Neuroblastoma (NB) is the most frequently diagnosed neoplasm during infancy and its incidence declines within the first 3-5 years of life. It can be rarely diagnosed in adolescents and young adults. Adolescents have advanced stage of disease, higher frequency of uncommon metastatic sites such as lungs, and worse outcomes. Herein, we describe an unusual case of NB in a 17-year-old adolescent presented with lung metastasis at diagnosis. The patient was diagnosed with stage IV NB. Thorax high-resolution computed tomography (HRCT) scan revealed irregular septal thickening with ground glass opacity consistent with pulmonary parenchymal metastases...

BACKGROUND/AIM: L-[3-(18)F]-α-methyl tyrosine ((18)F-FAMT) positron emission tomography (PET) has a high specificity for detecting malignant lesions. However, the usefulness of therapeutic monitoring of (18)F-FAMT PET against advanced human neoplasms remains unclear. Here, we evaluated (18)F-FAMT PET clinical significance regarding therapy response and outcome after systemic chemotherapy in patients with advanced lung cancer, compared to (18)F-FDG PET. PATIENTS AND METHODS: All patients with untreated advanced lung cancer received (18)F-FAMT PET and (18)F-FDG PET before and 4 weeks after one cycle of chemotherapy...

Long-term survivors of Hodgkin lymphoma (HL) experience several late adverse effects of treatment, with second malignant neoplasms (SMNs) and cardiovascular diseases (CVDs) being the leading causes of death in these patients. Other late effects have also been identified, such as pulmonary dysfunction, endocrinopathies (thyroid dysfunction, infertility), neck muscle atrophy, and persistent fatigue. HL survivors have two- to fourfold increased risks to develop SMNs and CVD compared with the general population...

Birt-Hogg-Dubé syndrome (BHDS) is an autosomal dominant inherited disorder caused by germline mutations in the FLCN gene, and characterized by skin fibrofolliculomas, multiple lung cysts, spontaneous pneumothorax, and renal neoplasms. Pulmonary manifestations frequently develop earlier than other organ involvements, prompting a diagnosis of BHDS However, the mechanism of lung cyst formation and pathogenesis of pneumothorax have not yet been clarified. Fibroblasts were isolated from lung tissues obtained from patients with BHDS (n = 12) and lung cancer (n = 10) as controls...

OBJECTIVES: Considering the fact that the standardized uptake value (SUV) of a normal lung tissue is expressed as x±SD, x+3×SD could be considered as the threshold value to outline the internal tumor volume (ITV) of a lung neoplasm. METHODS: Three hollow models were filled with 55.0 kBq/mL fluorine-18 fluorodeoxyglucose ((18)F-FDG) to represent tumors. The models were fixed to a barrel filled with 5.9 kBq/mL (18)F-FDG to characterize normal lung tissues as a phantom...

Antoni Castells
Colorectal cancer is one of the most frequent neoplasms in western countries; it is the third most common cancer in men after prostate and lung cancer and the second most common in women after breast cancer. Colorectal cancer is usually sporadic but in a small proportion is hereditary. The genetic cause is well established, allowing pre-symptomatic diagnosis in at-risk relatives. The present article reviews the most novel findings presented at the latest meeting of the American Gastroenterological Association on hereditary forms of colorectal cancer, especially Lynch syndrome and MUTYH-associated polyposis, as well as diverse organisational aspects that can favour the correct management of these patients and their relatives...

Primary leiomyosarcoma arising from the ovarian vein is extremely rare, with only 10 cases reported in the literature. We report on a case of leiomyosarcoma of the left ovarian vein in a 67-year-old woman who presented with abdominal discomfort. Pelvic ultrasound revealed a large, solid, irregular mass in close relation to the left ovary. The patient subsequently underwent a total hysterectomy with bilateral salpingo-oophorectomy. Histologically, the tumor was composed of interlacing fascicles of spindle cells with abundant eosinophilic cytoplasm, hyperchromatic nuclei, and prominent nucleoli...

Confronted with brain metastases (BM), pathologists aim to rule out a primary central nervous system (CNS) tumor and to identify or verify the primary tumor site to guide the clinician to specific therapies. Apart from morphological features, ancillary immunohistochemical analysis is the most effective tool for characterizing a metastatic neoplasm of unknown origin. A limited array of antibodies is used, taking into account relevant clinical information and the known brain tropism of lung cancer, breast cancer and melanoma...

REVIEW
D B Warheit, R Kreiling, L S Levy
The relevance of particle-overload related lung tumors in rats for human risk assessment following chronic inhalation exposures to poorly soluble particulates (PSP) has been a controversial issue for more than three decades. In 1998, an ILSI (International Life Sciences) Working Group of health scientists was convened to address this issue of applicability of experimental study findings of lung neoplasms in rats for lifetime-exposed production workers to PSPs. A full consensus view was not reached by the Workshop participants, although it was generally acknowledged that the findings of lung tumors in rats following chronic inhalation, particle-overload PSP exposures occurred only in rats and no other tested species; and that there was an absence of lung cancers in PSP-exposed production workers...

BACKGROUND: Birt-Hogg-Dubé (BHD) syndrome is a rare inherited autosomal genodermatosis and caused by germline mutation of the folliculin (FLCN) gene, a tumor suppressor gene of which protein product is involved in mechanistic target of rapamycin (mTOR) signaling pathway regulating cell growth and metabolism. Clinical manifestations in BHD syndrome is characterized by fibrofolliculomas of the skin, pulmonary cysts with or without spontaneous pneumothorax, and renal neoplasms. There has been no pulmonary neoplasm reported in BHD syndrome, although the condition is due to deleterious sequence variants in a tumor suppressor gene...

Aggressive digital papillary adenocarcinoma (ADPA) is a rare sweat gland neoplasm with a high recurrence rate and metastatic potential. In this study, the authors describe a case that originally appeared to benign spiradenoma, but took an ominous course eventually resulting in the diagnosis of ADPA. A 73-year-old woman developed a gradually growing nodule on the second toe of her left foot, which she had first noticed 4 years previously. An excisional biopsy was performed followed by histological examination...

Tracheobronchial leiomyoma is a rare pulmonary neoplasm accounting for <2% of benign tumours of the lower airway. Published case series reported bronchoscopic resectability with laser ablation for lesions located in the large airway. Surgery was performed for tumours with wide-based and tumours located in segmental bronchus or lung parenchyma. This is the first reported case of complete bronchoscopic cryoresection of leiomyoma arising from the subsegmental bronchi and illustrating the cryopreservation of its histologic morphology...

OBJECTIVES: Two cases of epithelial-myoepithelial carcinoma are presented, one arising in the pleura and the other in the anterior mediastinum. The cases represent a unique distribution of these tumors within the thoracic cavity. METHODS: Both patients were men aged 25 and 68 years, respectively, who had chest pain and dyspnea. Imaging revealed an anterior mediastinal mass in one patient and a pleural-based tumor in the other. Neither patient had any history of malignancy, and physical examination did not disclose any tumor elsewhere...

Dermatomyositis is an autoimmune inflammatory myopathy associated with dermatologic findings. Its association with neoplasms is widely reported and has been shown to be higher in lung cancer, particularly small-cell carcinoma, probably as it originates from neuroendocrine cell precursors, as well as breast and ovarian cancer. The low frequency of dermatomyositis makes it difficult to suspect the underlying lesions among the diagnostic possibilities of systemic diseases with cutaneous manifestations. Therefore, the high probability of a neoplasm should always be considered, with reports of up to 75% in the eastern population and about 40% in general...

BACKGROUND: Anaplastic lymphoma kinase (ALK) gene rearrangements are oncogenic drivers of non-small-cell lung cancer (NSCLC). Brigatinib (AP26113) is an investigational ALK inhibitor with potent preclinical activity against ALK mutants resistant to crizotinib and other ALK inhibitors. We aimed to assess brigatinib in patients with advanced malignancies, particularly ALK-rearranged NSCLC. METHODS: In this ongoing, single-arm, open-label, phase 1/2 trial, we recruited patients from nine academic hospitals or cancer centres in the USA and Spain...

BACKGROUND: The neoplasm is still a potential threat for breast, Non-Small Cell Lung (NSCL) and cervix cancer patients. Those gradually invade into other body organs, inducing complex pathological complications. Whereas, the anticancer drugs suppress the bone marrow, resulting serious hematological toxicities. Thus, the monocytic toxicity may the chance of infections, particularly in AID's patients. OBJECTIVE: We aimed this retrospective study to investigate the monocytopenia induced by vinorelbine following chemotherapy in cancer patients...

BACKGROUND: Pneumonia is a serious but a preventable stroke complication. Prediction scales for post-stroke pneumonia have been proposed with an intent to improve surveillance and prevention but they remain under-utilized in clinical practice. Most existing scales were developed using both ventilated and non-ventilated patients which may affect their accuracy. We derived and validated a novel, pragmatic scale to predict hospital-acquired pneumonia (HAP) after stroke employing only a non-ventilated stroke cohort...
