ABSTRACT

OBJECTIVE: Neoadjuvant chemotherapy (NAC) is essential for surgical downstaging of early-stage breast cancer, but taxane administration is associated with neuropathy. We investigated whether eribulin induces less neuropathy than paclitaxel. METHODS: In this multicentre, randomised study (UMIN000012817), patients diagnosed with invasive breast cancer between December 2013 and April 2016 were randomly assigned to group E (eribulin followed by fluorouracil, epirubicin, and cyclophosphamide; FEC) or group P (paclitaxel followed by FEC). The primary endpoint was incidence of grade 1 or higher peripheral neuropathy according to the Common Terminology Criteria for Adverse Events (CTCAE). Secondary endpoints were pathological complete response (pCR), clinical response, breast-conserving surgery, adverse events, disease-free survival (DFS), and patient neurotoxicity questionnaire (PNQ) analysis. RESULTS: One hundred and eighteen cases were analyzed for safety and 115 were evaluated for efficacy. Peripheral sensory neuropathy was significantly lower in group E after week 6, while peripheral motor neuropathy in group E was significantly lower at weeks 9, 12, and 15. pCR in groups E and P was 20.7% and 29.8% (P = .289), respectively, and clinical response was 55.2% and 77.2% (P = .017), respectively. Three-year DFS was 89.7% in group E and 86.0% in group P (P = .561). Neutropenia was more frequent and more severe in group E. PNQ was evaluated for 4 years, and item 1 (sensory) was consistently lower in group E. CONCLUSION: Neuropathy was significantly less frequent and less severe in patients who received eribulin compared with paclitaxel. Thus, eribulin could be a good alternative to paclitaxel in patients suffering severe neuropathy.

ABSTRACT

INTRODUCTION: ß-ray strontium-89 (Sr-89) intra-irradiation therapy has been approved and clinically used to reduce bone metastasis pain not alleviated by bone-modifying agents, external radiation, and analgesic agents. We examined the efficacy of zoledronic acid (ZOL) and Sr-89 combination therapy compared with ZOL alone in breast cancer patients with bone metastases. MATERIALS AND METHODS: A randomized controlled trial was conducted on breast cancer patients with bone metastasis to compare the efficacy between ZOL monotherapy and ZOL plus Sr-89 combination therapy. The primary endpoints were changes in urinary NTX levels at 13 weeks and brief pain inventory scores. The secondary endpoints were analgesic drug usages, response rates, changes in bone metabolism markers, quality of life, and adverse event rates. RESULTS: Thirty of the planned 60 cases were randomly assigned to ZOL alone or ZOL + Sr-89. There were no significant differences in the changes in urinary NTX levels between the 2 groups (P = 0.365). There was no consistent difference in the pain score changes between the 2 groups. Sr-89 addition to ZOL slightly reduced the white blood cell and platelet counts. However, all adverse events were Grade 1. Safety and analgesic drug dose reduction were more evident in ZOL + Sr-89. CONCLUSION: This trial showed the lack of benefits from Sr-89 addition to ZOL for breast cancer patients with painful bone metastases. However, safety and analgesic drug dose reduction were more evident in ZOL + Sr-89, indicating its potential for pain control. Sr-89 therapy is safe, thus more effective radiopharmaceuticals are anticipated.

ABSTRACT

BACKGROUND: Osteoporosis is a major side effect of aromatase inhibitors (AIs), which are greatly effective in the treatment of breast cancer. However, there are no satisfactory measures against osteoporosis. In this multicenter, randomized, comparative study, we evaluate the efficacy of denosumab for preventing loss of bone mineral density (BMD) induced by adjuvant therapy with AI s in breast cancer patients with normal BMD. PATIENTS AND METHODS: The bone loss-suppressing effect of denosumab will be comparatively evaluated in postmenopausal patients scheduled to receive letrozole or anastrozole as a postoperative endocrine therapy for stage I-IIIA hormone-sensitive breast cancer and a control group. Patients will be administered letrozole 2.5 mg or anastrozole 1 mg once a day, and the treatment will be continued for 5 years unless recurrence, secondary cancer, or unacceptable toxicity develops. Patients in the denosumab group will receive a subcutaneous injection of 60 mg of denosumab every 6 months. The primary endpoint is the rate of change in the lumbar spine (L1-L4) BMD, as determined by dual-energy X-ray absorptiometry (DXA), 12 months after the start of the injection. The secondary endpoints were ETHICS AND DISSEMINATION:: The protocol was approved by the institutional review boards of Kyoto Prefectural University of Medicine and all the participating faculties. Written informed consent was obtained from all patients before registration, in accordance with the Declaration of Helsinki. Results of the study will be disseminated via publications in peer-reviewed journals. TRIAL REGISTRATION: Clinical Trials.gov Identifier: NCT03324932, Japan Registry of Clinical Trial (jRCT): CRB5180001.

ABSTRACT

BACKGROUND/AIM: Risk factors for chemotherapy-induced nausea and vomiting (CINV) with anthracycline-containing regimen for breast cancer patients remain unknown. The risk factors for CINV with FEC100 were investigated. PATIENTS AND METHODS: Data on CINV events and patient backgrounds of 180 patients were collected from the first cycle of FEC100 treatment. In this regimen, patients were administered various antiemetics (ADs). The combinations of ADs were classified into four categories, while body mass index (BMI) was stratified into three categories. Risk factors were selected based on patient characteristics and combination of ADs. Risks for CINV were analyzed by univariate and multivariate analyses. RESULTS: In the univariate analysis of nausea, BMI was a significant factor, while BMI and combination of ADs were significant in vomiting. In the multivariate analysis concerning nausea, BMI was a significant factor. In the analysis concerning vomiting, the combination of ADs and BMI were significant. CONCLUSION: BMI was the most important risk factor for nausea and vomiting, while the combination of ADs was for vomiting.

ABSTRACT

BACKGROUND: Aromatase inhibitors (AI) have been established as the gold-standard therapy for postmenopausal patients. Worldwide, adjuvant denosumab at a dose of 60 mg twice per year reduces the risk of clinical fractures in postmenopausal patients with breast cancer who received AI. However, the efficacy of denosumab in the treatment of AI-associated bone loss had not been prospectively evaluated in Japan. Previously, we reported the 12-month effect of denosumab in Japanese patients for the first time; the primary endpoint was the change in the percentage of bone mineral density (BMD) of the lumbar spine from baseline to 12 months. METHODS: This secondary follow-up study prospectively evaluated the change in the percentage of BMD of the lumbar spine from baseline to 24 months. Postmenopausal women with early-stage, histologically confirmed, hormone receptor-positive, invasive breast cancer who were receiving or scheduled to receive AI were included. Denosumab was administered subcutaneously on day 1 of the study and then 6, 12, 18, and 24 months. The lumbar spine and bilateral femoral neck BMD was measured at baseline and 6, 12, 18, and 24 months. RESULTS: At 18 and 24 months, the lumbar spine BMD increased by 5.9 and 7.0%, respectively. The femoral neck BMD also increased. Grade ≥ 2 hypocalcemia, osteonecrosis of the jaw, and atypical femoral fractures did not occur. CONCLUSIONS: Our prospective study showed that semiannual treatment with denosumab was associated with continuously increased BMD in Japanese women receiving adjuvant AI therapy for up to 24 months, regardless of prior AI treatment.

ABSTRACT

BACKGROUND: Nodular lesions of the thyroid gland, including papillary thyroid carcinoma (PTC), may be difficult to diagnose by imaging, such as in ultrasonic echo testing, or by needle biopsy. Definitive diagnosis is made by pathological examination but takes several days. A more rapid and simple method to clarify whether thyroid nodular lesions are benign or malignant is needed. Fluorescence imaging with γ-glutamyl hydroxymethyl rhodamine green (gGlu-HMRG) uses γ-glutamyltranspeptidase (GGT), a cell-surface enzyme, to hydrolyze the γ-glutamyl peptide and transfer the γ-glutamyl group. GGT is overexpressed in several cancers, such as breast, lung, and liver cancers. This imaging method is rapid and useful for detecting such cancers. In this study, we tried to develop a rapid fluorescence detection method for clinical samples of thyroid cancer, especially papillary carcinoma. METHODS: Fluorescence imaging with gGlu-HMRG was performed to detect PTC using 23 surgically resected clinical samples. A portable imaging device conveniently captured white-light images and fluorescence images with blue excitation light. Hematoxylin-eosin (HE) staining was used to evaluate which fluorescent regions coincided with cancer, and immunohistochemical examination was used to detect GGT expression. RESULTS: All 16 PTC samples exhibited fluorescence after topical application of gGlu-HMRG, whereas the normal sections of each sample showed no fluorescence. HE staining revealed that each fluorescent region corresponded to a region with carcinoma. The PTC samples also exhibited GGT expression, as confirmed by immunohistochemistry. CONCLUSIONS: All PTC samples were detected by fluorescence imaging with gGlu-HMRG. Thus, fluorescence imaging with gGlu-HMRG is a rapid, simple, and powerful detection tool for PTC.

ABSTRACT

BACKGROUND: Diagnostic imaging is important for predicting the pathological response to chemotherapy during neoadjuvant chemotherapy (NAC) and for considering the surgical management with appropriate resection after NAC. This study was performed to examine the accuracy of the present radiological imaging for predicting the pathological complete response (pCR). METHODS: From 188 patients in our previous JONIE1 Study, a randomized controlled trial comparing chemotherapy with and without zoledronic acid for patients with human epidermal growth factor receptor 2-negative breast cancer, we evaluated 122 patients whose tumor size was examined by magnetic resonance imaging or ultrasound at three points: before NAC; after administering fluorouracil, epirubicin, and cyclophosphamide; and after NAC. The maximum tumor diameter was evaluated by magnetic resonance imaging or ultrasound. Tumor reduction ratios were calculated at the same three points. The association between the radiological clinical response and the pCR was examined. RESULTS: Among the 122 patients evaluated, there were 98 and 24 patients with luminal (Lum) and triple-negative (TN) subtypes, respectively. There were no patients who showed tumor progression after treatment. The radiological size of the tumors was finally reduced by an average of 58.4%. Clinical complete response and pCR were achieved in 22 (18.0%) and 15 (12.3%) patients, respectively. In the overall population (n = 122), the accuracy, sensitivity, and specificity for predicting pCR were 86.1%, 88.8%, and 66.7%, respectively. The negative predictive value and false-negative rate were 45.5% and 11.2%, respectively. According to subtypes, the accuracies were 83.7% and 95.8% in Lum and TN, respectively. Negative predictive value and false-negative rate were markedly different between the Lum (29.4% and 13.5%) and TN subtypes (100% and 0%), respectively. CONCLUSIONS: This randomized clinical trial demonstrated that NAC was safe for operable breast cancer patients with appropriate radiological monitoring. Radiological evaluation after NAC may be a reliable method for predicting pathological response in the TN subtype, but not in the Lum subtype.

ABSTRACT

Because human epidermal growth factor-like receptor (HER) 2 is expressed on the surface of human pancreatic carcinoma cells to varying degrees, trastuzumab, an anti-HER2 monoclonal antibody (mAb), is expected to exert antibody-dependent, natural killer (NK) cell-mediated cytotoxicity (ADCC) against the cells. However, some reports found that the effect of trastuzumab against human pancreatic carcinoma cells was limited because most express only limited HER2. We examined whether anti-CD137 stimulating mAb could enhance trastuzumab-mediated ADCC against Panc-1, a human pancreatic cancer cell line with low HER2 expression, in vitro. Supplementation of anti-CD137 mAb could improve trastuzumab-mediated ADCC against Panc-1 which was insufficient without this stimulating antibody. The ADCC differed in individual cells, and this was related to the expression of CD137 on the surface of NK cells after trastuzumab stimulation in association with the Fcγ-RIIIA polymorphism. NK cells with Fcγ-RIIIA-VV/VF showed high levels of ADCC against Panc-1, but those with Fcγ-RIIIA-FF did not show optimal ADCC. In addition, trastuzumab-mediated ADCC against the human pancreatic cancer cell line Capan-1 with high HER2 expression was generally high and not affected by the Fcγ-RIIIA polymorphism. These results demonstrated that in Fcγ-RIIIA-VV/VF-carrying healthy individuals, trastuzumab plus αCD137 mAb could induce effective ADCC against HER2-low-expressing pancreatic cancer cell lines, and that such an approach may result in similar findings in patients with pancreatic cancer.

ABSTRACT

BACKGROUND: A randomized phase 2 trial in women with HER2-negative breast cancer has shown that adding zoledronic acid (ZOL) to neoadjuvant chemotherapy (CT) has potential anticancer benefits in postmenopausal and triple-negative (TN) breast cancer patients. We report the data for the secondary end point of disease-free survival (DFS). METHODS: Patients were randomly assigned to receive CT or CT + ZOL (CT-Z). All patients received four cycles of FEC100 followed by 12 cycles of paclitaxel weekly. ZOL (4 mg) was administered 3-4 times weekly for 7 wk to the CT-Z group patients. The primary end point was pathologic complete response (pCR). The secondary end points were the clinical response rates, rate of breast-conserving surgery, safety, and DFS. RESULTS: Of the 188 patients enrolled, 95 were assigned to the CT group and 93 to the CT-Z group. DFS and overall survival were analyzed in 92 and 88 patients with the mean times of 5.15 y and 5.38 y, respectively. The 3-y DFS rate was 84.6% in the CT group and 90.8% in the CT-Z group (P = 0.188). The particular benefit from ZOL for the neoadjuvant CT seen as improvement of the pCR rate was indicated in the 3-y DFS period for TN cancer cases (CT versus CT-Z: 70.6% versus 94.1%) but not for postmenopausal cases. CONCLUSIONS: ZOL did not improve DFS when combined with CT. However, the improvement of the pCR rate translated to survival outcomes in TN breast cancer. The short-term application of ZOL may not be sufficient to improve the outcome in postmenopausal patients.

ABSTRACT

Pharmacological treatment of hypercalcemia is essential for patients with parathyroid carcinoma and intractable primary hyperparathyroidism (PHPT). Use of the calcimimetic cinacalcet hydrochloride (cinacalcet) is an option to treat such patients. We investigated the efficacy and safety of cinacalcet in Japanese patients with parathyroid carcinoma and intractable PHPT. Five Japanese patients with parathyroid carcinoma and two with intractable PHPT were enrolled in an open-label, single-arm study consisting of titration and maintenance phases. Cinacalcet doses were titrated until the albumin-corrected serum calcium concentration decreased to 10.0 mg/dL or less or until dose escalation was considered not necessary or feasible. Serum calcium concentration at the baseline was 12.1 ± 1.3 mg/dL (mean ± standard deviation; range 10.4-14.6 mg/dL) and decreased to 10.1 ± 1.6 mg/dL (range 8.6-13.3 mg/dL) at the end of the titration phase with cinacalcet at a dosage of up to 75 mg three times a day. At the end of the titration phase, at least a 1 mg/dL reduction in serum calcium concentration from the baseline was observed in five patients (three with carcinoma and two with PHPT), and it decreased to the normocalcemic range in five patients (three with carcinoma and two with PHPT). Common adverse events were nausea and vomiting. One patient discontinued participation in the study because of an adverse event, liver disorder. Cinacalcet effectively relieved hypercalcemia in 60% of the Japanese patients with parathyroid carcinoma and might be effective in those with intractable PHPT. The drug might be tolerable and safe at a dosage of at most 75 mg three times a day.

ABSTRACT

PURPOSE: Zoledronic acid (ZOL) is a nitrogen-containing bisphosphonate that induces osteoclast apoptosis and inhibits bone resorption by inhibiting the mevalonate pathway. Its benefit for the prevention of skeletal complications due to bone metastases has been established. However, the antitumor efficacy of ZOL, although suggested by multiple preclinical and clinical studies, has not yet been clinically proven. We performed the present randomized Phase 2 trial to investigate the antitumor effect of ZOL with chemotherapy (CT). METHODS: Asian patients with HER2-negative invasive breast cancer were randomly assigned to either the CT or CT+ZOL (CTZ) group. One hundred and eighty-eight patients were randomized to either the CT group (n = 95) or the CTZ group (n = 93) from March 2010 to April 2012, and 180 patients were assessed. All patients received four cycles of FEC100 (fluorouracil 500 mg/m2, epirubicin 100 mg/m2, and cyclophosphamide 500 mg/m2), followed by 12 cycles of paclitaxel at 80 mg/m2 weekly. ZOL (4 mg) was administered three to four times weekly for 7 weeks to the patients in the CTZ group. The primary endpoint was the pathological complete response (pCR) rate, which was defined as no invasive cancer in the breast tissue specimen. Safety was assessed in all patients who received at least one dose of the study drug. RESULTS: This randomized controlled trial indicated that the rates of pCR in CTZ group (14.8%) was doubled to CT group (7.7%), respectively (one-sided chi-square test, p = 0.068), though the additional efficacy of zoledronic acid was not demonstrated statistically. The pCR rate in postmenopausal patients was 18.4% and 5.1% in the CTZ and CT groups, respectively (one-sided Fisher's exact test, p = 0.071), and that in patients with triple-negative breast cancer was 35.3% and 11.8% in the CTZ and CT groups, respectively (one-sided Fisher's exact test, p = 0.112). Thus the addition of ZOL to neoadjuvant CT has potential anticancer benefits in postmenopausal patients and patients with triple-negative breast cancer. Further investigation is warranted.

ABSTRACT

There are few reports on parathyroid ultrasonography of multiple endocrine neoplasia type 1 (MEN1). This study investigated the ultrasonographic features of parathyroid glands in 10 patients with MEN1 who underwent preoperative neck ultrasonography and parathyroidectomy between 2006 and 2010 at Toranomon Hospital. We retrospectively analyzed clinical features, laboratory and ultrasonographic data, and pathological diagnosis. A total of 38 parathyroid glands were surgically removed (three to five glands from each patient). All removed parathyroids were pathologically diagnosed as hyperplasia. Seven cases (70.0 %) had adenomatous thyroid nodules. Twenty-five enlarged parathyroid glands (65.8 %) were detected by preoperative ultrasonography with a detection rate of 81.8 % (9/11) and 59.3 % (16/27) for patients without and with adenomatous nodules, respectively. Total parathyroid gland weight and potentially predictable total parathyroid volume by preoperative ultrasonography were significantly correlated with preoperative serum intact parathyroid hormone (iPTH) concentration (R = 0.97, P < 0.001 and R = 0.96, P < 0.001, respectively). The equation used for prediction of the total volume by ultrasonography was 15 × iPTH (pg/ml) - 1,000 and that for total weight was 20 × iPTH (pg/ml) - 1,400. Although adenomatous nodules often coexisted with MEN1 and made identification of enlarged parathyroid glands by ultrasonography difficult, the positive correlation between the predictable parathyroid volume by ultrasonography and serum iPTH suggests that their measurement is useful in the preoperative detection and localization of enlarged parathyroid glands in patients with MEN1. Furthermore, the presence of parathyroid glands that should be resected can be predicted before surgery using the equation proposed here.

ABSTRACT

INTRODUCTION: An important mechanism by which trastuzumab inhibits the growth of human epidermal growth factor receptor 2 (HER2)-positive breast cancer cells is the activation of a host tumor response via antibody-dependent cell-mediated cytotoxicity (ADCC). Although paclitaxel has a synergistic effect in combination with trastuzumab, whether ADCC is enhanced by paclitaxel is not known. In the present study we examined whether adding paclitaxel to trastuzumab enhances ADCC and also investigated the kinetics of effector cells in ADCC. MATERIALS AND METHODS: The subjects were 20 patients with HER2-positive breast cancer: 9 received the combination of trastuzumab (4 mg/kg as a loading dose and 2 mg/kg weekly) and paclitaxel (80 mg/m(2) weekly) and 19 received monotherapy with trastuzumab. In blood samples (mononuclear cells) obtained before and 10 minutes after administration of chemotherapy, ADCC and the number of effector cells, including natural killer (NK) cells, monocytes, and CD64+ cells, were compared in each case. The ADCC was analyzed with a (51)Cr releasing assay using the SK-BR-3 cell line, and the fractions of NK cells (both CD16+ [FcγRIII] and CD56+) and CD64+ (FcγRI) cells were analyzed with flow cytometry. RESULTS: The mean ADCC level increased 20% after trastuzumab monotherapy and 126% (p<0.05) after combination therapy with trastuzumab and paclitaxel. All 9 patients receiving combination therapy had increased ADCC levels. The number of NK cells increased 51% after trastuzumab monotherapy and 112% (p<0.05) after combination therapy. No significant changes were found in monocytes (39% increase) or CD64+ cells (53% increase) after trastuzumab monotherapy, but monocytes decreased 40% (p<0.05) and CD64+ cells decreased 24% after combination therapy. CONCLUSIONS: Adding paclitaxel to trastuzumab significantly enhances ADCC, with levels twice as great as with trastuzumab monotherapy, through a rapid recruitment of NK cells. This finding suggests that the combination of trastuzumab and paclitaxel has a stronger-than-expected synergistic effect in HER2-positive breast cancer.

ABSTRACT

BACKGROUND: This retrospective study aimed to determine whether adverse events are more common in docetaxel followed by cyclophosphamide (TC) as compared to the reverse infusion order (rTC). METHODS: A retrospective analysis was undertaken at a single institution for 92 consecutive cases treated with TC or rTC for stage I-III breast cancer in a neoadjuvant/adjuvant setting between December 2006 and June 2011. TC was administered during the first 2.5 years and rTC in the latter 2 years. RESULTS: Among the 92 cases, 50 were in the TC arm and 42 in the rTC arm. Fatigue (72.0 vs. 23.8%), edema (48.0 vs. 16.7%), peripheral neuropathy (66.0 vs. 14.3%), myalgia (48.0 vs. 9.5%) and stomatitis (48.0 vs. 16.7%) occurred significantly more often in cases receiving TC compared to rTC, respectively. CONCLUSION: Nonhematological toxicities are less common in cases receiving rTC in comparison to those receiving TC.

ABSTRACT

BACKGROUND: Hepatitis C virus (HCV) infection is one of the major causes of chronic liver disease, and more than 880,000 people are estimated to be infected with HCV in Japan. Little information is available on the outcomes of HCV during chemotherapy for solid tumors, and the impact of HCV infection on toxicity of chemotherapy is unknown. MATERIALS AND METHODS: We performed a retrospective survey of 1,110 patients diagnosed with breast cancer between January 2006 and March 2011 at our institution. All patients had been screened for hepatitis C serology at diagnosis of breast cancer. We retrospectively investigated the change in HCV load and the toxicities of chemotherapy, based on review of their medical records. RESULTS: 23 patients were identified as having a positive test for anti-HCV antibodies. Ten of these patients received chemotherapy. Their median age was 66 years. No patient had decompensated liver disease at baseline. Eight patients received cytotoxic agents with or without trastuzumab, and two patients received trastuzumab alone. Four of eight patients who received cytotoxic chemotherapy developed febrile neutropenia and one developed transaminases elevation. Serum HCV-ribonucleic acid (RNA) level before and after chemotherapy was evaluated in six patients. Median serum HCV-RNA level at baseline and after chemotherapy was 6.5 and 6.7 logIU/ml, respectively. CONCLUSION: Chemotherapy for breast cancer patients with HCV infection is feasible, and viral load doesn't change during the chemotherapy.

ABSTRACT

OBJECTIVE: The aims of the present study were as follows: (i) to clarify the proportion of women who experience psychological distress during breast cancer diagnosis and (ii) to identify the predictors of psychological distress related to the diagnostic process. METHODS: This was a longitudinal prospective study of women who required further breast examination. Questionnaires were administered at pre-medical consultations (Time 1), after describing radiological examination (Time 2), and after explaining pathological findings (Time 3). All participants completed Hospital Anxiety and Depression Scale (HADS), Functional Assessment of Cancer Therapy--Breast, and Functional Assessment of Chronic Illness Therapy--Spiritual subscale at Time 1 to identify predictors. Participants also completed HADS at Times 2 and 3 to identify the presence or absence of psychological distress. RESULTS: Of the 222 eligible patients, at Time 2, 31 (22.6%) participants with no clinical abnormalities and 39 (45.9%) participants with abnormal findings had HADS scores of ≥ 11 points (χ2 test, 13.14; p < 0.001). At Time 3, 14 (28.0%) participants with benign breast changes and 24 (68.6%) participants with breast cancer had scores of ≥ 11 (χ2 test, 13.71; p < 0.001). Higher HADS scores at Time 1 were associated with the presence of psychological distress at all stages of breast cancer diagnosis. Advanced tumor stage was a predictor of psychological distress for participants with breast cancer (odds ratios = 3.314, 95% confidence interval = 1.033-9.509; p = 0.044). CONCLUSION: These results suggest that intensive psychological intervention is necessary for breast cancer patients with large tumors, as well as for women with suspected breast cancer with high HADS scores at pre-consultation.

ABSTRACT

A 62-year-old woman presented with a mass on the left side of the neck. Biochemical testing revealed primary hyperparathyroidism. Further, a prolactinoma was detected, and the patient's son and daughter also had primary hyperparathyroidism, indicating that the patient had multiple endocrine neoplasia type 1 (MEN1). Neck ultrasonography revealed several cystic nodules (≤ 30 mm) that appeared to be adenomatous. After parathyroidectomy with autotransplantation, the largest cystic mass, in the left lower thyroid lobe, was pathologically diagnosed as a functioning parathyroid cyst, and all laboratory data returned to normal. On genetic analysis of blood, we found a novel single base insertion (duplication) in exon 10 codon 552 of the MEN1 gene (c1659dupT) that creates an early stop codon. This is the first case report of a parathyroid cyst resulting from parathyroid hyperplasia in a MEN1 patient.

ABSTRACT

Nodular fasciitis of the breast is a rare, benign, soft-tissue tumor that can clinically and radiologically mimic invasive ductal carcinoma. A 25-year-old woman presented with a palpable lesion in the lower inner aspect of the left breast. Radiologically, breast carcinoma could not be excluded. On examination of the core needle biopsy, the tumor was characterized histologically as a spindle cell tumor. Excisional biopsy was performed. The tumor was diagnosed as nodular fasciitis of the breast. The imaging and histological findings of this case are presented.

ABSTRACT

The morbidity and mortality of individuals with multiple endocrine neoplasia type 1 (MEN1) can be reduced by early diagnosis of MEN1 and related endocrine tumors. To find factors contributing to early diagnosis, we collected clinical information on MEN1 patients through a MEN study group, "MEN Consortium of Japan" and analyzed the time of initial symptom-dependent detection of parathyroid tumors, gastro-entero-pancreatic neuroendocrine tumors (GEPNETs) and pituitary tumors, and that of tumor detection-dependent MEN1 diagnosis in 560 patients. Main tumors were identified up to 7.0 years after symptoms appeared and there was no difference in age at the diagnosis of GEPNETs alone between probands and family members. In patients with typical symptoms (peptic ulcers, urolithiasis, fasting hypoglycemia, bone fracture/loss and amenorrhea), the mean interval between symptom manifestation and tumor detection was extended up to 9.6 years. In particular, 21.7% (5/23) of patients with amenorrhea were diagnosed with pituitary tumors in under one year. In patients with peptic ulcers (from parathyroid tumors or GEPNETs) and urolithiasis (from parathyroid tumors), the interval was positively correlated with age at tumor detection. The interval between tumor detection and MEN1 diagnosis was also prolonged to approximately four years in patients with fasting hypoglycemia (from GEPNETs) and amenorrhea. A substantial delay in the diagnosis of symptom-related tumors and subsequent MEN1 and inadequate screening of GEPNETs in family members were indicated. A greater understanding of MEN1 may assist medical practitioners to make earlier diagnoses, to share patients' medical information and to give family members sufficient disease information.
