pyrazinamide, isoniazide, 6-mercaptopurine and 5-flurouracil may also result in pellagra like syndromes. Pyrazinamide and isonicotinic acid hydrazide (INH) are structural analogues of niacin and can depress endogenous niacin production by feedback inhibition or substrate competition. INH impairs the functioning of pyridoxine, a cofactor in tryptophan-niacin pathway and inhibits the niacin synth...

BACKGROUND The oral multi-kinase inhibitor sunitinib malate improves the survival of patients with gastrointestinal stromal tumors (GIST) after the disease progresses or intolerance to imatinib mesylate develops. Urinary fistulae arising during treatment with sunitinib for GIST have not been described. CASE PRESENTATION We describe a 62-year-old female patient diagnosed with unresectable GIST...

Limited progress has been made in the treatment of advanced pancreatic cancer. Gemcitabine was established as a standard of care after a randomized phase III study showed an improvement in clinical benefit response and overall survival over 5-flurouracil. Multiple phase III studies have been conducted to improve upon the response and survival established with single-agent gemcitabine. Combining...

Objective: To evaluate the cytotoxic and genotoxic activity of Euphorbia triaculeata Forssk. plant extract from Jazan region, Saudi Arabia, in an in vitro cancer model, which could be beneficial in anticancer therapy against human breast cancer cell line (MCF-7), prostate cell line (PC-3), human hepatocellular carcinoma cell line (HEPG2) and normal breast epithelial cell line (MCF-10A). The hum...

Neuroendocrine carcinoma (NEC) is a rare tumor, comprising < 1% of stomach cancers. A 55-year-old woman was referred to our hospital with biopsy-proven gastric cancer. A shallow ulcerative lesion was detected in the lesser curvature of the lower body. It was suspected to be early gastric cancer IIA + IIC type. Thus, endoscopic submucosal dissection was performed. She was subsequently diagnosed ...

Epithelioid hemangioendothelioma (EHAE) is a malignant vascular tumor derived from endothelial cell often misdiagnosed as Hepatic carcinoma on the basis of radiological features. Till now etiology of this rare curiosity is unknown but it is related with use of oral contraceptives pills (OCP), liver trauma, exposure to vinyl chloride and hepatitis. We herein report on a case which failed to be d...

In this study, we have demonstrated that Korean Panax ginseng (KG) significantly enhances myelopoiesis in vitro and reconstitutes bone marrow after 5-flurouracil-induced (5FU) myelosuppression in mice. KG promoted total white blood cell, lymphocyte, neutrophil and platelet counts and improved body weight, spleen weight, and thymus weight. The number of CFU-GM in bone marrow cells of mice and se...

A 50 year old gentleman presented to our surgical outpatient department with two years history of bleeding per rectum with off and on lower abdominal pain. He was pale, lethargic and emaciated. On digital rectal examination, hard fungating cauliflower like growth was found at anorectal junction. Systemic examination revealed no significant findings. Laboratory investigations showed Hb l0gm/dI. ...

PURPOSE Although the combination of irinotecan and 5-Fluorouracil is clinically active, it is associated with significant toxicity and resistance. Studies were carried out to define the optimal dosage, sequence, and timing for the combination in mice bearing xenografted human tumors. EXPERIMENTAL DESIGN The maximum tolerated dose of irinotecan and 5-Fluorouracil in combination was determined ...

Oesophageal adenocarcinoma (OAC) is the sixth most common cause of cancer deaths worldwide, and the 5-year survival rate for patients diagnosed with the disease is approximately 17%. The standard of care for locally advanced disease is neoadjuvant chemotherapy or, more commonly, combined neoadjuvant chemoradiation therapy (neo-CRT) prior to surgery. Unfortunately, ~60-70% of patients will fail ...
