A nomogram for predicting risk factors of testicular salvage after testicular torsion in children.

OBJECTIVES: This study aimed to establish a nomogram for predicting the probability of testicular salvage after testicular torsion in children. METHODS: We retrospectively collected data of children with testicular torsion who were treated at Shenzhen Children's Hospital between September 2005 and August 2022. Of the training cohort, 113 patients who underwent orchiectomy and five with testicular atrophy after orchiopexy were included in the failed testicular salvage group. Additionally, 37 patients who underwent orchiopexy without postoperative testicular atrophy were included in the successful testicular salvage group. The predictive factors affecting testicular salvage were determined using univariate and multivariate logistic regression analyses; a nomogram was constructed. The nomogram was verified using data from the validation group. RESULTS: Using multivariate logistic regression analysis, the independent risk factors of testicular salvage after testicular torsion were symptom duration (p = 0.034), intratesticular blood flow (p = 0.003), spermatic cord torsion degree (p = 0.037), and monocyte count (odds ratio: 0.012, p = 0.036). A nomogram was established based on these four risk factors. In the training cohort, the area under the receiver operating characteristic curve was 0.969. The area under the receiver operating characteristic curve of the verification cohort was 0.965, indicating good discrimination ability of the nomogram. Increased symptom duration without intratesticular blood flow increased the monocyte count and spermatic cord torsion degree and decreased the success rate of testicular salvage. CONCLUSION: This prediction model could obtain the corresponding probability of testicular salvage according to the clinical characteristics of different patients with testicular torsion, providing reference for clinicians and parents.

Outcomes of Supracricoid Partial Laryngectomy Performed in the United States: A Systematic Review.

OBJECTIVE: The primary objective of this study was to evaluate oncologic outcomes of all published cases of supracricoid partial laryngectomy (SCPL) performed in the United States. The secondary objective was to assess the functional outcomes associated with this procedure. REVIEW METHODS: A systematic review of PubMed, SCOPUS, and Embase for all English-language studies pertaining to SCPL performed in the United States was conducted until August 2021. Primary outcomes included disease-specific survival (DSS), overall survival, and local recurrence rate. Secondary outcomes included larynx preservation rate, gastrostromy tube dependency, days to gastrostomy tube removal, decannulation rate, and days to decannulation. RESULTS: A total of six studies were included in the analysis. A total of 113 patients (58.5%) underwent SCPL surgery as a primary treatment method whereas 80 patients (41.5%) underwent SCPL as salvage surgery. The 5-year DSS rates were 87.8% and 100% for primary and salvage procedures, respectively. Approximately 10.3% of patients undergoing a salvage SCPL procedure experienced a local recurrence whereas only 1.85% of primary SCPL procedures resulted in local recurrence. The rates of decannulation following primary and salvage SCPL were 92.7% and 88.1%, respectively. With regard to swallowing, primary and salvage SCPL procedures demonstrated comparably low postoperative gastrostomy tube dependency rates of 3.66% and 4.76%, respectively. CONCLUSIONS: SCPL performed in the United States is an effective surgical technique that produces excellent outcomes in qualifying patients, thus validating its viability as an organ-preserving surgical alternative.

Near Disappearance of Splenorrhaphy as an Operative Strategy for Splenic Preservation After Trauma.

BACKGROUND: Splenorrhaphy was once used to achieve splenic preservation in up to 40% of splenic injuries. With increasing use of nonoperative management and angioembolization, operative therapy is less common and splenic injuries treated operatively are usually high grade. Patients are often unstable, making splenic salvage unwise. Modern surgeons may no longer possess the knowledge to perform splenorrhaphy. METHODS: The records of adult trauma patients with splenic injuries from September 2014 to November 2018 at an urban level I trauma center were reviewed retrospectively. Data including American Association for the Surgery of Trauma splenic organ injury scale, type of intervention, splenorrhaphy technique, and need for delayed splenectomy were collected. This contemporary cohort (CC) was compared to a historical cohort (HC) of splenic injuries at a single center from 1980 to 1989 (Ann Surg 1990; 211: 369). RESULTS: From 2014 to 2018, 717 adult patients had splenic injuries. Initial management included 157 (21.9%) emergent splenectomy, 158 (22.0%) angiogram ± embolization, 371 (51.7%) observation, and only 10 (1.4%) splenorrhaphy. The HC included a total of 553 splenic injuries, of which 313 (56.6%) underwent splenectomy, while splenorrhaphy was performed in 240 (43.4%). Those who underwent splenorrhaphy in each cohort (CC vs HC) were compared. CONCLUSION: The success rate of splenorrhaphy has not changed. However, splenorrhaphy now involves only electrocautery with topical hemostatic agents and is used primarily in low-grade injuries. Suture repair and partial splenectomy seem to be "lost arts" in modern trauma care.

Concordance of biopsy and pathologic ISUP grading in salvage radical prostatectomy patients for recurrent prostate cancer.

PURPOSE: To investigate the concordance of biopsy and pathologic International Society of Urological Pathology (ISUP) grading in salvage radical prostatectomy (SRP) patients for recurrent prostate cancer. METHODS: Within a high-volume center database, we identified patients who underwent SRP for recurrent prostate cancer (PCa) between 2004 and 2020. Upgrading, downgrading, concordance, and any discordance between posttreatment biopsy ISUP and ISUP at SRP were tested. Logistic regression models were used to predict ISUP upgrading and ISUP discordance. Models were adjusted for prostatic specific antigen before SRP, age at surgery, initial prostatic specific antigen (PSA), type of primary treatment, time from primary PCa diagnosis to SRP, number of positive cores at biopsy, and original Gleason score. RESULTS: Overall, 184 patients with available biopsy and pathologic ISUP grading were identified. Of those, 17.4% (n = 32), 40.8% (n = 75), 19.6% (n = 36), and 22.2% (n = 41) harbored biopsy ISUP 1, ISUP 2, ISUP 3, and ISUP 4-5 grading, respectively. Pathologic ISUP 1, ISUP 2, ISUP 3, and ISUP 4-5 grading was recorded in 6.0% (n = 11), 40.8% (n = 75), 32.1% (n = 59), and 21.2% (n = 39), respectively. Median PSA before SRP was 5.5 ng/ml (interquartile range [IQR]: 3.1-8.1 ng/ml), median age at SRP was 65.1 years (IQR:60.7-69.4 years) and median time from original PCa diagnosis to SRP was 47 months (IQR: 27.3-85.2 months). Concordance of biopsy and pathologic ISUP was identified in 45.1% (n = 83). Conversely, any ISUP discordance, upgrading and downgrading of at least one ISUP group was identified in 54.9% (n = 101), 35.3% (n = 65), and 19.6% (n = 36). In logistic models, none of the preoperative characteristics was associated with upgrading or ISUP discordance (all p > 0.1). CONCLUSION: Discordance between biopsy and pathologic ISUP grading is common at SRP. However, in 45% of SRP cases biopsy ISUP is capable to predict pathologic ISUP. Further studies are necessary to identify characteristics for ISUP upgrading at SRP.

Surgical Interventions During End-of-Life Hospitalizations in Children's Hospitals.

OBJECTIVES: To characterize patterns of surgery among pediatric patients during terminal hospitalizations in children's hospitals. METHODS: We reviewed patients ≤20 years of age who died among 4 424 886 hospitalizations from January 2013-December 2019 within 49 US children's hospitals in the Pediatric Health Information System database. Surgical procedures, identified by International Classification of Diseases procedure codes, were classified by type and purpose. Descriptive statistics characterized procedures, and hypothesis testing determined if undergoing surgery varied by patient age, race and ethnicity, or the presence of chronic complex conditions (CCCs). RESULTS: Among 33 693 terminal hospitalizations, the majority (n = 30 440, 90.3%) of children were admitted for nontraumatic causes. Of these children, 15 142 (49.7%) underwent surgery during the hospitalization, with the percentage declining over time (P < .001). When surgical procedures were classified according to likely purpose, the most common were to insert or address hardware or catheters (31%), explore or aid in diagnosis (14%), attempt to rescue patient from mortality (13%), or obtain a biopsy (13%). Specific CCC types were associated with undergoing surgery. Surgery during terminal hospitalization was less likely among Hispanic children (47.8%; P < .001), increasingly less likely as patient age increased, and more so for Black, Asian American, and Hispanic patients compared with white patients (P < .001). CONCLUSIONS: Nearly half of children undergo surgery during their terminal hospitalization, and accordingly, pediatric surgical care is an important aspect of end-of-life care in hospital settings. Differences observed across race and ethnicity categories of patients may reflect different preferences for and access to nonhospital-based palliative, hospice, and end-of-life care.

Central Venous Catheter Salvage in Ambulatory Central Line-Associated Bloodstream Infections.

BACKGROUND: Guidelines for treatment of central line-associated bloodstream infection (CLABSI) recommend removing central venous catheters (CVCs) in many cases. Clinicians must balance these recommendations with the difficulty of obtaining alternate access and subjecting patients to additional procedures. In this study, we evaluated CVC salvage in pediatric patients with ambulatory CLABSI and associated risk factors for treatment failure. METHODS: This study was a secondary analysis of 466 ambulatory CLABSIs in patients <22 years old who presented to 5 pediatric medical centers from 2010 to 2015. We defined attempted CVC salvage as a CVC left in place ≥3 days after a positive blood culture result. Salvage failure was removal of the CVC ≥3 days after CLABSI. Successful salvage was treatment of CLABSI without removal of the CVC. Bivariate and multivariable logistic regression analyses were used to test associations between risk factors and attempted and successful salvage. RESULTS: A total of 460 ambulatory CLABSIs were included in our analysis. CVC salvage was attempted in 379 (82.3%) cases. Underlying diagnosis, CVC type, number of lumens, and absence of candidemia were associated with attempted salvage. Salvage was successful in 287 (75.7%) attempted cases. Underlying diagnosis, CVC type, number of lumens, and absence of candidemia were associated with successful salvage. In patients with malignancy, neutropenia within 30 days before CLABSI was significantly associated with both attempted salvage and successful salvage. CONCLUSIONS: CVC salvage was often attempted and was frequently successful in ambulatory pediatric patients presenting with CLABSI.

Pattern of care in radiotherapy at a University Hospital in Spain: the RENORT project

Purpose RENORT is a novel data mining application developed to extract relevant clinical data from oncology information systems (OIS; ARIA and Mosaiq) used in radiation oncology (RO). Methods/patients We used RENORT to extract demographic and clinical data from the OIS of all patients treated at the RO Department at the General Hospital of Valencia during the year 2019. Results A total of 1158 treatments were performed. The female/male ratio was 39.3%/60.7%, with a mean age of 66 years. The mean waiting time between the treatment decision/proposal to the first visit was 10.1 days. Mean duration of the treatment preparation process was 21 days. Most patients (90.4%) completed treatment within the prescribed time ± 7 days. The most common sites/treatment types were: metastatic/palliative treatments (n = 300; 25.9%), breast (209; 18.0%), genitourinary (195; 16.8%), digestive (116; 10.0%), thoracic (104; 9.0%), head and neck (62; 5.4%), and skin cancer (51; 4.4%). The distribution according to treatment intent was as follows: palliative (n = 266; 23.0%), adjuvant curative (335; 28.9%), radical without adjuvant treatment (229; 19.8%), radical with concomitant treatment (188; 16.2%), curative neoadjuvant (70; 6.0%), salvage radiotherapy (61; 5.3%); and reirradiation (9; 0.8%). The most common treatment techniques were IMRT/VMAT with IGRT (n = 468; 40.4%), 3D-CRT with IGRT (421; 36.4%), SBRT (127; 11.0%), 2DRT (57; 4.9%), and SFRT (56; 4.8%). A mean of 15.9 fractions were administered per treatment. Hypofractionated schemes were used in 100% of radical intent breast and prostate cancer treatments. Conclusions The RENORT application facilitates data retrieval from oncology information systems to allow for a comprehensive determination of the real role of radiotherapy in the treatment of cancer patients. This application is valuable to identify patterns of care and to assess treatment efficacy (AU)

Twenty-year experience with salvage total laryngectomy: lessons learned.

OBJECTIVE: The purpose of this study was to evaluate the outcome of salvage total laryngectomy and identify areas for further improvement. METHOD: A retrospective analysis of all patients who underwent salvage total laryngectomy between January 1999 and December 2018 was performed. RESULTS: Thirty-one patients were identified. The most common primary tumour site was the glottis (83.8 per cent). Early stage (T1-T2) disease was identified in 83.9 per cent of cases. Overall survival at 2 and 5 years post-salvage total laryngectomy was 71 per cent and 45 per cent, respectively. Disease-free survival at 2 and 5 years post-salvage total laryngectomy was 65 per cent and 42 per cent, respectively. The rate of post-salvage total laryngectomy pharyngocutaneous fistula was 29 per cent. CONCLUSION: More than half of patients will not survive beyond five years after salvage total laryngectomy. Regional recurrence was the most common form of failure and death. From this study, elective lateral and central neck dissection is advocated in patients with early laryngeal cancer who present with an advanced recurrence.

Salvage Following Transoral Laser Microsurgery for Early Glottic Cancer in National Veteran Database.

OBJECTIVES: Transoral laser microsurgery (TLM) is commonly utilized for early glottic cancer and offers favorable oncologic and functional outcomes. However, the survival implications of salvage therapy for recurrent or persistent disease have not been definitively characterized. STUDY DESIGN: Retrospective, national database cohort study. METHODS: Data were extracted from Veterans Health Affairs (VHA) Informatics and Computing Infrastructure (VINCI) concerning the TLM-based management of T1-T2 glottic squamous cell carcinoma patients between 2000 and 2017. Patients were characterized as either requiring TLM-only, or in cases of persistent or recurrent local disease, TLM plus change in treatment modality (radiotherapy, chemoradiotherapy, or open surgery). Predictors of overall survival (OS), cancer-specific survival (CSS), and salvage-free survival were evaluated via Cox and Fine-Gray models. RESULTS: About 553 patients (70.9% T1a, 13.4% T1b, 15.7% T2) were included, with a median follow-up time of 74.5 months. The need for non-TLM salvage increased along with more advanced disease (11.7% T1a, 29.7% T1b, 32.2% T2). Compared to patients with T1a disease, those with T1b and T2 tumors initially treated with TLM had a significantly higher probability of receiving non-TLM salvage (T1b: HR 2.70, 95% CI: 1.61-4.54; T2: HR 3.02, 95% CI: 1.88-4.84). In a multivariable model, receipt of non-TLM salvage was not a significant predictor of either OS (HR = 0.91, 95% CI: 0.62-1.33, P = .624) or CSS (HR 1.21 95% CI 0.51-2.86, P = .667). CONCLUSION: The majority of patients with early glottic cancer that are managed with TLM do not require additional salvage therapy. When non-TLM salvage was required, there was no decrement in OS or CSS. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:2766-2772, 2021.

5-Year Outcomes Following Focal Laser Ablation of Prostate Cancer.

OBJECTIVE: To characterize the oncologic outcomes 5 years following focal laser ablation (FLA) of localized prostate cancer. METHODS: 36 men underwent in-bore FLA of prostate cancer at our institution between 2013 and 2015. Follow up included digital rectal examination and PSA testing, multiparametric MRI, and MR-guided biopsies. The primary outcome of interest was failure-free survival (FFS), defined as avoidance of salvage whole gland treatment, systemic therapy, metastasis, or death from prostate cancer. RESULTS: Of the 36 men enrolled, 6 were ultimately lost to follow-up. Of the remaining 30, 25 (83%) have remained free from failure over a median follow-up of 71 months'. Among these patients, 10 (40%) developed in-field recurrence, with 9 undergoing salvage partial gland ablation with FLA, cryotherapy, or high-intensity focused ultrasound. Five patients underwent salvage whole gland or systemic treatment and were thus considered to have failed treatment. Two patients developed metastatic disease, and after receiving radiation and ADT, both currently have undetectable PSA levels. No patients in the cohort died from prostate cancer. Limitations include a small study cohort and lack of standardized surveillance protocols 2 years after treatment. CONCLUSION: FLA for select cases of prostate cancer provides high rates of FFS, defined as freedom from whole gland or systemic treatment, metastasis, or death from prostate cancer. However, in- or out-of-field recurrence is common and often necessitates salvage ablation.

Comparative Outcomes of Salvage Retzius-Sparing versus Standard Robotic Prostatectomy: An International, Multi-Surgeon Series.

PURPOSE: Salvage radical prostatectomy is rare due to the risk of postoperative complications. We compare salvage Retzius-sparing robotic assisted radical prostatectomy (SRS-RARP) with salvage standard robotic assisted radical prostatectomy (SS-RARP). MATERIALS AND METHODS: A total of 72 patients across 9 centers were identified (40 SRS-RARP vs 32 SS-RARP). Demographics, perioperative data, and pathological and functional outcomes were compared using Student's t-test and ANOVA. Cox proportional hazard models and Kaplan-Meier curves were constructed to assess risk of incontinence and time to continence. Linear regression models were constructed to investigate postoperative pad use and console time. RESULTS: Median followup was 23 vs 36 months for SRS-RARP vs SS-RARP. Console time and estimated blood loss favored SRS-RARP. There were no differences in complication rates or oncologic outcomes. SRS-RARP had improved continence (78.4% vs 43.8%, p <0.001 for 0-1 pad, 54.1% vs 6.3%, p <0.001 for 0 pad), lower pads per day (0.57 vs 2.03, p <0.001), and earlier return to continence (median 47 vs 180 days, p=0.008). SRS-RARP was associated with decreased incontinence defined as >0-1 pad (HR 0.28, 95% CI 0.10-0.79, p=0.016), although not when defined as >0 pad (HR 0.56, 95% CI 0.31-1.01, p=0.053). On adjusted analysis SRS-RARP was associated with decreased pads per day. Lymph node dissection and primary treatment with stereotactic body radiation therapy were associated with longer console time. CONCLUSIONS: SRS-RARP is a feasible salvage option with significantly improved urinary function outcomes. This may warrant increased utilization of SRS-RARP to manage men who fail nonsurgical primary treatment for prostate cancer.

The role for intra-arterial chemotherapy for refractory retinoblastoma: a systematic review.

BACKGROUND: Intra-arterial chemotherapy is a new retinoblastoma treatment associated with high rates of globe salvage that has been widely adopted for primary treatment of retinoblastoma but is less frequently used as secondary treatment for refractory retinoblastoma. This systematic review aims to summarize the reported outcomes of intra-arterial chemotherapy for refractory retinoblastoma. METHODS: We conducted a systematic review of studies published on PubMed, Medline, and Embase from 2011 to 2021 reporting globe salvage rates following intra-arterial chemotherapy for secondary treatment of refractory retinoblastoma. RESULTS: Our search yielded 316 studies, and 24 met inclusion criteria. The 24 included studies were comprised of 1366 patients and 1757 eyes. Among these, 1184 (67%) eyes received secondary indication treatment, and globe salvage was achieved for 776 of these 1184 eyes (64%). Sixteen studies reported cannulation success rates from 71.8 to 100%. Pooled analysis of subjects revealed 21 patients (2.6%) with metastatic disease and 26 deaths (3%) during study follow-up periods (7-74 months). The most common ocular complications were vitreous hemorrhage (13.2%), loss of eyelashes (12.7%), and periocular edema (10.5%). The most common systemic complications were nausea/vomiting (20.5%), neutropenia (14.1%), fever (8.2%), and bronchospasm (6.2%). CONCLUSIONS: Intra-arterial chemotherapy is associated with high rates of globe salvage and low rates of serious complications in patients with refractory retinoblastoma. Unfortunately, current literature is predominantly comprised of retrospective case studies, and further high-quality evidence is necessary to inform clinical practice.

Retrospective Analysis of Adult Patients With Relapsed/Refractory Acute Myeloid Leukemia Treated with FLAG at a Comprehensive Cancer Center.

BACKGROUND: FLAG ± Ida (fludarabine, cytarabine, granulocyte colony-stimulating factor, and idarubicin), is a salvage chemotherapy regimen for relapsed or refractory (R/R) acute myeloid leukemia (AML), with complete remission (CR) rates historically ranging from 52% to 63%. We review the outcomes for patients with R/R AML treated with FLAG ± Ida at the University of California Davis Comprehensive Cancer Center. PATIENTS AND METHODS: Adult patients (≥ 18 years) with R/R AML who received FLAG or FLAG + Ida from January 1, 2012 to October 31, 2016 were identified via chart review. Outcomes evaluated were CR, CR with incomplete hematologic recovery (CRi), overall response rate, overall survival (OS), relapse-free survival, and adverse events. RESULTS: Forty-two patients were included. The median age was 52 years (range, 23-73 years), and 57% were male. Sixteen (38.1%) patients had relapsed disease, and 26 (61.9%) had refractory disease. Most (n = 35; 83.3%) patients had European LeukemiaNet intermediate-risk AML. Responses were CR in 20 (47.6%) and CRi in 6 (14.3%). The median OS was 10 months (range, 0.8-51 months), and the median relapse-free survival was 12 months (range, 1-51 months) for responders. The median OS for patients who achieved CR was not reached, and the estimated 48-month survival rate was 56%. The median OS after CRi or no response was 3.47 and 2.17 months, respectively. The median OS was not significantly different when censored for stem cell transplant following chemotherapy, nor with use/deferral of idarubicin. The most common adverse effects were pancytopenia and infection. CONCLUSION: Patient outcomes after treatment with FLAG ± Ida for R/R AML remain similar to prior reports, confirming its role as a salvage regimen for these patients.

Pattern of care in radiotherapy at a University Hospital in Spain: the RENORT project.

PURPOSE: RENORT is a novel data mining application developed to extract relevant clinical data from oncology information systems (OIS; ARIA and Mosaiq) used in radiation oncology (RO). METHODS/PATIENTS: We used RENORT to extract demographic and clinical data from the OIS of all patients treated at the RO Department at the General Hospital of Valencia during the year 2019. RESULTS: A total of 1158 treatments were performed. The female/male ratio was 39.3%/60.7%, with a mean age of 66 years. The mean waiting time between the treatment decision/proposal to the first visit was 10.1 days. Mean duration of the treatment preparation process was 21 days. Most patients (90.4%) completed treatment within the prescribed time ± 7 days. The most common sites/treatment types were: metastatic/palliative treatments (n = 300; 25.9%), breast (209; 18.0%), genitourinary (195; 16.8%), digestive (116; 10.0%), thoracic (104; 9.0%), head and neck (62; 5.4%), and skin cancer (51; 4.4%). The distribution according to treatment intent was as follows: palliative (n = 266; 23.0%), adjuvant curative (335; 28.9%), radical without adjuvant treatment (229; 19.8%), radical with concomitant treatment (188; 16.2%), curative neoadjuvant (70; 6.0%), salvage radiotherapy (61; 5.3%); and reirradiation (9; 0.8%). The most common treatment techniques were IMRT/VMAT with IGRT (n = 468; 40.4%), 3D-CRT with IGRT (421; 36.4%), SBRT (127; 11.0%), 2DRT (57; 4.9%), and SFRT (56; 4.8%). A mean of 15.9 fractions were administered per treatment. Hypofractionated schemes were used in 100% of radical intent breast and prostate cancer treatments. CONCLUSIONS: The RENORT application facilitates data retrieval from oncology information systems to allow for a comprehensive determination of the real role of radiotherapy in the treatment of cancer patients. This application is valuable to identify patterns of care and to assess treatment efficacy.

Does Up-front Autologous Stem-Cell Transplantation at First Relapse Improve Outcome in Transplant-Eligible Follicular Lymphoma Patients Whose Disease Relapses Within 24 Months?

BACKGROUND: In Canadian adults, follicular lymphoma (FL) is the most common subtype of non-Hodgkin lymphomas. Approximately 20% of patients with FL experience progression of disease within 2 years of first-line chemoimmunotherapy. Those patients have an expected overall survival of less than 5 years. The optimal second-line treatment for these high-risk patients is unclear. PATIENTS AND METHODS: We analyzed data from the Blood and Bone Marrow Transplantation Center at Ottawa Hospital to determine whether autologous stem-cell transplantation as up-front therapy for first relapse can improve outcomes in this high-risk FL subgroup. We identified 17 patients who underwent up-front autologous stem-cell transplantation between February 2012 and February 2019. RESULTS: The disease of all patients had relapsed within 24 months after receipt of their first rituximab-based chemotherapy. Overall survival at 2 and 5 years was 86.2% (95% confidence interval [CI], 55-96) and 71.8% (95% CI, 31-91), respectively. The progression-free survival at 2 and 5 years was 62.6% (95% CI, 35-81) and 53.6% (95% CI, 25-75), respectively. CONCLUSION: Overall survival is improved when receiving autologous hematopoietic stem-cell transplantation as up-front therapy at first relapse in transplant-eligible FL whose disease relapses within 24 months of first-line therapy. Data from our single center look promising, but the data need to be replicated with a larger sample size.

Oncologic outcome of radical prostatectomy versus radiotherapy as primary treatment for high and very high risk localized prostate cancer.

OBJECTIVE: To compare the oncologic outcomes of radical prostatectomy (RP) versus external beam radiotherapy (EBRT) ± androgen deprivation therapy for primary treatment of high risk localized prostate cancer (CaP). METHODS: We retrospectively reviewed a prospectively-populated database for cases who underwent primary treatment for high risk localized CaP, had more than 2 years follow-up, and were treated since 2006. A total of 335 cases were studied of whom 291 underwent RP and 44 underwent EBRT. Clinical characteristics, biochemical progression-free survival (BPFS), metastasis-free survival (MFS), cancer-specific survival (CSS) and overall survival (OS) were compared. RESULTS: EBRT cases were older (p < .01; mean 71 years vs. 61 years) and had longer PSA doubling time (PSADT) (p = .03; median 4.8 years vs. 3.5 years) than RP. Race, pretreatment PSA and biopsy Gleason score were similar. Median follow-up was 5.1 (range: 2.3-12.8) years for RP versus 3.3 (range: 2-12.4) years for EBRT. Three- and 5-year BPFS were 42% and 36% after RP versus 86% and 75% after EBRT (p < .01). The rate of adjuvant/salvage therapy was 58% after RP versus 20% after EBRT (p < .01). Three- and 5-year MFS were 80% and 77% after RP versus 91% and 91% after EBRT (p = .11). Three-year CSS was 98% in both groups and OS was 97% after RP versus 94% after EBRT (p = .73). CONCLUSIONS: RP had higher rates of biochemical failure and adjuvant or salvage treatment versus EBRT in high risk localized CaP. MFS trended toward benefit after EBRT, but CSS and OS remained high in both groups.

Salvage surgery for patients with residual disease after chemoradiation therapy for locally advanced cervical cancer: A systematic review on indication, complications, and survival.

INTRODUCTION: Standard treatment for locally advanced cervical cancer is chemoradiation therapy. Treatment with chemoradiation therapy harbors a risk of local residual disease, which can be curatively treated with salvage surgery, but the risk of complications following surgical procedures in radiated tissue is not negligible. The presence of residual disease can be radiologically and/or histologically diagnosed. The objective of this study is to describe studies that report on salvage surgery for patients with locally advanced cervical cancer after primary treatment with chemoradiation therapy. Therefore, we assessed the method of determining the presence of residual disease, the risk of complications, and the survival rate after salvage surgery. MATERIAL AND METHODS: PubMed, EMBASE, and the Cochrane database were searched from inception up to 6 March 2020. Titles and abstracts were independently assessed by two researchers. Studies were eligible for inclusion when patients had locally advanced cervical cancer with radiologically suspected or histologically confirmed residual disease after chemoradiation therapy, diagnosed with a CT, MRI, or PET-CT scan, or biopsy. Information on complications after salvage surgery and survival outcomes had to be reported. Methodological quality of the articles was independently assessed by two researchers with the Newcastle-Ottawa scale. RESULTS: Of the 2963 screened articles, six studies were included, representing 220 women. A total of 175 patients were treated with salvage surgery, of whom 27%-100% had residual disease on the surgery specimen. Of the 161 patients treated with salvage surgery based on positive biopsy results, 72%-100% showed residual disease on the surgery specimen. Of the 44 patients treated with salvage surgery based on suspected residual disease on radiology, 27%-48% showed residual disease on the salvage surgery specimen. A total of 105 complications were registered in 175 patients treated with salvage surgery. The overall survival rate after salvage surgery was 69% (mean follow-up period of 24.9 months). CONCLUSIONS: It is necessary to confirm residual disease by biopsy before performing salvage surgery in patients with locally advanced cervical cancer primarily treated with chemoradiation therapy. Salvage surgery only based on radiologically suspected residual disease should be avoided to prevent unnecessary surgery and complications.

Application of a multi-institutional nomogram predicting salvage whole brain radiation-free survival to patients treated with postoperative stereotactic radiotherapy for brain metastases.

PURPOSE: The ultimate goal of stereotactic radiotherapy (SRT) of brain metastases (BM) is to avoid or postpone whole brain radiotherapy (WBRT). A nomogram based on multi-institutional data was developed by Gorovets, et al. to estimate the 6 and 12-months WBRT-free survival (WFS). The aim of the current retrospective study was to validate the nomogram in a cohort of postoperative BM patients treated with adjuvant SRT. MATERIAL AND METHODS: We reviewed the data of 68 patients treated between 2008-2017 with postoperative SRT for BM. The primary endpoint was the WFS. The receiver operating characteristic curve and area under the curve (AUC) were calculated for both 6- and 12-months time points. RESULTS: After a median follow-up of 64 months, the 1-year cumulative incidence of local and distant brain relapse rates were 15% [95% CI=8-26%] and 34% [95% CI=24-48%], respectively. At recurrence, repeated SRT or salvage WBRT were applied in 33% and 57% cases, respectively. The WFS rates at 6 and 12 months were 88% [95% CI=81-97%] and 67% [95% CI=56-81%], respectively. Using the Gorovets nomogram, the 6 months rates were overestimated while they were accurate at 12 months. AUC values were 0.47 and 0.62 for the 6- and 12-months respectively. Overall, Harrell's concordance index was 0.54. CONCLUSION: This nomogram-predicted well the 12 months WFS but its discriminative power was quite low. This underlines the limits of this kind of predictive tool and leads us to consider the use of big data analysis in the future.
