RESUMO
BACKGROUND: There is a growing body of evidence suggesting that endocervical crypt involvement by high-grade cervical intraepithelial neoplasia (CIN) may represent a risk factor for disease recurrence after cervical treatment. OBJECTIVES: To provide a systematic review and meta-analysis on whether endocervical crypt involvement by high-grade CIN on the excised cervical specimen is associated with high-grade histopathological recurrence during the follow-up of women after cervical excisional treatment. SEARCH STRATEGY: We searched the Medline, Scopus, Central, and Clinical Trials.gov databases from inception till May 2023. SELECTION CRITERIA: Studies that reported on women with a single cervical treatment with any method of excision for CIN2 or CIN3 lesion, negative excision margins, and whose recurrence was defined histopathologically were included. DATA COLLECTION AND ANALYSIS: Two reviewers independently evaluated study eligibility. We used the fixed effects model for meta-analysis. MAIN RESULTS: There were 4 eligible studies included in the present systematic review that evaluated 1088 women treated with either large loop excision of the transformation zone (LLETZ) or with cold knife conization (CKC). We found no significant association of endocervical crypt involvement by CIN2-3 with high-grade histopathological recurrence at follow-up after cervical excision (OR 1.93; 95% CI 0.51-3.35). The subgroup analysis of women with LLETZ cervical excision showed again no significant association with high-grade histopathological recurrence at follow-up (OR 2.00; 95% CI 0.26-3.74). CONCLUSION: Endocervical crypt involvement by high-grade CIN does not seem to be a risk factor for high-grade histopathological recurrence after cervical excision with negative excision margins.

INTRODUCTION: Paget disease is a rare neoplasm of the skin that mainly involves the vulvar region. Vulvar Paget's disease (VPD) can spread beyond the apparent edges of the lesion resulting in a high risk of involved surgical margins. Our aim is to verify the efficacy of a preoperative vulvo-vaginal intensive clock mapping in the prediction of the invasiveness and the extension of VPD. MATERIALS AND METHODS: All consecutive patients with primary VPD referred to our institution from July 2005 to December 2018 were subjected to a preoperative intensive biopsy mapping (clock mapping) of the vulvo-vaginal area: inside and outside the vulvar skin visible lesion, according to o'clock positions, and in the vagina. Patients with positive biopsies "only inside" or "also beyond" the visible lesion were included, respectively, in Group A and B. Surgical excision was drawn passing by the points with negative histology. Pathological findings of mapping biopsies were compared with those from radical surgery. RESULTS: A total of 28 women were enrolled. After clock mapping definitive histology: 17 (60.7%) and 11 (39.3%) patients were included in Group A and B. Definitive histology showed non-invasive, micro-invasive and invasive VPD, respectively, in 13 (46.4%), 11 (39.3%) and 4 (14.3%) patients, with 4 patients further upstaged. Overall, negative margins were found in 14 (50%) patients: 9 (32.1%) from Group A and 5 (17.9%) from Group B. In 23 cases (82.1%), clock mapping identified free surgical margins along the vulvo-perineal skin excision front. CONCLUSIONS: Preoperative clock mapping emerged as potentially useful workup tool to predict invasiveness and extension of VPD, to tailor surgical excision.

BACKGROUND: Microscopic evaluation of the entire surgical margin during excision of cutaneous malignancies results in the highest rates of complete excision and lowest rates of true local scar recurrence. Few studies demonstrate the outcomes of Mohs micrographic surgery specifically for invasive melanoma of the trunk and proximal portion of the extremities. OBJECTIVE: To evaluate the long-term efficacy of Mohs micrographic surgery for invasive melanoma of the trunk and proximal portion of the extremities, including true local scar recurrence rate, distant recurrence-free survival, and disease-specific survival. METHODS: Prospectively collected study of 1416 cases of invasive melanoma of the trunk and proximal portion of the extremities was performed to evaluate long-term outcomes. RESULTS: True local scar recurrences occurred in our cohort at a rate of 0.14% (2/1416), after a mean follow-up period of 75 months and were not associated with tumor depth. The rate of satellite/in-transit recurrences and the disease-specific survival stratified by tumor thickness were superior to historical control values. LIMITATIONS: We used a nonrandomized, single institution, retrospective design. CONCLUSIONS: Mohs micrographic surgery of primary cutaneous invasive melanoma on the trunk and proximal portion of the extremities resulted in local control of 99.86% of tumors and an overall disease-specific death rate superior to that of wide local excision.

BACKGROUND: Single-institution studies show that frozen section Mohs micrographic surgery (MMS) is an effective treatment modality for cutaneous melanoma, but no multi-institutional studies have been published. OBJECTIVE: To characterize the use of MMS in the treatment of melanoma at 3 academic and 8 private practices throughout the United States, to recommend excision margins when 100% histologic margin evaluation is not used, and to compare actual costs of tumor removal with MMS vs standard surgical excision. METHODS: Prospective, multicenter, cohort study of 562 melanomas treated with MMS with melanoma antigen recognized by T cells 1 immunostaining. RESULTS: Primary trunk and extremity melanomas (noninvasive and invasive melanoma) achieved histologically negative margins in 97% of tumors with 10-mm margins, whereas 12-mm margins were necessary to achieve histologically negative margins in 97% of head and neck melanomas. Overall average cost per tumor treated was $1328.46. LIMITATIONS: Nonrandomized and noncontrolled study. CONCLUSIONS: MMS with melanoma antigen recognized by T cells 1 immunostaining safely provides tissue conservation and same-day reconstruction of histologically verified tumor-free margins in a convenient, single-day procedure. When comprehensive margin evaluation is not used, initial surgical margins of at least 10 mm for primary trunk/extremity and 12 mm for head/neck melanomas should be used to achieve histologically negative margins 97% of the time.

OBJECTIVE: To define molecular differences between autofluorescence and white light defined excision margins in oral potentially malignant disorders (OPMD) using transcriptome expression profiles. MATERIALS AND METHODS: Excisional biopsy specimens were taken from 11 patients at three different sites for each lesion: centre, white light margin and autofluorescence margin. The lesions were diagnosed histopathologically as oral epithelial dysplasia, oral lichenoid dysplasia, oral lichen planus or other. Transcriptome analysis was performed by RNA sequencing, hierarchical clustering, differential expression and biological pathway analysis. RESULTS: For hierarchical clustering, the samples broadly clustered according to histology rather than the margins with lichenoid samples clustering together. Differential expression analysis showed that independent of histology, there was greater molecular dysregulation between the lesion centre and autofluorescence margin compared to the lesion centre and white light margin. Furthermore, the autofluorescence and white light margins were molecularly distinct, indicating the white light margins harboured abnormality. CONCLUSION: Our results indicate that the molecular profile of OPMD changes with divergence away from the centre of the lesion, and that autofluorescence determined margins are superior to the white light margin in achieving a clear molecular margin when excising an OPMD.

BACKGROUND: Evaluation of the entire surgical margin results in high rates of complete excision, low local recurrence rates, and maximal tissue conservation. Although well recognized for melanoma of the head and neck, few studies have focused exclusively on the trunk and proximal extremities. OBJECTIVE: We sought to evaluate the efficacy of Mohs micrographic surgery for melanoma in situ (MIS) of the trunk and proximal extremities, and determine adequate excision margins for MIS when total margin evaluation is not used. METHODS: Long-term outcomes in 882 cases of MIS treated with Mohs micrographic surgery were analyzed and compared with historical controls. Rates of complete excision were determined for increasing surgical margin intervals. RESULTS: One local recurrence occurred in our cohort (0.1%). Only 83% of MIS were excised with a 6-mm margin. Margins of 9 mm were needed to excise 97% of MIS, statistically equivalent to thin melanomas. LIMITATIONS: We used a nonrandomized, single-institution, retrospective design. CONCLUSION: Mohs micrographic surgery may cure the 17% of MIS that exceed traditional excision margins of 5 mm and is a valuable option for these patients. Surgical margins of at least 0.9 cm should be considered for MIS of the trunk and extremities when total margin evaluation is not used.

The objective of our study was to determine whether removing multiple pieces of cervical tissue during large loop excision of the transformation zone (LLETZ) reduced the margin positivity of excision and cytology recurrence rates at follow-up. We conducted an observational cohort study and identified 462 women having had a single LLETZ treatment for cervical intraepithelial neoplasia (CIN) over a two-year period. Women with previous cervical treatment, cervical cancer on the excised tissue or missing follow-up data were excluded. Multiple regression analysis showed that removal of cervical tissue in multiple pieces did not offer any benefit in removing more disease and less recurrence rates. When multiple pieces were taken there was a four-fold increased risk for inconclusive excision margins as reported by the histopathologist. Removal of multiple pieces led to significantly more tissue being removed which may expose the patient to an increased risk of preterm delivery in a future pregnancy.

BACKGROUND AND OBJECTIVES: Surgery is an essential treatment for non-distant metastatic cutaneous melanoma (NMCM). We aim to construct and validate prognostic nomograms based on surgical approaches and the clinicopathological characteristics of NMCM patients. METHODS: Data of patients diagnosed with cutaneous melanoma from 2004 to 2015 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Two online nomograms were constructed to predict the 3, 5-year melanoma-specific survival (MSS) for NMCM patients based on the surgical approaches. These nomograms were evaluated by the dynamic Harrell's concordance index (C-index), decision curve analysis and clinical impact curve. Both internal and external data verification were conducted. RESULTS: A total of 14,091 NMCM cases were included in this study. The C-index of the nomograms for the excisional surgery group and amputation group were 0.818 and 0.806, respectively, and 0.763 and 0.731, respectively, in our hospital data validation. After internal and bootstrap verification, our two nomograms showed good accuracy and practicality. CONCLUSION: NMCM patients exhibited equal survival rates independent of resection margin size, while those who needed amputation had worse survival rates. We generated two online nomograms distinguished by surgical approach to predict NMCM patient survival based on clinicopathological characteristics.

Although wide local excision is the standard treatment for primary melanoma, the surgical margin remains controversial. Melanomas of the head and neck exhibit higher recurrence rates and worse prognosis than lesions in other body locations, and their close proximity to critical anatomical and functional structures means that wide excision margins are often not feasible. Surgeons must therefore achieve a balance of oncological safety and functional and aesthetic needs. The aim of this study was to retrospectively analyse melanoma data over a 12-year period at a large skin surgery unit to identify potential differences in outcomes in patients who had reduced wide local excision margins for primary head and neck melanoma. The study would provide further evidence for the need for large randomised prospective trials to reduce excision margins for head and neck melanoma. Local cancer network data were retrospectively analysed over a period of 12 years (2008-2019). Data included site, initial stage, multidisciplinary team (MDT) meeting recommendations for excision margins and the actual wide local excision margin taken, recurrence rate, and disease-specific and absolute survival. A total of 222/305 patients (73%) had the recommended excision margin, while in 27% margins were reduced due to anatomical or functional considerations. Recurrence rates were similar (recommended 11.7% vs narrow 13.3% excision margins) (p = 0.64). The mean follow-up time for all patients was 48.5 months. In aesthetically and functionally sensitive areas of the head and neck, wide local excision margins need to be carefully considered after MDT discussion and discussion with the patient. This study suggests the need for further multicentre trials to address the uniqueness of head and neck melanoma.

Background: The relationship between endocervical and ectocervical margin status and residual or recurrence after cervical intraepithelial neoplasia (CIN) resection has been controversial. We investigated the relationship between the excision margins and residual/recurrence to assess indicators for the scope of resection and the risk of treatment failure by using meta-analysis. Methods: Literature searches were performed in PubMed, Medline, Embase, Central, Wangfang and CNKI databases. Patients after CIN resection were grouped according to whether there was residual or recurrence, and the differences in exposure factors between the two groups were compared. Or they were grouped by exposure factor, and compare the differences in residual and recurrence rates under different grouping conditions. The observed outcome was postoperative residual or recurrence. The risk of bias in the literature was assessed using the Newcastle-Ottawa Scale (NOS). The chi-square test were used for heterogeneity. Subgroup explored the sources of heterogeneity. Publication bias was assessed using funnel plots and Egger's test. Results: A total of 11 studies were included in this study, 8 studies were at low risk of bias and 3 studies were at high risk of bias. The 11 studies included 3065 patients, 774 patients with positive margins and 2,291 patients with negative margins. The rate of residual/recurrence after excision of CIN in patients with positive margins was significantly higher than in patients with negative margins [odds ratio (OR) =3.99, P<0.00001]. There was no heterogeneity among the studies (P=0.16), with publication bias (P<0.05). The residual/recurrence rate was significantly higher in patients with positive endocervical margins than in patients with negative endocervical margins (OR =2.59, P<0.00001). There was no heterogeneity among studies (P=0.78) and no publication bias (P<0.05). There was no significant difference in residual/recurrence rate between positive and negative ectocervical margins (OR =1.14, P=0.36). There was no heterogeneity among studies (P=0.32) and no publication bias (P<0.05). Conclusions: Positive endocervical margins, but not external cervical margins, are risk factors for residual/recurrence of CIN after resection. Close attention to the status of the endocervical margins is recommended. More aggressive treatment and frequent follow-up are needed for patients with positive endocervical margins.
RESUMO
BACKGROUND: A cohort study of patients, who underwent cutaneous squamous cell carcinoma (SCC) excision, was undertaken to evaluate the effects of the COVID-19 pandemic on treatment times and histopathological features. METHODS: We identified all patients who had SCCs excised in October 2020 (pandemic group); the control group included all patients who underwent excision of SCCs during October 2019 (pre-pandemic group). Collected data included SCC subtype, thickness, size, clearance margins, referral details, patient comorbidities and operative data. RESULTS: There were 140 patients (174 SCCs; pre-pandemic group=74; pandemic group=100) identified for study inclusion. Both groups were well matched for age, sex, previous history of cancer, cutaneous SCC and histological subtype. There was a delay in median patient presentation time to the GP in the pandemic versus pre-pandemic group (106 days vs. 56 days, p <0.001); this led to a longer overall time to surgery (167 days vs. 110.5 days, p < 0.001). Pandemic group SCCs had larger median Breslow depths (4 mm vs. 3 mm, p = 0.01), a greater proportion of Clark's level 4 and 5 lesions (76.9% vs. 61.1%, p = 0.03), and a higher rate of high (20-40 mm) and very high (>40 mm) risk SCCs as defined by British Association of Dermatology diameter criteria (56.1% vs. 39.2%, p = 0.03), versus the pre-pandemic group. CONCLUSIONS: There was a 57-day median SCC treatment delay, and an associated development of higher risk SCCs by the time of surgery. Despite the challenges of a pandemic, patients should seek early consultation for suspicious skin changes, and healthcare systems should maintain skin cancer treatment pathways.

Background: Reliable evidence to guide the management of melanoma in situ (MIS) and minimize the risk of recurrence is lacking. Objective: To identify clinicopathological predictors of local recurrence (LR) in patients with MIS and evaluate long-term outcomes according to pathological excision margins. Methods: A case-control study of patients with MIS treated at a large Australian melanoma treatment center from January 2008 to December 2012 was undertaken. Clinicopathological characteristics of patients who developed LR and those who did not were compared. Results: LR developed in 34 of 1407 patients with MIS (2.5%). Median time to LR was 20 months. The primary lesion was removed with pathological margins <4 mm (P < .001) in 67.6 % of patients with LR. Four patients died of metastatic melanoma following LR. Comparing patients with pathological margins <4 mm and ≥4 mm, the former were older (>60y, P < .001), more frequently had MIS on the head or neck (P < .001), had a greater LR rate (P < .001), and had a higher mortality from all causes (P < .001). Limitations: Retrospective, single-institution study. Conclusions: Pathological margins of ≥4 mm should be considered for patients with MIS who are treated with standard surgical excision and assessed by examining serial slices taken from the formalin-fixed, paraffin-embedded specimen.
RESUMO
OBJECTIVE: To describe the laterally extended parametrectomy (LEP) surgical technique, emphasizing the main challenges of the procedure. METHODS: LEP was designed as a more radical surgical procedure aiming to remove the entire parametrial tissue from the pelvic sidewall. Its initial indications were for lymph node positive Stage Ib (current International Federation of Gynecology and Obstetrics 2018 Stage IIIc) and Stage IIb cervical cancer. Currently, with most guidelines recommending definitive radiochemotherapy for these cases, initial LEP indications have become debatable. LEP is now mainly indicated for removing tumors involving the soft structures of the pelvic sidewall during a pelvic exenteration, aiming to obtain lateral free margins. This expands the lateral borders of the dissection to not only the medial surface of internal iliac vessels, but also to the true limits of the pelvic sidewall. RESULTS: During LEP, the parietal and visceral branches of the hypogastric vessels are divided at the entry and exit level of the pelvis. Consequently, the entire internal iliac system is excised, and no connective or lymphatic tissue remain on the pelvic sidewall. The main technical challenges of LEP are caused by the difficulty in ligating large caliber vessels (internal iliac artery and vein) and the variable anatomic distribution of pelvic sidewall veins. CONCLUSION: LEP is a feasible technique for removing pelvic sidewall recurrences, aiming to obtain surgical free margins.
RESUMO
Basal cell carcinoma is one of the most common cancers in white people, with a continuous increase worldwide. Dermoscopy, a non-invasive technique, allows early diagnosis based on the presence of typical vascular structures, pigmented structures, and ulceration and the absence of specific melanocytic structures. Moreover, dermoscopy is useful in basal cell carcinoma management, enabling the differentiation between multiple histological subtypes, between pigmented and non-pigmented variants and allowing a more accurate assessment of surgical margins. After non-ablative therapies, dermoscopy allows the accurate detection of residual disease. The purpose of this review is to highlight the dermoscopic features encountered in basal cell carcinoma and to outline the role of dermoscopy for diagnosis and therapeutic response in this cancer.
RESUMO
In vivo cancer margin delineation during surgery remains a major challenge. Despite the availability of several image guidance techniques and intraoperative assessment, clear surgical margins and debulking efficiency remain scarce. For this reason, there is particular interest in developing rapid intraoperative tools with high sensitivity and specificity to help guide cancer surgery in vivo. Recently, several emerging technologies including intraoperative mass spectrometry have paved the way for molecular guidance in a clinical setting. We evaluate these techniques and assess their relevance for intraoperative surgical guidance and how they can transform the future of molecular cancer surgery, diagnostics, patient management and care.

BACKGROUND: For invasive primary cutaneous melanoma, wider excision is advocated to reduce local recurrence risk and improve patient outcomes. Excision detail is controversial, especially in intermediate- and high-risk primary melanoma (AJCC pT2-pT4). Guidance varies from sizes 1 to 3 cm (translating into large defects of 2-6 cm). The aim of this study was to determine the reconstructive and resource burden of wider excision margins (EMs). METHODS: Data analysis from our prospective database (2008-2017) included 1184 patients (563F:621 M) with cutaneous melanoma (pT1b-pT4b). Procedure tariff data were sourced from our financial services department. RESULTS: Two hundred twenty-nine patients had a narrower EM (1 cm) and 995 (80.7%) had a wider EM (2-3 cm). Reconstructive requirement significantly increased with a wider EM collectively (11.3% vs 29.3%, odds ratio (OR) = 3.2; p < 0.0001), in the extremities (15.2% vs 42.0%; p < 0.0001), and in the head and neck (H&N) (23.5 % vs 64.7%; p < 0.0001). Reconstruction significantly increased hospitalisation rates (26.6% vs 63.0%, OR = 4.7; p < 0.0001) collectively, in the H&N (26.8 % vs 53.9%), and in the upper (18.9 % vs 42.3%) and lower extremities (34.8% vs 77.3%). Narrower EMs significantly reduced hospitalisation rates in the upper and lower extremities (7.1% vs 28.5%; pâ¯=â¯0.004, 37.9% vs 58.5%; pâ¯=â¯0.005, respectively). Overall procedure cost significantly increased by £180 (mean, p < 0.0001) and £346 (median, pâ¯=â¯0.0004) per patient when reconstruction was required. CONCLUSIONS: Our data suggest substantial impact of wider EM on patients, which more than doubled in the functionally and cosmetically sensitive extremities and the H&N region. Reconstructions add significant financial and healthcare service burden. Without randomised controlled trial (RCT) evidence demonstrating increased efficacy of wider EM, narrower EM is advocated whilst awaiting future planned RCT results specifically investigating on this.

INTRODUCTION: The secretory breast carcinoma is very rare in children. It represents less than 1% of malignancy cases in childhood and is even less common in males, with 15 cases reported until 2004. Therefore, the aim of this study is to report a male child with breast carcinoma and review literature. PRESENTATION OF CASE: A 14-year-old male patient with a history of a painless slow-growing lump in the left breast and, five years later, onset of yellow discharge from the papilla. Ultrasound scanning demonstrated a well- defined, regular, homogeneous and hypoechoic mass. Nodule excision was initially performed, followed by mastectomy, due to compromised radial margin. Immunohistochemistry revealed weakly positive estrogen and progesterone receptors. Adjuvant therapy was not required. Sixteen months after resection, the patient is well with no complaints or recurrence. DISCUSSION: Due to its rarity, there is no therapeutic guideline. Although the recommended treatment is still surgical excision, there is no consensus as to its extent. Prognosis is usually favorable. Our patient was submitted to mastectomy with sentinel lymph node biopsy due to compromised radial margin. CONCLUSION: Secretory breast carcinoma is a rare form of breast cancer, especially in male children; which hampers standardization of diagnosis, treatment and prognosis establishment.
RESUMO
AIM: Malignant melanoma is the fifth commonest invasive cancer in Ireland. The British Association of Dermatology (BAD) guidelines are currently the recognized standard for melanoma related surgery. The aim was to examine adherence to BAD guidelines and establish contributing factors resulting in non-adherence to guidelines in a group of melanoma patients in the South East Region of Ireland. METHODS: A retrospective review of a prospectively maintained melanoma registry of all patients undergoing surgery in the South East Region of Ireland from January 2011 to 2016 was performed. Data were analyzed using SPSS statistical software. Univariate analysis using logistic regression was performed to examine factors associated with not meeting the BAD margin excision guidelines Data with a p < 0.05 was analyzed using a multivariate logistic regression model. RESULTS: 459 patients underwent surgery for invasive cutaneous melanoma. 314 (68.4%) surgeries had excision margins adequately recorded and of these 234(74.5%) fulfilled the BAD guidelines. 267(58.2%) patients (2011-2016 inclusive) qualified for sentinel lymph node biopsy (SNLB) with a cancer staging of pT1b or higher. Of these patients 100(37%) agreed to proceed to a SNLB following informed discussion. 33 had a positive sentinel node. On multivariate analysis inadequate margins were independently associated with tumor thickness 2.01-4.00 mm (p = 0.0001) and >4.00 mm (p = 0.0001) and head and neck location (p < 0.0001). CONCLUSIONS: Adherence to BAD guidelines in the South East is good but requires optimization since centralization of melanoma treatment in 2013 to a single specialized center. It is important that Clinicians are fully aware of the implications of not achieving adequate excision margins in surgery. Improvements in melanoma data management is needed to fully evaluate current practices in Ireland.

Background: For patients who are diagnosed with early-stage cutaneous melanoma, the principal therapy is wide surgical excision of the primary tumour and assessment of lymph nodes. The purpose of the present guideline was to update the 2010 Cancer Care Ontario guideline on wide local excision margins and sentinel lymph node biopsy (slnb), including treatment of the positive sentinel node, for melanomas of the trunk, extremities, and head and neck. Methods: Using Ovid, the medline and embase electronic databases were systematically searched for systematic reviews and primary literature evaluating narrow compared with wide excision margins and the use of slnb for melanoma of the truck and extremities and of the head and neck. Search timelines ran from 2010 through week 25 of 2017. Results: Four systematic reviews were chosen for inclusion in the evidence base. Where systematic reviews were available, the search of the primary literature was conducted starting from the end date of the search in the reviews. Where systematic reviews were absent, the search for primary literature ran from 2010 forward. Of 1213 primary studies identified, 8 met the inclusion criteria. Two randomized controlled trials were used to inform the recommendation on completion lymph node dissection.Key updated recommendations include:â Wide local excision margins should be 2 cm for melanomas of the trunk, extremities, and head and neck that exceed 2 mm in depth.â slnb should be offered to patients with melanomas of the trunk, extremities, and head and neck that exceed 0.8 mm in depth.â Patients with sentinel node metastasis should be considered for nodal observation with ultrasonography rather than for completion lymph node dissection. Conclusions: Recommendations for primary excision margins, sentinel lymph node biopsy, and completion lymph node dissection in patients with cutaneous melanoma have been updated based on the current literature.
