REVIEW
Antonis Valachis, Gustav J Ullenhag
The incidence of malignant melanoma is growing rapidly. Approximately half of the cases are BRAF mutated, making treatment with kinase inhibitors a (MEK and BRAF inhibitors) preferred choice in the advanced setting. The vast majority of these patients will benefit from the treatment. It is therefore of vital importance that the BRAF analysis is reliable and reflects the true nature of the tumour. Intraindividual tumour BRAF heterogeneity may exist, and changes of BRAF status over time might occur. We reviewed the literature by searching the PubMed database and 630 potentially relevant studies were identified...

The sentinel lymph node (SLN) biopsy is probably the most well known radioguided technique in surgical oncology. Today SLN biopsy reduces the morbidity associated with lymphadenectomy and increases the identification rate of occult lymphatic metastases by offering the pathologist the lymph nodes with the highest probability of containing metastatic cells. These advantages may result in a change in clinical clinical management both in melanoma and breast cancer patients. The SLN evaluation by pathology currently implies tumour burden stratification for further prognostic information...

Mycobacterium bovis bacille Calmette-Guérin (BCG) is listed as an intralesional (IL) therapeutic option for inoperable stage III in-transit melanoma in the National Comprehensive Cancer Network Guidelines. Although the mechanism is unknown, others have reported up to 50% regression of injected lesions, and 17% regression of uninjected lesions in immunocompetent patients after direct injection of BCG into metastatic melanoma lesions in the skin. BCG and other mycobacteria express ligands capable of stimulating the γ9δ2 T cells...

Advances in cancer immunotherapy have offered new hope for patients with metastatic disease. This unfolding success story has been exemplified by a growing arsenal of novel immunotherapeutics, including blocking antibodies targeting immune checkpoint pathways, cancer vaccines, and adoptive cell therapy (ACT). Nonetheless, clinical benefit remains highly variable and patient-specific, in part, because all immunotherapeutic regimens vitally hinge on the capacity of endogenous and/or adoptively transferred T-effector (Teff) cells, including chimeric antigen receptor (CAR) T cells, to home efficiently into tumor target tissue...

Talimogene laherparepvec is a first-in-class intralesional oncolytic immunotherapy. In a recent Phase III trial (OPTiM), talimogene laherparepvec significantly improved durable response rate compared with subcutaneous granulocyte-macrophage colony-stimulating factor (GM-CSF). Overall response rate was also higher in the talimogene laherparepvec arm, and the greatest efficacy was demonstrated in patients with earlier-stage (IIIB, IIIC, or IVM1a) melanoma. Talimogene laherparepvec was well tolerated, with the majority (89%) of adverse events being grade 1 or 2...

BACKGROUND: In-transit and recurrent dermal or subcutaneous melanoma metastases represent a significant burden of advanced disease. Intralesional Rose Bengal can elicit tumor selective ablation and a T-cell mediated abscopal effect in untreated lesions. A subset of patients in a phase II trial setting received external beam radiotherapy to their recurrent lesions with complete or partial response and no significant acute radiation reaction. METHODS: An open-label, single-arm phase II study was performed to assess the efficacy and safety of PV-10 followed by hypofractionated radiotherapy...

Congenital melanocytic nevi (CMN) are hamartomas present at birth that are composed of nevomelanocytes and thought to originate from faulty migration of precursor melanocytes in the neural crest. Classification is based on projected adult size of the lesion. CMN size correlates positively with risk of melanoma and neurocutaneous melanocytosis. Management requires a patient-centered approach that weighs the risks and benefits of and alternatives to complete removal. All children with large and giant CMN, regardless of surgical status, should be monitored closely and undergo periodic skin examination...

Intralesional therapy of melanoma patients with locally advanced metastatic disease is attracting increasing interest, not least due to its ability to lead to both direct tumor cell killing and the stimulation of both a local and a systemic immune response. An obvious pre-requisite for this type of approach is the presence of accessible metastases that are amenable to direct injection with the therapeutic agent of interest. Patients who present with these characteristics belong to stages IIIB/C or IV of the disease...

Immune mechanisms have evolved to cope with local entry of microbes acting in a confined fashion but eventually inducing systemic immune memory. Indeed, in situ delivery of a number of agents into tumors can mimic in the malignant tissue the phenomena that control intracellular infection leading to the killing of infected cells. Vascular endothelium activation and lymphocyte attraction, together with dendritic cell-mediated cross-priming, are the key elements. Intratumoral therapy with pathogen-associated molecular patterns or recombinant viruses is being tested in the clinic...

Marlana Orloff
On October 27, 2015, talimogene laherparepvec (T-VEC), a first in class intralesional oncolytic virotherapy, was granted the US Food and Drug Administration approval for the treatment of melanoma in the skin and lymph nodes. Its approval has added yet another therapeutic option to the growing list of effective therapies for melanoma. Though the Phase III OPTiM trial has demonstrated its efficacy as a single agent, the target patient population remains narrow. With numerous effective and tolerable treatments available for unresectable and metastatic melanoma, intralesional therapies such as T-VEC are still finding their niche...

INTRODUCTION: Immunotherapy has revolutionized the treatment of metastatic melanoma and dramatically improved patient outcomes. Ipilimumab, an inhibitor of cytotoxic T-lymphocyte antigen-4 (CTLA-4), was the first immunotherapeutic agent to demonstrate improved survival in advanced melanoma. More recently, other immune checkpoint inhibitors, including the programmed death-1 (PD-1) inhibitors pembrolizumab and nivolumab, have demonstrated efficacy in locally advanced unresectable and metastatic melanoma...

Talimogene laherparepvec (Imlygic™) is a first-in-class oncolytic viral immunotherapy derived from herpes simplex virus type 1, which has been genetically modified to increase tumour selectivity and stimulate antitumour immune response. This article reviews the pharmacological properties of intralesional talimogene laherparepvec and its clinical efficacy and tolerability in patients with unresectable metastatic melanoma. In the phase III OPTiM trial, talimogene laherparepvec was more effective than subcutaneous human granulocyte-macrophage colony-stimulating factor (GM-CSF), both in patients with stage IIIB-IV melanoma [intention-to-treat (ITT) population] and in those with stage IIIB-IVM1a disease (in an exploratory subgroup analysis)...
