Malignancy Rate in Thyroid Nodules with Atypia or Follicular Lesion of Undetermined Significance

Abstract Introduction Atypia of undetermined significance (AUS) or follicular lesion of undetermined significance (FLUS) is one of the six diagnostic categories of the Bethesda System for Reporting Thyroid Cytopathology. The prevalence of malignancy among Bethesda category III cytology is variable, ranging from 5% to 37% in the literature. Objective To determine the rate of malignancy in thyroid nodules reported as Bethesda category III. Methods A total of 495 patients underwent surgical intervention for thyroid nodules from January 2015 to December 2017. The present study included 81 cases reported as Bethesda category III, and their medical records were reviewed. Results Out of 495 fine-needle aspiration cytology samples, 81 (16.4%) samples were labeled as AUS/FLUS. Among these 81 patients, the mean age was 43.0 years (±13.9), with only 11 (14%) patients older than 55 years of age.Most of our patients were female (n=69; 85.2%), and the rest were male. The rate of malignancy based on the final histology was of 33.3% (n=27). The majority were 17 cases (21%) of papillary carcinoma, followed by follicular carcinoma (n=6) (7.4%). Conclusion The risk of malignancy can be higher than it is commonly believed, and guidelines should be based on the data from the institutions themselves for a better assessment of the outcomes.

Determination of Factors Associated with Critical Weight Loss in Oral Cavity Carcinoma Patients: A Retrospective Cohort Study

Abstract Introduction Critical weight loss is defined as an unintentional weight loss of ≥ 5% at 1 month or ≥ 10% at 6 months from the start of treatment. Critical weight loss leads to deterioration of the immune function and reduced tolerance to treatment (surgery ± radiochemotherapy) as well as increased complication rates. Objective Critical weight loss, defined as a weight loss of ≥ 5% after 1 month or ≥ 10% after 6 months from the start of treatment, is not uncommon in head and neck cancer patients. We aimed to assess the factors associated with critical weight loss during the treatment of oral cavity squamous cell carcinoma patients. Methods A retrospective cohort study was performed at the Aga Khan University Hospital, in Karachi, Pakistan, on 125 patients. Patients receiving adjuvant therapy were considered exposed, and the outcome was critical weight loss. Results The mean age of presentation was 46.9 ± 12.8 years in patients undergoing surgery and adjuvant therapy, with 119 (79.3%) of them being male and 31 (20.7%) female. One hundred and twelve patients (81.3%) developed critical weight loss at 6 months from the start of treatment, and the only significant variable associated with critical weight loss was the stage of the disease (p= 0.03). Conclusion A large proportion of patients with oral cancer developed critical weight loss requiring a need for intervention. The overall stage of the disease is a significant predictor of critical weight loss in patients undergoing treatment.

Is There Any Benefit of Drain Placement on Postoperative Complications in Patients Undergoing the Sistrunk Procedure?

Introduction Same-day, outpatient Sistrunk procedure is commonly performed to manage thyroglossal duct cyst anomalies and may lead to postoperative complications. Surgical drains are placed to prevent complications, but recent observations show no advantage and rather increased health care costs and patient discomfort. Objective The study evaluated if drain placement in the Sistrunk procedure offers any benefit on postoperative complications. Methods A retrospective analysis of patient records having undergone same-day, outpatient Sistrunk procedure from 2004 to 2014 was done. Of 58 (38 male and 20 female) patients included, 38 did not have drains placed and the remaining 20 had drains placed. Mean and median age of patients was 18.1 and 13.5 years, respectively. Postoperative complications of patients with drains versus those without drains were statistically analyzed. Results Overall, about 10% of patients had hematoma/seroma (H-S), with 6.9% of patients needing aspiration for H-S; 3.4% had wound infections; and 1.7% had pus formation. No statistically significant differences in Sistrunk-related complications between patient groups (with drain or without drain) were seen using Fisher exact (two-sided) test: H-S (p = 0.08); need for aspiration (p = 0.29); wound infection (p > 0.05); and pus formation (p = 0.35). Chi-square test also did not show any significant difference in the groups in terms of number of follow-ups. Conclusion Surgical placement of a drain in the Sistrunk procedure does not seem to offer any advantage in terms of reducing common postoperative complications. Sameday Sistrunk procedure without any drain placement may be a safer alternative without necessitating hospitalization. More studies with larger sample size are needed for further substantiation.(AU)
