Tobacco-related neoplasms: survival analysis and risk of death of population data from Florianópolis, SC

OBJECTIVE

To estimate the probability of survival and prognostic factors for tobacco-related neoplasms in a population-based cohort.

METHODS

This is a cohort with data from the Population-Based Cancer Registry of Florianópolis, southern Brazil, from 2008 to 2012. The Stata 16.0 software was used to estimate the probabilities of survival in five years after diagnosis, by the Kaplan Meier method, and the risk of death, by the Cox regression.

RESULTS

A total of 2,829 cancer records related to smoking were included, more prevalent among males, over 70 years of age, nine years or more of schooling, white, with a partner and metastatic diagnosis. The most frequent groupings were colon and rectum (28.7%), trachea, bronchi and lungs (18.6%) and stomach (11.8%). At follow-up, 1,450 died. Pancreatic cancer had the worst probability of survival (14.3%), followed by liver cancer (19.4%).

CONCLUSION

Risk factors for death and survival rates differ across the 13 types of tobacco-related cancers. Early diagnosis and primary prevention are strategies that must be improved to improve survival and decrease the burden related to these types of cancer.

Comparison of Patients With Total and Salvage Laryngectomy

INTRODUCTION AND OBJECTIVES

Total laryngectomy (TL) is one of the treatments available in locally advanced laryngeal carcinomas or as a salvage therapy when organ preservation fails, achieving high survival rates and few complications. The aim of this study was to analyse the oncological outcomes, comparing the data obtained with the current literature and analysing complications and survival.

METHODS

The study included 62 patients with primary carcinoma of the larynx treated by primary or salvage TL between 2003 and 2019. We analysed the demographic, clinical and pathological characteristics, tumour stage, complementary treatments, postoperative complications, locoregional recurrences, metastases, and causes of death.

RESULTS

The mean age was 64 years, 90.3% were men, 96.8% were smokers, 43.5% had multiple pathologies and 82.3% had a locally advanced stage. Of all TL 71% were primary and 29% salvage. Neck dissection was performed in 59.6%. Lymphovascular invasion was present in 30.6%, perineural invasion in 30.6% and margin involvement in 14.5%. During the follow-up, 17.7% presented locoregional recurrence and 11.3% distant metastases. Regarding complementary treatments, 56.4% of the patients received adjuvant therapy. The incidence of haemorrhage was 11.3%, infection 14.5%, and pharyngocutaneous fistula 21%. There was a statistically significant correlation between fistula and haemorrhage (P = .000) and between fistula and infection (P = .000). No statistically significant differences were found between the studied factors of primary and salvage TL. The 3-year overall survival was 92% and 5-year overall survival was 88%, finding statistical significance with the locally advanced stage (P = .038), T4 (P = .026), lymphovascular invasion (P = .019) and the involvement of more than 3 lymph nodes in the pathological anatomy (P = .005). On the multivariate analysis, the only variable that showed a significant relationship with survival was lymphovascular invasion (P = .026).

CONCLUSIONS

Although organ preservation is a primary objective, TL remains a leading treatment in locally advanced carcinomas and as salvage in case of failure of medical therapy or partial surgery.

Closing of large pharyngostomes with free flaps and proposal of a new classification

PURPOSE

Large pharyngocutaneous fistulas or pharyngostomes are difficult complications to solve, which generate high morbidity and mortality, a poor quality of life and an increase in health costs. Its management must be comprehensive according to general, local and regional factors. We review our experience in treating these pharyngostomes with free flaps.

METHODS

Retrospective study analyzing the results of the reconstruction of 50 patients using free flaps during the period 1991-2019. We exclude patients who required free-flap reconstruction due to primary tumor or those who resolved in other ways. The different types of reconstruction were classified into three types.

RESULTS

The 86% (43) were men, and the mean age was 57 years (25-76). In 48% (24/50) the flaps performed were anterolateral thigh (ALT), in 24% (12/50) forearm, in 22% (11/50) parascapular, in 4% (2/50) jejunum and in 2% (1/50) ulnar. A salivary by-pass was placed in 74% (37/50) of the cases. Four cases (8%) presented flap necrosis and two patients died due to treatment. In 86% (43/50) there was some type of complication and 34% (17/50) required surgical revision. 94% (45/48) were able to reintroduce oral feeding.

CONCLUSION

According to our experience, we proposed a regardless size classification: type 1 when only a mucous closure (pharynx) are required (6%), type 2 exclusively skin for cutaneous coverage (10%) and mixed type 3 (mucous and skin) (84%). The treatment of large pharyngostomes with free flaps, despite its complexity, is in our experience the best option for its management.

Matched-pair analysis of survival in the patients with T3 laryngeal squamous cell carcinoma treated with supracricoid partial laryngectomy or total laryngectomy

Background

The survival outcomes between supracricoid partial laryngectomy (SCPL) and total laryngectomy (TL) were compared in the groups of matched-pair patients with T3 laryngeal squamous cell carcinoma (LSCC).

Methods

Patients with T3 LSCC were matched based on prognostic factors. The Kaplan–Meier curve and the Cox proportional hazards model were used for analysis on survival.

Results

A total of 212 patients with T3 LSCC were included after matching (106 underwent SCPL and 106 underwent TL). Multivariable analysis showed no differences in overall survival (hazard risk [HR]=1.15; 95% CI: 0.79–1.67; P=0.47), disease-specific survival (HR=1.11; 95% CI: 0.69–1.80; P=0.66), and recurrence-free survival (HR=1.07; 95% CI: 0.68–1.68; P=0.77) between the SCPL group and TL group.

Conclusion

SCPL provides reliable therapeutic outcomes and can be used to avoid a TL surgery in some patients with advanced primary laryngeal cancer.

Rehabilitation of the laryngectomised patient. Recommendations of the Spanish Society of Otolaryngology and Head and Neck Surgery

Total laryngectomy remains essential treatment for locally advanced laryngeal carcinoma, related to better survival rates. However, it involves changes for the patient, such as the inability to communicate verbally, breathing or aesthetic changes, which affect their quality of life and require comprehensive rehabilitation. This paper was written by the total laryngectomy rehabilitation workgroup of the National Head and Neck and Skull Base working committee of the Spanish Society of Otolaryngology and Head and Neck Surgery. The purpose of the article is to combine materials, surgical procedures and means towards the comprehensive rehabilitation of total laryngectomy patients, so that they can achieve a good quality of life. This paper is aimed at all health care professionals caring for total laryngectomy patients. It is also aimed at the patients themselves, as well as ENT surgeons. We have considered staffing and material needs, all procedures before, during and after surgery and after hospital discharge. There are also detailed recommendations about types of rehabilitation and follow-up, and the need for recording these events. The comprehensive rehabilitation total laryngectomy patients is very important if we want to improve their quality of life. The recommendations we mention aim to help the healthcare professionals involved in the treatment of total laryngectomy patients to help them achieve a good quality of life, as similar as possible to the life they led before surgery.

Results of total laryngectomy as treatment for locally advanced hypopharyngeal cancer

INTRODUCTION AND OBJECTIVES

Total laryngectomy (TL), with eventual postoperative radiotherapy, has proven to be effective in treating cases of locally advanced hypopharyngeal cancer. The aim of this study was to analyse the oncological outcomes of this procedure in patients with hypopharyngeal cancer classified T3 and T4.

METHODS

We studied 59 patients (33 T3 and 26 T4a) with primary squamous cell carcinoma of the hypopharynx treated with TL from 1998 to 2012.

RESULTS

Mean age was 61 years with a male predominance (96.6%). All the patients were smokers and 96% consumed alcohol. Unilateral selective neck dissection (ND) was performed in 12 patients, unilateral radical ND in 11 patients, bilateral selective ND in 20 patients and radical ND plus selective ND in 14 patients. 66% of the patients received postoperative radiotherapy. Lymph node metastases occurred in 81% of the patients and extranodal invasion in 56% of them. 29% of the patients had loco-regional recurrence, 17% developed distant metastases, and 25% a second primary tumour. The 5-year disease-specific survival was 46%.

CONCLUSIONS

TL extended to pharynx (with eventual postoperative radiotherapy) offers good oncological results in terms of loco-regional control and survival in locally advanced hypopharyngeal cancer, so organ preservation protocols should achieve similar oncological results to those shown by TL.

Clinical and histopathological prognostic factors in locoregional advanced laryngeal cancer

Objective:

To evaluate the clinical and histopathological factors affecting the prognosis of patients with squamous cell locoregional advanced laryngeal cancer.

Methods:

A retrospective chart review was conducted of 121 patients with locoregional advanced laryngeal cancer, primarily treated with surgery from 2007 to 2011. Disease-free survival and overall survival rates were analysed as oncological outcomes. Prognostic variables, namely gender, pharyngeal invasion, pathological assessment of tumour and nodal stage, adjuvant therapy, margin status, nodal extracapsular extension, tumour differentiation, lymphovascular and perineural invasion, and predominant growth pattern, were also analysed.

Results:

One-year and three-year disease-free survival rates were 81.3 per cent and 63.5 per cent, respectively. One-year and three-year overall survival rates were 88.3 per cent and 61.4 per cent, respectively. Multivariate analysis showed that nodal extracapsular extension (p < 0.05) and an infiltrative growth pattern (p < 0.05) were associated with disease progression. Nodal extracapsular extension (p < 0.05) was associated with higher mortality.

Conclusion:

Nodal extracapsular extension and an infiltrative growth pattern were the main prognostic factors in locoregional advanced laryngeal cancer. The presence of pharyngeal invasion, pathologically confirmed node-positive stage 2–3 disease, close or microscopic positive margins, and lymphovascular and perineural invasion have a negative impact on prognosis.
