52-year-old male was diagnosed in 2004 with a carcinoma of the lower rectum and underwent surgical anterior resection of the rectal tumor which was a well differentiated adenocarcinoma. In 2008 he underwent emergency operation for a perforated pyloric ulcer and then a radical resection of a gastric tumor which infiltrated the entire thickness of the gastric wall. It was a G3 diffuse type adenocarcinoma with signet ring cells, at pT3N2 stage.
70-year-old-male was diagnosed with colon cancer. After undergoing a right hemicolectomy, hepatic lesions were revealed. Three months after starting chemotherapy a CT revealed recurrent hepatic disease and celiac lymphadenopathy. He underwent directed therapy with radiofrequency ablation and stereotactic radiation, but unfortunately a repeat CT showed progressive disease in the liver and new pulmonary disease. Upon surgical exploration, his liver disease was deemed too extensive for surgical resection.
7-year-old boy was diagnosed with diffused intra-axial brainstem expansive lesion. The spine MRI scan indicates spread of the patient's tumor down along the spinal cord, in spite of having reduced at the brainstem. The expert agrees that radiation to the spine that the child started receiving is appropriate, and recommends that the child resume chemotherapy to cover the tumor more globally.
A 72 years old female that 8 years ago was diagnosed with adenocarcinoma of the sigma with liver metastasis.
65-year-old male experienced loss of consciousness, and a CT scan showed a left temporal mass which was confirmed by MRI. The patient underwent Stereotacti biopsy of mass, and Histological examination gave a diagnosis of anaplastic astrocytoma. He started chemoradiation with fotemustine (nitrosourea alkylating agent). Repeated MRI showed progression with mass effect, mild uncal herniation and enlarging ventricles. He has stable expressive aphasia and hemisyndrome, lethargy and decreased motivation. His treatment was switched from phenobarbital to levetiracetam.
36-year-old otherwise healthy female presented with an atypical pap smear. Biopsy of cervix revealed poorly Differentiated Neuroendocrine Carcinoma. Immunohistochemical staining showed the cells positive for NSE, SYN, CHR, and 90% positive for Ki67 (proliferative index). The findings of the PET-FDG test showed pathological absorption of FDG as a primary tumor of the cervix, towards the left side of the body. Moreover, evidence is seen of nodal metastatic spread in the retroperitoneum and pelvis, mainly on the left.
55-year-old female was diagnosed with glioblastoma after suffering increasing headaches, and was treated with radiation with concurrent Temodal. MRI exam that was performed after 2 additional cycles of CCNU showed tumor progression. The expert recommends different further treatment options.
7-year-old boy with prodrome of right-sided and right face weakness, gait ataxia, and intermittent headaches. Head computed tomography demonstrated a tumor at the brainstem/posterior fossa, and then MRI confirmed a diffuse intrinsic pontine glioma (a typical brainstem glioma). Following initiation of dexamethasone (Decadron, steroid for vasogenic edema), the child has started experimental treatment with the medicine nimotuzumab to be followed with conventional radiotherapy.
