1. Analysis of the related risk factors of inguinal lymph node metastasis in patients with penile cancer: A cross-sectional study
ABSTRACT Purpose: To determine independent predictors of inguinal lymph node (ILN) metastasis in patients with penile cancer. Patients and methods: We retrospectively analyzed all patients with penile cancer who underwent surgery at our medical center in the last ten years (n=157). Using univariate and multivariate logistic-regression models, we assessed a

2. Signet ring cells in carcinomatous lymphangitis due to gastric adenocarcinoma,
Abstract Cutaneous metastases are rare. They usually present as nodules or tumors. Diagnosis is based on histopathological examination and prognosis is unfavorable. This report describes the case of a female patient, 72 years old, with surgically treated gastric antrum adenocarcinoma. Pathology showed poorly differentiated adenocarcinoma with signet ring cel

3. Diagnostic role of ultrasound elastography on lymph node metastases in patients with head and neck cancer
Resumo Introdução: A ultrassonografia é o método mais fácil e não invasivo para diagnosticar metástases em linfonodos em pacientes com câncer de cabeça e pescoço. No entanto, como as tomografias computadorizadas são frequentemente preferidas na avaliação de tumores primários desses pacientes, as informações sobre metástases linfáticas tamb

4. Systemic dissemination of glioblastoma: literature review
RESUMO INTRODUÇÃO: Glioblastoma (GBM) é o tumor maligno mais comum do sistema nervoso central em adultos. Entretanto, metástase a distância de GBM é um evento extremamente raro. O presente estudo teve o objetivo de realizar uma revisão da literatura para avaliar os possíveis mecanismos biológicos relacionados com a ocorrência de metástase a dist�

5. Complete lymphadenectomy following positive sentinel lymph node biopsy in cutaneous melanoma: a critical review
Abstract: Cutaneous melanoma is the solid neoplasia with the highest growing incidence among all tumors. It spreads predictably to the lymphatic vessels and sentinel lymph node, and when the latter is affected the prognosis worsens dramatically. Sentinel lymph node biopsy is considered when thickness of the primary tumor exceeds 1mm and/or when there are adv

6. Saphenous-sparing laparoscopic inguinal lymphadenectomy
ABSTRACT Introduction: Inguinal lymphadenectomy is an integral part in the management of penile cancer. Video endoscopic inguinal lymphadenectomy (VEIL) is emerging as a minimally invasive treatment to reduce postoperative complications. Materials and Methods: 62 years old man underwent glansectomy for a squamous cell carcinoma (pT1b). At the physical exam

7. Robot-Assisted Extended Pelvic Lymph Nodes Dissection for Prostate Cancer: Personal Surgical Technique and Outcomes
Objective: Extended pelvic lymph nodes dissection (EPLND) allows the removal of a higher number of lymph nodes than limited PLND. The aims of this study were to describe our robot-assisted EPLND (RAEPLND) technique with related complications, and to report the number of lymph nodes removed and the rate of lymph nodal metastasis. Materials and Methods: 153

8. Cutaneous metastasis of a breast cancer diagnosed 13 years before
AbstractMetastasis is defined as a neoplastic lesion originating from another primary tumor, with which it is no longer in contact. Cutaneous metastases result from lymphatic embolization, hematogenous or contiguous dissemination or also direct implantation during surgical procedures. In women, the tumor most likely to metastasize to skin is breast cancer, w

9. The role of intratumoral lymphovascular density in distinguishing primary from secondary mucinous ovarian tumors
OBJECTIVE: Ovarian mucinous metastases commonly present as the first sign of the disease and are capable of simulating primary tumors. Our aim was to investigate the role of intratumoral lymphatic vascular density together with other surgical-pathological features in distinguishing primary from secondary mucinous ovarian tumors. METHODS: A total of 124 ca

10. Human Papilloma Virus: Prevalence, distribution and predictive value to lymphatic metastasis in penile carcinoma
Objectives To evaluate the prevalence, distribution and association of HPV with histological pattern of worse prognosis of penile cancer, in order to evaluate its predictive value of inguinal metastasis, as well as evaluation of other previous reported prognostic factors. Material and Methods Tumor samples of 82 patients with penile carcinoma were tested

11. p16 (INK4a) has clinicopathological and prognostic impact on oropharynx and larynx squamous cell carcinoma
CDKN2A encodes proteins such as p16 (INK4a), which negatively regulate the cell-cycle. Molecular genetic studies have revealed that deletions in CDKN2A occur frequently in cancer. Although p16 (INK4a) may be involved in tumor progression, the clinical impact and prognostic implications in head and neck squamous cell carcinoma (HNSCC) are controversial. The o

12. M2-polarized macrophages promote metastatic behavior of Lewis lung carcinoma cells by inducing vascular endothelial growth factor-C expression
OBJECTIVES: Tumor-associated macrophages that generally exhibit an alternatively activated (M2) phenotype have been linked to tumor progression and metastasis. However, the role of M2-polarized macrophages in the growth and metastasis of lung adenocarcinoma remains enigmatic. The aim of this study was to explore the effect of M2 macrophages on the proliferat
