OBJECTIVES: This study examines oncologic outcomes in patients with HPV-related oropharyngeal squamous cell carcinoma (HPV(+)OPSCC) who had evidence of gross cranial nerve invasion (CNI) identified at the time of surgery. STUDY DESIGN: Retrospective cohort study comparing demographics, clinical features, and outcomes of HPV(+)OPSCC patients with and without gross CNI. METHODS: Patients with biopsy proven HPV(+)OPSCC involving the base of tongue, tonsil, or unknown primary site, who underwent surgery as a part of their treatment between 1/1/2006-12/31/2020 (n = 874), were included in this study...

BACKGROUND: Pituitary neuroendocrinology tumors (PitNETs) with pseudocapsule can be effectively removed by the pseudocapsule-based extracapsular resection technique. In the areas without pseudocapsule, the tumor cells can spread into the adjacent tissues at the cellular level, which brings a great challenge to achieving total tumor resection. METHODS: Our surgical strategy for PitNETs with an incomplete pseudocapsule is to combine the pseudocapsule-based extracapsular resection technique with the intensive excision technique for the removal of the tumor...

Salivary gland malignant tumours are a complex and highly variable pathological group. Their diagnosis can be challenging, and management is guided by multidisciplinary teams. This project aimed to establish clinicopathological and sociodemographic features that significantly impacted overall disease-free or progression-free survival in patients diagnosed with malignant salivary gland disease between 2010 and 2019 in a tertiary referral centre. In total, 86 patients were included for analysis, with a female:male gender ratio of 1...

PURPOSE: In 95% of cases, penile cancer is a squamous cell carcinoma whose specificity is lymphatic spread with the inguinal lymph nodes as the first relay route. Inguinal lymph node dissection is a primordial part of the treatment. The objective was to assess the oncological results of inguinal lymph node dissection in penile cancer at our centre. METHODS: We retrospectively included all patients having undergone inguinal lymph node dissection at our centre between 1 January 2004 and 1 January 2020 for the treatment of penile cancer...

BACKGROUND: Standard treatment of early-stage vulvar cancer is a radical, wide, local excision of the primary tumor and a sentinel lymph node (SLN) procedure for the groins. An inguinofemoral lymphadenectomy is no longer necessary for patients who have a negative SLN or micrometastasis (<u>≤</u>2 mm). When there is macrometastasis (>2 mm) in the SLN, an inguinofemoral lymphadenectomy is indicated; however, this procedure is associated with major morbidity, such as wound healing, lymphoceles, and lymphedema...

To investigate the incidence of occult neck metastasis and to determine the prognostic factors related to the occurrence of the cervical lymph nodal metastasis and extra capsular extension (ECE) in early oral cavity cancer patients. A retrospective review performed on 100 patients with node negative squamous cell carcinoma of oral cavity who underwent primary treatment between Jan 2015 and Dec 2018. Incidence of occult neck metastasis after the elective neck dissection in our study was 35%. Independent correlates of positive occult neck metastasis were lymphovascular Invasion (P-0...

BACKGROUND: Currently, all patients with American Joint Committee on Cancer (AJCC) pT2b-pT4b melanomas and a positive sentinel node biopsy are now considered for adjuvant systemic therapy without consideration of the burden of disease in the metastatic nodes. METHODS: This was a retrospective cohort analysis of 1377 pT1-pT4b melanoma patients treated at an academic cancer center. Standard variables regarding patient, primary tumor, and sentinel node characteristics, in addition to sentinel node metastasis maximum tumor deposit size (MTDS) in millimeters and extracapsular spread (ECS) status, were analyzed for predicting disease-specific survival (DSS)...

OBJECTIVE: To establish the criteria for a risk factor score (RFS) for predicting the probability of central compartment lymph node metastasis (LNM) in papillary thyroid carcinoma (PTC) and to explore the clinical significance of the RFS. METHODS: The data of 412 patients with PTC who underwent surgical resection between May 2013 and July 2016 were retrospectively analysed and divided into two groups: a central LNM group and a non-central LNM group. In each group, the frequency of six risk factors was documented: sex, age, tumour size, extracapsular spread (ECS), tumour multifocality, and tumour location...

Locally-advanced head and neck squamous cell carcinoma (HNSCC) is mainly defined by the presence of pathologic cervical lymph nodes (LNs) with or without extracapsular spread (ECS). Current radiologic criteria to classify LNs as non-pathologic, pathologic, or pathologic with ECS are primarily shape-based. However, significantly more quantitative information is contained within imaging modalities. This quantitative information could be exploited for classification of LNs in patients with locally-advanced HNSCC by means of artificial intelligence (AI)...

PURPOSE: To analyze the clinical outcomes of patients with regional persistent/recurrent nasopharyngeal carcinoma (NPC) who received neck dissection, and to evaluate the clinical benefit of postoperative adjuvant therapy (PAT) based on patients' positive lymph node counts (PLNs), extracapsular spread (ECS) and preoperative plasma EBV DNA levels. METHODS: From 2003 to 2017, 342 patients with regional persistent/recurrent NPC were included in this study. All patients were treated with neck dissection and 76 patients received PAT...

The use of three-dimensional (3D)-printed custom-made implants is spreading in the orthopedics field for the reconstruction of bone losses or for joint replacement, thanks to their unparalleled versatility. In particular, this novel technology opens new perspectives to formulate custom-made fixation strategies for the upper cervical region, sacrum and pelvis, where reconstruction is challenging. We report and analyze the literature concerning upper cervical reconstruction with 3D-printed personalized implants after tumor surgery, and discuss two cases of patients where this technology was used to reconstruct the anterior column after extracapsular debulking of C2 recurrent chordoma at our institution...

Background: Head and neck squamous cell carcinoma (HNSC) is the 7th most common type of cancer in the world. Through the advantages of The Cancer Genome Atlas (TCGA) large-scale sequencing-based genome analysis technology, we can explore the potential molecular mechanisms that can improve the prognosis of HNSC patients. Methods: The HNSC transcriptome and clinical data were downloaded from TCGA database. A univariate survival analysis and differential expression analysis were conducted to obtain the intersection gene set...

BACKGROUND AND OBJECTIVE: Distant metastatic spread in breast cancer patients is a complex phenomenon involving several prognostic factors. We focused our analysis on early metastatic breast cancer (EMBC) (occurring during the first 36 months) versus late metastatic breast cancer (LMBC) (occurring beyond 3 years) in order to ascertain their possible differential predictive factors. METHODS: diagnostic, surgical, and follow-up data were assessed for consecutive patients with breast cancer undergoing surgery between 1997 and 2019...

BACKGROUND: Lymph mapping with sentinel node biopsy is the standard procedure for lymph node staging in patients with cutaneous melanoma with a tumor thickness of 1 mm or greater. Patients who have metastases in sentinel node must undergo complementary lymphadenectomy; however, it has not been shown to improve survival. OBJECTIVE: To know the prevalence in our setting of metastases in the product of complementary lymphadenectomy in patients with metastatic sentinel node...

OBJECTIVES: Different parameters have been identified in patients with oral squamous cell carcinomas (OSCC) that have a serious impact on survival, including residual tumour and extracapsular spread. Moreover, other factors, including the lymph node ratio (LNR) and lymph node yield (LNY), have been suggested as prognostic markers. MATERIAL AND METHODS: This retrospective study included patients diagnosed with OSCC and cervical lymph node metastases during the years 2010-2020...

Introduction: In the N0 neck the incidence of ECS might range from 13 to 60%. In this retrospective study we intended at evaluating the primary tumor and nodal characteristics that might influence the presence of ECS in early stage OSCC. Methods: The predictor variables were tumor and nodal features and the incidence of ENE was the outcome. Univariate and multivariate regression models along with ROC curve and Youden's J statistics was used for analysis. A p value < 0...

METHODS: Utilizing the National Cancer Database, we performed a retrospective cohort study of 7975 patients with oral cavity squamous cell carcinoma and varying degrees of extranodal extension who underwent primary surgical intervention...

The thyroid is a rare site of colorectal metastasis, comprising 0.1% of the surgical case series. A 62-year-old woman with caecal adenocarcinoma and previously surgically resected lung and liver metastases presented incidentally with a right thyroid nodule, which had grown and become symptomatic. Imaging revealed the nodule to have extracapsular spread, and cytology demonstrated metastatic adenocarcinoma. The patient underwent a technically challenging right thyroidectomy and neck dissection, with the final histopathological review demonstrating metastatic adenocarcinoma from a colorectal primary...

BACKGROUND: Recurrences remain an important problem in laryngeal squamous cell carcinoma. Little has been described about histological characteristics of the primary laryngeal tumor that may be associated with recurrences. Identifying risk factors for recurrences might help in adapting treatment or follow-up. Using real-life population-based data, we aimed to identify histological features of the primary tumor associated with recurrences and overall survival. MATERIAL AND METHODS: Demographic, clinical and treatment information on all first primary invasive laryngeal tumors diagnosed in 2010-2014 (N = 3705) were extracted from the population-based nationwide Netherlands cancer registry (NCR) and linked to PALGA, the nationwide Dutch pathology registry, to obtain data on histological factors and recurrences...
