  • Background: Lung cancer is one of the most common cancers in the world and a major cause of death from cancer. One of the important indicators to compare the prevalence and incidence of the disease is a change in the trend. The aim of this study was to investigate the changes in the incidence of lung cancer in Iran. Materials and Methods: This study was conducted based on existing data obtained from a national registry of cancer cases and the Disease Management Center of Ministry of Health in Iran. All cases registered in the country were included during 2003-2008. Incidence rates were reported based on the direct method and standard population of World Health Organization. The study also examined the morphology of common lung cancers. Trends in incidence underwent joinpoint regression analysis. Results: Based on the results of this study, 14,403 cases of lung cancer have been recorded of which 10,582 cases were in men and 3,821 in women. Highest incidence rates were observed in the 80-84 age group. Considerable variation across provinces was evident. In females squamous cell carcinoma (SCC) demonstrated a reduction from 24% to 16% of lesions over the period of study, while adenocarcinoma rose from 21% to 29%. In males a similar reduction in SCC was apparent (42% to 29%, again with increase in AC (13 % to 18%). Conclusions: The results show that the increase in the incidence of lung cancer the trend is that more men than women and in men and may be caused by changes in smoking pattern. The incidence of lung cancer in the North West and West provinces was higher than in other regions.

  • Purposes: Lung cancer is prevalent worldwide and improvements in timely and effective diagnosis are need. Pentraxin-3 as a novel serum marker for lung cancer (LC) has not been validated in large cohort studies. The aim of the study was to assess its clinical value in diagnosis and prognosis. Methods: We analyzed serum PTX-3 levels in a total of 1,605 patients with LC, benign lung diseases and healthy controls, as well as 493 non-lung cancer patients including 12 different types of cancers. Preoperative and postoperative data were further assessed in patients undergoing LC resection. The diagnostic performance of PTX-3 for LC and early-stage LC was assessed using receiver operating characteristics (ROC) by comparing with serum carcinoembryonic antigen (CEA), cytokeratin 19 fragments (CYFRA 21-1). Results: Levels of PTX-3 in serum were significantly higher in patients with LC than all controls. ROC curves showed the optimum diagnostic cutoff was 8.03ng/mL (AUC 0.823, [95%CI 0.789-0.856], sensitivity 72.8%, and specificity 77.3% in the test cohort; 0.802, [95%CI 0.762-0.843], sensitivity 69.7%, and specificity 76.4% in the validate cohort). Similar diagnostic performance of PTX-3 was observed for early-stage LC. PTX-3 decreased following surgical resection of LC and increased with tumor recurrence. Significantly elevated PTX-3 levels were also seen in patients with non-lung cancers. Conclusions: The present data revealed that PTX-3 was significantly increased in both tissue and serum samples in LC patients. PTX-3 is a valuable biomarker for LC and improved identification of patients with LC and early-stage LC from those with non-malignant lung diseases.

  • Purpose: Lung cancer, one of the most frequently diagnosed cancers in the world, is characterized by relatively high morbidity and mortality. Berbamine (BER) has been initially reported to exert anti-proliferative effects against a series of cancers. Methods: In this study the in vitro cytotoxicity of BER was measured by MTT assay. In vivo anti-cancer efficacy of BER was assessed in A549 xenografts. Results: Cytotoxicity tests showed dose-dependent cell growth inhibition effects of BER against A549 cells. Moreover, BER significantly reduced the growth of lung cancer in a dose-dependent manner in nude mice with prolonged survival time. Conclusion: Therefore, BER might be in herbal medicine for cancer therapy and further efforts are needed to explore therapeutic strategies.

  • Less than 2% of patients with primary esophageal cancers have synchronous primary lung cancers and many patients with these synchronous tumors are deemed ineligible for radical resection by surgeons due to the poor prognoses of both the diseases. However, we believe that carefully selected patients could benefit from one stage curative resection for these synchronous tumors. We experienced a case of synchronous double cancer of the lung and esophagus and performed bilobectomy and Ivor Lewis operation simultaneously. To the best of our knowledge, this is the first report on the good result of one stage curative resection for these synchronous serious tumors in Korea.

  • The increasing incidence of multiple primary carcinomas occuring in the upper aerodigestive tract is well documented, with the accepted incidence being as high as 20-30%. The fiberoptic endoscopy has also enabled visualization of areas previously inaccessible without general anesthesia. A prospective panendoscopic examination of the upper aerodigestive tract was peformed on 104 patients with squamous cell carcinoma of head & neck in our hospital between 1989 and 1994. Five second primary cancers (4.8% :2 stomach, 2 esophagus, 1 lung cancers) were detected endoscopically. These finding should reinforce the belief that head & neck cancer is a panmucosal disease of the aerodigestive tract that silent second primary cancers are not uncommon. So every effort should be done to detect second primary cancers in head & neck squamous cell carcinomas. Panendoscopy has proved valuable in achieving that.

  • The incidence and mortality rates of liver and nasopharyngeal cancer in Guangxi province of China have always been among the highest in the world, and cancer is one of the major diseases that pose a threat to the health of residents in Guangxi. However, no systematic study has been performed to evaluate the time trends in the structure of cancer-related deaths and cancer mortality. In this study, we reveal sex, age and geography differences of cancers mortality between three death surveys (1971 to 1973, 1990 to 1992, and 2004 to 2005). The results show that the standardized mortality rate of cancer in Guangxi residents has risen from 43.3/100,000 to 84.2/100,000, the share of cancer deaths in all-cause deaths has increased from 13.3% to 20.7%, and cancer has become the second most common cause of death. The five major cancers, liver cancer, lung cancer, gastric cancer, nasopharyngeal cancer and colorectal cancer, account for 60% of all the cancer deaths. Cancers with growing mortality rates over the past 30 years include lung cancer, colorectal cancer, liver cancer and female breast cancer, of which lung cancer is associated with the sharpest rise in mortality, with a more than 600% rise in both men and women. Cancer death in Guangxi residents occurs mainly in the elderly population above 45 years of age, especially in people over the age of 65. The areas with the highest mortality rates for liver cancer and nasopharyngeal cancer, which feature regional high incidences, include Chongzuo and Wuzhou. Therefore, for major cancers such as liver cancer, lung cancer, gastric cancer, nasopharyngeal cancer and female breast cancer in Guangxi, we can select high-risk age groups as the target population for cancer prevention and control efforts in high-prevalence areas in a bid to achieve the ultimate goal of lowering cancer mortality in Guangxi.

  • Background: Cancer is a major public health problem and the leading cause of mortality in both males and females in developed and developing countries. The incidence of cancer is gender dependent. Among Iranians, it is the third cause of death. Materials and Methods: The information recorded in the files of all patients (7,695 individuals) pathologically diagnosed with cancer in Imam Reza referral hospital of Kermanshah University of Medical Sciences during the four year period of 2006-2009 were reviewed and analyzed using SPSS statistical software package version 16.0. Results: Around 61.6% of reported cancer cases were males and 38.4% were females. The most prevalent reported malignant tumors occurred at the age group of 70-79 years in males and in females these tumors were presented in the ages of 60-69 years. The most prevalent cancers among studied patients were gastrointestinal (GI) cancers with a frequency of 22.9% [gastric 10.7%, colorectal 6.9%, and esophageal 6%]. The second, third and forth prevalent cancers were blood at 16.4%, lung 13.5% and bladder 12.8%, respectively. In males the cancers of GI (25.6%) were the most prevalent followed in order of frequency by bladder (18%), blood (17.6%), lung (17.4%) and prostate (6.8%). In females the most frequent recorded cancer was breast (24.1%) followed in order of frequency by GI (20.5%), blood (14.4%), lung (7.3%), uterus (6.2%) and ovary (5.1%). Breast cancer was the most prevalent cancer (27%) in the age group of 40-49 years. Conclusions: The present study provides frequency data for various types of cancers in both males and females from a referral hospital of Kermanshah that are comparable with some reports from other areas of the country.

  • The Forkhead box M1 (FoxM1) has been shown to regulate transcription of cell cycle genes essential for $G_1$-S and $G_2$-M progression, including $p27^{kip1}$. The $p27^{kip1}$ gene is a member of the universal cyclin-dependent kinase inhibitor family. Immunohistochemical studies for FoxM1 and $p27^{kip1}$ were performed in 154 lung cancers (69 squamous cell carcinomas (SCC) and 85 adenocarcinomas (ADC)). Immunoreactivity for FoxM1 and $p27^{kip1}$ were found in 79 (51.3%) and 49 (31.8%) out of 154 cases, respectively. Forty-six (58.2%) of the 79 cases with a positive FoxM1 immunoreactivity showed a negative $p27^{kip1}$ expression in 154 lung cancers. According to histologic type, 22 (53.7%) of the 41 SCC cases with a positive FoxM1 immunoreactivity showed a negative $p27^{kip1}$ expression and 24 (63.2%) of the 38 ADC cases with a positive FoxM1 immunoreactivity showed a negative $p27^{kip1}$ expression. The expression of $p27^{kip1}$ was significantly higher in the SCC than in the ADC (P=0.050). There were no significant associations between the FoxM1 and $p27^{kip1}$ expressions and other clinicopathologic factors. These findings suggest that FoxM1 overexpression may diminish the expression of $p27^{kip1}$ protein in lung cancers. Further studies are needed to define the relation between FoxM1 and $p27^{kip1}$ for examining the mechanisms of tissue-specific FoxM1 expression.

  • Ubiquitin-conjugating enzyme E2S (UBE2S), a family of E2 protein in the ubiquitination process, is involved in development of various cancers. However, its role in lung adenocarcinoma, has not been well elucidated. In this report, we attempted to investigate expression and function of UBE2S in lung adenocarcinoma. Up-regulation of UBE2S at mRNA, and protein level, was observed in human cancer tissues and lung adenocarcinoma cells. Higher UBE2S expression correlated with poorer prognosis of lung adenocarcinoma patients. UBE2S expression was efficiently suppressed by lentivirus-mediated shRNA strategy in A549 cells, and UBE2S silencing led to reduced cell proliferation, colony formation, and enhanced apoptosis. Inverse results were observed, in UBE2S over-expressed H1299 cells. Microarray analysis indicated that a large number of genes were regulated by UBE2S, and p53 signaling pathway may be critical, to the role of UBE2S in cancer development. Together, UBE2S could be a potential target for lung adenocarcinoma.

  • Background: Cancer is the most common cause of death in Thailand, where treatment outcomes and prognosis are poor and mortality rates remain high. This study reports new cancer cases and trends of all cancers registered in Srinagarind Hospital from 1993 to 2012 and also provides a picture of the cancer situation in Northeast Thailand. Materials and Methods: All new cases of cancer registered in the hospital-based cancer registry at Faculty of Medicine, Srinagarind Hospital, Khon Kaen University during 1993-2012 were included in the study. Results and Conclusions: The number of new cancer cases has gradually increased each year during the last 20 years. The three most common cancers at present in males are liver and bile duct cancer, lung cancer and colorectal cancer, respectively. In females, liver and bile duct, breast and thyroid cancers are now the most frequent. Interestingly, the number of cases of both liver and bile duct cancer and colorectal cancer in males noticeably increased during the second decade of the study. Additionally, breast cancer greatly increased in the same decade and lung cancer in females climbed into the top five most common cancers. Thyroid cancer has also risen steadily in the last decade. Trends of common cancers are similar to those throughout Thailand.
