The Usefulness of Periareolar Zigzag Incision in Breast Conserving-Surgery in Breast Cancer Patients: Experience in a Single Institution

Purpose@#Various incision techniques have been used in breast-conserving surgery (BCS) to reduce scar formation, including the frequently used periareolar incision technique. However, its applicability in removing large-size tumors or those distant from the nipple has remained limited. We performed periareolar zigzag (P-Z) incision to address these problems in BCS and to improve cosmetic outcomes. @*Methods@#Patients who underwent P-Z incision in BCS between January 2016 and November 2017 were retrospectively analyzed in terms of clinicopathological features and surgical findings. Factors affecting the positive margin were analyzed. @*Results@#A total of 305 patients were reviewed. The patients presented with a median age of 51 years, mean tumor size 1.9 cm, and mean tumor distance of 3.3 cm from the nipple. Intraoperative frozen biopsy and final pathologic findings showed 43 (14.1%) and 7 (2.3%) tumor-positive margins. There were no major complications associated with the surgery, and no re-operations were required due to bleeding or other reasons. @*Conclusion@#The P-Z incision technique was used to achieve sufficient operative field during BCS, and large tumors or those distant from the nipple could be removed without any complications. This technique is considered an oncologically safe surgical technique resulting in good cosmetic outcomes.

Long-term Follow-up of Pure Ductal Carcinoma in situ after Breast-Conserving Surgery

PURPOSE@#Ductal carcinoma in situ (DCIS) is a high-risk disease for the development of invasive tumors. Although it is associated with excellent prognosis, many patients undergo extensive treatment with surgery, radiation, and endocrine therapy. This study evaluated the clinical and pathologic factors associated with invasive recurrence, particularly locoregional, distant disease after breast-conserving surgery (BCS).@*METHODS@#This study included 431 patients diagnosed with pure DCIS after BCS between January 2000 and December 2008. The clinicopathological characteristics, margin status, adjuvant therapy, and duration of endocrine therapy were evaluated in hormone receptor-positive DCIS patients.@*RESULTS@#The median duration of follow-up was 115 months. During this period, 37 cases (8.5%) of recurrence were observed (12 in situ and 23 invasive recurrence and 2 unknown cases). There was no distant metastasis as first event. Similarly, none of the initial in situ recurrence cases developed distant metastasis while eight (32%, 8/23) developed distant metastasis after invasive recurrence. Overall recurrence was associated with young age (≤40 years) (HR: 3.60, 95% confidence interval [CI]: 1.77–7.32) and hormone receptor negativity (HR: 3.33, 95% CI: 1.52–7.29). Invasive local recurrence was independently associated with young age (≤40 years) (HR: 3.86, 95% CI: 1.50–9.96), high nuclear grade (HR: 4.46, 95% CI: 1.62–12.27) and omission of adjuvant radiotherapy (HR: 6.45, 95% CI: 1.82–22.82). Notably, duration of endocrine treatment among the hormone receptor positive patient group, was numerically shorter for recurred patients, though not statistically significant.@*CONCLUSION@#Young age, high nuclear grade and absence of adjuvant radiotherapy were independently associated with an increased risk of invasive recurrence. Moreover, invasive locoregional recurrence as a first event was associated with worse outcomes, yet in situ recurrence didn't affect overall survival. Further studies with larger sample sizes are warranted to confirm the prognostic indicators of recurrence and the optimal strategy for adjuvant therapy in this setting.

The Importance of Education regarding the Effects of Anticancer Treatment on Fertility and Ovarian Function in the Female Patients with Breast Cancer

OBJECTIVES: Female breast cancer patients generally have limited knowledge regarding issues related to preservation of ovarian function and fertility. The present study aimed to explore the change in the understanding of these issues when female breast cancer patients are educated and counseled about ovarian function and fertility after anticancer treatment.METHODS: One hundred nine young female breast cancer patients completed a questionnaire, which revealed their thoughts and opinions before and after receiving the education about ovarian function and fertility. Their responses were analyzed to determine the impact of the education on their perception and understanding of the aforementioned issues.RESULTS: The objective survey had four main themes: planning and desire for children, degree of baseline understanding of the effects of anticancer therapy on fertility and ovarian function, resultant change in cognition after education about cancer treatment and its relationship with fertility, and need for education regarding the types of therapies received and their effects on subsequent ovarian function and fertility before treatment.CONCLUSIONS: The preservation of ovarian function and fertility is an important factor that must be included in the discussion prior to initiation of anticancer therapy. Although the study results do not have high educational effectiveness or a high satisfaction with education, there is a need for information and education regarding the impact of anticancer treatment on preservation of ovarian function and fertility.

No Association of Positive Superficial and/or Deep Margins with Local Recurrence in Invasive Breast Cancer Treated with Breast-Conserving Surgery / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: We evaluated the effect of positive superficial and/or deep margin status on local recurrence (LR) in invasive breast cancer treated with breast-conserving surgery (BCS) followed by radiotherapy. MATERIALS AND METHODS: In total, 3,403 stage 1 and 2 invasive breast cancer patients treated with BCS followed by radiotherapy from January 2000 to December 2008 were included in this study. These patients were divided into three groups according to margin status: clear resection margin status for all sections (group 1, n=3,195); positive margin status in superficial and/or deep sections (group 2, n=121); and positive peripheral parenchymal margin regardless of superficial and/or deep margin involvement (group 3, n=87). The LR-free survival between these three groups was compared and the prognostic role of margin status was analyzed. RESULTS: Across all groups, age, tumor size, nodal status, and human epidermal growth factor receptor 2 status did not significantly differ. High grade, positive extensive intraductal component, hormone receptor positivity, hormone therapy received, and chemotherapy not received were more prevalent in groups 2 and 3 than in group 1. Five-year LR rates in groups 1, 2, and 3 were 1.9%, 1.7%, and 7.7%, respectively. Multivariate analysis revealed that group 3 was a significant predictor for LR (hazard ratio [HR], 4.78; p < 0.001), but that positive superficial and/or deep margin was not (HR, 0.66; p=0.57). CONCLUSION: Superficial and/or deep margin involvement following BCS is not an important predictor for LR.

The Optimal Concentration of Alfentanil in Combination with 0.15% Ropivacaine for Postoperative Patient-Controlled Epidural Analgesia / 대한마취과학회지

BACKGROUND: The aim of this randomized double-blinded study was to determine the optimal concentration of alfentanil with 0.15% ropivacaine for postoperative patient-controlled epidural analgesia. METHODS: Forty five patients undergoing major abdominal surgery under general anesthesia were assigned to groups receiving patient-controlled thoracic epidural analgesia with 0.15% ropivacaine + 45 microgram/ml alfentanil (Group I), 75microgram/ml alfentanil (Group II), 150 microgram/ml alfentanil (Group III). The incidence of side effects and additional analgesic use, VAS (visual analog pain scale) on resting and coughing, and patient's satisfaction were checked for 24 hours after a loading dose injection. RESULTS: The VAS on coughing and resting 1 hour after the loading dose injection were significantly lower in Groups II and III than in Group I. The patients in group II were more satisfied with the result than those in Group I. CONCLUSIONS: A combination of 0.15% ropivacaine and 75microgram/ml alfentanil for thoracic epidural analgesia after major abdominal surgery provides the best analgesia with minimal side effects and a higher level of patient's satisfaction.

Change of Tumor Necrosis Factor-alpha Concentration after Pediatric Cardiopulmonary Bypass and Its Relationship with Postoperative Course / 대한마취과학회지

BACKGROUND: Systemic inflammatory response after open heart surgery has an adverse effect on the postoperative course of patient, and results from the release of cytokines by leukocytes activated by cardiopulmonary bypass (CPB). TNF-alpha has an important role in inflammatory response-it has clinical effects such as fever, tachycardia, and hypotension, and also induces other cytokines. However studies about the change of blood concentration of TNF-alpha after CPB show differing results, and so have been up to now inconclusive, we have therefore endeavored to investigate the change of TNF-alpha level after CPB and its relationship with the postoperative course of patients. METHODS: We studied 20 children undergoing open heart surgery. Serum TNF-alpha was detected after induction (control), 5 minutes after onset of CPB (T1), 5 minutes after release of aortic cross clamp (T2), and 30 minutes after CPB (T3) by enzyme-linked immunosorbent assay. We compared the concentration of TNF-alpha and the duration that patients stayed in intensive care unit (ICU) and were supported by mechanical ventilator in group I (CPB time 60 minutes, n = 10). RESULTS: TNF-alpha levels of S2 and S3 were significantly lower than those of S1 and S4 (P = 0.001), but no difference was detected between group I and II. No statistical relationship was found linking TNF-alpha levels with the duration in ICU, or time supported by mechanical ventilator. Three children with postoperative complications showed higher level of TNF-alpha than others (P = 0.002). CONCLUSIONS: We concluded that TNF-alpha levels decreased during CPB, did not increased after CPB, and had no relationship to such postoperative courses as postoperative ICU time and intubation time, but there was a correlation with postoperative complications.

The Effects of Enflurane and Isoflurane on Hepatic Functins in Children with Hepatic Dysfunction / 대한마취과학회지

The effects of enflurane and isoflurane on the postoperative hepatic function were compared in 39 pediatric patients with preoperative mild abnormal hepatic functions. The pediatric patients were divided randomly into two groups of enflurane(=20) and isoflurane(n=19). Anesthesia was maintained 1 MAC of each anesthetic combined with 50% oxygen and 50% nitrous oxide. Serum glutamic-oxaloacetic transaminase(SGOT), serum glutamate pyruvate transaminase (SGPT), total bilirubin, alkaine phosphatase, eosinophil count, body temperature were measured preoperatively, and on postoperative 1 and 3 day. Authors compared above parameters within the group and between two groups. There were no statistically significant differencies in hepatic function, eosinophil count, and body temperature within the group and between two groups. Thus, this study shows that enflurane and isoflurane would not affect hepatic function in pediatric patients with mild hepatic dysfunction.
