ABSTRACT

We present the case of an 88-year-old woman who had undergone breast conserving surgery for left breast cancer 8 years ago.She received postoperative radiotherapy(total dose of 60 G/30 Fr)to the residual breast together with endocrine therapy.She underwent skin biopsy after having had a red skin tumor in the left breast.Angiosarcoma was diagnosed and chemotherapy and radiotherapy were initiated.The patient is alive without recurrence 8 months after chemotherapy.

ABSTRACT

A 46-year-old woman with metastatic breast cancer developed dyspnea that progressed relatively rapidly during chemotherapy. Chest-abdominal CT revealed wedge-shaped infiltration shadow, and cardiac catheterization revealed elevated pulmonary artery pressure. Aspiration cytology of pulmonary arterial blood was performed and malignant cells were confirmed. Chemotherapy was difficult to continue because of deterioration in general condition, and she died 7 days after diagnosis. This time, we report a case of PTTM for which pulmonary arterial blood cytology was useful for diagnosis.

ABSTRACT

BACKGROUND: Breast carcinoma and precancer are thought to start in the lining of the milk duct or lobule. Ductography and fiberoptic ductoscopy have beenadvocated as the mainprocedures inpatien ts with nipple discharge. METHODS: We investigated the usefulness of microdochectomy(MD)by using indocyanine green(ICG)fluorescence imaging. ICG and indigo carmine were injected into the mammary duct. A periareolar incision was made, and a fluorescence image of the demarcated mammary duct segment was obtained. CONCLUSION: MD using indocyanine green fluorescence imaging is a useful procedure in guiding subsequent breast surgery in the treatment of nipple discharge.

ABSTRACT

Nipple discharge is a common symptom and frequently results from benign tumors. However, there is a 5-30% risk of malignancy. A 65-year-old woman presented at the hospital because of bloody nipple discharge in her right breast. She had noticed an abnormal nipple discharge for several months. Mammography showed focal asymmetric densities without calcification in the middle outer quadrant of her right breast. Ultrasonography indicated a 1.5×1.1 cm sized cyst with fluid-fluid level. Breast MRI showed a simple cyst with a benign contrast enhancement pattern. No malignant cells were observed by fine-needle aspiration. Considering the low sensitivity of mammography and breast MRI to DCIS, we performed an excisional biopsy. Histological examination revealed that the lesion was DCIS. The patient underwent right total mastectomy and was diagnosed with low grade DCIS(ER-positive, PgR-positive, HER2-negative). She continues endocrine therapy with an aromatase inhibitor.

ABSTRACT

In case an operation is necessary after an ST-VAB for microcalcification, a wide excision needs to be performed because of the loss of marking. The HydroMARK®breast biopsy marker can be visualized using an ultrasound or mammography and facilitates a small excision. Six months after the deployment, all markers were visualized using an ultrasound. Thus, Hydro MARK®can decrease the sample size(11 g)in open biopsies and correctly diagnose ADH. However, no HydroMARK®cases were diagnosed with ADH in large samples(44 g, 32 g). Five malignant histology cases underwent mastectomy, and the distance between the HydroMARK®and tumor was 300 mm. HydroMARK®appears to be a safe and effective marker after a stereotactic biopsy for calcification, which facilitates an exact small excision of lesion surgically.

ABSTRACT

A69 -year-old woman was diagnosed as having local advanced breast cancer. She was treated with neoadjuvant chemotherapy( AC followed by paclitaxel)and followed up with left total mastectomy with axillary lymphadenectomy for breast cancer(pT3N1aM0, Stage ⅢA, ER positive, PgR positive, and HER2 negative). She received adjuvant therapy with chest wall irradiation and an aromatase inhibitor. Two years after the mastectomy, mediastinal lymph node and rib metastases and dissemination appeared. We changed the regimen to capecitabine. She continued the capecitabine therapy for 7 years and was found to have multiple lung metastasis. Therefore, we chose eribulin mesylate therapy. Ten days after eribulin mesylate (1.0mg/body)was first administered, she suddenly had difficulty breathing, and chest CT revealed left low lobe atelectasis. The superior mediastinal lymph node had grown rapidly and compressed the left main bronchus and superior vena cava. To reduce the lymph node size, we started radiotherapy(50 Gy/25 Fr)for the superior mediastinal area in addition to the eribulin mesylate therapy. After the radiotherapy, chest CT revealed a remarkable reduction of lymph node size and full pulmonary reexpansion. One year after the radiotherapy, she is continuing treatment without systemic progression.

ABSTRACT

Clinically, the incidence of postoperative nausea and vomiting (PONV) may be higher in mentally challenged patients than in normal healthy patients. The aim of this study was to investigate the risk factors for PONV after day care general anesthesia in mentally challenged patients undergoing dental treatment. We analyzed data on 231 day care general anesthesia cases involving mentally challenged patients undergoing dental treatment. Anesthetic records for the past 5 years were investigated retrospectively. Ten items (age, body weight, sex, duration of general anesthesia, use of propofol, use of sevoflurane, use of nitrous oxide, use of neostigmine, treatment accompanied with bleeding, and transfusion volume) were selected as risk factors for PONV. Postoperative nausea and vomiting was evaluated using the postoperative check sheet and linear discriminant analysis was performed to distinguish PONV incidence using the 10 items as independent variables. The reliability of the linear discriminant function was evaluated using a misjudgment rate and information criteria (AIC). Postoperative nausea and vomiting was observed in 13 cases out of 231 cases. The discriminant function with the smallest AIC (-25.0718) consisted of two independent variables: y=-0.077x(1)-0.001x(2)+0.0716(x(1)=use of propofol, x(2)=age). The misjudgment rate was 31.6%. This result suggests that PONV decreases when propofol is used and that the incidence of PONV decreases with age. To investigate other risk factors, an additional analysis was performed using 83 out of the 231 cases in which sevoflurane was used as an anesthetic agent. The results of the subgroup analysis suggest that the incidence of PONV decreases in male patients and higher weight patients, although the patient's body weight may be related to age, as the study cohort included many children. It is suggested that the major risks for PONV in mentally challenged patients after day care general anesthesia are no use of propofol, lower age, female sex and lower weight.
