Malignant melanoma: factors affecting the surgical interval from excision biopsy to definitive surgical management

Think before you shave: Factors influencing choice of biopsy technique for invasive melanoma and effect on definitive management

BACKGROUND/OBJECTIVE

Partial biopsies are sometimes used for melanoma diagnosis with anticipated time and cost savings compared to excisional biopsy. However, their impact on subsequent melanoma management is unknown. Determine factors related to choice of partial over excisional biopsy to diagnose invasive melanoma and examine the effect of partial biopsies on definitive melanoma management.

METHOD

Retrospective repeated cross-sectional population-based study through the Victorian Cancer Registry of diagnosed melanomas in 2005, 2010 and 2015. A random sample of 400 patients per year, stratified by tumour thickness, was selected.

RESULTS

A total of 1200 patients had 833 excisional and 337 partial biopsies. Omission of suspected diagnosis on pathology requests affected 46% (532/1151) of all diagnostic biopsies. Diagnostic suspicion did not influence preference for partial over excisional biopsy [Odds Ratio (OR) 1.2, 95%CI 0.8-1.7; P = 0.40]. The partial:excisional biopsy usage ratio was higher in patients aged > 50 years than patients aged <50 years [relative risk ratios (RRR) 1.5; 95%CI 1.0 to 2.2; P = 0.03]. In 34% and 17% of tumours diagnosed with punch and shave, respectively, three procedures were required for definitive excision instead of two, compared with 5% of excisional biopsies When partial biopsy was used, patients were at greater risk of requiring three-staged excisions when controlled for age, anatomical site, melanoma subtype and thickness (RRR 6.7; 95%CI 4.4-10.1; P < 0.001).

CONCLUSION

Diagnostic suspicion does not appear to be a major factor influencing choice of biopsy technique. Using partial biopsy to diagnose melanoma often leads to an extra procedure for definitive treatment compared with excisional biopsy.

When Patients Tell Their Own Stories: A Meta-Narrative Study of Web-Based Personalized Texts of 214 Melanoma Patients' Journeys in Four Countries

Malignant melanoma is an aggressive, recalcitrant disease. Its impact on people can be compounded by the physical and psychosocial consequences of medical management. Providing melanoma patients with patient-centered care that is effective, safe, and supportive throughout their journey requires knowledge of patients' progressive experiences and evolving perspectives. With ethical approval, we undertook a meta-narrative study of 214 experiential accounts of melanoma collected from the personal story sections of melanoma and cancer support websites. Using a narrative approach, we qualitatively examined the care experiences represented in these accounts and identified needs for supportive care in a framework reflective of the personal patient journey. We differentiate these across three key periods: lead-up to diagnosis; diagnosis, treatment, and recovery; and posttreatment and recurrence, and provide a visual representation of the patient journey. This article contributes to the growing body of work that utilizes Internet content as sources of qualitative, experiential health care data.

University Hospital Waterford: 5-year experience of cutaneous melanoma

INTRODUCTION

The incidence of cutaneous melanoma (CM) continues to rise in Ireland. Despite significant advances in melanoma molecular therapy, surgery remains the mainstay of treatment for CM. The University Hospital Waterford (UHW) prospectively maintained CM registry was established in 2010.

AIM

To summarize 5-year experience (2010-2015) of primary CM presenting to UHW.

METHODS

Data were retrospectively obtained from a central electronic pathology and radiology repository augmented by HIPE data and theatre logs. Data collected included patient demographics and clinico-pathological characteristics, specimen number, size, anatomical location, melanoma subtype, Breslow thickness, Clark's level, ulceration, and mitosis.

RESULTS

592 CMs were managed in UHW during the study period. Overall, females comprised the majority of cases with mean age at presentation 60.78 ± 18.29 years. The most commonly affected anatomical location was the lower limb (26.7%) followed by the back (15.1%), upper limb (15.07%), and face (14.40%). Superficial spreading and lentigo maligna were the most common histological subtype accounting for 19.8 and 20%, respectively. Overall, the mean Breslow depth was 2.4 ± 3.7 mm with corresponding Clark's Level III. Sentinel lymph node positivity was 39/103 (37.89%) most commonly located in the axilla (53.8%) and groin (30.7%).

CONCLUSION

There has been a steady increase in the number of cutaneous melanoma presentations over the past 5-years to the South East Cancer Centre. Patients are managed best by prompt surgical excision and multidisciplinary management. Our results are in keeping with international standards and work continues in determining overall 5-year survival and recurrence rates.
