Current Approaches to Salvage Surgery for Head and Neck Cancer: A Comprehensive Review.

Salvage surgeries of head and neck cancer are often complicated and do not always show decent results. This type of procedure is tough on the patient, as many crucial organs can be affected. A long period of reeducation usually follows the surgery because of the need to rehabilitate functions such as speech or swallowing. In order to lighten the journey of the patients, it is important to develop new technologies and techniques to ease the surgery and limit its damages. This seems even more crucial since progress has been made in the past years, allowing more salvage therapy to take place. This article aims at showing the available tools and procedures for salvage surgeries, such as transoral robotic surgery, free-flap surgery, sentinel node mapping, and many others, that help the work of the medical team to operate or obtain a better understanding of the status of the cancer when taken in charge. Yet, the surgical procedure is not the only thing determining the outcome of the operation. The patient themself and their cancer history also play an important part in the care and must be acknowledged.

[Surgical de-escalation for head and neck cancer surgery]. / Désescalade en chirurgie oncologique cervico-faciale.

Head and neck cancer surgery often has functional and aesthetic consequences. De-escalation surgery is a major concern for surgeons with a constant desire to develop surgical techniques with less invasive approaches and to preserve anatomical structures as much as possible. This was made possible by the appearance of minimally transoral and endonasal surgery as well as by the limitation of the surgical procedure by neoadjuvant treatments or by the limitation of surgical excision without compromising the oncological outcome and patient survival. This evolution continues with the arrival of new technologies such as virtual reality or artificial intelligence.

Estimating the risks and benefits before salvage surgery for recurrent head and neck squamous cell carcinoma.

INTRODUCTION: The risks associated with salvage surgery of head and neck squamous cell carcinoma (SCC) in a previously irradiated field needs to be balanced against the expected survival benefits. We want to identify preoperative predictive factors for overall and disease-specific survival (OS/DSS) and for the development of serious (Clavien-Dindo, CD≥III) complications following salvage surgery for radiorecurrent SCC to help surgeons, patients, and caregivers in the decision-making process in this setting. MATERIALS AND METHODS: The records of 234 patients presenting to the Lorraine Cancer Institute with locoregional radiorecurrent SCC were reviewed. The primary endpoint was OS, secondary endpoints were DSS, OS without tracheostomy/gastrostomy, and the risk of CD≥III complications. Multivariate analyses were carried out to explore preoperative factors associated with survival and the risk of postoperative complications. RESULTS: With a median follow-up time of 19 months, 5-year OS since the first salvage surgery was 28.3%, 5-year DSS was 38.9%. 2- and 5-year functional OS were 45.6% and 27.2%. rcT-rcN, and WUNHCI ≥4 were both independent significant preoperative predictors of OS and DSS. 30-days postoperative complications occurred in 44.4% of patients (28 CD I, 24 CD II, 34 CD III, 11 CD IV, 7 CD V). A salvage procedure involving T+N plus the presence of a WUHNCI ≥4 was the only independent predictor of CD≥III complications. CONCLUSION: When discussing with the patients and the caregivers salvage surgery for recurrent head and neck SCC, a careful evaluation of the preoperative comorbidities by the WUHNCI tool can reliably predict the expected risks and benefits from the procedure.

Partial pharyngolaryngectomy with infrahyoid flap: Our experience.

AIM: We evaluated a cohort of advanced hypopharyngeal squamous cell carcinoma, treated with conservative surgery, reconstruction with infrahyoid flap and radio-chemotherapy. METHODS: We used partial pharyngo-laryngectomy and radio-chemotherapy to treat fifty-seven patients with stage III-IV hypopharyngeal SCC from November 1994 to December 2011. Clinical examination and speech therapy evaluation were used for estimation of laryngeal function. RESULTS: All patients received a partial pharyngo-laryngectomy. All patients underwent neck dissection; 56 patients received bilateral neck dissection. Reconstruction was achieved by infra-hyoid flap. Five-year overall and disease-specific survival rates were 54.4% and 61.4%, respectively. Successful laryngeal function preservation with complete five-year remission was achieved in 44% of the patients. CONCLUSION: Selected even if advanced carcinomas of the hypopharynx maybe treated with partial pharyngo-laryngectomy with reconstruction with pedicled flap. Both oncological and functional results showed a good outcome.
