Pure small cell neuroendocrine carcinoma of urinary bladder: A case report.

Small cell neuroendocrine carcinoma of the bladder is rare. We report a case of small cell carcinoma of the bladder with extensive regional lymph node metastases who underwent radical cystoprostatectomy and subsequent adjuvant systemic chemotherapy and chemoradiotherapy.

Endometrial adenocarcinoma with bone metastasis: A case report.

We reported a female with endometrial adenocarcinoma who was evaluated with whole-body bone scan for new-onset bone pains 6 months after completion of treatment.

Clinical Characteristics and Outcomes of COVID-19 in 1294 New Cancer Patients: Single-Center, Prospective Cohort Study from Iran.

OBJECTIVE: To determine the clinical characteristics and outcomes of COVID-19 in a large cohort of new cancer patients referred to an oncology clinic in the north of Iran. METHODS: During the 20-month COVID-19 pandemic, new cancer patients were followed-up. Demographic, pathologic, and clinical variables were collected for each patient. COVID-19 was confirmed based on a positive polymerase chain reaction test. Analyses were performed using the STATA version 14.0 at a significance level of 0.05. RESULTS: In this study, 1294 new cancer patients were followed for 24 months (mean age: 58.7 years [range 10-95]). During the study period, COVID-19 was diagnosed in 9.4% of the patients with hospitalization rate of 3.4%, an ICU admission rate of 0.7%, and COVID-19 mortality rate of 4.9%. Hematological malignancies (ORU= 2.6, CI95% 1.28-5.34), receiving palliative treatments (ORA=3.03, CI95% 1.6-5.45) and receiving radiotherapy (ORA=2.07, 1.17-3.65) were the most common predictive factors of COVID infection in cancer patients. Also, the COVID mortality was higher in brain cancer patients (p = 0.07), metastatic disease (p = 0.01) and patients receiving palliative treatments (p = 0.02). CONCLUSION: In patients suffering from cancer, COVID-19 infection can be predicted by cancer type, palliative care, and radiotherapy in cancer patients. Furthermore, brain cancers, metastasis, and palliative care were all associated with COVID-19-related mortality.

Axillary lymph-node metastases as the primary presentation of high-grade serous ovarian carcinoma: A case report.

We reported a female presented with an initial diagnosis of metastatic axillary lymph-node carcinoma that comprehensive assessments revealed a definitive diagnosis of high-grade serous ovarian carcinoma as the primary tumor.

A case report of prostate adenocarcinoma with leptomeningeal carcinomatosis and intracerebral metastasis.

Despite the fact that prostate cancer is the most prevalent cancer in men, metastases to the central nervous system including leptomeningeal involvement by prostate carcinoma is a rare event. The prognosis of metastatic prostate cancer is very poor due to lack of CNS penetrating therapeutic agents.

A case report of endometrial adenocarcinoma with leptomeningeal metastases.

In patients with a history of solid tumors, any new onset of neurological symptoms should be assessed for central nervous system involvement even in rare cases such as gynecological malignancies that nervous system involvement is a rare event.

A case report of mediastinal cavernous hemangioma.

When faced with a hypervascular mediastinal tumor, mediastinal hemangioma should be taken into consideration. Although it is uncommon, considering this important diagnosis may avoid a possible extensive surgery that is not necessary.
