ABSTRACT
Fine needle aspiration cytology (FNAC) reduces the number of unnecessary thyroid surgeries for patients with benign nodules and appropriately triages patients with thyroid cancer to appropriate treatment. This was a observational study done on cases presenting with clinical suspicion of thyroid malignancy which underwent ultrasonography followed by FNAC of thyroid nodule. Ultrasonographic characterization of nodules was based on Thyroid Imaging Reporting and Data System (TIRADS) and cytology reporting was based on Bethesda system. All recruited patients underwent thyroidectomy. Pre-operative cytology and ultrasonography features were compared with final histopathology report. In our study, Bethesda system of cytology reporting for thyroid nodules had a better sensitivity, specificity and diagnostic accuracy than TIRADS system of ultrasound reporting. Bethesda system in FNAC had a larger area under the ROC curve (0.91) as compared to ultrasound TIRADS (0.70). Malignancy rate of TIRADS 5 nodules was 97.1% with significant p value (0.022). 100% of Bethesda VI lesions were malignant according to final histopathology report. Ultrasound TIRADS could pre-operatively predict malignancy in 63.6% of indeterminate thyroid nodules which were malignant according to post-operative histopathology. The overall concordance of ultrasound TIRADS, Bethesda system and histopathology was 69.8%. Higher TIRADS and Bethesda scoring among thyroid nodules was associated with increased risk of malignancy. US TIRADS is a good predictor of malignancy in indeterminate thyroid nodules.
ABSTRACT
Free tissue transfer is the reconstructive option of choice in oral defects of onco-resections. Local flaps like nasolabial flap and FAMM flaps need to be in the armamentarium of surgeons to use when need arises. The aim of this study is to assess utility of island FAMM or nasolabial flap in oral reconstruction, in an oncological setting. Patients with oral cancers, irrespective of nodal status, were included in the study. A total of 33 patients were enrolled from Jan 2018 to Feb 2019, of which 2 were discarded intra-operatively. Fifteen had NLF and 16 had FAMM flap reconstruction. Partial flap loss was noted in 2 patients that healed with granulation, secondarily. Island FAMM and island nasolabial flaps are equally good reconstructive options even in an oncological setup, if factors like addictions, socialising capacity of patient and presence of submucosal fibrosis can be ascertained.

BACKGROUND: In carefully selected oral cavity cancers, marginal mandibulectomy is an adequate procedure which achieves good disease control adhering to the principle of "doing as little as possible and as much as necessary". METHODOLOGY: This was a retrospective study done by reviewing the medical records of all patients who underwent marginal mandibulectomy for resection of oral cavity cancers in our institution during a period of 5â¯years. Data was collected from medical case records and analyzed. RESULTS: 125 cases underwent marginal mandibulectomy for resection of oral cavity cancers. 88.5% of advanced oral cavity cancers that underwent neoadjuvant chemotherapy followed by marginal mandibulectomy are still disease free. The local recurrence rate was 10.4%. Among cases which recurred, 61.5% were in T2 stage of the disease and 30.8% recurred in buccal mucosa. For lesions on the mandible (26/125), the final histopathology showed bone infiltration in only 12% cases and among them only one recurred. Among 88/125 cases where the lesion was abutting mandible even after stretching mucosa, recurrence was noted only in 11.4% with 3-year overall survival of 79.3%. CONCLUSIONS: The low recurrence rate following marginal mandibulectomy in our study shows good locoregional control when performed for a lesion close to or abutting alveolar periosteum. In management of advanced oral cavity cancers, neoadjuvant chemotherapy followed by marginal mandibulectomy was effective in achieving significant locoregional control. For superficial lesions on the mandible, marginal mandibulectomy gives adequate margin clearance resulting in long term survival.
