Common Mutation

Recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) patients overall have a poor prognosis. However, human papillomavirus (HPV)-associated R/M oropharyngeal squamous cell carcinoma (OPSCC) is associated with a better prognosis compared to HPV−negative disease. Immune checkpoint blockade (ICB) is the standard of care for R/M HNSCC. However, whether HPV and its surrogate marker, p16, portend an improved response to ICB remains controversial. We queried the Caris Life Sciences CODEai database for p16+ and p16− HNSCC patients using p16 as a surrogate for HPV. A total of 2905 HNSCC (OPSCC, n = 948) cases were identified. Of those tested for both HPV directly and p16, 32% (251/791) were p16+ and 28% (91/326) were HPV+. The most common mutation in the OPSCC cohort was TP53 (33%), followed by PIK3CA (17%) and KMT2D (10.6%). TP53 mutations were more common in p16− (49%) versus the p16+ group (10%, p < 0.0005). Real-world overall survival (rwOS) was longer in p16+ compared to p16− OPSCC patients, 33.3 vs. 19.1 months (HR = 0.597, p = 0.001), as well as non-oropharyngeal (non-OP) HNSCC patients (34 vs. 17 months, HR 0.551, p = 0.0001). There was no difference in the time on treatment (TOT) (4.2 vs. 2.8 months, HR 0.796, p = 0.221) in ICB-treated p16+ vs. p16− OPSCC groups. However, p16+ non-OP HNSCC patients treated with ICB had higher TOT compared to the p16− group (4.3 vs. 3.3 months, HR 0.632, p = 0.016), suggesting that p16 may be used as a prognostic biomarker in non-OP HNSCC, and further investigation through prospective clinical trials is warranted.

Neck Squamous Cell Carcinoma

Leczenie chorych na raka płaskonabłonkowego głowy i szyi jest istotnym problemem. Obserwuje się wzrost zachorowalności na nowotwory złośliwe tego regionu. Chirurgia, radioterapia oraz chemioterapia często nie są wystarczającymi metodami leczenia. Dokładna analiza procesów zachodzących w mikrośrodowisku guza pozwoliła na wyodrębnienie trzech etapów składających się na reakcję organizmu człowieka na wrogie antygeny, jakimi są antygeny nowotworowe. Poznanie tych mechanizmów skutkowało wprowadzeniem nowego terminu immunoonkologia. Jest to dziedzina leczenia nowotworów skupiająca się na wykorzystaniu układu immunologicznego pacjenta w celu zwalczania choroby. Immunoterapia u chorych na raka przyniosła pozytywne efekty. Wykorzystanie inhibitorów immunologicznych punktów kontroli, jak przeciwciała monoklonalne przeciwko receptorowi CTLA – 4 oraz PD – 1 umożliwiło modulację funkcji limfocytów T w konsekwencji znosząc immunosupresję w mikrośrodowisku guza. Przeprowadzono badania kliniczne z zastosowaniem nivolumabu oraz ipilimumabu, które potwierdziły ich przydatność kliniczną. Zatwierdzenie przez FDA nivolumabu w leczeniu nawrotowego i przerzutowego raka płaskonabłonkowego głowy i szyi wydłużyło całkowity czas przeżycia chorych oraz czas przeżycia wolny od choroby. Dane statystyczne wskazują na przewagę immunoterapii nad innymi metodami leczenia w zaawansowanym stadium choroby nowotworowej. Celem pracy jest omówienie podstawowych zagadnień związanych z immunoterapią, w szczególności immunoterapią u chorych na raka płaskonabłonkowego głowy i szyi.

Programmed Death

In addition to surgery, chemotherapy, radiotherapy, and targeted therapy, immunotherapy has emerged as a standard pillar of cancer treatment. Immune checkpoint inhibitors (ICIs) such as targeting programmed death-1/programmed death ligand 1 (PD-1/PD-L1) and cytotoxic T lymphocyte antigen 4 (CTLA-4) have been integrated into standard-of-care regimens for patients with advanced lung squamous cell carcinoma (LUSC), who were previously limited by the lack of treatment options. Atezolizumab, durvalumab, nivolumab, and pembrolizumab are all currently used as part of standard-of-care treatment for different stages of lung cancer. Recent successes and failures of immune checkpoint blockade-based combination therapies have provided significant insights into implementing combination strategies in LUSC. Therefore, there is an urgent need to correctly select patients who are more likely to respond to immunotherapy and understand the mechanisms of primary or acquired resistance. In this review, we aim at summarizing the emerging clinical data on the promise and challenge of ICIs, discussing the unmet need of potential biomarkers for predicting response or resistance to immunotherapy, and providing an overview of the current immune landscape and future directions in advanced LUSC.
