Retroperitoneal extension of massive ulcerated testicular seminoma through the inguinal canal: A case report.

INTRODUCTION: Testicular cancers represent about 5% of all urological malignancies and 1-1.5% of all male neoplasms. Most of the testicular cancers are localized (68%) at diagnosis. Bulky masses in the scrotum are rare. We present a rare case of bulky testicular cancer with retroperitoneal spread through the inguinal canal. CASE REPORT: A 44-year-old man came to the emergency department referring weakness and the presence of a scrotal mass. At physical examination, a voluminous mass was found, with necrotic phenomena within the scrotum. Abdomen was tense and sore. Abdominal CT scan revealed a bulky testicular mass spreading to the retroperitoneal space through the inguinal canal with node enlargement. Patient underwent orchiectomy with excision of infiltrated scrotum skin. Histologic diagnosis confirmed a typical form seminoma. The patient was then treated with a cisplatin-based chemotherapy, with a partial response. The patient recently relapsed and he is being treated with a new line of chemotherapy and subsequent surgery with or without radiotherapy. CONCLUSIONS: We described a rare presentation of testicular cancer. This case highlights the importance of a multidisciplinary approach to rare testis tumour presentation and early diagnosis for testicular cancers.

A multidisciplinary group for prostate cancer management: A single institution experience.

Increased knowledge regarding the heterogeneity of Prostate Cancer (PC) and its variable outcomes has generated controversy over the best clinical approach. Nowadays, it is well-known that patient outcomes and clinical management may be improved by an efficient organization of the national health care system. The Interdisciplinary Group for Oncological Care (GICO) for PC patients was created by our healthcare management company in September 2010. Since then, a multidisciplinary internal report was applied to PC patients. This report highlights our methodology and experience of planning a GICO, and illustrates the results obtained for the management of PC patients before and after the adopted GICO criteria in a single institution, the SS Annunziata Hospital (Chieti, Italy).

Long-term outcome of breast cancer patients with pathologic N3a lymph node stage.

PURPOSE: To evaluate factors influencing the long-term outcome of patients presenting with 10 or more metastatic axillary lymph nodes (pN3a) after surgery for primary breast cancer. METHOD: Between January 1990 and December 2015, a total of 130 patients with pN3a breast cancer at surgery were identified in our Institutions and included in the study. Twenty-nine of them (22.3%) received neoadjuvant chemotherapy. The Multivariate Cox proportional hazards model was used to determine independent prognostic factors associated with DFS and OS. RESULTS: After a median follow-up of 6.4 years (range 0.87-25 years), 2 patients had a local relapse, 59 distant metastases (1 with local relapse) and 52 patients died. The 5-year DFS and OS rates were 61.8% and 71.5%, respectively. At multivariate analysis, pN3a stage after neoadjuvant chemotherapy (ypN3a) was significantly associated with increased risk of recurrence (HR 1.92, p = 0.02) and death (HR 2.05, p = 0.029). Absence of progesterone receptor (PR) expression was the most important tumor characteristic associated with poor prognosis, both in terms of recurrence (HR 2.55, p < 0.001) and death (HR 2.23, p = 0.019). High levels of Ki-67 index (≥20%) were significantly associated with a shorter OS (HR 2.03, p = 0.027), but not with DFS. CONCLUSIONS: The results of this study indicate that ypN3a stage, lack of expression of PR, and Ki-67 ≥ 20% negatively affect long-term outcome of patients with pN3a breast cancer.

Is the skin a sanctuary for breast cancer cells during treatment with anti-HER2 antibodies?

The occurrence of skin metastases is a common event in patients affected by advanced breast cancer, usually associated with systemic disease progression. Here we describe 2 cases of diffuse cutaneous metastases from HER2-overexpressing breast cancer occurring despite a dramatic response in liver and bone, respectively, during treatment with anti-HER2 antibodies Trastuzumab and Pertuzumab. We discuss the reasons for this discrepancy and suggest a possible implication of impaired immune response in the skin. Future research should provide strategies to overcome the induction of immune privilege in the skin in order to avoid discontinuation of effective treatments.

Molecular mechanisms of endocrine resistance and their implication in the therapy of breast cancer.

The use of endocrine agents is a safe and effective treatment in the management of hormone-sensitive breast cancer. Unfortunately, sooner or later, tumor cells develop resistance to endocrine manipulation making useless this approach. During the last decade, new molecules and intracellular signaling pathways involved in endocrine resistance have been identified. Several studies have documented that estrogen receptor signaling may maintain a pivotal role in the tumor growth despite the failure of a previous hormonal treatment. In this review we will discuss the general principles for optimizing the choice of endocrine therapy based on an understanding of the molecular mechanisms responsible for resistance to the different anti-hormonal agents.
