Background: The management of capecitabine-related hand-foot syndrome (HFS) is critical to avoid progression of the syndrome through early detection and early response; management of HFS involves joint medication management by physicians and pharmacists (hospital and community pharmacists). This study aimed to evaluate the effectiveness of collaborative medication management in cancer patients with HFS by comparing its effectiveness with the traditional response using monitoring reports from community pharmacists.

Patients And Methods: Medical records of 120 breast cancer patients who received capecitabine therapy between September 2017 and August 2023 were retrospectively reviewed.

Purpose: This study aimed to determine whether the 21-Gene Breast Recurrence Score® assay from primary breast tissue predicts the prognosis of patients with hormone receptor-positive and human epidermal growth factor 2-negative advanced breast cancers (ABCs) treated with fulvestrant monotherapy (Group A) and the addition of palbociclib combined with fulvestrant (Group B), which included those who had progression in Group A from the Japan Breast Cancer Research Group-M07 (FUTURE trial).

Methods: Progression-free survival (PFS) and overall survival (OS) were compared using the log-rank test and Cox regression analysis based on original recurrence score (RS) categories (Low: 0-17, Intermediate: 18-30, High: 31-100) by treatment groups (A and B) and types of ABCs (recurrence and de novo stage IV).

Results: In total, 102 patients [Low: n = 44 (43.

Background/aim: Eribulin is an effective chemotherapeutic agent for advanced and metastatic breast cancer. However, severe neutropenia occurs in 30-40% of patients and interferes with the recommended treatment schedule. Neutropenia is a major cause of treatment interruptions, delays, or even relative dose reductions.

Background: Hormone receptor (HR)-positive breast cancer is a disease for which no immune checkpoint inhibitors have shown promise as effective therapies. Cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors synergistically increased the effectiveness of antiprogrammed cell death protein-1 (anti-PD-1)/programmed death-ligand 1 (PD-L1) antibodies in preclinical studies.

Methods: This non-randomized, multicohort, phase II study evaluated the efficacy and safety of the anti-PD-1 antibody nivolumab 240 mg administered every 2 weeks in combination with the CDK4/6 inhibitor abemaciclib 150 mg twice daily and either fulvestrant (FUL) or letrozole (LET) as a first-line or second-line treatment for HR-positive HER2-negative metastatic breast cancer.

Therapy for patients of metastatic breast cancer based on palbociclib, a cyclin-dependent kinase 4/6 inhibitor, has been approved in Japan. However, the risk factors for palbociclib-induced severe neutropenia in Japanese patients are rarely reported. Hence, the present study is aimed to identify the risk factors for adverse events requiring palbociclib dose reduction or discontinuation, and to identify the factors necessary to identify a more stable strategy for treatment continuation.

Article Synopsis
  • A study analyzed how dose reduction of abemaciclib affects treatment adherence in Japanese patients with advanced breast cancer (ABC) over a period from December 2018 to March 2021, involving 120 patients.
  • Results showed that patients on lower doses (100 mg and 200 mg per day) had significantly longer time to treatment failure (TTF) compared to those on the higher dose (300 mg per day), with median TTF of 17.9 months and 17.3 months respectively, as opposed to 7.4 months for the higher dose group.
  • Adverse effects like anemia and diarrhea were common and led to dose reductions, and the study concluded that lower doses significantly improved TTF, marking

Background: The efficacy of pre-operative systemic treatment (PST) combined with immune checkpoint inhibition (ICI) for triple-negative breast cancer (TNBC) has been recognized recently as being independent of the degree of programmed death ligand-1 (PD-L1) positivity of infiltrating immune cells, especially for patients with axillary lymph node metastasis (ALNM).

Methods: TNBC patients with ALNM were treated surgically between 2002 and 2016 in our facility (n = 109), of whom 38 received PST before resection. The presence of tumor-infiltrating lymphocytes (TILs) expressing CD3, CD8, CD68, PD-L1 (detected by antibody SP142) and FOXP3 at primary and metastatic LN sites was quantified.

Background: When considering BRCA1/2 genetic testing for diagnosis of hereditary breast and ovarian cancer (HBOC), family history (FH) of breast and ovarian cancer is commonly considered. However, FH of other HBOC-related cancers, such as prostate, pancreatic, and skin cancer (malignant melanoma), is often overlooked.

Methods: Among 945 patients who received genetic testing of BRCA1/2 at our hospital between October 2010 and September 2021, we compared the FH of 123 patients diagnosed with HBOC and 669 other patients who had breast cancer and had a documented FH.

Background: Eribulin therapy has recently attracted attention from various viewpoints, including quality of life, and is considered a standard therapy for inoperable or recurrent breast cancer. Although a reduction in renal function reportedly decreases total eribulin clearance, its association with dose-limiting toxicity and the reduction of neutrophils remain unclear.

Aim: This study was aimed at analyzing the association between decreased renal function prior to eribulin administration and the occurrence of neutrophil reduction and time to treatment failure in patients with breast cancer.

The value of assessing tumor infiltrating lymphocytes (TILs) in estrogen receptor (ER) positive/human epidermal growth factor receptor type 2 (HER2) negative breast cancer has yet to be determined. In the present study, a total of 184 cases with early distant recurrence detected within 5 years following the primary operation, 134 with late distant recurrence diagnosed following 5 years or longer and 321 controls without recurrence for >10 years following starting the initial treatment for ER-positive/HER2 negative breast cancer, registered in 9 institutions, were analyzed. The distributions of TILs and their clinical relevance were investigated.

Background: The status of tumor-infiltrating lymphocytes (TILs) is a prognostic factor for triple negative breast cancer (TNBC). Recent studies have shown that programmed cell death 1 (PD-1) or programmed death ligand 1 (PD-L1) is expressed on T lymphocytes or tumor cells modulating antitumor immunity. The regulation of immune checkpoints between tumor cells and T lymphocytes may serve as a target for improvement of TNBC prognosis.

Background: Most studies analyzing prognostic factors for late relapse have been performed in postmenopausal women who received tamoxifen or aromatase inhibitors as adjuvant endocrine therapy for estrogen receptor (ER)-positive breast cancer.

Methods: A total of 223 patients (108 premenopausal and 115 postmenopausal) with early distant recurrence and 149 patients (62 premenopausal and 87 postmenopausal) with late distant recurrence of ER-positive, HER2-negative breast cancer who were given their initial treatment between 2000 and 2004 were registered from nine institutions. For each late recurrence patient, approximately two matched control patients without relapse for more than 10 years were selected.

Background: The significance of the expression of aldehyde dehydrogenase 1 (ALDH1), a cancer stem cell marker, for predicting the recurrence of estrogen receptor (ER)-positive/human epidermal growth factor receptor type 2 (HER2)-negative breast cancer is still poorly understood. The value of ALDH1 in predicting the time of recurrence remains unknown.

Methods: In total, 184 patients with early distant recurrence, 134 patients with late distant recurrence, and 321 control patients without recurrence for more than 10 years after starting initial treatment for ER-positive/HER2-negative breast cancer, registered in 9 institutions, were analyzed.

Article Synopsis
  • The study utilized two-color fluorescence in situ hybridization to analyze chromosome numbers and genetic events in 177 neuroblastoma tumors, identifying them as either Dis1 or Tris1 groups based on chromosome 1 alterations.
  • Dis1 tumors exhibited a higher frequency of genetic events such as 17q gain, 1p deletion, and MYCN amplification compared to Tris1 tumors, suggesting Tris1 tumors have a resistance to these genetic changes.
  • The research indicates that the ploidy state of neuroblastomas influences their behavior and progression, with both groups potentially involving similar tumor-suppressor genes or oncogenes, regardless of risk level.
