A prospective study of tobacco and alcohol use as risk factors for pharyngeal carcinomas in Singapore Chinese
Authors: Friborg Jeppe T. , Yuan Jian‐Min , Wang Renwei , Koh Woon‐Puay , Lee Hin‐Peng , Yu Mimi C. 
Published: February 2007

AbstractBACKGROUNDNasopharyngeal carcinoma (NPC) is a rare disease in most populations; however, in areas of Southeast Asia and North Africa and in the Arctic, undifferentiated NPC is the most frequent pharyngeal malignancy. Although smoking and alcohol have been established firmly as synergistic risk factors for other pharyngeal carcinomas, previous studies on the association between these risk factors and NPC have not been consistent. Therefore, the authors analyzed this relation in a cohort of Singapore Chinese, which is a population with a high incidence of NPC.METHODSFrom 1993 to 1998, a population‐based cohort of 61,320 Singapore Chinese ages 45 years to 74 years who were free of cancer completed a comprehensive interview on living conditions and dietary and lifestyle factors. By linkage to Singapore population‐based registries, the cohort was followed through 2005, and cancer occurrence was determined. The relative risk of NPC and other oropharyngeal carcinomas in the cohort was investigated by using a Cox proportional hazards model.RESULTSIn total, 173 NPCs and 75 other oropharyngeal carcinomas were observed during 601,879 person‐years of follow‐up. Smoking for >40 years was associated with a doubled risk of NPC (relative risk, 2.0; 95% confidence interval, 1.2–3.3), whereas smoking intensity, age at smoking initiation, and alcohol consumption were not associated with NPC risk. In contrast, smoking duration, smoking intensity, age at smoking initiation, and alcohol consumption all were associated with an increased risk of other oropharyngeal carcinoma (P for trend, <.0001).CONCLUSIONSSmoking and alcohol influenced the risk of NPC and other oropharyngeal carcinomas differently in a high‐incidence NPC population. Long‐term smoking was a risk factor for NPC, but alcohol consumption was not. Cancer 2007. © 2007 American Cancer Society.
Survival advantage with decitabine versus intensive chemotherapy in patients with higher risk myelodysplastic syndrome

AbstractBACKGROUNDDecitabine, a hypomethylating agent, is active and has been approved for the treatment of myelodysplastic syndrome (MDS) and chronic myelomonocytic leukemia. Intensive chemotherapy is an accepted form of therapy for patients with higher risk MDS. The comparative efficacy of these 2 forms of treatment in MDS is unknown. The objective of the current study was to compare the efficacy and toxicity profiles of decitabine and intensive chemotherapy in MDS.METHODSThe authors compared lower intensity decitabine therapy (n = 115 patients) with intensive chemotherapy (as it is used in acute myeloid leukemia [AML]) in patients with higher risk MDS. Two comparisons were made with a cohort of 376 historic patients (from 1995 to 2005): The first comparison included a subcohort of 115 patients (Group A) who matched the 115 decitabine study patients according to age, International Prognostic Scoring System, and cytogenetics; and the second comparison included the whole cohort of 376 patients without matching (Group B). A multivariate analysis was performed for outcome.RESULTSThe complete remission (CR) rate according to AML criteria was 43% with decitabine, 46% with intensive chemotherapy in Group A, and 52% with intensive chemotherapy in Group B. Compared with Group A, mortality at 6 weeks was 3% with decitabine versus 13% with intensive chemotherapy (P = .006) and, at 3 months, 7% with decitabine versus 23% with intensive chemotherapy (P = .001). Survival was better with decitabine versus intensive chemotherapy in Group A (median survival: 22 months vs 12 months; P < .001). A multivariate analysis of survival in all 491 patients who received decitabine or intensive chemotherapy (Group B) selected decitabine as an independent, favorable prognostic factor for survival (P = .006; hazard ratio, 0.74) after accounting for the independent prognostic effect of pretreatment factors.CONCLUSIONSIn this analysis, decitabine was associated with a survival advantage compared with intensive chemotherapy in patients with higher risk MDS. Future studies should evaluate prospectively the results of decitabine versus intensive chemotherapy in this setting. Cancer 2007 © 2007 American Cancer Society.
Overexpressed Raf‐1 and phosphorylated cyclic adenosine 3′‐5′‐monophosphatate response element‐binding protein are early markers for lung adenocarcinoma
Authors: Cekanova Maria , Majidy Mourad , Masi Thomas , Al‐Wadei Hussein A. N. , Schuller Hildegard M. 
Published: February 2007

AbstractBACKGROUNDPulmonary adenocarcinoma (PAC) is the leading type of lung cancer and has a high mortality. The tobacco carcinogen nicotine‐derived nitrosamine 4‐(N‐methyl‐N‐nitrosamino)‐1‐(3‐pyridyl)‐1‐butanone (NNK) stimulates the proliferation of human PAC cells and small airway epithelial cells through β‐1 adrenorecptor‐mediated transactivation of the epidermal growth factor receptor (EGFR).METHODSUsing the NNK hamster PAC model and human PAC tissue arrays with matched and unmatched normal lung tissues, the authors tested the hypothesis that Raf‐1, an effector of the EGFR, and P‐CREB, an effector of the β‐adrenoreceptor, are overexpressed in a significant subset of human PACs and are early markers of PAC development. Western blots from respiratory epithelial cells and microadenomas harvested by laser‐capture microdissection from hamster lungs accompanied by immunostains were used to monitor the expression levels of Raf‐1 and P‐CREB after 5 weeks, 10 weeks, and 20 weeks of NNK treatment. Expression levels of these markers in human PAC tissue arrays were assessed by immunostains. Reverse‐phase proteomics, Western blot analysis, and immunoprecipitation in immortalized human small‐airway epithelial cells and in a human PAC cell line in the presence and absence of dominant‐negative Raf were used to determine Raf dependence of extracellular signal‐regulated kinase 1 and 2 (ERK1/2) activation in response to NNK or isoproterenol.RESULTSThe data showed a time‐dependent increase in the expression of Raf‐1 and P‐CREB after NNK treatment in small‐airway epithelial cells and microadenomas of hamsters. The majority of human lung adenocarcinomas simultaneously overexpressed Raf‐1 and P‐CREB. Dominant‐negative Raf completely abrogated ERK1/2 activation by NNK and isoproterenol.CONCLUSIONSThe current results indicated that RAF‐1 and P‐CREB may contribute to the development of a significant subset of human lung adenocarcinomas and may offer promising targets for early detection and treatment.

AbstractBACKGROUNDPrimary hepatic sarcoma is a rare entity. The objectives of the study were to define treatment and long‐term outcome and to identify prognostic factors.METHODSBetween January 1981 and December 2004, 30 patients with primary sarcoma of the liver and 5 patients with primary carcinosarcoma of the liver were treated. Patient demographics, tumor characteristics, treatment, and actuarial survival were analyzed.RESULTSOf the 30 patients with primary hepatic sarcoma (10 epithelioid hemangioendothelioma, 5 embryonal sarcoma, 5 angiosarcoma, 3 solitary fibrous tumor, and 7 other types), 11 underwent R0‐resection and had a 5‐year disease‐specific survival of 64%. Of these 11 patients, 4 had low‐grade sarcoma and have not developed tumor recurrence. In the group of 7 patients with high‐grade sarcomas who underwent R0‐resection, both patients with angiosarcoma died within 11 months, whereas the 5 patients with embryonal sarcoma had a 5‐year disease‐free and disease‐specific survival of 80%. Six of the 10 patients with an epithelioid hemangioendothelioma were managed without surgery, as they had diffuse, slowly progressing, or stable lesions; these patients had a 5‐year disease‐specific survival of 67%. Of the remaining 13 patients in whom R0‐resection was not performed, there were no 3‐year survivors. The prognosis for patients with primary carcinosarcoma of the liver was poor, with all but 1 patient dying within a year and no 3‐year survivors.CONCLUSIONSThe outcome of patients with primary hepatic sarcoma depends primarily on tumor histology and the ability to achieve complete tumor resection. Improvements in outcome will require the development of more effective systemic therapies. Cancer 2007. © 2007 American Cancer Society.
