RESUMO

Background: The management of vestibular schwannoma has evolved over the past hundred years. In the last decades, surgery has been gradually replaced by radiation therapy as a primary treatment modality, particularly for small tumors, due to the less invasive nature and the compared reported outcomes in tumor control and hearing preservation. However, irradiation sometimes fails to stop tumor growth. In a long-term follow-up after primary fractionated stereotactic radiotherapy, the rate of treatment failure was reported as 3% and needed surgical salvage. For single-fraction modality, Hasegawa et al. reported salvage treatment after primary Gamma Knife radiosurgery in 8%, where 90% of these underwent surgery and 50% of those who were treated with a second gamma knife surgery required surgical intervention later. An increase in tumor volume by more than 10-20%, tumor growth after three years, and no return to pretreatment volume after transient swelling have been considered as tumor recurrence rather than pseudoprogression, a transient increase in tumor volume after radiotherapy that occurs up to 30% of cases. It has been reported that microsurgery after radiotherapy is more difficult, with most authors reporting a loss of defined arachnoid planes and worse cranial nerve outcomes, especially for hearing and facial nerve function. Case Description: A 43-year-old female patient was incidentally (asymptomatic) diagnosed on a magnetic resonance imaging (MRI) scan harboring a left vestibular schwannoma, grade T2 (Hannover classification), in 2015. Neurologic examination was unremarkable, and audiometry testing was normal. She was initially treated with observation. Three years later, in 2018, the lesion had enlarged, becoming a grade T3a and reaching the cistern of the cerebellopontine angle. The tumor was then treated with fractionated stereotactic radiosurgery (5 sessions of 5 Gy). MRI scans in 2019 and 2020 showed slight tumor growth. This enlargement was attributed to a pseudoprogression after radiosurgery, and only observation was advocated. In 2022, 4 years later, after radiosurgery, the tumor was still growing, and the patient began to suffer from hearing loss. A failure treatment was considered, and microsurgery was indicated. The patient was counseled about the risk of functional nerve impairment, and surgical consent was obtained. A retro sigmoid approach was planned. A gross total resection was attempted due to the clear subperineural plane during tumor dissection and because it was the only option that would provide a cure for the patient. The adjacent neurovascular structures were firmly adhered to the tumor capsule, which represented a major challenge for microdissection. The tumor was soft, without significant bleeding. A total resection was achieved, and the facial nerve was anatomically preserved. The patient developed facial paresis (House-Brackmann III) in the immediate postoperative period, which improved at the 6-month follow-up. Hearing loss did not improve. Postoperative MRI showed total resection. Conclusion: Microsurgery after radiotherapy for vestibular schwannoma is challenging in terms of indication, when to indicate, resection target, difficulty in dissection due to local changes, and outcome. Gross total resection may be considered, as it is the only treatment that may provide a cure for the patient. However, the patient should be counseled about the risks.

RESUMO

El siguiente caso, se trata de una paciente de sexo femenino que acude a consulta de traumatología por dolor de rodilla y dificultad para deambular, sin antecedente de trauma. En la radiografía anteroposterior y lateral se evidencia múltiples áreas radiolúcidas y escleróticas en meseta tibial y fémur distal derecho. La biopsia reporta: Condrosarcoma indiferenciado Grado 2. Se inicia sesiones de quimioterapia profiláctica y se planifica la cirugía de salvamento, esto ante la negativa de la paciente para aceptar la cirugía de amputación. La cirugía de reconstrucción se realizó mediante la colocación de una prótesis semiconstreñida tipo Endo Model cementada. En el posoperatorio se realizó controles y curaciones semanales, con buena cicatrización de la herida, y posteriormente rehabilitación por fisioterapia. Actualmente la paciente puede deambular con apoyo y casi de manera independiente.

RESUMO

La recurrencia de carcinoma de células escamosas orofaríngeo (CCEOF) se asocia a mal pronóstico, particularmente en recurrencias en etapa avanzada. La cirugía en el contexto de rescate es más complicada por el tratamiento oncológico del tumor primario, por lo tanto, tiene un mayor riesgo de complicaciones y estadía hospitalaria. Sin embargo, la cirugía de rescate es la mejor oportunidad del paciente como tratamiento curativo y para supervivencia a largo plazo. La población de pacientes que reciben tratamiento para CCEOF ha cambiado en la última década, se ha reconocido que la incidencia de virus papiloma humano (VPH) asociado a CCEOF ha generado el gran aumento de CCEOF y el cambio asociado en las características de la población de pacientes, ahora los pacientes son más jóvenes y tienen menos comorbilidades. Con el aumento exponencial en la incidencia de CCEOF, la necesidad de cirugía de rescate en CCEOF podría verse en aumento. En vista del aumento de la incidencia de casos con carcinoma escamoso de orofaringe y su importante relación con el VPH, esta revisión se enfoca en la supervivencia tras cirugía de rescate con intención curativa y evaluar si con los avances en su tratamiento ha mejorado su pronóstico.

Recurrence of oropharyngeal squamous cell carcinoma (OPSCC) is associated with poor prognosis, particularly in advanced stage recurrences. Salvage surgery is complicated by previous oncological treatment of the primary tumor, therefore, it has a higher risk of complications and hospital stay. However, salvage surgery is the patient's best opportunity as a curative treatment and for long-term survival. The population of patients receiving treatment for OPSCC has changed in the last decade, it has been recognized that the incidence of human papilloma virus (HPV) associated OPSCC has generated an increase of OPSCC and changes in the epidemiology of the patient population, with younger patients and with less comorbidities. With the exponential increase in the incidence of OPSCC, the need for salvage surgery in OPSCC could increase in the future. In view of the increase in the incidence of cases with squamous oropharyngeal carcinoma and its relationship with HPV, this review focuses on survival after salvage surgery with curative intent and assessing whether the progress in its treatment has improved its prognosis.

RESUMO

INTRODUCTION: In patients with unresectable Differentiated thyroid cancer (DTC), the use of external beam radiation therapy (EBRT), leads mostly to palliation. Our aim is to define the role of upfront EBRT, followed or not by salvage surgery, on Progression-free survival (PFS) or Overall survival (OS) in patients with DTC. METHODS: This is a cohort study of patients with initially unresectable DTC who received EBRT. Cohort A received EBRT followed by rescue surgery and cohort B, EBRT only. The Kaplan-Meier method and Cox model were employed for survival analysis. RESULTS: Thirty-three patients were included; 69.6% females and 30.3% males. Mean age was 60.6 and mean tumor diameter was 10.4 cm; 17 and 16 patients were included in cohorts A and B, respectively. Belonging to cohort A (Hazard ratio [HR] 0.177, 95% CI 0.05-0.7) and use of intensity modulated radiotherapy (HR 0.177, 95% CI 0.03-1.08) were associated to better PFS, while high-risk histopathology (HR 6.6, 95% CI 0.9-50) and EBRT dose (HR 1.05, 95% CI 1.01-1.08) were independently associated with lower PFS. Patients from cohort A (HR 0.061, 95% CI 0.01-0.3) had improved OS, while high-risk histopathology (HR 5.7, 95% CI 1.1-28.6) and EBRT dose (HR 1.05, 95% CI 1.01-1.09) were independently associated to worse OS. CONCLUSION: EBRT, and when feasible, salvage surgery, should be an integral part of the therapeutic strategy in initially unresectable DTC.

RESUMO

PURPOSE: Transoral robotic surgery (TORS) is one of the main treatment options for non-locally advanced primary oropharyngeal cancer in the United States. However, its use is more limited in countries with a low incidence of human papillomavirus (HPV), such as Spain, in patients with advanced disease, and as salvage surgery. To shed light on the use and potential benefit of TORS in Spanish patients, we analyzed the functional and oncologic outcomes of TORS as both primary and salvage surgery in a primarily HPV-negative population which is representative of oropharyngeal squamous cell carcinoma (OPSCC) patients in Spain. MATERIAL AND METHODS: This is a retrospective analysis of prospectively collected data on OPSCC patients treated with TORS at our center between February 2017 and February 2019. RESULTS: Fifty-four OPSCC patients were included; 79.6% were males and 80.5% were HPV negative. Median age was 62 years. Primary surgery was performed on 73.7% (48.1% stage I-II; 51.9% stage III-IV) and salvage surgery on 25.9% of patients. Positive margin rates were 4.3% for T1-2 and 25.8% for T3-4. None of the stage I-II patients and 27.7% of stage III-IV patients required adjuvant treatment. Reconstructive surgery was performed in 19.2% of all patients. Normal swallowing was achieved in 92.7% of patients at 6 months after surgery. 1- and 2-year survival rates for all patients were 94.5% and 89%, respectively. The overall complication rate was 16.1%. Bleeding occurred in 11.5% of patients. Longer hospitalization time was associated with surgical complications (P = 0.03) and reconstructive surgery (P = 0.03) but not with salvage surgery. CONCLUSION: TORS is a safe and effective treatment for HPV-negative T1-2 OPSCC patients. The positive margin rate was worse in T3-4 patients, indicating the need for careful patient selection in this subgroup.

RESUMO

OBJECTIVE: Salvage surgery (SS) for penile cancer (PC) is indicated in the management of local failure following radiation therapy (RT). Reports describing survival outcome are rare. This study aims to assess survival outcome of SS following RT failure in PC. MATERIALS AND METHODS: We used The Surveillance, Epidemiology, and End Results database to identify patients received SS on the penis following RT. Social, demographic and pathological criteria of the patients were gathered. The 1-, 3-, 5-, 10-year survival rates were assessed. RESULTS: Between 1976 and 2013, 17 patients received penile SS following RT. Median age was 65 years (range 47-91 years). The mean follow-up was 51 months (range 3-213 months). Sixteen (94.12%) patients received external beam radiation and 1 (5.88%) received combined external beam radiation with brachytherapy. Tumor histology was squamous cell carcinoma in 16 (94.12%) patients and mucinous adenocar-cinoma in 1 (5.88%). The 1-, 3-, 5- and 10-year overall survival rates were 68.8, 35.7, 35.7 and 10.7%, respectively. The 1-, 3-, 5- and 10-year cancer specific survival rate was 72.7, 48.4, 48.4, and 36.3% respectively. CONCLUSION: Our results demonstrate, the overall survival of PC patients underwent SS was poor with nearly one third of patients dying within the first year and only one third surviving up to 3 years from the SS.

RESUMO

BACKGROUND: Patients with recurrent retroperitoneal and pelvic region tumors often require multimodal therapies. Intraoperative radiation therapy (IORT) can deliver high-dose radiation to tumor beds, even if first-line external beam radiation therapy (EBRT) was administered. We evaluated local control (LC) and survival in patients receiving IORT for recurrent tumors. METHODS: We retrospectively analyzed 41 patients with isolated pelvic or retroperitoneal recurrences of colorectal, gynecological, or retroperitoneal primary tumors. Following salvage surgery, all patients underwent tumor bed IORT via electron beam or high dose rate brachytherapy. Isolated IORT (median dose: 15 Gy) was administered to patients who had received first-line EBRT; other patients received IORT (median dose 12 Gy) plus EBRT. Local (LF), regional (RF), and distant failures (DF) were evaluated, and the Kaplan-Meier method and log-rank test were used to evaluate and compare overall survival (OS) from the date of IORT. RESULTS: Forty-one patients underwent 44 treatments, including 27 (61.3%) isolated IORT and 17 (38.7%) IORT and EBRT combination regimens. The median follow-up was 8.1 years (range: 4.4-11.7 years), and the 2, 5, and 8 year overall LC rates were 87.9, 64.0, and 49.8%, respectively. Regarding resection status, the respective 2, 5, and 8 year LC rates were 90, 76, and 76% for R0 resection and 75, 25, and 0% for R1 resection (p < 0.001). The 2, 5, and 8 year OS rates were 68, 43, and 26%, respectively. OS was better among patients with LC (p < 0.001). Twenty-four patients (58.5%) experienced a DF, and the 5 year OS rates for the patients with and without DF were 36 and 52%, respectively (p = 0.04). In a multivariate analysis, LF (p = 0,012) and recurrent retroperitoneal sarcoma (p = 0,014) were identified as significant predictors of worse OS. Thirteen patients (31%) developed clinically treatable complications related to IORT. CONCLUSIONS: Many patients achieve long-term OS and LC without significant morbidity after salvage surgery and IORT, especially in case of clear margins.

RESUMO

BACKGROUND: Synchronous liver metastases (LM) from gastric (GC) or esophagogastric junction (EGJ) adenocarcinoma are a rare events. Several trials have evaluated the role of liver surgery in this setting, but the impact of preoperative therapy remains undetermined. METHODS: Patients with synchronous LM from GC/EGJ adenocarcinoma who achieved disease control after induction chemotherapy (ICT) and were subsequently scheduled to chemoradiotherapy (CRT) to the primary tumor and surgery assessment were retrospectively analyzed. Pathological response, patterns of relapse, progression-free survival (PFS), and overall survival (OS) were calculated. From July 2002 to September 2012, 16 patients fulfilling the inclusion criteria were identified. RESULTS: Primary tumor site was GC (nine patients) or EGJ (seven patients). LM were considered technically unresectable in nine patients. Radiological response to the whole neoadjuvant program was achieved in 13 patients. Eight patients underwent surgical resection of the primary tumor; in five of these LM were resected. A complete pathological response in the primary or in the LM was found in four and three patients, respectively. The most frequent site of relapse/progression was systemic (eight patients). Local and liver-only relapses were observed in two patients each. After a median follow-up of 91 months, the median OS and PFS were 23.0 (95% CI 13.2-32.8) and 17.0 months (95% CI 11.7-22.3). 5-year actuarial PFS is 17.6%. CONCLUSION: Our results suggest that an intensified approach using ICT followed by CRT in synchronous LM from GC/EGJ adenocarcinoma is feasible and may translate into prolonged survival times in selected patients.

RESUMO

PURPOSE: We propose to study a group of patients with primary bone sarcoma of the pelvis treated with limb salvage surgery and analyze overall survival, local recurrence rates and functional outcomes. METHODS: A retrospective review was performed, and all patients diagnosed with pelvic primary bone sarcomas between 1990 and 2012 were analyzed. Patients treated with limb salvage surgery and with a minimum of 12-month follow-up for patients alive were included. The overall survival and the local recurrence rate were calculated for the assessment of oncological results. The associations with gender, age, histological grade, type of surgery, margins chemotherapy response and use of navigation were examined. RESULTS: Fifty-two patients were included in the study. The mean age was 37 years (range 10-82), and mean follow-up was 44 months (range 8-189). Forty-five (86 %) tumors were histologically classified as high-grade sarcomas, four (8 %) as low-grade sarcomas and three (6 %) as dedifferentiated sarcomas. Cancer-specific overall survival was 37.5 % for 5 years and 31 % for 10 years. Local recurrence rate was 30 %. High-grade tumors and chemotherapy necrosis below 90 % were negative prognosis factor. Postoperative complication rate was 34.5 % (n:18), being deep infection the most prevalent (n:13). Reconstruction of the pelvis after an oncology resection for primary pelvic sarcomas increased the incidence of complication significantly (p < 0.001). CONCLUSION: Primary bone sarcomas involving the pelvis are suggestive of a high-grade tumor and present poor oncologic outcomes. Pelvic reconstruction after a limb salvage surgery is associated with a high risk of complication. LEVEL OF EVIDENCE: Case series, Level IV.

RESUMO

Previo a los años 70, la amputación interescapulotorácica era el principal tratamiento para los tumores óseos malignos de la cintura escapular. Con la mejor comprensión del comportamiento biológico de éstos y aplicación de terapia adyuvante, 80-90% pueden ser resecados con seguridad, empleando procedimientos de salvamento de extremidades. Se trata de paciente masculino de 34 años de edad quien cursa con aumento de volumen en región escapular derecha, de un año de evolución, acompañado de dolor en articulación acromio-clavicular y limitación para movimientos de abducción y flexión. Radiológicamente, se observó área osteolítica en fosa supraespinosa de escápula derecha; la tomografía reveló lesión destructiva de acromio, cabeza humeral y tercio externo de clavícula, en gammagrama óseo: lesión única en escápula derecha; TAC de tórax sin evidencia de lesiones secundarias. Biopsia incisional reportó sarcoma de alto grado clasificado como estadío IIB de Enneking. Posterior a estudio de Angioresonancia, se decidió y realizó la cirugía de salvamento de extremidad denominada Thikoff Lindbergh tipo IVB, consistente en la resección oncológica de margen amplio de escápula, articulación glenohumeral, 2/3 externos de clavícula y 1/3 proximal de húmero derecho. La histopatología determinó bordes libres de enfermedad y el diagnóstico final fue Osteosarcoma de alto grado. Postoperatorio con excelentes resultados; es referido a oncología clínica y a fisioterapia. Aunque los osteosarcomas de huesos planos son relativamente raros, su aparición en huesos como escapula condicionan situaciones de difícil manejo, ya que la resección adecuada está sujeta a un correcto proceso de estadificación y a una técnica depurada y experimentada(AU)

Prior to the 70s, the forequarter amputation was the primary treatment for malignant bone tumors of the shoulder girdle. With better understanding of the biological behavior of these and application of adjuvant therapy, 80-90% can be safely resected using limb salvage procedures. Male patient is 34-year- old who was studying with increased volume in the right scapular region, a year of evolution, accompanied by pain in acromioclavicular joint and limitation of abduction and flexion movements. Radiologically, there was osteolytic area in right supraspinous fossa of scapula; tomography revealed destructive lesion of acromion, humeral head and the outer third of clavicle, in ganmagrama bone: single lesion in right scapula, CT scan without evidence of secondary lesions. Incisional biopsy reported high grade sarcoma classified as Enneking stage IIB. Angiography after study, it was decided and performed limb salvage surgery called Thikoff Lindbergh type IVB, consisting of oncological resection of scapula wide margin, glenohumeral joint, two thirds collarbone external third right proximal humerus. The histopathology determined disease-free edges and the final diagnosis was highgrade osteosarcoma. Postoperative with excellent results, is referred to physiotherapy and clinical oncology. Although osteosarcoma of flat bones are relatively rare, their occurrence in bone and scapula condition unwieldy situations as adequate resection is subject to proper staging process and a refined technique and experienced(AU)

The usual management of upper aero digestive tract squamous cell carcinoma is surgery associated or not to post surgical radiotherapy. Loco-regional relapses constitute the main failure of the initial treatment and early diagnosis justifies the indication of salvage surgery. AIM: Descriptive analysis of demographic data and staging for salvage surgery of oropharynx tumors. MATERIALS AND METHODS: We studied retrospectively 78 patients submitted to surgery in all cases; however, just 37 patients received post surgical radiotherapy. RESULTS: There was a predominance of males in 70 cases, with mean age of 54.2 years, and 54 patients were Caucasian. The patients were classified as T3 and T4 in 38 cases and 40 patients were classified as N0 neck. 35 patients developed loco-regional distant relapses. 17 patients were submitted to salvage surgery and 12 patients were reclassified as T1; 2 patients T2 and in relation to the clinical stage N, 2 patients were N2a and 2 patients N2b. The average age of the patients submitted to salvage surgery was 52.8 years, with predominance of male Caucasians. CONCLUSION: Clinical stage I and II were accorded salvage surgery.

O objetivo do estudo é avaliação da sobrevida livre de doença após resgate cirúrgico de tumores de cavidade bucal e orofaringe. MÉTODOS: Estudo retrospectivo de 276 pacientes tratados com cirurgia, sendo que 127 desenvolveram recidiva loco-regional. Noventa e sete pacientes eram de estadiamento clínico inicial e 178 de estadiamento clínico avançado. Vinte e cinco casos de lábio, 173 cavidade bucal e 78 de orofaringe. A radioterapia pós-operatória foi realizada em 121 pacientes com dose média de 60,8 Gy. RESULTADOS: Oitenta e nove pacientes foram submetidos a tratamento de resgate, sendo que 76 destes foram à cirurgia. As recidivas loco-regionais de cavidade bucal foram submetidas ao resgate cirúrgico em 65 por cento casos. A sobrevida livre de doença pós-cirurgia de resgate foi de 13 por cento nas recidivas até seis meses e 48 por cento nas recidivas após 12 meses de seguimento (p=0,0009). O tipo de resgate e o intervalo livre de doença foram fatores independentes de sobrevida na análise multivariada. CONCLUSÃO: A sobrevida livre de doença pós-resgate nos estadios clínicos iniciais (I e II) foi de 70 por cento.

OBJECTIVE: Salvage surgery is the first therapeutic option for recurrent tumors of the mouth and oropharynx, mainly in early stage tumors. This study intends to evaluate the disease free survival interval after salvage treatment for recurrent tumors of the mouth and oropharynx. METHODS: Retrospective analysis of 276 patients with squamous cell carcinoma of the mouth and oropharynx treated with surgery. One hundred and twenty seven patients developed loco-regional recurrence. Ninety-seven were staged as early tumors and 178 as advanced ones. The tumor site was the lip in 25 cases, oral cavity in 173 and oropharynx in 78. Postoperative radiotherapy was indicated in 121 cases with a mean dose of 60.8Gy. RESULTS: Eighty-nine patients underwent salvage treatment (surgery in 76 patients). Loco-regional recurrences were treated with salvage surgery in 65 percent of cases. Disease free survival after salvage surgery was 13 percent in cases with recurrences diagnosed up to 6 months and 48 percent in those who recurred after 12 months of follow-up (p=0.0009). Modality of salvage treatment and the disease free interval were independent variables of survival in the multivariate analysis. CONCLUSION: In cases clinically staged as I and II, the disease free survival in five years after salvage treatment was 70 percent.
