Skin cancers are the most common cancers, and are usually the most curable cancers as well. Recent evidence from Cochrane systematic review and randomized controlled trial (RCT) showed that protecting from over-exposure to radiation from the sun is the main way that can lower the risk of skin cancer. Surgery and radiotherapy are the standard treatments for basic cell cancer (BCC), but cosmetic results are better from surgery. Imiquimod cream may be effective for superficial and low-risk BCCs and causes little or no scarring, but more research is needed on this and other drug alternatives. Cryotherapy (freezing) is an alternative to surgery, but surgery is better for preventing recurrence of BCCs. Photodynamic (light) therapy and lasers might be able to remove some BCCs with less scarring, but may not be as effective as surgery to prevent recurrence.
ObjectivesTo analyze the epidemiological characteristics of inpatients with skin cancer in China.MethodsThe medical records of all inpatients with skin cancer in second-level and above hospitals in China from 2015 to 2017 were collected, and the demographic characteristics and regional distribution of inpatients were retrospectively analyzed.ResultsFrom 2015 to 2017, the quantity of inpatients with skin cancer in China increased annually. The ratio of male to female was 1.09 to 1, individuals aged 60 to 70 were high incidence age group, and the occupation was primarily farmers. Guangdong province had the largest quantity of inpatients. Among geographic regions, the proportion of inpatients in East China was the largest (34.20%). Among economic regions, the proportion of inpatients in the east was the largest (45.86%).ConclusionsThe quantity of inpatients with skin cancer in China is on the rise, and there are obvious spatial differences. Therefore, more attention should be paid to the prevention and treatment of skin cancer.
ObjectiveTo investigate the clinical application of the modified bilobed flap in the reconstruction of zygomatic-facial massive defect after resection of skin cancer. Methods Between August 2009 and October 2011, 15 patients with skin cancer in the zygomatic-facial region underwent defect reconstruction using modified bilobed flaps after surgical removal. There were 12 males and 3 females, aged 52-78 years (mean, 64.1 years). The disease duration was 1-14 months (mean, 4.6 months). Among the patients, there were 11 cases of basal cell carcinoma and 4 cases of squamous cell carcinoma; 1 patient had infection and the others had no skin ulceration; and tumor involved the skin layer in all patients. According to TNM staging, 13 cases were rated as T2N0M2 and 2 cases as T3N0M3. The defect size ranged from 4.0 cm × 2.5 cm to 6.5 cm × 4.0 cm after cancer resection. The modified bilobed flaps consisting of pre-auricular flap and post-auricular flap was used to repair the defect after cancer resection. The size ranged from 4.0 cm × 2.5 cm to 6.5 cm × 4.0 cm of the first flap and from 3.0 cm × 2.0 cm to 5.0 cm × 3.0 cm of the second flap. ResultsPartial incision dehiscence occurred in 1 case, and was cured after dressing change; the flaps survived and incision healed primarily in the other cases. Fourteen patients were followed up 12-24 months (mean, 18.7 months). No recurrence was found, and the patients had no obvious face asymmetry or skin scar with normal closure of eyelid and facial nerve function. At last follow-up, the results were very satisfactory in 5 cases, satisfactory in 7 cases, generally satisfactory in 1 case, and dissatisfactory in 1 case. ConclusionThe pre- and post-auricular bilobed flaps could be used to reconstruct the massive defects in the zygomatic-facial region after resection of skin cancer.
