PURPOSE: Denosumab reduces the incidence of skeletal-related events (SREs) in solid tumor patients with bone metastases (BM). However, there have been no detailed reports of the efficacy of denosumab in untreated non-squamous non-small cell lung cancer (NSCLC) patients with BM. METHODS: The medical records of patients with untreated non-squamous NSCLC and BM at diagnosis at our institution were reviewed retrospectively. The overall survival (OS) and the time to SREs were analyzed according to the treatment for the BM...

Renal cell carcinoma (RCC) is a common tumor of the urinary tract. It is known to have variable presentations due to the extremely vascular nature of the organ. RCC are known to metastasize to lungs, bone, and brain commonly but atypical metastasis to various sites are reported in literature but as very rare pathology. We report a case of a 60-year-old female who presented with multiple inguinal and axillary lymph node enlargements which on excision biopsy showed metastatic RCC. RCC can present with synchronous metastatic deposits in the various organs...

Thyroid gland is an uncommon site of metastasis, and metastasis to the gland secondary to nasopharyngeal carcinoma is seldom seen. We were only able to identify eight reported cases in the literature. A 61-year-old man, diagnosed case of nasopharyngeal cancer-second primary ( first primary-oropharynx), was found to have a thyroid nodule on routine follow-up positron emission tomography-computed tomography (PET-CT) scan. There was no evidence of metastases at any other sites. The thyroid nodule was confirmed as metastatic carcinoma by fine needle aspiration cytology...

Lung metastasis is the major cause of death in patients with triple negative breast cancer (TNBC), an aggressive subtype of breast cancer with no effective therapy at present. It has been proposed that dual-targeted therapy, ie, targeting chemotherapeutic agents to both tumor vasculature and cancer cells, may offer some advantages. The present work was aimed to develop a dual-targeted synergistic drug combination nanomedicine for the treatment of lung metastases of TNBC. Thus, Arg-Gly-Asp peptide (RGD)-conjugated, doxorubicin (DOX) and mitomycin C (MMC) co-loaded polymer-lipid hybrid nanoparticles (RGD-DMPLN) were prepared and characterized...

BACKGROUND Kaposi sarcoma (KS) is known to involve the mucocutaneous tissues and the aero-digestive tracts. In acquired immune deficiency syndrome (AIDS) patients, KS has an aggressive course and carries poor prognosis. We present a case of pulmonary KS with osseous metastases as the first presentation of human immunodeficiency virus (HIV) infection in a young male. The lesions impressively decreased in size and numbers following initiation of highly active antiretroviral therapy (HAART). CASE REPORT A 34-year-old heterosexual male presented with a one month history of cough and 15-20 pound weight loss within six months...

BACKGROUND: Bone metastases (BMs) occur commonly in patients with metastatic renal cell carcinoma (mRCC). Tyrosine kinase inhibitors (TKIs) have improved the outcomes for patients with mRCC. However, data on the outcomes of mRCC patients with BMs treated with TKIs are limited. We describe the outcomes of patients with BMs treated with TKI therapy and compare them with the outcomes from a pre-TKI group. PATIENTS AND METHODS: Using an institutional tumor registry, a retrospective review of patients with mRCC from 2002 to 2003 and 2006 to 2007 was performed...

Today, in addition to surgery, other local therapies are available for patients with small-size non-small-cell lung cancer (NSCLC) and oligometastatic disease from various cancers. Local therapies include stereotactic ablation radiotherapy (SABR) and thermal ablative therapies through percutaneously inserted applicators. Although radiofrequency ablation (RFA) has been explored in series with several hundreds of patients with pulmonary tumours, investigation of the potential of other ablation technologies including microwave ablation, cryoablation, and irreversible electroporation is ongoing...

BACKGROUND: The skeleton is the most common site of colonization by metastatic cancers. Zoledronic acid (ZA) has been shown to be effective for the treatment of bone metastases regardless of whether the bone lesions are osteolytic or osteoblastic. Biochemical markers of bone turnover may be useful tools to quantify the degree of bone remodeling in the presence of bone metastases. The aim of this work was to establish the correlation between tumor dispersion (bioluminescence) and biochemical markers of bone turnover in two osteolytic and osteoblastic metastasis models in mice...

INTRODUCTION: A potentially resectable bony metastasis in the context of oligometastatic colorectal cancer is uncommon. Bony metastases are usually considered a late event with poor prognosis and generally associated with liver and/or lung metastases. INDEX CASE: A previously healthy 33-year-old gentleman, with no family history of colorectal cancer, presented with rectal bleeding and at colonoscopy had a biopsy-proven adenocarcinoma of the rectum, 7 cm from the anal verge...

Clarithromycin may improve cachexia and survival in non-small cell lung cancer (NSCLC), but adequately controlled data are lacking. This study was undertaken primarily to inform the feasibility and scale of a phase III trial. Eligible consenting patients with stage IV NSCLC and cachexia were to be randomized to receive either clarithromycin 250mg twice daily or placebo for eight weeks. Aspects of trial feasibility recorded included numbers eligible, approached and recruited, together with adherence and completion of treatment and assessments...

Whether bisphosphonates could enhance the effect of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) in non-small-cell lung cancer (NSCLC) patients with EGFR mutation and bone metastases (BM) remains unknown. EGFR mutation status were collected from 1560 patients with NSCLC and BM. 356 NSCLC patients with EGFR mutation and BM were identified. Among them, 91 patients received EGFR-TKIs alone and 105 patients received EGFR-TKIs plus bisphosphonates as first-line therapy. Comparing to TKIs alone, EGFR-TKIs plus bisphosphonates had a statistically significant longer progression-free survival (PFS: 11...

AIMS: Giant cell tumour of bone (GCTB) is a neoplasm predominantly of long bones characterised by the H3F3A mutation G34W. Conventional diagnostic is challenged by the tumour's giant cell-rich morphology, which overlaps with other giant cell containing lesions of the bone. Recently, a monoclonal antibody specific for the H3F3A mutation has been generated. Our aim was to test this antibody on a cohort of giant cell containing lesions. METHODS AND RESULTS: We used the antibody for analysis of 22 H3F3A-mutated GCTB, including two patients with recurrences; for comparison we analysed a cohort of 36 H3F3A-wild-type giant cell-rich lesions of the bone and soft tissue, containing one brown tumour, six aneurysmal bone cysts, six chondroblastomas, five non-ossifying-fibromas, two fibrous dysplasias, nine tenosynovial giant cell tumours, one giant cell-rich sarcoma and six osteosarcomas...

PURPOSE: Small-intestine neuroendocrine neoplasms are heterogeneous neoplasms arising from endocrine cells of the intestinal mucosa. Ki-67 is the main determinant of prognosis in neuroendocrine neoplasms. However, the search for new prognostic makers represents a key point with regard to small-intestine neuroendocrine neoplasms. The oncofetal protein IMP3 plays a role in cell growth and its expression has a prognostic value in lung neoplasms. METHODS: From January 1998 to August 2015, all the consecutive small-intestine neuroendocrine neoplasms patients suitable for surgery were included: 51 patients (32 males, median age 68 years) had small-intestine neuroendocrine neoplasms classified according to the WHO 2010 classification...

Metastasis is the main cause of treatment failure and death in cancer patients. Metastasis of tumor cells to the brain occurs frequently in individuals with breast cancer, non-small cell lung cancer, or melanoma. Despite recent advances in our understanding of the causes and in the treatment of primary tumors, the biological and molecular mechanisms underlying the metastasis of cancer cells to the brain have remained unclear. Metastasizing cancer cells interact with their microenvironment in the brain to establish metastases...

Distant metastases from salivary gland tumors are considered infrequent: the incidence of distant metastases ranges from 24% to 61% according to different histotypes and to the site of the primary mass. The most common site of distant metastases due to salivary gland malignancies is the lung. From the pathology point of view, cytokeratins (CK) are important differentiation markers in salivary gland tumors, which are often used for the diagnostic process. Their employment also may be useful to identify and confirm the diagnosis of their distant metastases...

RATIONALE: The early detection of recurrent differentiated thyroid carcinoma (DTC) cells in postsurgery DTC patients relies on the sensitivity of measuring both the level of thyroglobulin (Tg) and 131-iodine distribution on a whole-body scan (WBS). Recent studies have defined patients who subsequently have no evidence of disease as those who have a stimulated Tg level <1 ng/mL with no other radiological or clinical evidence of disease. PATIENT CONCERNS: A woman patient with solid variant papillary thyroid carcinoma (SVPTC) had undergone twice thyroidectomy with lymph node dissection and radioactive therapy...

BACKGROUND: Pancreatic tumors often represent primary neoplasms, however organ involvement with metastatic disease can occur. The use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) to determine the underlying pathology provides guidance of clinical management. METHODS: 25 cases were identified in a retrospective review of our institution's records from 2006 to 2016. Clinical parameters and prognosis are described. RESULTS: Metastatic lesions to the pancreas diagnosed by EUS-FNA accounted for 4...
