Oral Drug Dosing After Gastric Bypass and Diet-Induced Weight Loss: Simpler Than We Think? Lessons Learned From the COCKTAIL Study.

This article summarizes the lessons learned from the COCKTAIL study: an open, three-armed, single-center study including patients with obesity scheduled for treatment with Roux-en-Y gastric bypass (RYGB) or nonsurgical calorie restriction, and a normal- to overweight control group. The clinical implications of the results from multiple peer-reviewed articles describing the effects of RYGB, severe caloric restriction, weight loss, and type 2 diabetes on the in vivo activity and protein expression of drug-metabolizing enzymes (cytochrome P450 (CYP) 1A2, 2C9, 2C19, and 3A) and transporters (DMETs; organic anion-transporting polypeptide (OATP) 1B1 and P-glycoprotein (P-gp)) are discussed in the perspective of three clinically relevant questions: (1) How should clinicians get the dose right in patients after RYGB? (2) Will drug disposition in patients with obesity be normalized after successful weight loss? (3) Are dose adjustments needed according to obesity and diabetes status? Overall, RYGB seems to have a lower impact on drug disposition than previously assumed, but clinicians should pay close attention to drugs with a narrow therapeutic range or where a high maximum drug concentration may be problematic. Whether obesity-related alterations of DMETs normalize with substantial weight loss depends on the DMET in question. Obesity and diabetes downregulate the in vivo activity of CYP2C19 and CYP3A (only obesity) but whether substrate drugs should be dose adjusted is also dependent on other factors that influence clearance, that is, liver blood flow and protein binding. Finally, we recommend frequent and individualized follow-up due to high inter- and intraindividual variability in these patients, particularly following RYGB.

An update on drug-drug interactions in older adults living with human immunodeficiency virus (HIV).

People with HIV are living longer due to advances in antiretroviral therapy. With improved life expectancy comes an increased lifetime risk of comorbid conditions - such as cardiovascular disease and cancer - and polypharmacy. Older adults, particularly those living with HIV, are more vulnerable to drug interactions and adverse effects, resulting in negative health outcomes. Antiretrovirals are involved in many potential drug interactions with medications used to treat common comorbidities and geriatric conditions in an aging population of people with HIV. We review the mechanisms and management of significant drug-drug interactions involving antiretroviral medications and non-antiretroviral medications commonly used among older people living with HIV. The management of these interactions may require dose adjustments, medication switches to alternatives, enhanced monitoring, and considerations of patient- and disease-specific factors. Clinicians managing comorbid conditions among older people with HIV must be particularly vigilant to side effect profiles, drug-drug interactions, pill burden, and cost when optimizing treatment. To support healthier aging among people living with HIV, there is a growing need for antiretroviral stewardship, multidisciplinary care models, and advances that promote insight into the correlations between an individual, their conditions, and their medications.

Clinical and electroencephalographic correlates of carbamazepine-associated hiccups in epileptic patients

Carbamazepine, a commonly prescribed antiepileptic drug, is known to induce hiccups in a subset of epileptic patients. Though relatively uncommon, this phenomenon this phenomenon can have significant clinical implications. This comprehensive review delves into the clinical and electroencephalographic correlates of carbamazepine-associated hiccups, aiming to enhance understanding and management of this neurological side effect. Our review synthesizes qualitative epidemiological data, revealing that carbamazepine-induced hiccups occur in a subset of patients receiving the medication, with reported incidence rates ranging from 2.5% to 40%. Despite its relatively low prevalence, hiccups pose substantial challenges for patients and healthcare providers. Complications associated with carbamazepine-induced hiccups include disruption of sleep, impaired social functioning, and decreased quality of life, underscoring the clinical significance of this side effect. Effective management strategies can be implemented through a multidisciplinary approach, including collaboration among neurologists, pharmacists, and other healthcare professionals. These may include dose adjustments, medication discontinuation, and adjunctive therapies such as diaphragmatic breathing exercises or acupuncture. Additionally, close monitoring for adverse effects and timely intervention are essential to mitigate the impact of hiccups on patient well-being. Essentially, carbamazepine-induced hiccups represent a clinically relevant phenomenon that warrants attention in the management of epilepsy. By recognizing the clinical manifestations, understanding the underlying pathophysiology, and implementing evidence-based management strategies, healthcare providers can optimize patient care and improve outcomes in this patient population.

Efficacy and safety of anlotinib in patients with desmoid fibromatosis: a retrospective analysis

Efficacy and safety of anlotinib in patients with desmoid fibromatosis: a retrospective analysis

Aficamten for Symptomatic Obstructive Hypertrophic Cardiomyopathy.

One of the major determinants of exercise intolerance and limiting symptoms among patients with obstructive hypertrophic cardiomyopathy (HCM) is an elevated intracardiac pressure resulting from left ventricular outflow tract obstruction. Aficamten is an oral selective cardiac myosin inhibitor that reduces left ventricular outflow tract gradients by mitigating cardiac hypercontractility. In this phase 3, double-blind trial, we randomly assigned adults with symptomatic obstructive HCM to receive aficamten (starting dose, 5 mg; maximum dose, 20 mg) or placebo for 24 weeks, with dose adjustment based on echocardiography results. The primary end point was the change from baseline to week 24 in the peak oxygen uptake as assessed by cardiopulmonary exercise testing. The 10 prespecified secondary end points (tested hierarchically) were change in the Kansas City Cardiomyopathy Questionnaire clinical summary score (KCCQ-CSS), improvement in the New York Heart Association (NYHA) functional class, change in the pressure gradient after the Valsalva maneuver, occurrence of a gradient of less than 30 mm Hg after the Valsalva maneuver, and duration of eligibility for septal reduction therapy (all assessed at week 24); change in the KCCQ-CSS, improvement in the NYHA functional class, change in the pressure gradient after the Valsalva maneuver, and occurrence of a gradient of less than 30 mm Hg after the Valsalva maneuver (all assessed at week 12); and change in the total workload as assessed by cardiopulmonary exercise testing at week 24. A total of 282 patients underwent randomization: 142 to the aficamten group and 140 to the placebo group. The mean age was 59.1 years, 59.2% were men, the baseline mean resting left ventricular outflow tract gradient was 55.1 mm Hg, and the baseline mean left ventricular ejection fraction was 74.8%. At 24 weeks, the mean change in the peak oxygen uptake was 1.8 ml per kilogram per minute (95% confidence interval [CI], 1.2 to 2.3) in the aficamten group and 0.0 ml per kilogram per minute (95% CI, -0.5 to 0.5) in the placebo group (least-squares mean between-group difference, 1.7 ml per kilogram per minute; 95% CI, 1.0 to 2.4; P<0.001). The results for all 10 secondary end points were significantly improved with aficamten as compared with placebo. The incidence of adverse events appeared to be similar in the two groups. Among patients with symptomatic obstructive HCM, treatment with aficamten resulted in a significantly greater improvement in peak oxygen uptake than placebo.

The impact of sugammadex dosing and administration practices on potential cost savings for pharmacy departments.

In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. Neuromuscular blocking agents (NMBAs) are commonly used during surgery, and restoring neuromuscular function at the end of surgery is vital in preventing complications of residual paralysis. Recent guidelines from the American Society of Anesthesiology recommend using sugammadex over neostigmine; however, sugammadex is significantly more expensive than neostigmine and may increase drug expenditure for pharmacy departments. This review summarizes evidence evaluating sugammadex dose adjustments and the potential of these dose adjustments to lead to cost savings for pharmacy departments. We found evidence suggesting that the manufacturer-recommended sugammadex dose may not be needed in many patients and that dosing based on an adjusted body weight or based on depth of neuromuscular blockade may lead to lower sugammadex usage. Combining sugammadex with neostigmine could also decrease the dose of sugammadex required. We have highlighted the importance of objective neuromuscular monitoring to guide sugammadex dosing and evaluation for residual neuromuscular blockade. Cost savings for pharmacy departments may be realized by these alternative dosing strategies and/or vial-splitting practices. Implementing practices related to sugammadex vial splitting and dose adjustment based on body weight and depth of neuromuscular blockade shows potential benefits in terms of sugammadex cost savings.

Effects of PCSK9 on thrombosis and haemostasis in a variety of metabolic states: Lipids and beyond (Review).

Proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitors are widely recognised as being able to induce a potent reduction in low‑density lipoprotein‑cholesterol. An increasing number of studies have suggested that PCSK9 also influences the haemostatic system by altering platelet function and the coagulation cascade. These findings have significant implications for anti‑PCSK9 therapy in patients with specific coagulation conditions, including expanded indications, dose adjustments and drug interactions. The present review summarises the changes in PCSK9 levels in individuals with liver diseases, chronic kidney diseases, diabetes mellitus, cancer and other disease states, and discusses their impact on thrombosis and haemostasis. Furthermore, the structure, effects and regulatory mechanisms of PCSK9 on platelets, coagulation factors, inflammatory cells and endothelial cells during coagulation and haemostasis are described.

Background: Bilastine is a second-generation antihistamine for the symptomatic treatment of allergic rhinoconjunctivitis (ARC) and urticaria in adults, adolescents, and children. The pharmacokinetics and safety of oral bilastine 10 mg/d in children aged 2 to 5 years were evaluated. Methods: This was a multicenter, open-label clinical trial in children aged 2 to 5 years with seasonal or perennial ARC or urticaria treated once daily with bilastine 10 mg orodispersible tablets. The safety evaluation included treatment-emergent adverse events (TEAEs), vital signs, and physical examination. Pharmacokinetic data were pooled with data from a prior pediatric study, and pharmacokinetic modeling was performed to assess consistency. Results: A total of 37 children with ARC (81.1%), urticaria (8.1%), or both (10.8%) were included in the study, with a mean (SD) age of 3.7 (1.2) years. The highest plasma concentrations of bilastine were observed 1 hour after administration (634.91 ng/mL). Eight patients (21.6%) experienced 1 TEAE each, none of which was severe. Body weight and age were not covariates of variation in either systemic clearance or the volume of distribution in children aged 2 to 5 years and did not affect the pharmacokinetic parameters of bilastine. Conclusions: The pharmacokinetics of bilastine was linear and consistent with data from a previous trial, suggesting that a 10-mg dose may be used in children (2 to &lt;12 years). No dose adjustments are deemed necessary. Oral once-daily bilastine 10 mg presented a good safety profile in children aged 2 to 5.

A systematic review and meta-analysis of the morbidity of efficacy endpoints and bleeding events in elderly and young patients treated with the same dose rivaroxaban.

Rivaroxaban is a new direct oral anticoagulant, and the same dose is recommended for older and young patients. However, recent real-world studies show that older patients may need dose adjustment to prevent major bleeding. At present, the evidence for dose adjustment in older patients is extremely limited with only a few reports on older atrial fibrillation patients. The aim of this study was to review the morbidity data of adverse events and bleeding events across all indications for older and young patients treated with the same dose of rivaroxaban to provide some support for dosage adjustment in older patients. The PubMed, EMBASE, ClinicalTrials, Cochrane and Web of Science databases were searched for randomized controlled trials (RCTs) published between January 1, 2005, and October 10, 2023. The primary outcomes were the morbidity of bleeding events and efficacy-related adverse events. Summary estimates were calculated using a random effects model. Eighteen RCTs were included in the qualitative analysis. The overall morbidity of primary efficacy endpoints was higher in older patients compared to the young patients (3.37% vs. 2.60%, χ2 = 5.24, p = 0.022). Similarly, a higher morbidity of bleeding was observed in older patients compared to the young patients (4.42% vs. 6.03%, χ2 = 13.22, p < 0.001). Among all indications, deep vein thrombosis, pulmonary embolism and atrial fibrillation were associated with the highest incidence of bleeding in older patients, suggesting that these patients may be most need dose adjustment. Patients older than 75 years may require extra attention to prevent bleeding. The same dose of rivaroxaban resulted in higher bleeding morbidity and morbidity of efficacy-related adverse events in older patients compared to the young patients. An individualized dose adjustment may be preferred for older patients rather than a fixed dose that fits all.

Effects of low-dose magnesium oxide on elevated serum magnesium levels and improved constipation in hemodialysis patients: a single-center retrospective study

BackgroundThe prevention of hypomagnesemia is critical for improving the life expectancy of patients undergoing hemodialysis (HD). The administration of magnesium oxide (MgO) increases serum Mg concentrations; however, dose adjustments must be done carefully owing to the risk of hypermagnesemia in patients undergoing HD. Additionally, the laxative effects of low-dose MgO on constipation in these patients has not been reported. Therefore, in the present study, we investigated the effects of treatment with low-dose MgO on serum Mg concentration changes and the improvement of defecation in patients undergoing HD.MethodsThe present study was a single-center retrospective observational study of 43 patients undergoing maintenance HD at Shirasagi Hospital. The patients’ clinical characteristics, including serum Mg concentration, were obtained from the hospital’s electronic medical records. In the group who received MgO for constipation, the effectiveness of MgO as a laxative was categorized as effective, ineffective, or unknown on the basis of electronic medical records related to defecation.ResultsOf the 43 patients included in the present study, 23 were prescribed supplemental Mg to prevent hypomagnesemia or maintain mild hypermagnesemia and 19 to prevent constipation. All patients received diasylate with an Mg concentration of 1.0 mEq/L. Additionally, 37 patients (86%) were treated with 330 mg/day MgO. The serum Mg concentrations before and 1, 2, and 3 months after the start of MgO were 2.3 ± 0.2, 2.8 ± 0.4, 2.8 ± 0.5, and 2.8 ± 0.4 mg/dL, respectively (P < 0.001). Multiple linear regression analysis showed that dry weight was independently associated with changes in serum Mg concentration from before to 1 month after MgO administration (regression coefficient = −0.027; P = 0.020). Of the 19 patients evaluated for constipation, 8 (42%) had documented effective bowel movements after the initiation of MgO, 6 had no effect, and 5 were unknown; however, 1 patient in the ineffective group and 2 in the effective group used other laxatives prior to starting MgO.ConclusionsThe results of the present study suggest that the administration of low-dose MgO to patients undergoing HD provides a means of increasing serum Mg concentration without causing dangerous hypermagnesemia, that serum Mg concentrations increase relatively easily in lower-weight patients. In addition, this study shows that low-dose MgO may be effective as an initial treatment for constipation in this patient group in a cautious manner, but this study did not provide sufficient data for the usefulness of low-dose MgO for constipation in patients undergoing HD.

Population pharmacokinetics of adebrelimab - Support of alternative flat dose regimen in extensive-stage small-cell lung cancer.

Adebrelimab, a novel anti-PD-L1 antibody, has been approved by the National Medical Products Administration of China as an intravenous infusion for use in combination with carboplatin and etoposide as first-line treatment for extensive-stage small-cell lung cancer in 2023. A two-compartment model with empirical time-varying CL for adebrelimab was established based on data from 263 patients receiving body weight-based doses from two clinical studies. Significant covariate effects of baseline body weight, albumin levels, tumor size, neutrophil counts, and presence of anti-drug antibodieswere identified on CLof debrelimab, none of which were clinically significant or warranted dose adjustment. The degree of decrease in CL was higher in patients who responded to treatment with adebrelimab than in non-responders. Adebrelimab exposures (AUC, Ctrough, or Cmax) were not identified as a statistically significant factor related to efficacy or safety endpoint in the exposure-response analysis. Distribution of simulated exposure metrics from the flat dose regimen (1200 mg q3w) was similar to the marketed weight-based dosing regimen (20 mg/kg q3w), supporting the alternative flat dose regimen in the clinic.

Cannabinoid levels description in a cohort of patients with chronic and neuropathic pain treated with Cannabis decoction: A possible role of TDM

The phytocomplex of Cannabis is made up of approximately 500 substances: terpeno-phenols metabolites, including Δ-9-tetrahydrocannabinol and cannabidiol, exhibit pharmacological activity.Medical Cannabis has several pharmacological potential applications, in particular in the management of chronic and neuropathic pain. In the literature, a few data are available concerning cannabis pharmacokinetics, efficacy and safety.Thus, aim of the present study was the evaluation of cannabinoid pharmacokinetics in a cohort of patients, with chronic and neuropathic pain, treated with inhaled medical cannabis and decoction, as a galenic preparation.In this study, 67 patients were enrolled. Dried flower tops with different THC and CBD concentrations were used: Bedrocan® medical cannabis with THC level standardized at 19% and with a CBD level below 1%, Bediol® medical cannabis with THC and CBD level standardized at similar concentration of 6.5% and 8%, respectively.Cannabis was administered as a decoction in 47 patients and inhaled in 11 patients. The blood withdrawn was obtained before the new dose administration at the steady state and metabolites plasma concentrations were measured with an UHPLC-MS/MS method.Statistically significant differences were found in cannabinoids plasma exposure between inhaled and oral administration of medical cannabis, between male and female and cigarette smokers.For the first time, differences in cannabinoid metabolites exposures between different galenic formulations were suggested in patients. Therapeutic drug monitoring could be useful to allow for dose adjustment, but further studies in larger cohorts of patients are required in order to confirm these data.

Exploring the Knowledge, Attitude, and Practice of Sudanese Medical Doctors Towards Tacrolimus, at Ahmed Gasim Hospital, Kidney Transplant Center Unit, Khartoum, Sudan (2022 – 2023)

Tacrolimus is one of the most commonly prescribed immunosuppressive drugs that varies between individuals depending on different ethnic groups, the presence of different CYP3A5 genetic variants, and the duration of time since the transplantation, which makes targeting optimal tacrolimus concentration levels more challenging. This study aimed to explore the knowledge, attitude, and practice of Sudanese medical doctors towards Tacrolimus. An observational, cross-sectional study was conducted on the Sudanese medical doctors in the nephrology clinic at Ahmed Gasim Hospital, Kidney Transplant Center Unit, Khartoum, Sudan, who were in direct contact with kidney transplant patients under tacrolimus treatment. Data were collected using a questionnaire modified to record the pharmacogenomic impact. The data were analyzed using a statistical package for social sciences (SPSS). Total of 15 medical doctors, Female 8 (53.3%) and male 7 (46.7%) with mean ± SD age of 31.60 ± (3.906). All of them were currently practicing in governmental hospitals (n=15; 83.3%), private hospitals (n=2; 11.1%), and private clinics (n=1; 6.7%). There were 67% of the medical doctors had high knowledge about the genetic profile of the patient's impact on the tacrolimus trough concentrations, while 66.7% of the medical doctors had low attitude levels toward tacrolimus. The observations among the different Sudanese ethnic groups tacrolimus trough concentrations were found to be variable, as Arabs and Fulani were observed to have low trough concentrations (n=6; 40%), while Nuba and Beja were observed to have high trough concentrations (n=5; 33.3%), instead of fur observed to had fluctuations (n=2; 13.3%). A significant correlation between practice toward tacrolimus with the location of practice, doctor specialty, and years of experience was found (P value ≤ 0.05). The medical doctors exerted a high level of knowledge about the impact of the genetic profile (metabolic alleles) in the dosing and dose adjustment of tacrolimus.

Elderly patients with advanced HER2-positive breast cancer with liver metastases benefit from low dose disitamab vedotin (RC48): case series and literature review.

Currently, although some antibody-drug conjugates have been shown to be safe and effective in the treatment of drug-resistant relapsed human epidermal growth factor receptor 2 (HER2)-positive (IHC 3+ or IHC 2+/fluorescence in situ hybridization+) breast cancer, they are already approved for clinical use in China. But the clinical needs of advanced HER2-positive patients cannot be met due to adverse reactions, drug resistance, drug accessibility and other problems, thus affecting the prognosis of patients. In particular, the representation of elderly and frail patients in randomized clinical trials is significantly under-represented. We report on two elderly women with breast cancer who developed recurrent metastatic lesions after breast cancer surgery and were again confirmed HER2-positive by histopathology and immunohistochemistry. They all developed multiple metastases in the liver after second- or third-line anti-HER2 therapy. Subsequent treatment with RC48 produced good responses and tolerable adverse reactions. One patient obtained progression-free survival for more than 7 months. Based on preliminary evidence, this study shows that RC48 in HER2-positive breast cancer with liver metastases can achieve rapid remission, thereby reducing tumor load and improving patients' quality of life. In particular, RC48 has low side effects and can be well tolerated by elderly patients after dose adjustment, providing them with treatment opportunities. It needs to be further discussed in the future research.

Anlotinib hydrochloride consolidation after concurrent chemoradiotherapy in stage III non-small-cell lung cancer: a truncated, randomized, multicenter, clinical study (ALTER-L029).

Anlotinib is an antiangiogenic drug that shows good efficacy and safety in patients with advanced non-small-cell lung cancer (NSCLC). This study aimed to explore the efficacy and safety of anlotinib for consolidation therapy in patients with stage III locally advanced, unresectable NSCLC after concurrent chemoradiotherapy (cCRT). This was a randomized, parallel-controlled, open-label, multicenter, phase II trial of patients with unresectable/nonoperated NSCLC treated with cCRT. The participants were randomized 2:1 to the anlotinib or control group. The primary endpoint was progression-free survival (PFS). The secondary endpoints were the disease control rate (DCR) and overall survival. This study was terminated early due to poor recruitment. Nine and two participants were randomly assigned to the anlotinib and control groups, respectively. One participant in the control group was excluded due to taking prohibited medications before the first efficacy evaluation. In the anlotinib group, the median age was 63 (range, 37-74) years. Two participants achieved partial response, six stable disease, and one progressive disease as best response. The DCR was 88.9%. The median PFS was 11.5 months, and the 12-month PFS rate was 33.9%. All related adverse events were grade 1 or 2. Two participants had a dose adjustment during the study. The evaluable data suggest that anlotinib alone was effective and tolerable in consolidation therapy after cCRT in patients with stage III unresectable NSCLC. The results need to be confirmed by a large-sample trial. This clinical trial was registered on www.clinicaltrials.gov (NCT03743129). Registration date: 6 September 2018.

Case Report: Methimazole-Induced Parotitis - An Unusual and Rare Presentation of Thyroid Storm

A 56-year-old female with a medical history of unspecified hyperthyroidism and a recent thyroid storm presented to the ED with tachycardia, hypertension, and bilateral enlarged parotid glands. During a previous hospitalization, she was diagnosed with unspecified hyperthyroidism and started on methimazole. During hospitalization, laboratory findings suggested Graves’ disease with an acute thyroid storm. The patient also complained of enlarged parotid glands bilaterally. CT tomography of the neck revealed no calculi of the parotid glands but showed extensive fatty replacement, possibly related to methimazole use. Treatment with propranolol and IV hydrocortisone improved thyroid function. Due to the suspicion of methimazole-induced parotitis, she was transitioned to a reduced methimazole dosage for treatment of Graves’ disease, which subsequently improved her parotitis. Methimazole, the standard initial treatment for Graves’ disease, is generally well-tolerated. It can cause adverse reactions; however, parotitis is very rare and has been documented in only a few case reports. Owing to the limited number of reports, its incidence is currently unknown. Here, we present a case of methimazole-induced parotitis as an unusual presentation of thyroid storm. Drug-induced reactions can only be considered once common causes of parotitis such as viral infection, obstruction, and autoimmune diseases are ruled out. Treatment involves dosage adjustments and supportive care. Methimazole-induced parotitis is often misdiagnosed and overlooked because of the lack of reported cases. This necessitates future research into the reaction mechanisms and optimal treatment.

Safety of deer antler extract in children: A 12-week randomized controlled clinical trial.

Deer antlers have been used as strong tonifying medicine in Asian countries, especially for the growth and development of children in pediatrics of Korean medicine. The safety of deer antler in adults cannot be applied directly to children because of their physiological characteristics. To accumulate reliable data on the safety of deer antler in pediatric populations, well-designed clinical studies are required. This research is a 12-week, randomized, double-blind, placebo-controlled clinical trial evaluating the safety of deer antler extract (DAE) in children. The DAE group received an intervention containing 1586 mg of DAE, whereas the control group received a placebo for 12 weeks. The safety was assessed by monitoring adverse drug reactions (ADRs) and laboratory test results. One hundred participants were included in the safety analysis. Three and 2 participants in the DAE and control groups, respectively, reported ADRs. There was no significant difference in incidence between the 2 groups. ADRs are categorized into gastrointestinal and skin-related symptoms. No serious ADR was observed throughout the study. The laboratory test results were within or outside the normal range at clinically insignificant levels. The research discovered that the DAE is safe in terms of ADRs and laboratory parameters under the conditions studied. Further studies are required to accumulate safety data about DAE dosage adjustment and potential interactions with other medicines.

Navigating the evolving diagnostic and therapeutic landscape of low- and intermediate-risk prostate cancer

Abstract In this nonsystematic review of the literature, we explored the changing landscape of detection and treatment of low- and intermediate-risk prostate cancer (PCa). Through emphasizing improved cancer assessment with histology classification and genomics, we investigated key developments in PCa detection and risk stratification. The pivotal role of prostate magnetic resonance imaging (MRI) in the novel diagnostic pathway is examined, alongside the benefits and drawbacks of MRI-targeted biopsies for detection and tumor characterization. We also delved into treatment options, particularly active surveillance for intermediate-risk PCa. Outcomes are compared between intermediate- and low-risk patients, offering insights into tailored management. Surgical techniques, including Retzius-sparing surgery, precision prostatectomy, and partial prostatectomy for anterior cancer, are appraised. Each technique has the potential to enhance outcomes and minimize complications. Advancements in technology and radiobiology, including computed tomography (CT)/MRI imaging and positron emission tomography (PET) fusion, allow for precise dose adjustment and daily target monitoring with imaging-guided radiotherapy, opening new ways of tailoring patients’ treatments. Finally, experimental therapeutic approaches such as focal therapy open new treatment frontiers, although they create new needs in tumor identification and tracking during and after the procedure.
