Treatment and prognostic factors of papillary thyroid microcarcinoma.

OBJECTIVE: To discuss the prognostic factors and outcomes of treatment in patients diagnosed with papillary thyroid microcarcinoma. DESIGN: Retrospective observational case review. SETTING: Department of Otorhinolaryngology of the tertiary referral teaching hospital of Parma. PARTICIPANTS: Ninety-seven patients diagnosed with PTMC and surgically treated between January 1998 and December 2007. MAIN OUTCOME MEASURES: Clinical and histopathological characteristics of the study group were identified and statistically analysed. RESULTS: No cancer-related deaths were registered. Incidence of recurrent disease was 9% after a 43 month mean follow-up (range 12-120). Univariate analysis detected that metastases in neck lymph nodes at diagnosis (p = 0.025), a tumour >5 mm in size (p = 0.011), the presence of bilateral tumoural foci (p = 0.007), the presence of capsular invasion (p = 0.001), and the presence of vascular invasion (p = 0.004) were related to recurrent disease. On multivariate analysis, the presence of bilateral tumoural foci (p = 0.030), and the presence of capsular invasion (p = 0.005) were significantly related to tumour recurrence. CONCLUSION: The prognosis for patients with papillary thyroid microcarcinoma in this series was excellent, with a 100% survival rate and minimal surgical-related morbidity. Nevertheless, approximately 10% of patients developed recurrent disease; aggressive treatment may be justified depending on the presence or absence of prognostic risk factors.

The role of surgery in children with head and neck rhabdomyosarcoma and Ewing's sarcoma.

Rhabdomyosarcoma and Ewing's sarcoma are relatively common malignant tumours in paediatric population. In the past, surgery was the mainstay of treatment and survival rates were poor. Afterwards, the development of multi-agent chemotherapy protocols during the past four decades resulted in a dramatic improvement in long-term survival. As a consequence, the significance of surgery has been the subject of critical discussion in the literature. Nowadays the standard treatment of rhabdomyosarcoma and Ewing's sarcoma consists in a multimodal therapy involving chemotherapy, radiotherapy and surgery. Nevertheless, the role of surgery still remains controversial. In particular, the cure of head and neck localizations presents debatable aspects since defined criteria to establish the risks and the benefits of surgical treatment do not exist at this time. This article reviews the role of surgery in children with head and neck rhabdomyosarcoma and Ewing's sarcoma. Indications, feasibility and timing criteria of surgical treatment have been reviewed and extracted from literature. Our case series is also presented.

Salvage surgery after radiation failure in squamous cell carcinoma of the larynx.

AIM AND BACKGROUND: To investigate patients treated with radiotherapy (RT) for laryngeal squamous cell carcinoma (SCC) in order to estimate the recurrence rate and treatment used as salvage surgery. The survival rate in the group of patients treated with salvage surgery was compared to that of patients who had chemotherapy rather than surgery or who refused any treatment. METHODS: From 1989 to 1999, 185 patients came to our institution for laryngeal SCC. All of them underwent RT as primary treatment. Only patients with a minimum of three years follow-up (n = 143) were included in the study group. RESULTS: The 143 cases included 22 loco-regional recurrences (15.3%) during the minimum three years of follow-up. Recurrence was observed in the larynx in eighteen cases (81.8%), in cervical nodes in one case (4.55%) and in both the larynx and cervical nodes in one case (4.55%). There was peristomal recurrence in two cases (9.1%). Recurrence was observed after an average of 16.3 months. Fourteen patients (63.6%) out of the twenty-two cases of recurrence underwent salvage surgery. Surgery was not performed on the remaining eight patients (36.4%). The global survival rate was 92.3% after three years and 66.6% after five years in the group of patients treated with surgery. The actuarial survival rate was 100% after three years and 83.3% after five years. The global and actuarial survival rate was 20% after three years and 0% after five years in the group of patients who received chemotherapy rather than surgery or who refused any kind of treatment. CONCLUSION: The RT seems to play an important role in the loco-regional control of laryngeal SCC (especially in glottic T1). Salvage surgery for recurrence results in a good survival rate.

The pectoralis major myocutaneous flap in head and neck reconstructive surgery: 16 years of experience.

Wide defects resulting after resection of malignant tumors of the head and neck need an adeguate closure. In the last 16 years, 85 pectoralis major myocutaneous island flap procedures were carried out for the immediate reconstruction of surgical defects following extirpation of malignant tumors at various sites of the upper aerodigestive tract. The final functional and cosmetic results were satisfactory. Partial necrosis was observed in four cases. We did not have any cases of total flap necrosis. Post-operative fistulas were encountered in 14 cases (surgical closure was not necessary). The application and complications of the pectoralis major myocutaneous flap placed at cervical level are reviewed. The aspects of postoperative swallowing function of such surgery are discussed. Reconstruction with the pectoralis major myocutaneous flap is a safe and versatile procedure, yielding good clinical and functional results in patients with advanced head and neck tumors.
