Lymph-node ratio is an independent prognostic factor in patients with stage III colorectal cancer: a retrospective study from the Middle East.

Background: In this retrospective study, we evaluated the prognostic effect of positive lymph-node ratio (pLNR) on patients with stage III colorectal cancer (CRC). Our paper is the first analysis, to our knowledge, to deal with such data from the Middle East.

Methods: We analyzed the clinicopathological data of 535 patients diagnosed with colorectal cancer at our institution between 1983 and 2003.

Safety and Efficacy of Sorafenib in Patients with Hepatocellular Carcinoma (HCC) and Child-Pugh A versus B Cirrhosis.

Background: We performed a retrospective analysis of data from a phase II study evaluating sorafenib in patients with advanced hepatocellular carcinoma (HCC) to assess differences in safety and efficacy based on Child-Pugh (CP) status (A/B).

Methods: Patients received sorafenib 400 mg PO bid. We analyzed safety, pharmacokinetic (PK), and efficacy data in the two CP groups.

Clinical roundtable monograph. Integrating recent data in managing adverse events in the treatment of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a major cause of cancer-related morbidity and mortality worldwide. In the United States, HCC is the main cause of death in patients with cirrhosis, and the incidence of this malignancy is on the rise. Because HCC is associated with a particularly poor prognosis, emphasis is placed on surveillance of high-risk patients.

PR-104 plus sorafenib in patients with advanced hepatocellular carcinoma.

Purpose: PR-104 is activated by reductases under hypoxia or by aldo-keto reductase 1C3 (AKR1C3) to form cytotoxic nitrogen mustards. Hepatocellular carcinoma (HCC) displays extensive hypoxia and expresses AKR1C3. This study evaluated the safety and efficacy of PR-104 plus sorafenib in HCC.

A Cancer and Leukemia Group B phase II study of sunitinib malate in patients with previously treated metastatic pancreatic adenocarcinoma (CALGB 80603).

Background: The Cancer and Leukemia Group B (CALGB) conducted a phase II study evaluating sunitinib in patients with progressive metastatic pancreas adenocarcinoma following prior gemcitabine-based therapy (trial CALGB 80603; ClinicalTrials.gov identifier, NCT00397787). The primary endpoint was to determine the disease control rate (DCR) as measured by the Response Evaluation Criteria in Solid Tumors (complete response, partial response [PR], and stable disease) at 6 weeks.

Gastrointestinal cancer educational case series: management of metastatic adenocarcinoma of unknown primary origin in a Ph+ ALL survivor.

Introduction: Secondary malignancies and chronic end-organ sequelae are significant and steadily rising consequences of cancer therapy. The workup and management of a carcinoma of unknown primary must consider the patient's clinical presentation, radiologic and pathologic findings, and comorbidities.

Case Report: We present the case of a 50-year-old female survivor of Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) with significant treatment-related end-organ sequelae who developed a metastatic adenocarcinoma of unknown primary 15 years following curative therapy for her ALL.

Doxorubicin plus sorafenib vs doxorubicin alone in patients with advanced hepatocellular carcinoma: a randomized trial.

Context: In a randomized phase 3 trial, 400 mg of sorafenib twice daily prolonged overall survival of patients with advanced hepatocellular carcinoma (HCC) and Child-Pugh A disease. In a phase 1 study, sorafenib combined with doxorubicin, 60 mg/m(2), was well tolerated by patients with refractory solid tumors. The combination of sorafenib and doxorubicin in patients with advanced HCC has not been evaluated in a phase 2 or 3 trial.

Integrating recent data in managing adverse events in the treatment of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a major cause of cancer-related morbidity and mortality worldwide. In the United States, HCC is the main cause of death in patients with cirrhosis, and the incidence of this malignancy is on the rise. Because HCC is associated with a particularly poor prognosis, emphasis is placed on surveillance of high-risk patients.

Targeting mutated K-ras in pancreatic adenocarcinoma using an adjuvant vaccine.

Purpose: Codon 12 mutations of K-ras are frequent in pancreatic adenocarcinoma, and represent potential tumor-specific neoantigens. The objective of this study was to assess the safety and efficacy of immunizing patients with resected pancreatic cancer with a vaccine targeted against their tumor-specific K-ras mutation.

Methods: Patients with resected pancreatic cancer, with K-ras mutations at codon 12, were vaccinated once monthly for 3 months with a 21-mer peptide vaccine containing the corresponding K-ras mutation of the patient's tumor.

Nonoperative therapies for combined modality treatment of hepatocellular cancer: expert consensus statement.

Although surgical resection and liver transplantation are the only treatment modalities that enable prolonged survival in patients with hepatocellular carcinoma (HCC), the majority of HCC patients presents with advanced disease and do not undergo resective or ablative therapy. Transarterial chemoembolization (TACE) is indicated in intermediate/advanced stage unresectable HCC even in the setting of portal vein involvement (excluding main portal vein). Sorafenib has been shown to improve survival of patients with advanced HCC in two controlled randomized trials.

Gastrointestinal cancer educational case series: the history and management of complex cases in gi oncology. A 72 year-old man with metastatic gastric cancer.

Introduction: Gastric cancer is the third most common cancer worldwide and the second leading cause of cancer deaths. Appropriate staging and treatment options relate to the stage of disease and performance status of the patient.

Case Report: Here we present the case of a 72 year old male, with an initial presentation of apparently locally advanced gastric cancer.

Advanced hepatocellular carcinoma: which staging systems best predict prognosis?

Purpose: The purpose of cancer staging systems is to accurately predict patient prognosis. The outcome of advanced hepatocellular carcinoma (HCC) depends on both the cancer stage and the extent of liver dysfunction. Many staging systems that include both aspects have been developed.

Pancreatic islet cell carcinoma presenting with concurrent Cushing's and Zollinger-Ellison syndromes: case series and literature review.

Cushing's syndrome and Zollinger-Ellison syndrome occur occasionally as a result of neuroendocrine cancers. The concurrence of the two syndromes has been considered to confer a poor clinical and therapeutic outcome. In this study, we are reviewing two patients with pancreatic islet cell carcinomas and with both Zollinger-Ellison and Cushing's syndromes, one followed up for more than 5 years, and the other still receiving therapy, 5 years since diagnosis.

Hepatocellular carcinoma in two patients with cardiac cirrhosis.

Hepatocellular carcinoma has been commonly associated with multiple etiologic factors including hepatitis B and C, alcoholic liver disease, and more rarely congenital metabolic liver diseases. 'Cardiac cirrhosis' is the cirrhosis resulting from prolonged passive liver venous congestion secondary to right-sided congestive heart failure; hepatocellular carcinoma is a rarely reported outcome. In this study we present two female patients with congenital heart defects treated with the Fontan procedure who survived into their third decade, and developed hepatocellular carcinoma in the setting of cardiac cirrhosis.

Selection of patients with hepatocellular carcinoma for sorafenib.

Sorafenib, a multitargeted anti-VEGF receptor and raf kinase inhibitor, was recently approved by the FDA for treating unresectable hepatocellular carcinoma (HCC) based on 2 randomized phase III studies. In addition, a phase II study evaluating sorafenib in patients with HCC and Child-Pugh A and B and a phase I study evaluating sorafenib in patients with organ dysfunction have provided insight about the safety and efficacy of sorafenib in patients with HCC and more advanced cirrhosis, and any difference in outcome based on etiology of HCC. The lack of objective responses observed in the sorafenib arm in the SHARP study also raises practical issues about how to assess response or efficacy of the therapy and thus how long a patient should receive sorafenib.

Indications for neoadjuvant, adjuvant, and palliative chemotherapy in the treatment of biliary tract cancers.

Advanced biliary tract carcinomas represent a group of aggressive diseases that still carries a poor prognosis. Chemotherapy has been shown to provide disease control and may also prolong survival. An established role for systemic therapy in the adjuvant setting is still lacking.
