RESUMO

OBJECTIVE: To evaluate the value of Wood's lamp examination combined with 5-aminolevulinic acid (5-ALA) photodynamic therapy (PDT) to determine positive tumor margins in patients with extramammary Paget's disease (EMPD) before surgery. METHODS: We admitted 36 patients with EMPD from January 2016 to June 2019. The experimental group was the 5-ALA-PDT group, and the control group was the wide local excision (WLE) group. In the 5-ALA-PDT group, Wood's lamp examination combined with 5-ALA-PDT was used to trace the fluorescence range, and multipoint biopsy was performed according to the pathology to determine the final excision scope. We applied the standard partial expansion excision method for the WLE group, while frozen pathology assessment was applied to confirm the excision range. We measured the overall resection area of the WLE group and 5-ALA-PDT group. We analyzed the overall duration of surgery, the number of frozen pathology sections, patient satisfaction with appearance and function, the rate of functional sequelae, and the recurrence rate for both groups. RESULTS: The results suggested that the difference in final resection margin between the WLE group and the 5-ALA-PDT group was significant. The number of frozen pathology sections, overall surgery time, and recurrence rate were significantly lower in the experimental group than in the control group (p<0.05). The occurrence rate of functional sequelae in the experimental group was lower, and patient satisfaction with appearance and function was significantly higher than that of the control group (p<0.05). CONCLUSION: Wood's lamp examination combined with 5-ALA-PDT may predict tumor margins in EMPD.

RESUMO

BACKGROUND: On average, 21% of women in the USA treated with Breast Conserving Surgery (BCS) undergo a second operation because of close positive margins. Tumor identification with fluorescence imaging could improve positive margin rates through demarcating location, size, and invasiveness of tumors. We investigated the technique's diagnostic accuracy in detecting tumors during BCS using intravenous indocyanine green (ICG) and a custom-built fluorescence camera system. METHODS: In this single-center prospective clinical study, 40 recruited BCS patients were sub-categorized into two cohorts. In the first 'enhanced permeability and retention' (EPR) cohort, 0.25 mg/kg ICG was injected ~ 25 min prior to tumor excision, and in the second 'angiography' cohort, ~ 5 min prior to tumor excision. Subsequently, an in-house imaging system was used to image the tumor in situ prior to resection, ex vivo following resection, the resection bed, and during grossing in the histopathology laboratory to compare the technique's diagnostic accuracy between the cohorts. RESULTS: The two cohorts were matched in patient and tumor characteristics. The majority of patients had invasive ductal carcinoma with concomitant ductal carcinoma in situ. Tumor-to-background ratio (TBR) in the angiography cohort was superior to the EPR cohort (TBR = 3.18 ± 1.74 vs 2.10 ± 0.92 respectively, p = 0.023). Tumor detection reached sensitivity and specificity scores of 0.82 and 0.93 for the angiography cohort and 0.66 and 0.90 for the EPR cohort, respectively (p = 0.1051 and p = 0.9099). DISCUSSION: ICG administration timing during the angiography phase compared with the EPR phase improved TBR and diagnostic accuracy. Future work will focus on image pattern analysis and adaptation of the camera system to targeting fluorophores specific to breast cancer.

RESUMO

BACKGROUND: To evaluate the clinicopathologic value of morphological growth patterns of small renal cell carcinoma (sRCC) and determine the actual demand for taking a rim of healthy parenchyma to avoid positive SM. METHODS: Data was collected from 560 sRCC patients who underwent laparoscopic surgeries from May 2010 to October 2017. One hundred forty-nine cases received nephron-sparing surgery (NSS) and others received radical nephrectomy (RN). All specimens were analyzed separately by two uropathologists, and three morphological growth patterns were identified. The presence of pseudocapsule (PC), surgical margins (SM), and other routine variables were recorded. The relationship between growth patterns and included variables was measured by the χ2 test and Fisher's exact probability test. Survival outcomes were evaluated by Kaplan-Meier method and the log-rank test. RESULTS: The median age of patients was 63.2 years old and the mean tumor diameter was 3.0 cm. Four hundred eighty (85.7%) cases were clear cell RCC and 541 (96.6%) cases were at the pT1a stage. Peritumoral PC was detected in 512 (92.5%) specimens, and the ratio of tumor invasion in PC in infiltration pattern increased obviously than that of the other growth patterns. Similarly, the pT stage was significantly correlated with the infiltration pattern as well. One hundred forty-nine patients underwent NSS and 3 (2.0%) of them showed positive SM after operation. Statistical differences of the 5-year overall survival (OS) and the cancer-specific survival (CSS) existed between different morphological growth patterns, PC status, and pT stages. CONCLUSIONS: Morphological growth patterns of sRCC might be used as a potential biomarker to help operate NSS to avoid the risk of positive SM. How to distinguish different morphological growth patterns before operation and the effectiveness of the growth pattern as a novel proposed parameter to direct NSS in sRCC patients deserves further exploration.

RESUMO

Breast-conserving surgery (BCS) has now become one of the optimal surgical choices for early invasive breast cancer. The pathological diagnosis of margin in breast-conserving specimen is very important. There is no acknowledge on the approaches of pathological biopsy and safety margin diagnosis of breast conserving surgery. This paper will compare the biopsy and diagnosis methods of breast-conserving surgery specimens between Tianjin Medical University Cancer Institute and Hospital in China and MD Anderson Cancer Center in the United States. We summarize our biopsy method and diagnostic criteria to explore how to accurately evaluate the margin of breast-conserving surgery specimen from a pathological point of view, and to escort a successful breast-conserving surgery.

RESUMO

BACKGROUND: We investigated the association between positive surgical margin (PSM) status and biochemical recurrence (BCR) after robot-assisted radical prostatectomy (RARP) to develop a prognostic factor-based risk stratification model for BCR. METHODS: We analyzed the data of 483 patients who underwent RARP at our hospital between October 2010 and April 2019; 435 patients without neoadjuvant therapy were finally included. The BCR-free survival rate was determined using Kaplan-Meier analysis. Effects of the PSM status, including the number of PSMs, Gleason score (GS) at a PSM, and the maximum PSM length for BCR, were investigated using Cox regression analysis. RESULTS: BCR was confirmed after RARP in 61 patients (14.0%), and PSM was confirmed in 74 patients (17.0%); PSM was a significant predictor of BCR (p < 0.001). The median number of PSMs was 2 (1-6), and the median maximum length of PSM was 6.0 (2.0-17.0) mm. Multivariable analysis showed lymph node invasion (p < 0.001), GS of ≥ 7 at a PSM (p = 0.022) and a maximum PSM length of > 6.0 mm (p = 0.003) were significant predictors of BCR. We classified the patients without lymph node invasion into good-, intermediate-, and poor-risk groups according to the other two risk factors (presence of 0, 1, and 2 factors, respectively) and rates of 1-year BCR-free survival (100.0, 72.7, and 48.1%, respectively). CONCLUSION: Higher GS at PSM and greater length of PSM were significant predictors of BCR after RARP, and console surgeons should be careful to prevent PSM during RARP.

RESUMO

Introduction: Simultaneous robot assisted colon and liver resections are being performed more frequently at present due to the expanded adoption of the robotic platform for surgical management of metastatic colon cancer. However, this approach has not been studied in detail with only case series available in the literature. The aim of this systematic review was to evaluate the current body of evidence on the feasibility of performing simultaneous robotic colon and liver resections. Methods: A systematic review was performed through PubMed to identify relevant articles describing simultaneous colon and liver resections for metastatic colon cancer. Results: A total of 28 patients underwent simultaneous resections robotically with an average operative time of 420.3 minutes and average blood loss of 275.6 ml. Postoperative stay was 8.6 days on average with all cases achieving negative surgical margins. Conclusions: Robotic simultaneous resection of colorectal cancer with liver metastases is technically feasible and seems oncologically equivalent to open or laparoscopic surgery. Further studies are urgently needed to assess benefits of robotic surgery in the patient population.

RESUMO

PURPOSE: To investigate the performance of magnetic resonance imaging (MRI)-based radiomics models for benign and malignant prostate lesion discrimination and extracapsular extension (ECE) and positive surgical margins (PSM) prediction. METHODS AND MATERIALS: In total, 459 patients who underwent multiparametric MRI (mpMRI) before prostate biopsy were included. Radiomic features were extracted from both T2-weighted imaging (T2WI) and the apparent diffusion coefficient (ADC). Patients were divided into different training sets and testing sets for different targets according to a ratio of 7:3. Radiomics signatures were built using radiomic features on the training set, and integrated models were built by adding clinical characteristics. The areas under the receiver operating characteristic curves (AUCs) were calculated to assess the classification performance on the testing sets. RESULTS: The radiomics signatures for benign and malignant lesion discrimination achieved AUCs of 0.775 (T2WI), 0.863 (ADC) and 0.855 (ADC + T2WI). The corresponding integrated models improved the AUC to 0.851/0.912/0.905, respectively. The radiomics signatures for ECE achieved the highest AUC of 0.625 (ADC), and the corresponding integrated model achieved the highest AUC (0.728). The radiomics signatures for PSM prediction achieved AUCs of 0.614 (T2WI) and 0.733 (ADC). The corresponding integrated models reached AUCs of 0.680 and 0.766, respectively. CONCLUSIONS: The MRI-based radiomics models, which took advantage of radiomic features on ADC and T2WI scans, showed good performance in discriminating benign and malignant prostate lesions and predicting ECE and PSM. Combining radiomics signatures and clinical factors enhanced the performance of the models, which may contribute to clinical diagnosis and treatment.

RESUMO

ABSTRACT: This study was to identify the predictors of recurrence in patients with high-grade cervical intraepithelial neoplasia (CIN) after cervical conization.Totally 415 patients with CIN ≥ II who underwent loop electrosurgical excision procedure (LEEP) or cold knife conization (CKC) were included in this retrospective study. Cox proportional hazards model was used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) regarding the association between postoperative recurrence and clinicopathological data.After the mean follow-up of (21.48 ±â€Š5.82) months, 90 (21.69%) out of 415 cases were subjected to recurrence after cervical conization. The influencing factors for postoperative recurrence included times of full-term birth, history of preterm birth, history of abortion, positive margin, cone length, width, depth, smoking, and history of complicating diseases (P < .05). Multivariate Cox model indicated the positive margin (HR = 2.144, 95% CI: 1.317-3.492, P < .05), history of preterm birth (HR = 4.515, 95% CI: 1.598-12.754, P < .05), history of complicating diseases (HR = 3.552, 95% CI: 1.952-6.462, P < .05) were independent risk factors for recurrence after cervical conization. The restricted cubic diagram showed that the cone depth >0.5 cm was a protective factor for postoperative recurrence.For the patients with high-grade CIN after cervical conization, positive margins, histories of preterm birth, and complicating diseases were associated with increased risk of recurrence, but cone depth (>0.5 cm) with lower risk of recurrence.

RESUMO

PURPOSE: The aim of this study is to present a single department's experience on cervical cancer cases following previous excision of cervical intraepithelial neoplasia (CIN) and to discuss potential pathogenesis. METHODS: Nine cervical cancer cases meeting the inclusion criteria, with available pathological and follow-up data, were considered eligible for this study. RESULTS: The majority (7/9) have had clear excisional margins. The interval between initial treatment and cancer diagnosis ranged from 7 to 17 years. In all cases cancer diagnosis was "unexpected", as the prior cytological and/or colposcopic evaluation was not suggestive of significant cervical pathology. All cancers were squamous, and 5/9 at stage I. CONCLUSION: The long interval between initial CIN treatment and final diagnosis as well as the normal post-treatment follow-up may suggest a 'de novo' underlying but 'hidden' carcinogenesis process. It might be that dysplastic cells entrapped within crypts (or normal metaplastic affected by the same predisposing factors) continue undergoing their evolution, undetectable by cytology and colposcopy until they invade stroma and surfaces (endo- and/or ectocervical) approximately a decade later. Heavy cauterisation of cervical crater produced post excision might be a potential culprit of this entrapment.

RESUMO

BACKGROUND: Variations in the anatomy of the hepatic artery are common. This study was aimed at sharing our experience with identifying and protecting the aberrant hepatic artery (AHA) and discussing its impact on the resection margin and outcomes of laparoscopic pancreatoduodenectomy (LPD). METHODS: A total of 576 patients who underwent LPD between 2015 and 2020 were retrospectively selected and divided into AHA and no AHA groups for this study. The demographics of the patients, pathological features, surgical data, and postoperative complications were further compared and analyzed between the two groups. RESULTS: The AHA group included 127 patients (22.05%). No statistically significant differences were found between the AHA and no AHA groups in the intraoperative data, postoperative complications, and long-term survival with malignant tumor. There was also no significant difference in the R1 rate for pancreatic adenocarcinoma. CONCLUSIONS: AHA appears frequently; however, it does not change the incidence of perioperative adverse events following LPD or the long-term prognosis of malignant tumor. The preservation of AHA during surgery can be achieved with a well-planned approach and careful dissection.

RESUMO

Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous tumour, accounting for less than 1% of malignant tumours of the head and neck region. This tumour rarely presents metastatic disease, but has a high recurrence rate. Therefore, wide surgical excision with microscopically free margins is the therapeutic gold standard. Only five cases are described in literature of this tumour arising in the parotid region, a site that presents challenges both in achieving a wide demolition and in reconstructing the resulting defect. Here we describe two cases of DFSP arising in the parotid region that were treated surgically, achieving microscopically free margins. Reconstruction of the vast skin defect was achieved by means of a supraclavicular artery island flap, with good functional and aesthetic results.

RESUMO

OBJECTIVE: To review dermatofibrosarcoma protuberans (DFSP), which is a soft tissue neoplasm of the skin that can rarely affect the genitals. MATERIAL AND METHOD: We report a case of inguinal DFSP in a 40-year-old male who presented a slow-growing mass adjacent to the spermatic cord. RESULTS: After extensive surgical resection pathological analysis confirmed the diagnosis of DFSP with resection margins affected, so reoperation with margin exeresis and inguinal orchiectomy was required. CONCLUSIONS: DFSP is rarely localized in the inguinoescrotal region and it requires wide excision and sometimes orchiectomy.

RESUMO

ABSTRACT: Endoscopic resection (ER) for non-ampullary duodenal lesions (NADLs) is technically more difficult than lesions of the stomach. However, endoscopic treatment of duodenal lesions has been increasingly performed in recent years. This study aimed to evaluate the efficacy and safety of ER for NADLs.Patients who underwent ER for NADLs between 2004 and 2019 were retrospectively reviewed. Clinical and pathologic features of the lesions including the clinical outcomes and adverse events were analyzed.The study included 80 patients with NADLs. The mean age of patients was 59.3 years (22-80 years), the mean size of the lesion was 8.8 ±â€Š7.0 mm, and the mean procedure time was 13.2 ±â€Š11.2 min. Half (40/80) of the lesions were in the duodenal bulb including the superior duodenal angle. Final histological data showed 56 adenomas (70.5%), 13 Brunner gland tumors (16.2%), and 4 pyloric gland tumors (5.0%). The final diagnoses of 5 lesions after ER showed higher-grade dysplasia compared to pre-ER biopsy findings. The en bloc resection rate was 93.8% (75/80), and the complete resection rate with clear margins was 90.0% (72/80). Micro-perforation occurred in 2 of 80 patients and was successfully treated with conservative treatment. There were no cases of delayed bleeding. The mean follow-up period was 27.0 months (2-119 months) with no cases of recurrence.ER may be an effective treatment for NADLs with favorable long-term outcomes. However, the possibility of perforation complications should always be considered during ER.

RESUMO

BACKGROUND: Surgical margin status remains a controversial factor in predicting the outcome of colorectal liver metastases (CRLM) resection. Our study aims to evaluate the effects of surgical margins on oncologic outcomes with regard to the genetic and morphological evaluation (GAME) score. METHODS: R1 resection was defined as having a less than 1 mm margin width. Patients who underwent surgery for CRLM from January 2005 to December 2018 were recruited. The patients were divided into two risk subgroups, namely, the low or medium risk (GAME 0-3) and high-risk (GAME score 4 or more) groups. The effects of margin status on overall survival (OS) and recurrence-free survival rate (RFS) were examined. RESULTS: In total, 661 patients were recruited, among which 159 (24.1%) had R1 resection. Before hepatectomy, 514 patients showed a low or medium risk (R1 resection: n = 124), while 147 patients demonstrated a high risk (R1 resection: n = 35). In the whole cohort, multivariable analysis did show that R1 resection was associated with worse RFS and OS. While further research only found that in the low or medium risk group, R1 resection was related to poor OS and RFS. Meanwhile, in the high risk group, no significant difference was found in the median OS and RFS among patients with R0 or R1 resection. CONCLUSION: The prognostic role of margin status varied according to the GAME score. Margin clearance only improved survival rates in patients with low or medium GAME score. In contrast, R1 resection demonstrated similar oncologic outcomes with R0 resection in patients with high GAME score.

RESUMO

Standard of care for high-risk cutaneous squamous cell carcinoma (cSCC) is surgical excision of the primary lesion with clear margins when possible, and additional resection of positive margins when feasible. Even with negative margins, certain high-risk factors warrant consideration of adjuvant therapy. However, which patients might benefit from adjuvant therapy is unclear, and supporting evidence is conflicting and limited to mostly small retrospective cohorts. Here, we review literature from the last decade regarding adjuvant radiation therapy and systemic therapy in high-risk cSCC, including recent and current trials and the role of immune checkpoint inhibitors. We demonstrate evidence gaps in adjuvant therapy for high-risk cSCC and the need for prognostic tools, such as gene expression profiling, to guide patient selection. More large-cohort clinical studies are needed for collecting high-quality, evidence-based data for determining which patients with high-risk cSCC may benefit from adjuvant therapy and which therapy is most appropriate for patient management.
