Clinical Predictors of Laryngeal Preservation Rate in Stage III-IV Laryngeal Cancer and Hypopharyngeal Cancer Patients Treated with Organ Preservation.

Clinical Predictors of Laryngeal Preservation Rate in Stage III-IV Laryngeal Cancer and Hypopharyngeal Cancer Patients Treated with Organ Preservation. Asian Pac J Cancer Prev. 2019 Jul 01;20(7):2051-2057 Authors: Tangsriwong K, Jitreetat T Abstract PURPOSE: To determine factors affecting laryngeal preservation rate in laryngeal and hypopharyngeal cancer patientstreated with organ preservation. MATERIAL AND METHODS: Retrospective study examining stage III to IV laryngeal andhypopharyngeal cancer patients who have been treated with organ preservation. Conventional radiation must be appliedin all patients with minimum dose of 45 Gray. Weekly or triweekly chemotherapy can be adding during radiation. Salvagesurgery should be considered in residual disease or local recurrence. Kaplan-Meier was used for survival analysis and,Log rank test and Cox proportional hazard test were used for uni and multivariate analysis. RESULTS: From January2010 to October 2014, there were 69 patients treated with laryngeal preservation and 53 patients received radiationdose 61-70 Gray. After completing radiation, we found that 44 patients have no residual tumor within 6 months and33 patients can preserve their functional larynx later with complete response (median follow up 6 mo, range 0-46.3mo). The 1-year, 2-year and 3-year laryngeal preservation rate was 49%, 36 % and 32 % respectively. On univariateanalysis, lower nodal stage (p = 0.008), stage III disease (p = 0.046), ...

ConclusionsA single-cycle induction chemotherapy for HNSCC enables surgery plus adjuvant therapy as well as chemoradiotherapy. The long-term local and distant disease control was good but varied between tumors in the larynx and mesopharynx/tongue vs. hypopharynx.

ConclusionsThese preliminary results suggest a promising response to single cycle induction treatment with cisplatin/ docetaxel plus durvalumab/ tremelimumab in unselected HNSCC patients. Furthermore, they show an induction of an immune response in both in the tumor tissue and the peripheral blood.Clinical trial identificationNCT03426657.Legal entity responsible for the studyThe authors.FundingAstraZeneca.DisclosureM.

AbstractBackgroundThe presence of high levels of tumor immune infiltrate has been recognized to be associated with better prognosis in Head and Neck cancer (H&N). The consensus Immunoscore quantifies the densities of CD3 and CD8 in the center of the tumour (CT) and the invasive margin (IM) and stratifies patients into 3 Immunoscore categories (Low, Intermediate and High).

CONCLUSIONS: Definitive carboplatin-based chemoRT was equivalent to cisplatin-based therapy and superior to RT alone and RT with concurrent cetuximab. In light of recent results of the RTOG 1016 and De-ESCALaTE trials, our findings suggest that carboplatin-based regimens warrant prospective investigation as an alternative to cisplatin for patients who are not cisplatin candidates.

Nature Reviews Clinical Oncology, Published online: 12 June 2019; doi:10.1038/s41571-019-0227-zThe authors of this Review discuss treatments currently available for patients with head and neck squamous cell carcinomas (focusing in those of the oral cavity, oropharynx, hypopharynx and larynx). Advances in surgical and non-surgical approaches (mainly combinations of radiotherapy and chemotherapy) are discussed, including the first immunotherapeutic agents approved for these malignancies.

AbstractPurposeThe present work aims at evaluating intensity-modulated radiation therapy with simultaneous integrated boost (IMRT-SIB) in squamous cell carcinomas (SCC) of the larynx and hypopharynx.Methods/patientsWe performed a single institutional retrospective analysis on 116 pharyngo (29%)-laryngeal (71%) SCC patients (93% male) treated with IMRT-SIB to 66 –69.96 Gy in 33 fractions between 2008 and 2016. Those who underwent surgery (54%) received adjuvant radiation of 66 Gy at 2 Gy/fraction to the surgical bed. 16 patients (14%) were treated for a local recurrence after prior surgery. High-risk ly...

CONCLUSIONS: These data suggest that HPV status may be a prognostic factor in patients with T4a LSCC. Further, it supports further investigation into the usefulness of HPV status as a selection factor for larynx preservation with CRT in these patients.

For long, the treatment of locoregionally laryngeal and hypopharyngeal squamous cell cancer consisted of either total laryngectomy (TL) or radical radiotherapy (RT). The appearance of induction cisplatin/5fluorouracil (PF) and the correlation between chemo and radiosensitivity in previously untreated patients opened a new era of treatment aiming at larynx preservation (LP). The concept was to select patients to either TL or RT according to the tumour response to induction PF. The first two trials (VALGSG for larynx SCC and EORTC 24891 for hypopharynx SCC) concluded that such an approach could preserve nearly 60 % of lar...

Conclusions In the span of a very short time—less than a decade—robotic head and neck surgery has transformed the management of the head and neck cancer, and it seems clear that the future of treatment for these cancers lies in a multimodal approach in which TORS is likely to play an important role. Nevertheless, it is important to keep in mind that the current indications for TORS are limited and long-term data on the safety and oncological outcomes are needed to better understand the true role of TORS in treatment of head and neck cancer. Nonetheless, the emergence of ever more advanced robotic instruments i...
