Amifostin in protection of kidney from cisplatinum injury / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate Amifostin's effect on protecting kidney from cisplatinum (DDP) injury and its adverse reactions and safety.</p><p><b>METHODS</b>193 Patients were divided into two groups randomly: 102 in group A (treatment group) and 91 in group B (control group). Indexes such as blood routine, blood calcium, liver function, blood urea nitrogen (BUN), cretinine (C), and urinary N-acetyl-beta-D-glucosaminidase (NAG)/C and micro-albumin (MAB/C) were monitored at different intervals before or after treatment.</p><p><b>RESULTS</b>In the two courses of treatment in both groups, the deviation (D) values of MAB/C before treatment and on D2 in group A were lower than those in grop B (P < 0.05), so were those before treatment and on D4, D6, D10 and D14 (P < 0.01). The D-values of NAG/C before treatment and on D4, D6, D10 and D14 in the first course of group A were obviously lower than those on the corresponding days in group B (P < 0.01), so were those before treatment and on D2, D4, D6, D10 and D14 in the second course (P < 0.01).</p><p><b>CONCLUSION</b>The reduction of MAB/C and NAG/C by Amifostin in group A demonstrates that: Amifostin is able to effectively protect the renal function, regardless of the type of tumor. In contrast with group B, Amifostin in group A shows no protection for tumor in lung cancer and ovarian cancer. The main side effects of Amifostin are mild hypotension, nausea, vomiting and hypocalcemia in some patients.</p>

Clinical study on the bone marrow micrometastases in patients with non-small cell lung cancer by immunohistochemical techniques / 中国肺癌杂志

<p><b>BACKGROUND</b>To investigate the immunohistochemical detected method and the clinical incidence of the bone marrow micrometastases (BMM) in patients with non-small cell lung cancer (NSCLC) and to analyze the sensitivity and specificity and clinical application value.</p><p><b>METHODS</b>Bone marrow samples were collected from the anterior superior iliac spines or posterior superior iliac spines of 53 patients with NSCLC in clinical stage I to III and 15 patients in stage IV, and the BMM was detected by immunohistochemical techniques (IHC) using monoclonal antibodies AE1/AE3 against cytokeratin. Chi-square test was used statistically.</p><p><b>RESULTS</b>The IHC sensitivity could be 10⁻⁵. The BMM positive rate was 22.6% (12/53) in stage I to III and 53.3% (8/15) in stage IV, and there was a significant difference in the BMM positive rate between stage I to III and stage IV (P < 0.05). No correlation was observed between BMM and sex, age, KPS, pathology classification and cancer cell differentiation.</p><p><b>CONCLUSIONS</b>The detection of BMM by IHC is convenient, sensitive, and specific. It might be helpful to diagnose bone marrow micrometastasis in patients with NSCLC.</p>
