Addressing the unmet needs of patients with BRAF-mutated melanoma in Latin America: Expert perspective.

Melanoma represents an increasing public health burden with extensive unmet needs in Latin America (LA). A mutation in the gene is present in approximately 50% of all melanomas in White populations and is a target of precision medicine, with the potential to dramatically improve patient outcomes. Thus, increased access to testing and therapy is LA must be explored.

Merkel cell carcinoma in Latin America: a contribution from an expanded access program for avelumab to address issues from experts' recommendations.

Background: Merkel cell carcinoma (MCC) is an aggressive malignancy, associated with poor outcomes in patients with metastatic disease (mMCC). Management has been dramatically altered as a result of incorporating immune checkpoint blockade agents. MCC data from Latin America (LATAM) come from case-series or individual records.

Melanoma early detection and awareness: how countries developing melanoma awareness programs could benefit from melanoma-proficient countries.

Risk factors for melanoma are well known and have guided plans for primary and secondary prevention. The presentation of the disease, however, varies widely depending on the geographic area, ethnicity, and socioeconomic status. For this reason, many countries have developed specific strategies to increase public awareness and favor early diagnosis.

Side effects and toxicities of targeted therapies in stage IV melanoma.

As the incidence of melanoma continues to increase worldwide, the search for new therapies for advanced (stage IV) melanoma brings with it new patterns of toxicity to contend with. This review covers the toxicity profiles of new treatments for advanced melanoma currently in development. Therefore, the latest literature on melanoma treatment was surveyed for data on reported toxicities.

Maintenance treatment with chemotherapy and immunotherapy in non-small cell lung cancer: a case report.

A 53-years-old woman was diagnosed with lung adenocarcinoma state IV (synchronous pleural involvement) in April 2009. First-line systemic treatment included six cycles of Carboplatin, Paclitaxel, and Bevacizumab. Partial response was achieved.

Cutaneous melanoma in Latin America: the need for more data.

Objective: To identify the scientific literature on cutaneous melanoma in Latin America and compile all available epidemiologic data to demonstrate the need for reliable regional and country-specific data on incidence and mortality estimates.

Methods: Literature searches were conducted in PubMed, Embase, LILACS, and Google Scholar databases for epidemiologic studies from 1 January 2000 to 31 October 2010 related to melanoma in Argentina, Brazil, Colombia, Mexico, Puerto Rico, and Venezuela. A final search on melanoma cases was carried out using country-specific population-based cancer registries.

Molecular detection of circulating tyrosinase mRNA: optimization in a preclinical xenograft mouse melanoma model and further evaluation in samples from advanced melanoma patients.

We designed high-affinity primers for the mRNA sequence of human tyrosinase to test the value of molecular detection of circulating melanoma cells by reverse transcription-polymerase chain reaction (RT-PCR). The optimization process included in vitro settings and in vivo studies in a xenograft mouse model. We detected tyrosinase expression with at least 40 pg and 1.

Cellular and humoral immune response to N-Glycolyl-GM3 elicited by prolonged immunotherapy with an anti-idiotypic vaccine in high-risk and metastatic breast cancer patients.

In this study, the immunogenicity and toxicity profile of 1E10, an anti-idiotypic vaccine mimicking the N-glycolyl-GM3 ganglioside, was investigated with an extended vaccination protocol. The year-long vaccination scheme consisted of 6 biweekly intradermal injections (induction phase), followed by 10 monthly boosters (maintenance). Nineteen patients with high-risk (stage III) or metastatic breast cancer were vaccinated with different dose levels of 1E10 (0.

Active specific immunotherapy of melanoma with a GM3 ganglioside-based vaccine: a report on safety and immunogenicity.

A novel cancer vaccine was obtained by combining GM3 ganglioside with Neisseria meningitidis outer membrane protein complex to obtain very-small-size proteoliposomes (GM3/VSSP). The authors report the results of a phase 1 study of intramuscular administration of GM3/VSSP/Montanide ISA 51 to patients with metastatic melanoma. Twenty-six patients were included in three dose-level cohorts of 120, 240, and 360 mug.
