With the use of cis-diamminedichloroplatinum(II), cisplatin, to enhance the effect of radiation a combined modality approach was designed to treat patients with inoperable, locally advanced NSCLC. The regimen consisted of radiation doses of 300 cGy for 4 days every week for 4 weeks with a 2 week split in between. Each radiation dose was followed by an i.v. injection of cisplatin 6 mg/m2 within 30 min. Hydration consisted on an oral fluid intake of 2 L only, enabling the patient to receive the treatment on an outpatient basis. Of 40 patients entered into the study, 37 were evaluable for toxicity and 33 for response. Overall response rate was 65% and complete response rate 22%. Median duration of local control was 7 months. The majority of all patients (76%) eventually progressed at the primary tumor site, while in 16 patients relapse occurred in distant sites first. Median duration of overall survival was 10.5 months, whereas that of complete responders was 29.5 months. Generally, acute side effects were transient and did not require discontinuation of treatment. One patient presented with thrombocytopenia 4 weeks after treatment had been finished. His death of cerebral bleeding was likely to be related with his therapy-resistant malignancy. Of late side effects three patients showed disabling symptoms consisting of uncontrollable pulmonary infections in the presence of tumor in two patients, one patient had radiation myelopathy and another experienced vertebral collapse with distal paresis. The combination of radiation and daily low-dose cisplatin is a tolerable treatment modality with most benefit for patients reaching a complete remission. Intensification of the regimen is being planned in those patients with inoperable, locally advanced squamous cell lung cancer to reach a complete remission.

The aim of this article was to describe rarely occurred carcinoma adenoides cysticum located in the larynx, trachea and thyroid. Epidemiology, clinical course and medical therapy was demonstrated. In reported case concerning 65-year old woman early bilateral paresis of vocal folds was observed as results of the perineural infiltration. That caused sudden laryngeal dyspnea. It is important to pay attention on local extensiveness of neoplasm. Besides changes in larynx, neoplastic infiltration was found in trachea, preesophageal tissues and right lobe of thyroid. For above reasons there is no possible to exclude thyroid as a primary tumor of carcinoma adenoides cysticum.

An 8-year-old male Belgian Malinois was referred for evaluation of progressive caudal paresis of 2 to 3 weeks' duration. Radiography revealed a mottled appearance to the body of L4 and misshapen intervertebral foramen at L4-L5. Myelography revealed that the dye column terminated within the body of L4. Computed tomography revealed a soft tissue mass adjacent to or involving the spinal cord and L4, with complete destruction of a portion of the floor of the vertebral foramen. Small circular lesions were also noticed within the body of L3 and L5. A left-sided hemilaminectomy was performed. Histologic examination of a biopsy specimen revealed a high-grade sarcoma. Because of the poor prognosis, the dog was euthanatized. Necropsy examination revealed osteosarcoma, with lesions in L3 to L7, the sacrum, and the lungs. Metastatic lesions in adjacent bones have been termed skip metastases and the primary tumor is typically in long bones. Prognosis associated with skip metastases is similar to or even graver than that associated with pulmonary metastases. In the dog of the present report, the unusual finding of distinct foci of osteosarcoma within 5 adjacent lumbar vertebrae and the sacrum was consistent with skip metastases, potentially spread via the vertebral venous plexus.

A 67-year-old man presented with left lower cranial nerve paresis and dysfunction of the left cerebellar hemisphere 4 years after amputation of the left lower leg because of clear cell chondrosarcoma (CCC). Neuroimaging studies showed an osteolytic extradural mass with homogeneous enhancement in the left posterior fossa. Bone scintigraphy disclosed a single high-uptake lesion at the same site. The tumor was removed totally via a left suboccipital craniotomy. Histological examination found mainly clear cells arranged in a microlobular pattern separated by thin fibrovascular stroma. The nuclei were regular with few mitotic figures. Immunohistochemical staining showed the tumor cells reacted intensely for both S-100 protein and vimentin. Osteoclast-like multinucleated giant cells were found at the periphery of the lobules. The primary tumor showed the same findings and the metastatic tumor manifested no malignant change. The histological diagnosis was metastatic CCC. CCC is a very rare neoplasm with slow growth and low-grade malignancy. Distant metastasis is rare but can occur in the skull base bone despite radical resection of the primary tumor. Osteolytic findings of homogeneous enhancement on magnetic resonance imaging and a high uptake on bone scintigraphy are indicative of metastatic tumor from previous CCC.

Nasopharyngeal carcinoma (NPC) is a tumor arising from the epithelial cells that cover the surface and line the nasopharynx. The annual incidence of NPC in the UK is 0.3 per million at age 0-14 years, and 1 to 2 per million at age 15-19 years. Incidence is higher in the Chinese and Tunisian populations. Although rare, NPC accounts for about one third of childhood nasopharyngeal neoplasms. Three subtypes of NPC are recognized in the World Health Organization (WHO) classification: 1) squamous cell carcinoma, typically found in the older adult population; 2) non-keratinizing carcinoma; 3) undifferentiated carcinoma. The tumor can extend within or out of the nasopharynx to the other lateral wall and/or posterosuperiorly to the base of the skull or the palate, nasal cavity or oropharynx. It then typically metastases to cervical lymph nodes. Cervical lymphadenopathy is the initial presentation in many patients, and the diagnosis of NPC is often made by lymph node biopsy. Symptoms related to the primary tumor include trismus, pain, otitis media, nasal regurgitation due to paresis of the soft palate, hearing loss and cranial nerve palsies. Larger growths may produce nasal obstruction or bleeding and a "nasal twang". Etiological factors include Epstein-Barr virus (EBV), genetic susceptibility and consumption of food with possible carcinogens--volatile nitrosamines. The recommended treatment schedule consists of three courses of neoadjuvant chemotherapy, irradiation, and adjuvant interferon (IFN)-beta therapy.

Epithelial tumors of the parotid gland comprise 3% of head and neck tumors, and 70%-80% of those are benign. Pleomorphic adenoma is the most common tumor of the parotid gland. Recurrence rate of pleomorphic adenomas (RPAs) following superficial parotidectomy was reported to be as high as 4%, sometimes associated with inadequate surgical treatment of the primary tumor. These tumors have a very slow growth rate, and a ten-year follow-up period is mandatory. RPAs are usually located in the superficial lobe (75%) and are often multinodular. Treatment of RPAs is challenging due to a high risk of facial nerve paresis (7%-50%) and of re-recurrence. Occasionally, post-operative radiotherapy is indicated, but this treatment must be balanced with potential long term risks of secondary malignancy. Medical records of 16 patients with first recurrence and 4 patients with more than one recurrence who were treated in our institution during the past 5 years were reviewed. Five patients were treated by post-operative radiotherapy. Residual or recurrence rate following a second procedure was 15%. Two patients (10%) had permanent paresis of a single branch of the facial nerve. Seventeen out of 20 patients (85%) treated were disease-free after a follow-up period of 5 years. In conclusion, surgical treatment of RPAs is a complex procedure which should be managed by a trained surgical team and can be performed with success and minimal morbidity.

A 10-yr-old male intact Asian small clawed otter (Aonyx cinerus) was presumptively diagnosed by histopathology and immunohistochemistry with lymphangiosarcoma after bony destruction of the ischium and spinal column from local tumor invasion had caused progressive signs of hind limb lameness and paresis/paralysis, which led to humane euthanasia. At necropsy, the primary tumor was identified as a flocculent mass present under the caudal lumbar vertebrae. Multiple nerves were seen to run from the spinal cord into the wall of the mass. This mass had locally invaded the surrounding muscle, vertebral column, and spinal cord, which led to the clinical signs noted at presentation. Bony destruction was severe with almost complete obliteration of the right ischium and osteolysis of L6, exposing the spinal cord beneath. The tumor had metastasized to at least two different sites within the spleen. The abdominal tumor was confirmed to be of endothelial origin by the use of immunohistochemical staining for factor VIII-related antigen and was confirmed as lymphatic origin versus vascular origin because of the lack of red blood cells within the vessels. The length of time from initial presentation with hind limb lameness to euthanasia because of hind limb paralysis was 4 mo. This is the first report of lymphangiosarcoma, an uncommon malignant neoplasm of lymphatic origin, in a mustelid and the first report of neoplastic disease in an Asian small clawed otter. In addition, the presentation of hind limb paresis associated with bony lysis because of local tumor invasion has not been previously reported with lymphangiosarcoma in humans, domestic animals, or nondomestic animals.

Spinal subarachnoid spread is not uncommon in brain oligodendrogliomas; on the other hand, symptomatic involvement of the spinal cord and cauda is very rare, with only 16 reported cases. We report the case of a 41-year-old man who underwent resection of a low-grade frontal oligodendroglioma 4 years previously. He was again observed because of bilateral sciatic pain followed by left leg paresis. A spine MRI showed an intramedullary T12-L1 tumor with root enhancement. At operation, an intramedullary anaplastic oligodendroglioma with left exophytic component was found and partially resected. Two weeks later, a large left frontoparietal anaplastic oligodendroglioma was diagnosed and completely resected. The patient was neurologically stable for 8 months and died 1 year after the spinal surgery because of diffuse brain and spinal leptomeningeal spread. The review of the reported cases shows that spinal symptomatic metastases can occur in both low-grade and anaplastic oligodendrogliomas, even many years after surgery of the primary tumor; however, they exceptionally occur as first clinical manifestation or as anaplastic progression. The spinal seeding represents a negative event leading to a short survival.

Hemangioma is the most common primary tumor of the spine. Pregnancy is a risk factor increasing the possibility of disclosure or exacerbation of symptoms of spinal hemangioma. This paper presents a case of 32-year-old woman with hemangioma of Th6 vertebrae, which was revealed by paresis of the lower limbs and sphincters dysfunction at 34 weeks gestation. Pregnancy has ended with a cesarean section. Then posterolateral thoracotomy and removal of hemangioma were performed. Spinal cord was decompressed and stabilization of the spine with metal implants was carried out. Histological examination discovered cavernous hemangioma weaving. The patient is followed up in the outpatient clinic. Despite the improvement of neurological status--enhancement of the sensory function and development of bladder and rectal sphincter automatism--she did not regain the ability to walk alone.

A 36-year-old Indian man, a recently diagnosed case of the right lung carcinoma underwent fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) for staging of the malignancy. PET/CT showed increased FDG uptake in the right lung mass, consistent with the known primary tumor. Right hemidiaphragm was found to be elevated on CT, suggesting right diaphragmatic paresis. The PET scan demonstrated asymmetric, intense FDG uptake in the left hemidiaphragm and accessory muscles of respiration, which was possibly due to compensatory increased workload related to contralateral right diaphragmatic paresis. The right diaphragmatic paresis was hypothesized to be caused by phrenic nerve palsy by right lung neoplasm.
