AI Article Synopsis
- Australia and New Zealand have the highest skin cancer rates globally, particularly in non-metropolitan areas, with Mohs micrographic surgery (MMS) being the preferred treatment for keratinocyte cancers due to its effective cure rates and reduced tissue loss.
- This study analyzed MMS cases from The Skin Hospital in 2017, comparing tumour and defect sizes between patients from the Sydney Metropolitan Area (SMA) and those from Outside Metropolitan Sydney (OMS), including further breakdown of OMS into Non-Sydney Metropolitan (NSM) and Regional, Rural, and Remote (RRR) groups.
- Results indicated that OMS patients had larger tumours and defects than SMA patients, suggesting that patients outside major cities face barriers to accessing timely specialized care, highlighting the need
Article Abstract
Background: Australia and New Zealand face the world's highest skin cancer rates, with non-metropolitan regions bearing a greater burden. Mohs micrographic surgery (MMS) is the gold-standard treatment for keratinocyte cancers (KCs) due to high cure rates and tissue-sparing benefits. This study evaluates whether Outside Metropolitan Sydney (OMS) patients present with larger tumours and defects than Sydney Metropolitan Area (SMA) patients.
Methods: This retrospective study examined MMS cases at The Skin Hospital in 2017. Patients were divided into Sydney Metropolitan Area (SMA) and Outside Metropolitan Sydney (OMS), with OMS sub-grouped into Non-Sydney Metropolitan (NSM) and Regional, Rural and Remote (RRR). Tumour and defect sizes were compared between OMS, SMA, and RRR and NSM, with additional exploratory analyses assessing surgical outcomes and tumour characteristics.
Results: Of 2073 patients undergoing MMS, 1870 basal cell carcinomas and 203 squamous cell carcinomas were included. Tumours and defects were significantly larger in OMS patients (median tumour size: 0.8 cm, defect size: 2.1 cm) compared to SMA patients (median tumour size: 0.7 cm, defect size: 1.8 cm). No correlation was found between distance travelled and tumour or defect size. SMA patients also had greater flap and primary closures than OMS. Subgroup analysis of RRR and NSM showed no significant difference in tumour or defect sizes.
Conclusions: Patients from OMS presented with larger KCs, suggesting barriers to earlier access to specialised care. This highlights geographic disparities in skin cancer management outside major cities in Australia in the context of MMS, emphasising the need for improved access and dermatological workforce distribution.

The development of targeted therapy for patients with multiple myeloma (MM) is hampered by the low frequency of actionable genetic abnormalities. Gain or amplification of chromosome 1q (1q+) is the most frequent arm-level copy number gain in patients with MM and is associated with higher risk of progression and death despite recent therapeutic advances. Thus, developing targeted therapy for MM patients with 1q+ stands to benefit a large portion of patients in need of more effective management.

Background: Prior studies of participants with breast and other obesity-associated cancers in the Women's Health Initiative (WHI) showed worse mortality and cardiovascular disease (CVD) outcomes for individuals with a higher number of cardiometabolic risk factors at study entry. The purpose of this analysis is to compare the relationship between cardiometabolic abnormalities and mortality among women with and without cancer in the WHI.
Methods: Women with one of five early-stage obesity-associated cancers (breast, colorectal, endometrial, ovarian, and non-Hodgkin lymphoma) and controls without any new or prior history of cancer were selected from the WHI-Life and Longevity after Cancer ancillary study.
Mesh-reinforced reconstruction after abdominal wall desmoid tumor resection: a retrospective analysis of 16 cases.

Department of Hernia and Abdominal Wall Surgery, Peking University People's Hospital, No.11 Xizhimen South Street, Xicheng District, Beijing, 100044, China.
Purpose: Managing the defect after abdominal wall desmoid tumor resection is challenging due to the wide excision required. This report aims to review our institutional experience with mesh-reinforced reconstruction following desmoid tumor resection in the abdominal wall.
Methods: We retrospectively reviewed patients who underwent abdominal wall desmoid tumor resection with mesh-reinforced reconstruction between April 2014 and January 2019.

"Mosaic graft" technique and surgical dermal glue in Mohs micrographic surgery and general dermatologic surgery.
Dermatol Reports

Centro Dermatologico Vdermastudio, Viareggio.
After Mohs micrographic surgery, derm surgeons utilize local flaps, full or partial thickness grafts, with good or acceptable cosmetic results. When we are dealing with older and problematic patients, blood thinner users, and non-collaborative people with large facial neoplasms, using flaps may be very difficult, and grafts become the best choice. Our aim was to assess a technique to graft very easily, quickly, and safely, full-thickness skin grafts in facial wounds, and have good cosmetic results in those older and problematic people.
