Meta AnalysisCapecitabine-based chemotherapy for metastatic colorectal cancer.
Metastatic colorectal cancer (MCRC) remains a significant public health concern. The objectives of present study are to investigate the efficacy and safety profile of capecitabine-based chemotherapy in the treatment of MCRC. ⋯ Capecitabine-based chemotherapy demonstrated a significantly superior progression-free survival, equivalent overall survival, and comparable response rate with 5-fluorouracil-based chemotherapy. These observations support the use of capecitabine-based chemotherapy in the treatment of MCRC as a first-line or as a neoadjuvant modality.

Prognostic factors and treatment options in patients with leptomeningeal metastases of different primary tumors: a retrospective analysis.
Leptomeningeal metastases (LM) are associated with very poor prognosis and data on outcome are limited. We evaluated prognostic factors and treatment options in patients (pts) with LM of different malignancies in a single center experience. ⋯ In patients with LM an age >50, performance status ≤70%, interval between diagnosis of primary tumor and LM ≤12 months, primary tumor (lung cancer, malignant melanoma) and lack of cytologic response present negative prognostic factors. Systemic chemotherapy is significantly associated with longer survival time than local treatment modalities.

Analysis of related factors associated with radiation pneumonitis in patients with locally advanced non-small-cell lung cancer treated with three-dimensional conformal radiotherapy.
To investigate the correlation among DVH (lung dose-volume histogram) parameters, clinical factors, and grade > or = 2 radiation pneumonitis (RP) in patients with locally advanced non-small-cell lung cancer (NSCLC) treated with three-dimensional conformal radiotherapy (3D-CRT), and the differences between patients treated with 3D-CRT alone or that combined with chemotherapy on RP. ⋯ The comprehensive values of DVH parameters, chemotherapy, and gender have independent effects on the occurrence of RP. Most of DVH parameters were associated with the occurrence of RP. The curve shape composed of multiple points in DVH parameters was more important than any single DVH parameter.

Comparative StudyA new staging system is more discriminant than conventional staging systems for unresectable hepatocellular carcinoma.
Prediction of the life expectancy of a patient with unresectable hepatocellular carcinoma (HCC) remains difficult. The aims of the study were to construct a new staging scheme for patients with unresectable HCC and to compare the discriminatory ability of the staging scheme with the Okuda and CLIP score and TNM staging system in a cohort of patients with unresectable HCC. ⋯ The new staging system, accounting for both liver function and tumor characteristics, can accurately identify patients with different prognoses, particularly in the advanced phases of HCC. It should be useful as the only tool that can be applied for patients with unresectable HCC.

Population alterations of L-arginase- and inducible nitric oxide synthase-expressed CD11b+/CD14⁻/CD15+/CD33+ myeloid-derived suppressor cells and CD8+ T lymphocytes in patients with advanced-stage non-small cell lung cancer.
Immune aberrations have been demonstrated in tumorogenesis, and myeloid-derived suppressor cells (MDSC) have shown to play a pivotal role in mediating immune suppression in animal models of human tumors. In the present study, we explored the clinical relevance of CD11b+/CD14⁻/CD15+/CD33+ MDSCs and the association of MDSCs with CD8+ cytotoxic T lymphocytes in patients with non-small-cell lung cancer (NSCLC). ⋯ Our study provided evidence of an increased pool of CD11b+/CD14⁻/CD15+/CD33+ MDSCs in the peripheral blood of NSCLC patients. For the suppressive effect of the cells on CD8+ T lymphocytes, these findings suggest the important role of the CD11b+/CD14⁻/CD15+/CD33+ MDSCs in mediating immunosuppression in NSCLC.
