BACKGROUND: Early palliative care (EPC) is an important aspect of cancer management but, to our knowledge, has never been evaluated in patients with head and neck cancer. Hence, we performed this study to determine whether the addition of EPC to standard therapy leads to an improvement in the quality of life (QOL), decrease in symptom burden, and improvement in overall survival. METHODS: Adult patients with squamous cell carcinoma of the head and neck region planned for palliative systemic therapy were allocated 1:1 to either standard systemic therapy without or with comprehensive EPC service referral. Patients were administered the revised Edmonton Symptom Assessment Scale and the Functional Assessment of Cancer Therapy for head and neck cancer (FACT-H&N) questionnaire at baseline and every 1 month thereafter for 3 months. The primary endpoint was a change in the QOL measured at 3 months after random assignment. All statistical tests were 2-sided. RESULTS: Ninety patients were randomly assigned to each arm. There was no statistical difference in the change in the FACT-H&N total score (P = .94), FACT-H&N Trial Outcome Index (P = .95), FACT-general total (P = .84), and Edmonton Symptom Assessment Scale scores at 3 months between the 2 arms. The median overall survival was similar between the 2 arms (hazard ratio for death = 1.01, 95% confidence interval = 0.74 to 1.35). There were 5 in-hospital deaths in both arms (5.6% for both, P = .99). CONCLUSIONS: In this phase III study, the integration of EPC in head and neck cancer patients did not lead to an improvement in the QOL or survival.

BACKGROUND: Oral mucositis related pain during CTRT in head and neck cancers is a common problem. Unfortunately, in spite of it being common, there is limited evidence for selection of systemic analgesic in this situation. Hence, this study was designed to compare the analgesic effect of a non-steroidal anti-inflammatory drug (diclofenac) versus a weak opioid (tramadol). PATIENTS AND METHODS: This was an open-label, parallel design, superiority randomised controlled study. In this study, head and neck cancer patients undergoing radical or adjuvant chemoradiation, who had grade 1 or above mucositis (in accordance with Common Terminology Criteria for Adverse Events version 4.03) and had pain related to it were randomly assigned to either diclofenac or tramadol for mucositis related pain control. The primary endpoint was analgesia after the first dose. The secondary endpoints were the rate of change in analgesic within 1 week, adverse events and quality of life. RESULTS: One hundred and twenty-eight patients were randomised, 66 in diclofenac and 62 in tramadol arm. The median area under the curve for graph of pain across time after first dose of pain medication for the diclofenac arm and the tramadol arm was 348.936 units (range: 113.64-1,969.23) and 420.87 (101.97-1,465.96), respectively, (p = 0.05619). Five patients (8.1%) in the tramadol arm and 11 patients (16.7%) in the diclofenac arm required a change in analgesic within 1 week of starting the analgesic (p = 0.184). There was no statistically significant difference in any adverse events between the two arms. However, the rate of any grade of renal dysfunction was numerically higher in the diclofenac arm (10.6% versus 4.8%, p = 0.326). CONCLUSION: In this phase 3 study, evaluating diclofenac and tramadol for chemoradiation induced mucositis pain, there was no statistical difference in analgesic activity of these two drugs.

BACKGROUND: Relapsed high-grade glioma has dismal outcomes. Mebendazole has shown promising activity against glioma in in-vitro and in-vivo studies. Hence, we undertook a phase 1 study to repurpose mebendazole in the treatment of glioblastoma. METHODS: We conducted a phase 1 study (accelerated titrated design 4) of mebendazole in patients with recurrent glioblastoma (GBM). Patients eligible for re-irradiation were enrolled in arm A1 (radiation with concurrent temozolomide 75 mg/m2 daily during the course of radiation+mebendazole) while patients who were ineligible were enrolled in either arm B1 (CCNU 110 mg/m2 day 1, every 6 weekly + mebendazole) or arm C1 (temozolomide 200 mg/m2 day 1-5, every 4 weekly + mebendazole). The primary endpoint of phase 1 was to identify the MTD of mebendazole in each combination. FINDINGS: 11 patients were enrolled in the whole study. MTD of mebendazole was not reached in arm A1 and C1 and hence the recommended dose for phase 2 was 1600 mg TDS (4800 mg) per day. The MTD of mebendazole in combination with CCNU was 1600 mg TDS (4800 mg) per day and the dose recommended for phase 2 was 800 mg TDS (2400 mg) per day. The three most common adverse events seen in the study were anemia (n = 9, 81.8%), nausea (n = 7, 63.6%), and fatigue (n = 6, 55.5%). INTERPRETATION: The recommended phase 2 dose of mebendazole is 1600 mg TDS with temozolomide and temozolomide-radiation combination while the dose of 800 mg TDS needs to be used with single-agent CCNU.

The focus of this review article is to throw light on non-conventional systemic chemotherapy that affects the tumour microenvironment and potentially has a favourable impact on the management of squamous cell cancer of the oral cavity. A metronomic combination of weekly methotrexate and celecoxib seems equally effective to single agent cisplatin in the palliative setting, but needs phase III testing. The same metronomic combination seems inferior to paclitaxel-cetuximab. Triple drug metronomic chemotherapy (methotrexate, celecoxib, and erlotinib) is still under development with promising data from pilot studies. Metronomic chemotherapy also seems beneficial in the curative setting but results of confirmatory studies are eagerly awaited. The low rate of adverse events and low cost make this regimen an attractive alternative. Both in vivo and in-vitro data suggests that numerous drugs like anthelmintics, DMARDs, antimalarials can be repurposed for Head and Neck Cancers. However, there is a dearth of clinical studies reported till date.
