Laura C Soong, Christopher P Keeling
BACKGROUND: Superficial basal cell carcinoma (sBCC) and squamous cell carcinoma in situ (SCCis) are 2 types of nonmelanoma skin cancers (NMSCs) that are amenable to treatment with topical 5-fluorouracil, cryosurgery, or topical imiquimod, among other destructive and surgical modalities. There are few studies examining the effectiveness of combination therapy with 5% 5-fluorouracil and cryosurgery for the treatment of sBCC and SCCis. OBJECTIVES: Our objective was to study the clinical cure rate achieved with the regimen of cryosurgery and a 3-week course of 5% 5-fluorouracil in the treatment of biopsy-proven sBCC and SCCis...

BACKGROUND AND OBJECTIVES: The standard treatment for cutaneous squamous cell carcinoma (cSCC) is wide local excision (WLE). Incomplete tumor excision is associated with increased recurrence rates and mortality risk. Risk factors for positive margins after WLE of cSCC has been examined in only a few studies. We sought to assess the influence of several clinicopathological factors on margin status in the largest cSCC population to date. METHODS: We performed a retrospective review of records at two skin cancer clinics identifying patients with biopsy-proven cSCC who underwent WLE...

Bufadienolides are a type of cardiotonic steroids isolated from the skin and parotid venom glands of the toad Bufo bufo gargarizans Cantor, and exhibit wide-spectrum anticancer activities. However, the effects and mechanisms of bufadienolides on esophageal squamous cell carcinoma (ESCC) cells remain unknown. In the present study, the anticancer activities of two bufadienolides, bufotalin and bufalin, were examined in vitro and in vivo. The results demonstrated that bufotalin and bufalin effectively inhibited the viability of ESCC cells, with half-maximal inhibitory concentration (IC50) values of 0...

BACKGROUND: Treatment of locoregionally advanced penile squamous cell carcinoma (LAPSCC) is challenging. The exact role (in terms of oncological benefit) of extensive surgery is not well established. Moreover, surgery invariably leads to large defects requiring reconstructive surgery. Rectus abdominis myocutaneous (RAM) and abdominal advancement flaps have an independent and constant blood supply, are easily harvested, and provide substantial skin coverage and soft tissue. OBJECTIVE: To determine the surgical and oncological outcomes in patients with LAPSCC undergoing surgical resection with RAM flaps...

BACKGROUND: Topical photodynamic therapy (PDT) is a highly effective therapy especially for extended cancerized fields of the skin. Whenever extended fields are treated pain management is advisable. Light source mediated pain management can be performed by reducing fluence rates, as long as this does not compromise efficacy. METHODS: Two squamous cell carcinoma cell lines (A431 and SCC-13) were subjected to in vitro PDT using two different ALA concentrations and synthesis intervals and protoporphyrin IX (PpIX) synthesis was assessed...

Nan-Lin Wu, Fu-Tong Liu
The galectin family comprises β-galactoside-binding proteins widely expressed in many organisms. There are at least 16 family members, which can be classified into three groups based on their carbohydrate-recognition domains. Pleiotropic functions of different galectins in physiological and pathological processes through extracellular or intracellular actions have been revealed. In the skin, galectins are expressed in a variety of cells, including keratinocytes, melanocytes, fibroblasts, dendritic cells, lymphocytes, macrophages, and endothelial cells...

Keratin 8/18 the predominant keratin pair of simple epithelia is often aberrantly expressed in various squamous cell carcinomas (SCCs) including skin-SCC. Its aberrant expression is correlated with increased invasiveness and poor prognosis of the same, although the underlying mechanism is still unclear. A previous report from our laboratory has shown K8 mediated regulation of α6β4 integrin signaling and thereby tumorigenic potential of oral-SCC derived cells. Another study on transgenic mouse model has shown that during skin carcinogenesis, K8 favors conversion of papillomas towards malignancy...

Second malignancies are a rare but well-defined late complication after autologous and allogeneic hematopoietic stem-cell transplantation (SCT). Solid malignancies occur in up to 15% of patients 15 years after SCT with myeloablative conditioning, with no plateau in the incidence rates. They are responsible for 5-10% of late deaths after SCT. The incidence is increased with advanced age at SCT. The major risk factors are the use of total body irradiation, which is associated with adenocarcinomas and with chronic graft-versus-host disease which is associated with squamous cell cancers...

Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer and usually progresses from a UV-induced precancerous lesion termed actinic keratosis (AK). Despite various efforts to characterize these lesions molecularly, the etiology of AK and its progression to cSCC remain partially understood. Here, we use Infinium MethylationEPIC BeadChips to interrogate the DNA methylation status in healthy, AK and cSCC epidermis samples. Importantly, we show that AK methylation patterns already display classical features of cancer methylomes and are highly similar to cSCC profiles...

Orocutaneous fistula sometimes occurs in locallyadvanced unresectable or recurrent oral squamous cell carcinoma. The developed orocutaneous fistula results in constant leakage of saliva, ingested foods and liquids and decline in patients' quality of life(QOL). A 47-year-old Japanese man had received treatment for tongue carcinoma. At the routine follow-up, a cystic lesion in the right submandibular region was detected. Biopsyof the specimen of the cystic lesion revealed squamous cell carcinoma. After chemotherapy, an orocutaneous fistula between the right oropharyngeal and the right submandibular region developed and graduallyincreased...

BACKGROUND: vulvar intraepithelial neoplasia is a non-invasive precursor lesion found in 50-70% of patients affected by vulvar squamous cell carcinoma. In the past, radical surgery was the standard treatment for vulvar intraepithelial neoplasia, however, considering the psychological and physical morbidities related to extensive surgery, several less aggressive treatment modalities have been proposed since the late 1970s. Photodynamic therapy is an effective and safe treatment for cutaneous non-melanoma skin cancer, with favorable cosmetic outcomes...

Importance: Squamous cell carcinoma (SCC) is the most common skin cancer diagnosed in solid organ transplant recipients (OTRs) and confers significant mortality. The development of SCC in the genital region is elevated in nonwhite OTRs. Viral induction, specifically human papillomavirus (HPV), is hypothesized to play a role in the pathophysiology of these lesions. Objective: To assess the prevalence and types of genital lesions observed in OTRs. Design, Setting, and Participants: This retrospective review included 496 OTRs who underwent full skin examination from November 1, 2011, to April 28, 2017, at an academic referral center...

Head and neck squamous cell carcinoma (HNSCC) has a high prevalence and is a major cause of cancer deaths in Taiwan. However, there is still no effective salvage therapy that prolongs the life expectancy of patients with recurrent/metastatic (R/M) HNSCC. Immune checkpoint therapy that targets the programmed cell death protein 1 (PD-1) may provide clinical benefit for these patients. We analyzed 22 R/M HNSCC patients who received pembrolizumab, a monoclonal antibody against PD-1, as salvage therapy. Intravenous pembrolizumab was given at a fixed dosage of 100 or 200 mg every 3 weeks...

The myotonic dystrophy-related Cdc42-binding kinases MRCKα and MRCKβ contribute to the regulation of actin-myosin cytoskeleton organization and dynamics, acting in concert with the Rho-associated coiled-coil kinases ROCK1 and ROCK2. The absence of highly potent and selective MRCK inhibitors has resulted in relatively little knowledge of the potential roles of these kinases in cancer. Here we report the discovery of the azaindole compounds BDP8900 and BDP9066 as potent and selective MRCK inhibitors that reduce substrate phosphorylation, leading to morphological changes in cancer cells along with inhibition of their motility and invasive character...
