ABSTRACT

Objective: The objective of this study is to evaluate the diagnostic and prognostic ability of fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) scan in patients with squamous cell carcinoma of the head and neck treated with chemoradiotherapy or radiotherapy only. Materials and Methods: Fifty-nine patients with HNSCC planned for radical nonsurgical treatment were randomized to receive either three-dimensional conformal radiotherapy or intensity-modulated radiation therapy. In addition to routine clinical examination and staging investigations, patients had a FDG PET-CT scan at baseline and on the first follow-up for response assessment. No evidence of clinicopathological disease for at least 6 months after the completion of treatment was considered confirmation of complete response. The presence or absence of disease during the follow-up period was used to calculate the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of PET-CT for the primary site and node. Results: At a median follow-up of 52.5 months, 55.6% of patients were alive and disease free. Response assessment PET-CT was done at a median of 9 weeks (range: 5–18 weeks). PET-CT assessment of the primary had sensitivity, specificity, PPV, and NPV of 81.8%, 93%, 75%, and 95.2%, respectively; the corresponding figures at the node were 44.4%, 95.6%, 66.7%, and 89.6%. The median baseline maximum standardized uptake value (SUVmax) at primary and node was 14.9 and 8.1, respectively. When PET-CT was done after 10 weeks, no false-positive or false-negative findings were seen. Patients with negative PET at the first follow-up had a significantly better progression-free and overall survival. Conclusions: Disease evaluation using PET-CT has an overall accuracy of 80%. High baseline SUVmax correlates with worse clinical outcomes. Negative PET-CT at the first follow-up is a predictor for survival.

ABSTRACT

ntroduction: Primary bone and soft tissue sarcomas are rare, but diagnostically and therapeutically challenging group of tumors, requiring multidisciplinary management. There are limited documented studies from multidisciplinary teams , in the form of comprehensive analysis of these tumors, from our country. This study is an analysis of cases of osteosarcomas, Ewing sarcomas (ESs), chondrosarcomas (CSs), and soft-tissue sarcomas (STSs), registered at our institution during 2012. Methods: Clinical details, including outcomes of cases of bone and STSs, during the year 2012, were retrieved from the medical records of our institution and were further analyzed. Results: Ninety-five high-grade, extremity-based, treatment-naïve cases of osteosarcomas were treated with a novel, dose-dense, nonhigh-dose methotrexate-based OGS-12 protocol. Good histopathologic response (necrosis ≥90%) was achieved in 59% nonmetastatic and 56% metastatic patients. At a median follow-up of 48 months, the estimated 5-year event-free survival and overall survival (OS) were 67% and 78%, respectively. In the metastatic cohort at a median follow-up of 51 months, the 5-year estimated progression-free survival was 24% and OS was 26%. Among 87 (73.2%) nonmetastatic and 32 (26.8%) metastatic, analyzable cases of ES, at a median follow-up of 40 months, the disease-free survival (DFS) and OS in the nonmetastatic group were 62% and 83%; in the metastatic group, they were 37.5% and 65.6%, respectively. Among 40 cases of CSs (33 nonmetastatic and 7 metastatic), 21 had limb salvage surgery while 5 had amputation. Microscopically, 90.4% were Grade II CSs. Five-year OS and DFS were 84.6% and 71%, respectively. Among 189 high-grade, extremity-based STSs (89% nonmetastatic), synovial sarcoma was the most common subtype (31%). Eighty-five percent had limb preservation surgery; a majority were offered adjuvant radiation with or without chemotherapy. At a median follow-up of 51 (1–63) months, 3-year local control, DFS, and OS were 81%, 48%, and 64%, respectively. Conclusions: The novel OGS 12 and Ewing Family of Tumors 2001 protocols have shown comparable outcomes to international standards in cases of osteosarcoma and ES, respectively, and merit wider applications, especially in low- and middle-income countries (LMICs). Outcomes in STS and CSs were also comparable and underscore the importance of a multidisciplinary approach for the management of sarcomas in LMICS.

ABSTRACT

Background and Objectives: Salivary gland neoplasms are relatively uncommon. They have a wide variety of histopathological types with diverse biological behavior. It involves all the major and minor salivary glands in the head and neck. This article focuses on the various types of major salivary gland tumors treated at a tertiary cancer center along with their surgical morbidities and outcomes. Materials and Methods: Data of all the salivary gland neoplasms operated in the head and neck services between January 2012 and December 2013 were retrieved from a prospectively collected database. The clinical, demographic data and types of surgeries along with the morbidities were collated from the database and the details regarding the follow-up were collected from the electronic medical record. Results: Out of 235. cases registered, 107. patients were treated at our institute. The parotid gland was most commonly involved; majority were malignant lesions. Sixty-two patients were treatment naive at presentation. Majority presented with advanced disease. Superficial parotidectomy was the most common surgery performed and neck dissection was done in 27. patients. Facial nerve palsy was the most common complication following surgery. (16%). Sixty patients received adjuvant treatment. All patients on follow-up were alive at their last visit, with 10. patients having recurrence. Factors influencing the disease-free survival were extracapsular spread, tumor grade, and perineural invasion. Conclusion: The postoperative morbidities and outcomes for major salivary gland neoplasms in our series were acceptable and comparable to the results available in the literature. Appropriate treatment of the salivary gland neoplasm will yield good outcomes with acceptable morbidity.

ABSTRACT

Background: Confirmation of placement of Double lumen endobronchial tubes (DLETT) and bronchial blockers (BBs) with the pediatric fiberoptic bronchoscope (FOB) is the most preferred practice worldwide. Most centers possess standard adult FOBs, some, particularly in developing countries might not have access to the pediatric‑sized devices. We have evaluated the role of preintubation airway assessment using the former, measuring the distance from the incisors to the carina and from carina to the left and right upper lobe bronchus in deciding the depth of insertion of the lung isolation device. Methods: The study was a randomized, controlled, double‑blind trial consisting of 84 patients (all >18 years) undergoing thoracic surgery over a 12‑month period. In the study group (n = 38), measurements obtained during FOB with the adult bronchoscope decided the depth of insertion of the lung isolation device. In the control group (n = 46), DLETTs and BBs were placed blindly followed by clinical confirmation by auscultation. Selection of the type and size of the lung isolation device was at the discretion of the anesthesiologist conducting the case. In all cases, pediatric FOB was used to confirm accurate placement of devices. Results: Of 84 patients (DLETT used in 76 patients; BB used in 8 patients), preintubation airway measurements significantly improved the success rate of optimal placement of lung isolation device from 25% (11/44) to 50% (18/36) (P = 0.04). Our incidence of failed device placement at initial insertion was 4.7% (4/84). Incidence of malposition was 10% (8/80) with 4 cases in each group. The incidence of suboptimal placement was lower in the study group at 38.9% (14/36) versus 65.9% (29/44). Conclusions: Preintubation airway measurements with the adult FOB reduces airway manipulations and improves the success rate of optimal placement of DLETT and BB.
