BACKGROUND: Inconsistencies in outcome reporting and frequent omission of patient-centered outcomes can diminish the value of trials in treatment decision making. We identified critically important outcome domains in kidney transplantation based on the shared priorities of patients/caregivers and health professionals. METHODS: In a 3-round Delphi survey, patients/caregivers and health professionals rated the importance of outcome domains for trials in kidney transplantation on a 9-point Likert scale and provided comments...

Tissue-resident memory T (TRM) cells have been widely characterized in infectious disease settings; however, their role in mediating immunity to cancer remains unknown. We report that skin-resident memory T cell responses to melanoma are generated naturally as a result of autoimmune vitiligo. Melanoma antigen-specific TRM cells resided predominantly in melanocyte-depleted hair follicles and were maintained without recirculation or replenishment from the lymphoid compartment. These cells expressed CD103, CD69, and CLA (cutaneous lymphocyte antigen), but lacked PD-1 (programmed cell death protein-1) or LAG-3 (lymphocyte activation gene-3), and were capable of making IFN-γ (interferon-γ)...

BACKGROUND: Most studies that examined risk factors for wound complications after head and neck reconstruction analyzed various complications collectively. Moreover, they included a wide variety of resection areas and reconstruction materials. To overcome these limitations, both the resection area and reconstruction method were constrained in the present study. METHODS: Patients who underwent free jejunal graft reconstruction after pharyngolaryngoesophagectomy for hypopharyngeal cancer were enrolled...

Skin cancer is the most common cancer in the United States with over 3.5M annual cases. Presently, visual inspection by a dermatologist has good sensitivity (> 90%) but poor specificity (< 10%), especially for melanoma, which leads to a high number of unnecessary biopsies. Here we use dynamic thermal imaging (DTI) to demonstrate a rapid, accurate and non-invasive imaging system for detection of skin cancer. In DTI, the lesion is cooled down and the thermal recovery is recorded using infrared imaging. The thermal recovery curves of the suspected lesions are then utilized in the context of continuous-time detection theory in order to define an optimal statistical decision rule such that the sensitivity of the algorithm is guaranteed to be at a maximum for every prescribed false-alarm probability...

Melanoma incidence has been increasing in light-skinned populations worldwide, but the reasons for the increase have been controversial. Our prior assessment in California non-Hispanic whites showed substantial increases in invasive melanoma incidence for tumors of all thicknesses in all neighborhoods categorized by socioeconomic status (SES) between 1988-1992 and 1998-2002. To understand whether these trends continued, we updated our assessment to include the diagnosis period 2008-2012 and more accurate pathologic stage at diagnosis...

BACKGROUND: Skin cancer is the most common malignancy after solid organ transplant and can lead to significant morbidity. The likelihood of developing squamous cell carcinomas and melanomas is 100 and 2.4 times more likely, respectively, in kidney transplant recipients when compared with the general population. There are few data regarding the assessment and influence of solid organ transplant recipient (SOTR) knowledge of skin cancer and its effect on short- and long-term awareness and behavior...

MCAM/CD146 (melanoma cell adhesion molecule/CD146) is a transmembrane immunoglobulin superfamily cell adhesion molecule involved in transendothelial migration and signal transduction. It is expressed in melanoma, squamous cell carcinoma, prostatic, ovarian, cervical and endometrial cancers and promotes tumour growth, angiogenesis and metastasis. Melanoma is the most common malignant oral tumour of dogs and also arises in the skin, nail bed and footpad. The aim of this study was to investigate the immunohistochemical expression of MCAM/CD146 in 51 canine melanomas, including oral, cutaneous and ocular tumours...

BACKGROUND: Intravascular large B-cell lymphoma (IVLBCL) is a rare type of extranodal large B-cell lymphoma. It is characterized by the proliferation of tumour cells exclusively intraluminally in small blood vessels of different organs. The clinical manifestation depends on the type of organ affected, additionally, a haemophagocytic syndrome can be observed in some patients. OBJECTIVE: Due to the rarity of this lymphoma and in spite of detailed immunohistochemical investigations the exact nosology of this cancer is only incompletely understood...

NLRP1 was the first NLR protein described to form an inflammasome, recruiting ASC to activate caspase-1, which processes interleukin-1β and interleukin-18 to their active form. A wealth of new genetic information has now redefined our understanding of this innate immune sensor. Specifically, rare loss-of-function variants in the N-terminal pyrin domain (PYD) indicate that this part of NLRP1 is autoinhibitory, and normally acts to prevent a familial autoinflammatory skin disease associated with cancer. In the absence of a ligand to trigger human NLRP1, these mutations have now confirmed the requirement of NLRP1 autolytic cleavage within the FIIND domain, which had previously been implicated in NLRP1 activation...

Breast cancer patients are typically advised to avoid antiperspirants for fear of increasing radiation dermatitis in the axilla. We hypothesized that antiperspirants would have minimal effect on skin dose. We found no difference in surface dose±antiperspirants using 6MV photons at gantry angles of 0°/30°/60°/90° regardless of aluminum concentration.

Skin cancer is one among the many prominent diseases of the modern world and millions of people are suffering due to the lack of proper medication. Even though transdermal drug delivery systems (TDDS) provide an efficient route of drug administration, the advantages of combination chemotherapy have rarely been extended into TDDS. In the present work, a polymer capable of simultaneously encapsulating two anti-cancer drugs: 5-flurouracil (5-FU) and curcumin (CUR), and releasing them with varying kinetics as a function of the leaching solvent was developed...

The eighth edition of the staging manual of the American Joint Committee on Cancer incorporates important changes in the classification of skin cancers. Coming 40 years after the first edition, the latest manual preserves its specific system for Merkel cell carcinoma and takes into account recent publications on the prognosis of squamous cell carcinoma by defining a completely new T category for this neoplasm. Staging for squamous cell carcinoma considers head and neck tumors (excluding the eyelid) and does not offer solutions for other sites except the vulva, penis, and perianal region...

The cell surface protein Stem Cell Antigen-1 (Sca-1) marks stem or progenitor cells in several murine tissues and is normally upregulated during cancer development. Although the specific function of Sca-1 remains unknown, Sca-1 seems to play a role in proliferation, differentiation and cell migration in a number of tissues. In the skin epithelium, Sca-1 is highly expressed in the interfollicular epidermis but is absent in most compartments of the hair follicle; however, the function of Sca-1 in the skin has not been investigated...
