Analysis of the distinct features of metastasis male breast cancer and its effect on overall survival based on the SEER database compared with female breast cancer.

Background: Male breast cancer (MBC) is a rare disease and differs from female breast cancer (FBC) in clinicopathological and immune tissue types. Given the limited research on MBC due to its rarity, an understanding of the shared and distinct features of MBC and FBC is vital for formulating efficacious treatment strategies. Methods: Data of patients diagnosed with metastatic breast cancer in the Surveillance, Epidemiology, and End Results (SEER) database from 2012 to 2017 were analysed. Chi-square test was used to compare clinicopathological characteristics between male and female patients. Kaplan-Meier analysis was utilized to compare differences in overall survival (OS). Results: A total of 2,858 patients with MBC were studied, 134 of whom had distant metastasis. Compared with 8,698 patients with metastatic FBC, a higher proportion of metastatic MBC patients had tumors located in the center of the breast, received surgical treatment, and had bone + lung metastasis. Survival analysis revealed no difference in OS between metastatic MBC and FBC patients (P=0.27), but there was a significant difference in OS between metastatic and nonmetastatic MBC (P=0.004). Compared with metastatic FBC, MBC patients with bone metastasis alone, lung metastasis alone, liver metastasis alone, and bone + lung metastasis also had worse prognosis (P=0.021, 0.019, 0.024, 0.011, respectively). Conclusions: Metastatic MBC has unique clinicopathological disease features and patterns of metastasis. No significant difference between the survival of metastatic MBC and FBC patients was observed. Distant metastasis was an independent risk factor impacting the prognosis of MBC patients.

Classification and assessment techniques of breast ptosis: A systematic review.

BACKGROUND: Breast ptosis is characterized by the inferolateral descent of the glandular area and nipple-areola complex. A high degree of ptosis may negatively impact a woman's attractiveness and self-confidence. There are various classifications and measurement techniques for breast ptosis used as references in the medical and garment industry. A practical and comprehensive classification will provide accurate standardized definitions of the degrees of ptosis to facilitate the development of corrective surgeries and well-fitting undergarments for women in need. METHODS: A systematic review on the classification and assessment techniques to measure breast ptosis was carried out based on the Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) guidelines. The risk of bias was assessed using the modified Newcastle-Ottawa scale for observational studies, whereas the Revised Cochrane risk-of-bias tool for randomized trials (RoB2) was used to evaluate randomized studies. RESULTS: Of 2550 articles identified in the literature search, 16 observational and 2 randomized studies describing the classification and assessment techniques of breast ptosis were included in the review. A total of 2033 subjects were involved. Half of the total observational studies had a Newcastle-Ottawa scale score of 5 and above. In addition, all randomized trials recorded a low overall bias. CONCLUSION: A total of 7 classifications and 4 measurement techniques for breast ptosis were identified. However, most studies did not demonstrate a clear derivation of sample size beside lacking robust statistical analysis. Hence, further studies that apply the latest technology to combine the strength of previous assessment techniques are needed to develop better classification system that is applicable to all affected women.

"An Unusual Pattern of Metastasis" Metastatic Malignant Thymoma Presented with Breast Lump: A Case Report and Literature Review.

Metastatic lesions to the breast from extramammary malignant neoplasms are rare and reported account for 0.5-6.6% of all breast malignancies. Distant metastasis of thymoma is even rarer, especially to extrathoracic regions. We reported a woman with invasive malignant thymoma postneoadjuvant and resection of the thymoma, who developed breast metastasis 7 years later. Breast imaging showed high-density lesion with no intralesional microcalcifications and no significant axillary lymphadenopathy. Core biopsy and histopathology proved the lesion to be metastatic thymic carcinoma. Despite rarity, breast lumps with underlying extramammary malignancy should raise the suspicious of breast metastasis.

Benefits of PECS Block as Part of the Enhanced Recovery After Surgery (ERAS) Protocol for Breast Cancer Surgery in an Asian Institution: A Retrospective Cohort Study.

INTRODUCTION: Regional analgesia techniques have been increasingly used for post-operative pain management following mastectomy. We aim to evaluate analgesic benefits of pectoral nerve (PECS2) block incorporated as part of the enhanced recovery after surgery (ERAS) protocol in patients undergoing mastectomy in University Malaya Medical Centre, Malaysia. MATERIAL AND METHODS: A single centre, cohort study evaluating 335 women who have undergone unilateral mastectomy between January 2017 and March 2020 in Malaysia. Regional anaesthesia were given pre-operatively via ultrasound guided pectoral and intercostal nerves block (PECSII). RESULTS: Utilization of regional anaesthesia increased from 11% in 2017 to 43% in 2020. Types and duration of surgeries were comparable. Opiod consumption was 3 mg lower in those who had PECS2 block ((27 [24-30] mg), in comparison with those who received general anaesthesia only (30 [26-34] mg), p < 0.001, and length of stay was half a day shorter in the regional anaesthesia group and these were statistically significant. However, pain score (2 [1-3]; 2 [1-3], p=0.719) and post-operative nausea and vomiting (PONV) (32.6-32.5%, p = 0.996) were similar. CONCLUSION: This study highlights the importance of PECS2 block as a component of ERAS protocol for mastectomy in an Asian hospital. This study also inferred that patients may be safely discharged within 24 h of surgery and therefore, same day surgery may be feasible in selected group of patients undergoing mastectomy and this could imply overall cost benefits.

Comparison of Clinical Outcomes Between Low- and High-Risk Groups of Early Breast Cancer Patients Treated with Intraoperative Radiotherapy in Addition to External Beam Radiation: A Multi-Centre Prospective Study.

BACKGROUND: There is a paucity of data on the use of intraoperative radiotherapy (IORT) with low-energy X-rays in Malaysian women with early breast cancer. The aim of this study is to evaluate the clinical, cosmetic, and patient-reported outcomes in low- and high-risk early breast cancer patients treated with breast conserving surgery (BCS) and IORT. METHODOLOGY: Patients suitable for BCS who were treated with IORT between January 2016 and June 2019 from three centres were analysed. They were divided into low-risk and high-risk groups based on the risk of recurrence according to the TARGeted Intraoperative radioTherapy (TARGIT) A and B study criteria. Outcomes of interest included local recurrence, wound complications, and radiation toxicity, with a subset analysed for cosmetic and patient-reported outcomes. RESULTS: Within a median follow-up of 31 months, there were 104 and 211 patients in the low- and high-risk groups, respectively. No significant difference was observed in local recurrence rates (low-risk, 1.0% vs. high-risk, 1.4%; p = 1.000). Both cohorts exhibited low frequencies of severe wound complications ranging between 1.4 and 1.9%. No major radiation toxicities were reported in either group. In the subgroup analysis, low-risk patients had significantly better mean scores in the subscales of inframammary fold and scar. Based on the BREAST-Q patient-reported outcomes questionnaire, seven out of nine parameters were scored similarly between both groups with no significant difference. CONCLUSION: This study showed that the use of IORT in both low- and high-risk early breast cancers is efficacious and safe with low recurrence rates and an acceptable toxicity profile.

Mindful gratitude journaling: psychological distress, quality of life and suffering in advanced cancer: a randomised controlled trial.

CONTEXT: Numerous studies have shown that gratitude can reduce stress and improve quality of life. OBJECTIVE: Our study aimed to examine the effect of mindful gratitude journaling on suffering, psychological distress and quality of life of patients with advanced cancer. METHODS: We conducted a parallel-group, blinded, randomised controlled trial at the University of Malaya Medical Centre, Malaysia. Ninety-two adult patients with advanced cancer, and an overall suffering score ≥4/10 based on the Suffering Pictogram were recruited and randomly assigned to either a mindful gratitude journaling group (N=49) or a routine journaling group (N=43). RESULTS: After 1 week, there were significant reductions in the overall suffering score from the baseline in both the intervention group (mean difference in overall suffering score=-2.0, 95% CI=-2.7 to -1.4, t=-6.125, p=0.000) and the control group (mean difference in overall suffering score=-1.6, 95% CI=-2.3 to -0.8, t=-4.106, p=0.037). There were also significant improvements in the total Hospital Anxiety and Depression Scale score (mean difference=-3.4, 95% CI=-5.3 to -1.5, t=-3.525, p=0.000) and the total Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being score (mean difference=7.3, 95% CI=1.5 to 13.1, t=2.460, p=0.014) in the intervention group after 7 days, but not in the control group. CONCLUSION: The results provide evidence that 7 days of mindful gratitude journaling could positively affect the state of suffering, psychological distress and quality of life of patients with advanced cancer. TRIAL REGISTRATION NUMBER: The trial was registered with the Australian and New Zealand Clinical Trials Registry (ACTRN1261800172191) and conducted in accordance with the Declaration of Helsinki.

A rare case of persistent large cystic breast tumor mimicking as malignant cystic breast cancer.

Breast cyst, especially galactocele is usually benign. Needle aspiration or surgical removal are both diagnostic and therapeutic. Mastectomy is not necessary even if the whole breast is affected, but surgeons need to be vigilant. We describe a rare case of persistent and large breast cyst.

Outcomes after mastectomy with immediate breast reconstruction for breast cancer in a multiethnic, middle-income Asian setting.

BACKGROUND: Although immediate breast reconstruction is increasingly becoming popular worldwide, evidence from resource-limited settings is scarce. We investigated factors associated with immediate breast reconstruction in a multiethnic, middle-income Asian setting. Short-term surgical complications, timing of initiation of chemotherapy, and survival outcomes were compared between women undergoing mastectomy alone and their counterparts receiving immediate breast reconstruction. METHODS: This historical cohort study included women who underwent mastectomy after diagnosis with stage 0 to stage IIIa breast cancer from 2011 to 2015 in a tertiary hospital. Multivariable regression analyses were used to assess factors associated with immediate breast reconstruction and to measure clinical outcomes. RESULT: Out of 790 patients with early breast cancer who had undergone mastectomy, only 68 (8.6%) received immediate breast reconstruction. Immediate breast reconstruction was independently associated with younger age at diagnosis, recent calendar years, Chinese ethnicity, higher education level, and invasive ductal carcinomas. Although immediate breast reconstruction was associated with a higher risk of short-term local surgical complications (adjusted odds ratio: 3.58 [95% confidence interval 1.75-7.30]), there were no significant differences in terms of delay in initiation of chemotherapy, 5-year disease-free survival, and 5-year overall survival between both groups in the multivariable analyses. CONCLUSION: Although associated with short-term surgical complications, immediate breast reconstruction after mastectomy does not appear to be associated with delays in initiation of chemotherapy, recurrence, or mortality after breast cancer. These findings are valuable in facilitating shared surgical decision-making, improving access to immediate breast reconstruction, and setting priorities for surgical trainings in middle-income settings.

Desmoid Type Fibromatosis of the Breast Masquerading as Breast Carcinoma: Value of Dynamic Magnetic Resonance Imaging and Its Correlation.

Desmoid type fibromatosis of the breast is a rare stromal tumor that accounts for <0.2% of all breast tumors. Bilateral and multicentric lesions are extremely rare, with only less than ten cases reported in the literature. Although benign, it is locally aggressive with frequent recurrence in up to almost one-third of the cases. We experienced our first case of bilateral multicentric breast fibromatosis in a 19-year-old woman, with a paternal aunt diagnosed with breast cancer at age 30, who presented to our institution with the chief complaint of retracted nipples for 1 year. The patient denied any history of trauma to her chest. Sonography showed suspicious bilateral hypoechoic masses. Magnetic resonance imaging (MRI) was performed for further evaluation because of the extensive involvement of both the breasts. This report aimed to illustrate the main clinical, radiological, and histopathological characteristics of this rare disease to increase awareness of this entity and discuss the role of MRI.

Outcomes of Asian Women Treated With Grisotti Flap Reconstruction for Centrally Located Breast Cancers: 5-Years Single Institutional Experience.

INTRODUCTION: Breast conserving surgeries were previously contraindicated for central breast cancers because of poor cosmetic outcomes of central mastectomy without oncoplastic surgery. Grisotti flap is a breast-conserving surgery incorporating oncoplastic surgery technique for centrally located breast cancers. We present our experience and outcome from Breast Surgery Unit, University Malaya Medical Center. MATERIALS AND METHODS: A prospective analysis of 15 patients with central retroareolar breast cancer operated from 2012 to 2018 in University Malaya Medical Center. We assessed postoperative complications, margins, locoregional recurrence, and survival outcome. All patients received postoperative radiotherapy. Patients were followed-up 1 week, 1 month, 3 monthly for 1 year and 6 monthly for 5 years. RESULTS: Mean age of patients is 62 years. Mean follow-up is 51 months (15-84 months). All tumors were less than 5 cm (1-2.5 cm). Majority of the patients are stage 1 (6 patients/40%) and stage 2 (8 patients/ 53.3%). 2 patients had surgical site infection resolved with antibiotics. One patient had hematoma. None require reoperation. Tumor margins were clear in all patients. No locoregional recurrence. Overall survival is 100%. All are satisfied with their cosmetic outcomes. CONCLUSIONS: Grisotti flap is a volume displacement technique, which provides satisfactory cosmetic outcome for centrally located breast cancer. This evolutionary thinking leads us to changes in existing techniques with the purpose of achieving oncological safety while reaching for better esthetic results. Our 5 years' experience in Asian population showed that this technique is oncologically safe with good cosmetic outcomes and could be used selectively. It provides a good alternative in patients who are otherwise subjected for mastectomy. This relatively simple technique is a worthwhile endeavor and should be offered when feasible.

A case series of intestinal obstruction secondary to shiitake mushroom intake during Chinese New Year.

Shiitake mushroom is a common ingredient in East Asian cuisines. Food processing/preparation can cause the mushroom to be soft and slimy, leading to accidental swallowing. Due to its high insoluble fibre content, it remains the same size and shape in the intestinal tract. We present two cases of small bowel obstruction caused by shiitake mushroom requiring surgical intervention. Preoperative imaging showed dilated small bowel with a suspicious mass in the ileum. However, the exact cause was unclear. For both cases, exploratory laparotomy and enterotomy were then performed and undigested shiitake mushroom was found. Both patients recovered well from the surgery.

Oncological safety and postoperative complications in oncoplastic breast surgery among Asian women: A single institutional review.

Oncoplastic breast surgery (OBS) improves margin clearance and produces good esthetic outcome in breast cancer treatment. This study evaluates the complications and outcome of OBS in a multiracial patient cohort. Data of 421 patients between 2011 and 2018 were analyzed. The majority were Malays (41.8%), followed by Chinese (39.7%) and Indians (16.8%). Low local complications were noted, with no significant differences in disease-free survival (P = .927) and overall survival (P = .719) between low and high OBS levels. Shared decision-making in offering OBS for Asian women has potential to become a practical option in breast cancer treatment.

Gastrointestinal tract metastasis presenting as intussusception in invasive lobular carcinoma of the breast: A case report.

INTRODUCTION: Breast cancer metastasis to the gastrointestinal (GI) tract is rare and occurs more frequently in invasive lobular carcinoma. Patients may be asymptomatic or present with variable vague symptoms that may be mistakenly attributed to side effects of chemotherapy or other benign GI diseases. Treatment follows the principles of systemic disease and includes hormonal therapy, chemotherapy and signal transduction inhibitors, with surgical intervention indicated for complications such as obstruction, perforation and hemorrhage. PRESENTATION OF CASE: We present the case of a female patient with a history of invasive lobular breast carcinoma who had undergone mastectomy and axillary dissection, followed by chemoradiotherapy. Over the next nine years, she developed ovarian and bone metastases for which appropriate treatment was provided. A right iliac fossa mass was discovered during routine clinic review, though she remained asymptomatic. Computed tomography scan showed ileocecal intussusception. Histopathological examination of the right hemicolectomy specimen following emergency surgery confirmed metastatic invasive lobular carcinoma to the GI tract. DISCUSSION: GI tract metastasis may present 30 years after the primary breast cancer. Up to 20% of patients may be asymptomatic as shown by Montagna et al. When present, symptoms are commonly non-specific and vague. Histological diagnosis is challenging. GI metastasis typically appears as intramural infiltration of the bowel wall by small cells arranged in cords. CONCLUSION: It is important to maintain a suspicion for GI tract metastasis in breast cancer patients who present with abdominal mass or GI symptoms, as this aids in prompt institution of accurate and appropriate management.
