Differential impact of obesity and diabetes mellitus on survival after liver resection for colorectal cancer metastases.

Background: Data on the potential effect of obesity and diabetes mellitus on survival after liver resection due to colorectal cancer (CRC) metastases are very limited.

Methods: Patients undergoing liver resection for CRC metastases in a European institution in 2004-2011 were retrospectively enrolled. Relevant data, such as body mass index, extent of resection, chemotherapy, and perioperative outcome, were collected from medical records.

Comparison of doses and NTCP to risk organs with enhanced inspiration gating and free breathing for left-sided breast cancer radiotherapy using the AAA algorithm.

Background: The purpose of this study was to investigate the potential dose reduction to the heart, left anterior descending (LAD) coronary artery and the ipsilateral lung for patients treated with tangential and locoregional radiotherapy for left-sided breast cancer with enhanced inspiration gating (EIG) compared to free breathing (FB) using the AAA algorithm. The radiobiological implication of such dose sparing was also investigated.

Methods: Thirty-two patients, who received tangential or locoregional adjuvant radiotherapy with EIG for left-sided breast cancer, were retrospectively enrolled in this study.

Expression of caspase-3 predicts prognosis in advanced noncardia gastric cancer.

There is strong evidence that tumor growth is not only a result of uncontrolled cell proliferation but also of decreased apoptosis. Caspase-3 is a member of interleukin-1 beta-converting enzyme which is involved in the induction of apoptosis. Data on the expression of caspase-3 in patients with gastric cancer and its association with patient outcome are somewhat contradictory.

Chemotherapy ± cetuximab modulates peripheral immune responses in metastatic colorectal cancer.

Objective: To identify changes in peripheral immune responses in patients with metastatic colorectal cancer (mCRC) treated with irinotecan/5-fluorouracil/leucovorin (IFL) alone or in combination with cetuximab (C-IFL).

Methods: Peripheral blood mononuclear cells (PBMCs) collected from healthy donors (n = 20) and patients with mCRC receiving treatment with either IFL (n = 30) or C-IFL (n = 30) were tested for cytokine production upon polyclonal stimulation with anti-CD3 monoclonal antibody, T cell proliferation in the autologous mixed lymphocyte reaction (auto-MLR) and T regulatory cell (Treg) frequency. The respective results were evaluated over two treatment cycles and further assessed in relation to response to treatment.

Neurotoxicity caused by the treatment with platinum analogues.

Platinum agents (cisplatin, carboplatin, and oxaliplatin) are a class of chemotherapy agents that have a broad spectrum of activity against several solid tumors. Toxicity to the peripheral nervous system is the major dose-limiting toxicity of at least some of the platinum drugs of clinical interest. Among the platinum compounds in clinical use, cisplatin is the most neurotoxic, inducing mainly sensory neuropathy of the upper and lower extremities.
