Fewer systematic prostate core biopsies in clinical stage T1c prostate cancer leads to biochemical recurrence after brachytherapy as monotherapy. Prostate 2024; 84:502-510. [PMID: 38173289 DOI: 10.1002/pros.24668] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 11/22/2023] [Accepted: 12/18/2023] [Indexed: 01/05/2024]
Abstract
BACKGROUND After brachytherapy, fewer prostate biopsy cores at diagnosis can underestimate the pathological characteristics of prostate cancer (PCa) with lower concordance, resulting in improper treatment, particularly in patients with low-risk nonpalpable cT1c PCa. The aim of this study was to assess the relationship between the number of biopsy cores at diagnosis and long-term clinical outcomes after brachytherapy for cT1c PCa. METHODS We reviewed 516 patients with localized cT1c PCa with Gleason scores of 3 + 3 = 6 or 3 + 4 = 7 who underwent brachytherapy as monotherapy without hormonal therapy between January 2005 and September 2014 at our institution. Clinical staging was based on the American Joint Committee on Cancer manual for staging. Thus, the cT1c category is based solely on digital rectal examination. The primary outcome was biochemical recurrence (BCR). Based on the optimized cutoff value for biopsy core number obtained from receiver operating characteristic analysis, patients were divided into the biopsy cores ≤8 (N = 123) and ≥9 (N = 393) groups. The BCR-free survival rate was compared between the groups. Prognostic factors for BCR were evaluated, including age, initial prostate-specific antigen (PSA) level, Gleason score, positive core rate, PSA density, prostate magnetic resonance imaging findings, and biopsy core number. RESULTS The median patient age was 66.0 years (interquartile range [IQR]: 61.0-71.0 years), and the median follow-up time was 11.1 years (IQR: 9.5-13.3 years). The median number of core biopsies was 12 (IQR: 9-12). The area under the curve was 0.637 (95% confidence interval [CI]: 0.53-0.75), and the optimal biopsy core cutoff value for BCR prediction was 8.5 (sensitivity = 43.5%, specificity = 77.1%). Although fewer patients had Gleason scores of 3 + 4 = 7 (19/123 [15%] vs. 125/393 [32%], p < 0.02) in the biopsy cores ≤8 group, the 10-year BCR-free survival rate was significantly lower in the biopsy cores ≤8 group than in the biopsy cores ≥9 group (93.8% vs. 96.3%, p < 0.05). Multivariate analysis revealed that a lower biopsy core number (hazard ratio: 0.828, 95% CI: 0.71-0.97, p < 0.03) and a Gleason score of 3 + 4 = 7 (hazard ratio: 3.26, 95% CI: 1.37-7.73, p < 0.01) significantly predicted BCR. CONCLUSIONS A low number of prostate core biopsies results in worse BCR-free survival after brachytherapy as monotherapy in patients with cT1c PCa.

Abstract
Hereditary leiomyomatosis and renal cell carcinoma caused by loss-of-function germline variants of the FH gene can develop into aggressive renal cell carcinoma (RCC). We report the case of a 27-year-old man who died of RCC. Genetic testing revealed a novel pathogenic variant of FH, NM_000143.3:c.1013_1014del (p.Ile338Serfs*3), that was also identified in healthy siblings. Identification of genetic causes in the proband helped us to provide relatives with precise genetic counseling and appropriate surveillance programs.

Abstract
BACKGROUND Keloid lesions are characterized by mesenchymal cell proliferation and excessive extracellular matrix deposition. Previous microarray analyses have been performed to investigate the mechanism of keloid development. However, the molecular pathology that contributes to keloid development remains obscure. AIM To explore the underlying essential molecules of keloids using microarrays. METHODS We performed microarray analyses of keloid and nonlesional skin tissues both in vivo and in vitro. Gene expression levels were compared between tissues and cells. Quantitative reverse transcription (qRT)-PCR and immunohistochemical staining were used to determine the expression levels of molecules of interest in keloid tissues. RESULTS Several common molecules were upregulated in both keloid tissues and keloid-lesional fibroblasts. PTPRD and NTM were upregulated both in vivo and in vitro. The genes MDFI and ITGA4 were located at the centre of the gene coexpression network analysis using keloid tissues. qRT-PCR revealed significant expression levels of PTPRD and MDFI in keloid tissues. Immunopathological staining revealed that MDFI-positive cells, which have fibroblast characteristics, were located in the keloid-associated lymphoid tissue (KALT) portion of the keloid tissue. CONCLUSION Our gene expression profiles of keloids could distinguish the difference between lesional tissue and cultured lesional fibroblasts, and MDFI was found to be commonly expressed in both tissues and cells. Thus, MDFI-positive cells, which were located in the KALT, may play an important role in keloid pathogenesis and thus might be useful for in vitro keloid studies.

Abstract
Abstract
Background
Door-to-balloon time in patients with ST-elevation myocardial infarction is reported to be an independent predictor of the prognostic implication. However, the effect of door-to-deployment time (DTDT) of venoarterial extracorporeal membrane oxygenation (VA-ECMO) on patients with out-of-hospital cardiac arrest (OHCA) is unclear.
Purpose
This single-center, retrospective, observational study aimed to evaluate the effect of DTDT of VA-ECMO for mortality or neurological outcome of extracorporeal cardiopulmonary resuscitation (ECPR) in patients with cardiogenic OHCA.
Method
This single-center, retrospective, observational study was conducted from January 2008 to April 2019. The primary endpoint was 1-month overall survival measured after ECMO initiation. Moreover, the secondary endpoint was 1-month survival with favorable neurological functions defined as having a cerebral performance category score of 1 or 2.
Result
A total of 3082 patients with OHCA were brought to our institution and 84 received ECPR. Of these, 51 consecutive adult patients with cardiogenic OHCA without sustained return of spontaneous circulation during transport were included in this analysis. Approximately 18 patients (18/51, 35.3%) survived after 1 month and were discharged. Among the survivors, 15 (15/18, 83.3%) were discharged with a favorable neurological outcome. The baseline characteristics between the survivors and non-survivors were not significantly different, except for the initial shockable rhythm [18/18 (100%) versus 28/33 (84.9%), P=0.03]. There were no significant differences between the median time from collapse to hospital arrival [31.0 min (IQR 25.0–31.0) versus 29.0 min (IQR 25.0–39.5), P=0.53] and from call to hospital arrival [28.0 min (IQR 22.0–32.5) versus 27.0 min (IQR 23.3–34.5), P=0.56]. The median DTDT of VA-ECMO was significantly shorter in survivors [13.0 min (IQR 11.5–18.3) versus 21.0 minutes (IQR 15.5–32.0), P=0.01]. The Kaplan–Meier survival analysis showed that the group with a DTDT ≤20 min had a significantly higher 1-month overall survival rate (P<0.01) and survival rate with a favorable neurological outcome (P=0.01) than that with a DTDT >20 minutes. Using the Cox proportional hazards analysis, DTDT ≤20 minutes and bystander-witnessed significantly affected the overall survival rate at 1 month [adjusted hazard ratio (HR), 0.44; 95% confidence interval (CI), 0.20–0.95; P=0.03 and adjusted HR, 0.31; 95% CI, 0.13–0.74; P<0.01, respectively]. Regarding survival rate with a favorable neurological outcome, the result was relatively similar [adjusted HR, 0.46; 95% CI, 0.22–0.96; P=0.04 and adjusted HR, 0.37; 95% CI, 0.16–0.85; P=0.02, respectively].
Conclusion
This study revealed that the DTDT of VA-ECMO is significantly associated with the 1-month mortality and neurological prognosis of patients with cardiogenic OHCA. However, further studies will be required to confirm these findings.

Effect of adding androgen deprivation therapy to permanent iodine-125 implantation with or without external beam radiation therapy on the outcomes in patients with intermediate-risk prostate cancer: A propensity score-matched analysis. Brachytherapy 2020; 20:10-18. [PMID: 33069598 DOI: 10.1016/j.brachy.2020.08.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 08/27/2020] [Accepted: 08/28/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE The purpose of the study was to evaluate the effect of adding androgen deprivation therapy (ADT) to brachytherapy with or without external beam radiation therapy on oncological outcomes in prostate cancer. METHODS AND MATERIALS Overall, 1,171 patients with intermediate-risk prostate cancer treated with brachytherapy with or without external beam radiation therapy with or without ADT between 2003 and 2013 were identified. Propensity score matching was used to counter biases between the ADT and non-ADT groups. The biochemical failure-free rate (bFFR), local recurrence-free rate, and overall survival rate were evaluated using Kaplan-Meier curves, and predictors were identified using Cox proportional hazards regression models. RESULTS After propensity score matching, 405 patients were included in each group. The median followup duration was 9.1 years; the median ADT duration was 6 months. In the ADT versus non-ADT groups, the 9-year bFFR, local recurrence-free rate, and overall survival rate were 93.4% versus 87.8% (p = 0.016), 96.9% versus 98.1% (p = 0.481), and 88.1% versus 90.4% (p = 0.969), respectively. On multivariate analyses, Gleason score (hazard ratio [HR]: 2.52, 95% confidence interval [CI]: 1.58-4.03) and ADT use (HR: 0.55, 95% CI: 0.34-0.89) were associated with biochemical failure. Supplemental external beam radiation therapy use (HR: 0.38, 95% CI: 0.16-0.91) was associated with lower local recurrence rates. Age (HR: 1.12, 95% CI: 1.08-1.16) and comorbidities (HR: 1.56, 95% CI: 1.04-2.34) were associated with all-cause mortality. CONCLUSIONS A risk-benefit assessment between bFFR improvement and the potential side effects of adding ADT to brachytherapy-based radiotherapy is warranted before incorporating ADT as routine practice.

Abstract
Ulinastatin vaginal suppositories, used to prevent threatened premature delivery, are frequently used in hospitals. However, there is no established method for quantifying ulinastatin contained in suppositories. Therefore, we investigated a simple and efficient method for quantifying ulinastatin contained in suppositories. Our analytical method involved removal of the base; optimising the enzyme inhibition reaction time and enzyme reaction time; and measuring the absorbance. The modified method was reproducible, operation time was significantly shortened, and cost was reduced to approximately 1/17 of that of the previously reported method. This simple and rapid quantitative method could contribute to the improvement of quality control of ulinastatin vaginal suppositories as an extemporaneous hospital preparation.

Abstract
BACKGROUND Physiological changes after laparoscopic ventral rectopexy (LVR) in patients with rectoanal intussusception (RAI) remain unclear. This study was undertaken to evaluate physiological and morphological changes after LVR for RAI, and to study clinical outcomes following LVR with special reference to fecal incontinence (FI). METHODS The study was conducted on patients who had LVR for RAI between February 2012 and December 2016 at our institution Patients with RAI and FI were included in the study. Patients with RAI and obstructed defecation and those with RAI and neurologic FI were not included. The patients had anorectal manometry preoperatively, and 3, 6, and 12 months postoperatively. Defecography was performed before and 6 months after the procedure. FI was evaluated using the Fecal Incontinence Severity Index (FISI). RESULTS There were 34 patients (median age 77 years (range 60-93) years). Thirty-two patients (94%) were female and the median number of vaginal deliveries was 2 (range 0-5). Neither maximum resting pressure nor maximum squeeze pressure increased postoperatively. There was an overall increase in both defecatory desire volume (median preoperative 75 ml vs. 90 ml at 12 months; p = 0.002) and maximum tolerated volume (median preoperative 145 ml vs.175 ml at 12 months; p = 0.002). Postoperatively, RAI was eliminated in all patients but one, although 13 had residual rectorectal intussusception found at defecography. There was an overall reduction in both rectocele size (median preop 29 mm vs. postop 10 mm; p = 0.008) and pelvic floor descent (median preop 26 mm vs. postop 20 mm; p = 0.005). Twelve months after surgery, a reduction of at least 50% was observed in the FISI score for 31 incontinent patients (91%). CONCLUSIONS LVR for RAI produced adequate improvement of FI, and successful anatomical correction of RAI was confirmed by postoperative proctography. Postoperative increase in the rectal volume may have a positive effect on continence.

Temporal and spatial variations of 134Cs and 137Cs levels in the Sea of Japan and Pacific coastal region: Implications for dispersion of FDNPP-derived radiocesium. JOURNAL OF ENVIRONMENTAL RADIOACTIVITY 2018; 182:142-150.

Abstract
To investigate the dispersion of Fukushima Dai-ichi Nuclear Power Plant (FDNPP)-derived radiocesium in the Sea of Japan and western Pacific coastal region and determine the sources of radiocesium in these areas, we examined the temporal and spatial variations of 134Cs and 137Cs concentrations (activities) during 2011-2016 in seawaters around the western Japanese Archipelago, particularly in the Sea of Japan. In May 2013, the surface concentration of 134Cs was ∼0.5 mBq/L (decay-corrected to March 11, 2011), and that of 137Cs exceeded the pre-accident level in this study area, where the effects of radiocesium depositions just after the FDNPP accident disappeared in surface waters in October 2011. Subsequently, radiocesium concentrations gradually increased during 2013-2016 (∼0.5-1 mBq/L for 134Cs), exhibiting approximately homogeneous distributions in each year. The temporal and spatial variations of 134Cs and 137Cs concentrations indicated that FDNPP-derived radiocesium around the western Japanese Archipelago, including the Sea of Japan, has been supported by the Kuroshio Current and its branch, Tsushima Warm Current, during 2013-2016. However, in the Sea of Japan, the penetration of 134Cs was limited to depths of less than ∼200 m during three years following the re-delivery of FDNPP-derived radiocesium.

Abstract
Salvage radical prostatectomy is one of treatments after radiation therapy to patients with prostate cancer. To date, no case of the salvage robotic assisted radical prostatectomy (RARP) following heavy ion radiotherapy (HIRT) has been published. We report on a 70-year-old man with a history of HIRT for prostate cancer in 2011. For 3 years after. HIRT, his serum PSA levels were permissible range. However, his PSA levels were increased. We had diagnosis localized prostate cancer after HIRT. We had carried out salvage RARP. Until 10 months after salvage RARP, his PSA level was not detectable.

Predictive factors for urinary toxicity after iodine-125 prostate brachytherapy with or without supplemental external beam radiotherapy. Brachytherapy 2016; 15:288-295. [PMID: 26924022 DOI: 10.1016/j.brachy.2015.12.011] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2015] [Revised: 12/20/2015] [Accepted: 12/21/2015] [Indexed: 11/28/2022]
Abstract
PURPOSE We examined the factors associated with urinary toxicities because of brachytherapy with iodine-125 with or without supplemental external beam radiotherapy (EBRT) for prostate cancer. METHODS AND MATERIALS We investigated 1313 patients with localized prostate cancer treated with iodine-125 brachytherapy with or without supplemental EBRT between 2003 and 2009. The International Prostate Symptom Score (IPSS) and Common Terminology Criteria for Adverse Events data were prospectively determined. Patients, treatment, and implant factors were investigated for their association with urinary toxicity or symptoms. RESULTS IPSS resolution was not associated with biologically effective dose (BED). Baseline IPSS, total needles, and the minimal dose received by 30% of the urethra had the greatest effect according to multivariate analysis (MVA). Urinary symptom flare was associated with baseline IPSS, age, BED, and EBRT on MVA. Urinary symptom flare and urinary Grade 2 or higher (G2+) toxicity occurred in 51%, 58%, and 67% (p = 0.025) and 16%, 22%, and 20% (p = 0.497) of the <180, 180-220, and >220 Gy BED groups, respectively. Urinary G2+ toxicity was associated with baseline IPSS, neoadjuvant androgen deprivation therapy (NADT), and seed density on MVA. When we divided patients into four groups according to prostate volume (<30 cc or ≥30 cc) and NADT use, urinary G2+ toxicity was most commonly observed in those patients with larger prostates who received NADT, and least in the patients with smaller prostates and no NADT. CONCLUSIONS NADT was associated with urinary G2+ toxicity. Higher dose and supplemental EBRT did not appear to increase moderate to severe urinary toxicities or time to IPSS resolution; however, it influenced urinary symptom flare.

Abstract
Bone is the third most common site of metastasis from upper tract urothelial carcinoma after radical nephroureterectomy. Although bone biopsy is the gold standard for the diagnosis of bone metastases, they can usually be diagnosed on the basis of imaging tests. We describe a case of upper tract urothelial carcinoma after radical nephroureterectomy presenting with a Schmorl node in the third lumbar vertebra, mimicking lytic bone metastasis. Differentiation of bone metastases from Schmorl nodes is essential for the appropriate management of patients with malignancy.

A dose-response analysis of biochemical control outcomes after (125)I monotherapy for patients with favorable-risk prostate cancer. Int J Radiat Oncol Biol Phys 2015; 90:1069-75.

Abstract
PURPOSE To define the optimal dose for (125)I prostate implants by correlating postimplantation dosimetry findings with biochemical failure and toxicity. METHODS AND MATERIALS Between 2003 and 2009, 683 patients with prostate cancer were treated with (125)I prostate brachytherapy without supplemental external beam radiation therapy and were followed up for a median time of 80 months. Implant dose was defined as the D90 (the minimal dose received by 90% of the prostate) on postoperative day 1 and 1 month after implantation. Therefore, 2 dosimetric variables (day 1 D90 and day 30 D90) were analyzed for each patient. We investigated the dose effects on biochemical control and toxicity. RESULTS The 7-year biochemical failure-free survival (BFFS) rate for the group overall was 96.4% according to the Phoenix definition. A multivariate analysis found day 1 D90 and day 30 D90 to be the most significant factors affecting BFFS. The cutoff points for day 1 D90 and day 30 D90, calculated from ROC curves, were 163 Gy and 175 Gy, respectively. By use of univariate analysis, various dosimetric cutoff points for day 30 D90 were tested. We found that day 30 D90 cutoff points from 130 to 180 Gy appeared to be good for the entire cohort. Greater D90s were associated with an increase in late genitourinary or gastrointestinal toxicity ≥ grade 2, but the increase was not statistically significant. CONCLUSIONS Improvements in BFFS rates were seen with increasing D90 levels. Day 30 D90 doses of 130 to 180 Gy were found to serve as cutoff levels. For low-risk and low-tier intermediate-risk prostate cancer patients, high prostate D90s, even with doses exceeding 180 Gy, achieve better treatment results and are feasible.
