RESUMO
Tongue defects following resection of cancers, have a major effect on speech and swallowing, impairing the quality of life. Free flaps such as the free radial artery forearm flap and anterolateral thigh flap have been ideal for the reconstruction of such defects depending upon the volume of tissue loss. Local flaps such as the submental flap and pectoralis major myocutaneous flap serve as an alternative in decreasing morbidity and improving functional outcomes. Surgical outcomes associated with submental flaps used in the reconstruction of tongue defects were evaluated in our study. This is a retrospective analysis of 545 patients, where the submental flap was used for the repair of tongue defects for cancer resections. Oncological safety was studied in 375 patients with a median follow-up of 48 months. 140 patients were studied for their functional outcomes using the parameters, adapted from the University of Washington- Quality of Life questionnaire. Complete flap loss was seen in 15(2.75%) patients while 22(4.03%) patients had partial loss of flap. Locoregional Recurrences, second primary, and distant metastases were noted in 91 of the 375 patients studied. The mean score for swallowing, speech, and taste were 72,71, and 69 respectively. The submental flap is an effective and reliable alternative for the reconstruction of tongue defects.

RESUMO
Background: Operable stage IV gingivobuccal complex cancer is classified as Stage IVA and IVB. Among patients with Stage IVA disease, different subgroups with likely different prognoses are combined. Patients with advanced nodal status tend to have a poorer prognosis. We divided these patients into four groups: group I (T4aN0), group II (T4aN1-2), group III (T1-3N2) constituting stage IVA category, and group IV (TanyN3) representing stage IVB. This study assesses if these patients can be prognostically subgrouped based on nodal status. Methods: It is a prospective observational study done at a tertiary care center from July 2017 to June 2020. This study aims to analyze survival outcomes in these subgroups using Kaplan Meir, univariate and multivariate analysis. Results: The study enrolled 113 patients of operable gingivobuccal complex stage IVA cancer with a median follow up of 26 months, disease-free survival (DFS) was 74% for group 1, while it was 55%, 26% and 32.2% for group 2, group 3 and group 4 respectively. Patients with T4N3 disease had DFS of just 15%. Patients in group 3 and 4 had the worst outcomes in terms of DFS and Overall Survival(OS) with HR-3.7 and 3.3 and 3.3 and 3.8 respectively (p value-0.001). Conclusion: The nodal status is the most important prognostic factor affecting DFS and OS. Patients with small primary but advanced nodal stage do poorly than patients with advanced primary and node-negative disease. There is a need for subgrouping patients with Stage IVA tumors based on nodal status for better prognostication.
RESUMO
Amongst oral cancers, malignancies of the palate and the upper gingivo-buccal complex are relatively uncommon. Following resection, defects in the palate lead to a nasal speech and nasal regurgitation on swallowing. This is best overcome with a prosthetic obturator which occludes the palatal defect and has dentures for the upper alveolus. It may not be possible to fit a prosthetic obturator in edentulous patients and in patients with trismus. Microvascular free flaps though commonly used for such defects, are time consuming, expensive and require a specialised setup. This study assesses the submental flap for its feasibility to repair palatal defects, the sturdiness of the flap, its functional outcome and the oncological safety in using the flap. This is a retrospective analysis of 46 patients, where palatal defects for oral cancers were reconstructed with the submental flap. Oncological safety was studied in 41 patients with a median follow-up of 34.5 months. 20 patients were studied for their functional outcomes using the parameters, adopted from the University of Washington-Quality of Life questionnaire. Complete flap loss was seen in 4 (8.7%) patients while 2 (4.35%) patients had minor dehiscence. No donor site morbidity was reported. Locoregional Recurrences and distant metastasis were noted in 13 of the 41 patients studied. The mean score was highest for speech at 95.5% while the lowest mean score was for mouth opening at 42.5%. The submental flap is an effective and reliable alternative for the reconstruction of palatal defects.
RESUMO
(1) To study layer of invasion as predictor of cervical lymph node metastasis. (2) To decide a cut off depth according to layer of invasion for neck dissection. It is a prospective study with sample size of 220 patients at tertiary care hospital with previously untreated operable buccal mucosa carcinoma over period of 21 months. The factors considered under the study were Tumor layer of invasion, lymph node metastasis, Ultrasonography doppler neck, CT scan and gender. Wide excision of the lesion and reconstruction was done. Histopathological analysis of resected specimen were recorded as part of data collection for all the cases. Quantitative data represented using Mean ± SD (Standard Deviation) and median and interquartile range compared using Chi square test. Standard principles of univariate analysis was used according to statistical methods. Depth when measured according to layer of invasion, was significantly associated with lymph node metastasis with 89% of the muscle as layer of invasion being Lymph node positive (p = 0.009). There is 1.39 times chances of lymph nodal metastasis in patients with muscle invasion as compared to submucosal invasion. Tumour layer of invasion plays important role in predicting chances of nodal metastasis in clinically N0 neck in buccal mucosa cancer. According to the study, we should electively proceed with ipsilateral lymph node dissection once the layer of tumour invasion is muscle. This study is limited by sample size and short duration of one year and nine months.
RESUMO
BACKGROUND: Free-flap reconstructions (FFRs) are the standard-of-care following resections for oral cancer. This study assessed an alternative, the pedicled submental flap (SF) for its versatility, oncological outcomes, and comparative operative time and cost. METHODS: This was a longitudinal prospective study of 1169 patients of oral cancer reconstructed with the SF. Oncological outcomes in terms of recurrence rate and disease-free survival (DFS), were analyzed in 730 cases with a minimum of 18 months follow-up. Surgical time and cost were compared between 20 SFs and 14 FFRs performed consecutively. RESULTS: SF was used to reconstruct defects in the cheek (29.2%), mandible (41.6%), tongue (26.3%) and palate (2.7%) with a 94% flap survival. N+ at level 1 did not adversely affect the recurrence rate as compared with N+ at levels other than level 1 (27.52% vs 29.81%). SFs took a shorter time (186 minutes vs 474 minutes) and cost significantly less than FFRs (P < .0001). CONCLUSIONS: SF can reconstruct various oral defects, is sturdy, and esthetically and functionally satisfactory. The procedure time is much shorter than for FFR and costs considerably less. With careful case selection and meticulous clearance, SF reconstruction is oncologically safe even in N+ neck.
RESUMO
To evaluate the quality of life (QOL) of oral cancer patients who had undergone surgical reconstruction with nasolabial flap. A cross-sectional study was conducted over a period of 1 year at a tertiary care hospital and 128 subjects were included. The subjective assessment of quality of life using The University of Washington QOL Questionnaire including physical, socio-emotional, composite and overall QOL, Objective assessment of functional mouth opening and Nasolabial crease scar assessment using Vancouver scar scale was done. Majority of the subjects, 98.4% were male. Maximum cases were involving the lower gingivobuccal complex and retromolar trigone followed by buccal mucosa. Majority of the tumors were T2, 53.1% followed by T1, 18.8%. Statistically significant (p < 0.05) difference was found in relation to age, tumor size (T1, T2, T3), absence of adjuvant radiation therapy, presence or absence of neck dissection, tumor site; buccal mucosa and lower gingivobuccal complex plus retromolar trigone and intact bone status in physical functional, social-emotional subscores, composite score and overall QOL assessment. Improved mouth opening postoperatively was statistically significant (p < 0.05) in T1 and T2 lesions of buccal mucosa and lower gingivobuccal complex plus retromolar trigone who did not receive radiation and with intact bone status. Majority of the cases, 36.7% had a nasolabial crease scar score 2. Nasolabial flap is a viable option in the reconstruction of small and medium sized oral defects with good quality of life (QOL) outcome and objective outcome as depicted by significantly improved mouth opening. The aesthetic outcome of nasolabial crease scar is good in our study.
RESUMO
INTRODUCTION: Hospitalization is an important setting to address tobacco use. Little is known about post-discharge cessation and treatment use in low- and middle-income countries. Our objective was to assess tobacco use after hospital discharge among patients in Mumbai, India. METHODS: Longitudinal observational study of inpatients (≥15 years) admitted at one hospital from November 2015 to October 2016. Patients reporting current tobacco use were surveyed by telephone after discharge. RESULTS: Of 2894 inpatients approached, 2776 participated and 15.7% (N = 437) reported current tobacco use, including 5.3% (N = 147) smokers, 9.1% (N = 252) smokeless tobacco (SLT) users, and 1.4% (N = 38) dual users. Excluding dual users, SLT users, compared to smokers, were less likely to report a plan to quit after discharge (42.6% vs. 54.2%, p = .04), a past-year quit attempt (38.1% vs. 52.7%, p = .004), to agree that tobacco has harmed them (57.9% vs. 70.3%, p = .02) or caused their hospitalization (43.4% vs. 61.4%, p < .001). After discharge, 77.6% of smokers and 78.6% of SLT users reported trying to quit (p = .81). Six-month continuous abstinence after discharge was reported by 27.2% of smokers and 24.6% of SLT users (p = .56). Nearly all relapses to tobacco use after discharge occurred within 30 days and did not differ by tobacco type (log-rank p = .08). Use of evidence-based cessation treatment was reported by 6.5% (N = 26). CONCLUSIONS: Three-quarters of tobacco users in a Mumbai hospital attempted to quit after discharge. One-quarter reported continuous tobacco abstinence for 6 months despite little use of cessation treatment. Increasing post-discharge cessation support could further increase cessation rates and improve patient outcomes. IMPLICATIONS: No prior study has measured the patterns of tobacco use and cessation among hospitalized tobacco users in India. Three-quarters of tobacco users admitted to a hospital in Mumbai attempted to quit after discharge, and one-quarter remained tobacco-free for 6 months, indicating that hospitalization may be an opportune time to offer a cessation intervention. Although smokers and SLT users differed in socioeconomic status, perceived risks and interest in quitting, they did not differ in their ability to stay abstinent after hospital discharge.

Oral cancer is a major public health concern in the Asian countries predominated by India which accounts for 33.81% of the annual global oral cancer burden. The well-established high-risk factors associated with oral cancer include tobacco, areca nut, alcohol consumption, and high-risk human papilloma virus types 16/18. Additionally, in the past two decades, the critical role of the genomic constitution of individuals in oral cancer susceptibility has emerged. Accumulating evidence indicates the association of several single nucleotide polymorphisms (SNPs) with oral cancer risk. Thus in the current study, we assessed the association of thirteen SNPs in seven transcription factor genes along with HBB (a control SNP) to identify high-risk genotypes associated with increased oral cancer risk in an Indian cohort of tobacco habitués. Fourteen SNPs were investigated in 500 patients with oral cancer and 500 clinically healthy long-term tobacco users as controls of Indian ethnicity. Allelic discrimination real-time polymerase chain reaction was the method of choice for genotyping the samples. Logistic regression analysis was performed and the association of SNPs with oral cancer risk was estimated using odds ratio (OR) and 95% confidence interval (CI). We observed five SNPs-rs2051526 (ETV6), rs6021247 (NFATC2), rs3757769 (SND1), rs7085532 (TCF7L2), and rs7778413 (SND1) indicating increased oral cancer risk with OR ranging from 1.61 to 34.60. Further, as a proof of concept, the coinheritance of high-risk genotypes in rs6021247 (NFATC2) GG (OR, 2.77; CI, 2.09-3.69) and rs7778413 (SND1) CC (OR, 34.60; CI, 17.32-69.13) reflected further increase in the risk with OR-49.94 (CI, 16.25-153.48). The present study indicates the association of transcription factor SNPs with increased oral cancer risk constituting "predictive biomarkers" in oral cancers.

BACKGROUND: Oral cancer has a high incidence primarily because of tobacco chewing habits. However, a small proportion of habitués develop oral cancer, implying a role for genomic variants in its susceptibility. METHODS: Thirteen single nucleotide polymorphisms (SNPs) in an Indian cohort comprising patients with oral cancer (n = 500) and healthy controls (n = 500) were genotyped using allelic discrimination real-time polymerase chain reaction (PCR). RESULTS: Prevalence of SNPs rs11130760, rs1957358, rs2306058, rs4883543, rs12637722, rs1457115, rs2353292, rs709821, rs2194861, rs4789378, rs3827538, rs2667552, and rs2886093 was determined in the Indian cohort. A significant association of rs11130760 GG (odds ratio [OR] 1.41; 95% confidence interval [CI] 1.08-1.84) and rs1957358 TT (OR 1.44; 95% CI 1.10-1.90) indicated increased risk; whereas rs1957358 TC (OR 0.67; 95% CI 0.53-0.87) and rs2306058 CT (OR 0.72; 95% CI 0.56-0.93) reflected decreased risk. The SNP rs11130760 wild-type (WT) allele G indicated an increased risk for oral cancer (OR 1.38; 95% CI 1.09-1.73), whereas SNP allele T indicated a decreased risk (OR 0.73; 95% CI 0.58-0.92) for oral cancer. CONCLUSION: Our study identified SNPs with susceptibility to oral cancer in high-risk populations.

Oral cancer is a high incidence cancer in India primarily due to the prevalent tobacco/areca nut chewing habits and hence a major health concern. India constitutes 26% of the global oral cancer burden. Besides the well-established risk factors, the genomic constitution of an individual plays a role in oral cancer. The aim of the current study was to analyse genomic variants represented as single nucleotide polymorphisms (SNPs), analyse their prevalence and investigate risk association of allelotypes/genotypes to oral cancers. Eleven SNPs in genes associated with biological functions were analysed in an Indian cohort (n = 1000) comprising 500 oral cancer patients and 500 long term tobacco habitués as controls, using Allelic discrimination Real-Time PCR assay with SYBR Green dye. Fisher's exact test and Odds Ratio were used for statistical analysis. Increased risk was observed for rs9849237 CC [P = 0.008; OR 1.412 (1.09-1.82)] and rs243865 CT [P = 0.004; OR 1.469 (1.13-1.90)] genotypes, whereas rs9849237 CT [P = 0.034; OR 0.755 (0.58-0.97)], rs243865 CC [P = 0.002; OR 0.669 (0.51-0.86)] and rs10090787 CC [P = 0.049; OR 0.774 (0.60-0.99)] genotypes indicated decreased risk to oral cancer. The other SNPs showed equidistribution in both groups. Our data indicated genotypes and alleles in specific SNPs rs9849237, rs243865 and rs10090787 with increased/decreased risk to oral cancer.

OBJECTIVE: To analyze various demographic, clinical, and histopathologic factors in T1-2 N0 squamous cell carcinoma (SCC) of the oral tongue to define a high-risk group for regional recurrence that will benefit from elective neck dissection. MATERIALS AND METHODS: Retrospective outcome analysis of a patient cohort without palpable or ultrasound (USG) detectable nodal metastases undergoing per oral wide glossectomy for T1-2 N0 SCC of oral tongue. Patients were followed up using palpation and serial USG neck and fine-needle aspiration cytology. RESULTS: Of the 176 patients, 69 (39%) showed recurrence during follow-up. Fifty-eight cases developed regional neck node metastases, i.e., overall regional node recurrence rate of 33%. Fifty-three (91%) with regional neck node metastases were salvaged successfully with further treatment. In 110 cases with tumor thickness more than 5 mm, 39% cases developed regional neck node metastases. This association was significant with P = 0.0402. Among 44 cases with perineural invasion, 54% developed regional neck node metastases. Similarly in 39 cases with lymphovascular invasion, 61% developed regional neck node metastases. Association of both of these parameters with the development of regional neck node metastases was significant. CONCLUSION: We recommend prophylactic selective neck dissection in early stage SCC of oral tongue, especially with depth of invasion more than 5 mm, perineural and lymphovascular invasion.
RESUMO
Oral cancer incidence of 77,003 poses a major health concern in India, with 5-10 % tobacco habitués developing oral cancer. The current study examined the role of specific genomic variants in oral cancer. We examined five genomic variants represented as single nucleotide polymorphisms (SNPs) in genes associated with cell proliferation and cellular invasion. The SNPs rs2124437 (RASGRP3), rs1335022 (GRIK2), rs4512367 (PREX2), rs4748011 (CCDC3), and rs1435218 (LNX1) were analyzed in 500 histopathologically confirmed oral cancers and 500 healthy controls with a minimum of 10 years of tobacco usage. Allelic discrimination real-time PCR SYBR Green assay was used. The genotypic and allelic frequencies between cases and controls were analyzed using SPSS software (version 19) and odds ratio (OR) using Hutchon.net, indicating increased risk to oral cancers. A significant association of the SNPs in oral cancer was observed in RASGRP3 AA (rs2124437) (p < 0.000, OR 1.34, 95 % confidence interval (CI) 1.01-1.76), GRIK2 TT (rs1335022) (p = 0.008, OR 1.58, 95 % CI 1.23-2.03), PREX2 CC (p = 0.008, OR 1.56, 95 % CI 1.15-2.1), and TT (p < 0.000, OR 2.77, 1.68-4.57) genotypes, whereas the heterozygous genotypes showed higher frequencies in controls, i.e., GRIK2 CT (rs1335022) (p = 0.029, OR 0.68, 95 % CI 0.53-0.87) and PREX2 CT (p = 0.004, OR 0.49, 95 % CI 0.37-0.64), indicating protection. Coinheritance of the SNPs was associated with further increase in the risk. Thus, the SNP genotypes in the three genes, present singly or as a coinherited panel constituted "Predictive Biomarkers" indicating increased risk of oral cancer in tobacco habitués.

Peripheral primitive neuroectodermal tumor (PNET) is a rare histology to be found in primary tumors of the kidney. There are less than a hundred cases reported in the English literature. Most of these have been diagnosed after surgery for a renal neoplasm diagnosed on imaging. PNET has rarely been reported as a second malignancy, and has never been reported as a second malignancy after non-Hodgkin's lymphoma (NHL). Herein, we present our case of a 38-year-old female who developed a second malignancy in the kidney after the treatment for NHL.

OBJECTIVES/HYPOTHESIS: To study and compare the outcome of trans-oral CO2 laser microsurgery for early glottic squamous cell cancer with and without the involvement of anterior commissure (AC). STUDY DESIGN: This is a retrospective analysis of 296 cases of early glottic squamous cancer treated by trans-oral CO2 laser microsurgery. METHODS: The patients were divided into two groups depending on whether AC was involved or not. The impact of AC involvement on rates of local recurrence, laryngeal preservation, overall survival, and disease-specific survival was compared in both the groups. RESULTS: Out of the 296 cases, 61 cases had AC involvement, while in 235 cases AC was free of disease. Local recurrence rate was significantly higher at 29.51% in the group with AC involvement, while only 18.3% cases had local recurrence in the group without AC involvement with P value of 0.0001. On T stage-wise analysis, 34.8% cases of T2 lesions with AC involvement developed local recurrence, as compared to only 10.26% cases of T2 without AC involvement with significant P value of 0.007. Larynx preservation rate was 95.8% versus 93.26% in the AC-involved and AC not-involved cases, respectively, without any statistical significance (P=0.287). The overall survival was 90.16% versus 86.38% in the cases with and without AC involvement, respectively, without significant P value 0.642. CONCLUSIONS: Trans-oral laser surgery is an excellent treatment option in patients with early glottic cancer irrespective of whether or not the AC is involved. Trans-oral laser microsurgery for early glottic cancer involving AC requires adequate exposure, proper assessment, good experience, and advanced surgical skills.

OBJECTIVES/HYPOTHESIS: The purpose of the study was to study the outcomes of per oral wide excision of early T1-2 N0 squamous cell cancer of buccal mucosa. METHODS: This is a retrospective study of early and localized squamous cell cancer of the buccal mucosa treated with peroral wide excision at a tertiary-care hospital. RESULTS: A total of 156 patients were analyzed. One hundred ten patients (70.5%) had no recurrence, whereas 15 (9.6%) had a local recurrence, 24 (15.4%) had regional metastasis, three (1.9%) had locoregional recurrence, and four (2.6%) developed second primary tumors over a median follow-up of 48 months. Most patients with local recurrences (14 patients, 93.3%) and regional metastases (24 patients, 100%) could be salvaged with treatment. In contrast, all three cases with locoregional could not be salvaged. Most of the cases with recurrences, 36 (78%) in this study group, occurred within 2 years of primary treatment. Out of 143 cases with a habit of tobacco/beetel quid chewing, premalignancy was seen in 62 (43.4%) cases, showing a statistically significant association with P-value of 0.012. Fifteen (21.4%) cases with stage T2 developed regional neck nodes, while only 9 (10.5%) cases with stage T1 developed regional neck nodes with P-value of 0.032. Three-year overall survival rate and disease-free survival rates were 91.7% and 70.5%, respectively. CONCLUSIONS: Peroral wide excision seems to be an adequate procedure for T1-2N0 localized squamous cancer of buccal mucosa. Prophylactic selective neck dissection should be considered in only T2 N0 cases as only T stage of the disease could be significantly correlated with the development of the metastatic neck nodes.

Papillary thyroid cancer favors lymphatic spread both within the thyroid gland and to the cervical lymph nodes. Hematogenous spread rarely occurs in the lung, bones and brain. We report a case where metastatic nodules from papillary thyroid cancer were seen in the right aryepiglottic fold (supraglottis) and lateral wall of hypopharynx, an extremely rare event.

Introduction Impact of treatment and prognostic indicators of outcome are relatively ill-defined in esthesioneuroblastomas (ENB) because of the rarity of these tumors. This study was undertaken to assess the impact of craniofacial resection (CFR) on outcome of ENB. Patients and Methods Data on 151 patients who underwent CFR for ENB were collected from 17 institutions that participated in an international collaborative study. Patient, tumor, treatment, and outcome data were collected by questionnaires and variables were analyzed for prognostic impact on overall, disease-specific and recurrence-free survival. The majority of tumors were staged Kadish stage C (116 or 77%). Overall, 90 patients (60%) had received treatment before CFR, radiation therapy in 51 (34%), and chemotherapy in 23 (15%). The margins of surgical resection were reported positive in 23 (15%) patients. Adjuvant postoperative radiation therapy was used in 51 (34%) and chemotherapy in 9 (6%) patients. Results Treatment-related complications were reported in 49 (32%) patients. With a median follow-up of 56 months, the 5-year overall, disease-specific, and recurrence-free survival rates were 78, 83, and 64%, respectively. Intracranial extension of the disease and positive surgical margins were independent predictors of worse overall, disease-specific, and recurrence-free survival on multivariate analysis. Conclusion This collaborative study of patients treated at various institutions across the world demonstrates the efficacy of CFR for ENB. Intracranial extension of disease and complete surgical excision were independent prognostic predictors of outcome.
RESUMO
The advent of transoral microlaryngoscopic laser surgery is making a significant impact on treatment decisions in the management of early squamous cancers of the larynx and the hypopharynx. It has, to a great extent replaced the conventional open partial laryngectomy procedures. Moreover many cancers of the larynx or the hypopharynx that were earlier being treated with radiation therapy are now resected transorally with the CO(2) laser. This article focuses on the progress of transoral laser microsurgery in the management of early larygopharyngeal cancers.
