A meta-analysis of efficacy and safety data from head-to-head first-line trials of epidermal growth factor receptor inhibitors versus bevacizumab in adult patients with RAS wild-type metastatic colorectal cancer by sidedness.

The first-line treatment choice of EGFRIs plus doublet chemotherapy vs. bevacizumab plus doublet chemotherapy remains a topic of interest for patients with left-sided RAS WT mCRC. We conducted a systematic literature review and meta-analysis of clinical trial data published between 2015 and 2024.

SEOM guidelines for the treatment of bone metastases from solid tumours.

Bone metastases are a common and distressing effect of cancer, being a major cause of morbidity in many patients with advanced stage cancer, in particular in breast and prostate cancer. Patients with bone metastases can experience complications known as skeletal-related events (SREs) which may cause significant debilitation and have a negative impact on quality of life and functional independence. The current recommended systemic treatment for the prevention of SREs is based on the use of bisphosphonates: ibandronate, pamidronate and zoledronic acid- the most potent one- are approved in advanced breast cancer with bone metastases, whereas only zoledronic acid is indicated in advanced prostate cancer with bone metastases.

SEOM clinical guidelines for the adjuvant treatment of colorectal cancer.

Colorectal cancer is the third most common malignant neoplasm and the second cause of death by cancer in western countries. In this manuscript, the clinical guidelines of the Spanish Society of Medical Oncology (SEOM) for diagnosis and adjuvant treatment of colon cancer and rectal cancer are reported.

Trabectedin in pre-treated patients with advanced or metastatic soft tissue sarcoma: a phase II study evaluating co-treatment with dexamethasone.

Purpose: This study assesses the efficacy, toxicity and pharmacokinetic profile of trabectedin with or without prophylactic dexamethasone co-treatment in patients with recurrent advanced soft tissue sarcoma (STS).

Patients And Methods: Patients were randomized to receive trabectedin as a 3-h infusion every 3 weeks with dexamethasone or placebo in the first cycle, with the alternate in the second cycle and with the patient's choice subsequently. Due to toxicity, the randomized design was modified to open-label to make dexamethasone mandatory and the initial dose (1,650 μg/m(2)) was reduced to 1,500 μg/m(2) and then to 1,300 μg/m(2).

A panel discussion of controversies and challenges in the adjuvant treatment of colon cancer.

Current issues of adjuvant therapy for colon cancer concern the introduction of drugs other than fluorouracil-5/leucovorin (5-FU/LV), the benefits for stage II patients, the use of new primary endpoints and the influence of age on treatment benefits. These issues were addressed in a panel discussion and the conclusions were the following: FOLFOX4 is the first regimen that shows superiority over 5-FU/LV. The use of 3-year disease-free survival as primary endpoint could encourage the quicker adoption of improved therapeutic strategies into clinical practice.
