RESUMO

BACKGROUND: Brooke-Spiegler syndrome is a rare autosomal dominant disorder characterized by the continuous development of multiple benign skin appendage tumors. It is treated usually by repeated standard surgery. Here, we present a case study where electrochemotherapy (ECT) with bleomycin was used as an effective alternative approach in treating advanced dermal cylindromatosis of the head and neck in a patient with Brooke-Spiegler syndrome. PATIENTS AND METHODS: A 45-year-old woman presented with multiple recurrent dermal cylindroma lesions on her scalp. Previous treatment consisted of several surgical excisions that resulted in psychological deterioration due to the formation of numerous scars and extensive alopecic areas. ECT was offered to provide tumor removal and disease control and to improve the patient's quality of life. RESULTS: The treatment was well tolerated, and a significant reduction in neoplastic tissue was achieved. Importantly, scalp skin condition significantly improved, regaining a fair follicular density on the margins. CONCLUSION: This report suggests the feasibility of bleomycin ECT as a less invasive alternative option for controlling multiple scalp cylindroma lesions with cosmetically acceptable results, and improving quality of life.

RESUMO

BACKGROUND: Sentinel lymph node (SLN) biopsy in cutaneous melanoma patients evaluates the regional draining basin for occult micrometastatic disease. Occasionally, nonidentification of SLN impairs the acquisition of this important prognostic factor. OBJECTIVES: To investigate the outcomes of melanoma patients with negative lymphoscintigraphic findings and patients who underwent SLN biopsy from 2004 to 2015 ( n = 1200) were retrospectively reviewed for tumor characteristics and clinical outcomes. METHODS: Patients with nonvisualized lymph nodes (NV group) who underwent only preoperative lymphoscintigraphy were separated and compared with a cohort drawn from all melanoma patients who completed the surgical procedure within the same period (V group). RESULTS: A negative lymphoscintigraphic scan was observed in 38 cases (3.2% of all patients). The NV group showed a significantly older age (median 66.0 vs. 48.3 years; P < 0.0001). Head and neck melanomas were more frequent in the NV group compared to the control group (25.1 vs. 7.8%; P = 0.009). Tumor characteristics such as ulceration and Breslow thickness do not influence the lymphoscintigraphy result. No differences were found in overall survival (OS) and disease-free survival (DFS) between the groups. CONCLUSIONS: The nonvisualization of regional lymph nodes by lymphoscintigraphy is more frequent in older patients with head and neck melanomas. From the clinical point of view, no specific recommendation emerged for patients' management because the nonvisualization of the SLN did not show a significant influence on DFS and OS rates. However, lack of knowledge of lymph node status suggests performing a tighter follow-up eventually by ultrasound evaluation of all potential lymph node drainage basins.

RESUMO

Kaposi sarcoma (KS) remains a relevant malignancy in human immunodeficiency virus (HIV)-infected patients with a non-standardized management; despite past suggestions that ritonavir-boosted protease inhibitor (bPI)-based regimens could be preferable, no combination antiretroviral therapy (cART) regimen was demonstrated to outperform the others and the impact of new drugs, drug classes or paradigms was never investigated nor proven better than previous therapeutic regimes. In order to do this, we retrospectively collected data regarding HIV-infected patients with a diagnosis of KS last seen in six Italian centers after 1 January 2013. A total of 104 KS cases in 99 patients was analyzed for 945.34 patient-year follow-up (PYFU). Twenty-six patients had visceral localizations. Thirty-three patients were treated with chemotherapy, four with electrochemotherapy, and 12 with α-interferon (α-IFN). At censor, 22% received a bPI-based, 14% a non-nucleoside reverse transcriptase inhibitor (NNRTI)-based, and 28% an integrase inhibitor (INI)-based standard cART, 24% a less drug regimen and 12% a mega-cART. Twelve recurrence episodes were observed in seven patients for an incidence of 1.27 per 100 PYFU. Two patients with no evidence of recurrence episodes died for other reasons. In our experience, KS recurrence episodes were infrequent. Despite the increasing use of new antiretroviral drug classes and new treatment paradigms, no excess of recurrence episodes was observed in patients receiving such cART regimens.

RESUMO

Skin malignancies of the head and neck inflict significant structural, functional, and cosmetic burdens upon those affected. We retrospectively addressed electrochemotherapy anti-tumour efficacy in head and neck skin cancer patients who were not suitable for standard treatments. Scars' physical characteristics and aesthetics were evaluated using validated scar assessment scales. Among 33 treated patients, 82% experienced a complete tumour response while 18% experienced a partial response. At a median time period of 7 months, 96% of the evaluated scars came close to resembling the normal surrounding skin showing excellent results in terms of restoration to original condition with no deformity and/or distortion and in terms of preservation of functionality, such as oral competence and eye protection. Electrochemotherapy is an effective local anticancer procedure for cutaneous tumours. In the treatment of skin malignancies of the head and neck, especially in non-surgical cases, in the elderly and in patients declining surgery, electrochemotherapy may represent a valid alternative to standard management.

RESUMO

BACKGROUND: Angiosarcoma is an aggressive vascular neoplasm with a high propensity for local recurrence. Electrochemotherapy is an emerging skin-directed therapy, exerting prominent cytotoxic activity, and antivascular effects. Its efficacy in angiosarcoma has not been investigated. METHODS: This multicenter retrospective analysis reviewed patients who underwent electrochemotherapy from 2007 to 2014 for superficial advanced angiosarcomas. Bleomycin was administered intravenously and delivered within tumors by means of percutaneously applied electric pulses, according to the European Standard Operating Procedures for Electrochemotherapy. Tumor assessment was performed using RECIST (version 1.1). Toxicity (CTCAE, v4.0) and local progression-free survival (LPFS) were also evaluated. RESULTS: Nineteen patients (13 with locally advanced and 6 with metastatic angiosarcomas) were treated. Tumor sites were: scalp (n = 5), breast (n = 8), other skin sites (n = 3), and soft tissue (n = 3). Target lesions (n = 54) ranged in size from 1.5 to 2.5 cm (median, 2 cm). Treatment was well tolerated. After 2 months, an objective response was observed in 12/19 (63%) patients, complete in 8 (42%). One-year LPFS within treatment field was 68%. Local symptom improvement included palliation of bleeding (5/19 patients) and pain relief (6/19 patients). CONCLUSIONS: Electrochemotherapy may represent a new locoregional treatment for selected patients with superficial angiosarcomas. J. Surg. Oncol. 2016;114:246-253. © 2016 Wiley Periodicals, Inc.

RESUMO

Dermatofibrosarcoma protuberans (DFSP) is an uncommon cutaneous sarcoma with high recurrence rate. Radical surgery is the treatment of choice, although in cosmetically-sensitive areas such as the head and neck, this option is often not pursued. Electrochemotherapy (ECT) is a minimal invasive anti-tumor modality which is increasingly being used to treat skin metastases from different malignancies. A 31-year-old woman presented with subcutaneous local multirecurring DFSP located at the proximal end of the left eyebrow. ECT was offered as a palliative treatment to avoid radical disfiguring surgery. Two days following ECT, the patient was discharged in good general health. Partial tumor regression was appreciable at two months' follow-up by ultrasound and magnetic resonance imaging. At six months, residual fibrotic tissue was observed; at three years, no evidence of the tumour was detected. In our case, ECT achieved good local tumor control with excellent cosmetic results, preserving the patient's quality of life.

RESUMO

BACKGROUND: Over the past several years the incidence of cutaneous melanoma has rapidly increased. This tumor develops often in-transit metastases that significantly reduce patient survival at 5 years. To improve prognosis and quality of life in patients with melanoma metastases, a mini invasive procedure like electrochemotherapy (ECT) is adopted to remove superficial tissue lesions. To detect the melanoma metastases, high frequency (HF) ultrasound (US) is used. This technique, though, can be time-consuming and it needs an expert operator and a high performing machine. Therefore, we asked whether the US could be replaced or integrated with other less time-consuming techniques such as 18-FDG positron emission tomography/computed tomography (PET-CT) and telethermography (TT). METHODS: Fifteen patients (4 males and 11 females - age range: 63-91) affected whit advanced stage melanoma were enrolled. They presented 52 in-transit metastases as detected by the three techniques used, HF-US, PET/CT and TT within 30 days before ECT. RESULTS: All the 52 lesions were detected by HF-US (100%), 24/52 were detected by PET-CT (42,6%) and 15/52 were detected by TT (27,7%). PET-CT reported 3.7% false positives, while no false positive were reported by TT. CONCLUSIONS: As US detected 100% lesions, compared to the other two techniques used, US, along with clinical examination, has still to be considered as gold standard in the diagnosis of metastatic lesions. US, associated with an exhaustive anamnesis and accurate clinical examination, cannot be replaced by either PET-CT or TT. When US performing devices and experienced operators are not available, though, it is highly recommended to integrate US with at least one of the other techniques. Under certain circumstances, as in the case of obese and non-collaborating patients or in patients with lymphatic stasis, these techniques should be integrated to obtain exact in-transit metastases evaluation.

RESUMO

Radiation recall dermatitis is an acute, rare skin reaction confined to previously irradiated areas that can be triggered by chemotherapeutic drugs (generally doxorubicin and taxanes), which are administrated after radiotherapy. We describe this case report to discuss the timing of the different choice of treatments of progressive Kaposis's sarcoma (KS) disease. KS, the neoplastic disease associated with HHV-8 infection, is still the most commonly diagnosed malignancy in HIV-1 patients, even if its incidence dramatically declined in the highly active antiretroviral therapy (HAART) era. The cutaneous form of disease generally improves with HAART alone or in association with local treatment (cryotherapy, radiotherapy, intralesion chemotherapy), whereas disseminated and/or progressive disease needs to be treated with systemic chemotherapy. In selected patients with progressive disease, systemic and local therapeutic options should be associated. We report a case of a 30-year-old HIV-1-positive man, affected by epidemic cutaneous and mucosal KS, who received several cycles of chemotherapy in succession with radiotherapy and other chemotherapy treatments for disease progression. After 7 months, the end of the last rechallenge with chemotherapy, the patient presented cutaneous painful and ulcerated lesions on the same skin areas previously irradiated.
