Patient Preference for Surgical Methods for Ipsilateral Breast Tumor Recurrence.

BACKGROUND: Mastectomy has been the standard surgical treatment for ipsilateral breast tumor recurrence (IBTR). Recently, there has been growing interest in repeat breast-conserving surgery (rBCS) for IBTR among breast surgeons; however, there is currently little information regarding patient preferences for surgical procedure for IBTR. The purpose of this study was to evaluate preference for surgical procedure (mastectomy vs. rBCS) among breast cancer patients who had undergone salvage surgery for IBTR. METHODS: Overall, 100 breast cancer patients who had undergone salvage surgery for IBTR were asked about their preferred surgical methods for IBTR and the reason. The association of patient preference and the reasons related to various clinical and pathological factors were assessed. RESULTS: Of the 100 respondents, only 11 patients (11%) preferred rBCS. Patients who had undergone rBCS and radiotherapy for IBTR were significantly more likely to prefer to undergo rBCS than other groups (p = 0.030). The most frequent reason for choosing rBCS was the patient's desire to minimize breast deformity and surgical wounds. CONCLUSIONS: Our study revealed that there is a low rate of patients who opt to undergo rBCS among patients who had undergone salvage surgery for IBTR. Discrepancies in perceptions regarding the surgical procedure for IBTR between patients and their surgeons may exist.

Long-Term Outcomes of Breast Cancer Patients with Local Recurrence After Mastectomy Undergoing Immediate Breast Reconstruction: A Retrospective Multi-institutional Study of 4153 Cases.

BACKGROUND: The number of breast cancer patients in Japan undergoing immediate breast reconstruction (IBR) has increased and the postoperative follow-up period has been extended. This study was conducted to clarify the clinical aspects of, and factors associated with, local recurrence (LR) after IBR. METHODS: This was a multicenter study which included 4153 early breast cancer patients who underwent IBR. Clinicopathological characteristics were examined and factors potentially contributing to LR were analyzed. Risk factors for LR were examined separately for non-invasive and invasive breast cancers. RESULTS: The median follow-up period was 75 months. The 7-year LR rates were 2.1% and 4.3% for non-invasive and invasive cancers, respectively (p < 0.001). The proportions of LR detected by palpation, subjective symptoms, and ultrasonography were 40.0%, 27.3%, and 25.9%, respectively. Overall, 75.7% of LR were solitary, and 92.7% of these cases had no further recurrences during the observational period. Multivariate analysis of LR for invasive cancer showed that skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM), the presence of lymphovascular invasion, cancer at the surgical margin, and not receiving radiation therapy were factors related to LR. The 7-year overall survival rates of the patients with LR and non-LR of invasive cancers were 92.5% and 97.3%, respectively, (p = 0.002). CONCLUSIONS: The rate of LR after IBR was acceptably low and IBR can thus be performed safely for early breast cancer patients. Invasive cancer, SSM/NSM, lymphovascular invasion, and/or cancer at the surgical margin should prompt awareness of the possibility of LR.

Classification of Local Recurrence After Nipple-Sparing Mastectomy Based on Location: The Features of Nipple-Areolar Recurrence Differ from Those of Other Local Recurrences.

BACKGROUND: Little information is available about the clinical and pathologic characteristics of local recurrence (LR) after nipple-sparing mastectomy according to the locations of LR. METHODS: This study classified 99 patients into the following two groups according to the location of LR after nipple-sparing mastectomy: nipple-areolar recurrence (NAR) group and other locations of LR (oLR) group. The study evaluated whether the location of LR was associated with disease-free survival (DFS) after LR resection. RESULTS: For about half of the patients (44.4 %) with NAR, the primary cancer was estrogen receptor (ER)-negative and human epidermal growth factor receptor 2 (HER2)-positive. Conversely, in most of the patients with oLR (79.2 %), the primary cancer was ER-positive and HER2-negative. Among the LR tumors, the frequency of noninvasive carcinoma in the NAR tumors was significantly higher than in the oLR tumors (51.9 % vs 4.2 %, respectively). During a median follow-up period of 46 months, the location of LR was not associated with DFS after LR. In the NAR group, the presence or absence of LR tumor invasiveness was the only factor associated with DFS. In the oLR group, age at primary surgery was the only factor associated with DFS. CONCLUSION: This multi-institutional retrospective study demonstrated that the features of NAR, such as the characteristics of the primary and recurrent tumors and the prognostic factors after LR resection, were quite different from those of oLR.

Long-term course of the changes in the nipple position after breast-conserving surgery.

PURPOSE: Even if favorable cosmetic outcomes are obtained shortly after breast-conserving surgery (BCS), cosmetic changes may occur up to several years after BCS. In the present study, we evaluated cosmetic changes while focusing on changes in the nipple position after BCS. METHODS: We examined the long-term course of changes in the nipple position over time after BCS using the proportion of the distance between the sternal notch and nipple (PDSN) in 196 patients. We also evaluated risk factors for long-term nipple position changes. RESULTS: The median follow-up period was 9.9 years. Nipple position changes occurred within eight years after BCS and seemed to plateau beyond that point. The body mass index (BMI), breast size, proportion of excision volume and axillary treatment were significantly associated with the nipple position changes within one to five years after BCS. The BMI, breast size, axillary treatment, chemotherapy and hormonal therapy were significantly associated with the nipple position changes within five to eight years after BCS. CONCLUSIONS: After BCS, the nipple position changes occur within about eight years. Obesity, large breast size, large excision volume, axillary treatment, chemotherapy and hormone therapy were factors that affected the treated breast shrinkage and increase in the left-right difference after BCS.

Prognosis and effectiveness of chemotherapy for medullary breast carcinoma.

PURPOSE: We aimed to determine the prognosis and potential benefit of postoperative chemotherapy according to subtype of medullary breast carcinoma (MedBC), a very rare invasive breast cancer. METHODS: A cohort of 1518 female patients with unilateral MedBC and 284,544 invasive ductal carcinoma (IDC) cases were enrolled from the Japanese Breast Cancer Registry. Prognosis of MedBC was compared to IDC among patients with estrogen receptor (ER)-negative and HER2-negative subtype (553 exact-matched patients) and ER-positive and HER2-negative subtype (163 MedBC and 489 IDC patients via Cox regression). Disease free-survival (DFS) and overall survival (OS) were compared between propensity score-matched adjuvant chemotherapy users and non-users with ER-negative and HER2-negative MedBC. RESULTS: Among ER-negative and HER2-negative subtype patients, DFS (hazard ratio (HR) 0.45; 95% confidence interval (95% CI), 0.30-0.68; log-rank P < 0.001) and OS (HR 0.51; 95% CI 0.32-0.83; log-rank P = 0.004) were significantly better in MedBC than IDC. Patients treated with postoperative chemotherapy showed better DFS (HR 0.27; 95% CI 0.09-0.80; log-rank P = 0.02) and OS (HR 0.27; 95% CI 0.09-0.80; log-rank P = 0.02) compared to those without. For the ER-positive and HER2-negative subtype, the point estimate for HR for DFS was 0.60 (95% CI 0.24-1.22) while that for OS was 0.98 (95% CI 0.46-1.84) for MedBC. CONCLUSION: In ER-negative and HER2-negative MedBC, the risk of recurrence and death was significantly lower than that of IDC, about half. Postoperative chemotherapy reduced recurrence and mortality. ER-positive and HER2-negative MedBC may have a lower risk of recurrence compared to IDC.

Risk Factors for Ipsilateral Breast Tumor Recurrence in Triple-Negative or HER2-Positive Breast Cancer Patients Who Achieve a Pathologic Complete Response After Neoadjuvant Chemotherapy.

BACKGROUND: Attention has been focused on attempts to eliminate breast surgery for breast cancer patients who achieve a pathologic complete response after neoadjuvant chemotherapy (NAC). However, there are few data on ipsilateral breast tumor recurrence (IBTR) among patients with triple-negative or epidermal growth factor receptor 2-positive (HER2+) tumors who achieve a pathologic complete response after NAC and breast-conserving treatment. METHODS: Using a multi-institutional retrospective database, this study evaluated the risk factors for IBTR among patients with newly diagnosed stages 1 to 3 breast cancer involving triple-negative or HER2+ tumors who achieved ypT0 after NAC and breast-conserving treatment. RESULTS: During a median follow-up period of 4.8 years (range, 0.1-15.5 years), the 5-year IBTR-free survival rate was 95.5%. The breast cancer subtype was not associated with IBTR-free survival. Patients younger than 40 years at diagnosis had significantly worse IBTR-free survival than those who were 40 years of age or older (5-year IBTR-free survival, 87.7 vs 96.9%; p = 0.002). CONCLUSIONS: This retrospective study demonstrated that age at diagnosis was independently associated with IBTR-free survival. Special caution is needed when clinical trials analyzing omission of breast surgery after NAC are enrolling younger patients (UMIN-CTR No. UMIN000037067).

Clinical features of bipolar disorder with idiopathic basal ganglia calcification: a review of case reports in the literature.

Although idiopathic basal ganglia calcification (IBGC) is associated with various neuropsychiatric disturbances including several cases of bipolar disorder (BD), there has been no systematic review of clinical features of patients with BD and comorbid IBGC. We undertook a literature search to identify case reports of these patients. Most cases showed complex syndromes comprising not only mood disturbance but also cognitive disability and motor symptoms limited to depressive state and had favorable treatment response. These patients should have a careful and repeated psychiatric, neurological, and cognitive assessment to determine an optimal diagnostic and treatment approaches at each clinical stage.

Risk factors for locoregional disease recurrence after breast-conserving therapy in patients with breast cancer treated with neoadjuvant chemotherapy: An international collaboration and individual patient meta-analysis.

BACKGROUND: Several studies have reported a high risk of local disease recurrence (LR) and locoregional disease recurrence (LRR) in patients with breast cancer after neoadjuvant chemotherapy (NCT) and breast-conserving therapy (BCT). The objective of the current study was to identify potential risk factors for LR and LRR after NCT and BCT. METHODS: Individual patient data sets from 9 studies were pooled. The outcomes of interest were the occurrence of LR and/or LRR. A 1-stage meta-analytic approach was used. Cox proportional hazards regression models were applied to identify factors that were predictive of LR and LRR, respectively. RESULTS: A total of 9 studies (4125 patients) provided their data sets. The 10-year LR rate was 6.5%, whereas the 10-year LRR rate was 10.3%. Four factors were found to be associated with a higher risk of LR: 1) estrogen receptor-negative disease; 2) cN + disease; 3) a lack of pathologic complete response in axilla (pN0); and 4) pN2 to pN3 disease. The predictive score for LR determined 3 risk groups: a low-risk, intermediate-risk, and high-risk group with 10-year LR rates of 4.0%, 7.9%, and 20.4%, respectively. Two additional factors were found to be associated with an increased risk of LRR: cT3 to cT4 disease and a lack of pathologic complete response in the breast. The predictive score for LRR determined 3 risk groups; a low-risk, intermediate-risk, and high-risk group with 10-year LRR rates of 3.2%, 10.1%, and 24.1%, respectively. CONCLUSIONS: BCT after NCT appears to be an oncologically safe procedure for a large percentage of patients with breast cancer. Two easy-to-use clinical scores were developed that can help clinicians to identify patients at higher risk of LR and LRR after NCT and BCT and individualize the postoperative treatment plan and follow-up.

pTis and pT1a Ipsilateral Breast Tumor Recurrence Is Associated with Good Prognosis after Salvage Surgery.

OBJECTIVES: Patients with ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery have a poor prognosis. There is little information regarding the prognostic impact of the tumor size in patients with IBTR. METHODS: A total of 143 patients who had histologically confirmed IBTR without distant metastases and who underwent salvage surgery between 1989 and 2013 in our hospital were included. Distant disease-free survival (DDFS) was calculated according to the invasive tumor size of IBTR. The median follow-up period was 4.6 years. RESULTS: Patients with pT1b or more advanced IBTR have a high (≥20%) 5-year distant recurrence risk. There were significant differences in DDFS between patients with pTis or pT1a and those with pT1b or a more advanced stage (5-year DDFS: 94.4 vs. 70.1%, respectively, p value = 0.006). This significance remained after adjusting for other clinicopathological factors (p value = 0.04). CONCLUSION: Patients with pTis or pT1a IBTR have a good prognosis after salvage surgery for IBTR, and the omission of adjuvant chemotherapy could be considered. Further research and validation studies are needed.

A prospective feasibility study applying the ACOSOG Z0011 criteria to Japanese patients with early breast cancer undergoing breast-conserving surgery.

BACKGROUND: In patients undergoing breast-conserving surgery and having positive sentinel lymph nodes (SLNs), the ACOSOG Z0011 trial showed equivalent loco-regional outcomes for patients receiving SLN dissection (SLND) alone and those receiving axillary lymph node dissection (ALND). We conducted a prospective single-arm study to confirm the applicability of the Z0011 criteria to Japanese patients with breast cancer. METHODS: Patients meeting the Z0011 inclusion criteria and providing consent to receive no additional ALND were prospectively enrolled at the Osaka International Cancer Institute from April 2012 to December 2016. Cumulative incidence of loco-regional recurrence was estimated and compared to that of the Z0011 study. RESULTS: Among a total of 881 patients who underwent breast-conserving surgery, 189 fulfilling the Z0011 criteria were enrolled and eligible for the subsequent analysis. Adjuvant chemotherapy was given to 113 (59.8%) patients, adjuvant hormone therapy to 170 (89.9%), and whole breast irradiation to 183 (96.8%). The frequency of tumors with positive lymphovascular invasion (p < 0.0001) and macrometastases in SLNs (p < 0.0001) were significantly higher in our study than in the Z0011 study. At the median follow-up of 36 months (range 10-64 months), only 2 of 189 patients (1.1%) experienced loco-regional recurrence. The 5-year cumulative rate of loco-regional recurrences was 1.3% (95% CI 0-3.1%), and the 3-year distant DFS rate was 96.8% (95% CI 94.0-99.6%). CONCLUSIONS: Our prospective study showed that it is feasible to apply the Z0011 strategy to Japanese patients with clinically node-negative breast cancer undergoing breast-conserving surgery with planned whole breast irradiation.

Current viewpoints on DSM-5 in Japan.

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) was published in 2013, and its official Japanese version was published in 2014. The Japanese Government uses classifications from the 10th revision of the I nternational C lassification of D iseases (ICD-10) to categorize disorders and determine treatment fees. However, since the publication of the DSM-III, the use of the DSM system has become prevalent in research and educational settings in Japan. In addition to traditional psychiatry, both the ICD and the DSM are taught by many Japanese medical schools, and virtually all clinical research and trials refer to the DSM to define targeted disorders. Amid the current backdrop in which the reputation of the DSM-5 is being established, the editorial board of P sychiatry and C linical N eurosciences has asked Japanese experts across 12 specialties to examine the structure of the DSM-5, including the following categories: Neurodevelopmental Disorders, Schizophrenia Spectrum Disorders, Major Depression, Bipolar Disorders, Obsessive-Compulsive Disorders, Somatic Symptom Disorder, Eating Disorders, Substance-Related and Addictive Disorders, Gender Dysphoria, and Neurocognitive Disorders. Although opinions were only obtained from these selected experts, we believe that we have succeeded, to a certain extent, in presenting views that are representative of each specialty.

Distant Recurrence Risk after Late Ipsilateral Breast Tumor Recurrence: Results of a Retrospective, Single-Institution Study.

OBJECTIVES: There is limited information regarding risk factors for distant recurrence in patients with late ipsilateral breast tumor recurrence (IBTR). METHODS: Late IBTR was defined as IBTR occurring >5 years after the initial surgery. Seventy-eight patients with late IBTR were reviewed to examine the risk factors of distant recurrence. RESULTS: The negative estrogen receptor and positive HER2 statuses of IBTR were significantly correlated with poorer distant disease-free survival (p=0.03 and 0.02, respectively). Multivariate analyses demonstrated that the HER2 status of IBTR was an independent predictive factor of distant recurrence (p=0.04). CONCLUSIONS: The results of our retrospective, single-institution study revealed that the HER2 status of IBTR was an independent predictive factor of distant recurrence in patients with late IBTR.

Regional lymphatic recurrence after salvage surgery for ipsilateral breast tumor recurrence of breast cancer without local treatment for regional lymphatic basin.

BACKGROUND: There is limited information regarding rates of and risk factors for regional lymphatic recurrence (RLR) after salvage surgery for ipsilateral breast tumor recurrence (IBTR) without local treatment for the regional lymphatic basin. METHODS: One hundred two patients, who underwent salvage breast surgery without local treatment for the regional lymphatic basin (surgery or radiotherapy) for IBTR that relapsed after breast-conserving surgery for primary breast cancer, were reviewed retrospectively to examine the rate of and risk factors for RLR. RESULTS: Of the 102 patients, 9 patients (8.8%) had RLR with a median follow-up period of 3.7 years after salvage breast surgery for IBTR. The estrogen receptor (ER) status and lymphovascular invasion of the recurrent breast tumor were both independent predictive factors of RLR (P = 0.04 and 0.02, respectively). CONCLUSIONS: The rate of RLR was not low in patients with IBTR who received salvage breast surgery only without any treatment for the regional lymphatic basin. The ER status and lymphovascular invasion of the recurrent breast tumor were predictive factors of RLR.

Mirtazapine Monotherapy for Antipsychotics-refractory Psychosis in a Patient with Very-late-onset Schizophrenia-like Psychosis: A Case Report.

Very-late-onset schizophrenia-like psychosis (VLOSLP) is a condition in which psychotic symptoms emerge after the age of 60 years. Given its heterogeneous nature, VLOSLP remains a diagnostic and therapeutic dilemma. Here, we report a case of a 68-year-old patient with psychosis refractory to antipsychotics who was successfully treated with mirtazapine monotherapy. This case suggests that mirtazapine monotherapy may be effective for the treatment of patients with antipsychotic- refractory VLOSLP.
