Available evidence on HIFU for focal treatment of prostate cancer: a systematic review

ABSTRACT Purpose: Prostate cancer (PCa) is the second most common oncologic disease among men. Radical treatment with curative intent provides good oncological results for PCa survivors, although definitive therapy is associated with significant number of serious side-effects. In modern-era of medicine tissue-sparing techniques, such as focal HIFU, have been proposed for PCa patients in order to provide cancer control equivalent to the standard-of-care procedures while reducing morbidities and complications. The aim of this systematic review was to summarise the available evidence about focal HIFU therapy as a primary treatment for localized PCa. Material and methods: We conducted a comprehensive literature review of focal HIFU therapy in the MEDLINE database (PROSPERO: CRD42021235581). Articles published in the English language between 2010 and 2020 with more than 50 patients were included. Results: Clinically significant in-field recurrence and out-of-field progression were detected to 22% and 29% PCa patients, respectively. Higher ISUP grade group, more positive cores at biopsy and bilateral disease were identified as the main risk factors for disease recurrence. The most common strategy for recurrence management was definitive therapy. Six months after focal HIFU therapy 98% of patients were totally continent and 80% of patients retained sufficient erections for sexual intercourse. The majority of complications presented in the early postoperative period and were classified as low-grade. Conclusions: This review highlights that focal HIFU therapy appears to be a safe procedure, while short-term cancer control rate is encouraging. Though, second-line treatment or active surveillance seems to be necessary in a significant number of patients.

Salvage treatment for refractory or relapsed acute myeloid leukemia: a 10-year single-center experience

OBJECTIVES: The outcomes of refractory and relapsed acute myeloid leukemia (AML) patients in developing countries are underreported, even though the similar classic regimens are widely used. METHODS: We conducted a retrospective comparison of "MEC" (mitoxantrone, etoposide, and cytarabine) and "FLAG-IDA" (fludarabine, cytarabine, idarubicin, and filgrastim) in adults with first relapse or refractory AML. RESULTS: In total, 60 patients were included, of which 28 patients received MEC and 32 received FLAG-IDA. A complete response (CR) rate of 48.3% was observed. Of the included patients, 16 (27%) died before undergoing bone marrow assessment. No statiscally significant difference in CR rate was found between the two protocols (p=0.447). The median survival in the total cohort was 4 months, with a 3-year overall survival (OS) rate of 9.7%. In a multivariable model including age, fms-like tyrosine kinase 3 (FLT3) status, and stem-cell transplantation (SCT), only the last two indicators remained significant: FLT3-ITD mutation (hazard ratio [HR]=4.6, p<0.001) and SCT (HR=0.43, p=0.01). CONCLUSION: In our analysis, there were no significant differences between the chosen regimens. High rates of early toxicity were found, emphasizing the role of supportive care and judicious selection of patients who are eligible for intensive salvage therapy in this setting. The FLT3-ITD mutation and SCT remained significant factors for survival in our study, in line with the results of previous studies.

Ventilación no invasiva posextubación en cuidados intensivos pediátricos: estudio multicéntrico / Post-extubation non-invasive ventilation in the pediatric intensive care unit: a multicenter study

Introducción. El fracaso de extubación es una complicación que aumenta la morbimortalidad. La ventilación no invasiva (VNI) demostró ser efectiva como tratamiento de soporte ventilatorio. Objetivo. Determinar la tasa de éxito de la VNI posextubación y los factores asociados al éxito o fracaso del procedimiento. Población y métodos. Diseño: observacional, retrospectivo, analítico y multicéntrico. Ingresaron todos los pacientes que requirieron VNI posextubación durante 2014 y 2015. Se denominó VNI de rescate la implementación por falla respiratoria aguda y VNI electiva, su aplicación en forma profiláctica. Se definió fracaso de la VNI la necesidad de intubación orotraqueal en las primeras 48 horas. Se compararon las características entre éxitos y fracasos, los tipos de VNI y se realizó un relevamiento del equipamiento utilizado. Resultados. Precisaron VNI de rescate 112 niños y VNI electiva, 143. Las tasas de éxitos fueron de 68,8% y 72,7%, respectivamente. Aquellos que fracasaron la VNI de rescate tuvieron una mortalidad mayor que aquellos con VNI exitosa. Se observaron más días de internación y de ventilación mécanica invasiva previa a la extubación en el grupo de VNI electiva. El diagnóstico más frecuente fue la infección respiratoria aguda baja en el niño sano. Conclusiones. La utilización de VNI posterior a la extubación puede ser una herramienta útil para evitar el reingreso a ventilación mecánica invasiva. Los pacientes inmunocomprometidos y con antecedentes neurológicos tuvieron mayor fracaso. Los pacientes que fracasaron toleraron menos horas de VNI y presentaron mayor estadía en la Unidad de Cuidados Intensivos Pediátricos.

Introduction. Extubation failure is a complication that increases morbidity and mortality. Noninvasive ventilation (NIV) has demonstrated to be effective as ventilatory support therapy. Objective. To determine the rate of postextubation NIV success and the factors associated with procedural failure or success. Population and methods. Design: observational, retrospective, analytical, and multicenter study. All patients who required post-extubation NIV during 2014 and 2015 were included. Rescue NIV was defined as the implementation of NIV for acute respiratory failure; elective NIV was described as its implementation for prophylaxis. NIV failure was defined as the need for orotracheal intubation within the first 48 hours. The characteristics of failure and success and the types of NIV were compared, and the equipment used was assessed. Results. Rescue NIV was required in 112 children; elective NIV, in 143. The rates of success were 68.8% and 72.7%, respectively. Mortality was higher among patients in whom rescue NIV failed compared to those with successful NIV. A longer length of stay and more days of invasive mechanical ventilation prior to extubation were observed in the elective NIV group. The most common diagnosis was acute lower respiratory tract infection in previously healthy children. Conclusions. The use of post-extubation NIV may be a useful tool to prevent reintubation with invasive mechanical ventilation. Immunocompromised patients and those with neurological history had a higher rate of failure. Patients with failure tolerated less hours of NIV and had a longer length of stay in the pediatric intensive care unit.

Salvage surgical procedure for artificial sphincter extrusion

ABSTRACT Case Hypothesis: Surgical removal is the standard treatment for artificial sphincter extrusion. However in some specific situations is possible to maintain the prosthesis with good results. Case report: We report a 60 years old patient presenting sphincter pump extrusion one month after artificial urinary sphincter (AUS) AMS 800™ placement for treating post-radical prostatectomy urinary incontinence (PRPUI). He also had a penile pros- thesis implant one year before that was replaced in the same surgery the sphincter was implanted. As patient refused sphincter removal and there were no signals of active infection he was treated by extensive surgical washing with antibiotics and antiseptics. Pump was repositioned in the opposite side of the scrotum. Patient had good evolution with sphincter activation 50 days later. After 10 months of follow up, patient is socially continent and having regular sexual intercourse. Savage surgery may be an option in select cases of artificial sphincter extrusion. Promising future implications: Like in some patients with penile prosthesis some pa- tients with artificial sphincter extrusion can be treated without removing the device. This may be a line of research about conservative treatment of artificial sphincter complications.

High-Intensity Focused Ultrasound (HIFU) as salvage therapy for radio-recurrent prostate cancer: predictors of disease response

ABSTRACT Background Some men with localized radio-recurrent prostate cancer may benefit from salvage high-intensity focused ultrasound (HIFU). Herein, we describe oncologic outcomes and predictors of disease response after salvage whole gland HIFU from our prospective cohort. Materials and Methods Patients with localized radio-recurrent prostate cancer were prospectively enrolled from January 2005 to December 2014. Participants had to meet both biochemical and histological definitions of recurrence. Exclusion criteria included the receipt of prior salvage therapy, presence of metastatic disease, and administration of ADT in the 6-months prior to enrollment. Participants were treated with a single session of whole-gland HIFU ablation with the AblathermTM device (EDAP, France). The primary endpoint was recurrence-free survival (RFS), defined as a composite endpoint of PSA progression (Phoenix criteria), receipt of any further salvage therapy, receipt of ADT, clinical progression, or death. Kaplan-Meier survival analysis was used to determine the primary end-point and stratifications were used to determine the significance of 6 pre-specified predictors of improved RFS (TRUS biopsy grade, number of study entry TRUS biopsy cores positive, palpable disease at study enrollment, pre-HIFU PSA, an undetectable post-HIFU PSA nadir, and receipt of prior hormone therapy). Survival analysis was performed on participants with a minimum of 1-year follow-up. Results Twenty-four participants were eligible for study inclusion with a median follow-up of 31.0 months. Median PSA at study entry was 4.02ng/ml. Median time to PSA nadir was 3 months after treatment and median post-HIFU PSA nadir was 0.04ng/ml. Median 2-year and 5-year RFS was 66.3% and 51.6% respectively. Of our 6 prespecified predictors, an undetectable PSA nadir was the only significant predictor of improved RFS (HR 0.07, 95% CI 0.02-0.29, log-rank P<0.001). One participant underwent an intervention for a urethral stricture. No participants developed osteitis pubis or rectourethral fistulae. Conclusions Salvage HIFU allows for disease control in selected patients with localized radio-recurrent prostate cancer. An undetectable PSA nadir serves as an early predictor of disease response.

Hypofractionated Re-irradiation after Maximal Surgical Resection for Recurrent Glioblastoma: Therapeutic Adequacy and Its Prognosticators of Survival

PURPOSE: To evaluate the adequacy of retreatment, including hypofractionated re-irradiation (HFReRT), after surgery for recurrent glioblastoma (GBM) and related prognosticators of outcomes. MATERIALS AND METHODS: From 2011 to 2014, 25 consecutive patients with recurrent (n=17) or secondary (n=7) disease underwent maximal surgery and subsequent HFReRT after meeting the following conditions: 1) confirmation of recurrent or secondary GBM after salvage surgery; 2) Karnofsky performance score (KPS) ≥60; and 3) interval of ≥12 months between initial radiotherapy and HFReRT. HFReRT was delivered using a simultaneous integrated boost technique, with total dose of 45 Gy in 15 fractions to the gross tumor volume (GTV) and 37.5 Gy in 15 fractions to the clinical target volume. RESULTS: During a median follow-up of 13 months, the median progression-free and overall survival (OS) were 13 and 16 months, respectively. A better KPS (p=0.026), no involvement of the eloquent area at recurrence (p=0.030), and a smaller GTV (p=0.005) were associated with better OS. Additionally, OS differed significantly between risk groups stratified by the National Institutes of Health Recurrent GBM Scale (low-risk vs. high-risk, p=0.025). Radiologically suspected radiation necrosis (RN) was observed in 16 patients (64%) at a median of 9 months after HFReRT, and 8 patients developed grade 3 RN requiring hospitalization. CONCLUSION: HFReRT after maximal surgery prolonged survival in selected patients with recurrent GBM, especially those with small-sized recurrences in non-eloquent areas and good performance.

Pituitary apoplexy: pathophysiology, diagnosis and management

Pituitary apoplexy is characterized by sudden increase in pituitary gland volume secondary to ischemia and/or necrosis, usually in a pituitary adenoma. Most cases occur during the 5th decade of life, predominantly in males and in previously unknown clinically non-functioning pituitary adenomas. There are some predisposing factors as arterial hypertension, anticoagulant therapy and major surgery. Clinical picture comprises headache, visual impairment, cranial nerve palsies and hypopituitarism. Most cases improve with both surgical and expectant management and the best approach in the acute phase is still controversial. Surgery, usually by transsphenoidal route, is indicated if consciousness and/or vision are impaired, despite glucocorticoid replacement and electrolyte support. Pituitary function is impaired in most patients before apoplexy and ACTH deficiency is common, which makes glucocorticoid replacement needed in most cases. Pituitary deficiencies, once established, usually do not recover, regardless the treatment. Sellar imaging and endocrinological function must be periodic reevaluated.

Oncological and functional outcomes of salvage renal surgery following failed primary intervention for renal cell carcinoma

Purpose To assess the oncologic and functional outcomes of salvage renal surgery following failed primary intervention for RCC. Materials and Methods We performed a retrospective review of patients who underwent surgery for suspected RCC during 2004-2012. We identified 839 patients, 13 of whom required salvage renal surgery. Demographic data was collected for all patients. Intraoperative and postoperative data included ischemic duration, blood loss and perioperative complications. Preoperative and postoperative assessments included abdominal CT or magnetic resonance imaging, chest CT and routine laboratory work. Estimated glomerular filtration rate (eGFR) was calculated according to the Modification of Diet in Renal Disease equation. Results The majority (85%) of the patients were male, with an average age of 64 years. Ten patients underwent salvage partial nephrectomy while 3 underwent salvage radical nephrectomy. Cryotherapy was the predominant primary failed treatment modality, with 31% of patients undergoing primary open surgery. Pre-operatively, three patients were projected to require permanent post-operative dialysis. In the remaining 10 patients, mean pre- and postoperative serum creatinine and eGFR levels were 1.35 mg/dL and 53.8 mL/min/1.73 m2 compared to 1.43 mg/dL and 46.6 mL/min/1.73 m2, respectively. Mean warm ischemia time in 10 patients was 17.4 min and for all patients, the mean blood loss was 647 mL. The predominant pathological stage was pT1a (8/13; 62%). Negative surgical margins were achieved in all cases. The mean follow-up was 32.9 months (3.5-88 months). Conclusion While salvage renal surgery can be challenging, it is feasible and has adequate surgical, functional and oncological outcomes. .

Long-term oncologic outcomes of postoperative adjuvant versus salvage radiotherapy in prostate cancer: Systemic review and meta-analysis of 5-year and 10-year follow-up data

PURPOSE: To evaluate the oncologic outcomes between adjuvant radiotherapy (ART) and salvage radiotherapy (SRT) in patients with locally advanced prostate cancer or with adverse pathologic factors including positive surgical margin and high Gleason score. MATERIALS AND METHODS: We searched the literature published from January 2000 until December 2014 at MEDLINE, PubMed, Web of Science, Embase, ProQuest, and Cochrane Library. To be specific, included were studies comparing ART and SRT settings if they followed up oncologic outcomes more than 5 years. RESULTS: Overall, 3 retrospective, nonrandomized, observational studies, 1 matched control analysis, and 3 prospective randomized controlled studies met our inclusion criteria including a total of 2,380 patients (1,192 ART vs. 1,188 SRT). Higher favorable results were found in ART than in SRT was seen in the 5-year and 10-year biochemical recurrence (BCR)-free survival (risk ratio [RR], 0.61 and 0.70; 95% confidence interval [CI], 0.54-0.69 and 0.63-0.76). ART had a significantly higher 5-year progression-free survival rate than that in SRT (RR, 0.64; 95% CI, 0.51-0.80), but this was not the same for the 10-year progression-free survival rate (RR, 0.88; 95% CI, 0.72-1.08). There was no significant difference for the 5-year and 10-year overall survival rates between ART and SRT (RR, 0.80 and 0.94; 95% CI, 0.59-1.07 and 0.80-1.11). CONCLUSIONS: ART showed favorable results in BCR-free survival during the 5-year follow-up period. However, the 10-year progression-free survival and overall survival did not show any difference between ART and SRT.

High frequency of dolutegravir resistance in patients failing a raltegravir-containing salvage regimen

OBJECTIVES: Dolutegravir is a second-generation integrase strand transfer inhibitor (InSTI) that has been recently approved by the FDA to treat antiretroviral therapy-naive as well as treatment-experienced HIV-infected individuals, including those already exposed to the first-generation InSTI. Despite having a different mutational profile, some cross-resistance mutations may influence its susceptibility. The aim of this study was to evaluate the impact of a raltegravir-containing salvage regimen on dolutegravir activity. PATIENTS AND METHODS: Blood samples of 92 HIV-infected individuals with virological failure (two or more viral loads >50 copies/mL after 6 months of treatment) using raltegravir with optimized background therapy were sequenced and evaluated according to the Stanford University HIV Drug Resistance Database algorithm. RESULTS: Among the 92 patients analysed, 32 (35%) showed resistance to dolutegravir, in most cases associated with the combination of Q148H/R/K with G140S/A mutations. At genotyping, patients with resistance to dolutegravir had viral load values closer to the highest previously documented viral load. CONCLUSIONS: Changes in viraemia during virological failure may indicate the evolution of raltegravir resistance and may predict the emergence of secondary mutations that are associated with a decrease in dolutegravir susceptibility. Early discontinuation of raltegravir from failing regimens might favour subsequent salvage with dolutegravir, but further studies are necessary to evaluate this issue.

Infliximab versus Cyclosporine Treatment for Severe Corticosteroid-Refractory Ulcerative Colitis: A Korean, Retrospective, Single Center Study

BACKGROUND/AIMS: In patients with corticosteroid-refractory ulcerative colitis (UC), cyclosporine or infliximab may be added to the treatment regimen to induce remission. Here, we aimed to compare the efficacy of cyclosporine and infliximab. METHODS: Between January 1995 and May 2012, the medical records of 43 patients with corticosteroid-refractory UC who received either infliximab or cyclosporine as a rescue therapy at a tertiary care hospital in Korea were reviewed. RESULTS: Among the 43 patients, 10 underwent rescue therapy with cyclosporine and the remaining 33 patients received infliximab. A follow-up of 12 months was completed for all patients. The colectomy rate at 12 months was 30% and 3% in the cyclosporine and the infliximab groups, respectively (p=0.034). However, the Cox proportional hazard model indicated that the treatment of rescue therapy was not an independent associate factor for preventing colectomy (p=0.164). In the subgroup analysis, infliximab with azathioprine was superior to cyclosporine for preventing colectomy (hazard ratio of infliximab with azathioprine compared with cyclosporine only, 0.073; 95% confidence interval, 0.008 to 0.629). CONCLUSIONS: No difference between infliximab and cyclosporine with respect to preventing colectomy was noted. However, infliximab with azathioprine may be more effective than cyclosporine alone for preventing colectomy.

Beyond angiogenesis blockade: targeted therapy for advanced cervical cancer / 부인종양

The global burden of advanced stage cervical cancer remains significant, particular in resource poor countries where effective screening programs are absent. Unfortunately, a proportion of patients will be diagnosed with advanced stage disease, and may suffer from persistent or recurrent disease despite treatment with combination chemotherapy and radiation. Patients with recurrent disease have a poor salvage rate, with an expected 5-year survival of less than 10%. Recently, significant gains have been made in the antiangiogenic arena; nonetheless the need to develop effective alternate targeted strategies is implicit. As such, a review of molecular targeted therapy in the treatment of this disease is warranted. In an era of biologics, combined therapy with cytotoxic drugs and molecular targeted agents, represents an exciting arena yet to be fully explored.

Current Status of Cryotherapy for Prostate and Kidney Cancer

In terms of treating diseases, minimally invasive treatment has become a key element in reducing perioperative complications. Among the various minimally invasive treatments, cryotherapy is often used in urology to treat various types of cancers, especially prostate cancer and renal cancer. In prostate cancer, the increased incidence of low-risk, localized prostate cancer has made minimally invasive treatment modalities an attractive option. Focal cryotherapy for localized unilateral disease offers the added benefit of minimal morbidities. In renal cancer, owing to the increasing utilization of cross-sectional imaging, nearly 70% of newly detected renal masses are stage T1a, making them more susceptible to minimally invasive nephron-sparing therapies including laparoscopic and robotic partial nephrectomy and ablative therapies. This article reviews the various outcomes of cryotherapy compared with other treatments and the possible uses of cryotherapy in surgery.

The survival outcome and patterns of failure in node positive endometrial cancer patients treated with surgery and adjuvant radiotherapy with curative intent / 부인종양

OBJECTIVE: The purpose of this study was to evaluate the patterns of failure, overall survival (OS), disease-free survival (DFS) and factors influencing outcome in endometrial cancer patients who presented with metastatic lymph nodes and were treated with curative intent. METHODS: One hundred and twenty-six patients treated between January 1996 to December 2008 with surgery and adjuvant radiotherapy were identified from our service's prospective database. Radiotherapy consisted of 45 Gy in 1.8 Gy fractions to the whole pelvis. The involved nodal sites were boosted to a total dose of 50.4 to 54 Gy. RESULTS: The 5-year OS rate was 61% and the 5-year DFS rate was 59%. Grade 3 endometrioid, serous, and clear cell histologies and involvement of upper para-aortic nodes had lower OS and DFS. The number of positive nodes did not influence survival. Among the histological groups, serous histology had the worst survival. Among the 54 patients relapsed, only three (6%) failed exclusively in the pelvis and the rest of the 94% failed in extrapelvic nodal or distant sites. Patients with grade 3 endometrioid, serous and clear cell histologies did not influence pelvic failure but had significant extrapelvic failures (p<0.001). CONCLUSION: Majority of node positive endometrial cancer patients fail at extrapelvic sites. The most important factors influencing survival and extrapelvic failure are grade 3 endometrioid, clear cell and serous histologies and involvement of upper para-aortic nodes.

Posaconazole as rescue therapy in African histoplasmosis

Posaconazole Histoplasmosis Salvage therapy African histoplasmosis is a granulomatous mycosis caused by Histoplasma capsulatum var. duboisii. Treatment is usually extrapolated from guidelines for classical histoplasmosis, and includes 2-4 weeks of amphotericin B followed by a step-down maintenance therapy with itraconazole. Pediatric usage of posaconazole, an oral second-generation azole, remains off-label, but recent surveys show that it is safe and well tolerated in children. We report a case of disseminated African histoplasmosis in a 12-year-old boy from Guinea-Bissau. Therapy with amphotericin B and itraconazole led to a progressive clinical deterioration. A dramatic and lasting improvement was observed using posaconazole. He completed 12 months of therapy. No relapse was noted during or 3 months after treatment. We report that posaconazole may be a safe and efficacious drug in the salvage management of disseminated AH, either in patients with disease refractory to conventional anti-fungal therapy, or in patients whose serious adverse effects of first-line drugs preclude its use.

Laringectomia de resgate: utilização do retalho miocutâneo de peitoral maior na prevenção de fístula faringocutânea / The usefulness of a pectoralis major myocutaneous flap in preventing salivary fistulae after salvage total laryngectomy

Laringectomias de resgate estão associadas a altas taxas de complicações pós-operatórias. O uso de retalhos na reconstrução do trânsito faríngeo poderia reduzir a incidência destas complicações. OBJETIVO: Avaliar a utilidade do retalho miocutâneo de músculo peitoral maior na prevenção da fístula salivar no pós-operatório de laringectomia total de resgate. MÉTODO: Estudo retrospectivo, realizado de abril/2006 a maio/2011, com 31 pacientes portadores de CCE de laringe recidivado, tratados previamente com quimiorradioterapia ou radioterapia isolada, submetidos à laringectomia de resgate. Destes 31 pacientes, a reconstrução da faringe foi realizada com utilização do retalho miocutâneo de músculo peitoral maior em 19 (61%) casos, enquanto o fechamento primário ocorreu em 12 pacientes (39%). RESULTADOS: Foi observada taxa de fistula salivar em (16%) dos pacientes em que se utilizou o retalho e 58% nos pacientes submetidos a fechamento primário da faringe (p < 0,02). Não foi observada diferença estatisticamente significativa entre os grupos em relação ao tempo médio de aparecimento de fistula e reintrodução da dieta por via oral, bem como tempo de uso de cateter nasoentérico para alimentação. CONCLUSÃO: O retalho miocutâneo do músculo peitoral maior mostrou-se como opção capaz de reduzir incidência de fistula salivar em laringectomias de resgate.

Salvage laryngectomy in patients treated with organ preservation protocols is associated with high rates of postoperative complications. The use of non-irradiated tissue flaps in pharyngeal reconstruction could reduce the incidence of these complications. OBJECTIVE: This study aims to evaluate the usefulness of the pectoralis major myocutaneous flap in preventing salivary fistulae during the postoperative period of salvage total laryngectomy (TL). MATERIALS AND METHOD: This retrospective study enrolled 31 patients operated between April of 2006 and May of 2011. All patients had advanced cancer at the time of the salvage procedure and had been treated with chemoradiotherapy or radiotherapy alone. Pharyngeal reconstruction was performed using pectoralis major myocutaneous flap in 19 cases (61%); primary wound closure occurred in 12 patients (39%). RESULTS: Salivary fistulae occurred in 16% of the patients who received the flap and in 58% of the patients with primary closure of the pharynx (p < 0.02). No statistically significant differences were noted between the groups with respect to the mean time for fistula formation, reintroduction of an oral diet, or use of a nasoenteric tube for feeding. CONCLUSION: The pectoralis major myocutaneous flap was found to reduce the incidence of salivary fistulae in salvage laryngectomy procedures.

Radiotherapy for early glottic cancer and salvage surgery after recurrence / Radioterapia para câncer glótico inicial e resgate cirúrgico após recorrência

Early glottic cancer can be effectively treated with radiation or surgery, but recurrence is a possibility when using any of the treatment modalities. AIM: To assess the outcome of radiotherapy as initial treatment in the control of squamous cell carcinoma of vocal cord (T1) and the effectiveness of salvage surgery (endoscopic or open) after treatment failure. MATERIALS AND METHODS: A retrospective study was based on the analysis of medical records from 43 patients with T1 squamous cell carcinoma of the glottis, radiotherapy as initial treatment and follow-up period of five years. RESULTS: The rate of recurrence after radiotherapy was 30.2 percent of the cases, mean diagnosis interval was 29.5 months. As an option for salvage treatment, patients underwent open partial laryngectomy or endoscopic surgery with control rates of 77.7 percent and 25 percent respectively. CONCLUSION: Our cases showed high rates of recurrence after radiotherapy and open partial laryngectomy was more effective for the salvage surgery.
