The value of multidisciplinary team (MDT) management in the diagnosis and treatment of primary intrathoracic synovial sarcomas: a single-center experience

Epidemiological trends of synovial sarcoma by primary tumor sites in the US from 2000 to 2020

BACKGROUND

Synovial sarcoma (SS) is a rare soft-tissue cancer. Existing literature encompasses Surveillance, Epidemiology, and End Results (SEER) data-based research on SS explaining the incidence-prevalence in general, by subtypes, and by age at diagnosis. Therefore, this study aimed to fill in the gap of knowledge about measures of disease occurrence and burden of SS by tumor site using the SEER database.

METHODS

In this cross-sectional study, primary SS patients were selected from SEER 17 Registries, Nov. 2021 (2000-2020) using ICD-O-3 codes 9040, 9041, 9042, and 9043. Patients with additional cancers were excluded. The primary tumor site was categorized into (1) head/neck, (2) internal thorax, (3) abdomen/pelvis, (4) upper extremity, and (5) lower extremity using ICD-10CM codes. Five outcomes were analyzed: age-adjusted incidence rate, 5-year limited-duration prevalence rate, incidence-based mortality, case-fatality rate, and overall survival.

RESULTS

From 2000-2020, the overall age-adjusted incidence rate was 0.15 per 100,000; the 5-year limited duration prevalence rate was 0.56 per 100,000; and the incidence-based mortality rate was 0.06 per 100,000 people. The case-fatality and 5-year OS rates were 39.2 % and 62.9 %, respectively. Lower extremity had the highest incidence of 0.07 (estimated 1166 cases), prevalence of 0.36 (estimated 224 cases), and mortality rate of 0.025 (estimated 429 deaths) per 100,000. The other four locations had much closer rates with each other. Intrathoracic SS had the highest case-fatality rate of 71.5 % (148/207) and lowest 5-year OS of 26.0 % (95 % CI: 19.6 %, 32.9 %) than other sites.

CONCLUSION

Based on the measures of disease frequency, the most common primary tumor site is the lower extremity, followed by the upper extremity, abdomen/pelvis, internal thorax, and head/neck. The least favorable primary location is the internal thorax. Those with a primary location of the upper extremity have the longest overall survival, followed by the head/neck, lower extremity, abdomen/pelvis, and internal thorax.

A rare case of a young man with mediastinal synovial sarcoma

Synovial sarcoma is a rare and aggressive tumor that primarily affects soft tissues, including the mediastinum, and predominantly affects younger adults. A 23-year-old male patient with mediastinal synovial sarcoma underwent debulking surgery and received 3 cycles of doxorubicin, ifosfamide, and mesna chemotherapy. Mediastinal synovial sarcoma presents diagnostic challenges and poor prognosis. Treatment involves surgical resection, adjuvant chemotherapy, and radiotherapy. Mediastinal synovial sarcoma can be diagnosed through histopathological and immunohistochemical examination. Adjuvant chemotherapy led to a partial response, showing a decrease in tumor size and resolution of pleural effusion, demonstrating a positive interim outcome.

Primary pulmonary monophasic synovial sarcoma initially presenting with bloody pleural effusion: A case report and literature review

Key Clinical Message

Primary pulmonary synovial sarcoma (PPSS) can originate from blood vessels of the bronchial wall, lung interstitium, and interstitial components, and accounts for 0.1%-0.5% of all primary lung malignancies, the most common symptoms are chest pain, cough, dyspnea, and hemoptysis.

Abstract

Synovial sarcoma (SS) is a rare malignant tumor of stromal origin, which accounts for approximately 8%-10% of all soft tissue sarcomas. Primary pulmonary synovial sarcoma (PPSS) can originate from blood vessels of the bronchial wall, lung interstitium, and interstitial components, and accounts for 0.1%-0.5% of all primary lung malignancies. Patient concerns: We report the first case of a 57-year-old man with bloody pleural effusion as an initial manifestation of PPSS in the middle lobe of the right lung diagnosed after surgery. Diagnosis: Chest computed tomography (CT) revealed a mass in the middle lobe of the right lung, which was pathologically diagnosed as a monophasic SS after surgical resection. Interventions: Ten days after preoperative closed chest drainage, a right thoracotomy was performed to remove the right middle lobe of the lung. Outcomes: The patient recovered smoothly and was discharged from the hospital without any other postoperative treatment. A follow-up chest CT scan 7 months postoperatively revealed intrapulmonary recurrence with multiple metastases. Lessons: Monophasic PPSS of the lung may present with bloody pleural effusion as its first manifestation.

Multidisciplinary management of recurrent synovial sarcoma of the chest wall

Background

Synovial sarcoma (SS) is part of soft tissue sarcomas (STS). An incidence between 5% to 10% is estimated. The origin is mesenchymal mainly affecting the extremities. Being even rarer at the chest level and vertebral body, representing around 1%. Histologically, it consists of 3 variants: monophasic, biphasic, and poorly differentiated. Surgical resection is a priority when it comes to multidisciplinary management. The prognosis of patients with SS over the years has improved markedly.

Purpose

Understand and evaluate the multidisciplinary management of SS considering that the SS has a lowe prevalence and highly malignancy.

Study Design

We present a case of a 31-year-old male who has a history of monophasic synovial sarcoma diagnosed in 2019 and underwent surgery. Patient came back after two years without symptoms and posterior to a control MRI we observed a local recurrence of SS.

Methods

The literature was reviewed with a focus on best clinical and surgical strategy for recurrence of SS.

Results

The patient recovered well with return to his normal daily activities. The review of the literature shows us the importance of the multidisciplinary management for the optimal clinical and surgical approach of SS recurrence.

Conclusions

SS represents a unique variant of STS, with malignant and metastatic potential. Being a rare pathology, an adequate multidisciplinary management is essential when providing optimal care for the patient.

Application Analysis of Multidisciplinary Diagnosis and Treatment Nursing Mode Based on Doctor-Nurse-Integration for Stroke Patients Undergoing Emergency Intervention Surgery

Purpose

To analyze the application value of multidisciplinary diagnosis and treatment (MDT) nursing mode based on doctor-nurse-integration for stroke patients undergoing emergency intervention surgery.

Methods

In this study, a historical comparative study method was adopted. 118 stroke patients and medical staff (9 doctors and 11 nurses) who met the diagnosis and inclusion criteria of emergency intervention surgery admitted from July 2021 to February 2022 were treated clinically according to the traditional medical care mode (TMC group), 87 stroke patients and medical staff (9 doctors and 11 nurses) who met the diagnosis and inclusion criteria of emergency intervention surgery admitted from February 2022 to June 2022 were treated and cared according to the MDT nursing mode based on medical integration (MDT group). Comparison of perioperative time indicators, postoperative outcome indicators, treatment compliance, secondary complications and visit satisfaction between the two groups of patients, and comparison of cooperation satisfaction between the two groups of medical staff.

Results

The MDT group had shorter onset-emergency physician's reception time, arrival at CT room-completion time of CT/MR, notify intervention chamber-arrival time at catheter chamber, admission-femoral artery puncture time, admission-first vessel recanalization time, mean postural restraint time than the TMC group (P < 0.05). The postoperative mortality rate in the MDT group (5.75%) was comparable to that in the TMC group (8.47%) (P > 0.05); the postoperative disability rate in the MDT group (28.74%) was less than that in the TMC group (45.76%) (P < 0.05); the NIHSS score in the MDT group was lower than that in the TMC group, and the FMA score and BI score were both higher than those in the TMC group (P < 0.05). The MDT group had higher treatment compliance than the TMC group, fewer secondary complications than the TMC group, and higher patient visit satisfaction and medical staff cooperation satisfaction than the TMC group (P < 0.05).

Conclusion

The implementation of the MDT nursing mode based on the doctor-nurse-integration for stroke patients undergoing emergency intervention surgery can improve the work efficiency of rescuing patients, improve the clinical treatment outcome of patients, and improve the satisfaction of doctors, nurses, and patients.

Perioperative anesthesia management in pediatric liver transplant recipient with atrial septal defect: A case report

BACKGROUND

Preoperative conditions in pediatric liver transplant recipients are understandably complex. Compared with adults, children have lesser compensatory abilities and demand greater precision during procedural executions. In the setting of end-stage liver disease, the heightened perioperative risk of coexistent cardiovascular pathology may impact graft survival as well. Requirements for anesthesia and perioperative management are thus more rigorous, calling for individualized treatments that reflect specific cardiovascular constraints and proposed surgical plans.

CASE SUMMARY

Reports of perioperative anesthesia management and liver transplant prognostication in pediatric patients with concurrent atrial septal defects are scarce. Herein, we detail the course of liver transplantation in a child with dual afflictions, focusing on perioperative anesthesia management and the important contributions of the anesthesiologist (pre- and perioperatively) to a positive therapeutic outcome, despite the clinical hurdles imposed.

CONCLUSION

Children with atrial septal defects bear substantially more than customary perioperative risk during orthotopic liver transplants, given their compromised cardiopulmonary reserves and functional states. Comprehensive preoperative cardiovascular assessments, including use of agitated-saline contrast echocardiography (to characterize intracardiac shunting) and multidisciplinary deliberation, may offer insights into structural cardiac pathophysiologic effects and transplant-related hemodynamic changes that impact new grafts. At the same time, active and effective monitoring and other measures should be taken to maintain hemodynamic stability in the perioperative period, avoid entry of bubbles into the circulation, and ease congestion in newly grafted livers. Such efforts are crucial for transplantation success and graft survival.
