Abstract Background To evaluate the feasibility and safety of ultrasound-guided totally implantable venous access port (TIVAP) implantation via the right innominate vein in patients with breast cancer. Methods Sixty-seven breast cancer patients underwent ultrasound-guided implantation of TIVAPs via the right innominate vein for administration of chemotherapy. Clinical data including technical success, success rate for the first attempt, periprocedural, and postoperative complications were recorded and retrospectively studied. Results All patients underwent successful surgery. The success rate of the first attempt was 95.52% (64/67). The operation time was 28 to 45 min, with an average of 36 ± 6 min. Periprocedural complications included artery punctures in 1 (1.50%, 1/67) patient. Prior to this study, the mean TIVAP time was 257 ± 3 days (range 41 to 705 days). The rate of postoperative complications was 4.48% (3/67), including catheter-related infections in 1 case and fibrin sheath formation in 2 cases. Up to the present study, three people had unplanned port withdrawal due to complications, and the TIVAPs for 25 patients were still in normal use. Conclusions The success rate of ultrasound-guided TIVAPs via the right innominate vein is high with low complications, thus safe and feasible. This technique can provide a new option for chemotherapy of breast cancer patients.

The effect of catheter diameter on left innominate vein stenosis in breast cancer patients after totally implantable venous access port placement. Purpose: To evaluate the effect of catheter diameter on left innominate vein stenosis in breast cancer patients after placement of totally implantable venous access ports. Materials and methods: Totally implantable venous access ports were placed via the left internal jugular vein in 241 women with right breast cancer from January 2010 to December 2014 (mean age, 51.5 years; range, 19–83 years). There were 67 totally implantable venous access ports with a 6.5F catheter and 142 totally implantable venous access ports with an 8F catheter. Medical records were retrospectively reviewed. The presence of significant left innominate vein stenosis and tip location of the catheter was evaluated on chest computed tomography images. Statistical analysis was performed. Results: Left innominate vein stenosis developed in 1 (1.5%) and 13 (9.2%) patients after implantation with 6.5 and 8F catheters, respectively. Difference in the cumulative incidence of left innominate vein stenosis was statistically significant between the two groups (log rank test p-value: 0.002). In Cox regression analysis, the hazard ratio for left innominate vein stenosis was 20.766 ( p = 0.005) for an 8F catheter. Conclusion: The incidence of left innominate vein stenosis was higher after implantation of totally implantable venous access ports with 8F catheter rather than with 6.5F catheter. Considering that using 8F catheter versus 6.5F catheter has no advantage in terms of performance of the device, the results of our study suggest that ports with catheters >7F should be avoided.

Background: Totally implantable venous access port system (TIVAPS) is widely used in breast cancer therapy; TIVAPS has several associated complications depending on the depth of implantation in breast cancer (BC) patients during continuous infusional chemotherapy regimens. The purpose of this study is to find out the optimal depth of TIVAPS implantation to reduce the incidence of complications during infusional chemotherapy. Methods: This study reviewed the depth TIVAPS implantation in the internal jugular vein in 1282 breast cancer patients over a ten-year period (2009-2019), and associated complications. We segregated the patients as 5 groups: ‘Group A (depth < 4 mm), Group B (depth of 4-8 mm), Group C (depth of 8-12 mm), and Group D (depth of 12-16 mm), and Group E (depth of > 16 mm)’. Consequently, the ‘internal complications’ such as infection, venous thrombotic syndrome, catheter folding & migration, extravasation, whereas the ‘external complications’ viz., inflammation, local hematoma, local cutaneous reactions, and port exteriorization were significantly analyzed during TIVAPS implantation at different depths in BC patients. Results: Overall incidence of ‘internal complications’ such as infections, venous thrombotic syndrome, catheter folding & migration, and extravasation was comparatively lesser in Group C (8-12 mm) than Group A, Group B, Group D, and Group E, respectively. Mainly, the external complications such as inflammation Group C (8-12 mm) (p<0.01) were lesser (6.8%, 3/44 cases) than Group A, Group B, Group D, Group E. On a similar note, the local hematoma, and local cutaneous reaction, and port exteriorization were observed as ‘5% (1/20 cases), 4.2% (2/47 cases), and (3.2%, 1/31 cases)’ in Group C patients (p<0.01), which were comparatively lesser than the other groups. Conclusion: Subcutaneous implantation of TIVAPS at a depth of 8-12 mm could be preferred due to the lowest incidence of internal and external complications compared to the incidence of these complications in other groups; this depth could be referred to as the safe and convenient implantation depth for the effective delivery of chemotherapy regimen in BC patients without difficulty in transcutaneous access to the port.

e12557 Background: Biologic lateralization broadly impacts breast cancer. Malignancies originating in the left breast compared to the right breast tend to be more frequent, larger and of poorer prognosis. Left breast tumors respond differently to HER2-neu signaling and have lateralized Ki67 expression. In a prior study a right-left asymmetry in the neutrophil/lymphocyte ratio (NLR) of breast cancers was identified (ASCO 2018, e13094). As a follow-up, retrospective analysis of results from comprehensive genomic profiling (CGP) of right and left side breast cancer specimens was performed to determine a potential genomic etiology for the observed NLR lateralization. Methods: Tumors from 43 consecutive breast cancer patients underwent analysis for all classes of genomic alterations by hybrid capture-based CGP (Foundation Medicine). The CGP results from the 25 left- and 18 right-sided breast cancer samples were analyzed along with the histologic grade and status of estrogen receptor (ER), progesterone receptor (PR), and HER2 expression. Results: In this cohort of advanced breast cancer patients (stage 3-4), no statistically significant differences in lateralization were identified based on patient age, tumor stage, or frequency of ER or Her2 expression (Table). A predominance of PR positivity (p=0.14 chi square analysis) and amplifications in the ERBB2 (p=0.37) and RAD21 (p=0.08) genes were detected in right side tumors. Conclusions: Together with the prior study, trends in asymmetry based on genomic, pathologic, and immunohistologic differences have been detected in breast cancers, including an increased incidence of ERBB2 and RAD21 amplification in right-side breast tumors in this cohort. The predominance of lower PR positivity in the left breast tumors may be due to preferential hypermethylation, consistent with reports that it mediates biologic lateralization changes, downregulates PR expression, and alters amplification rates. Epigenetic methylation, may contribute to asymmetric breast cancer biology and have implications for therapeutic strategy. Further study is warranted.[Table: see text]

Background. Breast cancer treatment has rapidly changed in the last few years. Particularly, treatment of patients with axillary nodal involvement has evolved after publication of several randomized clinical trials. Omitting axillary lymph node dissection in selected early breast cancer patients with one or two positive sentinel nodes did not compromise overall survival nor regional disease control in these trials. Hence, either excluding or identifying extensive axillary nodal involvement becomes increasingly important. Purpose. To evaluate whether the current diagnostic modalities can accurately identify or exclude extensive axillary nodal involvement. Evaluated modalities were axillary ultrasound, ultrasound-guided needle biopsy, MRI, and PET/CT. Methods. A literature search was performed in the Cochrane Library, EMBASE, and PubMed databases up to June 2019. The search strategy included terms for breast cancer, lymph nodes, and the different imaging modalities. Only articles that reported pathological N-stage or the total number of positive axillary lymph nodes were considered for inclusion. Studies with patients undergoing neoadjuvant systemic therapy were excluded. Conclusion. There is no evidence that any of the current preoperative axillary imaging modalities can accurately exclude or identify breast cancer patients with extensive nodal involvement. Both negative PET/CT and negative MRI scans (with gadolinium-based contrast agents) are promising in excluding extensive nodal involvement. Larger studies should be performed to strengthen this conclusion. False-negative rates of axillary ultrasound and ultrasound-guided needle biopsy are too high to rely on negative results of these modalities in excluding extensive nodal involvement.
