ABSTRACT

Mohs micrographic surgery (MMS) is a precise and effective method commonly used to treat high-risk basal cell carcinoma and squamous cell carcinoma on the head and neck. Although the majority of evidence for MMS relates to keratinocyte cancers, there is published evidence for other types of skin cancer. This review aims to discuss the evidence for using MMS to treat six different types of skin cancer [malignant melanoma, lentigo maligna, dermatofibrosarcoma protuberans, atypical fibroxanthoma (AFX), microcystic adnexal carcinoma and pleomorphic dermal sarcoma (PDS)] particularly in the context of survival rates and cancer recurrence. These cancers were chosen because there was sufficient literature for inclusion and because MMS is most useful when cancers are contiguous, rather than for cancers with marked metastatic potential such as angiosarcoma or Merkel cell carcinoma. We searched MEDLINE, PubMed and Embase using the keywords: 'melanoma', 'mohs micrographic surgery', 'lentigo maligna', 'dermatofibrosarcoma protuberans', 'atypical fibroxanthoma', 'microcystic adnexal carcinoma' and 'pleomorphic dermal sarcoma' along with their appropriate synonyms, to identify the relevant English-language articles from 2000 onwards, given that literature for MMS on nonkeratinocyte cancers is sparse prior to this year. AMSTAR (A MeaSurement Tool to Assess systematic Review) was used to assess the validity of systematic reviews. Further high-quality, multicentre randomized trials are necessary to establish the indications and efficacy of MMS for rarer cancers, particularly for AFX and PDS, for which only limited studies were identified.

ABSTRACT

OBJECTIVES: Problem bladder pain syndrome/interstitial cystitis (BPS/IC) is a heterogeneous disorder with variation in management worldwide. Phenotyping aims to personalize therapy and optimize outcomes. The most well-described phenotype is Hunner lesion disease (HLD). The prevalence of HLD and outcome of phenotype-directed management in the UK is not well-studied. We describe the management of a contemporary cohort of patients with BPS/IC in the UK. METHODS: Retrospective analysis of all patients with BPS/IC from January 2015-November 2018. Outcomes of patients who underwent laser ablation to Hunner lesions were collected using the Global Response Assessment tool. RESULTS: One hundred and sixty-three patients (mean age of 43 years [20-85]) were included. 78% were female and patients had experienced symptoms for an average 6 years (1-30) prior to specialist assessment. Eighty-three percent of patients had pelvic imaging (44% ultrasound, 42% magnetic resonance imaging and 14% computed tomography), and a relevant abnormality was found in five (4%). Twenty-two patients (14%) had HLD (International Society for the Study of BPS [ESSIC] 3), with a mean bladder capacity of 373 mL (175-650 mL); 77% were ESSIC C on histopathology. All patients with HLD underwent laser ablation, with 55% experiencing a moderate/marked improvement in symptoms, with a mean duration of effect of 10 months (3-36); 27% of patients had a repeat treatment. CONCLUSIONS: The presence of HLD in patients with BPS/IC is not uncommon. Pelvic imaging rarely identifies any cause for pain and so cystoscopy under anesthesia is essential for accurate phenotyping. Phenotype-directed management with holmium laser ablation to Hunner lesions has good short-term efficacy in improving pain, but re-intervention is often required.

ABSTRACT

OBJECTIVES: To determine if the presence of non-urothelial variant histology (NUVH) is associated with a poorer prognosis following radical cystectomy (RC) compared to pure urothelial carcinoma (PUC). PATIENTS AND METHODS: A prospectively maintained database of all patients undergoing RC at a high-volume regional tertiary bladder cancer service between January 2010 and January 2017 was retrospectively analysed looking for patients with NUVH. Multivariate Cox proportional hazards regression analysis was used to determine disease recurrence, overall survival and bladder cancer-specific survival, as well as lymph node positivity. Association of tumour stage was determined using chi-squared analysis. RESULTS: In total, 430 patients underwent RC of which 73 (17%) had NUVH and 357 (83%) had PUC. The median (range) follow-up was 45.0 (8.5-100.2) months. The presence of NUVH was associated with both increased overall (hazard ratio [HR] 1.86, 95% confidence interval [CI] 1.21-2.85) and bladder cancer-specific mortality (HR 1.81, 95% CI 1.91-3.01), as well as disease recurrence (HR 1.71, 95% CI 1.06-2.75) in multivariate analysis. Squamous cell variant was also associated with increased overall mortality (HR 1.91, 95% CI 1.16-3.13), cancer-specific mortality (HR 2.03, 95% CI 1.21-3.42) and disease recurrence (HR 2.08, 95% CI 1.23-3.52), although this was not seen in other variant subtypes. Lymph node positivity was not associated with NUVH in multivariate analysis (HR 1.28, 95% CI 0.59-2.75), but NUVH was associated with advanced tumour stage on chi-squared analysis (P < 0.001). CONCLUSION: Our results showed a risk of shorter survival in NUVH compared to PUC. This suggests NUVH as an independent predictor of worse outcomes. As a result, patients with NUVH should be counselled preoperatively that overall and disease-specific outcomes are worse postoperatively and about the possible need for adjuvant treatment.
