Background/Objectives: Pelvic exenteration (PE) might be a curative option for patients with advanced pelvic malignancies. Due to its significant morbidity and mortality rates, PE necessitates meticulous patient selection, and a comprehensive understanding of disease spread. This study outlines the experience at a single tertiary referral center and investigates prognostic factors influencing survival post-PE, thereby guiding clinical decision-making processes. Methods: Patients undergoing PE for advanced pelvic gynecological malignancies between 01/2016 and 12/2023 were retrospectively analyzed using a prospectively managed database. Eligibility for PE was determined through individualized tumor board evaluations based on CT/MRI imaging, excluding patients with distant metastases. Baseline demographic and clinical characteristics, operative details, complication rates, and histopathological findings were assessed using univariate and multivariate regression analyses. Disease-free (DFS) and overall survival (OS) were assessed by Kaplan-Meier analysis. Poor outcome prognostic factors were identified, outlining an optimal candidate profile for PE. Results: A total of 70 patients were included. The median age was 54.5 years. Forty-three patients (61.4%) presented with recurrent disease and the majority were diagnosed with cervical cancer (n = 48, 68.6%). Total PE was performed in 40 patients (57.1%), with complete tumor resection achieved in 68.6% of patients (n = 48). Sixteen patients (22.8%) experienced grade IV/V complications. Median DFS and OS were 8.2 and 16.4 months, respectively. Multivariate analysis identified R1 resection status and para-aortic lymph node involvement as independent negative prognostic factors. Conclusions: PE is a viable option for selected patients with advanced primary and recurrent pelvic gynecological malignancies. When complete tumor resection is feasible, patients may derive benefit from PE, although the risk of severe perioperative complications must be carefully evaluated. Full article

The strategy of active surveillance for papillary thyroid microcarcinoma (PTMC) is becoming increasingly popular within the global medical community. A key criterion for selecting this strategy is the absence of any signs of lymphogenic or distant metastases. The present study assessed the diagnostic accuracy of molecular genetic markers for predicting the metastatic potential of patients with PTMC. We evaluated the expression levels of 33 molecular genetic markers in cytology samples from 92 patients with PTMC and confirmed histological diagnosis. Among these patients, 32 had metastases to regional cervical lymph nodes. Our findings revealed the upregulated expression of the HMGA2, TIMP1, and FN1 genes, as well as microRNA-146b, in patients with metastatic PTMC. Conversely, we found the downregulated expression of miRNA-7 and -148b in metastatic tumors. In metastatic tumors, significant reductions were observed in DIO1 activity (11-fold), TFF3 gene expression (8-fold), TPO expression (4-fold), and SLC26A7 expression (2.6-fold). All the markers exhibited high sensitivity (84.5–90.6%) in detecting metastatic PTMC, although the specificity proved to be low. The use of molecular markers to predict lymphogenic metastatic spread in patients with PTMC could enhance existing risk grading systems. Such assessments can already be applicable at the preoperative stage. Full article

Objective: This study aims to explore the benefit of adjuvant chemoradiotherapy compared with radiotherapy alone following a radical hysterectomy with pelvic lymphadenectomy. The study focuses on patients with clinically early-stage squamous cervical cancer who have a single high-risk factor postoperatively. Methods: This retrospective study included women diagnosed between 2001 and 2018, with: (1) clinical tumour (cT) stage 1A2–2A2, (2) cervical squamous carcinoma, (3) treated with radical hysterectomy and pelvic lymphadenectomy (4) followed by adjuvant (chemo)radiotherapy, and with (5) one high-risk factor (i.e., positive resection margins, parametrial involvement, or pelvic lymph node metastases). Recurrence-free and overall survival were estimated using Kaplan−Meier and Cox proportional hazards analyses. Inverse probability treatment weighting was used to adjust for confounding. Results: Of the 122 patients with squamous cell carcinoma and one high-risk factor, 76 (62%) received adjuvant chemoradiotherapy and 46 (38%) received adjuvant radiotherapy alone. Larger tumour size, tumour grade 3, and pathological parametrial invasion were more common in the radiotherapy group, while patients who received chemoradiotherapy were more likely to have multiple lymph node metastases. The unadjusted and for confounding adjusted 5-year survival rates were comparable between the adjuvant chemoradiotherapy and radiotherapy groups for both recurrence-free survival (85% versus 87%; p = 0.58, and 84% versus 91%; p = 0.49) and overall survival (84% versus 87%; p = 0.51, and 84% versus 91%; p = 0.49). Conclusions: Adding chemotherapy to radiotherapy may not improve survival of patients with early squamous cervical cancer treated with radical hysterectomy and pelvic lymphadenectomy, and with a single postoperative high-risk factor.

Background/Objectives: Papillary thyroid carcinoma (PTC) accounts for the majority of thyroid cancers, with lymph node metastasis, including skip metastasis (SM), playing a crucial role in guiding prognosis and therapeutic planning. SM, characterized by lateral lymph node spread in the absence of central compartment involvement, has been observed in PTC with a wide range of reported frequencies. The identification of risk factors for SM is crucial for preoperative evaluation and surgical planning. This research aims to explore the clinicopathological features and potential risk factors linked to SM in patients with PTC, while also offering valuable insights for preoperative risk evaluation. Methods: A retrospective cohort study was conducted on 81 PTC patients who underwent central and lateral cervical lymph node dissection (LND) in our center. Clinical, demographic, and pathological data, including age, sex, tumor size, location, subtype, extrathyroidal extension, lymphovascular invasion, and the number of lymph node metastases were analyzed. Clinicopathological characteristics were analyzed between SM-positive and SM-negative patient groups using suitable statistical methods. Additionally, a regression analysis was performed to identify the risk factors for SM. Results: Of the 81 patients, 17.3% (n = 14) were diagnosed with skip metastasis (SM). The SM-positive group had a significantly higher age (p = 0.006), smaller tumor size (p < 0.001), and higher rates of extrathyroidal extension (p = 0.006). The proportion of female patients was elevated in the SM-positive group, but this observation did not achieve statistical significance (p = 0.128). Tumors located in the upper pole were more common in the SM-positive group (p = 0.016). Multivariate analysis revealed that female sex, older age, and tumor location in the upper pole were significant risk factors for SM (p = 0.031, p = 0.004, and p = 0.017, respectively), while a lower number of lateral lymph node metastases was significantly associated with SM (p = 0.010). Additionally, an age over 43.5 years predicted SM with a sensitivity of 78.6% and a specificity of 72.7%. Conclusions: Skip metastasis is not uncommon in PTC and may be associated with older age, female sex, upper pole tumor location, and fewer lateral lymph node metastases. Recognizing these factors during preoperative assessment may aid in anticipating atypical lymphatic spread patterns and optimizing surgical strategies. Full article

In this article, we present a case of a 49-year-old woman presenting with a recurrent metastatic neuroendocrine tumor. Background: Insulinomas are neuroendocrine tumors derived from beta cells of the pancreas that secrete insulin. Usually, they are benign tumors; however, metastatic insulinomas are an extremely rare malignant form of these tumors, carrying a significantly worse prognosis. Case Presentation: A 49-year-old woman, a patient in the University Hospital in Wroclaw in the Department of Endocrinology, Diabetes and Isotope Therapy, first presented with abdominal pain in 2009, when ultrasound and further examination led to the diagnosis of a tumor in the pancreas (a solid pseudopapillary tumor of the pancreas—meta NET G2), and the patient underwent distal pancreatectomy with splenectomy. For ten years, she was under observation, and her symptoms, such as abdominal pain, nausea, weight loss, and general weakness, reappeared in 2019. Then, magnetic resonance imaging (MRI) showed a lesion in the liver, and further histopathology revealed neuroendocrine tumor (NET) metastasis to the liver. In 2022, the patient presented with loss of consciousness and convulsion, loss of weight, and hypoglycemia after meals. In April 2022, the daily glycemic profile was recorded and a 72 h fasting test was performed; however, their results excluded insulinoma. Positron emission tomography–computed tomography (PET-CT) with 18F-fluorodeoxyglucose (18F-FDG) and PET with gallium-68-DOTA-(Tyr3)-octreotate (68Ga-DOTA-TATE) showed a metastatic proliferative process in the liver. Persistent hypoglycemia led to another hospitalization in May 2022, and repeated tests allowed for the diagnosis of insulinoma. Treatment with somatostatin analogs and diazoxide was started. A CT scan in November 2022 and a PET scan in January 2023 showed new metastases to the liver, bones, and cervical lymph nodes, and it was decided to intensify the treatment. In May 2023, the patient was qualified for Lutathera treatment for insulinoma at the University Clinical Hospital in Poznań. In June 2023, another disturbing symptom was reported by the patient, a painful lump in the breast. During diagnostics, metastases with high proliferation markers were found in both breasts. Two months later, in August 2023, the patient received another dose of Lutathera. In October 2023, significant progression of liver lesions, metastases to bones of the spine, ribs, and pelvis, and periaortic and pelvic lymphadenopathy were found as well as elevated values of neuron-specific enolase and calcitonin. The patient was also referred to the Palliative Medicine Home Hospice. In consultation with the Lower Silesian Cancer Center, the decision was made to forgo further treatment with PRRT and initiate systemic chemotherapy. Despite the chosen treatment, the patient died on 27/DEC/2023. Conclusions: This case report can serve clinicians, as it presents a case of an extremely rare and insidious tumor, metastatic insulinoma. Full article

Despite advancements in multidisciplinary treatment, esophagectomy remains the primary curative treatment for esophageal cancer. Given that lymph node metastases can spread from the cervical to abdominal regions, three-field lymph node dissection has been established as a standard approach. However, this highly invasive procedure involves multiple anatomical regions—thoracic, abdominal, and cervical—leading to significant surgical burden. To reduce surgical invasiveness, minimally invasive esophagectomy (MIE) has become increasingly common worldwide. With its adoption and advancements in multidisciplinary therapy, discussions have emerged regarding the potential omission of lymph node dissection in selected cases. Since the introduction of robot-assisted minimally invasive esophagectomy (RAMIE) in 2004, this technique has progressively replaced conventional MIE. Robotic systems—equipped with a magnified 3D camera, articulated instruments, and tremor filtering—allow surgeons to perform complex procedures with greater precision than manual techniques. One randomized controlled trial (RCT) has demonstrated fewer postoperative complications with RAMIE compared to open esophagectomy. Additionally, RAMIE has been shown to enable more extensive lymph node dissection around the left recurrent laryngeal nerve than conventional MIE. However, the long-term oncological benefits of RAMIE remain unproven, as no RCTs have definitely confirmed its impact on long-term survival in esophageal cancer patients. Ongoing randomized trials are expected to provide further insights into its prognostic benefits. Full article

Papillary thyroid carcinoma (PTC) frequently involves cervical lymph node (LN) metastases and is a major determinant of prognosis and recurrence. However, cytology alone has limitations. Fine-needle aspiration thyroglobulin (FNA-Tg) has emerged as a promising diagnostic marker, although its cutoff value remains controversial, particularly in patients with thyroglobulin antibodies (TgAbs). We retrospectively analyzed 63 LNs of 60 patients with PTC at a single medical center. Patients underwent FNA-Tg measurements and concurrent cytological evaluation. Diagnostic performance metrics, including sensitivity, specificity, positive and negative predictive value, and overall accuracy, were evaluated; the cutoff value was determined; and the potential influence of factors such as TgAb on FNA-Tg levels was investigated. A cutoff value of 4.23 ng/mL for FNA-Tg achieved 100% sensitivity and 90.2% specificity, with an overall accuracy of 93.6%. TgAb positivity did not significantly affect the diagnostic performance in patients with FNA-Tg. FNA-Tg might be useful for detecting local LN recurrence and providing valuable diagnostic insights, particularly in patients with residual thyroid tissue or positive TgAbs. Full article

Objective: This study aimed to evaluate the reliability and clinical utility of intraoperative sentinel lymph node (SN) metastasis diagnosis using the one-step nucleic acid amplification (OSNA) assay in early-stage cervical cancer by comparing its accuracy with conventional histopathological examination. Methods: A retrospective analysis was conducted on 163 patients who underwent SN biopsy at Kagoshima University Hospital between April 2014 and December 2024. This study included 50 and 113 patients in the OSNA assay and histopathological diagnosis groups, respectively. The OSNA assay quantified cytokeratin 19 (CK19) mRNA levels to determine SN metastasis. The surgical outcomes, SN metastasis detection rates, and non-SN metastasis status were compared between the two diagnostic methods. Results: The SN metastasis detection rate was significantly higher in the OSNA group (12%) than in the pathology group (3%) (p < 0.05). The OSNA assay identified only micrometastases (+) among the positive cases, whereas histopathological diagnosis detected both macrometastases and micrometastases. No non-SN metastases were observed in any of the SN-positive cases, and no significant differences were observed in the recurrence rates between the two groups. Conclusions: The OSNA assay demonstrated a higher SN metastasis detection rate than conventional pathology and demonstrated superior sensitivity in identifying micrometastases. These findings suggest that intraoperative OSNA-based SN assessment in cervical cancer could improve staging accuracy and potentially reduce the need for systematic lymphadenectomy. However, further prospective studies are warranted to confirm these findings and establish clinical guidelines. Full article

Background and Objectives: Thyroid cancer (TC) is a common malignancy that accounts for approximately 1% of all human cancers. Given their anatomical proximity to the thyroid, the parathyroid glands (PTGs) are theoretically at risk of tumor involvement. However, PTG metastases are rare and may be underdiagnosed because of routine PTG preservation during thyroidectomy. This study aimed to identify cases of PTG invasion by TC through a 10-year retrospective review at Chosun University Hospital, along with an analysis of the existing literature. Materials and Methods: A total of 1032 thyroidectomy cases were reviewed, and PTG involvement was detected in 10 cases (0.97%). Clinicopathological characteristics were evaluated, and literature data were analyzed. Results: The affected patients included nine females and one male, with a mean age of 46 years (range: 25–77 years). Histological examination confirmed papillary thyroid carcinoma (PTC) in all cases. Tumor invasion into the perithyroid soft tissues was observed in nine patients, and central cervical lymph node metastases were present in four. All patients exhibited PTG Pattern A (direct invasion). Conclusions: Based on our findings and literature data, PTG involvement by TC has an incidence rate of 0.05–3.9%, predominantly affects women in their sixth to seventh decade of life, and appears to have no impact on prognosis unless accompanied by extensive extrathyroidal invasion. Further studies are necessary to determine whether PTG invasion should be integrated into the TNM staging system and to assess its prognostic and therapeutic implications. Full article

Objectives: In patients undergoing a radical hysterectomy, uterine corpus invasion worsens cervical cancer prognosis. However, the prognostic role of the invasion in locally advanced stages remains elusive. Due to the inadequacy of typical corpus biopsies, corpus invasion is diagnosed using magnetic resonance imaging (MRI). In this study, we investigated the prognostic role of MRI-detected uterine corpus invasion in patients undergoing radiotherapy for cervical cancer. Methods: This retrospective analysis involved 259 patients without extrapelvic metastases, diagnosed with FIGO 2009 stages IB–IVA cervical carcinoma from January 2011 to December 2020. The corpus invasion extent was classified as exocervical-confined (group 1), endocervical (group 2), or uterine corpus invasion (group 3). The rates of overall survival, cancer-specific survival, locoregional recurrence, para-aortic lymph node recurrence, and extrapelvic metastases after pelvic radiotherapy were analyzed. Kaplan–Meier and Cox regression analyses were used to determine recurrence-associated risks. Optimal risk stratification was predicted using a receiver operating characteristic curve with the area under the curve. Results: Groups 1, 2, and 3 included 66.0%, 18.9%, and 15.1% of patients, respectively. The 5-year para-aortic lymph node recurrence rates were 6.3%, 17.2%, and 34.2% (p < 0.001). Uterine corpus invasion was an independent factor for overall survival, cancer-specific survival, locoregional recurrence, extrapelvic metastases, and para-aortic lymph node recurrence. Including uterine corpus invasion in the risk stratification led to higher areas under the curve for overall survival, cancer-specific survival, locoregional recurrence, extrapelvic metastases, and para-aortic lymph node recurrence than using single parameters. Conclusions: In cervical cancer, following pelvic radiotherapy, uterine corpus invasion is a significant prognostic factor. More-aggressive treatments such as extended-field radiotherapy, adjuvant chemotherapy, and immune checkpoint inhibitors as an alternative to standard pelvic radiotherapy with concurrent chemotherapy may be considered in these patients.

Objectives: Oropharyngeal carcinoma is experiencing an increase in incidence and can easily metastasize to the cervical lymph nodes. Therefore, evaluating the tumor boundary and lymph node metastasis before treatment is critical. Both CT and MR may have limitations in describing the specific boundaries of oropharyngeal tumors. To date, no research has applied PET/MR imaging to patients with only oropharyngeal carcinoma and verified its diagnostic value. The aim of our study was to evaluate the diagnostic value of PET/MR in patients with oropharyngeal carcinoma. We prepared PET/MR for comparison with CT/MR for T and N staging, with the aim of exploring the relationship between the imaging parameters and different biological factors. Methods: This was a retrospective, observational study. In total, 13 patients (11 males and 2 females) with oropharyngeal tumors who underwent FDG PET/MR and enhanced CT/MR from July 2021 to December 2022 were retrospectively analyzed. Cohen’s kappa coefficient and the McNemar test were used to compare the consistencies and diagnostic values of FDG PET/MR and enhanced CT/MR imaging in relation to primary tumors and cervical lymph node metastases. Various specific parameters of FDG PET/MR were included in the statistics. Spearman correlation coefficients were used to analyze the relationship between the parameters and the tumor stage, the degree of differentiation, p16 expression, Ki67 expression, and serological tumor markers. Results: The average age of the patients was 61.54 ± 6.62 years old. Preoperative imaging demonstrated good consistency between FDG PET/MR and enhanced CT and MR for the diagnosis of clinical T stage. A total of seven patients underwent surgery directly. Overall, 231 cervical lymph nodes were dissected. Compared to the postoperative histopathological results, PET/MR was significantly more sensitive than enhanced CT/MR imaging (78.57% vs. 50.00%, p < 0.05; 78.57% vs. 64.29%, p < 0.05, respectively). Also, PET/MR showed more accuracy in diagnosing metastatic lymph nodes, but without significance. Combined with PET/MR-specific parameters, the SUV, TLG, and the MTV were found to be higher in the patients with more advanced stages of cancer and lower in those with p16-positive tumors. In addition, they were found to be positively correlated with the level of serum CEA. Conclusions: This is the first study to evaluate the clinical diagnostic value of PET/MR in patients with oropharyngeal carcinoma. We believe that PET/MR has more advantages in describing tumor boundaries. It is more sensitive or even more accurate for the evaluation of metastatic cervical lymph nodes. Full article

Background: Oral tongue squamous cell carcinoma (OTSCC) is a common disease that can cause occult metastasis (OM). Methods: This study aims to investigate the role of the pre-treatment neutrophil-to-lymphocyte ratio (NLR) in predicting the presence of neck OM in early-stage OTSCC. We reprocessed the pre-treatment blood data to calculate the NLR and the PLR on patients treated for OTSCC. We used a logistic regression model and the ROC curve to estimate the probability of metastases in cervical lymph nodes using data from pre-surgery blood tests. Results: During the period under review, 113 patients were treated for OTSCC; however, only 74 met the inclusion criteria and were, therefore, enrolled in the study. Twenty-five patients (35.3%) had lymph node metastases, and 46 (64.7%) did not. Without the NLR influence, the probability of metastasis is less than 50% (β0 = −1.058). A higher NLR value means a higher chance of metastasis. This is shown by the positive value of the NLR level coefficient (β1 = 0.135) and the ROC curve (AUC = 0.83). Conclusions: Our study showed a statistical correlation between high pre-treatment NLR values and neck OM in patients with OTSCC. These results may help to identify which patients are at risk of developing OM and then choose the right treatment. Full article

Background/Objectives: Malignant adrenal tumors comprise both primary adrenal neoplasms and metastatic lesions, with the latter being significantly more common. Squamous cell carcinoma (SCC) of the larynx is a prevalent head and neck cancer that typically spreads to the cervical lymph nodes, with distant metastases being rare. Among such metastases, adrenal gland involvement is particularly uncommon, presenting unique diagnostic and therapeutic challenges. The study aimed to explore the progression, diagnostic process, and therapeutic management of a rare case of SCC of the larynx metastasizing to the adrenal gland, highlighting the role of advanced diagnostic imaging and a multidisciplinary approach in patient care. Methodology: A 66-year-old male with grade 3 SCC of the larynx underwent total laryngectomy, selective cervical lymphadenectomy, and radiotherapy with a dose of 70 Gy. Chemotherapy was discontinued due to hematological complications. Post-treatment monitoring included CT and PET-CT imaging, leading to the detection of a large adrenal mass. Surgical biopsy confirmed metastatic SCC in the adrenal gland, as resection was not feasible due to extensive invasion. Diagnostic imaging and histopathological examination were complemented by biochemical evaluations to assess hormonal activity. Results: The adrenal mass was identified as a metastasis from the laryngeal SCC. Imaging studies provided detailed insights into the lesion’s size, metabolic activity, and non-functional status. Despite comprehensive efforts, the tumor was deemed unresectable, highlighting the aggressive nature of the disease and the limitations of current therapeutic modalities. Conclusions: This rare case emphasizes the importance of early detection, advanced imaging techniques, and interdisciplinary collaboration in managing complex metastatic presentations. It underscores the critical need for further research into systemic treatments, such as immunotherapy, and the development of standardized protocols for rare metastatic patterns. The study contributes to the growing body of literature on the management of uncommon cancer metastases, advocating for individualized patient care and innovation in treatment strategies.

Before performing a thyroidectomy, a range of diagnostic studies is typically conducted to evaluate thyroid function and structure. Ultrasound and elastography are employed to assess the gland’s morphology and to identify nodular goiters that may necessitate fine-needle aspiration cytology (FNAC) or surgical intervention. Cervical adenopathies in patients suspected of thyroid malignancy are also evaluated via ultrasound. FNAC is the most effective diagnostic tool for suspicious thyroid nodules. Computed tomography (CT) is invaluable in assessing the relationship between large goiters and surrounding structures or identifying deep lymph node metastases in thyroid carcinomas. This article discusses the essential preoperative investigations required for thyroidectomy and their impact on surgical decision-making. Full article

Background/Objectives: Cervical cancer primarily disseminates through the lymphatic system, with the metastatic involvement of pelvic and para-aortic lymph nodes significantly impacting prognosis and treatment decisions. Sentinel lymph node (SLN) mapping is critical in guiding surgical management. However, resource-limited settings often lack advanced detection tools like indocyanine green (ICG). This study evaluated the feasibility and effectiveness of SLN biopsy using alternative techniques in a high-risk population with a high prevalence of large tumours. Methods: This prospective, observational study included 42 patients with FIGO 2018 stage IA1–IIA1 cervical cancer treated between November 2019 and April 2024. SLN mapping was performed using methylene blue alone or combined with a technetium-99m radiotracer. Detection rates, sensitivity, and false-negative rates were analysed. Additional endpoints included tracer technique comparisons, SLN localization patterns, and factors influencing detection success. Results: SLNs were identified in 78.6% of cases, with bilateral detection in 57.1%. The combined technique yielded higher detection rates (93.3% overall, 80% bilateral) compared to methylene blue alone (70.4% overall, 40.7% bilateral, p < 0.05). The sensitivity and negative predictive values were 70% and 93.87%, respectively. Larger tumours (>4 cm), deep stromal invasion, and prior conization negatively impacted detection rates. False-negative SLNs were associated with larger tumours and positive lymphovascular space invasion. Conclusions: SLN biopsy is feasible in resource-limited settings, with improved detection rates using combined tracer techniques. However, sensitivity remains suboptimal due to a steep learning curve and challenges in high-risk patients. Until a high detection accuracy is achieved, SLN mapping should complement, rather than replace, pelvic lymphadenectomy in high-risk cases. Full article
