HER2-positive breast cancer, accounting for 15 % of the total breast cancer patient population, carries in itself a bad prognosis, which has now become much better after the advent of anti-HER2 drugs. HER2-targeted therapy has significantly improved disease free- and overall survival in HER2-positive breast cancer, and has rendered better disease control both in the early and advanced disease setting. ⋯ The recent development of a subcutaneous formulation has meant a significant advance in this respect. We review the drug development of the compound and the current evidence on its use.

Age is an important feature at the time of early breast cancer diagnosis. Radiotherapy is a mandatory component of treatment for breast-conserving strategies in early disease stages. ⋯ Age and risk for local recurrence guide the decision-making process to electro-optimal treatment. Radiotherapy technological versatility offers multiple options for individualized (risk-age adapted) recommendations.

To assess the impact in pathological complete response (pCR) and outcome of two dose-dense neoadjuvant chemotherapy (DDNC) regimens among different histological subtypes determined by hormonal receptor (HR) and HER2 status in breast cancer patients. ⋯ HR-/HER2- and HR-/HER2+ subtypes had a high pCR rate to DDNC. HR-/HER2- tumors had a worse outcome compared to other tumor subtypes but no significant difference was observed among HR-/HER2- tumors that achieved a pCR.

Peritoneal carcinomatosis (PC) is a common form of tumour metastasis stemming from gastrointestinal and colorectal cancers. For a long time, PC has been considered a terminal clinical condition treated only with palliative systemic chemotherapy and associated with very limited results. During the last decade, the treatment of advanced colorectal disease has greatly improved with the emergence of new chemotherapy drugs and biological agents. ⋯ At least one phase III study and an important number of phase II studies have shown that CRS + HIPEC provides important survival benefits for patients with PC of colorectal origin. The combination of CRS + HIPEC is indicated for patients with good general health, a low PCI, absence of extra-abdominal metastasis and who can, technically, undergo CRS. The early identification of this group of patients, rapid referral to centres specialised in CRS + HIPEC, together with the correct application of this treatment, are key in achieving the best results.
