Frontiers in free flap reconstruction in the head and neck

Outcome of heavily pretreated recurrent oral squamous cell carcinoma after salvage resection: A monocentric retrospective analysis

PURPOSE

The goals of the present study were to analyze survival data of patients who received salvage surgery due to recurrent oral squamous cell carcinoma (OSCC) of the oral cavity with curative intent, and to investigate the feasibility of microvascular flap reconstruction in a heavily pretreated patient cohort.

MATERIAL AND METHODS

A total of 32 patients who received salvage surgery due to recurrent OSCC were included. The cohort was analyzed in regard to relevant clinical and pathological features. Survival was estimated by using Kaplan-Meier analysis and verified in a multivariate Cox regression model.

RESULTS

All patients recovered well from surgery. The most common severe complication was free flap failure in 7 patients (24.1%). R0-resection was achieved in 16 patients (50%). Univariate Kaplan-Meier analysis showed that the estimated overall survival and disease-free survival of all patients after 24 months were 37.8% and 30.9%, respectively. Multivariate testing identified R1-resection was the only independent predictor of treatment failure.

CONCLUSION

Salvage surgery is the only potential curative treatment option in recurrent OSCC. Microvascular reconstruction is feasible in heavily pretreated patients, but it is associated with a higher free flap failure rate. Recurrent OSCC in heavily pretreated patients shows different biological behavior. Further prospective clinical and molecular studies are needed to develop a better molecular understanding of recurrent OSCC and the best and safest individual therapeutic strategy.

Reconstructive Head and Neck Surgery: Oncological and Functional Results

Aims

The aim of this retrospective study is to review the experience in performing head and neck reconstruction surgery between 1989 and 2009 at the ENT Department of the University Hospital of Ferrara, Italy, considering the oncological as well as the functional and psychological outcome.

Methods and study design

Thirty-three consecutive patients were enrolled. Patients underwent flap reconstruction following primary or salvage surgery for squamous cell carcinoma of the oral cavity or oropharynx. Oncological results in terms of survival rate and disease-free interval, as well as functional and psychological results were evaluated.

Results

The oncological results, i.e. survival rate related to cancer stage and disease-free interval, were in agreement with those of the literature. Functional assessment, swallowing function and speech intelligibility were statistically poorer in patients affected by oropharyngeal malignancies than in patients affected by oral cancer. Quality of life was compromised in terms of reduced relationships and onset of depression or irritability.

Conclusions

Reconstructive surgery can be considered a relatively standard procedure in the treatment of head and neck cancer. The main drawback is still related to the major impact on patients' quality of life and functional status.

Current advances in facial reconstructive surgery following head and neck cancer surgery

There are currently a number of options in routine clinical use for facial reconstruction following ablative procedures, as well as several budding advances that may provide alternative approaches in the future. This review aims to give an overview of the current status of facial reconstruction as well as an introduction to the new developments.

Osteosarcomas of the mandible: are they different from other tumor sites?

BACKGROUND

Osteosarcomas of the mandible (MOS) affect 1/10 million persons/year, mostly the young adult. Due to lack of specific data, the treatment of MOS is extrapolated from that of extragnathic OS but varies widely between institutions.

MATERIALS AND METHODS

We aimed at providing a focused description of MOS histologies and grades through the English literature, at determining the evidence-based role of chemotherapy, of adjuvant radiation therapy and the potential of reconstructive surgery tailored through modern pre-operative multi-modal imaging.

RESULTS

The estimated proportion of high grade MOS was 58%. However, low-grade MOS may be underestimated as they are mostly reported as case reports. The intermediate grade was hardly found in the literature. Estimated weighted-mean proportions of chondroblastic and osteoblastic MOS were 37% and 46%, respectively. Multimodal imaging modalities including MRI has a great potential for accurate pre-operative assessment of tumor extensions into bone and soft tissues. Surgery is the mainstay of treatment and margins the most important factor. The role of neoadjuvant chemotherapy in treating occult systemic metastases and in increasing the probability of clear margins is controversial, as well as the histology-dependent response to chemotherapy. The role of adjuvant radiotherapy (mostly proposed for positive margins) and/or adjuvant chemotherapy is still controversial. Crude survival is around 77% and local control around 67%. Local failure is the main cause of death in MOS compared to extragnathic sites.

Head and neck oncology--2010, part II

Part II this article reviewed the current state of the art in head and neck oncology. These include very important and stimulating new areas of interest including the marked acceptance of chemoradiation in favor of surgery in patients with cancer of the head and neck. The concept of HPV as a cause of cancer of the oropharynx is relatively new and very important in the epidemiology of these tumors. New modalities such as PET CT scanning and robotic surgery are discussed and appear to be very important in management of cancer of the head and neck. Endoscopic endonasal skull base surgery is another new high technology contribution to the field of head and neck surgery as is the use of endoscopic assisted thyroid surgery. These and other new concepts are discussed in this manuscript.
