Background: As head and neck cancer (HNC) affects regions directly related to the digestive tract, it is consistently associated with nutritional impact symptoms (NISs), which further reduce food intake and affect nutritional status. Early identification of patients with NIS can assist therapy. Method: This is a cross-sectional study with HNC patients from a cancer reference hospital. Sociodemographic, lifestyle, clinical, and anthropometric data were collected, along with information on nutritional risk screening and screening for NIS. Results: Cancer in the larynx (p=0.031) showed a 6.67 lower NIS score than that in the oral cavity. Ex-smokers (p=0.019) showed a 5.87 lower NIS score and nutritional risk (p=0.009) increased NIS scores by 6.15 points. Conclusion: Tumor location, smoking, and the presence of nutritional risk influence the quantity and severity of NIS.

Background and Aim: Esophageal cancer is the sixth most common cancer in India with a incidence of around 4.5%. Dysphagia is the primary manifestation of advanced esophageal cancer in 80%-90% of patients. Dysphagia is one of the most distressing and debilitating symptom for the patients. The use of self-expanding metallic stents (SEMS) has revolutionized the treatment of dysphagia in esophageal cancer patients. This study aims to assess the role of SEMS in the palliation of dysphagia in patients with esophageal cancer. Methods: This was a single-center, prospective observational study conducted in the Department of Surgical Oncology at Dr. B. Borooah Cancer Institute in Guwahati, India, from April 2019 to March 2020. Patients were assessed after stent placement for improvements in dysphagia, pain relief, nutritional status, and associated complications. Results: One week after stent placement, 65.3% of patients were able to tolerate semisolid food and 6.1% could tolerate solids. Prior to stent insertion, 87.8% had Grade 4 dysphagia, but at 6 months post-SEMS placement, 90.2% had only Grade 1 dysphagia. This represented a statistically significant improvement in the dysphagia grade, with a p value less than 0.0001. Further analysis using ANOVA and paired t-tests showed significant improvements in weight, body mass index (BMI), and serum albumin at 1, 3, and 6 months after stent placement, with p values less than 0.001. Conclusion: The results of this study demonstrated that the placement of SEMS is a safe and effective palliative intervention for management of dysphagia in carcinoma esophagus, leading to improvements in patient nutrition and quality of life, with relatively few associated complications.

This study sought to comprehensively evaluate the diagnosis, therapeutic interventions, and outcomes of individuals afflicted with malignant parotid tumors at a tertiary care otolaryngology department in Heilbronn, Germany, spanning the years 2010-2018. The primary objective was to juxtapose this dataset with findings from analogous single and multicenter investigations. We conducted a meticulous analysis of electronic medical records pertaining to 45 patients subjected to primary parotid cancer treatment. The male-to-female ratio was 3:2, with an average age of 61 years. Predominant histological types included mucoepidermoid and squamous cell carcinomas, with ultrasound emerging as the predominant diagnostic modality (97.8% sensitivity). Intraoperative frozen sections exhibited a high level of sensitivity. Notably, lymph node metastasis was prevalent in T3 tumors, frequently located intraparotid and at Neck level II. Solely one patient exhibited distant metastases (pulmonary). All patients underwent parotidectomy, and 29% necessitated a secondary procedure due to positive resection margins. Postoperative complications encompassed facial nerve palsy, seromas, and salivary fistulas. Adjuvant radiotherapy (38%) was recommended for high-grade tumors, T3/T4 stage, N+, perineural invasion (PNI), and positive or uncertain surgical margins. Neck dissection was executed in 67% of instances, with 20% revealing occult lymph node metastases. Recurrence manifested in 22% of patients, primarily as locoregional recurrence (80%) and distant metastases (20%). The 3-year recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) rates stood at 72.1%, 91.9%, and 87.5%, respectively. Noteworthy factors influencing RFS included preoperative facial palsy, T stage, resection margins, and PNI. In summary, the management of parotid cancer involving surgical interventions, neck dissection, and radiotherapy in high-risk patients yielded commendable outcomes with minimal complications, showcasing survival rates exceeding 70%. Timely diagnosis at an early stage is imperative for achieving tumor-free margins and enhancing survival rates. More assertive therapeutic strategies are advocated for cases presenting with preoperative facial nerve palsy and PNI.

Background and Objectives: This study aims to translate and culturally adapt the Toronto Extremity Salvage Score (TESS) for Latin American Spanish-speaking patients, enhancing the tool's accessibility for evaluating postsurgical functional outcomes in sarcoma patients across Latin America. Methods: The TESS questionnaires for lower extremity (LE) and upper extremity (UE) were translated and adapted following international guidelines. The process included forward and backward translation, expert committee review, and pretesting with cognitive interviewing. Patients treated for bone or soft tissue tumors in LE or UE were recruited to complete the adapted questionnaires. Test-retest reliability was evaluated by having participants complete the questionnaire again 2 weeks after the initial assessment. Results: A total of 89 participants completed the questionnaires. The study found high internal consistency, with Cronbach's alpha values reaching 0.9437 for LE and 0.9402 for UE. An agreement rate of 98.4% for the global score of TESS-LE (95% confidence interval [CI]: 0.909-1.059) and 93.9% for TESS-UE (95% CI: 0.882-0.995) was observed, demonstrating strong test-retest reliability. Conclusions: The Latin American Spanish version of TESS for both lower and upper extremities is a reliable and culturally appropriate tool for assessing physical function in limb sarcoma patients. Further validation across diverse Latin American populations is encouraged to strengthen its broad applicability.

Background: Following ablative surgery, the reconstruction of oral cavity defects is essential to ensure optimal function and aesthetically acceptable outcomes. The purpose of this study was to retrospectively analyze the effectiveness and complication rates of the sublingual gland flap (SGF) in oral soft tissue reconstruction. The procedure for harvesting SGF and the strengths and limitations of the flap are discussed. Materials and Methods: The study group consisted of 13 patients suffering from oncological diseases who underwent soft tissue reconstruction with SGF. The patient's medical charts were evaluated based on histopathological aspects, postoperative complications, and outcomes. Reconstruction of the floor of the mouth was performed in 8 patients (61.5%) and lower gingiva in 5 patients (38.5%), respectively. Results: Complete epithelialization with closure of the defect was achieved within an average of 2 weeks. The observation period ranged from 1 to 33 months, with an average duration of 11.5 months. Partial flap necrosis and ranula occurred in one patient (7.7%). Furthermore, postoperative bleeding was observed in one patient (7.7%), and wound dehiscence and abscess formation were noted in another (7.7%). Locoregional recurrence of the cancer was observed in one case (7.7%). Conclusions: The SGF is effective for achieving successful reconstruction of small- and medium-sized defects in the lower gingiva and floor of the mouth. The complication rate is relatively low.

Purpose: To evaluate the predictive potency of a novel index combining the pan-immune-inflammatory index and hemoglobin levels (PIV/Hb) for the prevalence of radiation-induced trismus (RIT) in patients with locally advanced nasopharyngeal cancer (LA-NPC) receiving concurrent chemoradiotherapy (CCRT).

Methods: Data from 228 LA-NPC patients were retrospectively examined. Maximum mouth openings (MMO) were measured to confirm the presence of RIT, defined as MMOs ≤35 mm. Complete blood test results from the first day of CCRT were used to calculate PIV/Hb levels. A potential relationship between pretreatment PIV/Hb and the RIT status was evaluated using receiver operating characteristic (ROC) curve analysis.

Results: Post-CCRT RIT was diagnosed in 20.2% of the patients. The ROC curve analysis determined 68.4 g/dL as the ideal PIV/Hb cutoff that effectively divided patients into two distinct groups (area under the curve: 94.7%; specificity: 86.4%; sensitivity: 87.4%). RIT was significantly more prevalent in the PIV/Hb > 68 group than in the PIV/Hb < 68 group (58.8% vs. 3.8%; P < 0.001). Multivariate logistic regression analysis showed that a pre-CCRT PIV > 68 was independently associated with significantly higher rates of RIT.

Conclusion: Higher pretreatment levels of the novel PIV/Hb index predict increased RIT rates following definitive CCRT for LA-NPCs.

Background: As cancer survivorship continues to improve, the perioperative morbidity and mortality following surgical treatment of metastatic bone disease become an increasingly important consideration. The objective of this study is to identify risk factors for early postoperative complications and mortality following extremity prophylactic fixation and pathologic fracture stabilization.

Methods: A single-centre retrospective review of 185 patients (226 total surgeries) who underwent prophylactic fixation or pathologic fracture stabilization for extremity metastatic bone disease between 2005 and 2020 was performed. Skull, spine, pelvic, and revision surgeries along with diagnosis of primary bone neoplasm were excluded. Univariate, multivariate, and subgroup analyses were performed to identify predictors and independent risk factors for 30-day postoperative morbidity and mortality.

Results: Primary cancers included lung (n = 41), breast (n = 36), multiple myeloma (n = 35), prostate (n = 16), lymphoma (n = 11), renal cell carcinoma (n = 10), and other (n = 36). The 30-day postoperative complication and mortality rates were 32.30% (n = 73) and 17.26% (n = 39), respectively. The most common complications were pulmonary-related, cardiac events, surgical site infection, sepsis, and thromboembolism. Pathologic fracture, presence of extra-skeletal metastases, longer surgical duration, and blood transfusion requirements were associated with 30-day postoperative complications overall. A past medical history for cardiac disease was also associated with systemic but not local surgical complications. Pathologic fracture, presence of extra-skeletal metastases, lung cancer, blood transfusion requirements, and increasing pack-year smoking history were predictors for 30-day mortality. In the multivariate analysis, pathologic fracture (p=0.016) and presence of extra-skeletal metastases (p=0.029) were independent predictors of complications. For mortality, pathologic fracture (p=0.014), presence of extra-skeletal metastases (p=0.0085), and increased blood transfusion requirements (p=0.048) were independent risk factors.

Conclusions: The findings of this study provide additional guidance for perioperative risk assessment and patient counselling. Additionally, improving clinical assessment tools to identify and quantify patients at risk of pathologic fractures becomes increasingly important given the significant morbidity and mortality associated with pathologic fracture treatment.

Introduction: Thyroid cancer is the most common cancer in women in Ecuador.

Objective: The aim of this study was to determine the demographics and clinical and treatment variables of patients with papillary or follicular thyroid cancer, referred to as differentiated thyroid cancer (DTC), treated at a third-level hospital in Quito, Ecuador.

Methods: We reviewed retrospectively the medical records of patients with DTC, who underwent surgical treatment, from 1990 to 2019. Data included demographics, pathological information, clinical stage, type of surgery, and radioactive iodine (RAI) adjuvant therapy. Patients were monitored for up to 29 years (median follow-up time 6.9 years).

Results: The corrected overall 5-, 10-, 20-, and 30-year survival rates (Kaplan-Meier) were 93%, 85%, 70%, and 63%, respectively. On univariate analysis, age, histological type, tumor grade, histological variants, capsular invasion, vascular invasion, tumor size, clinical stage, distant metastases at diagnosis, surgical margins, extrathyroidal invasion, radioactive iodine adjuvant treatment, and locoregional recurrence were found to be significant prognostic factors. In a multivariate analysis, the following independent variables: age over 55 years, extrathyroidal spread, metastasis at diagnosis, and stage II to IV raised the risk of death (hazard risk) (HR).

Conclusions: Age over 55 years, extrathyroidal spread, metastasis at diagnosis, and advanced clinical stage were found to have a harmful prognosis and an increased risk of death in a series of Ecuadorian patients surgically treated for a DTC.

Introduction: Oral squamous cell carcinoma (OSCC) is the most prevalent type of head and neck cancer and is associated with high mortality, particularly in Southeast Asian countries. Areca nut usage, smoking, and alcohol consumption are the most common risk factors for OSCC. Areca nut chewing is highly prevalent in Pakistan and has been attributed to an increase in OSCC cases. This study aimed to determine the association between areca nut usage and various clinicopathological features of OSCC and further evaluate the association of clinicopathological parameters of OSCC with tumor recurrence.

Materials and methods: The study was conducted using the data of 228 patients with OSCC resected at Liaquat National Hospital, Karachi, Pakistan, over 5 years between 2018 and 2022. Clinicopathological data were collected from hospital archives, and associations between various risk factors and clinicopathological parameters were determined.

Results: Males were more commonly affected (77.2%), and the most common age group was <50 years (54.4%). Areca nut usage was reported in 59.6% of cases, and the buccal mucosa was the most common site (62.7%). Areca nut usage was significantly associated with male gender, greater tumor size, greater depth of invasion (DOI), higher tumor stage, nodal stage, presence of perineural invasion (PNI), and recurrence. In addition, multivariate analysis revealed that OSCC recurrence was significantly associated with older age, larger tumor size and DOI, nodal metastasis, and areca nut usage.

Conclusion: Areca nut-related OSCCs were associated with poor prognosis and recurrence in our study population. Furthermore, OSCC recurrence was associated with various clinicopathological parameters, such as larger tumor size, a higher DOI, and nodal metastasis.

Aim: This study aimed to assess the impact of routine histological examination of stapled colorectal anastomotic doughnuts in patients undergoing rectal cancer surgery (RCS). Justification of biopsy examination could form part of the strategies of NHS net zero practice with effort to reduce wastage and carbon footprint.

Method: A data analysis of all patients undergoing RCS during 2019-2021 at our institute was performed. We also analysed the cost of preparing and reviewing histology slides.

Results: 52 patients underwent anterior resection during the aforementioned period. Doughnuts were sent in 37 (71%) patients. 23 (62%) patients were male, and 14 (38%) were female. The median age at diagnosis was 68 (range 54-84) years. All resected specimens were adenocarcinomas. Of the 37 patients, 18 (49%) underwent low anterior resection and 19 (51%) underwent high anterior resection. Proximal doughnuts were sent in 26 (70%) patients, whereas distal doughnuts were sent in all cases. Mean distal microscopic resection margin from tumour was 22 mm (range 6-45 mm). Each doughnut required 3 slides, each costing £50 and requiring 82 minutes to fix and read. This incurred a cost of £13,650 and required 19,656 hours of preparation time. All of the doughnuts as well as resection margins were negative for malignancy.

Conclusion: Routine histopathological examination of doughnuts is time and cost-intensive however provides little or no clinical value (particularly analysis of the proximal doughnut). Distal doughnuts should only be sent for histological examination in exceptional circumstances.
