, , , , , , Neoadjuvant chemotherapy (NACT) has become the standard of care for patients with triple-negative breast cancer (TNBC) with tumors > 1 cm or positive axillary nodes. Pathologic complete response (pCR) has been used as an endpoint to select patients for treatment scaling. This study aimed to examine the benefit of adding adjuvant capecitabine for TNBC patients who did not achieve pCR after standard NACT in a real-world scenario.
This retrospective cohort study included all patients with TNBC who underwent NACT between 2010 and 2020. Clinicopathological data were obtained from the patient records. Univariate and multivariate analyses were conducted at the 5 years follow-up period.
We included 153 patients, more than half of whom had stage III (58.2%) and high-grade tumors (60.8%). The overall pCR rate was 34.6%, and 41% of the patients with residual disease received adjuvant capecitabine. Disease-specific survival (DSS) among the patients who achieved pCR was significantly higher (p<0.0001). Residual disease after NACT was associated with detrimental effects on DSS. In this cohort, we did not observe any survival benefit of adding adjuvant capecitabine for patients with TNBC subjected to NACT who did not achieve pCR (p=0.52).
Our study failed to demonstrate a survival benefit of extended capecitabine therapy in patients with TNBC with residual disease after NACT. More studies are warranted to better understand the indication of systemic treatment escalation in this scenario.

PURPOSE: to assess the helicoid biopsy performance when carrying out breast biopsies. METHODS: thirty patients with breast cancer submitted to mastectomy were selected at random. Women with a tumor of petreous consistency, nonpalpable, submitted to previous surgical manipulation or containing fluid were excluded. The helicoid biopsy kit and a core biopsy device with a cannula and a 14-gauge-needle, respectively, were used to collect a fragment each from a healthy area and from the tumor of each surgical specimen, for a total of 120 fragments for histological study. Data were analyzed statistically by the parametric Student's t-test and by the Kappa concordance index at the 95% confidence level, using the SPSS software, version 13. RESULTS: the mean patient's age was 51.6 (±11.1) years old. The core biopsy showed 93.3% sensitivity, 100% specificity and 96.7% accuracy, and the helicoid biopsy showed 96.7% sensitivity, 100% specificity, and 98.3% accuracy. The comparison of tumor histology and biopsy fragments revealed a high degree of concordance in the diagnoses (Kappa equal to 0.9, with p<0.05). CONCLUSIONS: both methods provided a highly accurate histological diagnosis of the lesions. The results of the present study demonstrate that the helicoid biopsy is a reliable alternative for the preoperative diagnosis of breast lesions.

PURPOSE: to compare the epidemiologic and clinical characteristics, and the follow-up of breast cancer in women diagnosed under and over 40 years of age. METHODS: a retrospective study, case-control type, with analysis of information obtained from medical records of patients attended from January 1994 to June 2004. Cases of intraductal carcinoma and at stage IV were excluded. Three groups were formed: patients under 40 years old at the diagnosis (n=72); patients between 40 and 50 (n=68) and patients over 50 (n=75). Data about age at the moment of diagnosis, lesion largest diameter, clinical stage, type, histological grade, presence of hormonal receptors and state of the lymph nodes were collected and analyzed. The chi2 test was used for qualitative variables. For quantitative variables without normal distribution (such as number of axillary nodes with metastasis and follow-up duration), the Kruskal-Wallis' test was used. For delineating the curves of free-of-disease and global survival, the log-rank test was used. RESULTS: there was no difference among the groups in the stage distribution, concerning the tumoral differentiation grade or in the distribution of histological types, and in the estrogen receptor and c-erb-B2 expression. Difference was found in the RP expression, which was less frequent in the group of patients under 40, than in the group of patients over 50 (36.2% versus 58.4%) respectively. There was no difference among the groups in the mean tumoral diameter (5.1, 4.7 and 5 cm, respectively). There was also no difference among the groups, concerning the rate of axillary lymph node metastasis (63.9, 46.9 and 50%, respectively). The average follow-up was 54 months for all the groups. Disease recurrence occurred in 22.6% of patients under 40 years old, in 60% of patients between 40 and 50, and in 22.6% of patients over 50, with a significant difference among groups (p<0.0001). Death caused by the disease was higher among patients under 40 (46.9%) than among patients between 40 and 50 (26.9%) and over 50 (22.6%), p=0.0019. The logistic analysis showed that "age under 40" and the "presence of more than one metastatic axillary node" were independent death risk factors. CONCLUSIONS: age under 40 is an independent risk factor for breast cancer. The traditional prognostic indicators, such as stage, tumoral diameter, axillary involvement and presence of hormonal receptors are not associated with the disease evolution.

Purpose: to evaluate the advantages of the laparoscopic approach for conversion of abdominal hysterectomies in vaginal hysterectomies in patients with indication of concomitant adnexectomy, being considered the safety and the additional costs of the procedure. Patients and Methods: cases: 9 patients submitted to Laparoscopically Assisted Vaginal Hysterectomy (LAVH) associated with adnexectomy. Controls:18 patients submitted to Abdominal Hysterectomy (AH) associated with adnexectomy. Both groups were compared regarding preoperative characteristics and the results of the procedure. The patients submitted to LAVH and AH are similar concerning age, parity, cesarean deliveries, previous surgeries and body mass index. Results: the average surgery time was 163.9 minutes for patients submitted to LAVH and 142.8 minutes for patients submitted to AH. No patient in the LAVH group presented postoperative complications, while in the AH group 2 patients presented suture deiscence and there was 1 case of incisional hernia. The median of hospital stay was 1 day in the LAVH group and 2 days in the AH group, those of convalescence periods were 2 and 4 weeks, respectively. 55.6% of the patients in the LAVH group and 100% in the AH group needed analgesics in the postoperative period. Conclusions: LAVH was shown to be advantageous in relation to AH in terms of better recovery and lower incidence of complications in the postoperative period. The procedure is feasible and safe in a University Hospital, and without additional costs.

Purpose: to evaluate the correlation between clinical and surgical staging of patients with vulvar carcinoma, according to the "Federação Internacional de Ginecologia e Obstetrícia" (FIGO 95). Methods: the authors studied 66 consecutive cases of vulvar carcinoma from 1977 to 1997. All patients were clinically staged to verify size and localization of the lesion as well as inguinal lymph node involvement and invasion of other organs. Forty-four patients were submitted to surgical treatment and 34 could be staged according to FIGO 95. Results: among the 34 patients staged through surgery, 17 (50%) showed agreement between clinical and surgical staging. Thus, in 17 patients the staging was different and in these the surgical staging was higher than the clinical in 13 cases and lower in 4 cases. We found in the clinical staging I, 2 cases that were surgical stage II and 1 case that was surgical stage III. Conclusion: the surgical staging could detect lymph node metastasis in patients with clinically negative nodes, as well as exclude false-positive cases. The clinical staging was not accurate for patients with vulvar carcinoma.

Macroprolactinomas are benign prolactin-secreting pituitary tumors, causing amenorrhea, galactorrhea and gonadal dysfunction. Clinical treatment with dopamine agonists is the first-choice therapy. Surgery is indicated for the rare cases that are resistant to clinical treatment, when there is intolerance to the medication, or intratumoral hemorrhage is detected. We describe the case of a female patient with macroprolactinoma submitted to two surgical procedures and resistant to clinical treatment, with unusual evolution.

PURPOSE: to identify the risk factors associated with the occurrence of surgical site infection (SSI) in surgeries for the treatment of breast cancer. METHODS: the study was conducted on 140 women submitted to treatment of invasive breast cancer during the period from January 2001 to December 2002. SSI was defined as infection occurring up to 30 days after surgery and was related to the operation, according to the standard criteria adopted by the Centers for Disease Control and Prevention (CDC), USA. SSI were considered to be superficial when they involved only the skin and subcutaneous tissue and deep when they involved deep tissues at the site of incision, such as fascia and muscles. The risk factors related to patient were age, hormonal status, staging, body mass index (BMI) and hemoglobin, and the factors related to surgery were type of operation, time of hospitalization, duration of surgery, and formation of seroma and hematoma. Data concerning numerical nonparametric variables were analyzed by the Mann-Whitney test and quantitative variables were analyzed by the Fisher exact test. RESULTS: of the 140 patients studied, 29 (20.7%) presented SSI, which were superficial in 19 (13.6%) and deep in 10 (71%); 111 patients did not present SSI and represented the control group. The risk factors associated with the patient and the disease were locally advanced stage (odds ratio = 27; 95% CI: 1.1-6.5) and obesity, represented by a mean BMI of 32.2 kg/m² in the patients with SSI and a mean BMI of 27.2 kg/m² in the control group (p<0.0001). The factors related to treatment of the disease were the use of neoadjuvant chemotherapy (odds ratio = 2.7 (95% CI: 1.1-6.5), the duration of surgery, whose median value was 165 minutes for the patients who developed the infection and 137 minutes for the control group (p=0.02), and the number of days of use of the postoperative drain, whose median value was 6 days for the patients with SSI and 5 days for the control group (p=0.048). CONCLUSION: on the basis of the identification of risk factors such as advanced stage, neoadjuvant chemotherapy and obesity, preoperative care for these patients should be emphasized. The use of an accurate surgical technique may reduce the impact of other factors such as surgical time and time of use of the drain.
