Prognostic significance of sentinel lymph node biopsy in elderly with cutaneous melanoma: systematic review and meta-analysis.

Sentinel lymph node biopsy is the most powerful prognostic indicator to date for cutaneous melanoma. Even though elderly patients have a lower incidence of sentinel node involvement, its results are still necessary for access to adjuvant therapies. This is highly relevant considering that the Western population shows an aging trend, and the incidence of melanoma has grown exponentially over the years, making elderly patients more likely to die from melanoma than younger ones. We performed a systematic review to investigate the prognostic significance of sentinel lymph node biopsy in elderly patients with melanoma. The systematic review was conducted following the PRISMA guidelines and registered in PROSPERO. The authors searched the Cochrane Database, EMBASE, PubMed, and WOS. Eligible studies for the systematic review were clinical trials, observational population studies, clinical or hospital-based cohort studies, and case-control studies. The meta-analysis was conducted using the R software program applying the meta package. Six reports were identified to meet the inclusion criteria. All studies were retrospective, non-randomized cohorts. The results obtained in this systematic review show a statistically significant influence of sentinel lymph node biopsy on disease-specific survival (HR = 2.87; 95% CI: 1.73-4.74) but also suggest that a positive result negatively impacts disease-free survival (HR = 3.41; 95% CI: 0.96-12.11). This meta-analysis shows that a positive sentinel lymph node biopsy does not imply differences in overall survival but significantly influences disease-specific survival and suggests an unfavorable impact on disease-free survival.

Survival of Women Previously Diagnosed of Melanoma with Subsequent Pregnancy: A Systematic Review and Meta-Analysis and a Single-Center Experience.

Melanoma incidence has increased over the last few decades. How the prognosis of a previously diagnosed melanoma may be affected by a woman's subsequent pregnancy has been debated in the literature since the 1950s, and the outcomes are essential to women who are melanoma survivors in their childbearing years. The main objective of this systematic review is to improve the understanding of whether the course of melanoma in a woman may be altered by a subsequent pregnancy and to help clinicians' diagnosis. Eligible studies for the systematic review were clinical trials, observational cohort studies and case-control studies that compared prognosis outcomes for non-pregnant patients with melanoma, or pregnant before melanoma diagnosis, versus pregnant patients after a diagnosis of melanoma. The search strategy yielded 1101 articles, of which 4 met the inclusion criteria for the systematic review. All the studies were retrospective non-randomised cohorts with patients with melanomas diagnosed before pregnancy. According to our findings, a subsequent pregnancy was not a significant influence on the outcome of a previous melanoma. However, given the small number of identified studies and the heterogeneous data included, it is recommended to approach these patients with caution, and counselling should be given by known prognostic factors. We also reviewed the medical records of 84 patients of childbearing age (35.8 ± 6.3 years, range 21-45 years) who were diagnosed with cutaneous invasive melanoma in our hospital between 2008 and 2018 (N = 724). Of these, 11 (13.1%) had a pregnancy after melanoma diagnosis (age at pregnancy: 35.6 ± 6.3 years). No statistical differences in outcome were detected.

Teledermatology: diagnostic reliability in 383 children.

BACKGROUND: There are few studies of teledermatology focused on the pediatric age group. The aim of this study was to assess the validity and reliability of store-and-forward teledermatology (STD) as a diagnostic tool for pediatricians and to reduce face-to-face consultations. MATERIAL AND METHODS: A retrospective, observational study of 383 children and adolescents under 15 years of age, referred from primary care to Dermatology Department of University Hospital of La Coruña, Spain, between 2011 and 2013, using a STD consult system. RESULTS: Diagnoses concordance between pediatricians and teledermatologists was 39.2% of cases and partial concordance 16.7%. Agreement for global diagnosis was κ = 0.78 (p = 0.000) and for specific diagnosis was κ = 0.73 (p = 0.000). Management was concordant in 28.7% and partially concordant in 15.4%. Lower reliability was statistically associated with modification of the lesions by inappropriate treatments, incomplete clinical data or bad-quality photographic images included in the referral consultation, diagnosis of infectious diseases and rare dermatoses. The filtering percentage (as the percentage of avoided clinic-based evaluations) was 64.5%. The mean response time of the consultant dermatologists was 3.62 days. Referrals for live consultations due to poor clinical information or insufficient quality of pictures were necessary in only 10% of the cases. CONCLUSION: The degree of diagnostic accuracy for the pediatric population using STD as a diagnostic tool was similar to that achieved in adults. Its usefulness for filtering dermatologic referral was also demonstrated in the study, so it could be suitable for integration into the routine practice of pediatricians.
