Chest wall resection and reconstruction for primary chest wall sarcomas: Analysis of survival, predictors of outcome, and long-term functional status

ObjectivesWe aimed to analyze survival, predictors of outcome, and the long-term functional status of patients with a diagnosis of primary chest wall sarcoma who undergo chest wall resection and reconstruction. MethodsWe analyzed a prospectively maintained database, including all patients operated on between 2008 and 2021. The primary outcome measures were overall and disease-free survival and analyses were employed to determine the risk factors for poor survival and recurrence. ResultsOne hundred thirty-nine patients were included, 55% were men. The majority (96%) had an R0 resection and 75.1% had no postoperative complications up to 30 days postprocedure; median length of hospital stay was 7 days (range, 6-10 days). Median overall and disease-free survival was 58.8 and 53.6 months, respectively. For those alive, at long-term follow-up, 80% had a Medical Research Council dyspnea score of 0 and Karnofsky index >80%. Survival and mortality rates were better in chondrosarcomas compared with nonchondromatous sarcomas (P < .05). Previous history of radiotherapy, previous history of cancer, the type of sarcoma (Ewing's or soft tissue), the need for adjuvant treatment and tumor grade were significant predictors of mortality and recurrence on univariate testing. Extended resection, a higher number of ribs removed, and the incidence of postoperative complications were significantly associated with a worse postoperative Medical Research Council dyspnea score. ConclusionsCareful patient selection and multidisciplinary decision making is crucial. This leads to clear resection margins, good overall, and disease-free survival and good functional outcomes.

Cutaneous Squamous Cell Carcinoma of the Head and Neck: Pathological Features and What They Mean for Prognosis and Treatment.

Cutaneous squamous cell carcinoma (cSCC) is one of the most common cancers worldwide, with an incidence that has increased over the past 30 years. Although usually curable with excision, cSCC can become widely metastatic and aggressive with poor outcomes. Whereas the clinical and radiographic extent of any cancer will always guide selection of treatment modality, pathological features of cSCC also play an important role in determining prognosis and, subsequently, the need for further therapy. Therefore, reviewing and summarizing the current literature regarding pathological prognostic indicators of cSCC is essential to improving clinical outcomes. The present literature review yielded depth of invasion, surgical margins, perineural invasion, extranodal extension, lymphovascular invasion, tumor grade, tumor subtype, premalignant lesions, and molecular markers as key prognostic indicators, all with varying recommendations for adjuvant therapy. Notably, some of these factors have not been incorporated into either the American Joint Committee on Cancer staging system (8th edition) or National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology for cSCC. This review highlights a need for further research into these prognostic indicators and their role in determining the need for adjuvant treatment in head and neck cSCC.

The impact of arachnoid structures on skull-base meningioma surgical management: a radiological analysis and narrative review.

The presence of intact arachnoid membranes between skull base meningiomas and critical neurovascular structures is crucial for predicting surgical outcomes, understanding tumor development and growth, and planning the feasibility of tumor resection or the need for adjuvant treatments. While neurosurgeons often utilize the subarachnoid cisterns to enhance access to these tumors and facilitate their removal, a comprehensive review aimed at health professionals involved in the diagnosis and treatment of this complex pathology, including radiologists, neurologists, oncologists, ophthalmologists, and neurosurgeons is still lacking. This study aims to summarize the interaction between skull base meningiomas, subarachnoid cisterns, and arachnoid membranes, emphasizing their significance in both the diagnosis and treatment of this pathology. By conducting a thorough radiological assessment of skull base meningiomas, correlating these findings with intraoperative observations, and reviewing relevant literature, we summarize the critical relationship between skull base meningiomas and the surrounding subarachnoid spaces. We concisely describe how arachnoid structures influence tumor growth and interaction with neurovascular elements. We advocate for the inclusion of tumor-arachnoid relationships in the medical literature concerning the treatment of these tumors. A better understanding and description of the interaction between tumors and neurovascular structures will aid in planning and attempting safer treatments, minimizing surgical risks, predicting potential tumor progression, and the need for adjuvant treatments.

A Bosniak III Cyst Unmasking Tubulocystic Renal Cell Carcinoma in an Adolescent: Management with Selective Arterial Clamping and Robotic Enucleation

The Bosniak classification of renal cysts aims to provide a probabilistic risk assessment indicating the likelihood of malignancy from imaging findings. Originally designed to classify adult renal cysts based on computed tomography findings, the Bosniak classification has been extended to pediatric patients, with some adjustments made with the aim of accommodating magnetic resonance imaging (MRI) and ultrasonography (US). Bosniak IV lesions are rare in adolescents, indicating localized renal cell carcinoma and requiring surgical intervention. In contrast, Bosniak III lesions can be treated conservatively, although there is a lack of specific guidelines on their management. We present a case of a 14-year-old boy with a Bosniak III lesion, which was incidentally detected during the US evaluation of a left varicocele. After a 12-month follow-up, MRI revealed progression to a Bosniak IV cyst. Robot-assisted tumor enucleation was performed with selective artery clamping when the patient was 15. Histopathology showed tubulocystic renal cell carcinoma without adverse features. Immunocytochemistry supported a favorable prognosis of this rare tumor (&lt;1% of renal tumor), thus obviating the need for adjuvant treatment. At the 18-month follow-up, no recurrence or distant metastasis were observed. This case highlights the importance of an aggressive treatment in persistent Bosniak III and Bosniak IV renal cysts in children and adolescents and the necessity to offer a nephron-sparing surgery.

Effect of low uterine segment involvement on prognosis of early stage endometrial cancer.

Our aim is to investigate the effect of uterine lower segment involvement on prognosis of early-stage endometrial cancer cases diagnosed and treated in our clinic. The file records of 316 cases reviewed retrospectively.Only stage I (a and b, n=209) cases were investigated, because they were more homogeneous group. The lymphovascular invasion rate was found to be higher in patients with stage Ia and uterine lower segment involvement (p < 0.001). Adjuvant treatment requirement was higher in patients with stage Ia and uterine lower segment involvement (p < 0.001). Among stage Ia cases, the recurrence rate between 1 and 3 years was found to be higher in cases with uterine lower segment involvement (p = 0.001). Among the stage Ib cases, lymphovascular invasion was found to be higher in cases with uterine lower segment involvement (p < 0.001). The recurrence rate between 1 and 3 years was found to be higher in stage Ib compared to Ia (p = 0.01). Uterine lower segment involvement was found to be associated with high lymphovascular invasion rate in all stage I cases (p < 0.001). It was determined that the need for adjuvant treatment was higher in cases with uterine lower segment involvement (p < 0.001). It was determined that the probability of recurrence between 1 and 3 years was higher in cases with uterine lower segment involvement (p = 0.007). Uterine lower segment involvement is associated with increased lymphovascular invasion even in the early stages. It is an important risk factor for systemic spread such as lymphovascular invasion, myometrial invasion, and lymph node involvement.

The Role of Sentinel Lymph Node Biopsy in the Management of Merkel Cell Carcinoma: A Systematic Review and Meta-analysis.

Merkel cell carcinoma (MCC) is a rare cutaneous malignancy with high metastatic potential. Sentinel lymph node biopsy (SLNB) is used to assess locoregional spread, facilitate staging, and inform prognosis. Positive nodal status is associated with higher recurrence rates and reduced overall survival. A systematic search was conducted. Eligible articles included patients diagnosed with MCC, who would be candidates for or who had SLNB. The Covidence tool was used for screening and data extraction, including additional treatments, disease-free survival, overall survival, and recurrence. Methodological quality was assessed using the Newcastle-Ottowa Scale criteria. SLNB was associated with increased likelihood of completion lymphadenectomy (223 versus 41), regional radiotherapy (2167 versus 808), and systemic chemotherapy (138 versus 31). Overall survival for patients undergoing SLNB was 81% at 2 years, 75% at 3 years, and 72% at 5 years (odds ratio: 0.79). Hazard ratio for positive SLNB versus negative was 3.36 (P < 0.001). Five-year disease recurrence was 23.3% in patients undergoing SLNB. Lymph node metastases are associated with reduced overall survival and increased recurrence of MCC. Determining nodal status early can inform prognosis, facilitate staging, and determine need for adjuvant treatment. Adjuvant treatments are associated with reduced mortality and improved overall survival; SLNB is an important influencer of their use. Early prophylactic intervention should be considered in MCC in both positive and negative nodal status to improve overall outcomes. Widespread use of SLNB will allow more accurate assessment of the role of nodal status on adjuvant treatment and long-term outcomes.

NButGT Reinforces the Beneficial Effects of Epinephrine on Cardiac Mitochondrial Respiration, Lactatemia and Cardiac Output in Experimental Anaphylactic Shock.

Anaphylactic shock (AS) is the most severe form of acute systemic hypersensitivity reaction. Although epinephrine can restore patients' hemodynamics, it might also be harmful, supporting the need for adjuvant treatment. We therefore investigated whether NButGT, enhancing O-GlcNAcylation and showing beneficial effects in acute heart failure might improve AS therapy. Ovalbumin-sensitized rats were randomly allocated to six groups: control (CON), shock (AS), shock treated with NButGT alone before (AS+pre-Nbut) or after (AS+post-Nbut) AS onset, shock treated with epinephrine alone (AS+EPI) and shock group treated with combination of epinephrine and NButGT (AS+EPI+preNBut). Induction of shock was performed with an intravenous (IV) ovalbumin. Cardiac protein and cycling enzymes O-GlcNAcylation levels, mean arterial pressure (MAP), heart rate, cardiac output (CO), left ventricle shortening fraction (LVSF), mitochondrial respiration, and lactatemia were evaluated using Western blotting experiments, invasive arterial monitoring, echocardiography, mitochondrial oximetry and arterial blood samples. AS decreased MAP (-77%, p < 0.001), CO (-90%, p < 0.001) and LVSF (-30%, p < 0.05). Epinephrine improved these parameters and, in particular, rats did not die in 15 min. But, cardiac mitochondrial respiration remained impaired (complexes I + II -29%, p < 0.05 and II -40%, p < 0.001) with hyperlactatemia. NButGT pretreatment (AS+pre-Nbut) efficiently increased cardiac O-GlcNAcylation level as compared to the AS+post-Nbut group. Compared to epinephrine alone, the adjunction of NButGT significantly improved CO, LVSF and mitochondrial respiration. MAP was not significantly increased but lactatemia decreased more markedly. Pretreatment with NButGT increases O-GlcNAcylation of cardiac proteins and has an additive effect on epinephrine, improving cardiac output and mitochondrial respiration and decreasing blood lactate levels. This new therapy might be useful when the risk of AS cannot be avoided.

Outcome of Adjuvant Radiotherapy and Adjuvant Chemoradiation for Oral Cancers with Close Margins of Resection.

Oral cancers comprise 50% of all head and neck malignancies in India which can be attributed to tobacco chewing. Advanced oral cancers are managed with surgery followed by adjuvant radiotherapy or adjuvant chemoradiation. There is paucity of studies regarding need for adjuvant treatment in oral cancers with close margins i.e. ≤ 0.5cm after formalin fixation. This study aims at documenting the oncological outcome with regards to loco-regional control, disease-free survival, overall survival and complications of adjuvant radiotherapy and adjuvant chemoradiation in operated oral cancer patients having close margins of resection. In this Retrospective cohort study, 163 patients with stage T1-T4 oral cancers operated between 2015 and 2019 who have fulfilled the inclusion and exclusion criteria, received adjuvant treatment and could be followed up for at least one year were included. At the end of 45months, the overall survival was 74.7% and disease specific survival was 82.7%. Among the 7 patients who defaulted radiotherapy, 4 patients succumbed to the disease. Complications were bone marrow depression (2 patients), dysphagia (17) and Trismus (1). Adjuvant radiotherapy should be given in oral cancer patients with close margins of resection since it improves the oncological outcome and disease specific survival and the benefit often outweighs the risk.

Squamous cell carcinoma in situ of the vulva

Currently, squamous vulvar cancer is rare, which is why there is limited experience among health personnel in recognizing and managing this type of tumor location. The purpose of this case is to present the case of an 87-year-old woman with an ulcerative lesion on the vulva who underwent left vulvectomy with a report of squamous cell carcinoma in situ pathology, with favorable post-surgical evolution and without the need for adjuvant treatment when the inguinal lymph node was negative for metastasis.

Neo-adjuvant chemotherapy and transoral robotic surgery in locoregionally advanced oropharyngeal cancer

PurposeTo analyze the oncological outcomes and patterns of recurrence of patients with locoregionally advanced oropharyngeal squamous cell carcinoma (OPSCC) who underwent neo-adjuvant chemotherapy (NCT) with subsequent transoral robotic surgery (TORS). MethodsA single-center retrospective cohort study was performed, including 198 patients (mean age: 58.6, SD: 9.2). The primary outcome was disease-free survival (DFS). ResultsThe median follow-up time was 26.5 months (IQR: 16.0–52.0). Estimated DFS rates (95 % CI) at 1 and 3 years were 86.6 % (81.9–91.7), and 81.4 % (75.7–87.6), respectively. Estimated DSS rates (95 % CI) at 1 and 3 years were 96.7 % (94.1–99.3), and 92.6 % (88.4–97.0), respectively. Estimated OS rates (95 % CI) at 1 and 3 years were 96.2 % (93.4–99.0), and 88.7 % (83.4–94.2), respectively. A total of 31 (15.6 %) patients showed a disease relapse after a median time of 8 months (IQR: 4.0–12.0), but only 12 (6 %) patients died of the disease during the study period. ConclusionsThis study demonstrates that NCT and TORS can obtain excellent tumor control and survival in locoregionally advanced OPSCC. NCT might reduce the need for adjuvant treatments, and randomized clinical trials should be conducted to better define this aspect.

Stereotactic biopsy for brain lesions: Doing more with less.

Stereotactic biopsy (STB) is a potential diagnostic tool considering its minimal invasiveness, high diagnostic yield, and minimal associated complications. Over the years, various frame-based instrument systems and frameless stereotactic biopsy systems have emerged to be employed in clinical use. With this study, we intend to get more by doing less in the form of STB for the patients of doubtful intracranial lesions treated over the past 5 years. We also want to highlight the technique of performing the procedure under scalp block, which can be used as a versatile tool in many clinical scenarios. Stereotactic biopsies may be planned even in rural district-level health facilities. One-time investment to procure instruments and avail existing imaging can lead to establishing definitive diagnoses in many doubtful cases. This will result in lesser cost and early establishment of treatment. Independent risk factors determining the outcome, such as deep-seated lesions, associated edema, and intraoperative hypertension, were studied. Establishing the diagnosis helped in prognosticating the disease, explaining the natural progression of symptoms, and starting adjuvant therapy. This tissue biopsy would also help secure samples for research and molecular analysis. Twenty patients underwent STBs at our institution between January 2018 and December 2022. We retrospectively analyzed patient characteristics, tumor pathology, surgical procedures, and outcomes, including the diagnostic value and surgery-related complications. These patients were followed up, and their progression-free and overall survival were analyzed. The need for adjuvant treatment was noted and analyzed. All procedures were performed using Cosman Roberts Wells® stereotactic frame. Pre-procedure magnetic resonance scans were performed at the time of admission. Contrast-enhanced computerized tomography (CT) scan after frame application was performed to identify targets and calculate the coordinates. A post-procedure CT scan was done to confirm the accessibility of the targeted lesion. The most common location of the tumor was a deep-seated thalamic lesion. A definitive diagnosis was established in 19 patients (95%) at the first STB. The diagnoses were glioma in 55% of cases, primary central nervous system lymphoma, tuberculosis, and demyelinating disorders in 10% of each, and a metastatic brain tumor in 1 (5%). The post-operative complications were all transient except in one patient with deterioration of motor weakness. The follow-up was noted, and modes of adjuvant treatment needed in these patients were recorded. Stereotactic biopsy is a useful and effective method for achieving a definitive diagnosis and aiding in treating multifocal or small deep-seated lesions in or around eloquent regions.

Technical nuances for the resection of cervical dumbbell schwannomas.

The majority of spinal nerve sheath tumors are within the intradural/extramedullary compartment. A subset of these tumors develop extraforaminal components that gradually expand into potential spaces. Herein, the authors provide a 2D video demonstrating the technical nuances concerning resection of cervical dumbbell schwannomas with extraspinal extension. Although nerve sheath tumors with large extraforaminal extension are often associated with complications and pose unique challenges to surgeons, circumferential exposure with intradural exploration allows for gross-total resection and nerve root preservation, without need for adjuvant treatments. The use of intraoperative ultrasound, neurophysiological monitoring, Doppler imaging, and meticulous surgical techniques aided to circumvent complications.

Adjuvant therapeutic strategy decision support for an elderly population with localized breast cancer: A monocentric cohort retrospective study.

Guidelines for the management of elderly patients with early breast cancer are scarce. Additional adjuvant systemic treatment to surgery for early breast cancer in elderly populations is challenged by increasing comorbidities with age. In non-metastatic settings, treatment decisions are often made under considerable uncertainty; this commonly leads to undertreatment and, consequently, poorer outcomes. This study aimed to develop a decision support tool that can help to identify candidate adjuvant post-surgery treatment schemes for elderly breast cancer patients based on tumor and patient characteristics. Our approach was to generate predictions of patient outcomes for different courses of action; these predictions can, in turn, be used to inform clinical decisions for new patients. We used a cohort of elderly patients (≥ 70 years) who underwent surgery with curative intent for early breast cancer to train the models. We tested seven classification algorithms using 5-fold cross-validation, with 80% of the data being randomly selected for training and the remaining 20% for testing. We assessed model performance using accuracy, precision, recall, F1-score, and AUC score. We used an autoencoder to perform dimensionality reduction prior to classification. We observed consistently better performance using logistic regression and linear discriminant analysis models when compared to the other models we tested. Classification performance generally improved when an autoencoder was used, except for when we predicted the need for adjuvant treatment. We obtained overall best results using a logistic regression model without autoencoding to predict the need for adjuvant treatment (F1-score = 0.869).

LABIAL SQUAMOUS CELL CARCINOMA IN A YOUNG PATIENT

A 27-year-old, leukoderma male patient, sought out dental care complaining of burning and a lesion on the lower lip. The patient had no risk factors and presented a history of trauma in the region. Intraoral examination identified a nodular lesion in the lower lip, firm, with ulcered surface, measuring about 1.0 cm, with an evolution of approximately 2 months. The diagnostic hypothesis was mucocele. An excisional biopsy was performed, and the result of the histopathological analysis was moderately differentiated squamous cell carcinoma (SCC). The patient underwent surgical treatment with no need for adjuvant treatment. SCC is more prevalent in males, with a peak incidence between 50 and 70 years of age. The relevance of the case is related to the patient´s early age and the importance of the histopathological analysis to confirm the diagnosis to establish adequate treatment.

Molecular classification of endometrial carcinoma: Analysis of a multicentre Portuguese cohort.

e17615 Background: Management of endometrial carcinoma (EC) relies on prognostic risk group classification to help to determine the individual risk of recurrence and the need for adjuvant treatment after surgery. A molecular classification with four distinct prognostic EC subtypes based on genomic abnormalities - DNA polymerase epsilon ( POLE) mutated ( POLEmut), mismatch repair deficient (MMRd), p53 abnormal (p53abn) and no specific molecular profile (NSMP) - has emerged, that raises the possibility of a more precise tailoring of adjuvant therapy. This study aimed to describe the clinicopathological and molecular characteristics of an EC Portuguese cohort, assess its potential impact in patient management and evaluate its prognostic value. Methods: Multicentre, retrospective cohort study of 230 patients with EC diagnosed between 2019 and 2022. Sample processing, clinicopathological, treatment and follow-up data was collected. Molecular classification was obtained by p53 and mismatch repair proteins immunohistochemistry, and POLE next-generation sequencing. Results: Overall, 230 patients from two institutions were included. Median age at diagnosis was 68 years. The most frequent histology was endometrioid (n=163; 70.9%) and most were low-grade (n=129, 56.1%).At diagnosis, disease was confined to the uterus in the majority of patients (FIGO stage I/II, n=153, 66.5%). Most had surgery upfront (n=196, 85.2%) and, of those, 120 (52.2%) received adjuvant treatment. 26 (11.3%) had metastatic disease. Median follow-up time was 15.4 months. Regarding molecular subgroups, the majority were classified as NSMP (n=87, 37.8%), followed by p53abn (n=73, 31.7%), MMRd (n=56, 24.3%), and POLEmut (n=14, 6.1%); 11 (4.8%) were multiple-classifier. Integration of these results led to a change in adjuvant treatment in 3 patients. Median disease-specific survival (DSS) was 108 months. Factors that significantly influenced survival included age (p=0.030), histological type (p&lt;0.001), grade (p&lt;0.001) and FIGO stage (p=0.006). Overall, 35 (15.2%) patients developed recurrences. Median recurrence-free survival (RFS) was 46.7 months. Kaplan-Meier survival analysis showed that molecular alterations were significantly associated both with DSS and RFS (p=0.0092 and p=0.0139, respectively). Tumours with p53abn had the worst prognosis, and patients with POLEmut tumours experienced an excellent prognosis. Comparative measures (BIC, C-index, log-likelihood) showed that considering the molecular classification in establishing risk groups for adjuvant treatment had prognostic significance. Conclusions: The molecular classification has prognostic value and should be considered in adjuvant treatment decisions. It allows for a more personalised approach, helps to reduce under and overtreatment, and therefore reduce patient morbidity associated with treatment toxicities, and healthcare related costs.

Image-Guided Intraoperative Assessment of Surgical Margins in Oral Cavity Squamous Cell Cancer: A Diagnostic Test Accuracy Review.

(1) Background: The assessment of resection margins during surgery of oral cavity squamous cell cancer (OCSCC) dramatically impacts the prognosis of the patient as well as the need for adjuvant treatment in the future. Currently there is an unmet need to improve OCSCC surgical margins which appear to be involved in around 45% cases. Intraoperative imaging techniques, magnetic resonance imaging (MRI) and intraoral ultrasound (ioUS), have emerged as promising tools in guiding surgical resection, although the number of studies available on this subject is still low. The aim of this diagnostic test accuracy (DTA) review is to investigate the accuracy of intraoperative imaging in the assessment of OCSCC margins. (2) Methods: By using the Cochrane-supported platform Review Manager version 5.4, a systematic search was performed on the online databases MEDLINE-EMBASE-CENTRAL using the keywords "oral cavity cancer, squamous cell carcinoma, tongue cancer, surgical margins, magnetic resonance imaging, intraoperative, intra-oral ultrasound". (3) Results: Ten papers were identified for full-text analysis. The negative predictive value (cutoff < 5 mm) for ioUS ranged from 0.55 to 0.91, that of MRI ranged from 0.5 to 0.91; accuracy analysis performed on four selected studies showed a sensitivity ranging from 0.07 to 0.75 and specificity ranging from 0.81 to 1. Image guidance allowed for a mean improvement in free margin resection of 35%. (4) Conclusions: IoUS shows comparable accuracy to that of ex vivo MRI for the assessment of close and involved surgical margins, and should be preferred as the more affordable and reproducible technique. Both techniques showed higher diagnostic yield if applied to early OCSCC (T1-T2 stages), and when histology is favorable.

SUCCOR Nodes: May Sentinel Node Biopsy Determine the Need for Adjuvant Treatment?

BackgroundThe SUCCOR cohort was developed to analyse the overall and disease-free survival at 5 years in women with FIGO 2009 stage IB1 cervical cancer. The aim of this study was to compare the use of adjuvant therapy in these women, depending on the method used to diagnose lymphatic node metastasis.Patients and MethodsWe used data from the SUCCOR cohort, which collected information from 1049 women with FIGO 2009 stage IB1 cervical cancer who were operated on between January 2013 and December 2014 in Europe. We calculated the adjusted proportion of women who received adjuvant therapy depending on the lymph node diagnosis method and compared disease free and overall survival using Cox proportional-hazards regression models. Inverse probability weighting was used to adjust for baseline potential confounders.ResultsThe adjusted proportion of women who received adjuvant therapy was 33.8% in the sentinel node biopsy + lymphadenectomy (SNB+LA) group and 44.7% in the LA group (p = 0.02), although the proportion of positive nodal status was similar (p = 0.30). That difference was greater in women with negative nodal status and positive Sedlis criteria (difference 31.2%, p = 0.01). Here, those who underwent a SNB+LA had an increased risk of relapse [hazard ratio (HR) 2.49, 95% confidence interval (CI) 0.98–6.33, p = 0.056] and risk of death (HR 3.49, 95% CI 1.04–11.7, p = 0.042) compared with those who underwent LA.ConclusionsWomen in this study were less likely to receive adjuvant therapy if their nodal invasion was determined using SNB+LA compared with LA. These results suggest a lack of therapeutic measures available when a negative result is obtained by SNB+LA, which may have an impact on the risk of recurrence and survival.

Malignant salivary gland tumours: treatment outcomes from a tertiary referral centre in the UK

Salivary gland malignant tumours are a complex and highly variable pathological group. Their diagnosis can be challenging, and management is guided by multidisciplinary teams. This project aimed to establish clinicopathological and sociodemographic features that significantly impacted overall disease-free or progression-free survival in patients diagnosed with malignant salivary gland disease between 2010 and 2019 in a tertiary referral centre. In total, 86 patients were included for analysis, with a female:male gender ratio of 1.3:1. Mean age at diagnosis was 57.7 years. Mucoepidermoid carcinomas constituted almost 25% (n = 20) of all cases, with adenoid cystic carcinomas (20%, n = 17) and acinic cell carcinomas (17.5%, n = 15) being the next most frequently diagnosed. The parotid gland was the most frequently affected site (80.2%, n = 69). Perineural and lymphovascular invasion, and a maximum tumour dimension of ≥4 cm were highly associated with the decision to provide a neck dissection as part of treatment. Involved margins, extracapsular spread, and lymphovascular and perineural invasion were associated with the need for adjuvant treatment. However, no factors remained statistically significant on multivariate analysis. This retrospective service evaluation demonstrates the difficulty of predicting treatment outcomes for patients diagnosed with malignant salivary gland disease.
