Methods： Clinical data of 30 patients with persistent or recurrent SCC of the cervix within one year after CCRT between July 2006 and July 2011 were analyzed retrospectively： These data were compared with those of 35 SCC cases with no signs of recurrence after complete remission. These 35 patients were treated during the same period （between 2,006 and Z011） and selected randomly. Results： Among these 30 patients, 25 exhibited distant metastases of which 14 were observed within 6 months after CCRT. Univariate analysis showed higher incidence of pelvic or para-aortic lymphadenectasis and SCC-ag 〉 10 ng/mL in the group with persistent or recurrent disease before treatment （P〈0.01）. Multivariate analysis by logistic regression revealed that the pre-therapeutic pelvic or para-aortic lymph node enlargement and SCC-ag 〉 10 ng/mL were the independent risk factors. Palliative chemotherapy was the main treatment option for patients with persistent or recurrent disease. The 2-year survival rate was 21.7%, and the median survival time was 17 months. Conclusion： Patients with persistent or recurrent SCC of the cervix after CCRT exhibited a high rate of distant metastasis with poor prognosis. The pre-therapeutic pelvic or para-aortic lymph node enlargement and SCC-ag 〉10 ng/mL were identified as the independent risk factors for persistent or recurrent SCC within i year after CCRT.展开更多

Methods： The expression of elF-4E and p53 in 32 cases of SCC was detected by immunohistochemical SABC method. Results： The positive rate of elF-4E and p53 expression was 93.8% and 56.3% in SCC, and the levels of eIF-4E and p53 were significantly higher in SCC than those in the normal skin tissue （P 〈 0.05）. Conclusion： Both elF-4E and p53 were useful markers in SCC, but the specialty and sensitivity of the eiF- 4E protein was high in SCC.展开更多

Chromosomal aberrations are detected in ~50% of cases of de novo MDS cases and the most common chromosomal abnormalities of this entity include complete or partial monosomy of chromosomes 5 and 7, partial deletion of 20q and 12p, trisomy 8, and 11q23 aberrations. A few primary and/or secondary MDS cases combined with other cancer have been reported. Case Presentation: We report here an adult MDS associated with squamous cell carcinoma (SCC). G-banding and array-proven multicolor banding (aMCB) revealed an unbalanced translocation der(7)t(1;7)(q21;q21), which led to 1q partial trisomy and 7q partial monosomy. Immunophenotype of this case was consistent with refractory anemia with excess of blasts (RAEB-2) according to World Health Organization (WHO) classification. Conclusions: As far as we know, this is the first adult MDS case associated with SCC and an unbalanced translocation t(1;7). Our patient received first cycle of azacitidine treatment and he showed bilateral pleural effusion as a secondary event. This toxicity is not limited to the first cycle as in previous MDS cases;our case is the first one to shown this toxicity as a secondary event of azacitidine treatment. As less than 10 cytogenetcially comparable cases without SCC were reported before in male MDS, we carefully conclude that this cytogenetic aberration may be a hint on a new gender associated MDS subgroup.展开更多

Malignant tumours express newer antigen on their cell surface membrane which elicit immunological reaction in and around tumoural tissue. In early part of immune reaction neutrophil, eosinophil migrates followed by monocyte-macrophage cell. Tumor associated tissue eosinophilia (TATE) is believed to play a significant role in the biological behavior of the carcinoma. Eosinophil infiltrate in association with the head and neck squamous cell carcinoma (SCC) have been reviewed from time-to-time. The significance of such an association has been variably thought to be either a potential diagnostic tool for stromal invasion or as a prognostic indicator. The aim of this study was to investigate and evaluate the possible role of the tumour associated tissue eosinophilia (TATE) as a predictive indicator for the grading and establishing prognosis of the upper aerodigestive tract squamous cell carcinoma (SCC).展开更多
