Expression and function of erythropoietin receptors in tumors
Authors: Sinclair Angus M. , Todd Marque D. , Forsythe Kevin , Knox Susan J. , Elliott Steve , Begley C. Glenn 
Published: June 2007

AbstractSafety concerns surrounding the use of recombinant human erythropoietin (Epo) to treat anemia in cancer patients were raised after 2 recent clinical studies reported a worse survival outcome in patients who received epoetin α or epoetin β compared with patients who received placebo. Although those findings contrasted with previous clinical studies, which demonstrated no difference in survival for cancer patients who received erythropoiesis‐stimulating agents (ESAs), some investigators have suggested a potential role for ESAs in promoting tumor growth through 1) stimulation of Epo receptors (EpoR) expressed in tumors, 2) stimulation and formation of tumor vessels, and/or 3) enhanced tumor oxygenation. The first and second hypotheses appeared to be supported by some EpoR expression and ESA in vitro studies. However, these conclusions have been challenged because of poor specificity of EpoR‐detection methodologies, conflicting data from different groups, and the lack of correlation between in vitro data and in vivo findings in animal tumor models. For this report, the authors reviewed the biology of EpoR in erythropoiesis and compared and contrasted the reported findings on the role of ESAs and EpoR in tumors.

AbstractBACKGROUND.Metastasis to the breast is rare, but it must be considered in the differential diagnosis of a breast mass. The purpose of this study was to identify clinical characteristics and outcomes associated with this entity to identify determinants of survival.METHODS.Between 1983 and 1998, 169 patients were confirmed by pathology to have metastasis to the breast from nonbreast solid organ primary tumors at University of Texas M. D. Anderson Cancer Center. Medical records were retrospectively reviewed for clinicopathological characteristics. Survival was determined by Kaplan‐Meier analysis.RESULTS.The median age was 51 years (range, 13–85). One hundred forty‐nine (88.2%) patients had a prior history of cancer. Ninety‐one (53.9%) patients presented with additional systemic metastases. The most common histology identified was melanoma (65 patients, 38.5%). In most patients (77%), the diagnosis was initially made through physical examination. The median survival from the time the breast metastasis was diagnosed was 10 months (range, 0.4–192.7). On univariate analysis, a significantly better survival was observed in patients who had no evidence of other disease at the time of diagnosis (P = .0036), patients with neuroendocrine tumors (P = .023), and patients who underwent surgical resection for breast metastases (P = .0001). On multivariate analysis, patients who did not have surgery were 88% more likely to die than those who did (P < 0.001).CONCLUSIONS.Expected survival with metastasis to the breast is poor, therefore, local therapy should be tailored to each individual. The association between overall survival and surgical resection of metastases to the breast should be further investigated. Cancer 2007; 110:731–7. © 2007 American Cancer Society.

AbstractBACKGROUND.The purpose was to evaluate the prognostic factors and treatment outcome of Indian patients with primary diffuse large B‐cell lymphoma (DLBCL) of the tonsil treated at a single institution.METHODS.In all, 121 patients with DLBCL of the tonsil, treated at the Tata Memorial Hospital, Mumbai, India, from January 1990 to December 2002, were included. The median age was 45 years and the majority of patients (68%) were males. Systemic symptoms were present in 12% of patients; 28% presented with stage I and 67% had stage II disease. Treatment consisted of a combination of chemotherapy (CTh) and radiotherapy (RT) for the majority of patients (69.4%). Among those receiving RT, 64% received an RT dose of ≥45 Gy.RESULTS.After a median follow‐up of 62 months, disease‐free survival (DFS) and overall survival (OS) were 66.4% and 81.6%, respectively. Significant prognostic factors included: WHO performance score ≥2 (OS: 72.1% vs 95.6%, P = .016), bulky tumors (OS: 68.5% vs 86.9%, P = .001), presence of B‐symptoms (OS: 36.7% vs 79.6%, P < .001), and Ann Arbor stage. On multivariate analysis; WHO performance score ≥2 (hazard ratio [HR], 4.27; 95% confidence interval [CI], 1.20–15.12), and B symptoms (HR, 6.27; 95% CI, 2.38–16.48), retained statistical significance. CTh + RT resulted in a significantly better outcome than those treated with CTh alone (OS: 85.7% vs 70.7%, P = .008). The complete response (P = .053), DFS (P = .039), and OS (P = .014) rates were significantly better for patients receiving an RT dose ≥45 Gy.CONCLUSIONS.Tumor bulk, WHO performance score, the presence of B symptoms, and Ann Arbor stage significantly influence outcome. A combined modality treatment, consisting of CTh and RT (with an RT dose of ≥45 Gy), results in a satisfactory outcome in patients with this uncommon neoplasm.

Inhibitory effect of meloxicam, a selective cyclooxygenase‐2 inhibitor, and ciglitazone, a peroxisome proliferator‐activated receptor gamma ligand, on the growth of human ovarian cancers
Authors: Xin Bing , Yokoyama Yoshihito , Shigeto Tatsuhiko , Futagami Masayuki , Mizunuma Hideki 
Published: June 2007

AbstractBACKGROUND.It was recently reported that high expression of peroxisome proliferator‐activated receptor γ (PPARγ) and low expression of cyclooxygenase‐2 (COX‐2) might be involved in the inhibition of ovarian tumor progression and confirmed that PPARγ activation could suppress COX‐2 expression via the nuclear factor‐κB pathway in ovarian cancer cells.METHODS.The current study investigated whether meloxicam, a selective COX‐2 inhibitor, and ciglitazone, a ligand for PPARγ, inhibit the growth of human ovarian cancer cell lines and aimed to elucidate the molecular mechanism of their antitumor effect. Tumor growth and survival were examined in female nu/nu mice xenografted with subcutaneous OVCAR‐3 tumors or with intraperitoneal DISS tumors and treated with meloxicam (162 ppm in diet, every day) or ciglitazone (15 mg/kg intraperitoneally once a week).RESULTS.Both meloxicam and ciglitazone treatments significantly suppressed the growth of OVCAR‐3 tumors xenotransplanted subcutaneously and significantly prolonged the survival of mice with malignant ascites derived from DISS cells as compared with controls. Meloxicam treatment decreased COX‐2 expression in tumors by 2.5‐fold compared with that observed in untreated tumors. Although ciglitazone treatment did not alter COX‐2 expression in tumors, it reduced the expression of microsomal prostaglandin (PG) E synthase, which converts COX‐derived PGH2 to PGE2. Both meloxicam and ciglitazone decreased PGE2 levels in serum as well as in ascites. Reduced microvessel density and induced apoptosis were found in solid OVCAR‐3 tumors treated with either meloxicam or ciglitazone.CONCLUSIONS.These results indicate that both meloxicam and ciglitazone produce antitumor effects against ovarian cancer in conjunction with reduced angiogenesis and induction of apoptosis.
