[Paraneoplastic Leukocytosis and Thrombocytosis as Prognostic Biomarkers in Non-small Cell Lung Cancer].

Background And Objectives: Search for inexpensive laboratory markers have identified associations between blood counts and lung cancer outcomes. In this study, we evaluated the prognostic value of paraneoplastic leukocytosis (p-Leukocytosis) and paraneoplastic thrombocytosis (p-Thrombocytosis) in patients with non-small cell lung cancer (NSCLC). We also studied their relation to the expression of commonly detected molecular markers.

Adjuvant chemotherapy is associated with improved survival in patients with stage II colon cancer.

Background: The role of adjuvant chemotherapy in patients with stage II colon cancer remains to be elucidated and its use varies between patients and institutions. Currently, clinical guidelines suggest discussing adjuvant chemotherapy for patients with high-risk stage II disease in the absence of conclusive randomized controlled trial data. To further investigate this relationship, the objective of the current study was to determine whether an association exists between overall survival (OS) and adjuvant chemotherapy in patients stratified by age and pathological risk features.

A brief yoga intervention implemented during chemotherapy: A randomized controlled pilot study.

Objectives: Fatigue and other treatment-related symptoms (e.g., sleep disturbance) are critical targets for improving quality of life in patients undergoing chemotherapy.

Phase II trial of adjuvant oral thalidomide following cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal surface disease from colorectal/appendiceal cancer.

Purpose: This phase II single-institution trial of adjuvant thalidomide after cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for patients with appendiceal and colorectal malignancies sought to detect an improvement in progression-free survival (PFS) from 7 to 12 months.

Methods: Eligible patients received CS, HIPEC, and baseline imaging, followed by pretreatment thalidomide counseling. All participants were then started on a 28-day regimen of thalidomide, 100 mg by mouth at bedtime, followed by 200 mg for 4 weeks, followed by 300 mg as the final maintenance dose, as tolerated.

Oncologic management of hereditary colorectal cancer.

Colorectal cancer (CRC) is the second most common cancer in females and the third most common cancer diagnosed in males. Familial CRC comprises ~20 to 30% of all CRC cases. Lynch syndrome (LS), previously called hereditary nonpolyposis CRC (HNPCC), is the most common of the hereditary CRC syndromes.

A randomized phase II study of immunization with dendritic cells modified with poxvectors encoding CEA and MUC1 compared with the same poxvectors plus GM-CSF for resected metastatic colorectal cancer.

Objective: To determine whether 1 of 2 vaccines based on dendritic cells (DCs) and poxvectors encoding CEA (carcinoembryonic antigen) and MUC1 (PANVAC) would lengthen survival in patients with resected metastases of colorectal cancer (CRC).

Background: Recurrences after complete resections of metastatic CRC remain frequent. Immune responses to CRC are associated with fewer recurrences, suggesting a role for cancer vaccines as adjuvant therapy.

Optimal timing of systemic therapy in resectable colorectal liver metastases.

Perioperative chemotherapy has been shown to improve disease-free survival compared with surgery alone for resectable colorectal liver metastases (CLM). We examined our experience with systemic chemotherapy in this clinical setting. A prospectively collected liver surgery database identified 210 patients treated for resectable CLM from 1996 to 2010.

A randomized pilot phase I study of modified carcinoembryonic antigen (CEA) peptide (CAP1-6D)/montanide/GM-CSF-vaccine in patients with pancreatic adenocarcinoma.

Background: CEA is expressed in >90% of pancreatic cancers (PC) and may be an appropriate immunotherapy target. CEA is poorly immunogenic due to immune tolerance; CAP1-6D, an altered peptide ligand can help bypass tolerance. We conducted a pilot randomized phase I trial in PC patients to determine the peptide dose required to induce an optimal CD8(+) T cell response.

Reverse translation of phase I biomarker findings links the activity of angiotensin-(1-7) to repression of hypoxia inducible factor-1α in vascular sarcomas.

Background: In a phase I study of angiotensin-(1-7) [Ang-(1-7)], clinical benefit was associated with reduction in plasma placental growth factor (PlGF) concentrations. The current study examines Ang-(1-7) induced changes in biomarkers according to cancer type and investigates mechanisms of action engaged in vitro.

Methods: Plasma biomarkers were measured prior to Ang-(1-7) administration as well as 1, 2, 3, 4, and 6 hours after treatment.

A two-cohort phase I study of weekly oxaliplatin and gemcitabine, then oxaliplatin, gemcitabine, and erlotinib during radiotherapy for unresectable pancreatic carcinoma.

Objectives: Gemcitabine is a potent radiosensitizer. When combined with standard radiotherapy (XRT) the gemcitabine dose must be reduced to about 10% of its conventional dose. Oxaliplatin and erlotinib also have radiosensitizing properties.

The effect of targeted agents on outcomes in patients with brain metastases from renal cell carcinoma treated with Gamma Knife surgery.

Object: Gamma Knife surgery (GKS) has been reported as an effective modality for treating brain metastases from renal cell carcinoma (RCC). The authors aimed to determine if targeted agents such as tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors, and bevacizumab affect the patterns of failure of RCC after GKS.

Methods: Between 1999 and 2010, 61 patients with brain metastases from RCC were treated with GKS.

The current landscape of locally advanced rectal cancer.

Postoperative adjuvant chemoradiotherapy was recommended as the standard treatment for patients with rectal cancer because it reduces local recurrence. This paradigm shifted with the use of neoadjuvant chemoradiotherapy, which not only reduces local recurrence but also improves sphincter preservation and surgical outcomes. However, the treatment of rectal carcinoma remains complicated.

A phase II study of capecitabine, oxaliplatin, bevacizumab and cetuximab in the treatment of metastatic colorectal cancer.

Aim: This study was designed to determine the efficacy and tolerability of capecitabine, oxaliplatin and bevacizumab in combination with cetuximab as first-line therapy for advanced colorectal cancer.

Patients And Methods: Patients with previously untreated advanced colorectal cancer received oxaliplatin 130 mg/m² and bevacizumab 7.5 mg/kg every three weeks, capecitabine 850 mg/m² twice daily on days 1-14, and cetuximab at 400 mg/m² load and 250 mg/m² weekly.

Outcomes of patients with esophageal cancer staged with [¹⁸F]fluorodeoxyglucose positron emission tomography (FDG-PET): can postchemoradiotherapy FDG-PET predict the utility of resection?

Purpose: To determine whether [(18)F]fluorodeoxyglucose positron emission tomography (FDG-PET) can delineate patients with esophageal cancer who may not benefit from esophagectomy after chemoradiotherapy.

Patients And Methods: We reviewed records of 163 patients with histologically confirmed stage I to IVA esophageal cancer receiving chemoradiotherapy with or without resection with curative intent. All patients received surgical evaluation.

Arsenic trioxide in patients with adenocarcinoma of the pancreas refractory to gemcitabine: a phase II trial of the University of Chicago Phase II Consortium.

Objectives: There is no effective therapy for patients with metastatic pancreatic cancer who fail initial therapy with gemcitabine. Arsenic trioxide has potent antiproliferative and proapoptotic effects in pancreatic cancer cell lines. We conducted a multicenter phase II trial in patients with advanced pancreatic cancer who experienced disease progression on or after a gemcitabine-containing regimen.

Targeted agents and esophageal cancer--the next step?

Esophageal cancer (EC) is an aggressive cancer and is a leading cause of cancer-related death worldwide. In the United States and Western Europe, there has been a decline in the incidence of squamous cell carcinomas coupled with a rapid rise in incidence of adenocarcinoma of the esophagus and gastroesophageal junction. Although the 5-year survival rates have slowly increased over time from 4% to 14%, the outcomes are still dismal.
