We present the surgical outcome of 81 patients with chest wall perforator flaps used for breast-conserving surgery. Methods: We recorded the outcomes of three oncoplastic breast surgeons who performed partial breast reconstruction with chest wall perforator flaps from 1<sup>st</sup> January 2018 to 30<sup>th</sup> June 2022 at Sherwood Forest Hospitals NHS Foundation Trust. Data were collected on patient demographics, including age, BMI, smoking status, bra size, previous treatments, type of CWPF procedure, tumor size (measured clinically, via imaging and histologically), biopsy results, specimen weight, margins involvement, re-operation rate, surgical site infection (SSI), flap loss, flap shrinkage, hematoma, and seroma rates. Results: A total of 81 patients were included in this study, with an average age of 55.7 years and a body mass index (BMI) of 26.7 kg/m<sup>2</sup>. The bra size varied between A to FF with A (7.4%), B (28.3%), C (38.2%), D (13.6%), DD (11.1%), and FF (1.2%). 14.8% of the patients had neoadjuvant chemotherapy (NACT). For 45 patients, LICAP (lateral intercostal artery perforator), 16 AICAP (anterior intercostal artery perforator), 13 MICAP (medial intercostal artery perforator), and for seven patients, LTAP (lateral thoracic artery perforator) flaps were used. The average tumor was measured at 15.75 mm clinically, 19.1 mm via imaging, and 19.6 mm histologically. Biopsy showed that 16% of the tumors were ductal carcinoma in situ (DCIS), and 84% were invasive. 16% of patients had involved margins, and re-excision was required in 10 patients, and completion mastectomy was performed in 2 patients. A thirty-day SSI rate was 6.2%, with flap-related complications, including flap loss and shrinkage, at 3.7% and 4.9%, respectively. In addition, 3.7% had a hematoma, and 17.3% had other complications. Conclusion: Partial breast reconstruction with perforator flaps is an excellent volume replacement technique in breast-conserving surgery with acceptable complications in well-selected cases.展开更多

Methods:...Introduction: The aim of the study was to compare the feasibility and safety of endoscopic thyroid lobectomy via axillary-breast-shoulder approach (ET via ABS) with a conventional open thyroid lobectomy (OT). Methods: From November 2014 to December 2015, 20 patients with unilateral benign thyroid nodules were treated with ET via ABS and another 20 patients were treated with an OT. We analyzed the clinical characteristics postoperative complications, pain, and patient satisfaction. Results: No statistically significant differences occurred between groups except the mean ages of the OT group and the ET via ABS group were 55 and 44 years, respectively (p = 0.015). The mean operative time was almost the same in both groups (116 min in the OT group and 114 min in the ET via ABS group). Blood loss was significantly higher in the OT group than in the ET via ABS group (p = 0.042) but postoperative drainage was detected more in the ET via ABS group (p p = 0.026). The hospital stay was three days in OT group and four days in ET via ABS group (p = 0.909). Postoperative complications such as hematoma, hoarseness, dysphagia, and prolonged subcutaneous emphysema were detected only in the ET via ABS group but without statistical difference. More patients were “very satisfied” with the treatment in the ET via ABS group than in the OT group. Conclusion: The ET via ABS is as safe and effective as the OT for patients with unilateral thyroid nodules. With less early postoperative pain and higher patient satisfaction, this endoscopic thyroidectomy approach should be considered in patients who concern about cosmetic results.展开更多

Papillary carcinomas of the chest wall are always secondary to thyroid, thymus and ovaries. Other variants of breast cancer metastasizing to the chest wall have been reported. CASE: We report a 67-year-old woman presented to us with an ulcerated anterior chest wall mass of 1-year duration, bilateral axillary, supraclavicular and cervical swellings of 8-month duration. There was a history of breast lump which was noticed 5 years prior to presentation, no history of breast malignancy in the past and no family history of breast cancer. Examination revealed an ulcerated, nodular mass over the sternal angle which measured 14 cm × 12 cm × 4 cm;she had bilateral axillary, supraclavicular and cervical lymphadenopathy which were non-tender and matted. She had a firm, non-tender right breast lump measuring 6 cm × 4 cm. Chest examination and abdominal examinations were essentially normal. Chest X-ray revealed erosion of sternal bone without any evidence of intrathoracic extension. Abdominal ultrasound and thyroid scans were normal. Histology of the mass revealed papillary carcinoma. Biopsy of the right breast also revealed papillary carcinoma. She had excision of the fungating tumour and primary closure of defect. She subsequently had combination chemotherapy using ondasetron, cyclophosphamide, adriamycin and cisplantin. CONCLUSION: Papillary carcinoma of the breast is rare and rarely metastasizes to the chest wall. The diagnosis of metastatic chest wall tumour requires meticulous history taking, clinical examination and relevant investigations to ascertain the primary origin of the carcinoma.展开更多

The care of the breast cancer patient requires in many centres. The care of breast cancer patient is undertaken as a joint venture between the surgeon, medical oncologist, radiotherapist, pathologist and allied health professionals such as the clinical nurse specialist as well as counsellors. This is a case of a 39-years-old Malay woman presented to HUSM with a history of ulcerating breast lump with bloody pus discharge on the right breast. An initial mammogram study showed lesion suspicious of malignancy, and histopathological examination was consistent with invasive ductal carcinoma. She received neoadjuvant chemotherapy before proceeding to right modified radical mastectomy with axillary clearance and immediate chest wall reconstruction. Detailed discussion on the diagnosis, treatment, surgical intervention and progress of the patient with reference to available literature reviews are presented.展开更多

We performed a resection of the first and second ribs and a reconstruction of the chest wall. A thoracotomy was performed at the anterolateral second intercostal space. The second rib cartilage was divided at the left parasternum. Based on a transmanubrial osteomuscular sparing approach, the left-upper part of the sternum and the first rib cartilage were both cut at the left clavicular-sternum joint. The posterior parts of the two ribs involving the tumor were resected at the transverse process of the vertebral bone by tearing off the anterior, middle, and posterior scalene muscles, subclavicular artery and vein. The defect size of the thorax was 15 × 9 cm, which was reconstructed by covering with a polytetrafluoroethylene dual mesh (Dual mesh, Gore tex, 2 mm). The major pectoral muscle flap was used to cover the mesh. The postoperative pathological examination diagnosed a poorly differentiated fibrosarcoma. Eventually, she had palliative therapy for the postoperative metastatic chest wall. She died 14 months after the operation.展开更多

Early detection and accurate diagnosis of this disease has been demonstrated an approach to long survival of the patients. As an attempt to develop a reliable diagnosing method for breast cancer, we integrated support vector machine (SVM), k-nearest neighbor and probabilistic neural network into a complex machine learning approach to detect malignant breast tumour through a set of indicators consisting of age and ten cellular features of fine-needle aspiration of breast which were ranked according to signal-to-noise ratio to identify determinants distinguishing benign breast tumours from malignant ones. The method turned out to significantly improve the diagnosis, with a sensitivity of 94.04%, a specificity of 97.37%, and an overall accuracy up to 96.24% when SVM was adopted with the sigmoid kernel function under 5-fold cross validation. The results suggest that SVM is a promising methodology to be further developed into a practical adjunct implement to help discerning benign and malignant breast tumours and thus reduce the incidence of misdiagnosis.展开更多
