In this report, we describe a case of malignant prolactinoma with liver metastases masquerading as metastatic gastrointestinal stromal tumor (GIST). A 54–years–old woman received dopamine agonists for macroprolactinoma for 2 years, followed by transsphenoidal surgery due to a poor response to medical therapy. Despite the continuation of dopamine agonist after surgery, serum prolactin level progressively increased to above 8,000 ng/ml in 5 years. There was no evidence of disease recurrence on sella magnetic resonance imaging (MRI). She stopped medical therapy. Meanwhile, she was diagnosed with GIST accompanied b...

CONCLUSIONS: We provide a comprehensive analysis of both clinical and pathological findings of the largest cohort of patients operated on for pituitary adenomas in one tertiary reference center. To the best of our knowledge, this is the largest up-to-date published analysis in our country. PMID: 32154573 [PubMed - as supplied by publisher]

Our data suggest that pituitary tumor transforming gene 1 (PTTG1) plays a vital role in inflammation ‐related hepatocellular carcinoma (HCC) via c‐myc induction and that PTTG1 may be a potential therapeutic target for HCC. AbstractHepatocellular carcinoma (HCC) is a malignant disease caused by a variety of factors. However, the genomic and molecular aberrations in HCC are largely unknown. Herein,pituitary tumor transforming gene 1 (PTTG1) was discovered as a potential inflammation ‐related oncogene in HCC, and its functions and molecular mechanisms were investigated. mRNA expression microarray, real‐time polymerase...

Conclusions This review describes how leukocyte-heparanase can be a double-edged sword in tumor progression; it can enhance tumor immune surveillance and tumor cell clearance, but also promote tumor survival and growth. We also discuss the potential of using heparanase in leukocyte therapies against tumors, and the effects of heparanase inhibitors on tumor progression and immunity. We are just beginning to understand the influence of heparanase on a pro/anti-tumor immune response, and there are still many questions to answer. How do the pro/anti-tumorigenic effects of heparanase differ across different cancer types? Does...

Conclusions: This is a unique presentation of a pituitary tumor, displaying characteristics of both clinically silent corticotropic and “atypical” macroadenoma subtypes. Although initially ACTH positive while clinically silent, the patient’s disease ultimately recurred metastatically with manifestations of Cushing’s disease and psychosis. With the addition of temozolomide to her treatment plan, her primary and metastatic sit es have responded favorably to radiation therapy. Thus, the addition of temozolomide may be beneficial in the treatment of aggressive pituitary tumors.Case Rep Oncol 2019;12:139 –146

Conclusion: Combination treatment with ipilimumab and nivolumab may be an effective treatment in pituitary carcinoma. Clinical sequencing of pituitary tumors that have relapsed following treatment with conventional chemotherapy may identify the development of therapy-induced somatic hypermutation, which may be associated with treatment response to immunotherapy.

Abstract Metronidazole is a synthetic derivative of nitroimidazole that has been widely used for the treatment of several bacterial and protozoal parasitic infections including trichomoniasis, amoebiasis, giardiasis, liver abscess, acute ulcerative gingivitis, syphilis and tropical phagedena. In addition to its toxicity in the gastrointestinal tract and central/peripheral nervous system, metronidazole has been reported to cause mucosal imbalance by affecting the expression of mucin (Muc2 gene), which is responsible to form an insoluble mucous barrier that protects the gut lumen from microbial colonization. Since m...

Conclusions RT/TMZ was safely delivered and might provide sustained control of extraneural metastases in PC. Although this retrospective report has limitations, RT/TMZ can be considered as a therapeutic option for the management of extraneural metastases in PC.
