The paradoxical role of reactive oxygen species in cell death versus cell survival establishes a delicate balance between chemotherapy efficacy and management of detrimental side effects. Normal proliferative signaling requires that cells remain inside a redox range that allows reversible protein oxidation to occur. Shifting the redox environment toward highly reducing or oxidizing states leads to cellular stress and cell death. Reactive oxygen species produced in response to Taxol and cisplatin treatment are necessary for effective cancer cell killing but the same ROS leads to damaging side effects in normal tissues...

Stereotactic radiosurgery has revolutionized the management of brain metastases. It delivers focused, highly conformal, ionizing radiation to a tumor delineated using high-resolution imaging, with low toxicity to adjacent brain structures. Randomized controlled and prospective trials have demonstrated a survival advantage and high local control rates after stereotactic radiosurgery for metastatic disease to the central nervous system, including for up to 10 brain metastases. Its minimal-access nature makes it an attractive alternative to surgical resection...

INTRODUCTION: Nausea and vomiting are common side effects in cancer patients treated with chemotherapy. Proper control of these symptoms might improve quality of life in these patients. Addition of cannabinoids to standard antiemetic treatment has been proposed in order to improve control of these symptoms. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others...

In solid tumors, the presence of lymph node-like structures called tertiary lymphoid structures (TLS) is associated with improved patient survival. However, little is known about how TLS form in cancer, how their function affects survival, and whether they are affected by cancer therapy. In this study, we used multi-spectral microscopy, quantitative pathology and gene expression profiling to analyze TLS formation in human lung squamous cell carcinoma (LSCC) and in an experimental model of lung TLS induction...

OBJECTIVE: Symptomatic therapy is an intervention centred entirely on the symptom management and pain relief. The utilization of charcoal in diarrhea management is a pertinent example of this type of medical care. Diarrhea is an ailment defined as an escalation in the frequency of bowel movements, unformed stool, abdominal discomfort and pain. These symptoms can be extremely debilitating for patients and effectuate frustration as well as severely damping mood and overall well-being. This narrative review aims to explore the use of charcoal in diarrhea management and its possible benefits in alleviating discomfort associated with these symptoms...

REVIEW
Karli Montague, Marzia Malcangio
In cancer treatments a dose-limiting side-effect of chemotherapeutic agents is the development of neuropathic pain, which is poorly managed by clinically available drugs at present. Chemotherapy-induced painful neuropathy (CIPN) is a major cause of premature cessation of treatment and so a greater understanding of the underlying mechanisms and the development of novel, more effective therapies, is greatly needed. In some cases, only a weak correlation between chemotherapy-induced pain and neuronal damage is observed both clinically and preclinically...

Background: Glioblastoma is the commonest form of malignant brain tumour in adults, affecting 2-3 people per 100,000 per year. Despite current treatment options including surgical resection, radiotherapy and temozolomide chemotherapy, overall survival at 2 years is approximately 27%, with a median survival of 12-14 months. The ketogenic diet (KD) is postulated to work by simulating the metabolic response to fasting by promoting the utilisation of ketones as a primary energy source, and depriving the glycolytic pathways utilised by malignant glioma cells for growth...

Martin Arthur Korzeniowski, Juanita Mary Crook
Penile cancer is a rare clinical entity that contributes to significant patient morbidity and mortality. Human papilloma virus (HPV) plays an important role in the carcinogenesis of penile squamous cell carcinoma (SCC), is associated with improved clinical outcomes, and is predictive for response to treatment with chemotherapy and radiotherapy. Historically, treatment consisted of radical surgery with partial or total penectomy. While effective for local control, surgical resection can impart significant physical, psychological and sexual dysfunction for afflicted men...

The prognosis of cancer patients is constantly improving, which increases the importance of securing long-term quality of life. While therapy of treatment-related disability mostly succeeds a cancer-specific treatment, physicians' awareness of simultaneous supportive therapy is rising. Early interventions such as physical exercise during chemotherapy are effective in reducing conditions such as fatigue. Specific sensorimotor training is able to improve or even prevent impairment of balance caused by neurotoxic agents...

Cyclophosphamide is an alkylating agent widely used for the treatment of malignant neoplasia and which can be used in the treatment of multiple rheumatic diseases. Medication administration errors may lead to its reduced efficacy or increased drug toxicity. Many errors occur in the administration of injectable drugs. The present study aimed at structuring a routine for cyclophosphamide use, as well as creating a document with pharmacotherapeutic guidelines for the patient. The routine is schematized in three phases: pre-chemotherapy, administration of cyclophosphamide, and post-chemotherapy, taking into account the drugs to be administered before and after cyclophosphamide in order to prevent adverse effects, including nausea and hemorrhagic cystitis...

Chemotherapy-induced neuropathic pain is a distressing and commonly occurring side effect of many commonly used chemotherapeutic agents, which in some cases may prevent cancer patients from being able to complete their treatment. Cannabinoid based therapies have the potential to manage or even prevent pain associated with this syndrome. Pre-clinical animal studies that investigate the modulation of the endocannabinoid system (endogenous cannabinoid pathway) are being conducted to better understand the mechanisms behind this phenomenon...

BACKGROUND: Immunotherapy has historically been of interest in the management of metastatic renal cell cancer (mRCC) because of its relative chemoresistance and the reproducible but low incidence of spontaneous remission in metastatic disease. Recently, targeted immunotherapies in the form of checkpoint inhibitors have shown durable responses in approximately 20%-30% of patients with solid tumors, with a much more acceptable side-effect profile. Anti-programmed death receptor 1 (PD-1)/programmed death receptor ligand 1 antibodies rely on the presence of host T cells in the tumor microenvironment to be stimulated in order to activate an antitumor response...

BACKGROUND: Sarcomas are rare, heterogeneous tumors for which prognosis remains dismal in patients with advanced disease. Pazopanib, a vascular endothelial growth factor receptor inhibitor, has shown modest efficacy in patients with soft tissue sarcoma who fail cytotoxic chemotherapy. The cytotoxic agent temozolomide has also demonstrated activity in patients with advanced sarcoma. OBJECTIVE: We performed a retrospective case series to evaluate the feasibility of adding temozolomide to pazopanib in advanced sarcoma patients following single-agent pazopanib failure...

Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) comprise approximately 15% of all childhood malignancies. Cure rates for both lymphoma entities have evolved tremendously during the last couple of decades, raising the 5-year survival rates to almost 100% for HL and to 85% for NHL. The mainstay therapy for both malignancies is still chemotherapy-with different regimens recommended for different types of disease. In HL, combined modality treatment, i.e., chemotherapy followed by radiotherapy, has long been the standard regimen...

Cancer patients are often poly-symptomatic which distressingly affects their quality of lives (QOLs). Alhough, conventional management provides adequate symptom control, yet is coupled with some limitations. Complementary therapies (CTs) have shown beneficial effects in cancer patients for symptomatic relief. The aim of this article is to provide evidence-based review of commonly used CTs for symptom management in cancer care. Hypnosis has promising evidence to be used for managing symptoms such as pain, chemotherapy-induced nausea/vomiting, distress, fatigue, and hot flashes...

Endocrine therapy (ET) of hormone receptor (HR)-positive and human epidermal growth factor receptor 2-(HER2)-negative metastatic breast cancer (MBC) historically focused on estrogen deprivation and antagonism. The identification of several intracellular pathways promoting resistance to antiestrogen therapy led to the introduction of novel endocrine drug combinations that reformed treatment schema and expanded therapeutic options. There is no doubt that efforts to overcome or delay resistance to ET are fruiting, particularly with the introduction of cyclin-dependent kinase 4/6 inhibitors such as palbociclib and ribociclib, and mechanistic target of rapamycin inhibitors such as everolimus...

Globally, > 5-10 million people are estimated to be infected with Human T-lymphotropic virus type 1 (HTLV-1), of whom ~ 5% develop adult T-cell leukemia/lymphoma (ATL). Despite advances in chemotherapy, overall survival (OS) has not improved in the 35 years since HTLV-1 was first described. In Europe/USA, combination treatment with zidovudine and interferon-α (ZDV/IFN-α) has substantially changed the management of patients with the leukemic subtypes of ATL (acute or unfavorable chronic ATL) and is under clinical trial evaluation in Japan...

In cancer, epilepsy can be the manifestation of a primary brain tumour, metastatic disease, vascular or surgical complications, opportunistic infection or secondary to anti-tumour therapy. Seizures are frequently the first symptom of a brain tumour. The epilepsy is related to elevated extracellular glutamate stimulating NMDA- and AMPA-receptors and to the formation of D-2HG which resembles glutamate in IDH1 mutated gliomas. Epilepsy as presenting sign is associated with a longer survival in low- and high- grade gliomas, particularly with the IDH1 mutation...
