (OS) were lower in patients with ENE-positive than in those with ENE-negative tumors (DFS, 66...

BACKGROUND: The identification of extrinsic tongue muscle invasion in oral cavity cancer remains challenging. Notably, the most recent American Joint Committee on Cancer (AJCC 2017, 8th edition) staging manual indicates that extrinsic muscle invasion does not lead to the diagnosis of a T4 tumor. Because this approach carries the risk of tumor downstaging, we compared the clinical outcomes of patients with oral tongue squamous cell carcinoma (SCC) staged as pT3 vs. pT4 according to the AJCC 2010, 7th edition criteria...

BACKGROUND Follicular B cell lymphomas account for a significant portion of all newly diagnosed non-Hodgkin's lymphomas. While involvement can be varied, the most common extranodal presentation is within the gastrointestinal tract beyond the stomach. In addition, the stomach has a diffuse multivessel vascular supply, which decreases the likelihood of developing ischemic gastritis. CASE REPORT An 89-year-old woman with history of diabetes, deep venous thromboembolism, and hypertension was referred due to a newly diagnosed retroperitoneal mass...

The main purpose of the TNM system is to provide an anatomic-based classification to adequately depict cancer prognosis. Accurate cancer staging is important for treatment selection and outcome prediction, research design, and cancer control activities. To maintain clinical relevance, periodical updates to TNM are necessary. The recently published 8th edition TNM classification institutes the following changes to the staging of head and neck (excluding thyroid cancer): new stage classifications [HPV-related oropharyngeal cancer (HPV+ OPC) and soft tissue sarcoma of the head and neck (HN-STS)] and modification of T and N categories [T and N categories for nasopharyngeal cancer (NPC), T categories for oral cavity squamous cell carcinomas (OSCC), N categories for non-viral related head and neck cancer and unknown primary (CUP), and T categories for head and neck cutaneous carcinoma]...

We aimed to evaluate whether obese women experience more advanced invasive breast carcinoma (IBC) with a higher number of involved lymph nodes, higher range of axillary lymph node ratio (LNR) and presence and size of extracapsular extension as it may have an impact on prognosis and management. 245 patients diagnosed with IBC were divided into normal weight (NW), overweight (OW) and obese (OB) groups. Patients were divided into high range of LNR (LNR over or equal to 0.2) and low LNR (LNR less than 0.2). The extracapsular extension dimensions were measured on the original slides of each case and grouped into ≤ 1 mm and > 1 mm...

The extranodal extension (ENE) of nodal metastasis involves the extension of neoplastic cells through the lymph node capsule into the perinodal adipose tissue. This morphological feature has recently been indicated as an important prognostic factor in various cancer types, but its role in prostate cancer is still unclear. We aimed to clarify it, performing the first meta-analysis on this issue, comparing prognostic parameters in surgically treated, node-positive prostate cancer patients with (ENE+) vs. without (ENE-) ENE...

The contribution of Epstein Barr virus (EBV) and Kaposi sarcoma herpes virus (KSHV) to the development of specific types of malignant lymphomas occurring in the human immunodeficiency virus (HIV) setting has been extensively studied since the beginning of the HIV epidemic 35 years ago. The introduction of highly active antiretroviral therapies (HAART) in 1996 has changed dramatically the incidence of HIV-related malignancies. Nevertheless, malignant lymphomas continue to be the major group of malignances observed in HIV infected individuals, and the most common cause of cancer related-deaths...

BACKGROUND: Certain patient demographics and histopathologic features are risk factors for papillary thyroid cancer (PTC) recurrence after initial treatment. Our objective was to determine whether very young age is associated with aggressive pathologic features in patients with PTC. MATERIALS AND METHODS: A retrospective analysis was performed for PTC patients who underwent surgical treatment at the University of Michigan between 2006 and 2012. Patients with known distant metastases were excluded...

Mantle cell lymphoma (MCL) is a mature B-cell non-Hodgkin lymphoma. Patients with MCL generally present with extensive lymphadenopathy and extranodal involvement. To the best of our knowledge, no cases of primary bone MCL with multiple vertebral compression fractures have been reported in the literature thus far. The current study reports the case of a 75-year-old Chinese male patient presenting with lower back pain for 1 year. B symptoms were not observed in the patient's medical history. X-ray revealed osteoporosis, and mixed osteolytic and osteosclerotic lesions in the T10 and L1 vertebrae with decreased height...

Background: Lymph node metastasis with extranodal extension represents one of the most important adverse prognostic factors for survival in patients with head and neck squamous cell carcinoma. We propose that extranodal extension occurs to differing extents. The aim of this study was to determine the prognostic significance of extranodal extension in patients with head and neck squamous cell carcinoma. Methods: Two hundred and ninety-eight patients with head and neck squamous cell carcinoma who underwent surgical resection and neck dissection were included...

Extranodal natural killer (NK)/T-cell lymphomas are rare, highly aggressive tumors of the central nervous system (CNS) that commonly affect the nasal cavity or paranasal sinuses. NK/T-cell lymphomas are associated with a poor prognosis, as they exhibit a wide range of unique clinical presentations and neuroimaging findings that are currently difficult to detect. Pathological examination is considered to be more reliable for defining the pathological entity of NK/T-cell lymphoma. Early testing for fluorodeoxyglucose (FDG)-positron emission tomography combined with computed tomography may improve the evaluation of lymphomas, which have been known to display avid (18)FDG uptake...

Objective Thyroidectomy with extensive multicompartment bilateral neck dissections for advanced-stage thyroid cancer may lead to increased risk of complications, including bilateral recurrent laryngeal nerve (RLN) paralysis and hypoparathyroidism. A planned staged approach derived from a detailed preoperative radiographic map is associated with a low complication profile. This study evaluates oncologic results and safety of neural monitored, staged thyroid cancer surgery for management of advanced thyroid cancer...

A 75-year-old female with a past medical history significant for prior stroke and atrial fibrillation presented with acute onset of orbital apex syndrome with chemosis and periorbital ecchymosis. Following initial treatment to relieve intraocular pressure, she began spontaneously haemorrhaging retro-orbitally. Preliminary investigation with neuroimaging demonstrated a left orbital mass with extension into the orbital apex. A provisional diagnosis of cavernous haemangioma was made. She was treated with transorbital resection of the orbital mass...

Extranodal lymphomas are quite rare, and they usually present as non-Hodgkin lymphomas. The most common localization is the gastrointestinal tract, mainly the stomach - primary gastric lymphoma; histologically, diffuse large B-cell lymphoma (DLBCL) is the most frequent type. The diagnosis is established based on endoscopic examination with biopsy of the tumor. It is an aggressive tumor, highly chemosensitive, which is why primary systemic chemotherapy is indicated in early, as well as late, stages of the disease...

BACKGROUND: Extranodal (or extracapsular) extension (ENE) is an adverse prognostic factor in patients with head and neck cancers who undergo primary surgery. However, the significance of ENE in human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) is not well established, and single-institution studies have not established that ENE predicts inferior outcome. The authors investigated the prognostic value of ENE in HPV-positive patients who underwent primary surgery and whether adjuvant chemoradiation improved overall survival (OS) compared with radiation alone in ENE-positive patients...
