Observational Study to Determine the Involvement of Level III Lymph Nodes in Case of Clinically Positive Level II Nodes in Carcinoma Breast.

Management of breast cancer has gradually shifted from era of radical surgery to present days of multimodality management and conservatism. Management of carcinoma breast is primarily multimodality of which surgery is one of the important roles to play. Our study is a prospective observational study to determine the involvement of level III axillary lymph nodes in clinically involved axilla with grossly involved lower-level axillary nodes. Underestimation of a number of involved nodes at level III shall result in inaccuracy of subset risk stratification leading to substandard prognostication. The enigma of not addressing presumably involved nodes thereby altering the staging vs acquired morbidity has always been a contentious issue. Mean lymph node harvest at the lower level (I and II) was 17.9 ± 6.3 (range: 6-32) while positive lower-level axillary lymph node involvement was 6.5 ± 6.5 (range: 1-27). The mean ± SD for level III positive lymph node involvement was 1.46 ± 1.69 (range: 0-8). Our prospective observational study though limited by the number and years of follow-up has demonstrated that the presence of more than three positive LN at a lower level increases the risk for higher nodal involvement substantially. It is also evident in our study that PNI, ECE, and LVI increased the probability of stage up-gradation. LVI was found to be a significant prognostic factor for apical LN involvement in multivariate analysis. On multivariate logistic regression > 3 pathological positive lymph nodes at the level I and II and LVI involvement elevated the risk of involvement at level III by 11 and 46 times, respectively. It is recommended that patients who have a positive pathological surrogate marker of aggressiveness should be evaluated perioperatively for level III involvement, especially in the setting of visible grossly involved nodes. The patient should be counseled and informed decision to perform complete axillary lymph node dissection with the added risk of morbidity should be contemplated.

Association of tobacco exposure with demographic and clinicopathological factors in patients of oral squamous cell carcinoma - A single-center experience.

INTRODUCTION: Almost a third of the global load of oral squamous cell carcinoma (OSCC) occurs in India and can be attributed to the widespread use of tobacco and tobacco-related products in this part of the sub-continent. MATERIALS AND METHODS: Records of 274 patients of OSCC treated between January 2018 and December 2019 in our institute were analyzed for the study for history of tobacco abuse and distribution of associated demographic, clinical, and pathological factors. RESULTS: The age of the patients in the study ranged from 31 to 82 years with a median age of 60 years. The ratio of oral cancer in males: females was 3:1. Exposure to tobacco was seen in the majority of patients (89%) who reported with oral carcinoma. Smokeless tobacco in the form of gutka was the most common abused tobacco, followed by bidi in our study. Tongue and buccal mucosa (38% and 36%, respectively) were the most common sites. Significant statistical correlation of tobacco use was seen with age, gender, clinical, and pathological tumor stages. CONCLUSION: With tobacco being the main cause of OSCC, further studies with a larger number of patients and preferably with a comparison arm of non-tobacco OSCC would help in elucidating the exact clinical and statistical correlation of tobacco with the clinicopathological factors.

Surgical and Functional Outcomes of En Bloc Resection of Sacral Chordoma: a Retrospective Analysis.

Conventional chordomas occur most commonly in the sacral region. Currently, wide local excision remains the only hope for a cure in this disease. However, given the substantial morbidity caused by sacrectomy, a delicate balance needs to be established. This study elaborates our experience in managing these complicated cases with the help of a multidisciplinary team approach and outlines the various surgical and functional outcomes of sacrectomy. This was a retrospective observational study. Ten cases of biopsy proven sacral chordoma underwent en bloc resection by a posterior approach from 2011 to 2018 after multidisciplinary evaluation. Data collected and analyzed included demographics, extent of the disease, and operative parameters such as operative time, estimated blood loss, level of vertebral resection, level and number of the most caudal nerve roots preserved, surgical margins, soft tissue, or spinal reconstruction. Postoperative outcomes included time to recurrence and neurological function at 1 year. Mean size of the tumor was 116.1 mm. Three (30%) patients had positive margins. The median time to recurrence was 32 months. Four patients eventually succumbed to the disease due to local or distant recurrence. Bladder and bowel functions were excellent in those with preserved S3. Two patients remained wheelchair bound; the rest were able to walk with or without support. Management of sacral chordoma remains an onerous journey for both the treating surgeon and the patient. A multidisciplinary team approach, with careful preservation of sacral nerve roots, negative surgical margins, and excellent postoperative rehabilitation, can achieve optimum results.

Congenital nasopharyngeal teratoma causing airway obstruction in the newborn.

Teratomas are the most common congenital tumors, but teratomas of the nasopharynx are rare in neonates. The present report is about an 18-day-old girl child with a nasopharyngeal teratoma protruding from the oral cavity. The tumor almost completely obstructed the airways and necessitated immediate intervention. The tumor was successfully removed by the transpalatal route. Histological examination showed that it was a mature teratoma. The case with its related differential diagnosis is discussed here.
