Robotic Versus Laparoscopic Gastrectomy for Gastric Cancer: The Largest Systematic Reviews of 68,755 Patients and Meta-analysis.

This meta-analysis aimed to compare the efficacy of robotic gastrectomy (RG) and laparoscopic gastrectomy (LG) in treating gastric cancer (GC). A comprehensive literature search across PubMed, MEDLINE, and Web of Science identified 86 eligible studies, including 68,755 patients (20,894 in the RG group and 47,861 in the LG group). The analysis revealed that RG was associated with superior outcomes in several areas: more lymph nodes were harvested, intraoperative blood loss was reduced, postoperative hospital stays were shorter, and the time to first flatus and oral intake was shortened (all p<0.001). Additionally, RG resulted in lower incidences of conversion to open surgery (OR=0.62, p=0.004), reoperation (OR=0.68, p=0.010), overall postoperative complications (OR=0.82, p<0.001), severe complications (OR=0.65, p<0.001), and pancreatic complications (OR=0.60, p=0.004). However, RG had longer operative times and higher costs (both p<0.001). No significant differences were found between RG and LG in terms of resection margin distance, mortality, anastomotic leakage, or recurrence rates. RG is a safe and effective surgical option for patients of GC, but further improvements in operative duration and costs are needed.

Efficacy and safety of reoperation for residual or recurrent hemifacial spasm after microvascular decompression: a systematic review and meta-analysis.

The efficacy and safety of revision microscopic microvascular decompression (microscopic MVD) for treating residual or recurrent hemifacial spasm (HFS) remain uncertain. We conducted a systematic review and meta-analysis to evaluate the benefits and risks associated with this reoperation, focusing primarily on spasm relief, facial palsy, and hearing impairment. This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. We performed a comprehensive search of PubMed, Embase, Web of Science, and the Cochrane Library for eligible articles from their inception through June 2024. A total of 17 studies involving 719 patients were included in this meta-analysis. Among these patients, 668 experienced overall symptom relief following reoperation, resulting in a relief rate of 94% (95% CI: 92-96%). Complete relief was achieved in 603 patients, corresponding to a rate of 87% (95% CI: 80-93%). Transient facial palsy developed in 4% (95% CI: 1-8%) of patients, while persistent facial palsy was observed in 5% (95% CI: 2-8%) of patients following reoperation. Transient hearing impairment occurred in 1% (95% CI: 0-3%) of patients, while persistent hearing impairment was reported in 4% (95% CI: 1-7%) of patients. Patients with recurrent HFS have significantly lower overall and complete relief rates after reoperation compared to those with residual HFS and are at higher risk of long-term hearing loss. Our study suggests that reoperation for residual or recurrent HFS after microscopic MVD could be considered a safe and effective treatment option. Early reoperation may be indicated in specific cases, and the timing should be tailored to each patient's specific circumstances to optimize outcomes.

Second-generation MOSES 2.0 versus MOSES 1.0 pulse-modulation technologies for holmium laser enucleation of the prostate (HoLEP).

To report our initial experience with enhanced MOSES 2.0 technology in patients who underwent holmium laser enucleation of the prostate (HoLEP) for the treatment of benign prostatic hyperplasia (BPH), in comparison to those who underwent HoLEP with MOSES 1.0 technology at our institution. We retrospectively reviewed data of patients who underwent HoLEP using MOSES 1.0 or MOSES 2.0 pulse-modulation technology from December 2020 to September 2023. Preoperative and intraoperative parameters, postoperative outcomes, as well as perioperative complications were collected and analyzed. A total of 196 patients were included in the study. Among them, 146 patients underwent MOSES 1.0 HoLEP, while 50 had MOSES 2.0 HoLEP. No statistically significant differences in preoperative characteristics were observed between the two groups. The median prostate volume for the MOSES 1.0 and MOSES 2.0 HoLEP groups was 109cc and 117.5cc, respectively. Patients in the MOSES 2.0 group had a shorter median enucleation time (52.5 vs. 42.5min, p < 0.001) and hemostasis time (8 vs. 6min, p = 0.002), along with lower laser energy usage (101 vs. 86.4kJ, p = 0.012), when compared to those in the MOSES 1.0 cohort. Postoperative outcomes, including IPSS, QoL, Qmax, and PVR, were comparable between the two groups at 1, 3, and 6 months postoperative. The incidence of hospital readmission (p = 0.42), as well as one-month postoperative urge urinary incontinence (p = 0.2) and stress urinary incontinence (p = 0.13) were also comparable between the cohorts. HoLEP with second-generation MOSES 2.0 technology is a safe and effective treatment option for BPH. It offers notable improvements, including reduced enucleation and hemostasis times, while using less energy when compared to MOSES 1.0.

Evaluating the Effectiveness of Probiotic Supplementation in Combination With Doxycycline for the Treatment of Moderate Acne: A Randomized Double-Blind Controlled Clinical Trial.

Acne is a chronic inflammatory skin disease that negatively affects patients' quality of life. Increasing antibiotic resistance is making acne less responsive to treatment. Probiotics are live microorganisms that can provide health benefits by fighting pathogens and maintaining intestinal homeostasis and skin microbiome balance. This study investigates the effects of probiotics in the treatment of acne vulgaris. In this randomized controlled clinical trial, 80 patients with moderate acne were divided into two groups of 40. All patients received the same topical treatment, which consisted of a daily antibacterial face wash and Adapalene gel every other night. The control group received one capsule of doxycycline (100 mg) daily, whereas the intervention group received one probiotic capsule daily in addition to doxycycline. Patients underwent photography of facial acne lesions, and treatment response was assessed using the global acne grading system (GAGS) and acne grading method at baseline, as well as during follow-up visits at 1, 2, and 3 months. The global acne grading system indicated that both groups showed improvement. However, analyses revealed that outcomes were significantly better in the doxycycline plus probiotics group for the forehead (p = 0.018), chin (p = 0.021), and nose (p = 0.021). No significant differences were observed for the left and right cheeks, back, and chest areas, with the mean GAGS score reduction between the two groups differing by only 2%. Treatment with probiotics significantly reduced the severity of lesions compared to the control group (p < 0.001). The acne grading method also indicated that the intervention group had a significantly better treatment response than the control group (p < 0.001). Furthermore, treatment with probiotics did not result in any side effects. Probiotics can serve as an effective and safe treatment option, enhancing the outcomes of routine acne treatments, particularly for patients with acne on the forehead, chin, and nose.

Evaluation of a New Technique of Gingival Smile Reduction after Hyaluronic Acid Infiltration: A Cohort Study Focusing on Gingival Exposure and Patient-Oriented Outcomes.

A gummy smile is the visualization of more than 3 mm of gingiva above the maxillary incisors. This study aimed to evaluate the long-term effects on aesthetics and patient satisfaction of a new hyaluronic acid infiltration technique in reducing the gummy smile. Fifty patients with gummy smiles were treated using hyaluronic acid infiltration points by applying 0.1 mL per injection at specific points. Post-treatment evaluations were performed one week, one month, three months, six months, and 12 months later. A questionnaire assessed patient satisfaction, willingness to recommend the treatment, and side effects (pain and bruising during and after treatment). An average reduction of 2.5 mm in gingival exposure during smiling was observed. After one week, the reduction was constant. At six months, 40% of the original gingival exposure was recovered, and recovery was complete at 12 months. Patient satisfaction was 82.1%, and 100% of patients would recommend the treatment. Bruising, swelling, and pain decreased to 0% from the first month. In conclusion, this technique is a safe and effective option to improve the smile's appearance with minimal complications.

Cationic amphiphilic molecules as novel sclerosants for venous malformation treatment: A study on tranexamic acid-derived low-molecular-weight gels

Venous malformation (VM) is a prevalent congenital vascular anomaly characterized by abnormal blood vessel growth, leading to disfigurement and dysfunction. Sclerotherapy, a minimally invasive approach, has become a primary therapeutic modality for VM, but its efficacy is hampered by the rapid dilution and potential adverse effects. In this study, we introduced a series of cationic amphiphilic molecules, fatty alcohol esters (TA6, TA8, and TA9) of tranexamic acid (TA), which self-assembled into low-molecular-weight gels (LMWGs) in water. The TA9, in particular, is released slowly when hydrogel is injected into the vein locally. Then, it damages the venous wall by destroying cell membranes and precipitating proteins, causing inflammation and thrombosis, thickening of the venous wall, effectively inducing irreversible vein fibrosis. Additionally, TA9 can be rapidly degraded into TA in plasma to reduce toxicity caused by diffusion. Overall, this study suggests that the cationic amphiphilic molecule TA9 is a promising sclerosant for VM treatment, offering a novel, effective, and safe therapeutic option with potential for clinical translation.

Adult Simultaneous Cochlear Implantation: Local Anesthesia.

Purpose: Cochlear implant (CI) surgery is conventionally done under general anesthesia (GA). However, many patients are unable to undergo GA due to various reasons, raising the need for an alternative safe option. CI under local anesthesia is feasible and safely done in patients who can't tolerate GA. This approach allows for device fitting immediately after surgery. This study aims to evaluate simultaneous bilateral cochlear implant (BiCI) surgery performed under local anesthesia with sedation in adults. To our knowledge, this is the largest cohort of patients who underwent this approach. Methods: This is a retrospective chart review in a tertiary center. We included all adult patients who underwent simultaneous BiCI under local anesthesia with sedation from 2018 to 2024. The feasibility of BiCI under local anesthesia with sedation was assessed through clinical, surgical, audiological, and patient questionnaire data. Results: Six patients underwent simultaneous BiCI with local anesthetic and sedation. Mean age was 41.7 ± 16.0, comprising 66.7% male and 33.3% female. No intraoperative problems were encountered. All woke up from sedation without any agitation or difficulties. Their recovery was uneventful. No dizziness, nausea, or vomiting were reported. The device was activated immediately postoperatively. Pure tone audiometry, speech reception threshold, and word recognition score were significantly improved. Positive experiences were reported in all patients. Conclusion: Bilateral simultaneous cochlear implantation under local anesthesia in adults is achievable, through a multidisciplinary approach. This approach is a potential alternative option for some patients and could optimize their hearing rehabilitation.

Methylene blue therapy in addition to standard treatment for acute-phase septic shock: a pilot randomized controlled trial.

Methylene blue (MB) has been used to increase blood pressure in patients with septic shock by acting on guanylate cyclase and nitric oxide synthase. To determine whether the administration of MB to patients in the initial phase of septic shock leads to a reduction in the use of vasopressors compared to the Control group. This was a 1:1 randomized clinical trial of two groups (MB and Control). Forty-two patients were included in the present study; 23 patients were allocated to the Control group, and 19 were randomized to the MB group. Both groups had access to standard treatment, consisting of fluid replacement, vasopressors, and antibiotic therapy. Patients received a loading dose of MB (3 mg/kg) and maintenance (0.5 mg/kg/h) for 48 h. Vasopressor doses, laboratory test results, inflammatory and anti-inflammatory cytokine levels, and hemodynamic monitoring were recorded before the infusion of MB (T1) and after 20 min (T2), 2 h (T3), 24 h (T4), 48 h after the infusion started (T5) and 24 h after weaning (T6). MB therapy was started together with the indication of vasopressin (VAS) as a second vasopressor. The MB group showed an immediate reduction in NOR dosage, an earlier reduction in VAS dosage, and higher IL-10 levels compared to the Control group. Early administration of MB in combination with standard treatment for septic shock might be reduce vasopressors dose. Continuous infusion of MB for 48 h was considered safe and there was no adverse events. These results highlight the potential of MB as a safe adjuvant therapeutic option in the treatment of septic shock. https://clinicaltrials.gov/, identifier RBR-96584w4.

Medication of the cervical spinal nerves for the treatment of equine cervical radiculopathy

SummaryBackgroundSeveral perineural injection techniques have been described to medicate the cervical spinal nerves of horses with suspected radiculopathy due to lesions at the intervertebral foramen (IVF). The technique and outcome have never been described in live, standing horses with suspected clinical disease.ObjectivesTo assess the safety and efficacy of medication of the ventral rami of the cervical spinal nerves (VRCSNs) for the treatment of cervical radiculopathy in horses.Study designCase series.MethodsHorses that underwent ultrasound‐guided perineural injection of the VRCSNs following radiographic and/or computed tomography (CT) evaluation of the cervical spine were included. Perineural injection with corticosteroids was performed using a standardised technique under ultrasound guidance as previously described. Outcome data were collected by clinical record review and unstructured follow‐up telephone conversations.ResultsForty‐seven injections of the VRCSNs were performed in 12 horses with only two self‐limiting adverse reactions noted. All horses that underwent CT examination had at least one site of IVF narrowing with the foramina at the C6/C7 articulation most frequently affected. Nine horses improved following medication of the VRCSNs with eight returning to their previous levels of exercise. All seven horses that underwent CT of the cervical spine had an initial improvement in clinical signs. Six horses were in full work and still performing at their intended level of exercise at a median of 21.5 months post injection.Main limitationsLack of definitive diagnosis of spinal nerve compression without histopathology of the spinal nerves which is not possible in the live horse.ConclusionsMedication of the VRCSNs is a safe treatment option which may provide benefit to horses with suspected spinal nerve compression but should be reserved for horses that have undergone a detailed clinical examination and CT evaluation of the cervical spine.

Outcomes of HeartMate 3 in pediatric patients with end-stage heart failure: a single-center preliminary experience from Turkey.

We aim to evaluate our initial experience with the HeartMate 3 (HM3) device (Abbott, USA) for palliating pediatric patients with end-stage heart failure (ESHF). We conducted a retrospective review of clinical data from pediatric patients (aged 7-18 years) who underwent HM3 implantation for ESHF at our institution between 2022 and 2024. Patient demographics and follow-up data were comprehensively analyzed. We identified 11 patients (45% males) with a median age of 14 years (IQR 11-17), a median weight of 47 kg (IQR 28-50), a median height of 159 cm (IQR 135-165), and a median body surface area of 1.36 m2 (IQR 1.07-1.53) at the time of the intervention. All patients were diagnosed with dilated cardiomyopathy and categorized with PEDIMACS profiles ranging from one to three. The median ICU stay was 14 days (IQR 6-32), with 11 patients receiving inotropic support for a median of four postoperative days (IQR 3-8). The median follow-up period was 150 days (IQR 90-210). Early complications included two cases of pleural effusion, 1 case of cardiac tamponade, 3 cases of polyuria, and one instance of positive blood cultures. One patient, who was non-compliant with warfarin therapy, developed a thrombus in the right atrium that was resolved with a revision of anticoagulant therapy, and did not experience pump thrombosis. During follow-up, one patient died after 28 days from sepsis, one underwent heart transplantation after 10 days, and nine patients remained alive on the device. Notably, there were no reported cases of pump thrombosis, ischemia, or stroke post- implantation. The HM3 device appears to be a safe and effective palliative option for pediatric patients with ESHF.

Enhancing Stability and Investigating Target Attainment of Benzylpenicillin in Outpatient Parenteral Antimicrobial Therapy: Insights from In Vitro and In Vivo Evaluations.

Background/Objective: Narrow-spectrum beta-lactam antibiotics such as benzylpenicillin and flucloxacillin are increasingly used in outpatient parenteral antimicrobial therapy (OPAT) programs to mitigate the adverse effects associated with broad-spectrum antibiotics. These beta-lactams require continuous administration via portable infusion devices during OPAT. However, the use of benzylpenicillin in OPAT requires special consideration because of its limited stability at elevated temperatures. Methods: We tested the benzylpenicillin stability, pH, and degradation of products in elastomeric pumps at different concentrations in saline and in buffered solution containing sodium citrate during a prolonged storage and at high temperatures (seven days at 2-8 °C followed by 24 h at 37 °C). Additionally, drug concentrations during intermittent bolus infusion and during OPAT were determined in five patients. The concentrations and degradation products of benzylpenicillin were measured using liquid chromatography mass spectrometry (LC-MS/MS). Results: Unbuffered benzylpenicillin solutions that were already degraded during refrigerator storage and analyte concentration were not measurable after 8 days. The stability of the buffered solutions was acceptable at all three of the tested concentrations (97.6 ± 1.3%, 96.3 ± 0.8%, and 94.9 ± 1.1% for 10 Mio IU, 20 Mio IU, and 40 Mio IU of benzylpenicillin). The stability was influenced by benzylpenicillin concentration, and several breakdown products were identified. Benzylpenicillin concentrations were measured in five patients during OPAT and ranged from 7.2 to 60 mg/L. Conclusions: Benzylpenicillin buffered with sodium citrate is a safe and convenient option for use in continuous infusions during OPAT and should be favored over broad-spectrum antibiotics. Therapeutic drug monitoring data indicate sufficient to high plasma levels when patients received benzylpenicillin as continuous infusions.

Real-World Clinical Effectiveness of Liraglutide for Weight Management in Türkiye: Insights from the LIRA-TR Study

Introduction: Obesity is a complicated chronic disease associated with a series of other conditions. A weight loss of 5–10% has been shown to reduce obesity-related complications and improve quality of life. The efficacy and safety of liraglutide for reducing body weight have been demonstrated in clinical trials. This study evaluated the weight loss efficacy and adverse effects of liraglutide in those with obesity in the Turkish population. Methods: This is a retrospective cohort study; the patients that were included had a body mass index (BMI) of 27 or greater with additional comorbidities or a BMI of 30 or greater, and the patients were prescribed liraglutide for obesity treatment from the tertiary private clinic between January 2022 and January 2024. Their metabolic and anthropometric parameters were recorded at the initial appointment, and their body weight and adverse effects were followed up on during therapy. Results: For the 568 patients, of whom 487 (85.6%) were female, the mean values for age, weight, and BMI were 42.37 ± 10.50, 98.09 ± 17.48 kg, and 35.77 ± 5.45 kg/m2, respectively. Reductions in body weight at the 4th, 8th, 12th, and 24th weeks were 6.45 ± 2.32 kg, 10.66 ± 3.41 kg, 15.38 ± 8.30 kg, and 19 ± 9.06 kg, respectively; reductions in BMI at the 4th, 8th, 12th, and 24th weeks were 2.36 ± 1.00, 3.88 ± 1.25, 5.36 ± 1.76, and 7.09 ± 2.93, respectively; and the percentages of overall body weight loss at the 4th, 8th, 12th, and 24th weeks were 6.62 ± 2.1%, 10.75 ± 2.71%, 14.97 ± 6.8%, and 18.55 ± 4.63%, respectively (all p values &lt; 0.0001). The percentage of patients who lost more than 5% and more than 10% of their initial weight was 100% at the 24th week. The most common side effect was nausea; no pancreatitis was observed. Conclusions: The results of our study indicate that liraglutide is an efficacious and safe treatment option for obesity in the Turkish population, in accordance with the findings from previous research.

Safety of 3-month flushing interval for prevention of occlusion in totally implantable venous access ports: An analysis focused on intraluminal clots.

This study aimed to assess the safety and feasibility of a 3-month flushing interval for totally implantable venous access ports (TIVAPs), particularly regarding intraluminal clot formation. Between May 2017 and September 2018, we established a single-center cohort of 151 patients who were referred for TIVAP removal and categorized them into three flushing-interval groups: A (⩽1 month), B (1-2 months), and C (2-3 months). Odds ratios (OR) with 95% confidence intervals (CI) were computed using logistic regression to determine the risk of intraluminal clot occurrence. To compare clot lengths among the groups, we employed linear regression. Restricted cubic splines were used to model the flushing interval as a continuous variable. Compared to Group A, Groups B and C had adjusted ORs of 0.82 (0.35-1.92) and 0.78 (0.29-2.11) for intraluminal clot risk. Occlusion was rare (1/151; 0.7%) and successfully treated with mechanical recanalization. Adjusted differences in clot length compared to Group A were 0.01 (-0.85 to 0.87) for Group B and -0.23 (-1.21 to 0.76) for Group C. Spline regression analysis showed no significant association between the flushing interval and clot length (p for trend = 0.84). The incidence and burden of intraluminal clots did not increase significantly within the first 3 months. Occlusion was rare, even in the presence of clots, and was successfully treated. Therefore, a 3-month flushing interval appears to be a safe and practical option, aligning with the common recommendation for surveillance intervals in patients with cancer.

Combined fractional CO2 laser with dimethyl sulfoxide (DMSO) 50% versus fractional CO2 Laser alone in the treatment of macular amyloidosis: clinical and histopathological assessment.

Macular amyloidosis (MA) could be of cosmetic concern with a significant psychological impact for patients, and its treatment is challenging. To compare the efficacy and safety of combined fractional CO2 laser with dimethyl sulfoxide (DMSO) 50% versus fractional CO2 laser alone in the treatment of macular amyloidosis. Twenty patients with macular amyloidosis were treated with monthly session of fractional CO2 laser only in one side of the lesion (area A), and fractional laser followed by application of DMSO 50% solution in the other side of the lesion (area B). All patients were evaluated clinically, by dermoscope and histopathology before and 3months after the end of 4 treatment sessions. Both treatments showed significant decrease of pigmentation after treatment (p < 0.001). There was non-significant decrease in rippling on both sides (p = 0.06). The median itching score dropped significantly after treatment from 9 to 3.5 in area A (laser only) and to 2 in area B (laser and DMSO), with non-significant difference between both areas (P = 0.244). Dermoscopic features after treatment showed fading and decreasing in multiple features in both areas A and B, with non-significant difference between the 2 areas. Histopathologically, there was significant reduction in the amyloid deposition after treatment in both areas A and B without significant difference between both areas. both fractional CO2 laser combined with topical DMSO 50% and fractional CO2 laser alone are safe and effective treatment options for MA with significant clinical improvement.

Platelet-rich plasma for treatment of female stress urinary incontinence.

Stress urinary incontinence (SUI) poses a significant burden on affected individuals, impairing their quality of life and causing embarrassment due to involuntary urine leakage during activities such as sneezing or coughing. While conservative and surgical treatments exist, a subset of patients experiences persistent symptoms despite these interventions. This review provides insights into the potential role of platelet-rich plasma (PRP) as a therapeutic adjunct for patients with SUI that does not respond to conventional non-surgical or surgical treatments. We conducted a literature review of studies in English to evaluate PRP efficacy in managing SUI. The studies conducted on PRP therapy suggest that it is an effective and safe treatment option for SUI in women. PRP injections, when used alone or in combination with other therapies, have shown significant improvements in SUI symptoms. Moreover, these studies indicate that PRP injections offer a less invasive and low-risk alternative to surgical procedures for managing SUI, which could lead to shorter recovery times. The efficacy of PRP therapy is evidenced by significant reductions in SUI symptoms, as well as improvements in bladder function variables, without significant adverse effects reported. However, further research is necessary to establish the long-term effectiveness and safety of PRP therapy for managing SUI in diverse patient populations. Additionally, ongoing evaluations of PRP therapy in combination with other interventions will be essential for optimizing treatment outcomes and broadening the potential applications of PRP in the management of SUI.

Minimally invasive vs open vs hybrid esophagectomy for esophageal cancer: a systematic review and network meta-analysis.

Robot-assisted minimally invasive esophagectomy (RAMIE) for esophageal carcinoma has emerged as the contemporary alternative to conventional laparoscopic minimally invasive (LMIE), hybrid (HE) and open (OE) surgical approaches. No single study has compared all four approaches with a view to postoperative outcomes. A systematic search of electronic databases was undertaken. A network meta-analysis was performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-network meta-analysis guidelines. Statistical analysis was performed using R and Shiny. Seven randomised controlled trials (RCTs) with 1063 patients were included. Overall, 32.9% of patients underwent OE (350/1063), 11.0% underwent HE (117/1063), 34.0% of patients underwent LMIE (361/1063), and 22.1% of patients underwent RAMIE (235/1063). OE had the lowest anastomotic leak rate 7.7% (27/350), while LMIE had the lowest pulmonary 10.8% (39/361), cardiac 0.56% (1/177) complications, re-intervention rates 5.08% (12/236), 90-day mortality 1.05% (2/191), and shortest length of hospital stay (mean 11.25days). RAMIE displayed the lowest 30-day mortality rate at 0.80% (2/250). There was a significant increase in pulmonary complications for those undergoing OE (OR 3.63 [95% confidence interval: 1.4-9.77]) when compared to RAMIE. LMIE is a safe and feasible option for esophagectomy when compared to OE and HE. The upcoming RCTs will provide further data to make a more robust interrogation of the surgical outcomes following RAMIE compared to conventional open surgery to determine equipoise or superiority of each approach as the era of minimally invasive esophagectomy continues to evolve (International Prospective Register of Systematic Reviews Registration: CRD42023438790).

Salvage reirradiation for recurrent glioblastoma: a retrospective case series analysis.

To assess the clinical outcome of patients with recurrent glioblastoma treated with salvage reirradiation. Between 2005 and 2022, data from adult patients with glioblastoma treated with surgery and radio-chemotherapy Stupp regimen who developed a local in-field relapse and received stereotactic radiotherapy (SRT) were retrospectively reviewed. The study population included 44 patients with recurrent glioblastoma (median of 9.5 months after the first radiotherapy). Reirradiation alone was given to 47.7% of patients. The median maximum diameter of the recurrence was 13.5 mm. The most common SRT regimen (52.3%) was 35 Gy in 10 fractions. Acute toxicity was mild, with transient worsening of previous neurological symptoms in only 15% of patients. After a median follow-up of 15 months, 40% presented radiological response, but a remarkable number of early distant progressions were recorded (32.5%). The median time to progression was 4.8 months, being the dose, the scheme, the size of the recurrence or the strategy (exclusive RT vs. combined) unrelated factors. The median overall survival (OS) was 14.9 months. Karnofsky index < 70 and the size of the recurrence (maximum diameter < 25 mm) were significant factors associated with OS. Radiological changes after reirradiation were commonly seen (> 50% of patients) hindering the response assessment. Reirradiation is a feasible and safe therapeutic option to treat localized glioblastoma recurrences, able to control the disease for a few months in selected patients, especially those with good functional status and small lesions. Hypofractionated schemes provided a suitable toxicity profile. Radiological changes were common.

Initial Patient Characteristics of TSOG 102: A Multicenter Prospective Registry of Active Surveillance in Patients with Multiple Ground Glass Opacities

ObjectivePresentation with multiple ground glass opacities (GGOs) is an increasingly common occurrence, and the optimal management of these lesions is unclear. Active surveillance has been increasingly adopted as a management strategy for other low-grade malignancies. We hypothesized that active surveillance could be a feasible and safe option for patients with multiple GGOs. MethodsPatients with ≥2 GGOs (ground glass predominant, <50% solid, ≤3 cm) were enrolled in a multi-institutional registry and prospectively followed up on active surveillance with computed tomography scans every 6 to 12 months. Each GGO was catalogued and measured individually at each follow-up visit. ResultsTarget accrual was met, with 337 patients from 23 institutions. The mean age was 70 years (interquartile range, 65-77 years), and 74% were women. Most were former (70%) or current (9%) smokers, with a mean exposure of 30 pack-years (interquartile range [IQR], 15-44 pack-years). Half of the patients (51%) had a previous lung cancer, and the majority (86%) were already under surveillance at the time of study entry. The median number of GGOs per patient was 3 (IQR, 2-5), with a total of 1467 GGOs under surveillance. The median GGO size was 0.9 cm (IQR, 0.7-1.3 cm). Most GGOs were 0.5 to 1 cm in size. ConclusionsActive surveillance, rather than immediate intervention, was an acceptable option to patients, and accrual to this registry trial was feasible. Safety endpoints and long-term outcomes will be assessed in the planned 5-year follow-up in accordance with the protocol.
