Melanoma AND surgery

BACKGROUND: Neoadjuvant and adjuvant immunotherapies for cancer have evolved through a series of remarkable and critical research advances; however, addressing their similarities and differences is imperative in clinical practice. Therefore, this study aimed to examine their similarities and differences from the perspective of informatics analysis. METHODS: This cross-sectional study retrospectively analyzed extensive relevant studies published between 2014 and 2023 using stringent search criteria, excluding non-peer-reviewed and non-English documents...

BACKGROUND: Tumor staging plays a pivotal role in melanoma management, where the depth of tumor invasion has been traditionally used as the cornerstone of staging. Paradoxically, the tumor diameter has not been integrated into the staging system. The aim of this study is to elucidate the clinical implications and prognostic value of tumor diameter in cutaneous melanoma, with a particular emphasis on the acral-melanoma predominant East Asian population, thus potentially enriching the clinical evaluation and treatment strategies for cutaneous melanoma...

Bone tumors of the upper limb are a common cause of bone pain and pathological fractures in both old and young populations. Surgical reconstruction and limb salvage have become valid options for these patients despite this kind of surgery being challenging due to the need for wide bone resection and the involvement of surrounding soft tissues. Computer-assisted technology helps the surgeon in pre-operative planning and in designing customized implants. The aim of this study was to investigate the surgical outcomes and complications of custom-made prostheses in oncologic reconstruction of the upper limb and if they are reliable options for patients suffering from aggressive tumors...

Melanoma case reports show variations in treatment by age and sex.

OBJECTIVE: To construct nomogram models to predict the risk factors for early death in patients with metastatic melanoma (MM). METHODS: The study covered 2138 cases from the Surveillance, Epidemiology, and End Results Program (SEER) database and all these patients were diagnosed with MM between 2010 and 2015. Logistic regression was performed to identify independent risk factors affecting early death in MM patients. These risk factors were then used to construct nomograms of all-cause early death and cancer-specific early death...

BACKGROUND: Surgeons face challenges associated with adherent cutaneous scalp malignancy. Traditional general anesthetic excision involves periosteal removal and burring of the outer table of the calvaria for deep margin clarity and tissue reconstruction. Research on this practice is limited, and graft survival in burr-treated bones is underexplored. This study aimed to assess the clinical margin accuracy for immobile scalp malignancies, identify deep-invading malignancy types, and evaluate graft survival in burr-treated calvariae...

We report the case of an 81-year-old patient with no pre-existing medical conditions who presented with a one-week history of progressive horizontal diplopia. Contrast-enhanced brain magnetic resonance imaging showed a heterogeneous sellar mass with the infiltration of the cavernous sinus and sella. Hormone levels were within normal limits. Considering an endocrine inactive pituitary adenoma, the patient underwent transsphenoidal resection. After surgery, the preoperative symptoms completely resolved. Histopathologic examination of the tumor specimen revealed melanoma...

BACKGROUND: Sinonasal Mucosal Melanoma (SNMM) is a rare but aggressive disease. Surgery with free margins, when feasible, is the treatment of choice. In the last three decades, electrochemotherapy (ECT) has emerged as a local ablative procedure, performed with the Cliniporator, for cutaneous and mucosal tumours of different histology. We present a case report of an ECT treatment performed by means of a new endoscopic electrode, on an elderly patient affected by primary SNMM. METHODS: An 88-year-old man with a diagnosis of SNMM (cT4aN0M0)-Stage IV, of the left nasal fossa presented at our institution...

OBJECTIVE: To present treatment of primary esophageal melanoma in a young patient, as well as review of modern data on this issue. MATERIAL AND METHODS: We describe the results of treatment of a patient with primary melanoma of the esophagus. PubMed, SCOPUS, and elibrary databases were used for the review. RESULTS: We present a rare case of primary esophageal melanoma and variant of radical surgical treatment. The review is devoted to historical information about this nosology, statistical data, options for diagnosis and treatment...

BACKGROUND AND OBJECTIVES: The prognosis of patients diagnosed with melanoma is highly dependent on staging, early detection, and early intervention. In this systematic review, the authors aimed to investigate the impact of surgical delay (time between diagnostic biopsy and definitive surgical excision) on melanoma-specific outcomes. MATERIAL AND METHODS: A systematic review was conducted from Embase (1974-present), MEDLINE (1946-present), Cochrane Central Register of Controlled Trials (2005-present), Scopus, and Web of Science...

<b><br>Introduction:</b> Skin cancers constitute a group of medical disorders remaining a field of interest for surgeons and dermatologists. Currently, this group is typically divided into malignant melanoma (MM) and keratinocyte cancers (KC).</br> <b><br>Aim:</b> The aim of this study is to analyze the cases of skin cancers treated in the Department of Plastic, Reconstructive, and Aesthetic Surgery in Lodz (Poland) during the COVID-19 pandemic (from 2020 to 2022) and then compare the results with the ones from the pre-pandemic period (from 2017 to 2019)...

The majority of patients who are diagnosed with cutaneous melanoma are candidates for surgical resection and thus curable from their disease. However, the risk for a recurrence is high for many patients, including those with lymph node-negative melanoma, thus necessitating additional therapies beyond surgery. With the advent of anti-programmed cell death protein 1 (PD-1)-based immunotherapies, which are vastly more effective compared to previous standard-of-care treatments in the advanced setting, the landscape of adjuvant therapy has fundamentally changed in recent years...

Cutaneous squamous cell carcinoma (cSCC) is a non-melanoma skin cancer whose lesions mostly arise on light-exposed sites. Patients with compromised immunity, Fitzpatrick I or II skin phototype, and previous burn scars or radiations are more at risk of developing it. The treatment of choice for cSCC is surgery; however nonsurgical options are generally reserved for patients who refuse a very invasive treatment or cannot tolerate a surgical procedure. We report a case of cSCC successfully treated with intralesional methotrexate...

The SWOG S1801 trial investigated the role of pembrolizumab, an anti-PD1 immune checkpoint inhibitor, in the perioperative setting of stage III or IV melanoma. This phase 2 trial compared two groups: one receiving pembrolizumab both before and after surgery (neoadjuvant-adjuvant), and another receiving it only post-surgery (adjuvant-only), with event-free survival (EFS) as the primary endpoint. Neoadjuvant strategies, involving pre-surgical drug administration, potentially offer rapid tumor control and a unique opportunity to assess tumor response...

Subungual Onycholemmal Cyst (SOC) is a rare nail abnormality with different clinical presentations which can mimic different nail malignancies, such as melanoma, SCC, or glomus tumor. It is necessary for dermatologists and dermatopathologist to be aware of this pathology to make the proper diagnosis and treatment. SOC is a rare nail abnormality which affects the dermis of the nail bed. SOC has different clinical presentations, including onychodystrophy, ridging, clubbing, thickening, pigmentation, or even normal appearance...

The recent introduction of immunotherapy and targeted therapy has substantially enriched the therapeutic landscape of metastatic melanoma. However, cerebral metastases remain unrelenting entities with atypical metabolic and genetic profiles compared to extracranial metastases, requiring combined approaches with local ablative treatment to alleviate symptoms, prevent recurrence and restore patients' biological and psychological resources for fighting malignancy. This paper aims to provide the latest scientific evidence about the rationale and timing of treatment, emphasizing the complementary roles of surgery, radiotherapy, and systemic therapy in eradicating brain metastases, with a special focus on the distinct response of intracranial and extracranial disease, which are regarded as separate molecular entities...

Melanoma treatment is leading the neo-adjuvant systemic (NAS) therapy field. It is hypothesized that having the entire tumor in situ, with all of the heterogeneous tumor antigens, allows the patient's immune system to have a broader response to the tumor in all its shapes and forms. This translates into a higher clinical efficacy. Another benefit of NAS therapy potentially includes identifying patients who have a favorable response, which could offer an opportunity for the de-escalation of the extent of surgery and the need for adjuvant radiotherapy and/or adjuvant systemic therapy, as well as tailoring the follow-up in terms of the frequency of visits and cross-sectional imaging...

Ultrasound and high-frequency ultrasound assessment of melanoma and non-melanoma skin cancer in the pre-therapeutical setting is becoming increasingly popular in the field of dermatosurgery and dermatooncology, as it can provide clinicians with relevant, "in vivo" parameters regarding tumor lateral and depth extension as well as potential locoregional spread, cancelling the need of more extensive imaging methods and avoiding a delay in diagnosis. Furthermore, preoperative sonography and color Doppler can aid in orienting the clinical diagnosis, being able in numerous situations to differentiate between benign and malignant lesions, which require a different therapeutic approach...
