Little is known about pain among long-term adult survivors of childhood cancers. The study investigated pain prevalence in this population compared with sibling controls and examined pain-related risk factors. Three self-reported pain outcomes including pain conditions, prescription analgesics used, and pain attributed to cancer and treatment were assessed among 10,397 cancer survivors and 3034 sibling controls from the Childhood Cancer Survivor Study. Pain conditions (pain/abnormal sensation, migraines, and other headaches) were reported by 12.3%, 15.5%, and 20.5% of survivors, respectively; 16.7% of survivors reported use of prescription analgesics, and 21% attributed pain to cancer and treatment. Risks of reporting pain conditions and using prescription analgesics were higher among survivors than siblings, adjusting for sociodemographic factors. Younger age at diagnosis and a history of non-Hodgkin lymphoma, Wilms tumor, or neuroblastoma (compared to leukemia) were associated with greater risk of reporting pain conditions. A history of bone cancer or soft tissue sarcoma (compared to leukemia) was associated with greater risks of using prescription analgesics and cancer-related pain attribution. Non-brain-directed scatter irradiation was associated with elevated risk for migraines and cancer-related pain attribution. Female gender and lower educational attainment were associated with increased reports of all 3 pain outcomes; minority status, unemployment, and being single were associated with greater risks for reporting pain conditions. These findings contribute to the understanding of pain and associated risk factors among adult survivors of childhood cancer and suggest areas of focus for pain intervention.

Cancer pain is not a single entity but a complex pain state involving different pain syndromes, with inflammatory, neuropathic, compressive, and ischaemic mechanisms. Current therapeutic regimens are based largely on opioids, although opioid treatment can lead to many side effects. Studies using animal models of cancer pain are aimed at understanding cancer pain and developing novel therapies. The most frequently reported models are of bone cancer pain, predominantly modelling pain associated with tumour growth within bone marrow. Here we summarise recent findings from studies using animal models of cancer pain and discuss the methodological quality of these studies.

Ewing's sarcoma is a primary bone cancer that mainly affects the long bones. This malignancy is particularly common in pediatric patients. Primary cranial involvement accounts for 1% of cases, with occipital involvement considered extremely rare. In this case study, primary occipital Ewing's sarcoma with a posterior fossa mass and subsequent relapse resulting in spinal seeding is reported. A 3-year-old patient presented with a 1-year history of left-sided headaches, localized over the occipital bone with progressive torticollis. Computed tomography (CT) imaging showed a mass in the left posterior fossa compressing the brainstem. The patient then underwent surgical excision followed by adjuvant chemoradiation therapy. Two years later, the patient presented with severe lower back pain and urinary incontinence. Whole-spine magnetic resonance imaging (MRI) showed cerebrospinal fluid (CSF) seeding from the L5 to the S4 vertebrae. Primary cranial Ewing's sarcoma is considered in the differential diagnosis of children with extra-axial posterior fossa mass associated with destructive permeative bone lesions. Although primary cranial Ewing's sarcoma typically has good prognosis, our patient developed metastasis in the lower spine. Therefore, with CNS Ewing's sarcoma, screening of the entire neural axis should be taken into consideration for early detection of CSF seeding metastasis in order to decrease the associated morbidity and mortality.

An eight-year long case series follow-up study with pediatric bone cancer patients was conducted to compare the occurrence of adverse events associated with aprepitant with official sources of drug information (manufacturer's leaflet, clinical trials, and European Medicines Agency leaflet). All patients admitted were analyzed, representing 192 aprepitant cycles. Anorexia, febrile neutropenia, and headache were observed in frequencies over 43.8 per 100 patients, which was higher than previous estimates. Adverse events were classified as probable or possible, by using Naranjo score. The increased rates of adverse events, especially on the risk febrile neutropenia, warrant further safety studies on this population.

Squamous cell carcinoma of the ear canal is an entity that arises from the stratum spinosum; it is a rare neoplasm, with a low incidence presenting 1 to 6 cases per million inhabitants, so there is little literature on this pathology. The clinical presentation of temporal bone cancer is usually nonspecific, meaning that its diagnosis is always a late-stage discovery. The definitive diagnosis requires biopsy of the lesion for histopathological and immunohistochemical study to establish the behaviour and the degree of differentiation. We present the case of an adult female patient with a clinical history of osteoporosis, diagnosed with chronic otitis media of the left ear of years of evolution, accompanied by purulent secretion of the same ear that did not respond to multiple treatment regimens. The patient also presented with a headache of left temporal predominance refractory to conventional analgesia. Cranial CT scans showed an osteolytic lesion of the left temporal bone with dural invasion. After resection and biopsy of the lesion, moderately differentiated squamous cell carcinoma was confirmed.
