ABSTRACT

Introdução: O reparo tecidual e a cicatrização de feridas cutâneas são processos complexos que envolvem uma série de eventos dinâmicos, incluindo coagulação, inflamação, formação de tecido de granulação, contração da ferida e remodelação tecidual. A necessidade de cuidar de pacientes com dificuldades na cicatrização de feridas é um desafio crescente e requer estratégias inovadoras. Uma abordagem que se destaca no tratamento dessas lesões é a laserterapia de baixa potência. Este estudo tem como objetivo demonstrar a aplicabilidade e os resultados de um protocolo de laserterapia de baixa potência no manejo da cicatrização de feridas cutâneas. Métodos: Trata-se de estudo retrospectivo de revisão de casos relatando o uso de laser no tratamento de feridas cutâneas em um centro único. Resultados: Avaliamos os resultados do uso de laserterapia de baixa potência e relatamos cinco casos de pacientes com feridas cutânea que não apresentaram melhora com o tratamento convencional. As lesões eram localizadas em sítios diversos, com lesão no tronco, membro superior e membro inferior. Os cinco casos apresentaram uma boa resposta com a terapia a laser, evoluindo com a cicatrização das feridas em um curto período de tempo, com período médio de cicatrização de 48 dias. Conclusão: Conclui-se que a laserterapia de baixa potência quando aplicada sobre feridas cutâneas sugere uma ação benéfica, promissora e tem um potencial para aumentar as opções terapêuticas disponíveis para o cirurgião, porém, como relatamos um número de cinco casos, há necessidade de mais estudos para verificar a eficiência do laser em feridas.


Introduction: Tissue repair and skin wound healing are complex processes that involve a series of dynamic events, including coagulation, inflammation, granulation tissue formation, wound contraction and tissue remodeling. The need to care for patients with difficulties in wound healing is a growing challenge and requires innovative strategies. One approach that stands out in the treatment of these injuries is low-power laser therapy. This study aims to demonstrate the applicability and results of a low-power laser therapy protocol in the management of skin wound healing. Methods: This is a retrospective case review study reporting the use of laser in the treatment of skin wounds in a single center. Results: We evaluated the results of the implementation of this low-power laser therapy protocol and reported five cases of patients with skin wounds that did not improve with conventional treatment. The lesions were located in different places, with lesions on the trunk, upper limb and lower limb. The five cases showed a good response to laser therapy, evolving with wound healing in a short period of time, with an average healing time of 48 days. Conclusion: It is concluded that low power laser therapy when applied to skin wounds suggests a beneficial, promising action and has the potential to increase the therapeutic options available to the surgeon, however as we report a number of five cases, further studies are needed for check laser efficiency on wounds.

ABSTRACT

Introdução: A reconstrução do couro cabeludo após a ressecção oncológica continua sendo um desafio para o cirurgião, especialmente considerando a incidência crescente de câncer de pele entre pacientes idosos. A matriz dérmica (MD) é um grupo heterogêneo de materiais de cobertura de feridas que auxiliam no fechamento da ferida e substituem algumas das funções da pele, temporária ou permanentemente. Pacientes com maior risco cirúrgico podem se beneficiar do uso de MD, que ajuda a gerar uma nova derme, oferecendo grandes melhorias na cobertura de defeitos complexos e extensos. Métodos: É um trabalho retrospectivo com análise de prontuário e relato de dois casos de pacientes do A.C.Camargo Cancer Center-SP, Brasil. Resultados: Relatamos dois casos de defeitos complexos e extensos de couro cabeludo em um centro único usando MD associada a enxerto cutâneo e terapia de pressão negativa (TPN) na cirurgia reconstrutiva após ressecção de neoplasia maligna da pele com resultados funcionais e estético satisfatório. Conclusões: As lesões extensas do couro cabeludo são um desafio na prática clínica e um tratamento multidisciplinar é fundamental. Os resultados obtidos indicam que a MD associada com a enxertia de pele parcial e com a TPN tem enorme potencial para aumentar as opções terapêuticas disponíveis para o cirurgião e possivelmente beneficiando os pacientes, especialmente aqueles que não têm condições clínicas para uma cirurgia extensa de cobertura com retalho microcirúrgico.


Introduction: Scalp reconstruction after cancer resection remains a challenge for surgeons, especially considering the increasing incidence of skin cancer among elderly patients. Dermal matrix (DM) is a heterogeneous group of wound covering materials that aid in wound closure and replace some of the skins functions, either temporarily or permanently. Patients at higher surgical risk can benefit from the use of DM, which help to generate a new dermis, offering great improvements in coverage of complex and extensive defects Methods: It is a retrospective study with analysis of medical records and report of two cases of patients at the A.C.Camargo Cancer Center-SP, Brazil. Results: We report two cases of complex and extensive scalp defects at a single center using DM associated with skin grafting and negative pressure therapy (NPT) in reconstructive surgery after resection of malignant skin neoplasm with satisfactory functional and esthetic results. Conclusions: Extensive lesions of the scalp are a challenge in clinical practice and a multidisciplinary treatment is essential. The results obtained indicate that DM associated with partial skin grafting and NPT have enormous potential to increase the therapeutic options available to the surgeon and possibly benefit patients, especially those who do not have the clinical conditions for extensive coverage surgery with microsurgical flap.

ABSTRACT

Abstract Background: Basal cell and squamous cell carcinomas (BCC and SCC) are the most common types of cancer worldwide. Intraoperative assessment of surgical margins by frozen section has been widely used to ensure disease-free margins. The intraoperative ‟en face" freezing technique evaluates all peripheral and deep margins. Objective: To report the results of the ‟en face" freezing technique in relation to tumor recurrence and agreement with paraffin-embedded tissue examination. Methods: Retrospective analysis of patients undergoing surgical excision of BCC and SCC at the A. C. Camargo Cancer Center, Brazil. Results: This study included 542 skin carcinomas, which were excised from 397 patients. A total of 201 male patients (50.6%), and 196 female patients (49.4%) were assessed, whose mean age was 64 years. The tumors were mostly located on the head and neck region (87.8%). BCC corresponded to 79.7% of the cases. The mean follow-up was 38 months. Tumor relapse occurred in 0.86% of the primary tumors and 3.7% of recurrent tumors. The result of the intraoperative ‟en face" frozen section evaluation was in agreement with the final result of the anatomopathological examination (paraffin test) in 98% of the lesions. Study limitations: Not having a minimum follow-up time of 5 years for all patients. Conclusion: The ‟en face" freezing technique shows low tumor relapse, being reliable and safe to guarantee negative surgical margins of the tumor.

ABSTRACT

Abstract Background: The mitotic index is no longer used to classify T1 melanoma patients into T1a and T1b, so it should not be used to indicate sentinel node biopsy in these patients. Objectives: To evaluate patients with T1 melanoma who underwent sentinel lymph node biopsy and to compare those who were classified as T1a with those classified T1b, according to the 7th and 8th Edition of the melanoma staging system, regarding a positive biopsy result. The authors also aimed to assess whether there is any difference in the results in both staging systems. Material and methods: This was a retrospective analysis of 1213 patients who underwent sentinel lymph node biopsy for melanoma, from 2000 to 2015, in a single institution. Results: Of 399 patients with thin melanomas, 27 (6.7%) presented positive sentinel lymph nodes; there was no difference in positivity for sentinel node biopsy when comparing T1a vs. T1b in both staging systems. Furthermore, the clinical results were also similar between the two groups. However, in the complete cohort analysis, the mitotic index was associated with positivity for sentinel lymph node biopsy (p < 0.0001), positivity for non-sentinel lymph node (p < 0.0001), recurrence-free survival (p < 0.0001), and specific melanoma survival (p = 0.023). Study limitation: Unicentric study. Conclusion: The mitotic index was shown to be a very important prognostic factor in the present study, but it was not observed in patients classified as T1. The mitotic index should no longer be used as the only reason to refer sentinel lymph node biopsy in patients with thin melanoma.

ABSTRACT

Abstract: Diphencyprone has been reported as a local immunotherapy for cutaneous melanoma metastases. We aim to report cases of melanoma patients treated with diphencyprone in a single Brazilian institution and highlight their outcomes. Since 2012, we have treated 16 melanoma patients with cutaneous metastases with topical diphencyprone. To date, we have had 37.5% of complete response, 25% of partial responses, and 31.25% patients without any response. Treatment was well tolerated and local toxicity was easily controlled. We believe topical diphencyprone is a feasible treatment that can be another option for treating melanoma patients, especially in cases of in-transit or extensive disease.

ABSTRACT

Abstract The last Brazilian guidelines on melanoma were published in 2002. Development in diagnosis and treatment made updating necessary. The coordinators elaborated ten clinical questions, based on PICO system. A Medline search, according to specific MeSH terms for each of the 10 questions was performed and articles selected were classified from A to D according to level of scientific evidence. Based on the results, recommendations were defined and classified according to scientific strength. The present Guidelines were divided in two parts for editorial and publication reasons. In this second part, the following clinical questions were answered: 1) which patients with primary cutaneous melanoma benefit from sentinel lymph node biopsy? 2) Follow-up with body mapping is indicated for which patients? 3) Is preventive excision of acral nevi beneficious to patients? 4) Is preventive excision of giant congenital nevi beneficious to patients? 5) How should stages 0 and I primary cutaneous melanoma patients be followed?.

ABSTRACT

Abstract

Vemurafenib is a selective inhibitor of V600E-mutant BRAF protein used to treat metastatic and unresectable melanoma. Clinical trials have shown increased overall survival and progression-free survival in patients treated with Vemurafenib. However, cutaneous adverse events are common during treatment. We report fi ve cases of metastatic melanoma with BRAF V600E positivity, treated with Vemurafenib and its cutaneous adverse events. Dermatologists and oncologists need to be aware of possible skin changes caused by this medication, which is increasingly employed in melanoma treatment. Monitoring of patients during therapy is important for early treatment of adverse cutaneous cutaneous adverse events, improvement in quality of life and adherence to treatment.

ABSTRACT

The diagnosis of lymphedema can be obtained objectively by measurement methods, and also by subjective methods, based on the patient's complaint. OBJECTIVE: To evaluate inter-rater reliability of objective and subjective criteria used for diagnosis of lymphedema and to propose a lymphedema cut-off for differences in volume between affected and control limbs. METHODS: We studied 84 patients who had undergone lymphadenectomy for treatment of cutaneous melanoma. Physical measures were obtained by manual perimetry (MP). The subjective criteria analyzed were clinical diagnosis of lymphedema in patients' medical records and self-report of feelings of heaviness and/or increase in volume in the affected limb. RESULTS: For upper limbs, the subjective criteria clinical observation (k 0.754, P<0.001) and heaviness and swelling (k 0.689, P<0.001) both exhibited strong agreement with MP results and there was moderate agreement between MP results and swelling (k 0.483 P<0.001), heaviness (k 0.576, P<0.001) and heaviness or swelling (k 0.412, P=0.001). For lower limbs there was moderate agreement between MP results and clinical observation (k 0.423, P=0.003) and regular agreement between MP and self-report of swelling (k 0.383, P=0.003). Cut-off values for diagnosing lymphedema were defined as a 9.7% difference between an affected upper limb and control upper limb and a 5.7% difference between lower limbs. CONCLUSION: Manual perimetry, medical criteria, and self-report of heaviness and/or swelling exhibited better agreement for upper limbs than for lower limbs for diagnosis of lymphedema...


O diagnóstico de linfedema pode ser obtido tanto de forma objetiva, por métodos de mensuração, quanto por métodos subjetivos, através da queixa do paciente. OBJETIVO: Examinar a confiabilidade entre critérios objetivos e subjetivos utilizados para o diagnóstico de linfedema e propor um ponto de corte para linfedema de membros superiores e inferiores. MÉTODOS: Foram estudados 84 pacientes submetidos à linfonodectomias para o tratamento do melanoma cutâneo. As mensurações dos membros foram feitas utilizando a perimetria manual. Os critérios subjetivos foram obtidos através do diagnóstico de linfedema nos prontuários dos pacientes (observação clínica) e de auto-relato de sensação de peso e/ou aumento de volume no membro afetado. RESULTADOS: Nos membros superiores, houve uma forte correlação entre a perimetria manual e cada um dos critérios subjetivos: observação clínica (k 0,754, P<0,001) e sensação de peso eaumento de volume (k 0,689, P<0,001); concordância moderada no aumento de volume (k 0,483, P<0,001), peso (k 0,576, P<0,001) e sensação de peso ou aumento de volume (k 0,412, P=0,001). Nos membros inferiores, houve concordância moderada entre a perimetria e observação clínica (k 0,423, P=0,003) e regular no aumento de volume (k 0,383, P=0,003). O ponto de corte para definir linfedema foi uma diferença de 9,7% entre o membro afetado e o controle, e 5,7% de diferença para membros inferiores. CONCLUSÃO: Perimetria, observação clínica e auto-relato de sensação de peso e/ou aumento de volume, apresentaram melhor concordância para membros superiores que para inferiores no diagnóstico de linfedema...

ABSTRACT

Introdução: A microscopia confocal in vivo é método diagnóstico não invasivo auxiliar no diagnóstico de lesões hiperpigmentadas em cicatrizes. Objetivos: Avaliar através do exame de microscopia confocal a hiperpigmentação em cicatrizes de lesões melanocíticas benignas e malignas. Métodos: Avaliamos imagens clínicas, dermatoscópicas e de microscopia confocal de 14 pacientes com hiperpigmentação em cicatrizes de melanomas adequadamente tratados e nevos melanocíticos excisados. Resultados: Dos oito pacientes com hiperpigmentação em cicatrizes de melanomas, quatro não apresentaram estruturas suspeitas ao exame de microscopia confocal, e quatro apresentaram estruturas suspeitas. Entre os seis pacientes com hiperpigmentação em área de cicatriz de nevo melanocítico excisado, três apresentavam estruturas atípicas, como células dendríticas e papilas não demarcadas. Os pacientes com estruturas suspeitas realizaram exame histológico, e em um caso de hiperpigmentação em cicatriz de lentigo maligno foi evidenciado recidiva. Conclusões: O exame permitiu evitar a biópsia para confirmação diagnóstica em seis dos 14 pacientes avaliados. O achado de células com padrão dendrítico ou pagetoide no exame de microscopia confocal é um desafio diagnóstico, pois pode representar melanócitos ou células de Langerhans na camada espinhosa. Portanto, lesões que apresentam tais estruturas devem ser removidas para exame histológico e diagnóstico diferencial.


Introduction: In vivo confocal microscopy is an auxiliary non-invasive diagnostic method used in the diagnosis of hyperpigmented lesions in scars. Objectives: To evaluate hyperpigmentation in the scars of benign and malignant melanocytic lesions through confocal microscopy examination. Methods: Clinical, dermoscopic, and confocal microscopy images of fourteen patients with hyperpigmentation in adequately treated melanoma scars and in excised melanocytic nevi, were evaluated. Results: Among the eight patients with hyperpigmentation in melanoma scars, four showed no suspicious structures after confocal microscopy examination and four showed suspicious structures. Among the six patients with hyperpigmentation in areas where melanocytic nevi had been excised, three had atypical structures, such as dendritic cells and non demarcated papillae. Patients with suspicious structures underwent histological examination, with one case of hyperpigmentation in a lentigo maligna scar evidencing recurrence. Conclusions: The examination method allowed for the avoiding of biopsy in confirming the diagnosis in six of the fourteen patients. The finding of cells with dendritic or pagetoid pattern in the confocal microscopy examination means a diagnostic challenge, for it can indicate melanocytes or Langerhans cells in the spinous layer. Therefore, lesions that have such structures must be removed for histology and differential diagnosis.

ABSTRACT

OBJECTIVE: Isolated limb perfusion combined with melphalan is an accepted treatment for obtaining locoregional control in advanced melanoma of the extremities and other malignant neoplasias restricted to the limb. This study aims to examine the factors associated with toxicity caused by the regional method. We considered the technical aspects of severe complications associated with the procedure in an attempt to diminish the patient morbidity that occurs during the learning curve. METHODS: We conducted a retrospective analysis of the records of patients who underwent perfusion at the AC Camargo Hospital in São Paulo, Brazil between January 2000 and January 2009. The Wieberdink scale was applied to classify local toxicity and its relation to clinical and laboratory variables. RESULTS: Fifty-eight perfusions were performed in 55 patients. Most patients (86.2%) presented a toxicity level between I and III. Grade V toxicity was seen in five cases (8.6%), four of which occurred in the first 2 years. Creatine phosphokinase, an important predictive factor for toxicity, had an average value of 231.8 for toxicity grades I-III and 1286.2 for toxicity grades IV-V (p = 0.001). There was a relationship between the melphalan dose and toxicity, which was 77 mg (25 to 130 mg) for toxicity grades I-II and 93.5 mg (45 to 120 mg) for toxicity grades IV-V (p = 0.0204). CONCLUSION: It is possible to prevent the toxicity associated with melphalan by adjusting the dose according to the patient's body weight (especially for women and obese patients) and the creatine phosphokinase values in the postoperative period.

ABSTRACT

OBJECTIVE: Analyze if patients who had radical lymphadenectomies as a treatment for cutaneous melanoma underwent physiotherapy, observing whether or not lymphedema developed, in addition to observing what techniques were used and whether orientation as to the prevention of lymphedema was received. MATERIALS AND METHODS: We evaluated 84 patients submitted to axillary, inguinal and ilioinguinal lymphadenectomies as a treatment for cutaneous melanoma. The patients enrolled underwent an evaluation consisting of measurement of limb volume by manual perimetry and questions. RESULTS: The majority of patients with lymphedema (78.8 percent) underwent postoperative physical therapy. Somewhat troubling is the fact that only 12 individuals with lymphedema remain under treatment (36.4 percent), while the remaining 21 (63.6 percent) did not undergo physical therapy. The start of physical therapy after a 6-month postoperative period (p = 0.007) and after the onset of lymphedema (p = 0.005), performing manual lymph drainage (p = 0.008) and orientation on elastic sleeve or cuff (p < 0.001) showed statistically significant differences when compared to lymphedema and non-lymphedema patient groups. CONCLUSION: Most patients who had lymphedema underwent physiotherapy treatment. In place of a complete regimen of complex decongestive physical therapy, most patients inadequately substituted their physical therapy with isolated techniques. Most patients received orientation on how to prevent lymphedema.

ABSTRACT

Introdução: Um dos maiores desafios em dermatoscopia é diferenciar melanomas precoces e nevos benignos duvidosos. Lesões melanocíticas suspeitas algumas vezes possuem características dermatoscópicas similares às dos melanomas, induzindo a excisões excessivas. Objetivo: Desenvolver um modelo dermatoscópico que auxilia na diferenciação entre o nevo duvidoso e o melanoma precoce. Métodos: Um total de 129 imagens confirmadas histopatologicamente foram analisadas, seguindo-se uma comparação entre nevos duvidosos e melanomas precoces. Resultados: O modelo final baseou-se em três características dermatoscópicas: estrias radiadas, tonalidade azulada e estrututras vasculares. Na ausência das três características, havia grande probabilidade da lesão tratar-se de um nevo; se uma das características dermatoscópicas estivesse presente, a lesão poderia ser classificada como nevo ou melanoma; se duas das características estivessem presentes haveria maior probabilidade de diagnóstico de melanoma; se as três características estivessem presentes, então se tratava de um melanoma.


Introduction: One of the most challenging dermoscopic situations is to distinguish between early melanomas and doubtful benign nevi. At times, suspicious melanocytic lesions have dermoscopic features similar to melanomas, thus leading to excessive excisions of lesions. Objective: To develop a dermoscopic model that helps to differentiate the doubtful nevus from the early melanoma. Material and methods: A total of 219 histopathologically confirmed dermoscopic images were analyzed and a comparison between doubtful nevi and early melanomas was then performed. Results: The final model was based on three dermoscopic features: radial streaming, blue hue and vascular structures. If all three features were absent, it was most likely a nevus; if one dermoscopic feature was present, it could be a nevus or melanoma; if two features were present, there was a greater probability of melanoma diagnosis; if three features were present, it was melanoma. Conclusion: This model could help for the surgical decision.

ABSTRACT

O prognóstico do melanoma cutâneo depende principalmente da sua espessura, sendo a detecção precoce de melanomas iniciais extremamente importante para a maior sobrevida dos pacientes. Com a utilização do exame dermatoscópico, pode-se alcançar acurácia de aproximadamente 90%. Alterações em lesões pigmentadas durante a gestação podem ocorrer, porém a dificuldade é saber se são benignas ou se correspondem a melanoma. O recurso diagnóstico da dermatoscopia permite aumentar a margem de acerto no diagnóstico e na detecção do melanoma nos estádios mais iniciais, melhorando o prognóstico e consequentemente a sobrevida do paciente.

ABSTRACT

Atypical Mole Syndrome is the most important phenotypic risk factor for developing cutaneous melanoma, a malignancy that accounts for about 80 percent of deaths from skin cancer. Because the diagnosis of melanoma at an early stage is of great prognostic relevance, the identification of Atypical Mole Syndrome carriers is essential, as well as the creation of recommended preventative measures that must be taken by these patients.

ABSTRACT

Objectives: The objective of this study is to compare the joint range of motion (ROM) reduction between the submitted limb to lymphadenectomy and contralateral and to evaluate if ROM restriction is also connected with lymphedema. Materials and Methods: Evaluated were 84 patients submitted to axillary lymphadenectomy (n=40), inguinal (21) or ilioinguinal (23) for the treatment of cutaneous melanoma, operated between 1990 and 2008. Individuals excluded were those with amputation of a limb or bilateral dissection that would make perimetry and goniometry comparison impossible. The invited patients were submitted to goniometric evaluation of the shoulder or hip and measurement of the upper or lower limbs through manual perimetry. Results: The difference of 4.2 degrees between the averages of ROM flexion (p=0.005) of the shoulder of the affected side in relation to the control, and 5.2 degrees in abduction (p=0.002) were sufficient to be statistically significant, with the exception of 3 degrees of external rotation (p=0.135). The differences between the means of hip ROM were also significant, varying 8.5 degrees in flexion (p <0.001) and 2.2 degrees in abduction (p=0.011). The ROM of the shoulder or hip of the affected side did not present differences between the 33 patients with lymphedema in relation to the 51 patients without lymphedema: shoulder with flexion (p=0.148), abduction (p=0.577) and external rotation (p=0.866); hip with flexion (p = 0.665) and abduction (p=0.795). Conclusion: In spite of individuals with lymphadenectomy show restriction of joint ROM in flexion and abduction of the shoulder and hip in the late postoperative period, there was no association between joint ROM, of the shoulder on both the hip and the presence of lymphedema.
