OBJECTIVEThis study was conducted to investigate the correlation between anemia and postoperative chemotherapy in elderly cancer patients.
METHODSOne hundred and fifty-seven elderly patients ( age ≥ 60) with pathologically confirmed breast, lung and digestive tract cancers, who had HGB ≥ 120 g/L and ECOG scores 0-2, were included in this study. We reviewed their clinicopathological data and analyzed the correlation of anemia in breast cancer patients after 1, 3 or 5 cycles and lung cancer patients after 1, 2 or 3 cycles of postoperative chemotherapy.
RESULTSAmong the 157 cases, the overall proportion of anemia was 31.8% (50/157) , with 18.8% in male and 47.2% in female patients (P < 0.001). After three cycles of chemotherapy, the proportion of anemia was 57.9% in lung cancer, 34.5% in breast cancer, 26.3% in gastric cancer and 9.3% in colorectal cancer patients (P < 0.001). The proportion of anemia during 5 cycles chemotherapy (three cycles in lung cancer) was gradually increasing. In the lung cancer patients, anemia was observed in 66.7% of patients who received vinorelbine plus cispiatin regimen and 25.0% of cases who received vinorelbine regimen chemotherapy (P = 0.044).
CONCLUSIONSIn most elderly patients with normal hemoglobin level and in good conditions, the chemotherapy-related anemia is mild and less frequent. Age should not limit the adjuvant chemotherapy in elderly cancer patients. Attention should be paid to the possibility of anemia in elderly female lung cancer patients receiving multiple cycle platinum-based chemotherapy regimens.

Objective To investigate whether HSP90α could be a sensitive and specific serum biomarker for the diagnosis and progression of lung cancer. Methods In the present study, different secretomic analy-ses on the two human lung adenocarcinoma cell lines CL1-0 and CL1-5 with low and high metastatic poten-tial, respectively, were performed using sodium dodecyl sulfate-polyacrylamide gel electrophoresis and ma-trix-assisted laser desorption/ionization time-of-flight mass spectrometry. The candidate biomarker was con-firmed by Western blotting, and was further analyzed in 224 serum samples including 141 lung cancer, 37 benign pulmonary diseases, as well as 46 healthy individuals using ELISA assay. Results HSP90α was sig-nificantly upregulated in the CM of CL1-5 cells. It was found that the levels of HSP90α were specifically ele-vated in the sera of non-small cell lung cancer compared with other groups. At the cut-off point 0.535 on the receiver operating oharacteristie curve, HSP90α could comparatively discriminate lung cancer from benign lung disease and healthy control groups with sensitivity of 0. 817, specificity 0. 919 and total accuracy 80. 14%. Conclusion HSP90α may be a potential useful serum biomarker for discriminating lung cancer from benign lung diseases and healthy individuals and staging of non-small cell lung cancer.
