The randomized multicenter study on rapidly proliferating breast cancer, assessed according to thymidine labelling index (TLI), was activated at the end of the 1980s. The present work investigated whether and to what degree the short-term advantages observed from adjuvant CMF (cyclophosphamide, methotrexate, 5-fluorouracil) were maintained at a longer follow-up. Two hundred and eighty-one patients with node-negative and high TLI tumors were randomized to receive six cycles of CMF or no further treatment. At a median follow-up of 12 years, CMF produced a 25% and 20% relative reduction in relapse and death cumulative incidence, respectively. A breakdown analysis identified a subgroup of patients with intermediate proliferating tumors for whom a 70% and 73% reduction in relapse and death was observed in the intention-to-treat population. An even higher reduction of 80% and 84% in relapse and death was seen for the patients who had received the full CMF dose. We identified a subgroup of patients with intermediate proliferating tumors in whom the high benefit obtained from adjuvant CMF was maintained at a long-term follow up.

Checkpoint inhibitor pneumonitis (CIP) is a potentially fatal disease that can occur at any duration of treatment. Patients may present with vague respiratory symptoms such as progressive cough, dyspnea, and decreased activity tolerance. Among checkpoint inhibitors, CIP is higher in programmed death 1 (PD-1) inhibitors.

Background: Adjuvant chemotherapy for patients with early breast cancer improves outcomes but its toxicity affects patients' quality of life (QOL). The UK TACT2 trial investigated whether accelerated epirubicin improves time to recurrence and if oral capecitabine is non-inferior to cyclophosphamide, methotrexate, and fluorouracil (CMF) for efficacy with less toxicity. Results showed no benefit for accelerated epirubicin and capecitabine was non-inferior.

Background: HER2, TROP2 and PD-L1 are novel targets in triple-negative breast cancer (TNBC). The combined expression status of these targets, and whether they can define prognostic subgroups, is currently undefined.
Methods: Immunohistochemistry was used to determine HER2, TROP2 and PD-L1 levels in 459 TNBC cases, that received in the adjuvant/neoadjuvant setting active surveillance, CMF, anthracycline-, anthracycline plus taxane-, or carboplatin-containing regimes.

This study aimed to investigate the effect of chemotherapy (CT) and its different types of regimens on the anthropometry and body composition of women with breast cancer. Three-hundred-and-four women with breast cancer were enrolled in this multicenter study. The participants were evaluated before the infusion of the first cycle of CT (pre-CT), and until two weeks after CT completion (post-CT), regarding body weight, body mass index (BMI); waist circumference (WC); waist-to-height ratio (WHtR); conicity index (C-index); fat mass index (FMI); and fat-free mass index (FFMI).
