    Objective To compare the survival outcomes of patients with cervical squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) among patients with locally advanced cervical cancer that were treated with definitive radiotherapy. Methods The baseline characteristics and outcome data of patients with locally advanced cervical cancer who were treated with definitive radiotherapy between November 1993 and February 2014 were collected and retrospectively reviewed. A Cox proportional hazards regression model was used to investigate the prognostic significance of AC/ASC histology. Results The patients with AC/ASC of the cervix exhibited significantly shorter overall survival (OS) (p=0.004) and progression-free survival (PFS) (p=0.002) than the patients with SCC of the cervix. Multivariate analysis showed that AC/ASC histology was an independent negative prognostic factor for PFS. Among the patients who displayed AC/ASC histology, larger tumor size, older age, and incomplete response to radiotherapy were found to be independent prognostic factors. PFS was inversely associated with the number of poor prognostic factors the patients exhibited (the estimated 1-year PFS rates; 100.0%, 77.8%, 42.8%, 0.0% for 0, 1, 2, 3 factors, respectively). Conclusion Locally advanced cervical cancer patients with AC/ASC histology experience significantly worse survival outcomes than those with SCC. Further clinical studies are warranted to develop a concurrent chemoradiotherapy (CCRT) protocol that is specifically tailored to locally advanced cervical AC/ASC. PMID:28028992

    Objective: The role of human papillomavirus (HPV) in the development of cervical carcinoma has been clearly established but other factors could be involved in cervical tumorigenesis such as loss of heterozygosity (LOH) and microsatellite instability (MI). The aim of the present study was to investigate the genetic instability in cervical carcinoma tissues and provide evidence for discoveringnew tumor suppressor genes and screening diagnostic molecular marker of cervical carcinoma. Methods: Fifty primary cervical carcinoma samples from high-incidence area were analyzed by PCR for HPV16 infection, LOH and microsatellite instability. Results: HPV16 was detected in 88% of the cases. Sixty-six percent of total cases showed LOH with no more than 3 different loci per case. The highest frequency of the allelic loss was found in D18S474 (18q21, 40.5%). MI was detected in 4 cases (8%) only. Conclusion: Different percentages of LOH on specific chromosomal regions were found and MI was very infrequent in cervical carcinoma. The putative suppressor gene(s) could be located on specific chromosome regions such as 18q, and genetic instability could be involved in cervical tumorigenesis.

    Full Text Available Background. To determine the prognostic significance of pretreatment levels of circulating lymphocyte (CLC, neutrophil (CNC, and monocyte (CMC counts in patients with locally advanced cervical carcinoma (CC treated with definitive radiation. Methods. A retrospective, dual-institution review of patients with Stage IB2-IVA CC from 2005 to 2015. Progression-free (PFS and Overall Survival (OS were determined for high and low CLC, CNC, and CMC groups. Multivariate analysis was used to confirm prognostic value of baseline leukocyte counts. Results. 181 patients were included. Median follow-up time was 26 (3–89 months. CNC had no effect on PFS or OS. PFS was similar between CMC groups; however, OS was significantly improved for patients with low CMC (62.5 versus 45.3 months, p=0.016. High CLC was associated with improved PFS (48.5 versus 27.8 months, p=0.048 and OS (58.4 versus 34.9 months, p=0.048. On multivariate analysis, high CNC was associated with increased relapse risk (HR 1.12, p=0.006 and low CLC was associated with increased mortality risk (HR 0.67, p=0.027. Conclusion. This study demonstrates that leukocyte values can provide prognostic information in CC. These hypothesis-generating findings warrant further prospective investigations.

    Several mechanisms are involved in the development of resistance to therapy in locally advanced cervical squamous cell carcinoma (LACSCC). Studies have shown that CD44 and Lewis Y antigen (LeY) form a complex that is associated with chemoresistance, tumor invasion and metastasis. We assessed the role of CD44 and LeY in the outcome of LACSCC patients treated with different chemotherapy regimens. 126 LACSCC patients at FIGO stages IIB-IVA were selected from the GOCS database: 74 patients included in 3 different prospective phase II trials in the neoadjuvant setting (vinorelbine, docetaxel, ifosfamide-vinorelbine-cisplatin) and 52 patients treated with standard radiochemotherapy based on cisplatin (RCBC). Clinical data at baseline, disease-free survival (DFS) and overall survival (OS) were recorded. Univariate and multivariate Cox models were employed. Median age was 45.6 years (range: 24.9-80.5). Sixty-three and 47 tumors were CD44+ and LeY+, respectively. Tumors with expansive growth showed higher grade (p = 0.0024), mitotic index (p = 0.0505), tumor necrosis (p = 0.0191), LeY+ (p = 0.0034) and CD44+/LeY+ coexpression (p = 0.0334). CD44+ cells were present in 91.3% of patients with local recurrence (p = 0.0317). Advanced stage was associated with LeY+ tumors. Patients treated with RCBC had worse DFS and OS when their tumors expressed LeY (p = 0.0083 and p = 0.0137, respectively). Pre-treatment hemoglobin level, FIGO stage and tumor response remained the most significant prognostic factors in Cox regression. In our cohort of LACSCC patients, the coexpression of CD44 and LeY was not associated with worse outcome. However, in the subgroup of patients receiving RCBC, LeY expression was correlated with shorter DFS and OS.

    Objective: To evaluate factors for prognosis of cervical carcinoma. Methods: Expressions of mn23- HI, erbB3 and erbB4 were examined by immunohistochemical staining. The apoptosis was detected in situ by the TdT mediated duip-biotin nick end-labeling (TUNEL) technique. Mitotic cell were counted by HE dyeing. Results: FIGO stage and lymph node metastasis were the most important factors for evaluating prognosis in adenocarcinoma or squamous cell carcinoma. AI/MI was positively correlated with 5-year survival of cervical carcinoma. Positive expression of nm23-H1 combed with negative expression of erbB4 [nm23-H1(+)/erbB4(-)] predicted good prognosis for adeno-carcinoma. In multivariable Cox regression analysis, only FIGO stage and AI/MI were into equation. Conclusion: FIGO stage and AI/MI were independent evaluating parameter for adenocarcinoma or squamous cell carcinoma.

    Full Text Available A formidable threat to the health of women, cervical carcinoma can be prevented in many cases with adequate screening. The current guidelines for cervical carcinoma screening were created as joint recommendations of the American Cancer Society (ACS, the American Society for Colposcopy and Cervical Pathology (ASCCP and the American Society for Clinical Pathology (ASCP in 2012, and later accepted and promoted by the American Congress of Obstetricians and Gynecologists (ACOG. The 2012 recommendations underscore the utility of molecular testing as an adjunct to cytology screening for certain women and provide guidance to clinicians based on different risk-benefit considerations for different ages. This manuscript will review screening techniques and current recommendations for cervical cancer screening and human papilloma virus (HPV testing, as well as possible future screening strategies.

    To evaluate the utility of a standardized qualitative scoring system for treatment response assessment at 18F-FDG PET-CT in patients undergoing chemoradiotherapy for locally advanced cervical carcinoma and correlate this with subsequent patient outcome. Ninety-six consecutive patients with locally advanced cervical carcinoma treated with radical chemoradiotherapy (CRT) in a single centre between 2011 and 2014 underwent 18F-FDG PET-CT approximately 3 months post-treatment. Tumour metabolic response was assessed qualitatively using a 5-point scale ranging from background level activity only through to progressive metabolic disease. Clinical and radiological (MRI pelvis) follow-up was performed in all patients. Progression-free (PFS) and overall survival (OS) was calculated using the Kaplan-Meier method (Mantel-Cox log-rank) and correlated with qualitative score using Chi-squared test. Forty patients (41.7 %) demonstrated complete metabolic response (CMR) on post-treatment PET-CT (Score 1/2) with 38 patients (95.0 %) remaining disease free after a minimum follow-up period of 18 months. Twenty-four patients (25.0 %) had indeterminate residual uptake (ID, Score 3) at primary or nodal sites after treatment, of these eight patients (33.3 %) relapsed on follow-up, including all patients with residual nodal uptake (n = 4Eleven11 of 17 patients (64.7 %) with significant residual uptake (partial metabolic response, PMR, Score 4) subsequently relapsed. In 15 patients (15.6 %) PET-CT demonstrated progressive disease (PD, Score 5) following treatment. Kaplan-Meier analysis showed a highly statistically significant difference in PFS and OS between patients with CMR, indeterminate uptake, PMR and PD (Log-rank, P < 0.0001). Chi-squared test demonstrated a highly statistically significant association between increasing qualitative score and risk of recurrence or death (P < 0.001).

    To assess whether incorporation of measurements of surviving fraction at 2 Gy (SF(2)) and colony-forming efficiency (CFE) into a tumor control probability (tcp) model increases their prognostic significance. Measurements of SF(2) and CFE were available from a study on carcinoma of the cervix treated with radiation alone. These measurements, as well as tumor volume, dose, and treatment time, were incorporated into a Poisson tcp model (tcp(alpha,rho)). Regression analysis was performed to assess the prognostic power of tcp(alpha,rho) vs. the use of either tcp models with biologic parameters fixed to best-fit estimates (but incorporating individual dose, volume, and treatment time) or the use of SF(2) and CFE measurements alone. In a univariate regression analysis of 44 patients, tcp(alpha,rho) was a better prognostic factor for both local control and survival (p CFE alone (p = 0.015 for local control, p = 0.38 for survival). In multivariate analysis, tcp(alpha,rho) emerged as the most important prognostic factor for local control (p CFE was still a significant independent prognostic factor for local control, whereas SF(2) was not. The sensitivities of tcp(alpha,rho) and SF(2) as predictive tests for local control were 87% and 65%, respectively. Specificities were 70% and 77%, respectively. A Poisson tcp model incorporating individual SF(2), CFE, dose, tumor volume, and treatment time was found to be the best independent prognostic factor for local control and survival in cervical carcinoma patients.

    Cervical cancer is responsible for 10–15% of cancer-related deaths in women worldwide1,2. The etiological role of infection with high-risk human papilloma viruses (HPV) in cervical carcinomas is well established3. Previous studies have implicated somatic mutations in PIK3CA, PTEN, TP53, STK11 and KRAS4–7 as well as several copy number alterations in the pathogenesis of cervical carcinomas8,9. Here, we report whole exome sequencing analysis of 115 cervical carcinoma-normal paired samples, transcriptome sequencing of 79 cases and whole genome sequencing of 14 tumor-normal pairs. Novel somatic mutations in 79 primary squamous cell carcinomas include recurrent E322K substitutions in the MAPK1 gene (8%), inactivating mutations in the HLA-B gene (9%), and mutations in EP300 (16%), FBXW7 (15%), NFE2L2 (4%) TP53 (5%) and ERBB2 (6%). We also observed somatic ELF3 (13%) and CBFB (8%) mutations in 24 adenocarcinomas. Squamous cell carcinomas had higher frequencies of somatic mutations in the Tp*C dinucleotide context than adenocarcinomas. Gene expression levels at HPV integration sites were significantly higher in tumors with HPV integration compared with expression of the same genes in tumors without viral integration at the same site. These data demonstrate several recurrent genomic alterations in cervical carcinomas that suggest novel strategies to combat this disease. PMID:24390348

    To evaluate the prognostic properties of retropharyngeal lymph node (RP), posterior cervical lymph node (PCN), and supraclavicular lymph node (SPC), in stage IVA/IVB nasopharyngeal carcinoma (NPC) patients in setting of induction chemotherapy. We performed a retrospective study including 43 patients with stage IVA/IVB NPC (7th AJCC) treated with induction chemotherapy followed by concurrent chemo-radiotherapy. We analyzed prognosis with the multivariate Cox regression model and p-value from the Wald's test, using the backward elimination method (by likelihood ratio test and percent change of coefficient factors). Overall, 24 patients (55.8%) were in stage IVA and 19 (44.2%) in stage IVB. After a median follow-up time of 30 months, the 2-year overall survival (OS) was 79.1%, while the 2-year progression free survival (PFS) and distant metastasis free survival (DMFS) were 59.8% and 69.1%, respectively. In multivariate analysis for predicting DMFS, SPC involvement was not statistically significant (HR 3.39; 95% CI 0.76-15.07; p=0.1), whereas RP involvement was statistically significant (HR 5.81; 95% CI 1.08-31.16; p=0.04). Moreover, and more importantly, PCN involvement was the only nodal factor to predict all of DMFS, PFS, and OS (respectively HR 5.57, 95% CI 1.12-27.71, p=0.036; HR 16.05, 95% CI 1.93-133.65, p=0.01; and HR 28.02, 95% CI 2.74-286.22, p=0.005). PCN involvement is the only independent prognostic factor of stage IVA/IVB NPC patients treated by induction chemotherapy that predicts DMFS and turns this effect to PFS and OS. PCN involvement is a highly accurate predictor for failure of conventional chemo-radiotherapy. Therefore, patients with PCN involvement should be defined at high-risk, as to be investigated for a new staging system.

    Gambogic acid (GA) is an anticancer agent in phase IIb clinical trial in China. In HeLa cells, GA inhibited cell proliferation, induced cell cycle arrest at G2/M phase and apoptosis, as showed by results of MTT assay and flow cytometric analysis. Possible target-related proteins of GA were searched using comparative proteomic analysis (2-DE) and nine proteins at early (3 h) stage together with nine proteins at late (24 h) stage were found. Vimentin was the only target-related protein found at both early and late stage. Results of both 2-DE analysis and Western blotting assay suggested cleavage of vimentin induced by GA. MS/MS analysis of cleaved vimentin peptides indicated possible cleavage sites of vimentin at or near ser51 and glu425. Results of targeted proteomic analysis showed that GA induced change in phosphorylation state of the vimentin head domain (aa51-64). Caspase inhibitors could not abrogate GA-induced cleavage of vimentin. Over-expression of vimentin ameliorated cytotoxicity of GA in HeLa cells. The GA-activated signal transduction, from p38 MAPK, heat shock protein 27 (HSP27), vimentin, dysfunction of cytoskeleton, to cell death, was predicted and then confirmed. Results of animal study showed that GA treatment inhibited tumor growth in HeLa tumor-bearing mice and cleavage of vimentin could be observed in tumor xenografts of GA-treated animals. Results of immunohistochemical staining also showed down-regulated vimentin level in tumor xenografts of GA-treated animals. Furthermore, compared with cytotoxicity of GA in HeLa cells, cytotoxicity of GA in MCF-7 cells with low level of vimentin was weaker whereas cytotoxicity of GA in MG-63 cells with high level of vimentin was stronger. These results indicated the important role of vimentin in the cytotoxicity of GA. The effects of GA on vimentin and other epithelial-to-mesenchymal transition (EMT) markers provided suggestion for better usage of GA in clinic.

    Full Text Available A total of 302 patients with stage Ib and IIa cervical carcinoma were submitted to radical hysterectomy and lymphadenectomy during the period from 1980 to 1994. The morbidity rate was 37.5% and the mortality rate 0.6%. The most common intraoperative complications were injuries to the great pelvic vessels and the most frequent postoperative complications involved the urinary tract. The leading causes of morbidity were urinary infection (20.8%, bladder dysfunction (9.2% and ureteral fistulas (2.9%. Although the rate of complications was high, morbidity has been decreasing over the last five years. Thus, radical hysterectomy continues to be one of the methods for the treatment of early cervical carcinoma that presents an acceptable 5-year survival rate.

    Full Text Available Abstract Background Calcineurin (CaN is an important serine-threonine phosphatase (PP2B, which plays a crucial role in calcium-calmodulin mediated signal transduction events. Calcineurin has been implicated in pathogenesis of various diseases cardiac hypertrophy, diabetic neuropathy and Alzheimer's, however its role in neoplasia remains unclear. Results In view of this we evaluated the calcineurin activity in serum and biopsy samples collected from women diagnosed with invasive squamous cell carcinoma of cervix. A significant reduction was observed in the calcineurin activity in cancer cervix patients compared to the control group. However the calcineurin activity remained unaltered in the cervical scrapes obtained from patients diagnosed with low-grade squamous intra epithelial lesions (LSIL. Interestingly the downregulation of calcineurin activity in squamous cell carcinomas was not accompanied by any significant change in DNA-binding affinity of the transcriptional factor NFAT (Nuclear Factor of Activated T-cells. All the squamous cell carcinoma samples used in the present study were positive for high-risk human papillomavirus (HPV types. Conclusion The present study demonstrates the downregulation of calcineurin activity in squamous cell carcinoma of cervix with high risk HPV infection. We conclude that perturbations in calcineurin-mediated pathway may be involved in development of cervical neoplasia.

    The aim of this study was to explore the relationship between neutrophil-related factors, including neutrophil-lymphocyte ratio (NLR) and the responses of neutrophil to granulocyte colony-stimulating factors (RNG), and the prognosis of patients with locally advanced cervical squamous cell carcinoma (LACSCC) undergoing cisplatin-based concurrent chemoradiotherapy (CCCRT). A total of sixty LACSCC patients were enrolled in this study. We analyzed the association of NLR or RNG with clinicopathologic characteristics of these patients. The prognostic factors were evaluated by univariate and multivariate survival analysis. The optimal cut-off value of the NLR was determined to be 2.0 for the overall survival (OS). A higher level of the NLR was associated with younger age (P = 0.017) and higher baseline platelet count (P = 0.040). NLR was identified to be the only independent prognostic factor for OS by multivariate analysis (P = 0.037). The median RNG was 3.01, with a range of 1.19-16.84. RNG level was significantly associated with lymph node metastasis of these patients (P = 0.023). And higher RNG was identified as being a closely independent poor prognostic factor for OS (P = 0.055). This study showed that NLR and RNG may be used as potential biomarkers for survival prediction in patients with LACSCC receiving CCCRT.

    This study examined the biological and clinical significance of NAC1 (nucleus accumbens associated 1) expression in both cervical squamous cell carcinomas and adenocarcinomas/adenosquamous carcinomas. Using immunohistochemistry, the frequency of positive NAC1 expression in adenocarcinomas/adenosquamous carcinomas (31.0%; 18/58) was significantly higher than that in squamous cell carcinomas (16.2%; 12/74) (P = .043). NAC1 gene amplification was identified by fluorescence in situ hybridization in 5 (7.2%) of 69 squamous cell carcinomas. NAC1 amplification was not identified in the adenocarcinomas (0%; 0/58). Positive NAC1 expression was significantly correlated with shorter overall survival in squamous cell carcinomas (P NAC1 expression in squamous cell carcinomas was an independent prognostic factor for overall survival after standard radiotherapy (P = .0003). In contrast to squamous cell carcinomas, positive NAC1 expression did not correlate with shorter overall survival in adenocarcinomas/adenosquamous carcinomas (P = .317). Profound growth inhibition, increased apoptosis, decreased cell proliferation, and decreased cell migration and invasion were observed in silencing RNA-treated cancer cells with NAC1 overexpression compared with cancer cells without NAC1 expression. NAC1 overexpression stimulated proliferation, migration, and invasion in the cervical cancer cell lines TCS and Hela P3, which normally lack NAC1 expression. These findings indicate that NAC1 overexpression is critical to the growth and survival of cervical carcinomas irrespective of histologic type. Furthermore, they suggest that NAC1 silencing RNA-induced phenotypes depend on the expression status of the targeted cell line. Therefore, cervical carcinoma patients with NAC1 expression may benefit from a targeted therapy irrespective of histologic type.

    Objective To study the relationship between cell proliferation and apoptosis in cervical carcinoma and its clinical significance.Methods The cell proliferation and apoptosis of cervical epithelial cells in archival formalin-fixed,paraffin-embedded tissue sections of normal cervix ,cervical intraepithelial neoplasms(CN) and cervical squamous carcinoma were tested by using immunohistochemistry assay and DNA nick end-labeling technigue.The proliferation index(PI) and apoptosis index(AI) were calculated and their correlation with clinical and pathological data was analyzed. Results PI was gradually increased,but the AI and AI/PI ratio decreased from normal cervical epithelium,CIN to cervical carcinoma. There was no significant relationship among cell proliferation,apoptosis,clinical stages and pathological grades.High AI was always asso-ciated with a poor prognosis of the patients. Conclusion Cell proliferation and apoptosis allow to distinguish among normal epithelium,CIN and cervical carcinoma and are useful for the assessment of the malignant potential of tumor tissues.

    Purpose: To evaluate the efficacy and toxicity in patients with recurrence of cervical cancer treated with radiotherapy and simultaneous chemotherapy. Patients and methods: Between 1987 and 2001, 24 patients with recurrent cervical carcinoma were treated with concurrent chemoradiotherapy. Nine patients had incomplete tumor resection prior to radiation therapy. Irradiation was delivered to a total dose of 60 Gy, in three patients with central recurrence supplemented by brachytherapy. One patient was treated with brachytherapy alone. Simultaneous chemotherapy was done as a combined therapy of 5-fluorouracil-(5-FU, 600 mg/m{sup 2}/d1-5, 29-33) and cisplatin (20 mg/m{sup 2}/d1-5, 29-33; 16/24 patients) or of 5-FU (1,000 mg/m{sup 2}/d1-5, 29-33) and mitomycin C (10 mg/m{sup 2}/d2, 30; 1/24 patients). Cisplatin alone (25 mg/m{sup 2}/d1-5) and carboplatin alone (800 mg/m{sup 2}/d1-5) were administered in 5/24 patients (21%) and 2/24 patients (8%). Results: The 5-year local recurrence-free survival rate was 37%, disease-free survival 33%, and overall survival 34%. Grade 3 toxicity (NCI-CTC grade 3) occurred mainly as diarrhea (38%), leukopenia (33%), and nausea (21%). Severe toxicity (grade 4) was not seen in any of the patients. Conclusion: Radiation therapy with simultaneous chemotherapy for recurrences of cervical cancer is an effective treatment with acceptable toxicity. (orig.)

    In 1952 Papanicolaou et al. first diagnosed and graded cervical carcinomas based on individual "abnormal DNA contents" and cellular phenotypes. Surprisingly current papilloma virus and mutation theories of carcinomas do not mention these individualities. The viral theory holds that randomly integrated, defective genomes of papilloma viruses, which are often untranscribed, cause cervical carcinomas with unknown cofactors 20-50 years after infection. Virus-free carcinomas are attributed to mutations of a few tumor-suppressor genes, especially the p53 gene. But the paradox of how a few mutations or latent defective viral DNAs would generate carcinomas with endless individual DNA contents, degrees of malignancies and cellular phenotypes is unsolved. Since speciation predicts individuality, we test here the theory that cancers are autonomous species with individual clonal karyotypes and phenotypes. This theory postulates that carcinogens induce aneuploidy. By unbalancing mitosis genes aneuploidy catalyzes chain reactions of karyotypic evolutions. Most such evolutions end with non-viable karyotypes but a few become new cancer karyotypes. Despite congenitally unbalanced mitosis genes cancer karyotypes are stabilized by clonal selections for cancer-specific autonomy. To test the prediction of the speciation theory that individual carcinomas have individual clonal karyotypes and phenotypes, we have analyzed here the phenotypes and karyotypes of nine cervical carcinomas. Seven of these contained papilloma virus sequences and two did not. We determined phenotypic individuality and clonality based on the morphology and sociology of carcinoma cells in vitro. Karyotypic individuality and clonality were determined by comparing all chromosomes of 20 karyotypes of carcinomas in three-dimensional arrays. Such arrays list chromosome numbers on the x-axis, chromosome copy numbers on the y-axis and the number of karyotypes arrayed on the z-axis. We found (1) individual clonal

    The present study aimed to evaluate the efficacy and toxicities of nadaplatin-based concurrent chemoradiotherapy (CCRT) in patients with stage IIA to IVA cervical carcinoma. Patients with an International Federation of Gynecology and Obstetrics (FIGO) stage IIA to IVA cervical carcinoma were treated with nadaplatin-based CCRT, using high-dose rate intracavitary brachytherapy (HDR-ICBT) or radiotherapy (RT) alone, in patients with FIGO stage IIA to IVA cervical carcinoma. CCRT with nedaplatin (80 mg/m(2)) was administered on Days 1 and 29. The records of 17 women treated either with nadaplatin-based CCRT using HSR-ICBT (n=8) or RT alone (n=9), for stage IIA to IVA cervical carcinoma were retrospectively reviewed. The activity and toxicity were compared in the two treatment groups. Progression-free survival (PFS) and overall survival (OS) were the main endpoints. The 5-year overall survival rates in the CCRT and RT groups were 68.6 and 77.8%, respectively. The median OS of the CCRT and RT groups was 38.5 and 27.3 months, respectively. There was no significant difference in either PFS (P=0.618) or OS (P= 0.231). The most common grade 3-4 or higher toxicities in the CCRT groups were leuko-/neutropenia (37.5%). The frequency of acute grade 3-4 toxicity was higher in the CCRT compared to the RT group. However, no statistically significant difference was observed. Nedaplatin-based CCRT was safely performed. Although the prognosis of patients with FIGO stage IIA to IVA cervical carcinoma was not significantly improved, fewer distant relapses were observed in this treatment. Consequently, nedaplatin-based CCRT may be considered as a potential alternative to cisplatin-based CCRT in this patient population.

    Senescence and apoptosis are two key mechanisms that protect against cancer development. Many cell cycle regulators, such as p14(ARF), p15(INK4b) and p16(INK4a), are important in G1 cell cycle arrest and oncogene-induced senescence. The bcl-2 protein is one of the key components that control apoptosis, while the p53 protein plays key roles in both mechanisms. The genes of these key regulator proteins are often mutated or deleted in various malignancies. It is unknown how senescence and apoptosis are regulated in one of the most common tumors of the female genital tract, cervical squamous cell carcinoma (SCC). In this study the, expression of senescence, apoptosis and proliferation markers in normal cervical epithelium, cervical intraepithelial neoplasia (CIN) and SCC are characterized via immunohistochemical staining for p14(ARF), p15(INK4b), p16(INK4a), bcl-2, p53 and Ki-67 in tissue microarray blocks containing 20 samples each of normal cervix, moderate-to-severe cervical dysplasia (CIN II-III) and invasive SCC. Samples are derived from 60 total cases of cervical biopsies and cervical conizations. Results showed that the proliferation marker, Ki-67, is markedly increased, and the senescence markers, p15(INK4b), p16(INK4a) and p14(ARF) are overexpressed in both dysplasia and carcinoma. P53 immunostain is negative in all normal cervical tissue, and positive in dysplasia and carcinoma. Although the expression of bcl-2 is increased in dysplasia, this marker is negative in approximately half of SCC cases. These results suggest that some senescence pathways are activated and are still maintained in cervical dysplasia and carcinoma. However proliferation is increased and carcinogenesis is not thwarted, leading to eventual development of cervical cancer. Other mechanisms, such as those that account for the apparent overexpression of p53 and paradoxical loss of bcl-2 expression in some SCC cases, as well as additional senescence and apoptotic pathways, may play key roles

    Objective:To study the expressions of IMP3 and MVD in normal cervical tissue, CIN, and squamous cell carcinoma of cervix and investigate their relationship with the occurrence and development of cervical carcinoma.Methods:Immunohistochemistry S-P method was used to detect the expressions of IMP3 and MVD in 50 cervical invasive carcinoma tissues, 35 CIN tissues and 15 cervicitis tissues respectively.Results: There were significant differences in pair wise comparison of the expressions of IMP3 and MVD in cervical carcinoma, CIN and normal cervical tissues (P<0.05). IMP3 and MVD value were highly expressed in cervical carcinoma tissues, and were correlated with clinical staging, lymphatic metastasis and differentiation degree of cervical carcinoma (P<0.05); IMP3 and MVD value were correlated with their expressions in cervical carcinoma tissues (r=0.323P=0.022).Conclusion: IMP3 and MVD are associated with the occurrence as well as the invasion and metastasis of cervical carcinoma, and can be used as a proper indicator of the malignancy degree and prognosis of cervical carcinoma.

    Objective: To evaluate the overall complications, major as well as minor, in patients treated for early-stage cervical carcinoma as related to treatment parameters. Methods: In this retrospective study, 167 consecutive patients with early-stage cervical carcinoma treated with preoperative radiotherapy and radical hysterectomy were investigated. Clinical data were collected from the medical files. Results: Transient or permanent complications appeared in up to half of all patients. Seven percent exhibited intraoperative complications and 35% suffered from early postoperative urinary tract problems; most frequently urinary tract infection. After one year, the urinary tract complications dominated; voidance difficulties and incontinence being most common. Gastrointestinal complications occurred in 15% of patients. Lymphedema appeared during the first year in 21% of the patients but several of the mild or moderate cases improved after the first year. The relative risk of lymphedema was increased with shorter duration of surgery, extensive preoperative irradiation to the bladder and after external postoperative irradiation. Some form of late sequelae remained in every fifth patient, and every fourth patient, aged 23-44 years, periodically suffered from vasomotor symptoms despite estrogen replacement therapy. Conclusion: The complications after radiotherapy and radical hysterectomy in early stage cervical carcinoma suggest that attempts should be made to evaluate effective treatments designed to minimize risk to the patients.

    To quantify and discuss the prevalence of unsuspected thyroid lymph node metastases discovered in specimens from neck dissection for head and neck squamous cell carcinoma (HNSCC) and discuss the impact on patient management. Retrospective study between May 2004 and January 2007. University hospital. Pathological analysis of cervical lymph node dissection performed during surgery for HNSCC in a total of 349 neck dissections in 266 consecutive patients. Twenty-one patients showed metastatic lymph nodes from thyroid cancer (prevalence 7.9%): 13 cases were metastatic from a papillary thyroid carcinoma and 8 cases from a follicular carcinoma. In 5 of the 21 patients, classical dissection was associated to recurrent nerve dissection and unilateral lobectomy; no thyroid carcinoma was found. Thirteen patients received radiotherapy for HNSCC. Follow-up comprised annual ultrasonographic examination of the neck and thyroid in these 21 patients. Total thyroidectomy was decided on in 5, with discovery of 3 micro-papillary thyroid carcinomas, in a single patient (complementary (131)I treatment). No thyroid carcinomas were found for the other 4 patients. No patients died from thyroid carcinoma during follow-up (mean: 41 months). The prevalence of lymph node metastasis from thyroid carcinoma in cervical lymph node dissection during treatment of HNSCC seems higher (7.9%) than rates reported in the literature (0.3 to 1.6%). This may be due to the histopathological methods employed. Management of patients should be discussed in the light of thyroid ultrasonography and prognosis of HNSCC.

    OBJECTIVE To observe the curative effects and complications of californium-252 (252Cf) neutron intraluminal brachytherapy (IBT) combined with external irradiation (El) for treatment of cervical carcinoma.METHODS From December 2000 to December 2004, 128 cases of cervical carcinoma staged into ⅡA~ⅢB according to the International Federation of Gynecology and Obstetrics (FIGO) standards were treated with 252Cf neutron IBT using 8~10 Gy per fraction, once a week. The total dose at reference A point was 36~40 Gy in 4~5 fractions. From the second day after 252Cf neutron IBT treatment, the whole pelvic cavity was treated with 60Co γ-ray El, applying 2 Gy per fraction, 4 times per week. After 20~25 Gy of El, the center of the whole pelvic field was blocked with 4 cm of lead in width. The total dose of El was 45~50 Gy.RESULTS The short-term therapeutic effects were CR 95.3% and PR 4.7%. The 3 and 5-year local control rates were 93.5% and 87.9%. The overall 3-year survival rate was 87.5% and for Stages Ⅱ and Ⅲ , 90.9%and 81.5% respectively; the overall 5-year survival rate was 70% and for Stages Ⅱ and Ⅲ, 76.2% and 61% respectively. The rate of radiation complications was 4.7% for radiation cystitis, 7.8% for radiation proctitis, 6.3%for vagina contracture and adhesion and 5.5% for protracted radiation proctitis.CONCLUSION An combination of 252Cf neutron IBT with El for treatment of cervical carcinoma can be well-tolerated by cervical carcinoma patients. The rate of local tumor control is high and radiation complications are few.

    Full Text Available CONTEXT AND PURPOSE: Uterine cervical ectopy (cervical erosion is today considered to be a physiological condition, but there still seems to be a strong tendency towards treating it. The purpose of this study was to review the medical literature for evidence regarding benefits from treating cervical ectopy. METHODS: The following databases were reviewed: Medical Literature Analysis and Retrieval System Online (Medline, Excerpta Medica Database (Embase, Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs and Cochrane Library databases. In addition, six medical textbooks were consulted. RESULTS: The review showed that: 1 there is probably an association between ectopy and higher risk of Chlamydia trachomatis, human papillomavirus and human immunodeficiency virus infection; 4 there is probably an association between ectopy and cervical intraepithelial neoplasia; 5 there is an association between ectopy and mucous discharge and nocturia; and 6 there is no evidence of an association between ectopy and cervical cancer, or of protection against cervical cancer associated with ectopy treatment. CONCLUSIONS: 1 No data were found in the medical literature to support routine treatment for ectopy; 2 Treatment could be recommended for symptom relief, but more symptoms are attributed to ectopy than could be demonstrated in a controlled study; 3 Further studies to test the hypothesis of protection against cervical cancer associated with treatment are necessary.

    Purpose: To retrospectively analyze the outcomes and prognostic factors of cervical esophageal squamous cell carcinoma (SCC) treated with intensity modulated radiation therapy (IMRT). Methods: Thirty-seven patients with cervical esophageal SCC treated with IMRT were analyzed retrospectively. They received 54–66 Gy in 27–32 fractions. Nineteen patients received concurrent (n=12) or sequential (n=7) platinum-based two drugs chemoradiotherapy. Overall survival (OS), local control rates (LCR) and prognostic factors were evaluated. Acute toxicities and patterns of first failures were observed. Results: The median follow-up was 46 months for alive patients. The l-, 3-, 4- and 5-year OS of the all patients were 83.8%, 59.1%, 47.5% and 32.6% respectively. The median survival time was 46 months. The l-, 3-,4- and 5-year LCR were 82.9%, 63.0%, 54.5% and 54.5%, respectively. Univariate and Multivariate analysis all showed that size of GTV was an independent prognostic factor (p=0.033, p=0.039). There were no patients with Grade 3 acute radiation esophagitis and Grade 2–4 acute pneumonitis. The local failure accounted for 70.0% of all treatment-related failures. Conclusion: IMRT is safe and effective in the treatment of cervical esophageal squamous cell carcinoma. Size of GTV is an independent prognostic factor. Local failure still remains the main reason of treatment failures. The authors declare no conflicts of interest in preparing this article.

    Although cervical cancer is preventable with early detection, it remains the second most common malignancy among women. An understanding of how proteins change in their expression during a particular diseased state such as cervical cancer will contribute to an understanding of how the disease develops and progresses. Potentially, it may also lead to the ability to predict the occurrence of the disease. With this in mind, we aimed to identify differentially expressed proteins in the plasma of cervical cancer patients. Plasma from control, cervical intraepithelial neoplasia (CIN) grade 3 and squamous cell carcinoma (SCC) stage IV subjects was resolved by two-dimensional gel electrophoresis and the resulting proteome profiles compared. Differentially expressed protein spots were then identified by mass spectrometry. Eighteen proteins were found to be differentially expressed in the plasma of CIN 3 and SCC stage IV samples when compared with that of controls. Competitive ELISA further validated the expression of cytokeratin 19 and tetranectin. Functional analyses of these differentially expressed proteins will provide further insight into their potential role(s) in cervical cancer-specific monitoring and therapeutics.

    Serum and cervical tissue copper (Cu), zinc (Zn) and magnesium (Mg) levels were determined by atomic absorption spectrophotometry in 65 women with cervical carcinoma and compared with levels in 30 healthy women. The patients mean serum Cu level (184.8 +/- 12.3 mugr/dl) was significantly higher than the control group (p cancerous tissues of patients with cervical carcinoma were not statistically significant (p > 0.05). There was also no significant difference between FIGO Stage I and IIA patients according to their serum and tissue concentrations of these trace elements. We concluded that serum and tissue copper, zinc and magnesium determinations have no use in cervical carcinoma management.

    2001-01-01

    Objective To study the expression of a novel inhibitor of apptosis and survivin in cervical carcinoma and its relationship to the expression of Bcl-2.Methods Using SP immunohistochemical technique, we examined the expression of survivin and Bcl-2 in 59 cervical invasive squamous cell carcinomas.Results Survivin was expressed in 41 of 59 cases(69.5%) of cervical carcinomas. In contrast, no expression of survivin in normal cervical tissues was observed. Overexpression of survivin was related to the tumor grade and clinical stage. Survivin positive cases were strongly associated with Bcl-2 expression(80% versus 35.7%;P<0.005).Conclusion Apoptosis inhibition by survivin abnormal expression, alone or in cooperation with Bcl-2, may participate in the onset and progression of cervical carcinoma. Survivin is a new diagnostic/therapeutic target in cervical cancer.

    A range of cancer types, at increased rates, is described in renal transplant recipients receiving immunosuppression. Aside from immunodeficiency, heightened medical surveillance for cancer, lifestyle, and other risk factors all play a role. Although the relation between cancer risk and degree of immunodeficiency might not be linear, and might be different for a wide range of cancer subtypes, human papillomavirus-related cancers in long-term transplant recipients may suggest the role of even modest immunosuppression, when present long enough. High-risk human papillomavirus types are recognized as the cause of cancer of the cervix. We report a 49-year-old female renal transplant recipient diagnosed with cervical squamous cell carcinoma, 5 years after the transplant. Based on this patient, we highlight difficulties in surgical approach and the importance of close clinical follow-up including regular gynecologic screening for cervical premalignant and malignant lesions.

    We reviewed our experience with 262 consecutive two-layer, hand-sewn cervical esophageal anastomoses in patients undergoing surgery for esophageal carcinoma. Anastomotic leak rates were determined for the entire group and the frequency of post-operative esophageal dilatations was obtained for the first 101 patients. It was assumed that the frequency of dilatations would reflect the frequency of anastomotic strictures. The overall leak rate was 0.8% (two patients). Overall hospital mortality was 2.7%. No patient died as a result of anastomotic leakage. In our series, 26% of patients required at least one dilatation. If a dilatation was needed, the majority occurred within the first 6 months. We conclude that using a standardized, two-layer hand-sewn anastomotic technique cervical esophageal anastomoses may be performed safely with results similar to those reported using intrathoracic techniques.

    2012-01-01

    Cervical spondylosis is a common and disabling condition. It is generally felt that the initial management should be nonoperative, and these modalities include physiotherapy, analgesia and selective nerve root injections. Surgery should be reserved for moderate to severe myelopathy patients who have failed a period of conservative treatment and patients whose symptoms are not adequately controlled by nonoperative means. A review of the literature supporting various modalities of conservative management is presented, and it is concluded that although effective, nonoperative treatment is labour intensive, requiring regular review and careful selection of medications and physical therapy on a case by case basis.

    OBJECTIVE To evaluate the efficiency of surgery plus radiotherapy and chemotherapy versus radiotherapy plus chemotherapy in the treatment of older patients with stage I or II cervical carcinoma and to seek suitable treatment for such patients. METHODS The clinical data of 179 elderly women with stage la or lib cervical cancer were analyzed retrospectively. One hundred and thirty-four cases underwent radical hysterectomy followed by adjuvant radiotherapy and/or chemotherapy (Group 1). Forty-five cases underwent radiation therapy plus adjuvant chemotherapy (Group 2). RESULTS The 5-year survival rates in group 1 and group 2 were 78.3% and 49.1%(P=0.04), respectively. The incidence of complications in group1 was 47.0%. Three patients died of complications after radical hysterectomy. The incidence of complications in group 2 was 75.6%. CONCLUSION Elderly patients with stage I or II cervical carcinoma should receive an operation if possible. In addition they should receive adjuvant treatments according to their personal conditions, and be treated with appropriate adjuvant chemo-and/or radiotherapy.

    Objective: To explore the influence of clinical and pathologic parameters on the prognosis of squamous cell carcinoma and adenocarcinoma. Methods: 702 cases of cervical carcinoma were retrospec-tively studied. Cox regression model was informed in multi-variable analysis. Results: The retrospective analysis showed that 630 out of 702 cases of cervical carcinoma were squamous cell carcinoma, cumulative rate 89.4% and 72 case were adenocarcinoma, cumulative rate 10.6% respectively. The 5-year survival rate was lower for patients with adenocarcinoma than for patients with squamous cell carcinoma (58.3% vs 57.3%), but there was no significant difference. Cox regression model showed that the variable into equation for squamous cell carcinoma included tumor grade of differentiation, lymph node metastasis and FIGO stage, but only lymph node metastasis and FIGO stage for adenocarcinoma. Conclusion: FIGO stage and lymph node metastasis was independent parameter evaluating prognosis of cervical carcinoma.

    Objective: To explore the relationship between microsatellite alterations of RASSF1A gene and the development of cervical carcinoma, and its relationship with HPV16 infection. Methods: Two sites of microsatellite polymorphism of RASSF1A gene were selected. Polymerase chain reaction (PCR) technique was used to detect LOH and MSI in 50 cases of cervical carcinoma and 40 cases of cervical intraepithelial neoplasia (CIN), and to detect the infection state of HPV16. Results: At D3S1478 and D3S4604, the LOH rates of cervical carcinomas were 32.6% (14/43) and 48.9% (23/47), the MSI rates were 14% (6/43) and 19.1% (9/47), respectively. The LOH rates of CINs were 31.4% (11/35) and 39.5% (15/38), the MSI rates were 11.4% (4/35) and 15.8% (6/38), respectively. There were no significant differences between cervical carcinomas and CINs in respect to their positive rates of LOH and MSI at D3S1478 and D3S4604 (P>0.05). There were significant differences in LOH rates at D3S1478 and D3S4604 between the stage Ⅰ-Ⅱ and Ⅲ-Ⅳ cervical carcinomas and between the well/moderately differentiated cervical carcinomas and the poorly differentiated cervical carcinomas (P<0.05). The positive rates of LOH and MSI for CIN Ⅲ and noninvasive cervical carcinomas were higher than those in CIN Ⅰ-Ⅱ. The rates of the infection of HPV16 in cervical cancer was obviously higher than that in CIN and in normal cervical tissues (P<0.05), and the incidence of LOH of RASSF1A gene was higher in HPV16(+) than that in HPV16(-) (P<0.05). Conclusion: The RASSF1A gene change is a relatively late event in cervical carcinomas. The detection of LOH and MSI of RASSF1A gene might be helpful to the early diagnosis and the screening of cervical carcinoma. It might also be useful for predicting the prognosis of cervical carcinoma.

    Full Text Available Objective To inquire into the expression and its clinical significance of sulfiredoxin (Srx in cervical squamous cell carcinoma tissue. Methods SABC immunohistochemical method was used to detect the expression levels of Srx in specimens of 104 cervical squamous cell carcinoma and the corresponding adjacent tissues, 15 cervical intraepithelial neoplasm (CIN Ⅲ, and 20 normal cervical squamous cell epithelium tissue. The relationship between the expression of Srx protein and clinical pathological parameters of the cancer was also analyzed. Results The positive expression rates of Srx in CIN Ⅲ and cervical squamous cell carcinoma [73.3%(11/15 and 82.7%(86/104, respectively] were significantly higher than that in normal cervical tissue [35.0%(7/20, χ2=17.778, P=0.000]. Meanwhile, Srx expression in cervical cancer specimens was significantly higher than that in normal adjacent tissues (χ2=56.224, P=0.000. The positive expression of Srx in cervical squamous cell carcinoma was significantly correlated with lymph node metastasis, the depth of cancer invasion, and the infiltration of blood vessels (P0.05. Conclusion The higher expression of Srx protein might be a valuable marker for the early diagnosis and evaluation of prognosis in patients with cervical squamous cell carcinoma.

    Full Text Available Cervical carcinoma with squamous cells has many of the characteristics of avenereal disease: high incidence (over 500.000 cases every year, an increased frequency for the women with multiple sex partners and the presence of one of the papillomavirus genotypes with a high carcinogenic risk (HPV 16, 18, 31 and 45 in 100% of the cases. Material and methods.In the period of time 2001-2012, in the Department of Obstetrics and Gynecology belonging to “Sf. Apostol Andrei” Emergency Hospital in Galaţi, 5047 women were hospitalized under the suspicion of having cervical neoplasia.As part of the screening programme, the women belonging to the high risk group are tested for HPV by using Hybrid Capture 2 (HC2.Results and discussions.The seropositive women’s risk of having a persistent HPV infection is 7 times higher than in the case of the seronegative ones, with the same age. This risk is double for the women with CD4 lymphocytes below 200/mmc.Infection with cancer-causing HPV types is limited to the epithelium of the uterine exocervix and it does not spread to other parts of the body. Conclusions. Cervical cancer is caused by the oncogenic types of HPV, types 16 and 18 being responsible for over 70% of the cases. It represents the second cause of mortality by cancer for the women between 15 and 44 years old. Anti-HPV vaccination comes as a partner of the screening programmes aiming to reduce the incidence and mortality by cervical cancer.

    Forty-nine patients aged {le} 45 years, with cervical carcinoma stage IB ({le} 3 cm) were treated with either primary radical surgery (n = 26), or intracavitary irradiation followed by radical surgery (n = 23). With primary surgery, ovarian function had been preserved in 15 of the 25 patients, who were alive and well. Seven of the primary surgery patients were irradiated postoperatively and 2 others with a central recurrence were cured by irradiation. One other patient, who was not irradiated postoperatively, had an intestinal metastasis and died of the disease. If any of the adverse prognostic factors (as reported in the literature) had been considered as an indication for postoperative irradiation, 17 patients instead of 7 would have been irradiated after primary radical surgery. In the comparable group of 23 patients treated by intracavitary irradiation and radical surgery (and in 4 cases postoperative irradiation as well) there was no recurrence. There was no significant statistical difference between the treatment results in the cesium + surgery group and those who underwent primary radical surgery. Young patients with early cervical carcinoma without prognostic indicators for postoperative irradiation can benefit from primary radical surgery, because their ovarian function can be preserved.

    Telomerase activity was examined in invasive cervical carcinoma to assess whether it is activated during cervical malignant transformation and to look for its possible association with human papillomavirus (HPV) infection. Histologically confirmed invasive cervical carcinomas and benign cervices were assayed for telomerase activity by using a modified telomere repeat amplification protocol (TRAP). The same cases were subjected to polymerase chain reaction (PCR) detection of HPV by using consensus primers and type-specific (HPV types 16 and 18) primers. Telomerase activity was detected in 40 of 45 (88.9%) invasive cervical carcinomas and 2 (all chronic cervicitis) of 50 (4%) benign cervical lesions. HPV was detected in 36 (24 HPV-16 and 4 HPV-18 cases) of 45 (80%) invasive cervical carcinomas and 20 (11 HPV-16 and 1 HPV-18 cases) of 50 (40%) benign cervical changes. There was a significant correlation between the expression of telomerase with histological grade (φ=0.44, P<0.005), but no correlation was found between telomerase expression and HPV-18 (P>0.05). Although larger sample studies are needed, there seems to be a clear association between telomerase upregulation and HPV status, mainly HPV-16 infection.

    A metal oxide nanoparticle has been widely investigated for its potential use in the biomedical application. The present study investigates the cytotoxicity of ZnO nanoparticle in human cervical carcinoma cells. Cell viability was determined, and it showed the possible cytotoxic effect of ZnO nanoparticles. The characteristic apoptotic features such as rounding and loss of adherence were observed in the treated cells. Fluorescence and Confocal Laser Scanning Microscope (CLSM) studies have showed reduced nuclear volume and condensed cytoplasm. The mRNA expression of apoptotic gene p53 and caspase 3 was up-regulated following ZnO nanoparticle exposure, which confirms the occurrence of apoptosis at the transcriptional level. Reactive oxygen species (ROS) was increased in a dose-dependent manner, and initiate lipid peroxidation of the liposomal membrane, which in turn regulate several signaling pathways and influencing the cytokinetic movements of cells. ZnO nanoparticles showed a dynamic cytotoxic effect in cervical carcinoma cells. ZnO nanoparticle might induce the apoptosis through increased intracellular ROS level. Moreover, up-regulated apoptotic gene expression confirms the occurrence of apoptosis. Taking all these data together, it may be concluded that ZnO nanoparticle may exert cytotoxicity on HeLa cell through the apoptotic pathway, implies the probable utility of ZnO nanoparticle in the cancer treatment and therapy.

    Full Text Available Purpose: The aim was to explore the efficacy and safety of ultrasonography-guided percutaneous radiofrequency ablation (RFA for cervical lymph node metastases from thyroid carcinoma. Materials and Methods: Eight patients with previous total thyroidectomy and radioiodine therapy were enrolled in this study. A total of 20 cervical lymph node metastases were confirmed by percutaneous biopsy. Participants underwent ultrasonography-guided RFA treatment for all confirmed metastatic lymph nodes. Contrast-enhanced ultrasound (CEUS and sonoelastography were performed to rapidly evaluate treatment responses before and shortly after RFA. Routine follow-up consisted of conventional US, CEUS, sonoelastography, thyroglobulin level, and necessary fine needle aspiration cytology. Results: All eight patients were successfully treated without obvious complications. Post-RFA CEUS showed that total metastatic lymph nodes were ablated. The sonoelastographic score of ablated area elevated significantly shortly after RFA (P < 0.001. With a mean follow-up of 9.4 ± 5.1 months, there were no evidences of recurrence at ablated sites; however, two new cervical recurrent lymph nodes occurred in one case, which was successfully ablated as well. The mass volume shrinkages of the ablated nodes were observed in all cases. We found that 5 treated lymph nodes disappeared, 4 were reduced more than 80%, 9 were reduced between 50% and 80%, and 2 were reduced less than 50%. At the last follow-up evaluation, the serum thyroglobulin levels had decreased in 6 of 8 patients. Conclusion: Ultrasonography-guided percutaneous RFA for cervical lymph node metastasis of thyroid malignancy is a feasible, effective, and safe therapy. This procedure shows a nonsurgical therapeutic option for metastatic lymph nodes in patients with difficult reoperations or inoperations, it may reduce or delay a large number of highly invasive repeated neck dissections.

    Full Text Available Abstract Background Papillary thyroid microcarcinomas are tumors often found accidentally after thyroidectomy for other thyroid disorders. Methods Patients with enlarged lateral cervical masses, with unknown thyroid disease, found to have metastases from papillary thyroid carcinoma ≤10 mm in diameter, were compared to patients operated on for nodular or multinodular goiter, who were incidentally found to have papillary thyroid microcarcinomas. Results Group A included 24 patients with an enlarged lateral cervical mass whereas group B included 30 patients presenting with nodular or multinodular goiter. Patients in both groups underwent surgery. After thyroidectomy and lymph node dissection, pathology revealed multifocal papillary carcinomas of 1–10 mm, with invasion of the thyroid capsule and surrounding soft tissue in most of the cases in group A. Two patients presented with distant metastases at diagnosis which were surgically removed. During follow up, 3 patients (12.5% presented with new cervical metastases which were surgically removed or treated with additional radioactive iodine. At last follow-up, all patients were alive. In contrast, all patients in group B had unifocal papillary thyroid carcinoma 1–10 mm in maximum diameter, with no infiltration or extension into the adjacent tissue, or cervical lymph node metastases. Conclusion Two groups of papillary thyroid microcarcinomas characterized by different clinical and biological behaviours are identified. Significant differences were found between these groups concerning the age, tumor size, number of tumor foci, lymph nodes metastases and extrathyroidal extension of the tumor. Papillary thyroid carcinomas of small (≤10 mm size may have aggressive behaviour or be metastatic, and this subgroup should be treated and followed up as are other large, differentiated thyroid cancers.

However, few studies have investigated roles of miRNA-related SNPs in the etiology of cervical carcinoma. Methods In this case–control study of 1,584 cervical cancer cases and 1,394 cancer-free female controls, we investigated associations between two miR-218-related SNPs involved in the LAMB3-miR-218 pathway and the risk of cervical carcinoma in Eastern Chinese women. Results We found that the pri-miR-218 rs11134527 variant GG genotype was significantly associated with a decreased risk of cervical carcinoma compared with AA/AG genotypes (adjusted OR=0.77, 95% CI=0.63-0.95, P=0.015. However, this association was not observed for the miR-218 binding site SNP (rs2566 on LAMB3. Using the multifactor dimensionality reduction analysis, we observed some evidence of interactions of these two SNPs with other risk factors, especially age at primiparity and menopausal status, in the risk of cervical carcinoma. Conclusions The pri-miR-218 rs11134527 SNP was significantly associated with the risk of cervical carcinoma in Eastern Chinese women. Larger, independent studies are warranted to validate our findings.

    Full Text Available Cancer stem cells (CSCs are proposed to be responsible for high recurrence rate in cervical carcinoma. Reagents that can suppress the proliferation and differentiation of CSCs would provide new opportunities to fight against tumor recurrence. Doxycycline has been reported as a potential anti-cancer compound. However, few studies investigated its inhibitory effect against cervical cancer stem cells.HeLa cells were cultured in cancer stem cell conditional media in a poly-hema-treated dish. In this non-adhesive culture system, HeLa cells were treated with cisplatin until some cells survived and formed spheroids, which were then collected and injected into the immunodeficient mice. Cisplatin was administered every three days for five times. The tumor xenografts with CSC enrichment were cultured in cancer stem cell specific medium again to form tumorsphere, which we called HeLa-CSCs. Expression of cancer stem cell markers in HeLa-CSCs was measured by flow cytometry and qPCR. HeLa-CSCs were then treated with doxycycline. Proliferation and differentiation rates were determined by the size of spheres formed in vitro and tumor formed in vivo.We developed a new strategy to selectively enrich CSCs from human cervical carcinoma cell line HeLa, and these HeLa-CSCs are CD133+/CD49f+ cell populations with significantly enhanced expression of stem cell markers. When these HeLa-CSCs were treated with doxycycline, the colony formation, proliferation, migration and invasion, and differentiation were all suppressed. Meanwhile, stem cell markers SOX-2, OCT-4, NANOG, NOTCH and BMI-1 decreased in doxycycline treated cells, so as the surface markers CD133 and CD49f. Furthermore, proliferation markers Ki67 and PCNA were also decreased by doxycycline treatment in the in vivo xenograft mouse model.Cancer stem cells are enriched from sphere-forming and chemoresistant HeLa-derived tumor xenografts in immunodeficient mice. Doxycycline inhibits proliferation, invasion, and

    The purpose of this study was to evaluate the prognostic significance of p16 immunohistochemistry (IHC) in patients with advanced cervical cancer treated with radiation therapy. This was a retrospective study of 126 patients with International Federation of Gynecology and Obstetrics Stages Ib1-IVb cervical cancer treated with radiation. Concurrent cisplatin chemotherapy was given to 108 patients. A tissue microarray (TMA) was constructed from the paraffin-embedded diagnostic biopsy specimens. Immunoperoxidase staining was performed on the TMA and a p16 monoclonal antibody was utilized. IHC p16 extent was evaluated and scored in quartiles: 0 = no staining, 1 = 1-25% of cells staining, 2 = 26 to 50%, 3 = 51 to 75%, and 4 = 76 to 100%. The p16 IHC score was 4 in 115 cases, 3 in 1, 2 in 3 and 0 in 7. There was no relationship between p16 score and tumor histology. Patients with p16-negative tumors were older (mean age at diagnosis 65 vs. 52 years for p16-positive tumors; p = 0.01). The 5-year cause-specific survivals were 33% for p16-negative cases (score = 0) compared with 63% for p16-positive cases (scores 1, 2, 3 or 4; p = 0.07). The 5-year recurrence-free survivals were 34% for those who were p16-negative vs. 57% for those who were p16-positive (p = 0.09). In addition, patients with p16-positive tumors (score > 0) were more likely to be complete metabolic responders as assessed by the 3-month posttherapy 18 [F]-fluorodeoxyglucose positron emission tomography (FDG-PET)/computed tomograph compared with patients with p16-negative tumors (p = 0.03). p16 expression is predictive of improved survival outcome after chemoradiation therapy for advanced-stage invasive cervical carcinoma. Further testing will be needed to evaluate p16-negative cervical tumors. Copyright © 2012 Elsevier Inc. All rights reserved.

Ca-Ski and HeLa cells were transduced with lentivirus carrying miR-125a-5p mimics, and the effects of lentivirus-induced miR-125a-5p upregulation on cervical carcinoma proliferation and migration were examined by 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide and transwell assays, respectively. In additional, HeLa cells were inoculated into null mice to evaluate the effect of miR-125a-5p upregulation on in vivo cervical carcinoma growth. The direct regulation of miR-125a-5p on its target gene, ABL proto-oncogene 2 (ABL2, in cervical carcinoma was evaluated by quantitative real-time reverse transcription polymerase chain reaction, Western blotting and luciferase reporter assays, respectively. ABL2 was then downregulated by small interfering RNA to examine its effect on cervical carcinoma proliferation and migration.Results: miR-125a-5p was downregulated in both cervical carcinoma cell lines and human cervical carcinomas. In Ca-Ski and HeLa cells, lentivirus-mediated miR-125a-5p upregulation inhibited cancer proliferation and migration in vitro and cervical carcinoma transplantation in vivo. ABL2 was shown to be directly targeted by miR-125a-5p. In cervical carcinoma, ABL2 gene and protein levels were both downregulated by miR-125a-5p. Small interfering RNA-mediated ABL2 downregulation also had tumor-suppressive effects on cervical carcinoma proliferation and migration

    Purpose: Constitutively activated signal transducers and activators of transcription (STAT) factors, in particular STAT1, STAT3, and STAT5, have been detected in a wide variety of human primary tumors and have been demonstrated to directly contribute to oncogenesis. However, the expression pattern of these STATs in cervical carcinoma is still unknown, as is whether or not they have prognostic significance. This study investigated the expression patterns of STAT1, STAT3, and STAT5 in cervical cancer and their associations with clinical outcomes in patients treated with radical radiation therapy. Methods and Materials: A total of 165 consecutive patients with International Federation of Gynecology and Obstetrics (FIGO) Stages IB to IVA cervical cancer underwent radical radiation therapy, including external beam and/or high-dose-rate brachytherapy between 1989 and 2002. Immunohistochemical studies of their formalin-fixed, paraffin-embedded tissues were performed. Univariate and multivariate analyses were performed to identify and to evaluate the effects of these factors affecting patient survival. Results: Constitutive activations of STAT1, STAT3, and STAT5 were observed in 11%, 22%, and 61% of the participants, respectively. While STAT5 activation was associated with significantly better metastasis-free survival (p < 0.01) and overall survival (p = 0.04), STAT1 and STAT3 activation were not. Multivariate analyses showed that STAT5 activation, bulky tumor ({>=}4 cm), advanced stage (FIGO Stages III and IV), and brachytherapy (yes vs. no) were independent prognostic factors for cause-specific overall survival. None of the STATs was associated with local relapse. STAT5 activation (odds ratio = 0.29, 95% confidence interval = 0.13-0.63) and advanced stage (odds ratio = 2.54; 95% confidence interval = 1.03-6.26) were independent predictors of distant metastasis. Conclusions: This is the first report to provide the overall expression patterns and prognostic significance of

    Aberrant DNA methylation contributes to the malignant phenotype in virtually all types of human cancer. This study explored the relationship between promoter methylation and inactivation of the DAPK1, FHIT, MGMT, and CDKN2A genes in cervical cancer. The promoter methylation of DAPK1, FHIT, MGMT, and CDKN2A was investigated by using a methylation-specific polymerase chain reaction in 53 specimens of cervical cancer (42 squamous cell carcinoma, 11 adenocarcinoma), 22 specimens of intraepithelial neoplasia tissues, and 24 control normal cervical tissue specimens. The correlation of promoter methylation with the clinicopathological features of cervical cancer was analyzed. The expressions of DAPK1, FHIT, MGMT, and CDKN2A were detected by measuring relative mRNA levels. The promoter methylation of DAPK1, FHIT, MGMT, and CDKN2A in cervical cancer vs. intraepithelial neoplasia vs. normal cervical tissue was 75.5 vs. 31.8 vs. 4.2 % (p promoter region significantly decreased the expression of only DAPK1 (p = 0.03). The methylation rate of the DAPK1 gene promoter was significantly higher in cervical cancer tissues than in cervical intraepithelial neoplasia and normal cervical tissues. Promoter methylation may therefore lead to the inactivation of the DAPK1 gene, and may be related to the progression of cervical oncogenesis.

    Cervical lymph node metastasis is common in patients with papillary thyroid carcinoma (PTC). Salmonella species are rarely reported as causative agents in focal infections of the head and neck. The cooccurrence of lymph node metastasis from PTC and a bacterial infection is rare. This report describes a 76-year-old woman with a cervical lymph node metastasis from PTC and Salmonella infection of the same lymph node. The patient presented with painful swelling in her left lateral neck region for 15 days, and neck ultrasonography and computed tomography showed a cystic mass along left levels II–IV. The cystic mass was suspected of being a metastatic lymph node; modified radical neck dissection was performed. Histopathological examination confirmed the presence of PTC in the resected node and laboratory examination of the combined abscess cavity confirmed the presence of Salmonella Typhi. Following antibiotic sensitivity testing of the cultured Salmonella Typhi, she was treated with proper antibiotics. Cystic lesions in lymph nodes with metastatic cancer may indicate the presence of cooccurring bacterial infection. Thus, culturing of specimen can be option to make accurate diagnosis and to provide proper postoperative management. PMID:28261270

    The rat parvovirus H-1PV has oncolytic and tumour-suppressive properties potentially exploitable in cancer therapy. This possibility is being explored and results are encouraging, but it is necessary to improve the oncotoxicity of the virus. Here we show that this can be achieved by co-treating cancer cells with H-1PV and histone deacetylase inhibitors (HDACIs) such as valproic acid (VPA). We demonstrate that these agents act synergistically to kill a range of human cervical carcinoma and pancreatic carcinoma cell lines by inducing oxidative stress, DNA damage and apoptosis. Strikingly, in rat and mouse xenograft models, H-1PV/VPA co-treatment strongly inhibits tumour growth promoting complete tumour remission in all co-treated animals. At the molecular level, we found acetylation of the parvovirus nonstructural protein NS1 at residues K85 and K257 to modulate NS1-mediated transcription and cytotoxicity, both of which are enhanced by VPA treatment. These results warrant clinical evaluation of H-1PV/VPA co-treatment against cervical and pancreatic ductal carcinomas. © 2013 The Authors. Published by John Wiley and Sons, Ltd on behalf of EMBO.

    Objective To investigate the cell-type-specific enhancer (CTSE) in HPV16 and its variation in cervical carcinoma. Methods CTSEs were detected by polymerase chain reaction (PCR) in 58 cervical carcinoma from Shaanxi province; in addition variation of CTSEs was analyzed through single-strand conformation polymorphisms (SSCP). Results HPV16 CTSEs were detectable in 34 of 58 (57%) specimens and mutant rate was 41%(14/34) and the main mutations of chosen randomly variant CTSE (CTSEv) happened at YY1 binding sites in addition to glucocoticoid response elements (GRE). Conclusion CTSE in some specimens of Shaanxi province was obviously different from that in HPV16 wild type and variant CTSE might affect the transcriptional regulation of LCR on viral P97, which regulates over-expression of viral oncogenes in cervical carcinoma.

    Full Text Available Abstract Background Merkel cell polyomavirus (MCPyV was identified originally in Merkel cell carcinoma (MCC, a rare form of human skin neuroendocrine carcinoma. Evidence of MCPyV existence in other forms of malignancy such as cutaneous squamous cell carcinomas (SCCs is growing. Cervical cancers became the focus of our interest in searching for potentially MCPyV-related tumors because: (i the major histological type of cervical cancer is the SCC; (ii the uterine cervix is a common site of neuroendocrine carcinomas histologically similar to MCCs; and (iii MCPyV might be transmitted during sexual interaction as demonstrated for human papillomavirus (HPV. In this study, we aimed to clarify the possible presence of MCPyV in cervical SCCs from Japanese patients. Cervical adenocarcinomas (ACs were also studied. Results Formalin-fixed paraffin-embedded tissue samples from 48 cervical SCCs and 16 cervical ACs were examined for the presence of the MCPyV genome by polymerase chain reaction (PCR and sequencing analyses. PCR analysis revealed that 9/48 cervical SCCs (19% and 4/16 cervical ACs (25% were positive for MCPyV DNA. MCPyV-specific PCR products were sequenced to compare them with reference sequences. The nucleotide sequences in the MCPyV large T (LT-sequenced region were the same among MCPyV-positive cervical SCCs and AC. Conversely, in the MCPyV viral protein 1 (VP1-sequenced region, two cervical SCCs and three cervical ACs showed several nucleotide substitutions, of which three caused amino acid substitutions. These sequencing results suggested that three MCPyV variants of the VP1 were identified in our cases. Immunohistochemistry showed that the LT antigen was expressed in tumor cells in MCPyV-positive samples. Genotyping of human HPV in the MCPyV-positive samples revealed that infected HPVs were HPV types 16, 31 and 58 for SCCs and HPV types 16 and 18 for ACs. Conclusions This study provides the first observation that MCPyV coexists in a subset

    Metalloproteinase activities of a disintegrin and metalloproteinase 17 (ADAM17), amphiregulin (AREG), extracellular matrix metalloproteinase inducer (EMMPRIN), and matrix metalloproteinases (MMPs) are involved in tumor biology. In patients with uterine cervical carcinoma, the expression and prognostic significance of ADAM17 remain to be fully elucidated. The expression of ADAM17, AREG, EMMPRIN, phospho-epidermal growth factor receptor (p-EGFR), phospho-extracellular signal-regulated kinase (p-ERK), MMP-2, and MMP-9 was assessed by immunohistochemistry and/or Western blotting from cervical carcinoma cell lines, SiHa and HeLa cells, and cervical carcinoma tissues. AREG activity was measured by ELISA assay. The correlation of ADAM17, AREG, EMMPRIN, and MMP-9 expression with patients' survival rates was assessed by Kaplan-Meier and Cox regression analyses. RNA interference (RNAi) experiment was performed using small interfering mRNA to ADAM17 and EMMPRIN. ADAM17, EMMPRIN, and MMP-9 protein content was overexpressed in cervical carcinoma tissues compared with normal cervical tissues (P cervical cancer. ADAM17 RNAi decreased EMMPRIN, p-EGFR, p-ERK, MMP-2, and MMP-9 proteins in SiHa and HeLa cells. ELISA assay revealed that AREG activity was stimulated by ADAM17 and was reversed by ADAM17 RNAi in SiHa and HeLa cells. Our data suggest that the increased expression of ADAM17 in cervical cancer is significantly associated with aggressive progression and poor prognosis. ADAM17 may be a molecular marker for predicting the progression and prognosis in cervical cancer.

    Objective Overexpression of survivin has been reported in many human tumors. However, the clinicopathological features associated with survivin overexpression in cervical carcinoma remain controversial. Thus, the current meta-analysis was performed to assess the clinicopathological significance of survivin in cervical carcinoma. Methods PubMed, EMBASE, and Web of Science databases were searched for relevant studies published through November 1, 2015. A meta-analysis was performed to evaluate the association between survivin expression and clinicopathological outcome in cervical carcinoma. Results Eleven eligible studies with a total of 865 patients were included. Survivin overexpression was closely related to lymph node metastasis (odds ratio [OR] = 0.679, 95% confidence interval [CI]: 0.509–0.905, P = 0.008) but was not significantly associated with tumor FIGO stage (I+II vs. III+IV) (OR = 0.843, 95% CI: 0.626–1.137, P = 0.264), tumor grade (G1+G2 vs. G3) (OR = 0.913, 95% CI: 0.689–1.210, P = 0.527), tumor size (>4 vs. ≤4 cm) (OR = 0.825, 95% CI: 0.434–1.570, P = 0.559), or stromal involvement (OR = 0.820, 95% CI: 0.545–1.233, P = 0.340). The correlation between survivin expression and overall survival was evaluated among a total of 238 patients from three eligible studies. The pooled HR was 1.129 (95% CI: 0.597–1.661; P = 0.000), indicating that survivin expression was significantly associated with poor survival in cervical carcinoma. Conclusions Based on the current meta-analysis, survivin is strongly associated with lymph node metastasis and poor prognosis. Additionally, survivin is a novel clinicopathological marker of cervical carcinoma and thus may be a therapeutic target for cervical carcinoma. PMID:27764228

    Human cervical carcinoma is one of the most common malignant tumors, but the mechanisms that orchestrate the multiple oncogenic insults required for initiation and progression are not clear. Notch signaling plays a critical role in maintaining the balance between cell proliferation, differentiation, and apoptosis, but perturbed Notch signaling may contribute to tumorigenesis. We now show that Notch1 is detected in all cervical cancer, including advanced diseases. We also constitutively overexpressed active Notch1 in human cervical carcinoma to explore the effects of Notch1 signaling on human cervical carcinoma cell growth and to investigate the underlying molecular mechanisms. The signaling may participate in the development of human cervical carcinoma cells, but overexpressed active Notch1 inhibits their growth through induction of cell cycle arrest. Increased Notch1 signaling induced a downmodulation of human papillomavirus transcription through suppression of activator protein (AP)-1 activity by upregulation of c-Jun and the decreased expression of c-Fos. Thus, Notch1 signaling plays a key role and exerts dual effects, functioning in context-specific manner.

    2001-01-01

    Objective To investigate the significance of overexpression of P53 and bcl-2 protein in carcinogenesis of cervix. Methods 10 cases of cervical intraepithelial neoplasis(CIN) and 57 cases of invasive cancer were investigated with immunohistochemistry technique. Results The overexpresion of P53 protein in CIN and cervical cancer was significantly higher than that of control, respectively (P<0.01). But there was no significant difference between CIN and cervical cancer(P>0. 05). The immunoreactivity of bcl-2 in CIN was much more higher than that of control (P<0.05). The positive rate and immunoreactivity of bcl-2 in cervical carcinoma were both remarkably higher than those of control (P<0. 01) ,but there was no significant difference between CIN and cervical carcinoma (P>0. 05). It was also found that there was a remarkably positive correlation between the overexpression of bcl-2 and P53 (P<0.01). Conclusion Because of the loss of wtP53 function,the expression of bcl-2 can not be down-reguated,which is associated with the pathogenesis and development of cervical carcinoma.

    Objective: To investigate the relationship between the expression of Fas and Fas ligand (FasL) and its biological behavior in human cervix carcinoma. Methods: Immunohistochemisty technique was used to detect the expression of Fas and FasL in 47 cases of cervical carcinoma, 16 cases of cervical interaepithelial neoplasia, 10 cases of chronic cervicitis and 10cases of normal cervix. TUNEL technique was used to observe the apoptic cells in 47 cases of cervical carcinoma. Retrospective study was carried out to find the relationship between the expression of Fas and FasL and cell apoptosis, clinical stage, pathological classification, lymph node metastasis, prognosis and age. Results: The expression of Fas and FasL was significantly different in different cervix (P < 0.01 ), and also related to the degree of differentiation, lymph node metastasis and prognosis (P < 0.05).But had no relation with clinical stage or age (P > 0.05); Cervix carcinoma cells apoptosis in different pathological classification appeared negative relation (Rs=-0.35, P < 0.05). Cervix carcinoma cell apoptosis was significantly higher in Fas-positive and FasLpositive than that in Fas-negative and FasL-negative (P < 0.05). By retrospective investigation, Fas-negative and FasL-positive were related to poor prognoses of the patients with cervical carcinoma (P < 0.05). Conclusion: The development of apoptosis in cervix carcinoma has a promoting regulation function in Fas and FasL expression. Gene treatment can alter apoptosis abnormality,thus induce apoptosis in cancerous cell expressing Fas and FasL. Fas or FasL may be taken as a marker in the prognostic characterization.

    Objective To evaluate the overexpression of cyclin G1 in cervical intraepithelial neoplasia (CIN) and cervical carcinoma, and the correlation between cyclin G1 and high-risk human papilloma virus (HPV) infection.Methods All of the specimens were obtained from the Department of Pathology of China-Japan Friendship Hospital from January 2000 to August 2004. We detected the expression of cyclin G1 with immunohistochemistry, HPV16/18infection with in situ hybridization, and high-risk HPV infection with Hybrid capture system Ⅱ (HC-Ⅱ) in normal group (25 cases), CIN Ⅰ (48 cases), CIN Ⅱ (56 cases), CIN Ⅲ (54 cases), and invasive cervical squamous-cell carcinoma (SCC, 31 cases).Results The positive rates of cyclin G1 expression in CIN (77. 85%) and SCC cervical tissues (87.10%) were significantly higher than normal (8.00%,P<0.01), and the intensities of cyclin G1 expression in CIN (40.60%)and SCC cervical tissues (61.51%) were significantly higher than normal (2.72%,P<0.05). The positive rates and intensities of cyclin G1 expression increased gradually with the grade of cervical lesions. High-risk HPV infection rates were higher in CIN and SCC than normal groups (P<0.05). There was a positive correlation between cyclin G1 expression and high-risk HPV infection detected with HC-Ⅱ (Kendall's tau-b =0.316, 0.269, 0.352, and 0. 474 in CIN Ⅰ, CINⅡ, CIN Ⅲ, and SCC, respectively, P<0.05).Conclusions Cyclin G1 is overexpressed in CIN and SCC. Cyclin G1 may be a biomarker for detecting CIN and SCC. Cyclin G1 may play an important role in the oncogenesis of CIN and SCC by high-risk HPV infection.

    Full Text Available BACKGROUND Persistent infection of high risk genotypes of human papilloma virus (hrHPV has been established as the etiological cause for cervical cancer, and the most prevalent genotypes that infect the cervical tissue are HPV-16 and HPV-18. However, HPV genotype profile has been shown to differ according to geographical distribution across the globe. The present study aimed to determine the HPV genotype distribution in cervical cancer patients from Bandung, Indonesia. METHODS During the period of July – November 2010 viral DNA was extracted from randomly chosen cervical cancer biopsies and subjected to genotype determination using the diagnostic linear array genotyping test (Roche. The distribution of HPV genotypes was explored and the prevalence of HPV genotypes was mapped. RESULTS Of 96 cervical cancer tissue samples, 76 (79.2% were histopathologically classified as squamous cell cervical carcinoma. Due to the high cost of HPV genotyping tests, only twenty-five samples were randomly genotyped. Almost 90% of the cervical cancer patients were multiply infected with HPV-16 in combination with HPV-18, HPV-45, or HPV-52. The HPV-16 genotype had the highest prevalence, all samples being infected with HPV-16. CONCLUSION The cervical cancer cases were predominantly infected by multiple hrHPVs with HPV-16 as the major genotype among other hrHPVs, supporting the carcinogenic role of this hrHPV. Therefore, screening for hrHPVs in the general population is urgently needed as a means of early detection of cervical cancer.

  19. Low frequency of p53 mutations in cervical carcinomas among Brazilian women

    Directory of Open Access Journals (Sweden)

    N.A. Pinheiro

    2001-06-01

    Full Text Available Human papillomavirus (HPV infections of the high-risk types are strongly linked to the development of cervical carcinoma. The HPV oncoproteins E6 and E7 are thought to play a crucial role in this process through their interactions with the p53 protein and the retinoblastoma susceptibility gene product pRb, respectively. E6 binds to p53 protein promoting its degradation. This is considered to contribute to the oncogenesis of HPV-associated anogenital cancer. On the other hand, in HPV-negative cervical carcinoma, p53 mutations are thought to have a role in the transformation process. A total of 122 HPV-positive cervical carcinoma tissue samples were evaluated for the presence of mutations in exons 5-8 of the p53 gene by single-stranded conformation polymorphism analysis and DNA sequencing. Only four missense point mutations were detected. These findings suggest that other mechanisms independent of p53 inactivation may play a role in the genesis of cervical carcinomas.

    Human papillomavirus type 16 (HPV16) is the major cause of cervical cancer and of a fraction of oropharyngeal carcinoma. Few studies compared the viral expression profiles in the two types of tumor. We analyzed HPV genotypes and viral load as well as early (E2/E4, E5, E6, E6*I, E6*II, E7) and late (L1 and L2) gene expression of HPV16 in cervical and oropharyngeal cancer biopsies. The study included 28 cervical squamous cell carcinoma (SCC) and ten oropharyngeal SCC, along with pair-matched non-tumor tissues, as well as four oropharynx dysplastic tissues and 112 cervical intraepithelial neoplasia biopsies. Viral load was found higher in cervical SCC (<1 to 694 copies/cell) and CIN (<1 to 43 copies/cell) compared to oropharyngeal SCC (<1 to 4 copies/cell). HPV16 E2/E4 and E5 as well as L1 and L2 mRNA levels were low in cervical SCC and CIN and undetectable in oropharynx cases. The HPV16 E6 and E7 mRNAs were consistently high in cervical SCC and low in oropharyngeal SCC. The analysis of HPV16 E6 mRNA expression pattern showed statistically significant higher levels of E6*I versus E6*II isoform in cervical SCC (p = 0.002) and a slightly higher expression of E6*I versus E6*II in oropharyngeal cases. In conclusion, the HPV16 E5, E6, E6*I, E6*II and E7 mRNA levels were more abundant in cervical SCC compared to oropharyngeal SCC suggesting different carcinogenic mechanisms in the two types of HPV-related cancers.

    Full Text Available Adenoid cystic carcinoma (ACC is a rare neoplasm that usually arises from minor salivary glands. It is characteristically locally infiltrative, exhibiting perineural invasion, has a tendency for local recurrence and prolonged clinical course. A 60 year old male, chronic smoker presented with swelling of the left cervical lymph node since two months. Examination revealed a solitary firm, non tender, non mobile left cervical swelling measuring 2 x 1 cm. Fine Needle Aspiration Cytology (FNAC was done from the cervical lymph node. The diagnosis of metastatic deposits of ACC was given. Detail examination of the oral cavity revealed a small swelling at the floor of the mouth. Biopsy of the swelling confirmed ACC on histopathological examination. An unusual feature of adenoid cystic carcinoma is the low incidence of metastases to regional lymph nodes. The case is presented to highlight its unusual presentation and utility of FNAC in rapid diagnosis.

    Six hundred and nine cases of invasive squamous cell carcinoma of the cervix uteri in a retrospective analysis (1953-1982) at the A.C. Camargo Hospital, Antonio Prudente Foundation, Sao Paulo, Brazil. The patients were submitted to radical surgery and radiation therapy, individually or in combination. A multivariate analysis of the different variables were performed according to the Cox`s regression method. The variables of prognosis value, in decreasing order of importance, were: the decade of patient`s admission, the modality of therapy employed, the presence of residual tumor in the surgical specimens and the clinical stage of the disease. Other variables like ethnic group, age of first menstrual flux, menopause, number of pregnancy, kind of delivery, number and kind of abortion, were found to be of no prognostic importance. The decade of admission was of independent prognostic significance. The presence of residual tumor in the surgical specimens was more important than lymph nodes spreading, but the overall survival was affected by the increase in the number of positive lymph nodes. Patient`s age was a weak prognostic factor accounting for a reduction in the survival time among cases with age upper to 45 years old. Radiation therapy sterilizes a considerable number of lymph nodes but not all of them in every patient. There are a specific group of patients where the radical surgery is necessary in order to carry a complete debulking of the disease. (author) 82 refs., 10 figs.

    The infiltration of the parametrium represents one of the most important factors that determine the prediction and treatment of cervical carcinoma. Our objetive is to evaluate the utility of magnetic resonance imaging (MRI) in the staging of cervical carcinomas, to establish the reliability of this technique and to carry out a comparative study of the sequences used to demonstrate the parametrial invasion. We have carried out a retrospective study on 44 patients diagnosed with cervix neoplasia, using clinical exploration and performing a biopsy. the MRI studies have been carried out using a 1 Tesla magnet and the sequences used have been SE T1, Se proton density (PD) and T2 and dynamic GRE after administering gadolinium intravenously in the axial and sagital projections. The stages determined by MRI have been compared to the anatomopathological stages of the surgical specimens in cases where surgery was carried out and with the clinical stage in cases where no radical surgery was carried out. A diagnosis value of MRI has been determined to demonstrate the parametrial invasion, comparing the SE T2 sequence with the dynamic GE sequence with gadolinium. We calculate the volume of the tumour in the MRI studies to evaluate the difference of the volume between patients with tumoral stages that are clinically surgical and not surgical. MRI determines the invasion of the parametrium with a sensitivity of 88.8%, a specificity of 80% a positive value of 76.1%, a negative predictive value of 90.9% and a reliability of 83.7%. For the SE T2 sequences the sensitivity was 86.6%, the specifity 80%, the posistive predictive value 81.25%, the negative predictive value 85.7% and the reliability 83.3%. For the dynamic GE sequence with intravenous gadolinium the sensitivity was 86.6%, the specifity 86.6%, the posistive predictive value 86.6%, the negative predictive value 86.6% and the reliability 86.6%.

    Background: Extracapsular spread of cervical lymph nodes deteriorates the prognosis of patients with head and neck squamous cell carcinoma. Postoperative radiochemotherapy is superior to postoperative radiotherapy alone in patients with histologically proven extracapsular spread. If extracapsular spread can be detected preoperatively, patients may favor primary radiochemotherapy instead of primary surgery plus postoperative radiochemotherapy. Methods: Computed tomography (CT) scans of nodal positive head and neck squamous cell carcinoma patients treated between 2008 and 2010 with comprehensive neck dissection as part of first line surgical treatment were retrospectively scanned for extracapsular spread by two blinded radiologists. If a positive lymph node was identified by the pathologist, CT scans were assessed for extracapsular spread retrospectively. CT criteria for Extracapsular spread were apparent fat and soft tissue infiltration or infiltration of sternocleidomastoid muscle, internal jugular vein or carotid artery. Radiologic judgment was compared with histological evidence of extracapsular spread and specificity and sensitivity of CT detection was calculated. Results: Forty-nine patients with histologically proven positive lymph nodes (pN+) were included. Extracapsular spread was histologically proven in 17 cases; the number of all affected lymph nodes was not listed. Radiologist 1 found extracapsular spread in CT scans of 15/49 patients and radiologist 2 in 16/49 patients (Cohen's kappa = 0.86; p < 0.01). Sensitivity of radiologic extracapsular spread detection was 73% (95% confidential index (CI): 44.0–89.7%) and specificity 91% (75.0–98.0%). Conclusion: Extracapsular spread depicted on computed tomography using strict criteria has high specificity.

    Among the substances isolated from Cryptocarya sp, some styrylpyrones, such as goniothalamin, demonstrate antiproliferative activity in a broad range of human cell lines. In the present study, we assessed the cytotoxicity of a styrylpyrone (cryptomoschatone D2, isolated from Cryptocarya mandiocanna, in HPV-infected (HeLa and SiHa and uninfected (C33A human cervical carcinoma cell lines and a human lung fibroblast line (MRC-5. The cytotoxicity was tested by the MTT assay. In this assay, cells were treated with cryptomoschatone D2 at 15, 30, 60 or 90 μM for 6, 24 or 48 hours, as well as for 6 hours followed by a post-treatment recovery period of 24, 48 or 72 hours. High cytotoxicity (dose- and timedependent was observed in HeLa, SiHa, C33A and MRC-5 cell lines. Although in general the styrylpyrone cytotoxicity was not significantly different among the cell lines tested, it was apparently stronger in HeLa and C33A than in MRC-5 and SiHa in the 24 or 48-hour treatments. Moreover, HeLa and SiHa were able to recover their ability to proliferate, in direct proportion to the post-treatment recovery time. On the other hand, C33A did not demonstrate a similar post-treatment recovery. We can conclude that cryptomoschatone D2 possesses high dose-dependent or time-dependent cytotoxicity.

    Menispermum dauricum DC possesses a wide range of pharmacological effects. In this study, the mechanism of apoptosis induced by active components of M. dauricum was investigated in the human cervical carcinoma HeLa cell line. HeLa cells were treated with different M. dauricum concentrations over different time periods. The proliferation-inhibitory rate and cytotoxic effect of HeLa cells were measured by using the methyl thiazolyl tetrazolium (MTT) assay, and the apoptotic rate was detected by flow cytometry. Expressions of caspase-9, caspase-8, caspase-3, Bcl-2, and Fas proteins, in the apoptotic pathway, and the expression of nuclear factor-kappa B (NF-κB) were detected by SP immunocytochemistry. The MTT assay showed that active components of M. dauricum could significantly inhibit the growth of HeLa cells in a dose- and time-dependent manner (Pdauricum, the expressions of caspase-8, caspase-9, caspase-3, Fas protein, and NF-κB all increased, and the expression of the Bcl-2 protein decreased, with significant differences relative to the control group (Pdauricum through the NF-κB signal transduction pathway and the caspase pathway, which was related to the downregulation of Bcl-2 expression and the upregulation of Fas expression.

    The purpose of this study was to investigate the prognostic factors, such as clinical, histological and socio-demographic features affecting the event-free and overall survival of the patients with stage I-III carcinoma of the cervix. Eighty-nine patients with International FIGO stage I-III cervical cancer were treated radiation therapy and follow-up of 5-7 years were analyzed for various clinical, histopathological and socio-demographic factors influencing prognosis. Survival estimations were performed using the Kaplan-Meier method, and were compared using the un-weighted log-rank test and multivariable analysis using the Cox proportional hazards model. The median age was 46 years (range, 28-65 years). The 5-year event-free survival (EFS) and overall survival (OAS), along with standard error (SE), were 65.2% (7.0%) and 81.4% (6.1%), respectively. Significant prognostic factors for EFS include, stage (P=0.019), pelvic lymph node metastasis (P=0.013), parametrial (PMT) involvement (P=0.025), number of parametria involved (P=0.000) and tumor size (P=0.034). However, number of parametrial invasion was only significant prognostic factors for overall survival (P=0.015); 5-year survival rate was significantly lower in patients with both PMT involved (58%) than with one PMT involved (>85%). Using a multivariable analysis, we found that number of PMT involved being the only independent significant factor for the development of recurrent disease. None of the socio-demographic factors analyzed were of prognostic importance on event-free and overall survival in cervical cancer patients. Several clinicopathological factors were of prognostic significance but none of the socio-demographic factors analyzed had any role in determining patient outcome. Hence, in cervical cancer, prognosis is more likely dependent on clinical than socio-demographic factors unlike several other cancers where their significant role is well documented.

    Objective: To investigate the regulatory effect of curcumin on proliferation and apoptosis in human cervical carcinoma cell line HeLa in vitro. Methods: Human cervical carcinoma cell line Hela was cultured in vitro. HeLa cells were treated with 10(50 (mol/L curcumin for 24(72 h and the growth inhibition rates of HeLa cells were measured by MTT method. Cell apoptosis was inspected by electron microscopy. In addition, the expression of bcl-2, bcl-xl and caspase-3 protein in HeLa cell were observed by SP immunohistochemistry. Results: Curcumin inhibited the proliferation of HeLa cells on a dose-depending manner. Peak of subG1 appeared on DNA histogram in FCM. A portion of the cells presented the characteristic morphological changes of apoptosis under the electron microscope. The bcl-2, bcl-xl expression was decreased while Caspase-3 expression was increased. Conclusion: Curcumin could significantly inhibit the growth of HeLa cells; inducing apoptosis through up-regulating Caspase-3 and down-regulating expression of bcl-2 and bcl-xl was probably one of its molecular mechanisms.

    Full Text Available Cervical cancer is the second most common gynecological malignancy in the world. Human papilloma virus (HPV infection is the leading ethiologic agent in the development of premalignant and malignant cervical diseases. HPV is a member of the Papovaviridae family and until now over 100 types have been recognized. There are two types of viral infection: latent and productive. Virus induced oncogenesis is the result of interaction between virus oncoproteins E6 and E7 and tumor supresor host genes p53 and Rb. Many cofactors such as immunosuppression, early sexual relationship, multiple sexual partners, other sexualy transsmited infections and smooking are contributing factors of the precancerous and invasive cervical lesions. According to the oncogenic potential HPV are divided into three groups: low, intermediate and high oncogenic risk viruses. Molecular technics which are used for the virus detection are: In situ hibridisation,, Hybrid capture test and polymerasa chain reaction. Human papilloma virus testing has an important role in the follow up and treatment of women with 'atypical squamous cells of unknown significant' changes in cervical smears and low-grade squamous intraepithelial lesions, changes in punch biopsy.

    Cancer procoagulant (CP) is a sulfhydryl proteinase thought to be synthesized mainly by neoplastic cells. Consequently, increased CP activity in blood serum was interpreted as being associated with the presence of a proliferative process in the host's body. To date, CP activity has not been systematically studied in cases of genital carcinoma. The present study is aimed at evaluation of CP activity in women with genital carcinoma. A case-controlled study backed up by histopathological examination. Peripheral blood was sampled preoperatively in a sterile manner from an antecubital vein, from 16 women with cervical carcinoma and 15 women with uterine carcinoma. Blood for the reference group of 12 healthy women was obtained in an identical manner after an overnight fast. The CP activity in serum was determined using the coagulative method according to Gordon and Benson, and was expressed as coagulation time in seconds (s). The CP activity in 10% tissue homogenates (in saline) of genital cancer was determined by the chromogenic method according to Colucci et al. The mean CP activity in serum of women with cervical carcinoma (78.28 +/- 15.25 s) and of women with uterine carcinoma (79.63 +/- 12.02 s) was significantly different (P < 0.0001) from the respective values found in healthy women (281.33 +/- 43.19 s). The CP activity in neoplastic tissue was 28.50 +/- 6.40 nmol pNa/mL for cervical carcinoma, and 28.31 +/- 3.92 nmol pNa/mL for uterine carcinoma, both values being significantly higher (P < 0.0009) than the activity found in the normal tissues. There was no established relationship between neoplastic CP activity and FIGO staging of the disease. This is the first study to demonstrate the concomitant presence of CP activity in serum and neoplastic tissue of women with genital carcinoma. These patients have decreased coagulation time and thus are likely to develop coagulation disturbances in the course of their cancer. There may be a role for CP as a tumor marker of

    Full Text Available Squamous cell carcinoma of the larynx is the most common histologic type, accounting for up to 90% of cancers with more predilections to spread locoregionally to the cervical lymph nodes. Distant metastasis, usually to lungs, bone, and liver is seen much less frequently, with an overall incidence of 6.5–7.3%. A case of 55-year-old male with the previous history of surgery and radiotherapy treated squamous cell carcinoma of the larynx, presenting with a chief complaint of pain abdomen is hereby reported for its unusual diagnosis of metastatic deposits of squamous cell carcinoma in the omentum. Though there are reference available for peritoneum as the distant metastatic site for hypopharyngeal carcinoma, reference for laryngeal carcinoma metastasizing to omentum were not found even with an extensive search of literature. Awareness of unusual sites of distant metastasis such as omentum must be kept in mind for treated laryngeal carcinoma patients presenting with non-specific symptoms like pain abdomen. And also, chances of involvement of unusual site of the distant metastasis increases with advanced tumor-node-metastasis stage and nodal status.

    Full Text Available Ectopic cervical thymomas are often confused with thyroid or parathyroid swellings due to their anatomical positioning. Predominant epithelial thymoma can be misdiagnosed as papillary thyroid carcinoma on fine needle aspiration and lymph node metastasis of epithelial tumor on frozen section. Predominantly lymphocytic thymomas have often been misinterpreted as Hashimoto′s thyroiditis or malignant lymphoma, either by fine needle aspiration or on frozen section analysis. If cytology is doubtful and is not correlating with clinical, anatomical and surgical findings; immunohistochemistry is a very important tool in such cases to give final answer. Thyroid cell specific proteins such as thyroglobulin, thyroid transcription factor-1, thyroperoxidase and dipeptidyl aminopeptidase-4, neuroendocrine markers chromogranin, calcitonin and parathyroid hormone could be used to rule out thyroid or parathyroid origin. We present such rare case of ectopic cervical thymoma mimicking as papillary thyroid carcinoma.

    Human papillomavirus type 16 (HPV-16) is a high-risk DNA tumor virus involved in the development of cervical carcinomas. Substantial studies have demonstrated that E6 and E7 oncoproteins of HPV-16 could induce cell proliferation and immortalization. Repression of E6 and/or E7 oncogenes may induce cervical cancer cells to undergo apoptosis or senescence. The purpose of this study was to determine whether activation of the p53 and retinoblastoma (Rb) pathway by HPV-16 E6 and E7 repression was responsible for apoptosis and senescence of cervical cancer cells and to explore the potential of an antisense RNA (AS) transcript for gene therapy of cervical cancer. The antisense RNA directed against HPV-16 E6 and E7 (16AS) was constructed, and its effects on cell apoptosis and senescence of SiHa cervical carcinoma cells harboring HPV-16 were analyzed. The efficiency of 16AS was evaluated with RT-PCR, Western blotting, flow cytometry analysis, Hoechst 33258 staining, senescent cell morphology observation and senescence-associated beta-galactosidase staining. The sufficient repression of HPV-16 E6 and E7 oncogenes were achieved in 16AS-transfected SiHa cells, which led to obvious apoptosis and replicative senescence of tumor cells. Furthermore, the downregulation of HPV-16 E6 and E7 by 16AS transfection resulted in remarkable increase of both p53 expression and hypophosphorylated p105Rb level in SiHa cells. These results demonstrate that reduction of E6 and E7 expression is sufficient to induce SiHa cells to undergo apoptosis and senescence and suggest that transfection of cervical cancer cells with HPV-16 E6 and E7 antisense RNA is a potential approach to treat HPV-16-positive cervical cancers.

    Full Text Available Abstract Background Human papillomavirus (HPV 16 and 18 are associated with cervical carcinogenesis through an interaction between HPV oncogenic proteins and cell cycle regulatory genes. However, the exact pathogenetic mechanisms are not determined yet. Methods We investigated 43 invasive squamous cell carcinoma (ISCC, 38 CIN III, 11 CINII and 18 CINI for cyclin D1, cyclin E, CDK4, p53, mdm-2, p21waf, p27, p16INK4A, Rb and Ki-67 aberrations using immunohistochemistry and molecular techniques. Twenty samples of normal cervical tissues (NCT were taken as a control. Results There was a significant increase in the expression of Ki-67, cyclin E, CDK4, p16INK4A, Rb (p= 0.003, 0.001, 0.001, 0.01 and a significant decrease in p27KIP1 from NCT to ISCC (p = 0.003. Increased cyclin D1, p21waf, p53, mdm-2 expression, homozygous deletion (HZD and promoter methylation (PM of the Rb were detected in CINIII and ISCC only. On univariate analysis; tumor size, differentiation, lymph node status, FIGO stage, Ki- 67, cyclin D1, p53 and p27KIP1 are significantly associated with reduced overall survival (OS while on multivariate analysis; only FIGO stage, Ki-67, cyclin D1, p53 and p27KIP1 were significant. Conclusion 1 Aberrations involving p27KIP1, cyclin E, CDK4, p16INK4A are considered early events in HPV 16 and 18-associated cervical carcinoma, whereas cyclin D1 and p53 pathway abnormalities are considered late events. 2 Immunohistochemical tests for p16INK4Aand cyclin E, could help in early diagnosis of cervical carcinoma. 3 Only FIGO stage p53, cyclin D1, p27KIP1 and Ki-67 are independent prognostic factors that might help in predicting outcome of cervical cancer patients.

    Full Text Available Pain in carcinoma cervix is a multidimensional experience with sensory, affective and cognitive-evaluative components. Many patients do not receive adequate pain management because of a lack of proper assessment, misconceptions regarding the pharmacologic and non pharmacologic methods of pain management and failure to distinguish between different types of pain. In our audit pelvic and nodal recurrence were the commonest cause of pain presenting as as pelvic pain, [42%], lumbosacral plexopathy [40%] and abdominal pain [34%] [n = 30]. Pain on defaecation caused by rectal obstruction, and suprapubic pain due to pyometra can be relieved by colostomy and drainage. Very little literature is available on the pain syndromes associated with carcinoma cervix. The present article is a review of cancer and treatment related pains in carcinoma cervix.

    This study was conducted to determine human papillomavirus (HPV) types in women with cervical cancer (CC) and normal cervical cytology in the Southern region of Mexico, and to know the contribution of HPV types and cofactors in cervical cancer etiology. A case-control study was performed in 133 women with CC and 256 controls. HPV detection was done by MY09/11 and GP5+/GP6+ PCR systems and typing by restriction fragment length polymorphism or DNA sequencing. HPV was found in 100% of CC and 35.5% of controls. The genotype distribution in CC was: HPV 16 (66.8%), 18 (9%), 31 (7.5%), 45 (4.5%), 58 (3.7%), 69 (3%), 52 (1.6%), 6, 11, 33, 56, and 67 (0.8% each). Among controls, HPV 33 followed by HPV 16 were the most frequent. Cervical cancer was associated with HPV 16 (OR=573.5), HPV 18 (OR=804.4), and undetermined risk HPV (types 67 and 69) (OR=434.3). Age at first intercourse or =3 births (OR=16) were significant risk factors for CC. HPV 16, by far, is the most frequent type in CC, HPV 16 and 18 are responsible for 75.8% of the CC cases and high-risk HPV for 94.7%, which is useful data to take into account in vaccination programs. HPV 33 is the most frequent type in controls and high-risk HPV are more common than low-risk HPV.

    Full Text Available Myoepithelial carcinoma (malignant myoepithelioma of the breast is a rare tumor, for which only a limited number of reports have been published. Most of the reports emphasized diagnosis and pathology but not biological behavior and treatment. We report a 61-year-old patient with breast myoepithelial carcinoma who developed locoregional and distant metastases and received many chemotherapy regimens. She presented with an elastic hard mass of the left breast. Breast conserving surgery was performed as part of both diagnosis and treatment. From the results of histological and immunohistochemical examinations, this case was considered to be a myoepithelial carcinoma. Fifteen months after the completion of adjuvant radiotherapy, distant metastasis of the left parasternal lymph node metastasis developed. She was treated by further excision and received a total of four regimens of chemotherapy including a combination of doxorubicin and cyclophosphamide. She received chemotherapy for 20 months after the diagnosis of metastasis.

    A unique case report. A three-dimensional (3D) printing technology is proposed for reconstructing multi-level cervical spine (C2-C4) after resection of metastatic papillary thyroid carcinoma in a middle-age female patient. Papillary thyroid carcinoma is a malignant neoplasm with a relatively favorable prognosis. A metastatic lesion in multi-level cervical spine (C2-C4) destroys neurological functions and causes local instability. Radical excision of the metastasis and reconstruction of the cervical vertebrae sequence conforms with therapeutic principles, while the special-shaped multi-level upper-cervical spine requires personalized implants. 3D printing is an additive manufacturing technology that produces personalized products by accurately layering material under digital model control via a computer. Reporting of this recent technology for reconstructing multi-level cervical spine (C2-C4) is rare in the literature. Anterior-posterior surgery was performed in one stage. Radical resection of the metastatic lesion (C2-C4) and thyroid gland, along with insertion of a personalized implant manufactured by 3D printing technology, were performed to rebuild the cervical spine sequences. The porous implant was printed in Ti6AL4 V with perfect physicochemical properties and biological performance, such as biocompatibility and osteogenic activity. Finally, lateral mass screw fixation was performed via a posterior approach. Patient neurological function gradually improved after the surgery. The patient received 11/17 on the Japanese Orthopedic Association scale and ambulated with a personalized skull-neck-thorax orthosis on postoperative day 11. She received radioiodine I therapy. The plane X-rays and computed tomography revealed no implant displacement or subsidence at the 12-month follow-up mark. The presented case substantiates the use of 3D printing technology, which enables the personalization of products to solve unconventional problems in spinal surgery. 5.

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Objective: To investigate the expression of aquaporin 1 in cervical squamous carcinomas (CSC) and cervical precancerous lesions, and the relationship between the tumor clinicopathological parameters, prognosis and the expression of AQP1. Methods: Immunohistochemical method (EliVision) was used to detect the expression of AQP1 in samples from 106 patients [20 with normal cervical tissue, 30 with cervical intraepithelial neoplasia (stage Ⅰ and Ⅱ) and 56 with CSC]. Survival analysis was performed by Kaplan-Meier method. Results: AQP1 protein was expressed in vascular endothelia of all samples. It showed upregulation of AQP1 expression in CSC. There was a significant difference between CSC and normal cervical tissues (P<0.05). AQP1 was expressed in some tumor cells and unexpressed in normal squamous epithelial cells. And APQ1-expressing tumor cells were positively related to lymph node metastasis. Patients with APQ1-expressing tumor cells had the lower survival rate than the ones without. Conclusion: Abnormal expression of AQP1 plays an important role in the development of CSC. Positive expression of AQP1 in tumor cells maybe enhances tumor metastasis and could be used as a marker for tumor prognosis.

    The aim of this study is to investigate cyclin E, pl6inkda and ki67 as possible diagnostic biomarkers for cervical preneoplasia using cervical exfoliated-cell specimens, and evaluate the significance for screening patients at high risk of developing cervical carcinoma. The expression of cyclin E, pl6inkda and ki67 was examinated in 78 cervical exfoliated epithelial specimens diagnosed as atypical squamous cells of undetermined significance (ASCUS) (12 cases), cervical intraepithelial neoplasia (CIN) of type 1 (17 cases), CIN2_3 (38 cases) and invasive carcinoma (11 cases) using immunohistochemical analysis, and simultaneously, the DNA status of human papillomavims (HPY) type 16/18 was detected by polymerase chain reaction (PCR) using type specific primers, cyclin E, pl6inkda and ki67 were all overexpressed in CINs and invasive carcinoma, compared with little expression in ASCUS ( P <0.005). Overexpression of cyclin E was observed in CIN1(94.1%, X2 = 21.16, P < 0.01), and p16inkda and ki67 were overexpressed in invasive carcinoma (100% and 90.9% respectively). The degree of pl6inkda and ki67 expression correlated well with that of epithelial lesions ( P < 0.005). HPV16/18 infection was assessed in C1Ns and invasive carcinoma samples, and revealed a significant relationship with the degree of cervical epithelial lession. The expression level of pl6inkda and ki67 seemed more closely associated with HPVI6 infection than that of cyclin E (rs= 1.0 vs rs=0.4). Only 1 case in CINI and d cases in CIN2-3 of HPV18 positive samples were detected. Therefore no statistical significance was found by statistical analysis. Overexpression of cyclin E, pl6inkda and ki67 in CINs and invasive carcinoma cells demonstrates the potential use of cyclin E, pl6inkda and ki67 as diagnostic biomarkers for HPV-related cervical neoplastic lesions. In addition, this technique can be used for screening patients at high risk of developing cervical carcinoma.

    A retrospective study was performed on 131 patients with stage 1B cervical carcinoma who were referred and treated with external beam radiation and intracavitary brachytherapy at the Division of Radiation Therapy, Department of Radiology, King Chulalongkorn Memorial Hospital between February 1985 and February 2000. Primary outcomes were overall survival rate, progression free survival rate, recurrence, and treatment-related complications. The treatment results from different sources of intracavitary radiation therapy were secondary endpoints. The number of patients treated with Ra-226, Cs-137, and Ir-192 intracavitary irradiation were 12, 84, and 35 patients respectively. The median follow-up times were 69, 59, and 21 months for Ra-226, Cs-137, and Ir-192, respectively. Actuarial 5-year overall survival rate was 89 per cent. The 5-year progression free survival rate was 80 per cent. Actuarial 5-year survival and progression free survival rate were comparable among different sources of intracavitary brachytherapy (p = 0.553 and p=0.793, respectively). The overall recurrent rate was 16.8 per cent. Of the recurrence; 40.9 per cent was locoregional, 54.6 per cent was distant failure, and 4.5 per cent was combined locoregional and distant failure. The overall complication rate was 25.95 per cent. The severe complication rates (Grade III-V) from treatment occurred in the urinary bladder (0.76%) and in the small bowel (0.76%.) These results suggest that radiation therapy alone is an effective treatment for stage 1B cervical carcinoma. Additionally, all types of intracavitary brachytherapy provide comparable clinical results.

    Background and Purpose: To date, no information is available concerning the impact of spinal anesthesia on the oxygenation status of carcinomas of the uterine cervix. The aim of this study was therefore to determine the influence of spinal anesthesia on the oxygenation status of cervical carcinomas. Patients and Methods: In ten patients with cervical carcinoma who received spinal anesthesia for a first application of brachytherapy, intratumoral pO{sub 2} measurements (pO{sub 2} histography system, Eppendorf-Netheler-Hinz, Hamburg, Germany) were performed. Systemic parameters were documented prior to and during spinal anesthesia. Patients breathed room air spontaneously. For further evaluation, all intratumoral pO{sub 2} values were pooled, and overall median pO{sub 2} values and fractions of hypoxic pO{sub 2} values {<=} 5 mm Hg were calculated. Overall median pO{sub 2} values in the subcutis were also calculated. Results: There were no significant changes of systemic parameters, median subcutaneous pO{sub 2} values, median intratumoral pO{sub 2} values, and the fractions of hypoxic pO{sub 2} values {<=} 5 mm Hg in the tumor upon administration of spinal anesthesia. The variability of measured pO{sub 2} values increased during spinal anesthesia, although substantial changes in the oxygenation status were only seen in individual cases (n = 2). Conclusion: This study shows for the first time that the oxygenation status of cervical carcinomas, in general, is not influenced by spinal anesthesia prior to application of brachytherapy. To conclude, the data presented suggest that reliable pO{sub 2} measurements can be performed under spinal anesthesia. At the same time, since no substantial changes in tumor oxygenation were observed, spinal anesthesia should not affect the O{sub 2}-related efficacy of high-dose-rate brachytherapy. (orig.)

    Cervical squamous carcinoma is a highly invasive tumour that has a great capacity to metastasise. Extracellular matrix metalloproteinase inducer (EMMPRIN or CD147), a member of the immunoglobulin superfamily, is a widely distributed cell surface glycoprotein. It is highly expressed on malignant tumour cell surfaces, including human cervical squamous carcinoma. It also plays a critical role in the invasive and metastatic activity of malignant cells by stimulating the expression of matrix metalloproteinases (MMPs). The anti-invasive effect of small interfering RNA (siRNA) against CD147 on human cervical squamous carcinoma cells and its possible pathways has been investigated. The downregulation of CD147 by transfection with siRNA resulted in MMP-9 expression and decreased activity in the cervical squamous carcinoma cell line SiHa. In vitro analysis showed that the invasive capacity of SiHa cells decreased. Thus CD147 inhibition and subsequent MMP-9 deletion may have anti-tumour effects by inhibiting the invasiveness of human cervical squamous carcinoma cells.

    AIM: To study the mechanism of Je-Chun-Jun (JCJ)-inducing the apoptosis of the human cervical carcinoma,HeLa cells. METHODS: The cell viability was assessed using MTT assay. The optical density was measured at 570 nm. The caspase activity was measured using 50 mmol/L of fluorogenic substrate, AC-DEVD-AMC (caspase3), AC-VEID-AMC (caspase-8) or AC-LEHD-AFC (caspase-9). To confirm the expression of proteins, Western blotting was performed. To detect the characteristic of apoptosis chromatin condensation, HeLa cells were stained with Hoechst 33258 in the presence of JCJ. For the cell cycle analysis, HeLa cells were incubated with Propidium iodide (PI) solution. Fluorescence intensity of cell cycle was measured using flow cytometry system. RESULTS:The loss of viability occurred following the exposure of 10 g/L JCJ. Cells treated with 10 g/L JCJ for 3 d exhibited the apoptotic morphology (brightly blue-fluorescent condensed nuclei by Hoechst 33258-staining) and the reduction of cell volume. Cells incubated with JCJ for 48 h were arrested at the G1 phase of cell cycle and their G1 checkpoint related gene products such as cyclin D1 were transiently decreased. We showed that JCJ induced the p38 MAPK activation in HeLa cells. The p38 MAPK inhibitor, SB203580 protected Hela cells from the JCJ-induced death as well as intervened the JCJ-induced accumulation of cells at the G1 phase. In contrast, MEK1 (-ERK upstream) inhibitor, PD98059 had no effect on HeLa cells. CONCLUSION: JCJ induced cell cycle arrest and apoptosis of HeLa cells through p38 MAPK pathway.

    Full Text Available This study assesses the morbidity and complications of treatment among long-term survivors of cervical cancer. Ninety-eight female patients who were diagnosed and treated from invasive carcinoma of the cervix uteri 5 years or more are included in this study. All the cases were free of disease and had survived up to December 2010. Forty-one cases were treated with radical hysterectomy with removal of the lymph nodes (Wertheim’s surgery (42%. Radical radiation therapy was given to 57 cases (58% according to our treatment protocol; weekly cisplatin was given concomitantly with radiation. Although urinary adverse effects were more prevalent among the radiation group, the difference was not statistically significant. Bowel dysfunction was more prevalent and statistically significant (p\\0.001 among the radiotherapy arm. Dysfunctions recorded included change in bowel habit, diarrhea, constipation, tenesmus, soiling of clothes and or flatulence. However, their severity was grade 1–2 only. The frequency of small intestinal obstruction was comparable in both arms. Pelvic vein thromboses had a tendency to occur among the surgical group especially in obese females (p value 0.005. The frequency of sexual dysfunction was comparable in both groups with no statistical difference. It was age related. The younger the patients’ ages, the more was the sexual complaint irrespective to the treatment modality. Sexual problems included dyspareunia from vaginal stenosis shortening or dryness, vulval soreness from itching and dryness. Bearing in mind that many patients had more than one health complaint. The remaining cases denied the presence of any complications and stated that they had a normal life style.

    High-dose-rate intracavitary brachytherapy (HDR-ICBT) for carcinoma of the uterine cervix often results in high doses being delivered to surrounding organs at risk (OARs) such as the rectum and bladder. Therefore, it is important to accurately determine and closely monitor the dose delivered to these OARs. In this study, we measured the dose delivered to the rectum by intracavitary applications and compared this measured dose to the International Commission on Radiation Units and Measurements rectal reference point dose calculated by the treatment planning system (TPS). To measure the dose, we inserted a miniature (0.1 cm{sup 3}) ionization chamber into the rectum of 86 patients undergoing radiation therapy for cervical carcinoma. The response of the miniature chamber modified by 3 thin lead marker rings for identification purposes during imaging was also characterized. The difference between the TPS-calculated maximum dose and the measured dose was <5% in 52 patients, 5-10% in 26 patients, and 10-14% in 8 patients. The TPS-calculated maximum dose was typically higher than the measured dose. Our study indicates that it is possible to measure the rectal dose for cervical carcinoma patients undergoing HDR-ICBT. We also conclude that the dose delivered to the rectum can be reasonably predicted by the TPS-calculated dose.

    Human cervical carcinoma cell lines that were either positive or negative for human papillomavirus (HPV) DNA sequences were analyzed for evidence of mutation of the p53 and retinoblastoma genes. Each of five HPV-positive cervical cancer cell lines expressed normal pRB and low levels of wild-type p53 proteins, which are presumed to be altered in function as a consequence of association with HPV E7 and E6 oncoproteins, respectively. In contrast, mutations were identified in the p53 and RB genes expressed in the C-33A and HT-3 cervical cancer cell lines, which lack HPV DNA sequences. Mutations in the p53 genes mapped to codon 273 and codon 245 in the C33-A and HT-3 cell lines, respectively, located in the highly conserved regions of p53, where mutations appear in a variety of human cancers. Mutations in RB occurred at splice junctions, resulting in in-frame deletions, affecting exons 13 and 20 in the HT-3 and C-33A cell lines, respectively. These mutations resulted in aberrant proteins that were not phosphorylated and were unable to complex with the adenovirus E1A oncoprotein. These results support the hypothesis that the inactivation of the normal functions of the tumor-suppressor proteins pRB and p53 are important steps in human cervical carcinogenesis, either by mutation or from complex formation with the HPV E6 and E7 oncoproteins.

  19. Papillary carcinoma of thyroid with an unusual coexistence of metastatic deposits and tuberculosis in the cervical lymph nodes

    Full Text Available Papillary carcinoma of the thyroid with clinically significant cervical lymphadenopathy is a common presentation (particularly in young patients, and it may be the first manifestation of disease. Occasionally, besides metastatic deposits, the cervical lymph nodes may harbor other diseases, and determining the etiology in such a case becomes critical for the institution of proper treatment and complete cure of the patient. Detection of tuberculous lymphadenitis and metastatic deposits by radiological and/or fine needle aspiration cytology methods may not be always easy and may be missed due to inherent defects of the techniques hence, histopathological examination still remains the final resort. We report a case of papillary carcinoma of the thyroid and its rare association with both metastatic deposits and tuberculosis of the contiguous cervical lymph node groups. We suggest that tuberculosis must always be borne in mind besides metastases while evaluating the enlarged neck nodes in papillary carcinoma of the thyroid.

    In cervical cancer, evidence for the existence of a tumor-suppressor gene on chromosome 11 has been generated from studies with somatic cell hybrids, chromosome microcell transfer, or deletion analysis of DNA markers. As suggested by somatic cell hybrids analysis, chromosome 11 harbors at least three distinctive tumor-suppressor genes, two on the short arm and one on the long arm. Loss of heterozygosity (LOH) analysis using 16 markers, 10 of which were microsatellite-based, placed the region of a putative tumor-suppressor gene to 11q22-24. Recently, 11q13 was assigned as another possible site on the basis of molecular rearrangements, deletions, and translocations, nonrandomly involving this region in four of eight cervical carcinoma cell lines. Abnormal chromosomes 11 were found in HeLa, SiHa, and Caski lines and in C33A, a human papilloma virus-negative cell line. 18 refs.

    2008-06-01

    Neck pain is one of the most prevalent and costly health problems in the United States. It remains a complex, subjective experience with a variety of musculoskeletal causes. Although, cervical collars are a seemingly benign intervention, they can have adverse effects, especially when used for longer periods of time. It is feared that a long period of immobilization, can result in atrophy-related secondary damage. Many physicians cite anecdotal evidence of their clinical utility and soft cervical collars are often prescribed by convention for patients complaining of neck pain. The use of cervical collars to treat neck pain is an area of controversy. This review article examines the current evidence and studies related to recommending cervical collars for neck pain of a variety of etiologies.

    2010-01-01

    Full Text Available OBJECTIVE: To investigate the clinicopathological significance of podoplanin expression in the intratumoral stroma and neoplastic cells of early stage uterine cervical cancer. MATERIALS AND METHODS: A total of 143 patients with clinical stage I and IIA uterine cervical carcinomas underwent surgery between 2000 and 2007. Clinicopathological data and slides associated with these cases were retrospectively reviewed. Immunodetection of podoplanin expression in histologic sections of tissue microarray blocks was performed using the monoclonal antibody D2-40. RESULTS: Expression of podoplanin was detected in neoplastic cells in 31/143 (21.6% cases, with 29/31 (93.5% of these cases diagnosed as squamous carcinoma. For all of the cases examined, the strongest signal for podoplanin expression was observed at the proliferating edge of the tumor nests. The rate of positive podoplanin expression for node-positive cases was lower than that of node-negative (18.9% vs. 22.6%, respectively. Furthermore, the rate of positive podoplanin expression in fatal cases was 10.5% vs. 21.6%, respectively. In 27/143 (18.8% cases, podoplanin expression was detected in fibroblasts of the intratumoral stroma, and this expression did not correlate with patient age, clinical stage, tumor size, histologic type, depth of infiltration, or vascular involvement. Moreover, expression of podoplanin in intratumoral stroma fibroblasts was only negatively associated with nodal metastasis. A greater number of fatal cases was observed among negative intratumoral stroma fibroblasts (15.5% vs. 3.7%, respectively, although this difference was not significant. CONCLUSIONS: These preliminary results suggest that podoplanin may have a role in host-tumor interactions and, as a result, may represent a favorable prognostic factor for squamous cervical carcinomas.

    Full Text Available INTRODUCTION: Cancer of the cervix uteri is the second most common cancer among women worldwide. The association of human papillomavirus (HPV infection with cervical carcinogenesis is well documented. This is a pilot study aiming to studying the prevalence and the pattern of Human Papilloma Virus Type 16 (HPV16 by immunostaining in the tissues of cervical carcinomas of Ethiopian women. METHODS: 20 specimens of uterine cervical carcinomas were studied histopathologically and immunohistochemically for HPV16. RESULTS: Histologically the specimens were classified as: Ten cases were Non Keratinized Squamous cell carcinoma (NKSCC, six cases were Keratinized Squamous Cell Carcinoma (KSCC and four cases were Adenocarcinoma (ADC. Immunohistochemistry study showed positivity in eleven cases (55%; seven cases (35% were non-keratinized squamous cell carcinoma; three cases (15% were keratinized squamous cell carcinoma and one case (5% belonged to the adenocarcinomas. CONCLUSION: This study reveals a significant detection of HPV in Ethiopian women by the use of advanced techniques such as Immunohistochemistry (IHC. The data of this study suggested that the marked expression of the HPV 16 was in the less differentiated uterine cervix carcinomas

    Genetic variation of antigen-processing machinery (APM) components has been shown to be associated with cervical carcinoma risk and outcome in a genetically homogeneous Dutch population. However, the role of APM component single nucleotide polymorphisms (SNPs) in genetically heterogeneous populations with different distributions of human papillomavirus (HPV) subtypes remains unclear. Eleven non-synonymous, coding SNPs in the TAP1, TAP2, LMP2, LMP7 and ERAP1 genes were genotyped in cervical carcinoma patients and healthy controls from two distinct Indonesian populations (Balinese and Javanese). Individual genotype and allele distributions were investigated using single-marker analysis, and combined SNP effects were assessed by haplotype construction and haplotype interaction analysis. Allele distribution patterns in Bali and Java differed in relation to cervical carcinoma risk, with four ERAP1 SNPs and one TAP2 SNP in the Javanese population showing significant association with cervical carcinoma risk, while in the Balinese population, only one TAP2 SNP showed this association. Multimarker analysis demonstrated that in the Javanese patients, one specific haplotype, consisting of the ERAP1-575 locus on chromosome 5 and the TAP2-379 and TAP2-651 loci on chromosome 6, was significantly associated with cervical carcinoma risk (global P = 0.008); no significant haplotype associations were found in the Balinese population. These data indicate not only that genetic variation in APM component genes is associated with cervical carcinoma risk in Indonesia but also that the patterns of association differ depending on background genetic composition and possibly on differences in HPV type distribution.

    Objective: To investigate the anti-tumor effect of curcumin on human cervical carcinoma HeLa cells in vitro and in vivo. Methods: (1) Human cervical carcinoma cell line HeLa was cultured in vitro. HeLa cells were treated with 5-50μmol/L curcumin for 24. 48, 72 h and the growth inhibition rates of HeLa cells were measured by MTT method. Cell apoptosis was inspected by electron microscopy and flow cytometry (FCM). (2) A transplanted tumor model by injecting HeLa cells into subcutaneous tissue of BABL/C mice was established and its growth curve was measured. 30 BABL/C mice with tumors were divided into 2 groups at random and 0.2 ml saline or 0.2 ml 250 μmol/L curcumin was injected into abdominal cavity respectively once everyday and lasted for ten days. The changes of tumor volume were measured continuously and tumor inhibition rate was calculated. At last the expressions of caspase-3 and bax protein in transplanted tumors were detected by immunohistochemistry. Results: (1) Curcumin inhibited the proliferation of Lela cells on a dose-depending manner. Apoptosis of cells could be observed by FCM. Partial cells presented the characteristic morphological changes of apoptosis under electron microseope. (2) When 1×107 HeLa cells were inoculated for each mouse, 100% of the mice developed growing tumors after seven days. An inhibition effect was observed in treatment group, and the inhibition rate of curcumin was 74.33%. The expressions of caspase-3 and bax in the transplanted tumors were increased in curcumin group. Conclusion: Curcumin is effective as an anti-cancer drug not only in vitro but also in vivo.

    Our aim was to identify novel genomic regions of interest and provide highly dynamic range information on correlation between squamous cell cervical carcinoma and its related gene expression patterns by a genome-wide array-based comparative genomic hybridization (array-CGH). We analyzed 15 cases of cervical cancer from KangNam St Mary's Hospital of the Catholic University of Korea. Microdissection assay was performed to obtain DNA samples from paraffin-embedded cervical tissues of cancer as well as of the adjacent normal tissues. The bacterial artificial chromosome (BAC) array used in this study consisted of 1440 human BACs and the space among the clones was 2.08 Mb. All the 15 cases of cervical cancer showed the differential changes of the cervical cancer-associated genetic alterations. The analysis limit of average gains and losses was 53%. A significant positive correlation was found in 8q24.3, 1p36.32, 3q27.1, 7p21.1, 11q13.1, and 3p14.2 changes through the cervical carcinogenesis. The regions of high level of gain were 1p36.33-1p36.32, 8q24.3, 16p13.3, 1p36.33, 3q27.1, and 7p21.1. And the regions of homozygous loss were 2q12.1, 22q11.21, 3p14.2, 6q24.3, 7p15.2, and 11q25. In the high level of gain regions, GSDMDC1, RECQL4, TP73, ABCF3, ALG3, HDAC9, ESRRA, and RPS6KA4 were significantly correlated with cervical cancer. The genes encoded by frequently lost clones were PTPRG, GRM7, ZDHHC3, EXOSC7, LRP1B, and NR3C2. Therefore, array-CGH analyses showed that specific genomic alterations were maintained in cervical cancer that were critical to the malignant phenotype and may give a chance to find out possible target genes present in the gained or lost clones.

    The subject of this case report was a 56-year-old woman who sustained a whiplash-associated disorder as a result of a motor vehicle accident. Within a few hours after the accident, she developed a headache, which became chronic, creating disability and hindering the quality of her life. In the following year, a variety of diagnostic tests, medications, and physical therapy were unsuccessful in determining the cause of her complaints or in relieving them. After this year, she expressed anger, frustration, and a reluctance to undergo additional physical therapy. By listening to her explain how she coped with her problem and observing that she lacked the ability to reduce her cervical lordosis, the therapist developed and implemented a home program of supine cervical traction and exercise. After 30 days of treatment, she was able to reduce and control her headache. This treatment and the approach used to develop the treatment may benefit other patients who have whiplash-associated chronic headache.

    2009-01-01

    Objective Background-study on genesis and development of tumor is mainly concentrated on gene mutation in nucleus. In recent years, however, the role of mitochondrial DNA (mtDNA) mutation in tumor genesis has been given more and more attention, which is the only extra-nucleus DNA in cells of higher animals. Carcinoma of the uterine cervix is a common tumor in gynecology, but there are few reports of mtDNA mutation in this area. The focus of this study was to investigate the mtDNA mutation in tumor tissues of cervical carcinomas and their relationship to tumorigenesis and tumor development. Methods The D-loop region of 24 cervical carcinomas together with the adjacent normal tissues were amplified by PCR and sequenced. Results Among the 24 cervical carcinomas, 30 mutations in 9 patients′ specimen were identified with the mutations rate of 37.5%(9/24). There were 8 microsatellite instabilities among the mutations and 13 new polymorphisms which were not reported previously in the Genbank. Conclusions The D-loop region of mitochondrial DNA is a highly polymorphoric and mutable region and the mutation rate is relatively high in patients with cervical carcinomas.

    A 15-year-old girl was diagnosed with osteosarcoma; limb salvage surgery was performed after preoperative chemotherapy. Postoperatively, adjuvant chemotherapy was given for 2 years. One year after completion of chemotherapy, the patient was readmitted for systemic recurrence. Amputation of the lower extremity and wedge resection of lung metastasis were performed followed by combination chemotherapy. Two years after cessation of chemotherapy, ulcer of the tongue was noted and cervical lymph nodes were detected by palpation. Biopsy of the lesion showed squamous cell carcinoma. The patient underwent a radical partial tongue resection and postoperative irradiation, followed by chemotherapy. Six years after treatment for the second malignancy, the patient remains well without evidence of disease. Squamous cell carcinoma of the tongue as a second malignancy after treatment of osteosarcoma is quite rare. Long-term follow-up, with particular attention to the head and neck, may be warranted in children treated for osteosarcoma.

    Radiofrequency ablation (RFA) recently has been applied to benign thyroid nodules, mainly for the cosmetic reasons, and limited cases of local recurrences or focal distant metastases of well-differentiated thyroid cancer, in the high-risk reoperative condition or for the palliative purpose. But no report has been made on the RFA for primary thyroid cancer to date. We report on a patient with primary papillary carcinoma of thyroid gland who had undergone RFA before the cytological diagnosis of malignancy, later referred and treated with robotic surgery successfully. We can learn the following lessons from our case; (1) the RFA for operable primary thyroid malignancy should be avoided, because of the possibility of remnant viable cancer and undetectable nodal metastasis, and (2) robotic or endoscopic thyroid surgery may be a feasible operative method for benign or malignant thyroid nodules previously treated with RFA.

We report on a patient with primary papillary carcinoma of thyroid gland who had undergone RFA before the cytological diagnosis of malignancy, later referred and treated with robotic surgery successfully. We can learn the following lessons from our case; (1 the RFA for operable primary thyroid malignancy should be avoided, because of the possibility of remnant viable cancer and undetectable nodal metastasis, and (2 robotic or endoscopic thyroid surgery may be a feasible operative method for benign or malignant thyroid nodules previously treated with RFA.

    Interstitial collagenase and gelatinases are matrix metalloproteinases (MMP), which play the key role in tumor invasion and metastasis. The aim of this study was to elucidate the peculiarities of expression of interstitial collagenase (MMP-1), gelatinases A and B (MMP-2 and MMP-9) and their endogenous tissue inhibitors TIMP-1 and TIMP-2 as invasive factors of squamous cell carcinomas (SCC) of human cervical cancer. The study was carried out using 24 specimens of SCC and 11 specimens of adjacent to tumor morphologically normal tissue. All carcinoma specimens expressed E7 HPV-16 gene. It was shown that the increase of MMP-1 and MMP-9 expression and low of TIMP-1 and TIMP-2 expression makes the main contribution to the destructive (invasive) potential of SCC. The change of MMP-2 expression is not so significant and it is less influenced to the destructive potential. Moreover, substantial expression of MMP-1, MMP-2 and MMP-9 was registered in the specimens of morphologically normal adjoining to tumor tissue. This expression was found to make an additional contribution to the destructive potential of cervical tumor.

    To determine the diagnostic accuracy of CT for the detection of cervical lymph node metastases in patients with papillary thyroid carcinoma (PTC). Two hundred twelve consecutive patients with surgically proven PTC were included in this study. CT images were retrospectively evaluated to determine the presence of a node metastasis using morphologic CT criteria (at least one of the following: strong nodal enhancement without hilar vessel enhancement, heterogeneous enhancement, calcification, and cystic change). The diagnostic accuracy of CT for the diagnosis of a metastatic lymph node was assessed using a level-bylevel analysis. The accuracy of the CT finding for strong nodal enhancement was greater than the other morphologic CT criteria (81.6% and 74.5-78.5%, respectively). The sensitivity, specificity, and accuracy were 64.4%, 91.4%, and 84.3% by the morphologic CT criteria, and were 34.6%, 93.9%, and 78.2% by size criteria, respectively. The morphologic CT criteria are more accurate than the size criteria in the detection of cervical lymph node metastases in patients with papillary thyroid carcinoma; and, strong nodal enhancement on a CT scan is the most important factor for its diagnostic accuracy.

    Objective: To explore the effect of bortezomib on migration and invasion of cervical carcinoma HeLa cell and specific molecular mechanism. Methods:The effect of bortezomib on the viability of HeLa cell was measured by MTT assay. The effect of bortezomib on cell migration and invasion was measured by Transwell assay and invasion experiment respectively. The activation of Akt/mTOR signaling pathway and expression level of MMP2, MMP9 were assayed by western blot. Results:MTT assay indicated bortezomib (2.5μM, 5μM, 10μM) could inhibit HeLa cell viability, and the inhibitory rate was highest at 48 h. Transwell assay and invasion experiment results showed that bortezomib inhibited HeLa cell migration and invasion. Western blotting assays presented bortezomib could suppress the phosphorylation of Akt and mTOR, and down-regulate the expression of MMP2 and MMP9. Conclusions:These results suggested bortezomib could inhibit migration and invasion in cervical carcinoma HeLa cell, which might be related to Akt/mTOR signal pathway.

    OBJECTIVE To study the expression level and clinical significance of HMGB1 and RAGE in cervical squamous epithelial carcinoma.METHODS Real time quantitative polymerase chain reaction (qRT-PCR)was employed to examine the expression of HMGB1 (high mobility group box protein1), and RAGE (receptor for advanced glycation endproducts)in 60 cervical squamous epithelial carcinomas (CSEC), their paraneoplastic tissues (PS) and 30 normal cervix tissues (NCS).RESULTS The expression of HMGB1 in the CSEC samples and PS was similar (P>0.05), but higher compared to NCS (P<0.05). Overexpression of HMGB1 in the CESC tissues was significantly correlated with the tumor (P<0.05), and the presence of metastasis (P<0.01), but not correlated with the tumor diameter or tumor grade. RAGE expression was not significantly different among these tissue types, and showed no significant correlation with the the tumor stage, diameter or grade. But there was a significant positive correlation between RAGE expression and CSEC metastasis.CONCLUSION The results suggest that HMGB1 may be related to the proliferation, progression and metastasis of CSEC. The relationship of HMGB1/RAGE may be of importance for CSEC metastasis. HMGB1 presents a new potential gene target for prevention and treatment of CSEC.Study of HMGB1/RAGE expression will offer an experimental foundation for understanding the pathogenesis of CSES.

    Overexpression of clusterin (CLU), an antiapoptotic molecule, has been reported to induce resistance to radiotherapy (RT) in a variety of cancer cell types. The aim of this study was to evaluate the significance of CLU expression to predict survival of patients with advanced-stage cervical cancer who received curative intended RT. Biopsy tissue specimens of advanced-stage cervical cancer before curative intended RT were obtained from 34 patients who were treated at Hokkaido University Hospital between 1998 and 2008 and whose complete medical records were available. The expression of CLU protein was analyzed by immunohistochemistry. Findings were evaluated in relation to several clinicopathological factors. Survival analyses were performed using the Kaplan-Meier curves and the log-rank test. Independent prognostic factors were determined by multivariate Cox regression analysis. Clusterin protein was mainly present in the cytoplasm of cervical cancer cells. The expression of CLU protein in cervical cancer tissues before curative intended RT was not significantly related to any clinicopathological factors analyzed, including age, clinical stage, histologic type, and response to RT. Univariate analysis on prognostic factors showed that histologic type (P = 0.001), and CLU expression (P = 0.02) were related to survival. Multivariate analysis revealed that both histologic type (P = 0.002), and CLU expression (P = 0.02) were independent prognostic factors for overall survival. We conclude that CLU could be a new molecular marker to predict overall survival of patients with advanced-stage cervical cancer treated with curative intended RT.

    Purpose: To assess practice patterns and compliance with clinical performance measures for radiation therapy (RT) for patients with intact carcinoma of the cervix. Methods and Materials: Trained research associates reviewed the records of 261 randomly selected patients who received RT for cervix carcinoma between 2005 and 2007 from 45 facilities randomly selected after stratification by practice type. National estimates of patient and treatment characteristics were calculated from survey data using SUDAAN statistical software. Results: From the survey data, we estimated that only 8% of US facilities treated on average more than 3 eligible patients per year. No small or medium nonacademic facilities in the survey treated more than 3 eligible patients per year. Approximately 65.5% of patients began treatment in a facility that treated 3 or fewer eligible patients per year. Although 87.5% of patients had brachytherapy as part of their treatment, the proportion treated with external beam RT only was about double that estimated from the 1996 to 1999 survey. The use of high-dose-rate brachytherapy sharply increased, particularly in small nonacademic facilities. Overall, patients treated in nonacademic facilities were more likely to have incomplete or protracted treatment; 43% of patients treated in small nonacademic facilities did not have treatment completed within 10 weeks. Also, patients treated in facilities that treated 3 or fewer eligible patients per year were significantly less likely to receive concurrent chemotherapy than were patients treated in other facilities. Conclusion: Survey results indicate a disturbingly high rate of noncompliance with established criteria for high-quality care of patients with cervical cancer. Noncompliance rates are particularly high in nonacademic facilities, especially those that treat relatively few patients with intact cervical cancer.

    Cervical cancer has been identified as the third leading cause of average years of life lost per person dying of cancer. Since essentially all cervical cancers contain copies of human papillomavirus (HPV) DNA, we propose a treatment that targets HPV-infected cells using strategies that re-introduce normal functions into the infected cells while sparing healthy cells. We propose the use of focused ultrasound in combination with microbubbles as means to deliver antibodies against the E6 protein present only in HPV positive cells. We conducted in vitro studies with cell cultures of SiHa cervical carcinoma cells seeded into Opticell™ chambers. An in-house ultrasound excitation apparatus was used to control and explore the optimal acoustic parameters in order to maximize delivery. We first validated the possibility of delivering the EX-EGFP-M02 vector (Genecopoeia) into the cells; 1.2 μL of activated microbubbles (Definity®) and 50 μg of the vector were mixed in media and then injected into the Opticell™ chamber. We used 32 μs pulses at a central frequency of 930 KHz with a repetition frequency of 1.5 kHz and total exposure duration of 30 s; six pressure values were tested (0 to 1 MPa). Fluorescence imaging was used to determine the levels of intracellular proteins and assess delivery. The delivery of an anti-α-Tubulin antibody was next tested and confirmed that the delivery into HPV16 positive cells was successful.

    To assess the changes in cell kinetics during radiotherapy (RT) in terms of the MIB1 and PC10 labeling indexes of cancer cells, a total of 230 biopsy specimens taken from 76 consecutive patients with cervical squamous cell carcinoma treated with RT was investigated. The MIB1 and PC10 indexes represent the growth fraction and proliferative activity, respectively. The MIB1 index ranged from 11 to 67% (mean value: 38%) before RT, from 21 to 86% (50%) at 5.4 Gy, from 15 to 85% (53%) at 9 Gy, and from 0 to 69% (26%) at 27 Gy. The PC10 index ranged from 4 to 46% (23%) before RT, from 5 to 62% (26%) at 5.4 Gy, from 6 to 63% (23%) at 9 Gy, and from 0 to 35% (11%) at 27 Gy. The correlational relationships between the increment of both indexes during RT ({Delta} index) and the index before RT were analyzed on an individual basis. The {Delta} index was calculated by the index at various doses during RT minus the index before RT. Negative linear relationships were observed between the {Delta} MIB1 index at 9 Gy or {Delta} MIB1 index at 27 Gy and the MIB1 before RT, and also between the {Delta} PC10 index at 9 Gy or {Delta} PC10 index at 27 Gy and the PC10 index before RT. The linear regression coefficient values showed more than 0.5 (0.511 to 0.682) with statistical significance. According to these results, it was suggested that the cervical cancers of lower proliferative activity showed greater increases in growth fraction and proliferative activity by irradiation than those of higher proliferative tumors. These findings suggest that reversal patterns of changes in cell kinetics including growth fraction and proliferative activity took place in the early period of RT for cervical squamous cell carcinomas. The study of changes in cell cycle kinetics in human tumors during RT may have potential impact on the further development of RT. (orig.).

    Repression of human papillomavirus (HPV) E6 and E7 oncogenes in established cervical carcinoma cell lines causes senescence due to reactivation of cellular tumor suppressor pathways. Here, we determined whether ongoing expression of HPV16 or HPV18 oncogenes is required for the proliferation of primary human cervical carcinoma cells in serum-free conditions at low passage number after isolation from patients. We used an SV40 viral vector expressing the bovine papillomavirus E2 protein to repress E6 and E7 in these cells. To enable efficient SV40 infection and E2 gene delivery, we first incubated the primary cervical cancer cells with the ganglioside GM1, a cell-surface receptor for SV40 that is limiting in these cells. Repression of HPV in primary cervical carcinoma cells caused them to undergo senescence, but the E2 protein had little effect on HPV-negative primary cells. These data suggest that E6 and E7 dependence is an inherent property of human cervical cancer cells. Copyright © 2011 Elsevier Inc. All rights reserved.

    Aberrant methylation of tumor suppressor gene promoters has been extensively investigated in cervical cancer. Transcriptional silencing, as a main consequence of hypermethylation of CpG islands, is the predominant mechanism of p16(INK4a) and E-cadherin gene inactivation in malignant epithelial tumors. This study was conducted to evaluate the promoter methylation status of p16(INK4a) and E-cadherin genes in 22 specimens of cervical carcinomas, four cervical cancer cell lines (HeLa, SiHa, Caski, C33A), and 20 human papillomavirus negative specimens, obtained from normal cervical swabs, using the methylation-specific PCR approach. Hypermethylation of the 5' CpG island of the p16(INK4a) and E-cadherin genes were found in 13 (59.1%) and 10 (45.5%) of 22 cervical cancer samples, respectively. Furthermore, our findings did not show any correlation between promoter methylation of p16(INK4a) and E-cadherin genes and clinicopathological parameters, including HPV infection, phenotypic distribution, and stage of the disease. However, hypermethylation of E-cadherin gene promoter appears to be age related in cervical cancer, whereas the frequency of aberrant methylation of p16(INK4a) gene promoter is unchanged according to the age of patients. Thus, caution must be made to use these markers in the diagnosis of cervical cancer. However, dietary or pharmaceutical agents that can inhibit these epigenetic events may prevent or delay the development of cervical cancer.

    Aberrant activation of the Wnt/β-catenin signaling pathway is common in human cervical cancers and has great potential therapeutic value. We show that tigecycline, a FDA-approved antibiotic drug, targets cervical squamous cell carcinoma through inhibiting Wnt/β-catenin signaling pathway. Tigecycline is effective in inducing apoptosis, inhibiting proliferation and anchorage-independent colony formation of Hela cells. The inhibitory effects of tigecycline are further enhanced upon combination with paclitaxel, a most commonly used chemotherapeutic drug for cervical cancer. In a cervical xenograft model, tigecycline inhibits tumor growth as a single agent and its combination with paclitaxel significantly inhibits more tumor growth throughout the duration of treatment. We further show that tigecycline decreases level of both cytoplasmic and nuclear β-catenin and suppressed Wnt/β-catenin-mediated transcription through increasing levels of Axin 1 in Hela cells. In addition, stabilization or overexpression of β-catenin using pharmacological and genetic approaches abolished the effects of tigecycline in inhibiting proliferation and inducing apoptosis of Hela cells. Our study suggests that tigecycline is a useful addition to the treatment armamentarium for cervical cancer and targeting Wnt/β-catenin represents a potential therapeutic strategy in cervical cancer. - Highlights: • We repurposed the antibiotic drug tigecycline for cervical cancer treatment. • Tigecycline is effectively against cervical cancer cells in vitro and in vivo. • Combination of tigecycline and paclitaxel is synergistic in targeting Hela cells. • Tigecycline acts on Hela cells through inhibiting Wnt/β-catenin signaling.

    Purpose: To compare clinical behaviors and treatment outcomes between patients with squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) of the cervix treated with radical hysterectomy (RH) and adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT). Methods and Materials: A total of 318 Stage IB-IIB cervical cancer patients, 202 (63.5%) with SCC and 116 (36.5%) with AC/ASC, treated by RH and adjuvant RT/CCRT, were included. The indications for RT/CCRT were deep stromal invasion, positive resection margin, parametrial invasion, or lymph node (LN) metastasis. Postoperative CCRT was administered in 65 SCC patients (32%) and 80 AC/ASC patients (69%). Patients with presence of parametrial invasion or LN metastasis were stratified into a high-risk group, and the rest into an intermediate-risk group. The patterns of failure and factors influencing survival were evaluated. Results: The treatment failed in 39 SCC patients (19.3%) and 39 AC/ASC patients (33.6%). The 5-year relapse-free survival rates for SCC and AC/ASC patients were 83.4% and 66.5%, respectively (p = 0.000). Distant metastasis was the major failure pattern in both groups. After multivariate analysis, prognostic factors for local recurrence included younger age, parametrial invasion, AC/ASC histology, and positive resection margin; for distant recurrence they included parametrial invasion, LN metastasis, and AC/ASC histology. Compared with SCC patients, those with AC/ASC had higher local relapse rates for the intermediate-risk group but a higher distant metastasis rate for the high-risk group. Postoperative CCRT tended to improve survival for intermediate-risk but not for high-risk AC/ASC patients. Conclusions: Adenocarcinoma/adenosquamous carcinoma is an independent prognostic factor for cervical cancer patients treated by RH and postoperative RT. Concurrent chemoradiotherapy could improve survival for intermediate-risk, but not necessarily high-risk, AC/ASC patients.

    Full Text Available Purpose: In clinical practice, radiation therapy often fails in cervical carcinoma stage IIIB and there is a need to develop a predictive assay for prognosis of radiation treatment outcome in cancer patient. We have attempted to evaluate the relevance of changes in Membrane Fluidity (MF and associated apoptotic cell death in cervical cancer cells after first fractionated dose of radiation therapy to treatment outcome of stage IIIB cervical carcinoma patients. Materials and Methods: Biopsies of 15 patients with histologically proven cervix cancer were collected from the patients before and 24 h after first fractionated radiation dose of 2 grays (Gy. Cell suspension made in Dulbecco′s Modified Eagle′s Medium (DMEM were used for further investigations and cell suspension of cervix cancer patient were used to measure MF by fluorescence polarization method and apoptotic index (AI was determined by Tdt dUTP Nucleotide End Labeling (TUNEL assay. Results: A substantial increase in MF and AI was observed in cervical cancer cells irradiated ex vivo . A significant correlation ( P < 0.001 was found between the changes in AI after first fractionated dose of radiotherapy and treatment outcome of patients. No significant correlation ( P > 0.1 was detected between changes in MF and treatment outcome of patients. Conclusion: Preliminary results showed significant change in MF and a marked increase in percentage apoptosis of cervix cancer cells irradiated ex vivo . The changes in AI after first fractionated dose of radiotherapy in cervical carcinoma patients may provide a predictor of prognosis for radiotherapy in uterine cervical carcinoma patients.

    Upper back pain originating from the cervical disk itself is defined as cervical discogenic upper back pain. Coblation procedures can provide therapeutic effects for neck and radicular pain related to contained cervical disk herniation. However, no studies have reported the performance of coblation procedures, particularly for treating cervical discogenic upper back pain. The purpose of this study was to evaluate the efficacy of coblation procedures in treating cervical discogenic upper back pain.In a prospective, clinical, observational study, 28 consecutive patients with discogenic upper back pain underwent coblation procedures on the cervical disk with a percutaneous anterior approach. Pain visual analogue scale (VAS) scores, patient responses stating significant (≥50%) pain relief, significant (≥50%) reduction in pain medicine intake and Modified MacNab criteria were adopted to evaluate the pain intensity, degree of pain relief, and functional status after 12 months of follow-up.The preoperative pain VAS score was 6.5 ± 1.1 (95% confidence interval [CI] 6.085-6.915), and the pain VAS score significantly decreased to 2.4 ± 1.3 (95% CI 1.929-2.928), 2.5 ± 1.5 (95% CI 1.963-3.109), 2.7 ± 1.4 (95% CI 2.157-3.271), 3.1 ± 1.6 (95% CI 2.457-3.686), and 3.1 ± 1.6 (95% CI 2.471-3.743) at 1 week and 1, 3, 6, and 12 months postoperatively, respectively (P coblation is an effective, safe, minimally invasive, and less uncomfortable procedure for the treatment of discogenic upper back pain.

    Full Text Available Background and Purpose: Cervical disc prolapse is one of the leading cause of morbidity and affecting the patients routine work of their ADL. Due to severity of symptoms and patients feeling of insecurity, physiotherapeutic conservative approach is questionable and has become challengeable against surgery. The purpose of this case report is to explore the efficacy of multimodal physiotherapeutic approach in treating a patient with acute cervical disc prolapse. Case Description: 33 year old male patient was diagnosed with acute cervical disc prolapse and the pain was radiating to the right upper limb associated with numbness. The patient was given initially physiotherapeutic modalities like cryotherapy, ultrasound and mechanical traction to reduce pain. Muscle Energy Technique was also implemented for initial days along with cryotherapy based on cryokinetics concept to enhance movements of cervical spine. Mckenzie exercises with appropriate techniques was administered for 10 days along with retraction exercise, basic ROM and neck isometrics as a home program. The patient received treatment for a period of 12 days. Outcome Measures: The outcome measures used were Numeric Pain Rating Scale, Neck Disability Index, Tampa Scale for Kinesiophobia, and Cervical ROM. Conclusion: Multimodal physiotherapeutic approach along with Mckenzie technique played a significant role in alleviating pain, numbness and improvement of the patient functionally for return to his normal work.

    To establish an animal model of spontaneous cervical lymph node metastasis of laryngeal squamous cell carcinoma and obtain laryngocarcinoma cells with high metastatic potential, laryngeal squamous cell carcinoma cell line HEP-2 in logarithmic phase were inoculated under the lingual margin mucosa of nude mice. HEP-2 cells metastasized to the cervical lymph nodes were isolated, cultured, and re-inoculated under the lingual margin mucosa of nude mice twice. The tumor formation in the tongue and in the cervical lymph nodes was confirmed by pathological examination. Carcinoma cells' ability of invasion and migration was detected by transwell assay. Human specific Alu sequences were detected by PCR, which indicated that the tumor cells originated from human laryngeal squamous cell carcinoma cell line HEP-2. Finally, an animal model of spontaneous lymph node metastasis of laryngeal squamous cell carcinoma was successfully established. Laryngeal squamous cell carcinoma cells with high metastatic potential to lymph nodes were obtained through repeated inoculations. .

    Cervical sample is routinely taken to identify squamous dysplastic lesions of the cervix. Glandular lesions are far less commonly reported on cervical samples. The most common glandular lesion reported on cervical smear is endocervical adenocarcinoma, followed by endometrial adenocarcinoma. Direct sampling by Cervex brush is possible even in endometrial adenocarcinoma, if the tumor directly involves lower uterine segment/endocervical canal. Metastases to cervix are rare but have occasionally been reported in previous reports. We wish to highlight in this case, metastatic ovarian carcinoma directly sampled in cervical liquid-based cytology (LBC) sample, which mimicked cytomorphologically a well-differentiated endocervical adenocarcinoma. To the best of our knowledge, a similar case has not been previously published in SurePath LBC sample. PMID:25538388

    Full Text Available Abstract Background While the association of human papillomavirus (HPV with cervical cancer is well established, the influence of HIV on the risk of this disease in sub-Saharan Africa remains unclear. To assess the risk of invasive cervical carcinoma (ICC associated with HIV and HPV types, a hospital-based case-control study was performed between September 2004 and December 2006 in Kampala, Uganda. Incident cases of histologically-confirmed ICC (N=316 and control women (N=314, who were visitors or care-takers of ICC cases in the hospital, were recruited. Blood samples were obtained for HIV serology and CD4 count, as well as cervical samples for HPV testing. HPV DNA detection and genotyping was performed using the SPF10/DEIA/LiPA25 technique which detects all mucosal HPV types by DEIA and identifies 25 HPV genotypes by LiPA version 1. Samples that tested positive but could not be genotyped were designated HPVX. Odds ratios (OR and 95% confidence intervals (CI were calculated by logistic regression, adjusting for possible confounding factors. Results For both squamous cell carcinoma (SCC and adenocarcinoma of the cervix, statistically significantly increased ORs were found among women infected with HPV, in particular single HPV infections, infections with HPV16-related types and high-risk HPV types, in particular HPV16, 18 and 45. For other HPV types the ORs for both SCC and adenocarcinoma were not statistically significantly elevated. HIV infection and CD4 count were not associated with SCC or adenocarcinoma risk in our study population. Among women infected with high-risk HPV types, no association between HIV and SCC emerged. However, an inverse association with adenocarcinoma was observed, while decrease in CD4 count was not associated with ICC risk. Conclusions The ORs for SCC and adenocarcinoma were increased in women infected with HPV, in particular single HPV infections, infections with HPV16- and 18-related types, and high-risk HPV types

    A close relationship exists between immune response and tumor behavior. This study aimed to explore the associations between radiation-induced apoptosis (RIA) in peripheral blood lymphocytes (PBL) and clinical pathological variables. Furthermore, it assessed the role of RIA as a prognostic factor for survival in cervical carcinoma patients. Between February 1998 and October 2003, 58 consecutive patients with nonmetastatic, localized stage I-II cervical carcinoma who had been treated with radiotherapy (RT) ± chemotherapy were included in this study. Follow-up ended in January 2013. PBL subpopulations were isolated and irradiated with 0, 1, 2 and 8 Gy then incubated for 24, 48 and 72 h. Apoptosis was measured by flow cytometry and the ss value, a parameter defining RIA of lymphocytes, was calculated. Mean follow-up duration was 111.92 ± 40.31 months. Patients with lower CD8 T lymphocyte ss values were at a higher risk of local relapse: Exp(B) = 5.137, confidence interval (CI) 95 % = 1.044-25.268, p = 0.044. Similar results were observed for regional relapse: Exp(B) = 8.008, CI 95 % = 1.702-37.679, p = 0.008 and disease relapse: Exp(B) = 6.766, CI 95 % = 1.889-24.238, p = 0.003. In multivariate analysis, only the CD8 T lymphocyte ss values were found to be of prognostic significance for local disease-free survival (LDFS, p = 0.049), regional disease-free survival (RDFS, p = 0.002), metastasis-free survival (MFS, p = 0.042), disease-free survival (DFS, p = 0.001) and cause-specific survival (CSS p = 0.028). For the first time, RIA in CD8 T lymphocytes was demonstrated to be a predictive factor for survival in cervical carcinoma patients. (orig.)

    We wanted to determine the clinical characteristics and prognosis according to the VEGF expression in stage II cervical carcinoma patients treated with definitive radiotherapy. We enrolled 31 patients who were diagnosed with cervical cancer from 1995 to 2003 at Samsumg Medical Center and their paraffin block tissue samples were available for study. The median age of the patients was 65 years. The mean tumor size was 4.1 cm (range: 1.2 {approx}8.2 cm). Seven patients (22.6%) were suspected of having pelvic lymph node metastasis. An external beam irradiation dose of 45-56.4 Gy was administered to the whole pelvis with a 15 MV linear accelerator, and an additional 24 Gy was given to point A by HDR intracavitary brachytherapy. VEGF staining was defined as positive when more than 10% of the tumor cells were stained. The median follow-up duration was 58 months. A positive VEGF expression was observed in 21 patients (67.7%). There was no significant correlation between the VEGF expression and pelvic lymph node metastasis, tumor size and the response of radiotherapy. During follow-up, 7 patients had recurrence. The complete response rate was not significant between the VEGF (-) and VEGF(+) tumors. However, the VEGF(+) tumors showed a significantly higher recurrence rate in comparison with the VEGF(-) tumors ({rho} = 0.040). The three year disease-free survival rates were 100% and 66.7%, respectively, for patients with VEGF(-) or VEGF(+) tumor ({rho} = 0.047). The VEGF expression was a significant factor for recurrence and disease-free survival. However, the significance of the VEGF expression is still controversial because of the various definitions of VEGF expression and the mismatches of the clinical data in the previous studies.

    Purpose: This work employs the retraction method to compute and evaluate the margin from CTV to PTV based on the influence of target dosimetry of setup errors during cervical carcinoma patients treatment. Methods: Sixteen patients with cervical cancer were treated by Elekta synergy and received a total of 305 KV-CBCT images. The iso-center of the initial plans were changed according to the setup errors to simulate radiotherapy and then recalculated the dose distribution using leaf sequences and MUs for individual plans. The margin from CTV to PTV will be concluded both by the method of retracting (Fixed the PTV of the original plan, and retract PTV a certain distance defined as simulative organization CTVnx. The minimum distance value from PTV to CTVnx which get specified doses, namely guarantee at least 99% CTV volume can receive the dose of 95%, is the margin CTV to PTV we found) and the former formula method. Results: (1)The setup errors of 16 patients in X, Y and Z directions were(1.13±2.94) mm,(−1.63±7.13) mm,(−0.65±2.25) mm. (2) The distance between CTVx and PTV was 5, 9 and 3mm in X, Y and Z directions According to 2.5+0.7σ. (3) Transplantation plans displayed 99% of CTVx10- CTVx7 and received 95% of prescription dose, but CTVx6- CTVx3 departed from standard of clinic.In order to protect normal tissues, we selected 7mm as the minimum value of the margin from CTV to PTV. Conclusion: We have test an retraction method for the margin from CTV to PTV evaluation. The retraction method is more reliable than the formula method for calculating the margin from the CTV to the PTV, because it represented practice of treatment, and increasing a new method in this field.

    To study MRI and positron emission tomography (PET)/CT imaging of osteoradionecrosis (ORN) of the subaxial cervical spine, a serious long-term complication of radiation therapy (RT) for head and neck cancers that can lead to pain, vertebral instability, myelopathy and cord compression. This is a single-institution retrospective review of patients diagnosed and treated for ORN of the subaxial cervical spine following surgery and radiation for head and neck cancer. We report PET/CT imaging and MRI for four patients, each with extensive treatment for recurrent head and neck cancer. Osteomyelitis (OM) and discitis are the end-stage manifestations of ORN of the subaxial spine. ORN of the subaxial spine has variable imaging appearance and needs to be differentiated from recurrent or metastatic disease. Surgical violation of the posterior pharyngeal wall on top of the compromised vasculature in patients treated heavily with RT may pre-dispose the subaxial cervical vertebrae to ORN, with possible resultant OM and discitis. MRI and PET/CT imaging are complimentary in this setting. PET/CT images may be misinterpreted in view of the history of head and neck cancer. MRI should be utilized for definitive diagnosis of OM and discitis in view of its imaging specificity. We identify the end-stage manifestation of ORN in the sub-axial spine on PET/CT and MRI to facilitate its correct diagnosis.

    Metal oxide nanoparticles have been widely investigated for its use in the pharmacological field. The present study was aimed to investigate the cytotoxicity of copper oxide nanorods in human cervical carcinoma cells. The effect of copper oxide nanorods on cell viability was determined by sulforhodamine-B (SRB) assay. The fluorescence and confocal microscopy analyzes showed the cell rounding and nuclear fragmentation following exposure of copper oxide nanorods. Reactive oxygen species (ROS) was increased and could initiate membrane lipid peroxidation, which in turn regulate cytokinetic movements of cells. The messenger RNA (mRNA) expression of p53 and caspase 3 was increased, which further confirms the occurrence of apoptosis at the transcriptional level. Furthermore, caspase-3 enzyme activity was increased, which also confirms the occurrence of apoptosis in tumor cells at the translational level. Taking all our experimental results together, it may suggest that the copper oxide nanorods could be a potential anti-tumor agent to inhibit cancer cell proliferation.

    Molecular genetic studies on HeLa cell-derived nontumorigenic and tumorigenic hybrids have previously localized the HeLa cell tumor-suppressor gene to the long arm of chromosome 11. Extensive molecular and cytogenetic studies on HeLa cells have shown chromosome band 11q13 to be rearranged in this cell line. To determine whether q13 rearrangement is a nonrandom event in cervical carcinomas, six different human papilloma virus (HPV)-positive (HeLa, SiHa, Caski, C4-I, Me180, and Ms751) and two different HPV-negative (C33A and HT3) cell lines were studied. Long-range restriction mapping using a number of q13-specific probes showed molecular arrangements within 75 kb of INT2 probe in three HPV-positive cell lines (HeLa, SiHa, and Caski) and in an HPV-negative cell line (HT3). FISH using an INT2 YAC identified a breakpoint within the sequences spanned by this YAC in two of the cell lines, HeLa and Caski. INT2 cosmid derived from this YAC showed deletion of cosmid sequences in two other cell lines, SiHa and C33A. These two cell lines, however, retained cosmid sequences of Cyclin D1, a probe localized 100 kb proximal to INT2. Deletions being the hallmark of a tumor-suppressor gene, we conclude that the 100-kb interval between the two cosmids might contain sequences of the cervical carcinoma tumor-suppressor gene. 28 refs., 9 figs.

    Purpose : Hysterectomy without lymph node dissection was considered an inadequate treatment method for invasive uterine cervix cancer. Usually the procedure was performed inadvertently on patients who were thought to have benign or premalignant conditions preoperatively. We analysed radiotherapy results of such patients to evaluate survival rates, failure patterns and prognostic factors according to various conditions. Methods and Materials : Sixty one patients undergoing hysterectomy in the presence of invasive cervical carcinoma were reviewed retrospectively. Preoperative diagnosis were carcioma in situ (38 cases), severe dysplasia(2), myoma(6), uterine bleeding (4), uterine prolapse (2), and early invasive cervix cancer (10) (One patient had myoma and carcinoma in situ coincidently). Patients received postoperative megavoltage radiotherapy form August 1985 to December 1993, and minimum follow-up period was 24 months. Eight patients reveived ICR only, 6 patients ICR and external radiation, and 47 patients received external radiation therapy only. Results : Overall 5-year survival rate and relapse-free survival rate were 83.8%, 86.9% respectively. For patients with retrospective stage IA, IB, IIB (gross residual after surgery), and vaginal cuff recurrence were 90.9%, 88.8%, 38.4%, and 100% respectively. There were 8 cases of treatment failure, most of them (5/8) were in patients with gross residual disease, other patients were full thickness involvement of cervix wall (2/8) except one. Patients with early vaginal cuff recurrence and microinvasive cervical cncer (stage IA) had no treatment related failure. Prognostic factors affecting survival by univariate analysis were status of residual disease, tumor histology and retrospective stage. Conclusion : Adjuvant radiotherapy appeared to be effective treatment method for patients with presumed stage IA, IB and early local recurrent disease after inadvertent hysterectomy. Survivals for patients with gross disease

    Full Text Available Due to the highly glycolytic metabolism of solid tumours, there is an increased acid production, however, cells are able to maintain physiological pH through plasma membrane efflux of the accumulating protons. Acid efflux through MCTs (monocarboxylate transporters constitutes one of the most important mechanisms involved in tumour intracellular pH maintenance. Still, the molecular mechanisms underlying the regulation of these proteins are not fully understood. We aimed to evaluate the association between CD147 (MCT1 and MCT4 chaperone and MCT expression in cervical cancer lesions and the clinico-pathological significance of CD147 expression, alone and in combination with MCTs. The series included 83 biopsy samples of precursor lesions and surgical specimens of 126 invasive carcinomas. Analysis of CD147 expression was performed by immunohistochemistry. CD147 expression was higher in squamous and adenocarcinoma tissues than in the non-neoplastic counterparts and, importantly, both MCT1 and MCT4 were more frequently expressed in CD147 positive cases. Additionally, co-expression of CD147 with MCT1 was associated with lymph-node and/or distant metastases in adenocarcinomas. Our results show a close association between CD147 and MCT1 and MCT4 expressions in human cervical cancer and provided evidence for a prognostic value of CD147 and MCT1 co-expression.

    Purpose: To document the MRI appearances of radiation-induced abnormalities in the cervical spine following treatment for nasopharyngeal carcinoma (NPC). Methods: Patients with radiation-induced abnormalities in the upper cervical spine were identified from a retrospective analysis of reports from patients undergoing MRI follow-up. Imaging and clinical records of these patients were reviewed. Symmetrical distribution of abnormalities at C1 (anterior arch {+-} adjacent aspect of the lateral masses) and C2 (dens {+-} body especially with a characteristic horizontal rim of marrow preservation above the inferior endplate) were considered typical for osteoradionecrosis (ORN). Results: Abnormalities of C1/2 were identified in 9/884 (1%) patients. The MRI distribution of abnormalities was typical for ORN in four and atypical in five patients. Abnormal soft tissue was present in the atlantoaxial joint in eight patients, forming a florid mass in six. This soft tissue was in direct continuity with the posterior nasopharyngeal wall ulceration via the retropharyngeal region. The final clinical diagnosis was ORN in eight, five of whom had clinical factors which suggested infection could have played a contributory role, and osteomyelitis in one patient. All patients had undergone additional radiotherapy treatment comprising of brachytherapy (7), stereotactic radiotherapy (1) or radiotherapy boost (2) and three had undergone nasopharyngectomy. Conclusion: ORN of the upper cervical spine following radiotherapy for NPC is more common than previously suspected and is seen in patients with additional treatment, especially brachytherapy. MRI features are often atypical and a contributory role of infection in the development of some cases of ORN is postulated.

The authors performed a retrospective chart review among women who were treated for cytological low-grade squamous intraepithelial lesion (LSIL) or high-grade squamous intraepithelial lesion (HSIL) from January 2009 until December 2010. All patients who were treated for deviant Pap-smears were analyzed. Patient characteristics were taken into account when performing the analysis. Data were analyzed using SPSS. Logistic regression was performed to determine the influence of age, smoking, and the reason to perform the Pap-smear. A total of 723 patients with deviant Pap-smear results were analysed. High-grade cervical intraepithelial neoplasia (CIN) was found in 70.3% of the patients with a Pap 3A average dysplasia (low-grade squamous intraepithelial lesion). This indicates that 29.7% of the patients would be over-treated with a 'see and treat' approach. For Pap 3B (high-grade intra-epithelial lesion) or higher the over-treatment percentage was 6.7% or less. Potential risks of a loop electrosurgical excision procedure (LEEP) on future pregnancies and fertility should be taken into account when treating fertile patients for potential CIN. This should be part of the counseling process of patients with a Pap 3A average dysplasia. A 'see and treat' approach can and probably should be proposed to patients with a Pap 3B or higher.

    Full Text Available Background and Purpose: Conventional portals, based on bony anatomy, for external beam radiotherapy for cervical cancer have been repeatedly demonstrated as inadequate. Conversely, with image-based conformal radiotherapy, better target coverage may be offset by the greater toxicities and poorer compliance associated with treating larger volumes. This study was meant to dosimetrically compare conformal and conventional radiotherapy. Materials and Methods: Five patients of carcinoma cervix underwent planning CT scan with IV contrast and targets, and organs at risk (OAR were contoured. Two sets of plans-conventional and conformal were generated for each patient. Field sizes were recorded, and dose volume histograms of both sets of plans were generated and compared on the basis of target coverage and OAR sparing. Results: Target coverage was significantly improved with conformal plans though field sizes required were significantly larger. On the other hand, dose homogeneity was not significantly improved. Doses to the OARs (rectum, urinary bladder, and small bowel were not significantly different across the 2 arms. Conclusion: Three-dimensional conformal radiotherapy gives significantly better target coverage, which may translate into better local control and survival. On the other hand, it also requires significantly larger field sizes though doses to the OARs are not significantly increased.

    Retrospective study based on a reference paper. Neurological outcome in patients who were managed surgically with closed traumatic cervical spine injury was evaluated using the ASIA motor scoring system and Frankel grading. To assess the accuracy of motor charting and Frankel grading as tools to evaluate neurological outcome in closed traumatic cervical spine injury, and also to evaluate how the surgically treated patients fared in their neurological recovery by measurement tools as in the reference paper. National Spinal Injuries Centre, Stoke Mandeville Hospital, Aylesbury, UK. Fifty-seven patients were admitted within 2 days of the injury with closed traumatic cervical spine injuries (1997-2004). Thirty-seven (65%) met the inclusion criteria as per the referenced paper, that is, were treated surgically, were Frankel grade B and above and had at least 12 months follow up. The remaining 20 patients were not included as they did not meet the inclusion criteria. The breakdown of the 20 patients is given in Table 1. The mean recovery percentage (MRP) and mean deficit percentage (MDP) were calculated as per the referenced paper. An evaluation of 37 patients surgically treated, who had follow up of at least 12 months, showed that preservation of pin prick below the level of lesion, and preservation of anal tone and perianal sensation were good prognostic indicators. There was no correlation between degree of encroachment of canal or the degree of kyphosis to MDP or MRP. The mean time from injury to mobilization was 7.6 days in 25 out of 37 patients. Twelve of the 37 patients had prolonged immobilization because of ITU stay or because they were initially treated conservatively. Three out of the 37 patients developed DVT/PE. Mean hospital stay was 6.4 months. The neurological outcome in surgically treated patients is comparable to the conservatively treated patients. The Frankel grading and ASIA motor charting combined is a powerful tool in assessing the neurological

    Objective: To treat injury of the lower cervical spine C6 to C7 with cervical lateral mass plates and T1 pedicle screws through posterior approach. Methods: The data of 8 patients with lower cervical spine C6 or C7 injury (6 patients with fracture and dislocation in C6 and C7 and 2 with fracture in C7) were analyzed retrospectively in this study. For the preoperative American Spinal Injury Association (ASIA) classification, Grade C was found in 3 cases and Grade D in 5 cases. Screws were placed on the lateral masses and the first thoracic pedicle with Margerl technique. Lamina or facet bone allografting was used to achieve a long-term stability. Results: All the 8 patients were followed up for 5-37 months (mean: 15 months). No operative death occurred. There were no examples of aggravation of spinal cord injury or vertebral artery injury, cerebrospinal fluid leak, nerve roots injury, screw malposition or back-out, loose of alignment or implant failure. Clinical symptoms and ASIA classification were improved in all the patients. Postoperative MRI scanning confirmed the satisfactory screw placement in all the cases. Conclusions: Lateral mass plates and pedicle screws through posterior approach are safe and beneficial for patients with lower cervical spine C6 or C7 injury.

    Introduction: Oral Verrucous Carcinoma (OVC) is described apart of the Squamous Cell Carcinoma (SCC) due to its specific properties. The objective of our study is to show our series of cases of OVC and to compare with the SCC in terms of clinical manifestations, epidemiology, histopathology, treatment and follow-up. Material and Methods: This is a retrospective study of all the OVC treated in our department between January-2007 and December-2011. The analyzed variables were sex, age, localization in the oral cavity, histopathology, number of biopsies needed to diagnose OVC, TNM classification, treatment and recurrences during follow-up. Results: Our sample was composed by n=14 patients, 57% female, with a mean age of 69.14 years. The most common localization was buccal mucosa (n=5). Seven patients were diagnosed of OVC with the first biopsy. TNM classification was: pT1: 7 patients, pT2: 3 patients, pT3: 3 patients, pT4: 1 patient. No cervical metastases were observed either in cervical neck dissection or during the follow-up of the patients. The treatment was surgery with clinical resection margins up to 1 cm in all cases, followed by radiotherapy in selected cases. Only n=1 patient (7.69%) presented a recurrence after 34 months of follow-up. The overall survival rate was 92.85%. Conclusions: In our population, OVC represents the 6.16% of all oral cavity and oropharynx cancer, and is more frequent in female patients above 70 years old. It uses to rise over a previous lesion, and usually affects the buccal mucosa. In patients with high suspicious lesions, more than one biopsy may be needed to diagnose OVC. No patient showed cervical dissemination. In our experience, treatment based on local resection, without cervical neck dissection, could be a good option for these patients. Key words:Verrucous carcinoma, squamous cell carcinoma, oral cancer, oral cavity, epidemiology, follow-up. PMID:24880446

    High risk human papillomavirus (HR HPV) infects cells at the squamocolumnar junction (SCJ) of the cervix, causing cancer. Cytokeratin (CK)7 is an SCJ marker, and stains cervical neoplasia. CK19 is a binding partner of CK7 and expressed in cervical cancer. Despite this possible association between CK7/CK19 and cervical cancer, not much is known about the mechanism of CK7/CK19 involvement in HR HPV-mediated cervical carcinogenesis. We analyzed the expression pattern of CK7, CK19, and p16 by using immunohistochemistry and HPV infection by in situ hybridization in 25 cases of high grade cervical intraepithelial neoplasia (CIN3) and in 30 cases of squamous cell carcinoma (SCC). CK19, p16, and HPV expression was positive in all CIN3 and SCC cases. CK7 expression was positive in all CIN3 cases and in 20/30 (66%) SCCs. Each protein showed diffuse or patchy staining with topographic distinction. Patchy staining of CK7 and episomal HPV DNA overlapped in the upper layer of CIN3 and central portion of an invasive nest in the SCC, whereas patchy CK19 staining and integrated HPV DNA were usually noted in the lower layer of CIN3 and the periphery of the SCC nest. The p16 staining pattern coincided with that of CK19 in a subset of SCC. These results suggest that CK7 may be more related with viral episomal replication and CK19 with viral integration, contributing to viral replication and malignant transformation in HR HPV infected cells. In addition, coordinate CK7/CK19 staining may be used as a valuable marker for predicting physical status of HR HPV and E7 oncoprotein level in cervical tumor.

    The time course of human papillomavirus (HPV) DNA clearance was studied in patients with carcinoma of the cervix during follow-up after primary radical radiotherapy (RT). This study investigated the relationship between timing of HPV clearance and RT effectiveness. A total of 71 consecutive patients who were treated for cervical cancer with primary radical radiotherapy and high-dose rate intracavitary brachytherapy with or without chemotherapy were enrolled in the study. Samples for HPV DNA examination were taken before (1) treatment, (2) every brachytherapy, and (3) every follow-up examination. The times when HPV DNA was undetected were analyzed for association with recurrence-free survival. HPV DNA was not detected in 13 patients (18 %) before RT. Of the 58 patients with HPV DNA detected before treatment, HPV DNA was not detected in 34 % during treatment and in 66 % after the treatment. Within 6 months after RT, HPV DNA was detected in 0 % of all patients. The patients were followed up for a median period of 43 months (range 7-70 months). In all, 20 patients were found to develop recurrence. The 3-year cumulative disease-free survival (DFS) rate was 71 ± 5.4 % for all 71 patients. In multivariate analysis, DFS was significantly associated with HPV (detected vs. not detected) with a hazard ratio of 0.07 (95 % confidence interval 0.008-0.6, p = 0.009). In this study, patients in whom HPV was not detected had the worst prognosis. Six months after RT, HPV DNA was detected in 0 % of the patients. Patients in whom HPV DNA could not be detected before treatment need careful follow-up for recurrence and may be considered for additional, or alternative treatment. (orig.)

    Carcinoma in the external auditory canal (EAC) is a rare malignancy with an annual incidence of one per one million people, accounting for less than 0.2% of all head and neck cancers. The most common histopathological type of EAC cancer is squamous cell carcinoma. Verrucous carcinoma is a well-differentiated, low-grade variant of squamous cell carcinoma. It is a locally destructive, invasive, and slow growing tumor that rarely metastasizes. Verrucous carcinoma occurs predominantly in the oral cavity and larynx, and its occurrence in the EAC is extremely rare. In this report, we present a histologically confirmed case of verrucous carcinoma in the EAC and temporal bone, which for several years had been classified as epithelial hyperplasia. Two-and-a-half years after diagnosis of verrucous carcinoma, a recurrent mass was found and the lesion was then confirmed to be squamous cell carcinoma.

    Normal human foreskin keratinocytes cotransfected with the neomycin resistance gene and recombinant human papillomavirus (HPV) DNAs (types 16, 18, 31, and 33) that have a high or moderate association with cervical malignancy acquired immortality and contained integrated and transcriptionally active viral genomes. Only transcripts from the intact E6 and E7 genes were detected in at least one cell line, suggesting that one or both of these genes are responsible for immortalization. Recombinant HPV DNAs with low or no oncogenic potential for cervical cancer (HPV1a, -5, -6b, and -11) induced small G418-resistant colonies that senesced as did the nontransfected cells. These colonies contained only episomal virus DNA; therefore, integration of HPV sequences is important for immortalization of keratinocytes. This study suggests that the virus-encoded immortalization function contributes to the pathogenesis of cervical carcinoma.

    Purpose: To compare two registration methods in the CBCT guided radiotherapy for cervical carcinoma, analyze the setup errors and registration methods, determine the margin required for clinical target volume(CTV) extending to planning target volume(PTV). Methods: Twenty patients with cervical carcinoma were enrolled. All patients were underwent CT simulation in the supine position. Transfering the CT images to the treatment planning system and defining the CTV, PTV and the organs at risk (OAR), then transmit them to the XVI workshop. CBCT scans were performed before radiotherapy and registered to planning CT images according to bone and gray value registration methods. Compared two methods and obtain left-right(X), superior-inferior(Y), anterior-posterior (Z) setup errors, the margin required for CTV to PTV were calculated. Results: Setup errors were unavoidable in postoperative cervical carcinoma irradiation. The setup errors measured by method of bone (systemic ± random) on X(1eft.right),Y(superior.inferior),Z(anterior.posterior) directions were(0.24±3.62),(0.77±5.05) and (0.13±3.89)mm, respectively, the setup errors measured by method of grey (systemic ± random) on X(1eft-right), Y(superior-inferior), Z(anterior-posterior) directions were(0.31±3.93), (0.85±5.16) and (0.21±4.12)mm, respectively.The spatial distributions of setup error was maximum in Y direction. The margins were 4 mm in X axis, 6 mm in Y axis, 4 mm in Z axis respectively.These two registration methods were similar and highly recommended. Conclusion: Both bone and grey registration methods could offer an accurate setup error. The influence of setup errors of a PTV margin would be suggested by 4mm, 4mm and 6mm on X, Y and Z directions for postoperative radiotherapy for cervical carcinoma.

    Highlights: • Gold nanoparticles (AuNPs) have been synthesized using Podophyllum hexandrum L. • AuNPs induces the oxidative stress to cell death in human cervical carcinoma cells. • It activates the caspase-cascade to cellular death. • It is actively blocks G2/M phase of cell cycle. - Abstract: Current prospect of nanobiotechnology involves in the greener synthesis of nanostructured materials particularly noble metal nanoparticles for various biomedical applications. In this study, biologically (Podophyllum hexandrum L.) synthesized crystalline gold nanoparticles (AuNPs) with the size range between 5 and 35 nm were screened for its anticancereous potential against human cervical carcinoma cells (HeLa). Stoichiometric proportion of the reaction mixture and conditions were optimized to attain stable nanoparticles with narrow size range. Different high throughput techniques like transmission electron microscope (TEM), X-ray diffraction (XRD) and UV–vis spectroscopy were adopted for the physio-chemical characterization of AuNPs. Additionally, Fourier transform infrared spectroscopy (FTIR) study revealed that the water soluble fractions present in the plant extract solely influences the reduction of AuNPs. Sublimely, synthesized AuNPs exhibits an effective in vitro anticancer activity against HeLa cells via induction of cell cycle arrest and DNA damage. Furthermore, it was evidenced that AuNPs treated cells are undergone apoptosis through the activation of caspase cascade which subsequently leads to mitochondrial dysfunction. Thereby, this study proves that biogenic colloidal AuNPs can be developed as a promising drug candidature for human cervical cancer therapy.

    Full Text Available The p53 target gene WIG-1 (ZMAT3 is located in chromosomal region 3q26, that is frequently amplified in human tumors, including cervical cancer. We have examined the status of WIG-1 and the encoded Wig-1 protein in cervical carcinoma cell lines and tumor tissue samples. Our analysis of eight cervical cancer lines (Ca Ski, ME-180, MS751, SiHa, SW756, C-4I, C-33A, and HT-3 by spectral karyotype, comparative genomic hybridization and Southern blotting revealed WIG-1 is not the primary target for chromosome 3 gains. However, WIG-1/Wig-1 were readily expressed and WIG-1 mRNA expression was higher in the two HPV-negative cervical cell lines (C33-A, HT-3 than in HPV-positive lines. We then assessed Wig-1 expression by immunohistochemistry in 38 cervical tumor samples. We found higher nuclear Wig-1 expression levels in HPV-negative compared to HPV positive cases (p = 0.002 and in adenocarcinomas as compared to squamous cell lesions (p<0.0001. Cases with moderate nuclear Wig-1 staining and positive cytoplasmic Wig-1 staining showed longer survival than patients with strong nuclear and negative cytoplasmic staining (p = 0.042. Nuclear Wig-1 expression levels were positively associated with age at diagnosis (p = 0.023 and histologic grade (p = 0.034. These results are consistent with a growth-promoting and/or anti-cell death function of nuclear Wig-1 and suggest that Wig-1 expression can serve as a prognostic marker in cervical carcinoma.

    OBJECTIVE To investigate the influence of positive lymph nodes on the prognosis for patients with stage Ib-IIb cervical carcinoma.METHODS Sixty-six patients with stage Ib-IIb cervical carcinoma who underwent a radical hysterectomy and pelvic lymphadenectomy were analyzed retrospectively. The potential prognostic factors were calculated by the Cox proportional hazard model.RFSULTS The 5-year survival of metastasis was 40.7%. The Coxthe patients with pelvic lymph node proportional hazard model analysis showed that cellular differentiation, the number of positive nodes and adjuvant therapy were independent prognostic factors (PO.05). The 5-year survival of the patients who had no adjuvant therapy (12.6%) was much lower than that(53.7%) of those with adjuvant therapy (P0.05).CONCLUSION The prognosis of patients with stage Ib-IIb node-positive cervical carcinoma who underwent radical surgery was poor. Adjuvant therapy can increase the survival rate, decrease the pelvic recurrence and distant metastasis.

    High-risk human papillomaviruses (HPVs), including HPV-16 and HPV-18, are the causative agents of cervical carcinomas and are linked to several other tumors of the anogenital and oropharyngeal regions. The majority of HPV-induced tumors contain integrated copies of the normally episomal HPV genome that invariably retain intact forms of the two HPV oncogenes E6 and E7. E6 induces degradation of the cellular tumor suppressor p53, while E7 destabilizes the retinoblastoma (Rb) protein. Previous work has shown that loss of E6 function in cervical cancer cells induces p53 expression as well as downstream effectors that induce apoptosis and cell cycle arrest. Similarly, loss of E7 allows increased Rb expression, leading to cell cycle arrest and senescence. Here, we demonstrate that expression of a bacterial Cas9 RNA-guided endonuclease, together with single guide RNAs (sgRNAs) specific for E6 or E7, is able to induce cleavage of the HPV genome, resulting in the introduction of inactivating deletion and insertion mutations into the E6 or E7 gene. This results in the induction of p53 or Rb, leading to cell cycle arrest and eventual cell death. Both HPV-16- and HPV-18-transformed cells were found to be responsive to targeted HPV genome-specific DNA cleavage. These data provide a proof of principle for the idea that vector-delivered Cas9/sgRNA combinations could represent effective treatment modalities for HPV-induced cancers. Importance: Human papillomaviruses (HPVs) are the causative agents of almost all cervical carcinomas and many other tumors, including many head and neck cancers. In these cancer cells, the HPV DNA genome is integrated into the cellular genome, where it expresses high levels of two viral oncogenes, called E6 and E7, that are required for cancer cell growth and viability. Here, we demonstrate that the recently described bacterial CRISPR/Cas RNA-guided endonuclease can be reprogrammed to target and destroy the E6 or E7 gene in cervical carcinoma cells

    Full Text Available Abstract Background Cervical cancer is treated mainly by surgery and radiotherapy. Toxicity due to radiation is a limiting factor for treatment success. Determination of lymphocyte radiosensitivity by radio-induced apoptosis arises as a possible method for predictive test development. The aim of this study was to analyze radio-induced apoptosis of peripheral blood lymphocytes. Methods Ninety four consecutive patients suffering from cervical carcinoma, diagnosed and treated in our institution, and four healthy controls were included in the study. Toxicity was evaluated using the Lent-Soma scale. Peripheral blood lymphocytes were isolated and irradiated at 0, 1, 2 and 8 Gy during 24, 48 and 72 hours. Apoptosis was measured by flow cytometry using annexin V/propidium iodide to determine early and late apoptosis. Lymphocytes were marked with CD45 APC-conjugated monoclonal antibody. Results Radiation-induced apoptosis (RIA increased with radiation dose and time of incubation. Data strongly fitted to a semi logarithmic model as follows: RIA = βln(Gy + α. This mathematical model was defined by two constants: α, is the origin of the curve in the Y axis and determines the percentage of spontaneous cell death and β, is the slope of the curve and determines the percentage of cell death induced at a determined radiation dose (β = ΔRIA/Δln(Gy. Higher β values (increased rate of RIA at given radiation doses were observed in patients with low sexual toxicity (Exp(B = 0.83, C.I. 95% (0.73-0.95, p = 0.007; Exp(B = 0.88, C.I. 95% (0.82-0.94, p = 0.001; Exp(B = 0.93, C.I. 95% (0.88-0.99, p = 0.026 for 24, 48 and 72 hours respectively.

    Annexin 1 (ANXA1) is a substrate for E6AP mediated ubiquitylation. It has been hypothesized that HPV 16 E6 protein redirects E6AP away from ANXA1, increasing its stability and possibly contributing to viral pathogenesis. We analyzed ANXA1 expression in HPV-positive and negative cervical carcinoma-derived cells, in cells expressing HPV-16 oncogenes and in cells transduced with shRNA targeting E6AP. We observed that ANXA1 protein expression increased in HPV-16-positive tumor cells, in keratinocytes expressing HPV-16 E6wt (wild-type) or E6/E7 and C33 cells expressing HPV-16 E6wt. ANXA1 protein expression decreased in cells transfected with E6 Dicer-substrate RNAs (DsiRNA) and C33 cells cotransduced with HPV-16 E6wt and E6AP shRNA. Moreover, colony number and proliferation rate decreased in HPV16-positive cells transduced with ANXA1 shRNA. We observed that in cells infected with HPV16, the E6 binds to E6AP to degrade p53 and upregulate ANXA1. We suggest that ANXA1 may play a role in HPV-mediated carcinogenesis. - Highlights: • ANXA1 upregulation requires the presence of E6 and E6AP and is dependent on E6 integrity. • E6 binds to E6AP to degrade p53 and upregulate ANXA1 in cells infected with HPV16. • ANXA1 plays a role in cell proliferation in HPV-positive cervical cells.

    In the treatment of papillary thyroid carcinoma (PTC), supplementary lymph node dissection (LND) is not well standardized. The purpose of this study was to evaluate the significance of the cervical compartments in the lymphatic spread of PTC and the impact of modified radical neck dissection (MRND) as an additional surgical procedure to thyroid resection. From 1999 to 2002, LND of the central compartment (compartment A) was performed in 39 patients. Among this group, additional MRND of the ipsilateral compartment (compartment B) and the contralateral compartment (compartment C) was performed in 29 and 15 patients respectively, who met the selection criteria. The mean number of nodes resected was 11 (5-22) in compartment A, 23 (8-37) in compartment B, and 22 (10-31) in compartment C. Histopathologic findings revealed node invasion of compartment A in 25 patients (64.1%), of A and B in 20 patients (51,2%) and of A, B, and C in 13 patients (33.3%). From the 25 patients with metastases in compartment A, 80% (20 patients) already had metastases in compartment B and 52% (13 patients) had metastases in all three compartments. All patients free of metastasis (M0) in compartment A were also metastasis free in both lateral compartments. Postoperative whole-body scanning I(131) in M0 patients showed no uptake at all. Mapping of the cervical anatomy in compartments seems to be a useful taxonomy for clarifying the lymphatic spread of PTC. Patients having PTC without metastasis in compartment A are almost certainly disease free at the time of operation. Lymph node metastasis in the central compartment appears to be a valuable indicator of lymphatic invasion of the lateral compartment and a strong indication for performance of a unilateral or bilateral MRND to complete the surgical removal of tumor.

    Invasive squamous cell carcinoma (SCC) of the cervix involves the progression of premalignant cervical intraepithelial neoplasia (CIN) and is associated with persistent human papillomavirus infection. Most CINs will regress, and the challenge is to identify the lesions likely to progress to invasive cancer. We evaluated Sirtuin 1 (SIRT1) expression in nonneoplastic cervix, CINs, and SCCs as a potential biomarker to predict disease progression. A total of 101 cases were selected including 29 CIN 1s, 32 CIN 2s, 16 CIN 3s, 2 microinvasive SCCs, and 22 invasive SCCs. Cervical nonneoplastic squamous epithelium showed weak positivity of SIRT1 in the basal layer. SIRT1 cytoplasmic overexpression was found in 13.8% of CIN 1s (4/29), 40.6% of CIN 2s (13/32), and 50% of CIN 3s (8/16), and it was statistically significant between CIN 1 and CIN 2/3 lesions (P=.01). All 24 cases of invasive and microinvasive SCC showed SIRT1 overexpression, with 25% (6/24) showing cytoplasmic staining only, 4.2% (1/24) showing nuclear staining only, and 70.8% (17/24) showing both nuclear and cytoplasmic staining. From CIN 1 to SCC, SIRT1 expression showed steady and statistically significant increase (CIN 1 versus CIN 2-3, P=.01; CIN 2-3 versus SCC, P=.0001). Thus, SIRT1 may serve as a potential biomarker for predicting the progression of CIN to invasive SCC. Copyright © 2016 Elsevier Inc. All rights reserved.

    The aim of this study was to investigate the role of HPV 18 E6 and E7 gene products with respect to radiosensitivity of two cervical carcinoma cell lines. The two cervical carcinoma lines C4-1 and SW 756 were used in which treatment with dexamethasone allows to modulate expression levels of HPV 18 E6 and E7 genes: Upregulation in C4-1, down-regulation in SW 756. Effects of treatment with dexamethasone on plating efficiency and radiosensitivity were assessed using a clonogenic assay. Treatment with dexamethasone increased plating efficiency of the C4-1 cells, but did not affect plating efficiency of SW 756 cells. Treatment with dexamethasone induced enhanced radioresistance in both cell lines. Thus, in C4-1 cells the observed changes in radioresistance correlate to the enhancement in expression of HPV 18 genes E6/E7, whereas in SW 756, a reduced expression correlates negatively with the enhanced radioresistance. (orig./MG) [Deutsch] Das Ziel dieser Studie lag darin, die Rolle der HPV-18-Gene E6 und E7 in bezug auf die Strahlenempfindlichkeit von menschlichen Zervixkarzinomzellen zu untersuchen. Wir verwendeten zwei menschliche Zervixkarzinomzellinien, C4-1 und SW 756, in welchen die Expression der viralen Gene HPV 18 E6 und E7 mit Dexamethason moduliert werden kann: In C4-1 bewirkt die Behandlung mit Dexamethason eine Erhoehung der Expression dieser Gene, in SW 756 eine Verminderung. Die Wirkung auf die Wachstumsfaehigkeit der Zellen und auf die Wachstumshemmung durch die Bestrahlung wurde unter Verwendung eines klonogenen Assays bestimmt. Dexamethason bewirkte eine erhoehte Wachstumsfaehigkeit der C4-1 Zellen, ohne die Wachstumsfaehigkeit der SW-756-Zellen zu beeinflussen, wie schon frueher beschrieben. Die Resistenz beider Zellinien gegenueber Bestrahlung wurde erhoeht. Somit besteht in den C4-1-Zellen eine Korrelation der Expression der viralen Gene mit der Zunahme der Strahlenresistenz, wogegen in den SW-756-Zellen die Abnahme der Expression im Gegensatz zu

    Full Text Available Introduction. Thyroglobulin is composed glycoprotein, and it is synthesized by follicular cells of the thyroid gland. Treatment of differentiated thyroid carcinomas involves total thyroidectomy followed by radioiodine ablation of a potential remaining tissue. The measurement of thyroglobulin in the postoperative follow-up can serve as an indicator of tumor growth or recurrence of the disease. Objective. The aim of this paper is to examine the value of thyroglobulin in patients surgically treated for differentiated thyroid cancer who had metastases in the lymph nodes of the neck, as well as in operated on patients without any evident metastasis. Methods. Thyroglobulin values in the serum of 58 patients were analyzed. Two groups were formed. The thyroglobulin value was established with the use of IRMA-hTg (125I system. Normal levels of thyroglobulin were from 2 ng/ml to 65 ng/ml. For all of 58 patients, thyroglobulin was determined three times. The first, so-called pre-ablation thyroglobulin was determined immediately before the application of 131I ablation dose. The second and the third measurements were conducted six to eight months and one year, respectively, after the application of the ablation dose respectively. Results. The first group consisted of 14 patients with histologically proven metastases in the lymph nodes of the neck, while the second group consisted of 44 patients without any evident metastases. The average thyroglobulin value of pre-ablation in the patients from the first group was 43.45 ng/ml, while in the second was 7.57 ng/ml. Levene’s test (with p = 0.00, i.e p < 0.05, demonstrated a statistically significant difference. Furthermore, in both groups, there was statistically significant difference between pre-ablation and post-ablation thyroglobulin values (Student’s t-test with p < 0.05. Conclusion It can be concluded that the average value of thyroglobulin was significantly higher in patients with lymph node metastases

    To investigate the feasibility of contralateral lower neck sparing intensity modulation radiated therapy (IMRT) for nasopharyngeal carcinoma patients (NPC) with unilateral cervical lymph node metastasis. Retrospective review of 546 patients with unilateral cervical lymph node metastasis treated between November 2009 and February 2012 at one institution. All patients were staged using magnetic resonance imaging and received radical IMRT. Patients were classified into two groups: the inferior border of the negative neck irradiation field only covered Levels III to Va in Group 1; the inferior border covered entire neck down to Levels IV to Vb in Group 2. Median follow-up was 49.9months (range, 1.3-69.2months). Four-year overall survival (OS:89.3% vs. 88.9%, P=0.91), disease-free survival (DFS:81.7% vs. 81.0%, P=0.91), distant metastasis-free survival (DMFS:88.2% vs. 87.9%, P=0.95), local relapse-free survival (LRFS:96.7% vs. 94.7%, P=0.70) and nodal relapse-free survival (NRFS: 96.1% vs. 95.9%, P=0.94) were not significantly different between Group 1 and Group 2. Twenty-two patients developed cervical lymph node relapse; of whom 20/22 (91.0%) developed unilateral relapse within pretreatment positive neck. Only one patient developed out-of-field relapse, though this patient also relapsed within the neck irradiation field (Level II). No clinicopathological feature tested had significant prognostic value for NRFS in multivariate analysis. In the IMRT and MRI era, contralateral lower neck sparing IMRT seems to be feasible for NPC patients with unilateral cervical lymph node metastasis. Copyright © 2017. Published by Elsevier Ltd.

    Cervical carcinoma is one of the leading causes of cancer-related death for female worldwide. Eukaryotic initiation factor 5A2 belongs to the eukaryotic initiation factor 5A family and is proposed to be a key factor involved in the development of diverse cancers. In the current study, a series of in vivo and in vitro investigations were performed to characterize the role of eukaryotic initiation factor 5A2 in oncogenesis and metastasis of cervical carcinoma. The expression status of eukaryotic initiation factor 5A2 in 15 cervical carcinoma patients was quantified. Then, the effect of eukaryotic initiation factor 5A2 knockdown on in vivo tumorigenicity ability, cell proliferation, cell cycle distribution, and cell mobility of HeLa cells was measured. To uncover the mechanism driving the function of eukaryotic initiation factor 5A2 in cervical carcinoma, expression of members within RhoA/ROCK pathway was detected, and the results were further verified with an RhoA overexpression modification. The level of eukaryotic initiation factor 5A2 in cervical carcinoma samples was significantly higher than that in paired paratumor tissues (P ROCK I, and ROCK II were downregulated. The above-mentioned changes in eukaryotic initiation factor 5A2 knockdown cells were alleviated by the overexpression of RhoA. The major findings outlined in the current study confirmed the potential of eukaryotic initiation factor 5A2 as a promising prognosis predictor and therapeutic target for cervical carcinoma treatment. Also, our data inferred that eukaryotic initiation factor 5A2 might function in carcinogenesis of cervical carcinoma through an RhoA/ROCK-dependent manner.

    Full Text Available Cervical cancer is the fourth type of women neoplasia, with thousands of new cases annually. It is closely related to human papillomavirus (HPV infection, which has more than 13 oncogenic types, among them HPV 16 and 18 are implicated in 70% of cervical carcinoma cases. Alkaloids are nitrogenated and naturally occurring compounds, showing several uses in medical treatment, including cytotoxic and antineoplastic activities. In this work we aim to evaluate the cytotoxic and chemotherapeutic potential of alkaloids against cervical cancer. In order to accomplish this purpose, we have made a survey of potentially effective alkaloids with cytotoxic activities over HPV-16+ and HPV-18 + cells (HeLa cells. Through a literature review between the years of 1980 and 2015, we described the major alkaloid sources, distribution in nature and also discussed the mechanisms of action for their cytotoxicity. We found that alkaloids showed efficacy as cytotoxic agents, inhibiting cell growth of the HPV-transformed cells in vitro and in vivo by means of activation of intrinsic and extrinsic pathways of apoptosis, which included the clivage of caspases and PARP-1 (Poli-Adenosyl- Ribose Protease 1, increase in p53 expression, release of cytochrome C and increase of cell death receptors expression like Fas, mainly observed in HeLa (HPV- 18 + cell lines. Moreover, these secondary metabolites helped in modulating the MDR (Multi-Drug Resistance against the cell lines studied, which lead us to suggest their possible use as chemotherapeutic agents on the lesions caused by these virusesKeywords: Cervical cancer.

    A 37-year-old male case was admitted with goiter. Ultrasonography of thyroid showed a 5 cm cystic nodule in the left lobe with a 1.5 cm solid component. Fine needle aspiration biopsy revealed atypia of undetermined significance or follicular lesion. The patient was operated on. The pathological diagnosis was reported as papillary thyroid carcinoma. The immunohistochemical examination showed multiple foci of Langerhans cell histiocytosis involving both lobes. The patient died due to cardiac arrest with respiratory causes in the early postoperative period. Langerhans cell histiocytosis is a rare primary condition which involves abnormal clonal proliferation of Langerhans cells in various tissues and organs. Thyroid involvement is infrequently seen. Although the etiology is unknown, genetic components may be linked to the disease. It is also associated with a family history of thyroid disease. Papillary thyroid carcinoma is the most common malignant epithelial tumor of the thyroid gland. Langerhans cell histiocytosis presenting with papillary thyroid carcinoma is rare. The privilege of our case is langerhans cell histiocytosis of the thyroid with multiple cervical lymph node involvement accompanying cervical lymph node metastatic thyroid papillary carcinoma.

    In 129 patients with cervical cancer, CT findings before treatment were analysed on the basis of the outcome during a 5 year follow-up period (75 survivals, and 54 deaths). The incidence of each CT finding in the two groups was as follows. (1) enlargement of the uterine cervix in 40.0% for survivals and 64.8% for deaths; (2) low density area in the cervix in 18.7% and 37.0%; (3) necrotic cavity in 4.0% and 33.3%; (4) pyometra in 8.0% and 31.5%; (5) irregular and indistinct margin of the cervix in 2.7% and 51.9%; (6) abnormal image of parametrium in 25.3% and 87.0%; (7) extension to the vagina in 2.7% and 37.0%; (8) extension toward the bladder in 8.0% and 57.4%; and (9) enlarged lymph node in 0% and 27.8%. CT scores obtained by multivariate analysis for prognostic discrimination of cervical cancer were +1 for (1), -1 for (2), +1 for (3), -3 for (4), +25 for (5), type B +29, C +25, D +10 for (6), +2 for (7), grade I +12, II +7, III +20 for (8), and +18 for (9). The discrimination ratio for the prognosis of cervical cancer was 82.9%. The score obtained by multivariate analysis showed significant increases according with the stage. Even in the same stage, there were significant differences between the scores for survivals and deaths (stage II: p<0.01, stage III: p<0.05). The survival period in the poor prognosis group was correlated with the score, especially when treated with radiotherapy (r=-0.45, p<0.01). (author).

    2011-01-01

    Full Text Available The constitutive proliferation and resistance to differentiation and apoptosis of neoplastic cervical cells depend on sustained expression of human papillomavirus oncogenes. Inhibition of these oncogenes is a goal for the prevention of progression of HPV-induced neoplasias to cervical cancer. SiHa cervical cancer cells were transfected with an HPV-16 promoter reporter construct and treated with leukemia inhibitory factor (LIF, a human cytokine of the interleukin 6 superfamily. SiHa and CaSki cervical cancer cells were also assessed for proliferation by MTT precipitation, programmed cell death by flow cytometry, and HPV E6 and E7 expression by real-time PCR. LIF-treated cervical cancer cells showed significantly reduced HPV LCR activation, reduced levels of E6 and E7 mRNA, and reduced proliferation. We report the novel use of LIF to inhibit viral oncogene expression in cervical cancer cells, with concomitant reduction in proliferation suggesting re-engagement of cell-cycle regulation.

    In order to investigate the analgesic effect of needling at "Sitian" points for the nerve root-involved cervical spondylopathy, 68 cases of the nerve root-involved cervical spondylopathy were randomly divided into a treatment group of 46 cases treated by needling at "Sitian" points, and a control group of 22 cases treated by needling at cervical Jiaji points. After 2 therapeutic courses, the therapeutic effects were evaluated by using the visual analogue scale (VAS) and the semeiographic format. The results showed that the markedly effective rate was 78.3% and 54.5%, respectively in the treatment group and the control group, and the difference between the two groups was of significance (P<0.05). It can be concluded that needling at "Sitian" points can bring about a better therapeutic effect on the improvement of clinical symptoms, physical signs and pain than that of the needling at the cervical Jiaji points.

    Objective: To explore the treatment of clinically negative neck (CN0) patients with squamous cell carcinoma of the tongue. Methods: 165 CN0 patients with squamous cell carcinoma of the tongue from 1985 to 2002 were investigated retrospectively. Parts of the patients staged at T1, T2 and T3 underwent resection of primary lesion followed by neck observation, and other patients staged above T2 or at T1 but without follow-up were treated with elective neck dissection (END). All patients were followed up for more than 3 y or until their death. Results: Lymphatic metastasis was identified histologically after operation in 33 of 120 patients treated with END, and 9 of 45 patients treated with resection of primary lesion alone. The overall rate of occult lymphatic metastasis was 25.45%, which increased with the elevating of clinical T stage. The overall rate of neck uncontrolled death was 20.00% for observation group and 5.00% for END group, and significant difference was found between them (P<0.05). For T1 patients in the two groups, the rate of neck uncontrolled death was 7.71% and 4.00% respectively, and no significance was found between them (P>0.05). When stage T2 and T3 were considered as middle stage together, significant difference (P<0.05) could be obtained between observation (70.00%) and END group (0%). Conclusion: The occult metastasis rate of squamous cell carcinoma of tongue increases with the elevating of clinical stage, and elective neck dissection could be considered for N0 patients staged over T2 to improve neck control and survival rate; and regional resection alone of primary lesion could be considered for T1N0 patients to improve quality of life if closely followed up is conducted.

    Two cases of pyogenic osteomyelitis of pubic bone occurred after irradiation of cervical carcinoma were reported. Case 1: A 69-year-old female received external irradiation of 50 Gy from November 1993 to April 1994 after supravaginal uterine amputation. The left melosalgia and pain at left pubic region appeared from July 1994. On the MRI, bone marrow of the left pubic region showed low brightness by T1 weighted image and equal brightness by T2 weighted image, and the image was enhanced by gadolinium. An abscess in external obturator muscle was suspected. High accumulation was recognized by bone scintigram at the left pubic region. No bacterial infection was recognized. Focus was removed in May 1995. Case 2: A 80-year-old female received external irradiation of 50 Gy and intracavitary irradiation of 30 Gy in May 1992. Pain at left pubic region appeared from June 1993. Dilation of pubic symphysis and osteoclasia of the left pubic bone were detected on the plain radiograph in March 1995. On the MRI, the left pubic bone marrow showed low brightness by T1 weighted image and equal brightness by T2 weighted image, and image was enhanced by gadolinium. An abscess in small pelvic cavity was suspected. Streptococcus agalactae was detected in abscess, and PIPC was administered by drip infusion for five weeks. They are currently alive and doing well about three years later. (K.H.)

    To investigate the potential of various metrics derived from mono-exponential model (MEM), bi-exponential model (BEM) and stretched exponential model (SEM)-based diffusion-weighted imaging (DWI) in diagnosing and differentiating the pathological subtypes and grades of uterine cervical carcinoma. 71 newly diagnosed patients with cervical carcinoma (50 cases of squamous cell carcinoma [SCC] and 21 cases of adenocarcinoma [AC]) and 32 healthy volunteers received DWI with multiple b values. The apparent diffusion coefficient (ADC), pure molecular diffusion (D), pseudo-diffusion coefficient (D*), perfusion fraction (f), water molecular diffusion heterogeneity index (alpha), and distributed diffusion coefficient (DDC) were calculated and compared between tumour and normal cervix, among different pathological subtypes and grades. All of the parameters were significantly lower in cervical carcinoma than normal cervical stroma except alpha. SCC showed lower ADC, D, f and DDC values and higher D* value than AC; D and DDC values of SCC and ADC and D values of AC were lower in the poorly differentiated group than those in the well-moderately differentiated group. Compared with MEM, diffusion parameters from BEM and SEM may offer additional information in cervical carcinoma diagnosis, predicting pathological tumour subtypes and grades, while f and D showed promising significance.

    HPV 16 is the cause of cervical carcinoma, but only a small fraction of women with HPV infection progress to this pathology. Besides persistent infection and HPV integration, several studies have suggested that HPV intratype variants may contribute to the development of cancer. The purpose of this study was to investigate the nucleotide variability and phylogenetically classify HPV 16 E6 variants circulating over a period of 16 years in women from Southern Mexico, and to analyze its association with precursor lesions and cervical carcinoma. This study was conducted in 330 cervical DNA samples with HPV 16 from women who were residents of the State of Guerrero, located in Southern Mexico. According of cytological and/or histological diagnosis, samples were divided into the following four groups: no intraepithelial lesion (n = 97), low-grade squamous intraepithelial lesion (n = 123), high-grade squamous intraepithelial lesion (n = 19) and cervical carcinoma (n = 91). HPV 16 E6 gene was amplified, sequenced and aligned with reference sequence (HPV 16R) and a phylogenetic tree was constructed to identify and classify HPV 16 variants. Chi squared was used and data analysis and statistics were done with SPSS Statistics and STATA softwares. Twenty seven HPV 16 E6 variants were detected in women from Southern Mexico, 82.12% belonged to the EUR, 17.58% to AA1 and 0.3% to Afr2a sublineages. The most common was E-G350 (40%), followed by E-prototype (13.03%), E-C188/G350 (11.82%), AA-a (10.61%), AA-c (6.07%) and E-A176/G350 (5.15%). Eight new E6 variants were found and 2 of them lead to amino acid change: E-C183/G350 (I27T) and E-C306/G350 (K68T). The HPV 16 variant that showed the greatest risk of leading to the development of CC was AA-a (OR = 69.01, CI = 7.57-628.96), followed by E-A176/G350 (OR = 39.82, CI = 4.11-386.04), AA-c (OR = 21.16, CI 2.59-172.56), E-G350 (OR = 13.25, CI = 2.02-87.12) and E-C188/G350 (OR = 10.48, CI

    The aim of this study was to investigate the association of CD147 and GLUT-1, which play important roles in glycolysis in response to radiotherapy and clinical outcomes in patients with locally advanced cervical squamous cell carcinoma (LACSCC). The records of 132 female patients who received primary radiation therapy to treat LACSCC at FIGO stages IB-IVA were retrospectively reviewed. Forty-seven patients with PFS (progression-free survival) of less than 36 months were regarded as radiation-resistant. Eighty-five patients with PFS longer than 36 months were regarded as radiation-sensitive. Using pretreatment paraffin-embedded tissues, we evaluated CD147 and GLUT-1 expression by immunohistochemistry. Overexpression of CD147, GLUT-1, and CD147 and GLUT-1 combined were 44.7%, 52.9% and 36.5%, respectively, in the radiation-sensitive group, and 91.5%, 89.4% and 83.0%, respectively, in the radiation-resistant group. The 5-year progress free survival (PFS) rates in the CD147-low, CD147-high, GLUT-1-low, GLUT-1-high, CD147- and/or GLUT-1-low and CD147- and GLUT-1- dual high expression groups were 66.79%, 87.10%, 52.78%, 85.82%, 55.94%, 82.90% and 50.82%, respectively. CD147 and GLUT-1 co-expression, FIGO stage and tumor diameter were independent poor prognostic factors for patients with LACSCC in multivariate Cox regression analysis. Patients with high expression of CD147 alone, GLUT-1 alone or co-expression of CD147 and GLUT-1 showed greater resistance to radiotherapy and a shorter PFS than those with low expression. In particular, co-expression of CD147 and GLUT-1 can be considered as a negative independent prognostic factor.

    Masaaki Karino

    Full Text Available BACKGROUND: We previously reported the utility of preoperative nuclear morphometry for evaluating risk for cervical lymph node metastases in tongue squamous cell carcinoma. The risk for lymph node metastasis in oral squamous cell carcinoma, however, is known to differ depending on the anatomical site of the primary tumor, such as the tongue, gingiva, mouth floor, and buccal mucosa. In this study, we evaluated the applicability of this morphometric technique to evaluating the risk for cervical lymph node metastasis in oral squamous cell carcinoma. METHODS: A digital image system was used to measure the mean nuclear area, mean nuclear perimeter, nuclear circular rate, ratio of nuclear length to width (aspect ratio, and nuclear area coefficient of variation (NACV. Relationships between these parameters and nodal status were evaluated by t-test and logistic regression analysis. RESULTS: Eighty-eight cases of squamous cell carcinoma (52 of the tongue, 25 of the gingiva, 4 of the buccal mucosa, and 7 of the mouth floor were included: 46 with positive node classification and 42 with negative node classification. Nuclear area and perimeter were significantly larger in node-positive cases than in node-negative cases; however, there were no significant differences in circular rate, aspect ratio, or NACV. We derived two risk models based on the results of multivariate analysis: Model 1, which identified age and mean nuclear area and Model 2, which identified age and mean nuclear perimeter. It should be noted that primary tumor site was not associated the pN-positive status. There were no significant differences in pathological nodal status by aspect ratio, NACV, or primary tumor site. CONCLUSION: Our method of preoperative nuclear morphometry may contribute valuable information to evaluations of the risk for lymph node metastasis in oral squamous cell carcinoma.

    The differentiation between cervical intraepithelial neoplasia 3 (CIN 3) and early squamous cell carcinoma (SCC) of the cervix may be difficult in certain situations. Identification of invasion beyond the basement membrane is the gold standard for the diagnosis of the latter. The objective of this study was to determine whether the use of Ki-67 and p53 could help in solving the above dilemma. This was a retrospective study on 61 cases of cervical neoplasms comprising of 25 cases of CIN 3 and 36 SCC. All cases were evaluated by immunohistochemistry using Ki-67 and p53 monoclonal antibodies. Results showed that the differences of Ki-67 and p53 expression between CIN 3 and SCC were statistically significant. In conclusion, Ki-67 and p53 may serve as helpful adjuncts to routinely-stained histological sections in differentiating between CIN 3 and SCC.

    The purpose of this study was to analyze clinical outcomes from cervical cancer and stratify patients into risk groups for prognostic factors for early-stage disease. We retrospectively reviewed patients with stage IB or IIA cervical cancer treated with adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT) following primary surgery at Samsung Medical Center from 2001 to 2011. Adjuvant RT was added for patients with intermediate-risk factors, and adjuvant CCRT was performed on high-risk patients after surgery. We reviewed 247 patients—149 in the high-risk group and 98 in intermediate-risk group. The median follow-up was 62 months. Loco-regional failure (LRF) alone occurred in 7 patients (2.8%), distant metastasis alone in 37 patients (15.0%) and LRF with DM in 4 patients (1.6%). The 5-year disease-free survival (DFS) and overall survival (OS) rates for both groups were 79.7% and 87.6%, respectively. In the high-risk group, the 5-year DFS and OS probabilities were 72.5% and 81.9%, respectively. Histologic type, pathologic tumor size, and the number of pelvic lymph node (PLN) metastasis were significant prognostic factors for DFS and OS. We suggest a scoring system (0–3) using these prognostic factors to predict poor prognosis in high-risk patients. Using this system, patients with higher scores have higher recurrence and lower survival rates. In the high-risk cervical-cancer group who received primary surgery and adjuvant CCRT, non-squamous type, large tumor size and the number of PLN metastasis were significant prognostic factors, and the number of these factors was associated with survival rates.

  1. DNA Damage and Repair Biomarkers in Cervical Cancer Patients Treated with Neoadjuvant Chemotherapy: An Exploratory Analysis.

    Directory of Open Access Journals (Sweden)

    Patrizia Vici

    Full Text Available Cervical cancer cells commonly harbour a defective G1/S checkpoint owing to the interaction of viral oncoproteins with p53 and retinoblastoma protein. The activation of the G2/M checkpoint may thus become essential for protecting cancer cells from genotoxic insults, such as chemotherapy. In 52 cervical cancer patients treated with neoadjuvant chemotherapy, we investigated whether the levels of phosphorylated Wee1 (pWee1, a key G2/M checkpoint kinase, and γ-H2AX, a marker of DNA double-strand breaks, discriminated between patients with a pathological complete response (pCR and those with residual disease. We also tested the association between pWee1 and phosphorylated Chk1 (pChk1, a kinase acting upstream Wee1 in the G2/M checkpoint pathway. pWee1, γ-H2AX and pChk1 were retrospectively assessed in diagnostic biopsies by immunohistochemistry. The degrees of pWee1 and pChk1 expression were defined using three different classification methods, i.e., staining intensity, Allred score, and a multiplicative score. γ-H2AX was analyzed both as continuous and categorical variable. Irrespective of the classification used, elevated levels of pWee1 and γ-H2AX were significantly associated with a lower rate of pCR. In univariate and multivariate analyses, pWee1 and γ-H2AX were both associated with reduced pCR. Internal validation conducted through a re-sampling without replacement procedure confirmed the robustness of the multivariate model. Finally, we found a significant association between pWee1 and pChk1. The message conveyed by the present analysis is that biomarkers of DNA damage and repair may predict the efficacy of neoadjuvant chemotherapy in cervical cancer. Further studies are warranted to prospectively validate these encouraging findings.

    The objective of this study was to determine the five-year survival among patients with cervical cancer treated in Hospital Universiti Sains Malaysia. One hundred and twenty cervical cancer patients diagnosed between 1st July 1995 and 30th June 2007 were identified. Data were obtained from medical records. The survival probability was determined using the Kaplan-Meier method and the log-rank test was applied to compare the survival distribution between groups. The overall five-year survival was 39.7% [95%CI (Confidence Interval): 30.7, 51.3] with a median survival time of 40.8 (95%CI: 34.0, 62.0) months. The log-rank test showed that there were survival differences between the groups for the following variables: stage at diagnosis (p=0.005); and primary treatment (p=0.0242). Patients who were diagnosed at the latest stage (III-IV) were found to have the lowest survival, 18.4% (95%CI: 6.75, 50.1), compared to stage I and II where the five-year survival was 54.7% (95%CI: 38.7, 77.2) and 40.8% (95%CI: 27.7, 60.3), respectively. The five-year survival was higher in patients who received surgery [52.6% (95%CI: 37.5, 73.6)] as a primary treatment compared to the non-surgical group [33.3% (95%CI: 22.9, 48.4)]. The five-year survival of cervical cancer patients in this study was low. The survival of those diagnosed at an advanced stage was low compared to early stages. In addition, those who underwent surgery had higher survival than those who had no surgery for primary treatment.

    Full Text Available The association of human papilloma virus (HPV infection and cervical intraepithelial neoplasia (CIN is well recognized. Interaction of HPV oncogenic proteins with cellular regulatory proteins leads to up regulation of p16 INK4A , a CDK inhibitor, which is a biomarker for HPV infection. We investigated p16 expression in CIN and invasive squamous cell carcinoma (SCC which has not been reported in the Indian population previously. Materials and Methods: Retrospective analysis of 100 cases with 20 cases each of histologically normal cervical epithelium, CIN1, 2, 3 and invasive SCC for p16 expression was performed by immunohistochemistry using commercially available mouse monoclonal antibody to p16 (clone 6H12. Statistical Analysis: For differences in expression among groups, statistical analysis was carried out using ANOVA and post hoc test of Scheffe. Results: p16 immunoreactivity was found to be both nuclear and/or cytoplasmic. The normal cervical epithelium was predominantly negative for p16 (18/20. There was a progressive increase of p16 expression with the grade of CIN. In CIN 1, two cases (20% showed nuclear and nucleocytoplasmic positivity respectively. In contrast, diffuse strong nuclear or nucleocytoplasmic expression was observed in 45 and 55% cases of CIN 2 and CIN 3 respectively. All except one squamous cell carcinoma stained strongly positive for p16. The difference in expression between CIN 2/3 and SCC versus normal cervix was found highly significant (p is equal to 0.008 and p less than 0.001. Conclusions: p16 expression correlates excellently with the grade of CIN and is a sensitive marker of cervical intraepithelial neoplasia.

    To evaluate the value of apparent diffusion coefficient (ADC) histogram analysis for predicting tumor recurrence in patients with uterine cervical cancer treated with chemoradiation therapy (CRT). Our institutional review board approved this retrospective study and waived informed consent from each patient. Forty-two patients (mean age, 56 ± 14 years) with biopsy-proven uterine cervical squamous cell carcinoma who underwent both pre-treatment pelvic magnetic resonance imaging with a 3.0 T magnetic resonance scanner and concurrent CRT were included. All patients were followed-up for more than 6 months (mean, 36.4 ± 11.9 months; range 9.0-52.8 months) after completion of CRT. Baseline ADC parameters (mean ADC, 25th percentile, 50th percentile, and 75th percentile ADC values) of tumors were calculated and compared between the recurrence and no recurrence groups. In the recurrence group, the mean ADC and 75th percentile ADC values of tumors were significantly higher than those of the no recurrence group (p = 0.043 and p = 0.008, respectively). In multivariate analysis, the 75th percentile ADC value of tumors was a significant predictor for tumor recurrence (p = 0.009; hazard ratio, 1.319). When the cut-off value of the 75th percentile ADC (0.936 x 10{sup -3} mm{sup 2}/sec) was used, the overall recurrence free survival rate above the cut-off value was significantly lower than that below the cut-off value (51.9% vs. 91.7%, p = 0.003, log-rank test). Pre-CRT ADC histogram analysis may serve as a biomarker for predicting tumor recurrence in patients with uterine cervical cancer treated with CRT.

    Computer analysis of protein phosphorylation-sites sequence revealed that most transcriptional factors and viral oncoproteins are prime targets for regulation of proline-directed protein phosphorylation, suggesting an association of proline-directed protein kinase (PDPK) family with neoplastic transformation and tumorigenesis. In this report, an immunoprecipitate activity assay of protein kinase FA/glycogen synthase kinase-3alpha (kinase FA/GSK-3alpha) (a particular member of PDPK family) has been optimized for human cervical tissue and used to demonstrate for the first time significantly increased (P < 0.001) activity in poorly differentiated cervical carcinoma (82.8 +/- 6.6 U/mg of protein), moderately differentiated carcinoma (36.2 +/- 3.4 U/mg of protein), and well-differentiated carcinoma (18.3 +/- 2.4 U/mg of protein) from 36 human cervical carcinoma samples when compared to 12 normal controls (4.9 +/- 0.6 U/mg of protein). Immunoblotting analysis further revealed that increased activity of kinase FA/GSK-3alpha in cervical carcinoma is due to overexpression of protein synthesis of the kinase. Taken together, the results provide initial evidence that overexpression of protein synthesis and cellular activity of kinase FA/GSK-3alpha may be involved in human cervical carcinoma dedifferentiation/progression, supporting an association of proline-directed protein kinase with neoplastic transformation and tumorigenesis. Since protein kinase FA/GSK-3alpha may function as a possible regulator of transcription factors/proto-oncogenes, the results further suggest that kinase FA/GSK-3alpha may play a potential role in human cervical carcinogenesis, especially in its dedifferentiation and progression.

    To provide retrospective, descriptive information on patients with cervical necrotizing fasciitis treated at a single center during the years 1998-2014, and to evaluate the outcome of a newly introduced treatment strategy. Retrospective analysis of clinical data obtained from medical records. Mortality, pre-morbidity, severity of illness, primary site of infection, type of bacteria, time parameters. The observed 3-month mortality was 6/59 (10 %). The most common initial foci of the infection were pharyngeal, dental or hypopharyngeal. The most common pathogen was Streptococcus milleri bacteria within the Streptococcus anginosus group (66 % of the cases). Using a combined treatment with early surgical debridement combined with hyperbaric oxygen treatment, it is possible to reduce the mortality rate among patients suffering from cervical necrotizing fasciitis, compared to the expected mortality rate and to previous historical reports. Data indicated that early onset of hyperbaric oxygen treatment may have a positive impact on survival rate, but no identifiable factor was found to prognosticate outcome.

    Full Text Available Integration of human papillomavirus (HPV DNA into the host genome is a critical aetiological event in the progression from normal cervix to intraepithelial neoplasm, and finally to invasive cervical cancer. However, there has been little work on how HPV integration status relates to treatment outcome for cervical carcinomas. In the current study, HPV E2 and E6 gene copy numbers were measured in 111 cervical cancer tissues using real-time QPCR. Integration patterns were divided into four groups: single copy-integrated with episomal components (group 1, single copy-integrated without episomal components (group 2, multicopy tandem repetition-integrated (group 3, and low HPV (group 4 groups. A relapse-predicting model was constructed using multivariable Cox proportional hazards model to classify patients into different risk groups for disease-free survival (DFS. The model was internally validated using bootstrap resampling. Oligonucleotide microarray analysis was performed to evaluate gene expression patterns in relation to the different integration groups. DFS rate was inferior in the order of the patients in group 4, group 2/3, and group 1. Multivariate analysis showed that histologic grade, clinical stage group, and integration pattern were significant prognostic factors for poor DFS. The current prognostic model accurately predicted the risk of relapse, with an area under the receiver operating characteristic curve (AUC of 0.74 (bootstrap corrected, 0.71. In conclusion, these data suggest that HPV integration pattern is a potent prognostic factor for tailored treatment of cervical cancer.

    Full Text Available Background: Epithelial-to-mesenchymal transition (EMT plays a prominent role in tumorigenesis. Metformin exerts antitumorigenic effects in various cancers. This study investigated the mechanisms of metformin in TGF-β1-induced Epithelial-to-mesenchymal transition (EMT in cervical carcinoma cells. Methods: cells were cultured with 10 ng/mL TGF-β1 to induce EMT and treated with or without metformin. Cell viability was evaluated by CCK-8 (Cell Counting Kit 8, CCK-8 assay; apoptosis were analyzed by flow cytometry; cell migration was evaluated by wound-healing assay. Western blotting was performed to detect E-cadherin, vimentin, signal transducer and activator of transcription 3 (STAT3, snail family transcriptional repressor 2 (SNAIL2, phosphorylation of p70s6k (p-p70s6k and -Pyruvate kinase M2 (PKM2 Results: TGF-β1 promoted proliferation and migration, and it attenuated apoptosis compared with cells treated with metformin with or without TGF-β1 in cervical carcinoma cells. Moreover, metformin partially abolished TGF-β1-induced EMT cell proliferation and reversed TGF-β1-induced EMT. In addition, the anti-EMT effects of metformin could be partially in accord with rapamycin, a specific mTOR inhibitor. Metformin decreased the p-p70s6k expression and the blockade of mTOR/p70s6k signaling decreased PKM2 expression. Conclusion: Metformin abolishes TGF-β1-induced EMT in cervical carcinoma cells by inhibiting mTOR/p70s6k signaling to down-regulate PKM2 expression. Our study provides a novel mechanistic insight into the anti-tumor effects of metformin.

    The purpose of this study was to investigate the efficacy of dynamic MR imaging in the assessment of parametrial involvement by cervical carcinoma with full-thickness stromal invasion on thin-section oblique axial T2-weighted images. Dynamic MR images of 24 patients with cervical carcinoma with full-thickness stromal invasion on thin-section oblique axial T2-weighted images were evaluated with pathologic correlation. Dynamic MR imaging was performed using turbo fast low angle shot (FLASH), three-dimensional fast imaging with steady state procession (3D-FISP), or two-dimensional (2D)-FLASH technique. The imaging planes of dynamic MR imaging were oblique axial planes of the uterine cervix. Dynamic MR imaging was performed twice, once for the early phase (40 to 60 sec after the administration of contrast media) and once for the late phase (5 min). Contrast enhancement of the tumor was divided into six types. Type I, cervical stroma with low signal intensity surrounding a tumor with high signal intensity, was seen in the early phase of dynamic MR imaging; type II-RR, the hyperintense rim was seen from the early phase to the late phase; type II-RO, the hyperintense rim was seen in the early phase only; type II-OR, the hyperintense rim was seen in the late phase only; type II-O, the hyperintense rim was not seen at all; and type III, tumor invasion with high signal intensities was seen beyond the cervical stroma in the early phase of dynamic MR imaging. The numbers for each type of cervical carcinoma on dynamic MR images were as follows: type I, four parametrial sites; type II-RR, 0; type II-RO, 0; type II-OR, 13; type II-O, 14; and type III, one. Three-dimensional diameters (transverse, craniocaudal, and anteroposterior) of the primary tumor were measured using dividers. All parametrial sites of type I and type II-OR showed no parametrial involvement. One parametrial site of type III and three parametrial sites of type II-O showed parametrial involvement, and 11 of type

  20. Prebiotics: A Novel Approach to Treat Hepatocellular Carcinoma

    2017-01-01

    Full Text Available Hepatocellular carcinoma is one of the fatal malignancies and is considered as the third leading cause of death. Mutations, genetic modifications, dietary aflatoxins, or impairments in the regulation of oncogenic pathways may bring about liver cancer. An effective barrier against hepatotoxins is offered by gut-liver axis as a change in gut permeability and expanded translocation of lipopolysaccharides triggers the activation of Toll-like receptors which stimulate the process of hepatocarcinogenesis. Prebiotics, nondigestible oligosaccharides, have a pivotal role to play when it comes to inducing an antitumor effect. A healthy gut flora balance is imperative to downregulation of inflammatory cytokines and reducing lipopolysaccharides induced endotoxemia, thus inducing the antitumor effect.

    Cervical cancer is the third most common cancer in women worldwide. The hypermethylation of P16, TSLC-1 and TSP-1 genes was analyzed in squamous cell carcinomas (SCC), cervical intraepithelial lesions (CIN) and adenocarcinomas (ADC) of the uterine cervix (total 181 lesions). Additionally human papillomavirus (HPV) type, EPB41L3, RASSF1 and RASSF2 hypermethylation were tested in ADC and the results were compared with those obtained previously by our group in SCC. P16, TSLC-1 and TSP-1 hypermethylation was more frequent in SCCs than in CINs. These percentages and the corresponding ones for EPB41L3, RASSF1 and RASSF2 genes were also higher in SCCs than in ADCs, except for P16. The presence of HPV in ADCs was lower than reported previously in SCC and CIN. Patients with RASSF1A hypermethylation showed significantly longer disease-free survival (P = 0.015) and overall survival periods (P = 0.009) in ADC patients. To our knowledge, this is the first description of the EPB41L3 and RASSF2 hypermethylation in ADCs. These results suggest that the involvement of DNA hypermethylation in cervical cancer varies depending on the histological type, which might contribute to explaining the different prognosis of patients with these types of tumors.

    We aimed to delineate how pyrrolidine dithiocarbamate (PDTC) affects nuclear factor κB (NF-κB) and to determine its antitumor activity alone and in combination with cisplatin in human cervical cancer SiHa cells. The SiHa cells were treated with various concentrations of PDTC and/or cisplatin at various time intervals. Cell proliferation and apoptosis were determined using a water-soluble tetrazolium salt 8 assay and flow cytometry. Electrophoretic mobility shift assay was used to assess NF-κB activity. Pyrrolidine dithiocarbamate (2.5-100 µmol/L) was found to inhibit the growth of SiHa cell lines. Cisplatin (0.01-20.0 μg/mL) and PDTC (2.5-20.0 µmol/L) combined demonstrated additive inhibitive effects on cell growth and increased the level of apoptosis. In addition, PDTC blocked cisplatin-induced activation of NF-κB, leading to enhanced apoptosis and increased chemosensitivity to cisplatin. Taken together, PDTC has significant potential as a chemotherapy agent, alone or in combination with cisplatin.

    From 1983 to 1998, 93 patients with hypopharyngeal carcinoma were treated at Sapporo Medical University Hospital. Piriform sinus carcinoma was the most unfavorable prognostic location among the subsites. Also, the prognosis of patients with positive cervical lymph nodes and/or stage IV was poor. Forty-nine patients with N2 piriform sinus carcinoma were analyzed. Eleven (22.4%) had double cancers. Early T stages were curable with radiotherapy. However, the patients with positive cervical lymph nodes must be treated with radical neck dissection. Patients with good response at the time of 40 Gy had better survival rate than those with poor response. (author)

    Cervical carcinoma is the most common malignant tumor among woman in Paraguay. Cytological screening programs have not been successful and a plan for human papillomavirus (HPV) based-screening program and/or vaccination is under evaluation. This study aimed to identify the contribution of HPV genotypes in invasive cervical cancer in Paraguay to provide essential background data to guide and assess the introduction and impact of new preventive strategies based on HPV. Four hundred thirty two histologically confirmed cases (1960-2004) were analyzed. HPV detection in paraffin blocks was performed at the Catalan Institute of Oncology using PCR with SPF-10 broad spectrum primers followed by DNA enzyme immunoassay and genotyping with a reverse hybridization line probe analysis. The majority of cases were squamous cell carcinoma (92.8%). Mean patients age was 48 years old. HPV DNA was detected in 73.1% of the cases and single infections were predominant (97.8%). The most common HPV single types were 16, 18, 45, 33, 31, 52, 35, and 39. 73.1% of HPV positive cases had an HPV 16, 18 as single infection. HPV16 was frequent in SCC whereas HPV 18 and 45 were prevalent in glandular tumors. Significant decrease of HPV 16 with age groups (P-trend = 0.022) and increase in other HPV types (P-trend > 0.001) were observed. The potential impact of HPV 16 and 18 for a vaccination program was 73.1%. The study provide a profile of the HPV situation in the country, with robust clinical, pathological and virological data which would permit a better cervical cancer screening and vaccination programs.

    Objective To evaluate the clinical outcomes of surgical therapy in treating traumatic instability of subaxial cervical spine through either anterior or posterior approach. Methods according to the allen-Fergurson's classification, we retrospectively studied 42 cases of traumatic instability of subaxial cervical spine through either anterior or posterior surgical reconstruction. Patients requiring approach for either reduction or decompression were not included.Results The average follow-up interval was 3 years and 2 months. The anterior and posterior reconstructions were 24 and 18 cases, respectively. Before operation, the average scores of JOA and VAS were: 12.1 and 6.9 for anterior group, and 12.3 and 7.2 for posterior group. At the final assement, the scores of JOA and VAS improved to 16.0 and 2.2 for anterior group, and 15.7 and 2.6 for posterior group. The average ASIA motor scores of anterior and posterior group improved to 68.2 and 65.5 at the final follow-up from 58.4 and 59.7 before operation, respectively. The ASIA grade (A-E) was converted to a numeric score. The average scores before operation in the anterior and posterior group were 3.3 and 3.4, and increased to 3.8 and 3.7 at the final follow-up. After operation, there were different extent improvements of average radiological parameter, such as Cobb angle, vertebral body translation and disc height ratio. The average operation time and blood losing were 122 min and 125 mL for anterior group, and 153 min and 287 mL for posterior group. Fusion was achieved in all patients and 4 and 2 complications occurred at the anterior or posterior group.Conclusion The results showed that there were no obvious difference in parameters, such as neurological assements, functional grades, fusion rate, operation time and blood losing, between anterior and posterior group, except the virtues of anterior group in reconstruction and maintaining physiologic cervical lordosis and intervertrbal disc height occurred.

    Full Text Available Abstract Background Papillary renal cell carcinoma is a rare cancer. Some cases can be attributed to individuals with hereditary renal cell carcinomas usually consisting of the clear cell subtype. In addition, two syndromes with hereditary papillary renal cell carcinoma have been described. One is the hereditary leiomyomatosis and renal cell carcinoma, which is characterized by cutaneous and uterine leiomyomas and renal cell carcinoma mostly consisting of the papillary renal cell carcinoma type II with a worse prognosis. Case presentation We describe a case of a 30-year-old woman with hereditary leiomyomatosis and renal cell carcinoma syndrome with extensively metastasized papillary renal cell carcinoma, primarily diagnosed in a cervical lymph node lacking leiomyomas at any site. Conclusion Papillary renal cell carcinoma in young patients should be further investigated for a hereditary variant like the hereditary leiomyomatosis and renal cell carcinoma even if leiomyomas could not be detected. A detailed histological examination and search for mutations is essential for the survival of patients and relatives.

    Standard therapy has not been established for thyroid cancer when a thyroidectomy is contraindicated due to systemic disease. Herein, we reported a patient who had hypertrophic cardiomyopathy and papillary thyroid carcinoma treated by radiofrequency ablation because of inability to tolerate a thyroidectomy. Radiofrequency ablation can be used to treat thyroid cancer when surgery is not feasible, although the long-term outcome needs further observation.

    Strong evidence exists that the host's immune system plays a crucial role for the development of human papillomavirus-related cervical premalignant and malignant lesions. In particular, effective cell-mediated immunity (CMI) promotes spontaneous infection clearance and cancer precursors regression in healthy subjects, while immunosuppressed individuals are more likely to experience infection persistence, cervical intraepithelial neoplasia (CIN) lesions, and cervical cancer. In this study, the...

    As the number of long-term cervical cancer survivors continues to increase because of improvements in treatment, concerns about second primary malignancy have grown. The high-risk area of second primary cancers in cervical cancer survivors is the pelvis. Pelvic inflammatory disease (PID) could be a useful marker for gynecological cancers. Thus, we designed a large-scale, nationwide, controlled cohort study to investigate whether PID or other risk factors increased the risk of second primary cancers in patients with cervical cancer treated by surgery alone.Between 2000 and 2010, a total of 24,444 cervical cancer patients were identified using the Registry Data for Catastrophic Illness and the National Health Insurance Research Database (NHIRD) of Taiwan. Patients who received definite surgery were selected. To exclude the effect on second primary malignancy by treatment modalities, all cervical patients who ever having received adjuvant or definite radiotherapy or chemotherapy for primary cervical cancer were excluded. Finally, 3860 cervical cancer patients treated by surgery alone without adjuvant treatments were analyzed.Cox proportional hazards model was used for multivariate analysis and the Kaplan-Meier method was used to assess the cumulative risks. Regarding the incidence of second primary cancers, the standardized incidence ratio (SIR) was used.The median follow-up time was 56.6 months. The 6-year cumulative risk of second primary cancers is 0.16% and 0.12% for PID and without PID, respectively. After adjustment for confounders, age of less than 50 years, the presence of diabetes mellitus, and PID were significantly positivity associated with the risk of second primary cancers. The hazard ratios (HRs) of age less than 50 years, diabetes mellitus, and PID were 1.38 (95% CI = 1.11-2.04), 1.40 (95% CI = 1.06-1.85), and 1.35 (95% CI = 1.00-1.81), respectively. A higher incidence of second primary cancers was observed in the genitals, bladder, and

    In 1% to 3% of patients with cervical intraepithelial neoplasia (CIN), vaginal intraepithelial neoplasia (VAIN) will either coexist or occur at a later date. The time interval from an earlier diagnosis of CIN 3 to a current diagnosis of VAIN 3 varies from two to 17 years. Invasive vaginal cancer occurred in a woman five years after total abdominal hysterectomy for cervical intraepithelial neoplasia. In women who have undergone total hysterectomy for cervical intraepithelial neoplasia or cervical cancer, postoperative cytologic and colposcopic follow-up of the vagina is necessary.

    Full Text Available Matrix metalloproteinases (MMPs, a family of proteolytic enzymes produced by both stromal and tumor cells, appear to have a key role in the events leading to local invasion and metastasis by malignant neoplasms. In the present study, we evaluated the role of MMP-2, squamous cell carcinoma antigen (SCCA, and tissue polypeptide – specific antigen (TPS in cervical neoplasia. Using Western blotting and enzyme immunoassay (EIA, we analyzed 50 patients with cervical carcinoma (CC and 25 normal controls for expression of MMP-2 in tissue cell lysates. We also quantified SCCA and TPS with microparticle immunoassay and EIA, respectively. The results were correlated with human papilloma virus (HPV infection, clinicopathological findings, and disease outcome. The cutoff point for each marker was estimated from receiver operating characteristic curves. Logistic regression analysis was performed to estimate the odds ratio (OR and 95% confidence interval (CI for each marker. MMP-2, SCCA, and TPS protein expression were significantly higher in patients with CC than in normal controls. While TPS was the best marker for discriminating between patients and controls, MMP-2 was associated with an advanced tumor stage (OR, 13.9 [95% CI, 1.4-133.9] and poor histological grade (OR, 10.2 [95% CI, 1.7-60.5]. Moreover, independent of the effect of an advanced CC stage and grade, the patients' age, and the presence of HPV infection, MMP-2 was considered a strong predictor for CC recurrence (OR, 8.1 [95% CI, 1.3- 49.1]. Tissue markers may be used to select high-risk patients for early detection of and adjuvant therapy for recurrence. Our MMP-2 findings are particularly relevant to the development of protease inhibitors as a new cancer therapy approach.

    Forkhead box M1 (FOXM1) and hedgehog (Hh) signaling pathway are implicated in the formation and development of human tumors, including cervical cancer. Previous studies have indicated that FOXM1 may be a downstream target gene of the Hh signaling pathway, but their association in cervical cancer is largely unknown. In the present study, the expression of FOXM1 and Hh signaling molecules was evaluated by immunohistochemical analysis in a tissue microarray that contained 70 cervical cancer tissues and 10 normal cervical tissues. In addition, the association of these molecules with clinicopathological parameters, and the association between FOXM1 and various molecules involved in the Hh signaling pathway was investigated. The results indicated that FOXM1 and Hh signaling molecules were overexpressed in cervical cancer tissues. The protein expression levels of FOXM1, glioma-associated oncogene 1 (GLI1) and smoothened (SMO) correlated with the clinical stage of the tumors, while the protein expression levels of Sonic Hh (SHh), patched 1 (PTCH1) and GLI1 correlated with the pathological grade of the tumors. The expression levels of GLI1 were lower in tissues without lymph node metastasis than in tissues with lymph node metastasis. In addition, FOXM1 expression correlated with GLI1, SHh and PTCH1 expression in cancer tissues. These findings confirmed the participation of FOXM1 and the Hh signaling pathway in cervical cancer. Furthermore, the finding that FOXM1 may be a downstream target gene of the Hh signaling pathway in cervical cancer provides a potential novel diagnostic and therapeutic target for cervical cancer.

    MicroRNAs are involved in cancer-related processes. The microRNA-21(miR-21) has been identified as the only miRNA over-expressed in a wide variety of cancers, including cervical cancer. However, the function of miR-21 is unknown in cervical carcinomas. In this study, we found that the inhibition of miR-21 in HeLa cervical cancer cells caused profound suppression of cell proliferation, and up-regulated the expression of the tumor suppressor gene PDCD4. We also provide direct evidence that PDCD4-3'UTR is a functional target of miR-21 and that the 18 bp putative target site can function as the sole regulatory element in HeLa cells. These results suggest that miR-21 may play an oncogenic role in the cellular processes of cervical cancer and may serve as a target for effective therapies.

    Cardiac metastasis from renal cell carcinoma, especially without neoplastic thrombosis of the vena cava, is extremely rare. The prognosis of patients with metastatic renal cell carcinoma has been radically influenced by the introduction of tyrosine kinase inhibitors, but very few reports in the literature have described their activity in heart metastasis. We report the case of a woman with a left ventricle metastasis from kidney cancer without renal vein involvement, who was treated with pazopanib. The patient achieved a prolonged partial response, with clear signs of metastasis devascularization and a favorable toxicity profile.

    Undifferentiated gastric carcinoma is a rare histopathological type of cancer that does not show any differentiation toward adenocarcinoma or squamous cell carcinoma. It is thought to be highly malignant, and is associated with a poor prognosis. However, its clinical behavior has not yet been fully analyzed because of its rarity. We herein review the clinical characteristics and prognoses of patients with undifferentiated gastric carcinoma treated at our institutions. Among 2,651 gastric cancer patients, four (0.2 %) were histopathologically diagnosed to have undifferentiated carcinoma. These four patients included three males and one female. The median age of the patients was 60-year old (range 47-75). Three cases had distant metastases at diagnosis. One of these three cases was treated with chemotherapy alone, and the other two were treated with palliative gastrectomy and chemotherapy. The patient with no distant metastasis underwent curative gastrectomy and adjuvant chemotherapy. All patients died of cancer at a median of 5.4 (range 3.5-7.1) months after their diagnoses.

    OBJECTIVE To investigate the factors that can accurately predict the prognosis for patients with FIGO stage-IB cervical squamous cell carcinoma treated with radical surgery.METHODS A retrospective analysis of clinical data from 174 cases of FIGO Stage-IB cervical squamous cell carcinoma treated in our institute was conducted.RESULTS The 5-year overall disease-free survival of the patients was 79.4% and the recurrence rate was 16.7%. Seventy-five percent of the 60 patients with a tumor > 4 cm and 28.1% of the 114 patients with a tumor ≤ 4 cm received preoperative radiotherapy, resuting in a significant difference between the two groups (P < 0.001). The 5-year disease-free survival rate for the groups with a tumor ≤ 4 cm without and with preoperative radiotherapy, and with a tumor > 4 cm without and with preoperative radiation therapy were 80.5%, 85.2%, 69.3% and 77.1%, respectively. There was no significant difference between any of the groups (P > 0.05). A univariate analysis showed that pelvic node metastasis, a positive parametrial surgical margin and postoperative adjuvant therapy were all significantly correlated with the 5-year disease-free survivals (P < 0.05). Multivariate analysis revealed that pelvic node metastasis (P = 0.004) and a positive parametrial surgical margin (P = 0.040) were independent factors that influenced the prognosis. The 5-year disease-free survivals for the cases with a tumor ≤ 4 cm and > 4 cm were 57.4% and 44.7% respectively in the high-risk group (patients with pelvic lymphatic metastasis and/or positive parametrial surgical margin) (P=0.575) and the recurrence ratio was 7/18 and 6/14 for the cases of the two tumor sizes in the same risk group. There was no significant difference between the two groups (P=0.821). The 5-year disease-free survivals for the cases with a tumor ≤ 4 cm and > 4 cm were 86.5% and 82.9% respectively in the low-risk group (patients without pelvic lymph-node metastasis and/or positive

    Full Text Available Background: Pelvic lymph node metastasis (LNM is an important prognostic factor in cervical cancer. Cervical squamous cell carcinoma accounts for approximately 75-80% of all cervical cancers. Analyses of the effects of the number of positive lymph nodes (LNs, unilateral versus bilateral pelvic LNM and a single group versus multiple groups of pelvic LNM on survival and recurrence of cervical squamous cell carcinoma are still lacking. The study aimed to analyze the effects of the number of positive pelvic LNs and a single group versus multiple groups of pelvic LNM on survival and recurrence. Methods: We performed a retrospective review of 296 patients diagnosed with Stage IA-IIB cervical squamous cell carcinoma who received extensive/sub-extensive hysterectomy with pelvic lymphadenectomy/pelvic LN sampling at Peking University People′s Hospital from November 2004 to July 2013. Ten clinicopathological variables were evaluated as risk factors for pelvic LNM: Age at diagnosis, gravidity, clinical stage, histological grade, tumor diameter, lymph-vascular space involvement (LVSI, depth of cervical stromal invasion, uterine invasion, parametrial invasion, and neoadjuvant chemotherapy. Results: The incidence of pelvic LNM was 20.27% (60/296 cases. Pelvic LNM (P = 0.00 was significantly correlated with recurrence. Pelvic LNM (P = 0.00, the number of positive pelvic LNs (P = 0.04 and a single group versus multiple groups of pelvic LNM (P = 0.03 had a significant influence on survival. Multivariate analysis revealed that LVSI (P = 0.00, depth of cervical stromal invasion (P = 0.00 and parametrial invasion (P = 0.03 were independently associated with pelvic LNM. Conclusions: Patients with pelvic LNM had a higher recurrence rate and poor survival outcomes. Furthermore, more than 2 positive pelvic LNs and multiple groups of pelvic LNM appeared to identify patients with worse survival outcomes in node-positive IA-IIB cervical squamous cell carcinoma.

    The yields of dicentric and ring chromosomes were recorded during telecobalt therapy for mammary carcinoma. The data were fitted to a power or a quadratic function and were compared with those obtained in patients treated for ankylosing spondylitis and nuclear dockyard workers as well as with the results of an in vitro blood irradiation. As expected, the aberration yield for the same absorbed dose level is much greater after irradiation of ankylosing spondylitis than after irradiation for mammary carcinoma; lymphocytes exposed in vitro display the highest rate of aberration. A deviation of the aberrations observed in cells of the mammary carcinoma patients from the theoretical Poisson distribution also indicates that not all lymphocytes in the body has been exposed under these conditions.

    Retrospective study The authors' aim of the present study is to report their experience with subaxial cervical synovial cysts hoping to provide further insight into these lesions including the presenting symptoms, possible mechanisms of cyst development associated with cervical level, surgical treatments and clinical outcomes. Synovial cysts are relatively common in the lumbar spine and very uncommonly identified in the subaxial cervical spine. Several case reports and a few small series have been reported in the literature over the past four decades. The authors retrospectively reviewed the cases of 35 patients who underwent surgical treatment for histologically confirmed symptomatic subaxial cervical synovial cysts between 1993 and 2009. The presenting symptoms, age, sex, cervical level, operation, complications and outcomes were analyzed in this cohort. Preoperative and postoperative neurologic assessments were done by staff neurologists independent of the operating surgeon. This study was approved by the Mayo Clinic institutional review board. Thirty-five patients underwent surgical treatment for their synovial cysts and follow-up for at least 12 months postoperatively. The mean follow-up time was 49 months (range, 12-134). There were no deaths associated with the surgery. There was one postoperative infection in a patient undergoing a decompressive laminectomy and posterior instrumented fusion. Patient outcomes were assessed using the Modified Rankin Score for 12 patients was 0, 17 patients was 1, 4 patients was 2, and 2 patients was 3. This series of 35 patients with subaxial cervical synovial cysts surgically treated over a period of 17 years illustrates the relative rarity of these lesions. Magnetic resonance imaging is currently the optimal radiographic study to identify these lesions. Surgical resection can be an effective treatment.

    The uptake of the rhenium-188 ({sup 188}Re(V)-DMSA) complex of dimercaptosuccinic acid by cervical carcinoma cells in nude mice was evaluated. The pharmacokinetics and dosimetry calculations in normal rats were also evaluated. The images obtained in mice did not show significant accumulation in metabolic organs and the biodistribution studies showed that 3.52{+-}0.76% of the injected activity per gram (n=4) was taken up by the tumor. This percentage produces a cumulated activity of 35.63{+-}8.40 MBq h and an equivalent dose per injected activity of 260{+-}8.91 mSv/MBq. Pharmacokinetics and dosimetry of the {sup 188}Re(V)-DMSA complex indicate that this radiopharmaceutical could be evaluated in patients with soft tissue tumors, since the risk of radiation damage to the kidney or red bone marrow could not be an obstacle for its application in therapeutic nuclear medicine.

    Objectives To investigate the clinical value of combined dye-isotope technique in detecting sentinel lymph node (SLN) and to examine whether the characteristics of SLN accurately predict cervical lymph node metastasis in lingual carcinoma. Methods Thirty patients with lingual carcinoma without lymph metastasis were injected with a dose of about 18.5 MBq of 99mTc-SC (sulfur colloid), around the tumor tissues before surgery, and lymphoscintigraphy was performed 5, 10, 30, 60 minutes, and 6 hours after injection. In the following day, all patients were injected with isosulfan blue dye around the primary tumor during surgery to trace SLN and underwent standard cervical lymph node dissection after SLN dissection. The pathological results of SLN were compared with standard lymph node dissection for their ability to accurately predict the final pathological status of the cervical lymph nodes.Results SLN was successfully identified in 100% of the patients. Both positive and negative predictive values of SLN were 100%. The accuracy rate was 100%, and there were no false negatives. Conclusions The detection of SLN using combined dye-isotope technique could accurately predict cervical lymph node metastasis in lingual carcinoma.

    Purpose: Different treatment planning systems (TPS) use different treatment optimization and leaf sequencing algorithms. This work compares cervical carcinoma IMRT plans optimized with four commercial TPSs to investigate the plan quality in terms of target conformity and delivery efficiency. Methods: Five cervical carcinoma cases were planned with the Corvus, Monaco, Pinnacle and Xio TPSs by experienced planners using appropriate optimization parameters and dose constraints to meet the clinical acceptance criteria. Plans were normalized for at least 95% of PTV to receive the prescription dose (Dp). Dose-volume histograms and isodose distributions were compared. Other quantities such as Dmin(the minimum dose received by 99% of GTV/PTV), Dmax(the maximum dose received by 1% of GTV/PTV), D100, D95, D90, V110%, V105%, V100% (the volume of GTV/PTV receiving 110%, 105%, 100% of Dp), conformity index(CI), homogeneity index (HI), the volume of receiving 40Gy and 50 Gy to rectum (V40,V50) ; the volume of receiving 30Gy and 50 Gy to bladder (V30,V50) were evaluated. Total segments and MUs were also compared. Results: While all plans meet target dose specifications and normal tissue constraints, the maximum GTVCI of Pinnacle plans was up to 0.74 and the minimum of Corvus plans was only 0.21, these four TPSs PTVCI had significant difference. The GTVHI and PTVHI of Pinnacle plans are all very low and show a very good dose distribution. Corvus plans received the higer dose of normal tissue. The Monaco plans require significantly less segments and MUs to deliver than the other plans. Conclusion: To deliver on a Varian linear-accelerator, the Pinnacle plans show a very good dose distribution. Corvus plans received the higer dose of normal tissue. The Monaco plans have faster beam delivery.

    Objective: To investigate the expression of p16 and GATA3 and the detection of human papillomavirus (HPV) in secondary bladder involvement by cervical carcinomas. Methods: Sixteen cases of cervical carcinoma with bladder involvement diagnosed from December 2008 to March 2016 were collected and evaluated by light microscopy, immunohistochemistry for p16 and GATA3 detection and PCR-reverse dot blot for molecular typing of HPV. Results: The age of the patients ranged from 25 to 76 years with median of 52 years. Morphologically, 14 cases(14/16) showed tumor nests infiltrating lamina propria or muscle bundles of the bladder. By immunohistochemistry, 15 cases (15/16) were found to be diffusely and strongly positive for p16, and 1 showed patchy staining pattern. Seven cases (7/7) of corresponding original cervical cancers were also diffusely and strongly positive for p16. GATA3 staining was negative in 13 cases (13/16), and focal weak to moderate positivity was detected in 3 cases.Three cases (3/7) of corresponding original cervical cancers showed focal weak to moderate positivity of GATA3. Fifteen cases (15/16) showed concordant high risk HPV-positivity, including HPV16 in 8 cases and HPV31 in one case. Five cases showed co-infection of HPV16 and HPV18. One case showed co-infection with HPV18 and HPV45. Conclusion: Differential diagnosis by p16 or GATA3 alone is of limited value. Combination of immunohistochemistry for p16 and GATA3 and molecular typing for HPV detection are useful to distinguish primary bladder carcinoma from the secondary involvement by cervical carcinoma.

    Current cervical cancer screening guidelines recommend screening with a Papanicolaou (Pap) test or by cotesting (Pap and human papillomavirus [HPV]). Given the importance of high-risk HPV (hrHPV) infection in the development of cervical cancer, some studies are now suggesting the use of primary hrHPV testing as a possible screening modality. To gain further insight into the role of both Pap testing and hrHPV testing, the authors examined prior screening results in a population of Chinese patients with invasive cervical carcinoma. Cases with a histologic diagnosis of invasive cervical carcinoma were retrieved from the Obstetrics and Gynecology Hospital of Fudan University from January 2011 to October 2014. Prior hrHPV testing and Pap test results within 3 years before the cancer diagnosis were recorded. Of 3714 patients with invasive cervical carcinoma, over a 46-month period, 525 had prior hrHPV testing using Hybrid Capture 2 within 3 years and 238 patients had Pap cytology testing within 1 year before the histological diagnosis. Within the 1-year period before diagnosis, the overall hrHPV-negative rate was 15.5% (74 of 477 patients) and the Pap-negative rate was also 15.5% (37 of 238 patients). Only 9 of 231 patients with both hrHPV testing and Pap testing (3.9%) had a double-negative result. Compared with squamous cell carcinoma, adenocarcinoma has significantly higher rates of prior negative results with both hrHPV and Pap cytology. The results of the current study demonstrated prior results of hrHPV testing and Pap cytology in a population of women in China who had not undergone intensive prior screening. Both hrHPV testing and Pap cytology were found to have similar negative rates in this population and, not surprisingly, there were fewer women who had negative testing results using both testing modalities. © 2015 American Cancer Society.

    Full Text Available Strong evidence exists that the host’s immune system plays a crucial role for the development of human papillomavirus-related cervical premalignant and malignant lesions. In particular, effective cell-mediated immunity (CMI promotes spontaneous infection clearance and cancer precursors regression in healthy subjects, while immunosuppressed individuals are more likely to experience infection persistence, cervical intraepithelial neoplasia (CIN lesions, and cervical cancer. In this study, the prognostic significance of immunohistochemical profiling of CD4+ T-cells, CD8+ T-cells, dendritic cells (CD11c+, T-bet+, and GATA-3+ transcription factors has been studied in surgical specimens of 34 consecutive women affected by high-grade cervical intraepithelial neoplasia (CIN2-3 submitted to cervical conization. Results have been correlated with the clinical outcomes at 24 months after treatment and statistically analyzed. Higher rates of CD4+ T-cells, CD11c+ dendritic cells, and T-bet+ transcription factor positivity showed a strong statistically significative correlation with favourable clinical outcomes (P≤0.0001. These data reinforce the evidence of the relevance of the host’s immune status in the natural history of HPV-related cervical disease and add a prognostic significance of the cervical immunological profile in terms of predicting significant lower recurrence rates.

    To describe human papillomavirus (HPV) distribution in invasive cervical carcinoma (ICC) from Mali and Senegal and to compare type-specific relative contribution among sub-Saharan African (SSA) countries. A multicentric study was conducted to collect paraffin-embedded blocks of ICC. Polymerase chain reaction, DNA enzyme immunoassay and line probe assay were performed for HPV detection and genotyping. Data from SSA (Mozambique, Nigeria and Uganda) and 35 other countries were compared. One hundred and sixty-four ICC cases from Mali and Senegal were tested from which 138 were positive (adjusted prevalence = 86.8%; 95% CI = 79.7-91.7%). HPV16 and HPV18 accounted for 57.2% of infections and HPV45 for 16.7%. In SSA countries, HPV16 was less frequent than in the rest of the world (49.4%vs. 62.6%; P < 0.0001) but HPV18 and HPV45 were two times more frequent (19.3%vs. 9.4%; P < 0.0001 and 10.3%vs. 5.6%; P < 0.0001, respectively). There was an ecological correlation between HIV prevalence and the increase of HPV18 and the decrease of HPV45 in ICC in SSA (P = 0.037 for both). HPV16/18/45 accounted for two-thirds of the HPV types found in invasive cervical cancer in Mali and Senegal. Our results suggest that HIV may play a role in the underlying HPV18 and HPV45 contribution to cervical cancer, but further studies are needed to confirm this correlation. © 2012 Blackwell Publishing Ltd.

    Purpose: To assess the effectiveness of high-dose-rate intracavitary radiotherapy (HDR-ICR) in patients with cervical intraepithelial neoplasia 3 (CIN 3) and carcinoma in situ (CIS) presenting with poor histologic factors for predicting residual disease after undergoing diagnostic excisional procedures. Methods and Materials: This study was a retrospective analysis of 166 patients with CIN 3 (n=15) and CIS (n=151) between October 1986 and December 2005. They were diagnosed by conization (n=158) and punch biopsy (n=8). Pathologic analysis showed 135 cases of endocervical gland involvement (81.4%), 74 cases of positive resection margins (44.5%), and 52 cases of malignant cells on endocervical curettage (31.3%). All patients were treated with HDR-ICR using Co{sup 60} or Ir{sup 192} at a cancer center. The dose was prescribed at point A located 2 cm superior to the external os and 2 cm lateral to the axis of the tandem for intact uterus. Results: Median age was 61 years (range, 29-77). The median total dose of HDR-ICR was 30 Gy/6 fractions (range, 30-52). At follow-up (median, 152 months), 2 patients developed recurrent diseases: 1 CIN 2 and 1 invasive carcinoma. One hundred and forty patients survived and 26 patients died, owing to nonmalignant intercurrent disease. Rectal bleeding occurred in one patient; however, this symptom subsided with conservative management. Conclusions: Our data showed HDR-ICR is an effective modality for CIN 3 and CIS patients presenting with poor histologic factors after excisional procedures. HDR-ICR should be considered as a definitive treatment in CIN 3 and CIS patients with possible residual disease after undergoing excisional procedures.

    . To explore the mechanism of repression of cell cycle genes in cervical carcinoma cells following E6/E7 repression, we analyzed regulation of the cdc25A promoter, which contains two consensus E2F binding sites and a consensus E2 binding site. The wild-type E2 protein inhibited expression of a luciferase gene...... E2F4-Rb DNA binding complexes. Importantly, these experiments revealed that HPV-induced alterations in E2F transcription complexes that occur during cervical carcinogenesis are reversed by repression of HPV E6/E7 expression....

    Cancer is a worldwide public health problem, its prevention and control are included within 16 strategic objectives of the Brazilian Ministry of Health for the period 2011-2015. Cervical cancer is the fourth most common tumor in the female population, being new 15,590 cases estimated for 2014 according to the Brazilian National Cancer Institute (INCA). Pernambuco is the fifth state with the highest number of cases of cervical cancer and the seventh in cases of endometrial ones, both estimative for 2014. The understanding of the epidemiological profile of these pathologies corroborates strategies for prevention, control and treatment. As Pernambuco has implemented the radiotherapy for cancer treatment since 1998-1999, this work encompassed the comparison of the 1998-1999 epidemiological profile of patients treated by radiotherapy for cervical and endometrial cancer in the State of Pernambuco, Brazil, with 2008-2009 profile - ten years after. Medical record of 490 patients treated at the Center of Radiotherapy of Pernambuco (CERAPE) were compiled according to the patient origin, the affected uterus region, the staging of disease, the type and cell differentiation of the tumor, the age group, and, finally, the realization of hysterectomy as part of the treatment. More than 90% of the patients were affected by cervical cancer in the two investigated periods. For the interval of 1998-1999 the proportion of patients submitted to hysterectomy was quite higher compared to those after ten years. The results also showed a change in the origin of the patients, in which, in 1999, most of the patients were from the capital and the metropolitan area, while, after ten years, patients were mostly from the interior of the State. There was a predominance of squamous cell type tumors in both periods evaluated. For the 1998-1999 interval, tumors were stage 2, moderately differentiated type. Differently, the tumors were mostly stage 3, not differentiated type, for the 2008-2009 period

    Chyle fistula is an uncommon serious complication of neck surgery, occurring in 1-3% of radical neck dissections. An untreated chyle leak is a potentially dangerous condition that may rarely lead to hypovolemia, hyponatremia, hypochloremia, hypoproteinemia and lymphopenia. Anatomic variants of the terminal portion of the thoracic duct and suction drainage in the neck wound play a primary role in causing this kind of lesion. Poor is the literature concerning chyle fistula, due to its rarity, and mostly case reports; still debated--prevalently empiric--is the management of this disease. The Authors report a case of chyle fistula following a reintervention of cervical bilateral lymphectomy for medullary carcinoma of the thyroid in a 75 years old female. In the reported case the chyle fistula was successfully treated conservatively, in early post-operative period with a low-fat diet and total parenteral nutrition, definitely followed by sclerosant therapy. The injection of a sclerosant agent (4 g of sterile medical talc diluted in isotonic sodium chloride solution) into the supraclavicular wound bed, through the drainage tube (clamped for 2 hours), determined rapid decline in fistula output, hence obviating surgical intervention.

    Tumor necrosis factor {alpha} (TNF-{alpha}) stimulated the phosphorylation of a 28-kDa protein (p28) in the ME-180 line of human cervical carcinoma cells. The effect of TNF-{alpha} on the phosphorylation state of p28 was rapid (4-fold increase within 15 min) and persistent, remaining above the basal level for at least 2 hr. The specific binding of {sup 125}I-labeled TNF-{alpha} to cell-surface binding sites, the stimulation of p28 phosphorylation by TNF-{alpha}, and the inhibition of cell proliferation by TNF-{alpha} occurred with nearly identical dose-response relationships. Two-dimensional SDS/PAGE resolved p28 into two isoforms having pI values of 6.2 and 6.1. A phosphorylated cap-binding protein was substantially enriched from lysates of control or TNF-{alpha}-treated ME-180 cells by affinity chromatography with 7-methylguanosine 5{prime}-triposphate-Sepharose. The phosphoprotein recovered from this procedure was the substrate for TNF-{alpha}-promoted phosphorylation, p28. Thus, TNF-{alpha} stimulates the phosphorylation of this mRNA cap-binding protein, which may be involved in the transduction of TNF-{alpha}-receptor binding into cellular responses.

    Full Text Available Abstract Background The purpose of this study was to investigate whether the excision repair cross-complementation group 1 (ERCC1 mRNA expression could predict treatment response of patients with locally advanced cervical squamous cell carcinoma (LACSCC who underwent cisplatin-based concurrent chemoradiotherapy (CCCRT. Methods A total of sixty LACSCC patients, treated with radical CCCRT from a single institution were evaluated. ERCC1 mRNA expression was determined by quantitative real-time RT-PCR in pre-treatment tumor tissues. The association of ERCC1 status with clinicopathological characteristics (age, histological grade, tumor size, parametrial invasion, lymph node metastasis and FIGO stage and treatment response were analyzed. Results No significant association between ERCC1 mRNA expression and clinicopathological characteristics were observed. Patients with low ERCC1 mRNA level had a significantly higher rate of complete response (86.21% than patients with high level of ERCC1 expression (19.36%; p P  Conclusions This is the first analysis of the association between ERCC1 mRNA levels and treatment response in patients with LACSCC. Low ERCC1 mRNA level appears to be a highly specific predictor of response to CCCRT in LACSCC.

    Full Text Available Cervical cancer remains the third most frequently diagnosed and fourth leading cause of cancer death in women worldwide. We sought to develop a micro-RNA signature that was prognostic for disease-free survival, which could potentially allow tailoring of treatment for cervical cancer patients. A candidate prognostic 9-micro-RNA signature set was identified in the training set of 79 frozen specimens. However, three different approaches to validate this signature in an independent cohort of 87 patients with formalin-fixed paraffin-embedded (FFPE specimens, were unsuccessful. There are several challenges and considerations associated with developing a prognostic micro-RNA signature for cervical cancer, namely: tumour heterogeneity, lack of concordance between frozen and FFPE specimens, and platform selection for global micro-RNA expression profiling in this disease. Our observations provide an important cautionary tale for future miRNA signature studies for cervical cancer, which can also be potentially applicable to miRNA profiling studies involving other types of human malignancies.

MÉTODOS: Avaliamos 16 pacientes com carcinoma do colo uterino atendidas no período de abril de 1986 a agosto de 1998, tratadas com irradiação pré-operatória e cirurgia. Após revisão histopatológica do material das biópsias e peças cirúrgicas, procedeu-se ao exame imuno-histoquímico para avaliar a expressão do PCNA. A imuno-expressão do PCNA foi analisada através do programa de análise gráfica por computador IMAGELAB 2.3. RESULTADOS: Em oito (50% casos detectou-se persistência de neoplasia e em outros oito (50% houve ausência de neoplasia residual. O valor médio do índice de PCNA anterior à radioterapia nos casos com tumor residual foi de 61,56% e, nos casos sem tumor residual, de 60%. A avaliação da expressão do PCNA nas 16 biópsias prévias à radioterapia mostrou valor médio de 60%. Nas peças de histerectomia com neoplasia residual a expressão do PCNA foi, em média, 74%. CONCLUSÕES: A associação de radioterapia pré-operatória e cirurgia no carcinoma do colo uterino permite adequada terapêutica em pacientes sem condições para a cirurgia radical. Outrossim, a radioterapia exclusiva apresenta percentagem relevante de insucessos detectados pela cirurgia e pela análise do PCNA.OBJECTIVE: To search for residual disease and to analyse the Proliferating Cellular Nuclear Antigen (PCNA status, in patients with cervical squamous cell carcinoma, treated with both radiotherapy and surgery.

    Full Text Available Abstract Background High interstitial fluid pressure (IFP in the primary tumor is associated with poor disease-free survival in locally advanced cervical carcinoma. A noninvasive assay is needed to identify cervical cancer patients with highly elevated tumor IFP because these patients may benefit from particularly aggressive treatment. It has been suggested that dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI with gadolinium diethylene-triamine penta-acetic acid (Gd-DTPA as contrast agent may provide useful information on the IFP of cervical carcinomas. In this preclinical study, we investigated whether DCE-MRI with contrast agents with higher molecular weights (MW than Gd-DTPA would be superior to Gd-DTPA-based DCE-MRI. Methods CK-160 human cervical carcinoma xenografts were subjected to DCE-MRI with Gd-DTPA (MW of 0.55 kDa or gadomelitol (MW of 6.5 kDa as contrast agent before tumor IFP was measured invasively with a Millar SPC 320 catheter. The DCE-MRI was carried out at a spatial resolution of 0.23 × 0.23 × 2.0 mm3 and a time resolution of 14 s by using a 1.5-T whole-body scanner and a slotted tube resonator transceiver coil constructed for mice. Parametric images were derived from the DCE-MRI recordings by using the Tofts iso-directional transport model and the Patlak uni-directional transport model. Results When gadomelitol was used as contrast agent, significant positive correlations were found between the parameters of both pharmacokinetic models and tumor IFP. On the other hand, significant correlations between DCE-MRI-derived parameters and IFP could not be detected with Gd-DTPA as contrast agent. Conclusion Gadomelitol is a superior contrast agent to Gd-DTPA in DCE-MRI of the IFP of CK-160 cervical carcinoma xenografts. Clinical studies attempting to develop DCE-MRI-based assays of the IFP of cervical carcinomas should involve contrast agents with higher MW than Gd-DTPA.

    We evaluated the diagnostic performance of FDG-PET for the detection of metastatic cervical lymph nodes in recurrent papillary thyroid carcinoma patients with negative I-131 scan. All patients had total thyroidectomy and following I-131 ablation therapy. In the follow-up period, FDG-PET showed suspected cervical lymph nodes metastases and neck dissection was performed within 3 months after FDG-PET. It had shown for all patients the negative I-131 scan within 3 months before FDG-PET or negative I-131 scan during the period of cervical lymph nodes metastases suspected on the basis of FDG-PET, CT, or ultrasonography until the latest FDG-PET. Preoperative FDG-PET results were compared with the pathologic findings of lymph nodes specimens of 19 papillary thyroid carcinoma patients. Serum Tg, TSH, and Tg antibody levels at the time of latest I-131 scan were reviewed. The size of lymph node was measured by preoperative CT or ultrasonography. In 45 cervical lymph node groups dissected, 31 lymph node groups revealed metastasis. The sensitivity and specificity of FDG-PET for metastasis were 74.2% (23 of 31) and 50.0% (7 of 14), respectively. Except for patients with elevated Tg antibody levels, all patients showed the elevated serum Tg levels than normal limits at the TSH of =30uIU/ml. 8 lesions without suspected metastatic findings on FDG-PET revealed metastasis (false negative), and none of them exceeded 8mm in size (4 to 8mm, median= 6mm). On the other hand, 23 true positive lesions on FDG-PET were variable in size (6 to 17mm, median=9mm). FDG-PET is suitable for the detection of metastatic cervical lymph nodes in patients with recurrent papillary thyroid carcinoma. However, false positive or false negative should be considered according to the size of lymph node.

    Full Text Available Abstract Background High risk type human papilloma viruses (HR-HPV induce carcinomas of the uterine cervix by expressing viral oncogenes E6 and E7. Oncogene E7 of HR-HPV disrupts the pRb/E2F interaction, which negatively regulates the S phase entry. Expression of tumor suppressor p16ink4a drastically increases in majority of HR-HPV associated carcinomas due to removal of pRb repression. The p16ink4a overexpression is an indicator of an aberrant expression of viral oncogenes and may serve as a marker for early diagnostic of cervical cancer. On the other hand, in 25–57% of cervical carcinomas hypermethylation of the p16 INK4a promoter has been demonstrated using a methylation-specific PCR, MSP. To evaluate a potential usage of the p16 INK4a 5' CpG island hypermethylation as an indicator of tumor cell along with p16ink4a overexpression, we analyzed the methylation status of p16 INK4a in cervical carcinomas Methods Methylation status of p16 INK4a was analyzed by MSP and by bisulfite-modified DNA sequencing. The expression of p16ink4a was analyzed by RT-PCR and by immunohistochemical technique. Results The extensive methylation within p16 INK4a 5' CpG island was not detected either in 13 primary cervical carcinomas or in 5 cancer cell lines by bisulfite-modified DNA sequencing (including those that were positive by MSP in our hands. The number and distribution of rare partially methylated CpG sites did not differ considerably in tumors and adjacent normal tissues. The levels of the p16 INK4a mRNA were increased in carcinomas compared to the normal tissues independently of the number of partially methylated CpGs within 5'CpG island. The transcriptional activation of p16 INK4a was accompanied by p16ink4a cytoplasmic immunoreactivity in the majority of tumor cells and presence of a varied number of the p16 positive nuclei in different tumors. Conclusion Hypermethylaion of the p16INK4a 5' CpG island is not a frequent event in HR-HPV-positive cervical

    To evaluate the efficacy of radiofrequency ablation (RFA) in the treatment of loco-regional, recurrent, and well-differentiated thyroid carcinoma. Thirty-five recurrent well-differentiated thyroid carcinomas (RTC) in 32 patients were treated with RFA, between March 2008 and October 2011. RTCs were detected by regular follow-up ultrasound and confirmed by biopsy. All patients had fewer than 3 RTCs in the neck and were at high surgical risk or refused to undergo repeated surgery. Average number of RFA sessions were 1.3 (range 1-3). Post-RFA biopsy and ultrasound were performed. The mean follow-up period was 30 months. Pre- and post-RFA serum thyroglobulin values were evaluated. Thirty-one patients with 33 RTCs were treated with RFA only, whereas 1 patient with 2 RTCs was treated with RFA followed by surgery. At the last follow-up ultrasound, 31 (94%) of the 33 RTCs treated with RFA alone completely disappeared and the remaining 2 (6%) RTCs showed decreased volume. The largest diameter and volume of the 33 RTCs were markedly decreased by 93.2% (from 8.1 +/- 3.4 mm to 0.6 +/- 1.8 mm, p < 0.001) and 96.4% (from 173.9 +/- 198.7 mm{sup 3} to 6.2 +/- 27.9 mm{sup 3}, p < 0.001), respectively. Twenty of the 21 RTCs evaluated with post-RFA biopsies (95%) were negative for malignancy. One (5%) showed remaining tumor that was removed surgically. The serum thyroglobulin was decreased in 19 of 26 patients (73%). Voice change developed immediately after RFA in 6 patients (19%) and was spontaneously recovered in 5 patients (83%). Radiofrequency ablation can be effective in treating loco-regional, recurrent, and well-differentiated thyroid carcinoma in patients at high surgical risk.

    A 32 year Libyan male presented with the complaints of headache and diplopia. He was diagnosed with a cavernous sinus meningioma on the basis of MRI findings but no initial biopsy was taken. Depending on the radiologic diagnosis the patient was treated with gamma knife surgery twice, abroad. During follow up he developed left ear deafness and left cervical lymph adenopathy. An ENT evaluation with biopsy from the nasopharynx and cervical lymph node was taken. The histopathologic diagnosis of the resected tumour showed a nasopharyngeal carcinoma with cervical lymph node metastasis (poorly differentiated lympho-epithelial carcinoma). The cavernous sinus tumour which was initially treated as a meningioma was in fact metastasis from the nasopharyngeal carcinoma, making this an interesting and rare occurrence.

    The majority of penile carcinoma is squamous cell carcinoma. Although uncommon in the United States, it represents a larger proportion of cancers in the underdeveloped world. Invasive squamous cell carcinoma may arise from precursor lesions or de novo , and has been associated with lack of circumcision and HPV infection. Early diagnosis is imperative as lymphatic spread is associated with a poor prognosis. Radical surgical treatment is no longer the mainstay, and penile sparing treatments now are often used, including Mohs micrographic surgery. Therapeutic decisions should be made with regard to the size and location of the tumor, as well as the functional desires of the patient. It is critical for the dermatologist to be familiar with the evaluation, grading/staging, and treatment advances of penile squamous cell carcinoma. Herein, we present a review of the literature regarding penile squamous cell carcinoma, as well as a case report of invasive squamous cell carcinoma treated with Mohs micrographic surgery.

    Introduction: The objective of this trial is to investigate the diagnostic value of magnetic resonance imaging (MRI) with an endorectal surface coil for precise local staging of patients with histologically proven cervical cancer by comparing the radiological, clinical, and histological results. Materials and methods: Women with cervical cancer were recruited for this trial between February 2007, and September 2010. All the patients were clinically staged according to the FIGO classification and underwent radiological staging by MRI that employed an endorectal surface coil. The staging results after surgery were compared to histopathology in all the operable patients. Results: A total of 74 consecutive patients were included in the trial. Forty-four (59.5%) patients underwent primary surgery, whereas 30 (40.5%) patients were inoperable according to FIGO and underwent primary radiochemotherapy. The mean age of the patients was 50.6 years. In 11 out of the 44 patients concordant staging results were obtained by all three staging modalities. Thirty-two of the 44 patients were concordantly staged by FIGO and histopathological examination, while only 16 were concordantly staged by eMRI and histopathological examination. eMRI overstaged tumors in 14 cases and understaged them in 7 cases. Conclusions: eMRI is applicable in patients with cervical cancer, yet of no benefit than staging with FIGO or standard pelvic MRI. The most precise preoperative staging procedure still appears to be the clinical examination.

    The purpose of this study was to correlate the pattern of tumor extent of nasopharyngeal carcinoma at the primary site on magnetic resonance (MR) imaging with the distribution of cervical lymph node metastasis. MR images of 32 patients with biopsy-proven nasopharyngeal carcinoma were reviewed and classified into five patterns of tumor extent in correlation with the distribution of cervical lymphadenopathy. The assessment of cervical lymph node metastasis was done on the basis of the computed tomography (CT) findings. The tumor volume was also correlated with the occurrence of contralateral lymphadenopathy. Of the 32 patients, five (16 %) presented as type 1, tumor limited to the nasopharyngeal mucosa; 12 (38 %) as type 2 a, tumor which had invaded either lateral side but did not extend over the roof of nasopharynx; three (9 %) as type 2 b, tumor which had invaded bilaterally across the midline but did not extend over the roof of nasopharynx; three (9 %) as type 2 c, tumor which had invaded mainly the skull base but did not cross the midline; and nine (28 %) as type 3, tumor which had extended anteriorly to the nasal cavity without invasion. Twenty-five patients (78 %) demonstrated cervical lymphadenopathy. Patients with type 1, type 2 b and type 3 spread had frequent bilateral cervical lymphadenopathy; those with type 2 a had only ipsilateral lymphadenopathy. There was statistical significance (P < 0.005) regarding the existence of contralateral lymphadenopathy with midline tumors as well as the absence of contralateral cervical lymphadenopathy with non-midline tumors. This study therefore suggests that the distribution of metastasized lymph nodes depends on the pattern of tumor extent at the primary site. (orig.)

    Full Text Available Sebaceous carcinoma is a rare malignancy of the skin appendages. It tends to occur in elderly patients. Orbital region is the most commonly involved site seen in 75% of cases. The involvement of extra-orbital sites is infrequent. Herein, a case of extra-ocular sebaceous carcinoma arising in the scalp of a 20-year-old man is described.The patient developed tumor relapse after excision biopsy. He was treated with wide local excision of the tumor. However, the patient developed local recurrence after an interval of four months for which he again underwent wide local excision. He did not manifest any regional or distant metastases. In view of the locally aggressive tumor, he received adjuvant radiation therapy. The patient was successfully treated with no evidence of any local recurrence seen after a follow-up period of one year. The timely recognition of sebaceous carcinoma is imperative so as to execute the primary treatment i.e., wide local excision. Adjuvant radiotherapy may be considered to improve the clinical outcome for recurrent tumors.

    Full Text Available We present the case of a 40-year-old man with previously treated thymic carcinoma, complaining of gradually worsening back pain. Computed tomography scans of the chest showed multiple pleural disseminated nodules with a pleural effusion in the right thorax. The patient was treated with carboplatin on day 1 plus nab-paclitaxel on day 1 and 8 in cycles repeated every 4 weeks. Objective tumor shrinkage was observed after 4 cycles of this regimen. In addition, the elevated serum cytokeratin 19 fragment level decreased, and the patient's back pain was relieved without any analgesics. Although he experienced grade 4 neutropenia and granulocyte colony-stimulating factor (G-CSF injection, the severity of thrombocytopenia and nonhematological toxicities such as reversible neuropathy did not exceed grade 1 during the treatment. To our knowledge, this is the first report to demonstrate the efficacy of combination chemotherapy consisting of carboplatin and nab-paclitaxel against thymic carcinoma. This case report suggests that nab-paclitaxel in combination with carboplatin can be a favorable chemotherapy regimen for advanced thymic carcinoma.

    Cervical surgery is associated with preterm birth (PTB) and neonatal morbidity. However, it is unknown whether this increased risk is due to the surgery itself or to the cervical intraepithelial neoplasia (CIN) underlying the surgery. Our objective was to assess the risk for PTB in women with treated and untreated CIN. We performed an electronic literature search in MEDLINE, Embase and CENTRAL for studies that reported on pregnancy outcome after treated and untreated CIN. The methodological quality was scored using the STROBE combined checklist for observational studies. We extracted data on PTBtreatment for CIN. We used the Mantel-Haenszel method to estimate summarizing odds ratios. Our search identified 620 studies, of which 20 were reporting on pregnancy outcome for a total of 12,159,293 women. There were 20,832 women who gave birth after treatment for CIN before pregnancy, 52 women who gave birth after treatment for CIN during pregnancy, 64,237 women with CIN who gave birth before treatment, and 8,902,865 women who gave birth without CIN. Compared to women with untreated CIN, women treated for CIN before or during pregnancy, had a significantly higher risk of PTBCIN before pregnancy (n=20,832) to women with untreated CIN (n=64,162), we found an OR of 1.4 with a 95% confidence interval of 0.85-2.3. Women treated during pregnancy had a clearly increased risk for PTB (OR 6.5, 95% CI 1.1-37), and (P)PROM (OR 1.8, 95% CI 1.4-2.2). In women with cervical surgery, the risks for spontaneous PTBCIN is especially increased when performed during pregnancy. When performed before pregnancy the risk of PTB is increased, although insignificant. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Selective dorsal rhizotomy is an effective method to reduce spasticity of the lower limbs. However, functional outcomes in the upper limb following selective dorsal rhizotomy at the cervical level have not been reported. Here we report the clinical course after selective dorsal rhizotomy at the cervical level in a patient with hemiplegic spasticity caused by brain injury. The selective dorsal rootlets at the cervical level were sectioned under electrophysiological monitoring. The patient was followed for 1 year to evaluate the outcome of surgery. The spasticity in the upper limb was reduced and the passive range of motion and function of movement improved. However, the effectiveness and the safety of operation should be studied further in clinical trials.

    Chordomas are malignant tumors arising from notochordal remnants. They are the most frequent tumors of the spine after plasmacytomas. Only 6% of chordomas are localized to the cervical level. In young patients, chordomas are rare and unpredictable. Despite this, the treatment of choice remains the total resection, as much as possible, followed by proton beam radiation. This case was managed using a precarotid and retrocarotid approach at the same time. The tumor was completely resected with the edges free from disease. The cervical spine was stabilized with an anterior plating C2-C4. Eighteen months after surgery the patient is still free from illness. Multilevel oblique corpectomies are an available and safe option for the treatment of upper cervical chordomas.

    The prognosis of locally advanced cervix cancers is poor with metastatic and local recurrence risks. Recent publications reported that concurrent chemotherapy and pelvic radiation increased local control compared to radiotherapy alone. Chemotherapy could also decrease metastatic recurrences. We report 92 cases of patients with locally advanced cervix cancer treated between 1986 and 1998 at the Institut Curie. Patients and methods. - Concurrent chemo-radiation was exclusive in 51 cases and added to surgery in 41 cases. Chemotherapy with 5FU -Cisplatin-Mitomycin C-Vindesin (protocol A) was performed for 43% of patients and 57% of them received 5FU-Cisplatin alone (protocol B). Results. -Median follow-up was 64 months (6-149 months). Five-year disease-free survival rate was 47% and local control rate was 70%. Disease-free survival was correlated with therapeutic response. After exclusive chemo-radiation, the good responsive patients had a better DFS (54% vs 26%, p=0.018). In the surgery group, those patients with sterilized lymph nodes and tumours had also a higher DFS (76% vs 47%, p=0.036). Toxicity was higher with protocol A. Conclusion. - From our study, it appears that local control of advanced cervix cancers is better with combined chemoradiotherapy but disease-free survival stays low according to the metastatic evolution. Metastasis without local recurrence remained frequent in our study. 5FU-CDDP chemotherapy has a lower toxicity and is as effective as 5FU-CDDP-Mitomycin C-Vindesin protocol, in association with radiotherapy.

    We wanted to determine the utility of CT enhancement for diagnosing metastatic lymphadenopathy in patients with papillary thyroid carcinoma (PTC), and especially in the lymph nodes (LNs) of the lateral neck level and that are not suspicious for metastasis on ultrasonography (US). Our study population included 34 consecutive LNs of 31 patients (25 females and 6 males, mean age: 46.7 yrs) with PTC and who had no suspicious metastatic lateral cervical LN on preoperative US, but enhancement of the lateral cervical LNs was seen on CT. To objectify the degree of enhancement, the difference of Hounsfield units between the suspicious LN and that of the ipsilateral SCM muscle was calculated. For the node-by-node analysis, marking of the corresponding LN with CT enhancement on the second look US was performed. The final assessment was attained by surgical dissection of the marked LNs. The medical records were reviewed for the patients' age and gender and the size of the LNs. Among the 34 LNs, 17 LNs were diagnosed as metastasis and 17 were benign. There was no difference in the size of the LNs between two the groups (benign and metastatic). The patients who had metastatic LNs were younger than those patients with benign LNs (p = 0.037). The incidence of metastatic LN was higher in the male patients than in the female patients (F:M = 38.5%:100%, p = 0.018). There was no statistical difference between the metastatic LNs and benign LNs according to the degree of enhancement (p = 0.953). The degree of CT enhancement is not feasible to use for diagnosing metastatic LNs in the lateral neck level in patients with PTC

    Full Text Available Abstract Background Secondary radiation-induced cancers are rare but well-documented as long-term side effects of radiation in large populations of breast cancer survivors. Multiple neoplasms are rare. We report a case of esophageal adenocarcinoma in a patient treated previously for breast cancer and clear cell carcinoma of the kidney. Case presentation A 56 year-old non smoking woman, with no alcohol intake and no familial history of cancer; followed in the National Institute of Oncology of Rabat Morocco since 1999 for breast carcinoma, presented on consultation on January 2011 with dysphagia. Breast cancer was treated with modified radical mastectomy, 6 courses of chemotherapy based on CMF regimen and radiotherapy to breast, inner mammary chain and to pelvis as castration. Less than a year later, a renal right mass was discovered incidentally. Enlarged nephrectomy realized and showed renal cell carcinoma. A local and metastatic breast cancer recurrence occurred in 2007. Patient had 2 lines of chemotherapy and 2 lines of hormonotherapy with Letrozole and Tamoxifen assuring a stable disease. On January 2011, the patient presented dysphagia. Oesogastric endoscopy showed middle esophagus stenosing mass. Biopsy revealed adenocarcinoma. No evidence of metastasis was noticed on computed tomography and breast disease was controlled. Palliative brachytherapy to esophagus was delivered. Patient presented dysphagia due to progressive disease 4 months later. Jejunostomy was proposed but the patient refused any treatment. She died on July 2011. Conclusion We present here a multiple neoplasm in a patient with no known family history of cancers. Esophageal carcinoma is most likely induced by radiation. However the presence of a third malignancy suggests the presence of genetic disorders.

    Aim The study was made to evaluate early and late toxicity in a diversified group of patients receiving definitive or adjuvant radiotherapy in terms of clinical diagnosis and treatment methods. Background Radiotherapy is a standard way of treatment in cervical and endometrial cancer patients, both as definitive and adjuvant therapy. But every radiation treatment may be involved with toxicity. Materials and methods A detailed analysis was performed of 263 patients with gynaecological cancer treated with definitive (90 patients with cervical cancer received radiochemotherapy or radiotherapy exclusively) and adjuvant radiotherapy (38 with cervical and 135 with endometrial cancer). Results Acute reactions were found in 51.3% and late reactions were found in 14.8% of patients. It was stated that early (p radiotherapy. The analysis of the whole group revealed higher rate of toxicity, both early and late, in the gastrointestinal tract than in the urinary system (p radiotherapy group than in the adjuvant one. The occurrence of side effects was associated with the prolongation of total irradiation time due to necessary interruptions of radiotherapy. The comparison of the subgroups showed that interruptions occurred more frequently in patients receiving definitive rather than adjuvant radiotherapy (17.7–2.9%). Conclusions Definitive radiotherapy compared with adjuvant treatment may by associated with higher percentage of side effects caused by dose of therapy and correlation with chemotherapy.

    Modern multidisciplinary cancer treatments aim at obtaining minimal influence on patients' quality of life (QoL). The purpose of this study was to assess QoL and correlate it with dose-volume parameters of organ at risks (OARs) in patients who received adjuvant radiotherapy for endometrial and cervical cancers. We administered the EORTC QLQ-C30 and EN24 or CX24 questionnaires to 124 patients, 100 with endometrial cancer and 24 with cervical cancer treated with postoperative radiotherapy ± chemotherapy in regular follow-up. Bladder function, fecal incontinence or urgency and sexual functioning were investigated and correlated with dose-volume parameters of OAR by multiple linear regression analysis. This correlation was assessed by R (2) value. QoL was very high in the majority of patients (82.3 % of patients). Few patients referred urinary incontinence (3.2 %) or abdominal discomfort of high grade (4.0 %). We found a significant correlation between bladder V40, i.e., absolute percentage of bladder volume that received a dose of 40 Gy, and global health status (p radiotherapy for endometrial and cervical cancers have good QoL with minimal limitations of daily activities. QoL was correlated with dose-volume parameters such as bladder V40, mean dose to vagina, maximum dose to trigone and LSP.

    Full Text Available Cervical erosion, a pathological change associated with chronic cervicitis, is a common condition that is difficult to cure. Many patients particularly those with mild or medium infection and those preparing for pregnancy require a simple but effective medication. In this study, extracts of an empirical herbal prescription composed of six Chinese traditional drugs viz Cortex Phellodendri, Rhizoma Coptidis, Olibanum, Myrrha, borneol and catechu were formulated to facilitate intravaginal administration and improve efficacy. An extract of the first four components was formulated with borneol as a thermosensitive gel (TG while an extract of catechu used to prepare a regular gel (CG because of a chemical incompatibility. The optimized TG was prepared using poloxamer 407 and poloxamer 188. The CG was prepared using glycerin, carbopol and triethanolamine. The gels were characterized in vitro in terms of release of berberine (TG and total catechins (CG and in vivo in a rat model of cervical erosion. Treatment by once daily application of the TG for 7 days followed by once daily application of the CG for 3 days produced a restoration of normal tissues. Gel formulation of the empirical Chinese traditional remedy appears to provide a promising treatment for cervical erosion.

    The impact of cervical lymph node metastases and the optimal surgical management of the neck in patients with papillary thyroid carcinoma (PTC) remain controversial. The objectives of this retrospective study were to determine, in patients with PTC, the predictive factors and the impact on tumor recurrence rate of cervical lymph node involvement, and to evaluate the oncologic results and the morbidity of central neck dissection (CND). We reviewed the records of patients who had undergone surgical treatment for PTC at our institution between 1990 and 2000. A total of 368 patients (86 men and 282 women) were included in this study. Young age (p = 0.02), tumor size (p = 0.001) and extrathyroidal tumor extension (p = 0.003) were significant predictive factors of cervical lymph node metastatic involvement (multivariate analysis). Initial metastatic cervical lymph node involvement was identified as an independent risk factor of tumor recurrence (multivariate analysis, p = 0.01). Metastatic lymph node(s) were found in prophylactic CND specimens in 31% of the patients. CND increased the risk of postoperative hypocalcemia (p = 0.008) and of permanent hypoparathyroidism (p = 0.002). In conclusion, cervical lymph node metastatic involvement at the time of initial surgery is an independent risk factor of tumor recurrence. CND provided an up-staging of more than 30% of patients with a clinically N0 neck, but was associated with significant morbidity regarding parathyroid function.

    To analyze prognostic factors for locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) in cervical cancer patients who underwent radical hysterectomy followed by postoperative radiotherapy (PORT) in a single institute. Clinicopathologic data of 135 patients with clinical stage IA2 to IIA2 cervical cancer treated with PORT from 2001 to 2012 were reviewed, retrospectively. Postoperative parametrial resection margin (PRM) and vaginal resection margin (VRM) were investigated separately. The median treatment dosage of external beam radiotherapy (EBRT) to the whole pelvis was 50.4 Gy in 1.8 Gy/fraction. High-dose-rate vaginal brachytherapy after EBRT was given to patients with positive or close VRMs. Concurrent platinum-based chemoradiotherapy (CCRT) was administered to 73 patients with positive resection margin, lymph node (LN) metastasis, or direct extension of parametrium. Kaplan-Meier method and log-rank test were used for analyzing LRR, DM, and OS; Cox regression was applied to analyze prognostic factors. The 5-year disease-free survival was 79% and 5-year OS was 91%. In univariate analysis, positive or close PRM, LN metastasis, direct extension of parametrium, lymphovascular invasion, histology of adenocarcinoma, and chemotherapy were related with more DM and poor OS. In multivariate analysis, PRM and LN metastasis remained independent prognostic factors for OS. PORT after radical hysterectomy in uterine cervical cancer showed excellent OS in this study. Positive or close PRM after radical hysterectomy in uterine cervical cancer correlates with poor prognosis even with CCRT. Therefore, additional treatments to improve local control such as radiation boosting need to be considered.

    The buccal mucosa is the site with the highest risk of contracting a malignancy in habitual betel quid chewers who expose the buccal mucosa to high doses of carcinogens. Of all oral cancers, those of the buccal mucosa are associated with the poorest prognoses. Therefore, it would be helpful to have an animal model to evaluate new treatment modalities for buccal mucosa cancer. In the present study, we evaluated whether the imprinting control region (ICR) mouse animal model could be employed as a cancer model for buccal mucosa cancer. Sixty male ICR mice were randomly divided into two groups, a normal group (n=10) and a cancer-induced group (n=50). Each mouse in the cancer group was inoculated with 0.05 ml U14 cancer cell suspension (1×10(7)/ml) on the buccal mucosa. Histological staining and gene expression assays revealed that neck lymph node metastasis animal models were established. After 20 days, the cheek tumor formation rate of the ICR mice reached 100%. Furthermore, the neck lymph node metastasis rate was 53%. We identified that U14 cells produce strong metastasis in ICR mice. Metastasis of the tumor to the lymph node began with carcinoma metastasis encroaching on the marginal sinus. Then it infiltrated to the cortex and medulla and the infiltration continued until the normal lymph node structure was completely damaged. This animal model may be employed in medical research on buccal mucosa cancer and cervical lymph node metastasis. In conclusion, our findings indicate that U14 cell-induced mouse buccal mucosa cancer may be a potential cancer model for human buccal mucosa squamous cell carcinoma.

    OBJECTIVE To investigate the outcome and indications for radical nephrectomy with a Chevron incision to treat complicated renal carcinoma.METHODS Large renal carcinomas were found in 15 patients during a preoperative CT and/or MRI examination. A tumor thrombus in the renal vein or inferior vena cava was found in 5 cases, and a complication of metastasis in the contralateral adrenalgl and was found in 2 patients. All of the 15 patients underwent a radical nephrectomy by a chevron incision and the postoperative pathological results noted.RESULTS Of the 15 patients who underwent a radical nephrectomy and lymphadenectomy, 5 also received a thrombectomy, and 2 a contralateral adrenalectomy. All surgical operations were safe and successful. The mean operation time was (4.45±0.83) h, and the intraoperative blood loss was (785±910) ml. All patients recovered well after the surgery. Multimodal therapy was conducted in these cases, with rigorous follow-up.CONCLUSION In determining the type of incision for surgery of renal carcinoma, a chevron incision is suitable for cases with a large tumor, local nodal metastasis, thrombus of the renal vein or inferior vena cava and complicated metastasis to the contralateral adrenal gland. The incision produces a clear operating field with less intra- and post-operative complications.

    OBJECTIVE: To study the relationship between the expressions of Survivin and VEGF in cervical carcinoma and the clinical feature of cervical carcinoma, and to observe the correlation between Survivin and VEGF in cervical carcinoma. METHODS: Using streptavidin-biotin peroxidase (SP) method, the expressions of Survivin and VEGF were examined in 73 cases of cervical carcinoma, 25 cases of cervical intraepithelial neoplasia (CIN) and 20 cases of chronic cervicitis. RESULTS: Survivin and VEGF positive expression rate in cervical carcinoma group respectively were 75. 3% and 78. 1%, chronic cervical inflammation group were 5. 0% and 10. 0%, CIN group were 48. 0% and 52. 0%. The expression of Survivin and VEGF present a growing trend from chronic cervicitis to cervical carcinoma. The expression of Survivin and VEGF were related to the clinical stages and lymph node metastasis of cervical carcinoma. A positive correlation existed among Survivin and VEGF ( r = 0. 738, P<0. 01). CONCLUSION: The expressions of Survivin and VEGF in cervical carcinoma reflect the local invasion activity and metastasizing proficiency of cervical carcinoma, which are closely related to metastasis, clinical stages and prognosis of cervical carcinoma, and have synergistic effect in incidence and development of cervical carcinoma.%目的:探讨宫颈癌组织存活素(Survivin)与血管内皮生长因子(VEGF)的表达与宫颈癌临床特征的关系以及两者的相关性.方法:采用免疫组化SP法检测73例宫颈癌,25例宫颈上皮内瘤样病变(CIN)和20例慢性宫颈炎组织Survivin和VEGF的表达水平.结果:宫颈癌组织Survivin和VEGF阳性表达率分别为75.3%和78.1%,慢性宫颈炎组分别为5.0%和10.0%,CIN组分别为48.0%和52.0%.从慢性宫颈炎组到宫颈癌组,Survivin和VEGF表达率逐渐升高,P<0.05.Survivin和VEGF的表达与宫颈癌临床分期及淋巴结转移相关.Survivin表达与VEGF表达呈正相关,r=0.738,P<0.01.结论:Survivin

    Neuroendocrine cervical carcinoma is a rare subtype of cervical cancer. These tumors exhibit an aggressive behavior with early regional lymph node and distant metastases. The purpose of our study was to describe five cases of neuroendocrine cervical-vaginal carcinoma and to discuss the potential of the 2-[{sup 18}F] fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography ({sup 18}F-FDG PET/CT) scan for the detection of this rare malignancy. Five cases of cervical-vaginal neuroendocrine tumor were retrospectively collected, during a two year (from September 2009 to August 2011) period in our hospital. The clinical staging distributions were International Federation of Gynecology and Obstetrics (FIGO) stage IB2 (1 of 5), stage IIA (3 of 5) and stage IVA (1 of 5). Two cases (cases 1 and 4) were restaged after {sup 18}F-FDG PET/CT scan in the initial staging process. Post-treatment {sup 18}F-FDG PET/CT scans, in three patients, revealed positive findings for tumor recurrence or lymph node metastases. Two patients (cases 2 and 3) died of tumor within two years. {sup 18}F-FDG PET/CT scan is a useful tool in cervical-vaginal neuroendocrine tumor. In its initial staging, the {sup 18}F-FDG PET/CT scan may help assess the possible nodal involvement or early hematogeneous spreading. We can also use the {sup 18}F-FDG PET/CT to detect local recurrence and to evaluate the treatment response after clinical manipulation.

    New N-1-sulfonylpyrimidines showed potent growth inhibitory activity against human and mouse tumour cells of different origin. 1-(p-toluenesulfonyl)cytosine (TsC) and 1-(p-toluenesulfonyl)cytosine hydrochloride (TsC × HCl) inhibited the growth of human cervical carcinoma cells (HeLa), and had no significant cytotoxic effects on normal human foreskin fibroblasts (BJ). TsC and TsC × HCl interfered with the HeLa cell cycle progression bringing about the accumulation of G1 phase cells and the induction of apoptosis. Antiproliferative effects of TsC and TsC × HCl were additionally confirmed by investigating de novo synthesis of RNA, DNA and proteins in HeLa cells. Monitoring gene expression using DNA Chip Analysis and quantitative PCR showed that TsC × HCl affects the expression of several cell-cycle regulating genes implying that cell cycle arrest and DNA damage-induced apoptosis might account for the observed cellular effects. In vivo experiments revealed low toxicity of TsC × HCl, as demonstrated by unaltered haematological and metabolic blood parameters. In conclusion, potent antitumour efficacy and low toxicity of new compounds in comparison with the common chemotherapy drug 5-FU make them promising anticancer agents. Additional pre-clinical and clinical studies are warranted to illuminate the mode of action of these newly synthesized compounds in vivo, which would lay the groundwork for their further optimization.

    Full Text Available Flavonoids are phytochemicals characterized by a wide range of biological activities, including antioxidant activity, the ability to modulate enzyme or cell receptor activity patterns, and to interfere with essential biochemical pathways. Using HeLa cells of a human cervical carcinoma, and their drug-resistant HeLa CK subline, the effects of three structurally related flavonoids (quercetin, fisetin and luteolin have been examined, in terms of their: (i cytotoxicity, (ii influence on intracellular glutathione (GSH level, (iii influence on glutathione S-transferase (GST activity, and (iv influence on the expression of apoptosis-related genes (PARP, Bcl-2, survivin. Fisetin was more toxic to resistant HeLa CK cell line than to parental cell line, causing decreased expression of survivin in the same cell line. Concentrations of 5 μM of the examined flavonoids caused PARP degradation in parental cell line, leading HeLa cell line into apoptotic cell death. The same event was not determined in the resistant cell line. Fisetin and luteolin induce glutathione and GST in the resistant cell line, pointing to complex cellular effects which could be responsible for higher sensitivity of the resistant cell line in comparison with the parental cell line. Prooxidative nature of the investigated flavonoids was not detected, so free radical formation is not responsible for the induction of GSH, GST and proapoptotic enzymes.

    Apoptin is a chicken anemia virus-derived,p53-independent,bcl-2-insensitive apoptotic protein with the ability to specifically induce apoptosis of various human tumor cells,but not of normal diploid cells.To explore the application of apoptin in tumor gene therapy,we used a recombinant fowlpox virus expressing apoptin protein (vFV-Apoptin) to investigate the anti-tumor effectes of vFV-Apoptin on human cervical carcinoma(HeLa) cells in vivo and in vitro through 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide(MTT) assay,acridine orage/ethidium bromide(AO/EB) and annexin V staining test,respectively.The results show that vFV-Apoptin inhibites the proliferation of HeLa cells in vitro through inducing the apoptosis of HeLa cells,and the inhibition effect of vFV-Apoptin has a dose-effect and time-effect relationship.The results of animal models show that vFV-Apoptin significantly inhibits tumor growth,extends the lifespan of animals and improves the mean survival.Experimental results indicate that vFV-Apoptin has a potential application in the tumor gene therapy.

    Late-phase complications of the intestinal and the urinary tracts due to radiation therapy are very difficult to manage, and ensuing fistulation sometimes necessitates surgrey. We report excellent surgical results for a fistula incuded by radiation therapy in a 61-years-old woman. There were previous histories of receiving combined surgical and radiation (up to 10,000 rad) therapy for a uterine cervical carcinoma at another hospital in 1990, and undergoing several surgical treatments for the consequenct vesico-enteral and vesico-colic fistulas. In January, 1993, the patient was admitted to the department of urology of this hospital because of an abdominal pain, and was transferred to the department under a diagnosis of entero-cutaneous and vesico-enteral fistulas. After local sump suction and skin care, resection of the fistula and involved small intestine conserving the urinary tract was performed, and the omentum was transferred to the resected space. Cholecystectomy was carried out for cholelithiasis. Histological studies revealed atrophy in the mucosal layer and edema in the submucosal layer. Her postoperative course has been satisfactory without any signs of fistulation as of one year after the operation. (author).

    Materials and Methods: Twenty two patients of post irradiated recurrent cervical carcinoma (PIRCC were enrolled in this prospective study. 18-fluorodeoxyglucose (FDG PET imaging was performed in each patient before the salvage therapy. The maximum standardized uptake value (SUVmax and metabolic tumor volume (MTV were measured and correlated with cumulative progression free survival (PFS. Results: Median age of patients was 42 years. Majority of patients had stage III disease at the initial presentation and all 22 patients had received prior definitive RT. The median recurrence free period was 11 months. Salvage therapy consisted of surgical resection or re-irradiation depending upon the various clinical and radiological factors. Median SUVmax was 5.8 (range 1.8-50.6 and median MTV was 43 cm 3 (range 5.8-243. The cumulative PFS for all patients was 20% at 30 months. The one-year PFS was 28% for patients with SUVmax value of >5.8 versus 42% for those with SUVmax value of 43 cm 3 versus 45% for those with MTV value of <43 cm 3 (P value 0.8. Conclusion: Our preliminary experience has suggested that FDG uptake on PET scan can predict the clinical outcome of PIRCC patients. Further randomized studies may be conducted with large sample size and longer follow up to establish its definite predictive value.

    Purpose: To investigate the value of diffusion-weighted MR imaging (DWI) in detection of cervical cancer, and to determine the diagnostic accuracy of apparent diffusion coefficient (ADC) values for evaluating cervical cancer before and after chemoradiotherapy. Materials and methods: Thirty-three patients with cervical squamous carcinoma and 20 patients with other pelvic abnormalities underwent diffusion-weighted imaging (DWI) in addition to routine MR imaging. The ADC values of normal cervical tissue, cervical area before and after chemoradiotherapy were measured and compared. Receiver operating characteristic (ROC) analysis was employed to investigate whether ADC values could help in discrimination among normal cervical tissue, cervical cancer before and after therapy, and to obtain the optimal ADC threshold value. Results: Cervical cancer lesion demonstrated obviously hyperintensity on DWI images. The mean ADC value of cervical carcinoma (1.110 {+-} 0.175 x 10{sup -3} mm{sup 2}/s) was significantly lower than that of normal cervical tissue (1.593 {+-} 0.151 x 10{sup -3} mm{sup 2}/s) (P < 0.001). The mean ADC value of the cervical area in 22 patients treated by chemoradiotherapy (1.436 {+-} 0.129 x 10{sup -3} mm{sup 2}/s) was significantly higher than that before therapy (1.013 {+-} 0.094 x 10{sup -3} mm{sup 2}/s) (P < 0.001). The difference of ADC values between normal cervical tissue and cervical area after therapy was statistically significant (P < 0.01). The optimal ADC threshold values for distinguishing between normal cervical tissue and cervical carcinoma was 1.359 x 10{sup -3} mm{sup 2}/s, between cervical area before and after therapy was 1.255 x 10{sup -3} mm{sup 2}/s, between normal cervical tissue and cervical area after therapy was 1.525 x 10{sup -3} mm{sup 2}/s. The sensitivity and specificity were 100% and 84.8%, 95.5% and 100%, 70% and 81.8%, respectively. Conclusion: DWI can be applied for the detection of cervical cancer because of its superior

    To investigate the predictors of distant relapse in International Federation of Gynecology and Obstetrics (FIGO) stage IIB-IVA cervical cancer patients treated with definitive radiotherapy (RT). The clinical data of 219 patients with FIGO stage IIB-IVA cervical cancer treated with definitive RT between January 1997 and December 2011 were retrospectively reviewed. The cumulative distant relapse, progression-free survival (PFS) and overall survival (OS) rates were calculated using the Kaplan-Meier method and compared using the log-rank test. A Cox proportional hazards regression model was used to investigate the predictors of distant relapse in patients. Following treatment with definitive RT, 61 of the 219 (27.9%) patients developed distant relapse with median PFS and OS rates of 9.9 and 32.8 months, and estimated five-year PFS and OS rates of 4.9% and 21.3%, respectively. Multivariate analysis revealed that pelvic node metastasis, pretreatment leukocytosis and pretreatment neutrophilia were significant predictors of distant relapse. The risk of developing distant relapse was found to be associated with the number of predictors that the patients displayed: the estimated five-year distant relapse rates of the patients with no predictors, one predictor and two predictors were 20.3%, 35.5% and 88.9%, respectively. Roughly 28% of patients with FIGO stage IIB-IVA cervical cancer developed distant relapse after definitive RT. Pelvic lymph node metastasis and pretreatment leukocytosis/neutrophilia are independent predictors of distant relapse. © 2017 Japan Society of Obstetrics and Gynecology.

    Full Text Available Although the possibility of developing cardiac steroids/cardiac glycosides as novel cancer therapeutic agents has been recognized, the mechanism of their anticancer activity is still not clear enough. Toad venom extract containing bufadienolides, which belong to cardiac steroids, has actually long been used as traditional Chinese medicine in clinic for cancer therapy in China. The cytotoxicity of arenobufagin, a bufadienolide isolated from toad venom, on human cervical carcinoma HeLa cells was checked. And, the protein expression profile of control HeLa cells and HeLa cells treated with arenobufagin for 48 h was analyzed using two-dimensional electrophoresis, respectively. Differently expressed proteins in HeLa cells treated with arenobufagin were identified and the pathways related to these proteins were mapped from KEGG database. Computational molecular docking was performed to verify the binding of arenobufagin and Na, K-ATPase. The effects of arenobufagin on Na, K-ATPase activity and proteasome activity of HeLa cells were checked. The protein-protein interaction network between Na, K-ATPase and proteasome was constructed and the expression of possible intermediate proteins ataxin-1 and translationally-controlled tumor protein in HeLa cells treated with arenobufagin was then checked. Arenobufagin induced apoptosis and G2/M cell cycle arrest in HeLa cells. The cytotoxic effect of arenobufagin was associated with 25 differently expressed proteins including proteasome-related proteins, calcium ion binding-related proteins, oxidative stress-related proteins, metabolism-related enzymes and others. The results of computational molecular docking revealed that arenobufagin was bound in the cavity formed by the transmembrane alpha subunits of Na, K-ATPase, which blocked the pathway of extracellular Na+/K+ cation exchange and inhibited the function of ion exchange.

    Suberonylanilide hydroxamic acid (SAHA) is an orally administered histone deacetylase inhibitor (HDACI) that has shown significant antitumour activity in a variety of tumour cells. To identify proteins involved in its antitumour activity, we utilized a proteomic approach to reveal protein expression changes in the human cervical cancer cell line HeLa following SAHA treatment. Protein expression profiles were analysed by 2-dimensional polyacrylamide gel electrophoresis (2-DE) and protein identification was performed on a MALDI-Q-TOF MS/MS instrument. As a result, a total of nine differentially expressed proteins were visualized by 2-DE and Coomassie brilliant blue (CBB) staining. Further, all the changed proteins were positively identified via mass spectrometry (MS)/MS analysis. Of these, PGAM1 was significantly downregulated in HeLa cells after treatment with SAHA. Moreover, PGAM1 has been proven to be downregulated in another cervical cancer cell line (CaSki) by western blot analysis. Together, using proteomic tools, we identified several differentially expressed proteins that underwent SAHA-induced apoptosis. These changed proteins may provide some clues to a better understanding of the molecular mechanisms underlying SAHA-induced apoptosis in cervical cancer.

    Determining the risk factors associated with parametrial involvement (PMI) is of paramount importance to decrease the multimodality treatment in early-stage cervical cancer. We investigated the preoperatively assessable clinical and pathological risk factors associated with PMI in surgically treated stage IB1-IIA2 cervical cancer. A retrospective cohort study of women underwent Querleu-Morrow type C hysterectomy for cervical cancer stage IB1-IIA2 from 2001 to 2015. All patients underwent clinical staging examination under anesthesia by the same gynecological oncologists during the study period. Evaluated variables were age, menopausal status, body mass index, smoking status, FIGO (International Federation of Obstetrics and Gynecology) stage, clinically measured maximal tumor diameter, clinical presentation (exophytic or endophytic tumor), histological type, tumor grade, lymphovascular space invasion, clinical and pathological vaginal invasion, and uterine body involvement. Endophytic clinical presentation was defined for ulcerative tumors and barrel-shaped morphology. Two-dimensional transvaginal ultrasonography was used to measure tumor dimensions. Of 127 eligible women, 37 (29.1%) had PMI. On univariate analysis, endophytic clinical presentation (P = 0.01), larger tumor size (P PMI. In multivariate analysis endophytic clinical presentation (odds ratio, 11.34; 95% confidence interval, 1.34-95.85; P = 0.02) and larger tumor size (odds ratio, 32.31; 95% confidence interval, 2.46-423.83; P = 0.008) were the independent risk factors for PMI. Threshold of 31 mm in tumor size predicted PMI with 71% sensitivity and 75% specificity. We identified 18 patients with tumor size of more than 30 mm and endophytic presentation; 14 (77.7%) of these had PMI. Endophytic clinical presentation and larger clinical tumor size (>3 cm) are independent risk factors for PMI in stage IB-IIA cervical cancer. Approximately 78% of the patients with a tumor size of more than 3 cm and endophytic

    Full Text Available The association of human papilloma virus (HPV infection and cervical intraepithelial neoplasia (CIN is well known. Interaction of HPV proteins with cellular regulatory proteins leads to up regulation of p16INK4A. The aim of this study was to evaluate p16INK4A protein as a biomarker for CIN lesions and squamous cell carcinoma on biopsy specimens of patients who underwent biopsy of the uterine cervix due to abnormal cytological finding.The authors analyzed biopsies from 50 patients with CIN and invasive squamous cell carcinoma of the uterine cervix. Expression of p16INK4A in CIN and invasive squamous cell carcinoma was immunohistochemically analyzed by using monoclonal anti-p16INK4A antibody.A total of 50 patients with CIN and invasive squamous cell carcinoma of the uterine cervix (mean age 40.2±11.5 years, range 20-74 years were analyzed. CIN I lesions were found in 27 (54%, CIN II/CIN III lesions in 9 (18%, and invasive squamous cell carcinoma in 14 (28% patients. Differences in the expression of p16INK4A between CIN I, CIN II/CIN III and squamous cell carcinoma were statistically significant (p<0.0001. Expression of p16INK4A showed low sensitivity (7%, specificity (8%, positive predictive value (8%, and negative predictive value (7% for CIN I. Sensitivity, specificity, positive predictive value, and negative predictive value of p16INK4A were 78%, 61%, 30%, and 93% for CIN II/CIN III, and 100%, 75%, 61%, and 100% for squamous cell carcinoma, respectively.Results of this study suggest that p16INK4A protein may be a sensitive biomarker for CIN II/CIN III lesions and invasive squamous cell carcinoma of the uterine cervix.

    Full Text Available Background: Mast cells are involved in induction of angiogenesis in the early-stages of tumor development and in modulating blood vessel growth in the later stages of tumor progression. Aims and Objectives: This study was carried out to evaluate the association between mast cell density (MCD and microvessel density (MVD in carcinoma in situ (CIS, microinvasive carcinoma (CA and invasive squamous cell CA of cervix. Materials and Methods: Six cases of CIS, four cases of microinvasive CA and 38 cases of invasive CA were studied over a period of 2 years from August, 2011 to June, 2013. Ten control samples were included in the study. Routine histologic examination was done. Toluidine blue stain was used for MCD determination. Immunohistochemical analysis with CD-34 was done for assessing MVD. Student′s t-test was used to calculate the statistical significance of MCD and MVD. Results: Both MCD and MVD increased from normal samples through CIS to invasive cervical CA. In the four cases of microinvasive CA, the MCD and MVD were more than that of the control samples, but less than that of the six cases of CIS. Conclusion: There is a correlation between mast cell accumulation and angiogenesis in CIS, microinvasive CA and invasive cervical squamous cell CA. MCD and MVD in invasive CA exceed those in CIS and microinvasive CA. It gives us an opportunity to postulate that therapeutic strategies against mast cell mediators and angiogenesis may be of benefit in patients of early-stage cervical CA.

    Purpose: To evaluate intensity modulated proton therapy (IMPT) in patients with cervical cancer in terms of coverage, conformity, and dose–volume histogram (DVH) parameters correlated with recommendations from magnetic resonance imaging (MRI)-guided brachytherapy. Methods and Materials: Eleven patients with histologically proven cervical cancer underwent primary chemoradiation for the pelvic lymph nodes, the uterus, the cervix, and the parametric region, with a symmetric margin of 1 cm. The prescription was for 50.4 Gy, with 1.8 Gy per fraction. The prescribed dose to the parametria was 2.12 Gy up to 59.36 Gy in 28 fractions as a simultaneous boost. For several reasons, the patients were unable to undergo brachytherapy. As an alternative, IMPT was planned with 5 fractions of 6 Gy to the cervix, including the macroscopic tumor with an MRI-guided target definition, with an isotropic margin of 5 mm for planning target volume (PTV) definition. Groupe-Europeen de Curietherapie and European society for Radiotherapy and Oncology (GEC-ESTRO) criteria were used for DVH evaluation. Reference comparison plans were optimized for volumetric modulated rapid arc (VMAT) therapy with the RapidArc (RA). Results: The dose to the high-risk volume was calculated with α/β = 10 with 89.6 Gy. For IMPT, the clinical target volume showed a mean dose of 38.2 ± 5.0 Gy (35.0 ±1.8 Gy for RA). The D{sub 98%} was 31.9 ± 2.6 Gy (RA: 30.8 ± 1.0 Gy). With regard to the organs at risk, the 2Gy Equivalent Dose (EQD2) (α/β = 3) to 2 cm{sup 3} of the rectal wall, sigmoid wall, and bladder wall was 62.2 ± 6.4 Gy, 57.8 ± 6.1 Gy, and 80.6 ± 8.7 Gy (for RA: 75.3 ± 6.1 Gy, 66.9 ± 6.9 Gy, and 89.0 ± 7.2 Gy, respectively). For the IMPT boost plans in combination with external beam radiation therapy, all DVH parameters correlated with <5% risk for grades 2 to 4 late gastrointestinal and genitourinary toxicity. Conclusion: In patients who are not eligible for brachytherapy, IMPT as a boost

    Cervical cancer is a common and an important public health problem for adult women in developing countries. In contrast, cervical cancer incidence is low in Saudi Arabia. High-risk types of human papilloma viruses (HPV16 and HPV18) are the most significant risk factors for cervical cancer. HPV16/18-E6 oncoprotein is associated with HPV etiology, viral persistence and epithelial transformation. Cell cycle protein p16 INK4a (p16) plays an important role in the pathophysiology of cervical carcinomas. The aims of this study were to investigate the expression of HPV16/18-E6 and p16 in uterine cervical carcinomas in Qassim Region--Saudi Arabia, and to relate the results to the established clinicopathological prognostic parameters (age of the patient, educational level, birth control methods, number of pregnancy, smoking status, degree of histological differentiation, clinical stage, and lymph node metastasis) The study included 40 specimens of uterine cervical squamous cell carcinomas diagnosed and confirmed by biopsy. Histopathological classification of cervical tumors cases was performed according to the International Federation of Gynecology and Obstetrics (FIGO). Immunohistochemical analysis for HPV16/18-E6 and p16 were carried out on formalin-fixed paraffin-embedded sections of cervical tissues using avidin-biotin peroxidase method. There was a significant statistical correlation between HPV16/18-E6 expression in cervical carcinoma and nationality, smoking status and size of the tumor. HPV16/18-E6 oncoprotein expression in normal lymphocytes and endothelial cells in the tumor tissues and the adjacent normal cervical tissues suggest the possibility that HPV infection might spread to other organs through blood circulation. P16 expression has been correlated with high grade, stage of cervical SCC and HPV16/18-E6 expression. The current study supports the critical function of p16 and HPV16/18-E6 as specific markers for cervical carcinoma. However the potential for usage

    Purpose: To compare rigosertib versus cisplatin as an effective radiosensitizing agent for cervical malignancies. Methods and Materials: Rigosertib and cisplatin were tested in cervical cancer cell lines, HeLa and C33A. A 24-hour incubation with rigosertib and cisplatin, before irradiation (2-8 Gy), was used for clonogenic survival assays. Cell cycle analysis (propidium iodide staining) and DNA damage (γ-H2AX expression) were evaluated by fluorescence-activated cell sorter cytometry. Rigosertib was also tested in vivo in tumor growth experiments on cervical cancer xenografts. Results: Rigosertib was demonstrated to induce a G{sub 2}/M block in cancer cells. Survival curve comparison revealed a dose modification factor, as index of radiosensitization effect, of 1.1-1.3 for cisplatin and 1.4-2.2 for rigosertib. With 6-Gy irradiation, an increase in DNA damage of 15%-25% was achieved in both HeLa and C33A cells with cisplatin pretreatment, and a 71-108% increase with rigosertib pretreatment. In vivo tumor growth studies demonstrated higher performance of rigosertib when compared with cisplatin, with 53% longer tumor growth delay. Conclusions: Rigosertib was more effective than cisplatin when combined with radiation and caused minimal toxicity. These data support the need for clinical trials with rigosertib in combination therapy for patients with cervical carcinoma.

    The efficacy of cancer treatments is often limited and associated with substantial toxicity. Appropriate combination of drug targeting specific mechanisms may regulate metabolism of tumor cells to reduce cancer cell growth and to improve survival. Therefore, we investigated the effects of anti-diabetic drug Metformin (Met) and a natural compound caffeic acid (trans-3,4-dihydroxycinnamic acid, CA) alone and in combination to treat an aggressive metastatic human cervical HTB-34 (ATCC CRL­1550) cancer cell line. CA at concentration of 100 µM, unlike Met at 10 mM, activated 5'-adenosine monophosphate-activated protein kinase (AMPK). What is more, CA contributed to the fueling of mitochondrial tricarboxylic acids (TCA) cycle with pyruvate by increasing Pyruvate Dehydrogenase Complex (PDH) activity, while Met promoted glucose catabolism to lactate. Met downregulated expression of enzymes of fatty acid de novo synthesis, such as ATP Citrate Lyase (ACLY), Fatty Acid Synthase (FAS), Fatty Acyl-CoA Elongase 6 (ELOVL6), and Stearoyl-CoA Desaturase-1 (SCD1) in cancer cells. In conclusion, CA mediated reprogramming of glucose processing through TCA cycle via oxidative decarboxylation. The increased oxidative stress, as a result of CA treatment, sensitized cancer cells and, acting on cell biosynthesis and bioenergetics, made HTB-34 cells more susceptible to Met and successfully inhibited neoplastic cells. The combination of Metformin and caffeic acid to suppress cervical carcinoma cells by two independent mechanisms may provide a promising approach to cancer treatment. PMID:28230778

    Purpose: To prove the superiority of concurrent radiochemotherapy (RTCT) over radiotherapy (RT) alone in locally advanced cervical carcinoma. Patients and Methods: In this randomized monocentric phase III study, 566 patients with squamous cell carcinoma of the cervix were included: 284 in arm A (RT) and 282 in arm B (concurrent RTCT with cisplatin 20 mg/m{sup 2} x 5 days). 238 patients (42%) were in stage IIB, 209 (37%) in stage IIIA, and 119 (21%) in stage IIIB. The median follow-up was 62.8 months. RT to the pelvis was delivered to a dose of 46 Gy/23 fractions. A cervical boost was given using the X-ray arch technique or high-dose-rate intracavitary brachytherapy at a dose of 10 Gy. Thereafter, patients were evaluated: those with good response optionally underwent surgery and the others continued RT until 64 Gy/pelvis (with or without CT according to randomization) and 14 Gy/central tumor volume. Results: The 5-year survival rate was statistically significantly superior in the concurrent RTCT group (74%) versus the RT group (64%; p < 0.05). In patients undergoing surgery after RT or RTCT, superior results were obtained, compared to the nonoperated patients: 5-year survival rate 86% versus 53% (p < 0.01). 192 failures were recorded: 109 (38%) after RT alone versus 83 (29%) after concurrent RTCT (p < 0.01). Conclusion: The results of this study prove the obvious superiority of concurrent RTCT with 5-day cisplatin compared to RT alone in patients with locally advanced cervical carcinoma, regarding local control (78% vs. 67%) and 5-year survival rates (74% vs. 64%).

    Objective: To study the characteristics and clinical features of uterine neoplasms developed after radiation ther-apy for cervical carcinoma. Methods: Clinical data of 47 cases of uterine neoplasms occurred following radiation therapy for cervical carcinoma were retrospectively reviewed. Results: The median age at uterine neoplasms diagnosis was 62 years (range: 38-77 years), and the median latency period from initial therapy to development of uterine neoplasms was 14 years (range: 5-35 years). Thirty of 47 cases were endometrial carcinoma, of which 3 were uterine papillary serous carcinoma (UPSC). Seventeen of 47 patients were uterine sarcoma, all of those were carcinosarcoma. The distribution by stage, grade, and histology of 30 cases of endometrial carcinoma was as follows: stage Ib, 1 case; stage Ic, 2 cases; stage Ⅱ, 6; stage Ilia, 4; stage Ⅲb, 2; stage Ⅲc, 11; stage Ⅳ, 4 cases; grade 1, two cases; grade 2, nine; grade 3 (include 3 UPSC patients), seventeen; unknown grade, two; endometried, 27; UPSC, 3 cases; 7 of 30 cases of endometrial carcinoma had recurrences (23.3%), at median time to recurrence was 24 months, and their median survival time was 26 months. The overall 3- and 5-year survival rates were 60% and 38%, respectively. Of the 17 cases of uterine sarcoma, the median survival was 10 months, 6 patients oc-curred recurrence (35.9%), at a median time to recurrence was 9 months, and their median survival was 6 months. The overall 3- and 5-year survival rates were 12% and 0, respectively. Conclusion: The main uterine neoplasms development after radiation therapy for cervical carcinoma is endomethal carcinomas, of which there is a preponderance of high-risk histological subtypes and a poor prognosis. Most of the uterine sarcomas occurred following radiation therapy for cervical carcinoma are carcinosarcomas and the prognosis is very poor.

    Full Text Available My interest for this problem coincided with a patient's request to do something for her. The patient presented a cervical osteoarthritis, with recurrences of cervicalgia, together with inflammatory symptoms: heat, edema, diminished functionality, tissue congestion, pain. After taking anti-inflammatory drugs that were not tolerated by her digestive system, and analgesics that were making her sleepy, the patient gave up her treatment, interrupted her sessions of classical massage, reeducation, physiotherapy, which increased her pain even more, and she got used to the idea that she will always live in pain. A new episode of cervicalgia determined her to ask for help somewhere else. This episode was treated only through lymphatic drainage massage, which really eased her pain, and allowed her to start again the physical therapy, this time with greater ease. Through the absorption and appeal maneuvers, the lymphatic drainage massage allowed the capture of liquids, reestablishing the tissue physiological balance, and contributed to the reconstruction of the damaged tissue, to reducing pain, and to giving back the freedom of movement in the joints, thus allowing a gradual re-adaptation of the cervical spine to movement. In conclusion, the lymphatic drainage massage can be applied as a conservatory, preparatory, and complementary treatment with the therapies that are usually used in the case of cervicalgia.

    Aim:To investigate the apoptosis-inducing effect of oridonin,a diterpenoid isolated from Rabdosia rubescens,in the human cervical carcinoma HeLa cell line.Methods:A morphological analysis,nuclear condensation,and fragmentation of chromatin were monitored using Hoechst 33342 staining. Cell viability was assessed using the 3-(4,5-dimethylthiazol-(2)-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. Cell apoptosis and the apoptosis-related activation in the HeLa cell line were evaluated by flow cytometry and Western blotting. Results:Oridonin suppressed the proliferation of the HeLa cell line in a dose- and time-dependent fashion. Oridonin treatment downregulated the activation of protein kinase B (Akt),the expression of forkhead box class O (FOXO) transcription factor,and glycogen synthase kinase 3 (GSK3). Oridonin also induced the release of cytochrome c accompanied by the activation of caspase-3 and poly-adenosine diphosphate-ribose polymerase cleavage. In addition,Z-D(OMe)-E(OMe)-V-D(OMe)FMK (z-DEVD-fmk),an inhibitor of caspases,prevented caspase-3 activation and abrogated oridonin-induced cell death. Finally,oridonin treatment of the HeLa cell line downregulated the expression of the inhibitor of the apoptosis protein.Conclusion:Our results showed that oridonin-induced apoptosis involved several molecular pathways. Oridonin may suppress constitutively activated targets of phosphatidylinositol 3-kinase (Akt,FOXO,and GSK3) in the HeLa cell line,inhibiting the proliferation and induction of caspase-dependent apoptosis.

    Objective: To investigate 21 HPV genotypes infection in cervical cancer and cervical intraepithelial neoplasia ( CIN) , and the relationship between HPV infections and cervical cancer. Methods:Cases with chronic cervici-tis or abnormal cervical cells detected by liquid-based Thinprep cytology test ( TCT) had 21 HPV genotypes detected and accepted cervical biopsy during colposcopy. HPV infection status in 2 481 cases with cervical carcinoma or cervical intraep-ithelial neoplasia were analyzed. Results: Among 2 481 cases of CIN and cervical carcinoma, HPV-positive patients ac-counted for 85. 0%. There was statistically significant relevance between HPV infection and abnormal cervical histology (P<0. 001, Pearson correlation coefficient=0. 648). HPV16, HPV18 infection were most common in patients with CC and CINⅢ, CINⅡ, followed by HPV58, HPV 33, HPV31, HPV52, HPV45, HPV59, HPV68 subtype infections. In 304 pa-tients who got cervical infection with a subtype of HPV16, HPV18, HPV58, HPV52, HPV33, the incidence of high-grade squamous intraepithelial lesions (HSIL), atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions (LSIL) rose significant (P=0. 002, Pearson correlation coefficient=0. 322). Morover, CC, CIN III and CIN II had a high rate of HSIL, ASCUS. There were significant correlations between abnormal cervical cytology and histological results (P=0. 026, Pearson correla-tion coefficient=0. 172). Conclusion:Infection of high risk HPV types such as HPV16, HPV18, PHV58, HPV33, HPV52, HPV31, HPV45 is the main risk factor of cervical carcinoma ( CC) and precancerous lesion ( CIN) . With high-risk HPV infection, cervical cytologic diagnoses of HSIL, ASCUS and LSIL increase. The correlation between cytological and histological findings for CC and CIN promotes timely detection, prevention, intervention,and effective treatment.%目的::分析宫颈上皮内瘤变( CIN)及宫颈癌( CC

We report here a patient with recurrent esophageal BSC, who was successfully treated by systemic chemotherapy containing 5-fluorouracil (5-FU) and cisplatin (CDDP). A 57-year-old woman was diagnosed as having squamous cell carcinoma of the esophagus upon endoscopic examination. Curative esophagectomy with lymph node dissection was performed under the thoracoscope. The pathological diagnosis of the surgical specimen was BSC.Five months after operation, the patient was diagnosed as having a recurrence of the BSC with metastases to the liver and spleen, and a right paraclavicular lymph node. She was given systemic chemotherapy consisting ofcontinuous infusion of 800 mg/d of 5-FU and 3 h infusion of 20 mg/d of CDDP for 5 consecutive days every 4 wk. The metastatic lesions in the spleen and right paraclavicular lymph node disappeared, and the liver metastasis was apparently reduced in size after 2 courses of chemotherapy. The tumor regression was seen over 6 courses, with progression afterwards.Although subsequent treatment with CPT-11 and CDDP was not effective, docetaxel and vinorelbine temporarily controlled the tumor growth for 2 mo. 5-FU and CDDP combination may be useful for the patients with advanced BSC.

    We report a case of a 45-year-old woman in whom an abnormality was identified by an examination when she was 42 years old. Breast ultrasonography revealed a cyst in the C area of the left breast. Ultrasonography performed 3 years later showed a mass lesion, 1 cm in diameter, in the C area of the left breast. Contrast-enhanced magnetic resonance imaging (MRI) showed a mass shadow. Core needle biopsy was performed, and the pathological diagnosis was mucinous carcinoma. Partial excision of the breast and sentinel lymph node biopsy were performed. The final histopathological diagnosis was mucinous carcinoma( pure type, estrogen receptor[ ER][ +], progesterone receptor[ PgR][ +], human epidermal growth factor receptor-2[ HER2][ 0], Ki67[ 10%], T1N0M0, stage I). One year after the operation, no signs of recurrence or metastasis have been observed. It was difficult to ascertain the presence of a lesion as the patient experienced pregnancy and childbirth during serial observations. An early diagnosis was made by imaging techniques such as consecutive ultrasonography, owing to which we were able to treat the patient early. The findings of this case emphasize the need for serial imaging studies.

    OBJECTIVE:To summarize the progress in study of cervical carcinoma associated stem cells. METHODS:Relative articles between Jan. 2000 to May. 2012 were searched in Medline and CNKI journal with "Uterine cervical carci noma, stem cells and stem cell signaling pathway" as key words,and finally 31 articles were collected. Inclusion criteria:stem cells in normal cervix;cancer stem cells and mesenchymal stem cells isolated from cervical carcinoma;stem cell signa ling pathway associated with treatment resistance to chemotherapy and radiotherapy in cervical carcinoma. RESULTS:The reserved cells isolated from the basal layer in normal cervical tissue showed the capability of cervical stem cells. Cancer stem cells could be separated from cervical cancer cell lines and fresh tissue specimens. These cells showed clear molecular phenotype.such as aldehyde dehydrogenase.some studies suggested that side population cells represented cervical cancer stem cells,which were ABCG2/BCRP1 positive. Enriched as spheroids,cervical cancer stem cells expressed embryonic and adult sternness-related genes (Nanog,Oct-4 and Sox-2) and were capable of generating reproducible tumor phenotypes in nude mice with enhanced tumorigenicity. Mesenchymal stem cells (MSCs) constitute a rare non-hematopoietic population which could be defined according to its ability to self-renew and differentiate into adipose,cartilage,and bone,but contro versy exised regarding their presence and role in solid tumors. MSCs with normal karyotype and multipotential differentia tion were identified and confirmed in cervical cancer tissues. Activation of genes of epithelial-mesenchymal transformation could induce cancer stem cell phenotype. Stem cells signaling pathways contributed to the occurrence,the progression and metastasis,even treatment resistance of cervical cancer, such as the Hedgehog pathway, TGF-β pathway. Modulation or inhibition corresponding pathway might inhibit tumor growth and reduce chemotherapy and

    The analysis of the three-dimensional (3-D) structure of tumoral invasion fronts of carcinoma of the uterine cervix is the prerequisite for understanding their architectural-functional relationship. The variation range of the invasion patterns known so far reaches from a smooth tumor-host boundary surface to more diffusely spreading patterns, which all are supposed to have a different prognostic relevance. As a very decisive limitation of previous studies, all morphological assessments just could be done verbally referring to single histological sections. Therefore, the intention of this paper is to get an objective quantification of tumor invasion based on 3-D reconstructed tumoral tissue data. The image processing chain introduced here is capable to reconstruct selected parts of tumor invasion fronts from histological serial sections of remarkable extent (90-500 slices). While potentially gaining good accuracy and reasonably high resolution, microtome cutting of large serial sections especially may induce severe artifacts like distortions, folds, fissures or gaps. Starting from stacks of digitized transmitted light color images, an overall of three registration steps are the main parts of the presented algorithm. By this, we achieved the most detailed 3-D reconstruction of the invasion of solid tumors so far. Once reconstructed, the invasion front of the segmented tumor is quantified using discrete compactness.

    Porokeratosis is a clonal epidermal disorder of keratinization characterized by annular lesions with an atrophic centre and a hyperkeratotic edge. The cornoid lamella is the histopathological hallmark. Six clinical variants are recognized: porokeratosis of Mibelli; disseminated superficial porokeratosis; disseminated superficial actinic porokeratosis (DSAP); porokeratosis plantaris et palmaris disseminata; punctate porokeratosis and linear porokeratosis. Linear porokeratosis is the type most frequently associated with malignant transformation into squamous cell carcinoma (SCC). It is thought to represent a mosaic form of DSAP and has an incidence of less than 1 in 200 000; treatment options are limited. We describe a patient with systematized linear porokeratosis and multiple SCCs who was successfully treated with bleomycin electrochemotherapy (ECT), a form of intralesional chemotherapy. In view of their large number, the individual SCCs were treated with bleomycin ECT. One year post-treatment the patient remains tumour free. To our knowledge, this is the first case of multiple SCCs treated by ECT in the context of systematized linear porokeratosis. Our case highlights the challenges associated with diagnosing and managing this unusual form of porokeratosis.

    Objective: To study the mechanism, clinical characteristics, therapy regimens, and survival of cervical carcinoma metastases to the brain. Methods: We retrospectively analyzed 11 patients with brain metastases from cervical carcinoma. Results: Two cases were at stage lb, two at IIa, and seven at IIIb, respectively. Histologically, they were squamous cell carcinoma (6 cases), adeno-squamous carcinoma (2 cases), small cell carcinoma (2 cases), or adenocarcinoma (1 cases), poorly differentiated. Eight were accompanied with lung, liver, and bone metastases disease and three had no any other systemic metastases at the time of the brain metastases diagnosis. Two had controlled, and other nine were uncontrolled or progressive primary disease. The median interval from the diagnosis of the primary carcinoma to the detection of brain lesion was 14.6 months. Headache was the most common symptom of brain metastases. Eight of 11 patients developed multiple lesions and other 3 cases had a solitary lesion in brain. The patients were treated by combination of surgery and whole brain radiation therapy (WBRT) (3 cases), stereotactic radiosurgery (SRS) (3 cases), or WBRT (5 cases). The patients had a median survival of 6.6 months. Conclusion: Brain metastases are not always a late complication of cervical carcinoma. The development of the metastases is related to pathological type, poorly differentiation, and advanced stage. Surgery and SRS arc the appropriate therapy regimen for these patients.

    Full Text Available ObjectiveTo investigate the efficacy of short-term nutritional intervention in patients with primary hepatocellular carcinoma treated by transcatheter arterial chemoembolization. MethodsSixty patients with primary hepatocellular carcinoma who were admitted to Beijing Youan Hospital to receive transcatheter arterial chemoembolization from January 2012 to October 2012 were equally and non-randomly divided into two groups: nutrition group and control group. The two groups were all given nutrition guidance after transcatheter arterial chemoembolization. The nutrition group was given 15 g liver essentials twice a day (one in the morning and the other in the evening by oral administration for 4 weeks, while the control group was given routine diet for 4 weeks. Comparison of data between the two groups was made by independent-samples t test. ResultsAfter 4 weeks of continuous treatment, the two groups had significantly increased body weight (P<0.05, arm muscle circumference (P<0.05, and triceps skinfold thickness (P<0.05. The two groups had significantly increased total protein (67±13 g/L vs 72±9 g/L, P=0.04; 66±10 g/L vs 74±8 g/L, P=0.02 after treatment, and there was a significant difference in changes in total protein after treatment between the two groups (P=0.04. The nutrition group had significantly increased albumin (34.7±2.9 g/L vs 39.9±3.5 g/L, P=0.03 and cholinesterase (3342±415 U/L vs 4600±459 U/L, P=0.01 after treatment, and there was a significant difference in changes in albumin (P=0.03 and cholinesterase (P=0.03 after treatment between the two groups. ConclusionFor patients with primary hepatocellular carcinoma treated by transcatheter arterial chemoembolization, oral administration of liver essentials improves their nutritional status and liver function, so as to increase their tolerance to subsequent treatments.

    Full Text Available Background: Rapid industrialization is discharging toxic heavy metals into the environment, disturbing human health in many ways and causing various neurologic, cardiovascular, and dermatologic abnormalities and certain types of cancer. The presence of arsenic in drinking water from different urban and rural areas of the major cities of Pakistan, for example, Lahore, Faisalabad, and Kasur, was found to be beyond the permissible limit of 10 parts per billion set by the World Health Organization. Therefore the present study was initiated to examine the effects of arsenite (As+3 on DNA biosynthesis and cell death. Methods: After performing cytotoxic assays on a human epithelial carcinoma cell line, expression analysis was done by quantitative polymerase chain reaction, western blotting, and flow cytometry. Results: We show that As+3 ions have a dose- and time-dependent cytotoxic effect through the activation of the caspase-dependent apoptotic pathway. In contrast to previous research, the present study was designed to explore the early cytotoxic effects produced in human cells during exposure to heavy dosage of As+3 (7.5 µg/ml. Even treatment for 1 h significantly increased the mRNA levels of p21 and p27 and caspases 3, 7, and 9. It was interesting that there was no change in the expression levels of p53, which plays an important role in G2/M phase cell cycle arrest. Conclusion: Our results indicate that sudden exposure of cells to arsenite (As+3 resulted in cytotoxicity and mitochondrial-mediated apoptosis resulting from up-regulation of caspases.

    The cytotoxic response, cellular uptake, and metabolomic profile of HeLa and HaCaT cell lines treated with cobalt ferrite nanoparticles (CoFe2O4 NPs) were investigated in this study. Cell viability assays showed low cytotoxicity caused by the uptake of the nanoparticles at 2 mg/mL. However, metabolomics revealed that these nanoparticles impacted cell metabolism even when tested at a concentration that presented low cytotoxicity according to the cell viability assay. The two cell lines shared stress-related metabolic changes such as increase in alanine and creatine levels. A reduced level of fumarate was also observed in HeLa cells after treatment with the nanoparticles, and this alteration can inhibit tumorigenesis. Fumarate is considered to be an oncometabolite that can inhibit prolyl hydroxylase, and this inhibition stabilizes HIF1α, one of the master regulators of tumorigenesis that promotes tumor growth and development. In summary, this study showed that nanoparticle-treated HeLa cells demonstrated decreased concentrations of metabolites associated with cell proliferation and tumor growth. The results clearly indicated that treatment with these nanoparticles might cause a perturbation in cellular metabolism.

    Full Text Available INTRODUCTION: Transient hypoxia and subsequent reoxygenation are common phenomena in solid tumors that greatly influence the outcome of radiation therapy. This study was designed to determine how varying cycles of hypoxia/reoxygenation affect the response of cervical carcinoma cells irradiated under oxic and hypoxic conditions and whether this could be modulated by proteasome inhibition. MATERIALS AND METHODS: Plateau-phase SiHa cervical carcinoma cells in culture were exposed to varying numbers of 30-minute cycles of hypoxia/reoxygenation directly before irradiation under oxic or hypoxic conditions. 26S Proteasome activity was blocked by addition of MG-132. Clonogenic survival was measured by a colonyforming assay. RESULTS: Under oxic conditions, repeated cycles of hypoxia/reoxygenation decreased the clonogenic survival of SiHa cells. This effect was even more pronounced after the inhibition of 26S proteasome complex. In contrast, under hypoxic conditions, SiHa cells were radioresistant, as expected, but this was increased by proteasome inhibition. CONCLUSIONS: Proteasome inhibition radiosensitizes oxygenated tumor cells but may also protect tumor cells from ionizing radiation under certain hypoxic conditions.

We investigated whether the α-fetoprotein (AFP response is associated with survival in patients with advanced HCC treated with sorafenib. Methods: We retrospectively reviewed the records of 126 patients with advanced HCC treated with sorafenib between 2007 and 2012. An AFP response was defined as >20% decrease from baseline. At 6–8 weeks after commencing sorafenib, AFP and radiological responses were assessed by modified Response Evaluation Criteria in Solid Tumors. Results: The median overall survival (OS and progression-free survival (PFS were 6.2 and 3.5 months, respectively. Of the study population, a partial response (PR was identified in 5 patients (4.0%, stable disease (SD in 65 patients (51.6%, and progressive disease (PD in 57 patients (44.4%, respectively. AFP non-response was an independent prognostic factor for poor OS (median 10.9 months for AFP response vs 5.2 months for AFP non-response, together with Child-Pugh B, tumor diameter ≥10 cm, and portal vein invasion (all P<0.05, and PFS (median 5.3 months for AFP response vs 2.9 months for AFP non-response, together with tumor diameter ≥10 cm and portal vein invasion (all P<0.05.

    BACKGROUND: Many methods are used to treat liver cancer. Among them, radiofrequency ablation (RFA) is a hot topic because of its advantages. This study was designed to determine the signiifcance of blood alpha-fetoprotein mRNA (AFPmRNA) changes in patients with hepatocellular carcinoma (HCC) treated with RFA. METHODS:The AFPmRNA content in blood samples from HCC patients was determined by reverse transcriptase-polymerase chain reaction (RT-PCR) before RFA and 48 hours, 72 hours, 1 week and 2 weeks later. RESULTS: The blood of 183 patients was negative for AFPmRNA before RFA, but that of 62 of them was positive 72 hours later, then returned to negative after 2 weeks. The blood of 129 patients was positive for AFPmRNA before RFA, but that of 112 of them became negative 2 weeks later;17 patients were still AFPmRNA positive 2 weeks after RFA. CONCLUSIONS: Blood AFPmRNA, which is increased temporarily after RFA, can be used as an objective index for the persistence and recurrence of HCC after RFA.

    Full Text Available Objective: The aim of this study was to investigate the prognostic significance for survival of certain clinical and pathological factors in patients with advanced or metastatic renal cell carcinoma (mRCC treated with chemotherapy. Methods: From 1990 to 2009 sixty seven consecutive patients with mRCC, treated in UMHAT- Dr. G. Stranski, Department of Medical Oncology entered the study. Parameters including some patients characteristics, hematological and pathological parameters, were evaluated for their role as predictors of overall survival. The therapeutic regimens included Interferon- alpha or Medroxyprogesterone acetat. Survival analysis was evaluated by Kaplan- Meier test. The influence of pretreatment characteristics as prognostic factor for survival was analyzed using multivariate stepwise Cox regression analyses. Results: Variables significantly associated with overall survival univariate analysis were performance status >1, thrombocytosis, anemia and number of metastatic sites >1. In multivariate analysis as independent poor prognostic factors were identified poor performance status and multiple sites of metastasis. Conclusion: These results indicated that performance status, presence of elevated platelet counts or anemia as well as well as multiple site of metastasis could be useful prognostic factors in patients with mRCC.

    In SiHa and CaSki cells, E6 and E7-targeting shRNA specifically and effectively knocked down human papillomavirus (HPV) 16 E6 and E7 at the transcriptional level, reduced the E6 and E7 mRNA levels by more than 80% compared with control cells that expressed a scrambled-sequence shRNA. E6 and E7 repression resulted in down-regulation of DNA methyltransferase mRNA and protein expression, decreased DNA methylation and increased mRNA expression levels of tumor suppressor genes, induced a certain apoptosis and inhibited proliferation in E6 and E7 shRNA-infected SiHa and CaSki cells compared with the uninfected cells. Repression of E6 and E7 oncogenes resulted in restoration of DNA methyltransferase suppressor pathways and induced apoptosis in HPV16-positive cervical carcinoma cell lines. Our findings suggest that the potential carcinogenic mechanism of HPV16 through influencing DNA methylation pathway to activate the development of cervical cancer exist, and maybe as a candidate therapeutic strategy for cervical and other HPV-associated cancers.

    To evaluate whether dual-energy computed tomography (DECT)-derived iodine content and iodine overlay could differentiate between normal, inflammatory and metastatic squamous cell carcinoma (SCC) cervical lymph nodes. This study was approved by the institutional review board. Sixteen patients with normal lymph nodes, 20 patients with enlarged nodes draining deep cervical inflammations and 23 patients with pathologically proved metastatic SCC nodes who underwent contrast enhanced DECT were retrospectively identified. Iodine content and overlay of 36 normal, 43 inflammatory and 52 metastatic lymph nodes were calculated using circular regions of interest and compared among the three groups. A receiver operating characteristic (ROC) curve was used to determine the sensitivity and specificity of iodine content and overlay for diagnosis of metastatic nodes. Iodine content (mg/ml) was significantly lower for metastatic lymph nodes (2.34 ± 0.45) than for normal (2.86 ± 0.37) and inflammatory (3.53 ± 0.56) lymph nodes, P < 0.0001. Iodine overlay (HU) was also significantly lower for metastatic lymph nodes (47 ± 11.6) than normal (57.4 ± 8.2) and inflammatory nodes (69.3 ± 11.5), P < 0.0001. The areas under the ROC curve for iodine content and iodine overlay were 0.923 and 0.896. DECT-derived iodine content and overlay differ significantly among normal, inflammatory and metastatic SCC cervical lymph nodes. (orig.)

    The aim of our study was to investigate the effect of Patrinia scabra Bunge polysaccharide (PSB-P2) on cervical cancer cell (U14)-bearing mice. The tumor weight of mice treated with PSB-P2 (40, 80 mg/kg b.w.) was significantly lower than that of the control group and serum lactate dehydrogenase (LDH) activity was decreased, while serum alkaline phosphatase (AKP) level was only changed slightly. Meanwhile, the number of apoptotic tumor cells was significantly increased in the mice by the treatment of PSB-P2 (40, 80 mg/kg b.w.). At the same time, cell cycle analysis showed the accumulation of tumor cells in the G0/G1 phase and a relative decrease in the S phase. On the other hand, using the reverse transcription-polymerase chain reaction (RT-PCR) assay, PSB-P2 (40, 80 mg/kg b.w.) showed the up-regulation of p53 and Bax, and significant inhibition of Bcl-2 in tumor tissues. It suggests a possible mechanism of the inhibitory effect of PSB-P2 on tumor growth.

    Purpose: Cervical cancer treatment is associated with a risk of urinary adverse events (UAEs) such as ureteral stricture and vesicovaginal fistula. We sought to measure the long-term UAE risk after surgery and radiation therapy (RT), with confounding controlled through propensity-weighted models. Methods and Materials: From the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, we identified women ≥66 years old with nonmetastatic cervical cancer treated with simple surgery (SS), radical hysterectomy (RH), external beam RT plus brachytherapy (EBRT+BT), or RT+surgery. We matched them to noncancer controls 1:3. Differences in demographic and cancer characteristics were balanced by propensity weighting. Grade 3 to 4 UAEs were identified by diagnosis codes plus treatment codes. Cumulative incidence was measured using Kaplan-Meier methods. The hazard associated with different cancer treatments was compared using Cox models. Results: UAEs occurred in 272 of 1808 cases (17%) and 222 of 5424 (4%) controls; most (62%) were ureteral strictures. The raw cumulative incidence of UAEs was highest in advanced cancers. UAEs occurred in 31% of patients after EBRT+BT, 25% of patients after RT+surgery, and 15% of patients after RH; however, after propensity weighting, the incidence was similar. In adjusted Cox models (reference = controls), the UAE risk was highest after RT+surgery (hazard ratio [HR], 5.07; 95% confidence interval [CI], 2.32-11.07), followed by EBRT+BT (HR, 3.33; 95% CI, 1.45-7.65), RH (HR, 3.65; 95% CI, 1.41-9.46) and SS (HR, 0.99; 95% CI, 0.32-3.01). The higher risk after RT+surgery versus EBRT+BT was statistically significant, whereas, EBRT+BT and RH were not significantly different from each other. Conclusions: UAEs are common after cervical cancer treatment, particularly in patients with advanced cancers. UAEs are more common after RT, but these women tend to have the advanced cancers. After propensity weighting, the risk after RT was similar

    Full Text Available The objective of the study was to determine the dynamics of precancerous lesions in women of a cohort treated for cervical intraepithelial neoplasia (CIN and followed up over the next two years. The conditional probability of failure was calculated using the Kaplan-Meier method, and the raw and adjusted hazard ratios (HR were determined using Cox regression with a p-value entry of < 0.05. Of the 237 women who were treated, 51.5% were accompanied over 24 months, and treatment failed for 21.9% of those accompanied. Women who had five or more pregnancies (adjusted HR = 3.10, 95%CI: 1.28-7.51 or an initial histological diagnosis of CIN II/III demonstrated an independent risk of treatment failure (adjusted HR = 3.14, 95%CI: 1.20-8.19. Being in a stable relationship was a protective factor against treatment failure (adjusted HR = 0.47, 95%CI: 0.24-0.89. A history of more frequent pregnancies and a histological diagnosis of CIN II/III are directly correlated with risk of CIN treatment failure, whereas being in a stable relationship is inversely correlated with this risk.

    Cadmium (Cd) is a toxic and carcinogenic metal naturally occurring in the earth’s crust. A common route of human exposure is via diet and cadmium accumulates in the liver. The effects of Cd exposure on gene expression in human hepatocellular carcinoma (HepG2) cells were examined in this study. HepG2 cells were acutely-treated with 0.1, 0.5, or 1.0 μM Cd for 24 hours; or chronically-treated with 0.01, 0.05, or 0.1 μM Cd for three weeks and gene expression analysis was performed using Affymetrix GeneChip® Human Gene 1.0 ST Arrays. Acute and chronic exposures significantly altered the expression of 333 and 181 genes, respectively. The genes most upregulated by acute exposure included several metallothioneins. Downregulated genes included the monooxygenase CYP3A7, involved in drug and lipid metabolism. In contrast, CYP3A7 was upregulated by chronic Cd exposure, as was DNAJB9, an anti-apoptotic J protein. Genes downregulated following chronic exposure included the transcriptional regulator early growth response protein 1. Ingenuity Pathway Analysis revealed that the top networks altered by acute exposure were lipid metabolism, small molecule biosynthesis, and cell morphology, organization, and development; while top networks altered by chronic exposure were organ morphology, cell cycle, cell signaling, and renal and urological diseases/cancer. Many of the dysregulated genes play important roles in cellular growth, proliferation, and apoptosis, and may be involved in carcinogenesis. In addition to gene expression changes, HepG2 cells treated with cadmium for 24 hours indicated a reduction in global levels of histone methylation and acetylation that persisted 72 hours post-treatment.

    AIM: The aim of the study was to evaluate the predictive factors of survival in patients with locally advanced squamous cell esophageal carcinoma (LASCOC) treated with definitive chemoradiotherapy (CRT)regimen based on the 5FU/CDDP combination.METHODS: All patients with LASCOC treated with a definitive CRT using the 5FU/CDDP combination between 1994 and 2000 were retrospectively included.Clinical complete response (CCR) to CRT was assessed by esophageal endoscopy and CT-scan 2 mo after CRT completion. Prognostic factors of survival were assessed using univariate and multivariate analysis by the Cox regression model.RESULTS: A total of 116 patients were included in the study. A CCR to CRT was observed in 86/116 (74.1%).The median survival was 20 mo (range 2-114) and the 5-year survival was 9.4%. Median survival of responder patients to CRT was 25 mo (range 3-114) as compared to 9 mo (range 2-81) in non-responder patients (P <0.001). In univariate analysis, survival was associated with CCR (P < 0.001), WHO performance status < 2 (P= 0.01), tumour length < 6 cm (P = 0.045) and weight loss < 10% was in limit of significance (P = 0.053). In multivariate analysis, survival was dependant to CCR (P< 0.0001), weight loss < 10% (P = 0.034) and WHO performance < 2 (P = 0.046).CONCLUSION: Our results suggest that survival in patients with LASCOC treated with definitive CRT was correlated to CCR, weight loss and WHO performance status.

    A retrospective study. To report the incremental hospital resources consumed with treating adverse events experienced by Medicare beneficiaries undergoing a two or three vertebrae level cervical spinal fusion. Hospitals are increasingly at financial risk for patients experiencing adverse events due "pay for performance". Little is known about incremental resources consumed when treating patients who experienced an adverse event following cervical spinal fusions. Fiscal years 2013 and 2014 Medicare Provider Analysis and Review file was used to identify 86,265 beneficiaries who underwent 2 or 3 vertebrae level cervical spinal fusion. International Classification of Diseases-9-Clinical Modification diagnostic and procedure codes were used to identify ten adverse events. This study estimated both the observed and risk-adjusted incremental hospital resources consumed (cost (2014 US $) and length-of-stay [LOS]) in treating beneficiaries experiencing each adverse event. Overall, 6.2% of beneficiaries undergoing cervical spinal fusion experienced at least one of the study's adverse events. Beneficiaries experiencing any complication consumed significantly more hospital resources (incremental cost of $28,638) and had longer LOS (incremental stays of 9.1 days). After adjusting for patient demographics and comorbid conditions, incremental cost of treating adverse events ranged from a high of $42,358 (infection) to a low of $10,100 (dural tear). Adverse events frequently occur and add substantially to the hospital costs of patients undergoing cervical spinal fusion. Shared decision-making instruments should clearly provide these risk estimates to the patient prior to surgical consideration. Investment in activities that have been shown to reduce specific adverse events is warranted, and this study may allow health systems to prioritize performance improvement areas. 3.

    To evaluate whether dual-energy computed tomography (DECT)-derived iodine content and iodine overlay could differentiate between normal, inflammatory and metastatic squamous cell carcinoma (SCC) cervical lymph nodes. This study was approved by the institutional review board. Sixteen patients with normal lymph nodes, 20 patients with enlarged nodes draining deep cervical inflammations and 23 patients with pathologically proved metastatic SCC nodes who underwent contrast enhanced DECT were retrospectively identified. Iodine content and overlay of 36 normal, 43 inflammatory and 52 metastatic lymph nodes were calculated using circular regions of interest and compared among the three groups. A receiver operating characteristic (ROC) curve was used to determine the sensitivity and specificity of iodine content and overlay for diagnosis of metastatic nodes. Iodine content (mg/ml) was significantly lower for metastatic lymph nodes (2.34 ± 0.45) than for normal (2.86 ± 0.37) and inflammatory (3.53 ± 0.56) lymph nodes, P overlay (HU) was also significantly lower for metastatic lymph nodes (47 ± 11.6) than normal (57.4 ± 8.2) and inflammatory nodes (69.3 ± 11.5), P overlay were 0.923 and 0.896. DECT-derived iodine content and overlay differ significantly among normal, inflammatory and metastatic SCC cervical lymph nodes. • Derived iodine content can be calculated from contrast-enhanced dual-energy CT. • Derived iodine content and iodine overlay could help characterise cervical lymph nodes. • Iodine parameters were significantly lower in metastatic lymph nodes than normal/inflammatory lymph nodes. • Iodine content appears more sensitive than iodine overlay for lymph node characterisation.

    Objective To study the expression of AQPs in normal cervical tissue, cervical intraepithelial neoplasia and squamuus cervical carcinoma, and analyze the correlations of AQPs with clinicopathological parameters of squamous cervical carcinoma and explore their possible role during progression to squamous cervical carcinoma. Methods Immunohistochemical staining technology was applied to detect the expression and position of AQPs in 16 cases of normal cervical tissues, 37 cases of cervical intraepithelial neoplasia tissues and 47 cases of squamous cervical carcinoma specimens. Double immunohistochemistry was used to delect the co - expression of VECF and AQP1, AQP3, AQP8 in squamous cervical carcinoma. Results The expression of AQP1 was demonstrated in microvascular endothelial cells of the three groups of cervical tissue. The expression of AQP3, AQP4, AQP5 and AQP8 were detected in cytoplasm and (or) membrane of squamous cells in cervical normal tissue, atypia cells in cervical intraepithelial neoplasia and carcinoma cells in squamous cervical carcinoma. AQP1 was highly expressed in the CIN when compared with normal cervical tissue and squamous cervical carcinoma (P < 0. 05 ) . In the cases of squamous cervical carcinoma, AQP1 expressed in FIGO stage I was higher than thai in stage II (P < 0,05 ). The expression of AQP3, AQP4, AQP5 and AQP8 was gradually increasing as the tumor progresses. AQP3 was highly expressed in the poorly - differentiated group as compared with moderately - and well - differentiated group ( P < 0. 05 ). Co - expression of the VEGF and AQPs (including AQP1, AQP3 and AQP8) were detected in squamous cervical carcinoma. Conclusion AQP1, AQP3, AQP4, AQP5 and AQP8 may play certain roles during the progression of squamous cervical carcinoma, while AQP1, AQP3 and AQP8 may play a role in the angiogenesis of squamous cervical carcinoma.%目的 研究水通道蛋白(aquaporins,AQPs)在正常宫颈组织、宫颈上皮内瘤样变(CIN)和宫颈鳞癌中

    Background: Ultrasonography has been proposed to enhance preoperative assessment of cervical lymph node status in patients with papillary thyroid carcinoma (PTC). Management is most controversial for patients with a clinically negative (cN0) neck. We aimed to evaluate the diagnostic properties of ultrasonography in the detection of cervical lymph node metastasis in patients with PTC. Materials and methods: Studies evaluating the diagnostic accuracy of Ultrasonography in the diagnosis of cervical lymph node metastasis in patients with PTC were systematically searched for in the MEDLINE, EMBASE, Cancerlit and Cochrane Library and other database from January 1995 to November 2010. Two reviewers independently abstracted data including research design, sample size, imaging technique and technical characteristics, method of image interpretation. By patient-based and region- or node-based data analyses, we determined pooled sensitivities and specificities across studies, and constructed summary receiver operating characteristic curves, and area under summary receiver operating characteristic curves were calculated. Results: The pooled patient-based sensitivity for ultrasonography was 0.72 (95% CI, 0.46-0.88), specificity was 0.98 (95% CI, 0.84-1.00), and the area under the curve (AUC) was 0.94 (95% CI, 0.92-0.0.96). The pooled region- or node-based sensitivity for ultrasonography was 0.63 (95% CI, 0.47-0.76), specificity was 0.93 (95% CI, 0.73-0.99), and the AUC was 0.81 (95% CI, 0.77-0.84). For lesion-based analysis, the subgroup of lateral compartment lymph node involvement was found to have the highest sensitivity (0.72, 95% CI 0.68-0.75) and specificity (0.97, 95% CI 0.93-0.99) among the studies (p < 0.05). Study sensitivity was not correlated with the prevalence of cervical lymph node metastasis (patient-based: R{sup 2} = 0.0196, p = 0.7915; region- or node-based: R{sup 2} = 0.3835, p = 0.1381). Conclusions: We conclude that preoperative ultrasonography is a good

    Purpose: To assess, in a retrospective cohort study, rates and predictors of first and recurrent stroke in patients treated with cranial irradiation (CRT) and/or cervical irradiation at ≤18 years of age. Methods and Materials: We performed chart abstraction (n=383) and phone interviews (n=104) to measure first and recurrent stroke in 383 patients who received CRT and/or cervical radiation at a single institution between 1980 and 2009. Stroke was defined as a physician diagnosis and symptoms consistent with stroke. Incidence of first stroke was number of first strokes per person-years of observation after radiation. We used survival analysis techniques to determine cumulative incidence of first and recurrent stroke. Results: Among 325 subjects with sufficient follow-up data, we identified 19 first strokes (13 ischemic, 4 hemorrhagic, 2 unknown subtype) occurring at a median age of 24 years (interquartile range 17-33 years) in patients treated with CRT. Imaging was reviewed when available (n=13), and the stroke was confirmed in 12. Overall rate of first stroke was 625 (95% confidence interval [CI] 378-977) per 100,000 person-years. The cumulative incidence of first stroke was 2% (95% CI 0.01%-5.3%) at 5 years and 4% (95% CI 2.0%-8.4%) at 10 years after irradiation. With each 100-cGy increase in the radiation dose, the stroke hazard increased by 5% (hazard ratio 1.05; 95% CI 1.01-1.09; P=.02). We identified 6 recurrent strokes; 5 had available imaging that confirmed the stroke. Median time to recurrence was 15 months (interquartile range 6 months-3.2 years) after first stroke. The cumulative incidence of recurrent stroke was 38% (95% CI 17%-69%) at 5 years and 59% (95% CI 27%-92%) at 10 years after first stroke. Conclusion: Cranial irradiation puts childhood cancer survivors at high risk of both first and recurrent stroke. Stroke prevention strategies for these survivors are needed.

    To compare three-dimensional (3D) T2-weighted turbo spin-echo (TSE) with multiplanar two-dimensional (2D) T2-weighted TSE for the evaluation of invasive cervical carcinoma. Seventy-five patients with cervical carcinoma underwent MRI of the pelvis at 3.0 T, using both 5-mm-thick multiplanar 2D (total acquisition time = 12 min 25 s) and 1-mm-thick coronal 3D T2-weighted TSE sequences (7 min 20 s). Quantitative analysis of signal-to-noise ratio (SNR) and qualitative analysis of image quality were performed. Local-regional staging was performed in 45 patients who underwent radical hysterectomy. The estimated SNR of cervical carcinoma and the relative tumour contrast were significantly higher on 3D imaging (P < 0.0001). Tumour conspicuity was better with the 3D sequence, but the sharpness of tumour margin was better with the 2D sequence. No significant difference in overall image quality was noted between the two sequences (P = 0.38). There were no significant differences in terms of the diagnostic accuracy, sensitivity, and specificity of parametrial invasion, vaginal invasion, and lymph node metastases. Multiplanar reconstruction 3D T2-weighted imaging is largely equivalent to 2D T2-weighted imaging for overall image quality and staging accuracy of cervical carcinoma with a shorter MR data acquisition, but has limitations with regard to the sharpness of the tumour margin. circle 3D T2-weighted MR sequence is equivalent to 2D for cervical carcinoma staging.

    To compare the efficacy among acupuncture based on "jin" theory, regular acupuncture and western medication. A total of 95 cases, by using incomplete randomization method, were divided into a "jin" theory acupuncture group (32 cases), a regular acupuncture group (31 cases) and a medication group (32 cases). Patients in the "jin" theory acupuncture group were treated with acupuncture based on "jin" theory which included the "gather" and "knot" points on the affected side: positive reacted points, Fengchi (GB 20), Tianrong (SI 17), Tianyou (TE16) and Yiming (EX-HN14) as the main acupoints, while the Ermen (TE 21), Tinggong (SI 19) and Tinghui (GB 2) and zhigou (TE 6) as the auxiliary acpoints; the treatment was given once a day. Patients in the regular acupuncture group were treated with regular acupuncture at Tinggong (SI 19), Tin- ghui (GB 2) and Ermen (TE 21) and other matched acupoints based on syndrome differentiation, once a day. Pa- tients in the medication group were treated with oral administration of betahistine mesylate, three times a day. Ten days of treatment were taken as one session in three groups, and totally 2 sessions were given. Visual analogue scale (VAS), tinnitus handicap inventory (THD), and tinnitus severity assessment scale (TSIS) were evaluated before and after treatment; also the clinical efficacy was compared among three groups. There are 5 drop-out cases du- ring the study. After the treatment, the VAS, THI and TSIS were improved in three groups (all P tinnitus.

    Full Text Available O planejamento terapêutico dos tumores da laringe inclui a possibilidade de esvaziamento cervical uni ou bilateral. OBJETIVO: Avaliar a prevalência e localização de metástases linfonodais bilaterais ou contralaterais nos tumores de laringe. CASUÍSTICA E MÉTODO: Estudo longitudinal retrospectivo de 272 prontuários de pacientes com carcinoma epidermoide de laringe tratados entre 1996 e 2004, selecionados 104 submetidos à cirurgia com esvaziamento cervical. Avaliada a incidência de metástases bilaterais ou contralaterais, de acordo com a localização e extensão do tumor primário, considerando os subsítios anatômicos e a linha mediana. RESULTADOS: A prevalência de metástases contralaterais nos tumores lateralizados foi de 3,5% nas lesões glóticas e 26% nas lesões supraglóticas. As metástases contralaterais foram infrequentes nos casos N0. Tanto no esvaziamento eletivo como no terapêutico, os níveis linfonodais IIa e III foram os mais acometidos. CONCLUSÃO: Nas lesões glóticas lateralizadas, mesmo nos tumores transglóticos, não há necessidade de esvaziamento contralateral eletivo. Nas lesões da supraglote sem metástases ipsilaterais, a incidência de metástases ocultas não justifica o esvaziamento eletivo contralateral. A linha mediana não é um indicador fidedigno do risco de metástases contralaterais nos tumores da laringe.Unilateral or bilateral neck dissection must be considered in the treatment of laryngeal cancer AIM: To evaluate the prevalence of contralateral metastases in larynx cancer and distribution of these metastases according to lymph node levels in the neck. METHOD: Retrospective longitudinal study of 272 charts from patients with squamous cell cancer of the larynx treated between 1996 and 2004; and we selected 104 surgical cases submitted to neck dissection. We evaluated the incidence of bilateral or contralateral metastases, according to the location and extension of the primary tumor

    Mimusops elengi (M. elengi) Linn. (Sapotaceae) has been used as a folk medicine in wound healing, and the treatment of pain, and inflammation in many parts of India. The purpose of this investigation was to explore the antitumor activity of methanol extract of M. elengi (MEME) in Swiss albino mice against Ehrlich ascites carcinoma (EAC) cell line. Twenty-four hours after intraperitoneal (i.p.) inoculation of tumor (EAC) cells in mice (n = 12), MEME was administered at 200 and 300 mg/kg body weight daily for 9 consecutive days. On day 10, half of the mice were dissected and the rest were kept alive for assessment of increase in life span. The antitumor effect of MEME was assessed by evaluating tumor volume, viable and nonviable tumor cell count, tumor weight, hematological parameter, and biochemical estimations. In vivo antioxidant parameters were assayed by estimating liver tissue enzyme. In vitro cytotoxicity assay of MEME was measured by using trypan blue exclusion method. MEME showed significant (p MEME-treated mice as compared to EAC control. MEME also showed direct cytotoxicity on EAC cell line in a dose-dependent manner. The present study demonstrates that M. elengi leaves exhibited antitumor activity in Swiss mice, which may be due to its cytotoxic effect and antioxidant properties.

    The purpose of this prospective study was to determine the incidence of thyroid dysfunction in cancer patients receiving immunotherapy with interleukin-2 (IL-2) alone, and to assess the relationship of hypothyroidism to clinical response. A cohort of 281 consecutive patients with metastatic melanoma or renal carcinoma were treated with IL-2 alone from July 1, 1989 until June 30, 1993. The majority (n = 216) received high-dose IL-2 and the remainder (n = 65) received low-dose therapy. Thyroid function was measured before, during, and after immunotherapy. Forty-one percent of initially euthyroid patients developed thyroid dysfunction after starting high-dose IL-2-alone therapy. The most common abnormality was hypothyroidism, occurring in 35% of patients, although moderate or severe hypothyroidism requiring thyroid hormone replacement occurred in 9% of patients. Hypothyroidism was related to duration of IL-2 therapy and was not associated with clinical response. Hyperthyroidism developed in 7% of previously euthyroid patients receiving high-dose IL-2. Overall, the incidence of thyroid dysfunction was similar in the high- and low-dose IL-2 regimens. In conclusion, thyroid dysfunction is a common sequela of IL-2 therapy. Thyroid function should be measured routinely in cancer patients receiving IL-2-based treatment. It is recommended that thyroid hormone replacement be given to patients with moderate or severe hypothyroidism.

    Hepatocellular carcinoma (HCC) with gastric metastasis is extremely rare. There have been few reports on curative surgical resection for gastric metastasis of HCC. We herein report such a case successfully treated by simultaneous surgical resection. A 73-year-old male was admitted for evaluation and treatment of a liver tumor. Computed tomography showed an exophytic tumor of 170 mm in diameter located in the left lobe of the liver with poor delineation to the gastric wall. Upper gastrointestinal endoscopy revealed a submucosal tumor with ulceration in the antrum of the stomach. With a diagnosis of HCC with invasion to the gastric wall, an en bloc resection was planned, and the patient underwent laparotomy. The patients underwent left hemihepatectomy with partial resection of the stomach for adhesion and distal gastrectomy for the tumor. Pathological examination of the liver tumor revealed poorly differentiated HCC, and pathological diagnosis of the tumor in the submucosal and muscular layer of the stomach was compatible with metastasis from HCC, which was separate from the liver tumor. Therefore, we diagnosed the tumor as HCC with hematogenous gastric metastasis. The patient remains well with no evidence of tumor recurrence as of 13 months after resection.

    This study aimed to investigate the occurrences of post-irradiation chronic suppurative otitis media (CSOM), otitis media with effusion (OME), chronic rhinosinusitis (CRS), and their interrelationship in nasopharyngeal carcinoma (NPC) patients treated by intensity-modulated radiotherapy (IMRT). A retrospective review of medical records and magnetic resonance imaging for NPC patients across a 5-year follow-up was conducted. Rhinosinusitis was diagnosed and staged by Lund-Mackay system. A total of 102 patients were enrolled in the study. On the 5th year following IMRT, 8 patients (7.8 %), 30 patients (29.4 %), and 17 patients (16.7 %) suffered from IMRT-induced CSOM, post-irradiation OME, and CRS, respectively. Analysis by logistic regression showed a lack of association between the occurrence of post-irradiation OME and CRS (P = 0.06). These observations indicated that the modern radiotherapy technique exhibits capability in decreasing the incidences of CSOM and CRS comparing to the data of traditional radiotherapy. But post-irradiation OME was still encountered in more than one-quarter of long-term survivors of NPC. Of note, rhinosinusitis in NPC survivors does not predispose to the development of post-irradiation OME, suggesting nasal irrigation might be unnecessary for the management of OME following radiotherapy.

    In the past decade, a variety of interventional procedures have been employed for local control of hepatocellular carcinoma (HCC). These include transcather arterial chemoembolization (TACE) and several tumour ablation techniques, such as percutaneous ethanol injection (PEI),radio-frequency ablation (RFA), or percutaneous microwave coagulation therapy (PMC), laser-induced interstitial thermotherapy (LITT), etc. For a definite assessment of the therapeutic efficacy of interventional procedures,histological examination using percutaneous needle biopsy may be the most definite assessment of the therapeutic efficacy of interventional therapy, however, it is invasive and the specimen retrieved does not always represent the entire lesion owing to sampling errors. Therefore, computed tomography (CT) and magnetic resonance imaging (MRI) play a crucial role in follow-up of HCC treated by interventional procedures, by which the local treatment efficacy, recurrent disease and some of therapy-induced complications are evaluated. Contrast enhanced axial imaging (CT or MR imaging) may be the most sensitive test for assessing the therapeutic efficacy. The goal of the review was to describe the value of CT and MRI in the evaluation of interventional treatments.

    The value of blood tests as prognostic factors in patients with recurrent rectal carcinomas treated with radiotherapy was studied in one retrospective (n=114, 1976-1984) and one prospective (n=100, 1985-1989) group of patients. The retrospective group was used for validation of the results from the prospective group. In univariate survival analyses, 19 of totally 38 variables significantly correlated to the survival. Of 13 significant blood parameters, lactate dehydrogenase (LD), erythrocyte sedimentation rate (ESR), alpha[sub 1]-, alpha[sub 2]-globulin, fibrinogen, carcinoembryonic antigen (CEA), C-reactive protein (CRP), haptoglobin, granulocytosis and thrombocytosis were the most important ones (p[<=]0.01). In the multivariate analyses (Cox regression) of the prospective group, LD, alpha[sub 1]-globulin, diagnosed liver metastases and CEA were found to be significant predictors of survival. A prognostic index was derived from the prospective group including ESR, LD and relapse-free interval. This clearly separated the patients in the retrospective group into one low-and one high-risk group. (orig.).

    To evaluate the outcome of ductal carcinoma in situ (DCIS) patients who underwent surgery followed by radiation therapy (RT). We retrospectively reviewed 106 DCIS patients who underwent surgery followed by postoperative RT between 1994 and 2006. Ninety-four patients underwent breast-conserving surgery, and mastectomy was performed in 12 patients due to extensive DCIS. Postoperative RT was delivered to whole breast with 50.4 Gy/28 fx. Tumor bed boost was offered to 7 patients (6.6%). Patients with hormonal receptor-positive tumors were treated with hormonal therapy. The median follow-up duration was 83.4 months (range, 33.4 to 191.5 months) and the median age was 47.8 years. Ten patients (9.4%) had resection margin <1 mm and high-grade and estrogen receptor-negative tumors were observed in 39 (36.8%) and 20 (18.9%) patients, respectively. The 7-year ipsilateral breast tumor recurrence (IBTR)-free survival rate was 95.3%. Resection margin (<1 or ≥1 mm) was the significant prognostic factor for IBTR in univariate and multivariate analyses (p < 0.001 and p = 0.016, respectively). Postoperative RT for DCIS can achieve favorable treatment outcome. Resection margin was the important prognostic factor for IBTR in the DCIS patients who underwent postoperative RT.

    Purpose: This study was designed to determine the technical feasibility, safety, efficacy, and potential to downstage patients to within transplantation criteria when treating patients with hepatocellular carcinoma (HCC) of the caudate lobe using Y90 radioembolization. Methods: During a 4-year period, 8 of 291 patients treated with radioembolization for unresectable HCC had disease involving the caudate lobe. All patients were followed for treatment-related clinical/biochemical toxicities, serum tumor marker response, and treatment response. Imaging response was assessed with the World Health Organization (WHO) and European Association for the Study of the Liver (EASL) classification schemes. Pathologic response was reported as percent necrosis at explantation. Results: Caudate lobe radioembolization was successfully performed in all eight patients. All patients presented with both cirrhosis and portal hypertension. Half were United Network for Organ Sharing (UNOS) stage T3 (n = 4, 50%). Fatigue was reported in half of the patients (n = 4, 50%). One (13%) grade 3/4 bilirubin toxicity was reported. One patient (13%) showed complete tumor response by WHO criteria, and three patients (38%) showed complete response using EASL guidelines. Serum AFP decreased by more than 50% in most patients (n = 6, 75%). Four patients (50%) were UNOS downstaged from T3 to T2, three of who underwent transplantation. One specimen showed histopathologic evidence of 100% complete necrosis, and two specimens demonstrated greater than 50% necrosis. Conclusions: Radioembolization with yttrium-90 appears to be a feasible, safe, and effective treatment option for patients with unresectable caudate lobe HCC. It has the potential to downstage patients to transplantation.

    Endometrial carcinoma is one of the most common malignancies in the female genital tract, usually treated by surgery and radiotherapy. Chemotherapy is used when endometrial carcinoma is associated with widespread metastasis or when the tumor recurs after radiation therapy. In the present study, we demonstrate that the tyrosine kinase receptor inhibitor Sunitinib reduces cell viability, proliferation, clonogenicity and induces apoptotic cell death in endometrial carcinoma cell lines, which is not due to its action through the most known targets like VEGFR, nor through EGFR as demonstrated in this work. Interestingly, Sunitinib reduces NFκB transcriptional activity either at basal level or activation by EGF or TNF-α. We observed that Sunitinib was able to inhibit the Bortezomib-induced NFκB transcriptional activity which correlates with a decrease of the phosphorylated levels of IKKα and β, p65 and IκBα. We evaluated the nature of the interaction between Sunitinib and Bortezomib by the dose effect method and identified a synergistic effect (combination index < 1). Analogously, silencing of p65 expression by lentiviral-mediated short-hairpin RNA delivery in Bortezomib treated cells leads to a strongly increased sensitivity to Bortezomib apoptotic cell death. Altogether our results suggest that the combination of Sunitinib and Bortezomib could be considered a promising treatment for endometrial carcinoma after failure of surgery and radiation.

    Background and purpose It is known that fluorine-18 fluorodeoxyglucose PET/computed tomography (CT) segmentation algorithms have an impact on the metabolic tumor volume (MTV). This leads to some uncertainties in PET/CT guidance of tumor radiotherapy. The aim of this study was to investigate the effect of segmentation algorithms on the PET/CT-based MTV and their correlations with the gross tumor volumes (GTVs) of cervical primary squamous cell carcinoma. Materials and methods Fifty-five patients with International Federation of Gynecology and Obstetrics stage Ia∼IIb and histologically proven cervical squamous cell carcinoma were enrolled. A fluorine-18 fluorodeoxyglucose PET/CT scan was performed before definitive surgery. GTV was measured on surgical specimens. MTVs were estimated on PET/CT scans using different segmentation algorithms, including a fixed percentage of the maximum standardized uptake value (20∼60% SUVmax) threshold and iterative adaptive algorithm. We divided all patients into four different groups according to the SUVmax within target volume. The comparisons of absolute values and percentage differences between MTVs by segmentation and GTV were performed in different SUVmax subgroups. The optimal threshold percentage was determined from MTV20%∼MTV60%, and was correlated with SUVmax. The correlation of MTViterative adaptive with GTV was also investigated. Results MTV50% and MTV60% were similar to GTV in the SUVmax up to 5 (P>0.05). MTV30%∼MTV60% were similar to GTV (P>0.05) in the 50.05) in the 100.05) in the SUVmax of at least 15 group. MTViterative adaptive was similar to GTV in both total and different SUVmax groups (P>0.05). Significant differences were observed among the fixed percentage method and the optimal threshold percentage was inversely correlated with SUVmax. The iterative adaptive segmentation algorithm led to the highest accuracy (6.66±50.83%). A significantly positive correlation was also observed between MTViterative

    Purpose: The purpose of this study is to assess the dosimetric parameters of cervical carcinoma treatment using 3 different radiation therapy delivery Methods: volumetric-modulated arc therapy (VMAT), the static-field dynamic multileaf collimator intensity-modulated radiation therapy (dIMRT) and the static-field step-and-shoot intensity-modulated radiotherapy (ssIMRT). Methods: Twenty patients with cervical carcinoma were selected to be planned with dual arc VMAT, dIMRT and ssIMRT using Monaco 3.3 TPS on the Axesse™ linear accelerator in this investigation. The total dose of the planning target volume (PTV) is 60Gy. The homogeneity index (HI), conformity index (CI), dose volume histograms (DVHs), delivery efficiency, dose of organs at risks (bladder, rectum, and femoral heads), were all measured. Results: Dose distribution in 3 different radiation therapy delivery methods satisfied clinical requirements. Mean HI of PTV with VMAT, dIMRT and ssIMRT is 1.08, 1.10, and 1.09 (p>0.05). Mean CI of PTV with VMAT, dIMRT and ssIMRT is 0.82, 0.8 and 0.8 (p>0.05). For the DVH of V10, V20 and V30 in bladder, there was a significant difference: VMAT>dIMRT=ssIMRT (p <0.05). For the DVH of V40 and V50, there was a significant difference: VMAT dIMRT >ssIMRT (p <0.05). Conclusion: The results show that VMAT has a great advantage in delivery efficiency than dIMRT and ssIMRT, without compromise to the PTV coverage, HI and CI. The delivery methods should be considered under the actual cervical carcinoma radiotherapy situation.
