INTRODUCTION: The incidence of cutaneous melanoma is increasing in Denmark and worldwide. However, the prevalence of distant metastases at the time of diagnosis has decreased to 1%. We therefore questioned the value of routine preoperative chest X-ray (CXR) for staging asymptomatic melanoma patients and hypothesised that routine CXR is not justified. METHODS: A retrospective study was conducted on patients undergoing wide local excision and sentinel lymph node biopsy for cutaneous melanoma in the period from 2010 to 2014...

BRAF mutations occur commonly in metastatic melanomas and inhibition of mutant BRAF and the downstream kinase MEK results in rapid tumor regression and prolonged survival in patients. Combined therapy with BRAF and MEK inhibition improves response rate, progression free survival and overall survival compared with single agent BRAF inhibition, and reduces the skin toxicity that is seen with BRAF inhibitor monotherapy. However, this combination is associated with an increase in other toxicities, particularly drug-related pyrexia, which affects approximately 50% of patients treated with dabrafenib and trametinib (CombiDT)...

OBJECTIVE The use of Gamma Knife radiosurgery (GKRS) as monotherapy in the treatment of uveal melanoma (UM) allows clinicians to achieve high local tumor control with low recurrence but does not prevent secondary enucleation due to glaucoma in cases of large tumors. The authors analyzed indications for tumor endoresection (ER), the time interval between irradiation and surgery, and the features and results of performing ER for UM after GKRS. METHODS Thirty-seven patients between 28 and 78 years of age (16 male and 11 female patients) with UM underwent GKRS with a dose of 70 to 80 Gy that was applied to the center of the tumor with complete immobilization of the eye during the procedure...

A 68-year-old woman presented with symptoms of bleeding per vaginum. On examination, a growth was seen in the cervix, clinically considered to be squamous cell carcinoma. The growth was confined to the cervix and did not involve the parametria. However, on biopsy it was diagnosed as malignant melanoma. She underwent surgery elsewhere and was advised chemotherapy as these tumours are aggressive; however, she refused chemotherapy. She has been on regular follow-up and has an ongoing survival and disease-free period of more than 5 years...

Metastectomy remains the only treatment in malignant melanoma to offer complete pathologic response within a few days of in-hospital stay. It has been historically associated with the highest survival rates in the literature reported for patients of this stage. However, only a minority of patients are amenable to curative resection of distant metastatic disease. This patient group exhibit slow growing oligometastases as indicated by: a. Long disease free interval after treatment of their primary tumours and b...

INTRODUCTION: Incidence of cutaneous and uveal forms of malignant melanoma (MM) has increased significantly in the population in the last years. Biological behavior of both these forms of MM is different and is associated with the development of liver metastases. The prognosis of patients with MM liver metastases is generally poor. The authors seek to consider the sense and the possibilities of surgical treatment of MM liver metastases. METHOD: Seven patients with liver metastases of MM were operated on in the Hepatobiliary Center of the Department of Surgery, University Hospital in Pilsen during the last ten years...

INTRODUCTION: Phosphodiesterase 5 (PDE5) inhibitors (PDE5i) have been used clinically for the treatment of erectile dysfunction, acting on the nitric oxide/cyclic guanosine monophosphate (NO/cGMP) signaling pathway. Simultaneously, researchers have elucidated the roles that this pathway plays in the regulation of cell proliferation, tumor development, and progression. As a result, our knowledge of PDE5i and cancer biology has expanded and provides an integration that holds great promise for some, but concern for others...

BACKGROUND: Early detection of melanoma is vital for treatment outcome and survival. Short-term sequential digital dermoscopic monitoring (ST-SDDM) involves the capture and assessment of dermoscopic images of one or more atypical melanocytic lesions (AMLs), at baseline and after four months, in order to detect early morphologic changes. Electrical impedance spectroscopy (EIS) is a diagnostic tool with high sensitivity for the detection of malignant melanocytic lesions. OBJECTIVES: The aim of this study was to assess whether EIS, in addition to ST-SDDM, could improve the selection of AMLs requiring surgery...

INTRODUCTION: Sentinel lymph node (SLN) biopsy is widely accepted as an important part of staging cutaneous malignant melanoma. Hybrid single photon emission computed tomography and computed tomography (SPECT/CT) may identify additional SLN and provide important information to the surgeon performing SLN biopsy. We report our experience at a major referral centre for melanoma surgery. METHODS: Retrospective case series of pre-operative sentinel node lymphoscintigraphy for primary melanoma over a consecutive 12-month period...

Bulky naevocytoma of the perineum is a very rare variant of giant congenital melanocytic naevus (GCMN). It presents as a bulky naevocytic tumour in the perineal region with characteristic histological findings, such as extensive areas with a neural appearance called 'lames foliacees', formation of a pseudofollicular structure and extension of naevus cells between collagen bundles in a row called 'Indian-file' pattern. We report a case of late-onset bulky naevocytoma of the perineum in a 13-year-old girl. The patient presented with two bulky, pedunculated, heavily pigmented masses in the vulvar area that developed in a pre-existing GCMN lesion, which began around puberty and caused severe gait disturbance...

Basal cell carcinoma is the most common non-melanoma skin cancer, and its incidence continues to raise. Although surgery can be considered the mainstay of therapy, new current pharmacological options are available and focus on tumor eradication, maximizing cosmetic results, and functional capacity. Several studies have recently reported on safety and efficacy of topical ingenol mebutate gel, a derivative of the plant Euphorbia Peplus, used to treat actinic keratosis and superficial basal cell carcinoma. In our knowledge, we report for the first time the dermoscopic evaluation of outcome and monitoring of superficial pigmented and non-pigmented basal cell carcinomas in four patients treated by this novel non-ablative agent...

BACKGROUND: The treatment of oncological diseases is based on the combination of surgery, representing the key step for the removal of the tumor tissue, radiotherapy, chemotherapy, and hormone therapy. However, the surgery is often accompanied by issue of determining the boundaries of the tumor. Prior the operation, the surgeon has information on preoperative findings, which indicate the location and extent of the tumor, but does not specify a clear boundary between the tumor and healthy tissue...

Anorectal malignant melanoma is a very rare but lethal disease. Patients with anorectal malignant melanoma commonly complain for changes in bowel habits and rectal bleeding. Therefore, anorectal malignant melanoma is often misdiagnosed as hemorrhoids, polyp or rectal cancer. Surgery is the mainstay of treatment for patients with anorectal malignant melanoma. However, whether abdominoperineal resection or wide local excision is the most appropriate surgical approach is still a controversial issue. Recently, with the great development of laparoscopic techniques, more and more operations can be performed by laparoscopic techniques...
