RESUMEN
With exponentially increasing numbers of basal cell carcinoma (BCC) of the head and neck region, also the locally advanced BCCs are increasing in number. These tumours are associated with aggressive biological behaviour with invasion of soft tissues, organs or bone and present with wide variation in management strategies. The objectives of the study was to describe the biological behaviour of aggressive BCCs and their clinical presentation in the head and neck region with a series of cases treated in our tertiary hospital, discuss management plans of such complex cases in terms of surgical planning and reconstruction. A series of five cases of aggressive BCC in the head and neck region with involvement of organs such as nose, orbit, temporal bone, facial nerve, paranasal sinuses and mandible was studied. Locally advanced, aggressive BCC should be evaluated and treated as head and neck tumours. Multidisciplinary team (MDT) discussion is advisable wherein the strategies on surgical excision, reconstruction options, facial nerve rehabilitation, indications for prosthesis and further adjuvant treatment such as radiotherapy and chemotherapy are carefully planned.

The objective of this study is to give more insight in the diagnosis, clinical course and therapy of skin adnexal carcinoma of the head and neck. Forty cases of skin adnexal carcinoma of the head and neck treated from 1977 to 2011 were identified by searching the hospitals cancer registration database. After pathology review by a pathologist specialized in skin cancer, 17 cases were excluded. A retrospective chart review of the remaining 23 patients was performed. Clinical course was recorded by endpoints including survival, loco-regional control and recurrence free survival. Prognostic factors considered for analysis were differentiation of the tumor and location of the tumor. Five-year overall survival (OS) was 78 % (95 % CI 61-100 %). Five-year recurrence free survival (RFS) was 58 % (95 % CI 40-84 %). Poor differentiation of the tumor significantly reduced OS (p = 0.002) and RFS (p = 0.01). Tumor location 'face' demonstrated a significantly better survival than other tumor locations (p < 0.001). Local recurrence occurred in five cases, regional metastasis was seen in seven patients, distant metastasis in three patients. Three cases with distant metastases died of disease. Based on the findings of this small group of patients in a tertiary referral center, we conclude that skin adnexal carcinoma is a very rare skin carcinoma that can behave locally aggressive but also has the potential for regional and distant metastasis. The recognition of skin adnexal carcinoma and subsequent wide excision in an early stage of the disease is of major importance for loco-regional control and survival.

BACKGROUNDS AND OBJECTIVES: The aim of this study was to describe the epidemiology and treatment of skin adnexal carcinoma (SAC) in the Netherlands and to identify prognostic factors for survival in patients with SAC. METHODS: We used population-based nationwide data from the Netherlands Cancer Registry with cases diagnosed during 1989-2010 and followed up to February 1st, 2012. RESULTS: A total of 2,220 SACs were diagnosed during 1989-2010 (age-standardized incidence rate 5.3 per million). Incidence increased by 2.7% and 1.7% annually in males and females, respectively. Fifteen different morphological types were registered. The 5-year relative survival rate increased from 80% in 1989-1994 to 91% in 2006-2010. The majority of all patients (91%) received surgery. Adjuvant radiotherapy and/or lymph node dissection was performed in only a minority of cases. The risk of death was significantly higher in patients who did not receive surgery. CONCLUSIONS: The rising incidence of SAC together with the predilection for the head and neck region suggests a role for UV radiation in the carcinogenesis of SAC. Furthermore, we found an improved survival of SAC in the Netherlands between 1989 and 2010. In view of the low proportion of patients receiving adjuvant therapy there may be further room for improving survival.

BACKGROUND: Knowledge about lentigo maligna (melanoma) (LM/LMM) and its associated prognostic clinicopathological characteristics are limited compared to that of non-LM/LMM subtypes. The current study aimed to determine the clinical relevance of the LM/LMM subtype and its influence on recurrence and survival outcomes. METHODS: All consecutive cases of primary cutaneous head and neck LM/LMM treated by wide local excision over a ten-year period were retrospectively reviewed and compared to non-LM/LMM. Clinical outcome and prognostic factors were assessed by cumulative incidence and competing risk analyses. RESULTS: A total of 345 patients were identified. Specific clinicopathological characteristics such as lower median Breslow thickness (1.6 mm versus 2.1 mm; P = 0.013), association with diagnostic sampling errors (17.3% versus 5.2%; P = 0.01), and increased risk of local recurrences due to incomplete resection (18.7% versus 2.3%; P < 0.001), were significantly associated with LM/LMM. Guideline adherence was similar between the two study groups. The positive nodal status at baseline for LMM was low compared to non-LM/LMM (4.2% vs 17.9%; P = 0.037). The LMM subtype, facial localization, and reduced surgical margins (i.e., guideline non-adherence) were not shown to be independent prognostic factors for disease-free, melanoma-specific, or overall survival after correction for competing risks such as patient age and Breslow thickness. CONCLUSIONS: The LMM subtype was not shown to be prognostically different from non-LM/LMM when corrected for other variables of influence such as patient age and Breslow thickness. Reduced resection margins did not seem to affect disease-free, and melanoma-specific survival and warrant LM/LMM-specific guidelines. Further research is needed to evaluate the value of SLNB in LMM patients.

BACKGROUND: Lentigo maligna melanoma (LMM) predominantly presents in the head and neck of the elderly. The value of sentinel lymph node biopsy (SLNB) for LMM patients remains to be determined, as the reported average yield of positive lymph nodes is less than 10%. In this nationwide cohort study, we wanted to identify LMM patients with an increased risk of SLNB-positivity. METHODS: LMM with an SLNB indication according to the 8th AJCC melanoma guidelines were retrospectively identified from the nationwide network and registry of histo- and cytopathology in the Netherlands (PALGA). A penalized (LASSO) logistic regression analysis was performed to determine the optimal combination of clinicopathological factors to predict a positive SLNB. RESULTS: Between 1991 and 2020, 1989 LMM patients met our inclusion criteria. SLNB was performed in 16.7% (n = 333) and was positive in 7.5% (25/333). The false-negative rate was 21.9%. Clinically detectable regional lymph node (LN) metastases were found in 1.3% (n = 25). Clinicopathological characteristics best predictive for SLNB-positivity (Odds ratio; 95% CI) were age (0.95; 0.91-0.99), ulceration 1.59 (0.44-4.83), T4-stage (1.81; 0.43-6.2), male sex (1.97; 0.79-5.27), (lymph)angioinvasion (5.07; 0.94-23.31), and microsatellites (7.23; 1.56-32.7) (C-statistic 0.75). During follow-up, regional LN recurrences were detected in 4.2% (83/1989) of patients, of which the majority (74/83) had no evidence of regional LN metastases at baseline. CONCLUSION: Our findings confirm the limited SLNB-positivity in LMM patients. Based on the identified high-risk clinicopathological features, a nomogram was developed to predict the risk of a positive SLNB.

BACKGROUND: The surgical treatment of lentigo maligna melanoma is associated with high rates of local recurrence. Handheld reflectance confocal microscopy (HH-RCM) allows for in vivo presurgical detection of subclinical lentigo maligna (melanoma) (LM/LMM). METHODS: A single-center retrospective study from December 2015 to July 2017. Frequency and extent of negative surgical margins, and the diagnostic accuracy of presurgical mapping by HH-RCM was determined. RESULTS: Twenty-six consecutive patients with LM/LMM were included. In 45.8%, HH-RCM detected subclinical LM with a sensitivity of 0.90 and specificity of 0.86. The management was changed in two (7.7%) patients. Of the 24 remaining lesions, 95.8% were excised with negative margins with a mean histological margin of 3.1 and 5.3 mm for LM and LMM, respectively. At a mean follow-up of 36.7 months, there was one (4.8%) confirmed recurrence. CONCLUSIONS: Our method of presurgical delineation by HH-RCM appears to provide a reliable method for the surgical treatment of LM/LMM with a limited rate of overtreatment.

OBJECTIVES/HYPOTHESIS: Evaluation of treatment results of orthovoltage X-rays for a selection of previously untreated favorable basal cell carcinomas (BCC) in the head and neck area concerning local control, cosmetic and functional outcome, and toxicity profile. METHODS: A consecutive series of patients with primarily treated BCCs who were irradiated by means of orthovoltage X-rays in the Netherlands Cancer Institute in Amsterdam between January 2000 and February 2015 were retrospectively evaluated. RESULTS: Two hundred fifty-three BCCs in 232 patients were primarily treated with orthovoltage X-rays. The local control rates at 1, 3, and 5 years for this selection of basal cell carcinomas were 98.9%, 97.5%, and 96.3%, respectively. Tumor size was the only significant predictor for local control because BCCs < 20 mm had a significantly higher 5-year local control rate than lesions ≥ 20 mm (96.8% vs. 89.4%, P = 0.041). Acute toxicity healed spontaneously without medical intervention, and late toxicity rates were low. Functional impairments were negligible, and the cosmetic outcome was excellent. CONCLUSION: Orthovoltage therapy for well-selected favorable BCCs in the head and neck area resulted in excellent local control rates, a low toxicity profile, and apparently satisfactory functional and cosmetic outcomes. Orthovoltage irradiation is a good alternative for surgery for BCCs with favorable histologic prognosis at locations that are at risk for postoperative functional or cosmetic changes, such as the nose or canthus.

BACKGROUND: Basal cell carcinoma (BCC) is the most common cancer diagnosed in white populations worldwide. The rising incidence of BCC is becoming a major worldwide public health problem. Therefore, there is a need for more efficient management. OBJECTIVE: The aim of this research is to assess the efficacy and safety of a one-stop-shop (OSS) concept, using real-time in vivo reflectance confocal microscopy (RCM) (Vivascope 1500; Lucid Technologies, Henrietta, NY, USA) as a diagnostic tool, prior to surgical management of new primary BCCs. METHODS: This is a prospective non-inferiority multi-center RCT designed to compare the "OSS concept using RCM" to current standards of care in diagnosing and treating clinically suspected BCC. Patients ≥ 18 years attending our outpatient clinic at the Department of Dermatology, Academic Medical Center, University of Amsterdam, and the Department of Dermatology, the Netherlands Cancer Institute-Antoni van Leeuwenhoek Hospital (Amsterdam, The Netherlands) with a clinically suspected new primary BCC lesion will be considered for enrollment using predefined inclusion and exclusion criteria, and will be randomly allocated to the experimental or control group. The main outcome parameter is the assessment of incomplete surgical excision margins on the final pathology report of confirmed BCC lesions (either by punch biopsy or RCM imaging). Other outcome measures include diagnostic accuracy (sensitivity and specificity) of RCM for diagnosing BCC and dividing between subtypes, and throughput time. Patient satisfaction data will be collected postoperatively after 3 months during routine follow-up. RESULTS: This research is investigator-initiated and received ethics approval. Patient recruitment started in February 2015, and we expect all study-related activities to be completed by fall 2015. CONCLUSIONS: This RCT is the first to examine an OSS concept using RCM for diagnosing and treating clinically suspected BCC lesions. Results of this research are expected to have applications in evidence-based practice for the increasing number of patients suffering from BCC and possibly lead to a more efficient disease management strategy.
