PURPOSE: to evaluate the efficacy of a physical exercise protocol in the recovery of shoulder movement in women who underwent complete axillary lymph node dissection due to breast carcinoma, comparing free and restricted amplitude movements. METHODS: 59 women who underwent complete axillary lymph node dissection associated with modified mastectomy (46) or quadrantectomy (13) were included in this clinical, prospective and randomized study. On the first day after surgery 30 women were randomized to do the shoulder movement with free amplitude and 29 women had this amplitude restricted to 90º in the first 15 days. Nineteen exercises were done, three sessions per week, for six weeks. Mean (± standard error) deficits of shoulder flexion and abduction were compared, as well as gross and adjusted incidence rates of seroma and dehiscence. RESULTS: 42 days after surgery, flexion and abduction means were similar in the two groups. Both presented a mean flexion deficit (17.2º and 21.6º, respectively), and abduction deficit (19.7º and 26.6º, respectively). The incidence rates of seroma and dehiscence were neither related to exercise nor to the type of surgery, time of drain permanence, number of dissected or compromised lymph nodes, age or obesity. CONCLUSION: early physiotherapy with free movement of the women's shoulder was associated neither with functional capacity nor with postsurgical complications.

Purpose: to evaluate the relationdhip between preservation of the intercostobrachial nerve and pain sensitivity of the arm, total time of the surgery, and number of dissected nodes in patients submitted to axillary lymphadenectomy due to breast cancer. Methods: an intervention, prospective, randomized and double-blind study was performed on 85 patients assisted at the State University of Campinas, Brazil, from January 1999 to July 2000. The patients were divided into two groups, according to the intention of preserving or not the intercostobrachial nerve. The surgeries were performed by the same researchers, utilizing the same technique. The postoperative evaluations were performed within 2 days, 40 days and after 3 months. The pain sensitivity of the arm was evaluated through a specific questionnaire (subjective evaluation) and through a neurological physical examination (objective evaluation). Results: the surgical technique was applied to all patients and the preservation of the intercostobrachial nerve was related to a significant decrease in the alterations of pain sensitivity of the arm, both by the subjective and objective evaluations. After three months, in the subjective evaluation, 61% of the patients were asymptomatic in the intercostobrachial nerve preservation group and 28.6% in the nerve section group (p<0.01). By the objective evaluation, 53.7% of the patients presented normal neurological examination in the intercostobrachial nerve preservation group and 16.7% in the nerve section group (p<0.01). No significant difference was observed regarding total time of surgery (p=0.76) and number of dissected nodes between the two evaluated groups (p=0.59). Conclusions: these data show that the preservation of the intercostobrachial nerve is feasible and leads to a significant decrease in the alterations of pain sensitivity of the arm, without interfering in the total time of surgery and the number of dissected nodes.

, , , , , To evaluate the number of patients with early-stage breast cancer who could benefit from the omission of axillary surgery following the application of the Alliance for Clinical Trials in Oncology (ACOSOG) Z0011 trial criteria.
A retrospective cohort study conducted in the Hospital da Mulher da Universidade Estadual de Campinas. The study population included 384 women diagnosed with early-stage invasive breast cancer, clinically negative axilla, treated with breast-conserving surgery and sentinel lymph node biopsy, radiation therapy, chemotherapy and/or endocrine therapy, from January 2005 to December 2010. The ACOSOG Z0011 trial criteria were applied to this population and a statistical analysis was performed to make a comparison between populations.
A total of 384 patients underwent breast-conserving surgery and sentinel lymph node biopsy. Of the total number of patients, 86 women underwent axillary lymph node dissection for metastatic sentinel lymph nodes (SNLs). One patient underwent axillary node dissection due to a suspicious SLN intraoperatively, thus, she was excluded fromthe study. Among these patients, 82/86 (95.3%) had one to two involved sentinel lymph nodes andmet the criteria for the ACOSOG Z0011 trial with the omission of axillary lymph node dissection. Among the 82 eligible women, there were only 13 cases (15.9%) of lymphovascular invasion and 62 cases (75.6%) of tumors measuring up to 2 cm in diameter (T1).
The ACOSOG Z0011 trial criteria can be applied to a select group of SLNpositive patients, reducing the costs and morbidities of breast cancer surgery.

Objective: to compare mammographic density changes, case by case, according to image digitization in three consecutive evaluations of users or nonusers of hormonal replacement therapy (HRT). Methods: 59 postmenopausal women were evaluated, 43 being users of cyclic or continuous estro-progestin hormonal replacement therapy, and 16 nonusers. The criteria of inclusion were: amenorrhea for at least 12 months, a normal mammographic examination at the beginning of the HRT (users) or the clinical follow-up without HRT (nonusers), at two incidences (mediolateral and craniocaudal). The following variables were used for the evaluation of mammary density: initial change - the difference between the first mammography after HRT performed in 12 ± 3 months and the mammography performed before HRT-and final change - the difference between the second mammography after HRT performed in 24 ± 3 months and the mammography performed before HRT. Wilcoxon and c² tests were used in order to evaluate the differences in mammographic density changes. Results: more than half (56.3%) of the women, HRT users with initial increase in mammographic density remained with the increase after the final evaluation. This finding was not significant (p=0.617). In the same group, the initial nonincrease was significantly associated with the final nonincrease (p=0.017). Among the nonusers, all breasts that were not totally fat at the initial evaluation presented a mammographic density decrease at the final evaluation. Conclusions: the majority of HRT users presenting mammographic density increase at the first evaluation, after approximately one year of use, remained with the increase at a second evaluation. After some time, the nonusers tended to present a significant mammographic density decrease (p=0.003).

Purpose: to study the association between the evaluation or not of the male partner and relapses in women treated for HPV lesions. Methods: a reconstituted cohort study with 144 women with HPV lesions and whose partners had been evaluated, compared with 288 women whose partners had not been examined, controlled regarding date of attendance, age, lesion degree and treatment, attended between July 1993 and March 2000. We evaluated similarity between the groups, the association between the evaluation or not of the partners or the diagnosis of lesions with the occurrence and relapse lesion degree in the women and the disease-free interval (DFI). Results: the groups were similar regarding the control variables. Relapses occurred in 9.0 % of the women whose partners had been evaluated and in 5.9% of those whose partners had not been evaluated (p=0.23). When lesions were diagnosed in the men, 12.5% of their partners had relapses, against 7.3% of the women whose partners had no lesions (p=0.23), but there was no correlation with the relapse lesion degree and DFI. When the men reported a time of monogamous conjugal relationship <12 months, we observed 14.9% relapses in women, against 6.2% for the women whose partners reported a longer time (p=0.08). Conclusions: evaluation of the man did not decrease the relapse risk of HPV lesions in his partner. The presence of lesions in the male partners did not correlate with the occurrence and relapse degree in women and DFI. This study does not support the hypothesis that nonevaluated men would be an important cause of relapses in their partners.

Purpose: to evaluate risk factors and papillomavirus (HPV) associated lesions in male partners of women with genital intraepithelial neoplasia. Patients and Methods: three hundred and thirty-seven men were evaluated by urethral cytology, peniscopy, and biopsy, if necessary. We analyzed the results and the relations to age, educational level, smoking, contact time with the present partner, age at first intercourse, number of partners, previous sexually transmitted diseases (STD), circumcision, peniscopic findings, and female lesion grade. Results: peniscopy was positive in 144 (42,7%) and HPV infection was diagnosed in 105 (31,2%). Smoking, contact time with the present partner up to 6 months, and more than one previous sexual partner were associated with HPV lesions (p<0,05). The urethral cytology was suspect in 4,2% and smoking, positive peniscopy or biopsy and partners of women with high-grade lesion (p<0,05) were associated with the diagnosis. 72.1% of 229 biopsies were positive, independently of the peniscopic findings and women's lesion grade. Conclusions: HPV infection was diagnosed in 31.2% and was associated with smoking, contact time with the present partner up to 6 months and more than one previous sexual partner, but not with the female lesion grade, educationa level, previous STD, circumcision and peniscopic findings.

PURPOSE: to evaluate the relationship between epidemiologic, anthropometric, reproductive and hormonal factors and mammographic density in postmenopausal women. METHODS: this is a retrospective, cross-sectional study, including 144 women aged 45 years or more, with at least 12 months of amenorrhea and who were non users of hormone replacement therapy during the last six months. Medical charts were reviewed to evaluate age, weight, body mass index (BMI), parity, age at menarche, age at menopause and levels of estradiol, follicle stimulating (FSH) and luteinizing hormones. Mammograms were analyzed by two blinded investigators. The films were taken in the craniocaudal and mediolateral views and mammography was classified as dense and nondense, according to the Wolfe criteria. For statistical analysis, the frequency, median, minimum and maximum values, the Wilcoxon test and the odds ratio were used. Multiple logistic regression was performed, using the stepwise selection, with a 5% significance level. RESULTS: the frequency of dense breasts was 45%. Women with dense breasts were of lower weight (60.5 vs. 71.9 kg - p<0.01), had a lower BMI (25.9 vs 31.0 kg/m² - p<0.01), a shorter time since onset of menopause (6.0 vs 10 years - p<0.01) and higher levels of FSH (75.2 vs 60.3 mU/mL - p<0.01). The probability of having dense breasts decreased in women whose weight was 67 kg or more (OR = 4.0, CI 95% = 1.50-10.66), BMI was higher than 30 kg/m² (OR = 6.69, CI 95% = 1.67-36.81), time since onset of menopause was superior or equal to seven years (OR = 2.05, CI 95% = 1.05-3.99) and FSH levels were lower than 134.8 mU/mL. CONCLUSION: weight, BMI, parity, time since menopause and FSH levels were significantly associated with mammographic density patterns.

PURPOSE: To explore the relationship between morphological characteristics and histologic localization of metastasis within sentinel lymph nodes (SLN) and axillary spread in women with breast cancer. METHODS: We selected 119 patients with positive SLN submitted to complete axillary lymph node dissection from July 2002 to March 2007. We retrieved the age of patients and the primary tumor size. In the primary tumor, we evaluated histologic and nuclear grade, and peritumoral vascular invasion (PVI). In SLNs we evaluated the size of metastasis, their localization in the lymph node, number of foci, number of involved lymph nodes, and extranodal extension. RESULTS: Fifty-one (42.8%) patients had confirmed additional metastasis in non-sentinel lymph nodes (NLSN). High histologic grade, PVI, intraparenchymatous metastasis, extranodal neoplastic extension and size of metastasis were associated with positive NLSN. SLN metastasis affecting the capsule were associated to low risk incidence of additional metastasis. After multivariate analysis, PVI and metastasis size in the SLN remained as the most important risk factors for additional metastasis. CONCLUSIONS:The risk of additional involvement of NSLN is higher in patients with PVI and it increases progressively according the histologic localization in the lymph node, from capsule, where the afferent lymphatic channel arrives, to the opposite side of capsule promoting the extranodal extension. Size of metastasis greater than 6.0 mm presents higher risk of additional lymph node metastasis.
