Familial Melanoma: Diagnostic and Management Implications

Background: An estimated 5%-10% of all cutaneous melanoma cases occur in families. This review describes susceptibility genes currently known to be involved in melanoma predisposition, genetic testing of familial melanoma patients, and management implications.Results: CDKN2A is the major high-penetrance susceptibility gene with germline mutations identified in 20%-40% of melanoma families. A positive CDKN2A mutation status has been associated with a high number of affected family members, multiple primary melanomas, pancreatic cancer, and early age at melanoma onset. Mutations in the other melanoma predisposition genes-CDK4, BAP1, TERT, POT1, ACD, TERF2IP, and MITF-are rare, overall contributing to explain a further 10% of familial clustering of melanoma. The underlying genetic susceptibility remains indeed unexplained for half of melanoma families. Genetic testing for melanoma is currently recommended only for CDKN2A and CDK4, and, at this time, the role of multigene panel testing remains under debate. Individuals from melanoma families must receive genetic counseling to be informed about the inclusion criteria for genetic testing, the probability of an inconclusive result, the genetic risk for melanoma and other cancers, and the debatable role of medical management. They should be counseled focusing primarily on recommendations on appropriate lifestyle, encouraging skin self-examination, and regular dermatological screening.Conclusions: Genetic testing for high-penetrance melanoma susceptibility genes is recommended in melanoma families after selection of the appropriate candidates and adequate counseling of the patient. All patients and relatives from melanoma kindreds, irrespective of their mutation status, should be encouraged to adhere to a correct ultraviolet exposure, skin self-examination, and surveillance by physicians

Early Diagnosis of Melanoma and Breast Cancer in Women: Influence of Body Image Perception

The diagnosis of melanoma and breast cancer may impact many aspects of life with significant reductions in emotional functioning and quality of life. The aim of the study was to analyze the emotional traits of female patients with oncological in early-stage diagnosis, investigating predictors for psychological distress and analyzing body image perception. An observational study was conducted, A sample of 84 female cancer patients (age range 30–55 years) with melanoma (n = 42) and breast cancer diagnosis (n = 42). The examined emotional variables were psychological distress; depression, stress, and anxiety; metacognitions; and body self-perception. Findings showed higher psychological distress in breast cancer than in melanoma patients (p = 0.00), which was related to lower positive self-perception of body image (p = 0.03). Furthermore, psychological distress was negatively correlated with consequences of clinical treatment on body image, and low well-being affected the social interaction and well-being with own body. There was no significant difference between cancer staging and timing from diagnosis. Prevention and therapeutic psychological protocols might be adapted and tailored to the unmet needs of the patients in medical treatments to promote and enhance the Quality of Life in survivorship

Intralesional Methotrexate for the Treatment of Advanced Keratinocytic Tumors: A Multi-Center Retrospective Study

Abstract Introduction Keratinocyte tumors (KT) are frequently observed. Surgery is the treatment gold standard. In some cases, a surgical approach might not be the best option. Radiotherapy (RT) and systemic treatments can frequently cause side effects or be contraindicated. Intralesional methotrexate (MTX) can be a conservative yet effective alternative. We decided to evaluate the effectiveness and safety of intralesional chemotherapy with MTX for the treatment of squamous cell carcinoma (SCC), keratoacanthoma (KA), and basal cell carcinoma (BCC). Methods All patients had a histologically confirmed diagnosis of BCC, SCC, or KA and no indication to surgery or RT. MTX was injected subcutaneously proceeding from the periphery of the lesion toward the center. Different protocols in terms of dose, frequency, and length of treatment were used to compare them. Treatment efficacy was evaluated in terms of tumor size reduction. Patients were divided into three groups: responders (improvement of more than 50%), partial responders (< 50%), and non-responders (no improvement or worsening). All data were analyzed using the chi-squared test (χ 2). Results Thirty-five patients were included. Twenty-one patients suffered from SCC, 12 from KA, and 2 from BCC. KA showed a higher response rate than SCC and BCC. For AK, 92% of patients had a complete resolution; 8% were partial responders. For SCC, 47.6% of cases were responders and 14.3% partial responders, while 38% non-responders. All BCCs showed no improvement. A treatment protocol of weekly injections, performed for 4 to 6 weeks, was the most efficient. Doses of 25 mg/ml per session seemed to be most effective. About one third of our patients developed side effects with mild anemia being the most frequent. Conclusions For selected cases, intralesional MTX can be a safe and effective option for the treatment of KT, especially in case of KA and, to a lesser extent, SCC

Clinical Outcomes of Patients with Advanced Cancer and Pre-Existing Autoimmune Diseases Treated with Anti-Programmed Death-1 Immunotherapy: A Real-World Transverse Study

Background: Patients with a history of autoimmune diseases (AIDs) have not usually been included in clinical trials with immune checkpoint inhibitors. Materials and Methods: Consecutive patients with advanced cancer, treated with anti-programmed death-1 (PD-1) agents, were evaluated according to the presence of pre-existing AIDs. The incidence of immune-related adverse events (irAEs) and clinical outcomes were compared among subgroups. Results: A total of 751 patients were enrolled; median age was 69 years. Primary tumors were as follows: non-small cell lung cancer, 492 (65.5%); melanoma, 159 (21.2%); kidney cancer, 94 (12.5%); and others, 6 (0.8%). Male/female ratio was 499/252. Eighty-five patients (11.3%) had pre-existing AIDs, further differentiated in clinically active (17.6%) and inactive (82.4%). Among patients with pre-existing AIDs, incidence of irAEs of any grade was significantly higher when compared with patients without AIDs (65.9% vs. 39.9%). At multivariate analysis, both inactive (p =.0005) and active pre-existing AIDs (p =.0162), female sex (p =.0004), and Eastern Cooperative Oncology Group Performance Status <2 (p =.0030) were significantly related to a higher incidence of irAEs of any grade. No significant differences were observed regarding grade 3/4 irAEs and objective response rate among subgroups. Pre-existing AIDs were not significantly related with progression-free survival and overall survival. Conclusion: This study quantifies the increased risk of developing irAEs in patients with pre-existing AIDs who had to be treated with anti-PD-1 immunotherapy. Nevertheless, the incidence of grade 3/4 irAEs is not significantly higher when compared with control population. The finding of a greater incidence of irAEs among female patients ranks among the “hot topics” in gender-related differences in immuno-oncology. Implications for Practice: Patients with a history of autoimmune diseases (AIDs) have not usually been included in clinical trials with immune checkpoint inhibitors but are frequent in clinical practice. This study quantifies the increased risk of developing immune-related adverse events (irAEs) in patients with pre-existing AIDs who had to be treated with anti-programmed death-1 immunotherapy. Nevertheless, their toxicities are mild and the incidence of grade 3/4 irAEs is not significantly higher compared with those of controls. These results will help clinicians in everyday practice, improving their ability to offer a proper counselling to patients, in order to offer an immunotherapy treatment even to patients with pre-existing autoimmune disease
