UNASSIGNED: Magnetic resonance imaging (MRI) is a routinely used imaging modality for pre-treatment radiologic evaluation of tongue carcinoma, providing accurate information regarding the extent of the disease.
UNASSIGNED: To investigate the role of MRI-derived depth of invasion and tumor thickness evaluation in squamous cell carcinoma of the tongue, and to assess if any correlation exists between depth of invasion, tumor thickness, nodal metastasis, muscles, and space involved.
UNASSIGNED: Thirty-three patients with oral squamous cell carcinoma of the tongue who had undergone pre-treatment MRI and excisional biopsy were included. The tumor thickness (TT) and depth of invasion (DOI) were evaluated on MRI and histopathologic images.
UNASSIGNED: The relation between different methodologies for assessing showed a very high correlation for the tumor tissue thickness (r = 0.99, p < 0.05) and depth of invasion (r = 0.82, p < 0.05). The tumor thickness and the depth of invasion increased with the loss of differentiation in the carcinoma histopathologically. As the depth of invasion increases, the extent of the spread of the carcinoma to tongue musculature, lingual septum, and spaces also increases.
UNASSIGNED: The present study has depicted a high correlation between the tumor thickness and the depth of invasion between MRI and histopathological findings and is the first of its kind to correlate DOI to the invasiveness of the disease.

Patients with long-standing autoimmune diseases like systemic lupus erythematosus (SLE) are at a higher risk of developing hematological malignancies. However, chronic myeloid leukemia (CML) has rarely been reported in patients with SLE. Advancements in medical diagnostics and treatment have led to the life expectancy of SLE and CML patients moving closer to that of the general population, and it is not uncommon to encounter more than one malignancy in a cancer survivor. Although squamous cell carcinoma (SCC) of the skin has been reported in CML patients, mucosal SCC of the head and neck has rarely only been reported in CML survivors. The objective of this case report is to share our experience in treating a patient with dual metachronous primary malignancies, CML, and tongue carcinoma, along with long-standing SLE, managed by a multidisciplinary team.

Squamous cell carcinoma is the most predominant type of malignancy in the head and neck region with neuroendocrine carcinomas (NECs) being a rare occurrence. Here we report a rare case of small cell non-keratinizing NEC (WHO grade 3), TNM (tumor, node, and metastasis) stage T3N1M0, involving the larynx and the base of the tongue, in a 54-year-old male patient, demonstrating its rarity in an uncommon anatomical site and an aggressive and relatively uncommon pattern of spread for this tumor, over a period of two months. NECs in the head and neck region, especially those affecting the larynx and the posterior third of the tongue, remain exceedingly rare, comprising only a small fraction of malignancies in this region. The aggressive nature and distinct pattern of spread observed in this case underscore the importance of recognizing such unusual presentations for appropriate diagnosis and management. Given the rarity of this tumor type, a comprehensive understanding of its clinicopathological features is essential for guiding effective treatment strategies. We also discuss the treatment.

To compare postoperative complications, functional rehabilitation, surgical outcomes of the radial artery forearm free flap (RAFFF) and split thickness skin graft (STSG) reconstruction of postsurgical defect in T2 lesions of cancer oral cavity. Observational Prospective comparative study. Academic tertiary referral centre. In our study of forty four patients, after tumour resection, half underwent reconstruction using RAFFF (Group I) and another half by STSG (Group II). All of the patients were followed postoperatively to determine and compare their functional outcomes related to donor site and recipient site complications, speech, deglutition and mouth opening. The speech intelligibility and deglutition were each assessed using Articulation Handicap Index and Vedio-fluoroscopy using the Functional oral intake scale. Operative time for STSG reconstruction was shorter at 2.2 ± 0.97 SD hours compared to 5.9 ± 1.24 SD hours for RAFFF reconstruction. Hospital stay was 8.3 ± 1.19 SD days for STSG patients and 12.6 ± 1.7 SD days for RAFFF patients. The functional outcomes of speech quality and swallowing were near comparable in both groups but the donor site complications were significant in the RAFFF group. Operative time, hospital stay and donor site complications are both significantly reduced with the STSG as opposed to RAFF. Functional and oncologic results of both methods are near comparable. To conclude, STSG can be used for reconstruction of the post-surgical defects in T2 lesions of the tongue.

Differential diagnosis of neuropsychiatric symptoms in a patient with an underlying malignancy is exhaustive. 5-fluorouracil (5-FU) is one of the most widely used chemotherapy agents and it is often used as the first-line regimen in head and neck malignancies. We present a case of an elderly female with an underlying locally advanced p16-positive squamous cell carcinoma of the tongue who presented with manic symptoms for one week after cycle 2 of chemotherapy. Multidisciplinary management by otorhinolaryngologists with psychiatrist and oncologist led to the cessation of 5-FU, administration of antipsychotics, and replacement with a different chemotherapy agent, leading to complete resolution of manic symptoms. Possible mechanisms of the 5-FU-induced manic episode with its treatment are discussed in this report.

UNASSIGNED: To analyze the results of patients treated with perioperative interstitial brachytherapy (ISBT) in tongue carcinoma (TC).
UNASSIGNED: From April 2009 to May 2015, 43 squamous cell carcinoma consecutive patients diagnosed with TC were treated with limited partial glossectomy and perioperative ISBT, using high-dose-rate (HDR). Twenty- seven patients were treated by brachytherapy (BT), and sixteen received BT as a complement to subsequent external beam radiotherapy (EBRT) after results of lymph node dissection. Median age was 66 years. Distribution by stage, included 10 patients stage I, 14 stage II, 10 stage III, and 9 stage IV. Eighteen patients had negative margins, nineteen margin involvement, and in six cases, the margin was < 5 mm.
UNASSIGNED: With a median follow-up of 54 months, LC at 3 and 5 years was 87% and 84%, respectively. LC was 95% at five years in patients with clear margins, and 75% with involved margins. LC in N0 patients treated with BT was 83% at 5 years, and in patients N+ with posterior EBRT treatment, LC was 86%. By tumor size, we found one local relapse in 13 cases T1, in 5 of 27 patients T2 was found, and no local relapse T3 with LC of 87%, 70%, and 100% respectively at five years. Regional control (RC) was 81% at 3 and 5 years. We found a metastasis-free survival of 91% at 3- and 5-year. Twenty-three patients have died, 11 of them due to other causes, with overall survival of 56% at three years and 53% at five years.
UNASSIGNED: Combined treatment with conservative surgery and ISBT shows similar results to radical surgery or RT alone, allowing a more patient-tailored approach, with good organ function preservation and cosmetic outcomes.

Chyle leaks after a neck dissection usually manifest within the immediate postoperative period. However, masked chyle leaks may present as a chyloma months later. A 54-year-old male patient with squamous cell carcinoma of the tongue underwent bilateral neck dissection, subtotal glossectomy, anterolateral thigh flap reconstruction and postoperative radiotherapy. Intraoperatively, chyle leak was encountered in level IV of the left neck. We managed it by ligation of the thoracic duct, application of Tisseel™ sealant (Baxter Inc., Illinois, USA) and one week of prophylactic fat-free feeds. Six months later, an asymptomatic chyloma of the left neck was identified on surveillance MRI. Five weeks after the diagnosis, streptococcal infection developed within the chyloma. However, initiation of fat-free diet, serial aspiration, pressure dressing and antibiotic therapy allowed the chyloma to resolve within two weeks. Further surveillance MRI over three years showed no recurrence of the chyloma. Low-volume chyle leaks may manifest as an occult chyloma. Prophylactic measures cannot replace meticulous ligation of chylous channels in left level IV neck dissection.

A 32-year-old habitual tobacco chewer was diagnosed with squamous cell carcinoma of the tongue. He was initiated on chemo-radiation therapy. After completing 23 cycles of radiation and four cycles of cisplatin-based chemotherapy, he presented with acute nephritic syndrome. Renal biopsy showed IgA nephropathy and acute tubular injury. With supportive care, renal function stabilised with a reduction in proteinuria. We wish to highlight the poorly understood association between mucosal malignancies and IgA nephropathy. It is also interesting to note the peculiar temporal profile of glomerular involvement in our patient, where the onset of the glomerulonephritis was after the initiation of chemo-radiotherapy. This is unlike what has been described earlier.

OBJECTIVE: This study aimed to clarify the accuracy of intraoral ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) in preoperative image depth of invasion (DOI) measurement of T1/T2 tongue cancer through comparison with histopathological measurements.
METHODS: Imaging of the primary lesions was performed at our hospital; the lesions were classified into T1 and T2 based on the 8th edition of the AJCC/UICC, and surgery performed. There was histopathological confirmation of lesions as squamous cell carcinoma in 48 patients with tongue cancer. T3 and T4 cases, cases in which preoperative chemotherapy and radiation therapy were performed, and cases where biopsy was performed before imaging were excluded. The radiological DOI in US, CT, and MRI and the histopathological DOI as base were comparatively investigated and statistical analyses were performed by Bland-Altman analysis and Spearman\'s rank correlation coefficient.
RESULTS: Bland-Altman analysis showed that the US radiological DOI was overestimated by an average of 0.2 mm compared to the histopathological DOI, while CT and MRI radiological DOI were overestimated by an average of 2-3 mm. The comparison of CT and MRI revealed that the difference between the MRI and histopathological DOI, as well as the 95% limit of agreement, were smaller than those of the CT radiological DOI.
CONCLUSIONS: US is the most accurate preoperative diagnostic tool for T1 and T2 squamous cell carcinoma; CT and MRI tend to have an overestimation of about 2-3 mm and so caution is required.

OBJECTIVE: To carry out a meta-analysis of prospective literature comparing the clinical efficacy of elective neck dissection (END) vs observation (OBS) in patients with early-stage cT1/T2N0 tongue carcinoma.
UNASSIGNED: We systematically reviewed four databases from inception to 30-October-2020. We considered all studies meeting the following PICOS conditions: (a) Patients: early-stage cT1/T2N0 tongue carcinoma, (b) Intervention: END, (c) Comparator: OBS, (d) Outcomes: local tongue recurrence, cervical nodal recurrence, disease-specific survival (DSS) rate, and disease-free survival (DFS) rate and (e) Study design: prospective reports. We pooled dichotomous data as relative risks (RRs) with 95% confidence intervals (CIs).
RESULTS: Four studies (one case-control study and three randomised controlled trials) met our inclusion criteria. There were 448 eligible patients (225 and 223 patients were treated with END and OBS, respectively). END significantly correlated with improved DSS rate (RR = 1.15, 95% CI: 1.04-1.27, P = .007). Nonetheless, there were no significant differences between END and OBS groups regarding the rates of local tongue recurrence (RR = 1.23, 95% CI: 0.50-3.03, P = .65), cervical nodal recurrence (RR = 0.45, 95% CI: 0.16-1.27, P = .13) and DFS rate (RR = 1.08, 95% CI: 0.91-1.27, P = .38). Pooled analysis for cervical nodal recurrence was heterogeneous, and sensitivity analysis revealed a significantly lower cervical nodal recurrence rate in favour of END group (RR = 0.30, 95% CI: 0.13-0.67, P = .004).
CONCLUSIONS: END correlated with a significant decrease in cervical nodal recurrence and improved DSS rate. END might be superior to OBS in patients with early-stage cT1/T2N0 tongue cancer.
