The primary objective of the present randomized phase III trial was to compare the 3-yr survival rate of patients treated with standard fractionated radiotherapy RT alone or with the same RT concomitantly with cisplatin DDP or carboplatin Cb. There were no significant differences in complete response rates between patients treated with RT alone or combined chemoradiotherapy. However, median time to progression TTP and overall survival OS were significantly longer in patients treated with concomitant chemoradiotherapy. Thus, median TTP was 6. Similarly, median OS was

The Slippery Role of Induction Chemotherapy in Head and Neck Cancer: Myth and Reality

Chemoradiotherapy as an alternative to surgery can be offered to patients affected by loco-regionally advanced head and neck cancer HNC. Induction chemotherapy is a valid option, supported by few positive trials, but its real efficacy is still a matter of debate. Therefore, some less toxic combinations, such as a modified TPF regimen and the combination of carboplatin plus paclitaxel have been studied. These regimens are showing promising results but deserve further validation in comparative trials. Furthermore, several trials are underway in order to enhance TPF with immune checkpoints inhibitors. Compared to chemoradiotherapy, induction chemotherapy followed by chemoradiation was shown to be non-inferior, and it could decrease the distant metastatic progression, especially in high-risk populations. For selected patients, induction chemotherapy could be a strong option.

Head and neck squamous cell carcinoma HNSCC accounts for more than , new cancer cases and over , deaths each year worldwide. After intrinsic tumour suppressor mechanisms fail, further tumour progression is the result of an inefficient elimination phase or equilibrium phase of the extrinsic tumour suppression by the immune system. Thus, they become invisible to immune cells by reducing the presentation of tumour antigens, decreasing their sensitivity to the cytotoxic effects of immune cells, and rendering their microenvironment immunosuppressive. Besides a well-known immunosuppressive effect of radiotherapy RT , it can also lead to positive alterations in innate and adaptive immunity. This combination was shown to cause similar toxicity compared to either RT or ICI alone across different cancer types.

Treatment for patients with head and neck cancer requires a multidisciplinary approach. Radiotherapy is employed as a primary treatment or as an adjuvant to surgery. Each specific subsite dictates the appropriate radiotherapy techniques, fields, dose, and fractionation scheme. Quality of life is also an important issue in the management of head and neck cancer. The radiation-related complications have a tremendous impact on the quality of life.

Frequency distribution of time elapsed from the diagnosis of head and neck cancer to the initiation of radiotherapy among patients with regional A and local B tumors. Frequency distribution of the number of radiotherapy treatments received by patients with regional A and local B tumors. Arch Otolaryngol Head Neck Surg. For each case, we calculated the timing and duration of radiotherapy using Medicare claims data. Altogether,


radiotherapy (chemoradiotherapy) have improved survival among patients with head and neck cancer and especially those with HPV-.


Radiotherapy for Head and Neck Cancer

Metrics details. Definitive chemoradiotherapy dCRT is a standard treatment for patients with locally advanced head and neck cancer. There is a clinical need for a stratification of this prognostically heterogeneous group of tumors in order to optimize treatment of individual patients. Here we report the clinical results of the cohort which represent the basis for biomarker discovery and molecular genetic research within the framework of a clinical cooperation group.
