Microsurgical Resection of Tumor of the Lateral Ventricle:

The surgical management of tumors of the lateral ventricles (LV) and the third ventricle (TV) remains a distinct challenge for neurosurgeons due to the deep and difficult-to-reach location and frequent involvement of adjacent critical neurovascular structures. An appropriate surgical approach should provide adequate operative working space with minimal brain retraction or brain transgression. To accomplish these goals, neurosurgeons may choose an approach that necessitates a longer distance to reach the tumor if it minimizes the amount of brain tissue that is resected or placed at risk by the approach. Furthermore, selection of the optimal approach to ventricular tumors depends on multiple other factors including the size of the ventricles and the tumor, the location of the arterial supply, pathological features of the tumor, and the surgeon’s experience. This video provides an overview of the open surgical operative corridors to the lateral tumors, highlighting the key surgical principles.

Osteogenic sarcoma of the third metacarpal displaying blastic features.

Osteogenic sarcoma is a bone cancer that primarily affects osteoblasts and occurs most often in teenagers during their growth spurt; the most common sites are the metaphyses of the thigh bone (femur), shin bone (tibia), and arm bone (humerus). Metastases occur most often in lungs; treatment consists of multidrug chemotherapy and removal of the malignant growth, or amputation of limbs.

In February 2014 Tim McGrath was diagnosed with Synovial Sarcoma after complaining of severe jaw pain. An MRI revealed an egg sized tumour however Mr McGrath turned down surgery and spent the following 18 months seeking none surgical alternatives.

“At the end of May 2015 the tumour doubled in size and I had to have a tracheotomy fitted to enable me to breathe and a feeding tube so I could eat, because the tumour had invaded the space in my mouth. Heavy doses of radiation caused the tumour to start dying and shrink and parts started to fall off, eventually I got my mouth back and I could eat very thin pieces of food.“

In October 2015, Mr McGrath was admitted to hospital where he remained for almost seven weeks following the initial 30 hour operation to remove and then reconstruct his face. 

“Before the surgery they gave me the worst case scenario, they said I would have to lose my left eye and my left ear, but I didn’t’ believe that was going to be necessary. When I woke up I was in complete shock, as well as removing part of my face and bone structure, they had removed most of the muscle in my back, they had taken a rib, and they took part of my scapula and part of my shoulder too. This was so that they could rebuild my bone structure and the surrounding area however my body rejected the first attempts. Eventually I was discharged and the cavity was closed but over time the transplant kept shrinking and I experienced numerous infections.”

During his long journey towards recovery Mr McGrath made the decision to leave his original surgeon and was welcomed with open arms by Dr Chaiyasate. "I’ve had over 20 surgeries to date and five of those have been with Dr C, none of which have been rejected.”

Dr Chaiyasate will continue with the reconstruction of Mr McGrath’s face next winter which will further help his speech and will give him the ability to eat and drink again.

Blood Test spots Cancer a year early using ctDNA analysis:
Researchers have taken an important step toward better lung cancer treatment by using blood tests to track genetic changes in tumors as they progress from their very earliest stages.
With experimental tests that detect bits of DNA that tumors shed into the blood, they were able to detect some recurrences of cancer up to a year before imaging scans could, giving a chance to try new therapy sooner.
It’s the latest development for tests called liquid biopsies, which analyze cancer using blood rather than tissue samples. Some doctors use these tests now to guide care for patients with advanced cancers, mostly in research settings. The new work is the first time tests like this have been used to monitor the evolution of lung tumors at an early stage, when there’s a much better chance of cure.

A massive brain tumor with what appeared to be adult teeth embedded in it which was found in the brain of a four month old infant. An MRI was ordered to investigate why the infant’s head was rapidly outgrowing its body and extremities. What they found was a so called craniopharngioma, a benign type that can grow to the size of a golf ball. This is the first time in recorded history that not only were human teeth found in a craniopharngioma, but also that the teeth were fully grown adult teeth.

¿Es lo mismo tumor y cáncer?

Un cáncer es un tumor, pero no todos los tumores son cánceres…

Se llama tumor a toda estructura formada por el aumento de tamaño de un tejido a consecuencia de la reproducción incontrolada de un conjunto de células del mismo.

Se dice que un tumor es benigno cuando las células que lo forman permanecen unidas, formando una masa compacta que frecuentemente incluso se encuentra rodeada por una membrana de contención.

El cáncer o tumor maligno, por el contrario…

These are photographies of teratoma tumors. A teratoma is a tumor containing a variety of different cells, caused by the tumor replicating cells of the human body it “naturally” should not. The teratoma is often congenital, but may not show signs of existence until later in life. Teratomas are known to contain teeth and hair (as in the pictures), bone, and in uniquely rare cases, more complex parts such as eyes, hands, and feet.
