A clinicopathological study of oral potentially malignant disorders
Subodh Hosagadde, Jyoti Dabholkar, Nitish Virmani
January-June 2016, 4(1):29-34
DOI

Introduction:
Oral cancer is the leading cause of cancer in India accounting for approximately 40% of the cancer burden. A significant number of these are preceded by precancerous lesions and conditions, together referred to as potentially malignant disorders (PMDs). It is important to screen patients for these conditions as they allow physicians to intervene early for prevention as well as early diagnosis of oral cancer.
Aims:
To study the demographic profile, etiology, clinical profile, and histopathology of oral PMDs.
Materials and Methods:
Patient evaluation was done in the outpatient department of a tertiary referral center, and those who complained of oral mucosal lesions were examined between March 2011 and March 2012. They were evaluated and treated according to their diagnosis and were observed for 1½ years, with minimum of 4 follow-ups.
Results:
Of the 23,380 patients who attended the outpatient department between March 2011 and March 2012, 70 (0.29% incidence) patients had oral potentially malignant lesions. Age group most commonly affected was 21–30 years (28.57%). Males were affected more than females (m = 50; f = 20). Smokeless tobacco was the most common risk factor (58.57%). Among single site lesions, buccal mucosa was most commonly affected. Based on histopathology, “leukoplakia without atypia” was the most common lesion followed by oral submucous fibrosis.
Conclusions:
There is a change in the trend of the age distribution of the oral potentially malignant lesions with younger generation and females being involved more and also a definite relation between tobacco-related abuses and oral lesions.

Does adverse histopathological features like perineural invasion, depth of invasion and lymphovascular invasion warrant adjuvant treatment in early oral squamous cell carcinoma?
Shivakumar Thiagarajan, Sajith Babu Thavarool, Nagendra Kadapa, Hamsa Nandini
July-December 2017, 5(2):71-74
DOI
:10.4103/jhnps.jhnps_41_17
Background:
We know from the existing literature that perineural invasion (PNI), lymphovascular invasion , and depth of invasion (DOI) are important prognostic factor that influence locoregional control in oral squamous cell carcinoma (OSCC). However, there is a lack of robust data in literature to recommend adjuvant treatment when one or more of these soft adverse factors are present in early stage OSCC.
Patients and Methods:
All treatment naïve, early OSCC who received definitive treatment in the form of surgery in the institute between March 2010 and December 2013. The clinical and demographic details, histopathological features, and follow-up details were collected. Factors influencing the recurrence-free survival (RFS), including the soft adverse factors, were analyzed.
Results:
Of the 332 OSCC patients, 70 patients satisfied the eligibility criteria and were included in the study. Majority of them were men (54%), with a mean age of 59 years. All of them underwent surgery and a few received adjuvant treatment (
n
= 9). PNI was seen in 9% (
n
= 6) of the cases, median DOI was 6 mm, lymphovascular emboli was seen in only one patients. PNI was the only soft adverse factor, which influenced the RFS on univariate and multivariate analysis.
Conclusion:
In the present study, PNI seems to be an important soft adverse factor, which influences the RFS. Adding adjuvant radiotherapy may benefit these patients. Prospective studies are needed to further evaluate the need for adjuvant treatment in presence of soft adverse factors, especially PNI, in early OSCC to prevent recurrence.

Incidence of occult metastasis in clinically N0 oral tongue squamous cell carcinoma and its association with tumor staging, thickness, and differentiation
Neena Chaudhary, Rajeev Kumar Verma, Usha Agarwal, Shashank Gupta, Shweta Jaitly
July-December 2017, 5(2):75-78
DOI
:10.4103/jhnps.jhnps_17_17
Introduction:
Oral squamous cell carcinoma (SCC) is the most frequent head and neck cancer. The metastatic dissemination of these tumours usually occurs through the lymphatic system. The presence of occult lymph node metastasis is the most important prognostic factor. The high incidence of occult lymph nodal metastasis is a strong argument for the indication of elective neck dissection. However, there is a high percentage of patients who do not have metastasis in the pathological exam (pN0). Taking a homogenous group of patients all of whom received primary surgical treatment, at the same institution without prior radiotherapy or chemotherapy, applying stringent patient selection criteria, and standard pathological evaluation methods across the group, this study aims to establish predictors of cervical node metastasis in squamous carcinomas of the oral tongue.
Result:
During the study period, a total of 112 patients (98 males and 14 females; Mean age 49.7 years (range 15-70)) underwent resection of the primary tumor with SOND for N0 lymph node status of neck. A total of 1489 lymph nodes were analyzed in this study. Occult metastasis was found in 26 patients (23.2%). T-stage 4 was found to be a statistically significant predictor of occult lymph node metastasis in a cN0 neck. (95% CI, p-value 0.02). There was no correlation between gender, tumor thickness, and tumor differentiation and occurrence of occult metastasis.
Discussion:
Controversy exists over management of the neck in patients with cN0 oral SCC. As is evident there is no consistent statistically significant factor that can be attributed as a predictor of occult metastasis in head and neck cancer of the oral cavity. The search to identify reliable and accurate predictor(s) of occult metastases, or approaches to the management of patients with cN0 oral SCC, must continue. In absence of such predictors, keeping the high incidence of occult metastasis in mind, we recommend END in all cases of N0 OSCC.

Changing trends in antibiotic prophylaxis in head and neck surgery: Is short-term prophylaxis feasible?
Naresh K Panda, Muhammed Shafi, Sourabha K Patro, Jaimanti Bakshi, Roshan Kumar Verma
January-June 2016, 4(1):42-48
DOI
:10.4103/2347-8128.182854
Background:
The duration and dosage of prophylactic antibiotics vary substantially among surgeons. This study explored the outcome and efficiency of short-term antibiotic prophylaxis in head and neck procedures.
Methods:
One hundred and forty-three patients undergoing various head and neck surgical procedures were included. They were categorized into two groups, clean (Group C) and clean-contaminated (Group CC). They received short-term prophylaxis with intravenous (IV) antibiotics. Group C patients received single dose IV antibiotic at induction and Group CC received antibiotic for 3 days. The scoring methods such as American Society of Anesthesiologist (ASA) score, National Nosocomial Infections Surveillance (NNIS) score, and additional treatment, discharge, erythema, purulent discharge, separation of deep tissue, isolation of bacteria and stay (ASEPSIS) were used. Scoring methods were used to analyze the risk factors and complications up to a period of 4 weeks postoperatively.
Results:
There were 83 patients in Group C and 60 patients in Group CC. Parameters such as body weight, body mass index (BMI), biochemical and hematological parameters along with surgical details, and postoperative wound assessment were analyzed. A significant association of surgical site infection (SSI) with BMI, anemia, hypoalbuminemia, and tobacco usage was noted along with a high incidence of SSI in surgical procedures involving the larynx. There was no significant relationship with ASA score and NNIS score.
Conclusion:
Short-term antibiotic prophylaxis in clean and clean-contaminated cases is feasible and effective as long-term prophylaxis. Correction of anemia, hypoalbuminemia, weight reduction, and avoidance of tobacco can prevent SSIs.

Santosh Kumar Swain, Asirbad Jena, Mahesh Chandra Sahu, Anwesha Banerjee
July-December 2017, 5(2):66-70
DOI
:10.4103/jhnps.jhnps_29_17
Introduction
: Eagle's syndrome (ES) is defined as the elongation of styloid process or the calcification of the stylohyoid ligament causing clinical manifestations such as throat pain, odynophagia, dysphagia, headache, and irradiation of pain into the ear and neck pain. The clinician misses the diagnosis due to nonspecific clinical presentations.
Objective
: To study detail clinical profile and management of the patients with ES in a tertiary care teaching hospital of eastern India.
Materials and Methods:
Twenty-one patients with ES were included in our study. Diagnosis of the ES was based on clinical presentations and three-dimensional computed tomography (3D CT scan). All were treated through transoral approach under general anesthesia.
Results:
3D CT is very useful for preoperative estimation of the styloid process length. There were no postoperative complications encountered. Chief symptoms of the patients were regressed after surgery.
Conclusion:
Clinical presentations and three dimensional CT are important for exact diagnosis of ES. The transoral approach is a safe and definitive treatment of ES.

A number of qualitative and quantitative ultrasound (US) risk stratification systems for thyroid nodules are being used all over the world, new ones are being devised but so far, no consensus on a single system has emerged. Efforts by the worldwide medical community involved in the management of thyroid nodules are converging toward US risk stratification systems, which could provide a high-sensitivity and high-negative predictive value (NPV) for the diagnosis of clinically significant thyroid carcinomas. In this article, we review the fascinating journey of thyroid US-based thyroid imaging reporting and data system (TIRADS), the changing trends in TIRADS and emerging stratification systems to assess the risk of malignancy. Our recommendation is to develop a comprehensive system of risk stratification which incorporates clinically relevant as well as radiological risk factors and aims to accurately predict the risk of malignancy and oncologic outcome for each patient.

Squamous cell carcinoma of gingivobuccal complex: Literature, evidences and practice
Dushyant S Mandlik, Suraj S Nair, Kaustubh D Patel, Karan Gupta, Purvi Patel, Parin Patel, Nitin Sharma, Aditya Joshipura, Mitesh Patel

Gingivobuccal cancer (GBC) is the most common oral cavity cancer (OCC). Its incidence is increasing with increased use of tobacco and areca nut chewing in third world countries especially the Indian subcontinent. It comprises buccal mucosa, gingivobuccal sulcus, alveolus and retromolar area cancers. OCCs comprise 12% of all male cancers in India, 40% of these are GBCs. Certain precancerous conditions and lesions such as submucous fibrosis, leukoplakia and erythroplakia are known. In special situations such as trismus, examination and early detection becomes difficult. Computed tomography scan is an investigation of choice. Tumor node metastasis staging gives adequate information for treatment selection and prognosis. Surgery remains the mainstay of curative treatment. Due to its unique proximity to mandible and posteriorly infratemporal fossa, extent of surgery remains critical to provide cure with satisfactory functional and esthetic outcomes. Marginal mandibulectomy has consistently provided these results in carefully selected patients. More advanced cancers need segmental or hemimandibulectomy and appropriate reconstruction-preferably free microvascular bone and soft-tissue transfer. Radiotherapy is used in adjuvant setting to reduce locoregional recurrences. It can also be used as palliative modality in advance cases. The role of chemotherapy is investigational; however, criteria have been defined for its use concurrent with radiation in adjuvant postoperative settings in high-risk patients. Cure rates are as high as 85% in early stages and as low as 0%–20% in advance stages. Follow-up strategy is aimed at detection of locoregional failure initially and prevention and management of second cancers.

Evolving role of immunotherapy in head-and-neck cancers: A systemic review
Raajit Chanana, Vanita Noronha, Amit Joshi, Vijay Patil, Kumar Prabhash
January-June 2018, 6(1):2-11
DOI

Head-and-neck squamous cell cancers (HNSCCs) are one of the most common cancers worldwide and account for more than half million new cases and 380,000 deaths per year. A large number of patients are diagnosed with locally advanced disease and require multimodal treatment approaches. Despite advances in radiation and surgical techniques and the use of chemotherapy and monoclonal antibodies in advanced disease, more than half of all patients recur. Tumor cells from various solid malignancies, including HNSCC, over-express PD-LI to habituate the immune checkpoint pathways to evade immune surveillance. In this review, we summarize the current literature on immunotherapeutic options that are available for HNSCC patients.

Carotid body tumors are rare neuroendocrine tumors derived from the extra-adrenal paraganglioma of the autonomic nervous system. Very few cases have been reported in literature in the pediatric age group <14 years of age. We present our experience in managing a Shamblin III carotid body tumor in a 13-year-old boy who underwent an unsuccessful attempt at excision at another hospital. Surgical excision of the tumor along with ligation of the internal carotid artery was done without any postoperative neurological sequel. The tumor on the contralateral side was being managed conservatively with serial follow-up.

Carcinoma cuniculatum is a distinct but rare subtype of squamous cell carcinoma, often creating a diagnostic dilemma. Although it is associated with a good prognosis, it is locally aggressive and requires complete treatment. Distinguishing it from similar conditions is crucial to its management. We present our experience of two cases of carcinoma cuniculatum of the oral cavity and a review of literature.

DOI
:10.4103/jhnps.jhnps_33_19
Lemierre's syndrome is an infectious thrombophlebitis of internal jugular vein (IJV) which occurs rarely, as a complication of oropharyngeal infection. We report an unusual case of a 36-year-old healthy female who presented with high-grade fever with chills, sore throat, and diffuse swelling of the neck on the right side. Examination revealed pharyngitis with swelling on the neck on the right side with palpable submental and submandibular lymph nodes bilaterally. Local site ultrasonography revealed thrombosed right IJV with subcentimetric regional lymph nodal enlargement. She was started on prophylactic intravenous antibiotics and anticoagulants, awaiting blood culture report. A detailed workup was done to rule out occult malignancy, and autoimmune as well as thrombotic screening was also negative. The etiological agent could not be identified as blood cultures were negative; she had already received antibiotics prior to admission. She responded to treatment, and there were no metastatic complications. Though the syndrome is rare, it has severe manifestations and mortality can be reduced, if timely diagnosed and managed.

Intrathyroidal parathyroid (IP) adenoma as a cause of primary hyperparathyroidism (PHPT) presents a diagnostic challenge in localization and differentiating it from a thyroid nodule. We report here three distinct cases of PHPT where preoperative imaging findings were compared with surgical and histopathological findings. Case 1 was a typical true IP adenoma, as diagnosed by preoperative sestamibi and ultrasound, and confirmed at surgery and subsequent histopathology. Case 2 was diagnosed by sestamibi and ultrasound as bilateral lower pole IP adenomas which turned out to be thyroid nodules at surgery. Postsurgery, the serum PTH levels dropped only partially and PHPT persisted. Revision surgery was performed, and a right inferior parathyroid adenoma was removed, after which PTH was normalized. Case 3 had a preoperative sestamibi diagnosis of left inferior parathyroid. Preoperative ultrasound suggested a left thyroid nodule/IP along with an associated contralateral right inferior parathyroid nodule. Surgery and subsequent histopathology confirmed left follicular adenoma and right inferior parathyroid adenoma. We discuss the limitations of preoperative imaging modalities in these cases along with their learning outcomes. It is very essential that all the involved clinicians, radiologists, and surgeons are well aware of the diagnostic features and pitfalls associated with IPs so as to enable a correct diagnosis and appropriate surgical or medical management.
