Folic acid relieves bone cancer pain by downregulating P2X2/3 receptors in rats.

BACKGROUND: Bone cancer pain (BCP) remains a clinical challenge due to the limited and side effects of therapeutic methods. Folic acid has been known as an FDA approved dietary supplement and proved to have an analgesic effect in neuropathic pain. Here we investigate the role and mechanism of folic acid in bone cancer pain of a rat model. METHODS: Walker 256 tumor cells were inoculated into the left tibia of rats to induce bone cancer pain model. Pain reflex were assessed by paw withdrawal threshold (PWT) response to Von Frey filaments and paw withdrawal latency (PWL) response to thermal stim…

Low-dose naltrexone's utility for non-cancer centralized pain conditions: a scoping review.

BACKGROUND: At low doses, naltrexone (LDN) has been shown to modulate inflammation through the interruption of microglial cell activation within the central nervous system. One of the most likely contributors to centralized pain is changes in microglial cell processing. Therefore, it has been postulated that LDN can be used to manage patients with pain resulting from central sensitization due to this relationship. This scoping review aims to synthesize the relevant study data for LDN as a novel treatment strategy for various centralized pain conditions. METHODS: A comprehensive literature sea

Does interpretation bias moderate the relationship between pain and fear of cancer recurrence?

OBJECTIVE: The Cancer Threat Interpretation model proposes that clinically significant fear of cancer recurrence/progression (FCR/P) can occur when people misinterpret ambiguous physical symptoms as a sign of recurrence. The aim of this research is to test whether interpretation biases moderate the relationship between pain and FCR/P in women with breast cancer, as predicted. METHOD: One hundred forty-seven women with breast cancer completed questionnaire measures of demographic and medical information, FCR/P, interpretation bias, and symptom burden, as well as other known predictors of FCR/P

Morphological and functional brain changes in chronic cancer-related pain: A systematic review.

The purpose of this study was to perform a systematic review of the available literature on morphological and functional brain changes measu … there is some evidence that alterations occur in brain networks also involved in other chronic non-cancer pain syndromes. However, the low sample sizes of the studies, finding inconsistencies, and methodological heterogeneity do not allow for robust conclusions.

Intra-abdominal cancer risk with abdominal pain: a prospective cohort primary care study.

BACKGROUND: Quantifying cancer risk in primary care patients with abdominal pain informs diagnostic strategies. AIM: To quantify oesophagogastric, colorectal, liver, pancreatic, ovarian, uterine, kidney, and bladder cancer risks associated with newly reported abdominal pain with or without other symptoms, signs, or abnormal blood tests (that is, features) indicative of possible cancer. DESIGN AND SETTING: This was an observational prospective cohort study using Clinical Practice Research Datalink records with English cancer registry linkage. METHOD: The authors studied 125 793 patients aged

Botulinum Toxin Injection for Intractable Pain in Cancer Patients With Psoas Muscle Invasion.

Muscle invasion (MI) in patients with far-advanced cancer is often accompanied with pain. Conventional treatments used for pain relief may be associated with several side effects. We describe two cases of botulinum toxin injection (BTI) for relieving intractable pain in patients of far-advanced cancer having MI. The patients presented with persistent intractable pain that did not respond to conventional treatments, such as analgesic medications, epidural steroid injection, and radiotherapy. BTI relieved the intractable pain in these cases for at least 9-12 weeks without any reported side effec

Group-based trajectory analysis of postoperative pain and outcomes after liver cancer surgery.

BACKGROUND: Although previous studies have shown connections between pain and worse cancer outcomes, few clinical studies have evaluated their direct association, and the current study aimed to investigate the potential association between acute pain trajectories and postoperative outcomes after liver cancer surgery. METHODS: This retrospective study was conducted in a single medical center and included patients who received liver cancer surgery between January 2010 and December 2016. Maximal pain intensity was recorded daily using a numerical rating scale during the first postoperative week.

Percutaneous retrocrural versus ultrasound-guided coeliac plexus neurolysis for refractory pancreatic cancer pain.

We report a successful case of fluoroscopic percutaneous retrocrural coeliac plexus neurolysis (PRCPN) for pancreatic cancer pain refractory to endoscopic ultrasound-guided coeliac plexus neurolysis (EUS-CPN). A 55-year-old man with upper abdominal pain due to end-stage pancreatic cancer underwent EUS-CPN. Although CT revealed distribution of the contrast medium with neurolytic agent around the left and cephalic sides of the coeliac artery, the pain did not improve and became even more severe. PRCPN was performed, resulting in the drastic improvement of pain immediately. PRCPN should be consid…

Scorpion alleviates bone cancer pain through inhibition of bone destruction and glia activation.

BACKGROUND: Bone cancer pain is common in patients with advanced cancers as tumor metastasizes to bone. The inefficient clinical treatment severely reduces quality of life of bone cancer pain patients. During the pain status, activated spinal astrocytes and microglia release various inflammatory cytokines, resulting in spinal inflammation and the development of neuron sensitization. Scorpion is the dry body of Buthus martensii Karsch and is often used for various pain management in clinical practice. However, its function on bone cancer pain is unclear. METHODS: We investigated the effects of…

Factors Associated with Depression in African American Patients Being Treated for Cancer Pain.

BackgroundAmong cancer patients in the United States, African American cancer patients have the highest mortality rate and shortest survival rate. Although depression is known as a predictor of mortality in cancer and a potential barrier to health care utilization, research on depression in African American patients is limited. Cancer pain can interfere with an individual's ability to cope with depression.AimsTo identify factors that are associated with a positive screening of depressive symptoms assessed by the PHQ-8 in African American patients treated for cancer pain.DesignSecondary data an…

Illicit opioid use following changes in opioids prescribed for chronic non-cancer pain.

BACKGROUND: After decades of increased opioid pain reliever prescribing, providers are rapidly reducing prescribing. We hypothesized that reduced access to prescribed opioid pain relievers among patients previously reliant upon opioid pain relievers would result in increased illicit opioid use. METHODS AND FINDINGS: We conducted a retrospective cohort study among 602 publicly insured primary care patients who had been prescribed opioids for chronic non-cancer pain for at least three consecutive months in San Francisco, recruited through convenience sampling. We conducted a historical reconstr…

Peripheral nerve injury and sensitization underlie pain associated with oral cancer perineural invasion.

Cancer invading into nerves, termed perineural invasion (PNI), is associated with pain. Here, we show that oral cancer patients with PNI report greater spontaneous pain and mechanical allodynia compared with patients without PNI, suggesting that unique mechanisms drive PNI-induced pain. We studied the impact of PNI on peripheral nerve physiology and anatomy using a murine sciatic nerve PNI model. Mice with PNI exhibited spontaneous nociception and mechanical allodynia. Perineural invasion induced afterdischarge in A high-threshold mechanoreceptors (HTMRs), mechanical sensitization (ie, decreas

Identifying predictive factors for neuropathic pain after breast cancer surgery using machine learning.

INTRODUCTION: Neuropathic pain (NP) remains a major debilitating condition affecting more than 26% of breast cancer survivors worldwide. NP is diagnosed using a validated 10-items Douleur Neuropathique - 4 screening questionnaire which is administered 3 months after surgery and requires patient-doctor interaction. To develop an effective prognosis model admissible soon after surgery, without the need for patient-doctor interaction, we sought to [1] identify specific pain characteristics that can help determine which patients may be susceptible to NP after BC surgery, and 2) assess the utility

METHODS: A literature review of articles about pain in late-stage patients with cancer, with a focus on abdominal pain, pain manage

Prescribing Trends of Palliative Care Team's Use of Dexamethasone for Cancer-Related Pain.

Opioids are first-line therapy for cancer-related pain. In addition, corticosteroids are commonly utilized as adjuvant analgesics for pain and other symptoms in the oncology setting with limited supporting data. A retrospective analysis was conducted evaluating adult hospitalized patients receiving opioids who received once-daily dexamethasone on the recommendation of a specialty palliative care team during their hospitalization from January 1, 2015, to January 1, 2016. Primary end point was to describe prescribing patterns of dexamethasone in this patient population and secondarily examining

Pain Outcomes After Celiac Plexus Block in Children and Young Adults with Cancer.

Purpose: The use of celiac plexus block (CPB) for abdominal pain has been extensively reported in adults. However, pediatric literature is limited to three single case reports and a series of three cases. This study evaluated the effectiveness of CPB in children and young adults (aged 8-20 years) with abdominal malignancies. Methods: Pain outcomes after CPB were evaluated in four children and young adults with cancer. Mean daily pain score (PS, 0-10) and morphine consumption (intravenous morphine equivalent daily [MED], mg/kg/day) before and after CPB were used to assess effectiveness. Results

Disease burden and pain in obese cancer patients with chemotherapy-induced peripheral neuropathy.

PURPOSE: Chemotherapy-induced peripheral neuropathy (CIPN) and obesity are prevalent in cancer survivors and decrease quality of life; however, the impact of the co-occurrence of these conditions has garnered little attention. This study investigated differences between obese and non-obese cancer survivors with CIPN and predictors of symptom burden and pain. METHODS: Patients with CIPN were administered the MD Anderson Symptom Inventory and a modified version of pain descriptors from the McGill Pain Inventory. Independent t tests assessed group differences between obese and non-obese survivor

Negative oncologic impact of poor postoperative pain control in left-sided pancreatic cancer.

AIM: To investigate the association between postoperative pain control and oncologic outcomes in resected pancreatic ductal adenocarcinoma (PDAC). METHODS: From January 2009 to December 2014, 221 patients were diagnosed with PDAC and underwent resection with curative intent. Retrospective review of the patients was performed based on electronic medical records system. One patient without records of numerical rating scale (NRS) pain intensity scores was excluded and eight patients who underwent total pancreatectomy were also excluded. NRS scores during 7 postoperative days following resection

Could kinesiology taping help mitigate pain, breathlessness and abdominal-related symptoms in cancer?

We present the case of a woman who was an amateur athlete diagnosed with primary breast cancer, and 10 years later with terminal metastatic cancer. This case report was prepared posthumously in co-operation with her next of kin (husband). The patient first presented to a sports physiotherapist (AR) for her pain-management and to help maintain physical fitness so that she could continue with sports and an active lifestyle. The patient continued with physiotherapy for several months to enable her to be active. However, when her health deteriorated significantly due to advancing cancer, the treat
