Risk factors for lower limb lymphedema after lymph node dissection in patients with ovarian and uterine carcinoma

<p>Abstract</p> <p>Background</p> <p>Lymph node dissection has proven prognostic benefits for patients with ovarian or uterine carcinoma; however, one of the complications associated with this procedure is lymphedema. We aimed to identify the factors that are associated with the occurrence of lymphedema after lymph node dissection for the treatment of ovarian or uterine carcinoma.</p> <p>Methods</p> <p>A total of 694 patients with histologically confirmed ovarian (135 patients) or uterine cancer (258 with cervical cancer, 301 with endometrial cancer) who underwent lymph node dissection were studied retrospectively. Logistic regression analyses were used to identify the risk factors associated with occurrence of lymphedema.</p> <p>Results</p> <p>Among ovarian and uterine cancer patients who underwent pelvic lymph node dissection, post-operative radiotherapy (odds ratio: 1.79; 95% confidence interval: 1.20–2.67; p = 0.006) was statistically significantly associated with occurrence of lymphedema.</p> <p>Conclusion</p> <p>There was no relationship between any surgical procedure and occurrence of lymphedema among patients undergoing pelvic lymphadenectomy. Our findings are supported by a sound biological rationale because they suggest that limb lymphedema is caused by pelvic lymph node dissection.</p

気管支喘息の臨床分類とその細胞性および液性因子の特徴

Characteristics of each asthma type classified by clinical symptoms and　findings were studied in 72 patients with bronchial asthma. 1. Ventilatory function tests showed that the values of % MMF, % V(50) and % V(25) were significantly lower in patients with bronchiolar obstruction (type II) compared to the values of those with simple bronchoconstriction type (type Ia) and those with bronchoconstriction + hypersecretion (type Ib). 2. The proportion of neutrophils in bronchoalveolar lavage (BAL) fluid was significantly higher in type II than in type Ia and type Ib. Several　patients with type Ib showed higher proportion of BAL eosinophils. 3. The release of LTC(4) from leucocytes was significantly lower in type II compared with type Ia and type Ib. There was no significant difference in the release of histamine and LTB(4) among the three asthma types.気管支喘息72例を対象に,その臨床病態の特徴を,気道炎症性の細胞および化学伝達物質の観察により検討した｡1.気道反応の特徴を換気機能の面から検討すると,II細気管支閉塞型において,MMF,V(50)やV(25)などの小ないし細気管支領域の換気障害を示すパラメーターの値は,Ia型,Ib型に比べ 有意の低下を示した｡2.気道細胞反応では,II型において,他の臨床病型に比べ,BAL液中好中球の出現頻度の有意の増加が観察された(Ia, p<0.001 ; Ib, p<0.01)｡好酸球の出現頻度は,Ib過分泌型において著しい増加傾向を示す症例が見られたが,その平均出現頻度には3病型間に有意の差は見られなかった｡3.好中球からのメジェー夕ー遊離では,ヒスタミン遊離は,Ia単純性気管支撃縮型において最も高い値が示されたが,推計学的には3病型間に有意の差は見られなかった｡ロイコトリエンC(4)では,Ia型においてII型に比べ有意に高い遊離が観察された(p<0.05)｡ロイコトリエンB(4)遊離には,3病型間に差は見られなかった

Cyclin-dependent kinase-specific activity predicts the prognosis of stage I and stage II non-small cell lung cancer

BACKGROUND: Lung cancer is one of the leading causes of cancer death worldwide. Even with complete resection, the prognosis of early-stage non-small cell lung cancer is poor due to local and distant recurrence, and it remains unclear which biomarkers are clinically useful for predicting recurrence or for determining the efficacy of chemotherapy. Recently, several lines of evidence have indicated that the enzymatic activity of cyclin-dependent kinases could be a clinically relevant prognostic marker for some cancers. We investigated whether the specific activity of cyclin-dependent kinases 1 and 2 could predict recurrence or death in early non-small cell lung cancer patients. METHODS: Patients with newly diagnosed, pathologically confirmed non-small cell lung cancer were entered into this blinded cohort study. The activity of cyclin-dependent kinases was determined in 171 samples by the C2P® assay, and the results were subjected to statistical analysis with recurrence or death as a clinical outcome. RESULTS: The Cox proportional hazards model revealed that the activity of cyclin-dependent kinase 1, but not 2, was a predictor of recurrence, independent of sex, age, and stage. By contrast, cyclin-dependent kinase 2 activity was a predictor of death, independent of sex and stage. CONCLUSION: This study suggested the possible clinical use of cyclin-dependent kinase 1 as a predictor of recurrence and cyclin-dependent kinase 2 as a predictor of overall survival in early-stage non-small cell lung cancer. Thus, a combination of activity of cyclin-dependent kinases 1 and 2 is useful in decision-making regarding treatment strategies for non-small cell lung cancer after surgery.
