Practical consensus recommendations regarding the management of HER2 neu positive metastatic breast cancer

Metastatic breast cancer (MBC) is cancer that has spread from the breast to another part of the body or has come back in another distant location. Treatment options for MBC depend on several factors, including where the cancer has spread, the patient's overall health, and the levels of hormone receptors and HER2 in the tumour. Over-expression of HER2 is generally considered to be a negative prognostic feature because it accompanies an increase in breast cancer mortality. However, the development of agents that specifically target HER2 has improved the management of patients with these tumours.^{[7],[8],[9],[10]} This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at these practical consensus recommendations in regards with the use of these agents and the management of HER2 positive MBC for the benefit of community oncologists.

Practical consensus recommendations on management of HR + ve early breast cancer with specific reference to genomic profiling

Breast cancer is a heterogeneous disease and patients are managed clinically based on ER, PR, HER2 expression, and key risk factors. The use of gene expression assays for early stage disease is already common practice. These tests have found a place in risk stratifying the heterogeneous group of stage I–II breast cancers for recurrence, for predicting chemotherapy response, and for predicting breast cancer-related mortality. Most guidelines for hormone receptor (HR)–positive early breast cancer recommend addition of adjuvant chemotherapy for most women, leading to overtreatment, which causes considerable morbidity and cost. Expert oncologist discussed about strategies of gene expression assays and aid in chemotherapy recommendations for treatment of HR + ve EBC and the expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at this practical consensus recommendations for the benefit of community oncologists.

Endometriosis of the appendix presenting as acute appendicitis with unusual appearance

INTRODUCTION

Endometriosis of the appendix is an uncommon mimicker of acute appendicitis which makes for a diagnostic dilemma.

PRESENTATION OF CASE

We present a rare case of a menstruating woman presenting with classic symptoms of appendicitis, without the characteristic inflammatory changes seen on laparoscopy consistent with appendicitis. Instead, the appendix appeared unusually contracted on itself. Pathologic review of the appendix revealed microscopic findings of endometriosis.

DISCUSSION

We theorize the growth and shedding of the endometrial tissue during menstruation caused compression of the neural plexi in the wall of the appendix leading to the presentation mimicking acute appendicitis.

CONCLUSION

Given the potential for endometrial appendicitis, we propose appendectomy in reproductive age female patients with right lower quadrant pain, regardless of appendix appearance on laparoscopy.

Penile lymphoedema: approach to investigation and management

BACKGROUND

Penile lymphoedema (with and without cellulitis) is a rare, often chronic, clinically heterogeneous entity with an uncertain pathogenesis and an important differential diagnosis. It creates significant physical and psychosexual morbidity, and presents considerable therapeutic challenges. The existing literature is limited.

AIM

To describe and share our updated cumulative experience of a cohort of patients with penile lymphoedema.

METHODS

This was a retrospective review of the case records of patients with chronic penile lymphoedema seen in two dedicated male genital dermatology clinics between January 2011 and July 2016.

RESULTS

In total, 41 cases were identified. Over a third had Crohn disease (CD) (which was occult in one-third of these), and over a third had serological evidence of streptococcal infection. All patients responded to systemic antibiotics and specialized urological surgery circumcision and excision).

CONCLUSIONS

Penile lymphoedema should be investigated to exclude underlying pathology especially CD and streptococcal infection. Treatment with antibiotics should be considered early and long term to try to preserve the foreskin: most patients are uncircumcised. Some patients may benefit from a course or courses of oral steroids. The development of gross dysfunction of the prepuce usually dictates circumcision and excision of lymphoedematous tissue once the situation is medically stabilized.

Practical consensus recommendation on when to do BRCA testing

BRCA-mutation associated breast cancer and to future cancer risks and sensitivity to systemic therapies. Now that rapid genetic testing for BRCA1 and BRCA2 mutations is available, BRCA mutation status can be considered when making treatment and prevention decisions for BRCA testing, BRCA mutation carriers with breast cancer. Expert group used data from published literature, practical experience, and opinion of a large group of academic oncologists, to arrive at practical consensus recommendations for use by the community oncologists.

Self injection of foreign materials into the penis

Injection of the subcutaneous tissues of the penis for enlargement of penile girth has been practised for many years by laypeople and medical practitioners alike. However, with recognition of the complications, the practice has died out. We report a series of five patients who presented having injected foreign materials into the subcutaneous tissues of their penises, including paraffin and mineral oils. Our patients had a variable time course of presentation ranging from 1 day following injection to over 26 years. Self-injection of the subcutaneous tissues of the penis is an unusual presentation for a penile mass but should be considered as a differential diagnosis in patients with a long latent period to presentation or with characteristic magnetic resonance imaging and histological appearances.

Minimal Invasive Management of Lymph Nodes

Penile cancer is a rare genitourinary malignancy. Lymph node involvement is the single most important factor determining survival in these patients, and those patients with occult disease are difficult to identify on conventional cross-sectional imaging. Until recently, lymph node sampling (eg, lymphadenectomy) has been the diagnostic modality of choice in the detection of micrometastasis. More recently, several novel molecular and minimally invasive diagnostic techniques have been developed, which have been demonstrated to decrease the false-negative and -positive results of conventional imaging and lymphadenectomy. This article focuses on the minimally invasive management of lymph nodes in men with penile cancer.
