Strategy and Technique of Endonasal Endoscopic Bony Decompression and Selective Tumor Removal in Symptomatic Skull Base Meningiomas of the Cavernous Sinus and Meckel's Cave.

Background: Parasellar meningiomas involving the cavernous sinus and Meckel's cave pose a management challenge because of invasion around neurovascular structures and the pituitary gland. The management options range from aggressive resection to focused radiotherapy alone. We present a strategy for these tumors that includes endonasal bony decompression, partial tumor removal, and stereotactic radiotherapy (SRT) in select cases.

Adjuvant Radiation is Associated with Improved Survival for Select Patients with Non-metastatic Adrenocortical Carcinoma.

Background: Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy for which surgery is the mainstay of treatment and for which adjuvant radiation is infrequently employed; however, small, single-institution series suggest adjuvant radiation may improve outcomes.

Methods: All patients with non-metastatic ACC treated with either surgery alone or surgery followed by adjuvant radiation were identified in the 2004-2013 National Cancer Database. Factors associated with receipt of radiation and the impact of adjuvant radiation on survival were determined by multivariable analysis.

Rheumatologic manifestations of sarcoidosis.

Sarcoidosis is a systemic, clinically heterogeneous disease characterized by the development of granulomas. Any organ system can be involved, and patients may present with any number of rheumatologic symptoms. There are no U.

Structural and Biophysical Characterization of a Cyclic Bioadhesive With Cell Attachment Ability.

Structural and cellular attachment analysis identified overall bent helical regions of adhesive peptides identified within mussel adhesive protein (MAP) capable of also attaching cells. DOPA (L-DOPA, 3,4-dihydroxyphenylalanine) is frequently identified and credited for the attachment ability of several marine proteins [Olivieri, MP, . (2002), , 149-159].

Multimarker circulating DNA assay for assessing blood of prostate cancer patients.

Background: Prostate cancer (PCa) detection using serum-based prostate specific antigen (PSA) is limited by frequent false-positive and -negative results. Genetic aberrations such as allelic imbalance (AI) and epigenetic changes such as promoter hypermethylation have been detected in circulating DNA of cancer patients. We hypothesized that circulating multimarker DNA assays detecting both genetic and epigenetic markers in serum would be useful in assessing PCa patients.

Brainstem ischemia in acute herniation syndrome.

Brain herniation from hemispheric mass lesions injures mainly the upper brainstem around the tentorial incisura. While mechanical tissue compression is usually the process of deterioration and injury, the primary injury mechanism in some patients is early brainstem ischemia from arterial compromise as demonstrated by this patient's magnetic resonance imaging (MRI) and pathology.

Transformation of a pituitary macroadenoma into to a corticotropin-secreting carcinoma over 16 years.

Objective: To describe a case of a pituitary macroadenoma that differentiated into a corticotropin (ACTH)-secreting carcinoma with metastasis to the thigh.

Methods: We present a case report with a 16-year follow-up that includes anatomic and endocrine documentation of the history of an ACTH-secreting carcinoma.

Results: A 32-year-old woman presented for evaluation in 1989 because of visual field defects.

Doxorubicin plus interleukin-2 chemoimmunotherapy against breast cancer in mice.

As recently characterized, following s.c. implantation into syngeneic C57BL/6 mice, E0771 tumor invades locally into dermal layers and peritoneum, metastasizes to the lung, and induces a nonspecific immunosuppression in the host.

A pituitary carcinoma secreting TSH and prolactin: a non-secreting adenoma gone awry.

To our knowledge, only one case of a TSH-secreting carcinoma has previously been reported. We describe here a second patient with a pituitary carcinoma producing TSH and prolactin (PRL). A 37-year-old male underwent a left frontotemporal craniotomy in 1996 for a sellar mass.

Detection of epithelial ovarian cancer using 1H-NMR-based metabonomics.

Currently available serum biomarkers are insufficiently reliable to distinguish patients with epithelial ovarian cancer (EOC) from healthy individuals. Metabonomics, the study of metabolic processes in biologic systems, is based on the use of (1)H-NMR spectroscopy and multivariate statistics for biochemical data generation and interpretation and may provide a characteristic fingerprint in disease. In an effort to examine the utility of the metabonomic approach for discriminating sera from women with EOC from healthy controls, we performed (1)H-NMR spectroscopic analysis on preoperative serum specimens obtained from 38 patients with EOC, 12 patients with benign ovarian cysts and 53 healthy women.

Treatment outcomes of three-dimensional conformal radiotherapy for localized prostate carcinoma: a large community-based experience.

Background: The current study documented the implementation of three-dimensional conformal radiotherapy and assessed the tumor control and toxicity of such treatment in a large, multisite community practice.

Methods: The authors retrospectively reviewed their first 222 consecutive patients with clinically localized (N0) prostate carcinoma treated with a 6-field conformal technique from October 1993 through March 2000. Standardized target definitions, dose planning constraints, and gantry angles were utilized to develop the treatment plan.

Recurrence of symptoms after Chiari decompression and duraplasty with nonautologous graft material.

Nonautologous material is commonly used for dural grafting. Although good results have been reported with the use of some of these materials in cranial surgery, there is a paucity of information regarding their use in craniocervical decompressive surgery. We report three cases of patients with Chiari malformation type I who experienced recurrent or new-onset Chiari symptoms after surgical decompression and duraplasty with bovine pericardium, Gore-Tex or cadaveric dura.

Synthesis, structure, and conformation of anti-tumor agents in the solid and solution states: hydroxyl derivatives of Ftorafur.

The pyrimidine antimetabolite Ftorafur [FT; 5-fluoro-1-(tetrahydro-2-furyl)uracil] has shown significant antitumor activity in several adenocarcinomas with a spectrum of activity similar to, but less toxic than, 5-fluorouracil (5-FU). It is considered as a prodrug that acts as a depot form of 5-FU, and hence the two drugs exhibit a similar spectrum of chemotherapeutic activity. Ftorafur is metabolized in animals and humans when hydroxyl groups are introduced into the tetrahydrofuran moiety.
