Neratinib is a tyrosine kinase receptor inhibitor used in the extended adjuvant therapy of early-stage breast cancer. After adjuvant trastuzumab therapy, neratinib reduces the risk of recurrence and, if taken within 1 year from trastuzumab, significantly improves the invasive disease-free survival of patients with early-stage human epidermal growth factor receptor-2 positive (HER2+) breast cancer with no increased risk of long-term toxicity. Diarrhea, the most common adverse event associated with neratinib use, deters some clinicians from prescribing this drug.

A novel class of drugs, antibody-drug conjugates (ADCs), are now rapidly emerging as highly effective treatments for solid tumours. ADCs conjugate conventional chemotherapeutics with highly selective targeted monoclonal antibodies. Anti-HER2 therapies selectively target cancer cells expressing human epidermal growth factor receptor 2 (HER2), among them trastuzumab has been the first HER2-targeting monoclonal antibody to achieve successful results that made it the backbone of anti-HER2 therapies.

MBC is a rare disease accounting for almost 1% of all cancers in men and less than 1% of breast cancer. Emerging data on the genetic drivers of predisposition for MBC are available and different risk factors have been associated with its pathogenesis. Genetic alterations, such as pathogenetic variants in BRCA1/2 and other moderate-/low-penetrance genes, along with non-genetic risk factors, have been recognized as pathogenic factors for MBC.

Nucleocytoplasmic transport has been found dysregulated in many types of cancer and is often described as a poor prognostic factor. Specifically, Exportin-1 (XPO1) has been found overexpressed in many tumors and has become an attractive target in molecular oncology and therapeutics development. The selective inhibitor of nuclear export, Selinexor, is one of the most scientifically interesting drugs that targets XPO1 in clinical development.

Octreotide long-acting repeatable (LAR) is largely used to treat functional and/or metastatic neuroendocrine neoplasms (NENs). Its effect in controlling carcinoid syndrome and partially reduce tumour burden is attributable to the ability of octreotide to bind somatostatin receptors (SSTRs) on the tumour and metastasis, regulating growth hormone secretion and cell growth. Notably, SSTRs are also expressed, at different levels, on Tregs.

Neuroendocrine neoplasms (NENs) comprise a heterogeneous group of rare malignancies, mainly originating from hormone-secreting cells, which are widespread in human tissues. The identification of mutations in ATRX/DAXX genes in sporadic NENs, as well as the high burden of mutations scattered throughout the multiple endocrine neoplasia type 1 (MEN-1) gene in both sporadic and inherited syndromes, provided new insights into the molecular biology of tumour development. Other molecular mechanisms, such as the NOTCH signalling pathway, have shown to play an important role in the pathogenesis of NENs.

Article Synopsis
  • Platinum-based chemotherapy is the standard front-line treatment for patients with pluri-metastatic NeuroEndocrine Neoplasms (NENs), but there are no established second-line options when the disease progresses; temozolomide (TMZ) has shown promise as an alternative.
  • A study conducted at a center in Naples, Italy, treated 26 patients with metastatic NENs using a metronomic schedule of TMZ (75 mg/m², one week on/one week off) between 2014-2017, monitoring toxicity and treatment response.
  • Results indicated a median overall survival of 28.3 months, with a disease control rate of 92.3% and no severe toxicities recorded

Objectives: Given their inclusion and exclusion criteria, randomized clinical trials (RCT) might not include a population that truly mirrors real life (RL). This raises concerns about the applicability of RCT results in clinical practice. We evaluated the efficacy of anti-HER2 treatment with pertuzumab combined with trastuzumab and a taxane as first-line treatment for HER2-positive metastatic breast cancer in a RL setting, and compared the safety results obtained in our population versus the experimental cohort of the CLEOPATRA RCT, which led to the approval of this therapy.

Neuroendocrine tumors (NET) are rare malignancies, with the most common site of origin being from the gastrointestinal tract, particularly the pancreas, small bowel and appendix. Pancreatic neuroendocrine tumors (PNETs) can be functional, hormone secreting tumors, and can have distinctive symptoms leading to the diagnosis. In contrast nonfunctional tumors, the majority of PNETs, usually present later either incidentally or due to tumor bulk symptoms.

Article Synopsis
  • Somatostatin analogs (SSAs) are usually used to manage symptoms of neuroendocrine tumors (NETs), not to shrink the tumors themselves.
  • A case study of a 63-year-old woman with metastatic ileum NET showed significant symptom relief and liver tumor reduction after 3 months of octreotide treatment.
  • This suggests that SSAs may help in reducing tumor size or staging, making surgery a possibility for patients with initially inoperable NETs.
