Carbon ‐ion radiotherapy combined with chemotherapy for head and neck mucosal melanoma: Prospective observational study

This study aimed to evaluate the efficacy of carbon ‐ion radiotherapy in combination with chemotherapy using dacarbazine, nimustine, and vincristine (DAV therapy) in mucosal melanoma. Twenty‐one patients with clinically localized mucosal melanoma of the head and neck were enrolled. The primary endpoint was 3‐year overall survival (OS). Secondar y endpoints included local control, progression‐free survival (PFS), and adverse event occurrence. Carbon‐ion radiotherapy with a dose of 57.6‐64.0 Gy (relative biological effectiveness) in 16 fractions was delivered concurrently with DAV therapy, and 2 cycles of adjuvant DAV therapy were admi nistered every 6 weeks. The median follow‐up periods were 15.5 months for all patients, and 31.2 months for 12 surviving patients. All patients had locally advanced T4a or T4b disease in the rhino‐sinus area. In 16 patients (76.2%), 3 cycles of planned DAV therapy were completed. The 3‐year OS and PFS rates were 49.2% and 37.0% respectively. The 3‐year local control rate was 92.3%. Eleven patients (52%) developed distant metastasis, which was the most frequent pattern of the first failure. Commonly presenting acute grade 2‐3 toxicities associated with radiotherapy and chemotherapy were mucositis (11 patients [53%]) and leukopenia (9 patients [43%]), which improved with conservative therapy. None of the patients developed grade 3 or greater late toxicities. Carbon‐ion radiotherapy in combination with DAV ther...

Authors: Hurwitz MD Abstract Hyperthermia holds great promise to advance immunotherapy in the treatment of cancer. Multiple trials have demonstrated benefit with the addition of hyperthermia to radiation or chemotherapy in the treatment of wide-ranging malignancies. Similarly, pre-clinical studies have demonstrated the ability of hyperthermia to enhance each of the 8 steps in the cancer-immunotherapy cycle including stimulation of tumor-specific immunity. While there has been an extensive recent focus on augmenting immunotherapy with radiation, surprisingly to date, there have been no clinical trials assessing the ...

Electrochemotherapy has been used successfully for treatment of recurrent head and neck skin cancers and skin metastasis. It combines both electroporation and chemotherapy. The authors report 4 patients, who all had metastatic periorbital malignancy. These patients were palliative with widespread metastatic malignancy. All patients had either already had multiple procedures or declined surgical resection and preferred less involved measures. The authors report technique and outcomes. Patient 1: 83-year-old man with recurrent malignant melanoma (MM) nodules (BRAF negative) in the left medial orbit and medial canthal area af...

CONCLUSION: irPR features are consistent across tumor types and treatment settings. Standardized, pan-tumor immune-mediated pathologic response criteria (irPRC) are defined and associated specimen-handling considerations are described. Future, prospective studies are merited to validate irPRC in larger datasets and to associate pathologic features with long-term patient outcomes. PMID: 31672770 [PubMed - as supplied by publisher]

A research team from the Duke University Medical Center and the Massachusetts Institute of Technology has uncovered a new compound with potential to make chemotherapy more effective in treating various cancers. The small-molecule inhibitor drug — JH-RE-06 — showed an ability to better-sensitize tumors to Cisplatin, the popular chemotherapy drug most often used for mesothelioma cancer patients. When combined with Cisplatin, the drug also showed an ability to prevent those tumor cells from becoming treatment resistant, a common problem with this rare cancer caused by asbestos exposure. The research was done on l...

ConclusionsPositive surgical margin and distant failure are the only independent prognostic factors for DSS. Tumor depth can predict distant failure. SLNB may be a valuable staging tool for the node-negative neck.

Lung cancer remains the leading cause of cancer deaths worldwide[1]. Non-small cell lung cancer (NSCLC) represents 80-90% of lung primary malignancies. NSCLC is most often diagnosed at a metastatic stage, where 5-year survival rate ranges between 0 and 5% using traditional chemotherapy-based strategies[2]. The recent introduction of immune checkpoint inhibitors (ICI), has resulted in an increase in overall survival (OS) rates of patients with advanced NSCLC, as well as melanoma, urothelial carcinoma, renal cell carcinoma and head and neck carcinoma.

Discussion MDSCs violently emerge in pathological conditions in an attempt to limit potentially harmful immune and inflammatory responses. Mechanisms supporting their expansion and survival are deeply investigated in cancer, in the perspective to reactivate specific antitumor responses and prevent their contribution to disease evolution. These findings will likely contribute to improve the targeting of MDSCs in anticancer immunotherapies, either alone or in combination with immune checkpoint inhibitors. New evidence indicates that the expansion of myeloid cell differentiation in pathology is subject to fine-tuning, as its...

In this study, we evaluated the therapeutic benefit of combining the TAB004 antibody with Liposomal-MSA-IL-2 in immune competent and human MUC1 transgenic (MUC1.Tg) mouse models of PDA and investigated the associated immune responses. Treatment with TAB004 + Lip-MSA-IL-2 resulted in significantly improved survival and slower tumor growth compared to controls in MUC1.Tg mice bearing an orthotopic PDA.MUC1 tumor. Similarly, in the spontaneous model of PDA that expresses human MUC1, the combination treatment stalled the progression of pancreatic intraepithelial pre-neoplastic (PanIN) lesion to adenocarcinoma. Treatment with t...
