术后化疗疗程对早期上皮性卵巢癌预后的影响

目的：比较不同化疗疗程对早期卵巢上皮癌患者生存率和无瘤生存率的影响。方法180例患者按预后风险因素及化疗疗程分组,无瘤生存率及生存率采用Kaplan-Meier法估算,采用Log-Rank检验进行比较。结果≤4疗程（Ⅰ组）及﹥4疗程（Ⅱ组）5年总生存率（5-OS）、2年无瘤生存率（2-DFS）及5年无瘤生存率（5-DFS）分别为54.1%、51.6%、47.8%,48.3%、41.8%、40.0%;两组5-OS、2-DFS 及5-DFS 的差异均无统计学意义（P=0.926,P=0.713）。高危组和低危组患者5-OS、2-DFS 及5-DFS 分别为45.6%、84.7%,38.5%、93.5%,32.9%、77.5%;两组5-OS、2-DFS及5-DFS差异有统计学意义（P均=0.000）。高危组中≤4疗程（A1组）及﹥4疗程（A2组）5-OS、2-DFS及5-DFS分别为39.6%、48.5%,26.8%、43.7%,26.8%、36.0%;两组5-OS差异无统计学意义（P=0.314）,A1组2-DFS及5-DFS均低于A2组（P=0.011）。低危组中≤4疗程化疗及﹥4疗程5-OS、2-DFS及5-DFS分别为85.1%、83.3%,95.0%、90.9%,77.7%、77.9%;两组5-OS、2-DFS及5-DFS差异无统计学意义（P＞0.5）。结论高危组早期上皮性卵巢癌患者术后予大于4疗程化疗可提高其无瘤生存率。     

Combined Therapy with Transarterial Chemoembolization and Radiofrequency Ablation for Hepatocellular Carcinoma: Does the Degree of Ethiodized Oil Accumulation within the Tumor Affect the Therapeutic Efficacy?

Purpose

To evaluate the effects of the degree of ethiodized oil accumulation achieved by transarterial chemoembolization followed by radiofrequency (RF) ablation on the treatment efficacy for a single intermediate-sized hepatocellular carcinoma (HCC).

Expression of Pituitary Tumor Transforming Gene 1 is an Independent Factor of Poor Prognosis in Localized or Locally Advanced Prostate Cancer Cases Receiving Hormone Therapy

We investigated the prognostic value of pituitary tumor transforming gene 1 (PTTG1) expression according toclinicopathological features among localized or locally advanced prostate cancer cases receiving hormone therapy.A retrospective study involved 64 patients receiving combined androgen blockade treatment was performed.PTTG1 expression was determined by immunohistochemical staining using initial needle biopsy specimensfor diagnosis. Associations of PTTG1 with various clinicopathological features and disease-free survival wereexamined via uni- and multivariate analyses. No association between PTTG1 expression and clinical T stage,Gleason score, pretreatment PSA levels, risk groups was found (p =0.682, 0.184, 0.487, 0.571, respectively).Univariate analysis revealed that increased PTTG1 expression, T3 stage and high risk group were associatedwith increased risk of disease progression (p =0.000, 0.042, and 0.001), and high PSA level had a tendency topredict disease progression (p =0.056). Cox hazard ratio analysis showed that PTTG1 low expression (p =0.002),PTTG1 high expression (p =0.000) and high risk group (p =0.0147) were significantly related to decreased diseasefreesurvival. In conclusion, PTTG1 expression determined by immunohistochemical staining in needle biopsyspecimens for diagnosis is a negative prognostic factor for progression in localized or locally advanced prostatecancer receiving hormone therapy.     

Prognostic impact of neoadjuvant chemotherapy induced neutropenia on operable breast cancer

Objective To evaluate the relationship between neoadjuvant chemotherapy (combination of taxanes and anthracyclines) induced-neutropenia and the efficacy of neoadjuvant chemotherapy and longterm survival in operable breast cancer patients. Methods Two hundred and eleven patients received 4 cycles of neoadjuvant chemotherapy     

Simultaneous measurement of the viability,aggregation, and live and dead adherence of Streptococcus crista,Streptococcus mutans and Actinobacillus actinomycetemcomitans in human saliva in relation to indices of caries,dental plaque and periodontal disease

Salivary proteins have multiple functions and many share similar functions, which may be why it has been difficult to relate variations in their concentrations to oral health and ecology. An alternative is to focus on variations in the major functions of saliva. An hydroxyapatite-coated microplate model has been developed that simultaneously measures saliva-promoted bacterial viability, bacterial aggregation, and live and dead bacterial adherence, while simulating oral temperature and shearing forces from swallowing. That model was applied to resting whole and stimulated parotid saliva from 149 individuals, using representative strains of Streptococcus crista, S. mutans, and Actinobacillus actinomycetemcomitans. Two major factors were defined by multivariate analysis (this was successful only for whole-saliva). One factor was correlated with aggregation, live adherence and dead adherence for all three strains; the other was correlated with total viability of all three strains. Participants were grouped <25th percentile and >75th percentile for each factor. Those groups were compared for clinical indices of oral health. Caries scores were significantly lower in those with high scores for aggregation-adherence, regardless of whether total viability scores were low or high. Live bacteria always predominated on surfaces when live and dead adherence scores were expressed as ratios. However, participants with high scores for aggregation-adherence showed significantly more dead adherent bacteria than those with low scores (these ratios were uncorrelated with total viability). This finding may indicate that extreme differences in the ability to kill bacteria on surfaces can influence caries risk.     

Does the Increased Rate of Serous Component (≤25% vs. >25%) Increase Recurrence in Endometrial Cancer With Serous Plus Endometrioid Histology?

Objective

The aim of the study is to investigate the effect of increasing serous component ratio on survival in endometrium cancer patients with serous plus endometrioid histology.
