Serum Prolactin Levels as a Novel, Practical Marker for Predicting Malignant Diseases of the Breast.

Background and objective Prolactin (PRL) has a high specificity toward breast cancer (BC), making it a valuable marker in both diagnosis and prognosis. In this study, we aimed to compare serum PRL levels between pre- and post-menopausal women with BC, as well as normal reference values. We also investigated the association of various risk factors with PRL levels in women with BC. Methods The study involved adult women diagnosed with BC based on clinical features and tissue histopathology receiving treatment at a tertiary care center in Pune, India. General and demographic information, anthropometric measurements (height, weight, and BMI), menstrual status (age at menarche and menopausal state), clinical presentation (signs and symptoms), duration of symptoms, and parity were recorded by using a pre-tested proforma based on hospital records or in-person interviews. Serum PRL was measured by the RIA method (sandwich assay). Results A total of 67 women (average age: 47.5 ± 11.8 years; 33 of them post-menopausal) with BC were included in the study. The participants had an average BMI of 24.9 ± 3.5 kg/m2, and 26 (39%) of them were overweight. The majority of women had BC stage IIA disease, involvement of the right side or upper outer quadrant, and had attained menarche after 14 years of age; 47 women had a BC duration of >3 months. Seven women were nulliparous, and the remaining had given birth to their first child before the age of 26 years. The average serum PRL level among the participants was 9.27 ± 7.62 ng/mL, with higher levels found in post-menopausal women compared to pre-menopausal women (11.08 vs. 7.51 ng/mL, respectively; p=0.08). Women with a higher stage and greater duration of disease had significantly higher serum PRL levels (p<0.001 for both). When compared with reference values, pre-menopausal women showed significantly lower (6.25 vs. 10.9, respectively; p=0.001) and post-menopausal women showed significantly higher (8.55 vs. 5.95; p=0.004) serum PRL levels. A positive correlation was found between serum PRL and age at the time of birth of the first child (p=0.068). Conclusions Based on our findings, PRL is an important hormone in the development of BC in women. Therapeutic modulation of PRL may be a realistic and novel approach to curing human BC, either administered alone or in combination with conventional treatments.

Next-Generation sequencing transforming clinical practice and precision medicine.

Next-generation sequencing (NGS) has revolutionized the field of genomics and is rapidly transforming clinical diagnosis and precision medicine. This advanced sequencing technology enables the rapid and cost-effective analysis of large-scale genomic data, allowing comprehensive exploration of the genetic landscape of diseases. In clinical diagnosis, NGS has proven to be a powerful tool for identifying disease-causing variants, enabling accurate and early detection of genetic disorders. Additionally, NGS facilitates the identification of novel disease-associated genes and variants, aiding in the development of targeted therapies and personalized treatment strategies. NGS greatly benefits precision medicine by enhancing our understanding of disease mechanisms and enabling the identification of specific molecular markers for disease subtypes, thus enabling tailored medical interventions based on individual characteristics. Furthermore, NGS contributes to the development of non-invasive diagnostic approaches, such as liquid biopsies, which can monitor disease progression and treatment response. The potential of NGS in clinical diagnosis and precision medicine is vast, yet challenges persist in data analysis, interpretation, and protocol standardization. This review highlights NGS applications in disease diagnosis, prognosis, and personalized treatment strategies, while also addressing challenges and future prospects in fully harnessing genomic potential within clinical practice.

Robot-assisted simple prostatectomy for prostates greater than 100 g.

PURPOSE: Efforts are ongoing to treat severe benign prostatic hyperplasia as traditional endoscopic treatment options are often difficult to perform and associated with significant complications. This manuscript highlights our initial experience of robot-assisted simple prostatectomy [RASP] with minimum a year follow-up. We also compared our outcomes with published literature. METHODS: After an Institution Review Board approval, we gathered data of 50 cases of RASP between Jan 2014 and May 2021. Patients with prostate volume > 100 cc [calculated from magnetic resonance imaging (MRI)] and prostate biopsy confirmed benign prostate were candidates for RASP. Patients underwent RASP via transperitoneal route either by suprapubic or trans-vesical approach. Preoperative demographics, peri-operative parameters and post-operative parameters such as hospital stay, catheter removal, urinary continence and uroflow were recorded in standard database and presented as descriptive statistics. RESULTS: Patients presented with a baseline median International Prostate Symptom Score (IPSS) of 23 (inter-quartile range (IQR) 21,25) and a median PSA of 7.7 ng/ml (IQR 6.4,8.7). Median preoperative prostate volume was 167 ml (IQR, 136,198 ml). Median console time was 118 min, and median estimated blood loss was 148 ml (IQR 130, 167 ml). None of our cohort needed intraoperative transfusion, conversion to open surgery or developed any complications. Median time to Foley removal was 10 days (IQR 8,12). Significant drop in the IPSS score and improvement in Qmax was noted over the period of follow-up. CONCLUSION: RASP is associated with considerable improvements in urinary symptoms. However, comparative studies with endoscopic treatment options of large prostatic adenomas are warranted and ideally include cost analysis of different procedures.

Technical Tips in Managing Large Median Lobes During Robot-assisted Radical Prostatectomy.

Prostate cancer surgeons are commonly faced by a technically challenging situation dealing with prostate cancer having large median lobes. Patients with large median lobes often have larger prostates, which makes it difficult to visualize anatomical planes during robot-assisted radical prostatectomy (RARP). Herein, we described our experience in dealing with large median lobes during RARP. We have focused on technical tips to avoid complications and facilitate a smooth procedure in patients with large median lobes during RARP. A total of 2671 patients who underwent RARP were divided into two groups based on the presence or absence of a protruded median lobe (PML): group A (2411 patients without a PML) and group B (260 patients with a PML). All patients underwent preoperative magnetic resonance imaging and final intraoperative confirmation for the presence of a PML. Pre-, intra-, and postoperative parameters were compared in two groups using the Student t test and two-proportion t test as appropriate. Patients in group B have statistically significantly higher median prostate-specific antigen (PSA; 7.7 vs 5.8 ng/dl), PSA density (0.17 vs 0.09), and International Prostate Symptom Score (19.5 vs 7.2); longer median console time (114 vs 134 min) and surgery time (145 vs 170 min); and higher blood loss (150 vs 175 ml) than those in group A. There were no statistically significant differences in pathological stages (T2, T3; 87%, 13% vs 88%, 12%) and rates of positive surgical margins (7% vs 8.5%) between groups A and B. Single-center and retrospective design was the major limitation of our study. We conclude that understanding the key steps to facilitate bladder neck dissection is vital to avoid serious intraoperative events and to maximize outcomes. Patient summary: In this report, we looked at our robotic radical prostatectomy cohort with large median lobes. We found that surgery in these patients requires more time and blood loss, but similar cancer control. We conclude that following the key steps are important to avoid complications.
