Background: Solid organ recipients are at an increased risk of developing various malignancies. We investigated the incidence, clinical features, and outcome of patients diagnosed with head and neck cancer after organ transplantation., Methods: A retrospective analysis was undertaken of patients who underwent solid organ transplantation (kidney, liver, lung, heart) treated at our institution from 1992 to 2010., Results: Of 2817 organ recipients, 175 patients (6.1%) developed 391 head and neck malignancies. Cutaneous malignancies were the most common (93%): squamous cell carcinoma (SCC; 51%) and basal cell carcinoma (BCC; 42%). The average interval from transplantation to diagnosis of head and neck malignancy was 7.3 years, with liver recipients diagnosed earlier. Eighteen percent of patients presented with an aggressive pattern of head and neck cancer, including 24% of patients with cutaneous SCC., Conclusion: Organ transplantation recipients are at a higher risk to develop head and neck cancer with an aggressive behavior characterized by multiple recurrences and decreased survival., (Copyright © 2013 Wiley Periodicals, Inc.)

Background: Failure rate of surgery for early tongue carcinoma remains high. We sought to identify patterns of failure and recurrence risk factors., Methods: Data review was carried out on 50 patients treated for early tongue carcinoma (T1/2N0M0); surgery was unsuccessful in 11 of these patients. All patients underwent transoral resection of the tongue tumor and prophylactic neck dissection (supraomohyoid)., Results: Tumor recurred within 3 to 18 months. Nine died of disease. Four had failure in neck level 4, 6 in level 1, and 1 simultaneously in level 1 and locally. Most tumors were moderately differentiated. Average depth was 6.64 mm., Conclusions: We report 11 patients with early tongue carcinoma who failed local excision with neck dissection. Failures occurred in level 4 (4 patients) and level 1 (7 patients). This group may benefit from extended neck surgery. Sex, age, stage, and depth of tumor were not significantly different in the group with treatment failure. Tumors in the group with treatment failure were more poorly differentiated., (Copyright © 2011 Wiley Periodicals, Inc.)

Background: The value of intraoperative parathyroid hormone (IOPTH) monitoring in parathyroidectomy has been previously debated., Methods: This retrospective analysis was of 240 patients, operated on for primary hyperparathyroidism (PHPT) between January 2002 and January 2006 and categorized into 3 groups by preoperative and intraoperative modalities: group 1 (n = 109), technetium 99m sestamibi (MIBI), ultrasonography, and IOPTH; group 2 (n = 102), ultrasonography and MIBI; and group 3 (n = 29), ultrasonography and IOPTH. Sensitivity and specificity were calculated., Results: In group 1, IOPTH increased the success rate from 97% to 99%. In group 2, ultrasonography and MIBI were concordant in 95% of cases. In group 3, IOPTH increased the sensitivity from 89% to 96%. The duration of surgery was longer (p < .0001) when IOPTH was applied., Conclusions: When ultrasonography and MIBI are used, the additional benefit of IOPTH is marginal, especially given the longer duration of surgery. Ultrasonography and additional IOPTH yield good success rates when MIBI is not available., (Copyright © 2011 Wiley Periodicals, Inc.)

Background: Follicular carcinomas of the thyroid are less common than papillary carcinomas of the thyroid, and the available data on prognostic factors are relatively scant. A retrospective study covering four decades was undertaken to evaluate clinical and pathologic findings with regard to their effect on prognosis., Methods: In 195 cases of follicular carcinoma treated from 1954 to 1991 age, sex, histologic type (minimally invasive vs. widely invasive), tumor size, and local, regional, and distant spread as well as the contribution of treatment to survival were evaluated in relation to prognosis., Results: Age was a significant prognostic factor: there was 100% survival of patients younger than 20 years of age at diagnosis and only one death in the 20-39 year age group. Sex was not a significant prognostic factor, although there was a tendency to a better prognosis in females. Tumor size was significant, more than 6 cm having a poor prognosis. Blood vessel invasion influenced prognosis for the first 10 years. The presence of distant metastases was significant regarding survival. Lymph node involvement had a negative effect on the outcome., Conclusions: The factors of age, tumor size, invasion of blood vessels, and distant metastases are significant predictors of survival for patients with follicular carcinoma, whereas sex is not; regional spread needs to be evaluated further.

According to common classification and staging systems, tumors of the uvula and soft palate are included in the group of oropharyngeal cancers. As such, the same staging systems apply and therapeutic decisions are made accordingly. Our experience with small tumors of the uvula and midline soft palate has shown that these common rules may not apply in these anatomical sites. A multicenter retrospective study was performed to examine the aspects of presentation and clinical course of tumors of the uvula. Only patients with small tumors, less than 2.0 cm in diameter, were included. Twenty-three cases were reviewed. Eleven (47.8%) patients had clinical or radiologic evidence of neck disease on presentation. Five of 12 (41.7%) patients who presented with negative neck were found eventually to have neck disease. Eight patients had cervical recurrence. Only one patient had local recurrence. We suggest that attention may need to be directed to the treatment of the neck of all tumors of the uvula and midline soft palate, regardless of size.
