    Mostafa Paridar , Omid Kiani Ghalesardi , Mohammad Seghatoleslami , Ahmad Ahmadzadeh , Abbas Khosravi , Najmaldin Saki
    Myelodysplastic syndromes (MDS) include a heterogeneous group of blood disorders generally afflicting older people. Several genetic factors have been reported from these patients that have an important role in the diagnosis, prognosis, and treatment of this disease. BCR-ABL1 is a genetic factor that has occasionally been reported in some studies. This review attempts to characterize MDS patients reported to harbor this fusion and to assess the diagnostic, therapeutic, and prognostic potential of BCR-ABL1 fusionin MDS patients. This review showed that BCR-ABL fusion has been reported in 22...

    Alkaline phosphatase flare with hyperostosis of bone metastases in lung adenocarcinoma treated with gefitinib

    Hiroto Kaneko , Kazuho Shimura , Yosuke Matsumoto , Mihoko Yoshida , Masafumi Taniwaki , Junya Kuroda
    Alkaline phosphatase (ALP) flare has been reported to occur during cancer treatment as a favorable event, particularly in the presence of bone metastasis. There have been only a few reports in lung cancer and associated radiographic findings have seldom been described. The authors observed ALP flare in a female patient with lung adenocarcinoma soon after the initiation of gefitinib. Moreover, on computed tomography, metastatic lesions of the rib and thoracic spine showed marked hyperostosis, with sizes larger than the original bone structure, suggesting efficacy of gefitinib. The...

    Profiling of circulating tumor cells in liquid biopsies from metastatic cancer patients

    Pravin D. Potdar , Keerti Sen
    Aim: Circulating tumor cells (CTCs) are crucial to tumor metastasis and valuable for prediction of clinical outcome in patients with solid tumors. Here, the authors aimed to establish a method for enumeration and characterization of CTCs from liquid biopsies. Methods: Peripheral blood mononuclear cells (PBMCs) were separated from blood samples from patients with metastatic cancer using Ficoll-Hypaque gradients and cultured to isolate and enumerate CTCs. Cultured CTCs were morphologically characterized by light and phase contrast microscopy. The tumorigenicity of Ficoll-Hypaque-separated...

    Targeting Toll-like receptors against cancer

    Bing Du , Qiu-Li Jiang , Joseph Cleveland , Bing-Rong Liu , Dekai Zhang
    The discovery of Toll-like receptors (TLRs) about 20 years ago was a remarkable achievement not only in the field of immunology but also in the field of medicine. The TLRs are a family of pattern recognition receptors which play an important role in immune responses by recognizing pathogen-associated molecular patterns. The TLRs also recognize danger-associated molecular patterns, which are associated with some diseases such as cancer. Recent evidence shows that TLRs are expressed not only in immune cells but also in tumor cells. The TLRs appear to play a role in tumor progression and...

    The significance and clinical utility of the detection of primary malignant circulating prostate cells: a review of the evidence

    Nigel P. Murray
    Primary malignant circulating prostate cells (CPCs) are those detected in blood before definitive treatment for prostate cancer. CPCs can be detected in men with benign prostate disease; however, some methods to distinguish between benign and malignant prostate cells have to be validated. This study presents a review of the subject, including theoretical considerations for the selection of markers to detect them, the different methods used, and the utility of their detection in identifying men with prostate cancer and as a prognostic factor.

    Insights into mechanisms of tumor dissemination from circulating tumor cell lines of small cell lung cancer

    Gerhard Hamilton , Barbara Rath
    Despite the fact that the majority of cancer patients succumb to metastatic disease, most aspects of tumor metastasis are not understood in detail at present. Cell biologic steps of dissemination are difficult to characterize in human tumors and research is in large part confined to cell line and experimental animal studies. Epithelial-mesenchymal transition (EMT), intravasation of malignant cells, dissemination as circulating tumor cells (CTCs) and eventually mesenchymal-epithelial transition (MET) at distal sites are steps believed to be involved in metastasis. Small cell lung cancer...

    Squamous cell carcinoma of tongue 18 years after renal transplantation: a case report

    Jyoti Poddar , Ashutosh Das Sharma , Ubrangala Suryanarayana Kunikullaya
    Solid organ transplant recipients are at increased risk of developing malignancies, even decades after transplant, due to the prolonged use of immunosuppressant drugs. A 35-year-old male underwent renal transplant for end stage renal disease 18 years previously and was on immunosuppressive drugs since that time and was on regular follow up. In 2016, he developed a squamous cell carcinoma of tongue, which was operated and adjuvant radiation therapy was given. The patient is currently on follow up and asymptomatic. Though squamous cell carcinoma of tongue is a relatively common malignancy in...

    Nanocarrier drugs in the treatment of brain tumors

    Tereza Cerna , Marie Stiborova , Vojtech Adam , Rene Kizek , Tomas Eckschlager
    Nanoparticle-mediated targeted delivery of drugs might significantly reduce the dosage and optimize their release properties, increase specificity and bioavailability, improve shelf life, and reduce toxicity. Some nanodrugs are able to overcome the blood-brain barrier that is an obstacle to treatment of brain tumors. Vessels in tumors have abnormal architecture and are highly permeable; moreover, tumors also have poor lymphatic drainage, allowing for accumulation of macromolecules greater than approximately 40 kDa within the tumor microenvironment. Nanoparticles exploit this feature, known...

    Metastatic clostridial myonecrosis secondary to perforated metastatic bowel cancer

    Nasser Mohammed Amer , John Karayanis
    Spontaneous metastatic clostridial myonecrosis is a rare condition caused by Clostridium septicum. The underlying lesion is usually either a colonic neoplasm or leukemia. The authors reported a 67-year-old female who presented with acute abdomen secondary to a perforated sigmoid cancer and who developed gas gangrene in her right leg. Unfortunately, despite all resuscitative measures, she died. The authors reviewed the literature; the diagnosis of metastatic myonecrosis was based on a high index of suspicion, development of bullae containing gram-positive rods, and subcutaneous crepitus...

    Isolated breast metastasis mimicking as second primary cancer - a case report

    Manjari Shah , Umang Mithal , Sandeep Agarwal , Sweety Gupta , Disha Tiwari , Shashank Srinivasan , Asheesh Jain , Ritu Chandra
    Primary carcinoma of breast is common but breast is a rare site of metastasis and metastases from extramammary sites are even rarer. Metastasis to breast from rectal carcinoma is very unusual and till now 19 cases of breast secondaries from colorectal carcinoma have been reported in literature which include 14 cases where the primary site was colon and remaining 5 were from the rectum. Here the authors report a case of adenocarcinoma anorectum who had completed treatment and after 4 months developed a lump in her left breast which was metastatic. Metastatic lesions of breast are usually...

    A small solitary fibrous tumor of the bladder

    Guido Petracco , Carlo Patriarca
    The authors present a case of histologically benign and incidentally discovered millimetric solitary fibrous tumor of the bladder, invisible to radiologic imaging and clinically benign. The case came to our attention because of repeated episodes of renal colic. As opposed to the present case, solitary fibrous tumor are generally discovered when they reach certain dimensions, being slow-growing, painless masses. Such a tumor of the bladder is a very rare finding, with less than 20 cases reported, and it has yet to be described with such a small size. The main differential diagnoses are...
