Malignant glioma is one of the most lethal adult cancers, yet its etiology remains largely unknown. We conducted a prospective serum metabolomic analysis of glioma based on 64 cases and 64 matched controls selected from Alpha-Tocopherol, Beta-Carotene Cancer Prevention (ATBC) Study. Median time from collection of baseline fasting serum to diagnosis was nine years (inter-decile range 3-20 years). LC/MS-MS identified 730 known metabolites, and conditional logistic regression models estimated odds ratios for one-standard deviation differences in log-metabolite signals...

Malignant transformation of giant cell tumor of bone (GCTB) without radiotherapy exposure is exceptionally rare, occurring in less than 1% of GCTBs. The safety and efficacy of denosumab in patients with GCTB was recently reported. We herein report a case of a benign recurrent GCTB with an H3F3A mutation that underwent secondary malignant transformation during treatment with denosumab. A 29-year-old woman underwent curettage of a GCTB of the left ischium in 2005. Ten years after the first surgery, the GCTB recurred locally...

BACKGROUND: Long-term data collection is a challenging task in the domain of medical research. Many effects in medicine require long periods of time to become traceable e.g. the development of secondary malignancies based on a given radiotherapeutic treatment of the primary disease. Nevertheless, long-term studies often suffer from an initial lack of available information, thus disallowing a standardized approach for their approval by the ethics committee. This is due to several factors, such as the lack of existing case report forms or an explorative research approach in which data elements may change over time...

BACKGROUND: Dysregulated DNA repair and cell proliferation controls are essential driving forces in mammary tumorigenesis. BCCIP was originally identified as a BRCA2 and CDKN1A interacting protein that has been implicated in maintenance of genomic stability, cell cycle regulation, and microtubule dynamics. The aims of this study were to determine whether BCCIP deficiency contributes to mammary tumorigenesis, especially for a subset of breast cancers with 53BP1 abnormality, and to reveal the mechanistic implications of BCCIP in breast cancer interventions...

Context: Testicular germ cell tumors (GCT) are highly curable. A multidisciplinary approach, including cisplatin-based chemotherapy has resulted in cure in the majority of patients with GCT. Thus, the life expectancy of survivors will extend to many decades post diagnosis. Late treatment toxicities associated with cisplatin-based chemotherapy may impact their future health. Objective: To systematically evaluate evidence regarding the long-term toxicity of cisplatin in GCT survivors...

PURPOSE OF REVIEW: Overview of neuroendocrine neoplasms in the context of their associations with primary and secondary immunodeficiency states. RECENT FINDINGS: Malignancies of neuroendocrine origin are well known to be associated with hereditary syndromes, including multiple endocrine neoplasia type 1, von Hippel-Lindau syndrome, neurofibromatosis type 1, and tuberous sclerosis. This review includes the X-linked form of hyper-IgM syndrome (XHIGM), due to mutations in the CD40Ligand gene (CD40LG), as an additional inherited disorder with susceptibility to such malignancies, and discusses neuroendocrine tumors (NETs) arising in other immunocompromised states...

Metastatic disease is the leading cause of death among cancer patients and involves a complex and inefficient process. Every step of the metastatic process can be rate limiting and is influenced by non-malignant host cells interacting with the tumor cell. Over a century ago, experiments first indicated a link between the immune system and metastasis. This phenomenon, called concomitant immunity, indicates that the primary tumor induces an immune response, which may not be sufficient to destroy the primary tumor, but prevents the growth of a secondary tumor or metastases...

BACKGROUND: Implantable cardioverter defibrillators (ICD) are capable of effectively terminating malignant ventricular arrhythmia and are the most effective way to prevent sudden cardiac death. However, some evidences demonstrated that both anti-tachycardia pacing (ATP) and ICD shock can also bring adverse prognosis. CASE PRESENTATION: A 66-year-old Han Chinese man with prior ICD implantation was admitted to our hospital because of frequent ICD shocks. Although intravenous amiodarone and esmolol succinate were administered daily, the patient suffered 155 episodes of VT/VF during 8 weeks after implantation...

Angiosarcomas are highly malignant and rare tumors of vascular or lymphatic endothelial cell origin with a poor prognosis. Lymphangiosarcoma associated with chronic lymphedema is known as Stewart-Treves syndrome. Stewart-Treves syndrome is primarily described in patients with lymphedema of an upper extremity occurring after breast cancer surgery including radical axillary lymph node dissection and subsequent radiotherapy. It is rarely described in the presence of idiopathic chronic lymphedema of the lower extremities...

Chronic lymphocytic leukaemia (CLL) is a non-Hodgkin lymphoma commonly occurring in older adults. Many people with CLL can go for years without requiring treatment. However, they have an increased risk of secondary cancers, specifically melanoma and non-melanoma skin cancers. Furthermore, these secondary cancers are frequently more aggressive in this cohort of patients. Health professionals working in haematology, dermatology and general practice have an opportunity to educate patients about risk factors and measures to aid prevention...

INTRODUCTION: Currently, there is no agreement regarding if it would be necessary to perform an axillary lymph node dissection (ALND) in patients who have macrometastases in the sentinel lymph node (SLN). We studied the utility of the secondary node analysis (SN), defined as the following node after the SLN in an anatomical and lymphatic pathway, as a sign of malignant axillary involvement. METHODS: An observational, retrospective and multicentre study was designed to assess the utility of the SN as a sign of axillary involvement...

Treatment of patients with relapsed or refractory lymphoma may require allogenic hematopoietic stem cell transplant (HSCT), but treatment of post-transplant relapse disease remains very challenging. Donor lymphocyte infusion and blinatumomab have been used with limited success for the treatment of relapse. Initial data on donor-derived CAR T cells has shown this modality to be safe and highly effective in various hematological malignancies. We present a case of a patient with highly refractory, transformed follicular lymphoma who failed both autologous and allogenic HSCT...

INTRODUCTION: Gastric lipomas are unusual benign lesions and account for less than 1% of all tumours of the stomach and 5% of all gastrointestinal lipomas (Thompson et al.2003; Fernandez et al. 1983 [1,2]). Although predominantly asymptomatic and indolent; they may present with gastric outlet obstruction and upper gastrointestinal (GI) bleeding owing to size and ulceration. Only a few cases have been reported, presenting large in size with massive GI bleeding (Alcalde Escribano et al...

Mucinous carcinomas of the periorbital area are very rare malignant tumors and can be primary or secondary to metastasis. Primary mucinous carcinomas of the eyelid include, most commonly, primary cutaneous mucinous carcinoma with endocrine mucin-producing sweat gland carcinoma being a remote second.[1,2,3,4] To our knowledge, primary mucinous carcinomas of conjunctiva or lacrimal gland elements have not been described in the literature.[5,6] Metastatic carcinoma from visceral sites should also be considered in the differential diagnosis...

STUDY OBJECTIVE: Intravenous immunoglobulin (IVIG) is a weight-based therapy used to treat and prevent infections in patients with hematologic malignancies. Traditionally, IVIG doses have been calculated using actual body weight (ABW). However, limited pharmacokinetic (PK) data suggest dosing strategies using ideal body weight (IBW) or adjusted body weight (adjBW) may be appropriate given the small volume of distribution of IVIG. The objective of this study was to compare the effectiveness of using a precision-dosing strategy (IBW or adjBW) to a traditional-dosing strategy (ABW) for IVIG in patients with hematologic malignancies or those undergoing hematopoietic stem cell transplant, as well as to perform an IVIG drug use analysis...
