Tumor-infiltrating lymphocytes (TILs) might be associated with host-cell mediated immunity, which could be partly reflected by peripheral blood cell counts. In addition, lymphocyte-predominant breast cancer (LPBC), which was defined as tumors having high TIL levels, showed a favorable prognosis among triple-negative breast cancer or HER2-positive breast cancer. We aimed to investigate whether peripheral blood cell counts are associated with LPBC.

The Trento screening program transitioned to digital breast tomosynthesis (DBT) screening based on evidence that DBT improves breast cancer (BC) detection compared to mammography; an evaluation of the transition to DBT is reported in this pilot study.

Background: Studies based on large-volume databases have made significant contributions to research on breast cancer surgery. To date, no comparison between large-volume databases has been made internationally. This is the first proof-of-concept study exploring the feasibility of combining two existing operational databases of The Netherlands and the United States, focusing on breast cancer care and immediate breast reconstruction specifically.313/291
Methods: The National Breast Cancer Organization The Netherlands Breast Cancer Audit (NBCA) (2011 to 2015) and the U.S. Surveillance, Epidemiology, and End Results (SEER) database (2010 to 2013) were compared on structure and content. Data variables were grouped into general, treatment-specific, cancer-specific, and follow-up variables and were matched. As proof-of-concept, mastectomy and immediate breast reconstruction rates in patients diagnosed with invasive breast cancer or ductal carcinoma in situ were analyzed.
Results: The NBCA included 115 variables and SEER included 112. The NBCA included significantly more treatment-specific variables (n = 46 versus 6), whereas the SEER database included more cancer-specific variables (n = 74 versus 26). In patients diagnosed with breast cancer or ductal carcinoma in situ, immediate breast reconstruction was performed in 19.3 percent and 24.0 percent of the breast cancer cohort and 44.0 percent and 35.3 percent of the ductal carcinoma in situ cohort in the NBCA and SEER, respectively. Immediate breast reconstruction rates increased significantly over time in both data sets.
Conclusions: This study provides a first overview of available registry data on breast cancer care in The Netherlands and the United States, and revealed limited data on treatment in the United States. Comparison of treatment patterns of immediate breast reconstruction showed interesting differences. The authors advocate the urgency for an international database with alignment of (treatment) variables to improve quality of breast cancer care for patients across the globe.

In the first-line or second-line setting, CDK4/6 inhibitors plus hormone therapies are better than standard hormone therapies in terms of progression-free survival. Moreover, no chemotherapy regimen with or without targeted therapy is significantly better than CDK4/6 inhibitors plus hormone therapies in terms of progression-free survival. Our data support treatment guideline recommendations involving the new combinations of hormone therapies plus targeted therapies as first-line or second-line treatments, or in both settings, in women with hormone-receptor-positive, HER2-negative metastatic breast cancer.

[News] Pyrotinib versus lapatinib in HER2-positive breast cancer



The Lancet Oncology by Elizabeth Gourd 

NEWS| VOLUME 20, ISSUE 10, PE562, OCTOBER 01, 2019

Patients with previously treated HER2-positive relapsed or metastatic breast cancer have significantly better outcomes when treated with pyrotinib plus capecitabine than with lapatinib plus capecitabine, according to a recent study.

A Simplified Cost-Utility Analysis of Inpatient Flap Monitoring after Microsurgical Breast Reconstruction and Implications for Hospital Length of Stay



by Jablonka, Eric M.; Lamelas, Andreas M.; Kanchwala, Suhail K.; Rhemtulla, Irfan; Smith, Mark L

Plastic and Reconstructive Surgery: October 2019 - Volume 144 - Issue 4 - p 540e-549e

Background: The number of free flap take-backs and successful salvages following microsurgical breast reconstruction decreases as time from surgery increases. As a result, the cost of extended inpatient monitoring to achieve a successful flap salvage rises rapidly with each postoperative day. This study introduces a simplified cost-utility model of inpatient flap monitoring and identifies when cost-utility exceeds the thresholds established for other medical treatments.
Methods: A retrospective review of a prospectively maintained database was performed of patients who underwent microsurgical breast reconstruction to identify flap take-back and salvage rates by postoperative day. The number of patients and flaps that needed to be kept on an inpatient basis each day for monitoring to salvage a single failing flap was determined. Quality-of-life measures and incremental cost-effectiveness ratios for inpatient flap monitoring following microsurgical breast reconstruction were calculated and plotted against a $100,000/quality-adjusted life-year threshold. Results: A total of 1813 patients (2847 flaps) were included. Overall flap take-back and salvage rates were 2.4 percent and 52.3 percent, respectively. Of the flaps taken back, the daily take-back and salvage rates were 56.8 and 60.0 percent (postoperative day 0 to 1), 13.6 and 83.3 percent (postoperative day 2), 11.4 and 40.0 percent (postoperative day 3), 9.1 and 25.0 percent (postoperative day 4), and 9.1 and 0.0 percent (>postoperative day 4), respectively. To salvage a single failing flap each day, the number of flaps that needed to be monitored were 121 (postoperative day 0 to 1), 363 (postoperative day 2), 907 (postoperative day 3), 1813 (postoperative day 4), and innumerable for days beyond postoperative day 4. The incremental cost-effectiveness ratio of inpatient flap monitoring begins to exceed a willingness-to-pay threshold of $100,000/quality-adjusted life-year by postoperative day 2.
Conclusion: The health care cost associated with inpatient flap monitoring following microsurgical breast reconstruction begins to rise rapidly after postoperative day 2.

Background: The deep inferior epigastric artery perforator (DIEP) flap is considered the gold standard in autologous breast reconstruction. In bilateral cases, both flaps are often anastomosed to the internal mammary vessels on either side of the sternum. The authors propose a method in which both flaps are anastomosed to only the right side internal mammary artery and vein.
Methods: Between November of 2009 and March of 2018, 125 patients underwent bilateral DIEP flap breast reconstruction with this technique. One flap is perfused by the anterograde proximal internal mammary artery and the second one by the retrograde distal internal mammary artery after presternal tunneling. Patient demographics and operative details were reviewed retrospectively. Results: Two hundred fifty flaps were performed. One hundred fifty-two flaps were prophylactic or primary reconstructions (60.8 percent), 70 were secondary reconstructions (28 percent), and 28 were tertiary reconstructions (11.2 percent). Mean patient age was 46 years, and the mean body mass index was 25 kg/m2. Sixty patients underwent radiation therapy or chemotherapy (48 percent). The authors encountered one significant partial failure (0.4 percent) and nine complete flap failures (3.6 percent). The authors did not see a statistically significant predisposition for failure comparing the retrograde with the anterograde flow flaps, nor when comparing the tunneled with the nontunneled flaps.
Conclusions: The authors’ results show that anastomosing both DIEP flaps to a single set of mammary vessels is safe and reliable. The authors conclude that the retrograde flow through the distal internal mammary artery is sufficient for free flap perfusion and that subcutaneous tunneling of a free flap pedicle does not predispose to flap failure. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
