A large percentage of the patients with keratinocyte carcinoma (KC, formerly known as non‐melanoma skin cancer) is of advanced age and often too frail for standard therapies. However, no specific treatment recommendations are given for this population. This review aimed to give an overview of the current literature on the best practice for the treatment of elderly patients with KC. A literature search was performed in MEDLINE, using ‘keratinocyte carcinoma’, ‘elderly’, ‘treatment’ and various synonyms. Case reports, reviews, comments, non‐English literature and studies with a sample size <15 were excluded. After selection, a total of 47 studies were reviewed. Two types of studies were identified, focusing on (I) the effect of age on treatment outcomes and (II) alternative treatment schedules for elderly patients. Studies on surgery, the gold standard, describe larger lesions and defect size in the elderly population. Recurrence rate, complication rate and disease‐specific survival were not affected by age. Depending on the expected morbidity of a suggested (re‐)excision and patient preferences, a conservative watchful waiting policy can be agreed upon as a shared decision. Other common treatment modalities, such as adjuvant radiotherapy, photodynamic therapy and systemic therapy for basal cell carcinoma (BCC), show comparable results in the elderly and younger population. Alternative treatment schedules for elderly patients include primary hypofractionated radiotherapy, which seems effective and well‐tolerated, although research is limited to case series. Additionally, localized and topical treatments seem safe and effective especially for low‐risk tumours. Data are lacking on the efficacy of systemic therapies of metastatic KC in elderly patients. Efficacy of most treatments (with the exception of photodynamic therapy) is not dependent on age. There is need for more research on the efficacy of adjusted treatment modalities, such as hypofractionated radiotherapy and palliative or curative systemic treatment.
Guidelines for cutaneous squamous cell carcinoma of the head and neck do not take the age of the patient into account, but instead assume equal tumour characteristics and prognostic factors for poor outcome in younger and elderly patients. The aim of this study was to compare tumour characteristics of younger (< 75 years) and elderly (≥ 75 years) patients and identify age-specific risk factors for progression of disease, comprising local recurrence, nodal metastasis and distant metastasis. Patient and tumour characteristics were compared using χ2 or Fisher’s exact tests. Multivariable competing risk analyses were performed to compare risk factors for progression of disease, incorporating the risk of dying before developing progression of disease. A total of 672 patients with primary cutaneous squamous cell carcinoma of the head and neck were retrospectively included. Larger tumour diameter, worse differentiation grade and deeper invasion were observed in older patients. In elderly patients, but not in younger patients, tumour diameter ≥ 40 mm, moderate differentiation grade and an invasion depth ≥ 2 mm were independent risk factors for progression of disease.
Sunscreen products are increasingly being used, owing to the rising awareness of the potential dangers of ultraviolet (UV) radiation. Octocrylene (CAS no. 6197-30-4) is a UV filter introduced over 15 years ago that is frequently used in sunscreens and other cosmetic products. Since
Photosensitizing properties of hydrochlorothiazide may increase skin cancer risk. To date, study findings on the association between hydrochlorothiazide use and skin cancer risk are inconsistent, notably regarding confounding and dose-response. The aim of this study was to investigate the association between hydrochlorothiazide use and incidence of skin cancer in a cohort of unselected Caucasian adults, taking dosing into account. As part of the PharmLines Initiative, which links data from the Lifelines Cohort Study and prescription database IADB.nl, patients aged ≥ 40 years were included from Lifelines, a prospective population-based cohort study in the north of the Netherlands. Skin cancer incidence was compared between subjects starting hydrochlorothiazide treatment (n = 608), subjects starting treatment with other antihypertensives (n = 508), and non-antihypertensive long-term medication users (n = 1,710). Cox regression analyses were performed to obtain hazard ratios, adjusted for potential confounders. The risk of any skin cancer, keratinocyte carcinoma, basal cell carcinoma and squamous cell carcinoma was not significantly increased in general hydrochlorothiazide users. A clear association was observed between high cumulative hydrochlorothiazide use (≥ 5,000 defined daily dose; ≥ 125,000 mg) and the risk of any skin cancer (adjusted hazard ratio 5.32, 95% confidence interval (95% CI) 2.40–11.81), keratinocyte carcinoma (adjusted hazard ratio 7.31, 95% CI 3.12–17.13), basal cell carcinoma (adjusted hazard ratio 7.72, 95% CI 3.11–19.16) and squamous cell carcinoma (adjusted hazard ratio 19.63, 95% CI 3.12–123.56). These findings should lead to awareness with high use of hydrochlorothiazide in Caucasian adults.
<b><i>Background:</i></b> Cutaneous squamous cell carcinoma is the second most common malignancy of the skin, often occurring in older patients and in the head and neck area (cSCCHN). Age, life expectancy, and frailty are not taken into consideration by current guidelines. <b><i>Objectives:</i></b> The objective of this study was to evaluate the influence of frailty and life expectancy on guideline deviation, treatment outcomes, and quality of life (QoL) after treatment in patients with cSCCHN. <b><i>Methods:</i></b> Patients with cSCCHN were prospectively included. A geriatric assessment was performed, including the Geriatric 8 (G8), Groningen Frailty Indicator, and Timed Up and Go test (TUG). The Lee index was used to predict a limited life expectancy, and the Adult Comorbidity Evaluation-27 was used as a comorbidity index. QoL was assessed by the Basal and Squamous cell carcinoma Quality of Life (BaSQoL) questionnaire at three time points. <b><i>Results:</i></b> Seventy-seven patients with cSCCHN were included. Frail patients had significantly more high-risk tumours. Guideline deviation occurred in 7.8% and was more common in patients who were frail (G8), with high-risk tumours (≥T2), with a limited life expectancy or an increased TUG. Guideline deviation did not lead more often to progression of disease in our study. No predictors for post-operative complications were found. BaSQoL subscores were very low at each time point and did not change significantly with time in the total group. Frail patients reported more fear of recurrence or new tumours 3 months after treatment, and less concern about other people’s skin 6 months after treatment, compared to non-frail patients. Complication rate, gender, or guideline deviation did not affect any subscale scores. <b><i>Conclusions:</i></b> Assessment of frailty and life expectancy can guide physicians and patients in treatment decisions. Deviation from guidelines towards less aggressive treatment schedules can be considered in frail patients with a limited life expectancy, since it did not negatively affect short-term outcomes or QoL in patients with cSCCHN in our study. However, these results should be confirmed by other, larger prospective studies with a longer follow-up period.
This study collected data about the effect of patient characteristics (life expectancy, frailty and comorbidity) on treat ment decisions in elderly people with keratinocyte carcinoma, by searching PubMed database. Literature about how patient characteristics affect treatment decision is sparse and is mostly based on small retrospective studies. Therefore, it is difficult to give firm recommendations. A "one-size-fits-all" approach to this population is not sufficient: life expectancy, frailty and comorbidities must be taken into account in the decision-making about treatment, and registered using a validated scoring system, especially before major treatment modalities.There are straightforward guidelines for treatment of keratinocyte carcinoma (formerly known as non-melanoma skin cancer); however, there are no clear recommendations specifically for elderly patients. The aim of this review was to provide an overview of the current literature about the effect of patient characteristics, specifically life expectancy, frailty and comorbidity, on treatment decisions in elderly patients with keratinocyte carcinoma, by searching PubMed database. It was found that the literature is limited and based mostly on small retrospective studies. Therefore, it is difficult to give firm recommendations about how to treat elderly people who have keratinocyte carcinoma. A "one-sizefits-all" approach to this population is not sufficient: life expectancy and frailty need to be considered in the decision-making process regarding treatment for elderly people with keratinocyte carcinoma. Among the comorbidity scores, Adult-Comorbidity-Evaluation-27-index seems to have the best prognostic value. Prospective studies are needed to generate more individualized recommendations for this increasing and often vulnerable group.
