Background: Skin cancer is the most common type of cancer worldwide. It has an increasing trend. This study investigated the epidemiological trend and morphological changes in skin cancer in Iran. Materials and Methods: This study was done using existing data, extracted from the National Cancer Registry System and the Disease Management Center of Iranian Ministry of Health between 2003 and 2008. Data on epidemiologic trend was analyzed using Joinpoint software package. Results: The incidence of skin cancer is increasing in Iran, and more in men than women. There was a declining trend for basal cell carcinoma. Basal squamous cell carcinoma and melanoma had an increasing trend. The increase of skin cancer was related to squamous cell carcinoma. Conclusions: Our findings indicated that the increase of skin cancer was attributed to squamous cell carcinoma. It is necessary to be planning for the control and prevention of this disease as a priority for health policy makers.

Lung cancer is classified into squamous cell carcinoma, adenocarcinoma. large-cell carcinoma and small-cell carcinoma by histology. Squamous cell carcinoma which is frequently reported in Korea is not effected by anti-cancer chemotherapy but effected by surgery or radiotherapy. We experienced a 70 year-old male patient who had been discharged after having been diagnosed squamous cell carcinoma(stage III) and considered of a viable period of 3 month. However 2 years' taking boiled water of paecilomyces japonica and phellinus linteus, he showed normal chest X-ray and more healthy life. So it is suggested that paecilomyces japonica and phellinus linteus should be effect on squamous cell carcinoma of lung.

A case of squamous cell carcinoma of the thyroid gland associated with esophageal carcinoma is presented A squamous cell carcinoma of the thyroid gland is rare and is prognosis is poor. The histogenesis of squamous cell carcinoma is not clear, but at present, it is believed that most cases arise from the follicular epithelium It is very important to know whether squamous cell carcinoma of the thyroid is primary or secondary. Thus, the possibility of squamous cell carcinoma in the thyroid being the result of a metastasis or extension from a primary tumor in the trachea or esophagus must always be ruled out and intensive evaluation should be required to confirm the diagnosis of this disease. We report a squamous cell carcinoma of the thyroid associated with esophageal cancer with brief review of literature.

Squamous cell carcinoma and adenocarcinoma are the major histological types of non-small cell lung cancer. Because they differ on the basis of histopathological and clinical characteristics and their relationship with smoking, their etiologies may be different; for example, different tumor suppressor genes may be related to the genesis of each type. We used microarray data to construct three regulatory networks to identify potential genes related to lung adenocarcinoma and squamous cell carcinoma and investigated the similarity and specificity of them. In the network, some of the observed transcription factors and target genes had been previously proven to be related to lung adenocarcinoma and squamous cell carcinoma. We also found some new transcription factors and target genes related to SCC. The results demonstrated that regulatory network analysis is useful in connection analysis between lung adenocarcinoma and squamous cell carcinoma.

Background: Lung cancer is the leading cause of cancer mortality in the world. Many factors can protect against or facilitate its development. A TNF family member TRAIL, has a complex physiological role beyond that of merely activating the apoptotic pathway in cancer cells. Vitamin D is converted to its active form locally in the lung, and is also thought to play an important role in lung health. Our goal was to investigate the possible clinical significance of serum sTRAIL and 1,25-dihydroxyvitamin D(3) levels in patients with non-small cell lung cancer (NSCLC). Materials and Methods: Totals of 18 consecutive adenocarcinoma and 22 squamous cell carcinoma patients with stage-IV non-small cell lung cancer referred to our institute were included in this study. There were 12 men and 6 women, with ages ranging from 38 to 97 (mean 60.5) years with adenocarcinoma, and 20 men and 2 women, with ages ranging from 46 to 80 (mean 65) years with squamous cell carcinoma. Serum levels of sTRAIL and 1,25-dihydroxyvitamin D(3) were measured in all samples at the time of diagnosis. Results: sTRAIL levels in NSCLC patients were higher than in the control group. Although there was no correlation between patient survival and sTRAIL levels, the highest sTRAIL levels were correlated with age and cigarette smoking in the adenocarcinoma patients. sTRAIL level in healthy individuals were correlated with serum 1,25-dihydroxyvitamin D(3). Conclusions: Serum sTRAIL concentrations were increased in NSCLC patients, and correlated with age and smoking history, but not with overall survival.

Purpose: The objective of this study is to evaluate the survival rate and influencing factors. Patients and Methods: We studied 104 patients who were diagnosed for squamous cell carcinoma of tongue and received curative treatment in oral oncology clinic of National Cancer Center from June 2001 to December 2009. Results: We found the following results. 1. The overall 5-year survival rate of tongue cancer was 67.0% and there was no significant statistical difference between male and female. 2. A lower survival rate was shown in patients under 40 years (42.2%) than over 40 years (75.5%)(P < 0.05). 3. 5-year survival rates of patients with tongue cancer classified by pTNM classification were 87.4% in early stage and 43.3% (P < 0.05). 4. A higher survival rate was seen in patients without cervical lymph node metastasis (82.0% > 44.1%)(P < 0.05). 5. A higher survival rate was seen in patients of tongue cancer with higher differenciation grade (P < 0.05). 6. It is well known that drinking and smoking have great influence on the survival rate of patients of squamous cell carcinoma of tongue. But these was no statistical significance. Conclusion: The overall 5-year survival rate of tongue cancer was 67.0% and it was mostly influenced by factors like age, pTNM stage, cervical lymph node metastasis, differentiation of cancer cell etc.

Background: Cylin D1(CCDN1) is an important regulator of the cell cycle whose alterations are thought to be involved in cancer development. There have been many studies indicating CCDN1 amplification or over-expression in a variety of cancer types. In addition to gene amplification, the G870A polymorphism may be related with altered CCDN1 activity, and therefore with cancer development. This hypothesis has been tested in different cancer types but results have been contradictory. We therefore aimed to investigate any relationship between CCDN1 A870G genotypes and laryngeal squamous cell cancer development and progression. Materials and Methods: A total of 68 Turkish patients with primary laryngeal squamous cell cancer and 133 healthy controls were enrolled. Polymerase chain reaction-restriction fragment length polymorphism analysis was used to determine the CCDN1 genotypes. Results: No significant association was detected between CCDN1 genotypes and laryngeal squamous cell cancer (LxSCCa) development. Similarly CCDN1 genotypes were not related to clinical parameters of Lx SCCa. However, there was a very significant association between CCDN1 G allele and presence of perineural invasion (p=0.003; OR: 1.464; CI% 1.073-1.999). CCDN1 G allele frequency was significantly higher in the individuals with perineural invasion (85.7%) when compared to those without (58.5%). The 2 patients who died of disease were both found to possess the GG genotype. Conclusions: These results pose a controversy in suggesting a protective role of the G allele against LxSCCa development and support the association of CCDN1 gene GG genotype with mortality in patients with LxSCCa.

Background: Whether sirolimus is useful in the prevention of non-melanoma skin cancer (NMSC) remains unclear and we therefore performed this meta-analysis of randomized controlled trials to test the hypothesis that Sirolimus-based immunosuppression is associated with a decrease in NMSC. Methods: The main outcomes were NMSC, squamous-cell carcinoma and basal-cell carcinoma. The pooled risk ratio (RR) with its 95% confidence interval (95%CI) were used to assess the effects. Results: 5 randomized trials involving a total of 1499 patients receiving kidney transplantation were included. Patients undergoing Sirolimus-based immunosuppression had much lower risk of NMSC (RR = 0.49, 95%CI 0.32-0.76, P = 0.001). Subgroup analyses by tumor type showed that Sirolimus-based immunosuppression significantly decreased risk of both squamous-cell carcinoma (RR = 0.58, 95%CI 0.43-0.78, P < 0.001) and basal-cell carcinoma (RR = 0.56, 95%CI 0.37-0.85, P = 0.006). The quality of evidence was high for NMSC, and moderate for squamous-cell carcinoma and basal-cell carcinoma. No evidence of publication bias was observed. Conclusion: High quality evidence suggests that Sirolimus-based immunosuppression decreases risk of non-melanoma skin cancer, and Sirolimus has an antitumoral effect among kidney-transplant recipients.

Spontaneous Pneumothorax as a complication of lung cancer is rare, as seen from the literature, comprising only 1.13 per cent of all pneumothoraces. All histologic types of lung cancer have been reported principally squamous cell carcinoma probably because of its relatively higher incidence. Beside the fact that it occurs in the same high risk population [Smokers, chronic bronchitis and those with emphysema], pneumothorax may reveal a cancer. Recently, we observed three cases of lung cancer with spontaneous pneumothorax, the one was squamous cell carcinoma and the others were adenocarcinoma. Three cases of spontaneous pneumothoraces occurred as a complication of neoplastic disease.

Background: Cancer diagnostic biomarkers have a wide range of applications that include early detection of oral precancerous lesions and oral squamous cell carcinomas, and assessing the metastatic status of lesions. The interferon stimulated ISG15 gene encodes an ubiquitin-like protein, which conjugates to stabilize activation status of associated proteins. Hence a deregulated expression of ISG15 may promote carcinogenesis. Indeed overexpression of ISG15 has been observed in several cancers and hence it has been proposed as a strong candidate cancer diagnostic biomarker. Given the emerging relationship between malignant transformation and ISG15, we sought to examine the expression pattern of this gene in tumor biopsies of oral squamous cell carcinoma (OSCC) tissues collected from Indian patients. Materials and Methods: Total RNA isolated from thirty oral squamous cell carcinoma tissue biopsy samples were subjected to semi-quantitative RT-PCR with ISG15 specific primers to elucidate the expression level. Results: Of the thirty oral squamous cell carcinomas that were analyzed, ISG15 expression was found in twenty four samples (80%). Twelve samples expressed low level of ISG15, six of them expressed moderately, while the rest of them expressed very high level of ISG15. Conclusions: To the best of our knowledge, the results show for the first time an overexpression of ISG15 in up to 80% of oral squamous cell carcinoma tissues collected from Indian patients. Hence ISG15 may be explored for the possibility of use as a high confidence diagnostic biomarker in oral cancers.
