Manual Lymphatic Drainage and Active Exercise Effects on Lymphatic Function Do Not Translate Into Morbidities in Women Who Underwent Breast Cancer Surgery.

OBJECTIVE: To evaluate manual lymphatic drainage (MLD) and active exercise effects on lymphatic alterations of the upper limb (UL), range of motion (ROM) of shoulder, and scar complications after breast cancer surgery. DESIGN: Clinical trial. SETTING: Health care center. PARTICIPANTS: Women (N=105) undergoing radical breast cancer surgery who were matched for staging, age, and body mass index. INTERVENTIONS: Women (n=52) were submitted to MLD and 53 to active exercises for UL for 1 month and followed up. MAIN OUTCOME MEASURES: Shoulder ROM, surgical wound inspection and palpation, UL circumference measurements, and lymphoscintigraphy were performed in preoperative and postoperative periods. RESULTS: There was no significant difference between groups with regard to wound healing complications, ROM, and UL circumferences. After surgery, 25 (48.1%) of the MLD group and 19 (35.8%) of the active exercise group showed worsening in radiopharmaceutical uptake velocity, whereas 9 (17.3%) of the MLD group and 11 (20.8%) of the active exercise group showed improved velocity (P=.445). With regard to uptake intensity, 27 (51.9%) of the MLD group and 21 (39.6%) of the active exercise group showed worsening whereas 7 (13.5%) of the MLD group and 7 (13.2%) of the active exercise group showed some improvement (P=.391). The presence of collateral circulation was similar in both groups at both time points evaluated. The active exercise group had a significant increase in postoperative liver absorption (P=.005), and the MLD group had a significant increase in postoperative dermal backflow (P=.024). CONCLUSIONS: MLD and active exercise effects are equivalent with regard to morbidity. Minor changes in lymphatic function associated with either MLD or active exercises were not related to patients' symptoms or signs.

High Expression of SOD2 Protein Is a Strong Prognostic Factor for Stage IIIB Squamous Cell Cervical Carcinoma.

High superoxide dismutase 2 (SOD2) expression is associated with a poor prognosis at many cancer sites, the presence of metastases, and more advanced cervical cancer. This study aims to determine whether SOD2 protein expression is associated with the prognosis of stage IIIB cervical carcinoma. METHODS: sixty-three patients with stage IIIB squamous cell cervical carcinoma were included. The evaluation of SOD2 expression by immunohistochemistry was based on a positive cell ratio score and the staining intensity score. Taking disease recurrence and death as endpoints, receiver operating characteristic curves were used to discriminate between high and low SOD2 expression. RESULTS: high SOD2 expression was associated with recurrence (p = 0.001), distant recurrence (p = 0.002), and death (p = 0.005). A multivariate analysis showed that patients with high SOD2 expression had a threefold increased risk for recurrence (HR = 3.16; 1.33-7.51) and death (HR = 2.98; 1.20-7.40) compared with patients who had low SOD2 expression. Patients with high SOD2 expression had shorter disease-free survival (p = 0.001) and overall survival (p = 0.003) than patients with low SOD2 expression. CONCLUSION: high SOD2 expression is a strong prognostic factor for stage IIIB squamous cell carcinoma of the cervix and could be used as a prognostic marker in women with cervical carcinoma.
