SEOM-GEINO clinical guidelines for high-grade gliomas of adulthood (2022).

High-grade gliomas (HGG) are the most common primary brain malignancies and account for more than half of all malignant primary brain tumors. The new 2021 WHO classification divides adult HGG into four subtypes: grade 3 oligodendroglioma (1p/19 codeleted, IDH-mutant); grade 3 IDH-mutant astrocytoma; grade 4 IDH-mutant astrocytoma, and grade 4 IDH wild-type glioblastoma (GB). Radiotherapy (RT) and chemotherapy (CTX) are the current standard of care for patients with newly diagnosed HGG. Several clinically relevant molecular markers that assist in diagnosis and prognosis have recently been identified. The treatment for recurrent high-grade gliomas is not well defined and decision-making is usually based on prior strategies, as well as several clinical and radiological factors. Whereas the prognosis for GB is grim (5-year survival rate of 5-10%) outcomes for the other high-grade gliomas are typically better, depending on the molecular features of the tumor. The presence of neurological deficits and seizures can significantly impact quality of life.

Real-world Data of Paclitaxel and Cetuximab in Recurrent/Metastatic Squamous Cell Carcinoma of the Head and Neck.

BACKGROUND/AIM: Prior immune-checkpoint inhibitors, weekly paclitaxel-cetuximab was one of the few options for platinum-ineligible patients with recurrent/ metastatic squamous cell carcinoma of the head and neck (R/M-SCCHN). This real-world study analyzed the long-term outcomes of this regimen. PATIENTS AND METHODS: A multicenter, retrospective, observational, cross-sectional, chart review study was realized in nine hospitals of the Galician Group of Head and Neck Cancer. Eligible population was adult platinum-ineligible patients with R/M SCCHN (unfit to, or after progressing following EXTREME or other platinum-based regimens) that received weekly paclitaxel plus cetuximab regimen as first- or second-line (1L or 2L) between January 2009 and December 2014. The efficacy was evaluated (1L-2L) in regards to overall survival (OS) and progression-free survival (PFS), and safety was assessed as the incidence of adverse events (AEs). RESULTS: Seventy-five R/M-SCCHN patients received the scheme (1L, n=50; 2L: n=25). The mean age of the patients was 59 years (1L, 59.5 years; 2L, 59.2 years), 90% were male (1L, 96%; 2L, 79%), 55% were smokers (1L, 60.4%; 2L, 45.8%), and 61% presented ECOG performance status (PS) 1 (1L, 54%; 2L, 62.5%). Median OS [interquartile range (IQR)] was 8.85 (4.22-40.96) months. Median PFS (IQR) was 8.5 (3.93-12.55) (1L) and 8.8 (5.62-16.91) (2L) months. Disease control rate was 60% (1L) and 85% (2L). Weekly paclitaxel-cetuximab was well tolerated in 1L/2L (cutaneous-toxicity, mucositis, neuropathy; mainly Grade 1-2). No grade 4 AEs were notified in 2L. CONCLUSION: Weekly paclitaxel-cetuximab is an active and well tolerated therapeutical option in platinum-ineligible or after platinum regimens in R/M-SCCHN patients.

Establishing an Expert Consensus on Key Indicators of the Quality of Life among Breast Cancer Survivors: A Modified Delphi Study.

(1) Background: The needs of cancer survivors are often not reflected in practice. One of the main barriers of the use of patient-reported outcomes is associated with data collection and the interpretation of patient-reported outcomes (PROs) due to a multitude of instruments and measuring approaches. The aim of the study was to establish an expert consensus on the relevance and key indicators of quality of life in the clinical practice of breast cancer survivors. (2) Methods: Potential indicators of the quality of life of breast cancer survivors were extracted from the established quality of life models, depicting survivors' perspectives. The specific domains and subdomains of quality of life were evaluated in a two-stage online Delphi process, including an international and multidisciplinary panel of experts. (3) Results: The first round of the Delphi process was completed by 57 and the second by 37 participants. A consensus was reached for the Physical and Psychological domains, and on eleven subdomains of quality of life. The results were further supported by the additional ranking of importance of the subdomains in the second round. (4) Conclusions: The current findings can serve to optimize the use of instruments and address the challenges related to data collection and interpretation as the facilitators of the adaption in routine practice.

Systematic review of cytokines and growth factors for the management of oral mucositis in cancer patients.

PURPOSE: The aim of this project was to review the literature and define clinical practice guidelines for the use of cytokines and growth factor agents for the prevention or treatment of oral mucositis induced by cancer chemotherapy or radiotherapy. METHODS: A systematic review was conducted by the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society for Oral Oncology (MASCC/ISOO). The body of evidence for each intervention, in each cancer treatment setting, was assigned an evidence level. Based on the evidence level, one of the following three guideline determinations was possible: Recommendation, Suggestion, No guideline possible. RESULTS: Sixty-four clinical studies across 11 interventions were evaluated. A recommendation was made for the use of recombinant human KGF-1 (palifermin) at a dose of 60 µg/kg per day for 3 days prior to conditioning treatment and for 3 days post-transplant for prevention of oral mucositis in patients receiving high-dose chemotherapy and total body irradiation followed by autologous stem cell transplantation for hematological malignancies. A suggestion was made against using granulocyte macrophage colony-stimulating factor mouthwash for the prevention of oral mucositis in the setting of high-dose chemotherapy followed by autologous or allogeneic stem cell transplantation. No guideline was possible for any other cytokine or growth factor agents due to inconclusive evidence. CONCLUSIONS: Of the cytokine and growth factor agents studied for oral mucositis, the evidence only supports use of palifermin in the specific population listed above. Additional well-designed research is needed on other cytokine and growth factor interventions and in other cancer treatment settings.

Role of pegylated liposomal doxorubicin (Caelyx) in the treatment of relapsing ovarian cancer.

The most significant factor predicting response to second-line chemotherapy is the time interval elapsed from the end of chemotherapy to relapse occurrence. Two types of situations may be considered: patients with platinum-sensitive relapse (relapse-free interval longer than 6 months) and patients with platinum-refractory relapse (progression during treatment or relapse-free interval under 6 months). Pegylated liposomal doxorubicin is a doxorubicin formulation. Encapsulation in liposomes confers it different pharmacokinetic characteristics and a more favorable toxicity profile. The following review examines the efficacy and safety of pegylated liposomal doxorubicin for the treatment of relapsing epithelial ovarian cancer.
