RESUMO

Introduction: Sociodemographic disparities in genitourinary cancer-related mortality have been insufficiently studied, particularly across multiple cancer types. This study aimed to investigate gender, racial, and geographic disparities in mortality rates for the most common genitourinary cancers in the United States. Methods: Mortality data for prostate, bladder, kidney, and testicular cancers were obtained from the Centers for Disease Control and Prevention (CDC) WONDER database between 1999 and 2020. Age-adjusted mortality rates (AAMRs) were analyzed by year, gender, race, urban-rural status, and geographic region using a significance level of p < 0.05. Results: Overall, AAMRs for prostate, bladder, and kidney cancer declined significantly, while testicular cancer-related mortality remained stable. Bladder and kidney cancer AAMRs were 3-4 times higher in males than females. Prostate cancer mortality was highest in black individuals/African Americans and began increasing after 2015. Bladder cancer mortality decreased significantly in White individuals, Black individuals, African Americans, and Asians/Pacific Islanders but remained stable in American Indian/Alaska Natives. Kidney cancer-related mortality was highest in White individuals but declined significantly in other races. Testicular cancer mortality increased significantly in White individuals but remained stable in Black individuals and African Americans. Genitourinary cancer mortality decreased in metropolitan areas but either increased (bladder and testicular cancer) or remained stable (kidney cancer) in non-metropolitan areas. Prostate and kidney cancer mortality was highest in the Midwest, bladder cancer in the South, and testicular cancer in the West. Discussion: Significant sociodemographic disparities exist in the mortality trends of genitourinary cancers in the United States. These findings highlight the need for targeted interventions and further research to address these disparities and improve outcomes for all populations affected by genitourinary cancers.

RESUMO

Gallbladder cancer (GBC) is a rare and highly aggressive malignancy, often characterized by nonspecific clinical presentations and late diagnosis, which contribute to its poor prognosis. It is commonly detected at advanced stages, leading to low survival rates. Surgical resection is the primary treatment, with the extent of surgery depending on the T stage of the cancer. In advanced cases, surgery is only considered if it can potentially be curative. Despite various treatment approaches for advanced GBC, survival outcomes remain poor. In our case series, we introduce a novel treatment approach combining cytoreductive surgery, intraoperative radiation therapy, and hyperthermic intraperitoneal chemotherapy. Remarkably, we observed a 100% one-year survival rate, with one patient achieving eight years of disease-free survival without recurrence or metastasis. This aggressive treatment strategy did not lead to increased morbidity or mortality, suggesting its safety and feasibility. However, larger-scale studies are required to draw definitive conclusions.

RESUMO

INTRODUCTION: Pheochromocytomas are rare catecholamine-secreting tumors with a high potential for recurrence post-surgery, necessitating prolonged follow-up. This case highlights the diagnostic and therapeutic challenges in managing recurrent pheochromocytoma. CASE PRESENTATION: A 25-year-old female, with a history of left pheochromocytoma treated with adrenalectomy a decade earlier, presented with a right adrenal mass. Despite controlled hypertension, elevated urine metanephrines suggested recurrence. Imaging showed a right adrenal mass and suspicious left paraaortic lymph nodes, confirming the diagnosis of recurrent malignant pheochromocytoma in the left adrenal bed and right adrenal gland, with metastasis to the paraaortic lymph nodes. The patient underwent right adrenalectomy coupled with cytoreductive surgery (CRS) in the form of excision of left-sided adrenal bed recurrence and left paraaortic lymph node dissection, intraoperative radiation therapy (IORT), and hyperthermic intraperitoneal chemotherapy (HIPEC). On follow-up six years later, the patient remains free from recurrence. DISCUSSION: This case illustrates the importance of continued surveillance in pheochromocytoma patients, even those with a low-risk profile. The recurrence in this case, despite a smaller initial tumor size and no genetic predispositions, underscores the unpredictable nature of pheochromocytomas. The successful management with CRS, IORT, and HIPEC emphasizes the need for a personalized and multifaceted treatment approach. CONCLUSION: Pheochromocytoma patients, including those initially considered low risk, require long-term monitoring due to the risk of recurrence. The utilization of CRS, IORT, and HIPEC in this case was pivotal in managing the recurrent and metastatic malignant disease effectively, demonstrating the significance of a comprehensive, multidisciplinary treatment strategy in such complex cases.

RESUMO

Ancient schwannomas are a rare variation of schwannomas, with the distinction being based on histopathological examination of the excised specimen. On histopathological examination, ancient schwannomas exhibit degenerative changes such as calcification, hyalinization, and cystic necrosis, along with S100 positivity. Complete surgical excision is the mainstay treatment for ancient schwannomas and carries a favorable prognosis. Recurrence is the most common complication, often arising from incomplete surgical excision. Herein, we present a case of a 41-year-old male who presented to our center as a case of a retroperitoneal mass for further investigations and diagnostic workup. Imaging showed a retroperitoneal mass in the right iliac fossa. We proceeded with ultrasound guided needle biopsy, and examination of the specimen confirmed the diagnosis of ancient schwannoma. Subsequently, the patient underwent surgery, and complete surgical excision was achieved. On follow-up 3-months later, the patient is doing well, and no signs of recurrence were found.

RESUMO

BACKGROUND: Chronic subdural hematoma (CSDH) is a frequently encountered neurosurgical disease among the elderly. The mainstay treatment involves surgical evacuation, but recurrence rates of approximately 13% pose complications. Adjuvant treatments, including tranexamic acid (TXA), have been explored, yet consensus on their efficacy and safety in elderly patients remains uncertain. The study aims to examine the role of TXA as adjunctive therapy in reducing CSDH recurrence and explore any potential association between TXA use and thrombotic events in this patient population. METHODS: The systematic review and meta-analysis adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and Cochrane Handbook standards, searching databases up to July 2023 for randomized controlled trials and propensity-matched cohorts evaluating adjuvant TXA. The primary outcome was CSDH recurrence, and the secondary outcome was thrombosis risk, measured as relative risks. RESULTS: A total of 6 studies were included, comprising 1403 patients with CSDH who underwent surgical treatment. Four studies were randomized controlled trials, while the other 2 were propensity-matched cohorts. The overall pooled relative risk for CSDH recurrence in the TXA group compared to the control group was 0.41 (95% confidence interval [0.29-0.59], P < 0.01), indicating a significant reduction in recurrence with TXA treatment. CONCLUSIONS: In conclusion, our study indicates that adjuvant TXA may help reduce CSDH recurrence in elderly patients undergoing surgical treatment. However, the study has limitations and there is a need for further research to validate these findings.

RESUMO

BACKGROUND Malignant mesotheliomas are rare, yet highly malignant tumors. Mesotheliomas are tumors that develop from mesothelial surfaces, with the pleura being the most common, followed by the peritoneum. The diagnosis of malignant peritoneal mesothelioma (MPM) is usually established when the disease is advanced, owing to the nonspecific clinical appearance and abdominal symptoms. Initially, MPM was treated with palliative systemic chemotherapy, with or without palliative surgery. However, cytoreductive surgery (CRS) combined with bidirectional intraoperative chemotherapy (BDIC) has recently emerged as a treatment option for MPM. BDIC creates a bidirectional chemotherapy gradient in the peritoneal tumor cells through the simultaneous use of intraperitoneal and intravenous chemotherapy. CRS, combined with BDIC (CRS-BDIC), allows the complete elimination of residual tiny tumor cells after complete removal of the visible tumor nodules. CASE REPORT Herein, we present a case of a 51-year-old woman with MPM and chronic kidney disease (CKD) stage 3b. Her treatment consisted of neoadjuvant chemotherapy and immunotherapy, followed by CRS-BDIC using intraperitoneal cisplatin and doxorubicin, and intravenous ifosfamide. The surgery was successful, with no immediate complications or decline in the patient's kidney function. On follow up 2 months later, the patient denies suffering any chemotherapy-related adverse effects, and her kidney profile remains stable. CONCLUSIONS In conclusion, nephrotoxicity, a known adverse effect of cisplatin and ifosfamide, might not be a contraindication for the use of these potentially nephrotoxic drugs in CRS-BDIC in patients with renal impairment.

RESUMO

Parathyromatosis is a rare cause of recurrent primary hyperparathyroidism that often follows surgical removal of the parathyroid gland. Foci of parathyromatosis are most commonly found in the neck, mediastinum, and sites of autotransplantation. A 36-year-old male with renal failure and prior parathyroidectomy presented with generalized bone pain, for which laboratory investigations revealed hyperparathyroidism. Preoperative coil localization was utilized followed by thoracoscopy using fluoroscopy for resection of ectopic parathyroid tissue. The specimen was sent to histopathology, which revealed multiple nodules of hypercellular parathyroid tissue, consistent with the diagnosis of parathyromatosis. Parathyromatosis is a rare cause of recurrent hyperparathyroidism, with surgical removal being the only curative option. Follow-up is essential as it can commonly recur.
