In patients with pPFTs, a considerable proportion experience post-resection CSF diversion within the initial 30 days post-operation, specifically those presenting with preoperative papilledema, PVL, and wound complications. In patients with pPFTs, the formation of post-resection hydrocephalus may be associated with postoperative inflammation, leading to edema and adhesion.
Recent innovations in care notwithstanding, diffuse intrinsic pontine glioma (DIPG) patients unfortunately continue to experience poor outcomes. A retrospective study scrutinizes the care patterns and their repercussions for DIPG patients diagnosed within a five-year period at a single facility.
The demographics, clinical features, care protocols, and outcomes of DIPGs diagnosed between 2015 and 2019 were investigated through a retrospective evaluation. Evaluating steroid usage and treatment responses, the available records and criteria were consulted. Propensity scores were employed to match the re-irradiation cohort, where progression-free survival (PFS) exceeded six months, to a control group of patients receiving supportive care alone, using both PFS and age as continuous variables. Through survival analysis, using the Kaplan-Meier approach and then Cox regression modeling, possible prognostic factors were determined.
A cohort of one hundred and eighty-four patients were recognized, their demographic profiles aligning with those found in Western population-based studies within the literature. find more 424% of the group represented residents from outside the institution's home state. A substantial 752% of patients completed their initial radiotherapy treatment; however, only 5% and 6% experienced worsening clinical symptoms and a continued requirement for steroids one month after the procedure. Multivariate analysis revealed that receiving radiotherapy was associated with improved survival (P < 0.0001), but Lansky performance status below 60 (P = 0.0028) and involvement of cranial nerves IX and X (P = 0.0026) independently predicted worse survival outcomes. In the radiotherapy group, re-irradiation (reRT), and only re-irradiation, showed a statistically significant association with enhanced survival (P = 0.0002).
A significant number of patient families continue to forgo radiotherapy, even though it displays a consistent and substantial association with increased survival and steroid usage. reRT's deployment results in enhanced outcomes for those patients strategically chosen. The involvement of cranial nerves IX and X underscores the need for a more refined and comprehensive care plan.
Radiotherapy, despite its consistent link to improved survival and steroid utilization, remains a treatment option not chosen by many patient families. In select groups, reRT demonstrably contributes to better outcomes. The involvement of cranial nerves IX and X calls for a more sophisticated and refined approach to care.
Prospective investigation of oligo-brain metastases in Indian patients treated solely with stereotactic radiosurgery.
Out of 235 patients screened between January 2017 and May 2022, a total of 138 patients demonstrated conclusive histological and radiological verification. Under a prospective observational study protocol approved by the ethical and scientific review committees, 1 to 5 patients with brain metastasis, exceeding 18 years of age and maintaining a good Karnofsky Performance Status (KPS >70), were enrolled. The study focused on radiosurgery (SRS) treatment using the robotic CyberKnife (CK) system. This study received ethical and scientific committee approval, documented by AIMS IRB 2020-071 and CTRI No REF/2022/01/050237. A thermoplastic mask ensured immobilization, and a contrast-enhanced CT simulation was performed with 0.625 mm slices. The resulting data was merged with T1-weighted and T2-FLAIR MRI images for the purpose of creating precise contours. The radiation dose for the planning target volume (PTV), spanning 20 to 30 Gray, necessitates a 2 to 3 millimeter margin, delivered in 1 to 5 treatment fractions. Toxicity, new brain lesions, free survival, overall survival, and response to CK treatment were all assessed.
Of the 138 patients accrued, 251 lesions were identified (median age 59 years, interquartile range [IQR] 49–67 years, 51% female; headache in 34%, motor deficits in 7%, KPS above 90 in 56%; lung primary tumors in 44%, breast primaries in 30%; oligo-recurrence in 45%; synchronous oligo-metastases in 33%; adenocarcinoma primaries in 83%). The treatment regimen included Stereotactic radiotherapy (SRS) for 107 patients (77%) as the initial treatment. Postoperative SRS was administered to 15 patients (11%), while 12 patients (9%) received whole brain radiotherapy (WBRT) prior to SRS. Finally, 3 (2%) patients received both WBRT and an SRS boost. Solitary brain metastasis (56%) was the most common finding, followed by two to three lesions in 28% of cases, and four to five lesions in 16%. A considerable 39% of the cases presented with frontal site involvement. The median PTV was situated at 155 mL; this represents the middle value, with the interquartile range extending between 81 and 285 mL. The treatment regimen involved a single fraction for 71 patients (52% of the total patients), 14% received three fractions, and 33% received five fractions. Fractionation regimens included 20-2 Gy per fraction, 27 Gy delivered in 3 fractions, and 25 Gy in 5 fractions (mean BED 746 Gy [standard deviation 481; mean monitor units 16608], and average treatment time was 49 minutes [17 to 118 minutes]). The average brain volume of twelve normal Gy subjects was 408 mL (32 percent of the total), falling within a range of 193 to 737 mL. find more After a mean observation period of 15 months (standard deviation of 119 months, maximum follow-up of 56 months), the average actuarial overall survival, following solely SRS treatment, was 237 months (95% confidence interval 20-28 months). Among the patients, 124 (90%) had a follow-up duration exceeding three months, with 108 (78%) having over six months, 65 (47%) exceeding twelve months, and 26 (19%) having more than twenty-four months of follow-up. Of the cases, 72 (522 percent) experienced control of intracranial disease, and 60 (435 percent) experienced control of extracranial disease, respectively. The frequency of in-field recurrence, out-of-field recurrence, and both in- and out-of-field recurrences was 11%, 42%, and 46%, respectively. In the final assessment, 55 patients, or 40%, were still alive; 75 patients, accounting for 54% of the total, passed away due to the disease's progression; and the status of 8 patients (6%) remained unspecified. From a cohort of 75 patients who passed away, 46 (representing 61%) demonstrated progression of the disease outside the cranium, 12 (16%) displayed solely intracranial disease progression, and 8 (11%) died from unrelated causes. Radiological confirmation of radiation necrosis was present in 12 of 117 patients (9%). Similar outcomes emerged from prognostications of Western patients, considering the characteristics of primary tumor type, the count of lesions, and the presence of extracranial disease.
Brain metastasis treatment in the Indian subcontinent, employing solely stereotactic radiosurgery (SRS), yields survival outcomes, recurrence patterns, and toxicities similar to those reported in the Western medical literature. find more Standardization of patient selection, dose scheduling, and treatment planning is crucial for achieving consistent outcomes. WBRT can be safely avoided in Indian patients who have oligo-brain metastases. The applicability of the Western prognostication nomogram extends to the Indian patient population.
In the Indian subcontinent, stereotactic radiosurgery (SRS) proves a viable treatment option for solitary brain metastasis, exhibiting comparable survival, recurrence trends, and toxicity profiles as those published in the Western medical literature. Similar outcomes depend on the standardization of patient selection, dose schedules, and treatment plans. Safety allows the omission of WBRT in Indian patients diagnosed with oligo-brain metastases. The Western prognostication nomogram's applicability holds true for Indian patients.
Fibrin glue, in recent years, has enjoyed growing acceptance as a supplemental therapy for injuries to peripheral nerves. Experimental evidence for fibrin glue's effect on reducing fibrosis and inflammation, major hindrances in tissue repair, is less substantial than the theoretical support.
A comparative examination of nerve repair methods was carried out utilizing two varying rat species, one acting as the donor and the other as the recipient in this trial. Four groups of 40 rats were studied, comparing the use of fibrin glue and fresh or cold-preserved grafts in the immediate post-injury period, through a comprehensive analysis of histological, macroscopic, functional, and electrophysiological data.
Group A allografts, characterized by immediate suturing, displayed suture site granulomas, neuroma development, inflammatory responses, and pronounced epineural inflammation. In contrast, Group B allografts, also with immediate suturing but cold-preserved, demonstrated negligible suture site inflammation and epineural inflammation. Group C allografts, which utilized minimal suturing and glue, demonstrated decreased epineural inflammation, less pronounced suture site granuloma and neuroma development, and this contrast was seen compared to the earlier two groups. Nerve continuity in the subsequent group was less complete when assessed against the two previous groups. In the group treated with fibrin glue (Group D), suture site granulomas and neuromas were nonexistent, with a negligible level of epineural inflammation. However, the majority of rats in this group exhibited either partial or complete absence of nerve continuity, though some showed partial nerve continuity. Regarding functional outcomes, microsuturing, with or without the application of glue, displayed a substantial disparity in achieving superior straight line reconstruction and toe spread as compared to glue alone (p = 0.0042). Group A exhibited the highest electrophysiological nerve conduction velocity (NCV) compared to Group D at the 12-week mark. A marked difference in CMAP and NCV values is apparent in the microsuturing group compared to the control group.
