BACKGROUND: Increasing evidence supports the hypothesis that chronic and persistent inflammation contributes to cancer development. However, the molecular mechanisms that lead to cancer in chronic inflammation and the role of angiogenesis in inflammation-associated cancer remain poorly understood. METHODS: NINETY PATIENTS WERE ENROLLED: 30 cases of CHC without cirrhosis, 28 cases of CHC with liver cirrhosis, and 32 cases of HCC and hepatitis C virus infection. Ten wedge liver biopsies, taken during laparoscopic cholecystectomy, served as normal controls...

BACKGROUND: Gallbladder cancer (GBC) carries an unfavorable prognosis with high mortality. This retrospective study was conducted to identify prognostic factors after resection of GBC, to assist in selecting appropriate surgical and adjuvant therapy. METHODS: Sixty-two patients from two institutions were identified with GBC by pathology. In 25, the cancer was unresectable at presentation. The remaining 37 patients comprised the study population. Log-rank analysis was used to assess univariate association with disease-free survival (DFS) and disease-specific survival (DSS)...

BACKGROUND: Octreotide LAR is indicated for treatment of malignant carcinoid syndrome and has been studied at doses of 10 to 30 mg intramuscularly every 4 weeks. In clinical practice, higher doses are often prescribed for patients who experience refractory carcinoid syndrome (flushing and/or diarrhea) or tumor growth while on the maximum label-recommended dose. METHODS: We performed a retrospective, longitudinal review of octreotide LAR administration at a tertiary institution to determine the frequency of above-label dosing and outcomes...

BACKGROUND: Adenosquamous carcinoma of the pancreas (ASCAP) is a rare histologic type of pancreatic carcinoma that constitutes 1% to 4% of all pancreatic exocrine malignancies. It has a clinical presentation similar to that of adenocarcinoma of the pancreas (ACP), but may have a worse overall prognosis, with most patients surviving for less than 2 years. METHODS: This was an institutional, retrospective, cohort analysis of 237 patients who underwent resection of pancreatic cancer with curative intent...

BACKGROUND: Many chemotherapeutic regimens used to treat colorectal cancer (CRC), including 5-fluorouracil plus leucovorin in combination with irinotecan (FOLFIRI) or oxaliplatin (FOLFOX), are administered on an every-other-week (q2w) dosing schedule. Chemotherapy in combination with a monoclonal antibody (mAb) directed toward the epidermal growth factor receptor (EGFR) has emerged as an effective treatment option. There are currently 2 anti-EGFR mAbs approved by the United States Food and Drug Administration: cetuximab and panitumumab...

PURPOSE: We compared our institutional experience using 3D conformal radiation therapy (3DCRT) vs. IMRT (intensity-modulated radiation therapy) for anal cancer. METHODS: We performed a single-institution retrospective review of all patients with squamous cell carcinoma anal cancer treated from September 2000 through September 2011, using definitive chemoradiation with curative intent. RESULTS: This study included 89 consecutive patients (37 3DCRT, 52 IMRT)...
