Prognostic impact of early tumor shrinkage and depth of response in patients with microsatellite instability-high metastatic colorectal cancer receiving immune checkpoint inhibitors.

Background: Immune checkpoint inhibitors (ICIs) are the new standard of care in microsatellite instability-high (MSI-H)/deficient mismatch repair (dMMR) metastatic colorectal cancer (mCRC). Since tumor response dynamic parameters already shown a strong association with survival outcomes in patients with mCRC treated with first-line therapy, we investigated the association of early tumor shrinkage (ETS) and depth of response (DoR) in patients with MSI-H/dMMR mCRC treated with ICIs.

Methods: This is a retrospective, multicenter, cohort study in patients with dMMR and/or MSI-high mCRC treated with ICIs (anti-PD-1/PD-L1 with or without anti-CTLA-4 agents) with measurable disease and at least one post-baseline radiological disease reassessment.

Outcome of patients with colorectal cancer undergoing lung metastases resection: a single-institution retrospective analysis.

Introduction: This study was undertaken to review a single-institution cohort of patients with metastatic colorectal cancer undergoing lung resection after a multidisciplinary evaluation and to investigate the main prognostic factors for survival.

Methods: Medical records of 129 patients undergoing lung metastasectomy for colorectal cancer with curative intent from 2001 to 2017 were reviewed. Tissue samples from the primary tumor were analyzed with a multiplex genotyping system for the detection of mutations in and genes.

An overview on clinical, pathological and molecular features of lung metastases from colorectal cancer.

: Lung metastases occur in 10-20% of patients with colorectal cancer (CRC). Most of them are treated with palliative intent and have a poor prognosis. Pulmonary metastasectomy may be a curative option for carefully selected patients with 5-year survival rates ranging from 25% to 60%.

Immunotherapy in Gastrointestinal Cancers.

Gastrointestinal cancers represent a major public health problem worldwide. Immunotherapeutic strategies are currently under investigation in this setting and preliminary results of ongoing trials adopting checkpoint inhibitors are striking. Indeed, although a poor immunogenicity for GI has been reported, a strong biological rationale supports the development of immunotherapy in this field.

Anti-EGFR monoclonal antibody panitumumab for the treatment of patients with metastatic colorectal cancer: an overview of current practice and future perspectives.

Targeted agents alone or in combination with chemotherapy are current standard of treatment for metastatic colorectal cancer (mCRC). Panitumumab is a fully human monoclonal antibody which inhibits the epidermal growth factor receptor (EGFR). It is currently approved in combination with chemotherapy in first- and second-line and as a monotherapy in chemorefractory patients.

Multimodality treatment of gynecomastia in patients receiving antiandrogen therapy for prostate cancer in the era of abiraterone acetate and new antiandrogen molecules.

Gynecomastia is a pathological enlargement of male breasts due to hormonal imbalance and elevation of estrogens at the expense of testosterone. It is very important to diagnose this disease precociously because it can be the expression of different underlying pathologies. Besides genetic, chromosomal or chronic diseases, drugs often represent the principal cause of this hormonal disequilibrium.

Clinical and pathological features of primary renal synovial sarcoma: analysis of 64 cases from 11 years of medical literature.

Objective: To describe, for the first time, the clinical characteristics of primary renal synovial sarcoma (SS) and to examine the association of histological features with the expression of immunohistochemical markers.

Patients And Methods: We collated published data on all cases of primary renal SS, from its first description in 2000 to September 2011. Data on clinical and pathological characteristics were extracted and used to create a database.
