BACKGROUND Facial pain and numbness are common symptoms with a variety of causes; rarely, it is an initial sign of perineural infiltration of malignant tumors. CASE REPORT Here, we report 3 challenging cases, all presenting with pain and numbness of the cheek as the primary symptoms. Upon referral, there were neither signs of severe illness nor information about previous malignant diseases, while the diagnostic work-ups revealed additional involvement of the facial nerve in 2 of the cases. Surgical removal of the perineural tissue around the infraorbital nerve revealed perineural invasion by a squamous carcinoma...

NUMB, and its close homologue NUMBL, behave as tumor suppressor genes by regulating the Notch pathway. The downregulation of these genes in tumors is common, allowing aberrant Notch pathway activation and tumor progression. However, some known differences between NUMB and NUMBL have raised unanswered questions regarding the redundancy and/or combined regulation of the Notch pathway by these genes during the tumorigenic process. We have found that NUMB and NUMBL exhibit mutual exclusivity in human tumors, suggesting that the associated tumor suppressor role is regulated by only one of the two proteins in a specific cell, avoiding duplicate signaling and simplifying the regulatory network...

In the absence of significant extracranial disease, patients with solitary brain metastases have shown benefit with resection. Brain lesions due to endometrial cancer are uncommon, and the only described skull base involvement is limited to the pituitary gland. We report the case of a 60-year-old female with endometrial cancer who presented with weeks of right cheek pain and numbness that was accompanied by headaches. We describe the magnetic resonance imaging (MRI) findings and surgical resection of a solitary endometrial metastasis involving the infratemporal fossa, middle fossa, cavernous sinus, trigeminal nerve, and nasal sinuses...

BACKGROUND: Oligodendrogliomas constitute 5% of all primary brain tumors and are the third most common cancer among intracranial tumors. More than 90% of oligodendrogliomas have supratentorial localization. Oligodendrogliomas arising in cerebellar peduncle are substantially rare even less than 1%. Up to now, six oligodendroglioma cases with cerebellar peduncle localization have been presented. We aimed to discuss our WHO grade II oligodendroglioma case which originated from cerebellar peduncle in the light of literature...

Importance: Making a good decision about breast reconstruction requires predicting how one would feel after the procedure, but people tend to overestimate the impact of events on future well-being. Objective: To assess how well patients predict future well-being after mastectomy, with or without immediate reconstruction, with the following a priori hypotheses: Patients will overestimate the negative impact of mastectomy and positive impact of reconstruction, and prediction accuracy will be associated with decision satisfaction and decision regret...

BACKGROUND: Chemotherapy may induce peripheral neuropathy, which often results in the chemotherapy dose being reduced or the chemotherapy regimen being stopped. At present, there are no treatment guidelines for chemotherapy-induced peripheral neuropathy. Glutamine is one of the treatment strategies currently applied in practice. This strategy is expensive and lacks clear evidence as to its efficacy. PURPOSE: To evaluate the effect of oral glutamine on CIPN in cancer patients...

Interleukin-8 (IL-8) serves an important function in chronic inflammation and cancer development; however, the underlying molecular mechanism(s) of IL-8 in uterine cervical cancer remains unclear. The present study investigated whether IL-8 and its receptors [IL-8 receptor (IL-8R)A and IL-8RB] contributed to the proliferative and migratory abilities of HeLa cervical cancer cells, and also investigated the potential underlying molecular mechanisms. Results demonstrated that IL-8 and its receptors were detected in HeLa cells, and levels of IL-8RA were significantly increased compared with those of IL-8RB...

RATIONALE: Superior vena cava syndrome (SVCS) is the obstruction of blood flow through the SVC, causing complete or partial blockade of the collateral circulation of returning venous blood. SVCS is frequently presented with facial, neck, trunk, and upper limbs swelling and so on. However, to the best of our knowledge, the obstruction of the venous return in the spinal veins is rarely a manifestation of SVCS. PATIENT CONCERNS: We presented a rare case of a 52-year-old male patient with 2-month history of progressive right upper limb numbness and swelling and 10-day history of extremities malfunctioning...

RATIONALE: Inverted papilloma (IP) is a benign tumor that should be monitored carefully because it frequently recurs and has the potential to become malignant. PATIENT CONCERNS: We report a case of a 59-year-old woman who presented with a mass which had been found incidentally on positron emission tomography computed tomography (PET CT). DIAGNOSES: Using endoscopy and CT, the preoperative diagnosis was inverted papilloma. PET CT showed a mass with hot uptake in the left ethmoid and frontal sinus (maximum standardized uptake value (SUVmax) = 7...

Although numerous pathways are known to control the tumor suppressor protein p53, coordinated regulation of the p53-Notch axis by Numb may have an even more remarkable impact. In this issue, Colaluca at al. (2018. J. Cell Biol. reveal an unexpected role of a newly characterized Numb splice variant in the regulation of p53, which may have significant implications for therapeutic intervention in breast cancer.

Asymmetric cell division results in two distinctly fated daughter cells. A molecular hallmark of asymmetric division is the unequal partitioning of cell fate determinants. We have previously established that growth factor signaling promotes protein depalmitoylation to foster polarized protein localization, which, in turn, drives migration and metastasis. We report protein palmitoylation as a key mechanism for the asymmetric partitioning of the cell fate determinants Numb and β-catenin through the activity of the depalmitoylating enzyme APT1...

RNA-binding protein Musashi-2 (MSI2) is a key regulator in stem cells, it is over-expressed in a variety of cancers and its higher expression is associated with poor prognosis. Like Musashi-1, it contains two N-terminal RRMs (RNA-recognition Motifs, also called RBDs (RNA-binding Domains)), RRM1 and RRM2, which mediate the binding to their target mRNAs. Previous studies have obtained the three-dimensional structures of the RBDs of Musashi-1 and the RBD1:RNA complex. Here we show the binding of MSI2-RRM1 to a 15nt Numb RNA in Fluorescence Polarization assay and time resolved Fluorescence Resonance Energy Transfer assay...

Docetaxel constitutes a widely used chemotherapeutic agent as a first-line treatment for several neoplastic diseases. One of the most common side effects induced by this drug is polyneuropathy, which among other symptoms can cause gait disbalance. However, in exceptional cases gait disturbances could be related to docetaxel-induced hydrocephalus, a rare event that up to the present has been overseen throughout the medical literature and should be meticulously differentiated from polyneuropathy, since its clinical features, treatment, and prognosis differ drastically...

We evaluated the feasibility of maintenance treatment using UFT (a combination of tegafur and uracil) after adjuvant platinum-based chemotherapy in patients with resected lung cancer. A prospective feasibility trial was conducted. Between 2010 and 2014, UFT was administered for 2 years sequentially after platinum-based adjuvant chemotherapy in 24 patients with resected Stage IIA-IIIA non-small cell lung cancer. The safety of UFT and the rate of treatment completion were then evaluated. The prior platinum-based chemotherapy regimens consisted of cisplatin+vinorelbine in 16 patients, carboplatin+paclitaxel in 5 and carboplatin+S-1 in one...

PURPOSE: Over half of all cancer patients receiving taxane-, platinum-, or vinca alkaloid-based chemotherapy experience chemotherapy-induced peripheral neuropathy (CIPN), which includes numbness, tingling, pain, cold sensitivity, and motor impairment in the hands and feet. CIPN is a dose-limiting toxicity, potentially increasing mortality. There are no FDA-approved drugs to treat CIPN, and behavioral interventions such as exercise are promising yet understudied. This secondary analysis of our nationwide phase III randomized controlled trial of exercise for fatigue examines (1) effects of exercise on CIPN symptoms, (2) factors that predict CIPN symptoms, and (3) factors that moderate effects of exercise on CIPN symptoms...
