Sequential monitoring of pigmented lesions during dabrafenib treatment: A prospective study and a literature overview
No full textBACKGROUND: Targeted therapies in melanoma have shown clinical benefit in incrementing the overall survival of metastatic patients. However, cutaneous adverse events have been frequently associated with these drugs. METHODS: We report our experience in the management of patients treated with dabrafenib for metastatic melanoma, focusing on the monitoring of pigmented lesions. Dermatologic evaluation was performed during the first visit, at the start of each treatment and subsequently after every four weeks. Global nevi count, videodermoscopy of suspected lesions, and surgical excisions when necessary were performed at the beginning of the treatment and every fourth week. All other cutaneous adverse events (cAEs) were noted and documented. Eleven patients were included. RESULTS: The most important cAEs included palmo-plantar hyperkeratosis, diffuse xerosis and pigmented lesion changes. Regarding the latter, in 6 patients, especially in the first months of treatment, we observed hyperpigmentation and hyperkeratosis of the nevi, of the pigmented mucosae and, in one patient, hyperkeratotic changes on a cutaneous metastasis. Histopathology of the excised lesions showed one ex novo melanoma occurrence and benign changes to pre-existing nevi. CONCLUSIONS: The awareness of the importance of sequential monitoring of pigmented lesions, with particular attention to the lesions of new onset, is crucial for the best management of these complex patients
A single institute's experience on melanoma prognosis: A long-term follow-up
No full textBACKGROUND: The prognosis of cutaneous melanoma is correlated to histopathologic parameters such as Breslow thickness, the presence of mitosis, ulceration and lymphatic involvement at the moment of the diagnosis. On the other hand, the prognostic value of parameters such as age, sex, and tumor localization are still a matter of debate. We evaluated herein the prognostic factors in melanoma patients during a long-term follow-up (60 months). METHODS: Melanoma patients presenting stage IB-III at diagnosis were included. Breslow thickness, ulceration, lymphatic involvement, patients' age, sex and tumor localization were correlated to patients' prognosis. Univariate Cox regressions and multivariate Cox proportionalhazards regression were performed. Successively, Kaplan-Meier was used for variables significantly associated with overall melanoma survival. RESULT S: A total of 115 melanoma patients were included in this study. During follow-up 82 (72.17%) patients survived and 33 (28.7%) died. In our dataset, Breslow thickness >2 mm (P=0.0007), patients age >50 years (P=0.005) and positive sentinel lymph node (P=0.0003) seem to be the most important variables correlated with the presence of metastases at 5 years follow-up. However distant metastases were also observed during follow-up in 14/26 patients presenting negative sentinel lymph node at diagnosis. CONCLUSIONS: Given the vital importance of target drugs and the newly introduced immunotherapies in cutaneous melanoma management, we would suggest that mutational analyses should also be extended to the subgroup of patients presenting microstaging parameters related to a poor prognosis in a long-term follow-up of 60 months
Drug consumption and melanocytic nevi: correlation between oral contraceptives or hormone replacement therapy and a high melanocytic nevi count
No full textFunctional and Anatomical Outcomes of Pars Plana Vitrectomy for Lamellar Macular Hole: Long-Term Follow-Up
No full textBackground: To investigate functional and anatomical outcomes after pars plana vitrectomy (PPV) for lamellar macular hole (LMH) with a long-term follow-up. Methods: An interventional study on 14 patients (16 eyes) with LMH was conducted. The inclusion criteria included a minimum 36-month follow-up after PPV. The preoperative and postoperative best-corrected visual acuity (BCVA) and spectral domain optical coherence tomography parameters were examined. Results: Preoperatively, the mean BCVA was 0.46 ± 0.22 LogMAR. Epiretinal proliferation (ERP) was visible in 81.25% of eyes. Outer retinal disruption was present in 31.25% of LMH cases. The average central foveal thickness (CFT) measured 183.68 ± 61.73 microns. The mean BCVA improved at each follow-up time point: it was 0.24 ± 0.16 LogMAR at 1 month, 0.18 ± 0.15 LogMAR at 6 months, and 0.09 ± 0.11 LogMAR at the last follow-up. There was a statistically significant improvement between BCVA at 1 month and BCVA at 6 months and between BCVA at 6 months and BCVA at the last follow-up (p < 0.001). BCVA improved in all eyes, with 87.5% achieving at least 0.3 LogMAR improvement. The mean CFT at the 1-month follow-up was 211.45 ± 43.55 microns, increased to 248.81 ± 48.51 microns at 6 months, and further increased to 278.37 ± 45.50 microns at the last follow-up. Foveal contour restoration was achieved in all eyes, and those with preoperative ellipsoid zone alterations demonstrated a complete repair of the external retinal layers. No intra or postoperative complications were recorded. Conclusions: In our series, PPV had a high success rate and was associated with a substantial functional improvement in LMH treatment, and this result was maintained and kept increasing until the last follow-up. Long-term follow-up is crucial for a comprehensive evaluation of the healing process and to assess the benefits of the surgical intervention
