Special Issue Information

Dear Colleagues,

This Special Issue is the second edition of a previous Special Issue entitled “Cancer Pain: From Basic Research to Drug Discovery and Clinical Studies”  (https://www.mdpi.com/journal/cancers/special_issues/68V8460N1Q).

Cancer pain is one of the worst forms of chronic pain, with opioids being the mainstay of treatment. Unfortunately, most patients quickly develop opioid tolerance, leaving them with few therapeutic alternatives while battling this deadly disease. Thus, there is an urgent need to identify the molecular mechanisms driving cancer pain to develop novel analgesic drugs. Most cancer pain occurs when the tumor destroys tissues or presses on nerves. However, cancer cells can also produce substances that make normally innocuous stimuli feel painful. Furthermore, therapeutic interventions can induce pain as an adverse effect, as exemplified by chemotherapy-induced peripheral neuropathy.

With this Special Issue, we aim to explore the current state of the cancer pain field, from basic research through to drug discovery and the development to clinical trials. Original research papers, reviews, clinical studies, and meta-analyses of clinical trials are all welcome to contribute.

Dr. Arpad Szallasi

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cancers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

Background: The ways in which peripheral sensory nerves interact with osteosarcomas are important to understand because it could lead to development of new approaches to treat bone cancer pain. This study aimed to determine how cancer affects sensory nerve density and distribution in a murine model of osteosarcoma-induced bone pain. Methods: The femoral marrow cavities of male C3H/HeNHsd mice were injected with either NCTC 2472 primary osteosarcoma (cancer) cells or phosphate buffered saline (control). Pain behavior was assessed using limb use score and static weight bearing assays. At the experimental endpoint, femurs were collected, decalcified, immunolabeled, cleared and imaged using light sheet microscopy (Ultramicroscope Blaze, Miltenyi Biotec). The distribution of sensory nerves was traced through the marrow cavity of the proximal femur and the periosteum overlying the third trochanter (Imaris, Bitplane). Results: Weight bearing on the injected limb was decreased in osteosarcoma-injected but not saline-injected mice. Filament tracing revealed a reduced density of neurofilament 200 kDa-positive (NF200+; myelinated nerve marker) but not calcitonin gene-related peptide-positive (CGRP+; peptidergic nerve marker) sensory nerves in the marrow cavity of osteosarcoma-injected relative to saline-injected mice. There was increased density of CGRP+ but not NF200+ nerves in the periosteum of osteosarcoma-injected relative to saline-injected mice. Conclusions: Osteosarcoma differentially affects the density and distribution of different subtypes of peripheral sensory nerves in bone. Understanding how osteosarcomas affect different populations of sensory nerves could lead to more targeted mechanism-based treatments for bone cancer-induced pain. Full article
