Comparison of PICC and TIVAP in chemotherapy for patients with thyroid cancer

Machine learning risk prediction model for bloodstream infections related to totally implantable venous access ports in patients with cancer

Objective

This study aimed to develop and validate a machine learning-based risk prediction model for catheter-related bloodstream infection (CRBSI) following implantation of totally implantable venous access ports (TIVAPs) in patients.

Methods

A retrospective cohort study design was employed, utilizing the R software package mlr3. Various algorithms including logistic regression, naive Bayes, K nearest neighbor, classification tree, and random forest were applied. Addressing class imbalance, benchmarks were used, and model performance was assessed using the area under the curve (AUC). The final model, chosen for its superior performance, was interpreted using variable importance scores. Additionally, a nomogram was developed to calculate individualized risk probabilities, enhancing clinical utility.

Results

The study involved 755 patients across both development and validation cohorts, with a TIVAP-CRBSI rate of 14.17%. The random forest model demonstrated the highest discrimination ability, achieving a validated AUC of 0.94, which was consistent in the validation cohort.

Conclusions

This study successfully developed a robust predictive model for TIVAP-CRBSI risk post-implantation. Implementation of this model may aid healthcare providers in making informed decisions, thereby potentially improving patient outcomes.

Central venous access device terminologies, complications, and reason for removal in oncology: a scoping review

BACKGROUND

Lack of agreed terminology and definitions in healthcare compromises communication, patient safety, optimal management of adverse events, and research progress. The purpose of this scoping review was to understand the terminologies used to describe central venous access devices (CVADs), associated complications and reasons for premature removal in people undergoing cancer treatment. It also sought to identify the definitional sources for complications and premature removal reasons. The objective was to map language and descriptions used and to explore opportunities for standardisation.

METHODS

A systematic search of MedLine, PubMed, Cochrane, CINAHL Complete and Embase databases was performed. Eligibility criteria included, but were not limited to, adult patients with cancer, and studies published between 2017 and 2022. Articles were screened and data extracted in Covidence. Data charting included study characteristics and detailed information on CVADs including terminologies and definitional sources for complications and premature removal reasons. Descriptive statistics, tables and bar graphs were used to summarise charted data.

RESULTS

From a total of 2363 potentially eligible studies, 292 were included in the review. Most were observational studies (n = 174/60%). A total of 213 unique descriptors were used to refer to CVADs, with all reasons for premature CVAD removal defined in 84 (44%) of the 193 studies only, and complications defined in 56 (57%) of the 292 studies. Where available, definitions were author-derived and/or from national resources and/or other published studies.

CONCLUSION

Substantial variation in CVAD terminology and a lack of standard definitions for associated complications and premature removal reasons was identified. This scoping review demonstrates the need to standardise CVAD nomenclature to enhance communication between healthcare professionals as patients undergoing cancer treatment transition between acute and long-term care, to enhance patient safety and rigor of research protocols, and improve the capacity for data sharing.

Application value of modified skin expansion in PICC catheterization under the guidance of B-ultrasound in gastrointestinal cancer patients with chemotherapy

OBJECTIVE

To investigate the clinical value of modified skin expansion in peripherally inserted central venous catheter (PICC) catheterization under the guidance of B-ultrasound in gastrointestinal cancer patients with chemotherapy.

METHODS

In this retrospective study, 60 gastrointestinal cancer patients with chemotherapy were included and divided into an experimental group (treated with modified skin expansion in PICC catheterization under the guidance of B-ultrasound) and a control group (treated with the longitudinal skin expansion in PICC catheterization under the guidance of B-ultrasound). The bleeding volume, pain score, success rate of one-time PICC catheterization and the incidence of complication were compared between the two groups.

RESULTS

The modified skin expansion in PICC catheterization under the guidance of B-ultrasound had obvious effect on gastrointestinal cancer patients with chemotherapy. The VAS scores were significantly lower after PICC catheterization in the experimental group compared with the control group (P < 0.05). The success rate of one-time PICC catheterization in the experimental group was significantly higher than that in the control group. Moreover, the incidence of complication and massive bleeding during puncture and 24 hours after puncture was significantly lower in the observation group compared with that in the control group.

CONCLUSIONS

Modified skin expansion in PICC catheterization under the guidance of B-ultrasound in gastrointestinal cancer patients with chemotherapy can improve the success rate of one-time sheath delivery, effectively reduce the amount of blood leakage after catheterization, reduce patients' pain and reduce the incidence of complications.

Effects of Peripherally Inserted Central Catheter (PICC) Catheterization Nursing on Bloodstream Infection in Peripheral Central Venous Catheters in Lung Cancer: A Single-Center, Retrospective Study

Background. Peripherally inserted central catheter (PICC), as one of the important intravenous routes for the rescue and treatment of critically ill patients, has been widely used in the fluid resuscitation of critically ill patients in intensive care. In particular, PICC can be widely used in the treatment of cancer patients. With the wide application of peripheral central venous catheterization, the clinical findings of bloodstream infection complications caused by PICC have gradually attracted the attention of doctors and patients. Aims. To investigate the effect of specialized placement and PICC placement care on patients with lung cancer who underwent PICC puncture. Patients were selected and divided into a comparison group and an observation group of 40 patients each according to the randomized residual grouping method. In the comparison group, routine PICC placement and catheter maintenance were performed, while the observation group was provided with specialized placement and PICC placement care. The differences in immune and tumor marker levels and nursing compliance between the two groups were observed and compared before and after nursing care. Results. There was no significant difference in the comparison of tumor marker levels between the two groups of patients before care, while the levels of CYFRA21-1, CA125, and VGEF in the observation group were significantly lower than those in the comparison group after care, and this difference was statistically significant ( $P<0.05$ ). There was no statistically significant difference in the comparison of immune levels between the two groups before care ( $P>0.05$ ), while the comparison of CD4+, CD3+, and CD4+/CD8+ after care was significantly different and higher in the observation group than in the comparison group, and the comparison was statistically significant ( $P<0.05$ ). The compliance rate of 93.8% in the observation group was significantly higher than that of 77.9% in the comparison group, and this difference was statistically significant for comparison ( $P<0.05$ ). Conclusion. PICC placement care is more effective in patients with lung cancer and performing PICC puncture, significantly improves patients’ immune and tumor marker levels, improves patients’ negative emotions, reduces disease uncertainty, and improves nursing compliance.

Retrospective analysis: 5509 cases of "totally implantable venous access port systems implantation (TIVAPS) depth" assisted by digital radiography

PURPOSE

Modern oncological treatment in breast cancer patients requires the precise delivery of chemotherapy infusion into the central venous systems without toxicity. TIVAPS is the significant method of chemotherapy delivery although certain internal or external complications associated with their placement. However, the long-term use of TIVAPS is still a concern to minimize the complications such as venous thrombosis syndrome (VTS) and cardiac defects. The aim of this study is to investigate the potential disadvantages that may be avoided by digital radiography (DR)-assisted measurement of catheter depth pertinent to TIVAPS implanted system.

METHODS

Retrospective analysis related to 5509 TIVAPS recipients of 99% female breast cancer patients and 1% male blood disorder patients registered from April 2013 to November 2017 were included in the study. Patients with TIVAPS catheter tip depth into superior vena cava into upper (group A), middle (group B), and lower (group C) parts were stratified for evaluation during implantation; DR-assisted measurement of TIVAPS was performed to decipher "tip depth of catheter" and determined the relevance of tip depth to complications such as VTS and cardiac defects.

RESULTS

Incidence of VTS complications were significantly higher in TIVAPS recipients of group A (82.7%) than group B (16%) and group C (0.12%) in which the "tip depth of TIVAPS was deeper" (P < 0.01). Defects in heart function are higher in group C (59.6%) than group A (15.8%) and group B (24.6%) in which the "tip depth of TIVAPS was deeper" (P < 0.01).

CONCLUSION

DR-assisted measurement can more accurately determine the depth of TIVAPS catheter implantation, and avoid the incidence of related complications, and provide a better method for surgeons.

Construction of a rabbit model with vinorelbine administration via peripherally inserted central catheter and dynamic monitoring of changes in phlebitis and thrombosis

Peripherally inserted central catheters (PICCs) are used for the administration of chemotherapy drugs, including vinorelbine. The present study aimed to construct a rabbit model with vinorelbine administration via PICC, and to dynamically monitor the formation of phlebitis and thrombosis. PICC was inserted into 48 rabbits following specific clinical procedures. The rabbits were randomly divided (n=6 per group) into the following eight groups: i) Control (PICC in place for 1 day); ii) 2nd day of PICC placement (received the first cycle of vinorelbine administration); iii) 3rd day of PICC placement; iv) 7th day of PICC placement; v) 14th day of PICC placement; vi) 21st day of PICC placement; vii) 23rd day of PICC placement (received the second cycle of vinorelbine administration); and viii) 24th day of PICC placement. Hematoxylin and eosin staining was performed on catheter, ear vein and anterior vena specimens. Prothrombin time was measured using an automatic coagulation analyzer, followed by routine blood tests. Serum levels of inflammation- and thrombosis-related factors, including C-reactive protein, D-dimer, interleukin-2, interleukin-6, P-selectin and E-selectin, were measured using ELISAs. X-ray examination confirmed that the rabbit model with vinorelbine administration via PICC was successfully constructed. On the 1st and 23rd day of PICC placement, thrombosis was observed in the catheter. Furthermore, on the 1st day of PICC placement, thrombosis was clearly observed in the ear vein and anterior vena samples. After vinorelbine administration, phlebitis occurred in the ear vein and anterior vena cava samples. With increasing time after vinorelbine administration via PICC, thrombosis and phlebitis were notably ameliorated. Moreover, on the day of vinorelbine administration, prothrombin time was significantly decreased and the serum levels of inflammation- and thrombosis-related factors were significantly increased compared with previous days. Collectively, the present study observed the formation and specific evolution of phlebitis and venous thrombosis after vinorelbine administration, providing a reference for the early prediction, timely prevention and treatment of PICC-related chemotherapy complications.

Comparison of the Quality of Life of Patients with Breast or Colon Cancer with an Arm Vein Port (TIVAD) Versus a Peripherally Inserted Central Catheter (PICC)

Introduction: Venous access is a crucial element in chemotherapy delivery. It remains unclear whether cancer patients prefer a port to a peripherally inserted central catheter (PICC). Our study aimed to assess cancer patients’ satisfaction with their venous access device and to compare the quality of life (QoL) of subjects with a PICC to those with a port. Methods: In this prospective cohort study, EORTC QLQ-C30, and a locally developed quality of life survey (QLAVD), designed to assess satisfaction with venous access devices, were administered to breast or colorectal cancer patients over a one-year period following the device insertion. Mixed effects models were used to assess changes on mean scores at different time points. Results: A total of 101 patients were recruited over a three-year period, (PICC group, n = 50; port group, n = 51). Survey response rates for months one and three were 72% and 48%, respectively. Overall, no significant differences were noted between the two groups in relation to EORTC QOL. At three months, the mean pain scores were 3.5 ± 2.3 for the port and 1.3 ± 0.75 for PICC (<0.001). The mean score for a negative effect of the venous access device on psychosocial well-being was 6.0 ± 4.1 for PICC and 3.0 ± 2.7 for the port (p = 0.005). Complications related to PICCs occurred in 38% patients versus 41% with a port (p > 0.24). Conclusions: Although subjects with a port experienced more pain during the device insertion or access for chemotherapy, it had a smaller negative impact on psychosocial scores than the PICC. No significant differences in complications rates were observed between the two devices.
