Surgical management with radiation therapy for metastatic spinal tumors located on cervicothoracic junction : a single center study

Determinação da capacidade de acesso anterior à coluna cervicotorácica conforme idade e gênero: Análise radiográfica de imagens de tomografia computadorizada

Objetivo A capacidade de acesso anterior à região cervicotorácica com base na idade e gênero do paciente e a possibilidade de variações anatômicas em diferentes populações geográficas ainda não foram investigadas. O objetivo deste trabalho foi realizar uma análise radiográfica de pacientes brasileiros para avaliar a acessibilidade anterior da junção cervicotorácica conforme idade e gênero.

Métodos Análise radiográfica retrospectiva de 300 tomografias computadorizadas. Os pacientes foram separados por idade e gênero. Os parâmetros radiográficos estudados foram: nível horizontal acima do esterno (HLS, na sigla em inglês), angulação do corpo vertebral (VBA, na sigla em inglês), linha do disco intervertebral (IDL, na sigla em inglês) e angulação da linha do disco intervertebral (IDLA, na sigla em inglês).

Resultados Os HLS e IDL mais frequentes foram T2 (34,3%) e C7–T1 (46%), respectivamente. Os valores médios de VBA e IDLA foram de 18 ± 8,94 e 19 ± 7,9 graus, respectivamente. Os homens apresentaram valores maiores de IDLA (p = 0,003) e VBA (p = 0,02). Os grupos de maior idade apresentaram valores maiores de IDLA (p = 0,01) e VBA (p = 0,001). Não houve diferenças de HLS entre os gêneros masculino e feminino (p = 0,3) ou faixas etárias (p = 0,79). Não foram observadas diferenças na IDL entre os gêneros masculino e feminino (p = 0,3); entretanto, o grupo mais velho apresentou nível mais caudal do que os grupos mais jovens (p = 0,12).

Conclusões Em comparação a outras populações, nossa amostra apresentou IDL e HLS mais cefálicos. AVBA e a IDLA foram maiores no gênero masculino, enquanto VBA e IDLA foram maiores em grupos mais velhos. A IDL era mais caudal em pacientes idosos.

Reverse "L" surgical approach for the management of giant tumors of the cervicothoracic junction

Background

An isolated cervical or thoracic surgical approach provides insufficient exposure for achieving complete resection of tumors of the cervicothoracic junction. This study examines reverse “L” thoracotomy as a surgical approach to these tumors. Additionally, the feasibility, safety, and effectiveness of reverse “L” surgical incision for tumor resection was also analyzed.

Methods

Patients with cervicothoracic tumors were identified from an internal database. Subjects were selected on the basis of undergoing reverse “L” thoracotomy from August 2014 to August 2018. The tumor characteristics, surgical technique, completeness of resection, morbidity, and patient outcome were reviewed.

Results

All patients successfully underwent resection through reverse “L” surgical approach. No patients needed to undergo full sternotomy. There were 6 neurogenic tumors, 4 thyroid adenocarcinomas, 4 bronchogenic tumors, and 7 other cases in the study. The median operative time was 191.0 min (range, 113.0–348.0 min) and postoperative in-hospital stay ranged from 3 to 7 days. Horner syndrome was observed in 1 case. Hoarseness and lymphatic leakage were evident in 3 and 1 case(s), respectively. Hemidiaphragm paralysis was observed in 1 case. Three cases were unsuccessful in achieving R0 resection. The duration of follow-up ranged from 6 to 42 months. Eleven of 13 patients who underwent resection had no evidence of tumor recurrence. Two patients with metastatic disease died of distant progression within 15 months.

Conclusions

Applying reverse “L” surgical approach is safe, feasible, and effective for the resection of giant tumors of the cervicothoracic junction.

Practicality of using the figure-of-eight bandage to prevent fatal wound dehiscence after spinal tumor surgery for upper thoracic metastasis

OBJECT

Serious postoperative wound problems can frequently develop after surgery with perioperative RT for upper thoracic metastatic lesions. The figure-of-eight bandage can restrict excessive shoulder motion, which could prevent wound dehiscence. The purpose of this study was to describe the efficacy of using the figure-of-eight bandage to prevent postoperative wound dehiscence.

METHODS

Between February 2005 and July 2015, we retrospectively evaluated the medical records of cancer patients who underwent surgery with or without RT for spinal metastasis involving the upper thoracic spine. From January 2009, all patients received figure-of-eight bandaging immediately postoperatively, which was then maintained for 2 months. The outcome measures were the incidence and successful management of wound dehiscence following application of the figure-of-eight bandage.

RESULTS

One hundred and fifteen patients (71 men and 44 women) were enrolled in the present study. A figure-of-eight bandage in conjunction with a thoracolumbosacral orthosis (TLSO) was applied to 78 patients, while only TLSO was applied to 37 patients. The overall rate of wound dehiscence was 4.34% and the mean duration before wound dehiscence was 27.0 days (range, 22-31 days) after surgery. In the TLSO-only group, wound dehiscence occurred in four patients (10.81%), meanwhile there was only one case (1.33%) of wound dehiscence in the group that had received the figure-of-eight bandage with TLSO. Three of four patients with wound dehiscence in the TLSO only group died from unresolved wound problems and another patient was treated with wound closure followed by the application of the figure-of-eight bandage. The only patient with wound dehiscence among the patients who received both the figure-of-eight bandage and TLSO was managed by primary wound closure without further complication.

CONCLUSION

Current study suggests that the figure-of-eight bandage could prevent wound dehiscence and be used to treat wound problems easily.
