Background: Numbness and tingling secondary to chemotherapy-induced peripheral neuropathy (CIPN) are frequent side effects that limit chemotherapy treatment and quality of life. Successful treatments for CIPN are limited. This preliminary report shows the potential long-term effects of ozone treatment in the management of persistent numbness and tingling secondary to CIPN.

Pain secondary to chemotherapy-induced peripheral neuropathy (CIPN) can limit the administration of chemotherapy, cancer-treatment outcomes, and the quality of life of patients. Oxidative stress and inflammation are some of the key mechanisms involved in CIPN. Successful treatments for CIPN are limited.

Serving as one of the few training institutions of medical oncology in the Philippines, the University of the Philippines-Philippine General Hospital was faced with challenges brought by the coronavirus 2019 disease (COVID-19) pandemic. With the dismantling of routines and practices in the hospital, training activities such as daily rounds, conferences, and examinations were temporarily put on hold. Recognizing that the strength of any clinical training program is its wealth of patients, the immediate resumption of patient services, albeit limited at first, had been instrumental in ensuring the continuation of training in our institution.

Chronic pain secondary to treatment in cancer survivors without tumor evidence is not unusual. Its management often requires specific approaches that are different from those applied for cancer patients with advanced disease and short life expectancy. Some studies have described clinical benefit with ozone therapy (OT) in the management of pain and side effects secondary to cancer treatment.

Introduction: This article provides an overview of the potential use of ozone as an adjuvant during cancer treatment.

Methods: We summarize the findings of the most relevant publications focused on this goal, and we include our related clinical experience.

Results: Over several decades, prestigious journals have published studies on the capacity of ozone to induce direct damage on tumor cells and, as well, to enhance the effects of radiotherapy and chemotherapy.

Aims: Relapsed high-grade gliomas (HGGs) have poor prognoses and there is no standard treatment. HGGs have ischemia/hypoxia associated and, as such, drugs and oxygen have low access, with increased resistance to chemotherapy and radiotherapy. Tumor hypoxia modification can improve outcomes and overall survival in some patients with these tumors.

Purpose: This study investigated whether sequential administration of erlotinib and chemotherapy improves clinical outcomes versus chemotherapy alone in unselected, chemotherapy-naïve patients with advanced non-small-cell lung cancer (NSCLC).

Patients And Methods: Previously untreated patients (n = 154) with stage IIIB or IV NSCLC and Eastern Cooperative Oncology Group performance status of 0 or 1 were randomly assigned to receive erlotinib (150 mg/d) or placebo on days 15 to 28 of a 4-week cycle that included gemcitabine (1,250 mg/m(2) days 1 and 8) and either cisplatin (75 mg/m(2) day 1) or carboplatin (5 x area under the serum concentration-time curve, day 1). The primary end point was nonprogression rate (NPR) at 8 weeks.

Purpose: Preclinical data showed that the combination of exemestane and celecoxib has synergistic effects. Therefore, a study was undertaken to explore the efficacy and tolerability of this combination in postmenopausal patients with advanced, hormone-sensitive breast cancer.

Patients And Methods: A randomized phase II study was conducted in postmenopausal patients with hormone-sensitive breast cancer and measurable disease who had progressive disease after treatment with tamoxifen.
