Analysis of the efficacy and tolerability of FOLFIRINOX chemotherapy treatment in patients over 65 years of age with diagnosis of advanced adenocarcinoma of the pancreas.

Introduction: Systemic treatment of pancreatic adenocarcinoma in the population of people over 65 years old is a challenge resulting from both the extremely unfavourable prognosis of this cancer and the particularly high sensitivity to the toxicity of chemotherapy in the elderly. This article presents the effectiveness and side effects of first-line chemotherapy according to the FOLFIRINOX regimen in patients over 65 years of age diagnosed with advanced pancreatic adenocarcinoma. Material and methods: The analysis was conducted in a group of 43 patients diagnosed with locally advanced inoperable pancreatic cancer or metastatic pancreatic cancer. Patients were treated between 2017 and 2021 in the Clinical Oncology Department, University Clinical Centre, Katowice, Poland. Results: In the study group, the median overall survival was 9.8 months; the median progression-free survival was 8.8 months. Treatment toxicity occurred in all patients. Adverse events of G3 and G4 severity (common terminology criteria for adverse events 5.0) occurred in 8% of patients. In 2 patients (5%), chemotherapy toxicity was the reason for discontinuation of systemic treatment. Conclusions: Triple-drug chemotherapy in a group of patients aged over 65 years with a diagnosis of advanced pancreatic cancer shows similar effectiveness to the general treated population, and with proper medical supervision the severity of side effects is at an acceptable level.

Clinical Value of Circulating miRNA in Diagnosis, Prognosis, Screening and Monitoring Therapy of Pancreatic Ductal Adenocarcinoma-A Review of the Literature.

Pancreatic cancer (PC) is considered to be the seventh most common cause of cancer-related deaths. The number of deaths caused by PC is estimated to increase in the future. An early diagnosis of PC is crucial for improving treatment outcomes. The most common histopathological subtype of PC is pancreatic ductal adenocarcinoma (PDAC). MicroRNAs (miRNAs)-which are endogenous non-coding RNAs involved in the posttranscriptional regulation of multiple gene expression-constitute useful diagnostic and prognostic biomarkers in various neoplasms, including PDAC. Circulating miRNAs detected in a patient's serum or plasma are drawing more and more attention. Hence, this review aims at evaluating the clinical value of circulating miRNA in the screening, diagnosis, prognosis and monitoring of pancreatic ductal adenocarcinoma therapy.

The superficial temporal artery: A meta-analysis of its prevalence and morphology.

INTRODUCTION: The superficial temporal artery (STA) is a terminal branch of the external carotid artery. It supplies the regions of scalp and face. The morphometrical data concerning STAs are not consistent; therefore, in this systemic review and meta-analysis, we aimed in this to provide an up-to-date data on its anatomic features. MATERIAL AND METHODS: In order to do this, PubMed, Embase, ScienceDirect, and Web of Science were searched. We followed the Preferred Reporting Items and Review and Meta-Analyses guidelines for the meta-analysis. Studies that reported the prevalence and anatomical data regarding STA were included in further analyses. RESULTS: Out of 1,446 studies initially evaluated, 21 were included in the meta-analysis (874 patients/donors). The STA diameter was 1.5 mm (95% confidence interval [CI]: 1.47-1.53 mm). The frontal and parietal branches of the STA were present in 97.6% (95% CIs: 94.6-99.5%) and 96.4% (95% CIs: 93.5-98.5%) of the cases, respectively. The STA bifurcation point was located above the zygomatic arch in 79.1% (95% CI: 68.0-84.3), below the zygomatic arch in 6.7% (95% CI: 2.4-12.1), and on the zygomatic arch in 11.1% of the cases (95% CI: 5.4-17.5). There was no bifurcation of the STA in 3.1% of the cases (95% CI: 0.4-7.3). CONCLUSION: The most comprehensive analysis of STA morphological features is presented. The results from this evidence-based anatomical study will improve understanding of the clinical STA anatomy, which in turn has major implications for understanding the STA in clinical practice.

Endovascular treatment of middle cerebral artery aneurysms - single-centre results.

PURPOSE: The middle cerebral artery (MCA) is the second most common location of intracerebral aneurysms. Traditionally, they are treated by microsurgical clipping, but with the development of new techniques and devices endovascular embolisation is gaining more importance. The aim of this study was to summarise six years of experience of our department in endovascular treatment of MCA aneurysms. MATERIAL AND METHODS: Forty patients with 41 MCA aneurysms treated in a single centre were included in this study. Data on patients' comorbidities, aneurysm morphology, and treatment course were collected, with special emphasis on complications. RESULTS: There were no statistically significant differences in terms of aneurysm morphology between males and females and between ruptured and unruptured aneurysms. None of the diseases analysed in the current study were linked with significantly increased risk of SAH. Unruptured aneurysms were significantly more frequently treated by stent-assisted coiling (30.4% vs. 5.6%, p = 0.0388) than were ruptured aneurysms, while ruptured aneurysms were treated more frequently by coiling alone (77.8% vs. 34.8%, p = 0.0062). After an initial course of treatment 63.4% (n = 26) of patients had class I in Raymond-Roy occlusion classification, 22% (n = 9) had class II, and 14.6% (n = 6) had class III. Complications of the procedure were observed in 17.5% (n = 7) of patients: 22.2% (n = 4) with ruptured and 13.6% (n = 3) with unruptured aneurysms. CONCLUSIONS: Endovascular treatment of MCA aneurysms is feasible, and our results are convergent with other studies. Ruptured MCA aneurysms may be treated endovascularly with similar effects as unruptured MCA aneurysms. The complication rate of such treatment is low.

Anatomical Map of the Facial Artery for Facial Reconstruction and Aesthetic Procedures.

BACKGROUND: The facial artery (FA) is the main blood vessel supplying the anterior face and an understanding of its anatomy is crucial in facial reconstruction and aesthetic procedures. OBJECTIVES: The aim of this study was to assess the many anatomical features of the FA utilizing a multidimensional approach. METHODS: Head and neck computed tomographic angiographies of 131 patients (255 FAs) with good image quality were evaluated. The FA was classified according to its termination pattern, course, and location with reference to soft tissue/bone surrounding structures. RESULTS: In total, each branch was present as follows: the submental artery (44.8%), the inferior labial artery (60%), the superior labial artery (82.2%), the lateral nasal artery (25.1%), and the angular artery (42.5%). The most common FA course was the classic course, situated medially to the nasolabial fold (27.1%). In total 65.5% of the arteries were located medially to the nasolabial fold, and only 12.3% of them were totally situated lateral to the nasolabial fold. The median distance (with quartiles) from the inferior orbital rim reached the FA after the superior labial artery branched off in 50.2% of cases and was 36.6 mm (33.4; 43.3). The angle between the FA and the inferior border of the mandible was 49.8o (31.9; 72.4). The horizontal distances between the oral commissure and naris to the FA were 8.5 ± 4.0 mm and 12.1 ± 6.7 mm, respectively. CONCLUSIONS: An anatomical map summarizing the major measurements and geometry of the FA was generated. The detailed anatomy and relative positioning of the FA should be considered to avoid any unexpected complications in plastic surgery.

The transverse facial artery anatomy: Implications for plastic surgery procedures.

BACKGROUND: The transverse facial artery (TFA) perfuses the lateral face. Knowledge of topographical anatomy of the lateral face is crucial for safe procedural performance in aesthetic and plastic surgery, especially the face lift flap and face transplant. The aim of the present study was to assess detailed TFA morphometrical features. PATIENTS AND METHODS: One-hundred computed tomography head angiographies were analyzed. TFA numbers and origins were recorded bilaterally (200 cases). TFA diameters and lengths in addition to their positions in relation to neighboring vessels and the zygomatic arches were measured. RESULTS: TFA was present in 96% of cases (192/200, left = 97, right = 95). A single TFA was present in 95.3% and double TFAs were present in 4.7% of cases. In 91.7%, the TFA originated from the superficial temporal artery, and in 3.1%, it originated from the external carotid artery. One left TFA originated from the maxillary artery. The TFA was significantly longer on the right than on the left side (56.6±26.0 versus 47.3±22.2 mm; p = 0.03). The TFA mean diameter was 1.0±0.4 mm (range: 0.4-2.2 mm) with no difference between face sides. TFA length correlated with its diameter (r = 0.46, p <0.05). The TFA always originated below the zygomatic arch, and it should be found in the 8.8 mm wide area beginning 17.0mm below the lower border of the zygomatic arch. CONCLUSIONS: The TFA has a significant role in lateral face vascularization, and absence of this vessel is very uncommon.

The Superficial Temporal Artery: Anatomical Map for Facial Reconstruction and Aesthetic Procedures.

BACKGROUND: The superficial temporal artery (STA), a terminal branch of the external carotid artery, supplies multiple regions of the scalp and face. Knowledge of the STA is important for reconstructive and aesthetic procedures of the head and face. OBJECTIVES: The aim of this study was to map the STA in relation to anatomical landmarks. METHODS: Computed tomographic head angiographies of 215 patients were included in this study; the final analysis comprised 419 STAs. The STA's main branches and variants were identified. The diameters of the STA and its frontal and occipital branches were measured, and the distance between the STA tree and anatomical landmarks was delineated. RESULTS: Frontal and parietal branches were recorded in 98.1% and 90.7% of patients, respectively. The mean diameters, measured 1 and 7 cm from the STA bifurcation for the frontal branch, were 0.97 ± 0.32 and 0.81 ± 0.26 mm, respectively, and for the parietal branch, the diameters were 0.96 ± 0.28 and 0.76 ± 0.23 mm, respectively. The STA bifurcation point was located above the zygomatic arch (ZA) in 75.6%, below in 14.7%, and on the ZA in 9.7% of patients. The mean distance from the ZA center to the STA bifurcation was 16.8 ± 16.0 mm. CONCLUSIONS: The STA artery and its main branches follow a conservative course, and serious anatomical variations are relatively rare. The STA and its main branches may be localized using simple anatomical landmarks. An anatomical map showing artery-free zones in the lateral forehead region was presented, which may prove useful for plastic, reconstructive, and aesthetic surgeons.Level of Evidence: 4.
