Background
Owing to low incidence rates, population-based breast cancer screening is not recommended by many municipalities in Japan for women aged < 40 years. To evaluate the usefulness of screening ...in women aged < 40 years, we investigated the results of population-based breast cancer screening among young women performed in the Ibaraki Prefecture.
Methods
Data regarding histological characteristics, recall rates, cancer detection rates, positive predictive values, tumor categories, and status of lymph node metastases were obtained from population-based screening data from Ibaraki Health Service Association Institute. The “number needing to be screened” (NNS) was determined; using Pearson’s chi-squared test, these data were compared between women aged < 40 years and > 40 years.
Results
The data of 428,560 women were evaluated. Cancer detection rates were significantly lower and the NNS and proportion of women with tumor category T2 or higher was significantly increased in women aged < 40 years than in those aged > 40 years (0.06% vs. 0.21%, 1505 vs. 281–439, and 28.9% vs. 6.3%, respectively; all,
p
< 0.05). The proportion of early-stage cancers was lower in women aged < 40 years than in those > 40 years, but this was not significant.
Conclusions
These results suggest that population-based breast cancer screening should not be recommended for women aged < 40 years. To reduce the breast cancer-related mortality rate in young women and ensure efficient use of limited medical resources in Japan, a more efficient surveillance system, based on genetic propensity and family history, needs to be established.
The complete blood cell count is one of the most frequently ordered laboratory tests, and many parameters, including red blood cell distribution width (RDW) and mean platelet volume (MPV), are ...available. The purpose of this study was to investigate the usefulness of the combination of RDW and MPV in patients with ST-segment elevation myocardial infarction (STEMI). Patients with STEMI who underwent primary percutaneous coronary intervention were retrospectively enrolled (
n
= 229). The association between RDW as well as MPV and cardiovascular events was investigated. The median age was 67 years, and males made up 85% of the sample. Median RDW was 13.6%, and median MPV was 8.2 fL. During a median follow-up period of 528 days (IQR 331.5–920.5), 41 patients died or experienced major adverse cardiac and cerebrovascular events (MACCEs). Patients with RDW ≧ 13.7% had more deaths or MACCEs with marginal significance (
p
= 0.0799). Patients with MPV ≧ 8.3 fL had significantly more deaths or MACCEs (
p
= 0.0283). Patients with RDW ≧ 13.7% and MPV ≧ 8.3 fL had significantly more deaths or MACCEs (
p
= 0.0185). MPV was significantly associated with death or adverse events in patients with STEMI who were treated with primary PCI. RDW had only a weak association with death or adverse events. The results of the combination of MPV and RDW were similar to those of MPV.
BackgroundChemotherapy-induced peripheral neuropathy (CIPN) is a problematic adverse event for breast cancer patients receiving taxane antimitotic agents. We evaluated the effectiveness of ...compression therapy against CIPN in the lower extremities of breast cancer patients receiving taxanes.MethodsEligible patients scheduled for perioperative treatment with taxanes for early-stage breast cancer were enrolled. Each patient wore latex-free surgical gloves and compression socks, putting on two layers of each 15 minutes before the administration of taxanes and removing them 15 minutes after administration. Peripheral neuropathy (PN) was evaluated using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 and the Patient Neurotoxicity Questionnaire (PNQ). The primary endpoint was the incidence of CTCAE version 4.0 grade 2 or higher CIPN in the lower extremities during the entire period of perioperative chemotherapy with taxanes.ResultsPN assessment by CTCAE in the lower extremities, the primary outcome, showed that 13.3% developed grade 2 sensory disturbances, and 8.3% developed grade 2 motor disturbances. The incidence of CTCAE grade 2 or higher PN in the hands was 26.7% for sensory disturbances and 13.3% for motor disturbances during the entire study period. No patient had grade 3 or higher PN. No adverse events due to compression therapy were observed.ConclusionCompression of the lower extremities with compression socks tended to reduce the incidence of CIPN compared to the general incidence. Compression therapy may help prevent the development of CIPN.
As an oncologic emergency related to abnormalities in calcium metabolism, hypercalcemia associated with paraneoplastic syndrome and bone metastases is well known. Meanwhile, the incidence of ...hypocalcemia is low, except in cases associated with bone-modifying agents used for bone metastases. Hypocalcemia induced by bone-modifying agents typically occurs early after the initial administration, and its incidence can be significantly reduced by preventive administration of calcium and vitamin D3 supplements.
We report two cases of recurrent severe hypocalcemia occurring during chemotherapy for metastatic breast cancer with multiple bone metastases. Case 1: A 35-year-old Japanese woman developed metastases in the bone, liver, and ovaries during postoperative endocrine therapy for invasive lobular carcinoma of the breast. She underwent chemotherapy and treatment with denosumab. She experienced recurrent episodes of severe hypocalcemia subsequent to a change in the chemotherapy regimen. Case 2: A 65-year-old Japanese woman encountered multiple bone metastases after postoperative anti-human epidermal growth factor receptor 2 therapy and during endocrine therapy for invasive ductal carcinoma of the breast. She underwent anti-human epidermal growth factor receptor 2 therapy and treatment with denosumab. She experienced recurrent severe hypocalcemia subsequent to a change in the chemotherapy regimen to letrozole + lapatinib, trastuzumab emtansine, and lapatinib + capecitabine.
We observed two cases of recurrent severe hypocalcemia in patients with advanced breast cancer and bone metastases after modifications to their therapy regimens. These cases differed from the typical hypocalcemia induced by bone-modifying agents. It is possible that antitumor drugs affect calcium and bone metabolism associated with bone metastases. While these cases are rare, it is crucial for oncologists to be aware of hypocalcemia not only at the initiation of bone-modifying agents but also throughout the entire antitumor therapy, as hypocalcemia can lead to fatal outcomes.
While the prognosis for ductal carcinoma in situ (DCIS) of the breast is generally excellent, distant metastasis after appropriate local treatment is extremely rare. We experienced two cases of ...distant metastasis after mastectomy for breast ductal carcinoma in situ. In both cases, the surgical margins were negative, the sentinel nodes were negative for metastasis. The first case was a 67-year-old woman who developed lung metastases four years after mastectomy for high-grade DCIS. The second case was a 34-year-old woman with intermediate-grade DCIS who developed intraductal recurrence localized to the nipple two years after the initial nipple-sparing mastectomy and multiple lung and liver metastases six months later. Both cases developed distant metastases despite appropriate local treatment, without preceding or concurrent invasive local recurrence. Although the probability of distant recurrence is low, it is important to inform patients about the risk of recurrence.
Seeding of cancer cells along the needle tract during core needle biopsy is a well-known phenomenon, with a reported frequency of between 22 and 50% Hoorntje et al. in Eur J Surg Oncol 30:520–525, ...2004;Liebens et al. in Maturitas 62:113–123, 2009;Diaz et al. in AJR Am J Roentgenol 173:1303–1313, 1999;. Local recurrence due to needle tract seeding is rare because the immune system eliminates the cancer cells in most cases. In addition, most local recurrences due to needle tract seeding occur as invasive carcinoma after diagnosis of invasive ductal carcinoma of the breast or mucinous carcinoma, and needle tract seeding due to noninvasive carcinoma is uncommon. We herein report a rare case of local breast cancer recurrence histologically resembling Paget disease, presumably due to needle tract seeding after core needle biopsy for diagnosis of ductal carcinoma in situ of the breast.
After receiving a diagnosis of ductal carcinoma in situ, the patient underwent skin-sparing mastectomy and breast reconstruction with a latissimus dorsi musculocutaneous flap. The pathological study showed ER/PgR-negative ductal carcinoma in situ, and no postoperative radiation therapy or systemic therapy was administered. Six months after the surgery, the patient had a breast cancer recurrence histologically resembling Paget disease, presumably in the scar of her core needle biopsy. The pathological study showed Paget disease localized in the epidermis, no invasive carcinoma, and no lymph node metastasis. It was morphologically similar to the primary lesion and was diagnosed as a local recurrence due to needle tract seeding.
Background/Aims: Intestinal Behçet disease is typically associated with ileocecal punched-out ulcers and significant morbidity and mortality. Intestinal ultrasound is a noninvasive imaging technique ...for disease monitoring. However, no previous reports have compared intestinal ultrasound with endoscopic ulcer activity or histopathological findings for intestinal Behçet disease. We evaluated the usefulness of intestinal ultrasound for assessing the activity of ileocecal ulcers in intestinal Behçet disease.Methods: We retrospectively compared intestinal ultrasound findings with 73 corresponding endoscopic images and 6 resected specimens. The intestinal ultrasound findings were assessed for 7 parameters (bowel wall thickness, vascularity evaluated using the modified Limberg score with color Doppler, bowel wall stratification, white-plaque sign strong hyperechogenic lines or spots, mesenteric lymphadenopathy, extramural phlegmons, and fistulas), and endoscopic ulcer activity was classified into active, healing, and scar stages. Histopathological findings were evaluated by consensus among experienced pathologists. Results: Bowel wall thickness (P<0.001), vascularity (P<0.001), loss of bowel wall stratification (P=0.015), and white-plague sign (P=0.013) were significantly exacerbated in the endoscopic active ulcer stage. Receiver operating characteristic curve analysis revealed that a bowel wall thickness of > 5.5 mm (sensitivity 89.7%, specificity 85.3%) was potentially useful for detecting active lesions. When compared with histopathological findings, an increase in bowel wall thickness reflected the ulcer marginal ridge, and the white-plaque sign reflected the ulcer bottom. Conclusions: Intestinal ultrasound is useful for monitoring intestinal ulcer activity in intestinal Behçet disease.
Cancer-associated thrombosis is known as Trousseau syndrome (TS). Here, we report 4 cases of TS associated with advanced breast cancer that caused central nervous system (CNS) vascular events. All 4 ...patients experienced sudden onset of CNS symptoms. Imaging revealed multiple brain infarctions or intracranial hemorrhage and all 4 patients had leptomeningeal or brain metastasis. Laboratory findings showed hypercoagulability at diagnosis of TS. Of the 4 patients, 2 patients were treated with unfractionated heparin, while 2 patients could not undergo anticoagulant therapy. In all patients, once the TS occurred, the CNS symptoms progressed rapidly and the prognosis was very poor, 3 patients dying within about a month of diagnosis of TS. Therefore, the predictive factors of TS are important and standards and guidelines for administration of anticoagulants are needed.
