Abstract Background Ureteral metastasis from gastric cancers are rare and can be a cause of ureteral obstruction. There have been few published case reports in the literature. In this paper, we report an additional case and a review of the literature of all the previous reported cases. Case presentation A 67 years old North African women who was treated four years before for a gastric adenocarcinoma, presented with abdominal pain. Imaging and endoscopy showed a mural stenosis of the left ureter, without any other abnormality. Histopathology confirmed the gastric origin of the metastasis. A palliative chemotherapy was foreseen, but due to the deterioration of the general condition of the patient, she received palliative care. We have also reviewed the literature and reported the previously published cases of ureteral metastasis from gastric cancer. Conclusions It is worth recalling that in a context of neoplasia and with the presence of signs of ureteral obstruction, it is important to keep in mind the possibility of a ureteral metastasis.

Abstract Background The identification of effective prognosis biomarkers for nasopharyngeal carcinoma (NPC) is crucial to improve treatment and patient outcomes. In the present study, we have attempted to evaluate the correlation between pre-treatment plasmatic Epstein-Barr virus (EBV) DNA load and the conventional prognostic factors in Moroccan patients with NPC. Methods The present study was conducted on 121 histologically confirmed NPC patients, recruited from January 2017 to December 2018. Circulating levels of EBV DNA were measured before therapy initiation using real-time quantitative PCR. Results Overall, undifferentiated non-keratinizingcarcinoma type was the most common histological type (90.1 %), and 61.8 % of patients were diagnosed at an advanced disease stage (IV). Results of pre-treatment plasma EBV load showed that 90.9 % of patients had detectable EBV DNA, with a median plasmatic viral load of 7710 IU/ml. The correlation between pre-treatment EBV DNA load and the conventional prognostic factors showed a significant association with patients’ age (p = 0.01), tumor classification (p = 0.01), lymph node status (p = 0.003), metastasis status (p = 0.00) and overall cancer stage (p = 0.01). Unexpectedly, a significant higher level of pre-treatment EBV DNA was also found in plasma of NPC patients with a family history of cancer (p = 0.04). The risk of NPC mortality in patients with high pretreatment EBVDNA levels was significantly higher than that of those with low pre-treatment plasma EBV-DNA levels (p

Abstract Context Dermatomyositis is a rare autoimmune disease characterized by noninfectious inflammatory damage of skin and predominant muscles in the belts. It is believed to be associated with about 1 in 1000 cases of nasopharyngeal carcinoma. This association has been described for locally advanced stages II and III nasopharyngeal carcinoma. It has rarely been described in the early stages (stage I). Case presentation A 65-year-old Moroccan patient residing in Casablanca, with no particular history was referred to the Mohamed VI Center for the treatment of cancers of the University Hospital Center IBN ROCHD in Casablanca, for treatment of nasopharyngeal cancer. He was admitted in poor general condition, performance status 3, with erythema on the face, neck, and extremities. The diagnosis of paraneoplastic dermatomyositis was made owing to progressive muscle weakness and elevation of muscle enzymes associated with the typical rash of the face and hands. He received corticosteroid therapy and then radiotherapy to the nasopharynx with good clinical outcome, disappearance of skin lesions, and recovery of muscle strength. Conclusions We report this case of dermatomyositis in early-stage nasopharyngeal carcinoma, which is a rarely described entity. Rapid treatment of dermatomyositis improved the patient’s quality of life and enabled him to support specific cancer treatments. This can be used as an element of early diagnosis and monitoring after treatment.
