Factors Associated With Postoperative Complications in Patients Who Underwent Parotidectomy: A Retrospective Study.

Objectives: This study aimed to determine the prevalence of complications after parotidectomy and identify factors associated with these complications. Methods: Data from patients who underwent parotidectomy for neoplasms in 2 tertiary centers were analyzed. Patient characteristics and postoperative complications were collected. Demographics, diabetes, and smoking status were evaluated using descriptive statistics. The prevalence of complications was determined and associations with smoking, surgical type, preoperative facial nerve involvement, final pathology, and Milan category were examined using chi-squared and correlation analyses. Results: Majority of patients were male (59.5%), falling within the age range of 31 to 50 years (42.7%). The most common complication was facial nerve weakness (23.6%), followed by seroma (19.1%), ear numbness (17.3%), and tumor recurrence (8.7%). Xerostomia demonstrated a correlation with smoking, while more invasive types of surgery showed associations with surgical site infection and tumor recurrence. Malignant disease on the final pathology and higher Milan category exhibited links with salivary fistula. No clear associations were found between preoperative facial nerve involvement and any of the complications. Age and body mass index (BMI) did not demonstrate significant correlations with complications. Conclusions: This study highlights the prevalence and associations of postparotidectomy complication. Facial nerve weakness was the most common followed by seroma and ear numbness. Smoking was correlated with xerostomia, while more invasive type of surgery was correlated with infection and recurrence. Age and BMI did not have associations. Personalized approaches and understanding factors for effective management are important. Further research is recommended to validate the outcome and understand the recovery from parotidectomy.

Papillary thyroid microcarcinoma with and without nodal metastasis: A comparative analysis.

OBJECTIVES: To assess the demographics and clinical factors of papillary thyroid microcarcinoma (PTMC) patients in Saudi Arabia and compared and analyzed the differences between the patients with and without lymph node metastasis (LNM). Papillary thyroid microcarcinoma (PTMC) is a common thyroid cancer and is not usually detectable clinically but found incidentally after pathologic evaluation of thyroid tissue following surgery for benign thyroid disorders. However, these tumors have a significant risk of LNM. METHODS: All PTMC patients who underwent surgery at King Abdulaziz University Hospital, King Fahad Medical City, and King Abdulaziz Medical City from 2012 to 2022 were included. The incidence rate of LNM was 9.17%. The patients' average age was 44.05. Most of the patients were female. RESULTS: Prevalence of LNM among PTMC patients is 9.17% (n=31). The PTMC patients showed the following significant risk factors for LNM: higher Bethesda class, type of pathology, extrathyroidal extension, extracapsular extension, lymphovascular invasion, and residual tumors in patients who had received radioactive iodine. Presence of thyroiditis, multifocality, goitrous thyroid, neural invasion, and tumor size were unrelated to the LNM in the PTMC patients. CONCLUSION: Higher Bethesda class, pathology type, extrathyroidal extension, extracapsular extension, lymphovascular invasion, and RAI-treated residual tumors were strongly linked to LNM.

Total Number of Identified Parathyroid Glands During Total Thyroidectomy and Its Relation to Postoperative Hypoparathyroidism.

OBJECTIVES: To evaluate the correlation between the intraoperative number of identified parathyroid glands (PGs) and the risk of developing hypoparathyroidism postoperatively. Also, to determine the risks and prognostic factors in patients with postoperative hypoparathyroidism. METHODS: A retrospective study of 499 patients who underwent total thyroidectomy at two tertiary care institutions, King Saud University Medical City (KSUMC) and King Fahad Medical City (KFMC) in Riyadh, Saudi Arabia was included. Individual demographic characteristics with detailed clinical information were recorded, focusing mainly on operative reports for a total number of identified PGs intraoperatively and investigating the risk of developing hypoparathyroidism postoperatively. Factors such as age, gender, comorbidity, and number of excised and reimplanted parathyroid glands were investigated to determine the risks and prognostic factors in patients with postoperative hypoparathyroidism. RESULTS: The findings from the analysis showed that the number of identified PGs intraoperatively had a positive correlation with a higher postoperative risk of developing hypoparathyroidism. For zero, one, two, three, and four identified PGs, the risk of hypoparathyroidism in one-hour parathyroid hormone level postoperative was 6.6%, 7.3%, 34.4%, 34.4%, and 17.2% respectively. CONCLUSION: The greater the number of identified PGs intraoperatively, the less likely it was to prevent inadvertent hypoparathyroidism post-total thyroidectomy.

Utility of the Milan System for Reporting Salivary Gland Cytopathology in Parotid Gland Masses: The Experience of Two Tertiary Centers.

Background The application of fine needle aspiration (FNA) in parotid masses via the Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) enhances the diagnosis of these lesions alongside radiological investigations.  Objectives Our objective was to assess the risk of malignancy, sensitivity, specificity, and false positive and negative results for each category of the MSRSGC. Additionally, we assessed the level of agreement between the FNA results using MSRSGC and post-resection histopathological diagnosis. Methods We conducted a retrospective chart review of parotid gland masses that received FNA and postoperative pathological diagnosis at King Saud University Medical City and King Fahad Medical City between 2018 and 2022. We summarized the categorical variables using frequencies and percentages. Results A total of 172 cases met the inclusion criteria. Males encompassed 102 patients (59.3%) of the study sample, and 89 (51.7%) of parotid masses were on the left side. The risk of malignancy for the MSRSGC categories was 37.5% (Category I), 9.0% (II), 50.0% (III), 4.7% (IVa), 50.0% (IVb), 100.0% (V), and 71.0% (VI). FNA had an overall success rate of 81%. The sensitivity was 64% and specificity was 94% for non-neoplastic masses. For benign masses, the sensitivity was 91% and specificity was 66%; however, the sensitivity was 40% and specificity was 97% for malignant lesions. We found that the percentage of agreement between the FNA and final pathology was 80%. Conclusion FNA using MSRSGC is a valuable preoperative clinical tool. However, the low sensitivity rates based on the diagnosis of malignant lesions should alert clinicians not to be overly reliant on biopsy results and instead defer to definitive surgical management.

Validity and Reliability of the Arabic Thyroidectomy-Related Voice and Symptom Questionnaire (A-TVSQ) for Assessing Post-Thyroidectomy Patients.

OBJECTIVE: Post-thyroidectomy patients commonly experience voice changes, swallowing symptoms, and neck discomfort, a condition known as post-thyroidectomy syndrome. The Thyroidectomy-Related Voice and Symptom Questionnaire (TVSQ) is a validated tool showing strong correlations with established tools with a potential predictive value for post-thyroidectomy voice outcomes. Our study aims to translate and validate the TVSQ into Arabic. METHODS: This validation study was conducted at King Abdulaziz University Hospital and King Khalid University Hospital in Riyadh, Saudi Arabia. Forward and backward translations ensured the conceptual equivalence of the Arabic TVSQ (A-TVSQ) and were reviewed by an expert panel. A pilot test assessed the A-TVSQ's face validity and clarity, leading to necessary cultural adjustments. The final A-TVSQ was preoperatively and postoperatively administered to thyroidectomy patients to evaluate its test-retest reliability. RESULTS: Data were collected from 116 participants (53 cases [45.6%] and 63 controls [54.3%]). The internal consistency analysis showed strong intercorrelation among the A-TVSQ items, with Cronbach's alpha coefficients (0.951) indicating excellent estimated internal consistency within both domains. Test-retest reliability showed a moderate level of reliability with an intraclass correlation coefficient of 0.696. A-TVSQ item discrimination analysis showed significant associations between the total and domain scores pre- and post-thyroidectomy. External validity analysis showed significant changes in A-TVSQ voice change (P < 0.010) and neck discomfort (P = 0.011) domains and total scores (P < 0.010) between before and 2 weeks after thyroidectomy. However, no significant changes were observed between 2 and 4 weeks after thyroidectomy. CONCLUSIONS: The translated and validated A-TVSQ showed excellent internal consistency and moderate test-retest reliability, comparable to the original version. Voice change significantly worsened after thyroidectomy, highlighting the need for continued monitoring and management strategies for this complication.

Patterns of treatment failure in patients with nasopharyngeal carcinoma and salvage treatment outcome: A retrospective analysis study.

INTRODUCTION: In Saudi Arabia, head and neck cancers represent 6 % of all malignancies. 33 % of these are nasopharyngeal. Thus, we aimed to distinguish patterns of treatment failure and salvage treatment outcomes among patients with nasopharyngeal carcinoma (NPC). METHODS: A retrospective review of patients treated for NPC in a tertiary care hospital. From May 2012 to January 2020, we retrospectively reviewed 175 patients that fit our inclusion criteria. Those who did not complete their treatment, started treatment in another institution, or did not complete a 3-year follow-up were excluded. In addition, the primary treatment outcome and the salvage treatment for those who failed initial treatment were collected and analyzed. RESULTS: Patients were predominantly stage 4 disease. 67 % of the patients were alive without evidence of disease during their last follow-up. However, 75 % of failure occurs in the first 20 months of completing the treatment regimen. Neoadjuvant therapy and delays in referral play a significant role in treatment failure. For failed cases, concurrent salvage chemoradiotherapy showed the best survival. CONCLUSION: Advanced stage 4A and T4 nasopharyngeal carcinoma should receive the maximum treatment, with a close follow-up, particularly during the first 2 years after treatment. Furthermore, the excellent outcome from salvage chemoradiotherapy and radiotherapy alone would make physicians aware of the importance of aggressive primary treatment.

Tranexamic acid in head and neck procedures: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: We conducted a meta-analysis of all randomized controlled trials (RCTs) that examined the benefits of tranexamic acid (TXA) among cancer patients undergoing head and neck (H&N) procedures. METHODS: We screened five databases from inception until 20 June 2021 and evaluated the risk of bias of the eligible studies. We pooled continuous outcomes using the weighted mean difference (WMD) with 95% confidence interval (CI). RESULTS: Five studies, comprising seven RCTs, met the inclusion criteria. This meta-analysis included a total of 540 patients; 265 and 275 patients were assigned to the TXA and control group, respectively. Overall, the included RCTs revealed a low risk of bias. The volume of postoperative bleeding was significantly lower in favor of the TXA group compared with the control group (n = 7 RCTs, WMD = - 51.33 ml, 95% CI [- 101.47 to - 1.2], p = 0.04). However, no significant difference was found between both groups regarding the volume of intraoperative bleeding (n = 6 RCTs, WMD = - 3.48 ml, 95% CI [- 17.11 to 10.15], p = 0.62), postoperative hemoglobin (n = 3 RCTs, WMD = 0.42 mg/dl, 95% CI [- 0.27 to 1.11], p = 0.23), duration of drainage tube removal (n = 4 RCTs, MD = - 0.41 days, 95% CI [- 1.14 to 0.32], p = 0.27), and operation time (n = 6 RCTs, WMD = 1.59 min, 95% CI [- 10.09 to 13.27], p = 0.79). TXA was safe and did not culminate in thromboembolic events or major coagulation derangements. CONCLUSION: TXA administration is safe and significantly reduces the volume of postoperative bleeding. However, no difference is identified between TXA and control groups regarding the volume of intraoperative bleeding, postoperative hemoglobin level, duration of drainage tube removal, and operation time.

Indications and Outcomes of Parotidectomy in Saudi Children: Experience From Two Tertiary Centers.

Introduction Children can present with a wide variety of parotid diseases. However, most of them do not require surgical treatment. The indications of parotid surgery in children may differ from those in adults. In this study, we aim to review the indications and outcomes of parotidectomy in our pediatric population. Methods Retrospective review of the medical records of patients who underwent parotid surgery at age <18 years in two tertiary centers over a 14-year period. Results A total of 18 parotidectomies were performed on 18 patients with a mean age of 13.5 years. All patients presented with a parotid mass. The most common procedure was superficial parotidectomy followed by total parotidectomy. Ten patients were diagnosed with a benign parotid disease (55.6%). The most common benign disease was pleomorphic adenoma. There were eight cases of parotid malignancy constituting 44.4% of all patients and 57% of patients presenting in the age range of 12-17 years. Mucoepidermoid carcinoma was the most common malignancy (six patients). Fine needle aspiration biopsy was performed in 12 children with a sensitivity, specificity, and overall accuracy of 62.5%, 50%, and 58.6%, respectively. The most common complication was temporary facial weakness (33.3%) which resolved in a mean time of 2.5 months. No disease recurrences were identified. Conclusions Parotidectomy is uncommon in the pediatric age group. Children with a solid parotid tumor have a higher risk of parotid malignancy when compared to adults. A parotid mass presenting in the second decade of life is more likely to be malignant than benign.

Lymph node yield as a prognostic factor in clinically node negative oral cavity squamous cell carcinoma.

OBJECTIVES: To determine the prognostic significance of nodal yield in patients with clinically node-negative (cN0) oral cavity squamous cell carcinoma (OCSCC). METHODS: This retrospective observational study included 40 patients with cN0 OCSCC who underwent treatment with at least 6 months of follow-up data from November 2012 to April 2020. We recorded the variables, including patient demographics, cancer site, tumor-node-metastasis (TNM) staging, type of treatment, lymph node yield (LNY), histopathologic diagnosis, and recurrence. The recorded data were analyzed with descriptive and interferential statistics using specific tests. RESULTS: Our study cohort comprised of 27 males and 13 females with a mean age of 60.08+13.153 years. Tongue (55%) was the commonly affected site. Seventeen (42.5%) patients belonged to TNM stage II. The mean LNY in our study was 38.65±25.41 (range 7-98). Following surgery, 19 (47.5%) patients further received adjuvant therapies. Recurrence was reported only in 4 (10%) patients. There was no significant difference between LNY and recurrence rate (p=0.892). Factors including, age (p=0.121), gender (p=0.209), site (p=0.519), size of tumor (p=0.416) did not influence the LNY. CONCLUSION: There is no correlation between LNY and recurrence in cN0 OCSCC patients in our study. Meticulous neck dissection and thorough pathologic reporting prevents TNM under staging and improves the overall survival and prognosis.

The Prevalence of Thyroid Papillary Microcarcinoma in Patients With Benign Thyroid Fine Needle Aspiration.

Introduction Thyroid nodules are a very common clinical finding in the general population. We use fine needle aspiration (FNA) as the gold standard workup test for a thyroid nodule, as it is capable of differentiating malignant nodules from benign in the majority of cases. Usually, FNA is done for nodules that are more than 1 cm; small malignant lesions that are less than 1 cm in size can be missed. That's why the risk of having undiagnosed microcarcinomas in an otherwise benign FNA needs to be explored. Aim To estimate the prevalence of thyroid papillary microcarcinoma in patients with benign FNA and evaluate and correlate the FNA cytological results with the final histopathological diagnoses. Methods This was a retrospective study of 1543 post-thyroidectomy patients who underwent FNA cytology, were classified according to the Bethesda scoring system, and were admitted to two tertiary care hospitals in Riyadh, Saudi Arabia, from 2010 to 2019. Results Six-hundred-seven (607) out of 1543 FNA cytology results were reported as benign, 215 as malignant, and 73 as suspicious of malignancy. On final histopathology diagnosis, 81/607 (13.34%) of benign cases and 35/215 (16.28%) of malignant cases did not meet the initial cytology and were confirmed as papillary microcarcinoma. In patients with microcarcinoma after initial benign FNA (89.2%) found to have benign multinodular changes, compared to only (31%) of initial malignant FNA patients. Conclusion  When non-surgical intervention is chosen in patients with benign FNA, the possibility of coexisting microcarcinoma with its variable prognosis should be taken into account and explained to the patient.

Seasonal variations in serum levels of vitamin D and other biochemical markers among KSA patients prior to thyroid surgery.

OBJECTIVES: Serum levels of vitamin D can vary between seasons, which may affect serum calcium levels in post-thyroidectomy patients. This study aimed to determine seasonal variations in serum levels of vitamin D and other biochemical markers in patients prior to thyroid surgery in a KSA hospital. METHODS: In this study, we analysed the data of 685 post-thyroidectomy patients. The preoperative laboratory values of all patients were collected, and the patients were categorized into groups based on the month when the surgical procedure was performed as follows: cold (November-February) and warm/hot groups (March-October). RESULTS: Serum vitamin D levels were deficient in 70% of the patients, insufficient in 18%, and optimal in 12%. The mean age of patients in the deficient group was significantly lower than that in the optimal group. There were significantly more patients who had vitamin D deficiency during the cold season than during the warm/hot season (p = 0.024). Serum vitamin D levels did not vary between seasons (p = 0.836); however, the preoperative magnesium and thyroid stimulating hormone (TSH) levels were significantly higher during the warm/hot season than during the cold season (p = 0.039 and p < 0.001, respectively). Preoperative calcium level was not significantly different between the cold and warm/hot months (p = 0.282). CONCLUSION: This study suggests a non-significant seasonal fluctuation in serum levels of vitamin D with insignificant variation in serum calcium levels during cold and warm/hot seasons. The findings necessitate a careful review of the patients' biochemical status prior to surgery. Future prospective longitudinal studies are needed to confirm this variability.

Serum levels of 25-hydroxy-vitamin D in patients with oral squamous cell carcinoma: Making a case for chemoprevention.

OBJECTIVES: Serum level of vitamin D has been used as a predictor for cancer development. We intend to measure the baseline vitamin D level in patients with oral squamous cell carcinoma (OSCC) and to compare same with non-cancer controls to determine any association. MATERIALS AND METHODS: Patients with OSCC presenting to our clinics were included in this study. Their baseline serum vitamin D levels were measured prior to cancer treatment after obtaining their consents. These patients were then matched with at least 2 cancer-free subjects to serve as controls and whose serum vitamin D levels were also measured. The serum vitamin D levels obtained for the two groups were then categorized into normal (>35 ng/ml), mild deficiency (25-35 ng/ml), moderate deficiency (12.5-25 ng/ml), and severe deficiency (<12.5 ng/ml). The data were analyzed statistically and the two groups compared. RESULTS: A total of 51 patients with OSCC (Male 22 [43%] and female 29 [57%]) and 113 cancer-free controls (Male 36 [31.86%] and female 77 [68.14%]) were included in the study. The commonest site for OSCC was the tongue, accounting for 45% of the cancer cases. Mean age for cancer patients was 59.33 years ±12.54 and 49.24 years ±15.79 for the control. Among the OSCC patients, 74.51% had moderate to severe vitamin D deficiencies, whereas only 20.35% had a moderate deficiency in the control group with no severe deficiency. CONCLUSION: Logistic regression analysis shows a positive association between vitamin D deficiency and OSCC risk especially in levels below 25 ng/ml. This further corroborates the assertion that vitamin D deficiency may be a useful indicator of OSCC. It may, therefore, be necessary to routinely prescribe vitamin D supplements to subjects with moderate to severe deficiencies in order to decrease the chances of OSCC development.

Predictors for Salivary Gland Cancer Recurrence at Two Tertiary Hospitals in Saudi Arabia.

Background Tumors of salivary glands are enlarged as a low-risk mass and mostly benign in nature. The treatment of salivary gland malignancy remains quite challenging because of its relative infrequency, unreliable biological manners, and risk of re-emergence. For effective treatment planning, prediction of factors associated with the recurrence of salivary gland malignancy is essential. Aim The objective of this study was to identify the factors associated with recurrence of salivary gland malignancy at two tertiary hospitals in Saudi Arabia. Material and methods A cross-sectional study was conducted at two tertiary hospitals in Saudi Arabia, where data of patients were recorded from the medical records of hospitals from 2012 to 2018. 63 patients who were diagnosed with salivary gland malignancy, whether originated from parotid, submandibular, sublingual, and minor salivary glands were included in the study. Descriptive statistics are shown in mean, frequency, and percentages, while comparative analysis was done using the Chi-square test, where p < 0.05 is considered significant. Results This study included 63 participants. The majority of malignant salivary gland cancers arise from the parotid gland (47.6%), and mucoepidermoid carcinoma was the commonest form of malignancy in 36.5% of the studied population. Out of 63 patients, 17 had a recurrence of cancer, and the initial advanced stage of the disease is apparently associated with the re-emergence of salivary gland cancer. Conclusion The initial advanced stage of cancer has a significant role in the recurrence of salivary gland malignancy. As salivary gland malignancy is rare and has unreliable behavior, establishing an adequate treatment plan prediction for recurrence is essential.

Translation and cultural adaptation of an Arabic version of the patient scar assessment scale for thyroidectomy patients.

OBJECTIVES: To translate and validate an Arabic version of the patient scar assessment scale (PSAS). The cosmetic appearance of a thyroidectomy scar can critically influence a patient's self-esteem. Moreover, scar evaluation tools are necessary for an evidence-based approach to scar management. METHODS: This  quantitative, observational, cross-sectional study was conducted by administering an Arabic-translated version of the PSAS. The translation process included a forward translation into Arabic by 3 fluently bilingual otolaryngologists, a back-translation into English, and a comparison with the original items. The questionnaires were distributed to patients who underwent thyroidectomies. We included patients who underwent surgery at least 2 months previously. RESULTS: A total of 50 patients were included in this research. The internal consistency was 0.89, with a 95% confidence interval (CI) of 0.88-0.90. The score distributions showed high correlations for all items. The Arabic-translated PSAS showed good test-retest reliability, and the Pearson correlation coefficient between the test and retest administrations was 0.84 (p<0.001). With a possible range of 6-60 points, the standard error of the mean was 5.14, and the minimal detectable change was 14.2. CONCLUSION: This Arabic version of the PSAS was reliable for use in Arabic-speaking communities. It will allow for comparisons between the results of investigations conducted in different countries, which aids in the exchange of information within the international scientific community.

Absence of human papillomavirus in oral cavity squamous cell carcinomas among Saudi patients.

This study aimed to examine the possible association of human papillomavirus (HPV) with oral cavity squamous cell carcinomas (OCSCCs) in Saudi Arabia. Forty-five paraffin-embedded tumor blocks that represent different subsets of OCSCCs between 2010 and 2014 were retrieved and histologically evaluated. The presence of high-risk HPV (16, 18, 31, and 33) was assessed by p16-immunohistochemistry followed by DNA detection using in situ hybridization technique. Twenty-four patients were male with the mean age of 59.3 years, and 21 patients were female with the mean age of 61.2 years. Forty-one cases were positive for p16 immunostaining, and the remaining four cases were negative. However, none of the 45 cases showed DNA-expression for any HPV subtypes (16, 18, 31, and 33). High-risk HPV appears not to be involved in the etiology of OCSCCs in older Saudi patients, but further studies with cross section of a younger age group are still required.

Risk Factors of Incidental Parathyroidecomy in Thyroid Surgery.

BACKGROUND: Incidental parathyroidectomy with subsequent hypoparathyroidism and postoperative hypocalcemia is thought to be one of the common complications of thyroidectomy. Current literature reports wide discrepancy in incidence and risk factors. OBJECTIVES: The aim of our study was to evaluate the incidence and risk factors of incidental parathyroidectomy in thyroid surgery. METHODS: A retrospective study included 270 patients who had thyroid surgery that was performed over two years from January 2017 to December 2018 in two tertiary care hospitals. Preoperative and postoperative records were assessed. Factors such as gender, diagnosis, type of surgery, and usage of surgical loupes during the procedure were evaluated and were compared to find the association with incidental parathyroidectomy in thyroid surgery. RESULTS: Incidental parathyroidectomy was noticed in 62 (23%) surgical specimens during histopathologic examination. There was no significant association between incidental parathyroidectomy and sex of patient, use of surgical loupes, pathology of thyroid disease, or neck dissection. CONCLUSION: Although the risk of incidental parathyroidectomy is inevitable, careful dissection and meticulous intraoperative identification of parathyroid gland during thyroidectomy can reduce the incidence of incidental parathyroidectomy, thereby minimizing the risk of postoperative hypoparathyroidism and hypocalcemia.

Outcomes of Early-stage Glottic Carcinoma Treated with Radiation Therapy: A Single Institution Experience.

OBJECTIVE:  To evaluate the outcomes of radical intent radiation therapy in early glottic carcinoma (EGC), including local control rate (LCR), disease-free survival (DFS), death specific free survival (DSFS), and overall survival (OS) rates, in Saudi patients treated at a single institution.  Materials and methods: This is an institutional review board (IRB) approved, retrospective study of 27 patients with T1-2 N0 M0, early glottic carcinoma (EGC) who were treated from 2010 to 2015 at our institution with different radiotherapy (RT) fractionation regimens. The regimens included six different fractionation schedules of radiotherapy (RT): 50 Gy (20 x 2.5 Gy) dose prescribed to 95% isodose line, 52.4 Gy (20 x 2.52 Gy), 63 Gy (28 x 2.25 Gy), 66 Gy (33 x 2 Gy), and 70 Gy (35 x 2 Gy). The cohort was stratified into two groups, ≤ 52.5 Gy (n=15) and > 52.5 Gy (n=12). The median follow-up of all patients was 31.7 months (range 7-82). RESULTS: The mean age of the cohort was 64.5 years (median 65, range: 41-83). Eleven patients (40.7%) had a history of smoking. The majority of the cohort was with T1a EGC (70.4%, n=19), and anterior commissure invasion was seen in three patients (11.1%). The mean RT doses were 55.6 Gy (range: 50-70). The five-year LCR, DFS, DSFS, and OS rates were 83.1%, 80.0%, 96.2%, and 92.6%, respectively. The LCR rates for those receiving a dose of 52.5 Gy or less were 61.3 months compared to 89.5 months for those who received more than 52.5 Gy (p=0.994). Non-smokers and patients with an unknown smoking history achieved a five-year LCR of 100%, while patients with a positive smoking history achieved a five-year LCR of 60.6% (p=0.044). CONCLUSION:  Radiation therapy for EGC in our patients showed reasonable five-year LCR with larynx preservation at 83.1%, DFS 80.0%, five-year OS rate 92.6%, and DSFS rate 96.2%. We found that smoking had a significant correlation with LCR. However, large prospective trials are warranted to evaluate the efficacy of overall treatment time, dose per fraction of above 2 Gy, and smoking effect.

Development and validation of Arabic version of the Short-Form McGill Pain Questionnaire.

INTRODUCTION: The Short-Form McGill Pain Questionnaire (SF-MPQ) is a widely used tool for qualitative and quantitative pain assessment. Our aim was to translate, culturally adapt, and validate the SF-MPQ in Arabic. METHODS: A systematic translation process was used to translate the original English SF-MPQ into Arabic. After the pilot study, we validated our version in patients with chronic pain at two tertiary care centers. We tested the reliability of our version using internal consistency and test-retest reliability. We examined the validity by assessing construct validity, concurrent validity (by investigating the associations between SF-MPQ, Brief Pain Inventory [BPI], and Self-completed Leeds Assessment of Neuropathic Symptoms and Signs [S-LANSS]), and face validity. The questionnaire was administered twice to examine responsiveness. RESULTS: A total of 142 participants (68 men and 74 women) were included in this study. Cronbach's α was 0.85 (95% confidence interval: 0.81 - 0.89), and interclass correlation coefficients were 0.71 (0.62-0.79) for the whole scale. SF-MPQ was moderately associated with patients' present pain (r = 0.55, P < 0.001) and the numerical rating scale (r = 0.42, P < 0.001). The total pain score was moderately correlated with pain severity and interference assessed with the BPI (rs = 0.39 to 0.49, all Ps < 0.001). SF-MPQ total pain score was weakly associated with neuropathic pain assessed with S-LANSS (r = 0.26, P < 0.01). Most patients found the SF-MPQ questions to be clear and easy to understand and thought the questionnaire items covered all their problem areas regarding their pain. CONCLUSION: Our translated version of SF-MPQ was reliable and valid for use among Arabic-speaking patients. The SF-MPQ is a good qualitative and quantitative assessment tool for pain but is only weakly associated with neuropathic pain.

The burden of chronic pain after major head and neck tumor therapy.

INTRODUCTION: Little is known about the burden of chronic pain after major head and neck tumors' therapy. In this study, we aimed to estimate the prevalence of chronic pain, explore the factors associated with the presence of chronic pain, and assess the consequences of chronic pain on the patients' quality of life. METHODOLOGY: This was a cross-sectional survey among patients who had completed their therapy (e.g., surgery, radiotherapy, and chemotherapy) for major head and neck (larynx, nasopharynx, oropharynx, hypopharynx, oral cavity, tongue, and sinuses) tumors after at least 3 months. We collected relevant demographic and clinical data and administered the Brief Pain Inventory-Short Form, Neuropathic Pain Questionnaire-Short Form, and Pain Catastrophizing Scale questionnaires. Possible risk factors were explored using a classification tree model. RESULTS: A total of 102 patients (59 men, 42 women) were enrolled in this study between 3 and 72 months after tumor treatment. 30% of the patients reported having chronic pain after their major head and neck tumors' therapy. The average pain score in the last 24-hr was 3.4 (standard deviation = 2.7). The prevalence of patients with chronic pain was higher (42%) among those who had surgery. Factors associated with chronic pain were female sex, older age, surgery, advanced cancer stage, and radiotherapy. Patients who reported having chronic pain also reported having a lower quality of life manifested by impairments in general activity, mood, walking ability, normal work, and sleeping. Patients who reported having chronic pain had higher Pain Catastrophizing Scale scores. CONCLUSION: Our study highlighted the high burden of chronic pain after therapy for major head and neck tumors. We identified demographic and clinical factors that are associated with the presence of chronic pain. Further studies are required to better understand the risk factors to implement strategies to prevent, alleviate, and treat chronic pain associated with major head and neck tumor therapies.

Large primary leiomyoma causing progressive cervical deformity.

Leiomyomas are benign smooth tumors that rarely affect the neck area. Complete surgical resection is the treatment of choice. Here, we describe a 13-year-old girl with a large leiomyoma of the neck, which increased in size after incomplete resection. The tumor caused progressive cervical kyphotic deformity, difficulty breathing and severe malnourishment. The tumor was resected successfully in a second surgery, and the patient is stable after 3 years of follow-up. Histopathologically, the tumor was consistent with leiomyoma and showed strong reactivity to specific smooth muscle markers, such as desmin and caldesmon. This is the second reported case demonstrating massive growth of a leiomyoma, with emphasis on complete resection from the beginning.
