Background: Since the early 1990s, the minimally invasive image-guided therapies used in interventional oncology to treat hepatocellular carcinoma have continued to evolve. Additionally, the range of applications has been expanded to the treatment of hepatic metastases from colorectal cancer, neuroendocrine tumors, cholangiocarcinoma, breast cancer, melanoma, and sarcoma. Methods: We searched the literature to identify publications from 1990 to the present on various image-guided intraarterial therapies and their efficacy, as well as their role in the management of primary and secondary liver malignancies...

BACKGROUND AND OBJECTIVES: Variability in melanoma management has prompted concerns about equitable and timely treatment. We investigated patterns of melanoma diagnosis and treatment using population-level data. METHODS: Patients with invasive cutaneous melanoma were identified retrospectively from the Ontario Cancer Registry (2003-2012) and deterministically linked with administrative databases to identify incidence, disease characteristics, geographic origin, and multimodal treatment within a year of diagnosis...

A 69-year-old male patient with a history of melanoma and prostate cancer was found to have a 2.6 cm PET-avid, slowly enlarging, left upper lobe lung nodule that was suspicious for either metastasis or primary lung cancer. Due to the deep location of the nodule, a wedge resection was not recommended. A diagnostic and therapeutic uniportal video-assisted thoracoscopic surgery (U-VATS) left upper lobe trisegmentectomy was performed uneventfully. Final pathology confirmed the presence of metastasis from prostate cancer without lymph node involvement...

REVIEW
Kristian M Hargadon
Melanoma is a highly aggressive form of skin cancer that frequently metastasizes to vital organs, where it is often difficult to treat with traditional therapies such as surgery and radiation. In such cases of metastatic disease, immunotherapy has emerged in recent years as an exciting treatment option for melanoma patients. Despite unprecedented successes with immune therapy in the clinic, many patients still experience disease relapse, and others fail to respond at all, thus highlighting the need to better understand factors that influence the efficacy of antitumor immune responses...

Murine orthotopic cancer models often require surgery, potentially causing pain or distress. However, analgesics are often withheld because they may alter tumour development. Two orthotopically implanted cancers were investigated in mice pre-treated with meloxicam (10 mg/kg), buprenorphine (0.2 mg/kg) or saline (1 ml/kg). Tumours were imaged and welfare was assessed using body weight, behaviour and nociceptive responses. In study 1, BALB/c mice were inoculated with 4T1 mammary carcinoma or saline during surgery or anaesthesia...

It has recently been shown that cancer treatments such as radiation and hyperthermia, which have conventionally been viewed to have modest immune based anti-cancer effects, may, if used appropriately stimulate a significant and potentially effective local and systemic anti-cancer immune effect (abscopal effect) and improved prognosis. Using eight spontaneous canine cancers (2 oral melanoma, 3 oral amelioblastomas and 1 carcinomas), we have shown that hypofractionated radiation (6 x 6 Gy) and/or magnetic nanoparticle hyperthermia (2 X 43°C / 45 minutes) and/or an immunogenic virus-like nanoparticle (VLP, 2 x 200 μg) are capable of delivering a highly effective cancer treatment that includes an immunogenic component...

Studies on melanoma brain metastases (MBM) with regard to mutational status are lacking. We investigated the outcomes of MBM in molecularly characterized patients for BRAF and NRAS mutations receiving conventional treatment. We investigated associations between outcomes [competing risk of local and distant brain failure (LF, DF) and overall survival (OS)] and clinical/pathological features of patients with known mutation status following initial treatment of MBM. Competing risk analysis was performed using the methods of Fine and Gray...

OBJECTIVE: Malignant melanoma accounts for nearly 75% of all skin cancer deaths, and the incidence is on the rise in the United States. External ear melanoma (EEM) is rare, and there is little long-term data regarding the clinical behavior of this melanoma site. This study analyzes the demographic, clinicopathologic, and survival characteristics of EEM. METHODS: The SEER database was queried for EEM cases from 1973 to 2012 (8,982 cases). Data analyzed included patient demographics, incidence trends, and survival outcomes...

BACKGROUND: Primary melanoma of the vagina (PMV) is a rare entity. The prognosis of women with PMV is poor and there is no standardized therapy for this type of malignancy. We present the case of a 72-year-old woman with PMV (cT2, pN0, M0). CASE REPORT: Imaging studies showed no evidence of regional or distant metastases. Molecular analysis demonstrated wild-type B-Raf proto-oncogene, serine/threonine kinase (BRAF). Staging laparoscopy with pelvic lymphadenectomy and subsequent radiotherapy with 60 Gy delivered as pelvic teletherapy and vaginal brachytherapy was applied...

Squamous cell carcinoma (SCC) of the skin is a keratinocyte malignancy characterized by tumors presenting on sun exposed areas with surgery being the mainstay treatment. Despite advances in targeted therapy in other skin cancers, such as basal cell carcinoma and melanoma, there have been no such advances in the treatment of SCC. This is partly due to an incomplete knowledge of the pathogenesis of SCC. We have recently identified PKK, a protein kinase C-associated kinase, as a potential tumor suppressor in SCC...

Among childhood cancer survivors (CCSs), non-melanoma skin cancer (NMSC) is the most common type of second malignancy. Morbidity related to the development of NMSC in this group of patients may be sometimes unpredictable and difficult to manage. We present the case of a 49-year-old female who was a CCS and developed giant superficial basal cell carcinomas (sBCCs) over the previously irradiated field of the scalp. BCC involved the atrophic skin overlying the catheter of the peritoneal cerebral shunt that was set there for the management of hydrocephalus...

Talimogene laherparepvec is a genetically modified herpes simplex virus-1-based oncolytic immunotherapy for the local treatment of unresectable cutaneous, subcutaneous, and nodal tumors in patients with melanoma recurrence following surgery. We aim to describe the safety of talimogene laherparepvec. Intralesional talimogene laherparepvec was administered at less than or equal to 4 ml×10 PFU/ml at protocol day 1, then less than or equal to 4 ml×10 PFU/ml 21 days later, and then every 14 days. Treatment continued until complete response, absence of injectable tumors, progressive disease, intolerance, or US Food and Drug Administration approval...

Melanoma demonstrates considerable biological heterogeneity and is associated with several routes of dissemination including lymphatic and hematogenous. Locoregional control via surgery may improve outcomes for patients with limited lymphatic metastases. Once stage IV disease is diagnosed, clinical outcomes are determined by molecular and/or immunologic factors and identification of tumor/microenvironmental features correlating with distant metastases is critical for future prognostic stratification.

We report 85 lesions of non-melanoma skin cancer in 58 patients, representing 9% of the minor surgical workload of a single general practitioner. Cases were studied in order to describe pathology, management and outcomes. Eighteen percent of lesions were referred, mainly because of central facial site and larger size. Of the lesions treated in the surgery, all but four were treated surgically. Quantitative margins of lateral and deep excision were reported for 50% and 30% of specimens respectively. Lateral histological margins of clearance were narrower for head and neck lesions...

BACKGROUND: BRCA1-Associated-Protein 1 (BAP1) is a dynamic tumor suppressor which, when mutated, has been associated with an increased risk of uveal melanoma, cutaneous melanoma, mesothelioma, and several other cancers. Germline BAP1 mutations have been extensively studied, where they have been found to cause hereditary cancer susceptibility. However, their sporadic counterparts, tumors that display a loss of BAP1 expression due to somatically arising mutations in the BAP1 gene, remain a poorly described entity...
