RESUMEN
BACKGROUND: The targeted axillary dissection (TAD) procedure is used in clinically positive lymph node (cN+) breast cancer to assess whether pathological complete response (pCR) is achieved after neoadjuvant systemic therapy (NST) to decide on de-escalation of axillary lymph node dissection (ALND). In this study, we review the implementation of the TAD procedure in a large regional breast cancer center. METHODS: All TAD procedures between 2016 and 2022 were reviewed. The TAD procedure consists of marking pre-NST the largest suspected metastatic lymph node(s) using a radioactive I-125 seed. During surgery, the marked node was excised together with a sentinel node procedure. Axillary therapy (ALND, axillary radiotherapy, or nothing) recommendations were based on the amount of suspected positive axillary lymph nodes (ALNs < 4 or ≥ 4) pre-NST and if pCR was achieved after NST. RESULTS: A total of 312 TAD procedures were successfully performed in 309 patients. In 134 (43%) cases, pCR of the TAD lymph nodes were achieved. Per treatment protocol, 43 cases (14%) did not receive any axillary treatment, 218 cases (70%) received adjuvant axillary radiotherapy, and 51 cases (16%) underwent an ALND. During a median follow-up of 2.8 years, 46 patients (14%) developed recurrence, of which 11 patients (3.5%) had axillary recurrence. CONCLUSIONS: Introduction of the TAD procedure has resulted in a reduction of 84% of previously indicated ALNDs. Moreover, 18% of cases did not receive adjuvant axillary radiotherapy. These data show that implementation of de-escalation axillary treatment with the TAD procedure appeared to be successful.

AIM: We investigated the pathologic complete response rates (pCR) and survival outcomes of early breast cancer patients who underwent neoadjuvant chemotherapy (NAC) over 14 years at a French comprehensive cancer center and reported pCR and survival outcomes by tumor subtypes and size. METHODS: From January 2005 to December 2018, 1150 patients receiving NAC were identified. Correlations between cT stage, breast tumor response, axillary lymph node response, pCR, surgery, and outcomes were assessed. pCR was defined as (ypT0/ypTis) and (ypN0/pN0sn). RESULTS: A pCR was reached in 31.7% (365/1150) of patients and was strongly associated with tumor subtypes, but not with tumor size (pretreatment cT category). Luminal-B Her2-negative and triple-negative (TN) subtypes, cN1 status, older age, and no-pCR had an independent negative prognostic value. Overall survival (OS), relapse-free survival (RFS), and metastasis-free survival (MFS) were not significantly different for cT0-1 compared to cT2 stages. In Cox-model adjusted on in-breast pCR and pN status, ypN1 had a strong negative impact (OS, RFS, and MFS: HR = 3.153, 4.677, and 6.133, respectively), higher than no in-breast pCR (HR = 2.369, 2.252, and 2.323). A negative impact of no pCR on OS was observed for cN0 patients and TN tumors (HR = 4.972) or HER2-positive tumors (HR = 11.706), as well as in Luminal-B Her2-negative tumors on MFS (HR = 2.223) and for Luminal-A on RFS (HR = 4.465) and MFS (HR = 4.185). CONCLUSION: Achievement of pCR, but not tumor size (pretreatment cT category), has an independent prognostic impact on survival. These results suggest potential NAC benefits in patients with small tumors (<2 cm), even in absence of clinically suspicious lymph nodes. Residual lymph node disease after NAC is the most powerful adverse prognostic factor.

INTRODUCTION: Sentinel lymph node biopsy for breast cancer is a method to localize and excise the first draining lymph node from an invasive cancer of the breast. The histopathologic evaluation of the sentinel lymph node is used for predicting recurrence and survival and thus, guiding oncologists for treatment-decision making to administer adjuvant therapies. The ability to identify the sentinel node depends on methods to map lymphatic drainage from the breast to the sentinel node and accurately discriminate that node from other non-sentinel lymph nodes of the axilla. AREAS COVERED: This review covers the clinical demand for technologies to assist the surgeon in intraoperative lymphatic mapping to specifically identify the sentinel lymph node in patients with breast cancer. Performance characteristics are reviewed for superparamagnetic iron oxide tracers used in lymphatic mapping compared to other current available technologies for lymphatic mapping. EXPERT OPINION: The Magtrace (superparamagnetic iron oxide tracer) Sentimag (handheld magnetic probe) system is an FDA-approved technology for intraoperative lymphatic mapping to facilitate sentinel lymph node biopsy in breast cancer with technologic performance characteristics that are equivalent to 99Technetium-sulfur colloid. Barriers to broader utilization primarily center around the need for nonmetallic devices to be used for the conduct of surgery, which would interfere with the paramagnetic method for tracer localization.

BACKGROUND: In 2016, the SSO and ABIM released a Choosing Wisely® guideline stating SLNB can be safely omitted in women ≥70 with HR â+ âHER-invasive breast cancer. No study evaluating concordance of care with this guideline has been performed within a comprehensive cancer center. METHODS: From 2005 to 2020, there were 382 patients with cT1-2N0 invasive carcinoma ER+/PR+ and HER2-identified as having undergone SLNB. These patients were then separated into two groups; those in the pre-guideline concordance cohort (2005-2015) and those in the post-guideline concordance (2016-2020) cohort. Axillary management concordance was trended over time. RESULTS: 382 patients from 2005 to 2020 with HR â+ âHER- IBC were identified. No difference was seen in SLNB pre-versus post-guidelines (p â= â0.35). Increased concordance was noted as age increased (p â= â0.0068) and adjuvant radiation therapy exclusion (p â< â0.0001) post-guideline release. Concordance improved over the years post-guideline release (R2 â= â0.45). CONCLUSIONS: Surgical guideline adoption occurs over time but may also be affected by outside decisions and factors. Further study into patterns of guideline adoption may facilitate improving adherence to guidelines.

Sentinel lymph node (SLN) status is closely related to axillary lymph node metastasis in breast cancer. However, SLN biopsy has certain limitations due to invasiveness and diagnostic efficiency. This study aimed to develop a model to predict the risk of axillary SLN metastasis in early-stage breast cancer based on mammography, a noninvasive, cost-effective, and potential complementary way. Herein, 649 patients with early-stage breast cancer (cT1-T2) who received SLN biopsy were assigned to the training cohort (n = 487) and the validation cohort (n = 162). A prediction model based on specific characteristics of tumor mass in mammography was developed and validated with R software. The performance of model was evaluated by receiver operating characteristic curve, calibration plot, and decision curve analysis. Tumor margins, spicular structures, calcification, and tumor size were independent predictors of SLN metastasis (all P < .05). A nomogram showed a satisfactory performance with an AUC of 0.829 (95% CI = 0.792-0.865) in the training cohort and an AUC of 0.825 (95% CI = 0.763-0.888) in validation cohort. The consistency between model-predicted results and actual observations showed great Hosmer-Lemeshow goodness-of-fit (P = .104). Patients could benefit from clinical decisions guided by the present model within the threshold probabilities of 6% to 84%. The prediction model for axillary SLN metastasis showed satisfactory discrimination, calibration abilities, and wide clinical practicability. These findings suggest that our prediction model based on mammography characteristics is a reliable tool for predicting SLN metastasis in patients with early-stage breast cancer.

BACKGROUND: Lasers of different wavelengths have been developed for use in permanent hair reduction. An increase in the manufacturing of home-use laser hair removal devices allows for these treatments to be performed in the comfort of your own home at an affordable cost. OBJECTIVE: To evaluate the effectiveness of permanent hair reduction using a Diode laser in comparison to the Silk'n™ Flash and Go Lux (475-1200 nm) home-use laser. METHODS: Fifteen females received six axillae laser hair removal treatments at two to four-week intervals using either a professional laser or home-use laser device. Photographs and hair counts were taken before each treatment and at a three week follow up. A T-test was used to evaluate statistical significance, and regression analysis to determine a difference in the effects. Pain scores and side effects were recorded by a visual analogue scale in a satisfaction questionnaire. RESULTS: The professional laser showed an overall hair reduction of 85% on the right axilla and 88% on the left axilla. The home-use laser showed an overall reduction of 52% on the right axilla and 46,3% on the left axilla. Mild side effects were experienced for both laser devices. There were no serious adverse effects reported, safety features are effective to a certain extent. CONCLUSION: The Flash & Go Lux home-use laser can effectively reduce hair at a slower rate than the Diode laser. The home-use laser device offers protection against accidental exposure to light and use on darker skin types. Risks of retinal damage due to long-term exposure to home-use laser light are still cause for concern.

BACKGROUND AND OBJECTIVES: This study describes the intramuscular nerve branching of the deltoid muscle in relation to shoulder surface anatomy, with the aim of providing essential information regarding the most appropriate sites for botulinum neurotoxin injection during shoulder line contouring. METHODS: The modified Sihler's method was used to stain the deltoid muscles (16 specimens). The intramuscular arborization areas of the specimens were demarcated using the marginal line of the muscle origin and the line connecting the anterior and posterior upper edges of the axillary region. RESULTS: The intramuscular neural distribution of the deltoid muscle had the greatest arborization patterns in the area between the horizontal 1/3 and 2/3 lines of the anterior and posterior deltoid bellies, and 2/3 to axillary line in middle deltoid bellies. The greatest part of the posterior circumflex artery and axillary nerve ran below the areas with the highest aborizations. CONCLUSION: We propose that botulinum neurotoxin injections should be administered in the area between the 1/3 and 2/3 lines of the anterior and posterior deltoid bellies, and 2/3 to axillary line on middle deltoid bellies. Accordingly, clinicians will ensure minimal dose injections and fewer adverse effects of the botulinum neurotoxin injection. Deltoid intramuscular injections, such as vaccines and trigger point injections, should ideally be adapted according to our results.

BACKGROUND: Laser has been long accepted as a solution for excess or unwanted hair growth yet traditional lasers are not always ideal for safe and effective outcome for all skin types and hair characteristics. A diode laser module combining three wavelengths (755, 810, and 1064 nm) in a single pulse was developed to provide a fast and long-term solution for subjects with various profiles. AIMS: To evaluate the safety and efficacy of a Triple wavelength diode laser module for hair removal treatment in all skin types (Fitzpatrick I-VI). SUBJECTS AND METHODS: This was a prospective, dual centered, single-arm study. Subjects were treated with a novel diode laser module. Thirty-six subjects were enrolled, sixteen with Fitzpatrick skin types I-IV (46%) and twenty with Fitzpatrick skin types V-VI (54%). Treatment areas were axilla and bikini lines. Subjects underwent 4 treatment sessions at 6 weeks ± 5 days intervals and attended a follow-up visit 3 months after the last treatment session. 2D digital photographs were taken at baseline and at the follow-up visit, and a hair count was conducted by three blinded evaluators. RESULTS: A significant reduction in hair count between baseline and the 3-month follow-up visit was observed in both axilla and bikini lines for all skin types. The mean hair reduction was 41.5 ± 19.4% and 48.1 ± 20.9% in the axilla and bikini line, respectively. A significant hair reduction was also observed within skin type groups; mean hair reduction 45.5 ± 16.9% and 40.3 ± 17.2% in skin types I-IV and V-VI, respectively, indicating similar efficacy for both light and dark skin types. No serious adverse events were reported. CONCLUSIONS: This study demonstrates that the Soprano Titanium laser platform is safe and effective for hair removal treatment in all skin types.

The aim of the study was to explore the application value of manual lymphatic drainage combined with vacuum sealing drainage in axillary web syndrome (AWS) after breast cancer surgery. From 1 April 2020 to 1 June 2020, a total of 102 patients with AWS after axillary lymph node biopsy or axillary lymph node dissection in our hospital were included in this prospective study. According to the random number table method, all patients were divided into the study group (n = 51) and the control group (n = 51). The study group received the treatment of manual lymphatic drainage combined with vacuum sealing drainage, and the control group received health education and the treatment of functional training. The efficacy observation indicators included duration time to the disappearance of relevant clinical symptoms, degree of pain, angle of abduction of the affected limb, degree of upper limb disability function and quality of life. The duration time to the disappearance of cord-like nodules and tightness in the study group was both significantly shorter than that in the control group (both P < .05). In the time point of 1 and 3 months after the intervention, compared with that in the control group, the study group had a significantly lighter degree of pain, a better degree of upper limb disability function and higher quality of life (all P < .05). Manual lymphatic drainage combined with vacuum sealing drainage can shorten the disappearance time of relevant clinical symptoms, relieve the degree of pain, improve the upper limb disability function and improve the quality of life in patients with AWS.

PURPOSE: Axillary lymph node dissection and radiotherapy have been associated with pain, physical symptoms, and decreased functional abilities in the upper extremity. This study aimed to evaluate the potential effects of the proprioceptive neuromuscular facilitation (PNF) technique on muscle strength, pain and functionality in this patient group in comparison with progressive resistance training (PRT). METHODS: The study was conducted with a randomized clinical trial design. Sixty-six women were included in the study and randomly divided into three groups: the PNF group (n = 22), the PRT group (n = 22), and the control group (n = 22). The participants were evaluated at the baseline and after eight weeks of treatment. Outcome measures were determined as pain (the Visual Analog Scale), upper extremity strength (isokinetic dynamometer), functionality (the Disabilities of the Arm, Shoulder and Hand questionnaire), and perception of change (the Global Rating of Change Scale). TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT05288036. RESULTS: The results showed statistically significant changes in both treatment groups in terms of shoulder flexors/extensors, abductor/adductors, internal/external rotators strength/power/endurance measurement, pain, and functionality (p < 0.05). Concerning functionality and perception of change, the PNF group had a statistically significantly higher improvement compared to the remaining two groups (p < 0.05). CONCLUSION: PNF is an effective technique in increasing upper extremity muscle strength, reducing pain during rest and activity, and improving functionality in patients receiving breast cancer treatment.

BACKGROUND: The need for axillary dissection (AD) is declining, but it is still essential for many patients with nodal involvement who risk developing breast-cancer-related lymphedema (BCRL) with lifelong consequences. Previous nonrandomized studies found axillary reverse mapping and selective axillary dissection (ARM-SAD) a safe and feasible way to preserve the arm's lymphatic drainage. METHODS: The present two-arm prospective randomized clinical trial was held at a single comprehensive cancer center to ascertain whether ARM-SAD can reduce the risk of BCRL, compared with standard AD, in patients with node-positive breast cancer. Whatever the type of breast surgery or adjuvant treatments planned, 130 patients with nodal involvement met our inclusion criteria: 65 were randomized for AD and 65 for ARM-SAD. Twelve months after surgery, a physiatrist assessed patients for BCRL and calculated the excess volume of the operated arm. Lymphoscintigraphy was used to assess drainage impairment. Self-reports of any impairment were also recorded. RESULTS: The difference in the incidence of BCRL between the two groups was 21% (95% CI, 3-37; p = .03). A significantly lower rate of BCRL after ARM-SAD was confirmed by a multimodal analysis that included the physiatrist's findings, excess arm volume, and lymphoscintigraphic findings, but this was not matched by a significant difference in patients' self-reports. CONCLUSIONS: Our findings encourage a change of surgical approach when AD is still warranted. ARM-SAD may be an alternative to standard AD to reduce the treatment-related morbidity.

INTRODUCTION: Breast cancer is the most common malignant tumour in women, with more than 2 million new cases annually worldwide. One of the most frequent and well-known surgical and post-actinic sequelae is post-mastectomy lymphoedema. The axillary web syndrome is another sequela that limits the functionality of the patient and delays the protocol time of administering cancer treatments; and in many cases, this sequela is misdiagnosed. This surgical sequela usually disappears spontaneously after the third month of appearance, but this implies a long period of discomfort and limitations for the patient, at the same time, it may delay the application of radiotherapy within the indicated protocol deadline (due to a need for body posture). METHODS AND ANALYSIS: With the present quasi-experimental study, we intend to show the application of physiotherapy and stretching from the beginning of the appearance of the axillary cord, in a controlled and scheduled way by the physiotherapist. It is possible to reduce the time in which the lymphatic thrombus is present and, therefore, recover functionality and mobility, reduce pain and be able to apply treatments within the established deadline. We intend to apply this therapy into the intervention group and compare thrombus evolution time with the control group. ETHICS AND DISSEMINATION: This trial has the approval of the Andalucía Ethics Committee (PEIBA code 1909-N1-21, reg. number 171.21). TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT05115799).

INTRODUCTION: Idiopathic hyperhidrosis is a dysfunctional disorder involving eccrine sweat glands, and its impact on patients' daily quality of life is well known. Unlike some years ago, when only poor effective and safe therapeutic alternatives were available, nowadays, several emerging pharmacological active substances have gained significant space as treatment options. AREAS COVERED: The authors report on, in this narrative review, the emerging data from the literature focusing on the pharmacological treatments to draw up a drug treatment flow chart for patients with idiopathic hyperhidrosis, taking into consideration specific differences among axillary, palmoplantar, and craniofacial hyperhidrosis. EXPERT OPINION: Idiopathic hyperhidrosis, regardless of the site of involvement, remains a functional disorder that places a significant burden on patients. After balancing efficacy against adverse events, systemic therapy, although off-label for all forms of hyperhidrosis, can be an added therapeutic option for patients with insufficient response to topical treatment. Until the pathophysiological mechanisms underlying hyperhidrosis are clear and the etiological therapeutic approach becomes realistic, the greatest challenge in the therapeutic management of hyperhidrotic patients seems to be the search for the most convenient combination between different therapeutic modalities (topical and systemic agents, and botulinum toxins) to achieve long-term control of the disease symptoms.

BACKGROUND: The changes in the pattern of lymphatic drainage of the superficial abdominal wall after abdominoplasty are still unknown. These changes may increase the risk of numerous complications, including seroma formation. Depending on the alterations, the manual lymphatic drainage technique should be modified in postoperative patients. The aim of this study was to map the pattern of lymphatic drainage of the superficial infraumbilical abdominal wall after abdominoplasty. METHODS: Twenty women with indications for abdominoplasty were selected in the Plastic Surgery Division of the Federal University of São Paulo. Intradermal lymphoscintigraphy with dextran 500-99m-technetium was performed in 20 female patients in the preoperative phase and 1 and 6 months after abdominoplasty to evaluate superficial lymphatic drainage of the abdominal wall. RESULTS: Before surgery, all patients presented with abdominal lymphatic drainage toward the inguinal lymph nodes. One and 6 months after abdominoplasty, only 15 percent exhibited the same drainage pathway. Drainage toward the axillary lymph node chain occurred in 65 percent of the patients, 10 percent displayed a drainage pathway toward both the axillary and inguinal lymph nodes, and lymphatic drainage was indeterminate in 10 percent of the cases. CONCLUSIONS: A significant change in lymphatic drainage pathway occurred in the infraumbilical region after abdominoplasty. The axillary drainage path was predominant after the operation, in contrast to the inguinal path observed in the preoperative period. However, 35 percent of cases exhibited alternative drainage. No significant changes were documented between 1 and 6 months postoperatively. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

OBJECTIVE: This study aimed to determine the effectiveness of a physical therapist-designed program tailored to axillary web syndrome (AWS) in women after breast cancer surgery. METHODS: A prospective, single-center, assessor-blinded, randomized controlled trial was conducted at the Physiotherapy in Women's Health Research Unit of the Alcalá University (Madrid, Spain). Ninety-six women with AWS were assigned to the physical therapy group (manual lymph drainage [MLD] using resorption strokes and arm exercises as if performing median nerve neurodynamic glide exercises with no neural loading; n = 48) or the control group (standard arm exercises; n = 48), with both groups receiving treatment 3 times a week for 3 weeks. Both interventions included an educational component. RESULTS: Compared with the control group, the physical therapy group showed significant and clinically relevant improvements in the primary outcome (self-reported pain intensity) at the primary and 3-month follow-ups. Significant and clinically relevant differences between groups were also found in the secondary outcomes (shoulder active range of motion, shoulder disability, and physical and functional aspects of health-related quality of life) at the primary follow-up and in the secondary outcomes as well as the trial outcome index at the 3-month follow-up. No significant differences were found at the 6-month follow-up in either primary or secondary outcomes. CONCLUSION: The physical therapy program tailored to AWS was found to be effective for AWS symptoms in women after breast cancer surgery, both immediately after the program and after 3 months. IMPACT: To our knowledge, this is the first appropriately designed study to demonstrate the effectiveness of MLD with progressive arm exercises for AWS. Clinicians and health service providers should consider how to provide survivors of breast cancer with AWS the opportunity to participate in physical therapy programs, including MLD with progressive arm exercises. LAY SUMMARY: For axillary web syndrome following breast cancer surgery, a physical therapist can design a treatment program including manual lymph drainage and progressive arm exercises, which has been shown to result in reduced pain and improved motion compared with standard arm exercises.

BACKGROUND: Prior studies examining sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NAC) for cN1 patients have demonstrated that 20% of biopsied, clipped lymph nodes (cLNs) are nonsentinel lymph nodes (non-SLNs). Our goal was to determine how often the cLN was a non-SLN among both cN0 and cN1 patients and how often cLN pathology impacted management. METHODS: Overall, 238 patients treated with NAC and surgery January 2019 to June 2020 were prospectively examined. Patients underwent routine axillary ultrasound, biopsy of suspicious nodes, and clip placement. Radioactive iodine-125 seed localization of the cLN was performed in cN1 patients only. Isolated tumor cells (ITCs) were considered node positive (ypN+) for both cN0 and cN1 cohorts. Chart review was performed to determine if cLNs were non-SLN and their ypN status. RESULTS: Of 118 cN0 patients, 115 of 118 (97%) underwent successful SLNB, 33 of whom had a cLN present; 21 of 33 (64%) cLNs were non-SLNs. Overall, 9 of 118 (8%) were ypN+; no cLN was ypN+ without additional +SLNs. Of 120 cN1 patients, 104 of 120 (87%) converted to cN0, 98 of 104 (94%) of which had attempted SLNB, and 95 of 98 (97%) successfully mapped. The cLN was a non-SLN in 18 of 95 (19%). Overall, 58 of 104 (56%) cN1 patients were ypN+. One patient had a positive cLN in the absence of +SLNs. This patient underwent axillary lymph node dissection (ALND); adjuvant treatment recommendations were unchanged. CONCLUSIONS: The cLN was a non-SLN in 19% of cN1 patients. cLN pathology did not impact adjuvant therapy recommendations, calling into question the utility of routinely clipping biopsied lymph nodes.

Axillary staging is 1 of the major issues of current breast cancer management after neoadjuvant systemic therapy (NST). Sentinel lymph node biopsy (SLNB) is an option for clinically node negative patients. Axillary reverse mapping (ARM) was introduced to identify and preserve the lymphatic drainage from the arm. The aim of the presented study is to employ triple mapping (radiocolloid, blue dye and indocyanine green [ICG]) to assess the crossover rate and metastatic involvement of ARM nodes after NST. Clinically node positive patients before NST who were converted to N0 and scheduled for targeted axillary dissection were included. sentinel lymph node (SLN) mapping was performed via dual agent mapping. ICG was used for ARM procedure. Blue, hot and fluorescent nodes and lymphatics were visualized in the axilla using infrared camera system and dual opto-nuclear probe (Euoroprobe3). Fifty-two patients underwent targeted axillary dissection and ARM procedures 12 out of whom had axillary node dissection. 45 of the 52 patients had at least 1 hot or blue SLN identified intraoperatively. Of these, 61.5% cases had hot SLNs, 42.3% had hot and blue, 15.4% had hot/blue/fluorescent, 7.7% had blue/fluorescent, 6 11.5% had hot/fluorescent and 7 13.5% had only clipped nodes. The overall identification rate of ARM-nodes by means of ICG technique was 86.5%. Overall crossover of ARM nodes with SLNs was determined in 36.5%. The ICG intensity was found to be higher in both hot and blue SLNS (8 out of 18 ICG positive cases, 44.4%). In 3 of 52 patients (5.7%) metastatic SLNs were hot or blue but fluorescent which predicts metastatic involvement of the ARM-nodes. More than 1-third of the patients revealed a crossover between arm and breast draining nodes. The higher observed rate of overlap might partially explain why more patients develop clinically significant lymphedema after NST even after sentinel lymph node biopsy alone. The triple mapping provides valuable data regarding the competency of lymphatic drainage and would have the potential to serve selecting patients for lymphovenous by-pass procedures at the index procedure. NST reduces the metastatic involvement of the ARM nodes. However, conservative axillary staging with sparing ARM nodes after NST necessitates further studies with larger sample size and longer follow-up.

BACKGROUND: The oil of the grass Cyperus rotundus (purple nutsedge) is an effective and safe treatment option for a variety of conditions. It has anti-inflammatory and antipigmenting properties. There have been no clinical trials comparing topical C. rotundus oil with skin-lightening treatments for axillary hyperpigmentation. AIM: To assess the efficacy of C. rotundus essential oil (CREO) in treating axillary hyperpigmentation, and compare with another active treatment hydroquinone (HQ) and a placebo (cold cream) in this study. METHODS: The study included 153 participants, who were assigned to one of three study groups: CREO, HQ group or placebo group. A tri-stimulus colorimeter was used to assess pigmentation and erythema. Two independent experts completed the Physician Global Assessment, and the patients completed a self-assessment questionnaire. RESULTS: CREO had significantly (P < 0.001) better depigmenting effects than HQ. CREO and HQ did not differ significantly in terms of depigmentation effects (P > 0.05); however, there were statistically significant differences in anti-inflammatory effects and decrease in hair growth (P < 0.05) in favour of CREO. CONCLUSIONS: CREO is a cost-effective and safe treatment for axillary hyperpigmentation.

AIMS: To identify the risk factors for lymphoedema following axillary lymph node dissection (ALND) in a European sample and to propose a lymphoedema prediction model for this population. DESIGN: Predictive retrospective cohort study comparing women who developed lymphoedema in 2 years of undergoing ALND with those who did not developed lymphoedema. METHODS: We reviewed the clinical records of 504 women who, between January 2008 and May 2018, underwent surgery for breast cancer that involved ALND. Logistic regression was used to identify significant risk factors for lymphoedema. The prediction accuracy of the model was assessed by calculating the area under the receiver operating characteristic curve. RESULTS: Of the 504 women whose records were analysed, 156 developed lymphoedema. Significant predictors identified in the regression model were level of lymph node dissection, lymph node status, post-operative complications, body mass index (BMI) and number of lymph nodes extracted. The prediction model showed good sensitivity (80%) in the study population. CONCLUSIONS: The factor contributing most to the risk of lymphoedema was the level of lymph node dissection, and the only patient-related factor in the prediction model was BMI. The model offers good predictive capacity in this population and it is a simple tool that breast care units could use to assess the risk of lymphoedema following ALND. Nurses with specialist knowledge of lymphoedema have a key role to play in ensuring that women receive holistic and individualized care. IMPACT: What problem did the study address? Secondary lymphoedema is one of the main complications in the treatment of breast cancer. What were the main findings? The prediction model included five factors associated with the risk of lymphoedema following ALND. The strongest predictor was the level of lymph node dissection, and the only patient-related factor was BMI. Where and on whom will the research have an impact? The prediction model offers breast care units a tool for assessing the risk of lymphoedema in women undergoing surgery involving ALND. The results highlight the importance of weight reduction as a preventive measure and support a more conservative surgical approach.

BACKGROUND: The latest National Comprehensive Cancer Network Breast Cancer Guidelines still discourage repeat sentinel node biopsy (SNB) after mastectomy, and the largest multicentric study available reports only 35 cases in the absence of previous axillary dissection (AD). METHODS: From January 2003 to November 2018, 89 patients of the European Institute of Oncology with local recurrence of breast cancer after mastectomy, free of distant metastases, with a clinically negative axilla and a negative axillary ultrasound, in absence of AD, underwent lymphatic mapping before wide local excision. RESULTS: During surgery, SNB was successful for 99% of the patients, with 14% being metastatic. Additional metastatic nodes removed by AD after a positive sentinel node occurred in 82% of cases. After a medium follow-up period of 3.7 years, the overall survival rate was 96.7%, and the disease-free survival rate was 84.4%. No axillary relapse after AD was recorded. One patient who refused human epidermal growth factor receptor 2 (HER2)-targeted treatment experienced ipsilateral axillary recurrence after a negative repeat SNB. The first axillary level was never directly irradiated because all the patients with positive repeat SNB underwent AD. For invasive luminal-like HER2-negative recurrences, the metastatic sentinel node was significantly associated with the choice to prescribe adjuvant chemotherapy (p = 0.003). CONCLUSIONS: In specialized centers, repeat axillary SNB for patients with local recurrence after mastectomy in the absence of previous AD can represent a safe option for detection and removal of occult axillary disease that would otherwise not be excised/irradiated to achieve better local control and could possibly influence the choice of adjuvant treatments.
