ABSTRACT

Background: Tumors of the nervous system are the second most common childhood cancer after leukemia. The diagnosis of CNS tumors is challenging due to non-specific symptoms in children which mimic other less serious illness.Methods: This was a retrospective analysis of case records of patients from 0-18 years of age, who were diagnosed with CNS tumors for a period of 7 years.Results: Out of total 64 patients included in this study, 32 were females and 24 were males. The mean age was 13.2 years. The most common clinical presentation in patients with brain tumors was headache (92.3%) followed by visual symptoms in the form of blurring or loss of vision (42.3%) and swaying while walking (32.6%). The overall mean symptom interval for all patients was 274.8 days (approx. 9 months) ranging from 7-1820 days. In the present study out of total 64 patients, 54 were brain tumors (35 supratentorial and 19 infratentorial) and 10 were spinal tumors. The most common tumor location was cerebellum (21.8%) followed by cerebral cortex, spine and sellar area. Based on histopathology the most common tumor type in our study was astrocytoma. There was no significant correlation of symptom interval with age and gender but was significantly associated with location and tumor grade.Conclusions: Early referral to centers with appropriate facilities will help, as many pediatric CNS tumors are low grade with better survival.

ABSTRACT

PURPOSE: The purpose of this study was to investigate the non-inferiority of omitting radiotherapy (RT) after breast-conserving surgery (BCS) for hormone receptor (HR)‒positive T1N0 breast cancer in elderly women. MATERIALS AND METHODS: From 2004 to 2014, HR-positive T1N0 breast cancer patients aged 50 years or older and receiving BCS were retrieved from the Surveillance, Epidemiology, and End RESULTS: 18 database. After propensity score matching between the no-RT and RT groups, univariate and multivariate analyses were performed. Identified prognostic factors were used to stratify the risk groups. In each risk group, 10-year cancer-specific survival (CSS) rates were compared between the no-RT and RT groups. RESULTS: After propensity score matching, the numbers of patients in the no-RT and RT groups were both 18,586. For patients who satisfied both a tumor size of 1-10 mm and a tumor grade of 1-2, omitting RT did not decrease the CSS rate at any age group, ranging from ≥ 50 to ≥ 85 years; for patients aged ≥ 50 years, the 10-year CSS rates in the no-RT and RT groups were 97.2% and 96.8%, respectively (adjusted hazard ratio, 0.862; p=0.312). However, for patients with a tumor size of 11-20 mm or tumor grade of 3-4, RT significantly increased the CSS rate irrespective of age. CONCLUSION: RT after BCS for HR-positive T1N0 breast cancer in elderly women might be omitted without causing a decrease in the CSS rate, but only in patients who satisfy both a small tumor size (≤ 10 mm) and low tumor grade (1-2).

ABSTRACT

OBJECTIVE: The purpose of this study is to investigate the incidence of lymph node metastasis in early endometrial cancer patients and to evaluate preoperative clinicopathological factors predicting lymph node metastasis. METHODS: We identified 142 patients with endometrial cancer between January 2000 and February 2013. All patients demonstrated endometrioid adenocarcinoma with grade 1 or 2 on preoperative endometrial biopsy. Preoperative magnetic resonance imaging showed that tumors were confined to the uterine corpus with superficial myometrial invasion (less than 50%), and there were no lymph nodes enlargements. All patients had complete staging procedures and were surgically staged according to the 2009 FIGO (International Federation of Gynecology and Obstetrics) staging system. Clinical and pathological data were obtained from medical records and statistically analyzed. RESULTS: Of the 142 patients, 127 patients (89.4%) presented with stage 1A, 8 (5.6%) with stage IB, 3 (2.1%) with stage II, and 4 (2.8%) with stage III disease. Three patients (2.1%) had lymph node metastasis-2 IIIC1 and 1 IIIC2 disease. Age, preoperative tumor grade, and myometrial invasion less than 50% on preoperative MRI were not associated with lymph node metastasis. A high preoperative serum CA-125 level (>35 IU/mL) was a statistically significant factor for predicting lymph node metastasis on univariate and multivariate analyses. Lymph node metastasis was only found in patients with preoperative grade 2 tumors or a high serum CA-125 level. CONCLUSION: Preoperative tumor grade and serum CA-125 level can predict lymph node metastasis in apparent early endometrial cancer patients.

ABSTRACT

AIM: The study objectives were evaluation of clinicopathological characteristics, correlations between the preoperative and postoperative tumor grades, and their implications on lymph node metastasis. MATERIALS AND METHODS: We conducted a retrospective descriptive study of 131 cases of endometrial cancer examined and treated at a tertiary regional cancer institute between the years 2003 and 2009. We reviewed the oncology database as well as the clinical records and surgico‑pathological registry of all these patients. STATISTICAL METHODS USED: All the summary measure computation and Chi‑square test for comparing more than one proportion was done in spreadsheet (Excel). RESULTS: The multiparity association with endometrial cancer was commonly seen 113/131 (86.2%). Twelve (9.7%) patients preoperatively diagnosed as Grade 1 tumors upgraded to Grade 3 changes in postoperative specimens and six of these 12 patients (50%) had lymph node metastasis. A total of 14/131 (10.6%) cases had lymph nodes metastasis. CONCLUSIONS: There is a poor correlation between the preoperative and the postoperative tumor grades. Routine pelvic lymphadenectomy may be a valuable method in low‑risk cases and para‑aortic lymphadenectomy may be limited to high‑risk endometrial cancers.

ABSTRACT

Background: The goal of this study was to analyze the correlation of oxidative stress in human glioma cells with tumor grade in order to explore the role of oxidative stress as a marker in determining the tumor progression. Methods: Samples were 21 brain tumors and 5 normal brain tissues from glioma patients. Oxidative stress was analyzed by measuring malondialdehyde (MDA), carbonyl and 8-hydroxy-2’-deoxyguanosine (8-OhdG). Additionaly, we analyzed MnSOD expression by measuring the MnSOD mRNA using real time RT-PCR and MnSOD enzyme activity using RanSOD kit. Tumor grade was determined by histopathologic examination. Data was statistically analyzed using t-test and Pearson correlation. Results: Levels of MDA, carbonyl and 8-OHdG reflecting oxidative stress in glioma cells were significantly higher than in normal brain tissue. The MDA and carbonyl levels were significantly correlated with tumor grade. Relative expression of MnSOD mRNA and specific enzyme activity in glioma cells were significantly higher than in normal brain cells. The relative expression of MnSOD mRNA increased significantly in accordance with the tumor grade. Surprisingly, MnSOD specific activity was significantly lower in high grade than in low grade glioma indicating a discrepancy between mRNA synthesis and its enzyme specific activity. Furthermore, there was a positive correlation between MnSOD mRNA and MDA levels. Conclusion: The high level of oxidative damage in human glioma cells was significantly correlated with tumor grade. The high level of MnSOD expression in human glioma cells was correlated with the high level of oxidative damage.

ABSTRACT

The objective of this study is to assess the relation between serum prostate specific antigen (PSA), clinical tumor stage, tumor grade, and bone scan result in an attempt to seek the ability of serum PSA to predict bone metastases in newly diagnosed prostate cancer patients. A retrospective analysis was conducted on clinical files of prostate cancer patients which were diagnosed in our institutions between January 1995 and December 2003. Patients on which initial serum PSA were obtained after urethral manipulation or after receiving therapy were excluded. The results of bone scans were related to levels of serum PSA, clinical tumor stage, and tumor grade. Of 103 patients who were included in this investigation, 61 patients (59.2%) had a positive bone scan and 42 patients (40.8%) had a negative bone scan with mean PSA value 471.13 ± 853.34 ng/ml and 61.00 ± 124.47 ng/ml respectively (p < 0.05). The risk of having a positive bone scan increased with advancing serum PSA levels, clinical tumor stage, and tumor grade (p < 0.05). Using receiver operating characteristic curves, PSA had the best correlation with bone scan results (the area under curve was 0.812). Bone scan results were predicted best by the combination of serum PSA, clinical tumor stage, and tumor grade. Bone scans were positive in 5 of 19 patients with PSA level < 10 ng/ml. None of 8 patients with PSA levels < 10 ng/ml, clinical tumor stage T1 or 2 and tumor grade 1 or 2 had a positive bone scan. In conclusion, we suggest that routine bone scan examination may not be necessary in patients with newly diagnosed, untreated prostate cancer, who have serum PSA level < 10 ng/ml with clinical tumor stage T1 or 2 and tumor grade 1 or 2.

ABSTRACT

Transforming growth factor-beta (TGF-beta), a pleiotropic growth factor, is a potent inhibitor of cellular proliferation in cells of epithelial origin. Recently, it has been suggested that a loss of sensitivity to TGF-beta through a loss of expression of TGF-beta receptors T beta R-I and T beta R-II--is associated with tumor initiation and progression. Therefore, to investigate the relationship between TGF-beta receptors expression and carcinogenesis of bladder TCC, this study examined the expression of T beta R-I and T beta R-II in 46 bladder TCC patients using immunohistochemistry. Since histopathological grade is a widely accepted marker of prognosis, the results were compared in relation to the three grades of bladder TCC. The results demonstrated that the loss of TGF-beta receptors expression is associated with increasing histopathological grades of bladder TCC. Specifically, both T beta R-I and T beta R-II were readily detected in all 10 normal bladder mucosa specimens. Likewise, all 6 specimens of grade I TCC samples expressed high levels of both TGF-beta receptors. However, among grade II TCC samples, T beta R-I and T beta R-II were detected in 78% and 89%, respectively: among grade III TCC samples, T beta R-I and T beta R-II were detected in 45% and 41%, respectively. These results suggested that loss of sensitivity to TGF-beta may play a role in the progression of TCC from low to high grade disease.

ABSTRACT

The preoperative serum level of tumor marker CA 125 has served as rough orientation in making the distinction between a benign and a malignant adnexal mass or as a reference for monitoring the success of therapy. But there were some reports suggesting that the stage of the disease and tumor grade, which are known to be the independent prognostic factors in ovarian cancer patients, may exert an influence on the preoperative CA 125 level. In this retrospective study we analysed the significance of preoperative serum CA 125 level with respect to tumor grade and tumor stage. Between June, 1989 and January, 1997, 82 patients with epithelial ovarian cancer managed at Asan Medical Center were evaluated, in whom serum level CA 125 were measured preoperatively. Tumor grade bears no meaningful influence on the preoperative CA 125 level, and also the correlation is low and statistically insignificant (r=0.12, p=0.29 in all stages; r=0.01, p=0.97 in stage I; r=-0.09, p=0.83 in stage II; r=0.06, p=0.72 in stage III; r=0.25, p=0.41 in stage IV). There was no significant effect of FIGO stage on preoperative CA 125 level (r=0.21, p=0.06 in all grades; r=0.32, p=0.10 in G1; r=0.08, p=0.74 in G2; r=0.17, p=0.30 in G3). However, we found a significant correlation between FIGO stage and tumor grade (r=0.45, p<0.01). In conclusion, our data suggests that both tumor grade and FIGO stage have no significant effect on preoperative serum CA 125 level.

ABSTRACT

E-cadherin (E-CD), a Ca2+ -dependent adhesion molecule, plays a major role in the maintenance of intercellular junctions in normal epithelial cells in most organs. Recently, a correlation has been observed between a loss of E-CD and increased invasiveness of neoplastic cells. In this study, E-CD expression in the breast carcinoma was investigated using monoclonal antibody, anti-E-CD by immunohistochemical method. Expression of E-CD were evaluated in 57 breast carcinomas and correlated with their tumor grade, lymph node involvement, and hormonal receptor status. Histological types included in this study were 54 invasive ductal carcinomas (IDCs) of otherwise not specified and 3 invasive lobular carcinomas. Cases of histologic grade I IDC were 6, grade II 30, and grade III 18. Of 54 IDCs 39 (72.2%) showed moderate to strong linear staining at the cell borders regardless of their histologic grade, status of lymph node metastasis, and status of hormone receptor. Staining intensity of E-CD was reduced in 54 cases (83%) of IDC when compared with that of normal or benign breast lesions (P<0.01). All seven cases of intraductal carcinoma, which were included in 54 IDCs showed one or two grade reduced expression of E-CD than that of infiltrative lesions. Three invasive lobular carcinomas showed strong (1 case), moderate (1 case), and negative reactivity (1 case). The data indicated that loss of E-CD expression is a crucial event in the development of breast carcinoma.
