[PMID: 39272941 PMCID: PMC11394667 DOI: 10.3390/cancers16173083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2024] [Revised: 08/26/2024] [Accepted: 09/03/2024] [Indexed: 09/15/2024] Open
Abstract
The management of advanced cutaneous squamous cell carcinoma (CSCC) has been revolutionized by the introduction of immunotherapy. Yet, successful treatment with immunotherapy relies on an adequate antitumor immune response. Patients who are solid-organ transplant recipients (SOTRs) have a higher incidence of CSCC compared to the general population. This review discusses the current knowledge of epidemiology, pathophysiology, and management of patients with CSCC who are immunocompromised because of their chronic exposure to immunosuppressive medications to prevent allograft rejection. First, we discuss the prognostic impact of immunosuppression in patients with CSCC. Next, we review the risk of CSCC development in immunosuppressed patients due to SOT. In addition, we provide an overview of the biological immune disruption present in transplanted immunosuppressed CSCC patients. We discuss the available evidence on the use of immunotherapy and provide a framework for the management approach with SOTRs with CSCC. Finally, we discuss potential novel approaches that are being investigated for the management of immunosuppressed patients with CSCC.

Cureus 2024; 16:e56689.

Abstract
Anaplastic thyroid carcinoma, a rare type of primary thyroid cancer, is one of the most aggressive neoplasms with a poor prognosis. Many cases are in the advanced stage at the time of the initial visit, and curative treatment is impossible. Because of the highly radioresistant nature of anaplastic thyroid carcinoma, this condition cannot be properly controlled with conventional radiotherapy. Herein, we report the case of a patient with anaplastic thyroid carcinoma who underwent hypofractionated radiotherapy, attained a complete response, and is still alive more than 10 years after treatment with no evidence of disease. To overcome the high radioresistance of anaplastic thyroid carcinoma, we administered 50 Gy in 10 fractions three times a week. Furthermore, we administered paclitaxel and carboplatin sequentially before and after radiotherapy. Consequently, the patient completed treatment and reached a complete response. He is still alive more than 10 years after treatment with no evidence of disease or severe adverse events. Hypofractionated radiation therapy may provide good control of locally advanced anaplastic thyroid carcinoma.

Abstract
In order to update recommendations on treatment, supportive care, education, and follow-up of patients with invasive cutaneous squamous cell carcinoma (cSCC), a multidisciplinary panel of experts from the European Association of Dermato-Oncology (EADO), the European Dermatology Forum (EDF), the European Society for Radiotherapy and Oncology (ESTRO), the European Union of Medical Specialists (UEMS), the European Academy of Dermatology and Venereology (EADV), and the European Organisation of Research and Treatment of Cancer (EORTC) was formed. Recommendations were based on an evidence-based literature review, guidelines, and expert consensus. Treatment recommendations are presented for common primary cSCC (low risk, high risk), locally advanced cSCC, regional metastatic cSCC (operable or inoperable), and distant metastatic cSCC. For common primary cSCC, the first-line treatment is surgical excision with postoperative margin assessment or micrographically controlled surgery. Achieving clear surgical margins is the most important treatment consideration for patients with cSCCs amenable to surgery. Regarding adjuvant radiotherapy for patients with high-risk localised cSCC with clear surgical margins, current evidence has not shown significant benefit for those with at least one high-risk factor. Radiotherapy should be considered as the primary treatment for non-surgical candidates/tumours. For cSCC with cytologically or histologically confirmed regional nodal metastasis, lymph node dissection is recommended. For patients with metastatic or locally advanced cSCC who are not candidates for curative surgery or radiotherapy, anti-PD-1 agents are the first-line systemic treatment, with cemiplimab being the first approved systemic agent for advanced cSCC by the Food and Drugs Administration/European Medicines Agency. Second-line systemic treatments for advanced cSCC, include epidermal growth factor receptor inhibitors (cetuximab) combined with chemotherapy or radiotherapy. Multidisciplinary board decisions are mandatory for all patients with advanced cSCC, considering the risks of toxicity, the age and frailty of patients, and co-morbidities, including immunosuppression. Patients should be engaged in informed, shared decision-making on management and be provided with the best supportive care to improve symptom management and quality of life. The frequency of follow-up visits and investigations for subsequent new cSCC depends on underlying risk characteristics.

Abstract
BACKGROUND To evaluate the role of definitive weekly hypofractionated radiotherapy (RT) for the treatment of surgery-ineligible elderly patients with cutaneous squamous cell carcinoma of the head and neck region (cHNSCC). METHODS Eligible elderly patients (aged ≥75 years) with cHNSCC were included. Patients received definitive weekly hypofractionated RT, using megavoltage electrons, to a total dose of 56-64 Gy (8 Gy per fraction). Primary endpoint was objective response rate (ORR), defined as the percentage of patients with a complete (CR) or partial response (PR). Secondary endpoints included duration of response (DOR), progression-free survival (PFS), overall survival (OS), pain response, tolerability, and safety. RESULTS A total of 19 patients with 27 lesions were included and treated with definitive weekly hypofractionated RT. All patients received the prescribed total dose. ORR was 92.6%, including 70.4% of lesions with a CR and 22.2% with a PR. Median DOR was 12 months. No severe toxicity occurred. CONCLUSIONS Our study confirmed the satisfying efficacy and acceptable toxicity of definitive weekly hypofractionated RT for cHNSCC in elderly patients. Our results establish weekly hypofractionated scheduleas a promising treatment option for elderly patients with cHNSCC.

Abstract
INTRODUCTION Non-melanoma skin cancer (NMSC) is becoming ever more prevalent among older adults. However, older adults with NMSC are often underrepresented in clinical trials and guidelines on effective management is still unclear. The International Society of Geriatric Oncology (SIOG) created a multi-disciplinary task force to explore the potential in developing practical guidelines for the treatment of older patients with basal cell carcinoma (BCC) and skin (cutaneous) squamous cell carcinoma (cSCC). MATERIALS AND METHODS A systematic literature search to identify relevant and up-to-date literature on treatment of NMSC in older adults was conducted on various databases including MEDLINE, Embase, CINAHL, Cochrane, and PubMed. The resulting papers were discussed by an expert panel, leading to a consensus recommendation. RESULTS A total of 154 articles were identified for the expert panel to utilise in generating consensus recommendations. A major focus on geriatric assessment and management options including surgery, radiotherapy, systemic therapy, clinical monitoring, and medical/medicophysical therapy were reviewed for recommendations. DISCUSSION Patient age should not be the sole deciding factor in the management of patients with NMSC. Assessment from a multidisciplinary team (MDT) is crucial, and the decision-making process should consider the patient's lifestyle, needs, and expectations. A comprehensive geriatric assessment should also be considered. Patients should feel empowered to advocate for themselves and have their views considered a part of the MDT discussion.

Abstract
INTRODUCTION The optimal definitive radiotherapy (RT) scheme in cutaneous squamous cell carcinoma (cSCC) remains controversial, especially in elderly patients. METHODS Data of elderly patients with cSCC lesion(s) treated with weekly hypofractionated RT (8 Gy per week per 7-8 weeks) were analyzed. RESULTS Eighteen patients (median age 89 years) with 23 cSCC lesions have been identified including nine males (50%) and nine females (50%). The most common tumor localization was the head and neck region (n = 21; 91.3%), and the majority of lesions (n = 15; 65.2%) was stage ≥ III. At diagnosis, pain and bleeding were ascribed in 13 (56.5%) and eight (34.8%) cSCC, respectively. Compliance with weekly hypofractionated RT was excellent. The overall response rate at 12 weeks after treatment was 95.7%. Bleeding and pain relief were achieved in all cases. Severe toxicity was not recorded. The 1-year overall survival was 66.0%. The 1-year progression-free survival was 58.7%. CONCLUSIONS Weekly hypofractionated RT provides a safe, efficient, and cost-effective treatment in elderly cSCC patients with minimal side effects.

Abstract
Non-melanoma skin cancers (NMSC's) are the most common malignancies worldwide. Millions of new cases every year present challenge to healthcare systems. Recent years brought numerous new data concerning High Dose Rate (HDR) brachytherapy as treatment option for NMSC's. International guidelines do not recognize brachytherapy as a method of choice given lack of randomized trials, however many prospective and retrospective studies show promising results. Aim of the study was to present the efficacy of HDR brachytherapy, with analysis of its safety and adverse effects based on review of the English published medical full-text papers. Literature review of thirteen articles published between 1999 and 2021 was performed. Pubmed and Google Scholar databases were searched on October 2021 using keywords: ((Basal cell carcinoma) OR (squamous cell carcinoma) OR (non-melanoma skin cancer)) AND (HDR brachytherapy). Fourteen full text English articles with follow up over 1 year and study group over 50 patients were included into analysis. In analyzed material 2403 patients received High Dose Rate brachytherapy. Local control varied between 71 and 99%.Dominant reported cosmetic effect was good or very good. Results were cross-referenced with recent meta-analyses comparing brachytherapy to surgical excision, Mohs microsurgery and external beam radiotherapy. Radiodermitis is the main adverse effect of radiation treatment during and after radiotherapy. HDR brachytherapy emerges as potentially non-inferior treatment method providing very good reported cosmetic outcomes.

Abstract
Due to the general aging population and the fashion trend of sun exposure, non-melanoma skin cancer (NMSC) is rising. The management of NMSC is difficult and necessitates a multidisciplinary team (i.e., pathologists, dermatologists, medical oncologists, surgeons, and radiation oncologists). When surgery is not an option or will cause unacceptably functional morbidity, radiation therapy (RT) may be a preferable tissue-preserving option. Whether used alone or in conjunction with other treatments, RT has been shown to be quite effective in terms of cosmetic results and local control. Contact hypofractionated RT, brachytherapy, and electronic brachytherapy are all promising new treatments. However, rigorous, randomized trials are missing, explaining the disparity in dose, fractionation, and technique recommendations. Therefore, it is essential that interdisciplinary teams better understand RT modalities, benefits, and drawbacks. Our review will provide the role and indications for RT in patients with NMSC.

Abstract
The increase life expectancy led to an expected increase in skin cancer incidence in older patients. Their treatment can require a complex decision-making process. Limited data are available on characteristics, management and outcome of skin tumours in nonagenarian and centenarian patients. The aim of our study was to describe epidemiology, clinical-pathological features and treatment strategies of skin cancers in a cohort of patients aged ≧95 years. A total of 116 patients ≧95 years of age presented for the evaluation of 225 skin lesions (mean of 1.94 lesions per patient). The mean age was 97.4 years, 57.8% were women. Most patients had an ECOG score of 3 (49.3%) or 4 (32%). Lesions were mainly located on the head and neck area (74.2%), upper (7.1%) and lower (6,2%) limbs. The majority of patients presented with non-melanoma skin cancers (183/225; 81.3%), 25/225 (11.1%) had actinic keratosis, 5 (2.2%) melanoma and 2 (0.9%) atypical fibroxanthoma. Forty-eight lesions (21.3%) were treated with surgery, 58 (25.8%) with radiotherapy. The management of 73 lesion (32.4%) was discussed at the multidisciplinary tumour board meeting. One patient died for the progression of a squamous cell carcinoma; 74 patients died for causes unrelated to skin tumours, 36 are still alive after a mean follow-up of 27.27 months. This cohort study confirms that age is not per se a contraindication for treatment of skin cancers in elderly patients. Our results support the importance of a patient-centred care approach that should take into consideration patient's preferences, comorbidities, compliance and possible adverse events.

Abstract
Cutaneous squamous cell carcinoma (cSCC) is the second most common form of skin cancer, the incidence of which has risen over the last years. Although cSCC rarely metastasizes, early detection and treatment of primary tumours are critical to limit progression and local invasion. Several prognostic factors related to patients' clinicopathologic profile and tumour features have been identified as high-risk markers and included in the stratification scales, but their association with regional control or survival is uncertain. Therefore, decision-making on the diagnosis and management of cSCC should be made based on each individual patient's characteristics. Recent advances in non-invasive imaging techniques and molecular testing have enhanced clinical diagnostic accuracy. Surgical excision is the mainstay of local treatment, whereas radiotherapy (RT) is recommended for patients with inoperable disease or in specific circumstances. Novel systemic treatments including immunotherapies and targeted therapies have changed the therapeutic landscape for cSCC. The anti-PD-1 agent cemiplimab is currently the only FDA/EMA-approved first-line therapy for patients with locally advanced or metastatic cSCC who are not candidates for curative surgery or RT. Given the likelihood of recurrence and the increased risk of developing multiple cSCC, close follow-up should be performed during the first years of treatment and continued long-term surveillance is warranted.

Abstract
Among the non-melanoma skin cancers (NMSC) the squamous cell carcinoma (SCC) is one of the most challenging for the surgeon. Local aggressiveness and a tendency to metastasize to regional lymph nodes characterize the biologic behavior. The variants locally advanced and metastatic require wide excision and node dissection. Such procedures can be extremely detrimental for patients. The limit of the surgery can be safely pushed forward with a multidisciplinary approach. The concept of skin oncoplastic surgery, the ablative procedures and the reconstructive options (skin graft, pedicled flap, microsurgical free flap) are discussed together with a literature review.

Abstract
Introduction The use of radiotherapy for cutaneous squamous cell carcinoma (CSCC) has solid historical roots. It is used with patients who are not suitable for surgery, with patients with high-risk histological features in the adjuvant setting, and in palliative care. Objectives The aim of this article is to summarize and provide a radiation therapy overview on the indications, effectiveness, and potential adverse events of radiotherapy in the adjuvant and advanced setting of CSCC. Methods We performed a comprehensive literature review on PubMed, adopted as our biomedical literature database. Articles were selected based on their date of publication (in the last 30 years) and relevance. Results Radiotherapy (RT) can safely be used to manage non-surgical patients and high-risk patients in the advanced CSCC setting. The remarkable progress of delivery techniques has greatly improved the effectiveness and toxicity profile of RT treatments. From 2D techniques to intensity modulated radiation therapy (IMRT), and brachytherapy, all RT techniques have greatly advanced. To improve acute and chronic side effects, a deeper care has been used. As regards CSCC, several dose fractionations and schedules have been suggested, in line with the patient's age and medical conditions. Conclusions RT is a fundamental and constantly evolving therapeutic option in the treatment of CSCC, to minimize the risk of recurrence and metastases in the adjuvant setting and in the exclusive treatment for non-surgical patients. Patients' selection is crucial, together with and a collaborative team working approach among the specialists involved in disease management in the perspective of the best multidisciplinary assessment.

Abstract
As a result of the coronavirus disease 2019 (COVID-19) pandemic, radiation therapies have been modulated to reduce the risk of infection during outpatient activities and hypofractionated regimens or radiotherapy delay for nonmelanoma skin cancer (NMSC) were suggested. Hypofractionated radiotherapy not only may confer no disadvantage in regard to outcome when compared to a more protracted schedule but might also reduce the risk of infection. We report the experience of a dermatologic radiation therapy department concerning a group of patients with a diagnosis of NMSC selected for a radiation treatment plan aimed to minimize the number of their accesses to our department.

Abstract
Ultra-high-dose rate "FLASH" radiotherapy (FLASH-RT) has been shown to drastically reduce normal tissue toxicities while being as efficacious as conventional dose rate radiotherapy to treat tumors. A large number of preclinical studies describing this so-called FLASH effect have led to the clinical translation of FLASH-RT using ultra-high-dose rate electron and proton beams. Although the vast majority of radiation therapy treatments are delivered using X-rays, few preclinical data using ultra-high-dose rate X-ray irradiation have been published. This review focuses on different methods that can be used to generate ultra-high-dose rate X-rays and their beam characteristics along with their effect on the biological tissues and the perspectives for the development of FLASH-RT with X-rays.

Abstract
BACKGROUND/AIM Cutaneous squamous cell carcinoma (cSCC) is a common type of skin cancer. Options for palliative treatment include systemic agents and radiotherapy. Selection of a radiation regimen should consider the patient's survival prognosis. This study aimed to identify prognostic factors of survival after palliative radiotherapy for cSCC of the head-and-neck. PATIENTS AND METHODS Ten factors were analyzed for survival in 12 patients including age, gender, tumor site, histological grade, primary tumor stage, lymph node involvement, distant metastases, upfront surgery, radiation dose and completion of radiotherapy. RESULTS On univariate analysis, improved survival was significantly associated with lower histological grade (better differentiation) (p=0.022), no distant metastases (p=0.040) and completion of radiotherapy (p=0.014). In the multivariate analysis, lower histological grade (risk ratio=6.05, p=0.100) and completion of radiotherapy (risk ratio=4.87, p=0.115) showed trends. CONCLUSION Predictors of survival were identified that can help design individual treatments. Patients require optimal supportive care as completion of radiotherapy was associated with better survival.

A small case series about safety and effectiveness of a hypofractionated electron beam radiotherapy schedule in five fractions for facial non melanoma skin cancer among frail and elderly patients. ACTA ACUST UNITED AC 2021; 26:66-72. [PMID: 33948304 DOI: 10.5603/rpor.a2021.0013] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Accepted: 12/22/2020] [Indexed: 11/25/2022]
Abstract
Background The aim of the study was to evaluate local control and toxicities of strongly hypofractionated electron beam radiotherapy (RT) in elderly and fragile patients with facial nonmelanoma skin cancer (NMSC). Materials and methods We enrolled patients aged ≥ 65 years with facial NMSC, Karnofsky Performance Status (KPS) ≥ 40 and life expectancy ≥ 6 months, amenable neither to daily RT nor surgery. Radiotherapy consisted of 35 Gy, delivered with 6 MeV electron beam, in 5 fractions of 7 Gy/day twice a week (tw). Prescription isodoses were 100% for cT1-cT2 and 90% for cT3-cT4. Objective response was assessed clinically 4 and 8 weeks after the end of RT and then monitored every 6 months. Side effects were assessed according to the CTCAE scale. Results 12 patients of median age 89.5 years with a total of 23 NMSC cN0 achieved a median follow-up time of 6 months (range 1-10), with total treatment compliance. 10/12 patients had a 40 ≤ KPS < 70 and 2/12 a 70 ≤ KPS < 90. 5/12 patients had synchronous lesions. 22/23 lesions were classified as T1-T2 and had complete response (CR), 1/23 as T4 with partial response (PR). Within 4 weeks after the end of treatment, G1 toxicity was reported for 12/23 lesions, G2 for 8/23, G3 for 3/23, G4 for 0/23, all disappeared 8 weeks later, with or without topical therapy. After last follow-up (1 June 2020) 1/12 patients died with PR from senile marasmus, 11/12 are alive with CR and widely tolerated toxicities. Conclusions Extreme hypofractionation of radiotherapy dose for facial NMSC is effective, safe and suitable for elderly patients.

Abstract
The global COVID-19 pandemic has placed a significant burden on the healthcare sector, overwhelming health services in affected countries worldwide. As healthcare facilities reorganize their services to adapt to this challenging problem, it is important that the sustainability of essential oncology services, including radiotherapy, is maintained. This article describes the Indonesian experience in ensuring sustainability of radiotherapy services during the pandemic, highlighting various important adjustments which were made to allow radiotherapy centers nationwide to continue operating while protecting staff and patients from the risk of disease transmission. As the backlog of patients waiting to start treatment will inevitably grow, some insight on how to proactively manage this issue will also be described.

Abstract
Non-melanoma skin cancer (NMSC) represents the most frequently diagnosed malignancy worldwide, most being cutaneous basal cell and squamous cell carcinoma. The global incidence of NMSC continues to increase as the global population ages. Numerous treatment options are available for NMSC patients, with radiotherapy an efficacious and tissue-preserving non-surgical option. External beam radiotherapy and brachytherapy are modalities with specific indications and advantages in treating NMSC. Where excision is not an option (medically/technically inoperable) or considered less ideal (e.g. cosmetic or functional outcome), radiotherapy offers an excellent alternative. Inoperable elderly and/or co-morbid patients of poor performance status can benefit from short-course hypofractionated radiotherapy, with very acceptable toxicity. Adjuvant radiotherapy in patients with unfavourable pathology can decrease the risk of local and regional recurrence and associated morbidity and mortality. Radiotherapy has advantages and disadvantages and it is important for clinicians to understand these. Managing patients with NMSC is carried out by clinicians from multiple disciplines but it is imperative that they are all aware of the role of radiotherapy in their patients in various clinical settings. Here we aim to discuss the role and indications for recommending radiotherapy in patients with NMSC.

Abstract
INTRODUCTION We report the outcomes of using a combination of cetuximab with radiation therapy (Cetux-RT) to treat a selected group of patients with locally advanced (unresectable) cutaneous squamous cell carcinoma (LA-cSCC). This study presents two-year efficacy and safety data for 8 patients with LA-cSCC treated within a single institution. METHODS Between 2014 and 2017 a total of eight patients (seven males, one female) with LA-cSCC received curative intent treatment with Cetux-RT. All patients received an initial loading dose of cetuximab at 400 mg/m2 seven days prior to radiotherapy, followed by weekly treatment with 250 mg/m2 , continuing through the end of radiotherapy. Radiation doses were 6600 cGy/30 fr (n = 2), 6300 cGy/30fr (n = 2) and 5500 cGy/22 fr (n = 4). RESULTS The median age was 81 years (range, 55-87). The ECOG performance status of all patients was between 0 and 2. With a median duration of follow-up of 25 months (range 10-48 months), five patients remain in a complete response. After a partial response, another patient has relapsed and is receiving palliative chemotherapy, while two patients have died during the period of follow up (one of whom died following progression of disease, the other of an unrelated cause). Treatment in this group of patients was well tolerated, with most toxicities ≤ grade 2, and no toxicities of grade 4/5 reported. CONCLUSIONS Cetux-RT was well tolerated and provided durable disease control within this patient sample. Our data support the use of the Cetux-RT regimen for selected patients with inoperable LA-cSCC and adequate performance status.
