Obesity and male breast cancer: Provocative parallels?

While rare compared to female breast cancer the incidence of male breast cancer (MBC) has increased in the last few decades. Without comprehensive epidemiological studies, the explanation for the increased incidence of MBC can only be speculated. Nevertheless, one of the most worrying global public health issues is the exponential rise in the number of overweight and obese people, especially in the developed world. Although obesity is not considered an established risk factor for MBC, studies have shown increased incidence among obese individuals. With this observation in mind, this article highlights the correlation between the increased incidence of MBC and the current trends in obesity as a growing problem in the 21st century, including how this may impact treatment. With MBC becoming more prominent we put forward the notion that, not only is obesity a risk factor for MBC, but that increasing obesity trends are a contributing factor to its increased incidence

A rare case of small bowel volvulus after jenjunoileal bariatric bypass requiring emergency surgery: a case report

<p>Abstract</p> <p>Introduction</p> <p>Bariatric surgery is on the increase throughout the world. Jejunoileal bypass bariatric procedures have fallen out of favor in western surgical centers due to the high rate of associated complications. They are, however, performed routinely in other centers and as a consequence of health tourism, management of complications related to these procedures may still be encountered.</p> <p>Case presentation</p> <p>We describe a rare case of small bowel obstruction in a 45-year-old British Caucasian woman, secondary to a volvulus of the jejunoileal anastomosis following bariatric bypass surgery. The pre-operative diagnosis was confirmed by radiology. We describe a successful surgical technique for this rare complication.</p> <p>Conclusions</p> <p>Bariatric surgery may be complicated by bowel obstruction. Early imaging is vital for diagnosis and effective management. The use of our surgical technique provides a simple and effective approach for the successful management of this bariatric complication.</p

Sternalis muscle: an underestimated anterior chest wall anatomical variant

Over the recent years, an increased alertness for thorough knowledge of anatomical variants with clinical significance has been recorded in order to minimize the risks of surgical complications. We report a rare case of bilateral strap-like sternalis muscle of the anterior chest wall in a female cadaver. Its presence may evoke alterations in the electrocardiogram or confuse a routine mammography. The incidental finding of a sternalis muscle in mammography, CT, and MRI studies must be documented in a patient's medical records as it can be used as a pedicle flap or flap microvascular anastomosis during reconstructive surgery of the anterior chest wall, head and neck, and breast. Moreover, its presence may be misdiagnosed as a wide range of benign and malignant anterior chest wall lesions and tumors

Matched-pair analysis of patients with female and male breast cancer: a comparative analysis

<p>Abstract</p> <p>Background</p> <p>Male breast cancer (MBC) is a rare disease accounting for approximately 1% of all breast carcinomas. Presently treatment recommendations are derived from the standards for female breast cancer. However, those approaches might be inadequate because of distinct gender specific differences in tumor biology of breast cancer. This study was planned in order to contrast potential differences between female and male breast cancer in both tumor biological behavior and clinical management.</p> <p>Methods</p> <p>MBC diagnosed between 1995-2007 (region Chemnitz/Zwickau, Saxony, Germany) was retrospectively analyzed. Tumor characteristics, treatment and follow-up of the patients were documented. In order to highlight potential differences each MBC was matched with a female counterpart (FBC) that showed accordance in at least eight tumor characteristics (year of diagnosis, age, tumor stage, nodal status, grade, estrogen- and progesterone receptors, HER2 status).</p> <p>Results</p> <p>108 male/female matched-pairs were available for survival analyses. In our study men and women with breast cancer had similar disease-free (DFS) and overall (OS) survival. The 5-years DFS was 53.4% (95% CI, range 54.1-66.3) in men respectively 62.6% (95% CI, 63.5-75.3) in women (p > 0.05). The 5-years OS was 71.4% (95% CI, 62.1-72.7%) and 70.3% (95% CI, 32.6-49.6) in women (p > 0.05). In males DFS analyses revealed progesterone receptor expression as the only prognostic relevant factor (p = 0.006). In multivariate analyses for OS both advanced tumor size (p = 0.01) and a lack of progesterone receptor expression were correlated (p = 0.01) with poor patients outcome in MBC.</p> <p>Conclusion</p> <p>Our comparative study revealed no survival differences between male and female breast cancer patients and gives evidence that gender is no predictor for survival in breast cancer. This was shown despite of significant gender specific differences in terms of frequency and intensity of systemic therapy in favor to female breast cancer.</p

Towards the Human Colorectal Cancer Microbiome

Multiple factors drive the progression from healthy mucosa towards sporadic colorectal carcinomas and accumulating evidence associates intestinal bacteria with disease initiation and progression. Therefore, the aim of this study was to provide a first high-resolution map of colonic dysbiosis that is associated with human colorectal cancer (CRC). To this purpose, the microbiomes colonizing colon tumor tissue and adjacent non-malignant mucosa were compared by deep rRNA sequencing. The results revealed striking differences in microbial colonization patterns between these two sites. Although inter-individual colonization in CRC patients was variable, tumors consistently formed a niche for Coriobacteria and other proposed probiotic bacterial species, while potentially pathogenic Enterobacteria were underrepresented in tumor tissue. As the intestinal microbiota is generally stable during adult life, these findings suggest that CRC-associated physiological and metabolic changes recruit tumor-foraging commensal-like bacteria. These microbes thus have an apparent competitive advantage in the tumor microenvironment and thereby seem to replace pathogenic bacteria that may be implicated in CRC etiology. This first glimpse of the CRC microbiome provides an important step towards full understanding of the dynamic interplay between intestinal microbial ecology and sporadic CRC, which may provide important leads towards novel microbiome-related diagnostic tools and therapeutic interventions

Giant Fibroadenoma Growing Rapidly During Pregnancy

Introduction: Giant fibroadenoma is a rare disease with unknown etiology During pregnancy fibroadenomas increase in size and may show lactational histologic changes. High concentrations of estrogen, progesterone, and prolactin promote the ductal growth and formation of tubuloalveolar structures.This may be a reason for the significant enlargement in this period. Case Presentation: We presented a case of giant fibroadenoma, first detected at the onset of pregnancy, which grew rapidly and was excised surgically two months after the birth. There was no marked deformity in the breast nor a need to reconstruct it, despite the giant mass was excised and the mother was lactating. Discussion: We presented a rare case of giant fibroadenoma in a lactating woman. A progressively growing mass in breast can lead to structural damages. The current management approach for giant fibroadenomas is still surgical excision

Abstract P1-11-04: Long-term patient satisfaction with cosmetic outcome and psychosocial wellbeing after breast conserving therapy is affected only by lumpectomy volume

Abstract Introduction: Breast conserving therapy (BCT) is considered the treatment of choice for early stage breast cancer by National Cancer Institute guidelines. Little data exists on patient-reported satisfaction and quality of life outcomes after lumpectomy with radiation. This study aims to identify factors influencing satisfaction with cosmetic outcome and quality of life in patients receiving BCT using a validated instrument. Methods: All patients treated with lumpectomy and radiation for breast cancer at our institution from 1997-2012 received a mailed questionnaire containing the BREAST-Q breast conservation module (graciously provided by Dr A. Pusic, Memorial Sloan Kettering Cancer Center), a validated quality of life survey instrument. A retrospective chart review was performed for survey responders for demographic, treatment, and staging information. Scores were calculated for satisfaction with appearance of the breast, adverse effects of radiation, sexual wellbeing, psychosocial wellbeing and physical wellbeing: upper body and arm. Pearson correlation coefficients were obtained. Wilcoxon rank-sum and one-way ANOVA were used to identify associations between patient variables and satisfaction scores. Multivariate regression was used to assess confounding variables. Results: A total of 110 questionnaires (response rate of 29.5%) fit criteria for analysis. The mean age of respondents was 65.9±11.2 yrs, and mean time since diagnosis was 91.8±53.1 mos. We observed the strongest correlations between satisfaction with breast appearance and sexual wellbeing (r=0.66, p&amp;lt;0.01), breast appearance and psychosocial wellbeing (r=0.62, p&amp;lt;0.01), and fewer effects of radiation and physical wellbeing (r=0.65, p&amp;lt;0.01). Lumpectomy volume was associated with decreased satisfaction with breast appearance (r=-0.32, p &amp;lt;0.01) and psychosocial wellbeing (r=-0.19, p&amp;lt;0.05). There was no correlation between satisfaction with breast appearance and patient age, time since surgery, history of re-excision, stage or localization technique. Patients with older age at diagnosis reported significantly fewer effects of radiation and better psychosocial, physical, and sexual wellbeing (all p&amp;lt;0.05) (Table 1). The incidence of recurrence was 2.7% and did not impact satisfaction scores.

Increasing age at diagnosis was associated with greater satisfaction in multiple domains. These results emphasize the importance of precise surgical technique and patient selection in order to achieve long-term patient satisfaction with BCT.
