Outcomes of skin cancer excision in frail patients: A retrospective cohort study

BACKGROUND

Non-melanoma skin cancer (NMSC) is the most common cancer type and incidence increases with age. As a consequence, an increasing number of frail patients are being referred for consideration of skin cancer surgery. However, some of these patients may not live long enough to experience benefit from surgery, while being at risk of postoperative complications.

OBJECTIVES

To investigate the treatment burden of surgical excision of skin cancers in frail individuals.

METHODS

We conducted a single-center retrospective cohort study analyzing outcomes of skin cancer excision in frail versus non-frail patients.

RESULTS

Eighty-eight patients were included. The complication rate was higher in frail versus non-frail patients: 12 (27.9%) versus 9 (18.8%), with 5 unplanned postoperative hospital attendances leading to 3 hospital admissions in the frail cohort. Nine patients in the frail group (21%) died within 6 months of their procedure versus no deaths in the non-frail group (p < 0.001 Fisher's Exact test), with no deaths attributed to skin cancer.

CONCLUSION

Treatment-related complications and mortality are common in frail patients after surgical excision of skin lesions clinically suspicious for skin cancer. Careful consideration should be given, and patients should be adequately counseled about treatment risks and alternative management options, including active surveillance, in particular, if the lesions are expected to remain asymptomatic.

An observational analysis of trends in rheumatic heart disease incidence and mortality in EU15+ countries over 29 years

Background

Rheumatic heart disease (RHD) is a debilitating sequela of acute rheumatic fever (ARF), caused by Group A streptococcus (GAS) infection. Repeated episodes of ARF results in valvular damage over time. As a preventable disorder which was once common worldwide, RHD has largely been eradicated in affluent nations due to widespread availability of penicillin, improvement in socioeconomic standards and advancements in health and social infrastructures. However, it has been speculated that the global refugee crisis, especially in Europe, might contribute to a resurgence of RHD cases in these regions.

Purpose

This observational study aimed to analyse trends in RHD incidence and mortality rates in European Union 15+ (EU15+) over a 29-year period.

Methods

Data was obtained from the Global Burden of Disease database. Age-standardised mortality and incidence rates for RHD were extracted for the EU15+ countries for the years 1990–2019. Trends were subsequently analysed using Joinpoint regression analysis.

Results

Over the 29-year period, an overall declining trend in RHD incidence and mortality across EU 15+ nations was observed. The United Kingdom demonstrated the largest decrease in RHD incidence amongst females (−54.9%) and Finland amongst males (−55.3%). Both RHD incidence and mortality were higher among females compared to males across EU15+ countries over the observed period. The most recent incidence trends, starting predominantly after 2014, demonstrated a rise in RHD incidence in most countries. For both sexes, increases were seen in Australia, Belgium, Ireland, Italy, Netherlands, Norway, Sweden and USA. For males specifically, increase in RHD incidence was seen in Spain, and Finland, and for females only in Canada and Ireland. The recent increasing RHD incidence rates ranged from +0.4% to + 24.7% for males and +0.6% to +11.4% for females.

Conclusion

Whilst overall there are decreases in incidence and mortality from RHD, we observe more than half of EU15+ countries have increasing incidence trends in RHD in recent years. This increasing trend primarily started after 2014, overlapping with the start of the European migration crisis. Although speculative, disparities in access to healthcare for migrants, amongst other socioeconomic factors, may be potential causes; subsequently, further efforts by governments and public health officials are required to recognise and control the resurgence of RHD in high income nations.

O045 A systematic review of observational management of cutaneous basal cell carcinoma

Background

Cutaneous basal cell carcinoma (BCC) is the commonest cancer in the United Kingdom. Surgical excision is the most common treatment. This review summarises all published outcomes of observational/non-interventional management of BCC.

Methods

This PRISMA-compliant systematic review searched MEDLINE, EMBASE and CENTRAL databases from inception-June 2021. All studies reporting outcomes of observational management for BCC were included.

Results

From 2529 titles, four full-text articles reporting on 2298 individuals were eligible. Two studies were randomised controlled trials (RCTs) comparing histological clearance rates and adverse events following treatment with an inactive strategy (placebo cream) versus topical 5%-imiquimod (at different frequencies) for 6–12 weeks. Clearance rates ranged from 52–100% for imiquimod and 2–19% for placebo, with more adverse events associated with imiquimod. The other two studies used prospective cohort designs. One study assessed the natural history of BCCs managed expectantly in 39 individuals aged ≥80years. During the 15.8-month follow-up, 46.2% of lesions did not increase in size and 10.3% resolved. The remaining study compared treatment patterns of 1360 patients with non-melanoma skin cancer (NMSC) in individuals with or without limited life-expectancy (LLE). The LLE subgroup had a 5-year mortality rate of 43.3%, with no deaths attributed to NMSC. Only 3.3% of individuals with LLE underwent observational treatment. No study examined quality-of-life or cost-effectiveness.

Conclusion

There has been limited investigation of observational management of BCC, despite possible advantages of this strategy. Future RCTs should compare quality-of-life outcomes and utility adjusted survival following interventional or observational management of BCC.

Take-home message

This systemic review identifies a lack of data reporting outcomes following observational management of BCC, despite possible advantages of this treatment strategy. Future RCTs should compare quality of life outcomes and utility-adjusted survival following interventional or observational management of BCC.
