Content validation of an electronic remote toxicity management system in adult patients undergoing cancer treatment: a prospective longitudinal study on the QuestOnco application.

Background: Cancer-treatment toxicity is common and symptoms must be identified quickly and accurately. Since symptom reporting during consultations is hampered by time constraints and patient/oncologist biases, patient-reported outcome-measure (PROM) questionnaires are useful. A strong shift to at-home cancer treatment has led to growing interest in remote symptom monitoring via electronic-PROMs (ePROMs).

A primary small cell neuroendocrine carcinoma (SCNC) of the oral cavity (cheek mucosa): Description of a case report.

Background: Small cell neuroendocrine carcinoma (SCNC) of the oral cavity is a poorly differentiated, high-grade and very aggressive tumor with a poor prognosis.

Case Description: A 64-year-old, Caucasian, smoker man consulted for an ulcero-necrotic, exophytic, lesion of the right retromolar trigone. Haed&neck CT scan showed a right tonsillar tumor lesion.

A fatal primary gastric melanoma treated by a double immunotherapy with ipilimumab/nivolumab: description of a case report.

Background: Primary gastric melanoma (GM) is a very uncommon tumor with a poor prognosis. Until now, only a few cases have been reported in the literature.

Case Description: A 70-year-old, Caucasian, ex-smoker man, presented with asthenia, anorexia, and weight loss of 5 kg during the last 2 months.

HER2-positive metastatic, parotid salivary duct carcinoma treated with a trastuzumab/pertuzumab-based chemotherapy: A case report.

This case highlights the rare entity, salivary duct carcinoma (SDC), which is difficult to diagnose and manage. It is the first published case of a metastatic, HER2-positive parotid SDC successfully treated by a dual anti-HER2 treatment associated to a chemotherapy.

Breast and Axillary Lymph Node Metastasis from Ovarian Cancer: A Case Report.

BACKGROUND Breast metastasis (BM) is extremely rare. Ovarian cancer accounts for approximately 0.03% to 0.

Renal Metastases from a Nasal Cavity Mixed Squamous Cell and Adenoid Cystic Carcinoma: A Case Report.

BACKGROUND Adenoid cystic carcinoma (ACC) is a very rare tumor with a high risk of loco-regional recurrence and potential distant metastases. Until now, only a few cases of renal metastases from ACC have been reported in the literature. CASE REPORT A 64-year-old, Caucasian, non-smoker female, 8 months after being treated by radio-chemotherapy for a squamous cell nasal cavity tumor, presented two renal lesions associated with lung and vertebral metastases.

A paraneoplastic limbic encephalitis from an anorectal small cell neuroendocrine carcinoma: a case report.

Background: Paraneoplastic limbic encephalitis (PLE) is a rare autoimmune neurological syndrome observed in cancer patients. PLE is difficult to diagnose and presents a variable response to treatment, depending on the characteristics of the tumor and neuronal autoantibodies.

Case Presentation: A 64-year-old, Caucasian, non-smoker man presented with a rapidly developing cognitive impairment, personality change, spatial disorientation, and short-term memory loss associated with anorexia and cervical and inguinal lymph nodes.

A Spontaneous Regression of an Isolated Lymph Node Metastasis from a Primary Unknown Merkel Cell Carcinoma in a Patient with an Idiopathic Hyper-Eosinophilic Syndrome.

BACKGROUND Merkel cell carcinoma (MCC) is a rare, aggressive primary cutaneous neuroendocrine tumor frequently associated with Merkel cell polyomavirus infection. Despite its aggressiveness, a few reports of spontaneous MCC regression have been described in the literature, most of them following incisional biopsy supporting a hypothetical role of surgery-induced inflammation in the process of regression. CASE REPORT We report a case of 69-year-old Caucasian male who was followed for an idiopathic hyper-eosinophilic syndrome.

Peritoneal Myeloid Sarcoma in a Patient Treated for a Testicular Seminoma.

BACKGROUND Myeloid sarcoma is a rare extramedullary soft tissue neoplasm composed of myeloblastic cells, usually associated to hematologic tumor disorders and a poor prognosis. Its diagnosis is very difficult as radiological images are not specific. Histology and immunohistochemistry are necessary for an accurate diagnosis.

Breast metastasis from squamous cell carcinoma of the oropharynx: a case report.

Background: Breast metastases from extramammary tumors are extremely rare, the most common primary tumors being contralateral breast carcinoma, followed by lung, gynecological, gastrointestinal, melanoma, and hematological cancers. Only a few cases deriving from head and neck squamous cell carcinoma have been reported in the literature to date.

Case Presentation: We report a case of a 47-year-old Caucasian woman who presented to our hospital with a solitary breast lesion in the right upper external quadrant associated with multiple bone and visceral metastases.

Prevalence of malnutrition in patients at first medical oncology visit: the PreMiO study.

Background: In cancer patients, malnutrition is associated with treatment toxicity, complications, reduced physical functioning, and decreased survival. The Prevalence of Malnutrition in Oncology (PreMiO) study identified malnutrition or its risk among cancer patients making their first medical oncology visit. Innovatively, oncologists, not nutritionists, evaluated the nutritional status of the patients in this study.

Pituitary Metastasis from Renal Cell Carcinoma: Description of a Case Report.

BACKGROUND Pituitary metastasis is uncommon, breast and lung cancers being the most frequent primary tumors. Renal cell carcinoma (RCC) is a rare cause of pituitary metastases, with only a few cases described to date. CASE REPORT We report a case of a 61-year-old man who presented with a progressive deterioration of visual acuity and field associated with a bitemporal hemianopsia.
