Painful skin lesions and squamous cell carcinoma predict overall mortality risk in organ transplant recipients: a cohort study.

BACKGROUND: Organ transplant recipients (OTRs) have a highly increased risk of cutaneous squamous cell carcinomas (SCCs). Sensation of pain in cutaneous tumours is a powerful patient-reported warning signal for invasive SCCs in OTRs. OBJECTIVES: To investigate the impact of painful vs. painless skin lesions and SCC vs. other skin lesions on the overall mortality risk in OTRs. METHODS: We followed 410 OTRs from 10 different centres across Europe and North America between 2008 and 2015. These patients had been enrolled in an earlier study to define clinically meaningful patient-reported warning signals predicting the presence of SCC, and had been included if they had a lesion requiring histological diagnosis. Cumulative incidences of overall mortality were calculated using Kaplan-Meier survival analysis, and risk factors were analysed with Cox proportional hazard analysis. RESULTS: There was an increased overall mortality risk in OTRs who reported painful vs. painless skin lesions, with a hazard ratio (HR) of 1·6 [95% confidence interval (CI) 0·97-2·7], adjusted for age, sex and other relevant factors. There was also an increased overall mortality risk in OTRs diagnosed with SCC compared with other skin lesions, with an adjusted HR of 1·7 (95% CI 1·0-2·8). Mortality due to internal malignancies and systemic infections appeared to prevail in OTRs with SCC. CONCLUSIONS: We suggest that OTRs have an increased overall mortality risk if they develop painful skin lesions or are diagnosed with cutaneous SCC.

Pain identifies squamous cell carcinoma in organ transplant recipients: the SCOPE-ITSCC PAIN study.

Organ transplant recipients (OTR) are at high risk for cutaneous squamous cell carcinomas (SCC). We aimed to define clinically meaningful patient-reported warning signals predicting the presence of invasive SCC.Patient-reported signs and symptoms of 812 consecutively biopsied skin lesions from 410 OTR were determined by questionnaire and physical examination and related to the subsequent biopsy-proven diagnoses. Receiver-operating characteristic (ROC) curve analyses were used as a measure of distinction between the predictive values of patient-reported warning signals and the occurrence of SCC. Pain was an independent predictive patient-reported warning signal for a biopsy-proven invasive SCC. The odds ratio from the fully adjusted model predicting SCC was 4.4(95% confidence interval: 2.4­8.2). Higher scores on the visual analog scale (VAS) for pain were associated witha greater likelihood for the presence of SCC compared to none or mild pain. The for scores on the VAS from 1to 3, 4 to 6 and 7 to 10 were 4.9 (2.2­10.5), 2.3 (0.96­5.5)and 16.5 (3.6­75.8), respectively. Pain is the most powerful patient-reported warning signal for invasive cutaneous SCC in OTR. Empowerment of patients by education could accelerate diagnosis and treatment of cutaneous SCC.

Oral complications in the treatment of cancer patients.

While treatment for cancer in terms of chemotherapy and radiation therapy have evolved significantly since their inception, both of these cancer treatment modalities, especially if used in combination (e.g., as with head and neck cancers), have a very real potential to result in painful and debilitating adverse effects that clearly decrease quality of life and, potentially, increase mortality due to cancer. Herein, we discuss the prevalence and etiology of three broad categories of oral complications found during the treatment of cancer patients: mucositis, dysgeusia, and infectious disease. Lastly, we present therapeutic options that may be helpful in ameliorating these uncomfortable and, sometimes, life-threatening oral complications.
