The Glasgow Prognostic Score Predicts Response to Chemotherapy in Patients with Metastatic Breast Cancer.

PURPOSE: Breast cancer is one of the most common causes of cancer death in women worldwide. The Glasgow Prognostic Score (GPS), a cumulative prognostic score based on C-reactive protein and albumin, indicates the presence of a systemic inflammatory response. The GPS has been adopted as a powerful prognostic tool for patients with various types of malignant tumors, including breast cancer. The aim of this study was to assess the value of the GPS in predicting the response and toxicity in breast cancer patients treated with chemotherapy. PATIENTS AND METHODS: Patients with metastatic breast cancers in a progressive stage for consideration of chemotherapy were eligible. The clinical characteristics and demographics were recorded. The GPS was calculated before the onset of chemotherapy. Data on the response to chemotherapy and progression-free survival (PFS) were also collected. Objective tumor responses were evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST). Toxicities were graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTC) version 3.0 throughout therapy. RESULTS: In total, 106 breast cancer patients were recruited. The GPS was associated with the response rate (p = 0.05), the clinical benefit rate (p = 0.03), and PFS (p = 0.005). The GPS was the only independent predictor of PFS (p = 0.005). The GPS was significantly associated with neutropenia, thrombocytopenia, anorexia, nausea and vomiting, fatigue, and mucositis (p = 0.05-0.001). CONCLUSIONS: Our data demonstrate that GPS assessment is associated with poor clinical outcomes and severe chemotherapy-related toxicities in patients with metastatic breast cancer who have undergone chemotherapy, without any specific indication regarding the type of chemotherapy applied.

Clinical studies on the treatment of cancer cachexia with megestrol acetate plus thalidomide.

BACKGROUND: The management of cancer-related anorexia/cachexia syndrome (CACS) is a great challenge in clinical practice. To date, practice guidelines for the prevention and treatment of CACS are lacking. The authors conducted a randomized study to confirm the effectiveness and safety of treatment of CACS utilizing megestrol acetate (MA) plus thalidomide. METHODS: One hundred and two candidates with CACS were randomly assigned to two treatment groups (trial group and control group): the trial group received MA (160 mg po, bid) plus thalidomide (50 mg po, bid), while the control group received MA (160 mg po, bid) alone. Treatment duration was 8 weeks. RESULTS: Analysis of the trial group demonstrated a significant increase from baseline in body weight (<0.01), quality of life (p = 0.02), appetite (p = 0.01), and grip strength (p = 0.01), and a significant decrease in fatigue, Glasgow Prognostic Score (p = 0.05), Eastern Cooperative Oncology Group performance status (p = 0.03), IL-6 (p < 0.01), and tumor necrosis factor-α (p = 0.02). In contrast, in the control group, endpoints with a significant improvement from baseline included body weight (p < 0.02) and appetite (p = 0.02). The mean changes in the endpoints from baseline in the trial group were significantly greater compared with the control group: in the primary endpoints, body weight (p = 0.05), fatigue (p < 0.01) and quality of life (p = 0.01), and in the secondary endpoints, grip strength (p = 0.05), Glasgow Prognostic Score (p = 0.02), Eastern Cooperative Oncology Group performance status (p = 0.02), IL-6 (p < 0.01) and tumor necrosis factor-α (p = 0.01). Toxicity was found to be relatively negligible in both groups. CONCLUSION: A combination regimen of MA and thalidomide is more effective than MA alone in the treatment of CACS.

[Dynamic monitoring of graft-versus-host disease after allogeneic peripheral blood stem cell transplantation by soluble HLA-I antigen detection].

OBJECTIVE: To assess the value of dynamic monitoring of soluble human lymphocytic antigen-I (sHLA-I) in the prediction of graft-versus-host disease (GVHD) after allogeneic peripheral blood stem cell transplantation (PBSCT). METHOD: Sandwich enzyme-linked immunosorbent assay (ELISA) was used to quantitatively detect serum sHLA-I. The serum samples for testing were added into W6 32 monoclonal antibody-coated microtiter plate and incubated with anti-beta2m HRP followed by color development with the addition of the substrate. Serum sHLA-I level was measured in 63 healthy blood donors of Shanghai and in 24 PBSCT recipients before and and at different time points after the operation. RESULT: No changes in sHLA-I levels occurred in allogeneic PBSCT recipients without GVHD or with only grade I GVHD, but sHLA-I reached high levels in patients suffering GVHD II-IV(P<0.05), which was effectively lowered by the application of immunosuppressants. CONCLUSION: Measurements of sHLA-I levels can be valuable for monitoring GVHD after PBSCT.

[Migration and distribution of allogeneic T lymphocytes in organs of graft-versus-host disease mouse model].

This study was aimed to investigate the migration and distribution processes of allogeneic donor T lymphocytes in the organs of recipient mice. GVHD model was established by transfusion of the splenocytes of eGFP transgeneic C57BL/6 mice together with born marrow cells harvested from C57BL/6 mice into BALB/c mice underwent 8.0 Gy total body irradiation. The migration and homing of eGFP(+) cells were tracked by stereo-fluorescent microscopy or inverted fluorescent microscopy and flow cytometry. The enzyme linked immunosorbent assay (ELISA) was performed on supernatants from the tissue homogenates to detect the amount of MIP-1alpha. The results indicated that GVHD clinical manifestation and pathological changes of organs appeared on day 8 post transplantation. eGFP-positive donor T cells in recipient organs were observed by inverted fluorescence microscope in frozen section, or by stereo-fluorescence microscopy in living organs, such as liver, spleen, skin, lungs, bowels, and tongue. The highest expression of MIP-1alpha was on day 7 post transplantation in the liver (491.3 +/- 32.1 pg/ml), and day 3 post transplantation in the spleen (881.5 +/- 45.2 pg/ml), respectively (P < 0.05). It is concluded that GVHD was induced by splenocytes of eGFP transgeneic C57BL/6 mice. eGFP(+) cells in the organs can be observed by fluorescent microscopy. In this GVHD model, donor T cells proliferate and infiltrate in liver, skin, bowels, as well as lungs and tongue. MIP-1alpha may be in relation with the infiltration of T lymphocytes in liver and spleen.
