[Treatment of early glottic carcinoma with transoral laser CO2].

OBJECTIVE: We present our outcome in the treatment of 125 patients with malignant glottic lesions between 1992 and 2003 in a retrospective study. PATIENT AND METHODS: We analyze 125 cases of patients, with previously untreated carcinoma of the larynx with histological diagnosis, treated with Transoral Laser Microresection. We will pay special attention to those tumors involving the Anterior Commissure. We will also analyze several parameters related to the post and intraoperatory histopathological report, in order to decide adjuvant therapies. We will also analyze the technique indications, complications, hospital length of stay, oncologic and functional outcomes, survival and follow up of recurrences. OUTCOMES AND CONCLUSION: Transoral laser microresection is an effective and functional preserving procedure, and nowadays the base of the treatment of early glottic carcinoma. Anterior Commissure involvement is a prognostic factor. Sometimes complementary therapies are needed based on by the histopathological report.

[Comparison between 18F-FDG PET and conventional imaging techniques (CT SCAN and MRI) in the diagnosis of head and neck tumor suspicion of recurrence].

BACKGROUND: This study aimed to assess the results obtained with the positron emission tomography (PET) and conventional anatomic imaging methods (CT scan and MRI) in the diagnosis of suspicion of tumor recurrence in head and neck cancers. METHODS: Thirty patients with suspicion of tumor recurrence due to head and neck cancers were reviewed retrospectively. Consequently, 34 PET studies were performed. The images were obtained in the PET Institute of Madrid. They were interpreted by visual and semiquantitative analysis. The results were confirmed with clinical follow-up, response to treatment or with histological studies in some cases. RESULTS: Sensitivity and specificity of the PET were 95.6% and 81.8% respectively, while it was 65% and 80% for the CT scan/MRI. CONCLUSIONS: We can conclude that PET provides better results than conventional imaging techniques in the detection of head and neck cancer recurrence.

[Impact of FDG-PET in therapeutic management of patients with suspected recurrence of head and neck cancer].

OBJECTIVE: This study aims to evaluate the impact of Positron Emission Tomography on therapeutic decisions in patients with suspicion of recurrence of head and neck cancers. MATERIAL AND METHODS: The diagnostic and therapeutic impact of FDG-PET was evaluated in 59 of 60 studies performed in a sample of 54 patients. The impact was graded on five levels (high, moderate, low, no impact and negative impact) following the Hicks et al. classification modified by us. RESULTS: The FDG-PET impact was high in 28 studies (47.46 %), moderate in 7 (11.86 %), low in 20 (33.90 %), no impact in 3 (5.09 %) and finally negative impact in 1 study (1.69 %). CONCLUSIONS: FDG-PET is useful in the management of patients in 59.32 % of the studies with indeterminate physical examination and conventional imaging tests. This paper supplies new data since we did not find any studies showing statistical results on therapeutic impact of FDG-PET in head and neck cancers in a systematic review of the literature made by our group.

[Primitive neuroectodermal tumor/extraosseus Ewing sarcoma of the temporal bone].

The term primitive neuroectodermal tumor (PNET) should be included in the differential diagnosis of small round blue cell tumors, which come from the neural crest and explain their neuroectodermal character. This is one of the most indifferentiated histological types of malignant tumors. In the PNET family, we high light the Ewing's Sarcoma, that is frecuently located in bony sites and has a less frequent localization in soft tissues. We focus on one atypic case of PNET/Extraosseus Ewing's Sarcoma that involves the external auditory canal and infiltrates the temporal bone. Surgery followed by postoperative chemotherapy and radiation offers the best local control of the disease.

[Cancer of the parotid gland].

OBJECTIVE: To review our experience and results in the diagnosis and treatment of a low incidence pathology such as the cancer of the parotid gland. METHODS: The study reviewed 40 patients with malignant tumors of the parotid gland treated between 1991 and 2002 in our hospital. It was used the staging system TNM (American Joint Committee on Cancer 1997). RESULTS: The most common histological type in our series is the squamous cell carcinoma, in general unilateral and in the superficial lobe. Rapid tumor enlargement, fixation to the skin, cervical lymphadenopathy, pain and facial palsy are malignancy clinical findings. We obtained a 56% 5-year global survival rate, with a 68% for stages I and II, and 43% for stages III and IV. CONCLUSIONS: This pathology has a low incidence but high mortality. The staging and histological type are important prognostic factors. The surgery is the election treatment, associated with neck disection or radiotherapy.

[Geniculate ganglion tumors. Therapeutic and reconstructive management].

We present five cases of patients diagnosed of a facial nerve tumoral lesion localised at the Geniculate Ganglion and all of which underwent surgical resection. The initial symptoms were in four cases of peripheral facial nerve paralysis and in the fifth case facial paresis. Two trans-mastoid extralabyrinthine approaches were performed and one through a combined path (middle fossa and trans-mastoid) with reconstruction of the facial nerve through a termino-terminal graft. In the fourth case, an approach through fossa media was done, and did not include nerve reconstruction but palliative treatment with a palpebral gold plaque. In the fifth case, a modified trans-labyrinthine approach with facial-hypoglossus termino-terminal anastomosis. Histological diagnosis was 3 neurinomas and 2 hemangiomas. Of the termino-terminal grafts two managed a functional Grade III of the House-Brackmann classification. The third one sustained a Grade VI and therefore a suspension with temporal muscle was carried out. The patient with facial-hypoglossus anastomosis is in a functional Grade IV. Geniculate ganglion tumors are in their majority benign and their treatment is the total resection of the tumor. Nerve reconstruction can be primary or deferred with the aid of a nerve graft or anastomosis, being necessary palliative techniques when resection is not possible.

[Idiopathic recurrent facial palsy].

We report a 34 year old female patient with six episodes of idiopathic right facial palsy, all of wich had total recovery. Idiopathic recurrent facial palsy is a rare entity, with a few cases in the literature. Recurrent facial palsy is usually in the setting of a family history and have both autosomal dominant and recessive inheritance or in the setting of hypertension and diabetes. A review of the literature does not report a previous case with six episodes.

[Temporal bone chondroblastoma. A clinical case and literature review].

We report a clinical case of a 31 year old male with a left temporal painful mass of six months evolution. After radiologic diagnosis, intraoperatory biopsy and surgical removal, the anatomopathological result confirmed the histology of chondroblatoma, with a satisfactory postoperative evolution. The chondroblastoma is a benign bone tumor typically located in the epiphysis of long bones and the temporal bone is an excepcional location as we have verified through a literature review.

[Middle ear tumor of neuroendocrine nature].

Middle ear neuroendocrine neoplasms are rare and of benign behaviour. Diagnosis is difficult since they produce non-specific symptoms. Electron microscopy and immunochemistry are necessary. We present a carcinoid tumor in a 28-year-old man with one side deafness. He underwent tympanoplasty, staying free of recurrences two years and a half later.

[Granulocytic sarcoma. A case with an unusual location].

An unusual case of granulocytic sarcoma infiltrating the parotid gland of a 17-year-old woman is reported. There was no evidence of acute myeloid leukemia or chronic myeloproliferative disease at time of diagnosis. The myeloid nature of the tumor was discovered with the aid of immunochemistry. The patient responded well to combined polychemotherapy and local radiotherapy. Eighteen months after diagnosis, the bone-marrow biopsy showed no signs of blast infiltration. Granulocytic sarcoma should be considered in the differential diagnosis of malignant tumors of the parotid gland, although it is rare.
