Altered splicing machinery in lung carcinoids unveils NOVA1, PRPF8 and SRSF10 as novel candidates to understand tumor biology and expand biomarker discovery.

Background: Lung neuroendocrine neoplasms (LungNENs) comprise a heterogeneous group of tumors ranging from indolent lesions with good prognosis to highly aggressive cancers. Carcinoids are the rarest LungNENs, display low to intermediate malignancy and may be surgically managed, but show resistance to radiotherapy/chemotherapy in case of metastasis. Molecular profiling is providing new information to understand lung carcinoids, but its clinical value is still limited.

The Role of Intraperitoneal Intraoperative Chemotherapy with Paclitaxel in the Surgical Treatment of Peritoneal Carcinomatosis from Ovarian Cancer-Hyperthermia versus Normothermia: A Randomized Controlled Trial.

Background: The treatment of ovarian carcinomatosis with cytoreductive surgery and HIPEC is still controversial. The effect and pharmacokinetics of the chemotherapeutics used (especially taxanes) are currently under consideration.

Methods: A phase II, simple blind and randomized controlled trial (NTC02739698) was performed.

Prognosis and survival of patients diagnosed with well-differentiated and dedifferentiated retroperitoneal liposarcoma.

Objectives: The main objective is to establish the overall survival and disease-free survival profiles regarding the patients with retroperitoneal liposarcoma, making a comparison based on the well-differentiated and dedifferentiated histological subtypes. The secondary objectives are to descriptively analyze the clinical characteristics of said patients and to identify and analyze other independent variables that might modify these survival profiles significantly.

Methods: An observational and analytical study was performed using a retrospective historical cohort that was followed prospectively.

Surgical treatment of vena cava leiomyosarcomas: Series of cases in a referral center and literature review.

Background: Primary tumors of the inferior vena cava are rare tumors of mesenchymal origin. They arise from the smooth muscles of the vena cava wall. Due to its low prevalence, there are few definitive data on its treatment and prognosis.

Epithelioid angiomyolipoma presenting as an urothelial.

Objective: Renal angiomyolipoma is a mesenchymal neoplasm composed of dysmorphic blood vessels, smooth muscle, and adipose tissue. Epithelioidangiomyolipoma is an uncommon variant considered potentially malignant. We report a case of renal epithelioid angiomyolipoma suspicious for urothelialcarcinoma of renal pelvis.
