RESUMEN

Introduction: Biologic aggressiveness of OSCC (Oral Cavity Squamous Cell Carcinoma), has intrigued research in various prognosticating histopathological markers over past few decades. DOI (Depth of Invasion) is one such histopathological factor which affects outcomes and was included in the AJCC 8th edition TNM staging. Pattern of Invasion (POI) has been widely reported as an adverse prognostic factor associated with higher locoregional failure and poor prognosis. However, these factors are not utilized for treatment decision making and for outcome assessment. Materials and methods: This is a retrospective analysis of 320 patients with OSCC who underwent treatment, from October 2018-February 2020. Clinic demographic details were extracted from electronic medical records. Univariate and multivariate analysis was done for the parameters. WPOI (Worst Pattern of Invasion) was correlated with all histopathological prognostic factors. Survival analysis was done using Kaplan Meier for WPOI type's I-V. DFS (Disease free Survival) was evaluated for different grades of WPOI. Results: We analyzed the results comparing, early and advanced T (Tumor) stages, cohesive WPOI I-III, non-cohesive WPOI IV-V. Univariate analysis showed a significant association of T-stage (p = 0.001), N (Nodal) -stage (p = 0.002), DOI (p = 0.008), PNI (Peri-neural invasion) (0.001) and Tumor differentiation Grade (p = 0.001). On multivariate analysis, non-cohesive WPOI (IV & V) showed significant association with grade, PNI, DOI (0.002, 0.033 & 0.033 respectively). Non-cohesive WPOI had significantly higher locoregional failures and short DFS. Conclusion: Presence of invasive WPOI is associated with advanced T stage, poor differentiation, PNI, greater depth of invasion, and higher chances of nodal metastasis. WPOI is associated with poor DFS, treatment intensification in early stage disease with WPOI type IV & V may improve survival.

RESUMEN

INTRODUCTION: Lip reconstruction aims at maintaining the function and aesthetics of the facial subunits. Sensation in the reconstructed lip helps in bolus formation, tactile discrimination, and thermal sensation. In this study, we aim to describe random pattern nasolabial flap for lip reconstruction using various functional parameters. METHODOLOGY: This is a retrospective study of 22 patients with carcinoma lip who underwent surgical resection and reconstruction with sensate nasolabial flap. Several clinicopathological parameters were studied. Outcome parameters like oral competence, tactile sensation, thermal sensitivity of reconstructed lip and speech outcomes were evaluated. RESULT: A functional outcome with 2-4 mm of two-point discrimination was obtained in 19 patients. All patients had intelligible speech. A mean sulcus depth of 19.59 mm was achieved. One patient had partial flap loss owing to wound infection. CONCLUSION: Random pattern senate nasolabial flap offers a good functional outcome by maintaining the tactile and thermal sensitivity.

RESUMEN

INTRODUCTION: Thyroidectomy for thyroid cancers and central neck dissection are considered as independent predictors of postoperative hypocalcemia. Post-surgical hypocalcemia is the most common and often the most difficult long-term consequence of thyroid surgeries. Management of hypocalcemia is done with calcium supplementation, but there is no consensus on the timing and the amount of calcium supplementation. MATERIALS AND METHODS: A retrospective study of all thyroid cancer patients who underwent total thyroidectomy at our Centre, from August 2009 to August 2017 was done to evaluate the prevalence of symptomatic hypocalcemia. The patients were grouped into two based on the early and late supplementation of calcium in the form of intravenous calcium gluconate and oral calcium with calcitriol. RESULTS: There were 133 patients of which 109 had papillary carcinoma, 11 had follicular, 3 had hurthle cell and 10 had medullary carcinoma. Of these, 49.6% underwent total thyroidectomy alone and the rest with neck dissection. 38 patients (28.6%) had a unilateral neck dissection and 16 patients (12%) had a bilateral neck dissection. 14 out of the 67 patients (20.9%) who underwent neck dissection developed symptomatic hypocalcaemia, in contrast to only 2 patients out of the 66 (3%) without neck dissection. 31.7% of lateral neck dissection and 7.7% of central compartment dissection had symptomatic hypocalcaemia (p value = 0.0053). 22.5% of patients whose parathyroid were not identified had more symptomatic hypocalcaemia than in whom at least one parathyroid gland was seen (p value=0.0004). Eleven out of 73 patients (15.1%) who were treated late with calcium and calcitriol, and one out of 60 (1.7%) who had early calcium supplementation developed symptoms (p value=0.0073). CONCLUSION: Central compartment and lateral neck dissection were significantly associated with higher incidence of symptomatic hypocalcemia. Early intervention with calcium supplementation reduced the symptoms of hypocalcemia. Identification and preservation of parathyroid glands significantly reduces the hypocalcemia.
