Introduction Chemotherapy can cause sleep disorders, anxiety, depression, and decreased quality of life (QoL). This study aimed to compare sleep, QoL during chemotherapy in patients with breast cancer provide appropriate treatment at the time. Methods prospective included who received Pusan National University Yangsan Hospital. We used three self-reporting questionnaires regarding (QoS), QoL. was measured using Pittsburgh Sleep Quality Index, anxiety Beck Anxiety Inventory, depression...
Graft copolymer composed hyaluronic acid (HA) and poly(d,l-lactide-co-glycolide) (PLGA) (HAgLG) was synthesized for antitumor targeting via CD44 receptor of tumor cells. The carboxylic end PLGA conjugated with hexamethylenediamine (HMDA) to have amine group in the chain (PLGA-amine). PLGA-amine coupled HA. Self-assembled polymeric micelles HAgLG spherical morphologies their sizes were around 50–200 nm. Doxorubicin (DOX)-incorporated prepared by dialysis procedure. DOX released over 4 days...
<b><i>Purpose:</i></b> Quality of sleep (QoS), anxiety, depression, and quality life (QoL) are common issues among breast cancer patients. Prospective longitudinal studies QoS, QoL in patients lacking. The aim this study was to find out whether there is a proper treatment point associated with during early <b><i>Methods:</i></b> We used 4 self-report questionnaires about QoL. QoS measured using the Pittsburgh Sleep Index, anxiety Beck Anxiety...
To determine the quality of life (QoL) breast cancer patients who underwent mastectomy and immediate reconstruction with a latissimus dorsi myocutaneous flap (LD), oncological safety procedure. Between May 2001 March 2007, 2,566 had surgery at National Cancer Center, Korea. Of patients, 1,699 breast-conserving (BCS) 120 an LD. We retrospectively compared oncologic two techniques. also assessed QoL using EORTC QLQ BR-23 Zung's self-rating depression scale in 52 LD 104 age- stage-matched BCS,...
Block copolymers composed of poly(3-hydroxyoctanoate) (PHO) and methoxy poly(ethylene glycol) (PEG) were synthesized to prepare paclitaxel-incorporated nanoparticle for antitumor drug delivery. In a (1)H-NMR study, chemical structures PHO/PEG block confirmed their molecular weight (M.W.) was analyzed with gel permeation chromatography (GPC). Paclitaxel as model anticancer incorporated into the nanoparticles copolymer. They have spherical shapes particle sizes less than 100 nm. study in D2O,...
The bow wave generated by a steadily advancing ship is considered for family of fine ruled bows with rake and flare. This defined in terms four parameters: the draft D, entrance angles a' at top bottom waterlines, angle 8. corresponding similarly depends on draft-based Froude number F three a, a', An extensive parametric study, based thin-ship theory, performed to explore variations water height Z0 stem X = 0, location X0 (measured from stem) intersection bow-wave profile mean free-surface...
In immediate breast reconstruction using an extended latissimus dorsi musculocutaneous (eLDMC) flap, the volume of flap decreases, which causes a secondary deformity shape. Since little research has investigated this decrease in muscle volume, authors conducted objective study to characterize after eLDMC flap.Research was from October 2011 November 2016. The subjects included 23 patients who underwent mastectomy due cancer, received without any adjuvant chemotherapy or radiotherapy, and...
This study aimed to evaluate the volume reduction of latissimus dorsi muscle in patients who underwent immediate breast reconstruction using extended musculocutaneous (eLDMC) flap with implant after skin/nipple sparing mastectomy (SSM/NSM) and postoperative chemotherapy (POCTx).We retrospectively reviewed clinical records 19 this surgery POCTx, checked chest computer tomography (CT) at 7-10 days 6-14 months end chemotherapy, from May 2015 October 2016. The motor nerve was severed all...
Purpose: The BRCA1/2 gene is the most well-known and studied associated with hereditary breast cancer. genetic testing widely performed in high-risk patients of cancer Korea. This study aimed to investigate clinicopathological characteristics mutation-positive patients. Methods: clinical data 188 Korean who underwent mutation between March 2015 February 2020 at Pusan National University Yangsan Hospital were retrospectively reviewed. according expression BRCA1 BRCA2 mutations analyzed using...
543 Background: Robot-assisted breast conserving surgery (RABCS) have cosmetic benefit without any scar on the over conventional (CBCS). However, data feasibility and safety of RABCS are limited. The aim this study was to present results early experience RABCS. Methods: A multi-center retrospective review conducted identify women who underwent as part Korea Robot-Endoscopy & Minimal Access Breast Surgery Study Group (KoREa-BSG) between August 2019 October 2023. Information...
Background Implant-based immediate breast reconstruction surgery with nipple-sparing mastectomy has recently been favored by patients. However, in patients who do not wish to undergo balancing procedures, it is difficult select the appropriate implant size, making challenging achieve a symmetrical shape. Therefore, this study investigated differences asymmetry and other complications underwent two-stage procedure or direct-to-implant (DTI) determine whether can produce more favorable...
Breast reconstruction using an extended latissimus dorsi (eLD) flap can supplement more volume than various local flaps after partial mastectomy, and it is a valuable surgical method since the area not limited. However, when performing reconstruction, surgeon should consider (LD) reduction due to postoperative chemotherapy (POCTx) radiotherapy (PORTx). To evaluate effect of POCTx PORTx on LD reduction, effects each therapy-both separately jointly-need be demonstrated. The present study...
Background In performing extended latissimus dorsi (ELD) flap procedures, a skin paddle design on the bra line helps reduce visible scarring. This improves patient’s satisfaction with outcome. However, such leads to longer operation time and increased fatigue of surgeon due narrow operative field. this study, authors propose method that elongates axillary incision posteriorly by 1.5 cm from lateral border muscle. We examined whether could shorten compared incidence complications between...
Background Reduction mammoplasty or mastopexy is performed as an additional balancing procedure in patients with large ptotic breasts who undergo breast-conserving surgery (BCS). Radiation therapy on that have undergone may result changes the volume. This study presents a comparative analysis of received post-BCS procedures to determine whether volume were larger radiation than contralateral side. Methods Thirty-six participants selected among BCS using inverted-T scar technique between...
Background In recent years, breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has emerged as an important concern. At our institution, patients who received reconstruction using Allergan implants were informed individually about BIA-ALCL. The present study analyzed correlations between patients’ level of satisfaction with their shape and whether they chose to undergo reoperation (implant removal or replacement).Methods Breast was performed December 2014 April 2018. total,...
Background and Objectives: To determine the percentage of breast cancers detectable by fused diffusion-weighted imaging (DWI) using unenhanced magnetic resonance (MRI) abbreviated post-contrast-enhanced MRI. Materials Methods: Between October 2016 2017, 194 consecutive women (mean age, 54.2 years; age range, 28–82 years) with newly diagnosed unilateral cancer, who underwent preoperative 3.0 T MRI DWI, were evaluated. Both DWI independently reviewed two radiologists for detection index cancer...
