Abstract
On May 14, 2020, a 37 year old female patient with unilateral breast cancer was admitted to Hunan Cancer Hospital. She underwent modified radical mastectomy for right breast cancer and free transplantation of bilateral superficial inferior epigastric artery perforator flap (weighed 305 g) for breast reconstruction. During the operation, the right inferior epigastric vascular pedicle was anastomosed with the proximal end of the right internal mammary vessel, and the left inferior epigastric vascular pedicle was anastomosed with the distal end of the right internal mammary vessel; the blood flow of the flap was good; the wound in the donor site of the abdominal flap was closed directly. The operation lasted for 9 hours. In the first 48 hours post operation, the flap showed mild elevation in perfusion over drainage, but no obvious edema or blister was observed, flap temperature was consistent with the surrounding skin, and the drainage volume out of drainage tube was only 40 mL. The blood supply of the flap was completely restored to normal 3 days post operation, the flap survived well, the donor site incision had no obvious tension, and the healing was smooth. After 2 months of follow-up, the donor site incision of abdomen healed completely, only linear scar was left, and the reconstructed breast had a natural appearance; the patient planned to perform further nipple reconstruction and contralateral breast mastopexy. This case suggests that autologous breast reconstruction can be performed using bilateral superficial inferior epigastric artery perforator flaps under certain circumstances to minimize donor site injury to the greatest extent.

Abstract
BACKGROUND The management of physical symptoms and psychological distress of cancer patients is an important component of cancer care. The purpose of this study was to evaluate the symptom burden, psychological distress, and management status of hospitalized patients with advanced cancer in China and explore the potential influencing factors of undertreatment and non-treatment of symptoms. PATIENTS AND METHODS A total of 2930 hospitalized patients with advanced cancer (top six types of cancer in China) were recruited from 10 centers all over China. Patient-reported MD Anderson Symptom Inventory, Hospital Anxiety and Depression Scale (HADS), and Patient Health Questionnaire-9 (PHQ-9) scales and symptom management-related information were collected and linked with the patient's clinical data. The proportion of patients reporting moderate-to-severe (MS) symptoms and whether they were currently well managed were examined. Multivariable logistic regression models were applied to explore the factors correlated to undertreatment and non-treatment of symptoms. RESULTS About 27% of patients reported over three MS symptoms, 16% reported over five, and 9% reported over seven. Regarding psychological distress, the prevalence of HADS-anxiety was 29% and that of PHQ-9 depression was 11%. Sixty-one percent of patients have at least one MS symptom without any treatment. Sex [odds ratio (OR) = 2.238, 95% confidence interval (95% CI) 1.502-3.336], Eastern Cooperative Oncology Group (ECOG; OR = 0.404, 95% CI 0.241-0.676), and whether currently undergoing anticancer treatment (OR = 0.667, 95% CI 0.503-0.886) are the main factors correlated with the undertreatment of symptoms. Age (OR = 1.972, 95% CI 1.263-3.336), sex (OR = 0.626, 95% CI 0.414-0.948), ECOG (OR = 0.266, 95% CI 0.175-0.403), whether currently undergoing anticancer treatment (OR = 0.356, 95% CI 0.249-0.509), and comorbidity (OR = 0.713, 95% CI 0.526-0.966) are the main factors correlated with the non-treatment of symptoms. CONCLUSIONS This study shows that hospitalized patients with advanced cancer had a variety of physical and psychological symptoms but lacked adequate management and suggests that a complete symptom screening and management system is needed to deal with this complex problem.

Abstract
The development of immunosensing assays for in vitro diagnostics has attracted great attention in recent years. Various substrate materials and immobilization methods of biomolecules were exploited for immunosensors, but their bioactivity and longevity have been facing serious challenges. To address this limitation, we investigated a natural silk cocoon membrane as immunosensing substrate material. By using its intrinsic properties, the target biomolecules were immobilized on the membrane through directional immunoaffinity recognition. The silk cocoon membrane-based immunosensor showed great potential for both qualitative and quantitative immunoassays, through naked-eye observation or analyzing the change in red color intensity, respectively. The immunosensor exhibited significant detection capability for anti-D (titer 1:1024) sensitized red blood cells. The colorimetric responses of concentrations ranged from 1 μg/mL to 1 ng/mL, and the detection limit for anti-D was 3.4 ng/mL. The immunosensor also showed excellent stability for the immobilized antibodies when stored at 4 and 25 °C; the bioactivity remained unchanged or slightly declined within 40 weeks. Even at 37 °C, the bioactivity began to decline after 12 weeks. This current work highlights the potential of using the natural silk cocoon membrane as a substrate for a versatile and thermally stable immunosensing platform for application in immunoassays.

Abstract
Objective: To explore the safety and feasibility of stereotactic radiation therapy (SBRT) strategy for irradiating porcine ventricular septum, see if can provide a preliminary experimental evidence for clinical SBRT in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: Five male pigs (39-49 kg, 6 months old) were used in this study. Pigs were irradiated at doses of 25 Gy (n=2) or 40 Gy (n=3). Delineation of the target volume was achieved under the guidance of 3-dimensional CT image reconstruction, and SBRT was then performed on defined target volume of porcine ventricular septum. Blood biomarkers, electrocardiogram and echocardiography parameters were monitored before and after SBRT. Pathological examination (HE staining, Masson staining) was performed on the target and non-target myocardium at 6 months post SBRT. Results: SBRT was successful and all animals survived to the designed study endpoint (6 months) after SBRT. Serum cardiac troponin T (cTnT) level was significantly higher than the baseline level at 1 day post SBRT, and reduced at 1 week after SBRT, but was still higher than the baseline level(P<0.05). Serum N-terminal pro-B type natriuretic peptide (NT-proBNP) was also significantly increased at 1 day post SBRT (P<0.05) and returned to baseline level at 1 week post SBRT. The serum NT-proBNP level was (249±78), (594±37) and (234±46) pg/ml, respectively, and the cTnT was (14±7), (240±40) and (46±34) pg/ml, respectively at baseline, 1 day and 1 week after SBRT in the 40 Gy dose group. The serum NT-proBNP level was (184±20), (451±49) and (209±36) pg/ml, respectively, the cTnT values were (9±1), (176±29) and (89±27) pg/ml, respectively at baseline, 1 day and 1 week after SBRT in the 25 Gy dose group. Both NT-proBNP and cTnT values tended to be higher post SBRT in the 40 Gy dose group as compared with the 25 Gy dose group, but the difference was not statistically significant (P>0.05). The left ventricular ejection fraction and the left ventricular end-diastolic diameter remained unchanged before and after SBRT (P>0.05). The interventricular septum thickness showed a decreasing trend at 6 months after SBRT, but the difference was not statistically significant ((9.54±0.24) mm vs. (9.82±8.00) mm, P>0.05). The flow velocity of the left ventricular outflow tract, and the valve function and morphology were not affected by SBRT. At 6 months after SBRT, HE staining revealed necrosis in the irradiated target area of the myocardium in the 40 Gy dose group and the 25 Gy dose group, and the degree of necrosis in the irradiated interventricular septum was more obvious in the 40 Gy dose group as compared with the 25 Gy group. The combined histological analysis of the two groups showed that the necrotic area of the irradiated target area accounted for (26±9)% of the entire interventricular septum area, which was higher than that of the non-irradiated area (0) (P<0.05). There was no damage or necrosis of myocardial tissue outside the target irradiation area in both groups. The results of Masson staining showed that the percentage area of myocardial fibrosis was significantly higher in the irradiated target area than non-irradiated area ((12.6±5.3)% vs. (2.5±0.8)%, P<0.05). Conclusion: SBRT is safe and feasible for irradiating porcine ventricular septum.

Abstract
Quantitative testing of BK virus (BKPyV) nucleic acid has become the standard of care in transplant patients. While the relationship between interassay harmonization and commutability has been well characterized for other transplant-related viruses, it has been less well studied for BKPyV, particularly regarding differences in commutability between matrices. Here, interassay agreement was evaluated among six real-time nucleic acid amplification tests (NAATs) and one digital PCR (dPCR) BKPyV assay. Differences in the commutability of three quantitative standards was examined across all assays using a variety of statistical approaches. Panels, including 40 samples each of plasma and urine samples previously positive for BKPyV, together with one previously negative plasma sample and four previously negative urine samples, were tested using all assays, with each real-time NAAT utilizing its usual quantitative calibrators. Serial dilutions of WHO, National Institute for Standards and Technology (NIST), and commercially produced (Exact/Bio-Rad) reference materials were also run by each assay as unknowns. The agreement of the clinical sample values was assessed as a group and in a pairwise manner. The commutability was estimated using both relativistic and quantitative means. The quantitative agreement across assays in the urine samples was within a single log10 unit across all assays, while the results from the plasma samples varied by 2 to 3 log10 IU/mL. The commutability showed a similar disparity between the matrices. Recalibration using international standards diminished the resulting discrepancies in some but not all cases. Differences in the sample matrix can affect the commutability and interassay agreement of quantitative BKPyV assays. Differences in commutability between matrices may largely be due to factors other than those such as amplicon size, previously described as important in the case of cytomegalovirus. Continued efforts to standardize viral load measurements must address multiple sources of variability and account for differences in assay systems, quantitative standards, and sample matrices.

Abstract
INTRODUCTION Linezolid is a synthetic oxazolidinone antimicrobial drug with a broad spectrum and a unique mechanism of inhibiting resistant pathogenic strains, and it was approved by the Food and Drug Administration (FDA) in April 2000. Several different systemic side effects were reported after the use of this medication. In this article, we report a case in which a syndrome of inappropriate antidiuretic hormone (SIADH) was developed after linezolid treatment was started. CASE PRESENTATION We present the case of a 79-year-old woman who developed severe hyponatremia during linezolid treatment (0.6 g i.v. q12 h) after undergoing hemiarthroplasty for left femoral neck fracture. The patient's baseline serum sodium upon admission (138 mmol/L) decreased to 118 mmol/L, urine sodium was 102 mmol/L, plasma osmolality was 248 mOsm/kg and urine osmolarity was 310 mOsm/kg at day 4, thus a diagnosis of SIADH was made. The patient was not taking any other medication known to cause SIADH, and she did not present a comorbidity that could explain her condition. Her serum sodium increased to 135 and 137 mmol/L, respectively, 11 and 12 days after cessation of linezolid, strongly suggesting that SIADH was the cause in this case. CONCLUSIONS This is the fourth case of linezolid-induced SIADH. A thorough workup was essential for the diagnosis to correctly differentiate between SIADH and other causes of hyponatremia, which helped us properly conducting follow-up treatments. SIADH is a rare but serious side effect of linezolid, and practicing physicians should be aware of this complication. It is necessary to periodically monitor the serum sodium.

Abstract
Abstract
Study question
Are paternal serum free thyroxine (FT4) concentrations within the reference range associated with outcomes of assisted reproductive technologies (ART)?
Summary answer
Men of older reproductive age (≥ 35 years old) with low FT4 concentrations within the reference range are associated with a decreased live birth rate.
What is known already
The impact of maternal thyroid dysfunction on ART outcomes has been widely elucidated. However, few studies have investigated the impact of paternal thyroid dysfunction on ART outcomes. Our previous study showed a detrimental impact of paternal subclinical hypothyroidism (SCH) on the clinical outcomes of ART. Patients with SCH had relatively lower concentrations of FT4 compared to those with euthyroidism. Therefore, it remains to be determined whether the detrimental impacts of paternal SCH on ART outcomes arise from low concentrations of FT4.
Study design, size, duration
This retrospective cohort study included 4,066 couples who received 4,894 ART treatment cycles in our clinic between 1 April 2016 and 31 August 2021.
Participants/materials, setting, methods
The differences in sperm parameters and ART outcomes across the paternal FT4 tertiles were compared using generalised linear models or generalised estimation equation models. The primary outcomes were the clinical pregnancy rate (CPR) and live birth rate (LBR), and the secondary outcomes were sperm parameters, fertilisation rate, good-quality embryo rate, blastocyst formation rate, and implantation rate.
Main results and the role of chance
The mean ages of the males and their female partners were 33.0 and 31.0 years, respectively. No significant differences are observed in the sperm parameters and ART outcomes across the paternal FT4 tertiles in the overall population. However, stratified analysis of men aged ≥ 35 shows a non-significantly lower CPR in the lower paternal FT4 tertile (adjusted rate: 0.36, 95% CI: 0.27–0.45) relative to the middle (adjusted rate: 0.45, 95% CI: 0.38–0.53) and upper (adjusted rate: 0.43, 95% CI: 0.36–0.51) tertiles. The adjusted LBR is 0.21 (95% CI: 0.15–0.30) for men aged ≥ 35 in the lower FT4 tertile (p = 0.024, with reference to the upper tertile), 0.27 (95% CI: 0.21–0.35) for those in the middle tertile and 0.30 (95% CI: 0.23–0.38) for those in the upper tertile. No differences in these outcomes are seen among men aged < 35. The nonlinear smoothing curve obtained by using FT4 as a continuous variable further supports these findings.
Limitations, reasons for caution
Due to the retrospective design of the study, a causal relationship between paternal FT4 concentrations and ART outcomes could not be established. In addition, the study participants were patients who sought fertility treatment, which may have biased the results when we analysed the associations between FT4 concentrations and sperm parameters.
Wider implications of the findings
These results suggest that in older men, low paternal FT4 concentrations, although within the reference range, are associated with worse ART outcomes, especially LBR. Future prospective studies are warranted to confirm the detrimental effects of low paternal FT4 concentrations on ART outcomes.

Abstract
Single-arm trial refers to a clinical trial design that does not set up parallel control group, adopts open design, and does not involve randomization and blind method. These features, on the one hand, speed up the process of clinical trials, significantly shorten the time to market and meet the needs of patients with advanced malignancies, but also lead to the uncertainty of single-arm clinical trials themselves. Recently, the US Food and Drug Administration held a meeting of the oncologic drug advisory committee to discuss six tumor indications that have been accelerated approved, which once again triggered the discussion of single-arm trials. The basis of accelerated approval by single-arm trial is actually a compromise on the level of evidence-based medical evidence requirements after assessing the benefit risk. Therefore, the sponsor should strictly grasp the applicable conditions of single-arm trial in anti-tumor drugs and conduct single-arm trial scientifically. Post-marketing clinical trial should be implement as early as possible to ensure the benefit of patients. Based on the characteristics of single-arm trial, combined with two guidance relevant to single-arm trial issued by National Medical Products Administration recently, this article is supposed to propose and summarize the strategy of single-arm trial supporting the marketing of anti-tumor drugs.

Abstract
AIM To develop and validate a radiomics nomogram for prediction of degree of differentiation in lung adenocarcinoma presenting as sub-solid or solid nodules. MATERIALS AND METHODS A total of 438 patients with histopathologically confirmed adenocarcinoma (248 non-poorly differentiated and 190 poorly differentiated) were divided into training cohort (n=235) and internal validation cohort (n=203) according to surgery sequence. Sixty patients form public TCIA dataset were selected for external validation. One thousand, two hundred and eighteen radiomics features were extracted from each volumetric region of interest and a least absolute shrinkage and selection operator logistic regression was applied to select meaningful radiomic features for building a radiomics score (Rad-score) model. A nomogram model incorporating the Rad-score and type was established after multivariable logistic regression. The discrimination efficiency, calibration efficacy, and clinical utility value of the nomogram were evaluated. RESULTS The Rad-score model could predict the differentiation degree of lung adenocarcinoma with an area under the curve (AUC) of 0.83 (95% confidence interval [CI]: 0.78-0.89) in the internal validation cohort. The AUC of the nomogram and radiographic model was 0.86 (95% CI: 0.80-0.91), 0.78 (95% CI: 0.72-0.84) in the internal validation cohort respectively. The AUC of the nomogram in the external validation cohort was 0.73 (95% CI: 0.58-0.88). Delong's test showed that the nomogram performed better than radiographic features alone (p=0.001). CONCLUSIONS The proposed radiomics nomogram has the potential to predict the differentiation degree of lung adenocarcinoma preoperatively.

Abstract
BackgroundOligoarticular psoriatic arthritis (PsA) is commonly reported in early disease. Although fewer joints are involved, there may be significant impact on patients’ (pts) quality of life. The ongoing FOREMOST study (NCT03747939) is investigating the efficacy of apremilast vs placebo for treatment of early oligoarticular PsA (>1 but ≤4 tender and swollen joints involved).ObjectivesTo characterize disease burden in pts with early oligoarticular PsA and disease phenotype including location and size of involved joints and presence of certain baseline clinical PsA manifestations in FOREMOST pts.MethodsBaseline swollen and tender joint distribution was analyzed. Baseline disease burden was assessed in the overall group and a subgroup with small joint involvement only (for context) using clinical disease activity measures, pt-reported outcomes, and additional PsA manifestations.ResultsAt data cut-off for analysis, 220 pts of 285 planned were enrolled. In the overall group, disease duration was <1 year and joint distribution for swollen or tender joints involved predominantly small joints, with ~48% of joint involvement observed in finger proximal interphalangeal (PIP) joints and <2% in temporomandibular and clavicular joints across swollen or tender joints (Figure 1). Mean Physician’s and Patient Global Assessment of Disease Activity (PhGA and PtGA, respectively) scores were 43.9 and 51.3; mean pt pain assessment score was 50.7. Mean Health Assessment Questionnaire Disability Index (HAQ-DI) functional assessment score was 1.0; 25.5% of pts had HAQ-DI ≤0.5. Pts reported an average PsA Impact of Disease (PsAID-12) domain score of 4.7. Additional manifestations of PsA at baseline included dactylitis (14.5%), enthesitis (32.7%), nail involvement (67.3%), and skin disease (47.7% with body surface area [BSA] ≥3%). Within the overall group, 59% had >1 joint size involved (small [metacarpophalangeal, metatarsophalangeal, distal interphalangeal, PIP, hand carpometacarpal and mid-tarsal]; intermediate [wrist, elbow, ankle, temporomandibular, acromioclavicular, sternoclavicular]; large [shoulder, hip, knee]). Of those with only 1 joint size involved (41% of pts), the majority had small joint involvement predominantly in PIPs (n=84 for small joints; n=1 for intermediate joints; n=5 for large joints). The overall pattern of clinical and disease presentation indicated elevated burden for pts with early oligoarticular PsA, including those pts with only small joints involved (Table 1).Table 1.CharacteristicsOverall Population (PBO + APR), N=220Small Joints Only (PBO + APR), N=84Age, mean, y49.651.3Men, n (%)98 (44.5)40 (47.6)Europe/Russia, n (%)47 (21.4)/66 (30.0)22 (26.2)/11 (13.1)Canada/United States, n (%)8 (3.6)/99 (45.0)1 (1.2)/50 (59.5)Body mass index, mean, kg/m230.429.3Duration of disease, mean, y0.690.71Previous cDMARD use, n (%)143 (65.0)48 (57.0)Tender joint count (0–68), mean3.23.1Swollen joint count (0–66), mean2.62.8PhGA (VAS 0–100)a, mean43.939.0PtGA (VAS 0–100)a, mean51.345.6Patient’s Assessment of Pain (VAS 0–100)a, mean50.746.3Dactylitis present, n (%)32 (14.5)14 (16.7)Enthesitis present, n (%)72 (32.7)21 (25.0)BSA ≥3%, n (%)105 (47.7)34 (40.5)Nail involvement present, n (%)148 (67.3)53 (63.1)HAQ-DI (0–3)a, mean1.020.84HAQ-DI ≤0.5, n (%)56 (25.5)31 (36.9)PsAID-12 (0–10)a, mean4.733.98cDMARD, conventional disease-modifying antirheumatic drugs; VAS, visual analog scale.aHigher scores indicate greater burden/worse status.

Abstract
Objective: To analyze the clinical characteristics of Wilson's disease (WD) with onset of acute liver failure (ALF) in children. Methods: Clinical data of 19 children diagnosed with WD presented with ALF in Xi'an Children's Hospital from January 2016 to April 2021 were retrospectively analyzed, including general condition, clinical manifestation, laboratory examination, and gene detection. The children were divided into the death group and survival group according to the clinical outcome. The children who had hepatic WD with non-ALF onset during the same period were selected as the control. The general conditions and laboratory indexes were compared between death group and survival group, ALF group and non-ALF group. T-test, Mann Whitney U test or χ2 test were used to compare the differences between the two groups. Results: Of the 19 WD children with ALF onset, 10 were females and 9 were males. The age of admission was (10.1±2.6) years and time to onset of first visit was 9 (4, 15) days. Among the WD children with ALF onset, 4 children were lost to follow-up, 5 cases death (death group) and 10 cases survived (survival group). The ceruloplasmin in the death group was higher than that in the survival group (0.078 (0.055, 0.105) vs. 0.033 (0.027, 0.058) g/L, Z=-2.33, P=0.020). There were 95 children who had hepatic WD with non-ALF onset. The WD patients with ALF onset were older at admission (9.9 (8.0, 11.1) vs. 5.4 (3.7, 6.9) years, Z=-5.25, P<0.001), had higher ceruloplasmin (0.060 (0.030, 0.078) vs. 0.024 (0.006, 0.060) g/L, Z=-3.11, P=0.002), 24 h urinary copper (674 (205, 1 803) vs. 149 (108, 206) μg, Z=-4.25, P<0.001), and positive rate of K-F ring [17/19 vs. 7%(7/95), χ2=50.17, P<0.001] while shorter onset time at initial visit (0.3 (0.1, 0.5) vs. 1.0 (0.7, 6.0) months, Z=-4.28, P<0.001). There was no gender difference between the two groups [9/19 vs. 61%(58/95), χ2=1.22, P=0.269]. Of the 19 WD children with ALF onset, 13 had the ATP7B gene tested, and 15 reported variants were detected. The main variations were c.2333G>T (p. Arg778Leu), c.2621C>T (p. Ala874Val) and c.2975C>T (p. Pro992Leu). The allele frequencies were 6/26(23%), 4/26(15%) and 3/26(12%), respectively. Conclusions: Children of WD onset with ALF are school-aged and above. They have an acute onset, a short course of the disease, and poor prognosis. The positive rate of K-F ring, ceruloplasmin and urinary copper are higher than those of the hepatic WD children with non-ALF onset.

Abstract
We report precision determinations of the beam-normal single spin asymmetries (A_{n}) in the elastic scattering of 0.95 and 2.18 GeV electrons off ^{12}C, ^{40}Ca, ^{48}Ca, and ^{208}Pb at very forward angles where the most detailed theoretical calculations have been performed. The first measurements of A_{n} for ^{40}Ca and ^{48}Ca are found to be similar to that of ^{12}C, consistent with expectations and thus demonstrating the validity of theoretical calculations for nuclei with Z≤20. We also report A_{n} for ^{208}Pb at two new momentum transfers (Q^{2}) extending the previous measurement. Our new data confirm the surprising result previously reported, with all three data points showing significant disagreement with the results from the Z≤20 nuclei. These data confirm our basic understanding of the underlying dynamics that govern A_{n} for nuclei containing ≲50 nucleons, but point to the need for further investigation to understand the unusual A_{n} behavior discovered for scattering off ^{208}Pb.

Abstract
The ratio of the nucleon F_{2} structure functions, F_{2}^{n}/F_{2}^{p}, is determined by the MARATHON experiment from measurements of deep inelastic scattering of electrons from ^{3}H and ^{3}He nuclei. The experiment was performed in the Hall A Facility of Jefferson Lab using two high-resolution spectrometers for electron detection, and a cryogenic target system which included a low-activity tritium cell. The data analysis used a novel technique exploiting the mirror symmetry of the two nuclei, which essentially eliminates many theoretical uncertainties in the extraction of the ratio. The results, which cover the Bjorken scaling variable range 0.19<x<0.83, represent a significant improvement compared to previous SLAC and Jefferson Lab measurements for the ratio. They are compared to recent theoretical calculations and empirical determinations of the F_{2}^{n}/F_{2}^{p} ratio.

Abstract
Abstract
Aim
Non-melanoma skin cancers (NMSC) are the most common malignancies worldwide, with basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs) constituting an ever-growing clinical burden within Plastic & Reconstructive Surgery. In this 3-cycle Quality Improvement (QI) initiative we sought to evaluate and improve our unit’s compliance with British Association of Dermatology (BAD) guidance on excision margins for NMSCs.
Method
Following results from two Plan-Do-Study-Act (PDSA) cycles, a third retrospective review of clinic letters, operative notes and histopathology reports was undertaken to identify NMSCs that were excised during May 2021 and assess compliance with recommended excision margins according to risk stratification.
Results
The dissemination of cycle 1 findings at departmental meetings, as well as the implementation of guideline posters and operative note templates conferred a significant improvement in both clinical documentation (12% to 100%) and local compliance with excision margin guidelines for BCCs (53% to 71%) and SCCs (50% to 79%). Following the adoption of new BAD guidelines on SSC margins in early 2021, a third cycle comprising 42 lesions demonstrated a sustained improvement in clinical documentation (100%) after a 7-month period and similar guideline compliance rates for both BCC (67%) and SCC (78%).
Conclusions
Adequate excision margins in cutaneous malignant pathology are vital to ensure complete removal, thus minimising the risk of recurrence. Although improvement across the PDSA cycles has been sustained despite the introduction of new SCC margin guidelines, we aim to introduce further interventions such as a knowledge and practice survey to continue improving excision margin compliance.
