Purpose : To evaluate the treatment results and prognostic factors after radiotherapy in stage IIB uterine cervix cancer. Materials and methods : We retrospectively analyzed the records of 90 patients with stage IIB uterine cervix cancer who received radiotherapy between 9/94 and 12/99. Age was ranged from 28 to 79 years (median 57). Tumor size was $\geq4\;cm$ in 64 patients. Preteatment SCC level was measured in 75 patients. Twenty nine patients received conventional radiotherapy (QD) and the others received modified hyper-fractionated radiotherapy (BID). Only 7 patients in BID had tumor size <4 cm. All patients received high dose rate brachytherapy $(4\;Gy\times7\;or\;5\;Gy\times6)$. No Patient received concurrent chemotherapy during radiotherapy. Follow up period was ranging from 9 to 76 months (median 38). Results : The 5-year overall and disease free survival rates were $73.4\%\;and\;71.6\%$, respectively. Local recurrences occurred in $10\%$ of patients, and distant metastasis in $18.9\%$. There was a significant correlation between OS/DFS and tumor size $(<4cm;\;OS\;95.2\%,\;DFS\;91.4\%,\;\geq4cm;\;OS\;63.4\%,\;DFS\;63.4\%)$. Pretreatment SCC level was one of prognostic factors only in univariate analysis. Conclusion : With modified hyperfractionated radiotherapy, there was very low local recurrence rate $(6.6\%)$ and high 5-year overall and disease free survival rate $(75.4\%\;and\;70.5\%)$, which is comparable to results after concurrent chemoradiotherapy in bulky, locally advanced stage IIB uterine cervix cancer.

The advanced glycation endproducts receptor (AGER) is a multiligand signal transduction receptor. One of its ligands, S100b molecules activates vascular smooth muscle cells and endothelial cells via its receptor, thus triggering activation of signaling cascades and generation of cytokines and proinflammatory molecules. Ubiquitin-conjugating enzyme Ubc9 is an E2 conjugating enzyme that transfers the activated small ubiquitin-related modifier to protein substrates, and thus it plays a critical role in SUR-Mylation-mediated cellular pathways. Previous studies have shown that both AGE-R and Ubc9 play roles in diverse cellular signaling pathways. However, until recently, little attention has been paid to interactions between AGE-R and Ubc9. In this study, sequence database searches allowed us to identify a potential interaction motif between AGE-R and Ubc9. The subsequent biochemical and molecular biological analysis suggested that there may be specificity in AGE-R and Ubc9 complex signaling in atherosclerosis and cancer cells in a cell-type specific manner. Although the determinant for specificity in AGE-R and Ubc9 complex signaling in cancer cells and atherosclerosis is yet to be determined, this study provides the basis to develop a specific therapeutic application of AGE-R, SURM (small ubiquitin-related modifier)-1, and Ubc9 complex activation pathways in atherosclerosis, diabetes, cancer and inflammatory diseases.

Background: To determine rates of residual disease along with influencing factors in women with stage IA to IB1 cervical carcinoma after conization. Materials and Methods: A retrospective study was conducted of medical records of 198 stage IA to IB1 cervical carcinoma patients who had undergoing cervical conization followed by primary surgical treatment during 2006-2013. Independent factors correlating with residual carcinoma in subsequent surgical specimens were analyzed by stepwise regression analysis. Results: Mean age was 48.9 years. Cone specimens demonstrated free margins in 36 women (18.8%). In case of having disease at margin, high-grade cervical intraepithelial neoplasia (CIN) and carcinoma were evidenced in 58 and 97 women, respectively. Pathology of subsequent specimens revealed residual carcinoma in 78 women (39.4%), high-grade CIN or adenocarcinoma in situ (AIS) in 45 (22.7%), and no residual pathology in 75 (37.9%). Age more than 35 years, postmenopausal status, having symptoms, diseases or invasive lesions at conization margins or disease on endocervical aspect, and higher stage were significantly correlated with residual cancer in surgical treatment specimens. On regression analysis, postmenopause and stage were independent factors associated with residual carcinoma.Conclusions: Patient and tumor characteristics are predictive factors for residual cancer in the studied group of women.

Objectives: This study is conducted to identify the cancer incidence in Gwangju during the 5-year period from 1998 to 2002 and to assess the completeness and validity of the cancer registry data during this time period. Methods: All cases that had a diagnosis of invasive cancer (ICD-10 sites C00-C97) during the study period were retrieved from the records of the Gwangju Cancer Registry (GCR), which theoretically includes all the cancer cases in Gwangju. All the cases during the study period were analyzed by gender, age group and cancer sites. The completeness (mortality/incidence ratio and age-specific incidence curve) and validity (histologic verification, primary site unknown, age unknown and death certificate only) of the cancer registry in Gwangju were analyzed by gender, age group and cancer sites for the 5-year period. Results: The overall cancer incidence was higher in the males than in the females (age-standardized incidence rates (ASR) 299.8 and 172.4 per 100,000, respectively). In males, the most common cancer was stomach (ASR: 65.8), followed by liver (ASR: 50.5), bronchus and lung (ASR: 50.5), colo-rectum (ASR: 26.7), oesophagus (ASR: 10.6), and bladder (ASR: 10.3) in descending order. In females, the most common cancer was stomach (ASR: 26.8), followed by thyroid (ASR: 20.7), breast (ASR: 20.4), cervix uteri (ASR: 14.3), bronchus and lung (ASR: 13.0), liver (ASR: 10.7) and colo-rectum (ASR: 17.2) in descending order. The overall quality (completeness and validity) of the cancer registry was at the in 'good' level. Conclusions: These results will be useful in the overall context of planning and evaluating of cancer control activities in Gwangju.

Objectives: To describe the survival experience of cervix cancer patients in a screened rural population in India. Methods: Included 558 cervical cancer patients diagnosed in 2000-2013 in a cohort of 100,258 women invited for screening during 2000-2003. The primary end point was death from cervical cancer. We used the Kaplan-Meier method to estimate cumulative observed survival and Cox proportional hazards regression to assess the effect of patient characteristics on survival after diagnosis. Results: Of the 558 cases included, 143 (26%) and 114 (20%) were diagnosed in stages IA and IB respectively; 252 (45.2%) were dead, and 306 (54.8%) were alive at the last follow-up. The overall 5-year observed survival was 60.5%. The 5-year survival of stage IA patients was 95.1% and 5.3% for stage IV patients. All surgically treated stage IA patients, 94.1% of stage IB patients receiving intracavitary radiotherapy, 62% of stage IIB, 49% of stage III and 25% of stage IV patients receiving radiotherapy survived for 5 years. Conclusion: Higher 5-year survival in our study than elsewhere in India is due to the high proportion of early stage cancers detected by screening combined with adequate treatment, resulting into a favourable prognosis.

The State of Punjab has been in focus because of aperceived increasing rate of cancer. Both print and electronic media have created an impression that Punjab, especially the cotton belt of Malwa Region, has become a high incidence cancer region. Actually the increased number of cancer patients might be at least partly because of increasing population and heightened health awareness and reporting. The purpose of this study is to find out the pattern of cancer amongst patients registered in Mukh Mantri Punjab Cancer Rahat Kosh Scheme (MMPCRKS), under cancer registry at Rajindra Hospital Patiala from the various districts of Punjab. The study covers 500 cancer patients registered under MMPCRKS at Rajindra Hospital Patiala, for free cancer treatment. Information regarding age, gender, religion, method of diagnosis and affected sites was obtained. Results were analyzed statistically. Of the 500 patients, 65% were females and 35% were males. The most affected female age groups were 50-54 and 60-64; while males in the age groups of 65-69 and 60-64 had the highest risk. The leading cancers in females were breast followed by cervix and ovary where as in males they were were colon followed by esophagus and tongue. The commonest histological type was adenocarcinoma followed by squamous cell carcinoma. The increasing trend of cancer in Punjab is alarming. Since this study is a preliminary investigation, it could provide a leading role in prevention, treatment and future planning regarding cancer in Punjab.

Fragile histidine triad (FHIT) is a suppressor gene related to cervical cancer through CpG island hypermethylation. Folate is a water-soluble B-vitamin and an important cofactor in one-carbon metabolism. It may play an essential role in cervical lesions through effects on DNA methylation. The purpose of this study was to observe effects of folate and FHIT methylation and HPV 16 on cervical cancer progression. In this study, DNA methylation of FHIT, serum folate level and HPV16 status were measured using methylation-specific polymerase chain reaction (MSP), radioimmunoassay (RIA) and polymerase chain reaction (PCR), respectively, in 310 women with a diagnosis of normal cervix (NC, n=109), cervical intraepithelial neoplasia (CIN, n=101) and squamous cell carcinoma of the cervix (SCC, n=101). There were significant differences in HPV16 status (${\chi}^2=36.64$, P<0.001), CpG island methylation of FHIT (${\chi}^2=71.31$, P<0.001) and serum folate level (F=4.57, P=0.011) across the cervical histologic groups. Interaction analysis showed that the ORs only with FHIT methylation (OR=11.47) or only with HPV 16 positive (OR=4.63) or with serum folate level lower than 3.19ng/ml (OR=1.68) in SCC group were all higher than the control status of HPV 16 negative and FHIT unmethylation and serum folate level more than 3.19ng/ml (OR=1). The ORs only with HPV 16 positive (OR=2.58) or with serum folate level lower than 3.19ng/ml (OR=1.28) in CIN group were all higher than the control status, but the OR only with FHIT methylation (OR=0.53) in CIN group was lower than the control status. HPV 16 positivity was associated with a 7.60-fold increased risk of SCC with folate deficiency and with a 1.84-fold increased risk of CIN. The patients with FHIT methylation and folate deficiency or with FHIT methylation and HPV 16 positive were SCC or CIN, and the patients with HPV 16 positive and FHIT methylation and folate deficiency were all SCC. In conclusion, HPV 16 infection, FHIT methylation and folate deficiency might promote cervical cancer progression. This suggests that FHIT may be an effective target for prevention and treatment of cervical cancer.

Background: The proportion of aged Thais (${\geq}65$ years old) is expected to be 30% by 2030, leading to an increased number of elderly cancer cases. Older individuals have distinct patterns of cancer and treatment needs. We therefore conducted the present study of new cancer cases and trends to get a perspective on the elderly cancer situation in Northeast Thailand. Materials and Methods: All new elderly cancer cases (${\geq}65$ years) registered in the hospital-based cancer registry at the Faculty of Medicine, Srinagarind Hospital, Khon Kaen University during 1993-2012 were included in the study. Results: Elderly patients accounted for 31.6% of all cancer patients and new cancer cases in the older age group increased 46% from the first to second decades. The absolute number of oldest old (80+ years) doubled. The top three cancers in males were liver and bile duct, lung, and colorectal. In females, the three most common cancers were liver and bile duct, oral cavity, and cervix. Cancers with the highest percentages of increase were thyroid, prostate, and colorectal. Conclusions: Elderly cancer cases are increasing. Treatment modalities and palliative care for older populations are urgently needed.
