    INTRODUCTION: Adult onset Still's disease is a chronic multisystemic inflammatory disorder characterized by high spiking fever, polyarthralgia and rash. Lymphadenopathy is a prominent feature of adult onset Still's disease and is seen in about 65% of patients. Searching the medical literature using the MEDLINE database from January 1966 through November 2007 we could only find two reported cases of adult onset Still's disease that had progressed to lymphoma. CASE PRESENTATION: We describe a woman who was diagnosed with adult onset Still's disease and developed lymphoma 10 months after the onset of her symptoms. She initially presented with fever and arthritis of the knees, ankles and shoulders, along with a nonpruritic skin rash, myalgia and weight loss. On physical examination she was found to have several enlarged anterior cervical lymph nodes and left posterior auricular lymph nodes all of which were non-tender, immobile and rubbery. Excisional biopsy of the cervical lymph nodes was negative for malignancy. Bone marrow biopsy was also negative for malignancy. She was treated with prednisone. She remained in good health until she presented 10 months later with low back pain, dyspnea and weight loss. Work up revealed malignant lymphoma. She was treated with chemotherapy and was doing well until she presented with abdominal pain. Work up revealed a cirrhotic liver and ascites. She then passed away from hepatorenal syndrome 13 years after the diagnosis of lymphoma. To our knowledge, this is the third reported case of such an occurrence. CONCLUSION: Although the association between adult onset Still's disease and lymphoma has been rarely reported, careful screening for this malignancy in patients suspected to have adult onset Still's disease is warranted

    Small Cell Lung Cancer Doubling Time and its Effect on Clinical Presentation: A Concise Review

    Get PDF
    Small cell lung cancer (SCLC) is one of many types rapidly growing malignant diseases, such as Burkitt’s lymphoma and testicular germ cell cancers. At present, there is no reliable way to screen for SCLC, and imaging modalities tend to be delayed in detecting this type of cancer. The clinical presentation of acutely and rapidly growing SCLC can mimic those of pulmonary inflammatory or infectious disorders, and in some instances, this delays appropriate management and negatively affects patient outcome

    Serotonin Pathway in Cancer

    No full text
    Serotonin (5-hydroxytryptamine, 5-HT) is a biogenic monoamine produced from the essential amino acid tryptophan. Serotonin’s role as a neurotransmitter in the central nervous system and a motility mediator in the gastrointestinal tract has been well defined, and its function in tumorigenesis in various cancers (gliomas, carcinoids, and carcinomas) is being studied. Many studies have shown a potential stimulatory effect of serotonin on cancer cell proliferation, invasion, dissemination, and tumor angiogenesis. Although the underlying mechanism is complex, it is proposed that serotonin levels in the tumor and its interaction with specific receptor subtypes are associated with disease progression. This review article describes serotonin’s role in cancer pathogenesis and the utility of the serotonin pathway as a potential therapeutic target in cancer treatment. Octreotide, an inhibitor of serotonin release, is used in well-differentiated neuroendocrine cancers, and the tryptophan hydroxylase (TPH) inhibitor, telotristat, is currently being investigated in clinical trials to treat patients with metastatic neuroendocrine tumors and advanced cholangiocarcinoma. Several in vitro studies have shown the anticancer effect of 5-HT receptor antagonists in various cancers such as prostate cancer, breast cancer, urinary bladder, colorectal cancer, carcinoid, and small-cell lung cancer. More in vivo studies are needed to assess serotonin’s role in cancer and its potential use as an anticancer therapeutic target. Serotonin is also being evaluated for its immunoregulatory properties, and studies have shown its potential anti-inflammatory effect. Therefore, it would be of interest to explore the combination of serotonin antagonists with immunotherapy in the future

    Is VEGF a predictive biomarker to anti-angiogenic therapy?

    No full text
    Tumor growth and metastasis are dependent on angiogenesis. Inhibiting angiogenesis has therapeutic potentials for treating cancer. Researchers have identified many of the pathways involved in angiogenesis and proposed selective targeted strategies. A high probability of benefit is desirable to justify the choice of anti-angiogenic therapy from an ever-expanding list of expensive new anticancer agents. However, biomarkers of response to anti-angiogenic agents are inconclusive for predicting benefit from these drugs. This paper reviews the most important biomarker of angiogenesis, namely VEGF, in relation to its expression in cancer and the treatment of these cancers through targeting VEGF and its pathways. © 2010 Elsevier Ireland Ltd.SCOPUS: re.jinfo:eu-repo/semantics/publishe

    Predictors of Outcome in Patients With Fibrolamellar Carcinoma: Analysis of the National Cancer Database

    No full text
    Background: Fibrolamellar carcinoma (FLC) is a very rare liver tumor. We aimed to retrospectively analyze the clinicopathological factors and treatment modalities affecting overall survival (OS) in FLC. The objective of the study was to identify predictors of survival in FLC. Patients and methods: Using the National Cancer Database, we identified 496 patients diagnosed with FLC between 2004 and 2015. Clinicopathological, treatment, and survival data were collected. Results: Hepatic resection was performed on 254 (51.2%) patients, liver-directed therapy on 13 (2.6%) patients, and liver transplantation on 15 (3.0%) patients. Median OS by stage were 142.1, 87.2, 32.3, and 14.1 months for stages 1, 2, 3, and 4, respectively. Metastatectomy was not associated with superior median OS (23.4 vs. 10.5 months, p=0.163). Age ≤40, low Charlson-Deyo comorbidity score, early stage and hepatic resection were independently associated with longer OS. Conclusion: Our study reports current trends in FLC management, and identifies independent predictors of OS

    Hypoxia-inducible factor in cancer angiogenesis: structure, regulation and clinical perspectives.

    No full text
    Tumor hypoxia is a common feature of many cancers. A master regulator of hypoxic response is the transcription factor hypoxia-inducible factor-1 (HIF-1). It functions as a master regulator of oxygen and undergoes conformational changes in response to varying oxygen concentrations. In this paper, we review what has been described about HIF-1: its structure, its regulation and target genes, its role in cancer, and its implication for cancer therapy.Journal ArticleReviewinfo:eu-repo/semantics/publishe

    Treatment of metastatic breast cancer: state-of-the-art, subtypes and perspectives.

    Current treatment of metastatic breast cancer (MBC) aims at achieving meaningful clinical responses, improved quality of life, long-term remissions, prolonged survival, and dares to hope for a cure in a small percentage of cases. This article will discuss both consensus and controversies in the management of MBC in the context of the new evolving breast cancer molecular classification. Hormonal therapy remains the mainstay of management of MBC Luminal A and B. Data is emerging on management of ErbB2-positive HR-positive MBC by combining hormonal manipulation and targeted anti-ErbB2 therapy and has recently received regulatory approval in Europe and USA. The optimal use and duration of single agent or combination chemotherapy is discussed. Data and controversies surrounding the use of newer agents such as nab-paclitaxel, ixabepilone, eribulin, and PARP inhibitors as well as trastuzumab is reviewed. Better understanding of pathophysiology has paved the way for the introduction of newer anti-ErbB2 agents such as lapatinib, pertuzumab, T-DM1 and neratinib. Controversies regarding bevacizumab and anti-angiogenesis are discussed. Bisphosphonates have significantly reduced skeletal related events and made significant improvements in the quality of life of patients with MBC. Newer anti-RANK Ligand antibodies show promising results. Significant advances in the understanding of molecular biology of breast cancer have been made and should lead to an improvement in the outcome of MBC. More possibilities of cure can become an attainable goal in the near future.Journal ArticleReviewSCOPUS: re.jinfo:eu-repo/semantics/publishe
